D. Risk Factors

Our business involves a high degree of risk. You should consider carefully the risks described below, together with the financial and other information contained in this annual report and our other filings with the SEC. If any of the following risks actually occurs, our business, financial condition and results of operations would suffer. In this case, the trading price of our ordinary shares would likely decline and you might lose all or part of your investment. The risks described below are not the only ones we face. Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business operations.

Risks Relating to Our Business

We have a history of losses and may not be able to achieve or maintain profitability in the future.

We have a history of net losses in all fiscal years since our inception, other than in 2006 and 2011. We had a net loss of $18.1 million in 2017, resulting mainly from a decrease in both products revenues and services revenues of $8.4 million, restructuring expenses of $2.4 million, changes in tax related items of $1.7 million and the impact of the weakening of the U.S. dollar mainly against the ILS and Euros. We had a net loss of $8.0 million in 2016, resulting mainly from a decrease in both products revenues and services revenues. We had a net loss of $19.8 million in 2015, resulting mainly from impairment charge of $5.8 million, tax expenses which amounted to $3.4 million (including $2.7 million of deferred tax asset and pre-paid tax expenses write-off) and a decrease in product revenues. We can provide no assurance that we will be able to achieve or maintain profitability, and we may incur losses in the future if we do not generate sufficient revenues.

Our revenues and business may be adversely affected if we do not effectively compete in the markets in which we operate.

We compete against large companies in a rapidly evolving and highly competitive sector of the networking technology and security markets, which offer, or may offer in the future, competing technologies, including partial or alternative solutions to operators' and enterprises’ challenges, and which, similarly to us, intensely pursue the largest service providers (referred to as Tier 1 operators) as well as large enterprises. Our ability to effectively compete in these markets may be limited since our competitors may have greater financial resources, significant market share and established relationships with operators and distribution channels.

Our Deep Packet Inspection (DPI) technology enabled offerings face significant competition from router and switch infrastructure companies that integrate functionalities into their platforms, addressing some of the same types of issues that our products are designed to address. In addition, increased network encryption could limit the ability of our DPI solutions to provide analytic information.

Our security products are offered to operators and are deployed in their networks, enabling them to provide security services to their end customers. Such products face significant competition from companies that directly approach end customers and offer them security applications to be installed on their devices; companies that approach the business enterprise sector through distribution channels and offer cloud security products; and companies that offer security products bundled with other products. By offering our security products to operators that provide security services to both business enterprises and individual end customers, we aim to expand the reach of our products. However, such business model may prove to be slower to market or less effective than our competitors' models, in which case our business may be harmed.

Certain of our current direct competitors are substantially larger than we are and have significantly greater financial, sales and marketing, technical, manufacturing and other resources. As the intelligent broadband solutions market has grown, including the markets for DPI enabled solutions for mobile networks and for security products, new competitors have entered and may continue to enter the market. Furthermore, our market is subject to industry consolidation, as companies attempt to maintain or strengthen their positions in our evolving industry. Some of our current and potential competitors have made acquisitions or have announced new strategic alliances designed to position them to provide many of the same products and services that we provide to both the service provider and enterprise markets, such as the recent Sandvine – Procera transaction, which resulted in a combined company positioned to compete with us in the fields of analytics, policy charging and control, traffic management, security, regulatory compliance and cloud managed services. Industry consolidation may result in stronger competitors that are better able to compete as sole-source vendors for customers, may cause price reductions, reduced gross margins and loss of market share.

If our competitors announce new products, services or enhancements that better meet the needs of customers or changing industry requirements, offer alternative methods to achieve customer objectives or implement faster go to market strategies, if our business model proves less effective than those of our competitors, if new competitors enter the market, or if industry consolidation results in stronger competitors with wider range of product offerings and greater financial resources, our ability to effectively compete may be harmed, which could have a material adverse effect on our business, financial condition or results of operations.

We depend on one or more significant customers and the loss of any such significant customer or a significant decrease in business from any such customer could harm our results of operations.

We derived 32% of our total revenues in 2017 from one Tier 1 mobile and fixed operator. In 2016 and 2015, we derived 42% and 37% of our total revenues from two Tier 1 mobile and fixed operators, respectively. In addition, revenues from individual customers may fluctuate from time to time based on the timing and the terms under which orders are received and the duration of the delivery and implementation of such orders, potentially resulting in decreases in revenues from such customers. The loss of any significant customer or a significant decrease in business from any such customer could have a material adverse effect on our revenues, results of operations and financial condition.

Demand for our products may be impacted by government regulation of the telecommunications industry.

Service providers are subject to government regulation in a number of jurisdictions in which we sell our products. There are several proposals in the United States, Europe and elsewhere for regulating service providers’ ability to prioritize applications in their networks. Advocates for regulating this industry claim that collecting premium fees from certain “preferred” applications would distort the market for Internet applications in favor of larger and better-funded content providers. They also claim that this would impact end-users who already purchased broadband access only to experience response times that differ based on content provider. Opponents believe that content providers who support bandwidth-intensive applications should be required to pay service providers a premium in order to support further network investments.

On December 14, 2017 the United States Federal Communications Commission (the “FCC”) announced that it voted to repeal the Open Internet Report and Order on Remand, Declaratory Ruling, and Order (the “Open Internet Order”). The Open Internet Order was issued by the FCC and went into effect on June 12, 2015. The Open Internet Order sets forth rules, grounded, among others, on Title II of the Communications Act of 1934; the Open Internet Order regulates both fixed and mobile Internet Service Providers (ISPs) and prohibits them, subject to reasonable network management, from blocking and/or throttling of lawful content, applications, services, or non-harmful devices, and from unreasonably interfering or disadvantaging of (i) end users’ ability to select, access service of the lawful Internet content, applications, services, or devices of their choice or (ii) edge providers’ ability to make lawful content, applications, services, or devices available to end users. The Open Internet Order also prohibits paid prioritization of content. The approved proposal to repeal the Open Internet Order would largely reverse the Open Internet Order, including the classification of broadband Internet service as a telecommunications service, which is subject to certain common carrier regulations, and restore the regulatory framework, which preceded the Open Internet Order. Because our products allow ISPs to identify network traffic and facilitate traffic management, the reinstatement of this traditional regulatory framework may affect ISP's demand for certain of our products. However, the repeal of the Open Internet Order will only take effect upon approval of the revised transparency rule by the Office of Management and Budget and may also be reversed by Congress, by a resolution of disapproval, under the Congressional Review Act. Therefore, the impact of the FCC's approved proposal on the demand for our products is uncertain and difficult to assess at this time.

On April 30, 2016, Regulation (EU) 2015/2120 of the European Parliament and of the Council came into effect, setting forth the first EU-wide Net Neutrality (“Open Internet”) rules. Under these rules, blocking, throttling and discrimination of internet traffic by ISPs is prohibited in the EU, with three exceptions: (i) compliance with legal obligations; (ii) integrity of the network; and (iii) congestion management in exceptional and temporary situations. Under these rules, there can be no prioritization of traffic in the internet access service. However, equal treatment permits reasonable day-to-day traffic management according to objectively justified technical requirements, and which must be independent of the origin or destination of the traffic and of any commercial considerations. However, these rules also allow internet access providers, as well as content and applications providers, to offer special services with specific quality requirements, (provided the Open Internet is not negatively affected by the provision of these services). Such specialized services cannot be a substitute to internet access services, can only be provided if there is sufficient network capacity to provide them in addition to any internet access service and must not be to the detriment of the availability or general quality of internet access services for end-users.

Such regulation of both fixed and mobile ISPs, in affected EU jurisdictions, may limit ISPs' ability to manage, prioritize and monetize their network. Additionally, these regulations may attract growing public debate and attention of regulators in other jurisdictions we operate in. Demand from service providers, in affected jurisdictions, for the traffic management and subscriber management features of our products may be adversely affected by such regulations. A decrease in demand for these features could adversely impact sales of our products and could have a material adverse effect on our business, financial condition or results of operations.

In addition, strict data privacy laws regulating the collection, transmission, storage and use of employee data and consumers' personally-identifying information applicable to ISPs are evolving in the US, European Union and other jurisdictions in which we sell our products. For example, in the U.S., legislation has in recent years been proposed regarding restrictions on the use of geolocation information collected by mobile devices without consumer consent. Similarly, the General Data Protection Regulation (“GDPR”), coming into effect in the European Union in May 2018, creates a range of new compliance obligations, increases financial penalties for non-compliance and extends the scope of the E.U. data protection law to all companies processing data of E.U. residents, regardless of the company’s location. The GDPR and other privacy and data protection laws may be interpreted and applied differently from country to country and may create inconsistent or conflicting requirements. Such regulations increase our customers' compliance and administrative burden significantly and may require us to adapt certain of our products, if necessary, to different requirements in various E.U. countries, as well as in the US, in order to allow our customers in such jurisdictions, to comply with such regulations. There is also no assurance that we will be able to adapt our products sufficiently in order to allow our customers in various jurisdictions to comply with such regulatory requirements in each jurisdiction.

As data protection and privacy-related laws and regulations continue to evolve, these changes may result in increased regulatory and public scrutiny, escalating levels of enforcement and sanctions and increased costs of compliance. Therefore, we may be required to modify the features and functionalities of certain of our products, in a manner that is less attractive to customers. Such adjustments of our products, if required, may require extensive financial investments and may take long periods of time, leading to delay in sales cycles, deployment of our products and recognition of related revenues.

We need to continue to increase the functionality of our products and offer additional features and products to maintain or increase our profitability.

The commoditization of DPI technology and the introduction of competitive features and services will result in a decrease of the average sale prices of our DPI technology enabled products.

The market in which we operate is highly competitive and unless we continue to enhance the functionality of our products, add additional features and offer additional products, our competitiveness may be harmed.

We seek to enhance our products by offering higher system speeds, additional features and products, such as security and parental control products, and support for additional applications and enhanced reporting tools. We also continuously endeavor to assure our solutions comply with contemporary network and software architectures such as virtualized network services (NFV).

Our products offer customers additional tools to increase the efficiency of their networks or to help them offer additional services to their end customers and derive additional revenues from their end customers. The industry and market for our products are still developing and are affected, among others, by trends and changes in internet broadband traffic, including changes in methods used by various content providers and broadband applications and evolution of network security threats.

We cannot provide any assurance that demand for our additional features and products will continue or grow, or that we will be able to generate revenues from such sales at the levels we anticipate or at all. Any inability to sell or maintain our additional features and products may lead to commercial disputes with our customers and increased spending on technical solutions, any of which may negatively impact our results of operations.

Our revenues and business will be harmed if we do not keep pace with changes in broadband applications, network security threats and with advances in technology, or if we do not achieve widespread market acceptance, including through significant investments.

We will need to invest heavily in the continued development of our technology in order to keep pace with rapid changes in applications, increased broadband network speeds, network security threats and with our competitors’ efforts to advance their technology. Our ability to develop and deliver effective product offerings depends on many factors, including identifying our customers’ needs, technical implementation of new services and integration of our products with our customers’ existing network infrastructure. While we will continue to introduce innovative products, we cannot provide any assurance that any new products we introduce will achieve the same degree of success that we have with our existing products. Designers of broadband applications and distributors of various network security threats that our products identify, manage or mitigate are using increasingly sophisticated methods to avoid detection and management and/or mitigation by network operators.

Even if our products successfully identify a particular application, it is sometimes necessary to distinguish between different types of traffic belonging to a single application. Accordingly, we face significant challenges in ensuring that we identify new applications and new versions of current applications as they are introduced, without impacting network performance, especially as networks become faster. This challenge is increased as we seek to expand sales of our products to new geographic territories because the applications vary from country to country and region to region.

The network equipment market is characterized by rapid technological progress, frequent new product introductions, changes in customer requirements and evolving industry standards. To compete, we need to achieve widespread market acceptance. Alternative technologies could achieve widespread market acceptance and displace the technology on which we have based our product architecture. Our business and revenues will be adversely affected if we fail to develop enhancements to our products, in order to keep pace with changes in broadband applications, network security threats and advances in technology. We can give no assurance that our technological approach will achieve broad market acceptance or that other technology or devices will not supersede our technology and products.

A failure of our products may adversely affect the operation of our customers' live networks or the quality and scope of service to our customers and their end users, which could harm our reputation, brand position, and financial condition.

Our products are, generally, installed in line as part of our customers' networks and provide a wide range of services that our customers may offer to their own customers. We endeavor to avoid any interruption to the regular operation of our customers’ networks, any reduction of quality of services or failure to provide the quality and/or scope of services to users, including, by performing certain tasks during predetermined maintenance windows, and implementing a system bypass, in the event of malfunctions. However, in certain cases, a failure of our products may result in our customers experiencing loss of functionality, denial of service and access, interruption of live traffic on our customers’ networks, loss of security protection or inability to provide similar services to our customers’ end users. Such failure of our products, may cause disputes with our customers, adversely affect our reputation, and lead to loss of revenues.

Sales of our products to large service providers can involve a lengthy sales cycle, which may impact the timing of our revenues and result in us expending significant resources without making any sales.

Our sales cycles to large service providers, including carriers, mobile operators and cable operators, are generally lengthy because these end-customers consider our products to be critical equipment and undertake significant testing to assess the performance of our products within their networks. Furthermore, many of our product and service arrangements with our customers provide that the final acceptance of a product or service may be specified by the customer. In such instances, we do not recognize the revenue until all acceptance criteria have been met. As a result, we often invest significant time from initial contact with a large service provider until it decides to incorporate our products into its network, and we may not be able to recognize the revenue from a customer until all acceptance criteria have been satisfied. We may also expend significant resources in attempting to persuade large service providers to incorporate our products into their networks without success. Even after deciding to purchase our products, the initial network deployment of our products by a large service provider may last up to one year and in certain exceptional instances up to one and a half years. If a competitor succeeds in convincing a large service provider to adopt that competitor’s product, it may be difficult for us to displace the competitor because of the cost, time, effort and perceived risk to network stability involved in changing solutions. As a result, we may incur significant expenses without generating any sales, which could adversely affect our profitability.

The complexity and scope of the solutions and services we provide to larger service providers are increasing, and such larger projects entail greater operational risk and an increased chance of failure.

The complexity and scope of the solutions and services we provide to larger service providers are increasing. The larger and more complex such projects are, the greater the operational risks associated with them. These risks include, but are not limited to, the failure to meet high customization requirements of service providers, the failure to fully integrate our products into the service provider’s network or with third-party products, our dependence on subcontractors and partners and on effective cooperation with third-party vendors for the successful and timely completion of such projects. If we encounter any of these risks, we may incur higher costs in order to complete the project and may be subject to contractual penalties resulting in lower profitability. In addition, the project may demand more of our management’s time than was originally planned, and our reputation may be adversely impacted.

We depend on third parties to market, sell, and install our products and to provide initial technical support for our products for a material portion of our business.

We depend on third-party channel partners, such as distributors, resellers, original equipment manufacturers, or OEMs, and system integrators, to market and sell a material portion of our products to end-customers. In 2017, approximately 50% of our revenues were derived from channel partners. Our channel partners are also responsible for installing our products and providing initial customer support for them. As a result, we depend on the ability of our channel partners to successfully market and sell our products to these end-customers. We can give no assurance that our channel partners will market our products effectively, receive and fulfill customer orders for our products on a timely basis or continue to devote the resources necessary to provide us with effective sales, marketing and technical support. In addition, any failure by our channel partners to provide adequate initial support to end-customers could result in customer dissatisfaction with us or our products, which could result in a loss of customers, harm our reputation and delay or limit market acceptance of our products. Our products are complex and it takes time for a new channel partner to gain experience in the operation and installation of these products. Therefore, it may take a period of time before a new channel partner can successfully market, sell and support our products if an existing channel partner ceases to sell our products. Additionally, our agreements with channel partners are generally not exclusive and our channel partners may market and sell products that compete with our products. Our agreements with our distributors and resellers are usually for an initial one-year term and following the expiration of this term, can be terminated by either party. We can give no assurance that these agreements will remain in effect. If we are unable to maintain our relationships with existing channel partners and to develop relationships with new channel partners in key markets our profitability and results of operations may be materially adversely affected.

We are subject to certain regulatory regimes that may affect the way that we conduct business internationally, and our failure to comply with applicable laws and regulations could materially adversely affect our reputation and result in penalties and increased costs.

We are subject to a complex system of laws and regulations related to international trade, including economic sanctions and export control laws and regulations. We also depend on our distributors and agents outside of Israel for compliance and adherence to local laws and regulations in the markets in which they operate. It is our policy not to make direct or indirect prohibited sales of our products, including into countries sanctioned under laws to which we are subject, and to contractually limit the territories into which our channel partners may sell our products. Nevertheless, several years ago one of our channel partners sold certain of our products (designed for the enterprise market) outside of its contractually designated territory, including into a sanctioned country, and we subsequently determined that our contract management protocol for authorizing channel partner sales was not adequately followed in that instance.

Significant political or regulatory developments in the jurisdictions in which we sell our products, such as those stemming from the recent change in the presidential administration in the U.S. or the U.K.’s “Brexit” referendum, are difficult to predict and may have a material adverse effect on us. For example, in the United States, the presidential administration has expressed support for greater restrictions on free trade and increase tariffs on goods imported into the United States. Changes in U.S. political, regulatory and economic conditions or in its policies governing international trade and foreign manufacturing and investment in the U.S. could adversely affect our sales in the U.S.

In the United Kingdom, following the vote to approve an exit from the E.U., commonly referred to as “Brexit,” the government officially triggered the process to formally initiate negotiations for the terms of separation from the E.U. The U.K. and the E.U. are expected to reach an agreement by 2019; however, the exact terms and timing of such exit remain unclear. The withdrawal of the U.K from the E.U. could potentially disrupt the free movement of goods, services and people between the U.K. and the E.U., undermine bilateral cooperation in key geographic areas and significantly disrupt trade between the U.K. and the E.U. or other nations as the U.K. pursues independent trade relations. Because this is an unprecedented event, it is unclear what long-term economic, financial, trade and legal implications Brexit would have and how it would affect the regulation applicable to our business globally and in the region. The impact on us will depend, in part, on the outcome of tariff, trade, regulatory and other negotiations. Brexit could also lead to legal uncertainty and potentially divergent national laws and regulations as the U.K. determines which E.U. laws to replace or replicate. In addition, Brexit may lead other E.U. member countries to consider referendums regarding their European Union membership. Any of these developments, along with any political, economic and regulatory changes that may occur, could cause political and economic uncertainty in Europe and internationally and could adversely affect our sales in Europe.

We are also subject to the U.S. Foreign Corrupt Practices Act and may be subject to similar worldwide anti-bribery laws that generally prohibit companies and their intermediaries from making improper payments to government officials for the purpose of obtaining or retaining business. Some of the countries in which we operate have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. Despite our compliance and training programs, we cannot be certain that our procedures will be sufficient to ensure consistent compliance with all applicable international trade and anti-corruption laws, or that our employees or channel partners will strictly follow all policies and requirements to which we subject them. Any alleged or actual violations of these laws may subject us to government scrutiny, investigation, debarment, and civil and criminal penalties, which may have an adverse effect on our results of operations, financial condition and reputation.

We depend on our network intelligence solutions for the substantial majority of our revenues.

In the past few years, we have increased sales of our security products. However, sales of our network intelligence solutions, which provide service providers with visibility and control of their networks, continue to account for a major portion of our revenues, and accounted for 71% of our total revenue in 2017. We expect that the network intelligence solutions will continue to account for a considerable portion of our revenues in the immediate future. If we are unable to increase these sales, or compensate for them by sales of security products, our business will suffer. In addition, service providers may choose embedded or integrated solutions using routers and switches from larger networking vendors over a standalone solution that we offer. Any factor adversely affecting our ability to sell, or the pricing of or demand for, our network intelligence solutions would severely harm our ability to generate revenues and could have a material adverse effect on our business.

We integrate into or bundle various third-party solutions with our products and may integrate or offer additional third-party solutions in the future. If we lose the right to use such solutions, our sales could be disrupted and we would have to spend additional capital to replace such components.

We integrate various third-party solutions into our products and offer third-party solutions bundled with our products. We may integrate or offer additional third-party solutions in the future. Sales of our products could be disrupted if such third-party solutions were either no longer available to us or no longer offered to us on commercially reasonable terms. In either case, we would be required to spend additional capital to either source alternative third-party solutions, redesign our products to function with alternate third-party solutions or develop substitute components ourselves. As a result, our sales may be delayed and/or adversely affected and we might be forced to limit the features available in our current or future product offerings, which could have a material adverse effect on our business.

Our products are highly technical and any undetected software or hardware errors in our products could have a material adverse effect on our operating results.

Our products are complex and are incorporated into broadband networks, which are a major source of revenue for service providers and support critical applications for subscribers and enterprises. Due to the highly technical nature of our products and variations among customers’ network environments, we may not detect product defects until our products have been fully deployed in our customers’ networks. Regardless of whether warranty coverage exists for a product, we may be required to dedicate significant technical resources to repair any defects. If we encounter significant errors, we could experience, among other things, loss of major customers, cancellation of orders, increased costs, delay in recognizing revenues and damage to our reputation. We could also face claims for product liability, tort or breach of warranty. Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention. In addition, if our business liability insurance is inadequate or future coverage is unavailable on acceptable terms or at all, our financial condition could be harmed.

Demand for our DPI technology enabled products depends, in part, on the rate of adoption of bandwidth-intensive broadband applications, and the impact multiple applications may have on network speed.

Our DPI technology enabled products are used by service providers and enterprises to monitor and manage bandwidth-intensive applications that cause congestion in broadband networks and impact the quality of experience for users. Demand for our products is driven particularly by growth in applications, which are highly sensitive to network delays and therefore require efficient network management. If the rapid growth in the adoption of such applications does not continue, the demand for our products may be adversely impacted.

Demand for our security products depends, in part, on continued evolution of on-line threats as well as on operators’ interest in providing security services to their end customers.

Our security products are used by service providers to offer security services to their end customers, comprising both of business enterprises as well as individual end customers. The demand for these services depends highly on continued evolution and increase of online threats. In the event that such threats decrease, that end customers are unwilling to incur the costs of security services and/or that ISPs do not continue to pursue security services to their end customers as a revenue source, demand for our security products may be materially adversely impacted.

We currently depend on a single subcontractor to manufacture and provide hardware and warranty support for our Service Gateway Tera platform. If this subcontractor experiences delays, disruptions, quality control problems or a loss in capacity, it could materially and adversely affect our operating results

We currently depend on a single subcontractor, Flex (Israel) Ltd. (previously Flextronics (Israel) Ltd.), a subsidiary of Flex (previously Flextronics), a global electronics manufacturing services company, to manufacture, assemble, test, package and provide hardware warranty support for our Service Gateway Tera platform. In addition, our agreement with Flex (Israel) requires it to procure and store key components for our products at its facilities. If Flex (Israel) experiences delays, disruptions or quality control problems in manufacturing our products, or if we fail to effectively manage our relationship with Flex (Israel), product shipments may be delayed and our ability to deliver products to customers could be materially and adversely affected. Flex (Israel) may terminate our agreement at any time during the term upon prior notice. We expect that it would take approximately six months to transition the manufacturing of our products to an alternate manufacturer and our inventory of completed products may not be sufficient for us to continue delivering products to our customers on a timely basis during any such transition period. Therefore, the loss of Flex (Israel) could adversely affect our sales and operating results and harm our reputation.

Certain hardware and software components for our products come from single or limited sources and we could lose sales if these sources fail to satisfy our supply requirements or if our customers refuse to implement components from certain sources.

We obtain certain hardware components used in our products from single or limited sources.

Although the abovementioned hardware components are off-the-shelf items, because our systems have been designed to incorporate these specific hardware components, any change to these components due to an interruption in supply or our inability to obtain such components on a timely basis, may require engineering changes to our products before substitute hardware components could be incorporated. Such changes could be costly and result in lost sales particularly to our traffic management systems. The agreements with our suppliers do not contain any minimum supply commitments. If we or our contract manufacturer fail to obtain components in sufficient quantities when required, our business could be harmed.

We obtain certain software components of our security products from a few limited sources, depending primarily on our customers' preferences. In the event that we are no longer able to source such software components from a particular source, and our customers refuse to implement components from our alternative sources, we may be required to identify an alternative source from which we do not currently acquire such software or develop such software ourselves. This may result in disputes with our customers and/or cancellation or delay of orders, which may materially adversely affect our business.

Our suppliers also sell products to our competitors and may enter into exclusive arrangements with our competitors, stop selling their products or components to us at commercially reasonable prices or refuse to sell their products or components to us at any price. Our inability to obtain sufficient quantities of single-source or limited-sourced components or to develop alternative sources for components or products would harm our ability to maintain and expand our business.

We may expand our business or enhance our technology through acquisitions that could result in diversion of resources and extra expenses. This could disrupt our business and adversely affect our financial condition.

Part of our strategy is to selectively pursue partnerships and acquisitions. We have acquired a number of companies in recent years, including most recently, the acquisition of all of the outstanding shares of Netonomy Ltd., a Tel-Aviv based developer of software-based cyber security for the connected home. The negotiation of acquisitions, investments or joint ventures, as well as the integration of acquired or jointly developed businesses or technologies, could divert our management’s time and resources. Acquired businesses, technologies or joint ventures may not be successfully integrated with our products and operations and we may not realize the intended benefits of these acquisitions. We may also incur future losses from any acquisition, investment or joint venture. In addition, acquisitions could result in:

substantial cash expenditures;

potentially dilutive issuances of equity securities;

the incurrence of debt and contingent liabilities;

a decrease in our profit margins; and

amortization of intangibles and potential impairment of goodwill.

If acquisitions disrupt our operations or result in significant expenditures or liabilities, our business, operating results or financial conditions may suffer.

If we are unable to successfully protect the intellectual property embodied in our technology, our business could be materially adversely affected.

Know-how relating to networking protocols, building carrier-grade systems, identifying applications and developing and maintaining security products is an important aspect of our intellectual property. It is our practice to have our employees sign appropriate non-compete agreements when permitted under applicable law. These agreements prohibit our employees who cease working for us from competing directly with us or working for our competitors for a limited period of time. The enforceability of non-compete clauses in certain jurisdictions in which we operate may be limited. Under the current laws of some jurisdictions in which we operate, we may be unable to enforce these agreements and it may thereby be difficult for us to restrict our competitors from gaining the expertise our former employees gained while working for us.

Further, to protect our know-how, we customarily require our employees, distributors, resellers, software testers and contractors to execute confidentiality agreements or agree to confidentiality undertakings when their relationship with us begins. Typically, our employment contracts also include clauses regarding assignment of intellectual property rights for all inventions developed by employees and non-disclosure of all confidential information. We cannot provide any assurance that the terms of these agreements are being observed and will be observed in the future. Because our product designs and software are stored electronically and thus are highly portable, we attempt to reduce the portability of our designs and software by physically protecting our servers through the use of closed networks, which prevent external access to our servers. We cannot be certain, however, that such protection will adequately deter individuals or groups from wrongfully accessing our technology. Monitoring unauthorized use of intellectual property is difficult and some foreign laws do not protect proprietary rights to the same extent as the laws of the United States. We cannot be certain that the steps we have taken to protect our proprietary information will be sufficient. In addition, to protect our intellectual property, we may become involved in litigation, which could result in substantial expenses, divert the attention of management, or materially disrupt our business, all of which could adversely affect our revenue, financial condition and results of operations.

As of December 31, 2017, we had a patent portfolio consisting of 17 issued U.S. patents. While we plan to protect our intellectual property with, among other things, patent protection, there can be no assurance that:

current or future U.S. or foreign patents applications will be approved;

our issued patents will protect our intellectual property and not be held invalid or unenforceable if challenged by third-parties;

we will succeed in protecting our technology adequately in all key jurisdictions in which we or our competitors operate;

the patents of others will not have an adverse effect on our ability to do business; or

others will not independently develop similar or competing products or methods or design around any patents that may be issued to us.

Any failure to obtain patents, inability to obtain patents with claims of a scope necessary to cover our technology or the invalidation of our patents may weaken our competitive position and may adversely affect our revenues.

We may be subject to claims of intellectual property infringement by third parties that, regardless of merit, could result in litigation and our business, operating results or financial condition could be materially adversely affected.

There can be no assurance that we will not receive communications from third parties asserting that our products, and other intellectual property infringe, or may infringe their proprietary rights. We are not currently subject to any proceedings for infringement of patents or other intellectual property rights and are not aware of any parties that intend to pursue such claims against us. Any such claim, regardless of merit, could result in litigation, which could result in substantial expenses, divert the attention of management, cause significant delays and materially disrupt the conduct of our business. As a consequence of such claims, we could be required to pay substantial damage awards, develop non-infringing technology, enter into royalty-bearing licensing agreements, stop selling our products or re-brand our products. If it appears necessary, we may seek to license intellectual property that we are alleged to infringe. Such licensing agreements may not be available on terms acceptable to us or at all. Litigation is inherently uncertain and any adverse decision could result in a loss of our proprietary rights, subject us to significant liabilities, require us to seek licenses from others and otherwise negatively affect our business. In the event of a successful claim of infringement against us and our failure or inability to develop non-infringing technology or license the infringed or similar technology, our business, operating results or financial condition could be materially adversely affected.

We use certain “open source” software tools that may be subject to intellectual property infringement claims, the assertion of which could impair our product development plans, interfere with our ability to support our clients or require us to pay licensing fees

Certain of our products contain open source code, and we may use more open source code in the future. Open source code is the type of code that is covered by a license agreement that permits the user to copy, modify and distribute the software without cost, provided that users and modifiers abide by certain licensing requirements. The original developers of the open source code provide no warranties on such code. As a result of our use of open source software, we could be subject to suits by parties claiming ownership of what we believe to be open source code, and we may incur expenses in defending claims that we did not abide by the open source code license. If we are not successful in defending against such claims, we may be subject to monetary damages or be required to remove the open source code from our products. Such events could disrupt our operations and the sales of our products, which would negatively impact our revenues and cash flow. In addition, under certain conditions, the use of open source code to create derivative code may obligate us to make the resulting derivative code available to others at no cost. If we are required to publicly disclose the source code for such derivative products or to license our derivative products that use an open source license, our previously proprietary software products would be available to others, including our customers and competitors without charge. While we endeavor to ensure that no open source software is used in a way which may require us to disclose the source code to our related product, such use could inadvertently occur. If we were required to make our software source code freely available, our business could be seriously harmed. The use of such open source code may ultimately subject some of our products to unintended conditions so that we are required to take remedial action that may divert resources away from our development efforts.

Unfavorable or unstable economic conditions in the markets in which we operate could have a material adverse effect on our business, financial condition or operating results.

In recent years, economies worldwide have demonstrated instability. Negative economic conditions in the global economy or certain regions such as the European Market, from which we derived 49% of our revenues in 2017, could cause a decrease in spending on the types of products and services that we offer.

Additionally, if the worldwide economy remains unstable or further deteriorates, enterprises, telecommunication carriers and service providers in affected regions may significantly reduce or postpone capital investments, which could result in reductions in sales of our products or services, longer sales cycles, slower adoption of new technologies and increased price competition in such regions. Such circumstances would have a material adverse effect on our results of operations and cash flows.

Further, because a substantial portion of our operating expenses consists of salaries, we may not be able to reduce our operating expenses in line with any reduction in revenues and, therefore, may not be able to continue to generate increased revenues and manage our costs to maintain profitability.

Our international operations expose us to the risk of fluctuations in currency exchange rates.

Our revenues are generated primarily in U.S. dollars and a major portion of our expenses are denominated in U.S. dollars. As a result, we consider the U.S. dollar to be our functional currency. A significant portion of our revenue is also generated in Euros. Other significant portions of our expenses are denominated in Israeli shekel (ILS) and, to a lesser extent, in Euros and other currencies. Our ILS-denominated expenses consist principally of salaries and related personnel expenses. We anticipate that a material portion of our expenses will continue to be denominated in ILS. In the past years, we have experienced material fluctuation between the ILS and the U.S. dollar and we anticipate that the ILS will continue to fluctuate against the U.S dollar in the future. In 2017, the ILS appreciated by approximately 10.9% against the U.S. dollar and in 2016 the ILS appreciated by approximately 1.5% against the U.S. dollar. In 2017, the EUR appreciated by approximately 13.9% against the U.S. dollar, and in 2016 the EUR depreciated by approximately 3.3% against the U.S. dollar. The weakening of the U.S. dollar against the ILS expose us to negative impact on our results of operations. Moreover, if the U.S. dollar will strengthen against the EUR, our results of operations generated by revenue in the EUR may be negatively impacted.

We use derivative financial instruments, such as foreign exchange forward contracts, to mitigate the risk of changes in foreign exchange rates on balance sheet accounts and forecast cash flows. We may not purchase derivative instruments adequately to insulate ourselves from foreign currency exchange risks. The volatility in the foreign currency markets may make hedging our foreign currency exposures challenging. In addition, because a portion of our revenue is not earned in U.S. dollars, fluctuations in exchange rates between the U.S. dollar and the currencies in which such revenue is earned may have a material adverse effect on our results of operations and financial condition. Additionally, our efforts to effectively price products in U.S. dollars may have disadvantages as they may affect demand for our products if the local currency strengthens relative to the U.S. dollar. We could be adversely affected when the U.S. dollar strengthens relative to the local currency between the time of a sale and the time we receive payment, which would be collected in the devalued local currency. Accordingly, if there is an adverse movement in one or more exchange rates, we might suffer significant losses and our results of operations may otherwise be adversely affected. Uncertainty in global market conditions has resulted in and may continue to cause significant volatility in foreign currency exchange rates which could increase these risks. As our international operations expand, our exposure to these risks also increases.

Disruption to our IT systems could adversely affect our reputation and have a material adverse effect on our business and results of operations.

Risks to cybersecurity and privacy, including the activities of criminal hackers, hacktivists, state-sponsored intrusions, industrial espionage, employee malfeasance and human or technological error are constantly evolving. Computer hackers’ and others routinely attempt to breach the security of high profile companies, governmental agencies, technology products, services and systems.

Our IT systems contain personal, financial and other information that is entrusted to us by our customers and employees as well as financial, proprietary and other confidential information related to our business, and we rely on said systems to manage our business, operations and research and development. If these IT systems are compromised as a result of cyber attacks or cyber related incidents, it could result in the loss or misappropriation of sensitive data or other disruption to our operations. Although we have a comprehensive cybersecurity program designed to protect and preserve the integrity of our information technology systems, we have experienced and expect to continue to experience actual or attempted cyber-attacks of our IT systems or networks (such as limited fishing and malware activities identified by us in the past, which were mitigated). Although none of these actual or attempted cyber-attacks has had a material effect on our operations or financial condition, we cannot guarantee that any such incidents would not materially harm our business in the future.

Despite our investments in risk prevention and contingencies, data protection, prevention of intrusions, access control systems and other security measures, we can provide no assurance that our current IT systems are fully protected against third-party intrusions, viruses, hacker attacks, information or data theft or other similar threats. Any such security breach, whether actual or alleged, could result in system disruptions or shutdowns and/or destruction, alteration, theft or unauthorized disclosure of confidential information. Even when a security breach is detected, the full extent of the breach may not be determined for some time. An increasing number of companies have disclosed security breaches of their IT systems and networks, some of which have involved sophisticated and highly targeted attacks. We believe such incidents are likely to continue, and we are unable to predict the direct or indirect impact of these future attacks on our business.

Furthermore, there has been heightened legislative and regulatory focus on data security in the U.S., Europe and other jurisdictions, including requirements for varying levels of customer notification in the event of a data breach. We are already subject to strict data privacy laws in the European Union and other jurisdictions in which we operate, governing the collection, transmission, storage and use of employee data and personally identifying information. In addition, the GDPR, coming into effect in Europe in May 2018, creates a range of new compliance obligations, and extends the scope of the E.U. data protection law. Such regulations may increase our compliance and administrative burden significantly and may require us to invest resources and management attention in order to update our IT systems to meet the new requirements. Any breach of our information security can result in adverse publicity, a loss of customer confidence, reduced sales and profits, and criminal penalties or civil liabilities, any of which could materially adversely affect our business, operating results and financial condition.

Our actual financial results may differ materially from any guidance we may publish from time to time.

We may, from time to time, voluntarily publish guidance regarding our future performance that represents our management’s estimates as of the date of relevant release. Any such guidance is based upon a number of assumptions and estimates that, while presented with numerical specificity, is inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control and are based upon specific assumptions with respect to future business decisions, some of which will change. The principal reason that we may release this data is to provide a basis for our management to discuss our business outlook with analysts and investors. We do not accept any responsibility for any projections or reports published by any such persons. Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions of the guidance furnished by us will not materialize or will vary significantly from actual results. Further, our sales during any given quarter tend to be unevenly distributed as individual orders tend to close in greater numbers immediately prior to the relevant quarter end and further. Our revenues from individual customers may also fluctuate from time to time based on the timing and the terms under which further orders are received and the duration of the delivery and implementation of such orders. Therefore, if our projected sales do not close before the end of the relevant quarter, our actual results may be inconsistent with our published guidance. Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release. Actual results will vary from the guidance and the variations may be material. Investors should also recognize that the reliability of any forecasted financial data diminishes the farther in the future that the data is forecast. In light of the foregoing, investors are urged to consider any guidance we may publish in context and not to place undue reliance on it.

Our business may be materially affected by changes to fiscal and tax policies. Potentially negative or unexpected tax consequences of these policies, or the uncertainty surrounding their potential effects, could adversely affect our results of operations and share price.

As we operate in the global market, we are subject to tax in Israel and various jurisdictions in which we conduct our business. Our tax expenses include the impact of tax exposures in certain jurisdictions, and may also be affected by adverse changes in the underlying profitability and financial outlook of our operations or changes in tax law, including international tax treaties, or guidelines such as the BEPS project (Base Erosion and Profit Shifting), which could lead to changes in our valuation allowances against deferred tax assets on our consolidated balance sheets. Furthermore, we are subject to tax audits by governmental authorities, primarily in Israel and the United States. If we experience unfavorable results from one or more such tax audits, there could be an adverse effect on our tax rate and therefore on our net income.

Our results of operations may be affected by changes in tax laws, tax rates or double tax treaties. For example, in the United States, H.R. 1, originally known as the 2017 Tax Cuts and Jobs Act (the “TCJA”) made significant changes to the U.S. Internal Revenue Code, including a reduction in the federal income corporate tax rate from 35% to 21% and limitations on certain corporate deductions and credits. In addition, the TCJA requires complex computations to be performed that were not previously required in U.S. tax law, significant judgments to be made in interpretation of the provisions of the TCJA and significant estimates in calculations, and the preparation and analysis of information not previously relevant or regularly produced. The U.S. Treasury Department, the IRS, and other standard-setting bodies could interpret or issue guidance on how provisions of the TCJA will be applied or otherwise administered that is different from our interpretation. Finally, foreign governments may enact tax laws in response to the TCJA that could result in further changes to global taxation and materially affect our financial position and results of operations. While we have provided the effect of the TCJA in our Consolidated Financial Statements as included in note 13 to our financial statements included elsewhere in this report, the application of accounting guidance for various items and the ultimate impact of the TCJA on our business are currently uncertain.

Risks Related to Our Ordinary Shares

The share price of our ordinary shares has been and may continue to be volatile.

Our quarterly financial performance is likely to vary in the future, and may not meet our expectations or the expectations of analysts or investors, which may lead to additional volatility in our share price. The market price of our ordinary shares may be volatile and could fluctuate substantially due to many factors, including, but not limited to:

announcements or introductions of technological innovations, new products, product enhancements or pricing policies by us or our competitors;

winning or losing contracts with service providers;

disputes or other developments with respect to our or our competitors’ intellectual property rights;

announcements of strategic partnerships, joint ventures, acquisitions or other agreements by us or our competitors;

recruitment or departure of key personnel;

regulatory developments in the markets in which we sell our products;

our future repurchases, if any, of our ordinary shares pursuant to our current share repurchase program and/or any other share repurchase program which may be approved in the future;

our sale of ordinary shares or other securities;

changes in the estimation of the future size and growth of our markets; or

market conditions in our industry, the industries of our customers and the economy as a whole.

Share price fluctuations may be exaggerated if the trading volume of our ordinary shares is too low. The lack of a trading market may result in the loss of research coverage by securities analysts. Moreover, we can provide no assurance that any securities analysts will initiate or maintain research coverage of our company and our ordinary shares. If our future quarterly operating results are below the expectations of securities analysts or investors, the price of our ordinary shares would likely decline. Securities class action litigation has often been brought against companies following periods of volatility.

Our shareholders do not have the same protections afforded to shareholders of a U.S. company because we have elected to use certain exemptions available to foreign private issuers from certain NASDAQ corporate governance requirements.

As a foreign private issuer, we are permitted under NASDAQ Rule 5615(a)(3) to follow Israeli corporate governance practices instead of the NASDAQ Stock Market requirements that apply to U.S. companies. As a condition to following Israeli corporate governance practices, we must disclose which requirements we are not following and describe the equivalent Israeli law requirement. We must also provide NASDAQ with a letter from our Israeli outside counsel, certifying that our corporate governance practices are not prohibited by Israeli law. As a result of these exemptions, our shareholders do not have the same protections as are afforded to shareholders of a U.S. company. We currently follow Israeli home country practices with regard to the quorum requirement for shareholder meetings and shareholder approval of equity compensation plans requirements. As permitted under the Israeli Companies Law, 5759-1999, or the Companies Law, our articles of association provide that the quorum for any meeting of shareholders shall be the presence of at least two shareholders present in person or by proxy who hold at least 25% of the voting power of our shares instead of 33 1/3% of our issued share capital (as prescribed by NASDAQ's rules). We do not seek shareholder approval for equity compensation plans in accordance with the requirements of the Companies Law, which does not fully reflect the requirements of Rule 5635(c).

In the future, we may also choose to follow Israeli corporate governance practices instead of NASDAQ requirements with regard to, among other things, the composition of our board of directors, compensation of officers, director nomination procedures and quorum requirements at shareholders’ meetings. In addition, we may choose to follow Israeli corporate governance practice instead of NASDAQ requirements to obtain shareholder approval for certain dilutive events (such as for issuances that will result in a change of control of the company, certain transactions other than a public offering involving issuances of a 20% or more interest in the company and certain acquisitions of the stock or assets of another company). Accordingly, our shareholders may not be afforded the same protection as provided under NASDAQ corporate governance rules. Following our home country governance practices, as opposed to the requirements that would otherwise apply to a U.S. company listed on the Nasdaq Global Select Market, may provide less protection than is accorded to investors of domestic issuers. See “ITEM 16G: Corporate Governance”.

As a foreign private issuer, we are not subject to the provisions of Regulation FD or U.S. proxy rules and are exempt from filing certain Exchange Act reports.

As a foreign private issuer, we are exempt from the rules and regulations under the Exchange Act related to the furnishing and content of proxy statements, and our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we are not required under the Exchange Act to file annual and current reports and financial statements with the SEC as frequently or as promptly as U.S. domestic companies whose securities are registered under the Exchange Act, we are permitted to disclose limited compensation information for our executive officers on an individual basis and we are generally exempt from filing quarterly reports with the SEC under the Exchange Act. Moreover, we are not required to comply with Regulation FD, which restricts the selective disclosure of material nonpublic information to, among others, broker-dealers and holders of a company’s securities under circumstances in which it is reasonably foreseeable that the holder will trade in the company’s securities on the basis of the information. These exemptions and leniencies reduce the frequency and scope of information and protections to which you may otherwise have been eligible in relation to a U.S. domestic issuer.

We would lose our foreign private issuer status if (a) a majority of our outstanding voting securities were either directly or indirectly owned of record by residents of the United States and (b)(i) a majority of our executive officers or directors were United States citizens or residents, (ii) more than 50% of our assets were located in the United States or (iii) our business were administered principally in the United States. Our loss of foreign private issuer status would make U.S. regulatory provisions mandatory. The regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic issuer may be significantly higher. If we are not a foreign private issuer, we will be required to file periodic reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive than the forms available to a foreign private issuer. We would also be required to follow U.S. proxy disclosure requirements, including the requirement to disclose, under U.S. law, more detailed information about the compensation of our senior executive officers on an individual basis. We may also be required to modify certain of our policies to comply with accepted governance practices associated with U.S. domestic issuers. Such conversion and modifications will involve additional costs. In addition, we would lose our ability to rely upon exemptions from certain NASDAQ corporate governance requirements that are available to foreign private issuers.

Our U.S. shareholders may suffer adverse tax consequences if we are characterized as a passive foreign investment company.

Generally, if for any taxable year 75% or more of our gross income is passive income, or the average percentage of our assets which produce passive income or which are held for the production of passive income (“passive assets”) is at least 50% of our total net assets, we would be characterized as a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes for such taxable year. Publicly traded corporations must determine the percentage of assets on the basis of the value of their assets. No definitive guidance has been issued by the U.S. government concerning how to value the assets of a foreign public company for PFIC testing purposes. It can be inferred from the legislative history that the fair market value of the total assets of a publicly traded foreign corporation can be more easily measured, and is therefore likely to be less burdensome to taxpayers, by applying the “market capitalization” method. Under the market capitalization method, the total asset value of a company would be considered to equal the aggregate fair market value of its outstanding stock (i.e., its market capitalization) plus its outstanding liabilities, as of a relevant testing date. However, the legislative history did not specify the circumstances under which it would be appropriate to use the “market capitalization” method, or that such method was an exclusive means for valuing the total assets of a publicly traded corporation. Accordingly, if the market capitalization approach is found to be insufficient in the context of the facts and circumstances of a particular case, other reasonable valuation methods may be employed to determine the fair market value of a corporation’s assets. In certain circumstances, including extremely volatile market conditions, it may be appropriate to apply alternative valuation methods, to more accurately determine the fair market value of our assets, such as a valuation of the assets by an independent qualified expert. Given the volatility of the capital markets in recent years, we have obtained an independent valuation of our company for the 2017 tax year, as well as an opinion from a U.S. tax advisor that, applying the results of the independent valuation of our company which employed an approach other than the market capitalization approach, and which provided the reasoning underlying the use of such approach, we should not be a PFIC for the 2017 taxable year. We considered such valuation in determining the value of our total assets and we also considered the above-referenced opinion. On that basis, we believe that we were not a PFIC for the 2017 tax year; however there can be no certainty that the IRS will not challenge such a position and determine that based on the IRS’s interpretation of the asset test, we were a PFIC for the 2017 tax year. Thus, there can be no assurance that we will not be considered a PFIC for 2017 or for any other taxable year. U.S. Holders should consult their own tax advisors concerning the implication of the PFIC rules in his, her or its particular circumstances. See “ITEM 10: Taxation–United States Federal Income Taxation–Passive Foreign Investment Company Considerations.”

If we were characterized as a passive foreign investment company, a U.S. Holder (as defined under “ITEM 10: Additional Information–Taxation–United States Federal Income Taxation–Passive Foreign Investment Company Considerations”) could avoid certain adverse passive foreign investment company consequences by making a qualified electing fund election to be taxed currently on its proportionate share of the passive foreign investment company’s ordinary income and net capital gains. However, we do not intend to comply with the necessary accounting and record keeping requirements that would allow a U.S. Holder to make a qualified electing fund election with respect to the Company. See “ITEM 10: Additional Information–Taxation–United States Federal Income Taxation–Passive Foreign Investment Company Considerations.”

Certain U.S. holders of our ordinary shares may suffer adverse tax consequences if we or any of our non-U.S. subsidiaries are characterized as a “controlled foreign corporation”, or a CFC, under Section 957(a) of the Internal Revenue Code of 1986, as amended (the “Code”).

A non-U.S. corporation is considered a CFC if more than 50 percent of (1) the total combined voting power of all classes of stock of such corporation entitled to vote, or (2) the total value of the stock of such corporation, is owned, or is considered as owned by applying certain constructive ownership rules, by United States shareholders who each own stock representing 10% or more of the vote or, for the taxable year of a non-U.S. corporation beginning after December 31, 2017 and for taxable years of shareholders with or within which such taxable years of such non-U.S. corporation ends, 10% or more of the value on any day during the taxable year of such non-U.S. corporation (“10% U.S. Shareholder”). Generally, 10% U.S. Shareholders of a CFC are required to include currently in gross income such 10% U.S. Shareholder’s share of the CFC’s “Subpart F income”, a portion of the CFC’s earnings to the extent the CFC holds certain U.S. property, and certain other new items under the TCJA. Such 10% U.S. Shareholders are subject to current U.S. federal income tax with respect to such items, even if the CFC has not made an actual distribution to such shareholders. “Subpart F income” includes, among other things, certain passive income (such as income from dividends, interests, royalties, rents and annuities or gain from the sale of property that produces such types of income) and certain sales and services income arising in connection with transactions between the CFC and a person related to the CFC.

Certain changes to the CFC constructive ownership rules introduced by the TCJA may cause one or more of our non-U.S. subsidiaries to be treated as CFCs and may impact our CFC status, thus affecting holders of our ordinary shares that are 10% United States shareholders. For 10% U.S. Shareholders, this may result in negative U.S. federal income tax consequences, such as current U.S. taxation of Subpart F income and of any such shareholder’s share of our accumulated non-U.S. earnings and profits (regardless of whether we make any distributions), taxation of amounts treated as global intangible low-taxed income under Section 951A of the Code with respect to such shareholder, and being subject to certain reporting requirements with the U.S. Internal Revenue Service. Current or prospective 10% U.S. Shareholders should consult their own tax advisors regarding the U.S. tax consequences of acquiring, owning, or disposing our ordinary shares and the impact of the TCJA, especially the changes to the rules relating to CFCs.

If the price of our ordinary shares declines, we may be more vulnerable to an unsolicited or hostile acquisition bid.

We do not have a controlling shareholder. Notwithstanding provisions of our articles of association and Israeli law, a decline in the price of our ordinary shares may result in us becoming subject to an unsolicited or hostile acquisition bid. In the event that such a bid is publicly disclosed, it may result in increased speculation regarding our company and volatility in our share price even if our board of directors decides not to pursue a transaction. If our board of directors does pursue a transaction, there can be no assurance that it will be consummated successfully or that the price paid will represent a premium above the original price paid for our shares by all of our shareholders.

Risks Relating to our Location in Israel

Conditions in Israel could adversely affect our business.

We are incorporated under Israeli law and our principal offices, research and development division and manufacturing facilities are located in Israel. Accordingly, political, economic and military conditions in Israel directly affect our business. Since the State of Israel was established in 1948, a number of armed conflicts have occurred between Israel and its Arab neighbors. Although Israel has entered into various agreements with Egypt, Jordan and the Palestinian Authority, there has been an increase in unrest and terrorist activity, which began in September 2000 and continued with varying levels of severity into 2017. In recent years, these have included, among others, hostilities between Israel and Hezbollah in Lebanon and Hamas in the Gaza strip, both of which resulted in rockets being fired into Israel, causing casualties and significant disruption of economic activities. Outside of periods of armed conflict, Israel has also historically experienced terrorist activity and unrest, including for instance, recent unrest due to the United States’ announcement to relocate its embassy from Tel Aviv to Jerusalem. Any armed conflicts, terrorist activities or political instability in the region may affect a significant portion of our work force, which is located in Israel, and may limit materially our ability to obtain raw materials from affected countries or sell our products to companies in these countries. Any hostilities involving Israel or the interruption or curtailment of trade between Israel and its present trading partners, or significant downturn in the economic or financial condition of Israel, could adversely affect our operations and product development and manufacturing, cause our revenues to decrease and adversely affect the share price of publicly traded companies having operations in Israel, such as us.

Our operations may be disrupted by the obligations of personnel to perform military service.

As of December 31, 2017, we employed 477 people, of whom 260 were based in Israel. Some of our employees in Israel are obligated to perform annual military reserve duty in the Israel Defense Forces, depending on their age and position in the army. Additionally, they may be called to active reserve duty at any time under emergency circumstances for extended periods of time. Our operations could be disrupted by the absence of one or more of our executive officers or key employees for a significant period due to military service and any significant disruption in our operations could harm our business. The full impact on our workforce or business if some of our executive officers and employees are called upon to perform military service, especially in times of national emergency, is difficult to predict. Additionally, the absence of a significant number of employees at our manufacturing subcontractor, Flex, as a result of military service obligations may disrupt their operations and could have a material adverse effect on our ability to timely deliver products to customers may be materially adversely affected.

The tax benefits that are available to us require us to meet several conditions and may be terminated or reduced in the future, which would increase our costs and taxes.

Our investment program in equipment at our facility in Hod-Hasharon, Israel, has been granted approved enterprise status and we are therefore eligible for tax benefits under the Israeli Law for the Encouragement of Capital Investments, 1959, referred to as the Investments Law. We also have been granted benefited enterprise status. We expect to utilize these tax benefits after we utilize our net operating loss carry forwards. As of December 31, 2017, our net operating loss carry forwards for Israeli tax purposes amounted to approximately $53.0 million. To remain eligible for these tax benefits, we must continue to meet certain conditions stipulated in the Investments Law and its regulations and the criteria set forth in the specific certificate of approval. If we do not meet these requirements, the tax benefits would be canceled and we could be required to refund any tax benefits and investment grants that we received in the past. Further, in the future these tax benefits may be reduced or discontinued. If these tax benefits are cancelled, our Israeli taxable income would be subject to regular Israeli corporate tax rates. The standard corporate tax rate in Israel for 2018 and thereafter is scheduled to be 23.0% and was 24.0% in 2017 and 25.0% in 2016.

Effective January 1, 2011, the Investment Law was amended. Under the amended Investment Law, the criteria for receiving tax benefits were revised. Under the transition provisions of the 2011 - Amendment, a company may decide to irrevocably implement the 2011 Amendment while waiving benefits provided under the Investment law’s prior benefits programs or to remain subject to the Investment Law’s prior benefits programs. In the future, we may not be eligible to receive additional tax benefits as were made available under the Investment law prior to the 2011 Amendment. The termination or reduction of these tax benefits would increase our tax liability, which would reduce our profits. Finally, in the event of a distribution of a dividend from the abovementioned tax-exempt income, in addition to withholding tax at the following rates: (i) Israeli resident corporation – 0%, (ii) Israeli resident individual – 20% in 2014 and onwards, and (iii) non-Israeli resident – 20% in 2014 and onwards subject to a reduced tax rate under the provisions of an applicable double tax treaty, would be subject to income tax on the amount distributed in accordance with the effective corporate tax rate which would have been applied had we not enjoyed the exemption. See “ITEM 10: Additional Information—Taxation—Israeli Tax Considerations and Government Programs.”

No assurance can be given that we will be eligible to receive additional tax benefits under the Investments Law in the future. The termination or reduction of these tax benefits would increase our tax liability in the future, which would reduce our profits or increase our losses. Additionally, if we increase our activities outside of Israel, for example, by future acquisitions, our increased activities may not be eligible for inclusion in Israeli tax benefit programs.

The government grants we have received for research and development expenditures require us to satisfy specified conditions and restrict our ability to manufacture products and transfer technologies outside of Israel. If we fail to comply with these conditions or such restrictions, we may be required to refund grants previously received together with interest and penalties and may be subject to criminal charges.

We have received grants from the Israel Innovation Authority (formerly known as the Office of the Chief Scientist of the Ministry of Economy) for the financing of a portion of our research and development expenditures in Israel, pursuant to the provisions of The Encouragement of Research, Development and Innovation in Industry Law, 1984, referred to as the Research and Development Law. In the future we may not receive grants or we may receive significantly smaller grants from the Israel Innovation Authority, and our failure to receive grants in the future could adversely affect our profitability. In 2015, 2016 and 2017 we received and accrued non-royalty-bearing grants totaling $1.3 million, $0.6 million and $0.4 million, respectively, from the Israel Innovation Authority, representing 4.5%, 2.4% and 1.8%, respectively, of our gross research and development expenditures. In 2015 we qualified to participate in two non-royalty-bearing research and development programs, and in one such program in 2016 and 2017, funded by the Israel Innovation Authority to develop generic technology relevant to the development of our products. Such programs are approved pursuant to special provisions of the Research and Development Law. We were eligible to receive grants constituting of up to 50% of certain research and development expenses relating to these programs. Although the grants under these programs are not required to be repaid by way of royalties, the restrictions of the Research and Development Law described below apply to these programs.

The provisions of the Research and Development Law and the terms of the Israel Innovation Authority grants prohibit us from transferring manufacturing products which we originally planned to manufacture in Israel outside of Israel if they incorporate technologies funded by the Israel Innovation Authority, and from transferring intellectual property rights in technologies developed using these grants, without special approvals from the Israel Innovation Authority.

Even if we receive approval to manufacture our products outside of Israel, we may be required to pay an increased total amount of royalties, which may be up to 300% of the grant amount plus interest, depending on the manufacturing volume that is performed outside of Israel. This restriction may impair our ability to outsource manufacturing or engage in similar arrangements for those products or technologies. Know-how developed under an approved research and development program may not be transferred to any third-parties, except in certain circumstances and subject to prior approval. Similarly, even if we receive approval to transfer intellectual property rights in technologies developed using these grants, we may be required to repay a multiple of the original grants plus LIBOR interest to the Israel Innovation Authority. In addition, if we fail to comply with any of the conditions and restrictions imposed by the Research and Development Law or by the specific terms under which we received the grants, we may be required to refund any grants previously received together with interest and penalties, and may be subject to criminal charges.

It may be difficult to enforce a U.S. judgment against us, our officers and directors in Israel or the United States, or to assert U.S. securities laws claims in Israel or serve process on our officers and directors.

We are incorporated in Israel. The majority of our executive officers and directors are not residents of the United States, and the majority of our assets and the assets of these persons are located outside the United States. Therefore, it may be difficult for an investor, or any other person or entity, to enforce a U.S. court judgment based upon the civil liability provisions of the U.S. federal securities laws against us or any of these persons in a U.S. or Israeli court, or to effect service of process upon these persons in the United States. Additionally, it may be difficult for an investor, or any other person or entity, to assert U.S. securities law claims in original actions instituted in Israel. Israeli courts may refuse to hear a claim based on a violation of U.S. securities laws on the grounds that Israel is not the most appropriate forum in which to bring such a claim. Even if an Israeli court agrees to hear a claim, it may determine that Israeli law and not U.S. law is applicable to the claim. If U.S. law is found to be applicable, the content of applicable U.S. law must be proved as a fact which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Israeli law. There is little binding case law in Israel addressing the matters described above.

Provisions of Israeli law and our articles of association may delay, prevent or make undesirable an acquisition of all or a significant portion of our shares or assets.

Our articles of association contain certain provisions that may delay or prevent a change of control, including a classified board of directors. In addition, Israeli corporate law regulates acquisitions of shares through tender offers and mergers, requires special approvals for transactions involving significant shareholders and regulates other matters that may be relevant to these types of transactions. These provisions of Israeli law could delay or prevent a change in control and may make it more difficult for third-parties to acquire us, even if doing so would be beneficial to our shareholders, and may limit the price that investors may be willing to pay for our ordinary shares in the future. Furthermore, Israeli tax considerations may make potential transactions undesirable to us or to some of our shareholders. See “ITEM 10: Additional Information—Memorandum and Articles of Association—Acquisitions under Israeli Law” and “—Anti-Takeover Measures.”

Industry Background

The rapid proliferation of broadband networks in recent years has been largely driven by demand from users for faster and more reliable access to the Internet and by the proliferation in the number and complexity of broadband applications, as well as the proliferation of mobile smartphones, tablets and other Internet-connected devices.

Rising Network Operational Costs Due to the Rapid Adoption of Broadband Applications

Advances in broadband access (such as the introduction of long-term evolution, or LTE, technology) combined with the advanced data capabilities of end-user devices (such as smartphones and tablets) have promoted a growing number of applications and content delivered over broadband networks. The vast majority of these applications run over-the-top of the network, which means they are not originated, controlled or charged by the network operator. The use of OTT applications, such as streaming video, peer-to-peer (P2P), Voice over IP (VoIP), social networks, interactive gaming and online content, requires large and increasing amounts of bandwidth. Moreover, many of these applications are highly sensitive to network delays caused by congestion. In response to these challenges, service providers have been forced to invest heavily in network infrastructure upgrades and customer support services in order to maintain the quality of experience for subscribers.

Rising Data Traffic in Mobile Networks

The mobile data market continues to grow rapidly, fueled by the proliferation of smartphones and tablets, mobile-enabled laptops that use mobile modems or tethered smartphones to connect to the Internet. On average, the data traffic generated by an Internet user with a smartphone is multiple times that of an Internet user without a smartphone.

The cost of increasing the bandwidth in mobile networks is significantly higher than that in wireline networks. As a result, mobile operators are experiencing economic and infrastructure challenges in meeting the rising tide of data traffic over their networks. In addition, as capacity increases in mobile networks, smartphone users are likely to have increased expectations with respect to speed and performance.

It is becoming increasingly apparent that unmanaged 4G/LTE mobile networks (and soon also 5G mobile networks) will not be able to cope with the rising tide of data traffic, without implementing intelligent bandwidth management solutions. Moreover, network providers may need to develop new pricing models if they are not able to monetize the OTT traffic carried by their networks.

Service Providers Demand the Ability to Offer Services that Can Be Monetized at Different Rates

Some service providers still offer flat-rate broadband access, regardless of the type of applications and data used by subscribers. These operators provide the same level of service to all subscribers and do not guarantee access quality, regardless of a subscriber’s willingness to pay for premium services and network performance. However, with the increasing amount of data used, the flat-rate pricing model may not be profitable, especially for mobile broadband operators, unless they can charge subscribers high rates. As a result, both mobile and fixed operators have begun to offer service plans based on gigabytes of data used. However, this pricing model is also subject to competition from other service providers offering lower rates, contributing to downward pricing pressure and high subscriber turnover rates.

To address these issues and increase the average revenue per user (ARPU), a significantly increased number of service providers have begun to offer premium, differentiated services, such as free usage for specific applications, content bundling, off-peak usage incentives, security services, improved quality for VoIP and Internet video, among others. By offering such tiered services and charging subscribers according to the value of these services, as well as based on the gigabyte usage, service providers can capitalize on the revenue opportunities embodied in their networks. To offer premium services and to guarantee high-quality delivery of content and user experience, service providers need enhanced visibility into and control of network traffic, including visibility into the type of applications used on the network and levels of traffic generated by different subscribers.

The Challenge of Elevating the Role of Fixed and Mobile Broadband Networks

In the evolving digital lifestyle, consumers recognize the importance of the devices they use to access the Internet and choose the Internet content and services they use based on quality. However, the network that connects them to the Internet is not as “visible”, and is therefore not as highly valued, even though it plays a critical role in the service chain. In order to generate revenue through various pricing models and encourage consumers and content providers to seek higher quality network services, service providers are seeking to elevate the role of network connectivity and services. To do so, service providers must be able to identify and leverage the business intelligence in their data networks and capitalize on the network traffic that they generate.

The ability to identify, distinguish and prioritize different applications plays a major role in intelligent management of network resources and service delivery, allowing service providers to optimize bandwidth utilization and reduce operational costs, while maintaining high quality of service for tiered and premium services. Application designers are employing increasingly sophisticated methods to avoid detection by network operators who desire to manage network use. Traditional network infrastructure devices, such as routers and switches, do not generally have sufficient computing resources or the required algorithms to distinguish between different and rapidly evolving applications.

Network Security Threats

As reliance on the Internet has grown, service provider and enterprise networks have become increasingly vulnerable to a wide range of security threats, including distributed denial of service attacks, spambots malware and other threats. These attacks are designed to flood the network with traffic that consumes all the available bandwidth and hinder the ability to provide high quality broadband access to subscribers or to prevent enterprises from using mission-critical applications. These threats also compromise network and data integrity. We believe service providers and enterprises must protect against such attacks by detecting and neutralizing malicious traffic at very early stages before such threats can compromise network integrity and services.

End-User Security Threats

Broadband devices, especially mobile devices, are increasingly vulnerable to online threats such as malware and phishing. Since most broadband users have limited cyber-security expertise, they become easy targets for cybercriminals. Mobile device users are even more exposed since the threat awareness is lower than that of PC users. There are several options to safeguard broadband users on-the-go. We believe service providers must protect their subscribers by providing security-as-a-service so that individual and business customers are always protected seamlessly from the network security threats.

Enterprise Demand for Visibility and Delivery of Mission-Critical Applications and Services in the Cloud

The proliferation of network applications, bring your own device and cloud computing present significant challenges for enterprises that operate data centers, wide-area networks, virtual private networks (VPN) and Internet connectivity for organizations of all sizes. Enterprises depend on network infrastructure to ensure the delivery of business-critical applications to an increasingly mobile and often global workforce, and as such, face many of the same issues as service providers. At the same time, Internet access has introduced a wide variety of recreational and non-business applications to enterprise networks, resulting in network congestion and negatively impacting employee productivity. As a result, there is an increasing need for enterprises to be able to monitor and control the traffic on their business networks.

Customers

We have a global, diversified customer base consisting primarily of mobile and fixed service providers, cable operators, private networks, data centers, governments and enterprises. We derive a significant and growing portion of our revenue from direct sales to large mobile and fixed-line service providers. We generate the remainder of our revenue through a select and well-developed network of channel partners, generally consisting of distributors, resellers, OEMs and system integrators. We also endeavor to increase our sales to enterprises and have adapted the structure of our sales organization to this end. In 2017, we derived 49% of our revenues from Europe, 19% from the Americas, 17% from Asia and Oceania and 15% from the Middle East and Africa. For a breakdown of total revenues by geographic location, see “ITEM 5.A – Operating Results – Results of Operations – Revenues.”

Channel Partners

We market and sell our products to end-customers both by direct sales and through channel partners, which include distributors, resellers, OEMs and system integrators. A significant portion of our sales occur through our channel partners. In 2017, approximately 50% of our revenues were derived from channel partners. Our channel partners are responsible for installing and providing initial customer support for our products. Our channel partners are located around the world and address most major markets. Our channel partners target a range of end-users, including carriers, alternative carriers, cable operators, private networks, data centers and enterprises in a wide range of industries, including government, financial institutions and education. Our agreements with channel partners that are distributors or resellers are generally non-exclusive, for an initial term of one year and automatically renew for successive one-year terms unless terminated. After the first year, such agreements may typically be terminated by either party upon ninety days prior notice.

We offer support to our channel partners. This support includes the generation of leads through marketing events, seminars and web-based leads and incentive programs as well as technical and sales training.

Sales and Marketing

Our product sales cycle varies based on the intended use by the end-customer. The sales cycle for initial network deployment may generally last between twelve and eighteen months for large and medium service providers, six to twelve months for small service providers, and one to six months for enterprises. Follow-on orders and additional deployment of our products usually require shorter cycles. Large and medium service providers generally take longer to plan the integration of our solutions into their existing networks and to set goals for the implementation of the technology.

We focus our marketing efforts on product positioning, increasing brand awareness, communicating product advantages and generating qualified leads for our sales organization. We rely on a variety of marketing communications channels, including our website, trade shows, industry research and professional publications, the press and special events to gain wider market exposure.

We have organized our worldwide sales efforts into the following regions: North America, South America, Europe, the Middle East and Africa; and Asia and Oceania. We have regional offices in the United States, Israel, France, United Kingdom, Spain, Colombia, Singapore, China, Italy and India and a regional presence in Germany, Mexico, Hong Kong, South Africa, Japan, New Zealand and Australia.

As of December 31, 2017, our sales and marketing staff, including product management and business development functions, consisted of 122 employees.

Service and Technical Support

We believe our technical support and professional services capabilities are a key element of our sales strategy. Our technical staff provides project management, delivery, training, support and professional services, as well as assists in presale activities and advises channel partners on the integration of our solutions into end-customer networks. Our basic warranty to end-customers (directly or through our partners) is three months for software and twelve months for hardware. Generally, end-customers are also offered a choice of one year or multi-year customer support programs when they purchase our products. These customer support programs can be renewed at the end of their terms. Our end-customer support plans generally offer the following features:

unlimited 24/7 access to our global support organization, via phone, email and online support system, provided by regional support centers;

expedited replacement units in the event of a warranty claim;

software updates and upgrades offering new features and protocols and addressing new and changing network applications; and

periodic updates of solution documentation, technical information and training.

Our support plans are designed to maximize network up-time and minimize operating costs. Our customers, including partners and their end-customers, are entitled to take advantage of our around-the-clock technical support which we provide through our seven support centers, located in France, Israel, Singapore, India, Colombia Spain and the United States. We also offer our customers, 24-hour access to an external web-based technical knowledge base, which provides technical support information and, in the case of our channel partners, enables them to support their customers independently and obtain follow up and support from us.

Many of our strategic customers purchase special support contracts, which include specifics service levels (for example, with respect to response time, restoration time, resolution time, on-site support, spare parts management, and resident engineers).

We also offer particular professional services, such as, network audit, solution design, project management, business intelligence reports, customer project documentation, integration services, interoperability testing and training and specific customizations.

The expenditures associated with the technical support staff are allocated in our statements of comprehensive loss between sale and marketing expenses and cost of goods sold, based on the roles of and tasks performed by personnel.

As of December 31, 2017, our technical staff consisted of 128 employees, including 67 technical support persons, 53 deployment and professional services engineers, six documentation and training persons, and two Customer Success managers.

Research and Development

Our research and development activities take place primarily in Israel. We also have research and development activities in Spain and Mexico. As of December 31, 2017, 117 of our employees in Israel, 43 of our employees in Spain and three of our employees in Mexico, were engaged primarily in research and development. We devote a significant amount of our resources towards research and development in order to introduce new products and continuously enhance existing products and to support our growth strategy. We have assembled a core team of experienced engineers, many of whom are leaders in their particular field or discipline and have technical degrees from top universities and have experience working for leading Israeli or international networking companies. These engineers are involved in advancing our core technologies, as well as in applying these core technologies to our product development activities. In previous years, our research and development efforts have benefited from royalty-bearing grants from the Israel Innovation Authority. As of December, 31 2017, there are no outstanding royalties due from us to the Israel Innovation Authority. In 2017, we benefited from additional grants from the Israel Innovation Authority; however, these grants do not bear royalties. Under the terms of those grants we are required to perform our manufacturing activities within the state of Israel, as a condition to maintaining these benefits. The State of Israel does not own any proprietary rights in technology developed with the Innovation Authority funding and there is no restriction related to the Israel Innovation Authority on the export of products manufactured using technology developed with the Israel Innovation Authority funding (other limitations on export apply under applicable law). For a description of restrictions on the transfer of the technology and with respect to manufacturing rights, please see “ITEM 3: Key Information—Risk Factors—The government grants we have received for research and development expenditures require us to satisfy specified conditions and restrict our ability to manufacture products and transfer technologies outside of Israel. If we fail to comply with these conditions or such restrictions, we may be required to refund grants previously received together with interest and penalties and may be subject to criminal charges.”

Manufacturing

We subcontract the manufacture and repair of the hardware components of our Service Gateway Tera platform to Flex (Israel) Ltd., which manufactures these components in accordance with our design. This strategy enables us to reduce our fixed costs, focus on our core research and development competencies and provide flexibility in meeting market demand. Flex (Israel) is contractually obligated to provide us with manufacturing services based on agreed specifications, including manufacturing, assembling, testing, packaging and procuring the raw materials for our devices. We are not required to provide any minimum orders. Our agreement with Flex (Israel) is automatically renewed annually for additional one-year terms. Flex (Israel) may terminate our agreement with them at any time during the term upon prior notice. We retain the right to procure independently any of the components used in our products. Flex (Israel) has affiliates outside of Israel, to which it can, with the prior consent of the Israel Innovation Authority, transfer manufacturing of our products if necessary, in which event we may be required to pay increased royalties to the Israel Innovation Authority.

We subcontract the integration of our security software products with an off-the- shelf hardware platforms provided by Lenovo and Hewlett Packard Enterprise (HP). Based on verbal understandings, Arrow ocs (Israel) performs the integration of the software product with HP servers, while Malam-Team (Israel) performs the integration of such software with Lenovo Servers. Such hardware components are manufactured in accordance with our design.

We design and develop internally a number of the key components for our products, including printed circuit boards. Some of the hardware components of our products are obtained from single or limited sources. Since our products have been designed to incorporate these specific components, any change in these components due to an interruption in supply or our inability to obtain such components on a timely basis may require engineering changes to our products before we could incorporate substitute components. In particular, we purchase the central processing unit for our Service Gateway platforms and for our NetEnforcer products from NetLogic Microsystems, Inc. (now part of Broadcom Corporation, recently acquired by Avago). We also purchase off the shelf hardware components from single or limited sources for our security and Traffic Management products. We carry approximately three to six months of inventory of key components. We also work closely with our suppliers to monitor the end-of-life of the product cycle for integral components, and believe that in the event that they announce end of life, we will be able to increase our inventory to allow enough time for replacing such components. The agreements with our suppliers do not contain any minimum purchase or supply commitments. Product testing and quality assurance is performed by our contract manufacturer using tests and automated testing equipment and according to controlled test documentation we specify. We also use inspection testing and statistical process controls to assure the quality and reliability of our products.

Competition

We compete against large companies in a rapidly evolving and highly competitive sector of the networking technology market, which offer, or may offer in the future, competing technologies, including partial or alternative solutions to operators' and enterprises’ challenges, and which, similarly to us, intensely pursue the largest service providers (referred to as Tier 1 operators) as well as large enterprises. Our DPI technology enabled offerings face significant competition from router and switch infrastructure companies that integrate functionalities into their platforms addressing some of the same types of issues that our products are designed to address.

Our security products, which are offered to operators and are deployed in their networks for the purpose of enabling them to provide security services to their end customers, are subject to competition from companies which offer security products, based on different technology and marketing and sales approaches. Generally, we compete on the basis of product performance, ease of use and installation, customer support and price.

Our security product offerings face significant competition from companies that directly approach end customers and offer them security applications to be installed on their devices; companies that approach the business enterprise sector through distribution channels and offer cloud security products; and companies that offer security products bundled with other products. By offering our security products to operators that provide security services to both business enterprises and individual end customers, we aim to expand the reach of our products.

See “ITEM 3: Key Information—Risk Factors—Our revenues and business may be adversely affected if we do not effectively compete in the markets in which we operate.”

Intellectual Property

Our intellectual property rights are very important to our business. We believe that the complexity of our products and the know-how incorporated into them makes it difficult to copy them or replicate their features. We rely on a combination of confidentiality and other protective clauses in our agreements, copyright and trade secrets to protect our know-how. We also restrict access to our servers physically and through closed networks since our product designs and software are stored electronically and thus are highly portable.

We customarily require our employees, subcontractors, customers, distributors, resellers, software testers, technology partners and contractors to execute confidentiality agreements or agree to confidentiality undertakings when their relationship with us begins. Typically, our employment contracts also include assignment of intellectual property rights for all inventions developed by employees, non-disclosure of all confidential information, and non-compete clauses, which generally restrict the employee for six months following termination of employment. The enforceability of non-compete clauses in certain jurisdictions in which we operate may be limited. See “ITEM 3: Key Information—Risk Factors— If we are unable to successfully protect the intellectual property embodied in our technology, our business could be harmed significantly.” Because our product designs and software are stored electronically and thus are highly portable, we attempt to reduce the portability of our designs and software by physically protecting our servers through the use of closed networks, which prevent external access to our servers.

The communications equipment industry is characterized by constant product changes resulting from new technological developments, performance improvements and lower hardware costs. We believe that our future growth depends to a large extent on our ability to be an innovator in the development and application of hardware and software technology. As we develop the next generation products, we intend to pursue patent protection for our core technologies in the telecommunications segment. We plan to seek patent protection in our largest markets and our competitors’ markets, for example in the United States and Europe. As we continue to move into new markets, such as Japan, Korea and China, and Latin America countries we will evaluate how best to protect our technologies in those markets. We intend to vigorously prosecute and defend the rights of our intellectual property.

As of December 31, 2017, we had 17 issued U.S. patents. We expect to formalize our evaluation process for determining which inventions to protect by patents or other means. We cannot be certain that patents will be issued as a result of the patent applications we have filed.

We have obtained a U.S. trademark registration for one of our key marks that we use to identify our products or services: “NetEnforcer.”

ITEM 5: Operating and Financial Review and Prospects

The information contained in this section should be read in conjunction with our consolidated financial statements for the year ended December 31, 2017 and related notes and the information contained elsewhere in this annual report. Our financial statements have been prepared in accordance with U.S. GAAP. This discussion contains forward-looking statements that are subject to known and unknown risks and uncertainties. As a result of many factors, such as those set forth under “ITEM 3.D: Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements,” our actual results may differ materially from those anticipated in these forward-looking statements.

A. Operating Results

Overview

We are a leading global provider of network intelligence and security solutions that enable service providers and enterprises to protect and personalize the digital experience and monetize on their networks. Allot’s flexible and highly scalable service delivery framework leverages the intelligence in data networks, enabling service providers to get closer to their customers, safeguard network assets and users, and accelerate time-to-revenue for value-added services. Our customers use our solutions to create sophisticated policies to monitor network applications, enforce quality of service policies that guarantee mission-critical application performance, mitigate security risks and leverage network infrastructure investments. Demand from users for faster and more reliable access to the Internet, an increase in the number and complexity of broadband applications, and growth in mobile data-enhanced smartphones have resulted in the rapid proliferation of broadband access networks in recent years. Our carrier-class products are used by service providers to offer subscriber-based and application-based tiered services that enable them to optimize their service offerings, reduce churn rates and increase ARPU.

We market and sell our products through a variety of channels, including direct sales and through our channel partners, which include distributors, resellers, OEMs and system integrators. End customers of our products include carriers, mobile operators, cable operators, wireless, wireline and satellite Internet service providers, educational institutions, governments and enterprises. The resulting intelligent, content-aware broadband networks enable our customers to accurately monitor and manage IP traffic per application, subscriber, network topology and device.

In 2017, the primary drivers of our revenues were the mobile and fixed markets, which were highlighted by our ongoing relationship with global Tier 1 mobile and fixed operators groups.

In 2012, we acquired the business of Ortiva Wireless Inc. (“Ortiva”), a developer of solutions for mobile and Internet networks and Oversi Networks Ltd. (“Oversi”), a developer of products and systems for caching Internet content.

In March 2015, we acquired the business and substantially all of the assets of Optenet, S.A., a developer of security solutions for internet service providers and enterprises. Under the terms of the agreement, the consideration includes approximately $9.9 million (€8.9 million) in cash. In addition, there is a performance-based earn-out over a period of five years following closing, which is capped at approximately $27.5 million (€25 million) and is contingent upon reaching certain revenues threshold from sale of Optenet products. The fair value of the contingent consideration as of the acquisition date was estimated at $8.1 million (€7.3 million). See Note 1(b) to our consolidated financial statements for further information.

In January 2018, we acquired all of the outstanding shares of Netonomy Ltd., a developer of software-based cyber security for the connected home. Under the terms of the agreement, the consideration includes approximately $3.2 million in cash. In addition, there is a performance-based contingent amount, over a period of two and a half years following closing, which is capped at approximately $1.1 million.

Key measures of our performance

Revenues

We generate revenues from two sources: (1) sales of our network traffic management systems and our network management application solutions and platforms, and (2) maintenance and support services and professional services, including installation and training. We generally provide maintenance and support services pursuant to a one- to three-year maintenance and support program, which may be purchased by customers at the time of product purchase or on a renewal basis.

We recognize revenues from product sales when persuasive evidence of an agreement exists, delivery of the product has occurred, no significant obligations with respect to implementation remain, the fee is fixed or determinable and collection is probable. We typically grant a one-year hardware and three-month software warranty on all of our products, or one-year hardware and software warranty to customers that purchase annual maintenance and support. Typically our support contracts with our customers, provide hot line support, warranty, software updates and upgrades, if and when available. We record a provision for warranty at the time the product’s revenue is recognized. We estimate the liability of possible warranty claims based on our historical experience. Warranty claims have to date been immaterial to our results of operations. Maintenance and support revenues are recognized on a straight-line basis over the term of the applicable maintenance and support agreement. See “—Critical Accounting Policies and Estimates—Revenue Recognition” below.

Customer concentration. We derived 32% of our total revenues in 2017 from one Tier 1 mobile and fixed operator. In 2016 and 2015, we derived 42% and 37% of our total revenues from two Tier 1 mobile and fixed operators, respectively.

Geographical breakdown. See “ITEM 4B: Information on Allot—Business Overview—Customers” for the geographic breakdown of our revenues by percentage for the years ended December 31, 2015, 2016 and 2017.

Cost of revenues and gross margins

Our products’ cost of revenues consists primarily of costs of materials, manufacturing services and overhead, warehousing and product testing. Our services’ cost of revenues consists primarily of salaries and related personnel costs for our customer support staff. We expect our percentage of gross margin to remain at the same level as in 2017. In 2015 our gross margin decreased, primarily due to intangible assets impairment of $5.8 million derived from Oversi’s and Ortiva’s technologies acquired in 2012 due to our decision to reach end of life on the respective product lines. In 2016 we recorded no intangible assets impairment and as a result our gross margin increased compared to 2015. In 2017, our gross margin decreased compared to 2016, due to an increase in projects which required a higher portion of services and the weakening of the U.S. dollar mainly against the ILS and the Euro.

Operating expenses

Research and development. Our research and development expenses consist primarily of salaries and related personnel costs, costs for subcontractor services, depreciation, rent and costs of materials consumed in connection with the design and development of our products. We expense all of our research and development costs as they are incurred. Our net research and development expenses are comprised of gross research and development expenses offset by financing through grants from the Israel Innovation Authority. Such participation grants are recognized at the time at which we are entitled to such grants on the basis of the costs incurred and included as a deduction of research and development expenses (see - “Government Grants” below). We believe that significant investment in research and development, including hiring high quality research and development personnel, is essential to our future success.

Sales and marketing. Our sales and marketing expenses consist primarily of salaries and related personnel costs, travel expenses, costs associated with promotional activities such as public relations, conventions and exhibitions, rental expenses, depreciation and commissions paid to third parties, promote our brand, establish new marketing channels and expand our presence worldwide.

General and administrative. Our general and administrative expenses consist of salaries and related personnel costs, rental expenses, costs for professional services and depreciation. General and administrative expenses also include costs associated with corporate governance, tax and regulatory compliance, compliance with the rules implemented by the SEC, NASDAQ and the Tel-Aviv Stock Exchange (“TASE”) and premiums for our director and officer liability insurance.

Approved Enterprise

Our facilities in Hod-Hasharon, Israel have been granted Approved Enterprise status under the Encouragement of Capital Investments Law, 1959, and enjoy certain tax benefits under this program. We expect to utilize these tax benefits after we utilize our net operating loss carry forwards. As of December 31, 2017, our net operating loss carry forwards for Israeli tax purposes totaled approximately $53.0 million, which includes losses related to our acquisition of Oversi. As a result of our acquisition of Oversi, we may offset operating losses in Israel against taxable income annually with a limitation of up to 14% of the total accumulated loss but no more than 50% of our taxable income. Income derived from other sources, other than through our “Approved Enterprise” status, during the benefit period will be subject to the regular corporate tax rate.

Government Grants

Our research and development efforts have been financed, in part, through grants from the Israel Innovation Authority under our approved plans in accordance with the Research and Development Law. In 2015, 2016 and 2017 we received grants from the Israel Innovation Authority through non-royalty bearing programs.

Factors Affecting Our Performance

Our business, financial position and results of operations, as well as the period-to-period comparability of our financial results, are significantly affected by a number of factors, some of which are beyond our control, including:

Customer concentration. We derived 32% of our total revenues in 2017 from one global Tier 1 mobile and fixed operator groups. While we have some visibility into the likely scope of the customers’ projects, our relationships are conducted solely on a purchase order basis and we do not have any commitment for future purchase orders from these customers. The loss of any of such significant customers could harm our results of operations and financial condition.

Size of end-customers and sales cycles. We have a global, diversified end-customer base consisting primarily of service providers and enterprises. The deployment of our products by small and midsize enterprises and service providers can be completed relatively quickly. Large service providers take longer to plan the integration of our solutions into their existing networks and to set goals for the implementation of the technology. Sales to large service providers are therefore more complicated as they involve a relatively larger number of network elements and solutions. We are seeking to achieve further significant customer wins in the large service provider market that would positively impact our future performance. The longer sales cycles associated with the increased sales to large service providers of our platforms may increase the unpredictability of the timing of our sales and may cause our quarterly and annual operating results to fluctuate if a significant customer delays its purchasing decision and/or defers an order. Furthermore, longer sales cycles may result in delays from the time we increase our operating expenses and make investments in inventory to the time that we generate revenue from related product sales.

Average selling prices. Our performance is affected by the selling prices of our products. We price our products based on several factors, including manufacturing costs, the stage of the product’s life cycle, competition, technical complexity of the product, and discounts given to channel partners in certain territories. We typically are able to charge the highest price for a product when it is first introduced to the market. We expect that the average selling prices for our products will decrease over the product’s life cycle as our competitors introduce new products. In order to maintain or increase our current prices, we expect that we will need to enhance the functionality of our existing products by offering higher system speeds, additional products and features, such as additional security functions, supporting additional applications and providing enhanced reporting tools. We also from time to time introduce enhanced products, typically higher-end models that include new architecture and design and new capabilities. Such enhanced products typically increase our average selling price. To further offset such declines, we sell maintenance and support programs for our products, and as our customer base and number of field installations grow, our related service revenues are expected to increase.

Cost of revenues and cost reductions. Our cost of revenues as a percentage of total revenues was 33.4% for 2015, 30.9% for 2016 and 34.8% for 2017. Our products use off-the-shelf components and typically the prices of such components decline over time. However, the introduction and sale of new or enhanced products and services may result in an increase in our cost of revenues. We make a continuous effort to identify cheaper components of comparable performance and quality. We also seek improvements in engineering and manufacturing efficiency to reduce costs. Our products incorporate features that are purchased from third parties. In addition, new products usually have higher costs during the initial introduction period. We generally expect such costs to decline as the product matures and sales volume increases. The introduction of new products may also involve a significant decrease in demand for older products. Such a decrease may result in a devaluation or write-off of such older products and their respective components. The growth of our customer base is usually coupled with increased service revenues primarily resulting from increased maintenance and support. In addition, the growth of our installed base with large service providers may result in increased demand for professional services, such as training and installation services. An increase in demand for such services may require us to hire additional personnel and incur other expenditures. However, these additional expenses, handled efficiently, may be utilized to further support the growth of our customer base and increase service revenues. The increase of our cost of revenues in 2015 was primarily due to intangibles assets impairment of $5.8 million derived from Oversi’s and Ortiva’s technologies acquired in 2012 due to our decision to phase out the respective product lines. In 2016 we recorded no intangible assets impairment and as a result our gross margin increased compared to 2015. In 2017 our cost of revenues slightly increased mainly due to an increase in projects which require a higher portion of services and the weakening of the U.S. dollar mainly against the ILS and the Euro.

Currency exposure. A majority of our revenues and a substantial portion of our expenses are denominated in the U.S. dollar. However, a significant portion of our revenues is incurred in currencies other than U.S. dollar, mostly in Euro. In addition, a significant portion of our expenses, associated with our global operations, including personnel and facilities-related expenses, are incurred in currencies other than the U.S. dollar; this is the case primarily in Israel and to a lesser extent in other countries in Europe and Asia. Consequently, a decrease in the value of the U.S. dollar relative to local currencies will increase the dollar cost of our operations in these countries. A relative decrease in the value of the U.S. dollar would be partially offset to the extent that we generate revenues in such currencies. In order to partially mitigate this exposure we have decided in the past and may decide from time to time in the future to enter into hedging transactions. We may discontinue hedging activities at any time. As such decisions involve substantial judgment and assessments primarily regarding future trends in foreign exchange markets, which are very volatile, as well as our future level and timing of cash flows of these currencies, we cannot provide any assurance that such hedging transactions will not affect our results of operations when they are realized. See Note 5 to our consolidated financial statements included elsewhere in this annual report for further information. Also see “ITEM 11: Quantitative and Qualitative Disclosure About Market Risk.”

Interest rate exposure. We have a significant amount of cash that is currently invested primarily in interest bearing vehicles, such as bank time deposits and available for sale marketable securities. These investments expose us to risks associated with interest rate fluctuations. See “ITEM 11: Quantitative and Qualitative Disclosure About Market Risk.”

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles, or U.S. GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and judgments are subject to an inherent degree of uncertainty and actual results may differ. Our significant accounting policies are more fully described in Note 2 to our consolidated financial statements included elsewhere in this annual report. Certain of our accounting policies are particularly important to the portrayal of our financial position and results of operations. In applying these critical accounting policies, our management uses its judgment to determine the appropriate assumptions to be used in making certain estimates. Those estimates are based on our historical experience, the terms of existing contracts, our observance of trends in our industry, information provided by our customers and information available from other outside sources, as appropriate. With respect to our policies on revenue recognition and warranty costs, our historical experience is based principally on our operations since we commenced selling our products in 1998. Our estimates are primarily guided by observing the following critical accounting policies:

Revenue recognition;

Provision for returns;

Business combinations

Allowance for doubtful accounts;

Accounting for stock-based compensation;

Inventories;

Marketable securities;

Impairment of goodwill and long lived assets;

Income taxes; and

Contingent liabilities.

Contingent Consideration.

Because each of the accounting policies listed above requires the exercise of certain judgments and the use of estimates, actual results may differ from our estimations and as a result would increase or decrease our future revenues and net income.

Revenue recognition.

We account for revenue recognition in accordance with Accounting Standards Codification No. 605-25, “Multiple elements arrangements” (“ASC No. 605-25”). We generate revenues mainly from selling our products along with related maintenance and support services. At times, these arrangements may also include professional services, such as installation services or training. We generally sell our products through resellers, distributors, OEMs and system integrators, all of whom are considered end-users.

Revenues from product sales are recognized when persuasive evidence of an agreement exists, title and risk of loss have transferred to the customer, no significant performance obligations remain, payment for products is not contingent upon performance of installation or service obligations, the fee is fixed or determinable and collectability is probable. In instances where final acceptance of the product or service is specified by the customer, we do not recognize the revenue until all acceptance criteria have been met.

Maintenance and support related revenues included in multiple element arrangements are deferred and recognized on a straight-line basis over the term of the applicable maintenance and support agreement. Other services, such as professional services, are recognized upon the completion of installation or when the service is provided. In instances where the services provided in a multiple element arrangement are considered essential to the functionality of the product and payment of the product is contingent upon performance of the services, the sales of the products and services would be considered one unit of accounting. Deferred revenues are classified as short and long term based on their contractual term and recognized as revenues at the time the respective elements are provided.

Revenues arrangements with multiple deliverables are allocated using the relative selling price method. We determine the best estimated selling price (“BESP”) in multiple elements arrangements as follows:

For the products, we determined the “BESP” based on management’s estimated selling price by reviewing historical transactions and considering multiple other factors, including but not limited to, pricing practices including discounting, and competition.

For the maintenance and support, the Company determined BESP based on VSOE of the price charged based on standalone sales (renewals) of such elements using a consistent percentage of the Company's product price lists in the same territories.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products are transferred to customers. Subsequently, the FASB has issued the following standards related to ASU 2014-09: ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (“ASU 2016-08”); ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing (“ASU 2016-10”); ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”); and ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers (“ASU 2016-20”). The Company must adopt ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20 with ASU 2014-09 (collectively, the “new revenue standards”).

Under the standard, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers.

The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method). We will adopt the standard using the modified retrospective method to restate each prior reporting period presented.

The standard became effective for us beginning in 2018 fiscal year. In preparation for adoption of the standard, we have implemented internal controls and key system functionalities to enable the preparation of financial information and have reached conclusions on key accounting assessments related to the standard, including our assessment that the impact of accounting for costs incurred to obtain a contract is immaterial.

The most significant impact of the new standard relates to the way the Company accounts for term-based license agreements. Specifically, under the current revenue standard, the Company recognizes both the term license and maintenance revenues ratably over the contract period whereas under the new revenue standard it would recognize term license revenues at the point in time when control transfers and the associated maintenance revenues over the contract period. We expect the adoption of the standard to result in a reduction of deferred revenues of $712 as of January 1, 2018 to be recorded in accumulated deficit due to upfront recognition of license revenues from term licenses.

Provision for returns. We provide a provision for product returns based on its experience with historical sales returns. Such provisions amounted to $0.7, $0.9 million and $0.7 million as of December 31, 2017, 2016 and 2015, respectively.

Business combinations. We account for our business acquisitions in accordance with Accounting Standards Codification (ASC) No. 805, Business Combinations. We use management best estimates and assumptions as part of the purchase price allocation process to value assets acquired and liabilities assumed at the business combination date. The total purchase price allocated to the tangible assets acquired is assigned based on the fair values as of the date of the acquisition.

Allowance for doubtful accounts. We evaluate the collectability of our accounts receivable on a specific basis. We estimate this allowance based on our judgment as to our ability to collect outstanding receivables. We primarily base this judgment on an analysis of significant outstanding invoices, the age of the receivables, our historical collection experience and current economic trends. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations to us, we record a specific allowance against amounts due to reduce the net recognized receivable to the amount we reasonably believe will be collected.

Accounting for stock-based compensation. We account for stock-based compensation in accordance with Accounting Standards Codification No. 718, “Compensation - Stock Compensation” (“ASC No. 718”) that requires companies to estimate the fair value of equity-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service periods in our consolidated statement of operations. We recognize compensation expense for the value of its awards granted based on the straight-line method over the requisite service period of each of the awards, net of estimated forfeitures. ASC No. 718 requires forfeitures to be estimated at the time of the grant and revised in subsequent periods if actual forfeitures differ from those estimates.

In connection with the grant of options and RSUs, we recorded total stock-based compensation expenses of $7.2 million in 2015, $5.1 million in 2016 and $3.4 million in 2017. In 2017, $0.4 million, $0.6 million, $1.2 million and $1.2 million of our stock-based compensation expense resulted from cost of revenue, research and development expenses, net, sales and marketing expenses and general and administrative expenses, respectively, based on the department in which the recipient of the option grant was employed. As of December 31, 2017, we had an aggregate of $4.7 million of unrecognized stock-based compensation remaining to be recognized over a weighted average vesting period of 2.8 years.

Inventories are stated at the lower of cost or market value. Inventory write-offs are provided to cover risks arising from slow-moving items, technological obsolescence, excess inventory and discontinued products. Inventory write-off provision as of December 31, 2017, 2016 and 2015 totaled $2.7 million, $2.0 million, and $1.7 million, respectively.

Marketable securities. We account for our investments in marketable securities using Accounting Standards Codification No. 320, “Investments – Debt and Equity Securities” (“ASC No. 320”).

We determine the appropriate classification of marketable securities at the time of purchase and evaluate such designation as of each balance sheet date. We classify all of our investments in marketable securities as available for sale. Available for sale securities are carried at fair value, with unrealized gains and losses reported in “accumulated other comprehensive income (loss)” in shareholders’ equity. Realized gains and losses on sales of investments are included in earnings and are derived using the specific identification method for determining the cost of securities. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization together with interest and dividends on securities are included in financial income, net, if any.

As of December 31, 2017, we held available for sale marketable securities of $63.2 million. As of December 31, 2017, the unrealized loss recorded in other comprehensive income was $0.1 million.

Impairment of goodwill and long lived assets. Goodwill represents the excess of the purchase price over the fair value of net assets of purchased businesses. Under Accounting Standards Codification No. 350, “Intangibles-Goodwill and Other” (“ASC No. 350”), goodwill and intangible assets deemed to have indefinite lives are tested for impairment annually, or more often if there are indicators of impairment present.

We perform an annual impairment analysis of goodwill at December 31 of each year, or more often as applicable. We operate in one operating segment, and this segment comprises only one reporting unit. The provisions of ASC No. 350 require that a two-step impairment test be performed on goodwill at the level of the reporting units. In the first step, we compare the fair value of the reporting unit to its carrying value. If the fair value exceeds the carrying value of the net assets, goodwill is considered not impaired, and no further testing is required to be performed. If the carrying value of the net assets exceeds the fair value, then we must perform the second step of the impairment test in order to determine the implied fair value of goodwill. If the carrying value of goodwill exceeds its implied fair value, then we would record an impairment loss equal to the difference.

We believe that our business activity and management structure meet the criterion of being a single reporting unit for accounting purposes. We performed an annual impairment analysis as of December 31, 2017 and determined that the carrying value of the reporting unit was more than the fair value of the reporting unit. Fair value is determined using market capitalization. During the years ended 2015, 2016 and 2017, no impairment losses were recorded.

Intangible assets acquired in a business combination are recorded at fair value at the date of the acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and any accumulated impairment losses. The useful lives of intangible assets are assessed to be either finite or indefinite. Intangible assets that are not considered to have an indefinite useful life are amortized over their estimated useful lives. Some of the acquired intangible assets are amortized over their estimated useful lives in proportion to the economic benefits realized. This accounting policy results in accelerated amortization of such customer relationships and backlog as compared to the straight-line method. All other intangible assets are amortized over their estimated useful lives on a straight-line basis.

Property and equipment and intangible assets subject to amortization are reviewed for impairment in accordance with ASC No. 360, “Accounting for the Impairment or Disposal of Long-Lived Assets,” whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. During 2017and 2016, no impairment losses were recorded in respect of intangible assets. During 2015, we recorded impairment losses of $5.8 million in respect of intangible assets.

Income taxes. We account for income taxes in accordance with Accounting Standards Codification No. 740, “Income Taxes” (“ASC No. 740”). ASC No. 740 prescribes the use of the liability method, whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. We provide a valuation allowance, if necessary, to reduce deferred tax assets to their estimated realizable value if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

In Israel, we have accumulated operating loss carry forwards of approximately $53.0 million and capital losses of approximately $27.3 million for tax purposes as of December 31, 2017, which may be carried forward and offset against ordinary income and capital gains respectively in the future for an indefinite period. In the United States, the accumulated losses for U.S. federal income tax return purposes were approximately $5.9 million as of December 31, 2017, and expire between 2026 and 2032. We believe that because of our history of losses, and uncertainty with respect to future taxable income, it is more likely than not that some of the deferred tax assets regarding the loss carry forwards will not be utilized in the foreseeable future, and therefore, a valuation allowance was provided to reduce deferred tax assets to their realizable value. The valuation allowance for the year ended December 31, 2017 was $23.6 million.

ASC No. 740 contains a two-step approach to recognizing and measuring a liability for uncertain tax positions. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that it is more likely than not that, on an evaluation of the technical merits, the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement.

Contingent liabilities. We are, from time to time, involved in claims, lawsuits, government investigations, and other proceedings arising in the ordinary course of our business. In making a determination regarding provisions for liability, using available information, we evaluate the likelihood of an unfavorable outcome in legal or regulatory proceedings to which we are a party to and record a loss contingency when it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. These subjective determinations are based on the status of such legal or regulatory proceedings, the merits of our defenses and consultation with legal counsel. Legal proceedings are inherently unpredictable and subject to significant uncertainties, some of which are beyond our control. Should any of these estimates and assumptions change or prove to have been incorrect, it could have a material impact on our results of operations, financial position and cash flows.

Contingent Consideration. We measure liabilities related to earn-out payments at fair value at the end of each reporting period. The fair value was estimated by utilizing the future potential cash payments discounted to arrive at a present value amount, based on our expectation. The discount rate was based on the Monte-Carlo simulation method by taking into account, forecast future revenues, expected volatility and weighted average cost of debt.

Year Ended December 31, 2017 Compared to Year Ended December 31, 2016

Products. Product revenues decreased by $5.7 million, or 10.5%, to $48.7 million in 2017 from $54.4 million in 2016. The decrease in revenues in 2017 was attributable to the longer than expected sale cycles and the low backlog at the beginning of the year.

Services. Service revenues decreased by $2.6 million, or 7.2%, to $33.3 million in 2017 from $35.9 million in 2016. A material part of the sales of our Services is linked to the sales of our Products, which decreased due to the factors described above. Such factors also contributed to the decrease in Services revenues.

Product revenues comprised 59.4% of our total revenues in 2017, a decrease of 0.8% compared to 2016 while the services revenues portion of total revenues increased by 0.8%.

Cost of revenues and gross margin

Products. Cost of product revenues decreased by $1.1 million, or 5.4%, to $19.3 million in 2017 from $20.4 million in 2016. Product gross margin slightly decreased to 60.5% in 2017 from 62.5% in 2016. This increase is attributed to direct costs related to new Tier 1 projects.

Services. Cost of services revenues increased by $1.8 million, or 24.0%, to $9.3 million in 2017 from $7.5 million in 2016.

Total gross margin decreased to 65.2% in 2017 from 69.1% in 2016.

Operating expenses

Research and development. Gross research and development expenses decreased by $2.6 million, or 10.4%, to $22.2 million in 2017 from $24.8 million in 2016. Gross research and development expenses as a percentage of total revenues decreased to 27.1% in 2017 from 27.5% in 2016.

Sales and marketing. Sales and marketing expenses increased by $3.0 million, or 8.5%, to $38.3 million in 2017 from $35.3 million in 2016. The increase in our sales and marketing expenses is mainly attributable to the reorganization of our sales department implemented during 2017, which included, among others, recruitment of senior sales executives. Sales and marketing expenses as a percentage of total revenues increased to 46.7% in 2017 from 39.1% in 2016.

General and administrative. General and administrative expenses increased by $0.9 million, or 9.2%, to $10.7 million in 2017 from $9.8 million in 2016. General and administrative expenses as a percentage of revenues increased to 13.0% in 2017 from 10.9% in 2016.

Financial income, net. In 2017 we had $0.9 million financial income, net, similar to the level of income in 2016, which was $1.1 million, financial income, net.

Income tax expense. Income tax expense in 2017 was $1.6 million, compared to income tax expense of $2.2 million in 2016. the decrease in 2017 was mainly due to less write offs of unutilized withholding taxes, compared to 2016.

Year Ended December 31, 2016 Compared to Year Ended December 31, 2015

Revenues

Products. Product revenues decreased by $8.2 million, or 13.1%, to $54.4 million in 2016 from $62.6 million in 2015. The decrease in revenues in 2016 was attributable to a decrease in the number of transactions with large Tier-1 operators compared to 2015 and the sharp decrease in the EUR and other currencies against the U.S. dollar.

Services. Service revenues by $1.4 million, or 3.7%, to $35.9 million in 2016 from $37.3 million in 2015. A material portion of the sales of our Services is linked to the sales of our Products, which decreased due to the factors described above. Such factors also contributed to the decrease in Services revenues.

Product revenues comprised 60.2% of our total revenues in 2016, a decrease of 2.4% compared to 2015 while the services revenues portion of total revenues increased by 2.4%.

Cost of revenues and gross margin

Products. Cost of product revenues decreased by $6.3 million, or 23.6%, to $20.4 million in 2016 from $26.7 million in 2015. Product gross margin increased to 62.5% in 2016 from 57.4% in 2015. The decrease of our cost of product revenues in 2016 was mainly the result of an intangible assets impairment of $5.8 million in 2015 derived from Oversi’s and Ortiva’s technologies acquired in 2012 due to our decision to reach end of life on the respective product lines.

Services. Cost of services revenues increased by $0.8 million, or 11.5%, to $7.5 million in 2016 from $6.7 million in 2015. This increase was attributed to additional personnel hiring and increase in operational expenditures related to service sales.

Total gross margin increased to 69.1% in 2016 from 66.6% in 2015.

Operating expenses

During 2016, the Company endeavored to reduce its operating expenses by decreasing, among others, its head count and other operating expenses.

Research and development. Gross research and development expenses decreased by $2.8 million, or 10.3%, to $24.8 million in 2016 from $27.7 million in 2015. Research and development expenses as a percentage of total revenues increased to 27.5% in 2016 from 27.7% in 2015.

Sales and marketing. Sales and marketing expenses decreased by $8.0 million, or 18.5%, to $35.3 million in 2016 from $43.3 million in 2015.

Sales and marketing expenses as a percentage of total revenues decreased to 39.1% in 2016 from 43.3% in 2015.

General and administrative. General and administrative expenses decreased by $2.9 million, or 22.8%, to $9.8 million in 2016 from $12.7 million in 2015.

General and administrative expenses as a percentage of revenues decreased to 10.9% in 2016 from 12.7% in 2015.

Financial income, net. In 2016 we had $1.1 million financial income, net, and in 2015, we had $0.6 million financial expenses, net. The change in 2016 was primarily attributed to interest earned on our cash balances and other financial investments.

Income tax expense. Income tax expense in 2016 was $2.2 million, compared to income tax expense of $3.4 million in 2015. This decrease was due to a write-off of $2.1 million of deferred tax assets done in 2015, which was offset by an increase in write-off of unutilized withholding taxes of $0.6 million in 2016.

B. Liquidity and Capital Resources

As of December 31, 2017, we had $15.3 million in cash and cash equivalents, $63.2 million available for sale marketable securities and $31.5 million in short-term and restricted deposits. As of December 31, 2017, our working capital, which we calculate by subtracting our current liabilities from our current assets, was $111.8 million.

Based on our current business plan, we believe that our existing cash balances will be sufficient to meet our anticipated cash needs for working capital and capital expenditures for at least the next twelve months. If our estimates of revenues, expense or capital or liquidity requirements change or are inaccurate and are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or arrange additional debt financing. In addition, we may seek to sell additional equity or arrange debt financing to give us financial flexibility to pursue attractive acquisitions or investment opportunities that may arise in the future.

Operating activities.

During 2017, we used $0.2 million in cash and cash equivalents from operating activities. Net cash used in operating activities consisted mainly of a net loss of $18.1 million, depreciation, amortization and impairment of intangible assets of $3.7 million, $3.4 million of stock-based compensation expense, an increase of $0.7 million in inventory, an increase of $1.1 million in employees and payroll accruals, a decrease of $1.4 million in trade receivables, an increase of $2.6 million in trade payables, an increase of $3.5 in other payables and accrued expenses, a decrease of $1.4 million in other receivables and prepaid expenses and $1.5 million related to other operating activities.

During 2016, we used $3.5 million in cash and cash equivalents from operating activities. Net cash used in operating activities consisted mainly of a net loss of $8.0 million, depreciation, amortization and impairment of intangible assets of $4.0 million, $5.1 million of stock-based compensation expense, a decrease of $2.9 million in inventory, a decrease of $0.8 million in employees and payroll accruals, an increase of $0.3 million in trade receivables, a decrease of $4.2 million in deferred revenues attributed to sales which revenue recognition criteria were met while cash was collected in the previous years, a decrease of $3.8 million in trade payables, a decrease of $0.2 in long-term deferred taxes, net, a decrease of $0.7 million in other receivables and prepaid expenses and $0.7 million related to other operating activities.

Net cash we provided by operating activities in 2015 was $4.2 million. Net cash provided by operating activities consisted mainly of a net loss of $19.8 million, depreciation, amortization and impairment of intangible assets of $11.5 million, $7.2 million of stock-based compensation expense, an increase of $0.06 million in inventory, an increase of $0.9 million in employees and payroll accruals, an increase of $0.8 million in trade receivables, an increase of $2.0 million in deferred revenues attributed to sales which revenue recognition criteria were met while cash was collected in the previous years, an increase of $2.2 million in trade payables, a decrease of $1.4 million in long-term deferred taxes, net, an increase of $2.6 million in other receivables and prepaid expenses and $2.4 million related to other operating activities.

Investing activities.

Net cash used in investing activities in 2017 was $8.1 million, primarily attributable to an investment in available-for sale marketable securities of $30.1 million, purchase of property and equipment of $2.8 million and investment in short-term bank deposits and restricted deposits of $1.7 million. The above changes were partially offset by redemption of marketable securities of $26.5.

Net cash provided by investing activities in 2016 was $15.0 million, primarily attributable to an investment in available-for sale marketable securities of $29.7 million and the purchase of property and equipment of $1.6 million. The above changes were partially offset by redemption of marketable securities of $33.2 million and redemptions of short-term bank deposits of $12.9 million.

Net cash used in investing activities in 2015 was $7.9 million, primarily attributable to acquisitions of $9.9 million, an investment in available-for sale marketable securities of $34.1 million and the purchase of property and equipment of $2.2 million. The above changes were partially offset by redemption of marketable securities of $22.2 million and redemptions of short-term bank deposits of $16.3 million.

We expect that our capital expenditures will total approximately $2.8 million in 2018. We anticipate that these capital expenditures will be primarily related to further investments in lab equipment for research and development and for leasehold improvements.

Financing activities.

Net cash provided by financing activities in 2017 was $0.4 million, which was all attributable to issuance of share capital through the exercise of stock options and RSUs.

Net cash used in financing activities in 2016 was $3.7 million, which was attributable to issuance of share capital through the exercise of stock options and RSUs of $0.1 million and repurchase of our ordinary shares of $3.8 million.

Net cash used in financing activities in 2015 was $0.03 million, which was attributable to issuance of share capital through the exercise of stock options and RSUs of $0.13 million and repurchase of our ordinary shares of $0.17 million.

C. Research and Development, Patents and Licenses

In 2015, 2016 and 2017, we benefited from non-royalty bearing grants from the Israel Innovation Authority. The government grants we have received for research and development expenditures restrict our ability to manufacture products and transfer technologies outside of Israel and require us to satisfy specified conditions. If we fail to comply with such restrictions or these conditions, we may be required to refund grants previously received together with interest and penalties, and may be subject to criminal charges.

Total research and development expenses, before royalty bearing grants, were approximately $27.7 million, $24.8 million and 22.2 million in the years ended December 31, 2015, 2016 and 2017, respectively. Non-royalty -bearing grants amounted to $1.3 million, $0.6 million and $0.4 million, in 2015, 2016 and 2017, respectively.

As of December 31, 2017, we had 17 issued U.S. patents and no pending patent applications in the United States. We expect to formalize our evaluation process for determining which inventions to protect by patents or other means. We cannot be certain that patents will be issued as a result of the patent applications we have filed.

Our compensation policy was approved by our compensation and nominating committee and by our Board of Directors, and subsequently approved by our shareholders in August 2016, and will be in effect for a period of three years following approval. Our compensation policy provides:

Objectives: To attract, motivate and retain highly experienced personnel who will provide leadership for Allot’s success and enhance shareholder value, and to promote for each executive officer an opportunity to advance in a growing organization.

Compensation instruments: Includes base salary; benefits and perquisites; cash bonuses; equity-based awards; and retirement and termination arrangements.

Ratio between fixed and variable compensation: Allot aims to balance the mix of fixed compensation (base salary, benefits and perquisites) and variable compensation (cash bonuses and equity-based awards) pursuant to the ranges set forth in the compensation policy in order, among other things, to tie the compensation of each executive officer to Allot’s financial and strategic achievements and enhance the alignment between the executive officer’s interests and the long-term interests of Allot and its shareholders .

Internal compensation ratio: Allot will target a ratio between overall compensation of the executive officers and the average and median salary of the other employees of Allot, as set forth in the compensation policy, to ensure that levels of executive compensation will not have a negative impact on work relations in Allot.

Base salary, benefits and perquisites: The compensation policy provides guidelines and criteria for determining base salary, benefits and perquisites for executive officers.

Cash bonuses: Allot’s policy is to allow annual cash bonuses, which may be awarded to executive officers pursuant to the guidelines and criteria, including maximum bonus opportunities, set forth in the compensation policy.

“Clawback”: In the event of an accounting restatement, Allot shall be entitled to recover from current executive officers bonus compensation in the amount of the excess over what would have been paid under the accounting restatement, with a three-year look-back.

Equity-based awards: Allot’s policy is to provide equity-based awards in the form of stock options, restricted stock units and other forms of equity, which may be awarded to executive officers pursuant to the guidelines and criteria, including minimum vesting period, set forth in the compensation policy.

Retirement and termination: The compensation policy provides guidelines and criteria for determining retirement and termination arrangements of executive officers, including limitations thereon.

Exculpation, indemnification and insurance: The compensation policy provides guidelines and criteria for providing directors and executive officers with exculpation, indemnification and insurance.

Directors: The compensation policy provides guidelines for the compensation of our directors in accordance with applicable regulations promulgated under the Companies Law, and for equity-based awards that may be granted to directors pursuant to the guidelines and criteria, including minimum vesting period, set forth in the compensation policy.

Applicability: The compensation policy applies to all compensation agreements and arrangements approved after the date on which the compensation policy is approved by the shareholders.

Review: The compensation and nominating committee and the Board of Directors of Allot shall review and reassess the adequacy of the Compensation Policy from time to time, as required by the Companies Law.

C. Board Practices

Corporate Governance Practices

As a foreign private issuer, we are permitted under NASDAQ Rule 5615(a)(3) to follow Israeli corporate governance practices instead of the NASDAQ Stock Market requirements applicable to the U.S. issuers, provided we disclose which requirements we are not following and describe the equivalent Israeli requirement. See “ITEM 16G: Corporate Governance Requirements” for a discussion of those ways in which our corporate governance practices differ from those required by NASDAQ for domestic companies.

Board of Directors

Terms of Directors

Our articles of association provide that we may have not less than five directors and up to nine directors.

Under our articles of association, our directors (other than the outside directors, whose appointments are required under the Companies Law; see “—Outside Directors”) are divided into three classes. Each class of directors consists, as nearly as possible, of one-third of the total number of directors constituting the entire board of directors (other than the outside directors). At each annual general meeting of our shareholders, the election or re-election of directors following the expiration of the term of office of that class of directors is for a term of office that expires on the third annual general meeting following such election or re-election, such that each year the term of office of only one class of directors will expire.

Our Class I director, Nadav Zohar will hold office until the 2019 Annual General Meeting of Shareholders. Our Class II directors, Itzhak Danziger and Miron Kenneth, will hold office until our annual meeting of shareholders to be held in 2020. Our Class III directors, Yigal Jacoby (who also serves as our Chairman of the board of directors) and Manuel Echanove, will hold office until our annual meeting of shareholders to be held in 2018. The directors (other than the outside directors) are elected by a vote of the holders of a majority of the voting power present and voting at the meeting. Each director will hold office until the annual general meeting of our shareholders for the year in which his or her term expires and until his or her successor is duly elected and qualified, unless the tenure of such director expires earlier pursuant to the Companies Law or unless he or she resigns or is removed from office.

Under the Companies Law, a director (including an outside director) must declare in writing that he or she has the required skills and the ability to dedicate the time required to serve as a director in addition to other statutory requirements. A director who ceases to meet the statutory requirements for his or her appointment must immediately notify us of the same and his or her office will become vacated upon such notice.

Under our articles of association the approval of a special majority of the holders of at least 75% of the voting rights present and voting at a general meeting is generally required to remove any of our directors (other than the outside directors) from office. The holders of a majority of the voting power present and voting at a meeting may elect directors in their stead or fill any vacancy, however created, in our board of directors. In addition, vacancies on our board of directors, other than a vacancy in the office of an outside director, may be filled by a vote of a simple majority of the directors then in office. A director so chosen or appointed will hold office until the next annual general meeting of our shareholders, unless earlier removed by the vote of a majority of the directors then in office prior to such annual meeting. See “—Outside Directors” for a description of the procedure for election of outside directors.

Outside Directors

Qualifications of Outside Directors

The Companies Law requires companies incorporated under the laws of the State of Israel with shares listed on a stock exchange, including the NASDAQ Global Select Market, to appoint at least two outside directors. Our outside directors are Ms. Benjamini and Mr. Levy. Ms. Benjamini also serves as the lead independent director.

Outside directors are required to meet standards of independence and qualifications set forth in the Companies Law and related regulations. Among other independence qualifications, a person may not serve as an outside director if he is a relative of a controlling shareholder of a company, or if he or his affiliate (as defined in the Companies Law) has an employment, business or professional relationship or other affiliation (as defined in the Companies Law) with us.

In addition, the Companies Law requires every outside director appointed to the board of directors of an Israeli company to qualify as a “financial and accounting expert” or as “professionally competent,” as such terms are defined in the applicable regulations under the Companies Law, and at least one outside director must qualify as a “financial and accounting expert.” If at least one of our directors meets the independence requirements of the Exchange Act and the standards of the NASDAQ Stock Market rules for membership on the audit committee and also has financial and accounting expertise as defined in the Companies Law, then the other outside directors are only required to meet the professional qualifications requirement. Under applicable regulations, a director with financial and accounting expertise is a director who, through his or her education, professional experience and skill, has a high level of proficiency in and understanding of business accounting matters and financial statements. He or she must be able to thoroughly comprehend the financial statements of the company and initiate debate regarding the manner in which financial information is presented.

Election of Outside Directors

Outside directors are elected by a majority vote at a shareholders’ meeting, provided that either:

the majority of shares voted at the meeting, including at least a majority of the shares of non-controlling shareholder(s) and shareholders who do not have a personal interest in the election of the outside director (other than a personal interest that does not result from the shareholder's relationship with a controlling shareholder), voted at the meeting, excluding abstentions, vote in favor of the election of the outside director; or

the total number of shares of non-controlling shareholders and shareholders who do not have a personal interest in the election of the outside director (excluding a personal interest that does not result from the shareholder's relationship with a controlling shareholder) voted against the election of the outside director does not exceed two percent of the aggregate voting rights in the company.

The initial term of an outside director is three years, and he or she may be reelected to up to two additional terms of three years each at a shareholders’ meeting, subject to the voting threshold set forth above. Thereafter, an outside director may be reelected for additional periods of up to three years each, only if the company's audit committee and board of directors confirm that, in light of the outside director’s expertise and special contribution to the work of the board of directors and its committees, the reelection for such additional period is beneficial to the company. Outside directors may be removed by the same voting threshold as is required for their election, or by a court, and only if the outside directors cease to meet the statutory qualifications for their appointment or if they violate their duty of loyalty to the company. The tenure of outside directors, like all directors, may also be terminated by a court under limited circumstances. If the vacancy of an outside director position causes the company to have fewer than two outside directors, a company’s board of directors is required under the Companies Law to call a special general meeting of the company’s shareholders as soon as possible to appoint a new outside director. Each committee of a company’s board of directors which is authorized to exercise the board of directors’ authorities is required to include at least one outside director, except for the audit committee and the compensation committee, which are required to include all outside directors.

An outside director is entitled to compensation and reimbursement of expenses as provided in regulations promulgated under the Companies Law, and is otherwise prohibited from receiving any other compensation, directly or indirectly, in connection with services provided as an outside director, other than indemnification, exculpation and insurance as permitted pursuant to the Companies Law.

NASDAQ Requirements

Under the NASDAQ Stock Market rules, a majority of directors must meet the independence requirements specified in those rules. Our board of directors consists of seven members, six of whom are independent under the NASDAQ Stock Market rules. Specifically, our board has determined that Ms. Nurit Benjamini, Mr. Itzhak Danziger, Mr. Yigal Jacoby, Mr. Steven Levy, Mr. Miron Kenneth and Mr. Nadav Zohar meet the independence standards of the NASDAQ Stock Market rules. In reaching this conclusion, the board determined that none of these directors have a relationship that would preclude a finding of independence and that the other relationships that these directors have with us do not impair their independence. See “ITEM 16G. Corporate Governance” for additional information.

Audit Committee

Companies Law Requirements

Under the Companies Law, the board of directors of any public company must appoint an audit committee comprised of at least three directors, including all of the outside directors. The following persons may not be appointed as members of the audit committee:

the chairperson of the board of directors;

a controlling shareholder or a relative of a controlling shareholder (as defined in the Companies Law); or

any director who is engaged by, or provides services on a regular basis to the company, the company’s controlling shareholder or an entity controlled by a controlling shareholder or any director who generally relies on a controlling shareholder for his or her livelihood.

The Companies Law requires the majority of the audit committee members to be independent directors (as defined in the Companies Law), and the chairman of the audit committee is required to be an outside director. Any person disqualified from serving as a member of the audit committee may not be present at the audit committee meetings, unless the chairperson of the audit committee has determined that this person is required to be present for a particular matter. The Companies Law provides for certain other exclusions to this provision.

NASDAQ Requirements

Under the NASDAQ Stock Market rules, companies are required to maintain an audit committee consisting of at least three independent directors, all of whom are financially literate and one of whom has accounting or related financial management expertise. Our audit committee members are required to meet additional independence standards, including minimum standards set forth in rules of the SEC and adopted by the NASDAQ Stock Market.

Each of the members of our audit committee is “independent” under the relevant NASDAQ Stock Market rules and as defined in Rule 10A-3(b)(1) under the Exchange Act, which is different from the general test for independence of board and committee members.

Approval of Transactions with Related Parties

The approval of the audit committee is required to effect specified actions and transactions with office holders and controlling shareholders. The term “office holder” means a general manager, chief business manager, deputy general manager, vice general manager, or any other person assuming the responsibilities of any of the foregoing positions, without regard to such person’s title, as well as any director or manager directly subordinate to the general manager. The term “controlling shareholder” means a shareholder with the ability to direct the activities of the company, other than by virtue of being an office holder. A shareholder is presumed to be a controlling shareholder if the shareholder holds 50% or more of the voting rights in a company or has the right to appoint the majority of the directors of the company or its general manager. For the purpose of approving transactions with controlling shareholders, the term also includes any shareholder that holds 25% or more of the voting rights of the company, if the company has no shareholder that owns more than 50% of its voting rights. For purposes of determining the holding percentage stated above, two or more shareholders who have a personal interest in a transaction that is brought for the company’s approval are deemed as joint holders. The audit committee may not approve an action or a transaction with a controlling shareholder or with an office holder unless all the requirements of the Companies Law regarding the structure of the committee and the persons entitled to be present at meetings are met at the time of approval.

Audit Committee Role

Our board of directors has adopted an audit committee charter setting forth the responsibilities of the audit committee consistent with the rules of the SEC and the NASDAQ Stock Market, which include:

retaining and terminating the company’s independent auditors, subject to shareholder ratification;

pre-approval of audit and non-audit services provided by the independent auditors; and

approval of transactions with office holders and controlling shareholders, as described above, and other related-party transactions.

Additionally, under the Companies Law, the audit committee is responsible for: (a) identifying deficiencies in the management of a company’s business and making recommendations to the board of directors as to how to correct them; (b) reviewing and deciding whether to approve certain related party transactions and certain transactions involving conflicts of interest; (c) deciding whether certain actions involving conflicts of interest are material actions and whether certain related party transactions are extraordinary transactions; (d) reviewing the internal auditor’s work program; (e) examining the company’s internal control structure and processes, the performance of the internal auditor and whether the internal auditor has the tools and resources required to perform his or her duties; and (f) examining the independent auditor’s scope of work as well as the independent auditor’s fees, and providing the corporate body responsible for determining the independent auditor’s fees with its recommendations. In addition the audit committee is also be responsible for implementing procedures concerning employee complaints on improprieties in the administration of the company’s business and the protection to be provided to such employees. Furthermore, in accordance with regulations promulgated under the Companies Law, the audit committee discusses the draft financial statements and presents to the board its recommendations with respect to the draft financial statements. The audit committee charter states that in fulfilling this role the committee is entitled to rely on interviews and consultations with our management, our internal auditor and our independent auditor, and is not obligated to conduct any independent investigation or verification.

Our audit committee consists of Ms. Nurit Benjamini, Mr. Steven Levy and Mr. Miron Kenneth. The financial experts on the audit committee pursuant to the definition of the SEC are all members of the audit committee.

Compensation and Nominating Committee

Under the Companies Law, the compensation committee of a public company must consist of at least three directors who satisfy certain independence qualifications, including the additional independence requirements of the NASDAQ Stock Market rules applicable to the members of compensation committees, and the chairman of the compensation committee is required to be an outside director. We have established a compensation and nominating committee which currently consists of Ms. Nurit Benjamini, Mr. Steven Levy, and Mr. Miron Kenneth. The chairperson is Mr. Levy. This committee oversees matters related to our compensation policy and practices. Our board of directors has adopted a compensation and nominating committee charter setting forth the responsibilities of the committee consistent with the Companies Law and the NASDAQ Stock Market rules, which include:

approving, and recommending to the board of directors and the shareholders for their approval, the compensation of our Chief Executive Officer and other executive officers;

granting options and RSUs to our employees and the employees of our subsidiaries;

recommending candidates for nomination as members of our board of directors; and

developing and recommending to the board corporate governance guidelines and a code of business ethics and conduct in accordance with applicable laws.

The compensation committee is also authorized to retain and terminate compensation consultants, legal counsel or other advisors to the committee and to approve the engagement of any such consultant, counsel or advisor, to the extent it deems necessary or appropriate after specifically analyzing the independence of any such consultant retained by the committee.

On specified criteria, to review modifications to the compensation policy from time to time, to review its implementation and to approve the actual compensation terms of office holders prior to approval by the board of directors.

Internal Auditor

Under the Companies Law, the board of directors of a public company must appoint an internal auditor nominated by the audit committee. The role of the internal auditor is, among other things, to examine whether a company’s actions comply with applicable law and orderly business procedure. The internal auditor may be an employee of the company but not an interested party (as defined in the Companies Law), an office holder of the company, or a relative of an interested party or an office holder, among other restrictions. The firm of Deloitte Brightman Almagor Zohar is the internal auditor of the Company.

Exculpation, Insurance and Indemnification of Office Holders

Under the Companies Law, a company may not exculpate an office holder from liability for a breach of the duty of loyalty. However, a company may provide certain indemnification rights as detailed below and obtain insurance for an act performed in breach of the duty of loyalty of an office holder provided that the office holder acted in good faith, the act or its approval does not harm the company, and the office holder discloses the nature of his or her personal interest in the act and all material facts and documents a reasonable time before discussion of the approval. Our articles of association, in accordance with Israeli law, allow us to exculpate an office holder, in advance, from liability to us, in whole or in part, for damages caused to us as a result of a breach of duty of care. We may not exculpate a director for liability arising out of a prohibited dividend or distribution to shareholders or prohibited purchase of its securities.

In accordance with Israeli law, our articles of association allow us to indemnify an office holder in respect of certain liabilities either in advance of an event or following an event. Under Israeli law, an undertaking provided in advance by an Israeli company to indemnify an office holder with respect to a financial liability imposed on him or her in favor of another person pursuant to a judgment, settlement or arbitrator’s award approved by a court must be limited to events which in the opinion of the board of directors can be foreseen based on the company’s activities when the undertaking to indemnify is given, and to an amount or according to criteria determined by the board of directors as reasonable under the circumstances, and such undertaking must detail the above mentioned events and amount or criteria. Our articles of association allow us to undertake in advance to indemnify an office holder for, among other costs, reasonable litigation expenses, including attorneys’ fees, and certain financial liabilities and obligations, subject to certain restrictions pursuant to the Companies Law.

In accordance with Israeli law, our articles of association allow us to insure an office holder against certain liabilities incurred for acts performed as an office holder, including certain breaches of duty of loyalty to the company, a breach of duty of care to the company or to another person and certain financial liabilities and obligations imposed on the office holder.

We may not indemnify or insure an office holder against any of the following:

a breach of duty of loyalty, except to the extent that the office holder acted in good faith and had a reasonable basis to believe that the act would not prejudice the company;

a breach of duty of care committed intentionally or recklessly, excluding a breach arising out of the negligent conduct of the office holder;

an act or omission committed with intent to derive illegal personal benefit; or

a fine, civil fine, monetary sanction or forfeit levied against the office holder.

Under the Companies Law, exculpation, indemnification and insurance of office holders must be approved by our compensation committee and our board of directors and, in respect of our directors, the chief executive officer, and any employee or service provider who is considered a controlling shareholder, by our shareholders, provided that changes to existing arrangements may be approved by the audit committee if it approves that such changes are immaterial.

As of the date of this annual report, there are no claims for directors’ and officers’ liability insurance which have been filed in 2017 under our policies and we are not aware of any pending or threatened litigation or proceeding involving any of our directors or officers in which indemnification is sought.

We have entered into agreements with each of our directors and with certain of our office holders exculpating them, to the fullest extent permitted by law, from liability to us for damages caused to us as a result of a breach of duty of care, and undertaking to indemnify them to the fullest extent permitted by law. This indemnification is limited to events determined as foreseeable by the board of directors based on our activities, and to an amount or according to criteria determined by the board of directors as reasonable under the circumstances, and the insurance is subject to our discretion depending on its availability, effectiveness and cost. The current maximum amount set forth in such agreements is the greater of (1) with respect to indemnification in connection with a public offering of our securities, the gross proceeds raised by us and/or any selling shareholder in such public offering, and (2) with respect to all permitted indemnification, including a public offering of our securities, an amount equal to 50% of the our shareholders’ equity on a consolidated basis, based on our most recent financial statements made publicly available before the date on which the indemnity payment is made.

In the opinion of the SEC, indemnification of directors and office holders for liabilities arising under the Securities Act is against public policy and therefore unenforceable.

D. Employees

As of December 31, 2017, we had 477 employees of whom 260 were based in Israel, 114 in Europe, 17 in North America, 30 in Latin America and the remainder in Asia, Africa and Oceania. We have never experienced a work stoppage or a strike. The breakdown of our employees by department is as follows:

Under applicable Israeli law, we and our employees are subject to protective labor provisions such as restrictions on working hours, minimum wages, minimum vacation, sick pay, severance pay and advance notice of termination of employment as well as equal opportunity and anti-discrimination laws. Orders issued by the Israeli Ministry of Economy make certain industry-wide collective bargaining agreements applicable to us. These agreements affect matters such as cost of living adjustments to salaries, length of working hours and week, recuperation, travel expenses, and pension rights. Except as otherwise stated hereunder, our employees are not represented by a labor union. Under Spanish Labor law, we and our employees are subject to protective labor provisions and collective bargaining agreements, governing, among others, restrictions on working hours, minimum wages, minimum vacation, sick pay, severance pay and advance notice of termination of employment as well as equal opportunity and anti-discrimination laws. Our workers in our San Sebastian office in Spain, are represented by a worker’s representative, who will be subject to reelection during 2020. In addition, our employees in our Madrid office are represented by five workers representatives, who were recently elected for a term of four years and thus will be subject to reelection during 2021. Such representatives represent the employees with respect to labor health and prevention, training and equality.We provide our employees with benefits and working conditions which we believe are competitive with benefits and working conditions provided by similar companies. We have never experienced labor-related work stoppages and believe that our relations with our employees are good.

As used in this table, “beneficial ownership” is determined in accordance with the rules of the SEC and consists of either or both voting or investment power with respect to securities. For purposes of this table, a person is deemed to be the beneficial owner of securities that can be acquired within 60 days from March 1, 2018 through the exercise of any option or pursuant to vesting of RSU. Ordinary shares subject to options that are currently exercisable or exercisable within 60 days of March 1, 2018 and outstanding RSUs vesting within 60 days of March 1, 2018, are deemed outstanding for computing the ownership percentage of the person holding such options or RSUs, but are not deemed outstanding for the purpose of computing the ownership percentage of any other person. Except as otherwise indicated, the persons named in the table have reported that they have sole voting and sole investment power with respect to all ordinary shares shown as beneficially owned by them. The amounts and percentages are based upon 33,587,814 ordinary shares outstanding as of March 1, 2018 pursuant to Rule 13d-3(d)(1)(i) under the Exchange Act.

Our directors and executive officers hold, in the aggregate, 1,255,429 outstanding options and RSUs. The said amount includes options currently exercisable for 497,681 ordinary shares, as of March 1, 2018. The options (excluding RSUs) have a weighted average exercise price of $7.01 per share and have expiration dates until 2027.

“Option and RSU grants, net” is calculated by subtracting options and RSUs expired or forfeited.

As of March 1, 2018, we had 33,587,814 ordinary shares outstanding. We have adopted three share option plans. Under our share option plans, as of March 1, 2018, there were 2,816,708 outstanding options and RSUs, including options currently exercisable for 1,341,784 ordinary shares. As of March 1, 2018, 741,720 shares remained available for future grants under the 2016 Plan (as described below). Upon issuance, such ordinary shares may be freely sold in the public market, except for shares held by affiliates who have certain restrictions on their ability to sell. The options (excluding RSUs) have a weighted average exercise price of $7.61 per share.

We will only grant options, RSUs or other equity incentive awards under the 2016 Incentive Compensation Plan, although previously-granted options will continue to be governed by our other plans.

2016 Incentive Compensation Plan, as amended (formerly, 2006 Incentive Compensation Plan)

The Allot Communications Ltd. 2006 Incentive Compensation Plan (the “2006 Plan”) was adopted by the Board on October 29, 2006 and became effective immediately prior to the effective date of the Company’s IPO. Effective October 28, 2016, the Board of Directors of the Company amended and restated the 2006 Plan to extend the term of the 2006 Plan by ten years and to rename the 2006 Plan as the Allot Communications Ltd. 2016 Incentive Compensation Plan (the “2016 Plan”). The 2016 Plan will remain in effect, subject to the right of the Board of Directors to amend or terminate the 2016 Plan at any time pursuant to the terms of the 2016 Plan, until all shares reserved for issuance under the 2016 Plan shall have been delivered, and any restrictions on such shares shall have lapsed, provided that in no event may an award under the 2016 Plan be granted on or after October 27, 2026.

The 2016 Plan is intended to further our success by increasing the ownership interest of certain of our and our subsidiaries’ employees, directors and consultants and to enhance our and our subsidiaries’ ability to attract and retain employees, directors and consultants.

The number of ordinary shares that we may issue under the 2016 Plan will increase on the first day of each fiscal year during the term of the 2016 Plan, in each case in an amount equal to the lesser of (i) 1,000,000 shares, (ii) 3.5% of our outstanding ordinary shares on the last day of the immediately preceding year, or (iii) an amount determined by our board of directors. The number of shares subject to the 2016 Plan is also subject to adjustment if particular capital changes affect our share capital. Ordinary shares subject to outstanding awards under the 2016 Plan or our 2003 plan or 1997 plans that are subsequently forfeited or terminated for any other reason before being exercised will again be available for grant under the 2016 Plan. As of March 1, 2018, there were 2,816,708 outstanding options and RSUs under the 2016 Plan and 741,720 ordinary shares remained reserved for future grants under the 2016 Plan.

Israeli participants in the 2016 Plan may be granted options and/or restricted stock units subject to Section 102 of the Ordinance. Section 102 of the Ordinance, allows employees, directors and officers, who are not controlling shareholders and are considered Israeli residents to receive favorable tax treatment for compensation in the form of shares or options. Our non-employees service providers and controlling shareholders may only be granted options under another section of the Ordinance, which does not provide for similar tax benefits. Section 102 includes two alternatives for tax treatment involving the issuance of options or shares to a trustee for the benefit of the grantees and also includes an additional alternative for the issuance of options or shares directly to the grantee. The most favorable tax treatment for the grantees is under Section 102(b)(2) of the Ordinance, the issuance to a trustee under the “capital gain track.” However, under this track we are not allowed to deduct an expense with respect to the issuance of the options or shares. Any stock options granted under the 2016 Plan to participants in the United States will be either “incentive stock options,” which may be eligible for special tax treatment under the U.S. Internal Revenue Code of 1986, or options other than incentive stock options (referred to as “nonqualified stock options”), as determined by our compensation and nominating committee and stated in the option agreement.

Our compensation and nominating committee administers the 2016 Plan and it selects which of our and our subsidiaries’ and affiliates’ eligible employees, directors and/or consultants receive options, RSUs or other awards under the 2016 Plan and will determine the terms of the grant, including, exercise prices, method of payment, vesting schedules, acceleration of vesting and the other matters necessary in the administration of the plan.

If we undergo a change of control, as defined in the 2016 Plan, subject to any contrary law or rule, or the terms of any award agreement in effect before the change of control, (a) the compensation and nominating committee may, in its discretion, accelerate the vesting, exercisability and payment, as applicable, of outstanding options, RSUs and other awards; and (b) the compensation and nominating committee, in its discretion, may adjust outstanding awards by substituting ordinary shares or other securities of any successor or another party to the change of control transaction, or cash out outstanding options, RSUs and other awards, in any such case, generally based on the consideration received by our shareholders in the transaction.

ITEM 10: Additional Information

A. Share Capital

Not applicable.

B. Memorandum and Articles of Association

Memorandum and Articles of Association Incorporation

We are registered as a public company with the Israeli Registrar of Companies. Our registration number is 51-239477-6.

Objective

Our objectives under our memorandum of association are to engage in the business of computers, hardware and software, including without limitation research and development, marketing, consulting and the selling of knowledge, and any other activity which our board of directors shall determine.

Ordinary Shares

Our authorized share capital consists of 200,000,000 ordinary shares, par value ILS 0.10 per share. As of March 1, 2018, we had 33,587,814 ordinary shares outstanding. All outstanding ordinary shares are validly issued, fully paid and non-assessable. The rights attached to the ordinary shares are as follows:

Voting. Holders of our ordinary shares have one vote for each ordinary share held on all matters submitted to a vote of shareholders at a shareholder meeting. Shareholders may vote at shareholder meeting either in person, by proxy or by written ballot. Shareholder voting rights may be affected by the grant of any special voting rights to the holders of a class of shares with preferential rights that may be authorized in the future.

Transfer of Shares. Fully paid ordinary shares are issued in registered form and may be freely transferred under our articles of association unless the transfer is restricted or prohibited by another instrument, Israeli law or the rules of a stock exchange on which the shares are traded.

Election of Directors. Our ordinary shares do not have cumulative voting rights for the election of directors. Rather, under our articles of association our directors are elected by the holders of a simple majority of our ordinary shares at a general shareholder meeting. As a result, the holders of our ordinary shares that represent more than 50% of the voting power represented at a shareholder meeting have the power to elect any or all of our directors whose positions are being filled at that meeting, subject to the special approval requirements for outside directors. See “ITEM 6: Directors, Senior Management and Employees—Board Practices—Outside Directors.”

Dividend and Liquidation Rights. Under the Companies Law, shareholder approval is not required for the declaration of a dividend, unless the company’s articles of association provide otherwise. Our articles of association provide that our board of directors may declare and distribute a dividend to be paid to the holders of ordinary shares without shareholder approval in proportion to the paid up capital attributable to the shares that they hold. Dividends may be paid only out of profits legally available for distribution, as defined in the Companies Law, provided that there is no reasonable concern that the payment of a dividend will prevent us from satisfying our existing and foreseeable obligations as they become due. If we do not have profits legally available for distribution, we may seek the approval of the court to distribute a dividend. The court may approve our request if it is convinced that there is no reasonable concern that a payment of a dividend will prevent us from satisfying our existing and foreseeable obligations as they become due.

In the event of our liquidation, after satisfaction of liabilities to creditors, our assets will be distributed to the holders of ordinary shares in proportion to the paid up capital attributable to the shares that they hold. Dividend and liquidation rights may be affected by the grant of preferential dividend or distribution rights to the holders of a class of shares with preferential rights that may be authorized in the future.

Shareholder Meetings

We are required to convene an annual general meeting of our shareholders once every calendar year within a period of not more than 15 months following the preceding annual general meeting. Our board of directors may convene a special general meeting of our shareholders and is required to do so at the request of two directors or one quarter of the members of our board of directors or at the request of one or more holders of 5% or more of our share capital and 1% of our voting power or the holder or holders of 5% or more of our voting power. All shareholder meetings require prior notice of at least 21 days. The chairperson of our board of directors, or any other person appointed by the board of directors, presides over our general meetings. In the absence of the chairperson of the board of directors or such other person, one of the members of the board designated by a majority of the directors presides over the meeting. If no director is designated to preside as chairperson, then the shareholders present will choose one of the shareholders present to be chairperson. Subject to the provisions of the Companies Law and the regulations promulgated thereunder, shareholders entitled to participate and vote at general meetings are the shareholders of record on a date to be decided by the board of directors, which may be between four and 40 days prior to the date of the meeting.

Quorum

The quorum required for a meeting of shareholders consists of at least two shareholders present in person, by proxy or by written ballot, who hold or represent between them at least 25% of our voting power. A meeting adjourned for lack of a quorum generally is adjourned to the same day in the following week at the same time and place or any time and place as the directors designate in a notice to the shareholders. At the reconvened meeting, the required quorum consists of at least two shareholders present, in person, by proxy or by written ballot, who hold or represent between them at least 10% of our voting power, provided that if the meeting was initially called pursuant to a request by our shareholders, then the quorum required must include at least the number of shareholders entitled to call the meeting. See “— Shareholder Meetings.”

Resolutions

An ordinary resolution requires approval by the holders of a simple majority of the voting rights represented at the meeting, in person, by proxy or by written ballot, and voting on the resolution.

Under the Companies Law, unless otherwise provided in the articles of association or applicable law, all resolutions of the shareholders require a simple majority. A resolution for the voluntary winding up of the company requires the approval by holders of at least 75% of the voting rights represented at the meeting, in person, by proxy or by written ballot, and voting on the resolution. Under our articles of association (1) certain shareholders’ resolutions require the approval of a special majority of the holders of at least 75% of the voting rights represented at the meeting, in person, by proxy or by written ballot, and voting on the resolution, and (2) certain shareholders’ resolutions require the approval of a special majority of the holders of at least two-thirds of the voting securities of the company then outstanding.

Access to Corporate Records

Under the Companies Law, all shareholders generally have the right to review minutes of our general meetings, our shareholder register, including with respect to material shareholders, our articles of association, our financial statements and any document we are required by law to file publicly with the Israeli Companies Registrar. Any shareholder who specifies the purpose of its request may request to review any document in our possession that relates to any action or transaction with a related party which requires shareholder approval under the Companies Law. We may deny a request to review a document if we determine that the request was not made in good faith, that the document contains a commercial secret or a patent or that the document’s disclosure may otherwise impair our interests.

Fiduciary duties and approval of specified related party transactions under Israeli law

Fiduciary duties of office holders

The Companies Law imposes a duty of care and a duty of loyalty on all office holders of a company.

The duty of care of an office holder requires an office holder to act with the degree of proficiency with which a reasonable office holder in the same position would have acted under the same circumstances. The duty of care includes, among other things, a duty to use reasonable means, in light of the circumstances, to obtain certain information pertaining to the proposed action before the board of directors.

The duty of loyalty incumbent on an office holder requires him or her to act in good faith and for the benefit of the company, and includes, among other things, the duty to avoid conflicts of interest with the company, to refrain from competing with the company, and to disclose to the company information disclosed to him or her as a result of being an office holder.

We may approve an act specified above which would otherwise constitute a breach of the office holder’s duty of loyalty, provided that the office holder acted in good faith, the act or its approval does not harm the company, and the office holder discloses his or her personal interest a sufficient time before the approval of such act. Any such approval is subject to the terms of the Companies Law, setting forth, among other things, the organs of the company entitled to provide such approval, and the methods of obtaining such approval.

Disclosure of personal interests of an office holder and approval of acts and transactions

The Companies Law requires that an office holder promptly disclose to the company any personal interest that he or she may have relating to any existing or proposed transaction by the company (as well as certain information or documents). Once an office holder has disclosed his or her personal interest in a transaction, the approval of the appropriate organ(s) in the company is required in order to effect the transaction. However, a company may approve such a transaction or action only if it is in the best interests of the Company.

Disclosure of personal interests of a controlling shareholder and approval of transactions

Under the Companies Law, a controlling shareholder must also disclose any personal interest it may have in an existing or proposed transaction by the company. Transactions with controlling shareholders that are material, that are not in the ordinary course of business or that are not on market terms require approval by the audit committee, the board of directors and the shareholders of the company, and the Companies Law provides for certain quantitative requirements in respect of the voting of shareholders not having a personal interest in the applicable transaction.

Duties of shareholders

Under the Companies Law, a shareholder has a duty to refrain from abusing its power, to act in good faith and to act in an acceptable manner in exercising its rights and performing its obligations to the company and other shareholders. A shareholder also has a general duty to refrain from acting to the detriment of other shareholders.

In addition, any controlling shareholder or any shareholder having specific power with respect to a company (the power to appoint an office holder, or specific influence over a certain vote) is under a duty to act with fairness towards the company. The Companies Law does not describe the substance of this duty except to state that the remedies generally available upon a breach of contract will also apply in the event of a breach of the duty to act with fairness, taking the shareholder’s position in the company into account.

Approval of private placements

Under the Companies Law and the regulations promulgated thereunder, certain private placements of securities may require approval at a general meeting of the shareholders of a company. These include, for example, certain private placements completed in lieu of a special tender offer (See “Memorandum and Articles of Association—Acquisition under Israeli law”) or a private placement which qualifies as a related party transaction (See “Corporate governance practices—Fiduciary duties and approval of specified related party transactions under Israeli law”).

Acquisitions under Israeli Law

Full Tender Offer. A person wishing to acquire shares of a public Israeli company and who would as a result hold over 90% of the target company’s issued and outstanding share capital is required by the Companies Law to make a tender offer for the purchase of all of the issued and outstanding shares of the company. If the shareholders who do not accept the offer hold less than 5% of the issued and outstanding share capital of the company, and more than half of the offerees who do not have a personal interest in the tender offer accept the tender offer, all of the shares that the acquirer offered to purchase will be transferred to the acquirer by operation of law. Notwithstanding the above, if the shareholders who do not accept the offer hold less than 2% of the issued and outstanding share capital of the company or of the applicable class, the offer will nonetheless be accepted. However, a shareholder that had its shares so transferred may, within six months from the date of acceptance of the tender offer, petition the court to determine that the tender offer was for less than fair value and that the fair value should be paid as determined by the court. The bidder may provide in its tender offer that any accepting shareholder may not petition the court for fair value, but such condition will not be valid unless all of the information required under the Companies Law was provided prior to the acceptance date. The description above regarding a full tender offer also applies, with certain limitations, when a full tender offer for the purchase of all of the company’s securities is accepted.

Special Tender Offer. The Companies Law provides, subject to certain exceptions, that an acquisition of shares of a public Israeli company must be made by means of a “special tender offer” if, as a result of the acquisition, the purchaser would become a holder of at least 25% of the voting rights in the company. This rule does not apply if there is already another holder of at least 25% of the voting rights in the company. Similarly, the Companies Law provides that an acquisition of shares in a public company must be made by means of a tender offer if, as a result of the acquisition, the purchaser would become a holder of more than 45% of the voting rights in the company, and there is no other shareholder of the company who holds more than 45% of the voting rights in the company. The special tender offer may be consummated subject to certain majority requirements set forth in the Companies Law, and provided further that at least 5% of the voting rights attached to the company’s outstanding shares will be acquired by the party making the offer.

Merger. The Companies Law permits merger transactions between two Israeli companies if approved by each party’s board of directors and a certain percentage of each party’s shareholders. Following the approval of the board of directors of each of the merging companies, the boards must jointly prepare a merger proposal for submission to the Israeli Registrar of Companies.

Under the Companies Law, if the approval of a general meeting of the shareholders is required, merger transactions may be approved by the holders of a simple majority of our shares present, in person, by proxy or by written ballot, at a general meeting of the shareholders and voting on the transaction. In determining whether the required majority has approved the merger, if shares of the company are held by the other party to the merger, by any person holding at least 25% of the voting rights, or 25% of the means of appointing directors or the general manager of the other party to the merger, then a vote against the merger by holders of the majority of the shares present and voting, excluding shares held by the other party or by such person, or any person or entity acting on behalf of, related to or controlled by either of them, is sufficient to reject the merger transaction. In certain circumstances, a court may still approve the merger upon the request of holders of at least 25% of the voting rights of a company, if the court holds that the merger is fair and reasonable, taking into account the value of the parties to the merger and the consideration offered to the shareholders.

The Companies Law provides for certain requirements and procedures that each of the merging companies is to fulfill. In addition, a merger may not be completed unless at least fifty days have passed from the date that a proposal for approval of the merger was filed with the Israeli Registrar of Companies and thirty days from the date that shareholder approval of both merging companies was obtained.

Anti-Takeover Measures

Undesignated preferred shares. The Companies Law allows us to create and issue shares having rights different from those attached to our ordinary shares, including shares providing certain preferred or additional rights with respect to voting, distributions or other matters and shares having preemptive rights. We do not have any authorized or issued shares other than ordinary shares. In the future, if we do create and issue a class of shares other than ordinary shares, such class of shares, depending on the specific rights that may be attached to them, may delay or prevent a takeover or otherwise prevent our shareholders from realizing a potential premium over the market value of their ordinary shares. The authorization of a new class of shares will require an amendment to our articles of association which requires the prior approval of a simple majority of our shares represented and voted at a general meeting. In addition, we undertook towards the TASE that, as long as our shares are registered for trading with the TASE we will not issue or authorize shares of any class other than the class currently registered with the TASE, unless such issuance is in accordance with certain provisions of the Israeli Securities Law determining that a company registering its shares for trade on the TASE may not have more than one class of shares for a period of one year following registration with the TASE, and following such period the company is permitted to issue preferred shares if the preference of those shares is limited to a preference in the distribution of dividends and the preferred shares have no voting rights.

Supermajority voting. Our articles of association require the approval of the holders of at least two-thirds of our combined voting power to effect certain amendments to our articles of association.

Classified board of directors. Our articles of association provide for a classified board of directors. See “ITEM 6: Directors, Senior Management and Employees—Board Practices—Term of Directors.”

The transfer agent and registrar for our ordinary shares is American Stock Transfer & Trust Company. Its address is 6201 15th Avenue, Brooklyn, New York 11219, and its telephone number is (800) 937-5449.

C. Material Contracts

We have not been party to any material contracts within the two years prior to the date of this annual report, other than contracts entered into in the ordinary course of business, or as otherwise described below in this ITEM 10.C.

Material Contract		Location
Agreement with Flex (Israel) Ltd. and Amendment No. 1 thereto		“ITEM 4.B: Information on the Company–Business Overview–Manufacturing.”
Agreement with Optenet S.A		“ITEM 5.A: Operating and Financial Review and Prospects-Operating Results”
Non-Stabilized Lease Agreement		“ITEM 4: Information on Allot – D. Property, Plant and Equipment”

D. Exchange Controls

In 1998, Israeli currency control regulations were liberalized significantly, so that Israeli residents generally may freely deal in foreign currency and foreign assets, and non-residents may freely deal in Israeli currency and Israeli assets. There are currently no Israeli currency control restrictions on remittances of dividends on the ordinary shares or the proceeds from the sale of the shares provided that all taxes were paid or withheld; however, legislation remains in effect pursuant to which currency controls can be imposed by administrative action at any time.

Non-residents of Israel may freely hold and trade our securities. Neither our memorandum of association nor our articles of association nor the laws of the State of Israel restrict in any way the ownership or voting of ordinary shares by non-residents, except that such restrictions may exist with respect to citizens of countries which are in a state of war with Israel. Israeli residents are allowed to purchase our ordinary shares.

E. Taxation

Israeli Tax Considerations and Government Programs

The following is a general discussion only and is not exhaustive of all possible tax considerations. It is not intended, and should not be construed, as legal or professional tax advice and should not be relied upon for tax planning purposes. In addition, this discussion does not address all of the tax consequences that may be relevant to purchasers of our ordinary shares in light of their particular circumstances, or certain types of purchasers of our ordinary shares subject to special tax treatment. Examples of this kind of investor include residents of Israel and traders in securities who are subject to special tax regimes not covered in this discussion. Each individual/entity should consult its own tax or legal advisor as to the Israeli tax consequences of the purchase, ownership and disposition of our ordinary shares.

To the extent that part of the discussion is based on new tax legislation, which has not been subject to judicial or administrative interpretation, we cannot assure that the tax authorities or the courts will accept the views expressed in this section.

The following summary describes the current tax structure applicable to companies in Israel, with special reference to its effect on us. The following also contains a discussion of the material Israeli tax consequences to holders of our ordinary shares.

General Corporate Tax Structure in Israel

Israeli companies are generally subject to corporate tax. In 2017 and 2016, the corporate tax rate was 24% and 25%, respectively. The corporate tax rate for 2018 and thereafter is scheduled to be 23%. However, the effective tax rate payable by a company that derives income from an Approved Enterprise, a Benefited Enterprise, a Preferred Enterprise or a Technological Preferred Enterprise (as discussed below) may be considerably less. Capital gains derived by an Israeli company are generally subject to the prevailing corporate tax rate.

Tax Benefits and Grants for Research and Development

Israeli tax law allows, under certain conditions, a tax deduction for expenditures, including capital expenditures, for the year in which they are incurred. Expenditures are deemed related to scientific research and development projects, if:

The expenditures are approved by the relevant Israeli government ministry, determined by the field of research;

The research and development must be for the promotion of the company; and

The research and development is carried out by or on behalf of the company seeking such tax deduction.

The amount of such deductible expenses is reduced by the sum of any funds received through government grants for the finance of such scientific research and development projects. No deduction under these research and development deduction rules is allowed if such deduction is related to an expense invested in an asset depreciable under the general depreciation rules of the Ordinance. Expenditures from research and development that not so approved are deductible in equal amounts over three years, according to the Ordinance.

From time to time we may apply the Israel Innovation Authority for approval to allow a tax deduction for all research and development expenses during the year incurred. There can be no assurance that such application will be accepted.

Law for the Encouragement of Industry (Taxes), 1969

The Law for the Encouragement of Industry (Taxes), 1969, generally referred to as the Industry Encouragement Law, provides several tax benefits for industrial companies. We believe that we currently qualify as an “Industrial Company” within the meaning of the Industry Encouragement Law. The Industry Encouragement Law defines “Industrial Company” as a company resident in Israel, of which 90% or more of its income in any tax year, other than of income from defense loans, capital gains, interest and dividend, is derived from an “Industrial Enterprise which is located in Israel” owned by it. An “Industrial Enterprise” is defined as an enterprise whose major activity in a given tax year is industrial production activity.

The following corporate tax benefits, among others, are available to Industrial Companies:

Amortization of the cost of purchased know-how and patents and of rights to use a patent and know-how which are used for the development or advancement of the company, over an eight-year period;

Under specified conditions, an election to file consolidated tax returns with additional related Israeli Industrial Companies; and

Expenses related to a public offering in Israel and in recognized stock markets, are deductible in equal amounts over three years.

Under certain tax laws and regulations, an “Industrial Enterprise” may be eligible for special depreciation rates for machinery, equipment and buildings. These rates differ based on various factors, including the date the operations begin and the number of work shifts. An “Industrial Company” owning an approved enterprise may choose between these special depreciation rates and the depreciation rates available to the approved enterprise.

Eligibility for the benefits under the Industry Encouragement Law is not subject to receipt of prior approval from any governmental authority. We can give no assurance that we qualify or will continue to qualify as an “Industrial Company” or that the benefits described above will be available in the future.

Israeli Transfer Pricing Regulations

On November 29, 2006, the Income Tax Regulations (Determination of Market Terms), 2006, promulgated under Section 85A of the Ordinance, came into effect (the “TP Regulations”). Section 85A of the Ordinance and the TP Regulations generally require that all cross-border transactions carried out between related parties be conducted on an arm’s length basis and be taxed accordingly. The TP Regulations did not have a material effect on us.

Tax Benefits under the Law for Encouragement of Capital Investments, 1959

Tax Benefits Prior to the 2005 Amendment

The Law for the Encouragement of Capital Investments, 1959, as amended, generally referred to as the Investments Law, provides that a proposed capital investment in eligible facilities may, upon application to the Investment Center of the Ministry of Industry and Commerce of the State of Israel, be designated as an “Approved Enterprise.”

The Investments Law provides that an approved enterprise is eligible for tax benefits on taxable income derived from its approved enterprise programs. The tax benefits under the Investments Law also apply to income generated by a company from the grant of a usage right with respect to know-how developed by the Approved Enterprise, income generated from royalties, and income derived from a service which is auxiliary to such usage right or royalties, provided that such income is generated within the Approved Enterprise’s ordinary course of business. The tax benefits under the Investments Law are not, generally, available with respect to income derived from products manufactured outside of Israel. In addition, the tax benefits available to an Approved Enterprise are contingent upon the fulfillment of conditions stipulated in the Investments Law and regulations and the criteria set forth in the specific certificate of approval, as described above. In the event that a company does not meet these conditions, it would be required to refund the amount of tax benefits, plus a consumer price index linkage adjustment and interest.

The Investments Law also provides that an Approved Enterprise is entitled to accelerated depreciation on its property and equipment that are included in an Approved Enterprise program in the first five years of using the equipment.

Should we derive income from sources other than the Approved Enterprise during the relevant period of benefits, such income will be taxable at the regular corporate tax rates.

Under certain circumstances (as further detailed below), the benefit period may extend to a maximum of ten years from the commencement of the benefit period.

A company may elect to receive an alternative package of benefits. Under the alternative package of benefits, a company’s undistributed income derived from the Approved Enterprise will be exempt from corporate tax for a period of between two and ten years from the first year the company derives taxable income under the program, after the commencement of production, depending on the geographic location of the Approved Enterprise within Israel, and such company will be eligible for a reduced tax rate for the remainder of the benefits period.

A company that has elected the alternative package of benefits, such as us, that subsequently pays a dividend out of income derived from the approved enterprise(s) during the tax exemption period will be subject to corporate tax in the year the dividend is distributed in respect of the gross amount distributed, at the rate which would have been applicable had the company not elected the alternative package of benefits, (generally 10%-25%, depending on the percentage of the company’s ordinary shares held by foreign shareholders). The dividend recipient is subject to withholding tax at the reduced rate of 15% applicable to dividends from approved enterprises, if the dividend is distributed during the tax exemption period or within twelve years thereafter. In the event, however, that the company qualifies as a foreign investors’ company, there is no such time limitation.

As of December 31, 2017, we believe that we met the aforementioned conditions.

Foreign Investors' Company (“FIC”)

A company that has an Approved Enterprise program is eligible for further tax benefits if it qualifies as a foreign investors’ company. A foreign investors’ company is a company of which, among other criteria, more than 25% of its share capital and combined share and loan capital is owned by non-Israeli residents. A company that qualifies as a foreign investors’ company and has an approved enterprise program is eligible for tax benefits for a ten-year benefit period.

Subject to applicable provisions concerning income under the alternative package of benefits, dividends paid by a company are considered to be attributable to income received from the entire company and the company’s effective tax rate is the result of a weighted average of the various applicable tax rates, excluding any tax-exempt income. Under the Investments Law, a company that has elected the alternative package of benefits is not obliged to distribute retained profits, and may generally decide from which year’s profits to declare dividends.

In 1998, the production facilities of the Company related to its computational technologies were granted the status of an “Approved Enterprise” under the Law. In 2004, an expansion program was granted the status of “Approved Enterprise.” According to the provisions of the Law, the Company has elected the alternative package of benefits and has waived Government grants in return for tax benefits.

Tax Benefits under the 2005 Amendment

An amendment to the Investments Law, generally referred as the 2005 Amendment, effective as of April 1, 2005 has significantly changed the provisions of the Investments Law. The amendment includes revisions to the criteria for investments qualified to receive tax benefits as an Approved Enterprise.

The 2005 Amendment simplifies the approval process for the approved enterprise. According to the 2005 Amendment, only approved enterprises receiving cash grants require the approval of the Investment Center.

As a result of the 2005 Amendment, it is no longer necessary for a company to acquire Approved Enterprise status in order to receive the tax benefits previously available under the Alternative Route, and therefore such companies need not apply to the Investment Center for this purpose. Rather, a company may claim the tax benefits offered by the Investments Law directly in its tax returns or by notifying the Israeli Tax Authority within twelve months of the end of that year, provided that its facilities meet the criteria for tax benefits set out by the 2005 Amendment. Such enterprise is referred to as the Benefited Enterprise. Companies are also granted a right to approach the Israeli Tax Authority for a pre-ruling regarding their eligibility for benefits under the 2005 Amendment. Tax benefits are available under the 2005 Amendment to production facilities (or other eligible facilities), which are generally required to derive more than 25% of their business income from export. In order to receive the tax benefits, the 2005 Amendment states that a company must make an investment in the Benefited Enterprise exceeding a certain percentage or a minimum amount specified in the Investments Law.

The duration of tax benefits is subject to a limitation of the earlier of seven to ten years from the Commencement Year, or twelve years from the first day of the Year of Election. The Commencement Year is defined as the later of (a) the first tax year in which a company had derived income for tax purposes from the Beneficiary Enterprise or (b) the year in which a company requested to have the tax benefits apply to the Beneficiary Enterprise – Year of Election. The tax benefits granted to a Benefited Enterprise are determined, as applicable to its geographic location within Israel, according to one of the following tax routes, which may be applicable to us:

Similar to the aforementioned alternative route, exemption from corporate tax on undistributed income for a period of two to ten years, depending on the geographic location of the Benefited Enterprise within Israel, and a reduced corporate tax rate of 10% to 25% for the remainder of the benefits period, depending on the level of foreign investment in each year. Benefits may be granted for a term of seven to ten years, depending on the level of foreign investment in the company. If the company pays a dividend out of income derived from the Benefited Enterprise during the tax exemption period, such income will be subject to corporate tax at the applicable rate (10%-25%) in respect of the gross amount of the dividend that may be distributed. The company is required to withhold tax at the source at a rate of 15% from any dividends distributed from income derived from the Benefited Enterprise; and

A special tax route, which enables companies owning facilities in certain geographical locations in Israel to pay corporate tax at the rate of 11.5% on income of the Benefited Enterprise. The benefits period is ten years. Upon payment of dividends, the company is required to withhold tax at source at a rate of 15% for Israeli residents and at a rate of 4% for foreign residents.

Generally, a company that is Abundant in Foreign Investment (owned by at least 74% foreign shareholders and has undertaken to invest a minimum sum of $20 million in the Benefited Enterprise as defined in the Investments Law) is entitled to an extension of the benefits period by an additional five years, depending on the rate of its income that is derived in foreign currency.

The 2005 Amendment changes the definition of “foreign investment” in the Investments Law so that the definition requires a minimal investment of ILS 5.0 million by foreign investors. Furthermore, such definition also includes the purchase of shares of a company from another shareholder, provided that the company’s outstanding and paid-up share capital exceeds ILS 5.0 million. Such changes to the aforementioned definition took effect retroactively from 2003.

As a result of the 2005 Amendment, tax-exempt income generated under the provisions of the Investments Law, as amended, will subject us to taxes upon distribution or liquidation and we may be required to record deferred tax liability with respect to such tax-exempt income.

We elected the years of 2006 and 2009 as “year of election” under the Investments Law after the 2005 Amendment.

We expect that a substantial portion of any taxable operating income that we may realize in the future will be derived from our approved enterprise status.

As of December 31, 2017, we did not generate exempt income under the provisions of the Investments Law.

Tax Benefits under the 2011 Amendment

As of January 1, 2011 new legislation amending the Investment Law came into effect (the “2011 Amendment”). The 2011 Amendment introduced a new status of “Preferred Company” and “Preferred Enterprise”, replacing the then existing status of “Benefited Company” and “Benefited Enterprise”. Similar to a “Benefited Company”, a Preferred Company is an industrial company owning a Preferred Enterprise which meets certain conditions (including a minimum threshold of 25% export). However, under this legislation the requirement for a minimum investment in productive assets was cancelled.

Under the 2011 Amendment, a uniform corporate tax rate applies to all qualifying income of the Preferred Company, as opposed to the former law, which was limited to income from the Approved Enterprises and Benefited Enterprise during the benefits period. The uniform corporate tax rate was 9% in areas in Israel designated as Development Zone A and 16% elsewhere in Israel during 2015 and 2016, an amendment to the Investment law from December 2016 reduced the tax rate in Development Zone A to 7.5% starting from 2017 while the tax rate in other areas remains 16%.

A dividend distributed from income which is attributed to a Preferred Enterprise will be subject to withholding tax at source at the following rates: (i) Israeli resident corporation –0%, (ii) Israeli resident individual – 20% in 2014 and onwards (iii) non-Israeli resident - 20% in 2014 and onwards, subject to a reduced tax rate under the provisions of an applicable double tax treaty.

The provisions of the 2011 Amendment also provided transitional provisions to address companies already enjoying current benefits. Under the transition provisions of the new legislation, a company may decide to irrevocably implement the 2011 Amendment while waiving benefits provided under the Investment Law prior to the 2011 Amendment; or to remain subject to the Investment Law prior to the 2011 Amendment. We have examined the possible effect, if any, of these provisions of the 2011 Amendment on our financial statements and have decided, at this time, not to opt to apply the new benefits under the 2011 Amendment.

Tax Benefits under the 2016 Amendment

In December 2016 new legislation amended the Investment Law (the “2016 Amendment”). Under the 2016 Amendment a new status of “Technological Preferred Enterprise” was introduced to the Investment Law.

Under the 2016 Amendment two new tracks are available:

Technological Preferred Enterprise – an enterprise which is part of a consolidated group with consolidated annual revenues of less than ILS 10 billion. A Technological Preferred Enterprise which is located in areas other than Development Zone A will be subject to tax at a rate of 12% on profits derived from intellectual property, and a Technological Preferred Enterprise in Development Zone A will be subject to tax at a rate of 7.5%; and

Special Technological Preferred Enterprise – an enterprise which is part of a consolidated group with consolidated annual revenues exceeding ILS 10 billion. Such an enterprise will be subject to tax at a rate of 6% on profits derived from intellectual property regardless of the enterprise’s geographical location.

Any dividends distributed to foreign companies, as defined in the Investment law, derived from income from the Technological Preferred Enterprise will be subject to tax at a rate of 20% (which may be reduced by a an applicable double tax treaty, or a lower rate of 4% in case 90% or more of the Preferred Technological Enterprise’s shares are held by foreign corporations.

The regulations implementing the above new tracks were published on May 28, 2017 and are effective as of January 1, 2017. We have examined the possible effect, if any, of these provisions of the 2016 Amendment on our financial statements and have decided, at this time, not to opt to apply the new benefits under the 2016 Amendment.

Special Provisions Relating to Tax Reporting in United States Dollars

Under the Income Tax (Inflationary Adjustments) Law, 1985, results for tax purposes are measured in real terms, in accordance with the changes in the Israeli Consumer Price Index (“Israeli CPI”). Accordingly, until 2011, results for tax purposes were measured in terms of earnings in ILS after certain adjustments for increases in the Israeli CPI. Commencing in the taxable year 2012, we have elected to measure our taxable income and file our tax return in United States Dollars, under the Israeli Income Tax Regulations (Principles Regarding the Management of Books of Account of Foreign Invested Companies and Certain Partnerships and the Determination of Their Taxable Income), 1986.

Capital Gains Tax on Sales of Our Ordinary Shares

Israeli law generally imposes a capital gains tax on the sale of any capital assets by residents of Israel, as defined for Israeli tax purposes, and on the sale of assets located in Israel, including shares in Israeli companies, by both residents and non-residents of Israel, unless a specific exemption is available or a tax treaty between Israel and the shareholder’s country of residence provides otherwise. The law distinguishes between real gain and inflationary surplus. The inflationary surplus is a portion of the total capital gain which is equivalent to the increase of the relevant asset’s purchase price which is attributable to the increase in the Israeli consumer price index or, in certain circumstances, a foreign currency exchange rate, between the date of purchase and the date of sale. The real gain is the excess of the total capital gain over the inflationary surplus.

As of January 1, 2012, the tax rate applicable to capital gains derived from the sale of shares, whether listed on a stock market or not, is 25% for Israeli individuals, unless such shareholder claims a deduction for financing expenses in connection with such shares, in which case the gain is generally taxed at a rate of 30%. Additionally, if such shareholder is considered a “material shareholder” at any time during the 12-month period preceding such sale, i.e., such shareholder holds directly or indirectly, including with others, at least 10% of any means of control in a company, the tax rate is 30%. Israeli companies are subject to the Corporate Tax rate on capital gains derived from the sale of shares. However, the foregoing tax rates do not apply to: (i) dealers in securities; and (ii) shareholders who acquired their shares prior to an initial public offering (that may be subject to a different tax arrangement).

The tax basis of shares acquired prior to January 1, 2003 is determined in accordance with the average closing share price in the three trading days preceding January 1, 2003. However, a request may be made to the tax authorities to consider the actual adjusted cost of the shares as the tax basis if it is higher than such average price.

In addition, as of January 1, 2013, shareholders that are individuals who have taxable income that exceeds ILS 800,000 in a tax year (linked to the CPI each year - ILS 803,520 in 2016), will be subject to an additional tax, referred to as High Income Tax, at the rate of 2% on their taxable income for such tax year which is in excess of such amount. Starting from January 1, 2017, the High Income tax rate has increased to 3% and its threshold has been lowered to 640,000 ILS. For this purpose taxable income will include taxable capital gains from the sale of our shares and taxable income from dividend distributions.

Non-Israeli residents are exempt from Israeli capital gains tax on any gains derived from the sale of shares of Israeli companies publicly traded on a recognized stock exchange or regulated market outside of Israel, provided that such capital gains are not derived from a permanent establishment in Israel, the shareholders are not subject to the Adjustments Law, and the shareholders did not acquire their shares prior to an initial public offering. However, non-Israeli corporations will not be entitled to such exemption if Israeli residents (i) have a controlling interest of more than 25% in such non-Israeli corporation, or (ii) are the beneficiaries or are entitled to 25% or more of the revenues or profits of such non-Israeli corporation, whether directly or indirectly.

In some instances where our shareholders may be liable to Israeli tax on the sale of their ordinary shares, the payment of the consideration may be subject to the withholding of Israeli tax at the source.

Pursuant to the Convention between the government of the United States and the government of Israel with respect to taxes on income, as amended (the “U.S.-Israel Tax Treaty”), the sale, exchange or disposition of ordinary shares by a person who (i) holds the ordinary shares as a capital asset, (ii) qualifies as a resident of the United States within the meaning of the U.S.-Israel Tax Treaty and (iii) is entitled to claim the benefits afforded to such person by the U.S.-Israel Tax Treaty, generally, will not be subject to the Israeli capital gains tax. Such exemption will not apply if (i) such U.S. resident holds, directly or indirectly, shares representing 10% or more of our voting power during any part of the 12-month period preceding such sale, exchange or disposition, subject to certain conditions, or (ii) the capital gains from such sale, exchange or disposition can be allocated to a permanent establishment in Israel. In such case, the sale, exchange or disposition of ordinary shares would be subject to Israeli tax, to the extent applicable; however, under the U.S.-Israel Tax Treaty, such U.S. resident would be permitted to claim a credit for such taxes against the U.S. federal income tax imposed with respect to such sale, exchange or disposition, subject to the limitations in U.S. laws applicable to foreign tax credits. The U.S.-Israel Tax Treaty does not relate to U.S. state or local taxes.

Taxation of Dividends paid to Non-Resident Holders of Shares

Non-residents of Israel are subject to income tax on income accrued or derived from sources in Israel. Such sources of income include passive income such as dividends. On distributions of dividends other than bonus shares, or stock dividends, income tax is applicable at the rate of 25%, or 30% for a shareholder that is considered a “material shareholder” at any time during the 12-month period preceding such distribution, unless a different rate is provided in a treaty between Israel and the shareholder’s country of residence. However, under the Investments Law, dividends generated by an Approved Enterprise, Privileged Enterprise, Preferred Enterprise or Technological Preferred Enterprise may be are taxed at a different rate s discussed above.

Under the U.S.-Israel Tax Treaty, the maximum tax on dividends paid to a holder of ordinary shares that is a Treaty U.S. Resident is 25%. However, if the income out of which the dividend is paid is not generated by an Approved Enterprise, Privileged Enterprise, Preferred Enterprise or Technological Preferred Enterprise, and not more than 25% of our gross income consists of interest or dividends, dividends paid to a U.S. corporation holding at least 10% of our issued voting power during the part of the tax year which precedes the date of payment of the dividend and during the whole of its prior tax year are generally taxed at a rate of 12.5%.

United States Federal Income Taxation

The following is a description of the material United States federal income tax consequences of the ownership and disposition of our ordinary shares. This description addresses only the United States federal income tax considerations of holders that hold such ordinary shares as capital assets. This description does not address tax considerations applicable to holders that may be subject to special tax rules, including:

financial institutions or insurance companies;

real estate investment trusts, regulated investment companies or grantor trusts;

dealers or traders in securities or currencies;

tax-exempt entities;

certain former citizens or long-term residents of the United States;

persons that will hold our shares through a partnership or other pass-through entity;

persons that received our shares as compensation for the performance of services;

persons that will hold our shares as part of a “hedging” or “conversion” transaction or as a position in a “straddle” for United States federal income tax purposes;

persons whose “functional currency” is not the United States dollar; or

holders that own directly, indirectly or through attribution 10.0% or more of the voting power or value of our shares.

Moreover, this description does not address the United States federal estate and gift or alternative minimum tax consequences of the ownership and disposition of our ordinary shares.

This description is based on the U.S. Internal Revenue Code of 1986, as amended, existing, proposed and temporary United States Treasury Regulations and judicial and administrative interpretations thereof, in each case as in effect and available on the date hereof. All of the foregoing are subject to change, which change could apply retroactively and could affect the tax consequences described below.

For purposes of this description, a “U.S. Holder” is a beneficial owner of our ordinary shares that, for United States federal income tax purposes, is:

a citizen or individual resident of the United States;

corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any state thereof, including the District of Columbia;

an estate the income of which is subject to United States federal income taxation regardless of its source; or

a trust if such trust has validly elected to be treated as a United States person for United States federal income tax purposes or if (1) a court within the United States is able to exercise primary supervision over its administration and (2) one or more United States persons have the authority to control all of the substantial decisions of such trust.

A “Non-U.S. Holder” is a beneficial owner of our ordinary shares that is neither a U.S. Holder nor a partnership (or other entity treated as a partnership for United States federal income tax purposes).

If a partnership (or any other entity treated as a partnership for United States federal income tax purposes) holds our ordinary shares, the tax treatment of a partner in such partnership will generally depend on the status of the partner and the activities of the partnership. Such a partner or partnership should consult its tax advisor as to its tax consequences.

You should consult your tax advisor with respect to the United States federal, state, local and foreign tax consequences of owning and disposing of our ordinary shares.

Distributions

Subject to the discussion below under “Passive Foreign Investment Company Considerations,” if you are a U.S. Holder, for United States federal income tax purposes, the gross amount of any distribution made to you, with respect to our ordinary shares before reduction of any Israeli taxes withheld therefrom, other than certain distributions, if any, of our ordinary shares distribute pro rata to all our shareholders, will be includible in your income as dividend income to the extent such distribution is paid out of our current or accumulated earnings and profits as determined under United States federal income tax principles. Subject to the discussion below under “Passive Foreign Investment Company Considerations,” non-corporate U.S. Holders may qualify for the lower rates of taxation with respect to dividends on ordinary shares applicable to long-term capital gains (that is, gains from the sale of capital assets held for more than one year), provided that certain conditions are met, including certain holding period requirements and the absence of certain risk reduction transactions. However, such dividends will not be eligible for the dividends received deduction generally allowed to corporate U.S. Holders. Subject to the discussion below under “Passive Foreign Investment Company Considerations,” to the extent, if any, that the amount of any distribution by us exceeds our current and accumulated earnings and profits as determined under United States federal income tax principles, it will be treated first as a tax-free return of your adjusted tax basis in our ordinary shares and thereafter as capital gain. We do not expect to maintain calculations of our earnings and profits under United States federal income tax principles and, therefore, if you are a U.S. Holder you should expect that the entire amount of any distribution generally will be reported as dividend income to you.

If you are a U.S. Holder, dividends paid to you with respect to your ordinary shares will be treated as foreign source income, which may be relevant in calculating your foreign tax credit limitation. Subject to certain conditions and limitations, Israeli tax withheld on dividends may be deducted from your taxable income or credited against your United States federal income tax liability. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividends that we distribute generally should constitute “passive category income,” or, in the case of certain U.S. Holders, “general category income.” A foreign tax credit for foreign taxes imposed on distributions may be denied when you do not satisfy certain minimum holding period requirements. In addition, for periods in which we are a “United Stated-owned foreign corporation”, a portion of dividends paid by us may be treated as U.S. source solely for purposes of the foreign tax credit. We would be treated as a United States-owned foreign corporation if 50% or more of the total value or total voting power of our stock is owned, directly, indirectly or by attribution, by United States persons. To the extent any portion of our dividends is treated as U.S. source income pursuant to this rule, the ability of a U.S. Holder to claim a foreign tax credit for any Israeli withholding taxes payable in respect of our dividends may be limited. A U.S. Holder entitled to benefits under the United States-Israel Tax Treaty may, however, elect to treat any dividends as foreign source income for foreign tax credit purposes if the dividend income is separated from other income items for purposes of calculating the U.S. Holder’s foreign tax credit. The rules relating to the determination of the foreign tax credit are complex, and you should consult your personal tax advisors to determine whether and to what extent you would be entitled to this credit.

Subject to the discussion below under “Backup Withholding Tax and Information Reporting Requirements,” if you are a Non-U.S. Holder, you generally will not be subject to United States federal income or withholding tax on dividends received by you on your ordinary shares, unless you conduct a trade or business in the United States and such income is effectively connected with that trade or business.(or, if required by an applicable income tax treaty, the dividends are attributable to a permanent establishment that such holder maintains in the United States).

Sales Exchange or other Disposition of Ordinary Shares

Subject to the discussion below under “Passive Foreign Investment Company Considerations,” if you are a U.S. Holder, you generally will recognize gain or loss on the sale, exchange or other disposition of our ordinary shares equal to the difference between the amount realized on such sale, exchange or other disposition and your adjusted tax basis in our ordinary shares. Such gain or loss will be capital gain or loss. If you are a non-corporate U.S. Holder, capital gain from the sale, exchange or other disposition of ordinary shares is eligible for the preferential rate of taxation applicable to long-term capital gains if your holding period for such ordinary shares exceeds one year (that is, such gain is long-term capital gain). Gain or loss, if any, recognized by you generally will be treated as United States source income or loss for United States foreign tax credit purposes. The deductibility of capital losses for U.S. federal income tax purposes is subject to limitations.

such gain is effectively connected with your conduct of a trade or business in the United States (or, if required by an applicable income tax treaty, the gain is attributable to a permanent establishment that you maintain in the United States); or

you are an individual and have been present in the United States for 183 days or more in the taxable year of such sale or exchange and certain other conditions are met.

Passive Foreign Investment Company Considerations

A non-U.S. corporation will be classified as a “passive foreign investment company,” or a PFIC, for United States federal income tax purposes in any taxable year in which, after applying certain look-through rules, either:

at least 75 percent of its gross income is "passive income"; or

at least 50 percent of the average value of its gross assets (based on the quarterly value of such gross assets) is attributable to assets that produce “passive income” or are held for the production of passive income.

Passive income for this purpose generally includes dividends, interest, royalties, rents, gains from commodities and securities transactions and the excess of gains over losses from the disposition of assets which produce passive income.

PFIC status is an annual determination that is based on tests which are factual in nature and our status in future years will depend on our income, assets and activities in each of those years. Therefore there can be no assurance that we will not be considered a PFIC for any taxable year. While public companies often employ a market capitalization method to value their assets, the IRS has not issued guidance concerning how to value a foreign public company’s assets for PFIC purposes. The market price of our ordinary shares is likely to fluctuate and the market price of the shares of technology companies has been especially volatile. In certain circumstances, including volatile market conditions, it may be appropriate to employ alternative methods to more accurately determine the fair market value of our assets other than the market capitalization method. Given the volatility of the capital markets in recent years, we have obtained an independent valuation of our company for the 2017 tax year, as well as an opinion from a U.S. tax advisor that, applying the results of the independent valuation of our company which employed an approach other than the market capitalization approach, and which provided the reasoning underlying the use of such approach, we should not be a PFIC for the 2017 taxable year. We considered such valuation in determining the value of our total assets and we also considered the above-referenced opinion. On that basis, we believe that we were not a PFIC for the 2017 tax year. However there can be no certainty that the IRS will not challenge such a position and determine that based on the IRS’s interpretation of the asset test, we were a PFIC for the 2017 tax year. If we were a PFIC, and you are a U.S. Holder, you generally would be subject to ordinary income tax rates, imputed interest charges and other disadvantageous tax treatment (including the denial of the taxation of such dividends at the lower rates applicable to long-term capital gains, as discussed above under “–Distributions”) with respect to any gain from the sale, exchange or other disposition of, and certain distributions with respect to, your ordinary shares. A U.S. Holder should consult his, her or its own tax advisor with respect to the potential application of the PFIC rules in his, her or its particular circumstances.

Because the market price of our ordinary shares is likely to fluctuate and the market price of the shares of technology companies has been especially volatile, and because that market price may affect the determination of whether we will be considered a PFIC, we cannot assure you that we will not be considered a PFIC for any taxable year.

Under the PFIC rules, unless a U.S. Holder makes one of the elections described in the next paragraphs, a special tax regime will apply to both (a) any “excess distribution” by us (generally, the U.S. Holder’s ratable portion of distributions in any year which are greater than 125% of the average annual distribution received by such U.S. Holder in the shorter of the three preceding years or the U.S. Holder’s holding period) and (b) any gain realized on the sale or other disposition of the ordinary shares. Under this regime, any excess distribution and realized gain will be treated as ordinary income and will be subject to tax as if (a) the excess distribution or gain had been realized ratably over the U.S. Holder’s holding period, (b) the amount deemed realized had been subject to tax in each year of that holding period, and (c) the interest charge generally applicable to underpayments of tax had been imposed on the taxes deemed to have been payable in those years. In addition, dividend distributions made to you will not qualify for the lower rates of taxation applicable to long term capital gains discussed above under “Distributions.”

Certain elections are available to U.S. Holders of shares that may serve to alleviate some of the adverse tax consequences of PFIC status. If we agreed to provide the necessary information, you could avoid the interest charge imposed by the PFIC rules by making a qualified electing fund, or a QEF election, which election may be made retroactively under certain circumstances, in which case you generally would be required to include in income on a current basis your pro rata share of our ordinary earnings as ordinary income and your pro rata share of our net capital gains as long-term capital gain. We do not expect to provide to U.S. Holders the information needed to report income and gain pursuant to a QEF election, and we make no undertaking to provide such information in the event that we are a PFIC.

Under an alternative tax regime, you may also avoid certain adverse tax consequences relating to PFIC status discussed above by making a mark-to-market election with respect to our ordinary shares annually, provided that the shares are “marketable.” Shares will be marketable if they are regularly traded on certain U.S. stock exchanges (including NASDAQ) or on certain non-U.S. stock exchanges. For these purposes, the shares will generally be considered regularly traded during any calendar year during which they are traded, other than in negligible quantities, on at least fifteen days during each calendar quarter.

If you choose to make a mark-to-market election, you would recognize as ordinary income or loss each year an amount equal to the difference as of the close of the taxable year between the fair market value of the PFIC shares and your adjusted tax basis in the PFIC shares. Losses would be allowed only to the extent of net mark-to-market gain previously included by you under the election for prior taxable years. If the mark-to-market election were made, then the PFIC rules set forth above relating to excess distributions and realized gains would not apply for periods covered by the election. If you make a mark-to-market election after the beginning of your holding period of our ordinary shares, you would be subject to interest charges with respect to the inclusion of ordinary income attributable to the period before the effective date of such election.

Under certain circumstances, ordinary shares owned by a Non-U.S. Holder may be attributed to a U.S. person owning an interest, directly or indirectly, in the Non-U.S. Holder. In this event, distributions and other transactions in respect of such ordinary shares may be treated as excess distributions with respect to such U.S. person, and a QEF election may be made by such U.S. person with respect to its indirect interest in us, subject to the discussion in the preceding paragraphs.

We may invest in stock of non-U.S. corporations that are PFICs. In such a case, provided that we are classified as a PFIC, a U.S. Holder would be treated as owning its pro rata share of the stock of the PFIC owned by us. Such a U.S. Holder would be subject to the rules generally applicable to shareholders of PFICs discussed above with respect to distributions received by us from such a PFIC and dispositions by us of the stock of such a PFIC (even though the U.S. Holder may not have received the proceeds of such distribution or disposition). Assuming we receive the necessary information from the PFIC in which we own stock, certain U.S. Holders may make the QEF election discussed above with respect to the stock of the PFIC owned by us, with the consequences discussed above. However, no assurance can be given that we will be able to provide U.S. Holders with such information. A. U.S. Holder generally would not be able to make the mark-to-market election described above with respect to the stock of any PFIC owned by us.

If we were a PFIC, a holder of ordinary shares that is a U.S. Holder must file United States Internal Revenue Service Form 8621 for each tax year in which the U.S. Holder owns the ordinary shares.

You should consult your own tax advisor regarding our potential status as a PFIC and the tax consequences and filing requirements that would arise if we were treated as a PFIC.

Foreign Asset Reporting

Certain U.S. Holders who are individuals (and certain specified entities) are required to report information relating to an interest in ordinary shares, subject to certain exceptions (including an exception for securities held in certain accounts maintained by financial institutions). U.S. Holders are encouraged to consult their own tax advisers regarding the effect of this reporting requirement on their ownership and disposition of ordinary shares.

3.8% Medicare Tax on “Net Investment Income”

Certain U.S. Holders who are individuals, estates or trusts are required to pay an additional 3.8% tax on, among other things, dividends and capital gains from the sale or other disposition of ordinary shares. U.S. Holders are encouraged to consult their own tax advisers regarding the effect of this additional tax on their ownership and disposition of ordinary shares.

Backup Withholding Tax and Information Reporting Requirements

United States backup withholding tax and information reporting requirements generally apply to certain payments to certain non-corporate holders of stock. Information reporting generally will apply to payments of dividends on, and to proceeds from the sale or redemption of, ordinary shares made within the United States, or by a United States payor or United States middleman, to a holder of ordinary shares, other than an exempt recipient (including a corporation, a payee that is not a United States person that provides an appropriate certification and certain other persons). A payor will be required to withhold backup withholding tax from any payments of dividends on, or the proceeds from the sale or redemption of, ordinary shares within the United States, or by a United States payor or United States middleman, to a holder, other than an exempt recipient, if such holder fails to furnish its correct taxpayer identification number or otherwise fails to comply with, or establish an exemption from, such backup withholding tax requirements.

Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against the beneficial owner’s United States federal income tax liability, if any, provided that the required information is furnished to the IRS.

The above description is not intended to constitute a complete analysis of all tax consequences relating to ownership and disposition of our ordinary shares. You should consult your tax advisor concerning the tax consequences of your particular situation.

I. Subsidiary Information

Not applicable.

ITEM 11: Quantitative and Qualitative Disclosures About Market Risk

We are exposed to a variety of market risks, including foreign currency exchange fluctuations, changes in interest rates and inflation. We regularly assess currency, interest rate and inflation risks to minimize any adverse effects on our business as a result of those factors.

Risk of Interest Rate Fluctuation

The primary objectives of our investment activities are to preserve principal, support liquidity requirements, and maximize income without significantly increasing risk. Our investments are subject to market risk due to changes in interest rates, which may affect our interest income and fair market value of our investments.

To minimize this risk, we maintain our portfolio of cash, cash equivalents and short and long-term investments in a variety of securities, including U.S. government and agency securities, and corporate debt securities. We do not have any long-term borrowings. We have a significant amount of cash that is currently invested primarily in interest bearing investment such as bank time deposits, money market funds and available for sale marketable securities. These investments expose us to risks related to changes in interest rates. If interest rates further decline, our results of operations may be adversely affected due to lower interest income from these investments. We do not believe that a 10% increase or decrease in interest rates would have a material impact on our operating results, cash flows or the fair value of our portfolio. The primary objective of our investment activities is to preserve principal while maximizing the income that we receive from our investments without significantly increasing risk and loss. Our investments are exposed to market risk due to fluctuation in interest rates, which may affect our interest income and the fair market value of our investments. We manage this exposure by performing ongoing evaluations of our investments. Due to the short- and medium-term maturities nature of our investments to date, their carrying value approximates the fair value. We generally hold investments to maturity in order to limit our exposure to interest rate fluctuations.

Foreign Currency Exchange Risk

Our foreign currency exposures give rise to market risk associated with exchange rate movements of the U.S. dollar, our functional and reporting currency, mainly against the ILS. In 2017, we derived our revenues primarily in U.S. dollars and a substantial portion in Euros and other currencies. Although a substantial part of our expenses were denominated in U.S. dollars, a significant portion of our expenses were denominated in ILS and to a lesser extent in Euros and other currencies. Our ILS-denominated expenses consist principally of salaries and related personnel expenses. We monitor foreign currency exposure and, from time to time, may use various instruments to preserve the value of sales transactions and commitments; however, this cannot assure our protection against risks of currency fluctuations. Any strengthening or weakening in the value of the ILS against the U.S. is being partially mitigated using hedging transactions and therefore, though we cannot provide any assurance that such transaction will fully mitigate the effect on our net income, it is not likely that such effect will be material.

In the event of a 10% hypothetical strengthening or weakening in the value of the Euro against the U.S. dollar, we may be able to mitigate the effect of such currency exchange fluctuation by adapting our pricing. However, in the event that market conditions will limit our ability to adjust our pricing, we might not be able to fully mitigate the adverse effect of such currency fluctuation. We estimate that in such event, the impact on our net income in 2017 is not likely to exceed $1,000,000. For more information regarding foreign currency related risks, see “ITEM 3: Key Information—Risk Factors—our international operations expose us to the risk of fluctuations in currency exchange rates.”

We use currency forward contracts together with currency options primarily to hedge payments in ILS. These transactions constitute a future cash flow hedge. As of December 31, 2017, we had outstanding forward contracts in the amount of $15.0 million. These transactions were for a period of up to twelve months. As of December 31, 2017, the fair value of the above mentioned foreign currency derivative contracts was $0.2 million.

(b)

Management’s Annual Report on Internal Control over Financial Reporting. Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is a process to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that:

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2017.

In making this assessment, our management used the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our management has concluded, based on its assessment, that our internal control over financial reporting was effective as of December 31, 2017 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external reporting purposes in accordance with generally accepted accounting principles.

Our independent auditors, Kost Forer Gabbay & Kasierer, a member of Ernst & Young Global, have issued an audit report on the effectiveness of our internal control over financial reporting. The report is included with our consolidated financial statements included elsewhere in this annual report.

(c)

Changes in Internal Control over Financial Reporting. During the period covered by this report, no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) have occurred that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 16E: Purchase of Equity Securities by the Company and Affiliated Purchasers

On August 2015, the Board of Directors approved a program for the Company to repurchase up to $15 million of its outstanding ordinary shares, which program was thereafter approved by the Israeli court, pursuant to Israeli law on November 26, 2015. Share purchases will take place in open market transactions or in privately negotiated transactions and may be made from time to time depending on market conditions, share price, trading volume and other factors. Such purchases will be made in accordance with all applicable securities laws and regulations. The repurchase program does not require Allot to acquire a specific number of shares, and may be suspended from time to time or discontinued. The court approvals previously granted were each valid for a period of six months. During 2016, we repurchased a total of 0.8 million shares of our ordinary shares for approximately $3.8 million at an average price of $4.82 per share under this program. During 2017 we did not repurchase any additional outstanding ordinary shares.

ITEM 16F: Change in Registrant’s Certifying Accountant

None.

ITEM 16G: Corporate Governance

As a foreign private issuer, we are permitted under NASDAQ Rule 5615(a)(3) to follow Israeli corporate governance practices instead of the NASDAQ Stock Market requirements, provided we disclose which requirements we are not following and describe the equivalent Israeli requirement. We must also provide NASDAQ with a letter from outside counsel in our home country, Israel, certifying that our corporate governance practices are not prohibited by Israeli law.

We rely on this “foreign private issuer exemption” with respect to the following items:

We follow the requirements of Israeli law with respect to the quorum requirement for meetings of our shareholders, which are different from the requirements of Rule 5620(c). Under our articles of association, the quorum required for an ordinary meeting of shareholders consists of at least two shareholders present in person, by proxy or by written ballot 33.33%, who hold or represent between them at least 25% of the voting power of our shares, instead of the issued share capital provided by under the NASDAQ requirements. This quorum requirement is based on the default requirement set forth in the Companies Law.

We do not seek shareholder approval for equity compensation plans in accordance with the requirements of the Companies Law, which does not fully reflect the requirements of Rule 5635(c). Under Israeli law, we may amend our 2016 Plan by the approval of our board of directors, and without shareholder approval as is generally required under Rule 5635(c). Under Israeli law, the adoption and amendment of equity compensation plans, including changes to the reserved shares, do not require shareholder approval.

We are subject to additional Israeli corporate governance requirements applicable to companies incorporated in Israel whose securities are listed for trading on a stock exchange outside of Israel.

We may in the future provide NASDAQ with an additional letter or letters notifying NASDAQ that we are following our home country practices, consistent with the Companies Law and practices, in lieu of other requirements of Rule 5600.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

ALLOT COMMUNICATIONS LTD.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Allot Communication Ltd. (the “Company“) as of December 31, 2017 and 2016, the related consolidated statements of operations, stockholders‘ equity, and cash flows, for each of the three years in the period ended December 31, 2017, and the related notes and schedules (collectively referred to as the “financial statements“). In our opinion, the financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2017 and 2016, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with US generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 22, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company‘s management. Our responsibility is to express an opinion on the Company‘s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB“) and are required to be independent with respect to the Company in accordance with the US federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTE 2:-

SIGNIFICANT ACCOUNTING POLICIES

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP").

a. Use of estimates:

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions. The Company's management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

b. Financial statements in U.S. dollars:

The majority of the revenues of the Company and its subsidiaries are generated in U.S. dollars ("dollar") or linked to the dollar. In addition, a major portion of the Company's and certain of its subsidiaries' costs are incurred or determined in dollars. The Company's management believes that the dollar is the currency of the primary economic environment in which the Company and its subsidiaries operate. Thus, the functional and reporting currency of the Company and its subsidiaries is the dollar.

Accordingly, monetary accounts maintained in currencies other than the dollar are remeasured into U.S. dollars in accordance with Accounting Standards Codification No. 830, "Foreign Currency Matters" ("ASC No. 830"). All transactions gains and losses from the remeasurement of monetary balance sheet items are reflected in the statements of operations as financial income or expenses as appropriate.

c. Principles of consolidation:

The consolidated financial statements include the accounts of the Company and its subsidiaries. Intercompany balances and transactions have been eliminated upon consolidation.

d. Cash and cash equivalents:

The Company considers all unrestricted highly liquid investments which are readily convertible into cash, with maturity of three months or less at the date of acquisition, to be cash equivalents.

e. Restricted deposits:

The restricted deposits are held in favor of financial institutions in respect of fulfillments of forward contract and operating obligations.

If such assets are considered to be impaired, the impairment charge is recognized in earnings when a decline in the fair value of its investments below the cost basis is judged to be Other-Than-Temporary Impairment (OTTI). Factors considered in making such a determination include the duration and severity of the impairment, the reason for the decline in value, the potential recovery period and the Company's intent to sell, including whether it is more likely than not that the Company will be required to sell the investment before recovery of cost basis. Based on the above factors, the Company concluded that unrealized losses on its available-for-sale securities, for the years ended 2017, 2016 and 2015, were not OTTI.

h. Inventories:

Inventories are stated at the lower of cost or net realizable value. Inventory write-offs are provided to cover risks arising primarily from end of life products and from slow-moving items, technological obsolescence, and excess inventory. Inventory write-offs during the years ended December 31, 2017, 2016 and 2015 amounted to $ 1,260, $ 1,004 and $ 775, respectively, and were recorded in cost of revenues.

Inventory write-off provision as of December 31, 2017 and 2016 amounted to $ 2,756 and $ 1,957, respectively.

Cost is determined using the weighted average cost method.

i. Property and equipment, net:

Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated by the straight-line method over the estimated useful lives of the assets at the following annual rates:

		%

Lab equipment		16 - 25
Computers and peripheral equipment		33
Office furniture		6
Leasehold improvements		Over the shorter of the term of the lease or the useful life of the asset

Goodwill impairment:

Goodwill represents the excess of the purchase price over the fair value of net assets of purchased businesses. Under Accounting Standards Codification No. 350, "Intangibles-Goodwill and Other" ("ASC No. 350"), goodwill is not amortized, but rather subject to an annual impairment test, or more often if there are indicators of impairment present. In accordance with ASC No. 350 the Company performs an annual impairment test at December 31 each year.

ASC 350 allows an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. If the qualitative assessment does not result in a more likely than not indication of impairment, no further impairment testing is required. If it does result in a more likely than not indication of impairment, the two-step impairment test is performed. Alternatively, ASC 350 permits an entity to bypass the qualitative assessment for any reporting unit and proceed directly to performing the first step of the goodwill impairment test.

The first step, identifying a potential impairment, compares the fair value of the reporting unit with its carrying amount. If the carrying amount exceeds its fair value, the second step would need to be performed; otherwise, no further step is required. The second step, measuring the impairment loss, compares the implied fair value of the goodwill with the carrying amount of the goodwill. Any excess of the goodwill carrying amount over the applied fair value is recognized as an impairment loss, and the carrying value of goodwill is written down to fair value.

The Company operates in one operating segment, and this segment comprises its only reporting unit. The Company has performed an annual impairment analysis as of December 31, 2017 and determined that the carrying value of the reporting unit was less than the fair value of the reporting unit. Fair value is determined using market capitalization. During years 2017, 2016 and 2015, no impairment losses were recorded.

Impairment of long lived assets and intangible assets subject to amortization:

Property and equipment and intangible assets subject to amortization are reviewed for impairment in accordance with ASC No. 360, "Accounting for the Impairment or Disposal of Long-Lived Assets," whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets.

Intangible assets acquired in a business combination are recorded at fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and any accumulated impairment losses. The useful lives of intangible assets are assessed to be either finite or indefinite. Intangible assets that are not considered to have an indefinite useful life are amortized over their estimated useful lives. Some of the acquired intangible assets are amortized over their estimated useful lives in proportion to the economic benefits realized. This accounting policy results in accelerated amortization of such customer relationships as compared to the straight-line method. All other intangible assets are amortized over their estimated useful lives on a straight-line basis.

During the years ended December 31, 2017 and 2016, no impairment losses were recorded. During 2015, the Company recorded $ 5,777 impairment loss (see Note 9).

Revenue recognition:

The Company generates revenues mainly from selling its products along with related maintenance and support services. At times, these arrangements may also include professional services, such as installation services or training. The Company generally sells its products through resellers, distributors, OEMs and system integrators, all of whom are considered end-users.

Revenues from product sales are recognized when persuasive evidence of an agreement exists, title and risk of loss have transferred, no significant performance obligations remain, product payment is not contingent upon performance of installation or service obligations, the fee is fixed or determinable and collectability is probable. In instances where acceptance of the product or service is specified by the customer, revenue recognition is deferred until all acceptance criteria have been met.

Maintenance and support related revenues included in multiple element arrangements are deferred and recognized on a straight-line basis over the term of the applicable maintenance and support agreement. Other services are recognized upon the completion of installation or when the service is provided. In instances where the services provided in a multiple element arrangement are considered essential to the functionality of the product and payment of the product is contingent upon performance of the services, the sales of the products and services would be considered one unit of accounting.

Pursuant to the guidance of ASU 2009-13, "Multiple-Deliverable Revenue Arrangements, (amendments to ASC Topic 605, Revenue Recognition)" (ASU 2009-13) and ASU 2009-14, when a sales arrangement contains multiple elements, such as products and services, the Company allocates revenues to each element based on a selling price hierarchy. The selling price for a deliverable is based on VSOE if available, third party evidence ("TPE") if VSOE is not available, or best estimate of selling price ("BESP") if neither VSOE nor TPE is available. In multiple element arrangements, revenues are allocated to each separate unit of accounting for each of the deliverables using the relative selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy.

Revenue arrangements with multiple deliverables are allocated using the relative selling price method. The Company determines the estimated selling price in multiple elements arrangements as follows:

The Company determines the BESP in multiple-element arrangements for the products, based on reviewing historical transactions, and considering several other external and internal factors including, but not limited to, pricing practices including discounting and competition.

The Company determines the selling price for maintenance and support based on VSOE of the price charged based on standalone sales (renewals) of such elements using a consistent percentage of the Company's product price lists.

Deferred revenue includes amounts received from customers for which revenue has not yet been recognized. Deferred revenues are classified as short and long-term based on their contractual term and recognized as revenues at the time the respective elements are provided.

The Company records a provision for estimated product returns based on its experience with historical product returns and other known factors. Such provisions amounted to $ 686 and $ 910 as of December 31, 2017 and 2016, respectively.

m. Advertising expenses:

Advertising expenses are charged to the statement of comprehensive loss, as incurred. Advertising expenses for the years ended December 31, 2017, 2016 and 2015 amounted to $ 1,236, $ 1,081 and $ 1,201, respectively.

n. Research and development costs:

Accounting Standards Codification No. 985-20, requires capitalization of certain software development costs subsequent to the establishment of technological feasibility.

Based on the Company's product development process, technological feasibility is established upon the completion of a working model. The Company does not incur material costs between the completion of a working model and the point at which the products are ready for general release. Therefore, research and development costs are charged to the consolidated statement of comprehensive loss as incurred.

o. Severance pay:

The liability in Israel for substantially all of the Company`s employees in respect of severance pay liability is calculated in accordance with Section 14 of the Severance Pay Law -1963 (herein- "Section 14"). Section 14 states that Company's contributions for severance pay shall be in line of severance compensation and upon release of the policy to the employee, no additional obligations shall be conducted between the parties regarding the matter of severance pay and no additional payments shall be made by the Company to the employee.

Furthermore, the related obligation and amounts deposited on behalf of such obligation under Section 14, are not stated on the balance sheet, because pursuant to current ruling, they are legally released from obligation to employees once the deposits have been paid.

There are a limited number of employees in Israel, for whom the Company is liable for severance pay. The Company's liability for severance pay for its Israeli employees was calculated pursuant to Section 14, based on the most recent monthly salary of its Israeli employees multiplied by the number of years of employment as of the balance sheet date for such employees.

The Company's liability was partly provided by monthly deposits with severance pay funds and insurance policies and the remainder by an accrual.

Severance expense for the years ended December 31, 2017, 2016 and 2015, amounted to $ 1,801, $ 1,976 and $ 2,286, respectively.

p. Accounting for stock-based compensation:

The Company accounts for stock based compensation in accordance with Accounting Standards Codification No. 718, "Compensation - Stock Compensation" ("ASC No. 718") that requires companies to estimate the fair value of equity-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service periods in the Company's consolidated statement of comprehensive loss. The Company recognizes compensation expenses for the value of its awards based on the straight line method over the requisite service period of each of the awards, net of estimated forfeitures.

SIGNIFICANT ACCOUNTING POLICIES (Cont.)

The Company accounted for changes in award terms as a modification in accordance with ASC 718. A modification to the terms of an award should be treated as an exchange of the original award for a new award with total compensation cost equal to the grant-date fair value of the original award plus the incremental value measured at the same date. Under ASC 718, the calculation of the incremental value is based on the excess of the fair value of the new (modified) award based on current circumstances over the fair value of the original award measured immediately before its terms are modified based on current circumstances.

The Company estimated the forfeiture rate based on historical forfeitures of equity awards and adjusted the rate to reflect changes in facts and circumstances, if any. The Company adopted ASU 2016-09 in the first quarter of fiscal year 2017, and elected to retain its existing accounting policy and estimate expected forfeitures. The adoption of this ASU did not have a material impact on the Company's.

The following table sets forth the total stock-based compensation expense resulting from stock options and restricted share units ("RSUs") granted to employees included in the consolidated statements of comprehensive loss, for the years ended December 31, 2017, 2016 and 2015:

	Year ended December 31,
	2017		2016		2015

Cost of revenues	$	362	$	367	$	324
Research and development		648		1,240		1,637
Sales and marketing		1,166		1,833		2,802
General and administrative		1,190		1,701		2,407

Total stock-based compensation expense	$	3,366	$	5,141	$	7,170

The Company selected the binomial option pricing model as the most appropriate fair value method for its stock-based compensation awards with the following assumptions for the years ended December 31, 2017, 2016 and 2015:

	Year ended December 31,
	2017			2016			2015

Suboptimal exercise multiple		2.9-3.5			2.9-3.5			3
Risk free interest rate		0.80%-2.20	%		0.47%-1.58	%		0.23%-2.35	%
Volatility		27%-49	%		33%-51	%		37%-55	%
Dividend yield		0	%		0	%		0	%

The expected annual post-vesting and pre-vesting forfeiture rates affects the number of exercisable options. Based on the Company's historical experience, the annual pre-vesting and post-vesting are in the range of 0%-34% and 0%-29%, respectively, in the years 2017, 2016, and 2015.

The computations of expected volatility and suboptimal exercise multiple is based on the average of the Company's realized historical stock price. The computation of the suboptimal exercise multiple and the forfeiture rates are based on the grantees expected exercise prior and post vesting termination behavior. The interest rate for period within the contractual life of the award is based on the U.S. Treasury Bills yield curve in effect at the time of grant.

The Company currently has no plans to distribute dividends and intends to retain future earnings to finance the development of its business.

The expected life of the stock options represents the weighted-average period the stock options are expected to remain outstanding and is a derived output of the binomial model. The expected life of the stock options is impacted by all of the underlying assumptions used in the Company's model.

q. Treasury stock:

The Company repurchases its Ordinary shares from time to time on the open market and holds such shares as treasury stock. The Company presents the cost to repurchase treasury stock as a reduction of shareholders' equity.

r. Concentration of credit risks:

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, short-term bank deposits, trade receivables and derivative instruments.

The majority of cash and cash equivalents and short-term deposits of the Company are invested in dollar deposits in major U.S. and Israeli banks. Such investments in the United States may be in excess of insured limits and are not insured in other jurisdictions. Generally, the cash and cash equivalents and short-term bank deposits may be redeemed upon demand, and therefore, bear minimal risk.

Marketable securities include investments in dollar linked corporate and municipal bonds. Marketable securities consist of highly liquid debt instruments with high credit standing. The Company’s investment policy, approved by the Board of Directors, limits the amount the Group may invest in any one type of investment or issuer, thereby reducing credit risk concentrations. Management believes that the portfolio is well diversified and, accordingly, minimal credit risk exists with respect to these marketable debt securities

The Company's trade receivables are primarily derived from sales to customers located mainly in EMEA, as well as in APAC, Latin America and the United States. Concentration of credit risk with respect to trade receivables is limited by credit limits, ongoing credit evaluation and account monitoring procedures. The Company performs ongoing credit evaluations of its customers and establishes an allowance for doubtful accounts on a specific basis. Allowance for doubtful accounts amounted to $ 1,292 and $ 924 as of December 31, 2017 and 2016, respectively.

The Company utilizes foreign currency forward contracts to protect against the risk of overall changes in exchange rates. The derivative instruments hedge a portion of the Company's non-dollar currency exposure. Counterparties to the Company’s derivative instruments are all major financial institutions and its exposure is limited to the amount of any asset resulting from the forward contracts.

The Company has no significant off balance sheet concentrations of credit risk.

s. Grants from the Israel Innovation Authority:

Participation grants from the Israel Innovation Authority (Previously known as the Office of the Chief Scientist) for research and development activity are recognized at the time the Company is entitled to such grants on the basis of the costs incurred and included as a deduction of research and development costs. Research and development non royalty bearing grants recognized amounted to $ 392, $ 606 and $ 1,252 in 2017, 2016 and 2015, respectively.

t. Income taxes:

The Company accounts for income taxes in accordance with Accounting Standards Codification No. 740, "Income Taxes" ("ASC No. 740"). ASC No. 740 prescribes the use of the liability method, whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance, if necessary, to reduce deferred tax assets to their estimated realizable value if it is more likely than not that some portion or all of the deferred tax assets will not be realized. The deferred tax assets and liabilities are classified to non-current assets and liabilities, respectively.

u. Basic and diluted net income (loss) per share:

Basic net income (loss) per share is computed based on the weighted average number of Ordinary Shares outstanding during each year. Diluted net income (loss) per share is computed based on the weighted average number of Ordinary Shares outstanding during each year, plus dilutive potential Ordinary Shares considered outstanding during the year, in accordance with FASB ASC 260 "Earnings Per Share".

For the years ended December 31, 2017, 2016 and 2015, all outstanding options and RSUs have been excluded from the calculation of the diluted net loss per share since their effect was anti-dilutive. See Note 16.

v. Comprehensive loss:

The Company accounts for comprehensive loss in accordance with Accounting Standards Codification No. 220, "Comprehensive Income" ("ASC No. 220"). This statement establishes standards for the reporting and display of comprehensive loss and its components in a full set of general purpose financial statements. Comprehensive loss represents all changes in shareholders' equity during the period except those resulting from investments by, or distributions to shareholders. The Company determined that its items of comprehensive loss relate to unrealized gains and losses on hedging derivative instruments and unrealized gains and losses on available-for-sale marketable securities.

The following table shows the components and the effects on net loss of amounts reclassified from accumulated other comprehensive loss as of December 31, 2017:

	Year ended December 31, 2017
	Unrealized losses on marketable securities			Unrealized gains (losses) on cash flow hedges			Total

w. Fair value of financial instruments:

The Company measures its cash and cash equivalents, marketable securities, derivative instruments, short-term bank deposits, trade receivables, other receivables, trade payables and other payables at fair value. The carrying amounts of short-term bank deposits, trade receivables, other receivables, trade payables and other payables approximate their fair value due to the short-term maturities of such instruments.

Fair value is an exit price, representing the amount that would be received if the Company were to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability.

NOTE 2:-

SIGNIFICANT ACCOUNTING POLICIES (Cont.)

The Company uses a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

Level 1 -

Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 -

Include other inputs that are directly or indirectly observable in the marketplace, other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets with insufficient volume or infrequent transactions, or other inputs that are observable (model-derived valuations in which significant inputs are observable), or can be derived principally from or corroborated by observable market data; and

Level 3 -

Unobservable inputs which are supported by little or no market activity.

The Company categorized each of its fair value measurements in one of those three levels of hierarchy. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The Company's earn-out consideration is classified within Level 3. The valuation methodology used by the Company to calculate the fair value consideration is the discounted cash flow using Monte-Carlo simulation method by taking into account, forecast future revenues, expected volatility of 41.1% and weighted average cost of debt of 2%.

x. Derivatives and hedging:

The Company accounts for derivatives and hedging based on Accounting Standards Codification No. 815, "Derivatives and Hedging" ("ASC No. 815").

The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value. Derivative instruments that are not designated and qualified as hedging instruments must be adjusted to fair value through earnings.

For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income (loss) in shareholders' equity and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument is recognized in current earnings. To apply hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions.

Business combinations:

The Company accounts for business combinations in accordance with ASC No. 805. ASC No. 805 requires recognition of assets acquired, liabilities assumed, and any non-controlling interest at the acquisition date, measured at their fair values as of that date. Any excess of the fair value of net assets acquired over the purchase price is recorded as goodwill and any subsequent changes in estimated contingencies are to be recorded in earnings. In addition, changes in valuation allowance related to acquired deferred tax assets and acquired income tax positions are to be recognized in earnings.

z. Warranty costs:

The Company generally provides three months software and a one year hardware warranty for all of its products. A provision is recorded for estimated warranty costs at the time revenues are recognized based on the Company's experience. Warranty expenses for the years ended December 31, 2017, 2016 and 2015 were immaterial.

aa. Recently Issued Accounting Pronouncements:

In January 2016, the FASB issued a new standard to amend certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Most prominent among the amendments is the requirement for changes in the fair value of our equity investments, with certain exceptions, to be recognized through net income rather than accumulated other comprehensive income (loss). ASU 2016-01 is effective for annual reporting periods, and interim periods within those years beginning after December 15, 2017. This new guidance doesn’t have a material impact on the Company’s Consolidated Financial Statements.

In February 2016, the FASB issued ASU 2016-02, “Leases”, on the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for in a manner similar to the accounting under existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASC 842 supersedes the previous leases standard, ASC 840, "Leases". The guidance is effective for the interim and annual periods beginning on or after December 15, 2018, and early adoption is permitted. The Company is currently in the process of evaluating the impact of the adoption of ASU 2016-02 on its consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). The standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. ASU 2016-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company is currently evaluating the impact of this standard on its Consolidated Financial Statements.

In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18), which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. This new guidance doesn't have a material impact on the Company’s Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" ("ASU 2017-04"). ASU 2017-04 eliminates the requirement to measure the implied fair value of goodwill by assigning the fair value of a reporting unit to all assets and liabilities within that unit (the "Step 2 test") from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited by the amount of goodwill in that reporting unit. ASU 2017-04 will become effective for the Company beginning January 1, 2020 and must be applied to any annual or interim goodwill impairment assessments after that date. Early adoption is permitted. The Company is currently evaluating the effect that the adoption of ASU 2017-04 will have on its consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Stock Compensation – Scope of Modification Accounting, guidance that clarifies that all changes to share-based payment awards are not necessarily accounted for as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award changes as a result of the change in terms or conditions. This guidance is effective prospectively beginning January 1, 2018. This guidance will apply to any future modifications. The Company does not expect this guidance to have a material impact on our consolidated financial statements.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The objectives of this ASU are to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements and to make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. This ASU is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The Company is currently evaluating the effect of the adoption of this ASU.

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-09, “Revenue from Contracts with Customers”, an updated standard on revenue recognition and issued subsequent amendments to the initial guidance in March 2016, April 2016, May 2016 and December 2016 within ASU 2016-08, 2016-10, 2016-12 and 2016-20, respectively. The new standards provide enhancements to the quality and consistency of how revenue is reported while also improving comparability in the financial statements of companies reporting using IFRS and US GAAP. The core principle of the new standard is for companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration (that is, payment) to which the company expects to be entitled in exchange for those goods or services. The new standard also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively (for example, service revenue and contract modifications) and improve guidance for multiple-element arrangements. ASU 2014-09 was initially scheduled to be effective for annual and interim reporting periods beginning after December 15, 2016 and may be adopted either on a full retrospective or modified retrospective approach. However, on July 9, 2015, the FASB approved a one year deferral of the effective date of ASU 2014-09. The revised effective date is for annual reporting periods beginning after December 15, 2017 and interim periods thereafter, with an early adoption permitted as of the original effective date. The Company has decided to adopt this standard effective January 1, 2018 using the modified retrospective approach with cumulative effect of applying the new guidance recognized as an adjustment to the opening retained earnings balance, which is $712. In preparation for adoption of the standard, the Company has implemented internal controls and key system functionality to enable the preparation of financial information and have reached conclusions on key accounting assessments related to the standard, including the assessment of the impact.

Adoption of the standard will result in a reduction of deferred revenues of $712 as of January 1, 2018 to be recorded in accumulated deficit due to upfront recognition of license revenues from term licenses.

FAIR VALUE MEASUREMENTS

In accordance with ASC No. 820, the Company measures its marketable securities and foreign currency derivative instruments at fair value. Cash equivalents and available for sale marketable securities are classified within Level 1 or Level 2. This is because these assets are valued using quoted market prices or alternative pricing sources and models utilizing market observable inputs.

The earn-out liability related to the acquisition of Optenet is classified within Level 3 because this liability is based on present value calculations and an external valuation model whose inputs include market interest rates, estimated operational capitalization rates and volatilities.

The Company's financial net assets measured at fair value on a recurring basis, including accrued interest components, consisted of the following types of instruments as of December 31, 2017 and 2016, respectively:

DERIVATIVE INSTRUMENTS

The Company enters into hedge transactions with a major financial institution, using derivative instruments, primarily forward contracts and options to purchase and sell foreign currencies, in order to reduce the net currency exposure associated with anticipated expenses (primarily salaries and related expenses that are designated as cash flow hedges) in currencies other than U.S. dollar, and forecasted revenues denominated in Euro. The net income (loss) recognized in "Financial income (expense), net" during the years ended December 31, 2017, 2016 and 2015 was $ (1,801), $ 286 and $ 1,200, respectively.

The Company currently hedges such future exposures for a maximum period of one year. However, the Company may choose not to hedge certain foreign currency exchange exposures for a variety of reasons, including but not limited to immateriality, accounting considerations and the prohibitive economic cost of hedging particular exposures. There can be no assurance the hedges will offset more than a portion of the financial impact resulting from movements in foreign currency exchange rates.

The Company records all derivatives on the consolidated balance sheets at fair value in accordance with ASC No. 820 at Level 2. The effective portion of cash flow hedges are recorded in other comprehensive income (loss) until the hedged item is recognized in earnings. The ineffective portion of cash flow hedges are adjusted to fair value through earnings in financial income (expenses), net. The Company does not enter into derivative transactions for trading purposes.

The Company had a net unrealized income (loss) associated with cash flow hedges of $ 159 and $ (61) recorded in other comprehensive loss as of December 31, 2017 and 2016, respectively. As of December 31, 2017 and 2016, the Company had outstanding hedge transactions in the amount of $ 14,994 and $ 13,302, respectively.

The fair value of the outstanding foreign exchange contracts recorded by the Company on its consolidated balance sheets as of December 31, 2017 and 2016, as assets and liabilities is as follows:

Foreign exchange forward and		December 31,
options contracts	Balance sheet	2017			2016

Fair value of foreign exchange hedge transactions	Other receivables and prepaid expenses	$	160		$	40
Fair value of foreign exchange hedge transactions	Other payables and accrued expenses		(1	)		(101	)

Total derivatives designated as hedging instruments	Other Comprehensive income (loss)	$	159		$	(61	)

Gain or loss on the derivative instruments, which partially offset the foreign currency impact from the underlying exposures, reclassified from other comprehensive loss to operating expenses for the years ended December 31, 2017, 2016 and 2015 were $ (796) $ (242) and $ 1,407, respectively.

DERIVATIVE INSTRUMENTS (Cont.)

Non-designated hedges:

The Company also uses foreign currency forward contracts to mitigate variability in gains and losses generated from the re-measurement of certain monetary assets and liabilities denominated in foreign currencies. These derivatives do not qualify for special hedge accounting treatment. These derivatives are carried at fair value with changes recorded in financial income, net. Changes in the fair value of these derivatives are largely offset by re-measurement of the underlying assets and liabilities. Cash flows from such derivatives are classified as operating activities. The derivatives have maturities of approximately twelve months. As of December 31, 2017 and 2016, the Company’s transactions were $ 24,593 and $ 14,969, respectively.

The fair value of the outstanding non-designated foreign exchange contracts recorded by the Company on its consolidated balance sheets as of December 31, 2017 and 2016, as assets and liabilities is as follows:

b. Major subcontractor:

The Company currently depends on one subcontractor to manufacture and provide hardware, warranty and support for its traffic management systems. If the subcontractor experiences delays, disruptions, quality control problems or a loss in capacity, shipments of products may be delayed and the Company's ability to deliver products could be materially adversely affected. Certain hardware components for the Company's products come from single or limited sources, and the Company could lose sales if these sources fail to satisfy its supply requirements. In the event that the Company terminates its business connection with the subcontractor, it will have to compensate the subcontractor for certain inventory costs, as specified in the agreement with the subcontractor.

c. Litigations:

On February 18, 2016, a former employee filed a claim against the Company alleging that he is entitled to compensation for unlawful dismissal by the Company.

TAXES ON INCOME (Cont.)

Tax benefits under Israel's law for the Encouragement of Capital Investments, 1959 ("the Law"):

In 1998, the production facilities of the Company related to its computational technologies were granted the status of an "Approved Enterprise" under the Law. In 2004, an expansion program was granted the status of "Approved Enterprise". According to the provisions of the Law, the Company has elected the alternative track of benefits and has waived Government grants in return for tax benefits. The period of tax benefits, detailed above, is limited to the earlier of 12 years from the commencement of production, or 14 years from the approval date.

According to the provisions of the Law under the alternative track, the Company's income may be tax-exempt for a period of two years commencing with the year it first earns taxable income, and subject to corporate taxes at the reduced rate of 10% to 25%, for an additional period of five to eight years depending upon the level of foreign ownership of the Company.

The Law was significantly amended effective April 1, 2005 ("the 2005 - Amendment"). The 2005 - Amendment includes revisions to the criteria for investments qualified to receive tax benefits as a Beneficiary Enterprise and among other things, simplifies the approval process. The Amendment applies to new investment programs. Therefore, investment programs commencing after December 31, 2004, do not affect the approved programs of the Company.

In addition, the Law provides that terms and benefits included in any letter of approval already granted will remain subject to the provisions of the Law as they were on the date of such approval. Therefore, the Company's existing Approved Enterprise will generally not be subject to the provisions of the 2005 - Amendment. The Company elected 2006 and 2009 as "year of election" under the 2005 - Amendment.

The entitlement to the above benefits is contingent upon the fulfillment of the conditions stipulated in the Law, regulations published thereunder and the criteria set forth in the specific letters of approval. In the event of failure to comply with these conditions, the benefits may be canceled and the Company may be required to refund the amount of the benefits, in whole or in part, including interest and linked to changes in the Israeli CPI. As of December 31, 2017, management believes that the Company meets the aforementioned conditions.

If the Company pays a dividend out of exempt income derived from the Approved and Beneficiary Enterprise, it will be subject to corporate tax in respect of the gross amount distributed, including any taxes thereon, at the rate which would have been applicable had it not enjoyed the alternative benefits, generally 10%-25%, depending on the percentage of the Company's Ordinary shares held by foreign shareholders. The dividend recipient is subject to withholding tax at the rate of 15% applicable to dividends from approved enterprises, if the dividend is distributed during the tax exemption period or within twelve years thereafter. The Company currently has no plans to distribute dividends and intends to retain future earnings to finance the development of its business.

NOTE 13:-

TAXES ON INCOME (Cont.)

As of December 31, 2017, there is no income earned by the Company Israel’s “Approved Enterprises” and “Beneficiary Enterprise”.

Income from sources other than the "Approved and Beneficiary Enterprise" during the benefit period will be subject to tax at the regular corporate tax rate.

As of January 1, 2011, new legislation amending the Law came into effect (the "2011 Amendment"). The 2011 Amendment introduced a new status of "Preferred Company" and "Preferred Enterprise", replacing the then existing status of "Beneficiary Company" and "Beneficiary Enterprise". Similarly to "Beneficiary Company", a Preferred Company is an industrial company owning a Preferred Enterprise which meets certain conditions (including a minimum threshold of 25% export). However, under this legislation the requirement for a minimum investment in productive assets was cancelled.

Under the 2011 Amendment, a uniform corporate tax rate will apply to all qualifying income of the Preferred Company, as opposed to the former law, which was limited to income from the Approved Enterprises and Beneficiary Enterprise during the benefits period. The uniform corporate tax rate was 9% in areas in Israel designated as Development Zone A and 16% elsewhere in Israel during 2016 and 2017.

A dividend distributed from income which is attributed to a Preferred Enterprise/Special Preferred Enterprise will be subject to withholding tax at source at the following rates: (i) Israeli resident corporation – 0%, (ii) Israeli resident individual – 20% as of 2014 and thereafter (iii) non-Israeli resident - 20% as of 2014 and thereafter subject to a reduced tax rate under the provisions of an applicable double tax treaty.

In December 2016, the Economic Efficiency Law (Legislative Amendments for Applying the Economic Policy for the 2017 and 2018 Budget Years), 2016 which includes Amendment 73 to the Law for the Encouragement of Capital Investments ("the 2016 - Amendment") was published. According to the 2016 - Amendment, a preferred enterprise located in development area A will be subject to a tax rate of 7.5% instead of 9% effective from January 1, 2017 and thereafter (the tax rate applicable to preferred enterprises located in other areas remains at 16%).

The December 2016 amendment also prescribes special tax tracks for technological enterprises, the new tax tracks under the amendment are as follows:

Technological preferred enterprise - an enterprise whose total consolidated revenues (parent company and all subsidiaries) is less than NIS 10 billion. A technological preferred enterprise, as defined in the Law, which is located in the center of Israel will be subject to tax at a rate of 12% on profits deriving from intellectual property (in development area A - a tax rate of 7.5%).

Special technological preferred enterprise - an enterprise whose total consolidated revenues (parent company and all subsidiaries) exceeds NIS 10 billion. Such enterprise will be subject to tax at a rate of 6% on profits deriving from intellectual property, regardless of the enterprise’s geographical location.

TAXES ON INCOME (Cont.)

Under the transition provisions of the 2016 Amendment, the Company may decide to irrevocably implement the new law while waiving benefits provided under the current law or to remain subject to the current law.

Tax benefits under the law for the Encouragement of Industry (Taxes), 1969 (the "Encouragement Law"):

The Encouragement Law, provides several tax benefits for industrial companies. An industrial company is defined as a company resident in Israel, at least 90% of the income of which in a given tax year exclusive of income from specified Government loans, capital gains, interest and dividends, is derived from an industrial enterprise owned by it. An industrial enterprise is defined as an enterprise whose major activity in a given tax year is industrial production activity.

Management believes that the Company is currently qualified as an "industrial company" under the Encouragement Law and as such, enjoys tax benefits, including: (1) deduction of purchase of know-how and patents and/or right to use a patent over an eight-year period; (2) the right to elect, under specified conditions, to file a consolidated tax return with additional related Israeli industrial companies and an industrial holding company; (3) accelerated depreciation rates on equipment and buildings; and (4) expenses related to a public offering on the Tel-Aviv Stock Exchange and on recognized stock markets outside of Israel, are deductible in equal amounts over three years.

Eligibility for benefits under the Encouragement Law is not subject to receipt of prior approval from any governmental authority. No assurance can be given that the Israeli tax authorities will agree that the Company qualifies, or, if the Company qualifies, then the Company will continue to qualify as an industrial company or that the benefits described above will be available to the Company in the future.

h. Net operating losses carry forward:

The Company has accumulated net operating losses for tax purposes as of December 31, 2017, in the amount of approximately $ 52,966, which may be carried forward and offset against taxable income in the future for an indefinite period. In December 2014, the Israeli Tax Authorities approved a final tax ruling with respect to the Company’s acquisition of Oversi. According to the ruling, the net operating losses may be offset against taxable income annually with a limitation of up to 14% of the total accumulated losses but no more than 50% of the Company's taxable income. As of December 31, 2017, the Company recorded a full valuation allowance with respect to its deferred tax assets in Allot Communications Ltd. and wrote-off prepaid and withholding taxes of $ 2,668 as the Company does not expect to utilize these tax assets in the near future. In addition, the Company has accumulated capital losses for tax purposes as of December 31, 2017, of approximately $ 27,300, which may be carried forward and offset against taxable capital gains in the future for an indefinite period, but are limited as stated above with regard to the Oversi merger. Management currently believes that since the Company has a history of losses, and uncertainty with respect to future taxable income, it is more likely than not that the deferred tax assets regarding the loss carry forwards will not be utilized in the foreseeable future. Thus, a valuation allowance was provided to reduce deferred tax assets to their realizable value.

The U.S. subsidiary has accumulated losses for U.S. federal income tax return purposes of approximately $ 5,910 and $ 5,285 for state taxes. The federal accumulated losses for tax purposes expire between 2026 and 2032. The state accumulated losses for tax purposes began to expire in 2014. As of December 31, 2017, the Company recorded a valuation allowance with respect to its deferred tax assets in the US Subsidiary.

Such losses are subject to limitations of Internal Revenue Code, Section 382, which in general provides that utilization of net operating losses is subject to an annual limitation if an ownership change results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. The annual limitations may result in the expiration of losses before utilization.

In December 2107 the U.S. Tax Cuts and Jobs Act of 2017 was signed into law. This legislation makes significant changes to the U.S. Internal Revenue Code. Such changes include a reduction in the corporate tax rate, changes in U.S. international taxation and limitations on certain corporate deductions and credits, among other changes. The deferred tax asset at December 31, 2017 reflects the impact of the US Tax reform.

The Company conducts business globally and, as a result, the Company or one or more of its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. In the normal course of business, the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as Israel, France, and the United States. With a few exceptions, the Company is no longer subject to Israeli tax assessment through the year 2012 and the European and U.S. subsidiaries have final tax assessments through 2013. The Company is currently under audit by the Israeli Tax Authorities for the years 2013 – 2016.
