NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1 — The Company and Summary of Significant Accounting Policies

The Company

Energy Recovery, Inc. (the “Company”, “Energy Recovery”, “we”, “our”, or “us”) designs, develops, manufactures, and sells energy recovery devices that harness the reusable energy from industrial fluid flows and pressure cycles. Our products are marketed and sold in fluid flow markets under the trademarks ERI^®, PX^®, Pressure Exchanger^®, and PX Pressure Exchanger^®. Our products are developed and manufactured in the United States of America (“U.S.”) at our headquarters in San Leandro, California. We also have sales offices in Madrid, Spain; Dubai, United Arab Emirates; and Shanghai, Peoples Republic of China.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires our management to make judgments, assumptions, and estimates that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Our most significant estimates and judgments involve the determination of revenue recognition; allowance for doubtful accounts; allowance for product warranty; valuation of stock options; valuation and impairment of goodwill, long-lived assets, and acquired intangible assets; valuation of fair value of assets held for sale; useful lives for depreciation and amortization; valuation adjustments for excess and obsolete inventory; deferred taxes and valuation allowances on deferred tax assets; and evaluation and measurement of contingencies, including contingent consideration. Actual results could differ materially from those estimates.

Basis of Presentation

The condensed consolidated financial statements include the accounts of Energy Recovery, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

The accompanying condensed consolidated financial statements have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The December 31, 2012 condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP; however, we believe that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2012 included in our Annual Report on Form 10-K filed with the SEC on March 12, 2013.

In the opinion of management, all adjustments, consisting of only normal recurring adjustments that are necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, have been made. The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any future periods.

Recent Accounting Pronouncements

In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The amendment requires that an unrecognized tax benefit be presented in financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. If an applicable deferred tax asset is not available or a company does not expect to use the applicable deferred tax asset, the unrecognized tax benefit should be presented as a liability in the financial statements and should not be combined with an unrelated deferred tax asset. The amendment is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date; however, retrospective application is permitted. Adoption of this guidance is not expected to have a significant impact on our financial statements.

In April 2013, the FASB issued ASU No. 2013-07, Liquidation Basis Accounting. The amendment requires (1) an entity to prepare its financial statements using the liquidation basis of accounting when liquidation is imminent; (2) that financial statements prepared using the liquidation basis of accounting present relevant information about an entity’s expected resources in liquidation by measuring and presenting assets at the amount of the expected cash proceeds from liquidation; and (3) disclosures about an entity’s plan for liquidation, the methods and significant assumptions used to measure assets and liabilities, the type and amount of costs and income accrued, and the expected duration of the liquidation process. This update is effective prospectively for entities that determine liquidation is imminent during the annual reporting periods beginning after December 15, 2013 and interim reporting periods therein. Adoption of this guidance is not expected to have an impact on our financial statements absent any indication that liquidation is imminent.

In March 2013, the FASB issued ASU No. 2013-05, Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity. The amendment is to resolve the diversity in practice of which subtopic applies to the release of the cumulative translation adjustment into net income when a parent company either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity. This update is effective prospectively for reporting periods after December 15, 2013. Adoption of this guidance is not expected to have a material impact on our financial statements.

In February 2013, the FASB issued ASU No. 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date. The standard provides guidance on the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this update is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. This update is effective for reporting periods after December 15, 2013. Adoption of this guidance is not expected to have a material impact on our financial statements.

Also in February 2013, the FASB issued ASU No. 2013-02, Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income. The standard requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and present significant amounts reclassified by the respective line items of net income, but only if the reclassified amount is required to be reclassified by U.S. GAAP. Amounts not required to be reclassified by U.S. GAAP must be cross-referenced to other disclosures required by U.S. GAAP that provide additional detail about those amounts. This update is effective prospectively for reporting periods after December 15, 2012, with early adoption permitted. Adoption of this guidance required additional disclosure, but did not have a material impact on our financial statements.

In January 2013, the FASB issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. The update was issued to address implementation issues about the scope of ASU 2011-11, Disclosures about Offsetting Assets and Liabilities. The amendment affects entities that have derivatives, including bifurcated embedded derivatives, repurchase agreements, reverse repurchase agreements, securities borrowing, and securities lending transactions that are either offset or subject to an enforceable master netting arrangement or similar agreement. Entities with other types of financial assets and liabilities subject to a master netting arrangement or similar agreement are also affected because this amendment makes them no longer subject to the disclosure requirements of ASU No. 2011-11. This amendment is applicable for periods beginning on or after January 1, 2013. Adoption of this guidance did not have a material impact on our financial statements.

In July 2012, the FASB issued ASU No. 2012-02, Intangibles-Goodwill and Other, Testing Indefinite-Lived Assets for Impairment. The standard provides entities an option to perform a qualitative assessment to determine whether the existence of events and circumstances indicate that it is more likely than not that the indefinite-lived intangible asset is impaired. If an entity concludes, as a result of its qualitative assessment, that it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount, then the quantitative impairment test is required. Otherwise, no further testing is required. This standard is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. Adoption of this guidance did not have a material impact on our financial statements.

Note 2 — Goodwill and Other Intangible Assets

Goodwill of $12.8 million at September 30, 2013 and December 31, 2012 was the result of our acquisition of Pump Engineering, LLC in December 2009. During the three and nine months ended September 30, 2013, there were no changes in the recognized amount of goodwill.

The components of identifiable other intangible assets, all of which are finite-lived, as of September 30, 2013 and December 31, 2012, respectively, were as follows (in thousands):

	September 30, 2013
	Gross Carrying Amount		Accumulated Amortization			Accumulated Impairment Losses			Net Carrying Amount
Developed technology	$	6,100	$	(2,338	)	$	—		$	3,762
Non-compete agreements		1,310		(1,131	)		—			179

Total	$	11,485	$	(6,185	)	$	(1,062	)	$	4,238

	December 31, 2012
	Gross Carrying Amount		Accumulated Amortization			Accumulated Impairment Losses			Net Carrying Amount
Developed technology	$	6,100	$	(1,881	)	$	—		$	4,219
Non-compete agreements		1,310		(1,015	)		—			295
Backlog		1,300		(1,300	)		—			—
Trademarks		1,200		(180	)		(1,020	)		—
Customer relationships		990		(792	)		—			198
Patents		585		(326	)		(42	)		217
Total	$	11,485	$	(5,494	)	$	(1,062	)	$	4,929

In 2012, we determined that the capitalized cost associated with our acquired trademark intangibles was impaired with the launch of the Company’s new branding strategy and the discontinuation of the use of the trademarks “PEI” and “Pump Engineering” in the fourth quarter of 2012. Accordingly, we recorded an impairment charge of $1.0 million for the year ended December 31, 2012 and have not recorded any amortization expense in 2013 related to this intangible asset.

Note 3 — Loss per Share

Basic and diluted loss per share are based on the weighted average number of common shares outstanding during the period. Potentially dilutive securities are excluded from the calculation of loss per share, as their inclusion would be anti-dilutive.

The following table shows the computation of basic and diluted loss per share (in thousands, except per share data):

	Three Months Ended September 30,						Nine Months Ended September 30,
	2013			2012			2013			2012
Numerator:
Net loss	$	(3,866	)	$	(1,826	)	$	(9,833	)	$	(6,070	)

Denominator:

Basic and diluted loss per share	$	(0.08	)	$	(0.04	)	$	(0.19	)	$	(0.12	)

The following potential common shares were not considered for the computation of diluted loss per share because their effect would have been anti-dilutive (in thousands):

	Three and Nine Months Ended September 30,
	2013		2012
Stock options		7,303		6,595
Warrants		900		970
Restricted awards*		—		5

* Includes restricted stock and restricted stock units.

Land and Building Held for Sale

In 2011, we initiated a restructuring plan to consolidate our North American operations and transfer our Michigan-based operations to our manufacturing center and headquarters in San Leandro, California. In connection with this restructuring plan, we classified the land and building located in Michigan as assets held for sale at December 31, 2011. At December 31, 2012 and June 30, 2013, these assets totaled $1.3 million. The assets were sold in September 2013. Net proceeds from the sale totaled $1.2 million, resulting in a loss on sale of $0.1 million. As the assets were part of the restructuring plan, the loss on sale was reported in the Condensed Consolidated Statement of Operations as restructuring charges.

Note 6 — Debt

Lines of Credit

In June 2012, we entered into a loan agreement (the “2012 Agreement”) with a financial institution. The 2012 Agreement provides for a total available credit line of $16.0 million. Under the 2012 Agreement, we are allowed to draw advances not to exceed, at any time, $10.0 million as revolving loans. The total stand-by letters of credit issued under the 2012 Agreement may not exceed the lesser of the $16.0 million credit line or the credit line minus all outstanding revolving loans. At no time may the aggregate of the revolving loans and stand-by letters of credit exceed the total available credit line of $16.0 million. Revolving loans may be in the form of a base rate loan that bears interest equal to the prime rate plus 0% or a Eurodollar loan that bears interest equal to the adjusted LIBO rate plus 1.25%. Stand-by letters of credit are subject to customary fees and expenses for issuance or renewal. The unused portion of the credit facility is subject to a facility fee in an amount equal to 0.25% per annum of the average unused portion of the revolving line. The 2012 Agreement also requires us to maintain a cash collateral balance equal to 101% of all outstanding advances and all outstanding stand-by letters of credit collateralized by the line of credit. The 2012 Agreement matures on June 5, 2015 and is collateralized by substantially all of our assets. At December 31, 2012, the amount of outstanding stand-by letters of credit collateralized under the 2012 Agreement totaled $1.4 million. As of September 30, 2013, there were no advances drawn and $0.7 million in stand-by letters of credit collateralized under the 2012 Agreement. Total restricted cash related to these stand-by letters of credit totaled $0.7 million as of September 30, 2013.

We are subject to certain financial and administrative covenants under the 2012 Agreement. As of September 30, 2013, we were in compliance with these covenants.

In 2009, we entered into a loan and security agreement (the “2009 Agreement”) with another financial institution. The 2009 Agreement, as amended, provided a total available credit line of $16.0 million. Under the 2009 Agreement, we were allowed to draw advances of up $10.0 million on a revolving line of credit or utilize up to $15.9 million as collateral for stand-by letters of credit, provided that the aggregate of the outstanding advances and collateral did not exceed the total available credit line of $16.0 million. Advances under the revolving line of credit incurred interest based on a prime rate index or LIBOR plus 1.375%. The 2009 Agreement, as amended, also required us to maintain cash collateral balances equal to at least 101% of the face amount of all outstanding stand-by letters of credit collateralized by the line of credit and 100% of the amount of all outstanding advances. The amended 2009 Agreement expired on May 30, 2012. There were no advances drawn under the 2009 Agreement’s credit line at the time it expired. At December 31, 2012, the amount of remaining outstanding stand-by letters of credit issued under the 2009 Agreement totaled $4.3 million. As of September 30, 2013, remaining stand-by letters of credit issued under the 2009 Agreement totaled $4.0 million. Total restricted cash related to these stand-by letters of credit was approximately $4.0 million as of September 30, 2013.

Note 7 — Equity

Share-Based Compensation Expense

For the three and nine months ended September 30, 2013 and 2012, we recognized share-based compensation expense related to employees and consultants as follows (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2013		2012		2013		2012
Cost of revenue	$	18	$	25	$	57	$	90
General and administrative		339		440		1,153		1,464
Sales and marketing		123		94		358		434
Research and development		50		30		149		109
Total share-based compensation expense	$	530	$	589	$	1,717	$	2,097

As of September 30, 2013, total unrecognized compensation cost related to non-vested share-based awards, net of estimated forfeitures, was $3.4 million, which is expected to be recognized as expense over a weighted average period of approximately 2.4 years.

In January 2013, we granted 100,000 stock options to an employee in connection with the offer letter of employment in July 2011. The options vest over a four-year period beginning on the first day of employment, have an exercise price of $3.42 per share based on the date of grant, and expire 10 years from the grant date.

In March 2013, we granted 843,600 stock options to certain officers and other employees. The options vest over a four-year period, have an exercise price of $3.92 per share, and expire 10 years from the grant date.

During the third quarter of 2013, we granted 120,652 stock options to the non-employee members of our Board of Directors in accordance with the annual compensation terms approved by the Compensation Committee of the Board of Directors. The options fully vest in June 2014, have an exercise price of $5.43 per share, and expire 10 years from the grant date.

Note 8 — Income Taxes

The effective income tax rate for the nine months ended September 30, 2013 and 2012 was an expense of (2.7%) and a benefit of 4.0%, respectively. The tax expense for the nine months ended September 30, 2013 primarily relates to the accretion of the deferred tax liability for the timing difference regarding the tax basis of goodwill recognized during the period and the truing up of tax refunds receivable following the net operating loss and general business credit carrybacks to prior tax years. The net loss for the nine months ended September 30, 2013 did not yield an income tax benefit as we continue to provide a full valuation allowance on our deferred tax assets. The tax benefit recognized for the nine months ended September 30, 2012 primarily related to the recognition of state tax refunds from prior-year returns.

Note 9 — Commitments and Contingencies

Balance, end of period	$	1,036		$	1,018		$	1,036		$	1,018

Based on management’s analysis of warranty liability experience, we recorded a change in estimate of our warranty reserve of $132,000 during the second quarter of 2013.

Purchase Obligations

We enter into purchase order arrangements with our vendors. As of September 30, 2013, there are open purchase orders for which we have not yet received the related goods or services. These arrangements are subject to change based on our sales demand forecasts, and we have the right to cancel the arrangements prior to the date of delivery. As of September 30, 2013, we had approximately $3.0 million of cancellable open purchase order arrangements related primarily to materials and parts.

Guarantees

We enter into indemnification provisions under our agreements with other companies in the ordinary course of business, typically with customers. Under these provisions, we generally indemnify and hold harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of our activities, generally limited to personal injury and property damage caused by our employees at a customer’s desalination plant in proportion to the employee’s percentage of fault for the accident. Damages incurred for these indemnifications would be covered by our general liability insurance to the extent provided by the policy limitations. We have not incurred material costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the estimated fair value of these agreements is not material. Accordingly, we have no liabilities recorded for these agreements as of September 30, 2013 and December 31, 2012.

In certain cases, we issue warranty and product performance guarantees to our customers for amounts ranging from 10% to 20%, and in some cases up to 30%, of the total sales agreement to endorse the execution of product delivery and the warranty of design work, fabrication, and operating performance. These guarantees, generally in the form of stand-by letters of credit or bank guarantees secured by stand-by letters of credit, typically remain in place for periods ranging from 12 to 36 months and, in some cases up to 65 months, and relate to the underlying product warranty period. The stand-by letters of credit are collateralized by restricted cash and our credit facility. Of the $4.7 million in outstanding stand-by letters of credit at September 30, 2013, $4.0 million was issued under the 2009 Agreement and $0.7 million was issued under the 2012 Agreement. The stand-by letters of credit outstanding at September 30, 2013 were collateralized by restricted cash of $4.7 million.

Litigation

Note 9 – Commitments and Contingencies, under the caption “Litigation” of our Annual Report on Form 10-K filed with the SEC on March 12, 2013, provides information on certain litigation in which we are involved. Unfavorable rulings, judgments, or settlement terms regarding these litigation matters could have a material adverse impact on our business, financial condition, results of operations, and cash flows. Although none of the litigation matters can be quantified with absolute certainty, we have established accruals covering exposure and relating to contingencies to the extent that they are reasonably estimable and probable based on available facts. Except for the updates below, there have been no material developments to these matters; therefore, we have made no changes to our accruals in the first nine months of 2013.

On September 4, 2013, the parties in Radakovich v. Energy Recovery, Inc., Case No. 2:11-cv-13443 in the United States District Court for the Eastern District of Michigan, presented oral arguments on their respective motions for summary judgment. To date, the court has not ruled on the motions.

On October 7, 2013, the evidentiary proceedings concluded in the matter of Morgan Technical Ceramics Auburn Inc. v. Energy Recovery, Inc., Case No. RG11-608399. The court has not yet made any findings of fact.

In addition to the above litigation matters, we are a defendant in a lawsuit filed by one of our competitors on October 4, 2013, entitled “Fluid Equipment Development Co., LLC, d/b/a FEDCO of Michigan v. Energy Recovery, Inc.” in the U.S. District Court for the Eastern district of Michigan (Southern Division). The complaint alleges false advertising under federal and Michigan state statutes based on claims made by us related to certain of our products. Plaintiffs seek injunctive relief and as of yet, unspecified damages, attorney’s fees, and litigation costs. We intend to defend this case vigorously and believe that we have meritorious defenses against the suit, although we cannot guarantee that we will ultimately prevail.

Note 10 — Business Segment and Geographic Information

We manufacture and sell high-efficiency energy recovery devices and pumps as well as related services under one reportable segment. Our chief operating decision-maker is the chief executive officer (“CEO”). The CEO reviews financial information presented on a consolidated basis for purposes of making operating decisions and assessing financial performance. Accordingly, we have concluded that we have one reportable segment.

The following geographic information includes net revenue to our domestic and international customers based on the customers’ requested delivery locations, except for certain cases in which the customer directed us to deliver our products to a location that differs from the known ultimate location of use. In such cases, the ultimate location of use, rather than the delivery location, is reflected in the table below (in thousands, except percentages):

Note 12 — Fair Value Measurements

The authoritative guidance for measuring fair value prioritizes the inputs used into the following hierarchy:

Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2 — Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and

Level 3 — Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions that market participants would use in pricing.

The carrying values of cash and cash equivalents, restricted cash, accounts receivable, unbilled receivables, accounts payable, and other accrued expenses approximate fair value due to the short-term maturity of those instruments. For our investments in available-for-sale securities, if quoted prices in active markets for identical investments are not available to determine fair value (Level 1), then we use quoted prices for similar assets or inputs other than quoted prices that are observable either directly or indirectly (Level 2). The investments included in Level 2 consist primarily of certificates of deposits; commercial paper; and municipal, corporate, and agency obligations. The carrying amount of the contingent consideration arising from our acquisition of Pump Engineering, LLC is measured at fair value on a recurring basis using unobservable inputs in which little or no market activity exists (Level 3). The estimated fair value of the contingent consideration is determined based entirely on management’s assessment of the weighted probability of payment under various scenarios.

The fair value of financial assets and liabilities measured on a recurring basis for the indicated periods was as follows (in thousands):

	September 30, 2013		Level 1 Inputs		Level 2 Inputs		Level 3 Inputs

As of December 31, 2012, we had assets held for sale of $1.3 million related to our Michigan manufacturing facility. The assets included a building and land that was classified as held for sale at December 31, 2011 in connection with our restructuring plan to consolidate our North American operations and transfer all manufacturing operations to San Leandro, California. The fair value of these assets was determined based on Level 2 inputs, primarily sales data for similar properties in the area.

The assets were sold in September 2013. Net proceeds from the sale totaled $1.2 million, resulting in a loss on sale of $140,000. As the assets were part of the restructuring plan, the loss on sale was reported in the Condensed Consolidated Statement of Operations as a restructuring charge in the third quarter of 2013. Additional changes related to this asset during the nine months ended September 30, 2013 included an impairment loss of $44,000 prior to the sale during the second quarter of 2013.

Overview

We are in the business of designing, developing, and manufacturing energy recovery devices that harness the reusable energy from industrial fluid flows and pressure cycles. Our company was founded in 1992, and we introduced the initial version of our Pressure Exchanger^® energy recovery device in early 1997. In December 2009, we acquired Pump Engineering, LLC, which manufactured centrifugal energy recovery devices known as turbochargers as well as high-pressure pumps.

Our revenue is principally derived from the sale of our energy recovery devices. We also derive revenue from the sale of our high-pressure and circulation pumps that we manufacture and sell in connection with our energy recovery devices for use in desalination plants. Additionally, we receive incidental revenue from the sale of spare parts and services, including start-up and commissioning services that we provide to our customers.

A significant portion of our net revenue typically has been generated from sales to a limited number of large engineering, procurement, and construction, or EPC, firms that are involved with the design and construction of large desalination plants. Sales to these firms often involve a long sales cycle that can range from nine to 16 months, and in some cases, up to 24 months. A single large desalination project can generate an order for numerous energy recovery devices and generally represents a significant revenue opportunity. We also sell our devices to many small- to medium-sized original equipment manufacturers, or OEMs, which commission smaller desalination plants, order fewer energy recovery devices per plant, and have shorter sales cycles. In the oil and gas market, we have installed devices as part of pilot projects, and new devices are pending installation with major oil and gas customers worldwide. We have not recognized any revenue from shipments of energy recovery devices for oil and gas customers.

Due to the fact that a single order for our energy recovery devices by a large EPC firm for a particular plant may represent significant revenue, we often experience substantial fluctuations in net revenue from quarter to quarter and from year to year. Historically, our EPC customers tended to order a significant amount of equipment for delivery in the fourth quarter, and as a result, a significant portion of our annual sales occurred during that quarter. During the fourth quarter of 2012, five large mega-project shipments contributed to a significant increase in net revenue. The fourth quarter of 2013 is expected to follow the same trend, with a significant increase in mega-project shipments and therefore a significant increase in net revenue during the fourth quarter of the current year.

A limited number of our customers account for a substantial portion of our net revenue and accounts receivable. Revenue from customers representing 10% or more of net revenue varies from period to period. For the three months ended September 30, 2013, UNI E&T Co Ltd., Qingdao FTZ Gem–In International, and Hyflux Ltd. accounted for 17%, 16%, and 10%, respectively, of our net revenue. For the nine months ended September 30, 2013, no customer accounted for 10% or more of our net revenue. For the three months ended September 30, 2012, I.V.M. Minrav Sadyt (a consortium of Minrav Holdings, Ltd and Sadyt, a Valoriza Agua company) and Via Maris Desalination (a Global Environmental Solutions (GES) company) accounted for 38% and 10%, respectively, of our net revenue. For the nine months ended September 30, 2012, I.V.M. Minrav Sadyt and Southern Seawater JV (a joint venture of Tecnicas Reunidas Australia Pty Ltd, Valoriza Water Australia Pty Ltd, A.J. Lucas Operations Pty Ltd, and Worley Parsons Services Pty Ltd) accounted for 17% and 13%, respectively, of our net revenue. No other customer accounted for more than 10% of our net revenue during any of these periods.

During the three and nine months ended September 30, 2013 and 2012, most of our net revenue was attributable to sales outside of the United States. We expect sales outside of the United States to remain a significant portion of our net revenue for the foreseeable future.

Our condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States, or GAAP. These accounting principles require us to make estimates and judgments that can affect the reported amounts of assets and liabilities as of the date of the condensed consolidated financial statements as well as the reported amounts of revenue and expense during the periods presented. We believe that the estimates and judgments upon which we rely are reasonable based upon information available to us at the time that we make these estimates and judgments. To the extent that there are material differences between these estimates and actual results, our consolidated financial results will be affected. The accounting policies that reflect our more significant estimates and judgments and which we believe are the most critical to aid in fully understanding and evaluating our reported financial results are revenue recognition; allowance for doubtful accounts; allowance for product warranty; valuation of stock options; valuation and impairment of goodwill, long-lived assets, and acquired intangible assets; valuation of fair value of assets held for sale; useful lives for depreciation and amortization; valuation adjustments for excess and obsolete inventory; deferred taxes and valuation allowances on deferred tax assets; and evaluation and measurement of contingencies, including contingent consideration.

Net Revenue

Our net revenue decreased $5.6 million for the three months ended September 30, 2013 compared to the three months ended September 30, 2012. The decrease was primarily due to no mega-project shipments in the third quarter of 2013 compared to the third quarter of 2012, which contained over $5.0 million of revenue pertaining to mega-project shipments. Based on our current backlog of scheduled mega-project shipment dates, we anticipate strong revenue in the fourth quarter of 2013.

Although we operate under one segment, we categorize revenue based on the type of energy recovery device and its related products and services. The following table reflects revenue by product category and as a percentage of total net revenue (in thousands, except percentages):

	Three Months Ended September 30,
	2013				2012
PX devices and related products and services	$	3,554	73	%	$	8,663	83	%
Turbochargers, pumps, and related products and services		1,314	27	%		1,835	17	%
Net revenue	$	4,868	100	%	$	10,498	100	%

During the three months ended September 30, 2013 and 2012, a significant portion of our net revenue was attributable to sales outside of the United States. Revenue attributable to domestic and international sales as a percentage of net revenue was as follows:

	Three Months Ended September 30,
	2013			2012
Domestic revenue		16	%		12	%
International revenue		84	%		88	%
Net revenue		100	%		100	%

Gross Profit

Gross profit represents our net revenue less our cost of revenue. Our cost of revenue consists primarily of raw materials, personnel costs (including share-based compensation), manufacturing overhead, warranty costs, depreciation expense, and manufactured components. We achieved significant improvement in key profitability drivers, as gross profit as a percentage of net revenue increased to 60% for the three months ended September 30, 2013 compared to 55% for the three months ended September 30, 2012, despite lower revenue.

The increase in gross profit as a percentage of net revenue for the three months ended September 30, 2013 as compared to the same period of last year was primarily due to substantial cost reduction efforts over the last two years, that include plant consolidation, vertical integration, targeted cost-out and value engineering exercises, and efficiency-enhancing initiatives to achieve lower unit costs and better production yields. The increases in total gross profit were slightly offset by a product mix shift that favored turbochargers and pumps over PX devices. The unfavorable product mix shift caused a decrease in total gross profit as turbochargers and pumps have a lower gross profit margin compared to PX devices.

Future gross profit is highly dependent on the product and customer mix of our net revenue, overall market demand and competition, and the volume of production in our manufacturing plant that determines our operating leverage. Accordingly, we are not able to predict our future gross profit levels with certainty. We do believe, however, that the current levels of gross profit margin are sustainable and improvable to the extent that volume continues to grow; our product mix favors PXdevices; pricing remains stable; and we continue to realize cost savings through production efficiencies and enhanced yields.

Manufacturing average headcount increased to 44 in the third quarter of 2013 from 41 in the third quarter of 2012.

Share-based compensation expense included in cost of revenue was $18,000 and $25,000 for the three months ended September 30, 2013 and 2012, respectively.

General and Administrative Expense

General and administrative (“G&A”) expense decreased by $200,000, or 5%, to $3.6 million for the three months ended September 30, 2013 from $3.8 million for the three months ended September 30, 2012. As a percentage of net revenue, G&A expense increased to 74% for the three months ended September 30, 2013 from 36% for the three months ended September 30, 2012 primarily due to significantly lower net revenue offset by lower G&A expense for the current period.

G&A average headcount increased to 28 in the third quarter of 2013 from 27 in the third quarter of 2012.

Of the $200,000 decrease in G&A expense, $288,000 related to compensation and employee-related benefits and $73,000 related to professional fees and other services. These decreases were offset by increases of $77,000 related to occupancy costs, $51,000 related to bad debt expense, and $33,000 related to other G&A expenses.

Share-based compensation expense included in G&A expense was $339,000 and $440,000 for the three months ended September 30, 2013 and 2012, respectively.

Sales and Marketing Expense

Sales and marketing (“S&M”) expense decreased by $123,000, or 7%, to $1.7 million for the three months ended September 30, 2013 from $1.9 million for the three months ended September 30, 2012. As a percentage of net revenue, S&M expense increased to 36% for the three months ended September 30, 2013 from 18% for the three months ended September 30, 2012 primarily due to significantly lower net revenue offset by lower S&M expense in the current period.

S&M average headcount increased to 27 in the third quarter of 2013 from 23 in the third quarter of 2012.

Of the $123,000 decrease in S&M expense, $340,000 related to commissions for sales representatives primarily due to lower sales revenue. This decrease was offset by increases of $156,000 related to compensation and employee-related benefits, $33,000 related to marketing costs, and $28,000 related to occupancy and other S&M expenses.

Share-based compensation expense included in S&M expense was $123,000 and $94,000 for the three months ended September 30, 2013 and 2012, respectively.

We anticipate that our S&M expenses will increase in the future as we continue to market and sell new technologies for industries outside of seawater desalination and the current market for desalination grows.

Research and Development Expense

Research and development (“R&D”) expense decreased by $468,000, or 31%, to $1.0 million for the three months ended September 30, 2013 from $1.5 million for the three months ended September 30, 2012. As a percentage of net revenue, R&D expense increased to 21% for the three months ended September 30, 2013 from 14% for the three months ended September 30, 2012 primarily due to significantly lower net revenue offset by lower R&D expense in the current period.

R&D average headcount remained the same at 16 in both the third quarter of 2013 and the third quarter of 2012.

Of the $468,000 decrease in R&D expense for the three months ended September 30, 2013, $280,000 related to R&D costs, $170,000 related to outside consulting and professional fees, $15,000 related to compensation and other employee benefits, and $3,000 related to occupancy and other R&D expenses.

Share-based compensation expense included in R&D expense was $50,000 and $30,000 for the three months ended September 30, 2013 and 2012, respectively.

We anticipate that our R&D expense will increase in the future as we continue to advance our existing technologies and develop new energy recovery and efficiency-enhancing solutions for markets outside of seawater desalination.

Amortization of Intangible Assets

Amortization of intangible assets is primarily related to finite-lived intangible assets acquired as a result of our purchase of Pump Engineering, LLC in December 2009. Amortization expense decreased by $32,000, or 12%, to $230,000 for the three months ended September 30, 2013 from $262,000 for the three months ended September 30, 2012. The decrease was due to the impairment of the trademark intangible at December 31, 2012, for which no amortization expense was recorded during the three months ended September 30, 2013, and a change in the amortization amount for customer relationships related to the sum-of-the-years-digits amortization calculation.

Restructuring Charges

In 2011, we initiated a restructuring plan to consolidate our North American operations and transfer our Michigan-based operations to our manufacturing center and headquarters in San Leandro, California. In connection with this restructuring plan, we classified the land and building located in Michigan as assets held for sale at December 31, 2011. The land and building were sold in September 2013. Net proceeds from the sale totaled $1.2 million, resulting in a loss on sale for these assets of $140,000 recorded in restructuring charges during the three months ended September 30, 2013.

During the three months ended September 30, 2012, we recorded $167,000 against the restructuring plan. Of those charges, $164,000 related to the impairment of the assets held for sale to reflect the estimated fair value based on market studies of similar sales in the area at that time and $3,000 related to non-recurring charges associated with the restructuring plan.

Non-Operating Income (Expense), Net

Non-operating income (expense), net, decreased by $8,000 to income of $27,000 in the three months ended September 30, 2013 from income of $35,000 in the three months ended September 30, 2012. The decrease was due to $13,000 of unfavorable impacts from net foreign currency losses and lower interest income offset by $5,000 of favorable impacts from other income and lower interest expense.

Income Taxes

The income tax provision was $36,000 in the three months ended September 30, 2013 compared to a provision of $54,000 in the three months ended September 30, 2012. The tax provision for the three months ended September 30, 2013, consisted of tax expense of $68,000 related to the amortization of goodwill and state and other taxes offset by $32,000 related to the truing up of tax refunds receivable. As of December 31, 2012, a valuation allowance of approximately $12.7 million was established to reduce our deferred income tax assets to the amount expected to be realized. As such, no tax benefit related to our pre-tax loss was recognized for the three months ended September 30, 2013, as there was no change in our assessment of the amount of deferred income tax assets expected to be realized. For the three months ended September 30, 2012, the tax benefit recognized primarily related to the recognition of state tax refunds from prior-year returns.

Net Revenue

Our net revenue decreased $7.7 million for the nine months ended September 30, 2013 compared to the nine months ended September 30, 2012. Net revenue in the nine months ended September 2013, includes only $1.5 million in mega-project shipments whereas net revenue in the nine months ended September 2012, includes $10.5 million. This large decrease in net revenue was offset by increases in OEM and aftermarket sales. Based on our current backlog of scheduled mega-project shipment dates, we anticipate strong revenue in the fourth quarter of 2013.

	Nine Months Ended September 30,

As a percentage of net revenue, G&A expense increased to 56% for the nine months ended September 30, 2013 from 40% for the nine months ended September 30, 2012 primarily due to significantly lower net revenue and slightly higher G&A expense for the current period.

G&A average headcount increased to 28 in the nine months ended September 30, 2013 from 27 in the nine months ended September 30, 2012.

Of the $222,000 increase in G&A expense, $145,000 related to bad debt expense, $75,000 related to professional fees and other services, and $63,000 related to other G&A costs. These increases were offset by decreases of $25,000 related to compensation and other employee benefits, $19,000 in occupancy costs, and $17,000 related to insurance and other taxes.

Share-based compensation expense included in G&A expense was $1.2 million and $1.5 million for the nine months ended September 30, 2013 and 2012, respectively.

Sales and Marketing Expense

Sales and marketing (“S&M”) expense increased by $493,000, or 10%, to $5.6 million for the nine months ended September 30, 2013 from $5.1 million for the nine months ended September 30, 2012. As a percentage of net revenue, S&M expense increased to 28% for the nine months ended September 30, 2013 from 19% for the nine months ended September 30, 2012 primarily due to significantly lower net revenue and higher S&M expense in the current period.

S&M average headcount increased to 26 in the nine months ended September 30, 2013 from 24 in the nine months ended September 30, 2012.

Of the $493,000 increase in S&M expense for the nine months ended September 30, 2013, $514,000 related to marketing costs associated with the Company’s rebranding initiative and market research, $305,000 related to compensation and employee-related benefits, and $113,000 related to occupancy and other costs. These increases were offset by $439,000 related to commissions for sales representatives due to lower revenue.

Share-based compensation expense included in S&M expense was $358,000 and $434,000 for the nine months ended September 30, 2013 and 2012, respectively.

Research and Development Expense

Research and development (“R&D”) expense increased by $191, 000, or 6%, to $3.2 million for the nine months ended September 30, 2013 compared to the nine months ended September 30, 2012. As a percentage of net revenue, R&D expense increased to 16% for the nine months ended September 30, 2013 from 11% for the nine months ended September 30, 2012 primarily due to significantly lower net revenue and higher R&D expense in the current period.

We anticipate that our R&D expenses will increase in the future as we continue to advance our existing technologies and develop new energy recovery and efficiency-enhancing solutions for markets outside of seawater desalination.

Amortization of Intangible Assets

Amortization of intangible assets is primarily related to finite-lived intangible assets acquired as a result of our purchase of Pump Engineering, LLC in December 2009. Amortization expense decreased by $94,000, or 12%, to $691,000 for the nine months ended September 30, 2013 from $785,000 for the nine months ended September 30, 2012. The decrease was due to the impairment of the trademark intangible at December 31, 2012, for which no amortization expense was recorded during the nine months of 2013, and a change in the amortization amount for customer relationships related to the sum-of-the-years-digits amortization calculation.

Net proceeds from the sale totaled $1.2 million, resulting in a loss on sale for these assets of $140,000 recorded in restructuring charges during the nine months ended September 30, 2013. Additional restructuring charges included an impairment loss on assets held for sale of $44,000.

During the nine months ended September 30, 2012, we recorded $277,000 related to the restructuring plan. Of these charges, $243,000 related to the impairment of the land and building to reflect the fair value based on market studies of similar sales in the area and $34,000 related to other non-recurring charges associated with the restructuring plan.

Non-Operating Income (Expense), Net

Non-operating income (expense), net, decreased by $14,000 to income of $79,000 in the nine months ended September 30, 2013 from income of $93,000 in the nine months ended September 30, 2012. The decrease was due to lower interest and other income of $61,000 offset by $46,000 of favorable impacts from net foreign currency losses compared to the prior period and lower interest expense.

Income Taxes

The income tax provision was $258,000 in the nine months ended September 30, 2013 compared to a benefit of $253,000 in the nine months ended September 30, 2012. The tax provision for the nine months ended September 30, 2013, consisted of tax expense of $167,000 related to the amortization of goodwill; $97,000 related to our federal tax true-up; and $26,000 of state and other taxes. The tax expense was offset by $32,000 related to the truing up of tax refunds receivable. As of December 31, 2012, a valuation allowance of approximately $12.7 million was established to reduce our deferred income tax assets to the amount expected to be realized. As such, no tax benefit related to our pre-tax loss was recognized for the nine months ended September 30, 2013, as there was no change in our assessment of the amount of deferred income tax assets expected to be realized. For the nine months ended September 30, 2012, the tax benefit recognized primarily related to the recognition of state tax refunds from prior-year returns.

Liquidity and Capital Resources

Overview

Our primary source of cash historically has been proceeds from the issuance of common stock, customer payments for our products and services, and borrowings under our credit facility. From January 1, 2005 through September 30, 2013, we issued common stock for aggregate net proceeds of $84.0 million, excluding common stock issued in exchange for promissory notes. The proceeds from the sales of common stock have been used to fund our operations and capital expenditures.

As of September 30, 2013, our principal sources of liquidity consisted of unrestricted cash and cash equivalents of $15.8 million that are invested primarily in money market funds along with short- and long-term investments of $19.1 million that are primarily invested in marketable debt securities. We invest cash not needed for current operations predominantly in high-quality, investment-grade marketable debt instruments with the intent to make such funds available for operating purposes as needed.

We have unbilled receivables pertaining to customer contractual holdback provisions, whereby we invoice the final installment due under a sales contract up to 24 months after the product has been delivered to the customer and revenue has been recognized. The customer holdbacks represent amounts intended to provide a form of security to the customer rather than a form of long-term financing. Accordingly, these receivables have not been discounted to present value. At September 30, 2013 and December 31, 2012, we had $1.0 million and $5.9 million of current and non-current unbilled receivables, respectively.

In 2009, we entered into a loan and security agreement (the “2009 Agreement”) with a financial institution. The 2009 Agreement, as amended, provided a total available credit line of $16.0 million. Under the 2009 Agreement, we were allowed to draw advances of up to $10.0 million on a revolving line of credit or utilize up to $15.9 million as collateral for stand-by letters of credit, provided that the aggregate of the outstanding advances and collateral did not exceed the total available credit line of $16.0 million. Advances under the revolving line of credit incurred interest based on a prime rate index or on LIBOR plus 1.375%. The amended 2009 Agreement also required us to maintain a cash collateral balance equal to at least 101% of the face amount of all outstanding stand-by letters of credit collateralized by the line of credit and 100% of the amount of all outstanding advances.

During the periods presented, we provided certain customers with stand-by letters of credit to secure our obligations for the delivery and performance of products in accordance with sales arrangements. Some of these stand-by letters of credit were issued under our 2009 Agreement. The stand-by letters of credit generally terminate within 12 to 48 months and, in some cases up to 65 months, from issuance. As of September 30, 2013, the amounts outstanding on stand-by letters of credit collateralized under our 2009 Agreement totaled approximately $4.0 million, and restricted cash related to the stand-by letters of credit issued under the 2009 Agreement was approximately $4.0 million. The 2009 Agreement expired at the end of May 2012.

In June 2012, we entered into a loan agreement (the “2012 Agreement”) with another financial institution. The 2012 Agreement provides for a total available credit line of $16.0 million. Under the 2012 Agreement, we are allowed to draw advances not to exceed, at any time, $10.0 million as revolving loans. The total stand-by letters of credit issued under the 2012 Agreement may not exceed the lesser of the $16.0 million credit line or the credit line minus all outstanding revolving loans. At no time may the aggregate of the revolving loans and stand-by letters of credit exceed the total available credit line of $16.0 million. Revolving loans may be in the form of a base rate loan that bears interest equal to the prime rate plus 0% or a Eurodollar loan that bears interest equal to the adjusted LIBO rate plus 1.25%. Stand-by letters of credit are subject to customary fees and expenses for issuance or renewal. The unused portion of the credit facility is subject to a fee in an amount equal to 0.25% per annum of the average unused portion of the revolving line.

The 2012 Agreement also requires us to maintain a cash collateral balance equal to 101% of all outstanding advances and all outstanding stand-by letters of credit collateralized by the line of credit. The 2012 Agreement matures on June 5, 2015 and is collateralized by substantially all of our assets. As of September 30, 2013, there were no advances drawn under the 2012 Agreement’s line of credit. The amounts outstanding on stand-by letters of credit collateralized under the 2012 Agreement totaled approximately $0.7 million, and restricted cash related to the stand-by letters of credit issued under the 2012 Agreement was approximately $0.7 million as of September 30, 2013.

In 2012, our credit card vendor required us to restrict cash for outstanding credit card balances. Accordingly, we have restricted $315,000 of cash for credit card balances as of September 30, 2013.

Cash Flows from Operating Activities

Net cash provided by (used in) operating activities was $2.7 million and $(2.0) million for the nine months ended September 30, 2013 and 2012, respectively. For the nine months ended September 30, 2013, a net loss of $(9.8) million was adjusted to $(4.3) million by non-cash items totaling $5.5 million. For the nine months ended September 30, 2012, a net loss of $(6.1) million was adjusted to $60,000 by non-cash items totaling $6.1 million. Non-cash adjustments primarily include depreciation and amortization, share-based compensation expense, provisions for doubtful accounts and warranty reserves, restructuring charges, amortization of premiums/discounts on investments, and adjustments to inventory reserves.

The net cash impact from changes in assets and liabilities was approximately $7.0 million and $(2.1) million for the nine months ended September 30, 2013 and 2012, respectively. Net changes in assets and liabilities are primarily attributable to changes in inventory as a result of the timing of order processing and product shipments; changes in accounts receivable, deferred revenue, and unbilled receivables as a result of collections for large projects and the timing of invoices; changes in prepaid expenses as a result of the receipt of tax refunds; and changes in accrued liabilities and accounts payable as a result of the timing of payments to employees, vendors, and other third parties.

Cash Flows from Investing Activities

Net cash (used in) provided by investing activities was $(4.0) million and $5.9 million for the nine months ended September 30, 2013 and 2012, respectively. The decrease of $9.9 million in cash flows from investing activities for the nine months ended September 30, 2013 compared to the nine months ended September 30, 2012 was primarily due to an increase in the purchase of marketable securities and a decrease in maturities of marketable securities of $12.5 million. These were offset by proceeds from the sale of assets held for sale of $1.2 million, a decrease in capital expenditures of $1.0 million and an increase of $0.5 million due to the release of restricted cash.

Cash Flows from Financing Activities

Net cash provided by (used in) financing activities was $407,000 and $(4.2) million for the nine months ended September 30, 2013 and 2012, respectively. The $4.6 million increase in net cash provided by financing activities was primarily due to a $4.0 million decrease of cash used to repurchase common stock for treasury, a $418,000 increase in cash received for the issuance of common stock due to option and warrant exercises, and a $143,000 decrease in debt and capital lease payments as a result of paying off two capital leases and an equipment promissory note in 2012 as well as our last capital lease in 2013.

Liquidity and Capital Resource Requirements

We may enter into potential material investments in, or acquisitions of, complementary businesses, services, or technologies, which could require us to seek additional equity or debt financing. However, if we do not invest in, or make any acquisitions of, complementary businesses, services, or technologies, we believe that our existing cash balances and cash generated from operations will be sufficient to meet our anticipated capital requirements for at least the next twelve months. We may need to raise additional capital or incur additional indebtedness to continue to fund our operations in the future. Our future long-term capital requirements will depend on many factors, including our rate of revenue growth, if any, the expansion of sales and marketing and research and development activities, the timing and extent of our expansion into new geographic territories, the timing of new product introductions, the continuing market acceptance of our products, and any possible acquisitions that we might complete to advance our strategy. Additional funds may not be available on terms favorable to us or at all.

Contractual Obligations

We lease facilities under fixed non-cancellable operating leases that expire on various dates through 2019. The total of the future minimum lease payments under these leases as of September 30, 2013 was $9.6 million. For additional information, see Note 9 — “Commitments and Contingencies” to the unaudited condensed consolidated financial statements.

In the course of our normal operations, we also enter into purchase commitments with our suppliers for various raw materials and components parts. The purchase commitments covered by these arrangements are subject to change based on sales forecasts for future deliveries. As of September 30, 2013, we had approximately $3.0 million of cancellable open purchase order arrangements related primarily to materials and parts.

We have agreements with guarantees or indemnity provisions that we have entered into with customers and others in the ordinary course of business. Based on our historical experience and information known to us as of September 30, 2013, we believe that our exposure related to these guarantees and indemnities was not material.

Off-Balance Sheet Arrangements

During the periods presented, we did not have any relationships with unconsolidated entities or financial partnerships such as entities often referred to as structured finance or special purpose entities that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Recent Accounting Pronouncements

See Note 1 — “The Company and Summary of Significant Accounting Policies” to the condensed consolidated financial statements regarding the impact of certain recent accounting pronouncements on our condensed consolidated financial statements.

Item 3. — Quantitative and Qualitative Disclosure About Market Risk

The information in this section should be read in connection with the information on financial market risk related to changes in currency exchange rates and interest rates in Part II, Item 7A, “Quantitative and Qualitative Disclosure About Market Risk,” in our Annual Report on Form 10-K for the year ended December 31, 2012.

Foreign Currency Risk

Currently, the majority of our revenue contracts have been denominated in United States Dollars. In some circumstances, we have priced certain international sales in Euros.

As we expand our international sales, we expect that a portion of our net revenue could continue to be denominated in foreign currencies. As a result, our cash and cash equivalents and operating results could be increasingly affected by changes in exchange rates. Our international sales and marketing operations incur expenses that are denominated in foreign currencies. These expenses could be materially affected by currency fluctuations. Our exposures are to fluctuations in exchange rates for the United States Dollar versus the Euro. Changes in currency exchange rates could adversely affect our consolidated operating results or financial position. Additionally, our international sales and marketing operations maintain cash balances denominated in foreign currencies. To decrease the inherent risk associated with translation of foreign cash balances into our reporting currency, we have not maintained excess cash balances in foreign currencies. We have not hedged our exposure to changes in foreign currency exchange rates because expenses and cash balances in foreign currencies have been insignificant to date and exchange rate fluctuations have had little impact on our operating results and cash flows.

Interest Rate Risk

We have an investment portfolio of fixed income marketable debt securities, including amounts classified as cash equivalents, short-term investments, and long-term investments. At September 30, 2013, our short- and long-term investments totaled $19.1 million. The primary objective of our investment activities is to preserve principal and liquidity while at the same time maximizing yields without significantly increasing risk. We invest primarily in high-quality, short- and long-term debt instruments of the U.S. government and its agencies as well as high-quality corporate and municipal issuers. These investments are subject to interest rate fluctuations and will decrease in market value if interest rates increase. To minimize the exposure due to adverse shifts in interest rates, we maintain investments with an average maturity of less than three years. A hypothetical 1% increase in interest rates would have resulted in an approximately $223,000 decrease in the fair value of our fixed-income debt securities as of September 30, 2013.

Concentration of Credit Rate Risk

Our investments in marketable debt securities are subject to potential loss of value due to counterparty credit risk. To minimize this risk, we invest pursuant to a Board-approved investment policy. The policy mandates high-credit-rating requirements and restricts our exposure to any single corporate issuer or sector by imposing concentration limits.

Item 4. — Controls and Procedures.

(a) Evaluation of disclosure controls and procedures. Under the supervision and with the participation of our management, including the President and Chief Executive Officer and the Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934 as of the end of the period covered by this report.

Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that these disclosure controls and procedures are effective.

(b) Changes in internal controls. We implemented a new enterprise resource planning (“ERP”) system effective July 1, 2013. We believe that the new ERP system will simplify and strengthen our internal control over financial reporting.

With the exception of our new ERP system, there have been no changes in our internal control over financial reporting during the quarter ended September 30, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. — Legal Proceedings

For an update on the litigation matters previously disclosed in our Form 10-K, as well as new litigation matters, see Note 9 – Commitments and Contingencies, under the caption “Litigation” of this quarterly report on Form 10-Q.

Item 1A. — Risk Factors

With the exception of the following updates, there have been no material changes in our risk factors from those disclosed in Part I, Item 1A, in our Annual Report on Form 10-K filed on March 12, 2013.

We may experience difficulties implementing our enterprise resource planning system.

In 2012, we initiated a project to upgrade our enterprise resource planning (“ERP”) system to streamline our business processes and allow for cost-efficient scalability, flexibility, and improved management reporting and analysis. On July 1, 2013, we launched our new ERP system. We anticipate that our new ERP system will accommodate our future needs as we continue to evolve our business in a changing marketplace. Our new ERP system is critical to our ability to accurately maintain books and records, record transactions, provide important information to our management, and prepare our financial statements. The design and implementation of the new ERP system has required the investment of significant financial and human resources. While we have not experienced insurmountable difficulties thus far during the stabilization period, which we expect to last for the remainder of the year, we may encounter difficulties, and we cannot guarantee that the new ERP system will support our business operations. Any disruptions, delays, or deficiencies in the design and stabilization of the new ERP system could adversely affect our ability to process orders, ship products, provide services and customer support, send invoices and track payments, fulfill contractual obligations, or otherwise operate our business, which could, in turn, adversely affect our results of operations, financial condition, and cash flows as well as our internal control over financial reporting.

We may see an increase in litigation as a result of increased competition and entrance into new markets.

As competition increases in the desalination market and as we enter into new market segments, such as oil & gas, we may see an increase in litigation, both asserted against us or by us against competitors. Cost associated with litigation, as well as the nature of the claims asserted in potential litigation, may have a material adverse impact on our results of operations and financial condition.

We may experience reputational damage if pilot projects do not materialize or perform as we expect or we are unable to use these pilot projects as showcases to drive new business and growth.

Entry into new market segments, such as oil & gas requires proof-of-concept and pilot projects to demonstrate commercial viability of solution offering to potential customers and other market participants. If we are unable to penetrate the market with these projects or our projects do not perform as expected, our reputation, in regard to new product introduction, may suffer. Additionally, if we are unable, for any reason, to use initial projects as customer showcases, it may affect our growth into these markets. Issues with facility access, confidentiality, or overall project performance may affect our ability to showcase any of our projects to new potential customers.
