ITEM 1.

BUSINESS

General

OSI Systems, Inc., together with its subsidiaries, is a vertically integrated designer and manufacturer of specialized electronic systems and components for critical applications. We sell our products in diversified markets, including homeland security, healthcare, defense and aerospace. Our company was incorporated in 1987 in California. Our principal office is located at 12525 Chadron Avenue, Hawthorne, California 90250.

We have three operating divisions: (a) Security, providing security and inspection systems; (b) Healthcare, providing patient monitoring, diagnostic cardiology and anesthesia systems; and (c) Optoelectronics and Manufacturing, providing specialized electronic components for the Security and Healthcare divisions, as well as for applications in the defense and aerospace markets, among others.

Through our Security division, we design, manufacture and market security and inspection systems worldwide to end users under the “Rapiscan Systems” trade name. Rapiscan Systems products are used to inspect baggage, cargo, vehicles and other objects for weapons, explosives, drugs and other contraband, and to screen people. These products are also used for the safe, accurate and efficient verification of cargo manifests for the purpose of assessing duties and monitoring the export and import of controlled materials. Rapiscan Systems products fall into four categories: baggage and parcel inspection, cargo and vehicle inspection, hold (checked) baggage screening and people screening.

Through our Healthcare division, we design, manufacture and market patient monitoring, diagnostic cardiology and anesthesia systems worldwide to end users primarily under the “Spacelabs” trade name. These products are used by care providers in critical care, emergency and perioperative areas within hospitals as well as physicians offices, medical clinics and ambulatory surgery centers. We also offer centralized cardiac safety core lab services in connection with clinical trials by or on behalf of pharmaceutical companies and clinical research organizations.

Through our Optoelectronics and Manufacturing division, we design, manufacture and market optoelectronic devices and value-added manufacturing services worldwide for use in a broad range of applications, including aerospace and defense electronics, security and inspection systems, medical imaging and

diagnostics, computed tomography (CT), fiber optics, telecommunications, gaming, office automation, computer peripherals and industrial automation. We sell our optoelectronic devices under the “OSI Optoelectronics” trade name and perform our value-added manufacturing services under the “OSI Electronics” trade name. We provide our optoelectronic devices and value-added manufacturing services to original equipment manufacturers, as well as to our own Security and Healthcare divisions. Our Optoelectronics and Manufacturing division also designs toll and traffic management systems under the “OSI LaserScan” trade name and systems for measuring bone density under the “Osteometer” trade name.

In fiscal 2008, revenues from the Security division amounted to $225.8 million, or approximately 36% of our revenues; revenues from the Healthcare division amounted to $256.7 million, or approximately 41% of our revenues; and third-party revenues from the Optoelectronics and Manufacturing division amounted to $140.6 million, or approximately 23% of revenues. Additional information concerning reporting segments is available in Note 15 to our Consolidated Financial Statements.

Industry Overview

We sell our security and inspection systems and patient monitoring, diagnostic cardiology and anesthesia systems primarily to end-users, while we design and manufacture our optoelectronic devices and value-added subsystems primarily for original equipment manufacturers.

Security. A variety of technologies are currently used worldwide in security and inspection applications, including computed tomography, transmission and backscatter x-ray, metal detection, trace detection and x-ray, gamma-ray, passive millimeter wave, and neutron analysis. We believe that the market for security and inspection products will continue to be affected by the threat of terrorist incidents and by new government mandates and appropriations for security and inspection products in the United States and internationally.

The September 11, 2001 terrorist attacks on the World Trade Center and the Pentagon using hijacked airliners led to nationwide shifts in transportation and facilities security policies. Shortly following these attacks, Congress passed the Aviation and Transportation Security Act and integrated many U.S. security-related agencies, including the Federal Aviation Administration, into the U.S. Department of Homeland Security. Under its directive from Congress, the U.S. Department of Homeland Security has since undertaken numerous initiatives to prevent terrorists from entering the country, hijacking airliners, and obtaining and trafficking in weapons of mass destruction and their components, to secure sensitive U.S. technologies and to identify and screen high-risk cargo containers before they are loaded onto vessels destined for the U.S., among others. These initiatives, known, for example, as the Strategic Border Initiative, the Customs-Trade Partnership Against Terrorism and the U.S. Customs and Border Protection Container Security Initiative, have resulted in an increased demand for security and inspection products both in the United States and other nations.

Government sponsored initiatives in the United States, such as the U.S. Customs and Border Protection Container Security Initiative and the Customs-Trade Partnership Against Terrorism, have also stimulated security programs in other areas of the world because the U.S initiatives call on other nations to bolster their port security strategies, including acquiring or improving their security and inspection equipment. The international market for non-intrusive inspection equipment, therefore, continues to expand as countries that ship goods directly to the United States are required to improve their security infrastructure.

The U.S. Congress recently passed legislation that mandated the inspection of international maritime cargo destined for the United States, domestic civil aviation cargo, and for radiological and nuclear threats in cargo entering the United States. Certain of our cargo and vehicle inspection systems are already being used internationally and by the U.S. government to comply with these mandates. In addition, following recommendations outlined in the “9/11 Commission Report,” issued by the National Commission on Terrorist Attacks Upon the United States, the U.S. Department of Homeland Security will require the screening of all cargo carried on passenger airlines by 2010.

Furthermore, the U.S. Department of Homeland Security’s Science and Technology Directorate has supported the development of new security inspection technologies and products. Our Security division participates in a number of such research and development efforts, including projects to develop new technologies for radiation and nuclear materials detection, aviation screening and suicide bomber detection. The Science and Technology Directorate has also initiated programs for the development of technologies capable of protecting highways, railways and waterways from terrorist attack.

In addition, the U.S. Department of Defense has also begun to invest more heavily in technologies and services that screen would-be attackers before they are able to harm U.S. and allied forces.

Similar initiatives by international organizations such as the European Union have also resulted in a growing worldwide demand for airline, cargo, port and border inspection technologies. For example, the European Union is expected to issue uniform performance standards for people, cargo, mail and parcel and hold baggage screening systems as well as new directives related specifically to maritime security. We anticipate that the promulgation of these new standards will establish performance baselines against which our Security division will be able to direct certain of its research and development spending and market its products to customers located in the European Union.

As a result of these and other changes, sales of our security and inspection products have grown as compared to pre-September 11, 2001 levels. Major projects recently installed or currently underway include system installations at airports, ports and border crossings, government and military facilities and other locations in the United States and throughout the world. These projects contain various inspection product offerings. We anticipate that there may be growing demand from governments and commercial enterprises for increasingly sophisticated screening solutions in the future.

Healthcare. Healthcare is a rapidly growing sector throughout most of the world and especially in many Asian and Latin American economies. In much of the developed world, including in the United States and Europe, an aging population is also fueling growth.

Many factors such as a nursing shortage in the United States and Europe, stricter government requirements affecting the staffing and accountability and shrinking reimbursements from health insurance organizations are forcing healthcare providers to do more with less. Our Healthcare division designs, manufactures and markets products that respond to these new economic forces by helping hospitals reduce costs while maintaining or improving the quality of care their physicians and nurses are able to deliver.

We are a global manufacturer and distributor of patient monitoring and clinical networking solutions for use primarily in hospitals. We design, manufacture and market patient monitoring solutions for critical, emergency and perioperative care areas of the hospital, wired and wireless networks, ambulatory blood pressure monitors and clinical trials services, all aimed at providing caregivers with timely patient information. By making critical patient information more readily accessible both inside and outside the hospital, delays in decision-making can be reduced, length of stay can be shortened and treatment errors can be minimized.

We are a global manufacturer and distributor of anesthesia delivery systems, ventilators and vaporizers. We sell these products primarily to hospitals for use in operating rooms and anesthesia induction areas as well as in magnetic resonance imaging (MRI) facilities. In addition, as pharmaceutical companies develop new anesthesia agents for the worldwide market, or as generic alternatives to patented anesthesia formulas become available, we work closely with them to support their new product introductions. As a result, we also sell systems and components, such as anesthesia vaporizers and ventilators, directly to pharmaceutical companies and other manufacturers of anesthesia delivery systems.

In July 2006, we acquired Del Mar Reynolds, a global manufacturer and distributor of cardiac monitoring systems, including Holter recorders, ECG, stress systems and related software and services to hospitals. The acquired operations also included a core laboratory business that provides clinical trial services to pharmaceutical companies and to clinical research organizations. These operations have since been integrated into the Healthcare division’s diagnostic cardiology and clinical trial services businesses.

In October 2005, Spacelabs Healthcare, Inc., a subsidiary comprising the business operations of our Healthcare division, completed an initial public offering of approximately 20% of its total issued and outstanding common stock. The Spacelabs Healthcare shares traded under the ticker symbol “SLAB” on the AIM (formerly known as the Alternative Investment Market), a stock market administered by the London Stock Exchange. In the second quarter of fiscal 2007, we began repurchasing publicly-traded shares of Spacelabs Healthcare, increasing our ownership to 84% as of June 30, 2007. By December 31, 2007, we increased our ownership in Spacelabs Healthcare to 100% by repurchasing all remaining shares of Spacelabs Healthcare. Effective January 24, 2008, we cancelled Spacelabs Healthcare’s AIM listing.

Optoelectronics and Manufacturing. Our optoelectronic devices are used in a wide variety of applications such as satellites, laser guidance systems, range finders, computer peripherals and other applications that require the conversion of optical signals into electronic signals. Because optoelectronic devices and value-added subsystems can be used in a wide variety of measurement control and monitoring applications, they are also used in a broad array of industrial applications and are key components in the telecommunications and fiber optics industries. Historically, we have offered value-added manufacturing services to purchasers of our optoelectronic devices, including to our Security and Healthcare divisions. More recently, however, we have begun to expand such services by providing complete turn-key and box-build manufacturing services, in which we design, acquire materials, produce, test and supply electronic systems and components to purchasers of optoelectronic devices and to others.

We believe that recent advances in technology and reductions in the cost of key components of optoelectronic systems, including computer processing power and memory, have broadened the market by enabling the use of optoelectronic devices in a greater number of applications. In addition, we see a trend among original equipment manufacturers to increasingly outsource the design and manufacture of optoelectronic devices as well as value-added subsystems to fully-integrated, independent manufacturers, like us, who may have greater specialization, broader expertise and the flexibility to respond in shorter time periods than most original equipment manufacturers can accomplish in-house. We believe that our level of vertical integration, substantial engineering resources, expertise in the use and application of optoelectronic technology and low-cost international manufacturing operations enable us to compete effectively in the market for optoelectronic devices and for value-added manufacturing services.

We have also penetrated several related markets that depend on our optoelectronic technologies and electronics manufacturing capabilities. For example, we sell a series of high-speed photodetectors for use in fiber optic systems such as Gigabit Ethernet, Fiber Channel and other telecommunication and data communication applications. Through system engineering and product development, we also develop, manufacture and sell laser-based remote sensing devices that are used to detect and classify vehicles in toll and traffic management systems and dual energy absorptiometry peripheral bone densitometers that are used to measure bone density in individuals that may be at risk for developing osteoporosis.

Growth Strategy

We believe that one of our primary competitive strengths is our expertise in the cost-effective design and manufacture of specialized electronic systems and components for critical applications. As a result, we have leveraged, and intend to continue to leverage, such expertise and capacity to gain price, performance and agility advantages over our competitors in the security, healthcare and optoelectronics fields, and to translate such advantages into profitable growth in those fields. At the same time, we continually seek to identify new markets in which our core expertise and capacity will provide us with competitive advantages. Key elements of this strategy include:

Capitalizing on Global Reach. We operate from locations in North America, Asia and Europe. We view our international operations as providing an important strategic advantage over competitors. First, international manufacturing facilities allow us to take advantage of competitive labor rates and favorable tax regulations in order to be a low cost producer. Second, our international offices strengthen our sales and marketing efforts and our ability to service and repair our systems by providing direct access to growing foreign markets and to our existing international customer base. Third, multiple manufacturing locations allow us to reduce delivery times to our global customer base. In the future, we intend to develop new sources of manufacturing and sales capabilities to maintain and enhance the benefits of our international presence.

Capitalizing on Vertical Integration. Our vertical integration provides several advantages in each of our divisions. These advantages include reduced manufacturing and delivery times, lower costs due to our access to competitive international labor markets, direct sourcing of raw materials and quality control. We also believe that we offer significant added value to our customers by providing a full range of vertically-integrated services including component design and customization, subsystem concept design and application engineering, product prototyping and development, efficient pre-production and short-run and high volume manufacturing. We believe that our vertical integration differentiates us from many of our competitors and provides value to our customers who can rely on us to be an integrated supplier. We intend to continue to leverage our vertically integrated services to create greater value for our customers in the design and manufacture of our products.

Capitalizing on the Growing Market for Security and Inspection Systems. Heightened attentiveness to terrorist and other security threats may continue to drive growth in the market for security and inspection systems, not only in transportation security, but in facilities and event security. In addition, the trend toward increased international transportation of goods may result in growth in the market for cargo inspection systems that are capable of screening shipping containers for contraband and assisting customs officials in the verification of shipping manifests. Package screening by freight forwarders also represents a potential growing sector, as new regulations in Europe require such screening and awareness of the need for such screening grows in the U.S. We intend to continue to expand our sales and marketing efforts both domestically and internationally, and to capitalize on opportunities to replace, service and upgrade existing security installations. We also intend to continue to develop new security and inspection technologies, such as our real time tomography products, and may enhance and expand our current product offerings through selective acquisitions to better address new applications and security industry demands.

Improving and Complementing Existing Medical Technologies. We develop and market patient monitoring systems and diagnostic cardiology products, anesthesia delivery systems, ventilators and vaporizers that utilize patient monitoring technologies. As a result, we are able to market and sell many of our product offerings through shared sales channels and distribution networks. Our efforts to improve our existing medical technologies are focused on making patient information available to care providers both at the bedside as well as in other parts or even away from the hospital, thereby reducing time demands on physicians and nurses, enabling more rapid treatment decisions and improving patient care. Overall, our efforts at improving our existing medical diagnostic and anesthesia delivery technologies will also continue to concentrate on the development of devices that make it possible for institutions from large hospitals to small clinics and physicians’ offices to obtain accurate, precise, reliable and cost-effective results.

Selectively Entering New Markets. We intend to continue to selectively enter new markets that complement our existing capabilities in the design, development and manufacture of specialized electronic systems and components for critical applications such as security and inspection and patient monitoring, diagnostic cardiology and anesthesia systems. We believe that by manufacturing end products that rely on our existing technological capabilities, we will leverage our integrated design and manufacturing infrastructure to capture greater margins and to build a larger presence in new end markets that present attractive competitive dynamics. We intend to achieve this strategy through internal growth and through selective acquisitions.

Acquiring New Technologies and Companies. Our success depends in part on our ability to continually enhance and broaden our product offerings in response to changing technologies, customer demands and competitive pressures. We have developed expertise in our various lines of business and other areas through internal research and development efforts as well as through selective acquisitions. As a vertically integrated designer and manufacturer of specialized electronic systems and components for critical applications, we have, since our inception as a company, looked for acquisition opportunities to broaden our technological expertise and capabilities, lower our manufacturing costs or facilitate our entry into new markets.

Products and Technology

We design, develop, manufacture and sell products ranging from security and inspection systems to patient monitoring, diagnostic cardiology and anesthesia systems to discrete optoelectronic devices and value-added subsystems.

Security and Inspection Systems. We design, manufacture and market security and inspection systems worldwide to end users under the “Rapiscan Systems” trade name. Rapiscan Systems products are used to inspect baggage, cargo, people, vehicles and other objects for weapons, explosives, drugs and other contraband. These systems are also used for the safe, accurate and efficient verification of cargo manifests for the purpose of assessing duties and monitoring the export and import of controlled materials. Rapiscan Systems products fall into four categories: baggage and parcel inspection, cargo and vehicle inspection, hold (checked) baggage screening and people screening.

As a result of the terrorist attacks of September 11, 2001, and subsequent attacks in other locations worldwide, security and inspection products have increasingly been used at a wide range of facilities other than airports, such as border crossings, railway stations, seaports, cruise line terminals, government and military installations and nuclear facilities. As a result of the additional markets, we have successfully diversified our sales channels for security and inspection products.

Many of our security and inspection systems include dual- or multi-energy x-ray technology with computer software enhanced imaging technology to facilitate the detection of materials such as explosives, weapons, narcotics, currency or other contraband. While all x-ray systems produce a two-dimensional image of the contents of the inspected object, the dual-energy x-ray systems also measure the x-ray absorption of the inspected object’s contents at two x-ray energies to determine the atomic number, mass and other characteristics of the object’s contents. The various organic and inorganic substances in the inspected object appear to operators of the inspection systems in various colors and this visual information can be used to identify and differentiate the inspected materials. Our baggage and parcel inspection, cargo and vehicle inspection and hold baggage screening inspection systems range in size from compact tabletop systems to large systems comprising entire buildings in which trucks, shipping containers or pallets are inspected.

Our cargo and vehicle inspection applications, in which trucks, shipping containers, pallets and other large objects can be inspected, are designed in various configurations, including fixed-site, gantry, relocatable, portal and mobile systems. These products are primarily used to verify the contents of trucks or cargo containers and to detect the presence of contraband. They offer significant improvements over past methods of cargo screening, such as manual searches, as our cargo systems are faster, more thorough and do not subject the cargo to pilferage. Entire shipping containers or trucks containing densely packed goods can be screened rapidly.

Many of our cargo and vehicle inspection systems utilize ionizing radiation, such as high-energy x-ray or gamma-ray beams, in conjunction with digital imaging equipment, to non-intrusively inspect objects and present images to an inspector, showing shapes, sizes, locations and relative densities of the contents. Many of these systems, such as the Rapiscan Eagle line of products, which was designed and developed under contract with U.S. Customs and Border Protection and the U.S. Department of Defense, have been built to meet specific customer inspection requirements.

Other cargo and vehicle inspection products automatically and non-intrusively detect chemical signatures indicating the presence of explosives and other contraband through the use of pulsed fast neutron and thermal neutron technologies, as opposed to ionizing radiation. Pulsed fast neutron and thermal neutron technologies permit the operator to inspect cargo, vehicles and containers based on the distinctive chemical composition of explosives, drugs or other contraband.

Our Security division is the only competitor in the market offering x-ray, gamma-ray and neutron-based material specific technologies. As a result, we believe that we offer the broadest technology platform in the cargo and vehicle inspection systems industry. This broad platform also permits us to offer customers hybrid solutions utilizing two or more of the technologies together, thereby optimizing flexibility, performance and cost to meet the customer’s unique application requirements. Cargo and vehicle inspection systems recently installed or currently underway include system installations in the United States, Europe, Western Asia, North Africa and the Middle East, among others.

Our Security division also offers people screening products such as a line of “Metor” brand walk-through metal detection products for use at security checkpoints at airports, amusement parks, banks, courthouses, government buildings, sports arenas and other venues and the Rapiscan Secure 1000 personnel screener, which uses extremely low dose backscatter x-ray imaging to detect contraband and weapons concealed underneath clothing and hair. The Rapiscan Secure 1000 provides enhanced screening compared to metal detectors as it displays anomalies caused by very small amounts of metal as well as non-metallic items. As a result, the Rapiscan Secure 1000 can simultaneously locate and detect conventional metal weapons, as well as ceramic knives, explosives, illicit drugs, precious metals, cameras, recording devices and other contraband or security threats.

The following table sets forth certain information related to the standard security and inspection products that we currently offer. We do, however, also customize our standard products to suit specific applications and customer requirements.

Patient Monitoring, Diagnostic Cardiology and Anesthesia Systems. Our Healthcare businesses design, manufacture and market their products worldwide to end users primarily under the “Spacelabs” trade name.

Spacelabs products include “Ultraview SL” patient monitors, which are used primarily in perioperative, critical care and emergency care environments. We also offer patient monitors for virtually all applications in the hospital, including neonatal, pediatric and adult critical and emergency care, as well as anesthesia and sub-acute care. Our patient monitoring systems comprise monitors and central nursing stations connected via hardwired or wireless networks, as well as stand-alone monitors where the patient data can be transported physically from one monitor to another as the patient is moved. This ensures that hospital staff can access patient data where and when it is required. In addition, these products are designed with an “open architecture” to interact with hospital information systems. WinDNA, based on Citrix thin client technology, is a feature of many of these products which allows clinicians to view and control Microsoft Windows applications on the patient monitor’s display, eliminating the need for separate terminals in the patient’s room. Attending nurses can thereby check laboratory results and other reports, enter orders, review protocols and do charting right at the patient’s bedside. Inputs can be made using a mouse, keyboard and touchscreen.

For electrocardiograph monitoring or multiparameter monitoring of ambulatory patients, we offer a digital telemetry system. The system operates in government-protected bands (608 and 614 MHz and 1.4GHz), not used for private land mobile radio, business radio services or broadcast analog and digital television. The Spacelabs “Ultraview” Digital Telemetry solution comprises a lightweight and compact transmitter that enables monitoring of heart rate, ST segment, arrhythmia and continuous SpO2 (pulse oximetry) monitoring. The multiparameter transmitter also integrates with the Spacelabs “Ultralite” ambulatory blood pressure monitor for the transmission of non-invasive blood pressure values to a central station or a multi-disclosure and information system.

In March 2008, we launched a neonatal monitoring suite, a portfolio of neonatal monitors with specialized designs and colors for the unique needs of the neonatal environment. In May 2008, we introduced the Intesys Clinical Suite G2, an integrated application suite that makes patient data from any networked monitor accessible to any networked computer. It creates a consolidated patient record featuring a series of integrated and synchronized views that permit the clinician to select and focus upon precisely the information needed to understand a critical event. This past year, we also launched the Varitrend 4, which includes significant enhancements, to our Varitrend 3 oxycardiorespirogram display that supports automatic trending and documentation of critical physiological events, such as apnea and bradycardia.

Most recently, in August 2008, we introduced the élance Vital Signs Monitoring product line, an ultra-slim, ultra-lightweight wide-screen monitor. It offers electrocardiograph, respiration, SpO2 (pulse oximetry), non-invasive and invasive blood pressure and temperature monitoring, and end-tidal CO2 (carbon dioxide) monitoring along with an easy-to-use touchscreen interface. The élance is primarily marketed for use in low- to mid-acuity care environments where simplicity and portability are important.

We are also a world leader in ambulatory blood pressure monitoring, which is a routine procedure in many European countries and is increasingly being used in the United States. Many physicians are using ambulatory blood pressure monitoring to detect “white coat” hypertension, a condition in which people experience elevated blood pressure in the doctor’s office, but not in their daily lives. Ambulatory blood pressure monitoring is also used to adjust drug therapies for hypertensive patients. It is estimated that as many as 20% of the patients that are diagnosed with hypertension based on blood pressure measurements taken in their physicians’ offices are not actually hypertensive. Ambulatory blood pressure monitoring helps improve diagnostic accuracy and minimize the associated costs of treatment.

In July 2006, our Healthcare division completed the acquisition of the Del Mar Reynolds cardiology division of Ferraris Group PLC, in significant part to augment the division’s diagnostic cardiology product offerings. Del Mar Reynolds has been developing cardiac monitoring systems, including Holter systems and recorders, for over 40 years. Its “Pathfinder” and “Impresario” lines of Holter analyzers offer users interactive

control with advanced diagnostic parameters. Its “Lifecard” and “Aria” recorders are worn by patients for up to seven days in order to capture heart arrhythmias that may occur in a patient only a few times per week. Patients that may be experiencing even less frequent heart arrhythmias wear its “CardioCall” product, which stays with the patient over several weeks and transmits its findings over the phone to a receiving station in the hospital. In addition to these products, we now offer other diagnostic cardiology products such as the “CD12” electrocardiogram series and “CH2000” stress test systems.

Our anesthesia delivery and ventilation group designs and manufactures anesthesia delivery systems, anesthesia vaporizers and ventilators. Our “Focus,” “Genius” and recently-launched “BleaseSirius” anesthesia delivery systems provide flexible anesthesia solutions for most operating room environments, anesthesia induction areas, day surgery units, magnetic resonance imaging facilities and other areas where the administration of anesthesia is required. Our “Datum” anesthesia vaporizers and line of anesthesia ventilators are also designed to be compatible with the anesthesia delivery systems of several other manufacturers. At the forefront in anesthesia ventilation, this group recognized the needs of clinicians and the clinical benefits of allowing patients to breathe without the assistance of a ventilator (i.e., on their own) as much as possible while undergoing anesthesia. As a result, in 1999, this group became the first to offer ventilators that allowed patients to breathe spontaneously while under anesthesia with the respiratory support of the ventilator used only when necessary to overcome the effects of general anesthesia. In addition, by incorporating spirometry loops into its ventilators, which produce graphical displays reflecting the adequacy and state of a patient’s ventilation, the group was able to provide clinicians with the ability to carefully monitor patients and ensure the efficacy of the mode of ventilation provided.

In fiscal 2007, we added seven new ventilators to our existing product line, each of which enables clinicians to enhance control over the delivery of ventilation and more finely tune their requirements to a surgical procedure and the individual characteristics of a patient by actively controlling flow into and out of the ventilation drive system, throughout the entire respiratory cycle. In addition, each of these new ventilators works in conjunction with a large 8.4 inch touchscreen display. This screen, in conjunction with our proprietary “Touch and Trak” user interface, is easy to use, allowing clinicians to focus greater attention on other aspects of patient care. In fiscal 2007, we launched the BleaseSirius anesthesia delivery systems along with these new ventilators in the United States.

Optoelectronic Devices and Manufacturing Services. Optoelectronic devices generally consist of both active and passive components. Active components sense light of varying wavelengths and convert the light detected into electronic signals, whereas passive components amplify, separate or reflect light. The active components we manufacture consist of silicon, gallium arsenide and indium gallium arsenide photodetectors. Passive components include lenses, prisms, filters, mirrors and other precision optical products that are used by us in the manufacture of our optoelectronic products or are sold to others for use in telescopes, laser printers, copiers, microscopes and other detection and vision equipment. The devices we manufacture are both standard products and products customized for specific applications and are offered either as components or as subsystems.

We have developed two-dimensional back-illuminated detector technology for security, healthcare and industrial CT applications. This technology overcomes the limitations of conventional detectors by providing finer detector pitch density. This is used in high-resolution multi-slice CT scanners and other applications requiring improved image resolution.

In addition to the manufacture of standard and original equipment manufacturer products, we also specialize in designing and manufacturing customized value-added subsystems for use in a wide range of products and equipment. An optoelectronic subsystem typically consists of one or more optoelectronic devices that are combined with other electronic components and packaging for use in an end product. The composition of a subsystem can range from a simple assembly of various optoelectronic devices that are incorporated into other subsystems (for example, a printed circuit board containing our optoelectronic devices) to complete end-products (for example, pulse oximetry equipment). Furthermore, we have expanded our electronics design and manufacturing capabilities both in the United States and in Asia with enhanced, RoHS-compliant, box-build manufacturing services and PC board assembly capabilities utilizing state-of-the-art automated surface mount technology lines. As a result, we now offer electronics manufacturing services for data and signal processing, amplifier and processor boards for medical equipment, musical tuning and studio hardware, motor controls, power supplies, and several other industrial applications that do not utilize optoelectronic devices.

Markets, Customers and Applications

Security and Inspection Products. Most security and inspection products were developed in response to civilian airline hijackings. Consequently, a significant portion of our security and inspection products have been and continue to be sold for use at airports. Recently, however, our security and inspection products have been used for security purposes at locations in addition to airports, such as courthouses, office buildings, mailrooms, schools, prisons, high-profile locations such as Buckingham Palace, the Kremlin and the Vatican and for high-profile events such as the Olympic Games. Furthermore, as terrorist attacks such as the March 2004 bombings of passenger trains at Atocha railway station in Madrid and the July 2005 bombings of the London underground and commuter bus systems occur, overall transportation and travel industry demands have increased, resulting in heightened attention for our security and inspection products. In addition, our security and inspection products are increasingly being used for non-security purposes, such as for cargo inspection to detect narcotics and contraband and to verify manifests, prevention of pilferage at semiconductor manufacturing facilities, quality assurance and the detection of gold and currency.

Our customers include, among many others, the U.S. Transportation Security Administration, U.S. Customs and Border Protection, U.S. Department of Defense and Federal Bureau of Prisons, in the United States, as well as Heathrow and Gatwick Airports in the United Kingdom, Chek Lap Kok Airport in Hong Kong, Ben Gurion International Airport in Israel and the Malaysian Airport Board in Malaysia.

Patient Monitoring, Diagnostic Cardiology and Anesthesia Systems. Our patient monitoring, diagnostic cardiology and anesthesia systems are manufactured and distributed globally for use in critical care, emergency and perioperative areas within hospitals as well as physicians offices, medical clinics and ambulatory surgery centers. We also provide wired and wireless networks and clinical information access solutions, ambulatory blood pressure monitors and medical data services.

We have sold these products to organizations such as Eisenhower Medical Center in Rancho Mirage, California, Cape Fear Valley Health Systems in Fayetteville, North Carolina, Spartanburg Regional Medical Center in Spartanburg, South Carolina, Schüchtermannklinik in Germany, LKW Villach in Austria and Universitätsspital Zürich in Switzerland, among many other organizations, including Premier, Inc., a hospital and healthcare system alliance with approximately 1,500 affiliated hospitals and other healthcare sites.

Optoelectronic Devices and Electronics Manufacturing Services. Our optoelectronic devices and value-added subsystems are used in a broad range of products by a variety of customers. For example, they are utilized by customers in the following market segments: aerospace and avionics; analytical and medical imaging; fiber optics and telecommunications; gaming; homeland security; healthcare; military and weapons simulation; office automation; and toll and traffic management. Major customers in these segments include: Honeywell, Raytheon, JDS Uniphase, ITT Corp., Bally Technologies, Gilardoni, Heidenhain, Smiths Medical, Somanetics, Lockheed Martin, Xerox and Florida Department of Transportation, among others.

Marketing, Sales and Service

We market and sell our security and inspection products worldwide through a direct sales and marketing staff of approximately 71 employees located in North America, Europe, Asia and Australia, in addition to an expansive global network of independent and specialized sales representatives. This sales staff is supported by a service organization located primarily in North America, Europe and Asia, as well as a global network of independent distributors. We also support these sales and customer relations efforts by providing operator training, computerized training and testing equipment, in-country service support, software upgrades and service training for customer technicians.

We market and sell our patient monitoring, diagnostic cardiology and anesthesia systems worldwide through a direct sales and marketing staff of approximately 276 sales personnel and 245 service personnel located in North America, Europe and Asia, in addition to a global network of independent distributors. We also support these sales and customer service efforts by providing operator in-service training, software updates and upgrades and service training for customer biomedical staff and distributors.

We market and sell our optoelectronic devices and value-added manufacturing services, through both a direct sales and marketing staff of approximately 33 employees located in North America, Europe and Asia, and indirectly through a global network of independent sales representatives and distributors. We also maintain a worldwide network of independent sales representatives and distributors. Our sales staff is supported by an applications engineering group whose members are available to provide technical support, which includes designing applications, providing custom tooling and process integration and developing products that meet customer defined specifications.

We consider our maintenance service operations to be an important element of our business. After the expiration of our standard product warranty periods, we are sometimes engaged by our customers to provide maintenance services for our security and inspection products through annual maintenance contracts. We provide a variety of service and support options for our patient monitoring, diagnostic cardiology and anesthesia systems customers, ranging from complete on-site repair and maintenance service and telephone support to parts exchange programs for customers with the internal expertise to perform a portion of their own service needs. We believe that our international maintenance service capabilities allow us to be competitive in selling our security and inspection systems as well as our patient monitoring, diagnostic cardiology and anesthesia systems. Furthermore, we believe that as the installed base of both our security and inspection systems and patient monitoring, diagnostic cardiology and anesthesia systems increases, revenues generated from such annual maintenance service contracts and from the sale of replacement parts will increase.

Research and Development

Our security and inspection systems are primarily designed at our facilities in the United States and internationally in Finland, Malaysia, India and the United Kingdom. These products include mechanical, electrical, analog electronic, digital electronic and software subsystems, which are all designed by us. In addition to product design, we provide system integration services to integrate our products into turnkey systems at the customer site. We support cooperative research projects with government agencies and, on occasion, provide contract research for our customers and government agencies.

Our patient monitoring, diagnostic cardiology and anesthesia systems are primarily designed at our facilities in the United States and internationally in China, India and the United Kingdom. Such systems include mechanical, electrical, digital electronic and software subsystems, all of which are designed by us. We are also currently involved, both in the United States and internationally, in several research projects aimed at improving our medical systems and at expanding our current product line.

Our optoelectronic devices and value-added subsystems are primarily designed and engineered at our facilities in the United States and internationally in India, Malaysia, Norway and Singapore. We engineer and manufacture subsystems to solve the specific application needs of our original equipment manufacturer customers. In addition, we offer entire subsystem design and manufacturing solutions. We consider our engineering personnel to be an important extension of our core sales and marketing efforts.

In addition to close collaboration with our customers in the design and development of our current products, we maintain an active program for the development and introduction of new products, enhancements and improvements to our existing products, including the implementation of new applications of our technology. We seek to further enhance our research and development program and consider such program to be an important element of our business and operations. As of June 30, 2008, we engaged approximately 366 full-time engineers, technicians and support staff. Our research and development expenses were $35.9 million in fiscal 2006, $44.4 million in fiscal 2007 and $45.3 million in fiscal 2008. We intend to continue to invest in our research and development efforts in the future.

Manufacturing and Materials

We currently manufacture our security and inspection systems domestically in California, Mississippi and North Carolina, and internationally in Finland, Malaysia and the United Kingdom. We currently manufacture our patient monitoring, diagnostic cardiology and anesthesia systems domestically in Washington, and internationally in China and the United Kingdom. We currently manufacture our optoelectronic devices and value-added subsystems domestically in California, Massachusetts and Mississippi, and internationally in India, Indonesia, Malaysia, Singapore and Norway. Most of our high volume, labor intensive manufacturing and assembly is performed at our facilities in Indonesia and Malaysia. Since most of our customers are located in the United States, Europe and Asia, our ability to assemble products in these markets and provide follow-on service from offices located in these regions is an important component of our global strategy.

Our global manufacturing organization has expertise in optoelectronic, microelectronic and integrated value-added assemblies for commercial, medical, aerospace and defense industry applications. Our manufacturing includes silicon wafer processing and fabrication, optoelectronic device assembly and screening, thin and thick film microelectronic hybrid assemblies, surface mounted and thru-hole printed circuit board electronic assemblies and value-added services, including complete turn-key and box-build manufacturing. We outsource certain manufacturing operations, including certain sheet metal fabrication and plastic components. The manufacturing process for components and subsystems consists of manual tasks performed by skilled technicians as well as automated tasks.

The principal raw materials and subcomponents used in producing our security and inspection systems consist primarily of x-ray generators, linear accelerators, radioactive isotopes, neutron generators, detectors, data

acquisition and computer systems, and conveyance systems. A large portion of the optoelectronic devices, subsystems and circuit card assemblies used in our inspection and detection systems are manufactured in-house. The metal enclosures used in our baggage and parcel inspection systems are also manufactured in-house, while the x-ray generators, linear accelerators, radioactive isotopes, neutron generators and conveyance systems used in our cargo and vehicle inspection systems are purchased from unaffiliated third party providers.

The principal raw materials and subcomponents used in producing our patient monitoring, diagnostic cardiology and anesthesia systems consist of printed circuit boards, housings, mechanical assemblies, pneumatic devices, cables, filters and packaging materials. We purchase certain devices, including computers, peripheral accessories and remote displays from unaffiliated third party providers.

The principal raw materials and subcomponents used in producing our optoelectronic devices and value-added subsystems consist of silicon wafers, electronic components, light emitting diodes, scintillation crystals, passive optical components, printed circuit boards, and packaging materials. The silicon-based optoelectronic devices manufactured by us are critical components in most of our products and subsystems. We purchase silicon wafers and other electronic components from unaffiliated third party providers.

For cost, quality control and efficiency reasons, at times we purchase raw materials and subcomponents only from single vendors with whom we have ongoing relationships. We do, however, qualify second sources for most of our raw materials and critical components, or have identified alternate sources of supply. We purchase the materials pursuant to purchase orders placed from time to time in the ordinary course of business. Although to date none of our divisions has experienced any significant shortages or material delays in obtaining any of its raw materials or subcomponents, it is possible that they may face such shortages or delays in one or more materials in the future.

Patents, Trademarks, Tradenames and Licenses

Trademarks and Tradenames. We have used, registered and applied to register certain trademarks and service marks to distinguish our products, technologies and services from those of our competitors in the United States and in foreign countries. We enforce our trademark, service mark and trade name rights in the United States and abroad.

Patents. We hold a number of U.S. and foreign patents relating to various aspects of our security and inspection products, patient monitoring, diagnostic cardiology and anesthesia systems and optoelectronic devices and subsystems. Our current patents will expire at various times between 2008 and 2026. However, it remains possible that pending patent applications or other applications that may be filed may not result in issued patents. In addition, issued patents may not survive challenges to their validity. Although we believe that our patents have value, our patents, or any additional patents that may be issued in the future, may not be able to provide meaningful protection from competition.

Licenses. Our Security, Healthcare and Optoelectronics and Manufacturing divisions have each entered into a variety of license arrangements under which they are permitted to manufacture, market, sell and/or service various types of software, data, equipment, components and enhancements to our own proprietary technology.

We believe that our trademarks and tradenames, patents and licenses are important to our business. The loss of some of our trademarks, patents or licenses might have a negative impact on our financial results and operations. However, we operate in a competitive environment with a known customer base and rely mainly on providing our customers with quality products and services to ensure continuing business. Thus, with the exception of the loss of either the Spacelabs^® or Rapiscan^® trademarks, the impact of the loss of any single trademark, patent or license would not likely have a material adverse effect on our business. We consider the Spacelabs^® trademark an important asset and have registered it in approximately forty countries. In addition, following the re-branding of our Security division under the “Rapiscan Systems” name, we have instituted a similar registration program for the Rapiscan^® trademark.

Regulation of Medical Products

The patient monitoring, diagnostic cardiology and anesthesia systems we manufacture and market are subject to regulation by numerous government agencies, principally the U.S. Food and Drug Administration (FDA) and by certain state and foreign authorities. They are also subject to various U.S. and foreign electrical safety standards.

The FDA has broad regulatory powers with respect to pre-clinical and clinical testing of new medical products and the designing, manufacturing, marketing and advertising of medical products. It requires that all medical devices introduced into the market be preceded either by a pre-market notification clearance order under section 510(k) of the Food, Drug and Cosmetic Act, or an approved pre-market approval application. A 510(k) pre-market notification clearance order indicates that the FDA agrees with an applicant’s determination that the product for which clearance has been sought is substantially equivalent to another legally marketed medical device. The clearance of a pre-market approval application, on the other hand, indicates that the FDA has determined that the device has been proven, through the submission of clinical trial data and manufacturing quality assurance information, to be safe and effective for its labeled indications. The process of obtaining 510(k) clearance typically takes between three and six months, but can take substantially longer. The pre-market approval application review process, on the other hand, can last more than a year. To date, all of the patient monitoring, diagnostic cardiology and anesthesia systems we manufacture and sell in the United States have required only 510(k) pre-market notification clearance.

Such regulatory approvals, when granted, may entail limitations on the indicated uses for which a product may be marketed, and such product approvals, once granted, may be withdrawn if problems occur after initial marketing. Manufacturers of FDA-regulated products are subject to pervasive and continuing governmental regulation, including extensive recordkeeping requirements and reporting of adverse experiences associated with product manufacture and use. Compliance with these requirements is costly, and failure to comply can result in, among other things, fines, total or partial suspension of production, product recalls, failure of the FDA to review pending marketing clearances or approval applications, withdrawal of marketing clearances or approvals or even criminal prosecution.

We are also subject to regulation in the foreign countries in which we manufacture and market our patient monitoring, diagnostic cardiology and anesthesia systems. For example, the commercialization of medical devices in the European Union is regulated under a system that presently requires all medical devices sold in the European Union to bear the CE mark—an international symbol of adherence to quality assurance standards. Our manufacturing facilities in Hawthorne, California; Issaquah, Washington; Suzhou in China; and in Chesham and Hertford in the United Kingdom are all certified to the International Organization for Standardization’s ISO 13485 standard for medical device companies. They are also certified to the requirements of the European Medical Device Directive 93/42 EEC, which allows them to self-certify that newly manufactured products can bear the CE mark.

We believe we are in compliance with all applicable federal, state and foreign regulations regarding the manufacture and sale of our patient monitoring, diagnostic cardiology and anesthesia delivery systems except to an extent that would not have a material adverse effect on our business, financial condition or results of operations. Such regulations and their enforcement do, however, constantly change, and we cannot predict what effect, if any, such changes may have on our businesses in the future.

Environmental Regulations

We are subject to various federal, state and local environmental laws, ordinances and regulations relating to the use, storage, handling and disposal of certain hazardous substances and wastes used or generated in the manufacturing and assembly of our products. Under such laws, we may become liable for the costs of removal or remediation of certain hazardous substances that have been released on or in our facilities or that have been disposed of off-site as waste. Such laws may impose liability without regard to whether we knew of, or caused,

the release of such hazardous substances. We have conducted Phase I environmental site assessments for each of our properties in the United States at which we manufacture products. The purpose of each such report is to identify, as of the date of such report, potential areas of environmental concern related to past and present activities or from nearby operations. In certain cases, we have conducted further environmental assessments consisting of soil and groundwater testing and other investigations deemed appropriate by independent environmental consultants. We believe that, except to an extent that would not have a material adverse effect on our business, financial condition or results of operations, we are currently in compliance with all environmental regulations in connection with our manufacturing operations, and that we have obtained all environmental permits necessary to conduct our business. The amount of hazardous substances and wastes produced and generated by us may increase in the future depending on changes in our operations. Any failure by us to comply with present or future regulations could subject us to the imposition of substantial fines, suspension of production, alteration of manufacturing process or cessation of operations, any of which could have a material adverse effect on our business, financial condition and results of operations.

During one investigation, we discovered soil and groundwater contamination at our Hawthorne, California facility. We filed the requisite reports concerning this problem with the appropriate environmental authorities in fiscal 2001. We have not yet received any response to such reports, and no agency action or litigation is presently pending or threatened. We also have notified the prior owners of the facility and the present owners and tenants of adjacent properties concerning the problem and have requested from such parties agreements to toll of the statute of limitations with respect to actions against such parties with respect to the contamination in order that we may focus our attention on resolution of the contamination problem. Our site was previously used by other companies for semiconductor manufacturing similar to that presently conducted on the site by us, and it is not presently known who is responsible for the contamination or, if required, the remediation. The groundwater contamination is a known regional problem, not limited to our premises or our immediate surroundings.

We have also been informed of soil and groundwater evaluation efforts at a facility that our Ferson Technologies subsidiary previously leased in Ocean Springs, Mississippi. Ferson Technologies occupied the facility between 1993 and 2003. We believe that the owner and previous occupants of the facility have primary responsibility for any remediation that may be required and have an agreement with the facility’s owner under which the owner is responsible for remediation of pre-existing conditions. However, as site evaluation efforts are still in progress, and may be for some time, we are unable at this time to ascertain whether Ferson Technologies bears any exposure for remediation costs under applicable environmental regulations.

Competition

The markets in which we operate are highly competitive and characterized by evolving customer needs and rapid technological change. We compete with a number of other manufacturers, some of which have significantly greater financial, technical and marketing resources than we have. In addition, these competitors may have the ability to respond more quickly to new or emerging technologies, adapt more quickly to changes in customer requirements, have stronger customer relationships, have greater name recognition and may devote greater resources to the development, promotion and sale of their products than we do. As a result, we may not be able to compete successfully against designers and manufacturers of specialized electronic systems and components, broadly speaking, or more specifically within the markets for security and inspection systems, patient monitoring, diagnostic cardiology and anesthesia systems, or optoelectronic devices. Future competitive pressures may materially and adversely affect our business, financial conditions and results of operations.

In the security and inspection market, competition is based primarily on such factors as product performance, functionality and quality, the overall cost effectiveness of the system, prior customer relationships, technological capabilities of the products, price, local market presence and breadth of sales and service organization. We believe that our principal competitors in the market for security and inspection products are Smiths Detection; L-3 Communications—Security and Detection Systems; American Science and Engineering; GE Security; SAIC; CEIA; Garrett Electronics and Nuctech. Competition could result in price reductions,

reduced margins and loss of market share. In the airline and airport security and inspection market, particularly in the upgrade and replacement market, we also compete for potential customers based on existing relationships between our competitors and the customers. Certain of our competitors have established strong relationships with airlines, airports and other transportation security authorities. Although we also have established relationships with a number of airport and airline customers, we may not be able to compete successfully in the future with existing competitors or new entrants. In the cargo and vehicle inspection systems market, we compete for potential customers based on price, performance and the ability to design both standard and customized products. Several of our competitors have operated in this area for longer than we have. However, due to our recent successes in designing and delivering high-energy x-ray and gamma-ray systems, we believe that we have demonstrated an ability to compete effectively. Additionally, although our competitors in the cargo and vehicle inspection market each offer products in competition with one or more of our products, our ability to supply high-energy x-ray and gamma-ray systems means that we offer among the widest array of solutions available from a single supplier. This variety of technologies also permits us to offer unique hybrid systems to our customers that utilize two or more of these technologies, thereby optimizing flexibility, performance and cost to meet the customer’s unique application requirements.

In the patient monitoring, diagnostic cardiology and anesthesia systems delivery market, competition is also based on a variety of factors including product performance, functionality, value and breadth of sales and service organization. We believe that our principal competitors in the market for patient monitoring, diagnostic cardiology and anesthesia systems are Philips Medical; GE Healthcare; Mindray Medical, Cardiac Science; Mortara Instrument; Dräger Medical; Nihon Kohden; Penlon and Nellcor. Competition could result in price reductions, reduced margins and loss of our market share. We believe that our patient monitoring products are easier to use than the products of many of our competitors because we offer a consistent user interface throughout many of our product lines. Finally, while some of our competitors are also beginning to introduce portal technology, which allows remote access to data from the bedside monitor, central station or other point of care, we believe that our competing technologies are superior in bringing instant access to labs, radiology and charting at the point of care. Although we have established relationships with a number of large hospitals, we may not be able to successfully compete in the future with existing competitors or with new entrants.

In the optoelectronic devices and subsystems market, competition for optoelectronic devices and value-added subsystems is based primarily on such factors as expertise in the design and development of optoelectronic devices, product quality, timeliness of delivery, price, customer technical support and on the ability to provide fully integrated services from application development and design through production. We believe that our major competitors in the optoelectronic device market are PerkinElmer and Hamamatsu. Because we specialize in custom subsystems requiring a high degree of engineering expertise, we believe that we generally do not compete to any significant degree with any other large United States, European or Asian manufacturers of standard optoelectronic components. Competition in the extensive electronic manufacturing services market ranges from multinational corporations with sales in excess of several billions of dollars, to large regional competitors and to small local assembly companies. In our experience, the original equipment manufacturers to whom we provide such services prefer to engage companies that offer both local and lower-cost off-shore facilities. As a result, our primary domestic competition for these services is located in Southern California and in New England, where our U.S. facilities are also located. Such competition includes CTS; Stellar Manufacturing; Senior Systems Technology; Celestica and Benchmark Electronics, among others. In addition, our high-volume, low-cost contract manufacturing locations in Southeast Asia compete with other manufacturers in the same region.

Backlog

We measure our backlog as orders for which purchase orders or contracts have been signed, but which have not yet been shipped and for which revenues have not yet been recognized.

We ship most of our baggage and parcel inspection, hold (checked) baggage screening, people screening, patient monitoring, diagnostic cardiology and anesthesia systems and optoelectronic devices and value-added

subsystems within one to several months after receiving an order. However, such shipments may be delayed for a variety of reasons, including any special design or engineering requirements of the customer. In addition, large orders of security and inspection products (more than ten machines) typically require greater lead-times.

Certain of our cargo and vehicle inspection and hold (checked) baggage screening systems may require several months to several years lead-time. We have experienced some significant shipping delays associated with our cargo and vehicle inspection systems. Such delays can occur for many reasons, including: (i) additional time necessary to conduct inspections at the factory before shipment; (ii) a customer’s need to engage in time-consuming special site preparation to accommodate the system, over which we have no control or responsibility; (iii) additional fine tuning of such systems once they are installed; (iv) design or specification changes by the customer; and (v) delays originating from other contractors on the project.

As of June 30, 2008, our consolidated backlog totaled approximately $212 million, compared to approximately $209 million as of June 30, 2007 and approximately $147 million at June 30, 2006. Sales orders underlying our backlog are firm orders. However, from time to time, we may agree to permit the cancellation of an order. Variations in the size of orders, product mix, or delivery requirements, among other factors, may result in substantial fluctuations in backlog from period to period. Backlog as of any particular date should not be relied upon as indicative of our revenues for any future period and cannot be considered a meaningful indicator of our performance on an annual or quarterly basis.

Employees

As of June 30, 2008, we employed approximately 3,366 people, of whom 1,826 were employed in manufacturing, 366 were employed in engineering or research and development, 384 were employed in administration, 380 were employed in sales and marketing and 410 were employed in service capacities. Of the total employees, approximately 1,462 were employed in North America and South America, 1,406 were employed in Asia and 498 were employed in Europe. Many of our employees in Europe have statutory collective bargaining rights. We have never experienced a work stoppage or strike, and management believes that its relations with employees are good.

ITEM 1A.

RISK FACTORS

Fluctuations in our operating results may cause our stock price to decline.

Given the nature of the markets in which we participate, we cannot always reliably predict future revenues and profitability. Changes in competitive, market and economic conditions may cause us to adjust our operations.

A high proportion of our costs are fixed, due in part to our significant sales, research and development and manufacturing costs. Thus, small declines in revenue could disproportionately affect our operating results. Factors that may affect our operating results and the market price of our Common Stock include:

•

demand for and market acceptance of our products;

•

competitive pressures resulting in lower selling prices;

•

adverse changes in the level of economic activity in regions in which we do business;

•

low or fluctuating levels of political stability in regions in which we do business;

•

adverse changes in industries, such as semiconductors and electronics, on which we are particularly dependent;

•

changes in the portions of our revenue represented by various products and customers;

•

delays or problems in the introduction of new products;

•

the announcement or introduction of new products, services or technological innovations by our competitors;

•

variations in our product mix;

•

the timing and amount of our expenditures in anticipation of future sales;

•

exchange rate fluctuations;

•

increased costs of raw materials or supplies;

•

changes in the volume or timing of product orders;

•

timing of completion of acceptance testing of some of our products;

•

changes in regulatory requirements;

•

natural disasters; and

•

changes in general economic factors.

We face aggressive competition in many areas of business. If we do not compete effectively, our business will be harmed.

We encounter aggressive competition from numerous competitors in many areas of our business. In the security and inspection and patient monitoring, diagnostic cardiology and anesthesia systems markets, competition is based primarily on such factors as product performance, functionality and quality, cost, prior customer relationships, technological capabilities of the product, price, certification by government authorities, local market presence and breadth of sales and service organization. In the optoelectronic devices and electronics manufacturing markets competition is based primarily on factors such as expertise in the design and development of optoelectronic devices, product quality, timeliness of delivery, price, customer technical support and on the ability to provide fully-integrated services from application development and design through volume subsystem production. We may not be able to compete effectively with all of our competitors. To remain competitive, we must develop new products and enhance our existing products and services in a timely manner. We anticipate that we may have to adjust prices of many of our products to stay competitive. In addition, new competitors may emerge, and entire product lines or service offerings may be threatened by new technologies or market trends that reduce the value of these product lines or service offerings.

The September 11, 2001 terrorist attacks and the creation of the U.S. Department of Homeland Security have increased financial expectations that may not materialize.

The September 11, 2001 terrorist attacks and the subsequent creation of the U.S. Department of Homeland Security have created increased interest in our security and inspection systems. However, we are not certain whether the level of demand will continue to be as high as it is now. We do not know what solutions will

continue to be adopted by the U.S. Department of Homeland Security, the U.S. Department of Defense, and similar agencies in other countries and whether our products will be a part of those solutions. Additionally, should our products be considered as a part of the future security solutions, it is unclear what the level may be and how quickly funding to purchase our products may be made available. These factors may adversely impact us and create unpredictability in revenues and operating results.

If operators of our security and inspection systems fail to detect weapons, explosives or other devices that are used to commit a terrorist act, we could be exposed to product liability and related claims for which we may not have adequate insurance coverage.

Our business exposes us to potential product liability risks that are inherent in the development, manufacturing, sale and service of security inspection systems as well as in the provision of training to our customers in the use and operation of such systems. Our customers use our security and inspection systems to help them detect items that could be used in performing terrorist acts or other crimes. Some of our security and inspection systems require that an operator interpret an image of suspicious items within a bag, parcel, container or other vessel. Others signal to the operator that further investigation is required. In either case, the training, reliability and competence of the customer’s operator are crucial to the detection of suspicious items.

Security inspection systems that signal to the operator that further investigation is required are sometimes referred to in the security industry as “automatic” detection systems. Such systems utilize software algorithms to interpret data produced by the system and to signal to the operator when a dangerous object may be present. Such algorithms are probabilistic in nature and are also subject to significant technical limitations. Nevertheless, if such a system were to fail to signal to an operator when an explosive or other contraband was in fact present, resulting in significant damage, we could become the subject of significant product liability claims.

Furthermore, security inspection by technological means is always circumstance and application-specific. In addition, our security and inspection systems are not designed to work under all circumstances. We test the reliability of our security and inspection systems during both their development and manufacturing phases. We also perform such tests if we are requested to perform installation, warranty or post-warranty servicing. However, our security inspection systems are advanced mechanical and electronic devices and therefore can malfunction. In addition, there are also many other factors beyond our control that could lead to liability claims should an act of terrorism occur. The September 11, 2001 and 1993 World Trade Center bombing attacks, and the potential for future attacks, have caused commercial insurance for such threats to become extremely difficult to obtain. It is very likely that, should we be found liable following a major act of terrorism, the insurance we currently have in place would not fully cover the claims for damages.

Our patient monitoring, diagnostic cardiology and anesthesia systems could give rise to product liability claims that could materially and adversely affect our financial condition and results of operations.

The development, manufacturing and sale of medical devices expose us to significant risk of product liability claims and, sometimes, product failure claims. We face an inherent business risk of financial exposure to product liability claims if the use of our medical devices results in personal injury or death. Substantial product liability litigation currently exists within the medical device industry. Some of our patient monitoring, diagnostic cardiology and anesthesia systems businesses are, from time to time, subject to product liability claims and/or product recalls. Future product liability claims may exceed the limits of our insurance coverages or such insurance may not continue to be available to us on commercially reasonable terms, or at all. Consequently, a product liability claim or other claim with respect to uninsured liabilities, or in excess of insured liabilities, could have a material adverse effect on our business, financial condition, operating results and cash flows.

If we are unable to sustain high quality processes for the manufacture and delivery of goods and services, our reputation could be harmed, our competitive advantage could erode and we could incur significant costs.

Quality is extremely important to us and our customers due in part to the serious consequences of product failure. Our quality certifications are critical both to the marketing success of our goods and services and to the satisfaction of both regulatory and contractual requirements under which we sell many of our products. If we fail to meet these standards or other standards required in our industries, we could lose customers and market share, our revenue could decline and we could face significant costs and other liabilities.

Our revenues are dependent on orders of security and inspection systems and patient monitoring, diagnostic cardiology and anesthesia systems, which may have lengthy and unpredictable sales cycles.

Sales of security and inspection systems often depend upon the decision of governmental agencies to upgrade or expand existing airports, border crossing inspection sites, seaport inspection sites and other security installations. Sales outside of the United States of our patient monitoring, diagnostic cardiology and anesthesia systems depend in significant part on the decision of governmental agencies to build new medical facilities or to expand or update existing medical facilities. Accordingly, a significant portion of our sales of security and inspection systems and our patient monitoring, diagnostic cardiology and anesthesia systems is often subject to delays associated with the lengthy approval processes that typically accompany such capital expenditures. During these approval periods, we expend significant financial and management resources in anticipation of future orders that may not occur. If we fail to receive an order after expending such resources, such failure could have a material adverse effect on our business, financial condition and results of operations.

If we do not introduce new products in a timely manner, our products could become obsolete and our operating results would suffer.

We sell many of our products in industries characterized by rapid technological changes, frequent new product and service introductions and evolving industry standards and customer needs. Without the timely introduction of new products and enhancements, our products could become technologically obsolete over time, in which case our revenue and operating results would suffer. The success of our new product offerings will depend upon several factors, including our ability to:

•

accurately anticipate customer needs;

•

innovate and develop new technologies and applications;

•

successfully commercialize new technologies in a timely manner;

•

price our products competitively and manufacture and deliver our products in sufficient volumes and on time; and

•

differentiate our offerings from our competitors’ offerings.

Some of our products are used by our customers to develop, test and manufacture their products. We therefore must anticipate industry trends and develop products in advance of the commercialization of our customers’ products. In developing any new product, we may be required to make a substantial investment before we can determine the commercial viability of the new product. If we fail to accurately foresee our customers’ needs and future activities, we may invest heavily in research and development of products that do not lead to significant revenues.

Interruptions in our ability to purchase raw materials and components may adversely affect our profitability.

We purchase certain raw materials and subcomponents from third parties pursuant to purchase orders placed from time to time. Standard purchase order terms are as long as one year at fixed costs, but we do not have

guaranteed long-term supply arrangements with our suppliers. Any material interruption in our ability to purchase necessary raw materials or subcomponents could have a material adverse effect on our business, financial condition and results of operations.

We may not be able to successfully implement our acquisitions strategy, integrate acquired businesses into our existing business or make acquired businesses profitable.

One of our strategies is to supplement our internal growth by acquiring businesses and technologies that complement or augment our existing product lines. This growth has placed, and may continue to place, significant demands on our management, working capital and financial resources. We may be unable to identify or complete promising acquisitions for many reasons, including:

•

competition among buyers;

•

the need for regulatory approvals, including antitrust approvals; and

•

the high valuations of businesses.

Some of the businesses we may seek to acquire may be marginally profitable or unprofitable. For these acquired businesses to achieve acceptable levels of profitability, we must improve their management, operations, products and market penetration. We may not be successful in this regard and may encounter other difficulties in integrating acquired businesses into our existing operations.

To finance our acquisitions, we may have to raise additional funds, through either public or private financings. We may be unable to obtain such funds or may be able to do so only on unfavorable terms.

Our acquisition and alliance activities could disrupt our ongoing business.

We intend to continue to make investments in companies, products and technologies, either through acquisitions, investments or alliances. Acquisition and alliance activities often involve risks, including: (i) difficulty in assimilating the acquired operations and employees; (ii) difficulty in managing product co-development activities with our alliance partners; (iii) difficulty in retaining the key employees of the acquired operation; (iv) disruption of our ongoing business; (v) inability to successfully integrate the acquired technologies and operations into our businesses and maintain uniform standards, controls, policies and procedures; and (vi) lacking the experience necessary to enter into new product or technology markets successfully. In addition, from time to time, our competitors acquire or enter into exclusive arrangements with companies with whom we do business or may do business in the future. Reductions in the number of partners with whom we may do business in a particular context may reduce our ability to enter into critical alliances on attractive terms or at all, and the termination of an existing alliance by a business partner may disrupt our operations.

Economic, political and other risks associated with international sales and operations could adversely affect our sales.

In fiscal 2006, revenues from shipments made outside of the United States accounted for approximately 42% of our revenues, 47% in fiscal 2007 and 47% in fiscal 2008. Of the revenues generated during fiscal 2008 from shipments made to customers outside of the United States, 20% represented sales made by subsidiaries based in the United States to foreign customers, and the balance represented sales generated by foreign subsidiaries. Since we sell certain of our products worldwide, our businesses are subject to risks associated with doing business internationally. We anticipate that revenues from international operations will continue to represent a substantial portion of our total revenue. In addition, many of our manufacturing facilities, and therefore employees, suppliers, real property, capital equipment, cash and other assets are located outside the United States. Accordingly, our future results could be harmed by a variety of factors, including:

•

changes in foreign currency exchange rates;

•

changes in a country’s or region’s political or economic conditions, particularly in developing or emerging markets;

•

longer payment cycles of foreign customers and difficulty of collecting receivables in foreign jurisdictions;

•

trade protection measures and import or export licensing requirements;

•

differing legal and court systems;

•

differing tax laws and changes in those laws;

•

difficulty in staffing and managing widespread operations;

•

differing labor laws and changes in those laws;

•

differing protection of intellectual property and changes in that protection; and

•

differing regulatory requirements and changes in those requirements.

Our competitors may seek to challenge the intellectual property rights on which our products are based.

As we introduce any new and potentially promising product, companies possessing competing technologies may be motivated to assert infringement claims in order to delay or diminish potential sales and challenge our right to market such product. In addition, we may find it necessary to initiate litigation in order to protect our patent or other intellectual property rights.

Under either circumstance, we may incur significant expenses. In addition, claims of third parties against us could result in awards of substantial damages or court orders that could effectively prevent us from making, using or selling our products in the United States or abroad.

Our ongoing success is dependent upon the continued availability of certain key employees.

We are dependent in our operations on the continued availability of the services of our employees, many of whom are individually key to our current and future success, and the availability of new employees to implement our growth plans. In particular, we are dependent upon the services of Deepak Chopra, our Chairman of the Board of Directors, President and Chief Executive Officer. The market for skilled employees is highly competitive, especially for employees in technical fields. While our compensation programs are intended to attract and retain the employees required for it to be successful, ultimately, we may not be able to retain the services of all of our key employees or a sufficient number to execute on our plans. In addition, we may not be able to continue to attract new employees as required.

Substantial government regulation in the United States and abroad may restrict our ability to sell our patient monitoring, diagnostic cardiology and anesthesia systems.

The FDA and comparable regulatory authorities in foreign countries extensively and rigorously regulate our patient monitoring, diagnostic cardiology and anesthesia systems, including related development activities and manufacturing processes. In the United States, the FDA regulates the introduction of medical devices as well as the manufacturing, labeling and record-keeping procedures for such products. We are required to:

•

obtain clearance before we can market and sell medical devices;

•

satisfy content requirements applicable to our labeling, sales and promotional materials;

•

comply with manufacturing and reporting requirements; and

•

undergo rigorous inspections.

Our future products may not obtain FDA clearance on a timely basis, or at all. Our patient monitoring, diagnostic cardiology and anesthesia systems must also comply with the laws and regulations of foreign countries in which we develop, manufacture and market such products. In general, the extent and complexity of

medical device regulation is increasing worldwide. This trend is likely to continue and the cost and time required to obtain marketing clearance in any given country may increase as a result. Our products may not obtain any necessary foreign clearances on a timely basis, or at all.

Once any of our patient monitoring, diagnostic cardiology and anesthesia systems is cleared for sale, regulatory authorities may still limit the use of such product, prevent its sale or manufacture or require a recall or withdrawal of such product from the marketplace. Following initial clearance from regulatory authorities, we continue to be subject to extensive regulatory requirements. Government authorities can withdraw marketing clearance due to our failure to comply with regulatory standards or due to the occurrence of unforeseen problems following initial clearance. Ongoing regulatory requirements are wide-ranging and govern, among other things:

•

annual inspections to retain a CE mark for sale of products in the European Union;

•

product manufacturing;

•

supplier substitution;

•

product changes;

•

process modifications;

•

medical device reporting; and

•

product sales and distribution.

Our failure to comply with environmental regulations may create significant environmental liabilities and force us to modify our manufacturing processes.

We are subject to various foreign and U.S. federal, state and local environmental laws, ordinances and regulations relating to the use, storage, handling and disposal of certain hazardous substances and wastes used or generated in the manufacturing and assembly of our products. Under such laws, we may become liable for the costs of removal or remediation of certain hazardous substances or wastes that have been or are being disposed of offsite as wastes or that have been or are being released on or in our facilities. Such laws may impose liability without regard to whether we knew of, or caused, the release of such hazardous substances or wastes. Any failure by us to comply with present or future regulations could subject us to the imposition of substantial fines, suspension of production, alteration of manufacturing processes, or cessation of operations, any of which could have a material adverse effect on our business, financial condition and results of operations.

We may be exposed to potential risks relating to our internal controls over financial reporting and our ability to have our independent registered public accounting firm attest to these controls.

As directed by the Sarbanes-Oxley Act of 2002, the Securities and Exchange Commission adopted rules requiring public companies to include in their annual reports an assessment of the effectiveness of the company’s internal controls over financial reporting. In addition, the independent registered public accounting firm auditing a public company’s financial statements must attest to and report on management’s assessment of the effectiveness of the company’s internal controls over financial reporting, as well as the operating effectiveness of the company’s internal controls over financial reporting. We evaluate our internal controls over financial reporting in order to allow our management to report on, and our independent registered public accounting firm to attest to, our internal controls.

We expect to continue to expend significant resources in complying with the documentation and testing procedures required by the Sarbanes-Oxley Act of 2002. However, there will remain an ongoing risk that we will not comply with all of its requirements.

If our independent registered public accounting firm differs from us in its interpretation of the requirements imposed on us by the Sarbanes-Oxley Act of 2002, or if it is not satisfied with our internal controls over financial reporting or with the level at which such controls are documented, operated or reviewed, we may be delayed in

filing reports with the Securities and Exchange Commission, our independent registered public accounting firm may decline to attest to our management’s assessment or it may issue a qualified report. In addition, if our independent registered public accounting firm is unable to rely on our internal controls over financial reporting in connection with its audit of our financial statements and if it is unable to devise alternative procedures in order to satisfy itself as to the material accuracy of our financial statements and related disclosures, it is possible that we could receive a qualified or adverse audit opinion in connection with those financial statements.

Accordingly, we may not receive a favorable report from our independent registered public accounting firm regarding our internal controls over financial reporting and the operating effectiveness of our internal controls over financial reporting. If we identify material weaknesses in our internal controls over financial reporting that we cannot remediate in a timely manner or if we receive an adverse report from our independent registered public accounting firm with respect to our internal controls over financial reporting, investors and others may lose confidence in the reliability of our financial statements and the market for our Common Stock could be adversely affected.

We receive significant amounts of research and development funding for our security and inspection systems from government grants and contracts, but we may not continue to receive comparable levels of funding in the future.

The U.S. government currently plays an important role in funding the development of certain of our security and inspection systems and sponsoring their deployment at airports, ports and border crossings. However, in the future, additional research and development funds from the government may not be available to us. If the government fails to continue to sponsor our technologies we may have to expend more resources on product development or cease development of certain technologies, which could adversely affect our business. In addition, any future grants to our competitors may improve their ability to develop and market competing products and cause our customers to delay purchase decisions, which could harm our ability to market our products.

Our credit facility contains provisions that could restrict our ability to finance our future operations or engage in other business activities that may be in our interest.

Our credit facility contains a number of significant covenants that, among other things, limit our ability to:

•

dispose of assets;

•

incur certain additional indebtedness;

•

repay certain indebtedness;

•

create liens on assets;

•

pay dividends on our Common Stock;

•

make certain investments, loans and advances;

•

repurchase or redeem capital stock;

•

make certain capital expenditures;

•

engage in acquisitions, mergers or consolidations; and

•

engage in certain transactions with subsidiaries and affiliates.

These covenants could limit our ability to plan for or react to market conditions, finance our operations, engage in strategic acquisitions or disposals or meet our capital needs or could otherwise restrict our activities or business plans. Our ability to comply with these covenants may be affected by events beyond our control. In addition, our credit facility also requires us to maintain compliance with certain financial ratios. Our inability to

comply with the required financial ratios or covenants could result in an event of default under our credit facility. A default, if not cured or waived, may permit acceleration of our indebtedness. In addition, our lenders could terminate their commitments to make further extensions of credit under our credit facility. If our indebtedness is accelerated, we cannot be certain that we will have sufficient funds to pay the accelerated indebtedness or that we will have the ability to refinance accelerated indebtedness on terms favorable to us or at all.

Our Articles of Incorporation and other agreements contain provisions that could discourage a takeover.

Our Articles of Incorporation authorize our Board of Directors to issue up to 10,000,000 shares of Preferred Stock in one or more series, to fix the rights, preferences, privileges and restrictions granted to or imposed upon any wholly unissued shares of Preferred Stock, to fix the number of shares constituting any such series and to fix the designation of any such series, without further vote or action by shareholders. The terms of any series of Preferred Stock, which may include priority claims to assets and dividends and special voting rights, could adversely affect the rights of the holders of our Common Stock and thereby reduce the value of our Common Stock. We have no present plans to issue shares of Preferred Stock. The issuance of Preferred Stock, coupled with the concentration of ownership in the directors and executive officers, could discourage certain types of transactions involving an actual or potential change in control of our company, including transactions in which the holders of Common Stock might otherwise receive a premium for their shares over then current prices, otherwise dilute the rights of holders of Common Stock and may limit the ability of such shareholders to cause or approve transactions which they may deem to be in their best interests, all of which could have a material adverse effect on the market price of our Common Stock. We have in place a stockholder rights plan, adopted in 2000, under which our shareholders are entitled to purchase shares of Preferred Stock under certain circumstances. The stockholder rights plan may have the effect of impeding or preventing certain types of transactions involving a change in control of our company that could be beneficial to the shareholders.

Our Articles of Incorporation limit the liability of our directors, which may limit the remedies we or our shareholders have available.

Our Articles of Incorporation provide that, pursuant to the California Corporations Code, the liability of our directors for monetary damages shall be eliminated to the fullest extent permissible under California law. This is intended to eliminate the personal liability of a director for monetary damages in an action brought by us, or in our right for breach of a director’s duties to us or our shareholders and may limit the remedies available to us or our shareholders. This provision does not eliminate the directors’ fiduciary duty and does not apply to liabilities for: (i) acts or omissions that involve intentional misconduct or a knowing and culpable violation of law; (ii) acts or omissions that a director believes to be contrary to the best interests of our company or our shareholders or that involve the absence of good faith on the part of the director; (iii) any transaction from which a director derived an improper personal benefit; (iv) acts or omissions that show a reckless disregard for the director’s duty to our company or our shareholders in circumstances in which the director was aware, or should have been aware, in the ordinary course of performing a director’s duties, of a risk of serious injury to our company or our shareholders; (v) acts or omissions that constitute an unexcused pattern of inattention that amounts to an abdication of the director’s duty to our company or our shareholders; (vi) certain transactions or the approval of transactions in which a director has a material financial interest; and (vii) approval of certain improper distributions to shareholders or certain loans or guarantees.

PROPERTIES

As of June 30, 2008, we owned three facilities. One is located in Hawthorne, California (approximately 88,000 square feet) and is primarily used by our Optoelectronics and Manufacturing division for administrative, manufacturing, engineering, sales and marketing functions. It also constitutes our corporate headquarters. We also own one building in Salfords, England (approximately 59,000 square feet), which is used by our Security and Healthcare divisions for manufacturing, engineering, sales and marketing functions. Additionally we own a facility in Ocean Springs, Mississippi (approximately 19,000 square feet), which is used by our Security and Optoelectronics and Manufacturing divisions for manufacturing, engineering, sales and marketing functions.

As of June 30, 2008, we leased all of our other facilities. The following table lists our principal physical properties (i.e., facilities greater than 50,000 square feet):


Location	Description of Facility	Approximate Square Footage	Expiration
Camarillo, California	Manufacturing, engineering, sales and marketing and service for our Optoelectronics and Manufacturing division	60,000	2010

Sunnyvale, California	Manufacturing, engineering, sales and marketing and service for our Security division	62,500	2012

Torrance, California	Manufacturing, engineering, sales and marketing and service for our Security division	91,900	2012

North Andover, Massachusetts	Manufacturing, engineering, sales and marketing and service for our Optoelectronics and Manufacturing division	71,700	2010

Issaquah, Washington (1)	Manufacturing, engineering, sales and marketing and service for our Healthcare division	202,600	2014

Suzhou, China	Manufacturing, engineering, sales and marketing and service for our Healthcare division	55,000	2012

Hyderabad, India (2)	Manufacturing and engineering for our Security, Healthcare and Optoelectronics and Manufacturing divisions	52,100	2009

Johor Bahru, Malaysia (3)	Manufacturing, engineering sales and service for our Security and Optoelectronics and Manufacturing divisions	93,000	2009

(1)

The lease of the 202,600 square foot facility in Issaquah, Washington is composed of two leases in the same facility. One lease covers a 107,000 square foot area within the facility and the other covers a 95,600 square foot area within the facility. Both leases expire in December 2014.

(2)

The lease of the 52,100 square foot facility in Hyderabad, India is composed of four leases in the same or in nearby facilities: (i) a 19,800 square foot facility lease that expires in 2009; (ii) a 19,600 square foot facility lease that expires in 2009; (iii) a 6,400 square foot facility lease that expires in 2009; (iv) and a 6,300 square foot facility that expires in 2009. We expect all four facility leases will be renewed on similar terms.

(3)

The lease of the 93,000 square foot facility in Johor Bahru, Malaysia is composed of two leases in nearby facilities: (i) a 76,000 square foot facility lease that expires in December 2008 and (ii) a 17,000 square foot facility lease that expires in January 2009. We expect that both the 76,000 square foot facility and 17,000 square foot facility leases will be renewed on similar terms.

We believe that our facilities are in good condition and are adequate to support our operations for the foreseeable future. We currently anticipate that we will be able to renew the leases that are scheduled to expire in the next few years on terms that are substantially the same as those currently in effect. However, even if we were not able to renew one or more of the leases, we believe that suitable substitute space is available to relocate any of the facilities. Accordingly, we do not believe that our failure to renew any of the leases that are scheduled to expire in the next few years will have a material adverse effect on our operations.

LEGAL PROCEEDINGS

In November 2002, L-3 Communications Corporation brought suit against us in the District Court for the Southern District of New York seeking a declaratory judgment that L-3 Communications Corporation had not breached its obligations to us concerning the acquisition of PerkinElmer’s Security Detection Systems Business. We asserted counterclaims against L-3 Communications Corporation for, among other things, fraud and breach of fiduciary duty. In May 2006, the jury in the case returned a verdict in our favor and awarded us $125 million in damages. The jury found that L-3 Communications Corporation had breached its fiduciary duty to us and had committed fraud. The jury awarded us $33 million in compensatory damages and $92 million in punitive damages. In addition, the jury also found that we had breached a confidentiality agreement and awarded L-3 Communications Corporation nominal damages of one dollar. On June 27, 2008, the United States Court of Appeals for the Second Circuit issued a summary order reversing in part, and vacating in part, the judgment of the district court, and remanding the case to the district court for further proceedings. The Second Circuit held that L-3 did not owe us a fiduciary duty as a matter of law and reversed the judgment of the district court on our claims for breach of fiduciary duty and constructive fraud. The Second Circuit vacated the judgment of the district court on our claim for actual fraud, and remanded that claim to the district court for further proceedings.

We are also involved in various other claims and legal proceedings arising out of the ordinary course of business which have not been previously disclosed in our quarterly and annual reports. In our opinion after consultation with legal counsel, the ultimate disposition of such proceedings will not likely have a material adverse effect on our financial position, future results of operations, or cash flows. In accordance with Statement of Financial Accounting Standards (SFAS) No. 5, “Accounting for Contingencies,” we have not accrued for loss contingencies relating to such matters because we believe that, although unfavorable outcomes in the proceedings may be possible, they are not considered by management to be probable or reasonably estimable. If one or more of these matters are resolved in a manner adverse to us, the impact on our results of operations, financial position and/or liquidity could be material.

As of August 25, 2008, there were approximately 124 holders of record of our Common Stock. This number does not include beneficial owners holding shares through nominees or in “street” name.

Dividend Policy

We have not paid any cash dividends since the consummation of our initial public offering in 1997 and anticipate that we will retain any available funds for use in the operation of our business. We do not currently intend to pay any cash dividends in the foreseeable future. Our Board of Directors will determine the payment of future cash dividends, if any. Certain of our current bank credit facilities restrict the payment of cash dividends and future borrowings may contain similar restrictions.

Issuer Purchases of Equity Securities

In March 1999, our Board of Directors authorized a stock repurchase program for the repurchase of up to 2 million shares of our Common Stock. In September 2004, we increased the number of shares available for repurchase under the stock repurchase program by 1 million shares. During the three months ended June 30, 2008, there were no shares repurchased under this program. As of June 30, 2008, 1,330,973 shares were available for repurchase under the program.

Equity Compensation Plans

The following table provides information concerning our equity compensation plans as of June 30, 2008.

Results of operations for fiscal years 2004 through 2008, and our financial position as of June 30, 2004, 2005, 2006, 2007 and 2008 incorporate the effect of several acquisitions, including that of Spacelabs Medical (as of March of 2004) and Del Mar Reynolds (as of July of 2006).

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

We are a vertically integrated designer and manufacturer of specialized electronic systems and components for critical applications. We sell our products in diversified markets, including homeland security, healthcare, defense and aerospace. We have three operating divisions: (a) Security, providing security and inspection systems; (b) Healthcare, providing patient monitoring, diagnostic cardiology and anesthesia systems; and (c) Optoelectronics and Manufacturing, providing specialized electronic components for affiliated end-products divisions, as well as for applications in the defense and aerospace markets, among others.

Security Division. Through our Security division, we design, manufacture and market security and inspection systems worldwide for sale primarily to U.S. and foreign government agencies. These products are used to inspect baggage, cargo, vehicles and other objects for weapons, explosives, drugs and other contraband as well as to screen people. Revenues from our Security division accounted for 36% of our total consolidated revenues for fiscal 2008.

Following the September 11, 2001 terrorist attacks, U.S. Government spending for the development and acquisition of security and inspection systems increased in response to the attacks and has continued at high levels during its global war on terrorism. This spending has had a favorable impact on our business. However, future levels of such spending could decrease as a result of changing budgetary priorities or could shift to products that we do not provide. Additionally, competition for contracts has become more intense in recent years as new competitors and technologies have entered this market.

Healthcare Division. Through our Healthcare division, we design, manufacture and market patient monitoring, diagnostic cardiology and anesthesia systems worldwide for sale primarily to hospitals and medical centers. Our products monitor patients in critical, emergency and perioperative care areas of the hospital and provide such information, through wired and wireless networks, to physicians and nurses who may be at the patient’s bedside, in another area of the hospital or even outside the hospital. Revenues from our Healthcare division accounted for 41% of our total consolidated revenues for fiscal 2008.

The healthcare markets in which we operate are highly competitive. We believe that our customers choose among competing patient monitoring, diagnostic cardiology and anesthesia products on the basis of product performance, functionality, value and service. We also believe that price has become an important factor in hospital purchasing decisions because of pressures they are facing to cut costs.

Optoelectronics and Manufacturing Division. Through our Optoelectronics and Manufacturing division, we design, manufacture and market optoelectronic devices and value-added manufacturing services worldwide for use in a broad range of applications, including aerospace and defense electronics, security and inspection systems, medical imaging and diagnostics, CT, fiber optics, telecommunications, gaming, office automation, computer peripherals and industrial automation. We also provide our optoelectronic devices and value-added manufacturing services to our own Security and Healthcare divisions. Revenues from our Optoelectronics and Manufacturing division accounted for approximately 23% of our total consolidated revenues for fiscal 2008.

Consolidated Results. We reported consolidated operating profit of $18.9 million for fiscal 2008, a significant improvement from the $42.2 million operating loss reported for fiscal 2007. This $61.1 million improvement was primarily due to: (i) a $90.8 million or 17% growth in revenue; (ii) cost-cutting and facility consolidation initiatives that we began in the second half of fiscal 2007, which have resulted in more efficient manufacturing activities and reduced selling, general and administrative expenses as a percentage of sales; and (iii) a reduction of impairment and restructuring charges from $36.4 million in fiscal 2007 to $4.7 million in fiscal 2008. The impairment and restructuring charges in fiscal 2007 consisted of (i) a $21.5 million charge associated with the impairment of certain intangible and fixed assets; (ii) $10.3 million of inventory charges following a review of our product portfolio; and (iii) $4.6 million of restructuring charges primarily related to the consolidation of several manufacturing processes and facilities among all of our segments. The restructuring charges in fiscal 2008 primarily resulted from additional and continuing consolidation activities of several manufacturing processes and facilities.

As noted above, during fiscal 2007, we undertook a review of our global operations as part of our on-going efforts to integrate recent acquisitions and rationalize our overall cost structure. The review resulted in the implementation of cost-cutting measures during the second half of fiscal 2007, resulting in approximately $17 million of pre-tax annualized cost savings, including a reduction of approximately 8% of our global workforce and the consolidation of multiple facilities. We realized a beneficial impact from these activities in the form of cost savings in fiscal 2008. In addition, during fiscal 2008, we identified additional cost savings opportunities that have been initiated and are expected to benefit future periods.

Acquisitions. Historically, an active acquisition program has been an important element of our corporate strategy. Our most recent significant acquisition occurred in the first quarter of fiscal 2007, when we purchased Del Mar Reynolds, a global manufacturer and distributor of cardiac monitoring systems. Since this transaction, however, we have not acquired other businesses and have instead focused greater attention on conducting a global review of our core businesses and technologies, and to fully integrate the acquisitions we made during the past several years. This global review and integration resulted in significant restructuring and impairment charges in fiscal 2007 and 2008. See Note 7 to Consolidated Financial Statements for further discussion. Looking forward, we continue to believe that an active acquisition program supports our long-term strategic direction. We look to acquisitions to strengthen our competitive position, expand our customer base and augment our considerable research and development programs. Through such efforts we aim to accelerate innovation, improve earnings and increase overall stockholder value.

The acquisition of businesses affects the comparability of financial results between fiscal periods. As a result, we have quantified, where appropriate, the impact of the businesses that we have recently acquired. See Note 2 of our Notes to Consolidated Financial Statements for additional information related to our recent acquisitions.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our Consolidated Financial Statements, which have been prepared in conformity with accounting principles generally accepted in the United States. Our preparation of these Consolidated Financial Statements requires us to make judgments and estimates that affect the reported amounts of assets and liabilities, 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. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. As a result, actual results may differ from such estimates. Our senior management has reviewed these critical accounting policies and related disclosures with the Audit Committee of our Board of Directors. The following summarizes our critical accounting policies and significant estimates used in preparing our Consolidated Financial Statements:

Revenue Recognition. We recognize revenue upon shipment of products when title and risk of loss passes, and when terms are fixed and collection is probable. In accordance with the terms of Securities and Exchange Commission Staff Accounting Bulletin No. 104, “Revenue Recognition” and FASB Emerging Issues Task Force

00-21 “Revenue Arrangements with Multiple Deliverables,” where installation services, if provided, are essential to the functionality of the equipment, we defer the portion of revenue for the sale attributable to installation until we have completed the installation. When terms of sale include subjective customer acceptance criteria, we defer revenue until the acceptance criteria are met. Concurrent with the shipment of the product, we accrue estimated product return reserves and warranty expenses. Critical judgments made by management related to revenue recognition include the determination of whether or not customer acceptance criteria are perfunctory or inconsequential. The determination of whether or not the customer acceptance terms are perfunctory or inconsequential impacts the amount and timing of the revenue that we recognize. Critical judgments also include estimates of warranty reserves, which are established based on historical experience and knowledge of the product.

We undertake projects that include the design, development and manufacture or fabrication of large, complex cargo and vehicle inspection systems that are specially customized to our customers’ specifications or that involve fixed-site construction. We record sales under such contracts under the percentage-of-completion method in accordance with FASB Statement of Position No. 81-1 “Accounting for Performance of Construction-Type and Certain Production-Type Contracts.” We record costs and estimated revenues as we perform work based on the percentage that incurred costs bear to estimated total costs, utilizing the most recent estimates of costs. If our current contract estimate indicates a loss, we make a provision for the total anticipated loss in the current period. Critical estimates made by management related to revenue recognition under the percentage-of-completion method include the estimation of costs at completion and the determination of the overall margin rate on the specific project.

We recognize revenues from separate service maintenance contracts ratably over the term of the agreements. For other services, we recognize service revenues as we perform the services. Deferred revenue for services arises from advance payments received from customers for services not yet performed. We record billed shipping and handling fees as revenue and the associated costs as cost of goods sold.

Allowance for Doubtful Accounts. The allowance for doubtful accounts involves estimates based on management’s judgment, review of individual receivables and analysis of historical bad debts. We monitor collections and payments from our customers and we maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances could be required.

Inventory. Inventory is stated at the lower of cost or market. Cost is determined on the first-in, first-out method. We write down inventory for slow-moving and obsolete inventory based on assessments of future demands, market conditions and customers who may be experiencing financial difficulties. If these factors were to become less favorable than those projected, additional inventory write-downs could be required.

Income Taxes. Effective July 1, 2007, we adopted FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (FIN 48). FIN 48 prescribes a two-step process for the financial statement measurement and recognition of a tax position taken or expected to be taken in a tax return. The first step involves the determination of whether it is more likely than not (greater than 50 percent likelihood) that a tax position will be sustained upon examination, based on the technical merits of the position. The second step requires that any tax position that meets the more-likely-than-not recognition threshold be measured and recognized in the financial statements at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. FIN 48 also provides guidance on the accounting for related interest and penalties, financial statement classification and disclosure. The cumulative effect of applying FIN 48 was reported as an adjustment to the opening balance of retained earnings in the period of adoption. See Note 10 of our Notes to Consolidated Financial Statements for additional information regarding the impact of FIN 48.

Deferred Tax Asset Valuation Allowance. We record a valuation allowance to reduce our deferred tax assets when it is more likely than not, based upon currently available evidence and other factors, that we will not realize some portion or all of our deferred tax assets. We base our determination of the need for a valuation

allowance on an on-going evaluation of past and current evidence, including, among other things, historical earnings, estimates of future earnings, the backlog of customer orders and the expected timing of deferred tax asset reversals. We charge or credit adjustments to the valuation allowance to income tax expense in the period in which we make these determinations. If we determine that we will be able to realize our deferred tax assets in the future in excess of its net recorded amount, then we make an adjustment to our deferred tax assets to increase net income in the period that we make this determination. Likewise, if we determine that we will not be able to realize all or part of our net deferred tax assets in the future, then we establish a valuation allowance for the deferred tax asset and reduce net income in the period that we make this determination.

Business Combinations. In accordance with present business combination accounting, we allocate the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed as well as to in-process research and development based on their estimated fair values. We engage third-party appraisal firms to assist management in determining the fair values of certain assets acquired and liabilities assumed in material transactions. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Management makes estimates of fair value based upon assumptions believed to be reasonable. These estimates are based on historical experience and information obtained from the management of the acquired companies and is inherently uncertain.

Other significant estimates associated with the accounting for acquisitions include restructuring costs. Restructuring costs are primarily composed of severance costs, costs of consolidating facilities and contract termination costs. Restructuring expenses are based upon plans that have been committed to by management, but which are subject to refinement. Estimated restructuring expenses may change as management executes the plan. Decreases to the cost estimates of executing the plans associated with pre-merger activities of the companies we acquire are recorded as an adjustment to goodwill indefinitely, whereas increases to the estimates are recorded as an adjustment to goodwill during the purchase price allocation period (generally within one year of the acquisition date) and as operating expenses thereafter.

For a given acquisition, we may identify certain pre-acquisition contingencies. If, during the purchase price allocation period, we are able to determine the fair value of a pre-acquisition contingency, we will include that amount in the purchase price allocation. If, as of the end of the purchase price allocation period, we are unable to determine the fair value of a pre-acquisition contingency, we will evaluate whether to include an amount in the purchase price allocation based on whether it is probable that a liability had been incurred and whether an amount can be reasonably estimated. With the exception of unresolved tax matters, after the end of the purchase price allocation period, any adjustment to amounts recorded for a pre-acquisition contingency will be included in our operating results in the period in which the adjustment is determined.

Impairment of Long-Lived Assets. We test goodwill for impairment at the reporting unit level at least annually and more frequently upon the occurrence of certain events. For purposes of testing for goodwill impairment, we have determined that we have four reporting units for goodwill impairment review purposes, consisting of the Security division, Optoelectronics and Manufacturing division, and two reporting units within the Healthcare division. We test goodwill for impairment annually during the second fiscal quarter using a two-step process. First, we determine if the carrying amount of any of the reporting units exceeds its fair value. We use a discounted cash flows method to make this determination for our Security, Healthcare and Optoelectronics and Manufacturing divisions. Until January 24, 2008, we used a market value method for our Healthcare division (based on the market price of the Healthcare division’s stock which was publicly traded until we cancelled Spacelabs Healthcare’s AIM listing on January 24, 2008). If these methods indicate a potential impairment of goodwill associated with the respective reporting unit, we then compare the implied fair value of the goodwill associated with the respective reporting unit to its carrying amount to determine if there is an impairment loss. We performed this annual impairment test for goodwill during the second quarter of fiscal 2008 and concluded that there was no impairment of goodwill.

We evaluate long-lived assets, including intangible assets other than goodwill, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. An impairment is considered to exist if the total estimated future cash flows on an undiscounted basis are less than the carrying amount of the assets. If an impairment does exist, we measure the impairment loss and record it based on discounted estimated future cash flows. In estimating future cash flows, we group assets at the lowest level for which there are identifiable cash flows that are largely independent of cash flows from other asset groups. Our estimate of future cash flows is based upon, among other things, certain assumptions about expected future operating performance, growth rates and other factors.

Stock-Based Compensation Expense. Effective July 1, 2005, we adopted SFAS 123(R), “Share-Based Payment” (SFAS 123(R)), using the modified prospective approach and therefore have not restated results for prior periods. Under this approach, awards that are granted, modified or settled after July 1, 2005 have been and will be measured and accounted for in accordance with SFAS 123(R). Unvested awards that were granted prior to July 1, 2005, will continue to be accounted for in accordance with SFAS No. 123, “Accounting for Stock-Based Compensation” (SFAS 123), as amended by SFAS No. 148, “Accounting for Stock-Based Compensation—Transition and Disclosure—an amendment of FASB Statement No. 123” (SFAS 148), except that compensation cost will be recognized in our results of operations. Pursuant to the provisions of SFAS 123(R), we record stock-based compensation as a charge to earnings net of the estimated impact of forfeited awards. As such, we recognize stock-based compensation cost only for those stock-based awards that are estimated to ultimately vest over their requisite service period, based on the vesting provisions of the individual grants.

The process of estimating the fair value of stock-based compensation awards and recognizing stock-based compensation cost over their requisite service period involves significant assumptions and judgments. We estimate the fair value of stock option awards on the date of grant using the Black-Scholes option-valuation model which requires that we make certain assumptions regarding: (i) the expected volatility in the market price of our Common Stock; (ii) dividend yield; (iii) risk-free interest rates; and (iv) the period of time employees are expected to hold the award prior to exercise (referred to as the expected holding period). In addition, SFAS 123(R) requires us to estimate the expected impact of forfeited awards and recognize stock-based compensation cost only for those awards expected to vest. If actual forfeiture rates differ materially from our estimates, stock-based compensation expense could differ significantly from the amounts we have recorded in the current period. We periodically review actual forfeiture experience and revise our estimates, as necessary. We recognize the cumulative effect on current and prior periods of a change in the estimated forfeiture rate as compensation cost in earnings in the period of the revision. As a result, if we revise our assumptions and estimates, our stock-based compensation expense could change materially in the future. See Note 9 (Stock-based Compensation) to the Consolidated Financial Statements for a further discussion of stock-based compensation.

Legal and Other Contingencies. We are currently involved in various claims and legal proceedings. Each fiscal quarter, we review the status of each significant legal dispute to which we are a party and assess our potential financial exposure, if any. If the potential financial exposure from any claim or legal proceeding is considered probable and the amount can be reasonably estimated, we accrue a liability for the estimated loss. Significant judgment is required in both the determination of probability and the determination as to whether an exposure is reasonably estimable. Because of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to our pending claims and litigation and revise our estimates accordingly. Such revisions in the estimates of the potential liabilities could have a material impact on our results of operations and financial position.

Net Revenues

The table below and the discussion that follows are based upon the way we analyze our business. See Note 15 to the Consolidated Financial Statements for additional information about business segments.


	2006			% of Net Sales		2007			% of Net Sales		2008			% of Net Sales		2006-2007 % Change		2007-2008 % Change
	(Dollars in millions)
Security	$	135.1		30	%	$	186.6		35	%	$	225.8		36	%	38	%	21	%
Healthcare		220.6		49	%		233.2		44	%		256.7		41	%	6	%	10	%
Optoelectronics / Manufacturing		125.9		28	%		150.5		28	%		187.7		30	%	20	%	25	%
Intercompany Revenue		(28.9	)	(7	)%		(38.0	)	(7	)%		(47.1	)	(7	)%	31	%	24	%

Total Sales	$	452.7				$	532.3				$	623.1				18	%	17	%

Fiscal 2008 Compared with Fiscal 2007. Net revenues for fiscal 2008 increased $90.8 million, or 17%, to $623.1 million from $532.3 million for fiscal 2007.

Revenues for the Security division for fiscal 2008 increased $39.2 million, or 21%, to $225.8 million, from $186.6 million for fiscal 2007. The increase was primarily attributable to a $15.9 million, or 12%, increase in sales of baggage and parcel inspection and people screening systems and a $23.4 million, or 45%, increase in sales of cargo and vehicle inspection systems.

Revenues for the Healthcare division for fiscal 2008 increased $23.5 million, or 10%, to $256.7 million, from $233.2 million for fiscal 2007. The increase was primarily attributable to a $16.2 million, or 13%, increase in sales of patient monitoring equipment, mainly in North America; higher Healthcare service, supplies and accessories sales of $6.5 million, or 15%; and an increase in sales of diagnostic cardiology equipment of $3.7 million, or 62%. These increases were partially offset by lower clinical trials services revenue, which decreased by $2.2 million.

Revenues for the Optoelectronics and Manufacturing division for fiscal 2008 increased $37.2 million, or 25%, to $187.7 million, from $150.5 million for fiscal 2007. The increase was primarily attributable to an increase in contract manufacturing sales of $44.2 million, or 72%, including product shipments under a significant defense-industry related contract that is expected to continue into fiscal 2009, and was partially offset by decreases in commercial optoelectronics sales of $3.9 million, or (5)%, and weapons simulation sales of $3.3 million, or (41)%. In addition, for fiscal 2008, the division recorded intercompany sales of $47.1 million, compared to $38.0 million in fiscal 2007. This increase resulted from sales by our Optoelectronics and Manufacturing division to our Security and Healthcare divisions required to support higher sales by such divisions. Intercompany sales by our Optoelectronics and Manufacturing division to our Security and Healthcare divisions are eliminated in consolidation.

Fiscal 2007 Compared with Fiscal 2006. Net revenues for fiscal 2007 increased $79.6 million, or 18%, to $532.3 million, from $452.7 million for fiscal 2006.

Revenues for the Security division for fiscal 2007 increased $51.5 million, or 38%, to $186.6 million, from $135.1 million for fiscal 2006. The increase was primarily attributable to a $28.1 million, or 26%, increase in sales of baggage and parcel inspection and people screening systems and a $23.4 million, or 81%, increase in sales of cargo and vehicle inspection systems.

Revenues for the Healthcare division for fiscal 2007 increased $12.6 million, or 6%, to $233.2 million, from $220.6 million for fiscal 2006. The increase was primarily attributable to the inclusion of $28.4 million of revenues from Del Mar Reynolds, a business that we acquired in July 2006, partially offset by a decline in patient monitoring sales of $13.6 million and a decline in anesthesia delivery sales of approximately $0.8 million.

Revenues for the Optoelectronics and Manufacturing division for fiscal 2007 increased $24.6 million, or 20%, to $150.5 million, from $125.9 million for fiscal 2006. The increase was primarily attributable to an increase in commercial optoelectronic sales of $6.9 million and an increase in contract manufacturing sales of $14.5 million due primarily to the inclusion of revenues from a small acquisition in July 2006. In addition, for fiscal 2007, the division recorded intercompany sales of $38.0 million, compared to $28.9 million in the comparable prior-year period. Such sales, which are made to the Security and Healthcare divisions, are eliminated in consolidation.

Gross Profit


	2006		% of Net Sales		2007		% of Net Sales		2008		% of Net Sales
	(Dollars in millions)
Gross profit	$	176.6	39.0	%	$	178.2	33.5	%	$	219.0	35.1	%

Fiscal 2008 Compared with Fiscal 2007. Gross profit increased $40.8 million, or 23%, to $219.0 million for fiscal 2008, from $178.2 million for fiscal 2007. The gross margin increased to 35.1% in fiscal 2008 from 33.5% in fiscal 2007. The increase in gross profit was the result of both a 17% increase in total revenue in fiscal 2008 compared to fiscal 2007, which resulted in more efficient manufacturing processes through better leveraging of fixed manufacturing costs for several of our products, and the recording in fiscal 2007 of a $10.3 million inventory impairment charge that reduced gross profit in the second quarter of fiscal 2007. During fiscal 2007, inventory impairment charges had the effect of reducing the gross margin by 1.9%. Excluding the impact of the aforementioned charge, our gross margin in fiscal 2008 decreased by 0.3% versus fiscal 2007. Although we experienced gross margin improvement in our Healthcare division, the change in the product mix in both the Security and Optoelectronics and Manufacturing divisions offset the impact of this increase. The factors that generally increased gross margins included: (i) growth in the revenues of our Healthcare division, primarily in patient monitoring systems, which generally carry higher gross margins than many of our other products; (ii) cost savings in our Healthcare division from restructuring activities initiated in fiscal 2007 and reduced manufacturing costs in our Optoelectronics and Manufacturing division passed along to the Healthcare division the intercompany sales; and (iii) gross margin improvements in cargo and vehicle inspection products in our Security division associated with manufacturing efficiencies. Factors that offset such increases in our consolidated gross margins included increased contract manufacturing revenues in our Optoelectronics and Manufacturing division and increased sales of cargo and vehicle inspection systems sales in our Security division, both of which generally carry a lower gross margin than our other products and services.

Fiscal 2007 Compared with Fiscal 2006. Gross profit increased $1.6 million, or 1%, to $178.2 million for fiscal 2007, from $176.6 million for fiscal 2006. The gross margin decreased to 33.5% in fiscal 2007 from 39.0% in fiscal 2006. This decrease was partially attributable to the recording of $10.3 million of inventory charges during fiscal 2007, following a global review of operations during which we determined that certain finished goods inventory values, primarily associated with cargo and vehicle inspection products developed by our Security division, were impaired. These inventory charges reduced our gross margin by 1.9%. The decline in gross margin was also attributable to: (i) lower gross margins within our Security division due to an increase in sales of cargo and vehicle inspection products that were sold at lower gross margins than our baggage and parcel inspection and people screening systems; (ii) reduced patient monitoring systems sales by our Healthcare division, which generally carry higher gross margins than many of our other products; (iii) growth in sales of contract manufacturing services and commercial optoelectronic products by our Optoelectronic and Manufacturing division, which products and services generally carry lower gross margins than the products and services of the other divisions; and (iv) cost overruns incurred during the performance of certain long-term contracts for the development and manufacture of weapons simulation systems by our Optoelectronics and Manufacturing division.

Selling, General and Administrative

Fiscal 2008 Compared with Fiscal 2007. Selling, general and administrative (SG&A) expenses consisted primarily of compensation paid to sales, marketing and administrative personnel, professional service fees and marketing expenses. For fiscal 2008, despite revenue growth of 17%, SG&A expenses were virtually flat as compared to fiscal 2007. We accomplished this by successfully leveraging our SG&A infrastructure while focusing on cost containment initiatives. Such efficiencies led to a 4% decrease in SG&A as a percentage of sales from 28.1% in fiscal 2007 to 24.1% in fiscal 2008.

Fiscal 2007 Compared with Fiscal 2006. For fiscal 2007, SG&A expenses increased by $10.9 million, or 8%, to $149.9 million, from $139.0 million for fiscal 2006. As a percentage of revenues, SG&A expenses for fiscal 2007 decreased to 28.1%, from 30.8% in fiscal 2006. The increase in SG&A expenses was primarily attributable to: (i) approximately $13.5 million in increased Healthcare division spending, primarily to support of Del Mar Reynolds, a business that we acquired in July 2006 and (ii) an increase of $4.3 million to support growth in the Optoelectronic and Manufacturing division. This increase in SG&A expenses was partially offset by a $5.7 million reduction in legal expenses as we concluded during fiscal 2007 certain litigation matters involving Science Applications International Corporation and General Electric Corporation as well as reductions in the level of litigation activity associated with an ongoing lawsuit with L-3 Communications Corporation.

Research and Development

Our Security and Healthcare divisions have historically invested substantial amounts in research and development. We intend to continue this trend in future years, although specific programs may or may not continue to be funded and funding levels may fluctuate.

Fiscal 2008 Compared with Fiscal 2007. Research and development expenses include research related to new product development and product enhancement expenditures. For fiscal 2008, such expenses increased by $0.9 million, or 2%, to $45.3 million, from $44.4 million for fiscal 2007. As a percentage of revenues, research and development expenses were 7.3% in fiscal 2008, compared to 8.4% in fiscal 2007. The increase in research and development expenses was primarily attributable to increased spending in support of next generation products in our Healthcare division.

Fiscal 2007 Compared with Fiscal 2006. For fiscal 2007, research and development expenses increased by $8.5 million, or 24%, to $44.4 million, from $35.9 million for fiscal 2006. As a percentage of revenues, research and development expenses were 8.4% for fiscal 2007, compared to 7.9% for fiscal 2006. The increase in research and development expenses was primarily attributable to: (i) incremental spending of approximately $6.6 million by our Healthcare division primarily to support of Del Mar Reynolds, a business we acquired in July 2006, and in support of next generation patient monitoring products and (ii) increased investment by our Security division of $3.0 million, primarily to support new hold (checked) baggage screening products. These increases were partially offset by a $1.0 million reduction in Optoelectronic and Manufacturing division spending.

Impairment, Restructuring, and Other Charges

Beginning in fiscal 2007 and continuing through fiscal 2008, we initiated a series of restructuring activities, which were intended to realign our global capacity and infrastructure with demand by our customers and fully integrate acquisitions made in the last several years, thereby improving our operational efficiency. These activities included reducing excess workforce and capacity, consolidating and relocating certain manufacturing facilities and reviewing the value of certain technologies and product lines. The overall objectives of the restructuring activities were to lower costs and better utilize our overall existing manufacturing capacity. To date, these efforts have helped enhance our ability to improve operating margins, retain and expand existing relationships with customers and attract new business. We may utilize similar measures in the future to realign our operations to further increase our operating efficiencies, which may materially affect our future operating results.

Fiscal 2008 Compared with Fiscal 2007. During fiscal 2008, we incurred $4.7 million of restructuring charges, primarily related to headcount reductions and facility closures. Of the $4.7 million of restructuring costs, $2.0 million was recorded within our Healthcare division, $2.3 million within our Security division and $0.4 million within our Optoelectronics and Manufacturing division. This compared to combined impairment and restructuring charges of $36.4 million in fiscal 2007, of which $26.1 million was reported in operating expenses and $10.3 million was reported in cost of goods sold, as further explained below.

Fiscal 2007 Compared with Fiscal 2006. During fiscal 2007, as part of a global review of our operations, we assessed the value of certain technologies and product lines. As a result of this assessment, we recorded charges of $31.8 million. This amount consists of (i) $21.5 million of asset impairment of certain identifiable intangible and fixed assets and (ii) $10.3 of inventory charges, primarily related to finished goods inventory. Of the $21.5 million of impairment charges related to intangible and fixed assets, $21.3 million was recorded within our Security division and $0.2 million was recorded within our Optoelectronics and Manufacturing division. Of the $10.3 million of impairment charges related to inventory, $9.9 million was recorded within our Security division and $0.4 million was recorded within our Optoelectronics and Manufacturing division. We have reflected such inventory charges in cost of goods sold in our Consolidated Financial Statements. Additionally, we incurred $4.6 million of restructuring charges related to headcount reductions, office closures, and similar termination issues. Of the $4.6 million of restructuring costs, $1.8 million was recorded within our Healthcare division, $2.0 million within our Security division, $0.6 million within our Optoelectronics and Manufacturing division and $0.2 million within the corporate segment. In fiscal 2006, restructuring charges totaled $0.8 million and were associated with the consolidation of certain facilities.

Other Income

In fiscal 2007, we received $15.0 million in settlement of a dispute associated with our acquisition in fiscal 2004 of Spacelabs Medical, and $0.8 million in settlement of a dispute with a competitor of our Optoelectronics and Manufacturing division.

Interest Expense

Fiscal 2008 Compared to Fiscal 2007. In fiscal 2008, we incurred interest expense of $4.8 million, compared to $4.6 million in fiscal 2007. The increase was primarily attributable to additional debt incurred to finance investments in inventory and the repurchase of Spacelabs Healthcare stock in fiscal 2008. The impact of this increased borrowing was partially offset by more favorable cost of borrowing associated with a new credit facility that we entered into in July 2007 and lower, market driven interest rates.

Fiscal 2007 Compared to Fiscal 2006. In fiscal 2007, we incurred interest expense of $4.6 million, compared to $1.6 million in fiscal 2006. The increase was primarily attributable to increases in borrowings used to fund our acquisition of Del Mar Reynolds in July 2006 and to fund working capital requirements

Provision (Benefit) for Income Taxes

The effective tax rate for a particular period varies depending on a number of factors including (i) the mix of income earned in various tax jurisdictions, each of which applies a unique range of income tax rates and income tax credits, (ii) changes in previously established valuation allowances for deferred tax assets (changes are based upon our current analysis of the likelihood that these deferred tax assets will be realized), (iii) the level of non-deductible expenses, and (iv) tax holidays granted to certain of our international subsidiaries.

Fiscal 2008 Compared to Fiscal 2007. In fiscal 2008, our income tax expense was $0.6 million, compared to a benefit of $12.9 million for fiscal 2007. Included within the fiscal 2008 tax expense was a net tax benefit of $3.9 million, resulting from various nonrecurring items impacting the tax provision, including a $4.3 million tax benefit due to a change in our investment holding strategy for Spacelabs, as discussed in Note 10 to the Consolidated Financial Statements, and $0.4 million expense related to FIN 48. The effective income tax rate for fiscal 2008 was 4.0%. However, excluding the impact of these nonrecurring items, the effective tax rate for fiscal 2008 was 31.3%, compared to 42.3% for fiscal 2007. Our provision for income taxes is dependent on the mix of income from U.S. and foreign locations due to tax rate differences among such countries as well the impact of permanent taxable differences. Due to higher levels of profitability in fiscal 2008, the impact of permanent differences between book and tax accounting has a smaller impact on the effective tax rate in fiscal 2008 than in fiscal 2007, thus, shifting our effective tax rate closer to the statutory rates in the tax jurisdictions in which we operate.

Fiscal 2007 Compared to Fiscal 2006. In fiscal 2007, we recorded an income tax benefit of $12.9 million, or 42.3% of our pre-tax loss, compared to $1.1 million of income tax expense or 216.3% of pre-tax income in fiscal 2006. The change in the effective tax rate was primarily attributable to (i) additional research and development tax credits in fiscal 2007 and (ii) the repatriation of dividend income from certain of our foreign subsidiaries in fiscal 2006, which did not occur in fiscal 2007.

Liquidity and Capital Resources

To date, we have financed our operations primarily from proceeds from equity issuances and our credit facilities. Cash and cash equivalents totaled $18.2 million at June 30, 2008, an increase of $2.2 million from $16.0 million at June 30, 2007. The changes in our working capital and cash and cash equivalent balances are described below.


	2006		2007		2008		2006-2007 % Change		2007-2008 % Change
	(Dollars in millions)
Working capital	$	162.2	$	158.7	$	195.0	(2	)%	23	%
Cash and cash equivalents		13.8		16.0		18.2	16	%	14	%

Working Capital

Fluctuations in our working capital are primarily a result of two factors: (i) net earnings or losses and (ii) our debt structure. In fiscal 2008, the $36.3 million increase in working capital resulted from both net earnings of $13.9 million and from a net working capital infusion of approximately $23 million as a result of entering into a new credit facility. (See Note 8 to the Consolidated Financial Statements for further discussion.) In fiscal 2007, the $3.5 million decrease in working capital resulted from a net loss of $18.9 million, offset by a net working capital infusion of $17.3 million from the issuance of debt.

Cash Used in Operating Activities.

Cash flows from operating activities can fluctuate significantly from period to period as net income (loss), tax timing differences, and other items can significantly impact cash flows. Our largest source of operating cash flows is cash collections from our customers following the sale of our products and services. Our primary uses of cash for operating activities are for purchasing inventory in support of the products that we sell, personnel related expenditures, facilities costs and payments for general operating matters.

Fiscal 2008 Compared to Fiscal 2007. Cash used in operating activities was $0.7 million, a decrease of $1.6 million from fiscal 2007 when our cash used in operating activities was $2.3 million. This improvement is the result of a $32.7 million increase in net income in fiscal 2008. This was offset by significant investments made, primarily in inventory in our Security division to support business growth and an increase in accounts receivable resulting from very strong sales in the fourth quarter of fiscal 2008 of $171.2 million as compared to $152.8 million in the fourth quarter of fiscal 2007.

Fiscal 2007 Compared with Fiscal 2006. Cash used in operating activities decreased $9.9 million in fiscal 2007 compared to fiscal 2006, primarily as a result of reduced growth in accounts receivables and inventory due to additional emphasis placed upon working capital management. This improvement in working capital management was partially offset by lower net income before non-cash charges.

Cash Used in Investing Activities

The changes in cash flows from investing activities primarily relate to acquisitions as well as to capital expenditures and other assets to support our growth.

Fiscal 2008 Compared to Fiscal 2007. Cash flows used in investing activities was $29.8 million in fiscal 2008, a decrease of $0.4 million as compared to cash used in investing activities of $30.2 million. During fiscal 2008, we used $12.1 million in cash for capital expenditures, compared to $15.3 million for capital expenditures in fiscal 2007. During fiscal 2008, we used $15.7 million to repurchase Spacelabs Healthcare stock, compared to $4.5 million that we used for the same purpose in fiscal 2007. In fiscal 2007, we used approximately $22.8 million of cash to acquire Del Mar Reynolds, net of certain adjustments. The usage of cash during fiscal 2007 was partially offset by a $15.0 million payment that we received from General Electric Corporation in settlement of a dispute regarding an adjustment of the purchase price associated with our acquisition of Spacelabs Medical in March 2004.

Fiscal 2007 Compared with Fiscal 2006. Cash flows used in investing activities increased $13.9 million in fiscal 2007, primarily due to (i) increases in cash used in acquisitions of $22.8 million, primarily associated with the Del Mar Reynolds transaction in July 2006 and (ii) the buyback of stock in our Spacelabs Healthcare

subsidiary of $4.5 million. Such changes were partially offset by a $15.0 million payment to us in settlement of a dispute associated with our acquisition of Spacelabs Medical in fiscal 2004 as well as a $0.8 million reduction in capital expenditures in the normal course of business.

Cash Provided by Financing Activities

The changes in cash flows from financing activities primarily relate to (i) borrowings and payments under debt obligations, (ii) the issuance of and/or repurchase of stock in our Spacelabs Healthcare subsidiary, and (iii) the exercise activity in our equity participation and employee stock purchase plans.

Fiscal 2008 Compared to Fiscal 2007. Cash provided by financing activities was $33.0 million in fiscal 2008, a $2.8 million decrease, compared to $35.8 million in fiscal 2007. In fiscal 2008, the source of such funds was a new credit facility that we entered into in July 2007. (See further discussion of the new credit facility under “Borrowings,” below.) The proceeds of this debt were used primarily to repurchase Spacelabs Healthcare stock and to fund an investment in inventory in our Security division. In fiscal 2007, the cash provided by financing activities primarily consisted of proceeds of $25.4 million from a term loan that we entered in to fund the acquisition of Del Mar Reynolds and $5.9 million drawn from our revolving lines of credit to fund operations.

Fiscal 2007 Compared with Fiscal 2006. Cash flows provided by financing activities increased $9.1 million in fiscal 2007, primarily due to (i) an increase in long-term debt of $19.4 million which was primarily utilized to fund the acquisition of Del Mar Reynolds, (ii) an increase in borrowings under bank lines of credit of $10.8 million to support working capital requirements and (iii) an increase in proceeds of $3.5 million from the exercise of stock options and the purchase of stock under our employee stock purchase plan. This increase in cash flows from financing activities in fiscal 2007 was partially offset by cash proceeds of $26.3 million received from the initial public offering of a minority interest in Spacelabs Healthcare in fiscal 2006 as compared to no such public offering in fiscal 2007.

Borrowings

In July 2007, we entered into a credit agreement with certain lenders. The agreement provided for an $89.5 million credit facility, which was subsequently increased to $124.5 million in June 2008. The new credit agreement replaced former U.S. dollar credit agreements, which were repaid and terminated simultaneously with the close of the new agreement. The new credit agreement consists of a $74.5 million five-year revolving credit facility, including a $45 million sub-limit for letters-of-credit, and a $50 million five-year term loan. Borrowings under this facility bear interest at either (a) the U.S. dollar-based London Interbank Offered Rate (LIBOR) plus between 2.00% and 2.50% or (b) the bank’s prime rate plus between 1.00% and 1.50%. The rates are determined based on our consolidated leverage ratio. As of June 30, 2008, the effective weighted average interest rate under the credit agreement was 5.0% per annum. Our borrowings under the credit agreement are guaranteed by substantially all of our direct and indirect wholly-owned subsidiaries and are secured by substantially all of our assets and by the assets of our subsidiaries. The agreement contains various representations, warranties, affirmative, negative and financial covenants, and conditions of default customary for financing agreements of this type. As of June 30, 2008, $47.8 million was outstanding under the term loan, $14.0 million was outstanding under the revolving credit facility, and $3.6 million was outstanding under the letter-of-credit facility.

Several of our foreign subsidiaries maintain bank lines-of-credit, denominated in local currencies, to meet short-term working capital requirements and for the issuance of letters-of-credit. As of June 30, 2008, the total amount available under these various credit facilities was $34.8 million with a total cash borrowing sub-limit of $8.7 million, of which $4.7 million was outstanding. The weighted average interest rate of these facilities was 7.1% per annum at June 30, 2008.

In December 2004, we entered into a bank loan of $5.3 million to fund the acquisition of land and buildings in the U.K. The loan is payable over a 20-year period, with quarterly installments of £34,500 (approximately $69,000 as of June 30, 2008). The loan bears interest at British pound-based LIBOR plus 1.2%, payable on a quarterly basis. As of June 30, 2008, $4.5 million remained outstanding under this loan at an interest rate of 7.2% per annum.

The following is a summary of our contractual obligations and commitments at June 30, 2008 (in thousands):

(1)

We have presented the outstanding balance of $18.7 million on bank lines of credit at June 30, 2008, as due within less than one year in order to conform to the classification in the accompanying Consolidated Financial Statements. In addition, our total debt obligations exclude interest costs due to their variable nature.

We anticipate that existing cash borrowing arrangements and future access to capital markets should be sufficient to meet our cash requirements for the foreseeable future. However, our future capital requirements will depend on many factors, including future business acquisitions, litigation, stock repurchases and levels of research and development spending, among other factors and the adequacy of available funds will depend on many factors, including the success of our businesses in generating cash, continued compliance with financial covenants contained in our credit facility, and the capital markets in general, among other factors.

Stock Repurchase Program

Our Board of Directors has authorized a stock repurchase program under which we may repurchase up to 3,000,000 shares of our Common Stock. During fiscal 2008, we did not repurchase any shares under this program. As of June 30, 2008, 1,330,973 shares were available for additional repurchase under the program. We retire the treasury shares as they are repurchased and record them as a reduction in the number of shares of Common Stock issued and outstanding in our Consolidated Financial Statements.

Off Balance Sheet Arrangements

As of June 30, 2008, we had no off balance sheet arrangements other than those previously disclosed as defined in Item 303(a)(4) of Regulation S-K.

New Accounting Pronouncements

For information with respect to new accounting pronouncements and the impact of these pronouncements on our Consolidated Financial Statements, see Note 1 to Consolidated Financial Statements.

Related-Party Transactions

In 1994, we, together with an unrelated company, formed ECIL-Rapiscan Security Products Limited, a joint venture organized under the laws of India. We own a 36% interest in the joint venture, our Chairman and Chief Executive Officer owns a 10.5% interest, and our Executive Vice President and the President of our Security division owns a 4.5% ownership interest. Our initial investment was $0.1 million. For the years ended June 30, 2006, 2007 and 2008 our equity earnings in the joint venture amounted to $0.4 million, $0.3 million and $0.4 million, respectively. We, our Chairman and Chief Executive Officer, and our Executive Vice President and the

President of our Security division collectively control less than 50% of the board of directors voting power in the joint venture. As a result, we account for the investment under the equity method of accounting. The joint venture was formed for the purpose of the manufacture, assembly, service and testing of security and inspection systems and other products. Some of our subsidiaries are suppliers to the joint venture, which in turn manufactures and sells the resulting products. Sales to the joint venture partner for fiscal 2006, 2007, and 2008 were approximately $0.1 million, $0.5 million and $1.6 million, respectively.

We have contracted with entities owned by members of our Board of Directors and/or their family members to provide messenger services, auto rental and printing services. Included in cost of sales and selling, general and administrative expenses for the fiscal 2006, 2007 and 2008, are approximately $60,000, $50,000 and $54,000, respectively, for messenger service and auto rental; and $80,000, $50,000 and $42,000, respectively, for printing services.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

We are exposed to certain market risks, which are inherent in our financial instruments and arise from transactions entered into in the normal course of business. We may enter into derivative financial instrument transactions in order to manage or reduce market risk in connection with specific foreign-currency-denominated transactions. We do not enter into derivative financial instrument transactions for speculative purposes.

We are subject to interest rate risk on our short-term borrowings under our bank lines of credit. Borrowings under these lines of credit do not give rise to significant interest rate risk because these borrowings have short maturities and are borrowed at variable interest rates. Historically, we have not experienced material gains or losses due to interest rate changes.

Foreign Currency

We maintain the accounts of our operations in each of the following countries in the following currencies: Finland, France, Germany, Italy and Greece (Euros), Singapore (Singapore dollars and U.S. dollars), Malaysia (Malaysian ringgits), United Kingdom (U.K. pounds), Norway (Norwegian kroners), India (Indian rupees), Indonesia (Indonesian rupiah), Hong Kong (Hong Kong dollars), China (Chinese renminbi), Canada (Canadian dollars), Australia (Australian dollars) and Cyprus (Cypriot pounds). Foreign currency financial statements are translated into U.S. dollars at fiscal year-end rates, with the exception of revenues, costs and expenses, which are translated at average rates during the reporting period. We include gains and losses resulting from foreign currency transactions in income, while we exclude those resulting from translation of financial statements from income and include them as a component of accumulated other comprehensive income (AOCI). Transaction gains and losses which were included in our consolidated statement of operations amounted to a loss of approximately $1.8 million, a gain of approximately $0.4 million and a gain of approximately $0.8 million for the fiscal years ended June 30, 2006, 2007 and 2008, respectively. Furthermore, a 10% appreciation of the U.S. dollar relative to the local currency exchange rates would have resulted in a net increase in our operating income of approximately $8.0 million in fiscal 2008. Conversely, a 10% depreciation of the U.S. dollar relative to the local currency exchange rates would have resulted in a net decrease in our operating income of approximately $8.0 million in fiscal 2008.

Use of Derivatives

We may, from time to time, purchase foreign exchange contracts, in order to attempt to reduce foreign exchange transaction gains and losses, or enter into interest rate swaps. As of June 30, 2006, we had a $25.4 million foreign currency forward contract outstanding to buy U.K. pounds in anticipation of the Del Mar Reynolds acquisition. Transaction gains during the year ended June 30, 2006 included a $0.5 million gain related to this contract. In July 2006, we completed the Del Mar Reynolds acquisition and the foreign currency forward contract settled, resulting in a fiscal 2007 loss of $0.1 million related to this contract. There were no foreign exchange contracts or interest rate swaps outstanding as of June 30, 2007 and June 30, 2008.

Importance of International Markets

International markets provide us with significant growth opportunities. However, the following events, among others, could adversely affect our financial results in subsequent periods: periodic economic downturns in different regions of the world, changes in trade policies or tariffs, civil or military conflict and other political instability. We continue to perform ongoing credit evaluations of our customers’ financial condition and, if deemed necessary, we require advance payments for sales. We monitor economic and currency conditions around the world to evaluate whether there may be any significant effect on our international sales in the future. Due to our overseas investments and the necessity of dealing with local currencies in our foreign business transactions, we are at risk with respect to foreign currency fluctuations.

Inflation

We do not believe that inflation has had a material impact on our results of operations.

Interest Rate Risk

All highly liquid investments with maturity of three months or less are classified as cash equivalents and recorded in the balance sheet at fair value. Short-term investments are comprised of high-quality marketable securities.

CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of June 30, 2008, the end of the period covered by this report, our management, including our Chief Executive Officer and our Chief Financial Officer, reviewed and evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended). Such disclosure controls and procedures are designed to ensure that material information we must disclose in this report is recorded, processed, summarized and filed or submitted on a timely basis. Based upon that evaluation our management, Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of June 30, 2008.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of management, including the Chief Executive Officer and our Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation, management concluded that our internal control over financial reporting was effective as of June 30, 2008.

Moss Adams LLP, an independent registered public accounting firm that audited the financial statements included in this report, has issued its attestation report, which appears below, on our management’s assessment of our internal controls over financial reporting.

Changes in Internal Control over Financial Reporting

During fiscal 2008 we implemented Hyperion Financial Manager (HFM) software to enhance our worldwide consolidation of financial information. This software implementation is part of an ongoing effort to improve the overall efficiency and effectiveness of our financial reporting process. In connection with this implementation, we modified the design, operation and documentation of our internal control processes impacted by the new software.

There were no other changes in our internal control over financial reporting during fiscal 2008 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of OSI Systems, Inc.:

Hawthorne, California

We have audited OSI Systems, Inc. and subsidiaries, (the Company) internal control over financial reporting as of June 30, 2008, based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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 accounting principles generally accepted in the United States of America. 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 consolidated 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.

In our opinion, OSI Systems, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of June 30, 2008, based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule of OSI Systems, Inc. and subsidiaries as of and for the year ended June 30, 2008, and our report dated August 28, 2008 expressed an unqualified opinion on those consolidated financial statements and financial statement schedule.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of OSI Systems, Inc.:

We have audited the accompanying consolidated balance sheets of OSI Systems, Inc. and Subsidiaries as of June 30, 2007 and 2008, and the related consolidated statements of operations, shareholders’ equity and cash flows for the three years ended June 30, 2006, 2007 and 2008. Our audits also included the financial statement schedule listed in the index at Item 15 in Schedule II. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of OSI Systems, Inc. and Subsidiaries as of June 30, 2007 and 2008, and the consolidated results of its operations and cash flows for the years ended June 30, 2006, 2007 and 2008, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

As discussed in Note 14 to the consolidated financial statements, the Company adopted Statement of Financial Accounting Standard No. 158 “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans—an Amendment of FASB Statements No. 87, 88, 106 and 132(R),” which changed the Company’s method of accounting for pension and postretirement benefits as of June 30, 2007. As discussed in Notes 1 and 10 to the consolidated financial statements, effective July 1, 2007, the Company adopted FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes—an Interpretation of FASB No. 109.”

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of OSI Systems, Inc. and Subsidiaries’ internal control over financial reporting as of June 30, 2008, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated August 28, 2008 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Rapiscan Systems products fall into four categories: (a) baggage and parcel inspection, (b) cargo and vehicle inspection, (c) hold (checked) baggage screening and (d) people screening.

Through its Healthcare division, the Company designs, manufactures and markets patient monitoring, diagnostic cardiology and anesthesia systems worldwide to end users, primarily under the “Spacelabs” trade name. These products are used by care providers in critical care, emergency and perioperative areas within hospitals as well as physicians offices, medical clinics and ambulatory surgery centers. The Company’s Healthcare division also offers centralized cardiac safety core laboratory services in connection with clinical trials by or on behalf of pharmaceutical companies and clinical research organizations.

Through its Optoelectronics and Manufacturing division, the Company designs, manufactures and markets optoelectronic devices and value-added manufacturing services worldwide for use in a broad range of applications, including aerospace and defense electronics, security and inspection systems, medical imaging and diagnostics, computed tomography, toll and traffic management systems, fiber optics, telecommunications, weapons simulation systems, gaming, office automation, computer peripherals and industrial automation. The Company sells optoelectronic devices primarily under the “OSI Optoelectronics” trade name and performs value-added manufacturing services primarily under the “OSI Electronics” trade name. This division provides products and services to original equipment manufacturers as well as to the Company’s own Security and Healthcare divisions. The Optoelectronics and Manufacturing division also designs toll and traffic management systems under the “OSI LaserScan” trade name and systems for measuring bone density under the “Osteometer” trade name.

Consolidation—The Consolidated Financial Statements include the accounts of OSI Systems, Inc. and its wholly-owned subsidiaries, and also include the accounts and operating results of Spacelabs Healthcare, OSI Electronics Pte Ltd and Opto Sensors Hong Kong Limited, less that portion of income or loss allocated to minority interest. All significant intercompany accounts and transactions have been eliminated in consolidation.

Spacelabs Healthcare Public Offering and Repurchase—In October 2005, Spacelabs Healthcare, Inc., a subsidiary composed of the business operations of the Company’s Healthcare division, completed an initial public offering of approximately 20% of its total issued and outstanding common stock. The Spacelabs Healthcare shares traded under the ticker symbol “SLAB” on the AIM (formerly known as the Alternative

Investment Market), a stock market administered by the London Stock Exchange. In the second quarter of fiscal 2007, the Company began repurchasing publicly-traded shares of Spacelabs Healthcare, increasing the Company’s ownership to 84% as of June 30, 2007. By December 31, 2007, the Company increased its ownership in Spacelabs Healthcare to 100% by repurchasing all remaining shares of Spacelabs Healthcare. During fiscal 2008, the Company spent approximately $15.8 million in cash and issued 240,000 shares of the Company’s Common Stock in exchange for the remaining outstanding Spacelabs Healthcare shares. At the time of issuance, the 240,000 shares of the Company’s Common Stock had a fair value of $5.9 million. Effective January 24, 2008, the Company cancelled Spacelabs Healthcare’s AIM listing. See Note 6 for additional discussion about the repurchase of the Spacelabs Healthcare shares.

Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the 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. Actual results could differ from those estimates.

Reclassifications—Certain reclassifications have been made to prior year amounts to conform to the current year’s presentation, with no impact on Shareholders’ equity, net income (loss) or net cash flows from operating, investing or financing activities.

Cash Equivalents—The Company considers all highly liquid investments purchased with maturities of three months or less as of the acquisition date, to be cash equivalents.

Allowance for Doubtful Accounts—The allowance for doubtful accounts involves estimates based on management’s judgment, review of individual receivables and analysis of historical bad debts. The Company adjusts customer credit limits based upon each customer’s credit worthiness. The Company monitors collections and payments from its customers and maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

Inventories—Inventories are generally stated at the lower of cost (first-in, first-out) or market. The Company writes down inventory for slow-moving and obsolete inventory based on assessments of future demands, market conditions and customers who may be experiencing financial difficulties. If these factors are less favorable than those projected, additional inventory write-downs may be required. As part of a global review of its operations, the Company assessed the value of certain technologies and product lines. As a result of this assessment, the Company impaired inventory by $10.3 million in fiscal 2007. See Note 7 for additional information about this write-down.

Property and Equipment—Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets. Amortization of leasehold improvements is calculated on the straight-line basis over the shorter of the useful life of the asset or the lease term. Leased capital assets are included in property and equipment. Amortization of property and equipment under capital leases is included with depreciation expense.

Goodwill and Other Intangible Assets and Valuation of Long-Lived Assets—Goodwill represents the excess purchase price of net tangible and intangible assets acquired in business combinations over their estimated fair value. Goodwill is allocated to the Company’s segments based on the nature of the product line of the acquired entity. In accordance with Statement of Financial Accounting Standards No. 141, “Business

F-8

OSI SYSTEMS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE THREE YEARS ENDED JUNE 30, 2008

Combinations” (SFAS 141) and Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (SFAS 142), goodwill is tested for impairment on an annual basis and earlier if there is an indicator of impairment. Furthermore, SFAS 142 requires purchased intangible assets other than goodwill to be amortized over their useful lives unless these lives are determined to be indefinite. For purposes of SFAS 142, the Company has determined that it has four reporting units, consisting of the Security division, the Optoelectronics and Manufacturing division and two reporting units within the Healthcare division. The Company tests goodwill for impairment annually in its second fiscal quarter using a two-step process. First, the Company determines if the carrying amount of any of the reporting units within each of its divisions exceeds its fair value. It uses a discounted cash flows method to make this determination for its Security and Optoelectronics and Manufacturing divisions and it used a market value method for the reporting units within its Healthcare division (based on the market price of Spacelabs Healthcare common stock on the AIM). If these methods indicate a potential impairment of goodwill associated with any reporting unit, the Company then compares the implied fair value of the goodwill associated with the respective reporting unit to its carrying amount to determine if there is an impairment loss. There was no goodwill impairment for fiscal 2006, 2007 and 2008.

In accordance with SFAS No. 144 “Accounting for the Impairment or Disposal of Long-Lived Assets,” (SFAS 144) the Company evaluates long-lived assets, including intangible assets other than goodwill, for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An impairment is considered to exist if the total estimated future cash flows on an undiscounted basis are less than the carrying amount of the assets. If impairment does exist, the Company measures the impairment loss and records it based on the discounted estimate of future cash flows. In estimating future cash flows, the Company groups assets at the lowest level for which there are identifiable cash flows that are largely independent of cash flows from other asset groups. The Company’s estimate of future cash flows is based upon, among other things, certain assumptions about expected future operating performance, growth rates and other factors.

During fiscal 2007, the Company recognized non-cash impairment charges totaling $21.5 million relating to software development costs, core technology, developed technology, customer relationships/backlog and fixed assets. Of the $21.5 million impairment charge, the Company recognized $21.3 million within the Security division and $0.2 million within the Optoelectronics and Manufacturing division. See Note 7 for additional information about these impairment charges. There were no such impairments in fiscal 2006 or 2008.

Income Taxes—Deferred income taxes are provided for temporary differences between the financial statement and income tax basis of the Company’s assets and liabilities, based on enacted tax rates. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred income tax assets will not be realized. On July 1, 2007, the Company adopted Financial Accounting Standards Board (FASB) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (FIN 48). FIN 48 prescribes a two-step process for the financial statement measurement and recognition of a tax position taken or expected to be taken in a tax return. The first step involves the determination of whether it is more likely than not (greater than 50 percent likelihood) that a tax position will be sustained upon examination, based on the technical merits of the position. The second step requires that any tax position that meets the more-likely-than-not recognition threshold be measured and recognized in the financial statements at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. FIN 48 also provides guidance on the accounting for related interest and penalties, financial statement classification and disclosure. The cumulative effect of applying FIN 48 is to be reported as an adjustment to the opening balance of retained earnings in the period of adoption. See Note 10 for additional information regarding the impact of FIN 48.

FOR THE THREE YEARS ENDED JUNE 30, 2008

Fair Value of Financial Instruments—The Company’s financial instruments consist primarily of cash, marketable securities, accounts receivable, accounts payable and debt instruments. The carrying values of financial instruments, other than debt instruments, are representative of their fair values due to their short-term maturities. The carrying values of the Company’s long-term debt instruments are considered to approximate their fair values because the interest rates of these instruments are variable or comparable to current rates offered to the Company.

Derivative Instruments—The Company may, from time to time, purchase foreign exchange contracts in order to attempt to reduce foreign exchange transaction gains and losses, or enter into interest rate swaps. As of June 30, 2006, the Company had a $25.4 million foreign currency forward contract outstanding to buy British pounds in anticipation of the acquisition of Del Mar Reynolds, a global manufacturer and distributor of cardiac monitoring systems. Transaction gains during fiscal 2006 included a $0.5 million gain related to this contract. In July 2006, the Company completed the Del Mar Reynolds acquisition and the foreign currency forward contract settled, resulting in a fiscal 2007 loss of $0.1 million related to this contract. As of June 30, 2008, no such foreign exchange contracts existed.

Revenue Recognition—The Company recognizes revenue upon shipment of products when title and risk of loss passes, and when terms are fixed and collection is probable. In accordance with the terms of Staff Accounting Bulletin No. 104, “Revenue Recognition,” and Emerging Issues Task Force (EITF) Issue No. 00-21, “Revenue Arrangements with Multiple Deliverables,” where installation services, if provided, are essential to the functionality of the equipment, the portion of revenue for the sale attributable to installation is deferred and recognized when the installation service is provided. In an instance where terms of sale include subjective customer acceptance criteria, revenue is deferred until the acceptance criteria are met. Concurrent with the shipment of the product, the Company accrues estimated product return reserves and warranty expenses. Critical judgments made by management related to revenue recognition include the determination of whether or not customer acceptance criteria are perfunctory or inconsequential. The determination of whether or not the customer acceptance terms are perfunctory or inconsequential impacts the amount and timing of revenue recognized. Critical judgments also include estimates of warranty reserves, which are established based on historical experience and knowledge of the product.

The Company undertakes projects that include the design, development and manufacture or fabrication of large complex cargo and vehicle inspection systems that are specially customized to customer’s specifications or that involve fixed site construction. Sales under such contracts are recorded under the percentage-of-completion method in accordance with Statement of Position No. 81-1 “Accounting for Performance of Construction-Type and Certain Production-Type Contracts.” Costs and estimated revenues are recorded as work is performed based on the percentage that incurred costs bear to estimated total costs utilizing the most recent estimates of costs. If the current contract estimate indicates a loss, provision is made for the total anticipated loss in the current period. Critical estimates made by management related to revenue recognition under the percentage-of-completion method include the estimation of costs at completion and the determination of the overall margin rate on the specific project. As of June 30, 2007, provisions for anticipated losses in contracts amounting to $0.8 million were recorded. As of June 30, 2006 and 2008, no such provisions were recorded.

Revenues from separate service maintenance contracts are recognized ratably over the term of the agreements. For other services, service revenues are recognized as the services are performed. Deferred revenue for services arises from advance payments received from customers for services not yet performed.

Freight—The Company records shipping and handling fees it charges to its customers as revenue and related costs as cost of goods sold.

FOR THE THREE YEARS ENDED JUNE 30, 2008

Research and Development Costs—Research and development costs are those costs related to the development of a new product, process or service, or significant improvement to an existing product, process or service. Such costs are charged to operations as incurred. Grants for research and development are recorded as revenue in the period earned, and the related costs are classified in cost of goods sold.

Stock-Based Compensation—Effective July 1, 2005, the Company adopted the provisions of Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment” (SFAS 123R) using the modified-prospective-transition method. Under this method, share-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as expense over the employee’s requisite service period for all share-based awards granted, modified or cancelled as of July 1, 2005. Prior to July 1, 2005, the Company accounted for its share-based awards under the recognition and measurement principles of APB 25 “Accounting for Stock issued to Employees” (APB 25) and its related interpretations and adopted the disclosure only provision of SFAS 123, “Accounting for Stock-Based Compensation” (SFAS 123). Accordingly, for fiscal years ending prior to July 1, 2005, no compensation cost was recognized for the employee stock option plan or employee stock purchase plan under the fair value recognition provisions of SFAS 123. See Employee Stock Plans at Note 9 to the Consolidated Financial Statements.

Restructuring charges—The Company periodically consolidates processes and facilities of its subsidiaries. The Company records the associated charges as restructuring charges and calculates them in the Consolidated Financial Statements in accordance with SFAS 144, and SFAS No. 146, “Accounting for Exit or Disposal Activities.” In fiscal 2006, 2007 and 2008, the Company consolidated manufacturing processes and facilities of certain businesses resulting in pre-tax restructuring charges of $0.8 million, $4.5 million and $4.7 million, respectively. See Note 7 for additional information about these restructuring charges.

Concentrations of Credit Risk—Financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash, cash equivalents, marketable securities and accounts receivable. The Company restricts investments in cash equivalents to financial institutions with high credit standing. Credit risk on accounts receivable is minimized as a result of the large and diverse nature of the Company’s worldwide customer base. No individual customer accounted for more than 10% of accounts receivable as of June 30, 2007 or 2008 or revenues for the years ended June 30, 2006, 2007 or 2008. The Company performs ongoing credit evaluations of its customers’ financial condition and maintains allowances for potential credit losses. For cost, control and efficiency reasons, the Company at times purchases raw materials and subcomponents from a single vendor though it generally qualifies second sources for most of its raw materials and critical components or has identified alternative sources of supply.

Foreign Currency Translation—The Company transacts business in various foreign currencies. In general, the functional currency of a foreign operation is the local country’s currency. Consequently, revenues and expenses of operations outside the United States are translated into United States dollars using average exchange rates while assets and liabilities of operations outside the United States are translated into United States dollars using year-end exchange rates. The effects of foreign currency translation adjustments are included in stockholders’ equity as a component of accumulated other comprehensive income (AOCI) in the accompanying consolidated balance sheets. Transaction gains (losses) of approximately ($1.8) million, $0.4 million and $0.8 million, were included in the consolidated statement of operations for fiscal 2006, 2007 and 2008, respectively.

Earnings (Loss) per Share—Basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common shareholders by the sum of the weighted average number of common and dilutive potential common shares outstanding. Potential common shares consist of the shares issuable upon the exercise of stock options or warrants under the treasury stock method.

Diluted earnings (loss) per share	$	(0.17	)	$	(1.12	)	$	0.78

As of June 30, 2006, 2007 and 2008, approximately 3.0 million, 2.6 million and 0.4 million, respectively, of potentially dilutive shares associated with stock options and stock warrants, collectively, were not included in diluted earnings per common share calculations because to do so would have been antidilutive.

Provision for Warranties—The Company offers its customers warranties on most products sold to them. These warranties typically provide for repairs and maintenance for a specified time period. Concurrent with the sale of products, a provision for estimated warranty expenses is recorded with a corresponding increase in cost of goods sold. This provision is adjusted periodically based on historical and anticipated experience. Actual expenses of repairs under warranty, including parts and labor, are charged to this provision when incurred.

New Accounting Pronouncements—In September 2006, FASB issued SFAS No. 157, “Fair Value Measurements.” This statement defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. It is effective for fiscal years beginning after November 15, 2007. The Company has not yet determined the impact that this statement will have on its Consolidated Financial Statements.

F-12

OSI SYSTEMS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

FOR THE THREE YEARS ENDED JUNE 30, 2008

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities - including an amendment of SFAS No. 115,” (SFAS 159). SFAS 159 allows companies to elect to measure many financial assets and financial liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been chosen are reported in earnings. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company has not yet determined the impact, if any, that this statement will have on its Consolidated Financial Statements.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements, an amendment of ARB No. 51” (SFAS 160). The new standard changes the accounting and reporting of noncontrolling interests, which have historically been referred to as minority interests. SFAS 160 requires that noncontrolling interests be presented in the consolidated balance sheets within shareholders’ equity, but separate from the parent’s equity, and that the amount of consolidated net income attributable to the parent and to the noncontrolling interest be clearly identified and presented in the consolidated statements of income. Any losses in excess of the noncontrolling interest’s equity interest will continue to be allocated to the noncontrolling interest. Purchases or sales of equity interests that do not result in a change of control will be accounted for as equity transactions. Upon a loss of control, the interest sold, as well as any interest retained, will be measured at fair value, with any gain or loss recognized in earnings. In partial acquisitions, when control is obtained, the acquiring company will recognize at fair value, 100% of the assets and liabilities, including goodwill, as if the entire target company had been acquired. SFAS 160 is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008, with early adoption prohibited. The new standard will be applied prospectively, except for the presentation and disclosure requirements, which will be applied retrospectively for all periods presented. The Company has not yet determined the impact, if any, that this statement will have on its Consolidated Financial Statements and will adopt the standard at the beginning of fiscal 2010.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), “Business Combinations” (SFAS 141(R)). The new standard changes the accounting for business combinations in a number of significant respects. The key changes include the expansion of transactions that will qualify as business combinations, the capitalization of in-process research and development (IPR&D) as an indefinite-lived asset, the recognition of certain acquired contingent assets and liabilities at fair value, the expensing of acquisition costs, the expensing of costs associated with restructuring the acquired company, the recognition of contingent consideration at fair value on the acquisition date, and the recognition of post-acquisition date changes in deferred tax asset valuation allowances and acquired income tax uncertainties as income tax expense or benefit. SFAS 141(R) is effective for business combinations that close in years beginning on or after December 15, 2008, with early adoption prohibited. The Company has not yet determined the impact, if any, that this statement will have on its Consolidated Financial Statements and will adopt the standard at the beginning of fiscal 2010.

In May 2008, the FASB issued SFAS No. 162, “Hierarchy of Generally Accepted Accounting Principles” (SFAS 162). This statement is intended to improve financial reporting by identifying a consistent framework, or hierarchy, for selecting accounting principles to be used in preparing financial statements of nongovernmental entities that are presented in conformity with GAAP. This statement will be effective 60 days following the U.S. Securities and Exchange Commission’s approval of the Public Company Accounting Oversight Board amendment to AU Section 411, “The Meaning of Present Fairly in Conformity with Generally Accepted Accounting Principles.” The Company believes that SFAS 162 will have no effect on our financial statements.

2. BUSINESS COMBINATIONS

Del Mar Reynolds Acquisition—In July 2006, the Company’s Healthcare division completed the acquisition of the Del Mar Reynolds cardiology division of Ferraris Group PLC. This acquisition expands the portfolio of products that the Company’s Healthcare division offers to the hospital market with the addition of cardiac monitoring systems. Del Mar Reynolds also maintained a core laboratory business that provides clinical trial services to pharmaceutical companies and to clinical research organizations.

Pursuant to the terms of the acquisition agreement, the Company’s Healthcare division made an initial cash payment of $25.9 million, subject to a working capital adjustment and to an adjustment of plus or minus $1.9 million based upon revenue and earnings results for Del Mar Reynolds for the 13-month period ending September 30, 2006. In September 2006, Ferraris Group PLC paid back $1.7 million in connection with a purchase price adjustment related to working capital and in November 2006, it paid an additional $1.9 million as a result of the failure of Del Mar Reynolds to meet certain revenue and earnings results for the 13-month period ending September 30, 2006.

The results of operations for Del Mar Reynolds have been included in the Consolidated Financial Statements as of the date of acquisition. The total cost of the acquisition was as follows (in thousands):


Cash paid for Common Stock, net of cash acquired	$	24,911
Less refund pursuant to working capital adjustment		(1,694	)
Less receivable pursuant to 13-month revenue and earnings adjustment		(1,872	)
Direct costs		794

Total purchase price	$	22,139

The final purchase price allocation was as follows (in thousands):


In-process research and development costs acquired	$	561
Identifiable intangible assets acquired		7,567
Goodwill		17,208
Net liabilities acquired		(3,197	)

	$	22,139

A history of operating margins and profitability, a strong scientific employee base and operations in an attractive market niche were among the factors that contributed to a purchase price resulting in the recognition of goodwill. In-process research and development costs acquired were expensed during fiscal 2007, and are included in research and development costs. Projects that qualify as in-process research and development represent those that have not yet reached technological feasibility and which have no alternative future use.

During fiscal 2007 and 2008, the Company paid $1.2 million and $1.4 million, respectively, in connection with severance charges, relocation costs and rent obligations as part of the integration of these business operations. As of June 30, 2007, the Company had accrued $2.4 million for additional payments of such amounts. These amounts are included in accrued expenses and other current liabilities in the Consolidated Balance Sheets. As of June 30, 2008, no accrual remains on the books of the Company related to such charges.

During fiscal 2007, the Company completed another acquisition that was not material to the overall Consolidated Financial Statements and the results of the operations have been included in the accompanying Consolidated Financial Statements from the date of the acquisition.

The acquisition price was approximately $47.9 million in cash (net of cash acquired), including acquisition costs. In March 2007, the Company settled a dispute regarding the purchase and received $15 million. The receipt of this amount has been recorded as Other Income in the Consolidated Statement of Operations for fiscal 2007.

Amortization expense for the fiscal 2006, 2007 and 2008 was $3.6 million, $4.2 million and $3.7 million, respectively. Future acquisitions could cause these amounts to increase. In addition, if impairment events occur, they could accelerate the timing of purchased intangible asset charges. At June 30, 2008, estimated future amortization expense was as follows (in thousands):

Software development costs for software products to be licensed to others, incurred before establishing technological feasibility, are charged to operations. Software development costs incurred after establishing technological feasibility and purchased software costs are capitalized on a product-by-product basis until the product is available for general release to customers at which time amortization begins. Annual amortization, charged to cost of sales, is the greater of: (i) the amount computed using the ratio that current gross revenues for a product bear to the total current and anticipated future gross revenues for that product or (ii) the straight-line method over the remaining estimated economic life of the product. During fiscal 2006, 2007 and 2008, the Company capitalized software development costs in the amount of $0.2 million, $0.4 million and $1.9 million, respectively.

7. IMPAIRMENT, RESTRUCTURING AND OTHER CHARGES

During fiscal 2007, the Company conducted a global review of its operations. This review included assessments of the Company’s product lines and their economic viability, resulting in management’s decision to discontinue several products. As a result, identifiable intangible and fixed assets related to these products were tested for impairment and were deemed to be permanently impaired, whereby the Company recorded impairment charges of $21.5 million. Further, it was determined that the abandonment of certain product lines required that $10.3 of inventory charges be recorded to reduce inventory levels to the lower of cost or market. Of the $21.5 million of impairment charges, $21.3 million was recorded within the Company’s Security division and $0.2 million was recorded within the Optoelectronics and Manufacturing division. Of the $10.3 million of inventory charges, $9.9 million was recorded within the Company’s Security division and $0.4 million was recorded within the Optoelectronics and Manufacturing division. Such inventory charges are reflected in cost of goods sold in the condensed Consolidated Financial Statements. Asset impairments were calculated in accordance with SFAS 144 as discussed in Note 1.

The following table summarizes the impairment, restructuring and other charges (in thousands):

8. LINE-OF-CREDIT BORROWINGS AND DEBT

In July, 2007, the Company entered into a credit agreement with certain lenders. The agreement provided for an $89.5 million credit facility, which was subsequently increased to $124.5 million in June 2008. The new credit agreement replaced former U.S. dollar credit agreements, which were repaid and terminated simultaneously with the close of the new agreement. The new credit agreement consists of a $74.5 million five-year revolving credit facility, including a $45 million sub-limit for letters-of-credit, and a $50 million five-year term loan. Borrowings under this facility bear interest at either (a) the U.S. dollar-based London Interbank Offered Rate (LIBOR) plus between 2.00% and 2.50% or (b) the bank’s prime rate plus between 1.00% and 1.50%. The rates are determined based on the Company’s consolidated leverage ratio. As of June 30, 2008, the effective weighted average interest rate under the credit agreement was 5.0% per annum. Borrowings under the credit agreement are guaranteed by substantially all of the direct and indirect wholly-owned subsidiaries of the Company and are secured by substantially all of its assets and by the assets of its subsidiaries. The agreement contains various representations, warranties, affirmative, negative and financial covenants, and conditions of default customary for financing agreements of this type. As of June 30, 2008, $47.8 million was outstanding under the term loan, $14.0 million was outstanding under the revolving credit facility, and $3.6 million was outstanding under the letter-of-credit facility.

Several of the Company’s foreign subsidiaries maintain bank lines-of-credit, denominated in local currencies, to meet short-term working capital requirements and for the issuance of letters-of-credit. As of June 30, 2008, the total amount available under these various credit facilities was $34.8 million with a total cash borrowing sub-limit of $8.7 million, of which $4.7 million was outstanding at June 30, 2008. The weighted average interest rate of these facilities was 7.1% per annum at June 30, 2008.

9. STOCK-BASED COMPENSATION

As of June 30, 2008, the Company maintained one significant stock-based compensation plan – the 2006 Equity Participation Plan of OSI Systems (OSI Plan). The OSI Plan allows for the issuance of restricted stock and the granting of stock options. As of June 30, 2007 the Company had maintained three significant plans: (a) the OSI Plan, (b) the 2005 Equity Participation Plan of Spacelabs Healthcare (Spacelabs Plan) and (c) the 2006 Equity Participation Plan of Rapiscan Systems Holdings, Inc. (Rapiscan Plan). However, during fiscal 2008, the Company converted all of the options outstanding under the Spacelabs Plan and Rapiscan Plan into options under the OSI Plan. Specifically, all outstanding Spacelabs Options were converted in December 2007 and all Rapiscan Options were converted in March 2008. The methodology used for such conversions provided equivalent fair values under the OSI Plan. Therefore, no additional compensation expense was incurred by the Company as a result of these conversions. As of June 30, 2008, there were no outstanding options under either the Spacelabs Plan or the Rapiscan Plan.

Stock based compensation expense, net of estimated taxes	$	4,089	$	3,879	$	3,273

As of June 30, 2008, total unrecognized compensation cost related to non-vested share-based compensation arrangements granted amounted to $3.4 million for stock options and $3.3 million for restricted stock under the OSI Plan. The Company expects to recognize these costs over a weighted-average period of 1.6 years with respect to the options and 3.4 years for grants of restricted stock.

Employee Stock Purchase Plan—The Company has an employee stock purchase plan under which eligible employees may purchase a limited number of shares of Common Stock at a discount of up to 15% of the market value of such stock at pre-determined, plan-defined dates. During the three years ended June 30, 2006, 2007 and 2008, employees purchased 74,250, 77,471 and 65,908 shares, respectively. As of June 30, 2008, there were 133,067 shares of the Company’s Common Stock available for issuance under the plan.

Stock Option Plans

OSI Plan—Under the OSI Plan, the Company is authorized to grant up to 5,350,000 shares of Common Stock in the form of incentive options, nonqualified options or restricted stock. Under the plan, the exercise price of nonqualified options may not be less than 85% of the fair market value of the Company’s Common Stock on the date of grant. The exercise price of incentive stock options may not be less than the fair market value of the Company’s Common Stock at the date of grant. The exercise price of incentive stock options granted to individuals who own more than 10% of the Company’s voting stock may not be less than 110% of the fair market value of the Company’s Common Stock on the date of grant.

Staff Accounting Bulletin No. 110 (SAB 110) provides the views of the Securities and Exchange Commission regarding valuation of share-based payments pursuant to SFAS 123(R). With respect to volatility, SAB 110 clarifies that no single method of estimating volatility is proper under all circumstances and that to the extent a company can derive implied volatility based on the trading of its financial instruments on a public market, it may be appropriate to use both implied and historical volatility in its assumptions. The Company has certain financial instruments that are publicly traded from which the Company can derive the implied volatility. Therefore, the Company used implied and historical volatility for valuing its stock options. The Company believes that implied and historical volatility is a better indicator of expected volatility because it is generally reflective of both historical volatility and expectations of how future volatility will differ from historical volatility.

As of June 30, 2008, there were 1,062,004 shares available for grant under the OSI Plan. Under the terms of the OSI Plan, no more than 797,050 of these shares may be granted in the form of restricted stock.

Spacelabs Plan—The Company established the Spacelabs Plan in October 2005, under which it authorized the grant of up to 10,000,000 shares of Spacelabs Healthcare common stock.

The Company estimated the fair value of each option award as of the date of grant using a Black-Scholes option pricing model that used assumptions detailed in the table below. The Company based expected volatilities on the historical volatilities of the publicly traded common stock of a select peer group of companies that are similar to Spacelabs Healthcare. The Company determined the expected term assumption under the “Simplified Method,” as defined in SAB 107, as it lacks historical data and is unable to make reasonable expectations regarding future exercise patterns. The risk-free rate was based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option.

The Company determined the fair value of the options issued during the year ended June 30, 2006, 2007 and 2008 on the date of the grant using the Black-Scholes option pricing model with the following weighted average assumptions:

10. INCOME TAXES

On July 1, 2007, the Company adopted FIN 48. The cumulative effect of applying FIN 48 to the Company has been recorded as a decrease of $3.3 million to retained earnings, an increase of $2.4 million to deferred tax asset and an increase of $6.2 million to deferred tax liability.

As of July 1, 2007 and June 30, 2008, the total amount of gross unrecognized tax benefits was $6.2 million and $6.5 million, respectively. Of this total, $2.7 million represents the amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate. The Company recognizes potential interest and penalties related to income tax matters in income tax expense. As of June 30, 2008, the Company has $1.4 million accrued for the payment of interest and penalties.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands).

The Company conducts business globally and, as a result, one or more of the Company’s subsidiaries file income tax returns in the U.S. federal jurisdiction and multiple states, local and foreign jurisdictions. The Company is no longer subject to U.S. federal IRS audit for years prior to 2004. With limited exception, the Company’s operations in state and foreign tax jurisdictions are no longer subject to audit by the respective tax authorities for tax years prior to 1998.

The Company does not provide for U.S. income taxes on the undistributed earnings of its foreign subsidiaries as it is the Company’s intention to utilize those earnings in the foreign operations for an indefinite period of time. At June 30, 2008, undistributed earnings of the foreign subsidiaries amounted to approximately $42 million. It is not practical to determine the amount of income or withholding tax that would be payable upon the remittance of these earnings.

In fiscal 2006, the Company realized a gain in the amount of $18.7 million from the sale of a 20% interest in Spacelabs Healthcare. For income tax purposes, the gain was deferred under provisions of the Internal Revenue Code and the regulations thereunder. At the time, the Company could not determine conclusively that the deferral would be indefinite under SFAS No. 109, “Accounting for Income Taxes” (SFAS 109) and, accordingly, the Company recorded a deferred tax liability in the amount of $4.0 million. Thereafter, the Company continued to assess its interest in Spacelabs Healthcare and whether the deferred gain would be recognized for tax purposes, but did not determine conclusively that the deferral would be indefinite. As a result, the Company adjusted the deferred tax liability for subsequent book/tax basis differences in its remaining interest in Spacelabs Healthcare for periods subsequent to the disposition. As of December 31, 2007, the deferred tax liability was $4.3 million, which represented the original deferred tax gain plus subsequent book/tax basis differences in the Company’s remaining interest in Spacelabs Healthcare. However, following the repurchase of all outstanding shares of Spacelabs Healthcare (see Note 1), and other operating factors, the Company reconsidered its investment holding strategy for Spacelabs Healthcare and concluded that the original gain plus subsequent book/tax basis adjustments in the Company’s interest in Spacelabs Healthcare will be deferred indefinitely under SFAS 109 and in accordance with the Internal Revenue Code and the regulations thereunder. Accordingly, the deferred tax liability is no longer required, resulting in a benefit to the deferred tax provision of $4.3 million during fiscal 2008.

The Company’s federal net operating losses will begin to expire in the tax year ending June 30, 2018, and are subject to limitations on their utilization. As of June 30, 2008, the Company had state tax credit carry forwards, including research and development and revitalization zone credits, of approximately $2.3 million. As of June 30, 2008, the Company had no federal tax credit carry forwards. The Company’s state tax credit carry forwards will begin to expire in the tax year ending June 30, 2011.

The Company has established a valuation allowance in accordance with the provisions of SFAS No. 109, “Accounting For Income Taxes.” The valuation allowance relates to the net operating loss of foreign subsidiaries, net operating loss subject to Separate Return Limitation Year rules, an unrealized capital loss related to a write-down of an equity investment and revitalization zone credits. The Company reviews the adequacy of valuation allowances and releases the allowances when it is determined that it is more likely than not that the benefits will be realized.

	Payments Due by Period
	Total		Less than 1 year		2-3 years		4-5 years		After 5 years
Total debt (excluding capital lease obligations)	$	53,491	$	5,753	$	18,286	$	25,894	$	3,558

Operating Leases—The Company leases facilities and certain equipment under various operating lease agreements. Certain leases provide for periodic rent increases and may contain escalation clauses and renewal options. Rent expense totaled $9.7 million, $11.6 million and $10.0 million for fiscal years 2006, 2007 and 2008, respectively.

In October 2004, the Company amended two real property leases covering office and manufacturing facilities in Issaquah, Washington. Under the amendments, the Company extended the term of such leases by approximately two years and relinquished certain options it held to terminate portions of such leases early. As a result, the leases expire in 2014. In consideration, the landlord paid the Company $2.0 million in cash which has been recorded as deferred rent and is being amortized over the remaining term of the lease. The leases are accounted for as operating leases.

Commitments—Under the terms and conditions of the purchase agreements associated with the following acquisitions, the Company may be obligated to make additional payments.

In August 2002, the Company purchased a minority equity interest in CXR, a U.K.-based research and development company that develops real time tomography systems. In June 2004, the Company increased its equity interest in CXR to approximately 75% and in December 2004 the Company acquired the remaining 25%. As compensation to the selling shareholders for this remaining interest the Company has agreed to make certain royalty payments based on sales of CXR’s products. As of June 30, 2008, no royalty payments have been earned or paid.

In January 2004, the Company completed the acquisition of ARACOR (since renamed Rapiscan Laboratories). During the seven years following the acquisition, contingent consideration of up to $30 million is payable based on its net revenues of certain products and services, provided certain requirements are met. As of June 30, 2008, no contingent consideration has been earned or paid.

In July 2006, the Company completed another acquisition that was not material to the overall Consolidated Financial Statements. The Company paid $0.3 million as an earn-out in fiscal 2008 and expects to make another $0.3 million payment in fiscal 2009 as a final contingent consideration payment.

Environmental Contingencies—The Company is subject to various federal, state and local environmental laws, ordinances and regulations relating to the use, storage, handling and disposal of certain hazardous substances and wastes used or generated in the manufacturing and assembly of the Company’s products. Under such laws, the Company may become liable for the costs of removal or remediation of certain hazardous substances that have been released on or in its facilities or that have been disposed of off-site as waste. Such laws may impose liability without regard to whether the Company knew of or caused the release of such hazardous substances. The Company has conducted Phase I environmental site assessments for each of its properties in the United States at which the Company manufactures products. The purpose of each such report is to identify, as of the date of such report, potential sources of contamination of the property from past and present activities or from nearby operations. In certain cases, the Company has conducted further environmental assessments consisting of soil and groundwater testing and other investigations deemed appropriate by independent environmental consultants. The Company believes that it is currently in compliance with all material environmental regulations in connection with its manufacturing operations, and that it has obtained all material environmental permits necessary to conduct business.

During one investigation, the Company discovered soil and groundwater contamination at its Hawthorne, California facility. The Company filed the requisite reports concerning this problem with the appropriate environmental authorities in fiscal 2001. The Company has not yet received any response to such reports, and no agency action or litigation is presently pending or threatened. The Company also has notified the prior owners of the facility and the present owners and tenants of adjacent properties concerning the problem and has requested from such parties agreements to toll of the statute of limitations with respect to actions against such parties with respect to the contamination in order that the Company may focus its attention on resolution of the contamination problem. The Company’s site was previously used for semiconductor manufacturing similar to that presently conducted on the site by the Company, and it is not presently known who is responsible for the contamination and the remediation. The groundwater contamination is a known regional problem, not limited to the Company’s premises or its immediate surroundings.

The Company has also been informed of soil and groundwater remediation efforts at a facility that its Ferson Technologies subsidiary previously leased in Ocean Springs, Mississippi. Ferson Technologies occupied the facility until October 2003. The Company believes that the owner and previous occupants of the facility have primary responsibility for such remediation and have an agreement with the facility’s owner under which the

F-30

FOR THE THREE YEARS ENDED JUNE 30, 2008

owner is responsible for remediation of pre-existing conditions. However, the Company is unable at this time to ascertain whether Ferson Technologies bears any exposure for remediation costs under applicable environmental regulations. In accordance with SFAS No. 5, “Accounting for Contingencies,” the Company has not accrued for loss contingencies relating to the above environmental matters because it believes that, although unfavorable outcomes may be possible, they are not considered by management to be probable or reasonably estimable. If one or more of these matters is resolved in a manner adverse to the Company, the impact on the Company’s results of operations, financial position and/or liquidity could be material.

Legal Proceedings—In November 2002, L-3 Communications Corporation brought suit against the Company in the District Court for the Southern District of New York seeking a declaratory judgment that L-3 Communications Corporation had not breached its obligations to us concerning the acquisition of PerkinElmer’s Security Detection Systems Business. The Company asserted counterclaims against L-3 Communications Corporation for, among other things, fraud and breach of fiduciary duty. In May 2006, the jury in the case returned a verdict in the Company’s favor and awarded the Company $125 million in damages. The jury found that L-3 Communications Corporation had breached its fiduciary duty to the Company and had committed fraud. The jury awarded the Company $33 million in compensatory damages and $92 million in punitive damages. In addition, the jury also found that the Company had breached a confidentiality agreement and awarded L-3 Communications Corporation nominal damages of one dollar. On June 27, 2008, the United States Court of Appeals for the Second Circuit issued a summary order reversing in part, and vacating in part, the judgment of the district court, and remanding the case to the district court for further proceedings. The Second Circuit held that L-3 did not owe the Company a fiduciary duty as a matter of law and reversed the judgment of the district court on our claims for breach of fiduciary duty and constructive fraud. The Second Circuit vacated the judgment of the district court on the Company’s claim for actual fraud, and remanded that claim to the district court for further proceedings.

The Company is also involved in various other claims and legal proceedings arising out of the ordinary course of business. In the Company’s opinion after consultation with legal counsel, the ultimate disposition of such proceedings will not have a material adverse effect on its financial position, future results of operations, or cash flows. In accordance with SFAS No. 5, “Accounting for Contingencies,” the Company has not accrued for loss contingencies relating to such matters because the Company believes that, although unfavorable outcomes in the proceedings may be possible, they are not considered by management to be probable or reasonably estimable. If one or more of these matters are resolved in a manner adverse to the Company, the impact on the Company’s results of operations, financial position and/or liquidity could be material.

12. SHAREHOLDERS’ EQUITY

Stock Repurchase Program

The Company’s Board of Directors has authorized a series of Common Stock repurchase programs. During fiscal 2006, 2007 and 2008, no shares were repurchased under these programs. At June 30, 2008, 1,330,973 shares were available for repurchase under the stock repurchase programs. The Company generally retires the treasury shares as they are repurchased and records the repurchase as a reduction in common shares in the accompanying Consolidated Financial Statements.

Warrants

In December 2001, the Company issued and sold an aggregate of 2,070,000 shares of Common Stock in a private placement to institutional investors and received net proceeds of $38.3 million. As part of the transaction,

In October 2002, the Company issued and sold an aggregate of 1,250,000 shares of Common Stock in a private placement to institutional investors and received net proceeds of $20.5 million. As part of the transaction, the Company issued warrants to purchase 281,250 additional shares of the Company’s Common Stock at an exercise price of $21.22 per share exercisable at any time, in full or part, no later than October 21, 2009.

In June 2004, the Company issued and sold an aggregate of 1,500,000 shares of Common Stock in a private placement to institutional investors and received net proceeds of $31 million. As part of the transaction, the Company issued warrants to purchase 337,500 additional shares of the Company’s Common Stock at an exercise price of $27.73 per share exercisable at any time, in full or part, no later than June 1, 2011.

During fiscal 2006, 84,847 warrants were exercised resulting in net proceeds to the Company of approximately $1.3 million. During fiscal 2007 and 2008, respectively, no warrants were exercised.

The following summarizes the warrants outstanding as of June 30, 2008:


Exercise Prices	Warrants Outstanding	Remaining Contractual Life (Years)
$23.47	621,000	0.45
$21.22	281,250	1.31
$27.73	337,500	2.92

13. Related-Party Transactions

In 1994, the Company, together with an unrelated company, formed ECIL-Rapiscan Security Products Limited, a joint venture organized under the laws of India. The Company owns a 36% interest in the joint venture, the Company’s Chairman and Chief Executive Officer owns a 10.5% interest, and the Company’s Executive Vice President and President of the Company’s Security division owns a 4.5% ownership interest. The Company’s initial investment was approximately $0.1 million. For the years ended June 30, 2006, 2007 and 2008, the Company’s equity earnings in the joint venture were approximately to $0.4 million, $0.3 million and $0.4 million, respectively. The Company, its Chairman and Chief Executive Officer and the Company’s Executive Vice President and President of the Company’s Security division collectively control less than 50% of the board of directors voting power in the joint venture. As a result, the Company accounts for the investment under the equity method of accounting. The joint venture was formed for the purpose of the manufacture, assembly, service and testing of security and inspection systems and other products. Some of the Company’s subsidiaries are suppliers to the joint venture partner, which in turn manufactures and sells the resulting products. Sales to the joint venture partner for fiscal 2006, 2007, and 2008 were approximately $0.1 million, $0.5 million and $1.6 million, respectively.

The Company has contracted with entities owned by members of its Board of Directors and/or their families to provide messenger service, auto rental and printing services. Such expenses for 2006, 2007 and 2008 were approximately $60,000, $50,000 and $54,000 for messenger services and auto rental and $80,000, $50,000 and $42,000 for printing services, respectively.

14. Employee Benefit Plans

The Company has various qualified employee retirement savings plans. Participants can contribute certain amounts to the plans and the Company matches a certain portion of employee contributions. The Company contributed approximately $1.6 million, $1.9 million and $2.3 million to the plans for the fiscal years ended June 30, 2006, 2007 and 2008, respectively.

The Company sponsors a number of qualified and nonqualified pension plans for its employees. The Company adopted SFAS No. 158 “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans” (SFAS 158) on June 30, 2007. SFAS 158 requires companies to fully recognize the overfunded or underfunded status of each of its defined benefit plan as an asset or liability in the consolidated balance sheet. The asset or liability equals the difference between the fair value of the plan’s assets and its benefit obligation. SFAS 158 has had no impact on the amount of expense recognized in the consolidated statement of income.

SFAS 158 was required to be adopted on a prospective basis. The adoption of SFAS 158 was recorded as an adjustment to assets and liabilities to reflect the plans’ funded status (rather than a prepaid asset or accrued liability), with a corresponding decrease in AOCI, which is a component of shareholders’ equity. The net-of-tax decrease in AOCI at June 30, 2007 relating to the adoption of SFAS 158 was $1.6 million. The impact of adoption of SFAS 158 on individual line items in the Company’s consolidated balance sheet at June 30, 2007 (including related deferred tax balances) was a decrease in the short-term deferred income tax asset of $0.2 million and an increase in other long-term liabilities of $1.8 million. The net total after-tax decrease in AOCI in fiscal 2007 relating to defined benefit pension plans was $0.9 million.

Each year, unrecognized amounts included in AOCI are reclassified from AOCI to retained earnings as the amounts are recognized in the consolidated income statement pursuant to SFAS No. 87, “Employers’ Accounting for Pensions,” SFAS No. 88, “Employers’ Accounting for Settlements and Curtailments of Defined Benefit Pension Plans and for Termination Benefits,” and SFAS No. 106, “Employers’ Accounting for Postretirement Benefits Other Than Pensions.”

As required by SFAS 158, the liabilities associated with underfunded plans are classified as noncurrent, except to the extent the fair value of the plan’s assets is less than the plan’s estimated benefit payments over the next 12 months. In conjunction with the adoption of SFAS 158 on June 30, 2007, the Company made the required current and noncurrent reclassifications in its consolidated balance sheet.

The Company uses a June 30 measurement date for its pension plans.

Weighted average assumptions at year-end:
Discount rate	5.4	%	5.9	%
Expected return on plan assets	6.4	%	6.3	%
Rate of compensation increase	3.8	%	2.9	%

The long term return on assets has been derived from the weighted average of assumed returns on each of the major asset categories. The weighted average is based on the actual proportion of each major asset class held, rather than a benchmark portfolio of assets. The expected returns for each major asset class have been derived from a combination of both historical market returns and current market data as well as the views of a range of investment managers.

Plan Assets and Investment Policy


	Fiscal year ended June 30, 2007				Fiscal year ended June 30, 2008
	Proportion of Fair Value		Expected Rate of Return		Proportion of Fair Value		Expected Rate of Return

Other	9	%	5	%	19	%	5	%

Combined	100.0	%	6.4	%	100	%	6.3	%

The defined benefit plans’ assets are invested in a range of pooled investment funds that provide access to a diverse range of asset classes. The investment objective is to maximize the investment return over the long term without exposing the fund to an unnecessary level of risk. Within this objective, it is recognized that benefits will be secured by the purchase of annuities at the time of employee retirement.

The benchmark is to hold assets broadly in the proportion of 50% equity securities and 50% debt securities. This proportion is allowed to fluctuate with market movements and is not formally rebalanced. The equity holdings are maintained in balanced funds under the control of investment managers.

Day-to-day equities selection decisions are delegated to investment managers, although these are monitored against performance and risk targets. Due to the nature of the pooled funds, there are no significant holdings in any single company (greater than 5% of the total assets). The investment strategy is reviewed on a regular basis, based on the results of the liability studies.
