Industry Background

Telecommunications networks are evolving to support the demand for mobile and high-bandwidth applications such as mobile video services, Internet Protocol video services, or IP-video, peer-to-peer networking, and content-rich, transactional websites. The growth in these applications and services is driving the need for additional bandwidth capacity in many portions of the world's networks. To meet this demand, our customers are upgrading their networks with new optical communications systems and products to increase capacity and increase efficiency with an increased focus on lower total cost of access and transport.

Our products and services address the carrier Ethernet and wavelength division multiplexing, or WDM, optical transport markets, which could provide new opportunities for growth as businesses migrate to Ethernet from legacy technologies such as frame relay, and Digital Subscriber Line, or DSL. Ethernet is the predominant technology in Local Area Networks, or LANs. Metro Ethernet refers to a network based on the Ethernet standard, which covers a metropolitan area and is a common way for telecommunications service providers to connect subscribers and businesses to the Internet. Ethernet networks are deployed by telecommunications service providers because of the lower cost of ownership and the ability to offer high bandwidth with solid reliability. We are building upon over 20 years of optical innovation and 10 years of experience in carrier-class Metro Ethernet as we participate in the next phase of Ethernet

services growth.

We believe the long-term growth of Metro Ethernet and the demand for our optical products will be fueled by the ever-increasing demand for more bandwidth capacity and higher connection speeds. We also believe that growth will occur as telecommunication service providers strive to increase the efficiency and performance of their networks while reducing overall costs. There are several factors driving this growth:


•	High bandwidth applications running over service provider networks require greater network capacity.


•	Residential consumers are increasingly using data intensive applications such as interactive gaming, IPTV, video on demand, video downloads, video-rich content, social networking, and user-generated content such as peer-to-peer file sharing.


•	Business demand is growing due to the increase in applications and data shared across the enterprise, content-rich websites, the growing adoption of software-as-a-service, and IP-based voice and video communications such as video conferencing and VoIP services.


•	Mobile communications continue to grow, while smart phones and other handheld devices are becoming more advanced with bandwidth-intensive applications.

On January 19, 2011, market research firm ComScore, Inc. reported that a record 36.0 billion videos were viewed online in the United States during the month of December 2010, compared to 33.2 billion videos viewed in December 2009, an increase of approximately 8.4 percent year-over-year. ComScore also noted that over 85 percent of the U.S. audience viewed online video. In a June 2010 report, the Cisco Visual Networking Index projected that global IP traffic will increase by a factor of four from 2009 to 2014. In order to keep up with increased traffic and video demand, service providers will have to continue to improve and expand their carrier Ethernet network infrastructures. In an April 23, 2010 report, Infonetics Research, Inc. forecasts global carrier Ethernet Equipment manufacturer revenue to grow from $21.6 billion in 2009 to over $32.3 billion in 2014.

Traditional telecommunications service providers continue to generate the majority of their revenue from selling traditional voice communications services to consumers and businesses although their revenues may be declining due to competition. Telecommunications service providers are trying to offset any declines in voice revenues by increasing the number of services offered through their networks, such as video applications and other bandwidth intensive data applications. MSOs utilizing hybrid fiber coaxial networks offer voice and data services as competitive alternatives to telecommunications service providers' offerings. Emerging carriers, both regional and those trying to build a national footprint, are offering advanced services based on new and more advanced network infrastructures than the established telecommunications service providers' networks.

To offer new services, telecommunications service providers are investing in increasing the capacity and functionality of their access and metro networks. They are building high-capacity optical networks closer to consumers' homes, business customers and cellular towers to increase the bandwidth capacity and provide scalable and reliable fiber-optic infrastructure. These access networks have the ability to deliver a range of advanced services, such as on-demand high-definition video services, cloud computing, data center disaster recovery, mobility and triple play voice and Internet services.

In addition to investing in access networks, telecommunications service providers need to increase the data capacity of their metro networks and enhance the intelligence, flexibility and efficiency of their networks. As a result, they are investing in optical transport to maximize network utilization as user needs and service offerings change over time. According to the Infonetics report, sales of WDM modules are expected to grow from $2.8 billion in 2009 to $4.9 billion in 2014. WDM uses multiple optical wavelength channels on the same fiber to offer increased data capacity. The WDM multi-channel architecture supports the flexibility to manage, upgrade, and enhance the network on a per-channel basis as requirements change.

Service providers not only utilize vendors for purchasing network equipment, but also seek assistance with network maintenance, network building and network planning and design. An Infonetics report published on April 23, 2010 noted that the global market for service provider outsourcing to vendors is expected to grow from $49 billion in 2009 to $72 billion in 2014, driven primarily by service providers’ need to cut operating expenses through outsourcing.

Generally, moderately improved economic conditions worldwide resulted in an increased demand throughout 2010. This improvement has positively impacted our revenues and operating results. In 2009, our customers took a more cautious approach in their capital expenditures, resulting in order delays, slowing deployments and lengthening

sales cycles. In 2010, our customers resumed investments in their networks to meet the growth in consumer and enterprise use of high-bandwidth communications services. We believe in our long-term market opportunities, but we are uncertain for how long the aftereffects of the economic downturn will continue, or if any recovery will be more than temporary, and how our customers will interpret and react to market conditions. Predicated on our improved 2010 results in comparison to 2009, we continue to believe that the end markets are strong and will continue to recover as general global economic conditions stabilize.

Optical Transport Products

Optical transport networks enable high-bandwidth video, voice and data services by providing efficient fiber optimization, redundancy, distance extension, media conversion and security. Optical transport refers to the transmission of data signals as light pulses, driven by either a laser or light emitting diode, through a fiber optic cable. One of the more common techniques utilized for fiber optimization is WDM, in which each signal or channel is carried over a different wavelength. Each wavelength is multiplexed and passed through a single optical fiber to the receiving end, where the signals are then separated by wavelength.

Our direct competitors in networking products, switches, routers and media converters generally include: ADVA Optical Networks, Alcatel-Lucent, BATM Advanced Communications, BTI Systems, Inc., Canoga Perkins Corp., Ciena Corporation, Cisco Systems, Inc., Cyan Optics, Inc., ECI Telecom Ltd., Ekinops SYS, Ericsson, Extreme Networks, Fujitsu Limited, Huawei Technologies Inc., Nokia Siemens Networks BV, Omnitron Systems Technology, Inc., Optelian, RAD Data Communications, Ltd., Tellabs, Inc., Transition Networks and Transmode.

Many of our larger competitors offer customers a broader product line, which provides a more comprehensive networking solution than we provide. Accordingly, in certain regional markets we have collaborated with other vendors in an effort to enhance our overall capability in providing products and services.

We believe the principal competitive factors in the markets in which we compete include:


•	Product performance, features, quality and price;


•	A comprehensive range of complementary products and services;


•	Customer service and technical support;


•	Lead and delivery times;


•	Timeliness of new product introductions;


•	Global presence, including distribution network;


•	Conformance to standards; and


•	Brand name recognition.

Product Development and Engineering

We believe that in order to maintain our technological competitiveness and to serve our customers better, we must enhance our existing products and continue to develop new products. Accordingly, our Network Equipment group focuses a significant amount of resources on product development and engineering. Product development and engineering expenses were $21.8 million, $22.7 million, and $22.9 million for the years ended December 31, 2010, 2009, and 2008, respectively.

Financial information for each of the principal segments for revenues, measures of profit or loss and total assets, and breakdown by geographic regions are included in Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Item 8 "Financial Statements and Supplemental Data" of this Form 10-K.

Manufacturing and Components

We outsource our board-level assembly and on some occasions, complete turnkey production, to independent contract manufacturers for our networking products, which include switches and routers, remote device management products and networking physical infrastructure equipment. We believe outsourcing allows us to react more quickly to market demand, avoid the significant capital investment required to establish automated manufacturing and assembly facilities and concentrate resources on product design and development. Our in-house manufacturing operations for networking products primarily perform the functions of materials management, quality assurance, as well as inspection and final testing. Our manufacturing processes and procedures are generally ISO 9001 certified and so are those of our electronic manufacturing service providers.

Intellectual Property

To date, we have relied principally on a combination of patents, copyrights and trade secrets to protect proprietary technology. Generally, we enter into confidentiality agreements with our employees and key suppliers and otherwise seek to limit access to and distribution of the source code to software and other proprietary information. These steps may not be adequate to prevent misappropriation of our technologies, or a third party may independently develop technologies similar or superior to any that we possess.

Employees

As of December 31, 2010, MRV employed 743 full-time employees. Of these employees, 279 were in manufacturing, 153 were in product development and engineering, and 311 were in sales, marketing and general administration. Of these employees, 567 work in locations outside the United States. None of our employees are represented by a union or governed by a collective bargaining agreement.

We believe our employee relationships are satisfactory. We believe that our long-term success depends in part on our continued ability to recruit and retain qualified personnel. The risks associated with dependence on qualified personnel are more fully discussed under the heading "The loss of key management could negatively affect our business" in the "Risk Factors" section contained in Item 1A of this Form 10-K.

Internet Access to Our Financial Documents

We maintain a website at www.mrv-corporate.com. We make available on our website, free of charge, reports and proxy statements that we electronically file with or furnish to the SEC. We make the reports available on our website as soon as reasonably practicable after filing or furnishing such reports to the SEC. These reports include Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act. These reports are also available directly through the SEC's website at www.sec.gov.

Item 1A. Risk Factors.

The following risk factors and other information included in this Form 10-K should be carefully considered. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or which we currently deem immaterial also may impair our business operations. If any of the following risks occur, our business, financial condition, operating results, and cash flows could be materially adversely affected and the trading price of our Common Stock could decline.

Our operating results may be adversely impacted by worldwide economic and political uncertainties and specific conditions in the markets we address, including the cyclical nature of and volatility in the network equipment and integration industries.

We operate in the network equipment and integration industries. From time to time, these industries and the markets in which we operate have experienced significant downturns, such as the most recent global downturn. These downturns are characterized by decreases in product demand, excess customer inventories, and accelerated erosion of prices, and may be interspersed with or followed by significant and temporary increased demand in products. Further, these industries are cyclical and subject to rapid change and evolving industry standards. These factors could cause substantial fluctuations in our revenue, gross margins and results of operations, and may cause difficulty in predicting demand and short-term production needs. In addition, during these downturns some competitors become more aggressive in their pricing practices, which may adversely impact our product gross margins. Any downturns in the network equipment and integration industries may be severe and prolonged or intermittent, and any failure to fully

Table of Contents

recover from downturns of these industries or the markets in which we operate could seriously impact our revenue and harm our business, financial condition and results of operations. The network equipment and integration industries also periodically experience increased demand and production capacity constraints, which may affect our ability to ship products in a timely manner and may cause delivery time penalties. Accordingly, our operating results may vary significantly as a result of the general conditions in the network equipment and integration industries, which could cause large fluctuations in our stock price.

Many other factors have the potential to significantly impact our business, such as concerns about inflation and deflation, deterioration in credit availability due to economic downturns or instability on a local or global level, volatility in energy costs, decreased consumer confidence, reduced corporate profits and capital spending, adverse business conditions and liquidity concerns in the communications markets, reduced availability of insurance coverage or reduced ability to pay claims by insurance carriers, recent international conflicts and terrorist and military activity, and the impact of natural disasters and public health emergencies. These conditions may make it extremely difficult for our customers, our vendors and us to accurately forecast and plan future business activities, and they could cause U.S. and foreign businesses to reduce spending on our products and services, which would delay and lengthen sales cycles. Furthermore, during challenging economic times our customers may face issues gaining timely access to sufficient credit or could even need to file for bankruptcy. Either of these circumstances could result in an impairment of their ability to make timely payments to us. If these circumstances were to occur, we may be required to increase our allowance for doubtful accounts. Historically, our business does not come from the end-customer directly, and we have experienced growth patterns that are different than what the end demand might be, particularly during periods of high volatility. This can manifest itself in periods of growth in excess of our customers' growth followed by periods of under-shipment before the volatility abates as our customers adjust their inventory levels. Given recent economic conditions it is possible that any correlation will continue to be less predictable and will result in increased volatility in our operating results and stock price. We cannot predict the timing, strength or duration of any economic slowdown or recovery, worldwide, in the network equipment and infrastructure industries or in the markets in which we operate. If the economy or the markets in which we operate deviate from present levels or deteriorate, we may record additional charges related to restructuring costs and the impairment of goodwill and long-lived assets, and our business, financial condition and results of operations may be materially and adversely affected. Additionally, the combination of our lengthy sales to delivery cycle coupled with challenging macroeconomic conditions could have a synergistic negative impact on the results of our operations. The impact of market volatility is not limited to revenue but may also affect our product gross margins and other financial metrics. Such impact could be manifested in, but not limited to, factors such as fixed cost overhead absorption.

Our quarterly operating results are subject to significant fluctuations, and you should not rely on them as an indication of our future performance. Our operating results could fluctuate significantly from quarter to quarter and year to year.

Our operating results for a particular quarter are difficult to predict. Our revenue, gross margins and operating results could fluctuate substantially from quarter to quarter and from year to year as a whole, and within our business segments. This could result from any one or a combination of factors such as:


•	the cancellation or postponement of orders from one period to the next;


•	the timing and amount of significant orders;


•	the mix in any period of higher and lower margin products and services;


•	software, hardware or other errors in the products we sell requiring replacements or increased warranty reserves;


•	charges for excess or obsolete inventory;


•	our annual reviews of goodwill and other intangibles that lead to impairment charges;


•	the ability of our suppliers to produce and deliver components and parts, including sole or limited source components, in a timely manner, in the quantity and quality desired and at the prices we have budgeted;


•	readiness of customer sites for installation;


•	political stability in the areas of the world in which we operate;


•	price reductions that we make, such as marketing decisions that we have made in the past to reduce the price for our products in an effort to secure new customers or to provide competitive bulk discounts;


•	decreases in average selling prices of our products which result from factors such as overcapacity and market conditions, the introduction of new and more technologically advanced products, and increased sales discounts;


•	the relative success of our efforts to continually reduce product manufacturing costs;


•	our introduction of new products, with initial sales at relatively small volumes with resulting higher production costs, and the rate of market acceptance of the products;


•	delays or reductions in customer purchases of our products in anticipation of the introduction of new and enhanced

Table of Contents

products by us or our competitors;


•	the timing of capital spending of our customers;


•	currency fluctuations;


•	the ability of our customers to pay for our products;


•	general economic conditions; and


•	changes in conditions specific to our business segments.

Moreover, the volume and timing of orders we receive during a quarter are difficult to forecast. Customers often view the purchase of our products as a significant and strategic decision. As a result, customers typically expend significant effort in evaluating, testing and qualifying our products and our manufacturing process. This customer evaluation and qualification process frequently results in a lengthy initial sales cycle of up to one year or more. We may also expend significant management effort, increase manufacturing capacity and order long lead-time components or materials prior to receiving an order. Further, our customers encounter uncertain and changing demand for their products. Customers generally order based on their forecasts. If demand falls below these forecasts or if customers do not control inventories effectively, they may cancel or reschedule shipments previously ordered from us even after acceptance of orders. We do not recognize revenue until a product has been shipped to a customer, all significant vendor obligations have been performed, and collection is considered reasonably assured. Our expense levels during any particular period are based, in part, on expectations of future sales. If sales in a particular quarter do not meet expectations, our operating results could be materially adversely affected.

We expect revenue and gross margins generally and for specific products and services to continue to fluctuate from quarter to quarter and year to year. Changes in service gross margin may result from various factors such as changes in the mix between technical support services and advanced services, as well as the timing of support service contract initiations and renewals. It is possible that, in future periods, our results of operations will be below the expectations of public market analysts and investors. This failure to meet expectations could cause the trading price of our Common Stock to decline. Similarly, the failure by our competitors or customers to meet or exceed the results expected by their analysts or investors could, by association, cause our stock price to decline.

Competition is ever increasing, and we face additional challenges when entering into new markets which could reduce our revenue and gross margins or cause us to lose market share.

The network equipment and integration industries are intensely competitive, and we must continually provide new products while dealing with increased price competition from low-cost producers in Asia or elsewhere. We are further looking to expand our provision of services, and the markets in which we currently offer our products and services. These efforts expose us to additional competition and will likely increase demands on our service and support operations. Our direct competitors in networking products, switches, routers and media converters generally include: ADVA Optical Networks, Alcatel-Lucent, BATM Advanced Communications, BTI Systems, Inc., Canoga Perkins Corp., Ciena Corporation, Cisco Systems, Inc., Cyan Optics, Inc., ECI Telecom Ltd., Ekinops SYS, Ericsson, Extreme Networks, Fujitsu Limited, Huawei Technologies Inc., Nokia Siemens Networks BV, Omnitron Systems Technology, Inc., Optelian, RAD Data Communications, Ltd., Tellabs, Inc., Transition Networks and Transmode.

Many of our competitors have significantly greater financial, technical, marketing, distribution, sales and customer support organizations and other resources and larger installed customer bases than we have. Our competitors continually introduce new competitive products, and may be able to devote greater resources to the development, promotion, sale and support of their products. They may also be able to leverage their buying power with vendors to give them preferential treatment in delivery of high-demand products in times of supply constraint. Many of our larger competitors offer customers broader product lines, which provide a more comprehensive networking solution than we provide. These companies can leverage their customer bases and broader product offerings and adopt aggressive pricing policies to gain market share. In addition, several of our competitors have large market capitalizations, have substantially larger cash reserves, and are much better positioned than we are to acquire other companies in order to gain new technologies or products that may displace our product lines and give them a strategic advantage. Accordingly, in certain regional markets we have collaborated with other vendors in an effort to enhance our overall capability in providing products and services, and we have begun a new focus on consolidating purchasing programs globally to improve our purchasing power with vendors.

Additional competitors may enter the market, and we are likely to compete with new companies in the future. Companies competing with us may introduce products that are more competitively priced, have increased performance or functionality, or incorporate technological advances that we have not yet developed or implemented, and may be able to react more quickly to changing customer requirements and expectations. There is also the risk that other

Table of Contents

network system vendors may enter or re-enter the subsystem market and begin to manufacture in-house the networking subsystems incorporated into their network systems. We also expect to encounter potential customers that, because of existing relationships with our competitors, are committed to the products offered by these competitors. As a result of the foregoing factors, we expect that competitive pressures may result in price reductions, reduced or negative margins or loss of market share in our markets.

Our markets are subject to rapid technological change, and to compete effectively, we must continually introduce new products that achieve market acceptance.

The markets for our products are characterized by rapid technological change, frequent new product introductions, changes in customer requirements and evolving industry standards. We expect that new technologies will emerge as competition and the need for higher and more cost effective transmission capacity, or bandwidth, increases. Our future performance will depend on the successful acquisition or development, organically or inorganically of new and enhanced products that address these changes and other customer requirements. The introduction of new and enhanced products may cause our customers to defer or cancel orders for existing products. We have in the past experienced delays in product development and these delays may occur in the future. Therefore, to the extent that customers defer or cancel orders in the expectation of a new product release or there is any delay in development or introduction of our new products or enhancements of our products, our operating results would suffer.

During the years ended December 31, 2010 and 2009, research and development expenses accounted for eight percent and nine percent of revenues, respectively. Introduction of new products and product enhancements will require that we effectively transfer production processes from research and development to manufacturing and coordinate our efforts with those of our suppliers to achieve volume production rapidly. If we fail to transfer production processes effectively, develop product enhancements or introduce new products in sufficient quantities to meet the needs of our customers as scheduled, our net sales may be reduced and our business may be harmed. We also may not be able to develop the underlying core technologies necessary to create new products and enhancements, or to license these technologies from third parties. Product development delays may result from numerous factors, including:


•	changing product specifications and customer requirements;


•	difficulties in hiring and retaining necessary technical personnel;


•	difficulties in reallocating engineering resources and overcoming resource limitations;


•	difficulties with contract manufacturers;


•	changing market or competitive product requirements; and


•	unanticipated engineering complexities.

The acquisition or development of new, technologically advanced products is a complex and uncertain process requiring high levels of innovation and highly skilled engineering and development personnel, as well as the accurate anticipation of technological and market trends. In order to compete, we must be able to deliver to customers products that are highly reliable, operate with their existing equipment, lower their costs of acquisition, installation and maintenance, and provide an overall cost-effective solution. We may not be able to identify, develop, manufacture, market or support new or enhanced products successfully, if at all, or on a timely basis. Further, our new products may not gain market acceptance or we may not be able to respond effectively to product announcements by competitors, technological changes or emerging industry standards. Our failure to respond effectively to technological changes would significantly harm our business.

Our products are deployed in large and complex systems and may contain defects that are not detected until after our products have been installed, which may cause us to incur significant costs, divert our attention from product development efforts, or damage our reputation and cause us to lose customers.

Our products are complex and undergo internal quality testing and qualification as well as formal qualification by our customers. However, defects may be found from time to time. Our customers' testing procedures are limited to evaluating our products under likely and foreseeable failure scenarios and over varying amounts of time. For various reasons, including among others, the occurrence of performance problems that are unforeseeable in testing or that are detected only when products age or are operated under peak stress conditions, our products may fail to perform as expected long after customer acceptance. Failures could result from faulty components or design, problems in manufacturing or other unforeseen reasons. As a result, we could incur significant costs to repair and/or replace defective products under warranty, particularly when such failures occur in installed systems. We have experienced such failures in the past and will continue to face this risk going forward, as our products are widely deployed throughout the world in multiple demanding environments and applications. In addition, we may in certain circumstances honor

Table of Contents

warranty claims after the warranty period has expired or for problems not covered by warranty in order to maintain customer relationships. We believe that our warranty reserves adequately address our potential exposure to liability for warranty claims. Our warranty reserves are based on historical return rates, and our average material costs incurred to repair items, including labor costs. The warranty reserves are evaluated and adjusted based on updated actual experience.

In addition, certain of our networking products are typically embedded in, or deployed in conjunction with, our customers' products, which incorporate a variety of components and may be expected to interoperate with modules produced by third parties. As a result, not all defects are immediately detectable and when problems occur, it may be difficult to identify the source of the problem. These problems may cause us to incur significant damages or warranty and repair costs, divert the attention of our engineering personnel from our product development efforts, cause significant customer relation problems or loss of customers, and harm our reputation and brand, any of which could materially and adversely affect our business.

Although we were profitable on a consolidated basis in the year ended December 31, 2010, we had not achieved profitability on a consolidated basis for several years prior to that, and may not achieve profitability in the future.

Although we were profitable on a consolidated basis in the year ended December 31, 2010, we reported net losses for 2005 through 2009. We expect to continue to incur significant product development, sales and marketing and general and administrative expenses, and costs related to improving manufacturing efficiency. As a result, we will need to continue our efforts to contain expense levels and increase revenue levels in an effort to achieve profitability in the future. In 2008 and 2009, we incurred additional significant charges related to the investigation and restatement of our financial statements, and in 2009, we incurred expenses related to a proxy contest for the election of directors. In 2010 we incurred charges related to a settlement of outstanding patent litigation with Finisar Corporation. We may not be successful in our efforts to contain expense levels and increase revenue levels, and we may not attain profitability on a sustained basis or at all.

Our customers may adopt alternate technologies for which we do not produce products or for which our products are not adaptable.

The market for our products is characterized by rapidly changing technology, evolving industry standards and new product introductions, which may minimize the demand for our existing products or render them obsolete. Our future success will depend in part upon our ability to enhance existing products and to develop and introduce new products that address such changes in technology and standards and respond to our customers' potential desire to adopt such technologies in place of those supported by our current product offerings. The development of new or enhanced products is a complex and uncertain process requiring the accurate anticipation of technological and market trends as well as precise technological execution. Further, the development cycle for products integrating new technologies or technologies with which we are not as familiar may be longer and more costly than our current product development process. We may experience difficulties that could delay or prevent the successful development, introduction and marketing of these new products, and the new products may not be successfully commercialized. These costs and delays may prevent us from being able to establish a market position with respect to such new technologies and industry standards or be as responsive as we would like to be in meeting our customers' demands for such products, thus adversely affecting our results of operations and our customer relationships.

We do not have many long-term volume purchase contracts with our customers, so our customers may increase, decrease, cancel or delay their purchasing levels at any time with minimal advance notice to us, which may significantly harm our business.

Our customers typically purchase our products pursuant to individual purchase orders. While our customers generally provide us with their demand forecasts, in most cases they are not contractually committed to buy any quantity of products beyond firm purchase orders. Our customers may increase, decrease, cancel or delay purchase orders already in place. If any of our major customers decrease, stop or delay purchasing our products for any reason, our business and results of operations would be harmed. Cancellation or delays of such orders may cause us to fail to achieve our short- and long-term financial and operating goals. Lead times for components and materials that we order vary significantly and depend on factors including the specific supplier requirements, the size of the order, contract terms and current market demand for components. For substantial increases in our sales levels, some of our suppliers may need significant lead time. In the past, during periods of market downturns, certain of our largest customers canceled or delayed significant orders with us and with our competitors, which resulted in losses of sales and excess

Table of Contents

and obsolete inventory. Similarly, decreases or deferrals of purchases by our customers may significantly harm our industry and specifically our business in these and in additional unforeseen ways, particularly if they are not anticipated.

We may suffer losses as a result of entering into fixed price contracts.

From time to time we enter into contracts with certain customers in which the price we charge for particular products is fixed. Although our estimated production costs for these products are used to compute fixed sales prices, if actual production costs exceed the estimated production costs because of our inability to obtain needed components timely, or at all, or we cannot continue to cut costs in production and have incrementally decreased future fixed prices, we may incur a loss on the sale. Sales of material amounts of products on a fixed price basis, for which we have not accurately forecast the production costs, could have a material adverse effect on our results of operations.

A few customers account for a substantial portion of our sales, increasing both our dependence on a few revenue sources and the risk that our operations will suffer materially if a significant customer stops ordering from us or substantially reduces its business with us.

One customer of our Network Integration group accounted for 17%, 15% and 10% of revenue in the years ended December 31, 2010, 2009 and 2008, respectively. While our financial performance benefited from substantial sales to this customer, because of the magnitude of sales to the customer, our results would suffer if we were to lose its business. Additionally, if that customer, or other significant customers made a substantial reduction in orders our results of operations would suffer unless we were able to replace the customer or orders with one or more customers of comparable size.

Our ability to utilize our NOLs and certain other tax attributes may be limited.

As of December 31, 2010, MRV had federal, state and foreign net operating losses, or NOLs, of $176.5 million, $156.8 million and $88.7 million, respectively. Under Section 382 of the Internal Revenue Code, if a corporation undergoes an "ownership change," the corporation's ability to use its pre-change NOLs, capital loss carry forwards and other pre-change tax attributes to offset its post-change income, may be limited. An ownership change is generally defined as a greater than 50% change in its equity ownership by value over a three-year period. We may experience an ownership change in the future as a result of subsequent shifts in our stock ownership. If we were to trigger an ownership change in the future, our ability to use any NOLs and capital loss carry forwards existing at that time could be limited.

We face risks in reselling the products of other companies.

We distribute products manufactured by other companies. To the extent we succeed in reselling the products of these companies, or products of other vendors with which we may enter into similar arrangements, we may be required by customers to assume warranty and service obligations. While these suppliers have agreed to support us with respect to those obligations, if they should be unable, for any reason, to provide the required support, we may have to expend our own resources on doing so. We are unable to evaluate fully the potential magnitude of these warranty claims as the equipment has been designed and manufactured by others.

There are a limited number of potential source suppliers for certain components, which makes us susceptible to supply shortages.

We currently purchase several key components from single or limited sources. Moreover, we depend on the quality of the products supplied to us, over which we have limited control. We have encountered shortages and delays in obtaining components in the past and expect to encounter shortages and delays in the future. Sudden significant increases in demand for products which we purchase may cause delays in delivery of subcomponents, which may cause delay in delivery of our products. Larger competitors may be able to demand more rapid delivery of components parts in comparison to us. If we cannot supply products due to a lack of certain components or are unable to redesign products with other components in a timely manner, our business will be significantly harmed.

We typically have not entered into long-term agreements with our suppliers and, therefore, our suppliers could stop supplying materials and equipment at any time or fail to supply adequate quantities of component parts on a timely basis. It is difficult, costly, time consuming and, on short notice, sometimes impossible for us to identify and qualify new component suppliers. The reliance on a sole supplier, single qualified vendor or limited number of suppliers could result in delivery and quality problems, reduced control over product pricing, reliability and performance and an

Table of Contents

inability to identify and qualify another supplier in a timely manner. We have in the past had to change suppliers, which, in some instances, has resulted in delays in product development and manufacturing until another supplier was found and qualified. Any such delays in the future may limit our ability to respond to changes in customer and market demands. During the last several years, the number of suppliers of components has decreased significantly and, more recently, demand for components has increased. Any supply deficiencies relating to the quality or quantities of components we use to manufacture our products could adversely affect our ability to fulfill customer orders and our results of operations.

We rely substantially upon a limited number of contract manufacturing partners, and if these contract manufacturers fail to meet our short- and long-term needs and contractual obligations, our business may be negatively impacted.

We rely to a significant extent on a limited number of contract manufacturers to assemble, manufacture and test our products. The qualification and set up of these independent manufacturers under quality assurance standards is an expensive and time-consuming process. Certain of our independent manufacturers have a limited history of manufacturing optical modules or other components we use in our products and equipment. In the past, we have experienced delays or other problems, such as inferior quality, insufficient quantity of product and an inability to meet cost targets, which have led to delays in our ability to fulfill customer orders. Additionally, in the past, we have been required to qualify new contract manufacturing partners and replace contract manufacturers, which led to delays in deliveries. Any future interruption in the operations of these manufacturers, or any deficiency in the quality, quantity or timely delivery of the components or products built for us by these manufacturers, could impede our ability to meet our scheduled product deliveries to our customers or require us to contract with and qualify new contract manufacturing partners. As a result, we may lose existing or potential customers or orders and our business may be negatively impacted.

If we fail to forecast component and material requirements accurately, we could incur additional costs or experience manufacturing delays.

We use rolling forecasts based on anticipated product orders to determine our component and material requirements. It is very important that we accurately predict both the demand for our products and the lead times required to obtain the necessary components and materials. Lead times for components and materials that we order vary significantly and depend on factors such as specific supplier requirements, the size of the order, contract terms and current market demand for the components. For substantial increases in production levels, some suppliers may need six months or more lead time. If we overestimate our component and material requirements, we may have excess or obsolete inventory, which may not get used or have to be discounted to eliminate. If we underestimate our component and material requirements, we may have inadequate inventory, which could interrupt our manufacturing and delay delivery of our products to our customers. Any of these occurrences would negatively impact our revenue.

Our business and future operating results may be adversely affected by events outside of our control.

We use our facilities in California, Massachusetts and Israel for major product design and development and customer support, and we manufacture products at our facilities in California, Taiwan and Israel. The risk of earthquakes in Southern California and Taiwan is significant because of the proximity of these manufacturing facilities to major earthquake fault lines. In January 1994 and September 1999, major earthquakes near Chatsworth, California and in Taiwan, respectively, affected our facilities, causing power and communications outages and disruptions that impaired production capacity. While our facilities did not suffer material damage and our business was not materially disrupted by these earthquakes, the occurrence of an earthquake or other natural disaster could result in the disruption of our manufacturing facilities. Any disruption in our manufacturing facilities arising from earthquakes, other natural disasters or other catastrophic events including wildfires and other fires, excessive rain, terrorist attacks and wars, could disrupt our manufacturing ability, which could harm our operations and financial results, and could cause significant delays in the production or shipment of our products until we are able to shift production to different facilities or arrange for third parties to manufacture our products. We may not be able to obtain alternate capacity on favorable terms or at all. The location of our manufacturing facilities subjects us to increased risk that a natural disaster could disrupt our operations.

Although we believe our insurance coverage is adequate to address the variety of potential liabilities we face, our insurance coverage is subject to deductibles and coverage limits. Upon an occurrence of a significant natural disaster, or manmade problems such as computer viruses, civil war, terrorism, blackout or disruptions to the economies of the United States and other countries, such coverage may not be adequate or continue to be available at commercially reasonable rates and terms. In the event of a major earthquake or other disaster affecting one or more of our facilities, our operations could be significantly disrupted, delayed or prevented for the time required to transfer production, repair,

Table of Contents

rebuild or replace the affected manufacturing facilities. This time frame could be lengthy, and result in significant expenses for repair and related costs. In addition, concerns about an outbreak of epidemic diseases such as avian or swine influenza or severe acute respiratory syndrome, could have a negative effect on travel and our business operations, and result in adverse consequences to our business and results of operations.

Environmental regulations applicable to our manufacturing operations could limit our ability to expand or subject us to substantial costs. Compliance with current and future environmental regulations may be costly which could impact our future operating results.

We are subject to a variety of environmental regulations relating to the use, storage, discharge and disposal of hazardous chemicals used during our manufacturing processes. Further, we are subject to other safety, labeling and training regulations as required by foreign, local, state and federal law. We believe we are compliant in all material respects with applicable environmental regulations in the United States, Taiwan and Israel. However, any failure by us to comply with present and future regulations could subject us to future liabilities or the suspension of production. In addition, such regulations could restrict our ability to expand our facilities and we may need to acquire costly equipment or incur other significant expenses to comply with environmental regulations. We cannot provide assurance that legal requirements will not be imposed on us that would require additional capital expenditures or the satisfaction of other requirements. If we fail to obtain required permits or otherwise fail to operate within current or future legal requirements, including those applicable to us in the United States, Taiwan and Israel, we may be required to pay substantial penalties, suspend our operations, or make costly changes to our manufacturing processes or facilities.

In addition, we could face significant costs and liabilities in connection with legislation which enables customers to return a product at the end of its useful life and charges us with financial and other responsibility for environmentally safe collection, recycling, treatment and disposal. We also face increasing complexity in our product design and procurement operations as we adjust to new and upcoming requirements relating to the materials composition of our products, and disclosure related to the origin of certain raw materials used in our products. This includes the restrictions on lead and certain other substances in electronics that apply to specified electronics products put on the market in the European Union and the People's Republic of China ("PRC"). Many of our customers have adopted this approach and have required our full compliance. Even though we have devoted a significant amount of resources and effort planning and executing our compliance program and believe that we are in compliance with such legislation, it is possible that some of our products might be incompatible with such regulations. In such event, we could experience loss of revenue, damaged reputation, diversion of resources, monetary penalties and legal action. Other environmental regulations may require us to re-engineer our products to utilize components that are more environmentally compatible. Such re-engineering and component substitution may result in additional costs to us. Although we currently do not anticipate any material adverse effects based on the nature of our operations and the effect of such laws, there is no assurance that such existing laws or future laws will not have a material adverse effect on us.

Our business and future operating results are subject to a wide range of uncertainties arising out of the international nature of our operations and facilities.

International sales accounted for 79%, 79%, and 77% of revenues for the years ended December 31, 2010, 2009, and 2008, respectively.

We have offices and facilities in, and conduct a significant portion of our operations in and from, France, Israel, Italy, Sweden, Switzerland and Taiwan. We are, therefore, influenced by the political and economic conditions affecting these countries. Risks we face from international sales and our use of facilities and suppliers overseas for manufacturing include:


•	ensuring compliance with local regulations and laws in each country and locality in which we do business;


•	greater difficulty in accounts receivable collection and longer collection periods;


•	the impact of recessions in economies outside the United States;


•	changes in regulatory requirements;


•	seasonal reductions in business activities in some parts of the world, such as during the summer months in Europe;


•	difficulties in managing operations across disparate geographic areas;


•	difficulties associated with enforcing agreements through foreign legal systems;


•	the payment of operating expenses in local currencies, which exposes us to risks of currency exchange rate fluctuations;


•	higher credit risks requiring cash in advance or letters of credit;


•	potentially adverse tax consequences, increasing taxes, and heightened efforts by officials of foreign countries to

Table of Contents

increase revenues from tax collection;


•	unavailability or delays in delivery of equipment, raw materials or key components;


•	trade restrictions, tariff increases and increasing import-export duties;


•	shipping delays;


•	limited protection of intellectual property rights;


•	tightening immigration controls that may adversely affect the residency status of our engineers and other key employees in our U.S. facilities who are not permanent residents of the United States, or our ability to hire new non-U.S. employees in our U.S. facilities; and


•	increasing foreign environmental regulation or unforeseen environmental problems.

Our business and operations are also subject to general geopolitical conditions, such as terrorism, political and economic instability, changes in the costs of key resources such as crude oil and changes in diplomatic or trade relationships. Economic conditions in several countries and markets outside the United States in which we have offices, personnel, facilities or sales represent significant risks to us. Instability in the Middle East, PRC or the European Union could have a negative impact on our sales and operations in these regions, and unstable conditions could have a material adverse effect on our business and results of operations. In addition to the effect of global economic instability on our operations or facilities on sales to customers outside the United States, sales to domestic customers could be negatively impacted by these conditions.

Our operating results are impacted by foreign exchange rates and interest rate fluctuations.

Our interest income and expense is impacted by fluctuations in interest rates. Changes in foreign exchange rates impact us in four ways. Several of our foreign business units have a functional currency other than the U.S. dollar. The amount of revenue, expenses, assets and liabilities measured in U.S. dollars is impacted by changes in exchange rates. Our revenues and profits have been negatively affected in 2010 because of the strength of the U.S. dollar relative to the currencies in which these business units report their results. Further, fluctuations in currency exchange rates can and do cause our products to become relatively more expensive in particular countries, leading to a reduction in sales in that country. The proportion of our costs incurred in various currencies varies from the proportion of revenues denominated in that currency which may materially impact our gross margins. Some of our accounts receivable, cash balances, accounts payable, credit lines, and other assets and liabilities are denominated in currencies other than the related business unit's functional currency. Increases or decreases in the expected amount of cash flow result in foreign exchange gains or losses which impact our profitability. We currently do not have any hedging or swap agreements in place other than intra-quarter currency hedges at one of our subsidiaries. Where possible, we attempt to denominate sales in countries in which we do business in the local currency, to match the proportion of cost and revenues transacted in each currency, and to match the assets and liabilities held in each currency which helps to reduce foreign exchange rate exposure to some degree. We could incur losses from our hedging activities or our lack of hedging activities in the future. In addition, inflation or fluctuations in currency exchange or interest rates in any of the countries that we do business could increase our operating expenses and thereby adversely affect our results of operations.

Failure to comply with the U.S. Foreign Corrupt Practices Act could subject us to penalties and other adverse consequences. We could suffer losses from corrupt or fraudulent business practices.

We are subject to the U.S. Foreign Corrupt Practices Act ("FCPA") which generally prohibits U.S. companies from engaging in bribery or making other prohibited payments to foreign officials for the purpose of obtaining or retaining business. In addition, we are required to maintain records that accurately and fairly represent our transactions and have an adequate system of internal accounting controls. Foreign companies, including some that may compete with us, are not subject to these prohibitions, and therefore may have a competitive advantage over us. We have implemented and maintained preventative measures, but cannot assure that our employees or other agents will not engage in such conduct and render us responsible under the FCPA. If our employees or other agents are found to have engaged in these practices, we could suffer severe penalties and other consequences that may have a material adverse effect on our business, financial condition and results of operations.

We have significant cash reserves due to the sale of Source Photonics, but we may not be able to deploy our current cash reserves in a profitable manner, and if additional capital resources are desired, we may not be able to obtain capital on favorable terms, if at all.

We have significant cash reserves due to the sale of Source Photonics. We may not be able to find suitable opportunities to reinvest the cash, which would adversely impact our return on capital, or we may make investments that do not yield the expected returns. If we deploy a substantial portion of the cash reserves, we may need additional

Table of Contents

financing to execute on our current or future business strategies, including to:


•	acquire businesses or technologies;


•	make investments in capital equipment, facilities and technology in order to grow organically;


•	improve our operating and manufacturing infrastructure; or


•	otherwise respond to competitive pressures.

Our ability to raise financial capital in the future may be hindered due to our previous net losses and the possibility of future negative cash flow. If adequate funds are not available or are not available on acceptable terms, if and when needed, our ability to conduct acquisitions, make organic investments in our businesses, take advantage of unanticipated opportunities, or otherwise respond to competitive pressures, could be significantly limited.

If we fail to protect our intellectual property, we may not be able to compete.

We rely on a combination of trade secret laws and restrictions on disclosure and patents, copyrights and trademarks to protect our intellectual property rights. We cannot assure you that our pending patent and trademark applications will be approved, that any patents or trademarks that may be issued will protect our intellectual property or that third parties will not challenge any issued patents. Other parties may independently develop similar or competing technology or design around any patents that may be issued to us. We cannot be certain that the steps we have taken will prevent the misappropriation of our intellectual property, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. Specifically there is a risk of poor enforcement of intellectual property rights in the PRC, where the validity, enforceability and scope of protection of intellectual property is uncertain and still evolving. Policing unauthorized use of proprietary technology is difficult and expensive. Reverse engineering, unauthorized copying or other misappropriation of our proprietary technologies could enable competitors, especially in PRC, to benefit from our technologies without paying us any royalties. Enforcing our intellectual property rights or resolving intellectual property disputes may involve litigation. Any of this kind of litigation, regardless of outcome, could be expensive and time consuming, and adverse determinations in any of this kind of litigation could seriously harm our business.

We are involved in intellectual property disputes from time to time as part of doing business in the network equipment industry, which could divert management's attention, cause us to incur significant costs, and prevent us from selling or using the challenged technology.

Participants in the network equipment markets in which we sell our products have experienced litigation regarding patent and other intellectual property rights. Numerous patents in these industries are held by others, including our competitors. From time to time, we have become aware of the possibility or have been notified that we may be infringing certain patents or other intellectual property rights of others, and we have been involved in litigation matters regarding intellectual property right claims of others in the past. In addition, we may be a party to litigation to protect our intellectual property. These claims and any resulting lawsuit, if successful, could subject us to significant liability for damages or invalidation of our proprietary rights, and there can be no assurance that we will be successful in our defense and, even if we are successful, we may incur substantial legal fees and other costs in defending the lawsuit. Any lawsuit that we may become party to, regardless of its success, may be time-consuming and expensive to resolve and divert technical and management time and attention. Accordingly, any infringement claim or litigation against us could significantly harm our business, operating results and financial condition. Further, we have agreed to indemnify the buyer of Source Photonics for three years from the date of closing regarding any intellectual property claims that arise from allegations of intellectual property rights violations that occur prior to the closing. In the event of an adverse result in any litigation with respect to intellectual property rights relevant to our products, we could be required to obtain licenses to the infringing technology, to pay substantial damages under applicable law, to cease the manufacture, use and sale of infringing products, or to expend significant resources to develop non-infringing technology. Licenses may not be available from third parties either on commercially reasonable terms or at all.

We are involved in various derivative litigations due to past stock option practices, and the related restatement of our prior financial results.

In connection with our past stock option grant practices, we, and a number of our current and former directors and officers, have been subjected to a number of ongoing stockholder lawsuits. A description of the litigation is set forth in Item 1A. "Legal Proceedings" of this Form 10-K. As a result of this litigation, we have been and remain subject to a number of risks, including the following, each of which could result in a material adverse effect to our business, financial condition and results of operations and/or a negative effect on the market for our stock: (i) private litigation

Table of Contents

relating to our restatement or option grant practices; (ii) indemnification obligations for our former and current directors, officers and employees related to the litigation; (iii) additional significant costs in effectuating on-going or additional remediation actions; and (iv) diversion of the time and attention of members of our management and our Board of Directors from the management of our business.

We are involved in other lawsuits and legal proceedings, and have agreed to indemnify the buyer of Source Photonics for claims arising from allegations occurring prior to the closing.

We are involved in various lawsuits, disputes and claims, arising in the ordinary course of business, and have agreed to indemnify the buyer of Source Photonics for 15 months from the date of sale for claims arising from allegations occurring prior to the closing that are not related to intellectual property. Our indemnification obligations extend to three years from closing for intellectual property claims. These suits or actions may raise complex factual and legal issues and are subject to uncertainties. Actions filed against us could include product liability, commercial, intellectual property, customer, employment and securities related claims, including class action lawsuits. Plaintiffs (or defendants who counterclaim) may seek unspecified damages or injunctive relief, or both. Although we carry product liability insurance, and believe such coverage is adequate based on the historical rate and nature of customer product quality claims or complaints, we cannot provide assurance that this insurance would adequately cover our costs arising from any significant defects in our products. Adverse results to any lawsuits, disputes or claims may harm our business and have material adverse effects on our results of operations, liquidity or financial position, any or all of which could adversely affect our stock price.

Failure to achieve and maintain internal controls in accordance with Sections 302 and 404 of the Sarbanes-Oxley Act of 2002 could have a material adverse effect on our business and stock price.

We have examined and evaluated our internal control procedures to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, and found no material weaknesses for the year ended December 31, 2010. However, we had one material weakness due to our restatement of our Annual Report on Form 10-K for the year ended December 31, 2009. In our Annual Report on Form 10-K for the year ended December 31, 2008, which we did not file until October 8, 2009, we had reported two material weaknesses for the year then ended, and another that had been remediated during 2008 due to the restatement of our financial statements. If we fail to maintain the internal controls we have recently implemented or fail to implement required new or improved controls, as such control standards are modified, supplemented or amended from time to time, or as our business changes, we may not be able to conclude on an ongoing basis that we have effective internal controls over financial reporting. Effective internal controls are necessary for us to produce reliable financial reports and are important in the prevention of financial fraud. If we cannot produce reliable financial reports or prevent fraud, our business and operating results could be harmed, investors may lose further confidence in our reported financial information, and there could be a material adverse effect on our stock price.

The loss of key management could negatively affect our business.

Our ability to develop, manufacture and market our products, run our operations and our ability to compete with our current and future competitors depends in large part on our ability to attract and retain qualified personnel. Competition for executives and highly-qualified engineers in the network equipment and infrastructure industries is intense, and we will be required to compete for those personnel with companies having substantially greater financial and other resources than we do. We are dependent upon Dilip Singh, our Chief Executive Officer, and other executive officers and general managers of our various business units, especially in places where personal relationships are a significant part of a business transaction. We do not have succession plans in every key position, and the loss of the services of these officers could have a material adverse effect on our operations. If we do not attract necessary team members to operate our business and provide for adequate retention and succession planning, our business could be materially adversely affected.

Delaware law and our ability to issue preferred stock may have anti-takeover effects that could prevent a change in control, which may cause our stock price to decline.

We are authorized to issue up to 1,000,000 shares of Preferred Stock. This Preferred Stock may be issued in one or more series, the terms of which may be determined at the time of issuance by our Board of Directors without further action by stockholders. The terms of any series of preferred stock may include voting rights (including the right to vote as a series on particular matters), preferences as to dividend, liquidation, conversion and redemption rights and sinking fund provisions. No preferred stock is currently outstanding. The issuance of any preferred stock could

Table of Contents

materially adversely affect the rights of the holders of our Common Stock, and therefore, reduce the value of our Common Stock. In particular, specific rights granted to future holders of preferred stock could be used to restrict our ability to merge with, or sell our assets to, a third party and thereby preserve control by the present management. We are also subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which prohibit us from engaging in a business combination with an interested stockholder for a period of three years after the date of the transaction in which the person became an interested stockholder unless the business combination is approved in the manner prescribed under Section 203. These provisions of Delaware law also may discourage, delay or prevent someone from acquiring or merging with us, which may cause the market price of our Common Stock to decline.

There is no assurance of an established public trading market for our Common Stock, which would adversely affect the ability of investors in our Company to sell their Common Stock in the public markets.

Our Common Stock was delisted from trading on the NASDAQ Global Market in August 2009. At present, the OTC "Pink Sheets" is the only public market where investors can trade our Common Stock. The Pink Sheets is an inter-dealer electronic quotation and trading system that provides significantly less liquidity and daily trading volume than a national securities exchange or automated quotation system. Quotes for stocks included in the Pink Sheets are not listed in the financial sections of newspapers as are those for stocks listed on national securities exchanges or automated quotation systems. In the absence of an active trading market, investors may have difficulty buying and selling or obtaining market quotations, and the lack of visibility for our Common Stock may have a depressive effect on the market for our Common Stock.

Item 1B. Unresolved Staff Comments.

There are no unresolved written comments that were received from the SEC's staff 180 days or more before the end of the Company's fiscal year relating to our periodic or current reports filed under the Exchange Act.

Item 2. Properties.

Our properties consist of leased and owned facilities for product development, manufacturing, sales, support, and administrative operations. We believe that our existing properties are in good condition and suitable for the conduct of our business. Should the need arise, we believe that suitable replacement and additional space will be available in the future on commercially reasonable terms subject to force majeure conditions. For additional information regarding obligations under operating leases, see Note 10 to the Consolidated Financial Statements located in Item 8 of this Form 10-K.

Item 3. Legal Proceedings.

We are subject to legal claims and litigation in the ordinary course of business, including but not limited to product liability, employment and intellectual property claims. The outcome of any such matters is currently not determinable. If one or more of the matters listed below or otherwise is ultimately determined not in our favor, it could have a material adverse effect on our consolidated financial position or results of operations in the period in which they occur.

Stock Option Litigation

In June 2008, the Company announced that our Board of Directors, based on information provided by management, and in consultation with management, concluded that the financial statements and the related reports of our independent public accountants should not be relied upon due to the Company's intention to restate its financial

Table of Contents

results from 2002 through 2008 to correct its accounting for option grants and other issues. The Board of Directors appointed a Special Committee of independent directors, along with independent legal counsel and outside accounting experts, to investigate the issues, and a restatement of the Company's financial statements was filed in its Annual Report on Form 10-K for the year ended December 31, 2008 in October 2009.

From June to August 2008, five purported stockholder derivative and securities class action lawsuits were filed in the U.S. District Court in the Central District of California and one derivative lawsuit was filed in the Superior Court of the State of California against the Company and certain of our current and former officers and directors. The five lawsuits filed in the Central District of California were consolidated. Claims were asserted under Section 10(b) and 20(a) of the Exchange Act, and Rule 10b-5 promulgated thereunder. The allegations set forth in the complaints were based on facts disclosed in our press release of June 5, 2008, which stated that the Company's financial statements could not be relied on due to the Company's historical stock option practices and related accounting. The complaints sought to recover from the defendants unspecified compensatory and punitive damages, to require the Company to undertake reforms to corporate governance and internal control procedures, to obtain an accounting of stock option grants found to be improper, to impose a constructive trust over stock options and proceeds derived therefrom, to disgorge from any of the defendants who received allegedly improper stock options the profits obtained therefrom, to rescind improperly priced options and to recover costs of suit, including legal and other professional fees and other equitable relief. In November 2010, the judge overseeing the securities class action lawsuits gave final approval to a stipulated $10 million settlement agreement, which was covered by our director and officer insurance policies.

Motions to dismiss the defendants were heard in the second half of 2010 in both the federal and California state derivative lawsuits, and certain defendants and claims were dismissed. Discovery continues in these matters. The Company and plaintiffs in the federal and state derivative lawsuits have attended mediations but have not been successful in reaching a settlement of these claims.

Fiberxon Acquisition Litigation

In July 2007, we purchased Fiberxon, Inc., and the purchase agreement included possible post-acquisition obligations on MRV. We filed an affirmative lawsuit in the California Superior Court in March 2009 against a) former stockholders, seeking to cancel a potential deferred consideration obligation of approximately $31.5 million, and b) certain former executives, directors and stockholders of Fiberxon, Inc., alleging fraud and other claims. We entered into a Settlement Agreement and Release in December 2009 with Yoram Snir, personally and in his capacity as Stockholders' Agent for the former stockholders of Fiberxon. Pursuant to the settlement agreement, the Company has fully settled any obligation to pay the first $18 million of potential deferred consideration. This amount was reserved for set-off in the original merger agreement, and the former Fiberxon stockholders, pursuant to the settlement, were entitled to their pro rata portion of the $1.5 million settlement amount. Additionally, we agreed to pay up to $4.5 million to settle claims relating to the remaining $13.5 million of the potential deferred compensation. The second portion of the settlement is with the former stockholders directly, and to date, stockholders holding 67% of the former shares have elected to participate in this portion of the settlement.

We maintained the California Superior Court action with four remaining defendants, and in December 2010, the court issued a default judgment against them in the amount of $57.4 million, jointly and severally, for the tort causes of action alleged in MRV's complaint, and ordered that MRV shall have no further obligations under the merger agreement including the deferred payment obligations. The defendants have submitted pleadings with the court to set aside the default judgment. We are currently evaluating the enforceability of this judgment against the defendants who likely may not reside or have assets in the United States. Further, in 2010, four former stockholders who owned approximately 27% of the former Fiberxon and did not participate in the second portion of the settlement, initiated litigation in Beijing, PRC against MRV, Source Photonics LLC and other related parties alleging a claim for approximately $3.7 million, representing these former stockholders' pro rata amount of the $13.5 million portion of the potential deferred compensation. In December 2010, two of the plaintiffs with claims of approximately $0.8 million, voluntarily withdrew their suits without prejudice. In connection with the sale by MRV of Source Photonics in October 2010, we agreed to indemnify the buyer against certain litigation, including these actions.

The results of any litigation are inherently uncertain, and there can be no assurance that we will prevail in the litigation matters stated above or otherwise. We plan to pursue our claims and defenses vigorously and expect that some of the litigation matters discussed above will be protracted and costly.

•	1998 Nonstatutory Stock Option Plan;


•	Stock options issued and outstanding on the effective date of the merger of Luminent under the Luminent Amended and Restated 2000 Stock Option Plan that were assumed by MRV and are exercisable for 0.43 shares of Common Stock for each share of Luminent held under the relevant option;

Table of Contents

"Consolidated Plan").

In 2007, MRV's stockholders approved the Omnibus Plan to consolidate MRV's two outstanding equity compensation plans. The first plan was MRV's expiring 1997 Incentive and Nonstatutory Stock Option Plan, under which all employees, officers, directors and consultants were eligible to participate, and it was submitted to and approved by stockholders. The second plan was the Consolidated Plan, which consolidated all the other bulleted plans listed in footnote (2), and it was not submitted to or approved by stockholders as neither the NASDAQ qualification standards nor federal law or regulation required such approval at the time the Consolidated Plan was adopted.

Upon adoption of the Omnibus Plan, no further shares were available for future grants of options or warrants under the 1997 Incentive and Nonstatutory Stock Option Plan and the plans set forth in the bulleted paragraphs above in footnote (2), including shares that became and become available as a consequence of the cancellation or forfeiture of outstanding options granted under such plans, and all such available shares were rolled into, and become available for, future grants of options and other awards under the Omnibus Plan.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in Item 8 of this Form 10-K. In addition to historical information, the discussion in this Form 10-K contains certain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated by these forward-looking statements. We assume no obligation to update any of the forward-looking statements after the date of this Form 10-K. The following discussion and analysis is organized as follows:


•	Overview


•	Critical Accounting Policies


•	Recently Issued Accounting Standards


•	Currency Rate Fluctuations


•	Results of Operations


•	Liquidity and Capital Resources


•	Off Balance Sheet Arrangements

Overview

We supply communications equipment and services to carriers, governments and enterprise customers, worldwide. We conduct our business along two principal segments: (a) the Network Equipment group; and (b) the Network Integration group. We evaluate segment performance based on the revenues, gross profit and operating expenses of each segment. We do not evaluate segment performance on additional financial information. As such, there are no separately identifiable Statements of Operations data below operating income (loss). Our Network Equipment group provides communications equipment that facilitates access, transport, aggregation and management of voice, data and video traffic in networks, data centers and laboratories used by telecommunications service providers, cable operators, enterprise customers and governments worldwide. Our Network Integration group operates primarily in Italy, France, Switzerland and Scandinavia, servicing Tier One carriers, regional carriers, large enterprises, and government institutions. The Network Integration group provides network system design, integration and distribution services that include products manufactured by third-party vendors, as well as products developed and manufactured by the Network Equipment group. We market and sell our products worldwide, through a variety of channels, which include a dedicated direct sales force, manufacturers' representatives, value-added-resellers, distributors and systems integrators.

On December 24, 2009, we entered into an agreement to divest our 90% ownership of EDSLan, a communication equipment distribution company located in Milan, Italy. EDSLan was part of our Network Integration segment. We recognized a loss related to the write down of the assets of EDSLan to their net realizable value in 2009.

On October 26, 2010, the Company sold all of the issued and outstanding capital stock of its wholly-owned

subsidiaries Source Photonics, Inc. and Source Photonics Santa Clara, Inc. Inc. (together “Source Photonics"). We

Table of Contents

recognized a gain of $37.5 million in 2010 on the sale of Source Photonics. We have reclassified the historical results of EDSLan and Source Photonics as discontinued operations in this Form 10-K for all periods presented. Accordingly, the related assets and liabilities of EDSLan and Source Photonics have been classified as assets and liabilities from discontinued operations in the Balance Sheet and their net income or loss has been classified as income or loss from discontinued operations. See Note 3 "Discontinued Operations" to the Financial Statements in Item 8 of this Form 10-K for further discussion.

Our business involves reliance on foreign-based offices. Several of our divisions, outside subcontractors and suppliers are located in foreign countries, including Argentina, Canada, Denmark, Finland, France, Germany, Israel, Italy, Japan, Korea, the Netherlands, Norway, Russia, Singapore, South Africa, Switzerland, Sweden, Taiwan, Turkey, and the United Kingdom. For the years ended December 31, 2010, 2009 and 2008, foreign revenues constituted 79%, 79% and 77%, respectively, of our total revenues. The majority of our foreign sales are to customers located in the European region, with remaining foreign sales primarily to customers in the Asia Pacific region.

In 2009, our customers took a more cautious approach in their capital expenditures, resulting in order delays, slowing deployments and lengthening sales cycles. In 2010, our customers resumed investments in their networks to meet the growth in consumer and enterprise use of high-bandwidth communications services. This improvement has positively impacted our revenues and operating results.

During 2010, we substantially improved the Balance Sheet primarily through the sale of Source Photonics which provided net proceeds of $110.5 million and eliminated $32.9 million in short-term debt. As demand for our products and services recovered in 2010 after a weak 2009, we grew revenues by 9% and brought the operating margin from a negative 2% in 2009 to 5% in 2010 with six of our seven business units delivering operating income and corporate expenses reduced by 21%. At the end of 2010, we had $156.9 million in cash and cash equivalents, short term marketable securities and restricted time deposits, $18.0 million in short-term debt, and $176.5 million in U.S. federal net operating loss carryforwards. We may divest of additional business units in 2011 and expect to reinvest some or all of our cash reserves in the near future in expansion of, or acquisitions within, our existing business units, acquisitions of additional business units, or repurchases of our common stock.

Critical Accounting Policies

Our discussion and analysis of the Company's financial condition and results of operations are based upon the financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). We follow accounting standards set by the Financial Accounting Standards Board ("FASB") to ensure we consistently report our financial condition, results of operations, and cash flows in conformity with GAAP. References to GAAP issued by the FASB in this Form 10-K is to the FASB Accounting Standards of Codification ("ASC").

The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We believe that the estimates, assumptions and judgments involved in the accounting policies described below have the greatest potential impact on our financial statements, so we consider these to be our critical accounting policies. Because of the uncertainty inherent in these matters, actual results could differ from the estimates we use in applying the critical accounting policies. Certain of these critical accounting policies affect working capital account balances, including the policies for revenue recognition, allowance for doubtful accounts, inventory reserves and income taxes. These policies require that we make estimates in the preparation of our financial statements as of a given date.

Within the context of these critical accounting policies, we are not currently aware of any reasonably likely events or circumstances that would result in materially different amounts being reported.

Revenue Recognition

Table of Contents

the contingencies have been satisfied or the contingent period has lapsed. For sales to distributors, we generally recognize revenue when product is sold to the distributor rather than when the product is sold by the distributor to the end user. In certain circumstances, distributors have limited rights of return, including stock rotation rights, and/or are entitled to price protection, where a rebate credit may be provided to the customer if MRV lowers its price on products held in the distributor's inventory. MRV estimates and establishes allowances for expected future product returns and credits in accordance with ASC 605. We record a reduction in revenue for estimated future product returns and future credits to be issued to the customer in the period in which revenues are recognized, and for future credits to be issued in relation to price protection at the time we make changes to our distributor price book. We monitor product returns and potential price adjustments on an ongoing basis and estimate future returns and credits based on historical sales returns, analysis of credit memo data, and other factors known at the time of revenue recognition.

Arrangements with customers may include multiple deliverables involving combinations of equipment, services and software. In accordance with ASC 605-25 Multiple-Element Arrangements, the entire fee from the arrangement is allocated to each respective element based on its relative fair value and recognized when revenue recognition criteria for each element is met. Fair value for each element is established based on the sales price charged when the same element is sold separately. If multiple element arrangements include software or software related elements, we apply the provisions of ASC 985- Software to the software and software related elements, or to the entire arrangement if the software is essential to the functionality of the non-software elements.

MRV generally warrants its products against defects in materials and workmanship for one to two year periods. The estimated cost of warranty obligations and sales returns and other allowances are recognized at the time of revenue recognition based on contract terms and prior claims experience.

Allowance for Doubtful Accounts

We make ongoing estimates relating to the collectability of our accounts receivable and maintain a reserve for estimated losses resulting from the inability of customers to meet their financial obligations to us. In determining the amount of the reserve, we consider our historical level of credit losses and make judgments about the creditworthiness of significant customers based on ongoing credit evaluations. Because we cannot precisely predict future changes in the financial stability of our customers, actual future losses from uncollectible accounts may differ from our estimates. If the financial condition of our customers deteriorate, resulting in their inability to make payments, a larger reserve may be required. In the event we determine that a change in the allowance is appropriate, we would record a credit or a charge to selling, general and administrative expense in the period in which we make such a determination.

Inventory Reserves

We make ongoing estimates relating to the market value of inventories, based upon our assumptions about future demand and market conditions. If we estimate that the net realizable value of our inventory is less than the cost of the inventory recorded on our books, we record an adjustment to the cost basis equal to the difference between the cost of the inventory and the estimated net realizable market value. This adjustment is recorded as a charge to cost of sales. If changes in market conditions result in reductions in the estimated market value of our inventory below previous estimates, we would make further adjustments in the period in which we make such a determination and record a charge to cost of sales. The reserve includes estimates for excess quantities and obsolete inventory. If changes in our projections of current demand indicate that the reserve should be higher or lower, the change in the reserve is recorded as a charge or credit to cost of sales.

Goodwill and Other Intangibles

Goodwill represents the excess purchase price over amounts assigned to tangible or identifiable intangible assets acquired and liabilities assumed from our acquisitions. In accordance with ASC 350 Intangibles—Goodwill and Other, we do not amortize goodwill and intangible assets with indefinite lives, but instead measure these assets for impairment at least annually. We also test goodwill for impairment between annual tests if an event occurs or circumstances change that could potentially reduce the fair value of the reporting unit below its carrying value.

Our annual assessment considers economic conditions and trends, estimated future operating results, and anticipated future economic conditions. We determine the fair value of each reporting unit using a discounted cash flow based valuation methodology. To validate reasonableness of the valuation, we reconcile the sum of the fair values across all reporting units to the Company's market capitalization as of the valuation date. The first step is to compare the fair value of the reporting unit with the unit's carrying amount, including goodwill. If this test indicates that the fair value is less than the carrying value, then step two is required to compare the implied fair value of the reporting unit's goodwill with the carrying amount of the reporting unit's goodwill. A non-cash goodwill impairment charge would have the effect of decreasing our earnings or increasing our losses in such period. See Note 4 "Goodwill" to the Financial

Table of Contents

Statements in Item 8 of this Form 10-K for further discussion.

Share-Based Compensation

We determine the fair value of stock options and warrants using the Black-Scholes valuation model as permitted under ASC 718 Compensation — Stock Compensation. The assumptions used in calculating the fair value of share-based payment awards represent our best estimates. Our estimates may be impacted by certain variables including stock price volatility, employee stock option exercise behaviors, additional stock option grants, estimates of forfeitures, and the related income tax impact. See Note 13 "Share-Based Compensation" to the Financial Statements in Item 8 of this Form 10-K for further discussion.

Income Taxes

As part of the process of preparing our financial statements, we estimate the income taxes in each of the jurisdictions in which we operate. This process involves estimating the current income tax exposure together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for income tax and accounting purposes. These differences result in deferred income tax assets and liabilities, which are included in our Balance Sheets. We assess the likelihood that our deferred income tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not likely, we establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we include an expense within the income tax provision in the Statements of Operations.

We utilize significant management judgment to determine the provision for income taxes, deferred income tax assets and liabilities, including uncertain tax positions, and any valuation allowance recorded against net deferred income tax assets. Management periodically evaluates the deferred income tax assets as to whether it is likely that the deferred income tax assets will be realized. We write down the deferred income tax asset at the time we determine the asset is not likely to be realized.

Recently Issued Accounting Standards

For a discussion of recently issued accounting standards relevant to our financial performance, see Note 2 to the Financial Statements included in Item 8 of this Form 10-K.

Currency Rate Fluctuations

Changes in the relative values of non-U.S. currencies to the U.S. dollar affect our results. We conduct a significant portion of our business in foreign currencies, including the euro, the Swiss franc, the Swedish krona and the Israeli new shekel. For the year ended December 31, 2010, approximately 69% of revenues and 41% of operating expenses were incurred at subsidiaries with a functional currency other than the U.S. dollar. In general, these currencies, excluding the Swiss franc, were weaker against the U.S. dollar for the year ended December 31, 2010, compared to the year ended December 31, 2009, so revenues and expenses in these countries translated into fewer dollars than they would have in the prior period. The Swiss franc was stronger against the U.S. dollar for the year ended December 31, 2010 compared to the year ended December 31, 2009, so revenues and expenses at our Swiss subsidiaries translated into more dollars than they would have in the prior period. Additional discussion of foreign currency risk and other market risks is included in Item 7A "Quantitative and Qualitative Disclosures About Market Risk" of this Form 10-K.

(2)	Percentage information in constant currencies in the table above and in the text below excludes the effect of foreign currency translation on reported results. Constant currency results were calculated by translating the current year results at prior year average exchange rates.

Revenues for 2010 increased $21.6 million, or 9%, due primarily to a $20.0 million, or 19%, increase in Network Equipment, and a $7.9 million, or 6%, increase in Network Integration, partially offset by a $6.0 million, or 82%, increase in intersegment revenues from the Network Equipment group to the Network Integration group, which are eliminated in consolidation. Revenue would have been $3.4 million higher in 2010 had foreign currency exchange rates remained the same as they were in 2009, primarily in the Network Integration group.

Network Equipment Group. Revenue, including intersegment revenue, generated from the Network Equipment group increased $20.0 million, or 19%, in 2010, with year-over-year growth each quarter. Our OCS division had 19% growth led by the Americas regions. The growth was led by sales of our Media Cross Connect and OptiSwitch product lines, which grew by 109% and 93%, respectively. Media Cross Connect sales benefited from the introduction of our new High Speed Media Cross Connect chasis with a 10.7 Gbps backplane. The growth in OptiSwitch was driven by the substantial increase in mobile backhaul investments during 2010 as well as by the growth of Carrier Ethernet in the mobile backhaul market. CES, our Swiss aerospace and defense unit, grew revenue by 18%. Revenue would have been $1.3 million lower in 2010 had foreign currency exchange rates remained the same as they were in 2009.

Network Integration Group. Revenue generated from the Network Integration group increased $7.9 million, or 6% in 2010. Revenue growth was driven by a $7.9 million increase at Alcadon, primarily due to strong sales of OptiSwitch, a $3.8 increase at Tecnonet, and a $2.3 million increase at Interdata. These revenue increases were partially offset by a $6.0 million decrease in revenue at TurnKey, our Swiss Network Integration company, which had two large customer projects in 2009 which did not continue in 2010. All revenue in the Network Integration group was generated in Europe. Revenue would have been $4.7 million higher in 2010 had foreign currency exchange rates remained the same as they were in 2009.

(2)	Percentage information in constant currencies in the table above and in the text below excludes the effect of foreign currency translation on reported results. Constant currency results were calculated by translating the current year results at prior year average exchange rates.

Gross profit increased $14.5 million due to the $21.6 million increase in revenues combined with the increase in average gross margin from 41% to 43%. The improvement in average gross margins was due to an improvement in gross margins in the Network Equipment group combined with the increase in the proportion of revenues contributed by the Network Equipment group, and the increase in intersegment sales, partially offset by a decrease in gross margins in the Network Integration group. Foreign currency exchange rates did not have a material impact on the consolidated gross profit as the impact in the Network Equipment group was offset by the impact in the Network Integration group. Gross profit reflects share-based compensation in cost of sales of $49,000 and $0.1 million in 2010 and 2009, respectively.

Network Equipment Group. The $14.8 million, or 26% increase, in gross profit for the Network Equipment group was due to a 19% increase in revenue combined with an improvement in average gross margin from 54% to 57%. The improvement in average gross margin is due to improved margins at both OCS and CES. OCS margins improved due to a favorable change in product mix as well as an increase in the proportion of revenues from the Americas regions. CES margins improved due to an increase in service revenues and a decrease in inventory reserve charges. Gross profit would have been $0.8 million lower in 2010 had foreign currency exchange rates remained the same as they were in 2009. Gross profit reflects share-based compensation in cost of sales of $47,500 and $0.1 million in 2010 and 2009, respectively.

Network Integration Group. Gross profit for the Network Integration group increased $0.2 million. The increase was driven by a 6% increase in revenues, partially offset by a decline in average gross margins from 29% to 27% and unfavorable changes in the exchange rate. We experienced a slight decline in gross margins from services at several business units where we increased service related headcount as part of our effort to increase the services we offer to our customers. We also experienced some declines in product gross margins at Alcadon where certain large volume, lower margin projects helped lead to the $7.9 million increase in revenues. Gross profit would have been $0.8 million higher in 2010 had foreign currency exchange rates remained the same as they were in 2009. The Network Integration group did not have share-based compensation in cost of sales in either year.

Operating expenses were $100.2 million, or 38% of revenues, in 2010 compared to $102.0 million, or 42% of revenues, in 2009. Operating expenses in 2010 were $1.9 million lower than they were in 2009. This decrease occurred primarily in Corporate unallocated operating expenses which declined by $3.1 million due to general cost cutting efforts as well as $2.1 million of expenses related to the proxy contest in 2009, partially offset by $0.9 million of expense in 2010 related to the separation of our former chief executive officer and relatively higher compensation costs of our new chief executive officer. Operating expenses would have been $0.3 million lower in 2010 had foreign currency exchange rates remained the same as they were in 2009. Product development and engineering expenses included share-based compensation of $0.1 million and $0.3 million in 2010 and 2009, respectively. Selling, general and administrative expenses included share-based compensation of $1.6 million and $1.1 million in 2010 and 2009, respectively.

Network Equipment Group. Operating expenses in the Network Equipment group for 2010 were $59.7 million, or 47% of revenues, compared to $58.6 million, or 55% of revenues in 2009. The $1.1 million, or 2%, increase was due to a 5% increase in operating expenses at OCS partially offset by a 7% decrease at CES. The decrease in operating expenses at CES is primarily due to the result of a reduction in previously accrued bonuses to employees terminated in 2010. Operating expenses would have been $0.6 million lower in 2010 had foreign currency exchange rates remained the same as they were in 2009. Product development and engineering expenses included share-based compensation of $0.1 million and $0.3 million in 2010 and 2009, respectively. Selling, general and administrative expenses included share-based compensation of $0.3 million and $0.5 million in 2010 and 2009, respectively.

Network Integration Group. Operating expenses in the Network Integration group for 2010 were $28.9 million, or 19% of revenues, compared to $27.1 million, or 19% of revenues in 2009. The $1.8 million, or 7%, increase in operating expense came primarily from TurnKey, which had a $0.3 million reversal of an accrual in 2009 and an increase in sales and marketing expenses in 2010. We also recognized a $1.2 million charge in 2010 related to the impairment of goodwill at Turnkey. We were generally successful at increasing revenue at Alcadon, Interdata and Tecnonet without a corresponding increase in operating expenses. Operating expenses would have been $0.3 million higher in 2010 had foreign currency exchange rates remained the same as they were in 2009. The Network Integration group did not have significant share-based compensation in product development and engineering costs in either year. Selling, general and administrative expenses included share-based compensation of $17,000 in 2010. There was no share-based compensation included in selling general and administrative expenses in 2009.

The 15% growth in gross profit and 2% decrease in operating expenses allowed us to move from a $3.8 million operating loss in 2009 to $12.6 million of operating income in 2010, representing operating margin of 5%. Our operating income would have been $0.1 million higher in 2010 had foreign currency exchange rates remained the same as they were in 2009. Operating income (loss) included share-based compensation expense of $1.7 million and $1.5 million in 2010 and 2009, respectively.

Network Equipment Group. The Network Equipment group reported operating income of $12.2 million for 2010, compared to an operating loss of $1.5 million for 2009. OCS was able to grow revenue by 19%, improve gross margins, and hold operating expenses to 5% growth. CES was able to grow revenue by 18%, improve gross margins, and decrease operating expenses by 7%. Appointech, though representing only 2% of network equipment revenue, delivered a 50% increase in revenue with 28% operating margins. The $13.7 million improvement in operating income was due to the $14.8 million increase in gross profit, partially offset by a $1.1 million increase in operating expenses. Operating income would have been $0.1 million lower in 2010 had foreign currency exchange rates remained the same as they were in 2009.

Network Integration Group. The Network Integration group reported operating income of $12.2 million for 2010, compared to operating income of $13.8 million for 2009. The $1.6 million decline was due to a $1.8 million increase in operating expenses, partially offset by a $0.2 million increase in gross profit. Operating income would have been $0.2 million higher in 2010 had foreign currency exchange rates remained the same as they were in 2009.

Interest Expense and Other Income, Net

Interest expense was $1.0 million in 2010 compared to $1.3 million in 2009 reflecting a reduction in our average interest rate. Other income, net, principally includes interest income on cash, cash equivalents and investments and gains (losses) on foreign currency transactions. We recognized a loss of $2.8 million on foreign currency transactions in 2010 compared to a $0.4 million loss in 2009. Other income for 2009 includes a $20.5 million gain realized upon the settlement we negotiated with certain former Fiberxon stockholders of the $30.0 million net deferred consideration payable arising from the 2007 acquisition of Fiberxon. In 2010, we recognized an additional gain of $0.5 million as we agreed to settlements with additional former Fiberxon stockholders. Other income for 2009 also includes a $3.5 million gain on the sale of a cost-basis investment in Dune Networks. Interest income was $0.3 million in 2010, $0.2 million lower than 2009, due to lower average investment balances and lower interest rates.

Provision for Income Taxes

The provision for income taxes was $2.7 million in 2010 and $4.2 million in 2009. Income tax expense fluctuates based on the amount of pre-tax income generated in the various jurisdictions where we conduct operations and pay income tax. The decrease in provision for income taxes during 2010 is primarily due to a $3.9 million release of valuation allowances against deferred tax assets related to net operating loss carryforwards of OCS in certain foreign jurisdictions, partially offset by higher taxes at CES, Alcadon, Interdata and Tecnonet due to higher pre-tax income.

Tax Loss Carry Forwards

As of December 31, 2010, we had NOLs of $176.5 million, $156.8 million, and $88.7 million for federal, state, and foreign income tax purposes, respectively. Under the Internal Revenue Code, if a corporation undergoes an "ownership change," the corporation's ability to use its pre-change NOLs, capital loss carry forwards and other pre-change tax attributes to offset its post-change income may be limited. An ownership change is generally defined as a greater than 50% change in its equity ownership by value over a three-year period. We may experience an ownership change in the future as a result of subsequent shifts in our stock ownership. If we were to trigger an ownership change in the future, our ability to use any NOLs and capital loss carry forwards existing at that time could be limited. As of December 31, 2010, the US federal and state NOLs had a full valuation allowance.

Discontinued Operations

Income from discontinued operations includes the results of operations of Source Photonics and EDSLan. We completed the sale of Source Photonics on October 26, 2010. The income from discontinued operations for 2010 includes a $37.5 million gain on sale of Source Photonics and the results of operations of Source Photonics through October 26, 2010. On December 24, 2009, we entered into an agreement to divest our 90% ownership of EDSLan. The loss from discontinued operations for 2009 includes a $3.8 million write-down of the net assets of EDSLan to net realizable value, and the results of operations of Source Photonics and EDSLan. For further discussion of discontinued operations, see Note 3 to the Financial Statements included in Item 8 of this Form 10-K.

Table of Contents

Revenues for 2009 decreased $21.0 million, or 17%, due primarily to a $21.0 million decrease in Network Equipment, and a $9.9 million, or 6%, decrease in Network Integration, partially offset by a $1.5 million decline in intersegment revenues from the Network Equipment group to the Network Integration group, which are eliminated in consolidation. Revenue would have been $8.6 million higher in 2009 had foreign currency exchange rates remained the same as they were in 2008, primarily in the Network Integration group.

Network Equipment Group. We experienced a decline in the market for our Network Equipment group's products during 2009 compared to 2008. The decline in the group's revenues, including intersegment revenues, of $21.0 million, or 17%, was experienced in all four quarters, across all regions and in most product categories. The exception was in CES, which had a 10% increase in revenues. Our most significant declines were in our LambdaDriver and out-of-band networking product lines. Our Fiber Driver and OptiSwitch product lines performed relatively well. Revenue would have been $0.2 million lower in 2009 had foreign currency exchange rates remained the same as they were in 2008.

The following table summarizes Network Equipment revenues by geographical region (dollars in thousands):

Total Network Equipment revenue	$	105,977	$	126,978	$	(21,001	)	(17	)%

Network Integration Group. The Network Integration group's revenues, including intersegment revenues, decreased $9.9 million, or 6% primarily due to the impact of changes in foreign currency exchange rates. Revenue would have been $8.8 million higher in 2009 had foreign currency exchange rates remained the same as they were in 2008. On a local currency basis, we experienced declines in revenues in our Scandinavian and Swiss businesses which were partially offset by gains at Tecnonet, our Italian subsidiary. All revenue in the Network Integration group was generated in Europe.

(2)	Percentage information in constant currencies in the table above and in the text below excludes the effect of foreign currency translation on reported results. Constant currency results were calculated by translating the current year results at prior year average exchange rates.

Gross profit declined $8.1 million due to the $29.4 million decline in revenues partially offset by the increase in average gross margin from 39% to 41%. The $8.1 million decrease was primarily due to a $10.7 million decrease in the Network Equipment group, partially offset by an improvement of $2.6 million in the Network Integration group. Gross profit would have been $3.1 million higher in 2009 had foreign currency exchange rates remained the same as they were in 2008. Gross profit reflects share-based compensation in cost of sales of $0.1 million and $0.2 million in 2009 and 2008, respectively.

Network Equipment Group. The $10.7 million, or 16% decrease, in gross profit for the Network Equipment group was due to a 17% decrease in revenue partially offset by an improvement in average gross margin from 53% to 54%. The improvement in average gross margin is due to an increase in the proportion of revenue coming from our Swiss aerospace and defense business, which has a higher gross margin than the remainder of our Network Equipment business. Gross profit reflects share-based compensation in cost of sales of $0.1 million and $0.1 million in 2009 and 2008, respectively.

Network Integration Group. Gross profit for the Network Integration group increased $2.6 million. The increase was driven by an improvement in average gross margins, partially offset by a 6% decline in revenues and unfavorable changes in the exchange rate. Average gross margin increased from 25% to 29%. The increase in gross margins in 2009 was the result of differences in the composition of the products and services sold in each period. Specifically, while gross margins were improved at each subsidiary, the most significant improvements came from Tecnonet, which has been successful in increasing the portion of its revenue coming from higher margin services. Gross profit would have been $3.1 million higher in 2009 had foreign currency exchange rates remained the same as they were in 2008. The Network Integration group did not have share-based compensation in cost of sales in either year.

(1)	Percentage information in constant currencies in the table above and in the text below excludes the effect of foreign currency translation on reported results. Constant currency results were calculated by translating the current year results at prior year average exchange rates.

Operating expenses were $102.0 million, or 42% of revenues, in 2009 compared to $118.6 million, or 44% of revenues, in 2008. The 2008 operating expenses include a goodwill impairment charge of $6.4 million. Excluding this charge, operating expenses in 2008 were $112.2 million, and operating expenses in 2009 were $10.2 million lower than they were in 2008. This decrease occurred across all operating segments and at corporate. The decrease in Corporate unallocated operating expenses is primarily due to a reduction in restatement related expenses partially offset by $2.1 million of expenses related to the proxy contest. Operating expenses would have been $2.5 million higher in 2009 had foreign currency exchange rates remained the same as they were in 2008. Product development and engineering expenses included share-based compensation of $0.3 million and $0.5 million in 2009 and 2008, respectively. Selling, general and administrative expenses included share-based compensation of $1.1 million and $1.8 million in 2009 and 2008, respectively.

Network Equipment Group. Operating expenses in the Network Equipment group for 2009 were $58.6 million, or 55% of revenues, compared to $68.9 million, or 54% of revenues in 2008. The $10.4 million, or 15%, decrease was attributable to the $6.4 million goodwill impairment charge in 2008 and to $4.0 million in cost reductions made in response to the decline in revenues. We reduced headcount, temporarily reduced pay, and cut back in other discretionary spending to achieve the reduction in expenses. Operating expenses would have been $0.1 million lower in 2009 had foreign currency exchange rates remained the same as they were in 2008. Product development and engineering expenses included share-based compensation of $0.3 million and $0.4 million in 2009 and 2008, respectively. Selling, general and administrative expenses included share-based compensation of $0.5 million and $0.8 million in 2009 and 2008, respectively.

Network Integration Group. Operating expenses in the Network Integration group for 2009 were $27.1 million, or 19% of revenues, compared to $31.9 million, or 21% of revenues in 2008. The $4.8 million, or 15%, decrease in operating expense came primarily from our Swedish subsidiary ($3.9 million) and our French subsidiary ($1.0 million). In the prior year, we recorded $1.8 million in additional compensation expense at our Swedish subsidiary to allow its management team to pay the taxes due on bonuses we paid them from 2002 to 2007. The remaining operating expense reductions were achieved through cost cutting measures in response to the weak economic environment during 2009. Operating expenses would have been $2.6 million higher in 2009 had foreign currency exchange rates remained the same as they were in 2008. The Network Integration group did not have significant share-based compensation in product development and engineering costs in either year. Selling, general and administrative expenses included share-based compensation of $0.3 million in 2008. The Network Integration group did not have significant share-based compensation in selling, general and administrative expenses in 2009.

(2)	Percentage information in constant currencies in the table above and in the text below excludes the effect of foreign currency translation on reported results. Constant currency results were calculated by translating the current year results at prior year average exchange rates.

The $3.8 million operating loss in 2009 represented 2% of revenues, compared to a $12.2 million operating loss, or 4% of revenues, in 2008. Excluding the goodwill impairment charges in 2008 of $6.4 million, our operating loss was $2.0 million lower in 2009 than in 2008. Our operating loss would have been $0.6 million less in 2009 had foreign currency exchange rates remained the same as they were in 2008. Operating loss included share-based compensation expense of $1.5 million and $2.4 million in 2009 and 2008, respectively.

Network Equipment Group. The Network Equipment group reported an operating loss of $1.5 million for 2009, compared to an operating loss of $1.1 million for 2008. The increase in operating loss was due to the $10.7 million decline in gross profits mostly offset by a $10.4 million decrease in operating expenses. The effect of currency fluctuations did not have a significant impact on the year-over-year change on operating loss.

Network Integration Group. The Network Integration group reported operating income of $13.8 million for 2009, compared to operating income of $6.4 million for 2008. The $7.4 million improvement was due to the combination of a $2.6 million improvement in gross margins and a $4.8 million decrease in operating expenses. Operating income would have been $0.5 million higher in 2009 had foreign currency exchange rates remained the same as they were in 2008.

Interest Expense and Other Income, Net

Interest expense was $1.3 million in 2009 compared to $2.2 million in 2008, reflecting a reduction in our average interest rate partially offset by an increase in debt. Included in non-operating income is a $20.5 million gain realized in the fourth quarter of 2009 upon the settlement we negotiated with certain former Fiberxon stockholders of the $30.0 million net deferred consideration payable arising from the 2007 acquisition of Fiberxon. We also realized a $3.5 million gain on the sale of a cost-basis investment in Dune Networks. In the prior year, we realized a $2.6 million gain on the sale of an investment. Interest income was $0.5 million in 2009 compared to $1.8 million in 2008, due to lower average investment balances and lower interest rates. Foreign currency transactions resulted in losses of $0.4 million in 2009 compared to a $0.7 million loss in 2008.

Provision for Income Taxes

The provision for income taxes was $4.2 million in 2009 and $3.2 million in 2008. Income tax expense fluctuates based on the amount of pre-tax income generated in the various jurisdictions where we conduct operations and pay income tax. The increase in provision for income taxes during 2009 is primarily due to a $1.2 million increase in the Network Integration group, which had a 21% increase in pre-tax income.

Tax Loss Carry Forwards

As of December 31, 2009, we had NOLs of $228.6 million, $142.8 million, and $96.7 million for federal, state, and foreign income tax purposes, respectively.

Discontinued Operations

Income from discontinued operations includes the results of operations of Source Photonics and EDSLan. We completed the sale of Source Photonics on October 26, 2010. On December 24, 2009, we entered into an agreement to divest our 90% ownership of EDSLan. The loss from discontinued operations for 2009 includes a $3.8 million write-down of the net assets of EDSLan to net realizable value, and the results of operations of Source Photonics and EDSLan. The loss from discontinued operations for 2008 includes the results of operations of Source Photonics and EDSLan, including a $93.9 million goodwill impairment charge. For further discussion of discontinued operations, see Note 3 to the Financial Statements included in Item 8 of this Form 10-K.

Liquidity and Capital Resources

Our three primary sources of cash are cash receipts from customers, debt financing, and sales of invested assets. Historically, we have satisfied short and long-term obligations through cash generated from these sources and we expect that this trend will continue. Notably, in 2010 we received cash proceeds from the sale of Source Photonics of $110.5 million, net of transaction related expenses, $11.3 million from the sale of EDSLan, and $3.7 million from the sale of our cost-basis investment in Dune Networks, Inc. We believe that cash on hand and cash flows from operations will be sufficient to satisfy current operating needs, capital expenditures, and product development and engineering requirements for at least the next 12 months.

We operate our business through several subsidiaries in our two operating segments. Each subsidiary maintains some level of cash and is able to meet its cash needs primarily through cash receipts from customers. In recent years, we have funded our corporate expenses through a combination of the use of cash reserves and short-term investments at corporate, cash remitted from our subsidiaries, and the sale of investments in unconsolidated entities and subsidiaries. We currently do not have any debt at the corporate level. One of our subsidiaries, Tecnonet, maintains short-term lines of credit primarily secured by accounts receivable to fund its working capital needs. EDSLan and Source Photonics, which are presented as discontinued operations, also borrowed under short-term lines of credit and had outstanding balances of $9.6 million and $51.2 million, respectively, at December 31, 2009.

The following table illustrates our contractual obligations as of December 31, 2010 (in thousands):


Contractual Obligations	Total		Less than 1 Year		1 - 3 Years		3 - 5 Years		After 5 Years
Short-term debt	$	18,036	$	18,036	$	—	$	—	$	—

We expect to have sufficient cash and cash flow to meet our short-term and our long-term obligations shown in the table above. Our operating leases consist primarily of leases for buildings worldwide from which we conduct our business. Purchase commitments consist primarily of purchase orders for components used to build finished goods inventory. The deferred consideration payable arose from the acquisition agreement for Fiberxon, a company we acquired in July 2007. The accrual amount was $8.0 million at December 31, 2009 and was reduced during 2010 to $4.6 million through payments of $2.9 million and a gain of $0.5 million recognized upon settlement with additional former stockholders of Fiberxon.

Our cash flow from operations consists of cash collected from customers and payments made to vendors and employees. Our cash flow in a particular period is determined by our profitability, adjusted for non-cash items, and changes in working capital. During periods of growth, we require more working capital to fund the cash conversion cycle, which represents the period of time from when we purchase inventory, and pay for labor and other costs, until that inventory is converted to product, sold, and payment is received from our customers. In addition to changes in accounts receivable, inventory and accounts payable, our cash flow from operations is impacted from the increase or decrease in other current assets and current liabilities, including prepaid expenses and accrued liabilities.

The increase in working capital from continuing operations is primarily due to the cash proceeds from the sale of Source Photonics.

The following table summarizes our cash flow from operations from our Statements of Cash Flows (in thousands):


Years ended December 31:	2010			2009

Cash Flows Related to Operating Activities. Our cash used in operations included an increase in accounts receivable of $26.0 million, an increase in inventory of $20.3 million, a decrease in accrued liabilities of $2.0 million and changes in other working capital accounts of $18.3 million. Source Photonics contributed $17.5 million of the increase in accounts receivable and $8.8 million of the increase in inventory due to a substantial increase in its revenue compared to 2009. The remaining increase in accounts receivable and inventory relates to the increase in revenues and the timing of shipments and collections. The decrease in accrued liabilities primarily relates to the payment of deferred consideration payable settlements to former Fiberxon shareholders. The changes in other working capital accounts includes the payment for a prepaid license at Source Photonics of $8.6 million related to our settlement with Finisar. Our sources of operating cash flow included net income of $50.8 million less the gain on investing activities of $37.4 million, non-cash expenses of $10.0 million, and an increase in accounts payable of $16.3 million, primarily at Source Photonics, related to the increase in revenue.

We sold Source Photonics in October 2010. We believe this transaction also strengthened our cash and debt position by providing cash proceeds of approximately $110.5 million, net of transaction related expenses, and by eliminating $32.9 million of Source Photonics debt from our balance sheet. Source Photonics used cash in operating activities of $13.6 million and $12.3 million in 2010 and 2009, respectively, and provided cash from operating activities of $2.2 million in 2008.

We may seek to obtain additional debt or equity financing if we believe it appropriate. If we seek financing through issuance of additional equity securities, we may limit our ability to use available net operating loss and capital loss carryforwards. Under the Internal Revenue Code, if a corporation undergoes an "ownership change," the corporation's ability to use its pre-change NOLs, capital loss carry forwards and other pre-change tax attributes to offset its post-change income may be limited. An ownership change is generally defined as a greater than 50% change in its equity ownership by value over a three-year period. For additional information on the potential limitations on our use of net operating loss and capital loss carry forwards available to us at December 31, 2010, see the risk factor Item 1A of this Form 10-K under the caption "Our ability to utilize our NOLs and certain other tax attributes may be limited." Our future capital requirements will depend on many factors, including our rate of revenue growth, the timing and extent of spending to support development of new products and the expansion of sales and marketing efforts, the timing of new product introductions and enhancements to existing products, and the market acceptance of our products.

Off-Balance Sheet Arrangements

We do not have transactions, arrangements or relationships with unconsolidated entities that are reasonably likely to affect our liquidity or capital resources. We do not have special purpose or limited purpose entities that provided off-balance sheet financing, liquidity or market or credit risk support, or that engaged in leasing, hedging, research and development services, or other relationships that expose us to liability that is not reflected on the face of the financials.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Market risk represents the risk of loss that may impact our Consolidated Financial Statements through adverse changes in financial market prices and rates and inflation. Our market risk exposure results primarily from fluctuations in foreign exchange and interest rates. We manage our exposure to these market risks through our regular operating and financing activities and, in certain instances, through the use of derivative financial instruments. These derivative instruments are used to manage risks of volatility in interest and foreign exchange rate movements on certain assets, liabilities or anticipated transactions and create a relationship in which gains or losses on derivative instruments are expected to counter-balance the losses or gains on the assets, liabilities or anticipated transactions exposed to such market risks.

Interest Rates. Our investments, short-term borrowings and long-term obligations expose us to interest rate fluctuations. Our cash and short-term investments are subject to limited interest rate risk, and are primarily maintained in money market funds and bank deposits. Our variable-rate short-term borrowings are also subject to limited interest rate risk because of their short-term maturities. Through certain foreign offices, and from time to time, we enter into interest rate swap contracts. As of December 31, 2010, we did not have any interest rate swap contracts outstanding. The economic purpose of entering into interest rate swap contracts is to protect our variable interest debt from significant interest rate fluctuations.

Foreign Exchange Rates. We operate on an international basis with a significant portion of our revenues and expenses transacted in currencies other than the U.S. dollar. Fluctuation in the value of these foreign currencies affects our results and will cause U.S. dollar translation of such currencies to vary from one period to another. We cannot predict the effect of exchange rate fluctuations upon future operating results. However, because we have revenues and expenses in each of these foreign currencies, the effect on our results of operations from currency fluctuations is reduced.

Through certain foreign offices, and from time to time, we enter into foreign exchange contracts in an effort to minimize the currency exchange risk related to purchase commitments denominated in foreign currencies. These contracts cover periods commensurate with known or expected exposures, generally less than three months. As of December 31, 2010, we did not have any foreign exchange contracts outstanding.

Certain assets, including certain bank accounts and accounts receivables of some of our business units, exist in currencies other than the functional currency of the related business units, which are sensitive to foreign currency exchange rate fluctuations. These principally include the U.S. dollar, the euro, the Swedish krona, the Swiss franc, the Taiwan dollar, and the Israeli new shekel. Additionally, Tecnonet, which has a functional currency of the euro, has certain of its lines are credit denominated in U.S. dollars. When these transactions are settled in a currency other than the functional currency, we recognize a foreign currency transaction gain or loss.

When we translate the financial position and results of operations of subsidiaries with functional currencies other than the U.S. dollar, we recognize a translation gain or loss in other comprehensive income. Approximately 65% of our cost of sales and operating expenses are reported by these subsidiaries. These currencies were generally weaker against the U.S. dollar for the year ended December 31, 2010 compared to the same period last year, so revenues and expenses in these countries translated into fewer dollars than they would have in 2009. For 2010, we had approximately:


•	$95.4 million in cost of goods and operating expenses recorded in euros;


•	$21.1 million in cost of goods and operating expenses recorded in Swedish kronor;


•	$30.6 million in cost of goods and operating expenses recorded in Swiss francs; and


•	$2.1 million in cost of goods and operating expenses recorded in Taiwan dollars;

Had rates of these various foreign currencies been 10% higher relative to the U.S. dollar during 2010, our costs would have increased to approximately:


•	$104.9 million in cost of goods and operating expenses recorded in euros;


•	$23.2 million in cost of goods and operating expenses recorded in Swedish kronor;


•	$33.7 million in cost of goods and operating expenses recorded in Swiss francs; and


•	$2.4 million in cost of goods and operating expenses recorded in Taiwan dollars;

1. Description of Business and Basis of Presentation

Description of Business

MRV Communications, Inc. ("MRV" or "the Company"), a Delaware corporation, is a global supplier of communications solutions to telecommunications service providers, enterprises and governments throughout the world. MRV's products enable customers to provide high-bandwidth data and video services and mobile communications services more efficiently and cost effectively. The Company markets and sells its products worldwide, through a variety of channels, which include a dedicated direct sales force, manufacturers' representatives, value-added-resellers, distributors and systems integrators. MRV conducts its business along two principal segments: the Network Equipment group and the Network Integration group. MRV's Network Equipment group designs, manufactures and sells equipment used by commercial customers, governments, aerospace, defense, and telecommunications service providers. Products include switches, routers, physical layer products and out-of-band management products, specialized networking products and other applications including voice and cellular communication. The Europe-based Network Integration segment provides network system design, integration and distribution services that include products manufactured by third-party vendors as well as products developed and manufactured by the Network Equipment group.

Basis of Presentation

MRV's fiscal year is based on the calendar year ending on December 31. The accompanying financial statements include the accounts of MRV and its subsidiaries required to be consolidated in accordance with the Accounting Standards Codification, or ASC, 810-10 Consolidations ("ASC 810"). All significant intercompany transactions and accounts have been eliminated. MRV consolidates the financial results of less than majority-owned subsidiaries when it has effective control, voting control or has provided the entity's working capital. When others invest in these enterprises reducing its voting control below 50%, MRV discontinues consolidation and uses the cost or equity method of accounting for these investments, unless otherwise required by ASC 810. As of December 31, 2010, all of the Companies subsidiaries were wholly-owned.

On December 24, 2009, the Company entered into an agreement to divest its 90% ownership in EDSLan, a communication equipment distribution company located in Milan, Italy, that was part of the Network Integration segment. On October 26, 2010, the Company sold all of the issued and outstanding capital stock of its wholly-owned subsidiaries Source Photonics, Inc. and Source Photonics Santa Clara, Inc. (together “Source Photonics"). The historical financial results of EDSLan and Source Photonics have been reclassified as discontinued operations for all periods presented in this Form 10-K. Accordingly, the related assets and liabilities of EDSLan and Source Photonics have been classified as assets and liabilities from discontinued operations in the Consolidated Balance Sheet. Cash flows from discontinued operations are presented combined with the cash flows from continuing operations in the accompanying Consolidated Statement of Cash Flows. See Note 3 "Discontinued Operations" for further discussion.

2. Summary of Significant Accounting Policies

Foreign Currency

Transactions originally denominated in other currencies are converted into functional currencies in accordance with ASC 830 Foreign Currency Matters. Increases or decreases in the expected amount of cash flows upon settlement of the transaction caused by changes in exchange rates are recorded as foreign currency gains and losses and are included in other income, net.

For foreign operations with the local currency as the functional currency, assets and liabilities are translated from the local currencies into U.S. dollars at the exchange rate prevailing at the balance sheet date. Revenues, expenses and cash flows are translated at weighted average exchange rates for the period to approximate translation at the exchange rate prevailing at the dates those elements are recognized in the financial statements. Translation adjustments resulting from the process of translating the local currency financial statements into U.S. dollars are included in determining comprehensive income or loss.

Revenue Recognition

MRV's major revenue-generating products consist of switches and routers, console management, physical layer products, and fiber optic components. MRV generally recognizes product revenue, net of sales discounts, returns and allowances, in accordance with ASC 605 Revenue Recognition, when persuasive evidence of an arrangement exists, delivery has occurred and all significant contractual obligations have been satisfied, the fee is fixed or determinable and collection is considered reasonably assured. Products are generally shipped "FOB shipping point," with no right of return and revenue is recognized upon shipment. If revenue is to be recognized upon delivery, such delivery date is tracked through information provided by the third party shipping company the Company uses to deliver the product to the customer. Sales of services and system support are deferred and recognized ratably over the contract period in accordance with ASC 605-20 Services. Sales to end customers with contingencies, such as rights of return, rotation rights, conditional acceptance provisions and price protection, are infrequent and insignificant and are deferred until the contingencies have been satisfied or the contingent period has lapsed. For sales to distributors, the Company generally recognizes revenue when product is sold to the distributor rather than when the product is sold by the distributor to the end user. In certain circumstances, distributors have limited rights of return, including stock rotation rights, and/or are entitled to price protection, where a rebate credit may be provided to the customer if MRV lowers its price on products held in the distributor's inventory. MRV estimates and establishes allowances for expected future product returns and credits in accordance with ASC 605. The Company records a reduction in revenue for estimated future product returns and future credits to be issued to the customer in the period in which revenues are recognized, and for future credits to be issued in relation to price protection at the time changes are made to the distributor price book. The Company monitors product returns and potential price adjustments on an ongoing basis and estimates future returns and credits based on historical sales returns, analysis of credit memo data, and other factors known at the time of revenue recognition.

Arrangements with customers may include multiple deliverables involving combinations of equipment, services and software. In accordance with ASC 605-25 Multiple-Element Arrangements, the entire fee from the arrangement is allocated to each respective element based on its relative fair value and recognized when revenue recognition criteria for each element is met. Fair value for each element is established based on the sales price charged when the same element is sold separately. If multiple element arrangements include software or software related elements, the Company applies the provisions of ASC 985 Software to the software and software related elements, or to the entire arrangement if the software is essential to the functionality of the non-software elements.

Cash and Cash Equivalents

MRV treats highly liquid investments with an original maturity of 90 days or less as cash equivalents. Cash balances and investments are maintained in qualified financial institutions, and at various times, such amounts are in excess of federal insured limits.

Restricted Time Deposits

Restricted time deposits represent investments that are restricted as to withdrawal or use and are primarily in foreign subsidiaries. Restricted time deposits generally secure standby letters of credit, bank lines of credit, or bank loans. When investments in restricted time deposits are directly related to an underlying bank loan and the restricted funds will be used to repay the loans, the investment and the subsequent release of the restricted time deposit are treated as financing activities in the Company's Consolidated Statement of Cash Flows. The other investments in and releases of restricted time deposits are included in investing activities because the funds are invested in certificates of deposit.

Marketable Securities

MRV accounts for its marketable securities, which are available for sale, under the provisions of ASC 320-10 Accounting for Certain Investments in Debt and Equity Securities. The original cost of MRV's marketable securities approximated fair market value as of December 31, 2010 and 2009. Unrealized gains (losses) at December 31, 2010 and 2009 were $39,000 and $50,000, respectively. Proceeds from sales of marketable securities were $49.1 million,

Table of Contents

MRV Communications, Inc.

Notes to Consolidated Financial Statements (Continued)

December 31, 2010

$13.2 million, and $8.7 million for the years ended December 31, 2010 and 2009, and 2008, respectively. Marketable securities mature at various dates through 2011.

Marketable securities consisted of the following (in thousands):


December 31:	2010		2009
U.S. government issues	$	11,699	$	12,081
Corporate issues	1,775		5,798
Total	$	13,474	$	17,879

Concentration of Credit Risk, Accounts Receivable and Allowance for Doubtful Accounts

Financial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents placed with high credit quality institutions and accounts receivable due from customers. MRV evaluates the collectability of accounts receivable based on a combination of factors. If the Company becomes aware of a customer's inability to meet its financial obligations after a sale has occurred, the Company records an allowance to reduce the net receivable to the amount which is reasonably believed to be collected from the customer. For all other customers, the Company records allowances for doubtful accounts based on the length of time the receivables are past due, the current business environment, and historical experience. If the financial conditions of MRV's customers were to deteriorate or if economic conditions worsen, additional allowances may be required in the future.

The following table summarizes the changes in the allowance for doubtful accounts (in thousands):


	Balance at beginning of period		Charged to expense		Deductions		Effect of foreign currency exchange rates		Balance at end of period
December 31, 2008	$	4,004	507		(225	)	(171	)	$	4,115
December 31, 2009	$	4,115	(39	)	(332	)	48		$	3,792
December 31, 2010	$	3,792	367		(591	)	(54	)	$	3,514

As of December 31, 2010 and 2009, amounts due from Telecom Italia S.p.A., a Network Integration group customer, exceeded 10% of gross accounts receivables.

Inventories

Inventories are stated at the lower of cost or market and consist of material, labor and overhead. Cost is determined by the first in, first out method. If the Company estimates that the net realizable value is less than the cost of the inventory, an adjustment to the cost basis is recorded through a charge to cost of sales to reduce the carrying value to net realizable value. At each balance sheet date, MRV evaluates the ending inventories for excess quantities or obsolescence. This evaluation includes analysis of sales levels and projections of future demand. Based on this evaluation, the Company maintains reserves for excess and obsolete inventory and the inventory balances are reported net of reserves. If changes in the Company's projections of current demand indicate that the reserve should be higher or lower, the change in the reserve is recorded as a charge or credit to cost of sales.

Net inventories consisted of the following (in thousands):


December 31:	2010		2009
Raw materials	$	9,556	$	9,163
Work-in process	4,498		3,881

December 31, 2010	$	19,841	2,785	(3,620	)	(12	)	$	18,994

Property and Equipment

Property and equipment are stated at cost. Maintenance and repairs are charged to expense as incurred and the costs of additions and betterments that increase the useful lives of the assets are capitalized. When property or equipment are disposed of, the cost and related accumulated depreciation and amortization are removed from the accounts and any gain or loss is included in other income, net, in the accompanying Consolidated Statements of Operations.

Property and equipment consisted of the following (in thousands):


December 31:	2010			2009
Property and equipment, at cost:
Machinery and equipment	$	14,463		$	13,281
Computer hardware and software	14,838			13,812

Less — accumulated depreciation and amortization	(35,422		)	(33,380		)
Total	$	8,541		$	7,541

Depreciation is computed using the straight line method over the estimated useful lives of the related assets, as follows:


	Life (years)
Asset category	From	To
Machinery and equipment	1	10
Computer hardware and software	1	8
Leasehold improvements	1	12
Furniture and fixtures	1	15
Building	33	33

Depreciation expense for the years ended December 31, 2010, 2009 and 2008 was $2.5 million, $2.0 million, and $2.0 million, respectively.

December 31, 2010

Goodwill and Other Intangibles

In accordance with ASC 350 Intangibles — Goodwill and Other, goodwill and intangible assets with indefinite lives are not amortized, but instead are measured for impairment at least annually, or when events indicate that impairment exists. MRV's annual impairment review date is October 1. Reviews for impairment are performed at each of MRV's reporting units. Intangible assets that are determined to have definite lives are amortized over their useful lives. At December 31, 2010, the Company did not have any intangible assets other than goodwill on its Balance Sheets. See Note 4 "Goodwill" for further information.

Investments

MRV accounts for investments in unconsolidated entities in accordance with ASC 323 Investments — Equity Method and Joint Ventures. Unconsolidated investments, for which the Company does not have the ability to exercise significant influence over operating and financial policies, are accounted for under the cost method. The Company accounts for investments for which MRV has the ability to exercise significant influence in terms of operating and financial policies, under the equity method. All unconsolidated investments in which the Company owns greater than 20% of the voting stock are accounted for under the equity method.

Under the cost and equity method, a loss in value of an investment, which is deemed to be other than a temporary decline, is recognized. Evidence of a loss in value might include absence of an ability to recover the carrying amount of the investment or inability of the investee to sustain an earnings capacity, which would justify the carrying amount of the investment. There were no cost or equity method investments held as of December 31, 2010.

Impairment of Long-Lived Assets

MRV evaluates its long-term tangible assets, such as property and equipment and other long-term assets, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may be impaired. The Company takes into consideration events or changes such as product discontinuance, plant closures, product dispositions and history of operating losses or other changes in circumstances to indicate that the carrying amount may not be recoverable. The carrying value of an asset is considered impaired when the anticipated undiscounted cash flow from such asset is less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value. Fair market value is determined using the anticipated cash flows discounted at a rate based on our weighted average cost of capital, which represents the blended after-tax costs of debt and equity. There was no impairment loss on tangible assets of continuing operations during the three years ended December 31, 2010.

Fair Value of Financial Instruments

MRV's financial instruments, including cash and cash equivalents, restricted time deposits, short-term and long-term marketable securities, accounts receivable, accounts payable, accrued liabilities and short-term debt obligations are carried at cost, which approximates their fair market value. The fair value of long-term debt obligations is estimated based on current interest rates available for debt instruments with similar terms, degrees of risk and remaining maturities. The carrying values of these obligations approximate their fair values.

ASC 820-10 Fair Value Measurements defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. ASC 820-10 establishes a three-level hierarchy that prioritizes the use of observable inputs, such as quoted prices in active markets, and minimizes the use of unobservable inputs, to measure fair value. All of MRV's assets and liabilities that are measured at fair value are measured using the unadjusted quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date. MRV adopted the provisions of ASC 820-10, effective January 1, 2008, for its financial assets and liabilities and the adoption did not have a material impact on MRV's consolidated financial statements. Under this standard, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the "exit price") in an orderly transaction between market participants at the measurement date.

In determining the fair value of its financial assets and liabilities, the Company uses various valuation approaches. ASC 820-10 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available.

Table of Contents

MRV Communications, Inc.

Notes to Consolidated Financial Statements (Continued)

December 31, 2010

The Company's available-for-sale securities are comprised of U.S. government agencies' obligations and corporate debt securities and are valued using quoted market prices of recent transactions or are benchmarked to transactions of very similar securities which are considered Level 1 category items. There were no material re-measurements to fair value during the year ended December 31, 2010 of financial assets and liabilities that are not measured at fair value on a recurring basis.

Liability for Severance Pay

Under the laws of certain foreign jurisdictions, MRV is obligated to make severance payments to employees in those foreign jurisdictions on the basis of factors such as each employee's current salary and length of employment. The liability for severance pay is calculated as the amount that the Company would be required to pay if every employee were to separate as of the end of the period, and is recorded as part of other long-term liabilities.

Noncontrolling Interests

In accordance with ASC 810, the Company reports noncontrolling interests in subsidiaries as equity in the consolidated financial statements.

Cost of Sales

Cost of sales includes material, depreciation on fixed assets used in the manufacturing process, shipping costs, direct labor and overhead. For the year ended December 31, 2010, the portion of cost of sales related to service revenue was $31.4 million.

Product Development and Engineering

Product development and engineering costs are charged to expense as incurred.

Software Development Costs

In accordance with ASC 985-20 Accounting for the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed, development costs related to software products are expensed as incurred until the technological feasibility of the product has been established. Technological feasibility occurs when a working model is completed. After technological feasibility is established, additional costs are capitalized.

MRV believes its process for developing software is essentially completed concurrent with the establishment of technological feasibility, and, accordingly, no software development costs have been capitalized to date.

Sales and Marketing

Sales and marketing costs are charged to expense as incurred. For the years ended December 31, 2010, 2009 and 2008, advertising and trade show costs were $1.9 million, $1.7 million and $2.1 million, respectively.

Income Taxes

Deferred income tax assets and liabilities are computed based on the temporary differences between the financial statement and income tax bases of assets and liabilities using the statutory marginal income tax rate in effect for the years in which the differences are expected to reverse. Deferred income tax expenses or credits are based on the changes in the deferred income tax assets or liabilities from period to period. Penalties and interest, if imposed, related to income taxes would be included in the tax provision.

Net Income (Loss) Per Share

Basic net income (loss) per share attributable to MRV is computed using the weighted average number of shares of Common Stock outstanding during the period. Diluted net income (loss) per share attributable to MRV is computed using the weighted average number of shares of Common Stock and dilutive potential shares of Common Stock outstanding during the period. Dilutive potential shares of Common Stock primarily consist of stock options and restricted stock grants.

ASC 260-10 Earnings per Share, requires that employee equity share options, nonvested shares and similar equity instruments granted by MRV, be treated as potential shares of Common Stock outstanding in computing diluted

Table of Contents

MRV Communications, Inc.

Notes to Consolidated Financial Statements (Continued)

December 31, 2010

net income per share. Diluted shares outstanding include the dilutive effect of in-the-money options, calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service not yet recognized, and the amount of income tax benefits that would be realized and recorded in additional paid-in capital if the deduction for the award would reduce income taxes payable are assumed to be used to repurchase shares.

Outstanding stock options and warrants to purchase 1.1 million shares for the year 2008 were not included in the computation of diluted per share amounts because such stock options and warrants were considered anti-dilutive.

Share-Based Compensation

As discussed in Note 13 "Share-Based Compensation," the fair value of stock options and warrants are determined using the Black-Scholes valuation model. The assumptions used in calculating the fair value of share-based payment awards represent MRV's best estimates. Those estimates may be impacted by certain variables including stock price volatility, employee stock option exercise behaviors, additional stock option grants, estimates of forfeitures, and the related income tax impact. See Note 13 for a further discussion on share-based compensation and assumptions used.

Recently Issued Accounting Standards

In June 2009, the FASB issued ASC 810-10 Consolidations ("ASC 810-10") providing (a) guidance on identifying variable interest entities and determining whether such entities should be consolidated; (b) general consolidation guidance; and (c) guidance on the consolidation of entities controlled by contract. The determination of whether a reporting entity is required to consolidate another entity is based on, among other things, the other entity's purpose and design and the reporting entity's ability to direct the activities of the other entity that most significantly impacts the other entity's economic performance. ASC 810-10 became effective for the Company beginning January 1, 2010. The adoption of ASC 810-10 did not have a material impact on the Company's financial condition, results of operations or liquidity.

In June 2009, the FASB issued ASC 860 Transfers and Servicing ("ASC 860") which requires more information about transfers of financial assets, including securitization transactions, and where entities have continuing exposure to the risks related to transferred financial assets. ASC 860 is effective for interim and annual reporting periods ending after November 15, 2009 and was applied prospectively. MRV adopted the provisions of ASC 860 on January 1, 2010. The application of ASC 860 did not have a material impact on the Company's financial condition, results of operations or liquidity.

In October 2009, the FASB amended the guidance for ASC 605 Revenue Recognition. The amendments establish a hierarchy for determining the selling price of a deliverable in a multiple-element deliverable revenue arrangement. The selling price used for each deliverable will be based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. The amendments also replace the term "fair value" in the revenue allocation guidance with "selling price" to clarify that the allocation of revenue is based on entity-specific assumptions rather than assumptions of a marketplace participant. The amendments eliminate the residual method of allocation and require that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. The relative selling price method allocates any discount in the arrangement proportionally on the basis of the selling price of each deliverable. The amendments became effective for the Company prospectively for revenue arrangements entered into or materially modified beginning January 1, 2011. MRV believes that the adoption of this new standard may have a material effect on its financial position and results of operations.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions affecting the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

On December 24, 2009, the Company entered into an agreement to divest its 90% ownership of EDSLan, a communication equipment distribution company located in Milan, Italy. The purchase agreement provided for the following: a) the payment from EDSLan to MRV of a dividend of two million euro; b) the sale of the Company's shares of EDSLan for six million euro; c) payment by the buyers of 250,000 euros of the investment banker's fees; and d) the cancellation of a put option requiring MRV to pay $917,000 to a member of EDSLan management to acquire 3.33% of EDSLan by December 31, 2009. The sale was completed on January 7, 2010. The results of operations of EDSLan for the seven day period ended January 7, 2010 were not included in the Company's 2010 results because they were not material. The Company has reflected the results of this business as discontinued operations in the consolidated statement of operations for all years presented. EDSLan was historically recorded in the Network Integration segment. The Company has recorded a loss of $6.9 million in 2009 to write down the assets of EDSLan to their net realizable value, including a goodwill impairment of $2.4 million.

4. Goodwill

In accordance with ASC 350 Intangibles — Goodwill and Other, goodwill and intangible assets with indefinite lives are measured for impairment at least annually, or when events indicate that impairment exists. Intangible assets that are determined to have definite lives are amortized over their useful lives.

The following table summarizes the changes in carrying value of goodwill (in thousands):


	Network Equipment			Network Integration			Total

Goodwill	$	168,765		$	23,141		$	191,906
Accumulated impariment losses and amortization	(157,337		)	(9,930		)	(167,267		)

Balance as of December 31, 2009	11,627			14,079			25,706

Impairment at Turnkey	—			(1,226		)	(1,226		)

Balance as of December 31, 2010	$	12,829		$	13,672		$	26,501

Goodwill represents the excess of the purchase price of the net assets of acquired entities over the fair value of such assets. MRV performs an annual impairment test as of October 1 each year. A two-step test is used to identify the potential impairment and to measure the amount of the impairment, if any. The first step is based upon a comparison of the fair value of each of the Company's reporting units, as defined, and the carrying value of each reporting unit's net assets, including goodwill. If the fair value of the reporting unit exceeds its carrying value, goodwill is considered not impaired; otherwise goodwill is impaired and the loss is measured by performing step two of the test. Under step two the fair value of goodwill, calculated as the difference between the fair value of the reporting unit and the fair value of the assets of the reporting unit, is compared to the carrying value of goodwill. The excess of the carrying value of goodwill over the implied fair value represents the amount of goodwill which is impaired.

MRV used an Income Approach — Discounted Cash Flow model, with some weighting given to the Market Approach to calculate the estimated fair value of the reporting units. Discounted cash flows were compiled using cash forecasts for each reporting unit, consistent with data obtained from industry analysts and internal consultations. The forecasts used a combination of past results, current and future economic factors, and the Company's strategy for the future and strategic growth by business unit.

The step one analysis in 2010 indicated that the carrying value of TurnKey, one of our reporting units in the Network Integration group, which had a 46% decline in revenue and an operating margin of negative 6% in 2010, exceeded its market value. Accordingly the Company performed a step two analysis for that reporting unit. Under the step two analysis, the Company measured the implied fair value of TurnKey's goodwill by valuing of its tangible and intangible assets and liabilities in a manner similar to the allocation of purchase price in a business combination. The discounted cash flow model uses significant unobservable inputs, considered Level 3 within the fair value hierarchy as established in ASC 820-10 Fair Value Measurements. The carrying value of a TurnKey's goodwill exceeded its implied fair value by $1.2 million, and the Company recorded an impairment charge of that amount to reduce the carrying value to the implied market value.

MRV records valuation allowances against deferred income tax assets, when necessary, in accordance with ASC 740 Accounting for Income Taxes. Realization of deferred income tax assets, such as net operating loss ("NOL") carry forwards and income tax credits, is dependent on future taxable earnings and is therefore uncertain. At least quarterly, the Company assesses the likelihood that the deferred income tax asset balance will be recovered from future taxable income. To the extent management believes that recovery is unlikely, the Company establishes a valuation allowance against the deferred income tax asset, which increases income tax expense in the period such determination is made. During 2010 the Company released the valuation allowance of $3.9 million related to operations in certain foreign jurisdictions based on an assessment that future benefits will be realized through future expected profits. Also, during 2010, the Company recorded an additional valuation allowance totaling $20.1 million against additional deferred income

tax assets, principally domestic capital loss carryforwards resulting from the sale of Source Photonics, domestic net operating losses and unrealized income tax credits due to a history of net losses. Although realization is not assured, management believes it is more likely than not that the net deferred income tax assets, which relate primarily to profitable foreign subsidiaries, will be realized.

As of December 31, 2010, MRV had federal, state, and foreign NOL carry forwards available of $176.5 million, $156.8 million and $88.7 million, respectively. For the year ended December 31, 2010, federal NOL carry forwards decreased by $52.1 million, and state net operating loss carry forwards increased by $14.0 million, principally from the sale of Source Photonics. For federal and state income tax purposes, the NOLs are available to offset future taxable income through 2030. Certain foreign NOL carry forwards and tax credits are available indefinitely. As of December 31, 2010, federal and state capital loss carry forwards amounted to $107.8 million, and $48.1 million, respectively. The capital loss carry forwards, which were generated by the sale of Source Photonics, expire in 2015.

Under the provisions of ASC 718 Compensation — Stock Compensation, MRV recognizes tax benefits associated with the exercise of stock options and vesting of restricted stock directly to stockholders' equity only when realized. Accordingly, deferred tax assets are not recognized for NOL carry forwards resulting from these tax benefits occurring from January 1, 2006 onward. A tax benefit occurs when the actual tax benefit realized upon an employee's disposition of a share-based award exceeds the deferred tax asset, if any, associated with the award. At December 31, 2010, deferred tax assets do not include $1.0 million of loss carryovers from share-based compensation.

MRV has not recorded U.S. income tax expense for foreign earnings that it has declared as indefinitely reinvested offshore, thus reducing its overall income tax expense. At December 31, 2010, MRV had approximately $72.7 million of accumulated but undistributed earnings at certain foreign entities. The amount of earnings designated as indefinitely reinvested offshore is based upon our expectations of the future cash needs of the Company's foreign entities. Income tax considerations are also a factor in determining the amount of foreign earnings to be repatriated.

In the event actual cash needs of the Company's U.S. entities exceed current expectations or the actual cash needs of the Company's foreign entities are less than expected, the Company may need to repatriate foreign earnings that have been designated as indefinitely reinvested offshore. This would result in recording additional U.S. income tax expense.

With limited exception, the Company is no longer subject to U.S. federal audits by taxing authorities for years through 2006 and certain state, local and foreign income tax audits through 2004 to 2006. The Company does not anticipate a significant change to the total amount of unrecognized tax benefits within the next 12 months. No reserve was needed or recorded under ASC 740, as the topic relates to accounting for uncertainty in income taxes as of December 31, 2010.

The Company recognized an income tax expense of $0.7 million, $2.1 million, for the years ended December 31, 2010, 2009, respectively, and a tax benefit of $44,000 for the year ended December 31,2008 related to discontinued operations.

7. Short-Term Debt

Short-term debt consists of secured and unsecured lines of credit and a short-term loan. As of December 31, 2010 and 2009, short-term debt totaled $18.0 million and $14.9 million, respectively. Customer accounts receivables of our subsidiary, Tecnonet, have been pledged as collateral on these borrowings. Short-term debt bears interest ranging from 2% to 3%, and the weighted average interest rates were approximately 2.0% and 2.1% as of December 31, 2010 and 2009, respectively. These obligations are incurred and settled in local currencies of the respective subsidiaries.

8. Derivative Financial Instruments

MRV, through certain foreign offices, periodically enters into foreign exchange and interest rate swap contracts. All derivatives are held for purposes other than trading. The fair values of the derivatives are recorded in other current or non-current assets or liabilities in the accompanying Balance Sheets. No hedging relationship is designated for these derivatives held and they are marked to market through earnings. The fair value of these derivative instruments is based on quoted market prices. Cash flows from financial instruments are recognized in the Statements of Cash

Table of Contents

Flows in a manner consistent with the underlying transactions.

Foreign Exchange Contracts. Certain foreign offices of MRV enter into foreign exchange contracts in an effort to minimize the currency exchange risk related to purchase commitments denominated in foreign currencies. These contracts cover periods commensurate with known or expected exposures, generally less than 12 months, and are principally unsecured foreign exchange contracts with carefully selected banks. The market risk exposure is essentially limited to risk related to currency rate movements. As of December 31, 2010 and 2009, there were no outstanding foreign currency contracts.

Interest Rate Swaps. From time to time, Tecnonet manages its debt portfolio by utilizing interest rate swaps to achieve an overall desired position of fixed and floating rates. As of December 31, 2010 and 2009 Tecnonet did not have any interest rate swaps outstanding.

9. 401(k) Plan

MRV sponsors a 401(k) plan to provide retirement benefits for its U.S. employees. As allowed under Section 401(k) of the Internal Revenue Code, MRV's plan provides for tax-deferred salary contributions for eligible employees. The Plan allows employees to contribute a portion of their annual compensation to the plan on a pretax basis. The Company currently matches pretax contributions up to 50% of the first 6% of eligible earnings contributed by employees, however the Company had reduced its matching rate to 25% for 2010. Matching contributions to the Plan totaled $286,000, $630,000, and $762,000 for the years ended December 31, 2010, 2009 and 2008, respectively.

10. Commitments and Contingencies

Lease Commitments

MRV leases certain facilities and equipment under non-cancelable operating lease agreements expiring in various years through 2020. Following are the aggregate minimum annual lease payments under leases in effect as of December 31, 2010 (in thousands):


Years ending December 31,
2011	$	4,725
2012	4,050
2013	2,901
2014	2,409
2015	2,264
Thereafter	7,284
Total	$	23,633

Annual rental expense under non-cancelable operating lease agreements for the years ended December 31, 2010, 2009 and 2008, was $4.5 million, $4.7 million and $6.0 million, respectively.

Royalty Commitment

Through subsidiaries in Israel, MRV is obligated to the Office of the Chief Scientist of the Government of Israel ("Chief Scientist") with respect to the government's participation in research and development expenses for certain products. The royalty to the Chief Scientist is recorded in cost of goods sold, and is calculated at a rate of 2% to 5% of sales of such products developed with the participation, up to the cost of such participation. The remaining future obligation as of December 31, 2010 is $335,000, which is contingent on generating sufficient sales of this selected product line. Amounts received from the participation of the Chief Scientist are offset against the related research and development expenses incurred. MRV did not receive participation from the Chief Scientist for the years ended December 31, 2010, 2009 or 2008.

Litigation

In connection with the acquisition of Fiberxon, Inc. in July 2007, MRV recorded a potential deferred consideration payable related to post-acquisition obligations of MRV pursuant to the purchase agreement. MRV filed an affirmative lawsuit in the California Superior Court in March 2009 against: a) former stockholders, seeking to cancel a potential deferred consideration obligation of approximately $31.5 million; and b) certain former executives, directors and

December 31, 2010

stockholders of Fiberxon alleging fraud and other claims. MRV entered into a Settlement Agreement and Release in December 2009 with Yoram Snir, personally and in his capacity as Stockholders' Agent for the former stockholders of Fiberxon. Pursuant to the settlement agreement, MRV has fully settled any obligation to pay the first $18 million of potential deferred consideration. This amount was reserved for set-off in the original merger agreement, and the former Fiberxon stockholders, pursuant to the settlement, were entitled to their pro rata portion of the $1.5 million settlement amount. Additionally, MRV agreed to pay up to $4.5 million to settle claims relating to the remaining $13.5 million of the potential deferred compensation. The second portion of the settlement was with the former stockholders directly, and stockholders holding 67% of the former shares elected to participate in this portion of the settlement. The remaining deferred payment obligation as of December 31, 2010 of $4.6 million represents the remaining shareholders' pro rata share of the $13.5 million portion.

MRV did not settle the California Superior Court action with four remaining defendants, and in December 2010, the court issued a default judgment against them in the amount of $57.4 million, jointly and severally, for the tort causes of action alleged in MRV's complaint, and ordered that MRV shall have no further obligations under the merger agreement including the deferred payment obligations. The defendants have submitted pleadings with the court to set aside the default judgment. MRV is currently evaluating the enforceability of this judgment against the defendants who likely may not reside or have assets in the United States. To date, MRV has not recognized any income related to this judgment due to the uncertainty of collection. Further, in 2010, four former stockholders who owned approximately 27% of the former Fiberxon did not participate in the second portion of the settlement and initiated litigation in Beijing, PRC against MRV, Source Photonics LLC and other related parties alleging a claim for approximately $3.7 million, representing these former stockholders' pro rata amount of the $13.5 million portion of the potential deferred compensation. In December 2010, two of the plaintiffs with claims of approximately $0.8 million, voluntarily withdrew their suits without prejudice. In connection with the sale by MRV of Source Photonics in October 2010, we agreed to indemnify the buyer against certain litigation, including these actions.

In connection with the Company's past stock option grant practices, MRV and certain of its current and former directors and officers have been subjected to a number of ongoing stockholder lawsuits. In June 2008, MRV announced that the Board of Directors, based on information provided by management, and in consultation with management, concluded that the financial statements and the related reports of our independent public accountants should not be relied upon due to MRV's intention to restate its financial results from 2002 through 2008 to correct its accounting for option grants and other issues. The Board of Directors appointed a Special Committee of independent directors, along with independent legal counsel and outside accounting experts, to investigate the issues, and a restatement of the Company's financial statements was filed in its Annual Report on Form 10-K for the year ended December 31, 2008 in October 2009.

From June to August 2008, five purported stockholder derivative and securities class action lawsuits were filed in the U.S. District Court in the Central District of California and one derivative lawsuit was filed in the Superior Court of the State of California against the Company and certain of MRV's current and former officers and directors. The five lawsuits filed in the Central District of California were consolidated. Claims were asserted under Section 10(b) and 20(a) of the Exchange Act, and Rule 10b-5 promulgated thereunder. The allegations set forth in the complaints were based on facts disclosed in the Company's press release of June 5, 2008, which stated that MRV's financial statements could not be relied on due to its historical stock option practices and related accounting. The complaints sought to recover from the defendants unspecified compensatory and punitive damages, to require MRV to undertake reforms to corporate governance and internal control procedures, to obtain an accounting of stock option grants found to be improper, to impose a constructive trust over stock options and proceeds derived therefrom, to disgorge from any of the defendants who received allegedly improper stock options the profits obtained therefrom, to rescind improperly priced options, and to recover costs of suit, including legal and other professional fees and other equitable relief. In November 2010, the judge overseeing the securities class action lawsuits gave final approval to a stipulated $10 million settlement agreement, which was covered by the Company's director and officer insurance policies.

Motions to dismiss the defendants were heard in the second half of 2010 in both the federal and California state derivative lawsuits, and certain defendants and claims were dismissed. Discovery continues in these matters. MRV and plaintiffs in the federal and state derivative lawsuits have attended mediations but have not been successful in reaching a settlement of these claims.

From time to time, MRV has received notices from third parties alleging possible infringement of patents with respect to product features or manufacturing processes. Management believes such notices are common in the communications industry because of the large number of patents that have been filed on these subjects. The Company's policy is to discuss these notices with the parties in an effort to demonstrate that MRV's products and/or processes do not violate any patents. The Company has been involved in such discussions with International Business Machines, Alcatel-Lucent, Ortel Communications, Ltd., Nortel Networks Corporation, Rockwell Automation, Inc., The Lemelson Foundation, Finisar Corporation and Apcon, Inc. in the past.

MRV has been named as a defendant in lawsuits involving matters that the Company considers routine to the nature of its business. Management is of the opinion that the ultimate resolution of such matters will not have a material adverse effect on our business, operating results and financial condition.

11. Product Warranty and Indemnification

As of December 31, 2010 and 2009, MRV's product warranty liability recorded in accrued liabilities was $1.0 million and $1.3 million, respectively. The following table summarizes the activity related to the product warranty liability (in thousands):


	Balance at beginning of period		Charged to expense		Deductions		Foreign currency impact		Balance at end of period
December 31, 2008	$	1,544	441		(526	)	—		$	1,459
December 31, 2009	$	1,459	318		(517	)	(3	)	$	1,257
December 31, 2010	$	1,257	(139	)	(107	)	13		$	1,024

MRV accrues for warranty costs as part of its cost of sales based on associated material product costs, technical support labor costs and associated overhead. The products sold are generally covered by a warranty for periods of one to two years.

In the normal course of business to facilitate sales of its products, MRV indemnifies other parties, including customers, lessors and parties to other transactions with us, with respect to certain matters. The Company has agreed to hold the other party harmless against losses arising from a breach of representation or covenants, or out of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim.

In addition, the Company has indemnification obligations to its current and former officers, directors, employees and agents, as set forth in the Company's bylaws.

MRV cannot estimate the amount of potential future payments, if any, that it might be required to make as a result of these obligations. Over the last decade, the Company has not incurred any significant expense as a result of obligations of this type that were not otherwise covered by our insurance policies. Accordingly, the Company has not accrued any amounts for such indemnification obligations. However, there can be no assurances that expenses will not be incurred under these indemnification provisions in the future.

12. Stockholders' Equity

Authorized Shares

On May 29, 2007, MRV stockholders approved an increase in the authorized number of $0.0017 par value Common Stock shares from 160 million to 320 million shares. The Company is authorized to issue up to 1 million shares of its $0.01 par value Preferred Stock.

Stock Repurchase Program

In 2002, MRV's Board of Directors approved a program to repurchase up to 7.0 million shares of MRV Common

Table of Contents

MRV Communications, Inc.

Notes to Consolidated Financial Statements (Continued)

December 31, 2010

Stock. Through December 31, 2010, the Company has repurchased a total of 1.4 million shares at a cost of $1.4 million under this program.

On September 13, 2010, the Company announced that the Board of Directors approved a repurchase of shares of Common Stock of the Company in an amount up to $10.0 million under a stock repurchase program. The program expires on December 31, 2011.The Company purchased 1.1 million shares under this program during the year ended December 31, 2010 at a total cost of $1.5 million.

Equity Grants

MRV's equity plans provide for granting options, restricted stock or other forms of equity to purchase shares of MRV's Common Stock, to employees, directors and non-employees performing consulting or advisory services for the Company. Under these plans, stock options exercise prices generally equal the fair market value of MRV's Common Stock at the date of grant and restricted stock grants do not have exercise prices. The options and restricted stock generally vest over six months to four years with expiration dates ranging from six and ten years from the date of grant depending on the plan. The Company's 2007 Omnibus Plan provides for granting options, restricted stock, and other forms of equity, and is at the discretion of the Board of Directors. As of December 31, 2010, 7.2 million options to purchase shares of Common Stock were available for future awards under the plan. See Note 13 "Share-Based Compensation" for additional discussion.

13. Share-Based Compensation

The Company recognizes compensation expense on awards that are ultimately expected to vest, under ASC 718 Compensation — Stock Compensation, using a straight-line amortization method based on the grant date estimated fair value method under ASC 718, reduced for estimated forfeitures. The following table summarizes the impact on our results of operations of recording share-based compensation (in thousands):


Years ended December 31,	2010		2009		2008
Cost of sales	$	49	$	67	$	139
Product development and engineering	125		342		482
Selling, general and administrative	1,572		1,089		1,805
Total share-based compensation expense	$	1,746	$	1,498	$	2,426

The amount of share-based compensation expense capitalized as part of inventory was insignificant for all periods presented. The weighted average fair values of awards granted during the years ended December 31, 2010, 2009 and 2008 were $0.93, $0.57 and $0.88 per share, respectively. The total fair value of shares vesting during the years ended December 31, 2010, 2009 and 2008 was $1.7 million, $2.5 million and $4.0 million, respectively. For the years ended December 31, 2010, 2009, and 2008, the income tax benefits realized from exercised stock options and similar awards was immaterial. As of December 31, 2010, the total unrecorded deferred share-based compensation balance for unvested shares, net of expected forfeitures, was $3.0 million which is expected to be amortized over a weighted-average period of 2.07 years.

Valuation Assumptions

MRV uses the Black-Scholes option pricing model to estimate the fair value of share-based awards. The Black-Scholes model requires the use of subjective assumptions, including the option's expected life and the underlying stock price volatility. The Company assumes that future volatility approximates historical volatility.

The following weighted average assumptions were used for estimating the fair value of options granted during each of the following years:

Risk-free interest rate	1.6	%	2.2	%	3.2	%
Dividend yield	—	%	—	%	—	%

The aggregate intrinsic value represents the total pre-tax intrinsic value, based on MRV's closing stock price of $1.79 at December 31, 2010, which would have been received by award holders had all award holders exercised in-the-money awards as of that date.

14. Segment Reporting and Geographical Information

MRV divides and operates its business based on two segments: the Network Equipment group and the Network Integration group. The Network Equipment group designs, manufactures and distributes optical networking solutions and Internet infrastructure products, and the Network Integration group provides value-added integration and support services for customers' networks. On October 26, 2010, MRV sold Source Photonics. Source Photonics, together with Appointech, another small business unit, comprised the Optical Components group. Following the disposition of Source Photonics, Appointech was aggregated with the Network Equipment group. The historical financial information in these consolidated financial statements has been reclassified to reflect Source Photonics as a discontinued operation and to reflect Appointech in the Network Equipment segment for all periods presented.

The accounting policies of the segments are the same as those described in the summary of significant accounting polices in Note 2. MRV evaluates segment performance based on revenues, gross profit and operating income of each segment. As such, there are no separately identified segment statements of operations data below operating income.

The following summarizes business segment revenues, including intersegment revenues (in thousands):


Years ended December 31:	2010			2009			2008
Network Equipment group	$	125,950		$	105,977		$	126,978

of-band network equipment, defense and aerospace network applications, the related service revenue and fiber optic components sold as part of system solutions. Network Integration revenue primarily consists of value-added integration and support service revenue, related third-party product sales (including third-party product sales through distribution) and fiber optic components sold as part of system solutions.

One customer generated $44.8 million, $36.5 million, and $27.1 million of revenues in the Network Integration group, or 17%, 15%, and 10% of total revenues for the years ended December 31, 2010, 2009, and 2008, respectively.

As of December 31, 2010, amounts due from one customer in the Network Integration group accounted for 22% of accounts receivables. The same customer accounted for 19% of accounts receivables as of December 31, 2009.

18. Noncontrolling Interests

In June 2009, the Company completed the purchase of 833,333 shares of Series A Preferred Stock and 12.8 million shares of common stock of its majority-owned subsidiary Charlotte's Networks, Inc. The total purchase price was $1.5 million. After the purchase, MRV owned all of the preferred stock and 99.7% of the common stock of Charlotte's Networks. On August 4, 2009 the subsidiary was merged into MRV. The $1.0 million difference between the purchase price and the carrying amount of the noncontrolling interest was recognized as a reduction of MRV equity.

On October 29, 2010 the Company completed the purchase of the remaining 40 percent interest in Tecnonet S.p.A, its majority owned Italian Network Integration subsidiary, for $5.6 million. After the purchase, MRV is the 100% owner of Tecnonet S.p.A. The noncontrolling interest's share of the net book value of Tecnonet was $6.7 million as of the date of the transaction. The amount by which the noncontrolling interest balance exceeded the purchase price was recorded as an increase in MRV equity.

Item 9A. Controls and Procedures.

Disclosure Controls and Procedures

We evaluated the design and operation of the effectiveness of our disclosure controls and procedures as of December 31, 2010, under the supervision and with the participation of our management, pursuant to Rule 13a-15(b) of the Exchange Act. Based on the remedial steps taken in mitigating risks relating to the 2009 identified material weakness, and the ability to sustain improvements relating to disclosure and financial reporting, management concluded that our disclosure controls and procedures as defined in Rule 13a-15(e) as of December 31, 2010 were effective.

To further address any remaining risks identified in our internal control over financial reporting, the Company performed additional manual procedures and analysis and other post-closing procedures in order to prepare the audited consolidated financial statements included in this Form 10-K. Notwithstanding the remaining remedial efforts to improve deficiencies in our internal control over financial reporting as of December 31, 2010, we believe that the audited consolidated financial statements contained in this Form 10-K present our financial condition, results of operations, and cash flows as of the dates, and for the periods, presented, in conformity with GAAP.

Management's Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, pursuant to Rule 13a-15(c) of the Exchange Act. This system is intended to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP.

A company's internal control over financial reporting includes policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

In accordance with the internal control reporting requirements of the SEC, our management completed an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2010. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). The COSO framework summarizes each of the components of a company's internal control system, including the: (i) control environment; (ii) risk assessment; (iii) information and communication; and (iv) monitoring, as well as a company's control activities. Based on this assessment, our management has determined that our internal control over financial reporting as of December 31, 2010 was effective.

Table of Contents

Management's continual efforts to improve the design and operating effectiveness of our internal controls over financial reporting have led to the conclusion that deficiencies and significant deficiencies identified that aggregated and resulted in a material weakness in the control environment in 2009 have been remediated and remaining deficiencies do not rise to the level of a material weakness. Management has not identified any material weaknesses resulting from design and/or operating effectiveness in the internal control system. A "material weakness" is defined as a significant deficiency, or combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected.

The effectiveness of our internal control over financial reporting as of December 31, 2010, has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Changes in Internal Control over Financial Reporting and Remediation of the Material Weaknesses

Based on the additional procedures performed as part of the Company's ongoing remediation of its financial controls, management has concluded that effective improvements were made to the internal control system to mitigate the material weaknesses identified in 2009. Since December 31, 2009, we have implemented the following remediation measures to address the material weaknesses that existed as of that date:


•	We have implemented a Transaction Authority Matrix clearly documenting the delegation of authority and approval requirements for non-standard transactions and journal entries.


•	We have improved and streamlined the financial statement close process through the implementation of consolidation software.


•	We have developed a detailed annual operating plan that is used to identify and investigate variances where necessary.


•	We have increased the frequency of business unit reporting from quarterly to monthly.


•	We are conducting more frequent and more in-depth periodic audits of controls at the subsidiary level.

Inherent Limitation on the Effectiveness of Internal Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all errors and all misconduct. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of misconduct, if any, within the Company have been detected. These inherent limitations include, but are not limited to, the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of a single person, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or misconduct may occur and not be detected.

MRV Communications, Inc.'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 included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on 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 based on the assessed risk, 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 generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

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

In our opinion, MRV Communications, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010 based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of MRV Communications, Inc. as of December 31, 2010 and 2009, and the related consolidated statements of operations, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2010, and our report dated March 16, 2011, expressed an unqualified opinion thereon.
