Quantum Corporation (“Quantum”, the “Company”, “us” or “we”), founded in 1980, is a global expert in data protection and big data management. We provide solutions for storing and protecting information in physical, virtual, cloud and big data environments that are designed to help customers be certain they are maximizing the value of their data over its entire lifecycle. With our solutions, customers can better adapt in a world of continuing change by keeping and protecting more data for a longer period of time while reducing costs and increasing return on investment. We work closely with a broad network of distributors, value-added resellers (“VARs”), direct marketing resellers (“DMRs”), original equipment manufacturers (“OEMs”) and other suppliers to meet customers’ evolving data protection and big data management needs. Our stock is traded on the New York Stock Exchange under the symbol QTM.

Our data protection solutions include DXi^® deduplication systems and Scalar^® automated tape libraries that optimize backup and recovery, simplify management and lower cost and our vmPRO^TM virtual server backup and disaster recovery offerings that protect virtual environments while minimizing the impact to servers and storage. In addition, we also offer software for cloud backup and disaster recovery of physical and virtual servers. For big data environments, we provide StorNext^® tiered storage and Lattus^TM object storage solutions designed to help maximize revenue and results by enabling customers to extract the full value from their digital assets. We have a full range of services and the global scale and scope to support our worldwide customer base.

We are a member of the consortium that develops and has licensed LTO^® media technology to tape media manufacturing companies. We receive royalty payments for both LTO and DLT^® media technology sold under licensing agreements. We have also entered into various licensing agreements with respect to our technology, patents and similar intellectual property which provide licensing revenues in certain cases and may expand the market for products and solutions using these technologies.

As a specialist providing end user customers with differentiated data protection and big data management solutions, our strategy is to continue to grow the independent channel for Quantum branded solutions and to increase revenue by offering products with superior performance and value. We plan to continue to expand and improve our product and solution offerings, with emphasis on branded disk systems, software solutions, virtual offerings, cloud solutions and next generation object storage. Using a balanced approach to take advantage of market opportunities and investing for growth while in a period of economic uncertainty, we are focused on revenue growth balanced with operating profit and generating cash from operations.

Information Technology (“IT”) departments face an environment of change. There is increasing focus on the economics of data as these departments not only address continued data growth but also identify solutions to store more data for longer periods of time as data becomes more valuable. With new ways to analyze and reuse data for additional revenue streams, new ideas and operational breakthroughs, IT managers are looking to ensure the organization can take full advantage of the information and knowledge from that data. For these reasons, data protection and big data management are important to businesses and organizations and consistently are reflected as top priorities in end user research studies.

Another change that has occurred over the last several years is the emergence of new architectures and technologies that reduce costs and increase efficiency. These include data deduplication, scale-out storage, virtualization and cloud storage. The challenge is that these technologies can also introduce disruption for IT, so it takes careful planning and smart solutions to enable organizations to move forward.

In the face of these changes, IT departments also confront continued constraints. Resources and budgets remain tight, which is one of the main reasons reducing data acquisition costs and ongoing operational costs is a top priority. In addition, even as they look to capitalize on new technologies and solutions, many IT managers still have to support legacy environments and applications. Finally, there is often built-in inertia or risk aversion when it comes to changing architectures or existing vendors. As a result, there is significant opportunity for storage specialists such as Quantum to assist organizations through transition.

With new digital technologies creating larger data files that can generate greater business value, there is a growing need to retain data for progressively longer periods while maintaining visibility and access to it. IT departments are increasingly focused on managing this big data. Generally, big data refers to relatively new data types that produce large files, often measured in petabytes, such as video, imaging and audio. Big data also refers to large collections of small data, such as retail purchasing information, underwater photos of the ocean floor and feeds from traffic cameras that when combined, create meaning and increasingly, competitive advantage. In addition, in managing big data, organizations are increasingly recognizing that they need efficient and cost-effective ways to archive it. We offer StorNext software and appliance-based solutions, in addition to Lattus object storage, to address this growing need for managing and archiving big data.

Designed for data-intensive environments, our StorNext software reduces the time and total cost of managing data for end users with large data sets and challenging distributed environments. The StorNext File System software provides high-performance shared access to data across different networks, operating systems and storage platforms. In addition, our StorNext Storage Manager^TM software automatically copies and migrates data between different tiers of storage based on user-defined policies. The result is a highly scalable, high-performance data management solution designed to optimize the use of storage while enabling the long-term protection and recoverability of data.

Our StorNext software helps businesses with big data to benefit from workflow efficiencies, automated tiered storage and policy-based archive management. Designed for open system data-intensive environments, StorNext software products allow multiple users to rapidly access a single data set, increasing productivity and storage utilization. They also transparently move data, reducing storage costs while simultaneously providing embedded data protection. For several years, organizations within rich media production and broadcasting, the federal government, life sciences and other disciplines have utilized our data management software to derive more value from their data while controlling costs. Many of these customers now rely on our software as a key technology enabler for their business processes and workflow.

Our StorNext appliances leverage the power of StorNext software and market-leading hardware to offer predictable high-performance file sharing and archiving in purpose-built configurations of metadata controllers, expansion appliances and disk and archive enabled libraries. They are simple to deploy and architected to deliver scalable, industry-leading performance, drive lower operational costs and provide a flexible open system for enabling third party applications. These appliances also work seamlessly with traditional StorNext software and partner hardware offerings to provide additional options for building a shared storage area network (“SAN”) and scale out network-attached storage (“NAS”) environment. They are intended to serve a wide range of markets, such as film editing, seismic processing or genome sequencing and balance the highest performance with the lowest long-term cost for sharing big data files in data intensive operations.

Our family of Lattus object storage solutions enables high volumes of data to be immediately available to extract valuable information at any time, and over time. The Lattus family is designed as a forever disk archive with wide-ranging scalability from 500 terabytes to hundreds of petabytes with predictable retrieval times for high speed file access. They decrease capital and operating costs by using drives that have lower power and cooling requirements. In addition, they have self-healing capabilities that offer extremely high durability to ensure data is not lost and virtually eliminates unscheduled maintenance and performance degradation. Lattus has been designed to be self-migrating through innovative algorithms that simplify upgrades to new storage technologies.

Our DXi disk-based backup systems meet the needs of a broad range of customers, from small businesses and remote offices to large distributed enterprise data center environments, seeking high speed recovery and extreme reliability beyond what a tape-only environment can deliver. These solutions offer functionality normally reserved for enterprise class data centers, such as data deduplication, virtual tape, snapshot, data recovery and replication capabilities. Our disk-based backup appliances are designed for easy implementation and integration into existing environments and provide industry-leading performance, capacity and price-performance.

Our DXi disk systems use deduplication technology to expand the amount of backup data users can retain on traditional disk systems. The result is a cost-effective means for IT departments to store backup data on disk for months instead of days, providing high-speed restores, increasing available data recovery points and reducing media management. For disaster recovery in distributed environments, the DXi-Series^TM also makes wide area network (“WAN”) replication practical because of the greatly reduced bandwidth required with data deduplication. By greatly increasing effective disk capacity, data deduplication enables users to retain backup data on fast recovery disk much longer than possible using conventional disk and significantly reduces the bandwidth needed to move data between sites. We hold a key patent in one of the most efficient methods of data deduplication, known as variable-length data deduplication.

Our DXi-Series systems provide a combination of high performance and advanced functionality. In addition to data deduplication, the core set of advanced features of the DXi-Series includes a high performance embedded file system, support for high speed data compression, asynchronous replication, direct tape creation and built-in monitoring and diagnostic tools.

Our virtual environment offerings include vmPRO software and vmPRO appliances. Our vmPRO software provides virtualization data protection software with advanced utilities designed to dramatically improve and simplify virtual data protection in midrange and larger data centers. It works with our DXi family of deduplication products to accelerate backup, restore and disaster recovery protection in data center virtual environments while reducing IT costs. We also offer vmPRO appliances that provide an integrated data protection solution designed to simplify backups in virtual environments. These appliances include both backup software and integrated storage with deduplication in a single solution for small to medium-size businesses and remote offices. The vmPRO appliances optimize virtual machines and accelerate performance by filtering out unassigned, expired and inactive data to reduce overhead on servers, networks and storage.

We are a leading supplier of tape automation products and we continue to expand features and capabilities of our tape library offerings to increase storage capacity and improve performance. Our Scalar tape automation portfolio includes a range of products, from autoloaders with one tape drive and up to sixteen cartridges to large enterprise-class libraries which can hold hundreds of drives and thousands of cartridges. Our tape libraries intelligently manage and protect business critical data in workgroup, medium size business and enterprise data center environments. With an emphasis on ease of use, management features and investment optimization, Scalar tape libraries are designed to grow with business needs. These products integrate tape drives into a system with automation technology, advanced connectivity and sophisticated management tools, including integrated media integrity analysis in tape drives and library diagnostic systems. We also offer the SuperLoader^®3 autoloader designed to maximize data density and performance.

Tying our libraries together from entry-level to enterprise is a common, integrated software called iLayer™, which provides monitoring, alerts and proactive diagnostics, thereby reducing service calls, shortening issue resolution time and decreasing the time users spend managing their tape automation solutions. In addition, we believe the growth in archiving of unstructured data represents a substantial opportunity for tape automation systems. To capitalize on this trend and the changing role of tape automation systems in data protection, we have invested in our enterprise Scalar i6000 and midrange Scalar i500 platforms to provide increased redundancy capabilities. These platforms can be implemented on their own or in an appliance configuration with our StorNext archiving software.

Our device and media products include removable disk drives and libraries, NAS appliances and tape drives and media. Our RDX^® removable and ruggedized disk backup devices combine attributes of disk and tape, with deduplication technology offered in our RDX disk libraries. Our NAS appliance has built-in backup software and deduplication technology, designed to enable businesses to significantly reduce storage requirements and network traffic.

We offer tape drives and media based on the LTO format and added LTO-6 technology to our portfolio in fiscal 2013. Our LTO family of devices is designed to deliver outstanding performance, capacity and reliability, combining the advantages of linear multi-channel, bi-directional formats with enhancements in servo technology, data compression, track layout and error correction. These LTO tape drives are designed to provide midrange and enterprise customers with disaster recovery and cost-effective backup solutions.

We also sell a full range of storage media offerings to complement each tape drive technology and satisfy a variety of specific media requirements. Our media is compatible with our drives, autoloaders and libraries as well as other industry products.

We offer a software platform to help customers take advantage of cloud-based data protection through a highly optimized, flexible approach designed to overcome the limitations of other cloud offerings. This platform is centered on our vmPRO technology and our virtual deduplication appliance, the DXi V1000^TM. Our cloud-based data protection platform leverages our expertise in data protection to deliver a highly efficient, cost-effective foundation for cloud-based backup, restore and data recovery that helps customers transition easily and practically to the cloud on their terms and timeframe. Our approach is based on knowledge that most customers continue to use both disk and tape for data protection on a mix of physical and virtual servers and are more comfortable with a hybrid cloud strategy. This focus on flexibility is reflected in the benefits provided by our cloud-optimized software platform including fast restores, cost-effective disaster recovery and business continuity, significant data reduction and WAN-optimized replication.

Our global services strategy is an integral component of our total customer solution. Service is typically a significant purchase factor for customers considering either big data management or data protection and storage solutions, and our ability to provide comprehensive service and support can present us with a noteworthy competitive advantage to attract new customers and retain existing customers. In addition, we believe that our ability to retain long-term customer relationships and secure repeat business is frequently tied directly to our service capabilities and performance.

Our extensive use of technology and innovative, built-in product intelligence allows us to scale our global services operations to meet the needs of our expanding installed base. We are currently able to provide service to customers in more than 100 countries, supported by 24-hour, multi-language technical support centers located in North America, Europe and Asia. We provide our customers with warranty coverage on all of our products. Customers with high availability requirements may also purchase additional service to extend the warranty period, obtain faster response times, or both, on our disk systems, tape automation and software products. We offer this additional support coverage at a variety of response levels up to 24-hours a day, seven-days-a-week, 365-days-a-year, for customers with stringent high-availability needs. We provide support ranging from repair and replacement to 24-hour rapid exchange to on-site service support for our midrange and enterprise-class products.

We generally warrant our hardware products against defects for periods ranging from one to three years from the date of sale. We provide warranty and non-warranty services from our Colorado Springs, Colorado facility and, for certain products, through third party service providers. In addition, we utilize various other third party service providers throughout the world to perform repair and warranty services for us to reach additional geographic areas and industries in order to provide quality services in a cost-effective manner.

We compete in an industry characterized by rapid technological change and evolving customer requirements. Our success depends, in part, on our ability to introduce new products and features to meet end user needs. Our research and development teams are working on the next generation disk, data deduplication, virtual systems, cloud solutions, object storage solutions, tape automation and big data technologies as well as software solutions to advance these technologies for the big data management and archive and the data protection markets to meet changing customer requirements. We continue to focus our efforts on software solutions and integrated software and hardware solutions that offer improvements in the efficiency and cost of storing, moving, managing and protecting large amounts of data and providing solutions for the continuing convergence between backup and archive to provide compelling solutions for our customers.

We continue to invest in research and development to improve and expand our product lines and introduce new product lines, striving to provide superior data protection, including cloud environments, and big data and archive solutions. Research and development costs were $74.0 million, $74.3 million and $73.0 million for fiscal 2013, 2012 and 2011, respectively.

For Quantum-branded products, we utilize distributors, VARs and direct marketing resellers. Our integrated Quantum Alliance™ Reseller Program provides our channel partners the option of purchasing products directly or through distribution and provides them access to a more comprehensive product line. Additionally, we sell directly to a select number of large corporate entities and government agencies.

We sell our products to several OEM customers that resell our hardware products under their own brand names and typically assume responsibility for product sales, end user service and support. We also license software to certain OEM customers that include this software in their own brand name products. These OEM relationships enable us to reach end users not served by our branded distribution channels or our direct sales force. They also allow us to sell to select geographic or vertical markets where specific OEMs have exceptional strength.

Our sales are concentrated with several key customers because under our business model, as is typical for our industry, we sell to OEMs, distributors, VARs and DMRs to reach end user customers. Sales to our top five customers represented 32% of revenue in fiscal 2013, 34% of revenue in fiscal 2012 and 33% of revenue in fiscal 2011. No customer accounted for 10% or more of our revenue in fiscal 2013 and 2012. In fiscal 2011, sales to Dell comprised 10% of revenue. Through our Quantum Alliance Reseller Program and our emphasis on growing our branded business, including increasing the independent channel, we are expanding our customer base and continue to distribute our products and services across a larger number of customers.

The markets in which we participate are highly competitive, characterized by rapid technological change and changing customer requirements. In some cases, our competitors in one market area are customers or suppliers in another. Our competitors often have greater financial, technical, manufacturing, marketing or other resources than we do. Additionally, the competitive landscape continues to change due to merger and acquisition activity as well as new entrants into the market.

Our StorNext software and appliance products primarily face competition from EMC Corporation (“EMC”), International Business Machines Corporation (“IBM”) and Spectra Logic Corporation. Our virtual solutions, vmPRO software and appliances, primarily compete with virtualization startups and traditional backup application vendors. Our cloud solutions face competition from a large number of businesses that provide hardware, software and virtual solutions as well as companies that offer cloud services based on other technology. The Lattus object storage solutions primarily compete with object storage solutions from other providers, ranging from startup companies to established companies such as EMC.

Our disk solutions primarily compete with products sold by EMC, Hewlett-Packard Company (“HP”), IBM and NetApp, Inc. (“NetApp”). Additionally, a number of software companies that have traditionally been partners with us have deduplication features in their products and will, at times, compete with us. A number of our competitors also license technology from other competing companies.

In the tape automation market, we primarily compete for midrange and enterprise reseller and end user business with Dell, IBM and Oracle as well as HP through its OEM relationship with other tape automation suppliers. Competitors for entry-level and OEM tape automation business include BDT Products, Inc. and several others that supply or manufacture similar products. In addition, disk backup products are a competitive alternative to tape products and solutions.

At the storage device level, our main competitors are HP and IBM. Both HP and IBM develop and sell their own LTO tape drives, which compete with our device offerings. We also face competition from disk alternatives, including removable disk drives in the entry-level market. Although we have our own removable disk drive offerings, several other companies sell removable disk drives, such as Dell, HP and Imation Corporation.

For a discussion of risks associated with competing technologies, see the Risk Factor in Item 1A titled, “We derive the majority of our revenue from products incorporating tape technology. Our future operating results depend in part on continued market acceptance and use of products employing tape technology and decreases in the market could materially and adversely impact our business, financial condition and operating results. In addition, if we are unable to compete with new or alternative storage technologies, our business, financial condition and operating results could be materially and adversely affected.”

We utilize contract manufacturers to produce a number of our products and we manufacture various other products in our own facilities. We manufacture our disk products, vmPRO appliances, StorNext appliances and certain tape automation systems and perform device and system configuration for our North American customers from our Colorado Springs, Colorado facility. In addition, we perform test and repair for these products in that same facility.

We outsource the manufacture of certain tape automation systems, tape devices and service parts to contract manufacturers. Tape drives used in our products are primarily sourced from Hungary and Malaysia. Disk drives used in our products are largely sourced from Thailand and China. Certain tape automation system materials and assemblies as well as certain disk system materials and assemblies are sourced in China, Malaysia, Singapore, Thailand and the U.S.

Our recording tape media is manufactured by one or more tape media manufacturing companies, which are qualified and licensed to manufacture, use and sell media products. In most cases, the media is produced in Japan and multi-sourced on a worldwide basis.

We develop and protect our technology and know-how, principally in the field of data storage. As of March 31, 2013, we hold over 400 U.S. patents and have over 100 pending U.S. patent applications. In general, these patents have a 20-year term from the first effective filing date for each patent. We also hold a number of foreign patents and patent applications for certain of our products and technologies. Although we believe that our patents and applications have significant value, rapidly changing technology in our industry means that our future success will also depend heavily on the technical competence and creative skills of our employees.

From time to time, third parties have asserted that the manufacture and sale of our products have infringed on their patents. We conduct ongoing investigations into the assertions and presently believe that either licenses are not required or that any licenses ultimately determined to be required could be obtained on commercially reasonable terms. However, we cannot provide assurance that such licenses are presently obtainable, or if later determined to be required, could be obtained on commercially reasonable terms. See Item 3 “Legal Proceedings” for additional disclosures regarding on-going lawsuits alleging patent infringement.

On occasion, we have entered into various patent licensing and cross-licensing agreements with other companies. We may enter into patent cross-licensing agreements with other third parties in the future as part of our normal business activities. These agreements, when and if entered into, would enable these third parties to use certain patents that we own and enable us to use certain patents owned by these third parties. We have also sold certain patents, retaining a royalty-free license for these patents.

As is typical in our industry, we have the greatest demand for our products and services in the fourth quarter of each calendar year, or our fiscal third quarter. We usually experience the lowest demand for our products and services in the first and second quarters of each calendar year, or our fiscal fourth quarter and fiscal first quarter, respectively.

We manufacture our products based on forecasts of customer demand. We also place inventory in strategic locations in order to enable certain key customers to obtain products on demand. Orders are generally placed by customers on an as-needed basis. Product orders are confirmed and, in most cases, shipped to customers within one week. More complex systems and product configurations often have longer lead times and may include on-site integration or customer acceptance. We ship most of the backlog that we accumulate during any particular fiscal quarter in the same quarter in which the backlog initially occurs. Therefore, our backlog generally grows during each fiscal quarter and shrinks during the latter part of the quarter to reach its lowest levels at the end of that same quarter, by which time significant shipments have occurred. As a result, our backlog as of the end of any fiscal quarter is not material and is not a predictor of future sales.

YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW, TOGETHER WITH ALL OF THE OTHER INFORMATION INCLUDED IN THIS ANNUAL REPORT ON FORM 10-K. THE RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE ONLY ONES FACING QUANTUM. ADDITIONAL RISKS AND UNCERTAINTIES NOT PRESENTLY KNOWN TO US OR THAT ARE CURRENTLY DEEMED IMMATERIAL MAY ALSO IMPAIR OUR BUSINESS AND OPERATIONS. THIS ANNUAL REPORT ON FORM 10-K CONTAINS “FORWARD-LOOKING” STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES. PLEASE SEE PAGE 1 OF THIS REPORT FOR ADDITIONAL DISCUSSION OF THESE FORWARD-LOOKING STATEMENTS.

We rely on indirect sales channels to market and sell our branded products. Therefore, the loss of or deterioration in our relationship with one or more of our resellers or distributors, or our inability to establish new indirect sales channels to drive growth of our branded revenue, especially for disk systems and software solutions, could negatively affect our operating results.

We sell the majority of our branded products to value-added resellers, or VARs, and to direct marketing resellers such as CDW Corporation, who in turn sell our products to end users, and to distributors such as Ingram Micro, Inc. and others. The success of these sales channels is hard to predict, particularly over time, and we have no purchase commitments or long-term orders from them that assure us of any baseline sales through these channels. Several of our resellers carry competing product lines that they may promote over our products. A reseller might not continue to purchase our products or market them effectively, and each reseller determines the type and amount of our products that it will purchase from us and the pricing of the products that it sells to end user customers. Establishing new indirect sales channels is an important part of our strategy to drive growth of our branded revenue.

As we introduce new products and solutions, we could negatively impact our relationship with channel partners that historically have sold other products and solutions that now compete with our new offerings. For example, we introduced various StorNext appliance solutions beginning in fiscal 2012 causing us to more directly compete for hardware sales with channel partners that sold other hardware products in conjunction with our StorNext software.

Certain of our contracts with customers contain “most favored nation” pricing provisions mandating that we offer our products to these customers at the lowest price offered to other similarly situated customers. In addition, sales of our enterprise products, and the revenue associated with the on-site service of those products, are somewhat concentrated in specific customers, including government agencies and government-related companies. Our operating results could be adversely affected by any number of factors including:

We derive the majority of our revenue from products incorporating tape technology. Our future operating results depend in part on continued market acceptance and use of products employing tape technology and decreases in the market could materially and adversely impact our business, financial condition and operating results. In addition, if we are unable to compete with new or alternative storage technologies, our business, financial condition and operating results could be materially and adversely affected.

We derive the majority of our revenue from products that incorporate some form of tape technology and we expect to continue to derive significant revenue from these products in the next several years. As a result, our future operating results depend in part on continued market acceptance and use of products employing tape technology. The use of products employing tape technology continues to decrease and is projected to continue to decrease. Decreased market acceptance or use of products employing tape technology has materially and adversely impacted our business, financial condition and operating results and could materially and adversely impact our business, financial condition and operating results in the future.

Disk products as well as various software solutions and alternative technologies continue to gain broader market acceptance. We face risks that our tape customers migrate toward these products and solutions. We are addressing this risk through our own targeted investment in disk systems and other alternative technologies; however, these markets are characterized by rapid innovation, evolving customer demands and strong competition, including competition with several companies who are also significant customers. If we are not successful in our efforts, our business, financial condition and operating results could be materially and adversely affected.

If our products fail to meet our or our customers’ specifications for quality and reliability, our results of operations may be adversely impacted and our competitive position may suffer.

Although we place great emphasis on product quality, we may from time to time experience problems with the performance of our products, which could result in one or more of the following:

These factors could cause our business, financial condition and results of operations to be materially and adversely affected.

A large percentage of our sales come from a few customers, some of which are also competitors, and these customers generally have no minimum or long-term purchase commitments. The loss of, or a significant reduction in demand from, one or more key customers could materially and adversely affect our business, financial condition and operating results.

Our sales have been and continue to be concentrated among a few customers because under our business model, we sell to OEMs, distributors, VARs and DMRs to reach end user customers. Furthermore, customers are not obligated to purchase any minimum product volume and our relationships with customers are terminable at will. Revenue from OEM customers has decreased in recent years. If we experience further declines in revenue from OEM customers or any of our other large customers, we could be materially and adversely affected. In addition, certain of our large customers are also our competitors, and such customers could decide to reduce or terminate their purchases of our products for competitive reasons.

Some of our tape and disk products are incorporated into larger storage systems or solutions that are marketed and sold to end users by large OEM customers as well as VARs, channel partners and other distributors. Because of this, we have limited market access to these end users, limiting our ability to reach and influence their purchasing decisions. These market conditions further our reliance on these OEM and other large customers such as distributors and VARs. Thus if they were to significantly reduce, cancel or delay their orders with us, our results of operations could be materially and adversely affected.

A portion of our sales are to various agencies and departments of the U.S. federal government. The U.S. Congress passed the American Taxpayer Relief Act of 2012 which implemented automatic spending cuts beginning March 1, 2013. These spending cuts could decrease revenue from sales to the federal government that could materially and adversely affect our results of operations.

Our operating results depend on a limited number of products and on new product introductions, which may not be successful, in which case our business, financial condition and operating results may be materially and adversely affected.

A limited number of products comprise a significant majority of our sales, and due to rapid technological change in the industry, our future operating results depend on our ability to develop and successfully introduce new products. To compete effectively, we must continually improve existing products and introduce new ones. We have devoted and expect to continue to devote considerable management and financial resources to these efforts. We cannot provide assurance that:

If we are not successful in timely completion of our new product qualifications and then ramping sales to our key customers, our revenue and results of operations could be adversely impacted. In addition, if the quality of our products is not acceptable to our customers, this could result in customer dissatisfaction, lost revenue and increased warranty and repair costs.

We continue to face risks related to economic uncertainty and slow economic growth.

Uncertainty about economic conditions poses a risk as businesses may further reduce or postpone spending in response to reduced budgets, tightening of credit markets, negative financial news and declines in income or asset values which could adversely affect our business, financial condition and results of operations. The slow economic growth in recent years along with periods of economic uncertainty in various countries around the world have had a material and adverse impact on our business and our financial condition, including reduced demand for IT products and services overall and more specifically for products with tape technology in the data protection market. We continue to face risks related to economic conditions in Europe, including concerns about the potential default of various national bonds and debt backed by individual countries, as well the politics impacting these, which could negatively impact the U.S. and global economies and adversely affect our financial results. In addition, our ability to access capital markets may be restricted which could have an impact on our ability to react to changing economic and business conditions and could also adversely affect our results of operations and financial condition.

Competition may intensify in the data protection market as a result of competitors introducing products based on new technology standards and merger and acquisition activity, which could materially and adversely affect our business, financial condition and results of operations.

Our competitors in the data protection market for disk systems and virtual machine solutions are aggressively trying to advance and develop new technologies and products to compete against our technologies and products, and we face the risk that customers could choose competitor products over ours. Competition in our markets is characterized by technological innovation and advancement. As a result of competition and new technology standards, our sales or gross margins could decline, which could materially and adversely affect our business, financial condition and results of operations.

Technological developments and competition over the years in the tape automation market has resulted in decreased prices for tape automation products and product offerings. Pricing pressure is more pronounced in the tape automation market for entry-level products and least pronounced for enterprise products. Similar to our competitors, our products may be priced lower and often incorporate new and/or different features and technologies than prior years. We face risks that customers could choose competitor products over ours due to these features and technologies or due to pricing differences. We have managed pricing pressure by reducing production costs and/or adding features to increase value to maintain a certain level of gross margin for our tape automation systems. If competition further intensifies, or if there is additional industry consolidation, our sales and gross margins for tape automation systems could decline, which could materially and adversely affect our business, financial condition and results of operations.

Industry consolidation and competing technologies with device products, which include tape drives and removable hard drives, have resulted in decreased prices and increasingly commoditized device products. Our response has been to manage our device business at the material margin level and we have chosen not to compete for sales in intense price-based situations or if we would be unable to maintain a certain gross margin level. Our focus has shifted to higher margin opportunities in other product lines. Although revenue from devices has decreased in recent years, our material margins have remained relatively stable over this period. We have exited certain portions of the device market and have anticipated decreased sales of devices. We face risk of reduced shipments of our devices beyond our plans, and could have reduced margins on these products, which could adversely impact our business, financial condition and results of operations.

Additionally, the competitive landscape could change due to merger and acquisition activity in the data protection market. Such transactions may impact us in a number of ways. For instance, they could result in:

These transactions also create uncertainty and disruption in the market because whether a pending transaction will be completed, the timing of such a transaction and its degree of impact are often unknown. Given these factors and others, such merger and acquisition activity may materially and adversely impact our business, financial condition and results of operations.

Competition may intensify in the big data and archive market as a result of competitors introducing products based on new technology standards and merger and acquisition activity, which could materially and adversely affect our business, financial condition and results of operations.

Competition in the big data and archive market is characterized by technological innovation and advancement, including performance and scale features, and our competitors are aggressively trying to advance and develop new technologies and solutions. We face the risk that customers could choose competitor solutions over ours due to these features and technologies. As a result of competition and new technology standards, our sales from software solutions and appliances could decline, which could materially and adversely affect our business, financial condition and results of operations.

Additionally, the competitive landscape could change due to merger and acquisition activity. Transactions such as these may impact us in a number of ways. For instance, they could result in:

These transactions also create uncertainty and disruption in the market, because whether a pending transaction will be completed, the timing of such a transaction and its degree of impact are often unknown. Given these factors and others, such merger and acquisition activity may materially and adversely impact our business, financial condition and results of operations.

A significant decline in royalty, branded software or OEM deduplication software revenues could materially and adversely affect our business, financial condition and operating results.

Our royalties, branded software and OEM deduplication software revenues are relatively profitable and can significantly impact total company profitability. We receive royalty revenue based on tape media cartridges sold by various tape media manufacturers and resellers. Under our license agreements with these companies, each of the licensees determines the pricing and number of units of tape media cartridges that it sells. Our royalty revenue varies depending on the level of sales of the various media cartridge offerings sold by the licensees and other factors, including:

Our media royalties depend on royalty rates and the quantity of media consumed in the market. We do not control licensee sales of these tape media cartridges. Reduced royalty rates, or a reduced installed device base using tape media cartridges, would result in further reductions in our royalty revenue and could reduce gross margins. This could materially and adversely affect our business, financial condition and results of operations.

Our branded software revenues are also dependent on many factors, including the success of competitive offerings, our ability to execute on our product roadmap and our effectiveness at marketing and selling our branded software solutions directly or through our channel partners. Disruptions to any one of these factors could reduce our branded software revenues which could adversely affect our business, financial condition and operating results.

Our OEM deduplication software revenues also depend on many factors, including the success of competitive offerings, our ability to execute on our product roadmap with our OEM deduplication software partners, the effort of our OEM deduplication software partners in marketing and selling the resulting products, the market acceptance of the resulting products and changes in the competitive landscape such as that which occurred with EMC’s purchase of Data Domain. Our relationship with EMC changed from partner to competitor in deduplication as a result of their acquisition of Data Domain. Following this acquisition, except for the first quarter of fiscal 2011 when significant revenue was recognized in accordance with contractual requirements, our OEM deduplication software revenue has significantly declined, which negatively impacted our results. Any further disruptions to the factors on which our OEM deduplication software revenues depends could adversely affect our business, financial condition and operating results.

We have taken considerable steps towards reducing our cost structure and may take further cost reduction actions. The steps we have taken and may take in the future may not reduce our cost structure to a level appropriate in relation to our future sales and therefore, these anticipated cost reductions may be insufficient to result in consistent profitability.

In the last several years, we have recorded significant restructuring charges and made cash payments in order to reduce our cost of sales and operating expenses to respond to adverse economic and industry conditions, from strategic management decisions and to rationalize our operations following acquisitions. We may take future steps to further reduce our operating costs, including future cost reduction steps or restructurings in response to strategic decisions, adverse changes in our business or industry or future acquisitions. We may be unable to reduce our cost of sales and operating expenses at a rate and to a level appropriate in relation to our future sales, which may adversely affect our business, financial condition and operating results.

If we are unable to attract and retain skilled employees, our business could be adversely impacted.

We may be subject to increased turnover in our employee base or the inability to fill open headcount requisitions due to competition, concerns about our operational performance or other factors. In addition, we may rely on the performance of employees whose skill sets are not sufficiently developed to fulfill their expected job responsibilities. Either of these situations could impair or delay our ability to realize operational and strategic objectives and cause increased expenses and lost sales opportunities.

Economic or other business factors may lead us to write down the carrying amount of our goodwill or long-lived assets, such as the goodwill impairment charge in fiscal 2009, which could have a material and adverse effect on our results of operations.

We evaluate our goodwill for impairment annually during the fourth quarter of our fiscal year, or more frequently when indicators of impairment are present. Long-lived assets are reviewed for impairment whenever events or circumstances indicate impairment might exist. We continue to monitor relevant market and economic conditions, including the price of our stock, and perform appropriate impairment reviews when conditions deteriorate such that we believe the value of our goodwill could be further impaired or an impairment exists in our long-lived assets. It is possible that conditions could deteriorate due to economic or other factors that affect our business, resulting in the need to write down the carrying amount of our goodwill or long-lived assets to fair value at the time of such assessment. As a result, our operating results could be materially and adversely affected.

Third party intellectual property infringement claims could result in substantial liability and significant costs, and, as a result, our business, financial condition and operating results may be materially and adversely affected.

From time to time, third parties allege our infringement of and need for a license under their patented or other proprietary technology, such as our current litigation with CTS Solutions and Overland Storage described in Legal Proceedings. While we currently believe the amount of ultimate liability, if any, with respect to any such actions will not materially affect our financial position, results of operations or liquidity, the ultimate outcome of any license discussion or litigation is uncertain. Adverse resolution of any third party infringement claim could subject us to substantial liabilities and require us to refrain from manufacturing and selling certain products. In addition, the costs incurred in intellectual property litigation can be substantial, regardless of the outcome. As a result, our business, financial condition and operating results could be materially and adversely affected.

In addition, certain products or technologies acquired or developed by us may include “open source” software. Open source software is typically licensed for use at no initial charge. Certain open source software licenses, however, require users of the open source software to license to others any software that is based on, incorporates or interacts with, the open source software under the terms of the open source license. Although we endeavor to comply fully with such requirements, third parties could claim that we are required to license larger portions of our software than we believe we are required to license under open source software licenses. If such claims were successful, they could adversely impact our competitive position and financial results by providing our competitors with access to sensitive information that may help them develop competitive products. In addition, our use of open source software may harm our business and subject us to intellectual property claims, litigation or proceedings in the future because:

As a result of our global manufacturing and sales operations, we are subject to a variety of risks that are unique to businesses with international operations of a similar scope, any of which could, individually or in the aggregate have a material adverse effect on our business.

A significant portion of our manufacturing and sales operations and supply chain occurs in countries other than the U.S. We also have sales outside the U.S. We utilize contract manufacturers to produce certain of our products and have suppliers for various components, several of which have operations located in foreign countries including China, Hungary, Japan, Malaysia, Singapore and Thailand. Because of these operations, we are subject to a number of risks including:

Our quarterly operating results could fluctuate significantly, and past quarterly operating results should not be used to predict future performance.

Our quarterly operating results have fluctuated significantly in the past and could fluctuate significantly in the future. As a result, our quarterly operating results should not be used to predict future performance. Quarterly operating results could be materially and adversely affected by a number of factors, including, but not limited to:

For instance, for the first quarter of fiscal 2013, our financial results were below our guidance for the period in part because we were unable to close a number of larger transactions. After we reported results on July 9, 2012, our share price declined by 28%. If we fail to meet our projected quarterly results, our business, financial condition and results of operations may be materially and adversely affected.

If we fail to protect our intellectual property or if others use our proprietary technology without authorization, our competitive position may suffer.

Our future success and ability to compete depends in part on our proprietary technology. We rely on a combination of copyright, patent, trademark, and trade secrets laws and nondisclosure agreements to establish and protect our proprietary technology. However, we cannot provide assurance that patents will be issued with respect to pending or future patent applications that we have filed or plan to file or that our patents will be upheld as valid or will prevent the development of competitive products or that any actions we have taken will adequately protect our intellectual property rights. We generally enter into confidentiality agreements with our employees, consultants, customers, potential customers and others as required, in which we strictly limit access to, and distribution of, our software, and further limit the disclosure and use of our proprietary information.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain or use our products or technology. Enforcing our intellectual property rights can sometimes only be accomplished through the use of litigation. Our competitors may also independently develop technologies that are substantially equivalent or superior to our technology. In addition, the laws of some foreign countries do not protect our proprietary rights to the same extent as the laws of the U.S.

Because we may order components from suppliers in advance of receipt of customer orders for our products that include these components, we could face a material inventory risk, which could have a material and adverse effect on our results of operations and cash flows.

Although we use third parties to manufacture certain of our products, we also manufacture products in-house. Managing our in-house manufacturing capabilities presents a number of risks that could materially and adversely affect our financial condition. For instance, as part of our component planning, we place orders with or pay certain suppliers for components in advance of receipt of customer orders. We occasionally enter into negotiated orders with vendors early in the manufacturing process of our products to ensure that we have sufficient components for our products to meet anticipated customer demand. Because the design and manufacturing process for these components can be complicated, it is possible that we could experience a design or manufacturing flaw that could delay or even prevent the production of the components for which we previously committed to pay. We also face the risk of ordering too many components, or conversely, not enough components, since supply orders are generally based on forecasts of customer orders rather than actual customer orders. In addition, in some cases, we make non-cancelable order commitments to our suppliers for work-in-progress, supplier’s finished goods, custom sub-assemblies, discontinued (end-of-life) components and Quantum-unique raw materials that are necessary to meet our lead times for finished goods. If we cannot change or be released from supply orders, we could incur costs from the purchase of unusable components, either due to a delay in the production of the components or other supplies or as a result of inaccurately predicting supply orders in advance of customer orders. These same risks exist with our third party contract manufacturing partners. Our business and operating results could be materially and adversely affected if we incur increased costs, or are unable to fulfill customer orders.

Some of our manufacturing, component production and service repair are outsourced to third party contract manufacturers, component suppliers and service providers. If we cannot obtain products, parts and services from these third parties in a cost effective and timely manner that meets our customers’ expectations, this could materially and adversely impact our business, financial condition and results of operations.

Many aspects of our supply chain and operational results are dependent on the performance of third party business partners. We face a number of risks as a result of these relationships, including, among others:

Any or all of these risks could have a material adverse effect on our business. In the past we have successfully transitioned products or component supply from one supplier to another existing supplier of different products or to our own facilities without significant financial or operational impact, but there is no guarantee of our continued ability to do so.

If we do not successfully manage the changes that we have made and may continue to make to our infrastructure and management, our business could be disrupted, and that could adversely impact our results of operations and financial condition.

Managing change is an important focus for us. In recent years, we have implemented several significant initiatives involving our sales and marketing, engineering and operations organizations, aimed at increasing our efficiency and better aligning these groups with our corporate strategy. In addition, we have reduced headcount to streamline and consolidate our supporting functions as appropriate in response to market or competitive conditions and following past acquisitions. Our inability to successfully manage the changes that we implement, and detect and address issues as they arise could disrupt our business and adversely impact our results of operations and financial condition.

Because we rely heavily on distributors and other resellers to market and sell our products, if one or more distributors were to experience a significant deterioration in its financial condition or its relationship with us, this could disrupt the distribution of our products and reduce our revenue, which could materially and adversely affect our business, financial condition and operating results.

In certain product and geographic segments we heavily utilize distributors and value added resellers to perform the functions necessary to market and sell our products. To fulfill this role, the distributor must maintain an acceptable level of financial stability, creditworthiness and the ability to successfully manage business relationships with the customers it serves directly. Under our distributor agreements with these companies, each of the distributors determines the type and amount of our products that it will purchase from us and the pricing of the products that it sells to its customers. If the distributor is unable to perform in an acceptable manner, we may be required to reduce the amount of sales of our product to the distributor or terminate the relationship. We may also incur financial losses for product returns from distributors or for the failure or refusal of distributors to pay obligations owed to us. Either scenario could result in fewer of our products being available to the affected market segments, reduced levels of customer satisfaction and/or increased expenses, which could in turn have a material and adverse impact on our business, results of operations and financial condition.

Our capital structure includes debt, which imposes upon us debt service obligations, and our credit facility contains various operating and financial covenants that limit our discretion in the operation of our business. If we are unable to generate sufficient cash flows from operations to meet these debt obligations or remain in compliance with the covenants, our business, financial condition and operating results could be materially and adversely affected.

Our level of indebtedness presents risks to investors, both in terms of the constraints that it places on our ability to operate our business and because of the possibility that we may not generate sufficient cash to pay the principal and interest on our indebtedness as it becomes due.

Our credit facility agreement contains restrictive covenants that require us to comply with and maintain certain financial tests and ratios, as well as restrict our ability, subject to certain thresholds, to:

Our ability to comply with covenants contained in this credit agreement may be affected by events beyond our control, including prevailing economic, financial and industry conditions.

Our credit facility agreement is collateralized by a pledge of all of our assets. If we were to default and were unable to obtain a waiver for such a default, the lender would have a right to foreclose on our assets in order to satisfy our obligations under the credit agreement. Any such action on the part of the lender against us could have a materially adverse impact on our business, financial condition and results of operations.

Our stock price could become more volatile if certain institutional investors were to increase or decrease the number of shares they own. In addition, there are other factors and events that could affect the trading prices of our common stock.

A small number of institutional investors have owned a significant portion of our common stock at various times in recent years. If any or all of these investors were to decide to purchase significant additional shares or to sell significant amounts or all of the common shares they currently own, or if there is a perception that those sales may occur, that may cause our stock price to be more volatile. For example, there have been instances in the past where a shareholder with a significant equity position began to sell shares, putting downward pressure on our stock price for the duration of their selling activity. In these situations, selling pressure outweighed buying demand and our stock price declined. This situation has occurred due to our stock price falling below institutional investors’ price thresholds and our volatility increasing beyond investors’ volatility parameters causing even greater sell pressure.

Trading prices of our common stock may fluctuate in response to a number of other events and factors, such as:

Any of these events and factors may cause our stock price to rise or fall and may adversely affect our business and financing opportunities.

Our design and production processes are subject to safety and environmental regulations which could lead to increased costs, or otherwise adversely affect our business, financial condition and results of operations.

We are subject to a variety of laws and regulations relating to, among other things, the use, storage, discharge and disposal of materials and substances used in our facilities and manufacturing processes as well as the safety of our employees and the public. Directives first introduced in the European Union impose a “take back” obligation on manufacturers for the financing of the collection, recovery and disposal of electrical and electronic equipment and restrict the use of certain potentially hazardous materials, including lead and some flame retardants, in electronic products and components. Other jurisdictions in the U.S. and internationally have since introduced similar requirements, and we anticipate that future regulations might further restrict allowable materials in our products, require the establishment of additional recycling or take back programs or mandate the measurement and reduction of carbon emissions into the environment. We have implemented procedures and will likely continue to introduce new processes to comply with current and future safety and environmental legislation. However, measures taken now or in the future to comply with such legislation may adversely affect our manufacturing or personnel costs or product sales by requiring us to acquire costly equipment or materials, redesign production processes or to incur other significant expenses in adapting our manufacturing programs or waste disposal and emission management processes. Furthermore, safety or environmental claims or our failure to comply with present or future regulations could result in the assessment of damages or imposition of fines against us, or the suspension of affected operations, which could have an adverse effect on our business, financial condition and results of operations.

We are subject to many laws and regulations, and violation of or changes in those requirements could materially and adversely affect our business.

We are subject to numerous U.S. and international laws regarding corporate conduct, fair competition, preventing corruption and import and export practices, including requirements applicable to U.S. government contractors. While we maintain a rigorous corporate ethics and compliance program, we may be subject to increased regulatory scrutiny, significant monetary fines or penalties, suspension of business opportunities or loss of jurisdictional operating rights as a result of any failure to comply with those requirements. We may also be exposed to potential liability resulting from our business partners’ violation of these requirements. In addition, U.S. regulatory agencies have recently introduced new enforcement efforts that may proactively seek conduct-related information from companies operating in certain targeted industries or locations, without regard for whether potential violations have been identified. If we were to receive such an information request, we may incur increased personnel and legal costs in order to adequately review and respond to the request. Further, our U.S. and international business models are based on currently applicable regulatory requirements and exceptions. Changes in those requirements or exceptions could necessitate changes to our business model. Any of these consequences could materially and adversely impact our business and operating results.

We face potential liability for performance problems of our products because our end users employ our storage technologies for the storage and backup of important data and to satisfy regulatory requirements. Although we maintain technology errors and omissions liability insurance, our insurance may not cover potential claims of this type or may not be adequate to indemnify us for all liability that may be imposed. Any imposition of liability or accrual of litigation costs that is not covered by insurance or is in excess of our insurance coverage could harm our business. In addition, we could potentially face claims for product liability from our customers if our products cause property damage or bodily injury. Although we maintain general liability insurance, our insurance may not cover potential claims of this type or may not be adequate to indemnify us for all liability that may be imposed. Any imposition of liability or accrual of litigation costs that is not covered by insurance or is in excess of our insurance coverage could harm our business.

We must maintain appropriate levels of service parts inventories. If we do not have sufficient service parts inventories, we may experience increased levels of customer dissatisfaction. If we hold excessive service parts inventories, we may incur financial losses.

We maintain levels of service parts inventories to satisfy future warranty obligations and also to earn service revenue by providing enhanced and extended warranty and repair service during and beyond the warranty period. We estimate the required amount of service parts inventories based on historical usage and forecasts of future warranty requirements, including estimates of failure rates and costs to repair, and out of warranty revenue. Given the significant levels of judgment inherently involved in the process, we cannot provide assurance that we will be able to maintain appropriate levels of service parts inventories to satisfy customer needs and to avoid financial losses from excess service parts inventories. If we are unable to maintain appropriate levels of service parts inventories, our business, financial condition and results of operations may be materially and adversely impacted.

From time to time we have made acquisitions. The failure to successfully integrate future acquisitions could harm our business, financial condition and operating results.

As a part of our business strategy, we have in the past and may make acquisitions in the future, subject to certain debt covenants. We may also make significant investments in complementary companies, products or technologies. If we fail to successfully integrate such acquisitions or significant investments, it could harm our business, financial condition and operating results. Risks that we may face in our efforts to integrate any recent or future acquisitions include, among others:

Acquisitions present many risks, and we may not realize the financial and strategic goals that were contemplated at the time of any transaction. We cannot provide assurance that we will be able to successfully integrate any business, products, technologies or personnel that we may acquire in the future, and our failure to do so could negatively impact our business, financial condition and operating results.

If the average closing price of our common stock were to drop below $1.00 per share over a consecutive thirty trading-day period, we would be out of compliance with NYSE Euronext (“NYSE”) rules, and our common stock could be delisted from trading on the NYSE, which could materially and adversely impair the liquidity and value of our common stock.

The price of our common stock has decreased during fiscal 2013, closing as low as $1.05 on October 31, 2012. If the average closing price of our common stock does not exceed $1.00 per share over a consecutive thirty trading-day period, we would be non-compliant with NYSE continued listing standards. Once notified of such non-compliance by the NYSE, we would need to bring our share price and consecutive thirty trading-day average share price back above $1.00 per share within six months or the NYSE would commence suspension and delisting procedures. In addition, if our common stock price falls below the $1.00 threshold to the point where the NYSE considers the stock price to be “abnormally low,” the NYSE has the discretion to begin delisting proceeding immediately with respect to our common stock. There is no formal definition of “abnormally low” in the NYSE rules. If our common stock were delisted, the ability of our stockholders to sell any of our common stock at all would be severely, if not completely, limited, causing our stock price to decline further.

If the future outcomes related to the estimates used in recording tax liabilities to various taxing authorities result in higher tax liabilities than estimated, then we would have to record tax charges, which could be material.

We have provided amounts and recorded liabilities for probable and estimable tax adjustments that may be proposed by various taxing authorities in the U.S. and foreign jurisdictions. If events occur that indicate payments of these amounts will be less than estimated, then reversals of these liabilities would create tax benefits recognized in the periods when we determine the liabilities have reduced. Conversely, if events occur which indicate that payments of these amounts will be greater than estimated, then tax charges and additional liabilities would be recorded. In particular, various foreign jurisdictions could challenge the characterization or transfer pricing of certain intercompany transactions. In the event of an unfavorable outcome of such challenge, there exists the possibility of a material tax charge and adverse impact on the results of operations in the period in which the matter is resolved or an unfavorable outcome becomes probable and estimable.

Certain changes in stock ownership could result in a limitation on the amount of net operating loss and tax credit carryovers that can be utilized each year. Should we undergo such a change in stock ownership, it would severely limit the usage of these carryover tax attributes against future income, resulting in additional tax charges, which could be material.

We are exposed to fluctuations in foreign currency exchange rates, and an adverse change in foreign currency exchange rates relative to our position in such currencies could have a materially adverse impact on our business, financial condition and results of operations.

We do not currently use derivative financial instruments for foreign currency hedging or speculative purposes. We have used in the past, and may use in the future, foreign currency forward contracts to hedge our exposure to foreign currency exchange rates. To the extent that we have assets or liabilities denominated in a foreign currency that are inadequately hedged or not hedged at all, we may be subject to foreign currency losses, which could be significant.

Our international operations can act as a natural hedge when both operating expenses and sales are denominated in local currencies. In these instances, although an unfavorable change in the exchange rate of a foreign currency against the U.S. dollar would result in lower sales when translated to U.S. dollars, operating expenses would also be lower in these circumstances. An increase in the rate at which a foreign currency is exchanged for U.S. dollars would require more of that particular foreign currency to equal a specified amount of U.S. dollars than before such rate increase. In such cases, and if we were to price our products and services in that particular foreign currency, we would receive fewer U.S. dollars than we would have received prior to such rate increase for the foreign currency. Likewise, if we were to price our products and services in U.S. dollars while competitors priced their products in a local currency, an increase in the relative strength of the U.S. dollar would result in our prices being uncompetitive in those markets. Such fluctuations in currency exchange rates could materially and adversely affect our business, financial condition and results of operations.

Our headquarters are located in San Jose, California. We lease facilities in North America, Europe and Asia Pacific. The following is a summary of the significant locations and primary functions of those facilities as of March 31, 2013:

On June 28, 2012, Overland Storage, Inc. (“Overland”) filed a patent infringement lawsuit against Quantum in the U.S. District Court for the Southern District of California, alleging that certain of its automated tape libraries fall within the scope of patents 6,328,766 and 6,353,581. Overland is seeking injunctive relief, as well as the recovery of unspecified monetary damages, including treble damages for willful infringement. We do not believe we infringe the Overland patents and we will defend ourselves vigorously. We do not believe there is a reasonable possibility that we will pay material damages related to this lawsuit.

On August 28, 2012, we filed a lawsuit against Overland in the U.S. District Court for the Southern District of California, for patent infringements of our patents 6,542,787; 6,498,771; 5,925,119 and 5,491,812 by the products in Overland’s NEO tape library and SnapServer product lines. We are seeking injunctive relief and the recovery of monetary damages.

On April 12, 2013, we filed a lawsuit against Overland in the U.S. District Court for the Southern District of California, for patent infringements of our patent 7,263,596 by the products in Overland’s SnapScale product lines. We are seeking injunctive relief and the recovery of monetary damages.

On September 12, 2011, Compression Technology Solutions LLC (“CTS”) filed a patent infringement lawsuit against a group of companies, consisting of Quantum, CA., Inc., EMC Corporation, Hewlett-Packard Company, International Business Machines Corp., NetApp, Inc. and Quest Software, Inc., in the U.S. District Court for the Eastern District of Missouri, alleging that certain unspecified products of the defendants, characterized as “deduplication software systems,” and, in the case of Quantum, including Quantum’s “DXi Series Deduplication software,” fall within the scope of patent 5,414,650. CTS was seeking injunctive relief, as well as the recovery of monetary damages, including treble damages for willful infringement. We do not believe we infringe the CTS patent; we believe that the CTS patent is invalid, and we defended ourselves vigorously. In April 2012, our motion to transfer venue was granted and the lawsuit was transferred to the U.S. District Court for the Northern District of California. On May 29, 2013, our motion for summary judgment was granted, with all of the asserted claims held invalid by the District Court, and the lawsuit against Quantum and the other defendants has been dismissed with prejudice.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

We offer a comprehensive range of solutions for data protection and big data management challenges that provide performance and value to end user customers of all sizes, from small businesses to multinational enterprises. We believe our combination of expertise, innovation and platform independence enables us to solve data protection and big data management issues more easily, cost-effectively and securely. We earn our revenue from the sale of products, systems and services through an array of channel partners and our sales force to reach end user customers of all sizes. Our products are sold under both the Quantum brand name and the names of various OEM customers. They include DXi^® deduplication systems for high speed recovery and reliability, Scalar^® tape automation products for disaster recovery and long-term data retention, StorNext^® data management software and appliances, Lattus™ object storage solutions for high-performance big data file sharing and archiving and vmPRO^™ solutions for protecting virtual machine data. We also offer cloud solutions for cloud-based backup, fast restore, data recovery and business continuity. In addition, we have the global scale and scope to support our worldwide customer base.

As a specialist providing end user customers with differentiated data protection and big data management solutions, our strategy is to continue to grow the independent channel for Quantum branded solutions and to increase revenue by offering products with superior performance and value. We have implemented a number of initiatives in an effort to drive branded revenue growth. One key initiative for fiscal 2013 was to increase revenue from our disk systems and software solutions products. Another key area of focus for fiscal 2013 was our marketing and awareness campaign. A third initiative was to continue to introduce new products and enhanced offerings in the significant growth markets of disk and software for the data protection and big data and archive markets as well as strategic enhancements and offerings in the tape automation market while continuing to provide service and support to new and existing customers.

We started fiscal 2013 with the objectives of increasing total revenue, having operating profit and generating cash from operations. These objectives assumed the market for tape automation systems and tape drives would be approximately the same as fiscal 2012 and the market for disk systems and software solutions would grow compared to fiscal 2012. We experienced difficult market conditions during fiscal 2013, especially for products and solutions based on tape technology. Market analysts estimated the overall demand in tape market decreased approximately 20% in the first half of fiscal 2013. During that period we had a 17% decline in our tape automation systems revenue which caused a significant negative impact to both total revenue and operating profit. In addition, our disk systems and software revenue decreased in the first quarter of fiscal 2013 as a result of economic weakness in Europe, and large orders decreased due to customer caution from economic uncertainty. During the second half of fiscal 2013, we believe there was continued weakness in the storage market as a result of economic uncertainty regarding the fiscal cliff in the U.S., and companies continued to be cautious with their purchasing decisions. We believe global economic conditions also caused end users to continue to reduce or delay spending, resulting in lower than expected sales, particularly in Asia and Europe, in the fourth quarter of fiscal 2013.

In the second quarter of fiscal 2013, we met our objective of increasing revenue for disk systems and software revenue for the quarter, achieving record revenue in this category. This revenue growth continued in the third quarter of fiscal 2013, increasing disk systems and software solutions revenue from the third quarter of fiscal 2012, ending fiscal 2013 with record annual revenue from disk systems and software solutions. We believe this revenue increase reflects the market opportunity, the strength of our DXi and StorNext product portfolios and continued innovation in these product families in addition to achieving better sales traction in the channel and improved sales productivity.

We expected and experienced sequential improvement in tape automation systems revenue from year-end IT budget spending and the release of LTO-6 technology in the third quarter of fiscal 2013. We introduced LTO-6 tape drives and tape automation systems in certain of our products in December 2012, which contributed to increased tape automation revenue from the second quarter of fiscal 2013 and sales of products with LTO-6 technology contributed incremental tape automation revenue in the fourth quarter of fiscal 2013 compared to the third quarter of fiscal 2013. Overall, we believe we retained our market share leadership in open tape systems automation due to the smaller percentage decrease in branded tape automation systems revenue than the estimated decrease in overall market demand. Branded tape automation revenue decreased 13% in fiscal 2013 while OEM tape automation revenue decreased 20%.

We continued our focus on training our sales team and engaging with channel partners to take advantage of sales opportunities across our portfolio. We had stronger new customer acquisition in fiscal 2013 than in fiscal 2012 which we believe was due in part to increased end user and channel partner awareness as a result of our marketing and awareness campaign in the first half of fiscal 2013. In addition, we introduced several new products for big data environments during fiscal 2013, including Lattus–X and Lattus–M, the first products in our object storage solutions family for big data environments, and several StorNext appliances. We also expanded our data protection product portfolio with the introduction of DXi6800, enhancements and upgrades to enterprise disk, vmPRO software and enterprise tape in addition to releasing our Q-Cloud solution for cloud backup and disaster recovery which leverages our DXi and vmPRO technology.

Given the tape revenue decrease in the first half of fiscal 2013 compared to the first half of fiscal 2012, its impact on operating profit, and the use of cash in operations, we recognized the need for and implemented cost controls and spending reductions in the third and fourth quarters of fiscal 2013. As a result, our financial performance in the third quarter of fiscal 2013 improved from the second quarter of fiscal 2013, contributing to decreased operating loss and generating cash from operations. These cost controls resulted in additional decreases in operating expenses and we generated more cash from operations in the fourth quarter of fiscal 2013 than the third quarter of fiscal 2013. The sequential improvement in our financial results in the third quarter of fiscal 2013 also reflects the leverage in our business model where revenue growth quickly leads to improved operating results.

We continued to improve our capital structure during fiscal 2013. We issued $70 million of convertible subordinated notes and amended the Wells Fargo credit agreement to decrease the line of credit and modify certain covenants with terms that are financially more beneficial and provide additional flexibility to run our business.

We believe our product portfolio is the strongest it has been since we became a systems company and that it positions us well to continue to add customers and increase revenue in the next fiscal year. We plan to continue to expand and improve our product and solution offerings, with emphasis on branded disk systems, software solutions, virtual offerings, cloud solutions and next generation object storage. Using a balanced approach to take advantage of market opportunities and investing for growth while in a period of economic uncertainty, we are focused on revenue growth balanced with operating profit and generating cash from operations.

We had total revenue of $587.6 million in fiscal 2013, a 10% decrease from fiscal 2012 primarily due to decreased market demand for products based on tape technology Product revenue from OEM customers decreased 18% and revenue from branded products decreased 10% both primarily due to decreased revenue from tape automation systems. Our continued efforts to increase revenue from disk systems and software solutions resulted in record annual revenue for this revenue category and a 4% increase from fiscal 2012. Service revenue was unchanged from fiscal 2012, while royalty revenue decreased 21% from fiscal 2012 as expected. Our focus on growing the branded business during the fiscal year is reflected in the greater proportion of non-royalty revenue from our branded business, at 83% in fiscal 2013, compared to 81% in fiscal 2012 and 79% in fiscal 2011.

Our gross margin percentage decreased 100 basis points from fiscal 2012 to 41.0% largely due to decreased product revenue and a corresponding lower product gross margin as well as a $12.2 million decrease in royalty revenue, partially offset by increased service gross margin. Some of our costs of goods sold are relatively fixed in the short term; therefore, revenue increases or decreases can have a material impact on the gross margin rate. Operating expenses increased $13.2 million, or 5% from fiscal 2012, primarily from restructuring charges in the second half of fiscal 2013 for severance and benefits to right-size our workforce in order to align spending with revised revenue expectations. We had a $42.7 million loss from operations in fiscal 2013 compared to operating income of $5.2 million in fiscal 2012.

Interest expense decreased 22% to $8.3 million primarily due to principal payments in the prior year and to a lesser extent from decreased debt amortization expense as a result of debt refinancings in calendar 2012. During fiscal 2013, we issued $70 million of subordinated convertible debt, using $49.5 million of the proceeds to fully repay the balance on the revolving credit line. We continued to generate cash from operating activities, with $7.7 million in fiscal 2013 compared to $45.7 million in fiscal 2012.

Total revenue in fiscal 2013 decreased from fiscal 2012, reflecting a decline in the tape automation market, economic uncertainty and a decrease in large orders, or orders over $200,000. These factors impacted revenue from branded data protection products and services the most, with a $39.8 million, or 9%, decrease from fiscal 2012. Data protection products include our tape automation systems, disk systems and devices and media offerings. The market for big data management and archive continued to grow, and revenue from branded big data and archive products and services increased 18%, or $7.8 million, from fiscal 2012, partially offsetting the decreased revenue from data protection products. Big data management and archive products include StorNext software, StorNext appliances and Lattus object storage solutions. In addition, OEM product and service revenue decreased $20.6 million, or 19%, and royalty revenue decreased $12.2 million, or 21%, from fiscal 2012.

Total revenue decreased in fiscal 2012 compared to fiscal 2011 primarily due to expected reductions in OEM and royalty revenue. The largest decreases in OEM revenue were from lower deduplication software, tape automation products, devices and service revenue. Partially offsetting these decreases were increased sales of branded disk systems and software solutions in fiscal 2012.

Product revenue decreased 12% from fiscal 2012, primarily due to decreased sales of tape automation systems followed by lower revenue from devices and media, partially offset by increased revenue from disk systems and software solutions. Revenue from sales of branded products decreased 10% and OEM product revenue decreased 18% in fiscal 2013 compared to fiscal 2012, both primarily due to lower sales of tape automation systems.

Our disk systems and software solutions revenue increased 4% from 2012, resulting in record annual revenue in this revenue category. Revenue increases were primarily from sales of our StorNext appliances leading to record revenue for branded software solutions, and we also had record revenue from sales of midrange DXi products. The first StorNext appliances were introduced in fiscal 2012 and we added a number of products to the StorNext appliance family during fiscal 2013. Revenue from midrange disk systems increased 11% from the prior year; however, we believe our midrange disk systems cannibalized some revenue from enterprise disk solutions due to the capabilities of our newest midrange disk product. We had lower enterprise disk system revenue primarily due to fewer large orders, or orders over $200,000, during fiscal 2013.

The decrease in tape automation systems revenue in fiscal 2013 compared to fiscal 2012 was due to approximately $20 million decreases in both branded and OEM tape automation system sales. Midrange tape automation sales decreased the most, with 15% and 17% decreases, respectively, of branded midrange and OEM midrange tape automation systems revenue. Enterprise systems and entry-level sales of tape automation systems had similar revenue decreases from fiscal 2012. As noted above, demand for tape automation products decreased approximately 20% during the first half of fiscal 2013. Revenue from OEM tape automation systems decreased 20% while branded tape automation systems revenue decreased 13%, an indication that we gained market share in the branded tape business during fiscal 2013.

Product revenue from devices and media, which includes tape drives, removable hard drives and non-royalty media, decreased as expected from fiscal 2012 largely due to decreased media sales in addition to lower revenue from devices. These revenue decreases were primarily due to overall market declines. Higher than typical media sales during fiscal 2012 due to inventories being increased in response to concerns of supply disruptions following the March 2011 earthquake and tsunami in Japan also contributed to the decreased media revenue in fiscal 2013 compared to the prior year.

Product revenue decreased slightly from fiscal 2011, primarily due to decreased sales of tape automation systems and devices and media, mostly offset by increased revenue from disk systems and software solutions. Revenue from sales of branded products increased 3% in fiscal 2012 compared to fiscal 2011 primarily due to increased sales of disk systems and software solutions.

We introduced new disk products, a new product line of StorNext appliances and released upgrades to both disk systems and to software solutions in fiscal 2012, all of which contributed to fiscal 2012 revenue. We continued our efforts to expand engagement with our channel partners to increase sales of disk systems and software solutions. Revenue from disk systems and software solutions increased 8% to $119.0 million in fiscal 2012 compared to fiscal 2011, primarily due to increased midrange disk product sales followed by the addition of StorNext appliances. Midrange disk systems revenue increases were primarily due to the addition of revenue from our DXi6701 and DXi6702 products. Tempering these increases was an expected decrease in OEM deduplication software revenue due to our primary OEM deduplication software customer becoming a competitor in fiscal 2010 and revenue recognized in accordance with contractual requirements in fiscal 2011 that was not repeated.

Tape automation systems sales decreased $9.1 million, or 4%, in fiscal 2012 compared to fiscal 2011. This decrease was primarily due to expected declines in OEM revenue, followed by decreased branded enterprise and entry-level tape automation systems revenue.

Product revenue from devices, including tape drives and removable hard drives, and non-royalty media sales decreased 5% to $87.3 million primarily due to anticipated decreases in sales of older branded and OEM device technologies that reached, or are nearing, end of life. Largely offsetting the decrease was an increase in branded media revenue primarily due to the March 2011 earthquake and tsunami in Japan and resulting concern of shortages and supply disruption in the market. We continue to be strategic with media sales and have chosen to not pursue opportunities that do not provide sufficient margins.

Service revenue includes revenue from sales of hardware service contracts, product repair, installation and professional services. Sales of hardware service contracts are typically purchased by our customers to extend the warranty or to provide faster service response time, or both. Service revenue was relatively unchanged in fiscal 2013 primarily due to a decreased volume of OEM product repair services that was offset by growth in revenue from branded service contracts associated with our StorNext appliances.

Service revenue decreased 4% to $144.4 million in fiscal 2012 compared to fiscal 2011 primarily due to lower hardware service contract revenues from end of service life on higher revenue service contracts for certain legacy branded tape automation products and to a lesser extent from decreased OEM product repair services. Service contracts on certain newer technology branded products provide lower revenue than service contracts on older technology branded products nearing end of service life. OEM service revenue decreases are primarily due to a number of our device products that reached end of service life in fiscal 2011 and fiscal 2012.

Tape media royalties decreased 21%, or $12.2 million, from fiscal 2012 due to lower media unit sales sold by media licensees, largely due to an expected decrease in market demand for LTO media. In addition, royalties from DLT media continued to decrease as expected due to many companies no longer choosing to use this older technology.

Royalty revenue declined 12%, or $7.6 million, in fiscal 2012 primarily due to expected decreases of maturing DLT media unit sales by media licensees. Royalties from LTO media decreased 4% in fiscal 2012 primarily due to decreased LTO media unit sales by media licensees.

* Fiscal 2012 total gross margin includes a $0.3 million restructuring benefit related to cost of revenue and fiscal 2011 total gross margin includes $0.6 million of restructuring charges related to cost of revenue.

The 100 basis point decrease in gross margin percentage compared to fiscal 2012 was primarily due to decreased product revenue and a corresponding lower product gross margin as well as a $12.2 million decrease in royalty revenue, partially offset by increased service gross margin. Some of our costs of goods sold are relatively fixed in the short term; therefore, revenue increases or decreases can have a material impact on the gross margin rate.

The 10 basis point decrease in gross margin percentage in fiscal 2012 compared to fiscal 2011 was due to largely offsetting factors. Gross margin decreased due to less high margin revenue in our product mix, largely from decreased OEM deduplication software revenue and royalty revenue. Both OEM deduplication software and royalty revenue provide among the highest margins of our portfolio. Gross margin was favorably impacted by lower intangible amortization from certain intangibles becoming fully amortized in fiscal 2011 and fiscal 2012.

Product gross margin dollars decreased $29.2 million, or 18%, compared to fiscal 2012, and our product gross margin rate decreased 270 basis points primarily due to a 12% decrease in product revenue. As noted above, some of our product costs of goods sold are relatively fixed in the short term; therefore, product revenue increases or decreases impact the product gross margin rate. The change in the mix of products sold, as described above in product revenue, also contributed to decreased product margins in fiscal 2013. In addition, we had an increase in compensation and benefits in fiscal 2013 compared to fiscal 2012 primarily due to investment in our software support team. We also had an increase in the manufacturing inventory allowance in fiscal 2013 compared to the prior year largely due to more products nearing end of life. Partially offsetting these factors was lower intangible amortization in fiscal 2013 due to certain intangible assets becoming fully amortized in fiscal 2013 and fiscal 2012, decreased facility expense from reducing our warehouse footprint and lower freight expense as a result of fewer shipments compared to fiscal 2012.

Product gross margin dollars decreased 1% in fiscal 2012 compared to fiscal 2011 primarily due to the 1% decrease in product revenue. However, product gross margin percentage improved slightly from fiscal 2011. The product gross margin increase was primarily due to a $7.1 million decrease in intangible amortization in fiscal 2012, mostly offset by the decrease in high margin OEM deduplication software revenue compared to fiscal 2011.

Service gross margin dollars increased $8.5 million, or 15%, compared to fiscal 2012, and service gross margin percentage increased 600 basis points while service revenue was unchanged. The increase in service margin was primarily due to reduced costs across our service delivery model from a decreased volume of repairs and in part due to bringing repair of certain product lines in-house. The more significant cost decreases in fiscal 2013 compared to fiscal 2012 were for compensation and benefits, external service providers, third party warehouse and service materials. Compensation and benefits decreased due to reduced staffing requirements from decreased repair volumes. External service provider expense decreased due to a combination of having repair of certain product lines in-house for the full fiscal year, decreased repair volumes and negotiating lower rates on the renewals of contracts with certain service providers in fiscal 2012. Third party warehouse expenses decreased due to efforts to reduce service parts inventory levels including reduced usage of third party warehouses. Service material decreases were primarily due to lower repair volumes compared to the prior year. In addition, our service activities continue to reflect a larger proportion of branded products under contract, which have relatively higher margins than margins for OEM repair services.

Service gross margin dollars decreased $0.9 million, or approximately 2%, in fiscal 2012 compared to fiscal 2011. Our service gross margin percentage increased 110 basis points to 38.7% in fiscal 2012, largely due to decreased external provider expenses and inventory allowance expense. External service provider expense decreased due to a combination of bringing repair of additional product lines in-house and negotiating lower rates on the renewals of contracts with certain service providers in fiscal 2012. We had higher inventory allowance expense in fiscal 2011 due to end of service life plans for several products. In addition, our service activities for fiscal 2012 reflected a greater proportion of revenue from branded products under contract, which have relatively higher margins than margins for OEM repair services.

The decrease in research and development expenses compared to fiscal 2012 was the net result of several factors. Due to the implementation of cost reduction measures in the second half of fiscal 2013, including restructuring actions that decreased headcount, we had a decrease of $0.8 million in compensation and benefits and also had smaller decreases in several other areas including travel expenses, dues and subscriptions and facilities expense. In addition, we had a $0.6 million decrease in project materials as a result of the types of products under development and related testing material requirements compared to the prior year. Mostly offsetting these decreases, we had a $0.9 million increase in depreciation expense due to laboratory testing equipment purchases and a $0.6 million increase in use of external service providers, primarily for next generation LTO product development.

The increase in research and development expenses for fiscal 2012 was primarily due to a $1.7 million increase in compensation and benefits from investment in our disk systems software and hardware and our virtual systems engineering teams to support new product development efforts. Partially offsetting this increase was a $0.5 million decrease in travel expenses compared to the prior year.

The increase in sales and marketing expense in fiscal 2013 compared to fiscal 2012 was primarily due to a $5.6 million increase in compensation and benefits from growing our branded sales force and marketing team in the first half of fiscal 2013. In addition, we had a $2.2 million net increase in advertising and marketing expenses and a $0.7 million increase in external service provider expense due to our awareness campaign and expanded advertising programs in the first half of fiscal 2013 intended to increase current and future demand for our products and services. As noted above, these efforts contributed to the stronger new customer acquisition in fiscal 2013. These increases were partially offset by a $3.6 million decrease in intangible amortization due to certain intangibles becoming fully amortized.

Sales and marketing expenses increased in fiscal 2012 primarily due to a $7.2 million increase in compensation and benefits, including commissions. Commissions increased due to increased branded product revenue and salaries and benefits increased largely due to growing our branded sales force. In addition, travel expenses increased $1.0 million due in part to increased airfare and fuel costs, incremental travel by our sales engineers to support customer sales and increased travel for sales training events to expand our position with existing and new channel partners to drive future growth.

The decrease in general and administrative expenses from fiscal 2012 was primarily due to a $0.8 million decrease in compensation and benefits from reduced headcount as a result of restructuring actions taken in the second half of fiscal 2013.

We may incur higher than typical legal costs in fiscal 2014 to defend ourselves while patent infringement lawsuits are ongoing. We do not believe there is a reasonable possibility that we will pay material damages related to these lawsuits. These lawsuits are discussed in more detail in Note 13 “Commitments and Contingencies” under Legal Proceedings.

The increase in general and administrative expenses was primarily due to a $2.2 million increase in compensation and benefits primarily from increased stock compensation expense due to equity grants related to promotions and merit increases. In addition, we had $1.4 million in credits in fiscal 2011 primarily due to accounts receivable recoveries and a litigation settlement that were not repeated.

Our restructuring actions are steps undertaken to reduce costs in an effort to return to consistent profitability. Given the tape revenue decrease in the first half of fiscal 2013, its impact on operating profit and the use of cash in operations, we recognized the need for and implemented restructuring plans in the second half of fiscal 2013. In fiscal 2011 and 2012, restructuring actions to consolidate operations supporting our business were the result of strategic management decisions. For additional information and disclosure of restructuring charges refer to Note 8 “Restructuring Charges” to the Consolidated Financial Statements. Until we achieve consistent and sustainable levels of profitability, we may incur restructuring charges in the future from additional cost reduction efforts.

The increase in restructuring charges in fiscal 2013 compared to the prior year was primarily due to a $6.7 million increase in severance and benefits expense from eliminating more positions in both the U.S. and internationally across most functions of the business to align spending with revenue expectations. Facility restructuring expense increased $1.6 million compared to fiscal 2012 primarily due to accruing remaining lease expense related to the portion of a U.S. facility that was vacated in the fourth quarter of fiscal 2013.

The decrease in restructuring charges in fiscal 2012 was due to a $2.0 million decrease in severance charges due to fewer positions eliminated during the year as a result of strategic management decisions and a $0.9 million decrease in restructuring charges related to cost of revenue due to lower actual costs than estimated to exit a supplier relationship. Partially offsetting these decreases was a $0.9 million increase in facility restructuring charges due to negotiating a $0.3 million settlement for a lease liability on a vacated facility in India in fiscal 2012 and $0.6 million in credits in fiscal 2011 primarily due to negotiating settlements for lease liabilities for amounts lower than the outstanding lease contracts.

During fiscal 2012, we had a $1.5 million gain on the sale of patents. Under the patent sale agreement, we retain a royalty-free license for these patents. We may enter into similar transactions in the future.

Other expense in fiscal 2013 was relatively unchanged from fiscal 2012. Other income and expense decreased $1.3 million in fiscal 2012 compared to fiscal 2011 primarily due to a $1.6 million net decrease in investment gains from fiscal 2011, largely due to gains from private technology venture limited partnerships that were not repeated. In addition, we had a $0.4 million net increase in foreign exchange losses primarily due to the U.S. dollar strengthening against the euro in fiscal 2012. These were partially offset by $0.9 million in fees for an amendment to our senior secured credit agreement in fiscal 2011 that were not repeated.

Interest expense decreased from fiscal 2012 primarily due to principal payments in the prior year that reduced the outstanding debt balance in fiscal 2013 compared to fiscal 2012. We also had a lower average interest rate during fiscal 2013 than the prior year that contributed to decreased interest expense. In addition, the debt refinancing in March 2012 to a revolving credit facility that had lower debt issuance costs than the prior credit facility decreased amortization of debt issuance costs in fiscal 2013 compared to fiscal 2012.

Interest expense decreased in fiscal 2012 compared to fiscal 2011 primarily due to decreased average interest rates from refinancing subordinated term debt that had a 12% interest rate with 3.5% convertible subordinated notes issued in November 2010. In addition, we had a lower senior secured term debt balance in fiscal 2012 than fiscal 2011 which also contributed to decreased interest expense.

In addition to the items noted above, interest expense includes the amortization of debt issuance costs for debt facilities. For further information, refer to Note 7 “Convertible Subordinated Debt and Long-Term Debt” to the Consolidated Financial Statements.

During the fourth quarter of fiscal 2012, we fully repaid our senior secured term loan with Credit Suisse using cash on hand and borrowings of $49.5 million from a new credit facility with Wells Fargo. In connection with this debt extinguishment, we wrote off $2.3 million of unamortized debt costs related to the Credit Suisse credit agreement.

During the third quarter of fiscal 2011, we fully repaid outstanding subordinated term loans by issuing $135 million aggregate principal of 3.50% convertible subordinated notes. In connection with this debt extinguishment, we wrote off $1.2 million of unamortized debt costs related to the subordinated term loans.

The $0.3 million increase in tax expense in fiscal 2013 compared to fiscal 2012 was primarily due to higher foreign taxes. The $0.9 million increase in tax expense in fiscal 2012 compared to fiscal 2011 was primarily due to the release in fiscal 2011 of $0.9 million in tax liabilities in foreign jurisdictions that were not repeated. Tax expense in fiscal 2013 and fiscal 2012 was primarily comprised of foreign income taxes and state taxes. Tax expense in fiscal 2011 was primarily comprised of foreign income taxes and state taxes, offset by the release of tax liabilities in foreign jurisdictions due to a favorable settlement and expiration of statutes of limitation.

The following table details intangible asset amortization expense by classification within our Consolidated Statements of Operations (in thousands):

The decreased intangible asset amortization in fiscal 2013 and 2012 compared to the respective prior years was due to certain intangible assets becoming fully amortized. Refer to Note 5 “Intangible Assets and Goodwill” to the Consolidated Financial Statements for further information regarding our amortizable intangible assets.

The following table summarizes share-based compensation within our Consolidated Statements of Operations (in thousands):

The increase in share-based compensation in fiscal 2013 was primarily due to $2.5 million of incremental RSU expense largely for merit awards granted in 2013 to sales and marketing and research and development team members. This increase was partially offset by a $0.9 million decrease in option expense from fiscal 2012 due to existing options becoming fully vested during fiscal 2013 and a $0.2 million decrease in expense related to the employee stock purchase plan (“ESPP”) due to lower stock prices than fiscal 2012.

The increase in share-based compensation expense in fiscal 2012 compared to fiscal 2011 was primarily due to a $3.7 million increase in expense related to restricted stock units due to more restricted stock units granted for employee merit increases at a higher grant-date stock price in fiscal 2012 than fiscal 2011. In addition we had a $0.6 million increase in expense related to the ESPP due to increased participation in fiscal 2012. This was partially offset by a $1.0 million decrease in expense related to options due to more options vesting in fiscal 2012 than were replaced by new option grants.

See Recent Accounting Pronouncements in Note 2 “Summary of Significant Accounting Policies” to the Consolidated Financial Statements for a full description of recent accounting pronouncements including the respective expected dates of adoption and effects on our results of operations and financial condition.

The $60.2 million difference between reported net loss and cash provided by operating activities during fiscal 2013 was primarily due to $52.1 million in non-cash items, the largest of which were share-based compensation, amortization, depreciation and service parts lower of cost or market adjustment. In addition, we had an $11.7 million decrease in accounts receivable primarily due to lower revenue and service billings in the fourth quarter of fiscal 2013 than the fourth quarter of fiscal 2012. This was partially offset by an $8.6 million decrease in accounts payable primarily due to decreased purchases and the timing of payments.

Cash used in investing activities was primarily due to $10.1 million of property and equipment purchases and $2.2 million used to purchase other investments. Equipment purchases were primarily for engineering equipment and testing hardware to support product development activities and equipment to update our network. We also made leasehold improvements to a location we started leasing in the first quarter of fiscal 2013. Other investment purchases we made were in private technology companies with products or features complementary to Quantum products and our strategy.

Cash provided by financing activities during fiscal 2013 was primarily due to $18.2 million in net borrowings from issuing convertible subordinated debt and repaying our line of credit balance from a portion of the convertible debt proceeds. In addition, we received $4.8 million from the exercise of stock options and issuance of shares under the employee stock purchase plan, partially offset by $2.0 million paid for taxes due upon vesting of restricted stock.

The $54.5 million difference between reported net loss and cash provided by operating activities in fiscal 2012 was primarily due to $60.4 million of non-cash expenses, including amortization, share-based compensation, depreciation and service parts lower of cost or market adjustment. In addition, we had an $8.1 million increase in deferred revenue primarily due to increased sales of service contracts. Partially offsetting these was a $21.4 million use of cash from increased manufacturing inventories primarily due to purchasing materials to build and configure new products and securing hard disk drives in light of supply constraints from flooding in Thailand earlier in the fiscal year.

Cash used in investing activities during fiscal 2012 was primarily due to $11.4 million in purchases of property and equipment and $8.2 million of cash paid, net of cash acquired, for our acquisition of Pancetera. Equipment purchases were primarily for engineering equipment and testing hardware to support product development activities.

Cash used in financing activities during fiscal 2012 was primarily due to net debt repayments of $55.8 million, including $104.3 million to fully repay our senior secured term debt. We refinanced a portion of the senior secured term debt with a new revolving credit facility in fiscal 2012. Partially offsetting cash used in financing activities was $10.4 million in proceeds received from the exercise of stock options and issuance of shares under the employee stock purchase plan.

The $47.8 million difference between reported net income and cash provided by operating activities in fiscal 2011 was primarily due to $67.5 million of non-cash expenses, including amortization, service parts lower of cost or market adjustment, depreciation and share-based compensation. These noncash expenses were partially offset by a $14.9 million increase in accounts receivable primarily due to increased sales of products and service billings in the fourth quarter of fiscal 2011 compared to the fourth quarter of fiscal 2010.

Cash used in investing activities during fiscal 2011 was primarily due to $12.3 million in purchases of property and equipment. Equipment purchases were primarily for engineering test equipment to support product development activities.

Cash used in financing activities during fiscal 2011 was primarily due to net debt repayments of $95.5 million, including $81.7 million of principal on our senior secured term debt. We refinanced subordinated term loans with 3.50% convertible subordinated debt in fiscal 2011, and the repayment of this long-term debt was offset by borrowings of convertible subordinated debt. In addition, we received $16.5 million from the issuance of common stock.

We continue to focus on improving our operating performance, including efforts to increase revenue and to continue to control costs in order to improve margins, return to consistent profitability and generate positive cash flows from operating activities. We believe that our existing cash and capital resources will be sufficient to meet all currently planned expenditures, debt service, contractual obligations and sustain operations for at least the next 12 months. This belief is dependent upon our ability to achieve gross margin projections and to control operating expenses in order to provide positive cash flow from operating activities. Should any of the above assumptions prove incorrect, either in combination or individually, it would likely have a material negative effect on our cash balances and capital resources.

The following is a description of our existing capital resources including outstanding balances, funds available to borrow, and primary repayment terms including interest rates. For additional information, see Note 7 “Convertible Subordinated Debt and Long-Term Debt” to the Consolidated Financial Statements.

We have $205 million of convertible subordinated debt in addition to a line of credit under the Wells Fargo Credit agreement (“WF credit agreement”). The $135 million aggregate principal amount outstanding of 3.50% convertible subordinated notes is due November 15, 2015, the terms of which are governed by an agreement dated November 15, 2010 between Quantum and U.S. Bank National Association (“3.50% notes”). The $70 million aggregate principal amount outstanding of 4.50% convertible subordinated notes further described below is due November 15, 2017, the terms of which are governed by an agreement dated October 31, 2012 between Quantum and U.S. Bank National Association (“4.50% notes”). Both the 3.50% notes and the 4.50% notes have required semi-annual interest payments.

During the third quarter of fiscal 2013, we issued $70 million aggregate principal amount of convertible subordinated notes. This was comprised of $60 million aggregate principal amount issued on October 31, 2012, and an additional $10 million aggregate principal amount issued on November 6, 2012 pursuant to an over-allotment provision. These notes are convertible into shares of our common stock at a conversion rate of 607.1645 shares per $1,000 principal amount, a conversion price of approximately $1.65 per share. We may not redeem the notes prior to their maturity date although investors may convert the 4.50% notes into Quantum common stock until November 14, 2017 at their option. In addition, since purchasers are qualified institutional investors, as defined in Rule 144A under the Securities Act of 1933 (“Securities Act”), the 4.50% notes have not been registered under the Securities Act. We pay 4.50% interest per annum on the principal amount of the 4.50% notes semi-annually on May 15 and November 15 of each year beginning in May 2013. Interest began to accrue on October 31, 2012. The 4.50% notes are subordinated to any existing indebtedness and other liabilities. We incurred and capitalized $2.3 million of fees for the 4.50% notes which are included in other long-term assets in our Consolidated Balance Sheets. The fees are amortized to interest expense over the term of the notes.

Under the WF credit agreement, as amended, we have the ability to borrow under a senior secured revolving credit facility. The maximum borrowing amount is the lesser of $55 million or the amount of the monthly borrowing base. The WF credit agreement matures March 29, 2017, or on August 16, 2015 if our 3.50% notes remain outstanding on that date. Quarterly, we are required to pay a 0.375% commitment fee on undrawn amounts under the revolving credit facility. There is a blanket lien on all of our assets under the WF credit agreement in addition to certain financial and reporting covenants. On October 31, 2012, we repaid all outstanding borrowings under the WF credit agreement with $49.5 million of the proceeds from the 4.50% notes. We have letters of credit totaling $1.1 million, reducing the amount available to borrow to $53.9 million at March 31, 2013. As of March 31, 2013, we were in compliance with all covenants and had no outstanding balance on the line of credit.

There were two primary amendments made to the WF credit agreement during fiscal 2013. On June 28, 2012, the WF credit agreement was amended in order to allow the assignment of one third of the total revolver commitment to Silicon Valley Bank. This amendment also made certain other conforming and related modifications, including changes to the average liquidity requirements.

With the completion of the convertible debt offering in the third quarter of fiscal 2013, we requested an amendment to the WF credit agreement to decrease the line of credit and modify certain covenants. An amendment was completed on January 31, 2013. The average liquidity covenant was eliminated. The fixed charge coverage ratio covenant is applicable only in fiscal quarters in which liquidity is below $16.5 million and decreased from 1.2 to 1.1 for the 12 month period ending on the last day of any fiscal quarter in which the covenant is applicable. The liquidity requirement to avoid triggering mandatory field audits decreased from $20 million to $18.5 million commencing January 31, 2013 and will remain at this level for the remaining term of the credit agreement. Both the fixed charge coverage ratio and liquidity are defined in the WF credit agreement and the January 31, 2013 amendment. In addition, compliance certificates must be filed monthly if borrowings exceed $15 million, otherwise they are to be filed quarterly. The fixed charge coverage ratio was not applicable for the fourth quarter of fiscal 2013 because our liquidity level exceeded the contractual threshold.

Generation of positive cash flow from operating activities has historically been, and will continue to be, an important source of cash to fund operating needs and meet our current and long-term obligations. We have taken many actions in recent years to offset the negative impact of economic uncertainty and slow economic growth and their impact on the data protection and big data and archive markets. We implemented cost reduction initiatives in the third quarter of fiscal 2013 and additional spending control programs in the fourth quarter of fiscal 2013 in an effort to better align spending with revenue expectations. We cannot provide assurance that the actions we are currently undertaking, have taken in the past or any actions we may take in the future will ensure a consistent, sustainable and sufficient level of net income and positive cash flow from operating activities to fund, sustain or grow our business. Certain events that are beyond our control, including prevailing economic, competitive and industry conditions, as well as various legal and other disputes, may prevent us from achieving these financial objectives. Any inability to achieve consistent and sustainable net income and cash flow could result in:

Any of the above mentioned items, individually or in combination, could have a material and adverse effect on our results of operations, available cash and cash flows, financial condition, access to capital and liquidity.

We lease certain facilities under non-cancelable lease agreements. Some of the leases have renewal options ranging from one to ten years and others contain escalation clauses and provisions for maintenance, taxes or insurance. We also have equipment leases for computers and other office equipment. Future minimum lease payments under these operating leases are shown below in the “Contractual Obligations” section.

We use contract manufacturers for certain manufacturing functions. Under these arrangements, the contract manufacturer procures inventory to manufacture products based upon our forecast of customer demand. We have similar arrangements with certain other suppliers. We are responsible for the financial impact on the supplier of any reduction or product mix shift in the forecast relative to materials that the supplier had already purchased under a prior forecast. Such a variance in forecasted demand could require a cash payment for inventory in excess of current customer demand or for costs of excess or obsolete inventory. As of March 31, 2013, we had issued non-cancelable purchase commitments for $22.3 million to purchase inventory from our suppliers.

As of March 31, 2013, there was $87.9 million remaining under our authorization to repurchase Quantum common stock. No stock repurchases were made during the fiscal years ended March 31, 2013, 2012 and 2011. Our ability to repurchase our common stock is restricted unless we meet certain thresholds under the terms of the WF credit agreement.

The table below summarizes our contractual obligations as of March 31, 2013 (in thousands):

The contractual commitments shown above include $29.9 million in interest payments on our various debt obligations. As of March 31, 2013, we had $5.1 million of long-term tax liabilities for uncertain tax positions, for which we cannot make a reasonably reliable estimate of when payments are likely to occur.

Our discussion and analysis of the financial condition and results of operations is based on the accompanying Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these statements requires us to make significant estimates and judgments about future uncertainties that affect reported assets, liabilities, revenues and expenses and related disclosures. We base our estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. Our significant accounting policies are presented within Note 2 to the Consolidated Financial Statements. Our critical accounting estimates require the most difficult, subjective or complex judgments and are described below. An accounting estimate is considered critical if it requires estimates about the effect of matters that are inherently uncertain when the estimate is made, if different estimates reasonably could have been used or if changes in the estimate that are reasonably possible could materially impact the financial statements. We have discussed the development, selection and disclosure of our critical accounting policies with the Audit Committee of our Board of Directors. We believe the assumptions and estimates used and the resulting balances are reasonable; however, actual results may differ from these estimates under different assumptions or conditions.

Application of the various accounting principles related to measurement and recognition of revenue requires us to make judgments and estimates in the following related areas: determining estimated selling prices (“ESP”) and allocating revenue based on the relative selling prices in arrangements with multiple deliverables, including assessing whether we have vendor-specific objective evidence (“VSOE”) or third-party evidence of selling price (“TPE”) for each deliverable; the interpretation of non-standard terms and conditions in sales agreements; assessments of future price adjustments, such as rebates, price protection and future product returns and estimates for contractual licensee fees.

When we enter into sales arrangements with customers that contain multiple deliverables such as hardware, software and services, these arrangements require us to identify each deliverable and determine its ESP following the relative selling price hierarchy. Additionally, we sometimes use judgment in order to determine the appropriate timing of revenue recognition and to assess whether any software and nonsoftware components function together to deliver a tangible product’s essential functionality in order to ensure the arrangement is properly accounted for as software or hardware revenue.

When we enter into multiple deliverable revenue arrangements with customers which are not subject to software revenue guidance, we use judgment to (1) separate the deliverables based on specific criteria, (2) assign an estimated selling price to each deliverable based on the selling price hierarchy using VSOE, TPE or ESP and (3) allocate the total arrangement consideration using the relative selling price method. When VSOE cannot be established we attempt to establish the selling price of each element based on TPE. TPE is determined based on competitor prices for largely interchangeable products when sold separately. When we are unable to establish selling price using VSOE or TPE, we use ESP. We use judgment to determine ESP, which is the price at which we would transact a sale if the product or service were regularly sold on a standalone basis. In this determination we consider our discounting and internal pricing practices, external market conditions and competitive positioning for similar offerings.

While the majority of our sales arrangements contain standard terms and conditions, we sometimes apply judgment when interpreting complex arrangements with non-standard terms and conditions to determine the appropriate accounting and timing of revenue recognition. An example of such a judgment is deferring revenue related to significant post-delivery obligations and customer acceptance criteria until such obligations are fulfilled.

We license certain software to customers under licensing agreements that allow those customers to embed the software into specific products they offer. As consideration, licensees pay us a fee based on the amount of sales of their products that incorporate our software. On a periodic and timely basis, the licensees provide us with reports listing their sales to end users for which they owe us license fees. Similarly, royalty revenue is estimated from licensee reports of units sold to end users subject to royalties under master contracts. In both cases, these reports are used to substantiate delivery and we recognize revenue based on the information in these reports or when amounts can be reasonably estimated.

Our manufacturing and service parts inventories are stated at the lower of cost or market, with cost computed on a first-in, first-out (“FIFO”) basis. Adjustments to reduce the carrying value of both manufacturing and service parts inventories to their net realizable value are made for estimated excess, obsolete or impaired balances. Factors influencing these adjustments include significant estimates and judgments about the future of product life cycles, product demand, rapid technological changes, development plans, product pricing, physical deterioration, quality issues, end of service life plans and volume of enhanced or extended warranty service contracts.

We apply judgment when reviewing amortizable intangible and other long-lived assets (“long-lived assets”) and goodwill for impairment, including when evaluating potential impairment indicators. Indicators we consider include adverse changes in the economy or business climate that could affect the value of our long-lived assets or goodwill, overall financial performance such as negative or declining cash flows or operating income, changes in our business strategy, product mix or to the long-term economic outlook, a sustained decrease in our stock price and, in the case of goodwill, testing long-lived assets for recoverability. In addition, we evaluate on the basis of the weight of evidence the significance of identified events and circumstances along with how they could affect the relationship between the reporting unit's fair value and carrying amount, including positive mitigating events and circumstances.

We use an undiscounted cash flow approach to evaluate our long-lived assets for recoverability when there are impairment indicators. Estimates of future cash flows require significant judgments about the future and include company forecasts and our expectations of future use of our long-lived assets, both of which may be impacted by market conditions. Other critical estimates include determining the asset group or groups within our long-lived assets, the primary asset of an asset group and the primary asset’s useful life. During fiscal 2013, we early adopted the accounting guidance that allows entities the option to perform a qualitative assessment to determine whether it is more likely than not an indefinite-lived asset is impaired.

In addition to comparing the carrying value of the reporting unit to its fair value, because we have negative book value, we perform a qualitative analysis to determine whether it is not more likely than not that the fair value of goodwill is less than its carrying amount. If we determine it is more likely than not that the fair value of goodwill is less than its carrying amount, then a second step must be performed to quantify the amount of goodwill impairment, if any, requiring additional assumptions and judgments.

If the second step of a goodwill impairment test is required, the following assumptions and estimates may be used by management in an income approach analysis. We derive discounted cash flows using estimates and assumptions about the future. Other significant assumptions may include: expected future revenue growth rates, operating profit margins, working capital levels, asset lives used to generate future cash flows, a discount rate, a terminal value multiple, income tax rates and utilization of net operating loss tax carryforwards. These assumptions are developed using current market conditions as well as internal projections. Inherent in our development of cash flow projections for the income approach used in an impairment test are assumptions and estimates derived from a review of our operating results, approved business plans, expected growth, cost of capital and income tax rates. We also make certain assumptions about future economic conditions, applicable interest rates and other market data.

We estimate future product failure rates based upon historical product failure trends as well as anticipated future failure rates if believed to be significantly different from historical trends. Similarly, we estimate future costs of repair based upon historical trends and anticipated future costs if they are expected to significantly differ, for example due to negotiated agreements with third parties. We use a consistent model and exercise considerable judgment in determining the underlying estimates. Our model requires an element of subjectivity for all of our products. For example, historical return rates are not completely indicative of future return rates and we must therefore exercise judgment with respect to future deviations from our historical return rates. When actual failure rates differ significantly from our estimates, we record the impact in subsequent periods and update our assumptions and forecasting models accordingly. As our newer products mature, we are able to improve our estimates with respect to these products.

A number of estimates and judgments are necessary to determine deferred tax assets, deferred tax liabilities and valuation allowances. We recognize the benefit from a tax position only if it is more-likely-than-not that the position would be sustained upon audit based solely on the technical merits of the tax position. The calculation of our tax liabilities requires judgment related to uncertainties in the application of complex tax regulations. It is inherently difficult and subjective to estimate such amounts, as we have to determine the probability of various possible outcomes. We reevaluate these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity.

We have provided a full valuation allowance against our U.S. net deferred tax assets due to our history of net losses, difficulty in predicting future results and our conclusion that we cannot rely on projections of future taxable income to realize the deferred tax assets. In addition, we have provided a full valuation allowance against certain of our international net deferred tax assets. Due to reorganizations in these jurisdictions, it is unclear whether we will be able to realize a benefit from these deferred tax assets. Also, certain changes in stock ownership could result in a limitation on the amount of net operating loss and tax credit carryovers that can be utilized each year. Should we undergo such a change in stock ownership, it would severely limit the usage of these carryover tax attributes against future income, resulting in additional tax charges.

Significant management judgment is required in determining our deferred tax assets and liabilities and valuation allowances for purposes of assessing our ability to realize any future benefit from our net deferred tax assets. We intend to maintain this valuation allowance until sufficient evidence exists to support the reversal of the valuation allowance. Future income tax expense will be reduced to the extent that we have sufficient evidence to support a reversal or decrease in this allowance. We also have deferred tax assets and liabilities due to prior business acquisitions with corresponding valuation allowances after assessing our ability to realize any future benefit from these acquired net deferred tax assets.

Fair Value of Assets Acquired and Liabilities Assumed in a Business Combination

We use judgment when applying the various accounting principles to measure the fair value of assets acquired and liabilities assumed in a business combination. There are matters that are inherently uncertain when making estimates used to determine fair value where there are not active markets for these assets and liabilities. In addition, different estimates reasonably could be used and changes in the estimate that are reasonably possible could materially impact the resulting valuation and the financial statements. For example, judgments have been required to determine fair values of amortizable intangible assets, in-process research and development and the resulting amount of goodwill. Significant estimates and assumptions we make to estimate fair value of these acquired assets include:

In addition, the estimated future life of purchased technology intangibles impacts future financial statements. We believe the assumptions and estimates used and the resulting fair values are reasonable.

Changes in interest rates affect interest income earned on our cash equivalents. In addition, changes in interest rates affect interest expense on outstanding borrowings under the WF credit agreement and in fiscal 2012 affected interest expense on borrowings under the Credit Suisse credit agreement. Our convertible subordinated notes have fixed interest rates, thus a hypothetical 100 basis point increase in interest rates would not impact interest expense on these borrowings.

Our cash equivalents consisted solely of money market funds during fiscal 2013 and fiscal 2012. During fiscal 2013 and fiscal 2012, interest rates on these funds were under 1.0%, and we earned negligible amounts in interest income.

At March 31, 2013 we had no outstanding borrowings with variable interest rates, thus a hypothetical 100 basis point increase in interest rates would not impact interest expense.

During fiscal 2012, interest accrued on our CS credit agreement at our option, based on either, a prime rate plus a margin of 2.5%, or a LIBOR rate plus a margin of 3.5%, and the interest rate on amounts borrowed on our WF credit agreement was based on an election by us of an annual rate equal to (1) a base rate established by Wells Fargo plus an applicable margin of 1.0% to 1.5%, based on availability levels under the WF credit agreement or (2) the LIBOR rate plus an applicable margin ranging from 2.0% and 2.5%, based on availability levels under the WF credit agreement. A hypothetical 100 basis point increase in interest rates would have increased interest expense $0.2 million in fiscal 2012.

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of comprehensive income (loss), of cash flows, and of stockholders' deficit present fairly, in all material respects, the financial position of Quantum Corporation and its subsidiaries at March 31, 2013 and March 31, 2012, and the results of their operations and their cash flows for each of the three years in the period ended March 31, 2013 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2013, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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 (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 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 (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.

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.
