PART I

Westell Technologies, Inc., (the “Company”) was incorporated in Delaware in 1980 and is headquartered at 750 North Commons Drive, Aurora, Illinois 60504. The Company is comprised of three operating segments: Customer Networking Solutions (“CNS”) equipment, Outside Plant Systems (“OSPlant Systems” or “OSP”) equipment and ConferencePlus services segment. Segment financial information for fiscal years 2011, 2010 and 2009 is set forth in the footnotes to the March 31, 2011 consolidated financial statements.

CNS Segment

On March 17, 2011, the Company entered into a definitive agreement to sell certain assets and transfer certain liabilities of the CNS segment to NETGEAR, Inc. (“NETGEAR”) for $33.5 million in cash, subject to certain post-closing adjustments. This transaction closed on April 15, 2011. The Company retained a certain major CNS customer relationship and contract, and also retained the Homecloud product development program. Since the sale closed subsequent to our fiscal year ended March 31, 2011, the discussion of CNS in this section includes the entire year results of CNS, unless the context indicates otherwise.

In the CNS segment, the Company designs, distributes, markets and services a broad range of carrier-class broadband products. The CNS family of broadband products enables high-speed transport and networking of voice, data, video, and other advanced services. The products allow service providers to deliver services, content, and applications over existing copper, fiber, coax, and wireless infrastructures. Westell CNS products are typically installed in consumer residences or small businesses as a key component of a broadband service package.

CNS Products. The Company’s CNS products enable residential customers, small businesses, and small office/home office (“SOHO”) users to access and share broadband services on networked computers, telephones, cell phones, televisions, media players, and other networked devices. A broad offering of networking products and technologies allows the Company to address several segments of the service provider market, distinguished by the methods used to deliver their services: wireline operators (copper and fiber), cable multi-service operators (hybrid fiber-coax), and integrated carriers that operate as combinations of the other three operators.

OSP Segment

In the OSP segment, the Company designs, distributes, markets and services a broad range of carrier-class digital transmission, remote monitoring, power distribution, next-generation outdoor equipment cabinets and service provider demarcation products. The Company’s OSP products offer next-generation outdoor cabinets, enclosures, power distribution panels, flexible edge connectors (with respect to fiber, Ethernet and coax), remote monitoring solutions, DS1 and DS3 transmission plugs, and carrier grade Ethernet solutions. These solutions are optimized for wireline backhaul of cellular traffic, service delivery to business enterprise and smart grid applications. The Company’s OSP segment also provides a value-added Customized Systems Integration (“CSI”) service, offering customers a single source for complete turnkey solutions, reducing the time-to-market and expenses incurred through third-party contractors and eliminating the need to design, assemble and test on the job site. Target OSP customers include wireline service providers, wireless service providers, multiple systems operators (“MSOs”), integrated carriers, utility providers and original equipment manufacturers (“OEMs”) worldwide (all known as “service providers”). The power distribution and remote monitoring products are designed and provided through the Company’s Noran Tel subsidiary located in Regina, Saskatchewan, Canada.

OSP Products. The Company’s OSP products provide service providers with products to transport, maintain and improve the reliability of services delivered over copper and fiber lines in the local access network.

CNS and OSP Segment Research and Development Capabilities and Engineering Base

The Company believes that its future success depends, in part, on its ability to maintain its technological leadership through enhancements of its existing products and development of new products that meet customer needs. Thus, the Company expects to continue to devote substantial resources to product development.

In fiscal years 2011, 2010 and 2009, the CNS segment incurred approximately $7.9 million, $9.0 million and $15.0 million and the OSP segment incurred approximately $3.8 million, $2.3 million and $2.6 million, respectively, of expense for research and development (“R&D”) activities.

The Company’s R&D personnel are organized into product development teams. Each product development team is generally responsible for sustaining technical support of existing products plus conceiving new products in cooperation with other groups within the Company and adapting standard products or technologies to meet new customer needs. Additionally, in an effort to remain a highly valued, superior quality, long-term supplier, each product development team is charged with reducing product costs for each succeeding generation of products without compromising functionality or serviceability. The product development teams leverage the Company’s relationships with its manufacturing partners and suppliers to achieve these cost reduction objectives. As an adjunct to these internal efforts, the Company uses the talents of one outsourcing firm in India for software development and system testing in the CNS segment.

The Company believes that the key to its R&D strategy is choosing an initial architecture for each product that balances innovation and time-to-market factors while enabling engineering innovations to result in future performance enhancements and cost reductions. The Company’s strategy is further enhanced by ensuring products are designed in conjunction with input from customers, procurement, and outsource manufacturing partners. The Company believes it has a quality record that is grounded in a solid interface and transference of knowledge among design and manufacturing teams.

The Company’s quality systems, including product development processes, are registered to ISO9001:2008 International Quality System Standard and TL9000, which is the Telecommunication Industry’s sector-specific version of the ISO9001:2008. The Company believes product quality and reliability is a critical and distinguishing factor in a customer’s selection process.

Prior to the time of the sale of the majority of the CNS business, the Company continued to expand the software content of its CNS products. The majority of the CNS design engineers, including those at the contracted outsourcing firms, are software engineers. Greater software content in the CNS products not only is necessary to deliver the more sophisticated applications, but is also a key element of differentiated, value-added products and solutions. In some cases, the Company sources software technology from outside suppliers through licensing agreements which typically, though not always, give the Company the ability to modify the licensed software to meet the needs of the Company’s customers. Some software technology is obtained from the open source community. The Company also develops its own proprietary software where needed to provide the desired functionality. Software from all of these sources is typically integrated into the final product releases, and tested by the Company’s system test engineers, by outside test labs, by industry certification groups, and by the Company’s customers before going into volume production and deployment.

The Company expenses software development costs until its products reach technological feasibility as defined by the software accounting rules. Technological feasibility is established when the product has passed customer lab evaluation, which is just prior to deployment, therefore no software development costs are capitalized.

The following products are the primary products currently under development:

The Company’s products are subject to industry-wide standardization organizations which include Telcordia, the Internet Engineering Task Force, the MoCA Alliance, the Broadband Forum, CableLabs, the American National Standards Institute (“ANSI”) in the U.S. and the International Telecommunications Union (“ITU”).

CNS and OSP Segment Customers

The CNS and OSP segments’ principal customers historically have been major U. S. telecommunications service providers (“telephone companies”). In addition, the Company sells products to several other entities, including, independent domestic local exchange carriers, competitive local exchange carriers, inter-exchange carriers, wireless service providers, internet service providers, MSOs, integrators and distributors.

CNS and OSP Marketing, Sales and Distribution

The Company sells its products in the U.S. through its domestic field sales organization and selected distributors. The Company markets its products to service providers within the U.S. and Canada.

Major service providers require vendor product approval before use in their networks. Evaluation can take as little as a few months for products that vary slightly from existing products and often longer for products based on new technologies and/or new service offerings. Accordingly, the Company is continually submitting successive generations of its current products, as well as new products, to its customers for approval.

Table of Contents

The Company maintains telephone support and provides on-site support. The Company also provides technical consulting, research assistance and training to some of its customers with respect to the installation, operation and maintenance of its products.

The CNS and OSP contracts with its major customers are primarily pricing and product specification agreements that detail the commercial terms and conditions for sales. These agreements are requirements-based and typically do not obligate the customer to a specific volume of purchases over time. The agreements may require the Company to accept returns of products within certain time limits, or indemnify such customers against certain liabilities arising out of the use of the Company’s products. If these claims or returns are significant, there could be a material adverse effect on the Company’s business and results of operations.

Most of the Company’s products carry a limited warranty ranging from one to three years for CNS products and up to seven years for OSP products, which generally covers defects in materials or workmanship and failure to meet published specifications, but excludes damages caused by improper use. In the event there are material deficiencies or defects in the design or manufacture of the Company’s products, the affected products could be subject to recall.

Manufacturing

The Company outsources its manufacturing to two primary offshore suppliers. Reliance on third-party offshore subcontractors involves several risks. Standard commercial components available from multiple suppliers are procured by the offshore suppliers. In some cases, there are also single-sourced components and technology needed to produce products. The Company has direct relationships and purchase contracts with suppliers for these items and may maintain inventory for these items at the subcontractors’ locations. Critical components, technology shortages or business interruption at our contract manufacturers could cause production delays that may result in expediting costs or lost business.

A substantial portion of the Company’s shipments in any fiscal period can relate to orders for products received in that period. Further, a significant percentage of orders in the OSP segment may require delivery within 48 hours. To meet this demand, the Company maintains inventory at its facilities and outsource suppliers. In addition, the OSP segment maintains some inventory at customers’ sites. Because of the rapid technological changes to our products, the Company faces a recurring risk that the inventory it holds may become obsolete.

CNS and OSP Competition

The markets for the Company’s products are intensely competitive and the Company has no reason to believe that this competitive environment will ease in the future, especially in the rapidly changing markets for broadband products. The Company’s primary competitors vary by market. The Company’s principal competitors with respect to its OSP products include Charles Industries, Ciena, Emerson, Purcell, Ruggedcom, TE Connectivity and Telect. The Company’s principal competitors with respect to its CNS broadband products are primarily Sagem, Motorola, Pace (2Wire Inc.), Cisco Systems Inc. (Linksys), D-Link Systems Inc., Actiontec Electronics Inc., Technicolor and ZyXEL Communications Co. Prior to the sale of CNS assets and transfer of liabilities to NETGEAR in April 2011, the Company believed that it was one of the leading sellers of broadband customer premises equipment (“CPE”) products for telecommunication service providers in North America. However, many of the Company’s competitors are significantly larger, with broader product lines, and have more financial resources than the Company. To compete against these competitors, the Company focuses on quality, time-to-market, and the ability to react quickly to market changes, leveraging its U.S. based product management and product development teams. The Company expects that ongoing competitive pressure from Asian-based manufacturers will continue to exert downward pressure on pricing in the CNS segment.

Since the Company currently derives the majority of its total revenues from the sale of products to telephone companies, the Company faces indirect competition from alternative products optimized for other broadband networks. Telephone companies face competition from MSOs, new local access providers and broadband wireless service providers that are capable of providing high speed digital transmission to end users. OSP sells demarcation solutions including cabinets, enclosures, T1 network interface units without performance monitoring and T1 network protection devices to the cellular backhaul market. The Company believes that as the market transitions from T1 to Ethernet and as more alternative cellular backhaul solutions are deployed like DSL, HDSL, Ethernet, fiber and microwave the demand for the Company’s traditional OSP transmission T1 type products will decline. (Also, see Risk Factors in Item 1A of this report.)

Backlog

Product shipments are generally made pursuant to standard purchase orders, which are officially acknowledged according to standard terms and conditions. CNS segment purchase orders with scheduled shipment dates within 60 days are generally firm and non-cancellable. The majority of purchase orders with shipment dates in excess of 60-90 days allow for partial or full cancellation. Shipment dates on non-cancellable purchase orders may be adjusted by some customers on request. The CNS backlog as of May 13, 2011 disclosed below, however, is non-cancellable. OSP segment purchase orders are generally received less than a month prior to shipment.

As of May 13, 2011, the CNS and OSP segments had $18.5 million and $2.5 million of backlog, respectively. As of May 13, 2010, the CNS and OSP segments had $8.7 million and $4.0 million of backlog, respectively.

ConferencePlus Segment

Conference Plus, Inc. (“ConferencePlus” or “CP”), founded in 1988, is a full-service audio, web and video conferencing company that manages and hosts specific software and applications supporting its conferencing and meeting services. ConferencePlus is a 100% owned subsidiary of the Company and manages its conferencing and meeting services through its main operations center in Schaumburg, Illinois, and a facility in Dublin, Ireland.

ConferencePlus allows multiple individuals, organizations and/or businesses to conduct conference calls using a combination of audio, web and video collaboration and presentations. ConferencePlus offers conference call services that can include a blend of audio, graphics, spreadsheets and other documents that can be carried over and archived on the Internet to enhance the traditional audio conference call. By enabling the sharing of this blend of information, ConferencePlus can help organizations increase productivity and save money by reducing travel time and costs, and making it easier for people in remote locations to work together. Conferencing and meeting service technologies also allow organizations and individuals to collect and disseminate information faster, more accurately and without the associated costs of face-to-face meetings. These technologies also help companies communicate and collaborate effectively in the face of health and safety threats and other impediments to travel and formal gatherings.

ConferencePlus Customers - Diverse Distribution Channels

ConferencePlus has historically acted as a provider of conferencing and meeting services on a wholesale basis, managing and hosting applications for major carriers and telecommunications resellers. About 20% of ConferencePlus’ revenues come from indirect commercial conferencing services to customers who market or use ConferencePlus services under their own brand names. Such companies choose to outsource and private label audio, web and video conferencing services to maintain continuity, save costs and focus on their core competencies. By selling to indirect or resale customers, ConferencePlus effectively increases the size of its sales organization without incurring the expense necessary with a direct sales force.

ConferencePlus Sales

ConferencePlus also sells its services directly to companies through its national accounts sales force and a telesales team. This area continues to be a strong part of ConferencePlus’ business and the Company expects to continue to invest resources in this area in order to maintain a diverse mix of revenue sources. The deployment of this strategy is designed to improve the recognition of the ConferencePlus brand, which has strategic long term benefits to the Company.

ConferencePlus Research and Development - State-of-the-Art Network and Integrated Systems

The ConferencePlus segment incurred approximately $2.5 million, $2.2 million and $2.2 million, respectively, of research and development expense activities in fiscal years 2011, 2010 and 2009, respectively.

A critical part of ConferencePlus’ approach is its state-of-the-art network and integrated systems. ConferencePlus has a state-of-the-art network infrastructure that enables it to take advantage of the relationships it has with major telecommunications providers to provide quality service. ConferencePlus has deployed equipment in carrier Points-of-Presence to take advantage of the higher capacity and the lower cost structure available with such deployments.

Table of Contents

The Company has also deployed equipment into customer datacenters to leverage existing investments in next-generation VoIP corporate networks. These deployments provide all of the advantages ConferencePlus provides through traditional service provider solutions while allowing these Customers to benefit from the elimination of variable telecommunication costs.

ConferencePlus has built an integrated reservation, scheduling and billing system called Conference Reservation and Billing System (“CRBS”) that is a significant differentiator in the conferencing market. CRBS allows ConferencePlus to leverage its operations on a global basis. This reliable and scalable system is seamlessly integrated into the operational environment from the point of reservation through the billing process. This integration allows ConferencePlus to enjoy scale advantages and to be able to provide transparent branded services to its customers. This system is built and maintained by an in-house team of engineers, developers and technicians who continually work to improve and enhance the system based on industry trends, customer requests and strategic direction.

ConferencePlus has extended certain capabilities of CRBS to a publicly available web portal where customers can sign up for service, manage their accounts and control their conferences. ConferencePlus has also tightly integrated with third-party suppliers of web conferencing services to enhance its audio services. In addition to making these services available to customers, ConferencePlus has the ability to privately brand the entire web experience to match any other brand visualization that may be required. This capability is beneficial for both indirect customers where this helps support the indirect brand as well as for customers where branding can help drive corporate adoption.

ConferencePlus International Reach

As customers globalize their telecommunications services, ConferencePlus has expanded its operational presence internationally to meet these needs. In addition to its main operational centers in Schaumburg, Illinois and Dublin, Ireland, ConferencePlus has conferencing bridges located in Chicago, Illinois; Oakbrook, Illinois; New York, New York; Dallas, Texas; London, England; Stockholm, Sweden and Kuala Lumpur, Malaysia. The international market for conferencing is expected to grow as a result of deregulation and improved networks with associated reductions in end user costs.

ConferencePlus Customers

ConferencePlus’ indirect or private label customers and many of its other customers are significantly larger than, and are thus able to exert a high degree of influence over, ConferencePlus. ConferencePlus depends on large customers to provide a significant percent of its revenues. Although the Company has focused on broadening its customer base, a loss of one of these large customers could have a material adverse effect on ConferencePlus’ business. Prior to selling its services, ConferencePlus may be required to undergo lengthy approval and purchase processes. Evaluation can take a few months for services that vary slightly from existing services used by the prospective customer to a year or more for services based on cutting edge technologies or which represent a new strategic direction for the customer, as is the case with private labeling conference services for a large reseller.

ConferencePlus Competition

Competition in the conferencing business is intense and ConferencePlus expects that competition will increase due to low barriers to entry and recent entrants into the audio, web and video conferencing service market. Many of ConferencePlus’ competitors, including InterCall, AT&T, Verizon, Premiere and British Telecom, have greater name recognition, more extensive customer service and marketing capabilities and substantially greater financial, technological and personnel resources than ConferencePlus. There can be no assurance that ConferencePlus will be able to successfully compete in this market in the future or that competitive pressures will not result in price reductions that would materially adversely affect its business and results of operations.

Consolidated International Revenue

Revenues from international customers represented approximately $9.8 million, $11.1 million and $9.1 million of the Company’s revenues in fiscal years 2011, 2010, and 2009, respectively, which represents approximately 5.1%, 6.1% and 4.9% of the Company’s total revenues in such years.

Major Customers

The Company depends, and may continue to depend, on the telephone companies and other independent local exchange carriers for the majority of its revenues. Sales to the Company’s largest customer, Verizon, accounted for 30.6% of the Company’s total revenues in fiscal year 2011.

Proprietary Rights and Intellectual Property

The Company’s success and future revenue growth will depend, in part, on its ability to protect trade secrets, obtain or license patents and operate without infringing on the rights of others. The Company relies on a combination of technical leadership, copyrights, patents, trademarks, trade secrets and other intellectual property laws, nondisclosure agreements and other protective measures to protect its unpatented proprietary know-how. The Company regards some of its technology as proprietary. The expiration of any of the patents held by the Company would not have a material impact on the Company. The Company expects to seek additional patents from time to time related to its research and development activities.

Employees

As of May 13, 2011, the Company had 365 full-time employees. The following table reflects headcount by segment and functional area:

You should carefully consider the risks described below in addition to the other information contained and incorporated by reference in this Form 10-K. If any of the following risks occurs, our business, operating results or financial condition would likely suffer, and the market price for our securities could decline.

Risks Related to Our Business

General economic conditions may affect our results.

The global economy has been undergoing a period of unprecedented volatility, which has affected the demand for our equipment and services. A prolonged period of economic decline could have a material adverse effect on our results of operations and financial condition. The Company may experience a decrease in purchases or usage of our products and services if increased unemployment leads to lower utilization of telecommunications and conferencing services. Customers may stop or decrease purchasing due to efforts to reduce inventory and conserve cash. The Company may also experience business disruptions due to an inability to obtain equipment, parts and supplies from suppliers if fragile supply businesses fail.

We depend on a limited number of customers who are able to exert a high degree of influence over us and loss of a major customer could adversely impact our business.

We have and may continue to depend on U.S. telephone companies for the majority of our revenues in our CNS and OSP equipment segments. The telephone companies and our other customers are significantly larger than we are and are able to exert a high degree of influence over us. These customers may often be permitted to reschedule orders without penalty. Even if demand for our products is high, the telephone companies have sufficient bargaining power to demand low prices and other terms and conditions that may materially adversely affect our business and operating results.

ConferencePlus’ customer base is relatively concentrated; its top twenty-five customers represent a large portion of total revenue and income. ConferencePlus’ customers continually undergo review and evaluation of their conferencing and meeting services to evaluate the merits of alternative outsourcing or of bringing those services in-house rather than outsourcing them. There can be no assurance in the future that ConferencePlus’ customers will not develop their own internal conferencing and meeting services. ConferencePlus must continually provide higher quality, lower cost services to maintain and grow its customer base. A loss of a major account could have a material adverse effect on ConferencePlus.

Overall sales and product mix sold to our large customers have fluctuated in the past and could vary in the future resulting in significant fluctuations in quarterly operating results which may adversely impact our stock price.

We have long-term customer pricing contracts with a limited amount of coverage by way of long-term contracts or arrangements with suppliers, which could adversely affect our ability, with certainty or economically, to purchase components and technologies used in our products.

Although we have long-term customer pricing contracts, we have few long-term contracts or arrangements with our suppliers. We may not be able to obtain components at competitive prices, in sufficient quantities or under other commercially reasonable terms. If we enter into a high-volume or long-term supply arrangement and subsequently decide that we cannot use the products or services provided for in the supply arrangement then our business would also be harmed. We enter into short-term contracts with our suppliers in the form of purchase orders. Purchase orders are often non-cancellable within contractual time periods. These purchase orders are issued to vendors based on forecasted customer demand. If the forecasted demand is materially incorrect, we may find that we cannot use the products ordered, and then our business would also be harmed.

Our lack of backlog may affect our ability to adjust for unexpected changes in customer demand.

OSP customers often place orders for product within the month of their requested delivery date. We therefore do not have a material backlog (or known quantity) of unfilled orders, and our revenues in any quarter are substantially dependent on orders booked or orders becoming non-cancellable in that quarter. Our expense levels and inventory

- 10 -

Table of Contents

commitments are based on anticipated customer demand and are relatively fixed in the short term. Therefore, we may be unable to cancel purchase orders with our suppliers or adjust spending in a timely manner to compensate for any unexpected shortfall of orders. Accordingly, any significant shortfall of demand in relation to our expectations or any material delay of customer orders would have an immediate adverse impact on our business and operating results.

Conversely, if we order too little product to meet customer demand, we may have insufficient inventory which could result in unplanned expediting costs or lost revenue opportunities, either of which could have an adverse impact on our financial results.

We may experience delays in the development and deployment of new products.

Many of our past sales have resulted from our ability to anticipate changes in technology, industry standards and service provider service offerings, and to develop and introduce new and enhanced products and services. Our continued ability to adapt to such changes will be a significant factor in maintaining or improving our competitive position and our prospects for growth.

There can be no assurance that we will successfully introduce new products on a timely basis or achieve sales of new products in the future. In addition, there can be no assurance that we will have the financial and product design resources necessary to continue to successfully develop new products or to otherwise successfully respond to changing technology standards and service provider service offerings. If we fail to deploy new products on a timely basis, then our product sales will decrease and our competitive position and financial condition would be materially and adversely affected.

Our customers have lengthy purchase cycles that affect our ability to sell our products.

Prior to selling products to service providers, we must undergo lengthy approval and purchase processes. Evaluation can take as little as a few months for products that vary slightly from existing products or up to a year or more for products based on new technologies or utilized for new service offerings. Accordingly, we are continually submitting successive generations of our current products as well as new products to our customers for approval.

The requirement that service providers obtain FCC or state regulatory approval for most new telecommunications and broadband services prior to their implementation has in the past delayed the approval process. Such delays in the future could have a material adverse affect on our business and operating results. While we have been successful in the past in obtaining product approvals from our customers, there is no guarantee that such approvals or that ensuing sales of such products will continue to occur.

We are dependent on our independent offshore outsource manufacturing partners to manufacture, assemble and test our products. If these companies do not meet their commitments to us, it could adversely impact our ability to meet the delivery requirements of our customers, which could result in lost business.

We are dependent on offshore suppliers in Asia. Although there is no unique capability with these suppliers, any failure or business disruption by these suppliers to meet delivery commitments would cause us to delay shipments and potentially lose revenue.

We rely on subcontractors in Asia for assembly and testing of and to purchase raw materials used in such assemblies. The reliance on third-party subcontractors for assembly of our products involves several risks, including the unavailability of, or interruptions in access to, certain process technologies and reduced control over product quality, delivery schedules, transportation, manufacturing yields, and costs. These risks may be exacerbated by economic or political uncertainties, terrorist actions, or by natural pandemics or other disasters in countries in which our subcontractors or their subcontractors are located. Contracts with our outsource manufacturing partners are expressed in U.S. dollars, but volatility in foreign currency rates could increase our costs.

ConferencePlus maintains call centers and bridging equipment in the United States, Ireland, England, Sweden and Malaysia. If any of the call centers or bridging equipment were unavailable due to natural or other disaster, then our business could be harmed.

Because ConferencePlus conducts a substantial amount of business via the internet, its systems can be the target of cyber-attacks or hacking for the purpose of gaining access to information or fraudulently using the services. Such attacks, if not properly detected and defended against, can result in business interruption and other harm to the business.

Due to the rapid pace of technological change and volatile customer demand, our products may become obsolete and could cause us to incur charges for excess and obsolete inventory which would materially harm our business.

The telecommunications industry is subject to rapid technological change and volatile customer demands, which could result in inventory obsolescence or excess inventory. As a result, we have in the past and may in the future devote disproportionate resources to a product that we ultimately may not sell or have to sell for a loss. If we incur substantial inventory impairments that we are not able to recover because of changing market conditions, it could have a material adverse effect on our business, financial condition and results of operations.

Our products and services face intense competition. Our failure to compete successfully could materially affect our profitability.

Because we are significantly smaller than many of our competitors, we may lack the financial, marketing, technical and other resources needed to increase our market share. Many of our competitors are much larger than we are and may be able to offer a wider array of products and services required for a service provider’s business than we do.

Competitors may succeed in establishing technologically advanced products and services with more favorable pricing or may otherwise gain an advantage over our products which would result in lost business that would adversely impact our profitability.

Because of intense competition, we may price our products and services at low margins in order to win or maintain business. Low margins from our sales of products and services could materially and adversely affect our profitability and ability to implement our business goals.

We are dependent on third-party technology, the loss of which would harm our business.

We rely on third parties for technology in our products and to deliver our services. Consequently, the Company must rely upon third parties to develop and to introduce technologies which enhance the Company’s current products and services and enable the Company, in turn, to develop its own products and provide services on a timely and cost-effective basis to meet changing customer needs and technological trends in the telecommunications industry. Were the Company to lose the ability to obtain needed technology from a supplier, or were that technology no longer available to the Company under reasonable terms and conditions, the Company’s business and results of operations would be materially and adversely affected.

Potential product recalls, service failures and warranty expenses could adversely affect our profitability.

Our products and services are required to meet rigorous standards imposed by our customers, and we warrant the performance of these products and services. In addition, our supply contracts with our major customers typically require us to accept returns of products within certain time frames and indemnify such customers against certain liabilities arising out of the use of our products or services. Complex products such as those offered by us may contain undetected defects or failures when first introduced or as new versions are released. Despite our testing of products and our comprehensive quality control program, there is no guarantee that our products will not suffer from defects or other deficiencies. If product defects, recalls, warranty returns, service failures, indemnification or liquidated-damage claims exceed our anticipated costs for these items, our business could be harmed. Such claims and the associated negative publicity could result in the loss of or delay in market acceptance of our products and services, and could affect our product and service sales, our customer relationships, and our profitability.

We are dependent on sole or limited source suppliers, the loss of which would harm our business.

Components used in our products may be currently available from only one source or a limited number of suppliers. Our inabilities to obtain sufficient key components or to develop alternative sources for key components as required, could result in delays or reductions in product deliveries, and consequently severely harm our customer relationships and our business. Furthermore, additional sole-source components may be incorporated into our future products, thereby increasing our supplier risks. If any of our sole-source suppliers delay or halt production of any of their components, or fail to supply their components on commercially reasonable terms, then our business and operating results would be harmed.

In the event that these suppliers discontinue the manufacture of materials used in our products, we would be forced to incur the time and expense of finding a new supplier if available or to modify our products in such a way that such materials were not necessary, which could result in increased manufacturing costs.

We may be subject to litigation that could be costly to defend and could impact our profitability.

Our products and services use third party and open source intellectual property. The telecommunications industry is characterized by the existence of an increasing number of patents and frequent litigation based on allegations of patent and other intellectual property infringement. From time to time we receive communications from third parties alleging infringement of exclusive patent, copyright and other intellectual property rights to technologies that are important to us. Such litigation, regardless of its outcome, could result in substantial costs and thus adversely impact our profitability.

We could face securities litigation in the future that could result in the payment of substantial damages or settlement costs in excess of our insurance coverage. Any adverse outcome could harm our business. Even if we were to prevail in any such litigation, we could incur substantial legal costs and management’s attention and resources could be diverted from our business which could cause our business to suffer.

We will not be able to successfully compete, develop and sell products and services if we fail to retain key personnel and hire additional key personnel.

Because of our need to continually compete for customer business, our success is dependent on our ability to attract and retain qualified technical, marketing, sales and management personnel. To remain competitive, we must maintain top management talent, employees who are involved in product development and testing and employees who have developed strong customer relationships. Because of the high demand for these types of employees, it may be difficult to retain existing key employees and attract new key employees. In addition, we do not have non-compete contracts with most of our employees. Our inability to attract and retain additional key employees could harm our ability to successfully sell existing products and services, develop new products and services, and implement our business goals.

Industry consolidation and divestiture and could make competing more difficult.

Consolidation of companies offering competing products and services is occurring through acquisitions, joint ventures and licensing arrangements involving our competitors, our customers and our customers’ competitors.

Our customers have been divesting certain territories to other telecommunication service providers. The acquiring companies often use competitor products in their legacy business. We are often required to formally bid to retain existing business or obtain new business in the acquirer’s territory.

We cannot provide any assurances that we will be able to compete successfully in an increasingly consolidated telecommunications industry or retain or win business when existing customers divest portions of their business to others. Any heightened competitive pressures that we may face may have a material adverse effect on our business, prospects, financial condition and result of operations.

We may engage in future acquisitions or fund raising activity that could impact our financial results or stock price.

We expect to continue to review potential acquisitions and we may acquire or make investments in businesses, products or technologies in the future. Any substantial future acquisitions or investments would present a number of risks that could harm our business including:

We expect consideration for potential acquisitions or investments to be paid in cash, common stock or a combination of both. If consideration is paid in common stock, this would dilute the ownership of our existing stockholders.

Availability of our deferred tax assets could be limited by an ownership change as defined by Section 382 of the Internal Revenue Code, or by a change in the tax code.

We have significant deferred tax assets, primarily in the form of net operating losses, which are generally available to offset future taxable income. A change in ownership, as defined by Section 382 of the Internal Revenue Code, could reduce the availability of those tax assets. In addition, some tax jurisdictions such as Illinois and Florida have suspended the use of net operating losses to offset future taxable income for a period of time. Additional federal or state tax code changes could further limit our use of deferred tax assets and harm our business and our investors.

We have agreed to indemnify NETGEAR against specified losses in connection with the sale of certain assets of the CNS business.

Under the terms of the Asset Purchase Agreement dated as of March 17, 2011, we have agreed to indemnify NETGEAR following the closing of the sale of certain assets of the CNS business against specified losses in connection with the CNS business and generally retain responsibility for various legal liabilities that may accrue. We have also made representations and warranties to NETGEAR about the condition of CNS, including matters relating to intellectual property, employee matters and environmental laws. Following the closing, if NETGEAR makes an indemnification claim because it has suffered a loss or a third party has commenced an action against NETGEAR, we may incur expenses to resolve NETGEAR’s claim or to defend NETGEAR and ourselves against the third party action, which expense could harm our operating results. In addition, such indemnity claims may divert management attention from our continuing business. It may also be difficult to determine whether a claim from a third party stemmed from actions taken by us or by NETGEAR and we may expend substantial resources trying to determine which party has responsibility for the claim.

Our services are affected by uncertain government regulation and changes in current or future laws or regulations could restrict the way we operate our business.

The telecommunications industry, including most of our customers, is subject to regulation from federal and state agencies, including the FCC and various state public utility and service commissions. While most such regulations do not affect us directly, the effects of regulations on our customers may adversely impact our business and operating results. For example, FCC regulatory policies affecting the availability of telephone company services and other terms on which telephone companies conduct their business may impede our penetration of local access markets, and/or make the markets less financially attractive.

Risks Related to our Common Stock

We have been and could be the subject of future investigation by the SEC or other governmental authorities that could adversely affect our financial condition, results of operations and the price of our common stock.

In the past, the SEC conducted an investigation regarding events and circumstances surrounding trading in our securities. In August 2009, the SEC informed us that it had completed this investigation without any enforcement action. In the event that a future investigation by the SEC or other governmental authorities leads to significant legal expense or to action against the Company or its directors and officers our financial condition, results of operations and the price of our common stock may be adversely impacted.

Our principal stockholders can exercise significant influence that could discourage transactions involving a change of control and may affect your ability to receive a premium for Class A Common Stock that you purchase.

As of May 13, 2011, as trustees of a voting trust, dated February 23, 1994 (the “Voting Trust”), containing common stock held for the benefit of the Penny family, Robert C. Penny III and Robert W. Foskett have the exclusive power to vote over 48.0% of the votes entitled to be cast by the holders of our common stock. In addition, members of the Penny family who are beneficiaries under this Voting Trust are parties to a stock transfer restriction agreement which prohibits the beneficiaries from transferring any Class B Common Stock or their beneficial interests in the Voting Trust without first offering such Class B Common Stock to the other Penny family members. Certain Penny family members also own or are beneficiaries of trusts that own shares outside of the Voting Trust. As trustees of the Voting Trust and other trusts, Messrs. Penny and Foskett control 51.6% of the stock vote. Consequently, we are effectively under the control of Messrs. Penny and Foskett, as trustees, who can effectively control the election of all of the directors and determine the outcome of most corporate transactions or other matters submitted to the stockholders for approval. Such control may have the effect of discouraging transactions involving an actual or potential change of control, including transactions in which the holders of Class A Common Stock might otherwise receive a premium for their shares over the then-current market price. On May 31, 2011, the Company purchased 1,000,000 shares from the Penny family (see note 15 Subsequent Events).

None.

The Company leases the following real property:

The Aurora facility is used for its corporate headquarters , product distribution, and warranty processing. Alternative uses are currently being explored for portions of the Aurora facility that exceed the Company’s requirements. In April 2011, the Company entered into an agreement with NETGEAR to sublease a portion of the Aurora facility for a minimum period of six months. The Company has reached a preliminary agreement, subject to negotiation of specific lease terms, to extend the lease of the Regina facility.

The Company does not own any real property.

The Company is involved in various legal proceedings incidental to the Company’s business. In the ordinary course of our business, we are routinely audited and subject to inquiries by governmental and regulatory agencies. Management believes that the outcome of such proceedings will not have a material adverse effect on our consolidated operations or financial condition.

Overview

The following discussion should be read together with the Consolidated Financial Statements and the related Notes thereto and other financial information appearing elsewhere in this Form 10-K. All references herein to the term “fiscal year” shall mean a year ended March 31 of the year specified.

The Company commenced operations in 1980 as a provider of telecommunications network transmission products that enable advanced telecommunications services over copper telephone wires. Until fiscal 1994, the Company derived substantially all of its revenues from its Outside Plant Systems (“OSPlant Systems” or “OSP”) products, particularly the sale of Network Interface Unit (“NIU”) products and related products. The Company introduced its first Customer Networking Solutions (“CNS”) products in fiscal 1993. The Company has also provided audio teleconferencing services since fiscal 1989 through its Conference Plus, Inc. subsidiary. The Company realizes the majority of its revenues from the North American market.

On March 17, 2011, the Company entered into a definitive agreement to sell certain assets and transfer certain liabilities of the CNS segment to NETGEAR, Inc. (“NETGEAR”) for $33.5 million in cash, subject to certain adjustments. This transaction closed on April 15, 2011. As part of the asset sale, most of the CNS segment’s customer relationships, contracts and employees were transferred to NETGEAR. The Company retained one major CNS customer relationship and contract, and also retained the Homecloud product development program.

Prior to the CNS asset sale to NETGEAR, the CNS segment of the Company designed, distributed, marketed and serviced a broad range of carrier-class broadband products. The CNS family of broadband products enables high-speed transport and networking of voice, data, video, and other advanced services. The products allow service providers to deliver services, content, and applications over existing copper, fiber, coax, and wireless infrastructures. Westell CNS products are typically installed in consumer residences or small businesses as a key component of a broadband service package. The Company’s CNS products enable residential customers, small businesses, and small office/home office (“SOHO”) users to access and share broadband services on networked computers, telephones, cell phones, televisions, media players, and other networked devices. A broad offering of networking products and technologies allows the Company to address several segments of the service provider market, distinguished by the methods used to deliver their services: wireline operators (copper and fiber), cable multi-service operators (hybrid fiber-coax), and integrated carriers that operate as combinations of the other three operators.

After the CNS asset sale to NETGEAR, the Company retains one major CNS customer relationship and contract, and expects to sell and service traditional CNS products to that customer through the end of the contract. As of May 13, 2011, the Company had $18.5 million of non-cancellable orders from this customer and expects to complete shipment of product under this contract by December 31, 2011. The Company also retained within its CNS division the Homecloud product development program. The Homecloud product family which is under development consists of ultra-high-speed applications-capable gateways and other applications-capable devices for the home network, plus associated software for home networking devices, plus Web-based services, to enable the delivery of new services into the home networking environment.

In the OSP segment, the Company designs, distributes, markets and services a broad range of carrier-class digital transmission, remote monitoring, power distribution, next-generation outdoor equipment cabinets and service provider demarcation products. The Company’s OSP products offer next-generation outdoor cabinets, enclosures, power distribution panels, flexible edge connectors (with respect to fiber, Ethernet and coax), remote monitoring solutions, DS1 and DS3 transmission plugs, and carrier grade Ethernet solutions. These solutions are optimized for wireline backhaul of cellular traffic, service delivery to business enterprise and smart grid applications. The Company’s OSP segment also provides a value-added Customized Systems Integration (“CSI”) service, offering its customers a single source for complete turnkey solutions, reducing the time-to-market and expenses incurred through third-party contractors and eliminating the need to design, assemble and test on the job site. Target OSP customers include wireline service providers, wireless service providers, multiple systems operators (“MSOs”), integrated carriers, utility providers and original equipment manufacturers (“OEMs”) worldwide (all known as “service providers”). The power distribution and remote monitoring products are designed and provided through the Company’s Noran Tel subsidiary located in Regina, Saskatchewan, Canada.

Conference Plus, Inc. (“ConferencePlus” or “CP”), founded in 1988, is a full-service audio, web and video conferencing company that manages and hosts specific software and applications supporting its conferencing and meeting services. ConferencePlus is a 100% owned subsidiary of the Company and manages its conferencing and meeting services through its main operations center in Schaumburg, Illinois, and a facility in Dublin, Ireland.

ConferencePlus allows multiple individuals, organizations and/or businesses to conduct conference calls using a combination of audio, web and video collaboration and presentations. ConferencePlus offers conference call services that can include a blend of audio, graphics, spreadsheets and other documents that can be carried over and archived on the Internet to enhance the traditional audio conference call. By enabling the sharing of this blend of information, ConferencePlus can help organizations increase productivity and save money by reducing travel time and costs, and making it easier for people in remote locations to work together. Conferencing and meeting service technologies also allow organizations and individuals to collect and disseminate information faster, more accurately and without the associated costs of face-to-face meetings. These technologies also help companies communicate and collaborate effectively in the face of health and safety threats and other impediments to travel and formal gatherings.

The prices for the products within each market group vary based upon volume, customer specifications and other criteria, and are subject to change due to competition among telecommunications manufacturers and service providers.

The Company’s customer base for its products is highly concentrated and comprised primarily of major U.S. telecommunications service providers (“telephone companies”), independent domestic local exchange carriers and public telephone administrations located outside the U.S. Due to the stringent quality specifications of its customers and the regulated environment in which its customers operate, the Company must undergo lengthy approval and procurement processes prior to selling its products. Accordingly, the Company must make significant up front investments in product and market development prior to actual commencement of sales of new products.

To remain competitive, the Company must continue to invest in new product development and invest in targeted sales and marketing efforts to launch new product lines. Failure to increase revenues from new products, whether due to lack of market acceptance, competition, technological change or otherwise, could have a material adverse effect on the Company’s business and results of operations. The Company expects to continue to evaluate new product opportunities and engage in extensive research and development activities.

In view of the Company’s current reliance on the telecommunications market for revenues and the unpredictability of orders and pricing pressures, the Company believes that period-to-period comparisons of its financial results are not necessarily meaningful and should not be relied upon as an indication of future performance.

After the CNS asset sale to NETGEAR, in the CNS segment, the Company is focusing on the Homecloud product development program as well as fulfilling its contractual obligations in the retained CNS customer relationship and contract. The under development Homecloud product family provides a new suite of services, beyond voice + video + data, into the home, for a variety of applications, including enhanced security; media and information management, sharing and delivery; home control; and network management. The Company is considering sale of Homecloud products to its traditional service provider customer base as well as through new partnerships with online cloud-based service providers, and to consumers via various retail and online retail channel partners.

The OSP segment has introduced products and services that focus on customer diversification and has changed from being a provider centered on service to Regional Bell Operating Companies into a provider with new sales channels including independent operating companies (“IOCs”), wireless service providers, MSOs, utility providers and OEMs worldwide. The Company continues to invest in new product areas to compliment the cellular backhaul and smart grid applications.

Critical Accounting Policies

The Company uses estimates and judgments in applying its accounting policies that have a significant impact on the results reported in the Consolidated Financial Statements. The following are the Company’s most critical accounting policies.

- 20 -

Table of Contents

Inventory Reserves

The Company reviews inventory for excess quantities and obsolescence based on its best estimates of future demand, product lifecycle status and product development plans. The Company uses historical information along with these future estimates to reserve for obsolete and potentially obsolete inventory. The Company also evaluates inventory to adjust valuations to be the lower of cost or market value. Prices anticipated for future inventory demand are compared to current and committed inventory values.

Inventory Purchase Commitments

In the normal course of business, the Company enters into non-cancellable commitments for the purchase of inventory and long-distance telephone services. The commitments are at market rates. Should there be a significant decline in revenues the Company may absorb excess inventory and subsequent losses as a result of these commitments. The Company establishes reserves for potential losses on at-risk commitments.

Income Taxes

Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the tax differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

Goodwill and Intangibles

Pursuant to the requirements of Accounting Standards Codification (“ASC”) topic 350, Intangibles-Goodwill and Other (“ASC 350”), the Company evaluates its goodwill for impairment on an annual basis during the fourth quarter of each fiscal year or at an interim period if indicators of impairment exist. The goodwill impairment test compares the fair value of a reporting unit with its carrying value. If the carrying value of a reporting unit exceeds its fair value, goodwill of the reporting unit would be considered impaired. To measure the amount of the impairment loss, the fair value of a reporting unit’s goodwill is compared to the carrying value of that goodwill. If the carrying value of a reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner used to determine the amount of goodwill recognized in a business combination. The fair value of each of the Company’s reporting units was determined using a discounted cash flow methodology and current like-company market transactions. In fiscal year 2009, impairment of $1.4 million was recorded at the Noran Tel reporting unit in the OSP segment. No impairment was recorded in fiscal years 2011 or 2010.

On an ongoing basis, the Company reviews intangible assets and other long-lived assets other than goodwill for impairment whenever events and circumstances indicate that carrying values may not be recoverable. If such events or changes in circumstances occur, the Company will recognize an impairment loss if the fair value is less than the carrying value of the related asset. The impairment loss would adjust the asset to its fair value.

Revenue Recognition and Deferred Revenue

Revenue recognition on equipment where software is incidental to the product as a whole or where software is essential to the equipment’s functionality and falls under software accounting scope exceptions generally occurs when products are shipped, risk of loss has transferred to the customer, objective evidence exists that customer acceptance provisions have been met, no significant obligations remain, collection is reasonably assured and warranty can be estimated.

Where multiple-element arrangements exist, fair value of each element is established using the relative selling price method, which requires the Company to use vendor-specific objective evidence (“VSOE”), reliable third-party objective evidence (“TPE”) or management’s best estimate of selling price, in that order.

The Company’s UltraLine Series3 products are sold primarily to a single customer with contractual provisions that include specified future software enhancements and post customer support (“PCS”) to maintain ongoing interoperability within the customer’s network. The Company was not able to establish VSOE or TPE for the specified future software enhancements and therefore relied on management’s estimates of fair value for each of the multiple elements in the arrangement. Revenue is deferred for undelivered elements and recorded when delivery occurs.

- 21 -

Table of Contents

Stock–based Compensation

The Company accounts for stock-based compensation using the provisions of ASC topic 718, Compensation – Stock Compensation (“ASC 718”). ASC 718 requires the grant date fair value recognition of expense related to employee stock-based compensations awards over the requisite service period. Determining the fair value of equity-based options requires the Company to estimate the expected volatility of its stock, the risk-free interest rate, expected option term, expected dividend yield and expected forfeitures.

Warranty Costs

Most of the Company’s products carry a limited warranty ranging from one to three years for CNS segment products and up to seven years for OSP segment products. The warranty reserve is based on historical sales and cost of repair or replacement trends.

New Accounting Standards Adopted

In February 2010, the FASB issued Accounting Standards Update (“ASU”) 2010-10, Consolidations (Topic 810): Amendments for Certain Investment Funds and in December 2009, the FASB issued ASU 2009-17, Consolidations (Topic 810): Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities. These ASU’s amend the variable interest entity (“VIE”) guidance of ASC 810 (see effective date below).

Effective April 1, 2010, the Company adopted the new VIE guidance of ASC 810. This guidance amends ASC 810, to require the Company to perform an analysis of existing investments to determine whether variable interest or interests give the Company a controlling financial interest in a VIE. This analysis identifies the primary beneficiary of a VIE as the enterprise that has both the power to direct the activities of significant impact on a VIE and the obligation to absorb losses or receive benefits from the VIE that could potentially be significant to the VIE. It also amends ASC 810 to require ongoing reassessments of whether an enterprise is the primary beneficiary of a VIE. As a result of adoption, the Company is no longer considered the primary beneficiary of Contineo, a VIE for which the Company was considered the primary beneficiary and which required the financial performance of Contineo to be consolidated in the Company’s financial statements in fiscal years 2010 and 2009. Because the Company is no longer considered the primary beneficiary, the Company is not required to consolidate Contineo in its financial statements effective April 1, 2010. As a result of the adoption of the new VIE guidance in ASC 810, the Company recorded a cumulative-effect adjustment to increase retained earnings by $0.3 million. This adjustment represents the difference between the cumulative net losses of $2.8 million previously recorded through the consolidation of Contineo and the Company’s $2.5 million investment. The Company’s equity value of the Contineo investment recorded on the Company’s books as of March 31, 2011 is $0.

Results of Operations

Fiscal Years Ended March 31, 2011, 2010 and 2009

- 22 -

Table of Contents

In fiscal year 2011, consolidated revenue increased 5% compared to the prior year. CNS segment revenue increased 2%. Gateway product revenue increased 61% and modem product revenue decreased 44%. In the current year, end user demand continued to shift from modems toward wireless gateways. The ULS3 product revenue decreased 31%. Average selling prices between years decreased in all three products. OSP revenue increased 12% due primarily to strong demand for products used in cellular backhaul initiatives offset by overall weaker demand for network interface and mounting products. ConferencePlus revenue was relatively flat with an increase of 1% on higher minutes billed, offset in part by a lower rate per minute billed.

In fiscal year 2010, consolidated revenue decreased 2% compared to the prior year. CNS segment revenue increased 4% with unit volume increases offset in part by a decrease in average sales price for both modem and gateway products. The ULS3 product revenue units decreased 6% with stable average selling prices between years. The 7% decrease in OSP revenue resulted from an overall weaker demand for network interface and mounting products. The 8% ConferencePlus revenue decrease was due to the weak economic environment and a loss of revenue from large customers offset in part by the addition of smaller customers which combined for a decrease in call minutes. The decrease was offset in part by $1.2 million of additional revenue related to the collection of the Federal Universal Service Fund (“FUSF”) fees.

In fiscal year 2011, consolidated margin increased 1.0% compared to fiscal year 2010. CNS gross margin increased 1.4%. The CNS gross margin was negatively impacted by lower selling prices but benefited from a more profitable product mix, including $0.9 million of revenue from higher-margin software revenue related to customer projects, when compared to the prior year. OSP and ConferencePlus gross margins were relatively flat year over year.

In fiscal year 2010, consolidated gross margin increased 4.3% compared to fiscal year 2009. CNS gross margin increased 6.7% due primarily to a favorable mix of products sold and lower material costs that resulted from cost-reduced modem and gateway products along with lower freight costs of $1.1 million. Expedited freight was incurred in fiscal year 2009 relating primarily to the ULS3 product and did not recur in fiscal year 2010. OSP gross margin increased 3.5% due to product mix and freight costs that were lower by $0.4 million. ConferencePlus gross margin was negatively impacted in fiscal year 2009 by a loss contingency reserve of $0.7 million for a contractual dispute. The ConferencePlus margin improvement to 48.7% in fiscal year 2010 resulted primarily from lower telecommunication costs caused by a change in the provider of those services and the absence of a $0.7 million loss contingency reserve that was incurred in fiscal year 2009.

In fiscal year 2011, consolidated sales and marketing expense increased 1% or $0.2 million compared to the prior year. Certain sales and marketing resources that supported the CNS segment in fiscal year 2010 were transferred to support the OSP segment in fiscal year 2011. This transfer resulted in lower CNS and higher OSP sales and

marketing expenses in the current year compared to the prior year. CNS sales and marketing expense declined $0.9 million. In addition to the resource transfer noted above, lower warranty and shipping expenses also impacted fiscal year 2011, but were offset by increased spending on the Homecloud initiative, which started in the second quarter of fiscal year 2011. OSP sales and marketing expenses increased 19% or $0.9 million due primarily to the resource changes noted above. In addition, compensation costs increased due to higher commission expense resulting from increased year-over-year OSP revenue. ConferencePlus sales and marketing expenses increased 3% or $0.2 million due to the addition of sales employees in the current year compared to the prior year.

In fiscal year 2010, consolidated sales and marketing expense decreased 26% or $6.2 million compared to the prior year with reductions in all operating segments due primarily to reorganizations which resulted in fewer employees and lower related personnel costs. In the CNS and ConferencePlus segments, there were 15 and 16 fewer employees as of March 31, 2010 compared to March 31, 2009, respectively. The Company also placed cost controls in each division which resulted in lower spending across most expense categories.

In fiscal year 2011, consolidated research and development expenses increased 5% or $0.7 million compared to the prior year. In fiscal year 2011, certain engineering employees that supported the CNS segment in the prior fiscal year were transferred to support development of Ethernet solutions for the OSP segment in the current fiscal year. This personnel transfer had the effect of creating lower CNS and higher OSP research and development expense. CNS research and development expenses decreased 12% or $1.1 million. The reduction was primarily due to lower salary and related costs due to the personnel changes noted above, and a general reduction in overall expenses, including depreciation. This was offset in part by increased spending on the Homecloud initiative, which has been increasing throughout fiscal year 2011. OSP research and development expenses increased 64% or $1.5 million. The increase resulted from the personnel changes noted above, the hiring of new employees, increased prototype expense and $0.1 million of software license expense all incurred to support the development of Ethernet products. ConferencePlus research and development expenses increased 13% or $0.3 million. The increase was due primarily to shifting employee resources from an information technology support function, which is a part of general and administrative expense, to engineering.

In fiscal year 2010, consolidated research and development expenses declined 31% or $6.2 million. The CNS segment made up the majority of this reduction with $6.0 million of lower expense resulting primarily from the reduction of 13 employees that caused $2.0 million of lower personnel-related expense. Additionally, CNS expense related to Contineo declined $0.8 million and new product investments made in fiscal year 2009 for software and new markets did not continue in fiscal year 2010 and resulted in lower overall research and development spending.

In fiscal year 2011, consolidated G&A expenses decreased 5% or $0.7 million compared to the prior year. CNS and OSP share certain general and administrative resources. The CNS segment received 62% and 65% of these resource costs and the OSP segment has been allocated 38% and 35% of the costs in fiscal years 2011 and 2010, respectively. The Company determines allocation percentages by estimating G&A resources spent supporting each segment.

In fiscal year 2011, CNS general and administrative expense increased 4% or $0.1 million. The change in resource allocations noted above was offset by defense and settlement costs of a patent infringement claim of $0.8 million. OSP general and administrative expense was relatively flat year over year with the change in resource allocations noted above offset by reductions in depreciation and other expenses. ConferencePlus general and administrative expense declined 5% or $0.3 million. The decrease resulted primarily from lower bad debt expense, legal fees, employee-related costs and professional fees as well as a reallocation of employee resources from the information technology support function to engineering, which is part of research and development expenses, as noted above.

Unallocated corporate general and administrative expense decreased 14% or $0.5 million. The decrease primarily resulted from $0.7 million of cumulative prior year stock-based compensation expense that was recorded in fiscal year 2010 to correct errors in stock-based compensation expense related to prior fiscal years. This reduction was offset in part by $0.5 million of expense directly attributable to the sale of CNS business to NETGEAR, which closed April 15, 2011.

In fiscal year 2010, consolidated G&A expense decreased 25% or $4.9 million with the majority of the reduction in the ConferencePlus segment and in the unallocated corporate costs. The CNS and OSP segments share certain general and administrative resources. The CNS segment was allocated 65% of such shared resource costs and the OSP segment was allocated 35% of the shared costs. Fiscal year 2010 reductions in the shared CNS and OSP G&A expense compared to fiscal year 2009 resulted primarily from $0.5 million of severance recorded in fiscal year 2009, lower information technology costs and lower bank fees resulting from a change in line of credit amounts and providers. ConferencePlus segment G&A decreased by 23% due primarily to lower stock-based compensation expense and lower personnel-related costs. The reduction in unallocated corporate costs resulted primarily from legal expenses that were $1.1 million lower and from the non-recurrence of $0.9 million of stock-based compensation expense recorded in fiscal year 2009 that related to the accelerated vesting of restricted stock awards made to Mr. Thomas Mader, a former Chief Executive Officer of the Company. These reductions were offset in part by a non-cash charge of $0.7 million recorded in fiscal year 2010 to correct errors in stock-based compensation expense related to prior fiscal years. Legal expense in fiscal year 2009 included costs related to an SEC investigation, which concluded without enforcement action in fiscal year 2010.

There were no restructuring expenses in fiscal year 2011. In fiscal years 2010 and 2009, the Company had cost reduction initiatives that led to reductions in force in all operating segments that resulted in severance cost for 50 and 20 employees, respectively.

Intangible assets consist primarily of product technology and of customer relationships from previous acquisitions. The reduction in OSP intangible amortization in fiscal year 2010 compared to fiscal year 2009 was due to intangibles from the Teltrend, Inc. acquisition becoming fully amortized at the end of fiscal year 2009.

Goodwill impairment As of March 31, 2011, the Company had $1.1 million, $0.3 million and $0.8 million of goodwill in the ConferencePlus, ConferencePlus Global Services and Noran Tel reporting units, respectively. ConferencePlus and ConferencePlus Global Services are in the ConferencePlus operating segment while Noran Tel is part of the OSP operating segment.

The Company tests goodwill for impairment annually in its fiscal fourth quarter and on an interim basis if indicators of impairment are present. A two-step approach is used to test for goodwill impairment. The first step tests for impairment by comparing the fair value of each reporting unit to its carrying value, including goodwill. The second step, which is performed only if the fair value in step one is lower than the carrying value, measures the amount of impairment by comparing the implied fair value of goodwill to the carrying value of goodwill. The fair value of each reporting unit is estimated using a discounted cash flow methodology and current like-company market transactions. The key assumptions used to determine fair value include the weighted-average cost of capital as well as projections on revenue, costs and capital expenditures.

No impairment was identified during fiscal years 2011 and 2010. Due to the adverse economic environment, an interim impairment test was performed on the Noran Tel reporting unit in the third quarter of fiscal year 2009 that resulted in a $1.4 million charge to adjust goodwill in the unit to its fair value. No impairment was identified in the annual test performed in the fourth quarter of fiscal year 2009.

Other income (expense) Other income (expense), net was $(16,000), $25,000 and $662,000 for fiscal years 2011, 2010, and 2009, respectively. Other income (expense), net was primarily comprised of interest income earned on short-term cash investments and gains or losses on intercompany balances denominated in foreign currency. The decrease in fiscal year 2011 compared to fiscal year 2010 was due primarily to gains or losses on intercompany balances denominated in foreign currency. The decrease in fiscal year 2010 compared to fiscal year 2009 was due primarily to lower short-term interest rates and greater holdings of cash in non-interest-bearing accounts.

Income taxes Income tax in fiscal years 2011 and 2010 was a benefit of $53.3 million and $0.6 million, respectively, compared to expense of $0.1 million for fiscal year 2009. In fiscal year 2011, after considering both the positive and negative evidence, including improved financial performance, expected future taxable income, the exit of a three-year cumulative loss, and the sale of the majority of its CNS business for an estimated $32 million tax gain, the Company concluded that it was more likely than not that it would be able to utilize the majority of its deferred tax assets. Prior to fiscal year 2011, a full valuation allowance on deferred tax assets was in place. As a result of this change in assessment of realizability of deferred tax assets and current year income, the valuation allowance decreased by $60.8 million. A reduction of valuation allowance increases the net deferred tax asset value and adds to net income. Additionally, the Company recognized an additional $0.7 million of tax benefits relating to changes or expiration of uncertain tax positions. In fiscal year 2010, the Company recorded a $0.8 million income tax benefit that was derived from a refund of alternative minimum tax credits. Additionally, the statute of limitations expired on a contingent tax reserve resulting in a $0.4 million tax benefit. The remaining tax expense in fiscal year 2010 resulted from foreign, state and federal alternative minimum tax, as the Company was able to utilize its reserved federal net operating loss carryfowards to offset taxable income.

Minority interest Minority interest expense was $74,000 in fiscal year 2009. Minority interest expense represents the minority interest holder’s share of income for the then 91.5% owned subsidiary, Conference Plus, Inc. The minority interest was purchased by the Company in the third quarter of fiscal year 2009, therefore fiscal years 2011 and 2010 have no minority interest expense.

Discontinued operations In the first quarter of fiscal year 2009, the Company decided to cease the operations of its Westell Limited subsidiary in the UK and closed the facility in the same year. Net loss from discontinued operations was $0.2 million in fiscal year 2009. There were no discontinued operations in fiscal years 2011 and 2010.

Net income (loss) Net income was $67.9 million and $10.3 million in fiscal years 2011 and 2010, respectively, compared to a net loss of $16.6 million fiscal year 2009. The changes were due to the cumulative effects of the variances identified above.

Quarterly Results of Operations

The Company has and may continue to experience fluctuations in quarterly results of operations. Such fluctuations in quarterly results may correspond to substantial fluctuations in the market price of the Class A Common Stock. Some factors which have had an influence on and may continue to influence the Company’s results of operations in a particular quarter include, but are not limited to, the size and timing of customer orders and subsequent shipments, customer order deferrals in anticipation of new products, timing of product introductions or enhancements by the Company or its competitors, market acceptance of new products, technological changes in the telecommunications industry, competitive pricing pressures, accuracy of customer forecasts of end-user demand, write-offs for excess or obsolete inventory, changes in the Company’s operating expenses, personnel changes, foreign currency fluctuations, changes in the mix of products sold, quality control of products sold, disruption in sources of supply, regulatory changes, capital spending, delays of payments by customers, working capital deficits and general economic conditions.

Sales to the Company’s customers typically involve long approval and procurement cycles and can involve large purchase commitments. Accordingly, cancellation or deferral of orders could cause significant fluctuations in the Company’s quarterly results of operations. As a result, the Company believes that period-to-period comparisons of its results of operations are not necessarily meaningful and caution should be used when placing reliance upon such comparisons as indications of future performance.

For a detailed comparison of the eight quarters ended March 31, 2011, see Note 14, Quarterly Results of Operations (Unaudited), in the notes to the financial statements.

Liquidity and Capital Resources

At March 31, 2011, the Company had $86.9 million in cash and cash equivalents and short-term investments, consisting of bank deposits, money market funds and certificates of deposits. At March 31, 2011, the Company had no amounts outstanding and $12.0 million available under its secured revolving credit facility.

The Company does not have any significant debt nor does it have material capital expenditure requirements, balloon payments or other payments due on long term obligations. Off-balance sheet arrangements of the Company include the Enginuity note described in Note 10 of the Consolidated Financial Statements and standard operating leases. Total future obligations and commitments as of March 31, 2011 were $53.5 million. The Company believes that the existing sources of liquidity and cash from operations will satisfy cash flow requirements for the foreseeable future.

The Company entered into a revolving credit agreement with The Private Bank and Trust Company dated as of March 5, 2009 (the “Credit Agreement”) and subsequently entered into amendments to its Credit Agreement to extend the maturity date to March 31, 2012 and amend certain other provisions. The Credit Agreement is an asset-based revolving credit facility in an amount up to $12.0 million based on 80% of eligible accounts receivable plus the lesser of 30% of eligible inventory or $3.0 million. The obligations of the Company under the Credit Agreement are secured by a guaranty from certain direct and indirect domestic subsidiaries of the Company, and by substantially all of the assets of the Company.

The revolving loans under the Credit Agreement bear interest at the greater of the London Interbank Offered Rate (“LIBOR”) plus a spread of 2.25%, or an alternative base rate. The alternative base rate is the greater of prime rate or the Federal Funds rate (the “Base Rate”). The Company is also required to pay a non-use fee of 0.2% per annum on the unused portion of the revolving loans. These charges are waived if the Company maintains with the lender an average monthly non-interest bearing account balance of $5.0 million and an average monthly balance of $15.0 million consisting of other investments. The Company maintained such balances since entering the Credit Agreement.

The Credit Agreement contains financial covenants that include a minimum EBITDA, a minimum tangible net worth and a limitation on capital expenditures for any fiscal year. The Company was in compliance with these covenants on March 31, 2011.

In addition, although the Company has never declared or paid any cash dividends on its common stock and does not anticipate paying any cash dividends in the foreseeable future, the Company’s credit facility restricts the Company’s ability to pay dividends without bank approval.

The Company’s operating activities generated cash of $24.2 million and $17.5 million in fiscal years 2011 and 2010, respectively, and used cash of $14.7 million in fiscal year 2009. Cash generated in fiscal year 2011 resulted primarily from net income adjusted for non-cash items of $17.4 million plus changes in working capital of $6.8 million. Cash generated in fiscal year 2010 resulted primarily from net income adjusted for non-cash items of $16.1 million plus changes in working capital. Cash used in fiscal year 2009 resulted primarily from a net loss of $16.6 million offset by $10.6 million of non-cash items. The change in balance sheet accounts was a use of $8.7 million resulting primarily from increases in inventory, prepaid expenses and accounts receivable.

The Company’s investing activities used $1.3 million, $0.9 million and $3.3 million in fiscal years 2011, 2010 and 2009, respectively. In fiscal year 2011, the Company used $0.8 million on capital expenditures, primarily in its ConferencePlus segment and $0.5 million in purchases of short-term investments. In fiscal year 2010, the Company used $0.9 million on capital expenditures primarily in its ConferencePlus segment for bridging equipment. In fiscal year 2009, the Company used $2.4 million on capital expenditures and $3.7 million to acquire the remaining minority interest of Conference Plus, Inc. Additionally, the Company sold $2.6 million of short-term investments to fund a deferred compensation arrangement. The ConferencePlus segment capital expenditures in fiscal year 2009 were $0.9 million. These expenditures were primarily for teleconference bridge equipment.

The Company’s financing activities provided cash of $2.0 million in fiscal year 2011 and used cash of $1.5 million and $1.4 million in fiscal years 2010 and 2009, respectively. The Company purchased $0.6 million, $1.4 million and $1.6 million of treasury stock in fiscal years 2011, 2010 and 2009, respectively. The Company received proceeds from the exercise of stock options of $2.6 million, $4,000 and $0.1 million in fiscal years 2011, 2010 and 2009, respectively.

Future obligations and commitments as of March 31, 2011 consisted of the following:

On March 17, 2011, the Company entered into a definitive agreement to sell substantially all of the assets of the CNS division, other than certain retained business and Homecloud, to NETGEAR, Inc. for $33.5 million in cash, subject to certain adjustments. The sale was completed on April 15, 2011. Certain purchase obligations in the amount of $12.3 million were assigned to NETGEAR upon completion of the sale. In addition, the Company entered into an agreement with NETGEAR to sublease a portion of the Aurora facility for a minimum period of six months.

As of March 31, 2011, the Company had deferred tax assets of approximately $60.4 million before a valuation allowance of $0.5 million, which reduced the recorded net deferred tax asset to $59.9 million. Also, as of March 31, 2011, the Company had a $6.3 million tax contingency reserve related to uncertain tax positions. The federal net operating loss carryforwards begin to expire in fiscal year 2020. Realization of deferred tax assets associated with the Company’s future deductible temporary differences, net operating loss carryforwards and tax credit carryforwards is dependent upon generating sufficient taxable income prior to their expiration, among other factors. The Company uses estimates of future taxable income to assess the valuation allowance required against deferred tax assets. Management periodically evaluates the recoverability of the deferred tax assets and may adjust the valuation allowance against deferred tax assets accordingly.

Off-Balance Sheet Arrangements

In fiscal year 2005, the Company sold its Data Station Termination product lines and specified fixed assets to Enginuity Communications Corporation (“Enginuity”). The Company provided an unconditional guarantee relating to a 10-year term note payable by Enginuity to a third-party lender that financed the transaction (the “Enginuity Note”). The Enginuity Note had an unpaid balance of $0.7 million as of March 31, 2011. Certain owners of Enginuity personally guaranteed the note and pledged assets as collateral. These personal guarantees will stay in place until the note is paid in full, as will the Company’s. Under the Company’s guarantee, the Company must pay all amounts due under the note payable upon demand from the lender; however, the Company would have recourse against the assets of Enginuity, the personal guarantees, and pledged assets.

The Company evaluated ASC 810 and concluded that Enginuity is a VIE as a result of the debt guarantee. The Company is not considered the primary beneficiary of the VIE and consolidation therefore has not been and is not required.

At the time of the product sale, the Company assessed its obligation under this guarantee pursuant to the provisions of FIN 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, as codified in ASC topic 460, Guarantees (“ASC 460”), and recorded a $0.3 million liability for the value of the guarantee. The balance of the guarantee liability was $0.1 million as of March 31, 2011.

The Company is subject to certain market risks, including foreign currency rate exposures. The Company has foreign subsidiaries in Ireland and Canada that develop and sell products and services in those respective countries and in other countries. The Company is exposed to potential gains and losses from foreign currency fluctuations affecting net investments and earnings denominated in foreign currencies. The Company’s primary future exposure is to changes in exchange rates for the U.S. dollar versus the Euro and Canadian dollar. Approximately 7% of the Company’s fiscal year 2011 revenue was denominated in foreign currencies. The Company estimates market risk as the potential decrease in pretax earnings resulting from a hypothetical decrease in the ending exchange rate of 10%. If such a decrease occurred, the Company would incur approximately $25,000 in additional other expense based on the ending intercompany balance outstanding at March 31, 2011.

As of March 31, 2011, the balance in the cumulative foreign currency translation adjustment account, which is a component of stockholders’ equity, was an unrealized gain of $965,000.

The Company’s Consolidated Financial Statements required by Item 8, together with the reports thereon of the Independent Registered Public Accounting Firm are set forth on pages 37 - 67 of this report and are incorporated by reference in this Item 8. The Consolidated Financial Statement schedule listed under Item 15(a)2, is set forth on page 68 of this report and is incorporated by referenced in this Item 8 and should be read in conjunction with the financial statements.

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of the Company’s senior management, including the Company’s Chief Executive Officer and Chief Financial Officer, the Company conducted an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this annual report (the “Evaluation Date”). Based upon this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded as of the Evaluation Date that the Company’s disclosure controls and procedures were effective such that the information relating to the Company, including consolidated subsidiaries, required to be disclosed in the Company’s Securities and Exchange Commission (“SEC”) reports (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) is accumulated and communicated to the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). There are inherent limitations to the effectiveness of any system of internal control over financial reporting, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even an effective system of internal control over financial reporting can only provide reasonable assurance with respect to financial statement preparation and presentation in accordance with generally accepted accounting principles. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management, with participation of the Company’s Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of the Company’s internal control over financial reporting as of March 31, 2011 based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) and concluded that the Company’s internal control over financial reporting was effective as of March 31, 2011.

The Company’s Independent Registered Public Accounting Firm has issued an audit report on its assessment of the Company’s internal control over financial reporting as of March 31, 2011. This report is included on page 38.

Changes in Internal Control Over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting that occurred during the three months ended March 31, 2011 that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

In the fourth quarter of fiscal year 2011, the Company implemented a new third-party stock-based compensation software solution as previously reported in the Form 10-K for the fiscal year ended March 31, 2010.

None.
