Note 1. Basis of Presentation

Description of Business

Westell Technologies, Inc. (the Company) is a holding company. Its wholly owned subsidiary, Westell, Inc., designs and distributes telecommunications products, which are sold primarily to major telephone companies. Noran Tel, Inc. is a wholly owned subsidiary of Westell, Inc. Noran Tel's operations focus on power distribution product development.

Basis of Presentation and Reporting

The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. The Condensed Consolidated Financial Statements have been prepared using generally accepted accounting principles (GAAP) in the United States for interim financial reporting, and consistent with the instructions of Form 10-Q and Article 10 of Regulation S-X and, accordingly, they do not include all of the information and footnotes required in the annual consolidated financial statements and accompanying footnotes. The Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2016. All intercompany accounts and transactions have been eliminated in consolidation.

In the opinion of management, the unaudited interim financial statements included herein reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the Company’s condensed consolidated financial position and the results of operations, comprehensive income (loss) and cash flows at September 30, 2016, and for all periods presented. The results of operations for the periods presented are not necessarily indicative of the results that may be expected for fiscal year 2017.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and that affect revenue and expenses during the periods reported. Estimates are used when accounting for the allowance for uncollectible accounts receivable, net realizable value of inventory, product warranty accrued, relative selling prices, stock-based compensation, intangible assets fair value, depreciation, income taxes, and contingencies, among other things. Actual results could differ from those estimates.

Recently Issued Accounting Pronouncements Not Yet Adopted

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flow (Topic 230) (ASU 2016-15). This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The update provides new guidance regarding the classification of debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies,

distributions received from equity method investments, beneficial interests in securitized transactions, and separately identifiable cash flows and application of the predominance principle. This standard will be effective for financial statements issued by public companies for the annual and interim periods beginning after December 15, 2017. Early adoption of the standard is permitted. The standard will be applied in a retrospective approach for each period presented. The Company is currently evaluating the potential impact ASU 2016-15 will have on the Company's Consolidated Financial Statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). ASU 2016-13 requires entities to establish an allowance for credit losses for most financial assets. Prior GAAP was based on an incurred loss methodology for recognizing credit losses on financial assets measured at amortized cost and available-for sale debt securities. The update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 31, 2018. The Company does not expect that adoption will have a significant impact on the Company's Consolidated Financial Statements or related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (ASU 2016-02). ASU 2016-02 establishes a comprehensive new lease accounting model. The new standard clarifies the definition of a lease and causes lessees to recognize leases on the

Table of Contents

balance sheet as a lease liability with a corresponding right-of-use asset for leases with a lease term of more than one year. ASU 2016-02 is effective for financial statements issued for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The new standard requires a modified retrospective transition for capital or operating leases existing at or entered into after the beginning of the earliest comparative period presented in the financial statements, but it does not require transition accounting for leases that expire prior to the date of initial application. The Company is currently evaluating the impact that ASU 2016-02 will have on the Company's Consolidated Financial Statements and related disclosures.

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory (ASU 2015-11). The core principle of the guidance is that an entity should measure inventory at the "lower of cost and net realizable value" and options that currently exist for "market value" will be eliminated. The ASU defines net realizable value as the "estimated selling prices in the ordinary course of business, less reasonably predictable cost of completion, disposal, and transportation." The standard is effective for the Company's financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of ASU 2015-11 to have a material impact on its Consolidated Financial Statements or related disclosures.

In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (ASU 2014-15), to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company does not expect the adoption of ASU 2014-15 to have a significant impact on its Consolidated Financial Statements or related disclosures.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASU 2014-09), that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. ASU 2014-09 becomes effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period; early adoption is not permitted. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606) — Deferral of the Effective Date (ASU 2015-14), which defers the effective date of ASU 2014-09 for one year and permits early adoption as early as the original effective date of ASU 2014-09. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. In 2016, the FASB issued additional guidance to clarify the implementation guidance (ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations; ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing; and ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients). The Company is in the process of evaluating the available transition methods and the impact the guidance will have on the Company's Consolidated Financial Statements and related disclosures.

Other accounting standards and recent pronouncements that are not anticipated to have an impact on or are unrelated to the Company’s financial condition, results of operations, cash flows or disclosures are not discussed herein.

Reclassifications

Certain amounts in the Condensed Consolidated Statement of Operations for the three and six months ended September 30, 2015, have been reclassified to conform to the current period presentation. These reclassifications had no impact on previously reported amounts for total stockholders' equity or net income (loss).

Note 2. Restructuring Charges

In the fourth quarter of fiscal year 2015, the Company approved a plan to restructure its business, including reduction of headcount and consolidation of office space within the Aurora headquarters facility, with the intent to optimize operations. The restructuring was substantially completed during the fourth quarter of fiscal year 2015. The Company recognized a restructuring expense of $3.2 million in the three months ended March 31, 2015, inclusive of a non-cash charge of $2.7 million related to a loss on a lease, net of sublease income (the 2015 restructuring). The Company recognized a restructuring expense of $17,000 in the six months ended September 30, 2015.

Table of Contents

In the fourth quarter of fiscal year 2016, the Company approved a plan to restructure its business, including reduction of headcount and lease termination costs related to closing the design center in Canada, to bring operating costs and expenses in-line with anticipated business volumes (the 2016 restructuring). The 2016 restructuring was completed during the fourth quarter of fiscal year 2016, during which the Company recognized a restructuring expense of $0.7 million. All of these costs have been paid as of September 30, 2016.

In the first quarter of fiscal year 2017, the Company approved a restructuring plan (the 2017 restructuring), including discontinuing development of the ClearLink Distributed Antenna System (DAS), a reduction of headcount, and consolidation of facilities in Manchester, NH and Aurora, IL. The Company recognized a restructuring expense of $2.6 million in the three and six months ended September 30, 2016, inclusive of non-cash charges of approximately $1.0 million related to losses on leased facilities, $0.9 million of employee termination costs, and $0.7 million of other associated costs. In addition to the restructuring expense, a $1.2 million impairment charge of fixed assets and $1.6 million of E&O expense for ClearLink DAS inventory and pipeline inventory which was recorded in the six months ended September 30, 2016. The Company expects to incur further restructuring costs of approximately $0.4 million for the remainder of the 2017 restructuring plan. The planned restructuring is scheduled to be substantially completed by March 31, 2017.

As of September 30, 2016, $3.0 million and $0.2 million of the restructuring costs, primarily related to the office space from the 2015 restructuring and 2017 restructuring, are unpaid and accrued on the Condensed Consolidated Balance Sheets presented in accrued restructuring and accrued restructuring non-current, respectively. As of March 31, 2016, $1.5 million and $0.6 million of the restructuring costs, primarily related to the office space from the 2015 restructuring, are unpaid and accrued on the Condensed Consolidated Balance Sheets presented in accrued restructuring and accrued restructuring non-current, respectively. The restructuring costs are expected to be paid in full by the first quarter of fiscal year 2019 concurrent with the termination date of the contractual lease.

Total liability for restructuring charges and their utilization for the six months ended September 30, 2016, and 2015, are summarized as follows:

Note 3. Interim Segment Information

Segment information is presented in accordance with a “management approach", which designates the internal reporting used by the chief operating decision-maker (CODM) for making decisions and assessing performance as the source of the Company's reportable segments. Westell’s Chief Executive Officer is the CODM. In the first quarter of fiscal 2017, the Company re-aligned the business and revised its segments into three reportable operating segments. The CODM continues to define segment profit as gross profit less research and development expenses. In order to provide information that is comparable year to year, fiscal year 2016 segment information has been restated to reflect the new reporting structure. The accounting policies of the segments are the same as those for Westell Technologies, Inc. described in the summary of significant accounting policies included in the Company's Annual Report on Form 10-K for year ended March 31, 2016.

The Company’s three reportable segments are as follows:

In-Building Wireless (IBW) Segment

The IBW segment solutions include distributed antenna systems (DAS) conditioners, high-performance digital repeaters and bi-directional amplifiers (BDAs), and system components and antennas, all used by wireless service providers and neutral-host operators to fine tune radio frequency (RF) signals that helps extend coverage to areas not served well or at all by traditional cell sites.

Intelligent Site Management and Services (ISMS) Segment

The ISMS segment solutions, which were formerly part of the Communications Solutions Group (CSG) segment, are as follows:

Table of Contents

• Intelligent Site Management (ISM) solutions include a suite of remote monitoring and control devices which, when combined with the Company's Optima management software system, provide comprehensive machine-to-machine (M2M) communications that enable operators to remotely monitor, manage, and control site infrastructure and support systems.

• Service offerings include support agreements and deployment services. While the Company currently provides technical support and deployment services primarily for the ISM solution.

Communications Network Solutions (CNS) Segment

The CNS segment solutions, which were also formerly part of the Communications Solutions Group (CSG) segment, are as follows:

Note 5. Stock-Based Compensation

The Westell Technologies, Inc. 2015 Omnibus Incentive Compensation Plan (the 2015 Plan) was approved at the annual meeting of stockholders on September 16, 2015. The 2015 Plan replaced the Westell Technologies, Inc. 2004 Stock Incentive Plan (the 2004 Plan). If any award granted under the 2015 Plan or the 2004 Plan is canceled, terminates, expires, or lapses for any reason, any Shares subject to such award shall again be available for the grant of an award under the 2015 Plan. Shares subject to an award shall not again be made available for issuance under the Plan if such Shares are: (a) shares delivered to or withheld by the Company to pay the grant or purchase price of an award, or (b) shares delivered to or withheld by the Company to pay the withholding taxes related to an award. Any awards or portions thereof that are settled in cash and not in Shares shall not be counted against the foregoing Share limit. The stock options, restricted stock awards, and restricted stock units (RSUs) awarded under the 2015 Plan vest in equal annual installments over 3 years for employees and 1 year for independent directors. The stock options, restricted stock awards, and RSUs awarded under the 2004 Plan vest in equal annual installments over 4 years. Performance stock units (PSUs) earned vest over the performance period, as described below. Certain awards provide for accelerated vesting if there is a change in control (as defined in the 2015 Plan), or when provided within individual employment contracts. The Company recorded incremental stock-based compensation expense of approximately $0.4 million during the three and six months ended September 30, 2016, as a result of accelerated vesting. The Company accounts for forfeitures as they occur. The Company issues new shares for stock awards under the 2015 Plan.

The following table is a summary of total stock-based compensation expense resulting from stock options, restricted stock, RSUs and PSUs, during the six months ended September 30, 2016, and 2015:



	Three months ended September 30,				Six months ended September 30,

Note 6. Product Warranties

The Company’s products carry a limited warranty ranging from one to five years for the products within the IBW segment, and typically one year for products within the ISMS segment, and one to seven years for products within the CNS segment. The specific terms and conditions of those warranties vary depending upon the customer and the products sold. Factors that affect the estimate of the Company’s warranty reserve include: the number of units shipped, anticipated rates of warranty claims, and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liability and adjusts the reserve as necessary. The current portions of the warranty reserve are $228,000 and $229,000 as of September 30, 2016, and March 31, 2016, respectively, and are presented on the Condensed Consolidated Balance Sheets in Accrued expenses. The non-current portions of the warranty reserves are $232,000 and $207,000 as of September 30, 2016, and March 31, 2016, respectively, and are presented on the Condensed Consolidated Balance Sheets in Other non-current liabilities.

Note 7. Variable Interest Entity and Guarantee

The Company has a 50% equity ownership in AccessTel Kentrox Australia PTY LTD (AKA). AKA distributes network management solutions provided by the Company and the other 50% owner to one customer. The Company holds equal voting control with the other owner. All actions of AKA are decided at the board level by majority vote. The Company evaluated ASC 810, Consolidations, and concluded that AKA is a variable interest entity (VIE). The Company has concluded that it is not the primary beneficiary of AKA and, therefore, consolidation is not required. As of September 30, 2016, and March 31, 2016, the carrying amount of the Company's investment in AKA was approximately $0.1 million, which is presented on the Condensed Consolidated Balance Sheets within Other non-current assets.

The Company's revenue from sales to AKA for the three months ended September 30, 2016, and 2015, was $0.6 million and $0.9 million, respectively. The Company's revenue from sales to AKA for the six months ended September 30, 2016, and 2015, was $1.7 million and $1.4 million, respectively. Accounts receivable from AKA was $0.5 million and $0.6 million as of September 30, 2016, and March 31, 2016, respectively. Deferred revenue, which primarily relates to AKA maintenance contracts, was $2.0 million and $1.7 million as of September 30, 2016, and March 31, 2016, respectively. The Company also has provided an unlimited guarantee for the performance of the other 50% owner in AKA, which primarily provides support and engineering services to the customer. This guarantee was put in place at the request of the AKA customer. The guarantee, which is estimated to have a maximum potential future payment of $0.7 million, will stay in place as long as the contract between AKA and the customer is in place. The Company would have recourse against the other 50% owner in AKA in the event the guarantee is triggered. The Company determined that it could perform on the obligation it guaranteed at a positive rate of return and, therefore, did not assign value to the guarantee. The Company's exposure to loss as a result of its involvement with AKA, exclusive of lost profits, is limited to the items noted above.

Note 8. Income Taxes

At the end of each interim period, the Company makes its best estimate of the effective tax rate expected to be applicable for the full fiscal year and uses that rate to provide for income taxes on a current year-to-date basis before discrete items. If a reliable estimate cannot be made, the Company may make a reasonable estimate of the annual effective tax rate, including use of the actual effective rate for the year-to-date. The impact of discrete items is recorded in the quarter in which they occur. The Company utilizes the liability method of accounting for income taxes and deferred taxes, which are determined based on the differences between the financial statements and tax basis of assets and liabilities given the enacted tax laws. The Company evaluates the need for valuation allowances on the net deferred tax assets under the rules of ASC 740, Income Taxes. In assessing the realizability of the Company's deferred tax assets, the Company considered whether it is more likely than not that some or all of the deferred tax assets will be realized through the generation of future taxable income. In making this determination, the Company assessed all of the evidence available at the time, including recent earnings, forecasted income projections and historical performance. The Company determined that the negative evidence outweighed the objectively verifiable positive evidence and previously recorded a full valuation allowance against deferred tax assets. The Company will continue to reassess realizability going forward.

The Company recorded $8,000 and $10,000 of income tax expense in the three and six months ended September 30, 2016, using an effective income tax rate of (0.10)% plus discrete items. The Company recorded $20,000 and $82,000 of income tax benefit in the three and six months ended September 30, 2015, using an effective rate of 1.20% plus discrete items. The effective rate is impacted by the intraperiod allocation as a result of loss from continuing operations and income from discontinued operations, loss in a foreign jurisdiction with no valuation allowance, and states which base tax on gross margin and not pretax income.

Note 9. Commitments and Contingencies

Obligations

Future obligations and commitments, which are comprised of future minimum lease payments, inventory purchase obligations, and contingent consideration, were $9.9 million and $11.8 million at September 30, 2016, and March 31, 2016, respectively.

Purchase obligations relate to inventory that arises in the normal course of business operations. Future obligations and commitments as of September 30, 2016, consisted of the following:



	Payments due within
(in thousands)	Year 1		Year 2		Year 3		Year 4		Year 5		Thereafter		Total
Purchase obligations ⁽¹⁾	$	7,306	$	—	$	—	$	—	$	—	$	—	$	7,306
Future minimum operating lease payments	2,058		373		116		—		—		—		2,547
Future obligations and commitments	$	9,364	$	373	$	116	$	—	$	—	$	—	$	9,853

⁽¹⁾ A reserve for a net loss on firm purchase commitments of $452,000 and $388,000 is recorded on the balance sheet as of September 30, 2016, and March 31, 2016, respectively.

Litigation and Contingency Reserves

The Company and its subsidiaries are involved in various assertions, claims, proceedings and requests for indemnification concerning intellectual property, including patent infringement suits involving technologies that may be incorporated in the Company’s products, which are being handled and defended in the ordinary course of business. These matters are in various stages of investigation and litigation, and they are being vigorously defended. Although the Company does not expect that the outcome in any of these matters, individually or collectively, will have a material adverse effect on its financial condition or results of operations, litigation is inherently unpredictable. Therefore, judgments could be rendered, or settlements entered, that could adversely affect the Company’s operating results or cash flows in a particular period. The Company routinely assesses all of its litigation and threatened litigation as to the probability of ultimately incurring a liability, and it records its best estimate of the ultimate loss in situations where it assesses the likelihood of loss as probable. As of September 30, 2016, and March 31, 2016, the Company has not recorded any contingent liability attributable to existing litigation.

As of March 31, 2015, the Company had total contingency reserves of $0.4 million related to the discontinued operations of ConferencePlus, which was sold in fiscal year 2012. In the six months ended September 30, 2015, a pre-tax gain of $0.4 million resulted from the expiration of an indemnity period and release of a contingency reserve related to the sale of ConferencePlus and was recorded in discontinued operations.

Additionally, the Company had a contingent cash consideration payable related to an acquisition. As of March 31, 2016, the fair value of the contingent consideration liability after offsetting a working capital adjustment and an indemnification claim for warranty obligations was $311,000. As of September 30, 2016, the contingent liability was paid in full. The contingent consideration was based upon the profitability of the acquired products for post-closing periods through June 30, 2016, and was offset by working capital adjustments and other indemnification claims. The maximum earn-out that could have been paid before offsets was $3.5 million. The final calculation performed during the quarter ended June 30, 2016, determined the actual cash payment for the contingent consideration to be $2.1 million.

Note 10. Short-term Investments

As of March 31, 2016, the Company had short-term investments of $10.6 million. There were no short-term investments as of September 30, 2016, as they were all converted to cash equivalents. The Company did not sell any of the investments held as of March 31, 2016, prior to maturity. The fair value of short-term investments approximates their carrying amounts due to the short-term nature of these financial assets and, therefore, there are no unrecognized gains or losses.

Note 11. Fair Value Measurements

Fair value is defined by ASC 820, Fair Value Measurements and Disclosures (ASC 820), as the price that would be received upon selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

Table of Contents


•	Level 1 – Quoted prices in active markets for identical assets and liabilities.


•	Level 2 – Quoted prices in active markets for similar assets and liabilities, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.


•	Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

The Company’s money market funds are measured using Level 1 inputs. The contingent consideration described in Note 9 was measured using Level 3 inputs.

The following table presents available-for sale securities and non-financial liabilities measured at fair value on a recurring basis as of September 30, 2016:



(in thousands)	Total Fair Value of Asset or Liability		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)	Balance Sheet Classification
Assets:
Money market funds	$	17,129	$	17,129	—	—	Cash and cash equivalents

The following table presents available-for sale securities and non-financial liabilities measured at fair value on a recurring basis as of March 31, 2016:



(in thousands)	Total Fair Value of Asset or Liability		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)		Balance Sheet Classification

Money market funds	$	10,043	$	10,043	—	—		Cash and cash equivalents
Liabilities:
Contingent consideration, current	$	311	—		—	$	311	Contingent consideration payable

The fair value of the money market funds approximates their carrying amounts due to the short-term nature of these financial assets.

In connection with an acquisition in the quarter ended June 30, 2012, payment of a portion of the purchase price was contingent upon the profitability of the acquired products for post-closing periods through June 30, 2016, and was offset by working capital adjustments and other indemnification claims. The Company estimated the fair value of contingent consideration as the present value of the expected payments over the term of the arrangement based on financial forecasts of future profitability of the acquired products, and reaching the forecast. The final calculation performed during the quarter ended June 30, 2016, determined the actual cash payment for the contingent consideration to be $2.1 million, which was paid in full as of September 30, 2016.

The fair value measurement of contingent consideration as of March 31, 2016, encompasses the following significant unobservable inputs:



($ in thousands)	Unobservable Inputs
	March 31, 2016
Estimated earn-out contingent consideration	$	2,968

Note 12. Share Repurchases

In August 2011, the Board of Directors authorized a share repurchase program whereby the Company may repurchase up to an aggregate of $20.0 million of its outstanding Class A Common Stock (the authorization). There were no shares repurchased under this authorization during the six months ended September 30, 2016, or September 30, 2015. There was approximately $0.1 million remaining for additional share repurchases under this program as of September 30, 2016.

Additionally, in the six months ended September 30, 2016, and September 30, 2015, the Company repurchased 166,176 and 73,765 shares of Class A Common Stock, respectively, from certain employees that were surrendered to satisfy the minimum statutory tax withholding obligations on the vesting of restricted stock, RSUs and PSUs. These repurchases are not included in the authorized share repurchase program and had a weighted-average purchase price of $0.85 and $1.15 per share, respectively.

Note 13. Intangible and Long-Lived Assets

Intangible Assets

Intangible assets include customer relationships, trade names, developed technology and other intangibles. Intangible assets with determinable lives are amortized over their estimated useful lives. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment loss is recorded for the excess of the asset’s carrying amount over its fair value.

During fiscal year 2017, the Company experienced triggering events in the first and second quarters that resulted in the Company testing its intangible assets for impairment. As a result of the Company reorganizing its reporting structure in the first quarter of fiscal year 2017, the Company reassigned assets and liabilities to reporting units. In evaluating whether it is more likely than not that the fair value of the Company's reporting units were less than their carrying value, the Company assessed all relevant events and circumstances and determined that, due to the overall financial performance of the Company and recent change in reporting structure, indicators of impairment were present. The Company performed an evaluation to test IBW, ISMS and CNS intangible assets for recoverability and concluded there was no impairment during the six months ended September 30, 2016, in any of the reporting units.

Long-lived Assets

Long-lived assets consist of property and equipment. Long-lived assets that are held and used should be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the long-lived assets might not be recoverable. Due to a significant adverse change in the business climate connected to the ClearLink DAS development project, the Company determined indicators of impairment were present as of June 30, 2016. The Company determined that equipment related to development and manufacturing of this product were fully impaired and recorded an impairment charge of $1.2 million. Long-lived asset impairment charges are presented in long-lived asset impairment on the Condensed Consolidated Statements of Operations. See Note 2 Restructuring Charges.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

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

Table of Contents

Westell Technologies, Inc., (the Company) is a leading provider of in-building wireless, intelligent site management, cell site optimization, and outside plant solutions focused on innovation and differentiation at the edge of telecommunication networks, where end users connect. The Company’s comprehensive set of products and solutions are designed to advance network performance for carriers, integrators, and other network operators, allowing them to reduce operating costs and improve network performance. With millions of products successfully deployed worldwide, the Company is a trusted partner for transforming networks into high performance, reliable systems.

In the first quarter of fiscal 2017, the Company re-aligned the business and revised its segments into three reportable operating segments, which are: In-Building Wireless, Intelligent Site Management and Services, and Communications Network Solutions.

In-Building Wireless (IBW) Segment

Intelligent Site Management and Services (ISMS) Segment

The ISMS segment solutions, which were formerly part of the Communications Solutions Group (CSG) segment, are as follows:

• Service offerings include support agreements and deployment services. While the Company currently provides technical support and deployment services primarily for the ISM solution.

Communications Network Solutions (CNS) Segment

The CNS segment solutions, which were also formerly part of the Communications Solutions Group (CSG) segment, are as follows:

Customers

The Company’s customer base for its products is highly concentrated and includes telecommunications service providers, systems integrators, cell tower operators, and distributors. Telecommunication service providers include wireless and wireline service providers, multiple systems operators (MSOs), and Internet Service Providers (ISPs). Due to the stringent customer quality specifications and the regulated environment in which customers operate, the Company must undergo lengthy approval and procurement processes prior to selling most of 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. The prices for the Company's products vary based upon volume, customer specifications, and other criteria, and they are subject to change for a variety of reasons, including cost and competitive factors.

To remain competitive, the Company must continue to invest in new product development and 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 meeting technical specifications 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 invest in product research and development activities.

In view of the Company’s reliance on the telecommunications market for revenues, the project nature of the business, the unpredictability of orders, and pricing pressures, the Company believes that period-to-period comparisons of its financial results should not be relied upon as an indication of future performance. The Company has experienced quarterly fluctuations in customer ordering and purchasing activity due primarily to the project-based nature of the business and to budgeting and procurement patterns toward the end of the calendar year or the beginning of a new year. While these factors can result in the

greatest fluctuations in the Company's third and fourth fiscal quarters, this is not always consistent and may not always correlate to financial results.

On September 27, 2016, the Company announced that the Board of Directors has appointed Kirk R. Brannock as Interim President and Chief Executive Officer. The Company also announced that Dennis O. Harris, a Director of the Company since January 2010, has been appointed interim Chairman of the Board. Along with these management changes, the Company is executing a plan to reduce its operating cost structure to more quickly return to profitability and generate stockholder value, while focusing on sales and product development initiatives.

Results of Operations

Below is a table that compares revenue for the three and six months ended September 30, 2016, and 2015, by segment.

Revenue



	Three months ended September 30,							Six months ended September 30,
(in thousands)	2016		2015		Change			2016		2015		Change
IBW	$	6,644	$	10,819	$	(4,175	)	$	12,765	$	19,889	$	(7,124	)
ISMS	5,109		5,886		(777		)	9,248		10,391		(1,143		)
CNS	6,027		8,809		(2,782		)	10,583		16,804		(6,221		)
Consolidated revenue	$	17,780	$	25,514	$	(7,734	)	$	32,596	$	47,084	$	(14,488	)

IBW revenue was $6.6 million and $12.8 million in the three and six months ended September 30, 2016, compared to $10.8 million and $19.9 million in the same periods in the prior year. The decrease in revenue in both the three and six month periods was due primarily to decreases in sales of DAS conditioners offset in part by increased sales of repeater products.

ISMS revenue was $5.1 million and $9.2 million in the three and six months ended September 30, 2016, compared to $5.9 million and $10.4 million in the same periods in the prior year. The decrease in revenue in both the three and six month periods was due primarily to lower deployment services revenue for ISM remotes and tower mounted amplifiers.

CNS revenue was $6.0 million and $10.6 million in the three and six months ended September 30, 2016, compared to $8.8 million and $16.8 million, in the same periods in the prior year. The decrease in the three months ended September 30, 2016, compared to the same period in the prior year was primarily due to lower carrier spend in TMAs and Sonet/TDM. The decrease in the six months ended September 30, 2016, compared to the same period in the prior year was primarily due to significantly lower carrier spending in TMAs and lower spending overall in OSP.

Gross Margin



	Three months ended September 30,						Six months ended September 30,
	2016		2015		Change		2016		2015		Change
IBW	33.6	%	42.0	%	(8.4	)%	25.3	%	43.0	%	(17.7	)%
ISMS	47.1	%	53.8	%	(6.7	)%	47.9	%	51.7	%	(3.8	)%
CNS	28.7	%	28.6	%	0.1	%	31.0	%	28.2	%	2.8	%
Consolidated gross margin	35.8	%	40.1	%	(4.3	)%	33.5	%	39.6	%	(6.1	)%

Gross margin in the IBW segment was 33.6% and 25.3% in the three and six months ended September 30, 2016, compared to 42.0% and 43.0% in the same periods in the prior year. The lower gross margins in the six months ended September 30, 2016, is primarily due to higher excess and obsolete inventory expense of $1.2 million in fiscal year 2017. In addition, overall revenue levels contributed to the lower gross margin due to the under absorption of fixed costs.

Gross margin in the ISMS segment was 47.1% and 47.9% in the three and six months ended September 30, 2016, compared to 53.8% and 51.7% in the same periods in the prior year. The decrease in gross margin is primarily due to higher costs in deployment services.

Gross margin in the CNS segment was 28.7% and 31.0% in the three and six months ended September 30, 2016, compared to 28.6% and 28.2% in the same periods in the prior year. The increase in gross margin in both the three and six month periods was primarily due to a more favorable product mix.

Consolidated research and development costs decreased by $1.3 million and $2.1 million in the three and six months ended September 30, 2016, compared to the same periods in the prior year. Research and development expense in the IBW segment decreased by $1.2 million and $2.0 million in the three and six months ended September 30, 2016, compared to the same periods in the prior year due to $1.1 million and $1.6 million of decreased manpower related expenses in the three and six months ended September 30, 2016, respectively, and $0.4 million of prototype expense in the six months ended September 30, 2016. The decrease in expenses were primarily associated with the ClearLink DAS development project.

Sales and Marketing



	Three months ended September 30,							Six months ended September 30,
(in thousands)	2016		2015		Change			2016		2015		Change
Consolidated sales and marketing expense	$	2,896	$	4,113	$	(1,217	)	$	6,277	$	7,309	$	(1,032	)

Sales and marketing expense was $2.9 million and $6.3 million in the three and six months ended September 30, 2016, compared to $4.1 million and $7.3 million in same periods in the prior year. The decrease was due primarily to lower payroll and headcount related expenses in our sales organization.

General and Administrative



	Three months ended September 30,							Six months ended September 30,
(in thousands)	2016		2015		Change			2016		2015		Change
Consolidated general and administrative expense	$	2,218	$	2,493	$	(275	)	$	4,563	$	5,462	$	(899	)

Consolidated general and administrative expense decreased $0.3 million and $0.9 million in the three and six months ended September 30, 2016, compared to the same periods in the prior fiscal year primarily to lower payroll and headcount related expenses.

Intangible amortization



	Three months ended September 30,							Six months ended September 30,
(in thousands)	2016		2015		Change			2016		2015		Change
Consolidated intangible amortization	$	1,201	$	1,432	$	(231	)	$	2,401	$	2,831	$	(430	)

The intangible assets consist of product technology, customer relationships, trade names, and backlog derived from acquisitions. The decrease in the three and six months ended September 30, 2016, compared to the same periods in the prior fiscal year resulted primarily from product and customer related intangibles from the acquisition of HyperEdge and the non-compete from the Kentrox acquisition becoming fully amortized.

Restructuring

In the first quarter of fiscal year 2017, the Company approved a restructuring plan (the 2017 restructuring), including discontinuing development of the ClearLink Distributed Antenna System (DAS), a reduction of headcount, and consolidation of facilities in Manchester, NH and Aurora, IL. The Company recognized a restructuring expense of $2.6 million in the six months ended September 30, 2016, inclusive of non-cash charges of approximately $1.0 million related to losses on leased facilities, $0.9 million of employee termination costs, and $0.7 million of other associated costs. The Company expects to incur further restructuring costs of approximately $0.4 million for the remainder of the 2017 restructuring plan. The planned restructuring is scheduled to be substantially completed by March 31, 2017.

Table of Contents

The Company recorded restructuring expense of $17,000 in the six months ended September 30, 2015, related to severance for terminated employees associated with the CSI acquisition.

Long-lived assets impairment

Due to a significant adverse change in the business climate connected to the ClearLink DAS development project, the Company determined indicators of impairment were present as of June 30, 2016. The Company determined that equipment related to development and manufacturing of this product were fully impaired and recorded an impairment charge of $1.2 million during the three months ended June 30, 2016. There were no long-lived assets impaired during the three months ended September 30, 2016, or the six months ended June 30, 2015.

Other income (expense)



	Three months ended September 30,							Six months ended September 30,
(in thousands)	2016		2015			Change		2016		2015			Change
Consolidated other income (expense)	$	74	$	(61	)	$	135	$	91	$	(23	)	$	114

Other income (expense) contains interest income earned on short-term investments and foreign currency gains and losses. The foreign currency impacts related primarily to the receivables and cash denominated in Australian and Canadian currencies.

Income tax benefit (expense)

The Company recorded $8,000 and $10,000 of income tax expense in the three and six months ended September 30, 2016, using an effective income tax rate of (0.10)% plus discrete items. The Company recorded $20,000 and $82,000 of income tax benefit in the three and six months ended September 30, 2015, using an effective rate of 1.20% plus discrete items. The September 30, 2015, effective rate is impacted by the intraperiod allocation as a result of loss from continuing operations and income from discontinued operations, loss in a foreign jurisdiction with no valuation allowance, and states which base tax on gross margin and not pretax income.

Discontinued operations

The fiscal year 2016 income from discontinued operations resulted from the expiration of an indemnity period and release of a contingency reserve related to the sale of ConferencePlus.

Net income (loss)

Net loss was $5.8 million and $13.6 million in the three and six months ended September 30, 2016, respectively, and $2.5 million and $6.3 million in the three and six months ended September 30, 2015, respectively. The changes were a result of the cumulative effects of the variances identified above.

Liquidity and Capital Resources

Overview

At September 30, 2016, the Company had $20.9 million in cash and cash equivalents consisting of bank deposits and government money market funds.

The Company believes that the existing sources of liquidity and cash from operations will satisfy cash flow requirements for the foreseeable future.

Future obligations and commitments, which are principally comprised of future minimum lease payments and inventory purchase obligations, were $9.9 million and $11.8 million at September 30, 2016, and March 31, 2016, respectively.

Table of Contents

Purchase obligations consist of inventory that arises in the normal course of business operations. Future obligations and commitments as of September 30, 2016, consisted of the following:



	Payments due within
(in thousands)	1 year		2 years		3 years		4 years		5 years		Thereafter		Total
Purchase obligations ⁽¹⁾	$	7,306	$	—	$	—	$	—	$	—	$	—	$	7,306

Future obligations and commitments	$	9,364	$	373	$	116	$	—	$	—	$	—	$	9,853

(1) A reserve for a net loss on firm purchase commitments of $452,000 and $388,000 is recorded on the balance sheet as of September 30, 2016, and March 31, 2016, respectively. The increase as of September 30, 2016, is primarily due to ClearLink DAS purchase commitments. See Note 2, Restructuring Charges.

Cash Flows

The Company’s operating activities used cash of $8.0 million in the six months ended September 30, 2016, which resulted primarily from a $13.6 million net loss, adjusted for non-cash charges of $8.1 million of amortization, depreciation, long-lived asset impairments,restructuring, and stock-based compensation expense, and a $2.5 million increase in net working capital. The Company’s investing activities provided cash of $10.1 million, which resulted primarily from the net maturities of short-term investments of $10.6 million offset in part by $0.5 million of capital equipment purchases. In the six months ended September 30, 2016, the Company’s financing activities used $0.3 million of cash resulting primarily from payment of contingent consideration.

As of September 30, 2016, the Company had net deferred tax assets of approximately $46.3 million before a valuation allowance of $46.4 million, resulting in a net deferred tax liability of $24,000. Also, as of September 30, 2016, the Company had a $3.0 million tax contingency reserve related to uncertain tax positions which is offset against deferred tax assets. The federal net operating loss carryforward begins to expire in fiscal year 2023. 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 weighed positive and negative evidence to assess the need for a valuation allowance against deferred tax assets and whether a tax benefit should be recorded when taxable losses are incurred. The existence of a valuation allowance does not limit the availability of tax assets to reduce taxes payable when taxable income arises. 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

The Company has a 50% equity ownership in AccessTel Kentrox Australia PTY LTD (AKA). AKA distributes network management solutions provided by the Company and the other 50% owner to one customer. The Company holds equal voting control with the other owner. All actions of AKA are decided at the board level by majority vote. The Company also has provided an unlimited guarantee for the performance of the other 50% owner in AKA, which primarily provides support and engineering services to the customer. This guarantee was put in place at the request of the AKA customer. The guarantee, which is estimated to have a maximum potential future payment of $0.7 million, will stay in place as long as the contract between AKA and the customer is in place. The Company would have recourse against the other 50% owner in AKA in the event the guarantee is triggered. The Company determined that it could perform on the obligation it guaranteed at a positive rate of return and, therefore, did not assign value to the guarantee.

Critical Accounting Policies

A complete description of the Company’s significant accounting policies is discussed in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2016. There have been no material changes in the Company's critical accounting policies from those disclosed in the Annual Report on Form 10-K for the year ended March 31, 2016.

ITEM 4. CONTROLS AND PROCEDURES

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 quarterly report (the Evaluation Date). Based on 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.

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 quarter ended September 30, 2016, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Company is involved in various legal proceedings incidental to the Company’s business and its previously owned operations. In the ordinary course of business, the Company is routinely audited and subject to inquiries by governmental and regulatory agencies. Although it is not possible to predict with certainty the outcome of these or other unresolved legal actions or the range of possible loss, management believes that the outcome of such proceedings will not have a material adverse effect on the Company's consolidated operations or financial condition.

ITEM 1A. RISK FACTORS

See “Risk Factors” in Part 1 – Item 1A of the Company's Annual Report on Form 10-K for the year ended March 31, 2016, for information about risk factors. There have been no material changes in the Company's risk factors from those disclosed in the Company's Annual Report on Form 10-K for the year ended March 31, 2016, except as follows:

Risks Related to Our Business

We may experience significant delays or other complications in the design, manufacture, launch, and production ramp of new products, which could harm our business, prospects, financial condition, and operating results.

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. Additionally, other companies may succeed in developing and marketing products that are more effective and/or less costly than any product we may develop, or that are commercially accepted before any of our products. 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, particularly as customer demand shifts to new technology or the next generation of products. 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, our product sales will decrease and our competitive position, financial condition and results of operations would be materially and adversely affected. We have experience development delays in the past and may experience significant delays or other complications in bringing to market and ramping production of new products. Recently, we suspended future development of our ClearLink DAS product due to competitive products to ClearLink DAS in the market that have already launched and considerable gross margin depression on the product. The decision to suspend ClearLink DAS or other complications in the development, manufacture, launch, and production ramp of any other future product, could materially damage our business, prospects, financial condition, and operating results.

Risks Related to our Common Stock

Our Class A Common Stock could be delisted from the NASDAQ Global Select Market.

NASDAQ has established certain standards for the continued listing of a security on the NASDAQ Global Select Market. The standards for continued listing include, among other things, that the minimum bid price for the listed securities be at least $1.00 per share. Under these rules, a security is considered deficient if it fails to achieve at least a $1.00 closing bid price for a period of 30 consecutive business days. On July 1, 2016, we received a notification (the "Notice") from the Listing Qualifications Department of The NASDAQ Stock Market that the bid price for the Company’s Class A Common Stock has closed below the minimum $1.00 per share for 30 consecutive trading days in conflict with the NASDAQ rules for continued listing.

The Notice indicates we will be provided 180 calendar days, or until December 28, 2016, to regain compliance with the minimum $1.00 per share bid requirement. The Notice further indicates that the Company may regain compliance with the Rule if at any time before December 28, 2016, the bid price of the Company’s common stock closes at $1.00 per share or above for a minimum of 10 consecutive business days. In the event the Company does not regain compliance with the Rule by December 28, 2016, the Company may be eligible for an additional 180 calendar day compliance period if it elects to transfer to The NASDAQ Capital Market to take advantage of the additional compliance period offered on that market. To qualify, the Company would be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The NASDAQ Capital Market, with the exception of the bid price requirement, and would need to provide written notice of its intention to cure the bid price deficiency during the second compliance period.

Table of Contents

If the closing bid price of our Class A Common Stock continues to fail to meet NASDAQ's minimum closing bid price requirement, or if we otherwise fail to meet all other applicable NASDAQ requirements, NASDAQ may make a determination to delist our Class A common stock. Any such delisting could adversely affect the market liquidity of our Class A Common Stock and the market price of our Class A Common Stock could decrease. A delisting could adversely affect our ability to obtain financing for our operations and/or result in a loss of confidence by investors, customers, suppliers or employees.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Issuer Purchases of Equity Securities

The following table provides information about the Company’s repurchase activity for its Class A Common Stock during the three months ended September 30, 2016.

Total	93,658	$	0.6097	—	$	112,741

(a)

In the three months ended September 30, 2016, the Company repurchased 93,658 shares from employees that were surrendered to satisfy the minimum statutory tax withholding obligations on the vesting of restricted stock, restricted stock units and performance-based restricted stock units. These repurchases were not included in the authorized share repurchase program and had a weighted-average purchase price of $0.61 per share.


(b)	In August 2011, the Board of Directors authorized a share repurchase program whereby the Company may repurchase up to an additional aggregate of $20.0 million of its outstanding Class A Common Stock. There was approximately $0.1 million remaining under this program as of September 30, 2016.

Items 3, 4 and 5 are not applicable and have been omitted.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Description of Business Westell Technologies, Inc. (the Company) is a holding company. Its wholly owned subsidiary, Westell, Inc., designs and distributes telecommunications products, which are sold primarily to major telephone companies. Noran Tel, Inc. is a wholly owned subsidiary of Westell, Inc. Noran Tel's operations focus on power distribution product development. Basis of Presentation and Reporting The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. The Condensed Consolidated Financial Statements have been prepared using generally accepted accounting principles (GAAP) in the United States for interim financial reporting, and consistent with the instructions of Form 10-Q and Article 10 of Regulation S-X and, accordingly, they do not include all of the information and footnotes required in the annual consolidated financial statements and accompanying footnotes. The Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2016. All intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the unaudited interim financial statements included herein reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the Company’s condensed consolidated financial position and the results of operations, comprehensive income (loss) and cash flows at September 30, 2016, and for all periods presented. The results of operations for the periods presented are not necessarily indicative of the results that may be expected for fiscal year 2017. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and that affect revenue and expenses during the periods reported. Estimates are used when accounting for the allowance for uncollectible accounts receivable, net realizable value of inventory, product warranty accrued, relative selling prices, stock-based compensation, intangible assets fair value, depreciation, income taxes, and contingencies, among other things. Actual results could differ from those estimates. Recently Issued Accounting Pronouncements Not Yet Adopted In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flow (Topic 230) (ASU 2016-15). This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The update provides new guidance regarding the classification of debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitized transactions, and separately identifiable cash flows and application of the predominance principle. This standard will be effective for financial statements issued by public companies for the annual and interim periods beginning after December 15, 2017. Early adoption of the standard is permitted. The standard will be applied in a retrospective approach for each period presented. The Company is currently evaluating the potential impact ASU 2016-15 will have on the Company's Consolidated Financial Statements and related disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). ASU 2016-13 requires entities to establish an allowance for credit losses for most financial assets. Prior GAAP was based on an incurred loss methodology for recognizing credit losses on financial assets measured at amortized cost and available-for sale debt securities. The update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 31, 2018. The Company does not expect that adoption will have a significant impact on the Company's Consolidated Financial Statements or related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (ASU 2016-02). ASU 2016-02 establishes a comprehensive new lease accounting model. The new standard clarifies the definition of a lease and causes lessees to recognize leases on the balance sheet as a lease liability with a corresponding right-of-use asset for leases with a lease term of more than one year. ASU 2016-02 is effective for financial statements issued for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The new standard requires a modified retrospective transition for capital or operating leases existing at or entered into after the beginning of the earliest comparative period presented in the financial statements, but it does not require transition accounting for leases that expire prior to the date of initial application. The Company is currently evaluating the impact that ASU 2016-02 will have on the Company's Consolidated Financial Statements and related disclosures. In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory (ASU 2015-11). The core principle of the guidance is that an entity should measure inventory at the "lower of cost and net realizable value" and options that currently exist for "market value" will be eliminated. The ASU defines net realizable value as the "estimated selling prices in the ordinary course of business, less reasonably predictable cost of completion, disposal, and transportation." The standard is effective for the Company's financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of ASU 2015-11 to have a material impact on its Consolidated Financial Statements or related disclosures. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (ASU 2014-15), to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company does not expect the adoption of ASU 2014-15 to have a significant impact on its Consolidated Financial Statements or related disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASU 2014-09), that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. ASU 2014-09 becomes effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period; early adoption is not permitted. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606) — Deferral of the Effective Date (ASU 2015-14), which defers the effective date of ASU 2014-09 for one year and permits early adoption as early as the original effective date of ASU 2014-09. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. In 2016, the FASB issued additional guidance to clarify the implementation guidance (ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations; ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing; and ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients). The Company is in the process of evaluating the available transition methods and the impact the guidance will have on the Company's Consolidated Financial Statements and related disclosures. Other accounting standards and recent pronouncements that are not anticipated to have an impact on or are unrelated to the Company’s financial condition, results of operations, cash flows or disclosures are not discussed herein. Reclassifications Certain amounts in the Condensed Consolidated Statement of Operations for the three and six months ended September 30, 2015, have been reclassified to conform to the current period presentation. These reclassifications had no impact on previously reported amounts for total stockholders' equity or net income (loss).

Variable Interest Entity and Guarantee (Notes)	6 Months Ended
Variable Interest Entity and Guarantee (Notes)	Sep. 30, 2016
Guarantees [Abstract]
Equity Method Investment [Text Block]	Variable Interest Entity and Guarantee The Company has a 50% equity ownership in AccessTel Kentrox Australia PTY LTD (AKA). AKA distributes network management solutions provided by the Company and the other 50% owner to one customer. The Company holds equal voting control with the other owner. All actions of AKA are decided at the board level by majority vote. The Company evaluated ASC 810, Consolidations, and concluded that AKA is a variable interest entity (VIE). The Company has concluded that it is not the primary beneficiary of AKA and, therefore, consolidation is not required. As of September 30, 2016, and March 31, 2016, the carrying amount of the Company's investment in AKA was approximately $0.1 million, which is presented on the Condensed Consolidated Balance Sheets within Other non-current assets. The Company's revenue from sales to AKA for the three months ended September 30, 2016, and 2015, was $0.6 million and $0.9 million, respectively. The Company's revenue from sales to AKA for the six months ended September 30, 2016, and 2015, was $1.7 million and $1.4 million, respectively. Accounts receivable from AKA was $0.5 million and $0.6 million as of September 30, 2016, and March 31, 2016, respectively. Deferred revenue, which primarily relates to AKA maintenance contracts, was $2.0 million and $1.7 million as of September 30, 2016, and March 31, 2016, respectively. The Company also has provided an unlimited guarantee for the performance of the other 50% owner in AKA, which primarily provides support and engineering services to the customer. This guarantee was put in place at the request of the AKA customer. The guarantee, which is estimated to have a maximum potential future payment of $0.7 million, will stay in place as long as the contract between AKA and the customer is in place. The Company would have recourse against the other 50% owner in AKA in the event the guarantee is triggered. The Company determined that it could perform on the obligation it guaranteed at a positive rate of return and, therefore, did not assign value to the guarantee. The Company's exposure to loss as a result of its involvement with AKA, exclusive of lost profits, is limited to the items noted above.

Income Taxes (Notes)	Sep. 30, 2016
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At the end of each interim period, the Company makes its best estimate of the effective tax rate expected to be applicable for the full fiscal year and uses that rate to provide for income taxes on a current year-to-date basis before discrete items. If a reliable estimate cannot be made, the Company may make a reasonable estimate of the annual effective tax rate, including use of the actual effective rate for the year-to-date. The impact of discrete items is recorded in the quarter in which they occur. The Company utilizes the liability method of accounting for income taxes and deferred taxes, which are determined based on the differences between the financial statements and tax basis of assets and liabilities given the enacted tax laws. The Company evaluates the need for valuation allowances on the net deferred tax assets under the rules of ASC 740, Income Taxes. In assessing the realizability of the Company's deferred tax assets, the Company considered whether it is more likely than not that some or all of the deferred tax assets will be realized through the generation of future taxable income. In making this determination, the Company assessed all of the evidence available at the time, including recent earnings, forecasted income projections and historical performance. The Company determined that the negative evidence outweighed the objectively verifiable positive evidence and previously recorded a full valuation allowance against deferred tax assets. The Company will continue to reassess realizability going forward. The Company recorded $8,000 and $10,000 of income tax expense in the three and six months ended September 30, 2016, using an effective income tax rate of (0.10)% plus discrete items. The Company recorded $20,000 and $82,000 of income tax benefit in the three and six months ended September 30, 2015, using an effective rate of 1.20% plus discrete items. The effective rate is impacted by the intraperiod allocation as a result of loss from continuing operations and income from discontinued operations, loss in a foreign jurisdiction with no valuation allowance, and states which base tax on gross margin and not pretax income.

Short-term Investments [Abstract]
Short-term Investments	Short-term Investments As of March 31, 2016, the Company had short-term investments of $10.6 million. There were no short-term investments as of September 30, 2016, as they were all converted to cash equivalents. The Company did not sell any of the investments held as of March 31, 2016, prior to maturity. The fair value of short-term investments approximates their carrying amounts due to the short-term nature of these financial assets and, therefore, there are no unrecognized gains or losses.

Share Repurchases (Notes)	Sep. 30, 2016
Payments for Repurchase of Equity [Abstract]
Share Repurchases	Share Repurchases In August 2011, the Board of Directors authorized a share repurchase program whereby the Company may repurchase up to an aggregate of $20.0 million of its outstanding Class A Common Stock (the authorization). There were no shares repurchased under this authorization during the six months ended September 30, 2016, or September 30, 2015. There was approximately $0.1 million remaining for additional share repurchases under this program as of September 30, 2016. Additionally, in the six months ended September 30, 2016, and September 30, 2015, the Company repurchased 166,176 and 73,765 shares of Class A Common Stock, respectively, from certain employees that were surrendered to satisfy the minimum statutory tax withholding obligations on the vesting of restricted stock, RSUs and PSUs. These repurchases are not included in the authorized share repurchase program and had a weighted-average purchase price of $0.85 and $1.15 per share, respectively.

Intangibles and other Long-Lived Assets (Notes)	Sep. 30, 2016
Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets Disclosure [Text Block]	Intangible and Long-Lived Assets Intangible Assets Intangible assets include customer relationships, trade names, developed technology and other intangibles. Intangible assets with determinable lives are amortized over their estimated useful lives. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment loss is recorded for the excess of the asset’s carrying amount over its fair value. During fiscal year 2017, the Company experienced triggering events in the first and second quarters that resulted in the Company testing its intangible assets for impairment. As a result of the Company reorganizing its reporting structure in the first quarter of fiscal year 2017, the Company reassigned assets and liabilities to reporting units. In evaluating whether it is more likely than not that the fair value of the Company's reporting units were less than their carrying value, the Company assessed all relevant events and circumstances and determined that, due to the overall financial performance of the Company and recent change in reporting structure, indicators of impairment were present. The Company performed an evaluation to test IBW, ISMS and CNS intangible assets for recoverability and concluded there was no impairment during the six months ended September 30, 2016, in any of the reporting units. Long-lived Assets Long-lived assets consist of property and equipment. Long-lived assets that are held and used should be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the long-lived assets might not be recoverable. Due to a significant adverse change in the business climate connected to the ClearLink DAS development project, the Company determined indicators of impairment were present as of June 30, 2016. The Company determined that equipment related to development and manufacturing of this product were fully impaired and recorded an impairment charge of $1.2 million. Long-lived asset impairment charges are presented in long-lived asset impairment on the Condensed Consolidated Statements of Operations. See Note 2 Restructuring Charges.
