Note 1. The Company and Basis of Presentation

The Company

Aviat Networks, Inc. (the "Company," "we," "us," and "our") designs, manufactures and sells a range of wireless networking solutions and services to mobile and fixed telephone service providers, private network operators, government agencies, transportation and utility companies, public safety agencies and broadcast system operators across the globe. Our products include broadband wireless access base stations and customer premises equipment for fixed and mobile, point-to-point digital microwave radio systems for access, backhaul, trunking and license-exempt applications, supporting new network deployments, network expansion, and capacity upgrades.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared by us in accordance with generally accepted accounting principles in the United States ("U.S. GAAP") and with the rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial information. Accordingly, the statements do not include all information and footnotes required by U.S. GAAP for annual consolidated financial statements. In the opinion of our management, such interim financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of financial position, results of operations and cash flows for such periods. The results for the quarter ended April 1, 2016 (the " third quarter and first three quarters of fiscal 2016 ") are not necessarily indicative of the results that may be expected for the full fiscal year or future operating periods. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations" and the consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the fiscal year ended July 3, 2015 .

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries. Significant intercompany transactions and accounts have been eliminated.

We operate on a 52 -week or 53 -week year ending on the Friday nearest June 30. The first three quarters of fiscal 2016 and the first two quarters of fiscal 2015 included 13  weeks in each quarter. The third quarter of fiscal 2015 included 14 weeks.

Use of Estimates

The preparation of consolidated financial statements in accordance with U.S. GAAP requires us to make estimates, assumptions and judgments affecting the amounts reported and related disclosures. Estimates are based upon historical factors, current circumstances and the experience and judgment of our management. We evaluate our estimates and assumptions on an ongoing basis and may employ outside experts to assist us in making these evaluations. Changes in such estimates, based on more accurate information, or different assumptions or conditions, may affect amounts reported in future periods. Such estimates affect significant items, including revenue recognition, provision for doubtful accounts, inventory valuation, valuation allowances for deferred tax assets, uncertainties in income taxes, restructuring obligations, product warranty obligations, share-based awards, contingencies and useful lives of property, plant and equipment.

Reclassification

During the first quarter of fiscal 2016, we recorded a $1.2 million reclassification to increase long term unearned income and decrease current advance payments and unearned income as of July 3, 2015. This reclassification had no impact on our total assets, total liabilities, results of operations or cash flows.

During the second quarter of fiscal 2016, we recorded a $4.7 million reclassification to decrease both accounts receivable and current unearned income in our consolidated balance sheet as of July 3, 2015. This reclassification had no impact on our results of operations. In our consolidated statements of cash flow, the reclassification increased changes in accounts receivables and decreased changes in advance payments and unearned income by $4.7 million ; however, the net cash used in operating activities was not impacted by this reclassification. This reclassification was immaterial to the

previously issued financial statements; therefore, we revised our consolidated balance sheet for comparative purpose. The following table summarizes the effect of this reclassification on the previously filed consolidated balance sheet as of July 3, 2015:

Summary of Significant Accounting Policies

There have been no material changes in our significant accounting policies as of and for the first three quarters of fiscal 2016 , as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended July 3, 2015 .

Recently Issued Accounting Standards

In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-09, Improvements to Employee Share-Based Payment Accounting (Topics 718 ), which requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase more of an employee's shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. The guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2016 with early adoption permitted. We are evaluating the effect of the adoption of the standard will have on our condensed consolidated financial statements and related disclosures.

In February 2016, the FASB ASU 2016-02, Leases (Topics 842), which introduces the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. This standard will become effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The guidance is required to be adopted at the earliest period presented using a modified retrospective approach. We are evaluating the effect of the adoption of the standard will have on our condensed consolidated financial statements and related disclosures.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . This guidance retains the current accounting for classifying and measuring investments in debt securities and loans, but requires equity investments to be measured at fair value with subsequent changes recognized in net income, except for those accounted for under the equity method or requiring consolidation. The guidance also changes the accounting for investments without a readily determinable fair value and that do not qualify for the practical expedient to estimate fair value. A policy election can be made for these investments whereby estimated fair value may be measured at cost and adjusted in subsequent periods for any impairment or changes in observable prices of identical or similar investments. This ASU is effective for fiscal years beginning after December 15, 2017. We are currently evaluating the impact this guidance will have on our condensed consolidated financial statements and it will become effective for us at the beginning of our first quarter of fiscal 2019.

In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740) - Balance Sheet Classification of Deferred Taxes , which amends the existing guidance on income taxes to require the classification of all deferred tax

assets and liabilities as non-current on the balance sheet. The amendments are effective for financial statements issued for the annual periods beginning after December 15, 2016 and interim periods within those annual periods, and may be applied either prospectively or retrospectively. Early adoption is permitted. We are currently evaluating the effect of the adoption of the standard will have on our condensed consolidated financial statements and related disclosures.

In July 2015, the FASB issued ASU No. 2015-11 (Subtopic 330), Simplifying the Measurement of Inventory , which provides guidance to companies who account for inventory using either the first-in, first-out ("FIFO") or average cost methods. The guidance states that companies should measure inventory at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU is effective for fiscal years beginning after December 15, 2016. Early adoption is permitted. We are currently evaluating the effect of the adoption of the standard will have on our condensed consolidated financial statements and related disclosures.

In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30), Simplifying the Presentation of Debt Issuance Costs , which provides guidance on the balance sheet presentation for debt issuance costs and debt discounts and debt premiums. To simplify the presentation of debt issuance costs, the standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard is effective for us beginning in our fiscal year 2017. We are currently evaluating the effect of the adoption of the standard will have on our condensed consolidated financial statements and related disclosures.

In August 2014, FASB issued ASU No. 2014-15, Disclosure of Uncertainties About an Entity's Ability to Continue as a Going Concern , which provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. The guidance requires management to perform interim and annual assessments of an entity's ability to continue as a going concern. This standard is effective for annual reporting periods beginning after December 15, 2016, including interim periods during those annual periods. Early application is permitted. We are currently evaluating the effect of the adoption of the standard will have on our condensed consolidated financial statements and related disclosures.

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU is based on the principle that revenue is recognized 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. This 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 obtain or fulfill a contract. In July 2015, the FASB deferred the effective date of this ASU from December 15, 2016 to December 15, 2017, with early adoption permitted before annual periods beginning after December 15, 2016. Accordingly, the new standard is effective for us beginning in our fiscal year 2019. The principles may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. We are currently evaluating the transition methods and the effect that this ASU will have on our condensed consolidated financial statements and related disclosures.

Note 2. Net Loss Per Share of Common Stock

We compute net loss per share attributable to our common stockholders using the two-class method. Basic net loss per share is computed using the weighted average number of common shares and participating securities outstanding during the period. Our unvested restricted shares contain rights to receive non-forfeitable dividends and therefore are considered to be participating securities and would be included in the calculations of net income per basic and diluted common share. Undistributed losses are not allocated to unvested restricted shares due to the fact that the unvested restricted shares are not contractually obligated to share the losses of the company.

As we incurred a net loss for all periods presented, the effect of outstanding stock options, restricted stocks and units and performance shares and units were anti-dilutive, and therefore, were excluded from the diluted net loss per share calculations. The following table summarizes the potential shares of common stock that were excluded from the diluted net loss per share calculations:

Note 3. Balance Sheet Components

Accounts Receivable, net

Our net accounts receivable as of April 1, 2016 and July 3, 2015 was as follows :

We regularly require letters of credit from some customers and, from time to time, we discount these letters of credit issued by customers through various financial institutions. The discounting of letters of credit depends on many factors, including the willingness of financial institutions to discount the letters of credit and the cost of such arrangements. Under these arrangements, collection risk is fully transferred to the financial institutions. We record the financing charges on discounting these letters of credit as interest expense. Total customer letters of credit discounted and related interest expense were as follows:

Inventories

Our inventories as of April 1, 2016 and July 3, 2015 were as follows :

We recorded charges to adjust our inventory and customer service inventory to the lower of cost or market. These charges were primarily due to excess and obsolete inventory resulting from product transitioning and discontinuance. During the third quarter and first three quarters of fiscal 2016 and 2015 , such charges incurred were classified in cost of product sales as follows:

Property, Plant and Equipment, net

Our property, plant and equipment, net as of April 1, 2016 and July 3, 2015 were as follows:

Depreciation and amortization expense related to property, plant and equipment, including amortization of software developed for internal use, was as follows:

Accrued Warranties

We accrue for the estimated cost to repair or replace products under warranty at the time of sale. Changes in our warranty liability, which is included as a component of other accrued expenses in the condensed consolidated balance sheets, during the third quarter and first three quarters of fiscal 2016 and 2015 were as follows:

Note 4. Fair Value Measurements of Assets and Liabilities

We determine fair value as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants as of the measurement date. We maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value and establish a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows:

The carrying amounts, estimated fair values and valuation input levels of our assets and liabilities that are measured at fair value on a recurring basis as of April 1, 2016 and July 3, 2015 were as follows:

We classify items within Level 1 if quoted prices are available in active markets. Our Level 1 items mainly are money market funds. As of April 1, 2016 and July 3, 2015 , these money market funds were valued at $ 1.00  net asset value per share.

We classify items in Level 2 if the observable inputs to quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources are available with reasonable levels of price transparency. Our bank certificates of deposit and foreign exchange forward contracts are classified within Level 2. Foreign currency forward contracts are measured at fair value using observable foreign currency exchange rates. The assets and liabilities related to our foreign currency forward contracts were not material as of April 1, 2016 and July 3, 2015 . The changes in fair value related to our foreign currency forward contracts were recorded in cost of revenues on our statements of operations.

As of April 1, 2016 and July 3, 2015 , we did not have any assets or liabilities that were valued using Level 3 inputs.

Our policy is to recognize asset or liability transfers among Level 1, Level 2 and Level 3 as of the actual date of the events or change in circumstances that caused the transfer. During the first three quarters of fiscal 2016 and 2015 , we had no transfers between levels of the fair value hierarchy of our assets or liabilities measured at fair value.

Note 5. Credit Facility and Debt

On March 28, 2014, we entered into a Second Amended and Restated Loan Agreement with Silicon Valley Bank (the "SVB Credit Facility"). The SVB Credit Facility expires on September 26, 2016. In March 2016, we amended the SVB Credit Facility to reduce the maximum borrowing capacity from $40.0 million to $30.0 million , with no change to the $30.0 million sublimit that can be borrowed by our Singapore subsidiary and decrease the EBITDA covenant from $1.0 to a negative $5.5 million in order to remain in compliance with this covenant for our third quarter of fiscal 2016. Borrowings may be advanced under the SVB Credit Facility are at the lesser of $30.0 million or a borrowing base equal to a specified percentage of the value of eligible accounts receivable and U.S. unbilled accounts of the Company, subject to certain reserves and eligibility criteria. Our outstanding debt under the SVB Credit Facility was $9.0 million as of April 1, 2016 and July 3, 2015 . The SVB Credit Facility carries an interest rate computed at the daily prime rate as published in the Wall Street Journal plus a spread of 0.50% to 1.50% , with such spread determined based on our adjusted quick ratio. During the first three quarters of fiscal year 2016, the weighted average interest rate on our outstanding loan was 3.91% . As of April 1, 2016 , available credit under the SVB Credit Facility was $7.6 million reflecting the calculated borrowing base of $22.9 million less existing borrowings of $9.0 million and outstanding letters of credit of $6.3 million . The borrowing base was computed at 65% of eligible accounts receivable and 50% of eligible unbilled accounts receivable as of April 1, 2016 .

The SVB Credit Facility contains quarterly financial covenants including minimum adjusted quick ratio and minimum profitability (EBITDA) requirements. In the event our adjusted quick ratio falls below a certain level, cash received in our accounts with SVB may be directly applied to reduce outstanding obligations under the SVB Credit Facility. The SVB Credit Facility also imposes certain restrictions on our ability to dispose of assets, permit a change in control, merge or consolidate, make acquisitions, incur indebtedness, grant liens, make investments, make certain restricted payments and enter into transactions with affiliates under certain circumstances. Certain of our assets, including accounts receivable, inventory, and equipment, are pledged as collateral for the SVB Credit Facility. Upon an event of default, outstanding obligations would be immediately due and payable. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default at a per annum rate of interest equal to 2% above the applicable interest rate. As of April 1, 2016 , we were in compliance with the quarterly financial covenants, as amended, contained in the SVB Credit Facility.

In addition, we have an uncommitted short-term line of credit of $0.4 million from a bank in New Zealand to support the operations of our subsidiary located there. This line of credit provides for $0.3 million in short-term advances at various interest rates, all of which was available as of April 1, 2016 and July 3, 2015 . The line of credit also provides for the issuance of standby letters of credit and company credit cards, of which $0.1 million was outstanding as of April 1, 2016 . This facility may be terminated upon notice, is reviewed annually for renewal or modification, and is supported by a corporate guarantee.

Note 6. Restructuring Activities

The following table summarizes our restructuring related activities during the nine months ended April 1, 2016 :

As of April 1, 2016 , $2.7 million of the accrual balance is in short-term restructuring liabilities while $0.5 million is included in other long-term liabilities on the condensed consolidated balance sheets.

Fiscal 2015-2016 Plan

During the third quarter of fiscal 2015, with the intent to bring our operational cost structure in line with the changing dynamics of the microwave radio and telecommunications markets, we initiated a restructuring plan (the "Fiscal 2015-2016 Plan") to lower fixed overhead costs and operating expenses and to preserve cash flow. Activities under the Fiscal 2015-2016 Plan primarily include reductions in force across the Company, but primarily in operations outside the United States. The restructuring charges recorded during the third quarter and first three quarters of fiscal 2016 were $0.3 million in each period.

Fiscal 2014-2015 Plan

During the third quarter of fiscal 2014, in line with the decrease in revenue that we experienced and our reduced forecast for the immediate future, we initiated a restructuring plan (the "Fiscal 2014-2015 Plan") to reduce our operating costs, primarily in North America, Europe and Asia. Activities under the Fiscal 2014-2015 Plan primarily include reductions in force and additional facility downsizing of our Santa Clara, California headquarters. The restructuring charges recorded during the third quarter and first three quarters of fiscal 2016 were $0.2 million in each period.

Fiscal 2013-2014 Plan

During the fourth quarter of fiscal 2013, we initiated a restructuring plan (the "Fiscal 2013-2014 Plan") that was intended to reduce our operating expenses primarily in North America, Europe and Asia. Activities under the Fiscal 2013-2014 Plan included reductions in force and facility downsizing of our Santa Clara, California headquarters and certain international field offices. The restructuring charges recorded during the third quarter and first three quarters of fiscal 2016 were $0.3 million in each period.

Note 7. Stockholders' Equity

2007 Stock Equity Plan and Activities

We have one stock incentive plan for our employees and nonemployee directors, the 2007 Stock Equity Plan, as amended and restated effective November 13, 2015 (the "2007 Stock Plan"). As of April 1, 2016 , we have various incentive programs under the 2007 Stock Plan, including annual and long-term incentive programs ("AIP" or "LTIP") and a global equity program ("GEP"). The Company is authorized to issue up to 26.9 million shares of common stock under the 2007 Stock Plan.

During the first three quarters of fiscal 2016 , we awarded  1,831,158  market-based stock units and 2,293,647 restricted stock units associated with our fiscal 2016 LTIP under the 2007 Stock Plan. For the market-based stock units, the performance criteria are based on multiple target closing prices of the Company's common stock for the fiscal years ending 2016, 2017 and 2018. Once the shares are earned for fiscal years ending 2016 and 2017, they will be vested on the last day of fiscal 2018. For the shares earned for the fiscal year ending 2018, they will be vested on the date that the Compensation Committee certifies achievement of the performance metrics. Vesting of these shares is dependent on continuous employment with us through the date the performance metric is achieved.

During the first quarter of fiscal 2016 , we cancelled 803,210 performance stock units due to the performance criteria not being achieved. During the first three quarters of fiscal 2016 , we cancelled 65,062 performance stock units, 104,531 share of restricted stock unit, and options to purchase 1,649,094 shares of our common stock due to employee terminations. During the first three quarters of fiscal 2016 , options to purchase 242,538 shares of our common stock expired.

We issue new shares of our common stock to our employees upon the exercise of stock options, vesting of restricted stock awards and units or vesting of performance share awards and units. All awards that are cancelled prior to vesting or expire unexercised are returned to the approved pool of reserved shares under the 2007 Stock Plan and made available for future grants. Shares of our common stock remaining available for future issuance under the 2007 Stock Plan totaled 8,542,662 as of April 1, 2016 .

Share-Based Compensation

Total compensation expense for share-based awards included in our condensed consolidated statements of operations for the third quarter and first three quarters of fiscal 2016 and 2015 was as follows:

As of April 1, 2016 , there was $3.1 million of total unrecognized compensation expense related to unvested share-based awards granted under our 2007 Stock Plan. This expense is expected to be recognized over a weighted average period of 2.16  years.

The fair value of each option grant under our 2007 Stock Plan was estimated using the Black-Scholes option pricing model on the date of grant. A summary of the significant weighted average assumptions we used in the Black-Scholes valuation model is as follows:

The fair value of each market-based stock unit with market condition was estimated using a Monte-Carlo simulation model. A summary of the significant weighted average assumptions we used in the Monte Carlo simulation model is as follows:

The fair value of the market-based stock units with market condition criteria is expensed over the derived service period for each separate vesting tranche. If the derived service period is rendered, the total fair value of the award at the date of the grant is recognized as compensation expense even if the market condition is not achieved. No performance stock units were issued during the third quarter of 2016.

Note 8. Segment and Geographic Information

We operate in one reportable business segment: the design, manufacturing and sale of a range of wireless networking products, solutions and services. We conduct business globally and our sales and support activities are managed on a geographic basis. Our Chief Executive Officer is our Chief Operating Decision Maker (the "CODM").

We report revenue by region and country based on the location where our customers accept delivery of our products and services. Revenue by region for the third quarter and first three quarters of fiscal 2016 and 2015 were as follows:

Mobile Telephone Networks Group (MTN Group) accounted for more than 10% of our accounts receivable as of April 1, 2016 and July 3, 2015 . During the third quarter and first three quarters of fiscal 2016 and 2015, MTN Group accounted for more than 10% of our total revenue. We have entered into separate and distinct contracts with MTN Group, as well as separate arrangements with various MTN Group subsidiaries. The loss of all business from MTN Group could adversely affect our results of operations, cash flows and financial position.

Note 9. Divestiture

We sold our WiMAX business on September 2, 2011. In the third quarter of fiscal 2011, we began accounting for the WiMAX business as a discontinued operation and, therefore, the operating results of our WiMAX business were included in discontinued operations in our condensed consolidated financial statements for all periods presented. The income recognized in the first three quarters of fiscal 2016 was primarily due to recovery of certain WiMAX customer receivables that were previously written down. Summary results of operations for the WiMAX business were as follows:

Note 10. Income Taxes

Our effective tax rate varies from the U.S. federal statutory rate of 35% due to results of foreign operations that are subject to income taxes at different statutory rates and certain jurisdictions where we cannot recognize tax benefits on current losses. During interim periods, we accrue tax expenses for foreign jurisdictions that are anticipated to be profitable for fiscal 2016.

The determination of our provision for the first three quarters of fiscal 2016 and 2015 was based on our estimated annual effective tax rate adjusted for losses in certain jurisdictions for which no tax benefit can be recognized. The tax expense for the first three quarters of fiscal 2016 was primarily attributable to tax expense related to profitable foreign subsidiaries.

We have a number of years with open tax audits which vary from jurisdiction to jurisdiction. Our major tax jurisdictions include the U.S., Singapore and Nigeria. The earliest years that are open and subject to potential audits for these jurisdictions are as follows: U.S. - 2003; Singapore - 2006; and Nigeria - 2011.

We account for interest and penalties related to unrecognized tax benefits as part of our provision for federal, foreign and state income taxes. Such interest expense we accrued for was not material for the third quarter and first three quarters of fiscal 2016 and fiscal 2015.

Note 11. Commitments and Contingencies

Operating Lease Commitments

We lease office and manufacturing facilities under non-cancelable operating leases expiring at various dates through 2022. We lease approximately 129,000 square feet of office space in Santa Clara, California as our corporate headquarters. Beginning in the first quarter of fiscal 2015, approximately three-fourths of our Santa Clara headquarters building was vacated and made available for sublease. As of April 1, 2016 , future minimum lease payments for our headquarters totaled $10.8 million .

As of April 1, 2016 , our future minimum lease payments under all non-cancelable operating leases with an initial lease term in excess of one year were as follows:

These commitments do not contain any material rent escalations, rent holidays, contingent rent, rent concessions, leasehold improvement incentives or unusual provisions or conditions.

Rental expense for operating leases, including rentals on a month-to-month basis, was as follows:

Purchase Orders and Other Commitments

From time to time in the normal course of business we may enter into purchasing agreements with our suppliers that require us to accept delivery of, and remit full payment for, finished products that we have ordered, finished products that we requested be held as safety stock, and work in process started on our behalf, in the event we cancel or terminate the purchasing agreement. Because these agreements do not specify fixed or minimum quantities, do not specify minimum or variable price provisions, and do not specify the approximate timing of the transaction, and we have no present intention to cancel or terminate any of these agreements, we currently do not believe that we have any future liability under these agreements. As of April 1, 2016 , we had outstanding purchase obligations with our suppliers or contract manufacturers of $22.5 million . In addition, we had contractual obligations of approximately  $0.3 million  associated with a major service agreement as of  April 1, 2016 .

Financial Guarantees and Commercial Commitments

Guarantees issued by banks, insurance companies or other financial institutions are contingent commitments issued to guarantee our performance under borrowing arrangements, such as bank overdraft facilities, tax and customs obligations and similar transactions or to ensure our performance under customer or vendor contracts. The terms of the guarantees are generally equal to the remaining term of the related debt or other obligations and are generally limited to two years or less. As of April 1, 2016 , we had no guarantees applicable to our debt arrangements.

We have entered into commercial commitments in the normal course of business including surety bonds, standby letters of credit agreements and other arrangements with financial institutions primarily relating to the guarantee of future performance on certain contracts to provide products and services to customers. As of April 1, 2016 , we had commercial commitments of $20.0 million outstanding that were not recorded in our condensed consolidated balance sheets. We do not believe, based on historical experience and information currently available, that it is probable that any amounts will be required to be paid on the performance guarantees.

Indemnifications

Under the terms of substantially all of our license agreements, we have agreed to defend and pay any final judgment against our customers arising from claims against such customers that our software products infringe the intellectual property rights of a third party. As of April 1, 2016 , we have not received any notice that any customer is subject to an infringement claim arising from the use of our software products; we have not received any request to defend any customers from infringement claims arising from the use of our software products; and we have not paid any final judgment on behalf of any customer related to an infringement claim arising from the use of our software products. Because the outcome of infringement disputes is related to the specific facts of each case, and given the lack of previous or current indemnification claims, we cannot estimate the maximum amount of potential future payments, if any, related to our indemnification provisions. As of April 1, 2016 , we had not recorded any liabilities related to these indemnifications.

Legal Proceedings

From time to time, we may be involved in various legal claims and litigation that arise in the normal course of our operations. We are aggressively defending all current litigation matters. Although there can be no assurances and the outcome of these matters is not determinable, we currently believe that none of these claims or proceedings are likely to have a material adverse effect on our financial position. There are many uncertainties associated with any litigations and these matters or other third-party claims against us may cause us to incur costly litigation and/or substantial settlement charges. As a result, our business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from our estimates, if any.

We record accruals for our outstanding legal proceedings, investigations or claims when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. We evaluate, at least on a quarterly basis, developments in legal proceedings, investigations or claims that could affect the amount of any accrual, as well as any developments that would result in a loss contingency to become both probable and reasonably estimable. We have not recorded any accrual for loss contingencies associated with any such legal claims or litigation discussed above.

Contingent Liabilities

We record a loss contingency as a charge to operations when (i) it is probable that an asset has been impaired or a liability has been incurred at the date of the financial statements; and (ii) the amount of the loss can be reasonably estimated. Disclosure in the notes to the financial statements is required for loss contingencies that do not meet both those conditions if there is a reasonable possibility that a loss may have been incurred. Gain contingencies are not recorded until realized. We expense all legal costs incurred to resolve regulatory, legal and tax matters as incurred.

Periodically, we review the status of each significant matter to assess the potential financial exposure. If a potential loss is considered probable and the amount can be reasonably estimated, we reflect the estimated loss in our results of operations. Significant judgment is required to determine the probability that a liability has been incurred or an asset impaired and whether such loss is reasonably estimable. Further, estimates of this nature are highly subjective, and the final outcome of these matters could vary significantly from the amounts that have been included in our consolidated financial statements. As additional information becomes available, we reassess the potential liability related to our

pending claims and litigation and may revise estimates accordingly. Such revisions in the estimates of the potential liabilities could have a material impact on our results of operations and financial position.

Note 12. Subsequent Events

On April 7, 2016, our Board of Directors approved certain cost reduction initiatives that will result in annual cost savings between $6.0 million and $7.0 million . These initiatives will allow us to align our operating cost structure with current revenue levels due to the changing dynamics of the telecommunication market. These actions will impact various domestic and international locations and include a reduction in workforce of approximately 87 employees primarily in the services, sales and marketing, and general and administrative functions. We expect to incur total estimated restructuring charges of approximately $4.0 million related to employee severance, benefits and other related charges. We anticipate approximately 50% of the total estimated restructuring charges will be incurred in the fourth quarter of fiscal 2016 and the balance over the following three quarters. These cost reductions are expected to be substantially completed by March 31, 2017.

We filed a proxy statement on April 29, 2016 to obtain stockholders' approval to amend our Amended and Restated Certificate of Incorporation to effect a reverse stock split of our common stock whereby each 12 shares of common stock outstanding would be combined and converted into one share of common stock. The reverse stock split is being proposed to increase the market price of our common stock to satisfy the $1.00 minimum closing bid price required to avoid the delisting of our common stock from The Nasdaq Global Select Market. We expect this action to be completed in June 2016.

Overview of Business; Operating Environment and Key Factors Impacting Fiscal 2015 and 2016 Results

The following Management's Discussion and Analysis ("MD&A") is intended to help the reader understand our results of operations and financial condition. MD&A is provided as a supplement to, and should be read in conjunction with, our condensed consolidated financial statements and the accompanying notes. In the discussion below, our fiscal year ending July 1, 2016 is referred to as "fiscal 2016 " or " 2016 " and fiscal year ended July 3, 2015 is referred to as "fiscal 2015 " or " 2015 ".

We generate revenue by designing, developing, manufacturing and supporting a range of wireless networking products, solutions and services for mobile and fixed communications service providers, private network operators, government agencies, transportation and utility companies, public safety agencies and broadcast system operators across the globe. Our products include point-to-point digital microwave transmission systems designed for first/last mile access, middle mile/backhaul, and long distance trunking applications. We also provide network management software solutions to enable operators to deploy, monitor and manage our systems, third party equipment such as antennas, routers, and multiplexers, necessary to build and deploy a wireless transmission network, and a full suite of turnkey support services.

We work continuously to improve our established brands and to create new products that meet our customers' evolving needs and preferences. Our fundamental business goal is to generate superior returns for our stockholders over the long term. We believe that increases in revenue, operating profits and earnings per share are the key measures of financial performance for our business. However, within the industry there continues to be strong price competition for new business and periodic large customer consolidations that intensify competition in all regions.

Our strategic focus in fiscal 2016 is to continue to accelerate innovation and optimize our product portfolio, improve costs and operational efficiencies, grow our revenue and create a sustainable, profitable business model. To do this, we continue to examine our products, markets, facilities, development programs, and operational flows to ensure we

are focused on what we do well and what will differentiate us in the future. We will continue working to streamline management processes to attain the efficiency levels required by the markets in which we do business.

Although the general trend of increasing demand for bandwidth to support mobile networks applies in all markets, we expect to see quarter-to-quarter fluctuations within markets and with individual customers based on customers' past purchasing patterns. Seasonality is also a factor that impacts our business. Our fiscal third quarter revenue and orders have historically been lower than the revenue and orders in our second fiscal quarter because many of our customers utilize a significant portion of their capital budgets at the end of their fiscal years, which is typically the calendar year end and coincides with our second fiscal quarter. The majority of our customers begin a new fiscal year on January 1, and capital expenditures tend to be lower in an organization's first quarter than in its fourth quarter. We anticipate that this seasonality will continue. The seasonality between the second quarter and third quarter may be affected by a variety of additional factors, including changes in the global economy.

In line with industry trends, we expect to provide increased managed services, including network design, inventory management, final configuration and warehousing services, to certain customers in certain geographies. Our operating results may be impacted by providing these services to the extent that we may need to postpone the recognition of revenue and incur upfront and ongoing expenses that are not offset with additional revenue from product sales associated with these services until a future period.

Operations Review

The market for mobile backhaul continues to be our primary addressable market segment and, over the long term, the demand for increasing the backhaul capacity in our customers' networks continues to grow. In North America we supported long-term evolution ("LTE") deployments of our mobile operator customers, public safety network deployments for state and local governments, and private network implementations for utilities and other customers. Internationally, our business continued to rely on a combination of customers increasing their capacity to handle subscriber growth, the ongoing build-out of some large 3G deployments, and the emergence of early stage LTE deployments. Our position continues to be to support our customers for LTE readiness and ensure that our technology roadmap is well aligned with evolving market requirements. We continue to find that our strength in turnkey and after-sale support services is a differentiating factor that wins business for us and enables us to expand our business with existing customers in all markets. However, as disclosed above and in the "Risk Factors" section in Item 1A of our fiscal 2015 Annual Report on Form 10-K, a number of factors could prevent us from achieving our objectives, including ongoing pricing pressures attributable to competition and macroeconomic conditions in the geographic markets that we service.

Revenue

We manage our sales activities primarily on a geographic basis in North America and three international geographic regions: (1) Africa and Middle East, (2) Europe and Russia, and (3) Latin America and Asia Pacific. Revenue by region for the third quarter and first three quarters of fiscal 2016 and 2015 and the related changes were shown in the table below:

Our revenue in North America was down $4.8 million , or 15.0% , during the third quarter of fiscal 2016 compared with the same quarter of fiscal 2015 . North America revenue decreased primarily due to fewer orders from our wireless operator customers as they reached the end of their LTE network build cycle. In addition, we saw a small decrease in sales volume to government and utility markets. On a year-to-date basis, North America revenue decreased $20.5 million , or 17.9% , compared with the same period in fiscal 2015. The year-to-date decrease in North America was

mostly from the reductions in wireless operator purchases, along with smaller reductions in revenue from certain private network customers.

Our revenue in Africa and Middle East decreased $4.8 million , or 20.9% , for the third quarter of fiscal 2016 compared with the same quarter of fiscal 2015 . The decrease in revenue came from decreased sales volume to our private network customers in the Middle East and a small reduction across several customers in Africa in the quarter. On a year-to-date basis, Africa and Middle East revenue didn't change significantly from the same period in fiscal 2015.

Revenue in Europe and Russia decreased $3.9 million , or 47.6% , for the third quarter of fiscal 2016 compared with the same quarter of fiscal 2015 . The decrease was mostly due to one customer where we completed a large set of orders in the third quarter of fiscal 2015, which was not repeated in fiscal 2016. On a year-to-date basis, revenue in Europe and Russia was down $11.7 million , or 41.6% , from the same period in fiscal 2015. The decrease came from lower sales to our large customers in the region compared with the same periods in fiscal 2015. Both the unfavorable currency value changes on our US dollar based prices and the limited customer capital spendings in the region contributed to the lower business volume during fiscal 2016.

Revenue in Latin America and Asia Pacific decreased $0.9 million , or 7.7% , during the third quarter of fiscal 2016 compared with the same quarter in fiscal 2015 . The decrease was primarily due to fewer deliveries to customers in Latin America in the quarter, which was partially offset by increased sales in Asia Pacific compared with the same quarter of fiscal 2015. On a year-to-date basis, revenue in Latin America and Asia Pacific decreased $5.5 million , or 15.2% , from the same period in fiscal 2015, mostly due to lower product sales to several mid-size customers in Asia Pacific, partially offset by a large increase with one of our major customers in the region. The decrease was also attributable to a year-to-year reduction in sales to private network customers in Latin America.

Our revenue from product sales decreased $10.8 million , or 23.0% , for the third quarter of fiscal 2016 compared with the same quarter in fiscal 2015 . Product volumes were lower in all sectors, but the majority of the decrease was in North America and Europe. Our services revenue decreased by $3.6 million , or 12.9% , during the third quarter of fiscal 2016 compared with the same quarter of fiscal 2015 . Most of the reduction was with customers in the Middle East and Africa.

Our revenue from product sales decreased by $24.7 million , or 15.5% , for the first three quarters of fiscal 2016 compared with the same period in fiscal 2015. The decrease came primarily from weaker product sales in North America, Europe, Latin America and Asia Pacific, offset in part by stronger product sales in the Middle East and Africa. Our services revenue was down by $13.0 million , or 14.6% , during the first three quarters of fiscal 2016 compared with the same period of fiscal 2015, due to reduced service activities in Middle East and Africa, North America and Europe.

During the third quarter and first three quarters of fiscal 2016 and 2015 , MTN Group in Africa accounted for more than 10% of our total revenue. We have entered into separate and distinct contracts with MTN Group as well as separate arrangements with various MTN Group subsidiaries. The loss of all business from MTN Group could adversely affect our results of operations, cash flows and financial position.

Gross Margin

Gross margin for the third quarter and the first three quarters of fiscal 2016 decreased by $1.6 million , or 10.0% , and $10.2 million , or 16.5% , respectively, compared with the same periods in fiscal 2015 . On the quarter-to-date basis, the decrease came primarily from reduced margin contribution from lower revenue volume that exceeded improved profit margins on sales and reduced supply chain costs. On a year-to-date basis, the decrease was mostly due to lower margin contribution on lower revenue volume that exceeded reduced supply chain costs.

Gross margin as a percentage of revenue increased in the third quarter of fiscal 2016 compared with the same quarter of fiscal 2015 , primarily due to improved service margins and lower supply chain costs. Product margin as a percentage of product revenue decreased slightly from the prior year quarter primarily due to lower margins in our Middle East and Africa sectors. Service margin as a percentage of service revenue increased primarily due to more profitable service business in most sectors.

On a year-to-date basis, gross margin as a percentage of revenue decreased slightly primarily due to lower gross margin rates in services businesses in all sectors compared with the same period in fiscal 2015. Product margin as a percentage of product revenue increased over the same period in fiscal 2015 primarily due to improved product margins in North America, and reduced supply chain costs.
