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. Due to the volume of our international sales, especially in developing countries, we may be susceptible to a number of political, economic and geographic risks that could harm our business as outlined in "Item 1A. Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended July 1, 2016. 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 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 three and nine months ended March 31, 2017 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 1, 2016 .

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

We operate on a 52 -week or 53 -week year ending on the Friday closest to June 30. The first three quarters of fiscal 2017 and fiscal 2016 included 13  weeks in each quarter. Fiscal year 2017 will be comprised of 52 weeks and will end on June 30, 2017 .

Use of Estimates

The preparation of unaudited condensed 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 uncollectible receivables, inventory valuation, valuation allowances for deferred tax assets, uncertainties in income taxes, restructuring obligations, product warranty obligations, share-based awards, contingencies, recoverability of long-lived assets and useful lives of property, plant and equipment.

Reverse Stock Split

In June 2016, we effected a reverse stock split of all of the outstanding shares of our common stock at a ratio of 1-for-12 ("Reverse Stock Split"). The authorized shares of 300 million and par value per share of the common stock at $0.01 per share remain unchanged after the reverse stock split. All share and per-share data in our unaudited condensed consolidated financial statements and applicable disclosures have been retroactively adjusted to reflect this reverse stock split.

Summary of Significant Accounting Policies

There have been no material changes in our significant accounting policies as of and for the nine months ended March 31, 2017 , as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended July 1, 2016 .

Accounting Standards Adopted

In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-03, Interest - Imputation of Interest (Topic 835-30), Simplifying the Presentation of Debt Issuance Costs . 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. In August 2015, the FASB issued ASU No. 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements . This ASU includes an SEC staff announcement that the SEC staff would not object to an entity deferring and presenting the costs of securing a revolving line of credit as an asset, and amortizing the costs over the term of the line-of-credit arrangement, regardless of there are any outstanding borrowings on the line-of-credit arrangement. The subject of this ASU was not previously addressed by ASU No. 2015-03. We have adopted both accounting guidance during the first quarter of fiscal 2017 and applied its provisions retrospectively. The adoption of this standard had no material impact on our financial statements and related disclosures.

Accounting Standards Not Yet Adopted

In November 2016, the FASB issued ASU 2016-18 Statement of Cash Flows (Topic 230): Restricted Cash . The guidance addresses diversity in practice that exists in the classification and presentation of changes in restricted cash and require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents.   The guidance will be effective retrospectively for our fiscal year 2019. E arly adoption is permitted. We do not expect the adoption of this standard to have a material impact on our financial statements.

In October 2016, the FASB issued ASU 2016-16 (Topic 740), Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory , which requires that an entity recognizes the tax expense from the sale of intra-entity sales of assets, other than inventory, in the seller's tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminate in consolidation.  The guidance will be effective for our fiscal year 2019. E arly adoption is permitted. The ASU must be adopted using a modified retrospective method.  We are evaluating the effect the adoption of the standard will have on our financial statements and related disclosures. We do not expect the adoption of this standard to have a material impact on our financial statements.

In August 2016, the FASB issued ASU No. 2016-15 Statement of Cash Flows (Topic 230) , Clarification of Certain Cash Receipts and Cash Payments , which provides guidance on the presentation and classification of eight specific cash flow issues. Those issues are cash payment for debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instrument or other debt instrument with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; cash received from settlement of corporate-owned life insurance policies; distribution received from equity method investees; beneficial interest in securitization transactions; and classification of cash receipts and payments that have aspect of more than one class of cash flows. The guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2017 with early adoption permitted. We do not expect the adoption of this standard to have a material impact on our financial statements.

In May 2014, the FASB issued ASU No. 2014-09 (ASC Topic 606) Revenue from Contracts with Customers , which along with amendments issued in 2015 and 2016, will supersede nearly all current U.S. GAAP guidance on this topic and eliminate industry-specific guidance. The amendments are based on the principle that revenue should be recognized to depict the transfer of promised 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. Additional disclosures will also be required to enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. This accounting standard update, as amended, will be effective for us in the first quarter of fiscal year 2019. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized in retained earnings as of the date of adoption. We are in the early

stages of evaluating the provisions and transition alternatives of this standard and its impact on our business processes, business and accounting systems, and financial statements and related disclosures. Due to the complexity of the new standard and the nature of our contracts, the actual revenue recognition treatment required under the new standard may vary and will be dependent on contract-specific terms. We are continuing to evaluate the impact of this guidance and the transition alternatives on our financial statements.

In March 2016, the FASB issued ASU 2016-09, (Topic 718) Improvements to Employee Share-Based Payment Accounting , 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 do not expect the adoption of this standard to have a material impact on our financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 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 expect that most of our operating lease commitments will be subject to the new standard and recognized as right-of-use assets and operating lease liabilities upon the adoption of ASU 2016-02. We are evaluating the effect the adoption of the standard will have on our financial statements.

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 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 do not expect the adoption of this standard to have a material impact on our financial statements.

In July 2015, the FASB issued ASU No. 2015-11 (Topic 330), Simplifying the Measurement of Inventory , which provides guidance to companies who account for inventory using either the first-in, first-out 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 evaluating the effect the adoption of the standard will have on our financial statements.

Note 2. Net (Loss) Income Per Share of Common Stock

Net (loss) income per share is computed using the two-class method, by dividing net (loss) income attributable to us by the weighted-average number of shares of our outstanding common stock. Our restricted shares contain rights to receive non-forfeitable dividends and therefore are considered to be participating securities and 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 our losses. The impact on earnings per share of the participating securities under the two-class method is immaterial.

The following table presents the computation of basic and diluted net income (loss) per share attributable to the common stockholders:

The following table summarizes the weighted-average equity awards that were excluded from the diluted net (loss) income per share calculations:

Note 3. Balance Sheet Components

Accounts Receivable, net

Our net accounts receivable were as follows:

Inventories

Our inventories 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 or discontinuance. During the three and nine months ended March 31, 2017 and April 1, 2016 , we recorded a recovery of $0.4 million related to previously reserved inventory due to sell through. Recovery from sell through or charges incurred were classified in cost of product sales as follows:

Property, Plant and Equipment, net

Our property, plant and equipment, net 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 Expenses

Our accrued expenses are summarized below:

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 accrued expenses in the unaudited condensed consolidated balance sheets were as follows:

Advanced payments and Unearned Income

Our advanced payments and unearned income are summarized below:

Note 4. Fair Value Measurements of Assets and Liabilities

Fair value is defined 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 March 31, 2017 and July 1, 2016 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 March 31, 2017 and July 1, 2016 , 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 changes in fair value related to our foreign currency forward contracts were recorded in cost of revenues on our unaudited condensed consolidated statements of operations.

As of March 31, 2017 and July 1, 2016 , we did not have any recurring assets or liabilities that were valued using significant unobservable 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 nine months of fiscal 2017 and 2016 , 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 June 30, 2018. The SVB Credit Facility provides for a committed amount of up to $30.0 million , with a $30.0 million sublimit that can be borrowed by our Singapore subsidiary. Borrowings may be advanced under the SVB Credit Facility 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. The SVB Credit Facility can also be utilized to issue letters of credit with a $12.0 million sublimit. If the SVB Credit Facility is terminated by us in certain circumstances prior to its expiration, we are subject to an early termination fee equal to 1% of the revolving line.

Our outstanding debt under the SVB Credit Facility was $8.0 million and $9.0 million as of March 31, 2017 and July 1, 2016 , respectively. 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 nine months of fiscal year 2017, the weighted average interest rate on our outstanding loan was 4.10% . As of March 31, 2017 , available credit under the SVB Credit Facility was $4.8 million reflecting the calculated borrowing base of $18.1 million less existing borrowings of $8.0 million and outstanding letters of credit of $5.3 million .

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 March 31, 2017 , we were in compliance with the quarterly financial covenants, as amended, contained in the SVB Credit Facility. However, as we have historically amended the agreement to revise financial covenants and the fact that the SVB Credit Facility contains subjective acceleration clauses that could be triggered by the lender, the $8.0 million and $9.0 million borrowing were classified as a current liability as of March 31, 2017 and July 1, 2016 , respectively.

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 March 31, 2017 and July 1, 2016 . 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 March 31, 2017 . 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 first nine months of fiscal 2017 :

In June 2016, we entered into a lease termination agreement to end our headquarters lease in Santa Clara, California and in September 2016 we vacated the building. Under the lease termination agreement, we agreed to pay a termination fee of $1.9 million payable over 14 months . The termination fee was included in the restructuring liabilities as of March 31, 2017 under the Fiscal 2014-2015 Plan and the Fiscal 2013-2014 Plan.

As of March 31, 2017 , $1.7 million of the accrual balance was in short-term restructuring liabilities while $0.2 million was included in other long-term liabilities on the unaudited condensed consolidated balance sheets.

Fiscal 2016-2017 Plan

During the fourth quarter of fiscal 2016, we initiated a restructuring plan (the "Fiscal 2016-2017 Plan") to streamline our operations and align expenses with current revenue levels. Activities under the Fiscal 2016-2017 Plan primarily include reductions in workforce in marketing, selling and general and administrative functions. We expect to complete the remaining restructuring activities under the Fiscal 2016-2017 Plan by the end of fiscal 2017. Payments related to the accrued restructuring liability balance for this plan will be paid through fiscal 2018.

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 workforce across the Company, but primarily in operations outside the United States. We substantially completed the restructuring activities under the Fiscal 2015-2016 Plan as of July 1, 2016. Payments related to the accrued restructuring liability balance for this plan will be paid through fiscal 2020.

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 workforce and additional facility downsizing of our Santa Clara, California headquarters. We substantially completed the restructuring activities under the Fiscal 2014-2015 Plan as of July 1, 2016. Payments related to the accrued restructuring liability balance for this plan will be paid through fiscal 2018.

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 workforce and facility downsizing of our Santa Clara, California headquarters and certain international field offices. We substantially completed the restructuring activities under the Fiscal 2013-2014 Plan as of June 27, 2014. Payments related to the accrued restructuring liability balance for this plan will be paid through fiscal 2018.

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"). During the nine months ended March 31, 2017 , we awarded  72,941  performance stock units, 50,000 market-based stock units and 237,874 restricted stock units associated with our fiscal 2017 Long-Term Incentive Plan under the 2007 Stock Plan. For the performance share units, the performance criteria is ending the fiscal year 2017 with positive adjusted earnings before interest, taxes, depreciation and amortization . Once the performance share units are earned, they will be vested three years after the grant date. For the market-based stock units , the performance goal is based on the Company's common stock price at the end of calendar year 2018. The award units will be vested on the date that the Compensation Committee certifies achievement of the performance measure.

During the nine months ended March 31, 2017 , we cancelled 7,219 market-based stock units, 14,277 restricted stock units, 983 shares of stock appreciation rights, and options to purchase 37,999 shares of our common stock due to employee terminations. In the same period, we cancelled 48,626 market-based stock units due to the non-achievement of specified market conditions and options to purchase 34,826 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 268,191 as of March 31, 2017 .

On September 6, 2016, our Board of Directors (the "Board") authorized and declared a dividend distribution of one right (a "Right") for each outstanding share of our common stock, par value $0.01 per share (the "Common Shares"), to our stockholders of record as of the close of business on September 16, 2016. Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Participating Preferred Stock, par value $0.01 per share (the "Preferred Shares"), of the Company at an exercise price of $35.00 (the "Exercise Price") per one one-thousandth of a Preferred Share, subject to adjustment. Until the rights become exercisable, they will not be evidenced

by separate certificates and will trade automatically with shares of the Company's common stock. The Rights have a de minimis fair value. The complete terms of the Rights are set forth in a Tax Benefit Preservation Plan (the "Plan"), effective as of September 6, 2016, between the Company and Computershare Inc., as rights agent. By adopting the Plan, we are helping to preserve the value of certain deferred tax benefits, including those generated by net operating losses (collectively, the "Tax Benefits"), which could be lost in the event of an "ownership change" as defined under Section 382 of the Internal Revenue Code of 1986, as amended. The Plan reduces the likelihood that changes in our investor base have the unintended effect of limiting our use of the Tax Benefits.

Also, on September 6, 2016, our Board of Directors adopted certain amendments to our Amended and Restated Certificate of Incorporation, as amended (the "Charter Amendments"). The Charter Amendments are designed to preserve the Tax Benefits by restricting certain transfers of our common stock.

Both the Plan and the Charter Amendments were approved at our 2016 annual meeting of stockholders on November 16, 2016. No actions were taken under the Plan as of March 31, 2017 .

Share-Based Compensation

Total compensation expense for share-based awards included in our unaudited condensed consolidated statements of operations for the three and nine months ended March 31, 2017 and April 1, 2016 was as follows:

As of March 31, 2017 , there was $0.2 million of total unrecognized compensation expense related to nonvested stock options granted under our 2007 Stock Plan. This expense is expected to be recognized over a weighted average period of 1.3  years. As of March 31, 2017 , there was $3.8 million of total unrecognized compensation expense related to nonvested stock awards and units granted under our 2007 Stock Plan. This expense is expected to be recognized over a weighted average period of 1.9  years.

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.

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 three and nine months ended March 31, 2017 and April 1, 2016 were as follows:

Mobile Telephone Networks Group (MTN Group) and Bharti Airtel (Airtel) accounted for 18% and 15% , respectively, of our accounts receivable as of March 31, 2017 . MTN Group and Motorola Solutions, Inc. (Motorola) accounted for 22% and 11% , respectively, of our accounts receivable as of  July 1, 2016 . During the three and nine months ended March 31, 2017 , MTN Group accounted for 19% and 13% , respectively, of our total revenue. During the three and nine months ended April 1, 2016 , MTN Group accounted for 20% and 18% , respectively, of our total revenue. We have entered into separate and distinct contracts with MTN Group, Motorola and Airtel, as well as separate arrangements with their various subsidiaries. The loss of all business from MTN Group, Motorola, Airtel, or any other significant customers, could adversely affect our results of operations, cash flows and financial position.

Note 9. Divestiture

We sold our WiMAX business on September 2, 2011 and began accounting for the WiMAX business as a discontinued operation. The operating results of our WiMAX business were included in discontinued operations in our unaudited condensed consolidated financial statements for all periods presented. The income recognized in the first nine months of fiscal 2016 of $0.5 million , net of income taxes, was primarily due to recovery of certain WiMAX customer receivables that were previously written down. No income was recognized in respect of the WiMAX business in the first nine months of fiscal 2017.

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, certain jurisdictions where we cannot recognize tax benefits on current losses and tax benefit from a foreign tax refund. During interim periods, we accrue tax expenses for jurisdictions that are anticipated to be profitable for fiscal 2017.

The determination of our provision for the first nine months of fiscal 2017 and 2016 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 nine months of fiscal 2017 and 2016 were primarily attributable to tax expense related to profitable subsidiaries.

During the fiscal year 2014, we received an assessment letter from the Inland Revenue Authority of Singapore ("IRAS") related to deductions claimed in prior years and made a payment of $13.2 million related to tax years 2007 through 2010, reflecting all the taxes incrementally assessed by IRAS. Since the initial assessment, we continue to pursue remedies to challenge this assessment. During the first quarter of fiscal 2017, we received an initial refund of $3.7 million from IRAS which was recorded as a discrete tax benefit during the quarter. We will continue our discussion with IRAS to resolve the remaining tax positions. We believe that we have adequately provided for any reasonably foreseeable outcomes related to our tax audits.

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 was not material for the three and nine months ended March 31, 2017 and April 1, 2016 .

Note 11. Commitments and Contingencies

Operating Lease Commitments

We lease office and manufacturing facilities under non-cancelable operating leases expiring at various dates through 2024. We lease approximately 19,000 square feet of office space in Milpitas, California with a term of 60 months as our corporate headquarters. In June 2016, we entered into a lease termination agreement for our previous headquarters lease in Santa Clara, California and the termination fees are included in the restructuring liabilities in the unaudited condensed consolidated balance sheets.

As of March 31, 2017 , 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. We sublease a portion of our facilities to third parties and the total minimum rents to be received in the future under our non-cancelable subleases were  $0.1 million  as of March 31, 2017 . The future minimum lease payments are not reduced by the minimum sublease rents.

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 March 31, 2017 , we had outstanding purchase obligations with our suppliers or contract manufacturers of $21.7 million . In addition, we had contractual obligations of approximately  $1.4 million associated with software licenses as of March 31, 2017 .

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 March 31, 2017 , 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 March 31, 2017 , we had commercial commitments of $33.8 million outstanding that were not recorded in our unaudited condensed consolidated balance sheets. During the second fiscal quarter, we recorded a payout in cost of revenues of $0.4 million on the performance guarantees to a contractor in the Middle East region. We believe the customer improperly drew on the performance bond and intend to pursue all remedies available to recover the payment. We do not believe, based on historical experience and information currently available, that it is probable that any significant amounts will be required to be paid on the performance guarantees in the future.

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 March 31, 2017 , 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 March 31, 2017 , we had not recorded any liabilities related to these indemnifications.

Legal Proceedings

We are subject from time to time to disputes with customers concerning our products and services. In May 2016, we received notification of a claim for $1.0 million in damages from a customer in Austria alleging that certain of our products were defective. We are continuing to investigate this claim, and at this time an estimate of the reasonably possible loss or range of loss cannot be made. We believe that we have numerous contractual and legal defenses to these disputes, and we intend to dispute them vigorously.

In August 2016, we received correspondence from a customer in Africa demanding that certain inventory be repurchased under the terms of an inventory management agreement that we believed had expired. We settled this matter for $0.2 million .

From time to time, we may be involved in various other 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 currently not determinable, we currently believe that none of these claims or proceedings are likely to have a material adverse effect on our financial position. We expect to defend each of these disputes vigorously. There are many uncertainties associated with any litigations and these actions 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 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 unaudited condensed consolidated financial statements; and (ii) the amount of the loss can be reasonably estimated. Disclosure in the notes to the unaudited condensed consolidated 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 unaudited condensed 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 Event

In April 2017, we recovered a deposit previously written off of $0.4 million for Canada's non-Resident Goods and Services Tax/Harmonized Tax. The deposit was made to the Canadian tax agency in 2007. The refund will be recorded in our financial results for the fourth quarter of fiscal year 2017.

Overview of Business; Operating Environment and Key Factors Impacting Fiscal 2016 and 2017 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 unaudited condensed consolidated financial statements and the accompanying notes. In the discussion below, our fiscal year ending June 30, 2017 is referred to as "fiscal 2017 " or " 2017 " and our fiscal year ended July 1, 2016 is referred to as "fiscal 2016 " or " 2016 ".

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, federal, state and local government agencies, transportation, energy and utility companies, public safety agencies and broadcast network operators around the world. 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, optical transmission equipment and other equipment necessary to build and deploy a complete telecommunications transmission network. We provide a full suite of professional services for planning, deployment, operations and maintenance of our customers' networks.

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 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.

We continue to explore strategic alternatives to improve the market position and profitability of our product offerings in the marketplace, generate additional liquidity and enhance our valuation. We expect to pursue our goals during the next twelve months principally through organic growth and through other strategic alternatives. Some of these alternatives have included, and could continue to include, selective acquisitions, divestitures and the sale of assets. We have also provided, and may from time to time in the future provide, information to interested parties.

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. In international markets, 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 international business was adversely affected in fiscal 2016 by constrained availability of U.S. dollars in countries with economies highly dependent on resource exports, particularly oil. This condition limited capital spending and slowed payments from customers in those locations. Those conditions are continuing in fiscal 2017. 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 2016 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 the Middle East, (2) Europe and Russia, and (3) Latin America and Asia Pacific. Revenue by region for the three and nine months ended March 31, 2017 and April 1, 2016 and the related changes were shown in the table below:

Our revenue in North America increased $2.0 million , or 7.5% , during the third quarter of fiscal 2017 compared with the same quarter of fiscal 2016 . North America revenue increased primarily due to an increase in revenue from private network projects. Revenue from mobile operators was flat relative to the third quarter of fiscal 2016. On a year-to-date basis, North America revenue increased $2.9 million , or 3.1% , compared with the same period in fiscal 2016 . The year-to-date increase in North America was from private network customers, offset by a decrease in revenue from mobile operators.

Our revenue in Africa and the Middle East decreased $0.8 million , or 4.6% , for the third quarter of fiscal 2017 compared with the same quarter of fiscal 2016 . The decrease in revenue was primarily due to lower sales volume to our large operator customers in Africa, including the MTN Group. On a year-to-date basis, Africa and the Middle East revenue decreased $20.7 million , or 29.9% , compared with the same period in fiscal 2016 . The year-to-date decrease in the region was also from lower sales to mobile operator customers in Africa and a decrease in revenue from private networks in the Middle East.

Revenue in Europe and Russia decreased $0.4 million , or 8.5% , for the third quarter of fiscal 2017 compared with the same quarter of fiscal 2016 . The decrease was primarily due to lower sales to some of our large mobile operator customers in the region, offset in part by an increase in sales to private network customers. On a year-to-date basis, revenue in Europe and Russia was down $5.1 million , or 31.1% , from the same period in fiscal 2016. The decrease came from lower sales to our large customers in the region compared with the same periods in fiscal 2016.

Revenue in Latin America and Asia Pacific decreased $2.6 million , or 24.1% , during the third quarter of fiscal 2017 compared with the same quarter in fiscal 2016 . The decrease was primarily due to decreased deliveries to our larger customers in Latin America. On a year-to-date basis, revenue in Latin America and Asia Pacific decreased $2.1 million , or 6.8% , from the same period in fiscal 2016 for the same reasons.

Our revenue from product sales increased $2.9 million , or 7.9% , for the third quarter of fiscal 2017 compared with the same quarter in fiscal 2016 . Product volumes were $4.5 million higher in North America, Africa and the Middle East, overcoming a $1.6 million decrease in other regions. Our services revenue was down by $4.6 million , or 19.1% , during the third quarter of fiscal 2017 compared with the same quarter of fiscal 2016 , due to reduced service activities in all regions.

Our revenue from product sales decreased by $14.8 million , or 11.0% , for the first nine months of fiscal 2017 compared with the same period in fiscal 2016 . The decrease came primarily from $19.8 million less product sales in Africa and the Middle East, Latin America and Asia, and Europe, offset in part by $5.0 million stronger sales in North America . Our services revenue was down by $10.2 million , or 13.4% , during the first nine months of fiscal 2017 compared with the same period of fiscal 2016 , due to reduced service activities in all regions.
