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 June 30, 2017 . 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 six months ended December 29, 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 June 30, 2017 .

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. Certain amounts in the consolidated financial statements of the prior period have been reclassified to conform to the presentation for the current period.

We operate on a 52 -week or 53 -week year ending on the Friday closest to June 30. The first two quarters of fiscal 2018 and fiscal 2017 included 13  weeks in each quarter. Fiscal year 2018 will be comprised of 52 weeks and will end on June 29, 2018 .

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.

Summary of Significant Accounting Policies

There have been no material changes in our significant accounting policies as of and for the six months ended December 29, 2017 , as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended June 30, 2017 .

Accounting Standards Adopted

In October 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-16 (Topic 740), Accounting for Income Taxes: Intra-Entity 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. We adopted this update during the first quarter of fiscal 2018. The adoption had no material impact on our unaudited condensed consolidated financial statements.

In July 2015, the FASB issued ASU 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. We adopted this update prospectively during the first quarter of fiscal 2018. The adoption had no material impact on our unaudited condensed consolidated financial statements.

Accounting Standards Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09 (ASC Topic 606), Revenue from Contracts with Customers with amendments issued in 2015 and 2016. This standard update will supersede nearly all current U.S. GAAP guidance on this topic and eliminate industry-specific guidance. Revenue recognition will 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. 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 on schedule in establishing new accounting policies, implementing systems and processes (including more extensive use of estimates), and internal controls necessary to support the requirements of the new standard. We have completed our preliminary assessment of the financial statement impact of the new standard and will continue to update that assessment as more information becomes available. We expect the timing of revenue recognition to change in certain areas, including our services segment's installation revenue, which upon adoption will be recognized as revenue and costs over a period of time. The performance obligations of certain arrangements are expected to be satisfied at the time of title transfer and risk of loss to the customer which is generally upon shipment, rather than at customer acceptance. Additionally, the analysis of our contracts under the new revenue recognition standard supports the recognition of revenue over time under the cost-to-cost method for some of our contracts, which is consistent with our current revenue recognition model. Revenue on these contracts will continue to be recognized over time because of the continuous transfer of control to the customer. Under the new standard, the cost-to-cost measure of progress continues to best depict the transfer of control of assets to the customer, which occurs as we incur costs. In addition, the number of our performance obligations within our financial accounting and reporting model under the existing standard is not expected to be materially different under the new standard. This preliminary assessment is based on the types and number of revenue arrangements currently in place. The exact impact of the new standard will be dependent on facts and circumstances at adoption and could vary from quarter to quarter.

We currently expense sales commissions as incurred, and the requirement in the new standard is to capitalize certain in-scope sales commissions. This requirement is being evaluated to determine its potential impact on our financial statements in the year of adoption. We expect to adopt the new standard on a modified retrospective basis in the first quarter of fiscal 2019. We are continuing to assess all potential impacts of the guidance on our unaudited condensed consolidated financial statements and given normal ongoing business dynamics, preliminary conclusions are subject to change.

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 unaudited condensed consolidated 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 unaudited condensed consolidated financial statements.

Note 2. Net Income Per Share of Common Stock

Net income per share is computed using the two-class method, by dividing net income attributable to us by the weighted-average number of shares of our outstanding common stock and participating securities outstanding. 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 as 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 per share attributable to our common stockholders:

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

Note 3. Balance Sheet Components

Cash, Cash Equivalents and Restricted Cash

The following table provides a summary of our cash, cash equivalents and restricted cash:

Accounts Receivable, net

Our net accounts receivable were as follows:

Inventories

Our inventories were as follows:

We record recovery or charges to adjust our inventory and customer service inventory due to excess and obsolete inventory resulting from lower sales forecasts, product transitioning or discontinuance. During the three and six months ended December 29, 2017 , we recorded a net recovery of $0.1 million and $0.1 million , respectively, related to previously reserved inventory due to sell through. During the three and six months ended December 30, 2016 , we recorded a net write down charge of $0.1 million and $0.6 million , respectively. Such recovery or charges during the three and six months ended December 29, 2017 and December 30, 2016 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 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 December 29, 2017 and June 30, 2017 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 December 29, 2017 and June 30, 2017 , 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 December 29, 2017 and June 30, 2017 , 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 six months of fiscal 2018 and 2017 , 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. In September 2017, the SVB Credit Facility was amended to allow up to 30% of our Singapore subsidiary's accounts receivable to be included in the calculation of the borrowing base and the inclusion of the accounts receivable of certain high credit quality customers that are aged 90 to 120 days to be included in the calculation of the borrowing base.

Our outstanding debt under the SVB Credit Facility was $9.0 million as of December 29, 2017 and June 30, 2017 . 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 six months of fiscal year 2018, the weighted average interest rate on our outstanding loan was 4.79% . As of December 29, 2017 , available credit under the SVB Credit Facility was $11.7 million reflecting the calculated borrowing base of $23.3 million less existing borrowings of $9.0 million and outstanding letters of credit of $2.6 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 December 29, 2017 , 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 December 29, 2017 and June 30, 2017 . 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 December 29, 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 six months of fiscal 2018 :

As of December 29, 2017 , $0.3 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. In January 2018, we reached an agreement with a certain foreign government which allowed us to reduce our estimated payments relating to the fiscal 2014-2015 restructuring plan by $0.3 million . We recorded this reduction in the second quarter of fiscal 2018.

We have completed the restructuring activities under each of the plans referenced in the table above. Remaining payments for these plans will be paid through fiscal year 2020.

Note 7. Equity

As of  December 29, 2017 , we had 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 first six months of fiscal 2018 , we issued 524 shares of common stock under the Employee Stock Purchase Plan (ESPP), and 191 shares of common stock for options exercised.

Total compensation expense for share-based awards included in our unaudited condensed consolidated statements of operations was as follows:

As of December 29, 2017 , there was $0.1 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 0.59  years. As of December 29, 2017 , there was $2.5 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 1.21  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 six months ended December 29, 2017 and December 30, 2016 was as follows:

During the three and six months ended December 29, 2017 , Mobile Telephone Networks Group (MTN Group) accounted 11% and 13% , respectively, of our total revenue. During the three and six months ended December 30, 2016 , MTN Group accounted for 12% and 11% , respectively, of our total revenue. Motorola Solutions, Inc. (Motorola) and MTN Group and T-Mobile accounted for 16% , 11% and 11% , respectively, of our accounts receivable as of December 29, 2017 . MTN Group also accounted for 26% of our accounts receivable as of  June 30, 2017 . We have entered into separate and distinct contracts with MTN Group and Motorola, as well as separate arrangements with their various subsidiaries. The loss of all business from MTN Group, Motorola, or any other significant customers, could adversely affect our results of operations, cash flows and financial position.

Note 9. Income Taxes

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act ("Tax Act"). The Tax Act makes broad and complex changes to the U.S. tax code that will affect our fiscal year ending June 29, 2018, including, but not limited to, (1) reducing the U.S. federal corporate tax rate, (2) requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years, and (3) elimination of the corporate Alternative Minimum Tax ("AMT"). The Tax Act reduces the federal corporate tax rate to 21.0% in the fiscal year ending June 29, 2018. Section 15 of the Internal Revenue Code stipulates that our fiscal year ending June 29, 2018 will have a blended corporate tax rate of 28.1% , which is based on the applicable tax rates before and after the Tax Act and the number of days in the year.

Our effective tax rate varies from the U.S. federal statutory rate of 28.1% 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, tax benefit from a foreign tax refund and release of valuation allowance. During interim periods, we accrue tax expenses for jurisdictions that are anticipated to be profitable for fiscal 2018.

The determination of our tax benefit for the first six months of fiscal 2018 and 2017 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 benefit for the first six months of fiscal 2018 was primarily attributable to the foreign tax refunds received from the Inland Revenue Authority of Singapore ("IRAS") and release of valuation allowance related to the refundable AMT credit as provided under the Tax Act, offset by tax expense related to profitable subsidiaries. The tax benefit for the first six months of fiscal 2017 was

primarily attributable to the foreign tax refund received from the IRAS, offset by the tax expense related to profitable subsidiaries.

During the fiscal year 2014, we received an assessment letter from 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 continued to challenge this assessment. During the first quarter of fiscal 2017, we received an initial refund of $3.7 million from IRAS. During the first quarter of fiscal 2018, we received an additional refund of  $1.3 million  from IRAS which represents a final settlement. These refunds were recorded as a discrete tax benefit during the quarter the respective payment was received. During the second quarter of fiscal 2018, we recorded a valuation allowance release of $3.3 million related to refundable AMT credit under the Tax Act as a discrete benefit and recorded as a long-term receivable in our Other Assets in the unaudited condensed consolidated balance sheet. Under the Tax Act, any carryforward AMT tax credits can be refunded if not fully utilized by fiscal year 2022. We expect to receive the refund of this tax benefit starting in our fiscal year 2020.

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, Nigeria and the Ivory Coast. The earliest years that are open and subject to potential audits for these jurisdictions are as follows: U.S. - 2003; Singapore - 2011; Nigeria - 2011, and Ivory Coast - 2016.

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 six months ended December 29, 2017 and December 30, 2016 .

The SEC staff issued Staff Accounting Bulletin ("SAB") No. 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company's accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

In connection with our initial analysis of the impact of the Tax Act, we have recorded a discrete net tax benefit of $3.3 million in the period ended December 29, 2017. This net benefit relates to a valuation allowance release of refundable AMT credit. For various reasons that are discussed more fully below, we have not fully completed our accounting for the income tax effects of certain elements of the Tax Act. If we were able to make reasonable estimates of the effects of elements for which our analysis is not yet complete, we recorded provisional adjustments. If we were not yet able to make reasonable estimates of the impact of certain elements, we have not recorded any adjustments related to those elements and have continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect before the Tax Act.

Our accounting for the following elements of the Tax Act is incomplete. However, we were able to make reasonable estimates of certain effects and, therefore, recorded provisional adjustments as follows:

Reduction of U.S. Federal Corporate Tax Rate: The Tax Act reduces the corporate tax rate to 21.0% , effective January 1, 2018. For certain deferred tax assets and deferred tax liabilities, we have recorded a provisional decrease of $53.8 million , respectively, with a corresponding net adjustment to valuation allowance of $53.8 million for the period ended December 29, 2017. While we are able to make a reasonable estimate of the impact of the reduction in corporate rate, it may be affected by other analyses related to the Tax Act, including, but not limited to, our calculation of deemed repatriation of deferred foreign income and the state tax effect of adjustments made to federal temporary differences.

Deemed Repatriation Transition Tax: The Deemed Repatriation Transition Tax ("Transition Tax") is a tax on previously untaxed accumulated and current earnings and profits ("E&P") of certain foreign subsidiaries. To determine the amount of the Transition Tax, we must determine, in addition to other factors, the amount of post-1986 E&P of the relevant subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. We are able to make a reasonable estimate of the Transition Tax and currently do not believe we will be charged this tax, due to preliminary calculations of net negative E&P for our foreign subsidiaries subjected to this tax. However, we are continuing to gather additional information to more precisely compute the amount of the Transition Tax.

Our accounting for the following elements of the Tax Act is incomplete, and we were not yet able to make reasonable estimates of the effects. Therefore, no provisional adjustments were recorded.

Global Intangible Low Taxed Income ("GILTI"): The Tax Act creates a new requirement that certain income (i.e., GILTI) earned by controlled foreign corporations ("CFCs") must be included currently in the gross income of the CFCs' U.S. shareholder. GILTI is the excess of the shareholder's "net CFC tested income" over the net deemed tangible income return, which is currently defined as the excess of, (1) 10.0% of the aggregate of the U.S. shareholder's pro-rata share of the qualified business asset investment of each CFC with respect to which it is a U.S. shareholder, (2) the amount of certain interest expense taken into account in the determination of net CFC-tested income.

Because of the complexity of the new GILTI tax rules, we are continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, we are allowed to make an accounting policy choice of either, (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the "period cost method") or, (2) factoring such amounts into a company's measurement of its deferred taxed (the "deferred method"). Our selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine whether we expect to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Because whether we expect to have future U.S. inclusions in taxable income related to GILTI depends on not only our current structure and estimated future results of global operations but also our intent and ability to modify our structure and/or our business, we are not yet able to reasonably estimate the effect of this provision of the Tax Act. Therefore, we have not made any adjustments related to the potential GILTI tax in our financial statements and have not made a policy decision regarding whether to record deferred taxes on GILTI.

Valuation Allowances: The company must assess whether valuation allowances assessments are affected by various aspects of the Tax Act (e.g., deemed repatriation of deferred foreign income, GILTI inclusions, new categories of FTCs, AMT repeal). During the second quarter of fiscal 2018, we recorded a valuation allowance release of $3.3 million related to refundable AMT credit under the Tax Act as a discrete benefit. Under the Tax Act, any carryforward AMT tax credits can be refunded if not fully utilized by fiscal year 2022.

Note 10. 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 as our corporate headquarters.

As of December 29, 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 December 29, 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 December 29, 2017 , we had outstanding purchase obligations with our suppliers or contract manufacturers of $20.4 million . In addition, we had contractual obligations of approximately  $0.7 million associated with software licenses as of December 29, 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 December 29, 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 December 29, 2017 , we had commercial commitments of $51.9 million outstanding that were not recorded in our unaudited condensed consolidated balance sheets. 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 products infringe the intellectual property rights of a third party. As of December 29, 2017 , we have not received any notices that any customer is subject to an infringement claim arising from the use of our products; we have not received any requests to defend any customers from infringement claims arising from the use of our 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 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 December 29, 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.

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.

Overview of Business; Operating Environment and Key Factors Impacting Fiscal 2018 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 herein, our fiscal year ending June 29, 2018 is referred to as "fiscal 2018 " or " 2018 " and our fiscal year ended June 30, 2017 is referred to as "fiscal 2017 " or " 2017 ".

We design, manufacture and sell a range of wireless networking products, solutions and services to mobile and fixed public network operators, federal, state and local government agencies, transportation, energy and utility companies, public safety agencies and broadcast network operations around the world. Our products utilize microwave and millimeter wave technologies to create point to point wireless links for short, medium and long distance interconnections. Our wireless systems deliver urban, suburban, regional and country-wide communication links as the primary alternative to fiber optic connections. In dense urban and suburban areas, short range wireless solutions are faster to deploy and lower cost per mile than new fiber deployments. In developing nations, fiber infrastructure is scarce and wireless systems are used for both long and short distance connections. Wireless systems are easier to implement than optical fiber in areas with rugged terrain, and are able to provide connections over bodies of water, such as between islands or between oil and gas production platforms. 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 and creates demand for our solutions, 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 may pursue our goals during the next twelve months through organic growth and through strategic alternatives. Some of these alternatives have included, and could continue to include, selective acquisitions of business segments or entire businesses, divestitures, the sale of assets or securities, a sale or merger of our company or a restructuring of our company. 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 continues to be adversely affected by constrained availability of U.S. dollars in countries with economies highly dependent on resource exports, particularly oil. This condition, along with decline in local purchasing power because of currency devaluations relative to the U.S. dollar, limits capital spending and slows payments from customers in those locations. 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 2017 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 six months ended December 29, 2017 and December 30, 2016 and the related changes were shown in the table below:

Our revenue in North America decreased $2.4 million , or 6.0% , during the second quarter of fiscal 2018 compared with the same period of fiscal 2017 . The volume of private network projects coming to completion decreased year-to-year but that was partially offset by a year-to-year increase in revenue with mobile operator customers in the sector. On a year-to-date basis, North America revenue increased slightly by $0.1 million , or 0.1% , compared with the same period in fiscal 2017 .

Our revenue in Africa and the Middle East decreased $4.1 million , or 24.4% , for the second quarter of fiscal 2018 compared with the same period of fiscal 2017 . The decrease in revenue was primarily due to lower sales volume to our large operator customers in Africa. On a year-to-date basis, Africa and the Middle East revenue decreased $5.0 million , or 16.0% , compared with the same period in fiscal 2017 . The year-to-date decrease in the region was also from lower sales to mobile operator customers in Africa.

Revenue in Europe and Russia increased $1.0 million , or 35.7% , for the second quarter of fiscal 2018 compared with the same quarter of fiscal 2017 . The increase was from sales to a new mobile operator customer in the region. On a year-to-date basis, revenue in Europe and Russia was up $0.9 million , or 12.9% , from the same period in fiscal 2017 . The increase was from sales to a new mobile operator customer in the region.

Revenue in Latin America and Asia Pacific decreased $1.4 million , or 14.2% , during the second quarter of fiscal 2018 compared with the same period in fiscal 2017 . 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 $4.9 million , or 23.8% , from the same period in fiscal 2017 mainly due to decreased sales to large mobile operator customers in Asia Pacific.

Our revenue from product sales decreased $8.2 million , or 17.9% , for the second quarter of fiscal 2018 compared with the same period in fiscal 2017 . Product volumes were $2.5 million lower in North America and $5.7 million lower in other regions. Our services revenue increased by $1.4 million , or 6.3% , during the second quarter of fiscal 2018 compared with the same period of fiscal 2017 , due to increased service activities in all regions except for Latin America.

Our revenue from product sales decreased by $7.9 million , or 9.8% , for the first six months of fiscal 2018 compared with the same period in fiscal 2017 . The decrease came primarily from weaker product sales in Africa, the Middle East, Latin America and Asia Pacific, offset in part by stronger sales in North America and Europe. Our services revenue decreased by $0.9 million , or 2.0% , during the first six months of fiscal 2018 compared with the same period of fiscal 2017 , due to reduced service activities in most regions, except for the Middle East Africa and Europe where we had a small increase in service sales.

Gross Margin

Gross margin for the three and six months ended December 29, 2017 increased by $0.8 million , or 3.7% , and $0.7 million , or 1.8% , respectively, compared with the three and six months ended December 30, 2016 . The margin increase resulted from improved product margins primarily in Africa and improved profitability of service projects in Africa, as well as an increase share of business in the North America market.

Gross margin as a percentage of revenue increased in the second quarter of fiscal 2018 compared with the same period in fiscal 2017 due to improved product and service margins, as well as an increase in the share of business in North America. Product margin as a percentage of product revenue increased from the prior year quarter primarily due to improvements of product margins in Africa facilitated by relative stability in exchange rates as well as the increased share of business in North America. Service margin as a percentage of service revenue increased due to continued efforts to improve execution of our field services projects, primarily in Africa.

On a year-to-date basis, gross margin as a percentage of revenue increased due to lower supply chain costs and higher margin on both product and service. Gross margin rates in our services businesses in most international sectors improved compared with the same period in fiscal 2017. Product margin as a percentage of product revenue increased in the first six months of fiscal 2018 over the same period in fiscal 2017 primarily due to reduced supply chain costs as well as the above-mentioned shift in the portion of our business coming from North America relative to international markets, and from improved product margins in Africa and Asia-Pacific.

Research and Development Expenses

Our research and development expenses increased $0.7 million , or 14.9% , in the second quarter of fiscal 2018 compared with the same period in fiscal 2017 . The increase was due to a $0.5 million increase in professional service expense and a $0.2 million increase in compensation and related employee expenses.

Our research and development expenses increased $0.5 million , or 5.6% , in the first six months of fiscal 2018 compared with the same period in fiscal 2017 . The increase was primarily due to a $0.5 million increase in compensation and related employee expenses and $0.2 million additional spending in professional service expense. The increase was offset by $0.1 million due to a higher economic incentive grant credit in the first six months of fiscal 2018.

Selling and Administrative Expenses

Our selling and administrative expenses increased $48.0 thousand , or 0.3% , in the second quarter of fiscal 2018 compared with the same periods in fiscal 2017 . The increase for the second quarter of fiscal 2018 compared with the same quarter in fiscal 2017 was primarily due to a $0.8 million bad debt recovery in the second quarter of fiscal 2017 that was not repeated in the current quarter and was offset by $0.2 million in savings in professional services expense and a $0.6 million savings in facilities costs due to our relocation to a new facility in fiscal 2017.

The decrease for the first six months of fiscal 2018 compared with the same period in fiscal 2017 was primarily due to a $1.0 million decrease in facility costs, a $0.4 million decrease in professional fees, a $0.3 million decrease in personnel costs and a $0.3 million decrease in depreciation expenses. The decrease was offset by a $0.7 million bad debt recovery in the first six months of fiscal 2017 that was not repeated in the first six months of fiscal 2018.
