Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company and Basis of Presentation	The Company and Basis of Presentation
	The Company
	Aviat Networks, Inc. (the “Company,” “we,” “us,” and “our”) designs, manufactures and sells a range of wireless networking solutions and services to mobile and fixed telephone service providers, private network operators, government agencies, transportation and utility companies, public safety agencies and broadcast system operators across the globe. Our products include broadband wireless access base stations and customer premises equipment for fixed and mobile, point-to-point digital microwave radio systems for access, backhaul, trunking and license-exempt applications, supporting new network deployments, network expansion, and capacity upgrades.
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared by us in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, the statements do not include all information and footnotes required by U.S. GAAP for annual consolidated financial statements. In the opinion of our management, such interim financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of financial position, results of operations and cash flows for such periods. The results for the quarter and two quarters ended December 26, 2014 (the “second quarter and first two quarters of fiscal 2015”) 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 27, 2014.
	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned and majority owned subsidiaries. Significant intercompany transactions and accounts have been eliminated.
	We operate on a 52-week or 53-week year ending on the Friday nearest June 30. The first two quarters of fiscal 2015 and 2014 included 13 weeks in each quarter.
	Use of Estimates
	The preparation of consolidated financial statements in accordance with U.S. GAAP requires us to make estimates, assumptions and judgments affecting the amounts reported and related disclosures. Estimates are based upon historical factors, current circumstances and the experience and judgment of our management. We evaluate our estimates and assumptions on an ongoing basis and may employ outside experts to assist us in making these evaluations. Changes in such estimates, based on more accurate information, or different assumptions or conditions, may affect amounts reported in future periods. Such estimates affect significant items, including revenue recognition, provision for doubtful accounts, inventory valuation, valuation allowances for deferred tax assets, uncertainties in income taxes, restructuring obligations, product warranty obligations, share-based awards, contingencies and useful lives of property, plant and equipment.
	Summary of Significant Accounting Policies
	There have been no material changes in our significant accounting policies as of and for the first two quarters of fiscal 2015, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended June 27, 2014.
	Recently Adopted Accounting Standards
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued an amendment to the accounting guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or tax credit carryforward exists. This new guidance requires entities, if certain criteria are met, to present an unrecognized tax benefit, or portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward when such items exist in the same taxing jurisdiction. We adopted this new guidance in the first quarter of fiscal 2015 and the adoption of this standard did not have an effect on our consolidated financial position or results of operations.
	Recently Issued Accounting Standards
	On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for us beginning in our fiscal year 2018. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our consolidated financial position or results of operations.

Earnings Per Share [Abstract]
Net Loss Per Share of Common Stock	Net Loss Per Share of Common Stock
	We compute net income (loss) per share of common stock using the two-class method. Basic net income (loss) per share is computed using the weighted average number of common shares and participating securities outstanding. Our unvested restricted shares (including restricted stock awards and performance share awards) contain rights to receive non-forfeitable dividends and therefore are considered to be participating securities and would be included in the calculations of net income per basic and diluted common share. As we incurred net loss in all periods presented, all potential dilutive securities from stock options, restricted stocks and units and performance shares and units have been excluded from the diluted net loss per share calculations, as their effect would have been anti-dilutive. The following table summarizes the potential weighted average shares of common stock outstanding that have been excluded from the diluted net loss per share calculations:

Fair Value Disclosures [Abstract]
Fair Value Measurements Of Assets And Liabilities	Fair Value Measurements of Assets and Liabilities
	We determine fair value as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants as of the measurement date. We maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value and establish a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows:
	•	Level 1 — Observable inputs such as quoted prices in active markets for identical assets or liabilities;
	•	Level 2 — Observable market-based inputs or observable inputs that are corroborated by market data; and
	•	Level 3 — Unobservable inputs reflecting our own assumptions.
	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 26, 2014 and June 27, 2014 were as follows:
		December 26, 2014				June 27, 2014				Valuation Inputs
		Cost		Fair Value		Cost		Fair Value
		(In millions)
	Assets:
	Cash equivalents:
	Money market funds	$	5.5	$	5.5	$	10.2	$	10.2	Level 1
	Bank certificates of deposit	$	0.2	$	0.2	$	3.5	$	3.5	Level 2
	We classify items within Level 1 if quoted prices are available in active markets. Our Level 1 items include shares in money market funds purchased from two major financial institutions. As of December 26, 2014 and June 27, 2014, these money market shares were valued at $1.00 net asset value per share by these financial institutions.
	We classify items in Level 2 if the observable inputs to quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources are available with reasonable levels of price transparency. Our bank certificates of deposit and foreign exchange forward contracts are classified within Level 2. Foreign currency forward contracts are measured at fair value using observable foreign currency exchange rates. The assets and liabilities related to our foreign currency forward contracts were not material as of December 26, 2014 and June 27, 2014.
	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 two quarters of fiscal 2015 and 2014, we had no transfers between levels of the fair value hierarchy of our assets or liabilities measured at fair value.

Debt Disclosure [Abstract]
Credit Facility And Debt	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”), which was amended on September 25, 2014, October 30, 2014 and December 2, 2014 providing for the extensions of deadline for preparing and filing our fiscal 2014 financial statements with the Securities and Exchange Commission (the “SEC”). This agreement amends and restates our existing First Amended and Restated Loan and Security Agreement, which was entered into on September 27, 2013 and amended providing for certain amendments to the maximum borrowing limit and financial covenants. Our outstanding debt balance under the SVB Credit Facility was $9.0 million and $6.0 million as of December 26, 2014 and June 27, 2014.
	The SVB Credit Facility provides for a committed amount of up to $40.0 million, with a $30.0 million sublimit that can be borrowed by our Singapore subsidiary. Borrowings that may be advanced under the SVB Credit Facility at the lesser of $40.0 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. Principal, together with all accrued and unpaid interest, is due and payable on September 26, 2016. We may prepay loans under the SVB Credit Facility in whole or in part at any time without premium or penalty. As of December 26, 2014, available credit under the SVB Credit Facility was $13.2 million reflecting the calculated borrowing base of $28.1 million less existing borrowings of $9.0 million and outstanding letters of credit of $5.9 million.
	Borrowings under the SVB Credit Facility carry 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. If a minimum adjusted quick ratio requirement is satisfied, LIBOR advances are offered at LIBOR plus a spread of 2.75%. Interest is due and payable in arrears monthly for prime rate loans and, for LIBOR rate loans, at the end of an interest period or at each three-month interval if the interest period is greater than three months. During the first two quarters of fiscal year 2015, the weighted average interest rate on our outstanding loan was 3.8%.
	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 2.00% above the applicable interest rate.
	As of December 26, 2014, we were in compliance with the quarterly financial covenants contained in the SVB Credit Facility. However, as a result of uncertainty on our ability to meet the financial covenants and the fact that the SVB Credit Facility contains subjective acceleration clauses that could be triggered by the lender, the $9.0 million borrowing was classified as a current liability as of December 26, 2014.

	Fiscal 2014-2015 Plan
	During the third quarter of fiscal 2014, in line with the decrease in revenue that we experienced and our reduced forecast for the immediate future, we initiated a restructuring plan (the “Fiscal 2014-2015 Plan”) to reduce our operating costs, primarily in North America, Europe and Asia. Activities under the Fiscal 2014-2015 Plan primarily include reductions in force and additional facility downsizing of our Santa Clara, California headquarters.
	The following table summarizes our costs incurred during the second quarter and first two quarters of fiscal 2015, estimated additional costs to be incurred and estimated total costs expected to be incurred as of December 26, 2014 under the Fiscal 2014-2015 Plan:

	During the second quarter of fiscal 2015, we decided to keep several U.S. employees who were previously included in the reduction of workforce and, therefore, accrued severance and benefits charges related to these employees were reversed during the quarter. We intend to substantially complete the remaining restructuring activities under the Fiscal 2014-2015 Plan in fiscal 2015.
	Fiscal 2013-2014 Plan
	During the fourth quarter of fiscal 2013, we initiated a restructuring plan (the “Fiscal 2013-2014 Plan”) to bring our cost structure in line with the changing business environment of the worldwide microwave radio and telecommunication markets, primarily in North America, Europe and Asia. Activities under the Fiscal 2013-2014 Plan include reductions in force and the downsizing of our Santa Clara, California headquarters and certain U.S. and international field offices to reduce our operating expenses.
	The following table summarizes our costs incurred during the second quarter and first two quarters of fiscal 2015 and 2014, estimated additional costs to be incurred and estimated total costs expected to be incurred as of December 26, 2014 under the Fiscal 2013-2014 Plan:

We substantially completed the restructuring activities under the Fiscal 2013-2014 Plan in fiscal 2014. As of December 26, 2014, the remaining additional costs to be incurred under the Fiscal 2013-2014 Plan primarily related to our facility charges through the applicable remaining lease term.

	In March 2011, our board of directors approved a plan for the sale of our WiMAX business. On September 2, 2011, we sold to EION Networks, Inc. (“EION”) our WiMAX business and related assets consisting of certain technology, inventory and equipment. As consideration for the sale of assets, EION agreed to pay us $0.4 million in cash and up to $2.8 million in additional cash payments contingent upon specific factors related to future WiMAX business performance. As of December 26, 2014, we received $0.1 million of such contingent payments and do not expect any further payments from EION. In addition, EION is entitled to receive cash payments up to $2.0 million upon collection of certain WiMAX accounts receivable. As of September 26, 2014, we have paid $1.6 million to EION and reduced $0.4 million of our liability to EION primarily resulting from the write-down of the corresponding WiMAX accounts receivable. Therefore, the accrued liabilities due to EION related to the disposition of the WiMAX business have been zero since September 26, 2014.
	In the third quarter of fiscal 2011, we began accounting for the WiMAX business as a discontinued operation and, therefore, the operating results of our WiMAX business were included in discontinued operations in our condensed consolidated financial statements for all periods presented. The income recognized in the first two quarters of fiscal 2015 was primarily due to a gain on disposition of WiMAX resulting from a write-off of accrued liabilities due to EION.
	Summary results of operations for the WiMAX business were as follows:

	2007 Stock Equity Plan and Activities
	As of December 26, 2014, we had one stock incentive plan for our employees and nonemployee directors, the 2007 Stock Equity Plan, as amended and restated effective November 17, 2011 (the “2007 Stock Plan”). The 2007 Stock Plan provides for accelerated vesting of certain share-based awards if there is a change in control of the Company. The 2007 Stock Plan also provides for the issuance of share-based awards in the form of stock options, stock appreciation rights, restricted stock awards and units, and performance share awards and units. We have various incentive programs under the 2007 Stock Plan, including annual and long-term incentive programs (“AIP” or “LTIP”), a global equity program (“GEP”) and product development incentive programs (“PDIP”).
	Under the 2007 Stock Plan, option exercise prices are equal to the fair market value on the date the options are granted using our closing stock price. Options may be exercised for a period set at the time of grant, which is generally seven years after the date of grant. Options generally vest in installments on one of three vesting schedules: (1) 50% one year from the grant date and 25% each year thereafter over a three-year period from the date of grant; (2) one-third annually over a three-year period from the date of grant; or (3) one-fourth annually over a four-year period from date of grant. Stock options are issued to directors annually and generally vest on the day before the annual stockholders’ meeting.
	Restricted stock is not transferable until vested and the restrictions lapse upon the achievement of continued employment or service over a specified time period. Restricted stock issued to employees generally vests either one-third annually over a three-year period from the date of grant or in full three years after the grant date. Restricted stock is issued to directors annually and generally vests on the day before the annual stockholders’ meeting.
	Vesting of performance shares under our AIP, LTIP or GEP is subject to financial performance criteria including revenue, operating income, or cash flow targets for the periods as defined in the programs and continued employment through the end of the applicable period. Performance shares under our PDIPs are issued to employees related to certain new product development projects and vest upon achievement of the product development milestones as defined in the programs.
	During the first two quarters of fiscal 2015, we granted options to purchase 216,787 shares of our common stock to employees under our 2007 Stock Plan.
	Upon the exercise of stock options, vesting of restricted stock awards and units, or vesting of performance share awards and units, we issue new shares of our common stock to our employees. All awards that are canceled 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 4,152,316 as of December 26, 2014.
	Share-Based Compensation
	Total compensation expense for share-based awards included in our condensed consolidated statements of operations for the second quarter of fiscal 2015 and 2014 was as follows:

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

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes
	Our effective tax rate varies from the U.S. federal statutory rate of 35% due to results of foreign operations that are subject to income taxes at different statutory rates and certain jurisdictions where we cannot recognize tax benefits on current losses. During interim periods, we accrue tax expenses for foreign jurisdictions that are anticipated to be profitable for fiscal 2015.
	The determination of our provision for the first two quarters of fiscal 2015 and 2014 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 two quarters of fiscal 2015 was primarily attributable to tax expense related to profitable foreign subsidiaries.
	We have a number of years with open tax audits which vary from jurisdiction to jurisdiction. Our major tax jurisdictions include the U.S., Singapore and Nigeria. The earliest years that are open and subject to potential audits for these jurisdictions are as follows: U.S. — 2003; Singapore — 2006; and Nigeria — 2011.
	We account for interest and penalties related to unrecognized tax benefits as part of our provision for federal, foreign, and state income taxes. Such interest expense we accrued for was not material for the second quarter and first two quarters of fiscal 2015 and fiscal 2014.

Commitments and Contingencies	Commitments and Contingencies
	Operating Lease Commitments
	We lease office and manufacturing facilities under non-cancelable operating leases expiring at various dates through April 2020. We lease approximately 129,000 square feet of office space in Santa Clara, California as our corporate headquarters. Beginning in the first quarter of fiscal 2015, approximately three-fourths of our Santa Clara headquarters building was vacated and made available for sublease. As of December 26, 2014, future minimum lease payments for our headquarters totaled $13.9 million.
	As of December 26, 2014, our future minimum lease payments under all non-cancelable operating leases with an initial lease term in excess of one year were as follows:

	Thereafter (through April 2020)	2.3
	Total	$	17
	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 total minimum rentals to be received in the future under our non-cancelable subleases was $0.1 million as of December 26, 2014.
	Rental expense for operating leases, including rentals on a month-to-month basis, was as follows:
		Quarter Ended				Two Quarters Ended

	Rent expense	$	1.6	$	1.6	$	3.4	$	3.8
	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 26, 2014, we had outstanding purchase obligations with our suppliers or contract manufacturers of $31.6 million.
	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 26, 2014, 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 26, 2014, we had commercial commitments of $49.3 million outstanding that were not recorded in our condensed consolidated balance sheets. We do not believe, based on historical experience and information currently available, that it is probable that any amounts will be required to be paid on the performance guarantees.
	Indemnifications
	Under the terms of substantially all of our license agreements, we have agreed to defend and pay any final judgment against our customers arising from claims against such customers that our software products infringe the intellectual property rights of a third party. As of December 26, 2014, 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 December 26, 2014, we had not recorded any liabilities related to these indemnifications.
	Legal Proceedings
	From time to time, we may be involved in various legal claims and litigation that arise in the normal course of our operations. We 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.
	While the results of such claims and litigation cannot be predicted with certainty, we currently believe that we are not a party to any litigation the final outcome of which is likely to have a material adverse effect on our financial position, results of operations or cash flows. However, should we not prevail in any such litigation; it could have a material adverse impact on our operating results, cash flows or financial position.
	Contingent Liabilities
	We record a loss contingency as a charge to operations when (i) it is probable that an asset has been impaired or a liability has been incurred at the date of the financial statements; and (ii) the amount of the loss can be reasonably estimated. Disclosure in the notes to the financial statements is required for loss contingencies that do not meet both those conditions if there is a reasonable possibility that a loss may have been incurred. Gain contingencies are not recorded until realized. We expense all legal costs incurred to resolve regulatory, legal and tax matters as incurred.
	Our Singapore subsidiary is in the process of evaluating its historical compliance with certain export regulations in Singapore. Depending on the results of this evaluation, we may take additional actions to ensure our compliance with these regulations in the future. As part of these additional actions, we could elect to make certain voluntary disclosures, which may, in certain circumstances, result in the imposition of various fines and penalties. Any fines and penalties will be based on the specific facts and findings of our evaluation, as well as negotiation with Singapore authorities. At this time, we cannot estimate the amount or range of any fines and penalties, if any should be imposed.
	Periodically, we review the status of each significant matter to assess the potential financial exposure. If a potential loss is considered probable and the amount can be reasonably estimated, we reflect the estimated loss in our results of operations. Significant judgment is required to determine the probability that a liability has been incurred or an asset impaired and whether such loss is reasonably estimable. Further, estimates of this nature are highly subjective, and the final outcome of these matters could vary significantly from the amounts that have been included in our consolidated financial statements. As additional information becomes available, we reassess the potential liability related to our pending claims and litigation and may revise estimates accordingly. Such revisions in the estimates of the potential liabilities could have a material impact on our results of operations and financial position.

Basis of Presentation	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared by us in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, the statements do not include all information and footnotes required by U.S. GAAP for annual consolidated financial statements. In the opinion of our management, such interim financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of financial position, results of operations and cash flows for such periods. The results for the quarter and two quarters ended December 26, 2014 (the “second quarter and first two quarters of fiscal 2015”) 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 27, 2014.
	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned and majority owned subsidiaries. Significant intercompany transactions and accounts have been eliminated.
	We operate on a 52-week or 53-week year ending on the Friday nearest June 30. The first two quarters of fiscal 2015 and 2014 included 13 weeks in each quarter.
Use of estimates	Use of Estimates
	The preparation of consolidated financial statements in accordance with U.S. GAAP requires us to make estimates, assumptions and judgments affecting the amounts reported and related disclosures. Estimates are based upon historical factors, current circumstances and the experience and judgment of our management. We evaluate our estimates and assumptions on an ongoing basis and may employ outside experts to assist us in making these evaluations. Changes in such estimates, based on more accurate information, or different assumptions or conditions, may affect amounts reported in future periods. Such estimates affect significant items, including revenue recognition, provision for doubtful accounts, inventory valuation, valuation allowances for deferred tax assets, uncertainties in income taxes, restructuring obligations, product warranty obligations, share-based awards, contingencies and useful lives of property, plant and equipment.
Recently Issued and Adopted Accounting Standards	Recently Adopted Accounting Standards
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued an amendment to the accounting guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or tax credit carryforward exists. This new guidance requires entities, if certain criteria are met, to present an unrecognized tax benefit, or portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward when such items exist in the same taxing jurisdiction. We adopted this new guidance in the first quarter of fiscal 2015 and the adoption of this standard did not have an effect on our consolidated financial position or results of operations.
	Recently Issued Accounting Standards
	On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for us beginning in our fiscal year 2018. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our consolidated financial position or results of operations.
