Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
PRESENTATION OF FINANCIAL INFORMATION	'
	PRESENTATION OF FINANCIAL INFORMATION
	The unaudited condensed consolidated financial statements include the accounts of Microsemi Corporation and its subsidiaries. Intercompany transactions have been eliminated in consolidation.
	The condensed consolidated financial information furnished herein is unaudited, but in the opinion of our management, includes all adjustments (all of which are normal or recurring adjustments) necessary for a fair presentation of the results of operations for the periods indicated. The results of operations for the most recently reported quarter of the current fiscal year are not necessarily indicative of the results to be expected for the full year.
	The unaudited condensed consolidated financial statements have been prepared in accordance with the requirements of Form 10-Q and Article 10 of the Securities and Exchange Commission Regulation S-X, and therefore do not include all information and note disclosures necessary for a fair presentation of consolidated financial position, results of operations and cash flows in conformity with United States generally accepted accounting principles. The unaudited consolidated financial statements and notes thereto must be read in their entirety in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended September 29, 2013.
	The unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles, which require us to make estimates and assumptions that may materially affect the reported amounts of assets and liabilities at the date of the unaudited consolidated financial statements and revenues and expenses during the periods reported. Actual results could differ materially from those estimates. Information with respect to our critical accounting policies that we believe could have the most significant effect on our reported results and require subjective or complex judgments is contained in the notes to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended September 29, 2013. In referencing a year, we are referring to the fiscal year ended on the Sunday closest to September 30.
	Earnings Per Share
	Basic earnings per share have been computed based upon the weighted-average number of common shares outstanding during the respective periods. Diluted earnings per share have been computed, when the result is dilutive, using the treasury stock method for stock awards outstanding during the respective periods. Earnings per share were calculated as follows (amounts in thousands, except per share data):
		Quarter Ended
		December 29,		December 30,
		2013		2012
	Basic
	Net income	$	1,379	$	14,214
	Weighted-average common shares outstanding	92,102		88,535
	Basic earnings per share	$	0.01	$	0.16
	Diluted
	Net income	$	1,379	$	14,214
	Weighted-average common shares outstanding for basic	92,102		88,535
	Dilutive effect of stock awards	1,425		1,527
	Weighted-average common shares outstanding on a diluted basis	93,527		90,062
	Diluted earnings per share	$	0.01	$	0.16
	For the quarter ended December 29, 2013 and December 30, 2012, we excluded 2.7 million and 5.0 million, respectively, of stock awards in the computation of diluted earnings per share as these stock awards would have been anti-dilutive.
	Recently Issued Accounting Standards
	In December 2011, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2011-11, the objective of which is to provide additional disclosures on the effect or potential effect of rights of setoff associated with an entity's recognized assets and recognized liabilities within the scope of the update. The update primarily impacts financial instruments and derivatives subject to a master netting arrangement or similar agreement. ASU No. 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of this ASU did not impact our consolidated financial position, results of operations or cash flows.
	In February 2013, the FASB issued ASU No. 2013-04, the objective of which is to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. The guidance in the update requires that these arrangements be recorded as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. ASU 2013-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We are currently assessing the impact of this ASU on our consolidated financial position and results of operations.
	In July 2013, the FASB issued ASU No. 2013-11 which requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, with certain exceptions. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We are currently assessing the impact of this ASU but adoption will only have the potential of affecting the presentation of unrecognized tax benefits and will not impact our consolidated financial position, results of operations or cash flows.

ACQUISITION	'
	ACQUISITION
	On November 26, 2013, we, through a wholly owned subsidiary, acquired all the outstanding shares of Symmetricom, Inc. (“Symmetricom” or "Microsemi – FTD") for an estimated consideration of $312.7 million, of which $7.3 million was accrued at December 29, 2013. During the quarter ended December 29, 2013, we incurred $1.7 million in costs related to this acquisition that were recorded in selling, general and administrative expense. We acquired Symmetricom for its world-leading source of highly precise timekeeping technologies and solutions that enable next generation data, voice, mobile and video networks and services.
	We preliminarily allocated the total estimated consideration to Symmetricom's tangible and intangible assets and liabilities based on their estimated fair values as of the acquisition date and allocated the remaining amount to goodwill. The preliminary allocation is as follows (amounts in thousands):
	Cash and cash equivalents	$	26,337
	Accounts receivable	31,267
	Inventories	52,123
	Other current assets	66,617
	Property and equipment	19,366
	Other assets	26,927
	Identifiable intangible assets	110,800
	Goodwill	58,162
	Current liabilities	(36,524		)
	Deferred tax liabilities, net	(38,383		)
	Other non-current liabilities	(3,953		)
	Total estimated consideration	$	312,739
	As of the acquisition date, the gross contractual amount of acquired accounts receivable was $33.3 million and a preliminary estimate of contractual cash flows not expected to be collected was $2.1 million.
	The preliminary valuation of identifiable intangible assets and their estimated useful lives are as follows (amounts in thousands):
		Asset			Weighted
		Amount			Average
					Useful Life
					(Years)
	Completed technology	$	74,100		9
	Customer relationships	32,400			9
	Trade name	4,300			1
		$	110,800
	Valuation methodology
	The fair value of the identified intangible assets for the acquisition noted above was estimated by performing a discounted cash flow analysis using the “income” approach. This method includes a forecast of direct revenues and costs associated with the respective intangible assets and charges for economic returns on tangible and intangible assets utilized in cash flow generation. Net cash flows attributable to the identified intangible assets were discounted to their present value at a rate commensurate with the perceived risk. The projected cash flow assumptions considered contractual relationships, customer attrition, eventual development of new technologies and market competition.
	The valuation of completed technology and trade names for the acquisition noted above was based on the relief-from-royalty income approach, a variation of the income approach. The premise of the relief-from-royalty income approach is that if we had not been assigned the rights to the technology and trade names, we would have to pay royalties to continue to exploit the technology and trade names covered by their claims. To arrive at an estimate of royalty charges, the acquired entity's revenue and profit margins were analyzed to determine the ability to pay a royalty. In addition, the license databases were searched for actual royalty terms based on transactions involving technology and trade name licensing.
	The useful lives of completed technology rights are based on the number of years in which net cash flows have been projected. The useful lives of customer relationships are estimated based upon the length of the relationships currently in place, historical attrition patterns and natural growth and diversification of other potential customers. The useful life of a trade name was estimated based on the period in which a benefit could be ascribed to the identified trade names.
	Assumptions used in forecasting cash flows for each of the identified intangible assets included consideration of the following:
	•	Historical performance including sales and profitability.
	•	Business prospects and industry expectations.
	•	Estimated economic life of asset.
	•	Development of new technologies.
	•	Acquisition of new customers.
	•	Attrition of existing customers.
	•	Obsolescence of technology over time.
	Depending on the structure of a particular acquisition, goodwill and identifiable intangible assets may not be deductible for tax purposes. We determined that goodwill related to the Symmetricom acquisition is not deductible.
	The factors that contributed to a purchase price resulting in the recognition of goodwill include:
	•	The premium paid over market capitalization immediately prior to the merger announcement.
	•	Our belief that the merger will create a more diverse semiconductor company with expansive offerings which will enable us to expand our product offerings.
	•	Our belief that both companies are committed to improving cost structures and that our combined efforts after the merger should result in a realization of cost savings and an improvement of overall efficiencies.
	The purchase price allocation described above is preliminary. A final determination of fair values of assets acquired and liabilities assumed relating to the transaction could differ from the preliminary purchase price allocation and if material differences exist they could result in retrospective revision to the purchase price allocation. We utilized the straight line method of amortization for completed technology, customer relationships and trade name.
	Supplemental pro forma data
	The following supplemental pro forma data summarizes the results of operations for the quarters ended December 29, 2013 and December 30, 2012, as if we completed our acquisition of Microsemi – FTD as of the first day of 2013. The supplemental pro forma data reports actual operating results, adjusted to include the pro forma effect and timing of the impact in cost of goods sold from manufacturing profit in acquired inventory, acquisition-related expenses, restructuring and severance charges, amortization expense of identified intangible assets, incremental interest expense and the related tax effects of the acquisition. We recorded net sales of $21.2 million related to our acquisition of Microsemi – FTD. Earnings for this acquisition recorded on a standalone basis since the acquisition date are impracticable to determine, as on the acquisition date, we began to immediately integrate Microsemi – FTD into existing operations, engineering groups, sales distribution networks and management structure.
	The supplemental pro forma information presented is for illustrative purposes only and is not necessarily indicative of the financial position or results of operations that would have been realized if the transaction had been completed on the date indicated, does not reflect synergies that might have been achieved, nor is it indicative of future operating results or financial position. The pro forma adjustments are based upon currently available information and certain assumptions that we believe are reasonable under the circumstances.

	INCOME TAXES
	For the quarters ended December 29, 2013 and December 30, 2012, we recorded an income tax benefit of $2.1 million and a provision of $3.0 million, respectively. The difference in our effective tax rate from the U.S. statutory rate of 35 percent primarily reflects the ratio of domestic and international pre-tax income, valuation allowance and credits. Our tax benefit for the quarter ended December 29, 2013 was the combined calculated tax expenses/benefits for various jurisdictions, as well as a benefit for the release of valuation allowance of approximately $5.1 million, that resulted from the preliminary allocation of consideration from of our acquisition of Microsemi – FTD.
	We file U.S., state, and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2007 through 2013 tax years generally remain subject to examination by federal tax authorities, most state tax authorities and in significant foreign jurisdictions. Each quarter, we reassess our uncertain tax positions for additional unrecognized tax benefits, interest and penalties, and deletions due to statute expirations. Based on federal, state and foreign statute expirations in various jurisdictions, we anticipate a decrease in unrecognized tax benefits of $0.3 million within the next twelve months.
	We establish liabilities for possible assessments by tax authorities resulting from known tax exposures including, but not limited to, international tax issues and certain tax credits. The Internal Revenue Service (“IRS”) is currently examining our income tax returns for fiscal years 2007 through 2012. As of December 29, 2013, the IRS has raised questions primarily related to transfer pricing. Management believes that our position is appropriate and that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in our tax audits are resolved in a manner not consistent with management's expectations, we would be required to adjust our provision for income tax in the period such resolution occurs. While we believe our reported results are accurate, any significant adjustments could have a material adverse effect on our results of operations, cash flows and financial position if not resolved within expectations.

CREDIT AGREEMENT AND RELATED INSTRUMENTS	'
	CREDIT AGREEMENT AND RELATED INSTRUMENTS
	Credit Agreement
	We are a party to a senior secured credit facility with Morgan Stanley Senior Funding, Inc. ("MSSF") pursuant to a Credit Agreement, dated as of November 2, 2010, with MSSF and the lenders therein (as amended, the “Credit Agreement”), consisting of a term loan facility and a $50.0 million revolving credit facility. We can also request the establishment of one or more incremental loans with commitments in an aggregate amount not to exceed $50.0 million.
	During the quarter ended December 29, 2013, we entered into a commitment letter with MSSF pursuant to which MSSF committed to provide a $150.0 million incremental term loan under our term loan facility, which MSSF subsequently syndicated during the quarter. The incremental term loan was made available to (i) finance the acquisition of Symmetricom, (ii) repay any existing indebtedness of Symmetricom following the consummation of the merger, and (iii) pay fees and expenses related to the merger. The covenants under the incremental term loan are consistent with those in our existing Credit Agreement.
	Under our Credit Agreement, we may borrow under a "Base Rate" which approximates the prime rate or "Eurodollar Rate" which approximates LIBOR. The principal amount outstanding and interest rate per annum for each type of loan at December 29, 2013 are as follows (amounts in thousands):
		Principal Outstanding		Base Rate		Eurodollar Rate		Eurodollar Floor		Current Rate
	Revolving and swingline loans	$	—	3.5	%	4.5	%	—	%	—	%
	Term loan	$	676,000	1.75	%	2.75	%	1	%	3.75	%
	Incremental term loan	$	150,000	1.5	%	2.75	%	0.75	%	3.5	%
	Our term loan facility matures in February 2020 and principal amortizes at $7.3 million per year on our term loan and at $1.5 million per year on our incremental term loan. Due to prepayments of principal, there are currently no scheduled principal repayments until the maturity date though the Credit Agreement stipulates an annual payment of a percentage of Excess Cash Flow ("ECF"). The ECF percentage is between 0% and 50% depending on our consolidated leverage ratio as of the end of a fiscal year. The fair value of our term loans were $828.1 million at December 29, 2013 and $674.3 million at September 29, 2013, and we classify this valuation as a Level 2 fair value measurement.
	We currently pay an undrawn commitment fee of 0.375% on the unused portion of the revolving facility. If any letters of credit are issued, then we expect to pay a fronting fee equal to 0.25% per annum of the aggregate face amount of each letter of credit and a participation fee on all outstanding letters of credit at a per annum rate equal to the margin then in effect with respect to Eurodollar Rate-based loans on the face amount of such letter of credit.
	Our Credit Agreement includes financial covenants requiring a maximum leverage ratio and minimum fixed charge coverage ratio that are applicable only when revolving loans or swingline loans are outstanding at the end of a fiscal quarter and also contains other customary affirmative and negative covenants and events of default. We were in compliance with our covenants as of December 29, 2013.
	Interest Rate Swap Agreements
	In connection with our Credit Agreement, in 2011, we entered into interest rate swap agreements for the purpose of minimizing the variability of cash flows in the interest rate payments of our variable rate borrowings. The cash flows received under the interest rate swap agreements are expected to offset the change in cash flows associated with LIBOR rate borrowings between the effective and maturity dates of the swaps. Our two outstanding swap agreements have notional amounts, fixed rates and expiration dates are as follows: $121.0 million at 1.83% expiring January 2014 and $24.0 million at 2.21% expiring January 2015. We classify our interest rate swap balances as Level 2 fair value measurements. We determined the fair value of our interest rate swap agreements based on mid-market valuations reported to us by the counterparty to the swap agreements. Related to these interest rate swap agreements, we recorded a long-term liability of $0.3 million as of December 29, 2013. As of September 29, 2013, we had recorded a current liability of $0.3 million and a long-term liability of $0.4 million. We reflect the change in fair value of the swaps through other income (expense), net and recorded income of $0.3 million in both the first quarter of 2014 and 2013.

	FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES
	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Accounting Standards Codification ("ASC") 820 establishes a hierarchy for ranking the quality and reliability of the information used to determine fair values and includes the following classifications:
	Level 1: Quoted market prices in active markets for identical assets or liabilities.
	Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.
	Level 3: Unobservable inputs that are not corroborated by market data.

	We manage our business on the basis of one reportable segment, as a manufacturer of semiconductors in different geographic areas, including the United States, Europe and Asia. We derive revenue from sales of our high-performance analog/mixed-signal integrated circuits and power and high-reliability individual component semiconductors. These products include individual components as well as integrated circuit solutions that enhance customer designs by improving performance, reliability and battery optimization, reducing size or protecting circuits. The principal markets that we serve include Aerospace, Communications, Defense & Security, and Industrial. We evaluate sales by end-market based on our understanding of end market uses of our products.

	Stock Based Compensation
	In January 2012, our stockholders approved an amendment to the Microsemi Corporation 2008 Performance Incentive Plan (the “2008 Plan”). The amendment a) increased the share limit by an additional 14.5 million shares so that the amended aggregate share limit for the 2008 Plan is 28.5 million shares; b) extended the plan term to December 5, 2021; c) increased the number of shares counted against the share limit for every one share issued in connection with a full-value award to 2.41; d) terminated the evergreen provision in the original plan; and e) extended the Performance-Based Award feature through the first annual meeting of stockholders that occurs in calendar year 2017. Awards authorized by the 2008 Plan include options, stock appreciation rights, restricted stock, stock bonuses, stock units, performance share awards, and other cash- or share-based awards. The shares issued under the 2008 Plan may be newly issued or shares held by Microsemi as treasury stock. The maximum term of a stock option grant or a stock appreciation right granted under the 2008 Plan is 6 years. Stock-based compensation expense was $10.1 million for the quarter ended December 29, 2013 and $8.1 million for the quarter ended December 30, 2012.
	The quantity of restricted shares and performance stock units at target levels granted and their weighted-average fair value are as follows (quantities in thousands):
	Quarter Ended	Quantity	Weighted Average Fair Value per Award
	December 30, 2012
	Restricted shares	380	$	20
	Performance stock units	350	$	21.62

	Restricted shares	339	$	24.72
	Performance stock units	332	$	26.27
	Stock options assumed from acquisition	578	$	7.01
	Restricted Shares
	Compensation expense for restricted shares was calculated based on the closing price of our common stock on the date of grant and the restricted shares are subject to forfeiture if a participant does not meet length of service requirements. Restricted stock awards granted to employees typically vest over a three year period and awards granted to non-employee directors vest in accordance with our director compensation policy.
	Performance Stock Units
	Performance stock units granted in 2012 vested based on our growth in net sales and earnings per share (subject to certain adjustments) for 2012 and 2013 in comparison with the growth in net sales and adjusted earnings per share over the same period for a peer group selected by the Compensation Committee. For these performance stock units, 50% of each performance-based award opportunity were subject to the net sales metric for the performance period and 50% were subject to the earnings per share metric for the performance period. In November 2013, the Compensation Committee determined that 86% of the target number of units vested at the time of the committee's determination (which represents a vesting percentage of 116% based on the committee’s determination, minus the 30% of the target number of units that vested based on 2012 performance).
	Performance stock units granted in 2013 are eligible to vest based on our achievement of net sales and earnings per share (subject to certain adjustments) levels for 2013, 2014 and 2015. For these performance stock units, 25% of each performance-based award opportunity will be subject to the net sales metric for the performance period and 75% will be subject to the earnings per share metric for the performance period. In November 2013, the Compensation Committee determined that our performance did not exceed minimum thresholds. Accordingly, no performance units granted in 2013 vested.
	Performance units granted in 2014 are eligible to vest based on our rate of growth for net sales and earnings per share (subject to certain adjustments) over 2014, 2015 and 2016 relative to the growth rates for that metric over the relevant performance period for a peer group of companies. In addition, the vesting of the award will also be determined in part by our total shareholder return over the three-year period covered by the award relative to the peer group. A portion of the performance units may vest based on performance after each of the first two fiscal years of the performance period.
	Compensation expense is based upon either our estimate of performance relative to a peer group for the 2012 and 2014 grants and our expected performance over the performance period for the 2013 grant. For these performance stock units, 40% of each performance-based award opportunity will be subject to the net sales metric for the performance period and 60% will be subject to the earnings per share metric for the performance period. The maximum percentage for a particular metric is 200% of the “target” number of units subject to the award related to that metric. For performance stock units granted in 2013, the maximum percentage is further adjusted by our total shareholder return relative to a peer group selected by the Compensation Committee, up to a maximum of 125%.
	Stock Options
	We assumed unvested stock options related to our acquisition of Microsemi – FTD with a weighted average exercise price of $20.08 per stock option. We derived a weighted average fair value per stock option using the Black-Scholes option pricing model.

	In 2009, we approved consolidation plans that resulted in the closure of our manufacturing facility in Scottsdale, Arizona (“Scottsdale”), which ceased production during the quarter ended April 3, 2011. The Scottsdale facility occupied a 135,000 square foot leased facility. For Scottsdale, contract termination costs relate primarily to the remaining obligations under facility and equipment leases and are expected to be paid through 2016. The following table reflects the restructuring activities for the Scottsdale facility and the accrued liabilities in the consolidated balance sheets at the dates below (amounts in thousands):
		Facility Termination Costs
	Balance at September 29, 2013	$	4,507
	Cash expenditures	(436		)
	Balance at December 29, 2013	$	4,071
	At September 29, 2013, we had recorded severance and restructuring accruals of $2.2 million from reductions in force at our various facilities other than Scottsdale. We recorded additional provisions for severance and restructuring activities totaling $7.7 million for the quarter ended December 29, 2013, primarily related to activity following our acquisition of Microsemi – FTD. Provisions for severance in the quarter ended December 29, 2013 covered approximately 120 individuals in manufacturing, engineering and sales. Employee severance is expected to be paid within the next twelve months. Contract termination costs relate primarily to remaining obligations under facility leases and are expected to be paid through 2020. Other associated costs related primarily to relocation costs that we incurred for the consolidation of several facilities in Northern California. The following table reflects the related restructuring activities and the accrued liabilities in the consolidated balance sheets at the dates below (amounts in thousands):

	In Broomfield, Colorado, the owner of a property located adjacent to a manufacturing facility owned by one of our subsidiaries, Microsemi Corp. – Colorado, had notified the subsidiary and other parties of a claim that contaminants migrated to his property, thereby diminishing its value. In August 1995, the subsidiary, together with Coors Porcelain Company, FMC Corporation and Siemens Microelectronics, Inc. (former owners of the manufacturing facility), agreed to settle the claim and to indemnify the owner of the adjacent property for remediation costs. Although tricholorethylene and other contaminants previously used by former owners at the facility are present in soil and groundwater on the subsidiary’s property, we vigorously contest any assertion that the subsidiary caused the contamination. In November 1998, we signed an agreement with the three former owners of this facility whereby they have a) reimbursed us for $0.5 million of past costs, b) assumed responsibility for 90% of all future clean-up costs, and c) promised to indemnify and protect us against any and all third-party claims relating to the contamination of the facility. An Integrated Corrective Action Plan was submitted to the State of Colorado. Sampling and management plans were prepared for the Colorado Department of Public Health & Environment. State and local agencies in Colorado are reviewing current data and considering study and cleanup options. The most recent forecast estimated that the total project cost, up to the year 2020, would be approximately $5.3 million; accordingly, we recorded a one-time charge of $0.5 million for this project in 2003. There has not been any significant development since 2003.
	We are generally self-insured for losses and liabilities related to workers’ compensation and employer’s liability insurance. Accrued workers’ compensation liability was $1.5 million at December 29, 2013 and September 29, 2013. Our self-insurance accruals are based on estimates and, while we believe that the amounts accrued are adequate, the ultimate claims may be in excess of the amounts provided.
	We are involved in pending litigation, administrative and similar matters arising out of the normal conduct of our business, including litigation relating to acquisitions, employment matters, commercial transactions, contracts, environmental matters and matters related to compliance with governmental regulations. The ultimate aggregate amount of monetary liability or financial impact with respect to these matters is subject to many uncertainties and is therefore not predictable with assurance. In the opinion of management, the final outcome of these matters, if they are adverse, will not have a material adverse effect on our financial position, results of operations or cash flows. However, there can be no assurance with respect to such result, and monetary liability, financial impact or other sanctions imposed on us from these matters could differ materially from those projected.

	In December 2011, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2011-11, the objective of which is to provide additional disclosures on the effect or potential effect of rights of setoff associated with an entity's recognized assets and recognized liabilities within the scope of the update. The update primarily impacts financial instruments and derivatives subject to a master netting arrangement or similar agreement. ASU No. 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of this ASU did not impact our consolidated financial position, results of operations or cash flows.
	In February 2013, the FASB issued ASU No. 2013-04, the objective of which is to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. The guidance in the update requires that these arrangements be recorded as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. ASU 2013-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We are currently assessing the impact of this ASU on our consolidated financial position and results of operations.
	In July 2013, the FASB issued ASU No. 2013-11 which requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, with certain exceptions. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We are currently assessing the impact of this ASU but adoption will only have the potential of affecting the presentation of unrecognized tax benefits and will not impact our consolidated financial position, results of operations or cash flows.
