Accounting Policies [Abstract]

Basis of Presentation and Significant Accounting Policies

Basis of Presentation and Significant Accounting Policies:

The accompanying Condensed Consolidated Financial Statements are unaudited and have been prepared by Lattice Semiconductor Corporation (“Lattice,” the “Company,” “we,” “us” or “our”) pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and in our opinion include all adjustments, consisting of normal recurring adjustments, necessary for the fair statement of results for the interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. These Condensed Consolidated Financial Statements should be read in conjunction with our audited financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 29, 2012.

We report based on a 52 or 53-week fiscal year ending on the Saturday closest to December 31. Our second quarter of fiscal 2013 and second quarter of fiscal 2012 ended on June 29, 2013 and June 30, 2012, respectively. All references to quarterly, three or six months ended financial results are references to the results for the relevant fiscal period.

Principles of Consolidation

The accompanying Condensed Consolidated Financial Statements include the accounts of Lattice and its subsidiaries, all of which are wholly-owned, after the elimination of all intercompany balances and transactions. Certain balances in prior fiscal years have been reclassified to conform to the presentation adopted in the current year.

Cash Equivalents and Marketable Securities

We consider all investments that are readily convertible into cash and have original maturities of three months or less, to be cash equivalents. Cash equivalents consist primarily of highly liquid investments in time deposits or money market accounts and are carried at cost. We account for marketable securities as available for sale with unrealized gains or losses recorded to Accumulated other comprehensive income (loss), unless losses are considered other-than-temporary, in which case, losses are charged to the Consolidated Statements of Operations and Comprehensive Income (Loss).

Fair Value of Financial Instruments

We invest in various financial instruments including corporate and government bonds, notes, commercial paper and auction rate securities. The Company values these instruments at their fair value and monitors their portfolio for impairment on a periodic basis. In the event that the carrying value of an investment exceeds its fair value and the decline in value is determined to be other than temporary, the Company records an impairment charge and establishes a new carrying value. We assess other-than-temporary impairment of marketable securities in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures.” The framework under the provisions of ASC 820 establishes three levels of inputs that may be used to measure fair value. Each level of input has different levels of subjectivity and difficulty involved in determining fair value.

Level 1 instruments are characterized generally by quoted prices for identical assets or liabilities in active markets. Therefore, determining fair value for Level 1 instruments generally does not require significant management judgment, and the estimation is not difficult.

Level 2 instruments include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices for identical instruments in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 instruments include unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Our auction rate securities are classified as Level 3 instruments. Management uses a combination of the market and income approach to derive the fair value of auction rate securities, which includes third party valuation results, investment broker provided market information and available information on the credit quality of the underlying collateral. As a result, the determination of fair value for Level 3 instruments requires significant management judgment and subjectivity. Our Level 3 instruments are classified as Long-term marketable securities on our Condensed Consolidated Balance Sheet and are entirely made up of auction rate securities that consist of student loan asset-backed notes. Such loans are insured by the federal government or guaranteed by the Federal Family Educational Loan Program ("FFELP"). Fair value measurement may be sensitive to various unobservable inputs such as the ability of students to repay their loans, or change in the provision of government guarantees policy toward guaranteeing loan repayment. If students are unable to pay back their loans or the government changes its policy, our investments may be further impaired.

Foreign Exchange and Translation of Foreign Currencies

We have international subsidiary and branch operations. In addition, a portion of our silicon wafer and other purchases are denominated in Japanese yen and we bill certain Japanese customers in yen. Gains or losses from foreign exchange rate fluctuations on balances denominated in foreign currencies are reflected in Other (expense) income, net. Realized and unrealized gains or losses on foreign currency transactions were not significant for the periods presented. We translate accounts denominated in foreign currencies in accordance with ASC 830, “Foreign Currency Matters,” using the current rate method under which asset and liability accounts are translated at the current rate, while stockholders' equity accounts are translated at the appropriate historical rates, and revenue and expense accounts are translated at average monthly exchange rates. Translation adjustments related to the consolidation of foreign subsidiary financial statements are reflected in Accumulated other comprehensive loss in Stockholders' equity.

Derivative Financial Instruments

At June 29, 2013 and December 29, 2012, we had open foreign exchange contracts of 100,000,000 JPY and 150,000,000 JPY, respectively. The contracts outstanding at June 29, 2013 and December 29, 2012 were settled in July 2013 and January 2013, respectively. Although such hedges mitigate our foreign currency exchange rate exposure from an economic perspective, they were not designated as "effective" hedges for accounting purposes and are adjusted to fair value through earnings, with an impact of less than $0.1 million for the periods reported. We do not hold or issue derivative financial instruments for trading or speculative purposes.

Concentration Risk

Potential exposure to concentration risk consists primarily of cash and cash equivalents, marketable securities, trade receivables and supply of wafers for our new products. We place our investments primarily through three financial institutions and mitigate the concentration of credit risk by limiting the maximum portion of the investment portfolio which may be invested in any one instrument. The Company's investment policy defines approved credit ratings for investment securities. Investments on-hand consisted primarily of money market instruments, “AA” or better corporate notes and bonds, and U.S. government agency obligations. See Note 4 for a discussion of the liquidity attributes of our marketable securities.

Concentration of credit risk with respect to trade receivables is mitigated by a geographically diverse customer base and our credit and collection process. Accounts receivable do not bear interest, and are shown net of allowances for doubtful accounts of $1.2 million and $1.1 million at June 29, 2013 and December 29, 2012, respectively. We perform credit evaluations for essentially all customers and secure transactions with letters of credit or advance payments where appropriate. We regularly review our allowance for doubtful accounts and the aging of our accounts receivable. Write-offs for uncollected trade receivables have not been significant to date.

We rely on a limited number of foundries for our wafer purchases including: Fujitsu Limited, Seiko Epson Corporation Taiwan Semiconductor Manufacturing Company, Ltd, United Microelectronics Corporation, and GLOBALFOUNDRIES.

Revenue Recognition and Deferred Income

We sell our products directly to end customers or through a network of independent manufacturers' representatives and indirectly through a network of independent sell-in and sell-through distributors. Distributors provide periodic data regarding the product, price, quantity, and end customer when products are resold, as well as the quantities of our products they still have in stock.

Revenue from sales to original equipment manufacturers ("OEMs") or sell-in distributors is recognized upon shipment. Revenue from sales by our sell-through distributors is recognized at the time of reported resale. Under both types of revenue recognition, persuasive evidence of an arrangement exists, the price is fixed or determinable, title has transferred, collection of resulting receivables is reasonably assured, there are no remaining customer acceptance requirements and no remaining significant performance obligations.

Orders from our sell-through distributors are initially recorded at published list prices; however, for a majority of our sales, the final selling price is determined at the time of resale and in accordance with a distributor price agreement. In certain circumstances, we allow sell-through distributors to return unsold products. At times, we protect our sell-through distributors against reductions in published list prices. For these reasons, we do not recognize revenue until products are resold by sell-through distributors to an end customer.

For sell-through distributors, at the time of shipment to distributors, we (a) record Accounts receivable, net at published list price since there is a legally enforceable obligation from the distributor to pay us currently for product delivered, (b) relieve inventory for the carrying value of goods shipped since legal title has passed to the distributor, and (c) record deferred revenue and deferred cost of sales in Deferred income and allowances on sales to sell-through distributors in the liability section of our Consolidated Balance Sheets. The final price is set at the time of resale and is determined in accordance with a distributor price agreement. Revenue and cost of products sold to sell-through distributors are deferred until either the product is resold by the distributor or, in certain cases, return privileges terminate, at which time Revenue and Cost of products sold are reflected in Net Income (loss), and Accounts receivable, net are adjusted to reflect the final selling price.

The components of Deferred income and allowances on sales to sell-through distributors are presented in the following table (in thousands):



	June 29, 2013			December 29, 2012
Inventory valued at published list price and held by sell-through distributors with right of return	$	43,571		$	38,623
Allowance for distributor advances	(23,890		)	(22,450		)
Deferred cost of sales related to inventory held by sell-through distributors	(5,791		)	(5,620		)
Total Deferred income and allowances on sales to sell-through distributors	$	13,890		$	10,553

We expect a significant portion of our revenue in fiscal 2013 will be from sell-through distributors. Resale of products by sell-through distributors as a percentage of total revenue was 44% and 46% for the three and six months ended June 29, 2013, respectively, and 56% and 55% for the three and six months ended June 30, 2012, respectively.

We must use estimates and apply judgment to reconcile sell-through distributors' reported inventories to their activities. Errors in our estimates or judgments could result in inaccurate reporting of our Revenue, Cost of products sold, Deferred income and allowances on sales to sell-through distributors, and Net Income (loss).

Revenue from software licensing was not material for the periods presented.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and classification of assets, such as marketable securities, accounts receivable, net, inventory, auction rate securities, goodwill - including the assessment of reporting unit, intangible assets, current and deferred income taxes, accrued liabilities - including restructuring charges and bonus arrangements, deferred income and allowances on sales to sell-through distributors, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the fiscal periods presented. Actual results could differ from those estimates.

New Accounting Pronouncements	6 Months Ended
New Accounting Pronouncements	Jun. 29, 2013
Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements: In February 2013, the FASB issued amendments to the FASB Accounting Standards Codification relating to the reporting of reclassifications out of accumulated other comprehensive income. The amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. We were required to adopt these amendments in the first quarter of fiscal 2013. In June 2013, the Emerging Issues Task Force ("EITF") reached consensus on ASU 2013-11 Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The consensus requires companies to present the unrecognized tax benefit as a reduction of the Deferred tax asset for a Net Operating Loss ("NOL") or similar tax loss, or tax credit carryforward rather than as a liability when the uncertain tax position would reduce the NOL or other carryforward under the tax law. We early adopted this requirement in June of 2013 with retrospective application as permitted by the standard. Amounts presented in prior periods have been reclassified to conform. This resulted in both long-term taxes payable and deferred tax assets declining by approximately $14 million for all periods presented.

Net Income (Loss) Per Share

Earnings Per Share [Abstract]

Net Income (Loss) Per Share

Net income (loss) Per Share:

We compute basic net income (loss) per share by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. To determine diluted share count, we apply the treasury stock method to determine the dilutive effect of outstanding stock option shares, restricted stock units ("RSUs"), and Employee Stock Purchase Plan ("ESPP") shares. Our application of the treasury stock method includes as assumed proceeds, the average unamortized stock-based compensation expense for the period and the impact of the pro forma deferred tax benefit or cost associated with stock-based compensation expense.

A reconciliation of basic and diluted Net income (loss) per share is presented below (in thousands, except per share data):



	Three Months Ended					Six Months Ended
	June 29, 2013		June 30, 2012			June 29, 2013		June 30, 2012
Basic and diluted Net Income (loss)	$	5,040	$	(12,542	)	$	6,930	$	(20,256	)
Shares used in basic Net Income (loss) per share	115,733		117,874			115,562		118,024
Dilutive effect of stock options, RSUs and ESPP shares	1,376		—			1,373		—
Shares used in diluted Net Income (loss) per share	117,109		117,874			116,935		118,024
Basic Net Income (loss) per share	$	0.04	$	(0.11	)	$	0.06	$	(0.17	)
Diluted Net Income (loss) per share	$	0.04	$	(0.11	)	$	0.06	$	(0.17	)

The computation of diluted Net income per share for the three and six months ended June 29, 2013, includes the effects of stock options, RSUs and ESPP shares aggregating approximately 1.4 million shares and 1.4 million shares, respectively, as they are dilutive, and excludes the effects of stock options, RSUs and ESPP shares aggregating approximately 9.6 million shares and 8.2 million shares, respectively, as they are antidilutive. The computation of diluted Net loss per share for both the three and six months ended June 30, 2012 excludes the effects of stock options, RSUs and ESPP shares aggregating approximately 12.2 million shares, as they are antidilutive. Stock options, RSUs and ESPP shares are considered antidilutive when the aggregate of exercise price, unrecognized stock-based compensation expense and excess tax benefit are greater than the average market price for our common stock during the period or when the Company is in a net loss position. Stock options and RSUs that are dilutive in the second quarter and first six months of fiscal 2013 could become antidilutive in the future.

	Par Value		Fair Value		S&P Credit rating	Par Value		Fair Value		S&P Credit rating
Long-term marketable securities:
Federally-insured or FFELP guaranteed student loans	$	5,700	$	4,717	AA+	$	5,700	$	4,717	AA+
Total auction rate securities	$	5,700	$	4,717		$	5,700	$	4,717

At June 29, 2013, due to continued multiple failed auctions and a determination of illiquidity, the auction rate securities held by us are classified as Long-term marketable securities. These auction rate securities are exposed to risks associated with student loan asset-backed notes. Such loans are insured by the federal government or guaranteed by the FFELP. We intend to sell our auction rate securities as markets for these securities resume or reasonable offers become available.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments (in thousands):



	Fair value measurements as of June 29, 2013										Fair value measurements as of December 29, 2012
	Total			Level 1		Level 2			Level 3		Total			Level 1		Level 2			Level 3
Short-term marketable securities	$	74,948		$	74,948	$	—		$	—	$	64,865		$	64,865	$	—		$	—
Long-term marketable securities	4,717			—		—			4,717		4,717			—		—			4,717

We invest in various financial instruments including corporate and government bonds and notes, commercial paper and auction rate securities. In addition, we enter into foreign currency forward exchange contracts to mitigate our foreign currency exchange rate exposure. We carry these instruments at their fair value in accordance with ASC 820. The framework under the provisions of ASC 820 establishes three levels of inputs that may be used to measure fair value. Each level of input has different levels of subjectivity and difficulty involved in determining fair value.

Level 1 instruments generally represent quoted prices for identical assets or liabilities in active markets. Therefore, determining fair value for Level 1 instruments generally does not require significant management judgment, and the estimation is not difficult. Our Level 1 instruments consist of federal agency, corporate notes and bonds, and commercial paper that are traded in active markets and are classified as Short-term marketable securities on our Condensed Consolidated Balance Sheet.

Level 3 instruments include unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Our auction rate securities are classified as Level 3 instruments. Management uses a combination of the market and income approach to derive the fair value of auction rate securities, which include third party valuation results, investment broker provided market information and available information on the credit quality of the underlying collateral. As a result, the determination of fair value for Level 3 instruments requires significant management judgment and subjectivity. Our Level 3 instruments are classified as Long-term marketable securities on our Condensed Consolidated Balance Sheet and are entirely made up of auction rate securities that consist of student loan asset-backed notes. Such loans are insured by the federal government or guaranteed by the FFELP. Fair value measurement may be sensitive to various unobservable inputs such as the ability of students to repay their loans, or change in the provision of government guarantees policy toward guaranteeing loan repayment. If students are unable to pay back their loans or the government changes its policy, our investments may be further impaired.

There were no transfers between Levels 1 and 2 during the first six months ended fiscal 2013 or 2012. There were no transfers into or out of Level 3 during the first six months ended fiscal 2013 or 2012.

During the six months ended June 29, 2013 and June 30, 2012, the following changes occurred in our Level 3 instruments (in thousands):



	Six Months Ended
	June 29, 2013		June 30, 2012
Beginning fair value of Long-term marketable securities	$	4,717	$	6,946
Fair value of securities sold or redeemed	—		(2,285		)
Ending fair value of Long-term marketable securities	$	4,717	$	4,661

In accordance with ASC 320, “Investments-Debt and Equity Securities,” we recorded an unrealized gain of less than $0.1 million during the six months ended June 29, 2013 and an unrealized gain of less than $0.1 million during the six months ended June 30, 2012, on certain Short-term marketable securities (Level 1 instruments), which has been recorded in Accumulated other comprehensive loss. Future fluctuations in fair value related to these instruments that the Company deems to be temporary, including any recoveries of previous write-downs, would be recorded to Accumulated other comprehensive loss. If we were to determine in the future that any further decline in fair value is other-than-temporary, we would record an impairment charge, which could have a materially detrimental impact on our operating results. If we were to liquidate our position in these securities, it is likely that the amount of any future realized gain or loss would be different from the unrealized gain or loss reported in Accumulated other comprehensive loss or the previously reported other-than-temporary impairment charge.

Business Combinations and Goodwill	Business Combinations and Goodwill: In December 2011, we acquired SiliconBlue Technologies Ltd., ("SiliconBlue"), for $63.2 million in cash. Of the total purchase price, $43.9 million was allocated to goodwill, $18.5 million was allocated to intangible assets, and the remaining to net tangible assets acquired. The goodwill and identifiable intangible assets are not deductible for tax purposes. SiliconBlue was consolidated into our financial statements beginning in December 2011. Inventories were recorded at their estimated fair value ("step-up"), which represented an amount equivalent to estimated selling prices less fulfillment costs and a normative selling profit. The step-up of $0.3 million was charged to Acquisition related charges during the six months ended June 30, 2012, approximating the estimated inventory turnover for this particular product. In July 2011, we acquired substantially all of the assets of Rise Technology Development Limited ("Rise"), for $1.0 million in cash. Of the purchase price, $0.9 million was allocated to goodwill and the remaining to net tangible assets acquired. No impairment charges relating to goodwill and intangible assets were recorded for the first six months of 2013 or 2012.

Goodwill and Intangible Assets Disclosure [Abstract]

Intangible Assets and Acquisition Related Charges

Intangible Assets and Acquisition Related Charges:

In connection with our acquisition of SiliconBlue in December 2011, we recorded identifiable intangible assets related to developed technology and customer relationships based on guidance for determining fair value under the provisions of ASC 820. The following table summarizes the details of our total purchased intangible assets (in thousands):



	Weighted Average Amortization Period (in years)	Gross		Accumulated Amortization			Intangible assets, net of amortization June 29, 2013
Developed technology	7	$	10,700	$	(2,357	)	$	8,343
Customer relationships	5.5	7,800		(2,186		)	5,614
Total	6.3	$	18,500	$	(4,543	)	$	13,957

Amortization expense associated with these intangible assets is reported as Acquisition related charges, including the amortization of intangibles in the Consolidated Statements of Operations and Comprehensive Income (Loss) and amounted to $0.7 million in each of the second quarters of the fiscal years ended 2013 and 2012. We expect amortization expense related to these intangible assets to approximate $2.9 million each year in fiscal years 2013 - 2016, $2.2 million in 2017, and $1.5 million in 2018.

Acquisition related charges, including amortization of intangible assets in the Consolidated Statements of Operations and Comprehensive Income (Loss) also include severance and professional fees related to the acquisition, as well as the amortization of the stepped-up value of inventory collectively amounting to $0.0 million and $0.2 million in the second quarter of the fiscal years 2013 and 2012, respectively.

On February 24, 2012, our Board of Directors approved a stock repurchase program pursuant to which up to $20.0 million of outstanding common stock may be repurchased from time to time. The duration of the repurchase program was twelve months. The 2012 program was completed during the first quarter of fiscal 2013, with the repurchase of approximately 0.6 million shares for $2.5 million.

On February 27, 2013, our Board of Directors approved a stock repurchase program pursuant to which up to $20.0 million of outstanding common stock may be repurchased from time to time. The duration of the repurchase program is twelve months. No shares were repurchased under this program during the six months ended June 29, 2013. We expect that all future repurchases will be open market transactions funded from available working capital.

Income Taxes	6 Months Ended
Income Taxes	Jun. 29, 2013
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: For the three months ended June 29, 2013 and June 30, 2012, we recorded an income tax provision of approximately $1.9 million and $10.5 million, respectively. For the six months ended June 29, 2013 and June 30, 2012, we recorded an income tax provision of approximately $2.6 million and $18.4 million, respectively. The income tax provision for the three and six months ended June 29, 2013 represents tax at the federal, state and foreign statutory tax rates adjusted for non-deductible stock compensation, withholding taxes, changes in uncertain tax positions as well as other non-deductible items in foreign jurisdictions. The difference between the U.S. federal statutory tax rate of 35% and our effective tax rate is primarily due to income earned in lower tax rate jurisdictions, for which no U.S. income tax has been provided, as we intend to permanently reinvest these earnings outside of the United States. On December 31, 2011, we began to implement a global tax structure to more effectively align our corporate structure with the geographic business operations including responsibility for sales and manufacturing activities. As part of this tax restructuring, we created new and realigned existing legal entities, completed intercompany sales of rights to intellectual property, inventory and fixed assets across different tax jurisdictions, and implemented cost-sharing and intellectual property licensing and royalty agreements between our U.S. and foreign entities. The global tax structure was completed during the first quarter of 2012 upon the intercompany sale of inventory and fixed assets. During 2012, this inventory was sold to end customers in the ordinary course of business resulting in income before taxes in the United States and a loss before taxes in certain foreign jurisdictions. Because these foreign jurisdictions have 0% income tax rates, we received no tax benefit associated with the losses resulting in a significant foreign rate differential. Taxes were applied to the U.S. income resulting from the intercompany sale based on U.S. statutory rates, offset by deferred tax assets. This resulted in an increase to the effective tax rate and a net income tax provision of $10.5 million and $18.4 million during the three and six months ended June 30, 2012, respectively. We are subject to federal income tax as well as income tax of multiple state and foreign jurisdictions. We are no longer subject to federal, state and local, or foreign income tax examinations for years before 2009, 2008 and 2007, respectively. However, "NOL" and credit carryforwards from all years are subject to examination and adjustments for at least three years following the year in which the attributes are used. We are not currently under examination in any tax jurisdictions. In July 2013, we received notification that the Internal Revenue Service will be commencing an examination of our 2011 federal income tax return. We believe that it is reasonably possible that $0.4 million of unrecognized tax benefits and $0.3 million of associated interest and penalties could be recognized during the next twelve months. The $0.7 million potential change would represent a decrease in unrecognized tax benefits, comprised of items related to federal and state income tax credits claimed and foreign tax filings for years that will no longer be subject to examination under expiring statutes of limitations. We have federal net operating loss carryforwards that expire at various dates between 2023 and 2032. We have state net operating loss carryforwards that expire at various dates from 2013 through 2032. We also have federal and state credit carryforwards, some of which do not expire, with the remainder expiring at various dates from 2013 through 2032. We are paying foreign income taxes, which are reflected in the Provision for income taxes in our Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) and are primarily related to the cost of operating offshore subsidiaries. We are not currently paying federal income taxes and do not expect to pay such taxes until our tax net operating loss and credit carryforwards are fully utilized. We expect to pay a nominal amount of state income tax. We accrue interest and penalties related to uncertain tax positions in the Provision for income taxes. The American Taxpayer Relief Act of 2012, which reinstated the U.S. federal research and development tax credit retroactively from January 1, 2012 through December 31, 2013, was enacted into law during the three months ended March 30, 2013. The tax benefit resulting from the reinstatement of the federal research and development tax credit was offset by a valuation allowance and therefore did not impact our annual effective tax rate.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Restructuring and Related Activities [Abstract]

Restructuring

Restructuring:

In October 2012, our Board of Directors adopted the "2012 restructuring plan." In connection with this restructuring plan, we reduced our headcount by approximately 110 employees and eliminated certain sites, including sites in Pennsylvania and Illinois. In connection with this action, we recorded restructuring charges of less than $0.1 million in the second quarter of fiscal 2013. The 2012 restructuring plan was substantially completed during the first quarter of fiscal 2013.

In 2011, our Board of Directors adopted the "2011 restructuring plan" to more efficiently implement our product development cycle and streamline supply chain activities. In connection with this action, we recorded restructuring charges of approximately $0.1 million during the second quarter of fiscal 2012. The 2011 restructuring plan was completed during the second quarter of 2012.

The following table displays the activity related to the restructuring plans described above (in thousands):

Legal Matters	6 Months Ended
Legal Matters	Jun. 29, 2013
Legal Matters Disclosure [Abstract]
Legal Matters	Legal Matters: On June 11, 2007, a patent infringement lawsuit was filed by Lizy K. John (“John”) against us in the U.S. District Court for the Eastern District of Texas, Marshall Division. In the complaint, John seeks an injunction, unspecified damages, and attorneys' fees and expenses. We filed a request for re-examination of the patent by the U.S. Patent and Trademark Office (“PTO”), which was granted by the PTO. The litigation was stayed pending the results of the re-examination. After the re-examination concluded, the stay was lifted on January 1, 2012, and the lawsuit was transferred by consent of the parties to the Northern District of California. We also filed a request for a second re-examination of the patent, which was granted and is still pending. Discovery is open and proceeding. Trial is scheduled for September 22, 2014. At this stage of the proceedings, we do not have an estimate of the likelihood or the amount of any potential exposure to us. We believe we possess defenses to these claims and intend to vigorously defend this litigation. It is reasonably possible that the actual losses may exceed our accrued liabilities, however, we cannot currently estimate such amount. We are also exposed to certain other asserted and unasserted potential claims. There can be no assurance that, with respect to potential claims made against us, we could resolve such claims under terms and conditions that would not have a material adverse effect on our business, our liquidity or our financial results. Periodically, we review the status of each significant matter and assess its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and a range of possible losses can be estimated, we then accrue a liability for the estimated loss based on the provisions of FASB ASC 450, “Contingencies" (“ASC 450”). Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to pending claims and litigation and may revise estimates. Presently, no accrual has been estimated under ASC 450 for potential losses that may or may not arise from the current lawsuits in which we are involved.

New Accounting Pronouncements

New Accounting Pronouncements:

In February 2013, the FASB issued amendments to the FASB Accounting Standards Codification relating to the reporting of reclassifications out of accumulated other comprehensive income. The amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. We were required to adopt these amendments in the first quarter of fiscal 2013.

In June 2013, the Emerging Issues Task Force ("EITF") reached consensus on ASU 2013-11 Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The consensus requires companies to present the unrecognized tax benefit as a reduction of the Deferred tax asset for a Net Operating Loss ("NOL") or similar tax loss, or tax credit carryforward rather than as a liability when the uncertain tax position would reduce the NOL or other carryforward under the tax law. We early adopted this requirement in June of 2013 with retrospective application as permitted by the standard. Amounts presented in prior periods have been reclassified to conform
