Note 2 - Net Income (Loss) Per Share

Our calculation of the diluted share count includes the number of shares from our equity awards with market conditions or performance conditions that would be issuable under the terms of such awards at the end of the reporting period. For equity awards with a market condition, the maximum number of shares issuable are included in the diluted share count as of January 2, 2021, as the market condition would have been achieved at the highest level of vesting if measured as of the end of the reporting period. For equity awards with a performance condition, no shares are included in the diluted share count as of January 2, 2021, as vesting of future tranches of these awards is contingent upon achievement of the performance condition over two consecutive trailing four-quarter periods, which has not yet been achieved. See "Note 10 - Stock-Based Compensation Plans" to our consolidated financial statements for further discussion of our equity awards with market or performance conditions.

A summary of basic and diluted Net income (loss) per share is presented in the following table:

	*Year Ended*
	*January 2,*		*December 28,*		*December 29,*
(in thousands, except per share data)	*2021*		*2019*		*2018*

Shares used in basic Net income (loss) per share		135,220		132,471		126,564
Dilutive effect of stock options, RSUs, ESPP shares, and equity awards with a market condition or performance condition		6,056		4,803		—
Shares used in diluted Net income (loss) per share		141,276		137,274		126,564

Diluted Net income (loss) per share	$	0.34	$	0.32	$	(0.21	)

The computation of diluted Net income (loss) per share excludes the effects of stock options, RSUs, ESPP shares, and equity awards with a market condition or performance condition that are antidilutive, aggregating approximately the following number of shares:

Contract balances

Our contract assets relate to our rights to consideration for licenses and royalties due to us as a member of the HDMI consortium, with collection dependent on events other than the passage of time, such as collection of licenses and royalties from customers by the HDMI licensing agent. The balance results primarily from the amount of estimated revenue related to HDMI that we have recognized to date, but which has not yet been collected by the agent. Contract assets are recorded in Prepaid expenses and other current assets in our Consolidated Balance Sheets.

The following table summarizes activity during the periods presented:

(In thousands)
Contract assets as of December 29, 2018	$	9,143
Revenues recorded during the period		17,356
Transferred to Accounts receivable or collected		(20,930	)
Contract assets as of December 28, 2019	$	5,569
Revenues recorded during the period		15,860
Transferred to Accounts receivable or collected		(15,818	)
Contract assets as of January 2, 2021	$	5,611

Contract liabilities are included in Accrued expenses on our Consolidated Balance Sheets. The following table summarizes activity during the periods presented:

(In thousands)
Contract liabilities as of December 29, 2018	$	1,614
Accruals for estimated future stock rotation and scrap returns		5,763
Less: Release of accruals for recognized stock rotation and scrap returns		(5,064	)
Contract liabilities as of December 28, 2019	$	2,313
Accruals for estimated future stock rotation and scrap returns		5,976
Less: Release of accruals for recognized stock rotation and scrap returns		(5,221	)
Contract liabilities as of January 2, 2021	$	3,068

The impact to revenue in fiscal years 2020 and 2019 from the release of accruals for recognized stock rotation and scrap returns was offset by the processing of return merchandise authorizations totaling $6.1 million and $5.0 million, respectively, yielding a net revenue decrease of approximately $0.9 million and a net revenue increase of approximately $0.1 million, respectively.

Note 8 - Leases

Our facilities for corporate offices, sales offices, research and development facilities, storage facilities, and a data center, are all leased under operating leases, which expire at various times through 2027. Our leases have remaining lease terms of 1 to 8 years, some of which include options to extend for up to 5 years, and some of which include options to terminate within 1 year. The weighted-average remaining lease term was 4.6 years and the weighted-average discount rate is 6.5% as of January 2, 2021. We recorded fixed operating lease expense of $7.6 million and $7.7 million, respectively, for fiscal 2020 and 2019. Rental expense under the previous guidance for operating leases was $8.3 million for fiscal 2018.

On February 14, 2020, our Board of Directors approved a stock repurchase program pursuant to which up to $40.0 million of outstanding common stock could be repurchased from time to time. The duration of the repurchase program was twelve months. Under this program during the fourth quarter of fiscal 2020, approximately 0.4 million shares were repurchased for $15.0 million, or an average price paid per share of $38.98. All repurchased shares were retired by the end of the 2020 fiscal year. All repurchases were open market transactions funded from available working capital.

ASC 740, “Income Taxes”, provides for the recognition of deferred tax assets if realization of these assets is more-likely-than-not. We evaluate both positive and negative evidence to determine if some or all of our deferred tax assets should be recognized on a quarterly basis.

Through January 2, 2021, we continued to evaluate the valuation allowance position in the United States and concluded that we should maintain a full valuation allowance against the net federal and state deferred tax assets. In making this evaluation, we exercised significant judgment and considered estimates about our ability to generate revenue and taxable profits sufficient to offset expenditures in future periods within the United States. We will continue to evaluate both positive and negative evidence in future periods to determine if we will realize the net deferred tax assets. We don't have a valuation allowance in any foreign jurisdictions as we have concluded it is more likely than not that we will realize the net deferred tax assets in future periods.

The components of our net deferred tax assets are as follows:

At January 2, 2021, we had U.S. federal net operating loss ("NOL") carryforwards (pretax) of approximately $359.5 million that expire at various dates between 2021 and 2037. We had state NOL carryforwards (pretax) of approximately $147.6 million that expire at various dates from 2021 through 2037. We also had federal and state credit carryforwards of $51.7 million and $64.9 million, respectively. Of the $64.9 million state credit carryforwards, $64.5 million do not expire. The federal and remaining state credits expire at various dates from 2021 through 2040.

Future utilization of federal and state net operating losses and tax credit carry forwards may be limited if cumulative changes to ownership exceed 50% within any three-year period. If there is a significant change in ownership, future tax attribute utilization may be restricted and an allowance will be recorded against NOL carryforwards and/or R&D credits to reflect the limitation.

Foreign earnings may be subject to withholding taxes in local jurisdictions if they are distributed and repatriated in the United States. At January 2, 2021, U.S. income taxes and foreign withholding taxes were not provided for on a cumulative total of approximately $3.1 million of the undistributed earnings of our Chinese subsidiary. We intend to reinvest these earnings indefinitely.

At January 2, 2021, our unrecognized tax benefits associated with uncertain tax positions were $55.7 million, of which $53.6 million, if recognized, would affect the effective tax rate, subject to valuation allowance. As of January 2, 2021, interest and penalties associated with unrecognized tax benefits were $9.1 million, which are not reflected in the table below.

The following table summarizes the changes to unrecognized tax benefits for the fiscal years presented:

	(in thousands)
Balance at December 30, 2017	$	58,377
Additions based on tax positions related to the current year		389
Additions based on tax positions of prior years		759
Reduction for tax positions of prior years		(5	)
Reduction as a result of lapse of applicable statute of limitations		(1,235	)
Balance at December 29, 2018		58,285
Additions based on tax positions related to the current year		238
Additions based on tax positions of prior years		1,084
Reductions for tax positions of prior years		(213	)
Reduction as a result of lapse of applicable statute of limitations		(2,432	)
Balance at December 28, 2019		56,962
Additions based on tax positions related to the current year		548
Additions based on tax positions of prior years		628
Reductions for tax positions of prior years		—
Reduction as a result of lapse of applicable statute of limitations		(2,401	)
Balance at January 2, 2021	$	55,737

The balance of the unrecognized tax benefit at December 30, 2017 included in the table above summarizing the changes to the unrecognized tax benefit has been updated from $44,832 thousand to $58,377 thousand. Additionally, the amounts in this table for Additions based on tax positions of prior years during 2018 and 2019 have been updated from $19 thousand and $334 thousand to $759 thousand and $1,084 thousand, respectively.

Our liability for uncertain tax positions (including penalties and interest) was $22.3 million and $24.6 million at January 2, 2021 and December 28, 2019, respectively, and is recorded as a component of Other long-term liabilities on our Consolidated Balance Sheets. The remainder of our uncertain tax position exposure of $42.5 million is netted against deferred tax assets.

At January 2, 2021, it is reasonably possible that $2.7 million of unrecognized tax benefits and $0.4 million of associated interest and penalties could be recognized during the next twelve months. The $3.1 million potential change would represent a decrease in unrecognized tax benefits, comprised of items related to tax filings for years that will no longer be subject to examination under expiring statutes of limitations.

The years that remain subject to examination are 2017 for federal income taxes, 2016 for state income taxes, and 2013 for foreign income taxes, including years ending thereafter. However, to the extent allowed by law, the tax authorities may have the right to examine prior periods where net operating losses or tax credits were generated and carried forward, and make adjustments up to the amount of the net operating losses or credit carryforward amount.

Our Philippines 2016 and 2017 and Israeli 2013 through 2017 income tax returns are currently under examination. We are not under examination in any other jurisdiction.

We are not currently paying U.S. federal income taxes and do not expect to pay such taxes until we fully utilize our tax NOL and credit carryforwards. We expect to pay a nominal amount of state income tax. We are paying foreign income and withholding taxes, which are reflected in income tax expense in our Consolidated Statements of Operations and are primarily related to the cost of operating offshore activities and subsidiaries. We accrue interest and penalties related to uncertain tax positions in income tax expense.

In response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (CARES Act) was signed into law in March 2020. The CARES Act lifts certain deduction limitations originally imposed by the Tax Cuts and Jobs Act of 2017 (2017 Tax Act). The CARES Act eliminates the 80% of taxable income limitations by allowing corporate entities to fully utilize NOL carryforwards to offset taxable income in 2018, 2019 or 2020. Taxpayers may generally deduct interest up to the sum of 50% of adjusted taxable income plus business interest income (30% limit under the 2017 Tax Act) for tax years beginning January 1, 2019 and 2020. The CARES Act makes qualified improvement property generally eligible for 15-year cost-recovery and 100% bonus depreciation. In addition, the CARES Act allows companies to defer making certain payroll tax payments until future years. With the enactment of the CARES Act, the Company does not expect a financial statement impact from income taxes. The Company has not recorded any income tax expense or benefit relate to the Act for the year ended January 2, 2021.

Compensation and Employee Benefit Plans [Text Block]

Note 13 - Employee Benefit Plans

Qualified Investment Plan

In 1990, we adopted a 401(k) tax-deferred savings plan, which provides all employees in the United States who meet certain eligibility requirements with an opportunity to accumulate funds for retirement. Participants may contribute up to the amount allowable as a deduction for federal income tax purposes. The plan does not allow investments in the Company's common stock. The plan allows for the Company to make discretionary matching contributions in cash. We recorded matching contributions of approximately $2.4 million, $0.8 million, and $0.6 million in fiscal years 2020, 2019, and 2018, respectively.

Cash Incentive Plans

For 2020, 2019, and 2018, the Board of Directors of the Company, upon the recommendation of the Compensation Committee, approved the Cash Incentive Plan (the “Cash Plans”) for the respective fiscal year. The chief executive officer, other executive officers, and other members of senior management, including vice presidents and director-level employees, together with all other employees of the Company not on the Company's sales incentive plan are eligible to participate in the Cash Plans. Under the Cash Plans, individual cash incentive payments for the eligible employees will be based both on Company financial performance, as measured by achievement of operating income (before incentive plan accruals) and revenue goals within specified ranges established by the Compensation Committee, and Company performance, as measured by the achievement of personal management objectives. The Compensation Committee determines the performance of the chief executive officer, the chief financial officer and other participants based on the achievement of the management objectives established by the Compensation Committee during the first quarter of the respective fiscal year. We recorded approximately $7.9 million, $5.8 million, and $5.9 million of expense under the Cash Plans in fiscal 2020, 2019, and 2018, respectively.

Significant Accounting Policies (Policies)

12 Months Ended

Jan. 02, 2021

Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

The accompanying Consolidated Financial Statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles ("U.S. GAAP"). They include the accounts of Lattice and its subsidiaries after the elimination of all intercompany balances and transactions.

Use of Estimates, Policy [Policy Text Block]

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments affecting the amounts reported in our consolidated condensed financial statements and the accompanying notes. The actual results that we experience may differ materially from our estimates.

Certain prior year balances have been reclassified to conform to the current year’s presentation.

Fiscal Period, Policy [Policy Text Block]

Fiscal Reporting Periods

We report based on a 52 or 53-week fiscal year ending on the Saturday closest to December 31. Our fiscal 2020 was a 53-week year that ended on January 2, 2021. Our fiscal 2019, and 2018 were 52-week years that ended on December 28, 2019 and December 29, 2018, respectively. All references to quarterly or annual financial results are references to the results for the relevant fiscal period.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Concentrations of Risk

Potential exposure to concentrations of risk may impact revenue, accounts receivable, and supply of wafers for our new products.

Distributors have historically accounted for a significant portion of our total revenue. Our two largest distributor groups, the Weikeng Group ("Weikeng") and Arrow Electronics, Inc. ("Arrow"), each account for more than 10% of our total revenue and our net accounts receivable. Revenue attributable to distributors as a percentage of total revenue is presented in the following table:

	*Year Ended*
	*January 2, 2021*			*December 28, 2019*			*December 29, 2018*
Weikeng Group		35	%		30	%		25	%
Arrow Electronics Inc.		25			25			29
Other distributors		23			27			29
Revenue attributable to distributors		83	%		82	%		83	%

At January 2, 2021 and December 28, 2019, Weikeng accounted for 47% and 38%, respectively, and Arrow accounted for 45% and 40%, respectively, of net accounts receivable.

Concentration of credit risk with respect to accounts receivable is mitigated by our credit and collection process including active management of collections, credit limits, routine 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.

We rely on a limited number of foundries for our wafer purchases. We seek to mitigate the concentration of supply risk by establishing, maintaining and managing multiple foundry relationships; however, certain of our products are sourced from a single foundry and changing from one foundry to another can have a significant cost, or create delays in production or shipments, among other factors.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

We consider all investments that are readily convertible into cash and that 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, which approximates fair value. Deposits with financial institutions at times exceed Federal Deposit Insurance Corporation insurance limits.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Exchange and Translation of Foreign Currencies

While our revenues and the majority of our expenses are denominated in U.S. dollars, we also have international subsidiaries and branch operations that conduct some transactions in currencies that differ from the functional currency of that entity. Gains or losses from foreign exchange rate fluctuations on balances denominated in currencies that differ from the functional currencies are reflected in Other expense, net.

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 (See our Consolidated Statements of Stockholders' Equity).

Revenue from Contract with Customer [Policy Text Block]

Revenue Recognition

Under the terms of ASC 606, "Revenue from Contracts with Customers", we recognize revenue when we satisfy performance obligations as evidenced by the transfer of control of our products or services to customers. For sales to distributors, we have concluded that our contracts are with the distributor, rather than with the distributor’s end customer, as we hold a contract bearing enforceable rights and obligations only with the distributor. The majority of our revenue is derived from product sales. We consider customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. For each contract, we consider our promise to transfer each distinct product to be the identified performance obligations. Revenue for product sales is recognized at the time of product shipment, as determined by the agreed upon contract shipping terms.

Our Licensing and services revenue is comprised of revenue from our intellectual property ("IP") core licensing activity, patent monetization activities, design services, and royalty and adopter fee revenue from our standards activities. These activities are complementary to our product sales and help us to monetize our IP associated with our technology and standards. We consider licensing arrangements with our customers and agreements with the standards consortia of which we are a member to be the contract. For each contract, we consider the promise to deliver a license that grants the customer the right to use the IP, as well as any professional services provided under the contract, as distinct performance obligations. We recognize license revenue at the point in time that control of the license transfers to the customer, which is generally upon delivery, or as usage occurs.

We measure revenue based on the amount of consideration we expect to be entitled to in exchange for products or services. Variable consideration is estimated and reflected as an adjustment to the transaction price. We determine variable consideration, which consists primarily of various sales price concessions, by estimating the most likely amount of consideration we expect to receive from the customer based on an analysis of historical rebate claims over a period of time considered adequate to account for current pricing and business trends. Sales rebates earned by customers are offset against their receivable balances. Rebates earned by customers when they do not have outstanding receivable balances are recorded within Accrued expenses. Licensing and services revenue includes HDMI and MHL standards revenue, as well as certain IP licenses, include variable consideration in the form of usage-based royalties.

We generally provide an assurance warranty that our products will substantially conform to the published specifications for twelve months from the date of shipment. In some cases, the warranty period may be longer than twelve months. We do not separately price or sell the assurance warranty. Our liability is limited to either a credit equal to the purchase price or replacement of the defective part. Under the practical expedient provided by ASC 340, we generally expense sales commissions when incurred because the amortization period would be less than one year. We record these costs within Selling, general, and administrative expenses. Substantially all of our performance obligations are satisfied within twelve months.

Inventory, Policy [Policy Text Block]

Inventories and Cost of Revenue

Inventories are stated at the lower of actual cost (determined using the first-in, first-out method) or net realizable value. We review and set standard costs quarterly to approximate current actual manufacturing costs. Our manufacturing overhead standards for product costs are calculated assuming full absorption of actual spending over actual costs. The valuation of inventory requires us to estimate excess or obsolete inventory. Material assumptions we use to estimate necessary inventory carrying value adjustments can be unique to each product and are based on specific facts and circumstances. In determining provisions for excess or obsolete products, we consider assumptions such as changes in business and economic conditions, projected customer demand for our products, and changes in technology or customer requirements. The creation of such provisions results in a write-down of inventory to net realizable value and a charge to Cost of revenue. Lower of cost or net realizable value is based on assumptions such as recent historical sales activity and selling prices, as well as estimates of future selling prices. Shipping and handling costs are included in Cost of revenue in our Consolidated Statements of Operations.

Property, Plant and Equipment, Policy [Policy Text Block]

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related assets, generally three to five years for equipment and software, and one to three years for tooling. Leasehold improvements are amortized over the shorter of the non-cancelable lease term or the estimated useful life of the assets. We capitalize costs for the fabrication of masks used by our foundry partners to manufacture our products. The capitalized mask costs begin depreciating to Cost of revenue once the products go into production, and depreciation is straight-lined over a three-year period, which is the expected useful life of the mask. Upon disposal of property and equipment, the accounts are relieved of the costs and related accumulated depreciation and amortization, and resulting gains or losses are reflected in the Consolidated Statements of Operations for recognized gains and losses. Repair and maintenance costs are expensed as incurred.

Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]

Impairment of Long-Lived Assets

Long-lived assets, which consist primarily of property and equipment, amortizable intangible assets, and right-of-use assets, are carried on our financial statements based on their cost less accumulated depreciation or amortization. We monitor the carrying value of our long-lived assets for potential impairment and test the recoverability of such assets whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. These events or changes in circumstances, including management decisions pertaining to such assets, are referred to as impairment indicators. If an impairment indicator occurs, we perform a test of recoverability by comparing the carrying value of the asset group to its undiscounted expected future cash flows. If the carrying values are in excess of undiscounted expected future cash flows, we measure any impairment by comparing the fair value of the asset group to its carrying value. Fair value is generally determined by considering (i) internally developed discounted projected cash flow analysis of the asset group; (ii) actual third-party valuations; and/or (iii) information available regarding the current market for similar asset groups. If the fair value of the asset group is determined to be less than the carrying amount of the asset group, an impairment in the amount of the difference is recorded in the period that the impairment indicator occurs and is included in our Consolidated Statements of Operations. Estimating future cash flows requires significant judgment and projections may vary from the cash flows eventually realized, which could impact our ability to accurately assess whether an asset has been impaired. There has been no occurrence of events to date that would trigger an impairment analysis of property and equipment. The results of our assessments of amortizable intangible assets are detailed in "Note 9 - Intangible Assets."

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]

Valuation of Goodwill

Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is not amortized, but is instead tested for impairment annually during the fourth quarter and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. When evaluating whether goodwill is impaired, we make a qualitative assessment to determine if it is more likely than not that the reporting unit's fair value is less than the carrying amount. If the qualitative assessment determines that it is more likely than not that the fair value is less than the carrying amount, the fair value of the reporting unit is compared with its carrying value (including goodwill). If the fair value of the reporting unit is less than its carrying value, then goodwill impairment exists for the reporting unit. The impairment loss, if any, is recognized for the amount by which the carrying value exceeds the fair value. If the fair value of the reporting unit exceeds its carrying value, no further impairment analysis is needed. For purposes of testing goodwill for impairment, we currently operate as a single reporting unit.

No impairment charges relating to goodwill were recorded for either fiscal 2020 or 2019, as no indicators of impairment were present. We determined that the strategic decision to discontinue our millimeter wave business in the second quarter of 2018 constituted a triggering event related to goodwill, and we evaluated our goodwill balance as of June 30, 2018. We concluded that goodwill was not impaired, and no impairment charges relating to goodwill were recorded for fiscal 2018.

Lessee, Leases [Policy Text Block]

Leases

We account for leases under the terms of ASC 842, "Leases," which requires lessees to record assets and liabilities on the balance sheet for all leases with terms longer than 12 months. Upon adoption, we elected the "package of practical expedients" that would allow us to carryforward our historical lease classifications, not reassess historical contracts to determine if they contain leases, and not reassess the initial direct costs for any existing leases. We also elected the practical expedient to not separate lease and non-lease components, which we applied to all asset classes. Concurrent with our adoption of Topic 842, we early adopted ASU 2019-01, Leases (Topic 842): Codification Improvements, which granted disclosure relief for interim periods during the year in which a company adopted Topic 842.

Right-of-use ("ROU") assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized on the commencement date of the lease based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we determine the present value of lease payments using an incremental borrowing rate based on information from our commercial bank for an equivalent borrowing and term in the respective region as of the lease commencement date. At inception, we determine if an arrangement is a lease, if it includes options to extend or terminate the lease, and if it is reasonably certain that we will exercise the options. Lease cost, representing lease payments over the term of the lease and any capitalizable direct costs less any incentives received, is recognized on a straight-line basis over the lease term as lease expense. We have operating leases for corporate offices, sales offices, research and development facilities, storage facilities, and a data center.

The exercise of lease renewal options is at our sole discretion. When deemed reasonably certain of exercise, the renewal options are included in the determination of the lease term and lease payment obligation, respectively. For our leases that contain variable lease payments, residual value guarantees, or restrictive covenants, we have concluded that these inputs are not significant to the determination of the ROU asset and lease liability.

Research and Development Expense, Policy [Policy Text Block]

Research and Development

Research and development expenses include costs for compensation and benefits, engineering wafers, depreciation, licenses, and outside engineering services. These expenditures are for the design of new products, intellectual property cores, processes, packaging, and software solutions. Research and development costs are generally expensed as incurred, with certain licensed technology agreements capitalized as intangible assets and amortized to Research and development expense over their estimated useful lives.

Costs Associated with Exit or Disposal Activities or Restructurings, Policy [Policy Text Block]

Restructuring Charges

Expenses associated with exit or disposal activities are recognized when incurred under ASC 420, “Exit or Disposal Cost Obligations,” for everything except severance expenses and vacated leased facilities. Because we have a history of paying severance benefits, the cost of severance benefits associated with a restructuring plan is recorded when such costs are probable and the amount can be reasonably estimated in accordance with ASC 712, “Compensation - Nonretirement Postemployment Benefits.” When leased facilities are vacated, the amount of any ROU asset impairment is calculated in accordance with ASC 360, "Property, Plant, and Equipment" and recorded as a part of restructuring charges. Expenses from other exit or disposal activities, including the cancellation of software contracts and engineering tools or the abandonment of long-lived assets, is recorded as a part of restructuring charges.

Income Tax, Policy [Policy Text Block]

Accounting for Income Taxes

Our provision for income tax is comprised of our current tax liability and changes in deferred tax assets and liabilities. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements using enacted tax rates and laws that will be in effect when the difference is expected to reverse. Valuation allowances are provided to reduce deferred tax assets to an amount that in management’s judgment is more-likely-than-not to be recoverable against future taxable income. The determination of a valuation allowance and when it should be released requires complex judgment.

In assessing the ability to realize deferred tax assets, we evaluate both positive and negative evidence that may exist and consider whether it is more-likely-than-not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Any adjustment to the net deferred tax asset valuation allowance is recorded in the Consolidated Statements of Operations for the period that the adjustment is determined to be required.

Our income tax calculations are based on application of the respective U.S. federal, state or foreign tax law. Our tax filings, however, are subject to audit by the relevant tax authorities. Accordingly, we recognize tax liabilities based upon our estimate of whether, and the extent to which, additional taxes will be due when such estimates are more-likely-than-not to be sustained. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. To the extent the final tax liabilities are different than the amounts originally accrued, the increases or decreases as well as any interest or penalties are recorded as income tax expense or benefit in the Consolidated Statements of Operations.

Share-based Payment Arrangement [Policy Text Block]

Stock-Based Compensation

We estimate the fair value of share-based awards consistent with the provisions of ASC 718, “Compensation - Stock Compensation.” We value RSUs using the closing market price on the date of grant, and we value stock options using the Black-Scholes option pricing model. We have also granted RSUs with a market condition to certain executives. The awards with a market condition have a three-year vesting period and vest between 0% and 250% of the target amount, based on the Company's relative Total Shareholder Return ("TSR") over the measurement period compared to the TSR of a component of companies of the PHLX Semiconductor Sector Index for awards granted in fiscal 2018 and 2019 or the Russell 2000 index for awards granted in 2020. TSR is measured as stock price appreciation in the performance period. We have also granted RSUs with a performance condition to our President and Chief Executive Officer, which will vest and become payable based upon the Company’s generating specified “adjusted” EBITDA levels on a trailing four-quarter basis in any two consecutive trailing four-quarter periods. We assess the probability of achieving the performance condition on a quarterly basis. We valued the RSUs with a performance condition using the market price on the date of grant.

Segment Reporting, Policy [Policy Text Block]

Segment Information

As of January 2, 2021, we had one operating segment: the core Lattice business, which includes semiconductor devices, evaluation boards, development hardware, and related intellectual property licensing, services, and sales. Our chief operating decision maker is the Chief Executive Officer, who reviews operating results and financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance.

New Accounting Pronouncements, Policy [Policy Text Block]

New Accounting Pronouncements

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which adds new guidance for accounting for tax law changes, year-to-date losses in interim periods, and determining how to apply the income tax guidance to franchise taxes that are partially based on income, as well as other changes to simplify accounting for income taxes. The ASU is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Entities may early adopt the ASU in any interim period for which financial statements have not yet been issued (or made available for issuance). We are currently assessing the impact of ASU 2019-12 on our consolidated financial statements and related disclosures.

Notes to Financial Statements
Contingencies Disclosure [Text Block]	Note 14 - Contingencies Legal Matters On or about December 19, 2018, Steven A.W. De Jaray, Perienne De Jaray and Darrell R. Oswald (collectively, the “Plaintiffs”) commenced an action against the Company and several unnamed defendants in the Multnomah County Circuit Court of the State of Oregon, in connection with the sale of certain products by the Company to the Plaintiffs in or around 2008. The Plaintiffs allege that we violated The Lanham Act, engaged in negligence and fraud by failing to disclose to the Plaintiffs the export-controlled status of the subject parts. The Plaintiffs seek damages of $138 million, treble damages, and other remedies. In January 2019, we removed the action to the United States District Court for the District of Oregon. At this stage of the proceedings, we do not have an estimate of the likelihood or the amount of any potential exposure to the Company; however, we believe that these claims are without merit and intend to vigorously defend the action. From time to time, we are exposed to certain asserted and unasserted potential claims. 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. 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.
