Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 1—Summary of Significant Accounting Policies ​ Basis of Presentation ​ Netlist, Inc. and its wholly owned subsidiaries (collectively the “Company”, “Netlist,” “we,” “us,” or “our”) provides high-performance memory solutions to enterprise customers in diverse industries. Our products in various capacities and form factors and the line of custom and specialty memory products bring industry-leading performance to server and storage appliance customers and cloud service providers. We license our portfolio of intellectual property including patents, in server memory, hybrid memory and storage class memory, to companies that implement our technology. We operate in one reportable segment, which is the design and manufacture of high-performance memory subsystems for the server, high-performance computing and communications markets. ​ The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts of Netlist, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, net sales and expenses. Actual results may differ materially from those estimates. We have evaluated events occurring subsequent to December 31, 2022, through the filing date of this Annual Report on Form 10-K and concluded that there were no events that required recognition and disclosures, other than those discussed elsewhere in the notes hereto. Certain prior period amounts have been reclassified to conform to the current period’s presentation. ​ Our fiscal year is the 52- or 53-week period that ends on the Saturday nearest to December 31. Our fiscal year 2022 ended on December 31, 2022, fiscal year 2021 ended on January 1, 2022, and fiscal year 2020 ended on January 2, 2021. All fiscal years presented in this Form 10-K, except fiscal year 2020, included 52 weeks. Additionally, all quarters, except the fourth quarter of 2020, included 13 weeks. Fiscal year 2020 included 53 weeks, with a 14 -week fourth quarter. Unless otherwise stated, references to particular years, quarters, months and periods refer to our fiscal years ended in January or December and the associated quarters, months and periods of those fiscal years. ​ Recently Adopted Accounting Standards ​ In the first quarter of 2022, we adopted the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity . This ASU amends the guidance on convertible instruments and the derivatives scope exception for contracts in an entity's own equity, and also improves and amends the related earnings per share guidance for both Subtopics. The adoption of this ASU did not have an impact on the Company’s condensed consolidated financial statements as the Company paid off its convertible debt in December 2021. ​ Revenue Recognition ​ Product Revenue ​ Revenue is recognized when control is transferred to customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods and services. Revenue recognition is evaluated through the five steps outlined within the accounting guidance. Substantially all of our product sales relate to products sold at a point in time through ship-and-bill performance obligations. At contract inception, an assessment of the goods and services promised in the contracts with customers is performed and a performance obligation is identified for each distinct promise to transfer to the customer a good or service (or bundle of goods or services). To identify the performance obligations, we consider all of the goods or services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. Contracts with customers are comprised of customer purchase orders, invoices (including our standard terms and conditions) and written contracts. ​ License Revenue ​ For licenses of technology, recognition of revenue is dependent upon whether we have delivered rights to the technology, and whether there are future performance obligations under the contract. In some instances, the license agreements call for future events or activities to occur in order for milestone amounts to become due from the customer. The terms of such agreements include payments to us of one or more of the following: non-refundable upfront fees and royalties on net sales of licensed products. Historically, these license agreements have not included other future performance obligations for us once the license has been transferred to the customer. ​ Revenue from non-refundable upfront payments is recognized when the license is transferred to the customer and we have no other performance obligations. ​ Performance Obligations ​ Net product sales and related cost of sales are primarily the result of promises to transfer products to customers. For performance obligations related to substantially all of the ship-and-bill products, control transfers at a point in time when title transfers upon shipment of the product to the customer, and for some sales, control transfers when title is transferred at time of receipt by the customer. Once a product has shipped or has been delivered, the customer is able to direct the use of, and obtain substantially all of the remaining benefits from, the asset. We consider control to have transferred upon shipment or delivery, because we have a present right to payment at that time, the customer has legal title to the asset, we have transferred physical possession of the asset, and the customer has the significant risks and rewards of ownership of the asset. ​ Amounts billed to our customers for shipping and handling are recorded in net sales. Shipping and handling costs incurred by us are included in cost of sales in the accompanying consolidated statements of operations. ​ Significant Payment Terms ​ For ship-and-bill type contracts with customers, the invoice states the final terms of the sale, including the description, quantity, and price of each product purchased. Payment terms are typically due within 30 days after delivery but, in limited instances, can range up to 90 days after delivery. Accordingly, our contracts with customers do not include a significant financing component. ​ Variable Consideration ​ Our revenue generating activities include variable consideration which is recorded as a reduction of the transaction price based upon expected amounts at the time revenue for the corresponding product sale is recognized. Common forms of variable consideration include limited rights of return for up to 30 days, except for sales of excess component inventories, which contain no right-of-return privileges and volume rebates for meeting established sales targets. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the anticipated performance and all information (historical, current and forecasted) that is reasonably available. ​ Returns for products sold are estimated using the expected value method and are recorded as a reduction in reported revenues at the time of sale based upon historical product return experience and is adjusted for known trends to arrive at the amount of consideration to which we expect to receive. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. ​ ​ ​ Contract Assets and Liabilities ​ We continually evaluate whether the revenue generating activities and advanced payment arrangements with customers result in the recognition of contract assets or liabilities. Generally, we do not have material amounts of contract assets since revenue is recognized as control of goods is transferred or as services are performed. As of January 1, 2022 and December 31, 2022, there were no contract liabilities. ​ Warranties ​ We offer standard product warranties generally ranging from one ​ Cash and Cash Equivalents ​ Cash and cash equivalents consist of cash and short-term investments with original maturities of three months or less. ​ Restricted Cash ​ Our restricted cash consists of cash to secure standby letters of credit (see Note 3). ​ Fair Value Measurements ​ Certain assets and liabilities are accounted for at fair value. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in one of those three levels based on the lowest level input that is significant to the fair value measurement in its entirety. ​ ● Level 1 – inputs are based on unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access. An active market is defined as a market in which transactions for the assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis. ● Level 2 – inputs are based on quoted prices of similar instruments in active markets, quoted prices for identical or similar instruments in market that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. ● Level 3 – inputs are generally unobservable inputs for the asset or liability, which are typically based on management’s estimates of assumptions that market participants would use in pricing the assets and liabilities. The fair values are therefore determined using model-based techniques, including option pricing models and discounted cash flow models. ​ Our financial instruments consist principally of cash and cash equivalents, restricted cash, a revolving line of credit and note payable. Cash equivalents consist of short-term investments with original maturities of three months or less and restricted cash consists of cash to secure standby letters of credit (see Note 3). The carrying value of these instruments approximates their fair value due to their short-term nature. The fair value of the revolving line of credit and the note payable is estimated by using current applicable rates for similar instruments as of the balance sheet date and an assessment of the credit rating. The carrying values of the revolving line of credit as of December 31, 2022 and January 1, 2022 and the note payable as of December 31, 2022 and January 1, 2022 approximate fair value because the interest rate yield is near current market rates for comparable debt instruments. ​ Accounts Receivable, net ​ We extend credit to our customers. An allowance for doubtful accounts is maintained for estimated losses resulting from the inability of our customers to make required payments. We specifically analyze the age of customer balances, historical bad debt experiences, customer creditworthiness and changes in customer payment terms when making estimates of the collectability of our accounts receivable balances. If we determine that the financial condition of any of our customers has deteriorated, whether due to customer specific or general economic issues, an increase in the allowance may be made. After all attempts to collect a receivable have failed, the receivable is written off. ​ Concentration of Credit Risk ​ Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents, and accounts receivable. We invest our cash equivalents primarily in money market mutual funds. Cash equivalents are maintained with high quality institutions, the composition and maturities of which are regularly monitored by management. At times, deposits held with financial institutions may exceed the amount of insurance provided by the Federal Deposit Insurance Corporation and the Securities Investor Protection Corporation. ​ ​ Inventories ​ Inventories are valued at the lower of cost or the net realizable value. Cost is determined on an average cost basis which approximates actual cost on a first-in, first-out basis and includes raw materials, labor and manufacturing overhead. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. We evaluate inventory balances for excess quantities and obsolescence on a regular basis by analyzing estimated demand, inventory on hand, sales levels and other information and reduce inventory balances to net realizable value for excess and obsolete inventory based on this analysis. At the point of the write-down recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. ​ Property and Equipment ​ Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives, which generally range from three ​ Impairment of Long-Lived Assets ​ We evaluate the recoverability of the carrying value of long-lived assets held and used by us in our operations for impairment on at least an annual basis or whenever events or changes in circumstances indicate that their carrying value may not be recoverable. When such factors and circumstances exist, we compare the projected undiscounted future net cash flows associated with the related asset or group of assets over their estimated useful lives against their respective carrying amount. These projected future cash flows may vary significantly over time as a result of increased competition, changes in technology, fluctuations in demand, consolidation of our customers and reductions in average sales prices. If the carrying value is determined not to be recoverable from future operating cash flows, the asset is deemed impaired and an impairment loss is recognized to the extent the carrying value exceeds the estimated fair value of the asset. The fair value of the asset or asset group is based on market value when available, or when unavailable, on discounted expected cash flows. Management believes there is no impairment of long-lived assets as of December 31, 2022 and January 1, 2022. ​ Leases ​ We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, accrued expenses and other current liabilities, and operating lease liabilities on our consolidated balance sheets. Finance leases are included in property and equipment, accrued expenses and other current liabilities, and other liabilities in our consolidated balance sheets. ​ 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 at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. ​ We have lease agreements with lease and non-lease components, which are accounted for as a single lease component. We do not present short-term leases on the balance sheet, as those leases have a lease term of twelve months or less at inception and do not contain purchase options or renewal terms that we are reasonably certain to exercise. ​ Stock-Based Compensation ​ Stock-based awards are comprised principally of stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”). Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as an expense over the requisite service period, which is the vesting period, on a straight-line basis, net of estimated forfeitures. We use the Black-Scholes option pricing model to determine the grant date fair value of stock options. The model requires us to estimate the expected volatility and expected term of the stock options, which are highly complex and subjective variables. The expected volatility is based on the historical volatility of our common stock. The expected term is computed using the simplified method as our best estimate given our lack of actual exercise history. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the expected term of the grant effective as of the date of the grant. The expected dividend assumption is based on our history and management’s expectation regarding dividend payouts. The grant-date fair value of RSAs and RSUs equals the closing price of our common stock on the grant date. ​ Income Taxes ​ Deferred income tax assets and liabilities are recognized for temporary differences between the financial statement carrying amounts of assets and liabilities and the amounts that are reported in the income tax returns. Deferred taxes are evaluated for realization on a jurisdictional basis. We record valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized. In making this assessment, management analyzes future taxable income, reversing temporary differences and ongoing tax planning strategies. Should a change in circumstances lead to a change in judgment about the realizability of deferred tax assets in future years, we will adjust related valuation allowances in the period that the change in circumstances occurs, along with a corresponding increase or charge to income. ​ We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of our position. The tax benefit recognized in the financial statements for a particular tax position is based on the largest benefit that is more likely than not to be realized. The amount of unrecognized tax benefits is adjusted as appropriate for changes in facts and circumstances, such as significant amendments to existing tax laws, new regulations or interpretations by the taxing authorities, new information obtained during a tax examination, or resolution of an examination. We recognize both accrued interest and penalties associated with uncertain tax positions as a component of provision for income taxes in the consolidated statements of operations. ​ The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws and regulations may change as a result of changes in fiscal policy, changes in legislation, the evolution of regulations and court rulings. Therefore, the actual liability for U.S. or foreign taxes may be materially different from our estimates, which could require us to record additional tax liabilities or to reduce previously recorded tax liabilities, as applicable. ​ Contingent Legal Expenses ​ Contingent legal fees are expensed in the consolidated statements of operations in the period that the related revenues are recognized. In instances where there are no recoveries from potential infringers, no contingent legal fees are paid; however, we may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement. ​ Research and Development Expenses ​ Research and development expenditures are expensed in the period incurred. ​ Foreign Currency Remeasurement ​ The functional currency of our foreign subsidiaries is the U.S. dollar. Local currency financial statements are remeasured into U.S. dollars at the exchange rate in effect as of the balance sheet date for monetary assets and liabilities and the historical exchange rate for nonmonetary assets and liabilities. Expenses are remeasured using the average exchange rate for the period, except items related to nonmonetary assets and liabilities, which are remeasured using historical exchange rates. All remeasurement gains and losses are included in determining net loss. Transaction gains and losses were not significant during 2022, 2021 or 2020. ​ Earnings (Loss) Per Share ​ Basic earnings (loss) per share is calculated by dividing net income (loss) by the weighted-average common shares outstanding during the period. Diluted earnings (loss) per share is calculated by dividing the net income (loss) by the weighted-average shares and dilutive potential common shares outstanding during the period. Dilutive potential shares consist of dilutive shares issuable upon the exercise of outstanding stock options and warrants computed using the treasury stock method, shares issuable under the conversion feature of a convertible note using the “if-converted” method, and shares issuable upon the vesting of RSAs and RSUs. In periods of net loss, basic and diluted loss per share are the same, as the effect of dilutive potential shares on loss per share is anti-dilutive. ​

The license fee revenue was recognized when we granted the license of our patents to SK hynix, since the performance obligation was satisfied at a point in time. In connection with the receipt of this fee, during the second quarter of 2021, we recorded a provision for income taxes of $6.6 million related to the Korean withholding tax incurred. ​ Net product sales by country presented below are based on the billing location of the customer (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2022 2021 ​ 2020 United States ​ $ 39,545 ​ $ 53,519 ​ $ 35,826 People's Republic of China(1) ​ ​ 114,480 ​ ​ 39,480 ​ ​ 6,071 Other countries ​ ​ 7,612 ​ ​ 9,356 ​ ​ 5,337 Total net sales ​ $ 161,637 ​ $ 102,355 ​ $ 47,234 (1) China includes Hong Kong and Taiwan. ​ The United States and China accounted for more than 10% of our net product sales for 2022, 2021 and 2020. ​ Earnings (Loss) Per Share ​ The following table shows the computation of basic and diluted earnings (loss) per share of common stock (in thousands, except per share data): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2022 ​ 2021 ​ 2020 Numerator: ​ ​ ​ ​ ​ ​ ​ ​ ​ Net (loss) income ​ $ (33,370) ​ $ 4,831 ​ $ (7,268) Denominator: ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted-average basic shares outstanding ​ ​ 231,487 ​ ​ 218,171 ​ ​ 183,594 Effect of dilutive securities ​ ​ — ​ ​ 7,418 ​ ​ — Weighted-average diluted shares ​ ​ 231,487 ​ ​ 225,589 ​ ​ 183,594 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic (loss) earnings per share ​ $ (0.14) ​ $ 0.02 ​ $ (0.04) Diluted (loss) earnings per share ​ $ (0.14) ​ $ 0.02 ​ $ (0.04) ​ We computed net loss per share using the two-class method required for unvested participating securities through the three months ended March 28, 2020 as restricted stock awards were considered participating securities until they vested in full during that quarter.

Credit Agreement
Credit Agreement	Note 3—Credit Agreement ​ On October 31, 2009, Netlist and Silicon Valley Bank (“SVB”) entered into a credit agreement, which may from time to time be amended, modified, supplemented or restated, (“the SVB Credit Agreement”), which provides for a revolving line of credit up to $10.0 million, as amended. The SVB Credit Agreement was most recently amended on April 29, 2022, and the borrowing base is limited to 85% of eligible accounts receivable, subject to certain adjustments, and 50% of eligible inventory. Borrowings accrue interest on advance at a per annum rate equal to the greater of 0.75% above the Wall Street Journal prime rate (“Prime Rate”) or 4.25%. The maturity date is April 28, 2023, as amended. ​ The SVB Credit Agreement requires letters of credit to be secured by cash, which is classified as restricted cash in the accompanying consolidated balance sheets. As of December 31, 2022 and January 1, 2022, (i) outstanding letters of credit were $18.6 million and $10.8 million, respectively, and (ii) outstanding borrowings were $4.9 million and $7.0 million, respectively. There was no availability under the revolving line of credit as of December 31, 2022 and January 1, 2022. ​ As of December 31, 2022, all obligations under the SVB Credit Agreement were secured by a first priority security interest in our tangible and intangible assets. The SVB Credit Agreement subjects us to certain affirmative and negative covenants, including financial covenants with respect to our liquidity and restrictions on the payment of dividends. As of December 31, 2022, we were in compliance with our covenants under the SVB Credit Agreement.

Debt
Debt	Note 4—Debt ​ Our debt consisted of the following (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ 2022 2021 Notes payable ​ $ 447 ​ $ 562 Less: amounts due within one year ​ ​ (447) ​ ​ (562) Long-term debt ​ $ — ​ $ — ​ Secured Convertible Note ​ On November 18, 2015, in connection with entering into the Joint Development and License Agreement (the “JDLA”) with Samsung, we issued to SVIC a secured convertible note (the “SVIC Note”) and stock purchase warrant (the “SVIC Warrant”). The SVIC Note had an original principal amount of $15.0 million, accrued interest at a rate of 2.0% per year, was due and payable in full on December 31, 2021, and was convertible into shares of our common stock at a conversion price of $1.25 per share, subject to certain adjustments, on the maturity date of the SVIC Note. Upon our change of control prior to the maturity date of the SVIC Note, the SVIC Note might, at our option, be assumed by the surviving entity or be redeemed upon the consummation of such change of control for the principal and accrued but unpaid interest as of the redemption date. The SVIC Warrant granted SVIC a right to purchase 2,000,000 shares of our common stock at an exercise price of $0.30 per share, subject to certain adjustments, was only exercisable in the event we would exercise our right to redeem the SVIC Note prior to its maturity date, and would expire on December 31, 2025. In December 2021, we repaid the full amounts outstanding under the SVIC Note and issued 2,000,000 shares of our common stock upon the exercise of 2,000,000 of our warrants by SVIC for cash proceeds of $0.6 million. ​ The SVIC Warrant was valued at $1.2 million, based on its relative fair value, and was recorded as a debt discount. We also recorded $0.2 million of debt issuance costs as a debt discount for professional services fees rendered in connection with the transaction. These amounts were being amortized to interest expense over the term of the SVIC Note using the interest method. For 2021 and 2020, we amortized $0.2 million and $0.2 million, respectively, to interest expense in the accompanying consolidated statements of operations. The effective interest rate, including accretion of the SVIC Note to par and amortization of debt issuance costs, was approximately 3.4%. ​ In connection with the SVIC Note, SVIC was granted a first priority security interest in our patent portfolio and a second priority security interest in all of our other tangible and intangible assets. Upon issuance of the SVIC Note, Netlist, SVB and SVIC entered into an Intercreditor Agreement pursuant to which SVB and SVIC agreed to their relative security interests in our assets. Additionally, upon issuance of the SVIC Note and the SVIC Warrant, Netlist and SVIC entered into a Registration Rights Agreement pursuant to which we were obligated to register with the Securities and Exchange Commission, upon demand by SVIC, the shares of our common stock issuable upon conversion of the SVIC Note or upon exercise of the SVIC Warrant. The SVIC Note subjected us to certain affirmative and negative operating covenants. We made the repayment of $16.8 million on December 27, 2021 and SVIC purchased 2,000,000 shares of common stock at an exercise price of $0.30 per share on December 28, 2021. As a result, neither the SVIC Note nor the SVIC Warrant remained outstanding as of December 31, 2022 and January 1, 2022. ​ Paycheck Protection Program Loan ​ On April 23, 2020, we entered into an unsecured promissory note with a principal amount of $0.6 million through Hanmi Bank under the Paycheck Protection Program (“PPP”) (the “PPP Loan”) administered by the Small Business Administration (“SBA”) and established as part of the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”). The PPP Loan bore interest at 1.0% per annum and would mature on April 23, 2022 with the first six months of interest and principal payments deferred. The amount borrowed under the PPP Loan was guaranteed by the SBA and was eligible for forgiveness in an amount equal to the sum of the eligible costs, including payroll, benefits, rent and utilities, incurred by us during the 24-week period beginning on the date we received the proceeds. The PPP Loan contained customary events of default, and the occurrence of an event of default might result in a claim for the immediate repayment of all amounts outstanding under the PPP Loan. In May 2021, the full amount outstanding under the PPP Loan was forgiven, resulting in a gain of $0.6 million during the second quarter of 2021. ​ Insurance Policy Finance Agreement ​ As of December 31, 2022 and January 1, 2022, we had $0.4 million and $0.6 million, respectively, in short-term notes payable for the financing of insurance policies. On December 29, 2021, we entered into a short-term note payable for $0.6 million bearing interest at 3.9% to finance insurance policies. Principal and interest payments on this note began January 15, 2022 and were made evenly based on a straight line amortization over a 9-month period with the final payment being made on September 15, 2022. On January 4, 2023, we entered into a short-term notes payable for $0.4 million bearing interest at 7.2% to finance insurance policies. Principal and interest payments on this note began January 15, 2023 and are made evenly based on a straight line amortization over a 9-month period.

In making such judgments, significant weight is given to evidence that can be objectively verified. As of December 31, 2022 and January 1, 2022, a valuation allowance of $52.0 million and $43.1 million, respectively, has been provided based on our assessment that it is more likely than not that sufficient taxable income will not be generated to realize the tax benefits of the temporary differences. The valuation allowance increased by $8.9 million, $3.8 million and $1.7 million during 2022, 2021, and 2020, respectively. These increases in these years primarily relate to the increases in the net operating loss (“NOL”) carryforward and tax credit carryforwards. ​ As of December 31, 2022, we had $166.1 million of federal NOL carryforwards, of which $104.2 million will expire from 2029 through 2037, and $61.9 million of which will be carried forward indefinitely, and $84.0 million of state NOL carryforwards that will expire from 2029 through 2041. We had federal and state tax credit carryforwards of $2.5 million and $2.3 million, respectively, at December 31, 2022. Federal tax credit carryforwards began to expire in 2022 and state tax credits carryforward indefinitely. In addition, we had $0.5 million of NOL in the People’s Republic of China (“PRC”) that expired in 2022, with a remaining amount of $2.6 million of NOL carryforward in the PRC at December 31, 2022. Utilization of the NOL and tax credit carryforwards is subject to an annual limitation due to the ownership percentage change limitations provided by Section 382 of the Internal Revenue Code (the “Code”) and similar state and foreign law provisions. Under Section 382 of the Code, substantial changes in our ownership may limit the amount of NOL and tax credit carryforwards that are available to offset taxable income. The annual limitation would not automatically result in the loss of NOL and tax credit carryforwards but may limit the amount available in any given future period. Additional limitations on the use of these tax attributes could occur in the event of possible disputes arising in examination from various taxing authorities. ​ We file income tax returns with federal, state and foreign jurisdictions. We are no longer subject to Internal Revenue Service (“IRS”) or state examinations for periods prior to 2018, although certain carryforward attributes that were generated prior to 2018 may still be adjusted by the IRS. ​ We include interest and penalties related to uncertain tax positions within the provision for income taxes. As of December 31, 2022 and January 1, 2022, the interest or penalties accrued related to unrecognized tax benefits were insignificant, and during 2022, 2021 and 2020, the interest and penalties related to uncertain tax position recorded were insignificant. As of December 31, 2022, we had no unrecognized tax benefits that would significantly change in the next 12 months.

Commitments and Contingencies
Commitments and Contingencies	Note 7—Commitments and Contingencies ​ Contingent Legal Expenses ​ We may retain the services of law firms that specialize in patent licensing and enforcement and patent law in connection with our licensing and enforcement activities. These law firms may be retained on a contingent fee basis whereby such law firms are paid on a scaled percentage of any negotiated fee, settlements or judgments awarded based on how and when the fees, settlements or judgments are obtained. ​ Litigation and Patent Reexaminations ​ We own numerous patents and continue to seek to grow and strengthen our patent portfolio, which covers various aspects of our innovations and includes various claim scopes. We plan to pursue avenues to monetize our intellectual property portfolio, in which we would generate revenue by selling or licensing our technology, and we intend to vigorously enforce our patent rights against alleged infringers of such rights. We dedicate substantial resources to protecting and enforcing our intellectual property rights, including with patent infringement proceedings we file against third parties and defense of our patents against challenges made by way of reexamination and review proceedings at the U.S. Patent and Trademark Office (“USPTO”) Patent Trial and Appeal Board (“PTAB”). We expect these activities to continue for the foreseeable future, with no guarantee that any ongoing or future patent protection or litigation activities will be successful, or that we will be able to monetize our intellectual property portfolio. ​ Any litigation, regardless of its outcome, is inherently uncertain, involves a significant dedication of resources, including time and capital, and diverts management’s attention from our other activities. As a result, any current or future claims, allegations, or challenges by or against third parties, whether eventually decided in our favor or settled, could materially adversely affect our business, financial condition and results of operations. Additionally, the outcome of pending or future litigation and/or related patent reviews and reexaminations, as well as any delay in their resolution, could affect our ability to continue to sell our products, protect against competition in the current and expected markets for our products or license or otherwise monetize our intellectual property rights in the future. ​ Google Litigations ​ On December 4, 2009, Netlist filed a patent infringement lawsuit against Google, Inc. (“Google”) in the U.S. District Court for the Northern District of California (the “NDCA”), seeking damages and injunctive relief based on Google’s alleged infringement of our U.S. Patent No. 7,619,912 (the “‘912 Patent”) which relates generally to technologies to implement rank multiplication. The NDCA case was stayed, pending challenges to the ‘912 Patent before the USPTO. Eventually, the U.S. Court of Appeals for the Federal Circuit confirmed the ‘912 Patent’s validity on June 15, 2020, and the NDCA case stay was lifted and the case proceeded before Hon. Senior Judge Armstrong, where the parties entered cross motions for summary judgment. On May 5, 2022, Hon. Chief Judge Seeborg entered an Order granting Netlist’s Motion for Summary Judgement that Claim 16 of the ‘912 Patent is not subject to Google’s pleaded defense of Intervening Rights. On July 13, 2022, Chief Judge Seeborg ordered – shortly before the planned July 14, 2022 case management conference – that the case be stayed for a 90-day period pending the outcome of an action initiated by Samsung Electronic Co., Ltd. (“Samsung”) in Delaware involving the ‘912 Patent. Samsung’s Delaware cause of action for the ‘912 Patent was dismissed by Judge Andrews there, and Netlist shortly thereafter brought a lawsuit against Samsung for their infringement of at least the ‘912 Patent in the U.S. District Court for the Eastern District of Texas (“EDTX”). In light of the pendency of the ‘912 Patent matter Netlist brought against Samsung in EDTX, Chief Judge Seeborg entered an order via stipulation on October 17, 2022 staying the NDCA Google case until the resolution of that EDTX action. ​ On July 26, 2022, Netlist filed a patent infringement lawsuit against Google Cloud EMEA Limited, Google Germany GmbH, Redtec Computing GmbH, and Google, Inc., seeking damages based on those defendants’ infringement of European Patents EP 2,454,735 (“EP735”) and EP 3,404,660 (“EP660”), which both generally relate to load reduced dual in line memory modules (“LRDIMM”) technologies. As of the reporting date, Google’s submitted its statement of defense. The date for a final oral hearing on the issues in that German action are currently scheduled for November 9, 2023. ​ Micron Litigations ​ On April 28, 2021, Netlist filed a complaint for patent infringement against Micron Technology, Inc. (“Micron”) in the U.S. District Court for the Western District of Texas, Waco Division (“WDTX”) (Case No. 6:21-cv00431 & Case No. 6:21-cv-00430). These proceedings are based on the alleged infringement by Micron’s LRDIMM and Micron’s non-volatile dual in line memory modules (“NVDIMM”) enterprise memory modules under four U.S. patents – U.S. Patent Nos. 10,489,314 (the “’314 Patent”), 9,824,035 (the “’035 Patent”), 10,268,608 (the “’608 Patent”), and 8,301,833 (the “’833 Patent”). The case has been assigned to Hon. Judge Lee Yeakel, and the parties completed briefing on their claim construction arguments. On May 11, 2022, Judge Yeakel entered a stay of the case pending the resolution of Micron’s requested Inter Partes Review (“IPR”) proceedings against the four patents asserted by Netlist in this case (the ‘833, ‘035, ‘608, and ‘314 Patents). Following entry of that stay order on September 2, 2022, Micron moved the Court to “temporarily” lift the stay to add counterclaims for declaratory judgment of noninfringement of U.S. Patent Nos. 9,858,215 (the “’215 Patent”), 10,860,506 (the “’506 Patent”), 10,949,339 (the “’339 Patent”), 11,016,918 (the “’918 Patent”), 11,232,054 (the “’054 Patent”), 11,093,417 (the “’417 Patent”), and the ‘912 Patent. This addition would encompass four of the six patents asserted in Netlist’s initial EDTX filing against Micron (Case No. 2:22-cv-00203 – further details of this case below), and all three of the patents asserted in Netlist’s second EDTX filing against Micron (Case No. 2:22-cv-00294 – further details of this case below). On October 5, 2022, Judge Yeakel denied Micron’s motion and returned the action to a stayed state, asking only that the parties submit status reports within 10 days of any activity in the relevant underlying IPR proceedings. As of the reporting date, the matter remains stayed pending the outcome of the related IPR proceedings. ​ As noted above, Micron filed requests to bring IPR proceedings against Netlist’s ‘314, ‘035, ‘068, and ‘833 Patents. As of the reporting date, the PTAB granted Micron’s request for the ‘035, ‘833, and ‘314 Patents, but denied its request for the ‘608 Patent. The PTAB further denied Micron’s request for rehearing on the ‘608 Patent’s institution denial. As of the reporting date, the IPR trials under the ‘035, ‘833, and ‘314 Patents are proceeding following Netlist’s timely submissions of its related Patent Owner Responses. Oral arguments for the ‘035, ‘833, and ‘314 Patents are set for April, June, and August 2023, respectively. ​ On March 31, 2022, Netlist filed a patent infringement lawsuit against Micron in Germany (“Micron Dusseldorf Case”), seeking damages based on their infringement of EP735 and EP660. On June 24, 2022, Netlist filed an extension of its Complaint requesting injunctive relief. Micron filed its statement of defense, thus setting Netlist’s deadline for a response as December 1, 2022. Further, Micron initiated a nullity proceeding against the asserted EP patents in this action, making Netlist’s response to the same as November 19, 2022. As of the reporting date, the date for the oral hearing in the Micron Dusseldorf Case is set for May 3, 2023. ​ ​ 2022, Micron moved to withdraw its motion to stay in this action, which Chief Judge Gilstrap entered on October 13, 2022. On October 21, 2022, Chief Judge Gilstrap ordered that this Micron action and a parallel action by Netlist against Samsung on the same patents (22-cv-00293-JRG) be consolidated and set for a joint scheduling conference on November 17, 2022, further instructing that the Samsung action be considered the “LEAD CASE” and that any further filings from either action be submitted in that case for all pretrial matters. As of the reporting date, the consolidated case stands ready to proceed with a claim construction hearing set for October 5, 2023, and trial beginning on April 15, 2024. ​ Samsung Litigations ​ On May 28, 2020, Netlist filed a complaint against Samsung in the U.S. District Court for the Central District of California for Samsung’s breach of the parties’ Joint Development and License Agreement (“JDLA”). On July 22, 2020, Netlist amended its complaint to seek a Declaratory Judgment that it properly terminated the JDLA in light of Samsung’s material breaches. On October 14, 2021, the Court entered summary judgment in Netlist’s favor and confirmed Netlist properly terminated the JDLA as of July 15, 2020. On February 15, 2022, the Court entered a Final Judgment in favor of Netlist on each of its three claims and confirmed conclusively that all licenses granted under the JDLA were terminated. On February 25, 2022, Samsung filed a Notice of Appeal, and the Federal Court of Appeals for the Ninth Circuit issued a Time Schedule Order on February 28, 2022. On August 4, 2022, Netlist filed a cross-appeal seeking the Appeal Court’s reconsideration of the District Court’s finding that the fees Netlist paid to PwC were consequential damages, rather than recoverable general damages. As of the reporting date, the parties have completed briefing on the appeal and cross-appeal, and await the Appeal Court setting a date for oral argument in 2023. ​ On October 15, 2021, Samsung filed a declaratory judgement action against Netlist in the U.S. District Court for the District of Delaware (“DDE”), requesting in relevant part that the Delaware District Court declare that Samsung does not infringe Netlist’s U.S. Patent Nos. 9,858,218 (the “’218 Patent”), 10,217,523 (the “’523 Patent”), 10,474,595 (the “’595 Patent”), and the ‘506, ‘339, ‘912 and ‘918 Patents. As of the reporting date, Samsung seeks leave to add the ‘054 Patent (issued Jan. 25, 2022) to the action. Netlist believes Samsung’s claims levied in the DDE action meritless, and the relief Samsung requests unjustified. Netlist filed a motion seeking dismissal of Samsung’s operative DDE complaint, and an opposition contesting the inclusion of the ‘054 Patent as part of Samsung’s proposed second amended complaint filing. On August 1, 2022, the Court entered an Order on the pending motions denying Samsung’s request to amend its operative complaint a second time to add a count against the ‘054 Patent, and granting-in-part Netlist’s motion that various causes of action be dismissed. Specifically, Hon. Judge Andrews dismissed all of Samsung’s counts related to Netlist’s ‘912, ‘506, ‘339, and ‘918 Patents. Thus, on August 22, 2022, Netlist entered its Answer to Samsung’s remaining Counterclaims. On September 12, 2022, Netlist amended its Counterclaims to include counterclaims tying Google, LLC and Alphabet, Inc. to the action. On November 15, 2022, Google, LLC and Alphabet, Inc. responded to Netlist’s Counterclaims by filing a Motion to Dismiss or alternatively to Sever and Stay the claims directed at Google specifically from the action. As of the reporting date, briefing has concluded and Netlist requested an oral argument on Google’s motion. Further, the Court set the Claim Construction hearing for October 20, 2023, and the beginning of the Jury Trial on February 3, 2025. ​ On November 19, 2021, Samsung filed IPR requests contesting the validity of U.S. Patent Nos. 9,858,218 (the “’218 Patent”), 10,474,595 (the “’595 Patent”), and 10,217,523 (the “’523 Patent”). Netlist filed its initial responses to Samsung’s petitions on February 18, 2022, contesting the institution of any IPR on the grounds propounded. As of the reporting date, the PTAB has granted Samsung’s IPR requests related to the ‘218, ‘523, and ‘595 Patents. Netlist filed its Patent Owner’s Response for the ‘523 Patent IPR on August 4, 2022, and its Patent Owner Responses for the ‘218 Patent and ’595 Patent IPRs on August 15, 2022. As of the reporting date, Oral Arguments were heard for the ‘523 IPR (February 1, 2023), and the ‘218 Patent and ‘595 Patent IPRs (February 15, 2023), leaving the PTAB to enter its final written decision on all three IPRs by the second quarter of 2023. ​ On December 20, 2021, Netlist filed a complaint for patent infringement against Samsung, Samsung Semiconductor, Inc., and Samsung Electronics America, Inc. in the EDTX (Case No. 2:21-cv-463) under the ‘506, ‘339, and ‘918 Patents. Samsung responded to Netlist’s complaint on April 12, 2022, and Chief Judge Gilstrap ordered a scheduling conference be set. On May 3, 2022, Netlist entered a First Amended Complaint pursuant to the Federal Rules of Civil Procedure (“FRCP”) Rule 15, adding claims for infringement under three additional patents: the ‘060, ‘160, and ‘054 Patents. On May 4, 2022, Netlist complied with the EDTX local patent rules and served its preliminary infringement contentions on Samsung. On May 27, 2022, Samsung moved to stay this action and sever the patents it sought to add to its Declaratory Judgement action in Delaware. On August 2, 2022, Samsung withdrew that first motion to stay in light of Judge Andrews’s order mandating dismissal of all Samsung’s claims related to the Texas Netlist patents the day before. On August 30, 2022 Samsung moved to stay the action a second time, this time in light of its IPR petitions, and its appeal of the Central District California Judgment at the 9th Circuit Court of Appeals. The matter was fully briefed as of October 17, 2022. As of the reporting date, the claim construction hearing took place on November 4, 2022 in Hon. Magistrate Judge Roy Payne’s Court. On December 14, 2022, Magistrate Payne entered an order construing all fourteen claim terms in dispute. As of the reporting date, the matter is set for pretrial proceedings. The Final Pretrial Conference is currently set for March 27, 2023, while the trial start is now set for April 17, 2023. ​ On February 17, 2022, Samsung filed an IPR request contesting the validity of only claim 16 within the ‘912 Patent. Samsung then filed two additional IPR requests contesting the validity of the ‘506 and ‘339 Patents. Netlist filed its Patent Owner’s Preliminary Response for the ‘912 and ‘339 Patent IPRs on July 21, 2022, and for the ‘506 Patent IPR on July 28, 2022. On January 19, 2023, the PTAB instituted IPR trials on both the ‘912 and ‘339 Patents. The following day, the PTAB instituted an IPR trial on the ‘506 Patent. On October 19, 2022, the PTAB instituted IPR trials on the ‘912 Patent and ‘339 Patent, while two days later it instituted an IPR trial on the ’506 Patent. On November 2, 2022, Netlist file a Request for Rehearing for the ‘912 Patent institution decision, while simultaneously requesting review of the institution decision be undertaken by the USPTO’s Precedential Opinion Panel. On January 5, 2023, USPTO Director Katherine K. Vidal entered an Order in the proceeding mandating a sua sponte ​ On May 17, 2022, Samsung filed two IPR petitions contesting the validity of Netlist’s ‘918 and ‘054 Patents. On December 6, 2022, the Board instituted an IPR trial for the ‘054 Patent, and then instituted an IPR trial for the ‘918 Patent the next day. On December 9, 2022, the Board set a joint schedule for both IPRs, making Netlist’s deadline to file its Patent Owner Response March 1, 2023. ​ On June 3, 2022, Netlist filed a patent infringement lawsuit against Samsung in Dusseldorf, Germany, seeking damages for Samsung’s infringement of Netlist’s Patents EP735 and EP660. The Dusseldorf Court set an Oral Hearing date for September 5, 2023. ​ On August 1, 2022, Netlist filed a complaint for patent infringement against Samsung, Samsung Semiconductor, Inc., and Samsung Electronics America, Inc. in the EDTX (Case No. 2:22-cv-00293) under the ‘912 Patent, which relates generally to technologies to implement rank multiplication. On August 15, 2022, Netlist filed its first amended complaint here, further addressing Samsung’s infringement of the ‘215 Patent and ‘417 Patent. On August 31, 2022, Samsung Semiconductor, Inc. and Samsung Electronics America, Inc. sought and received extensions of time to respond to Netlist’s first amended complaint until October 7, 2022. Before answering on September 20, 2022, Samsung collectively moved the Court to sever and transfer the ‘912 Patent from the action and stay the remaining portions of this proceeding in light of Samsung’s appeal before 9th Circuit Court of Appeals. The matter is fully briefed, but Samsung’s response deadline remains currently set for November 29, 2022. Apart from Samsung’s early motion practice and its remaining response deadline, on October 21, 2022, Chief Judge Gilstrap ordered that this action and a parallel action by Netlist against Micron on the same patents (22-cv-00294-JRG) be consolidated and set for a joint scheduling conference on November 17, 2022, further instructing that this Samsung action be considered the “LEAD CASE” and that any further filings from either action be submitted in therefore all pretrial matters. On January 20, 2023, following the entry of Samsung’s First Amended Answer, Netlist moved the Court for Leave to File a Second Amended Complaint that would include additional claims of infringement related specifically to Samsung’s infringement of Netlist’s ‘608 Patent.

We may make matching contributions on the contributions of a participant on a discretionary basis. During 2022 and 2021, our matching contributions totaled $0.1 million and $0.1 million, respectively. During 2020, we did not make any matching contributions.

Major Customers, Suppliers and Products	Note 10—Major Customers, Suppliers and Products ​ Our net product sales have historically been concentrated in a small number of customers. The following table sets forth the percentage of net product sales made to customers that each comprise 10% or more of total net product sales: ​ ​ ​ ​ ​ ​ ​ ​ ​ 2022 ​ 2021 ​ 2020 Customer A ​ 39% ​ 16% ​ * Customer B ​ * ​ * ​ 17% Customer C ​ 14% ​ * ​ * * Less than 10% of total net product sales ​ As of December 31, 2022, one customer represented approximately 69% of aggregate gross accounts receivable. As of January 1, 2022, four customers represented approximately 26%, 16%, 13% and 13%, respectively, of aggregate gross accounts receivable. The loss of any of our significant customers or a reduction in sales to or difficulties collecting payments from any of these customers could significantly reduce our net product sales and adversely affect our operating results. We mitigate risks associated with foreign receivables by purchasing comprehensive foreign credit insurance. We resell certain component products to end-customers that are not reached in the distribution models of the component manufacturers, including storage customers, appliance customers, system builders and cloud and datacenter customers. For 2022, 2021 and 2020, resales of these products represented approximately 84%, 79% and 66%, respectively, of our net product sales. ​ Our purchases are typically concentrated in a small number of suppliers. The following table shows the percentage of purchases made from suppliers that each comprise 10% or more of total purchases: ​ ​ ​ ​ ​ ​ ​ ​ ​ 2022 ​ 2021 ​ 2020 Supplier A ​ * ​ 40% ​ 28% Supplier B ​ 73% ​ 30% ​ * Supplier C ​ 11% ​ 10% ​ 14% Supplier D ​ * ​ * ​ 11% * Less than 10% of purchases during the year ​ While we believe alternative suppliers may be available, our dependence on a small number of suppliers and the lack of any guaranteed sources for the essential components of our products and the components we resell exposes us to several risks, including the inability to obtain an adequate supply of these components, increases in their costs, delivery delays and poor quality. If we cannot obtain these components in the amounts needed on a timely basis and at commercially reasonable prices, we may not be able to develop or introduce new products, we may experience significant increases in our cost of sales if we are forced to procure components from alternative suppliers and are not able to negotiate favorable terms with these suppliers, we may experience interruptions or failures in the delivery of our products, or we may be forced to cease sales of products dependent on the components or resales of the components we resell to customers directly. Any of these events could have a material adverse effect on our business, operating results and financial condition.

Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation ​ Netlist, Inc. and its wholly owned subsidiaries (collectively the “Company”, “Netlist,” “we,” “us,” or “our”) provides high-performance memory solutions to enterprise customers in diverse industries. Our products in various capacities and form factors and the line of custom and specialty memory products bring industry-leading performance to server and storage appliance customers and cloud service providers. We license our portfolio of intellectual property including patents, in server memory, hybrid memory and storage class memory, to companies that implement our technology. We operate in one reportable segment, which is the design and manufacture of high-performance memory subsystems for the server, high-performance computing and communications markets. ​ The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts of Netlist, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, net sales and expenses. Actual results may differ materially from those estimates. We have evaluated events occurring subsequent to December 31, 2022, through the filing date of this Annual Report on Form 10-K and concluded that there were no events that required recognition and disclosures, other than those discussed elsewhere in the notes hereto. Certain prior period amounts have been reclassified to conform to the current period’s presentation. ​ Our fiscal year is the 52- or 53-week period that ends on the Saturday nearest to December 31. Our fiscal year 2022 ended on December 31, 2022, fiscal year 2021 ended on January 1, 2022, and fiscal year 2020 ended on January 2, 2021. All fiscal years presented in this Form 10-K, except fiscal year 2020, included 52 weeks. Additionally, all quarters, except the fourth quarter of 2020, included 13 weeks. Fiscal year 2020 included 53 weeks, with a 14 -week fourth quarter. Unless otherwise stated, references to particular years, quarters, months and periods refer to our fiscal years ended in January or December and the associated quarters, months and periods of those fiscal years. ​
Recently Adopted Accounting Standards	​ In the first quarter of 2022, we adopted the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity . This ASU amends the guidance on convertible instruments and the derivatives scope exception for contracts in an entity's own equity, and also improves and amends the related earnings per share guidance for both Subtopics. The adoption of this ASU did not have an impact on the Company’s condensed consolidated financial statements as the Company paid off its convertible debt in December 2021.
Revenue Recognition	Revenue Recognition ​ Product Revenue ​ Revenue is recognized when control is transferred to customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods and services. Revenue recognition is evaluated through the five steps outlined within the accounting guidance. Substantially all of our product sales relate to products sold at a point in time through ship-and-bill performance obligations. At contract inception, an assessment of the goods and services promised in the contracts with customers is performed and a performance obligation is identified for each distinct promise to transfer to the customer a good or service (or bundle of goods or services). To identify the performance obligations, we consider all of the goods or services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. Contracts with customers are comprised of customer purchase orders, invoices (including our standard terms and conditions) and written contracts. ​ License Revenue ​ For licenses of technology, recognition of revenue is dependent upon whether we have delivered rights to the technology, and whether there are future performance obligations under the contract. In some instances, the license agreements call for future events or activities to occur in order for milestone amounts to become due from the customer. The terms of such agreements include payments to us of one or more of the following: non-refundable upfront fees and royalties on net sales of licensed products. Historically, these license agreements have not included other future performance obligations for us once the license has been transferred to the customer. ​ Revenue from non-refundable upfront payments is recognized when the license is transferred to the customer and we have no other performance obligations. ​ Performance Obligations ​ Net product sales and related cost of sales are primarily the result of promises to transfer products to customers. For performance obligations related to substantially all of the ship-and-bill products, control transfers at a point in time when title transfers upon shipment of the product to the customer, and for some sales, control transfers when title is transferred at time of receipt by the customer. Once a product has shipped or has been delivered, the customer is able to direct the use of, and obtain substantially all of the remaining benefits from, the asset. We consider control to have transferred upon shipment or delivery, because we have a present right to payment at that time, the customer has legal title to the asset, we have transferred physical possession of the asset, and the customer has the significant risks and rewards of ownership of the asset. ​ Amounts billed to our customers for shipping and handling are recorded in net sales. Shipping and handling costs incurred by us are included in cost of sales in the accompanying consolidated statements of operations. ​ Significant Payment Terms ​ For ship-and-bill type contracts with customers, the invoice states the final terms of the sale, including the description, quantity, and price of each product purchased. Payment terms are typically due within 30 days after delivery but, in limited instances, can range up to 90 days after delivery. Accordingly, our contracts with customers do not include a significant financing component. ​ Variable Consideration ​ Our revenue generating activities include variable consideration which is recorded as a reduction of the transaction price based upon expected amounts at the time revenue for the corresponding product sale is recognized. Common forms of variable consideration include limited rights of return for up to 30 days, except for sales of excess component inventories, which contain no right-of-return privileges and volume rebates for meeting established sales targets. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the anticipated performance and all information (historical, current and forecasted) that is reasonably available. ​ Returns for products sold are estimated using the expected value method and are recorded as a reduction in reported revenues at the time of sale based upon historical product return experience and is adjusted for known trends to arrive at the amount of consideration to which we expect to receive. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. ​ ​ ​ Contract Assets and Liabilities ​ We continually evaluate whether the revenue generating activities and advanced payment arrangements with customers result in the recognition of contract assets or liabilities. Generally, we do not have material amounts of contract assets since revenue is recognized as control of goods is transferred or as services are performed. As of January 1, 2022 and December 31, 2022, there were no contract liabilities. ​ Warranties ​ We offer standard product warranties generally ranging from one ​
Cash and Cash Equivalents	Cash and Cash Equivalents ​ Cash and cash equivalents consist of cash and short-term investments with original maturities of three months or less. ​
Restricted Cash	Restricted Cash ​ Our restricted cash consists of cash to secure standby letters of credit (see Note 3). ​
Fair Value Measurements	Fair Value Measurements ​ Certain assets and liabilities are accounted for at fair value. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in one of those three levels based on the lowest level input that is significant to the fair value measurement in its entirety. ​ ● Level 1 – inputs are based on unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access. An active market is defined as a market in which transactions for the assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis. ● Level 2 – inputs are based on quoted prices of similar instruments in active markets, quoted prices for identical or similar instruments in market that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. ● Level 3 – inputs are generally unobservable inputs for the asset or liability, which are typically based on management’s estimates of assumptions that market participants would use in pricing the assets and liabilities. The fair values are therefore determined using model-based techniques, including option pricing models and discounted cash flow models. ​ Our financial instruments consist principally of cash and cash equivalents, restricted cash, a revolving line of credit and note payable. Cash equivalents consist of short-term investments with original maturities of three months or less and restricted cash consists of cash to secure standby letters of credit (see Note 3). The carrying value of these instruments approximates their fair value due to their short-term nature. The fair value of the revolving line of credit and the note payable is estimated by using current applicable rates for similar instruments as of the balance sheet date and an assessment of the credit rating. The carrying values of the revolving line of credit as of December 31, 2022 and January 1, 2022 and the note payable as of December 31, 2022 and January 1, 2022 approximate fair value because the interest rate yield is near current market rates for comparable debt instruments. ​
Accounts Receivable, net	Accounts Receivable, net ​ We extend credit to our customers. An allowance for doubtful accounts is maintained for estimated losses resulting from the inability of our customers to make required payments. We specifically analyze the age of customer balances, historical bad debt experiences, customer creditworthiness and changes in customer payment terms when making estimates of the collectability of our accounts receivable balances. If we determine that the financial condition of any of our customers has deteriorated, whether due to customer specific or general economic issues, an increase in the allowance may be made. After all attempts to collect a receivable have failed, the receivable is written off. ​
Concentration of Credit Risk	Concentration of Credit Risk ​ Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents, and accounts receivable. We invest our cash equivalents primarily in money market mutual funds. Cash equivalents are maintained with high quality institutions, the composition and maturities of which are regularly monitored by management. At times, deposits held with financial institutions may exceed the amount of insurance provided by the Federal Deposit Insurance Corporation and the Securities Investor Protection Corporation. ​ ​
Inventories	Inventories ​ Inventories are valued at the lower of cost or the net realizable value. Cost is determined on an average cost basis which approximates actual cost on a first-in, first-out basis and includes raw materials, labor and manufacturing overhead. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. We evaluate inventory balances for excess quantities and obsolescence on a regular basis by analyzing estimated demand, inventory on hand, sales levels and other information and reduce inventory balances to net realizable value for excess and obsolete inventory based on this analysis. At the point of the write-down recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. ​
Property and Equipment	Property and Equipment ​ Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives, which generally range from three ​
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets ​ We evaluate the recoverability of the carrying value of long-lived assets held and used by us in our operations for impairment on at least an annual basis or whenever events or changes in circumstances indicate that their carrying value may not be recoverable. When such factors and circumstances exist, we compare the projected undiscounted future net cash flows associated with the related asset or group of assets over their estimated useful lives against their respective carrying amount. These projected future cash flows may vary significantly over time as a result of increased competition, changes in technology, fluctuations in demand, consolidation of our customers and reductions in average sales prices. If the carrying value is determined not to be recoverable from future operating cash flows, the asset is deemed impaired and an impairment loss is recognized to the extent the carrying value exceeds the estimated fair value of the asset. The fair value of the asset or asset group is based on market value when available, or when unavailable, on discounted expected cash flows. Management believes there is no impairment of long-lived assets as of December 31, 2022 and January 1, 2022. ​
Leases	Leases ​ We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, accrued expenses and other current liabilities, and operating lease liabilities on our consolidated balance sheets. Finance leases are included in property and equipment, accrued expenses and other current liabilities, and other liabilities in our consolidated balance sheets. ​ 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 at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. ​ We have lease agreements with lease and non-lease components, which are accounted for as a single lease component. We do not present short-term leases on the balance sheet, as those leases have a lease term of twelve months or less at inception and do not contain purchase options or renewal terms that we are reasonably certain to exercise. ​
Stock-Based Compensation	Stock-Based Compensation ​ Stock-based awards are comprised principally of stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”). Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as an expense over the requisite service period, which is the vesting period, on a straight-line basis, net of estimated forfeitures. We use the Black-Scholes option pricing model to determine the grant date fair value of stock options. The model requires us to estimate the expected volatility and expected term of the stock options, which are highly complex and subjective variables. The expected volatility is based on the historical volatility of our common stock. The expected term is computed using the simplified method as our best estimate given our lack of actual exercise history. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the expected term of the grant effective as of the date of the grant. The expected dividend assumption is based on our history and management’s expectation regarding dividend payouts. The grant-date fair value of RSAs and RSUs equals the closing price of our common stock on the grant date. ​
Income Taxes	Income Taxes ​ Deferred income tax assets and liabilities are recognized for temporary differences between the financial statement carrying amounts of assets and liabilities and the amounts that are reported in the income tax returns. Deferred taxes are evaluated for realization on a jurisdictional basis. We record valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized. In making this assessment, management analyzes future taxable income, reversing temporary differences and ongoing tax planning strategies. Should a change in circumstances lead to a change in judgment about the realizability of deferred tax assets in future years, we will adjust related valuation allowances in the period that the change in circumstances occurs, along with a corresponding increase or charge to income. ​ We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of our position. The tax benefit recognized in the financial statements for a particular tax position is based on the largest benefit that is more likely than not to be realized. The amount of unrecognized tax benefits is adjusted as appropriate for changes in facts and circumstances, such as significant amendments to existing tax laws, new regulations or interpretations by the taxing authorities, new information obtained during a tax examination, or resolution of an examination. We recognize both accrued interest and penalties associated with uncertain tax positions as a component of provision for income taxes in the consolidated statements of operations. ​ The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws and regulations may change as a result of changes in fiscal policy, changes in legislation, the evolution of regulations and court rulings. Therefore, the actual liability for U.S. or foreign taxes may be materially different from our estimates, which could require us to record additional tax liabilities or to reduce previously recorded tax liabilities, as applicable. ​
Contingent Legal Expenses	Contingent Legal Expenses ​ Contingent legal fees are expensed in the consolidated statements of operations in the period that the related revenues are recognized. In instances where there are no recoveries from potential infringers, no contingent legal fees are paid; however, we may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement. ​
Research and Development Expenses	Research and Development Expenses ​ Research and development expenditures are expensed in the period incurred.
Foreign Currency Remeasurement	Foreign Currency Remeasurement ​ The functional currency of our foreign subsidiaries is the U.S. dollar. Local currency financial statements are remeasured into U.S. dollars at the exchange rate in effect as of the balance sheet date for monetary assets and liabilities and the historical exchange rate for nonmonetary assets and liabilities. Expenses are remeasured using the average exchange rate for the period, except items related to nonmonetary assets and liabilities, which are remeasured using historical exchange rates. All remeasurement gains and losses are included in determining net loss. Transaction gains and losses were not significant during 2022, 2021 or 2020. ​
Earnings (Loss) Per Share	Earnings (Loss) Per Share ​ Basic earnings (loss) per share is calculated by dividing net income (loss) by the weighted-average common shares outstanding during the period. Diluted earnings (loss) per share is calculated by dividing the net income (loss) by the weighted-average shares and dilutive potential common shares outstanding during the period. Dilutive potential shares consist of dilutive shares issuable upon the exercise of outstanding stock options and warrants computed using the treasury stock method, shares issuable under the conversion feature of a convertible note using the “if-converted” method, and shares issuable upon the vesting of RSAs and RSUs. In periods of net loss, basic and diluted loss per share are the same, as the effect of dilutive potential shares on loss per share is anti-dilutive.
