Substantial Doubt about Going Concern [Text Block]

The Company has incurred net losses of $29.4 million, $34.5 million and $25.4 million for the fiscal years ended 2019, 2018 and 2017, respectively, and net cash outflows from operations of $21.0 million, $28.1 million and $25.9 million for the fiscal years ended 2019, 2018 and 2017, respectively. In addition, the Company has continued to experience a significant decline in its cash and cash equivalents and marketable debt securities, which was primarily a result of funding operating losses, of which a significant component relates to the Company’s ongoing investments in the research and development of Wearable products. These negative financial conditions raise substantial doubt regarding the Company’s ability to continue as a going concern.

Principles of Consolidation

The consolidated financial statements include the accounts of the Kopin Corporation, its wholly owned subsidiaries and a majority owned 80% subsidiary, eMDT America Inc. ("eMDT"), located in California (collectively the Company). Net loss attributable to noncontrolling interest in the Company's Consolidated Statement of Operations represents the portion of the results of operations of which is allocated to the shareholders of the equity interests not owned by the Company. All intercompany transactions and balances have been eliminated.

Revenue Recognition

Revenue Recognition - 2019 and 2018

The Company adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) effective December 31, 2017 and applied the modified retrospective method. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of accumulated deficit. 2017 results have not been revised and continue to be reported under the accounting standards in effect for those periods. The Company expects the impact of the adoption of the new standard to be material to the Company's results of operations on an ongoing basis. Significant changes to the Company's accounting policies as a result of adopting Topic 606 are discussed below.

Substantially all of our product revenues are either derived from the sales of components for use in military applications or our wearable technology components that can be integrated to create industrial and consumer headset systems. We also have development contracts for the design, manufacture and modification of products for the U.S. government or a prime contractor for the U.S. government or for a customer that sells into the industrial or consumer markets. The Company's contracts with the U.S. government are typically subject to the Federal Acquisition Regulations (“FAR”) and are priced based on estimated or actual costs of producing goods. The FAR provides guidance on the types of costs that are allowable in establishing prices for goods provided under U.S. government contracts. The pricing for non-U.S. government contracts is based on the specific negotiations with each customer.

Our fixed-price contracts with the U.S. government or other customers may result in revenue recognized in excess of amounts currently billed. We disclose the excess of revenues over amounts actually billed as Contract assets and unbilled receivables on the balance sheet. Amounts billed and due from our customers are classified as Accounts receivable on the balance sheets. In some instances, the U.S. government retains a small portion of the contract price until completion of the contract. The portion of the payments retained until final contract settlement is not considered a significant financing component because the intent is to protect the customer. For contracts with the U.S. government, we typically receive interim payments either as work progresses or by achieving certain milestones or based on a schedule in the contract. We recognize a liability for these advance payments in excess of revenue recognized and present it as Contract liabilities and billings in excess of revenue earned on the balance sheets. The advanced payment typically is not considered a significant financing component because it is used to meet working capital demands that can be higher in the early stages of a contract and to protect us from the other party failing to adequately complete some or all of its obligations under the contract. For industrial and consumer purchase orders, we typically receive payments within 30 to 60 days of shipments of the product, although for some purchase orders, we may require an advanced payment prior to shipment of the product.

To determine the proper revenue recognition method for contracts with the same customer, we evaluate whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. For most of our development contracts and contracts with the U.S government, the customer contracts with us to provide a significant service of integrating a set of components into a single unit. Hence, the entire contract is accounted for as one performance obligation. Less frequently, however, we may promise to provide distinct goods or services within a contract in which case we separate the contract into more than one performance obligation. If a contract is separated into more than one performance obligation, we allocate the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. In cases where we sell standard products, the observable standalone sales are used to determine the standalone selling price.

The Company recognizes revenue from a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

For certain contracts with the U.S. government, the Company recognizes revenue over time as we perform because of continuous transfer of control to the customer and the lack of an alternative use for the product. The continuous transfer of control to the customer is supported by liability clauses in the contract that allow the U.S. government to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any work in process. For contracts with commercial customers, while the contract may have a similar liability clause, our products historically have an alternative use and thus, revenue is recognized at a point in time.

In situations where control transfers over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. We generally use the cost-to-cost approach to measure the extent of progress towards completion of the performance obligation for our contracts because we believe it best depicts the transfer of assets to the customer. Under the cost-to-cost measure approach, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred.

Accounting for design, development and production contracts requires judgment relative to assessing risks, estimating contract revenues and costs, and making assumptions for schedule and technical issues. Due to the size and nature of the work required to be performed on many of our contracts, the estimation of total revenue and cost at completion is complicated and subject to many variables. Contract costs include material, labor and subcontracting costs, as well as an allocation of indirect costs. We have to make assumptions regarding the number of labor hours required to complete a task, the complexity of the work to be performed, the availability and cost of materials, and performance by our subcontractors. For contract change orders, claims or similar items, we apply judgment in estimating the amounts and assessing the potential for realization. These amounts are only included in contract value when they can be reliably estimated and realization is considered probable. If our estimate of total contract costs or our determination of whether the customer agrees that a milestone is achieved is incorrect, our revenue could be overstated or understated and the profits or loss reported could be subject to adjustment.

For our commercial customers, the Company's revenue is recognized when obligations under the terms of a contract with our customer is satisfied and the Company transfers control of the products or services, which is generally upon delivery to the customer. Revenue is recorded as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Provisions for product returns and allowances are reductions in the transaction price and are recorded in the same period as the related revenues. We analyze historical returns, current economic trends and changes in customer demand when evaluating the adequacy of sales returns and other allowances. Certain product sales are made to distributors under agreements allowing for a limited right of return on unsold products. Sales to distributors are primarily made for sales to the distributors' customers and not for stocking of inventory. Sales, value add and other taxes we collect concurrent with revenue-producing activities are excluded from revenue.

The rights and benefits to the Company's intellectual property are conveyed to certain customers through technology license agreements. These agreements may include other performance obligations including the sale of product to the customer. When the license is distinct from other obligations in the agreement, the Company treats the license and other performance obligations as separate performance obligations. Accordingly, the license is recognized at a point in time or over time based on the standalone selling price. The sale of materials is recognized at a point in time, which occurs with the transfer of control of the Company's products or services. In certain instances, the Company is entitled to sales-based royalties under license agreements. These sales-based royalties are recognized when they are earned. Revenues from sales-based royalties under license agreements are shown under Research and development and other revenues on the Company's Consolidated Statements of Operations.

Revenue Recognition - 2017

We recognize revenue if four basic criteria have been met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred and services rendered; (3) the price to the buyer is fixed or determinable; and (4) collectability is reasonably assured. We do not recognize revenue for products prior to customer acceptance unless we believe the product meets all customer specifications and has a history of consistently achieving customer acceptance of the product. Provisions for product returns and allowances are recorded in the same period as the related revenues. We analyze historical returns, current economic trends and changes in customer demand and acceptance of product when evaluating the adequacy of sales returns and other allowances. Certain product sales are made to distributors under agreements allowing for a limited right of return on unsold products. Sales to distributors are primarily made for sales to the distributors' customers and not for stocking of inventory. We delay revenue recognition for our estimate of distributor claims of right of return on unsold products based upon our historical experience with our products and specific analysis of amounts subject to return based upon discussions with our distributors or their customers.

We recognize revenues from long-term research and development government contracts on the percentage-of-completion method of accounting as work is performed, based upon the ratio of costs or hours already incurred to the estimated total cost of completion or hours of work to be performed. Revenue recognized at any point in time is limited to the amount funded by the U.S. government or contracting entity. We recognize revenue for product development and research contracts that have established prices for distinct phases when delivery and acceptance of the deliverable for each phase has occurred. In some instances, we are contracted to create a deliverable which is anticipated to go into full production. In those cases, we discontinue the percentage-of-completion method after formal qualification of the deliverable has been completed and revenue is then recognized based on the criteria established for sale of products. In certain instances, qualification may be achieved and delivery of production units may commence however our customer may have either identified new issues to be resolved or wish to incorporate a newer display technology. In these circumstances new units delivered will continue to be accounted for under the criteria established for sale of products. Under certain of our research and development contracts, we recognize revenue using a milestone methodology. This revenue is recognized when we achieve specified milestones based on our past performance.

We classify amounts earned on contracts in progress that are in excess of amounts billed as unbilled receivables and we classify amounts received in excess of amounts earned as billings in excess of revenues earned. We invoice based on dates specified in the related agreement or in periodic installments based upon our invoicing cycle. We recognize the entire amount of an estimated ultimate loss in our financial statements at the time the loss on a contract becomes known.

Accounting for design, development and production contracts requires judgment relative to assessing risks, estimating contract revenues and costs, and making assumptions for schedule and technical issues. Due to the size and nature of the work required to be performed on many of our contracts, the estimation of total revenue and cost at completion is complicated and subject to many variables. Contract costs include material, labor and subcontracting costs, as well as an allocation of indirect costs. We have to make assumptions regarding the number of labor hours required to complete a task, the complexity of the work to be performed, the availability and cost of materials, and performance by our subcontractors. For contract change orders, claims or similar items, we apply judgment in estimating the amounts and assessing the potential for realization. These amounts are only included in contract value when they can be reliably estimated and realization is considered probable. We have accounting policies in place to address these as well as other contractual and business arrangements to properly account for long-term contracts. If our estimate of total contract costs or our determination of whether the customer agrees that a milestone is achieved is incorrect, our revenue could be overstated and profits would be negatively impacted.

Research and Development Costs

Research and development expenses are incurred in support of internal display product development programs or programs funded by agencies or prime contractors of the U.S. government and commercial partners. Research and development costs include staffing, purchases of materials and laboratory supplies, circuit design costs, fabrication and packaging of experimental display products, and overhead, and are expensed immediately.

Cash and Cash Equivalents

The Company considers all highly liquid, short-term debt instruments with original maturities of three months or less to be cash equivalents.

Inventory

Inventories are stated at standard cost adjusted to approximate the lower of cost (first-in, first-out method) or net realizable value. The Company adjusts inventory carrying value for estimated obsolescence equal to the difference between the cost of inventory and the estimated net realizable value based upon assumptions about future demand and market conditions. The Company fully reserves for inventories and non-cancellable purchase orders for inventory deemed obsolete. The Company performs periodic reviews of inventory items to identify excess inventories on hand by comparing on-hand balances to anticipated usage using recent historical activity as well as anticipated or forecasted demand. If estimates of customer demand diminish further or market conditions become less favorable than those projected by the Company, additional inventory adjustments may be required.

We regularly review inventory quantities on-hand and we write down inventory based on excess or obsolete inventories determined primarily by future anticipated demand for our products. Inventory write-downs are measured as the difference between the cost of the inventory and net realizable value, based upon assumptions about future demand, which are inherently difficult to assess and dependent on market conditions. At the point of a loss 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 basis.

Inventory consists of the following at December 28, 2019 and December 29, 2018:



	2019		2018
Raw materials	$	2,630,156	$	2,548,139
Work-in-process	711,475		1,526,552
Finished goods	427,065		722,547
	$	3,768,696	$	4,797,238

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the assets, generally 3 to 10 years. Leasehold improvements and leased equipment are amortized over the shorter of the term of the lease or the useful life of the improvement or equipment. As discussed below,

obligations for asset retirement are accrued at the time property, plant and equipment is initially purchased or as such obligations are generated from use.

Product Warranty

The Company generally sells products with a limited warranty of product quality and a limited indemnification of customers against intellectual property infringement claims related to the Company’s products. The Company accrues for known warranty and indemnification issues if a loss is probable and can be reasonably estimated and accrues for estimated incurred but unidentified issues based on historical activity. Accrued warranty costs and warranty claims are not material in the periods presented.

Asset Retirement Obligations

The Company recorded asset retirement obligations ("ARO") liabilities of $0.3 million at December 28, 2019 and December 29, 2018. This represents the legal obligations associated with retirement of the Company’s assets when the timing and/or method of settling the obligation are conditional on a future event that may or may not be within the control of the Company. Changes in ARO liabilities for fiscal years 2019 and 2018 are as follows:



	2019		2018
Beginning balance	$	254,098	$	269,877
Exchange rate change	7,785		(15,779		)
Ending balance	$	261,883	$	254,098

Income Taxes

The consolidated financial statements reflect provisions for federal, state, local and foreign income taxes. The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, as well as operating loss and tax credit carryforwards. The Company measures deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company provides valuation allowances if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

Foreign Currency

Assets and liabilities of non-U.S. operations where the functional currency is other than the U.S. dollar are translated from the functional currency into U.S. dollars at year end exchange rates, and revenues and expenses are translated at average rates prevailing during the year. Resulting translation adjustments are accumulated as part of accumulated other comprehensive income. Transaction gains or losses are recognized in income or loss in the period in which they occur.

Net (Loss) Income Per Share

Net Loss Per Share

Basic net loss per share is computed using the weighted-average number of shares of common stock outstanding during the period less any unvested restricted shares. Diluted net loss per share is calculated using weighted-average shares outstanding and contingently issuable shares, less weighted-average shares reacquired during the period. The net outstanding shares are adjusted for the dilutive effect of shares issuable upon the assumed conversion of the Company’s common stock equivalents, which consist of outstanding stock options and unvested restricted stock.

The following were not included in weighted-average common shares outstanding-diluted because they are anti-dilutive:



	2019	2018	2017
Nonvested restricted common stock	1,863,124	2,213,249	2,629,274

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk other than marketable securities consist principally of trade accounts receivable. Trade receivables are primarily derived from sales to manufacturers of consumer electronic devices and wireless components or military applications. The Company sells its products to customers worldwide and generally does not require collateral. The Company maintains a reserve for potential credit losses.

The Company primarily invests its excess cash in government backed and corporate debt securities that management believes to be of high credit worthiness, which bear lower levels of relative credit risk. The Company relies on rating agencies to ascertain the credit worthiness of its marketable securities and, where applicable, guarantees made by the Federal Deposit Insurance Company.

Fair Value of Financial Instruments

Marketable Securities, Policy [Policy Text Block]

Other-than-Temporary Impairments

The Company conducts a review of its marketable debt securities on a quarterly basis for the presence of other-than-temporary impairment ("OTTI"). The Company assesses whether OTTI is present when the fair value of a debt security is less than its amortized cost basis at the balance sheet date. Under these circumstances OTTI is considered to have occurred (1) if the Company intends to sell the security before recovery of its amortized cost basis; (2) if it is “more likely than not” the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not sufficient to recover the entire amortized cost basis.

The Company further estimates the amount of OTTI resulting from a decline in the creditworthiness of the issuer (credit-related OTTI) and the amount of non credit-related OTTI. Non credit-related OTTI can be caused by such factors as market illiquidity. Credit-related OTTI is recognized in earnings while non credit-related OTTI on securities not expected to be sold is recognized in other comprehensive income (loss). The Company did not record any OTTI for the fiscal years 2019, 2018 and 2017.

Stock-Based Compensation

The fair value of nonvested restricted common stock awards is generally the quoted price of the Company’s equity shares on the date of grant. The nonvested restricted common stock awards require the employee to fulfill certain obligations, including remaining employed by the Company for one, two or four years (the vesting period) and in certain cases also require meeting either performance criteria or market condition. The performance criteria primarily consist of the achievement of established milestones. For nonvested restricted common stock awards which solely require the recipient to remain employed with the Company, the stock compensation expense is amortized over the anticipated service period. For nonvested restricted common stock awards which require the achievement of performance criteria, the Company reviews the probability of achieving the performance goals on a periodic basis. If the Company determines that it is probable that the performance criteria will be achieved, the amount of compensation cost derived for the performance goal is amortized over the service period. If the performance criteria are not met, no compensation cost is recognized, and any previously recognized compensation cost is reversed. The Company recognizes compensation costs on a straight-line basis over the requisite service period for time vested awards.

The value of restricted stock grants that vest based on market conditions is computed on the date of grant using the Monte Carlo model. The fair value of stock option awards is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. There were no stock options granted in fiscal years 2019, 2018 or 2017.

Comprehensive Income, Policy [Policy Text Block]

Comprehensive Loss

Comprehensive loss is the total of net (loss) income and all other non-owner changes in equity including such items as unrealized holding (losses) gains on marketable equity and debt securities classified as available-for-sale and foreign currency translation adjustments.

The components of accumulated other comprehensive income are as follows:



	Cumulative Translation Adjustment			Unrealized holding (loss) gain on marketable securities			Reclassifications of gain (loss) of marketable securities in net loss			Accumulated Other Comprehensive Income
Balance as of December 31, 2016	$	1,380,042		$	239,213		$	(48,284	)	$	1,570,971
Changes during year	1,851,664			148,520			(6,376		)	1,993,808
Balance as of December 30, 2017	3,231,706			387,733			(54,660		)	3,564,779
Changes during year	(1,794,768		)	(264,949		)	49,525			(2,010,192		)
Balance as of December 29, 2018	1,436,938			122,784			(5,135		)	1,554,587
Changes during year	(206,580		)	446,533			(37,356		)	202,597
Balance as of December 28, 2019	$	1,230,358		$	569,317		$	(42,491	)	$	1,757,184

Impairment Long-Lived Assets

Impairment of Long-Lived Assets

The Company periodically reviews the carrying value of its long-lived assets to determine if facts and circumstances suggest that they may be impaired or that the amortization or depreciation period may need to be changed. The carrying value of a long-lived asset is considered impaired when the anticipated identifiable undiscounted cash flows from such asset are less than its carrying value. For assets that are to be held and used, impairment is measured based upon the amount by which the carrying amount of the asset exceeds its fair value.

Recently Adopted Accounting Pronouncements

Leases

Effective December 30, 2018 (the first day of fiscal year 2019), the Company adopted the requirements of the new lease standard Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842) using the modified retrospective approach, applying the new lease requirements at the beginning of fiscal year 2019. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which, among other things, allows us to carry forward the historical lease classification. The Company did not elect the practical expedient to use hindsight in determining the lease term and in assessing impairment of right-of-use assets. The standard resulted in the recognition of operating lease right-of-use assets of $3.7 million and operating lease liabilities of $3.8 million, of which $1.0 million was classified as current at the beginning of fiscal year 2019. The standard had no material impact on the Company's results of operations or cash flows and there was no cumulative impact on accumulated deficit as of December 30, 2018. In addition, new disclosures are provided to enable readers to assess the amount, timing and uncertainty of cash flows arising from leases.

The Company determines if an arrangement is a lease or contains an embedded lease at inception. For lease arrangements with both lease and non-lease components (e.g., common-area maintenance costs), the Company accounts for the non-lease components separately.

All of the Company's leases are operating leases. Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of future lease payments over the lease term at the commencement date. The operating lease right-of-use assets also includes any initial direct costs and any lease payments made at or before the commencement date and is reduced for any unrestricted incentives received at or before the commencement date.

For the majority of the Company's leases, the discount rate used to determine the present value of the lease payments is the Company's incremental borrowing rate at the lease commencement date, as the implicit rate is not readily determinable. The discount rate represents a risk-adjusted rate on a secured basis and is the rate at which the Company would borrow funds to satisfy the scheduled lease liability payment streams commensurate with the lease term. On December 30, 2018, the discount rate used on existing leases at adoption was determined based on the remaining lease term using available data as of that date. For new or renewed leases starting in 2019, the discount rate is determined using available data at lease commencement and based on the lease term including any reasonably certain renewal periods.

Some of our leases include options to extend or terminate the lease. The Company includes these options in the recognition of the Company's ROU assets and lease liabilities when it is reasonably certain that the Company will exercise the option. In most cases, the Company has concluded that renewal and early termination options are not reasonably certain of being exercised by the Company (and thus not included in our ROU asset and lease liability) unless there is an economic, financial or business reason to do so. None of our leases include variable lease-related payments, such as escalation clauses based on the consumer price index ("CPI") rates or residual guarantees.
