Summary of Significant Accounting Policies

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. As used in these notes, the terms “we,” “us,” “our,” “Kopin” and the “Company” mean Kopin Corporation and its subsidiaries, unless the context indicates another meaning.

Fiscal Year

The Company’s fiscal year ends on the last Saturday in December. The fiscal years ended December 30, 2017 includes 52 weeks, December 31, 2016 includes 53 weeks and December 26, 2015 includes 52 weeks, and are referred to as fiscal years 2017, 2016 and 2015, respectively, herein. The impact of the 53^rd week in the 2016 fiscal year was not material to the Company's results of operations.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, a majority owned 93% subsidiary, Kowon Technology Co., Ltd. ("Kowon"), located in Korea, and a majority owned 80% subsidiary, eMDT America Inc ("eMDT"), located in California (collectively the Company). In the fourth quarter of 2015, the Company increased its investment in Kopin Software Ltd. ("KSL") (formerly Intoware Ltd.) from 58% to 100%. 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

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 and Marketable Securities

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

Marketable debt securities consist primarily of commercial paper, medium-term corporate notes, and United States government and agency backed securities. The Company classifies these marketable debt securities as available-for-sale at fair value in “Marketable debt securities, at fair value”. The investment in GCS Holdings is included in "Other Assets" as available-for-sale and at fair value. The Company records the amortization of premium and accretion of discounts on marketable debt securities in the results of operations.

The Company uses the specific identification method as a basis for determining cost and calculating realized gains and losses with respect to marketable debt securities. The gross gains and losses realized related to sales of marketable debt securities were not material during fiscal years 2017, 2016 and 2015.

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 in the retail channels. 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 30, 2017 and December 31, 2016:



	2017		2016
Raw materials	$	2,070,153	$	1,986,491
Work-in-process	1,829,805		1,186,162
Finished goods	1,180,839		129,459
	$	5,080,797	$	3,302,112

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.

Collaborative Arrangements

The Company evaluates whether an arrangement is a collaborative arrangement under the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC”) Topic 808, Collaborative Arrangements, at its inception based on the facts and circumstances specific to the arrangement. The Company also reevaluates whether an arrangement qualifies or continues to qualify as a collaborative arrangement whenever there is a change in either the roles of the participants or the participants’ exposure to significant risks and rewards dependent on the ultimate commercial success of the endeavor. For those collaborative arrangements where it is determined that the Company is the principal participant, costs incurred and revenue generated from third parties are recorded on a gross basis in the financial statements.

From time to time, the Company enters into collaborative arrangements for the research and development, manufacture and/or commercialization of products. The Company’s collaboration agreements with third parties are performed on a ‘‘best efforts’’ basis with no guarantee of either technological or commercial success.

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.

Extended Warranties

Deferred revenue represents the purchase of extended warranties by the Company's customers. The Company recognizes revenue from an extended warranty on the straight-line method over the life of the extended warranty, which is typically 12 to 15 months beyond the standard 12 month warranty. The Company classifies the current portion of deferred revenue under other accrued liabilities in its consolidated balance sheets. The Company currently has $0.7 million of deferred revenue related to extended warranties at December 30, 2017.

Asset Retirement Obligations

The Company recorded asset retirement obligations ("ARO") liabilities of $0.3 million and $0.2 million at December 30, 2017 and December 31, 2016, respectively. 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 2017 and 2016 are as follows:



	2017		2016
Beginning balance	$	246,922	$	298,463
Exchange rate change	22,955		(51,541		)
Ending balance	$	269,877	$	246,922

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 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 or performance conditions have not been met at the end of the period:



	2017	2016	2015
Nonvested restricted common stock	2,629,274	3,007,674	2,192,016

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

Financial instruments consist of marketable debt securities, accounts receivable and certain current liabilities. These assets (excluding marketable securities which are recorded at fair value) and liabilities are carried at cost, which approximates fair value.

Marketable Debt Securities

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

Marketable debt securities consist primarily of commercial paper, medium-term corporate notes, and U.S. government and agency backed securities. The Company classifies these marketable debt securities as available-for-sale at fair value in “Marketable debt securities, at fair value”. The Company's investment in GCS Holdings is included in "Other Assets" as available-for-sale and at fair value. The Company records the amortization of premium and accretion of discounts on marketable debt securities in the results of operations.

The Company uses the specific identification method as a basis for determining cost and calculating realized gains and losses with respect to marketable debt securities. The gross gains and losses realized related to sales and maturities of marketable debt securities were not material during the year ended December 30, 2017 and December 31, 2016.

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 2017, 2016 and 2015.

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 2017, 2016 or 2015.

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 Gain (Loss) on Marketable Securities			Accumulated Other Comprehensive Income
Balance as of December 27, 2014	$	1,534,075		$	1,592,164		$	3,126,239
Changes during year	(968,050		)	(1,386,415		)	(2,354,465		)
Balance as of December 26, 2015	566,025			205,749			771,774
Changes during year	814,017			(14,820		)	799,197
Balance as of December 31, 2016	1,380,042			190,929			1,570,971
Changes during year	1,851,664			142,144			1,993,808
Balance as of December 30, 2017	$	3,231,706		$	333,073		$	3,564,779

Goodwill and Other Indefinite-Lived Assets

We account for goodwill in accordance with ASC Topic 350. Under ASC Topic 350, goodwill is considered to have an indefinite life, and is carried at cost. Acquired trade names are assessed as indefinite lived assets if there is no foreseeable limits on the periods of time over which they are expected to contribute cash flows. Goodwill and indefinite-lived assets are not amortized, but are subject to an annual impairment test, as well as between annual tests when events or circumstances indicate that the carrying value may not be recoverable. We perform our annual impairment testing at the end of each fiscal year.

Our annual goodwill impairment test is performed at the reporting unit level. We have determined our reporting units based on the guidance within ASC Subtopic 350-20. As of December 30, 2017 and December 31, 2016, our reporting units are the same as our operating segments. Indicators of impairment include, but are not limited to, the loss of significant business or other significant adverse changes in industry or market conditions. The Company reviews the carrying amounts of goodwill and other indefinite-lived assets annually, or when indications of impairment exist, to determine if such assets may be impaired by performing a quantitative assessment. We estimate the fair value of our reporting units using a discounted cash flow model based on our most recent long-range plan in place at the time of our impairment testing, and compare the estimated fair value of each reporting unit to its net book value, including goodwill. Significant changes in these forecasts or the discount rate selected could affect the estimated fair value of one or more of our reporting units and could result in a goodwill impairment charge in a future period.

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 Issued Accounting Pronouncements

Revenue from Contracts with Customers

The Company plans to adopt ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) effective December 31, 2017 (the first day of the Company's fiscal year 2018) and apply the modified retrospective method. This comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. The standard also requires expanded disclosures regarding revenue and contracts with customers.

The adoption of the new standard may have a material impact on the Company’s consolidated statement of operations and consolidated balance sheets. We currently expect that some of our military contracts that recognize revenue as products are shipped to customers will begin to recognize revenue under the new standard on a percentage of completion method using a cost to cost approach. This new approach may affect the timing of revenue and expense recognition and will rely more on management's judgments on the timing of revenue recognition and the timing and estimates of cost to fulfill contracts.

Upon the adoption of ASC 606 using the modified retrospective method on December 31, 2017, the Company will record an adjustment to accumulated deficit for the amount that would have been recognized in 2017 under the new guidance and would not have been recognized until shipment of the product in 2018 under the current guidance. The assessment of this adjustment under the new standard has been omitted from this Annual Report on Form 10-K because the assessment was incomplete as of the filing date. We are in the process of finalizing the results from the adoption and the adjustment under the new standard will be included in the Company's Quarterly Report on Form 10-Q for the first quarter of 2018. The new standard requires additional detailed disclosures regarding the Company’s contracts with customers, including disclosure of remaining unsatisfied performance obligations, in the first quarter 2018 which we are continuing to assess. We are also identifying and implementing changes to the Company’s business processes, systems and controls to support adoption of the new standard in 2018.

Leases

In February 2016, the FASB issued Accounting Standards Update No. 2016-02 (Topic 842) Leases. Topic 842 supersedes the lease recognition requirements in Accounting Standards Codification Topic 840, "Leases". Under Topic 842, lessees are required to recognize assets and liabilities on the balance sheet for most leases and provide enhanced disclosures. Leases will continue to be classified as either finance or operating. Topic 842 is effective for annual reporting periods, and interim periods within those years beginning after December 15, 2018. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, and there are certain optional practical expedients that an entity may elect to apply. Full retrospective application is prohibited and early adoption by public entities is permitted. The Company expects to complete its assessment in 2018 and is required to adopt ASU 2016-02 as of December 30, 2018 using the modified retrospective method. The Company expects the potential impact of adopting ASU 2016-02 to be material to our lease liabilities and assets on our consolidated balance sheets.

Classification of Certain Cash Receipts and Cash Payments

In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments (Topic 230). The standard addresses the classification and presentation of eight specific cash flow issues that currently result in diverse practices. This pronouncement is effective for annual reporting periods beginning after December 15, 2017. The Company will adopt this standard on December 31, 2017. The Company does not expect the potential impact of adopting ASU 2016-15 to be material to our financial position, results of operations or liquidity.

Intangibles - Goodwill and Other

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating “Step 2” from the goodwill impairment test. The amendment also eliminates the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company has adopted this amendment in its test of goodwill impairment for the fiscal year ended December 30, 2017.

Stock Compensation

In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting (ASU 2017-09), which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award changes as a result of the change in terms or conditions. The amendments in this ASU also clarify that no new measurement date will be required if an award is not probable of vesting at the time a change is made and there is no change to the fair value, vesting conditions, and classification. The amendments in this ASU are effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those annual periods. We intend to adopt the standard prospectively after the effective date and have determined this ASU has an immaterial impact to our financial position, results of operations or liquidity.
