The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary in Taiwan during 2019. All significant inter-company balances and transactions have been eliminated. Unless indicated otherwise, the information in the Notes to the Consolidated Financial Statements relates to our operations.

We have prepared the accompanying financial data for the three and six months ended June 30, 2020 and 2019 pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. The accompanying financial data and information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2019 (“2019 Annual Report”). The Condensed Consolidated Balance Sheet as of December 31, 2019 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

In the opinion of management, the accompanying condensed consolidated financial statements contain all normal and recurring adjustments necessary to present fairly our Condensed Consolidated Balance Sheets as of June 30, 2020 and December 31, 2019, Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2020 and 2019, Condensed Consolidated Statements of Comprehensive Loss for the three and six months ended June 30, 2020 and 2019, Condensed Consolidated Statements of Changes in Stockholders’ Equity for the three and six months ended

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact us in the future, actual results may vary from the estimates. Estimates include, but are not limited to, the establishment of reserves for accounts receivable, sales returns, inventory obsolescence and warranty claims; the useful lives of property and equipment; valuation allowance for net deferred taxes; the cost and offsetting income related to subleased property; and stock-based compensation. In addition, estimates and assumptions associated with the determination of the fair value of financial instruments and evaluation of long-lived assets for impairment requires considerable judgment. Actual results could differ from those estimates and such differences could be material.

For the three months ended June 30, 2020, sales to our primary distributor for the U.S. Navy, a regional commercial lighting retrofit company and a primary shipbuilder for the U.S. Navy, accounted for approximately 40%, 15% and 11% of net sales, respectively. When sales to our primary distributor for the U.S. Navy are combined with sales to shipbuilders for the U.S. Navy, total net sales of products for the U.S. Navy comprised approximately 60% of net sales for the same period. For the three months ended June 30, 2019, sales to our primary distributor for the U.S. Navy and a regional commercial lighting retrofit company accounted for approximately 13% and 26% of net sales, respectively. When sales to our primary distributor for the U.S. Navy are combined with sales to shipbuilders for the U.S. Navy, total net sales of products for the U.S. Navy comprised approximately 20% of net sales for the same period.

For the six months ended June 30, 2020, sales to our primary distributor for the U.S. Navy and a regional commercial lighting retrofit company accounted for approximately 39% and 15% of net sales, respectively. When sales to our primary distributor for the U.S. Navy are combined with sales to shipbuilders for the U.S. Navy, total net sales of products for the U.S. Navy comprised approximately 53% of net sales for the same period. For the six months ended June 30, 2019, sales to our primary distributor for the U.S. Navy and a regional commercial lighting retrofit company accounted for approximately 17% and 28% of net sales, respectively. When sales to our primary distributor for the U.S. Navy are combined with sales to shipbuilders for the U.S. Navy, total net sales of products for the U.S. Navy comprised approximately 26% of net sales for the same period.

A regional commercial lighting retrofit company and our primary distributor for the U.S. Navy accounted for approximately 19% and 47% of net trade accounts receivable, respectively, at June 30, 2020. At December 31, 2019, our primary distributor for the U.S. Navy accounted for approximately 10% of net trade accounts receivable and a large regional retrofit company accounted for 41% of our net trade accounts receivable.

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which significantly changes the accounting for credit losses on instruments within its scope. The new guidance introduces an approach based on expected losses to estimate credit losses on certain financial instruments, including trade receivables, and requires an entity to recognize an allowance based on its estimate of expected credit losses rather than incurred losses. For smaller reporting companies, this standard will be effective for interim and annual periods starting after December 15, 2022 and will generally require adoption on a modified retrospective basis. We are in the process of evaluating the impact of the standard.

Net sales include revenues from sales of products and shipping and handling charges, net of estimates for product returns. Revenue is measured at the amount of consideration we expect to receive in exchange for the transferred products. We recognize revenue at the point in time when we transfer the promised products to the customer and the customer obtains control over the products. Distributors’ obligations to us are not contingent upon the resale of our products. We recognize revenue for shipping and handling charges at the time the goods are shipped to the customer, and the costs of outbound freight are included in cost of sales. We provide for product returns based on historical return rates. While we incur costs for sales commissions to our sales employees and outside agents, we recognize commission costs concurrent with the related revenue, as the amortization period is less than one year. We do not incur any other incremental costs to obtain contracts with our customers. Our product warranties are assurance-type warranties, which promise the customer that the products are as specified in the contract. Therefore, the product warranties are not a separate performance obligation and are accounted for as described below. Sales taxes assessed by governmental authorities are accounted for on a net basis and are excluded from net sales.

Our trade accounts receivable consists of amounts billed to and currently due from customers. Our customers are concentrated in the United States. In the normal course of business, we extend unsecured credit to our customers related to the sale of our products. Credit is extended to customers based on an evaluation of the customer’s financial condition and the amounts due are stated at their estimated net realizable value. During the first eleven months of 2019 we evaluated and monitored the creditworthiness of each customer on a case-by-case basis. However, during December 2019 we transitioned to an account receivable insurance program with a high credit worthy insurance company where we have the large majority of the accounts receivable insured with a portion of self-retention. This third party also provides credit-worthiness ratings and metrics that significantly assists us in evaluating the credit worthiness of both existing and new customers. We maintain allowances for sales returns and doubtful accounts receivable to provide for the estimated number of account receivables that will not be collected. The allowance is based on an assessment of customer creditworthiness and historical

payment experience, the age of outstanding receivables, and performance guarantees to the extent applicable. Past due amounts are written off when our internal collection efforts have been unsuccessful, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. We do not generally require collateral from our customers.

Our standard payment terms with customers are net 30 days from the date of shipment, and we do not generally offer extended payment terms to our customers, but exceptions are made in some cases to certain customers or with particular orders. Accordingly, we do not adjust trade accounts receivable for the effects of financing, as we expect the period between the transfer of product to the customer and the receipt of payment from the customer to be in line with our standard payment terms.

All of our long-lived fixed assets are located in the United States. Sales attributable to customers outside the United States for both the three and six months ended June 30, 2020 were less than 1% of net sales. There were no net sales attributable to customers outside the United States for the three months ended June 30, 2019 and less than 1% for the six months ended June 30, 2019. The geographic location of our net sales is derived from the destination to which we ship the product.

Basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding during the period, excluding the effects of any potentially dilutive securities. Diluted loss per share gives effect to all dilutive potential common shares outstanding during the period. Dilutive potential common shares consist of incremental shares upon the exercise of stock options and warrants, unless the effect would be anti-dilutive.

As a result of the net loss we incurred for three and six months ended June 30, 2020, options, warrants and convertible securities representing approximately 47 thousand and 4 thousand shares of common stock were excluded from the loss per share calculation, respectively, because their inclusion would have been anti-dilutive. As a result of the net loss we incurred for the three and six months ended June 30, 2019, options, warrants and convertible securities representing approximately 28 thousand and 66 thousand shares of common stock were excluded from the loss per share calculation, respectively, because of this same reason.

Through March 31, 2016, we warranted finished goods against defects in material and workmanship under normal use and service for periods generally between one and five years. Beginning April 1, 2016, we warrant our commercial Tubular LED Lamps, (“TLEDs”), excluding RedCap^®, our Battery Backup TLED, the troffer luminaires, and certain Globe Lights for a period of ten years and all other LED products for five years per the Terms and Conditions outlined on our website. Beginning in October 2019, TLEDs (excluding Red Caps^®) are warranted for ten years and the warranty for all of our other products is five years. Warranty settlement costs consist of actual amounts expensed for warranty, which are largely a result of the cost of replacement products provided to our customers. A liability for the estimated future costs under product warranties is maintained for products under warranty based on the actual claims incurred to date and the estimated nature, frequency, and costs of future claims. These estimates are inherently uncertain and changes to our historical or projected experience may cause material changes to our warranty reserves in the future. We continuously review the assumptions related to the adequacy of our warranty reserve, including product failure rates, and make adjustments to the existing warranty liability when there are changes to these estimates or the underlying replacement product costs, or the warranty period expires. The following table summarizes warranty activity for the periods presented (in thousands):

In January 2020, we completed a registered direct offering for the sale of 688,360 shares of our common stock to certain institutional investors, at a purchase price of $3.37 per share. We also sold, to the same institutional investors, warrants to purchase up to 688,360 shares of common stock at an exercise price of $3.37 per share in a concurrent private placement for a purchase price of $0.625 per warrant. We paid the placement agent commissions of $193 thousand plus $50 thousand in expenses in connection with the registered direct offering and the concurrent private placement and we also paid legal, accounting and other fees of $231 thousand related to the offering. Total offering costs of $474 thousand have been presented as a reduction of additional paid-in capital and have been netted within equity. In addition, we issued warrants to the placement agent to purchase up to 48,185 shares of common stock at an exercise price of $4.99 per share. Net proceeds to us from the sale of common stock and warrants (the “January 2020 Equity Offering”) were approximately $2.3 million. In accordance with the terms of the Iliad Note (as defined below in Note 7), 10% of the gross proceeds from the January 2020 Equity Offering ($275 thousand) were used to make payments on the Iliad Note, of which $226 thousand went towards the outstanding principal amount and the balance to interest.

Warrants to purchase an aggregate of 721,546 shares remain outstanding at June 30, 2020 with a weighted average exercise price of $3.48 per share. The exercise of warrants could provide us with cash proceeds of $2.5 million. During the six months ended June 30, 2020, 15 thousand warrants were exercised resulting in total proceeds of $51 thousand.

The warrants have been classified as liabilities, as opposed to equity, due to the potential adjustment to the exercise price that could result upon late delivery of the shares or potential cash settlement and are recorded at their fair values at each balance sheet date. Please also refer to Note 9, “Stockholder’s Equity”.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value, giving the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below. We classify the inputs used to measure fair value into the following hierarchy:


Level 1			Unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2			Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability.
Level 3			Unobservable inputs for the asset or liability.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In determining the appropriate levels, we perform a detailed analysis of the assets and liabilities whose fair value is measured on a recurring basis. We review and reassess the fair value hierarchy classifications on a quarterly basis. Changes from one quarter to the next related to the observability of inputs in a fair value measurement may result in a reclassification between fair value hierarchy levels. There were no reclassifications for all periods presented.

The estimated fair value of warrants accounted for as liabilities, representing a level 3 fair value measure, was determined on the issuance date and subsequently marked to market at each financial reporting date. We use the Black-Scholes valuation model to value the warrant liabilities at fair value. The fair value is estimated using the expected volatility based on our historical volatility and is determined using probability weighted-average assumptions, when appropriate.
