Accounting Policies [Abstract] |
Basis of presentation | Basis of presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary organized 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 nine months ended September 30, 2020 and 2019 pursuant to the rules and regulations of the United States Securities and Exchange Commission. 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 September 30, 2020 and December 31, 2019, Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2020 and 2019, Condensed Consolidated Statements of Comprehensive Loss for the three and nine months ended September 30, 2020 and 2019, Condensed Consolidated Statements of Changes in Stockholders’ Equity for the three and nine months ended September 30, 2020 and 2019, and Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2020 and 2019.
Use of estimates | Use of estimates 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 sub-leased 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.
Recent accounting pronouncements | Recent accounting pronouncements In June 2016, the Financial Accounting Standards Board issued Accounting Standard Update 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.
Revenue | Revenue 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.
Accounts Receivable | Accounts Receivable Our trade accounts receivable consist 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 creditworthiness ratings and metrics that significantly assist us in evaluating the creditworthiness of both existing and new customers. We maintain allowances for sales returns and doubtful accounts receivable to provide for the estimated number of accounts receivable 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.
Net loss per share | Net loss per share Basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period, excluding the effects of any potentially dilutive securities. Diluted loss per share gives effect to all dilutive potential shares of common stock outstanding during the period. Dilutive potential shares of common stock consist of incremental shares upon the exercise of stock options, warrants and convertible securities, unless the effect would be anti-dilutive.
Product warranties | Product warrantiesThrough 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”), the troffer luminaires, and certain Globe Lights for a period of ten years (excluding RedCap® and our Battery Backup TLEDs), and all other LED products for five years per the Terms and Conditions outlined on our website. Beginning in October 2019, TLEDs (excluding RedCap®) are primarily warranted for ten years, certain D-Series lamps are warranted for either ten years or five years based on the customer’s choice 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.
Fair Value of Financial Instruments | 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.
