Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies (a) Principles of Consolidation The consolidated financial statements include the accounts of the Company and all of its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. (b) Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the U.S. ("U.S. GAAP") 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results are likely to differ from those estimates, and such differences may be material to the consolidated financial statements. Significant items subject to such estimates and assumptions include revenue recognition, going concern assessment, useful lives of intangibles and long-lived assets, long-lived asset and goodwill impairment, allowance for doubtful accounts, and valuation of inventory. (c) Cash and Cash Equivalents The Company considers all highly liquid investments with a remaining maturity at date of purchase of three months or less to be cash equivalents. (d) Restricted Cash The Company entered into irrevocable letters of credit with four banks to secure obligations under lease agreements and performance based obligations. These letters of credit are secured by cash balances totaling $1,010 and $1,121 which are recorded in restricted cash on the consolidated balance sheet as of December 31, 2022 and 2021, respectively. (e) Accounts Receivable The Company generally extends credit to certain customers without requiring collateral. The Company provides an allowance for doubtful accounts based on management’s evaluation of the collectability of accounts receivable. Accounts receivable are written off when it is deemed uncollectible. Accounts receivable of $32 and $454 were written off during the years ended December 31, 2022 and 2021, respectively. (f) Inventory Inventory is stated at the lower of cost or net realizable value. Inventory costs include raw materials, inbound freight charges, warehousing costs, labor, and overhead expenses related to the Company’s manufacturing and processing facilities. Charges for excess and obsolete inventory are based on specific identification of obsolete inventory items and an analysis of inventory items approaching expiration date. The Company records estimated excess and obsolescence charges to cost of sales. The Company’s inventories are stated using the weighted average cost approach, which approximates actual costs. (g) Fair Value Measurements The carrying amounts of the Company’s financial instruments, which primarily include cash and cash equivalents, and restricted cash, accounts receivable, accounts payable and accrued expenses, approximate their fair values due to their short maturities. The fair value of the Company’s long-term debt is estimated by management to approximate $35,000 for both December 31, 2022 and 2021. The Company’s convertible debt is estimated by management to approximate $18,200 and $20,500 at December 31, 2022 and 2021, respectively. Management’s estimates are based on comparisons of the characteristics of the Company’s obligations, comparable ranges of interest rates on recently issued debt, and maturity. Such valuation inputs are considered a Level 3 measurement in the fair value valuation hierarchy. The accounting guidance defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the accounting guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1: Observable inputs such as quoted prices in active markets; Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. (h) Property and Equipment Property and equipment are carried at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets, except for leasehold improvements, which are depreciated straight-line over the shorter of the estimated useful life or the life of the lease. Major renewals and betterments are capitalized. Validation costs (including materials and labor) that are required to bring machinery to working condition are capitalized. Expenditures for repairs and maintenance and minor replacements are charged to expense as incurred. (i) Leases Lease arrangements are generally recognized at lease commitment. Operating lease right-of-use assets and liabilities are recognized at commencement based on the present value of lease payments over the lease term, except for leases with an initial term of 12 months or less, for which lease expense is recognized as incurred over the lease term. Right-of-use assets represent the Company’s right to use an underlying asset during the reasonably certain lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease terms may include options to extend or terminate the lease when its reasonably certain that the Company will exercise that option. The Company primarily uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Operating lease right-of-use assets include any lease payments related to initial direct costs and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. (j) Goodwill and Other Intangible Assets Goodwill is not amortized but is tested annually for impairment or more frequently if impairment indicators exist. For annual and interim goodwill impairment tests, the Company first assesses qualitative factors before performing a quantitative assessment of the fair value of a reporting unit. If it is determined on the basis of qualitative factors that the fair value of the reporting unit is more likely than not less than the carrying amount, a quantitative impairment test is required. The Company’s evaluation of goodwill completed on December 31, 2022 and 2021 resulted in no impairment losses. Definite-lived intangible assets consist of customer relationships, product technology, trade names, patents and trademarks and capitalized software which are amortized over their estimated useful lives. Costs to extend the lives of and renew patents and trademarks are capitalized when incurred. (k) Valuation of Long-Lived Assets Long-lived assets, including definite-lived intangible assets, are monitored and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of any such asset may not be recoverable. The determination of recoverability is based on an estimate of undiscounted cash flows expected to result from the use of an asset and its eventual disposition. The estimate of undiscounted cash flows is based upon, among other things, certain assumptions about expected future operating performance. The Company’s estimates of undiscounted cash flows may differ from actual cash flows. If the sum of the undiscounted cash flows is less than the carrying value of the asset, an impairment charge is recognized, measured as the amount by which the carrying value exceeds the fair value of the asset. The Company’s evaluation of long-lived assets for the years ended December 31, 2022 and 2021 resulted in no impairment losses. (l) Revenue Recognition The Company’s principal source of revenues is from the sale of its products. Revenue is recognized when control of the promised goods is transferred to the customer, in an amount that reflects the consideration expected to be entitled to in an exchange for those goods. Generally, these are met under the Company’s agreements with most customers upon product shipment. This includes sales to distributors, who sell the products to their customers, take title to the products and assume all risks of ownership at the time of shipment. The Company’s distributors are obligated to pay within specified terms regardless of when, if ever, they sell the products. Customers and distributors generally have the right to return or exchange products purchased from the Company for up to thirty days from the date of product shipment. At the end of each period, the Company determines the extent to which its revenues need to be reduced to account for expected returns and exchanges. Certain customers may receive volume rebates or discounts, which are accounted for as variable consideration. The Company estimates these amounts based on the expected amount to be provided to customers and reduces recognized revenues. The Company records deferred revenues when cash payments are received in advance of the transfer of goods. The Company accounts for taxes collected from customers and remitted to governmental authorities on a net basis. Accordingly, such amounts are excluded from revenues. Amounts billed to customers related to shipping and handling are included in revenues. Shipping and handling costs related to revenue producing activities are included in cost of sales. (m) Research and Development Research and development costs are expensed as incurred. (n) Stock-based Compensation Plans The Company recognizes compensation costs for all stock-based awards based upon each award’s estimated fair value as determined on the date of grant. The Company utilizes the Black-Scholes option-pricing model to determine the fair value of stock option awards. The assumptions used in estimating the fair value of stock-based compensation awards represent management’s estimate and involve inherent uncertainties and the application of management’s judgement. Compensation cost is recognized on a straight-line basis over the respective vesting period of the award. Adjustments for actual forfeitures are made in the period which they occur. (o) Advertising The Company expenses advertising costs as incurred. The Company incurred approximately $632 and $244 in advertising costs during the years ended December 31, 2022 and 2021, respectively. (p) Income Taxes The Company accounts for deferred income taxes using the asset and liability method. Under this method, deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future. Temporary differences are then measured using the enacted tax rates and laws. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that is more-likely than-not to be realized. Determining the appropriate amount of valuation allowance requires management to exercise judgment about future operations. In the ordinary course of business, there are many transactions for which the ultimate tax outcome is uncertain. The Company regularly assesses uncertain tax positions in each of the tax jurisdictions in which it has operations and accounts for the related consolidated financial statement implications. The amount of unrecognized tax benefits is adjusted when information becomes available or when an event occurs indicating a change is appropriate. The Company includes interest and penalties related to its uncertain tax positions as part of income tax expense. (q) Foreign Currency The Company translates foreign assets and liabilities at exchange rates in effect at the balance sheet dates, and the revenues and expenses using average rates during the year. The resulting foreign currency translation adjustments are recorded as a separate component of accumulated other comprehensive income in the accompanying consolidated balance sheets. Exchange rate fluctuations on short-term intercompany loans are included in other expense in the consolidated statement of operations and comprehensive loss. (r) Recent Accounting Pronouncements In August 2020, Accounting Standards Update (“ASU”) No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity was issued, which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. This ASU will become effective for the Company on January 1, 2024 and is not expected to have a material impact on the consolidated financial statements. In May 2021, ASU No. 2021-04, Issuer’s Accounting for Certain Modifications of Exchanges of Freestanding Equity-Classified Written Call Options was issued to clarify the accounting for modifications or exchanges of freestanding equity-classified written call options, such was warrants, that remain equity classified after modification or exchange. This ASU became effective for the Company on January 1, 2022 and did not have a material impact on the consolidated financial statements.
