Summary of Significant Accounting Policies |
Basis of Presentation | Basis of Presentation The accompanying Consolidated Financial Statements include the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents and they are stated at cost, which approximates fair value.
Trade Accounts Receivable and Concentration of Credit Risk | Trade Accounts Receivable and Concentration of Credit Risk Accounts receivable are stated at the amount management expects to collect from outstanding balances. The Company performs ongoing credit evaluations of its customers and generally requires no collateral to secure accounts receivable.
|  | December 31, 2018 |  | December 31, 2017
Trade accounts receivable |  | $ | 36,428 |  | $ | 32,579

Less allowance for doubtful accounts |  |  | (211) |  |  | (48)
|  | $ | 43,794 |  | $ | 32,531
The Company maintains an allowance for potentially uncollectible accounts receivable based upon its assessment of the collectability of accounts receivable. Accounts are written off against the allowance when it is determined collection will not occur. The allowance for bad debt and credit activity for the years ended December 31, 2018 and 2017 is summarized as follows:
Balance as of December 31, 2016 |  | $ | 124 |
Bad debt expense |  |  | 4 |
Write-off of uncollectible accounts |  |  | (82) |
Currency translation adjustments |  |  | 2 |
Balance as of December 31, 2017 |  | $ | 48 |
Bad debt expense |  |  | 169 |
Write-off of uncollectible accounts |  |  | (6) |
Balance as of December 31, 2018 |  | $ | 211 |
For the year ended December 31, 2018 one customer represented 19% of the Company’s consolidated net sales. For the year ended December 31, 2017 one customer represented 15% of the Company’s consolidated net sales.
Inventories | Inventories Inventories consist of raw materials, and finished goods and are measured at the lower of cost or net realizable value (determined on the first-in, first-out, specific identification or weighted-average method basis). Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.
Plant, Equipment and Leasehold Improvements | Plant, Equipment and Leasehold Improvements Plant, equipment and leasehold improvements are recorded at cost. Accumulated depreciation is computed using the straight-line method over the lesser of the estimated useful life of the related assets (generally 3 to 10 years for machinery and equipment, furniture, computer equipment, and leasehold improvements) or, when applicable, the lease term. Maintenance and repairs that do not extend the useful life of the respective assets are charged to expense as incurred. Long-lived assets with finite lives are reviewed for impairment whenever events indicate that the carrying amount of the asset or the carrying amounts of the asset group containing the asset may not be recoverable. In such reviews, estimated undiscounted future cash flows associated with these assets or asset groups are compared with their carrying value to determine if a write-down to fair value is required.
Goodwill and Intangible Assets | Goodwill and Intangible Assets Goodwill is not amortized, but instead is tested for impairment at least annually on October 1 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable. For impairment evaluations, the Company first makes a qualitative assessment with respect to both goodwill and other indefinite-lived intangibles. During 2017, the Company early adopted ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”) in conjunction with its annual impairment testing effective October 1, 2017. In accordance with ASU 2017-04, an entity should perform its goodwill impairment test by comparing the fair value of the reporting unit with its carrying amount, and recognize an impairment charge for the amount by which the carrying amount of the reporting unit exceeds its fair value. The Company generally bases its measurement of the fair value of a reporting unit on a blended analysis of the present value of future discounted cash flows and the market valuation approach. The discounted cash flows model indicates the fair value of the reporting unit based on the present value of the cash flows that the Company expects the reporting unit to generate in the future. The Company's significant estimates in the discounted cash flows model include: its weighted average cost of capital; discrete and long-term rate of growth and profitability of the reporting unit's business; and working capital effects. The market valuation approach indicates the fair value of the business based on a comparison of the reporting unit to comparable publicly traded companies in similar lines of business. Significant estimates in the market valuation approach model include identifying similar companies with comparable business factors such as size, growth, profitability, risk and return on investment, and assessing comparable revenue and operating income multiples in estimating the fair value of the reporting unit. Acquired finite-lived intangible assets are amortized on a straight-line basis over the estimated useful lives of the assets, and are reviewed for impairment whenever events indicate that the carrying amount of the asset may not be recoverable. In such reviews, estimated undiscounted future cash flows associated with these assets are compared with their carrying value to determine if a write-down to fair value is required.
Income Taxes | Income Taxes The Company accounts for income taxes using an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. The Company has deferred tax assets and liabilities and maintains valuation allowances where it is more likely than not that all or a portion of deferred tax assets will not be realized. To the extent the Company determines that it will not realize the benefit of some or all of its deferred tax assets, then these deferred tax assets will be adjusted through the Company’s income tax expense in the period in which this determination is made. The Company recognizes the tax benefits from uncertain tax positions only when it is more likely than not, based on the technical merits of the position, that the tax position will be sustained upon examination, including the resolution of any related appeals or litigation. The tax benefits recognized in the consolidated financial statements from such a position are measured as the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense.
Stock-Based Compensation | Stock-Based Compensation The Company accounts for stock-based compensation pursuant to ASC 718, Share-Based Payments. All stock-based compensation to employees is required to be measured at fair value and expensed, net of forfeitures, over the requisite service period. The Company recognizes compensation expense on awards on a straight-line basis over the vesting period for each tranche of an award. Refer to Note 15 “Stock Based Compensation” for additional discussion regarding details of the Company's stock-based compensation plans.
Accrued Expenses | Accrued Expenses Accrued liabilities include accrued payroll expense of $2,371, and $2,526, as of December 31, 2018, and 2017, respectively. Accrued liabilities as of December 31, 2018, also includes accrued employee performance bonus of $7,137.
Use of Estimates | Use of Estimates The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These accounting principles require management to make assumptions and estimates relating to the reporting of assets and liabilities in its preparation of the Consolidated Financial Statements. Significant items subject to such estimates and assumptions include the carrying amount of property and equipment, goodwill and intangible assets, valuation allowances for inventories and deferred taxes, debt, uncertain tax positions and stock-based compensation expense. Actual results could differ from those estimates.
Foreign Currency Translation | Foreign Currency Translation Financial statements of foreign subsidiaries that use local currencies as their functional currency are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities and the weighted-average exchange rate for each reporting period for net sales, expenses, gains and losses. Translation adjustments are recorded as a component of Accumulated Other Comprehensive Loss in the accompanying consolidated financial statements. Foreign currency transaction gains and losses resulting from the process of re-measurement are recorded in “Foreign currency gain (loss)” in the accompanying Consolidated Statements of Operations and Comprehensive (Loss) Income. For the years ended December 31, 2018 and 2017 there were $(311) and $517 of such foreign currency (losses) gains, respectively.
Recently Accounting Pronouncements | Recently Accounting Pronouncements Recently Adopted Accounting Pronouncements As of January 1, 2018, the Company adopted Accounting Standards Codification ASC 606, Revenue from Contracts with Customers, (“ASC 606”), which requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASC 606 also requires an entity to disclose sufficient quantitative and qualitative information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted ASC 606 of January 1, 2018 to all its contracts using the modified retrospective method and recognized the cumulative effect of adoption as an adjustment to the opening balance of “Accumulated loss” on the Consolidated Balance Sheet. Under the new guidance, the Company recognizes certain performance obligations over time as the goods are produced, since those products provide value to only a specified customer, have no alternative use and the Company has the right to payment for work completed on such items. This accelerates the timing of revenue recognition for these arrangements, as revenue is recognized as goods are produced rather than upon shipment or delivery of goods. In addition, as a result of adopting the new guidance, the Company has recorded decreases to deferred revenue, and work in process and finished goods inventories, and an increase to accounts receivable. These changes are reflected in the adoption adjustments table below. The comparative financial information has not been restated and continues to be reported under the accounting standards in effect for those periods. See Note 3 “Net sales” for revenue recognition timing and methodology under ASC 606. The cumulative effects of the adjustments made to the Company’s January 1, 2018 Consolidated Balance Sheet upon adoption of ASC 606 were as follows:

During 2017, the Company early adopted ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”) in conjunction with its annual impairment testing effective October 1, 2017. In accordance with ASU 2017-04, an entity should perform its goodwill impairment test by comparing the fair value of the reporting unit with its carrying amount, and recognize an impairment charge for the amount by which the carrying amount of the reporting unit exceeds its fair value. Recently Issued Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASC Topic 842, Leases (“ASC 842”), which provides guidance for accounting for leases. The new guidance requires companies to recognize the assets and liabilities for the rights and obligations created by leased assets. ASC 842 is effective for annual and interim periods beginning after December 15, 2018 (the Company’s fiscal year 2019) with early adoption permitted. The new guidance requires the recognition and measurement of leases at the beginning of the earliest comparative period presented in the financial statements. The guidance required a modified retrospective approach, with an option to apply the transition provisions of the new guidance at the adoption date without adjusting the comparative periods presented. In July 2018, t he FASB issued additional accounting standard updates clarifying certain provisions, as well as providing for a second transition method allowing entities to initially apply the standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings. The Company will adopt the new guidance on the effective date of January 1, 2019 and use the adoption date as the date of initial application as allowed under ASC 842. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. The new standard provides a number of optional practical expedients in transition. The Company expects to elect the ‘package of practical expedients’, which permits the Company not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The Company does not expect to elect the use-of-hindsight transition practical expedient. The Company’s adoption process of ASC 842 is ongoing, including evaluating and quantifying the impact on the financial statements, identifying the population of leases, calculating its incremental borrowing rate and collecting and validating lease data. While the Company continues to assess all of the effects of adoption, the Company currently believes the most significant effects relate to the recognition of new right-of-use assets and lease liabilities on the balance sheet for real estate operating leases, and providing significant new disclosures about the Company’s leasing activities. The new standard also provides practical expedients for the Company’s ongoing accounting. The Company expects to elect the short-term lease recognition exemption for all leases that qualify, meaning the Company will not recognize right-of-use assets or lease liabilities for existing and new lease agreements that qualify. The Company also expects to elect the practical expedient to not separate lease and non-lease components for all of its leases.
