Significant Accounting Policies | NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES Use of Estimates 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, liabilities, revenues and expenses, and disclosures of contingent assets, liabilities, and expenses at the date of the consolidated financial statements during the reporting period. Significant estimates made by management include, among others, the fair value of acquired net assets of CDI in August 2018, and Bressner Technology GmbH in October 2018, dissolution expenses for SkyScale, the allowance for doubtful accounts, fair value of stock options, recoverability of inventories and long-lived assets, and realizability of deferred tax assets. Actual results could differ from those estimates. Concentration Risks At times, deposits held with financial institutions may exceed the amount of insurance provided by the Federal Deposit Insurance Corporation (“FDIC”), which provides basic deposit coverage with limits up to $250,000 per owner. As of June 30, 2019, the Company had $4,062,257 in excess of the insurance limits. The Company has not experienced any such losses in these accounts. In Germany, the deposit insurance is €100,000 per bank, per customer. As of June 30, 2019, Bressner has €236,412 (US$268,798) on deposit with banks in excess of the insurance limits. In the three month periods ended June 30, 2019 and 2018, our top three customers represented approximately 52%, and 48% of sales, respectively, and approximately 44%, and 49% for the six month periods ended June 30, 2019 and 2018, respectively. The Company made purchases from three suppliers which represented approximately 20% and 48% of purchases for the three month periods ended June 30, 2019 and 2018, respectively, and approximately 29% and 45% for the six month periods ended June 30, 2019 and 2018, respectively Cash and Cash Equivalents Cash and cash equivalents consist of cash on deposit and money market accounts. The Company considers all highly liquid temporary cash investments with an initial maturity of six months or less when acquired to be cash equivalents. Management believes that the carrying amounts of cash equivalents approximate their fair value because of the short maturity period. Accounts Receivable Accounts receivable are presented at net realizable value. This value includes an appropriate allowance for estimated uncollectible accounts to reflect any loss anticipated on the trade accounts receivable and unbilled receivables. Unbilled receivables include costs and gross profit earned in excess of billings. The allowance for doubtful accounts is an estimate to cover the losses resulting from the inability of customers to make payments on their outstanding balances and unbilled receivables. In estimating the required allowance, management considers the overall quality and aging of the accounts receivable, specific customer circumstances, current economic trends, and historical experience with collections. At June 30, 2019 and December 31, 2018, the allowance for doubtful accounts was $14,727 and $13,403, respectively. Revenues earned in excess of related billings are recorded as an asset on the balance sheet as unbilled receivables. Unbilled receivables as of June 30, 2019 and December 31, 2018, were $81,826 and $65,127, respectively. Inventories Inventories are valued at the lower of cost or net realizable value determined on a first-in, first-out basis. The Company uses the average cost method for purposes of determining cost, which approximates the first-in, first-out method. The Company establishes reserves on its inventories to write-down the carrying value of its estimated obsolete or excess inventories to estimated net realizable value based upon observations of historical usage and assumptions about future demand and market conditions. In addition, the Company considers changes in the market value of components in determining the net realizable value of its inventory. Inventory reserves are not typically reversed until the specific inventories are sold or otherwise disposed. Actual demand, product mix and alternative usage may be lower than those that we project and this difference could have a material adverse effect on our gross margin if inventory write-downs beyond those initially recorded become necessary. Alternatively, if actual demand, product mix and alternative usage are more favorable than those we estimated at the time of such a write-down, our gross margin could be favorably impacted in future periods. Property and Equipment Property and equipment, other than leasehold improvements, are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets, generally from three to five years. Leasehold improvements are recorded at cost and are amortized using the straight-line method over the shorter of the remaining lease term or the estimated useful life of the related asset. Tooling and test equipment includes capitalized labor costs associated with the development of the related tooling and test equipment. Costs incurred for maintenance and repairs are expensed as incurred, and expenditures for major replacements and improvements are capitalized. Upon retirement or sale, the cost and related accumulated depreciation and amortization of disposed assets are removed from the accounts and any resulting gain or loss is included in other expense, net. Goodwill Goodwill represents the excess of the purchase price paid over the fair value of the net assets acquired in business combinations. Goodwill is not amortized but is tested for impairment at least annually or when we deem that a triggering event has occurred. The Company reviews goodwill for impairment annually on December 31 st During the six month period ended June 30, 2019, the Company performed a goodwill impairment test of goodwill and as a result of a short-fall in the actual overall financial performance of CDI as compared to plan, a recurring need for working capital, and a decrease in the Company’s stock price. As a result of this interim evaluation, the Company recorded an impairment loss to goodwill of $1,988,701 which was charged to operating expenses in the current period. During the year ended December 31, 2018, the Company recognized goodwill related to two business acquisitions as described in Note 3. Intangible Assets and Long-lived Assets We evaluate our intangible and long-lived assets for impairment when events or circumstances arise that indicate our intangible and long-lived assets may be impaired. Indicators of impairment include, but are not limited to, a significant deterioration in overall economic conditions, a decline in our market capitalization, the loss of significant business, significant decreases in funding for our contracts, or other significant adverse changes in industry or market conditions. The Company completed its qualitative assessment for impairment in December 2018 and determined that there was no impairment as of December 31, 2018. There were no events or circumstances that arose during the six month period ended June 30, 2019, that gave an indication of impairment, except as discussed in Note 3. There can be no assurance, however, that market conditions will not change or demand for the Company’s products will continue, which could result in an impairment of intangible and long-lived assets in the future. Revenue Recognition On January 1, 2019, the Company adopted the new accounting standard update ASC 606, Revenue from Contracts with Customers, which superseded nearly all existing revenue recognition guidance under GAAP, to all contracts using the modified retrospective method. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The Company’s performance obligations are satisfied over time as work is performed or at a point in time. The majority of the Company’s revenue is recognized at a point in time when products ship and control is transferred to the customer. The Company determines revenue recognition through the following steps: (1) identification of the contract with a customer; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when, or as, a performance obligation is satisfied. The Company’s contracts are executed through a combination of written agreements along with purchase orders with all customers including certain general terms and conditions. Generally, purchase orders entail products, quantities and prices, which define the performance obligations of each party and are approved and accepted by the Company. The Company’s contracts with customers do not include extended payment terms. Payment terms vary by contract type and type of customer and generally range from 30 to 60 days from invoice. Additionally, taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer and deposited with the relevant government authority, are excluded from revenue. The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring goods or services to the customer adjusted for estimated variable consideration, if any. Variable consideration may include discounts, rights of return, refunds, and other similar obligations. The Company allocates the transaction price to each distinct product and service based on its relative standalone selling price. The standalone selling price for products primarily involves the cost to produce the deliverable plus the anticipated margin and for services is estimated based on the Company’s approved list price. In the normal course of business, the Company does not accept product returns unless the items are defective as manufactured. The Company establishes provisions for estimated returns and warranties. In addition, the Company does not typically provide customers with the right to a refund and does not transact for noncash consideration. Customer agreements include one vendor managed inventory program. The Company recognizes revenue under this arrangement when (i) risks of ownership have passed to the customer; (ii) the customer's commitment to purchase the goods is fixed ; ' ; ' , ' ' The Company recorded revenue from product sales that are held in vendor managed inventory under these agreements of $3,674,366 and $1,923,450, for the three month periods ended June 30, 2019 and 2018, respectively, and $5,168,444 and $2,913,851, for the six month periods ended June 30, 2019 and 2018, respectively. Revenues on certain fixed-price contracts where we provide engineering services, prototypes and completed products are recognized over the contract term based on the percentage of completion or based upon milestones delivered that are provided during the period and compared to the total estimated development and milestone goals to be provided over the entire contract. These services require that we perform significant, extensive and complex design, development, modification or implementation of our customers’ systems. Performance will often extend over long periods of time, and our right to receive future payment depends on our future performance in accordance with the agreement. Recognized revenue using the percentage of completion accounting method was $166,573 and $0 during the three month periods ended June 30, 2019 and 2018, respectively, and $201,053 and $0 during the six month periods ended June 30, 2019 and 2018, respectively. The percentage-of-completion methodology involves recognizing probable and reasonably estimable revenue using the percentage of services completed, on a current cumulative cost to estimate total cost basis, using a reasonably consistent profit margin over the period. Due to the long-term nature of these projects, developing the estimates of costs often requires significant judgment. Factors that must be considered in estimating the progress of work completed and ultimate cost of the projects include, but are not limited to, the availability of labor and labor productivity, the nature and complexity of the work to be performed and the impact of delayed performance. If changes occur in delivery, productivity or other factors used in developing the estimates of costs or revenues, we revise our cost and revenue estimates, which may result in increases or decreases in revenues and costs, and such revisions are reflected in earnings in the period in which the revision becomes known. Related billings that are in excess of revenue earned are deferred and recorded as a liability on the balance sheet until the related services are provided. Deferred revenue was $49,436 and $133,995 as of June 30, 2019 and December 31, 2018, respectively. The Company recognizes revenues for non-refundable, upfront implementation fees on a straight-line basis over the period beginning with initiation of ongoing services through the end of the contract term. The Company’s operating segment revenues disaggregated by primary geographic market, which is determined based on a customer’s geographic location, for the three and six month period ended June 30, 2019 is as follows: For The Three Month Period ended June 30, 2019 For The Six Month Period ended June 30, 2019 Entity: Domestic International Total Domestic International Total Customized computers and flash arrays $ 5,109,661 $ 4,898,143 $ 10,007,804 $ 7,152,171 $ 8,085,719 $ 15,237,890 In-flight entertainment & connectivity 881,062 13,500 894,562 1,177,591 16,425 1,194,016 Value-added reseller with minimal customization 27,851 3,956,019 3,983,870 520,830 7,991,399 8,512,229 $ 6,018,574 $ 8,867,662 $ 14,886,236 $ 8,850,592 $ 16,093,543 $ 24,944,135 During the comparative 2018 periods, the Company only had one operating segment. Warranty Reserve The Company offers product warranties that extend for one year from the date of sale. Such warranties require the Company to repair or replace defective product returned to the Company during the warranty period at While such costs have historically been within management’s expectations and the provisions established, unexpected changes in failure rates could have a material adverse impact on the Company, requiring additional warranty reserves and could adversely affect the Company’s gross profit and gross margins. The Company offers customers extended warranties beyond the standard one-year warranty on the product. The customer can purchase extended warranties from one to five years, in the bronze, silver or gold categories. The revenue that was recognized for the warranties sold for the three months periods ended June 30, 2019 and 2018 was $104,474 and $31,747, respectively, and $211,172 and $59,195 for the six months periods ended June 30, 2019 and 2018, respectively. The Company does have recourse with some of its suppliers that offer more than a one-year guarantee on parts, but this is not standard. The few that offer greater than a year warranty, the Company may be able to cover the cost of the part from the manufacturer for the failed part. The amounts of these costs vary in a wide range, but are not material, due to the infrequency of failure. The amount of liability on the Company’s books for revenue not recognized as of June 30, 2019 and December 31, 2018 were $285,298 and $409,334, respectively. Shipping and Handling Costs The Company's shipping and handling costs are included in cost of goods sold for all periods presented. Foreign Currency We operate primarily in the United States. Foreign sales of products and services are primarily denominated in U.S. dollars. We also conduct limited business outside the United States through our foreign subsidiary in Germany, where business is largely transacted in non-U.S. dollar currencies, particularly the Euro, which is subject to fluctuations due to changes in foreign currency exchange rates. Accordingly, we are subject to exposure from changes in the exchange rates of local currencies. Foreign currency transaction gains and losses are recorded in other income (expense), net in the consolidated statements of operations OSS GmbH operates as an extension of OSS’s domestic operations. The functional currency of OSS GmbH is the Euro. Transactions denominated in currencies other than the functional currency are remeasured to the functional currency at the average exchange rate in effect during the period. At the end of each reporting period, monetary assets and liabilities are remeasured using exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities are remeasured at historical exchange rates. Consequently, changes in the exchange rates of the currencies may impact the translation of the foreign subsidiaries’ statements of operations into U.S. dollars, which may in turn affect our consolidated statements of operations. Derivative Financial Instruments We employ derivatives to manage certain market risks through the use of foreign exchange forward contracts. We do not use derivatives for trading or speculative purposes. Our derivatives are designated as a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). We hedge a portion of the exchange risk involved in anticipation of highly probable foreign currency-denominated transactions. In anticipation of these transactions, we enter into foreign exchange contracts to provide currency at a fixed rate. As of June 30, 2019, the Company had no foreign exchange contracts outstanding. Unrealized gains on derivatives designated as cash flow hedges are recorded at fair value as assets, and unrealized losses on derivatives designated as cash flow hedges are recorded at fair value as liabilities. For derivative instruments designated as cash flow hedges, the effective portion is reported as a component of accumulated other comprehensive income until reclassified into interest expense in the same period the hedged transaction affects earnings. The gain or loss on the ineffective portion is recognized as “Other income (expense) – net” in the consolidated statements of income in each period. Stock-Based Compensation The Company accounts for employee and director share-based compensation in accordance with the provisions of ASC Topic 718 “Compensation – Stock Compensation” All transactions in which goods or services are the consideration received for the issuance of equity instruments to non-employees are accounted for based on the fair value of the consideration received or the fair value of the equity instrument issued, whichever is more reliably measurable. The measurement date used to determine the estimated fair value of the equity instrument issued is the earlier of the date on which the third-party performance is complete or the date on which it is probable that performance will occur. Employee and director stock-based compensation expense recognized during the period is based on the value of the portion of stock-based payment awards that is ultimately expected to vest during the period. Given that stock-based compensation expense recognized in the accompanying consolidated statements of operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. The Company’s estimated average forfeiture rates are based on historical forfeiture experience and estimated future forfeitures. Compensation cost for stock awards, which include restricted stock units (“RSUs”), is measured at the fair value on the grant date and recognized as expense, net of estimated forfeitures, over the related service period. The fair value of stock awards is based on the quoted price of our common stock on the grant date. The estimated fair value of common stock option awards is calculated using the Black-Scholes option pricing model. The Black-Scholes model requires subjective assumptions regarding future stock price volatility and expected time to exercise, along with assumptions about the risk-free interest rate and expected dividends, all of which affect the estimated fair values of the Company’s common stock option awards. The expected term of options granted is calculated using the simplified method, which is the weighted average vesting period and the contractual lives of the options. This calculation is based on a method acceptable in instances where the vesting and exercise terms of options granted meet certain conditions and where limited historical exercise data is available. The expected volatility is based on the historical volatility of the common stock of comparable public companies that operate in similar industries as the Company. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the expected term of the grant effective as of the date of the grant. The expected dividend assumption is based on the Company’s history and management’s expectation regarding dividend payouts. Compensation expense for common stock option awards with graded vesting schedules is recognized on a straight-line basis over the requisite service period for the last separately vesting portion of the award, provided that the accumulated cost recognized as of any date at least equals the value of the vested portion of the award. If there are any modifications or cancellations of the underlying vested or unvested stock-based awards, the Company may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense, or record additional expense for vested stock-based awards. Future stock-based compensation expense and unearned stock- based compensation may increase to the extent that the Company grants additional common stock options or other stock-based awards. Business Combinations We utilize the acquisition method of accounting for business combinations and allocate the purchase price of an acquisition to the various tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. We primarily establish fair value using the income approach based upon a discounted cash flow model. The income approach requires the use of many assumptions and estimates including future revenues and expenses, as well as discount factors and income tax rates. Other estimates include: • Estimated step-ups or write-downs for fixed assets and inventory; • Estimated fair values of intangible assets; and • Estimated income tax assets and liabilities assumed from the target While we use our best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the business acquisition date, our estimates and assumptions are inherently uncertain and subject to refinement. As a result, during the purchase price allocation period, which is generally one year from the business acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. For changes in the valuation of intangible assets between preliminary and final purchase price allocation, the related amortization is adjusted in the period it occurs. Subsequent to the purchase price allocation period any adjustment to assets acquired or liabilities assumed is included in operating results in the period in which the adjustment is determined. Should we issue shares of our common stock in an acquisition, we will be required to estimate the fair value of the shares issued. See Note 3. Advertising Costs Advertising costs are expensed as incurred and included in marketing and selling expense in the accompanying consolidated statements of operations. Advertising costs for the three month periods ended June 30, 2019 and 2018 were $13,006 and $26,754, respectively, and $22,006 and $44,380 for the six month periods ended June 30, 2019 and 2018. Research and Development Expenses Research and development expenditures are expensed in the period incurred. Research and development expenses primarily consist of salaries, benefits and stock-based compensation, as well as consulting expenses and allocated facilities and other overhead costs. Research and development activities include the development of new technologies, features and functionality in support of the Company’s products and customer needs. Income Taxes The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the consolidated financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. Under ASC Topic 740, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Additionally, ASC Topic 740 provides requirements for derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company’s policy is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company files income tax returns in the U.S. federal jurisdiction, California and Germany. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act reduces the corporate tax rate to 21%, effective January 1, 2018. The Company does not foresee material changes to its gross liability of uncertain tax positions within the next twelve months. Interest Expense Interest expense consists primarily of interest associated with the Company’s issued debt including the amortization of debt discounts. The Company recognizes the amortization of debt discounts and the amortization of interest costs using a straight-line method which approximates the effective interest method. Net (Loss) Income Per Share Basic net (loss) income per share is calculated by dividing net (loss) income by the weighted-average common shares outstanding during the period. Diluted net (loss) income per share is calculated by dividing the net (loss) income by the weighted-average shares and dilutive potential common shares outstanding during the period. Dilutive potential shares consist of dilutive shares issuable and the exercise or vesting of outstanding stock options and warrants, respectively, computed using the treasury stock method. During a period where a net loss is incurred, dilutive potential shares are excluded from the computation of dilutive net loss per share, as inclusion is anti-dilutive. On February 1, 2018, in connection with the Company’s initial public offering, the Company’s outstanding Series A, Series B, and Series C, Preferred Stock was automatically converted to common stock, par value $0.0001.
