NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of these unaudited consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect amounts reported in the consolidated financial statements and the accompanying notes. Significant estimates in these unaudited consolidated financial statements include allowances on accounts receivable, inventory, and deferred taxes, as well as estimates for accrued warranty expenses, goodwill and the ability of goodwill to be realized, revenue deferrals, effects of stock-based compensation and warrants, contingent liabilities, and the provision or benefit for income taxes. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ materially from those estimates.

Critical Accounting Policies

Information with respect to the Company’s critical accounting policies, which management believes could have the most significant effect on the Company’s reported results and require subjective or complex judgments by management is contained in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the 2018 Form 10-K. Management believes that there have been no significant changes during the six months ended June 30, 2019 in the Company’s critical accounting policies from those disclosed in Item 7 of the 2018 Form 10-K.

Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market (or, if none exists, the most advantageous market) for the specific asset or liability at the measurement date (referred to as the “exit price”). The fair value is based on assumptions that market participants would use, including a consideration of non-performance risk. Under the accounting guidance for fair value hierarchy, there are three levels of measurement inputs. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable, either directly or indirectly. Level 3 inputs are unobservable due to little or no corroborating market data.

The Company’s financial instruments, consisting of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities, and the SWK Loan as discussed in Note 9, approximate fair value because of the liquid or short-term nature of these items.

Concentration of Credit Risk, Interest Rate Risk and Foreign Currency Exchange Rate

Financial instruments which potentially expose the Company to a concentration of credit risk consist principally of cash and cash equivalents, restricted cash, and trade accounts receivable. The Company maintains its cash and cash equivalents and restricted cash with established commercial banks. At times, balances may exceed federally insured limits. To minimize the risk associated with trade accounts receivable, management performs ongoing credit evaluations of customers’ financial condition and maintains relationships with the Company’s customers that allow management to monitor current changes in business operations so the Company can respond as needed. The Company does not, generally, require customers to provide collateral before it sells them its products. However, the Company has required certain distributors to make prepayments for significant purchases of products.

Substantially all of the Company’s revenue is denominated in U.S. dollars, including sales to international distributors. Only a small portion of its revenue and expenses is denominated in foreign currencies, principally the Euro and Indian Rupee. The Company’s foreign currency expenditures primarily consist of the cost of maintaining offices, consulting services, and employee-related costs. During the six-month periods ended June 30, 2019 and 2018, the Company did not enter into any hedging contracts. Future fluctuations in the value of the U.S. dollar may affect the price competitiveness of the Company’s products outside the U.S.

Recent Accounting Pronouncements

Changes to GAAP are established by the Financial Accounting Standards Board (the “FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification.

The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s consolidated financial position and results of operations.

Adopted Accounting Pronouncements

In February 2016, the FASB established ASU Topic 842 – Leases, by issuing ASU Topic No. 2016-02 (“Topic 842”), which requires lessees to recognize lease on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU Topic 2018-11 – Targeted Improvements. The new standard establishes a right-of-use model (“ROU”) that requires a lessee to recognize a ROU asset and a lease liability for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the statement of operations.

The Company adopted Topic 842 in the first quarter of 2019 utilizing the modified retrospective transition method and a cumulative effect adjustment at the beginning of the first quarter of 2019. The Company has elected the package of practical expedients, which allows the Company not to reassess (1) whether any expired or existing contracts as of the adoption date are or contain a lease, (2) lease classification for any expired or existing leases as of the adoption date, and (3) initial direct costs for any existing leases as of the adoption date. The Company did not elect to apply the hindsight practical expedient when determining lease term and assessing impairment of the right-to-use assets. The adoption of Topic 842 resulted in the recognition of right-of use assets of approximately $0.8 million after a $0.2 million adjustment for deferred rent, and lease liabilities for operating leases of approximately $1.0 million, and no cumulative effect adjustment on retained earnings on its unaudited Consolidated Balance Sheets nor material impact to its unaudited Consolidated Statements of Operations and Comprehensive Loss in the period of adoption. Right-of-use assets are included in Other assets, and lease liabilities are included in Accrued liabilities or Other liabilities in the unaudited consolidated balance sheet for the period ended June 30, 2019. See Note 10 for additional information.

Recently Issued Accounting Standards

In June 2016, the FASB issued a new standard to replace the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company will be required to use a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. The standard will be effective for the Company beginning January 1, 2020, with early adoption permitted beginning January 1, 2019. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements, including accounting policies, processes, and systems.
