Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company’s estimates include revenue recognition, stock-based compensation expense, bonus and warranty accrual, income tax valuation allowances and reserves, recovery of long‑lived assets, lease liability, inventory valuation, accounts receivable, allowance for doubtful accounts and available-for-sale securities. Actual results could materially differ from those estimates, especially in light of the significant uncertainty that remains as to the full impact of COVID-19 on the Company’s operations, as well as those of its workforce, supply chains, distribution networks and those of its customers.

Significant Accounting Policies

There have been no material changes in the Company’s significant accounting policies from those previously disclosed in the consolidated financial statements included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 29, 2022.

Fair Value of Financial Instruments

The carrying value of financial instruments classified as current assets and current liabilities approximate fair value due to their liquidity and short-term nature. Investments that are classified as available-for-sale are recorded at fair value, which is determined using quoted market prices, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. The carrying value of the SVB Term Loan (see Note 8) is estimated to approximate its fair value as the interest rate approximates the market rate for debt with similar terms and risk characteristics.

The Company’s obligation related to an asset purchase transaction with a then-common stockholder of the Company, (the “NuvoGen obligation”) had an estimated fair value of approximately $3.9 million as of June 30, 2022. This estimated fair value represents a Level 3 measurement that has been determined using a Monte Carlo simulation with key assumptions including future revenue, volatility, discount and risk-free rates.

Inventory

Inventory is stated at the lower of cost or net realizable value. The Company determines the cost of inventory using the first-in, first out method. The Company estimates the recoverability of inventory by reference to internal estimates of future demands and product life cycles, including expiration. The Company periodically analyzes its inventory levels to identify inventory that may expire prior to expected sale or has a cost basis in excess of its estimated realizable value and records a charge to expense for such inventory as appropriate.

We charge cost of sales for inventory provisions to write-down our inventory to the lower of cost or net realizable value or for obsolete or excess inventory. Most of our inventory provisions relate to excess quantities of products, based on our inventory levels and future product purchase commitments compared to assumptions about future demand and market conditions. Once inventory has been written-off or written-down, it creates a new cost basis for the inventory that is not subsequently written-up.

New Accounting Pronouncements

The following are new Financial Accounting Standards Board ("FASB") Accounting Standard Updates ("ASU") that had not been adopted by the Company as of June 30, 2022:

In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions ("ASU 2022-03"), which amends Accounting Standards Codification ("ASC") 820 to clarify that a contractual sales restriction is not considered in measuring an equity security at fair value and to introduce new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value. ASU 2022-03 applies to both holders and issuers of equity and equity-linked securities measured at fair value. The amendments in this ASU are effective for the Company in fiscal years and interim periods within those fiscal years, beginning after December 15, 2023. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The Company is still evaluating the impact of this pronouncement on the financial statements.

In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and also simplifies the diluted earnings per share calculation in certain areas. The standard became effective for public business entities, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years and interim periods within those fiscal years, beginning after December 15, 2021. For all other entities, the standard will be effective for fiscal years beginning after December 15, 2023. Early adoption is permitted, and adoption must be as of the beginning of the Company’s annual fiscal year. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses, which was subsequently amended by ASU 2018-19, ASU 2019-10 and ASU 2020-02, and requires the measurement of expected credit losses for financial instruments carried at amortized cost held at the reporting date based on historical experience, current conditions and reasonable forecasts. The updated guidance also amends the current other-than-temporary impairment model for available-for-sale debt securities by requiring the recognition of impairments relating to credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized cost basis and its fair value. In addition, the length of time a security has been in an unrealized loss position will no longer impact the determination of whether a credit loss exists. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. With the issuance of ASU 2019-10 in November 2019, the standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2022. The Company will continue to assess the possible impact of this standard, but currently does not expect the adoption of this standard will have a significant impact on its consolidated financial statements, given the high credit quality of the obligors to its available-for-sale debt securities and its history of minimal bad debt expense relating to trade accounts receivable.
