Other than policies noted below, there have been no significant changes to the significant accounting policies disclosed in Note 2, Summary of Significant Accounting Policies, of the annual audited financial statements included in the Annual Report.

The preparation of condensed financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed financial statements and accompanying notes to the condensed financial statements. The accounting estimates that require management’s most significant, difficult and subjective judgments include, but are not limited to, revenue recognition and allowance for expected credit losses, the valuation of notes receivable and inventory, the assessment of recoverability of intangible assets and their estimated useful lives, the valuation and recognition of stock-based compensation, operating lease right-of-use assets and liabilities, and the recognition and measurement of current and deferred income tax assets and liabilities. Management evaluates its estimates on an ongoing basis as there are changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from these estimates.

The COVID-19 pandemic continues to directly and indirectly impact the Company’s business, results of operations and financial condition, including revenue, expenses, reserves and allowances. The Company continues to monitor developments that are highly uncertain, including supply chain disruptions and price increases, as well as the economic impact on domestic and international suppliers, customers, and markets. The Company assessed certain accounting matters that require consideration of forecasted financial information, including, but not limited to, its current expected credit losses, the carrying value of the Company's intangible assets and other long-lived assets, and valuation allowances in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 as of June 30, 2022 and through the date of this report. As a result of these assessments, there were no impairments or material increases in expected credit losses or valuation allowances that impacted the Company's condensed financial statements as of and for the three and six months ended June 30, 2022 and 2021. However, the Company's future assessment of the magnitude and duration of COVID-19, as well as other factors, could result in material impacts to the condensed financial statements in future reporting periods.

As of the date of issuance of these unaudited condensed interim financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update estimates, judgments or revise the carrying value of any assets or liabilities.

The fair value of the Company’s financial instruments are estimates of the amounts that would be received if the Company were to sell an asset or the Company paid to transfer a liability in an orderly transaction between market participants at the measurement date or exit price. The assets and liabilities are categorized and disclosed in one of the following three categories:

•

Level 1—based on quoted market prices in active markets for identical assets and liabilities.

•

Level 2—based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•

Level 3—based on unobservable inputs using management’s best estimate and assumptions when inputs are unavailable.

Fair value measurements are classified in their entirety based on the lowest level of input that is significant to their fair value measurement.

The carrying value of the Company’s cash, cash equivalents, accounts receivable, accounts payable, accrued liabilities, and other current liabilities approximate fair value based on the short-term maturities of these instruments. The carrying value of the Company’s notes receivable also approximates fair value based on the associated credit risk.

Income tax expense/(benefit) from continuing operations for the three and six months ended June 30, 2022 and 2021 was $0 in each period, which resulted primarily from maintaining a full valuation allowance against the Company’s deferred tax assets.

The Company reviewed recent pronouncements issued by the FASB and other authoritative standards groups with future effective dates and concluded the pronouncements are either not applicable to the Company or are not expected to have a material impact on the Company’s financial position or results of operations.
