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 and disclosure of contingent assets and liabilities at the date of the financial statements, and reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions used in these condensed consolidated financial statements primarily include those related to revenue recognition, inventory valuation, valuation of share-based awards, contingencies and income tax valuation allowances. Actual results could differ from these estimates and assumptions, and any such differences may be material to the Company’s condensed consolidated financial statements.

The COVID-19 pandemic did not materially and adversely impact the Company's overall operating results or business operations during the three and nine months ended September 30, 2021. As of the date of issuance of these condensed consolidated financial statements, the Company is not aware of any specific event or circumstance related to the COVID-19 pandemic that would require management to update the significant estimates and assumptions used in the preparation of the condensed consolidated financial statements, as compared to those disclosed in the Annual Report on Form 10-K for the year ended December 31, 2020. As new events continue to evolve and additional information becomes available, any changes to these estimates and assumptions will be recognized in the condensed consolidated financial statements as soon as they become known.

In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which eliminates certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The standard also clarifies and simplifies other aspects of the accounting for income taxes. The standard became effective for annual reporting periods beginning after December 15, 2020. The standard is generally applied prospectively, with certain exceptions. The Company adopted the standard in the first quarter of 2021 and the adoption did not have a material impact on its condensed consolidated financial statements.
