Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. In management’s opinion, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly the Company’s financial position, results of operations, and cash flows. The financial data and other information disclosed in these notes related to the three months ended March 31, 2022 and 2021 are also unaudited. The unaudited condensed results of operations are not necessarily indicative of the operating results that may occur for the full fiscal year ending December 31, 2022. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to instructions, rules, and regulations prescribed by the United States Securities and Exchange Commission, or the SEC. Management believes that the disclosures provided here are adequate to make the information presented not misleading when these unaudited condensed consolidated financial statements are read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K. Significant Accounting Policies The Company’s significant accounting policies are disclosed in the audited consolidated financial statements for the year ended December 31, 2021, in the Company's Annual Report on Form 10-K filed with the SEC on March 23, 2022, there have been no changes to the Company's significant accounting policies except as noted below. Marketable Securities All marketable securities have original maturities greater than 90 days. The Company has classified its investments with maturities beyond one year as short-term, based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. The Company considers its investment portfolio of marketable securities to be available-for-sale. Accordingly, these investments are recorded at fair value. Unrealized gains and losses are reported as the accumulated other comprehensive items in stockholders’ equity. Amortization and accretion of premiums and discounts are recorded in other income (expense) within the consolidated statements of operations and comprehensive loss. Realized gains or losses are included in interest income or interest expense, respectively. If any adjustment to fair value reflects a decline in value of the investment, the Company considers all available evidence such as industry, financial inputs, and capital markets data to evaluate the extent to which the decline is other than temporary and, if so, marks the investment to market on the Company’s condensed consolidated statement of operations and comprehensive loss. Recently Adopted Accounting Pronouncements The Company assessed the recent accounting pronouncements for the three months ended March 31, 2022 and determined no pronouncements have material impact to the condensed consolidated financial statements.
