On an ongoing basis, management evaluates its estimates, including those related to preclinical and clinical study trial accruals, fair value of assets and liabilities, the fair value of right-of-use assets (“ROU Assets”) and lease liabilities, fair value of pre-funded warrants, revenue recognition, and the fair value of stock-based compensation awards. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that management believes to be reasonable under the circumstances. Actual results could differ from those estimates.</p>

The Company has not experienced any credit losses in such accounts and does not believe it is exposed to any significant credit risk on these funds.</p> <p style="margin-top:12pt;margin-bottom:0pt;text-indent:5.73%;color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company’s investment policy limits investments to certain types of securities issued by the U.S. government, its agencies, and institutions with investment-grade credit ratings and places restrictions on maturities and concentration by type and issuer. The Company is exposed to credit risk in the event of a default by the financial institutions holding its cash, cash equivalents, and marketable securities and issuers of marketable securities to the extent recorded on the consolidated balance sheets. Through December 31, 2020, the Company has no off-balance sheet concentrations of credit risk.</p>

The standard eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the standard modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. The amendments in ASU 2020-06 are effective for the Company as defined by the SEC for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but not earlier than fiscal years beginning after December 15, 2020. The Company is currently evaluating the impact of ASU 2020-06 on its consolidated financial statements and related disclosures.</p> <p style="margin-bottom:0pt;margin-top:0pt;text-indent:5.73%;font-family:Times New Roman;font-size:10pt;"> </p> <p id="keyword" style="margin-bottom:0pt;margin-top:0pt;text-indent:5.73%;color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"><span style="Background-color:#FFFFFF;">In October 2020, the FASB issued ASU 2020-10, </span><span style="font-style:italic;Background-color:#FFFFFF;">Codification Improvements</span><span style="Background-color:#FFFFFF;">. The standard contains improvements to the Codification by ensuring that all guidance that requires or provides an option for an entity to provide information in the notes to financial statements is codified in the disclosure section of the Codification. The standard also improves various topics in the Codification so that entities can apply guidance more consistently on codifications that are varied in nature where the original guidance may have been unclear. The amendments in ASU 2020-10 are effective for the Company for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. The Company does not expect the adoption of ASU 2020-10 to have a material impact on its consolidated financial statements and related disclosures.</span></p>
