On an ongoing basis, we evaluate our estimates, including those related to the valuation of share-based awards, the discount rate used in estimating the present value of the right-of-use assets and lease liabilities, clinical trial accruals and the assessment of our ability to fund our operations for at least the next 12 months from the date of issuance of these condensed consolidated financial statements. We base our estimates on historical experience and other market-specific </span><span style="color:#000000;white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;min-width:fit-content;">or other relevant assumptions that we believe to be reasonable under the circumstances. Estimates are assessed each reporting period and updated to reflect current information. As future events and their effects cannot be determined with precision, actual results may materially differ from those estimates or assumptions.</span>

Our investment portfolio is maintained in accordance with our investment policy, which is designed to preserve capital, safeguard funds and limit exposure to risk. While we maintain cash deposits in Federal Deposit Insurance Corporation insured financial institutions in excess of federally insured limits, we do not believe that we are exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.
