 assumptions using industry experience and other factors; however, actual results could differ materially from these estimates and could have an adverse effect on our consolidated financial statements. While our significant accounting policies are more fully described in the notes to our consolidated financial statements, we believe that the accounting policies discussed below are most critical to understanding and evaluating our historical and future performance.

Research and Development Expenses

All research and development costs are expensed as incurred. Research and development costs consist primarily of salaries, employee benefits, costs associated with preclinical studies and clinical trials (including amounts paid to clinical research organizations and other professional services). Payments made prior to the receipt of goods or services to be used in research and development are capitalized until the goods or services are received.

We record accruals for estimated research and development costs, comprising payments for work performed by third party contractors, laboratories, participating clinical trial sites, and others. Some of these contractors bill monthly based on actual services performed, while others bill periodically based upon achieving certain contractual milestones. For the latter, we accrue the expenses as goods or services are used or rendered. Clinical trial site costs related to patient enrollment are accrued as patients enter and progress through the trial. Upfront costs, such as costs associated with setting up clinical trial sites for participation in the trials, are expensed immediately once incurred as research and development expenses.

Stock-based Compensation

We recognize the compensation expense related to stock options, third-party warrants, and restricted stock unit (“RSU”) awards granted, based on the estimated fair value of the awards on the date of grant. The fair value of employee stock options and third-party warrants are generally determined using the Black-Scholes option-pricing model using various inputs, including estimates of historic volatility, term, risk-free rate, and future dividends. The grant date fair value of the stock-based awards, which have graded vesting, is recognized using the straight-line method over the requisite service period of each stock-based award, which is generally the vesting period of the respective stock-based awards. The Company recognizes forfeitures as they occur.

As of December 31, 2024, there were 3 Rollover RSU awards vested and unissued and 64 stock options outstanding.

Recent Accounting Pronouncements

See Note 2 to our consolidated financial statements for more information about recent accounting pronouncements, the timing of their adoption, and our assessment, to the extent we have made one yet, of their potential impact on our financial condition of results of operations.
