Total Warrant Liabilities
$92,946 $203,726 
The Pre-funded Warrants and 2025 ADS Warrants are accounted for as liabilities in accordance with ASC 815-40, Derivatives and Hedging, Contracts in Entity’s Own Equity (“ASC 815-40”), as both warrants contain contingent exercise provisions that do not meet the requirements of the indexation guidance under ASC 815-40 and could require the Company to pay cash to settle the warrants. The warrants are presented within warrant liabilities in the accompanying consolidated balance sheets. The warrant liabilities were measured at fair value at inception and on a recurring basis, with changes in fair value presented within the consolidated statements of operations and comprehensive loss.
The Pre-funded Warrants are considered to be Level 2 in the fair value hierarchy as the inputs used to determine fair market value are observable against the Company’s stock price. The 2025 ADS Warrant are considered to be Level 3 in the fair value hierarchy as they have been recorded at fair value using the Black-Scholes model, using unobservable assumptions that have been probability-weighted for specified data milestones. As of December 31, 2025, the assumptions are as follows:
