Fair Value Measurements	*Fair value measurements*: “Fair value“ is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. There are three levels of fair value estimation, based on the observability of inputs: Level 1. Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Valuation adjustments and block discounts are not applied to Level 1 instruments. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Level 2. Valuations based on one or more quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. Level 3. Valuations based on inputs that are unobservable and significant to the overall fair value measurement. As of September 30, 2023 and 2022, the Company believes the amounts reported for the carrying value of cash, other current assets, accounts payable, accrued expenses (related parties), and other accrued expenses, as reflected in the consolidated balance sheets, approximate fair value, due to the short maturity of these instruments.
