7. | MARKETABLE DEBT SECURITIES
Marketable debt securities consist of U.S. Treasury Securities and Corporate Bonds. Management determines the appropriate classification of these securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date. The Company classifies its investments as available-for-sale pursuant to ASC 320, Investments—Debt Securities. Investments are recorded at fair value, with unrealized gains and losses included as a component of accumulated other comprehensive income in stockholders’ equity and a component of total comprehensive income in the consolidated statements of operations and comprehensive income, until realized. Realized gains and losses are included in investment income on a specific-identification basis. The Company estimates expected credit losses for investments when unrealized losses exist. Unrealized losses that are credit related are recognized in net income and unrealized losses that are not credit related are recognized in accumulated other comprehensive income. For the three and six months ended May 31, 2025, there were realized gains on investments of $0.1 million. For the three and six months ended May 31, 2025, there were net unrealized gains on marketable debt securities of $0.1 million.

Fair Value Measurement The Company follows a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to settle a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows: ● Level 1- Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. ● Level 2- Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. ● Level 3- Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. The following table summarizes the fair value of marketable debt securities by level within the fair value hierarchy as of May 31, 2025:
