FAIR VALUE MEASUREMENT
4. FAIR VALUE MEASUREMENT

The Company uses a three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:
•Level 1: Valuation is based on quoted prices (unadjusted) in active markets for identical assets or liabilities.
•Level 2: Valuation is based on observable market-based inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
•Level 3: Valuation is based on significant unobservable inputs which are supported by little or no market activity.
The following tables represent the fair value hierarchy of the Company’s investments as of June 30, 2026 and September 30, 2025, respectively (amounts in thousands):
