FAIR VALUE MEASUREMENTS

9 Months Ended

Dec. 31, 2022

The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant non-observable inputs. The following tables present the Company's financial assets and liabilities measured on a recurring basis using the fair value hierarchy at December 31, 2022 and March 31, 2022 (in thousands):

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company measures certain financial assets and liabilities at fair value, including marketable securities and derivative financial instruments.

The Company's Level 1 investments are classified as such because they are valued using quoted market prices or alternative pricing sources with reasonable levels of price transparency.

The Company's Level 2 investments are classified as such because they are valued using observable inputs other than Level 1 quoted prices that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets in markets that are not active.
