Fair Value Measurements Fair Value Measurements
The financial assets and liabilities that are accounted for at fair value on a recurring basis at April 30, 2021 and July 31, 2020 are as follows:
Input LevelApril 30, 2021July 31, 2020
Cash equivalentsLevel 1$211$227,154
Deferred compensation plan mutual fund assetsLevel 1$46,931$47,327
Deferred compensation plan liabilitiesLevel 1$77,289$61,290
Foreign currency forward contract assetLevel 2$494$
Interest rate swap liabilitiesLevel 2$15,782$26,664

Cash equivalents represent investments in government and other money market funds traded in an active market and are reported as a component of Cash and cash equivalents in the Condensed Consolidated Balance Sheets.

Deferred compensation plan assets accounted for at fair value are investments in securities traded in an active market held for the benefit of certain employees of the Company as part of a deferred compensation plan. Additional plan investments in corporate-owned life insurance are recorded at their cash surrender value, not fair value, and therefore are not included above.

Foreign currency forward contracts outstanding at April 30, 2021 are used to exchange British Pounds Sterling ("GBP") for Euro. The total notional value of these contracts, including designated hedges and other contracts not designated, at April 30, 2021 is 54,000 GBP ($75,110), and these contracts have various maturity dates through January 31, 2022.

The Company entered into interest rate swaps to convert a portion of the Company's long-term debt from floating rate to fixed rate debt. As of April 30, 2021, the outstanding swaps had notional contract values of $532,025, partially hedging the interest rate risk related to the Company's U.S. dollar term loan tranche that matures in February 2026. The Company's other interest rate swaps not designated as hedging instruments had a notional contract value of $33,634 at April 30, 2021.
The fair value of foreign currency forward contracts is estimated by discounting the difference between the contractual forward price and the current available forward price for the residual maturity of the contract using observable market rates. The fair value of interest rate swaps is determined by discounting the estimated future cash flows based on the applicable observable yield curves.
