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.
The Company considers cash of 23,000 Euro ($25,801) that is pledged as collateral against certain revolving debt obligations related to its European rental fleet operations to be restricted cash.
Deferred compensation plan assets represent investments in securities (primarily mutual funds) traded in an active market held for the benefit of certain employees of the Company as part of a deferred compensation plan. Deferred compensation plan asset balances are recorded as a component of Other long-term assets in the Condensed Consolidated Balance Sheets. An equal and offsetting liability is also recorded in regards to the deferred compensation plan as a component of Other long-term liabilities in the Condensed Consolidated Balance Sheets. Changes in the fair value of the plan assets and the related liability are reflected in Other income (expense), net and Selling, general and administrative expenses, respectively, in the Condensed Consolidated Statements of Income and Comprehensive Income.
Foreign currency forward exchange contracts outstanding at April 30, 2019 are used to exchange Pounds Sterling (GBP) for Euro. The total notional value of these contracts at April 30, 2019 is 25,000 GBP, and these contracts have various maturity dates through August 2019.
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, 2019, the outstanding swaps had notional contract values of $900,000, partially hedging the interest rate risk related to the Company’s U.S. dollar term loan tranche that matures in February 2026.
The fair value of forward currency 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 calculated by discounting the estimated future cash flows based on the applicable observable yield curves.
