During the years ended December 31, 2021 and 2020, we had no cash flow hedges outstanding. During 2019, we had nine interest rate swaps outstanding, all of which expired on April 15, 2019, whereby we paid a fixed rate on a total notional amount of $1.0 billion and received one-month LIBOR. The average fixed rate payable on these swaps was 1.31%.

When applicable, we measure our interest rate swaps at fair value on a recurring basis. The fair value of our interest rate swaps is based on quotes from our counterparties. We consider those inputs to be “level 2” in the fair value hierarchy as outlined in the authoritative guidance for disclosures in connection with derivative instruments and hedging activities.

We use forward exchange contracts to hedge our net investment in foreign operations against movements in exchange rates. The effective portion of the unrealized gains or losses on these contracts is recorded in foreign currency translation adjustment within accumulated other comprehensive income and remains there until either the sale or liquidation of the subsidiary. In connection with these forward exchange contracts, we recorded net cash inflows of approximately $1 million during 2021, net cash outflows of approximately $22 million during 2020 and net cash inflows of approximately $20 million during 2019.

The following table presents the effects of our interest rate swap agreements and our foreign currency foreign exchange contracts on our results of operations for the three years ended December 31 (in thousands):

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The following fair value hierarchy classifies the inputs to valuation techniques used to measure fair value into one of three levels:

The following tables present the assets and liabilities recorded at fair value on a recurring basis:

The fair value of our money market mutual funds, certificates of deposit and equity securities with a readily determinable fair value are computed based upon quoted market prices in an active market. The fair value of deferred compensation assets and the offsetting liability are computed based on market prices in an active market held in a rabbi trust. The fair value of our interest rate swaps are based on quotes from our counter parties. The fair value of our foreign currency exchange contracts is valued using quoted forward exchange rates and spot rates at the reporting date

As of December 31, 2020, in addition to the $577 million reflected above in cash and cash equivalents, we have approximately $581 million of other cash accounts that earn interest at variable rates ranging from .20% to .25%.
