We have entered into interest rate derivatives to hedge the current and future interest rate payments on our variable rate debt. These derivative financial instruments can include interest rate swaps, caps, floors, options and forward contracts.

As of December 31, 2021, we had interest rate caps and swaps outstanding, with underlying variable benchmark interest rates ranging from one to six-month U.S. dollar LIBOR.

Some of our agreements with derivative counterparties require a two-way cash collateralization of derivative fair values. We had not advanced any cash collateral to, or received any cash collateral from, counterparties as of December 31, 2021 or 2020.

The counterparties to our interest rate derivatives are primarily major international financial institutions. We continually monitor our positions and the credit ratings of the counterparties involved and limit the amount of credit exposure to any one party. We could be exposed to potential losses due to the credit risk of non-performance by these counterparties. We have not experienced any losses to date.

Our derivative assets are recorded in other assets and our derivative liabilities are recorded in accounts payable, accrued expenses and other liabilities in our Consolidated Balance Sheets.

The following tables present notional amounts and fair values of derivatives outstanding as of December 31, 2021 and 2020:
