Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivative Instruments and Hedging Activities Disclosure [Text Block] | 10. Derivative Financial Instruments and Hedging Activities Risk Management Objective of Using Derivatives. We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of our debt funding and the use of derivative financial instruments. Specifically, we may enter into derivative financial instruments to manage exposures arising from business activities resulting in differences in the amount, timing, and duration of our known or expected cash payments principally related to our borrowings. See Note 2, "Summary of Significant Accounting Policies and Recent Accounting Pronouncements" for a further discussion of derivative financial instruments. Cash Flow Hedges of Interest Rate Risk. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish these objectives, we primarily use interest rate swaps and caps as part of our interest rate risk management strategy. Interest rate swaps involve the receipt of variable rate amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Designated Hedges. The gain or loss on the derivatives designated and qualifying as cash flow hedges is reported as a component of other comprehensive income or loss and subsequently reclassified into earnings in the period the hedged forecasted transaction affects earnings and presented in the same line item as the earnings effect of the hedged item. At December 31, 2021, 2020 and 2019, we had no designated hedges outstanding. The table below presents the effect of our derivative financial instruments which were settled in prior years in the consolidated statements of income and comprehensive income for the years ended December 31, 2021, 2020, and 2019:
