4. | Derivative Financial Instruments
We periodically utilize derivative instruments for hedging and non-trading purposes to manage exposure to changes in interest rates and to maintain an appropriate mix of fixed and variable-rate debt. At inception of a derivative contract, we document relationships between derivative instruments and hedged items, as well as our risk-management objective and strategy for undertaking various derivative transactions, and assess hedge effectiveness. If it is determined that a derivative is not highly effective as a hedge, or if a derivative ceases to be a highly effective hedge, we discontinue hedge accounting prospectively. We entered into a receive fixed-rate and pay variable-rate interest rate swap agreement simultaneously with the issuance of our $350 million of 3.30% senior notes due August 2022, to effectively convert this fixed-rate debt to variable-rate. The notional amount of this interest rate swap agreement equals that of the corresponding fixed-rate debt. The applicable interest rate under this agreement is based on LIBOR plus an established margin, resulting in an interest rate of 1.51% for our $350 million of 3.30% senior notes at December 31, 2021. The swap expires when the corresponding senior notes are due. The fair value of this swap is recorded in current assets in our Consolidated Balance Sheet at December 31, 2021. See Note 9, Fair Value Measurements, for disclosure of fair value. This derivative meets the required criteria to be designated as a fair value hedge, and as the specific terms and notional amount of this derivative instrument match those of the fixed-rate debt being hedged, this derivative instrument is assumed to perfectly hedge the related debt against changes in fair value due to changes in the benchmark interest rate. Accordingly, any change in the fair value of this interest rate swap recorded in earnings is offset by a corresponding change in the fair value of the related debt.
