Senior Unsecured Notes On February 26, 2021, we issued $1.1 billion in aggregate principal amount of 1.200% senior unsecured notes due March 2026. We incurred debt issuance costs of approximately $8.6 million, including underwriting fees, fees for professional services and registration fees, which were capitalized and reflected as a reduction of the related carrying amount of the notes in our consolidated balance sheet at March 31, 2021. Interest on the notes is payable semi-annually in arrears on March 1 and September 1 of each year, commencing September 1, 2021. The notes are unsecured and unsubordinated indebtedness and rank equally in right of payment with all of our other outstanding unsecured and unsubordinated indebtedness. We used the net proceeds from this offering to fund the redemption in full of the 3.800% senior unsecured notes due April 2021, to repay a portion of the outstanding indebtedness under our revolving credit facility and for general corporate purposes. As of March 31, 2021, our senior notes had a total carrying amount of $7.5 billion and an estimated fair value of $7.8 billion. The estimated fair value of our senior notes was based on quoted market prices in an active market and is considered to be a Level 1 measurement of the valuation hierarchy. The fair value of other long-term debt approximated its carrying amount at March 31, 2021. Compliance with Covenants The senior unsecured term loan and revolving credit facility contain customary conditions to funding, affirmative covenants, negative covenants, financial covenants and events of default. As of March 31, 2021, financial covenants under the term loan facility required a leverage ratio of 3.50 to 1.00 and an interest coverage ratio of 3.00 to 1.00. We were in compliance with all applicable covenants as of March 31, 2021. Derivative Agreements We have interest rate swap agreements with financial institutions to hedge changes in cash flows attributable to interest rate risk on a portion of our variable-rate debt instruments. Net amounts to be received or paid under the swap agreements are reflected as adjustments to interest expense. Since we have designated the interest rate swap agreements as portfolio cash flow hedges, unrealized gains or losses resulting from adjusting the swaps to fair value are recorded as components of other comprehensive income (loss). The fair values of our interest rate swaps were determined based on the present value of the estimated future net cash flows using implied rates in the applicable yield curve as of the valuation date. These derivative instruments were classified within Level 2 of the valuation hierarchy. The table below presents information about our derivative financial instruments, designated as cash flow hedges, included in the consolidated balance sheets:
|  |  |  |  |  |  |  | Fair Values
