^(*)	Represents the fair value adjustments for interest rate swap contracts with an aggregate notional amount of $300.0 million designated as fair value hedges of our fixed-rate 2041 Notes. See Note 4, Derivative Instruments, for a discussion of the Company's interest rate swaps.

The Notes above are the Company’s senior unsecured and unsubordinated obligations, ranking equally in right of payment to all of the Company’s existing and future senior unsecured and unsubordinated indebtedness, and senior in right of payment to any of the Company’s future indebtedness that is expressly subordinated to the Notes.

Interest on the Notes is payable in cash semiannually. The effective interest rates for the Notes include the interest on the Notes, accretion of the discount, and amortization of issuance costs. The indentures that govern the Notes also contain various covenants, including limitations on the Company's ability to incur liens or enter into sale-leaseback transactions over certain dollar thresholds.

As of March 31, 2020, the Company was in compliance with all covenants in the indentures governing the Notes.

The credit facility will terminate in April 2024, subject to a one-year maturity extension option.
