________________________________

(*)     Represents the fair value adjustments for interest rate swaps with an aggregate notional amount of $600.0 million. These interest rate swaps convert the fixed interest rates of certain Notes to floating interest rates and are designated as fair value hedges. 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 indenture and the supplemental indentures (together, 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, 2023, the Company was in compliance with all covenants in the indentures governing the Notes.

Revolving Credit Facility

The Company has an unsecured revolving credit facility that will expire in April 2024, which enables borrowings of up to $500.0 million, with an option to increase the amount of the credit facility by up to an additional $200.0 million, subject to the lenders' approval. As of March 31, 2023, the Company was in compliance with all covenants and no amounts were outstanding under its credit facility.
