In addition, the covenants included in the indentures governing the senior unsecured notes contain provisions that allow the Company to satisfy the Partnership’s reporting obligations under the indenture, as long as any such financial information of the Company contains information reasonably sufficient to identify the material differences, if any, between the financial information of the Company, on the one hand, and the Partnership and its subsidiaries on a stand-alone basis, on the other hand and the Company does not directly own capital stock of any person other than the Partnership and its subsidiaries, or material business operations that would not be consolidated with the financial results of the Partnership and its subsidiaries.

Other than the interest in the Partnership and the effect of federal and state income taxes that are recognized at the Company level, there are no material differences between the consolidated financial statements of the Partnership and the consolidated financial statements of the Company. Credit Facilities As of June 30, 2023, the Partnership had $1.4 billion senior secured credit facilities (the “Credit Facilities”) consisting of a $1.0 billion 5-year revolving credit facility and a $400.0 million 5‑year Term Loan A facility. The Credit Facilities mature in July 2027. Facility fees accrue on the total capacity of the revolving credit facility. Borrowings under the 5-year Term Loan A facility generally bear interest at Secured Overnight Financing Rate (”SOFR”) plus the applicable margin ranging from 1.65% to 2.55%, while the applicable margin for the 5‑year syndicated revolving credit facility ranges from 1.375% to 2.050%. Pricing levels for the facility fee and interest rate margins are based on the Partnership’s ratio of total debt to EBITDA (as defined in the Credit Facilities). If the Partnership obtains an investment grade credit rating, the pricing levels will be based on the Partnership’s credit ratings in effect from time to time. As of June 30, 2023, borrowings of $198.0 million were drawn and outstanding under the Partnership’s revolving credit facility, and borrowings of $400.0 million, excluding deferred issuance costs, were drawn and outstanding under the Partnership’s Term Loan A facility. The Credit Facilities can be used for borrowings and letters of credit for general corporate purposes. The Credit Facilities are guaranteed by each direct and indirect wholly owned material domestic subsidiary of the Partnership, and are secured by first priority perfected liens on substantially all of the presently owned and after-acquired assets of the Partnership and its direct and indirect wholly owned material domestic subsidiaries, including equity interests directly owned by such entities, subject to certain customary exclusions. The Credit Facilities contain representations and warranties, affirmative and negative covenants and events of default that the Partnership considers to be customary for an agreement of this type, including a covenant that requires the Partnership to maintain a ratio of total debt to EBITDA (as defined in the Credit Facilities) for the prior four fiscal quarters of not greater than 5.00 to 1.00 as of the last day of each fiscal quarter (5.50 to 1.00 during the specified period following certain acquisitions) and, prior to the Partnership obtaining an investment grade credit rating, a ratio of secured debt to EBITDA for the prior four fiscal quarters of not greater than 4.00 to 1.00 as of the last day of each fiscal quarter. As of June 30, 2023, the Partnership was in compliance with these financial covenants. Fair Value Measurement At June 30, 2023, our total debt had a carrying value of $3,068.7 million and had a fair value of approximately $2,924.3 million, based on Level 2 inputs in the fair value measurement hierarchy. The carrying value of the amounts under the Term Loan A facility and revolving credit facility at June 30, 2023, approximated their fair value. Any changes in interest rates do not impact cash outflows associated with fixed rate interest payments or settlement of debt principal, unless a debt instrument is repurchased prior to maturity.
