(1)For the Company's senior secured credit facilities and senior notes, fair value estimates are based upon bid and ask quotes, typically a level 2 input. For acquisition obligations and other notes payable, the carrying values presented approximate their estimated fair values, based on estimates of their present values using level 2 interest rate inputs.

(2)The interest rate presented for acquisition obligations and other notes payable is their weighted average interest rate based on the current fixed and LIBOR interest rate components in effect as of September 30, 2021.

(3)Financing lease obligations are measured at their approximate present values at inception. The interest rate presented is the weighted average discount rate embedded in financing leases outstanding. The term of one ground lease runs to 2070, in addition to the other lease maturity dates presented in the table above.

(4)As of September 30, 2021, the carrying amount of the Company's senior secured credit facilities is reduced by a discount of $4,719 and deferred financing costs of $29,340, and the carrying amount of the Company's senior notes is reduced by deferred financing costs of $42,091 and increased by a debt premium of $16,381. As of December 31, 2020, the carrying amount of the Company's senior secured credit facilities is reduced by a discount of $5,461 and deferred financing costs of $35,825, and the carrying amount of the Company's senior notes is reduced by deferred financing costs of $36,431.

During the first nine months of 2021, the Company made regularly scheduled mandatory principal payments under its senior secured credit facilities totaling $65,625 on Term Loan A and $20,574 on Term Loan B-1.

On February 26, 2021, the Company completed an unregistered add-on offering of $1,000,000 aggregate principal amount to the existing 4.625% senior notes due June 1, 2030 (the Additional 2030 Notes) pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended. The Additional 2030 Notes were issued at an offering price of 101.750% of face amount, plus an interest payment advance to the Company for interest that would have accrued from December 1, 2020 (the last interest payment date) through the closing date, and began bearing full six months' semi-annual coupon interest payments as of June 1, 2021. The terms of the Additional 2030 Notes, other than their issue date, offering price and first interest payment date, are identical to the terms of the $1,750,000 principal amount of the Company’s 4.625% senior notes due June 1, 2030 previously issued by the Company on June 9, 2020. The Additional 2030 Notes are unsecured senior obligations and rank equally in right of payment with the Company's existing and future unsecured senior indebtedness. During the nine months ended September 30, 2021, the Company incurred $9,091 in fees and other professional expenses associated with this transaction, which were capitalized and will amortize over the term of the Additional 2030 Notes.

As of September 30, 2021, the Company's 2019 interest rate cap agreements have the economic effect of capping the Company's maximum exposure to LIBOR variable interest rate changes on equivalent amounts of the Company's floating rate debt, including all of Term Loan B-1 and a portion of Term Loan A. The remaining $813,870 outstanding principal balance of Term Loan A is subject to LIBOR-based interest rate volatility. These cap agreements are designated as cash flow hedges and, as a result, changes in the fair values of the cap agreements are reported in other comprehensive income. The original premiums paid for the caps are amortized to debt expense on a straight-line basis over the term of each cap agreement starting from its effective date. These cap agreements do not contain credit risk-contingent features.

The following table summarizes the Company’s interest rate cap agreements outstanding as of September 30, 2021 and December 31, 2020, which are classified in "Other long-term assets" on its consolidated balance sheet:


						Nine months ended September 30, 2021				Fair value
	Notional amount		LIBOR maximum rate	Effective date	Expiration date	Debt expense		Recorded OCI gain		September 30, 2021		December 31, 2020
2019 cap agreements	$	3,500,000	2.00%	6/30/2020	6/30/2024	$	4,132	$	3,284	$	5,955	$	2,671

See Note 11 for further details on amounts reclassified from accumulated other comprehensive loss and recorded as debt expense related to the Company’s interest rate cap agreements for the three and nine months ended September 30, 2021 and 2020.

The Company’s weighted average effective interest rate on its senior secured credit facilities at the end of the third quarter of 2021 was 2.16%, based on the current margins in effect for its senior secured credit facilities as of September 30, 2021, as described above.

As of September 30, 2021, the Company’s interest rates were fixed on approximately 51% of its total debt.

As of September 30, 2021, the Company had an undrawn $1,000,000 revolving line of credit under its senior secured credit facilities.

The Company also had approximately $69,185 in letters of credit outstanding under a separate bilateral secured letter of credit facility as of September 30, 2021.
