On September 21, 2021, the Company issued $700.0 million of 3.05% senior notes due 2051 through a registered public offering, for the purpose of refinancing its $700.0 million of 4.50% notes due November 1, 2023. On October 8, 2021, the Company completed the redemption of the old 4.50% notes for $769.8 million, which included a redemption premium of $56.1 million and $13.7 million of accrued and unpaid interest. The redemption of the old 4.50% notes also included a $1.4 million write-off of the remaining balance of unamortized debt issuance costs and a $0.5 million write-off of the remaining balance of unamortized debt discount. PCA used the proceeds of the offering of the new 3.05% notes and cash on hand to fund the redemption and the $7.7 million of debt issuance costs associated with the new notes. The debt issuance costs are amortized to interest expense using the effective interest method over the term of the notes.

As of December 31, 2021, the details of our borrowings were as follows:

•Senior Unsecured Credit Agreement. On June 8, 2021, we entered into a revolving credit agreement with various financial institutions (the "New Revolving Credit Agreement"), which replaced the old Credit Agreement, dated August 29, 2016 (the "Old Credit Agreement"). The Old Credit Agreement was scheduled to terminate on August 29, 2021. Loans under the New Revolving Credit Agreement bear interest at LIBOR plus an applicable margin based upon the public ratings of PCA's senior long-term unsecured debt or PCA's gross leverage ratio. The New Revolving Credit Agreement is a $350 million unsecured revolving credit facility, which has a five-year term and is available for borrowings on a revolving basis for general corporate purposes. At December 31, 2021, unused borrowing capacity was $323.2 million, which includes various outstanding letters of credit. The outstanding letters of credit were primarily for workers compensation. We are required to pay commitment fees on the unused portions of the credit facility.

•4.50% Senior Notes. On October 22, 2013, we issued $700.0 million of 4.50% senior notes due November 1, 2023, through a registered public offering. The senior notes were paid off on October 8, 2021 with the proceeds received from the September 2021 offering discussed above and cash on hand.

•3.65% Senior Notes. On September 5, 2014, we issued $400.0 million of 3.65% senior notes due September 15, 2024, through a registered public offering.

•3.40% Senior Notes. On December 13, 2017, we issued $500.0 million of 3.40% senior notes due December 15, 2027, through a registered public offering.

•3.00% Senior Notes. On November 21, 2019, we issued $500.0 million of 3.00% senior notes due December 15, 2029, through a registered public offering.

•4.05% Senior Notes. On November 21, 2019, we issued $400.0 million of 4.05% senior notes due December 15, 2049, through a registered public offering.

•3.05% Senior Notes. On September 21, 2021, we issued $700.0 million of 3.05% senior notes due October 1, 2051, through a registered public offering.

The instruments governing our indebtedness contain financial and other covenants that limit the ability of PCA and its subsidiaries to enter into sale and leaseback transactions, incur liens, incur indebtedness at the subsidiary level, enter into certain transactions with affiliates, merge or consolidate with any other person or sell or otherwise dispose of all or substantially all of our assets. Our credit facility also requires us to comply with certain financial covenants, including maintaining a minimum interest coverage ratio and a maximum leverage ratio. A failure to comply with these restrictions could lead to an event of default, which could result in an acceleration of any outstanding indebtedness and/or prohibit us from drawing on the revolving credit facility. An acceleration under the revolving credit facility may also constitute an event of default under the senior notes indenture. At December 31, 2021, we were in compliance with these covenants.

At December 31, 2021, we have $2,491.0 million of fixed-rate senior notes outstanding. At December 31, 2021, the fair value of our fixed-rate debt was estimated to be $2,650.1 million. The difference between the book value and fair value is due to the difference between the period-end market interest rate and the stated rate of our fixed-rate debt. We estimated the fair value of our fixed-rate debt using quoted market prices (Level 2 inputs), discussed further in Note 2, Summary of Significant Accounting Policies.

Repayments, Interest, and Other

In October 2021, we used the net proceeds from the September 2021 offering of the new 3.05% notes and cash on hand to redeem the 4.50% notes. We completed the redemption of the old 4.50% notes for $769.8 million, which included a redemption premium and accrued and unpaid interest.

In 2020, we did not repay any outstanding debt, as we did not have any maturities of our Senior Notes during 2020.

In December 2019, we used the net proceeds from the November 2019 offering of the new 3.00% and 4.05% notes and cash on hand to redeem the two series of old notes (aggregate principal amount of $900 million) outstanding at the time. We completed the redemption of those old notes for $928.4 million, which included redemption premiums and accrued and unpaid interest.

As of December 31, 2021, annual principal maturities for debt, excluding unamortized debt discount, are: none for 2022 through 2023, $400.0 million for 2024; none for 2025; and $2.1 billion for 2026 and thereafter.

Interest payments paid in connection with the Company’s debt obligations for the years ended December 31, 2021, 2020, and 2019 were $149.6 million (including redemption premiums of $56.1 million), $97.0 million, and $114.0 million (including redemption premiums of $22.2 million), respectively. As of December 31, 2021, the estimated future interest payments for the Company's debt obligations are: $84.7 million for 2022; $84.2 million for 2023 and 2024; $69.6 million for 2025; and $1.0 billion for 2026 and thereafter.

Included in interest expense, net, are amortization of financing costs and, for 2019, amortization of treasury lock settlements. Amortization of financing costs in 2021, 2020, and 2019 was $3.4 million (including a $1.4 million write-off of deferred debt issuance costs related to the October 2021 debt refinancing), $2.0 million, and $4.5 million (including a $1.8 million write-off of deferred debt issuance costs related to the November 2019 debt refinancing), respectively. Amortization of treasury lock settlements was an $18.2 million net loss in 2019 (including a $13.1 million write-off of the remaining balance for treasury locks related to the November 2019 debt refinancing).
