In advance of the Merger, in August 2019, the Company, our Operating Company and PK Domestic entered into a delayed draw term loan agreement (the “2019 Term Facility”). In September 2019, the 2019 Term Facility was fully drawn to fund the Merger and was partially repaid in December 2019. To hedge the interest rate risk on a portion of the 2019 Term Facility, we assumed an interest rate swap from Chesapeake in connection with the Merger, which is designated as a cash flow hedge. The interest rate swap requires us to pay fixed interest of 1.86% per annum maturing on April 21, 2022 on a notional amount of $225 million, in exchange for floating rate interest equal to one-month LIBOR.

In March 2020, we fully drew down our $1 billion Revolver as a precautionary measure to increase liquidity and preserve financial flexibility in connection with the economic effect of COVID-19. We subsequently repaid $399 million of the Revolver using $299 million of the proceeds from the issuance of the 2025 Senior Secured Notes and 2028 Senior Secured Notes and $100 million of existing cash. We also used $631 million of the proceeds from the issuance of the 2028 Senior Secured Notes to repay all of the amounts outstanding under our 2016 Term Loan.

In May 2020, in order to maintain compliance under our credit and term loan facilities in future quarters, we amended our credit and term loan facilities to suspend compliance with all existing financial covenants tested through and including March 31, 2021 and to adjust the levels of particular financial covenants after such period. In September 2020, we further amended our Revolver and 2019 Term Facility to extend the waiver period for the testing of the financial covenants to the date the financial statements are delivered for the quarter ended March 31, 2022. As part of the amendment process, we (i) increased commitments under the Revolver by $75 million to $1.075 billion and extended the maturity date with respect to $901 million of the aggregate commitments for two years to December 2023, including all $75 million of the increased Revolver commitments, (ii) extended the temporary periods for which certain financial covenants are adjusted once quarterly testing of financial covenants resumes, (iii) increased the mandatory repayment carve out for equity issuances from $500 million to $1 billion, so long as proceeds from the issuances are used for capital expenditures and hotel acquisitions that become part of the unencumbered pool, (iv) maintained the existing guarantees by certain Park-affiliated entities until repayment of the Revolver and 2019 Term Facility and existing pledges of equity interests in Park-affiliated entities owning certain unencumbered assets during the extended waiver period and until the ratio of net debt to EBITDA falls below 6.50x for two consecutive quarters, (v) extended the minimum liquidity covenant through December 2022 and increased the minimum liquidity required to be maintained through December 24, 2021 from $200 million to $200 million plus 50% of the Revolver commitments that mature in December 2021 (which minimum liquidity covenant amount as of September 30, 2020 was $287 million), (vi) obtained the ability to pay a $0.01 per share per fiscal quarter dividend during the extended waiver period and (vii) modified certain restrictions and covenants for the duration of the extended waiver period, including certain mandatory prepayments. We incurred $6 million of fees related to these amendments during the nine months ended September 30, 2020 that were recognized as deferred financing costs.

In May 2020, our Operating Company, PK Domestic and PK Finance issued an aggregate of $650 million of 2025 Senior Secured Notes. We set aside $219 million of the net proceeds to partially repay the Revolver, $69 million to partially repay the 2016 Term Loan and the remainder was used for general corporate purposes. The 2025 Senior Secured Notes bear interest at a rate of 7.500% per annum, payable semi-annually in arrears on June 1 and December 1 of each year, beginning December 1, 2020. The 2025 Senior Secured Notes will mature on June 1, 2025. We capitalized $13 million of issuance costs during the three months ended June 30, 2020.

We may redeem the 2025 Senior Secured Notes at any time prior to June 1, 2022, in whole or in part, at a redemption price equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the redemption date plus a make-whole premium. On or after June 1, 2022, we may redeem the 2025 Senior Secured Notes, in whole or in part, at the applicable redemption prices set forth in the indenture. On or after June 1, 2024, we may redeem the 2025 Senior Secured Notes at 100% of the principal amount, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. In addition, before June 1, 2022, we may redeem up to 40% of the 2025 Senior Secured Notes with the net cash proceeds from certain equity offerings at a redemption price of 107.500% of the principal amount redeemed.

In September 2020, our Operating Company, PK Domestic LLC and the PK Finance issued an aggregate of $725 million of 2028 Senior Secured Notes. The 2028 Senior Secured Notes bear interest at a rate of 5.875% per annum, payable semi-annually in arrears on April 1 and October 1 of each year beginning April 1, 2021. Net proceeds were used to repay the 2016 Term Loan in full and to repay $80 million of our outstanding balance under the Revolver, which may be redrawn. We capitalized $13 million of issuance costs during the three months ended September 30, 2020.

We may redeem the 2028 Senior Secured Notes at any time prior to October 1, 2023, in whole or in part, at a redemption price equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the redemption date plus a make-whole premium. On or after October 1, 2023, we may redeem the 2028 Senior Secured Notes, in whole or in part, at the applicable redemption prices set forth in the indenture. On or after October 1, 2025, we may redeem the 2028 Senior Secured Notes at 100% of the principal amount, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. In addition, before October 1, 2023, we may redeem up to 40% of the 2028 Senior Secured Notes with the net cash proceeds from certain equity offerings at a redemption price of 105.875% of the principal amount redeemed.

Both the 2025 Senior Secured Notes and the 2028 Senior Secured Notes (collectively, the “Senior Secured Notes”) are guaranteed by us and by the subsidiaries of our Operating Company that also guarantee indebtedness under our credit facilities and the guarantees are full and unconditional and joint and several. The Senior Secured Notes are secured, subject to permitted liens, by a first priority security interest in all of the capital stock of certain wholly-owned subsidiaries of certain of the guarantors and PK Domestic, which collateral also secures the obligations under our credit and term loan facilities on a first priority basis. The indentures governing the Senior Secured Notes contain customary covenants that limit the issuers’ ability and, in certain instances, the ability of the issuers’ subsidiaries, to borrow money, create liens on assets, make distributions and pay dividends on or redeem or repurchase stock, make certain types of investments, sell stock in certain subsidiaries, enter into agreements that restrict dividends or other payments from subsidiaries, enter into transactions with affiliates, issue guarantees of indebtedness, and sell assets or merge with other companies. These covenants are subject to a number of exceptions and qualifications, including the ability to declare or pay any cash dividend or make any cash distribution to us to the extent necessary for us to fund a dividend or distribution by us that we believe is necessary to maintain our status as a REIT or to avoid payment of any tax for any calendar year that could be avoided by reason of such distribution, and the ability to make certain restricted payments not to exceed $100.0 million, plus 95% of our cumulative Funds From Operations (as defined in the indenture), plus the aggregate net proceeds from (i) the sale of certain equity interests in, (ii) capital contributions to, and (iii) certain convertible indebtedness of the Operating Company. In addition, the indenture requires our Operating Company to maintain total unencumbered assets as of each fiscal quarter of at least 150% of total unsecured indebtedness, in each case calculated on a consolidated basis.

We are required to deposit with lenders certain cash reserves for restricted uses. As of September 30, 2020 and December 31, 2019, our condensed consolidated balance sheets included $7 million and $13 million of restricted cash, respectively, related to our CMBS loans and mortgage loans. During the second and third quarters of 2020, we amended certain mortgage loan agreements to defer interest or interest and principal payments for three to six months and temporarily suspend required cash reserves.

The contractual maturities of our debt, assuming the exercise of all extensions that are exercisable solely at our option, as of September 30, 2020 were:
