The Amendment provides for a waiver of the foregoing financial covenants through March 31, 2021 and ending on April 1, 2021 (the “Temporary Waiver Period”) and amends covenant computations for the three months ended June 30, 2021 and September 30, 2021. In addition, the Amendment contains a covenant that we must maintain unrestricted liquidity (in the form of unrestricted cash on hand or undrawn availability under the Revolver) of at least $100 million. Following the Temporary Waiver Period, in the event we are unable to comply with the Credit Agreement’s financial covenants, we expect to further amend the Credit Agreement or take other mitigating actions prior to a potential breach.
We may elect to terminate the Temporary Waiver Period prior to expiration. Upon expiration or termination of the Temporary Waiver Period, we will calculate compliance with the financial covenants in the Credit Agreement using a designated annualized calculation based on our most recently completed fiscal quarter or quarters, as applicable. Pursuant to the Amendment, we are required to use any proceeds from borrowings drawn during the Temporary Waiver Period to fund operating expenses, debt service of the Company and its subsidiaries, and permitted capital expenditures and investments.
If an event of default shall occur and be continuing under the Credit Agreement, the commitments under the Credit Agreement may be terminated and the principal amount outstanding under the Credit Agreement, together with all accrued unpaid interest and other amounts owing in respect thereof, may be declared immediately due and payable.
Revolving Credit Facility. Pursuant to the Credit Agreement, we extended the maturity date of the Revolver to March 31, 2024, with two additional six-month extension options, at our election. Borrowings under the Revolver bear interest at an annual rate equal to, at our option, either (i) LIBOR plus the applicable margin ranging from 1.40% to 1.95%, dependent upon our funded debt to total asset value ratio (as defined in the Credit Agreement) or (ii) a base rate as set forth in the Credit Agreement. At June 30, 2020, the interest rate on the Revolver was, and during the Temporary Waiver Period will be, LIBOR plus 1.95%. Principal is payable in full at maturity.
At June 30, 2020, $25.0 million of borrowings were outstanding under the Revolver, and the lending banks had issued $0.9 million of letters of credit under the Credit Agreement, which left $674.1 million of availability under the Revolver (subject to the satisfaction of debt incurrence tests under the indentures governing our $400 million in aggregate principal amount of senior notes due 2023 (the “$400 Million 5% Senior Notes”) and our $700 million in aggregate principal amount of senior notes due 2027 (the “$700 Million 4.75% Senior Notes”), which we met at June 30, 2020).
Term Loan A Facility. Pursuant to the Credit Agreement, the Term Loan A was increased from $200 million to $300 million and the maturity date was extended to March 31, 2025. Borrowings bear interest at an annual rate equal to, at our option, either (i) LIBOR plus the applicable margin ranging from 1.35% to 1.90%, dependent upon our funded debt to total asset value ratio (as defined in the Credit Agreement) or (ii) a base rate as set forth in the Credit Agreement. At June 30, 2020, the interest rate on the Term Loan A was, and during the Temporary Waiver Period will be, LIBOR plus 1.90%. Amounts borrowed under the Term Loan A that are repaid or prepaid may not be reborrowed. Net proceeds from the increase in the Term Loan A pursuant to the Credit Agreement were approximately $94 million and, along with cash on hand, were used to repay $100 million of the outstanding indebtedness under the Term Loan B.
Term Loan B Facility. The Term Loan B has a maturity date of May 11, 2024. The applicable interest rate margins for borrowings under the Term Loan B are, at our option, either (i) LIBOR plus 2.00% or (ii) a base rate as set forth in the Credit Agreement. At June 30, 2020, the interest rate on the Term Loan B was LIBOR plus 2.00%. In October 2019, we entered into four interest rate swaps with a total notional amount of $350.0 million to fix the LIBOR portion of the interest rate, at rates between 1.2235% and 1.2315%, through May 11, 2023. We have designated these interest rate swaps as effective cash flow hedges. The Term Loan B amortizes in equal quarterly installments in aggregate annual amounts equal to 1.0% of the original principal amount of $500.0 million, with the balance due at maturity. In addition, if for any fiscal year, there is Excess Cash Flow (as defined in the Credit Agreement), an additional principal amount is required. Amounts borrowed under the Term Loan B that are repaid or prepaid may not be reborrowed. The Credit Agreement did not change the maturity date or applicable margin on interest rates for the Term Loan B. At June 30, 2020, $383.8 million in borrowings were outstanding under the Term Loan B.
$700 Million 4.75% Senior Notes. In September 2019, the Operating Partnership and Finco completed the private placement of $500.0 million in aggregate principal amount of senior notes due 2027, which are guaranteed by the Company and its subsidiaries that guarantee the Credit Agreement. The $500 Million 4.75% Senior Notes and
