On February 16, 2021 (the “Fourth Amendment Effective Date”), the Company entered into the fourth amendment (the “Fourth Amendment”) to the Company’s credit agreement (as amended prior to the Fourth Amendment Effective Date (as defined below), the “Credit Agreement”) with Bank of America, N.A. (“Bank of America”), as Administrative Agent, swing-line lender and a letter of credit issuer; Wells Fargo Bank, N.A., as syndication agent; BMO Harris Bank N.A., JPMorgan Chase Bank, N.A., KeyBank National Association and U.S. Bank National Association, as co-documentation agents; Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC, as joint lead arrangers and bookrunners; and the lenders party thereto (the “Lenders”), pursuant to which the Lenders have made available to the Company a senior secured credit facility (the “Senior Credit Facility”). Prior to the Fourth Amendment Effective Date and pursuant to the third amendment (the “Third Amendment”) to the Credit Agreement, which was entered into on May 6, 2020, the Senior Credit Facility permitted aggregate borrowings of $595.0 million consisting of (i) a revolving credit facility of up to $370.0 million at any time outstanding, which includes a letter of credit facility that is limited to $100.0 million at any time outstanding, and (ii) a term loan facility of $225.0 million (the entire principal amount of which the Company withdrew November 30, 2018). Pursuant to the Credit Agreement as amended by the Fourth Amendment (the “Amended Credit Agreement”), the aggregate commitments under the revolving credit facility decreased by $45.0 million to $325.0 million.

Borrowings under the Senior Credit Facility bear interest, at the Company’s option, at a rate per annum based on the Company’s consolidated total debt to EBITDA ratio for the 12-month period ending as of the last day of the immediately preceding fiscal quarter, determined in accordance with (i) the applicable pricing levels set forth in the Credit Agreement (the “Applicable Margin”) for London Interbank Offered Rate (“LIBOR”) loans, subject to a “floor” on LIBOR of 1.00%, or a comparable or successor rate to LIBOR approved by Bank of America, plus the applicable LIBOR rate, or (ii) the Applicable Margin for base rate loans plus the highest of (x) the federal funds rate plus 0.5%, (y) the Bank of America prime rate and (z) a daily rate equal to the applicable LIBOR rate plus 1.0%, except that the Fourth Amendment provided that, for the period from May 6, 2020 until the date on which the Company delivers a compliance certificate for the fiscal quarter ending June 30, 2022, (i) the interest rate applicable to both the term loan and revolving credit facilities was fixed at LIBOR plus 2.75% per annum and (ii) the per annum rate applicable to unused revolving credit facility commitments was fixed at 0.375% (the “Fixed Margin Rates”).

Also pursuant to the Fourth Amendment, (a) the Company is subject to a Minimum Liquidity (as described in the Amended Credit Agreement) test that requires the Company to have liquidity of at least $40.0 million at each of March 31, 2021 and June 30, 2021, and (b) the Company is subject to a requirement that, at any time cash on hand exceeds $40.0 million for a period of three consecutive business days, the Company must repay revolving loans in an amount equal to such excess. Certain other negative and financial covenants were amended, which included restrictions on certain Investments, Permitted Acquisitions, Restricted Payments and Prepayments of Subordinated Debt (each as defined in the Amended Credit Agreement), through the delivery of the compliance certificate for the fiscal quarters ending March 31, 2022 or June 30, 2022, as applicable.

Prior to the Fourth Amendment Effective Date, the Company was required to maintain a maximum consolidated total debt to EBITDA ratio of between 5.50:1.0 and 3.50:1.0 (with such ratio being waived for the fiscal quarter ended June 30, 2020 and with certain step-ups and step-downs described in, and as calculated in accordance with, the Amended Credit Agreement). In addition, the Company was required to maintain a minimum consolidated fixed charge coverage ratio of not less than 3.50:1.0 (with certain step-ups and step-downs described in the Amended Credit Agreement). Under the terms of the Fourth Amendment, the maximum consolidated debt to EBITDA ratio is waived for each of the quarters ending March 31, 2021 and June 30, 2021. Starting with the quarter ending September 30, 2021, the Company will be required to maintain a maximum consolidated total debt to EBITDA ratio (as calculated in accordance with the Fourth Amendment) of not greater than 5.25:1.0 (with certain step-downs described in the Amended Credit Agreement). As of March 31, 2021, the Company was required to maintain a minimum consolidated fixed coverage ratio of not less than 1.60:1:0 (with certain step-ups and step-downs described in the Amended Credit Agreement).

During the three months ended March 31, 2021, the Company incurred approximately $1.2 million for fees and other customary closing costs in connection with the Amended Credit Agreement.

Under the terms of the Amended Credit Agreement, term loans under the Senior Credit Facility were subject to scheduled quarterly payments of principal in installments equal to 1.25% of initial aggregate principal amount of such term loan through the first quarter of 2021 and will increase to 1.875% thereafter.

Events of default under the Credit Agreement include failure to pay principal or interest when due, failure to comply with the financial and operational covenants, the occurrence of any cross default event, non-compliance with other loan documents, the occurrence of a change of control event, and bankruptcy and other insolvency events. If an event of default occurs and is continuing, the Administrative Agent can, with the consent of the required Lenders, among others, (i) terminate the commitments under the Credit Agreement, (ii) accelerate and require the Company to repay all the outstanding amounts owed under the Credit Agreement, and (iii) require the Company to cash collateralize any outstanding letters of credit.

Each wholly owned domestic subsidiary of the Company (subject to certain exceptions set forth in the Credit Agreement) has guaranteed all existing and future indebtedness and liabilities of the other guarantors and the Company arising under the Credit Agreement. The Company’s obligations under the Credit Agreement and such domestic subsidiaries’ guaranty obligations are secured by substantially all of their respective assets. The Senior Credit Facility matures on November 30, 2023. The proceeds from the Senior Credit Facility may be used to finance working capital, capital expenditures and acquisitions, as well as for other general corporate purposes. The Amended Credit Agreement did not change the guarantors, collateral, maturity date or permitted uses of proceeds, except as otherwise described above.

As of March 31, 2021, the Company was in compliance with its debt covenants under the Credit Agreement.

At March 31, 2021, the Company had $49.5 million of letters of credit outstanding under the Senior Credit Facility and borrowings against the Senior Credit Facility aggregated to $344.7 million.

The weighted average interest rate on the Company's Senior Credit Facility was 3.6% and 2.6% for the periods ended March 31, 2021 and 2020, respectively. That rate included all outstanding LIBOR contracts and letters of credit. The weighted average interest rate on all outstanding borrowings, not including letters of credit, was 3.8% and 2.7%, at March 31, 2021 and 2020, respectively.

In May 2019, the Company entered into three-year interest rate collar contracts with an aggregate notional amount of $222.3 million and maturity dates of April 2022. The interest rate collars were used to manage interest rate risk associated with variable interest rate borrowings under the Credit Agreement. The interest rate collars established a range where the Company will pay the counterparties if the one-month LIBOR rate falls below the established floor rate, and the counterparties will pay the Company if the one-month LIBOR rate exceeds the established ceiling rate of 2.5%. The interest rate collars settle monthly through the maturity date. No payments or receipts are exchanged on the interest rate collar contracts unless interest rates rise above or fall below the pre-determined ceiling or floor rates. The notional amount amortized consistently with the term loan portion of the Senior Credit Facility under the Credit Agreement prior to the Third Amendment. The fair value of the interest rate collars is a Level 2 fair value measurement, as the fair value is determined based on quoted prices of similar items in active markets. As of March 31, 2021 and December 31, 2020, the liability for interest rate collars of $2.5 million and $3.1 million, respectively, was included in Other noncurrent liabilities in the Condensed Consolidated Balance Sheets. The interest rate collars were classified as cash flow hedges through May 5, 2020.

On May 6, 2020, concurrent with entering into the Third Amendment, the Company de-designated the three-year interest rate collars. Prior to de-designation, the effective portion of the change in the fair value of the interest rate collars was reported in Accumulated other comprehensive loss. Upon de-designation, the balance in Accumulated other comprehensive loss is being reclassified to Other expense (income) in the Condensed Consolidated Statements of Income (Loss) on a straight-line basis through April 2022, which is over the remaining life for which the interest rate collars had previously been designated as cash flow hedges. Changes in the fair value of the interest rate collars after de-designation are included within Other expense (income) in the Condensed Consolidated Statements of Income (Loss). For the three months ended March 31, 2021, $0.6 million of interest was paid for the interest rate collars.

See Note 13. Comprehensive Income (Loss) for the amount of loss recognized in Other Comprehensive income (loss) on the interest rate collars and the loss reclassified from Accumulated other comprehensive loss to the Condensed Consolidated Statements of Income (Loss) during the three months ended March 31, 2021.

The Company acquired Subordinated Convertible Debentures ("Convertible Debentures") as a result of the October 2, 2012 acquisition of Central Parking Corporation. The subordinated debenture holders have the right to redeem the Convertible Debentures for $19.18 per share upon their stated maturity (April 1, 2028) or upon acceleration or earlier repayment of the Convertible Debentures. The Convertible Debentures mature at $25 per share. There were no redemptions of Convertible Debentures during the periods ended March 31, 2021 and December 31, 2020, respectively. The approximate redemption value of the Convertible Debentures outstanding at each of March 31, 2021 and December 31, 2020 was $1.1 million.
