As of December 31, 2022 there was a $598.0 million outstanding revolver loan balance. There was no outstanding revolver loan balance as of December 31, 2021. During the year ended December 31, 2022, the Company reclassified the debt issuance costs associated with the revolver loan to a contra account to directly offset the loan balance in other current liabilities on the Company's consolidated balance sheets. As of December 31, 2022, the Company had approximately $1.3 million debt issuance costs associated with the revolver loan that were classified as an offset to other current liabilities. Prior to 2022, the debt issuance costs associated with the revolver load were included in other current assets and other assets on the Company's consolidated balance sheets. As of December 31, 2021, the Company had approximately $2.0 million and $1.6 million of debt issuance costs associated with the revolver loan that were classified as other current assets and other assets, respectively.

3.875% Senior Unsecured Notes due 2028

On August 7, 2020, the Company completed its offering of $450.0 million aggregate principal amount of 3.875% Senior Unsecured Notes due 2028 (the "Senior Unsecured Notes") of which the majority of the net proceeds were used to pay down the Revolving Credit Facility (as defined below). Interest on the Senior Unsecured Notes is payable on February 15th and August 15th of each year until maturity, beginning on February 15, 2021. The Senior Unsecured Notes will mature on August 15, 2028.

On or after August 15, 2023, the Company may redeem the Senior Unsecured Notes, in whole or in part, at the redemption prices set forth in the related Indenture, plus accrued and unpaid interest. Prior to August 15, 2023 the Company may redeem all or a portion of the Senior Unsecured Notes at a redemption price equal to 100% of the principal amount of the Senior Unsecured Notes plus a “make-whole” premium and accrued and unpaid interest. Prior to August 15, 2023, the Company may redeem up to 40% of the aggregate principal amount of the Senior Unsecured Notes using the net cash proceeds of certain equity offerings at the redemption price set forth in the related Indenture. Upon the occurrence of a change of control, the Company must offer to repurchase the Senior Unsecured Notes at a purchase price of 101% of the principal amount of such Senior Unsecured Notes plus accrued and unpaid interest.

Negative covenants in the Indenture governing the Senior Unsecured Notes, among other things, limit the ability of the Company to incur indebtedness and liens, dispose of assets, make investments, enter into certain merger or consolidation transactions and make restricted payments.

Senior Secured Credit Agreement

Also on August 7, 2020, the Company entered into a Second Amendment (the "Second Credit Agreement Amendment") to its senior secured credit agreement, dated October 15, 2018, with multiple lending institutions relating to the Company’s senior secured credit facilities (the Credit Agreement, and as amended, the Amended Credit Agreement), consisting of Revolving Credit Facility and Term Loan Facility, and together with the Revolving Credit Facility, the Senior Secured Credit Facilities. The Second Credit Agreement Amendment amended, among other things, the definition of incremental facilities limit, the consolidated net leverage ratio financial covenant by increasing the maximum level, increased the permissible applicable margins based on the Company’s consolidated net leverage ratio and increased the commitment fee that the Company is required to pay in respect of the average daily unused commitments under the Revolving Credit Facility, depending on the Company’s consolidated net leverage ratio.

The Amended Credit Agreement includes (i) a Revolving Credit Facility of $600.0 million with a maturity date of October 13, 2023, and (ii) a Term Loan Facility with a principal amount of $450.0 million. The Company may request incremental term loan facilities or increases in the Revolving Credit Facility (each an Incremental Loan) as long as certain requirements involving our net leverage ratio will be maintained on a pro forma basis. Borrowings under the Revolving Credit Facility and the Term Loan Facility bear interest at a rate per annum equal to (a) a eurocurrency rate plus a margin ranging from 1.3% to 2.3% per annum, depending on the Company's consolidated net leverage ratio or (b) a base rate (which is the highest of the prime rate, the federal funds rate plus 0.5%, and a eurocurrency rate for an interest period of one month plus 1.0% plus a margin ranging from 0.3% to 1.3%, depending on the Company's consolidated net leverage ratio. The Company is required to make quarterly payments on the last business day of each calendar quarter under the Amended Credit Agreement for accrued and unpaid interest on the outstanding principal balance, based on the above interest rates. In addition, the Company is required to pay commitment fees ranging from 0.2% to 0.4% per annum, depending on the Company's consolidated net leverage ratio, for the average daily unused commitments under the Revolving Credit Facility. The Company is to repay the outstanding principal amount of the Term Loan Facility in quarterly installments on the last business day of each calendar quarter based on an annual percentage equal to 2.5% of the original principal amount of the Term Loan Facility during each of the first two years of the Term Loan Facility, 5.0% of the original principal amount of the Term Loan Facility during the third year of the Term Loan Facility and 7.5% of the original principal amount of the Term Loan Facility during each year of the remainder of the term of the Term Loan Facility until the maturity date of the Term Loan Facility, at which time the entire unpaid principal balance of the Term Loan Facility will be due and payable. The Company has the right to prepay the Term Loan Facility without premium or penalty. The Revolving Credit Facility and the Term Loan Facility mature on October 13, 2023.

The Amended Credit Agreement also requires mandatory prepayments of the Term Loan Facility in the event the Company or its subsidiaries (a) incur indebtedness not otherwise permitted under the Amended Credit Agreement or (b) receive cash proceeds in excess of $100.0 million during the term of the Credit Agreement from certain dispositions of property or from casualty events involving their property, subject to certain reinvestment rights. The financial covenants under the Amended Credit Agreement currently require the quarterly presentation of a minimum consolidated 12-month rolling debt service coverage ratio of 2.5 to 1.0, and a maximum consolidated net leverage ratio of 4.5 to 1.0 (subject to an increase to 5.0 to 1.0 for an applicable four quarter period, at the election of the Company, in connection with a permitted acquisition having an aggregate consideration in excess of $75.0 million). Negative covenants in the Amended Credit Agreement, among other things, limit the ability of the Company to incur indebtedness and liens, dispose of assets, make investments, enter into certain merger or consolidation transactions and make restricted payments.

On February 14, 2023, the Company entered into a Consent, Limited Waiver, and Third Amendment to the Amended and Restated Credit Agreement relating to the Senior Secured Credit Facilities. Pursuant to the Third Credit Agreement Amendment, the requisite lenders consented to our sale of our travel health business to Bavarian Nordic substantially in accordance with the terms of the Sale Agreement. The proceeds from the transaction will be deposited into a cash collateral account with the Administrative Agent and will, unless otherwise agreed to by the Company and the requisite lenders, be used to repay the outstanding Term Loan Facility on the expiration of the Limited Waiver (as described below). We currently expect the transaction to close in the second quarter of 2023, but we can provide no assurance that the transaction will close prior to the October 2023 maturity of the Term Loan Facility, or at all.

Pursuant to the Third Credit Agreement Amendment the requisite lenders have agreed to a limited waiver of any defaults or events of default that result from (a) any violation of the financial covenants set forth in the Senior Secured Credit Facilities with respect to the fiscal quarters ending December 31, 2022 and March 31, 2023 and (b) the going concern qualification or exception contained in the audited financial statements for the fiscal year ending December 31, 2022. This limited waiver will expire on the earlier to occur of (i) any other event of default and (ii) April 17, 2023. During this period the Company is working with lenders under the Senior Secured Credit Facilities in connection with replacing such facilities before their October 2023 maturity with revised terms and conditions. The Company does not expect to be in compliance with debt covenants in future periods without additional sources of liquidity or future amendments to the Credit Agreement. See Footnote 3 "Summary of significant accounting policies" for Going Concern considerations related to noncompliance with our debt covenants and the limited waiver.
