On July 1, 2021, we terminated our previous revolving credit facility and entered into an unsecured $750.0 million revolving credit facility (the Revolving Credit Facility), which terminates on July 1, 2026. The Revolving Credit Facility also provides the Company the option to increase the borrowing capacity by up to $375.0 million (for a total borrowing capacity of $1,125 million), provided that the existing lenders, or new lenders, agree to such increase. The Revolving Credit Facility includes a $40.0 million letter of credit facility and a swingline loan sub-facility of $25.0 million.

The Revolving Credit Facility contains customary covenants for an unsecured investment-grade facility, including covenants that restrict the Company’s and/or its subsidiaries’ ability to incur additional debt; encumber assets; merge with or transfer or sell assets to other persons; and enter into certain affiliate transactions. The Revolving Credit Facility also requires the Company to maintain at the end of each fiscal quarter a Leverage Ratio of 3.50:1.00 or less and an Interest Coverage Ratio (both ratios, as defined in the Revolving Credit Facility) equal to or greater than 2.50 to 1.00 (collectively, the Financial Covenants).

At the Company’s option, principal amounts outstanding under the Revolving Credit Facility bear interest at a variable rate equal to either (i) the Adjusted LIBO Rate (as defined in the Revolving Credit Facility) plus an agreed spread (ranging from 100 to 162.5 basis points, which is established based on the Company's credit rating); or (ii) an Alternate Base Rate (as defined in the Revolving Credit Facility), which is the highest of (a) the Prime Rate (as defined in the Revolving Credit Facility) in effect on any applicable day, (b) the NYFRB Rate (as defined in the Revolving Credit Facility) in effect on any applicable day, plus ½ of 1%, and (c) the Adjusted LIBO Rate for a one-month interest period on any applicable day, or if such day is not a business day, the immediately preceding business day, plus 1.0%, in each case plus an agreed upon spread (ranging from 0 to 62.5 basis points) which is established quarterly based on the Company's credit rating. The Company is also required to pay a facility fee on unused available borrowings under the Revolving Credit Facility ranging from 9 to 22.5 basis points which is established based on the Company's then credit rating.

The Company pays each lender a participation fee with respect to such lender’s participations in letters of credit, which fee accrues at the same Applicable Rate (as defined in the Revolving Credit Facility) used to determine the interest rate applicable to Eurodollar Revolving Loans (as defined in the Revolving Credit Facility) plus a fronting fee for each letter of credit issued by the issuing bank in an amount equal to 12.5 basis points per annum on the daily maximum amount then available to be drawn under such letter of credit. The Company also pays each issuing bank such bank’s standard fees with respect to issuance, amendment or extensions of letters of credit and other processing fees, and other standard costs and charges relating to such issuing bank’s letters of credit from time to time.

There was $75.0 million of outstanding borrowings under the Revolving Credit Facility, plus $5.0 million outstanding letters of credit as of September 30, 2021, leaving us with $670.0 million of available borrowings under the Revolving Credit Facility, net of the outstanding letters of credit. We were in compliance with all Financial Covenants on September 30, 2021; therefore, all $670.0 million is available for future borrowings.

On July 1, 2021, we issued $750.0 million aggregate principal amount of 2.500% senior notes due July 2031 (the 2.500% Senior Unsecured Notes). The 2.500% Senior Unsecured Notes are senior unsecured obligations of the Company and are not guaranteed by any of our subsidiaries. The 2.500% Senior Unsecured Notes were issued net of original issue discount of $6.3 million and have an effective interest rate of approximately 2.6%. The original issue discount is being amortized by the effective interest method over the ten-year term of the notes. The 2.500% Senior Unsecured Notes are redeemable prior to April 1, 2031 at a redemption price equal to 100% of the aggregate principal amount of the 2.500% Senior Unsecured Notes being redeemed, plus the present value of remaining scheduled payments of principal and interest from the applicable redemption date to April 1, 2031, discounted to the redemption date on a semi-annual basis at the Treasury rate plus 20 basis points. The 2.500% Senior Unsecured Notes are redeemable on or after April 1, 2031 at a redemption price equal to 100% of the aggregate principal amount of the 2.500% Senior Unsecured Notes being redeemed, plus accrued and unpaid interest to, but excluding, the applicable redemption date. If we experience certain change of control triggering events, we would be required to offer to repurchase the 2.500% Senior Unsecured Notes at a purchase price equal to 101% of the aggregate principal amount of the 2.500% Senior Unsecured Notes being repurchased, plus accrued and unpaid interest to, but excluding, the applicable redemption date. The indenture governing the 2.500% Senior Unsecured Notes contains certain covenants that limit our ability to create or permit to exist certain liens; enter into sale and leaseback transactions; and consolidate, merge, or transfer all or substantially all of our assets, and provides for certain events of default that, if any occurred, would permit or require the principal of and accrued interest on the 2.500% Senior Unsecured Notes to become or be declared due and payable.

In connection with the issuance of the 2.500% Senior Unsecured Notes on July 1, 2021, we repaid all outstanding amounts under and terminated our $665.0 million term loan credit agreement (the Term Loan Facility). The Term Loan Facility was used to pay a portion of the purchase price for the Kosmos Acquisition and fees and expenses incurred in connection with the Kosmos Acquisition in March 2020. Additionally, on July 19, 2021, (the first business day following the redemption date), we redeemed and paid in full all outstanding amounts due under the $350.0 million aggregate principal amount of 4.500% senior notes (4.500% Senior Unsecured Notes) due August 2026, using proceeds from the 2.500% Senior Unsecured Notes, the Revolving Credit Facility and cash on hand. The 4.500% Senior Unsecured Notes redemption price included all of the outstanding principal and accrued interest through the redemption date of July 17, 2021, as well as an early termination premium of approximately $8.4 million. In connection with the termination and repayment of the Term Loan Facility and the redemption of the 4.500% Senior Unsecured Notes, we expensed approximately $6.1 million of related debt issuance costs in July 2021.
