Five-year Revolving Credit Facility
On June 19, 2018, the Company entered into a Credit Agreement (the “Credit Agreement”) with Wells Fargo Bank, National Association, as administrative agent, and the other lenders party thereto. The Credit Agreement provided for a $1 billion revolving credit facility that matures in June 2023. The borrowings under the Credit Agreement were used to repay in full all outstanding indebtedness under the previous credit agreement. On May 25, 2021, the Company entered into the first amendment to the Credit Agreement to permit the issuance of the Convertible Senior Notes described below. On December 14, 2021, the Company entered into the second amendment to increase its borrowing limit from $1 billion to $1.3 billion, extend the maturity of the Credit Agreement from June 2023 to December 2026, and modified the leverage calculation to differentiate between secured debt and total debt. Revolving loans under the credit facility bear interest, at the Company’s option, at 1) SOFR (subject to a floor rate of zero) plus 10 basis points, or 2) an alternative base rate (which is the greater of Wells Fargo’s Prime Rate, the Federal Funds Rate plus 50 basis points, or SOFR (subject to a floor rate of zero) plus 1.1% , plus, in each case, a margin dependent on the leverage ratio.
The Company is required to make periodic interest payments on borrowed amounts and to pay an annual commitment fee of 15.0 to 30.0 basis points, depending on its leverage ratio. As of December 31, 2023, the Company had $250.0 million drawn on and $1,043.8 million of availability under the revolving credit facility. The ability to use this availability is limited by the leverage ratio covenant described below.
The obligations under the Credit Agreement are guaranteed by the Company’s domestic and certain foreign subsidiaries and subsequently formed or acquired subsidiaries (the “Guarantors”). The obligations under the Credit Agreement are secured by a first-priority security interest in substantially all of the Guarantor’s tangible and intangible personal property and a pledge of the capital stock of permitted borrowers and certain Guarantors.
The Company’s credit facility includes restrictive covenants that, if not met, could lead to renegotiation of its credit facility, a requirement to repay its borrowings, and/or a significant increase in its cost of financing. Restrictive covenants include a minimum interest coverage ratio, a maximum leverage ratio, as well as certain events of default.
Convertible Senior Notes
On May 28, 2021, the Company closed a private offering of $402.5 million aggregate principal amount of the Company’s 0.25% Convertible Senior Notes due 2026 (the “Notes”) to qualified institutional buyers, resulting in net proceeds of approximately $392.2 million after deducting initial purchasers’ discounts of the Notes. Interest on the Notes has accrued from May 28, 2021 and is payable semi-annually in arrears on May 15 and November 15 of each year, beginning on November 15, 2021, at a rate of 0.25% per year. The Notes will mature on May 15, 2026 unless earlier converted, redeemed or repurchased. No sinking fund is provided for the Notes.
The initial conversion rate of the Notes is 5.8958 shares of the Company’s common stock per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $169.61 per share. The conversion rate of the Notes is subject to adjustment upon the occurrence of certain specified events. In addition, upon the occurrence of a make-whole fundamental change (as defined in the indenture governing the Notes (the “Indenture”)) or upon a notice of redemption, the Company will, in certain circumstances, increase the conversion rate for a holder that elects to convert its Notes in connection with such make-whole fundamental change or notice of redemption, as the case may be.
