Senior Notes

In July 2021, the Company issued $575.0 million aggregate principal amount of 4.125% Senior Notes due July 15, 2029 in a private placement.

Interest on the Senior Notes is payable semi-annually in arrears on January 15 and July 15 of each year, commencing on January 15, 2022. The Company received net proceeds from the offering of the Senior Notes of $565.7 million after deducting underwriting commissions of $7.2 million and incurred additional issuance costs of $2.1 million. Total debt issuance costs of $9.3 million are being amortized to interest expense using the effective interest method over the term of the Senior Notes. The Company may redeem the Senior Notes, in whole or in part, at any time prior to July 15, 2024 at a price equal to 100% of the principal amount thereof plus a “make-whole” premium and accrued and unpaid interest, if any. The Company may at its election redeem all or a part of the Senior Notes on or after July 15, 2024, on any one or more occasions, at the redemption prices set forth in the indenture governing the Senior Notes (the “Indenture”), plus, in each case, accrued and unpaid interest thereon, if any, to, but excluding, the applicable redemption date. In addition, at any time prior to July 15, 2024, the Company may on any one or more occasions redeem up to 40% of the aggregate principal amount of the Senior Notes outstanding under the Indenture with the net cash proceeds of one or more equity offerings at a redemption price equal to 104.125% of the principal amount of the Senior Notes then outstanding, plus accrued and unpaid interest thereon, if any, to, but excluding, the applicable redemption date. The Company may also at its election redeem the Senior Notes in whole, but not in part, at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, if certain changes in tax law occur as set forth in the Indenture.

If the Company experiences a change of control triggering event (as defined in the Indenture), the Company must offer to repurchase the Senior Notes at a repurchase price equal to 101% of the principal amount of the Senior Notes to be repurchased, plus accrued and unpaid interest, if any, to the repurchase date.

The Indenture contains covenants limiting the Company’s ability and the ability of certain subsidiaries to create liens on certain assets to secure debt; grant a subsidiary guarantee of certain debt without also providing a guarantee of the Senior Notes; and consolidate or merge with or into, or sell or otherwise dispose of all or substantially all of its assets to, another person. These covenants are subject to a number of limitations and exceptions. Certain of these covenants will not apply during any period in which the Senior Notes are rated investment grade by Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services. As of April 30, 2023, the Company was in compliance with all of its covenants under the Indenture.
