Unsecured Credit Facility

On September 3, 2020, we entered into a $1.5 billion unsecured five-year Amended and Restated Credit Agreement that amended and restated our then-existing $1.5 billion unsecured revolving credit facility. On January 12, 2023, the agreement was further amended to change the reference rate from LIBOR to SOFR (as amended, the “Credit Agreement”). Following the amendment, borrowings under the Credit Agreement were available at variable rates based on SOFR plus 1.10% or the bank prime rate and we currently pay a commitment fee at an annual rate of 0.175% on the unused portion of the revolving credit facility. The applicable margins over SOFR and base rate borrowings, along with commitment fees, are subject to adjustment every quarter based on our leverage ratio, as defined in the Credit Agreement. All borrowings under the Credit Agreement may be prepaid without penalty.

As of December 31, 2022 and 2021, we had no outstanding borrowings on the revolving credit facility. As of December 31, 2022 and 2021, we had $7.7 million and $8.9 million, respectively, of letters of credit outstanding under the revolving credit facility.

Senior Unsecured Notes

On January 15, 2023, we redeemed the $500.0 million aggregate outstanding principal amount of our 4.50% senior notes due 2023 in full. We funded this redemption using cash on hand.

Under the indentures, the notes are senior unsecured obligations and rank equally in right of payment with all of our existing and future unsecured and unsubordinated obligations. If we experience a change in control accompanied by a downgrade in our credit rating, we will be required to make an offer to repurchase each series of the notes at a price equal to 101% of their principal amount plus accrued and unpaid interest.

Other Notes, Revolving Credit and Letters of Credit/Letters of Guarantee Facilities

A revolving credit facility with a credit limit of $7.8 million is in place for an operation in Asia with an outstanding balance of $2.2 million and $4.7 million as of December 31, 2022 and 2021, respectively.

Various industrial revenue bonds had combined outstanding balances of $7.4 million and $7.7 million as of December 31, 2022 and 2021, respectively, and have maturities through 2027.

A standby letters of credit/letters of guarantee agreement with one of the lenders under our Credit Agreement provides letters of credit and/or letters of guarantee in an amount not to exceed $50.0 million in the aggregate. As of December 31, 2022, a total of $18.7 million of letters of credit/guarantee were outstanding under this facility.

Covenants

The Credit Agreement and the Indentures include customary representations, warranties, covenants and events of default provisions. The covenants under the Credit Agreement include, among other things, two financial maintenance covenants that require us to comply with a minimum interest coverage ratio and a maximum leverage ratio. We were in compliance with all financial covenants in our Credit Agreement at December 31, 2022.
