On March 1, 2022, pursuant to a note purchase and master note agreement dated as of June 10, 2021 (the NYL note purchase agreement), the Company issued and sold $25,000,000 in aggregate principal amount of its 2.83% Senior Notes, Series 2022-A, due March 1, 2032 (the Series 2022-A Notes). In addition, on March 1, 2022, pursuant to a note purchase and private shelf agreement dated as of June 10, 2021 (the Prudential note purchase agreement), the Company issued and sold $50,000,000 in aggregate principal amount of its 2.83% Senior Notes, Series 2022-B, due March 1, 2032 (the Series 2022-B Notes). The Series 2022-A Notes and the Series 2022-B Notes bear interest at a fixed rate of 2.83%, with interest to be paid semi-annually and with equal annual principal payments beginning on March 1, 2026 and continuing through final maturity on March 1, 2032. The proceeds of the issuance of the Series 2022-A Notes and the Series 2022-B Notes are being used primarily for capital expenditures, to pay down existing debt and for other corporate purposes. The NYL note purchase agreement and the Prudential note purchase agreement require the maintenance of certain financial ratios and covenants that are substantially similar to the Company’s existing long-term debt and provide for customary events of default.

On June 24, 2022, the Company entered into a credit agreement with a syndicate of banks. The credit agreement provides for credit facilities in an initial aggregate principal amount of $450,000,000, consisting of (a) a $350,000,000 multi-currency revolving credit facility and (b) a $100,000,000 delayed draw term loan credit facility, each of which matures on June 24, 2027.

This credit agreement replaced the Company’s prior $350,000,000 revolving credit agreement. The Company maintains import letters of credit, and standby letters of credit under its workers’ compensation insurance agreements and for other purposes, as needed from time to time, which are issued under the revolving credit agreement. As of September 30, 2022, the Company had outstanding letters of credit totaling $6,772,000 and $155,000,000 of outstanding borrowings under the credit agreement, inclusive of a $100,000,000 delayed draw term loan. There was $288,228,000 available under the credit agreement as of September 30, 2022.

The Company’s loan agreements contain provisions which, among others, require maintenance of certain financial ratios and place limitations on additional debt, investments and payment of dividends. Based on the loan agreement provisions that place limitations on dividend payments, unrestricted retained earnings (i.e., retained earnings available for dividend distribution) were $223,686,000 and $468,095,000 at September 30, 2022 and December 31, 2021, respectively.
