The Company mitigates its financing risk by using multiple financial institutions and only entering into credit arrangements with institutions with investment grade credit ratings. The Company monitors counterparty credit ratings on an ongoing basis.

The indenture under which the Company’s senior bonds were issued does not include financial covenants, but does limit the incurrence of certain liens and encumbrances as well as indebtedness by the Company’s subsidiaries in excess of certain amounts. The agreements under which the Company’s nonpublic debt was issued include two financial covenants: a consolidated cash flow/fixed charges ratio and a consolidated funded indebtedness/cash flow ratio, each as defined in the respective agreement. The Company was in compliance with these covenants as of December 31, 2023. These covenants have not restricted, and are not expected to restrict, the Company’s liquidity or capital resources.

All outstanding long-term debt has been issued by the Company and none has been issued by any of its subsidiaries. There are no guarantees of the Company’s long-term debt.
