The Company’s share of earnings or losses from nonconsolidated affiliates is included in the condensed consolidated financial statements using the equity method of accounting when the Company is able to exercise significant influence over the operating and financial decisions of the affiliate.

Supply Chain Financing

As part of our strategy to manage working capital, we have entered into agreements with various financial institutions that act as intermediaries between the Company and certain suppliers. Liabilities associated with these arrangements are recorded in Accounts payable on the Consolidated Balance Sheets and amounted to $222.2 million, $215.7 million and $242.6 million at June 30, 2025, December 31, 2024 and June 30, 2024, respectively.

Non-Traded Investments

The Company has invested in U.S. affordable housing, historic renovation and other real estate investments (Non-Traded Investments) that have been identified as variable interest entities which qualify for certain tax credits and other tax benefits. Since the Company does not have the power to direct the day-to-day operations of the Non-Traded Investments and the risk of loss is limited to the amount of contributed capital, the Company is not considered the primary beneficiary. Therefore, in accordance with the Consolidation Topic of the Accounting Standards Codification (ASC), the Non-Traded Investments are not consolidated.
