Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the United States Securities and Exchange Commission (the "SEC"). These unaudited condensed consolidated financial statements omit certain notes and other financial information and therefore, should be read in conjunction with the 2025 Form 10-K. The Condensed Consolidated Balance Sheet information presented herein as of December 31, 2025 has been derived from the audited consolidated financial statements as of that date. For further information, refer to the consolidated financial statements and notes thereto included in the Company's Form 10-K for the year ended December 31, 2025. Due to the impact of weather activity and other macroeconomic uncertainties, the Company's operating results for the three months ended March 31, 2026 and financial position as of March 31, 2026 are not necessarily indicative of the results or financial position that may be expected for the year ending December 31, 2026 or for other future periods. The financial results from the Company's operations outside of the U.S., Canada, the Caribbean, and certain subsidiaries in the Philippines, are reported and consolidated on a two-month delayed basis (fiscal year-end of October 31) as permitted by GAAP in order to provide sufficient time for accumulation of their results.
Use of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. In the opinion of management, all adjustments (consisting only of normal recurring accruals and adjustments) considered necessary for a fair presentation have been included. There have been no material changes to our significant accounting policies and estimates from those disclosed in the Company's financial statements included in Form 10-K for the year ended December 31, 2025 other than as disclosed herein.
Consolidation, Variable Interest Entity, Policy	The Company consolidates the liabilities of its deferred compensation plan and the related assets, which are held in a rabbi trust and also considered a variable interest entity ("VIE") of the Company. The rabbi trust was created to fund the liabilities of the Company's deferred compensation plan. The Company is considered the primary beneficiary of the rabbi trust because the Company directs the activities of the trust and can use the assets of the trust to satisfy the liabilities of the Company's deferred compensation plan.
Consolidation Noncontrolling Interests	Noncontrolling interests represent the minority shareholders' share of the net income or loss and shareholders' investment in consolidated subsidiaries. Noncontrolling interests are presented as a component of shareholders' investment in the unaudited Condensed Consolidated Balance Sheets and reflect the initial fair value of these investments by noncontrolling shareholders, along with their proportionate share of the income or loss of the subsidiaries, less any dividends or distributions.
Earnings per Share	The Company computes earnings per share of its non-voting Class A Common Stock ("CRD-A") and voting Class B Common Stock ("CRD-B") using the two-class method, which allocates the undistributed earnings in each period to each class on a proportionate basis. The Company's Board of Directors has the right, but not the obligation, to declare higher dividends on the CRD-A shares than on the CRD-B shares, subject to certain limitations. In periods when the dividend is the same for CRD-A and CRD-B or when no dividends are declared or paid to either class, the two-class method generally will yield the same earnings per share for CRD-A and CRD-B. During 2026 and 2025, the Board of Directors has declared the same dividend on CRD-A and CRD-B.

Disclosure of accounting policy for the use of estimates in the preparation of financial statements in conformity with generally accepted accounting principles.
