Accounting Policies (Policies)	9 Months Ended
Sep. 30, 2022
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation: The condensed consolidated financial statements include the accounts of the company and its wholly owned subsidiaries and include all adjustments, which were of a normal recurring nature, necessary to present fairly the financial position of the company as of September 30, 2022 and the results of its operations and changes in its cash flow for the nine months ended September 30, 2022 and 2021, respectively. Certain foreign subsidiaries, represented by the European segment, are consolidated using an August 31 quarter end to meet filing deadlines. No material subsequent events have occurred related to the European segment, which would require disclosure or adjustment to the company's financial statements. All significant intercompany transactions are eliminated. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the full year.
Use of Estimates	Use of Estimates: The condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from these estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements (Already Adopted):
New Accounting Pronouncements, Not yet Adopted	In March 2020, the FASB issued ASU 2020-04 "Reference Rate Reform (Topic 848): Facilitation of Effects of Reference Rate Reform on Financial Reporting," which is intended to provide temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates if certain criteria are met. The guidance may be adopted in any period prior to the guidance expiration on December 31, 2022. The company adopted ASU 2020-04 effective January 1, 2022 and the adoption did not have a material impact on the company's financial statements. Interest arrangements previously referring to LIBOR prior to adoption, now refer to a secured overnight finance rate (SOFR).
