Income Tax Disclosure [Abstract]
Income Tax, Policy [Policy Text Block]	The provision or benefit for income taxes includes U.S. federal income taxes (determined on a consolidated return basis), foreign income taxes, and state income taxes. We participate in tax equity investments in renewable energy projects that qualify for federal investment tax credits. These investments are accounted for under the proportional amortization method. Tax credits and other related tax benefits are recognized as a reduction of income tax expense as they are realized, with corresponding amortization of the investment in proportion to the tax benefits received. During 2025, we recognized $5.3 million of investment tax credits and other tax benefits and recorded $5.2 million of amortization related to these investments. The tax credits and related amortization are presented net within the Provision for income taxes in the Consolidated Statement of Operations. As of December 31, 2025, the unamortized balance of renewable energy tax credit investments was $51.1 million, and unfunded commitments related to these investments totaled $40.8 million. These amounts are included in Deferred charges and other assets and Accounts payable and accrued liabilities, respectively, on the Consolidated Balance Sheet. Deferred taxes are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates.In assessing the usefulness of deferred tax assets, we consider whether it is more likely than not that some portion or all of the net deferred tax assets will not be realized. The future realization of net deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. During 2025, we recorded a net $3.9 million decrease in our valuation allowance primarily driven by utilization and expiration of state net operating losses, along with legislative changes in certain states. The valuation allowances can be affected in future periods by changes to tax laws, changes to statutory tax rates, and changes in estimates of future taxable income
