Use of Estimates
The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions. These estimates and assumptions impact the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amounts of net earnings during the reporting periods. Actual results could be different from these estimates.
Cash, Cash Equivalents and Restricted Cash
Cash and cash equivalents include highly liquid investments with an original maturity of three months or less at the time of purchase. Cash and cash equivalents held at subsidiary facilities was $282 million and $194 million as of September 30, 2026 and December 31, 2025, respectively.
The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amounts shown in the consolidated statements of cash flows:

Recent Accounting Standards Not Yet Adopted
In May 2026, the FASB issued ASU 2026-02, Environmental Credits and Environmental Credit Obligations (Topic 818), which establishes guidance for the recognition, measurement, presentation and disclosure of environmental credits and environmental credit obligations. The guidance is effective for annual reporting periods beginning after December 15, 2027 and interim reporting periods within those annual periods. The amendment must be applied retrospectively through a cumulative-effect adjustment to the opening balance of retained earnings as of the beginning of the annual reporting period of adoption. Early adoption is permitted. As of September 30, 2026, the Company has not elected to early adopt the standard and is evaluating the effect of the new guidance on its consolidated financial statements.
