Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Consolidation | Our consolidated financial statements provide an overall view of our results of operations, financial condition and cash flows. They include our accounts and the accounts of entities we control, including majority-owned domestic and foreign subsidiaries. They do not include our intercompany transactions and accounts, which are eliminated. Throughout these Notes to Consolidated Financial Statements, unless specified otherwise, references to “Weyerhaeuser,” “the company,” “we” and “our” refer to the consolidated company. The accompanying unaudited Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. Except as otherwise disclosed in these Notes to Consolidated Financial Statements, such adjustments are of a normal, recurring nature. The Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission pertaining to interim financial statements. Certain information and footnote disclosures normally included in our annual Consolidated Financial Statements have been condensed or omitted. These quarterly Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2024. Results of operations for interim periods should not necessarily be regarded as indicative of the results that may be expected for the full year.
Derivative Instruments | Derivative Instruments At times, we may manage exposure to certain risks by entering into derivative instruments. We do not enter into derivative instruments for speculative purposes. We record all derivative instruments on our Consolidated Balance Sheet at fair value. We are allowed to net settle transactions with respective counterparties for certain derivative instruments; however, we have not offset derivative asset and liability balances on our Consolidated Balance Sheet. For derivative instruments that are designated as hedging instruments in a qualifying cash flow hedge, the hedging instrument’s income or loss is reported as a component of other comprehensive income (loss) and recorded in accumulated other comprehensive loss on our Consolidated Balance Sheet. The income or loss is subsequently reclassified into net earnings when the hedged transaction affects net earnings in the same line item as the underlying hedged transaction in our Consolidated Statement of Operations. Where applicable, the initial value of hedged components excluded from the assessment of effectiveness are amortized over the life of the hedging instrument, using a systematic and rational method, and recognized in the same line item as the hedged transaction. Cash flows from derivative instruments designated as hedging instruments are classified in the same category as the cash flows from the respective hedged transaction. See Note 9: Fair Value of Financial Instruments.
Earnings Per Share | We use the treasury stock method to calculate the dilutive effect of our outstanding stock options, restricted stock units and performance share units.
