BASIS OF PRESENTATION

We are a corporation that has elected to be taxed as a real estate investment trust (REIT). We expect to derive most of our REIT income from investments in timberlands, including the sale of standing timber. As a REIT, we generally are not subject to federal corporate level income taxes on REIT taxable income that is distributed to shareholders. We are required to pay corporate income taxes on earnings of our taxable REIT subsidiaries (TRSs), which includes our Wood Products segment and portions of our Timberlands and Real Estate, Energy and Natural Resources (Real Estate & ENR) segments.

Our consolidated financial statements provide an overall view of our results of operations and financial condition. They include our accounts and the accounts of entities we control, including:


•	majority-owned domestic and foreign subsidiaries and


•	variable interest entities in which we are the primary beneficiary.

They do not include our intercompany transactions and accounts, which are eliminated.

We account for investments in and advances to unconsolidated equity affiliates using the equity method, with taxes provided on undistributed earnings. This means that we record earnings and accrue taxes in the period earnings are recognized by our unconsolidated equity affiliates.

Throughout these Notes to Consolidated Financial Statements, unless specified otherwise, references to “Weyerhaeuser,” “we,” “the company” 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, 2017. Results of operations for interim periods should not necessarily be regarded as indicative of the results that may be expected for the full year.

NEW ACCOUNTING PRONOUNCEMENTS

Leases

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, which requires lessees to recognize assets and liabilities for the rights and obligations created by those leases and requires leases to be recognized on the balance sheet. The new guidance is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted. We plan to adopt on January 1, 2019. We have evaluated the relevant guidance and will continue to monitor subsequent revisions either made or being contemplated by the FASB, including application of the available practical expedients. We expect the adoption to result in the recognition of the present value of the future commitments on operating leases on our Consolidated Balance Sheet, which is primarily related to vehicles, equipment, office and wholesale leases previously disclosed in Note 14, “Legal Proceedings, Commitments and Contingencies,” in our Annual Report on Form 10-K for the year ended December 31, 2017.

Reclassification of Certain Amounts from Accumulated Other Comprehensive Loss

In February 2018, the FASB issued ASU 2018-02, which allows for the reclassification of certain income tax effects related to the Tax Cuts and Jobs Act (the "Tax Act") between “Accumulated other comprehensive loss” and “Retained earnings.” This ASU provides that adjustments to deferred tax liabilities and assets related to a change in tax laws be included in “Income from continuing operations”, even in situations where the related items were originally recognized in “Other comprehensive income.” The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. Adoption of this ASU is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the tax laws was recognized. We adopted this ASU during first quarter 2018 using the period of adoption method, which resulted in a reclassification of $253 million from "Accumulated other comprehensive loss" to "Retained earnings" on our Consolidated Balance Sheet due to changes in federal statutory and effective state rates. In general, tax effects unrelated to the Tax Cuts and Jobs Act are released from accumulated other comprehensive loss using the portfolio approach.

In January 2016, the FASB issued ASU 2016-01, which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. We adopted ASU 2016-01 in first quarter 2018, which resulted in a reclassification of accumulated unrealized gains on available-for-sale securities of $9 million from "Accumulated other comprehensive loss" to "Retained earnings" on our Consolidated Balance Sheet.
