NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
FOR THE QUARTERQUARTERS AND YEARS-TO-DATE ENDED MARCH 31,SEPTEMBER 30, 2018 AND 2017

NOTE 1: 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 expectplan to adopt on January 1, 2019. We are still evaluating certain aspects ofhave evaluated the revisedrelevant guidance and will continue to monitor subsequent revisions either made or being contemplated by the FASB, including application of the available practical expedients. We expectestimate the adoption towill result in the recognition of the present valueadditional rights of the future commitments onuse assets and lease liabilities for operating leases of less than 2 percent of our total assets on our Consolidated Balance Sheet. These leases are primarily related to vehicles, equipment, office and wholesale space 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 No. 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.


NOTE 2: BUSINESS SEGMENTS

Reportable business segments are determined based on the company’s "management approach," as defined by FASB ASC Topic 280, “Segment Reporting.” The management approach is based on the way the chief operating decision maker organizes the segments within a company for making decisions about resources to be allocated and assessing their performance.



We are principally engaged in growing and harvesting timber; manufacturing, distributing, and selling products made from trees; maximizing the value of every acre we own through the sale of higher and better use (HBU) properties; and monetizing reserves of minerals, oil, gas, coal, and other natural resources on our timberlands. The following is a brief description of each of our reportable business segments and activities:


Timberlands – which includes logs, timber and leased recreational access;
Real Estate & ENR – which includes sales of timberlands; rights to explore for and extract hard minerals, oil and gas production and coal; and equity interests in our Real Estate Development Ventures; and
Wood Products – which includes softwood lumber, engineered wood products, structural panels, medium density fiberboard and building materials distribution.

A reconciliation of our business segment information to the respective information in the Consolidated Statement of Operations is as follows:

(1)The Real Estate & ENR
Net contribution to earnings for the Timberlands segment includes the equity earnings from investments ina noncash pretax impairment charge of $147 million, recorded during second quarter 2017. This impairment was a result of our agreement to sell our Uruguayan operations, as announced during June 2017. Refer to Note 15: Charges for Integration and advances to our Real Estate Development Ventures, which are accounted for under the equity method.Restructuring, Closures and Asset Impairments.
(2)
Net contribution to earnings for the Wood Products segment includes a $25 million recovery and a $25 million charge recorded in the year-to-date period ended September 30, 2018, and $190 million and $240 million charges recorded in the quarter and year-to-date period ended September 30, 2017, respectively. We did not receive any insurance recoveries or record additional charges in third quarter 2018. These changes were recorded to accrue for estimated costs to remediate an issue with certain I-joists coated with our former Flak Jacket® Protection product. Refer to Note 16: Charges (Recoveries) for Product Remediation, Net for additional details.
(3)Unallocated items are gains or charges not related to, or allocated to, an individual operating segment. They include a portion of items such as: share-based compensation expenses, pension and postretirement costs, foreign exchange transaction gains and losses and the elimination of intersegment profit in inventory and LIFO.


NOTE 3: REVENUE RECOGNITION

A majority of our revenue is derived from sales of delivered logs and manufactured wood products. We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, which we adopted on January 1, 2018, using the cumulative effect method. The adoption of the new revenue recognition guidance did not materially impact our Consolidated Statement of Operations, Consolidated Balance Sheet, or Consolidated Statement of Cash Flows.



PERFORMANCE OBLIGATIONS

A performance obligation, as defined in ASC Topic 606, is a promise in a contract to transfer a distinct good or service to a customer. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue at the point in time, or over the period, in which the performance obligation is satisfied.

Performance obligations associated with delivered log sales are typically satisfied when the logs are delivered to our customers’ mills or delivered to an ocean vessel in the case of export sales. Performance obligations associated with the sale of wood products are typically satisfied when the products are shipped. The company has elected, as an accounting policy, to treat shipping and handling that is performed after a customer obtains control of the product as an activity required to fulfill the promise to transfer the good; therefore we will not evaluate this requirement as a separate performance obligation.

Customers are generally invoiced shortly after logs are delivered or after wood products are shipped, with payment generally due within a month or less of the invoice date. ASC Topic 606 requires entities to consider significant financing components of contracts with customers, though allows for the use of a practical expedient when the period between satisfaction of a


performance obligation and payment receipt is one year or less. Given the nature of our revenue transactions, we have elected to utilize this practical expedient.

Performance obligations associated with real estate sales are generally met when placed into escrow and all conditions of closing have been satisfied.

Substantially all of the company’s performance obligations are satisfied as of a point in time. Therefore, there is little judgment in determining when control transfers for our business segments as described above.

The transaction price for log sales generally equals the amount billed to our customer for logs delivered during the accounting period. For the limited number of log sales subject to a long-term supply agreement, the transaction price is variable but is known at the time of billing. For wood products sales, the transaction price is generally the amount billed to the customer for the products shipped but may be reduced slightly for estimated cash discounts and rebates.

There are no significant contract estimates related to the real estate business.

CONTRACT BALANCES

In general, customers are billed and a receivable is recorded as we ship and/or deliver wood products and logs. We generally receive payment shortly after products have been received by our customers. Contract asset and liability balances are immaterial.

For real estate sales, the company receives the entire consideration in cash at closing.

(2)
Other Timberlands sales include sales of seeds and seedlings, chips, as well as sales from our former Uruguayan operations (sold during third quarter 2017). Our former Uruguayan operations included logs, plywood and hardwood lumber harvested or produced. Refer to Note 4: Operations Divested for further information.




NOTE 4: OPERATIONS DIVESTED

On October 12, 2016, we announced the exploration of strategic alternatives for our Uruguay timberlands and manufacturing operations, which was part of our Timberlands business segment. On June 2, 2017, the Weyerhaeuser Board of Directors approved an equity purchase agreement with a consortium led by BTG Pactual's Timberland Investment Group (TIG), including other long-term investors, pursuant to which the Company agreed to sell, in exchange for $403 million in cash, all of its equity interest in the subsidiaries that collectively owned and operated its Uruguayan timberlands and manufacturing operations.

On September 1, 2017, we completed the sale of our Uruguay timberlands and manufacturing operations for approximately $403 million of cash proceeds. Due to the $147 million impairment of our Uruguayan operations recorded during second quarter 2017 (refer to Note 15: Charges for Integration and Restructuring, Closures and Asset Impairments), no material gain or loss was recorded as a result of this sale.



The sale of our Uruguayan operations was not considered a strategic shift that had or will have a major effect on our operations or financial results, and therefore did not meet the requirements for presentation as discontinued operations.


NOTE 5: NET EARNINGS PER SHARE AND SHARE REPURCHASES

Our basic and diluted earnings per share were:
$0.350.34 during firstthird quarter 2018 and $1.11 during year-to-date 2018;
$0.210.17 during firstthird quarter 2017 and $0.41 during year-to-date 2017.

Basic earnings per share is net earnings divided by the weighted average number of our outstanding common shares, including stock equivalent units where there is no circumstance under which those shares would not be issued. Diluted earnings per share is net earnings divided by the sum of the weighted average number of our outstanding common shares and the effect of our outstanding dilutive potential common shares:shares.

Share Repurchase Program

The 2016 Share Repurchase Authorization was approved and announced in November 2015 by our Board of Directors and authorized management to repurchase up to $2.5 billion of outstanding shares. We repurchased 8,583,244 common shares for $290 million (including transaction fees) during third quarter 2018 and 8,585,844 shares for $291 million (including transaction fees) during year-to-date 2018, under the 2016 Share Repurchase Authorization. Transaction fees incurred for repurchases are not counted as use of funds authorized for repurchase under the 2016 Share Repurchase Authorization. All common share purchases under the share repurchase program are to be made in open-market transactions. As of September 30, 2018, we had remaining authorization of $210 million for future share repurchases.

We record share repurchases upon trade date as opposed to the settlement date when cash is disbursed. We record a liability for repurchases that have not yet been settled as of period end. There were $18 million of unsettled repurchases as of September 30, 2018 and no unsettled repurchases as of December 31, 2017.

foreign inventories. If we used FIFO for all LIFO inventories, our stated inventories would have been higher by $70$69 million as of March 31,September 30, 2018, and $70 million as of December 31, 2017.


NOTE 7: SPECIAL-PURPOSE ENTITIES

From 2002 through 2004, we sold certain nonstrategic timberlands in five separate transactions. We are the primary beneficiary and consolidate the assets and liabilities of certain monetization and buyer-sponsored Special-purpose entities (SPEs) involved in these transactions. We have an equity interest in the monetization SPEs, but no ownership interest in the buyer-sponsored SPEs. The long-term notes of our monetization SPEs and the financial investments of our buyer-sponsored SPEs include $209 million and $253$302 million scheduled to mature in fourth quarter 2018 and third quarter of 2019, respectively. The financial investments of our buyer sponsored SPEs include $253 million scheduled to mature first quarter 2019, respectively.2019. We have classified the long-term notes scheduled to mature in fourth quarter 2018 and third quarter 2019 as current liabilities and the financial investments scheduled to mature in first quarter 2019 as current receivables on our Consolidated Balance Sheet.

FAIR VALUE OF PENSION PLAN ASSETS AND OBLIGATIONS

We estimate the fair value of pension plan assets based upon the information available during the year-endyear end reporting process. In some cases, primarily private equity funds, the information available consists of net asset values as of an interim date, cash flows between the interim date and the end of the year and market events. We update the year-endyear end estimated fair value of pension plan assets to incorporate year-endyear end net asset values reflected in financial statements received after we have filed our Annual Report on Form 10-K. During second quarter 2018, we recorded an increase in the beginning of year fair value of the pension assets of $44 million, or less than 1 percent.

During second quarter 2018, we also updated our mortality assumption and census data used to estimate our projected benefit obligation for our U.S. qualified pension plan. We recorded an adjustment to our projected benefit obligation, incorporating updated census data and applying new company-specific mortality data. As a result of these updates, the beginning of year pension projected benefit obligation decreased by $155 million, or approximately 2 percent. The net effect of these updates, including the update to the pension assets, was a $199 million improvement in funded status.

ACTIONS TO REDUCE PENSION PLAN OBLIGATIONS

On August 23, 2018, we announced actions intended to reduce the liabilities of our U.S. qualified pension plan while maintaining the plan's current funded status. We offered certain U.S. terminated vested plan participants the opportunity to elect an immediate lump sum distribution of their pension benefits. Based on qualifying participant elections received by the company, we expect to make distributions from plan assets to those who elect to receive a lump sum in fourth quarter 2018. We also intend to transfer a portion of U.S. qualified pension plan liabilities to an insurance company through the purchase of a group annuity contract. This transaction would also be funded with the pension plan assets and is expected to close in 2019. We expect to completerecord one-time noncash settlement charges for the valuationlump sum offer and the annuity purchase upon the respective completion dates, with the amounts of oureach charge to be determined at that time.

To maintain the U.S. qualified pension plan's current funded status in connection with these transactions, we contributed $300 million to the plan during third quarter 2018. Refer to Note 18: Income Taxes for details on the tax effects of this transaction.

Additionally, Weyerhaeuser’s pension plan assets duringare in the second quarter 2018.process of being transitioned to an allocation that will more closely match the plan’s liability profile going forward.

EXPECTED CONTRIBUTIONSFUNDING AND BENEFIT PAYMENTS

In 2018, we expect to:
be required to contribute approximately $23$24 million for our Canadian registered plan;
be required to contribute or make benefit payments for our Canadian nonregistered plans of $4$2 million;


make benefit payments of $19 million for our U.S. nonqualified pension plans; and
make benefit payments of $19 million for our U.S. and Canadian other postretirement plans.

We do not anticipate being required to make a contributionexpect any contributions to our U.S. qualified pension plansplan in 2018.2018 in addition to the $300 million contribution referenced above.

NOTE 10: LONG-TERM DEBT AND LINES OF CREDIT

During first quarter 2018, we paid our $62 million 7.00 percent debenture at maturity.

This replaced a $1.0 billion senior unsecured revolving credit facility that was set to expire September 2018.facility. The entire amount is available to Weyerhaeuser Company. Interest on borrowings are at LIBOR plus a spread or at other interest rates mutually agreed upon between the borrower and the lending banks. As of March 31,September 30, 2018, there were no borrowings outstanding.

(1)Excludes nonrecourse debt held by our Variable Interest Entities (VIEs).

To estimate the fair value of fixed rate long-term debt, we used the following valuation approaches:
market approach – based on quoted market prices we received for the same types and issues of our debt; or
income approach – based on the discounted value of the future cash flows using market yields for the same type and comparable issues of debt.

We believe that our variable rate long-term debt instruments have net carrying values that approximate their fair values with only insignificant differences.

The inputs to these valuations are based on market data obtained from independent sources or information derived principally from observable market data. The difference between the fair value and the carrying value represents the theoretical net premium or discount we would pay or receive to retire all debt at the measurement date.

FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS

We believe that our other financial instruments, including cash and cash equivalents, short-term investments, mutual fund investments held in grantor trusts, receivables, and payables, have net carrying values that approximate their fair values with only insignificant differences. This is primarily due to the short-term nature of these instruments and the allowance for doubtful accounts.




NOTE 12: LEGAL PROCEEDINGS, COMMITMENTS AND CONTINGENCIES

LEGAL PROCEEDINGS

We are party to various legal proceedings arising in the ordinary course of business. We are not currently a party to any legal proceeding that management believes could have a material adverse effect on our Consolidated Balance Sheet, Consolidated Statement of Operations, or Consolidated Statement of Cash Flows. See Note 18: Income Taxes for a discussion of a tax proceeding involving Plum Creek's 2008 U.S. federal income tax return.

ENVIRONMENTAL MATTERS

Site Remediation

Under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) – commonly known as the Superfund – and similar state laws, we:
are a party to various proceedings related to the cleanup of hazardous waste sites and
have been notified that we may be a potentially responsible party related to the cleanup of other hazardous waste sites for which proceedings have not yet been initiated.

We have received notification from the Environmental Protection Agency (the EPA) and have acknowledged that we are a potentially responsible party in a portion of the Kalamazoo River Superfund site in southwest Michigan. Our involvement in the remediation site is based on our former ownership of the Plainwell, Michigan mill located within the remediation site. Several other companies also have been deemed potentially responsible parties as past or present owners or operators of facilities within the site, or as arrangers under CERCLA.

We are currently cooperatingcooperated with other parties to jointly implement an administrative order issued by the EPA on April 14, 2016, with respect to a
portion of the site comprising a stretch of the river approximately 1.7 miles long referred to as the Otsego Township Dam Area. We do not expect to incur material losses related to theDuring third quarter 2018, implementation of this administrative order.order was completed.

In 2010, the company, along with others, was named as a defendant by Georgia-Pacific Consumer Products LP, Fort James Corporation and Georgia-Pacific LLC in an action seeking contribution under CERCLA for remediation costs relating to a certain area within the site. On March 29, 2018, the U.S. District Court issued an opinion and order assigning the company responsibility for five5 percent of approximately $50 million in past costs incurred by the plaintiffs. The remaining ninety-five95 percent of this pool of past costs incurred was allocated to the plaintiffs and other defendants.

The opinion and order does not establish allocation for future remediation costs, and accordingly, we may incur additional costs in connection with future remediation tasks for other areas of the site. In connection with the opinion and order, we have updated our assessmentbest estimate of the company’s reasonably possible estimated liability associated with the site and have recorded a pretax charge of $28 million in the first quarter as "Other operating costs (income), net" on the Consolidated Statement of Operations.

As of March 31,September 30, 2018, our total accrual for future estimated remediation costs on the active Superfund sites and other sites for which we are potentially responsible was approximately $72$67 million. These amounts are recorded in "Accrued liabilities" and "Other liabilities" on our Consolidated Balance Sheet.

Asset Retirement Obligations

We have obligations associated with the future retirement of tangible long-lived assets consisting primarily of reforestation obligations related to forest management licenses in Canada and obligations to close and cap landfills. As of March 31,September 30, 2018, our accrued balance for these obligations was $34$30 million. These obligations are recorded in "Accrued liabilities" and "Other liabilities" on our Consolidated Balance Sheet. The accruals haveaccrued balance has not changed materiallysignificantly since the end ofDecember 31, 2017.

Some of our sites have materials containing asbestos. We have met our current legal obligation to identify and manage these materials. In situations where we cannot reasonably determine when materials containing asbestos might be removed from the sites, we have not recorded an accrual because the fair value of the obligation cannot be reasonably estimated.

PRODUCT REMEDIATION

In July 2017, the company announced it was implementing a solution to address concerns regarding our TJI® Joists with Flak Jacket® Protection product. The company has determined that an odor in certain newly constructed homes is related to a recent formula change to the Flak Jacket coating that included a formaldehyde-based resin. This issue is isolated to Flak Jacket product manufactured after December 1, 2016, and does not affect any of the company’s other products. We recorded pretax charges of $290 million to accrue for remediation costs in the year-to-date period ended December 31, 2017. We received insurance recoveries of $20 million during the quarter ended March 31, 2018. Refer to Note 16: Charges (Recoveries) for Product Remediation, Net for further information.

IMPAIRMENTS OF LONG-LIVED ASSETS

In second quarter 2017, we recognized an impairment charge to the timberlands and manufacturing assets of our Uruguayan operations. On June 2, 2017, our Board of Directors approved an agreement to sell all of the Company's equity in the Uruguayan business to a consortium led by BTG Pactual's Timberland Investment Group (TIG). As a result of this agreement, the related assets met the criteria to be classified as held for sale. This designation required us to record the related assets at fair value, less an amount of estimated selling costs, and thus recognize a $147 million noncash pretax impairment charge. This amount was recorded in the Timberlands segment. The fair value of the related assets was primarily based on the agreed upon cash purchase price of $403 million. On September 1, 2017, we announced the completion of the sale. Refer to Note 4: Operations Divested for further details of the Uruguayan operations sale.

Additionally, in September 2017, we recognized an impairment charge of $6 million related to a non-strategic asset in our Wood Products segment. The fair value of the asset was determined using a contract value associated with the asset sale.



NOTE 16: CHARGES (RECOVERIES) FOR PRODUCT REMEDIATION, NET

In July 2017, we announced we were implementing a solution to address concerns regarding our TJI® Joists coated with our former Flak Jacket® Protection product. This issue was isolated to Flak Jacket product manufactured after December 1, 2016, and doesdid not affect any of our other products. We estimate that approximately 2,400 homes were affected.

We recorded pretax charges of $290 million in the year-to-date period ended December 31, 2017, to accrue for expected costs associated with the remediation. DuringIn first quarter 2018, we received and recorded insurance recoveries of $20 million. During second quarter 2018, we recorded an additional charge of $25 million as a result of additional product remediation expenses, partially offset by $5 million of insurance recoveries. We did not receive any insurance recoveries or record additional charges in third quarter 2018. During the quarter and year-to-date period ended September 30, 2017, we recorded $190 million and $240 million of product remediation charges, respectively. The charges and recoveries are attributable to our Wood Products segment and were recorded in "Charges (recoveries) for product remediation," net" on the Consolidated Statement of Operations.

As of March 31, 2018, $247 million has been paid out in relation to our remediation efforts. The remaining accrual of $43 million is recorded in "Accrued liabilities" on the Consolidated Balance SheetOperations. The company ultimately expects a significant portion of the total expense will be covered by insurance. As of March 31, 2018, $20 million has been received and recorded for insurance recoveries.

NOTE 18: INCOME TAXES
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 wholly-owned TRSs, which includes our Wood Products segment and portions of our Timberlands and Real Estate & ENR segments' earnings.



The quarterly provision for income taxes is based on the current estimate of the annual effective tax rate. Our 2018 estimated annual effective tax rate for our TRSs is approximately 2425 percent, which is higher than the U.S. domestic statutory federal tax rate primarily due to state income taxes and higher foreign tax rates applicable to foreign earnings and state income taxes.earnings.

TAX LEGISLATION

On December 22, 2017, H.R. 1, commonly known as the Tax Cuts and Jobs Act (the "Tax Act"), was enacted. The Tax Act contains significant changes to corporate taxation, including the reduction of the corporate tax rate from 35 percent to 21 percent. As a result of the reduction in the corporate tax rate, we revalued our deferred tax assets and liabilities and recorded a tax expense of $74 million during 2017, which reduced our net deferred tax asset. The deemedWe were not required to pay a repatriation on deferred foreign income provisions does not impact our operationstax due to the fact that we havehad no foreign undistributed earnings.

The impact of the Tax Act provisions effective in 2018 is a reduction to our overall estimated annual effective tax rate primarily due to the reduced corporate tax rate.

During first quarter 2018, we adopted ASU 2018-02 which allowsallowed for the reclassification of certain income tax effects related to the Tax Act between accumulated other comprehensive income and retained earnings. Refer to Note 1: Basis of Presentation for further details on this ASU and the related impact on our financial statements.

PENSION CONTRIBUTION TAX ADJUSTMENT

At the end of 2017, we revalued our deferred tax assets (including pension) to the 2018 federal tax rate of 21 percent, as a result of the Tax Act, as discussed above. During third quarter 2018, we announced actions intended to reduce the liabilities of our U.S. qualified pension plan while maintaining the plan’s current funded status and made a decision to contribute $300 million to our U.S. qualified pension plan (refer to Note 8: Pension and Other Postretirement Benefit Plans). We were able to deduct this contribution on our 2017 federal tax return at the 2017 federal tax rate of 35 percent. This resulted in an incremental $41 million tax benefit, for the portion attributable to our TRSs, during third quarter 2018.

ONGOING IRS MATTER
In connection with the merger with Plum Creek, we acquired equity interests in Southern Diversified Timber, LLC, a timberland joint venture (Timberland Venture) with an affiliate of Campbell Global LLC (TCG Member). On August 31, 2016, the Timberland Venture redeemed TCG Member's interest and became a fully consolidated, wholly-owned subsidiary of Weyerhaeuser.

We received a Notice of Final Partnership Administrative Adjustment (FPAA), dated July 20, 2016, from the Internal Revenue Service (IRS) in regard to Plum Creek's 2008 U.S. federal income tax treatment of the transaction forming the Timberland Venture. The IRS is asserting that the transfer of the timberlands to the Timberland Venture was a taxable transaction to Plum Creek at the time of the transfer rather than a nontaxable capital contribution. We have filed a petition in the U.S. Tax Court and will vigorously contest this adjustment.

In the event that we are unsuccessful in this tax litigation, we could be required to recognize and distribute gain to shareholders of approximately $600 million and pay built-in gains tax of approximately $100 million. We would also be required to pay interest on both of those amounts, which would be substantial. As much as 80 percent of any such gain distribution could be made with our common stock, and shareholders would be subject to tax on the distribution at the applicable capital gains tax rate. Alternatively, we could elect to retain the gain and pay corporate-level tax to minimize interest costs to the company.

Although the outcome of this process cannot be predicted with certainty, we are confident in our position based on U.S. tax law and believe we will be successful in defending it. Accordingly, no reserve has been recorded related to this matter.

RESULTS OF OPERATIONS

In reviewing our results of operations, it is important to understand these terms:

Sales realizations for Timberlands and Wood Products refer to net selling prices – thisprices. This includes selling price plus freight, minus normal sales deductions. Real Estate transactions are presented at the contract sales price before commissions and closing costs, net of any credits.
Net contribution to earnings does not include interest expense and income taxes.

In the following discussion, unless otherwise noted, references to increases or decreases in income and expense items, sales realizations, shipment volumes, and net contributions to earnings are based on the quarter ended March 31, 2018, compared to quarter ended March 31, 2017.


ECONOMIC AND MARKET CONDITIONS AFFECTING OUR OPERATIONS

The demand for logs within our Timberlands segment is directly affected by production levels of domestic wood-based building products. The strength of the U.S. housing market strongly affects demand in our Wood Products segment, as does repair and remodeling activity. Our Timberlands segment, specifically the Western region, is also affected by export demand.demand and trade policy. Japanese housing starts are a key driver of export log demand in Japan.
In firstthird quarter 2018, housing starts averaged 1.321.22 million total units on a seasonally adjusted annual basis according to the U.S. Census Bureau. This was 3 percent below second quarter 2018 which averaged 1.26 million starts on a seasonally adjusted annual basis. Single family units averaged 870 thousand units in the quarter and accounted for 6771 percent of total housing starts, up from 67 percent in first quarter. Multifamily starts reboundedquarter 2018 and unchanged from the decline posted in 2017.second quarter 2018. Single family starts year-to-date average from third quarter 2017 to third quarter 2018 increased by 3 percent. Multifamily starts were at 347 thousand, which were 5 percent lower than second quarter 2018, and are 6up 7 percent higher on a year ago basis for the quarter.compared to third quarter in 2017. We continue to expect improving U.S. housing starts and anticipate a level of approximately 1.301.28 million units in 2018, an 8 percent increase compared to 2017.2018. We attribute this continued improvement primarily to employment growth, improving consumer confidence and favorable mortgage rates which, while rising, remain nearaffordable on a historic lows.basis.
According to the Joint Center for Housing of Harvard University, the Leading Indicator of Remodeling Activity (LIRA) increased by 6.47.5 percent on a four quarter moving average basis in 2017third quarter 2018, and is expected to average 7.5increase to 7.7 percent year over year foron the same basis in fourth quarter 2018.
In U.S. wood product markets, advancedprices retreated in third quarter 2018 from peak levels posted in second quarter 2018, as supply issues related to transportation eased and producers maximized output. Demand growth slowed, consistent with performance in the first quarter of 2018, consistent with growth in homebuilding and remodeling segments,segment, as described above. According to Forest Economic Advisors, LLC, North American lumber consumption is expected to grow at a 4 percent rate in 2018. Consistent with this expectation, demand for logs increasedLog markets were consistent with wood products production within our Western region. This coupled with highermanufacturing, exhibiting slower demand, resulting in weaker market prices for western logs in the firstthird quarter drove higher realizations.2018. In the South,south, log supplies kept pace with increased demand, leaving prices flat to slightly increased from fourthsecond quarter 2017.2018.
Log inventories in Chinese ports increased 3.7 percent in the latter part of firstthird quarter 2018 as reported by International Wood Markets China Bulletin. The increased inventory level is attributedBulletin, which also reported continued good demand for construction lumber from imported logs. Volumes of U.S. log imports for the 8 months year to a slow start to the construction season due to the later occurrence of the Spring Festival and is expected to normalize over upcoming quarters.date are up 15 percent from 2017. In Japan, wooden housing starts for January and February areAugust 2018 were down 1.73.5 percent from August 2017 while the same period last year.key Post and Beam segment was 1.3 percent lower in August 2018 compared to August 2017.
We expect demand from China and Japan in 2018 to be similar to demand experienced in 2017.
Our Real Estate Energy and Natural Resources& ENR segment is affected by the health of the U.S. economy and especially the U.S. housing sector of the economy. According to the Realtors Land Institute (RLI) of the National Association of Realtors, the dollar volume of rural properties, including timber, sold in 2017 grew 4 percent over 2016 salesin 2017, while per acre prices were up 3 percent on average. Additionally, RLI is optimistic thatexpects these trends willto continue in 2018.

Real Estate & ENR sales to unaffiliated customers increased $14 million – 17 percent – primarily due to increased acres sold.



These increases were offset by a $23 million – 5 percent – decrease in Timberlands sales to unaffiliated customers, increased $19 million – 4 percent – primarily attributable to increased Western log sales realizations, partially offset by decreased international operations revenue from the saledivestiture of our Uruguayan operations in third quarter 2017.

Costs of products sold

Costs of products sold increased $76$78 million – 6 percent – primarily attributable to the following:
Wood Products segment costs of products sold increased $79$66 million – 7 percent – primarily due to increased log and fiber costs across all product lines in the West and Canada; and
Real Estate & ENR segment costs of products sold increased $23 million – 74 percent – primarily due to increased acres sold and higher per acre basis of real estate sold.

These increases were partially offset by a $12 million decrease in Timberlands segment costs of products sold, primarily attributable to the divestiture of our Uruguayan operations in third quarter 2017.

Operating income

Operating income increased $132 million – 64 percent – primarily attributable to:
decreased charges of $190 million for product remediation (refer to Note 16: Charges (Recoveries) for Product Remediation, Net); and

These increases to operating income were partially offset by the following:

decreased consolidated gross margin of $40 million, as described above; and
increased expenses of $33 million in other operating income (costs) comprised of many smaller fluctuations such as a $5 million increase in foreign exchange losses.

Net earnings

Net earnings increased $125 million – 96 percent. This was partially attributable to:
increased operating income of $132 million, as described above; and
decreased interest expense of $5 million (refer to Interest Expense).

Real Estate & ENR sales to unaffiliated customers increased $24 million – 13 percent – primarily attributable to increased acres sold; and
Timberlands sales to unaffiliated customers increased $9 million – 1 percent – primarily due to increased Western log sales realizations, offset by decreased revenue resulting from the divestiture of our Uruguayan operations in third quarter 2017.

Costs of products sold

Costs of products sold increased $265 million – 7 percent – primarily attributable to the following:
Wood Products segment costs of products sold increased $262 million – 9 percent – primarily due to increased log and fiber costs across all product lines in the West and Canada;
Real Estate & ENR segment costs of products sold increased $36 million – 54 percent – primarily attributable to an increase in acres sold;
Unallocated costs of products sold increased $19 million – 95 percent – primarily due to an increase in LIFO and intercompany profit elimination; and
Timberlands segment costs of products sold increased $4 million – less than 1 percent – primarily due to increased external sourcing costs in Canada and the West, offset by a decrease in costs of products sold from the divestiture of our Uruguayan operations in third quarter 2017.

These increases were partially offset by the elimination of costs of products sold associated with internal sales.

Operating income

Operating income increased $562 million – 86 percent – primarily attributable to:
a $240 million decrease in charges for product remediation (refer to Note 16: Charges (Recoveries) for Product Remediation, Net for further details);
an increased consolidated gross margin of $202 million, as described above; and
Unallocated costsa decrease in a noncash pretax impairment charge of product sold increased $18 million – 14 percent – primarily due$147 million.

Includes logs, plywood and hardwood lumber harvested or produced by our former international operations in Uruguay. On June 2nd, 2017, we agreed to sell all of our equity interest in the subsidiaries that collectively own and operate our Uruguayan timberlands and manufacturing operations and recorded a $147 million impairment in operating income within the Timberlands business segment during second quarter 2017. Our Uruguayan operations were divested on September 1, 2017. Refer to Note 4: Operations Divested and Note 15: Charges for Integration and Restructuring, Closures and Asset Impairments for further information.

Comparing FirstThird Quarter 2018 with FirstThird Quarter 2017

Net sales to unaffiliated customers

Net sales to unaffiliated customers decreased $23 million – 5 percent – primarily due to decreased revenue resulting from the sale of our Uruguayan operations in third quarter 2017.
Intersegment sales

Intersegment sales increased $19$6 million – 3 percent – primarily due to increases in Western log prices.



Costs of products sold

Costs of products sold decreased $12 million – 2 percent – primarily due to the following:

a $21 million decrease in costs of products sold resulting from the sale of our Uruguayan operations in third quarter 2017; and
a $17 million decrease in costs of products sold resulting from the termination of our management agreement for the Twin Creeks Venture in fourth quarter 2017.

These decreases in costs of products sold were partially offset by a $20 million increase primarily due to higher external sourcing costs in the West.

Operating income and Net contribution to earnings

Operating income and Net contribution to earnings decreased $5 million – 4 percent – primarily attributable to the changes in net sales and costs of products sold as explained above.

Comparing Year-to-Date 2018 with Year-to-Date 2017

Net sales to unaffiliated customers

Net sales to unaffiliated customers increased $9 million – 1 percent – primarily due to to:
a $41$93 million increase in Western log sales attributable to a 26%20 percent increase in Western log prices, partially offset by a 6%5 percent decrease in Western delivered logslog sales volumes.
This increase was partially offset by the following:
a $19$63 million decrease in salesrevenue from our UruguayUruguayan operations, which were divested in third quarter 2017.2017;
an $18 million decrease in Other delivered log sales primarily resulting from the termination of our management agreement for the Twin Creeks Venture in fourth quarter 2017; and
a $13 million decrease in Stumpage and pay-as-cut timber sales.

Intersegment sales

Intersegment sales increased $26$54 million – 1310 percent – primarily due to increases in Western and Canada log prices, consistent with third party sales discussed above.

Costs of products sold

Costs of products sold increased $7$4 million – less than 1 percent – primarily due to:
a $72 million increase in costs of products sold primarily attributable to increased external sourcing costs to meetin the West as a result of increased demand for export sales. Thelog prices;
a $20 million increase was partially offset by a decrease in our international costcosts of products sold in Canada, primarily due to a 5 percent increase in sales volume and increased sourcing costs; and
a $19 million increase in costs of products sold in the divestitureSouth, primarily due to a 4 percent increase in log sales volumes.

These increases were partially offset by:

a $70 million decrease in costs of products sold from our Uruguayan operations, which were divested in third quarter 2017; and
a $40 million decrease in costs of products sold resulting from the termination of our management agreement for the Twin Creeks Venture in fourth quarter 2017.

Operating income and Net contribution to earnings

Operating income and Net contribution to earnings increased $41$209 million – 2878 percent – primarily attributable to:

a decrease in a noncash pretax impairment charge of $147 million. This impairment was a result of our agreement to sell our Uruguayan operations, as announced during June 2017 (refer to Note 15: Charges for Integration, Restructuring, Closures and Asset Impairments); and
increased gross margin of $59 million, as discussed above.

The timing of real estate sales is a function of many factors, including the general state of the economy, demand in local real estate markets, the ability to obtain entitlements, the ability of buyers to obtain financing, the number of competing properties listed for sale, the seasonal nature of sales (particularly in the northern states), the plans of adjacent landowners, our expectation of future price appreciation, the timing of harvesting activities, and the availability of government and not-for-profit funding. In any period the average sales price per acre will vary based on the location and physical characteristics of parcels sold.

Comparing FirstThird Quarter 2018 with FirstThird Quarter 2017

ChangesThe $25 million decrease in Net contribution to earnings from Unallocated Items werewas due to:
a $12 million increase in legal and environmental charges;
a$5 million increase in net foreign exchange losses; and
a$3 million increase in charges for elimination of intersegment profit in inventory and LIFO due to increased lumber and log inventory quantities.

Comparing Year-to-Date 2018 with Year-to-Date 2017

The $59 million decrease in Net contribution to earnings from Unallocated Items was primarily related to:
a $28$28 million increase in charges for "Other," due to environmental remediation charges recorded induring first quarter 2018 for environmental remediation (refer to Note 12: Legal Proceedings, Commitments and Contingencies);
a $15$30 million change in legal charges, primarily related to insurance recoveries received during year-to-date 2017, which resulted in a net credit of $20 million. No similar recoveries have been received during year-to-date 2018;
a$12 million increase in charges for "Eliminationelimination of intersegment profit in inventory and LIFO"LIFO due to an increase in intercompanyto increased lumber and log inventories from first quarter 2017 to first quarter 2018;inventory quantities; and
a $12an $8 million decrease inof increased charges relatedfor non-operating pension and other postretirement benefit costs primarily due to our merger with Plum Creek compared to first quarter 2017decreased expected return on plan assets (refer to Note 8: Pension and Other Postretirement Benefit Plans).

These increased charges were partially offset by $20 million decreased charges related to our merger with Plum Creek (refer toNote 15: Charges for Integration and Restructuring, Closures and Asset Impairments for further details).


INTEREST EXPENSE

Our interest expense, net of capitalized interest incurred, was:
$93 million for the firstthird quarter 2018 and $278 million year-to-date 2018; and
$9998 million for the firstthird quarter 2017 and $297 million year-to-date 2017.

Interest expense decreased by $6$5 million compared to third quarter 2017 and $19 million compared to year-to-date 2017 primarily due to a decrease in the decreased average outstanding debt balance in first quarter 2018 compared to first quarter 2017.




INCOME TAXES

Our provision for income taxes was:
$3015 million benefit for the firstthird quarter 2018 and $80 million expense year-to-date 2018; and
$2427 million benefit for the firstthird quarter 2017 and $31 million expense year-to-date 2017.

Our provision for income taxes is primarily driven by earnings generated by our TRSs. At the end of 2017, we revalued our deferred tax assets (including pension) to the 2018 federal tax rate of 21 percent, as a result of the Tax Act. During third quarter 2018, we announced actions intended to reduce the liabilities of our U.S. qualified pension plan while maintaining the plan’s current funded status and made a decision to contribute $300 million to our U.S. qualified pension plan (refer to Note 8: Pension and Other Postretirement Benefit Plans). We were able to deduct this contribution on our 2017 federal tax return at the 2017 federal tax rate of 35 percent. This resulted in an incremental $41 million tax benefit, for the portion attributable to our TRSs, during third quarter 2018. In third quarter 2017, we recognized a tax benefit related to charges for product remediation. Overall performance results for our business segments can be found in Consolidated Results.

The Tax Act, enacted in December 2017, reduced the U.S. corporate tax rate from 35 percent to 21 percent. In first quarter 2018, our provision for income taxes was higher compared to first quarter 2017 due to increased earnings in our TRS. The tax impact of the increased earnings more than offset the benefit of the reduced U.S. corporate tax rate.



LIQUIDITY AND CAPITAL RESOURCES

We are committed to maintaining an appropriate capital structure that enables us to protect the interests of our shareholders and lenders and maintain access to all major financial markets.

CASH FROM OPERATIONS



Consolidated net cash fromprovided by our operations was:
$136820 million for first quarteryear-to-date 2018; and
$35847 million for first quarteryear-to-date 2017.

Comparing first quarter 2018 with first quarter 2017

Net cash from operations increased $101decreased $27 million, primarily due to:our $300 million contribution to our U.S. qualified pension plan in third quarter 2018 (refer to Note 8: Pension and Other Postretirement Benefit Plansfor further details). This cash outflow was offset in part by:
increased cash flows generated from our business segments,businesses, excluding working capital changes, of $103$212 million;
decreaseda decrease in cash paid for income taxes of $42 million;
product remediation insurance recoveries received of $20 million in first quarter 2018;
decreased working capital used for accrued wages, salaries, and severance pay of $17$49 million; and
decreaseda decrease in cash paid for interest of $15 million; and

These increases were partially offset by a net increase in working capital from our business segments of $126$30 million.

CASH FROM (USED IN) INVESTING ACTIVITIES

Consolidated net cash used in and provided by investing activities was:
$76264 million used in investing activities for first quarteryear-to-date 2018; and
$68192 million provided by investing activities for first quarteryear-to-date 2017.

Comparing first quarter 2018 with first quarter 2017

Net cash used in investing activities increased $8$456 million, primarily due to:
a $6$421 million decrease in proceeds received from the sale of non-strategic assets;assets and operations, which is primarily due to $403 million in proceeds received from the sale of our Uruguay operations in third quarter 2017; and
a $6net $24 million increase in cash used for capital expenditures.

PERFORMANCE MEASURES

We use Adjusted Earnings before Interest, Taxes, Depreciation, Depletion and Amortization (Adjusted EBITDA) as a key performance measure to evaluate the performance of the consolidated company and our business segments. This measure should not be considered in isolation from and is not intended to represent an alternative to our results reported in accordance with U.S. generally accepted accounting principles (U.S. GAAP). However, we believe Adjusted EBITDA provides meaningful supplemental information for investors about our operating performance, better facilitates period to period comparisons, and is widely used by analysts, lenders, rating agencies and other interested parties.

Our definition of Adjusted EBITDA may be different from similarly titled measures reported by other companies. Adjusted EBITDA, as we define it, is operating income adjusted for depreciation, depletion, amortization, basis of real estate sold, unallocated pension service costs and special items. Adjusted EBITDA excludes results from joint ventures.

CRITICAL ACCOUNTING POLICIES

There have been no significant changes during firstthird quarter 2018 to our critical accounting policies presented in our 2017 Annual Report on Form 10-K.



QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

LONG-TERM INDEBTEDNESS OBLIGATIONS

The following summary of our long-term indebtedness obligations includes:
scheduled principal repayments for the next five years and after;
weighted average interest rates for debt maturing in each of the next five years and after and
estimated fair values of outstanding obligations.

We estimate the fair value of our debt instruments using quoted market prices we received for the same types and issues of our debt or on the discounted value of the future cash flows using market yields for the same type and comparable issues of debt. Changes in market rates of interest affect the fair value of our fixed-rate debt.
