NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

FOR THE QUARTERS AND ~~YEAR-TO-DATE~~YEARS-TO-DATE ENDED SEPTEMBER 30, ~~2016~~2017 AND ~~2015~~2016

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~~taxable REIT ~~Subsidiary (TRS)~~subsidiaries (TRSs), which includes our ~~manufacturing businesses~~Wood Products segment and ~~the portion~~portions of our Timberlands and Real Estate, ~~and~~ Energy &and Natural Resources (Real Estate & ENR) ~~segments' income included in the TRS.~~segments.

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

majority-owned domestic and foreign subsidiaries and


•	~~the results of Plum Creek Timber Company, Inc. (Plum Creek), for the period from February 19, 2016 (the merger date), to September 30, 2016 (see~~ ~~Note 4: Merger with Plum Creek), 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~~statements. Certain information and footnote disclosures normally ~~provided~~included in ~~accordance with accounting principles generally accepted in the United States~~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, ~~2015.~~2016. Results of operations for interim periods should not necessarily be regarded as ~~necessarily~~ indicative of the results that may be expected for the full year.

RECLASSIFICATIONS

We have reclassified certain balances and results from the prior year to be consistent with our ~~2016~~2017 reporting. This makes year-to-year comparisons easier. Our reclassifications had no effect on consolidated net earnings or equity.

Our reclassifications present ~~1) our~~the adoption of new accounting pronouncements ~~and 2) the results of discontinued operations separately from results of continuing operations~~ on our Consolidated Statement of Operations, ~~Consolidated Balance Sheet~~ and in the related footnotes. ~~Note 3: Discontinued Operations~~ ~~provides information about our discontinued operations.~~

~~As a result~~Refer to discussion of ~~the merger, we have revised our business segments. Results for fiscal periods prior to 2016 have been revised to conform to the~~ new ~~segments and to exclude discontinued operations.~~ accounting pronouncements below.~~Note 2: Business Segments~~ ~~provides information about our revised business segments.~~

NEW ACCOUNTING PRONOUNCEMENTS

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, a comprehensive new revenue recognition model that requires an entity to recognize revenue to depict the transfer of goods or services to customers at an amount that reflects the consideration it expects to receive in exchange for those goods or services. In August 2015, FASB issued ASU 2015-14, which deferred the effective date for an additional year. In March 2016, FASB issued ASU 2016-08, which does not change the core principle of the guidance; however, it does clarify the implementation guidance on principal versus agent considerations. In April 2016, FASB issued ASU 2016-10, which clarifies two aspects of ASU 2014-09: identifying performance obligations and the licensing implementation guidance. In May 2016, FASB issued ASU 2016-12, which amends ASU 2014-09 to provide improvements and practical expedients to the new revenue recognition model. ~~We plan~~In December 2016, the FASB issued ASU 2016-20, which amends ASU 2014-09 for technical corrections and to correct for unintended application of the guidance. In February 2017, FASB issued ASU 2017-05, which clarifies the scope of ASC 610-20 and impacts accounting for partial sales of nonfinancial assets.

The company expects to adopt ~~these accounting standard updates on~~and implement the new revenue recognition guidance effective January 1, ~~2018, and have not yet determined whether we will use~~2018. The new standard is required to be applied retrospectively to each prior reporting period presented (full retrospective transition method) or retrospectively with the ~~retrospective or~~ cumulative effect ~~transition~~of initially applying it recognized at the date of initial application (cumulative effect method). We expect to adopt using the cumulative effect method. We ~~anticipate~~expect that ~~this standard will increase~~ the ~~volume~~adoption of ~~disclosures about our~~the new revenue ~~transactions, but~~recognition guidance will not materially impact our ~~consolidated financial statements.~~

In April 2015, FASB issued ASU 2015-03, which amends the presentation of debt issuance costs on the consolidated balance sheet. Under the new guidance, debt issuance costs are presented as a direct deduction from the carrying amount of the debt liability rather than as an asset. The new guidance is effective retrospectively for fiscal periods beginning after December 15, 2015. We adopted on January 1, 2016, and have reclassified balances of debt issuance costs accordingly in our consolidatedoperating results, balance sheet, ~~and in related disclosures for all periods presented.~~

~~In May 2015, FASB issued ASU 2015-07, which clarifies the presentation within the fair value hierarchy of certain investments held within~~or cash flows. We expect an impact to our pension plan. The new guidance is effective retrospectively for fiscal periods starting after December 15, 2015. This new guidance removes the requirement to categorize within the fair value hierarchy investments for which fair value is measured using the net asset value per share as a practical expedient and, instead, permits separate disclosure. Upon adoption these investments are presented separatelyfinancial reporting from ~~the fair value hierarchy and reconciled to total investments in our consolidated financial statements and related~~adding expanded disclosures. ~~We adopted on January 1, 2016.~~

In July 2015, FASB issued ASU 2015-11, which simplifies the measurement of inventories valued under most methods, including our inventories valued under FIFO – the first-in, first-out – and moving average cost methods. Inventories valued under LIFO – the last-in, first-out method – are excluded. Under this new guidance, inventories valued under these methods would be valued at the lower of cost or net realizable value, with net realizable value defined as the estimated selling price less reasonable costs to sell the inventory. ~~The new guidance is effective prospectively for fiscal periods starting after December 15, 2016, and early adoption is permitted.~~ We ~~expect to adopt~~adopted ASU 2015-11 on January 1, 2017, and dodetermined this pronouncement does not ~~expect adoption to materially~~have a material impact on our consolidated financial statements and related disclosures.

In September 2015, FASB issued ASU 2015-16, which results in the ability to recognize, in current period earnings, any changes in provisional amounts during the measurement period after the closing of an acquisition, instead of restating prior periods for these changes. We adopted on January 1, 2016. Measurement period adjustments related to our merger with Plum Creek did not have a material impact to earnings or cash flows for the quarter and year-to-date period ended September 30, 2016.

In February 2016, FASB issued ASU 2016-02, which requires lessees to recognize assets and liabilities for the rights and obligations created by those leases and requires both capital and operating 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 expect to adopt ASU 2016-02 on January 1, 2019, and are evaluating the impact on our consolidated financial statements and related disclosures.

In March 2016, FASB issued ASU 2016-09, which simplifies several aspects of accounting for share-based payment transactions, including income tax consequences, award classification, cash flows reporting, and forfeiture rate application. Specifically, the update requires all excess tax benefits and tax deficiencies to be recognized as income tax expense or benefit in the income statement with a cumulative-effect adjustment to equity as of the beginning of the period of adoption. The update allows excess tax benefits to be classified along with other income tax cash flows as an operating activity on the statement of cash flows. When accruing compensation cost, an entity can make an entity-wide accounting policy election to either estimate the number of awards expected to vest or to account for forfeitures as they occur with a cumulative-effect adjustment to equity as of the beginning of the period

of adoption. The update requires cash paid by an employer when directly withholding shares for tax-withholding purposes to be classified as a financing activity on the statement of cash flows, applied retrospectively. This guidance is effective for fiscal years beginning after December 15, 2016. As permitted, we elected to adopt early, and applied the different aspects as prescribed by the standard effective January 1, 2016. The adoption of this guidance represents a change in accounting policy and did not have a material impact on our consolidated financial statements. Shares withheld by the employer for tax-withholding purposes for the nine months ended September 30, 2015, of $11 million were retrospectively reclassified from an operating activity to a financing activity in the ~~Consolidated Statement of Cash Flows~~.

In August 2016, FASB issued ASU 2016-15, which reduces diversity in practice in how certain transactions are classified in the statement of cash flows. These transactions include: debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle. The new guidance is effective for fiscal years beginning after December 15, 2017, and early adoption is permitted. We have adopted this update effective July 1, 2016, and our adoption did not materially impact our Consolidated Statement of Cash Flows.

In October 2016, FASB issued ASU 2016-16, which requires immediate recognition of the income tax consequences upon intra-entity transfers of assets other than inventory. The new guidance is effective for annual periods beginning after December 15, 2017, and early adoption is permitted. We ~~expect to adopt~~adopted this accounting standard ~~update~~ on January 1, 2017. As a result of this adoption, our opening balance sheet was adjusted through "Retained earnings" to include a deferred tax asset of $22 million for prior period intra-entity transfers. Adoption of this standard did not have a material impact on our Consolidated Statement of Cash Flows or Consolidated Statement of Operations.

In March 2017, FASB issued ASU 2017-07, which requires that an employer report the service cost component of pension and other postretirement benefit costs in the Consolidated Statement of Operations in the same line item or items as other compensation costs arising from services rendered by the pertinent employees. This requirement is consistent with how we have historically presented our pension service costs. The other requirement of ASU 2017-07 is to present the remaining components of pension and other postretirement benefit costs (i.e., interest, expected return on plan assets, amortization of actuarial gains or losses, and amortization of prior service credits or costs) in the Consolidated Statement of Operations separately from the service cost component and outside a subtotal of income from operations. The new guidance is effective for annual periods beginning after December 15, 2017, and doearly adoption is permitted. We adopted this accounting standard as of January 1, 2017. As a result, we reclassified amounts related to other components of pension and other post retirement benefit costs from their prior financial statements captions ("Costs of products sold," "General and administrative expenses," and "Other operating costs (income), net") into a new financial statement caption titled "Non-operating pension and other postretirement benefit (costs) credits" in our Consolidated Statement of Operations. The adoption of ASU 2017-07 did not ~~expect adoption to materially~~impact "Net earnings," nor did it impact our ~~consolidated financial statements and related disclosures.~~

Consolidated Balance Sheet.

NOTE 2: BUSINESS SEGMENTS

Reportable business segments are determined based on the company’s ~~management approach. The management~~"management approach," as defined by FASB ASC 280, “Segment ~~Reporting,~~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.

During fiscal year 2016, the company’s chief operating decision maker changed the information regularly reviewed for making decisions to allocate resources and assess performance. As a result, the company will report its financial performance based on three business segments: Timberlands, Real Estate & ENR, and Wood Products. Prior to revising our segment structure, activities related to the Real Estate & ENR business segment were reported as part of the Timberlands business segment.

~~Amounts for all periods presented have been reclassified throughout the consolidated financial statements and disclosures to conform to the new segment structure.~~

We are principally engaged in growing and harvesting ~~timber,~~timber; manufacturing, distributing, and selling products made from ~~trees, as well as~~trees; maximizing the value of every acre we own through the sale of higher and better use (HBU) ~~properties~~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 ~~our Uruguay operations;~~leased recreational access;


•	Real Estate & ENR – which includes sales of ~~HBU~~timberlands; rights to explore for and ~~non-core timberlands,~~extract hard minerals, oil and gas ~~coal~~production and ~~other natural resources,~~coal; and equity interests in our Real Estate Development Ventures (as defined and described in Note 7: Related Parties); and

Wood Products – which includes softwood lumber, engineered wood products, ~~oriented strand board, plywood,~~structural panels, medium density fiberboard and building materials distribution.

Discontinued operations as presented herein consist of the operations of our former Cellulose Fibers segment, and relate to assets and liabilities that have been reclassified as discontinued operations on our balance sheet as of September 30, 2016. All periods presented have been revised to separate the results of discontinued operations

~~from the results of our continuing operations~~. ~~Refer to~~ ~~Note 3: Discontinued Operationsfor more information regarding our discontinued operations.~~

On October 12, 2016, we announced the exploration of strategic alternatives for our timberlands and manufacturing operations in Uruguay. We intend to consider a broad range of alternatives, including continuing to hold and operate the business, or a sale.

An analysis and reconciliation of our business segment information to the respective information in the Consolidated Statements of Operations is as follows:

(1)

Net contribution to earnings for the Timberlands segment includes a 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, which was announced in June 2017 and completed on September 1, 2017. Refer to Note 3: Discontinued Operations and Other Divestituresfor more information regarding this transaction.


(2)	The Real Estate & ENR segment includes the equity earnings from, ~~and~~ investments in and advances to our Real Estate Development Ventures (as defined and described in Note 7: Related Parties), which are accounted for under the equity method.

~~(2)~~(3)

Net contribution to earnings for the Wood Products segment includes pretax charges of $190 million and $240 million incurred in the quarter and year-to-date period ended September 30, 2017, respectively, to accrue for estimated costs to remediate an issue with certain I-joists coated with our Flak Jacket® Protection product. Refer to Note 16: Charges for Product Remediation for additional details.

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, pension and postretirement costs, foreign exchange transaction gains and losses associated with financing, ~~equity earnings from our Timberland Venture, (as defined~~ and ~~described in~~ ~~Note 7: Related Parties~~), the elimination of intersegment profit in inventory and the LIFO reserve. Additionally, amounts shown for 2016 include equity earnings from our former Timberland Venture. As of August 31, 2016, the Timberland Venture became a fully consolidated, wholly-owned subsidiary and therefore eliminated our equity method investment at that time.

OPERATIONS DIVESTED

On ~~November 8, 2015, Weyerhaeuser~~October 12, 2016, we announced ~~that the board authorized~~ the exploration of strategic alternatives for ~~its Cellulose Fibers~~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 ~~May~~September 1, 2017, we completed the sale of our Uruguay timberlands and manufacturing operations for approximately $403 million of cash proceeds. Due to the 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. As of September 30, 2017, no assets or liabilities related to our Uruguayan operations remain on the Consolidated Balance Sheet.

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.

DISCONTINUED OPERATIONS

During 2016, we entered into ~~an agreement~~three separate transactions to sell our Cellulose Fibers ~~pulp business to International Paper for $2.2~~business. As a result of these transactions, the company recognized a pretax gain on disposition of $789 million and total cash proceeds of $2.5 billion in ~~cash. The pulp business consists~~the second half of five pulp mills located in Columbus, Mississippi; Flint River, Georgia; New Bern, North Carolina; Port Wentworth, Georgia and Grande Prairie, Alberta, and two modified fiber mills located in Columbus, Mississippi and Gdansk, Poland. This transaction is expected to close in fourth quarter 2016 and is subject to customary closing conditions, including regulatory review. We will continue to operate separately from International Paper until the transaction closes.2016. These transactions consisted of:

~~On June 15, 2016, we entered into an agreement to sell~~sale of our Cellulose Fibers liquid packaging board business to Nippon Paper Industries Co., ~~Ltd., for $285 million in cash. Our liquid packaging board business consisted of one mill located in Longview, Washington. On~~Ltd, which closed on August 31, ~~2016, we completed the~~ 2016;

sale ~~and recognized a pre-tax gain~~ of ~~$60 million, which is included in "Earnings from discontinued operations, net of income taxes" on the~~ ~~Consolidated Statement of Operations~~.

~~On October 4, 2016, we entered an agreement to sell~~ our ~~interest in our~~Cellulose Fibers printing papers joint venture to One Rock Capital Partners, ~~LLC. The transaction includes the printing papers mill located in Longview, Washington. This transaction is expected to close in the fourth quarter~~LLC, which closed on November 1, 2016; and

sale of ~~2016 and is subject to customary closing conditions. The printing papers joint venture will continue to operate separately from One Rock until the transaction closes.~~

~~The assets and liabilities of the~~our Cellulose Fibers pulp business ~~along with our investment in our printing papers joint venture, met the criteria necessary~~ to ~~be classified as held-for-sale during second quarter 2016 and continue to meet those criteria as of September 30,~~International Paper, which closed on December 1, 2016. ~~It is our expectation that the sales of these assets are probable and will be completed within one year.~~

~~Results~~The results of operations for our pulp and liquid packaging board businesses, along with our interest in our printing papers joint venture, ~~have been~~were reclassified to discontinued ~~operations. These~~ operations ~~were previously reported as the Cellulose Fibers segment.~~during our 2016 reporting year. These results have been summarized in "Earnings from discontinued operations, net of income taxes" on our Consolidated Statement of Operations for each period presented. ~~The related assets and liabilities of these operations met the criteria for classification as "held for sale" and have been reclassified as discontinued operations on our~~ ~~Consolidated Balance Sheetfor each date presented.~~ We did not reclassify our Consolidated Statement of Cash Flows to reflect discontinued operations.

~~We expect to use after-tax proceeds from our sales of our discontinued operations for repayment of long-term debt.~~

The following table presents net earnings from discontinued operations. As all discontinued operations were sold in 2016, no assets or liabilities remain as of September 30, 2017, or December 31, 2016.

NOTE 4: MERGER WITH PLUM CREEK

On February 19, 2016, we merged with Plum Creek Timber Company, Inc. (Plum Creek). Plum Creek was a REIT that primarily owned and managed timberlands in the United States. Plum Creek also produced wood products, developed opportunities for mineral and other natural resource extraction, and sold real estate properties. The merger combined two industry leaders. The breadth and diversity of our combined timberlands, real estate, energy and natural resources assets, and wood products operations position Weyerhaeuser to capitalize on the improving housing market and to continue to capture HBU land values across the combined portfolio.

Under the merger agreement, each issued and outstanding share of Plum Creek common stock was exchanged for 1.60 Weyerhaeuser common shares, with cash paid in lieu of any fractional shares. Upon consummation of the merger, all outstanding Plum Creek stock options (all fully vested as of the merger date) and restricted stock units were converted into Weyerhaeuser stock options and restricted stock units, after giving effect to the 1.60 exchange ratio. Because the Plum Creek stock options were fully vested and relate to services rendered to Plum Creek prior to the merger, the replacement stock options were also fully vested and their fair value is included in the consideration transferred. Replacement restricted stock units relate to services to be performed post-merger and therefore were not included in consideration transferred. See additional details about replacement share-based payment awards in ~~Note 14: Share-based Compensation~~.

The acquisition of total assets of $10.0 billion was a noncash investing and financing activity comprised of $6.4 billion in equity consideration transferred and $3.6 billion of liabilities assumed. ~~See~~ ~~Note 10: Long-term Debt and Lines of Credit~~ ~~for additional details of indebtedness assumed.~~

~~The following table summarizes the equity consideration transferred in the merger:~~

We recognized $14 million and $132 million of merger-related costs that were expensed during the quarter and year-to-date period ended September 30, 2016, respectively. We also recognized $14 million of merger-related costs that were expensed during the fourth quarter of 2015. See ~~Note 15: Charges for Integration and Restructuring, Closures, and Asset Impairments~~ ~~for descriptions of the components of merger-related costs. These costs are included in "Charges for integration and restructuring, closures and asset impairments" in our~~ ~~Consolidated Statement of Operations~~.

As a result of progress made to integrate financial systems since the merger date, the amount of revenue and loss before income taxes from acquired Plum Creek operations is no longer practicable to disclose for the quarter and and year-to-date period ended September 30, 2016.

Pro forma ~~net~~"Net earnings from continuing operations attributable to Weyerhaeuser common ~~shareholders exclude~~shareholders" excludes $10 million and $144 million of non-recurring merger-related costs (net of tax) incurred in the quarter and year-to-date ~~period~~ ended September 30, 2016, respectively. ~~No non-recurring merger-related costs were incurred during the quarter or year-to-date period ended September 30, 2015.~~ Pro forma data may not be indicative of the results that would have been obtained had these events occurred at the beginning of the periods presented, nor is it intended to be a projection of future results.

Weyerhaeuser has accounted for the merger transaction as the acquirer and has applied the acquisition method of accounting. Under the acquisition method, the assets acquired and liabilities assumed by Weyerhaeuser from Plum Creek were recorded as of the date of the acquisition at their respective estimated fair values.

The fair values of the assets acquired and liabilities assumed were preliminarily determined using the income, cost or market approaches. The fair value measurements were generally based on significant inputs that are not observable in the market and thus represent Level 3 measurements as defined in ASC 820, ~~Fair Value Measurement~~, with the exception of certain long-term debt instruments assumed in the acquisition that can be valued using observable market inputs and are therefore Level 2 measurements. The income approach was primarily used to value acquired timberlands, minerals and mineral rights, equity investments in the Timberland Venture (as defined and described in ~~Note 7: Related Parties) and Real Estate Development Ventures (as defined and described in~~ ~~Note 7: Related Parties), and the Note Payable to Timberland Venture (as defined and described in~~ ~~Note 7: Related Parties~~). The income approach estimates fair value for an asset based on the present value of cash flow projected to be generated by the asset. Projected cash flows are discounted at rates of return that reflect the relative risk of achieving the cash flows and the time value of money. The cost approach, which estimates value by determining the current cost of replacing an asset with another of equivalent economic utility, was used, as appropriate, for property and equipment. The cost to replace a given asset reflects the estimated reproduction or replacement cost for the property, less an allowance for loss in value due to depreciation. The market approach was primarily used to value higher and better use real estate tracts included within acquired timberlands, certain land and building assets included within acquired property and equipment, and long-term debt instruments. The market approach estimates fair value for an asset based on values of recent comparable transactions.

The initial allocation of purchase price was recorded using preliminary estimated fair value of assets acquired and liabilities assumed based upon the best information available to management at the time. The purchase price allocation was updated in the third quarter 2016. The measurement period adjustments reflect additional information obtained to record the fair value of certain assets acquired and liabilities assumed based on facts and circumstances existing as of the acquisition date. Measurement period adjustments reflected below did not have a material impact to earnings and had no impact to cash flows for the quarter or year-to-date period ended September 30, 2016.

~~Initial and updated preliminary estimated fair values of identifiable assets acquired and liabilities assumed as of the merger date are as follows:~~

These estimated fair values are preliminary in nature and subject to further adjustments, which could be material. We have not identified any material unrecorded pre-merger contingencies where the related asset, liability or impairment is probable and the amount can be reasonably estimated. We are in the process of finalizing our valuations related to the following:

~~timber and timberlands,~~

~~minerals and mineral rights, and~~

~~other contractual rights and obligations.~~

Our valuations will be finalized when certain information arranged to be obtained has been received and our review of that information has been completed. Prior to the finalization of the purchase price allocation, if information becomes available that would indicate it is probable that such events had occurred and the amounts can be reasonably estimated, such items will be included in the final purchase price allocation.

NOTE 5: ~~NET EARNINGS PER SHARE AND SHARE REPURCHASES~~

NET EARNINGS PER SHARE

Our basic and diluted earnings per share attributable to Weyerhaeuser shareholders were:

$0.17 during third quarter 2017 and $0.41 during year-to-date 2017; and

$0.30 during third quarter 2016 and $0.64 during year-to-date ~~2016; and~~

~~$0.35 during third quarter 2015 and $0.78 during year-to-date 2015.~~

~~Our diluted earnings per share attributable to Weyerhaeuser shareholders were:~~

~~$0.30 during third quarter 2016 and $0.64 during year-to-date 2016; and~~

~~$0.35 during third quarter 2015 and $0.77 during year-to-date 2015.~~2016.

Basic earnings per share is net earnings available to common shareholders 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 available to common shareholders divided by the sum of the weighted average number of our outstanding common shares and the effect of our outstanding dilutive potential common shares:

We use the treasury stock method to calculate the dilutive effect of our outstanding stock options, restricted stock units and performance share units. Share-based payment awards that are contingently issuable upon the achievement of specified performance or market conditions are included in our diluted earnings per share calculation in the period in which the conditions are satisfied.

As described below, on July 1, 2016, all outstanding Preference Shares were converted into common shares. For all periods presented the Preference Shares were antidilutive as determined using the if-converted method.

Potential Shares Not Included in the Computation of Diluted Earnings per Share

The following shares were not included in the computation of diluted earnings per share because they were either antidilutive or the required performance or market conditions were not met. Some or all of these shares may be dilutive potential common shares in future periods.

~~Through~~ our ~~merger with Plum Creek on February 19, 2016, we acquired equity interests in the~~ Real Estate Development Ventures ~~and~~(as defined below), which are accounted for using the ~~Timberland Venture. Additionally, through the merger Weyerhaeuser assumed the benefits~~equity method and ~~obligations associated with the formation of~~

Real Estate Development Ventures

WestRock-Charleston Land Partners, LLC (WR-CLP) is a limited liability company which holds residential and commercial real estate development properties, currently under development (Class A Properties) and higher-value timber and development lands (Class B Properties) ~~(referred~~(Class A Properties and Class B Properties referred to collectively as the Real Estate Development Ventures). We have a 3 percent interest in Class A Properties and a 50 percent interest in Class B Properties. WestRock Company is the other member of WR-CLP and owns 97 percent of the Class A Properties and 50 percent of the Class B Properties. The Company uses the equity method for both its Class A and Class B interests. Our share of the equity earnings ~~are~~of WR-CLP is included in the net contribution to earnings of our Real Estate & ENR segment.

WR-CLP is a variable interest entity and is financed by regular capital calls from the manager of WR-CLP in proportion to a member’s ownership interest. If a member does not make a capital contribution, the member’s ownership interest is diluted. We are committed to make additional capital contributions of up to $26 million during the remaining term of the venture which expires in 2020. We do not intend to provide any additional sources of financing for WR-CLP.

We are not the primary beneficiary of WR-CLP. We consider the activities that most significantly impact the economic performance of WR-CLP to be the day-to-day operating decisions along with the oversight responsibilities for the real estate development projects and properties. WestRock Company (the other equity member) has the power to direct the activities of WR-CLP that most significantly impact its economic performance through its ability to manage the day-to-day operations of WR-CLP. WestRock Company also has the ability to control all management decisions associated with all Class A and Class B Properties through its majority representation on the board of directors for the Class A Properties and due to its equal representation on the board of directors for the Class B Properties.

~~Our maximum exposure to loss is $73 million, the~~The carrying amount of our investment in WR-CLP is $33 million at September 30, ~~2016, plus any required future capital contributions.~~

~~Timberland Venture~~

~~Beginning on the date of~~2017, and $56 million at December 31, 2016. The change in our merger with Plum Creek until August 31, 2016, we held preferred and common interests in Southern Diversified Timber, LLC, a timberland joint venture (Timberland Venture), which included 100 percent of the preferred interests and 9 percent of the common interests. The Timberland Venture’s other member, an affiliate of Campbell Global LLC (TCG Member), held 91 percent of the Timberland Venture’s common interests. The activities of the Timberland Venture consisted primarily of owning, growing, managing and sustaining its Southern timberlands, entering into cutting contracts with an affiliate of Campbell Global LLC for the sale and harvest of timber and owning a promissory note payable to the Timberland Venture (Note Payable to Timberland Venture) and collecting interest thereon. Our investment in WR-CLP during 2017 is due to a $23 million cash return of investment received during 2017. Additionally, we had $1 million of equity earnings from the joint ventures during third quarter and year-to-date 2017. These equity earnings were distributed during third quarter 2017. We record our share of ~~the equity~~net earnings ~~of the Timberland Venture was not attributed to one of our business segments, and was reported~~within "Equity earnings from joint ventures" in ~~Unallocated Items.~~

On August 31, 2016, the Timberland Venture redeemed TCG Member’s interest. Upon the redemption, the Timberland Venture distributed all of the timberlands, a portion of the cash balance, and other net assets to TCG Member equal in total to the fair value of TCG Member's adjusted capital account. Following the redemption and distribution of assets to TCG Member, the Timberland Venture's remaining assets consisted of cash and a note receivable from Weyerhaeuser.

As we now hold all of the equity interests in the Timberland Venture, we have consolidated it as a wholly-owned subsidiary and eliminated our equity method investment in the Timberland Venture. As a result, the Note Payable to Timberland Venture is now eliminated for financial reporting purposes in consolidation as it is now intercompany indebtedness and therefore no longer appears on our ~~Consolidated Balance Sheet~~.

In conjunction with the redemption of TCG Member, we remeasured our previously held equity interest to fair value at August 31, 2016, resulting in recognition of a gain of $6 million in "Interest income and other" on our Consolidated Statement of Operations ~~during~~in the ~~third quarter of 2016.~~period which earnings are recorded by the affiliates.

Twin Creeks Venture

On April 1, 2016, we contributed approximately 260,000 acres of our southern timberlands with an agreed-upon value of approximately $560 million to Twin Creeks Timber, LLC (Twin Creeks Venture), in exchange for cash of approximately $440 million and a 21 percent ownership interest. ~~The other members contributed cash of approximately $440 million for a combined 79 percent ownership interest.~~

The Twin Creeks Venture is expected to raise total committed capital of up to $950 million from its investors over the next several years. We expect to maintain a 21 percent ownership interest and to contribute additional capital of up to $85 million during the next several years. Unless extended by unanimous vote of all the investors, the term of the Twin Creeks Venture is 15 years.

In conjunction with contributing to the venture, we entered into a separate ~~agreement~~agreements to manage the timberlands owned by the Twin Creeks Venture, including harvesting activities, marketing and log sales activities, and replanting and silviculture activities. ~~This~~These management ~~agreement guarantees~~agreements guaranteed the Twin Creeks Venture an annual return equal to 3 percent of the ~~venture~~contributed value of the managed timberlands in the form of minimum quarterly payments from ~~us equal to 3 percent of the fair value of the managed timberlands.~~Weyerhaeuser.

~~our balance sheet does not reflect~~ our 21 percent ownership interest in the Twin Creeks ~~Venture.~~Venture for $108 million in cash. We do not expect to recognize a material gain or loss on the redemption of our ownership interest. Effective December 31, 2017, we will also terminate the agreements under which we have managed the Twin Creeks timberlands. Following termination of these agreements, Weyerhaeuser will have no further responsibilities or obligations related to Twin Creeks. In conjunction with the redemption and termination discussed above, we have also entered into an agreement to sell 100,000 acres of our timberlands to Twin Creeks for $203 million. The sale, which will include 80,000 acres of timberlands in Mississippi and 20,000 acres in Georgia, is expected to close by the end of fourth quarter 2017.

~~The receipt of $440 million was classified as a cash flow from investing activities~~

These cash flows are included in "Other" cash flows from investing activities in our ~~Consolidated Statement of Cash Flows~~.during 2017 were as follows:

~~All revenues and expenses from our harvest and sale of standing timber from the contributed timberland will continue to be reported in our~~ ~~Consolidated Statement of Operations~~ ~~and attributed to our Timberlands business segment as though the contribution had not occurred.~~

~~ASSUMED PLANS FROM MERGER WITH PLUM CREEK~~

Upon our merger with Plum Creek, we assumed one qualified pension plan and two nonqualified pension plans. All active participants in these plans became fully vested and the plans were frozen as of February 19, 2016. The cumulative funded status of the assumed plans as of February 19, 2016, was a net liability of $62 million.

The expected return on assets for the qualified plan assumed is 7 percent. Assets of $47 million related to the nonqualified plans are held in a grantor trust and are subject to the claims of creditors in the event of bankruptcy. As a result, these are not considered plan assets and have not been netted against the nonqualified pension liability. These assets are included in "Other assets" in our~~Consolidated Balance Sheet~~.

~~During first quarter 2016,~~On January 1, 2017, we ~~recognized $5 million~~adopted ASU 2017-07, which affects where components of pension ~~benefit~~and other postretirement costs ~~from change in control provisions for certain Plum Creek executives.

Refer to Note ~~15: Charges~~1: Basis of Presentation for ~~Integration and Restructuring, Closures and Impairments). We did not recognize any additional costs for change in control provisions during the second or third quarters of 2016.~~further information.

During third quarter 2016, we made $37 million of nonqualified pension benefits payments, which included a portion of the enhanced benefits triggered by change in control provisions. These were paid using proceeds from sales of assets held in grantor trusts.

FAIR VALUE OF PENSION PLAN ASSETS AND OBLIGATION

We estimate the fair value of pension plan assets based upon the information available during the year-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 ~~updated~~update the year-end estimated fair value of pension plan assets to incorporate year-end net asset values reflected in financial statements received after we have filed our Annual Report on Form 10-K. During second quarter ~~2016,~~2017, we recorded an increase in the fair value of the pension assets of $7$17 million, or less than 1 percent. We also updated our census data that is used to estimate our projected benefit obligation for our pension ~~and other postretirement benefit~~ plans. As a result of that update, during second quarter ~~2016,~~2017, we recorded ~~an increase~~a decrease to the projected benefit obligation of $1$10 million, or less than 1 percent. The net effect was a $6$27 million ~~increase~~improvement in the funded ~~status.~~

~~Consistent with accounting for the merger as the acquirer in a business combination (see~~ ~~Note 4: Merger with Plum Creek), pension assets and benefit obligations for plans assumed from Plum Creek were re-measured~~status compared to reflect their fair value as of the merger date. This included updating asset values, updating discount rates to reflect market conditions as of the date of the merger, and freezing benefit accruals. The fair value of these items as of February 19, 2016, were as follows:

~~$137 million qualified pension plan assets;~~

~~$149 million qualified pension plan projected benefit obligation; and~~

~~$50 million nonqualified pension plan projected benefit obligation.~~

~~No adjustments were made to the fair value of assets or projected benefit obligations of plans assumed from Plum Creek during the second or third quarter.~~December 31, 2016.

EXPECTED CONTRIBUTIONS AND BENEFIT PAYMENTS

In ~~2016~~2017 we expect to:

be required to contribute approximately ~~$17~~$23 million for our Canadian registered plan;

be required to contribute or make benefit payments for our Canadian nonregistered plans of $3 million;

make benefit payments of ~~$57~~$26 million for our U.S. nonqualified pension ~~plans, including $38 million of benefit payments for plans assumed from Plum Creek to be paid out of assets held in grantor trusts;~~plans; and

make benefit payments of ~~$22~~$21 million for our U.S. and Canadian other postretirement plans.

We do not anticipate making a contribution to our U.S. qualified pension plans ~~for 2016.~~in 2017.

NOTE 10: LONG-TERM DEBT AND LINES OF CREDIT

~~This note provides details about our:~~

~~long-term debt assumed in the Plum Creek merger and~~

~~new term loans issued.~~

~~LONG-TERM DEBT ASSUMED IN THE PLUM CREEK MERGER~~

~~Through our merger with Plum Creek, we assumed long-term debt instruments consisting of:~~

~~two issuances of publicly traded Senior Notes;~~

~~an Installment Note (defined and described below); and~~

~~the Note Payable to Timberland Venture (defined and described below).~~

~~Concurrent with the merger, we repaid in full the outstanding balances of Plum Creek's Revolving Line of Credit and Term Loan using $720 million of cash on hand.~~

~~Senior Notes~~

The assumed Senior Notes are publicly traded and were issued by Plum Creek Timberlands, L.P. (PC Timberlands) and were fully and unconditionally guaranteed by Weyerhaeuser Company as of the acquisition date. During the third quarter 2016, PC Timberlands was merged into Weyerhaeuser Company and Weyerhaeuser Company assumed the obligations. There were two separate issuances of Senior Notes: $569 million (principal) of 4.70 percent notes which mature in 2021 and $325 million (principal) of 3.25 percent notes which mature in 2023. The Senior Notes are redeemable prior to maturity; however, they are subject to a premium on redemption, which is based upon interest rates of U.S. Treasury securities having similar average maturities.

Through preliminary acquisition accounting the Senior Notes were recognized at estimated fair values of $614 million for the 4.70 percent notes and $324 million for the 3.25 percent notes as of the acquisition date. The differences between cash interest payments and the amounts recorded as interest expense at the effective market rates will adjust the carrying values of the notes to the principal amounts at maturity.

~~Installment Note~~

We assumed an installment note (Installment Note) payable to WestRock Land and Development, LLC (WR LD) that was issued in connection with Plum Creek's acquisition of certain timberland assets. The principal balance of the Installment Note is $860 million. Following the issuance, WR LD pledged the installment note to certain banks. The annual interest rate on the Installment Note is fixed at 5.207 percent. Interest is paid semi-annually with the principal due upon maturity in December 2023. The term may be extended at the request of the holder if the company at the time of the request intends to refinance all or a portion of the Installment Note for a term of five years or more. The Installment Note is generally not redeemable prior to maturity except in certain limited circumstances and could be subject to a premium on redemption.

We receive patronage refunds under the Installment Note. Patronage refunds are distributions of profits from banks in the farm credit system, which are cooperatives that are required to distribute profits to their members. Patronage distributions, which are made in either cash or stock, are received in the year after they were earned and are recorded as offsets to interest expense.

Through preliminary acquisition accounting, the Installment Note was recognized at an estimated fair value of $893 million as of the acquisition date. The difference between the cash interest payments and the amount being recorded as interest expense at the effective market rate will reduce the carrying value of the Installment Note to the principal amount at the maturity date.

~~Note Payable to Timberland Venture~~

We assumed the Note Payable to Timberland Venture, which has a principal balance of $783 million. The annual interest rate on the Note Payable to Timberland Venture is fixed at 7.375 percent. Interest is paid quarterly with the

~~principal due upon maturity. The note matures on October 1, 2018, but may be extended until October 1, 2020, at our election. The note is not redeemable prior to maturity.~~

Through preliminary acquisition accounting, the Note Payable to Timberland Venture was recognized at an estimated fair value of $838 million as of the acquisition date. The difference between the cash interest payments and the amount being recorded as interest expense at the effective market rate will reduce the carrying value of the note to the principal amount at the maturity date.

On August 31, 2016, the Timberland Venture redeemed TCG Member's interest and Weyerhaeuser obtained full ownership of the Timberland Venture's equity. As a result, we consolidated the Timberland Venture as a wholly-owned subsidiary and the Note Payable to Timberland Venture is therefore eliminated for financial reporting purposes upon consolidation as it is now intercompany indebtedness. The redemption transaction and consolidation is described in ~~Note 7: Related Parties~~.

~~NEW TERM LOANS ISSUED~~

~~During February 2016 and subsequent to completion of the Plum Creek merger,~~March 2017, we entered into a ~~$600 million 18-month~~new $1.5 billion five-year senior unsecured ~~term loan maturing~~revolving credit facility that expires in ~~August 2017.~~March 2022. This replaced a $1 billion senior unsecured revolving credit facility that was set to expire September 2018. The entire amount is available to Weyerhaeuser Company. Borrowings are ~~currently~~ at LIBOR plus ~~1.05 percent. At~~a spread or at other interest rates mutually agreed upon between the borrower and the lending banks. As of September 30, ~~2016, we had $600 million outstanding under this facility.~~2017, there were no borrowings outstanding.

During ~~March 2016,~~July 2017, we ~~entered into~~prepaid a ~~$1.9 billion 18-month senior unsecured~~$550 million variable-rate term loan ~~maturing~~originally set to mature in ~~September~~2020 (2020 term loan). The 2020 term loan was prepaid using available cash of $325 million as well as borrowing proceeds from a new $225 million variable-rate term loan set to mature in 2026 (2026 term loan).

During August 2017, we paid our $281 million 6.95% debentures, originally set to mature in August 2017. ~~Borrowings are currently at LIBOR plus 1.05 percent. At September 30, 2016, we had $1,100 million outstanding under this facility.~~

NOTE 11: FAIR VALUE OF FINANCIAL INSTRUMENTS

The estimated fair values and carrying values of our long-term debt consisted of the following:


	SEPTEMBER 30, 2016				DECEMBER 31, 2015				SEPTEMBER 30, 2017				DECEMBER 31, 2016
DOLLAR AMOUNTS IN MILLIONS	CARRYING VALUE		FAIR VALUE (LEVEL 2)		CARRYING VALUE		FAIR VALUE (LEVEL 2)		CARRYING VALUE		FAIR VALUE (LEVEL 2)		CARRYING VALUE		FAIR VALUE (LEVEL 2)
Long-term debt (including current maturities):
Fixed rate	$	6,063	$	7,204	$	4,238	$	4,967	$	5,771	$	6,872	$	6,061	$	6,925
Variable rate	2,247		2,250		549		550		224		225		549		550
Total Debt	$	8,310	$	9,454	$	4,787	$	5,517	$	5,995	$	7,097	$	6,610	$	7,475

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

~~This note provides details about our:~~

~~legal proceedings and~~

~~environmental matters.~~

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 long-term consolidated financial position, results of operations or cash flows. See Note ~~17:~~18: Income Taxes for a discussion of a tax proceeding involving Plum ~~Creek REIT's~~Creek's 2008 U.S. federal income tax return.

ENVIRONMENTAL MATTERS

~~Our environmental matters include:~~

~~site remediation and~~

~~asset retirement obligations.~~

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. ~~In 2015, we received invitations from~~Several other companies also operated upstream pulp mills within the ~~EPA~~remediation site. We are currently cooperating with the other parties to ~~negotiate~~jointly implement an administrative order issued by the EPA on ~~consent for a contaminant removal action for~~April 14, 2016, with respect to a portion of the site comprising a stretch of the river approximately 1.7 miles long ~~that the EPA refers~~referred to as the Otsego Township Dam Area. Several other companies also operated upstream pulp mills, and two other parties received the same invitations. On April 14, 2016, the EPA issued an administrative order to the company and the other parties, the terms and scope of which are generally consistent with the company’s and the other parties’ discussions with the EPA. The company and the other parties have begun to jointly implement the administrative order. At this time weWe do not expect to incur material losses related to the implementation of this administrative order; however, we may incur additional costs, as yet not specified, in connection with remediation tasks resulting from other areas of the ~~administrative order.~~site. 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 the site. The trial has been concluded but a decision on cost contribution and allocation has not yet been rendered by the Court.

As of September 30, ~~2016,~~2017, our total accrual for future estimated remediation costs on the active Superfund sites and other sites for which we are responsible was approximately ~~$37~~$46 million. These reserves are recorded in "Accrued liabilities" (current) and "Other liabilities" (noncurrent) on our Consolidated Balance Sheet. ~~The accrual has not changed materially since the end of 2015.~~

Asset Retirement Obligations

We have obligations associated with the 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 September 30, ~~2016,~~2017, our accrued balance for these obligations was ~~$28~~$30 million. These obligations are recorded in "Accrued liabilities" (current) and "Other liabilities" (noncurrent) on our Consolidated Balance Sheet. The accruals have not changed materially ~~for continuing operations~~ since the end of ~~2015.~~2016.

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 CONTINGENCY

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 a pretax charge of $190 million and $240 million in the quarter and year-to-date period ended September 30, 2017, respectively, to accrue for remediation costs. Refer to Note 16: Charges for Product Remediation for further information.

STOCK OPTIONS AND STOCK APPRECIATION RIGHTS

We granted no stock ~~option~~options or stock appreciation rights during 2017, nor do we expect to make any such grants during the remainder of 2017.

VALUE MANAGEMENT AWARDS

Value Management Awards (VMAs) are relative performance equity incentive awards ~~issued as a result~~granted to certain former employees of Plum Creek and assumed by the company in connection with the Plum Creek merger. In accordance with the terms of the merger, with Plum Creek have similar exercise provisions as the terms of our current awards. All replacement stock option awards were fully vested prior to the date of the merger, so no expense will be recorded. The value of the replacement stock option awards was $5 million, which was included in the equity consideration issued in the merger as described in ~~Note 4: Merger with Plum Creek~~.

~~Replacement Restricted Stock Unit Awards~~

The replacement RSUs issued as a result of the merger with Plum Creek have similar vesting provisions as the terms of existing Weyerhaeuser restricted stock unit awards. Expense for replacement RSUs will continue to be recognized over the remaining service period unless a qualifying termination occurs. A qualifying termination of an awardee will result in acceleration of vesting and expense recognition in the period that the qualifying termination occurs. Qualifying terminations during year-to-date 2016 resulted in accelerated vesting of 686,096 of the replacement RSUs and recognition of $15 million of expense. This accelerated expense is included in merger-related integration costs as described in ~~Note 15: Charges for Integration and Restructuring, Closures and Asset Impairments~~.

~~Value Management Awards~~

~~Following the merger, the~~all VMAs ~~assumed were valued at target. All~~ outstanding ~~VMAs, if earned, will vest~~on December 31, 2017, will vest at “target” level performance of $100 per unit and will be paid in the first quarter of 2018. The VMAs are classified and accounted for as liabilities, as they will be settled in cash upon vesting. The expense recognized over the remaining performance period will equal the cash value of an award as of the last day of the performance period multiplied by the number of awards that are earned. Expense for VMAs will continue to be recognized over the remaining service period unless a qualifying termination occurs. A qualifying termination of ~~an awardee~~any holder of a VMA award before December 31, 2017, will ~~result in acceleration of~~accelerate vesting and expense recognition in the period that the qualifying termination occurs. ~~Qualifying terminations during year-to-date 2016 resulted in $6 million of expense recognized. This accelerated expense is included in merger-related integration costs as described in~~ ~~Note 15: Charges for Integration and Restructuring, Closures and Asset Impairments~~.

~~STOCK OPTIONS~~

Excluding replacement awards granted as a result of the merger, the weighted average exercise price of stock options granted to date in 2016 was $23.09. The vesting and post-termination vesting terms for stock options granted to date in 2016 were as follows:

~~vest ratably over four years, except for the replacement stock option awards granted as a result of the Plum Creek merger, which were fully vested as of the grant date;~~

~~vest or continue to vest in the event of death while employed, disability or retirement at an age of at least 62;~~

~~continue to vest upon retirement at an age of at least 62, but a portion of the grant forfeits if retirement occurs before the one year anniversary of the grant;~~

~~continue to vest for one year in the event of involuntary termination when the retirement criteria has not been met; and~~

INTEGRATION, RESTRUCTURING AND CLOSURES

During 2017, we incurred and accrued for termination benefits (primarily severance) and non-recurring professional services costs directly attributable to our merger with Plum Creek.

During 2016, we incurred and accrued for termination benefits (primarily severance), accelerated share-based payment costs, and accelerated pension benefits based upon ~~actual and expected~~ qualifying terminations of certain employees as a result of restructuring decisions made subsequent to the merger. We also incurred non-recurring professional services costs for investment banking, legal and consulting, and certain other fees directly attributable to our merger with Plum Creek.

During 2015, we recognized a noncash impairment charge of $13 million in first quarter 2015 related to a nonstrategic asset held in Unallocated Items that was sold in second quarter 2015. The fair value of the asset was determined using significant unobservable inputs (level 3) based on discounted cash flow model.

Changes in accrued severance related to restructuring during the year-to-date period ended September 30, ~~2016,~~2017, were as follows:

Accrued severance is recorded within the "Wages, salaries and severance pay" component of "Accrued liabilities" on our Consolidated Balance Sheet as detailed in Note 9: Accrued Liabilities. The majority of the accrued severance balance as of September 30, ~~2016,~~2017, is expected to be paid within one year.

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 operations 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 at June 30, 2017. 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 3: Discontinued Operations and Other Divestituresfor 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 a pending asset sale.

NOTE 16:CHARGES FOR 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. The company also announced it will cover the cost to either remediate or replace affected joists. The company estimates that approximately 2,400homes are affected.

The company recorded a liability of $50 million in second quarter 2017 based on the preliminary information that was available at that time. As remediation work has progressed, the company has obtained additional information and experience about the scope of the required remediation efforts and associated costs. Accordingly, we have adjusted our liability to account for the higher than originally expected cost per home for remediation, a modest increase in the estimated number of homes affected, as well as additional homebuilder and homeowner reimbursements. We recorded pretax charges of $190 million and $240 million in the quarter and year-to-date period ended September 30, 2017, respectively, to accrue for expected costs associated with the remediation. The charges are attributable to our Wood Products segment and were recorded in "Charges for product remediation," on the Consolidated Statement of Operations. As of September 30, 2017, $61 million has been paid out in relation to our remediation efforts. The remaining accrual of $179 million is recorded in "Accrued liabilities" on the Consolidated Balance Sheet. The company ultimately expects a significant portion of the total expense will be covered by insurance, however, as of the date of these financial statements no amounts related to potential recoveries have been recorded.

NOTE ~~17:~~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 ~~TRS,~~wholly-owned TRSs, which includes our ~~manufacturing businesses~~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 ~~2016~~2017 estimated annual effective tax rate for our ~~TRS~~TRSs is approximately 3334 percent, which is lower than the U.S. domestic

statutory federal tax rate primarily due to lower foreign tax rates applicable to foreign ~~earnings, partially offset by state income taxes.~~earnings.

~~Following~~ONGOING IRS MATTER

In connection with the merger with Plum Creek, we acquired equity interests in ~~first quarter~~Southern Diversified Timber, LLC, a timberland joint venture (Timberland Venture) with an affiliate of Campbell Global LLC (TCG Member). On August 31, 2016, ~~our income tax receivables~~the Timberland Venture redeemed TCG Member's interest and deferred income tax balances for our TRS have been adjusted to include Plum Creek’s TRS, which include $4 million in federal income tax receivables and $65 million in deferred income tax assets arising from temporary differences between the tax bases and book basesbecame a fully consolidated, wholly-owned subsidiary of ~~assets acquired and liabilities assumed in the merger. See~~ ~~Note 4: Merger with Plum Creekfor additional details.~~

~~ONGOING IRS MATTER~~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 REIT’s~~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 ~~the company~~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. ~~We expect that as~~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 – 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 and year-to-date period ended September 30, ~~2016,~~2017, compared to the quarter and year-to-date period ended September 30, ~~2015.~~2016.

Our merger with Plum Creek during first quarter 2016 significantly impacted the comparability of our consolidated operating results between 2016 and 2015. As a result of progress made to integrate financial processes and systems since the merger date, the results beginning on February 19, 2016, from acquired Plum Creek operations and the respective impacts of these results on our current period results are impracticable to disclose in the quarter and year-to-date period ended September 30, 2016. Our prior period results do not include pre-merger results of Plum Creek operations.

~~When compared to historical Plum Creek results, the post-merger results of the acquired operations are significantly impacted by the following items:~~


•	~~Increased depletion charges and increased basis of real estate sold as a result of applying acquisition accounting to Timber and timberlands assets acquired as described in~~ ~~Note 4: Merger with Plum Creekand~~


•	~~Certain merger-related costs as described in~~ ~~Note 15: Charges for Integration and Restructuring, Closures and Asset Impairments~~.

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 ~~segments. As published~~segment, specifically the Western region, is also affected by export demand. Japanese housing starts are a key driver of export log demand in Japan.

In the first nine months of 2017, housing starts averaged 1.19 million total units on a seasonally adjusted annual basis according to the U.S. Census ~~Bureau,~~Bureau. Single family units accounted for 70 percent of total housing starts 2017 year to date. While total housing start growth has slowed in 2017, there has been a shift in construction from multifamily units which are down 8 percent year over year, to single family units, which have increased 9 percent over the same period. This shift to the more wood intensive single family construction has been positive for ~~2015 were 1.11 million units.~~wood product demand. We continue to expect improving U.S. housing starts and anticipate a level of approximately ~~1.18~~1.21 million units in ~~2016 as~~2017, a ~~result of~~3 percent increase compared to 2016. We attribute this continued improvement primarily to employment growth, improving consumer confidence and ~~continued~~ historically low mortgage rates. ~~In the first nine months of 2016, housing starts averaged 1.15 million total units on a seasonally adjusted annual basis according~~

According to the U.S. Census Bureau and single family units averaged 0.77 million as a seasonally adjusted annual rate. This is consistent with expectations for 7 percent to 8 percent year-over-year growth in housing starts. Repair and remodeling activity is also a driver of wood product demand. The Joint Center for Housing of Harvard University, ~~is projecting an increase in remodeling expenditures~~the Leading Indicator of ~~8.6~~Remodeling Activity (LIRA), has increased by 6.9 percent in ~~2016~~first half of 2017 and is expected to average just under 6.7 percent year over ~~2015.~~year for 2017.

U.S. wood product markets advanced in the first half of 2017, consistent with growth in homebuilding and remodeling segments, as described above. According to Forest Economic Advisors, LLC (FEA), North American lumber consumption is expected to grow at a 4 to 5 percent rate in 2017. Consistent with this expectation, demand for logs increased with wood products production within our Western region. This coupled with higher market prices in third quarter 2017 drove higher realizations within this region. In the South, log supplies kept pace with increased demand, leaving prices flat to slightly down year-to-date.

Log inventories in Chinese ports have been stable through September 2017 as reported by International Wood Markets China Bulletin. Log and lumber demand in China remain strong due to higher construction activity. In Japan, housing starts for January through August 2017 are up 1 percent from the same period last year.

We expect demand from China and Japan in 2017 to be similar to modestly improved from demand experienced in 2016.

Our Real Estate, ~~& ENR~~Energy and Natural Resources segment is affected by the health of the U.S. economy and especially the U.S. housing sector ~~which influences~~of the ~~real estate market.~~economy. According to the Realtors Land Institute of the National Association of Realtors, ~~land transaction~~ prices and volumes of rural timber properties sold in 2016 grew 5 percent over 2015 sales. Additionally, sales of these types of properties are expected to ~~be the same or stronger~~grow 3 percent in ~~2016~~2017 when compared to ~~2015.~~2016.

SOFTWOOD LUMBER AGREEMENT

We operate a total of 19 softwood lumber mills with a total capacity of 4.9 billion board feet. Three of these mills are located in Canada, produce approximately 900 million board feet annually, and sell products in Canada, Asia, and the U.S.

On April 24, 2017, the U.S. Department of Commerce announced a preliminary determination that it would implement countervailing duties on Canadian softwood lumber shipments to the U.S. The rate applicable to Weyerhaeuser is 19.88 percent and became effective as of April 28, 2017. The U.S. Department of Commerce also announced that retroactive deposits at the 19.88 percent rate will be collected from certain Canadian lumber producers, including Weyerhaeuser, for ~~logs~~softwood lumber shipments from ~~our Timberlands segment is affected by production levels of wood-based building products.~~Canada to the U.S. ~~wood product markets advanced in~~during the ~~first nine months of 2016, consistent with homebuilding and remodeling segments and helped by a rising single family share of total housing starts. Single family starts are up 10 percent year~~90-day period prior to ~~date over the same period last year~~April 28, 2017.

The preliminary countervailing duties were suspended on a seasonally adjusted basis. Demand for logs increased with wood products production, and log supplies kept pace, leaving prices relatively flat year to date for western and southern sawlogs and southern pulpwood. Our western holdings are also affected by export demand. Log inventories in Chinese ports were lower in 2016 thanAugust 26, 2017, at which time we effectively stopped accruing for the ~~same period in 2015 and demand was modestly improved over 2015. Japan housing starts for January through August 2016 are up 5 percent from~~expense. The suspension of the ~~same period~~countervailing duties will last ~~year. Housing starts are a key driver~~until the US International Trade Commission reaches its final determination of ~~wood product and log demand in Japan. We expect demand from China and Japan in 2016~~injury, which is expected to be ~~similar to 2015.~~in December of this year.

On June 26, 2017, the U.S. Department of Commerce announced a preliminary determination that it would implement anti-dumping duties on Canadian softwood lumber shipments to the U.S. The rate applicable to Weyerhaeuser is 6.87 percent and became effective as of June 30, 2017. The U.S. Department of Commerce also announced that retroactive deposits at the 6.87 percent rate will be collected from certain Canadian lumber producers, including Weyerhaeuser, for softwood lumber shipments from Canada to the U.S. during the 90-day period prior to June 30, 2017.

Year-to-date 2017, we recorded an expense of approximately $9 million in our Wood Products segment related to the retroactive countervailing and antidumping duties. We have also expensed prospective duties as incurred, which as of September 30, 2017 totaled $7 million. As of

September 30, 2017, we have expensed a total of $5 million quarter-to-date 2017 and $16 million year-to-date 2017 for retroactive and prospective duties combined.

Comparing Third Quarter ~~2016~~2017 with Third Quarter ~~2015~~2016

Net sales

Net sales increased ~~$354~~$163 million – 2610 percent – primarily attributable to the following factors:

~~Timberlands segment~~Wood Products sales to unaffiliated customers increased ~~$174~~$122 million – 56 percent – due to higher delivered logs sales volumes primarily attributable to acquired Plum Creek operations. This increase was partially offset by lower average sales realizations. The decrease in average sales realizations is primarily attributable to the increase in sales volume for the South, which has lower average sales realizations compared to the West. The South comprised 33 percent of net sales for the quarter compared with 21 percent of net sales for third quarter 2015.

~~Real Estate & ENR segment sales increased $26 million – 118~~10 percent – primarily due to increased average sales realizations across all product lines, as well as, increased sales volumes within our engineered solid section and engineered I-joists product lines. Additionally, upon completion of the sales of our former Cellulose Fibers businesses, chips previously sold to Cellulose Fibers are now sales to unaffiliated customers.

Real Estate & ENR sales to unaffiliated buyers increased $34 million – 71 percent – primarily attributable to a $33 million increase in net real estate sales. This is attributable to increases in volume of ~~timberland~~ acres sold, ~~and increased ENR sales volume attributable to the operations acquired in our merger with Plum Creek,~~ partially offset by a decrease in average price realized per ~~timberland~~ acre.

Timberlands sales to unaffiliated customers increased $7 million – 1 percent – primarily attributable to an increase in Western Timberlands average sales realizations for delivered logs. These increases were partially offset by decreased Southern average sales realizations and decreased Northern delivered log sales volumes.

Costs of products sold

Costs of products sold increased $46 million – 3 percent – primarily attributable to the following:

Intercompany eliminations of costs of products sold decreased $54 million, therefore increasing consolidated cost of products sold. This reduction in intercompany costs of products sold is primarily due to the completion of the sales of our former Cellulose Fibers businesses. Chips and logs previously sold to Cellulose Fibers are now sales to unaffiliated customers and therefore have related cost of products sold.

Wood Products segment costs of products sold increased $25 million – 3 percent – primarily due to an increase in log and manufacturing costs, offset by a decrease in sales volume.

Real Estate & ENR segment costs of products sold increased $5 million – 19 percent – attributable to higher sales volumes and higher basis of real estate sold.

These increases to costs of products sold were offset by decreased Timberlands segment costs of products sold, which decreased $42 million –8 percent – primarily due to decreases in sales volumes and reduced silvicultural activities due to weather.

Operating income

Operating income decreased $56 million – 21 percent – primarily attributable to "Charges for product remediation" – $190 million. Refer to Note 16: Charges for Product Remediationfor further information. Excluding this charge, operating income increased $134 million, which is primarily due to increased gross margin, as explained above.

Net earnings attributable to Weyerhaeuser common shareholders

Our Net earnings attributable to Weyerhaeuser common shareholders decreased $97 million – 43 percent. Excluding 2016 "Earnings from discontinued operations, net of tax," net earnings attributable to Weyerhaeuser common shareholders decreased $32 million. This is attributable to decreased operating income, as described above, and:

a $29 million increase in expense related to "Non-operating pension and other postretirement benefit (costs) credits" due to a decrease in the expected return on our plan assets and an increase in the amortization of actuarial losses.

an $8 million decrease in "Equity earnings from joint ventures." This is attributable to equity earnings from our Timberland Venture, which effective August 31, 2016, is consolidated as a wholly-owned subsidiary.

These are partially offset by:


•	a decrease in "Interest expense, net of capitalized interest" – $16 million. Refer to Interest Expense for further detail.


•	a change from an income tax expense in third quarter 2016 to an income tax benefit in third quarter 2017 – $49 million. Refer to Income Taxes for further information.

"Earnings from discontinued operations, net of tax," decreased $65 million as all discontinued operations were sold in 2016.

Comparing Year-to-Date 2017 with Year-to-Date 2016

Net sales

Net sales increased ~~$154~~$604 million – 1513 percent – primarily attributable to the following factors:

Wood Products sales to unaffiliated customers increased $443 million – 13 percent – primarily due to increased ~~medium density fiberboard~~average sales ~~generated from~~realizations within our ~~operations acquired from our merger with Plum Creek; increased~~ oriented strand board and structural lumber product lines. Additionally, upon completion of the sales of our former Cellulose Fibers businesses, chips previously sold to Cellulose Fibers are now sales to unaffiliated customers.

Timberlands sales to unaffiliated customers increased $104 million – 8 percent – primarily due to an increase in Southern and ~~plywood average~~Other (primarily Twin Creeks) delivered log sales ~~realizations; and~~volumes. In addition to the increased ~~lumber and plywood~~ sales volumes, Timberlands net sales also increased due to increased recreational lease revenue.

Real Estate & ENR sales to unaffiliated buyers increased $56 million – 45 percent – primarily due to increased net real estate sales attributable to increases in volume of acres sold. Additionally, our net energy and natural resources sales increased, attributable to the operations acquired in our merger with Plum Creek.

Costs of products sold

Costs of products sold increased ~~$241~~$280 million – 228 percent – primarily attributable to the following:

~~Timberlands segment~~Intercompany eliminations of costs of products sold ~~increased $161~~decreased $147 million, ~~primarily due to:~~


◦	~~increased sales volumes as described above and higher depletion rates in the South and West for acquired Plum Creek timberlands, which were measured at fair value as of the merger date; and~~


◦	~~increased silviculture and reforestation costs, which is attributable to the significant increase in our timberlands holdings resulting from the merger;~~

~~Real Estate & ENR segment~~therefore increasing consolidated cost of products. This reduction in intercompany costs of products sold ~~increased $23 million~~is primarily due to ~~increased real estate~~the completion of the sales of our former Cellulose Fibers businesses. Chips and ~~ENR~~logs previously sold to Cellulose Fibers are now sales ~~volume as explained above, coupled with an increase in the average basis~~to unaffiliated customers and therefore have related cost of ~~real estate sold attributable to measuring acquired Plum Creek land at fair value in acquisition accounting; and~~products sold.

Wood Products segment costs of products sold increased ~~$66~~$134 million – 5 percent – primarily due to ~~increased sales volume as described above. This~~an increase ~~is partially offset by lower resin~~in log and manufacturing costs, ~~per unit.~~offset by a decrease in sales volume.

These increases to costs of products sold were offset by decreased Timberlands segment costs of products sold, which decreased $15 million – 1 percent – primarily due to continued focus on merger synergies and operational excellence as well as lower sales volumes in the West.

Operating income

Operating income increased ~~$108~~$7 million – 651 percent – primarily attributable to increased ~~net sales~~gross margin, as described above, and ~~costs of products sold explained above.~~

decreased "General and administrative expenses" – $15 million. These ~~increases~~ were ~~partially~~ offset by by:


•	increased "Charges for product remediation" – $240 million. Refer to Note 16: Charges for Product Remediation for further detail.

a ~~$14~~$58 million increase ~~to charges for integration and restructuring, closures and asset impairments, which is attributable to integration costs~~in expense related to ~~our merger with Plum Creek.~~"Other operating costs (income), net." This is primarily due to:


◦	a decrease in gains on disposition of non-strategic assets, primarily attributable to a $36 million pretax gain recognized in the first quarter of 2016 on the sale of our Federal Way, Washington headquarters campus.


◦	a decrease in foreign exchange gains – $11 million – primarily related to debt held by our Canadian entity.


◦	Refer to Note 17: Other Operating Costs (Income), net for further information.

•

increased "Charges for integration and restructuring, closures and asset impairments" – $37 million. This is attributable to a $147 million noncash impairment charge recognized during second quarter 2017 in relation to the company agreeing to sell its Uruguayan operations. This was partially offset by a $112 million decrease in charges related to our merger with Plum Creek. Refer to Note 15: Charges for Integration and Restructuring, Closures and Asset Impairments for further information.

Net earnings attributable to Weyerhaeuser common shareholders

Our Net earnings attributable to Weyerhaeuser common shareholders decreased $143 million – 31 percent. Excluding 2016 "Earnings from discontinued operations, net of tax," net earnings attributable to Weyerhaeuser common shareholders ~~increased $47~~decreased $20 million, ~~– 26 percent. Excluding~~primarily attributable to:

an $83 million increase in expense related to "Non-operating pension and other postretirement benefit (costs) credits" due to a decrease in the expected return on plan assets and an increase in the amortization of actuarial losses.

a $20 million decrease in "Equity earnings from ~~discontinued operations, net of tax, net earnings~~joint ventures." This is attributable to ~~Weyerhaeuser common shareholders increased $41 million – 34 percent – primarily attributable to the variances in net sales, costs of products sold and operating income~~equity earnings from our Timberland Venture, which effective August 31, 2016, is consolidated as ~~explained above. The increase is~~a wholly-owned subsidiary.

These decreases were partially offset ~~by a $66 million increase in income taxes from continuing operations attributable to:~~by:

~~increased earnings for our TRS due primarily to the improved performance of our Wood Products segment and~~

~~exhaustion of our remaining federal tax credit and net operating loss carryforwards during 2016.~~


•	a $33 million decrease in income tax expense. Refer to Income Taxes for further information.


•	a decrease in "Interest expense, net of capitalized interest" – $26 million. Refer to Interest Expense for further detail.


•	a decrease in "Dividends on preference shares" – $22 million. On July 1, 2016, all outstanding Preference Shares converted to Weyerhaeuser common shares. Refer to Note 5: Net Earnings Per Share and Share Repurchases for further information.

"Earnings from discontinued operations, net of tax," decreased $6$123 million ~~– 10 percent – primarily due to:~~

~~lower average sales realizations and sales volumes for pulp and liquid packaging board; and~~

~~increased charges for restructuring, closures and asset impairments, which consists of costs related to our strategic evaluation of the Cellulose Fibers businesses and transaction-related costs.~~

~~These~~as all discontinued operations were ~~partially offset by:~~

~~lower costs of products sold, primarily due to lower sales and ceasing depreciation when Cellulose Fibers manufacturing assets were classified as held-for-sale in the second quarter 2016;~~

~~lower equity loss from our printing papers joint venture; and~~

~~the net gain on the divestiture of liquid packaging board recognized in third quarter 2016.~~

~~Comparing Year-to-Date 2016 with Year-to-Date 2015~~

~~Net sales~~

~~Net sales increased $789 million – 20 percent – attributable to:~~

Timberlands segment sales increased $381 million – 40 percent – primarily due to acquired Plum Creek operations. This increase was partially offset by lower average sales realizations. The decrease in average sales realizations is primarily attributable to the increase in sales volume for the South, which has lower average sales realizations compared to the West. The South comprised 31 percent of net sales for year-to-date 2016 compared with 19 percent of net sales for the 2015 year-to-date period.

Real Estate & ENR segment sales increased $56 million – 81 percent – attributable to increased volume of timberland acres sold and increased ENR sales volume attributable to the operations acquired in our merger with Plum Creek, and an increase in average price realized per acre sold.

Wood Products segment sales increased $352 million – 12 percent – primarily due to increased medium density fiberboard sales generated from our operations acquired from our merger with Plum Creek; increased oriented strand board and plywood average sales realizations; and increased lumber, oriented strand board, plywood, and engineered solid section sales volumes.

~~Costs of products sold~~

~~Costs of products sold increased $538 million – 17 percent – primarily attributable to the following:~~

Timberlands segment costs of products sold increased $351 million, primarily due to increased sales volumes, as explained above and to higher depletion rates in the South and West for acquired Plum Creek timberlands, which were measured at fair value;

~~Real Estate & ENR segment costs of products sold increased $50 million attributable to increased real estate and ENR sales volumes as explained above; and~~

Wood Products segment costs of products sold increased $153 million primarily due to increased sales volume as explained above. This increase was partially offset by lower log, resin, and manufacturing costs per unit.

~~Operating income~~

~~Operating income increased $169 million – 33 percent – primarily due to the following:~~

~~increased gross margin as described above – $251 million,~~

~~noncash gain on foreign exchange debt held by our Canadian entity – $53 million, and~~

~~a pretax gain related to the sale of our Federal Way headquarters campus – $36 million.~~

~~These increases were partially offset by:~~

~~a $125 million~~ ~~increase in charges for integration and restructuring, closures and asset impairments, primarily attributable to~~ ~~2016 integration costs related to our merger with Plum Creek – $132 million; and~~

~~a $64 million increase in general and administrative expenses attributable primarily to acquired Plum Creek operations.~~

~~These increases are partially offset by a noncash impairment charge recognized in first quarter 2015 related to a nonstrategic asset that was~~ sold in ~~second quarter 2015 – $13 million.~~

~~Net earnings attributable to Weyerhaeuser common shareholders~~

Our net earnings attributable to Weyerhaeuser common shareholders increased $51 million – 13 percent. Excluding earnings from discontinued operations, net of tax, net earnings attributable to Weyerhaeuser common shareholders increased $39 million – 13 percent – primarily attributable to the variances in net sales, costs of products sold and operating income as explained above, partially offset by $100 million increase in income taxes from continuing operations resulting from increased taxable earnings generated by our TRS.

~~Earnings from discontinued operations, net of tax, increased $12 million – 11 percent – primarily due to:~~

~~lower costs of products sold, primarily due to lower sales and ceasing depreciation when Cellulose Fibers manufacturing assets were classified as held-for-sale in the second quarter 2016,~~

~~a decrease in the equity loss from our printing papers joint venture, and~~

~~the gain on the divestiture of the liquid packaging board business recognized in third quarter of~~ 2016.

~~These were partially offset by:~~

~~lower average sales realizations for pulp and liquid packaging board and lower sales volumes for liquid packaging board,~~

~~increased income tax expense due to the gain on the divestiture of the liquid packaging board business, and~~

increased charges for integration and restructuring, closures and asset impairments, which consists of costs related to our strategic evaluation of the Cellulose Fibers businesses and transaction-related costs.

TIMBERLANDS

Compared to 2015, the changes to the results of operations for our Timberlands segment are primarily attributable to the addition of approximately 6.3 million acres of Plum Creek timberlands, which produced over 18 million tons of harvest volumes in 2015. The merger results in expansion of our Southern timberlands from 4.0 million acres to 7.4 million acres – an 85 percent increase – and our Western timberlands from 2.6 million acres to 3.0 million acres – a 15 percent increase. The merger also added 2.5 million acres across West Virginia, Maine, New Hampshire, Vermont, Michigan, Wisconsin and Montana, which we refer to as our Northern timberlands. Increases to our sales volumes are primarily attributable to the significant increases in the size of our timberlands holdings by region, particularly in the South and North regions.

The composition of our sales volume by region was also altered by the merger, as the South and North regions, which have lower average sales realizations compared to the West, now comprise a greater portion of our overall sales. Additionally, within the South the acquired timberlands alter the overall sales mix, as lower realization pulpwood sales have increased and higher realization grade logs have decreased as a percentage of total sales, resulting in lower average sales realizations overall for the region.

~~As a result of of applying acquisition accounting to Timber and timberlands assets acquired as described in~~ ~~Note 4: Merger with Plum Creek~~, depletion rates have increased significantly in 2016 compared to 2015. When combined with increased sales volumes, these higher depletion rates drive the significant increases in our costs of products sold in 2016 compared to 2015 for the periods presented.

Comparing Third Quarter ~~2016~~2017 with Third Quarter ~~2015~~2016

Net sales – unaffiliated customers

Net sales to unaffiliated customers increased ~~$174~~$7 million – 561 percent – primarily due to:


•	a $6 million increase in Other delivered logs, primarily attributable to increases in delivered logs sales volumes from the Twin Creeks Venture (refer to Note 7: Related Parties for further information regarding our Twin Creeks Venture).

a ~~$96~~$4 million increase in Western log sales, primarily attributable to a 18 percent increase in average sales realizations for delivered logs. This increase was partially offset by a 14 percent decrease in delivered log sales volumes.

a $4 million increase in "Other" sales, primarily attributable to increased chip sales in Canada, which we previously sold to our former Cellulose Fibers segment and were intersegment sales during the third quarter 2016.

These increases were partially offset by:

a $5 million decrease in Southern log sales as a result of a ~~166~~3 percent ~~increase~~decrease in average sales realizations.

a $4 million decrease in Northern log sales, primarily attributable to a 15 percent decrease in delivered logs sales volumes ~~primarily attributable to acquired Plum Creek operations, partially offset by a 6 percent decrease in average sales realizations for delivered logs;~~

~~a $29 million increase in Northern log sales attributable to the operations added in our merger with Plum Creek; and~~

a $21 million increase in Western log sales as result of an 11 percent increase in delivered logs sales volumes primarily attributable to acquired Plum Creek operations and to more favorable fire season harvest conditions compared to third quarter 2015.

Intersegment sales

Intersegment sales ~~increased $6~~decreased $37 million – 317 percent – ~~primarily~~ due to increased intersegment sales in the United States – $11 million. This is attributable to higher intersegment log sales volumes attributable to the Montana operations acquired from Plum Creek, as well as an increase in average sales realizations. The increase in the United States was partially offset by a decrease in ~~Canada~~chip and log intersegment sales, ~~– $5 million – primarily attributable~~which were previously sold to ~~lower log sales volumes.~~our Cellulose Fibers business segment.

Costs of products sold

Costs of products sold ~~increased $161~~decreased $42 million – 408 percent – primarily due to a 903 percent ~~increase~~decrease in sales volumes attributable to the operations acquired in our merger with Plum Creek and to higher depletion rates in the South and West for acquired Plum Creek timberlands, which were measured at fair value as of the merger date. Silviculture costs also increased as a result of the increased timberlands acreage.volumes.

Operating income and Net contribution to earnings

Operating income and Net contribution to earnings increased ~~$15~~$9 million – 147 percent – primarily attributable to the changes in net sales and costs of products sold as explained above. The increase in gross margin was partially offset by higher selling, general, and administrative expenses due to our integration with Plum Creek.

~~Comparing Year-to-Date 2016 with Year-to-Date 2015~~

~~Net sales – unaffiliated customers~~

~~Net sales to unaffiliated customers increased $381 million – 40 percent – primarily due to:~~

a $235 million increase in Southern log sales as a result of a 141 percent increase in delivered logs sales volumes primarily attributable to adding acquired Plum Creek operations, partially offset by a 4 percent decrease in average sales realizations of delivered logs due to mix of sawlogs and pulp logs;

~~a $61 million increase in Northern log sales, which were acquired upon our merger with Plum Creek; and~~

a $37 million increase in Western log sales as a result of an 8 percent increase in delivered logs sales volumes primarily attributable to adding acquired Plum Creek operations, partially offset by a 2 percent decrease in average sales realizations for delivered logs.

~~Intersegment sales~~

Intersegment sales increased $6 million – 1 percent – primarily due to increased intersegment sales in the United States – $20 million. This is attributable to higher intersegment log sales volumes attributable to the Montana operations acquired from Plum Creek, as well as an increase in average sales realizations. The increase in the United States was partially offset by a decrease in Canada intersegment sales – $14 million. This decrease is

~~attributable to lower log sales volumes and average log sales realizations, partially offset by higher chip sales volumes.~~

~~Costs of products sold~~

Costs of products sold increased $351 million – 30 percent – primarily due to a 69 percent increase in sales volumes attributable to the operations acquired in our merger with Plum Creek and to higher depletion rates in the South and West for acquired Plum Creek timberlands, which were measured at fair value as of the merger date.

~~Operating income and Net contribution to earnings~~

~~Operating income and Net contribution to earnings increased $13 million – 4 percent – primarily attributable~~ to the changes in net sales and costs of products sold as explained above.

Comparing Year-to-Date 2017 with Year-to-Date 2016

Net sales - unaffiliated customers

Net sales to unaffiliated customers increased $104 million – 8 percent – primarily due to:

a $36 million increase in Southern log sales, primarily attributable to a 12 percent increase in delivered log sales volumes. This increase was partially offset by a 3 percent decrease in average sales realizations.


•	a $23 million increase in Other delivered logs primarily attributable to increases in delivered logs sales volumes from the Twin Creeks Venture (refer to Note 7: Related Parties for further information regarding our Twin Creeks Venture).

a $9 million increase in Western log sales, attributable to a 10 percent increase in average sales realizations. This increase was partially offset by a 7 percent decrease in delivered log sales volumes.

a $7 million increase in Northern log sales, attributable to a 13 percent increase in delivered log sales volumes. This increase was partially offset by a 1 percent decrease in average sales realizations.

Intersegment sales

Intersegment sales decreased $87 million – 14 percent – due to a decrease in chip and log intersegment sales, which were previously sold to our Cellulose Fibers business segment.

Costs of products sold

Costs of products sold decreased $15 million – 1 percent – primarily due to a 7 percent decrease in sales volumes.

Operating income and Net contribution to earnings

Operating income and Net contribution to earnings decreased $109 million – 29 percent – primarily attributable to the $147 million noncash pretax impairment charge recognized in relation to the Uruguayan sale agreement (refer toNote 3: Discontinued Operations and Other Divestitures). The impairment charge was partially offset by the changes in net sales and costs of products sold as explained 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 (especially for conservation sales). In any period the average sales price per acre will vary based on the location and physical characteristics of parcels sold.

Land added as a result of our merger with Plum Creek generally carries a higher per acre cost basis compared to our other acreage as a result of measuring acquired land at fair value in acquisition accounting. As a result, our costs of products sold will vary period-to-period based on the sales mix of acquired Plum Creek acres versus acres owned by Weyerhaeuser prior to the merger.

Comparing Third Quarter ~~2016~~2017 with Third Quarter ~~2015~~2016

Upon our merger with Plum Creek, we acquired five manufacturing facilities in Montana. The sales and net contribution to earnings of these facilities beginning on the merger date of February 19, 2016, are included in the

~~results of our Wood Products segment. The results of the two acquired plywood facilities are reported in softwood plywood and the two acquired lumber facilities are reported in structural lumber.~~

The Medium Density Fiberboard (MDF) facility supplies high-quality MDF to a wide range of customers throughout North America. Some of the more common uses for our MDF include furniture and cabinet components, architectural moldings, doors, store fixtures, core material for hardwood plywood, face material for softwood plywood, commercial wall paneling and substrate for laminate flooring.

We permanently closed two of the five acquired Plum Creek mills, the lumber facility and softwood plywood facility in Columbia Falls, Montana, during the third quarter of 2016. The closure of these facilities will allow us to align the available log supply with our manufacturing capacity, including adding shifts at our Kalispell, Montana facilities, to position our Montana operations for long-term success.

Net cash provided by our operations ~~increased $150~~decreased $39 million, primarily due to:

~~increased cash flows from our business segments of $370 million; and~~

~~a decrease in cash paid for income taxes of $30 million.~~

~~These increases were partially offset by:~~

decreased operating cash flows from discontinued operations of ~~$56 million;~~$192 million and

an increase in cash paid for ~~interest~~income taxes of ~~$77 million corresponding with our increased average indebtedness; and~~$155 million.

~~cash payments made in 2016 related to the Plum Creek merger of $85 million. Cash payments for merger-related costs were comprised of:~~


◦	~~investment banking and other professional services fees – $6 million;~~


◦	~~termination benefits – $33 million;~~


◦	~~settlement of Value Management Awards – $5 million;~~


◦	~~pension and postretirement benefits – $37 million; and~~


◦	~~other merger-related costs – $4 million.~~

These decreases were offset by increased cash flows from our business segments of $347 million. See Performance Measures for our Adjusted EBITDA by segment.

~~For additional information on long-term debt instruments assumed, see~~Refer to ~~Notes to Consolidated Financial Statements -~~ Note 10: Long-Term Debt and Lines of Credit. for further information.

Concurrent with the merger, Weyerhaeuser repaid in full the outstanding balances of Plum Creek's Revolving Line of Credit and Term Loan using $720 million of cash on hand. There were no payments of debt in 2015.

~~In the next 12 months $1,981 million of long-term debt is scheduled to mature, including the Term Loan Credit Facilities discussed below.~~

~~Term Loan Credit Facilities~~

In February 2016, Weyerhaeuser Company entered into a $600 million 18-month senior unsecured term loan maturing in August 2017. As of September 30, 2016, we had $600 million outstanding under this facility.

In March 2016, Weyerhaeuser Company entered into a $1.9 billion 18-month senior unsecured term loan maturing in September 2017. As of September 30, 2016, we had $1.1 billion outstanding under this facility.

Debt Covenants

Option Exercises

We received cash proceeds from the exercise of stock options of:

$89 million in 2017; and

$48 million in ~~year-to-date 2016 and~~

~~$29 million in year-to-date 2015.~~2016.

Our average stock price was $33.01 and $29.74 for year-to-date 2017 and ~~$32.18 in year-to-date~~ 2016, ~~and 2015,~~ respectively.

Paying Dividends and Repurchasing Stock

We paid cash dividends on common shares of:

$699 million in 2017; and

$700 million in ~~year-to-date 2016 and~~

~~$460 million in year-to-date 2015.~~2016.

The ~~increase~~slight decrease in dividends paid is due ~~in part~~ to ~~an increase in our quarterly~~decreased common shares outstanding at the dividend ~~from $0.29 to $0.31 per share in the third quarter of 2015 and in part to an increase in total shares outstanding.~~record dates.

We repurchased 9,775,873 shares of common stock for $306 million (including transaction fees) during third quarter 2016 and 67,816,810 shares for $2.0 billion (including transaction fees) during year-to-date 2016 under the 2016 Share Repurchase Authorization. The 2016 Share Repurchase Authorization was approved in November 2015 by our Board of Directors and authorized management to repurchase up to $2.5 billion of outstanding ~~shares subsequent to the closing of our merger with Plum Creek. This new authorization replaced the August 2015 share~~shares. During third quarter 2017, we did not repurchase authorization.

As of September 30, ~~2016,~~2017, we had remaining authorization of $500 million for future stock repurchases.

We record share repurchases upon the trade date as opposed to the settlement date when cash is disbursed. We record a liability ~~to account~~ for repurchases that have not been cash settled. There were no unsettled repurchases as of September 30, ~~2016 or December 31, 2015.~~2017.

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. Due to recent organizational changes and our February 19, 2016 merger with Plum Creek, effective for 2016, we have revised our definition of Adjusted EBITDA to add back the basis of real estate sold. We have revised our prior-period presentation to conform to our current reporting.

Adjusted EBITDA, as we define it, is operating income from continuing operations adjusted for depreciation, depletion, amortization, basis of real estate sold, unallocated pension ~~and postretirement~~service costs ~~not allocated to business segments (primarily interest cost, expected return on plan assets, amortization of actuarial loss and amortization of prior service cost/credit),~~ and special items. Adjusted EBITDA excludes results from joint ventures.

CRITICAL ACCOUNTING POLICIES

~~Our~~There have been no significant changes during third quarter 2017 to our critical accounting policies ~~are discussed~~presented in our ~~2015~~2016 Annual Report on Form 10-K. As a result of the impact to our financial statements from our merger with Plum Creek, we now consider the following accounting policies to be critical accounting policies. The following are information updates, and should be read in conjunction with, the critical accounting policies disclosed in our 2015 Annual Report on Form 10-K.

~~Timber Depletion~~

~~We record depletion – the costs attributed to timber harvested – as trees are harvested.~~

~~To calculate our depletion rate, which is updated annually, we:~~

~~take the total carrying cost of the timber and~~

~~divide by the total timber volume estimated to be harvested during the harvest cycle.~~

~~Estimating the volume of timber available for harvest over the harvest cycle requires the consideration of the following factors:~~

~~effects of fertilizer and pesticide applications,~~

~~changes in environmental regulations and other regulatory restrictions,~~

~~limits on harvesting certain timberlands,~~

~~changes in harvest plans,~~

~~scientific advancement in seedling and growing technology; and~~

~~changes in weather patterns.~~

~~In addition, the duration of the harvest cycle varies by geographic region and species of timber.~~

~~Depletion rate calculations do not include estimates for:~~

~~future silviculture or sustainable forest management costs associated with existing stands,~~

~~future reforestation costs associated with a stand’s final harvest; and~~

~~future volume in connection with the replanting of a stand subsequent to its final harvest.~~

~~A 5 percent decrease in our estimate of future harvest volumes would have:~~

~~increased depletion expense by $4 million for third quarter 2016 and $10 million for year-to-date 2016; and~~

~~increased depletion expense by $1 million for third quarter 2015 and $5 million for year-to-date 2015.~~

~~Business Combinations~~

We recognize identifiable assets acquired and liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions for the purchase price allocation process to value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to any goodwill previously recorded (or to earnings in the event that no goodwill was previously recorded) to the extent that we identify adjustments to the preliminary purchase price allocation. Beginning January 1, 2016, we have adopted ASU 2015-16, which eliminates the requirement to retrospectively apply measurement period adjustments to the preliminary purchase price allocation and revise comparative information on the income statement and balance sheet for any prior periods affected. We will recognize measurement period adjustments and any resulting effect on earnings during the period in which the adjustment is identified. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our condensed consolidated statements of operations.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

LONG-TERM INDEBTEDNESS OBLIGATIONS

The following summary of our long-term indebtedness obligations includes:

~~all future cash obligations arising from our long-term indebtedness;~~

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.
