NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
FOR THE QUARTERS AND YEAR-TO-DATE ENDED SEPTEMBER 30, 2015MARCH 31, 2016 AND 20142015

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 can betaxes on REIT taxable income that is distributed to shareholders without first paying corporate level tax, substantially eliminating the double taxation on income. A significant portion of our timberland segment earnings receives this favorable tax treatment.shareholders. We are however, subject to corporate taxes on built-in-gains (the excess of fair market value over tax basis at January 1, 2010) on sales of real property (other than standing timber) held by the REIT during the first 10 years following the REIT conversion. We continue to be required to pay federal corporate income taxes on earnings of our Taxable REIT Subsidiary (TRS), which principally includes our manufacturing businesses and the portion of our Timberlands segmentand Real Estate and Energy & Natural Resources (Real Estate & ENR) segments' income included in the TRS.

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 March 31, 2016 (see Note 3: 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, and noncontrolling interests are presented within equity.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”“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 disclosures normally provided in accordance with accounting principles generally accepted in the United States have been omitted. These 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, 2014.2015. Results of operations for interim periods should not 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 20152016 reporting. This makes year-to-year comparisons easier. Our reclassifications had no effect on consolidated net earnings or equity. Our reclassifications present

As a result of the results of operations discontinued in 2014 separately onmerger, we have revised our Consolidated Statement of Operations and inbusiness segments. Results for fiscal periods prior to first quarter 2016 have been revised to conform to the related footnotes.new segments. Note 3: Discontinued Operations2: Business Segments provides information about our discontinued operations.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, the FASB issued ASU 2015-14, which deferred the effective date of ASU 2014-09 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. We plan to adopt thethese accounting standard updates on January 1, 2018 and may use either the retrospective or cumulative effect transition method. We are evaluating the impact that ASU 2014-09 will have

6



on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor determined the effect of the standard onto our ongoing financial reporting.

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 startingbeginning after December 15, 2015 and early adoption is permitted.2015. We expect to adopt ASU 2015-03adopted on January 1, 2016 and have determined that its adoption will not have a material impact onreclassified balances of debt issuance costs accordingly in our consolidated financial statementsbalance sheet and in related disclosures at that time.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 our pension plan. The new guidance is effective retrospectively for fiscal periods starting after December 15, 2015 and early adoption is permitted. We have not yet determined an adoption date.2015. This new guidance eliminatesremoves the requirement to categorize certain pension investments inwithin the fair value hierarchy.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 will beare presented separately from the fair value hierarchy and reconciled to total investments in our consolidated financial statements and related 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 andor 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 ASU 2015-11 on January 1, 2017 and are evaluating the 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. We expect it to impact our consolidated financial statements and disclosures related to accounting for our merger with Plum Creek in future interim periods, in the event that measurement period adjustments are recorded.

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 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 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 first quarter of 2015 of $10 million were retrospectively reclassified from an operating activity to a financing activity in the statement of cash flows.


NOTE 2: BUSINESS SEGMENTS

Reportable business segments are determined based on the company’s management approach. The management approach, as defined by FASB ASC 280, “Segment Reporting,” 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 the first quarter of 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, beginning in fiscal year 2016, the company will report its financial performance based on four reportable business segments: Timberlands, Real Estate & ENR, Wood Products, and Cellulose Fibers. Prior to revising our segment structure, activities related to the Real Estate & ENR business segment were reported as part of the Timberlands business segment. All prior period amounts 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, and manufacturing, distributing, and selling products made from trees. Our principaltrees, as well as maximizing the value of every acre we own through the sale of higher and better use (HBU) properties and monetizing reserves of minerals, oil, gas, coal, and other natural resources on our timberlands. The following is a brief description of each of our reportable business segments are:and activities:
Timberlands – which includes logs, timber, minerals, oil and gas, and international wood products;our Uruguay operations;
Real Estate & ENR – which includes equity interests in our Real Estate Development Ventures (as defined and described in Note 6: Equity Method Investments), sales of HBU and non-core timberlands, minerals, oil, gas, coal and other natural resources;
Wood Products – which includes softwood lumber, engineered wood products, structural panelsoriented strand board, plywood, medium density fiberboard and building materials distribution; and
Cellulose Fibers – which includes pulp, liquid packaging board and an equity interest in aour newsprint jointand publishing papers venture.
We divested
On November 8, 2015, Weyerhaeuser Real Estate Company (WRECO)announced that the board authorized the exploration of strategic alternatives for its Cellulose Fibers business segment. The Board indicated that it intended to consider a broad range of alternatives including, but not limited to, continuing to hold and operate the business or a sale or spin-off of the business. On May 1, 2016, we entered into a transaction agreement to sell our Cellulose Fibers pulp mills to International Paper for $2.2 billion in July 2014cash. The deal includes five pulp mills and that entitytwo modified fiber mills. The transaction with International Paper does not include our liquid packaging board facility or newsprint and publishing papers venture. The Company’s review of those assets is excluded from the segment results below. See Note 3: Discontinued Operations for information regarding our discontinued operations.ongoing.

7


As of March 31, 2016, the assets and liabilities of the Cellulose Fibers business, including those related to the pulp mills, had not met the criteria to be classified as held for sale under the requirements of ASC Topic 360, primarily because the board of directors was still considering a variety of strategic alternatives at that time. Accordingly, the results from these operations are classified as continuing operations in our Consolidated Statement of Operations for the period ended March 31, 2016.

We expect the transaction with International Paper to close in fourth quarter 2016.

NOTE 3: 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 the 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 higher and better use land values across the combined portfolio.

Under the merger agreement, each issued $450and 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 are fully vested and relate to services rendered to Plum Creek prior to the merger, the replacement stock options are 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 are not included in consideration transferred. See additional details about replacement share-based payment awards in Note 14: Share-based Compensation.

The company recognized approximately $110 million and $14 million of unsecuredmerger-related costs that were expensed during the first quarter of 2016 and unsubordinated senior obligations bearing an interest ratethe full year of 4.375 percent due June 15, 20192015, respectively. See Note 15: Charges for Integration and $450Restructuring, 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.

No non-recurring merger-related costs were incurred during the first quarter of 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 unsubordinated senior obligations bearing an interest ratehas applied the acquisition method of 5.875 percent due June 15, 2024, whichaccounting. Under the acquisition method, the assets acquired and liabilities assumed by Weyerhaeuser from Plum Creek were transferred along with other WRECOrecorded as of the date of the acquisition at their respective estimated fair values.

Our March 31, 2016 consolidated balance sheet includes the assets and liabilities of Plum Creek, which have been measured at fair value as part of the merger date. The fair values of the assets acquired and liabilities assumed were preliminarily determined using the income, cost and 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 and Real Estate Divestiture.Development Ventures, and the note payable to the Timberland Venture. The net proceeds after deductingincome approach estimates fair value for an asset based on the discount were $887 million.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.



Preliminary estimated fair values of identifiable assets acquired and liabilities assumed as of the acquisition date are as follows:

We are currently in the process of finalizing our valuations related to the following:
timber and timberlands,
minerals and mineral rights,
property and equipment,
acquired equity method investments, 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 4:NET EARNINGS PER SHARE AND SHARE REPURCHASES

NET EARNINGS PER SHARE

Our basic earnings per share attributable to Weyerhaeuser shareholders were:
$0.35 during third quarter and $0.78 during year-to-date 2015; and
$2.17 during third quarter and $2.85 during year-to-date 2014.
Our diluted earnings per share attributable to Weyerhaeuser shareholders were:
$0.350.11 during thirdfirst quarter and $0.77 during year-to-date 2015;2016; and
$2.150.17 during thirdfirst quarter and $2.83 during year-to-date 2014.2015.

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:
the weighted average number of our outstanding common shares and
the effect of our outstanding dilutive potential common shares.shares:
Dilutive potential common shares can include:
outstanding stock options,

We use the treasury stock method to calculate the 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.

We use the if-converted method to calculate the effect of our outstanding preference shares. In applying the if-converted method, conversion is not assumed for purposes of computing diluted earnings per share if the effect would be antidilutive. Preference shares are antidilutive whenever the amount of the dividend declared in or accumulated for the current period per common share obtainable on conversion exceeds diluted earnings per share exclusive of the preference shares.

Preference shares are evaluated for participation on a quarterly basis to determine whether two-class presentation is required. Preference shares are considered to be participating as of the financial reporting period end to the extent they would participate in dividends paid to common shareholders. Preference shares are not considered participating for the quarter and year-to-date periods ended September 30, 2015.March 31, 2016. Under the provisions of the two-class method, basic and diluted earnings per share would be presented for both preference and common shareholders.

SHARES EXCLUDED FROM DILUTIVE EFFECTPotential 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.

LIFO – the last-in, first-out method – applies to major inventory products held at our U.S. domestic locations. We began to use the LIFO method for domestic products in the 1940s as required to conform with the tax method elected. Subsequent acquisitions of entities added new products under the FIFO - the first-in, first-out method – or moving average cost methods that have continued under those methods. The FIFO or moving average cost methods applies to the balance of our domestic raw material and product inventories as well as for all material and supply inventories and all foreign inventories. If we used FIFO for all inventories, our stated inventories would have been higher by $120$123 million as of September 30, 2015March 31, 2016 and $124 millionas of December 31, 2014.2015.

EQUITY METHOD INVESTMENTS ACQUIRED THROUGH OUR MERGER WITH PLUM CREEK

Through our merger with Plum Creek on February 19, 2016, we acquired equity interests in the Real Estate Development Ventures and the Timberland Venture. Additionally, through the merger Weyerhaeuser assumed the benefits and obligations associated with the formation of Twin Creeks Timber, LLC a timberland joint venture (Twin Creeks Venture). The Twin Creeks Venture was funded with initial capital contributions on April 1, 2016.

Real Estate Development Ventures

WestRock-Charleston Land Partners, LLC (WR-CLP) is a limited liability company which holds 21,000 acres of residential and commercial real estate development properties, currently under development (Class A Properties) and 51,000 acres of high-value development lands (Class B Properties) (referred to collectively as the Real Estate Development Ventures). We have a 3% interest in Class A Properties and a 50% interest in Class B Properties. WestRock Company is the other member of WR-CLP and owns 97% of the Class A Properties and 50% of the Class B Properties. The Company uses the equity method of accounting for both its Class A and Class B interests. Our share of the equity earnings are included in the net contribution to earnings of our Real Estate & ENR segment.

Timberland Venture

We hold a preferred and common interest in Southern Diversified Timber, LLC, a timberland joint venture (Timberland Venture), which includes 100% of the preferred interests and 9% of the common interests. The Timberland Venture’s other member, an affiliate of Campbell Global LLC, holds 91% of the Timberland Venture’s common interests. The activities of the Timberland Venture consist primarily of owning timberlands and entering into cutting contracts with an affiliate of Campbell Global for the selling and harvesting of timber. An affiliate of Campbell Global is the manager of the Timberland Venture. Our investment in and share of the equity earnings of the Timberland Venture is not attributed to one of our business segments, and is reported as an Unallocated Item.

The preferred interest is entitled to a cumulative preferred return equal to 7.875% per annum. No distributions can be made on the common interests until all current period and prior period preferred returns have been paid. Both our preferred and common interests are accounted for based on the equity method of accounting. Equity earnings of the Timberland Venture are first allocated to our preferred interest to the extent of our preferred return, with any excess earnings allocated among the common interests based on ownership percentage. All of the equity earnings will be allocated to our preferred interest in years in which our preferred return equals or exceeds the earnings of


the Timberland Venture. To the extent of shortfall in equity earnings (cumulative preferred return in excess of allocated equity earnings), future years’ excess earnings will be allocated to our preferred interest until the cumulative shortfall is eliminated.

The Timberland Venture can be liquidated at any time with the consent of both members. From October 1, 2017 to March 31, 2018 Weyerhaeuser has the sole right to redeem our interest in the Timberland Venture. The other member has a similar redemption right until June 30, 2016. Upon liquidation or redemption, the members’ interests will be adjusted to reflect the fair value of the Timberland Venture’s net assets. The adjustment would first be allocated to our preferred interest to the extent that any accumulated shortfall in net income attributable to our preferred interest exists, but only to the extent that the fair value of the net assets of the Timberland Venture exceed book basis.

Twin Creeks Venture

Prior to our merger, Plum Creek entered into an agreement with third party institutional investors to form the Twin Creeks Venture. Weyerhaeuser assumed the benefits and obligations associated with the Twin Creeks Venture in connection with our merger with Plum Creek. Our initial contribution to the Twin Creeks Venture was made on April 1, 2016. Weyerhaeuser contributed approximately 260,000 acres of timberlands in exchange for a 21% ownership interest and cash of $440 million. The other partners contributed total cash of $440 million for a 79% ownership interest. Our transactions and related activities with Twin Creeks will be reported within our Timberlands business segment.

ASSUMED PLANS FROM MERGER WITH PLUM CREEK

Upon our merger with Plum Creek, we assumed one qualified pension plan and two non-qualified pension plans. All active participants in these plans became fully vested and the plans were frozen as of February 19, 2016. The 2014 loss due to curtailment and special termination benefits arecumulative 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 involuntary terminations caused by restructuring activities, as well as the Real Estate Divestiture.

non-qualified plans are held in a grantor trust and are subject to the claims of creditors in the event of bankruptcy. As a
During fourth quarter 2013, we decided to eliminate post-Medicare health funding for certain salaried retirees after 2014. We recognized a pretax gain of $23 million in third quarter 2014result, these are not considered plan assets and $113 million in year-to-date 2014 from this plan amendment. This gain ishave not been netted against the non-qualified pension liability. These assets are included in "Other operating income, net"assets" in ourConsolidated Statement of OperationsBalance Sheet and reflected in the amortization of prior service credit in the table above..

VALUATIONDuring the first quarter, we recognized $5 million of pension benefit costs from change in control provisions for certain Plum Creek executives. These enhanced pension benefits were triggered by changes in control and retention decisions made after the completion of the merger (see Note 15: Charges for Integration and Restructuring, Closures and Impairments).

FAIR VALUE OF PENSION AND OTHER POSTRETIREMENT BENEFIT PLANSPLAN 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 revised the year-end estimated fair value of pension plan assets to incorporate year-end net asset values reflected
As disclosed in financial statements received after we have filed our Annual Report on Form 10-K. During10-K for the year ended December 31, 2015, the value reported for our pension plan assets at the end of 2015 was estimated. Additional information regarding the year-end values generally becomes available to us during the first half of the following year. We expect to complete the valuation of our pension plan assets during second quarter 2015, we recorded an increase2016. The final adjustments could affect net pension periodic benefit cost.

Consistent with accounting for the merger as the acquirer in a business combination (see Note 3: Merger with Plum Creek), pension assets and benefit obligations were remeasured to reflect their fair value as of the date of the acquisition. 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 thethese items as of February 19, 2016 were as follows:

$137 million qualified pension plan assets of $57
$149 million or 1 percent. We also revised our census data that is used to estimate ourqualified pension plan projected benefit obligation for
$50 million non-qualified pension and other postretirement benefit plans. As a result of that update, during second quarter 2015, we recorded an increase to theplan projected benefit obligation of $25 million, or less than 1 percent. The net effect was a $32 million increase in the funded status.

EXPECTED CONTRIBUTIONS AND BENEFIT PAYMENTS
We do not anticipate making a contribution to our U.S. qualified pension plan for 2015.
In 20152016 we expect to:
be required to contribute approximately $38$16 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$19 millionfor our U.S. nonqualified pension plans; and;
make benefit payments of $25$52 million for our U.S. nonqualified pension plans, including $33 million of benefit payments for plans assumed from Plum Creek to be paid out of assets held in grantor trusts; and
make benefit payments of $22 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.


NOTE 8: VARIABLE INTEREST ENTITIES

See our Annual Report on Form 10-K for the year ended December 31, 2015 for information regarding Weyerhaeuser's special-purpose entities.

As a result of the acquisition of Plum Creek, we acquired interests in certain joint ventures as described in Note 6: Equity Method Investmentsthat are variable interest entities.

REAL ESTATE DEVELOPMENT VENTURES

WestRock-Charleston Land Partners, LLC (WR-CLP) is a variable interest entity. WR-CLP 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. The company has committed to make additional capital calls of up to $29 million during the years 2016 to 2020. The company does not intend to provide any additional sources of financing for WR-CLP.

Weyerhaeuser is 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 $87 million, the carrying amount of our investment in WR-CLP at March 31, 2016, plus required future capital contributions we make.

TIMBERLAND VENTURE

The Timberland Venture is a variable interest entity. Aside from quarterly interest payments on the Note Payable to Timberland Venture, the company has not provided financing or other support to the venture. The venture generates sufficient cash from operating activities to finance its operations.

We are not the primary beneficiary of the Timberland Venture. The company does not manage the day-to-day operations of the Timberland Venture, has only limited protective rights and its involvement is generally limited to receiving distributions on its preferred and common interests. We are not the primary beneficiary because we do not direct the activities that most significantly impact the Timberland Venture’s economic performance. We believe that the activities that most significantly impact the Timberland Venture’s economic performance include managing the timberlands along with the timing and extent of the harvesting activities, neither of which we control.

Our maximum exposure to loss is $852 million, the carrying amount of the investment at March 31, 2016. Generally, losses are first allocated among the common interests based on positive capital accounts in which we hold a 9% common interest. Losses would be allocated to our preferred interest only when losses have reduced capital accounts comprising the common interests to zero.

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, Weyerhaeuser 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, 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.

Senior Notes

The assumed Senior Notes are publicly traded and were issued by Plum Creek Timberlands, L.P. (PC Timberlands) and are fully and unconditionally guaranteed by Weyerhaeuser Company as of the acquisition date. See Note 18: Condensed Consolidating Financial Information for issuer and guarantor financial information. There were two separate issuances of Senior Notes: $569 million (principal) of 4.70% notes which matures in 2021 and $325 million (principal) of 3.25% notes which matures 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% notes and $324 million for the 3.25% 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 reduce the carrying values of the notes to the principal amounts at maturity.

Installment Note

We have 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 in the farm credit system. The annual interest rate on the Installment Note is fixed at 5.207%. 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.

The company receives 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 $892 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 have assumed a promissory note payable to Timberland Venture (Note Payable to Timberland Venture) that has a principal balance of $783 million. The annual interest rate on the Note Payable to Timberland Venture is fixed at 7.375%. 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 the election of Weyerhaeuser. 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 $837 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.

The Timberland Venture is a related party, as described in Note 6: Equity Method Investments.



NEW TERM LOANS ISSUED

During February 2016 and subsequent to completion of the Plum Creek merger, we entered into a $600 million 18-month senior unsecured term loan maturing in August 2017. Borrowings are currently at LIBOR plus 1.05%. As of March 31, 2016 we had $600 million outstanding under this facility.

During March 2016, we entered into a $1.9 billion 18-month senior unsecured term loan maturing in September 2017. Borrowings are currently at LIBOR plus 1.05%. At March 31, 2016, we had $500 million outstanding under this facility.

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 fair value of the Note Payable to Timberland Venture is estimated using a market approach based on quoted market prices we received for comparable issues of debt.

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,
carrying short-term investments at expected net realizable value, and
the allowance for doubtful accounts.

NOTE 9:12: 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: Income Taxes for a discussion of a tax proceeding involving the company and its consolidated subsidiaries.

ENVIRONMENTAL MATTERS

Our environmental matters include:
site remediation and
asset retirement obligations.

Site Remediation

Under the Comprehensive Environmental Response Compensation and Liability Act – 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 the EPA to negotiate an administrative order on consent for a contaminant removal action for a portion of the site comprising a stretch of the river approximately 1.7 miles long that the EPA refers 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 expect to jointly implement the administrative order. At this time we do not expect to incur material losses related to the implementation of the administrative order.

As of September 30, 2015,March 31, 2016, our total accrual for future estimated remediation costs on the active Superfund sites and other sites for which we are responsible was approximately $39 million.$37 million. These reserves are recorded in "Accrued liabilities" and "Other liabilities" in 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, 2015,March 31, 2016, our total accrualaccrued balance for these obligations was $34$38 million. These obligations are recorded in "Accrued liabilities" and "Other liabilities" in our Consolidated Balance Sheet. The accruals have not changed materially since the end of 2015.

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.

NOTE 11:14: SHARE-BASED COMPENSATION

In year-to-date 2015,first quarter 2016, we granted 2,122,6086,121,835 stock options, 433,4691,954,796 restricted stock units 238,662(RSUs), 428,794 performance share units (PSUs) and 58,373106,752 stock appreciation rights. In addition, 364,576947,628 outstanding restricted stock unitsRSUs and 241,734268,197 outstanding performance share unitsPSUs vested during year-to-date 2015.first quarter 2016. A total of 1,784,3401,033,647 shares of common stock were issued as a result of restricted stock unitRSU vesting, performance share unitPSU vesting and stock option exercises.

SHARE-BASED COMPENSATION RESULTING FROM OUR MERGER WITH PLUM CREEK

Included in the award activity above are replacement awards granted as a result of the merger with Plum Creek. Eligible outstanding Plum Creek stock options, restricted stock unit and deferred stock unit awards were converted into equivalent equity awards with respect to Weyerhaeuser Common Shares, after giving effect to the appropriate adjustments to reflect the consummation of the merger. In total, we issued replacement awards consisting of 1,953,128 stock options and 1,248,006 RSUs. We also assumed 289,910 value management awards (VMAs) through the merger with Plum Creek.



Replacement Stock Option Awards

The replacement stock option awards issued as a result of the merger with Plum Creek have similar exercise provisions as the terms of Weyerhaeuser current awards. All replacement stock option awards were fully vested prior to the date of the merger, so no expense will be recorded by Weyerhaeuser. 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 3: 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 the first quarter resulted in accelerated vesting of 501,135 of the replacement RSUs and recognition of $14 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 VMAs assumed by Weyerhaeuser were valued at target. All outstanding VMAs, if earned, will vest December 31, 2017 and be paid in the first quarter of 2018. The VMAs are classified and accounted for as liabilities, as they will be cash settled 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 will result in acceleration of vesting and expense recognition in the period that the qualifying termination occurs. Qualifying terminations during the first quarter resulted in $5 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
The
Excluding replacement awards granted as a result of the merger, the weighted average exercise price of all of the stock options granted to date in 20152016 was $35.41.$23.09. The vesting and post-termination vesting terms for stock options granted to date in 20152016 were as follows:
vest ratably over four years;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 is forfeitedforfeits 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
stop vesting for all other situations including early retirement prior to age 62.

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 the first quarter 2015, we recognized a noncash impairment charge of $13 million in first quarter related to a nonstrategic asset held in Unallocated Items that was sold in second quarter.Items. The fair value of the asset was determined using significant unobservable inputs (level 3) based on discounted cash flow model. During 2014, our restructuring and closure charges were primarily related to our selling, general and administrative cost reduction initiative to support achieving our competitive performance goals.

Foreign exchange losses (gains) result from changes in exchange rates, on transactions, primarily related to our Canadian operations.
Land management income includes income from recreational activities, land permits, grazing rights, firewood sales and other miscellaneous income related to land management activities.

NOTE 14:17: INCOME TAXES
As a REIT, we generally are not subject to federal corporate level taxincome taxes on REIT taxable income of the REIT that is distributed to shareholders. We are however, subject to corporate taxes on built-in-gains (the excess of fair market value over tax basis at January 1, 2010) on sales of real property (other than standing timber) held by the REIT during the first 10 years following the REIT conversion. We continue to be required to pay federal corporate income taxes on earnings of our TRS, which includes our manufacturing businesses and the portion of our Timberlands segmentand Real Estate & ENR segments' income included in the TRS.

The 2015quarterly provision for income taxes is based on the current estimate of the annual effective tax rate. Our 20152016 estimated annual effective tax rate for our TRS is approximately 2432 percent,, which is lower than the U.S. domestic statutory federal tax rate primarily due to favorable permanent tax deductions and lower foreign tax rates applicable to foreign earnings, partially offset by state income taxes.

Following the merger with Plum Creek in the first quarter 2016, our income tax receivables 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 $59 million in deferred income tax assets arising from temporary differences between the tax bases and book bases of assets acquired and liabilities assumed in the merger. See Note 3: Merger with Plum Creekfor additional details.

ONGOING IRS MATTER

As of March 31, 2016, Plum Creek's 2008 federal REIT income tax return is being audited by the Internal Revenue Service (“IRS”). The IRS has proposed an adjustment to Plum Creek REIT's U.S. federal income tax treatment of the Timberland Venture formation transaction, which occurred on October 1, 2008, on the basis that the transfer of the timberlands to Southern Diversified Timber, LLC, was a taxable transaction to the company at the time of the transfer rather than a nontaxable capital contribution to the Timberland Venture. The company has filed a protest with IRS Appeals. Based on recent discussions with IRS Appeals, we do not expect to reach a resolution and plan to file a petition in the U.S. Tax Court.

If the IRS's position is upheld on judicial appeal, it could result in a maximum built-in gains tax liability of approximately $100 million. In addition, we could be required to accelerate the distribution to shareholders of up to $600 million of gain from the transaction. We expect that as much as 80% of any such 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. We would also be required to pay interest on the undistributed gain, which would be substantial, and, if applicable, penalties.



We believe the transfer of the timberlands was a nontaxable contribution to the Timberland Venture and not a taxable transaction. We have not accrued income taxes for financial reporting purposes with respect to this matter. We are confident in our position and believe that the proposed re-characterization of the Timberland Venture formation transaction by the IRS will ultimately be unsuccessful. We intend to vigorously contest this re-characterization.

We base our forward-looking statements on a number of factors, including the expected effect of:
the economy,
laws and regulations,
adverse litigation outcomes and the adequacy of reserves,
changes in accounting principles,
contributions to pension plans,
projected benefit payments,
projected tax treatment, rates and credits, and
other related matters.

You should understand that it is not possible to predict or identify all such factors and, consequently, you should not consider any such list to be a complete set of all potential risks or uncertainties. Should other risks or uncertainties materialize, or should our underlying assumptions prove inaccurate, actual results could differ materially from past results as well as from our estimated or projected results.


19




RISKS, UNCERTAINTIES AND ASSUMPTIONS

Major risks and uncertainties – and assumptions that we make – that affect our business and may cause actual results to differ from these forward-looking statements include, but are not limited to:
the effect of general economic conditions, including employment rates, interest rate levels, housing starts, availability of financing for home mortgages and strength of the U.S. dollar;
market demand for our products, including market demand for our timberland properties with higher and better uses, which is related to, among other factors, the strength of the various U.S. business segments and U.S. and international economic conditions;
performance of our manufacturing operations, including maintenance requirements;
potential disruptions in our manufacturing operations;
the level of competition from domestic and foreign producers;
raw material availability and prices;
the effect of weather;
the risk of loss from fires, floods, windstorms, hurricanes, pest infestation and other natural disasters;
energy prices;
the successful execution of our internal plans and strategic initiatives;
the successful and timely execution and integration of our strategic acquisitions, including our ability to realize expected benefits and synergies, and the successful and timely execution of our strategic divestitures, each of which is subject to a number of risks and conditions beyond our control including, but not limited to, timing and required regulatory approvals;
transportation and labor availability and costs;
federal tax policies;policies, interpretations or rulings;
the effect of forestry, land use, environmental and other governmental regulations;
legal proceedings;
performance of pension fund investments and related derivatives;
the effect of timing of retirements and changes in the market price of our common stock on charges for share-based compensation;
changes in accounting principles; and
other factors described under “Risk Factors” in our 20142015 Annual Report on Form 10-K.10-K and in our Registration Statement on Form S-4/A filed on December 23, 2015.

EXPORTING ISSUES

We are a large exporter, affected by:
economic activity in Europe and Asia, especially Japan and China;
currency exchange rates – particularly the relative value of the U.S. dollar, Canadian dollar, euro and yen; and
restrictions on international trade or tariffs imposed on imports.

RESULTS OF OPERATIONS

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

Sales realizations refer to net selling prices – this includes selling price plus freight, minus normal sales deductions.
Net contribution to earnings refers to earnings (loss) attributable to Weyerhaeuser shareholders before interest expense and income taxes.
In reviewing our results of operations, it is important to understand net sales and operating income included in Consolidated Results and individual segment discussions below exclude the results of discontinued operations. Refer to Note 3: Discontinued Operations.
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 periods ended September 30, 2015,March 31, 2016, compared to the quarter and year-to-date periods ended September 30, 2014.March 31, 2015.


ECONOMIC AND MARKET CONDITIONS AFFECTING OUR OPERATIONS

The strength of the U.S. housing market strongly affects our Wood Products and Timberlands segments. As published by the U.S. Census Bureau, total housing starts for 20142015 were slightly above 1,000,0001.11 million units. We continue to expect improving U.S. housing starts and anticipate a level of approximately 1,100,0001.22 million units in 20152016 as a result of employment growth, improving consumer confidence and continued historically low mortgage rates. In Q1 of 2016 housing starts averaged 1.15million total units on a seasonally adjusted annual basis according to the U.S. Census Bureau and single family units averaged 0.79 million as a seasonally adjusted annual rate. This is consistent with expectations for 10% year-over-year growth in total 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 of 8.6% in 2016 over 2015.

Demand for logs from our Timberlands segment is affected by production levels of wood-based building products. US wood product markets advanced in Q1 2016 with rising housing starts and the start of the construction season, unlike Q1 2015 when severe winter weather limited activity. Demand for logs increased with wood products production and log prices were slightly higher in Q1 for western logs. Southern sawlogs were slightly lower in the quarter but pulpwood prices improved. Our Western holdings are also affected by export demand. The Lunar New Year holiday limited construction activity and log demand in the China market in Q1 while Japan saw a rise in housing starts in the first 2 months of 2016 versus year ago levels. Housing starts are a key driver of wood product and log demand in Japan. We expect demand from China and Japan in 20152016 to be lower than 2014.similar to 2015.

Cellulose Fibers is primarily affected by global supply and demand factors and the relative strength of the U.S. dollar. TheIn 2015 the euro declined in 2014 and early 2015 relative to the U.S. dollar to theits lowest level in recent years. In Q1 of 2016 the U.S. dollar/euro relationship stabilized, with the euro strengthening slightly (less than 1%) versus the U.S. dollar compared to Q4 2015. We do not expect the U.S. dollar to continue to strengthen significantly relative to developed currencies during the rest of 2015.2016.

Net sales decreased $95$18 million51 percent – primarily dueattributable to the following:
Timberlands segment sales decreased $38$8 million, primarily due to lower average export logrealizations on delivered logs;
Real Estate & ENR segment sales realizationsdecreased $16 million, primarily due to decreases in volume of acres sold and sales volumes in the West.price realized per acre; and
Cellulose Fibers segmentnet sales decreased $32$17 million, primarily due to decreased pulp and liquid packaging board average sales realizations partially offset by increased pulp and liquid packaging board sales volumes.
These decreases were offset by increased sales in our Wood Products segment – $23 million, primarily due to increased sales volumes across most product lines and increased sales realizations for oriented strand board and engineered solid sections.

Cost of products sold

Cost of products sold increased $90 million – 6 percent. Excluding $103 million of cost of products sold attributable to acquired Plum Creek operations, cost of products sold decreased $13 million, primarily attributable to the following:
Real Estate & ENR cost of products sold decreased $8 million, primarily due to a decrease in acreage sold;
Cellulose Fibers cost of products sold decreased $8 million, primarily due to lower average sales realizations for pulp and liquid packaging board,maintenance spending on scheduled outages and lower sales volumes for pulp. per unit chemical and energy costs in our pulp manufacturing business; and
Costs of products sold from Unallocated Items decreased $13 million primarily due to a decrease in elimination of intersegment profit in inventory and LIFO and lower pension expense.
These decreases were partially offset by the following:
Timberlands cost of products sold increased $6 million in the West, primarily due to higher sales volumes for liquid packaging board.operating costs from increased log purchases; and
Wood Products segment sales decreased $25products cost of products sold increased $5 million primarily due to lower averageincreased sales realizations for structural lumbervolumes in all product lines.

Operating income

Operating income decreased $14 million – 7 percent. Excluding $24 million of operating loss attributable to acquired Plum Creek operations, operating income increased $10 million – 5 percent primarily due to the following:
a pretax gain related to the sale of our Federal Way headquarters campus – $36 million; and oriented strand board (OSB).
gain on noncash foreign exchange on debt held by our Canadian entity – $42 million.



These decreasesincreases were partially offset by higher structural lumber, OSB, engineered solid section, and engineered I-joists shipment volumes, and higher sales from complementary building products.$67 million of charges related to the Plum Creek merger.

Net earnings attributable to Weyerhaeuser common shareholders

Our net earnings attributable to Weyerhaeuser common shareholders decreased $973$20 million – 8422 percent. Excluding $31 million of net losses attributable to acquired Plum Creek operations, net earnings increased $11 million – 12 percent – primarily dueattributable to the following:
earnings from discontinued operations recognized in 2014 – $966 million. There were no earnings from discontinued operations in 2015.
lower gross margin – $36 million – primarily due to lower averagenet sales, realizations in lumbercosts of products sold and OSB in our Wood Products segment and lower average log sales realizations and timberlands exchanges in our Timberlands segment, partially offset by decreased scheduled maintenance outage days in our Cellulose Fibers segment; and
lower other operating income – $44 million – primarily due to a $23 million pretax gain recognized in 2014 related to a previously announced postretirement plan amendment.
These decreases were partially offset by:
lower tax expense – $55 million – primarily due to lower earnings in our Taxable REIT Subsidiary (TRS); and
lower selling, general and administrative expenses – $14 million.explained above.

Here is a comparison
Net sales

Net sales increased $5 million – 15 percent. Excluding $21 million of net sales attributable to unaffiliated customersacquired Plum Creek operations, net sales decreased $16 million – 47 percent.

Net real estate sales decreased $14 million – 52 percent – attributable to decreases in volume of acres sold and price realized per acre for timberlands sales.

Net energy and natural resources sales decreased $2 million – 29 percent – primarily due to lower oil and natural gas prices.
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.

Cost of products sold

Cost of products sold increased $10 million – 100 percent. Excluding the $18 million of costs of products sold attributable to acquired Plum Creek operations, cost of products sold decreased $8 million – 80 percent – primarily due to a decrease in real estate acreage sold.

Operating income and Net contribution to earnings

Operating income and Net contribution to earnings for the quarter decreased $8 million – 35 percent. Excluding $2 million of operating income attributable to acquired Plum Creek operations, operating income decreased $10 million – 43 percent – attributable to net sales and costs of products sold explained above.

29On November 8, 2015, Weyerhaeuser announced that the board authorized the exploration of strategic alternatives for its Cellulose Fibers business segment. The Board indicated that it intended to consider a broad range of alternatives including, but not limited to, continuing to hold and operate the business or a sale or spin-off of the business. On May 1, 2016, we entered into a transaction agreement to sell our Cellulose Fibers pulp mills to International Paper for $2.2 billion in cash. The deal includes five pulp mills and two modified fiber mills. The transaction with International Paper does not include our liquid packaging board facility or newsprint and publishing papers venture. The Company’s review of those assets is ongoing.


As of March 31, 2016, the assets and liabilities of the Cellulose Fibers business, including those related to the pulp mills, had not met the criteria to be classified as held for sale under the requirements of ASC Topic 360, primarily because the board of directors was still considering a variety of strategic alternatives at that time. Accordingly, the results from these operations are classified as continuing operations in our Consolidated Statement of Operations for the period ended March 31, 2016.

We expect the transaction with International Paper to close in fourth quarter 2016.


UNALLOCATED ITEMS

Unallocated Itemsitems are chargesgains or gainscharges 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, andequity earnings from our Timberland Venture, the elimination of intersegment profit in inventory and the LIFO reserve.

$460 million in 2015 and
$411 million in 2014.

Repurchases of Common Stock
On August 13, 2014, our Board of Directors approved a stock repurchase program under which we are authorized to repurchase up to $700 million of outstanding shares (the 2014 Repurchase Program). We repurchased 3,258,148 shares of common stock for $90 million during third quarter 2015 and 15,442,231 shares of common stock for $496 million during year-to-date 2015. In total, we have repurchased 21,505,224 shares of common stock for $700 million under the 2014 Repurchase Program. All common stock purchases under the 2014 Repurchase Program have been made through open-market transactions.
On August 27, 2015, our Board of Directors approved a new share repurchase program of up to $500 million of outstanding shares (the 2015 Repurchase Program), commencing upon completion of the 2014 Repurchase Program.

Revolving Credit Facility

Weyerhaeuser Company has a $1 billion 5-year senior unsecured revolving credit facility that expires in September 2018. There were no net proceeds from the issuance of debt or from borrowings (repayments) under our available credit facility in year-to-date 2016 or 2015, and as of March 31, 2016, the entire $1 billion remained available for borrowing.

Assumed Debt and Debt Repayments

In connection with the merger with Plum Creek, Weyerhaeuser either assumed or 2014.repaid Plum Creek's outstanding long-term debt instruments. The long-term debt instruments assumed consisted of:
two issuances of publicly traded Senior Notes,
an Installment Note and
the Note Payable to Timberland Venture.

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

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.

There are no debt maturities in the next 12 months.

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 March 31, 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 March 31, 2016, we had $500 million outstanding under this facility.

Debt Covenants

As of September 30, 2015March 31, 2016, Weyerhaeuser Company was in compliance with all debt covenants. There have been no significant changes during year-to-datefirst quarter 2016 to the debt covenants presented in our 2015 toAnnual Report on Form 10-K for our existing long-term debt instruments. The debt covenants for the Senior Notes assumed through our merger with Plum Creek and the debt covenants for the new term loans issued in February 2016 and March 2016 do not differ materially from our debt covenants presented in our 20142015 Annual Report on Form 10-K.


33On April 28, 2016, the Installment Note Payable was amended to align the agreement's debt covenants with our term loans' covenants for determining compliance as of March 31, 2016. The assumed Note Payable to Timberland Venture does not include any material financial maintenance covenants.




When calculating compliance with financial debt covenants, we exclude the impact of our pension and other post-retirement plans recorded within cumulative other comprehensive income from adjusted shareholders' interest (equity). The excluded amounts are $1,417 million and $1,425 million and are equal to the cumulative actuarial losses and prior service costs for our pension and post-retirement plans at March 31, 2016 and December 31, 2015, respectively (see Notes to Consolidated Financial Statements - Note 13: Cumulative Other Comprehensive Income (Loss)).

Option Exercises

We received cash proceeds from the exercise of stock options of:
$4 million in 2016 and
$21 million in 2015.

Our average stock price was $26.70 and $35.01 in first quarter 2016 and 2015, respectively.

Paying Dividends and Repurchasing Stock

We paid cash dividends on common shares of:
$241 million in 2016 and
$152 million in 2015.

The increase in dividends paid is primarily due to an increase in our quarterly dividend from $0.29 to $0.31 per share and an increase in total shares outstanding.

During first quarter 2016, we repurchased 31,367,541 shares of common stock for $863 million (including transaction fees) 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 repurchase authorization. Transaction fees incurred for repurchases are not counted as use of funds authorized for repurchases under the 2016 Share Repurchase Authorization. All common stock purchases under the stock repurchase program were made in open-market transactions. As of March 31, 2016, we had remaining authorization of $1,638 million for future stock repurchases.

We record share repurchases upon 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. Unsettled repurchases consisted of 2,128,645 shares totaling $66 million as of March 31, 2016. There were no unsettled repurchases as of March 31, 2015, or December 31, 2015.

From April 1, 2016 to April 30, 2016 we repurchased 12,288,096 shares of common stock for $387 million under the 2016 Share Repurchase Authorization. As of April 30, 2016, we had remaining authorization of $1,251 million.


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 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 the quarter ended March 31, 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, pension and postretirement 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 and discontinued operations.items.

CRITICAL ACCOUNTING POLICIES
There have been no significant changes during year-to-date 2015 to our
Our critical accounting policies presentedare discussed in our 20142015 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% decrease in our estimate of future harvest volumes would have:

Increased depletion expense by $3 million for Q1 2016
Increased depletion expense by $2 million for Q1 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
No changes occurred during year-to-date 2015 that had a material effect
LONG-TERM INDEBTEDNESS OBLIGATIONS

The following summary of our long-term indebtedness obligations includes:
all future cash obligations arising from our long-term indebtedness, which includes obligations for the Note Payable to Timberland Venture;
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 information relating to quantitative and qualitative disclosures aboutdiscounted value of the future cash flows using market risk that was provided in the company’s Annual Report on Form 10-Kyields for the year ended Decembersame type and comparable issues of debt. Changes in market rates of interest affect the fair value of our fixed-rate debt.

CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

Disclosure controls are controls and other procedures that are designed to ensure that information required to be disclosed in the reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, to allow timely decisions regarding required disclosure. The company’s principal executive officer and principal financial officer have concluded that the company’s disclosure controls and procedures were effective as of September 30, 2015March 31, 2016, based on an evaluation of the company’s disclosure controls and procedures as of that date.

CHANGES IN INTERNAL CONTROLS

As a result of our February 2016 merger with Plum Creek, the company is implementing internal controls over significant processes specific to the acquisition that management believes are appropriate in consideration of related integration of operations, systems, control activities, and accounting for the merger and merger-related transactions. As of the date of this Quarterly Report on Form 10-Q, we are in the process of further integrating the acquired Plum Creek operations into our overall internal controls over financial reporting.

NoExcept as described above, no changes occurred in the company’s internal control over financial reporting during thirdfirst quarter 20152016 that have materially affected, or are reasonably likely to materially affect, the company’s internal control over financial reporting.


LEGAL PROCEEDINGS



RISK FACTORS

OurThere have been no material changes with respect to the risk factors are discusseddisclosed in our 20142015 Annual Report on Form 10-K. The following information updates, and should be read in conjunction with, the risk factors disclosed in our 2014 Annual Report on Form 10-K.


Regulation of Water
On June 29, 2015, the United States Environmental Protection Agency and Corps of Engineers adopted new regulations concerning the scope of the federal Clean Water Act that we believe broadens the agencies’ assertion of jurisdiction in certain respects. The new regulations could increase the number and scope of permits required for certain forestry-related activities and could result in additional costs. We are currently evaluating the potential impact of the new regulations on our operations. We do not expect that the new regulations will affect Weyerhaeuser differentially to other forest landowners. Several parties, including states and trade associations, have filed lawsuits in various federal courts seeking to invalidate and enjoin implementation of the new regulations. The outcome of that litigation is uncertain.
