NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

FOR THE QUARTERS AND YEAR-TO-DATE PERIODS ENDED SEPTEMBER 30, 2011 AND

2010

NOTE 1:BASIS OF PRESENTATION

We are a corporation that has elected to be taxed as a real estate investment trust (REIT). As a REIT, we expect to derive most of our REIT income from investments in timberlands, including the sale of standing timber through pay-as-cut sales contracts. REIT income can be 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. 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 also will continue to be required to pay federal corporate income taxes on earnings of our Taxable REIT Subsidiary (TRS), which principally includes our manufacturing businesses, our real estate development business and our non-qualified timberland segment income.

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

• 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 as a separate component of equity.

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.

We report our financial condition in two groups:

• Forest Products – our forest products-based operations, principally the growing and harvesting of timber, the manufacture, distribution and sale of forest products and corporate governance activities; and

• Real Estate – our real estate development and construction operations.

Throughout these Notes to Consolidated Financial Statements, unless specified otherwise, references to “Weyerhaeuser,” “we” and “our” refer to the consolidated company, including both Forest Products and Real Estate.

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, 2010.

RECLASSIFICATIONS

We have reclassified certain balances and results from the prior year to be consistent with our 2011 reporting. This makes year-to-year comparisons easier. Our reclassifications had no effect on net earnings or Weyerhaeuser shareholders’ interest. The reclassifications include changes to the way we classify certain transactions as operating, investing or financing on our Consolidated Statement of Cash Flows and to present the results of operations discontinued in 2011 separately on our Consolidated Statement of Operations. Note 3: Discontinued Operations provides information about our discontinued operations.

NOTE 2:ACCOUNTING PRONOUNCEMENTS

Disclosures about Employer's Participation in a Multiemployer Pension Plan

Accounting Standards Update (“ASU”) No. 2011-09 dealing with multiemployer pension plans was issued by the FASB in September 2011. The ASU takes effect in fourth quarter 2011 and requires quantitative and qualitative disclosure about:

• significant multiemployer plans in which an employer participates, including plan names and identifying number;

• level of an employer's participation in the plans, including the employer's contributions made to the plans and an indication of whether the employer's contributions represent more than five percent of the total contributions made to the plan by all contributing employers;

• financial health of the significant multiemployer plans, including an indication of the funded status, whether funding improvement plans are pending or implemented and whether the plan has imposed surcharges on the contributions to the plan; and

• nature of the employer commitments to the plan, including when the collective-bargaining agreements that require contributions to the plans are set to expire and whether those agreements require minimum contributions to be made to the plans.

We are currently evaluating the effect that the adoption of ASU No. 2011-09 will have on our disclosures.

NOTE 3:DISCONTINUED OPERATIONS

Our discontinued operations for the quarter and year-to-date periods ended September 30, 2011 and 2010 include our hardwoods and Westwood Shipping Lines operations. The following table summarizes the components of net sales and net earnings from discontinued operations.

Results of discontinued operations exclude certain general corporate overhead costs that have been allocated to and are included in contribution to earnings for the operating segments.

7

Other discontinued operations relate to current period gains or losses for businesses we have divested in prior years and are included in the Corporate and Other segment. During second quarter 2011 we increased our reserve for estimated future environmental remediation costs and recognized an $11 million charge associated with discontinued operations. See Note 14: Legal Proceedings, Commitments and Contingencies.

Our Consolidated Balance Sheet includes the following assets and liabilities of our hardwoods and Westwood Shipping Lines operations as of December 31, 2010.

SALE OF HARDWOODS

On August 1, 2011, we completed the sale of our hardwoods operations to American Industrial Partners for consideration of $109 million, of which $25 million is a note receivable. During second quarter 2011, we reduced our hardwoods assets to their fair value less selling costs which resulted in the recognition of a $9 million charge. An additional $10 million pension curtailment charge was recognized in third quarter 2011 when the transaction closed. Total pre-tax charges on the sale of $22 million were recorded in our Wood Products segment. We recognized a tax benefit on the sale of $8 million resulting in a year-to-date net loss of $14 million.

The following operating assets were included as part of the transaction:

• seven primary hardwood mills with a total capacity of 300 million board feet,

• four concentration yards,

• three remanufacturing plants,

• one log merchandising yard and

• sales offices in the U.S., Canada, Japan, China and Hong Kong.

SALE OF WESTWOOD SHIPPING LINES

On September 30, 2011, we completed the sale of Westwood Shipping Lines to J-WesCo of Japan for $58 million in cash. We recognized a pre-tax gain of $49 million in Corporate and Other and recorded tax expense of $18 million, resulting in a net gain of $31 million. This transaction also reduced our operating lease obligations as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2010 by approximately $130 million.

NOTE 4:BUSINESS SEGMENTS

We are principally engaged in the growing and harvesting of timber; the manufacture, distribution and sale of forest products; and real estate development and construction. Our principal business segments are:

• Timberlands – which includes logs; timber; minerals, oil and gas; and international wood products;

• Wood Products – which includes softwood lumber, engineered lumber, structural panels and building materials distribution;

• Cellulose Fibers – which includes pulp, liquid packaging board and an equity interest in a newsprint joint venture; and

• Real Estate – which includes real estate development, construction and sales.

We sold our hardwoods operations in a transaction that closed on August 1, 2011. The hardwoods results are included in our Wood Products segment and results of discontinued operations for all periods presented in this report.

Corporate and Other includes certain gains or charges that are not related to an individual operating segment and the portion of items such as share-based compensation, pension and postretirement costs, foreign exchange transaction gains and losses associated with financing and other general and administrative expenses that are not allocated to the business segments. Historically, Corporate and Other included the results of our transportation operations. This included our five short line railroads that were sold at the end of 2010 and Westwood Shipping Lines that was sold on September 30, 2011. Westwood results are included in our results of discontinued operations.

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

NOTE 5:NET EARNINGS PER SHARE

Our basic earnings per share attributable to Weyerhaeuser shareholders were:

• $0.29 during third quarter and $0.49 during year-to-date2011; and

• $3.52 during third quarter and $4.49 during year-to-date2010.

Our diluted earnings per share attributable to Weyerhaeuser shareholders were:

• $0.29 during third quarter and $0.49 during year-to-date2011; and

• $3.50 during third quarter and $4.48 during year-to-date2010.

10

Basic earnings per share is net earnings divided by the weighted average number of our outstanding common shares.

Diluted earnings per share is net earnings divided by the sum of the:

• weighted average number of our outstanding common shares and

• the effect of our outstanding dilutive potential common shares.

Dilutive potential common shares can include:

• outstanding stock options,

• restricted stock units and

• performance share units.

We use the treasury stock method to calculate the effect of our outstanding dilutive potential common shares. 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.

To implement our decision to be taxed as a REIT, we distributed our accumulated earnings and profits to our shareholders, determined under federal income tax provisions, as a “Special Dividend.” At the election of each shareholder, the Special Dividend was paid in cash or Weyerhaeuser common shares. The Special Dividend of $5.6 billion was paid September 1, 2010 and included approximately 324 million common shares. The stock portion of the Special Dividend was treated as the issuance of new shares for accounting purposes and affects our earnings per share only for periods after the distribution. Prior periods are not restated. The required treatment results in earnings per share that is less than would have been the case had the common shares not been issued. Reflected below are pro forma results giving effect to the common stock distribution for diluted earnings per common share for the quarter and year-to-date period ended September 30, 2010 as if the common stock distribution had occurred at the beginning of the period.

During 2011, performance share units were granted under our performance share plan. These are disclosed in the above table at the potential maximum amount of shares that may be issued, which is 150 percent of the granted shares. See Note 6: Share-Based Compensation for more information.

During third quarter 2011, we repurchased 1,199,800 shares of common stock for $20 million under the 2008 stock repurchase program. On August 11, 2011, our board of directors replaced the 2008 stock repurchase program and approved the 2011 stock repurchase program under which we are authorized to repurchase up to $250 million of outstanding shares. During third quarter 2011, we repurchased 589,824 shares of common stock for $9 million under the 2011 program. All common stock purchases under the programs were made in open-market transactions. As of September 30, 2011, we had remaining authorization of $241 million for future share repurchases.

NOTE 6:SHARE-BASED COMPENSATION

In 2011, we granted 1,941,686 stock options, 720,120 restricted stock units, 325,736 performance share units, and 52,869 stock appreciation rights. In addition, 283,557 outstanding restricted stock unit awards vested during year-to-date2011. A total of 2,710,962 shares of common stock were issued as a result of restricted stock unit vesting and stock option exercises.

STOCK OPTIONS

The weighted average exercise price of all of the stock options granted in 2011 was $24.16. The vesting and post-termination vesting terms for stock options granted in 2011 were as follows:

• options vest ratably over 4 years;

• options vest or continue to vest in the event of death, disability, or retirement at an age of at least 62;

• options continue vesting for one year in the event of involuntary termination when the retirement criteria for full or continued vesting have not been met; and

• options stop vesting for all other situations including early retirement prior to age 62.

Expected volatility	38.56		%
Expected dividends	2.48		%
Expected term (in years)	5.73
Risk-free rate	2.65		%
Weighted average grant date fair value	$	7.54

RESTRICTED STOCK UNITS

The weighted average fair value of the restricted stock units granted 2011 was $23.94. The vesting provisions for restricted stock units granted in 2011 were as follows:

• restricted stock units vest ratably over 4 years;

• restricted stock units immediately vest in the event of death while employed or disability;

• restricted stock units partially vest upon retirement at an age of at least 62 or job elimination depending on the employment period after grant date; and

• restricted stock units will be forfeited upon termination of employment in all other situations including early retirement prior to age 62.

12

PERFORMANCE SHARE UNITS

In 2011, as part of a new long-term incentive compensation strategy intended to tie executive compensation more closely to company performance, we granted a target number of performance share units to executives. Performance share units will be converted into shares of Weyerhaeuser stock – to the extent earned – at the end of a four-year timeframe that combines performance and market conditions with vesting requirements. The final number of shares awarded will range from 0 percent to 150 percent of each grant’s target, depending upon actual company performance.

The ultimate number of Performance Share Units earned is based on two measures:

• Weyerhaeuser’s cash flow during the first year and

• Weyerhaeuser’s relative total shareholder return (TSR) ranking in the S&P 500 during the first two years.

At the end of the performance period, performance share unit payouts would be in shares of our stock. Performance share units granted in 2011 and that are earned vest as follows:

• units vest 50 percent, 25 percent and 25 percent on the second, third and fourth anniversaries of the grant date, respectively, as long as the individual remains employed by the company;

• units fully vest in the event of death while employed or disability;

• units partially vest upon retirement at an age of at least 62 or job elimination depending on the employment period after grant date; and

• units will be forfeited upon termination of employment in all other situations including early retirement prior to age 62.

The weighted average grant date fair value of the performance share units was $25.35. Since the award contains a market condition, the effect of the market condition is reflected in the grant date fair value which is estimated using a Monte Carlo simulation model. This model estimates the TSR ranking of the company among the S&P 500 index over the 2 year performance period. Compensation expense is based on the estimated probable number of earned awards and recognized over the four-year vesting period on an accelerated basis. Generally, compensation expense would be reversed if the performance condition is not met unless the requisite service period has been achieved.

NOTE 7:CHARGES FOR RESTRUCTURING, CLOSURES AND ASSET IMPAIRMENTS

We review the carrying value of our assets whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Impairments typically occur when we make decisions to curtail, close, sell or restructure operations.

Charges for restructuring, closures and asset impairments for the quarters and year-to-date periods ended September 30, 2011 and 2010, include:

	QUARTER ENDED				YEAR-TO-DATE ENDED

Asset impairments in third quarter 2011 included $29 million of impairment charges in the Wood Products segment primarily related to the decision to permanently close four engineered lumber facilities that had been previously indefinitely closed. The fair values of the facilities were determined using significant unobservable inputs (Level 3) based on liquidation values.

Changes in accrued severance related to restructuring and facility closures during the year-to-date period ended September 30, 2011 were as follows:

The $152 million pretax gain on sale of non-strategic timberlands resulted from the sale of 82,000 acres in southwestern Washington.

Gain on disposal of assets in 2010 included pretax gains of $40 million from the sale of certain British Columbia forest licenses and associated rights.

Foreign exchange losses (gains) result from changes in exchange rates, primarily related to our Canadian operations.

Land management income consists primarily of income derived from leasing, renting and granting easement and rights of way on our timberlands.

NOTE 9:INVENTORIES

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, 2011				DECEMBER 31, 2010
DOLLAR AMOUNTS IN MILLIONS	CARRYING  VALUE		FAIR VALUE (LEVEL 2)		CARRYING  VALUE		FAIR VALUE (LEVEL 2)
Long-term debt (including current maturities):
Forest Products	$	4,192	$	4,496	$	4,710	$	5,029
Real Estate	$	318	$	326	$	350	$	360

To estimate the fair value of long-term debt, we used the following valuation approaches:

• market approach – based on quoted market prices 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.

The inputs to the 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.

At the beginning of June 2011, we exercised our right to call approximately $518 million of 6.75 percent notes due in 2012. We recognized a pretax charge in 2011 of $26 million, which included early retirement premiums, unamortized debt issuance costs and other miscellaneous charges in connection with the early extinguishment of debt. This charge is included in interest expense in the Consolidated Statement of Operations.

Real Estate debt maturities were $32 million during 2011.

FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS

We believe that our other financial instruments, including cash, short-term investments, 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 12:PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

The components of net periodic benefit costs (credits) are:

Loss due to curtailment and special termination benefits includes charges of $11 million related to the sale of our hardwoods and Westwood Shipping Lines operations in third quarter 2011. These charges are included in our results of discontinued operations.

FAIR VALUE OF PENSION PLAN ASSETS

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. When the differences are significant, we revise the year-end estimated fair value of pension plan assets to incorporate year-end net asset values reflected in audited financial statements received after we have filed our annual report on Form 10-K. Based on the final valuations as of December 31, 2010, the fair value of pension assets increased in second quarter 2011 by $138 million, or 2.9 percent. Based on this information we recorded the following adjustments during second quarter 2011:

• $20 million increase in the pension asset;

• $86 million decrease in the liability for deferred pension;

• $38 million increase in the liability for deferred income taxes; and

• $68 million net decrease in cumulative other comprehensive loss, which resulted in an increase in total Weyerhaeuser shareholders' interest.

17

EXPECTED CONTRIBUTIONS AND BENEFIT PAYMENTS

During 2011 we expect to:

• be required to contribute approximately $83 million to our Canadian registered and nonregistered pension plans;

• contribute $19 million to our U.S. nonqualified pension plans and have no required contribution to the U.S. qualified plan; and

• make benefit payments of $44 million to our U.S. and Canadian other postretirement plans.

NOTE 14:LEGAL PROCEEDINGS, COMMITMENTS AND CONTINGENCIES

This note provides details about our:

• legal proceedings and

• environmental matters.

18

LEGAL PROCEEDINGS

We are party to legal matters generally incidental to our business. The ultimate outcome of any legal proceeding:

• is subject to a great many variables and

• cannot be predicted with any degree of certainty.

However, whenever probable losses from litigation could reasonably be determined – we believe that we have established adequate reserves. In addition, we believe the ultimate outcome of the legal proceedings:

• could have a material adverse effect on our results of operations, cash flows or financial position in any given quarter or year; but

• will not have a material adverse effect on our long-term results of operations, cash flows or financial position.

Current Year Claim

On April 25, 2011, a complaint was filed in the United States District Court for the Western District of Washington on behalf of a person alleged to be a participant in the company’s U.S. Retirement Plan for salaried employees. The complaint alleges violations of the Employee Retirement Security Act (ERISA) with respect to the management of the plan’s assets and seeks certification as a class action. The company believes that its pension plans have been consistently managed in full compliance with established fiduciary standards and is vigorously contesting the claim. The company has filed a motion to dismiss the claim.

ENVIRONMENTAL MATTERS

Our environmental matters include:

• site remediation,

• asset retirement obligations,

• regulation of air emissions in the U.S. and

• regulation of water in the U.S.

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.

As of September 30, 2011, our total accrual for future estimated remediation costs on the active Superfund sites and other sites for which we are responsible was $36 million. This includes an $11 million increase to the reserve that was accrued in second quarter 2011 and is included in our results from discontinued operations.

We change our accrual to reflect:

• new information on any site concerning implementation of remediation alternatives,

• updates on prior cost estimates and new sites and

• costs incurred to remediate sites.

We believe it is reasonably possible – based on currently available information and analysis – that remediation costs for all identified sites may exceed our accrual by up to $100 million.

19

That estimate – in which those additional costs may be incurred over several years – is the upper end of the range of reasonably possible additional costs. The estimate:

• is much less certain than the estimates on which our accruals currently are based and

• uses assumptions that are less favorable to us among the range of reasonably possible outcomes.

In estimating our current accruals and the possible range of additional future costs, we:

• assumed we will not bear the entire cost of remediation of every site,

• took into account the ability of other potentially responsible parties to participate and

• considered each party’s financial condition and probable contribution on a per-site basis.

We have not recorded any amounts for potential recoveries from insurance carriers.

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, 2011, our total accruals for these obligations was $59 million. The accruals have not changed materially since the end of 2010.

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

Regulation of Air Emissions in the U.S.

In March 2011, the United States Environmental Protection Agency (EPA) published a set of final rules that require use of maximum achievable control technology (MACT) for industrial boilers. As disclosed in our Annual Report on Form 10-K for the year ended December 31, 2010, we had previously estimated that we might spend as much as $30 million to $100 million over the next few years to comply with the MACT standards as they were described in the proposed rule. After reviewing the final rules, we now estimate that we might spend as much as $30 million to $45 million over the next few years to comply with the MACT standards. The EPA has stated that they intend to reconsider portions of the final rules in the coming months. Depending on the final outcome of the reconsideration process, our cost projection may change.

Regulation of Water in the U.S.

As a result of litigation (some of which is ongoing), additional federal or state permits may be required in the future under the federal Clean Water Act in one or more of the states in which we operate in relation to pollution discharges from forest roads and other drainage features on forest land and the application of pesticides, including herbicides, on forest lands. Such permits, which have not yet been developed, may entail additional costs. However, we do not expect a disproportionate effect on Weyerhaeuser as compared to comparable operations of other forest landowners.

NOTE 15:INCOME TAXES

As a REIT, we generally are not subject to corporate level tax on income of the REIT that is distributed to shareholders. We will, however, be 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 also will continue to be required to pay federal corporate income taxes on earnings of our Taxable REIT Subsidiary (TRS), which principally includes our manufacturing businesses, our real estate development business and the portion of our timberlands segment income included in the TRS.

The provision for income taxes is based on the current estimate of the annual effective tax rate. Our 2011 and 2010 income tax rates excluding discrete items are lower than the statutory rate, primarily due to the tax benefits of being a REIT.

20

Our effective income tax rates from continuing operations excluding discrete items were:

• (17.9) percent for 2011 and

• 16.8 percent for 2010.

Discrete items excluded from the calculation of our effective income tax rates include:

DOLLAR AMOUNTS IN MILLIONS
First Quarter 2011:
Income taxes on a non-strategic timberlands gain discussed in Note 8	$	(56	)
Second Quarter 2011:
Tax benefit on early extinguishment of debt discussed in Note 11	$	10
Third Quarter 2011:
Tax benefit related to foreign tax credits	$	83
First Quarter 2010:
Medicare Part D subsidy charge	$	(28	)
State tax law and rate changes charge	$	(3	)
Third Quarter 2010:
REIT conversion benefit	$	1,043
Medicare Part D subsidy plan change due to plan amendment	$	(4	)
Unrecognized tax benefits and other adjustments	$	(4	)

Due to the Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act, we no longer will be able to claim an income tax deduction for prescription drug benefits provided to retirees and reimbursed under the Medicare Part D subsidy beginning in 2013. During first quarter 2010, we recorded the effect of the change, as accounting rules require the effect of the change to be recorded in the period that the law was enacted.

During third quarter 2010, we reversed certain deferred income tax liabilities, relating to temporary differences of timber assets, as a result of our conversion to a REIT.

21

STATEMENTS

We make forward-looking statements of our expectations regarding fourth quarter 2011, including:

• reduced fee harvest volumes, lower selling prices for Western logs, seasonally higher road and silviculture expenses and lower earnings in our Timberlands segment excluding earnings from disposition of non-strategic timberlands;

• seasonally weaker market conditions, lower selling prices for lumber and oriented strand board, reduced sales volumes and operating rates across all products lines and a larger loss from continuing operations in our Wood Products segment excluding special items;

• lower selling prices for pulp, slightly higher shipment volumes and slightly lower earnings in our Cellulose Fibers segment; and

• higher earnings from single-family homebuilding operations and seasonally higher home closing volume in our Real Estate segment.

We base our forward-looking statements on a number of factors, including the expected effect of:

• the economy;

• performance of pension fund investments and related derivatives; and

• other factors described under “Risk Factors” in our annual report on Form 10-K.

EXPORTING ISSUES

We are a large exporter, affected by changes in:

• economic activity in Europe and Asia – particularly Japan and China;

• currency exchange rates – particularly the relative value of the U.S. dollar to the Canadian dollar, Euro and Yen; and

• restrictions on international trade or tariffs imposed on imports.

23

RESULTS OF OPERATIONS

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

• Price realizations refer to net selling prices – this includes selling price plus freight, minus normal sales deductions.

• Net contribution to earnings can be positive or negative and 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 the following:

• Net sales and revenues and operating income included in Consolidated Results below exclude the results of discontinued operations.

• Net sales and revenues and net contribution to earnings reported in the individual segment discussions that follow include the results of discontinued operations. Refer to Note 3: Discontinued Operations for a discussion of which segments include the results of our discontinued operations.

In the following discussion, unless otherwise noted, references to increases or decreases in income and expense items, price realizations, shipment volumes, and net contributions to earnings are based on the quarter and year-to-date periods ended September 30, 2011, compared to the quarter and year-to-date periods ended September 30, 2010.

Comparing Third Quarter 2011 with Third Quarter 2010

Net sales and revenues

Net sales and revenues increased $55 million – 4 percent – primarily due to the following:

• Wood Products segment sales increased $66 million, primarily due to higher price realizations and shipment volumes for structural lumber and higher shipment volumes for oriented stranded board (OSB); and

• Timberlands segment sales increased $12 million, primarily due to higher log prices and volumes sold, partially offset by lower revenue from land exchanges.

These increases were partially offset by a $19 million decrease in Cellulose Fibers segment sales, primarily due to lower pulp prices and volumes sold.

Net earnings attributable to Weyerhaeuser common shareholders

Our net earnings attributable to Weyerhaeuser common shareholders decreased $959 million – 86 percent – primarily due to the following:

• $1,043 million reversal of certain deferred income tax liabilities as a result of our conversion to a REIT in 2010;

• $35 million decrease in gross margin, primarily due to increased operating costs in our Cellulose Fibers segment and increased pension and postretirement costs in our Corporate and Other segment partially offset by increased operating rates in our Wood Products segment; and

• $25 million increase in restructuring, closure and asset impairment charges, primarily due to impairments recognized in our Wood Products segment.

These decreases in our earnings were partially offset by:

• $83 million tax benefit related to foreign tax credits in 2011;

• $26 million decrease in selling, general and administrative expenses; and

• $20 million increase in net earnings of discontinued operations, primarily due to the gain on the sale of Westwood Shipping Lines partially offset by the loss on the sale of our hardwoods operations.

Comparing Year-to-Date 2011 with Year-to-Date 2010

Net sales and revenues

Net sales and revenues increased $163 million – 4 percent – primarily due to the following:

• Cellulose Fibers segment sales increased $135 million, primarily due to higher pulp prices and

• Timberlands segment sales increased $103 million, primarily due to higher log prices and volumes sold.

These increases were partially offset by a $56 million decrease in Real Estate segment sales, primarily due to lower home closings and fewer land and lot sales.

25

Net earnings attributable to Weyerhaeuser common shareholders

Our net earnings attributable to Weyerhaeuser common shareholders decreased $844 million – 76 percent – primarily due to the following:

• $1,043 million reversal of certain deferred income tax liabilities as a result of our conversion to a REIT in 2010;

• $31 million decrease in gross margin, primarily due to decreased price realizations for OSB and structural lumber in our Wood Products segment, increased operating costs in our Cellulose Fibers segment and increased pension and postretirement costs in our Corporate and Other segment, partially offset by increased operating rates in our Wood Products segment;

• $30 million increase in restructuring, closure and asset impairment charges, primarily due to impairments recognized in our Wood Products segment;

• $23 million net gain on the sale of certain British Columbia forest licenses and associated rights recognized in our Wood Products segment in 2010; and

• $22 million net gain on the sale of partnership interests in our Real Estate segment in 2010.

These decreases were partially offset by the following:

• $96 million net gain on sale of 82,000 acres of non-strategic timberlands in 2011;

• $83 million tax benefit related to foreign tax credits in 2011;

• $60 million decrease in interest expense due to lower charges associated with the early extinguishment of debt and lower interest expense due to a lower level of debt;

• $28 million tax charge recognized in 2010 related to the federal tax law change for Medicare Part D subsidies; and

• $27 million decrease in selling, general and administrative expenses.

Comparing Third Quarter 2011 with Third Quarter 2010

Net sales and revenues – unaffiliated customers

Net sales and revenues to unaffiliated customers increased $12 million – 5 percent – primarily from the following:

• Western log sales increased by $34 million due to increased sales volumes of 15 percent and increased price realizations of 14 percent as a result of strong export demand.

• Southern log sales increased by $13 million due to increased sales volumes of 48 percent driven by increased harvest levels and increased sales of logs to third parties.

The above items were partially offset by a decrease of $39 million in land exchanges.

Intersegment sales

Intersegment sales increased $9 million – 6 percent – primarily due to increased Canadian log sales volumes.

27

Net contribution to earnings

Net contribution to earnings decreased $13 million – 17 percent – primarily from the following:

• $32 million decrease due to less land exchanges and higher and better-use land sales;

• $8 million decrease due to lower prices for logs in the South; and

• $7 million increase in operating costs, primarily due to higher fuel costs.

The above items were partially offset by:

• $19 million increase, primarily due to higher domestic and export prices in the West; and

• $16 million increase, primarily due to increased harvest levels of 11 percent in the West and 23 percent in the South.

Comparing Year-to-Date 2011 with Year-to-Date 2010

Net sales and revenues – unaffiliated customers

Net sales and revenues to unaffiliated customers increased $103 million – 15 percent – primarily from the following:

• Western log sales increased by $89 million due to increased sales volumes of 12 percent and increased price realizations of 14 percent driven by strong export demand.

• Southern log sales increased by $39 million due to increased sales volumes of 50 percent resulting from increased harvest levels and increased sales of logs to third parties.

• Sales from our International operations increased by $10 million, primarily due to increased plywood sales volumes of 27 percent.

The above items were partially offset by a decrease of $34 million in land exchanges and higher and better-use land sales.

Intersegment sales

Intersegment sales increased $40 million – 9 percent – primarily from the following:

• $27 million increase due to increased Canadian log and chip sales volumes and

• $13 million increase due to higher log prices in the West.

Net contribution to earnings

Net contribution to earnings increased $189 million – 84 percent – primarily from the following:

• $152 million pretax gain on the first quarter 2011 sale of 82,000 acres of non-strategic timberlands in southwestern Washington;

• $65 million increase, primarily due to higher domestic and export prices in the West; and

• $40 million increase, primarily due to increased harvest levels of 16 percent in both the West and the South.

The above items were partially offset by:

• $27 million increase in operating costs, primarily due to higher fuel and silviculture costs;

• $24 million decrease due to less land exchanges and higher and better-use land sales; and

• $13 million decrease due to lower prices for logs in the South.

28

Our Outlook

Excluding earnings from disposition of non-strategic timberlands, we expect lower earnings from the Timberlands segment in fourth quarter due to reduced fee harvest volumes and lower selling prices for Western logs. We also anticipate seasonally higher road and silviculture costs. We expect non-strategic timberlands sales to increase in fourth quarter from the very low third quarter level.

During third quarter 2011, we recognized $29 million of impairment charges in the Wood Products segment, primarily related to the decision to permanently close four engineered lumber facilities that had been previously indefinitely closed. These facilities are located in Albany, Oregon; Dodson, Louisiana; Pine Hill, Alabama; and Simsboro, Louisiana.

Comparing ThirdQuarter 2011 with Third Quarter 2010

Net sales and revenues, including discontinued operations

Net sales and revenues increased $4 million – primarily from the following:

• Structural lumber shipment volumes increased 5 percent and average price realizations increased 5 percent.

• Oriented strand board (OSB) shipment volumes increased 28 percent, primarily due to the re-opening of our Hudson Bay, Saskatchewan facility and increased production at our Grayling, Michigan facility to take advantage of regional market opportunities.

These increases were partially offset by decreased hardwood lumber sales due to the sale of our hardwoods operations.

Net contribution to earnings, including discontinued operations

Net contribution to earnings increased $7 million – 7 percent – primarily from the following:

• $24 million decrease in manufacturing costs, primarily due to increased operating rates;

• $16 million decrease in selling and administrative costs, primarily due to previous cost reduction efforts and the sale of our hardwoods operations; and

• $11 million increase, primarily due to higher sales price realizations for structural lumber.

30

These increases were partially offset by the following:

• $29 million increase in charges for restructuring, closure and asset impairments; and

• $13 million in charges related to the sale of our hardwoods operations.

Comparing Year-to-Date 2011 with Year-to-Date 2010

Net sales and revenues, including discontinued operations

Net sales and revenues decreased $63 million – 3 percent – primarily from the following:

• Structural lumber average price realizations decreased 4 percent.

• OSB average price realizations decreased 17 percent.

• Engineered solid section shipment volumes decreased 12 percent.

• Engineered I-joists shipment volumes decreased 16 percent.

• Hardwood lumber sales decreased due to the sale of our hardwoods operations.

• Other products purchased for resale decreased primarily as a result of ceasing to offer a composite decking product line and the sale of our hardwoods operations.

These decreases were partially offset by the following:

• Structural lumber shipment volumes increased 7 percent.

• OSB shipment volumes increased 24 percent, primarily due to the re-opening of our Hudson Bay, Saskatchewan facility and increased production at our Grayling, Michigan facility to take advantage of regional market opportunities.

• Engineered solid section average price realizations increased 5 percent.

• Engineered I-joists average price realizations increased 9 percent.

Net contribution to earnings, including discontinued operations

Net contribution to earnings decreased $68 million – 56 percent – primarily from the following:

• $67 million decrease due to lower sales price realizations, primarily for OSB and structural lumber;

• $40 million pretax gain on the sale of certain British Columbia forest licenses and associated rights in 2010;

• $33 million increase in charges for restructuring, closure and asset impairments;

• $22 million increase in charges related to the sale of our hardwoods operations; and

• $15 million increase in log costs as domestic prices increased in the West as a result of strong export demand.

These decreases were partially offset by the following:

• $58 million decrease in manufacturing costs, primarily due to increased operating rates and

• $47 million decrease in selling and administrative costs, primarily due to previous cost reduction efforts.

Our Outlook

Excluding special items, we anticipate a larger loss from continuing operations in fourth quarter due to seasonally weaker market conditions. We expect lower selling prices for lumber and OSB and reduced sales volumes and operating rates across all product lines.

32

Comparing Third Quarter 2011 with Third Quarter 2010

Net sales and revenues

Net sales and revenues decreased $19 million – 4 percent – primarily due to the following:

• Pulp price realizations decreased $7 per ton – 1 percent – primarily due to increasing global softwood pulp inventories;

• Sales volumes for pulp decreased 19,000 tons – 4 percent; and

• Sales volumes for liquid packaging board decreased 4,000 tons – 5 percent.

These increases were partially offset by an increase in liquid packaging board price realizations of $61 per ton –

6 percent – due to a favorable shift in product mix to coated board sales and an increase in market price.

Net contribution to earnings

Net contribution to earnings decreased $46 million – 25 percent – primarily due to the following:

• $20 million increase in prices for fiber and chemicals;

• $15 million increase in operating costs, maintenance, freight, energy and the effect on Canadian operating costs of the weakening U.S. dollar compared to the Canadian dollar; and

• $7 million decrease in pulp sales volume due to weaker demand.

Comparing Year-to-Date 2011 with Year-to-Date 2010

Net sales and revenues

Net sales and revenues increased $135 million – 10 percent – primarily due to the following:

• Pulp price realizations increased by $81 per ton – 9 percent – primarily due to lower global softwood pulp inventories in the first half of the year;

• Sales volumes for pulp increased 8,000 tons – 1 percent; and

• Liquid packaging board price realizations increased by $86 per ton – 8 percent – due to a favorable shift in product mix to coated board sales and an increase in market price.

Net contribution to earnings

Net contribution to earnings increased $27 million – 10 percent – primarily due to the following:

• $104 million increase due to higher pulp price realizations and

• $20 million improvement in liquid packaging board price realizations.

Partially offsetting these increases in earnings are the following:

• $53 million increase in operating costs, maintenance, freight, energy and the effect on Canadian operating costs of the weakening U.S. dollar compared to the Canadian dollar; and

• $43 million increase, primarily due to rising fiber and chemical costs.

Our Outlook

We expect slightly lower earnings from the Cellulose Fibers segment in fourth quarter. We anticipate lower selling prices for pulp and slightly higher shipment volumes.

Markets for new homes are highly differential across our operations with uneven demand patterns. Buyers have been attracted by housing affordability and historically low mortgage rates, but strict mortgage qualification requirements and appraisal issues remain a challenge. In addition, tax credits available to many buyers in the first half of 2010 are no longer available in 2011. Although the supply of new homes is at record lows, most of our markets have been affected by high levels of foreclosures, high unemployment and low consumer confidence. We experienced a decrease in traffic in both third quarter and year-to-date 2011 compared to the same periods in 2010; however, our traffic conversion rate improved 44 percent in third quarter and 39 percent year-to-date.

Comparing Third Quarter 2011 with Third Quarter 2010

Net sales and revenues

Net sales and revenues were relatively flat as the following changes offset one another:

• Revenues from single family housing increased $4 million, as a result of slight increases in closing volume and the average price of homes closed.

• Revenues from land and lot sales decreased $4 million. Land and lot sales are a routine part of our land development business, but they do not occur evenly throughout the year.

Net contribution to earnings

Net contribution to earnings decreased $10 million – 50 percent – primarily from:

• $6 million decrease in contribution from partnership interests due to limited activity in third quarter 2011.

• $3 million decrease in contribution from non-single-family operations, as there were no significant land sales in third quarter 2011.

• $2 million decrease in contribution from single-family operations. Unit closings increased slightly, but margins declined due to a shift in the mix of homes closed. Changes in mix reflect both changes in product lines (entry-level homes versus move-up products) and changes in geographic markets where the closings occur.

These decreases were partially offset by a $4 million decrease in selling, general and administrative expenses.

35

Comparing Year-to-Date 2011 with Year-to-Date 2010

Net sales and revenues

Net sales and revenues decreased $56 million – 9 percent – primarily from:

• Home closings declined 12 percent to 1,330 in 2011 from 1,519 in 2010.

• Revenues from land and lot sales decreased $16 million.

These decreases in net sales and revenues were partially offset by a 6 percent increase in the average price of single-family homes closed to $403,000 in 2011 from $379,000 in 2010, primarily due to a shift in mix.

Net contribution to earnings

Net contribution to earnings decreased $61 million – 78 percent – primarily from:

• $33 million decrease in contribution from the sale of partnership interests – first quarter 2010 included the sale of interests in two commercial partnerships;

• $17 million decrease in contribution from single-family operations due to fewer home closings;

• $15 million decrease in contribution from land and lot sales; and

• $11 million decrease in contribution from partnerships interests.

These decreases were partially offset by the following improvements:

• $8 million decrease in selling, general and administrative expenses, resulting from both lower closing volumes and ongoing cost reduction efforts; and

• $5 million increase in single-family operations, primarily related to a change in mix resulting in a higher average price of homes closed.

Our Outlook

We anticipate higher earnings from single-family homebuilding operations in fourth quarter due to seasonally higher home closing volume. While none of significance are under contract at this time, we do have some land parcels that have the potential to close in fourth quarter.

CORPORATE AND OTHER

Corporate and Other includes certain gains or charges that are not related to an individual operating segment and the portion of items such as share-based compensation, pension and postretirement costs, foreign exchange transaction gains and losses associated with financing and other general and administrative expenses that are not allocated to the business segments. Historically, Corporate and Other included the results of our transportation operations. This included our five short line railroads that were sold at the end of 2010 and Westwood Shipping Lines that was sold on September 30, 2011. Westwood results are included in our results of discontinued operations.

How We Did Third Quarter and Year-to-Date 2011

Here is a comparison of net sales and revenues and net contribution to earnings for the quarters and year-to-date periods ended September 30, 2011 and 2010:

NET SALES AND REVENUES / NET CONTRIBUTIONS TO EARNINGS – CORPORATE AND OTHER

	QUARTER ENDED						AMOUNT OF CHANGE			YEAR-TO-DATE ENDED						AMOUNT OF CHANGE
DOLLAR AMOUNTS IN MILLIONS	SEPTEMBER 2011			SEPTEMBER 2010			2011 VS. 2010			SEPTEMBER 2011			SEPTEMBER 2010			2011 VS. 2010

Comparing Third Quarter 2011 with Third Quarter 2010

Net sales and revenues, including discontinued operations

Net sales and revenues decreased $10 million – 15 percent. Westwood revenues decreased as a result of lower volumes and prices. Thirdquarter 2011 does not include revenues of five short line railroads that we sold at the end of 2010.

Net contribution to earnings, including discontinued operations

Net contribution to earnings increased $28 million, primarily due to the following:

• $49 million gain on the sale of Westwood Shipping Lines; and

• $20 million increase due to a 29 percent decrease in our stock price in third quarter 2011, which resulted in lower share-based compensation expense.

Partially offsetting these increases in earnings is the following:

• $24 million increase in pension and postretirement costs, primarily due to the amortization of deferred pension losses; and

• $21 million change in foreign exchange, primarily as a result of a weaker Canadian dollar relative to the U.S. dollar in 2011.

Comparing Year-to-Date 2011 with Year-to-Date 2010

Net sales and revenues, including discontinued operations

Net sales and revenues decreased $4 million – 2 percent. Year-to-date 2011 does not include revenues of five short line railroads that we sold at the end of 2010. This was partially offset by an increase in Westwood revenues as a result of higher volumes.

37

Net contribution to earnings, including discontinued operations

Net contribution to earnings decreased $55 million, primarily due to the following:

• $77 million increase in pension and postretirement costs, primarily due to the amortization of deferred pension losses;

• $15 million change in foreign exchange, primarily as a result of a weaker Canadian dollar relative to the U.S. dollar in 2011; and

• $11 increase in environmental remediation expense related to discontinued operations.

These decreases were partially offset by the $49 million gain on the sale of Westwood Shipping Lines.

INTEREST EXPENSE

Our net interest expense incurred was:

• $86 million during third quarter and $296 million during year-to-date2011.

• $95 million during third quarter and $356 million during year-to-date2010.

Interest expense incurred decreased in the quarter, primarily due to a lower level of debt. Year-to-date interest expense incurred decreased, primarily due to lower charges associated with the early extinguishment of debt and a lower level of debt.

At the beginning of June 2011, we exercised our right to call approximately $518 million of 6.75 percent notes due in 2012. We recognized a pretax charge in second quarter 2011 of $26 million, which included early retirement premiums, unamortized debt issuance costs and other miscellaneous charges in connection with the early extinguishment of debt. This charge is included in our net interest expense.

Year-to-date 2010 net interest expense includes a pretax charge of $49 million, which included early retirement premiums, unamortized debt issuance costs and other miscellaneous charges in connection with the early extinguishment of debt.

INCOME TAXES

As a REIT, we generally are not subject to corporate level tax on income of the REIT that is distributed to shareholders. We will, however, be 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 also will continue to be required to pay federal corporate income taxes on earnings of our Taxable REIT Subsidiary (TRS), which principally includes our manufacturing businesses, our real estate development business and the portion of our timberlands segment income included in the TRS.

The provision for income taxes is based on the current estimate of the annual effective tax rate. Our 2011 and 2010 income tax rates excluding discrete items are lower than the statutory rate, primarily due to the tax benefits of being a REIT.

Our effective income tax rates from continuing operations excluding discrete items were:

• (17.9) percent for 2011 and

• 16.8 percent for 2010.

38

Discrete items excluded from the calculation of our effective income tax rates include:

DOLLAR AMOUNTS IN MILLIONS
First Quarter 2011:
Income taxes on a non-strategic timberlands gain	$	(56	)
Second Quarter 2011:
Tax benefit on early extinguishment of debt	$	10
Third Quarter 2011:
Tax benefit related to foreign tax credits	$	83
First Quarter 2010:
Medicare Part D subsidy charge	$	(28	)
State tax law and rate changes charge	$	(3	)
Third Quarter 2010:
REIT conversion benefit	$	1,043
Medicare Part D subsidy plan change due to plan amendment	$	(4	)
Unrecognized tax benefits and other adjustments	$	(4	)

Due to the Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act, we no longer will be able to claim an income tax deduction for prescription drug benefits provided to retirees and reimbursed under the Medicare Part D subsidy beginning in 2013. During first quarter 2010, we recorded the effect of the change, as accounting rules require the effect of the change to be recorded in the period that the law was enacted.

During third quarter 2010, we reversed certain deferred income tax liabilities, relating to temporary differences of timber assets, as a result of our conversion to a REIT.

LIQUIDITY AND CAPITAL RESOURCES

We are committed to maintaining a sound and conservative capital structure which enables us to:

• protect the interests of our shareholders and lenders and

• have access at all times to all major financial markets.

Two important elements of our policy governing capital structure include:

• viewing the capital structure of Forest Products separately from that of Real Estate given the very different nature of their assets and business activity and

• minimizing liquidity risk by managing a combination of maturing short-term and long-term debt.

The amount of debt and equity for Forest Products and Real Estate will reflect the following:

• basic earnings capacity and

• liquidity characteristics of their respective assets.

CASH FROM OPERATIONS

Cash from operations includes:

• cash received from customers;

• cash paid to employees, suppliers and others;

• cash paid for interest on our debt; and

• cash paid for taxes.

39

Consolidated net cash provided by our operations was:

• $144 million in 2011 and

• $464 million in 2010.

Comparing 2011 with 2010

Net cash from operations decreased $320 million in 2011 as compared with 2010, primarily due to the following:

• Net cash inflows related to income taxes decreased $465 million. We paid taxes of $21 million in 2011 and received income tax refunds of $444 million in 2010.

• Cash paid to employees, suppliers and others increased approximately $45 million.

Partially offsetting the above decreases was an increase in cash we received from customers of approximately $184 million, primarily due to increased net sales and revenues from our Cellulose Fibers and Timberlands segments partially offset by decreased net sales in our Wood Products and Real Estate segments.

During fourth quarter 2011, our Real Estate segment expects to pay approximately $30 million in settlement of litigation in which we are a minority party. This amount is covered by a reserve that was recorded in 2008.

CASH FROM INVESTING ACTIVITIES

Cash from investing activities can include:

• acquisitions of property, equipment, timberlands and reforestation;

• investments in or distribution from equity affiliates;

• proceeds from sale of assets and operations; and

• purchases and redemptions of short-term investments.

In year-to-date2010, the pension trust repaid $146 million of short-term loans made in 2008 and 2009.

Summary of Capital Spending by Business Segment

	YEAR-TO-DATE ENDED
DOLLAR AMOUNTS IN MILLIONS	SEPTEMBER 2011		SEPTEMBER 2010
Timberlands	$	40	$	52
Wood Products	23		12
Cellulose Fibers(1)	92		77
Corporate and Other	2		1
Real Estate	2		3
Total	$	159	$	145

(1) 2010 includes the exercise of an option to acquire liquid packaging board extrusion equipment for $21 million, including assumption of liabilities of $4 million.

We anticipate that our net capital expenditures for 2011 – excluding acquisitions – will be approximately

$250 million to $270 million.

40

Proceeds from the Sale of Nonstrategic Assets

Proceeds received from the sale of nonstrategic assets were $353 million in 2011. This included:

• $192 million for the sale of 82,000 acres of non-strategic timberlands in southwestern Washington;

• $84 million for the sale of our hardwoods operations (we expect to receive an additional $25 million in 2016 from a note receivable);

• $58 million for the sale of our Westwood Shipping Lines operations; and

• $19 million for the sale of other non-strategic assets.

Proceeds received from the sale of nonstrategic assets were $160 million in 2010. This included:

• $66 million for the sale of Wood Products assets,

• $40 million for the sale of British Columbia forest licenses and associated rights,

• $33 million for the sale of partnership interests in our Real Estate segment and

• $21 million for the sale of other non-strategic assets.

CASH FROM FINANCING ACTIVITIES

Cash from financing activities can include:

• issuances and payment of long-term debt,

• borrowings and payments under revolving lines of credit,

• changes in our book overdrafts,

• proceeds from stock offerings and option exercises and

• payment of cash dividends and repurchasing stock.

Debt

We repaid debt of:

• $550 million in 2011 and

• $570 million in 2010.

At the beginning of June 2011, we exercised our right to call approximately $518 million of 6.75 percent notes due in 2012.

Real Estate debt maturities were $32 million during 2011. Subsequent to quarter end, we retired an additional $13 million of 6.12 percent Real Estate notes with a maturity date of September 17, 2012.

Long-term debt and revolving credit facility

During June 2011, Weyerhaeuser Company and Weyerhaeuser Real Estate Company (WRECO) entered into a new $1.0 billion 4-year revolving credit facility that expires in June 2015. This replaces a $1.0 billion revolving credit facility that was set to expire December 2011. WRECO can borrow up to $50 million under this facility. Neither of the entities is a guarantor of the borrowing of the other under this credit facility.

There were no net proceeds from the issuance of debt or from borrowings (repayments) under our available credit facility in year-to-date2011 or 2010.

41

Debt covenants

As of September 30, 2011 Weyerhaeuser Company and WRECO:

• had no borrowings outstanding under the credit facility and

• were in compliance with the credit facility covenants.

Weyerhaeuser Company Covenants

• a minimum defined net worth of $3.0 billion;

• a defined debt-to-total-capital ratio of 65 percent or less; and

• minus Weyerhaeuser Company’s investment in subsidiaries in our Real Estate segment or other unrestricted subsidiaries.

Total Weyerhaeuser Company capitalization is comprised of:

• total Weyerhaeuser Company (excluding WRECO) debt

As of September 30, 2011, Weyerhaeuser Company had:

• a defined net worth of $5 billion and

• a defined debt-to-total-capital ratio of 46.0 percent.

Weyerhaeuser Real Estate Company Covenants

Option Exercises

We received cash proceeds of $37 million from the exercise of stock options in year-to-date2011.

Paying dividends and repurchasing stock

We paid dividends of:

• $242 million in 2011 and

• $581 million in 2010.

The decrease in dividends paid is primarily due to the Special Dividend paid on September 1, 2010. This decrease is partially offset by the increase in our quarterly dividend from 5 cents to 15 cents in February 2011 and the increase in the number of our common shares outstanding as a result of the Special Dividend.

On October 13, 2011, our board of directors declared a regular dividend of 15 cents per share payable December 1, 2011, to shareholders of record at the close of business November 11, 2011.

During third quarter 2011, we repurchased 1,199,800 shares of common stock for $20 million under the 2008 stock repurchase program. On August 11, 2011, our board of directors replaced the 2008 stock repurchase program and approved the 2011 stock repurchase program under which we are authorized to repurchase up to $250 million of outstanding shares. During third quarter 2011, we repurchased 589,824 shares of common stock for $9 million under the 2011 program. Cash settlements of $5 million occurred at the beginning of the fourth quarter. All common stock purchases under the programs were made in open-market transactions. As of September 30, 2011, we had remaining authorization of $241 million for future share repurchases.

CRITICAL ACCOUNTING POLICIES

There have been no significant changes during year-to-date2011 to our critical accounting policies presented in our 2010 Annual Report on Form 10-K.

43

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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, 2011, based on an evaluation of the company’s disclosure controls and procedures as of that date.

CHANGES IN INTERNAL CONTROLS

No changes occurred in the company’s internal control over financial reporting during year-to-date 2011 that have materially affected, or are reasonably likely to materially affect, the company’s internal control over financial reporting.

LEGAL PROCEEDINGS

Refer to “Notes to Consolidated Financial Statements – Note 14: Legal Proceedings, Commitments and Contingencies.”

RISK FACTORS

Southern Yellow Pine Design Values

The Southern Pine Inspection Bureau (SPIB) has submitted proposed design value changes to the American Lumber Standards Committee (ALSC) for all grades and sizes of visually graded southern yellow pine lumber. The proposed changes were the result of tests on southern yellow pine 2x4 specimens that showed reductions in certain design values. Our Southern timberlands predominantly contain southern yellow pine. We sell both visually graded and mechanically graded southern yellow pine. Under the SPIB proposal, design values for mechanically graded lumber would not change. The test data has now been released for review and the ALSC has set a public hearing in January to discuss the test procedures and results. At this time, it is unknown what decision will be made by the ALSC Board of Review, the basis for the changes or the timing for their implementation. If design value reductions are implemented by ALSC for visually graded southern yellow pine, the change could result in an increase in product substitution or species substitution and could adversely affect demand for visually graded southern yellow pine.

See our 2010 Annual Report on Form 10-K for other risk factors that affect our business.

Earnings Per Share, Basic and Diluted [Abstract]

Earnings Per Share, Policy

Basic earnings per share is net earnings divided by the weighted average number of our outstanding common shares.

Diluted earnings per share is net earnings divided by the sum of the:

• weighted average number of our outstanding common shares and

• the effect of our outstanding dilutive potential common shares.

Dilutive potential common shares can include:

• outstanding stock options,

• restricted stock units and

• performance share units.

We use the treasury stock method to calculate the effect of our outstanding dilutive potential common shares. 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.

Pension and Other Postretirement Plans, Pensions, Policy

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. When the differences are significant, we revise the year-end estimated fair value of pension plan assets to incorporate year-end net asset values reflected in audited financial statements received after we have filed our annual report on Form 10-K.

SHARE-BASED COMPENSATION

SHARE-BASED COMPENSATION

In 2011, we granted 1,941,686 stock options, 720,120 restricted stock units, 325,736 performance share units, and 52,869 stock appreciation rights. In addition, 283,557 outstanding restricted stock unit awards vested during year-to-date2011. A total of 2,710,962 shares of common stock were issued as a result of restricted stock unit vesting and stock option exercises.

STOCK OPTIONS

The weighted average exercise price of all of the stock options granted in 2011 was $24.16. The vesting and post-termination vesting terms for stock options granted in 2011 were as follows:

• options vest ratably over 4 years;

• options vest or continue to vest in the event of death, disability, or retirement at an age of at least 62;

• options continue vesting for one year in the event of involuntary termination when the retirement criteria for full or continued vesting have not been met; and

• options stop vesting for all other situations including early retirement prior to age 62.

Expected volatility	38.56		%
Expected dividends	2.48		%
Expected term (in years)	5.73
Risk-free rate	2.65		%
Weighted average grant date fair value	$	7.54

RESTRICTED STOCK UNITS

The weighted average fair value of the restricted stock units granted 2011 was $23.94. The vesting provisions for restricted stock units granted in 2011 were as follows:

• restricted stock units vest ratably over 4 years;

• restricted stock units immediately vest in the event of death while employed or disability;

• restricted stock units partially vest upon retirement at an age of at least 62 or job elimination depending on the employment period after grant date; and

• restricted stock units will be forfeited upon termination of employment in all other situations including early retirement prior to age 62.

PERFORMANCE SHARE UNITS

In 2011, as part of a new long-term incentive compensation strategy intended to tie executive compensation more closely to company performance, we granted a target number of performance share units to executives. Performance share units will be converted into shares of Weyerhaeuser stock – to the extent earned – at the end of a four-year timeframe that combines performance and market conditions with vesting requirements. The final number of shares awarded will range from 0 percent to 150 percent of each grant’s target, depending upon actual company performance.

The ultimate number of Performance Share Units earned is based on two measures:

• Weyerhaeuser’s cash flow during the first year and

• Weyerhaeuser’s relative total shareholder return (TSR) ranking in the S&P 500 during the first two years.

At the end of the performance period, performance share unit payouts would be in shares of our stock. Performance share units granted in 2011 and that are earned vest as follows:

• units vest 50 percent, 25 percent and 25 percent on the second, third and fourth anniversaries of the grant date, respectively, as long as the individual remains employed by the company;

• units fully vest in the event of death while employed or disability;

• units partially vest upon retirement at an age of at least 62 or job elimination depending on the employment period after grant date; and

• units will be forfeited upon termination of employment in all other situations including early retirement prior to age 62.

The weighted average grant date fair value of the performance share units was $25.35. Since the award contains a market condition, the effect of the market condition is reflected in the grant date fair value which is estimated using a Monte Carlo simulation model. This model estimates the TSR ranking of the company among the S&P 500 index over the 2 year performance period. Compensation expense is based on the estimated probable number of earned awards and recognized over the four-year vesting period on an accelerated basis. Generally, compensation expense would be reversed if the performance condition is not met unless the requisite service period has been achieved.

Commitments and Contingencies Disclosure [Abstract]

Environmental Costs, Policy

We change our accrual to reflect:

• new information on any site concerning implementation of remediation alternatives,

• updates on prior cost estimates and new sites and

• costs incurred to remediate sites.

We believe it is reasonably possible – based on currently available information and analysis – that remediation costs for all identified sites may exceed our accrual by up to $100 million.

That estimate – in which those additional costs may be incurred over several years – is the upper end of the range of reasonably possible additional costs. The estimate:

• is much less certain than the estimates on which our accruals currently are based and

• uses assumptions that are less favorable to us among the range of reasonably possible outcomes.

In estimating our current accruals and the possible range of additional future costs, we:

• assumed we will not bear the entire cost of remediation of every site,

• took into account the ability of other potentially responsible parties to participate and

• considered each party’s financial condition and probable contribution on a per-site basis.

FAIR VALUE OF FINANCIAL INSTRUMENTS [Abstract]

Fair Value of Financial Instruments, Policy

To estimate the fair value of long-term debt, we used the following valuation approaches:

• market approach – based on quoted market prices 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.

The inputs to the 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.

To estimate the fair value of long-term debt, we used the following valuation approaches:

• market approach – based on quoted market prices 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.

The inputs to the 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.

At the beginning of June 2011, we exercised our right to call approximately $518 million of 6.75 percent notes due in 2012. We recognized a pretax charge in 2011 of $26 million, which included early retirement premiums, unamortized debt issuance costs and other miscellaneous charges in connection with the early extinguishment of debt. This charge is included in interest expense in the Consolidated Statement of Operations.

Real Estate debt maturities were $32 million during 2011.

FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS

We believe that our other financial instruments, including cash, short-term investments, 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.

Disclosures about Employer's Participation in a Multiemployer Pension Plan

Accounting Standards Update (“ASU”) No. 2011-09 dealing with multiemployer pension plans was issued by the FASB in September 2011. The ASU takes effect in fourth quarter 2011 and requires quantitative and qualitative disclosure about:

• significant multiemployer plans in which an employer participates, including plan names and identifying number;

• level of an employer's participation in the plans, including the employer's contributions made to the plans and an indication of whether the employer's contributions represent more than five percent of the total contributions made to the plan by all contributing employers;

• financial health of the significant multiemployer plans, including an indication of the funded status, whether funding improvement plans are pending or implemented and whether the plan has imposed surcharges on the contributions to the plan; and

• nature of the employer commitments to the plan, including when the collective-bargaining agreements that require contributions to the plans are set to expire and whether those agreements require minimum contributions to be made to the plans.

We are currently evaluating the effect that the adoption of ASU No. 2011-09 will have on our disclosures.

The $152 million pretax gain on sale of non-strategic timberlands resulted from the sale of 82,000 acres in southwestern Washington.

Gain on disposal of assets in 2010 included pretax gains of $40 million from the sale of certain British Columbia forest licenses and associated rights.

Foreign exchange losses (gains) result from changes in exchange rates, primarily related to our Canadian operations.

Land management income consists primarily of income derived from leasing, renting and granting easement and rights of way on our timberlands.

SALE OF HARDWOODS

On August 1, 2011, we completed the sale of our hardwoods operations to American Industrial Partners for consideration of $109 million, of which $25 million is a note receivable. During second quarter 2011, we reduced our hardwoods assets to their fair value less selling costs which resulted in the recognition of a $9 million charge. An additional $10 million pension curtailment charge was recognized in third quarter 2011 when the transaction closed. Total pre-tax charges on the sale of $22 million were recorded in our Wood Products segment. We recognized a tax benefit on the sale of $8 million resulting in a year-to-date net loss of $14 million.

The following operating assets were included as part of the transaction:

• seven primary hardwood mills with a total capacity of 300 million board feet,

• four concentration yards,

• three remanufacturing plants,

• one log merchandising yard and

• sales offices in the U.S., Canada, Japan, China and Hong Kong.

SALE OF WESTWOOD SHIPPING LINES

On September 30, 2011, we completed the sale of Westwood Shipping Lines to J-WesCo of Japan for $58 million in cash. We recognized a pre-tax gain of $49 million in Corporate and Other and recorded tax expense of $18 million, resulting in a net gain of $31 million. This transaction also reduced our operating lease obligations as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2010 by approximately $130 million.

BUSINESS SEGMENTS

BUSINESS SEGMENTS

We are principally engaged in the growing and harvesting of timber; the manufacture, distribution and sale of forest products; and real estate development and construction. Our principal business segments are:

• Timberlands – which includes logs; timber; minerals, oil and gas; and international wood products;

• Wood Products – which includes softwood lumber, engineered lumber, structural panels and building materials distribution;

• Cellulose Fibers – which includes pulp, liquid packaging board and an equity interest in a newsprint joint venture; and

• Real Estate – which includes real estate development, construction and sales.

We sold our hardwoods operations in a transaction that closed on August 1, 2011. The hardwoods results are included in our Wood Products segment and results of discontinued operations for all periods presented in this report.

Corporate and Other includes certain gains or charges that are not related to an individual operating segment and the portion of items such as share-based compensation, pension and postretirement costs, foreign exchange transaction gains and losses associated with financing and other general and administrative expenses that are not allocated to the business segments. Historically, Corporate and Other included the results of our transportation operations. This included our five short line railroads that were sold at the end of 2010 and Westwood Shipping Lines that was sold on September 30, 2011. Westwood results are included in our results of discontinued operations.

Loss due to curtailment and special termination benefits includes charges of $11 million related to the sale of our hardwoods and Westwood Shipping Lines operations in third quarter 2011. These charges are included in our results of discontinued operations.

FAIR VALUE OF PENSION PLAN ASSETS

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. When the differences are significant, we revise the year-end estimated fair value of pension plan assets to incorporate year-end net asset values reflected in audited financial statements received after we have filed our annual report on Form 10-K. Based on the final valuations as of December 31, 2010, the fair value of pension assets increased in second quarter 2011 by $138 million, or 2.9 percent. Based on this information we recorded the following adjustments during second quarter 2011:

• $20 million increase in the pension asset;

• $86 million decrease in the liability for deferred pension;

• $38 million increase in the liability for deferred income taxes; and

• $68 million net decrease in cumulative other comprehensive loss, which resulted in an increase in total Weyerhaeuser shareholders' interest.

EXPECTED CONTRIBUTIONS AND BENEFIT PAYMENTS

During 2011 we expect to:

• be required to contribute approximately $83 million to our Canadian registered and nonregistered pension plans;

• contribute $19 million to our U.S. nonqualified pension plans and have no required contribution to the U.S. qualified plan; and

• make benefit payments of $44 million to our U.S. and Canadian other postretirement plans.

NET EARNINGS PER SHARE

NET EARNINGS PER SHARE

Our basic earnings per share attributable to Weyerhaeuser shareholders were:

• $0.29 during third quarter and $0.49 during year-to-date2011; and

• $3.52 during third quarter and $4.49 during year-to-date2010.

Our diluted earnings per share attributable to Weyerhaeuser shareholders were:

• $0.29 during third quarter and $0.49 during year-to-date2011; and

• $3.50 during third quarter and $4.48 during year-to-date2010.

Basic earnings per share is net earnings divided by the weighted average number of our outstanding common shares.

Diluted earnings per share is net earnings divided by the sum of the:

• weighted average number of our outstanding common shares and

• the effect of our outstanding dilutive potential common shares.

Dilutive potential common shares can include:

• outstanding stock options,

• restricted stock units and

• performance share units.

We use the treasury stock method to calculate the effect of our outstanding dilutive potential common shares. 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.

To implement our decision to be taxed as a REIT, we distributed our accumulated earnings and profits to our shareholders, determined under federal income tax provisions, as a “Special Dividend.” At the election of each shareholder, the Special Dividend was paid in cash or Weyerhaeuser common shares. The Special Dividend of $5.6 billion was paid September 1, 2010 and included approximately 324 million common shares. The stock portion of the Special Dividend was treated as the issuance of new shares for accounting purposes and affects our earnings per share only for periods after the distribution. Prior periods are not restated. The required treatment results in earnings per share that is less than would have been the case had the common shares not been issued. Reflected below are pro forma results giving effect to the common stock distribution for diluted earnings per common share for the quarter and year-to-date period ended September 30, 2010 as if the common stock distribution had occurred at the beginning of the period.

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.

During third quarter 2011, we repurchased 1,199,800 shares of common stock for $20 million under the 2008 stock repurchase program. On August 11, 2011, our board of directors replaced the 2008 stock repurchase program and approved the 2011 stock repurchase program under which we are authorized to repurchase up to $250 million of outstanding shares. During third quarter 2011, we repurchased 589,824 shares of common stock for $9 million under the 2011 program. All common stock purchases under the programs were made in open-market transactions. As of September 30, 2011, we had remaining authorization of $241 million for future share repurchases.

INCOME TAXES

INCOME TAXES

As a REIT, we generally are not subject to corporate level tax on income of the REIT that is distributed to shareholders. We will, however, be 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 also will continue to be required to pay federal corporate income taxes on earnings of our Taxable REIT Subsidiary (TRS), which principally includes our manufacturing businesses, our real estate development business and the portion of our timberlands segment income included in the TRS.

The provision for income taxes is based on the current estimate of the annual effective tax rate. Our 2011 and 2010 income tax rates excluding discrete items are lower than the statutory rate, primarily due to the tax benefits of being a REIT.

Our effective income tax rates from continuing operations excluding discrete items were:

• (17.9) percent for 2011 and

• 16.8 percent for 2010.

Discrete items excluded from the calculation of our effective income tax rates include:

DOLLAR AMOUNTS IN MILLIONS
First Quarter 2011:
Income taxes on a non-strategic timberlands gain discussed in Note 8	$	(56	)
Second Quarter 2011:
Tax benefit on early extinguishment of debt discussed in Note 11	$	10
Third Quarter 2011:

Third Quarter 2010:
REIT conversion benefit	$	1,043
Medicare Part D subsidy plan change due to plan amendment	$	(4	)
Unrecognized tax benefits and other adjustments	$	(4	)

Due to the Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act, we no longer will be able to claim an income tax deduction for prescription drug benefits provided to retirees and reimbursed under the Medicare Part D subsidy beginning in 2013. During first quarter 2010, we recorded the effect of the change, as accounting rules require the effect of the change to be recorded in the period that the law was enacted.

During third quarter 2010, we reversed certain deferred income tax liabilities, relating to temporary differences of timber assets, as a result of our conversion to a REIT.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

BASIS OF PRESENTATION

BASIS OF PRESENTATION

We are a corporation that has elected to be taxed as a real estate investment trust (REIT). As a REIT, we expect to derive most of our REIT income from investments in timberlands, including the sale of standing timber through pay-as-cut sales contracts. REIT income can be 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. 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 also will continue to be required to pay federal corporate income taxes on earnings of our Taxable REIT Subsidiary (TRS), which principally includes our manufacturing businesses, our real estate development business and our non-qualified timberland segment income.

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

• 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 as a separate component of equity.

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.

We report our financial condition in two groups:

• Forest Products – our forest products-based operations, principally the growing and harvesting of timber, the manufacture, distribution and sale of forest products and corporate governance activities; and

• Real Estate – our real estate development and construction operations.

Throughout these Notes to Consolidated Financial Statements, unless specified otherwise, references to “Weyerhaeuser,” “we” and “our” refer to the consolidated company, including both Forest Products and Real Estate.

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, 2010.

RECLASSIFICATIONS

We have reclassified certain balances and results from the prior year to be consistent with our 2011 reporting. This makes year-to-year comparisons easier. Our reclassifications had no effect on net earnings or Weyerhaeuser shareholders’ interest. The reclassifications include changes to the way we classify certain transactions as operating, investing or financing on our Consolidated Statement of Cash Flows and to present the results of operations discontinued in 2011 separately on our Consolidated Statement of Operations. Note 3: Discontinued Operations provides information about our discontinued operations.

LEGAL PROCEEDINGS, COMMITMENTS AND CONTINGENCIES

LEGAL PROCEEDINGS, COMMITMENTS AND CONTINGENCIES

This note provides details about our:

• legal proceedings and

• environmental matters.

LEGAL PROCEEDINGS

We are party to legal matters generally incidental to our business. The ultimate outcome of any legal proceeding:

• is subject to a great many variables and

• cannot be predicted with any degree of certainty.

However, whenever probable losses from litigation could reasonably be determined – we believe that we have established adequate reserves. In addition, we believe the ultimate outcome of the legal proceedings:

• could have a material adverse effect on our results of operations, cash flows or financial position in any given quarter or year; but

• will not have a material adverse effect on our long-term results of operations, cash flows or financial position.

Current Year Claim

On April 25, 2011, a complaint was filed in the United States District Court for the Western District of Washington on behalf of a person alleged to be a participant in the company’s U.S. Retirement Plan for salaried employees. The complaint alleges violations of the Employee Retirement Security Act (ERISA) with respect to the management of the plan’s assets and seeks certification as a class action. The company believes that its pension plans have been consistently managed in full compliance with established fiduciary standards and is vigorously contesting the claim. The company has filed a motion to dismiss the claim.

ENVIRONMENTAL MATTERS

Our environmental matters include:

• site remediation,

• asset retirement obligations,

• regulation of air emissions in the U.S. and

• regulation of water in the U.S.

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.

As of September 30, 2011, our total accrual for future estimated remediation costs on the active Superfund sites and other sites for which we are responsible was $36 million. This includes an $11 million increase to the reserve that was accrued in second quarter 2011 and is included in our results from discontinued operations.

We change our accrual to reflect:

• new information on any site concerning implementation of remediation alternatives,

• updates on prior cost estimates and new sites and

• costs incurred to remediate sites.

We believe it is reasonably possible – based on currently available information and analysis – that remediation costs for all identified sites may exceed our accrual by up to $100 million.

That estimate – in which those additional costs may be incurred over several years – is the upper end of the range of reasonably possible additional costs. The estimate:

• is much less certain than the estimates on which our accruals currently are based and

• uses assumptions that are less favorable to us among the range of reasonably possible outcomes.

In estimating our current accruals and the possible range of additional future costs, we:

• assumed we will not bear the entire cost of remediation of every site,

• took into account the ability of other potentially responsible parties to participate and

• considered each party’s financial condition and probable contribution on a per-site basis.

We have not recorded any amounts for potential recoveries from insurance carriers.

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, 2011, our total accruals for these obligations was $59 million. The accruals have not changed materially since the end of 2010.

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

Regulation of Air Emissions in the U.S.

In March 2011, the United States Environmental Protection Agency (EPA) published a set of final rules that require use of maximum achievable control technology (MACT) for industrial boilers. As disclosed in our Annual Report on Form 10-K for the year ended December 31, 2010, we had previously estimated that we might spend as much as $30 million to $100 million over the next few years to comply with the MACT standards as they were described in the proposed rule. After reviewing the final rules, we now estimate that we might spend as much as $30 million to $45 million over the next few years to comply with the MACT standards. The EPA has stated that they intend to reconsider portions of the final rules in the coming months. Depending on the final outcome of the reconsideration process, our cost projection may change.

Regulation of Water in the U.S.

As a result of litigation (some of which is ongoing), additional federal or state permits may be required in the future under the federal Clean Water Act in one or more of the states in which we operate in relation to pollution discharges from forest roads and other drainage features on forest land and the application of pesticides, including herbicides, on forest lands. Such permits, which have not yet been developed, may entail additional costs. However, we do not expect a disproportionate effect on Weyerhaeuser as compared to comparable operations of other forest landowners.
