NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

FOR THE QUARTERS AND YEAR-TO-DATE PERIODS ENDED SEPTEMBER 30, 2013 AND 2012

NOTE 1:BASIS OF PRESENTATION

We are a corporation that has elected to be taxed as a real estate investment trust (REIT). We expect to derive most of our REIT income from investments in timberlands, including the sale of standing timber 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 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.

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 single-family home building 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, 2012. Results of operations for interim periods should not be regarded as necessarily indicative of the results that may be expected for the full year.

RECLASSIFICATIONS

We have reclassified certain balances and results from the prior year to be consistent with our 2013 reporting. This makes year-to-year comparisons easier. Our reclassifications had no effect on net earnings or Weyerhaeuser shareholders’ interest. Our reclassifications record our variable interest entities assets and liabilities into their respective line items on our Consolidated Balance Sheet.

NOTE 2:LONGVIEW TIMBER PURCHASE

On July 23, 2013, we purchased 100 percent of the equity interests in Longview Timber LLC (Longview Timber) for $1.58 billion cash and assumed debt of $1.07 billion, for an aggregate purchase price of $2.65 billion. Longview Timber is a privately-held Delaware limited liability company engaged in the ownership and management of approximately 645,000 acres of timberlands primarily in Oregon and Washington. We believe Longview Timber has productive lands with favorable age class distribution that will provide us with optionality for harvest. Earnings, assets and liabilities from this business are reported as part of the Timberlands segment beginning in third quarter 2013.

Summarized unaudited pro forma information that presents combined amounts as if this acquisition occurred at the beginning of 2012, is as follows:

	QUARTER ENDED				YEAR-TO-DATE ENDED
DOLLAR AMOUNTS IN MILLIONS, EXCEPT PER-SHARE FIGURES	SEPTEMBER 2013		SEPTEMBER 2012		SEPTEMBER 2013		SEPTEMBER 2012

Earnings per share attributable to Weyerhaeuser common shareholders, basic and diluted	$	0.26	$	0.18	$	0.88	$	0.37

The following table summarizes the estimated fair values of identifiable assets acquired and liabilities assumed as of the acquisition date.

DOLLAR AMOUNTS IN MILLIONS	JULY 23, 2013
Current assets	$	46
Property and equipment	39
Timber and timberlands	2,654
Other assets	2
Total assets acquired	2,741
Current liabilities	10
Long-term debt	1,122
Other liabilities	5
Total liabilities assumed	1,137
Net assets acquired	$	1,604

The initial allocations of purchase price are recorded at the estimated fair value of assets acquired and liabilities assumed based upon the best information available to management. We are currently in the process of finalizing our valuations related to timberlands, certain pieces of property and their associated contracts. Our valuations will be finalized when certain information arranged to be obtained has been received and our review of that information has been completed.

In order to finance our purchase of Longview Timber, we issued the following:

• 29 million common shares on June 24, 2013, at the price of $27.75 per share for net proceeds of $781 million;

• 4.4 million common shares on July 8, 2013, at the price of $27.75 per share for net proceeds of $116 million, in connection with the exercise of an overallotment option; and

• 13.8 million of our 6.375 percent Mandatory Convertible Preference Shares, Series A, par value $1.00 and liquidation preference of $50.00 per share on June 24, 2013, for net proceeds of $669 million. Dividends will be payable on a cumulative basis when, as and if declared by our Board of Directors, at an annual rate of 6.375 percent on the liquidation preference. We may pay declared dividends in cash or, subject to certain limitations, in common shares or by delivery of any combination of cash and common shares on January 1, April 1, July 1 and October 1 of each year, commencing on October 1, 2013, through, and including, July 1, 2016. These shares will automatically convert on July 1, 2016 into between 1.5015 and 1.8018 of our common shares,

7

subject to anti-dilution adjustments. At any time prior to that date, holders may elect to convert each share into common shares at the minimum conversion rate of 1.5015 common shares, subject to anti-dilution adjustments.

For issuances of shares, excess of par value is recorded in "Other capital" in our Consolidated Balance Sheet.

Proceeds were used to finance the acquisition and pay related fees and expenses. We paid $11 million in fees related to a bridge loan in second quarter 2013. As of the close of the Longview Timber purchase, we did not use the loan and these fees were expensed in third quarter 2013, which is recorded in "Interest expense" in our Consolidated Statement of Operations.

We obtained additional debt financing in third and fourth quarter 2013 which was used to repay all of the assumed debt in fourth quarter 2013. See Note 9: Long-term Debt and Lines of Credit.

NOTE 3:BUSINESS SEGMENTS

We are principally engaged in growing and harvesting timber; manufacturing, distributing and selling forest products; and developing real estate and building single-family homes. 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 and single-family home building operations.

(1) Unallocated Items are gains or charges not related to or allocated to an individual operating segment. They include a portion of items such as: share-based compensation, pension and postretirement costs, foreign exchange transaction gains and losses associated with financing and the elimination of intersegment profit in inventory and the LIFO reserve.

NOTE 4:NET EARNINGS PER SHARE

Our basic earnings per share attributable to Weyerhaeuser shareholders were:

• $0.27 during third quarter and $0.89 during year-to-date 2013 and

• $0.22 during third quarter and $0.45 during year-to-date 2012.

Our diluted earnings per share attributable to Weyerhaeuser shareholders were:

• $0.27 during third quarter and $0.88 during year-to-date 2013 and

• $0.22 during third quarter and $0.45 during year-to-date 2012.

9

Basic earnings per share is net earnings available to common shareholders divided by the weighted average number of our outstanding common shares, including stock equivalent units where there is no circumstance under which those shares would not be issued.

Diluted earnings per share is net earnings 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,

• performance share units and

• preference shares.

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

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

Preference shares are evaluated for participation on a quarterly basis to determine whether two-class presentation is required. Preference shares are considered to be participating as of the financial reporting period end to the extent they would participate in dividends paid to common shareholders. Preference shares are not considered participating for the quarter and year-to-date periods ended September 30, 2013. Under the provisions of the two-class method, basic and diluted earnings per share would be presented for both preference and common shareholders.

SHARES EXCLUDED FROM DILUTIVE EFFECT

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.

We issued 13.8 million 6.375 percent Mandatory Convertible Preference Shares, Series A on June 24, 2013. We do not include these shares in our calculation of diluted earnings per share because they are antidilutive. See Note 2: Longview Timber Purchase.

NOTE 5:INVENTORIES

Forest Products inventories include raw materials, work-in-process and finished goods.

The LIFO – the last-in, first-out method – applies to major inventory products held at our U.S. domestic locations. We began to use the LIFO method for domestic products in the 1940s as required to conform with the tax method elected. Subsequent acquisitions of entities added new products under the FIFO - the first-in, first-out method – or moving average cost methods that have continued under those methods. The FIFO or moving average cost methods applies to the balance of our domestic raw material and product inventories as well as for all material and supply inventories and all foreign inventories. If we used FIFO for all inventories, our stated inventories would have been $109 million and $112 million higher as of September 30, 2013 and December 31, 2012, respectively.

During fourth quarter 2011, we ratified amendments to our postretirement medical and life insurance benefit plans for U.S. salaried employees that reduced or eliminated certain benefits that were available to both past and present employees. The company recognized a gain of $103 million in year-to-date 2012 due to these benefit changes. This gain is included in other operating income and reflected in the amortization of prior service credit in the table above. As of the end of second quarter 2012, the gain for the fourth quarter amendments had been fully recognized.

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. 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. During second quarter 2013, we recorded an increase in the fair value of the pension assets of $56 million and an increase to the projected benefit obligation of $55 million, as a result of changes in the census data. The net effect was a $1 million increase in the funded status as of December 31, 2012.

EXPECTED CONTRIBUTIONS AND BENEFIT PAYMENTS

We expect to make approximately$79 millionof required contributions to our Canadian registered and nonregistered pension plans in 2013. The decrease in the expectation was the result of the company electing to apply for Alberta Funding Relief effective December 31, 2012, for the plans registered in that province.

We also expect that in 2013 we will:

• make benefit payments of$19 millionon behalf of our U.S. nonqualified pension plans and

• make benefit payments of $37 million on behalf of our U.S. and Canadian other postretirement plans.

We donotanticipate making a contribution to our U.S. qualified pension plan for 2013.

NOTE 7:VARIABLE INTEREST ENTITIES

In second quarter 2013, we repaid a $162 million note and received $184 million related to one of our timber monetization special-purpose entities (SPEs) undertaken in 2003. Net proceeds were $22 million. As a result of dissolving one of our SPEs, the deferred tax liability related to our SPEs was reduced to $177 million as of June 30, 2013, compared to $240 million as of December 31, 2012. More information about these entities, which were formed in connection with the sale of nonstrategic timberlands in 2003, can be found in our annual reports on Form 10-K for 2012 and 2003.

NOTE 8:ACCRUED LIABILITIES

Forest Products accrued liabilities were comprised of the following:

NOTE 9:LONG-TERM DEBT AND LINES OF CREDIT

This note provides details about our:

• long-term debt,

• term loan credit facility,

• repayment of Longview Timber debt,

• revolving credit facility, and

• debt covenants.

Long-term debt

During September 2013, we issued notes totaling $500 million. The notes are unsecured and unsubordinated senior obligations bearing an interest rate of 4.625 percent due September 15, 2023. The net proceeds after deducting the discount, underwriting fees and issuance costs were $494 million and are included in "Cash and cash equivalents designated for the purchase of Longview Timber LLC and the repayment of their acquired debt" in our Consolidated Balance Sheet.

Term loan credit facility

During September 2013, we entered into a $550 million 7-year senior unsecured term loan credit facility maturing in September 2020. We had no borrowings under this facility at the end of the quarter. Subsequent to quarter end, we borrowed $550 million under this facility. Borrowings are at LIBOR plus a spread or at other interest rates mutually agreed upon between the borrower and the lending banks.

Repayment of Longview Timber debt

On October 15, 2013, we repaid the $1,118 million carrying value of the debt that we assumed in the acquisition of Longview Timber and related fees, expenses and premiums using the proceeds from the notes issued in third quarter 2013 and the borrowings from our term loan credit facility borrowed in fourth quarter 2013. A pretax charge of $25 million will also be included in our net interest expense in fourth quarter 2013, for early retirement premiums, unamortized debt issuance costs and other miscellaneous charges in connection with the early extinguishment of debt. See Note 2: Longview Timber Purchase.

Revolving credit facility

During September 2013, we entered into a new $1 billion 5-year senior unsecured revolving credit facility that expires in September 2018. This replaces a $1 billion revolving credit facility that was set to expire June 2015. Conditions of the line of credit include the following:

• The entire amount is available to Weyerhaeuser Company.

• $50 million of the amount is available to Weyerhaeuser Real Estate Company (WRECO).

• Neither of the entities is a guarantor of the borrowing of the other.

Borrowings are at LIBOR plus a spread or at other interest rates mutually agreed upon between the borrower and the lending banks. There were no net proceeds from the issuance of debt or from borrowings (repayments) under our available credit facilities in year-to-date 2013 or 2012.

Debt Covenants

As of September 30, 2013 Weyerhaeuser Company and WRECO were in compliance with all debt covenants. There have been no significant changes during year-to-date 2013 to our debt covenants presented in our 2012 Annual Report on Form 10-K.

NOTE 10:FAIR VALUE OF FINANCIAL INSTRUMENTS

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

	SEPTEMBER 30, 2013				DECEMBER 31, 2012
DOLLAR AMOUNTS IN MILLIONS	CARRYING  VALUE		FAIR VALUE (LEVEL 2)		CARRYING  VALUE		FAIR VALUE (LEVEL 2)
Long-term debt (including current maturities):
Forest Products	$	5,459	$	6,286	$	4,182	$	4,994
Real Estate	$	109	$	110	$	109	$	112

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.

Forest Products long-term debt increased primarily due to the assumption and issuance of debt related to the acquisition of Longview Timber. See Note: 2 Longview Timber Purchase and Note 9: Long-term Debt and Lines of Credit.

FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS

We believe that our other financial instruments, including cash and cash equivalents, 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 11: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.

2011 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. On August 23, 2013, the Court dismissed the claim for money damages, but the claim for injunctive relief remains active. The company believes that its pension plans have been consistently managed in full compliance with established fiduciary standards and is vigorously contesting the claim.

ENVIRONMENTAL MATTERS

Our environmental matters include:

• site remediation,

• asset retirement obligations, and

• regulation of air emission 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, 2013, our total accrual for future estimated remediation costs on the active Superfund sites and other sites for which we are responsible was approximately $30 million. These reserves are recorded in "Accrued liabilities" and "Other liabilities" in our Consolidated Balance Sheet. The accrual has not changed materially since the end of 2012.

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, cap and monitor landfills. As of September 30, 2013, our total accruals for these obligations was $56 million. These obligations are recorded in "Accrued liabilities" and "Other liabilities" in our Consolidated Balance Sheet. The accruals have not changed materially since the end of 2012.

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 2010, the EPA issued a final rule that would limit the growth in greenhouse gas emissions from new projects meeting certain emission thresholds. This rule, which would apply to our manufacturing operations on a project-by-project basis, originally included carbon dioxide from carbon-neutral biomass in the air permitting process. In 2011, the EPA issued a final rule deferring until mid-2014 greenhouse gas permitting requirements for carbon dioxide emissions from biomass while the EPA completed analysis and rulemaking on how biomass emissions should be treated. On July 12, 2013, the D.C Circuit Court of Appeals issued a decision to vacate the biomass deferral rule. The Court has not yet issued its mandate to the EPA and the EPA has not yet indicated how it may respond, so we are unable to predict the effect on our operations. However, more than 75 percent of energy for our operations is derived from biomass. If emissions from biomass are included in the air permitting process, it could significantly increase the burden and cost of the air permitting process.

At our Annual Meeting of Shareholders held on April 11, 2013, our shareholders approved the Weyerhaeuser Company 2013 Long-Term Incentive Plan (“2013 Plan”). Shareholders approved 10 million shares of common stock for issuance under the 2013 Plan. In addition, approximately 9 million shares authorized for issuance under our 2004 Long-Term Incentive Plan that have not been issued and are not subject to outstanding awards are available for issuance under the 2013 Plan. Our Board of Directors had previously adopted and approved the 2013 Plan, subject to shareholder approval.

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

18

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 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 2013 provision for income taxes is based on the current estimate of the annual effective tax rate. Our 2013 estimated annual effective tax rate for our TRS is31.2 percent, which is lower than the statutory federal tax rate primarily due to permanent tax deductions and lower foreign tax rates applicable to foreign earnings.

During third quarter 2012, as a result of reaching agreements with taxing authorities, we reduced our unrecognized tax benefits and recognized a tax provision reduction of $7 million.

There were no significant discrete items excluded from the calculation of our effective income tax rate for 2013.2012 items include:

DOLLAR AMOUNTS IN MILLIONS
First Quarter 2012:
Income taxes on postretirement plan amendment discussed in Note 6	$	(18	)
State income tax settlements	$	8
Second Quarter 2012:
Income taxes on postretirement plan amendment discussed in Note 6	$	(18	)
Income tax settlements	$	(3	)
Third Quarter 2012:
Income tax settlements	$	7

It is reasonably possible that up to $160 million in unrecognized tax benefits, primarily related to alternative fuel mixture credits, may be recognized within the next 12 months when tax examinations are expected to be completed.

NOTE 16:SUBSEQUENT EVENT

On June 16, 2013, we announced that our Board of Directors authorized the exploration of strategic alternatives with respect to Weyerhaeuser Real Estate Company (WRECO), our homebuilding and real estate development business. The Board indicated that it intended to consider a broad range of alternatives including, but not limited to, continuing to operate WRECO, or a merger, sale or spin-off of the business.

On November 4, 2013, we announced that we had entered into a transaction agreement dated as of November 3, 2013 with TRI Pointe Homes, Inc. (TRI Pointe). Pursuant to the transaction agreement, WRECO will be divested through a Reverse Morris Trust transaction and ultimately become a wholly owned subsidiary of TRI Pointe.

We intend to exclude certain assets of our real estate business from the transaction. The most significant of these entails a large master planned community located north of Las Vegas, Nevada with a current book value of approximately $360 million. Development of this property has been delayed pending further market recovery. Assuming we retain this asset, our strategy for development will likely vary significantly from the development plan under current WRECO ownership and could result in a substantial impairment to its book value in fourth quarter 2013 or prior to closing of the transaction.

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 euro and Canadian dollar and the relative value of the euro to the yen; and

• restrictions on international trade or tariffs imposed on imports.

21

RESULTS OF OPERATIONS

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

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

• Net contribution to earnings can be positive or negative and refers to earnings (loss) attributable to Weyerhaeuser shareholders before interest expense and income taxes.

In the following discussion, unless otherwise noted, references to increases or decreases in income and expense items, sales realizations, shipment volumes, and net contributions to earnings are based on the quarter and year-to-date periods ended September 30, 2013, compared to the quarter and year-to-date periods ended September 30, 2012.

Comparing Third Quarter 2013 with Third Quarter 2012

Net sales

Net sales increased $409 million – 23 percent – primarily due to the following:

• Wood Products segment sales increased $214 million, primarily due to higher sales realizations and higher sales volumes across most major product lines.

• Real Estate segment sales increased $94 million, primarily due to increased home closings and improved average prices for homes closed.

• Timberlands segment sales increased $86 million, primarily due to higher export and domestic log prices, increased sales volume and the purchase of Longview Timber.

Net earnings attributable to Weyerhaeuser common shareholders

Our net earnings attributable to Weyerhaeuser common shareholders increased $40 million – 34 percent – primarily from a $91 million increase in gross margin in our Wood Products, Timberlands and Real Estate segments. Our Wood Products and Timberlands segment increases were primarily due to higher sales realizations and sales volumes. Increased gross margin in our Real Estate segment was primarily due to increased single-family home closings.

22

This was partially offset by:

• a $27 million decrease in gross margin in our Cellulose Fibers segment, primarily due to lower sales realizations and higher manufacturing and maintenance related costs; and

• a $23 million increase in income taxes primarily due to higher income in our TRS in 2013 compared to 2012.

Comparing Year-to-Date 2013 with Year-to-Date 2012

Net sales

Net sales increased $1,214 million – 24 percent – primarily due to the following:

• Wood Products segment sales increased $857 million, primarily due to higher sales realizations and higher sales volumes across all major product lines.

• Timberlands segment sales increased $200 million, primarily due to higher export and domestic log prices, increased sales volume and the purchase of Longview Timber.

• Real Estate segment sales increased $124 million primarily due to increased home closings and improved average prices for homes closed.

• Cellulose Fibers segment sales increased $33 million primarily due to increased sales volumes.

Net earnings attributable to Weyerhaeuser common shareholders

Our net earnings attributable to Weyerhaeuser common shareholders increased $255 million primarily from a $490 million increase in gross margin in our Wood Products, Timberlands and Real Estate segments. Our Wood Products and Timberlands segment increases were primarily due to higher sales realizations and sales volumes. Increased gross margin in our Real Estate segment was primarily due to increased single-family home closings.

This was partially offset by:

• a $104 million increase in income taxes, primarily due to higher income in our TRS in 2013 compared to 2012; and

• a $103 million pretax gain recognized in 2012 related to a previously announced postretirement plan amendment.

(1) Significant dispositions of higher and better use timberland and some non-strategic timberlands are made through Forest Products subsidiaries.

(2) Products include logs, plywood and hardwood lumber harvested or produced by our international operations, primarily in South America.

On July 23, 2013, we purchased 100 percent of the equity interests in Longview Timber LLC (Longview Timber) for cash and assumed debt. The sales and net contribution to earnings of our acquired entity from the acquisition date to the end of the quarter are included in the West results of our Timberlands segment. Longview Timber was and continues to be a supplier to our Wood Products segment and those sales are shown in intersegment sales.

Comparing Third Quarter 2013 with Third Quarter 2012

Net sales – unaffiliated customers

Net sales to unaffiliated customers increased $86 million – 32 percent – primarily from the following:

• Western log sales increased $81 million due to higher export and domestic log prices and a 38 percent increase in sales volume as a result of increased export and domestic demand and the purchase of Longview Timber; and

• Southern log sales increased $6 million due to higher log prices and a 6 percent increase in sales volumes as the result of increased harvest levels in response to increased third party demand.

24

Intersegment sales

Intersegment sales increased $32 million – 20 percent – primarily from:

• a $27 million increase, primarily due to higher log prices in our legacy Western timberlands and the South and the purchase of Longview Timber; and

• a $5 million increase due to higher log prices and increased sales volumes in Canada.

Net contribution to earnings

Net contribution to earnings increased $38 million – 48 percent – primarily from:

• a $33 million increase due to higher log prices in our legacy Western timberlands and the South,

• a $16 million increase due to the purchase of Longview Timber and

• a $12 million increase due to higher sales volumes and demand for export and domestic logs in our legacy Western timberlands. Harvest levels increased 29 percent in our legacy Western timberlands.

The above items were partially offset by a $20 million increase in operating costs in our legacy Western timberlands primarily due to a higher mix of higher cost logs from internal and outside purchases.

Comparing Year-to-Date 2013 with Year-to-Date 2012

Net sales – unaffiliated customers

Comparing Third Quarter 2013 with Third Quarter 2012

Net sales

Net sales increased $15 million – 3 percent – primarily due to increased sales volumes of 7 percent for pulp, which was partially offset by decreased sales realizations of $13 per ton – 2 percent.

Net contribution to earnings

Net contribution to earnings decreased $31 million – 40 percent – primarily due to:

• a $14 million decrease in earnings, primarily due to decreased production and higher maintenance and contractor service costs, as third quarter 2013 had more maintenance outages;

• a $7 million increase in fiber and chemical costs;

• a $6 million decrease in pulp sales realizations; and

• a $6 million decrease in liquid packaging board sales realizations.

Comparing Year-to-Date 2013 with Year-to-Date 2012

Net sales

Net sales increased $33 million – 2 percent – primarily due to increased sales volumes of 6 percent for pulp, which was partially offset by decreased sales realizations of $19 per ton – 2 percent.

Net contribution to earnings

Net contribution to earnings decreased $27 million – 17 percent – primarily due to:

• a $26 million decrease in pulp sales realizations;

• a $22 million decrease in liquid packaging sales realizations; and

• a $13 million increase in other operating costs, including increased depreciation from the start up of our Poland facility in December 2012.

These decreases were partially offset by:

• an $18 million increase in earnings, primarily due to increased production and lower maintenance and contractor service costs, as 2013 had fewer maintenance outages; and

• a $16 million decrease in chemical and energy costs.

On June 16, 2013, we announced that our Board of Directors authorized the exploration of strategic alternatives with respect to Weyerhaeuser Real Estate Company (WRECO), our homebuilding and real estate development business. The Board indicated that it intended to consider a broad range of alternatives including, but not limited to, continuing to operate WRECO, or a merger, sale or spin-off of the business. On November 4, 2013, we announced that we had entered into a transaction agreement dated as of November 3, 2013 with TRI Pointe Homes, Inc. (TRI Pointe). Pursuant to the transaction agreement, WRECO will be divested through a Reverse Morris Trust transaction and ultimately become a wholly owned subsidiary of TRI Pointe. More information on this transaction can be found in Note 16: Subsequent Eventand on our Current Report on Form 8-K filed with the Securities and Exchange Commission on November 4, 2013.

31

Comparing Third Quarter 2013 with Third Quarter 2012

Net sales

Net sales increased $94 million – 41 percent – primarily due to:

• Single-family housing revenues increased $76 million. Home closing increased 25 percent from 615 in 2012 to 768 in 2013, with increased closings in most markets. The average price of homes closed increased 7 percent from $372,000 in 2012 to $397,000 in 2013. On a same store basis, prices have increased across all markets. Our average price on closings also increased regionally, except for California, where a change in the mix of open communities and the distribution of closings across our California markets resulted in a lower average price for the current quarter compared to one year ago.

• Revenues from land and lot sales increased $17 million. Land and lot sales are a routine part of our land development business but they do not occur evenly from period to period.

Net contribution to earnings

Net contribution to earnings increased $16 million, primarily due to:

• A $12 million increase in earnings from single-family home sales. Partially offsetting the benefit of higher closing volume and higher average prices was a decline in the average single-family gross margin to 22.3 percent in the current quarter compared to 23.3 percent in the prior year quarter, due to changes in mix. Changes in mix reflect changes in product lines (entry-level homes versus move-up products), changes in specific communities that are open from period to period, and changes in geographic markets where the closing occur.

• Earnings from land and lot sales increased $9 million.

These improvements were partially offset by an $8 million increase in selling, general and administrative expenses, including volume-related increases in selling costs and additional costs associated with new community openings.

Comparing Year-to-Date 2013 with Year-to-Date 2012

Net sales

Net sales increased $124 million – 19 percent – primarily due to an increase of $195 million in revenue from single-family home sales. Home closings increased 27 percent from 1,472 in 2012 to 1,867 in 2013. The average price of homes closed increased 7 percent from $374,000 in 2012 to $399,000 in 2013. On a same store basis, prices have increased across all markets. Our average price on closings also increased regionally, except for California, where a change in the mix of open communities and the distribution of closings across our California markets resulted in a lower average price for 2013 compared to 2012.

This was partially offset by a decrease of $70 million in revenue from land and lot sales. 2012 included the sale of a 3,200-acre master planned community in Houston, Texas. The 2013 land and lot sales were primarily residential lot sales and an acreage sale related to a school site.

Net contribution to earnings

Net contribution to earnings increased $23 million, primarily due to a $44 million increase in earnings from single-family home sales. In addition to the higher volume and higher average revenues, single-family gross margins improved to 21.4 percent in 2013 compared to 20.5 percent in 2012, reflecting changes in mix.

This improvement was partially offset by a $20 million increase in selling, general and administrative expenses, including volume-related increases in selling costs, additional costs associated with new community openings, higher employee-related costs associated with improved operating performance, and increased corporate allocations.

UNALLOCATED ITEMS

Unallocated Items are gains or charges not related to or allocated to an individual operating segment. They include a portion of items such as: share-based compensation, pension and postretirement costs, foreign exchange transaction gains and losses associated with financing and the elimination of intersegment profit in inventory and the LIFO reserve.

Unallocated Items included recognized gains of $103 million during first half 2012 related to a previously announced postretirement plan amendment. In third quarter 2013, we sold part of our investment in Liaison Technologies Inc. and recognized an $10 million pretax gain, which is recorded in "Interest income and other" in our Consolidated Statement of Operations.

INTEREST EXPENSE

Our net interest expense incurred was:

• $95 million during third quarter 2013 and $258 million during year-to-date 2013 and

• $87 million during third quarter 2012 and $260 million during year-to-date 2012.

Interest expense includes $11 million in fees related to a bridge loan we did not use in the acquisition of Longview Timber that was expensed in third quarter 2013. Excluding this item, interest expense is lower due to a lower level of average debt during the year.

On October 15, 2013, we repaid the $1,118 million carrying value of the debt that we assumed in the acquisition of Longview Timber. We recognized a pretax charge of $25 million that will be included in our net interest expense in fourth quarter 2013, for early retirement premiums, unamortized debt issuance costs and other miscellaneous charges in connection with the early extinguishment of debt. See Note 2: Longview Timber Purchase.

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 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 2013 provision for income taxes is based on the current estimate of the annual effective tax rate. Our 2013 estimated annual effective tax rate for our TRS is31.2 percent, which is lower than the statutory federal tax rate primarily due to permanent tax deductions and lower foreign tax rates applicable to foreign earnings.

33

During third quarter 2012, as a result of reaching agreements with taxing authorities, we reduced our unrecognized tax benefits and recognized a tax provision reduction of $7 million.

There were no significant discrete items excluded from the calculation of our effective income tax rate for 2013.2012 items include:

DOLLAR AMOUNTS IN MILLIONS
First Quarter 2012:
Income taxes on postretirement plan amendment discussed in Note 6	$	(18	)
State income tax settlements	$	8
Second Quarter 2012:
Income taxes on postretirement plan amendment discussed in Note 6	$	(18	)
Income tax settlements	$	(3	)
Third Quarter 2012:
Income tax settlements	$	7

It is reasonably possible that up to $160 million in unrecognized tax benefits, primarily related to alternative fuel mixture credits, may be recognized within the next 12 months when tax examinations are expected to be completed.

LIQUIDITY AND CAPITAL RESOURCES

We are committed to maintaining a sound and conservative capital structure that 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 timing of debt maturities.

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

Consolidated net cash provided by our operations was:

• $656 million in 2013 and

• $329 million in 2012.

Comparing 2013 with 2012

Net cash from operations increased $327 million in 2013 as compared with 2012, primarily due to a $1,135 million increase in cash received from customers partially offset by a $817 million increase in cash paid to employees, suppliers and others as sales and production increased in our Wood Products, Timberlands and Real Estate segments. Receivables, primarily in our Wood Products segment, increased significantly in 2013 compared to 2012 as sales increased.

34

Expected Pension Contributions and Benefit Payments

We expect to make approximately$79 millionof required contributions to our Canadian registered and nonregistered pension plans in 2013. The decrease in the expectation was the result of the company electing to apply for Alberta Funding Relief effective December 31, 2012, for the plans registered in that province.

We also expect that in 2013 we will:

• make benefit payments of$19 millionon behalf of our U.S. nonqualified pension plans and

• make benefit payments of $37 million on behalf of our U.S. and Canadian other postretirement plans.

We donotanticipate making a contribution to our U.S. qualified pension plan for 2013.

CASH FROM INVESTING ACTIVITIES

Consolidated net cash used by investing activities was:

• $1,718 million in 2013 and

• $281 million in 2012.

Longview Timber Purchase

On July 23, 2013, we purchased 100 percent of the equity interests in Longview Timber LLC (Longview Timber) for $1.58 billion cash and assumed debt of $1.07 billion, for an aggregate purchase price of $2.65 billion. More information can be found in Note 2: Longview Timber Purchaseand the"Cash from financing activities" section below.

Summary of Capital Spending by Business Segment

	YEAR-TO-DATE ENDED
DOLLAR AMOUNTS IN MILLIONS	SEPTEMBER 2013		SEPTEMBER 2012
Timberlands	$	52	$	44
Wood Products	52		37
Cellulose Fibers	62		134
Real Estate	9		2
Unallocated Items	4		2
Total	$	179	$	219

We anticipate that our net capital expenditures for 2013 – excluding acquisitions – to approximate $300 million.

Variable Interest Entities

In second quarter 2013, we repaid a $162 million note and received $184 million related to one of our timber monetization special-purpose entities (SPEs) undertaken in 2003. Net proceeds were $22 million. More information about these entities, which were formed in connection with the sale of nonstrategic timberlands in 2003, can be found in our annual reports on Form 10-K for 2012 and 2003.

Equity Affiliates

In third quarter 2013, we sold part of our investment in Liaison Technologies Inc. and received $10 million in cash, which is recorded in "Other" in the "Cash flows from investing activities" in our Consolidated Statement of Cash Flows.

35

CASH FROM FINANCING ACTIVITIES

Consolidated net cash provided by (used in) financing activities was:

• $1,561 million in 2013 and

• $(393) million in 2012.

Longview Timber Purchase

In order to finance our purchase of Longview Timber, see Note 2: Longview Timber Purchase, we issued the following:

• 29 million common shares on June 24, 2013, at the price of $27.75 per share for net proceeds of $781 million;

• 4.4 million common shares on July 8, 2013, at the price of $27.75 per share for net proceeds of $116 million, in connection with the exercise of an overallotment option; and

• 13.8 million of our 6.375 percent Mandatory Convertible Preference Shares, Series A, par value $1.00 and liquidation preference of $50.00 per share on June 24, 2013, for net proceeds of $669 million.

We paid $11 million in fees related to a bridge loan in second quarter 2013. which is recorded in "Other" in the "Cash flows from financing activities" in our Consolidated Statement of Cash Flows. As of the close of the Longview Timber purchase, we did not use the loan and these fees were expensed in third quarter 2013.

In order to repay the debt that we assumed in the acquisition of Longview Timber, in third quarter 2013 we issued $500 million of 4.625 percent notes due September 15, 2023. The net proceeds after deducting the discount, underwriting fees and issuance costs were $494 million and are included in "Cash and cash equivalents designated for the purchase of Longview Timber LLC and the repayment of their acquired debt" in our Consolidated Balance Sheet.

During September 2013, we entered into a $550 million 7-year senior unsecured term loan credit facility maturing in September 2020. We had no borrowings under this facility at the end of the quarter. Subsequent to quarter end, we borrowed $550 million under this facility. Borrowings are at LIBOR plus a spread or at other interest rates mutually agreed upon between the borrower and the lending banks.

On October 15, 2013, we repaid the $1,118 million carrying value of the debt that we assumed in the acquisition of Longview Timber and related fees, expenses and premiums using the proceeds from the notes issued in third quarter 2013 and the borrowings from our term loan credit facility borrowed in fourth quarter 2013. A pretax charge of $25 million will also be included in our net interest expense in fourth quarter 2013, for early retirement premiums, unamortized debt issuance costs and other miscellaneous charges in connection with the early extinguishment of debt. See Note 2: Longview Timber Purchase.

Debt (excluding debt related to Longview Timber Purchase)

We repaid debt of:

• $340 million in year-to-date 2013 and

• $187 million in year-to-date 2012 (including $176 million of Real Estate debt maturities).

There are no Forest Products debt maturities in the next 12 months. Real Estate debt maturities in the next 12 months are:

• $69 million in fourth quarter 2013 and

• $15 million in third quarter 2014.

There are no maturities in first or second quarter 2014.

36

Revolving credit facility

During September 2013, we entered into a new $1 billion 5-year senior unsecured revolving credit facility that expires in September 2018. This replaces a $1 billion revolving credit facility that was set to expire June 2015. Conditions of the line of credit include the following:

• The entire amount is available to Weyerhaeuser Company.

• $50 million of the amount is available to Weyerhaeuser Real Estate Company (WRECO).

• Neither of the entities is a guarantor of the borrowing of the other.

Borrowings are at LIBOR plus a spread or at other interest rates mutually agreed upon between the borrower and the lending banks. There were no net proceeds from the issuance of debt or from borrowings (repayments) under our available credit facility in year-to-date 2013 or 2012.

Debt Covenants

As of September 30, 2013 Weyerhaeuser Company and WRECO were in compliance with all debt covenants. There have been no significant changes during year-to-date 2013 to our debt covenants presented in our 2012 Annual Report on Form 10-K.

Credit Ratings

On April 22, 2013, Moody's Investors Service upgraded our senior unsecured note rating to Baa3 from Ba1 and changed their outlook to stable.

Option Exercises

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

• $141 million in 2013 and

• $73 million in 2012.

The increase in exercises of stock options is primarily due to the increase in our average stock price. In year-to-date 2013, our average stock price was $29.63, a 36 percent increase, compared to $21.83 during year-to-date 2012.

Paying dividends and repurchasing stock

We paid dividends to common shareholders of:

• $330 million in 2013 and

• $242 million in 2012.

The increase in dividends paid is primarily due to the increase in our quarterly dividend from 15 cents per share to 17 cents per share in November 2012, to 20 cents per share in April 2013 and to 22 cents per share in August 2013, a 47 percent increase in our quarterly dividend.

On August 24, 2013, our Board of Directors declared a dividend of 85.88 cents per share on our 6.375 percent Mandatory Convertible Preference Shares, Series A, payable on October 1, 2013, to shareholders of record at the close of business September 15, 2013.

On October 9, 2013, our Board of Directors declared a dividend of 22 cents per share on our common stock payable on November 27, 2013 to shareholders of record at the close of business November 1, 2013. Additionally, our Board of Directors declared a dividend of 79.69 cents per share on our 6.375 percent Mandatory Convertible Preference Shares, Series A, payable on January 1, 2014, to shareholders of record at the close of business December 15, 2013.

During September 2013, we issued notes totaling $500 million. The notes are unsecured and unsubordinated senior obligations bearing an interest rate of 4.625 percent due September 15, 2023. The net proceeds after deducting the discount, underwriting fees and issuance costs were $494 million and are included in "Cash and cash equivalents designated for the purchase of Longview Timber LLC and the repayment of their acquired debt" in our Consolidated Balance Sheet.

Term loan credit facility

During September 2013, we entered into a $550 million 7-year senior unsecured term loan credit facility maturing in September 2020. We had no borrowings under this facility at the end of the quarter. Subsequent to quarter end, we borrowed $550 million under this facility. Borrowings are at LIBOR plus a spread or at other interest rates mutually agreed upon between the borrower and the lending banks.

Repayment of Longview Timber debt

On October 15, 2013, we repaid the $1,118 million carrying value of the debt that we assumed in the acquisition of Longview Timber and related fees, expenses and premiums using the proceeds from the notes issued in third quarter 2013 and the borrowings from our term loan credit facility borrowed in fourth quarter 2013. A pretax charge of $25 million will also be included in our net interest expense in fourth quarter 2013, for early retirement premiums, unamortized debt issuance costs and other miscellaneous charges in connection with the early extinguishment of debt. See Note 2: Longview Timber Purchase.

Revolving credit facility

During September 2013, we entered into a new $1 billion 5-year senior unsecured revolving credit facility that expires in September 2018. This replaces a $1 billion revolving credit facility that was set to expire June 2015. Conditions of the line of credit include the following:

• The entire amount is available to Weyerhaeuser Company.

• $50 million of the amount is available to Weyerhaeuser Real Estate Company (WRECO).

• Neither of the entities is a guarantor of the borrowing of the other.

Borrowings are at LIBOR plus a spread or at other interest rates mutually agreed upon between the borrower and the lending banks. There were no net proceeds from the issuance of debt or from borrowings (repayments) under our available credit facilities in year-to-date 2013 or 2012.

Debt Covenants

As of September 30, 2013 Weyerhaeuser Company and WRECO were in compliance with all debt covenants. There have been no significant changes during year-to-date 2013 to our debt covenants presented in our 2012 Annual Report on Form 10-K.

LONGVIEW TIMBER PURCHASE

Business Combinations [Abstract]

LONGVIEW TIMBER PURCHASE

LONGVIEW TIMBER PURCHASE

On July 23, 2013, we purchased 100 percent of the equity interests in Longview Timber LLC (Longview Timber) for $1.58 billion cash and assumed debt of $1.07 billion, for an aggregate purchase price of $2.65 billion. Longview Timber is a privately-held Delaware limited liability company engaged in the ownership and management of approximately 645,000 acres of timberlands primarily in Oregon and Washington. We believe Longview Timber has productive lands with favorable age class distribution that will provide us with optionality for harvest. Earnings, assets and liabilities from this business are reported as part of the Timberlands segment beginning in third quarter 2013.

Summarized unaudited pro forma information that presents combined amounts as if this acquisition occurred at the beginning of 2012, is as follows:

	QUARTER ENDED				YEAR-TO-DATE ENDED
DOLLAR AMOUNTS IN MILLIONS, EXCEPT PER-SHARE FIGURES	SEPTEMBER 2013		SEPTEMBER 2012		SEPTEMBER 2013		SEPTEMBER 2012
Net sales	$	2,191	$	1,813	$	6,390	$	5,192
Net earnings attributable to Weyerhaeuser common shareholders	$	153	$	104	$	514	$	214
Earnings per share attributable to Weyerhaeuser common shareholders, basic and diluted	$	0.26	$	0.18	$	0.88	$	0.37

The following table summarizes the estimated fair values of identifiable assets acquired and liabilities assumed as of the acquisition date.

DOLLAR AMOUNTS IN MILLIONS	JULY 23, 2013
Current assets	$	46
Property and equipment	39
Timber and timberlands	2,654
Other assets	2
Total assets acquired	2,741
Current liabilities	10
Long-term debt	1,122
Other liabilities	5
Total liabilities assumed	1,137
Net assets acquired	$	1,604

The initial allocations of purchase price are recorded at the estimated fair value of assets acquired and liabilities assumed based upon the best information available to management. We are currently in the process of finalizing our valuations related to timberlands, certain pieces of property and their associated contracts. Our valuations will be finalized when certain information arranged to be obtained has been received and our review of that information has been completed.

In order to finance our purchase of Longview Timber, we issued the following:

• 29 million common shares on June 24, 2013, at the price of $27.75 per share for net proceeds of $781 million;

• 4.4 million common shares on July 8, 2013, at the price of $27.75 per share for net proceeds of $116 million, in connection with the exercise of an overallotment option; and

• 13.8 million of our 6.375 percent Mandatory Convertible Preference Shares, Series A, par value $1.00 and liquidation preference of $50.00 per share on June 24, 2013, for net proceeds of $669 million. Dividends will be payable on a cumulative basis when, as and if declared by our Board of Directors, at an annual rate of 6.375 percent on the liquidation preference. We may pay declared dividends in cash or, subject to certain limitations, in common shares or by delivery of any combination of cash and common shares on January 1, April 1, July 1 and October 1 of each year, commencing on October 1, 2013, through, and including, July 1, 2016. These shares will automatically convert on July 1, 2016 into between 1.5015 and 1.8018 of our common shares, subject to anti-dilution adjustments. At any time prior to that date, holders may elect to convert each share into common shares at the minimum conversion rate of 1.5015 common shares, subject to anti-dilution adjustments.

For issuances of shares, excess of par value is recorded in "Other capital" in our Consolidated Balance Sheet.

Proceeds were used to finance the acquisition and pay related fees and expenses. We paid $11 million in fees related to a bridge loan in second quarter 2013. As of the close of the Longview Timber purchase, we did not use the loan and these fees were expensed in third quarter 2013, which is recorded in "Interest expense" in our Consolidated Statement of Operations.

We obtained additional debt financing in third and fourth quarter 2013 which was used to repay all of the assumed debt in fourth quarter 2013. See Note 9: Long-term Debt and Lines of Credit.

SUBSEQUENT EVENT

SUBSEQUENT EVENT

On June 16, 2013, we announced that our Board of Directors authorized the exploration of strategic alternatives with respect to Weyerhaeuser Real Estate Company (WRECO), our homebuilding and real estate development business. The Board indicated that it intended to consider a broad range of alternatives including, but not limited to, continuing to operate WRECO, or a merger, sale or spin-off of the business.

On November 4, 2013, we announced that we had entered into a transaction agreement dated as of November 3, 2013 with TRI Pointe Homes, Inc. (TRI Pointe). Pursuant to the transaction agreement, WRECO will be divested through a Reverse Morris Trust transaction and ultimately become a wholly owned subsidiary of TRI Pointe.

We intend to exclude certain assets of our real estate business from the transaction. The most significant of these entails a large master planned community located north of Las Vegas, Nevada with a current book value of approximately $360 million. Development of this property has been delayed pending further market recovery. Assuming we retain this asset, our strategy for development will likely vary significantly from the development plan under current WRECO ownership and could result in a substantial impairment to its book value in fourth quarter 2013 or prior to closing of the transaction.

FAIR VALUE OF FINANCIAL INSTRUMENTS

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

DOLLAR AMOUNTS IN MILLIONS	CARRYING  VALUE		FAIR VALUE (LEVEL 2)		CARRYING  VALUE		FAIR VALUE (LEVEL 2)

Real Estate	$	109	$	110	$	109	$	112

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.

Forest Products long-term debt increased primarily due to the assumption and issuance of debt related to the acquisition of Longview Timber. See Note: 2 Longview Timber Purchase and Note 9: Long-term Debt and Lines of Credit.

FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS

We believe that our other financial instruments, including cash and cash equivalents, 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.

Earnings Per Share, Basic and Diluted [Abstract]

Earnings Per Share, Policy

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

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

Preference shares are evaluated for participation on a quarterly basis to determine whether two-class presentation is required. Preference shares are considered to be participating as of the financial reporting period end to the extent they would participate in dividends paid to common shareholders. Preference shares are not considered participating for the quarter and year-to-date periods ended September 30, 2013. Under the provisions of the two-class method, basic and diluted earnings per share would be presented for both preference and common shareholders.

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). 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 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.

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 single-family home building 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, 2012. Results of operations for interim periods should not be regarded as necessarily indicative of the results that may be expected for the full year.

RECLASSIFICATIONS

We have reclassified certain balances and results from the prior year to be consistent with our 2013 reporting. This makes year-to-year comparisons easier. Our reclassifications had no effect on net earnings or Weyerhaeuser shareholders’ interest. Our reclassifications record our variable interest entities assets and liabilities into their respective line items on our Consolidated Balance Sheet.

During fourth quarter 2011, we ratified amendments to our postretirement medical and life insurance benefit plans for U.S. salaried employees that reduced or eliminated certain benefits that were available to both past and present employees. The company recognized a gain of $103 million in year-to-date 2012 due to these benefit changes. This gain is included in other operating income and reflected in the amortization of prior service credit in the table above. As of the end of second quarter 2012, the gain for the fourth quarter amendments had been fully recognized.

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. 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. During second quarter 2013, we recorded an increase in the fair value of the pension assets of $56 million and an increase to the projected benefit obligation of $55 million, as a result of changes in the census data. The net effect was a $1 million increase in the funded status as of December 31, 2012.

EXPECTED CONTRIBUTIONS AND BENEFIT PAYMENTS

We expect to make approximately$79 millionof required contributions to our Canadian registered and nonregistered pension plans in 2013. The decrease in the expectation was the result of the company electing to apply for Alberta Funding Relief effective December 31, 2012, for the plans registered in that province.

We also expect that in 2013 we will:

• make benefit payments of$19 millionon behalf of our U.S. nonqualified pension plans and

• make benefit payments of $37 million on behalf of our U.S. and Canadian other postretirement plans.

We donotanticipate making a contribution to our U.S. qualified pension plan for 2013.

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 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 2013 provision for income taxes is based on the current estimate of the annual effective tax rate. Our 2013 estimated annual effective tax rate for our TRS is31.2 percent, which is lower than the statutory federal tax rate primarily due to permanent tax deductions and lower foreign tax rates applicable to foreign earnings.

During third quarter 2012, as a result of reaching agreements with taxing authorities, we reduced our unrecognized tax benefits and recognized a tax provision reduction of $7 million.

There were no significant discrete items excluded from the calculation of our effective income tax rate for 2013.2012 items include:

DOLLAR AMOUNTS IN MILLIONS
First Quarter 2012:
Income taxes on postretirement plan amendment discussed in Note 6	$	(18	)

Second Quarter 2012:
Income taxes on postretirement plan amendment discussed in Note 6	$	(18	)
Income tax settlements	$	(3	)
Third Quarter 2012:
Income tax settlements	$	7

It is reasonably possible that up to $160 million in unrecognized tax benefits, primarily related to alternative fuel mixture credits, may be recognized within the next 12 months when tax examinations are expected to be completed.

The LIFO – the last-in, first-out method – applies to major inventory products held at our U.S. domestic locations. We began to use the LIFO method for domestic products in the 1940s as required to conform with the tax method elected. Subsequent acquisitions of entities added new products under the FIFO - the first-in, first-out method – or moving average cost methods that have continued under those methods. The FIFO or moving average cost methods applies to the balance of our domestic raw material and product inventories as well as for all material and supply inventories and all foreign inventories. If we used FIFO for all inventories, our stated inventories would have been $109 million and $112 million higher as of September 30, 2013 and December 31, 2012, respectively.

NET EARNINGS PER SHARE

NET EARNINGS PER SHARE

NET EARNINGS PER SHARE

Our basic earnings per share attributable to Weyerhaeuser shareholders were:

• $0.27 during third quarter and $0.89 during year-to-date 2013 and

• $0.22 during third quarter and $0.45 during year-to-date 2012.

Our diluted earnings per share attributable to Weyerhaeuser shareholders were:

• $0.27 during third quarter and $0.88 during year-to-date 2013 and

• $0.22 during third quarter and $0.45 during year-to-date 2012.

Basic earnings per share is net earnings available to common shareholders divided by the weighted average number of our outstanding common shares, including stock equivalent units where there is no circumstance under which those shares would not be issued.

Diluted earnings per share is net earnings 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,

• performance share units and

• preference shares.

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

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

Preference shares are evaluated for participation on a quarterly basis to determine whether two-class presentation is required. Preference shares are considered to be participating as of the financial reporting period end to the extent they would participate in dividends paid to common shareholders. Preference shares are not considered participating for the quarter and year-to-date periods ended September 30, 2013. Under the provisions of the two-class method, basic and diluted earnings per share would be presented for both preference and common shareholders.

SHARES EXCLUDED FROM DILUTIVE EFFECT

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.

We issued 13.8 million 6.375 percent Mandatory Convertible Preference Shares, Series A on June 24, 2013. We do not include these shares in our calculation of diluted earnings per share because they are antidilutive. See Note 2: Longview Timber Purchase.

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.

2011 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. On August 23, 2013, the Court dismissed the claim for money damages, but the claim for injunctive relief remains active. The company believes that its pension plans have been consistently managed in full compliance with established fiduciary standards and is vigorously contesting the claim.

ENVIRONMENTAL MATTERS

Our environmental matters include:

• site remediation,

• asset retirement obligations, and

• regulation of air emission 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, 2013, our total accrual for future estimated remediation costs on the active Superfund sites and other sites for which we are responsible was approximately $30 million. These reserves are recorded in "Accrued liabilities" and "Other liabilities" in our Consolidated Balance Sheet. The accrual has not changed materially since the end of 2012.

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, cap and monitor landfills. As of September 30, 2013, our total accruals for these obligations was $56 million. These obligations are recorded in "Accrued liabilities" and "Other liabilities" in our Consolidated Balance Sheet. The accruals have not changed materially since the end of 2012.

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 2010, the EPA issued a final rule that would limit the growth in greenhouse gas emissions from new projects meeting certain emission thresholds. This rule, which would apply to our manufacturing operations on a project-by-project basis, originally included carbon dioxide from carbon-neutral biomass in the air permitting process. In 2011, the EPA issued a final rule deferring until mid-2014 greenhouse gas permitting requirements for carbon dioxide emissions from biomass while the EPA completed analysis and rulemaking on how biomass emissions should be treated. On July 12, 2013, the D.C Circuit Court of Appeals issued a decision to vacate the biomass deferral rule. The Court has not yet issued its mandate to the EPA and the EPA has not yet indicated how it may respond, so we are unable to predict the effect on our operations. However, more than 75 percent of energy for our operations is derived from biomass. If emissions from biomass are included in the air permitting process, it could significantly increase the burden and cost of the air permitting process.

VARIABLE INTEREST ENTITIES

In second quarter 2013, we repaid a $162 million note and received $184 million related to one of our timber monetization special-purpose entities (SPEs) undertaken in 2003. Net proceeds were $22 million. As a result of dissolving one of our SPEs, the deferred tax liability related to our SPEs was reduced to $177 million as of June 30, 2013, compared to $240 million as of December 31, 2012. More information about these entities, which were formed in connection with the sale of nonstrategic timberlands in 2003, can be found in our annual reports on Form 10-K for 2012 and 2003.
