NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

FOR THE QUARTERS ENDED MARCH 31, 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. The reclassifications include where we report the elimination of intersegment profit on inventory and the LIFO reserve. Previously these company-level adjustments were recorded in the business segments and are now recorded in Unallocated Items. This provides a better understanding of business operating results.

NOTE 2: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.

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

	QUARTER ENDED

Income taxes	(41		)	15
Net earnings attributable to Weyerhaeuser common shareholders	$	144		$	41

(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.

7

NOTE 3:NET EARNINGS PER SHARE

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

• $0.26 during first quarter 2013; and

• $0.08 during first quarter 2012.

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

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

• weighted average number of our outstanding common shares and

• the effect of our outstanding dilutive potential common shares.

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.

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.

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

The LIFO – the last-in, first-out method – inventory reserve applies to major inventory products held at our U.S. domestic locations. These inventory products include grade and fiber logs, chips, lumber, plywood, oriented strand board, pulp and paperboard.

NOTE 5:PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

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

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 $52 million in first quarter 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.

FAIR VALUE OF PENSION PLAN ASSETS

As disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012, the value reported for our pension plan assets at the end of 2012 was estimated. Additional information regarding the year-end values generally becomes available to us during the first half of the following year. We expect to complete the valuation of our pension plan assets during second quarter 2013. The final adjustments could affect net pension periodic benefit cost.

EXPECTED CONTRIBUTIONS AND BENEFIT PAYMENTS

As disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012, in 2013 we expect to:

• make approximately$88 millionof required contributions to our Canadian registered and nonregistered pension plans in 2013;

• make benefit payments of$19 millionto our U.S. nonqualified pension plans; and

• make benefit payments of $37 millionrelated to our U.S. and Canadian other postretirement plans.

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

NOTE 6:ACCRUED LIABILITIES

Forest Products accrued liabilities were comprised of the following:

DOLLAR AMOUNTS IN MILLIONS	MARCH 31, 2013		DECEMBER 31, 2012

Customer rebates and volume discounts	34		44
Deferred income	54		60
Other	97		88
Total	$	531	$	561

NOTE 7:FAIR VALUE OF FINANCIAL INSTRUMENTS

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

	MARCH 31, 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	$	4,026	$	4,920	$	4,182	$	4,994
Real Estate	$	109	$	112	$	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.

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 8:LEGAL PROCEEDINGS, COMMITMENTS AND CONTINGENCIES

This note provides details about our:

• legal proceedings and

• environmental matters.

10

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.

ENVIRONMENTAL MATTERS

Our environmental matters include:

• site remediation and

• asset retirement obligations.

Site Remediation

Under the Comprehensive Environmental Response Compensation and Liability Act – commonly known as the Superfund – and similar state laws, we:

• are a party to various proceedings related to the cleanup of hazardous waste sites and

• have been notified that we may be a potentially responsible party related to the cleanup of other hazardous waste sites for which proceedings have not yet been initiated.

As of March 31, 2013, our total accrual for future estimated remediation costs on the active Superfund sites and other sites for which we are responsible was approximately $31 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 March 31, 2013, our total accruals for these obligations was $65 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.

NOTE 10:SHARE-BASED COMPENSATION

In first quarter 2013, we granted 1,902,816 stock options, 707,305 restricted stock units and 346,107 performance share units. In addition, 442,928 outstanding restricted stock units and 157,386 outstanding performance share units vested during first quarter 2013. A total of 4,180,264 shares of common stock were issued as a result of restricted stock unit vesting, performance share unit vesting and stock option exercises.

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.

NOTE 12: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, excluding discrete items, is34.7 percent.

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

FORWARD-LOOKING STATEMENTS

This report contains statements concerning our future results and performance that are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements:

• are based on various assumptions we make and

• may not be accurate because of risks and uncertainties surrounding the assumptions that we make.

Factors listed in this section – as well as other factors not included – may cause our actual results to differ significantly from our forward-looking statements. There is no guarantee that any of the events anticipated by our forward-looking statements will occur. Or if any of the events occur, there is no guarantee what effect they will have on our operations or financial condition.

We will not update our forward-looking statements after the date of this report.

FORWARD-LOOKING TERMINOLOGY

Some forward-looking statements discuss our plans, strategies and intentions. They use words such as expects, may, will, believes, should, approximately, anticipates, estimates, and plans. In addition, these words may use the positive or negative or other variations of those terms.

STATEMENTS

We make forward-looking statements of our expectations regarding second quarter 2013, including:

• improved selling prices for Western domestic and export logs, slightly lower fee harvest volumes, flat realization and somewhat higher fee harvest volumes in the South, seasonally higher silviculture expenses, somewhat higher earnings from dispositions of non-strategic timberlands and comparable earnings in our Timberlands segment excluding disposition of non-strategic timberlands;

• higher sales volumes across all product lines, slightly higher sales realization for engineered wood products, potential softening in prices for lumber and oriented strand board, slightly higher log costs, improved operating rates and comparable earnings in our Wood Products segment;

• slightly higher pulp price realizations, lower maintenance costs, lower fiber and energy costs and significantly higher earnings in our Cellulose Fiber segment; and

• seasonally increased home closings to approximately 600 single-family homes, slight decline in average price of homes closed due to mix, average margins comparable to first quarter 2013, higher selling-related expenses due to additional closing volume and a slight profit from single-family homebuilding in our Real Estate segment.

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

• the economy;

• regulations;

• adverse litigation outcomes and the adequacy of reserves;

• changes in accounting principles;

• changes in accounting principles; 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 euro and Canadian dollar and the relative value of the euro and yen; and

• restrictions on international trade or tariffs imposed on imports.

17

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 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 ended March 31, 2013, compared to the quarter ended March 31, 2012.

CONSOLIDATED RESULTS

How We Did in First Quarter 2013

NET SALES / OPERATING INCOME / NET EARNINGS – WEYERHAEUSER COMPANY

Here is a comparison of net sales, operating income and net earnings for the quarters ended March 31, 2013 and 2012:

	QUARTER ENDED				AMOUNT OF CHANGE
DOLLAR AMOUNTS IN MILLIONS, EXCEPT PER-SHARE FIGURES	MARCH 2013		MARCH 2012		2013 VS. 2012

Net earnings per share attributable to Weyerhaeuser common shareholders, basic and diluted	$	0.26	$	0.08	$	0.18

Comparing First Quarter 2013 with First Quarter 2012

Net sales

Net sales increased $457 million – 31 percent – primarily due to the following:

• Wood Products segment sales increased $354 million, primarily due to higher sales volumes across all major product lines and improved selling prices for lumber, oriented strand board (OSB) and plywood.

• Real Estate segment sales increased $59 million primarily due to increased home closings and improved average prices for homes closed.

• Timberlands segment sales increased $43 million, primarily due to higher export and domestic log prices and increased sales volume.

Net earnings attributable to Weyerhaeuser common shareholders

Our net earnings attributable to Weyerhaeuser common shareholders increased $103 million – 251 percent – primarily from a $214 million increase in gross margin in our Wood Products segment due to higher lumber, OSB and plywood price realizations. This increase was partially offset by:

• a $56 million increase in income taxes primarily due to higher income in our TRS in 2013 compared to 2012; and

• a $52 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.

Comparing First Quarter 2013 with First Quarter 2012

Net sales – unaffiliated customers

Net sales to unaffiliated customers increased $43 million – 17 percent – primarily from the following:

• Western log sales increased $47 million due to higher export and domestic log prices and a 28 percent increase in sales volume as a result of increased export and domestic demand.

• Southern log sales increased $11 million due to higher log prices and a 14 percent increase in sales volumes as the result of increased harvest levels in response to increased third party demand.

Intersegment sales

Intersegment sales increased $34 million – 18 percent – primarily from:

• a $19 million increase due to higher log prices and increased sales volumes in Canada; and

• a $15 million increase primarily due to higher log prices in the West and South.

19

Net contribution to earnings

Net contribution to earnings increased $34 million – 49 percent – primarily from:

• a $27 million increase due to higher log prices in the West and South; and

• an $11 million increase due to higher sales volumes and demand for export and domestic logs in the West; harvest levels increased 19 percent in the West.

Our Outlook for Second Quarter 2013

Excluding dispositions of non-strategic timberlands, we expect earnings from the segment to be comparable to first quarter. We anticipate improved selling prices for Western domestic and export logs, offset by seasonally higher silviculture expenses. Earnings from disposition of non-strategic timberlands should increase somewhat.

20

Overall performance in our Wood Products segment improved year over year. We continue to focus on reducing costs and increasing revenues by broadening our customer base; introducing new products; growing our specialty, as well as commodity building products business; and improving our operational capabilities. These improvement efforts and better market conditions, have resulted in higher production rates in all primary product lines.

Comparing FirstQuarter 2013 with First Quarter 2012

Net sales

Net sales increased $354 million – 56 percent – primarily from the following:

• Structural lumber shipment volumes increased 9 percent and average price realizations increased 41 percent.

• OSB shipment volumes increased 16 percent and average price realizations increased 82 percent.

• Engineered solid section shipment volumes increased 22 percent.

• Engineered I-joists shipment volumes increased 34 percent.

• Softwood plywood shipment volumes increased 36 percent and average price realizations increased 20 percent.

• Other products purchased for resale increased 38 percent.

Net contribution to earnings

Net contribution to earnings increased $191 million primarily from:

• a $215 million increase primarily due to higher lumber, OSB and plywood price realizations; and

• a $14 million increase in sales volumes across all products.

These increases were partially offset by:

• a $23 million increase in log cost due to continued strong lumber demand and increasing log prices; and

• a $17 million increase in freight expense due to higher shipment volumes.

Our Outlook for Second Quarter 2013

We anticipate comparable earnings from the Wood Products segment in second quarter. We expect higher sales volume across all product lines, offset by slightly lower average selling prices for lumber and OSB and slightly higher raw material costs.

22

Comparing First Quarter 2013 with First Quarter 2012

Net sales

Net sales were comparable year over year:

• Increased sales volumes of 4 percent for pulp were partially offset by decreased price realizations of $22 per ton – 3 percent as global market conditions remained relatively weak.

• Sales volumes for liquid packaging board increased 8,000 tons – 11 percent, which was largely offset by decreased price realizations of $102 per ton – 9 percent.

Net contribution to earnings

Net contribution to earnings decreased $17 million – 35 percent – primarily due to:

• a $10 million decrease due to lower pulp price realizations and

• an $8 million decrease in liquid packaging board price realizations.

Our Outlook for Second Quarter 2013

We expect significantly higher earnings from the Cellulose Fibers segment in second quarter. We anticipate reduced fiber and energy costs, lower maintenance expense and slightly higher pulp price realizations.

Here is a comparison of key statistics related to our single-family operations for the quarters ended March 31, 2013 and 2012:

SUMMARY OF SINGLE-FAMILY STATISTICS

Average price of homes closed (in thousands)	$	394		$	376		$	18
Single-family gross margin(1)	19.5		%	17.2		%	2.3		%

(1) Single-family gross margin equals revenue less cost of sales and period costs.

Comparing First Quarter 2013 with First Quarter 2012

Net sales

Net sales increased $59 million – 43 percent – primarily due to:

• Single-family housing revenues increased $52 million. Home closings increased 33 percent from 349 in 2012 to 463 in 2013. The average price of homes closed increased 5 percent from $376,000 in 2012 to $394,000 in 2013.

• Revenues from land and lot sales increased $8 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 $8 million primarily due to a $9 million increase in contribution from single-family housing operations. In addition to the higher revenues discussed above, single-family gross margins improved to 19.5 percent in 2013 compared to 17.2 percent in 2012, due to a change 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 closings occur.

24

Our Outlook for Second Quarter 2013

We expect a slight profit from single-family homebuilding in second quarter. Home closings should increase seasonally to approximately 600 single-family homes, with a slightly lower average closing price due to mix. Although input costs are rising, average margins should be comparable to first quarter. We anticipate higher selling-related expenses due to the additional closing volume.

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.

Interest income and other	9			10			(1		)
Net contribution to earnings	$	(46	)	$	16		$	(62	)

Changes in Unallocated Items were primarily due to recognized gains of $52 million during first quarter 2012 related to a previously announced postretirement plan amendment.

INTEREST EXPENSE

Our net interest expense incurred was:

• $82 million during first quarter 2013 and

• $87 million during first quarter 2012.

Interest expense incurred decreased primarily due to lower interest on a lower level 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 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, excluding discrete items, is34.7 percent.

25

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 5	$	(18	)
State income tax settlements	$	8

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 twelve months when tax examinations are expected to be completed.

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 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 used in our operations was:

• $61 million in 2013 and

• $60 million in 2012.

Comparing 2013 with 2012

Net cash used in operations in 2013 was comparable with 2012, primarily due to a $297 million increase in cash received from customers being largely offset by a $292 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 business increased.

Expected Pension Contributions and Benefit Payments

As disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012, in 2013 we expect to:

• make approximately$88 millionof required contributions to our Canadian registered and nonregistered pension plans in 2013;

• make benefit payments of$19 millionto our U.S. nonqualified pension plans; and

• make benefit payments of $37 millionrelated to our U.S. and Canadian other postretirement plans.

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

Real Estate	2		1
Unallocated Items	1		—
Total	$	48	$	64

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

Variable Interest Entities

During second quarter 2013, our cash will be used to pay approximately $162 million for a note related to one of our timber monetization special-purpose entities (SPEs) undertaken in 2003. We will receive approximately $184 million in second quarter 2013 when the related financial investment matures. More information about this entity, which was 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.

CASH FROM FINANCING ACTIVITIES

Consolidated net cash used by financing activities was:

• $156 million in 2013 and

• $108 million in 2012.

Debt

We repaid debt of:

• $156 million in 2013, and

• $2 million in 2012.

Debt maturities in the next twelve months are:

• $21 million in second quarter 2013

• $163 million in third quarter 2013 and

• $69 million in fourth quarter 2013.

There are no maturities in first quarter 2014.

Revolving credit facility

Weyerhaeuser Company and Weyerhaeuser Real Estate Company (WRECO) have a $1.0 billion 4-year revolving credit facility that expires in June 2015. 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.

27

There were no net proceeds from the issuance of debt or from borrowings (repayments) under our available credit facility in first quarter 2013 or 2012.

As of March 31, 2013 Weyerhaeuser Company and WRECO:

• had no borrowings outstanding under the credit facility and

• were in compliance with the credit facility covenants.

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:

• $81 million in 2013 and

• $5 million in 2012.

The increase in exercises of stock options is primarily due to the increase in our average stock price. In first quarter 2013, our average stock price was $30.34, a 46 percent increase, compared to $20.76 during first quarter 2012.

Paying dividends and repurchasing stock

We paid dividends of:

• $93 million in 2013 and

• $81 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.

On April 11, 2013, our board of directors declared a regular dividend of 20 cents per share, a 33 percent increase in our quarterly dividend compared to first quarter 2012, payable May 31, 2013, to shareholders of record at the close of business May 10, 2013.

CRITICAL ACCOUNTING POLICIES

There have been no significant changes during first quarter 2013 to our critical accounting policies presented in our 2012 Annual Report on Form 10-K.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

No changes occurred during first quarter 2013 that had a material effect on the information relating to quantitative and qualitative disclosures about market risk that was provided in the company’s Annual Report on Form 10-K for the year ended December 31, 2012.

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. The reclassifications include where we report the elimination of intersegment profit on inventory and the LIFO reserve. Previously these company-level adjustments were recorded in the business segments and are now recorded in Unallocated Items. This provides a better understanding of business operating results.

SHARE-BASED COMPENSATION

In first quarter 2013, we granted 1,902,816 stock options, 707,305 restricted stock units and 346,107 performance share units. In addition, 442,928 outstanding restricted stock units and 157,386 outstanding performance share units vested during first quarter 2013. A total of 4,180,264 shares of common stock were issued as a result of restricted stock unit vesting, performance share unit vesting and stock option exercises.

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.

STOCK OPTIONS

The weighted average exercise price of all of the stock options granted in 2013 was $30.54. The vesting and post-termination vesting terms for stock options granted in 2013 were as follows:

• options vest ratably over 4 years;

• options vest or continue to vest in the event of disability or death;

• options continue to vest upon retirement at an age of at least 62, but a portion of the grant is forfeited if retirement occurs before the one year anniversary of the grant depending on the employment period after grant date;

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

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

NET EARNINGS PER SHARE

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

• $0.26 during first quarter 2013; and

• $0.08 during first quarter 2012.

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

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

• weighted average number of our outstanding common shares and

• the effect of our outstanding dilutive potential common shares.

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.

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.

Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [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.

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.

This gain is included in other operating income and reflected in the amortization of prior service credit in the table above.

As disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012, the value reported for our pension plan assets at the end of 2012 was estimated.

We expect to complete the valuation of our pension plan assets during second quarter 2013. The final adjustments could affect net pension periodic benefit cost.

• make approximately$88 millionof required contributions to our Canadian registered and nonregistered pension plans in 2013;

• make benefit payments of$19 millionto our U.S. nonqualified pension plans; and

• make benefit payments of $37 millionrelated to our U.S. and Canadian other postretirement plans.

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

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.

ENVIRONMENTAL MATTERS

Our environmental matters include:

• site remediation and

• asset retirement obligations.

Site Remediation

Under the Comprehensive Environmental Response Compensation and Liability Act – commonly known as the Superfund – and similar state laws, we:

• are a party to various proceedings related to the cleanup of hazardous waste sites and

• have been notified that we may be a potentially responsible party related to the cleanup of other hazardous waste sites for which proceedings have not yet been initiated.

As of March 31, 2013, our total accrual for future estimated remediation costs on the active Superfund sites and other sites for which we are responsible was approximately $31 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 March 31, 2013, our total accruals for these obligations was $65 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.

BASIS OF PRESENTATION (Policies)

Mar. 31, 2013

Consolidation, Policy

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.

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, excluding discrete items, is34.7 percent.

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 5	$	(18	)
State income tax settlements	$	8

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 twelve months when tax examinations are expected to be completed.
