NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

FOR THE QUARTERS ENDED MARCH 31, 2014 AND 2013

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.

Throughout these Notes to Consolidated Financial Statements, unless specified otherwise, references to “Weyerhaeuser,” “we” and “our” refer to the consolidated company.

The accompanying unaudited Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. Except as otherwise disclosed in these Notes to Consolidated Financial Statements, such adjustments are of a normal, recurring nature. The Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission pertaining to interim financial statements; certain disclosures normally provided in accordance with accounting principles generally accepted in the United States have been omitted. These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2013. 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 2014 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. Additionally, our real estate and forest products asset and liability line items have been combined into our respective total asset and liability line items on our Consolidated Balance Sheetand in the related footnotes.

NEW ACCOUNTING PRONOUNCEMENTS

In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update 2013-11, which provides guidance on the presentation of unrecognized tax benefits, reflecting the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses or tax credit carryforwards exist. Our prospective adoption of this guidance in first quarter 2014 did not have a material effect on our results of operations, financial position or cash flows.

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 was a privately-held Delaware limited liability company engaged in the ownership and management of approximately 645,000 acres of timberlands 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 2013, is as follows:

	QUARTER ENDED
DOLLAR AMOUNTS IN MILLIONS, EXCEPT PER-SHARE FIGURES	MARCH 2013
Net sales	$	2,003
Net earnings attributable to Weyerhaeuser common shareholders	$	150
Earnings per share attributable to Weyerhaeuser common shareholders, basic and diluted	$	0.26

NOTE 3:REAL ESTATE DIVESTITURE

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 expect the transaction to close early in third quarter 2014.

NOTE 4: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:

Net earnings	194			144
Dividends on preference shares	(11		)	—
Net earnings attributable to Weyerhaeuser common shareholders	$	183		$	144

(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 outstanding borrowings and the elimination of intersegment profit in inventory and the LIFO reserve.

NOTE 5:NET EARNINGS PER SHARE

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

• $0.31 during first quarter 2014; and

• $0.26 during first quarter 2013.

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.

7

Diluted earnings per share is net earnings available to common shareholders divided by the sum of the:

• weighted average number of our outstanding common shares and

• the effect of our outstanding dilutive potential common shares.

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 ended March 31, 2014. 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.

NOTE 6:INVENTORIES

Inventories include raw materials, work-in-process and finished goods.

DOLLAR AMOUNTS IN MILLIONS	MARCH 31, 2014		DECEMBER 31, 2013
LIFO Inventories:
Logs and chips	$	18	$	15
Lumber, plywood and panels	69		46
Pulp and paperboard	103		97
Other products	13		11
FIFO or moving average cost inventories:
Logs and chips	59		33
Lumber, plywood, panels and engineered lumber	89		70
Pulp and paperboard	34		30
Other products	92		94
Materials and supplies	149		146
Total	$	626	$	542

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 $119 million and $112 million higher as of March 31, 2014 and December 31, 2013, respectively.

NOTE 7:PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

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

During fourth quarter 2013, we decided to eliminate post-Medicare health funding for certain salaried retirees after 2014. As a result, we will ratably amortize a total pretax gain of $177 million throughout 2014. We recognized a pretax gain of $45 million in first quarter 2014 from this plan amendment. This gain is included in "Other operating income, net" in our Consolidated Statement of Operations 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, 2013, the value reported for our pension plan assets at the end of 2013 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 2014. 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, 2013, in 2014 we expect to:

• make approximately$53 millionof required contributions to our Canadian registered pension plan;

• make$3 millionof required contributions or benefit payments to our Canadian nonregistered pension plans;

• make benefit payments of$20 millionfor our U.S. nonqualified pension plans; and

• make benefit payments of $35 million for our U.S. and Canadian other postretirement plans.

We donotanticipate making a contribution to our U.S. qualified pension plan for 2014.

NOTE 8:ACCRUED LIABILITIES

Accrued liabilities were comprised of the following:

DOLLAR AMOUNTS IN MILLIONS	MARCH 31, 2014		DECEMBER 31, 2013
Wages, salaries and severance pay	$	145	$	174
Pension and postretirement	56		57

Deferred income	80		98
Estimated cost for real estate development completion	33		48
Other	133		119
Total	$	661	$	742

NOTE 9:FAIR VALUE OF FINANCIAL INSTRUMENTS

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

	MARCH 31, 2014				DECEMBER 31, 2013
DOLLAR AMOUNTS IN MILLIONS	CARRYING  VALUE		FAIR VALUE (LEVEL 2)		CARRYING  VALUE		FAIR VALUE (LEVEL 2)
Long-term debt (including current maturities)	$	4,891	$	5,856	$	4,891	$	5,683

10

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

• market approach – based on quoted market prices we received for the same types and issues of our debt; or

• income approach – based on the discounted value of the future cash flows using market yields for the same type and comparable issues of debt.

The inputs to these valuations are based on market data obtained from independent sources or information derived principally from observable market data.

The difference between the fair value and the carrying value represents the theoretical net premium or discount we would pay or receive to retire all debt at the measurement date.

FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS

We believe that our other financial instruments, including cash and cash equivalents, short-term investments, 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 10:LEGAL PROCEEDINGS, COMMITMENTS AND CONTINGENCIES

This note provides details about our:

• legal proceedings and

• environmental matters.

LEGAL PROCEEDINGS

We are party to various legal proceedings arising in the ordinary course of business, however, we are not currently a party to any legal proceeding that management believes could have a material adverse effect on our long-term financial position, results of operations or cash flows.

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, 2014, 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 2013.

11

Asset Retirement Obligations

We have obligations associated with the retirement of tangible long-lived assets consisting primarily of reforestation obligations related to forest management licenses in Canada and obligations to close and cap landfills. As of March 31, 2014, our total accruals for these obligations was $45 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 2013.

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 14:OTHER OPERATING INCOME, NET

Other operating income, net:

• includes both recurring and occasional income and expense items and

• can fluctuate from year to year.

Items Included in Other Operating Income, Net

	QUARTER ENDED

Gain on disposition of non-strategic assets in 2014 included a $22 million pretax gain recognized in first quarter 2014 on the sale of a landfill in Washington State.

Foreign exchange losses result from changes in exchange rates on transactions, primarily related to our Canadian operations.

Land management income includes income from recreational activities, land permits, grazing rights, firewood sales and other miscellaneous income related to land management activities.

NOTE 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 2014 provision for income taxes is based on the current estimate of the annual effective tax rate. Our 2014 estimated annual effective tax rate for our TRS is approximately34 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.

There were no significant discrete items excluded from the calculation of our effective income tax rate for 2014 or 2013.

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 ended March 31, 2014, compared to the quarter ended March 31, 2013.

CONSOLIDATED RESULTS

How We Did in First Quarter 2014

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, 2014 and 2013:

	QUARTER ENDED				AMOUNT OF CHANGE
DOLLAR AMOUNTS IN MILLIONS, EXCEPT PER-SHARE FIGURES	MARCH 2014		MARCH 2013		2014 VS. 2013
Net sales	$	1,984	$	1,951	$	33
Operating income	$	324	$	256	$	68
Net earnings attributable to Weyerhaeuser common shareholders	$	183	$	144	$	39
Net earnings per share attributable to Weyerhaeuser common shareholders, basic and diluted	$	0.31	$	0.26	$	0.05

Comparing First Quarter 2014 with First Quarter 2013

Net sales

Net sales increased $33 million – 2 percent – primarily due to the following:

• Timberlands segment sales increased $84 million, primarily due to higher export and domestic log prices and increased sales volume in the West and from the purchase of Longview Timber.

• Real Estate segment sales increased $52 million, primarily due to increased home closings and improved average prices for homes closed.

These increases were partially offset by:

• a $90 million decrease in our Wood Products segment sales, primarily due to lower sales realizations and lower shipment volumes for structural lumber and oriented strand board (OSB); and

• a $13 million decrease in our Cellulose Fibers segment sales, primarily due to lower sales volumes for pulp and liquid packaging board.

18

Net earnings attributable to Weyerhaeuser common shareholders

Our net earnings attributable to Weyerhaeuser common shareholders increased $39 million – 27 percent – primarily due to the following:

• a $99 million increase in gross margin in our Timberlands, Cellulose Fibers and Real Estate segments. Our Timberlands and Cellulose Fibers segment increases were primarily due to higher sales realizations and the purchase of Longview Timber. Increased gross margin in our Real Estate segment was primarily due to increased single-family home closings and improved average prices for homes closed.

• a $56 million increase in other operating income, primarily due to a $45 million pretax gain recognized in 2014 related to a previously announced postretirement plan amendment.

These increases were partially offset by a $110 million decrease in gross margin in our Wood Products segment, primarily due to lower sales realizations in OSB and lumber.

TIMBERLANDS

How We Did First Quarter 2014

Here is a comparison of net sales to unaffiliated customers, intersegment sales, and net contribution to earnings for the quarters ended March 31, 2014 and 2013:

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 forward 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 First Quarter 2014 with First Quarter 2013

Net sales – unaffiliated customers

Net sales to unaffiliated customers increased $84 million – 29 percent – driven by an $80 million increase in Western log sales due to higher export and domestic log prices and a 34 percent increase in sales volume as a result of increased export demand and from the purchase of Longview Timber.

Intersegment sales

Intersegment sales increased $14 million – 6 percent – primarily from a $16 million increase due to higher log prices in our legacy Western and Southern timberlands.

Net contribution to earnings

Net contribution to earnings increased $60 million – 58 percent – primarily from:

• a $38 million increase due to the purchase of Longview Timber,

• a $37 million increase due to higher log prices in our legacy Western timberlands and the South; and

• a $7 million increase due to higher sales volumes and demand for export logs in our legacy Western timberlands.

The above items were partially offset by a $24 million increase in operating costs in our legacy Western timberlands primarily due to increased harvest levels and outside purchased logs.

• Structural lumber shipment volumes decreased 4 percent and average sales realizations decreased 2 percent.

• OSB shipment volumes decreased 2 percent and average sales realizations decreased 36 percent.

These items were partially offset by an increase of 21 percent of complementary products purchased for resale.

Net contribution to earnings

Net contribution to earnings decreased $114 million – 64 percent – primarily from:

• an $86 million decrease, primarily due to lower sales realizations in OSB and lumber;

• a $16 million increase in log cost due to increasing log prices; and

• a $9 million increase in manufacturing costs due to adverse weather and startup of our Evergreen, Alabama engineered lumber facility.

Comparing First Quarter 2014 with First Quarter 2013

Net sales

Net sales decreased $13 million – 3 percent – primarily due to:

• Decreased sales volumes of 6 percent for pulp related to timing of shipments, which was partially offset by increased sales realizations of $29 per ton – 4 percent.

• Decreased sales volumes of 9 percent for liquid packaging board, which was partially offset by increased sales realizations of $43 per ton – 4 percent.

Net contribution to earnings

Net contribution to earnings increased $23 million – 74 percent – primarily due to:

• a $13 million increase in pulp sales realizations; and

• a $13 million decrease in maintenance and freight costs, Canadian operating costs due to the strengthening U.S. dollar and higher productivity.

These increases were partially offset by a $6 million increase in energy costs.

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

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, Weyerhaeuser Real Estate Company (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 our 2013 Annual Report on Form 10-K.

Comparing First Quarter 2014 with First Quarter 2013

Net sales

Net sales increased $52 million – 27 percent – primarily due to:

• Single-family housing revenues increased $59 million. Home closing increased 10 percent from 463 in 2013 to 508 in 2014. The average price of homes closed increased 21 percent from $394,000 in 2013 to $476,000 in 2014, with year-over-year increases in each of our markets.

• Revenues from land and lot sales decreased $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.

24

Net contribution to earnings

Net contribution to earnings increased $12 million, primarily due to a $16 million increase in earnings from single-family home sales. In addition to higher closing volumes and higher average prices, single-family gross margin increased from 19.5 percent in 2013 to 20.9 percent in 2014.

This was partially offset by a $3 million increase in selling expenses, primarily due to volume related increases in selling costs and additional costs associated with an increased number of open communities.

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 outstanding borrowings and the elimination of intersegment profit in inventory and the LIFO reserve.

Net contribution to earnings	$	39		$	(46	)	$	85

Changes in Unallocated Items were primarily related to:

• a $45 million pretax gain recognized in first quarter 2014 related to a previously announced postretirement plan amendment;

• a $22 million pretax gain recognized in first quarter 2014 on the sale of a landfill in Washington State, which is recorded in "Other operating income, net" in our Consolidated Statement of Operations; and

• $18 million in charges recognized in first quarter 2014 related to our selling, general and administrative cost reduction initiative.

INTEREST EXPENSE

Our net interest expense incurred was:

• $83 million during first quarter 2014 and

• $82 million during first quarter 2013.

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.

25

The 2014 provision for income taxes is based on the current estimate of the annual effective tax rate. Our 2014 estimated annual effective tax rate for our TRS is approximately34 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.

There were no significant discrete items excluded from the calculation of our effective income tax rate for 2014 or 2013.

LIQUIDITY AND CAPITAL RESOURCES

We are committed to maintaining an appropriate capital structure that enables us to:

• protect the interests of our shareholders and lenders,

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

• minimize liquidity risk by managing timing of debt maturities.

CASH FROM OPERATIONS

Consolidated net cash provided (used) by our operations was:

• $109 million in 2014 and

• $(61) million in 2013.

Comparing 2014 with 2013

Net cash from operations increased $170 million in 2014 as compared with 2013, primarily due to:

• a $197 million increase in cash received from customers as sales increased in our Timberlands and Real Estate segments and

• a $48 million increase in cash received from tax refunds.

These increases were partially offset by an $87 million increase in cash paid to employees and suppliers as sales and production increased in our Timberlands and Real Estate segments.

Expected Pension Contributions and Benefit Payments

As disclosed in our Annual Report on Form 10-K for the year ended December 31, 2013, in 2014 we expect to:

• make approximately$53 millionof required contributions to our Canadian registered pension plan;

• make$3 millionof required contributions or benefit payments to our Canadian nonregistered pension plans;

• make benefit payments of$20 millionfor our U.S. nonqualified pension plans; and

• make benefit payments of $35 million for our U.S. and Canadian other postretirement plans.

We donotanticipate making a contribution to our U.S. qualified pension plan for 2014.

CASH FROM INVESTING ACTIVITIES

Consolidated net cash used by investing activities was:

• $46 million in 2014 and

• $42 million in 2013.

Wood Products	18		10
Cellulose Fibers	26		17
Real Estate	2		2
Unallocated Items	—		1
Total	$	65	$	48

We anticipate that our net capital expenditures for 2014 – excluding acquisitions – to approximate $400 million.

CASH FROM FINANCING ACTIVITIES

Consolidated net cash used by financing activities was:

• $118 million in 2014 and

• $156 million in 2013.

Debt

There were no payments of debt in 2014. We repaid debt of $156 million in 2013. There are no debt maturities in the next 12 months.

Revolving credit facility

Weyerhaeuser Company and Weyerhaeuser Real Estate Company (WRECO) have a $1 billion 5-year senior unsecured revolving credit facility that expires in September 2018. WRECO can borrow up to $50 million under this facility. Neither of the entities is a guarantor of the borrowing of the other.

There were no net proceeds from the issuance of debt or from borrowings (repayments) under our available credit facility in first quarter 2014 or 2013.

Debt Covenants

As of March 31, 2014 Weyerhaeuser Company and WRECO were in compliance with all debt covenants. There have been no significant changes during first quarter 2014 to our debt covenants presented in our 2013 Annual Report on Form 10-K.

Option Exercises

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

• $15 million in 2014 and

• $81 million in 2013.

The decrease in cash proceeds from the exercise of stock options is primarily due to unusually high stock option exercises in first quarter 2013, 50 percent of total 2013 proceeds. This was primarily caused by our average stock price being 46 percent higher in first quarter 2013 than the prior period. Exercises returned to normal levels by first quarter 2014 due to less volatility in stock price. In first quarter 2014, our average stock price was $30.09, a 1 percent decrease, compared to $30.34 in first quarter 2013.

Paying dividends and repurchasing stock

Dividends per common share declared and paid are as follows:

	QUARTER ENDED
DOLLAR AMOUNTS IN MILLIONS, EXCEPT PER-SHARE FIGURES	MARCH 2014		MARCH 2013
Dividends per common share - declared and paid	$	0.22	$	0.17
Dividends on common shares - amount paid	$	129	$	93

The increase in dividends paid is primarily due to the increase in our quarterly dividend from 17 cents per share to 20 cents per share in April 2013 and to 22 cents per share in August 2013, a 29 percent increase in our quarterly dividend.

On April 10, 2014, our Board of Directors declared a dividend of 22 cents per share on our common stock payable on May 30, 2014 to shareholders of record at the close of business May 9, 2014. 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 July 1, 2014, to shareholders of record at the close of business June 15, 2014.

CRITICAL ACCOUNTING POLICIES

There have been no significant changes during first quarter 2014 to our critical accounting policies presented in our 2013 Annual Report on Form 10-K.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

No changes occurred during first quarter 2014 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, 2013.

NET EARNINGS PER SHARE (Policies)

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 ended March 31, 2014. 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.

Throughout these Notes to Consolidated Financial Statements, unless specified otherwise, references to “Weyerhaeuser,” “we” and “our” refer to the consolidated company.

The accompanying unaudited Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. Except as otherwise disclosed in these Notes to Consolidated Financial Statements, such adjustments are of a normal, recurring nature. The Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission pertaining to interim financial statements; certain disclosures normally provided in accordance with accounting principles generally accepted in the United States have been omitted. These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2013. 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 2014 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. Additionally, our real estate and forest products asset and liability line items have been combined into our respective total asset and liability line items on our Consolidated Balance Sheetand in the related footnotes.

NEW ACCOUNTING PRONOUNCEMENTS

In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update 2013-11, which provides guidance on the presentation of unrecognized tax benefits, reflecting the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses or tax credit carryforwards exist. Our prospective adoption of this guidance in first quarter 2014 did not have a material effect on our results of operations, financial position or cash flows.

FAIR VALUE OF FINANCIAL INSTRUMENTS

FAIR VALUE OF FINANCIAL INSTRUMENTS

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

	MARCH 31, 2014				DECEMBER 31, 2013
DOLLAR AMOUNTS IN MILLIONS	CARRYING  VALUE		FAIR VALUE (LEVEL 2)		CARRYING  VALUE		FAIR VALUE (LEVEL 2)
Long-term debt (including current maturities)	$	4,891	$	5,856	$	4,891	$	5,683

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

• market approach – based on quoted market prices we received for the same types and issues of our debt; or

• income approach – based on the discounted value of the future cash flows using market yields for the same type and comparable issues of debt.

The inputs to these valuations are based on market data obtained from independent sources or information derived principally from observable market data.

The difference between the fair value and the carrying value represents the theoretical net premium or discount we would pay or receive to retire all debt at the measurement date.

FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS

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

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 various legal proceedings arising in the ordinary course of business, however, we are not currently a party to any legal proceeding that management believes could have a material adverse effect on our long-term financial position, results of operations or cash flows.

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, 2014, 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 2013.

Asset Retirement Obligations

We have obligations associated with the retirement of tangible long-lived assets consisting primarily of reforestation obligations related to forest management licenses in Canada and obligations to close and cap landfills. As of March 31, 2014, our total accruals for these obligations was $45 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 2013.

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.

REAL ESTATE DIVESTITURE

REAL ESTATE DIVESTITURE

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 expect the transaction to close early in third quarter 2014.

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 2014 provision for income taxes is based on the current estimate of the annual effective tax rate. Our 2014 estimated annual effective tax rate for our TRS is approximately34 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.

There were no significant discrete items excluded from the calculation of our effective income tax rate for 2014 or 2013.

During fourth quarter 2013, we decided to eliminate post-Medicare health funding for certain salaried retirees after 2014. As a result, we will ratably amortize a total pretax gain of $177 million throughout 2014. We recognized a pretax gain of $45 million in first quarter 2014 from this plan amendment. This gain is included in "Other operating income, net" in our Consolidated Statement of Operations 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, 2013, the value reported for our pension plan assets at the end of 2013 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 2014. 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, 2013, in 2014 we expect to:

• make approximately$53 millionof required contributions to our Canadian registered pension plan;

• make$3 millionof required contributions or benefit payments to our Canadian nonregistered pension plans;

• make benefit payments of$20 millionfor our U.S. nonqualified pension plans; and

• make benefit payments of $35 million for our U.S. and Canadian other postretirement plans.

We donotanticipate making a contribution to our U.S. qualified pension plan for 2014.

NET EARNINGS PER SHARE

NET EARNINGS PER SHARE

NET EARNINGS PER SHARE

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

• $0.31 during first quarter 2014; and

• $0.26 during first quarter 2013.

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

Diluted earnings per share is net earnings available to common shareholders divided by the sum of the:

• weighted average number of our outstanding common shares and

• the effect of our outstanding dilutive potential common shares.

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 ended March 31, 2014. 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.

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 $119 million and $112 million higher as of March 31, 2014 and December 31, 2013, respectively.

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 was a privately-held Delaware limited liability company engaged in the ownership and management of approximately 645,000 acres of timberlands 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.
