RISK FACTORS
We are subject to certain risks and events that, if one or more of them occur, could adversely affect our business, our financial condition and our results of operations and the trading price of our common stock.

You should consider the following risk factors, in addition to the other information presented in this report and the matters described in “Forward-Looking Statements,” as well as the other reports and registration statements we file from time to time with the SEC, in evaluating us, our business, and an investment in our securities.

The risks below are not the only risks we face. Additional risks not currently known to us or that we currently deem immaterial also may adversely affect our business.

RISKS RELATED TO OUR INDUSTRIES AND BUSINESS Cyclical Industries
The industries in which we operate are highly cyclical. Fluctuations in the prices of and the demand for our products could result in smaller profit margins and lower sales volumes.

Our businesses are highly cyclical. Historically, economic and market shifts, fluctuations in capacity and changes in foreign currency exchange rates and mortgage interest rates have created cyclical changes in prices, sales volume and margins for our products. The length and magnitude of industry cycles have varied over time and by product but generally reflect changes in macroeconomic conditions and levels of industry capacity.

Many of our products are commodities that are widely available from other producers. Because commodity products have few distinguishing properties from producer to producer, competition for these products is based primarily on price, which is determined by supply relative to demand.

The overall levels of demand for the products we manufacture and distribute, and consequently our sales and profitability, reflect fluctuations in levels of end-user demand, which depend in part on general macroeconomic conditions in North America and worldwide, and local economic conditions, and competition from substitute products.

Changes in the following are some of the factors that may adversely affect our businesses and the results of operations:

• industrial, nondurable goods production;
• consumer spending;
• employment levels;
• job growth;
• population growth;
• new home construction and repair and remodeling activity;
• consumer confidence;
• interest rates; and
• currency exchange rates.

Industry supply of logs, pulp, paper, packaging and wood products also is subject to fluctuation, as changing industry conditions may cause producers to idle or permanently close individual machines or entire mills or to decrease harvesting levels. In addition, to avoid substantial cash costs in connection with idling or closing a mill, some producers choose to continue to operate at a loss, which could prolong weak prices due to oversupply. Oversupply also may result from producers introducing new capacity or increasing harvest levels in response to favorable short-term pricing trends.

Industry supply of pulp, paper and containerboard also are influenced by overseas production capacity, which has grown in recent years and is expected to continue to grow. While the weakness of the U.S. dollar has mitigated the levels of imports in recent years, imports of pulp, paper and containerboard from overseas may increase, resulting in lower prices.

Prices for our products are affected by many factors outside of our control, and we will have little influence over the timing and extent of price changes, which often are volatile. Because market conditions beyond our control determine the prices for our commodity products, the price for any one or more of these products may fall below our cash production costs, requiring us either to incur cash losses on product sales or cease production at one or more of our manufacturing facilities or curtail harvest levels. Our profitability with respect to these products depends on managing our costs, particularly raw material and energy costs, which represent significant components of our operating costs and can fluctuate based upon factors beyond our control, as described below. If the prices of or demand for our products declines, if our raw material or energy costs increase, or both, our sales and profitability could be materially and adversely affected.

Substitution
Some of our products are vulnerable to declines in demand due to competing technologies or materials.

Our products may compete with nonfiber-based alternatives or with alternative products in certain market segments. For example, plastic packaging may be used as an alternative to our corrugated packaging business products; and plastic, wood/plastic or composite materials may be used by builders as alternatives to the products produced by our wood products businesses such as lumber, veneer, plywood and oriented strand. Changes in prices for oil, chemicals and wood-based fiber can change the competitive position of our products relative to available alternatives and could increase substitution of those products for our products. As the use of these alternatives grows, demand for our products may further decline.

Changes in Product Mix or Pricing
Our results of operation and financial condition could be materially adversely affected by changes in product mix or pricing.

Our results may be affected by a change in our sales mix. Our outlook assumes a certain volume and product mix of sales. If actual results vary from this projected volume and product mix of sales, our operations and our results could be negatively affected. Our outlook also assumes we will be successful in implementing previously announced price increases as well as future price increases. Delays in acceptance of price increases could negatively affect our results. Moreover, price discounting, if required to maintain our competitive position, could result in lower than anticipated price realizations.

Intense Competition
We face intense competition in our markets, and the failure to compete effectively could have a material adverse effect on our business, financial condition and results of operations.

We compete with North American and, for many of our product lines, global producers, some of which may have greater financial resources and lower production costs than we do. The principal basis for competition is selling price. Our ability to maintain satisfactory margins depends in large part on our ability to control our costs. Our industries are also particularly sensitive to other factors including innovation, design, quality and service, with varying emphasis on these factors depending on the product line. To the extent that one or more of our competitors become more successful with respect to any key competitive factor, our ability to attract and retain customers could be materially adversely affected. We cannot assure you that we will be able to compete effectively and maintain current levels of sales and profitability. If we are unable to compete effectively, such failure could have a material adverse effect on our business, financial condition and results of operations.

Availability of Raw Materials and Energy
Our business and operations could be materially adversely affected by changes in the cost or availability of raw materials and energy.

We rely heavily on certain raw materials (principally wood fiber and chemicals) and energy sources (principally natural gas, electricity, coal and fuel oil) in our manufacturing processes. Our ability to increase earnings has been, and will continue to be, affected by changes in the costs and availability of such raw materials and energy sources. We may not be able to fully offset the effects of higher raw material or energy costs through hedging arrangements, price increases, productivity improvements, or cost-reduction programs.

Transportation
We depend on third parties for transportation services and increases in costs and the availability of transportation could materially adversely affect our business and operations.

Our business depends on the transportation of a large number of products, both domestically and internationally. We rely primarily on third parties for transportation of the products we manufacture and/or distribute as well as delivery of our raw materials. In particular, a significant portion of the goods we manufacture and raw materials we use are transported by railroad or trucks, which are highly regulated.

If any of our third-party transportation providers were to fail to deliver the goods we manufacture or distribute in a timely manner, we may be unable to sell those products at full value—or at all. Similarly, if any of these providers were to fail to deliver raw materials to us in a timely manner, we may be unable to manufacture our products in response to customer demand. In addition, if any of these third parties were to cease operations or cease doing business with us, we may be unable to replace them at reasonable cost.

Any failure of a third-party transportation provider to deliver raw materials or finished products in a timely manner could harm our reputation, negatively affect our customer relationships and have a material adverse effect on our financial condition and results of operation.

In addition, an increase in transportation rates or fuel surcharges could materially adversely affect our sales and profitability.

Material Disruption of Manufacturing
A material disruption at one of our manufacturing facilities could prevent us from meeting customer demand, reduce our sales or negatively affect our results of operation and financial condition.

Any of our manufacturing facilities, or any of our machines within an otherwise operational facility, could cease operations unexpectedly due to a number of events, including:

• unscheduled maintenance outages;
• prolonged power failures;
• an equipment failure;
• a chemical spill or release;
• explosion of a boiler;
• the effect of a drought or reduced rainfall on its water supply;
• labor difficulties;
• disruptions in the transportation infrastructure, including roads, bridges, railroad tracks and tunnels;
• fires, floods, windstorms, earthquakes, hurricanes or other catastrophes;
• terrorism or threats of terrorism;
• governmental regulations; and
• other operational problems.

Any such downtime or facility damage could prevent us from meeting customer demand for our products and/or require us to make unplanned capital expenditures. If one of these machines or facilities were to incur significant downtime, our ability to meet our production targets and satisfy customer requirements could be impaired, resulting in lower sales and income.

Capital Requirements
Our operations require substantial capital.

Capital expenditures for expansion or replacement of existing facilities or equipment may be substantial. Although we maintain our production equipment with regular periodic and scheduled maintenance, we cannot assure you that key pieces of equipment in our various production processes will not need to be repaired or replaced and major equipment may need to be replaced periodically. The costs of repairing or replacing such equipment and the associated downtime of the affected production line could have a material adverse effect on our financial condition, results of operations and cash flows.

Based on our current operations, we believe our cash flow from operations and other capital resources will be adequate to meet our operating needs, capital expenditures and other cash requirements for the foreseeable future. If for any reason we are unable to provide for our operating needs, capital expenditures and other cash requirements on economic terms, we could experience a material adverse effect on our business, financial condition, results of operations and cash flows.

Environmental Laws and Regulations
We could incur substantial costs as a result of compliance with, violations of or liabilities under applicable environmental laws and regulations.

We are subject to a wide range of general and industry-specific laws and regulations relating to the protection of the environment, including those governing:

• air emissions;
• wastewater discharges;
• harvesting;
• silvicultural activities;
• the storage, management and disposal of hazardous substances and wastes;
• the cleanup of contaminated sites;
• landfill operation and closure obligations;
• forestry operations and endangered species habitat; and
• health and safety matters.

In particular, the pulp and paper industry in the U.S. is subject to Cluster Rules and Boiler Maximum Achievable Control Technology Rules that further regulate effluent and air emissions. These laws and regulations will require us to obtain authorizations from and comply with the authorization requirements of the appropriate governmental authorities, which have considerable discretion over the terms and timing of permits.

We have incurred, and we expect to continue to incur, significant capital, operating and other expenditures complying with applicable environmental laws and regulations and as a result of remedial obligations. We also could incur substantial costs, such as civil or criminal fines, sanctions and enforcement actions (including orders limiting our operations or requiring corrective measures, installation of pollution control equipment or other remedial actions), cleanup and closure costs, and third-party claims for property damage and personal injury as a result of violations of, or liabilities under, environmental laws and regulations.

As the owner and operator of real estate, we may be liable under environmental laws for cleanup, closure and other damages resulting from the presence and release of hazardous substances on or from our properties or operations. The amount and timing of environmental expenditures is difficult to predict, and in some cases, our liability may exceed forecasted amounts or the value of the property itself. The discovery of additional contamination or the imposition of additional cleanup obligations at our sites or third-party sites may result in significant additional costs. Any material liability we incur could adversely affect our financial condition or preclude us from making capital expenditures that otherwise would benefit our business.

Enactment of new environmental laws or regulations or changes in existing laws or regulations, or the interpretation of these laws or regulations, might require significant expenditures.

Legal Proceedings
We are a party to a number of legal proceedings, and adverse judgments in certain legal proceedings could have a material adverse effect on our financial condition.

The costs and other effects of pending litigation against us and related insurance recoveries cannot be determined with certainty. Although the disclosure in “Legal Proceedings” and Note 16 of “Notes to Consolidated Financial Statements” contains management’s current views, when possible, of the effect such litigation will have on our financial results, there can be no assurance that the outcome of such proceedings will be as expected.

For example, in 1999, the Equity Committee in the Paragon Trade Brands Inc. bankruptcy proceeding sued us for breach of warranties in agreements between us and Paragon relating to Paragon’s initial public stock offering. The bankruptcy court held us liable for breaches of warranty and imposed damages of approximately $470 million. The U.S. District Court overturned the decision and directed the Bankruptcy Court to enter judgment in favor of the Company, but the litigation claims representative has appealed the decision to the 11th Circuit Court of Appeals. We believe that we will prevail on the appeal and we have not established a reserve for this litigation because we believe that the requirements for establishing a reserve under Statement of Financial Accounting Standards No. 5, [Accounting for Contingencies] (Statement 5) have not been met. However, it is possible in the future that there could be a charge for all or a portion of any damage award.

There also have been several lawsuits filed against us alleging that we violated U.S. antitrust laws. Several lawsuits have been filed since 2000 in U.S. District Court in Oregon alleging we had monopoly power or attempted to gain monopoly power for alder logs and finished alder lumber in the Pacific Northwest market (the Alder Cases). In 2006, a series of lawsuits against us and other manufacturers of oriented strand board (OSB) were consolidated into one case in the U.S. District Court in Pennsylvania on behalf of purchasers of OSB. The lawsuit alleges that the manufacturers conspired to fix and raise OSB prices and caused the purchasers of OSB to pay artificially inflated prices. In the event liability is found in an antitrust case, the damages proved at trial are trebled. Jury verdicts and damages imposed against us in two of the Alder Cases were vacated as a result of a ruling by the U.S. Supreme Court in our favor in one of the Alder Cases and we have settled three of these cases, but one case is still pending. In the OSB case, the U.S. District Court has issued a number of rulings approving class action status for various classes of direct and indirect purchasers for the period June 2002 through February 2006. We have not established a reserve for any of these cases and intend to contest these cases vigorously. We are not able to estimate the amount of charges, if any, that may be required in the future.

It is possible that there could be adverse judgments against us in some or all of these cases and that we could be required to take a charge for all or a portion of any damage award. Any such charge could materially and adversely affect our results of operations for the quarter or year in which we record it.

Currency Exchange Rates
We will be affected by changes in currency exchange rates.

We have manufacturing operations in Canada, Mexico, Australia, Uruguay and Brazil, and we are also a large exporter and, as a result, are affected by changes in currency exchange rates, particularly the value of the U.S. dollar relative to the euro and the Canadian dollar.

Export Taxes
We may be required to pay significant export taxes or countervailing and anti-dumping duties for exported products.

We may experience reduced revenues and margins on some of our businesses as a result of export taxes or countervailing and anti-dumping duty applications. For example, in 2001, a group of companies filed petitions with the U.S. Department of Commerce and the International Trade Commission claiming that production of softwood lumber in Canada was being subsidized by Canada and that imports into the U.S. from Canada were being sold in U.S. markets at less than their fair value. We have softwood lumber facilities in Canada that export lumber into the U.S. We paid a total of $370 million in deposits for countervailing duty and anti-dumping tariffs from 2002 through 2006 related to those lumber exports. The U.S. and Canadian governments reached a settlement of the dispute in 2006. As a result of the settlement, we received a refund of $344 million in the fourth quarter of 2006. However, our Canadian softwood lumber facilities will have to pay an export tax when the price of lumber is at or below a threshold price. The export tax could be as high as 22.5 percent if a province exceeds its total allotted export share. Similar types of actions have been initiated from time to time against us and other U.S. producers of products such as paper, corrugated containerboard sheets or lumber by countries such as China, Korea and Mexico. It is possible that countervailing duty and antidumping tariffs, or similar types of tariffs could be imposed on us in the future. We may experience reduced revenues and margins in any business that is subject to such tariffs or to the terms of the settlements of such international disputes. These tariffs or settlement terms could have a material adverse effect on our business, financial results and financial condition, including facility closures or impairments of assets.

Changes in Credit Ratings
Changes in credit ratings issued by nationally recognized statistical rating organizations could adversely affect our cost of financing and have an adverse effect on the market price of our securities.

Credit rating agencies rate our debt securities on factors that include our operating results, actions that we take, their view of the general outlook for our industry, and their view of the general outlook for the economy. Actions taken by the rating agencies can include maintaining, upgrading or downgrading the current rating, or placing the company on a watch list for possible future downgrading. Downgrading the credit rating of our debt securities or placing us on a watch list for possible future downgrading would likely increase our cost of financing and have an adverse effect on the market price of our securities.

Natural Disasters
Our business and operations could be adversely affected by weather, fire, infestation or natural disasters.

Our timberlands assets may be damaged by adverse weather, fires, pest infestation or other natural disasters. Because our manufacturing processes primarily use wood fiber, in many cases from our own timberlands, in the event of material damage to our timberlands, our operations could be disrupted or our production costs could be increased.

RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK Stock Price Volatility
The price of our common stock may be volatile.

The market price of our common stock may be influenced by many factors, some of which are beyond our control, including those described above under “Risks Related to our Industries and Business” and the following:

• actual or anticipated fluctuations in our operating results or our competitors’ operating results;
• announcements by us or our competitors of new products, capacity changes, significant contracts, acquisitions or strategic investments;
• our growth rate and our competitors’ growth rates;
• the financial market and general economic conditions;
• changes in stock market analyst recommendations regarding us, our competitors or the forest products industry generally, or lack of analyst coverage of our common stock;
• sales of our common stock by our executive officers, directors and significant stockholders or sales of substantial amounts of common stock; and
• changes in accounting principles.

In addition, there has been significant volatility in the market price and trading volume of securities of companies operating in the forest products industry that often has been unrelated to the operating performance of particular companies.

Some companies that have had volatile market prices for their securities have had securities litigation brought against them. If litigation of this type is brought against us, it could result in substantial costs and would divert management’s attention and resources.

RISKS RELATED TO THE DOMTAR TRANSACTION
On March 7, 2007, we completed a transaction combining our fine paper business and related assets with Domtar Inc., a Canadian corporation, to form a new company, Domtar Corporation (Domtar). The transaction was structured in a manner that was tax-free to us and our shareholders. In connection with the transaction, we entered into a tax-sharing agreement with Domtar that requires Domtar, its subsidiaries and its affiliates, for a two-year period following closing of the transaction to avoid taking certain actions that might adversely affect the tax-free status of the transaction. To the extent that the tax-free status of the transaction is lost because of actions taken by Domtar, Domtar is generally required to indemnify us for any resulting tax-related losses incurred by us or our shareholders. In the event that conduct by Domtar affects the tax-free status of the transaction and Domtar is unable to meet its obligation to indemnify us and our shareholders, Weyerhaeuser and its shareholders could incur significant tax obligations.
