Overview

2008 OPERATING PERFORMANCE COMPARED TO 2007

Operating income decreased by $96 million to $328 million in 2008. Our results reflect the weakness in U.S. residential construction markets, which has continued to weaken over the past several years. Sawlog demand from lumber and plywood mills continued to decline in 2008 resulting in lower operating income for both of our Resources Segments during 2008. Operating income in our Northern Resources Segment decreased by $17 million to $41 million in 2008 due primarily to lower sawlog prices and higher per ton log and haul rates. Operating income in our Southern Resources Segment decreased by $33 million to $128 million due primarily to a combination of lower sawlog prices, a weaker sales mix and higher per ton log and haul rates.

Operating losses from our Manufactured Products Segment were $44 million in 2008 compared to essentially break-even operating results in 2007. In addition to lower lumber and plywood prices, operating income was also negatively impacted by inventory and purchase commitment write-downs, lumber manufacturing asset impairment charges and higher MDF raw material costs.

Operating income from our Real Estate Segment decreased by $5 million to $245 million. Despite lower average prices from higher and better use/recreational and small non-strategic land sales and lower sales from development

28 | PLUM CREEK 2008 FORM 10-K

properties, operating income was similar to 2007 due primarily to a large multi-period conservation sales contract in Montana, which contributed $74 million to operating income in 2008.

On October 1, 2008, to capture strong timberland values, we contributed 454,000 acres of timberlands to Southern Diversified Timber, LLC ("the Timberland Venture") in exchange for a $705 million preferred interest and a 9% common interest valued at $78 million. The Timberland Venture's other member contributed $783 million of cash in exchange for a common interest. Following the contribution, we borrowed $783 million from the Timberland Venture. As a result of the Timberland Venture, we reported equity earnings of $15 million, primarily related to our preferred interest, and $14 million of interest expense associated with the $783 million indebtedness. See Note 3 of the Consolidated Notes to Financial Statements.

Our 2008 earnings were positively impacted by lower interest expense on our debt obligations (excluding interest expense from the Note Payable to Timberland Venture), which decreased by $13 million, or 9%, to $134 million. This decrease was due primarily to lower interest rates on our variable rate debt. Also, during 2008, we recorded a tax benefit of $27 million compared to a tax benefit of $3 million in the prior year. The higher tax benefit is due primarily to the operating loss in our manufacturing business. The majority of the benefit will result in a tax refund in 2009.

LIQUIDITY

The company believes it has a strong balance sheet and does not foresee any liquidity issues. At December 31, 2008, we had a cash balance of $369 million and had availability of $506 million under our line of credit. During 2008, we generated cash of $420 million from operating activities. Despite the current recession in the U.S., we expect improved cash from operating activity in 2009. We believe based on our strong balance sheet and liquidity, and the cash we expect to generate from operating activity, that we will meet all of our long-term interest and principal payments, required capital expenditures and quarterly dividend distributions in 2009.

KEY ECONOMIC FACTORS IMPACTING OUR RESOURCES AND MANUFACTURED PRODUCTS BUSINESS

Our operating performance for the Resources and Manufactured Products Segments is impacted primarily by the supply and demand for logs and wood products in the United States. The short-term supply of logs is impacted primarily by weather and the level of harvesting activities. The demand for logs in the United States is impacted by housing starts, repair and remodeling activities and the amount of imported lumber, primarily from Canada.

Selected U.S. housing economic data was as follows at December 31:

                                                         2008     2007     2006

       U.S. Housing Starts (in millions)                 0.90     1.35     1.80
       Supply of Existing Homes for Sale (in months)       11       10        6
       30-year Fixed Interest Mortgage Rates (average)    6.0 %    6.3 %    6.4 %

Housing starts have been steadily declining since they peaked at 2.07 million units in 2005. The decline has primarily been driven by falling home prices, increased number of homes in foreclosure, higher standards to qualify for home loans and increased supply of homes for sale. The significant decline in home construction and repair and remodel activities has resulted in an excess supply of lumber and other building products. This excess supply has resulted in weak lumber and plywood prices. Furthermore, the decline in home construction has caused mills to curtail production which has caused downward pressure on sawlog prices.

The U.S. economy slowed significantly during the fourth quarter of 2008 and is currently in a recession. The recession has caused a significant increase in the unemployment rate and very low consumer confidence. As a result, housing

starts for 2009 are expected to decline even further. The lower housing starts may result in more mill curtailments and closures, which could cause sawlog prices to weaken further. Additionally, during the fourth quarter, pulpwood demand began to weaken. The weaker pulpwood demand was due primarily to the decline in consumer spending (primarily packaging materials) and may weaken pulpwood prices if the recession continues.

Over the past several years, fuel prices have generally been rising. Our timber and manufacturing operations have been negatively impacted by rising fuel prices. Operating income in our timber business was negatively affected by $23 million, $2 million and $19 million in 2008, 2007 and 2006, respectively, when compared to the prior year due to rising fuel costs and longer hauling distances. However, fuel prices declined significantly during the second half of 2008 to price levels comparable with the fourth quarter of 2007. We expect fuel prices in 2009 to be lower than fuel prices in 2008.

REAL ESTATE SALES AND DEVELOPMENT PROPERTIES

We estimate that included in the company's approximately 7.4 million acres of timberlands at December 31, 2008, are about 1.5 million acres of higher value timberlands which are expected to be sold and/or developed over the next 15 years for recreational, conservation or residential purposes. Included within the 1.5 million acres of higher value timberlands are approximately 1 million acres we expect to sell for recreational uses, approximately 350,000 acres we expect to sell for conservation and approximately 200,000 acres that may be developed by our real estate development business. In addition, the company has approximately 250,000 acres of non-strategic timberlands, which are expected to be sold over the next five years. Some of our real estate activities, including our real estate development business, are conducted through our wholly-owned taxable REIT subsidiaries.

During 2008, we sold approximately 92,000 acres of non-strategic timberlands, approximately 175,000 acres for conservation purposes and approximately 46,000 acres of higher and better use / recreational properties. We anticipate selling up to 250,000 acres in 2009 and may adjust the type and geographic location of properties sold to respond to areas with active markets. During 2009 our average price per acre for higher and better use / recreational properties is likely to be lower than the price per acre we realized during 2008 primarily due to an increased focus in markets with lower value recreational properties. As a result of the recession, demand in regions with higher value recreation properties has significantly weakened. As a consequence of the weak demand for higher value recreational properties, we have removed some of our best higher and better use / recreational properties from the market. If the U.S. economy remains in a recession for an extended period of time, demand for our rural timberlands could be impacted.

During 2008, we sold approximately 175,000 acres of conservation properties for $200 million compared to selling approximately 32,000 acres for $42 million in 2007. The increase was due primarily to selling approximately 130,000 acres in Montana to a conservation buyer for $150 million. Also, in February 2009, we received $250 million from the same buyer from the sale of approximately 110,000 acres. We expect the final phase of this three-phase deal to close in 2010 for $89 million covering 70,000 acres.

Our land development business slowed dramatically in 2008 as the economy weakened causing a significant decrease in the demand for these properties. Revenue from sales of development properties was $7 million during 2008. We expect sales in 2009 to approximate the 2008 level and do not expect significant sales of development properties to occur until there is an improvement in consumer confidence and the U.S. economy.

HARVEST LEVELS

The volume of trees we harvest each year and the percentage of sawlogs and pulpwood (product mix) included in our annual harvest also impact our operating performance. During 2008, we harvested a total of 19.6 million tons compared to a total of 20.4 million tons during 2007. We expect harvest levels during 2009 to range between 16 and

30 | PLUM CREEK 2008 FORM 10-K

17 million tons. The expected decline in harvest levels in 2009 is due primarily to contributing 454,000 acres to the Timberland Venture and increasing pulpwood harvests in prior years to take advantage of favorable prices. Future harvest levels may vary from historic levels due to weaker than expected markets, to take advantage of favorable prices or due to factors outside of our control, such as weather and fires. Future harvest levels may also be impacted by our sale of timberlands and the extent to which proceeds are reinvested in core timberlands.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Under different assumptions or conditions, actual results may differ from these estimates.

We believe the following critical accounting policies affect our most significant judgments and estimates used in preparation of our consolidated financial statements:

REVENUE RECOGNITION FOR TIMBER SALES

Timber sales revenues are recognized when legal ownership and the risk of loss transfer to the purchaser and the quantity sold is determinable. We sell timber under delivered log agreements and through sales of standing timber (or "stumpage") using pay-as-cut sales contracts, timber deed sales and lump-sum sale agreements.

(1) Delivered Log Sales. Under a delivered log sale agreement, we harvest the timber and deliver it to the buyer. Revenue is recognized when the log is delivered as risk of loss and title transfer to the buyer. With delivered log sales, we incur the cost of logging and hauling.

(2) Pay-as-Cut Sales Contracts. Pay-as-cut sales contracts are agreements in which the buyer agrees to purchase and harvest specified timber on a tract of land for an agreed upon price for each type of tree over the term of the contract (usually 12 to 18 months). In some cases, an advance is received in connection with pay-as-cut sales contracts. In other cases, the buyer agrees to harvest only certain trees on a tract of land. Under pay-as-cut sales contracts, the buyer is responsible for all logging and hauling costs. Revenue is recognized when the timber is harvested, as title and risk of loss has transferred to the buyer. Total revenue recognized under a pay-as-cut sales contract is the total volume of wood removed multiplied by the unit price for each type of tree.

(3) Timber Deeds. Timber deed sales are agreements in which the buyer agrees to purchase and harvest specified timber on a tract of land over the term of the contract (usually 12 to 18 months). Unlike a pay-as-cut sales contract, risk of loss and title to the trees transfer to the buyer when the contract is signed. The buyer also pays the full purchase price when the contract is signed. Under a timber deed, the buyer is responsible for all logging and hauling costs. Revenue from a timber deed sale is recognized when the contract is signed. Timber deeds are generally marketed and sold to the highest bidder. Bids are typically based on a timber cruise which is an estimate of the total volume of timber on a tract of land broken down by the various types of trees (such as softwood sawlogs, hardwood pulpwood, etc.). Total revenue recognized under a timber deed is the amount of the highest bid and is not dependent upon the volume or types of trees actually harvested.

(4) Lump-sum Sale Agreements. Under a lump-sum sale agreement, the buyer and seller agree to a total ("lump-sum") price for all the timber available for harvest on a tract of land. Generally, the lump-sum price is paid when the contract is signed. Title to the timber and risk of loss transfers to the buyer as the timber is harvested. Lump-sum sales are generally marketed and sold to the highest bidder. Bids are typically based on a timber cruise. Under a lump-sum sale, the buyer is responsible for all logging and hauling costs. Total revenue recognized under a

lump-sum sale contract (usually 12 to 18 months) is the amount of the highest bid, and is not dependent upon the volume or type of trees actually harvested.

Unlike timber deed sales, revenue is recognized under a lump-sum sale agreement as the timber is cut. We estimate the amount of revenue to recognize each month based on actual harvested volume compared to the total volume available for harvest according to the timber cruise. We generally receive weekly information from the buyer reporting how much volume has been harvested. Additionally, we gather information by observing the tract to estimate the timber volume harvested. In most cases, the total volume harvested from a tract of land is different than the volume estimated in the timber cruise. If the total volume harvested is greater than the cruise-estimated volume, we will stop recognizing revenue once the total revenue recognized is equal to the total lump-sum contract price. No revenue will be recognized for volumes harvested in excess of the cruise-estimated volume. If the total volume removed is less than the cruise-estimated volume, an adjustment will be recorded in the month in which we learn of the difference. The adjustment is an increase in revenue equal to the difference between the total revenue recognized to date and the total lump-sum contract price.

The following table summarizes amounts recognized under each method from sales to external customers in the company's consolidated financial statements for the years ended December 31 (in millions):

                                               2008     2007
                        Revenues from:
                        Delivered log sales   $  654   $  682
                        Pay-as-cut sales      $   37   $   42
                        Timber deed sales     $   20   $   17
                        Lump-sum sales        $    -   $    6

Substantially all of our timber sales in the Northern Resources Segment are under delivered log sale agreements. In our Southern Resources Segment, approximately 12% of our timber sales in 2008 and in 2007 consisted of pay-as-cut sales contracts, timber deed sales or lump-sum sales. Since under pay-as-cut sales contracts, timber deed sales and lump-sum sales the buyer is responsible for the logging and hauling costs, the operating profit as a percentage of revenue is typically higher in our Southern Resources Segment.

REAL ESTATE SALES

As of December 31, 2008, we estimate that included in the company's approximately 7.4 million acres of timberlands are about 1.5 million acres of higher value timberlands, which are expected to be sold and/or developed over the next 15 years for recreational, conservation, or residential purposes. Included within the 1.5 million acres of higher value timberlands are approximately 1 million acres we expect to sell for recreational uses, approximately 350,000 acres we expect to sell for conservation and approximately 200,000 acres that may be developed by our real estate development business. In addition, the company has approximately 250,000 acres of non-strategic timberlands, which are expected to be sold over the next five years. The timing of real estate sales is a function of many factors, including the general state of the economy, demand in local real estate markets, the ability to obtain entitlements, the number of properties listed for sale, the seasonal nature of sales (particularly in the northern states), the plans of adjacent landowners, our expectation of future price appreciation, the timing of harvesting activities, and the availability of government and not-for-profit funding. As a result, the timing of our real estate sales may materially impact our reported operating income and net income.

During 2008, the Real Estate Segment reported an operating profit percentage of approximately 57%. We estimate our Real Estate Segment's annual operating profit percentage could range from 35% to 70% of revenues. The

32 | PLUM CREEK 2008 FORM 10-K

operating profit percentage depends on the nature of the interest sold and how much the market value of the property has risen over its book value. For example, the sale of conservation easements will generally have an operating profit percentage of close to 100% because historically no book basis was allocated to these types of sales. Sales of recently acquired properties will generally have relatively lower operating profit percentages while sales of properties held for a long time will tend to have relatively higher operating profit percentages. Sales of timberlands owned by Plum Creek prior to The Timber Company merger, which, for accounting purposes, were deemed acquired as of the merger date, will thus have lower operating profit percentages since these properties were recorded at appraised value as of October 2001.

In connection with major timberland acquisitions, we are generally not able to identify our future real estate sales. However, while our purchase price allocation and related appraisals reflected greater values for real estate which may be sold in the future for uses which have a higher value than timber production, we are generally not able to identify specific properties. Therefore, in connection with our purchase price allocation for timberland acquisitions, the greater values for real estate are allocated proportionately among all the acres acquired, except when we can specifically identify properties. In general, however, timberlands are acquired primarily for long-term use in our timber operations and specific properties cannot be identified in advance because their value is dependent upon numerous factors, most of which are not known at the acquisition date, including current and future zoning restrictions, current and future environmental restrictions, future changes in demographics, future changes in the economy, current and future plans of adjacent landowners, and current and future funding of government and not-for-profit conservation and recreation programs. We believe that current and future results of operations could be materially different under different purchase price allocation assumptions, and generally, when we acquire properties, we do not have the ability, with any level of precision, to estimate which of the acquired properties will someday sell for more than their underlying timber production value.

IMPAIRMENT OF LONG-LIVED ASSETS

We evaluate our ability to recover the net investment in long-lived assets in accordance with Statement of Financial Accounting Standards ("SFAS") No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. SFAS No. 144 requires recognition of an impairment loss in connection with long-lived assets used in a business when the carrying value (net book value) of the assets exceeds the estimated future undiscounted cash flows attributable to those assets over their expected useful life. Impairment losses are measured by the extent to which the carrying value of a group of assets exceeds the fair value of such assets at a given point in time. When the fair values of the assets are not available, we estimate the fair values by using the discounted expected future cash flows attributable to the assets. The expected future cash flows are discounted at a risk-adjusted rate of interest. Furthermore, SFAS No. 144 requires recognition of an impairment loss in connection with long-lived assets held for sale when the carrying value of the assets exceeds an amount equal to their fair value less selling costs.

Since 2000, we have grown substantially through acquisitions. The purchase price of these acquisitions has been allocated to our Timber and Timberlands (including Assets Held for Sale and Real Estate Development Properties) and Property, Plant and Equipment. The allocation of the purchase price is highly subjective. Management is required to estimate the fair values of acquired assets and liabilities as of the acquisition date. Subsequent to the original allocation, these assets are tested for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable through future operations. SFAS No. 144 requires that long-lived assets be grouped and evaluated for impairment at the lowest level for which there are independent cash flows. We track cash flows for our 7.4 million acres of timberlands by grouping them into seven geographic areas in the Northern Resources Segment and six geographic areas in the Southern Resources Segment. Additionally, we track cash flows for each of our ten manufacturing facilities.

(1) Timber and Timberlands Used in Our Business. SFAS No. 144 provides that for assets used in a business, an impairment loss is recorded only when the carrying value of those assets is not recoverable through future operations. The recoverability test is based on undiscounted future cash flows over the expected life of the assets. We use one harvest cycle (which ranges between 20 and 90 years) for evaluating the recoverability of our timber and timberlands. Because of the inherently long life of timber and timberlands, we do not expect to incur an impairment loss in the future for the timber and timberlands used in our timber business.

(2) Timber and Timberlands Held for Sale. SFAS No. 144 provides that an impairment loss is recognized for long-lived assets held for sale when the carrying value of those assets exceeds an amount equal to its fair value less selling costs. An asset is generally considered to be held for sale when we have committed to a plan to sell the asset, the asset is available for immediate sale in its present condition, we have initiated an active program to locate a buyer, and the sale is expected to close within one year. During 2008, the above criteria were met by a number of our timberland properties, and we recognized impairment losses of $1 million for certain of these properties. Similarly, we recognized impairment losses of $1 million in 2007 and $2 million in 2006 in connection with timberlands held for sale (see Note 5 of the Notes to Consolidated Financial Statements.) We expect to continue to sell or exchange non-strategic timberlands to other forest products companies or non-industrial investors, and it is probable that we will recognize, in accordance with SFAS No. 144, additional impairment losses in the future in connection with sales of non-strategic timberlands.
