Part I

When we refer to we, us, our, the company or Plum Creek, we
mean Plum Creek Timber Company, Inc. and its consolidated subsidiaries. References in Items 1 through 7 to Notes to Financial Statements refer to the Notes to the Consolidated Financial Statements of Plum Creek Timber Company, Inc. included in
Item 8 of this form.

ITEM 1. BUSINESS

Industry Overview

GENERAL

The timber industry provides raw material and conducts resource management activities for the paper and forest products industry, including the planting,
fertilizing, thinning, and harvesting of trees and the marketing of logs. Logs are marketed and sold either as sawlogs to lumber and other wood products manufacturers or as pulplogs to pulp and paper manufacturers or producers of oriented strand
board (OSB). The timber industry possesses several unique characteristics that distinguish it from the broader paper and forest products industry, which we believe makes timber an attractive asset class, including the following:

Renewable Resource. Timber is a growing and renewable
resource that, when properly managed, increases in volume and value as it grows over time. Larger diameter trees command a higher price than smaller trees because they may be converted to higher value end-use products such as lumber and plywood.

Predictable and Improving Growth Rates.Predictable biological growth is an attractive feature of timberland assets because it contributes to predictable, long-term harvest planning. The development and application of intensive forest management practices continue to
improve biological growth rates.

Harvest Flexibility.Timberland owners have some flexibility to increase their harvests when prices are high and decrease their harvests when prices are low, allowing timberland owners to maximize the long-term value of their growing resource base.

Historical Price Appreciation.Due to
growing demand combined with limitations on supply caused by, among other factors, environmental restrictions and urban sprawl, prices for softwood timber have exhibited a compound annual growth rate of approximately 4% from 1982 through 2006.

SUPPLY AND DEMAND DYNAMICS

There are five primary end-markets for most
of the timber harvested in the United States: products used in new housing construction; products used in the repair and remodeling of existing housing; products for industrial uses; raw material for the manufacture of pulp and paper; and logs for
export.

Supply.Timber supply can
fluctuate based upon a variety of factors. The supply of timber is limited, to some extent, by the availability of timberlands. The availability of timberlands, in turn, is limited by several factors, including government restrictions relating to
environmental regulation and land use, alternate uses such as agriculture, and expansion of population centers. The large amounts of capital and length of time required to create new timberlands also limits timber supply.

Over the long-term, timber supply increases when modern forestry techniques increase productivity of timberlands and when some marginal agriculture lands revert to
timberlands or are planted as forests for conservation purposes. In certain regional markets, log supply can expand when log imports increase relative to log exports.

Demand.The demand for timber is directly related to the underlying demand for pulp and paper
products, lumber, panel and other wood related products. The demand for pulp and paper is largely driven by general macroeconomic conditions, including population growth, per-capita income levels, and industry capacity. The demand for lumber and
manufactured wood products is affected primarily by the level of new residential construction activity and repair and remodeling activity, which, in turn, is impacted by changes in general economic and demographic factors, including population,
interest rates for

home mortgages and construction loans. The demand for United States timber is also impacted by the amounts of pulp and paper products, lumber, panel and
other wood products that are imported into the United States. Significant factors determining the volume of products shipped into the United States by foreign producers are currency valuation shifts as well as tariffs and quotas.

Our Business

We are the largest private timberland owner in the United States, with
8.2 million acres of timberlands located in 18 states. Our timberlands are well diversified, not only geographically, but also by species mix and age distribution. Growth rates vary depending on species, location, age and forestry practices. We
manage our timberlands in two business segments: the Northern Resources Segment, consisting of timberlands in Maine, Michigan, Montana, New Hampshire, Oregon, Washington, West Virginia and Wisconsin; and the Southern Resources Segment, consisting of
timberlands in Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina and Texas. In addition, our Other Segment includes our natural resource businesses that focus on opportunities relating to mineral
extraction, natural gas production and communication and transportation rights of way resulting from our extensive property ownership. The Real Estate Segment comprises our sales of higher and better use timberlands and sales of non-strategic
timberlands, some of which are sold through our wholly-owned taxable REIT subsidiaries. Our Real Estate Segment includes development of certain properties, internally and through joint ventures, which is conducted through our wholly-owned taxable
REIT subsidiaries.

Our Manufactured Products Segment, also conducted through our wholly-owned taxable REIT subsidiaries, includes four lumber mills, two
plywood plants, two medium density fiberboard (MDF) facilities, and two lumber remanufacturing facilities. These facilities, strategically located near our timberlands in Montana, convert logs to lumber, plywood and other wood products,
and convert chips, sawdust and wood shavings to MDF. The Manufactured Products Segment also has established a network of nation-wide field inventory points where inventory is held for customers at either independent public warehouses or on
consignment at customer distribution centers.

OUR VALUE GROWTH STRATEGY

We seek to maximize the value of our assets by harvesting trees or selling land only when they have achieved optimal economic value. Our value growth strategy is guided by specific operating objectives, including maximizing the value of our
current timberlands through intensive forest management and optimizing our resource base through acquisitions and divestitures, and practicing environmentally responsible resource stewardship. Our value growth strategy includes the following key
elements:

Focus on Maximizing the Value of Our Resource Base Through Intensive Management of Our
Timberlands.We view our core timber resource base as a renewable asset with substantial inherent value. We seek to manage our timberlands in a manner that optimizes the
balance among current cash flows, the biological growth of our timber and prudent environmental management. Our management approach employs advanced forest management practices, including the use of a computerized timber inventory system, thinning
and fertilization, and the development and use of genetically improved seedlings. Tree growth rates vary by region because of differences in weather, climate and soil conditions. Newly-planted seedlings take 20 to 30 years to reach harvest maturity
in the Southern United States, 45 to 60 years in the Northwestern United States, 45 to 70 years in the Northeastern United States and 70 to 90 years in inland regions of the Western United States, depending on the desired product.

Pursue Acquisitions of High-Quality Timberlands.The United States timber market is highly fragmented. We believe that there will continue to be timberland acquisition opportunities due to the desire among some paper and forest product companies to sell their timberland
assets and the difficulties faced by some small timberland owners in efficiently managing their timberlands. We believe we are well positioned to compete for high-quality timberlands because:



| |  | We are an attractive strategic partner for integrated forest products companies seeking to sell their timberlands because we do not compete with their pulp or paper
manufacturing operations and we are willing to enter into long-term supply agreements;

| |  | We can structure acquisitions on a tax-efficient basis through the issuance of common stock, limited partnership interests in our operating partnership, or
installment notes, giving sellers the ability to defer some or all of the taxes otherwise payable upon a sale;
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | The geographic reach of our operations enhances our awareness of new acquisition opportunities and our knowledge of environmental concerns, market dynamics, timber
productivity and other factors important in valuing timberlands and operations in each region;
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Our reputation for prudent environmental management makes us attractive to sellers concerned with continued environmentally responsible forest management; and
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | We maintain a conservative capital structure, which provides the flexibility to ensure ready access to capital.
|- |  | ---------------------------------------------------------------------------------------------------------------

Our disciplined acquisition strategy has allowed us to expand and diversify our timberland holdings, as well as increase our cash flow. Since 1989, we have increased our
timber holdings from 1.4 million acres to approximately 8.2 million acres at December 31, 2006. These acquisitions have enhanced our operating flexibility and reduced our exposure to regional timber market fluctuations. Our strategy
is to continue to make strategic acquisitions that are accretive to cash flow.

Realize the Value of
Selected Properties Through Sale or Exchange.At the same time that we pursue timberland acquisitions, we continually review our timberland portfolio to identify properties that are
no longer strategic to our long-term timberland operations or that may have higher and better uses other than as commercial timberlands. We estimate that included in the companys approximately 8.2 million acres of timberlands are about
1.7 million acres of higher and better use timberlands, which are expected to be sold and/or developed over the next 15 years for residential, recreational or conservation purposes. In addition, the company has approximately 400,000 acres of
non-strategic timberlands, which are expected to be sold over the next five years. In the meantime, these timberlands continue to be used productively in our business of growing and selling timber. Included within the 1.7 million acres of
higher and better use timberlands are approximately 225,000 acres that will be developed by the companys wholly-owned taxable REIT subsidiaries. Properties developed internally by the company will generally be low-intensity development limited
to obtaining entitlements and investing in infrastructure such as roads and utilities. Larger and more complicated projects, such as destination resorts and master planned communities, will be developed through joint venture arrangements in which we
are the minority partner and our involvement is limited to selling and/or contributing timberlands and exercising certain protective rights. Our real estate development business is conducted through our wholly-owned taxable REIT subsidiaries.

We may sell or exchange timberlands that have high environmental or other public values and reinvest in timberlands that are more suitable for commercial
timber management. In addition, we may sell conservation easements that limit development rights, but ensure that the timberlands will be maintained as a working forest in perpetuity. We may also sell or exchange less strategic timberlands to other
forest products companies or non-industrial investors.

Capture the Value of Non-timber Resources on Our
Properties.As part of our resources business, we focus on realizing the maximum value potential of our extensive property ownership, including opportunities relating to
mineral extraction. Our strategy involves forming strategic alliances with industry specific leaders to identify and pursue such opportunities.

Practice Responsible Environmental Forestry.We believe that environmentally sound management practices contribute to our growth in value by providing greater predictability in the management of our assets. We follow the principles of the
Sustainable Forestry Initiative® program (SFISM) which are aimed at the sound management of all natural resources, including soils, air, watersheds, fisheries and wildlife habitats. These principles are reflected in our habitat planning efforts, which have led to the
implementation of five major habitat conservation agreements under which we manage approximately 1.9 million acres of our timberlands. Our forestry practices on all of our timberlands have been independently audited and certified by
PricewaterhouseCoopers LLP under the SFISMprogram. Our manufacturing practices follow a set of internally developed
environmental principles. See Federal and State Regulations below.

Segment Information

Certain financial information for each business segment is included in Note 14 of the Notes to Financial Statements and is incorporated herein by reference.

NORTHERN RESOURCES SEGMENT

As of December 31, 2006, the Northern Resources Segment encompassed 4.0 million acres of timberlands in
Maine, Michigan, Montana, New Hampshire, Oregon, Washington, West Virginia and Wisconsin, and contained an estimated 126 million tons (43 million cunits) of standing timber. Consistent with industry practices in the North, Plum
Creeks estimated inventory of standing timber includes deductions for visible and hidden defect. Furthermore, Plum Creeks estimated inventory includes volumes in environmentally sensitive areas, where we defer harvest until conditions
permit the removal of trees without adversely affecting the environment.

Logs harvested in the Northern Resources Segment are sold predominately to
domestic mills. Competitors in the domestic log market include the United States Forest Service, the Bureau of Land Management, the Bureau of Indian Affairs, the British Columbia Ministry of Forests, and numerous private individuals, domestic and
foreign industrial timberland owners, and state agencies located in the regions in which we operate. In the Northern Resources Segment, domestic wood and fiber consuming facilities tend to purchase raw materials within a 200-mile radius due to
transportation costs. Competitive factors within a market area generally will include price, species, grade, quality, proximity to wood consuming facilities and the ability to consistently meet customer requirements. We compete based on price and on

During 2006,
approximately 26% of the timber harvested in our Northern Resources Segment was sold pursuant to a supply agreement. We expect this percentage to be approximately 23% during 2007. The volume commitments under these supply agreements may restrict our
ability to sell timberlands in certain areas within our Northern Resources Segment.

SOUTHERN RESOURCES SEGMENT

As of December 31, 2006, the Southern Resources Segment consisted of 4.2 million acres of timberlands (including approximately 309,000 acres of leased land)
located in the states of Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina and Texas, and contained an estimated 156 million tons (44 million cunits) of standing timber. Consistent with
industry practices in the South, Plum Creeks estimated inventory of standing timber includes deductions for visible defect. Furthermore, Plum Creeks estimated inventory includes volume in environmentally sensitive areas, where we defer
harvest until conditions permit the removal of trees without adversely affecting the environment.

Logs in the Southern Resources Segment are sold to third
party mills producing a wide array of forest products, including manufacturers of lumber, plywood, oriented strand board, and pulp and paper products. We compete with numerous private and industrial timberland owners as well as federal and state
agencies across the Southern United States. Due to transportation costs, domestic wood and fiber consuming facilities in the Southern Resources Segment tend to purchase raw material within a 100-mile radius. Competitive factors within our Southern
Resources Segment include price, species, grade, quality, proximity to wood consuming facilities and the ability to consistently meet customer requirements. We compete based on our reputation as a stable and consistent supplier of well-merchandised,
high-quality logs, and on price.

The Southern Resources Segment has several log supply agreements. In general, the agreements require us to supply a
specific volume of timber to certain manufacturing facilities in the U.S. We had the following supply agreements in the Southern Resources Segment as ofDecember 31, 2006:

##### Table of Contents

During 2006, approximately 18% of the timber harvested in our Southern Resources Segment was sold pursuant to a supply
agreement. We expect this percentage to be approximately the same during 2007. The volume commitments under these supply agreements may restrict our ability to sell timberlands in certain areas within our Southern Resources Segment.

REAL ESTATE SEGMENT

We estimate that included in our 8.2 million acres of
timberlands are approximately 1.7 million acres of higher and better use timberlands and about 400,000 acres of non-strategic timberlands. The higher and better use timberlands are expected to be sold over the next 15 years for residential,
recreational or conservation purposes. The non-strategic timberlands are expected to be sold over the next five years. Until the properties are sold, they will continue to be used productively in our business of growing and selling timber.

Included within the 1.7 million acres of higher and better use timberlands are approximately 225,000 acres that may be developed by the company.
Projects developed internally by the company will generally be low-intensity development limited to activities associated with obtaining entitlements and investing in infrastructure, such as roads and utilities. Larger and more complicated projects,
such as destination resorts and master planned communities, will be developed through joint venture arrangements with leading land developers. Our real estate development business is conducted through our wholly-owned taxable REIT subsidiaries. We
compete with numerous sellers of entitled and unentitled land in hundreds of local markets.

We have identified approximately 95,000 acres with an estimated
125 properties that we expect to develop internally over the next 15 years. At December 31, 2006, we had 13 internal development properties, or approximately 3,600 acres entitled and an additional 32 properties, or approximately 24,000 acres,
in the planning process. Listed below is a summary of our entitled or developed properties as ofDecember 31, 2006:

The company estimates that approximately 130,000 acres will be developed through joint venture arrangements over the next 15 to 20 years. At December 31, 2006, we have entered into six joint venture arrangements with land developers
for three

projects in northeast Florida, two in southeast Georgia, and one in South Carolina. The six joint venture arrangements cover approximately 26,000 acres. The
actual developable acres will be less and will depend upon numerous factors including, but not limited to, zoning restrictions, wetlands, and governmental approvals. We expect these joint venture arrangements will each take from five to fifteen
years to complete all entitlement, development and sales activities. We do not expect significant revenues from these joint ventures during 2007.

MANUFACTURED PRODUCTS SEGMENT

Lumber.We produce a diverse line of softwood lumber products, including common, select and edge-glued boards, studs and finger-jointed studs. Lumber products
manufactured in our two Montana random-length board mills and remanufacturing facility in Idaho are targeted to domestic lumber retailers, such as retail home centers for use in repair and remodeling projects. Lumber from our two Montana studmills
and finger-joint stud remanufacturing plant are targeted to contractor distribution yards for use in home construction. These lumber products are also sold to stocking distributors who serve a wide variety of end uses.

Competition in our lumber markets is based on price and quality and, to a lesser extent, the ability to meet delivery requirements on a consistent long-term basis and to
provide specialized customer service. We compete in domestic lumber markets with many United States, Canadian and European producers. In the past few years, Canadian lumber producers have increased their penetration into the United States market due
to their lower wood fiber costs. Competition from European lumber producers varies from year to year and is significantly impacted by changes in currency exchange rates and ocean freight rates. The lumber market is also subject to competition from
substitute products, such as products made from engineered wood composites, fiber/cement composites, plastics and steel.

Our lumber and plywood mills
produce residual wood chips, sawdust and planer shavings as by-products of the conversion of logs into finished products. The wood chips are sold to regional paper and pulp mills or used in our MDF facilities, which also consume the sawdust and
shavings.

Plywood.Our two
plywood plants in western Montana produce high-grade softwood plywood that we sell primarily into domestic specialized industrial markets, including boat, recreational vehicle, transportation and concrete forming applications. Our plywood products
are generally of higher quality than commodity construction grade products and generally command higher prices in these specialty markets. While some plywood products are sold directly to large industrial customers, the majority is sold via stocking
wholesale distributors. During 2006, we sold approximately 6% of our plywood in Canada. See Lumber above for a discussion of residual wood chips.

##### Table of Contents

Competition within the plywood market is based primarily on price and quality and, to a lesser extent, the ability to
offer a full line of products and meet delivery requirements on a consistent, long-term basis. The domestic plywood market is characterized by numerous large and small producers and is also subject to competition from oriented strand board (OSB), a
less expensive structural wood panel used primarily in commodity construction markets. Due to its low cost, OSB has now captured over 62% of the structural panel market, and this percentage is expected to increase over the next several years as
additional oriented strand board plants are built or existing facilities are expanded. This trend has forced closure of marginal plywood capacity over the past several years. To improve operating performance, some commodity plywood manufacturers
have refocused their products toward the specialty plywood market, resulting in increased competition in the markets we serve. Recently, competition from imported South American plywood has also impacted the high-grade sanded plywood market. We
expect to remain competitive due to our strong customer base, extensive experience in industrial markets, supply of superior quality timber, and reputation for high-quality products.

Medium Density Fiberboard.Our MDF facilities in western Montana supplies high-quality MDF to a wide range of customers throughout North America. Some of the more common uses for our MDF include furniture and cabinet components, architectural
moldings, doors, store fixtures, core material for hardwood plywood, commercial wall paneling and substrate for laminate flooring. Our MDF facilities have a combined capacity of approximately 275 million feet 3/4basis. In 2006, both lines operated near full production capability yielding a combined output of approximately
265 million feet 3/4basis. During 2006, we sold approximately 9% and 4% of our MDF in Canada and Mexico,
respectively.

Outside North America, the MDF industry has undergone dramatic growth in terms of productive capacity and demand for its
products. Manufacturers compete on a global scale on the basis of price, quality, service and the availability of specialty products. Additionally, MDF is a ready substitute for solid wood, hardboard and hardwood plywood in specific applications.
Competition in the North American MDF industry has continued to intensify due to imports from New Zealand, Asia and South America. In addition, the continuing shift of end product production to offshore manufacturing, as has been seen with certain
types of furniture from China and moldings from South America, continues to negatively impact the North American MDF industry.

OTHER SEGMENTNATURAL RESOURCES

We focus on realizing the maximum value potential of our extensive property ownership, including opportunities relating to mineral extraction, natural gas
production and communication and transportation rights of way. This segment represents a diverse array of natural resource products and markets subject to widely varying forms and levels of competition. Our strategy involves forming strategic
alliances with industry specific leaders to identify and pursue such opportunities. We currently receive royalty revenue from the extraction of oil, gas, and minerals from some of our timberlands.

We continue to evaluate a wide variety of non-timber natural resource opportunities, and we expect to continue to negotiate royalty arrangements, leases and joint
ventures to capture the maximum value for all of our non-timber natural resource assets.

Timber Resource Management and Environmental Stewardship

RESOURCE MANAGEMENT

We view our timberlands as assets with substantial inherent value.
We strive to manage them in an economically prudent and environmentally responsible manner to enhance their value. We seek to enhance value by improving the productivity of our forests, controlling harvesting costs, and sorting and merchandising
logs to obtain their highest value.

We use different management techniques in each of our regions, employing a variety of the most cost effective
silvicultural methods available. We expect timber growth rates on our timberlands to continue to improve over time as a result of genetic advances in seedlings, intensive forest management practices such as thinning and fertilization, and the
increasing proportion of our timberlands that are converted from natural forests to actively managed plantations. Technology and forest management advances have increased growth rates and shortened harvest cycles. We believe our focus on intensive
management practices will enhance forest productivity and increase the value of our timberlands over time.

Value can be enhanced on younger timber stands
through thinning operations. Value increases as trees grow and add wood volume. Thinning a timber stand enables the healthier and potentially more valuable trees to grow more rapidly. As trees grow larger, they can be used in higher value
applications such as high-grade lumber, plywood, and furniture. We also

consider the impact of forest management activities on properties with potentially higher and better uses other than long-term timber production, and modify
silviculture and harvest plans accordingly.

Intensive silvicultural applications, including the use of genetically improved seedlings, early and
mid-rotation applications of fertilizers and chemicals to control plant competition, and pre-commercial thinning, will continue to enhance the growth and value of our timberlands. These projects improve not only the growth of the forests, but
enhance the quality of the wood grown, reduce future harvesting costs, and shorten the length of harvest rotations.

It is our policy to ensure that every
acre harvested is promptly reforested. Based on the geographic and climatic conditions of the harvest site, harvested areas may be regenerated naturally by leaving mature trees to reseed the area. Natural regeneration methods are used on a
substantial portion of our timberlands in the Northern Resources Segment. In the Southern Resources Segment, substantially all reforestation is done by planting.

Forests are subject to a number of natural hazards, including damage by fire, hurricanes, insects and disease. Severe weather conditions and other natural disasters can also reduce the productivity of timberlands and disrupt the harvesting
and delivery of forest products. While damage from natural causes is typically localized and would normally affect only a small portion of our timberlands at any one time, these hazards are unpredictable and losses might not be so limited. The size
and diversity of our timberlands, together with our intensive forest management, should help to minimize these risks. Consistent with the practices of other large timber companies, we do not maintain insurance against loss to standing timber on our
timberlands due to natural disasters, but we do maintain insurance for loss of already harvested logs due to fire and other occurrences. During 2005, a loss of $2 million was recorded as a result of hurricane damage.

ENVIRONMENTAL STEWARDSHIP

We
practice environmentally responsible resource management. We adhere to the philosophy that environmentally sound management practices contribute to the companys growth in value by providing greater predictability in the management of its
natural resource assets. We follow the principles and objectives of the Sustainable Forestry Initiative® program (SFISM), which sets forth a comprehensive approach to responsible forest stewardship. Our forestry practices on all of our timberlands have been independently
audited and certified by PricewaterhouseCoopers LLP under the SFISMprogram. The SFISMprogram principles, which can be found on the companys website at www.plumcreek.com, are designed to ensure that
forest management is integrated with the conservation of soil, air and water resources, wildlife and fish habitat, and aesthetics.

Consistent with these
principles, we have actively engaged in habitat conservation planning. The habitats of hundreds of species are protected by several agreements, including numerous species listed as threatened or endangered under the Endangered Species Act. These
agreements, which include Habitat Conservation Plans (HCPs) and other types of conservations agreements, are as follows:

Raw Materials

Our lumber and plywood
facilities obtain approximately two-thirds of their logs from our Montana timberlands. Our timberlands currently supply high-quality logs and preferred timber species to our lumber and plywood facilities, although future harvest levels on our
Montana timberlands are expected to decline. Furthermore, over time the average log size and log quality is expected to decline due to evolving harvest and growth patterns.

Our lumber and plywood facilities have purchased and will continue to source stumpage and logs from external suppliers, including the United States Forest Service, Bureau of Indian Affairs, and state and private
timberland owners. We expect to increase purchases of stumpage and logs from external sources as harvest levels on our Montana timberlands decline. However, harvest levels in and around Montana are also declining, and we may experience a shortage of
logs in the future. The geographic area from which our lumber and plywood facilities obtain logs may expand or contract from year to year as the cost of logs and value of manufactured products fluctuates. (For further discussion of other timber
supply issues, see Federal and State Regulations below.) Our MDF facilities have a consistent supply of chips, sawdust and wood shavings from internal and external sources. However, as a result of declining harvest levels in and around
our MDF facilities, we have had to expand the area in which we purchase chips. This has resulted in longer hauling distances and higher raw material costs. Both MDF and plywood use large quantities of resins, which are procured from a reliable
supplier. Our two lumber remanufacturing facilities (the Montana finger-joint stud plant and the Idaho pine board plant) obtain about 40-50% and 10-20%, respectively, of their lumber raw materials from Plum Creek sawmills, with the remainder being
procured from third-party suppliers.

Competition

Markets for
manufactured forest products are highly competitive in terms of price and quality. Some of our manufactured forest products competitors have substantially greater financial and operating resources. In addition, wood products are subject to
increasing competition from a variety of substitutes, including non-wood and engineered wood products as well as import competition from other worldwide suppliers. We believe we can compete effectively because of our extensive private timber
inventory, our reputation for environmentally responsible forestry, which has positioned us to meet regulatory challenges on a cost-effective basis, our reputation as a dependable, long-term supplier of quality products, our innovative approach to
providing high-quality, value-added products to various retail and industrial niche markets and the integration of our timberlands with efficient manufacturing processes.

Seasonal Effects

Log sales volumes from our Northern Resources Segment are typically at their lowest point in the second quarter of each year when
warming weather thaws and softens roadbeds, thus restricting access to logging sites. Log sales volumes from our Southern Resources Segment are generally at their lowest point during the first quarter of each year, as winter rains limit operations.

Demand for manufactured products is generally lower in the winter quarter when activity in construction markets is slower, and higher in the spring, summer
and fall quarters when construction increases. Working capital varies with seasonal fluctuations.

Federal and State Regulations

GENERAL ENVIRONMENTAL REGULATION

Our operations are subject to federal, state and
local environmental laws and regulations, including laws relating to water, air, solid waste and hazardous substances and the requirements of the Federal Occupational Safety and Health Act and comparable state statutes relating to the health and
safety of our employees. Although we believe that we are in material compliance with these requirements, there can be no assurance that we will not incur significant costs, civil and criminal penalties, and liabilities, including those relating to
claims for damages to property or natural resources, resulting from our operations. We maintain environmental and safety compliance programs and conduct regular internal and independent third-party audits of our facilities and timberlands to monitor
compliance with these laws and regulations.

ENDANGERED SPECIES

The Endangered
Species Act protects species threatened with possible extinction. A number of species indigenous to our timberlands have been listed as threatened or endangered or have been proposed for one or the other status under the Endangered Species Act. As a
result, our activities in or adjacent to the habitat of these species may be subject to restrictions on the harvesting of timber, reforestation activities and the construction and use of roads.

We have received incidental take permits and similar authorizations pursuant to our Habitat Conservation Plans and other conservation agreements (detailed in
Environmental Stewardship above) from the U.S. Fish and Wildlife Service (and from National Marine Fisheries Service, in the case of anadromous species) that in total cover our forest management on 1.6 million acres in the Northern
Resources Segment and 0.9 million acres in the Southern Resources Segment. As required by the Endangered Species Act, we prepared Habitat Conservation Plans that will govern our management activities on the timberlands covered by the plans in
these regions during their respective terms. The Habitat Conservation Plans require us to maintain certain levels of wildlife and fish habitat, and to take numerous other mitigation measures, including the protection of riparian areas. With the
implementation of these mitigation measures, we are authorized to conduct forestry practices that are consistent with the conservation plans, even though they may have an adverse impact on the listed species covered by the plans.

During 2006, we completed negotiating an agreement with the Fish and Wildlife Service to address the presence of red-cockaded woodpeckers located on or near some of our
Southern properties, which are listed as endangered under the Endangered Species Act. Under the agreement, which covers approximately 0.6 million acres outside of our Red-Cockaded Woodpecker Habitat Conservation Plan, we have agreed to relocate
red-cockaded woodpeckers and to actively manage habitat in a designated conservation area, significantly increasing long-term population survival. In exchange, we have gained increased flexibility to manage our surrounding timberlands for commercial
timber production.

Although the Habitat Conservation Plans and other conservation agreements have been implemented and are functioning as expected, there
can be no assurance that they will remain in force or be sufficient to protect us against subsequent changes to the Endangered Species Act. Nor can there be any assurance that the Habitat Conservation Plans and the conservation agreements,
individually or collectively, will be sufficient to protect us against the listing of additional species, or against changes to other applicable laws and regulations. Any of these changes could materially and adversely affect our operations.

CLEAN WATER

The Clean Water Act and comparable state laws, regulations
and best management practices programs protect water quality. As a result, our resource management activities adjacent to rivers and streams as well as the point source discharges from our manufacturing facilities are subject to strict regulation.
Most silvicultural activities are defined by regulation to be non-point sources and thus do not require federal permits from the Environmental Protection Agency, but rather are subject to state regulation and best management practices
programs. Recent litigation in numerous courts, however, has challenged this silvicultural exemption under the Clean Water Act. Accordingly, there can be no assurance that our forest management activities will not be subject to increased regulation
under the Clean Water Act in the future.

At this time, we believe that federal and state laws and regulations related to the protection of endangered
species and clean water will not have a material adverse effect on our financial position, results of operations or liquidity. We anticipate, however, that increasingly strict laws and regulations relating to the environment, natural resources and
forestry operations, as well as increased social concern over environmental issues, may result in additional restrictions on us leading to increased costs, additional capital expenditures and reduced operating flexibility. We believe that our
experience provides us a relative competitive advantage in managing environmental risks.

In connection with the October 6, 2001 merger with The Timber
Company, Plum Creek agreed to indemnify Georgia-Pacific for substantially all of the liabilities attributed to The Timber Company. During 2003, Georgia-Pacific provided Plum Creek with information about the existence of mine tailings and
approximately 4.5 billion gallons of acidic surface water on approximately 90 acres in Hot Spring County, Arkansas, on former Georgia-Pacific properties. Barite mining and related activities were conducted on the site between 1939 and 1981 in
part by lessees of an entity that was acquired by Georgia-Pacific. The site is currently being investigated and no remediation plan has yet been approved. No amounts have been accrued for this potential liability. Furthermore, to the extent Plum
Creek is required to indemnify Georgia-Pacific for its

share of the remediation costs, Plum Creek may be able to recover a portion of its cost from Georgia-Pacifics insurance policy, or indemnity
obligations of the various lessees that conducted mining operations on the property, or both.

TIMBERLANDS

Our forest practices are and will in the future be subject to specialized statutes and regulations in the states where we operate. Many of these states have enacted laws
that regulate forestry operations, such as growing, harvesting and processing activities on timberlands. Among other requirements, these laws impose some reforestation obligations on the owners of timberlands. Several states require prior
notification before beginning harvesting activities. A number of states require a regulatory review taking from 15 to 30 days or more prior to harvesting, depending upon the environmental and other sensitivities of the proposed activity. Other state
laws and regulations control the following activities: slash burning and harvesting during fire hazard periods; activities that affect water courses or are in proximity to inland shorelines; and activities that affect water quality, and some grading
and road construction activities.

Encumbrances

Under the terms of our
debt agreements, we have agreed not to pledge, assign or transfer timberlands, except under limited circumstances. The holders of our $13 million face value 11.125% First Mortgage Notes due 2007 have a first mortgage lien on a significant portion of
our lumber, plywood and MDF facilities.

The title to our timberlands does not always include the related hard rock mineral interests or oil and gas rights.
Title to the timberlands is subject to presently existing easements, rights of way, flowage and flooding rights, servitudes, hunting and other leases, licenses and permits, none of which materially adversely affect the value of the timberlands or
materially restrict the harvesting of timber or other operations.

Employees

We currently have approximately 800 salaried and 1,200 non-union hourly employees. We believe that our employee relations are good. Our wage scale and benefits are generally competitive with other forest products companies. The planting of
seedlings and the harvesting and delivery of logs are conducted by independent contractors who are not our employees.

Certain Corporate Governance and Other
Available Information

The company maintains a code of ethics entitled the Plum Creek Code of Conduct, which applies to each director and to all of
the companys employees including the principal executive officer, the principal financial officer and the principal accounting officer. In addition, each committee of the companys board of directors is governed by a charter. The Plum
Creek Code of Conduct and the governing charters of the Audit, Compensation, and Corporate Governance and Nominating committees, along with the companys Corporate Governance Guidelines, can be found in the Corporate Governance
section of the companys website accessible to the public at www.plumcreek.com.To find this section, click on the Investors link and then the Corporate Governance link. The company will post any amendments to, or
waivers from, its Code of Conduct (to the extent applicable to any director or any of the companys executive officers, including the principal executive officer, principal financial officer or principal accounting officer) at this
location on its website. In addition to these documents, the companys annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and reports concerning transactions in the companys stock by
directors and certain officers of the company, and any amendments to those reports, can also be found on our website by first clicking the Investors link, then the Earnings/Financial Publications link and finally the

Stock Exchange Listing Compliance and SEC Certifications

On May 12, 2006, Rick R. Holley, as President and Chief Executive Officer of the company, submitted an unqualified certification to the New York Stock Exchange stating that, as of that date, he was not aware of
any violation by the company of the New York Stock Exchange Corporate Governance Listing Standards. Additionally, the company has filed with the Securities and Exchange Commission the Chief Executive Officer and Chief Financial Officer
certifications required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, as amended.

ITEM 1A. RISK FACTORS

Business and Operating Risks

THE CYCLICAL NATURE OF OUR BUSINESS COULD ADVERSELY AFFECT OUR RESULTS OF OPERATIONS

Our results of operations are affected by the cyclical nature
of the forest products industry. Historical prices for logs and manufactured wood products have been volatile, and we, like other participants in the forest products industry, have limited direct influence over the time and extent of price changes
for logs and wood products. The demand for logs and wood products is affected primarily by the level of new residential construction activity and, to a lesser extent, repair and remodeling activity and other industrial uses. The demand for logs is
also affected by the demand for wood chips in the pulp and paper markets. These activities are, in turn, subject to fluctuations due to, among other factors:



| |  | changes in domestic and international economic conditions;
|- |  | ----------------------------------------------------------



| |  | interest rates;
|- |  | ---------------



| |  | population growth and changing demographics; and
|- |  | ------------------------------------------------



| |  | seasonal weather cycles (e.g., dry summers, wet winters).
|- |  | ---------------------------------------------------------

Decreases in the level of residential construction activity generally reduce demand for logs and wood products. This results in lower revenues, profits and cash flows. In addition, industry-wide increases in the supply of logs and wood
products during favorable price environments can also lead to downward pressure on prices. Timber owners generally increase production volumes for logs and wood products during favorable price environments. Such increased production, however, when
coupled with even modest declines in demand for these products in general, could lead to oversupply and lower prices.

Our results of operations may also be
subject to global economic changes as global supplies of wood fiber shift in response to changing economic conditions. Changes in global economic conditions that could affect our results of operations include, but are not limited to, new timber
supply sources and changes in currency exchange rates, foreign and domestic interest rates and foreign and domestic trade policies.

In addition, changes in
our ability to sell or exchange non-strategic timberlands and timberland properties that have higher and better uses at attractive prices, or changes that adversely affect our ability to execute on certain real estate development activities
conducted through our wholly-owned taxable REIT subsidiaries, could have a significant effect on our results of operations.

The following factors, among
others, may adversely affect the timing and amount of our income generated by our land sales or our real estate development activities:



| |  | general economic conditions;
|- |  | ----------------------------



| |  | availability of funding for governmental agencies, developers, conservation organizations, individuals and others to purchase our timberlands for conservation,
recreation, residential or other purposes;
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | local real estate market conditions, such as oversupply of, or reduced demand for, properties sharing the same or similar characteristics as those in our portfolio;
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | competition from other sellers of land and real estate developers;
|- |  | ------------------------------------------------------------------



| |  | weather conditions or natural disasters having an adverse effect on our properties;
|- |  | -----------------------------------------------------------------------------------



| |  | relative illiquidity of real estate investments;
|- |  | ------------------------------------------------



| |  | changes in interest rates;
|- |  | --------------------------



| |  | impact of federal, state and local land use and environmental protection laws;
|- |  | ------------------------------------------------------------------------------



| |  | changes in laws, regulations or the regulatory environment affecting tax, real estate and zoning; or
|- |  | ----------------------------------------------------------------------------------------------------



| |  | our ability to obtain all land use entitlements and other permits necessary for our development activities.

##### Table of Contents

THE FOREST PRODUCTS INDUSTRY IS HIGHLY COMPETITIVE

The forest products industry is highly competitive in terms of price and quality. Wood products are subject to increasing competition from a variety of substitute products, including non-wood and engineered wood
products. For example, plywood markets are subject to competition from oriented strand board, and U.S. lumber and log markets are subject to competition from other worldwide suppliers.

Historically, Canada has been a significant source of lumber for the U.S. market, particularly in the new home construction market. A trade agreement concerning lumber imports between the U.S. and Canada expired in
March 2001. Soon thereafter, a U.S. industry coalition, of which Plum Creek is a member, submitted anti-dumping and countervailing duty petitions to the International Trade Commission and the U.S. Department of Commerce alleging that Canadian lumber
exports to the U.S. were unfairly subsidized and that lumber from Canada was being dumped into the U.S. market. In response to these petitions, the U.S. Department of Commerce imposed both countervailing and anti-dumping duties. Canada appealed the
imposition of these duties to both NAFTA and the WTO.

On October 13, 2006, a definitive agreement was signed establishing a system of tiered taxes
and/or volume restrictions which will be in effect for a period of seven years. Notwithstanding the signing of a definitive agreement between the U.S. and Canadian governments, there can be no assurance that the agreement will effectively create a
fair trade environment. Therefore, downward pressure on domestic timber and lumber prices caused by Canadian imports could continue or increase.

OUR CASH DIVIDENDS
ARE NOT GUARANTEED AND MAY FLUCTUATE

We have elected to be taxed as a REIT under sections 856-860 of the United States Internal Revenue Code of 1986, as
amended. Generally, REITs are required to distribute 90% of their taxable income. However, REITs are required to distribute only their ordinary taxable income and not their net capital gains income. Accordingly, we do not believe that we are
required to distribute material amounts of cash given that substantially all our taxable income is treated as capital gains income. To the extent capital gains income is not distributed to shareholders, a REIT would be subject to a 35% federal
corporate income tax and applicable state income taxes on the undistributed capital gain income. In addition, the shareholders would be required to report their share of the retained capital gains income on their respective income tax returns, but
would receive a refundable tax credit for their share of the tax paid at the corporate level.

Our Board of Directors, in its sole discretion, determines
the amount of the quarterly dividends (including the determination of whether to retain net capital gains income) to be provided to our stockholders based on consideration of a number of factors including, but not limited to, our results of
operations, cash flow and capital requirements, economic conditions, tax considerations, borrowing capacity and other factors, including debt covenant restrictions that may impose limitations on cash payments, future acquisitions and divestitures,
harvest levels, changes in the price and demand for our products and general market demand for timberlands including those timberland properties that have higher and better uses. Consequently, our dividend levels may fluctuate.

WE MAY BE UNSUCCESSFUL IN CARRYING OUT OUR ACQUISITION STRATEGY

We intend to pursue
acquisitions of strategic timberland properties. As with any investment, our future acquisitions, if any, may not perform in accordance with our expectations. In addition, we anticipate financing such acquisitions through cash from operations,
borrowings under our unsecured credit facilities, proceeds from equity or debt offerings (including offerings of limited partnership units by our operating partnership) or proceeds from asset dispositions, or any combination thereof. Our inability
to finance future acquisitions on favorable terms or the failure of any acquisitions to conform to our expectations, could adversely affect our results of operations.

WE DEPEND ON EXTERNAL SOURCES OF CAPITAL FOR FUTURE GROWTH

Our ability to finance growth is dependent to a significant degree on external sources
of capital. Our ability to access such capital on favorable terms could be hampered by a number of factors, many of which are outside of our control, including, without limitation, a decline in general market conditions, increases in interest rates,
an unfavorable market perception of our growth potential, a decrease in our current or estimated future earnings or a decrease in the market price of our common



10K -16-

##### Table of Contents

stock. In addition, our ability to access additional capital may also be limited by the terms of our existing indebtedness, which, among other things,
restricts our incurrence of debt and the payment of dividends. Any of these factors, individually or in combination, could prevent us from being able to obtain the capital we require on terms that are acceptable to us, and the failure to obtain
necessary capital could materially adversely affect our future growth.

OUR ABILITY TO HARVEST TIMBER MAY BE SUBJECT TO LIMITATIONS WHICH COULD ADVERSELY AFFECT OUR
OPERATIONS

Weather conditions, timber growth cycles, access limitations, availability of contract loggers, and regulatory requirements associated with the
protection of wildlife and water resources may restrict harvesting of timberlands as may other factors, including damage by fire, insect infestation, disease, prolonged drought and other natural disasters. Although damage from such natural causes
usually is localized and affects only a limited percentage of the timber, there can be no assurance that any damage affecting our timberlands will in fact be so limited. As is common in the forest products industry, we do not maintain insurance
coverage with respect to damage to our timberlands.

Our revenues, net income and cash flow from our operations are dependent to a significant extent on the
pricing of our products and our continued ability to harvest timber at adequate levels. In addition, the terms of our long-term debt agreements limit our ability to fund dividends to stockholders by accelerating the harvest of significant amounts of
timber.

OUR TIMBERLANDS AND MANUFACTURING FACILITIES ARE SUBJECT TO FEDERAL AND STATE ENVIRONMENTAL REGULATIONS

We are subject to regulation under, among other laws, the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, the Comprehensive Environmental
Response Compensation and Liability Act of 1980, the National Environmental Policy Act, and the Endangered Species Act, as well as comparable state laws and regulations. Violations of various statutory and regulatory programs that apply to our
operations could result in civil penalties, remediation expenses, potential injunctions, cease and desist orders and criminal penalties.

We engage in the
following activities that are subject to regulation:



| |  | forestry activities, including harvesting, planting and road building, use and maintenance;
|- |  | -------------------------------------------------------------------------------------------



| |  | the generation of air emissions;
|- |  | --------------------------------



| |  | the discharge of industrial wastewater and storm water; and
|- |  | -----------------------------------------------------------



| |  | the generation and disposal of both hazardous and non-hazardous wastes.
|- |  | -----------------------------------------------------------------------

Laws and regulations protecting the environment have generally become more stringent in recent years and could become more stringent in the future. Some environmental statutes impose strict liability, rendering a
person liable for environmental damage without regard to the persons negligence or fault. These laws or future legislation or administrative or judicial action with respect to protection of the environment may adversely affect our business.

The Endangered Species Act and comparable state laws protect species threatened with possible extinction. A number of species on our timberlands have been
and in the future may be protected under these laws. Protection of threatened and endangered species may include restrictions on timber harvesting, road building and other forest practices on private, federal and state land containing the affected
species.

Some provisions of our certificate of incorporation may discourage a third party from seeking to gain control
of us. For example, the ownership limitations described in our certificate of incorporation could have the effect of delaying, deferring, or limiting a change of control in which holders of our common stock might receive a premium for their shares
over the then prevailing market price. The following is a summary of provisions of our certificate of incorporation that may have this effect.

##### Table of Contents

Ownership Limit.In order for us to maintain our qualification as a REIT, not more than 50% of the value of our outstanding shares of capital stock may be owned, directly or indirectly, by five or fewer individuals, as defined in the Internal
Revenue Code. For the purpose of preserving our REIT qualification, our certificate of incorporation prohibits ownership, either directly or under the applicable attribution rules of the Internal Revenue Code, of more than 5% of the lesser of the
total number of shares of our common stock outstanding or the value of the outstanding shares of our common stock by any stockholder other than by some designated persons agreed to by us or as set forth in our certificate of incorporation (the
Ownership Limit). The Ownership Limit may have the effect of discouraging an acquisition of control of us without the approval of our Board of Directors.

The Ownership Limit in our certificate of incorporation also restricts the transfer of our common stock. For example, any transfer of our equity is null and void if the transfer would:



| |  | result in any person owning, directly or indirectly, equity in excess of the Ownership Limit;
|- |  | ---------------------------------------------------------------------------------------------



| |  | result in our equity being owned, directly or indirectly, by fewer than 100 persons;
|- |  | ------------------------------------------------------------------------------------



| |  | result in us being closely held (as defined in the Internal Revenue Code);
|- |  | ----------------------------------------------------------------------------



| |  | result in us failing to qualify as a domestically controlled REIT (as defined in the Internal Revenue Code); or
|- |  | -----------------------------------------------------------------------------------------------------------------



| |  | otherwise cause us to fail to qualify as a REIT.
|- |  | ------------------------------------------------

Preferred Stock.Our certificate of incorporation authorizes our Board of Directors to issue up to 75 million shares of
preferred stock. Upon issuance, our Board of Directors will establish the preferences and rights for this preferred stock. These preferences and rights may include the right to elect additional directors. The issuance of preferred stock could have
the effect of delaying or preventing a change in control of us even if a change in control were in our stockholders best interests.

Section 203 of the Delaware General Corporation Law.Section 203 of the Delaware General Corporation Law generally prohibits us from
engaging in business transactions with a person or entity that owns 15% or more of our voting stock for a period of three years following the time such person or entity became an interested stockholder unless, prior to such time, our
Board of Directors approved either the business combination or the transaction which resulted in such person or entity becoming an interested stockholder. A business transaction may include mergers, asset sales and other transactions resulting in
financial benefit to the person or entity that owns 15% or more of our voting stock.

Tax Risks

IF WE FAIL TO QUALIFY AS A REIT, WE WOULD BE SUBJECT TO TAX AT CORPORATE RATES AND WOULD NOT BE ABLE TO DEDUCT DIVIDENDS TO STOCKHOLDERS WHEN COMPUTING OUR TAXABLE INCOME

If in any taxable year we fail to qualify as a REIT:



| |  | we would be subject to federal and state income tax on our taxable income at regular corporate rates;
|- |  | -----------------------------------------------------------------------------------------------------



| |  | we would not be allowed to deduct dividends to stockholders in computing our taxable income; and
|- |  | ------------------------------------------------------------------------------------------------



| |  | unless we were entitled to relief under the Internal Revenue Code, we would also be disqualified from treatment as a REIT for the four taxable years following the
year during which we lost qualification.
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If we fail to qualify as a REIT, we might need to borrow funds or liquidate some investments in
order to pay the additional tax liability. Accordingly, funds available for investment or dividends to our stockholders would be reduced for each of the years involved.

Qualification as a REIT involves the application of highly technical and complex provisions of the Internal Revenue Code to our operations and the determination of various factual matters and circumstances not
entirely within our control. There are only limited judicial or administrative interpretations of these provisions. Although we operate in a manner consistent with the REIT qualification rules, we cannot assure you that we are or will remain so
qualified.

In addition, federal and state tax laws are constantly under review by persons involved in the legislative process, the Internal Revenue
Service, the United States Department of the Treasury, and state taxing authorities. Changes to the tax law could

adversely affect our stockholders. We cannot predict with certainty whether, when, in what forms, or with what effective dates, the tax laws applicable to us
or our stockholders may be changed.

IF WE FAILED TO DISTRIBUTE THE EARNINGS AND PROFITS OF THE TIMBER COMPANY, WE WOULD BE SUBJECT TO ADVERSE TAX CONSEQUENCES

In connection with The Timber Companys October 6, 2001, merger with Plum Creek, we were required by January 31, 2002, to distribute the
earnings and profits acquired from the six entities that comprised The Timber Company. We believe that the accelerated payment of our fourth quarter dividend for 2001, which we paid on December 28, 2001, was sufficient to distribute these
earnings and profits. If we failed to distribute an amount equal to these earnings and profits, we might be subject to adverse tax consequences. We expect that, even if the earnings and profits were subsequently adjusted upward by the Internal
Revenue Service, the amount we distributed exceeded such earnings and profits. Nevertheless, such an adjustment may give rise to the imposition of the 4% excise tax on the excess income required to be distributed over the amounts treated as
distributed after application of the earnings and profits rule.

CERTAIN OF OUR BUSINESS ACTIVITIES ARE POTENTIALLY SUBJECT TO PROHIBITED TRANSACTIONS TAX OR
CORPORATE-LEVEL INCOME TAX

Under the Internal Revenue Code, REITs must generally engage in the ownership and management of income producing real estate.
For Plum Creek, this generally includes owning and managing a timberland portfolio for the production and sale of standing timber. Accordingly, the manufacture and sale by us of wood products, the harvesting and sale of logs, and the development
and/or sale of certain timberlands are conducted through one or more of our wholly-owned taxable REIT subsidiaries (TRSs) because such activities could generate non-qualifying REIT income and could constitute prohibited
transactions. Prohibited transactions are defined by the Internal Revenue Code to be sales or other dispositions of property to customers in the ordinary course of a trade or business. By conducting our business in this manner we believe that
we satisfy the REIT requirements of the Internal Revenue Code and are not subject to the 100% tax that could be imposed if a REIT were to conduct a prohibited transaction. We may not always be successful, however, in limiting such activities to our
TRSs. Therefore, we could be subject to the 100% prohibited transactions tax if such instances were to occur. The net income of our TRSs is subject to corporate-level income tax.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

We believe that our timberlands and manufacturing facilities are suitable and adequate for current
operations. The manufacturing facilities are owned and are maintained through on-going capital investments, regular maintenance and equipment upgrades. The majority of the manufacturing facilities are modern facilities. During 2006, our lumber,
plywood and MDF manufacturing facilities produced at planned capacity levels and there were no significant idle times at the facilities at any time during the year. See Item 1. Business for discussion of the location and description
of properties and encumbrances related to properties.

ITEM 3. LEGAL PROCEEDINGS

There is no individual pending or threatened litigation involving the company that we believe
would have a material adverse effect on the companys financial position, results of operations or liquidity. However, see Note 13 of the Notes to Financial Statements.

Merger. Although the companys stockholders did not separately approve the assumption of these stock options, the stockholders did approve each of The Timber Company Merger and the related merger agreement (and all of the transactions
contemplated by the merger agreement, including the companys assumption of the stock options). No additional Plum Creek stock options may be granted under the Georgia-Pacific long-term incentive plans.

ITEM 7. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Forward-Looking Statement

This Report contains forward-looking statements within the meaning of the Private Litigation Reform Act of 1995. Some of the forward-looking statements can
be identified by the use of forward-looking words such as believes, expects, may, will, should, seeks, approximately, intends, plans,
estimates, projects, strategy, or anticipates, or the negative of those words or other comparable terminology. Forward-looking statements involve inherent risks and uncertainties. A number of important
factors could cause actual results to differ materially from those described in the forward-looking statements, including those factors described in Risk Factors under Item 1A in this Form 10-K. Some factors include changes in
governmental, legislative and environmental restrictions, catastrophic losses from fires, floods, windstorms, earthquakes, volcanic eruptions, insect infestations or diseases, as well as changes in economic conditions and competition in our domestic
and export markets and other factors described from time to time in our filings with the Securities and Exchange Commission. In addition, factors that could cause our actual results to differ from those contemplated by our projected, forecasted,
estimated or budgeted results as reflected in forward-looking statements relating to our operations and business include, but are not limited to:



| |  | the failure to meet our expectations with respect to our likely future performance;
|- |  | -----------------------------------------------------------------------------------



| |  | an unanticipated reduction in the demand for timber products and/or an unanticipated increase in supply of timber products;
|- |  | ---------------------------------------------------------------------------------------------------------------------------



| |  | an unanticipated reduction in demand for higher and better use timberlands or non-strategic timberlands;
|- |  | --------------------------------------------------------------------------------------------------------



| |  | our failure to make strategic acquisitions or to integrate any such acquisitions effectively or, conversely, our failure to make strategic divestitures; and
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | our failure to qualify as a real estate investment trust, or REIT.
|- |  | ------------------------------------------------------------------

It is likely that if one or more of the risks materializes, or if one or more assumptions prove to be incorrect, the current expectations of Plum Creek and its management will not be realized. Forward-looking
statements speak only as of the date made, and neither Plum Creek nor its management undertakes any obligation to update or revise any forward-looking statements.

Overview

2006 OPERATING PERFORMANCE COMPARED TO 2005

Operating
income increased by $13 million to $461 million in 2006. This increase was due primarily to the one-time gain of $14 million in connection with the settlement of the Canadian Lumber dispute. (See Note 1 of the Notes to Financial Statements,
Other Operating Income)

Operating income in our Northern Resources Segment increased by $6 million to $105 million in 2006. This increase was
due primarily to $13 million of operating income associated with our November 2005 acquisition of 650,000 acres of timberlands in Michigan, offset in part by lower sawlog prices and higher per ton log and haul rates. Operating income in our Southern
Resources Segment decreased by $39 million, or 18%, to $178 million. This decrease was due primarily to a weaker product mix, lower sawlog prices and higher per ton log and haul rates. During 2005, we substantially completed the conversion of
numerous natural stands to plantations; and therefore, the percentage of large-diameter sawlogs harvested in 2006 decreased and the percentage of small-diameter sawlogs and pulpwood increased. Operating income decreased by $14 million as a result of

Operating income from our Real Estate Segment increased by $42 million, or 31%, to $178 million. This increase was due primarily to
our expanding real estate development business and selling a higher percentage of high-value properties and a lower percentage of low-value properties. During 2006, operating income associated with our real estate development business was $22
million compared to an operating loss of $7 million during 2005.

Operating income for our Manufactured Products Segment decreased by $7 million to $22 million. This decrease was due
primarily to lower lumber prices, higher plywood manufacturing costs and higher MDF raw material costs, offset in part by higher MDF prices.

Our operating
income in 2005 and 2006 has been significantly impacted by higher per ton log and haul rates. In our Northern Resources Segment, operating income was negatively impacted by $9 million in 2005 compared to 2004 and by an additional $8 million in 2006
compared to 2005. Additionally, in our Southern Resources Segment, operating income was negatively impacted by $10 million in 2005 compared to 2004 and by an additional $11 million in 2006 compared to 2005. The per ton increase in log and haul rates
is due primarily to higher fuel costs and longer hauling distances.

Our 2006 earnings were also impacted by higher interest expense. Interest expense
increased by $24 million, or 22%, to $133 million. This increase was due primarily to the issuance of $300 million senior notes due 2015 in connection with our acquisition of timberlands in Michigan for $345 million in November 2005 and our
repurchase of approximately 7.5 million shares of our common stock for $263 million during 2006.

KEY ECONOMIC FACTORS IMPACTING OUR BUSINESS

Our operating performance 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. During 2004 and 2005,
housing starts were 1.96 million and 2.07 million, respectively. We believe housing starts in 2004 and 2005 were at unsustainable levels due to low interest rates and speculative buying. Housing starts during 2006 decreased by 12% to
1.82 million starts and are expected to decline further in 2007. The further decline is due in part to higher interest rates, increased inventory of unsold homes and higher vacancy rates. Thirty-year fixed-rate interest rates increased from
5.9% during 2005 to 6.4% during 2006. At the end of 2006, there was over a six month supply of new homes for sale compared to a four and one-half month supply at the end of 2005.

During 2006, the demand for sawlogs weakened due to mill shutdowns and curtailments as a result of the slowdown in home construction and repair and remodeling activity. Repair and remodeling activities decreased
during 2006 and are expected to decline further during 2007 due to the decline in home sales and lower home price appreciation. The demand for sawlogs in 2007 is expected to remain weak until housing starts improve.

Currency exchange rates, tariffs and quotas, availability and cost of transportation, and the relative cost of manufacturing wood products impact imports of lumber and
other wood products into the United States. Canadian imports into the U.S. capture a significant share (approximately 33%) of the U.S. lumber market. A U.S. industry coalition believes the Canadian government, which owns most of the timberlands in
Canada, provides unfair subsidies by selling timber at below market prices. Prior to 2002, a trade agreement with Canada limited imports of lumber into the United States. Since May 2002, the U.S. has imposed duties on Canadian imports. Near the end
of 2006, the U.S. and Canadian governments reached a negotiated settlement. Under the terms of the settlement, approximately $4 billion of the previously collected $5 billion in duties were refunded to Canadian lumber producers. Furthermore, the
previously imposed duties were replaced with a system of tiered taxes and/or volume restrictions. It is too early to tell if the new system of excise taxes and volume restrictions will significantly impact lumber imports from Canada and therefore
favorably impact the demand for sawlogs.

REAL ESTATE SALES AND DEVELOPMENT PROPERTIES

We estimate that included in our 8.2 million acres of timberlands are approximately 1.7 million acres of higher and better use timberlands and about 400,000 acres of non-strategic timberlands. The higher and
better use timberlands are expected to be sold over the next 15 years for residential, recreational or conservation purposes. The non-strategic timberlands are expected to be sold over the next five years. Included within the 1.7 million acres
of higher and better use timberlands are approximately 225,000 acres that will be developed either internally or through joint ventures.

During 2006, we
sold approximately 60,000 acres of non-strategic timberlands and approximately 23,000 acres of higher and better use / recreational properties. We expect to significantly increase the number of acres we sell in 2007 in both of these categories.
Sales are expected to remain at this higher level in future years; however, the mix between non-strategic timberland

sales and higher and better use / recreational property sales could change. Furthermore, in 2007 our average price per acre for non-strategic timberlands is
likely to be lower than the price per acre we realized during 2006. Also, due to mix considerations, our average price per acre for higher and better use / recreational property sales are expected to be lower than the price per acre we realized
during 2006.

We continued to grow our land development business during 2006. We have identified 95,000 acres with an estimated 125 properties that we
expect to develop internally over the next 15 years. At December 31, 2006, we had 13 internal development properties entitled and an additional 32 in the planning process. Revenue from sales of development properties was $65 million during
2006, which included revenue of $43 million from one sale we had been working on for several years. We are continuing to build a portfolio of internal development projects we can bring to the market and expect to reach our level of sustained sales
either in the second-half of 2007 or 2008. Our development business is conducted through our wholly-owned taxable REIT subsidiaries.

Additionally, we have
identified 130,000 acres that we expect to develop through joint ventures. We have entered into six joint venture arrangements covering approximately 26,000 acres. We do not expect significant revenues from these joint venture arrangements during
2007. We are the minority partner in each of these joint ventures, and our involvement is limited to selling and/or contributing land and exercising certain protective rights. We expect to enter into additional joint venture arrangements during
2007.

HARVEST LEVELS

The volume of trees we harvest each year and the
percentage of sawlogs and pulpwood included in our annual harvest also impact our operating performance. During 2006, we harvested a total of 21.0 million tons compared to a total of 19.2 million tons during 2005. The 9% increase in
harvest levels is due primarily to our November 2005 acquisition of 650,000 acres of timberlands in Michigan and a temporary increase in harvest levels to capture favorable log prices, especially during the first-half of 2006. We expect harvest
levels during 2007 to range between 19.5 and 20.5 million tons. However, future harvest levels may vary from historic levels due to weak 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 accounting principles generally accepted in the United States of America. 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

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 contracts 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 Contracts.Pay-as-cut
contracts are agreements in which the buyer agrees to harvest all of the 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 contracts. In other cases, the buyer agrees to harvest only certain trees on a tract of land. Under pay-as-cut 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 contract is the total volume of wood removed multiplied by the unit price for each type of tree.

##### Table of Contents

(3) 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, 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.). 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.

Since 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. Finally, for our larger lump-sum contracts, which cover multiple tracts,
we adjust revenues at the end of each accounting period for any known trends in the tracts that have been completely harvested. For lump-sum contracts completed during the past twelve quarters, our largest quarterly adjustment to record the
difference between estimated lump-sum revenues and actual revenues has been $0.6 million.

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

Substantially all of our timber sales in the Northern Resources Segment are under delivered log sale agreements. In
our Southern Resources Segment, approximately one-third of our timber sales consists of either pay-as-cut contracts or lump-sum sales. Since under both pay-as-cut contracts and lump-sum sales the buyer is responsible for the logging and hauling
costs, the operating profit as a percentage of revenue is significantly higher in our Southern Resources Segment.

(4) Real Estate Sales.We estimate that included in the companys approximately 8.2 million acres of timberlands are about 1.7 million acres of higher and
better use timberlands, which are expected to be sold and/or developed over the next 15 years for residential, recreational or conservation purposes. In addition, the company has approximately 400,000 acres of non-strategic timberlands, which are
expected to be sold over the next five years. In the meantime, these timberlands continue to be used productively in our business of growing and selling timber. The timing of real estate sales is a function of many factors, including the
availability of government and not-for-profit funding, the general state of the economy, the ability to obtain entitlements, the plans of adjacent landowners, our expectation of future price appreciation and the timing of harvesting activities. As a
result, the timing of our real estate sales may materially impact our reported operating income and net income.

During 2006, the Real Estate Segment
reported an operating profit percentage of approximately 58%. We estimate our Real Estate Segments annual operating profit percentage could range from 35% to 70% of revenues. The 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 have an operating profit percentage of close to 100% because no book basis is allocated to this type of
revenue. 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.

##### Table of Contents

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 cash flows are discounted at the risk-free rates of interest. Future cash flow estimates are based on probability-weighted projections for a range of possible outcomes. 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.

We have grown substantially through acquisitions in recent years. 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 in a business combination 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 8.2 million acres of timberlands by
grouping them into eight geographic areas in the Northern Resources Segment and eight 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 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 2006, the above criteria were met by a number of our timberland properties, and we recognized impairment losses of $2 million. Similarly, we recognized
impairment losses of $1 million in 2005 and $21 million during 2004 in connection with timberlands held for sale (see Note 3 of the Notes to 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.

##### Table of Contents

In accordance with SFAS No. 144, an impairment loss is generally not recorded until management has concluded that it
is probable (i.e., likely) that timberlands will be sold within the next 12 months. For many properties that are currently being actively marketed, it is difficult to conclude whether they will be sold within one year and estimate the price.
Nevertheless, management performs a probability assessment for all properties that are being actively marketed and records an impairment loss (to the extent the propertys book basis exceeds its estimated fair value net of selling cost) in the
quarter in which management has concluded it is likely the property will be sold within 12 months based on its best estimate of fair value.

(3) Property, Plant and Equipment.The carrying value of Property, Plant and Equipment represents primarily the net book value of our ten
manufacturing facilities. Each manufacturing facility is tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable through future operations. The estimated future cash flows over the
remaining useful life of a manufacturing facility is highly subjective and is dependent upon estimates for future product pricing, raw material costs, volumes of product sold, and residual value of the facility. During the fourth quarter of 2004, we
recognized an impairment loss of $9 million in connection with one of our lumber mills due to a declining supply of logs. The availability of logs in close proximity to our mills has been declining and is expected to decline further in the future.
We currently estimate that the carrying value for our ten manufacturing facilities is recoverable through future operations and that our estimate of future cash flows is reasonable. However, if wood product prices were to remain weak at current
levels for an extended period of time, or if log or raw material availability declines more than expected, the company may be required to record an impairment loss for one or more of its manufacturing facilities in a future period.

DEPLETION

Depletion, or costs attributed to timber harvested, is recorded as trees
are harvested. Depletion rates for each region are adjusted at least annually. Depletion rates are computed by dividing (A) the sum of (1) the original cost of the timber less previously recorded depletion plus (2) estimated future
silviculture costs, including the impact of inflation, that are expected to be incurred over the next harvest cycle, by (B) the total timber volume that is estimated to be harvested over the harvest cycle. The harvest cycle can be as short as
20 years in the South to as long as 90 years in the North. The estimate of future silviculture costs is limited to the expenditures that are expected to impact growth rates over the harvest cycle. The depletion rate calculations do not
include an estimate for either future reforestation costs associated with a stands final harvest or future volume in connection with the replanting of a stand subsequent to its final harvest.

|E | Assumes future silviculture costs do not change.
|- | ------------------------------------------------

Significant estimates and judgments are required to determine both future silviculture costs and the volume of timber available for harvest over the harvest cycle. Some
of the factors impacting the estimates are changes in weather patterns, inflation rates, the cost of fertilizers and chemicals, the cost of capital, the actual and estimated increase in growth rates from fertilizer applications, the relative price
of sawlogs and pulpwood, the actual and expected real price appreciation of timber, the scientific advancement in seedling and growing technology, and changes in harvest cycles.

We have invested in technology that enables us to predict our current standing inventory of trees, future growth rates, and the benefits of scientific advancements in connection with seedlings, planting techniques and
fertilizer applications. Therefore, while estimates with respect to depletion computations will be revised at least annually, we do not expect the depletion rates will change materially from year to year.

DEFERRED INCOME TAXES

Plum Creek has elected to be taxed as a REIT under sections
856-860 of the United States Internal Revenue Code. A REIT is generally not subject to corporate-level income tax if it distributes 100% of its taxable income to shareholders and satisfies other organizational and operational requirements as set
forth in the Internal Revenue Code. If a company fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify
as a REIT for four subsequent taxable years.

As a consequence of the October 6, 2001 merger with The Timber Company, which involved merging a taxable entity into
a nontaxable entity, Plum Creek will generally be subject to corporate-level tax (built-in gains tax) if the company makes a taxable disposition of certain property acquired in the merger with The Timber Company within the ten-year period following
the merger date. The built-in gains tax applies to gains from such asset sales to the extent that the fair value of the property exceeds its tax basis at the merger date. Built-in gains tax is generally not payable on dispositions of property to the
extent the proceeds from such dispositions are reinvested in qualifying like-kind replacement property. The built-in gains tax does not apply to income generated from the harvesting and sale of timber.

In connection with our merger with The Timber Company, we wrote-off all of The Timber Companys deferred income tax liability related to timber and timberlands
except for $11 million. The $11 million deferred income tax liability relates to the book-tax basis difference of timber and timberlands that were expected to be sold, and subject to, the built-in gains tax during the ten-year period ending
October 6, 2011. During the period October 6, 2001 to December 31, 2006, the $11 million deferred income tax liability was reduced by $1 million due to the payment of tax in connection with sales of timberlands subject to the built-in
gains tax.

In accordance with Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes,we remeasure the amount of
deferred income taxes needed in connection with expected sales of timberlands subject to the built-in gains tax each quarterly reporting period. In 2005, we reduced the deferred tax liability to $5 million and correspondingly recorded a deferred tax
benefit of $5 million. Based on projected timberland sales subject to the built-in gains tax for the period December 31, 2006 to October 6, 2011, and our ability to successfully reinvest proceeds in like-kind properties, we estimate we
need a deferred tax liability of $5 million. As a result, no adjustment to the deferred tax liability associated with expected sales of timberlands subject to the built-in gains tax was made in 2006.

It is likely that actual timberland sales subject to the built-in gains tax over the ten-year period will be greater than, or less than, our current projection. An
adjustment to earnings will be required in the period in which it is determined that timberland sales subject to the built-in gains tax will be greater than, or less than, our current projection.

ACCOUNTING FOR SHARE-BASED COMPENSATION

Plum Creek has a stockholder approved Stock
Incentive Plan that provides for the award of non-qualified stock options, restricted stock and restricted stock units, value management awards and dividend equivalents. See Note 11 of the Notes to Financial Statements.

The company adopted Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS No. 123(R)) effective
January 1, 2006. See Note 1 of the Notes to Financial Statements. Grants of both value management awards and dividend equivalents represent awards that are classified and accounted for as liabilities under SFAS No. 123(R). As a result, the
expense recognized over the performance period for both value management awards and dividend equivalents will equal the fair value (i.e., cash value) of an award as of the last day of the performance period multiplied by the number of awards that
are earned. Furthermore, SFAS No. 123(R) requires the quarterly expense recognized during the performance period to be based on the fair value of value management awards and dividend equivalents as of the end of the most recent quarter. Prior
to the end of the performance period, compensation costs for value management awards and dividend equivalents are based on the awards most recent quarterly fair values and the number of months of service rendered during the performance period.

Fair values for value management awards and dividend equivalents are computed based on our historical relative total shareholder return compared to the
performance of peer groups consisting of forest products companies, the S&P 500 Index and the Morgan Stanley REIT Index over the same period (Peer Group). The simulated total shareholder return of the company and the Peer Groups is
computed using a Monte Carlo simulation. The key assumptions used in the simulation of the companys and the Peer Groups total shareholder return are volatility, beta (the measure of how Plum Creeks stock moves relative to the
market as a whole), risk-free interest rate, and expected dividend yield. Additionally, the fair value of dividend equivalents assumes that our current quarterly dividend of the companys common stock of $0.42 per share will remain constant
through the end of the performance period.

##### Table of Contents

The fair value liability for outstanding value management awards and dividend equivalents at December 31, 2006 was
$10 million, which is based on the current fair value of outstanding awards multiplied by the percentage of months worked during the performance period. The liability at December 31, 2006 could range between $7 million and $17 million based on
the possible fair value of all outstanding liability based awards. In accordance with SFAS No. 123(R), we could have a material adjustment to our share-based compensation liability to the extent there is a material change in the fair value of
our value management awards and dividend equivalents during the quarter.

PENSIONS

Plum Creek provides pension benefits under defined benefit pension plans that cover substantially all of our employees. See Note 10 of the Notes to Financial Statements. We maintain a qualified defined benefit pension
plan and two supplemental (non-qualified) defined benefit pension plans. Participants benefits generally vest after five years of service. The cash balance benefits for salaried employees is determined based primarily on certain percentages of
compensation, age, years of service and interest accrued based on the 30-year treasury bond rate. Furthermore, employees of the company on September 1, 2000, earn benefits based on the greater of the cash balance formula or a monthly pension
benefit that is principally based on the highest monthly average earnings during any consecutive sixty-month out of the last 120-month period and the number of years of service credit. The benefits to hourly employees are generally based on a fixed
amount per year of service.

Plum Creeks contributions to its qualified pension plan vary from year to year, but the company has made at least the
minimum contributions required by law in each year. Generally, we intend to fund our qualified pension plan annually by either the value of the benefits earned during the year or, if more, the amount such that the fair value of plan assets equals or
exceeds the actuarially computed accumulated benefit obligation (ABO, the approximate actuarially computed current pension obligation if the plan was discontinued). The company has the same funding policy for the non-qualified plan.
However, assets related to the non-qualified plans are held in a grantor trust and are subject to the claims of creditors.

The computation of the
companys benefit obligation, pension cost and accrued pension liability under accounting principles generally accepted in the United States of America requires us to make certain assumptions involving primarily the following (weighted-average
rates):



|                                                                    |  |      |   |  |

|A | The December 31, 2006, discount rate was determined by the resulting yield of a hypothetical bond
portfolio at December 31, 2006, matched to the expected benefit payments under the plans. Bonds selected for this portfolio had a Moodys or Standard & Poors credit rating of AA or better as of December 31,
2006.
|- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|B | The expected long-term rate of return on plan assets assumption is based on the current level of
expected returns on risk free investments (primarily government bonds), the historical level of the risk premium associated with the other asset classes in which the portfolio is invested and the expectations for future returns on each asset class.
The expected return for each asset class is weighted based on the target asset allocation to develop the expected long-term rate of return on plan assets assumption for the portfolio.
|- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|C | The assumed rate of increase of future compensation levels represents our long-term estimate of such
increases on the basis of the composition of plan participants, past results and market expectations.
|- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Other key assumptions used in the
estimate include primarily those underlying the mortality table, and expected long-term rates for inflation, retirement and withdrawals, all of which are based on plan experience and standard actuarial methods but which are nevertheless subject to
uncertainty.

It is likely that the actual return on plan assets and the outcome of other uncertain variables will differ from those
used in estimating our pension costs and pension obligation reflected in our consolidated financial statements and notes thereto. Furthermore, the company may, from time to time, adjust the asset allocation, which may have an impact on the long-term
rate of return on plan assets.

The following table summarizes key financial measures and sensitivities to changes in assumptions for theyears ended December 31(in millions):

|A | We adopted the recognition and disclosure provisions of SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement
Plans (SFAS No. 158) on December 31, 2006. Under SFAS No. 158, we are required to recognize the funded status for our defined benefit plans in our December 31, 2006, Consolidated Balance Sheet.
|- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Assuming an average long-term rate of return on plan assets of 7.75%, a weighted-average discount rate of 5.90% for 2007 and 6.20% for 2008
and beyond, and a 3.70% rate of increase in compensation levels, we project that our annual pension expense for 2007 and 2008 will be approximately $8 million each and for 2009 and 2010 will be $9 million each. Over the same time period, the annual
cash funding required under our present funding policy and current funding rules for the qualified pension plan is expected to be approximately $5 million annually through 2009 and $6 million in 2010. Given the well-funded nature of the plan, we
believe the Pension Protection Act of 2006 will not have a material affect on our funding requirements.

Off-Balance Sheet Arrangements, Contractual Obligations,
Contingent Liabilities and Commitments

The company has no off-balance sheet debt. Our consolidated financial statements reflect all of the operations and
assets and liabilities of the company. As of December 31, 2006, the company has entered into six joint venture agreements with land developers covering approximately 26,000 acres. We are the minority partner in each of these joint ventures, and
our involvement is limited to selling and/or contributing land and exercising certain protective rights. The company also has an insignificant equity investment in an unconsolidated entity. Otherwise, the company has no other relationships with
unconsolidated entities or financial partnership, such as entities referred to as structured finance or special purpose entities.

During the second quarter
of 2006, we entered into two treasury-lock arrangements to secure current long-term interest rates in connection with our issuance of $225 million of senior notes due 2015. See Note 6 of the Notes to Financial Statements. These transactions were
settled for a net gain of $0.9 million. In November 2006, the company entered into a purchase commitment to supply natural gas to our manufacturing facilities, which expires in March 2007. The contract, which is a derivative, was designated as a
normal purchase under the terms of SFAS No. 133, Accounting for Derivatives Instruments and Hedging Activities. As of December 31, 2006, the companys remaining purchase obligation under this contract was $0.8 million. The
company is not a party to any other derivative transactions.

|A | In addition to principal, long-term debt includes related interest obligations based on the coupon or
stated interest rate for our fixed rate debt of $114 million (Less than one year), $201 million (1-3 years), $154 million (3-5 years), and $144 million (More than 5 years). As we expect borrowings outstanding under our line of credit to vary, only
repayment of principal is included. Interest expense related to our line of credit was $10 million in 2006.
|- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|B | Purchase obligations are comprised primarily of $13 million for third-party logs for our plywood
and sawmill facilities, $5 million for contract services for freight and logging, $5 million for raw materials for our MDF facilities, $4 million for real estate commitments, and $3 million for reforestation and silviculture.
|- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|C | We have not included any amounts for our other long-term liabilities, as we cannot estimate when we will
be obligated to satisfy these liabilities. At December 31, 2006, other long-term liabilities include workers compensation of $9 million, deferred compensation obligations of $8 million, non-qualified pension obligations of $23 million
(including $3 million classified as a current liability), and qualified pension obligations of $11 million. We expect to fund approximately $3 million for workers compensation payments in 2007. We have made contributions to our qualified
pension plan such that the fair value of the pension plan assets at December 31, 2006, exceeds the actuarially computed accumulated benefit obligation. As a result of this funding level, there are no qualified pension funding obligations at
December 31, 2006. We have two grantor trusts, which hold assets associated with our deferred compensation obligations and non-qualified pension obligations. At December 31, 2006, the fair value of assets in one of our grantor trusts is
approximately equal to our deferred compensation obligation of $8 million. Additionally, at December 31, 2006, the fair value of assets in the other grantor trust and the actuarially computed accumulated benefit obligation for our non-qualified
pension plans was $19 million each. Assets in our grantor trusts have been reserved for the above obligations. However, grantor trust assets are subject to the claims of creditors in the event of bankruptcy. See Notes 8 and 10 of the Notes to
Financial Statements.

Events and Trends Affecting Operating Results

HARVEST PLANS

We determine our annual roundwood (sawlogs and pulpwood, including stumpage sales) harvesting plans based on a number of factors. At
the stand level, ranging in size from 10 to 200 acres, we consider the age, size, density, health and economic maturity of the timber. A stand is a contiguous block of trees of a similar age, species mix and silvicultural regime. At the forest
level, ranging in size from 100,000 to almost 1,000,000 acres, we consider the long-term sustainability and environmental impact of certain levels of harvesting, certain external conditions such as supply agreements, and the level of demand for wood
within the region. A forest is a broad administrative unit, made up of a large number of stands. Harvest scheduling is the technical approach using computer modeling that considers all of the above factors along with forest growth rates and
financial assumptions to project future harvest plans for a number of years forward.

Our actual harvest levels may vary from planned levels due to log
demand, sales prices, the availability of timber from other sources, the level of timberland sales and acquisitions, the availability of legal access, abnormal weather conditions, fires and other factors outside of our control. We believe that our
harvest plans are sufficiently flexible to permit modification in response to short-term fluctuations in the markets for logs. Furthermore, future harvest levels will be impacted by both our planned sales of non-strategic and higher and better use
timberlands. The impact will depend on the level and extent we are able to reinvest proceeds in productive timberlands and the stocking levels and age class distribution of any newly acquired timberlands.

Harvest levels in the Northern Resources Segment were 6.8 million tons (60% sawlogs and 40% pulpwood) during 2006
and 5.4 million tons (66% sawlogs and 34% pulpwood) during 2005. Our harvest levels and change in mix were due primarily to our acquisition of 650,000 acres of timberland in Michigan during the fourth quarter of 2005. Excluding the Michigan
timberlands, our harvest levels were 5.9 million tons (65% sawlogs and 35% pulpwood) during 2006. We expect harvest levels in the Northern Resources Segment in 2007 to decrease between 7% and 13% from 2006; however, the log mix is expected to
remain consistent with 2006.

Harvest levels in the Southern Resources Segment were 14.1 million tons (47% sawlogs and 53% pulpwood) during 2006 and
13.8 million tons (51% sawlogs and 49% pulpwood) during 2005. In 2007, we expect harvest levels will be flat to 4% lower from 2006 and the log mix in the Southern Resources Segment is expected to remain consistent with 2006.

U.S.CANADA SOFTWOOD LUMBER AGREEMENT

Historically, Canada has been a
significant source of lumber for the U.S. market, particularly in the new home construction market. A trade agreement concerning lumber imports between the U.S. and Canada expired in March 2001. Soon thereafter, a U.S. industry coalition, of which
Plum Creek is a member, submitted anti-dumping and countervailing duty petitions to the International Trade Commission and the U.S. Department of Commerce alleging that Canadian lumber exports to the U.S. were unfairly subsidized and that lumber
from Canada was being dumped into the U.S. market. In response to these petitions, the U.S. Department of Commerce imposed both countervailing and anti-dumping duties. Canada appealed the imposition of these duties to both NAFTA and the WTO.

On October 13, 2006, a definitive agreement was signed establishing a system of tiered taxes and/or volume restrictions that will be in effect for a
period of seven years. Generally, the agreement provides that no import restrictions would be imposed on Canadian lumber shipments to the U.S. when the published composite price for lumber is higher than $355 (per thousand board feet). Below that
level, a tiered export tax would be triggered. The impact of the taxes could be mitigated by fluctuations in the rate of exchange between U.S. and Canadian dollars.

Notwithstanding the signing of a definitive agreement between the U.S. and Canadian governments, there can be no assurance that the agreement will effectively create a fair trade environment. Therefore, downward pressure on domestic timber
and lumber prices caused by Canadian imports could continue or increase.

COMPARABILITY OF FINANCIAL STATEMENT PERIODS

Acquisitions and Divestitures.We have pursued and
expect to continue to pursue both the acquisition and divestiture of timberlands to increase the value of our assets. During 2006, we acquired 98,000 acres of timberlands, located primarily in Oregon. During 2005, we acquired 754,000 acres of
timberlands, located in Northern Michigan, Arkansas and Florida. During 2004, we acquired 78,000 acres of timberlands located in Arkansas and Maine. We sold approximately 112,000 acres of timberlands in 2006, 232,000 acres in 2005, and 377,000 acres
in 2004. As a result of these timberland acquisitions and dispositions, our ownership was 8.2 million acres at December 31, 2006, 8.2 million acres at December 31, 2005, and 7.8 million acres at December 31, 2004.
Accordingly, the comparability of periods covered by the companys financial statements is, and in the future may be, affected by the impact of timberland acquisitions and divestitures.

2006 COMPARED TO 2005

Northern Resources Segment.Revenues increased by $66 million, or 19%, to $413 million in 2006. Excluding revenues
associated with our November 2005 acquisition of 650,000 acres of timberlands in Michigan (Michigan acquisition), revenues increased by $21 million, or 6%, to $364 million. This increase of $21 million was due primarily to higher harvest
levels ($37 million), offset in part by lower softwood sawlog prices ($6 million) and a weaker product mix from log sales ($5 million).

Harvest levels
increased by approximately 11% over the prior years harvest levels of 5.4 million tons due primarily to a temporary increase in harvest levels to take advantage of favorable log prices, especially during the first half of 2006. Softwood
sawlog prices during 2006 were 2% lower than during 2005; however, softwood sawlog prices during the fourth quarter of 2006 were 9% lower than during the same period in the prior year. The lower prices are primarily due to mill curtailments as a
result of weak lumber and plywood prices and the significant decline in housing starts. The weaker product mix (higher percentage of pulpwood sales and lower percentage of sawlog sales) is primarily due to the temporary increase in the harvesting of
hardwood pulpwood stands to take advantage of favorable log prices.

Excluding the impact of our Michigan acquisition, operating income was 25% of its
revenues for 2006, and 29% for 2005. This decrease was due primarily to higher per ton log and haul rates and lower softwood sawlog prices. Segment costs and expenses increased by $60 million, or 24%, to $308 million. Excluding costs and
expenses associated with our Michigan acquisition, costs and expenses increased by $27 million, or 11%, to $272 million. This increase of $27 million was due primarily to higher log and haul and depletion cost ($19 million) as a result of higher
harvest levels and higher per ton log and haul rates ($8 million). Log and haul rates increased by approximately 4% due to higher fuel costs and longer hauling distances.

Southern Resources Segment.Revenues decreased by $22 million, or 4%, to $479 million in 2006. This
decrease was due primarily to a weaker product mix from log sales ($14 million) and lower sawlog prices ($11 million).

During 2005, we substantially
completed the conversion of numerous natural stands to plantations in order to improve growth rates. As a result of this conversion, our product mix has changed whereby the percentage of large-diameter sawlogs harvested during 2006 has decreased and
the percentage of small-diameter sawlogs and pulpwood harvested has increased. Sawlog prices during 2006 were 3% lower than during 2005; however, sawlog prices during the fourth quarter of 2006 were 10% lower than during the same period in the prior
year. The lower prices are primarily due to mill curtailments as a result of weak lumber and plywood prices and the significant decline in housing starts.

Southern Resources Segment operating income was 37% of its revenues for 2006, and 43% for 2005. This decrease was due primarily to a lower percentage of high-value sawlogs in the sales mix, lower sawlog prices, and higher per ton log and
haul rates. Segment costs and expenses increased by $17 million, or 6%, to $301 million in 2006. This increase was due primarily to higher log and haul cost per ton ($11 million). Log and haul rates increased by approximately 7% due to
higher fuel costs and longer hauling distances.

Revenues increased by $16 million to $308 million in 2006. This increase is due primarily to the sale of
development properties ($62 million), the timing and location of sales of higher and better use properties ($34 million) and conservation properties ($15 million), offset in part by a decrease in the sales of small non-strategic properties ($64
million) and no large, non-strategic timberland sales during 2006 ($31 million). 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 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. Development properties revenue increased in 2006 due
primarily to the sale of a large development project for proceeds of $43 million and the continued expansion of our real estate development business. This large development, which the company has been working on for several years, consisted of
approximately 1,900 acres of land in King County, Washington. (See Part I, Item 1. Business, Real Estate Segment for a summary of internal development properties and joint venture arrangements.)

Average price per acre for small non-strategic land sales was $1,585 during 2006 compared to $1,075 per acre during 2005. Compared to prices realized during 2006, the
majority of our remaining small non-strategic acres will likely have a lower price per acre. Average price per acre for higher and better use / recreational land sales was $4,070 during 2006 compared to $2,814 per acre during 2005. Due to increased
competition in several of our markets with the highest per acre prices for our higher and better use / recreational properties, we may shift our sales mix to regions that tend to have lower per acre prices for our higher and better use /
recreational properties. As a result, during 2007, we expect that our higher and better use / recreational properties will have a lower average price per acre. Each year we adjust our sales mix to capture value in the strongest markets.

The company employs an ongoing process designed to identify the long-term best use for each of its properties to guide the investment and management decisions on each
property. Currently, our 8.2 million acres includes 6.1 million acres of core timberlands, approximately 400,000 acres of timberlands considered to be non-strategic, and 1.7 million acres of timberlands with higher value for uses
other than growing timber. The non-strategic timberlands generally consist of small tracts and are expected to be sold over the next five years. The 1.7 million acres with higher value are further segmented into three categories: conservation
(500,000 acres); recreation and higher and better use properties (1,000,000 acres); and those properties we expect to develop (225,000 acres) through a wholly-owned taxable REIT subsidiary. The higher value properties, located throughout our
ownership, may be sold over approximately the next 15 years. The companys evaluation of the best economic use and future plans for its timberlands will change as markets for timber and alternative land uses evolve. As these changes occur,
additional core timberlands may be categorized as conservation, higher and better use, or development properties. Until these properties are sold, they will continue to be used productively in our business of growing and selling timber. We expect
revenues from real estate sales during 2007 to range between $330 million and $350 million from the sale of 150,000 to 190,000 acres. We estimate these sales will consist of 80,000 to 100,000 acres of non-strategic acres, 4,000 to 8,000
acres of development and joint venture acres and the remainder from the sales of higher and better use and conservation acres.

The Real Estate Segment
operating income as a percent of revenue was 58% for the period ended December 31, 2006, compared to 47% for the same period in 2005. This increase was due primarily to selling a greater percentage of lower value timberlands during 2005,
including 40,000 acres of large, non-strategic timberlands that were sold for a nominal gain. Real Estate Segment costs and expenses decreased by $26 million to $130 million in 2006. This decrease was due primarily to

selling fewer acres during 2006 ($58 million), offset in part by higher costs associated with our development business ($34 million). Costs associated with
our development business were $44 million for 2006 compared to $10 million in 2005, with approximately half of the development business costs in 2006 associated with the large project sold in King County, Washington. The remainder of the increase in
development costs was due to higher staffing levels, basis and selling costs for lot sales, and investigatory and feasibility costs in connection with the expansion of this business.

Manufactured Products Segment.Revenues decreased by $11 million, or 2%, to $493 million in 2006. This
decrease was due primarily to lower lumber prices ($4 million), lower lumber sales volume ($16 million), and lower plywood sales volume ($10 million), offset in part by higher MDF prices ($13 million) and higher MDF sales volume ($3
million). Lumber sales volume decreased by 7% due primarily to production curtailments as a result of a declining log supply and weak lumber prices. Lumber prices for 2006 were 5% lower than during 2005; however, lumber prices during the fourth
quarter of 2006 were 11% lower than during the same period in the prior year due to the sharp decline in housing starts. Housing starts in the U.S. during 2006 were 12% lower compared to 2005.

Plywood sales volume decreased by 7% due primarily to a declining supply of high-grade plywood logs in the region and increased competition from commodity plywood mills.
Plywood prices for 2006 were slightly higher than 2005; however, plywood prices during the fourth quarter of 2006 were 8% lower than during the fourth quarter of 2005. This price decline was due primarily to increased competition from commodity
plywood producers which have targeted sales to industrial customers as a result of the slow down in home construction. MDF prices increased an average of 9% for all of 2006 due primarily to a mix shift to higher value products and supply constraints
due to recent North America mill closures.

Manufactured Products Segment operating income was 5% of its revenues for 2006 and 6% for 2005. Manufactured
Products Segment costs and expenses decreased by $4 million, or 1%, to $471 million in 2006. This decrease of $4 million was due primarily to lower lumber sales volume ($12 million) and lower plywood sales volume ($9 million), offset in part by
higher plywood manufacturing costs ($8 million) and higher MDF raw material costs ($9 million). Plywood manufacturing costs increased due primarily to the increased costs associated with manufacturing higher value products. MDF raw material costs
increased due primarily to higher resin (due to higher energy costs) and wood fiber (due to regional fiber shortage) costs.

Other Costs and Eliminations.Other Costs and Eliminations (which consists of corporate overhead and intercompany profit elimination) decreased operating income by
$53 million in 2006, compared to a decrease of $48 million in 2005. This increase of $5 million was due primarily to increased costs associated with information technology, strategic business development, and financial and tax reporting.
Other Costs and Eliminations increased by 10% during 2006 and are expected to increase by another 10% in 2007 for similar reasons.

Gain from Canadian Lumber Settlement.In 2006, a definitive agreement was signed between the U.S. and Canadian governments to settle the long-standing
dispute over Canadian lumber imports. Under the terms of the agreement, approximately $500 million of deposits collected by the U.S. was paid to members of the U.S. industry coalition. As a member of the coalition, we received a pro rata share of
these funds totaling $14 million ($13 million, net of tax).

Interest Expense, net.Interest expense (net of interest income) increased $24 million, or 22%, to $133 million in 2006. This increase was due primarily to the issuance of $300 million of senior notes in connection with our
November 2005 Michigan timberland acquisition and our repurchase of approximately 7.5 million shares of common stock for $263 million in 2006. The share repurchase was funded by using a combination of cash and debt financing.

Provision for Income Taxes.The provision for income taxes
was $13 million for 2006 compared to $8 million for 2005. This change of $5 million is due primarily to a remeasurement of our Deferred Tax Liability in 2005, which reduced tax expense for 2005 by $5 million. This remeasurement was related to
projected sales of timberlands that are subject to built-in gains tax during the ten-year period ending October 6, 2011, that were acquired in connection with our merger with The Timber Company.

In addition to corporate-level income tax on certain non-REIT activities conducted through various wholly-owned taxable REIT subsidiaries, the company is subject to
built-in gains tax on certain property dispositions as a consequence of our October 6, 2001 merger with The Timber Company. Our merger with The Timber Company involved merging a taxable entity into a nontaxable entity, and as a result, Plum
Creek will generally be subject to corporate-level income tax (built-in gains tax) if the company makes a taxable disposition of certain property acquired in the merger within the ten-year period following the merger date. However, the tax is
generally not payable to the extent proceeds from such dispositions are reinvested in qualifying like-kind replacement property.

##### Table of Contents

In connection with our merger with The Timber Company, we wrote-off all of The Timber Companys deferred income tax
liability related to timber and timberlands except for $11 million. The $11 million deferred income tax liability relates to the book-tax basis difference of timber and timberlands that were expected to be sold, and subject to, the built-in gains
tax during the ten-year period ending October 6, 2011. During the period October 6, 2001 to December 31, 2006, the $11 million deferred income tax liability was reduced by $1 million due to the payment of tax in connection with sales
of timberlands subject to the built-in gains tax.

In accordance with Statement of Financial Accounting Standards No. 109, Accounting for Income
Taxes,we remeasure the amount of deferred income taxes needed in connection with expected sales of timberlands subject to the built-in gains tax each quarterly reporting period. In 2005, we reduced our deferred tax liability associated with
timber and timberlands by $5 million and correspondingly recorded a deferred tax benefit of $5 million. Based on projected timberland sales subject to the built-in gains tax for the period December 31, 2006 to October 6, 2011, and our
ability to successfully reinvest proceeds in like-kind properties, we estimate we need a deferred tax liability of approximately $5 million. As a result, no adjustment to the deferred tax liability associated with built-in gains tax was made in
2006.

2005 COMPARED TO 2004

Northern Resources Segment.Revenues increased by $22 million, or 7%, to $347 million in 2005. This increase was due primarily to higher harvest volume ($12 million) and
higher product prices ($11 million). The increase in volume is due primarily to harvesting on timberlands acquired during the past several years, stronger log demand due to new mills, and an increase of harvest levels in certain markets to take
advantage of favorable log prices. Revenues in 2005 included $4 million from the harvesting of 85,000 tons associated with our acquisition of 650,000 acres of timberlands in Michigan during November of 2005.

Sawlog prices increased by 3% ($8 million) due primarily to higher demand for logs as a result of increased lumber production and a limited supply of logs. Pulpwood
prices increased by 8% ($5 million) due primarily to low log inventories.

Northern Resources Segment operating income was 29% of its revenues for 2005 and
30% for 2004. Segment costs and expenses increased by $20 million, or 9%, to $248 million in 2005. This increase was primarily due to higher per ton log and haul rates ($12 million) and higher harvest volume. Log and haul cost on a per ton basis
increased by 7% due primarily to higher fuel costs. Segment expenses in 2005 included $3 million as a result of our harvesting on recently acquired timberlands in Michigan.

Southern Resources Segment.Revenues increased by $42 million, or 9%, to $501 million in 2005. This
increase was due primarily to a higher percentage of delivered log sales compared to sales of standing timber ($19 million), higher harvest volume ($11 million) and higher softwood sawlog prices ($7 million).

Revenues increased $19 million due to the companys increased percentage of delivered log sales. A portion of the increase in delivered log sales is by way of
decreasing the percentage of standing timber sales. Under its delivered log sale agreements, the company is responsible for log and haul costs. When standing timber is sold, the buyer incurs the log and haul costs. The company sells logs on a
delivered basis when, in managements judgment, log merchandising efforts will yield a premium over selling stumpage. While revenues are higher when the company is responsible for the logging and hauling of timber, a large portion of that
increase in revenue is to cover the related increase in cost of sales. As a result, on delivered log sales the company realizes lower operating income as a percentage of revenue, even though operating income is generally improved.

Harvest volume increased due to favorable harvesting conditions during most of 2005 and a planned increase in harvest levels. The planned increase in harvest levels is
the result of an increased percentage of maturing timber on our southern timberlands.

Softwood sawlog prices increased temporarily during the first half of
2005 due primarily to a weather-related shortage of logs. Several of our customers had low log inventories at the end of 2004 due to wet weather during the second half of 2004, and as a result, offered higher prices in order to rebuild log decks.

Southern Resources Segment operating income was 43% of its revenues for 2005 and 44% for 2004. Southern Resources Segment costs and expenses increased by
$28 million, or 11%, to $284 million in 2005. This increase was due primarily to an increase in log and haul costs as a result of a higher percentage of delivered log sales compared to sales of standing timber, increased harvesting volume,
and higher fuel costs. The per ton rate increase for log and haul costs, which increased costs and expenses by $11 million, was due primarily to higher fuel costs.

In 2005, approximately 350,000 acres of our timberlands in Mississippi were impacted by severe winds from Hurricane
Katrina. As a result, we recorded a $2 million loss in 2005, which represents the book basis for approximately 600,000 tons of timber that was destroyed. Following Hurricane Katrina, we began salvaging timber that was blown down but not destroyed.
For 2005, operating income was reduced by $1 million due to higher logging costs from our salvage operations.

Revenues decreased by $11 million to $292 million in 2005. Excluding revenues from the large, non-strategic
timberland sales, revenues increased $91 million to $261 million for 2005, compared to $170 million for 2004. This increase is due primarily to an increase in land sales activity as the company executes its strategy of selling non-strategic
timberlands. Large, non-strategic timberland sales excluded, the sales of our conservation and small non-strategic timberlands accounted for approximately 90% of the acres sold during 2005 compared to 82% of the acres sold during 2004. Higher and
better use timberland sales represented approximately 10% of the acres sold during 2005 compared to 18% of the acres sold during 2004.

Real Estate Segment
operating income was 47% of its revenues for 2005, compared to 49% for 2004. Real Estate Segment costs and expenses increased by $2 million to $156 million in 2005. This increase was due primarily to an increase in land sales activity associated
with small parcels of non-strategic timberlands ($28 million, primarily land basis) and an increase in costs associated with development activities ($7 million), offset in part by a decrease in large, non-strategic timberland sales ($34 million,
primarily land basis). Costs associated with our real estate development activities increased to $10 million in 2005 compared to $3 million in 2004 due primarily to new costs (e.g. investigatory, appraisals, feasibility studies, environmental and
engineering studies, market analysis) associated with our expanding real estate development business.

Manufactured Products Segment.Revenues decreased by $14 million, or 3%, to $504 million in 2005. This decrease was due primarily to lower lumber prices ($11 million),
lower plywood prices ($9 million), offset in part by higher MDF prices ($10 million). Despite the highest level of U.S. housing starts since 1972 (U.S. housing starts during 2005 were 5.6% higher than housing starts during 2004), lumber prices
decreased by 7% due primarily to increased lumber production and imports. U.S. lumber production during the first eleven months of 2005 was 4% higher than the same period in 2004 due to start-up of new mills and capacity expansions at existing
mills. Furthermore, lumber imports from Canada during the first eleven months of 2005 increased by 2% over the same period in 2004, and offshore imports (Europe and Latin America) increased by 28%, due primarily to the strength of the U.S. economy
and weak foreign markets.

Plywood prices decreased by 7% due primarily to the increase in North America structural panels (plywood and oriented strand
board) production capacity and offshore imports. During 2005, North America structural panel production capacity has increased by approximately one billion square feet, or approximately 3% of the annual U.S. structural panel consumption. During
2005, offshore imports (primarily Latin America) increased 32% over 2004 amounts.

MDF prices increased 6% due primarily to improved demand and a richer
production mix. MDF demand has increased due to strong housing starts and improved repair and remodeling markets. During the first half of 2004, we resolved all of our start-up issues associated with our new MDF thin-board line and, as a result,
have increased the percentage of higher-margin products we produce.

Manufactured Products Segment operating income was 6% of its revenues for 2005 and 11%
for 2004. This decrease was due primarily to lower lumber and plywood prices and higher energy and raw material costs. Manufactured Products Segment

costs and expenses increased by $13 million, or 3%, to $475 million in 2005. This increase was due primarily to higher log costs and higher energy
prices. Log costs have increased due primarily to a declining supply of logs in Montana and favorable lumber and plywood prices. Energy costs, including the impact on resin prices, have increased by $5 million over the prior year.

Other Costs and Eliminations.Other Costs and Eliminations
(which consists of corporate overhead and intercompany profit elimination) decreased operating income by $48 million in 2005, compared to a decrease of $42 million in 2004. This increase of $6 million was due primarily to higher corporate
overhead associated with accounting and timber and timberland systems, and corporate compliance.

Other
Operating Income (Expense), net.During 2004, we sold our working interest in our coalbed methane gas joint operating agreement to Geomet, Inc. for $27 million and recorded a gain of
$5 million.

Interest Expense, net.Net
interest expense decreased by $2 million to $109 million for 2005. This decrease was due primarily to the replacement of high interest rate debt with lower interest rate debt.

Provision for Income Taxes.The provision for income taxes was $8 million for 2005 compared to $27
million for 2004. This decrease of $19 million is due primarily to a $27 million decline in the operating income of the Manufacturing Products Segment (resulting in a lower tax expense of $11 million), a $5 million remeasurement of our Deferred Tax
Liability, and the $5 million gain we recognized during the second quarter of 2004 from the sale of our coalbed methane gas working interest (resulting in a higher tax expense in the prior year of $2 million). See Note 4 of the Notes to Financial
Statements for further discussion regarding the remeasurement of our Deferred Tax Liability.

Gain on
Sale of Properties, net of tax.In December 2004, the company sold certain subsurface property rights (primarily coal reserves, excluding coalbed methane, oil and gas reserves) in Buchanan
County, Virginia. The net gain, after reducing the proceeds for applicable book basis and income taxes, was $23 million. During the first quarter of 2005, the company sold its remaining coal reserves for a total gain of $20 million, net of
selling costs and applicable income taxes. The company also sold other industrial mineral assets during the fourth quarter of 2005 for a total gain of $3 million, net of tax.

Cash Flows from Operating Activities.Net cash provided by operating activities for the year ended December 31, 2006 totaled $556 million, compared to $516 million in 2005. The increase of $40 million was due primarily to a $65
million decrease in working capital, primarily as a result of a $51 million positive change related to the timing of when proceeds from a like-kind exchange trust are either reinvested in replacement property (primarily timberlands) or distributed
to the company. Proceeds associated with a forward like-kind exchange are either reinvested in like-kind property within 180-days, or if the

exchange is not successful, are distributed to the company at the end of either the 45-day identification period or the 180-day reinvestment period. During
2006, we received proceeds from an unsuccessful like-kind exchange while during 2005 we had numerous real estate sales in which the proceeds were held in a like-kind exchange trust as of December 31, 2005.

Net cash provided by operating activities for the year ended December 31, 2005 totaled $516 million, compared to $582 million in 2004. The decrease of $66
million was due primarily to a $27 million decrease in operating income from our manufacturing facilities and a $24 million increase in working capital. The increase in working capital was due primarily to an increase in like-kind exchange proceeds
held in escrow.

Debt Financing.In April
2006, the company filed with the Securities and Exchange Commission a shelf registration statement under which Plum Creek Timber Company, Inc., from time to time, may offer and sell any combination of preferred stock, common stock, depositary
shares, warrants and guarantees, and under which Plum Creek Timberlands, L.P., the companys wholly-owned operating partnership, may from time to time, offer and sell debt securities. The shelf registration statement expires on April 25,
2009.

On May 2, 2006, Plum Creek Timberlands, L.P. issued off the shelf registration statement $225 million aggregate principal amount of its senior
notes with a coupon rate of 5.875%, at a market price of 96.686% of the principal amount. The notes mature in 2015 and are fully and unconditionally guaranteed by Plum Creek Timber Company, Inc. The net proceeds of $216 million were used primarily
to repay outstanding debt maturing during 2006.

On June 29, 2006, the company terminated its previous $650 million revolving line of credit maturing
in January 2009 and entered into a new $750 million revolving line of credit agreement that matures in June 2011. The revolving line of credit may be increased to $1 billion subject to certain terms and conditions. As of December 31, 2006, the
weighted-average interest rate for the borrowings on the line of credit was 5.79%. The interest rate on the line of credit is based on LIBOR plus 0.425%. This rate can range from LIBOR plus 0.27% to LIBOR plus 1% depending on our debt ratings.
Subject to customary covenants, the line of credit allows for borrowings from time to time up to $750 million, including up to $100 million of standby letters of credit. Borrowings on the line of credit fluctuate daily based on cash needs. As of
December 31, 2006, we had $581 million of borrowings and $5 million of standby letters of credit outstanding; $164 million remained available for borrowing under our line of credit. As of January 5, 2007, $243 million of the
borrowings under our line of credit was repaid.

In November of 2005, Plum Creek Timberlands, L.P. issued $300 million aggregate principal notes with a
coupon rate of 5.875% at a market price of 99.731% of the principal amount. The notes, issued under a previous shelf registration statement, mature in 2015. The net proceeds of $297 million were used primarily to acquire 650,000 acres of timberlands
in Michigan, valued at $345 million. The transaction was also by funded by $87 million of like-kind exchange funds.

The companys borrowing agreements
contain various restrictive covenants, including limitations on harvest levels, sales of assets, the incurrence of indebtedness and making restricted payments (such as payments of cash dividends or stock repurchases). The borrowing agreements limit
our ability to make restricted payments based on available cash, which is generally our net income (excluding gains on the sale of capital assets) after adjusting for non-cash charges (such as depreciation and depletion), changes in various
reserves, less capital expenditures and principal payments on indebtedness that are not financed. Additionally, the amount of available cash may be increased by the amount of proceeds from the sale of higher and better use properties and, under
certain circumstances, by 50% of the amount of net proceeds from the sale of other assets. Furthermore, our line of credit requires that we maintain certain interest coverage and maximum leverage ratios. The company was in compliance with all of our
borrowing agreement covenants as of December 31, 2006.

The companys financial policy is to maintain a balance sheet that provides the financial
flexibility to pursue our strategic objectives. In order to maintain this financial flexibility, the companys objective is to maintain its investment grade credit rating. This is reflected in our moderate use of debt, good access to credit
markets and no material covenant restrictions in our debt agreements that would prevent us from prudently using debt capital.

Capital Expenditures.Capital expenditures, excluding the acquisition of timberlands, for 2006 were $92 million (including $6 million in real estate development
expenditures) compared to $89 million in 2005 and $70 million for 2004. During 2006, Plum Creek acquired approximately 98,000 acres of timberlands located primarily in Oregon for $111 million with funds from tax-deferred exchange
transactions and from use of our line of credit. During 2005, Plum Creek acquired approximately 754,000 acres of timberlands located in Northern Michigan, Arkansas and Florida for $501 million with funds from

tax-deferred exchange transactions, debt and funds from operations. During 2004, Plum Creek acquired approximately 78,000 acres of timberlands located
primarily in Arkansas and Maine for $66 million with funds from operations and funds from tax-deferred exchange transactions.

Planned capital
expenditures for 2007, excluding the acquisition of timberlands, are expected to range between $95 million and $105 million and include approximately $65 million for our timberlands, $15 million for real estate development
investments, $12 million for our manufacturing facilities, and $10 million for investments in information technology to support growth in our Real Estate Segment. The timberland expenditures are primarily for reforestation and other
expenditures associated with the planting and growing of trees. Approximately 50% of planned capital expenditures are discretionary in 2007. Discretionary expenditures consist primarily of silviculture, land development, and information technology
investments. Other capital expenditures consist primarily of reforestation and projects at our manufacturing facilities to sustain operating activities and improve safety. Included within the planned capital expenditures for our manufacturing
facilities for 2007 is approximately an $8 million investment to expand our bio-filter emissions control equipment at our MDF facilities to comply with stricter environmental standards that become effective October 1, 2008.

Equity.On February 6, 2007, our Board of Directors
declared a dividend of $0.42 per share, or approximately $74 million, which will be paid on March 2, 2007, to stockholders of record on February 16, 2007. Future dividends will be determined by our Board of Directors, in its sole
discretion, based on consideration of a number of factors including, but not limited to, our results of operations, cash flow and capital requirements, economic conditions, tax considerations, debt covenant restrictions that may impose limitations
on the companys ability to make cash payments, borrowing capacity, changes in the prices of and demand for Plum Creeks products, and changes in our ability to sell timberlands at attractive prices. Other factors that our Board of
Directors considers include the appropriate timing of timber harvests, acquisition and divestiture opportunities, stock repurchases, debt repayment and other means by which the company could deliver value to its stockholders.

In October 2002, the Board of Directors authorized a $200 million share repurchase program. In June 2006, the Board of Directors authorized an additional $200 million to
be used for the share repurchase program. As of December 31, 2006, the company had repurchased approximately 9.5 million shares of common stock for a total cost of $307 million at an average price of $32.26 per share. Of these totals,
7.5 million shares at a total cost of $263 million, or an average cost per share of $35.16, were repurchased in 2006. The company is authorized to repurchase an additional $93 million of its common stock.

Future Cash Requirements.Cash required to meet our
financial needs will be significant. We believe, however, that cash on hand and cash flows from continuing operations will be sufficient to fund planned capital expenditures and interest payments on our indebtedness through the end of 2007. In 2007,
the company has $123 million of scheduled long-term debt principal payment requirements. The company intends to refinance the 2007 principal payments at the time of maturity with the use of a combination of short-term and long-term borrowings,
depending on interest rate and market conditions. Management believes that the companys credit ratings, asset base and historical financial performance will allow these refinancings to be completed at attractive interest rates.

Other Information

SFAS
No. 158.In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 158, Employers Accounting for Defined Benefit
Pension and Other Post Retirement Plansan amendment of FASB Statements No. 87, 88, 106, and 132(R)(SFAS No. 158). SFAS No. 158 requires entities to recognize the funded status of their defined benefit pension
plans in the balance sheet, measured as the difference between the fair value of the plan assets less the projected benefit obligation. Any resulting asset or liability will be fully recognized in the balance sheet. SFAS No. 158 also requires
the actuarial measurement date to be at the end of the entitys fiscal year and expanded disclosure in the footnotes to the financial statements. SFAS No. 158 is effective for fiscal years ending after December 15, 2006 for entities
with publicly traded equity securities, and requires prospective application, with the initial recognition of the funded status being recognized as a component of other comprehensive income. The company adopted SFAS No. 158 on December 31,
2006. As a result of adopting SFAS No. 158, the company recorded a $14 million decrease in accumulated other comprehensive income, net of tax of $5 million. See Note 10 of the Notes to Financial Statements.

SAB 108.In September 2006, the Securities and Exchange
Commission issued Staff Accounting Bulletin No. 108, Considering the effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements(SAB 108), which provides interpretive guidance on
the consideration of the effects of prior year misstatements in quantifying

current year misstatements for the purpose of a materiality assessment. SAB 108 is effective for fiscal years ending after November 15, 2006. The
adoption of this standard at December 31, 2006 did not have an impact on the companys financial condition, results of operations or cash flows.

SFAS No. 157.In September 2006, the FASB issued SFAS No. 157, Fair Value Measurement (SFAS
No. 157). SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements, but does not require any new fair value
measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The company will adopt SFAS No. 157 in the first quarter of 2008. The Company is in the process
of determining the effect, if any, the adoption of SFAS No. 157 will have on the consolidated financial statements.

FIN 48.In July 2006, the Financial Accounting Standards Board issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes(FIN
48). In summary, FIN 48 requires that all tax positions subject to Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes, be analyzed using a two-step approach. The first step requires an entity to
determine if a tax position is more-likely-than-not to be sustained upon examination. In the second step, the tax benefit is measured as the largest amount of benefit, determined on a cumulative probability basis that is more-likely-than-not to be
realized upon ultimate settlement. FIN 48 is effective for fiscal years beginning after December 15, 2006, with any adjustment in a companys tax provision being accounted for as a cumulative effect of accounting change in beginning
equity. The company adopted FIN 48 on January 1, 2007. The adoption of this standard did not have an impact on the companys financial condition, results of operations or cash flows.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Approximately $1.7 billion of the long-term debt of the company bears interest at fixed rates, and therefore the fair value of these instruments is affected by changes in
market interest rates. The following table presents contractual principal cash flows based upon maturity dates of the companys debt obligations and the related weighted-average contractual interest rates by expected maturity dates for the
fixed rate debt (in millions):

|A | The increase in the fair value of fixed rate debt from December 31, 2005 to December 31, 2006
was due primarily to issuance of $225 million in senior notes in May of 2006, partially offset by repayment of $157 million of fixed rate borrowings during 2006 and higher interest rates at December 31, 2006 compared to 2005.

|B | Excludes unamortized discount of $7 million at December 31, 2006 and unamortized premium of
$4 million at December 31, 2005.
|- | ----------------------------------------------------------------------------------------------------------------------------



|C | Represents the average interest rate of total fixed rate debt outstanding at the end of the period.
|- | ---------------------------------------------------------------------------------------------------



|D | As of December 31, 2006, the weighted-average interest rate on the $581 million of borrowings
under our $750 million revolving line of credit was 5.79%. The interest rate on the line of credit is based on LIBOR plus 0.425%. This rate can range from LIBOR plus 0.27% to LIBOR plus 1% depending on our debt ratings.

Consolidated Financial Statements

NOTE 1. ACCOUNTING POLICIES

General.Plum Creek Timber Company, Inc. (Plum Creek, the company, we, us,
or our), a Delaware Corporation, is a real estate investment trust, or REIT, for federal income tax purposes. At December 31, 2006, the company owned and managed approximately 8.2 million acres of timberlands in the
Northwest, Southern and Northeast United States, and owned and operated ten wood product conversion facilities in the Northwest United States. Included in the 8.2 million acres are about 1.7 million acres of higher and better use
timberlands, which are expected to be sold and/or developed over the next 15 years for residential, recreational or conservation purposes. In addition, the company has approximately 400,000 acres of non-strategic timberlands, which are expected to
be sold over the next five years. In the meantime, these timberlands continue to be used productively in our business of growing and selling timber.

Basis of Presentation.The consolidated financial statements of the company include the accounts of Plum Creek Timber
Company, Inc. and its subsidiaries. Intercompany transactions and accounts have been eliminated in consolidation. All transactions are denominated in United States dollars.

Use of Estimates.The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Business Concentrations.Sales of the companys products are dependent upon the economic conditions of the housing, repair and remodeling,
industrial, and pulp and paper industries. Changes in these industries may significantly affect managements estimates and the companys performance.

Revenue Recognition.Timber sales revenues are recognized when legal ownership and the risk of loss transfers to the
purchaser and the quantity sold is determinable. The company sells timber under delivered log agreements as well as through sales of standing timber (or stumpage). For delivered sales, revenue which includes amounts billed for shipping
and handling (logging and hauling of timber), is recognized when the log is delivered to the customer. Stumpage is sold using primarily pay-as-cut or lump-sum sale agreements. Under a pay-as-cut contract, the purchaser acquires the right to harvest
specified timber on a tract, at an agreed upon price per unit. The sale and any related advances are recognized as revenue as the purchaser harvests the timber on the tract. Under a lump-sum sale, the parties agree to a purchase price for all the
timber available for harvest on a tract of land. Generally, the purchase 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. Therefore, revenue under a lump-sum sale is
recognized each month based on the timber harvested compared to the total estimated timber available to be harvested based on the timber cruise over the term of the contract (usually 12 to 18 months). An adjustment may be required to the extent the
actual timber harvested is different than the estimate of timber available.

Revenues generated from the sale of lumber, plywood, medium density fiberboard
(MDF) and related by-products, primarily wood chips, and amounts billed for shipping and handling, are recognized at the time of delivery. Revenues generated from real estate sales include the sale of higher and better use timberlands
and non-strategic timberlands. In some of these transactions, the company sold timberlands that qualified for like-kind (tax-deferred) exchange treatment under the Internal Revenue Code. Substantially all of these sales involved a third party
intermediary, whereby the third party intermediary received proceeds related to the property sold and then reinvested the proceeds in like-kind property. The proceeds are recorded as revenue when the third party intermediary receives them.

Revenue from real estate sales is recognized in accordance with Statement of Financial Accounting Standards (SFAS) No. 66, Accounting
for Sales of Real Estate. For substantially all of our real estate sales, we receive the entire consideration in cash at closing (Cash Sales). Also at closing, the risks and rewards of ownership transfer to the buyer and we do not
have a

continuing involvement in our properties after they are sold. We recognize revenue under the full accrual method for Cash Sales of real estate when the sale
is consummated (i.e., at closing). On occasion we receive a portion of the real estate sale consideration in the form of a note receivable. Such sales represented less than 2% of our revenue from real estate sales for each of the years in the
three-year period ended December 31, 2006. Under these circumstances, we use the full accrual method of recognizing revenue if the buyers initial and continuing investment is adequate; otherwise, revenue is generally recognized under the
cost recovery method or deposit method, depending on the circumstances. Furthermore, Plum Creek may occasionally sell timberlands to a single buyer under a multi-period contract covering a series of prescheduled closings and/or options. Under these
multi-period contracts, once title and risk of loss have transferred to the buyer for individual properties, the properties sold cannot be returned for a refund. However, deposits for future closings under multi-period contracts may be refunded
under certain circumstances. The company treats each closing under a multi-period arrangement as a separate sale and recognizes revenue in accordance with Emerging Issues Task Force (EITF) No. 00-21, Revenue Arrangements with Multiple
Deliverables. Broker commissions and closing costs of our Real Estate Segment are included in Cost of Goods Sold.

Revenue from development projects is
generally recognized under the full accrual method of accounting because sales generally do not commence until the project is completed. On occasion, revenue from development projects will be recognized under the percentage of completion method when
properties are sold prior to their completion. Less than 5% of our development projects sales during 2006 were sold prior to completion of the project.

Cash and Cash Equivalents.All highly liquid investments purchased with an original maturity of three months or less are
considered to be cash equivalents. Substantially all of the cash and cash equivalents are invested in money market funds. The company periodically reviews the credit rating of the financial institution where the money market funds are maintained.
Additionally, the company considers certain proceeds held in escrow associated with like-kind exchanges as cash equivalents. See Like-Kind Exchanges.

Restricted Cash.The company has restricted cash related to certain advances from a customer associated with lump-sum timber
sales. The company reports this cash as Restricted Advance from Customer until the timber associated with the lump-sum contract is harvested.

Accounts Receivable.Accounts receivable at December 31, 2006 and 2005, is presented net of an allowance for doubtful
accounts of $0.6 million and $0.5 million, respectively. Accounts are deemed past due based on payment terms. The allowance for doubtful accounts represents managements estimate and is based on historical losses, recent collection
history, credit ratings of individual customers and existing economic conditions. Delinquent accounts are charged against the allowance for doubtful accounts to the extent and at the time they are deemed uncollectible.

Like-Kind Exchanges.Plum Creek enters into like-kind
(tax-deferred) exchange transactions to acquire and sell assets, principally timberlands. These transactions include both forward (timberlands sold, followed by reinvestment of proceeds to acquire timberlands) and reverse (timberlands purchased,
followed by receipt of proceeds from timberland sales) like-kind exchanges. The company uses a qualified escrow account to facilitate like-kind exchange transactions. Funds from forward like-kind exchange transactions are included as a current asset
under the description Like-Kind Exchange Funds Held in Escrow because the funds are restricted from being used until the funds are either successfully reinvested in timber and timberlands or the exchange fails and the proceeds are distributed to the
company. Escrow funds held in connection with reverse like-kind exchange transactions are included in Cash and Cash Equivalents because these funds are available upon demand and are not subject to risk of loss. At December 31, 2006 and 2005,
there was $29 million and $7 million of cash from reverse like-kind exchange transactions included in Cash and Cash Equivalents, respectively.

Inventories.Logs, work-in-process and finished goods are stated at the lower of cost or market using the average cost method. Supplies
inventories are stated at cost. Costs for manufactured inventories included raw materials, labor, supplies, energy, depreciation and production overhead. Cost of log inventories included timber depletion, stumpage, associated logging and harvesting
costs, road costs and production overhead.

Timber and Timberlands.Timber and timberlands, including logging roads, are stated at cost less accumulated depletion for timber previously harvested and accumulated road amortization. The company capitalizes timber and timberland purchases
and reforestation costs and other costs associated with the planting and growing of timber, such as site preparation, growing or purchases of seedlings, planting, fertilization, herbicide application and the thinning of tree stands to improve
growth. Timber carrying costs, such as real estate taxes, insect control, wildlife control, leases of timberlands (other than lease payments for the purchase of standing timber, in which case the payments are capitalized) and forest management
personnel salaries and fringe benefits, are expensed as incurred. Costs of major roads are capitalized and amortized over 30 years. Costs for roads that are built to access multiple logging sites over numerous years are capitalized and amortized
over six years. Costs for roads built to access a single logging site are expensed as incurred.

Costs attributable to timber harvested, or depletion, are
charged against income as trees are harvested. Depletion rates are determined annually based on the relationship between net carrying value of the timber plus certain capitalizable silviculture costs expected to be incurred over the harvest cycle
and total timber volume estimated to be available over the harvest cycle. The depletion rate does not include an estimate for either future reforestation costs associated with a stands final harvest or future volume in connection with the
replanting of a stand subsequent to its final harvest. Net carrying value of the timber and timberlands is used to compute the gain or loss in connection with timberland sales. No book basis is allocated to the sale of conservation easements.

Higher and Better Use Timberlands / Real Estate Development.At December 31, 2006, the company owned 8.2 million acres of timberlands, of which approximately 1.7 million acres are higher and better use timberlands, which are expected to be sold and/or developed over
approximately the next 15 years. Prior to the sale and/or development of these acres, these timberlands will be used productively in our business of growing and selling timber.

Properties developed internally (Internal Development) will generally be low-intensity development limited to activities associated with obtaining entitlements and investing in infrastructure, such as
roads and utilities. Larger and more complicated projects, such as destination resorts and master planned communities, will be developed through joint venture arrangements in which we are the minority partner and our involvement is limited to
selling and/or contributing land and exercising certain protective rights (External Development).

Costs associated with a specific real estate
project are capitalized once we determine that the project is viable. Both external and internal costs directly associated with the specific real estate project are capitalized. We capitalize improvements and other development costs, including
interest costs and property taxes, during the development period (capitalized interest and property taxes were less than $1 million in 2006 and 2005). General real estate development costs not related to a specific project and costs incurred before
management has concluded that a project will be successful (e.g. investigatory costs) are expensed as incurred. For real estate projects with multiple parcels, we determine the cost of the individual lots sold by allocating the historical cost of
the land, timber, development and common construction costs on a relative sales value.

CONSOLIDATED FINANCIAL STATEMENTS (continued)



Capitalized costs (including our
book basis in the related timber and timberlands) associated with Internal Developments were $14 million at December 31, 2006. The portion of the capitalized costs related to Internal Development properties that are expected to be sold within
the next year ($3 million) is presented in the Consolidated Balance Sheet at December 31, 2006, as Real Estate Development Properties. The portion that is expected to be sold beyond one year ($11 million) is included in Other Assets. Total
capitalized real estate development costs (including our book basis in the related timber and timberlands) at December 31, 2005 were $31 million, including $5 million included within Other Assets.

The book basis of higher and better use timberlands that are considered held for sale in accordance with Statement of Financial Accounting Standard No. 144,
Accounting for the Impairment or Disposal of Long-Lived Assets (SFAS No. 144), are presented in the Consolidated Balance Sheet as Assets Held for Sale. Total assets held for sale were $82 million at December 31, 2006 and
$43 million at December 31, 2005. Generally, timberlands that are under contract to sell or are listed for sale through an independent broker or through a taxable REIT subsidiary and are expected to be sold within the next year are considered
assets held for sale. The book basis of higher and better use timberlands that do not meet the criteria of SFAS No. 144 are included in Timber and Timberlands. Capitalized costs (including our book basis in the related timber and timberlands)
associated with External Development properties are presented in the Consolidated Balance Sheet as Assets Held for Sale if they are expected to be sold to a joint venture within the next year. External Development properties that are not expected to
be sold to a joint venture within the next year are included in Timber and Timberlands.

Property, Plant
and Equipment.Property, plant and equipment are recorded at cost. Replacements of major units of property are capitalized, and the replaced units are retired. Replacement of minor
components of property and repair and maintenance costs are charged to expense as incurred.

All property, plant and equipment other than manufacturing
machinery (lumber, plywood and MDF) are depreciated using the straight-line method over the estimated useful lives of the related assets. Manufacturing machinery and equipment are depreciated on a units-of-production basis, which approximates a
straight-line basis. Useful lives are 25 years for land improvements, 20 to 45 years for buildings, and 3 to 20 years for machinery and equipment. Leasehold improvements are depreciated over the lease term or estimated useful life, whichever is
shorter. The cost and related accumulated depreciation of property sold or retired are removed from the accounts and any gain or loss is recorded.

Grantor Trusts.The company has a grantor trust that was established for deferred compensation and deferred Plum
Creek shares. See Note 8 of the Notes to Financial Statements. Deferred compensation assets, which include money market and mutual fund investments, are classified as trading securities and are carried at market value. Realized
gains and losses and changes in unrealized gains and losses and a corresponding amount of compensation expense are recorded in the Consolidated Statements of Income.

Plum Creek maintains another grantor trust, which the company uses to fund its non-qualified pension plan obligation. See Note 10 of the Notes to Financial Statements. Money market and mutual fund investments
held by this trust are classified as available for sale securities. The investments are carried at market values on the companys Consolidated Balance Sheet; realized gains and losses are recognized in the Consolidated Statements of
Income; changes in unrealized gains and losses are recorded as other comprehensive income or loss.

Shipping and Handling Costs.Costs incurred for shipping timber and manufactured products are included in cost of goods sold.

Accounting for Share-Based Compensation.In December
of 2004, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS No. 123(R)), which is a revision of SFAS No. 123,
Accounting for Stock-Based Compensation. SFAS No. 123(R) supersedes Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and amends SFAS No. 95, Statement of Cash
Flows. Generally, the approach in SFAS No. 123(R) is similar to the approach described in SFAS No. 123. However, SFAS No. 123(R) requires all share-based payments to employees, including grants of employee stock options, to be
recognized in the income statement based on their fair values. We adopted SFAS No. 123(R) on January 1, 2006, using the modified-

CONSOLIDATED FINANCIAL STATEMENTS (continued)



prospective transition method. Results for prior periods have not been restated, as provided for under the modified-prospective method.

Previously, the company adopted the fair-value-based method of accounting for share-based payments effective January 1, 2002, using the prospective method described
in SFAS No. 148, Accounting for Stock-Based CompensationTransition and Disclosure. Beginning January 1, 2002, the company used the Black-Scholes-Merton formula to estimate the value of stock options granted to employees and
will continue to use this option valuation model under SFAS No. 123(R). The company does not expect the expense for stock options computed in accordance with SFAS No. 123(R) to be materially different than the expense previously computed
under SFAS No. 123.

In addition to stock options, the company also grants restricted stock and restricted stock units, value management awards and
dividend equivalents, a portion of which may be payable in the companys stock. Grants of both value management awards and dividend equivalents represent awards that are classified and accounted for as liabilities under SFAS No. 123(R). As
a result, the expense recognized over the performance period for both value management awards and dividend equivalents will equal the fair value of an award as of the last day of the performance period multiplied by the number of awards that are
earned. Furthermore, SFAS No. 123(R) requires the quarterly expense recognized during the performance period to be based on the fair value of value management awards and dividend equivalents as of the end of the most recent quarter. The company
does not expect the total expense recognized over the performance period for value management awards and dividend equivalents computed in accordance with SFAS No. 123(R) to be materially different than the total expense computed under SFAS
No. 123. However, as a result of the requirement under SFAS No. 123(R) to base the quarterly expense on the current fair value of value management awards and dividend equivalents, the quarterly and annual expense recognized under SFAS
No. 123(R) could be materially different than the quarterly and annual expense we previously recognized under SFAS No. 123.

The adoption of SFAS
No. 123(R) resulted in a cumulative benefit from an accounting change in the Consolidated Statements of Income of $2 million, net of tax, for the year ended December 31, 2006. The cumulative effect adjustment is primarily a result of
changes in expense related to the fair value of the value management awards and dividend equivalents.

SFAS No. 123(R) also requires the benefits of
tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as required under previous literature. This requirement will reduce net operating cash flows and increase net
financing cash flows in periods after adoption. The impact of this change on net operating cash flows and net financing cash flows for the year ended December 31, 2006, was less than $1 million.

Excluding the cumulative effect of the accounting change of $2 million, net of tax, the impact of adopting SFAS No. 123(R) on January 1, 2006 was an increase of
less than $1 million to our income before income taxes, income from continuing operations, and net income for the year ended December 31, 2006 than if we had continued to account for share-based compensation in accordance with SFAS
No. 123. Basic and diluted earnings per share amounts for net income did not change as a result of adopting SFAS No. 123(R).

Other Operating Income.Since 2000, the company has been a member of an industry coalition alleging that lumber exports to the U.S. were unfairly
subsidized. This dispute was resolved during 2006, and Plum Creek received a settlement of $14 million ($13 million net of tax). The settlement is presented in our Consolidated Statements of Income as Gain from Canadian Lumber Settlement.

Periodically the company will recognize gains and losses from miscellaneous asset sales and litigation settlements. Gains recognized for 2006, 2005 and
2004 were $4 million, $5 million and $5 million, respectively, and were reported in our Consolidated Statements of Income as Other Operating Income (Expense), net.

Reclassifications.Certain prior year amounts have been reclassified to conform to the 2006 presentation. The
reclassifications had no impact on operating income or net income.

For segment information, certain
direct segment costs, previously included in corporate and other unallocated expense were reclassified in 2005 and 2004 to conform to the 2006 presentation (see Note 14 of the Notes to Financial Statements).

Capitalized costs associated with Internal Developments are separately stated at December 31, 2006. Previously, these costs were included in Timber and Timberlands.
Accordingly, $31 million was reclassified at December 31, 2005 from Timber and Timberlands.

The book basis of higher and better use timberlands that
are held for sale are separately stated at December 31, 2006. Previously, the book basis of assets held for sale were included in Timber and Timberlands. Accordingly, $43 million was reclassified at December 31, 2005 from Timber and
Timberlands.

New Accounting Pronouncements

SFAS No. 158.In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 158, Employers
Accounting for Defined Benefit Pension and Other Post Retirement Plansan amendment of FASB Statements No. 87, 88, 106, and 132(R)(SFAS No. 158). SFAS No. 158 requires entities to recognize the funded status of
their defined benefit pension plans in the balance sheet, measured as the difference between the fair value of the plan assets less the projected benefit obligation. Any resulting asset or liability will be fully recognized in the balance sheet.
SFAS No. 158 also requires the actuarial measurement date to be at the end of the entitys fiscal year and expanded disclosure in the footnotes to the financial statements. SFAS No. 158 is effective for fiscal years ending after
December 15, 2006 for entities with publicly traded equity securities, and requires prospective application, with the initial recognition of the funded status being recognized as a component of accumulated other comprehensive income (loss). The
company adopted SFAS No. 158 on December 31, 2006. As a result of adopting SFAS No. 158, the company recorded a $14 million decrease in accumulated other comprehensive income (loss), net of tax of $5 million. See Note 10 of the Notes
to Financial Statements.

SAB 108.In
September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 108, Considering the effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements(SAB
108), which provides interpretive guidance on the consideration of the effects of prior year misstatements in quantifying current year misstatements for the purpose of a materiality assessment. SAB 108 is effective for fiscal years ending
after November 15, 2006. The adoption of this standard at December 31, 2006 did not have an impact on the companys financial condition, results of operations or cash flows.

SFAS No. 157.In September 2006, the FASB issued SFAS
No. 157, Fair Value Measurement (SFAS No. 157). SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value
measurements, but does not require any new fair value measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The company will adopt SFAS No. 157 in the
first quarter of 2008. The Company is in the process of determining the effect, if any, the adoption of SFAS No. 157 will have on the consolidated financial statements.

FIN 48.In July 2006, the Financial Accounting Standards Board issued FASB Interpretation
No. 48, Accounting for Uncertainty in Income Taxes(FIN 48). In summary, FIN 48 requires that all tax positions subject to Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes, be
analyzed using a two-step approach. The first step requires an entity to determine if a tax position is more-likely-than-not to be sustained upon examination. In the second step, the tax benefit is measured as the largest amount of benefit,
determined on a cumulative probability basis that is more-likely-than-not to be realized upon ultimate settlement. FIN 48 is effective for fiscal years beginning after December 15, 2006, with any adjustment in a companys tax provision
being accounted for as a cumulative effect of accounting change in beginning equity. The company adopted FIN 48 on January 1, 2007. The adoption of this standard did not have an impact on the companys financial condition, results of
operations or cash flows.

During 2006, Plum Creek acquired approximately 98,000 acres of timberlands primarily located in Oregon for $111
million. These purchases were financed primarily by using the funds from tax-deferred exchanges and our line of credit, and have been accounted for as asset acquisitions. Timberland dispositions during 2006 were approximately 112,000 acres, of which
57,000 acres were located in the Northern Resources Segment and 55,000 acres were located in the Southern Resources Segment.

During 2005, Plum Creek
acquired approximately 754,000 acres of timberlands located in Northern Michigan, Arkansas and Florida for $501 million. These purchases were financed primarily by using proceeds from the issuance of debt and funds from tax-deferred exchanges and
have been accounted for as asset acquisitions. Timberland dispositions during 2005 were approximately 232,000 acres, of which 63,000 acres were located in the Northern Resources Segment and 169,000 acres were located in the Southern Resources
Segment.

During 2005, the company sold certain subsurface property rights (its remaining coal reserves, excluding coalbed methane, oil and gas reserves) in
Buchanan County, Virginia. The sale of these properties is reflected in our Consolidated Statements of Income as Gain on Sale of Properties, net of tax. For the year ended December 31, 2005, we received sales proceeds of $21 million and, after
deducting our book basis of $1 million, recorded a gain of $20 million. See Note 14 of the Notes to Financial Statements.

The companys Real Estate
Segment consists of sales of higher and better use timberlands and sales of non-strategic timberland. Occasionally, non-strategic timberlands are sold at a loss. Each real estate sale is evaluated for a potential impairment in accordance with SFAS
No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. During 2006, the company recorded impairment losses of $2 million in connection with the potential sale of non-strategic timberlands, which had a book basis of $5
million. During 2005, the company recorded impairment losses of $1 million in connection with the potential sale of non-strategic timberlands, which had a book basis of $4 million. During 2004, the company recorded impairment losses of $21 million
in connection with the potential sale of non-strategic timberlands, which had a book basis of $45 million; substantially all of these properties were sold during 2004. The impairment losses are included in Cost of Goods Sold for Real Estate in our
Consolidated Statements of Income.

During 2005, the companys Southern Resources Segment recognized a $2 million loss, representing the book basis of
the timber volume destroyed as a result of severe winds from Hurricane Katrina on approximately 350,000 acres in Mississippi.

During the fourth quarter of 2004, the company concluded it had excess production capacity at one of its mills; and
therefore, concluded that the mills long-lived assets were impaired. The company recorded an impairment loss of $9 million during the

fourth quarter of 2004 by writing the carrying value of the mills long-lived assets of $14 million down to their estimated fair value of $5 million.
The impairment loss of $9 million is reflected in the operating income of our Manufactured Products Segment and included in Cost of Goods Sold for Manufacturing in our Consolidated Statements of Income. The estimated fair value was computed
based on expected future cash flows discounted at the risk-free rate of interest.

Plum Creek had been a party to a joint operating agreement with Geomet,
Inc., a coalbed methane developer, with whom the company jointly explored for and developed coalbed methane gas found on certain of Plum Creeks timberlands in West Virginia and Virginia. During 2004, the company sold its working interest in
the joint operating agreement to Geomet, Inc. See Note 14 of the Notes to Financial Statements.

NOTE 4. INCOME TAXES

Plum Creek has elected to be taxed as a REIT under sections 856-860 of the United States Internal Revenue Code. A REIT is generally not subject to corporate-level income
tax if it distributes 100% of its taxable income to shareholders and satisfies other organizational and operational requirements as set forth in the Internal Revenue Code. If a company fails to qualify as a REIT in any taxable year, it will be
subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years.

Plum Creek conducts its activities through various wholly-owned operating partnerships. The activities of the operating partnerships consist primarily of sales of timber under pay-as-cut contracts, and the income from
such sales is not subject to corporate income tax. The book basis of the REITs assets and liabilities exceeds its tax basis by approximately $2.3 billion at December 31, 2006. Plum Creeks wholly-owned taxable REIT subsidiaries file
a consolidated federal income tax return.

As a consequence of the October 6, 2001 merger with The Timber Company, which involved merging a taxable
entity into a nontaxable entity, Plum Creek will generally be subject to corporate-level tax (built-in gains tax) if the company makes a taxable disposition of certain property acquired in the merger with The Timber Company within the ten-year
period following the merger date. The built-in gains tax applies to gains from such asset sales to the extent that the fair value of the property exceeds its tax basis at the merger date. Built-in gains tax is generally not payable on dispositions
of property to the extent the proceeds from such dispositions are reinvested in qualifying like-kind replacement property. The built-in gains tax does not apply to income generated from the harvesting and sale of timber.

In connection with our merger with The Timber Company, we wrote-off all of The Timber Companys deferred income tax liability related to timber and timberlands
except for $11 million. The $11 million deferred income tax liability related to the book-tax basis difference of timber and timberlands that were expected to be sold, and subject to, the built-in gains tax during the ten-year period ending
October 6, 2011. During the period October 6, 2001 to December 31, 2006, the $11 million deferred income tax liability was reduced by $1 million due to the payment of tax in connection with sales of timberlands subject to the built-in
gains tax.

In accordance with Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes,we remeasure the amount of
deferred income taxes needed in connection with expected sales of timberlands subject to the built-in gains tax each quarterly reporting period. In 2005, we reduced our deferred tax liability associated with timber and timberlands by $5 million and
correspondingly recorded a deferred tax benefit of $5 million. Based on projected timberland sales subject to the built-in gains tax for the period December 31, 2006 to October 6, 2011, and our ability to successfully reinvest proceeds in
like-kind properties, we estimate we need a deferred tax liability of approximately $5 million. As a result, no adjustment to the deferred tax liability associated with built-in gains tax was made in 2006.

Plum Creek conducts certain non-REIT activities through various wholly-owned taxable REIT subsidiaries, which are subject to corporate-level income tax. These activities
include the companys manufacturing operations, the harvesting and sale of logs, and the development and/or sale of some of the companys higher and better use timberlands.

NOTES TO
CONSOLIDATED FINANCIAL STATEMENTS (continued)



Deferred income tax liabilities
at December 31, 2006 and 2005, are net of deferred tax assets included in current assets of $7 million and $17 million, respectively. In connection with the adoption of SFAS No. 158, Employers Accounting for Defined Benefit
Pension and Other Post Retirement Plans on December 31, 2006, we recorded a deferred tax asset of $5 million (see Note 10 of the Notes to Financial Statements).

The company filed its federal income tax return as part of Georgia-Pacifics consolidated income tax return for all tax years through the date of the merger with The Timber Company on October 6, 2001. Under
the agreement governing the terms of the merger with The Timber Company, the company remains liable to Georgia-Pacific for any additional tax that would result from audit adjustments by the Internal Revenue Service (the Service) and by
state and local taxing authorities. The Service has completed all examinations of Georgia-Pacifics consolidated income tax returns through 2000. Georgia-Pacifics consolidated income tax return for 2001 is currently under examination.
Additionally, the Service has completed examinations of the federal income tax return of Plum Creek Timber Company, Inc. and the consolidated federal income tax return of the wholly-owned taxable REIT subsidiaries for the year 2003. Plum Creek has
no open tax years prior to 2003.

January 2009 and entered into a new $750 million revolving line of credit agreement that matures in June 2011. The revolving line of credit may be increased to $1 billion subject to certain terms and conditions. As of December 31, 2006, the
weighted-average interest rate for the borrowings on the line of credit was 5.79%. The interest rate on the line of credit is based on LIBOR plus 0.425%. This rate can range from LIBOR plus 0.27% to LIBOR plus 1% depending on our debt ratings.
Subject to customary covenants, the line of credit allows for borrowings from time to time up to $750 million, including up to $100 million of standby letters of credit. Borrowings on the line of credit fluctuate daily based on cash needs. As of
December 31, 2006, we had $581 million of borrowings and $5 million of standby letters of credit outstanding; $164 million remained available for borrowing under our line of credit. As of January 5, 2007, $243 million of the
borrowings under our line of credit was repaid.

In April 2006, the company filed with the Securities and Exchange Commission a shelf registration statement
under which Plum Creek Timber Company, Inc., from time to time, may offer and sell any combination of preferred stock, common stock, depositary shares, warrants and guarantees, and under which Plum Creek Timberlands, L.P. the companys
wholly-owned operating partnership, may from time to time, offer and sell debt securities. The shelf registration statement expires on April 25, 2009.

On May 2, 2006, Plum Creek Timberlands, L.P. (the Partnership), issued off the shelf registration statement $225 million aggregate principal amount of its senior notes with a coupon rate of 5.875%, at a market price of
96.686% of the principal amount. The net proceeds of $216 million were used primarily to repay outstanding debt maturing during 2006. The notes mature in 2015 and are fully and unconditionally guaranteed by Plum Creek Timber Company, Inc.

In May of 2005, the company entered into a $50 million one-year term loan agreement to finance the acquisition of approximately 35,000 acres of Florida
timberlands. This loan was repaid in May of 2006.

CONSOLIDATED FINANCIAL STATEMENTS (continued)



In November of 2005, the
Partnership issued $300 million aggregate principal amount of its senior notes with a coupon rate of 5.875% at a market price of 99.731% of the principal amount, maturing in 2015. The net proceeds of $297 million were used primarily to purchase
timberlands. The Senior Notes due 2015 are fully and unconditionally guaranteed by Plum Creek Timber Company, Inc.

During 2006, the company made debt
principal payments totaling $207 million. During 2005, the company made debt principal payments totaling $47 million.

The senior notes are structurally
subordinated to all unsecured debt and liabilities of the Partnerships subsidiaries, and junior in right of payment to secured debt of the Partnerships subsidiaries to the extent of the value of the assets secured by such debt. At
December 31, 2006, the total amount of unsecured debt and liabilities of the Partnerships subsidiaries was approximately $859 million, and the total amount of secured debt of the Partnerships subsidiaries was approximately $13
million, representing mortgage notes secured by certain manufacturing assets. In the event of insolvency, bankruptcy, liquidation, reorganization, dissolution, winding up of the Partnerships business or other similar process, the assets of the
Partnerships subsidiaries will be available to pay the amounts due on the senior notes only after the secured and unsecured indebtedness of the Partnerships subsidiaries has been repaid in full.

The Senior Notes (excluding the Senior Notes due 2011) and the First Mortgage Notes are redeemable prior to maturity subject to a premium on redemption, which is based
upon interest rates of United States Treasury securities having similar average maturities as these notes. The premium that would have been due upon early retirement approximated $114 million at December 31, 2006, and $148 million at
December 31, 2005. The Senior Notes are unsecured. The First Mortgage Notes are collateralized by substantially all of the property, plant and equipment of the lumber, plywood and MDF manufacturing facilities. The Senior Notes due 2011 are not
redeemable prior to maturity.

The aggregate maturities on all debt agreements and the line of credit are as follows as of December 31, 2006 (in
millions):

The companys borrowing agreements contain various restrictive covenants, including limitations on harvest
levels, sales of assets, the incurrence of indebtedness and making restricted payments (such as payments of cash dividends or stock repurchases). The borrowing agreements limit our ability to make restricted payments (see Note 7 of the Notes to
Financial Statements) based on available cash, which is generally our net income (excluding gains on the sale of capital assets) after adjusting for non-cash charges (such as depreciation and depletion), changes in various reserves, less capital
expenditures and principal payments on indebtedness that are not financed. Additionally, the amount of available cash may be increased by the amount of proceeds from the sale of higher and better use properties and, under certain circumstances, by
50% of the amount of net proceeds from the sale of other assets. Furthermore, our line of credit requires that we maintain certain interest coverage and maximum leverage ratios. The company was in compliance with all of our borrowing agreement
covenants as of December 31, 2006.

NOTE 8. FINANCIAL INSTRUMENTS

The carrying amounts of cash and cash equivalents and notes receivable approximate fair value due to the short-term maturities of these instruments. The estimated fair value of the companys debt was
approximately $2.38 billion and $2.32 billion at December 31, 2006 and 2005, respectively, and the carrying amount was $2.32 billion and $2.23 billion at December 31, 2006 and 2005, respectively. The fair value of the
companys publicly-traded debt (i.e. Senior Notes due 2015) is estimated using market quotes; the fair value of the remainder of the companys debt is estimated using current interest rates for similar obligations with like maturities.

Certain investments in the grantor trusts relate to the companys non-qualified pension plans and are classified as available-for-sale securities.
The company has invested in various money market, debt and equity mutual funds and plans to use these investments to fund its non-qualified pension obligations. The fair value of these investments was $19 million and $18 million at December 31,
2006 and 2005, respectively. Unrealized holding gains and losses are included as a component of accumulated other comprehensive income, unless a permanent impairment has occurred, which is then charged to expense. Unrealized holding gains relating
to mutual fund investments were approximately $4 million and $2 million at December 31, 2006 and 2005, respectively. The company records changes in unrealized holding gains in Other Comprehensive Income. Realized gains and losses were less than
$1 million in 2006, 2005, and 2004. See Note 10 of the Notes to Financial Statements for discussion of the companys Pension Plans.

Certain investments in the
grantor trusts relate to the companys deferred compensation plans and are classified as trading securities. Deferred compensation amounts are invested in various money market, debt and equity mutual funds. The company plans to use these
investments to fund deferred compensation obligations. The fair value of these investments was $8 million at both December 31, 2006 and 2005. Unrealized holding gains related to mutual fund investments were $1 million at both
December 31, 2006 and 2005. The change in unrealized holding gains has been recognized in the companys Consolidated Statements of Income resulting in a gain of less than $1 million in 2006, a loss of less than $1 million in 2005, and a
gain of $1 million in 2004. Realized gains and losses were less than $1 million in 2006, 2005, and 2004. Deferred compensation obligations are included in Other Liabilities and were $8 million at both December 31, 2006 and 2005.

NOTES TO
CONSOLIDATED FINANCIAL STATEMENTS (continued)



The underfunded status of our
plans of $34 million at December 31, 2006, is recognized in our Consolidated Balance Sheet as a current pension liability of $3 million and long-term pension liability of $31 million. The accumulated benefit obligation was $100 million and $96
million at December 31, 2006 and December 31, 2005, respectively.

We adopted the recognition and disclosure provisions of SFAS No. 158,
Employers Accounting for Defined Benefit Pension and Other Postretirement Plans (SFAS No. 158) on December 31, 2006. Under SFAS No. 158, we are required to recognize the funded status for our defined benefit
plans in our December 31, 2006, Consolidated Balance Sheet. The funded status is the difference between the fair value of plan assets and the projected benefit obligation. Recognizing the funded status resulted in a corresponding adjustment to
accumulated other comprehensive income, net of tax. The adjustment to accumulated other comprehensive income represents the net unrecognized actuarial losses and unrecognized prior service costs. Previously under the provisions of SFAS No. 87,
Employers Accounting for Pensions(SFAS No. 87), these amounts were netted against the plans funded status in our Consolidated Balance Sheets. These amounts will be subsequently recognized as pension cost pursuant
to our historical accounting policy for amortizing such amounts. The actuarial gains and losses that arise in subsequent periods and that are not recognized as pension cost in the same periods will be recognized as a component of other comprehensive
income, and will be subsequently recognized as a component of pension cost consistent with our historical policy for amortizing such amounts.

The adoption
of SFAS No. 158 had no effect on our Consolidated Statements of Income for the year ended December 31, 2006, or for any prior period presented, and it will not affect our operating results in future periods. The incremental effect of
applying SFAS No. 158 on individual line items on our December 31, 2006 Consolidated Balance Sheet is as follows:

As of December 31, 2006, amounts that have not yet been recognized in pension cost and are included in
accumulated other comprehensive income (loss) are as follows:

|                    
|                    

During 2007, we expect $1 million of net actuarial loss and prior service cost to be recognized as a component of
pension cost.

Under SFAS No. 158, we recognized a liability in our Consolidated Balance Sheet at December 31, 2006, for our defined benefit
pension plans that are underfunded. Under the provisions of SFAS No. 87, the unfunded accrued pension cost at December 31, 2005 is set forth in the following table (in millions):

To develop the expected long-term rate of return on plan assets assumption, the company considered the current
level of expected returns on risk free investments (primarily government bonds), the historical level of the risk premium associated with the other asset classes in which the portfolio is invested and the expectations for future returns on each
asset class. The expected return for each asset class was then weighted based on the target asset allocation to develop the expected long-term rate of return on plan assets assumption for the portfolio. This resulted in the selection of the 7.75%
assumption as of January 1, 2006 and 2005.

Most of the companys salaried and all hourly employees who complete one year of service in which they
work at least 1,000 hours are eligible to participate in the plan. Participants vest after five years of service. The cash balance benefits for salaried employees is determined based primarily on certain percentages of compensation, age, years of
service and interest accrued based on the 30-year Treasury bond rate. Participants who were employees of the company on September 1, 2000, earn benefits based on the greater of the cash balance formula or a monthly pension benefit that is
principally based on the highest monthly average earnings during any consecutive sixty-month out of 120-month period and the number of years of service credit. The benefits to hourly employees are generally based on a fixed amount per year of
service.

The company maintains a qualified defined benefit pension plan and two supplemental (non-qualified) defined benefit pension plans. The
companys contributions to these plans vary from year to year. It is the companys policy to fund the qualified plan annually by either the value of the benefits earned during the year or, if more, the amount such that the fair value of
plan assets equals or exceeds the actuarially computed accumulated benefit obligation (the approximate actuarially computed current pension obligation if the plan was discontinued).

The company has the same funding policy for the non-qualified plans. However, assets related to the non-qualified plans are held in a grantor trust and are subject to the claims of creditors in the event of
bankruptcy. As a result, pension assets for the

non-qualified plans are not considered plan assets, and therefore, have not been netted against our pension liability. Pension assets for the non-qualified
plans are included in Investment in Grantor Trusts and the related pension liability is included in Other Liabilities and Other Current Liabilities in our Consolidated Balance Sheet. At December 31, 2006 and
2005, the accumulated benefit obligation for the non-qualified plans was $19 million and $17 million, respectively. The fair value of assets held in a grantor trust associated with the non-qualified plans was $19 million at
December 31, 2006, and $18 million at December 31, 2005.

As a result of the companys funding policy, annual qualified pension
contributions and grantor trust funding are significantly impacted by investment returns and changes in interest rates. Based on current interest rates and expected investment returns, the company expects 2007 contributions to the qualified pension
plan to range between $2 million and $5 million. Additionally, during 2007 the company expects to contribute between $1 million and $3 million to its grantor trust associated with the non-qualified plans.

The following table presents expected future benefit payments projected based on the same assumptions used by the company to measure the benefit obligation and estimate
future employee service (in millions):

It is the companys investment policy to achieve maximum returns at a reasonable risk for pension assets over
a full market cycle. The company uses eight fund managers to capture favorable returns in various asset classes and to diversify risk. At December 31, 2006, target allocations for the various asset classes are as follows:

Pension assets are analyzed at
least quarterly and rebalanced as needed to maintain the above target allocations. To further reduce risk, fund managers are required to invest in a diversified portfolio. No more than 5% of an equity portfolio can be invested in a single company
and fund managers are expected to be well diversified with respect to industry and economic sectors. No more than 10% of a fixed income portfolio can be invested in a single issuer (other than U.S. treasuries). Equity investments are limited to
common stocks, common stock equivalents and preferred stock. Fixed income investments are limited to U.S. treasuries, agencies of the U.S. Government, domestic corporations, municipalities, domestic banks, and other U.S. financial institutions.
Furthermore, hedge funds are used to reduce market risk and generate absolute returns regardless of market direction by employing limited use of derivative instruments, selling securities short, and buying and selling futures and options contracts.

Over a full market cycle, the investment goal for large capitalization domestic equities and fixed income investments is to exceed the applicable benchmark
(e.g., S&P 500 Index) by one-half of one percent per annum, and the investment goal for small and mid-size capitalization domestic equities and international equities is to exceed the applicable benchmark (e.g., Russell 2000 Value Index) by one
percent. The investment goals are net of related fees.

Thrift and Profit Sharing Plan.The company sponsors an employee thrift and profit sharing plan under Section 401(k) of the Internal Revenue Code. This plan covers substantially all full-time employees. The company matches
employee contributions of up to six percent of compensation at rates ranging from 35 to 100 percent, depending upon financial performance.

Amounts
charged to expense relating to the companys thrift and profit sharing plan were $6 million in 2006 and $5 million each for 2005 and 2004. The employer match for each of the three years was 100%.

Other Benefit Plans.Certain executives and key
employees of the company participate in incentive benefit plans, which provide for the granting of shares and/or cash bonuses upon meeting performance objectives. See Note 11 of the Notes to Financial Statements.

NOTE 11. SHAREBASED COMPENSATION PLANS

Plum Creek has a
stockholder approved Stock Incentive Plan that provides for the award of non-qualified stock options, restricted stock and restricted stock units, value management awards and dividend equivalents.

Under Plum Creeks Stock Incentive Plan (the Plan), as amended in May 2004, there are 12.4 million shares of common stock reserved and eligible for
issuance. At December 31, 2006, 3.3 million shares of the 12.4 million reserved shares have been used and, therefore, 9.1 million shares remain available for grants of non-qualified stock options, grants of restricted stock and
restricted stock units, or payments of vested value management awards and dividend equivalents. The number of shares to be issued in connection with value management awards and dividend equivalents is not determined until the end of their respective
performance periods. New shares are issued for payment under the Plan for awards that pay out in shares or where the participant can elect payment in shares.

Stock Options.Under the Plan, non-qualified stock options may be granted to any officer, director, employee, consultant or
advisor of the company. Each stock option granted allows the recipient the right to purchase the companys common stock at the fair market value of the companys common stock on the date of the grant. Generally, the stock options have a
ten-year term and vest over a four-year period at a rate of 25% per year. Under the Plan, the exercise price of an option may not be reduced.

The expected term of the options represents the estimated period of time until exercise and is based on the
vesting period of the award and the historical exercise experience of similar awards. All participants were assumed to have similar exercise behavior. Expected volatility is based on historical volatility over the approximate expected term of the
option.

Restricted Stock.Under the Plan,
restricted stock of the company may be awarded to certain directors, officers and employees of the company. Restricted stock may not be sold, assigned, transferred, pledged or otherwise disposed of for a period of time from the date on which the
restricted stock was granted. The recipients of restricted stock generally have the rights of stockholders of the company with respect to voting and receipt of dividends during the restricted period. Restricted stock generally vests between six
months and three years from the grant date. Termination of employment prior to the end of the restricted period will generally require the return of the restricted stock to the company. The weighted-average grant date fair values of restricted stock
awards granted for the years ended December 31, 2006, 2005 and 2004 were $35.98, $36.99 and $33.48 respectively. The fair value of restricted stock is based on the closing price of Plum Creeks common stock on the date of grant.

The total fair value of restricted stock awards that vested during the years ended December 31, 2006, 2005 and
2004 was less than $1 million each.

Restricted Stock Units.Under the Plan, restricted stock units may be awarded to certain directors, officers and employees of the company. No restricted stock units were awarded prior to 2006. The recipients of restricted stock units generally have the
right to receive a cash amount equal to any dividends paid on the companys common stock during the restriction period and upon vesting, the right to receive an equal number of shares of the companys common stock. Restricted stock units
generally vest over a four-year period at a rate of 25% per year. If employment is terminated prior to vesting, all unvested restricted stock units are forfeited. The weighted-average grant date fair value of restricted stock units granted for
the year ended December 31, 2006 was $35.63. The fair value of restricted stock units is based on the closing price of the companys common stock on the date of grant.

Restricted stock unit activity was as follows for the year ended December 31, 2006:

Value Management Awards.Value management awards provide incentive compensation to participants that is contingent upon the companys performance over a three-year period measured against the performance of peer groups consisting of forest
products companies, the S&P 500 Index and the Morgan Stanley REIT Index over the same period (Peer Group).

Value management awards are earned in whole or in part based on a sliding scale. No value management award is earned if the companys total shareholder return is below the 50thpercentile of the Peer Group. The full value management award is earned if the companys total shareholder return is above the 75thpercentile. A unit has a face value of $100. The value of an award between the 50thand 75thpercentiles is
based on a sliding scale between 0% and 200% of the face value. Amounts earned, if any, are paid in the quarter immediately following the end of the three-year performance period. Unless otherwise specified by the participant, each payment will be
paid in cash, except that any officer not in compliance with the companys stock ownership guidelines is required to receive up to half of the payment value in the companys common stock. Generally, to be entitled to the payment, a
participant must be employed by the company on the last day of the performance period.

|B | Maximumaward value is based on a unit value of $200.
|- | ----------------------------------------------------

The three-year performance period for the
2004 grants ended on December 31, 2006; amounts earned of $2.5 million, based on a unit value of $74, were paid (primarily in cash) during the first quarter of 2007. There were no value management award payments during the first quarter of 2006
because no awards had a performance period ending December 31, 2005. The three-year performance period for the 2002 grants ended on December 31, 2004; amounts earned of $9 million were paid (primarily in cash) during the first quarter of
2005. The three-year performance period for the 2000 grants ended on December 31, 2002; amounts earned of $8.9 million, based on a unit value of $200, were paid half during the first quarter of 2003 and half during the first quarter 2004.

Dividend Equivalents.Under the Plan,
dividend equivalents may be granted in connection with stock options. Dividend equivalents represent the right to receive a payment equal in value to the per-share dividend paid over a five-year period by the company multiplied by the number of
unexercised stock options. No dividend equivalents were awarded during 2006.

For awards granted in
2005 and 2004, each year during the five-year performance period, a participant may be eligible to earn a percentage of the companys current year dividend plus a percentage of prior year unearned dividends to the extent that the company has
achieved a minimum level of total shareholder return. The total shareholder return computation consists of the companys stock price appreciation plus dividends paid. The specific percentage to be applied to any such earned dividends for a
given year of the performance period is contingent upon the companys performance for that year measured against the performance of the Peer Group. Dividends are earned in whole or in part based on a sliding scale. If the companys total
shareholder return is below the 50thpercentile of the Peer Group, the percentage amount is zero. If the
companys total shareholder return is at or above the 75thpercentile, the full amount of the dividend is
earned. If the companys relative performance is between the 50thand the 75thpercentiles, dividend equivalents are valued based on a sliding scale between 50% and 100% of the dividends paid during the year. The minimum level
of total shareholder return must be at least 5.5% on an annualized basis.

For awards granted prior to 2004, each year during the respective five-year
performance period, a participant may earn an amount equal to the companys current year dividend plus prior year unearned dividends to the extent the companys total shareholder return on an annualized basis equals or exceeds 13% for 15
trading days out of any 30 trading day period in any given year.

Payments related to any earned
dividend equivalents are made at the end of the five-year performance period. Amounts earned, if any, are paid in the quarter immediately following the end of the five-year performance period. Unless otherwise specified by the participant, each
payment is paid in cash, except that any officer not in compliance with the companys stock ownership guidelines is required to receive up to half of the payment value in the companys common stock. If a participant terminates employment
prior to the end of the five-year performance period, a cash payment is made for any performance goals achieved in connection with vested stock options through the last day of employment. Payment related to unvested stock options and performance
goals achieved after termination of employment are forfeited. At December 31, 2006, 1.5 million dividend equivalents, net of forfeitures, granted to employees, officers and directors of the company were outstanding.

|A | The estimated fair value includes unrecognized compensation expense.

|B | Maximum award value is calculated based on earned dividends to date plus potential future unearned dividends assuming a quarterly dividend rate of $0.42 per share.
|- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------

The five-year performance period for the 2002 grants ended on December 31, 2006; amounts earned of $1.7 million were paid (primarily in
cash) during the first quarter of 2007. The five-year performance period for the 2001 grants ended on December 31, 2005; amounts earned of $3 million were paid (primarily in cash) during the first quarter of 2006. The five-year performance
period for the 2000 grants ended on December 31, 2004; amounts earned of $3 million were paid (primarily in cash) during the first quarter of 2005. No dividends equivalents were awarded prior to 2000.

Measurement of Compensation Costs for Value Management Awards and Dividend Equivalents.Grants of both value management awards and dividend equivalents represent awards that are classified and accounted for as liabilities under SFAS No. 123(R). As a result, the expense recognized
over the performance period for both value management awards and dividend equivalents will equal the fair value (i.e., cash value) of an award as of the last day of the performance period multiplied by the number of awards that are earned.
Furthermore, SFAS No. 123(R) requires the quarterly expense recognized during the performance period to be based on the fair value of value management awards and dividend equivalents as of the end of the most recent quarter. Prior to the end of
the performance period, compensation costs for value management awards and dividend equivalents are based on the awards most recent quarterly fair values and the number of months of service rendered during the performance period.

Fair values for value management awards and dividend equivalents are computed based on our historical relative total shareholder return compared to the Peer Group from
the beginning of the performance period to the end of the most recent quarter, and our simulated relative total shareholder return through the end of the performance period. The simulated total shareholder return of the company and the Peer Group is
computed using a Monte Carlo simulation. The key assumptions used in the simulation of the companys and the Peer Groups total shareholder return are volatility, beta (the measure of how Plum Creeks stock moves relative to the
market as a whole), risk-free interest rate, and expected dividend yield. Additionally, the fair value of dividend equivalents assumes that our current quarterly dividend of $0.42 per share will remain constant through the end of the performance
period.

Accounting for Share-Based Compensation.The company expenses share-based employee compensation in accordance with the fair value recognition provisions of SFAS
No. 123(R), Share-Based Payment. Under the modified-prospective method adopted by Plum Creek on January 1, 2006, share-based employee compensation cost is recognized using the fair value method for all employee awards granted,
modified, or settled on or after January 1, 2006 (see Accounting for Share-Based Compensation in Note 1 of the Notes to Financial Statements). Stock options and most restricted stock units vest 25% per year over a four-year
vesting period. Compensation cost related to these graded vesting awards is recognized using the straight-line method over the four-year vesting period. Total compensation expense for the above share-based compensation plans (including both awards
paid in stock and cash) was approximately $9 million, $9 million and $13 million for the years ended December 31, 2006, 2005, and 2004, respectively. For the years ended December 31, 2006, 2005, and 2004, the company recognized $2 million,
$2 million, and $3 million, respectively, in tax benefits associated with share-based compensation plans. At December 31, 2006, there was $12 million of total unrecognized compensation cost related to nonvested share-based compensation
arrangements granted under the Plan. That cost is expected to be recognized over a weighted-average period of approximately 3 years.

PLUM CREEK TIMBER COMPANY, INC.

NOTES TO
CONSOLIDATED FINANCIAL STATEMENTS (continued)



NOTE 13. COMMITMENTS AND
CONTINGENCIES

Contingencies.The
company is subject to regulations regarding forest and harvest practices and is, from time to time, involved in various legal proceedings, including environmental and regulatory matters, incidental to its business. Moreover, the company is currently
in the early stages of several lawsuits related to property damage caused by various sources (Property Damage Litigations). The company believes it is more likely than not that the Property Damage Litigations will be resolved favorably.
However, the final outcome of any legal proceeding is subject to many variables and cannot be predicted with any degree of certainty. The company believes that there are meritorious defenses for these claims and is vigorously defending these
matters.

Environmental Contingencies.In
connection with the October 6, 2001 merger with The Timber Company, Plum Creek agreed to indemnify Georgia-Pacific for substantially all of the liabilities attributed to The Timber Company. During 2003, Georgia-Pacific provided Plum Creek with
information about the existence of mine tailings and approximately 4.5 billion gallons of acidic surface water on approximately 90 acres in Hot Spring County, Arkansas, on former Georgia-Pacific properties (Arkansas Environmental
Issue). Barite mining and related activities were conducted on the site between 1939 and 1981 in part by lessees of an entity that was acquired by Georgia-Pacific. The site is currently being investigated and no remediation plan has yet been
approved. No amounts have been accrued for this potential liability. Furthermore, to the extent Plum Creek is required to indemnify Georgia-Pacific for its share of the remediation costs, Plum Creek may be able to recover a portion of its cost from
Georgia-Pacifics insurance policy, or indemnity obligations of the various lessees that conducted mining operations on the property, or both.

Unrecorded Contingencies.The company believes it will be successful in defending the Property Damage Litigations and the
Arkansas Environmental Issue. However, if the company is not successful in defending these claims, we believe the aggregate combined losses for the Property Damage Litigations and Arkansas Environmental Issue would range between $0 and $4 million.
Other than the Property Damage Litigations and the Arkansas Environmental Issue, management currently believes that resolving pending legal proceedings against the company, individually or in aggregate, will not have a material adverse impact on our
financial position or results of operations. However, these matters are subject to inherent uncertainties and managements view on these matters may change in the future. Were an unfavorable final outcome in one or multiple legal proceedings to
occur, there exists the possibility of a material adverse impact on our financial position and the results of operations for the period in which any unfavorable outcome becomes reasonably estimable.

Contractual Obligations.The company has contracted
to source logs and supply fiber with customers under long-term agreements at prevailing market rates. The agreements expire beginning in 2007 through 2023, with various renewal options by either party for periods ranging from three years to 15
additional years.

Lease Commitments.The company leases buildings and equipment under noncancelable operating lease agreements. Operating lease expense was $7 million in 2006,
$5 million in 2005 and $3 million in 2004. The company leases certain timberlands in which the company acquired title to the standing timber at the inception of the lease. The following summarizes the future minimum operating lease payments and
obligations in connection with leasing timberlands at December 31, 2006 (in millions):

NOTE 14. SEGMENT INFORMATION

The company is organized into nine business units on the basis of both product line and geographic region. Each business unit has a separate management team due to geographic location, marketing strategies and/or
production processes. In applying SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information, these business units have been aggregated into five reportable segments based on similar long-term economic
characteristics. The companys reportable segments are: (1) Northern Resources, (2) Southern Resources, (3) Real Estate, (4) Manufactured Products and (5) Other.

Northern Resources Segment. The Northwest Resource region
and the Northeast Resource region are aggregated into the Northern Resources Segment. The Northern Resources Segment consists of timberlands located in Maine, Michigan, Montana, New Hampshire, Oregon, Washington, West Virginia and Wisconsin. The
Northern Resources Segment grows timber for sale primarily in domestic regional markets. Additionally, some logs are sold in export markets, mainly Canada. The Northern Resources Segment sells softwood and hardwood sawlogs and softwood and hardwood
pulpwood. Softwood sawlogs are sold to regional lumber and plywood manufacturers. Logs harvested in Montana are sold mostly to our lumber and plywood mills (which are part of the Manufactured Products Segment). Hardwood sawlogs are sold primarily to
furniture manufacturers. Softwood and hardwood pulpwood is sold to regional paper and packaging manufacturers.

Southern Resources Segment.The Gulf South Resource region and the Atlantic South Resource region are aggregated into the Southern Resources Segment. The Southern
Resources Segment consists of timberlands located in Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina and Texas. The Southern Resources Segment grows timber for sale in domestic regional markets.
The Southern Resources Segment sells primarily softwood sawlogs and pulpwood. Softwood sawlogs are sold to regional lumber and plywood manufacturers. Softwood pulpwood is sold to regional paper and packaging manufacturers. Additionally, the Southern
Resources Segment leases our timberlands to third parties on an annual basis for recreational purposes.

Real Estate Segment.The Real Estate Segment consists of sales of higher and better use timberlands and sales of non-strategic timberlands. We estimate that included
in our approximately 8.2 million acres of timberlands are about 1.7 million acres of higher and better use timberlands, which are expected to be sold and/or developed over the next 15 years for residential, recreational or conservation
purposes. In addition, the company has approximately 400,000 acres of non-strategic timberlands, which are expected to be sold over the next five years. In the meantime, these timberlands continue

to be used productively in our business of growing and selling timber. Included within the 1.7 million acres of higher and better use timberlands are
approximately 225,000 acres that will be developed by the companys wholly-owned taxable REIT subsidiaries. Properties developed internally by the company will generally be low-intensity development limited to obtaining entitlements and
investing in infrastructures such as roads and utilities. Larger and more complicated projects, such as destination resorts and master planned communities, will be developed through joint venture arrangements in which we are the minority partner and
our involvement is limited to selling and/or contributing timberlands and exercising certain protective rights.

Manufactured Products Segment. The lumber, plywood and medium density fiberboard (MDF) businesses are aggregated into the Manufactured Products Segment. The Manufactured
Products Segment consists of four lumber mills, two plywood mills, two MDF facilities, one lumber remanufacturing facility in Montana, and one lumber remanufacturing facility in Idaho. The lumber facilities produce boards, studs, and dimension
lumber and the panel facilities produce high-quality plywood and MDF panels. All of these products are targeted to domestic lumber retailers, home construction, industrial customers, and to a lesser extent, for export primarily to Canada. Residual
chips that are not used internally are sold to regional pulp and paper manufacturers. Revenues from manufactured products by product line were as follows for the years ended December 31 (in millions):



|        |  |      |     |      |   |      |  |   |

|       
|       

Other Segment. The Other Segment consists primarily of income associated with mineral extraction, natural gas production and communication and transportation rights of way. Mineral income consists of royalty revenue from the extraction of oil and
gas, natural aggregates and coal (until the first quarter of 2005).

In the fourth quarter of 2004, Plum Creek sold certain subsurface property rights
(primarily coal reserves, excluding coalbed methane, oil and gas reserves) in Buchanan County, Virginia, to Consol Energy, Inc. The company received proceeds of $23 million in connection with the sale and the release of certain legal claims,
which the company believes comprised a portion of the proceeds. However, the sale agreement did not specify an allocation. The net gain from this sale and settlement of certain legal claims, after reducing the proceeds for applicable income taxes,
was $23 million. During the first quarter of 2005, we sold our remaining coal reserves for proceeds of $21 million. The net gain from this sale after reducing the proceeds for our book basis and applicable income tax, was $20 million. Prior to
these sales, substantially all of the coal reserves were subject to long-term mineral leases. For the year ended December 31, 2004, the Other Segment revenues and operating income included approximately $1 million from royalties associated with
the mineral leases, and less than $1 million in 2005. These gains have been reported in our Consolidated Statements of Income as a separate line item below Income from Continuing Operations.

The company evaluates performance and allocates capital to the segments based on operating income before interest, unallocated corporate expenses and taxes. Asset
information is not reported by segment, as the company does not produce such information internally.

|D | Plum Creek had been a party to a joint operating agreement with Geomet, Inc., a coalbed methane developer, with whom the company had jointly explored for and
developed coalbed methane gas found on certain of its timberlands in West Virginia and Virginia. During the second quarter of 2004, the company sold its working interest in the joint operating agreement to Geomet, Inc. for $27 million. The
resulting gain of $5 million before income taxes is included in Other Operating Income (Expense), net in our operating income for 2004. The agreement provides for contingent additional sales proceeds of up to $3 million payable at the end of
2007. The impact on operating income from our working interest in the joint operating agreement during the year ended December 31, 2004 was less than $1 million.

REPORT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Plum Creek Timber Company, Inc.

We have audited the accompanying consolidated balance sheets of Plum Creek Timber Company,
Inc. as of December 31, 2006 and 2005, and the related consolidated statements of income, stockholders equity, and cash flows for each of the three years in the period ended December 31, 2006. These financial statements are the
responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We
conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Plum Creek Timber Company, Inc. at December 31, 2006 and 2005, and the consolidated results of
its operations and its cash flows for each of the three years in the period ended December 31, 2006, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Plum Creek Timber Company, Inc.s internal control over financial
reporting as of December 31, 2006, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 16, 2007 expressed an
unqualified opinion thereon.

As discussed in Note 1 to the consolidated financial statements, in 2006 the Company changed its method of accounting for
share-based payments and also changed its method of accounting for its defined benefit pension plan.

Plum Creek Timberlands, L.P.

Notes to
Consolidated Financial Statements

NOTE 1. ACCOUNTING POLICIES

General.Plum Creek Timberlands, L.P. is a Delaware Limited Partnership and a wholly-owned subsidiary of Plum Creek Timber
Company, Inc. Plum Creek Timber Company, Inc. (Parent) is a Delaware Corporation and real estate investment trust, or REIT. References herein to the Operating Partnership, we, us or
our relate to Plum Creek Timberlands, L.P. and all of its wholly-owned consolidated subsidiaries; references to Plum Creek relate to Plum Creek Timber Company, Inc. and all of its wholly-owned subsidiaries.

At December 31, 2006, the Operating Partnership owned and managed approximately 8.2 million acres of timberlands in the Northwest, Southern and Northeast United
States, and owned and operated ten wood product conversion facilities in the Northwest United States. Included in the 8.2 million acres are about 1.7 million acres of higher and better use timberlands, which are expected to be sold and/or
developed over the next 15 years for residential, recreational or conservation purposes. In addition, the Operating Partnership has approximately 400,000 acres of non-strategic timberlands, which are expected to be sold over the next five years. In
the meantime, these timberlands continue to be used productively in our business of growing and selling timber.

Basis of Presentation.The consolidated financial statements of the Operating Partnership include the accounts of Plum Creek Timberlands, L.P. and its subsidiaries.
The Operating Partnership is 100% owned by Plum Creek Timber Company, Inc. Plum Creek Timber Company, Inc. has no independent assets or liabilities. Plum Creek Timber Company, Inc. has no operations other than its investment in Plum Creek
Timberlands, L.P. and transactions in its own equity, such as the issuance and/or repurchase of common stock and the receipt of proceeds from stock option exercises. Intercompany transactions and accounts between Plum Creek Timberlands, L.P. and its
subsidiaries have been eliminated in consolidation. All transactions are denominated in United States dollars.

Use of Estimates.The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

Business
Concentrations.Sales of the Operating Partnerships products are dependent upon the economic conditions of the housing, repair and remodeling, industrial, and pulp and paper
industries. Changes in these industries may significantly affect managements estimates and the Operating Partnerships performance.

Revenue Recognition.Timber sales revenues are recognized when legal ownership and the risk of loss transfers to the purchaser and the quantity
sold is determinable. The Operating Partnership sells timber under delivered log agreements as well as through sales of standing timber (or stumpage). For delivered sales, revenue which includes amounts billed for shipping and handling
(logging and hauling of timber), is recognized when the log is delivered to the customer. Stumpage is sold using primarily pay-as-cut or lump-sum sale agreements. Under a pay-as-cut contract, the purchaser acquires the right to harvest specified
timber on a tract, at an agreed upon price per unit. The sale and any related advances are recognized as revenue as the purchaser harvests the timber on the tract. Under a lump-sum sale, the parties agree to a purchase price for all the timber
available for harvest on a tract of land. Generally, the purchase 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. Therefore, revenue under a lump-sum sale is
recognized each month based on the timber harvested compared to the total estimated timber available to be harvested based on the timber cruise over the term of the contract (usually 12 to 18 months). An adjustment may be required to the extent the
actual timber harvested is different than the estimate of timber available.

Revenues generated from the sale of lumber, plywood, medium density fiberboard
(MDF) and related by-products, primarily wood chips, and amounts billed for shipping and handling, are recognized at the time of delivery. Revenues

NOTES TO
CONSOLIDATED FINANCIAL STATEMENTS (continued)



generated from real estate sales include the sale of higher and better use timberlands and non-strategic timberlands. In some of these transactions, the
Operating Partnership sold timberlands that qualified for like-kind (tax-deferred) exchange treatment under the Internal Revenue Code. Substantially all of these sales involved a third party intermediary, whereby the third party intermediary
received proceeds related to the property sold and then reinvested the proceeds in like-kind property. The proceeds are recorded as revenue when the third party intermediary receives them.

Revenue from real estate sales is recognized in accordance with Statement of Financial Accounting Standards (SFAS) No. 66, Accounting for Sales of
Real Estate. For substantially all of the Operating Partnerships real estate sales, we receive the entire consideration in cash at closing (Cash Sales). Also at closing, the risks and rewards of ownership transfer to the buyer
and we do not have a continuing involvement in our properties after they are sold. The Operating Partnership recognizes revenue under the full accrual method for Cash Sales of real estate when the sale is consummated (i.e., at closing). On occasion
the Operating Partnership receives a portion of the real estate sale consideration in the form of a note receivable. Such sales represented less than 2% of our revenue from real estate sales for each of the years in the three-year period ended
December 31, 2006. Under these circumstances, we use the full accrual method of recognizing revenue if the buyers initial and continuing investment is adequate; otherwise, revenue is generally recognized under the cost recovery method or
deposit method, depending on the circumstances. Furthermore, the Operating Partnership may occasionally sell timberlands to a single buyer under a multi-period contract covering a series of prescheduled closings and/or options. Under these
multi-period contracts, once title and risk of loss have transferred to the buyer for individual properties, the properties sold cannot be returned for a refund. However, deposits for future closings under multi-period contracts may be refunded
under certain circumstances. The Operating Partnership treats each closing under a multi-period arrangement as a separate sale and recognizes revenue in accordance with Emerging Issues Task Force (EITF) No. 00-21, Revenue Arrangements
with Multiple Deliverables. Broker commissions and closing costs of our Real Estate Segment are included in Cost of Goods Sold.

Revenue from
development projects is generally recognized under the full accrual method of accounting because sales generally do not commence until the project is completed. On occasion, revenue from development projects will be recognized under the percentage
of completion method when properties are sold prior to their completion. Less than 5% of our development projects sales during 2006 were sold prior to completion of the project.

Cash and Cash Equivalents.All highly liquid investments purchased with an original maturity of
three months or less are considered to be cash equivalents. Substantially all of the cash and cash equivalents are invested in money market funds. The Operating Partnership periodically reviews the credit rating of the financial institution where
the money market funds are maintained. Additionally, the Operating Partnership considers certain proceeds held in escrow associated with like-kind exchanges as cash equivalents. See Like-Kind Exchanges.

Restricted Cash.The Operating Partnership has restricted
cash related to certain advances from a customer associated with lump-sum timber sales. The Operating Partnership reports this cash as Restricted Advance from Customer until the timber associated with the lump-sum contract is harvested.

Accounts Receivable.Accounts
receivable at December 31, 2006 and 2005, is presented net of an allowance for doubtful accounts of $0.6 million and $0.5 million, respectively. Accounts are deemed past due based on payment terms. The allowance for doubtful accounts
represents managements estimate and is based on historical losses, recent collection history, credit ratings of individual customers and existing economic conditions. Delinquent accounts are charged against the allowance for doubtful accounts
to the extent and at the time they are deemed uncollectible.

Like-Kind Exchanges.The Operating Partnership enters into like-kind (tax-deferred) exchange transactions to acquire and sell assets, principally timberlands. These transactions include both forward (timberlands
sold, followed by reinvestment of proceeds to acquire timberlands) and reverse (timberlands purchased, followed by receipt of proceeds from timberland sales) like-kind exchanges. The Operating Partnership uses a qualified escrow account to
facilitate like-kind exchange transactions. Funds from forward like-kind exchange transactions are included as a current asset under the description Like-Kind Exchange Funds Held in Escrow because the funds are restricted from being used until the
funds are either successfully

reinvested in timber and timberlands or the exchange fails and the proceeds are distributed to the Operating Partnership. Escrow funds held in connection
with reverse like-kind exchange transactions are included in Cash and Cash Equivalents because these funds are available upon demand and are not subject to risk of loss. At December 31, 2006 and 2005, there was $29 million and $7 million of
cash from reverse like-kind exchange transactions included in Cash and Cash Equivalents, respectively.

Inventories.Logs, work-in-process and finished goods are stated at the lower of cost or market using the average cost method. Supplies inventories are stated at cost.
Costs for manufactured inventories included raw materials, labor, supplies, energy, depreciation and production overhead. Cost of log inventories included timber depletion, stumpage, associated logging and harvesting costs, road costs and production
overhead.

Inventories, accounted for using the lower of average cost or market, consisted of the following (in millions):

Timber and Timberlands.Timber and timberlands, including logging roads, are stated at cost less accumulated depletion for timber previously harvested and accumulated road amortization. The Operating Partnership capitalizes timber and timberland
purchases and reforestation costs and other costs associated with the planting and growing of timber, such as site preparation, growing or purchases of seedlings, planting, fertilization, herbicide application and the thinning of tree stands to
improve growth. Timber carrying costs, such as real estate taxes, insect control, wildlife control, leases of timberlands (other than lease payments for the purchase of standing timber, in which case the payments are capitalized) and forest
management personnel salaries and fringe benefits, are expensed as incurred. Costs of major roads are capitalized and amortized over 30 years. Costs for roads that are built to access multiple logging sites over numerous years are capitalized and
amortized over six years. Costs for roads built to access a single logging site are expensed as incurred.

Costs attributable to timber harvested, or
depletion, are charged against income as trees are harvested. Depletion rates are determined annually based on the relationship between net carrying value of the timber plus certain capitalizable silviculture costs expected to be incurred over the
harvest cycle and total timber volume estimated to be available over the harvest cycle. The depletion rate does not include an estimate for either future reforestation costs associated with a stands final harvest or future volume in connection
with the replanting of a stand subsequent to its final harvest. Net carrying value of the timber and timberlands is used to compute the gain or loss in connection with timberland sales. No book basis is allocated to the sale of conservation
easements.

Higher and Better Use Timberlands / Real Estate Development.At December 31, 2006, the Operating Partnership owned 8.2 million acres of timberlands, of which approximately 1.7 million acres are higher and better use timberlands, which are
expected to be sold and/or developed over approximately the next 15 years. Prior to the sale and/or development of these acres, these timberlands will be used productively in our business of growing and selling timber.

Properties developed internally (Internal Development) will generally be low-intensity development limited to activities associated with obtaining
entitlements and investing in infrastructure, such as roads and utilities. Larger and more complicated projects, such as destination resorts and master planned communities, will be developed through joint venture arrangements in which we are the
minority partner and our involvement is limited to selling and/or contributing land and exercising certain protective rights (External Development).

Costs associated with a specific
real estate project are capitalized once we determine that the project is viable. Both external and internal costs directly associated with the specific real estate project are capitalized. We capitalize improvements and other development costs,
including interest costs and property taxes, during the development period (capitalized interest and property taxes were less than $1 million in 2006 and 2005). General real estate development costs not related to a specific project and costs
incurred before management has concluded that a project will be successful (e.g. investigatory costs) are expensed as incurred. For real estate projects with multiple parcels, we determine the cost of the individual lots sold by allocating the
historical cost of the land, timber, development and common construction costs on a relative sales value.

Capitalized costs (including our book basis in
the related timber and timberlands) associated with Internal Developments were $14 million at December 31, 2006. The portion of the capitalized costs related to Internal Development properties that are expected to be sold within the next year
($3 million) is presented in the Consolidated Balance Sheet at December 31, 2006, as Real Estate Development Properties. The portion that is expected to be sold beyond one year ($11 million) is included in Other Assets. Total capitalized real
estate development costs (including our book basis in the related timber and timberlands) at December 31, 2005 were $31 million, including $5 million included within Other Assets.

The book basis of higher and better use timberlands that are considered held for sale in accordance with Statement of Financial Accounting Standard No. 144, Accounting for the Impairment or Disposal of
Long-Lived Assets (SFAS No. 144), are presented in the Consolidated Balance Sheet as Assets Held for Sale. Total assets held for sale were $82 million at December 31, 2006 and $43 million at December 31, 2005.
Generally, timberlands that are under contract to sell or are listed for sale through an independent broker or through a wholly-owned taxable REIT subsidiary and are expected to be sold within the next year are considered assets held for sale. The
book basis of higher and better use timberlands that do not meet the criteria of SFAS No. 144 are included in Timber and Timberlands. Capitalized costs (including our book basis in the related timber and timberlands) associated with External
Development properties are presented in the Consolidated Balance Sheet as Assets Held for Sale if they are expected to be sold to a joint venture within the next year. External Development properties that are not expected to be sold to a joint
venture within the next year are included in Timber and Timberlands.

Property, Plant and
Equipment.Property, plant and equipment are recorded at cost. Replacements of major units of property are capitalized, and the replaced units are retired. Replacement of minor
components of property and repair and maintenance costs are charged to expense as incurred.

All property, plant and equipment other than manufacturing
machinery (lumber, plywood and MDF) are depreciated using the straight-line method over the estimated useful lives of the related assets. Manufacturing machinery and equipment are depreciated on a units-of-production basis, which approximates a
straight-line basis. Useful lives are 25 years for land improvements, 20 to 45 years for buildings, and 3 to 20 years for machinery and equipment. Leasehold improvements are depreciated over the lease term or estimated useful life, whichever is
shorter. The cost and related accumulated depreciation of property sold or retired are removed from the accounts and any gain or loss is recorded.

Grantor Trusts.The Operating Partnership has a grantor trust that was established for deferred compensation and deferred
Plum Creek shares. See Note 5 of the Notes to Financial Statements. Deferred compensation assets, which include money market and mutual fund investments, are classified as trading securities and are carried at market value. Realized
gains and losses and changes in unrealized gains and losses and a corresponding amount of compensation expense are recorded in the Consolidated Statements of Income.

The Operating Partnership maintains another grantor trust, which the Operating Partnership uses to fund its non-qualified pension plan obligation. See Note 7 of the Notes to Financial Statements. Money market and
mutual fund investments held by this trust are classified as available for sale securities. The investments are carried at market values on the Operating Partnerships Consolidated Balance Sheet; realized gains and losses are
recognized in the Consolidated Statements of Income; changes in unrealized gains and losses are recorded as other comprehensive income or loss.

Shipping and Handling Costs.Costs incurred for shipping timber and manufactured products are included in cost of goods
sold.

Accounting for Share-Based Compensation.In December of 2004, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards
No. 123 (revised 2004), Share-Based Payment (SFAS No. 123(R)), which is a revision of SFAS No. 123, Accounting for Stock-Based Compensation. SFAS No. 123(R) supersedes Accounting Principles
Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and amends SFAS No. 95, Statement of Cash Flows. Generally, the approach in SFAS No. 123(R) is similar to the approach described in SFAS
No. 123. However, SFAS No. 123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. We adopted SFAS No. 123(R) on
January 1, 2006, using the modified-prospective transition method. Results for prior periods have not been restated, as provided for under the modified-prospective method.

Previously, the Operating Partnership adopted the fair-value-based method of accounting for share-based payments effective January 1, 2002, using the prospective method described in SFAS No. 148,
Accounting for Stock-Based CompensationTransition and Disclosure. Beginning January 1, 2002, the Operating Partnership used the Black-Scholes-Merton formula to estimate the value of stock options granted to employees and will
continue to use this option valuation model under SFAS No. 123(R). The Operating Partnership does not expect the expense for stock options computed in accordance with SFAS No. 123(R) to be materially different than the expense previously
computed under SFAS No. 123.

In addition to stock options, Plum Creek also grants restricted stock and restricted stock units of Plum Creek Timber
Company, Inc., value management awards and dividend equivalents, a portion of which may be payable in common stock of Plum Creek Timber Company, Inc. Grants of both value management awards and dividend equivalents represent awards that are
classified and accounted for as liabilities under SFAS No. 123(R). As a result, the expense recognized over the performance period for both value management awards and dividend equivalents will equal the fair value of an award as of the last
day of the performance period multiplied by the number of awards that are earned. Furthermore, SFAS No. 123(R) requires the quarterly expense recognized during the performance period to be based on the fair value of value management awards and
dividend equivalents as of the end of the most recent quarter. The Operating Partnership does not expect the total expense recognized over the performance period for value management awards and dividend equivalents computed in accordance with SFAS
No. 123(R) to be materially different than the total expense computed under SFAS No. 123. However, as a result of the requirement under SFAS No. 123(R) to base the quarterly expense on the current fair value of value management awards
and dividend equivalents, the quarterly and annual expense recognized under SFAS No. 123(R) could be materially different than the quarterly and annual expense we previously recognized under SFAS No. 123.

The adoption of SFAS No. 123(R) resulted in a cumulative benefit from an accounting change in the Consolidated Statements of Income of $2 million, net of tax, for
the year ended December 31, 2006. The cumulative effect adjustment is primarily a result of changes in expense related to the fair value of the value management awards and dividend equivalents.

SFAS No. 123(R) also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an
operating cash flow as required under previous literature. This requirement will reduce net operating cash flows and increase net financing cash flows in periods after adoption. The impact of this change on net operating cash flows and net financing
cash flows for the year ended December 31, 2006, was less than $1 million.

Excluding the cumulative effect of the accounting change of $2 million, net
of tax, the impact of adopting SFAS No. 123(R) on January 1, 2006 was an increase of less than $1 million to our income before income taxes, income from continuing operations, and net income for the year ended December 31, 2006 than
if we had continued to account for share-based compensation in accordance with SFAS No. 123.

Other
Operating Income.Since 2000, the Operating Partnership has been a member of an industry coalition alleging that lumber exports to the U.S. were unfairly subsidized. This dispute was
resolved during 2006, and Plum Creek received a settlement of $14 million ($13 million net of tax). The settlement is presented in our Consolidated Statements of Income as Gain from Canadian Lumber Settlement.

Periodically the Operating
Partnership will recognize gains and losses from miscellaneous asset sales and litigation settlements. Gains recognized for 2006, 2005 and 2004 were $4 million, $5 million and $5 million, respectively, and were reported in our Consolidated
Statements of Income as Other Operating Income (Expense), net.

Reclassifications.Certain prior year amounts have been reclassified to conform to the 2006 presentation. The reclassifications had no impact on operating income or net income.

For segment information, certain direct segment costs, previously included in corporate and other unallocated expense were reclassified in 2005 and 2004 to conform to the
2006 presentation (see Note 12 of the Notes to Financial Statements).

Capitalized costs associated with Internal Developments are separately stated at
December 31, 2006. Previously, these costs were included in Timber and Timberlands. Accordingly, $31 million was reclassified at December 31, 2005 from Timber and Timberlands.

The book basis of higher and better use timberlands that are held for sale are separately stated at December 31, 2006. Previously, the book basis of assets held for sale were included in Timber and Timberlands.
Accordingly, $43 million was reclassified at December 31, 2005 from Timber and Timberlands.

New Accounting Pronouncements

SFAS No. 158.In September 2006, the Financial
Accounting Standards Board issued Statement of Financial Accounting Standards No. 158, Employers Accounting for Defined Benefit Pension and Other Post Retirement Plansan amendment of FASB Statements No. 87, 88, 106, and
132(R)(SFAS No. 158). SFAS No. 158 requires entities to recognize the funded status of their defined benefit pension plans in the balance sheet, measured as the difference between the fair value of the plan assets less the
projected benefit obligation. Any resulting asset or liability will be fully recognized in the balance sheet. SFAS No. 158 also requires the actuarial measurement date to be at the end of the entitys fiscal year and expanded disclosure in
the footnotes to the financial statements. SFAS No. 158 is effective for fiscal years ending after December 15, 2006 for entities with publicly traded equity securities, and requires prospective application, with the initial recognition of
the funded status being recognized as a component of accumulated other comprehensive income (loss). The Operating Partnership adopted SFAS No. 158 on December 31, 2006. As a result of adopting SFAS No. 158, the Operating Partnership
recorded a $14 million decrease in accumulated other comprehensive income (loss), net of tax of $5 million. See Note 7 of the Notes to Financial Statements.

SAB 108.In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 108, Considering
the effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements(SAB 108), which provides interpretive guidance on the consideration of the effects of prior year misstatements in
quantifying current year misstatements for the purpose of a materiality assessment. SAB 108 is effective for fiscal years ending after November 15, 2006. The adoption of this standard at December 31, 2006 did not have an impact on the
Operating Partnerships financial condition, results of operations or cash flows.

SFAS
No. 157.In September 2006, the FASB issued SFAS No. 157, Fair Value Measurement (SFAS No. 157). SFAS No. 157 defines fair value, establishes a framework
for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements, but does not require any new fair value measurements. SFAS No. 157 is effective for fiscal years beginning after
November 15, 2007 and interim periods within those fiscal years. The Operating Partnership will adopt SFAS No. 157 in the first quarter of 2008. The Operating Partnership is in the process of determining the effect, if any, the adoption of
SFAS No. 157 will have on the consolidated financial statements.

FIN 48.In July 2006, the Financial Accounting Standards Board issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes(FIN 48). In summary, FIN 48
requires that all tax positions subject to Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes, be analyzed using a two-step approach. The first step requires an entity to determine if a tax position is
more-likely-than-not to be sustained upon examination. In the second step, the tax

benefit is measured as the largest amount of benefit, determined on a cumulative probability basis that is more-likely-than-not to be realized upon ultimate
settlement. FIN 48 is effective for fiscal years beginning after December 15, 2006, with any adjustment in a companys tax provision being accounted for as a cumulative effect of accounting change in beginning equity. The Operating
Partnership adopted FIN 48 on January 1, 2007. The adoption of this standard did not have an impact on the Operating Partnerships financial condition, results of operations or cash flows.

During 2006, the Operating Partnership acquired approximately 98,000 acres of timberlands primarily located in
Oregon for $111 million. These purchases were financed primarily by using the funds from tax-deferred exchanges and our line of credit, and have been accounted for as asset acquisitions. Timberland dispositions during 2006 were approximately 112,000
acres, of which 57,000 acres were located in the Northern Resources Segment and 55,000 acres were located in the Southern Resources Segment.

During 2005,
the Operating Partnership acquired approximately 754,000 acres of timberlands located in Northern Michigan, Arkansas and Florida for $501 million. These purchases were financed primarily by using proceeds from the issuance of debt and funds from
tax-deferred exchanges and have been accounted for as asset acquisitions. Timberland dispositions during 2005 were approximately 232,000 acres, of which 63,000 acres were located in the Northern Resources Segment and 169,000 acres were located in
the Southern Resources Segment.

During 2005, the Operating Partnership sold certain subsurface property rights (its remaining coal reserves,
excluding coalbed methane, oil and gas reserves) in Buchanan County, Virginia. The sale of these properties is reflected in our Consolidated Statements of Income as Gain on Sale of Properties, net of tax. For the year ended December 31, 2005,
we received sales proceeds of $21 million and, after deducting our book basis of $1 million, recorded a gain of $20 million. See Note 12 of the Notes to Financial Statements.

The Operating Partnerships Real Estate Segment consists of sales of higher and better use timberlands and sales of non-strategic timberland. Occasionally, non-strategic timberlands are sold at a loss. Each real
estate sale is evaluated for a potential impairment in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. During 2006, the Operating Partnership recorded impairment losses of $2 million in
connection with the potential sale of non-strategic timberlands, which had a book basis of $5 million. During 2005, the Operating Partnership recorded impairment losses of $1 million in connection with the potential sale of non-strategic
timberlands, which had a book basis of $4 million. During 2004, the Operating Partnership recorded impairment losses of $21 million in connection with the potential sale of non-strategic timberlands, which had a book basis of $45 million;
substantially all of these properties were sold during 2004. The impairment losses are included in Cost of Goods Sold for Real Estate in our Consolidated Statements of Income.

During 2005, the Operating Partnerships Southern Resources Segment recognized a $2 million loss, representing the book basis of the timber volume destroyed as a result of severe winds from Hurricane Katrina on
approximately 350,000 acres in Mississippi.

During the fourth quarter of 2004, the Operating Partnership concluded it had excess production capacity at one of
its mills; and therefore, concluded that the mills long-lived assets were impaired. The Operating Partnership recorded an impairment loss of $9 million during the fourth quarter of 2004 by writing the carrying value of the mills
long-lived assets of $14 million down to their estimated fair value of $5 million. The impairment loss of $9 million is reflected in the operating income of our Manufactured Products Segment and included in Cost of Goods Sold for Manufacturing
in our Consolidated Statements of Income. The estimated fair value was computed based on expected future cash flows discounted at the risk-free rate of interest.

The Operating Partnership had been a party to a joint operating agreement with Geomet, Inc., a coalbed methane developer, with whom the Operating Partnership jointly explored for and developed coalbed methane gas found on certain of the
Operating Partnerships timberlands in West Virginia and Virginia. During 2004, the Operating Partnership sold its working interest in the joint operating agreement to Geomet, Inc. See Note 12 of the Notes to Financial Statements.

NOTE 3. INCOME TAXES

Plum Creek Timberlands, L.P. is a
limited partnership and therefore, not subject to income tax. Plum Creek Timberlands, L.P.s taxable income is allocated 100% to its parent, Plum Creek Timber Company, Inc., which has elected to be taxed as a REIT under sections 856-860 of the
United States Internal Revenue Code. A REIT is generally not subject to corporate-level income tax if it distributes 100% of its taxable income to shareholders and satisfies other organizational and operational requirements as set forth in the
Internal Revenue Code. However, the Operating Partnership conducts certain non-REIT activities through various wholly-owned taxable REIT subsidiaries, which are subject to corporate-level income tax. These activities include our manufacturing
operations, the harvesting and sale of logs, and the development and/or sale of some higher and better use timberlands. The Operating Partnerships tax provision includes the tax expense and/or benefit associated with Plum Creeks
wholly-owned taxable REIT subsidiaries, as well as any tax expense and/or benefit incurred by the REIT. The effective tax rate for the Operating Partnership is lower that the federal corporate statutory rate primarily due to Plum Creeks status
as a REIT. If a company fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four
subsequent taxable years.

The book basis of the Operating Partnerships assets and liabilities exceeds its tax basis by approximately $2.3 billion at
December 31, 2006. Plum Creeks wholly-owned taxable REIT subsidiaries file a consolidated federal income tax return.

As a consequence of the
October 6, 2001 merger with The Timber Company, which involved merging a taxable entity into a nontaxable entity, Plum Creek will generally be subject to corporate-level tax (built-in gains tax) if Plum Creek makes a taxable disposition of
certain property acquired in the merger with The Timber Company within the ten-year period following the merger date. The built-in gains tax applies to gains from such asset sales to the extent that the fair value of the property exceeds its tax
basis at the merger date. Built-in gains tax is generally not payable on dispositions of property to the extent the proceeds from such dispositions are reinvested in qualifying like-kind replacement property. The built-in gains tax does not apply to
income generated from the harvesting and sale of timber.

PLUM CREEK TIMBERLANDS, L.P.

NOTES TO
CONSOLIDATED FINANCIAL STATEMENTS (continued)



In connection with our merger
with The Timber Company, Plum Creek wrote-off all of The Timber Companys deferred income tax liability related to timber and timberlands except for $11 million. The $11 million deferred income tax liability related to the book-tax basis
difference of timber and timberlands that were expected to be sold, and subject to, the built-in gains tax during the ten-year period ending October 6, 2011. During the period October 6, 2001 to December 31, 2006, the $11 million
deferred income tax liability was reduced by $1 million due to the payment of tax in connection with sales of timberlands subject to the built-in gains tax.

In accordance with Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes,Plum Creek remeasures the amount of deferred income taxes needed in connection with expected sales of timberlands subject to
the built-in gains tax each quarterly reporting period. In 2005, Plum Creek reduced our deferred tax liability associated with timber and timberlands by $5 million and correspondingly recorded a deferred tax benefit of $5 million. Based on projected
timberland sales subject to the built-in gains tax for the period December 31, 2006 to October 6, 2011, and Plum Creeks ability to successfully reinvest proceeds in like-kind properties, it is estimated Plum Creek needs a deferred
tax liability of approximately $5 million. As a result, no adjustment to the deferred tax liability associated with built-in gains tax was made in 2006.

Plum Creek conducts certain non-REIT activities through various wholly-owned taxable REIT subsidiaries, which are subject to corporate-level income tax. These activities include the Operating Partnerships manufacturing operations, the
harvesting and sale of logs, and the development and/or sale of some of the Operating Partnerships higher and better use timberlands.

The provision
for income taxes consists of the following for theyears ended December 31(in millions):

Plum Creek filed its federal income tax return as part of
Georgia-Pacifics consolidated income tax return for all tax years through the date of the merger with The Timber Company on October 6, 2001. Under the agreement governing the terms of the merger with The Timber Company, Plum Creek remains
liable to Georgia-Pacific for any additional tax that would result from audit adjustments by the Internal Revenue Service (the Service) and by state and local taxing authorities. The Service has completed all examinations of
Georgia-Pacifics consolidated income tax returns through 2000. Georgia-Pacifics consolidated income tax return for 2001 is currently under examination. Additionally, the Service has completed examinations of the federal income tax return
of Plum Creek Timber Company, Inc. and the consolidated federal income tax return of the taxable REIT subsidiaries for the year 2003. Plum Creek has no open tax years prior to 2003.

On June 29, 2006, the Operating Partnership terminated its previous $650 million revolving line of credit
maturing in January 2009 and entered into a new $750 million revolving line of credit agreement that matures in June 2011. The revolving line of credit may be increased to $1 billion subject to certain terms and conditions. As of December 31,
2006, the weighted-average interest rate for the borrowings on the line of credit was 5.79%. The interest rate on the line of credit is based on LIBOR plus 0.425%. This rate can range from LIBOR plus 0.27% to LIBOR plus 1% depending on our debt
ratings. Subject to customary covenants, the line of credit allows for borrowings from time to time up to $750 million, including up to $100 million of standby letters of credit. Borrowings on the line of credit fluctuate daily based on cash needs.
As of December 31, 2006, we had $581 million of borrowings and $5 million of standby letters of credit outstanding; $164 million remained available for borrowing under our line of credit. As of January 5, 2007, $243 million
of the borrowings under our line of credit was repaid.

In April 2006, Plum Creek filed with the Securities and Exchange Commission a shelf registration
statement under which Plum Creek Timber Company, Inc., from time to time, may offer and sell any combination of preferred stock, common stock, depositary shares, warrants and guarantees, and under which Plum Creek Timberlands, L.P., may from time to
time, offer and sell debt securities. The shelf registration statement expires on April 25, 2009.

On May 2, 2006, the Operating Partnership.,
issued off the shelf registration statement $225 million aggregate principal amount of its senior notes with a coupon rate of 5.875%, at a market price of 96.686% of the principal amount. The net proceeds of $216 million were used primarily to repay
outstanding debt maturing during 2006. The notes mature in 2015 and are fully and unconditionally guaranteed by Plum Creek Timber Company, Inc.

In May of
2005, the Operating Partnership entered into a $50 million one-year term loan agreement to finance the acquisition of approximately 35,000 acres of Florida timberlands. This loan was repaid in May of 2006.

In November of 2005, the
Operating Partnership issued $300 million aggregate principal amount of its senior notes with a coupon rate of 5.875% at a market price of 99.731% of the principal amount, maturing in 2015. The net proceeds of $297 million were used primarily to
purchase timberlands. The Senior Notes due 2015 are fully and unconditionally guaranteed by Plum Creek Timber Company, Inc.

During 2006, the Operating
Partnership made debt principal payments totaling $207 million. During 2005, the Operating Partnership made debt principal payments totaling $47 million.

The senior notes are structurally subordinated to all unsecured debt and liabilities of the Operating Partnerships subsidiaries, and junior in right of payment to secured debt of the Operating Partnerships subsidiaries to the
extent of the value of the assets secured by such debt. At December 31, 2006, the total amount of unsecured debt and liabilities of the Operating Partnerships subsidiaries was approximately $859 million, and the total amount of secured
debt of the Operating Partnerships subsidiaries was approximately $13 million, representing mortgage notes secured by certain manufacturing assets. In the event of insolvency, bankruptcy, liquidation, reorganization, dissolution, winding up of
the Operating Partnerships business or other similar process, the assets of the Operating Partnerships subsidiaries will be available to pay the amounts due on the senior notes only after the secured and unsecured indebtedness of the
Operating Partnerships subsidiaries has been repaid in full.

The Senior Notes (excluding the Senior Notes due 2011) and the First Mortgage Notes are
redeemable prior to maturity subject to a premium on redemption, which is based upon interest rates of United States Treasury securities having similar average maturities as these notes. The premium that would have been due upon early retirement
approximated $114 million at December 31, 2006, and $148 million at December 31, 2005. The Senior Notes are unsecured. The First Mortgage Notes are collateralized by substantially all of the property, plant and equipment of the lumber,
plywood and MDF manufacturing facilities. The Senior Notes due 2011 are not redeemable prior to maturity.

The aggregate maturities on all debt agreements
and the line of credit are as follows as ofDecember 31, 2006(in millions):

The Operating Partnerships borrowing agreements contain various restrictive covenants, including limitations
on harvest levels, sales of assets, the incurrence of indebtedness and making restricted payments (such as payments of cash dividends or stock repurchases). The borrowing agreements limit our ability to make restricted payments (see Note 6 of the
Notes to Financial Statements) based on available cash, which is generally our net income (excluding gains on the sale of capital assets) after adjusting for non-cash charges (such as depreciation and depletion), changes in various reserves, less
capital expenditures and principal payments on indebtedness that are not financed. Additionally, the amount of available cash may be increased by the amount of proceeds from the sale of higher and better use properties and, under certain
circumstances, by 50% of the amount of net proceeds from the sale of other assets. Furthermore, our line of credit requires that we maintain certain interest coverage and maximum leverage ratios. The Operating Partnership was in compliance with all
of our borrowing agreement covenants as of December 31, 2006.

NOTE 5. FINANCIAL INSTRUMENTS

The carrying amounts of cash and cash equivalents and notes receivable approximate fair value due to the short-term maturities of these instruments.
The estimated fair value of the Operating Partnerships debt was approximately $2.38 billion and $2.32 billion at December 31, 2006 and 2005, respectively, and the carrying amount was $2.32 billion and $2.23 billion at
December 31, 2006 and 2005, respectively. The fair value of the Operating Partnerships publicly-traded debt (i.e. Senior Notes due 2015) is estimated using market quotes; the fair value of the remainder of the Operating Partnerships
debt is estimated using current interest rates for similar obligations with like maturities.

Certain investments in the grantor trusts relate to the
Operating Partnerships non-qualified pension plans and are classified as available-for-sale securities. The Operating Partnership has invested in various money market, debt and equity mutual funds and plans to use these investments to fund its
non-qualified pension obligations. The fair value of these investments was $19 million and $18 million at December 31, 2006 and 2005, respectively. Unrealized holding gains and losses are included as a component of accumulated other
comprehensive income, unless a permanent impairment has occurred, which is then charged to expense. Unrealized holding gains relating to mutual fund investments were approximately $4 million and $2 million at December 31, 2006 and 2005,
respectively. The Operating Partnership records changes in unrealized holding gains in Other Comprehensive Income. Realized gains and losses were less than $1 million in 2006, 2005, and 2004. See Note 7 of the Notes to Financial Statements
for discussion of the Operating Partnerships Pension Plans.

Certain investments in the grantor trusts relate to the Operating Partnerships
deferred compensation plans and are classified as trading securities. Deferred compensation amounts are invested in various money market, debt and equity mutual funds. The Operating Partnership plans to use these investments to fund deferred
compensation obligations. The fair value of these investments was $9 million at both December 31, 2006 and 2005. Unrealized holding gains related to mutual fund investments were $1 million at both December 31, 2006 and 2005. The
change in unrealized holding gains has been recognized in the Operating Partnerships Consolidated Statements of Income resulting in a gain of less than $1 million in 2006, a loss of less than $1 million in 2005, and a gain of $1 million in
2004. Realized gains and losses were less than $1 million in 2006, 2005, and 2004. Deferred compensation obligations are included in Other Liabilities and were $9 million at both December 31, 2006 and 2005.

NOTE 7. EMPLOYEE PENSION AND
RETIREMENT PLANS

Pension Plan.Plum Creek Timber Company, Inc. sponsors defined benefit pension plans that cover substantially all employees of the Operating Partnership. Therefore, all employee pension and retirement plan assets, obligations and costs are
allocated to the Operating Partnership. The Operating Partnership uses a December 31 measurement date for its pension plans. The following table provides a reconciliation of benefit obligations, plan assets, and funded status of the plans for
the years ended December 31(in millions):

The underfunded status of our plans of $34 million at December 31, 2006, is recognized in our Consolidated
Balance Sheet as a current pension liability of $3 million and long-term pension liability of $31 million. The accumulated benefit obligation was $100 million and $96 million at December 31, 2006 and December 31, 2005, respectively.

We adopted the recognition and disclosure provisions of SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other
Postretirement Plans (SFAS No. 158) on December 31, 2006. Under SFAS No. 158, we are required to recognize the funded status for our defined benefit plans in our December 31, 2006, Consolidated Balance Sheet. The
funded status is the difference between the fair value of plan assets and the projected benefit obligation. Recognizing the funded status resulted in a corresponding adjustment to accumulated other comprehensive income, net of tax. The adjustment to
accumulated other comprehensive income represents the net unrecognized actuarial losses and unrecognized prior service costs. Previously under the provisions of SFAS No. 87, Employers Accounting for Pensions(SFAS
No. 87), these amounts were netted against the plans funded status in our Consolidated Balance Sheets. These amounts will be subsequently recognized as pension cost pursuant to our historical accounting policy for amortizing such
amounts. The actuarial gains and losses that arise in subsequent periods and that are not recognized as pension cost in the same periods will be recognized as a component of other comprehensive income, and will be subsequently recognized as a
component of pension cost consistent with our historical policy for amortizing such amounts.

As of December 31, 2006, amounts that have not yet been recognized in pension cost and are included in
accumulated other comprehensive income (loss) are as follows:

During 2007, we expect $1 million of net actuarial loss and prior service cost to be recognized as a component of
pension cost.

Under SFAS No. 158, we recognized a liability in our Consolidated Balance Sheet at December 31, 2006, for our defined benefit
pension plans that are underfunded. Under the provisions of SFAS No. 87, the unfunded accrued pension cost at December 31, 2005 is set forth in the following table (in millions):

The unfunded accrued pension cost at December 31, 2005, consisted of accrued pension liability of
$17 million for the non-qualified pension plans and $3 million of prepaid pension cost for the qualified pension plan.

To develop the expected long-term rate of return on plan assets assumption, the Operating Partnership considered
the current level of expected returns on risk free investments (primarily government bonds), the historical level of the risk premium associated with the other asset classes in which the portfolio is invested and the expectations for future returns
on each asset class. The expected return for each asset class was then weighted based on the target asset allocation to develop the expected long-term rate of return on plan assets assumption for the portfolio. This resulted in the selection of the
7.75% assumption as of January 1, 2006 and 2005.

Most of the Operating Partnerships salaried and all hourly employees who complete one year of
service in which they work at least 1,000 hours are eligible to participate in the plan. Participants vest after five years of service. The cash balance benefits for salaried employees is determined based primarily on certain percentages of
compensation, age, years of service and interest accrued based on the 30-year Treasury bond rate. Participants who were employees of the Operating Partnership on September 1, 2000, earn benefits based on the greater of the cash balance formula
or a monthly pension benefit that is principally based on the highest monthly average earnings during any consecutive sixty-month out of 120-month period and the number of years of service credit. The benefits to hourly employees are generally based
on a fixed amount per year of service.

The Operating Partnership maintains a qualified defined benefit pension plan and two supplemental (non-qualified)
defined benefit pension plans. The Operating Partnerships contributions to these plans vary from year to year. It is the Operating Partnerships policy to fund the qualified plan annually by either the value of the benefits earned during
the year or, if more, the amount such that the fair value of plan assets equals or exceeds the actuarially computed accumulated benefit obligation (the approximate actuarially computed current pension obligation if the plan was discontinued).

The Operating Partnership has the same funding policy for the non-qualified plans. However, assets related to the non-qualified plans are held in a grantor
trust and are subject to the claims of creditors in the event of bankruptcy. As a result, pension assets for the non-qualified plans are not considered plan assets, and therefore, have not been netted against our pension liability. Pension assets
for the non-qualified plans are included in Investment in Grantor Trusts and the related pension liability is included in Other Liabilities and Other Current Liabilities in our Consolidated Balance Sheet. At
December 31, 2006 and 2005, the accumulated benefit obligation for the non-qualified plans was $19 million and $17 million, respectively. The fair value of assets held in a grantor trust associated with the non-qualified plans was
$19 million at December 31, 2006, and $18 million at December 31, 2005.

As a result of the Operating Partnerships funding policy,
annual qualified pension contributions and grantor trust funding are significantly impacted by investment returns and changes in interest rates. Based on current interest rates and expected investment returns, the Operating Partnership expects 2007
contributions to the qualified pension plan to range between $2 million and $5 million. Additionally, during 2007 the Operating Partnership expects to contribute between $1 million and $3 million to its grantor trust associated with
the non-qualified plans.

It is the Operating Partnerships investment policy to achieve maximum returns at a reasonable risk for
pension assets over a full market cycle. The Operating Partnership uses eight fund managers to capture favorable returns in various asset classes and to diversify risk. At December 31, 2006, target allocations for the various asset classes are
as follows:



|                                                    |  |           
|--------------------------------------------------- |  | ----------
|                                                   
|Large Capitalization Domestic Equities              |  | 25% TO 37%
|Small and Mid-Size Capitalization Domestic Equities |  | 8% TO 14% 
|International Equities                              |  | 12% TO 16%
|Fixed Income                                        |  | 31% TO 37%
|Hedge Funds                                         |  | 8% TO 12% 
|                                                   
|                                                   
|                                                   

Pension assets are analyzed at least quarterly and rebalanced as needed to maintain the above target allocations.
To further reduce risk, fund managers are required to invest in a diversified portfolio. No more than 5% of an equity portfolio can be invested in a single company and fund managers are expected to be well diversified with respect to industry and
economic sectors. No more than 10% of a fixed income portfolio can be invested in a single issuer (other than U.S. treasuries). Equity investments are limited to common stocks, common stock equivalents and preferred stock. Fixed income investments
are limited to U.S. treasuries, agencies of the U.S. Government, domestic corporations, municipalities, domestic banks, and other U.S. financial institutions. Furthermore, hedge funds are used to reduce market risk and generate absolute returns
regardless of market direction by employing limited use of derivative instruments, selling securities short, and buying and selling futures and options contracts.

Over a full market cycle, the investment goal for large capitalization domestic equities and fixed income investments is to exceed the applicable benchmark (e.g., S&P 500 Index) by one-half of one percent per annum, and the investment
goal for small and mid-size capitalization domestic equities and international equities is to exceed the applicable benchmark (e.g., Russell 2000 Value Index) by one percent. The investment goals are net of related fees.

NOTE 8. SHAREBASED COMPENSATION PLANS

Plum Creek Timber Company, Inc. has a stockholder approved Stock Incentive Plan that provides for the award of non-qualified stock options, restricted stock and
restricted stock units, value management awards and dividend equivalents. Certain executives and key employees of the Operating Partnership are covered by this plan. All of Plum Creeks activities are conducted through the Operating
Partnership, therefore all share-based compensation expense is allocated to the Operating Partnership. Proceeds from the exercise of Plum Creek stock options are retained by Plum Creek Timber Company, Inc.

Under Plum Creeks Stock Incentive Plan (the Plan), as amended in May 2004, there are 12.4 million shares of common stock reserved and eligible for
issuance. At December 31, 2006, 3.3 million shares of the 12.4 million reserved shares have been used and, therefore, 9.1 million shares remain available for grants of non-qualified stock options, grants of restricted stock and
restricted stock units, or payments of vested value management awards and dividend equivalents. The number of shares to be issued in connection with value management awards and dividend equivalents is not determined until the end of their respective
performance periods. New shares of Plum Creek Timber Company, Inc. are issued for payment under the Plan for awards that pay out in shares or where the participant can elect payment in shares.

Stock Options.Under the Plan, non-qualified stock options
may be granted to any officer, director, employee, consultant or advisor of the Operating Partnership. Each stock option granted allows the recipient the right to purchase Plum Creeks common stock at the fair market value of Plum Creeks
common stock on the date of the grant. Generally, the stock options have a ten-year term and vest over a four-year period at a rate of 25% per year. Under the Plan, the exercise price of an option may not be reduced.

Presented below is a summary of Plum Creeks stock option Plan activity for theyear ended December 31,
2006:

Value Management Awards.Value management awards provide incentive compensation to participants that is contingent upon Plum Creeks performance over a three-year period measured against the performance of peer groups consisting of forest
products companies, the S&P 500 Index and the Morgan Stanley REIT Index over the same period (Peer Group).

Value management awards are earned in whole or in part based on a sliding scale. No value management award is earned if Plum Creeks total shareholder return is below the 50thpercentile of the Peer Group. The full value management award is earned if Plum Creeks total shareholder return is above the 75thpercentile. A unit has a face value of $100. The value of an award between the 50thand 75thpercentiles is
based on a sliding scale between 0% and 200% of the face value. Amounts earned, if any, are paid in the quarter immediately following the end of the three-year performance period. Unless otherwise specified by the participant, each payment will be
paid in cash, except that any officer not in compliance with Plum Creeks stock ownership guidelines is required to receive up to half of the payment value in Plum Creeks common stock. Generally, to be entitled to the payment, a
participant must be employed by the Operating Partnership on the last day of the performance period.

Value management awards activity was as follows for
theyear ended December 31, 2006:

|A | The estimated fair value includes unrecognized compensation expense.
|- | --------------------------------------------------------------------



|B | Maximum award value is based on a unit value of $200.
|- | -----------------------------------------------------

The three-year
performance period for the 2004 grants ended on December 31, 2006; amounts earned of $2.5 million, based on a unit value of $74, were paid (primarily in cash) during the first quarter of 2007. There were no value management award payments
during the first quarter of 2006 because no awards had a performance period ending December 31, 2005. The three-year performance period for the 2002 grants ended on December 31, 2004; amounts earned of $9 million were paid (primarily in
cash) during the first quarter of 2005. The three-year performance period for the 2000 grants ended on December 31, 2002; amounts earned of $8.9 million, based on a unit value of $200, were paid half during the first quarter of 2003 and half
during the first quarter 2004.

Dividend Equivalents.Under the Plan, dividend equivalents may be granted in connection with stock options. Dividend equivalents represent the right to receive a payment equal in value to the per-share dividend paid over a five-year period by Plum Creek
multiplied by the number of unexercised stock options. No dividend equivalents were awarded during 2006.

For awards granted in 2005 and 2004, each year during the five-year performance period, a participant may be eligible to earn a percentage of Plum Creeks current year dividend plus a percentage of prior year unearned dividends to the
extent that Plum Creek has achieved a minimum level of total shareholder return. The total shareholder return computation consists of Plum Creeks stock price appreciation plus dividends paid. The specific percentage to be applied to any such
earned dividends for a given year of the performance period is contingent upon Plum Creeks performance for that year measured against the performance of the Peer Group. Dividends are earned in whole or in part based on a sliding scale. If Plum
Creeks total shareholder return is below the 50thpercentile of the Peer Group, the percentage amount is zero.
If Plum Creeks total shareholder return is at or above the 75thpercentile, the full amount of the dividend is
earned. If Plum Creeks relative performance is between the 50thand the 75thpercentiles, dividend equivalents are valued based on a sliding scale between 50% and 100% of the dividends paid during the year. The minimum level
of total shareholder return must be at least 5.5% on an annualized basis.

For awards granted prior to 2004, each year during the respective five-year
performance period, a participant may earn an amount equal to Plum Creeks current year dividend plus prior year unearned dividends to the extent Plum Creeks total shareholder return on an annualized basis equals or exceeds 13% for 15
trading days out of any 30 trading day period in any given year.

Payments related to any earned dividend equivalents are made at the end of the five-year
performance period. Amounts earned, if any, are paid in the quarter immediately following the end of the five-year performance period. Unless otherwise specified by the participant, each payment is paid in cash, except that any officer not in
compliance with Plum Creeks stock ownership guidelines is required to receive up to half of the payment value in Plum Creeks common stock. If a participant terminates employment prior to the end of the five-year performance period, a
cash payment is made for any performance goals achieved in connection with vested stock options through the last day of employment. Payment related to unvested stock options and performance goals achieved after termination of employment are
forfeited. At December 31, 2006, 1.5 million dividend equivalents, net of forfeitures, granted to employees, officers and directors of the Operating Partnership were outstanding.

|A | The estimated fair value includes unrecognized compensation expense.
|- | --------------------------------------------------------------------



|B | Maximum award value is calculated based on earned dividends to date plus potential future unearned dividends assuming a quarterly dividend rate of $0.42 per share.
|- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------

The five-year performance period for the 2002 grants ended on December 31, 2006; amounts earned of $1.7 million were paid (primarily in
cash) during the first quarter of 2007. The five-year performance period for the 2001 grants ended on December 31, 2005; amounts earned of $3 million were paid (primarily in cash) during the first quarter of 2006. The five-year performance
period for the 2000 grants ended on December 31, 2004; amounts earned of $3 million were paid (primarily in cash) during the first quarter of 2005. No dividends equivalents were awarded prior to 2000.

Measurement of Compensation Costs for Value Management Awards and Dividend Equivalents.Grants of both value management awards and dividend equivalents represent awards that are classified and accounted for as liabilities under SFAS No. 123(R). As a result, the expense recognized
over the performance period for both value management awards and dividend equivalents will equal the fair value (i.e., cash value) of an award as of the last day of the performance period multiplied by the number of awards that are earned.
Furthermore, SFAS No. 123(R) requires the quarterly expense recognized during the performance period to be based on the fair value of value management awards and dividend equivalents as of the end of the most recent quarter. Prior to the end of
the performance period, compensation costs for value management awards and dividend equivalents are based on the awards most recent quarterly fair values and the number of months of service rendered during the performance period.

Fair values for value management awards and dividend equivalents are computed based on Plum Creeks historical relative total shareholder return compared to the
Peer Group from the beginning of the performance period to the end of the most recent quarter, and Plum Creeks simulated relative total shareholder return through the end of the performance period. The simulated total shareholder return of
Plum Creek and the Peer Group is computed using a Monte Carlo simulation. The key assumptions used in the simulation of Plum Creeks and the Peer Groups total shareholder return are volatility, beta (the measure of how Plum Creeks
stock moves relative to the market as a whole), risk-free interest rate, and expected dividend yield. Additionally, the fair value of dividend equivalents assumes that the current quarterly dividend of Plum Creek common stock of $0.42 per share will
remain constant through the end of the performance period.

Accounting for Share-Based
Compensation.The Operating Partnership expenses share-based employee compensation in accordance with the fair value recognition provisions of SFAS No. 123(R), Share-Based
Payment. Under the modified-prospective method adopted by the Operating Partnership on January 1, 2006, share-based employee compensation cost is recognized using the fair value method for all employee awards granted, modified, or settled
on or after January 1, 2006 (see Accounting for Share-Based Compensation in Note 1 of the Notes to Financial Statements). Stock options and most restricted stock units vest 25% per year over a four-year vesting period.
Compensation cost related to these graded vesting awards is recognized using the straight-line method over the four-year vesting period. Total compensation expense for the above share-based compensation plans (including both awards paid in stock and
cash) was approximately $9 million, $9 million and $13 million for the years ended December 31, 2006, 2005, and 2004, respectively. For the years ended

December 31, 2006, 2005, and 2004, the Operating Partnership recognized $2 million, $2 million, and $3 million, respectively, in tax benefits associated
with share-based compensation plans. At December 31, 2006, there was $12 million of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the Plan. That cost is expected to be recognized
over a weighted-average period of approximately 3 years.

NOTE 9. RELATED-PARTY TRANSACTIONS

Transactions with Parent.The Operating
Partnerships parent, Plum Creek Timber Company, Inc., provides pension plans and share-based and deferred compensation plans that cover employees of the Operating Partnership (see Notes 7 and 8 of the Notes to Financial Statements). All
of Plum Creeks activities are conducted through the Operating Partnership. Therefore, all pension and share-based compensation expense is allocated to the Operating Partnership.

PLUM CREEK TIMBERLANDS, L.P.

NOTES TO
CONSOLIDATED FINANCIAL STATEMENTS (continued)



NOTE 11. COMMITMENTS AND
CONTINGENCIES

Contingencies.The
Operating Partnership is subject to regulations regarding forest and harvest practices and is, from time to time, involved in various legal proceedings, including environmental and regulatory matters, incidental to its business. Moreover, the
Operating Partnership is currently in the early stages of several lawsuits related to property damage caused by various sources (Property Damage Litigations). The Operating Partnership believes it is more likely than not that the
Property Damage Litigations will be resolved favorably. However, the final outcome of any legal proceeding is subject to many variables and cannot be predicted with any degree of certainty. The Operating Partnership believes that there are
meritorious defenses for these claims and is vigorously defending these matters.

Environmental
Contingencies.In connection with the October 6, 2001 merger with The Timber Company, Plum Creek agreed to indemnify Georgia-Pacific for substantially all of the liabilities
attributed to The Timber Company. During 2003, Georgia-Pacific provided the Operating Partnership with information about the existence of mine tailings and approximately 4.5 billion gallons of acidic surface water on approximately 90 acres in
Hot Spring County, Arkansas, on former Georgia-Pacific properties (Arkansas Environmental Issue). Barite mining and related activities were conducted on the site between 1939 and 1981 in part by lessees of an entity that was acquired by
Georgia-Pacific. The site is currently being investigated and no remediation plan has yet been approved. No amounts have been accrued for this potential liability. Furthermore, to the extent the Operating Partnership is required to indemnify
Georgia-Pacific for its share of the remediation costs, the Operating Partnership may be able to recover a portion of its cost from Georgia-Pacifics insurance policy, or indemnity obligations of the various lessees that conducted mining
operations on the property, or both.

Unrecorded Contingencies.The Operating Partnership believes it will be successful in defending the Property Damage Litigations and the Arkansas Environmental Issue. However, if the Operating Partnership is not successful in defending these claims,
we believe the aggregate combined losses for the Property Damage Litigations and Arkansas Environmental Issue would range between $0 and $4 million. Other than the Property Damage Litigations and the Arkansas Environmental Issue, management
currently believes that resolving pending legal proceedings against the Operating Partnership, individually or in aggregate, will not have a material adverse impact on our financial position or results of operations. However, these matters are
subject to inherent uncertainties and managements view on these matters may change in the future. Were an unfavorable final outcome in one or multiple legal proceedings to occur, there exists the possibility of a material adverse impact on our
financial position and the results of operations for the period in which any unfavorable outcome becomes reasonably estimable.

Contractual Obligations.The Operating Partnership has contracted to source logs and supply fiber with customers under long-term agreements at prevailing
market rates. The agreements expire beginning in 2007 through 2023, with various renewal options by either party for periods ranging from three years to 15 additional years.

Lease Commitments.The Operating Partnership leases buildings and equipment under noncancelable
operating lease agreements. Operating lease expense was $7 million in 2006, $5 million in 2005 and $3 million in 2004. The Operating Partnership leases certain timberlands in which the Operating Partnership acquired title to the standing timber
at the inception of the lease. The following summarizes the future minimum operating lease payments and obligations in connection with leasing timberlands atDecember 31, 2006(in millions):

NOTE 12. SEGMENT INFORMATION

The Operating Partnership is organized into nine business units on the basis of both product line and geographic region. Each business unit has a
separate management team due to geographic location, marketing strategies and/or production processes. In applying SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information, these business units have been
aggregated into five reportable segments based on similar long-term economic characteristics. The Operating Partnerships reportable segments are: (1) Northern Resources, (2) Southern Resources, (3) Real Estate,
(4) Manufactured Products and (5) Other.

Northern Resources Segment.The Northwest Resource region and the Northeast Resource region are aggregated into the Northern Resources Segment. The Northern Resources Segment consists of timberlands located in Maine, Michigan,
Montana, New Hampshire, Oregon, Washington, West Virginia and Wisconsin. The Northern Resources Segment grows timber for sale primarily in domestic regional markets. Additionally, some logs are sold in export markets, mainly Canada. The Northern
Resources Segment sells softwood and hardwood sawlogs and softwood and hardwood pulpwood. Softwood sawlogs are sold to regional lumber and plywood manufacturers. Logs harvested in Montana are sold mostly to our lumber and plywood mills (which are
part of the Manufactured Products Segment). Hardwood sawlogs are sold primarily to furniture manufacturers. Softwood and hardwood pulpwood is sold to regional paper and packaging manufacturers.

Southern Resources Segment.The Gulf South Resource
region and the Atlantic South Resource region are aggregated into the Southern Resources Segment. The Southern Resources Segment consists of timberlands located in Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina,
Oklahoma, South Carolina and Texas. The Southern Resources Segment grows timber for sale in domestic regional markets. The Southern Resources Segment sells primarily softwood sawlogs and pulpwood. Softwood sawlogs are sold to regional lumber and
plywood manufacturers. Softwood pulpwood is sold to regional paper and packaging manufacturers. Additionally, the Southern Resources Segment leases our timberlands to third parties on an annual basis for recreational purposes.

Real Estate Segment.The Real Estate Segment
consists of sales of higher and better use timberlands and sales of non-strategic timberlands. We estimate that included in our approximately 8.2 million acres of timberlands are about 1.7 million acres of higher and better use
timberlands, which are expected to be sold and/or developed over the next 15 years for residential, recreational or conservation purposes. In addition, the Operating Partnership has approximately 400,000 acres of non-strategic timberlands, which are
expected to be sold over the next five years. In the meantime, these timberlands continue to be used productively in our business of growing and selling timber. Included within the 1.7 million acres of higher and better use timberlands are
approximately 225,000 acres that will be developed by the Operating Partnerships wholly-owned taxable REIT subsidiaries. Properties developed internally by the Operating Partnership will generally be low-intensity development limited to
obtaining entitlements and investing in infrastructures such as roads and utilities. Larger and more complicated projects, such as destination resorts and master planned communities, will be developed through joint venture arrangements in which we
are the minority partner and our involvement is limited to selling and/or contributing timberlands and exercising certain protective rights.

Manufactured Products Segment.The lumber, plywood and medium density fiberboard (MDF) businesses are aggregated into the Manufactured Products Segment. The
Manufactured Products Segment consists of four lumber mills, two plywood mills, two MDF facilities, one lumber remanufacturing facility in Montana, and one lumber remanufacturing facility in Idaho. The lumber facilities produce boards, studs, and
dimension lumber and the panel facilities produce high-quality plywood and MDF panels. All of these products are targeted to domestic lumber retailers, home construction, industrial customers, and to a lesser extent, for export primarily to Canada.
Residual chips that are not used internally are sold to regional pulp and paper manufacturers. Revenues from manufactured products by product line were as follows for the years ended December 31 (in millions):



|        |  |        |  |        |  |       
|------- |  | ------ |  | ------ |  | ------

|        |  |        |  |        |  |       
|       
|       

Other Segment.The Other Segment consists primarily of income associated with mineral extraction, natural gas production and communication and transportation rights of way. Mineral income consists of royalty revenue from the extraction of oil and
gas, natural aggregates and coal (until the first quarter of 2005).

In the fourth quarter of 2004, the Operating Partnership sold certain subsurface
property rights (primarily coal reserves, excluding coalbed methane, oil and gas reserves) in Buchanan County, Virginia, to Consol Energy, Inc. The Operating Partnership received proceeds of $23 million in connection with the sale and the
release of certain legal claims, which the Operating Partnership believes comprised a portion of the proceeds. However, the sale agreement did not specify an allocation. The net gain from this sale and settlement of certain legal claims, after
reducing the proceeds for applicable income taxes, was $23 million. During the first quarter of 2005, we sold our remaining coal reserves for proceeds of $21 million. The net gain from this sale after reducing the proceeds for our book basis
and applicable income tax, was $20 million. Prior to these sales, substantially all of the coal reserves were subject to long-term mineral leases. For the year ended December 31, 2004, the Other Segment revenues and operating income included
approximately $1 million from royalties associated with the mineral leases, and less than $1 million in 2005. These gains have been reported in our Consolidated Statements of Income as a separate line item below Income from Continuing Operations.

The Operating Partnership evaluates performance and allocates capital to the segments based on operating income before interest, unallocated corporate
expenses and taxes. Asset information is not reported by segment, as the Operating Partnership does not produce such information internally.

|B | The Operating Partnership recognized impairment losses on sales of timberlands expected to close within a twelve-month period of $2 million in 2006, $1 million
during 2005, and $21 million during 2004. Impairments are recognized as part of cost of goods sold and reflected as part of operating income.

jointly explored for and developed coalbed methane gas found on certain of its timberlands in West Virginia and Virginia. During the second quarter of 2004, the Operating Partnership sold its working interest in the joint operating agreement to
Geomet, Inc. for $27 million. The resulting gain of $5 million before income taxes is included in Other Operating Income (Expense), net in our operating income for 2004. The agreement provides for contingent additional sales proceeds of up to
$3 million payable at the end of 2007. The impact on operating income from our working interest in the joint operating agreement during the year ended December 31, 2004 was less than $1 million.

PLUM CREEK TIMBERLANDS, L.P.

REPORT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Partners of

Plum Creek Timberlands, L.P.

We have audited the accompanying consolidated balance sheets of Plum Creek Timberlands, L.P.
as of December 31, 2006 and 2005, and the related consolidated statements of income, partners capital, and cash flows for each of the three years in the period ended December 31, 2006. These financial statements are the
responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We
conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Companys internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.
An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Plum Creek
Timberlands, L.P. at December 31, 2006 and 2005, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2006, in conformity with U.S. generally accepted
accounting principles.

As discussed in Note 1 to the consolidated financial statements, in 2006 the Company changed its method of accounting for
share-based payments and also changed its method of accounting for its defined benefit pension plan.

PLUM CREEK TIMBER COMPANY, INC.

REPORT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Plum Creek Timber Company, Inc.

We have audited managements assessment, included in the accompanying Management
Report, that Plum Creek Timber Company, Inc. maintained effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (the COSO criteria). Plum Creek Timber Company, Inc.s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness
of internal control over financial reporting. Our responsibility is to express an opinion on managements assessment and an opinion on the effectiveness of the companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial
reporting, evaluating managements assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit
provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with
authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material
effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, managements assessment that Plum Creek Timber Company, Inc. maintained effective internal control over financial reporting as of
December 31, 2006, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, Plum Creek Timber Company, Inc. maintained, in all material respects, effective internal control over financial reporting as of
December 31, 2006, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the consolidated balance sheets of Plum Creek Timber Company, Inc. as of December 31, 2006 and 2005, and the related consolidated statements of income, stockholders equity and cash flows for each of the three years in the
period ended December 31, 2006 of Plum Creek Timber Company, Inc. and our report dated February 16, 2007 expressed an unqualified opinion thereon.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Controls and Procedures

(a)    DISCLOSURE CONTROLS AND PROCEDURES

The companys management, with the participation of the
companys Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the companys disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act
of 1934, as amended) as of the end of the period covered by this report. Based on that evaluation, the companys management, including the Chief Executive Officer and Chief Financial Officer, has concluded that the companys disclosure
controls and procedures were effective as of the end of such period.

(b)    CONTROL OVER FINANCIAL REPORTING

There have been no changes in the companys internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities
Exchange Act of 1934, as amended) during the quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, the companys internal control over financial reporting.

Managements Report on Internal Control over Financial Reporting

The management
of Plum Creek Timber Company, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended). Our system of
internal control over financial reporting is designed to provide reasonable assurance to the companys management and Board of Directors regarding the preparation and fair presentation of the consolidated financial statements for external
purposes in accordance with generally accepted accounting principles.

Plum Creek Timber Company, Inc.s management, under the supervision of the Chief
Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of December 31, 2006. In making this assessment, we used the framework included in Internal ControlIntegrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the criteria set forth in Internal ControlIntegrated Framework, management concluded that our internal control
over financial reporting was effective as of December 31, 2006.

Because of its inherent limitations, internal control over financial reporting may not
prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or
procedures may deteriorate.

Managements assessment of the effectiveness of our internal control over financial reporting as of December 31,
2006, has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report, which is included herein.
