OUR BUSINESS
We are one of the world's largest private owners of timberlands. We own or control nearly 712.2 million acres of timberlands primarily in the U.S., and manage an additional 14.0 million acres of timberlands under long-term licenses in Canada. We manage these timberlands on a sustainable basis in compliance with internationally recognized forestry standards. Our objective is to maximize the long-term value of timberlands we own. We analyze each timberland acre comprehensively to understand its highest-value use. We realize this value in many ways, particularly through growing and harvesting the trees, but also by selling properties when we can create incremental value. In addition, we focus on opportunities to realize value for oil and natural gas production, construction aggregates and mineral extraction, wind and solar power, communication tower leases and transportation rights of way that exist in our ownership.
We are also one of the largest manufacturers of wood products in North America. We manufacture and distribute high-quality wood products, including structural lumber, oriented strand board (OSB), engineered wood products and other specialty cellulose fibers products. These products are primarily supplied to the residential, multi-family, industrial, light commercial and repair and remodel markets. We operate 35 manufacturing facilities in the United States and Canada.

Today, we are working to grow a truly greatbe the world's premier timber, land, and forest products company for our shareholders, customers and employees. We grow and harvest trees and manufacture and sell products made from trees.

REAL ESTATE INVESTMENT TRUST (REIT) ELECTION
Starting with our 2010 fiscal year, we elected to be taxed as a REIT. We expect to derive most of our REIT income from investments in timberlands, including the sale of standing timber through pay-as-cut sales contracts and lump sum timber deeds. REIT income can be distributed to shareholders without first paying corporate level tax, substantially eliminating the double taxation on income. A significant portionWe expect to derive most of our timberland segment earnings receives this favorable tax treatment.REIT income from our timberlands, including gains from the sales of our standing timber and rent from recreational leases. We continue to be required to pay federal corporate income taxes on earnings of our Taxable REIT Subsidiary (TRS), which includes our manufacturing businessesWood Products segment and thea portion of our Timberlands segment income included in the TRS.
PENDING MERGER WITH PLUM CREEK
On November 6, 2015 Weyerhaeuser Company and Plum Creek Timber Company, Inc. (“Plum Creek”) entered into an AgreementReal Estate, Energy and Plan of Merger (“Merger Agreement”) pursuant to which Plum Creek will merge with and into Weyerhaeuser Company with Weyerhaeuser continuing as the surviving corporation. Under the terms of the Merger Agreement, Plum Creek shareholders will receive 1.60 shares of Weyerhaeuser common shares for each share of Plum Creek common stock at the closing date.

On November 8, 2015 Weyerhaeuser announced that the board authorized the exploration of strategic alternatives for its Cellulose Fibers business. At this time there can be no assurance that the board's evaluation process will result in any transaction or that any transaction, if pursued, will be consummated.

EFFECT OF MARKET CONDITIONS
The health of the U.S. housing market strongly affects the performance of all our Wood Products and Timberlandsbusiness segments. Wood Products primarily sells into the new residential building and repair and remodel markets. Demand for logs from our Timberlands segment is affected by the production of wood-based building products as well as export demand. Cellulose FibersReal Estate is primarily affected by globallocal real estate market conditions, such as the level of supply or demand for properties sharing the same or similar characteristics as our timberlands. Energy and the relative strength of the U.S. dollar.Natural Resources is affected by underlying demand for commodities, including oil and gas.

COMPETITION IN OUR MARKETS
We operate in highly competitive domestic and foreign markets, with numerous companies selling similar products. Many of our products also face competition from substitutes for wood and wood-fiber products.

manufacturing facilities at cost and do not generate any significant profit in the Timberlands segment from the harvest of timber from the licensed acres in Canada.
Other Values From Our Timberlands
In the United States, we actively manage mineral, oil and gas leases on our land and use geologic databases to identify and market opportunities for commercial mineral and geothermal development. We recognize leasing, bonus, and option revenue over the terms of agreements with customers. Revenue primarily comes from:
royalty payments on oil and gas production;
bonus payments from oil and gas leasing and exploration activity;
royalty payments on hard minerals (rock, sand and gravel);
geothermal lease and option revenues; and
the sale of mineral assets.
In managing mineral resources, we generate revenue related to our ownership of the minerals and, separately, related to our ownership of the surface. The ownership of mineral rights and surface acres may be held by two separate parties. Materials that can be mined from the surface, and whose value comes from factors other than their chemical composition, typically belong to the surface owner. Examples of surface materials include rock, sand, gravel, dirt and topsoil. The mineral owner holds the title to commodities that derive value from their unique chemical composition. Examples of mineral rights include oil, gas, coal (even if mined at the surface) and precious metals. If the two types of rights conflict, then mineral rights generally are superior to surface rights. A third type of land right is geothermal, which can belong to either the surface or mineral owner. We routinely reserve mineral and geothermal rights when selling surface timberlands acreage.

HOW WE MEASURE OUR PRODUCT
We report Timberlands data in cubic meters. Cubic meters measure the total volume of wood fiber in a tree or log that we can sell. Cubic meter volume is determined from the large and small-end diameters and length and provides a comparative measure of timber and log volume among operating regions, species, size and seasons of the year.
We also use multiple units of measure when transacting business including:
Thousand board feet (MBF) — used in the West to measure the expected lumber recovery from a tree or log. This measure does not include taper or recovery of non-lumber residual products.
Hundred cubic feet (CCF) — used in the West to measure the volume of a log. The measure does not include any calculation for expected lumber recovery.log; and
Green tons (GT) — used in the South to measure weight; factors used for conversion to product volume can vary by species, size, location and season.
We report Timberlands volumes in ton equivalents.
WHERE WE DO IT
Our timberlands assets are located primarily in North America. In the U.S. we own andWe sustainably manage sustainable timberlands in nine states for usetwenty states. This includes owned or contracted acres in wood productsthe following locations:
2.9 million acres in the western U.S. (Oregon and pulp and paper manufacturing. We own or lease:Washington);

2.62.4 million acres in the Pacific Northwest (Oregonnorthern U.S. (Maine, Michigan, Montana, New Hampshire, Vermont, West Virginia and Washington)Wisconsin).

We also own and operate nurseries and seed orchards in Washington, Oregon, South Carolina and Georgia.
Our international operations are located in Uruguay, where we own 298,000 acres and have long-term leases on 25,000 acres. In Canada, we manage timberlands under long-term licenses that provide raw material for our manufacturing facilities. These licenses are in Alberta, British Columbia, Ontario (license is managed by partnership) and Saskatchewan.Saskatchewan (license is managed by partnership).
Our total timber inventory — including timber on owned and leasedcontracted land— is approximately 350626 million cubic meters.tons. The amount of timber inventory does not translate into an amount of lumber or panel products because the quantity of end products:
products varies according to the species, size and quality of the timber; and
will change through time as the mix of these variables adjust.

WEYERHAEUSER COMPANY > 2015 ANNUAL REPORT AND FORM 10-K3



The species, size and grade of the trees affects the relative value of our timberlands.
We maintain our timber inventory in an integrated resource inventory system and geographic information system (“GIS”). The resource inventory component of the system is proprietary and is largely based on internally developed technologies,methods, including growth and yield models developed by our research and development organization. The GIS component is based on GIS software that is viewed as the standard in our industry.
Timber inventory data collection and verification techniques include the use of industry standard field sampling procedures as well as proprietary remote sensing technologies in some geographies where they generate improved estimates.geographies. The data is collected and maintained at the timber stand level.

2015 Western U.S. Inventory by Species
2015 Western U.S. Inventory by Age / Species
The average age of timber harvested in 2015 was 52 years. Most of our U.S. timberland is intensively managed for timber production, but some areas are conserved for environmental, historical, recreational or cultural reasons. Some of our older trees are protected in acreage set aside for conservation, and some are not yet logged due to harvest rate regulations. While over the long term our average harvest age will decrease in accordance with our sustainable forestry practices, we harvest generally 2 percent of our Western acreage each year.
Southern United States
Our Southern acres predominantly contain southern yellow pine and encompass timberlands in seven states.
We intensively manage our timber plantations using forestry research and planning systems to optimize grade log production. We also actively manage our land to capture revenues from our oil, gas and hard minerals resources. We do this while providing quality habitat for a range of animals and birds. We lease more than 94 percent of our acres to the public and state wildlife agencies for recreational purposes.

Southern United States
Our Southern timberland acres in Uruguayownership, covering 11 states, is well situated to serve domestic wood products and pulp markets, including third-party customers and our own mills. For the year ended December 31, 2018, we sold 24 percent of our total southern log sales volume internally. Additionally, our Atlantic and Gulf coastal locations position us to serve a developing Asian log export market. Our holdings are split approximately 49comprised of 76 percent loblollySouthern yellow pine and 5124 percent eucalyptus. Loblolly pine compriseshardwoods.
We intensively manage our Southern timber plantations using:
forestry research and planning systems to optimize log production,
customized silviculture prescriptions which increase productivity across our acreage and
innovative planting and harvesting techniques on varying Southern terrain.
Operationally, we focus on efficiently harvesting and hauling logs from our ownership and capitalizing on our scale and supply chain expertise to consistently and reliably serve a broad range of customers through seasonal and weather-related events year-round.
We lease more than 94 percent of our timber inventory due to its older age. On average, the timber in Uruguay is in the second third of its rotation age. It is entering into that part of the growth rotation when we will see increased volume accretion. About 97 percent of the area to be planted has been afforested to date.owned Southern acreage for recreational purposes.

2018 Southern U.S. Inventory by Species (Uruguay)
tl3southernusinventorybysp.jpg
In Uruguay, the target rotation ages are 21 to 22 years for pine and 14 to 17 years for eucalyptus. We manage both species to a grade (appearance) regime.
We also operate a plywood mill in Uruguay with a production capacity of 250,000 cubic meters. Production volume reached 218,000 cubic meters in 2015.
In Brazil, we were a managing partner in a joint venture that operated a hardwood sawmill. We sold our interest in this joint venture during 2014.

2018 Southern U.S. Inventory by Age / Species
tl4susinvagebyspecie201810.jpg
The average age of timber harvested from our Southern timberlands in 2018 was 31 years. In accordance with our sustainable forestry practices, we harvest approximately 3 percent of our acreage each year in the South.
Northern United States
We are one of the largest private owners of northern hardwood timberlands. Our Northern acres contain a diverse mix of temperate broadleaf hardwoods and mixed conifer species across timberlands located in seven states. We grow over 50 species and market over 600 product grades to a diverse mix of customers.
Our large-diameter cherry, red oak and hard maple saw logs and veneer logs serve domestic and export furniture markets. Our maple and other appearance woods are used in furniture and high-value decorative applications. In addition to high value hardwood saw logs, our mix includes hardwood fiber logs for pulp and OSB applications. Hardwood pulpwood is a significant market in the Northern region and we have long term supply agreements, primarily at market rates, for nearly 83 percent of our hardwood pulp production.
We also grow softwood logs that supply our Montana medium density fiberboard (MDF), lumber and plywood mills and other customers. Our competitive advantages include a merchandising program to capture the value of the premium hardwood logs.
Regeneration is predominantly natural, augmented by planting where appropriate.

Canada — Licensed Timberlands
We manage timberlands in Canada under long-term licenses from the provincial governments to secure volume for our manufacturing facilities in various provinces. The provincial governments regulate the volume of timber that may be harvested each year through Annual Allowable Cuts (AAC), which are updated every 10 years. As of December 31, 20152018, our AAC by province was: 
Alberta — 3,9062,914 thousand cubic meters,tons,
British Columbia — 804547 thousand cubic meters,tons,
Ontario — 146154 thousand cubic meterstons and
Saskatchewan — 788634 thousand cubic meters.tons.
When the volume is harvested, we pay the province for that volume at stumpage rates set by the government and generally based on prevailing market prices.government. The harvested logs are transferred to our manufacturing facilities at cost (stumpage plus harvest, haul and overhead costs less any margin on selling logs to third parties). Any profit from harvesting the log through to converting it to a finished productproducts is recognized at the respective mill in either the Cellulose Fibers orour Wood Products segment.
A small amount of harvested volumes are sold to unaffiliated customers.

Our Timberlands annual fee harvest volumes represents the depletion of the timber assets we own. Depletion is a method of expensing the cost of establishing the fee timber asset base over the harvest or timber sales volume.HOW MUCH WE HARVEST
Our fee harvest volumes are managed sustainably across all regions to ensure the preservation of long-term economic value of the timber and to capture maximum value from the markets. This is accomplished by ensuring annual harvest schedules target financially mature timber and reforestation activities align with the growing of timber through its life cycle to financial maturity.

Log Sales VolumesVolume
LogsOur sales volume includes fee timber, as well as logs purchased in the open market. Domestic and export logs are sold at market prices to both unaffiliated customers and our internal mills.
Our log sales volumes to unaffiliated customers over the last two years were:
28,250 thousand tons in 2015 decreased 0.5 million cubic meters — 3 percent — from 2014.2018 and
Sales volumes29,420 thousand tons in the West decreased 0.3 million cubic meters — 3 percent — primarily due to lower export sales to China and Korea.
Sales to unaffiliated customers in the South decreased 378 thousand cubic meters — 7 percent — primarily due to lower fee log harvest production.
Sales volumes from Canada increased 95 thousand cubic meters — 16 percent — in 2015. The increase in volume to unaffiliated customers was primarily due to an increase in delivered log sales versus stumpage sales.
Sales volumes from our international operations increased 44 thousand cubic meters — 7 percent — in 2015. The increase in volume was primarily due to increased fiber log sales in Uruguay.
2017.
We sell three grades of logs — domestic grade, domestic fiber and export. Factors that may affect log sales in each of these categories include:
domestic grade log sales — lumber usage, primarily for housing starts and repair and remodel activity, the needs of our own mills and the availability of logs from both outside markets and our own timberlands;
domestic fiber log sales — demand for chips by pulp, containerboard mills, pellet mills and OSB mills; and
export log sales — the level of housing starts in Japan and construction in China.
Our sales volumes include logs purchased in the open market and all our domestic and export logs that are sold to unaffiliated customers or transferred at market prices to our internal mills.

REAL ESTATE, ENERGY AND NATURAL RESOURCES
Our Real Estate & ENR segment maximizes the value of our timberland ownership through application of our asset value optimization (AVO) process and captures the full value of surface and subsurface assets, such as oil, natural gas, minerals and wind and solar resources.
WHAT WE DO
Real Estate
Properties that exhibit higher use value than as commercial timberlands are monetized by our Real Estate business over time. We analyze our existing U.S. timberland holdings using a process we call AVO. We start with understanding the value of a parcel operating as commercial timberlands and then assess the specific real estate attributes of the parcel and its corresponding market. The assessment includes demographics, infrastructure and proximity to amenities and recreation to determine the potential to realize a premium value to commercial timberland. Attributes can evolve over time, and accordingly, the assignment of value and opportunity can change. We continually revisit our AVO assessment of all of our timberland acres.
These properties are acres we expect to sell for recreational, conservation, commercial or residential purposes over time. We will entitle a small amount of acres to support development. Development, outside of entitlement activities, is typically performed by third parties. Some of our real estate activities are conducted through our taxable REIT subsidiary.
Occasionally, we sell a small amount of timberlands acreage in areas where we choose to reduce our market presence, and we can capture a price that exceeds the value derivable from holding and operating as commercial timberlands. These transactions will vary based on factors including the locations and physical characteristics of the timberlands.
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 of buyers to obtain financing, the number of competing properties listed for sale, the seasonal nature of sales (particularly in the Northern states), the plans of adjacent landowners, our expectation of future price appreciation, the timing of the harvesting activities, and the availability of government and not-for-profit funding. In any period, the average sales price per acre will vary based on the location and physical characteristics of parcels sold.
Energy and Natural Resources
We focus on maximizing potential opportunities for oil, natural gas, construction materials, industrial minerals, coal, renewable energy and rights of way easements on our timberlands portfolio and retained mineral interests.
As the owner of mineral rights and interests, we typically do not invest in development or operations but instead enter into contracts with operators granting them the rights to explore and sell energy and natural resources produced from our property in exchange for rents and royalties. Our primary sources of revenue are:
rentals and royalties from the exploration, extraction, production and sale of aggregates and industrial minerals, oil and natural gas, coal and wind energy production;
rental payments from, or sale of, communication, energy and transportation rights of way; and
the occasional sale of mineral assets.
We generally reserve mineral rights when selling timberlands acreage. Some Energy and Natural Resources activities are conducted through our taxable REIT subsidiary.

Wood Products Prices
Prices for commodity wood products — Structural lumber, OSB and Plywood — decreasedincreased in 20152018 from 2014.2017.
In general, the following factors influence pricessales realizations for wood products:
Demand for wood products used in residential and multi-family construction and the repair and remodel of existing homes affects prices. Residential and multi-family construction is influenced by factors such as population growth and other demographics, availability of labor and lots, the level of employment, consumer confidence, consumer income, availability of financing and interest rate levels, and the supply and pricing of existing homes on the market. Repair and remodel activity is affected by the size and age of existing housing inventory and access to home equity financing and other credit.
The availability of supply of commodity building products such as structural lumber, OSB and plywood affects prices. A number of factors can influence supply, including changes in production capacity and utilization rates, weather, raw material supply and availability of transportation.
The North American housing marketDemand for wood products continued to show steady but slow improvementimprove in 2015. Oversupply and weak Canadian currency resulted in generally lower lumber commodity pricing in 2015.2018. The following graphs reflect product price trends for the past five years.

NATURAL RESOURCE AND ENVIRONMENTAL MATTERS
We are subject to a multitude of laws and regulations in the operation of our businesses. We also participate in voluntary certification of our timberlands to assureensure that we sustain their valuesoverall quality, including the protection of wildlife and water quality. Changes in law and regulation, or certification standards, can significantly affect our business.

REGULATIONS AFFECTING FORESTRY PRACTICES
In the United States, regulations established by federal, state and local government agencies to protect water quality, wetlands and wetlandsother wildlife habitat could affect future harvests and forest management practices on some of our timberlands. Forest practice laws and regulations that affect present or future harvest and forest management activities in certain states include:
limits on the size of clearcuts,
requirements that some timber be left unharvested to protect water quality and fish and wildlife habitat,
regulations regarding construction and maintenance of forest roads,
rules requiring reforestation following timber harvest and
various related permit programs.
Each state in which we own timberlands has developed best management practices to reduce the effects of forest practices on water quality and aquatic habitats. Additional and more stringent regulations may be adopted by various state and local governments to achieve water-quality standards under the federal Clean Water Act, protect fish and wildlife habitats, human health, or achieve other public policy objectives.
In Canada, our forest operations are carried out on public timberlands under forest licenses with the provinces. All forest operations in Canada are subject to:
forest practices and environmental regulations, and
license requirements established by contract between us and the relevant province designed to:
- protect environmental values, and
- encourage other stewardship values.
In Canada, 21 member companies of the Forest Products Association of Canada (FPAC), including Weyerhaeusers Canadian subsidiary, announced in May 2010 the signing of a Canadian Boreal Forest Agreement (CBFA) with nine environmental organizations. The CBFA applies to approximately 72 million hectares of public forests licensed to FPAC members and, when fully implemented, iswas expected to lead to the conservation of significant areas of Canadas boreal forest and protection of boreal species at risk, in particular, woodland caribou. While the CBFA mandate came to an end in 2017, CBFA signatories continue to work on management plans with provincial governments, and seek the participation of aboriginal and local communities in advancing the goals of the CBFA. Progress under the CBFA is measured and reported on by an independent auditor.

ENDANGERED SPECIES PROTECTIONS
In the United States, a number of fish and wildlife species that inhabit geographic areas near or within our timberlands have been listed as threatened or endangered under the federal Endangered Species Act (ESA) or similar state laws, such as:including but not limited to:
the northern spotted owl, the marbled murrelet, a number of salmon species, bull trout and steelhead trout in the Pacific Northwest,Northwest;
several freshwater mussel and sturgeon species,species; and
the red-cockaded woodpecker, gopher tortoise, dusky gopher frog, American burying beetle and Northern long-eared bat in the South or Southeast.
Additional species or populations may be listed as threatened or endangered as a result of pending or future citizen petitions or petitions initiated by federal or state agencies. In addition, significant citizen litigation seeks to compel the federal agencies to designate "critical habitat" for ESA-listed species, and many cases have resulted in settlements under which designations will be implemented over time. Such designations may adversely affect some management activities and options. Restrictions on timber harvests can result from:
federal and state requirements to protect habitat for threatened and endangered species,species;
regulatory actions by federal or state agencies to protect these species and their habitat,habitat; and
citizen suits under the ESA.

Such actions could increase our operating costs and affect timber supply and prices in general. To date, we do not believe that these measures have had, and we do not believe that in 20162019 they will have, a significant effect on our harvesting operations. We anticipate that likely future actions will not disproportionately affect Weyerhaeuser as compared with comparable operations of U.S. competitors.
In Canada:
The federal Species at Risk Act (SARA) requires protective measures for species identified as being at risk and for their critical habitat, pursuanthabitat. Pursuant to SARA, Environment Canada continues to identify and assess species deemed to be at risk and their critical habitat, and
habitat.
inIn October 2012, the Canadian Minister of the Environment released a strategy for the recovery of the boreal population of woodland caribou under the SARA. The population and distribution objectives for boreal caribou across Canada are to (1) maintain the current status of existing, self-sustaining local caribou populations and (2) stabilize and achieve self-sustaining status for non-self-sustaining local caribou populations. Critical habitat for boreal caribou is identified for all boreal caribou ranges, except for northern Saskatchewan’s Boreal Shield range (SK1) where additional information is required for that population. Species assessment and recovery plans are developed in consultation with aboriginal communities and stakeholders.
In 2017, the Provinces were required to update the federal government on any progress associated with their draft caribou range plans. These draft plans will be further evaluated in 2019, and any additional information on potential effects to forest harvest operations will be released.

The identification and protection of habitat and the implementation of range plans and land use action plans may, over time, result in additional restrictions on timber harvests and other forest management practices that could increase operating costs for operators of timberlands in Canada. To date, we do not believe that these Canadian measures have had, and we do not believe that in 20162019 they will have, a significant effect on our harvesting operations. We anticipate that likely future measures will not disproportionately affect Weyerhaeuser as compared with similar operations of Canadian competitors.

FOREST CERTIFICATION STANDARDS
We operate in North America under the Sustainable Forestry Initiative(SFI®)(SFI). This is a certification standard designed to supplement government regulatory programs with voluntary landowner initiatives to further protect certain public resources and values. SFI® is an independent standard, overseen by a governing board consisting of:
conservation organizations,
academia,
the forest industry, and
large and small forest landowners.
Ongoing compliance with SFI® may result in some increases in our operating costs and curtailmentreduction of our timber harvests in some areas. There is also is competition from other private certification systems, primarily the Forest Stewardship Council (FSC), coupled with efforts by supporters to further those systems by persuading customers of forest products to require products certified to their preferred system. Certain features of the FSC system could impose additional operating costs on timberland management. Because of the considerable variation in FSC standards, and variability in how those standards are interpreted and applied, if sufficient marketplace demand develops for products made from raw materials sourced from other than SFI-certified forests, we could incur substantial additional costs for operations and be required to reduce harvest levels.

WHAT THESE REGULATIONS AND CERTIFICATION PROGRAMS MEAN TO US
The regulatory and nonregulatorynon-regulatory forest management programs described above have:
increased our operating costs,costs;
resulted in changes in the value of timber and logs from our timberlands,timberlands;
contributed to increases in the prices paid for wood products and wood chips during periods of high demand,demand;
sometimes made it more difficult for us to respond to rapid changes in markets, extreme weather or other unexpected circumstances,circumstances; and
potentially encouraged further reductions in the use of, or substitution of other products for, lumber, oriented strand board, engineered wood products and plywood.
We believe that these kinds ofregulations and programs have not had, and in 20162019 will not have, a significant effect on our total harvest of timber in the United States or Canada. However, these kinds of programs may have such an effect in the future. We expect we will not be disproportionately affected by these programs as compared with typical owners of comparable timberlands. We also expect that these programs will not significantly disrupt our planned operations over large areas or for extended periods.

CANADIAN ABORIGINAL RIGHTS
Many of the Canadian timberlands are subject to the constitutionally protected treaty or common-law rights of aboriginal peoples of Canada. Most of British Columbia (B.C.) is not covered by treaties, and as a result the claims of B.C.’s aboriginal peoples relating to forest resources have been largely unresolved. On June 26, 2014 the Supreme Court of Canada ruled that the Tsilhqot’in Nation holds aboriginal title to approximately 1,900 square kilometers in B.C. This was the first time that the court has declared title to exist based on historical occupation by aboriginal peoples. Many aboriginal groups continue to be engaged in treaty discussions with the governments of B.C., other provinces and Canada.
Final or interim resolution of claims brought by aboriginal groups can be expected to result in:
additional restrictions on the sale or harvest of timber,
potential increase in operating costs and
impact toeffect on timber supply and prices in Canada.
We believe that such claims will not have a significant effect on our total harvest of timber or production of forest products in 20162019, although they may have such an effect in the future. In 2008, FPAC, of which we are a member, signed a Memorandum of Understanding with the Assembly of First Nations, under which the parties agree to work together to strengthen Canadas forest sector through economic-development initiatives and business investments, strong environmental stewardship and the creation of skill-development opportunities particularly targeted to aboriginal youth.

POLLUTION-CONTROL REGULATIONS
Our operations are subject to various laws and regulations, including:
including federal,
state,
provincial and
local pollution controls.
These laws and regulations, as well as market demands, impose controls with regard to:
air, water and land,land;
solid and hazardous waste management,management;
waste disposal,disposal;
remediation of contaminated sites,sites; and
the chemical content of some of our products.

WEYERHAEUSER COMPANY > 2018 ANNUAL REPORT AND FORM 10-K20



Compliance with these laws, regulations and demands usually involves capital expenditures as well as additional operating costs. We cannot easily quantify the future amounts of capital expenditures we might have to make to comply with these laws, regulations and demands or the effects on our operating costs because in some instances compliance standards have not been developed or have not become final or definitive. In addition, it is difficult to isolate the environmental component of most manufacturing capital projects.

WEYERHAEUSER COMPANY > 2015 ANNUAL REPORT AND FORM 10-K19



Our capital projects typically are designed to:
enhance safety,
extend the life of a facility,
increase capacity,lower costs and improve efficiency,
improve reliability,
increase efficiency,capacity,
facilitate raw material changes and handling requirements,
increase the economic value of assets or products, and
comply with regulatory standards.
We had capital expenditures of $23 million relating primarily to environmental compliance in 2015. Based on our understanding of current regulatory requirements in the U.S. and Canada, we expect no material capital expenditures relating primarily to environmental compliance in 2016.

ENVIRONMENTAL CLEANUP
We are involved in the environmental investigation or remediation of numerous sites. Of these sites:
we may have the sole obligation to remediate,
we may share that obligation with one or more parties,
several parties may have joint and several obligations to remediate orand
we may have been named as a potentially responsible party for contaminated sites, including those designated as U.S. Superfund sites.
Our liability with respect to these various sites ranges from insignificant to substantial. The amount of liability depends on:on the:
the quantity, toxicity and nature of materials at the site,site; and
the number and economic viability of the other responsible parties.
We spent approximately $7$13 million in 20152018 and expect to spend approximately $7$6 million in 20162019 on environmental remediation of these sites.
It is our policy to accrue for environmental-remediation costs when we:
determine it is probable that such an obligation exists and
can reasonably estimate the amount of the obligation.
We currently believe it is reasonably possible that our costs to remediate all the identified sites may exceed our current accruals of $37 million. The excess amounts required$62 million. Based on currently available information and analysis, remediation costs for all identified sites may be insignificant or could range, in the aggregate,exceed our existing reserves by up to $116 million over several years.$126 million. This estimate of the upper end of the range of reasonably possible additional costs is much less certain than the estimates we currently are using to determine how much to accrue. The estimate of the upper range also uses assumptions less favorable to us among the range of reasonably possible outcomes.

REGULATION OF AIR EMISSIONS IN THE U.S.
The United States Environmental Protection Agency (EPA) has promulgated regulations for air emissions from:
pulp and paper manufacturing facilities,
wood products facilities and
industrial boilers.
These regulations cover:
hazardous air pollutants that require use of maximum achievable control technology (MACT); and
controls and/or monitoring for pollutants that contribute to smog, haze and more recently, greenhouse gases.
Between 2011 and 2015, the EPA issued three related portions of new MACT standards for industrial boilers and process heaters. In July 2016, a court decision was issued that requires EPA had completed a technology and residual risk review for MACTto re-issue certain of the emissions standards. Some of these re-issued emissions standards will be applicable to pulping and bleaching operations at pulp and paper manufacturing facilities in 2012 and in 2014 had issued a revised New Source Performance Standard for kraft pulpsmall number of our wood products mills. These latter two rules apply on a project specific basisBecause we do not know specifically how or when certain thresholds are exceeded; as a result,the EPA will implement the final court decision, we cannot predict whether or when those rulesthe emission standard revisions may have a material impacteffect on future projects. Regarding other recent final actions by the EPA, weregulatory compliance costs at our mills. We do not expect any material expenditures in 20162019 necessary to comply with MACT standards.
The EPA must still promulgate:
technology and residual risk review standards for additional operations at pulp and paper manufacturing facilities and
promulgate supplemental MACT standards for plywood, lumber and composite wood products facilities.
We cannot currently quantify the amount of capital we will need in the future to comply with new regulations being developed by the EPA because final rules have not been promulgated.
In 2010, the EPA issued a final greenhouse gas rule limiting the growth of emissions from new projects meeting certain thresholds. On June 23, 2014, the US Supreme Court issued a decision that removed potential applicability of the underlying 2010 regulations based solely on greenhouse gas emissions and limited application of the rule’s technology requirements to larger emission sources as a result of new emissions from non-greenhouse gas pollutants. As a result of this Supreme Court ruling, EPA is expected to issueproposed a new regulationsregulation in 2016 to set thresholds for when the greenhouse gas technology requirements apply if the non-greenhouse gas emissions trigger the rule in the first instance. EPA to date has not finalized this regulation. The impacteffect of the Supreme Court ruling is to end the potential applicability of the technology requirements for our smaller manufacturing operations and limit the applicability for our other operations.
In 2015, the EPA issued an extensive regulatory program for new and existing electric utility generating units to scale back emissions of greenhouse gas carbon dioxide (CO2) arising from fossil fuel use to generate electricity. EPA also proposed additional, supplemental regulations related to how states and federal agencies may implement the requirements finalized in 2015. ThisSubsequent actions include in 2016 a US Supreme Court stay of the 2015 rule pending resolution of lower court challenges to the rule, in 2017 the withdrawal by EPA of the proposed supplemental regulations and a proposal to rescind the 2015 final rule, and in 2018 an EPA proposal of a substantially different replacement rule. Depending on the final outcomes, this regulatory program potentially will have indirect impactseffects on our operations, such as from rising purchased electricity prices or from mandated energy demand reductions that could apply to our mills and other facilities that we operate. We are evaluatingcontinue to track and evaluate the regulationslitigation and additional proposalsregulatory development but are not able to predict whether the regulations, when complete and implemented, will have a material impacteffect on our operations.

 WEYERHAEUSER COMPANY > 20152018 ANNUAL REPORT AND FORM 10-K 2021




We use significant biomass for energy production at our mills. EPA is currently working on rules regarding regulation of biomass emissions.
The impacteffect of these greenhouse gas and biomass rules, as well as recent court decisions, on our operations remains uncertain.
To address concerns about greenhouse gases as a pollutant, we:
closely monitor legislative, regulatory and scientific developments pertaining to climate change;
adopted in 2006, as part of the Company'scompany's sustainability program, a goal of reducing greenhouse gas emissions by 40 percent by 2020 compared with our emissions in 2000, assuming a comparable portfolio and regulations;
determined to achieve this goal by increasing energy efficiency and using more greenhouse gas-neutral, biomass fuels instead of fossil fuels; and
reduced greenhouse gas emissions by approximately 2544 percent considering changes in the asset portfolio according to 20142017 data, compared to our 2000 baseline.
Additional factors that could affect regulation of greenhouse gas emissions in the future include:
policy proposals by federal or state governments regarding regulation of greenhouse gas emissions,
Congressional legislation regulating or taxing greenhouse gas emissions within the next several years and
establishment of a multistate or federal greenhouse gas emissions reduction trading systemssystem with potentially significant implications for all U.S. businesses.
We believe these developments have not had, and in 20162019 will not have, a significant effect on our operations. Although these measures could have a material adverse effect on our operations in the future, we expect that we will not be disproportionately affected by these measures as compared with owners of comparable operations. We maintain an active forestry research program to track and understand any potential effect from actual climate change related parameters that could affect the forests we own and manage and do not anticipate any disruptions to our planned operations.

REGULATION OF AIR EMISSIONS IN CANADA
In addition to existing provincial air quality regulations, the Canadian federal government has proposed an air quality management system (AQMS) as a comprehensive national approach for improving air quality in Canada. The federal proposed AQMS includes:
ambient air quality standards for outdoor air quality management across the country,country;
a framework for air zone air management within provinces and territories that targets specific sources of air emissions,emissions;
regional airsheds that facilitate coordinated action across borders,borders;
industrial sector based emission requirements that set a national base level of performance for major industries in Canada,Canada; and
improved intergovernmental collaboration to reduce emissions from the transportation sector.
In 2016, Environment Canada is developingreleased the Pan-Canadian Framework on Clean Growth and Climate Change, a Greenhouse"Greenhouse Gas Emission Framework that is expected to be proposed in 2016 with implementation in 2020.Framework." The framework will put in place a national, sector-based greenhouse gas reduction program applicable to a number of industries, including pulp and paper manufacturing.ours.
All Canadian provincial governments:
have greenhouse gas reporting requirements,,
are working on reduction strategies, and
together with the Canadian federal government, are considering new or revised emission standards.
In addition, British Columbia has adopted a carbon tax and Alberta has a mandatory GHGgreenhouse gas emission reduction regulation. Our Grande Prairie, Alberta cellulose fiber mill generates and sells carbon credits.
We believe these measures have not had, and in 2019 will not have, a significant effect on our operations. Although these measures could have a material adverse effect on our operations in the future, we expect that we will not be disproportionately affected by these measures as compared with owners of comparable operations. We also expect that these measures will not significantly disrupt our planned operations.

REGULATION OF WATER
In the U.S., as a result of litigation under the federal Clean Water Act, additional federal or state permits are now required in some states for the application of pesticides, including herbicides, on timberlands. Those permits have entailed payment of additional costs. In 2015, federal regulatory agencies adopted rules that potentially expand the definition of waters subject to federal Clean Water Act jurisdiction, which could increase the scope and number of permits required for forestry-related activities and entail additional costs for Weyerhaeuser and other forest landowners in the U.S. Those rules were challenged in various federal courts by numerous parties and states, and a nationwide injunction was issued against the rule by the Sixth Circuit Court of Appeals, but was dissolved in 2018 due to action by the U.S. Supreme Court. Other injunctions still block the rule in several states. In January 2018, federal agencies took regulatory action to further delay the 2015 rules from going into effect until February 2020; however, that action was enjoined in September 2018 by a South Carolina court. Challenges to the substance of the 2015 rule are being pursued in other pending cases challenging the 2015 rules. Meanwhile, the federal agencies have proposed repeal of the 2015 rules entirely and replacement of them with a new rule, which is now open for public comment. We are not able to predict the ultimate resolution of these pending legal and regulatory actions.
In 2016, Washington State Department of Ecology (WA DOE) adopted human health-based water quality criteria. The EPA subsequently promulgated its own water quality standards for Washington state for the protection of human health for certain pollutants. It is unclear what effect, if any, these rules will have on our manufacturing operations in Washington state.
In addition, in 2013, amendments to the Canadian Federal Fisheries Act came into force. These amendments changed the focus from habitat protection to fisheries protection and increased penalties. We expect further changes to these regulations subsequent to review and regulatory consultations that took place in 2016, but we cannot predict the scope or potential effect, if any, on our operations.
We believe the above developments have not had, and in 20162019 will not have, a significant effect on our operations. Although these measures could have a material adverse effect on our operations in the future, we expect that we will not be disproportionately affected by these measures as compared with owners of comparable operations. We also expect that these measures will not significantly disrupt our planned operations.

REGULATION OF AIR EMISSIONS IN POLAND AND URUGUAY
The European Unions Clean Air Programme includes new air quality objectives that Poland and other European Union countries will implement through 2030. Some provinces in Uruguay have established air quality monitoring networks and ambient air objectives have been proposed for the region where our Los Piques mill is located.
We believe these measures have not had, and in 2016 will not have, a significant effect on our operations. Although these measures could have a material adverse effect on our operations in the future, we expect that we will not be disproportionately affected by these measures as compared with owners of comparable operations. We also expect that these measures will not significantly disrupt our planned operations.

REGULATION OF WATER
In the U.S., as a result of litigation under the federal Clean Water Act, additional federal or state permits are now required in some states for the application of pesticides, including herbicides, on timberlands. Those permits have entailed additional costs. In addition, there are continuing regulatory developments and continuing litigation in the federal courts that may result in permit requirements for pollution discharges from forest roads and other drainage features on timberland, which would entail additional costs for forest landowners including Weyerhaeuser. Finally, federal regulatory agencies adopted rules in 2015 that potentially expand the definition of waters subject to federal Clean Water Act jurisdiction, which could increase the scope and number of permits required for forestry-related activities and entail additional costs for Weyerhaeuser and other forest landowners in the U.S. Those rules have been challenged in federal court by multiple parties and states and an injunction has been entered that prevents them from going into effect. We are not able to predict the ultimate resolution of these pending legal actions.
In August 2014 EPA issued a final regulation on thermal cooling water intakes for the protection of aquatic resources. The final rule is not expected to have a material impact although the technology requirements to protect aquatic resources outlined in the rule may be applied on a case-by-case basis when water permits are renewed.

 WEYERHAEUSER COMPANY > 20152018 ANNUAL REPORT AND FORM 10-K 2122



In 2015, Washington State Department of Ecology (WA DOE) and the regional federal EPA proposed rules to update the Human Health Water Quality Criteria for the protection of human health. It is unclear what effect, if any, the proposed rules will have on our manufacturing operations in Washington State.
In addition:
In 2013, amendments to the Canadian Federal Fisheries Act came into force. These amendments change the focus from habitat protection to fisheries protection and increase penalties. We expect further changes to these regulations in 2016, but we cannot predict the scope or potential impact, if any, on our operations.
Uruguay's national policy for water includes regulation of river basin planning, management and water use permits. Wastewater discharge authorization is required for industry, including our Los Piques mill.
In response to an European Union Water Framework Directive, in 2015 Polish authorities announced their intention to develop a water management plan to reduce total nitrogen and phosphorous loads in municipal waste water by 75 percent. The plan could impact our Poland facility, although it is unclear what effect, if any, the water management plan may have on our operation in Poland until the plan is complete.
We believe the above developments have not had, and in 2016 will not have, a significant effect on our operations. Although these measures could have a material adverse effect on our operations in the future, we expect that we will not be disproportionately affected by these measures as compared with owners of comparable operations. We also expect that these measures will not significantly disrupt our planned operations.

POTENTIAL CHANGES IN POLLUTION REGULATION
State governments continue to promulgate total maximum daily load (TMDL) requirements for pollutants in water bodies that do not meet state or EPA water quality standards. State TMDL requirements may:may set:
set limits on pollutants that may be discharged to a body of water; or
set additional requirements, such as best management practices for nonpoint sources, including timberland operations, to reduce the amounts of pollutants.
It is not possible to estimate the capital expenditures that may be required for us to meet pollution allocations across the various proposed state TMDL programs until a specific TMDL is promulgated.
In Canada, various levels of government have been working to address water issues including use, quality and management. Recent areas of focus include water allocation, regional watershed protection, protection of drinking water, water pricing and a national water quality index.

RISK FACTORS
We are subject to various risks and events that could adversely affect our business, our financial condition, our results of operations, our cash flows and the price of our common stock.
You should consider the following risk factors, in addition to the information presented elsewhere in this report, particularly in Our Business - Who We Are, Our Business - What We Do, Our Business - Natural Resources and Environmental Matters, Forward-Looking Statements and "Management's Discussion and Analysis of Financial Condition and Results of Operations" as well as in the filings we make from time to time with the SEC, in evaluating us, our business and an investment in our securities.
The risks discussed below are not the only risks we face. Additional risks not currently known to us or that we currently deem immaterial also may adversely affect our business.

RISKS RELATED TO OUR INDUSTRIES AND BUSINESSINDUSTRY

MACROECONOMIC CONDITIONS
The industries in which we operate are sensitive to macroeconomic conditions and consequently are highly cyclical.
The overall levels of demand for the products we manufacture and distribute reflect fluctuations in levels of end-user demand, which consequently impactaffect our sales and profitability. End-user demand depends in large part on general macroeconomic conditions, both in the U.S. and globally, as well as on local economic conditions. Current economic conditions in the United States reflect growth at or below historical trendsenhanced by tax cuts passed in 2018, the effect of which may be adversely affected by increases in interest rates and general business uncertainty.other factors in 2019. Global economic conditions reflect issues such as inflationvolatile and slowingsporadic growth in emerging countries. The constructioncountries and homebuilding industries continue to slowly recover from the severe downturn caused by the overall collapse of credit markets and recession of 2009. However, construction activity remains below pre-recession and trend levels. Our Wood Products segment is highly dependent on the strength of the homebuilding industry. The decline in home construction activity due to the recession resulted in depressed prices of and reduced demand for wood products and building materials. This resulted in lower prices and demand for logs and reduced harvests in our Timberlands segment.uncertainty over international trade. The length and magnitude of industry cycles vary over time, both by market and by product, but generally reflect changes in macroeconomic conditions and levels of industry capacity. Those conditions have improved since the recession, but ifAny decline or stagnation in macroeconomic conditions do not continuecould cause us to improve we could experience lower sales volumesvolume and smallerreduced margins.

COMMODITY PRODUCTS
Many of our products are commodities that are widely available from other producers.
Because commodity products have few distinguishing properties from producer to producer, competition for these products is based primarily on price, which is determined by supply relative to demand and competition from substitute products. In addition, prices for our products are affected by many other factors outside of our control. As a result, we have little influence over the timing and extent of price changes, which often are volatile. Our profitability with respect to these products depends, in part, on managing our costs, particularly raw material, labor (including contract labor) and energy costs, which represent significant components of our operating costs and can fluctuate based upon factors beyond our control. Both sales and profitability of our products are subject to volatility due to market forces beyond our control.

INDUSTRY SUPPLY OF LOGS AND WOOD PRODUCTS AND PULP
Excess supply of logs and wood products may adversely affect prices and margins.
Oversupply of productsOur industry may result from producers introducing new capacity for manufactured products or increasingincrease harvest levels, in responsewhich could lead to favorable short-term pricing trends. Industry suppliesan oversupply of pulp are also influenced by global productionlogs. Wood products producers may likewise expand manufacturing capacity, which has grown in recent years and is expectedcould lead to continuean oversupply of manufactured wood products. Any increase of industry supply to grow. Continuation of these factorsour markets could adversely affect our sales volumesprices and margins.

HOMEBUILDING MARKET AND ECONOMIC RISKS
High unemployment, low demand and low levels of consumer confidence can adversely affect our business and results of operations.
Our business is dependent upon the health of the U.S. housing market. Demand for homes is sensitive to changes in economic conditions such as the level of employment, consumer confidence, consumer income, the availability of financing and interest rate levels. The legacy of the housing bubble, its collapse and ensuing credit crisis was tightened credit requirements and a reduced number of mortgage loans available for financing home purchases. Although credit conditions have eased, they remain more restrictive than prior to the housing bubble. DemandOther factors that could limit or adversely affect demand for new homes, also has been adversely affected byand hence demand for our products, include factors such as unemployment and lower job participation, limited wage growth, increases in non-mortgage consumer debt, any weakening in consumer confidence, and weak consumer confidence. Additionally, rising student loan debt among younger adults is limiting access to mortgage financing and home ownership. Foreclosureany increase in foreclosure rates and distress sales of houses, have fallen significantly and are less of an impact compared to the years immediately following the housing collapse.houses.
Homebuyers’ ability to qualify for and obtain affordable mortgages could be affected by changes in interest rates, changes in home loan underwriting standards and government sponsored entities and private mortgage insurance companies supporting the mortgage market.
Access to affordable mortgage financing is critical to the health of the U.S. housing market. Generally, increases in interest rates make it more difficult for home buyers to obtain mortgage financing, which could negatively affect demand for housing and, in turn, negatively affect demand for our wood products. After an extended period during which the U.S. Federal Reserve kept its benchmark interest rate at historically low levels, it began raising rates again in 2016 and continued through 2018. The federal government has historically had a significant role in supporting mortgage lending through its sponsorshipnumber and extent of Fannie Mae and Freddie Mac.

DeteriorationTRANSPORTATION
We depend on third parties for transportation services and any disruptions in economic conditionsthe availability of transportation or increases in transportation costs could materially adversely affect our business and operations.
Our business depends heavily on the credit marketsavailability of third-party service providers for the transportation of our wood products and wood fiber; we are therefore materially affected by the availability and cost of these services. Any significant increase in the operating costs to our service providers, including without limitation the cost of fuel or labor, could have a material negative effect on our financial results by increasing the cost of these services to us, as well as result in an overall reduction in the availability of these services altogether.
Our third-party transportation providers are also subject to several events outside of their control, such as disruption of transportation infrastructure, labor issues and natural disasters. Any failure of a third-party transportation provider to timely deliver our products, including delivery of our wood products and wood fiber to our customers and delivery of wood fiber to our mills, could harm our supply chain, negatively affect our customer relationships and have a material adverse effect on our financial condition, results of operations and our reputation.

RISKS RELATED TO OUR BUSINESS
MANAGING COMMERCIAL TIMBERLANDS RISKS
Our ability to harvest and deliver timber may be subject to limitations which could adversely affect our results of operations.
Our primary assets are our timberlands. Weather conditions, timber growth cycles, access to capital.
Upset financial or credit market conditions can impair the companys ability to borrow money or otherwise access credit markets on terms acceptable to us, whichlimitations, and availability of contract loggers and haulers may among other impacts, reduceadversely affect our ability to take advantageharvest our timberlands. Other factors that may adversely affect our timber harvest include damage to our standing timber by fire or by insect infestation, disease, prolonged drought, flooding, severe weather and other natural disasters. Changes in global climate conditions could intensify one or more of these factors. Although damage from such causes usually is localized and affects only a limited percentage of standing timber, there can be no assurance that any damage affecting our timberlands will in fact be limited. As is common in the forest products industry, we do not maintain insurance coverage for damage to our timberlands. Our revenues, net income and cash flow from operations are dependent to a significant extent on the pricing of our products and our continued ability to harvest timber at adequate levels. Therefore, if we were to be restricted from harvesting on a significant portion of our timberlands for a prolonged period of time, or if material damage to a significant portion of our standing timber were to occur, we could suffer materially adverse effects to our results of operations.
Our timber harvest levels may be affected by acquisitions of additional timberlands, sales of existing timberlands and shifts in harvest from one region to another. Future timber harvest levels may also be affected by our ability to timely and effectively replant harvested areas, which depends on several factors including changes in estimates of long-term sustainable yield because of silvicultural advances, natural disasters, fires, pests, insects and other hazards, regulatory constraints, availability of logging contractors and other factors beyond our control.
Timber harvest activities are also subject to a number of federal, state and local regulations pertaining to the protection of fish, wildlife, water and other resources. Regulations, re-interpretations and litigation can restrict timber harvest activities and increase costs. Examples include federal and state laws protecting threatened, endangered and “at-risk” species, harvesting and forestry road building activities that may be restricted under the U.S. Federal Clean Water Act, state forestry practices laws, laws protecting aboriginal rights, and other similar regulations.
Our estimates of timber inventories and growth rates may be inaccurate and include risks inherent in calculating such estimates, which may impair our ability to realize expected revenues.
Whether in connection with managing our existing timberland portfolio or assessing potential timberland acquisitions, we make and rely on important estimates of merchantable timber inventories. These include estimates of timber inventories that may be lawfully and economically harvested, timber growth rates and end-product yields. Timber growth rates and yield estimates are developed by forest biometricians and other experts using statistical measurements of tree samples on given property. These estimates are central to forecasting our anticipated timber harvests, revenues and expected cash flows. While the company has confidence in its timber inventory processes and the professionals in the field who administer it, growth and expansion opportunities. Similarly,yield estimates are inherently inexact and uncertain. If these estimates are inaccurate, our customersability to manage our timberlands in a sustainable or profitable manner may be unablecompromised, which may cause our results of operations and our stock price to borrow money to fund their operations. Similarly, deterioratingbe adversely affected.

Our operating results and cash flows will be materially affected by supply and demand for timber.
A variety of factors affect prices for timber, including available supply, changes in economic conditions that affect demand, the level of domestic new construction and remodeling activity, interest rates, credit availability, population growth, weather conditions and pest infestation, and other factors. These factors vary by region, by timber type (i.e., sawlogs or volatile market conditionspulpwood logs) and by species.
Timber prices are affected by changes in demand on a local, national and international level. The closure of a mill in a region where we own timber could have ana material adverse effect on demand in that region, and therefore pricing. For example, as the demand for paper continues to decline, closures of pulp mills in some of our operating regions have adversely affected the regional demand for pulpwood and wood chips. Another example involves our export of logs to Asia. While recent demand from Asian markets has remained steady, some Asian markets, particularly in China, have a history of significant volatility. A decrease in demand for logs from one or more Asian markets could have a negative effect on log and lumber prices.
Timber prices are also affected by changes in timber availability at the local, national and international level. Our timberland ownership is concentrated in Alabama, Arkansas, Louisiana, Mississippi, North Carolina, Oklahoma, Oregon and Washington. In some of these states, much

WEYERHAEUSER COMPANY > 2018 ANNUAL REPORT AND FORM 10-K26



of the timberland is privately owned. Increases in timber prices often result in substantial increases in harvesting on private timberlands, including lands not previously made available for commercial timber operations, causing a short-term increase in supply that moderates such price increases. In western states such as Oregon and Washington, where a greater proportion of timberland is government-owned, any substantial increase in timber harvesting from government-owned land could significantly reduce timber prices. Any decrease in the demand from our log export markets could also result in significant downward pressure on timber prices, particularly in the western region. On a local level, timber supplies can fluctuate depending on factors such as changes in weather conditions and harvest strategies of local timberland owners, as well as occasionally high timber salvage efforts due to events such as pest infestations, fires or other natural disasters.

Timberlands make up a significant portion of our business portfolio.
Our real property holdings are primarily timberlands and we may make additional timberlands acquisitions in the future. As the owner and manager of approximately 12.2 million acres of timberlands, we are subject to the risks that are inherent in concentrated real estate investments. A downturn in the real estate industry generally, or the timber or forest products industries specifically, could reduce the value of our properties and adversely affect our results of operations. Such a downturn could also adversely affect our customers and suppliers and theirreduce the demand for our products, as well as our ability to purchaseexecute upon our products or sell products to us.strategy of selling nonstrategic timberlands and timberland properties that have higher and better uses at attractive prices. These risks may be more pronounced than if we diversified our investments outside of real property holdings.

Additionally, we may be required to make significant unplanned capital expenditures. Although some risks are not insurable and some coverage is limited, we purchase insurance on our manufacturing facilities for damage from fires, floods, windstorms, earthquakes, equipment failures and boiler explosions. Such insurance may not be sufficient to recover all of our damages.
Some of our wood products are vulnerable to declines in demand due to competing technologies or materials.
Our products may compete with nonfiber-basednon-fiber based alternatives or with alternative products in certain market segments. For example, plastic, wood/plastic or composite materials may be used by builders as alternatives to theour wood products produced by our Wood Products businesses such as lumber, veneer, plywood and oriented strand board. Changes in prices for oil, chemicals and wood-based fiber can change the competitive position of our products relative to available alternatives and could increase substitution of those products for our products. If use of these or other alternative products grows, demand for and pricing of our products could be adversely affected.

CHANGES IN PRODUCT MIX OR PRICING
Our results of operations and financial condition could be materially adversely affected by changes in product mix or pricing.
Our results may be materially adversely affected by a change in our product mix or pricing. Some of our wood products, such as lumber, veneer, plywood and oriented strand board, are commodities and are subject to fluctuations in market pricing. If pricing on our commodity products decreases and if we are not successful in increasing sales of higher-priced, higher-value products, or if we are not successful in implementing previously announced or future price increases, or in our plans to increase sales of higher-priced, higher-value products, or if there are delays in acceptance of price increases or failure of customers to accept higher-priced products, our results of operations and financial condition could be materially and adversely affected.

Historically, Canada has been a significant source of lumber for the U.S. market, particularly in the new home construction market. We produce lumber in our Canadian mills, but the bulk of our production is in the U.S. The Softwood Lumber Agreement (SLA) between Canada and the U.S., originally signed in October 2006, expired in October 2015. The 2006 SLA required Canadian softwood lumber facilities, including our mills, to pay an export tax when the price of lumber is at or below a threshold price. We are not able to predict when or if a new agreement will be reached or, if reached, what the terms of the agreement would be. We could experience downward pressure on timber and lumber prices caused by Canadian lumber imports.
Another emerging form of competition is between brands of sustainably produced products; customer demand for certain brands could reduce competition among buyers for our products or cause other adverse effects.
In North America, our forests are third party-certified toWe have adopted the Sustainable Forestry Initiative (SFI®) standard.(SFI) standard for wood fiber supplied to our manufacturing facilities, both from our timberlands and from third-party suppliers. Some of our customers have expressed a preference in certain of our product lines for products made from raw materials sourced from forests certified to different standards, including standards of the Forest Stewardship Council (FSC). If and to the extent thatcustomer preference for a sustainability standard other than SFI® increases, or if the SFIstandard falls into disfavorbecomes a customer requirement,, there may be reduced demand and lower prices for our products relative to competitors who can supply products sourced from forests certified to competing certification standards. If we seek to comply with such other standards, we could incur materially increased costs for our operations or be required to modify our operations, such as reducing harvest levels. FSC, in particular, employs standards that are geographically variable and could cause a material reduction in the harvest levels of some of our timberlands, most notably in the Pacific Northwest.

STRATEGIC INITIATIVES
Our business and financial results may be adversely impacted if we are unable to successfully execute on important strategic initiatives.
There can be no assurance that we will be able to successfully implement important strategic initiativesfully offset the effects of higher raw material or energy costs through price increases, productivity improvements, cost-reduction programs or hedging arrangements.

RISKS RELATED TO CAPITAL MARKETS

CAPITAL MARKETS
Deterioration in accordance with our expectations, which may result in an adverse impact on our businesseconomic conditions and financial results. These strategic initiatives are designed to improve our results of operations and drive long-term shareholder value, and include, among others: maximizing cash flow through operational excellence; reducing costs to achieve industry-leading cost structure; and innovating in higher-margin products.
We may be unsuccessful in carrying out our acquisition strategy.
We intend to strategically pursue acquisitions of timberland properties when market conditions warrant. As with any investment, our acquisitions 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 or proceeds from asset dispositions, or any combination thereof. Our inability to finance future acquisitions on favorable termscapital markets could adversely affect our resultsaccess to capital.
Challenging market conditions could impair the companys ability to raise debt or equity capital or otherwise access capital markets on terms acceptable to us, which may, among other effects, reduce our ability to take advantage of operations.growth and expansion opportunities. Likewise, our customers and suppliers may be unable to raise capital to fund their operations, which could, in turn, adversely affect their ability to purchase products or sell products to us.

CREDIT RATINGS
Changes in credit ratings issued by nationally recognized rating organizations could adversely affect our cost of financing and have an adverse effect on the market price of our securities.
Credit rating agencies rate our debt securities on factors that include our operating results and balance sheet, actions that we take, their view of the general outlook for our industry and their view of the general outlook for the economy. Ratings decisions by these agencies include maintaining, upgrading or downgrading our current rating, as well as placing the company on a "watch list" for possible future ratings actions. Any downgrade of our credit rating, or decision by a rating agency to place us on a "watch list" for possible future downgrading could have an adverse effect on our ability to access credit markets, increase our cost of financing, and have an adverse effect on the market price of our securities.

CAPITAL REQUIREMENTS AND ACCESS TO CAPITAL
OurAccess to capital required for our operations require substantial capital.may be costly or impaired.
Our businesses require substantial capital for expansion and for repair or replacement of existing facilities or equipment. Although we maintain our production equipment with regular scheduled maintenance, key pieces of equipment may need to be repaired or replaced periodically. The costs of repairing or replacing such equipment and the associated downtime of the affected production line could have a material adversesignificant effect on our financial condition, results of operations and cash flows.
While we believe our capital resources will be adequate to meet our current projected operating needs, capital expenditures and other cash requirements, if for any reason we are unable to provideaccess capital for our operating needs, capital expenditures and other cash requirements on acceptable economic terms, or at all, we could experience a material adverse effect on our business, financial condition, results of operations and cash flows.

FOREIGN CURRENCY
We will be affected by changes in currency exchange rates.
We have manufacturing operations in Canada. We are also an exporter and compete with global producers of products very similar to ours. Therefore, we are affected by changes in the strength of the U.S. dollar, particularly relative to the Canadian dollar, euro, yuan and yen, and the strength of the euro relative to the yen. Changes in exchange rates could materially and adversely affect our sales volume, margins and results of operations.

RISKS RELATED TO LEGAL, REGULATORY AND TAX

ENVIRONMENTAL LAWS AND REGULATIONS
We could incur substantial costs as a result of compliance with, violations of, or liabilities under applicable environmental laws and other laws and regulations.
We are subject to a wide range of general and industry-specific laws and regulations relating to the protection of the environment, including those governing:
air emissions,
wastewater discharges,
harvesting and other silvicultural activities,
forestry operations and endangered species habitat protection,
surface water management,
the storage, usage, management and disposal of hazardous substances and wastes,
the cleanup of contaminated sites,
landfill operation and closure obligations,
building codes, and
health and safety matters.
We have incurred, and we expect to continue to incur, significant capital, operating and other expenditures complying with applicable environmental laws and regulations and as a result of remedial obligations. We also could incur substantial costs, such as civil or criminal fines,

WEYERHAEUSER COMPANY > 2015 ANNUAL REPORT AND FORM 10-K26



sanctions and enforcement actions (including orders limiting our operations or requiring corrective measures, installation of pollution control equipment or other remedial actions), cleanup and closure costs, and third-party claims for property damage and personal injury as a result of violations of, or liabilities under, environmental laws and regulations.
As the owner and operator of real estate, we may be liable under environmental laws for cleanup, closure and other damages resulting from the presence and release of hazardous substances on or from our properties or operations. In addition, surface water management regulations may present liabilities and are subject to change. The amount and timing of environmental expenditures is difficult to predict, and in some cases, our liability may exceed forecasted amounts or the value of the property itself. The discovery of additional contamination or the imposition of additional cleanup obligations at our sites or third-party sites may result in significant additional costs.
We also lease some of our properties to third-party operators for the purpose of exploring, extracting, developing and producing oil, gas, rock and other minerals in exchange for fees and royalty payments. These activities are also subject to federal, state and local laws and regulations. These operations may create risk of environmental liabilities for any unlawful discharge of oil, gas or other chemicals into the air, soil or water. Generally, these third-party operators indemnify us against any such liability, and we require that that they maintain liability insurance during the term of our lease with them. However, if for any reason our third-party operators are not able to honor their indemnity obligation, or if the required liability insurance were not in effect, then it is possible that we could be deemed responsible for costs associated withenvironmental liability caused by such third-party operators.
Any material liability we incur as a result of activities conducted on our properties by us or by others with whom we have a business relationship could adversely affect our financial condition or preclude us from making capital expenditures that otherwise would benefit our business.condition.
We also anticipate public policy developments at the state, federal and international level regarding climate change and energy access, security and competitiveness. We expect these developments to address emission of carbon dioxide, renewable energy and fuel standards, and the monetization of carbon. Compliance with regulations that implement new public policy in these areas might require significant expenditures. These developments may also include mandated changes to energy use and building codes which could affect our homebuilding practices. Enactment of new environmental laws or regulations or changes in existing laws or regulations, or the interpretation of these laws or regulations, might require significant expenditures. We also anticipate public policy developments at the state, federal and international level regarding taxes and a number of other areas that could require significant expenditures.
Changes in global or regional climate conditions and governmental response to such changes at the international, U.S. federal and state levels may affect our operations or our planned or future growth activities.
There continue to be numerous international, U.S. federal and state-level initiatives and proposals to address domestic and global climate issues. Within the U.S. and Canada, some of these proposals would (and have in some Canadian provinces) regulate and/or tax the production of carbon dioxide and other “greenhouse gases”greenhouse gases to facilitate the reduction of carbon compound emissions into the atmosphere and provide tax and other incentives to produce and use “cleaner”cleaner energy. Climate change impacts,effects, if they occur, and governmental initiatives, laws and regulations to address potential climate concerns, could increase our costs and have a long-term adverse impacteffect on our businesses and results of operations. Future legislation or regulatory activity in this area remains uncertain, and its impacteffect on our operations is unclear at this time. However, it is possible that legislation or government mandates, standards or regulations intended to mitigate or reduce carbon compound or greenhouse gas emissions or other climate change impactseffects could adversely affect our operations. For example, such activities could limit harvest levels or result in significantly higher costs for energy and other raw materials. Because our manufacturing operations depend upon significant amounts of energy and raw materials, these initiatives could have an adverse impacteffect on our results of operations and profitability.

CURRENCY EXCHANGE RATESLEGAL MATTERS
We will be affected by changesare involved in currency exchange rates.
We have manufacturing operations in Canada, Polandvarious environmental, regulatory, product liability and Uruguay. We are also a large exporterother legal matters, disputes and compete with global producers of products very similar to ours. Therefore, we are affected by changes in the strength of the U.S. dollar, particularly relative to the Canadian dollar, euro and yen, and the strength of the euro relative to the yen. Changes in exchange rates could materially and adversely affect our sales volumes, margins and results of operations.

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

PEOPLE
Our business is dependent upon attracting, retaining and developing key personnel.
We believe that our success depends, to a significant extent, upon our ability to attract, retain and develop key senior management and operations management personnel. Our failure to recruit, retain, and develop key personnel could adversely affect our financial condition or results of operations.

TRANSPORTATION
We depend on third parties for transportation services and increases in costs and disruptions in the availability of transportation could materially adversely affect our business and operations.
Our business depends on the transportation of a large number of products, both domestically and internationally. We rely primarily on third parties for transportation of the products we manufacture or distribute as well as delivery of our raw materials. A significant portion of the goods we manufacture and raw materials we use are transported by marine, rail and truck, each of which is highly regulated. In addition, each has historically been subject to periodic disruption due to labor issues.
If any of our third-party transportation providers were to fail to deliver the goods we manufacture or distributeconcluded in a timely manner we may be unableadverse to sell those products at full value, or at all. Similarly, if any of these providers were to fail to deliver raw materials to us in a timely manner, we may be unable to manufacture our products in response to customer demand. In addition, if any of these third parties were to cease operations or cease doing business with us, we may be unable to replace them at reasonable cost. Our third-party transportation providers are also subject to events outside of their control, such as disruption of transportation infrastructure due to labor issues or natural disasters.
Any failure of a third-party transportation provider to deliver raw materials or finished products in a timely mannerinterests, could harm our reputation, negatively affect our customer relationships and have a material adverse effect on our financial conditioncondition.
We are, from time to time, involved in a number of legal matters, disputes and resultsproceedings (legal matters), some of operation.
which involve on-going litigation. These include, without limitation, legal matters involving environmental clean-up and remediation, warranty and non-warranty product liability claims, regulatory issues, contractual and personal injury claims and other legal matters. In addition, an increasesome cases, all or a portion of any loss we experience in transportation rates or fuel surcharges could materially adversely affect our sales and profitability.connection with any such legal matters will be covered by insurance; in other cases, any such losses will not be covered.

The outcome, costs and other effects of current legal matters in which we are involved, and any related insurance recoveries, cannot be determined with certainty. Although the disclosures in Note 15: Legal Proceedings, Commitments and Contingencies and Note 20: Income Taxes in the Notes to Consolidated Financial Statements contain managements current views of the effect such legal matters could have on our financial results, there can be no assurance that the outcome of such legal matters will be as currently expected. It is possible that there could be adverse judgments against us in some or all major litigation matters against us, and that we could be required to take a charge and make cash payments for all or a portion of any related awards of damages. Any one or more of such charges or cash payment could materially and adversely affect our results of operations or cash flows for the quarter or year in which we record or pay it.

REIT STATUS AND TAX IMPLICATIONS
If we fail to remain qualified as a REIT, our taxable income would be subject to tax at corporate rates and we would not be able to deduct dividends to shareholders.
In any taxable year in which we fail to qualify as a REIT, unless we are entitled to relief under the Internal Revenue Code:
We would not be allowed to deduct dividends to shareholders in computing our taxable income.
We would be subject to federal and state income tax on our taxable income at applicable corporate rates.
We also would be disqualified from treatment as a REIT for the four taxable years following the year during which we lost qualification.
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.
Certain of our business activities are subject to corporate-level income tax and potentially subject to prohibited transactions tax.
Under the Internal Revenue Code, REITs generally must engage in the ownership and management of income producing real estate. For the Company,
company, this generally includes owning and managing a timberland portfolio for the production and sale of standing timber. Accordingly, the harvesting and sale of logs, the development or sale of certain timberlands and other real estate, the manufacture and sale of wood products and the manufacture and sale of pulpwood products are conducted through one or more of our wholly-owned taxable REIT subsidiaries (TRSs), the net income of which is subject to corporate-level tax, because such activities could generate non-qualifying REIT income and thus could constitute prohibited“prohibited transactions. Prohibited transactions are defined by the Internal Revenue Code generally 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 notCode. However, if the IRS were to successfully assert that these or any of our activities conducted at the REIT constituted prohibited transactions, we could be subject to the 100 percent tax that could be imposed if a REIT were to conduct a prohibited transaction. Theon the net income of our TRSs is subject to corporate-level income tax.from such activities.
The extent of our use of our TRSTRSs may affect the price of our common shares relative to the share price of other REITs.
We conduct a significant portion of our business activities through one or more TRSs. OurThe use of our TRSs enables us to engage in non-REIT qualifying business activities such as the sale of logs, production and sale of wood products, and pulp products,the development and sale of HBUcertain higher and better use (HBU) property. Our TRSs are subject to corporate-level tax. Therefore, we pay income taxes on the income generated by our TRSs.tax. Under the Code, no more than 2520 percent (20 percent after December 31, 2017) of the value of the gross assets of a REIT may be represented by securities of one or more TRS.TRSs. This limitation may affect our ability to increase the size of our TRSsTRSs’ operations. Furthermore, our use of TRSs may cause the market to value our common shares differently than the shares of other REITs, which may not use TRSs as extensively as we use them.
We may be limited in our ability to fund distributions using cash generated through our taxable REIT subsidiaries.TRSs.
The ability of the REIT to receive dividends from our TRSTRSs is limited by the rules with which we must comply to maintain our status as a REIT. In particular, at least 75 percent of gross income for each taxable year as a REIT must be derived from passive real estate sources including sales of our standing timber and other types of qualifying real estate income and no more than 25 percent of our gross income may consist of dividends from our TRSTRSs and other non-real estate income.
This limitation on our ability to receive dividends from our TRSs may affect our ability to fund cash distributions to our shareholders using cash flows from our TRSs. The net income of our TRSs is not required to be distributed, and TRS income that is not distributed to the REIT will not be subject to the REIT income distribution requirement.
Our cash dividends are not guaranteed and may fluctuate.fluctuate.
Generally, REITs are required to distribute 90 percent of their ordinary taxable income and 95 percent of their net capital gains income. Capital gains may be retained by the REIT but would be subject to corporate income taxes. If capital gains are retained rather than distributed, our shareholders would be notified, and they would be deemed to have received a taxable distribution, with a refundable credit for any federal income tax paid by the REIT. Accordingly, we believe that we are not required to distribute material amounts of cash since substantially all of our taxable income is treated as capital gains income. Our board of directors, in its sole discretion, determines the amount of quarterly dividends to be provided to our shareholders based on consideration of a number of factors. These factors include, but are 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.
Changes in tax laws or their interpretation could adversely affect our shareholders and our results of operations.
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 tax laws could adversely affect our shareholders or increase our effective tax rates. We cannot predict with certainty whether, when, in what forms, or with what effective dates, the tax laws applicable to us or our shareholders may be changed.

LEGAL PROCEEDINGS
We are a party to a number of legal proceedings, and adverse judgments in certain legal proceedings could have a material adverse effect on our financial condition.
The costs and other effects of pending litigation against us and related insurance recoveries cannot be determined with certainty. Although the disclosure in Note 15: Legal Proceedings, Commitments and Contingencies of Notes to Consolidated Financial Statements contains managements current views of the effect such litigation will have on our financial results, there can be no assurance that the outcome of such proceedings will be as expected.
It is possible that there could be adverse judgments against us in some or all major litigation against us and that we could be required to take a charge and make cash payments for all or a portion of any damage award. Any such charge or cash payment could materially and adversely affect our results of operations or cash flows for the quarter or year in which we record or pay it.

IMPORT/EXPORT TAXES AND DUTIES
We may be required to pay significant taxes or tariffs on our exported products or countervailing and anti-dumping duties or tariffs on our imported products.
We export logs and finished wood products to foreign markets, and our ability to do so profitably is affected by U.S. and foreign trade policy. International trade disputes occur frequently and can be taken to an International Trade Court for resolution of unfair trade practices between countries. As an example, there have been many disputes and subsequent
U.S. international trade agreements regarding salespolicy could result in one or more of softwood lumber between Canada and the United States. The Softwood Lumber Agreement (SLA) between Canada and the U.S., originally signed in October 2006, expired in October 2015. A new agreement has not been reached. The SLA required Canadian softwood lumber facilities, including our mills,foreign export market jurisdictions adopting responsive trade policy making it more difficult or costly for us to pay an export tax when the price of lumber is at or below a threshold price, which could be as high as 22.5 percent if a province exceeds its total allotted export share, as well as potentially impose additional countervailing antidumping duties.our products to those countries. We could therefore experience reduced revenues and margins in any businessof our businesses that is subject to suchadversely affected by international trade tariffs, duties, taxes, customs or to the terms of the settlements of such international disputes.dispute settlement terms. To the extent such tariffstrade policies increase prices, they could also reduce the demand for our products. These tariffs or settlement termsproducts and could have a material adverse effect on our business, financial results and financial condition, including facility closures or impairments of assets. We cannot predict whetherfuture trade policy or when there will be a further extensionthe terms of the SLA or a new agreement or, if any extension or new agreement is completed, its impactsettlements of international trade disputes and their effect on our business.

DISTRIBUTION OF WRECO SHARESOUR MERGER WITH PLUM CREEK TIMBER COMPANY, INC.
We could incur substantial U.S. federal tax liability if the WRECO transaction were found not to qualify as a tax-free “reorganization” or the distribution of WRECO shares to Weyerhaeuser shareholders were found not to qualify as a tax-free distribution.
In 2014 we closed the divestiture ofin connection with our home building business, Weyerhaeuser Real Estate Company (WRECO), via a "Reverse Morris Trust" transaction pursuant to which a wholly-owned subsidiary of TRI Pointe Homes, Inc. (TRI Pointe) mergedmerger with and into WRECO, with WRECO surviving the merger and becoming a wholly-owned subsidiary of TRI Pointe. The Reverse Morris Trust transaction was structured to qualify as a tax-free reorganization and the associated distribution of WRECO shares to Weyerhaeuser shareholders as a tax-free distribution. If the transaction were determined not to qualify as a tax-free reorganization, or if the distribution does not qualify as a tax-free distribution, then Weyerhaeuser or its subsidiaries or Weyerhaeuser shareholders may be required to pay substantial U.S. federal income taxes.
If the transaction were determined not to qualify as a tax-free reorganization or the distribution not to qualify as a tax-free distribution, or if Weyerhaeuser were required to indemnify TRI Pointe and WRECO, such taxes and indemnification obligations could be substantial and could materially and adversely affect the company’s liquidity, financial condition and results of operations.
OUR MERGER WITH PLUM CREEK TIMBER COMPANY, INC.
The merger may not be completed on the terms currently contemplated, or at all.Plum Creek.
On November 6, 2015 Weyerhaeuser Company andFebruary 19, 2016, Plum Creek Timber Company, Inc. (“Plum Creek”) entered into an Agreement and Plan of Merger (“Merger Agreement”) pursuant to which Plum Creek will mergemerged with and into Weyerhaeuser Company, with Weyerhaeuser continuing as the surviving corporation. If the merger is not completed, our businesses may be adversely affected and we may be subject to various risks without realizing any of the benefits of having the merger completed, including the following:
We may be required, under certain circumstances, to pay a termination fee of $250 million.
We may be required to reimburse Plum Creek for all reasonable documented out-of-pocket fees and expenses incurred in connection with the Merger Agreement and the merger up to a maximum of $40 million.
We may experience negative reactions from the financial markets or from our customers, suppliers or employees.
We may be subject to litigation related to failure to complete the merger or to enforcement proceedings to perform our obligations under the Merger Agreement.
A delay in completing the merger, which is subject to a number of conditions, some of which are outside our control, may reduce or eliminate the expected benefits from the merger.
The merger is subject to a number of conditions, some of which are beyond our control, that could prevent, delay or otherwise materially adversely affect its completion. We cannot predict whether and when the conditions will be satisfied. In addition, several putative class action lawsuits relating to the mergercompany. Both companies have been filed and additional lawsuits may be filed, which could delay completion of the merger. We intend to vigorously defend the litigation but we cannot predict the outcome. The requirement to obtain certain regulatory approvals could delay the completion of the merger for a significant period of time or prevent it from occurring. A delay in completing the merger could cause the combined company not to realize some or all of the synergies and other benefits that it expects to achieve if the merger is successfully completed within its expected time frame. The Merger Agreement contains certain restrictions on the conduct of our business. If the merger is delayed, these restrictions could adversely affect our ability to execute business strategies or pursue attractive business opportunities. In addition, a delay could cause management to focus on completion of the merger instead of on other opportunities that could be beneficial to the company.

WEYERHAEUSER COMPANY > 2015 ANNUAL REPORT AND FORM 10-K29



The merger will involve substantial costs, and the combined company may be unable to successfully integrate the businesses of the two companies and realize the anticipated benefits of the merger.
We have incurred and expect to continue to incur substantial costs and expenses relating directly to the merger, including fees and expenses payable to financial and other professional advisors, SEC filing fees, printing and mailing costs and other transaction-related costs, fees and expenses. We expect to incur substantial expenses in connection with the integration of the businesses, policies, procedures, operations, employees, technologies and systems of Plum Creek with those of Weyerhaeuser. There are a large number of systems that must be integrated, including management information, purchasing, accounting and finance, sales, billing, payroll and benefits, fixed asset and lease administration systems and regulatory compliance. Expenses related to this integration are by their nature difficult to estimate accurately. These expenses could, particularly in the near term, exceed the savings that we expect to achieve from the realization of economies of scale and cost savings and synergies related to the integration of the businesses. These integration expenses likely will result in significant charges against earnings following the completion of the merger, but the amount and timing of such charges are uncertain.
The merger involves the combination of two independently operated public companies. The merger will require management to devote significant attention and resources to integrating business practices and operations. The combined company may fail to realize some or all of the anticipated benefits of the merger if the integration process takes longer than expected or is more costly than expected.
Uncertainties associated with the merger may adversely affect our business and operations.
Uncertainties associated with the merger could cause customers, suppliers or other entities with whom we have a business relationship to delay or defer decisions, which could negatively impact our revenues, earnings and cash flows. In addition, customers or suppliers may elect to cease doing business with us or the combined company in anticipation of or following the merger, or seek to take advantage of potential uncertainty or disruption resulting from the merger to interfere with relationships with customers, suppliers or employees.
We are dependent on the valuable experience and industry knowledge of our officers and other employees to execute our business plans and successfully conduct operations. Our success after the merger will depend in part upon our ability to retain key personnel. Current and prospective employees may feel uncertain about their roles following the merger, which may materially adversely affect our ability to attract and retain key personnel.
The market price of our common stock may decline in the future as a result of the merger.
The market price of our common stock may decline in the future as a result of the merger for a number of reasons, including our inability to successfully integrate the two companies or our failure to achieve the perceived benefits of the merger, including financial results, as rapidly as or to the extent anticipated by financial or industry analysts. Failure to successfully integrate the two companies could negatively impact our revenues, earnings and cash flows, and could materially adversely affect our ability to pay dividends at historical levels, or at all.
The combined company may incur adverse tax consequences if either Weyerhaeuser or Plum Creek has failed or fails to qualify as a REIT for U.S. federal income tax purposes.
Each of Weyerhaeuser and Plum Creek has operated in a manner that it believes has allowed itintended to qualify them as a REIT“REITs” for U.S. federal income tax purposes under the Internal Revenue Code. See “REIT Status and Tax Implications” above for a description of the REIT requirements and consequences of failingour failure to maintain REIT status. We intend to operateHowever, even if we have operated in a manner that allows us to continue to qualify as a REIT after the merger. However, even if we have operated so as to retain our REIT status, if Plum Creek were deemed to losehave lost its REIT status for a taxable year before the merger or that includesthe taxable year in which the merger occurred, we willcould face serious tax consequences that could substantially reduce cash available for distribution to our shareholders and significantly impair our ability to expand our business and raise capital. IfIn addition, if the merger were determined not to qualify as a tax-free merger, we could incur substantial federal tax liability that could materially and adversely affect the company's liquidity,cash flows, financial condition and results of operations.
TIMBERLAND SPECIFIC RISKS
Our ability to harvest and deliver timber may be subject to limitations which could adversely affect our results of operations.
Our primary assets are our timberlands. Weather conditions, timber growth cycles, access limitations, and availability of contract loggers and haulers, may restrict our ability to harvest our timberlands. Other factors that may restrict our timber harvest include damage to our standing timber by fire or by insect infestation, disease, prolonged drought, flooding, severe weather and other natural disasters. Changes in global climate conditions could intensify one or more of these factors. Although damage from such causes usually is localized and affects only a limited percentage of standing timber, there can be no assurance that any damage affecting our timberlands will in fact be limited. As is common in the forest products industry, we do not maintain insurance coverage for damage to our timberlands. Our revenues, net income and cash flow from operations are dependent to a significant extent on the pricing of our products and our continued ability to harvest timber at adequate levels. Therefore, if we were to be restricted from harvesting on a significant portion of our timberlands for a prolonged period of time, or if material damage to a significant portion of our standing timber were to occur, we could suffer a materially adverse impact to our results of operations.
On a short-term basis, we may adjust our timber harvest levels in response to market conditions. Longer term, our timber harvest levels may be affected by acquisitions of additional timberlands, sales of existing timberlands and shifts in harvest from one region to another. In addition to timberland acquisitions and sales, future timber harvest levels may be affected by changes in estimates of long-term sustainable yield because of silvicultural advances, natural disasters, fires, pests, insects and other hazards, regulatory constraints and other factors beyond our control.
Timber harvest activities are also subject to a number of federal, state and local regulations pertaining to the protection of fish, wildlife, water and other resources. Regulations, re-interpretations and litigation can restrict timber harvest activities and increase costs. Examples are federal and state laws protecting threatened, endangered and “at-risk” species, harvesting and forestry road building activities that may be restricted under the U.S. Federal Clean Water Act, state forestry practices laws, laws protecting aboriginal rights, and other similar regulations.
Our estimates of timber inventories and growth rates may be inaccurate, include risks inherent to such estimates, and may impair our ability to realize expected revenues.
We rely upon estimates of merchantable timber inventories, which include judgments regarding inventories that may be lawfully and economically harvested, timber growth rates and end-product yields when acquiring and managing working forests. These estimates, which are inherently inexact and uncertain in nature, are central to forecasting our anticipated timber harvests, revenues and expected cash flows. Timber

WEYERHAEUSER COMPANY > 2015 ANNUAL REPORT AND FORM 10-K30



growth rates and yield estimates are developed by forest biometricians and other experts using statistical measurements of a sample of trees on a given property. Timber growth equations are used that predict the rate of height and diameter growth of trees so that foresters can estimate the volume of timber that may be present in the tree stand at a given age. Tree growth varies by soil type, geographic area, and climate. Inappropriate application of growth equations in forest management planning may lead to inaccurate estimates of future volumes. If these estimates are inaccurate, our ability to manage our timberlands in a sustainable or profitable manner may be diminished, which may cause our results of operations and our stock price to be adversely affected.
OTHER RISKS

Our operating results and cash flows will be materially affected by supply and demand for timber.
A variety of factors affect prices for timber, including available supply, changes in economic conditions that impact demand, the level of domestic new construction and remodeling activity, interest rates, credit availability, population growth, weather conditions and pest infestation, and other factors. These factors vary by region, timber type (sawlogs or pulpwood logs) and species.
Timber prices are affected by changes in demand on a local, national or international level. The closure of a mill in the regions where we own timber can have a material adverse effect on demand, and therefore pricing. As the demand for paper continues to decline, closures of pulp mills have adversely affected the demand for pulpwood and wood chips in certain regions in which we operate. We export logs to Asia. While demand for Asia has remained steady, recently Asian markets have experienced a high degree of volatility, especially in China. A decrease in demand of logs from Asia may have a negative impact on log and lumber in the markets in which we compete.
Timber prices are affected by changes in timber availability at the local, national and international level. Our timberland ownership is concentrated in Alabama, Arkansas, Louisiana, Mississippi, North Carolina, Oklahoma, Oregon and Washington. In some of these states, much of the timberland is privately owned. Increases in timber prices often result in substantial increases in harvesting on private timberlands, including lands not previously made available for commercial timber operations, causing a short-term increase in supply that moderates price increases. In western states such as Oregon, and Washington, where a greater proportion of timberland is government owned, any substantial increase in timber harvesting from government-owned land could significantly reduce timber prices. On a local level, timber supplies can fluctuate depending upon factors such as changes in weather conditions and harvest strategies of local timberland owners, as well as occasionally high timber salvage efforts due to events such as unusual pest infestations or fires.

Timberlands make up a significant portion of our business portfolio.
Our real estate holdings are primarily timberlands and we may make additional timberlands acquisitions in the future. As the owner and manager of approximately 6.9 million acres of timberlands, we are subject to the risks that are inherent in concentrated real estate investments. A downturn in the real estate industry generally, or the timber or forest products industries specifically, could reduce the value of our properties and adversely affect our results of operations. Such a downturn could also adversely affect our customers and reduce the demand for our products. The risks we face may be more pronounced than if we diversified our investments outside real estate or outside timberlands.

CYBERSECURITY RISKS
We rely on information technology to support our operations and reporting environments. A security failure of that technology could impactaffect our ability to operate our businesses effectively, adversely affect our reported financial results, impactaffect our reputation and expose us to potential liability or litigation.
We use information systems to carry out our operational activities, and maintain our business records.records, collect and store sensitive data, including intellectual property, other proprietary and personally identifiable information. Some systems are internally managed and some are maintained by third-party service providers. We and our service providers employ what we believe are reasonably adequate security measures. Our ability to conduct businessmeasures, but notwithstanding these efforts, our systems could be materially and adversely affected if these systems or resources are compromised damaged or fail. This could beas a result of a cyber incident, natural disaster, hardware or software corruption, failure or error, telecommunications system failure, service provider error or failure, intentional or unintentional personnel actions or other disruption.
In the ordinary course of If by any cause our business, we collect and store sensitivesystems or information resources were compromised, or if our data including intellectual property, other proprietary information and personally identifiable information. If this data is compromised,were destroyed, misappropriated or inappropriately disclosed, itour business operations could have a material adverse effect, includingbe negatively affected. Additionally, we could suffer significant loss or incur significant liability, including: damage to our reputation,reputation; loss of customers,customer confidence or goodwill; and significant expensesexpenditures of time and money to address and resolve the issues,remediate resulting damages to affected individuals or business partners, or to defend ourselves in resulting litigation or other legal proceedings, by affected individuals, business partners and/or regulators.

RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK
PENSION PLAN LIABILITY
Investment returns on our pension assets may be lower than expected, or interest rates may decline, requiring us to make significant additional cash contributions to our benefit plans.
A portion of our current and former employees have accrued benefits under our defined benefit pension plans. Although the plans are not open to employees hired on or after January 1, 2014, current employees hired before that time continue to accrue benefits. Requirements for funding our pension plan liabilities are based on a number of actuarial assumptions, including the expected rate of return on our plan assets and the discount rate applied to our pension plan obligations. Fluctuations in equity market returns and changes in long-term interest rates could increase our costs under our plans and may significantly affect future contribution requirements.  It is unknown what the actual investment return on our pension assets will be in future years and what interest rates may be at any given point in time. We cannot therefore provide any assurance of what our actual pension plan costs will be in the future, or whether we will be required under applicable law to make future material plan contributions. See Note 10: Pension and Other Postretirement Benefit Plans in the Notes to Consolidated Financial Statements for additional information about these plans, including funding status.

STOCK-PRICESTRATEGIC INITIATIVES
Our business and financial results may be adversely affected if we are unable to successfully execute on important strategic initiatives.
There can be no assurance that we will be able to successfully implement important strategic initiatives in accordance with our expectations, which may result in an adverse effect on our business and financial results. These strategic initiatives are designed to improve our results of operations and drive long-term shareholder value, and include, among others: optimizing cash flow through operational excellence; reducing costs to achieve industry-leading cost structure; and innovating in higher-margin products.
We may be unsuccessful in carrying out our acquisition strategy.
We intend to strategically pursue acquisitions of timberland properties when market conditions warrant. As with any investment, our acquisitions may not perform in accordance with our expectations. In addition, we anticipate financing such acquisitions through cash from operations,

WEYERHAEUSER COMPANY > 2018 ANNUAL REPORT AND FORM 10-K31



borrowings under our unsecured credit facilities, proceeds from equity or debt offerings or proceeds from asset dispositions, or any combination thereof. Our inability to finance future acquisitions on favorable terms could adversely affect our results of operations.

WORKFORCE
Our business is dependent upon attracting, retaining and developing key personnel.
Our success depends, to a significant extent, upon our ability to attract, retain and develop senior management, operations management and other key personnel. Our financial condition or results of operations could be significantly adversely affected if we were to fail to recruit, retain, and develop such personnel, or if there were to occur any significant increase in the cost of providing such personnel with competitive total compensation and benefits.
Availability of Independent Contractors
We use independent third-party contract loggers and haulers to deliver our logs to our customers. As a result of the weak business conditions in the timber business that persisted for several years, there are fewer of these contractors available in certain markets to harvest and deliver logs. This shortage in logging and hauling contractors has resulted in an overall increase in logging and hauling costs and, in some cases, the general availability of these contractors. Any increase in harvest levels due to positive changes in macroeconomic conditions driving demand for logs could further strain the existing supply of logging and hauling contractors. This, in turn, could increase the cost of log supply and delivery, or prevent us from fully capitalizing on favorable market conditions by limiting our ability to access and deliver our logs to market.

STOCK PRICE VOLATILITY
The market price of our common stock may be influenced by many factors, some of which are beyond our control.
The market price of our common stock may be influenced by many factors, some of which are beyond our control, including without limitation those described above under "Risks Related to our Industries and Business" andelsewhere in this report, as well as the following:

changes in accounting principles,principles; and
changes in tax laws and regulations.

WEYERHAEUSER COMPANY > 2015 ANNUAL REPORT AND FORM 10-K31



In addition, there has been significant volatility in the market price and trading volume of securities of companies operating in the forest products industry that often has been unrelated to theindividual company operating performance of particular companies.performance.
Some companies that have hadexperienced volatile market prices for their securities have had securities litigation brought against them. If litigation of this type is brought against us, it could result in substantial costs and divert managements attention and resources.

PREFERENCE SHARES
Our common shares will rank junior to our mandatory convertible preference shares with respect to dividends and amounts payable in the event of our liquidation.
Our common shares will rank junior to our mandatory convertible preference shares with respect to the payment of dividends and amounts payable in the event of our liquidation, dissolution or winding-up. This means that, unless full cumulative dividends have been paid or set aside for payment on all outstanding mandatory convertible preference shares for all past dividend periods and the then current dividend period, no dividends may be declared or paid on our common shares. Likewise, in the event of our voluntary or involuntary liquidation, dissolution or winding-up, no distribution of our assets may be made to holders of our common shares until we have paid to holders of the mandatory convertible preference shares a liquidation preference equal to $50.00 per share plus accrued and unpaid dividends.
Certain provisions in the mandatory convertible preference shares could delay or prevent an otherwise beneficial takeover or takeover attempt of us and, therefore, the ability of holders to exercise their rights associated with a potential fundamental change.
Certain provisions in our mandatory convertible preference shares could make it more difficult or more expensive for a third party to acquire us. For example, if a fundamental change were to occur on or prior to July 1, 2016, holders of the mandatory convertible preference shares may have the right to convert their mandatory convertible preference shares, in whole or in part, at an increased conversion rate and be entitled to receive a fundamental change dividend make-whole amount equal to the present value of all remaining dividend payments on their mandatory convertible preference shares. These features of the mandatory convertible preference shares could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management.WEYERHAEUSER COMPANY > 2018 ANNUAL REPORT AND FORM 10-K32

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (MD&A)

WHAT YOU WILL FIND IN THIS MD&A
 
Our MD&A includes the following major sections:
economic and market conditions affecting our operations;
financial performance summary;
discussion of the softwood lumber agreement;
results of our operations — consolidated and by segment;
liquidity and capital resources — where we discuss our cash flows;
off-balance sheet arrangements;
environmental matters, legal proceedings and other contingencies; and
accounting matters — where we discuss critical accounting policies and areas requiring judgments and estimates.

ECONOMIC AND MARKET CONDITIONS AFFECTING OUR OPERATIONS
The demand for grade logs within our Timberlands segment is directly affected by production levels of domestic wood-based building products. The strength of the U.S. housing market strongly affects demand in our Wood Products segment, as does repair and remodeling activity. Our Timberlands segments. As publishedsegment, specifically the Western region, is also affected by the U.S. Census Bureau, total U.S.export demand and trade policy. Japanese housing starts for 2015 were 1,111,000 units, with single-family units accounting for 715,000are a key driver of the total. This represents a 10 percent increaseexport log demand in single-family starts from 2014, which were 648,000 units. Multi-family construction also increased in 2015 to 396,000 units compared with 358,000 in 2014. Expectations are for a similar increase in 2016. Consensus forecasts place expected total housing starts between 1.2 and 1.3 million units for 2016. Sources include IHS Global Insight, John Burns Real Estate and RISI. While housing has improved significantly since the recession of 2009, currentJapan. The demand for new housing continues to run below historic pre bubble averages. The 25-year period of 1976-2000 averaged 1.5 million total starts and 1.1 million single family starts, levels which have not yet been achieved in the post recession period.
Wood Products primarily sells into the new residential building and repair and remodel markets. Demand for wood products continued to improve in 2015 following the growth in home construction, however, growth in production also expanded and prices were lower in 2015 than 2014. The Random Lengths framing lumber composite was 14 percent lower in 2015 versus 2014 while oriented strand board (OSB) was 4 percent lower in 2015 as measured by Random Lengths North Central Price. Expectations are for similar to slightly higher wood product prices in 2016 as demand continues to increase with growth in housing starts and remodeling.
Demand for logspulpwood from our Timberlands segment is directly affected by the production of wood-based building productspulp, paper and OSB as well as the demand for biofuels, such as pellets made from pulpwood.
Due to the partial government shutdown that occurred through late January 2019, full-year 2018 housing data is unavailable, however, for the January 2018 through November 2018 period, housing starts were 1.18 million total units, which is 5 percent above the total of 1.12 units for the same period in 2017 according to the U.S. Census Bureau. Single family units totaled 825 thousand compared to 794 thousand in 2017, a 4 percent increase. Multifamily starts were 354 thousand units for the first 11 months of 2018, which is 8 percent higher than 2017 for the same period. We continue to expect improving U.S. housing starts and anticipate a level of approximately 1.30 million units in 2019 which would be a 3 percent gain over 2018, assuming the year to date gains continue into December. We attribute this continued improvement primarily to ongoing employment growth, strong consumer confidence and mortgage rates, which have stabilized and declined since peaking in late 2018 and remain affordable on a historic basis.
According to the Joint Center for Housing of Harvard University, the Leading Indicator of Remodeling Activity (LIRA) projects that the year-over-year increase in residential remodeling expenditures reached 7.2 percent in 2018 and is expected to average 6.5 percent in 2019, with expenditure growth tapering through the year and reaching the long term average level of 5.2 percent in the fourth quarter 2019.
In U.S. wood product markets, prices in 2018 were mixed, rising the first half of the year to post record levels in May and June, only to fall sharply in third and fourth quarter 2018, as supply issues related to transportation eased and producers increased output in response to high prices. According to Random Lengths, the framing lumber composite averaged $459/MBF in 2018, an 11 percent increase over 2017. According to Forest Economic Advisors, LLC, U.S. lumber consumption is expected to grow at a 3.5 percent rate in 2019, however, due to declines forecast in off-shore export volumes and increases in off-shore imports, the increase in overall demand on North American mills is expected to rise by 2.5 percent over 2018. Log markets in our Western holdings.the west were consistent with wood products manufacturing, exhibiting strong demand and pricing in the first half followed by slower demand and weaker market prices for western logs in the second half of 2018. In the South, Southern pine sawlogsouth, log supplies kept pace with demand, leaving prices flat throughout 2018.
Log inventories in Chinese ports decreased 0.9 percent in December 2018 compared to November 2018 as reported by International Wood Markets China Bulletin. While the decline in overall volume was slight, there was a greater decline in North American Hemlock and Douglas fir volumes. These species were flat to slightly higher in 2015 as available supplies continue to match or exceed growth in demand. Western log prices were5.9 percent lower in 2015 due primarilyDecember 2018 compared to November 2018 which has positive implications for demand at the start of 2019 as suppliers will need to re-build depleted inventories. Total North American volumes increased in 2018 by 3 percent over 2017 despite retaliatory tariffs imposed by the Chinese government against U.S. imports. In addition, exchange rates also have an effect on our export business to China. A weaker yuan relative to the pullbackU.S. dollar reduces the competitiveness of U.S. logs relative to those imported from other countries whose currencies have not appreciated in a similar manner. During 2018, the yuan weakened relative to the U.S. dollar, which affects the competitiveness of our export logs to China.
In Japan, housing starts for November year to date for 2018 were down 2.7 percent from the same period in 2017 while the key Post and Beam segment was 0.8 percent lower in the first 11 months of 2018 compared to 2017.
We expect demand from China which had been actively competing with domestic lumber producers for sawlogs. Expectations are for slightly improved log prices as off-shoreand Japan in 2019 to be similar to demand improves over 2015 and domestic wood products manufacturing output increases with rising housing starts creating increased log demand.experienced in 2018.
Cellulose FibersOur Real Estate & ENR segment is primarily affected by global supply and demand factors and the relative strengthhealth of the U.S. dollar. The slowdowneconomy and especially the U.S. housing sector of the economy. According to the Realtors Land Institute (RLI) of the National Association of Realtors, the dollar volume of rural properties sold, including timber, grew 2 percent in global growth2018, and reduced expectations for emerging economies slowed demand growth for pulpper acre prices were also up 2 percent on average. Additionally, RLI expects these trends to continue with prices and volumes of land transactions forecast to rise 3 percent in 2015. The U.S. dollar continued to strengthen versus the Euro in 2015, rising 12 percent due to stronger US economic growth and increasingly accommodative monetary policies in Eurozone economies. Consequently prices for benchmark NBSK pulp were 8% lower in 2015 versus 2014. Expectations are for similar to slightly lower prices in 2016 as global economic growth is expected to be weak, which will limit growth in demand for products made with cellulose fibers. Furthermore, the US dollar is expected to remain strong relative to other currencies including the euro and a weak euro has historically been associated with lower US dollar prices for cellulose fibers.2019.

SOFTWOOD LUMBER AGREEMENT
We operate a total of 19 softwood lumber mills with a total capacity of approximately 5 billion board feet. Three of these mills, located in Canada, produce approximately 900 million board feet annually, and sell products in Canada, Asia, and the U.S.
In April 2017, the U.S. Department of Commerce announced a preliminary determination that it would implement countervailing duties (CVD) on Canadian softwood lumber shipments to the U.S at the rate of 19.88 percent with a 90 day retroactive period. The preliminary countervailing duties were suspended in August 2017, at which time we effectively stopped accruing for the expense. The suspension of the countervailing duties was set to last until the US International Trade Commission reached its final determination of injury, which was issued in December 2017.
In June 2017, the U.S. Department of Commerce announced a preliminary determination that it would implement anti-dumping duties (AD) on Canadian softwood lumber shipments to the U.S. at the rate of 6.87 percent with a 90 day retroactive period.
Affirmative final determinations by the Department of Commerce (DOC) and the US International Trade Commission (USITC) in December 2017 issued CVD and AD duty orders on certain softwood lumber products from Canada. Based on these determinations, the CVD rate applicable to Weyerhaeuser is 14.19 percent and is assessed on entries of softwood lumber from Canada for consumption on or after April 28, 2017. The AD rate applicable to Weyerhaeuser is 6.04 percent and is assessed on entries of softwood lumber from Canada for consumption on or after June 30, 2017.
For the years ended December 31, 2018 and December 31, 2017, we have expensed CVD and AD duties at the final published rates totaling $21 million and $7 million, respectively. These costs are recorded in "Costs of sales" within the Wood Products segment.

RESULTS OF OPERATIONS
In reviewing our results of operations, it is important to understand these terms:
Sales realizations refer to net selling prices — this includes selling price plus freight minus normal sales deductions.deductions;
Net contribution to earnings refers to earnings (loss) attributable to Weyerhaeuser shareholders before interest expense and income taxes.
Our merger with Plum Creek during first quarter 2016 affected the comparability of our consolidated operating results with 2016. Our results do not include pre-merger results of Plum Creek operations from January 1, 2016 through February 19, 2016.

COMPARING 20152018 WITH 20142017
Net Sales
Net sales decreased $321increased $280 million — 4 percent — primarily due to:
lowerWood Products segment net sales to unaffiliated customers increased $281 million, primarily attributable to increased sales realizations across all product lines; and
Real Estate & ENR segment net sales to unaffiliated customers increased $26 million primarily attributable to increased acres sold.
These increases were offset by a decrease in Timberlands segment net sales to unaffiliated customers by $27 million, primarily attributable to decreased revenue resulting from the divestiture of our Uruguayan operations in third quarter 2017, partially offset by an increase in Western log sales realizations.
Costs of Sales
Costs of sales increased $294 million $147 million6 percent — primarily due to lower averageincreased log sales realizations and export sales volumesfiber costs within our Wood Products and Timberlands segments as well as an increase in acres sold coupled with higher per acre basis of real estate sold within our Real Estate and ENR segment. Refer to additional analysis of fluctuations within our Timberlands, Real Estate, Energy and Natural Resources and Wood Products discussion below.

WEYERHAEUSER COMPANY > 2018 ANNUAL REPORT AND FORM 10-K38



Operating Income
Operating income increased $263 million — 23 percent — primarily due to:
$290 million decrease in charges for product remediation; and
$147 million decrease in charges related to a noncash pretax impairment in 2017, with no similar charges in 2018. This impairment was a result of our agreement to sell our Uruguayan operations, as announced during June 2017 (refer to Note 18: Charges for Integration and Restructuring, Closures and Asset Impairments in the Notes to Consolidated Financial Statements).

These increases were partially offset by the following:
$99 million gain recorded in fourth quarter 2017 that did not occur in 2018 as a result of the sale of land in our Southern timberlands region to Twin Creeks (refer to Note 9: Related Parties in the Notes to Consolidated Financial Statementsfor further details);
$37 million decrease in environmental remediation insurance recoveries received; and
$14 million decreased consolidated gross margin, as described above.
Net Earnings Attributable to Weyerhaeuser Common Shareholders
Net earnings attributable to Weyerhaeuser common shareholders increased $166 million — 29 percent — primarily due to:
a$263 million increase to operating income, as described above;
a $75 million decrease in income tax expense; and
an $18 million decrease in interest expense, net of capitalized interest.

These increases to net earnings were partially offset by a $200 million decrease due to a noncash pretax settlement charge related to our U.S. qualified pension plan lump sum offer (refer to Note 10: Pension and Other Postretirement Benefit Plans in the West,Notes to Consolidated Financial Statements)
COMPARING 2017 WITH 2016
Net Sales
Net sales increased $831 million — 13 percent — primarily due to:
Wood Products net sales to unaffiliated customers increased $640 million primarily attributable to increased sales realizations across all product lines, as well as increased sales volumes within our oriented strand board, engineered I-joists, medium density fiberboard, and our engineered solid section product lines. Additionally, upon completion of the sales of our former Cellulose Fibers businesses, chips previously sold to Cellulose Fibers are now sales to unaffiliated customers. Refer to Note 4: Discontinued Operations and Other Divestitures in the Notes to Consolidated Financial Statementsfor further details regarding these divestitures.
Timberlands net sales to unaffiliated customers increased $137 million, which is primarily attributable to increased Southern and lowerOther (includes our Canadian operations and timberlands included in the Twin Creeks Venture) delivered log sales volumes, as well as, an increase in the South;Western log sales prices.
lower Wood Products segmentReal Estate & ENR net sales to unaffiliated customers increased $54 million attributable to an increase in timberlands acres sold in Real Estate and an increase in royalties.
Costs of Sales
Costs of sales increased $318 million $98 million6 percent — primarily due to decreased structural lumberincreased sales volumes within our Wood Products segment, as described above. Refer to additional analysis of fluctuations within our Timberlands, Real Estate, Energy and OSB average realizations,Natural Resources and Wood Products discussion below.
Operating Income
Operating income increased $309 million — 38 percent — primarily due to:
an increase to consolidated gross margin of $513 million, as described above;
an increase in other operating income, net of $75 million, which is primarily attributable to:
a $99 million gain recorded in fourth quarter 2017 as a result of the sale of land in our Southern timberlands region to Twin Creeks (refer to Note 9: Related Parties in the Notes to Consolidated Financial Statements for further details);
a $42 million benefit related to environmental remediation insurance recoveries received in 2017; and
a $44 million decrease in gains on disposition of nonstrategic assets, primarily attributable to a $36 million pretax gain recognized in the first quarter of 2016 on the sale of our Federal Way, Washington headquarters campus (refer to Note 20: Other Operating Costs (Income), Net in the Notes to Consolidated Financial Statements for further information).

These increases were partially offset by higher structural lumber, OSB, and engineered solid section sales volumes and higher salesthe following:

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 ability of buyers to obtain financing,
the number of competing properties listed for sale,
the seasonal nature of sales (particularly in the northern states),
the plans of adjacent landowners,
our expectations of future price appreciation,
the timing of harvesting activities, and
the availability of government and not-for-profit funding (especially for conservation sales).
In any period, the average sales price per acre will vary based on the location and physical characteristics of parcels sold.

COMPARING 2015 WITH 2014
Net Sales
Net sales decreased $76 million — 4 percent — primarily due to the following:
pulp average sales realizations decreased $31 per ton — 4 percent;
liquid packaging board average sales realizations decreased $48 per ton — 4 percent; and
other products sales volumes decreased 12 percent.
These decreases were partially offset by increased sales volumes for liquid packaging board of 2 percent.
Net Contribution to Earnings
Net contribution to earnings decreased $172 million — 59 percent — primarily due to:
losses from an equity affiliate — $105 million — primarily due to an $84 million noncash asset impairment recorded in the fourth quarter 2015;
lower pulp average sales realizations — $58 million;
higher operating costs primarily due to scheduled maintenance outages and the West Coast port slowdown — $46 million;
lower liquid packaging board average sales realizations — $18 million; and
higher fiber costs — $13 million.
These decreases were partially offset by:
lower energy and chemical costs — $28 million,
lower translated Canadian operating costs due to the strengthening of the U.S. dollar — $27 million and
lower selling, general and administrative expenses — $10 million.
COMPARING 2014 WITH 2013
Net Sales
Net sales increased $34 million — 2 percent — primarily due to increased sales realizations for pulp of $50 per ton — 6 percent and liquid packaging board of $61 per ton — 6 percent.

This was partially offset by decreased sales volumes for pulp of 2 percent and liquid packaging board of 10 percent.
Net Contribution to Earnings
Net contribution to earnings increased $91 million — 46 percent — primarily due to:
higher pulp and liquid packaging board sales realizations — $108 million and
lower translated Canadian operating costs due to the strengthening of the U.S. dollar — $14 million.

Unallocated Items in 2015 include:
$13a $75 million noncash impairment charge recognizedincrease in first quarter 2015other products produced, primarily attributable to increased chip sales. Chips were previously sold to our former Cellulose Fibers segment and were therefore considered intersegment sales until the sale of our Cellulose Fibers businesses which occurred in the second half of 2016. Upon completion of these divestitures, chips sold to those businesses were considered sales to unaffiliated customers. (Refer to Note 4: Discontinued Operations and Other Divestitures in the Notes to Consolidated Financial Statements for further details regarding these divestitures.);
a $50 million increase in engineered solid section, primarily attributable to an 8 percent increase in sales volumes as well as a 3 percent increase in average sales realizations; and
a $46 million increase in engineered I-joists, primarily attributable to a 13 percent increase in sales volume as well as a 3 percent increase in average sales realizations.
Costs of Sales
Costs of sales increased $192 million — 5 percent — primarily attributable to an overall increase in sales volumes, as discussed above. This increase was offset by the mix of products sold during 2017 compared to 2016.
Operating Income and Net Contribution to Earnings
Operating income and net contribution to earnings increased $57 million — 11 percent — primarily due to increased gross margin, as discussed above. This was partially offset by:
the $290 million addition of charges (recoveries) for product remediation, net in 2017, as there were no similar charges during 2016 (refer to Note 19: Charges (Recoveries) for Product Remediation, Net in the Notes to Consolidated Financial Statements for further information).
a $68 million decrease in intersegment sales in 2017 compared to 2016, which is primarily attributable to decreased intersegment chip sales. Prior to our divestitures of our former Cellulose Fibers business, which occurred in the second half of 2016, chips sold to these businesses were considered intersegment sales. Upon completion of these divestitures, chips sold to our former Cellulose Fibers businesses were considered sales to unaffiliated customers.
a $7 million increase in other operating costs, net, related to countervailing and anti-dumping duties. Refer to Softwood Lumber Agreement for further information regarding these regulations.

We are required to pay corporate income taxes on earnings of our TRSs, which includes our Wood Products segment and portions of our Timberlands and Real Estate & ENR segments' earnings. Our provision for income taxes is primarily driven by earnings generated by our TRSs. Overall performance results for our business segments can be found in Results of Operations/Timberlands, Results of Operations/Real Estate, Energy and Natural Resources, and Results of Operations/Wood Products.
On December 22, 2017, H.R. 1, commonly known as the Tax Cuts and Jobs Act (Tax Act), was enacted. The Tax Act contains significant changes to corporate taxation, including the reduction of the corporate tax rate from 35 percent to 21 percent, increased deductions for capital spending and limitations on interest expense deductions. The Tax Act does not affect our REIT status or the provisions that allow us to pay capital gain dividends to our shareholders.
As a result of the reduction in the corporate tax rate, we revalued our deferred tax assets and liabilities and recorded a tax expense of $74 million during 2017, which reduced our net deferred tax asset.
Our provision (benefit) for income taxes for our continuing operations over the last three years was:
$(3)59 million in 20152018,
$185134 million in 20142017 and
$(171)89 million in 20132016.
During 2015, our provision for income taxes decreased $188 million as compared with 2014, primarily due to lower earnings in our TRS in 2015.  We also2018, we recorded a $13$41 million tax benefit for the expiration of the company’s built-in-gainsrelated to contributions made to our pension plan and deducted on our 2017 U.S. federal tax period duereturn and a $21 million tax charge related to a change in tax law in the fourth quarter 2015, and a $28 million tax benefit for the reduction in the deferred tax liability associated with an equity affiliate resulting from a non-cash impairment charge recorded by that entity. settlement charge.

See alsoNote 21: Income Taxes in Notes to Consolidated Financial Statements, which outlines the major components related to our income tax provision.

As a REIT, we generally are not subject to corporate level tax on income of the REIT that is distributed to shareholders. We are no longer subject to corporate taxes on built-in-gains (the excess of fair market value over tax basis at January 1, 2010) due to a change in tax law in the fourth quarter 2015, which statutorily shortened the built-in-gains tax period from 10 years to 5 years following the REIT conversion. We continue to be required to pay federal corporate income taxes on earnings of our TRS, which includes our manufacturing businesses and the portion of our timberlands segment income included in the TRS.

ACCOUNTING MATTERS

CRITICAL ACCOUNTING POLICIES
OurIn the preparation of our financial statements we follow established accounting policies and make estimates that affect both the amounts and timing of the recording of assets, liabilities, revenues and expenses. Some of these estimates require judgments about matters that are inherently uncertain. Accounting policies whose application may have a significant effect on the reported results of operations and financial position are considered critical accounting policies involve a higher degree of judgment and estimates. They also have a high degree of complexity.policies.
In accounting, we base our judgments and estimates on:
historical experience and
assumptions we believe are appropriate and reasonable under current circumstances.
Actual results, however, may differ from the estimated amounts we have recorded.
Our most critical accounting policies relate to our:
pension and postretirement benefit plans;
potential impairments of long-lived assets; and
legal, environmental and product liability reserves.

PENSION AND POSTRETIREMENT BENEFIT PLANS
We sponsor several pension and postretirement benefit plans for our employees. Key assumptionsestimates we use in accounting for the plans include our:
fair value of our plan assets,
expected long-term rate of return on plan assets and
discount rates,
anticipated trends in health care costs,
assumed increases in salaries and
mortality rates.
At the end of every year, we review our assumptionskey estimates with external advisers and make adjustments as appropriate. We use these estimates to calculate plan asset and liability information as of year-end as well as pension and postretirement expense for the following year. Actual experience that differs from our assumptionsestimates or any changes in our assumptionsestimates could have a significant effect on our financial position, results of operations and cash flows.
Other factors that affect our accounting for the plans include:
actual pension fund performance,
levelFair Value of lump sum distributions,
plan changes and amendments,
changes in plan participation or coverage and
portfolio changes and restructuring.
This section provides more information about our:
expected long-term rate of return and
discount rates.
Expected Long-Term Rate of Return on Plan Assets
Plan assets are assets of the pension plan trusts that fund the benefits provided under the pension plans. The fair value of our plan assets estimates the amount that would be received if we were to sell each asset in an orderly transaction between market participants at the reporting date. We estimate the fair value of these assets based on the information available during the year-end reporting process. In some cases, primarily private equity and hedge funds, the available information consists of net asset values as of an interim date, adjusted for known events occurring between the interim date and year-end.
We value the pension plan assets based on the observability of exit pricing inputs and classify pension plan assets based on the lowest level input that is significant to the fair value measurement of the pension plan assets in their entirety. These inputs are classified within the fair value hierarchy as follows:
Level 1: Inputs are unadjusted quoted prices for identical assets or liabilities traded in an active market.
Level 2: Inputs are quoted prices in non-active markets for which pricing inputs are observable either directly or indirectly at the reporting date.
Level 3: Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.
Assets that are measured at fair value using the net asset value per share as a practical expedient are not categorized within the fair value hierarchy.
In general, we value our pension plan assets, as follows:
cash and short-term investments are valued at cost, which approximates market;
fixed income investments are valued at exit prices quoted in the public market;
hedge funds, private equity funds and related fund units are valued based on the net asset value of the funds; and
derivative instruments are valued based upon valuation statements received from each derivative’s counterparty.

Assets that do not have readily available quoted prices in an active market require more judgment to value and have increased risk.
Expected Long-Term Rate of Return on Plan Assets
The expected long-term rate of return is our estimate of the long-term rate of return that our plan assets will earn. Our expected long-term rate of return is important in determining the net periodic benefit or cost we recognize for our plans.
Over the 30 years it has been in place, our U.S. pension trust investment strategy has achieved a 14.2 percent net compound annual return rate.
After considering available information at the end of 2015,2016, we continuedetermined that it was appropriate to assume an expectedreduce our assumption of long-term rate of return on plan assets from 9.0 percent for the year ended December 31, 2016, to 8.0 percent for the year ended December 31, 2017. This decision was based on a variety of 9.0 percent. Factors we considered include:
factors, including the net compounded annual return of 8.0 percent achieved by our U.S. pension trust investment strategy the past 5 years and
current and expected valuation levels in the global equity and credit markets. We continued to use an assumption of 8.0 percent for the year ended December 31, 2018.

As of the end of 2018, we have begun implementing a change in our asset strategy to an allocation that will more closely match the plan’s liability profile moving forward, resulting in a larger allocation of our assets into fixed income securities. With this change, we have determined that we will further reduce our assumption of long-term rate of return on plan assets to 7.0 percent for the year ended December 31, 2019.
Factors we considered include:
historical returns for a portfolio of assets similar to our expected allocation and
expected future performance of similar asset classes.
Our expected long-term rate of return is important in determining the net periodic benefit or cost we recognize for our plans. Every 0.5 percent50 basis point decrease in our expected long-term rate of return would increase expense or reduce a credit by approximately:
$2414 million for our U.S. qualified pension plans and
$4 million for our Canadian registered pension plans.
The actual return on plan assets in any given year may vary from our expected long-term rate of return. Actual returns on plan assets affect the funded status of the plans. Differences between actual returns on plan assets and the expected long-term rate of return are reflected as adjustments to cumulativeaccumulated other comprehensive income (loss),loss, a component of total equity.
Discount Rates
The discount rate is used to estimate the net present value of our plan obligations. Our discount rates as of December 31, 20152018, are:
4.54.4 percent for our U.S. pension plans — compared with 4.13.7 percent at December 31, 2014;
2017;
4.04.2 percent for our U.S. postretirement plans — compared with 3.63.5 percent at December 31, 2014;
2017;
4.03.7 percent for our Canadian pension plans — compared with 3.93.5 percent at December 31, 2014;2017; and
3.93.7 percent for our Canadian postretirement plans — compared with 3.83.4 percent at December 31, 20142017.

WEYERHAEUSER COMPANY > .2018 ANNUAL REPORT AND FORM 10-K51


We review our discount rates annually and revise them as needed.
The discount rates are selected at the measurement date by matching current spot rates of high-quality corporate bonds with maturities similar to the timing of expected cash outflows for benefits.
Pension and postretirement benefit expenses for 20162019 will be based on the 4.54.4 percent and 4.04.2 percent assumed discount rates for U.S. plans, respectively, and 43.7 percent and 3.9 percent assumed discount rates for the Canadian plans.
Our discount rates are important in determining the cost of our plans. A 0.5 percent50 basis point decrease in our discount rate would increase expense or reduce a credit by approximately:
$3515 million for our U.S. qualified pension plans and
$5 million for our Canadian registered pension plans.

CONTINGENT LIABILITIES
We are subject to lawsuits, investigations and other claims related to environmental, product and other matters, and are required to assess the likelihood of any adverse judgments or outcomes to these matters, as well as potential ranges of probable losses.
We record contingent liabilities when:
it becomes probable that we will have to make payments and
the amount of loss can be reasonably estimated.
Assessing probability of loss and estimating probable losses requires analysis of multiple factors, including:
historical experience,
evaluations of relevant legal and environmental regulations,

In addition to contingent liabilities recorded for probable losses, we disclose contingent liabilities when there is a reasonable possibility that an ultimate loss may occur.
While we do our best in developing our projections, recorded contingent liabilities are based on the best information available and actual losses in any future period are inherently uncertain. If estimated probable future losses or actual losses exceed our recorded liability for such claims, we would record additional charges in other (income) expense, net.charges. These exposures and proceedings can be significant and the ultimate negative outcomes could be material to our operating results or cash flow in any given quarter or year. See Note 15: Legal Proceedings, Commitments and Contingencies in the Notes to Consolidated Financial Statements for more information.

PERFORMANCE MEASURES

We use Adjusted Earnings before Interest, Taxes, Depreciation, Depletion and Amortization (Adjusted EBITDA) as a key performance measure to evaluate the performance of the consolidated company and our business segments. This measure should not be considered in isolation from and is not intended to represent an alternative to our results reported in accordance with U.S. generally accepted accounting principles (U.S. GAAP). However, we believe Adjusted EBITDA provides meaningful supplemental information for our investors about our operating performance, better facilitates period to period comparisons, and is widely used by analysts, lenders, rating agencies and other interested parties.Ourparties. Our definition of Adjusted EBITDA may be different from similarly titled measures reported by other companies. Adjusted EBITDA, as we define it, is operating income from continuing operations adjusted for depreciation, depletion, amortization, basis of real estate sold, pension and postretirement costs not allocated to business segments (primarily interest cost, expected return on plan assets, amortization of actuarial loss and amortization of prior service cost/credit), and special items and discontinued operations.items. Adjusted EBITDA excludes results from joint ventures.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Our significant accounting policies describe:
our election to be taxed as a real estate investment trust,
how we report our results,
changes in how we report our results and
how we account for various items.
OUR ELECTION TO BE TAXED AS A REAL ESTATE INVESTMENT TRUST (REIT)
Starting with our 2010 fiscal year, we elected to be taxed as a REIT. REIT income can be distributed to shareholders without first paying corporate level tax, substantially eliminating the double taxation on income. We expect to derive most of our REIT income from investments in timberlands, including the sale of standing timber through pay-as-cut sales contracts.contracts and lump sum timber deeds.
We were no longer subject to the REIT income can be distributedbuilt-in gains tax as of December 31, 2014. Our built-in gains tax period expired in 2015 due to shareholders without first paying corporate levela change in U.S. tax substantially eliminatinglaw that statutorily shortened the double taxation on income. A significant portion of our timberland segment earnings receives this favorablebuilt-in gains tax treatment. Weperiod to 5 years from 10 years. This means we are no longer subject to federal corporate level income taxes on built-in-gains (the excesssales of REIT property that had a fair market value overin excess of tax basis atwhen we converted to a REIT on January 1, 2010) due to a change in tax law in the fourth quarter 2015, which statutorily shortened the built-in-gains tax period from 10 years to 5 years following the REIT conversion.2010. We continue to be required to pay federal corporate income taxes on earnings of our Taxable REIT Subsidiary (TRS), which includes our manufacturing businessesWood Products segment and the portionportions of our Timberlands segment income included in the TRS.and Real Estate, Energy and Natural Resources (Real Estate & ENR) segments.
HOW WE REPORT OUR RESULTS
Our report includes:
consolidated financial statements,
our business segments,
foreign currency translation,
estimates, and
fair value measurements.measurements and
CONSOLIDATED FINANCIAL STATEMENTSforeign currency translation.
Consolidated Financial Statements
Our consolidated financial statements provide an overall view of our results and financial condition. They include our accounts and the accounts of entities that we control, including:
majority-owned domestic and foreign subsidiaries and
variable interest entities in which we are the primary beneficiary.
They do not include our intercompany transactions and accounts, which are eliminated, and noncontrolling interests are presented as a separate component of equity.
We account for investments in and advances to unconsolidated equity affiliates using the equity method. We record our share of equity in net earnings of equity affiliates within "Earnings (loss) from equity affiliates" in our Consolidated Statement of Operationsin the period in which the earnings are recorded by our equity affiliates.eliminated.
Throughout these Notes to Consolidated Financial Statements, unless specified otherwise, references to “Weyerhaeuser,” "the company," “we” and “our” refer to the consolidated company.
OUR BUSINESS SEGMENTSOur Business Segments
Reportable business segments are determined based on the company’s "management approach," as defined by Financial Accounting Standards Board (FASB) ASC 280, “Segment Reporting.” The management approach is based on the way the chief operating decision maker organizes the segments within a company for making decisions about resources to be allocated and assessing their performance.
We are principally engaged in:
growing and harvesting timber; and
manufacturing, distributing and selling products made from trees.trees;
maximizing the value of every acre we own through the sale of higher and better use (HBU) properties; and
monetizing reserves of minerals, oil, gas, coal, and other natural resources on our timberlands.
Our business segments are organized based primarily on products and services.
Our Business Segments and Products
SEGMENTPRODUCTS AND SERVICES
TimberlandsLogs, timber and leased recreational access
Real Estate & ENRSales of timberlands, rights to explore for and extract hard minerals, construction materials, oil and gas production, wind, solar and international wood productscoal
Wood ProductsSoftwood lumber, engineered wood products, structural panels, medium density fiberboard and building materials distribution
Cellulose FibersPulp, liquid packaging board and an equity interest in a newsprint joint venture
We also transfer raw materials, semifinishedsemi-finished materials and end products among our business segments. Because of this intracompany activity, accounting for our business segments involves:
involves pricing products transferred between our business segments at current market values andvalues.
allocating joint conversion and common facility costs according to usage by our business segment product lines.

GainsUnallocated Items are gains or charges not related to company level initiatives or previous businesses that are not allocated to an individual operating segment are held in Unallocated Items. This includesour current business segments. They include a portion of items such as:as share-based compensation; pension and postretirement costs; foreign exchange transaction gains and losses associated with financing; and the elimination of intersegment profit in inventory and the LIFO reserve.LIFO; foreign exchange transaction gains and losses resulting from changes in exchange rates primarily related to our U.S. dollar denominated cash and debt balances that are held by our Canadian subsidiary; interest income and other and legacy obligations such as environmental remediation and workers compensation.

FOREIGN CURRENCY TRANSLATION
Local currencies are the functional currencies for most of our operations outside the U.S. We translate foreign currencies into U.S. dollars in two ways:
assets and liabilities — at the exchange rates in effect as of our balance sheet date; and
revenues and expenses — at average monthly exchange rates throughout the year.
ESTIMATESEstimates
We prepare our financial statements according to U.S. generally accepted accounting principles (U.S. GAAP). This requires us to make estimates and assumptions during our reporting periods and at the date of our financial statements. The estimates and assumptions affect our:
reported amounts of assets, liabilities and equity;
disclosure of contingent assets and liabilities; and
reported amounts of revenues and expenses.
While we do our best in preparing these estimates, actual results can and do differ from those estimates and assumptions.
FAIR VALUE MEASUREMENTSFair Value Measurements
We use a fair value hierarchy in accounting for certain nonfinancial assets and liabilities including:
long-lived assets (asset groups) measured at fair value for an impairment assessment,assessment;
reporting unitspension plan assets measured at fair value in the first step of a goodwill impairment test,
nonfinancial assets and nonfinancial liabilities measured at fair value in the second step of a goodwill impairment assessment,
assets acquired and liabilities assumed in a business acquisitionvalue; and
asset retirement obligations initially measured at fair value.
The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions.
The fair value hierarchy consists of the following three levels:
Level 1 —1: Inputs are unadjusted quoted prices for identical assets or liabilities traded in an active market.
Level 2: Inputs are quoted prices in activenon-active markets for identical assetswhich pricing inputs are observable either directly or liabilities.indirectly at the reporting date.
Level 2 — Inputs are:
– quoted prices for similar assets or liabilities in an active market;
– quoted prices for identical or similar assets or liabilities in markets that are not active; or
– inputs other than quoted prices that are observable and market-corroborated inputs, which are derived principally from or corroborated by observable market data.
Level 3 —3: Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.
Foreign Currency Translation
Local currencies are the functional currencies for most of our operations outside the U.S. We translate foreign currencies into U.S. dollars in two ways:
assets and liabilities — at the exchange rates in effect as of our balance sheet date; and
revenues and expenses — at average monthly exchange rates throughout the year.
CHANGES IN HOW WE REPORT OUR RESULTS
Changes in how we report our results come from:
accounting changes made upon our adoption of new accounting guidance and
our reclassification of certain balances and results from prior years to make them consistent with our current reporting.reporting and
RECLASSIFICATIONSaccounting changes made upon our adoption of new accounting guidance
Reclassifications
We have reclassified certain balances and results from the prior years to be consistent with our 20152018 reporting. This makes year-to-year comparisons easier. Our reclassifications had no effect on consolidated net earnings or Weyerhaeuser shareholders’ interest. Our reclassifications presentequity.
New Accounting Pronouncements
Lease Recognition
In February 2016, the resultsFASB issued Accounting Standards Update (ASU) 2016-02, which requires lessees to recognize assets and liabilities for the rights and obligations created by those leases and requires leases to be recognized on the balance sheet. The new guidance is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted.

We adopted this standard on January 1, 2019, using the modified retrospective transition approach at the beginning of operations discontinuedthe adoption period through a cumulative-effect adjustment to retained earnings. With this adoption approach, financial information will not be updated and disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. In addition, the standard provides a number of optional practical expedients in 2014 separatelytransition. The adoption resulted in the recognition of additional right-of-use assets and lease liabilities for operating leases of less than 2 percent of our total assets on our Consolidated StatementBalance Sheet. These leases are primarily related to vehicles, equipment, office and warehouse leases disclosed in Note 15: Legal Proceedings, Commitments and Contingencies.
Reclassification of OperationsCertain Amounts from Accumulated Other Comprehensive Loss
In February 2018, the FASB issued ASU 2018-02, which allows for the reclassification of certain income tax effects related to the Tax Cuts and Jobs Act (Tax Act) between “Accumulated other comprehensive loss” and “Retained earnings.” This ASU provides that adjustments to deferred tax liabilities and assets related to a change in tax laws be included in “Income from continuing operations”, even in situations where the related items were originally recognized in “Other comprehensive income (loss).” The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. Adoption of this ASU is to be applied either in the related footnotes.period of adoption or retrospectively to each period in which the effect of the change in the tax laws was recognized. We adopted this ASU during first quarter 2018 using the period of adoption method, which resulted in a reclassification of $253 million from "Accumulated other comprehensive loss" to "Retained earnings" on our Note 3: Discontinued OperationsConsolidated Balance Sheet provides more information about our discontinued operations.due to changes in federal statutory and effective state rates. In general, tax effects unrelated to the Tax Act are released from accumulated other comprehensive loss using the portfolio approach.
NEW ACCOUNTING PRONOUNCEMENTSIn January 2016, the FASB issued ASU 2016-01, which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. We adopted ASU 2016-01 in first quarter 2018, which resulted in a reclassification of accumulated unrealized gains on available-for-sale securities of $9 million from "Accumulated other comprehensive loss" to "Retained earnings" on our Consolidated Balance Sheet.

Revenue Recognition
In May 2014, the Financial Accounting Standards Board (FASB)FASB issued Accounting Standards Update (ASU)ASU 2014-09, a comprehensive new revenue recognition model that requires an entity to recognize revenue to depict the transfer of goods or services to customers at an amount that reflects the consideration it expects to receive in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14, which deferred the effective date of ASU 2014-09 for an additional year. In March 2016, FASB issued ASU 2016-08, which does not change the core principle of the guidance; however, it does clarify the implementation guidance on principal versus agent considerations. In April 2016, FASB issued ASU 2016-10, which clarifies two aspects of ASU 2014-09: identifying performance obligations and the licensing implementation guidance. In May 2016, FASB issued ASU 2016-12, which amends ASU 2014-09 to provide improvements and practical expedients to the new revenue recognition model. In December 2016, the FASB issued ASU 2016-20, which amends ASU 2014-09 for technical corrections and to correct for unintended application of the guidance. In February 2017, FASB issued ASU 2017-05, which clarifies the scope of ASC 610-20 and affects accounting for partial sales of nonfinancial assets.
We plan to adopt theadopted this accounting standard update on January 1, 2018 and may use either2018. The new standard is required to be applied retrospectively to each prior reporting period presented (full retrospective transition method) or retrospectively with the retrospective or cumulative effect transition method. We are evaluatingof initially applying it recognized at the impact that ASU 2014-09 will have on our consolidated financial statements and related disclosures.date of initial application (cumulative effect method). We have not yet selected a transition method nor determinedadopted using the cumulative effect method. The adoption of the standard onnew revenue recognition guidance does not materially affect our ongoing financial reporting.

in the fair value hierarchy. Upon adoption these investments will be presented separately from the fair value hierarchy and reconciled to total investments in our consolidated financial statements and related disclosures.
In July 2015, FASB issued ASU 2015-11, which simplifies the measurement of inventories valued under most methods, including our inventories valued under FIFO – the first-in, first-out – and moving average cost methods. Inventories valued under LIFO – the last-in, first-out method – are excluded. Under this new guidance, inventories valued under these methods would be valued at the lower of cost or net realizable value, with net realizable value defined as the estimated selling price less reasonable costs to sell the inventory. The new guidance is effective prospectively for fiscal periods starting after December 15, 2016 and early adoption is permitted. We expect to adopt ASU 2015-11 on January 1, 2017 and are evaluating the impact on our consolidated financial statements and related disclosures.
In September 2015, FASB issued ASU 2015-16, which requires an acquirer in a business combination to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The update also requires the acquirer to record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects that result from the change to provisional amounts, calculated as if the accounting had been completed at the acquisition date, and to disclose the portion of the amount recorded in current period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The new guidance is effective prospectively for fiscal periods starting after December 15, 2015 and early adoption is permitted. We expect to adopt ASU 2015-16 on January 1, 2016 and have determined that its adoption will not have a material impact on our consolidated financial statements and related disclosures at that time.
In November 2015, FASB issued ASU 2015-17, which simplifies the presentation of deferred income taxes by no longer requiring deferred tax assets and liabilities to be classified as current or noncurrent, instead requiring that all deferred tax assets and liabilities be classified as noncurrent. The new guidance is effective for annual periods starting after December 15, 2017 and early adoption is permitted. We elected to adopt ASU 2015-17 effective October 1, 2015 and have reclassified deferred tax assets and liabilities accordingly in our consolidated balance sheet and in related disclosures for all periods presented.
HOW WE ACCOUNT FOR VARIOUS ITEMS
This section provides information about how we account for certain key items related to:
capital investments,
financing our business and
operations.
ITEMS RELATED TO CAPITAL INVESTMENTS
Key items related to accounting for capital investments pertain to property and equipment, timber and timberlands, impairment of long-lived assets and goodwill.
Property and Equipment
We maintain property accounts on an individual asset basis. Here is how we handle major items:
Improvements to and replacements of major units of property are capitalized.
Maintenance, repairs and minor replacements are expensed.
Depreciation is calculated using a straight-line method at rates based on estimated service lives.
LoggingWe capitalize costs associated with logging roads that we intend to utilize for a period longer than one year. These roads are generallythen amortized — as timber is harvested — at rates based on the volume of timberover an estimated to be removed.service life.
Cost and accumulated depreciation of property sold or retired are removed from the accounts and the gain or loss is included in earnings.
Timber and Timberlands
We carry timber and timberlands at cost less depletion charged to disposals.depletion. Depletion refers to the carrying value of timber that is harvested, lost as a result of casualty or sold.
Key activities affecting how we account for timber and timberlands include:
reforestation,
depletion and
forest management in Canada.
Reforestation. Generally, we capitalize initial site preparation and planting costs as reforestation. We transfer reforestation to a merchantable timber classification when the timber is considered harvestable. That generally occurs after:
15 years in the South and
30 years in the West.
Generally, we expense costs after the first planting as they are incurred or over the period of expected benefit. These costs include:
fertilization,
vegetation and insect control,
pruning and precommercial thinning,
property taxes and
interest.
Accounting practices for these costs do not change when timber becomes merchantable and harvesting starts.
Depletion.Timber depletion. To determine depletion rates, we divide the net carrying value of timber by the related volume of timber estimated to be available over the growth cycle. To determine the growth cycle volume of timber, we consider:
regulatory and environmental constraints,
our management strategies,

WEYERHAEUSER COMPANY > 2015 ANNUAL REPORT AND FORM 10-K65



inventory data improvements,
growth rate revisions and recalibrations and
known dispositions and inoperable acres.

In addition, the duration of the harvest cycle varies by geographic region and species of timber.

Depletion rate calculations do not include estimates for:
future silviculture or sustainable forest management costs associated with existing stands
future reforestation costs associated with a stand's final harvest; and
future volume in connection with the replanting of a stand subsequent to its final harvest
We include the cost of timber harvested in the carrying values of raw materials and product inventories. As these inventories are sold to third parties, we include them in the costCosts of products sold.sales.

WEYERHAEUSER COMPANY > 2018 ANNUAL REPORT AND FORM 10-K65



Forest managementManagement in Canada.We managedmanage timberlands under long-term licenses in various Canadian provinces that are:
granted by the provincial governments;
granted for initial periods of 15 to 25 years; and
renewable provided we meet reforestation, operating and management guidelines.
Calculation of the fees we pay on the timber we harvest:
varies from province to province,
is tied to product market pricing and
depends upon the allocation of land management responsibilities in the license.
Impairment of Long-Lived Assets
We review the carrying value of long-lived assets — including certain identifiable intangibles — for impairment whenever eventsan event or changesa change in circumstances indicatecircumstance ("a triggering event") indicates that the carrying amountvalue of the assetsasset or asset group may not be recoverable.recoverable through future operations. The carrying value is the original cost, less accumulated depreciation and any past impairments recorded. Impaired assets held for use are written down to fair value. Impaired assets held for sale are written down to fair value less cost to sell. We determine fair value based on:
appraisals,
market pricing of comparable assets,
discounted value of estimated cash flows from the asset and
replacement values of comparable assets.
Goodwill
Goodwill is the purchase price minus the fair value of net assets acquired when we buy another entity. We assess goodwill for impairment:
using a fair-value-based approach and
at least annually — at the beginning of the fourth quarter.
In 2015 the fair value of the reporting unit with goodwill substantially exceeded its carrying value.
ITEMS RELATED TO FINANCING OUR BUSINESS
Key items related to financing our business include financial instruments, cash and cash equivalents, accounts payable and concentration of risk.
Financial Instruments
We estimate the fair value of financial instruments where appropriate. The assumptions we use — including the discount rate and estimates of cash flows — can significantly affect our fair-value amounts. Our fair values are estimates and may not match the amounts we would realize upon sale or settlement of our financial positions.
Cash and Cash Equivalents
Cash equivalents are investments with original maturities of 90 days or less. We state cash equivalents at cost, which approximates market.
Accounts Payable
Our banking system replenishes our major bank accounts daily as checks we have issued are presented for payment. As a result, we may have negative book cash balances due to outstanding checks that have not yet been paid by the bank. These negative balances arewould be included in accounts payable"Accounts payable" on our Consolidated Balance Sheet. Changes in these negative cash balances arewould be reported as financing activities in our Consolidated Statement of Cash Flows. We had no negative book cash balances as of December 31, 20152018, and December 31, 20142017.
Concentration of Risk
We disclose customers that represent a concentration of credit risk. As of December 31, 2015,2018, and December 31, 2017, no customer accounted for 10 percent or more of our net sales or accounts receivable balances.sales.
ITEMS RELATED TO OPERATIONS
Key items related to operations include revenue recognition, inventories, shipping and handling costs, income taxes, share-based compensation, pension and other postretirement plans and environmental remediation.
Revenue Recognition
Operations generally recognize revenue upon shipmentRefer to customers. For certain export sales, revenue is recognized when title transfers at the foreign port.
For timberland sales,Note 3: Revenue Recognition for detail on how we recognize revenue when title and possession have been transferred to the buyer and all other criteriaaccount for sale and profit recognition have been satisfied.revenue.
Inventories
We state inventories at the lower of cost or market.net realizable value. Cost includes labor, materials and production overhead. LIFO — the last-in, first-out method — applies to major inventory products held at our U.S. domestic locations. We began to use the LIFO method for domestic products in the 1940s as required to conform with the tax method elected. Subsequent acquisitions of entities added new products under the FIFO — the first-in, first-

WEYERHAEUSER COMPANY > 2015 ANNUAL REPORT AND FORM 10-K66



outfirst-out method — or moving average cost methods that have continued under those methods. The FIFO or moving average cost methods applies to the balance of our domestic raw material and product inventories as well as for all material and supply inventories and all foreign inventories.
Shipping and Handling Costs
We classify shipping and handling costs in the costs"Costs of products sold insales" on our Consolidated Statement of Operations.
Income Taxes
We account for income taxes under the asset and liability method. Unrecognized tax benefits represent potential future funding obligations to taxing authorities if uncertain tax positions the company has taken on previously filed tax returns are not sustained. In accordance with the company’s accounting policy, accrued interest and penalties related to unrecognized tax benefits are recognized as a component of income tax expense.
We recognize deferred tax assets and liabilities to reflect:
future tax consequences due to differences between the carrying amounts for financial reporting purposes and the tax bases of certain items and
operating loss and tax credit carryforwards.
To measure deferred tax assets and liabilities, we:
determine when the differences between the carrying amounts and tax bases of affected items are expected to be recovered or resolved and
use enacted tax rates expected to apply to taxable income in those years.
Share-Based Compensation
We generally measure the fair valueWEYERHAEUSER COMPANY > 2018 ANNUAL REPORT AND FORM 10-K66



Pension and Other Postretirement Benefit Plans
We recognize the overfunded or underfunded status of our defined benefit pension and other postretirement plans on our Consolidated Balance Sheet and recognize changes in the funded status through comprehensive income (loss) in the year in which the changes occur.
Actuarial valuations determine the amount of the pension and other postretirement benefit obligations and the net periodic benefit cost we recognize. The net periodic benefit cost includes:
cost of benefits provided in exchange for employees’ services rendered during the year;
interest cost of the obligations;
expected long-term return on fundplan assets;
gains or losses on plan settlements and curtailments;
amortization of prior service costs and plan amendments over the average remaining service period of the active employee group covered by the plans or the average remaining life expectancy in situations where the plan participants affected by the plan amendment are inactive; and
amortization of cumulative unrecognized net actuarial gains and losses — generally in excess of 10 percent of the greater of the benefit obligation or market-related value of plan assets at the beginning of the year — over the average remaining service period of the active employee group covered by the plans or the average remaining life expectancy in situations where the plan participants are inactive.
Pension plans.We have defined benefit pension plans covering mostapproximately half of our employees. Determination of benefits differs for salaried, hourly and union employees:employees, as follows:
Salaried employee benefits are based on each employee’s highest monthly earnings for five consecutive years during the final 10 years before retirement.
Hourly and union employee benefits generally are stated amounts for each year of service.
Union employee benefits are set through collective-bargaining agreements.
We contribute to our U.S. and Canadian pension plans according to established funding standards. The funding standards for the plans are:
U.S. pension plans — according to the Employee Retirement Income Security Act of 1974; and
Canadian pension plans — according to the applicable provincial pension act and the Income Tax Act.
Postretirement benefits other than pensions.We provide certain postretirement health care and life insurance benefits for some retired employees. In some cases, we pay a portion of the cost of the benefit.Note 9:10: Pension and Other Postretirement Benefit Plansprovides additional information about changes made in our postretirement benefit plans during 20152018 and 20142017.
Environmental Remediation
We accrue losses associated with environmental remediation obligations when such losses are probable and reasonably estimable. Future expenditures for environmental remediation obligations are not discounted to their present value. Recoveries of environmental remediation costs from other parties are recorded as assets when the recovery is deemed probable and does not exceed the amount of losses previously recorded.

NOTE 3: REVENUE RECOGNITION

A majority of our revenue is derived from sales of delivered logs and manufactured wood products. We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, which we adopted on January 1, 2018, using the cumulative effect method. The adoption of the new revenue recognition guidance did not materially affect our Consolidated Statement of Operations, Consolidated Balance Sheet, or Consolidated Statement of Cash Flows.
PERFORMANCE OBLIGATIONS
A performance obligation, as defined in ASC Topic 606, is a promise in a contract to transfer a distinct good or service to a customer. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue at the point in time, or over the period, in which the performance obligation is satisfied.

STRATEGIC EVALUATION OF CELLULOSE FIBERS
On November 8, 2015 Weyerhaeuser announced that the board of directors authorized the exploration of strategic alternatives for its Cellulose Fibers business segment. At this time there can be no assurance that the board's evaluation process will result in any transaction or that any transaction, if pursued, will be consummated.

NOTE 3:DISCONTINUED OPERATIONSPerformance obligations associated with delivered log sales are typically satisfied when the logs are delivered to our customers’ mills or delivered to an ocean vessel in the case of export sales. Performance obligations associated with the sale of wood products are typically satisfied when the products are shipped. The company has elected, as an accounting policy, to treat shipping and handling that is performed after a customer obtains control of the product as an activity required to fulfill the promise to transfer the good; therefore we will not evaluate this requirement as a separate performance obligation.
WeCustomers are generally invoiced shortly after logs are delivered or after wood products are shipped, with payment generally due within a month or less of the invoice date. ASC Topic 606 requires entities to consider significant financing components of contracts with customers, though allows for the use of a practical expedient when the period between satisfaction of a performance obligation and payment receipt is one year or less. Given the nature of our revenue transactions, we have made certain reclassificationselected to utilize this practical expedient.
Performance obligations associated with real estate sales are generally met when placed into escrow and all conditions of closing have been satisfied.
CONTRACT ESTIMATES
Substantially all of the company’s performance obligations are satisfied as of a point in time. Therefore, there is little judgment in determining when control transfers for our consolidated financial statementsbusiness segments as described above.
The transaction price for log sales generally equals the amount billed to reflect discontinued operationsour customer for logs delivered during the accounting period. For the limited number of log sales subject to a long-term supply agreement, the transaction price is variable but is known at the time of billing. For wood products sales, the transaction price is generally the amount billed to the customer for the products shipped but may be reduced slightly for estimated cash discounts and rebates.
There are no significant contract estimates related to WRECO which was previously reported under the Real Estate segment and Unallocated Items.
OPERATIONS INCLUDED IN DISCONTINUED OPERATIONS
Divestiture of WRECO
On July 7, 2014, we completed the following set of transactions resulting in our homebuilding and real estate development business becoming wholly-ownedbusiness.
CONTRACT BALANCES
In general, customers are billed and a receivable is recorded as we ship and/or deliver wood products and logs. We generally receive payment shortly after products have been received by TRI Pointe Homes, Inc. (TRI Pointe):our customers. Contract asset and liability balances are immaterial.
For real estate sales, the distribution of shares of WRECO to our shareholderscompany receives the entire consideration in exchange for 59 million shares of our common stock; andcash at closing.
the merger of WRECO into a special purpose subsidiary of TRI Pointe, with WRECO surviving the merger and becoming a wholly-owned subsidiary of TRI Pointe.
Collectively, these transactions are referred to as the “Real Estate Divestiture”.
During June 2014, our wholly-owned subsidiary, WRECO, issued $900 million of unsecured and unsubordinated senior debt obligations. The net proceeds after deducting the discount, underwriting fees and issuance costs were $870 million. At the close of the Real Estate Divestiture in July 2014, WRECO used $744 million of the debt proceeds to repay intercompany debt and interest to Weyerhaeuser Company. The newly issued

NOTE 4:DISCONTINUED OPERATIONS AND OTHER DIVESTITURES

OPERATIONS DIVESTED

On September 1, 2017, we completed the sale of our Uruguay timberlands and manufacturing operations, to a consortium led by BTG Pactual's Timberland Investment Group (TIG), including other long-term investors, for $403 million of cash proceeds. Due to the impairment of our Uruguayan operations recorded during second quarter 2017 (refer to Note 18: Charges for Integration and Restructuring, Closures and Asset Impairments), no material gain or loss was recorded as a result of this sale.

The sale of our Uruguayan operations was not considered a strategic shift that had or will have a major effect on our operations or financial results and therefore did not meet the requirements for presentation as discontinued operations.


WEYERHAEUSER COMPANY > 2018 ANNUAL REPORT AND FORM 10-K70



DISCONTINUED OPERATIONS
During 2016, we entered into three separate transactions to sell our Cellulose Fibers business. As a result of these transactions, the company recognized a pretax gain on disposition of $789 million and total cash proceeds of $2.5 billion in the second half of 2016. These transactions consisted of:

sale of our Cellulose Fibers liquid packaging board business to Nippon Paper Industries Co., Ltd for $285 million in cash proceeds, which closed on August 31, 2016;
sale of our Cellulose Fibers printing papers joint venture to One Rock Capital Partners, LLC for $42 million in cash proceeds, which closed on November 1, 2016; and
sale of our Cellulose Fibers pulp business to International Paper for $2.2 billion in cash proceeds, which closed on December 1, 2016.

The results of operations for our pulp and other WRECO assets and liabilities, including $5 million cashliquid packaging board businesses, along with our interest in our printing papers joint venture, were reclassified to discontinued operations during our 2016 reporting year. These results have been summarized in "Earnings from discontinued operations, net of income taxes" on hand, were acquired by TRI Pointe when WRECO becameour Consolidated Statement of Operations for each period presented. We did not reclassify our Consolidated Statement of Cash Flows to reflect discontinued operations. Cellulose Fibers was previously disclosed as a wholly-owned subsidiaryseparate reportable business segment. Retained indirect corporate overhead costs previously allocated to Cellulose Fibers are now reported as part of TRI Pointe at the closingUnallocated Items.

We used $1.7 billion of the transaction. Additionally, $32 million related toafter-tax proceeds from the adjustment amount payable pursuant to the termssale of the transaction agreement was paid to TRI Pointe. Our net cash proceeds in connection with the Real Estate Divestiture totaled $707 million.our Cellulose Fibers business segment for repayment of debt during 2016.
Prior to the distribution of WRECO shares to our shareholders, WRECO was a wholly-owned subsidiary. Concurrent with the distribution to shareholders, WRECO ceased being a subsidiary.

NOTE 4:ACQUISITIONS
PENDING MERGER WITH PLUM CREEK
On November 6, 2015 Weyerhaeuser Company and Plum Creek Timber, Inc., entered into an Agreement and Plan of Merger (“Merger Agreement”) pursuant to which Plum Creek will merge with and into Weyerhaeuser Company with Weyerhaeuser continuing as the surviving corporation. Under the terms of the Merger Agreement, Plum Creek shareholders will receive 1.60 shares of Weyerhaeuser common shares for each share of Plum Creek common stock at the closing date. Plum Creek is a REIT that owns and manages timberlands in the United States. In addition Plum Creek produces wood products, develops opportunities for mineral and other natural resource extraction, and develops and sells real estate properties.
Because the exchange ratio was fixed at the time of the merger agreement and the market value of our common stock will continue to fluctuate, the total value of the consideration exchanged will not be determinable until the closing date. The number of shares to be issued with respect to Plum Creek stock awards will not be determinable until the closing of the transaction. We have estimated the total consideration expected to be issued to Plum Creek shareholders in the merger to be 278 million shares of our common stock based on the 1.60 exchange ratio and the number of shares of Plum Creek common stock issued and outstanding as of November 30, 2015.
The merger agreement has been approved by both companies' board of directors. The closing of the merger is subject to approval by the shareholders of Plum Creek, the approval by our shareholders of the issuance of Weyerhaeuser Company common stock to Plum Creek's shareholders, receipt of certain regulatory approvals and other conditions specified in the merger agreement. The merger is expected to close in the first quarter of 2016.
LONGVIEW TIMBER PURCHASE
On July 23, 2013, we purchased 100 percent of the equity interests in Longview Timber LLC (Longview Timber) for $1.58 billion cash and assumed debt of $1.07 billion, for an aggregate purchase price of $2.65 billion. Longview Timber was a privately-held Delaware limited liability company engaged in the ownership and management of approximately 645,000 acres of timberlands in Oregon and Washington. We believe Longview Timber has productive lands with favorable age class distribution that will provide us with optionality for harvest. Earnings, assets and liabilities from this business are reported as part of the Timberlands segment beginning in third quarter 2013.

HOW WE CALCULATE BASIC AND DILUTED NET EARNINGS PER SHARE
"Basic earnings" per share is net earnings available to common shareholders divided by the weighted average number of our outstanding common shares, including stock equivalent units where there is no circumstance under which those shares would not be issued.

We use the treasury stock method to calculate the dilutive effect of our outstanding stock options, restricted stock units and performance share units. Share-based payment awards that are contingently issuable upon the achievement of specified performance or market conditions are included in our diluted earnings per share calculation in the period in which the conditions are satisfied.
We use the if-converted method to calculate the effect of our outstanding preference shares. In applying the if-converted method, conversion is not assumed for purposes of computing diluted earnings per share if the effect would be antidilutive. Preference shares are antidilutive whenever the amount of the dividend declared in or accumulated for the current period per common share obtainable on conversion exceeds diluted earnings per share exclusive of the preference shares.
Preference shares are evaluated for participation on a quarterly basis to determine whether two-class presentation is required. Preference shares are considered to be participating as of the financial reporting period end to the extent they would participate in dividends paid to common shareholders. Preference shares are not considered participating for the years ended December 31, 2015 and 2014. Under the provisions of the two-class method, basic and diluted earnings per share would be presented for both preference and common shareholders.
SHARES EXCLUDED FROM DILUTIVE EFFECT
The following shares were not included in the computation of diluted earnings per share because they were either antidilutive or the required performance or market conditions were not met. Some or all of these shares may be dilutive potential common shares in future periods.
We issued 13.8 million 6.375 percent Mandatory Convertible Preference Shares, Series A on June 24, 2013. We do not include these shares in our calculation of diluted earnings per share because they are antidilutive. See Note 4: Acquisitions.

NOTE 8: EQUITY AFFILIATES9: RELATED PARTIES
WeThis note provides details about and our transactions with related parties. For the years presented, our related parties have investments in unconsolidated equity affiliates overconsisted of:
Real Estate Development Ventures,
our Twin Creeks Venture, and
special-purpose entities (SPEs).
REAL ESTATE DEVELOPMENT VENTURE
WestRock-Charleston Land Partners, LLC (WR-CLP) is a limited liability company which we have significant influence that we account for usingholds residential and commercial real estate development properties, currently under development (Class A Properties) and higher-value timber and development lands (Class B Properties) (referred to collectively as the Real Estate Development Ventures). The company uses the equity method with taxes providedfor both its Class A and Class B interests of 3 percent and 50 percent, respectively. Our share of the equity earnings is included in the net contribution to earnings of our Real Estate & ENR segment.
We are not the primary beneficiary of WR-CLP and we are not committed to make any material capital contributions during the remaining term of the venture, which expires in 2020. We do not intend to provide any additional sources of financing for WR-CLP.
The carrying amount of our investment in WR-CLP was $31 million at December 31, 2017. During 2018, all remaining capital invested in WR-CLP was returned through distributions. At December 31, 2018, we no longer carry an investment related to WR-CLP. Additionally, we had a $1 million gain on undistributed earnings.investment from the joint venture during 2018. We record our share of net earnings on the investment within "Earnings (loss) from equity affiliates""Interest income and other" in our Consolidated Statement of Operations in the period in which earnings are recorded by the affiliates.

Ownership Redemption, Agreement Termination and Sale Recognition
As of December 31, 2015,During October 2017, we hold a 50redeemed our 21 percent ownership interest in North Pacific Paper Corporation (NORPAC). NORPAC owns and operates a newsprint manufacturing facility in Longview, Washington. Our share of the net earnings of NORPAC is reported in our Cellulose Fibers segment.
In the fourth quarter of 2015, it was determined that the joint venture’s book value of certain long-lived assets was not recoverable and an impairment charge was recorded to measure these assets at fair value. The fair value of the asset group was estimated based on a combination of income and market approaches using significant unobservable inputs. Key assumptions include (a) the timing and amounts of future cash flows related to the asset group’s operations, (b) discount rates applicable to the future cash flows ranging from 10.5 percent to 14 percent and (c) earnings multiples of other entities’ asset groups deemed to be similar to the asset group. Weyerhaeuser’s earnings include an $84 million chargeTwin Creeks Venture for our share of this asset impairment. Weyerhaeuser also recorded a related additional tax benefit of $28$108 million in its provision for income taxescash. We did not recognize a material gain or loss on the redemption of our ownership interest. The cash received was classified as a result of the reduction of deferred tax liabilities associated with the reductioncash flow from investing activities in the book basis of the investment in this equity affiliate. As such, the net charge to Weyerhaeuser related to this item was $56 million in the fourth quarter of 2015.
During 2014, Catchlight Energy was dissolved. We received no proceeds from the dissolution.
During 2013, we sold part of our investment in Liaison Technologies Inc. and recognized a $10 million pretax gain, which is recorded in "Interest income and other" on our Consolidated Statement of OperationsCash Flows and within Unallocated Items. Our remaining investment is accounted for under the cost method..

Doing BusinessFormation and Operations
On April 1, 2016, we contributed approximately 260,000 acres of our Southern timberlands with Affiliatesan agreed-upon value of approximately $560 million to Twin Creeks Timber, LLC (Twin Creeks Venture), in exchange for cash of approximately $440 million and a 21 percent ownership interest. The other members contributed cash of approximately $440 million for a combined 79 percent ownership interest.
In conjunction with contributing to the venture, we entered into a separate agreement to manage the timberlands owned by the Twin Creeks Venture, including harvesting activities, marketing and log sales activities, and replanting and silviculture activities. This management agreement guaranteed the Twin Creeks Venture an annual return equal to 3 percent of the contributed value of the managed timberlands in the form of minimum quarterly payments from Weyerhaeuser. This agreement also required us to annually distribute 75 percent of any profits earned by us in excess of the minimum quarterly payments. The management agreement was cancellable at any time by Twin Creeks Timber, LLC, and otherwise would expire on April 1, 2019.
The guaranteed return that the management agreement required Weyerhaeuser to provide to the Twin Creeks Venture constituted continuing involvement in the timberlands that we contributed to the venture. This continuing involvement prohibited the recognition of the contribution as a sale and required application of the deposit method to account for the cash payment received. By applying the deposit method to the contribution of timberlands to the venture:
Our receipt of $440 million proceeds from the contribution of timberlands to the venture was recorded as a noncurrent liability.
The contributed timberlands continued to be reported within the "Timber and timberlands at cost, less depletion charged to disposals" on our balance sheet as of December 31, 2016.
No gain or loss was recognized related to the formation or redemption in our Consolidated Statement of Operations.
Our balance sheet as of December 31, 2016 did not reflect our 21 percent ownership interest in the Twin Creeks Venture.
The receipt of $440 million in 2016 was classified as a cash flow from investing activities in our Consolidated Statement of Cash Flows. The cash proceeds from our contribution of timberlands were used for share repurchases.

In conjunction with the redemption and termination discussed above, we also entered an agreement to sell 100,000 acres of Southern timberlands to Twin Creeks for $203 million. The sale, which included 80,000 acres of timberlands in Mississippi and 20,000 acres in Georgia, closed December 29, 2017. The sale resulted in a $99 million gain recognized during fourth quarter 2017.
SPECIAL-PURPOSE ENTITIES
From 2002 through 2004, we sold certain nonstrategic timberlands. As a result of these sales, buyer-sponsored and monetization special purpose entities (SPEs) were formed. We are the primary beneficiary and consolidate the assets and liabilities of the SPEs involved in these transactions.
The assets of the buyer-sponsored SPEs are financial investments which consist of bank guarantees. These bank guarantees are in turn backed by bank notes, which are the liabilities of the monetization SPEs. Interest earned from the financial investments within the buyer-sponsored SPEs is used to pay interest accrued on the corresponding monetization SPE’s note.
We provide goods and services to NORPAC, including raw materials and support services. The amounts paid to Weyerhaeuser by NORPAC for goods and services were:
$197 million in 2015,
$195 million in 2014 and
$203 million in 2013.
In addition, we manage cash for NORPAC under a services agreement. Weyerhaeuser holds the cash and records a payable balance to NORPAC, which is included in accounts payablehave an equity interest in the accompanyingmonetization SPEs, but no ownership interest in the buyer-sponsored SPEs.

DEFINED BENEFIT PLANS WE SPONSOR
OVERVIEW OF PLANS
The defined benefit pension plans we sponsor in the U.S. and Canada differ according to each country’s requirements. In the U.S., we have plans that qualify under the Internal Revenue Code (qualified plans), as well as plans for select employees that provide additional benefits not qualified under the Internal Revenue Code (nonqualified plans). In Canada, we have plans that are registered under the Income Tax Act and applicable provincial pension andacts (registered plans), as well as nonregistered plans for select employees that provide additional benefits that may not be registered under the Income Tax Act or provincial pension acts (nonregistered plans). We also offer other postretirement benefit plans in the U.S. and Canada, including retiree medical and life insurance plans.
Measurement DateActions to Reduce Pension Plan Obligations
We measureDuring 2018, we offered select U.S. terminated vested plan participants the fair valueopportunity to elect an immediate lump sum distribution. Lump sum distributions were paid from plan assets totaling $664 million during fourth quarter 2018. In connection with this transaction, we have recorded a settlement charge of $200 million during fourth quarter 2018, accelerating the recognition of previously unrecognized losses in “Accumulated other comprehensive loss”, that would have been recognized in subsequent periods. The settlement triggered a plan remeasurement, however due to the short period between the settlement and our normal year-end remeasurement, the effects were insignificant to the net periodic benefit costs and therefore not recorded.
In January 2019, we transferred approximately $1.5 billion of U.S. qualified pension plan assets and pension and other postretirement benefit obligations asliabilities to an insurance company through the purchase of the enda group annuity contract. We expect to record an additional settlement charge of our fiscal year. The fair value of pension plan assets are estimated atapproximately $450 million in connection with this transaction during first quarter 2019.
To maintain the end of the year and are revised in the first half of the following year when the information needed to finalize fair values is received. Additionally, we receive updated census data that is used to estimate our projected benefit obligation. As a result of the Real Estate Divestiture as well as our selling, general and administrative cost reduction initiative, we remeasured our U.S. qualified pension plan's current funded status in connection with these transactions, we contributed $300 million to the plan during third quarter 2014. There were no significant events that triggered a special remeasurement in 2015 or 2013.
EFFECTS OF SIGNIFICANT TRANSACTIONS AND EVENTS
The information that is provided in this note is affected by the following transactions and events.
Amendments of Pension and Other Postretirement Benefit Plans2018. Refer to Note 21: Income Taxes for Salaried Employees
Pension Benefit Plan Amendments
During fourth quarter 2013, we ratified an amendment to the Weyerhaeuser Pension Plan that closes the plan to newly hired and rehired salaried or non union employees effective January 1, 2014. Certain union employee groups adopted similar amendments effective at other dates. Beginning at the effective date, new hires and rehires into groups affected by these amendments will receive a company contribution for retirement in their 401(k) plan. The change was announced in December 2013.

WEYERHAEUSER COMPANY > 2015 ANNUAL REPORT AND FORM 10-K75



During fourth quarter 2013, we ratified amendments to the Weyerhaeuser Company Limited Retirement Plan for Non-Union Employees and the Retirement Plan for Non-Union Employees of Weyerhaeuser Company Limited at Grand Prairie, Alberta and Grande Cache, Alberta that (1) closes these plans to new hires and rehires effective January 1, 2014 and (2) changes the early retirement reduction for current employees enrolled in these plans, effective for future years of service beginning January 1, 2016. These changes were announced to participants in December 2013.
There were no material pension benefit plan amendments in 2014 or 2015.
Postretirement Medical and Life Insurance Benefit Plan Amendments
During fourth quarter 2014, the decision was ratified to reinstate or modify available options for U.S. and Canadian postretirement benefits for certain retirees. As a result, our postretirement obligation increased by $45 million.
During fourth quarter 2013, the decision was ratified to eliminate Company funding of the Post-Medicare Health Reimbursement Account (HRA) for certain salaried retirees after 2014. This change was communicated to affected retirees during January 2014. As a result, we recognized a pretax gain of $151 million in 2014 from this plan amendment.
There were no material postretirement medical or life insurance benefit plan amendments in 2015.
Midyear Remeasurement of Assets and Liabilities
Our pension plans are typically remeasured as of fiscal year-end unless a significant event occurs that requires remeasurement. As a result of the Real Estate Divestiture as well as our selling, general and administrative cost reduction initiative, we remeasured our U.S. qualified pension plan during third quarter 2014. There were no midyear remeasurements during 2015.
The net effect of the 2014 remeasurement was as follows:
We recognized a $9 million charge in third quarter 2014 for curtailments and special termination benefits. Of this amount, $6 million is included in the net gain on the Real Estate Divestiture and is presented in "Earnings from discontinued operations, net of income taxes" in our Consolidated Statement of Operations. The remaining $3 million is included in "Charges for restructuring, closures and impairments" in our Consolidated Statement of Operations.
The funded status of our U.S. qualified pension plan was reduced by $291 million primarily as a result of a decline in the discount rate used to calculate the projected benefit obligation and also due to asset performance and curtailment and special terminations. The discount rate used to remeasure the pension plans’ liabilities was changed from a rate of 4.9 percent at December 31, 2013 to rates reflective of current bond ratesdetails on the remeasurement date. A discount ratetax effects of 4.4 percent was used as of July 7, 2014. There was no change to the expected rate of return assumption.
Deferred tax liabilities decreased $108 million.
Total equity decreased $183 million for changes in "Cumulative other comprehensive loss", reflecting the net effect of the items discussed above. Amounts deferred in cumulative other comprehensive loss will be amortized into net periodic pension cost (credits) in future periods.this transaction.
FUNDED STATUS OF PLANS WE SPONSOR
The funded status of the plans we sponsor is determined by comparing the projected benefit obligation with the fair value of plan assets at the end of the year.

Changes in actuarial assumptions decreased liabilities by $343 million as of the end of 2015 and had a positive effect The following table demonstrates how our plans' funded status is reflected on the funded status of the pension and postretirement plans. The primary drivers were the adoption of updated mortality tables for the U.S. pension and postretirement plans and changes in discount rates. The Company elected to implement the longevity assumption published by the Society of Actuaries in October 2015, effective December 31, 2015. Discount rates increased from 4.10 percent at the end of 2014 to 4.50 percent at the end of 2015 for the U.S. pension plans, and increased from 3.60 percent at the end of 2014 to 4.00 percent at the end of 2015 for U.S. postretirement. The discount rates increased from 3.90 percent at the end of 2014 to 4.00 percent at the end of 2015 for the Canadian pension plans, and increased from 3.80 percent at the end of 2014 to 3.90 percent at the end of 2015 for Canadian postretirement.
Our qualified and registered pension plans and a portion of our nonregistered pension plans are funded. We contribute to these plans according to established funding standards. The nonqualified pension plan, a portion of the nonregistered pension plans, and the other postretirement benefit plans are unfunded. For the unfunded plans, we pay benefits to retirees from our general assets as they come due.
The values reported for our pension plan assets at the end of 2015 and 2014 were estimated. Additional information regarding the year-end values generally becomes available to us during the first half of the following year. We increased the fair value of plan assets by $57 million to reflect final valuations as of December 31, 2014.
During 2015, we contributed $33 million for our Canadian registered plans, we made contributions and benefit payments of $3 million for our Canadian nonregistered pension plans and made benefit payments of $24 million for our nonqualified pension plans.

We estimate the fair value of pension plan assets based upon the information available during the year-end reporting process. In some cases, primarily with regard to private equity funds, the available information consists of net asset values as of an interim date, plus cash flows and market events between the interim date and the end of the year. We update the year-end estimated fair value of pension plan assets during the first half of the next year to incorporate year-end net asset values received after we have filed our Annual Report on Form 10-K. During second quarter 2018, we recorded an increase in the beginning of year fair value of the pension assets of $44 million, or less than 1 percent.
During second quarter 2018, we also updated our mortality assumption and census data used to estimate our projected benefit obligation for our U.S. qualified pension plan. We recorded an adjustment to our projected benefit obligation, incorporating updated census data and applying new company-specific mortality data. As a result of these updates, the beginning of year pension projected benefit obligation decreased by $155 million, or approximately 2 percent. The net effect of these updates, including the update to the pension assets, was a $199 million improvement in funded status

PENSION ASSETS
Our Investment Policies and Strategies
Our investment policies and strategies guide and direct how we managethe funds are managed for the benefit plans we sponsor. These funds include our:
U.S. Pension Trust — funds our U.S. qualified pension plans;
Canadian Pension Trust — funds our Canadian registered pension plans; and
Retirement Compensation Arrangements — fund a portion of our Canadian nonregistered pension plans.
U.S. and Canadian Pension Trusts
Our U.S.As of the end of 2018, we have begun to shift pension trust holdsplan assets to an allocation that will more closely match the pension plan liability profile going forward. The former investment strategy included investments in hedge funds, private equity funds, derivative instruments and other investments. These asset classes are now generally in redemption and run-off mode however, given the long-term nature of these investments, they will continue to comprise a significant portion of the plan assets for our U.S. qualified pension plans, while our Canadian pension trust holds the fundsseveral years. We expect all investments in redemption to be redeemed at amounts materially consistent with their net asset values. As these investments are redeemed or liquidated, cash proceeds available for our Canadian registered pension plans.
Our strategy within the trusts is to invest:
directly in a diversified mix of nontraditional investments; and
indirectly through derivatives to promote effective use of capital, increase returns and manage associated risk.
Consistent with past practice andinvestment will be invested in accordance with our revised investment guidelines established bystrategy.
The revised investment strategy targets an initial 60 percent allocation to growth assets and a 40 percent allocation to liability hedging assets. We expect to increase the company’s investment committee,allocation to liability hedging assets over time as the investment managersfunded status of the company’s pension plan asset portfolios utilize a diversified set of investment strategies.
Our directimproves. Growth assets include new investments include:
cashin global equities, hedge funds, which are generally in redemption, and short-term investments,
hedge funds,
private equity
real estate fund investments assets, which are generally in run-off mode. Liability hedging assets include corporate credit and
common and preferred stocks.
Our indirect investments include:
equity index derivatives,
government issued fixed income derivativessecurities, treasury futures and interest rate swaps selected to align with the plan liabilities.
swaps and other derivative instruments.
The overall return for our pension trusts includes:
returns earned on our direct investments and
returns earned on the derivatives we use.
Cash and short-term investments generally consist of include highly liquid money market and government securities and are primarily held to fund benefit payments, capital calls, margin requirements or to meet regulatory requirements. Cash at December 31, 2018, includes amounts that will be invested in liability hedging assets such as fixed income investments.
Fixed income investments include publicly traded corporate and margin requirements.government issued debt. These bonds have varying maturities, credit quality and sector exposure, and are selected to align with the duration of our plan liabilities. The fixed income investments are invested largely in line with long corporate bond indices.
Hedge fund and related investments generally consist of are privately-offered managed pools primarily structured as limited liability entities, with the generalentities. General members or partners of suchthese limited liability entities servingserve as portfolio managermanagers and are thus being responsible for the fund’s underlying investment decisions. Generally, these funds have varying degrees of liquidity and redemption provisions. Underlying investments within these funds may include long and short public and private equities, corporate, mortgage and sovereign debt, options, swaps, forwards and other derivative positions. These funds may also usehave varying degrees of leverage.leverage, liquidity, and redemption provisions.
Private equity and related investments consist of are investments in private equity, mezzanine, distressed, co-investments and other structures. Private equity funds generally participate in buyouts and venture capital of limited liability entitiesthrough unlisted equity and debt instruments. These funds may also employ borrowingborrow at the underlying entity level. Mezzanine and distressed funds generally follow strategies of investinginvest in the debt of public or private companies with additional participation through warrants or other equity type options.
Real estate fund investments in real property may be initiated through private transactions between principals or public market vehicles such as real estate investment trusts and are generally held in limited liability entities.
Common and preferred stocks are equityDerivative instruments that generally have resulted from transactions related to private equity investment holdings.
Swaps and other derivative instruments generally are comprised of swaps, futures, forwards or options. In accordance with our investment riskEquity and return objectives, some of these instrumentsfixed income index derivatives are utilizedused to achieve target equity and bond asset exposure or to reduce exposure to certain market risks orrisks. Foreign currency derivatives reduce exposure to help manage the liquidity of our investments. The resulting asset mix achieved is intended to allow the assets to perform comparably with established benchmarks. Others, mainly totalcertain currency risks. Total return swaps with limited exchange of principal, are designed to gainenable exposure to the return characteristics of specific financial strategies.
All swap, forward and option contracts are executed in a diversified manner through a numberstrategies with limited exchange of financial institutions and in accordance with our investment guidelines.
Retirement Compensation Arrangements
Retirement Compensation Arrangements fund a portion of our Canadian nonregistered pension plans.
Under Retirement Compensation Arrangements, our contributions are split:
50 percent to our investments in a portfolio of equities; and
50 percent to a noninterest-bearing refundable tax account held by the Canada Revenue Agency — as required by Canadian tax rules.

WEYERHAEUSER COMPANY > 2015 ANNUAL REPORT AND FORM 10-K78principal.



The Canadian tax rules requirement means that — on average, over time — approximately 50 percent of our Canadian nonregistered pension plans’ assets do not earn returns.
Managing Risk
Investments and contracts, in general, are subject to risk, including market price, liquidity, currency, interest rate and credit risks. We have established governance practices to manage certain risks. The following provides an overview of these risks and describes actions we take to mitigate the potential adverse effects of these risks on the performance of our pension plan assets. Generally, we manage these risks through:
selection and diversification of managers and strategies,
use of limited-liability vehicles,
diversification and
constraining risk profiles to predefined limits on the percentage of pension trust assets that can be invested in certain categories.
Market price risk is the risk that the future value of a financial instrument will fluctuate as a result of changes in its market price, whether caused by factors specific to the individual investment, its issuer, or any other market factor that may affect its price. We attempt to mitigate market price risk on the company’s pension plan asset portfolios by investing in a diversified set of assets whose returns exhibit low correlation to those of traditional asset classes and each other. In addition, we and our investment advisers monitor the investments on a regular basis to ensure the decision to invest in particular assets continues to be suitable, including performing ongoing qualitative and quantitative assessments and comprehensive investment and operational due diligence. Special attention is paid to organizational changes made by the underlying fund managers and to changes in policy relative to their investment objectives, valuation, hedging strategy, degree of diversification, leverage, alignment of fund principles and investors, risk governance and costs.
Liquidity risk is the risk that the pension trusts will encounter difficulty in meeting obligations associated with their financial liabilities. Our financial obligations as they relate to the pension plans generally consist of distributions and redemptions payable to pension plan participants, payments to counterparties and fees to service providers. As established, pension plan assets primarily consist of investments in limited liability pools for which there is no active secondary market. As a result, the investments may be illiquid. Further, hedge funds are subject to potential restrictions that may affect the timing of the realization of pending redemptions. Private equity funds, including those private equity funds that invest in real estate assets, are subject to distribution and funding schedules that are set by the private equity funds’ respective managers and market activity, and the period over which the funds are expected to liquidate is uncertain and dependent upon realization of the respective funds' underlying investments which will vary over time. To mitigate liquidity risk on the company’s pension plan asset portfolios, private equity portfolios has been diversified across different vintage years and strategies and hedge fund portfolios have been diversified across investment fund managers, strategies and funds that possess varying liquidity provisions. By doing so, the company seeks to maintain a liquidity profile wherin the potential liquidity offered by the pension plan assets is diversified over time. For instance, under normal operating conditions, the frequency by which investments in hedge funds may be redeemed ranges from daily to every three years with notice periods as few as five days to as much as a year. This liquidity profile, however, can be impacted by existing terms that permit redemption restrictions and decisions by underlying fund managers to create illiquid side pockets, adopt a fund liquidation strategy or suspend redemptions altogether. In addition, the investment committee regularly reviews cash flows of the pension trusts and sets appropriate guidelines to address liquidity needs.
Currency risk arises from holding pension plan assets denominated in a currency other than the currency in which its liabilities are settled. Such risk is managed generally through notional contracts designed to hedge the net exposure to non-functional currencies.
Interest rate risk is the risk that a change in interest rates will adversely affect the fair value of fixed income securities. The pension trust’s primary exposure to interest rate risk is indirect and through their investments in limited liability pools. Such indirect exposure is managed by the respective fund managers in conjunction with their investment level decisions and predefined investment mandates.
Credit risk relates to the extent to which failures by counterparties to discharge their obligations could reduce the amount of future cash flows on hand at the balance sheet date. The pension trusts’ exposure to counterparty credit risk is reflected in settlement receivables from derivative contracts within the pension plan assets. In evaluating credit risk, we will often be dependent upon information provided by the counterparty or a rating agency, which may be inaccurate. We decrease exposure to credit risk by only dealing with highly-rated financial counterparties, and as of year-end, our counterparties each had a credit rating of at least A from Standard and Poor’s.
We further manage this risk through:
diversification of counterparties,
predefined settlement and margining provisions and
documented agreements.
We expect that none of our counterparties will fail to meet its obligations. Also, no principal is at risk as a result of these types of investments. Only the amount of unsettled net receivables is at risk.
We are also exposed to credit risk indirectly through counterparty relationships struck by the underlying managers of investments in limited liability pools. This indirect exposure is mitigated through a due diligence process, which focuses on monitoring each investment fund to ensure the decision to invest in or maintain exposure to a fund continues to be suitable for the pension plans’ asset portfolios.
While we do not target specific direct investment or derivative allocations, we have established guidelines on the percentage of pension trust assets that can be invested in certain categories to provide diversification by investment type fund and investment managers, as well as to manage overall liquidity.

Assets withinRetirement Compensation Arrangements
Retirement compensation arrangements fund a portion of our Canadian nonregistered planspension plans. As required by Canadian tax rules, approximately 50 percent of these assets are invested into a noninterest-bearing refundable tax account held by the Canada Revenue Agency. This portion of the portfolio does not earn returns. The remaining portion is invested in a portfolio of equities.
Managing Risk
Investments and contracts are subject to risks including market price, liquidity, currency, interest rate and credit risks. The following provides an overview of these risks and describes governance processes and actions we take to mitigate these risks on our pension plan asset portfolios.
Market price risk is the risk that market fluctuations will adversely affect the value of plan assets. The trusts mitigate market price risk by investing in a diversified portfolio. In addition, we and our investment advisers perform regular monitoring with ongoing qualitative assessments, quantitative assessments, and comprehensive investment and operational due diligence.
Liquidity risk is the risk that the trust will not be able to settle liabilities such as payments to participants, counterparties, and service providers. Plan investments in limited liability pools with no active secondary market may be illiquid. Private equity funds are allowedsubject to manage were invested as follows:distribution and funding schedules set by fund managers and market activity. Hedge funds may also be subject to restrictions that delay redemptions. To mitigate liquidity risk, private equity portfolios have been diversified across different vintage years and strategies, and hedge fund portfolios have been

diversified across investment fund managers, strategies and liquidity provisions. In addition, the investment committee regularly reviews cash flows of the pension trusts and sets appropriate guidelines to address liquidity needs. With the change in investment strategy and a larger percentage of the plan assets invested in more liquid instruments such as publicly traded fixed income investments, liquidity risk is greatly reduced.
Currency risk arises from holding plan assets denominated in a currency other than the currency in which its liabilities are settled. Currency risk is generally managed through notional contracts designed to hedge net exposure to non-functional currencies. With the change in investment strategy, currency risk will be mitigated going forward by investing more of the Canadian plan assets in Canadian dollar investments.
Interest rate risk exists on both the asset and liability side, and is the risk that a change in interest rates will adversely affect the fair value of interest rate securities or liabilities, thereby affecting the overall funded status. With the change in investment strategy to more closely match the plan liabilities, interest rate risk will be greatly reduced.
Credit risk is the risk that counterparties’ failure to discharge their obligations could affect cash flows. The trusts have exposure through investments in fixed income securities. This risk is mitigated by investing in a diversified portfolio. The trusts also have exposure through settlement receivables from derivative contracts. Only the amount of unsettled net receivables is at risk for these types of investments, and no principal is at risk. We decrease credit risk exposure by only dealing with highly-rated financial counterparties; as of year-end, our counterparties each had a credit rating of at least A from S&P.We further manage this risk through diversification of counterparties, predefined settlement and margining provisions and documented agreements.
We are also exposed to credit risk indirectly through counterparty relationships initiated by underlying managers of investments in limited liability pools. This risk is mitigated through initial due diligence and ongoing monitoring processes.
Valuation of Our Plan Assets
The pensionPension assets are stated at fair value as of the reporting date. Fair value is based uponon the amount that would be received to sell an asset or paid to transfersettle a liability in an orderly transaction between market participants at the reporting date. We do not value pension investments based upon aconsider forced or distressed sale scenario.scenarios. Instead, we consider both observable and unobservable inputs that reflect assumptions applied by market participants when setting the exit price of an assetor liability in an orderly transaction within the principal market offor that asset or liability.
We value the pension plan assets based upon the observability of exit pricing inputs and classify pension plan assets based upon the lowest level input that is significant to the fair value measurement of the pension plan assets in their entirety. The fair value hierarchy we follow is outlined below;is:
Level 1: Inputs are unadjusted quoted prices for identical assets andor liabilities traded in an active market.
Level 2: Inputs are quoted prices in non-active markets for which pricing inputs are observable either directly or indirectly at the reporting date.
Level 3: Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.
The pension assetsInvestments for which fair value is measured using the net asset value per share as a practical expedient are comprised of cash and short-term investments, derivative contracts, common and preferred stock and fund units. The fund units are typically limited liability interests in hedge funds, private equity funds, real estate funds and cash funds. Each of these assets participates in its own unique principal market.not categorized within the fair value hierarchy.
Cash and short-term investments when held directly, are valued at cost.cost, which approximates market.
Common and preferred stocksFixed income investments are valued at exit prices quoted in the public markets.active or non-active markets or based on observable inputs.
Derivative contracts held by our pension trusts are not publicly tradedHedge funds, private equities, and each derivative contract is specifically negotiated with a unique financial counterparty and references either illiquidrelated fund units or a unique number of synthetic units of a publicly reported market index. The derivative contracts are valued based upon valuation statements received from the financial counterparties.
Fund units are valued based uponon the net asset values of the funds which we believefunds. These values represent the per-unit pricesprice at which new investors are permitted to invest and the prices at which existing investors are permitted to exit. To the degreeWhen net asset values as of the end of the year have not been received, we useestimate fair value by adjusting the most recently reported net asset values and adjust for market events and cash flows that have occurred between the interim date and the end of the yearyear.
Derivative instruments are valued based upon valuation statements received from each derivative’s counterparty. Some of these contracts are not publicly traded.
The net pension plan assets, when categorized in accordance with this fair value hierarchy, are as follows. Investments valued using net asset value (NAV) as a practical expedient are presented to estimate the fair values asreconcile with total plan assets.

Assets that do not have readily available quoted prices in an active market require a higher degree ofmore judgment to value and have a higher degree of risk that the value that could have been realized upon sale as of the valuation date could be different from the reported value than assets with observable pricing inputs. It is possible that the full extent of market price, liquidity, currency, interest rate,increased risk. Approximately $330 million, or credit risks may not be fully factored into the fair values of our pension plan assets that use significant unobservable inputs. Approximately $4.7 billion, or 86.06.7 percent, of our pension plan assets were classified as Level 3 assets as of December 31, 2015.2018.
We estimate the fair value of pension plan assets based upon the information available during the year-end reporting process. In some cases, primarily private equity funds, the information available consists of net asset values as of an interim date, cash flows between the interim date and the end of the year, and market events. When the difference is significant, we revise the year-end estimated fair value of pension plan assets to incorporate year-end net asset values received after we have filed our annual report on Form 10-K. We increased the fair value of pension assets in the second quarter of 2015 by $57 million, or 1.0 percent.

ThisThe availability of observable market data is monitored to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. We evaluate the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total net assets available for benefits.

(1)  Service cost includes $2 million in 2014 and $4 million in 2013 for employees that were part of the Real Estate Divestiture. These charges are included in our results of discontinued operations. Curtailment and special termination benefits are related to involuntary terminations, due to restructuring activities, as well as the Real Estate Divestiture.
(2) During fourth quarter 2013, the decision was ratified to eliminate Company funding of the Post-Medicare Health Reimbursement Account (HRA) for certain salaried retirees after 2014. This change was communicated to affected retirees during January 2014. As a result, we recognized a pretax gain of $151 million in 2014 from this plan amendment.
Estimated Amortization from Cumulative Other Comprehensive Loss in 2016
Amortization of the net actuarial loss and prior service cost (credit) of our pension and postretirement benefit plans will affect our other comprehensive income in 2016. The net effect of the estimated amortization will be anincrease in net periodic benefit costs or a decrease in net periodic benefit credits in 2016.

Expected Pension Funding
Established funding standards govern the funding requirements for our qualified and registered pension plans. We fund the benefit payments of our nonqualified and nonregistered plans as benefit payments come due.
During 2016, based on estimated year-end asset values and projections of plan liabilities, we expect to:
be required to contribute approximately $16 million for our Canadian registered plan;
be required to contribute or make benefit payments for our Canadian nonregistered plans of $3 million; and
make benefit payments of approximately $19 million for our U.S. nonqualified pension plans.

We do not anticipate a contribution being required for our U.S. qualified pension plan for 2016.
Expected Postretirement Benefit Funding
Our retiree medical and life insurance plans are unfunded. Benefits for these plans are paid from our general assets as they come due. We expect to make benefit payments of $22 million for our U.S. and Canadian other postretirement benefit plans in 2016, including $7 million expected to be required to cover benefit payments under collectively bargained contractual obligations.

Expected Return on Plan Assets
We estimate the expected long-term return on assets for our:
our qualified, registered and registerednonregistered pension plans and
nonregistered plans.
Qualified and Registered Pension Plans.Plans Our expected
We assumed a long-term rate of return foron plan assets as of 8.0 percent for the year ended December 31, 2015, is comprised of: 2018.
As of the end of 2018, we have begun implementing a 7.2change in our asset strategy to an allocation that will more closely match the plan’s liability profile moving forward, resulting in a larger allocation of our assets into fixed income securities. With this change, we have determined that we will reduce our assumption of long-term rate of return on plan assets to 7.0 percent assumed return from direct investments and
a 1.7 percent assumed return from derivatives.for the year ended December 31, 2019.
Determining our expected return:
return requires a high degree of judgment,
uses our historicaljudgment. We consider actual pension fund performance over multiple years, and current and expected valuation levels in the global equity and credit markets. Historical fund returns are used as a base, and
places we place added weight on more recent pension plan asset performance.
Over the 31 years it has been in place, our U.S. pension trust investment strategy has achieved a 14.2 percent net compound annual return rate. The past 5 years, our net compounded annual return was 8.0 percent.Nonregistered Plans
Nonregistered plans. Canadian tax rules require that 50 percent of the assets for nonregistered plans go to a noninterest-bearing refundable tax account. As a result, the return we earn investing the other 50 percent is spread over 100 percent of the assets.
Our expected long-term annual rate of return on the equity portion of this portfolio — the portion we are allowed to invest and manage is 77.0 percent. We base that expected rate of return on:
This assumption is based on historical experience and
future return expectations.
Our The expected overall annual return on assets that fund our nonregistered plans is 3.5 percent.

The assumed health care cost trend rate can significantly influence projected postretirement benefit plan payments. Some of the benefits are defined dollar amounts and are unaffected by changes in health care costs. To determine the health care cost trend rate, we look at historical market experience, current environment and future expectations. The following table demonstrates the effect a 1one percent change in assumed health care cost trend rates would have with all other assumptions remaining constant.

Expected Pension Plan and Benefit Funding
Established funding standards govern the funding requirements for our qualified and registered pension plans. We fund the benefit payments of our nonqualified and nonregistered plans as benefit payments come due. We voluntarily contributed $300 million to our U.S. qualified pension plans during 2018, although there was no minimum required contribution for the year.
During 2018, we contributed $22 million for our Canadian registered plans, we made contributions and benefit payments of $2 million for our Canadian nonregistered pension plans and made benefit payments of $19 million for our nonqualified pension plans.
During 2019, based on estimated year-end asset values and projections of plan liabilities, we expect to:
be required to contribute approximately $17 million for our Canadian registered plan;
be required to contribute or make benefit payments for our Canadian nonregistered plans of $3 million; and
make benefit payments of approximately $16 million for our U.S. nonqualified pension plans.

We do not anticipate a contribution being required for our U.S. qualified pension plan for 2019.

UNION-ADMINISTERED MULTIEMPLOYER BENEFIT PLANS
We contribute to multiemployer defined benefit plans under the terms of collective-bargaining agreements thatagreements. These plans cover somea small number of our union-represented employees.employees and on an annual basis our contributions are immaterial.
The U.S.These plans are established to provide retirement income for eligible employees who meet certain age and service requirements at retirement. The benefits are generally based on:
a percentage of the employerhave different risks than single-employer plans. Our contributions paid into the plan on the eligible employee's behalf or
a formula considering an eligible employee's service, the total contributions paid on their behalf plus a benefit based on the value of an eligible employee's account.
The Canadian plan is a negotiated cost defined benefit plan. The plan is established to provide retirement income for members based on their number of years of service in the industry, and the benefit rate that applied to that service. 

The risks of participating in these multiemployer plans are different from single-employer plans in the following aspects:
Assets contributed to the multiemployer plan by one employer may be used to providefund benefits tofor employees of other participating employers.
If we choose to stop participating, we may be required to pay a withdrawal liability based on the underfunded status of the plan. If another participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.
If we choose to stop participating in some of the multiemployer plans, we may be required to pay those plans an amount based on the underfunded status of thebecome responsible for remaining plan referred to as a withdrawal liability.

NOTE 10: VARIABLE INTEREST ENTITIES
This note provides details about special-purpose entities (SPEs).
SPECIAL-PURPOSE ENTITIES
From 2002 through 2004, we sold certain nonstrategic timberlands in five separate transactions. We are the primary beneficiary and consolidate the assets and liabilities of certain monetization and buyer-sponsored SPEs involved in these transactions. We have an equity interest in the monetization SPEs, but no ownership interest in the buyer-sponsored SPEs. The following disclosures refer to assets of buyer-sponsored SPEs and liabilities of monetization SPEs. However, because these SPEs are distinct legal entities:
Assets of the SPEs are not available to satisfy our liabilities or obligations.
Liabilities of the SPEs are not our liabilities or obligations.
In 2013, we repaid a $162 million note and received $184 million related to one of our timber monetization SPEs undertaken in 2003. Net proceeds were $22 million.
Interest expense on SPE notes of:
$29 million in 2015,
$29 million in 2014 and
$29 million in 2013.
Interest income on SPE investments of:
$34 million in 2015,
$34 million in 2014 and
$34 million in 2013.
Sales proceeds paid to buyer-sponsored SPEs were invested in restricted financial investments with a balance of $615 million as of both December 31, 2015, and December 31, 2014. The weighted average interest rate was 5.5 percent during 2015 and 2014. Maturities of the financial investments at the end of 2015 were:
$253 million in 2019 and
$362 million in 2020.
The long-term notes of our monetization SPEs were $511 million as of both December 31, 2015, and December 31, 2014. The weighted average interest rate was 5.6 percent during 2015 and 2014. Maturities of the notes at the end of 2015 were:
$209 million in 2019 and
$302 million in 2020.
Financial investments consist of bank guarantees backed by bank notes for three of the SPE transactions. Interest earned from each financial investment is used to pay interest accrued on the corresponding SPE’s note. Any shortfall between interest earned and interest accrued reduces our equity in the monetization SPEs.
Upon dissolution of the SPEs and payment of all obligations of the entities, we would receive any net equity remaining in the monetization SPEs and would be required to report deferred tax gains on our income tax return. In the event that proceeds from the financial investments are insufficient to settle all of the liabilities of the SPEs, we are not obligated to contribute any funds to any of the SPEs. As of December 31, 2015, our net equity in the three SPEs was approximately $105 million and the deferred tax liability was estimated to be approximately $180 million.2016.

income approach — based on the discounted valueWe believe that our variable rate long-term debt and line of the future cash flows using market yields for the same type and comparable issues of debt.credit instruments have net carrying values that approximate their fair values with only insignificant differences.
The inputs to these valuations are based on market data obtained from independent sources or information derived principally from observable market data.
The difference between the fair value and the carrying value represents the theoretical net premium or discount we would pay or receive to retire all debt at the measurement date.
FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS
We believe that our other financial instruments, including cash and cash equivalents, short-term investments, mutual fund investments held in grantor trusts, receivables, and payables, have net carrying values that approximate their fair values with only insignificant differences. This is primarily due to:
to the short-term nature of these instruments
carrying short-term investments at expected net realizable value and
the allowance for doubtful accounts.

ENVIRONMENTAL MATTERS
Our environmental matters include:

Site Remediation
Under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) – commonly known as the Superfund and similar state laws, we:
are a party to various proceedings related to the cleanup of hazardous waste sites and
have been notified that we may be a potentially responsible party related to the cleanup of other hazardous waste sites for which proceedings have not yet been initiated.

We have received notification from the Environmental Protection Agency (the EPA) and have acknowledged that we are a potentially responsible party in a portion of the Kalamazoo River Superfund site in southwest Michigan. Our involvement in the remediation site is based on our former ownership of the Plainwell, Michigan mill located within the remediation site. In 2015 we received invitations fromSeveral other companies also have been deemed potentially responsible parties as past or present owners or operators of facilities within the Environmental Protection Agency (the “EPA”)site, or as arrangers under CERCLA.

We cooperated with other parties to negotiatejointly implement an administrative order issued by the EPA on consent for a contaminant removal action forApril 14, 2016, with respect to a portion of the site. Two other parties received the same invitations. All parties are in contact with the EPA as to the work required and the terms of any consent order. According to the EPA, this Superfund site encompasses 77 miles of the Kalamazoo River from a location east of the city of Kalamazoo to the river mouth at Lake Michigan. The EPA’s 2015 invitations concerncomprising a stretch of the river approximately 1.7 miles long that the EPA refersreferred to as the Otsego Township Dam Area. SeveralDuring third quarter 2018, implementation of this administrative order was completed.

In 2010, the company, along with others, was named as a defendant by Georgia-Pacific Consumer Products LP, Fort James Corporation and Georgia-Pacific LLC in an action seeking contribution under CERCLA for remediation costs relating to a certain area within the site. On March 29, 2018, the U.S. District Court issued an opinion and order assigning the company responsibility for 5 percent of approximately $50 million in past costs incurred by the plaintiffs. The remaining 95 percent of this pool of past costs incurred was allocated to the plaintiffs and other companies also operated upstream pulp mills. At this timedefendants.

The opinion and order, which is currently on appeal before the US Court of Appeals for the Sixth Circuit, does not establish allocation for future remediation costs, and accordingly, we are unable tomay incur additional costs in connection with future remediation tasks for other areas of the site.

We change our accrual to reflect:
new information on any site concerning implementation of remediation alternatives,
updates on prior cost estimates and new sites and
costs incurred to remediate sites.
Estimates. We believe it is reasonably possible, based on currently available information and analysis, that remediation costs for all identified sites may exceed our existing reserves by up to $116 million.$126 million.
This estimate, in which those additional costs may be incurred over several years, is the upper end of the range of reasonably possible additional costs. The estimate:
is much less certain than the estimates on which our accruals currently are based and
uses assumptions that are less favorable to us among the range of reasonably possible outcomes.
In estimating our current accruals and the possible range of additional future costs, we:
assumed we will not bear the entire cost of remediation of every site,
took into account the ability of other potentially responsible parties to participate and
considered each partys financial condition and probable contribution on a per-site basis.
We have not recorded any amounts for potential recoveries from insurance carriers.
Asset Retirement Obligations
We have obligations associated with the retirement of tangible long-lived assets consisting primarily of reforestation obligations related to forest management licenses in Canada and obligations to close and cap landfills. Some of our sites have asbestos containing materials. We have met our current legal obligation to identify and manage these materials. In situations where we cannot reasonably determine when asbestos containing materials might be removed from the sites, we have not recorded an accrual because the fair value of the obligation cannot be reasonably estimated. These obligations are recorded in "Accrued liabilities" and "Other liabilities" in our Consolidated Balance Sheet.

SHARE-BASED COMPENSATION RESULTING FROM OUR MERGER WITH PLUM CREEK
Replacement awards were granted as a result of the merger with Plum Creek. Eligible outstanding Plum Creek stock options, RSUs and deferred stock unit awards were converted into equivalent equity awards with respect to Weyerhaeuser Common Shares, after giving effect to the appropriate adjustments to reflect the consummation of the merger.

In total, we issued replacement awards consisting of 1,953 thousand stock options and 1,248 thousand RSUs. The replacement stock option awards were fully vested and had a total value of $5 million, which was included in the equity consideration issued with the merger. Qualifying terminations during 2016 resulted in accelerated vesting of 705 thousand of the replacement RSUs and recognition of $15 million of expense. The accelerated expense is included in the merger-related integration costs as described in Note 18: Charges for Integration and Restructuring, Closures and Asset Impairments.

We also assumed 289,910 value management awards (VMAs) through the merger with Plum Creek. Qualifying terminations during 2016 resulted in $6 million of expense recognized for VMAs. This accelerated expense is included in merger-related integration costs as described in Note 18: Charges for Integration and Restructuring, Closures and Asset Impairments.

HOW WE ACCOUNT FOR SHARE-BASED AWARDS
We:When accounting for share-based awards we:
use a fair-value-based measurement for share-based awards and
recognize the cost of share-based awards in our consolidated financial statements.

We recognize the cost of share-based awards in our Consolidated Statement of Operations over the required service period — generally the period from the date of the grant to the date when it is vested. Special situations include:
Awards that vest upon retirement — the required service period ends on the date an employee is eligible for retirement, including early retirement.
Awards that continue to vest following job elimination or the sale of a business — the required service period ends on the date the employment from the company is terminated.
In these special situations, compensation expense from share-based awards is recognized over a period that is shorter than the stated vesting period.
TAX BENEFITS OF SHARE-BASED AWARDS
Our total income tax benefit from share-based awards — as recognized in our Consolidated Statement of Operations — for the last three years was:
$85 million in 2015,2018,
$116 million in 2014,2017 and
$1012 million in 2013.2016.
The amounts2016 amount above containcontains a $2 million income tax benefit from share-based awards to employees that were part of the Real Estate Divestiture and areCellulose Fibers divestitures which is included in our results of discontinued operations. These amounts are:

When actual tax benefits realized exceed the tax benefits accrued for share-based awards, we realize an excess tax benefit. We report the excess tax benefit as financing cash inflows rather than operating cash inflows. We had excess tax benefits of:
$4 million in 2015,
$10 million in 2014 and
$13 million in 2013.
The amounts above contain excess tax benefits from share-based awards to employees that were part of the Real Estate Divestiture and are included in our results of discontinued operations. These amounts are:

TYPES OF SHARE-BASED COMPENSATION
Our share-based compensation is in the form of:
stock options,
restricted stock units,
performance share units,
stock appreciation rightsoptions and
deferred compensation stock equivalent units.
STOCK OPTIONS
Stock options entitle award recipients to purchase shares of our common stock at a fixed exercise price. We grant stock options with an exercise price equal to the market price of our stock on the date of the grant.
The Details
Our stock options generally:
vest over four years of continuous service and
must be exercised within 10 years of the grant-date.
The vesting and post-termination vesting terms for stock options granted in 2015, 2014 and 2013 were as follows:
vest ratably over four years;
vest or continue to vest in the event of death while employed or disability;
continue to vest upon retirement at an age of at least 62, but a portion of the grant is forfeited if retirement occurs before the one year anniversary of the grant;
continue to vest for one year in the event of involuntary termination when the retirement criteria has not been met; and
stop vesting for all other situations including early retirement prior to age 62.
Our Accounting
We use a Black-Scholes option valuation model to estimate the fair value of every stock option award on its grant-date.
In our estimates, we use:
historical data — for option exercise time and employee terminations;
a Monte-Carlo simulation — for how long we expect granted options to be outstanding; and
the U.S. Treasury yield curve — for the risk-free rate. We use a yield curve over a period matching the expected term of the grant.
The expected volatility in our valuation model is based on:
implied volatilities from traded options on our stock,
historical volatility of our stock and
other factors.

Share-based compensation expense for stock options is generally recognized over the vesting period. There are exceptions for stock options awarded to employees who:
are eligible for retirement;
will become eligible for retirement during the vesting period; or
whose employment is terminated during the vesting period due to job elimination or the sale of a business.

In these cases, we record the share-based compensation expense over a required service period that is less than the stated vesting period.

Our restricted stock unitsRSUs granted in 20152018, 20142017 and 20132016 generally:
vest ratably over four years;
immediately vest in the event of death while employed or disability;
continue to vest upon retirement at an age of at least 62, but a portion of the grant is forfeited if retirement occurs before the one year anniversary of the grant;
continue vesting for one year in the event of involuntary termination when the retirement has not been met; and
will be forfeited upon termination of employment in all other situations including early retirement prior to age 62.
Our Accounting
The fair value of our restricted stock unitsRSUs is the market price of our stock on the grant-date of the awards.
We generally record share-based compensation expense for restricted stock unitsRSUs over the four-year vesting period. Generally, for restricted stock unitsRSUs that continue to vest following the termination of employment, we record the share-based compensation expense over a required service period that is less than the stated vesting period.

Nonvested restricted stock unitsRSUs accrue dividends that are paid out when restricted stock unitsRSUs vest. Any restricted stock unitsRSUs forfeited will not receive dividends.
As restricted stock unitsRSUs vest, a portion of the shares awarded is withheld to cover employee taxes. As a result, the number of stock units vested and the number of common shares issued will differ.
PERFORMANCE SHARE UNITS
Through the 2013 Plan, we award performance share unitsPSUs — grants that entitle the holder to shares of our stock as the award vests.
The Details
The final number of shares awarded will range from 0 percent to 150 percent of each grant’s target, depending upon actual company performance.

For shares granted in 20152018 and 2017, the ultimate number of performance share unitsPSUs earned is based on two measures:

our relative total shareholder return (TSR) ranking measured against the S&P 500 over a three yearthree-year period and

our relative total shareholder return (TSR) ranking measured against the S&P 500 over a three-year period,
our relative TSR ranking measured against an industry peer group of companies over a three-year period and
achievement of Plum Creek merger cost synergy targets.

The vesting provisions for performance share unitsPSUs granted in 20152018, 2017, and 2016 were as follows:

vest 100 percent on the third anniversary of the grant date as long as the individual remains employed by the company;
fully vest in the event the participant dies or becomes disabled while employed;
continue to vest upon retirement at an age of at least 62, but a portion of the grant is forfeited if retirement occurs before the one year anniversary of the grant;
continue vesting for one year in the event of involuntary termination when the retirement criteria has not been met and the employee has met the second anniversary of the grant date; and
will be forfeited upon termination of employment in all other situations including early retirement prior to age 62.
For shares granted in 2014 and 2013 the ultimate number of performance share units earned is based on two measures:
Weyerhaeuser’s cash flow during the first year determined the initial number of units earned and
Weyerhaeuser’s relative total shareholder return (TSR) ranking in the S&P 500 during the first two years is used to adjust the initial number of units earned up or down by 20 percent.
At the end of the two-year performance period and over a further two-year vesting period, performance share units would be paid in shares of our stock. Performance share units granted and that are earned vest as follows:
vest 50 percent, 25 percent and 25 percent on the second, third and fourth anniversaries of the grant-date, respectively, as long as the individual remains employed by the company;
fully vest in the event the participant dies or becomes disabled while employed;
continue to vest upon retirement at an age of at least 62, but a portion of the grant is forfeited if retirement occurs before the one year anniversary of the grant;
continue vesting for one year in the event of involuntary termination when the retirement has not been met; and
will be forfeited upon termination of employment in all other situations including early retirement prior to age 62.
Our Accounting
Since the award containsawards contain a market condition, the effect of the market condition is reflected in the grant-date fair value which is estimated using a Monte Carlo simulation model. This model estimates the TSR ranking of the company over the performance period. Compensation expense is based on the estimated probable number of earned awards and recognized over the vesting period on an accelerated basis. Generally, compensation expense would be reversed if the performance condition is not met unless the requisite service period has been achieved.

For 2014 grants, the company exceeded the cash flow target, resulting in an initial number of shares earned equal to 114 percent of target. Because the company's two-year TSR ranking was between the 25th and 50th percentile, the initial number of performance shares granted decreased 11 percent.
For 2013 grants, the company exceeded the cash flow target, resulting in an initial number of shares earned equal to 150 percent of target.

STOCK APPRECIATION RIGHTS
Through the Plan, we grant cash-settled stock appreciation rights as part of certain compensation awards.
The DetailsOPTIONS
Stock appreciation rights are similaroptions entitle award recipients to purchase shares of our common stock options. Employees benefit whenat a fixed exercise price. During 2018 and 2017, we did not grant any stock option awards. When granted in prior years, however, we granted stock options with an exercise price equal to the market price of our stock is higher on the exercise date than it was on the date of the grant.
The Details
Our stock appreciation rights were granted. The differences are thatoptions generally:
vest over four years of continuous service,
must be exercised within 10 years of the employee:
receives the benefit as a cash awardgrant-date and
does not purchase the underlying stock.
The vesting conditions and exceptions are the same as for 10-year stock options. Details are in the Stock Options section earlier in this note.
Stock appreciation rights are generally issued to employees outside of the U.S.
Our Accounting
We use a Black-Scholes option-valuationoption valuation model to estimate the fair value of aevery stock appreciation rightoption award on its grant-date and every subsequent reporting date that the right is outstanding. Stock appreciation rights are liability-classified awards and the fair value is remeasured at every reporting date.grant-date.

DEFERRED COMPENSATION STOCK EQUIVALENT UNITS
Certain employees and our board of directors may defer compensation into stock-equivalent units.
The Details
The plan2013 Plan works differently for employees and directors.
Eligible employees:
may choose to defer all or part of their bonus into stock-equivalent units;
may choose to defer part of their salary, except for executive officers; and
receive a 15 percent premium if the deferral is for at least five years.
Our directors:
receive a portion of their annual retainer fee in the form of restricted stock units,RSUs, which vest over one year and may be deferred into stock-equivalent units;
may choose to defer some or all of the remainder of their annual retainer fee into stock-equivalent units; and
do not receive a premium for their deferrals.
Employees and directors also choose when the deferrals will be paid out although no deferrals may be paid until after the separation from service of the employee or director.
Our Accounting
We settle all deferred compensation accounts in cash for our employees. Our directors receive shares of common stock as payment for stock-equivalent units. In addition, we credit all stock-equivalent accounts with dividend equivalents. The number of common shares to be issued in the future to directors is 651,729.639 thousand.
Stock-equivalent units are:
liability-classified awards and
re-measured to fair value at every reporting date.
The fair value of a stock-equivalent unit is equal to the market price of our stock.
Activity
The number of stock-equivalent units outstanding in our deferred compensation accounts was:were:

The Impairment of Long-Lived Assets and Goodwill sectionssection of Note 1: Summary of Significant Accounting Policies provideprovides details about how we account for these impairments. Additional information can also be found in our Critical Accounting Policies.
Long-Lived Assets
Our long-lived asset impairments were primarily related to the following:
2017 — In second quarter 2017, we recognized an impairment charge to the timberlands and manufacturing assets of our Uruguayan operations. On June 2, 2017, our Board of Directors approved an agreement to sell all of the Company's equity in the Uruguayan operations to a consortium led by BTG Pactual's Timberland Investment Group (TIG). As a result of this agreement, the related assets met the criteria to be classified as held for sale at June 30, 2017. This designation required us to record the related assets at fair value, less an amount of estimated selling costs, and thus recognize a $147 million noncash pretax impairment charge. This amount was recorded in the Timberlands segment. The fair value of the related assets was primarily based on the agreed upon cash purchase price of $403 million. On September 1, 2017, we announced the completion of the sale. Refer to Note 4: Discontinued Operations and Other Divestitures for further details on the Uruguayan operations sale.
2015 — WeAdditionally, in September 2017, we recognized an impairment charge of $13$6 million related to a nonstrategic asset held in Unallocated Items.our Wood Products segment. The fair value of the asset was determined using significant unobservable inputs (Level 3) based onthe value indicated in a discounted cash flow model. The asset was subsequently sold for no gain during 2015.purchase and sale agreement.
20132016charges include:
– $356We recognized a $15 million impairment charge in Real Estate & ENR which represents the fair value less direct selling costs of certain development projects that we planned to sell that had a book value greater than fair value. The fair values of the Coyote Springs Property. Under the terms of the TRI Pointe transaction, certain assets and liabilities of WRECO and its subsidiariesprojects were excluded from the transaction and retained by Weyerhaeuser, including assets and liabilities relating to the Coyote Springs Property. During fourth quarter 2013, following the announcement of the TRI Pointe transaction, WRECO and Weyerhaeuser began exploring strategic alternatives for the Coyote Springs Property and determined that Weyerhaeuser’s strategy for development of the Coyote Springs Property will likely differ from WRECO’s current development plan. WRECO’s development plan was long-term in nature with development and net cash flows covering at least 15-20 years. The undiscounted cash flows for the Coyote Springs Property under the WRECO development plan remained above the carrying value of the property. Weyerhaeuser Company’s strategy was to cease holding the Coyote Springs Property for development, and we initiated activities to market the assets to potential third-party buyers. The undiscounted cash flows under the Weyerhaeuser Company asset sale strategy were below the carrying value of the property. Consequently, we recorded a noncash charge of $356 million in fourth quarter 2013 for the impairment of the Coyote Springs Property in Unallocated Items. The fair value of the property was primarily based on an independent appraisal that was determined using both other observable inputs (Level 2) related to other market transactions and significant unobservable inputs (Level 3) such as the timing and amounts of future cash flows related to the development of the property, timing and amounts of proceeds from acreage sales, access to water for use on the property and discount rates applicable to the future cash flows.

WEYERHAEUSER COMPANY >We recorded insurance recoveries of $25 million and product remediation charges of $25 million for the year ended December 31, 2018. During the year ended December 31, 2017, we recorded $290 million to accrue for expected costs associated with the remediation.

our ongoing IRS tax matter.
Income taxes related to discontinued operations are discussed inNote 4: Discontinued Operations and Other Divestitures.
The Income Taxes section of Note 3: Discontinued Operations1: Summary of Significant Accounting Policies provides details about how we account for our income taxes.
Tax Legislation
On December 22, 2017, H.R. 1, commonly known as the Tax Cuts and Jobs Act (the "Tax Act"), was enacted. The Tax Act contains significant changes to corporate taxation, including the reduction of the corporate tax rate from 35 percent to 21 percent. As a result of the reduction in the corporate tax rate, we revalued our deferred tax assets and liabilities and recorded a tax expense of $74 million during 2017, which reduced our net deferred tax asset. We were not required to pay a repatriation tax due to the fact that we had no foreign undistributed earnings at December 31, 2017.
The most significant effects of the Tax Act provisions for 2018 include a reduction to our overall estimated annual effective tax rate primarily due to the reduced corporate tax rate, and new limitations on certain business deductions.
During first quarter 2018, we adopted ASU 2018-02 which allowed for the reclassification of certain income tax effects related to the Tax Act between "Accumulated other comprehensive loss” and “Retained earnings”. Refer to Note 1: Summary of Significant Accounting Policies for further details on this ASU and the related effect on our financial statements.
Pension Contribution Tax Adjustment
At the end of 2017, we revalued our deferred tax assets (including pension) to the 2018 federal tax rate of 21 percent, as a result of the Tax Act, as discussed above. During third quarter 2018, we announced actions intended to reduce the liabilities of our U.S. qualified pension plan while maintaining the plan’s current funded status and made a decision to contribute $300 million to our U.S. qualified pension plan (refer to Note 10: Pension and Other Postretirement Benefit Plans). We were able to deduct this contribution on our 2017 U.S. federal tax return at the 2017 federal tax rate of 35 percent. This resulted in an incremental $41 million tax benefit for the portion attributable to our TRSs during third quarter 2018.

Our valuation allowance on our deferred tax assets was $72$61 million as of at the end of 2015, primarily2018, related to foreign andstate credits, state net operating losses and state and provincialpassive foreign tax credits.
Reinvestment of Undistributed Earnings
The balanceWe have historically asserted it is our intent to reinvest the earnings of our foreign subsidiaries. In fourth quarter 2018, we changed our position regarding the earnings of our Canadian subsidiary. Our change in assertion was based on the company’s review of global cash management and planned capital deployment, taking into consideration the effects of the Tax Act. As of 2018, our assertion is to permanently reinvest approximately 10 percent of our Canadian earnings. We have no other foreign subsidiaries with undistributed earnings was approximately $34 million at the end of 2015, all of which is permanently reinvested; therefore, it is not subject to U.S. income tax. Generally, such earnings become subject to U.S. tax upon the remittance of dividends and under certain other circumstances. It is not practicable to estimate the amount ofearnings. Accordingly, deferred tax liabilitytaxes have been provided primarily related to investments in our foreign subsidiaries.
HOW WE ACCOUNT FOR INCOME TAXES
The Income Taxes section of Note 1: Summary of Significant Accounting Policies provides details about how we account for our income taxes.Canadian withholding taxes associated with Canadian earnings no longer considered permanently reinvested.

RESOLUTION OF IRS MATTER

In connection with the merger with Plum Creek, we acquired equity interests in Southern Diversified Timber, LLC, a timberland joint venture (Timberland Venture) with an affiliate of Campbell Global LLC (TCG Member). On August 31, 2016, the Timberland Venture redeemed TCG Member's interest and became a fully consolidated, wholly-owned subsidiary of Weyerhaeuser.
WEYERHAEUSER COMPANY > 2015 ANNUAL REPORT AND FORM 10-K104We received a Notice of Final Partnership Administrative Adjustment (FPAA), dated July 20, 2016, from the Internal Revenue Service (IRS) in regard to Plum Creek's 2008 U.S. federal income tax treatment of the transaction forming the Timberland Venture. The IRS asserted that the transfer of the timberlands to the Timberland Venture was a taxable transaction to Plum Creek at the time of the transfer rather than a nontaxable capital contribution. We subsequently filed a petition in the U.S. Tax Court to contest this adjustment.
On February 8, 2019, we entered into a closing agreement with the IRS to settle this dispute. Under the terms of the agreement, the company paid approximately $21 million of corporate tax. This amount was recorded as tax expense in fourth quarter 2018. No interest or penalties will be assessed. The parties have filed a stipulated decision with the U.S. Tax Court, pursuant to which the Court will officially close the matter.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The
To the Shareholders and Board of Directors and Shareholders
Weyerhaeuser Company:

Opinion on Internal Control Over Financial Reporting
We have audited Weyerhaeuser Company’sCompany and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2015,2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) . WeyerhaeuserCommission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2018 and 2017, the related consolidated statements of operations, comprehensive income, changes in equity, and cash flows for each of the years in the three-year period ended December 31, 2018, and the related notes (collectively, the consolidated financial statements), and our report dated February 15, 2019 expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
The Company’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, included in the accompanying Management’s Report on Internal Control Overover Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. 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 of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
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, Weyerhaeuser Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Weyerhaeuser Company and subsidiaries as of December 31, 2015 and 2014, and the related consolidated statements of operations, comprehensive income, cash flows, and changes in equity for each of the years in the three-year period ended December 31, 2015, and our report dated February 17, 2016 expressed an unqualified opinion on those consolidated financial statements.
