PART I

ITEM 1. Business

General

Our company, founded in 1973 and headquartered in Nashville, Tennessee, is a leading manufacturer of building products. As of December 31, 2013, we had approximately 4,200 employees. We currently own 21 modern, strategically located facilities in the U.S. and Canada, two facilities in Chile and one facility in Brazil. We also operate facilities through a joint venture, for which we are the exclusive provider of product distribution for North America. Our focus is on delivering innovative, high-quality commodity and specialty building products to retail, wholesale, home building and industrial customers. Our products are used primarily in new home construction, repair and remodeling, and manufactured housing.

In May 2013, we increased our ownership of an OSB facility in British Columbia, Canada with an annual production capacity of 820 million square feet to 100% by purchasing Canfor Corporation’s 50% interest in our former joint venture. In August 2013, we sold our moulding operations and, in December 2013, we sold our 50% interest in U.S. GreenFiber, LLC, a former joint venture with Casella Waste Management Systems, Inc. that produced cellulose insulation.

Business Segments

We operate in four segments: North America Oriented Strand Board (OSB); Siding; Engineered Wood Products (EWP); and South America. In general, our businesses are affected by the level of housing starts; the level of home repairs; changes in industry capacity; changes in the prices we pay for raw materials and energy; changes in foreign exchange rates (primarily the Canadian dollar, Chilean Peso and Brazilian Real); and the availability and cost of financing and changes in other operating costs.

OSB

Our OSB segment manufactures and distributes OSB structural panel products.

OSB is an innovative, affordable and environmentally smart product made from wood strands arranged in layers and bonded with resin. OSB serves many of the same uses as plywood, including roof decking, sidewall sheathing and floor underlayment, but can be produced at a significantly lower cost. It is estimated for 2013 that OSB accounted for approximately 61% of the structural panel consumption in North America with plywood accounting for the remainder. We estimate that the overall North American structural panel market (based upon 2013 housing starts) was 28.3 billion square feet with the OSB market comprising an estimated 17.3 billion square feet of this market. Based upon our production in 2013 of 4.1 billion square feet (including OSB produced in our siding segment), we estimate that we account for 24% of the North American OSB market and 14% of the overall North American structural panel market. We believe we have the largest installed capacity and are one of the most efficient producers of OSB in North America.

Siding

Our siding offerings fall into two categories: SmartSide^® siding products and related accessories; and CanExel siding and accessory products. Our SmartSide^® products consist of a full line of wood-based sidings, trim, soffit and fascia. These products have quality and performance characteristics similar to solid wood at more attractive prices due to lower raw material and production costs. Our CanExel siding and accessory product offerings include a number of pre-finished lap and trim products in a variety of patterns and textures.

Additionally, minor amounts of commodity OSB are produced and sold in this segment.

Engineered Wood Products

Our Engineered Wood Products (EWP) segment manufactures and distributes laminated veneer lumber (LVL), I-Joists, laminated strand lumber (LSL) and other related products. This segment also includes the sale of I-Joist produced by our joint venture with Resolute Forest Products (formerly AbitibiBowater) and LVL sold under a contract manufacturing arrangement. We believe that in North America we are one of the top three producers

2

(including our joint venture production) of I-Joists, LVL and LSL. A plywood mill associated with our LVL operations in British Columbia is also included in this segment.

We believe that our engineered I-joists, which are used primarily in residential and commercial flooring and roofing systems and other structural applications, are stronger, lighter and straighter than conventional lumber joists. Our LVL and LSL are high-grade, value-added structural products used in applications where extra strength and quality is required, such as headers and beams.

South America

Our South American segment manufactures and distributes OSB and siding products in South America and certain export markets. This segment also distributes and sells related products to augment the transition to wood frame construction. We believe we are the only producer of OSB in South America.

Other Products

Our other products category includes our remaining timber and timberlands, and other minor products, services and closed operations. Prior to their disposition during 2013, this category also included our interest in a joint venture that produced cellulose insulation and our former moulding operations.

Sales, Marketing and Distribution

Our sales and marketing efforts are primarily focused on traditional two-step distribution, professional building products dealers, home centers, third-party wholesale buying groups and other retailers. The wholesale distribution channel includes a variety of specialized and broad-line wholesale distributors and dealers focused primarily on the supply of products for use by professional builders and contractors. The retail distribution channel includes large retail chains catering to the do-it-yourself (DIY) and repair and remodeling markets as well as smaller independent retailers.

Customers

We seek to maintain a broad customer base and a balanced approach to national distribution through both wholesale and retail channels. In 2013, our top ten customers accounted for approximately 44% of our sales. Because a significant portion of our sales are from OSB, a commodity product sold primarily on the basis of price and availability, we are not dependent on any one customer. Our principal customers include the following:

• Wholesale distribution companies, which supply building materials to retailers on a regional, state or local basis;

• Two-step distributors, who provide building materials to smaller retailers, contractors and others;

• Building materials professional dealers, that specialize in sales to professional builders, remodeling firms and trade contractors that are involved in residential home construction and light commercial building;

• Retail home centers, that provide access to consumer markets with a broad selection of home improvement materials and increasingly serve professional builders, remodelers and trade contractors; and

• Manufactured housing and shed producers, who design, construct and distribute prefabricated residential and light commercial structures, including fully manufactured, modular and panelized structures, for consumer and professional markets.

Seasonality

Our business is subject to seasonal variances, with demand for many of our products tending to be greater during the building season, which generally occurs in the second and third quarters in North America and the fourth and first quarters in South America. From time to time, we engage in promotional activities designed to stimulate demand for our products, such as reducing our selling prices and providing extended payment terms, particularly at times when demand is otherwise relatively soft. We do this in an effort to better balance our inventory levels with

3

demand, manage the logistics of our product shipments, allow our production facilities to run efficiently, be competitive, and/or obtain initial orders from customers.

Competitors / Competition

The building products industry is highly competitive. We compete internationally with several thousand forest and building products firms, ranging from very large, fully integrated firms to smaller enterprises that may manufacture only one or a few items. We also compete less directly with firms that manufacture substitutes for wood building products. Some competitors have substantially greater financial and other resources than we do that could, in some instances, give them a competitive advantage over us.

In terms of our commodity OSB, we compete based upon price, quality and availability of products. In terms of our specialty products, including EWP, siding and various value added OSB products, we compete based upon price, quality, and availability of products as well as performance features offered.

Raw Materials

Wood fiber is the primary raw material used in most of our operations, and the primary source of wood fiber is timber. The primary end-markets for timber harvested in the U.S. are manufacturers who supply: (1) the housing market, where it is used in the construction of new housing and the repair and remodeling of existing housing; (2) the pulp and paper market; (3) commercial and industrial markets; (4) export markets; and (5) emerging biomass energy production markets. The supply of timber is limited by access to timber and by the availability of timberlands. The availability of timberlands, in turn, is limited by several factors, including forest management policies, alternate uses of land, and loss to urban or suburban real estate development.

In Canada, we harvest enough timber annually under long-term harvest rights with various Canadian governments and other third parties to support our Canadian production facilities.

We purchase approximately 71% of our wood fiber requirements on the open market, through either private cutting contracts or purchased wood arrangements. Our remaining wood fiber requirements (29%) are fulfilled through government contracts, principally in Canada. Because wood fiber is subject to commodity pricing, the cost of various types of timber that we purchase in the market has at times fluctuated greatly due to weather, governmental, economic or other industry conditions. However, our mills are generally located in areas that are in close proximity to large and diverse supplies of timber. Our mills generally have the ability to procure wood fiber at competitive prices from third-party sources.

In addition to wood fiber, we use a significant quantity of various resins in our manufacturing processes. Resin product costs are influenced by changes in the prices of raw materials used to produce resin, primarily petroleum products, as well as competing demand for resin products. Currently, we purchase the majority of our resin from three major suppliers and believe our relationships with those suppliers to be good. However there can be no assurance that pricing or availability of resins will not be impacted based upon competing demand.

While a portion of our energy requirements are generated at our plants through the conversion of wood waste, we also purchase substantial amounts of energy in our operations, primarily electricity and natural gas. Energy prices have experienced significant volatility in recent years, particularly in deregulated markets. We attempt to mitigate our exposure to energy price changes through the selective use of long-term supply agreements.

Environmental Compliance

Our operations are subject to many environmental laws and regulations governing, among other things, discharges of pollutants and other emissions on or into land, water and air, the disposal of hazardous substances or other contaminants, the remediation of contamination and the restoration and reforestation of timberlands. In addition, certain environmental laws and regulations impose liability and responsibility on present and former owners, operators or users of facilities and sites for contamination at such facilities and sites without regard to

4

causation or knowledge of contamination. Compliance with environmental laws and regulations can significantly increase the costs of our operations and otherwise result in significant costs and expenses. In some cases, plant closures can result in more onerous compliance requirements becoming applicable to a facility or a site. Violations of environmental laws and regulations can subject us to additional costs and expenses, including defense costs and expenses and civil and criminal penalties. We cannot assure you that the environmental laws and regulations to which we are subject will not become more stringent, or be more stringently implemented or enforced, in the future.

During 2012, the U.S. Environmental Protection Agency (EPA) finalized the Clean Air Act pollution standards. We estimate that we will be required to make capital expenditures in the range of $3 million to $13 million over the next six years to comply with such standards.

Our policy is to comply fully with all applicable environmental laws and regulations. We devote significant management attention to achieving full compliance. In addition, from time to time, we undertake construction projects for environmental control equipment or incur other environmental costs that extend an asset’s useful life, improve its efficiency or improve the marketability of certain properties.

Additional information concerning environmental matters is set forth under item 3, Legal Proceedings, and in Note 18 of the Notes to the consolidated financial statements included in item 8 of this report.

Employees

We employ approximately 4,200 people, about 575 of whom are members of unions, primarily in Canada, Chile and Brazil. We consider our relationship with our employees generally to be good. While we do not currently anticipate any work stoppage, there can be no assurance that work stoppages will not occur.

ITEM 1A. Risk Factors

You should be aware that the occurrence of any of the events described in this Risk Factors section and elsewhere in this report or in any other of our filings with the SEC could have a material adverse effect on our business, financial position, results of operations and cash flows. In evaluating us, you should consider carefully, among other things, the risks described below and the matters described in “About Forward-Looking Statements.”

Cyclical industry conditions and commodity pricing have and may continue to adversely affect our financial condition and results of operations. Our operating results reflect the general cyclical pattern of the building products industry. Demand for our products correlates to a significant degree to the level of residential construction activity in North America, which historically has been characterized by significant cyclicality. This cyclicality is influenced by a number of factors, including the supply of new and existing homes on the market, the level of unemployment, longer-term interest rates, and mortgage foreclosure rates. The cyclicality is also influenced by the availability of mortgage financing, which is currently more restrictive than normal and which could be adversely affected by the implementation of one or more proposals to eliminate or reduce the mortgage market roles of or levels of support for government-sponsored enterprises such as Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation. A significant increase in longer-term interest rates, a prolonged decline in the availability of mortgage financing, or the occurrence of other events that reduce levels of residential construction activity could have a material adverse effect on our financial condition, results of operations and cash flows. Our primary product, OSB, and a significant portion of our raw materials are globally traded commodity products. In addition, our products are subject to competition from manufacturers worldwide. Historical prices for our products have been volatile, and we, like other participants in the building products industry, have limited influence over the timing and extent of price changes for our products. Product pricing is significantly affected by the relationship between supply and demand in the building products industry. Product supply is influenced primarily by fluctuations in available manufacturing capacity. Demand is affected by the state of the economy in general and a variety of other factors, including the level of new residential construction activity and home repair and remodeling activity, changes in the availability and cost of mortgage financing and weather conditions. We are not able to predict with certainty market conditions and selling prices for our products. In this competitive environment with so many variables for which we do not control, we cannot assure you that prices for our products will not decline from current levels. A prolonged and severe weakness in the markets for one or more of our principal products, particularly OSB, could seriously harm our financial condition and results of operations and our ability to satisfy our cash requirements, including the payment of interest and principal on our debt.

We have a high degree of product concentration. OSB accounted for about 58%, 57% and 48% of our North American sales in 2013, 2012 and 2011 and we expect OSB sales to continue to account for a substantial portion of our revenues and profits in the future. Concentration of our business in the OSB market further increases our sensitivity to commodity pricing and price volatility. In this competitive environment with so many variables for which we do not control, we cannot assure you that pricing for OSB or our other products will not decline from current levels.

Intense competition in the building products industry could prevent us from increasing or sustaining our net sales and profitability. The markets for our products are highly competitive. Our competitors range from very large, fully integrated forest and building products firms to smaller firms that may manufacture only one or a few types of products. We also compete less directly with firms that manufacture substitutes for wood building products. Many of our competitors have greater financial and other resources than we do, and certain of the mills operated by our competitors may be lower-cost producers than the mills operated by us.

Our results of operations may be harmed by potential shortages of raw materials and increases in raw material costs. The most significant raw material used in our operations is wood fiber. We currently obtain about 71% of our wood fiber requirements in the open market. Wood fiber is subject to commodity pricing, which fluctuates on the basis of market factors over which we have no control. In addition, the cost of various types of wood fiber that we purchase in the market has at times fluctuated greatly because of governmental, economic or industry conditions, and may be affected by increased demand resulting from initiatives to increase the use of

7

biomass materials in the production of heat, power, biobased products and biofuels. In addition to wood fiber, we also use a significant quantity of various resins in our manufacturing processes. Resin product costs are influenced by changes in the prices or availability of raw materials used to produce resins, primarily petroleum products, as well as demand for and availability of resin products. Selling prices of our products have not always increased in response to raw material cost increases. We are unable to determine to what extent, if any, we will be able to pass any future raw material cost increases through to our customers through product price increases. Our inability to pass increased costs through to our customers could have a material adverse effect on our financial condition, results of operations and cash flows.

Many of the Canadian forestlands from which we obtain wood fiber also are subject to the constitutionally protected treaty or common-law rights of the aboriginal peoples of Canada. Most of British Columbia is not covered by treaties and, as a result, the claims of British Columbia’s aboriginal peoples relating to forest resources are largely unresolved, although many aboriginal groups are actively engaged in treaty discussions with the governments of British Columbia and Canada. Final or interim resolution of claims brought by aboriginal groups are expected to result in additional restrictions on the sale or harvest of timber and may increase operating costs and affect timber supply and prices in Canada.

We depend on our senior management team and other key employees, and significant attrition within our management team could adversely affect our business. Our success depends in part on our ability to attract, retain and motivate senior management and other key employees. Achieving this objective may be difficult due to many factors, including fluctuations in global economic and industry conditions, competitors’ hiring practices, cost reduction activities, and the effectiveness of our compensation programs. Competition for qualified personnel can be very intense. We must continue to recruit, retain and motivate senior management and other key employees sufficient to maintain our current business and support our future projects. A loss of any such personnel, or the inability to recruit and retain qualified personnel in the future, could have an adverse effect on our business, financial condition and results of operations.

Our operations require substantial capital. Capital expenditures for expansion or replacement of existing facilities or equipment or to comply with future changes in environmental laws and regulations may be substantial. Although we maintain our production equipment with regular periodic and scheduled maintenance, we cannot assure you that key pieces of equipment in our various production processes will not need to be repaired or replaced or that we will not incur significant additional costs associated with environmental compliance. The costs of repairing or replacing such equipment and the associated downtime of the affected production line could have a material adverse effect on our financial condition, results of operations and cash flow. If for any reason we are unable to provide for our operating needs, capital expenditures and other cash requirements on economic terms, we could experience a material adverse effect on our business, financial condition, results of operations and cash flows.

Our pension and health care costs are subject to numerous factors which could cause these costs to change. We have defined benefit pension plans covering substantially all U.S. and Canadian employees. We provide retiree health care benefits to certain of our U.S. salaried and certain hourly employees. Our pension costs are dependent upon numerous pension plan provisions that are subject to interpretations and factors resulting from actual plan experience and assumptions of future experience. Pension plan assets are primarily made up of equity and fixed income investments. Fluctuations in actual equity market returns; changes in general interest rates and changes in the number of retirees may result in increased pension costs in future periods. Likewise, changes in assumptions regarding current discount rates and expected rates of return on plan assets could also change pension and health care costs. We are subject to market risk on pension plan assets as well as discount rates on long-term obligations. Significant adverse changes in the factors affecting our pension and health care costs could adversely affect our cash flows, financial condition and results of operations.

Our pension plans are currently underfunded, and over time we may be required to make cash payments to the plans, reducing the cash available for our business. We record a liability associated with our pension plans equal to the excess of the benefit obligation over the fair value of plan assets. The benefit liability recorded under the provisions of Accounting Standards Codification (ASC) 715, “Compensation—Retirement Benefits,” at December 31, 2013 was $51.8 million. Although we expect to contribute $2.0 million to $5.0 million to our plans in

8

2014, we continually reassess the amount and timing of any discretionary contributions. Over the next several years we may make significant contributions to the plans. The amount of such contributions will depend upon a number of factors, principally the actual earnings and changes in values of plan assets and changes in interest rates.

We depend on third parties for transportation services and increases in costs and the availability of transportation could materially and adversely affect our business and operations. Our business depends on the transportation of a large number of products, both domestically and internationally. We rely primarily on third parties for transportation of the products we manufacture and/or distribute as well as for delivery of our raw materials. In particular, a significant portion of the goods we manufacture and raw materials we use are transported by railroad or trucks, which are highly regulated. If any of our third-party transportation providers were to fail to deliver the goods we manufacture or distribute in a timely manner, we may be unable to sell those products at full value or at all. Similarly, if any of these providers were to fail to deliver raw materials to us in a timely manner, we may be unable to manufacture our products in response to customer demand. In addition, if any of these third parties were to cease operations or cease doing business with us, we may be unable to replace them at reasonable cost. Any failure of a third-party transportation provider to deliver raw materials or finished products in a timely manner could harm our reputation, negatively affect our customer relationships and have a material adverse effect on our financial condition and results of operations. In addition, an increase in transportation rates or fuel surcharges could materially and adversely affect our sales and profitability.

We are subject to significant environmental regulation and environmental compliance expenditures and liabilities. Our businesses are subject to many environmental laws and regulations, particularly with respect to discharges of pollutants and other emissions on or into land, water and air, and the disposal and remediation of hazardous substances or other contaminants and the restoration and reforestation of timberlands. Compliance with these laws and regulations is a significant factor in our business. We have incurred and expect to continue to incur significant expenditures to comply with applicable environmental laws and regulations. Moreover, some or all of the environmental laws and regulations to which we are subject could become more stringent in the future. Our failure to comply with applicable environmental laws and regulations and permit requirements could result in civil or criminal fines or penalties or enforcement actions, including regulatory or judicial orders enjoining or curtailing operations or requiring corrective measures, installation of pollution control equipment or remedial actions.

Some environmental laws and regulations impose liability and responsibility on present and former owners, operators or users of facilities and sites for contamination at such facilities and sites without regard to causation or knowledge of contamination. In addition, we occasionally evaluate various alternatives with respect to our facilities, including possible dispositions or closures. Investigations undertaken in connection with these activities may lead to discoveries of contamination that must be remediated, and closures of facilities may trigger compliance requirements that are not applicable to operating facilities. Consequently, we cannot assure you that existing or future circumstances or developments with respect to contamination will not require significant expenditures by us.

We are involved in various environmental matters, product liability and other legal proceedings. The outcome of these matters and proceedings and the magnitude of related costs and liabilities are subject to uncertainties. The conduct of our business involves the use of hazardous substances and the generation of contaminants and pollutants. In addition, the end-users of many of our products are members of the general public. We currently are or from time to time in the future may be involved in a number of environmental matters and legal proceedings, including legal proceedings involving anti-trust, warranty or non-warranty product liability claims, negligence and other claims, including claims for wrongful death, personal injury and property damage alleged to have arisen out of the use by others of our or our predecessors’ products or the release by us or our predecessors of hazardous substances. Environmental matters and legal matters and proceedings, including class action settlements relating to certain of our products, have in the past caused and in the future may cause us to incur substantial costs. We have established contingency reserves in our consolidated financial statements with respect to the estimated costs of existing environmental matters and legal proceedings to the extent that our management has determined that such costs are both probable and reasonably estimable as to amount. However, such reserves are based upon various estimates and assumptions relating to future events and circumstances, all of which are subject to inherent uncertainties. We regularly monitor our estimated exposure to environmental and litigation loss contingencies and, as additional information becomes known, may change our estimates significantly. However, no estimate of the range of any such

9

change can be made at this time. We may incur costs in respect of existing and future environmental matters and legal proceedings as to which no contingency reserves have been established. We cannot assure you that we will have sufficient resources available to satisfy the related costs and expenses associated with these matters and proceedings.

Settlements of tax exposures may exceed the amounts we have established for known estimated tax exposures. We maintain reserves for known estimated tax exposures in federal, state and international jurisdictions and uncertain tax positions. Significant income tax exposures may include potential challenges to intercompany pricing and loans, the treatment of financing, acquisition and disposition transactions, the use of hybrid entities and other matters. These exposures are settled primarily through the closure of audits with the taxing jurisdictions and, on occasion, through the judicial process, either of which may produce a result inconsistent with past estimates. We believe that we have established appropriate reserves for estimated exposures; however, if actual results differ materially from our estimates we could experience a material adverse effect on our financial condition, results of operations and cash flows. In addition, our deferred tax liabilities include substantial amounts related to installment sales of timber lands in 1998 and 2003 for which we have previously monetized most of the installment receivable. As a result of these monetizations, we will be required to fund these liabilities from sources other than such installments, potentially including such tax loss and credit carryovers as may then be available.

Fluctuations in foreign currency exchange rates could result in currency exchange losses and reductions in stockholder’s equity. A significant portion of our operations are conducted through foreign subsidiaries. The functional currency for our Canadian subsidiary is the U.S. dollar. The financial statements of this foreign subsidiary are remeasured into U.S. dollars using the historical exchange rate for property, plant and equipment, timber and timberlands, equity and certain other non-monetary assets and liabilities and related depreciation and amortization on these assets and liabilities. These transaction and translation gains or losses are recorded in foreign exchange gains (losses) in the income statement. The functional currency of our Chilean subsidiary is the Chilean peso and the functional currency of our Brazililian subsidiary is the Brazilian real. Translation adjustments, which are based upon the exchange rate at the balance sheet date for assets and liabilities and the weighted average rate for the income statement, are recorded in the Accumulated Comprehensive Income (Loss) section of Stockholders’ Equity. Therefore, changes in the Canadian dollar, the Chilean peso or the Brazilian real relative to the U.S. dollar may have a material adverse effect on our financial condition and results of operations.

Our ability to service our indebtedness, to refinance our indebtedness or to fund our other liquidity needs is subject to various risks. Our ability to make scheduled payments on and to refinance our indebtedness depends on and is subject to our financial and operating performance, which in turn is affected by general and regional economic, financial, competitive, business and other factors, including the availability of financing in the banking and capital markets as well as the other risks described herein. In particular, demand for our products correlates to a significant degree to the level of residential construction activity in North America, which historically has been characterized by significant cyclicality. Over the last several years, housing starts remained below “normal” levels. There can be no assurance as to when, or if the housing market, will rebound to “normal levels”. Accordingly, we cannot assure you that our business will generate sufficient cash flows from operations or that future borrowings will be available to us in an amount sufficient to enable us to service our debt, to refinance our debt or to fund our other liquidity needs. If we are unable to service our debt obligations or to fund our other liquidity needs, we could be forced to curtail our operations, reorganize our capital structure or liquidate some or all of our assets in a manner that could cause the holders of our securities to experience a partial or total loss of their investment in us.

We have not independently verified the results of third-party research or confirmed assumptions or judgments upon which it may be based, and the forecasted and other forward-looking information contained therein is subject to inherent uncertainties. We refer in this report and other documents that we file with the SEC to historical, forecasted and other forward-looking information published by sources such as RISI (Resource Information Systems, Inc.), FEA (Forest Economic Advisors, LLC), Random Lengths and the U.S. Census Bureau that we believe to be reliable. However, we have not independently verified this information and, with respect to the forecasted and forward-looking information, have not independently confirmed the assumptions and judgments upon which it is based. Forecasted and other forward looking information is necessarily based on assumptions regarding future occurrences, events, conditions and circumstances and subjective judgments relating to various matters, and is

10

subject to inherent uncertainties. Actual results may differ materially from the results expressed or implied by, or based upon, such forecasted and forward-looking information.

    Initiatives to Upgrade Our Information Technology Infrastructure Involve Many Risks. We regularly implement business process improvement initiatives to optimize our performance. Our current initiatives include plans to further standardize the business processes and technology that support our strategies through implementation of an new software solution over the next few years. We may experience difficulties as we transition to these new or upgraded systems and processes, including loss of data and decreases in productivity as our personnel become familiar with new systems. In addition, transitioning to these new or upgraded systems requires significant capital investments and personnel resources. Difficulties in implementing new or upgraded information systems or significant system failures could disrupt our operations and have a material adverse effect on our business, financial condition, results of operations or cash flows. In addition, we will experience significant changes in our internal controls over financial reporting as our implementation progresses. If we are unable to manage these changes successfully, our ability to timely and accurately process transactions and report our results of operations could be adversely affected.

Our proposed acquisition of Ainsworth may intensify our exposure to existing risks and expose us to new risks. Ainsworth (Ainsworth Lumber Co. Ltd.) is exposed to substantially all of the risks to which we are currently exposed, as well as additional risks that arise from its specific circumstances. As a result, the completion of our proposed acquisition of Ainsworth will both intensify our exposure to existing risks (including those associated with our high degree of product concentration in OSB, demands on our senior management team and other key employees, capital needs and fluctuations in the exchange rate between the Canadian dollar and the U.S. dollar) and expose us to new risks. In addition, because the purchase price that we are obligated to pay Ainsworth shareholders consists substantially of a fixed amount of cash denominated in Canadian dollars and a fixed number of shares of LP common stock, we are exposed to risks associated with a potential decline in Ainsworth’s enterprise value as well as a potential strengthening of the Canadian dollar, and will pay greater value to the extent of any appreciation in the value of shares of LP common stock prior to the completion of the acquisition. The completion of the acquisition of Ainsworth is subject to specified conditions, including the receipt of certain regulatory approvals. The relevant governmental authorities may impose conditions on those approvals that could adversely affect the business, financial condition and results of operations of the combined enterprise. In addition, there can be no assurance that the combined enterprise will not experience a reduction in its allocated cutting rights under governmental tenures. The uncertainties regarding whether, when and the terms upon which the conditions to the acquisition will be satisfied may cause Ainsworth’s customers, suppliers and other business partners to delay, defer or otherwise alter decisions and approaches regarding Ainsworth and, together with uncertainties regarding post-acquisition staffing requirements and roles, may adversely affect Ainsworth’s ability to attract or retain key management personnel. In addition, the completion of the acquisition will involve the integration of companies that previously operated independently and will present a number of challenges (including the integration of operations, systems and

personnel) and risks (including possible unanticipated costs and liabilities, diversion of management’s attention and loss of key employees). Difficulties encountered in the transition and integration processes could have an adverse effect on the business, financial condition and results of operations of the combined enterprise and on the benefits sought to be realized from the acquisition.

The acreage noted above is the gross amount of the licenses and is not reflective of the amount of timber acreage that we currently manage. We also obtain wood from private parties in certain cases where the provincial governments require us to obtain logs from private parties prior to harvesting from the licenses to meet our raw materials needs.

ITEM 3.Legal Proceedings

Certain environmental matters and legal proceedings are discussed below.

ENVIRONMENTAL MATTERS

We are involved in a number of environmental proceedings and activities, and may be wholly or partially responsible for known or unknown contamination existing at a number of other sites at which we have conducted operations or disposed of wastes. Based on the information currently available, management believes that any fines, penalties or other costs or losses resulting from these matters will not have a material adverse effect on our financial position, results of operations, cash flows or liquidity.

ARS LITIGATION

On July 31, 2009, LP filed suit in the United States District Court for the Northern District of California captioned, Louisiana Pacific Corporation v. Money Market 1 Institutional Investment Dealer; Merrill Lynch & Co.,

Inc.; Merrill Lynch, Pierce, Fenner & Smith Incorporated; and Deutsche Bank Securities Inc. (Civil Action No.09cv3529). Merrill Lynch caused this case to be transferred to the United States District Court for the Southern District of New York (Civil Action No. 09 MD 2030) where Merrill Lynch had multiple similar cases pending as a result of a Multi-District Litigation Panel ruling. This matter arose out of LP's acquisition of certain ARS structured and underwritten by Merrill Lynch and Deutsche Bank with an approximate par value of $145.9 million. In the lawsuit, LP alleges that the defendants made misrepresentations and omissions of material facts in connection with the issuance of and the auctions for the ARS which constitute a violation of both state and federal securities laws, as well as common law fraud. LP seeks recovery of compensatory damages, rescission of the purchase of the securities at par value, consequential damages, punitive damages, attorneys' fees and any other damages the court deems appropriate under the circumstances.

On February 15, 2012, the Court granted Merrill Lynch's motion to dismiss the case against Merrill Lynch. LP is currently appealing this decision. Cases against MM1 remain pending in the Northern District of California and the Southern District of New York. LP is seeking default judgement against MM1 in both cases.

On November 30, 2012, we entered into a settlement agreement and mutual release with Deutsche Bank Securities Inc, (DBSI) relating to the case against DBSI. Pursuant to the agreement, DBSI, without admitting any liability or wrong-doing, paid to us the sum of $20 million, we dismissed the legal proceedings against DBSI with prejudice, and we and DBSI released the other from all claims and liabilities arising out of the sale and purchase of the auction rate securities and the related legal proceedings.

HARDBOARD TRIM LITIGATION

We were named in four putative class action lawsuits filed against us in United States District Courts during the first quarter of 2012 related to non-treated hardboard trim product formerly manufactured at our Roaring River, North Carolina hardboard plant: Brown v. Louisiana-Pacific Corporation., Case No. 4:12-CV-00102-RP-TJS (S.D. Iowa) (filed March 8, 2012, as a state-wide putative class); Holbrook v. Louisiana-Pacific Corporation, et al., Case No. 3:12-CV-00484-JGC (N.D. Ohio) (filed February 28, 2012, as a state-wide putative class); Bristol Village Inc. v. Louisiana-Pacific Corporation, et al., Case No. 1:12-CV-00263 (W.D.N.Y.) (filed March 30, 2012, as a state-wide putative class or, alternatively, as a nation-wide putative class) and Prevett v. Louisiana-Pacific, Case No. 6:12-CV-348-ORL-18-KRS (M.D. Fla) (filed March 5, 2012, as a state-wide putative class). A fifth lawsuit, Eugene Lipov v. Louisiana-Pacific, Case 1:12-CV-00439- JTN (W.D. Mich) (filed May 3, 2012) was filed as a statewide putative class action in the second quarter of 2012. These lawsuits follow two state-wide putative class action lawsuits previously filed against LP in United States District Courts:; Hart, et al. v. Louisiana-Pacific Corp., Case No. 2:08-CV-00047 (E.D.N.C.). and Ellis, et al. v. Louisiana-Pacific Corp., Case No. 3:11-CV-191 (W.D.N.C.) The Hart case was certified by the District Court as a class action on July 15, 2011.

15

Plaintiffs moved to combine pretrial matters through a Multidistrict Litigation (MDL) motion, filed as In Re: Louisiana-Pacific Corporation Trimboard Siding Marketing, Sales Practice and Products Liability Litigation MDL No. 2366 (U.S. Judicial Panel on Multidistrict Litigation) seeking to transfer all cases to the Eastern District of North Carolina. Louisiana-Pacific objected to the MDL motion and on June 11, 2012, the MDL Panel denied plaintiffs Motion to Transfer.

Subsequently, the Holbrook case was dismissed by the District Court on August 29, 2012 and has been appealed by the plaintiffs to the United States Court of Appeals for the Sixth Circuit. The Court of Appeals upheld the dismissal on all counts except the express warranty. The Ellis case was dismissed in its entirity by the District Court, and affirmed by the United States Court of Appeals for the Fourth Circuit on November 2, 2012. The Prevett v. Louisiana Pacific lawsuit was voluntarily dismissed by the plaintiffs on May 31, 2012. This lawsuit was replaced by Riley v. Louisiana-Pacific, Case No. 6:12-CV-00837-18 (M.D. Fla) (filed June 4, 2012 as a state-wide putative class). The Riley matter was voluntarily dismiss by the plaintiffs on December 17, 2013. The Lipov case was voluntarily dismissed by the plaintiffs on November 27, 2013. On August 30, 2013, the District Court in the Hart case decertified the class and granted summary judgment on the claims brought by the individual plantiffs dismissing the entire case. The plaintiff’s have appealed the dismissal and decertification to the United States Court of Appeals for the Fourth Circuit. Hart was the only case out of the eight lawsuits filed that was at one time certified as a class action.

The plaintiffs in these lawsuits were seeking to certify classes consisting of all persons that own structures within the respective states in which the lawsuit were filed (or, in some cases, within the United States) on which the hardboard trim in question is installed. The plaintiffs seek unspecified damages and injunctive and other relief under various state law theories, including negligence, violations of consumer protection laws, and breaches of implied and express warranties, fraud, and unjust enrichment. While some individual owners of structures within the putative classes may have valid warranty claims, we believe that the claims asserted on a class basis are without merit and we intend to defend these matters vigorously. We have established warranty reserves for the hardboard trim in question pursuant to our normal business practices, and we do not believe that the resolution of these lawsuits will have a material effect on our financial condition, results of operations, cash flows or liquidity.

OTHER PROCEEDINGS

LP is party to other legal proceedings. Based on the information currently available, LP believes that the resolution of such proceedings will not have a material adverse effect on its financial position, results of operations, cash flows or liquidity.

CONTINGENCY RESERVES

We maintain reserves for the estimated cost of the legal and environmental matters referred to above. However, as with any estimate, there is uncertainty of predicting the outcomes of claims and litigation and environmental investigations and remediation efforts that could cause actual costs to vary materially from current estimates. Due to various uncertainties, we cannot predict to what degree actual payments will exceed the recorded liabilities related to these matters. However, it is possible that, in either the near term or the longer term, revised estimates or actual payments will significantly exceed the recorded liabilities.

For information regarding our financial statement reserves for the estimated costs of the environmental and legal matters referred to above, see Note 18 of the Notes to financial statements included in item 8 in this report.

ITEM 7.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW

General

Our products are used primarily in new home construction, repair and remodeling, and manufactured housing. We also market and sell our products in light industrial and commercial construction and we have a modest export business. Our manufacturing facilities are primarily located in the U.S. and Canada, but we also operate two facilities in Chile and one facility in Brazil.

To serve these markets, we operate in four segments: North America Oriented Strand Board (OSB); Siding; Engineered Wood Products (EWP); and South America. OSB is the most significant segment, accounting for 51% of continuing sales in 2013, 48% in 2012 and 41% in 2011.

OSB is sold as a commodity for which sales prices fluctuate daily based on market factors over which we have little or no control. We cannot predict whether the prices of our products will remain at current levels, increase or decrease in the future.

Planned Acquisition of Ainsworth Lumber Co. Ltd.

On September 4, 2013, LP entered into an Arrangement Agreement (the “Arrangement Agreement”) with Ainsworth Lumber Co. Ltd., a British Columbia corporation (“Ainsworth”), providing an arrangement under British Columbia law whereby a wholly owned subsidiary of the Company will acquire all of the outstanding shares of Ainsworth capital stock in exchange for 0.114 shares of LP common stock (“LP Shares”) and C$1.94 in cash per Ainsworth common share (“Ainsworth Shares”) on the terms and subject to the conditions set forth therein (the “Transaction”). Although the Arrangement Agreement provides for Ainsworth shareholders to elect among cash consideration, share consideration and mixed consideration, proration provisions will ensure that the aggregate amounts of cash and LP Shares issued in the Transaction are fixed at approximately C$467 million and 27.5 million LP Shares, respectively.

The requisite approvals of the Transaction by Ainsworth shareholders and the Supreme Court of British Columbia were obtained on October 29, 2013 and October 31, 2013, respectively. As of the date of this report, the consummation of the Transaction remains subject to other closing conditions, including the expiration or termination of the waiting period under the HSR Act and the receipt of other regulatory approvals and clearances, including under the Canadian Competition Act and the Investment Act of Canada. LP and Ainsworth have agreed to endeavor to cause all closing conditions (including the receipt of regulatory approvals) to be satisfied, which under certain circumstances could require the taking of actions that could adversely affect the value of the Transaction to us.

On February 12, 2014, LP and Ainsworth entered into timing agreements with each of the Canadian Competition Bureau (the "CCB") and the Antitrust Division of the U.S. Department of Justice (the "DOJ") pursuant to which LP and Ainsworth agreed, subject to certain conditions, that they will not consummate the Transaction before March 13, 2014 without the consent of the CCB and the DOJ. This action followed the receipt by each of LP and Ainsworth of (a) a "supplementary information request" for additional information and documents from the CCB and (b) a "second request" for additional information from the DOJ in connection with the Transaction.

In connection with the entry into the timing agreements, LP and Ainsworth also amended the Arrangement Agreement to extend the outside date for completion of the Transaction from March 4 to April 18, 2014. The Arrangement Agreement permits either party to extend the outside date if required to obtain certain regulatory approvals.

The Arrangement Agreement contains certain termination rights for each of LP and Ainsworth. Either party may terminate the Arrangement Agreement if: (i) the parties mutually agree; (ii) the Transaction has not been consummated by April 18, 2014 (subject to extension in certain circumstances); (iii) a governmental authority issues a law or order prohibiting the Transaction; (iv) the other party materially breaches its representations, warranties or

20

covenants such that the applicable closing condition would not to be satisfied; or (v) the other party has incurred a Material Adverse Effect (as defined in the Arrangement Agreement).

We expect to fund the purchase price payable in the Transaction and related fees and expenses through a combination of cash on hand at LP and Ainsworth and borrowings under our revolving credit facility.

On October 17, 2013, Ainsworth issued a press release announcing that it had received the requisite consents in connection with its consent solicitation (the "Consent Solicitation") from holders of Ainsworth's 7.5% Senior Secured Notes due 2017 (the "Notes") . The press release also announced that Ainsworth has entered into a supplemental indenture relating to the Notes, which modified certain definitions in the indenture relating to the Notes (the "Indenture") so that the consummation of the Transaction pursuant to the Arrangement Agreement, and the designation by LP of members of Ainsworth’s board of directors upon and after the consummation of the Transaction, will not constitute a “Change of Control” under the Indenture and Ainsworth will not be required to make a “Change of Control Offer” under the Indenture in connection with the Transaction. Subject to the satisfaction or waiver of the conditions set forth in the solicitation statement distributed by Ainsworth to holders of the Notes, LP will make the consent payments contemplated thereby as and when they become due. Promptly following the consummation of the Transaction, LP will unconditionally guarantee the prompt payment and performance of the obligations of Ainsworth under the Indenture and the Notes.

The Transaction is expected to have a material effect on LP’s consolidated financial position, results of operations and cash flows. For additional information, see the Ainsworth Lumber Co. Ltd. Notice of Special Meeting and Management Proxy Circular furnished as Exhibit 99.1 to LP's Current Report on Form 8-K dated September 30, 2013.

Factors Affecting Our Results

Revenues and Operating Costs.

We derive our revenues from sales of our products. The unit volumes of products sold and the prices at which sales are made determine the amount of our revenues. These volumes and prices are affected by the overall level of demand for, and supply of, products of the type we sell and comparable or substitute products, and by competitive conditions.

Our operating results reflect the relationship between the amount of our revenues and our costs of production and other operating costs and expenses. Our costs of production are affected by, among other factors, costs of raw materials (primarily wood fiber and various petroleum-based resins) and energy costs, which in turn are affected by the overall market supply of and demand for these manufacturing inputs.

Demand for Building Products

Demand for our products correlates to a significant degree to the level of residential construction activity in North America, which historically has been characterized by significant cyclicality. This activity can be further delineated into three areas: (1) new home construction; (2) repair and remodeling; and (3) manufactured housing.

New Home Construction. Demand for our products correlates to a significant degree to the level of new home construction activity in North America, which historically has been characterized by significant cyclicality. The U.S. Census Bureau reported that actual single and multi-family housing starts in 2013 were about 18% higher than 2012, which were about 29% higher than such housing starts in 2011. However when comparing 2013 housing starts to the average of the last ten years as reported by the U.S. Census Bureau, 2013 housing starts were about 20% lower than that average. We believe that the reduced level of building is due to the continued high levels of unemployment, delayed household formations due to the sluggish economy, foreclosure activity and a more restrictive mortgage market.

While near term residential construction is constrained in the U.S., positive long-term fundamentals exist. Increased immigration, the changing age distribution of the population, the high number of adults living with their parents and historically low interest rates are expected to lead to more household formations. The chart below, which

21

is based on data published by U.S. Census Bureau, provides a graphical summary of new housing starts for single and multi-family in the U.S. showing actual and rolling five and ten year averages for housing starts in thousands.

Repair and Remodeling. Demand for building materials to support home improvement projects is largely tied to the size and age of the existing housing stock in North America and consumer confidence. In this regard, the 1970s and 1980s had some of the highest levels of building activity. This puts these homes at an age of approximately 30-40 years, which has been shown to be consistent with the highest per home expenditure rate on repair and remodeling. With the rise in the number and scale of home improvement stores in North America, individuals now have ready and convenient access to obtain the building materials needed for repair and remodeling, as well as increased access to installation services.

Manufactured Housing. Over the last several years, manufactured housing has suffered. There are several factors that have led to the decline in the number of manufactured housing units produced, including a lack of available financing, increased ability of potential customers to purchase site-built starter homes and financial difficulties at some of the larger manufactured housing producers.

Supply of Building Products

OSB is a commodity product, and it is, along with all of our products, subject to competition from manufacturers worldwide. Product supply is influenced primarily by fluctuations in available manufacturing capacity and imports. According to FEA (Forest Economic Advisors, LLC), total North American OSB annual production capacity is projected to increase by approximately 2.6 billion square feet in the period from 2014 to 2018 while plywood production capacity is projected to increase by 0.2 billion square feet for the same period. According to FEA, OSB accounted for approximately 65% of North American structural panel production capacity in 2013, with plywood accounting for the remainder. Going forward, it is expected that OSB will continue to capture market share from plywood. FEA forecasts, as of December 2013, that OSB will comprise approximately 67% of the

22

structural panel market by 2018. The chart below, which is based on data and forecasts published by FEA, depicts past and forecasted North America structural wood production capacities in billions of square feet.

Putting Demand and Supply Together

As noted above, demand for building products is influenced by the general economy, demographics and need for housing. In the case of OSB, generally, lower demand coupled with higher production capacity will result in lower pricing. The chart below, as calculated by FEA (as of December 2013), shows the demand capacity ratio (demand divided by supply) for OSB in 2010 through 2013 as well as FEA’s forecast through 2018 based upon estimated future demand and supply.

23

Product Pricing.

Historical prices for our products have been volatile, and we, like other participants in the building products industry, have limited influence over the timing and extent of price changes for our products. The estimated average North Central wholesale price for OSB (per thousand square feet 7/16” basis) from 2007 through 2013, as published by Random Lengths, an industry publication, is presented below. FEA’s forecast (as of December 2013) for average North Central wholesale pricing for OSB (per thousand square feet 7/16” basis) through 2018 is also shown.

Implementation of System Upgrade

During 2012, we conducted a thorough review of our business to assess our current information systems. After extensive study and analysis, we determined that a system upgrade was required. We do anticipate that this initial system upgrade will provide us benefits in terms of reporting and data analysis in addition to upgrading our aging systems. We anticipate the cost of implementation, both capital and expense, to be approximately $30 million which will consist primarily of software and hardware costs, system integration costs, labor costs, and data migration. We anticipate completing the first stage of the systems upgrade in early 2014 and will then embark on further enhancements.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ESTIMATES

A discussion of our significant accounting policies and significant accounting estimates and judgments is presented in Note 1 of the Notes to the financial statements in item 8 of this report. Throughout the preparation of the financial statements, we employ significant judgments in the application of accounting principles and methods. These judgments are primarily related to the assumptions used to arrive at various estimates. For 2013, these significant accounting estimates and judgments include:

Legal Contingencies. Our estimates of loss contingencies for legal proceedings are based on various judgments and assumptions regarding the potential resolution or disposition of the underlying claims and associated costs. In making judgments and assumptions regarding legal contingencies for ongoing class action settlements, we consider, among other things, discernible trends in the rate of claims asserted and related damage estimates and information obtained through consultation with statisticians and economists, including statistical analysis of potential outcomes based on experience to date and the experience of third parties who have been subject to product-related claims judged to be comparable. Due to the numerous variables associated with these judgments and assumptions, both the precision and reliability of the resulting estimates of the related loss contingencies are subject to substantial uncertainties. We regularly monitor our estimated exposure to these contingencies and, as additional information becomes known, may change our estimates significantly.

Environmental Contingencies. Our estimates of loss contingencies for environmental matters are based on various judgments and assumptions. These estimates typically reflect judgments and assumptions relating to the probable nature, magnitude and timing of required investigation, remediation and/or monitoring activities and the probable cost of these activities, and in some cases reflect judgments and assumptions relating to the obligation or willingness and ability of third parties to bear a proportionate or allocated share of the cost of these activities, including third parties who purchased assets from us subject to environmental liabilities. We consider the ability of third parties to pay their apportioned cost when developing our estimates. In making these judgments and assumptions related to the development of our loss contingencies, we consider, among other things, the activity to date at particular sites, information obtained through consultation with applicable regulatory authorities and third-party consultants and contractors and our historical experience at other sites that are judged to be comparable. Due to the numerous variables associated with these judgments and assumptions, and the effects of changes in governmental regulation and environmental technologies, both the precision and reliability of the resulting estimates of the related contingencies are subject to substantial uncertainties. We regularly monitor our estimated exposure to environmental loss contingencies and, as additional information becomes known, may change our estimates significantly. At December 31, 2013, we excluded from our estimates approximately $2.1 million of potential environmental liabilities that we estimate will be allocated to third parties pursuant to existing and anticipated future cost sharing arrangements.

Impairment of Long-Lived Assets. We review the long-lived assets held and used by us (primarily property, plant and equipment and timber and timberlands) for impairment when events or changes in circumstances indicate that the carrying amount of assets may not be recoverable. We consider the necessity of undertaking such a review at least quarterly, and also when certain events or changes in circumstances occur. Events and changes in circumstances that may necessitate such a review include, but are not limited to: a significant decrease in the market price of a long-lived asset or group of long-lived assets; a significant adverse change in the extent or manner in which a long-lived asset or group of long-lived assets is being used or in its physical condition; a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset or group of long-lived assets, including an adverse action or assessment by a regulator; an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset or group of long-lived assets; current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or group of long-lived assets; and current expectation that, more likely than not, a long-lived asset or group of long-lived assets will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. Identifying these events and changes in circumstances, and assessing their impact on the appropriate valuation of the affected assets under accounting principles generally accepted in the U.S., requires us to make judgments, assumptions and estimates.

25

In general, for assets held and used in our operations, impairments are recognized when the carrying amount of the long-lived asset or groups of long-lived assets is not recoverable and exceeds the fair value of the asset or group of assets. The carrying amount of a long-lived asset or groups of long-lived assets is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the assets or group of assets. The key assumptions in estimating these cash flows relate to future production volumes, pricing of commodity or specialty products and future estimates of expenses to be incurred as reflected in our long-range internal planning models. Our assumptions regarding pricing are based upon the average pricing over the commodity cycle (generally five years) due to the inherent volatility of commodity product pricing, and reflect our assessment of information gathered from industry research firms, research reports published by investment analysts and other published forecasts. Our assumptions regarding expenses reflect our expectation that we will continue to reduce production costs to offset inflationary impacts.

When impairment is indicated for assets held and used in our operations, the book values of the affected assets are written down to their estimated fair value, which is generally based upon discounted future cash flows associated with the affected assets. When impairment is indicated for assets to be disposed of, the book values of the affected assets are written down to their estimated fair value, less estimated selling costs. Consequently, a determination to dispose of particular assets can require us to estimate the net sales proceeds expected to be realized upon such disposition, which may be less than the estimated undiscounted future net cash flows associated with such assets prior to such determination, and thus require an impairment charge. In situations where we have experience in selling assets of a similar nature, we may estimate net sales proceeds on the basis of that experience. In other situations, we hire independent appraisers to estimate net sales proceeds.

Due to the numerous variables associated with our judgments and assumptions relating to the valuation of assets in these circumstances, and the effects of changes in circumstances affecting these valuations, both the precision and reliability of the resulting estimates of the related impairment charges are subject to substantial uncertainties and, as additional information becomes known, we may change our estimates significantly.

Income Taxes. The determination of the provision for income taxes, and the resulting current and deferred tax assets and liabilities, involves significant management judgment, and is based upon information and estimates available to management at the time of such determination. The final income tax liability to any taxing jurisdiction with respect to any calendar year will ultimately be determined long after our financial statements have been published for that year. We maintain reserves for known estimated tax exposures in federal, state and international jurisdictions; however, actual results may differ materially from our estimates.

Judgment is also applied in determining whether deferred tax assets will be realized in full or in part. When we consider it to be more likely than not that all or some portion of a deferred tax asset will not be realized, a valuation allowance is established for the amount of the deferred tax asset that is estimated not to be realizable. As of December 31, 2013, we had established valuation allowances against certain deferred tax assets, primarily related to state and foreign carryovers of net operating losses, credits and capital losses. We have not established valuation allowances against other deferred tax assets based upon positive evidence such as recent earnings history, generally improving economic conditions and deferred tax liabilities which we anticipate to reverse within the carry forward period. Accordingly, changes in facts or circumstances affecting the likelihood of realizing a deferred tax asset could result in the need to record additional valuation allowances.

Pension Plans. Most of our U.S. employees and many of our Canadian employees participate in defined benefit pension plans sponsored by LP. We account for the consequences of our sponsorship of these plans in accordance with accounting principles generally accepted in the U.S., which require us to make actuarial assumptions that are used to calculate the related assets, liabilities and expenses recorded in our financial statements. While we believe we have a reasonable basis for these assumptions, which include assumptions regarding long-term rates of return on plan assets, life expectancies, rates of increase in salary levels, rates at which future values should be discounted to determine present values and other matters, the amounts of our pension related assets, liabilities and expenses recorded in our financial statements would differ if we used other assumptions. See further discussion related to pension plans below under the heading “Defined Benefit Pension Plans” and in Note 13 of the Notes to the consolidated financial statements included in item 8 of this report.

26

Workers’ Compensation. We are self insured for most of our U.S. employees’ workers compensation claims. We account for these plans in accordance with accounting principles generally accepted in the U.S., which require us to make actuarial assumptions that are used to calculate the related assets, liabilities and expenses recorded in our financial statements. While we believe we have a reasonable basis for these assumptions, which include assumptions regarding rates at which future values should be discounted to determine present values, expected future health care costs and other matters, the amounts of our liabilities and related expenses recorded in our financial statements would differ if we used other assumptions.

Warranty Obligations. Customers are provided with a limited warranty against certain defects associated with our products for periods of up to fifty years. We estimate the costs to be incurred under these warranties and record a liability in the amount of such costs at the time product revenue is recognized. Factors that affect our warranty liability include the historical and anticipated rates of warranty claims and the cost of resolving such. We periodically assess the adequacy of our recorded warranty liability for each product and adjust the amounts as necessary. While we believe we have a reasonable basis for these assumptions, actual warranty costs in the future could differ from our estimates.

NON-GAAP FINANCIAL MEASURES

In evaluating our business, we utilize several non-GAAP financial measures. A non-GAAP financial measure is generally defined by the SEC as one that purports to measure historical or future financial performance, financial position or cash flows, but excludes or includes amounts that would not be so excluded or included under applicable GAAP guidance. In this report on Form 10-K, we disclose earnings (loss) from continuing operations before interest expense, taxes, depreciation and amortization (“EBITDA from continuing operations”) which is a non-GAAP financial measure. Additionally, we disclose Adjusted EBITDA from continuing operations which further adjusts EBITDA from continuing operations to exclude stock based compensation expense, (gain) loss on acquisitions, (gain) loss on sales or impairment of joint ventures interest and long lived assets, other operating charges and credits, (gain) loss on early debt extinguishment, acquisition expenses, (gain) loss on litigation settlements, other than temporary asset impairments, investment income and depreciation included in equity in (income) loss of unconsolidated affiliates. Neither EBITDA from continuing operations nor Adjusted EBITDA from continuing operations is a substitute for the GAAP measure of net income or operating cash flows or for any other GAAP measures of operating performance or liquidity.

We have included EBITDA from continuing operations and Adjusted EBITDA from continuing operations in this report on Form 10-K because we use them as important supplemental measures of our performance and believe that they are frequently used by securities analysts, investors and other interested persons in the evaluation of companies in our industry, some of which present EBITDA when reporting their results. We use EBITDA from continuing operations and Adjusted EBITDA from continuing operations to evaluate our performance as compared to other companies in our industry that have different financing and capital structures and/or tax rates. It should be noted that companies calculate EBITDA and Adjusted EBITDA differently and, therefore, our EBITDA and Adjusted EBITDA measures may not be comparable to EBITDA and Adjusted EBITDA reported by other companies. Our EBITDA and Adjusted EBITDA measures have material limitations as performance measures because they exclude interest expense, income tax (benefit) expense and depreciation and amortization which are necessary to operate our business or which we otherwise incur or experience in connection with the operation of our business.

RESULTS OF OPERATIONS

We reported net income of $177.1 million ($1.23 per diluted share) in 2013, which was comprised of income from continuing operations of $177.4 million ($1.23 per diluted share) and a loss from discontinued operations of $0.3 million ($0.00 per diluted share). This compares to net income of $28.8 million ($0.20 per diluted share) in 2012, which was comprised of income from continuing operations of $29.5 million ($0.20 per diluted share) and a loss from discontinued operations of $0.7 million ($0.00 per diluted share). We reported a net loss attributable to LP of $181.3 million ($1.36 per diluted share) in 2011, which was comprised of loss from continuing operations attributed to LP of $175.7 million ($1.32 per diluted share) and a loss from discontinued operations of $5.6 million ($0.04 per diluted share).

Net sales in 2013 were $2.1 billion, an increase of 23% from 2012 net sales of $1.7 billion. Net sales in 2012 as compared to 2011 were higher by 27%. Sales in 2013 were positively impacted by increases in OSB selling prices relative to 2012 and 2011.

Our results of operations for each of our segments are discussed below, as are results of operations for the “other” category which comprises other products that are not individually significant. See Note 26 of the Notes to the consolidated financial statements included in item 8 of this report for further information regarding our segments.

OSB

Our OSB segment manufactures and distributes OSB structural panel products in North America and certain export markets. OSB is an innovative, affordable and environmentally smart product made from wood strands arranged in layers and bonded with resin. We believe we are the largest and one of the most efficient producers of OSB in North and South America.

According to FEA, it is estimated for 2013 that OSB accounted for approximately 61% of the structural panel consumption in North America with plywood accounting for the remainder. We estimate that the overall North American structural panel market (based upon 2013 housing starts) was 28.3 billion square feet with the OSB market comprising an estimated 17.3 billion square feet of this market. Based upon our production in 2013 of 4.1 billion square feet, we estimate that we account for 24% of the North American OSB market and 14% of the overall North American structural panel market.

To enhance our industry leading position in the OSB business, we plan to: (1) leverage our expertise in OSB to capitalize on new opportunities for revenue growth through new product lines; (2) improve net realizations relative to weighted-average OSB regional pricing; (3) reduce costs and improve throughput and recovery by continuing to focus on efficiency, raw materials cost reductions and logistics; and (4) manage our capacity to meet our customers' expected needs for OSB demand.

OSB is manufactured through the use of wood strands arranged in layers and bonded with resins and wax. Significant cost inputs to produce OSB and approximate breakdown percentages for the year ended December 31, 2013 include wood (33%), resin and wax (24%), labor and burden (15%), utilities (6%) and manufacturing and other (22%).

The increase in selling prices favorably impacted operating results and Adjusted EBITDA from continuing operations by approximately $170 million for 2013 as compared to 2012. Sales volumes increased due to the improved housing market as well as continued movement into industrial applications and increased exports. As of December 31, 2013, one of our OSB mills was indefinitely curtailed. Two mills were restarted during 2013.

2012 compared to 2011

OSB prices increased compared to 2011. The increase in OSB prices was likely due to strengthening of the relationship between regional supply and demand based upon currently operating facilities across the industry. The increase in selling price favorably impacted operating results and Adjusted EBITDA from continuing operations by approximately $201 million for 2012 as compared to 2011. Sales volumes increased due to the improved housing market as well as continued movement into industrial applications and increased exports. As of December 31, 2012, three of our OSB mills were indefinitely curtailed.

Siding

Our siding segment produces and markets wood-based siding and related accessories and commodity OSB products. We believe that we are a leading wood composite exterior siding producer in North America. We manufacture exterior siding and other cladding products for the residential and commercial building markets, retain and non-residential structures. Additionally, we are seeking to optimize our current capacity by extending the hardboard lifecycle through innovative new products and features.

Our strategy is to drive product innovation by utilizing our technological expertise in wood and wood composites to better address the needs of our customers. We intend to increase our product offerings and production capacity of higher margin, value-added products through the addition of lower cost plants or the conversion of OSB plants from commodity structural panel production to OSB-based exterior siding products.

2013 compared to 2012

Siding sales volumes increased in our SmartSide^® siding line due to continued penetration in several key focus markets including retail, repair and remodel markets, sheds and increased housing demand. Sales prices in our SmartSide siding product as compared to the prior year increased due primarily to changes in product mix as well as price increases implemented to offset increases in raw material costs.

Sales volumes declined slightly in our Canexel siding lines due to lower demand in Canada and international sales, primarily Europe. Sales prices were down slightly between years due to the impact of the fluctuations in the Canadian dollar related to the U.S dollar. Sales prices in the Canadian dollar increased by 3% between years.

Sales prices increased for our commodity OSB products as described in the discussion of our OSB segment above. The increase in selling price favorably impacted operating results and Adjusted EBITDA from continuing operations by approximately $8 million for 2013 as compared to 2012.

Overall, the increases in operating results for our siding segment for 2013 as compared to 2012 were due to increased OSB pricing and higher sales volumes in our SmartSide^® siding line.

2012 compared to 2011

Siding sales volumes increased in our SmartSide^® siding line due to continued penetration in several key focus markets, including retail, repair and remodel markets and sheds. Sales prices in our SmartSide^® siding product as compared to the prior year increased due primarily to changes in product mix as well as a price increase implemented at the beginning of the second quarter of 2012. The price increase was implemented to offset increases in raw material costs.

Sales volumes declined slightly in our CanExel siding lines due to our distributors balancing supply and demand and lower shipments to Europe. Sales prices were flat between years.

Sales prices increased for our commodity OSB products as described in the discussion of our OSB segment above. The increase in selling price favorably impacted operating results and Adjusted EBITDA from continuing operations by approximately $11 million for 2012 as compared to 2011.

33

Overall, the increases in operating results for our siding segment for 2012 as compared to 2011 was primarily due to increased OSB pricing and higher sales volumes in our SmartSide^® siding line.

I-joist	10	%	17	%	1	%	11	%

2013 compared to 2012

Sales volumes increased in LVL/LSL and I-joist due to increased demand in the U.S. housing market with offsetting reductions in exports. Net average selling prices increased due to price increases implemented to offset higher raw material costs.

The results of operations were lower for 2013 as compared to 2012 due to increases in raw material costs, primarily OSB and lumber, which were partially offset by increases in sales prices.

34

2012 compared to 2011

Sales volumes increased in LVL/LSL and I-joist due to increased demand in the U.S. housing market with offsetting reductions in exports. Net average selling prices remained relatively flat in both product lines.

Improvements in our results of operations for 2012 as compared to the prior year are primarily related to reduced depreciation at our LSL facility due to an impairment recorded in the third quarter of 2011.

2013 compared to 2012

In our Chilean operations, sales volumes decreased due to increased imports from North America. Sales volumes in Brazil decreased due to reduced production related to maintenance work completed on its press during the year.

Sales prices in Chile increased in 2013, compared to 2012 due to price increases implemented. Sales prices in Brazil increased slightly due to the impact of the fluctuations in the Brazilian real related to the U.S. dollar as a majority of these sales are in local markets. Local currency selling prices in Chile increased by 5% and local currency selling prices in Brazil increased by 12% in 2013 as compared to 2012.

2012 compared to 2011

In our Chilean operations, sales volumes increased due to continued penetration in local markets. Sales volumes in Brazil increased due to increased penetration in local markets as well as continued increases in exports to China. Changes in price are due to the impact of the fluctuations in the Chilean peso and Brazil real relative to the U.S. dollar as a majority of these sales are in local markets. In terms of changes in sales price based upon local

2012 compared to 2011

Overall, operating results associated with these activities were positively impacted by the performance of our U.S. Greenfiber joint venture.

GENERAL CORPORATE AND OTHER EXPENSE, NET

Net general corporate expense was $96.7 million in 2013 as compared to $78.7 million in 2012 and $66.4 million in 2011. General corporate and other expenses primarily consist of corporate overhead such as wages and benefits for corporate personnel, professional fees, insurance, travel costs, non-product specific marketing and other expenses. The increase in 2013 as compared to 2012 was due to costs associated with our system upgrade as well as increased costs associated with the proposed acquisition of Ainsworth Lumber Co. Ltd. The increase in 2012 as compared to 2011 was due to higher accruals under the management incentive program as well as increased legal costs. During 2011, we did not pay any management incentives.

EQUITY IN EARNINGS OF UNCONSOLIDATED AFFILIATES

We have participated in several joint venture arrangements. These include: (1) a joint venture with Casella Waste Management Systems, Inc. to produce cellulose insulation; (2) a joint venture with Canfor Corporation to construct and operate an OSB mill in British Columbia; and (3) a joint venture with Resolute Forest Products to construct and operate two I-joist facilities in Quebec.

In 2000, we and Casella Waste Management Systems, Inc., each contributed most of the assets of our respective cellulose insulation operations to a joint venture, U.S. GreenFiber, LLC (GreenFiber). Pursuant to the joint venture agreement, each company owned 50% of GreenFiber. GreenFiber elected to be treated as a partnership for income tax purposes and therefore the entity is not taxed directly. The results of this operation are included within Other Products. In December of 2013, we sold our 50% interest in GreenFiber and recognized a gain of $1.2 million.

In 2003, we and Canfor Corporation, entered into a joint venture to construct and operate an 820 million square foot OSB facility in British Columbia, Canada. Pursuant to the joint venture agreement, each company owns 50% of the venture, with LP being responsible for all North American sales from this facility. The results of this operation is included in our OSB segment. In 2013, we acquired the remaining 50% interest owned by Canfor Corporation.

In 2002, we entered into a joint venture with Resolute Forest Products to construct and operate an I-joist facility in Eastern Canada. Pursuant to the joint venture agreement, each company owns 50% of the venture.

37

Subsequently, the joint venture constructed and commenced operating a second I-joist facility in Eastern Canada. The results of these operations are included in the EWP segment.

DISCONTINUED OPERATIONS

Included in discontinued operations for 2013, 2012 and 2011 are the carrying costs of mills that have been closed and divested and related warranty costs associated with such facilities. These operations include residual losses of mills divested in past years and associated warranty and other liabilities associated with these operations.

2013 compared to 2012

Included in discontinued operations for 2013 is a gain of $1.7 million on the sale of the moulding operations that was recognized in the third quarter of 2013 as well as a $2 million increase in our warranty reserves associated with discontinued products.

2012 compared to 2011

Included in the loss on discontinued operations for 2012 is an increase in our warranty reserves associated with discontinued products of $3.6 million as well as residual costs associated with mills that have been previously discontinued and sold.

INCOME TAXES

We recorded a tax provision in continuing operations of $41.1 million in 2013 and $7.0 million in 2012, and income tax benefit in continuing operations of $41.1 million in 2011. For 2013, the primary difference between the U.S. statutory rate of 35% and the effective rate on our continuing operations relates to state income taxes,  the effect of foreign tax rates and exchange rates and reductions in valuation allowances previously established on certain deferred tax assets for foreign and state net operating loss carryovers.

For 2012, the primary difference between the U.S. statutory rate of 35% and the effective rate on our continuing operations relates to state income taxes, the effect of foreign tax rates and adjustments to previously recorded deferred tax liabilities.

We paid $6.8 million of cash taxes and received $0.9 million in cash tax refunds in 2013 and expect to receive $2.3 million in related refunds from prior years in 2014.

DEFINED BENEFIT PENSION PLANS

We maintain several qualified and non-qualified defined benefit pension plans in the U.S. and Canada that cover a substantial portion of our employees. The measurement of liabilities related to these plans is based on management’s interpretation of the applicable plan provisions and assumptions related to future events, including expected return on plan assets and rate of compensation increases. The discount rate reflects the rate at which benefits could be effectively settled on the measurement date. The projected payment for each year is discounted using the rates specified by the yield curve. The sum of these discounted payments is the benefit obligation. The discount rate disclosed is the single rate applied to all projected payments that creates an equivalent obligation. Actual pension plan asset investment performance will either reduce or increase unamortized pension losses at the end of any fiscal year, which ultimately affects future pension costs. See Note 13 of the Notes to the consolidated financial statements included in item 8 of this report for further information on these plans.

38

The table below quantifies the approximate impact on our plans, as of December 31, 2013, of a one-half percentage point decrease in our assumptions for discount rate and expected return on assets, holding other assumptions constant:

Dollars in millions
Increase in annual costs for 2014:
Discount rate	$	0.7
Expected long-term rate of return	$	1.3
Increase in projected benefit obligation:
Discount rate	$	17.8

For our U.S. plans, we used a long term rate of return assumption of 7.25% for 2013 and 2012 to calculate the net periodic pension costs. For our Canadian plans, we used a long-term rate of return assumption of 3.75% to 4.5% to calculate 2013 and 2012 net periodic pension costs. For 2013, our net periodic pension cost was $7.2 million and we estimate for 2014, our net periodic pension cost will be $5.6 million. This estimate assumes that we will have no curtailment or settlement expenses in 2014. If a settlement or curtailment does occur in 2014, this estimate may change significantly. We estimate in 2014, we will contribute approximately $2.0 million to $5.0 million to our Canadian defined benefit pension plans.

LEGAL AND ENVIRONMENTAL MATTERS

For a discussion of legal and environmental matters involving us and the potential impact thereof on our financial position, results of operations and cash flows, see Item 3 in this report as well as Note 18 in the Notes to the consolidated financial statements included in item 8 of this report.

LIQUIDITY AND CAPITAL RESOURCES

Overview

Our principal sources of liquidity are existing cash and investment balances, cash generated by our operations and our ability to borrow under such credit facilities as we may have in effect from time to time. We may also from time to time issue and sell equity, debt or hybrid securities or engage in other capital market transactions.

Our principal uses of liquidity are paying the costs and expenses associated with our operations, servicing outstanding indebtedness and making capital expenditures. We may also from time to time prepay or repurchase outstanding indebtedness, acquire assets or businesses that are complementary to our operations. Any such repurchases may be commenced, suspended, discontinued or resumed, and the method or methods of effecting any such repurchases may be changed, at any time or from time to time without prior notice.

Operating Activities

During 2013, we generated $242.5 million of cash from operations as compared to generating $111.8 million of cash from operations in 2012. This change reflects improved results of operations for 2013. As of December 31, 2013, our trade receivables decreased $6.8 million from December 31, 2102 and the balance was 99% current. Our trade accounts payable increased by $12.0 million from the prior year primarily due to the increases in inventory and our salary and wages payable increasing by $10.4 million due to timing of payroll disbursements. During 2013, we made $0.5 million in contingency payments and $12.5 million in warranty payments.

During 2012, we generated $111.8 million of cash from operations as compared to using $40.2 million of cash for operations in 2011. This change reflects improved results of operations for 2012. During 2012, we received tax refunds of $0.3 million (net of payments). As of December 31, 2012, our trade receivables increased about $15 million during 2012 and the balance was 99% current, which is comparable to prior years with no substantial changes in terms of sales. Our trade accounts payable increased by $12.5 million from the prior year primarily due to increases in inventory and our salary and wages payable increasing by $11.0 million due to expected management

39

incentive payouts as well as timing on payroll. During 2012, we made $1.4 million in contingency payments and $11.6 million in warranty payments.

During 2011, we used $40.2 million of cash in operations as compared to generating $47.8 million in 2010. This change was related to increased operating losses, higher inventories and lower tax refunds. During 2011, we received tax refunds of $25.0 million (net of payments). Trade receivables were relatively flat between 2011 and 2010. As of December 31, 2011, our trade receivables balance was 99% current, which is comparable to prior years with no substantial changes in terms of sales. Non-trade receivables decreased by $1.6 million due to lower interest receivables resulting from principal payments received during 2011. Our trade accounts payable increased by $4.8 million from the prior year primarily due to the increases in inventory and our salary and wages payable declining by $7.4 million due to reduction in expected management incentive payouts. During 2011, we made $2.3 million in contingency payments and $12.9 million in warranty payments.

Investing Activities

During 2013, we used $17.4 million in cash from investing activities. Capital expenditures for 2013 were $75.6 million, primarily related to growth and maintenance capital, initial costs associated with our software upgrade and minor capital related to our announced expansion in South America. We received distributions from our joint ventures of $13.9 million, $16.7 million from the sale of assets and $0.7 million in cash no longer required to collaterize certain long-term obligations, $91.4 million of payments on notes receivable from asset sales and $2.9 million from the sale of our U.S. GreenFiber joint venture. We also used $67.4 million in the acquisition of our Peace Valley joint venture. Additionally, included in accounts payable is $6.4 million related to capital expenditures that had not yet been paid as of December 31, 2013.

During 2012, we generated $21.5 million in cash from investing activities. Capital expenditures for 2012 were $31.2 million, primarily related to maintenance capital, initial costs associated with our software upgrade and minor capital related to our announced expansion in South America. We received distributions from our joint ventures of $12.7 million, $9.2 million from the sale of assets and $0.8 million in cash no longer required to collaterize certain long-term obligations. We also received $20.0 million from the settlement of litigation related to ARS and $10.0 million of payments on notes receivable from asset sales. Additionally, included in accounts payable is $4.1 million related to capital expenditures that had not yet been paid as of December 31, 2012.

During 2011, we generated $7.7 million in cash from investing activities. Capital expenditures for 2011 were $21.4 million, primarily related to maintenance capital. Additionally, we funded our joint ventures $9.6 million. We received $19.1 million on the sale of investments with maturities in excess of 90 days, $1.3 million on the sale of assets and $18.3 million in cash no longer required to collaterize certain long-term obligations. Additionally, included in accounts payable is $0.8 million related to capital expenditures that had not yet been paid as of December 31, 2011.

Capital expenditures in 2014 are expected to be approximately $100 million related to projects for productivity improvements and maintenance projects.

Financing Activities

In 2013, net cash used in financing activities was $126.4 million. During 2013, we used $113.2 million to repay outstanding debt, $12.1 million for taxes related to net share settlement of equity awards and $1.2 million for debt issuance fees. We received $0.1 million from the sale of common stock under equity plans.

In 2012, net cash provided from financing activities was $92.1 million. During 2013, we issued $350.0 million of 7.5% Senior Notes due 2020, and used approximately $248.6 million of the proceeds of this issuance to fully retire our Senior Secured Notes due in 2017 and pay related transaction costs and expenses. We also received $1.3 million from the sale of common stock under equity plans.

In 2011, net cash used in financing activities was $15.7 million. During 2011, we redeemed the 25% non-controlling interest in our Brazilian OSB operation for $24.0 million. In connection with this redemption, we borrowed $10.0 million under a Brazilian export financing facility established to facilitate the redemption. As part of our ongoing cost reduction activities, we renegotiated our Chilean loan which required us to pay a financing fee of

40

$1.0 million and allowed us to release our restricted cash associated with letters of credit supporting Chilean borrowings and lower the interest rate on this loan. We also paid $0.5 million of financing fees in connection with amendments to our asset-based revolving credit facility.

CREDIT AGREEMENTS

In December 2013, we entered into a credit agreement with various lenders and American AgCredit, PCA, as administrative agent and CoBank, ACB, as letter of credit issuer. The credit agreement provides for a $200 million revolving credit facility, with a $60 million sublimit for letters of credit. The credit facility terminates and all loans made under the credit agreement become due in December 2018. As of December 31, 2013, no revolving borrowings had been made under the credit facility.

Certain of our existing and future wholly owned domestic subsidiaries guaranty our obligations under the credit facility. Subject to certain limited exceptions, obligations under the credit facility are secured by a lien on substantially all of our personal property and the personal property of the our subsidiaries that are guarantors under the credit facility.

The credit agreement contains customary covenants applicable to us and certain of our subsidiaries, including restrictions on, among other things, our ability to: incur debt; incur liens; declare or make distributions to our stockholders; make loans and investments; repay debt; enter into mergers, acquisitions and other business combinations; form or acquire subsidiaries; amend or modify our governing documents; enter into hedging arrangements; engage in other businesses other than our business as currently conducted; and enter into transactions with affiliates. The credit agreement also contains financial covenants that require us and our consolidated subsidiaries to have, as of the end of each quarter, (i) a capitalization ratio (i.e., funded debt to total capitalization) of no more than 40% and (ii) unrestricted cash and cash equivalents of at least (a) $350,000,000 until closing of our acquisition of Ainsworth Lumber Co. Ltd. and (b) $250,000,000 thereafter, in each case calculated in the manner specified in the credit agreement. As of December 31, 2013, we were in compliance with all financial covenants under the credit agreement. The credit agreement contains customary events of default, the occurrence of which could result in the acceleration of our obligation to repay the indebtedness outstanding thereunder.

Obligations under the indenture governing our Senior Notes due 2020 are unsecured and not presently guaranteed by any of our subsidiaries. The indenture contains customary covenants applicable to us and our subsidiaries, other than certain unrestricted subsidiaries, including restrictions on actions and activities that are restricted under the credit facility. The indenture also contains customary events of default, the occurrence of which could result in acceleration of our obligations to repay the indebtedness outstanding thereunder.

LP Chile is a party to a term loan agreement with Banco de Credito e Inversiones for UF 943,543.7391 (equivalent to $39 million at the time of inception). The loan agreement has a term of 10 years with semi-annual principal payments beginning in June of 2012. The loan bears interest at UF plus 3.9% per annum, and is secured by a first priority security interest in substantially all of the real property owned by LP Chile. The loan contains various restrictive covenants and requires the maintenance by LP Chile of a debt to equity ratio of less than or equal to 1. If LP Chile is late in making payments, LP Chile will also be required to maintain a ratio of net debt to earnings before interest, taxes, depreciation and amortization (EBITDA) of less than or equal to 2.5 and a ratio of EBITDA to financial costs of at least 3. The loan agreement also contains customary events of default, the occurrence of which could result in acceleration of our obligations to repay the indebtedness outstanding thereunder. Since this loan is denominated in other than U.S. dollars, the balance fluctuates based upon changes in the underlying currency rates. LP made payments of $21.0 million during the year which included a scheduled payment of $2.6 million and an optional prepayment of $18.4 million. The impact of foreign currency exchange rates in 2013 was $2.8 million which was partially offset by a UF change of $0.3 million. LP made principal payments of $5.5 million during 2012 which was partially offset by a UF change of $1.0 million plus the impact of foreign currency exchange rates of $3.2 million.

OTHER LIQUIDITY MATTERS

As of December 31, 2013, we had $3.7 million ($23.4 million, par value) of principal invested in auction rate securities (ARS). The ARS held by us are securities with long-term nominal maturities for which the interest rates were historically reset through a Dutch auction each month.

We review our marketable securities routinely for other-than-temporary impairment. The primary factors LP uses to determine if an impairment charge must be recorded because a decline in value of the security is other-than-temporary include (i) whether the fair value of the investment is significantly below its cost basis, (ii) the financial condition of the issuer of the security (including its credit rating), (iii) the length of time that the cost of the security has exceeded its fair value and (iv) LP’s intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in market value.

During 2011, we sold $38.1 million (par value) of our ARS for $19.1 million plus accrued interest. In connection with this transaction, we recorded a gain on sale of securities of $15.2 million, which represents a recovery of losses previously recorded as an Other-than-temporary impairment.

The estimated market value of our ARS holdings at December 31, 2013 was $3.7 million, which reflects a $19.7 million adjustment to the par value of $23.4 million. We intend to continue to offer our ARS at auction and to consider other options, including alternative buyers and other potential transactions. We do not currently require our ARS to be liquidated in order to fund our day-to-day operations and we are prepared to hold them until maturity, if necessary.

If uncertainties in the credit and capital markets continue, these markets deteriorate further or we experience any ratings downgrades on any investments in our portfolio (including on ARS), we may incur additional impairments to our investment portfolio, which could negatively affect our financial condition, results of operations and cash flow.

Contingency Reserves

Contingency reserves, which represent an estimate of future cash needs for various contingencies (principally, payments for environmental reserves), totaled $15.3 million at December 31, 2013, of which $2.0 million is estimated to be payable within one year. As with all accounting estimates, there is inherent uncertainty concerning the reliability and precision of such estimates. As described above and in Note 18 of the Notes to the consolidated financial statements included in item 8 of this report, the amounts ultimately paid in resolving these contingencies could exceed the current reserves by a material amount.

Contractual Obligations

The table below summarizes our contractual obligations as of December 31, 2013 over the next several years. See discussion above concerning provisions that could accelerate the due dates on our long-term debt.

_______________

¹  Includes expected interest payments as well as debt maturities.

²  The majority of our purchase obligations are take-or-pay contracts made in the ordinary course of business related to raw materials and utility contracts. Other significant items included in the above table reflect purchase

42

obligations related to legally binding commitments for capital projects. Purchase orders made in the ordinary course of business are excluded from the above table and are cancelable without significant penalty.

³  Represents other long-term liability amounts reflected in our consolidated balance sheet that have known payment streams including items such as pension contributions. Current pension funding regulations required LP to contribute $2 - $5 million in 2014 to its defined benefit pension plans, and we have included $5 million in the table above. Future years are not estimable due to the large number of factors involved in determining minimum pension funding.

⁴  Uncertain tax positions have been excluded from the above table as it is not reasonably possible to estimate when these may need to be paid. As of December 31, 2013, the amount of uncertain tax positions excluded from the above table is $48.9 million.

⁵  As of December 31, 2013, LP estimates that capital expenditures of $3 million to $13 million will be required over the next six years to comply with the EPS's Clean Air Act. These have been excluded from the above table as it is not reasonably possible to determine when these may need to be paid.

⁶  As of December 31, 2013, the fair value of the continent consideration payable in connection with a business combination was $3.8 million. The fair value of this liability is remeasured at the end of each reporting period and has been excluded from the above table as it is not reasonably possible to determine the final liability.

⁷  As of December 31, 2013, LP had warranty reserves of $29.3 million. These have been excluded from the above table as it is not reasonably possible to determine when these may need to be paid.

Other Financing Arrangements

In connection with the sale of southern timber and timberlands in 2003, we received $26 million in cash and $410 million in notes receivable from the purchasers of such timber and timberlands. In order to borrow funds in a cost-effective manner, LP issued $368.7 million of senior debt in 2003 in a private placement to unrelated third parties. Both the notes receivable and notes payable mature in 2018. The notes payable are supported by a bank letter of credit. LP’s reimbursement obligations under the letter of credit are secured by the notes receivable. In general, the creditors under this arrangement have no recourse to LP’s assets, other than the notes receivable. However, under certain circumstances, LP may be liable for certain liabilities (including liabilities associated with the marketing or remarketing of the notes payable and reimbursement obligations, which are fully cash collateralized under the letter of credit supporting the notes payable) in an amount not to exceed 10% of the aggregate principal amount of the notes receivable. LP’s maximum exposure in this regard was approximately $41 million as of December 31, 2013 and December 31, 2012. The notes receivable are classified as long-term “Notes receivable from asset sales” and the notes payable are classified as long-term debt on the financial statements included in item 8 of this report.

In connection with the sales of timberlands in California in 1997 and 1998, we received notes from the purchasers totaling $403.8 million. The notes receivable were monetized through the issuance of notes payable in a private placement secured by the notes. Proceeds from the notes receivable from the purchasers are used to fund payments required for the notes payable. To date, all installments under these notes have been received when due and the corresponding installments under the notes payable have been paid when due. The next installment is due in 2018. The notes receivable are classified as "Current portion of Notes receivable from asset sales" and "Long-term notes receivable from asset sales” and the notes payable are classified as the "Current portion of limited recourse notes payable" and long-term debt on the financial statements included in item 8 of this report.

POTENTIAL IMPAIRMENTS

We continue to review several mills and investments for potential impairments. Management currently believes we have adequate support for the carrying value of each of these assets based upon the anticipated cash flows that result from our estimates of future demand, pricing and production costs assuming certain levels of planned capital expenditures. As of December 31, 2013, there were no indications of impairment for the asset grouping that included the company's indefinitely curtailed facilities. As of December 31, 2013, the fair values of LP's facilities that have not been indefinitely curtailed were substantially in excess of their carrying value, which supported the conclusion that no impairment is necessary for those facilities. However, if demand and pricing for the relevant products continues at levels significantly below cycle average demand and pricing, or should LP decide to

43

invest capital in alternative projects, it is possible that impairment charges will be required. See Note 3 of the Notes to the financial statements included in item 8 of this report for impairment charges recorded in the periods presented.

We also review from time to time possible dispositions of various assets in light of current and anticipated economic and industry conditions, our strategic plan and other relevant factors. Because a determination to dispose of particular assets can require management to make assumptions regarding the transaction structure of the disposition and to estimate the net sales proceeds, which may be less than previous estimates of undiscounted future net cash flows, we may be required to record impairment charges in connection with decisions to dispose of assets.

PROSPECTIVE ACCOUNTING PRONOUNCEMENTS

See Note 1 for discussion of prospective accounting pronouncements in the Notes to the consolidated financial statements included in item 8 of this report.

44

ITEM 7A.    Quantitative and Qualitative Disclosures about Market Risk

A portion of our outstanding debt bears interest at variable rates and accordingly is sensitive to changes in interest rates. Interest rate changes would result in gains or losses in the market value of our debt portfolio due to differences in market interest rates and the rates at the inception of the debt agreements. Offsetting the variable rate debt are variable rate notes receivable from asset sales. Based upon the balances of the variable rate notes receivable from asset sales and the variable rate debt at December 31, 2013, a 100 basis point interest change would impact pre-tax net income and cash flows by $0.4 million annually.

Our international operations have exposure to foreign currency rate risks, primarily due to fluctuations in the Canadian dollar, Brazilian real and the Chilean peso. Although we have in the past entered into foreign exchange contracts associated with certain of our indebtedness and may continue to enter into foreign exchange contracts associated with major equipment purchases to manage a portion of the foreign currency rate risk, we historically have not entered into material currency rate hedges with respect to our exposure from operations, although we may do so in the future.

Some of our products are sold as commodities and therefore sales prices fluctuate daily based on market factors over which we have little or no control. The most significant commodity product we sell is OSB. Based upon an assumed North America annual production capacity in the OSB segment of 5.8 billion square feet (3/8” basis) or 4.2 billion square feet (7/16” basis), a $1 change in the annual average price per thousand square feet on 7/16” basis would change annual pre-tax profits by approximately $4.2 million.

The fair value of the contingent consideration related to the Peace Valley OSB acquisition is remeasured at the end of each reporting period. During 2013, the fair value of the contingent consideration payable was remeasured and reduced by $20.5 million due to the decline in projected OSB prices in the near term as compared to the data of acquisition.

We historically have not entered into material commodity futures and swaps, although we may do so in the future.

ITEM 8.    Financial Statements and Supplementary Data

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Louisiana-Pacific Corporation

We have audited the accompanying consolidated balance sheets of Louisiana-Pacific Corporation and subsidiaries (the "Company") as of December 31, 2013 and 2012, and the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2013. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

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

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Louisiana-Pacific Corporation and subsidiaries as of December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2013, based on the criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2014 expressed an unqualified opinion on the Company's internal control over financial reporting.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Louisiana-Pacific Corporation and its subsidiaries (collectively LP or the Company) are principally engaged in the manufacture of building products. In addition to its U.S. operations, the Company also maintains manufacturing facilities in Canada, Chile and Brazil through foreign subsidiaries and a joint venture. The principal customers for the Company’s building products are retail home centers, manufactured housing producers, distributors and wholesalers in North America and South America, with sales to Asia, Australia and Europe.

See Note 26 below for further information regarding LP’s products and segments.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. See discussion of specific estimates in this Note under the headings “Asset Impairments,” and “Other Operating Credits and Charges, Net” and in the Notes entitled “Income Taxes,” “Retirement Plans and Postretirement Benefits,” “Stockholders’ Equity,” “Other Operating Credits and Charges, Net,” “Gain (Loss) on Sale of and Impairment of Long-Lived Assets, Net,” “Contingencies” and "Acquisition of Peace Valley OSB."

Consolidation

The consolidated financial statements include the accounts of LP and its majority-owned subsidiaries after elimination of intercompany transactions. The equity method of accounting is used for joint ventures and investments in associated companies over which LP has significant influence but does not have control. Significant influence is deemed to exist generally when the Company has an ownership interest in the voting stock of an investee of between 20 percent and 50 percent. LP’s equity in the income and losses of these investments is recorded in “Equity in loss of unconsolidated affiliates” on the Consolidated Statements of Income. See Note 8 for further discussion of these investments and advances. Where our ownership interest is less than 100 percent but more than 50 percent, the outside shareholders’ interests are shown as non-controlling interest. See Note 19 for further discussion of this investment.

LP consolidates a variable interest entity (VIE) when it has a controlling financial interest in the VIE and is thus determined to be the VIE's primary beneficiary. LP currently consolidates its interest in LP Pinewood which was established in 2003 in connection with the sale of LP's southern timberlands. LP has notes receivable of $410.0 million (see Note 6) and notes payable of $368.7 million (see Note 12) recorded in the balance sheet related to LP's interest in the VIE. For further information regarding the details of the relationship of the assets and liabilities and the recourse provisions of the consolidated VIE see Note 12.

LP also has a variable interest in its Abitibi-LP equity method investee but is not considered to be the primary beneficiary. See Note 8 for further information on this investment.

Earnings per Share

Basic earnings per share are based on the weighted-average number of shares of common stock outstanding. Diluted earnings per share are based upon the weighted-average number of shares of common stock outstanding plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. This method requires that the effect of potentially dilutive common stock equivalents (employee stock options, stock settled stock appreciation rights, incentive shares, performance shares and warrants) be excluded from the calculation of diluted earnings per share for the periods in which losses from continuing operations are reported because the effect is anti-dilutive. The following table sets forth the computation of basic and diluted earnings per share:

	Year ended December 31,
Dollar and share amounts in millions, except per share amounts	2013			2012			2011

Loss from discontinued operations	—			—			(0.04		)
Net income (loss) per share	$	1.23		$	0.20		$	(1.36	)

Stock options, warrants and stock settled stock appreciation rights (SSARs) related to approximately 2.3 million and 5.3 million common shares were considered not in-the-money for purposes of LP's earnings per share calculation for the years ended December 31, 2013 and 2012. Stock options, warrants and stock settled stock appreciation rights (SSARs) related to approximately 7.1 million common shares for the year ended December 31, 2011 were considered anti-dilutive for purposes of LP’s earnings per share calculation due to LP’s loss position in continuing operations.

Cash and Cash Equivalents

Cash and cash equivalents consist of money market investments with an initial maturity of three months or less. These investments are stated at cost, which approximates market value.

Investments

LP’s long-term investments are classified as available-for-sale and are reported at estimated fair value. LP may invest in securities including U.S. treasury notes, bank obligations, corporate obligations, auction rate securities and commercial paper. Under LP’s investment criteria at purchase, bank and corporate obligations carry a rating of at least A-1 and commercial paper must have the highest rating obtainable from one or more rating agencies. Unrealized gains and losses, net of tax, on these investments are reported as a separate component of “Accumulated

54

comprehensive loss” in Stockholders’ Equity until realized. Impairment losses are charged to income for other-than-temporary declines in fair value. Realized gains and losses (including impairments) are recorded in “Investment income” in the Consolidated Statements of Income. For purposes of computing realized gains and losses, cost is identified on a specific identification basis. See Note 2 for further discussion.

Fair Value of Financial Instruments

LP has, where appropriate, estimated the fair value of financial instruments. These fair value amounts may be significantly affected by the assumptions used, including the discount rate and estimates of cash flows. Accordingly, the estimates presented are not necessarily indicative of the amounts that could be realized in a current market exchange.

Inventory

Inventories are valued at the lower of cost or market. Inventory costs include materials, labor and operating overhead. The LIFO (last-in, first-out) method is used for a minor portion of the Company’s log inventories with the remaining inventories valued at FIFO (first-in, first-out) or average cost. See Note 5 for further discussion.

Timber and Timberlands

Timber and timberlands is comprised of timber deeds and allocations of purchase price to Canadian timber harvesting licenses. Timber deeds are transactions in which LP purchases timber, but not the underlying land. The cost of timber deeds are capitalized in timber and timberlands and charged to cost of timber harvested as the volume is removed. Timber that has been severed but has not yet been delivered to a facility is included in timber and timberlands. The values associated with timber licenses were allocated in the purchase price allocations for Le Groupe Forex (Forex), Peace Valley OSB and the assets of Evans Forest Products. These licenses have a life of twenty to twenty-five years. These licenses are amortized on a straight-line basis over the life of the facilities. Cost of timber harvested also includes the amortization of the timber licenses. See Note 7 for further discussion.

Assets Held for Sale

Over the last several years, LP has adopted and implemented plans to sell selected assets in order to improve its operating results. LP is required to classify assets held for sale which are not part of a discontinued business separately on the face of the financial statements outside of “Property, plant and equipment”. As of December 31, 2013 and 2012, LP included two OSB mills and various non-operating sites in its held for sale category. See Note 3 for discussion of impairments recorded on these assets to reduce carrying value to estimated sales prices less estimated selling costs. During 2013, assets held for sale of $14.9 million were reclassified to assets held and used, due to a change in the plan of sale. The 2012 disclosure below was updated to reflect this change. The current book values of assets held for sale by category is as follows:

Dollar amounts in millions	December 31,
	2013			2012
Property, plant and equipment, at cost:
Land, land improvements and logging roads, net of road amortization	$	6.9		$	7.1
Buildings	6.2			7.8
Machinery and equipment	99.1			99.7
	112.2			114.6
Accumulated depreciation	(95.9		)	(97.0		)
Net property, plant and equipment	$	16.3		$	17.6

LP believes that the net realizable sales value of the aforementioned assets exceeds their carrying values.

55

Property, Plant and Equipment

Property, plant and equipment, including capitalized interest, are recorded at cost. Depreciation for financial statement purposes is provided principally using the units of production method for machinery and equipment which amortizes the cost of equipment over the estimated units that will be produced during its useful life. Provisions for depreciation of buildings, land improvements and the remaining machinery and equipment have been computed using straight-line rates based on the estimated service lives. The effective straight-line lives for the principal classes of property range from three to twenty years.

Logging road construction costs are capitalized and included in land and land improvements. These costs are amortized as the timber volume adjacent to the road system is harvested.

LP capitalizes interest on borrowed funds during construction periods. Capitalized interest is charged to machinery and equipment accounts and amortized over the lives of the related assets. Capitalized interest totaled $1.6 million in 2013 and $0.2 million in 2012.

Potential Impairments

Long-lived assets to be held and used by LP (primarily property, plant and equipment and timber and timberlands) are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. When impairment is indicated, the book values of the assets are written down to their estimated fair value as calculated by the expected discounted cash flow or estimated net sales price. See Note 3 for impairment charges recorded in the periods presented. See Note 17 for a discussion of charges in 2013, 2012 and 2011 related to impairments of property, plant and equipment. Long-lived assets that are held for sale are written down to the estimated sales proceeds less cost to sell unless the estimated net proceeds exceed the carrying value.

LP continues to review certain operations and investments for potential impairments. LP’s management currently believes it has adequate support for the carrying value of each of these operations and investments based upon the anticipated cash flows that result from estimates of future demand, pricing and production costs assuming certain levels of planned capital expenditures. As of December 31, 2013, the fair values of LP's facilities were substantially in excess of their carrying value, which supported the conclusion that no impairment is necessary for those facilities. However, if demand and pricing for the relevant products continues at levels significantly below cycle average demand and pricing, or should LP decide to invest capital in alternative projects, it is possible that impairment charges will be required.

Income Taxes

LP accounts for income taxes under an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in LP’s financial statements or tax returns. In estimating future tax consequences, LP generally considers all expected future events other than the enactment of changes in tax laws or rates and future income. The effect on deferred tax assets and liabilities of a change in tax rates will be recognized as income or expense in the period that includes the enactment date. Additionally, deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion of the deferred tax assets will not be realized.

LP recognizes liabilities for uncertain tax positions through a two step process. The first step is to the evaluate the tax position for recognition by determining if the weight of the available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation process, if any. The second step requires LP to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as LP must determine the probability for various outcomes. LP evaluates these uncertain tax provisions when new information becomes available. These revaluations are based upon factors including, but not limited to, changes in circumstances, changes in tax law, successful settlement of issues under audit and new audit activity. Such a change in recognition or measurement could result in the recognition of a tax benefit or an increase to the related provision.

56

LP classifies interest related to income taxes liabilities or uncertain tax positions as interest expense or interest income and, if applicable, penalties are recognized as a component of income tax expense.

See Note 10 for further discussion of deferred taxes.

Stock-Based Compensation

LP recognizes the cost of employee services received in exchange for awards of equity instruments, such as stock options, performance shares, restricted stock or restricted stock units and stock settled stock appreciation rights (SSAR), based upon the fair value of those awards at the date of grant over the requisite service period. LP generally uses the Black-Scholes-Merton (Black-Scholes) option pricing model to determine the fair value of the stock option and SSAR awards. Stock-based compensation plans, related expenses and assumptions used in the Black-Scholes option pricing model are more fully described in Note 14. The fair market value of performance share awards are determined based on the fair value as of the date of grant times the number of shares adjusted for the weighted probability of the attainment of the relevant performance goals.

Derivative Financial Instruments

To reduce foreign currency exchange and interest rate risks, LP occasionally utilizes derivative financial instruments, which include forward exchange, options and futures contracts. For the years ended December 31, 2013, 2012 and 2011, LP did not enter into any material derivative financial contracts.

Foreign Currency Translation

The functional currency for the Company’s Canadian subsidiaries is the U.S. dollar; however the books and records for these subsidiaries are maintained in the Canadian dollar. The financial statements of these foreign subsidiaries are remeasured into U.S. dollars using the historical exchange rate for property, plant and equipment, timber and timberlands, goodwill, and certain other non-monetary assets and related depreciation and amortization on these assets and liabilities. LP uses the exchange rate at the balance sheet date for the remaining assets and liabilities, including deferred taxes. A weighted-average exchange rate is used for each period for revenues and expenses. These transaction gains or losses are recorded in “Other non-operating income (expense)” on the Consolidated Statements of Income.

The functional currencies of LP’s Chilean, Brazilian and Peruvian subsidiaries are the Chilean peso, Brazilian real and Peruvian nuevo sol and their books and records are maintained in the local currency. Translation adjustments, which are based upon the exchange rate at the balance sheet date for assets and liabilities and the weighted-average rate for the income statement, are recorded in “Accumulated comprehensive loss” in Stockholders’ equity.

Goodwill

Goodwill is tested for impairment on an annual basis, and when indicators of impairment are determined to exist. Impairment is evaluated by applying a fair value based test. Impairment losses would be recognized whenever the implied fair value of goodwill is less than its carrying value.

Intangible Assets

Intangible assets with finite useful lives are amortized generally on a straight-line basis over the periods benefited. Impairment of the intangible asset is evaluated when factors indicate impairment may exist.

Restricted Cash

In accordance with LP’s credit facilities, discussed at Note 12, LP has established restricted cash accounts. As of December 31, 2013, a portion of the restricted cash secures outstanding letters of credit under LP’s U.S. and Canadian credit facilities.

57

Revenue Recognition

Revenue is recognized when customers receive products and title has passed. The following criteria are used to determine that title has passed: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the price to the buyer is fixed or determinable; and (4) the collection is reasonably assured.

During 2013, 2012 and 2011, LP's top ten customers accounted for approximately 44%, 46% and 48% of its sales. During 2012, Home Depot, Inc. accounted for more than 10% of its sales with no customers exceeding 10% in 2013 or 2011.

Pricing and Sales Incentives

LP records estimated reductions to revenue for customer programs and incentive offerings, including pricing arrangements, promotions and other volume-based incentives, at the date revenue is recognized. Some of these incentives are negotiated up front with the customer and are redeemable only if the customer achieves a specified cumulative level of sales (measured in dollars or units) or sales increase. Under these incentive programs, at the time of sale, LP estimates the anticipated rebate to be paid based upon forecasted sales levels. These forecasts are updated on a regular basis. If the forecasted sales for a customer change significantly, the accrual for rebates is adjusted to reflect the revised estimate.

Asset Retirement Obligations

LP records the fair value of the legal obligations and the conditional obligations to retire and remove long-lived assets in the period which the obligation is incurred. These obligations primarily consist of monitoring costs on closed landfills, timber reforestation obligations associated with LP’s timber licenses in Canada and certain site restoration costs. When the related liability is initially recorded, LP capitalizes the cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its settlement value and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, LP recognizes a gain or loss for any difference between the settlement amount and the liability recorded. See Note 15 for further discussion.

Deferred Debt Costs

Deferred debt costs are amortized over the life of the related debt using a straight line basis which approximates the effective interest method. If the debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired to other non-operating income (expense). During 2013, $1.4 million and during 2012, $4.5 million of deferred debt costs were written off in association with the early debt extinguishment. LP amortized deferred debt costs of $1.4 million, $1.5 million and $2.6 million for the years ended December 31, 2013, 2012 and 2011. See Note 11 for further discussion.

Other Operating Credits and Charges, Net

LP classifies significant amounts that management considers unrelated to ongoing core operating activities as “Other operating credits and charges, net” in the Consolidated Statements of Income. Such items include, but are not limited to, amounts related to restructuring charges (including severance charges), charges to establish and maintain litigation or environmental reserves, product reserves, prior year inventory profit adjustments, retirement charges and gains or losses from settlements with governmental or other organizations. Due to the nature of these items, amounts in the income statement can fluctuate from year to year. The determination of which items are considered significant and unrelated to core operations is based upon management’s judgment. See Note 16 for a discussion of specific amounts in 2013, 2012 and 2011.

Retirement Benefits

LP is required to use actuarial methods and assumptions in the valuation of defined benefit obligations and the determination of expense. Difference between actual and expected results or changes in the values of the obligations

58

and plan assets are not recognized in earnings as they occur but, rather, systematically and gradually over subsequent periods. See Note 13 for further information.

Comprehensive Income

Comprehensive income consists of net income (loss) and other gains and losses affecting shareholders’ equity that are excluded from net income (loss), including foreign currency translation adjustments, prior service costs and credits, transition assets or obligations associated with pension or other post retirement benefits that have not been recognized as components of net periodic benefit costs, net unrealized gains or losses on securities, and unrealized gains and losses on financial instruments qualifying for cash flow hedge accounting, and is presented in the accompanying Consolidated Statements of Comprehensive Income. See Note 23 for further discussion.

Present and Prospective Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02 "Reporting of Amounts Reclassified Out of Accumulated Comprehensive Income." The amendment does not change the current requirement for reporting net income or other comprehensive income in financial statements; however, the amendment requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The new disclosure requirements were effective for all periods beginning after December 15, 2012. The adoption of the amendments impacts presentation only and did not have an effect on LP’s financial condition, results of operations or cash flows. See Note 23 for further discussion.

2. INVESTMENTS

Long-term investments held by LP are debt securities designated as available for sale and are reported at fair market value using the specific identification method. The following table summarizes unrealized gains and losses related to these investments as of December 31, 2013 and December 31, 2012:

Dollar amounts in millions	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Fair Value
December 31, 2013
Auction rate securities	$	0.4	$	3.3	$	—	$	3.7
Total marketable securities	$	0.4	$	3.3	$	—	$	3.7
December 31, 2012
Auction rate securities	$	0.3	$	1.7	$	—	$	2.0
Total marketable securities	$	0.3	$	1.7	$	—	$	2.0

As of December 31, 2013, LP had $3.7 million ($23.4 million, par value) invested in auction rate securities (ARS). The ARS held by LP are securities with long-term nominal maturities for which the interest rates may be reset through a Dutch auction each month. LP’s investments in ARS represent interests in collateralized debt obligations supported by pools of residential and commercial mortgages, bank trust preferred notes and other securities.

During 2011, LP sold $38.1 million (par value) of its ARS in an open market transaction for $19.1 million. LP recorded a gain on sale of securities of $15.2 million, which represents a recovery of losses previously recorded as an “Other-than-temporary impairment”.

LP reviews its marketable securities routinely for other-than-temporary impairment. The primary factors LP used to determine if an impairment charge must be recorded, because a decline in value of the security is other than temporary, include (i) whether the fair value of the investment is significantly below its cost basis, (ii) the financial condition of the issuer of the security (including its credit rating) and the underlying collateral, (iii) the length of

59

time that the cost of the security has exceeded its fair value and (iv) LP’s intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in market value.

The contractual maturities of debt securities classified as available for sale at December 31, 2013 were as follows:

Dollar amounts in millions	2013
	Amortized Cost		Fair Value
Due in one year or less	$	—	$	—
Due in more than one year	0.4		3.7
Total marketable securities	$	0.4	$	3.7

Proceeds from sales and maturities of investments for the year ended December 31, 2011, totaled $19.1 million. There were no purchases of short-term and long-term investments for the years ended December 31, 2013, 2012, and 2011. During 2013, 2012 and 2011, LP did not own any short-term investments. Net unrealized gains and losses on derivative instruments are reported as a separate component of “Accumulated comprehensive loss” in Stockholders’ equity.

During 2012, LP's ARS litigation with Deutsche Bank Securities, Inc. was settled, which resulted in a gain of $20.0 million recorded in non-operating income (expense). (See Note 11 for further discussion)

3. FAIR VALUE MEASUREMENTS

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. LP is required to classify these financial assets and liabilities into two groups: recurring—measured on a periodic basis and non-recurring—measured on an as needed basis.

There are three levels of inputs that may be used to measure fair value:

Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2 Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; or valuations based on models where the significant inputs are observable or can be corroborated by observable market data.

Level 3 Valuations based on models where significant inputs are not observable. Unobservable inputs are used when little or no market data is available and reflect the Company’s own assumptions about the assumptions market participants would use.

Assets and liabilities measured at fair value on a recurring basis as of December 31, 2013 and 2012 is summarized in the following tables.

Dollar amounts in millions	December 31, 2013		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Available for sale securities	$	3.7	$	—	$	—	$	3.7
Trading securities	2.0		2.0		—		—
Contingent consideration	3.8		—		—		3.8

60

Dollar amounts in millions	December 31, 2012		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Available for sale securities	$	2.0	$	—	$	—	$	2.0
Trading securities	1.7		1.7		—		—
Total	$	3.7	$	1.7	$	—	$	2.0

Due to the lack of observable market quotations on a portion of LP’s auction rate securities (ARS) portfolio, LP evaluates the structure of its ARS holdings and current market estimates of fair value, including fair value estimates from issuing banks that rely exclusively on Level 3 inputs. These inputs include those that are based on expected cash flow streams and collateral values, including assessments of counterparty credit quality, default risk underlying the security, discount rates and overall capital market liquidity. The valuation of LP’s ARS investment portfolio is subject to uncertainties that are difficult to predict. Factors that may impact LP’s valuation include changes to credit ratings of the securities as well as to the underlying assets supporting those securities, rates of default of the underlying assets, underlying collateral value, discount rates, counterparty risk and ongoing strength and quality of market credit and liquidity.

Trading securities consist of rabbi trust financial assets which are recorded in other assets in LP’s consolidated balance sheets. The rabbi trust holds assets attributable to the elections of certain management employees to defer the receipt of a portion of their compensation. The assets of the rabbi trust are invested in mutual funds and are reported at fair value based on active market quotations, which represent Level 1 inputs.

The following table summarizes changes in assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the twelve months ended December 31, 2013 and 2012.

Carrying amounts reported on the balance sheet for cash, cash equivalents, receivables and accounts payable approximate fair value due to the short-term maturity of these instruments.

LP reviews the carrying values of long-lived assets to be held and used for impairment wherever events or changes in circumstances indicate possible impairment. An impairment loss is recognized when a long-lived asset's carrying value is not recoverable (given assumptions on housing starts and growth rates) and exceeds estimated fair value.

During the year ended 2013, LP recognized a gain of $20.5 million as a fair value adjustment to the contingent consideration payable in connection with a business combination (see Note 24 for further discussion). The fair value of the contingent consideration was reduced during the year due to the decline in projected OSB prices as compared to the initial fair value which was established at the date of the acquisition. This reduction resulted in lowering the estimated payment obligation. The fair value adjustment is recorded in Other Operating Credits and Charges, Net

61

(see Note 16 for further discussion). This fair value was determined based upon the income approach using significant non-observable inputs such as projected OSB pricing taking into consideration volatility of such projections.

During the year ended 2012, LP recognized an impairment charge of $4.4 million on an OSB mill in Quebec, Canada, held for sale based upon a change in the plan for its sale and to reduce its carrying value to estimated selling price less selling costs of $15.0 million. The valuation of the affected assets was determined using level two inputs under the market approach. During 2013, this mill was reclassified to held and used.

During the year ended December 31, 2011, LP determined that an impairment review was required of its LSL facility located in Houlton, Maine due to continued operating losses which were driven by the significant reductions in current and forecasted housing starts. As a result of this review, LP recognized a pre-tax, non-cash impairment charge of $62.0 million. The estimated fair value of long-lived assets was calculated based on the income approach using the discounted probability of weighted cash flows taking into account current expectations for asset utilization, housing starts and the remaining useful life of related assets. In addition, liquidation values were considered where appropriate, as well as indicated values from divestiture activities. These assets are included in LP's property, plant and equipment (long-lived assets) which are held and used.

During the year ended December 31, 2011, LP recorded an impairment charge of $6.9 million on various assets held for sale to reduce their carrying value to the estimated sales price less estimated selling costs. The valuation of these assets was determined based upon level two inputs under the market approach. Also, LP recorded an impairment charge of $4.9 million on assets no longer used.

6. NOTES RECEIVABLE FROM ASSET SALES

Notes receivable from asset sales are related to transactions that occurred during 1997, 1998 and 2003. The 1997 and 1998 notes receivable provide collateral for LP’s limited recourse notes payable and the 2003 notes receivable provide collateral for LP’s non-recourse notes payable (see Note 12). LP monitors the collectability of these notes on a regular basis.

Dollar amounts in millions	Interest  Rate 2013		December 31,
			2013		2012
Notes receivable (secured), maturing 2018, interest rates fixed	7.3	%	22.2		113.6

Total			432.2		523.6
Current portion			—		91.4
Long-term portion			$	432.2	$	432.2

The weighted average interest rate for all notes receivable from asset sales at December 31, 2013 and 2012 was approximately 0.8% and 2.0%. The remaining notes of $432.2 million mature in 2018. LP estimates that the fair value of these notes at December 31, 2013 and 2012 was approximately $438.0 million and $531.9 million.

7. GOODWILL AND OTHER INTANGIBLE ASSETS

Changes in goodwill for the year ended December 31, 2013 are provided in the following table:

Dollar amounts in millions	2013

8. INVESTMENTS IN AND ADVANCES TO AFFILIATES

At December 31, 2013, LP has an investment in a joint venture with Resolute Forest Products (formerly Abitibi-Bowater) to operate jointly owned I-Joist facilities in Quebec. Each partner owns 50% of the venture. In 2013, LP acquired full ownership of the Peace Valley OSB joint venture (formerly referred to as Canfor-LP) in which LP previously maintained a 50% interest (see Note 24 for further information). Additionally, during 2013, LP sold its equity investment in U.S. Greenfiber, which resulted in a gain of $1.2 million.

The remaining investment does not meet the Regulation S-X significance test requiring the inclusion of the separate investee financial statements; however based upon the aggregation requirements under S-X, aggregated summarized financial information (including net sales and net income information for entities no longer held) is required as follows:

	Year ended December 31,
Dollar amounts in millions	2013		2012		2011
Net sales	$	230.5	$	238.9	$	188.6
Net income (loss)	$	23.8	$	3.4	$	(53.7	)

Total liabilities	$	10.0	$	41.4
Equity	6.4		159.9
Total liabilities and equity	$	16.4	$	201.3

LP sells products and raw materials and purchases products for resale from Abitibi-LP and previously purchased OSB from Canfor - LP prior to the acquisition on May 31, 2013. LP eliminates profits on these sales and purchases, to the extent the inventory has not been sold through to third parties, on the basis of its 50% interests. For the years ended December 31, 2013, 2012 and 2011, LP sold $13.7 million, $8.7 million and $6.0 million of products to Abitibi-LP and purchased $52.0 million, $37.9 million and $33.6 million of I-joists from Abitibi-LP. LP purchased $98.2 million, $148.0 million and $92.9 million from Canfor-LP during the years ended December 31, 2013, 2012 and 2011. Included in LP’s Consolidated Balance Sheets at December 31, 2013 and 2012 are $0.8 million and $1.4 million in accounts receivable and $6.7 million in accounts payable for 2012 from from these affiliates.

64

During the year ended December 31, 2011, LP was required to record an other than temporary impairment of its equity investment in U.S. Greenfiber as LP's current book value exceed the enterprise (fair) value of the investment by $14.8 million.

9. ACCOUNTS PAYABLE AND ACCRUED LIABILITIES

Additionally, included in accounts payable is $6.4 million related to capital expenditures that had not yet been paid as of December 31, 2013.

10. INCOME TAXES

Income (loss) from continuing operations before income taxes consists of the following:

	Year ended December 31,
Dollar amounts in millions	2013		2012		2011
Domestic	$	134.0	$	31.0	$	(155.0	)
Foreign	84.5		5.5		(61.6		)
Total	$	218.5	$	36.5	$	(216.6	)

65

The following presents the components of LP’s income tax provision (benefit) from continuing operations.

	Year ended December 31,
Dollar amounts in millions	2013			2012			2011
Current tax provision (benefit):
U.S. federal	$	1.3		$	12.6		$	(2.9	)
State and local	1.2			0.6			(1.3		)
Foreign	3.3			0.9			(8.6		)
Net current tax provision (benefit)	5.8			14.1			(12.8		)
Deferred tax provision (benefit):
U.S. federal	44.6			(7.3		)	(39.7		)
State and local	2.5			—			(6.1		)
Foreign	13.4			(0.3		)	(11.4		)
Net valuation allowance increase (decrease)	(25.2		)	0.5			28.9
Net deferred tax benefit	35.3			(7.1		)	(28.3		)
Total income tax provision (benefit)	$	41.1		$	7.0		$	(41.1	)

LP received income tax refunds during 2013, 2012 and 2011 of $0.9 million, $1.9 million and $25.8 million and paid cash taxes of $6.8 million, $1.6 million and $0.8 million. Included in the Consolidated Balance Sheet at December 31, 2013 and 2012 are income tax receivables of $1.2 million and $1.8 million.

The income tax effects of LP’s share of the income or loss of U.S. GreenFiber and Canfor-LP OSB Limited Partnership in 2013, 2012 and 2011 are recorded in “Provision (benefit) for income taxes” on the Consolidated Statements of Income, while LP’s share of such pre-tax income is recorded in “Equity in (income) loss of unconsolidated affiliates”.

66

The tax effects of significant temporary differences creating deferred tax (assets) and liabilities at December 31 were as follows:

	December 31,
Dollar amounts in millions	2013			2012
Property, plant and equipment	$	178.9		$	148.5
Timber and timberlands	10.5			10.4
Inventories	(8.1		)	(6.9		)
Accrued liabilities	(70.0		)	(78.9		)
Benefit of capital loss and NOL carryovers	(97.1		)	(187.0		)
Benefit of federal & state tax credit carryovers	(14.9		)	(13.2		)
Installment sale gain deferral	129.9			163.0
Market value write down of ARS	(8.9		)	(8.9		)
Other	(6.0		)	(1.4		)
Valuation allowance	23.5			50.7
Net deferred tax liabilities	$	137.8		$	76.3
Balance sheet classification
Current deferred tax asset	$	(50.9	)	$	(12.3	)
Long-term deferred tax asset	—			(5.0		)
Long-term deferred tax liability	188.7			93.6
	$	137.8		$	76.3

The $97.1 million of benefit relating to capital loss and net operating loss (NOL) carryovers included in the above table at December 31, 2013 consists of $3.4 million for federal NOL carryovers which will begin to expire in 2031, $30.5 million (net of federal taxes) for state NOL carryovers and $0.8 million for state capital losses which will expire in various years 2014 through 2032, $50.5 million for Canadian NOL carryovers which will expire starting in 2029 and $11.9 million for Canadian capital loss carryovers which may be carried forward indefinitely. At December 31, 2013, LP has recorded valuation allowances of $8.8 million related to state NOL carryover benefit; $0.8 million related to state capital loss carryover; $11.9 million against the Canadian capital loss benefit; $0.9 million against the state tax credit carryovers and $1.1 million related to other items.

LP periodically reviews the need for valuation allowances against deferred tax assets and recognizes these deferred tax assets to the extent that their realization is more likely than not. As part of our review, we consider all positive and negative evidence, including earnings history, the future reversal of deferred tax liabilities, and the relevant expirations of carry forwards. In 2013 we reversed the valuation allowance that had been previously recorded primarily against our state and Canadian deferred tax assets by approximately $22.1 million based on current operating results and an increase in deferred tax liabilities. Additionally, in the fourth quarter we reduced the valuation allowance by $5.1 million based on recent positive earnings history and trends and generally improving economic conditions. If future years’ earnings differs from the estimates used to establish these valuation allowances, LP may be required to record an adjustment resulting in an impact on tax expense (benefit) for that period.

As a result of certain realization requirements of ASC 718 Compensation --Stock Compensation, the table of deferred tax assets and liabilities shown above does not include $13.2 million and $3.7 million of deferred tax assets as of December 31, 2013 and December 31, 2012 that arose directly from tax deductions related to amounts of equity compensation that are greater than the compensation recognized for financial reporting. Equity will be increased if and when such deferred tax assets are ultimately realized. LP uses the "with and without" method for determining when excess tax benefits have been realized. In 2013 and 2011, LP recognized a current tax benefit of $0.3 million and a current tax cost of $0.6 million as adjustments to additional paid in capital arising from tax deductions for equity compensation that were more or less than the compensation recognized for financial reporting.

67

U.S. taxes have not been provided on approximately $47.2 million of undistributed earnings of LP’s foreign subsidiaries, which under existing law are not subject to U.S. tax until distributed as dividends. These earnings have been, and are intended to be, indefinitely reinvested in LP’s foreign operations. Determination of the amount of any unrecognized income tax liability on this temporary difference is not practical because of the complexities of the hypothetical calculation. Furthermore, any taxes paid to the foreign governments on these earnings may be used, in whole or in part, as credits against the U.S. tax on any dividends distributed from such earnings.

The following table summarizes the differences between the statutory U.S. federal and effective income tax rates on continuing operations:

	Year ended December 31,
	2013		2012		2011
U.S. Federal tax rate	35	%	35	%	(35	)%
State and local income taxes	2		2		(3	)
Adjustments to previously recorded deferred tax liabilities	—		(12	)	—
Uncertain tax positions	—		(1	)	5
Effect of foreign tax rates	(3	)	(1	)	2
Effect of foreign exchange on functional currencies	(3	)	(2	)	(2	)
Valuation allowance	(12	)	1		13
Other, net	—		(3	)	1
Effective tax rate (%)	19	%	19	%	(19	)%

LP and its domestic subsidiaries are subject to U.S. federal income tax as well as income taxes of multiple state jurisdictions. Its foreign subsidiaries are subject to income tax in Canada, Chile, Peru and Brazil. During 2011, the U.S. Internal Revenue Service initiated an audit of tax years 2007 through 2009 for which field work has been completed. LP has protested certain proposed adjustments and requested review by the IRS Appeals Office. During 2013, LP deposited $17.1 million with the IRS to suspend the accrual of interest pending the resolution of this matter. The deposit is included within Other assets on the Consolidated Balance Sheet. All U.S. federal audits of prior years have been completed. During 2013, LP settled all of its open state income tax audits and remains subject to various state and local income tax examinations for the tax years 2007 through 2012. Canadian federal income tax years are closed 2008 and no examinations are currently in progress. Quebec provincial audits have been effectively settled through 2011 and 2012 is currently under review. During 2012, the Chilean Tax Office initiated an audit of the 2011 tax year.

On September 13, 2013, the U.S. Treasury Department and the IRS issued final regulations that address costs incurred in acquiring, producing, or improving tangible property (the "tangible property regulations"). The tangible property regulations are generally effective for tax years beginning on or after January 1, 2014, and may be adopted in earlier years.  We have considered the effect of these tax law changes to our deferred tax assets and liabilities and do not expect their implementation to have a material impact on our consolidated financial statements.

In accordance with the accounting for uncertain tax positions, the following is a tabular reconciliation of the total amount of unrecognized tax benefits at the beginning and end of the years presented:

	December 31,
Dollar amounts in millions	2013			2012			2011
Beginning balance	$	49.9		$	23.5		$	11.3
Increases:
Tax positions taken in current year	—			0.1			—
Tax positions taken in prior years	0.4			33.9			12.9
Decreases:
Tax positions taken in current year	—			—			(0.3		)
Tax positions taken in prior years	—			(7.4		)	(0.2		)
Settlements during the year	—			(0.2		)	(0.2		)
Lapse of statute in current year	(1.4		)	—			—
Ending balance	$	48.9		$	49.9		$	23.5

Included in the above balances at December 31, 2013 and 2012 is $12.8 million and $11.9 million of tax benefits that, if recognized, would affect LP’s effective tax rate. LP accrued interest of $0.2 million and $1.8 million during 2013 and 2012, and in total LP has recognized a liability of $5.7 million and $5.5 million for accrued interest related to its uncertain tax positions as of December 31, 2013 and 2012. LP's conference with the IRS Appeals office is scheduled for the first half of 2014. While outcomes and timing cannot be predicted, it is possible that unrecognized tax benefits of up to $42.8 million, primarily related to the timing of fixed asset recovery, could change significantly as a result of these conferences during the next twelve months.

11. NON-OPERATING INCOME (EXPENSE)

Included in LP’s Consolidated Statements of Income is non-operating income of $3.8 million for the year ended December 31, 2013, and non-operating expense of $69.4 million and $44.0 million for the years ended December 31, 2012 and 2011. This income (expense) is comprised of the following components:

Total non-operating income (expense)	$	3.8		$	(69.4	)	$	(44.0	)

For the year ended December 31, 2013, LP recognized a gain of $35.9 million from the acquisition of the remaining 50% ownership of the Peace Valley OSB joint venture and a gain of $1.2 million from the sale of the U.S. GreenFiber joint venture.

For the year ended December 31, 2012, LP recognized a gain of $20.0 million from the settlement of its ARS litigation with Deutsche Bank Securities, Inc.

For the year ended December 31, 2011 , LP recorded an impairment charge of $14.8 million associated with an equity investment in a joint venture to reduce the carrying value of this investment to it estimated fair value. See Note 3 for further discussion of this impairment and Note 8 for discussion of the investment.

12. LONG-TERM DEBT

	Interest Rate  2013		December 31,
Dollar amounts in millions			2013			2012
Debentures:
Senior unsecured notes, maturing 2020, interest rates fixed	7.5	%	$	350.0		$	350.0
Bank credit facilities:
Chilean term credit facility, maturing 2019, interest rates fixed	UF+3.9%		15.7			39.3

Total			765.0			880.5
Less: current portion			(2.3		)	(97.8		)
Net long-term portion			$	762.7		$	782.7

LP believes the carrying amounts of its variable rate long-term debt approximates fair market value. LP estimated the limited recourse notes payable to have a fair value of approximately $23 million and $114 million at December 31, 2013 and 2012. LP estimated the senior unsecured notes maturing in 2020 to have a fair value of $390 million at December 31, 2013 and $397 million at December 31, 2012 based upon market quotations. LP believes the carrying amounts of the Chilean term credit facility as well as the Brazil export facility approximates fair market value based upon current interest rates with similar remaining maturities.

LP issued $348.6 million of senior notes in June 1998 in a private placement to institutional investors. The remaining $22.0 million of notes mature in 2018. A principal payment of $90.0 million was made on the notes during 2013. The notes are secured by $22.2 million of notes receivable from Green Diamond Resource Company (Green Diamond). Pursuant to the terms of the notes payable, in the event of a default by Green Diamond, LP would be liable to pay only 10% of the indebtedness represented by the notes payable.

LP issued $368.7 million of non-recourse notes in 2003 in a private placement to unrelated third parties. The notes mature in 2018. The notes are supported by a bank letter of credit. LP’s reimbursement obligations under the letter of credit are secured by $410.0 million in notes receivable from assets sales. In general, the creditors under this arrangement have no recourse to LP’s assets, other than the notes receivable. However, under certain circumstances, LP may be liable for certain liabilities (including liabilities associated with the marketing or remarketing of the notes payable and reimbursement obligations, which are fully cash collateralized, under the letter of credit supporting the notes payable) in an amount not to exceed 10% of the aggregate principle amount of the notes receivable.

In December 2013, LP entered into a credit agreement with various lenders and American AgCredit, PCA, as administrative agent and CoBank, ACB, as letter of credit issuer. The credit agreement provides for a $200 million revolving credit facility, with a $60 million sublimit for letters of credit. The credit facility terminates and all loans made under the credit agreement become due in December 2018. As of December 31, 2013, no revolving borrowings had been made under the credit facility.

Certain of LP’s existing and future wholly owned domestic subsidiaries guaranty LP’s obligations under the credit facility. Subject to certain limited exceptions, obligations under the credit facility are secured by a lien on substantially all of the personal property of LP and its subsidiaries that are guarantors under the credit facility.

Revolving borrowings under the credit agreement accrue interest, at the Company’s option, at either a “base rate” plus a margin of 0.75% to 2.50% or LIBOR plus a margin of 1.75% to 3.50%. The credit agreement also includes an unused commitment fee, due quarterly, ranging from 0.30% to 0.625%. The applicable margins and fees within these ranges are based on the Company’s ratio of consolidated EBITDA to cash interest charges. The “base rate” is the highest of (i) the Federal funds rate plus 0.5%, (b) the U.S. prime rate, and (iii) one month LIBOR plus 1.0%.

71

The credit agreement contains various restrictive covenants and customary events of default. The credit agreement also contains financial covenants that require the Company and its consolidated subsidiaries to have, as of the end of each quarter, (i) a capitalization ratio (i.e., funded debt to total capitalization) of no more than 40% and (ii) unrestricted cash and cash equivalents of at least (a) $350,000,000 until closing of the the Company’s acquisition of Ainsworth Lumber Co. Ltd. and (b) $250,000,000 thereafter, in each case calculated in the manner specified in the credit agreement. As of December 31, 2013, we were in compliance with all financial covenants under the credit agreement.

In December 2009, LP Chile entered into a term loan agreement with Banco de Credito e Inversiones for UF 943,543.7391 (equivalent to $39 million at the time of inception). The loan will be repaid in 16 semi-annual principal payments that began in June 2012 and end in December 2019. The loan bears interest at UF plus 3.90% per annum, and is partially secured by a first priority security interest in substantially all of the real property owned by LP Chile. The loan contains various restrictive covenants and requires the maintenance by LP Chile of a debt to equity ratio of less than or equal to 1. If LP Chile is late in making payments, it will also be required to maintain a ratio of net debt to earnings before interest, taxes, depreciation and amortization (EBITDA) of less than or equal to 2.5 and a ratio of EBITDA to financial costs of at least 3. The loan agreement also contains customary events of default, the occurrence of which could result in acceleration of LP’s obligations to repay the indebtedness outstanding. Any increases or decreases in the loan balance shown are related to the change in the underlying foreign currency exchange rates, the UF or principal payments. LP made principal payments of $21.0 million during 2013 which included a scheduled payment of $2.6 million and an optional prepayment of $18.4 million. The impact of foreign currency exchange rates in 2013 was $2.8 million which was offset by a UF change of $0.3 million. LP made principal payments of $5.5 million during 2012 which was offset by a UF change of $1.0 million plus the impact of foreign currency exchange rates of $3.2 million.

In August 2011, LP entered into an export financing loan agreement with a Brazilian bank. This loan is to be repaid in 10 equal semi-annual payments that began in January 2013 and end in July 2017. During 2013, LP made principal payments of $2.0 million.

In May 2012, LP issued $350.0 million of 7.5% Senior Notes due 2020. LP used a portion of the proceeds to fully retire the remaining balance outstanding on the Senior Secured Notes due in 2017. In connection with this repurchase, LP recorded a loss on early debt extinguishment of $52.2 million which included $4.5 million associated with the unamortized financing costs associated with the Senior Secured Notes. On or after June 1, 2016, LP may, at its option on one or more occasions, redeem all or any portion of the Notes at specified redemption rates.

Obligations under the indenture governing LP's Senior Notes due 2020 are unsecured and not presently guaranteed by any of its subsidiaries. The indenture contains customary covenants applicable to LP and its subsidiaries, other than certain unrestricted subsidiaries, including restrictions on actions and activities that are restricted under the credit facility. The indenture also contains customary events of default, the occurrence of which could result in acceleration of LP's obligations to repay the indebtedness outstanding thereunder.

The weighted average interest rate for all long-term debt at December 31, 2013 and 2012 was approximately 3.9 percent and 4.2 percent. Required repayment of principal for long-term debt is as follows:

13. RETIREMENT PLANS AND POSTRETIREMENT BENEFITS

LP sponsors various defined benefit and defined contribution retirement plans that provide retirement benefits to substantially all of its employees. Most regularly scheduled employees are eligible to participate in these plans except those covered by a collective bargaining agreement, unless the collective bargaining agreement specifically allows for participation in LP’s plans. LP contributes to a multiemployer plan for certain employees covered by collective bargaining agreements. LP also provides other post retirement benefits consisting primarily of healthcare benefits to certain retirees who meet age and service requirements.

Defined Benefit Plans

Pension benefits are earned generally based upon years of service and compensation during active employment. Contributions to the qualified defined benefit pension plans are based on actuarial calculations of amounts to cover current service costs and amortization of prior service costs over periods ranging up to 20 years. LP contributes additional funds as necessary to maintain desired funding levels.

Benefit accruals under our most significant plans, which account for approximately 80% of the assets and 82% of the benefit obligations in the tables below, had been credited at the rate of 4% of eligible compensation with an interest credit based upon the 30-year U.S. Treasury rate. The Company discontinued providing contribution credits effective January 1, 2010 to these plans. The remaining defined benefit pension plans (primarily in Canada) use a variety of benefit formulas.

LP also maintains a Supplemental Executive Retirement Plan (SERP), an unfunded, non-qualified defined benefit plan intended to provide supplemental retirement benefits to key executives. Benefits are generally based on compensation in the years immediately preceding normal retirement. LP has established a grantor trust that provides funds for the benefits payable under the SERP. The assets of the grantor trust are invested in corporate-owned life insurance policies. At December 31, 2013 and 2012, the trust assets were valued at $9.7 million and $8.8 million and are included in “Other assets” on the Consolidated Balance Sheets. LP did not contribute to this trust in 2013 or 2012. During the year ended December 31, 2012, LP paid its retiring CEO his accumulated SERP liability of $10.4 million through the use of the assets included in the grantor trust. In connection with this distribution, LP recorded a plan settlement charge of $2.2 million.

Foreign exchange rate changes	0.2			—			(0.1		)
Total recognized in OCI	$	(43.3	)	$	2.2		$	38.2

LP calculates the net periodic pension cost for a given fiscal year based upon assumptions developed at the end of the previous fiscal year. As of January 1, 2010 LP froze future contribution credits a to its qualified U.S. defined benefit pension plans. LP recognized settlement charges of $2.2 million during 2012, related to the LP SERP pension plan associated with the retirement of LP's previous CEO.

The expected long-term rate of return on plan assets reflects the weighted-average expected long-term rates of return for the broad categories of investments currently held in the plans (adjusted for expected changes), based on historical rates of return for each broad category, as well as factors that may constrain or enhance returns in the broad categories in the future. The expected long-term rate of return on plan assets is adjusted when there are fundamental changes in expected returns in one or more broad asset categories and when the weighted-average mix of assets in the plans changes significantly.

The total accumulated benefit obligation for all pension plans as of December 31, 2013 and 2012 was $317.7 million and $346.0 million.

The accumulated benefit obligation and fair value of plan assets for pension plans with accumulated benefit obligations in excess of plan assets were $304.7 million and $256.7 million at December 31, 2013 and $331.7 million and $244.6 million at December 31, 2012. The projected benefit obligations and fair value of plan assets of plans with projected benefit obligations in excess of plan assets were $309.0 million and $256.7 million at December 31, 2013 and $337.7 million and $244.6 million at December 31, 2012.

The amounts of accumulated other comprehensive income that is expected to be amortized as expense during 2014 is:

Dollar amounts in millions
Net actuarial loss	$	5.6
Prior service cost	—
Total	$	5.6

LP expects to contribute $2.0 million to $5.0 million to its pension plans in 2014.

The benefits expected to be paid from the benefit plans, which reflect expected future service, are as follows:

Dollar amounts in millions
Year
2014	$	18.8
2015	19.4
2016	28.3
2017	22.8

2019 – 2023	108.9

These estimated benefit payments are based upon assumptions about future events. Actual benefit payments may vary significantly from these estimates.

Asset allocation targets are established based upon the long-term returns and volatility characteristics of the investment classes and recognize the benefits of diversification and the profits of the plans’ liabilities. The actual and target allocations at the measurement dates are as follows:

	Target Allocation 2013		Actual Allocation
			2013		2012
Asset category
Equity securities	49.1	%	46.4	%	36.4	%
Debt securities	24.9		36.8		37.8
Real estate	8.0		6.2		5.8
Other, including cash and cash equivalents	18.0		10.6		20.0
Total	100.0	%	100.0	%	100.0	%

LP’s investment policies for the defined benefit pension plans provide target asset allocations by broad categories of investment and ranges of acceptable allocations. These policies are set by an administrative committee with the goal of maximizing long-term investment returns within acceptable levels of volatility and risk. LP’s U.S. plans include real estate, hedge funds and real return investment strategies to increase returns and reduce volatility. LP’s plans do not currently invest directly in derivative securities, although such investments may be considered in the future to increase returns and/or reduce volatility. To the extent the expected return on plan assets varies from the actual return, an actuarial gain or loss results.

The fair value of LP’s pension plan assets at December 31, 2013 and December 31, 2012, fair value asset categories and the level of inputs as defined in Note 3 are as follows:

Level 1 investments are valued based on active market quotations.

Level 2 investments are valued based on the unit prices quoted by the funds, representing the fair value of underlying investments.

Due to the lack of observable market quotations on real estate and multi-strategy funds, LP evaluates their structure and current market estimates of fair value, including fair value estimates from the funds that rely exclusively on Level 3 inputs. These inputs include those that are based on expected cash flow streams and property values, including assessments of overall market liquidity. The valuations are subject to uncertainties that are difficult to predict.

Defined Contribution Plans

LP also sponsors defined contribution plans in the U.S. and Canada. In the U.S., these plans are primarily 401(k) plans for hourly and salaried employees that allow for pre-tax employee deferrals and a company match of up to 3.5% of an employee’s eligible wages (subject to certain limits). Under the profit sharing feature of these plans, LP may elect to contribute a discretionary amount as a percentage of eligible wages. Included in the assets of the 401(k) and profit sharing plans are 2.6 million shares of LP common stock that represented approximately 15.4% of the total market value of plan assets at December 31, 2013.

In Canada, LP sponsors both defined contribution plans and Registered Retirement Savings Plans for hourly and salaried employees that allow for pre-tax employee deferrals. LP provides a base contribution of 2.5% of eligible earnings and matches 50% of an employee’s deferrals up to a maximum of 3% of each employee’s eligible earnings (subject to certain limits).

Expenses related to defined contribution plans and the multiemployer plan in 2013, 2012 and 2011 were $8.3 million, $5.2 million and $5.5 million.

Other Benefit Plans

LP has several plans that provide postretirement benefits other than pensions, primarily for salaried employees in the U.S. and certain groups of Canadian employees. The funded status at December 31, 2013 and 2012 was $8.2 million and $9.7 million. Net expense related to these plans was not significant in 2013 or 2012.

Effective August 16, 2004, LP adopted the Louisiana-Pacific Corporation 2004 Executive Deferred Compensation Plan (the Plan). Pursuant to the Plan, certain management employees are eligible to defer up to 90% of their regular salary and annual cash incentives that exceed the limitation as set forth by the Internal Revenue Service. Each plan participant is fully vested in all employee deferred compensation and earnings credited associated with employee contributions. Employer contributions and associated earnings vest over periods not exceeding five years. The liability under this plan amounted to $1.9 million and $1.5 million at December 31, 2013 and December 31, 2012 and is included in “Other long-term liabilities” on LP’s Consolidated Balance Sheets.

14.    STOCKHOLDERS' EQUITY

Preferred Stock

The Company is authorized to issue up to 15,000,000 shares of preferred stock at $1.00 par value. At December 31, 2013, no shares of preferred stock have been issued; however, 2,000,000 shares of Series A Junior

79

Participating Preferred Stock have been reserved for issuance in connection with the Company’s Shareholder Rights Plan. Additional series of preferred stock may be designated and the related rights and preferences fixed by action of the Board of Directors.

Shareholder Rights Plan

In May 2008, the Board of Directors approved a shareholder rights plan and declared a dividend of one preferred share purchase right for each outstanding share of common stock. Each right represents the right to purchase one-hundredth of a share of Preferred Stock, at an exercise price of $100.00, subject to adjustment. The rights are only exercisable ten days after a person or group acquires, or commences a tender or exchange offer to acquire, beneficial ownership of 15% or more of the Company’s outstanding common stock.

Subject to the terms of the shareholder rights plan and the discretion of the Board of Directors, each right would entitle the holder to purchase a number of additional shares of common stock of LP having a total market value of twice the exercise price of each right. The rights expire in June 2018, but can be redeemed by action of the Board of Directors prior to that time at $0.01 per right.

Warrants

During 2009, LP issued warrants to purchase 18,395,963 shares of LP common stock at an exercise price of $1.39 per share subject to mandatory cashless exercise provisions. During the years ended December 31, 2013 and December 31, 2012, warrant exercises resulted in the issuances of 1,621,362 and 605,798 shares. At December 31, 2013, the remaining outstanding warrants were exercisable to purchase approximately 1,462,119 shares. The warrants (at date of grant) were valued based upon Black-Scholes option pricing model using expected stock price volatility of 53%; no expected dividends; risk-free interest rate of 2.6%; and an expected life of 8 years, which resulted in a fair value per share of $0.72.

Common Stock Plans

At December 31, 2013, LP had stock-based employee compensation plans as described below. The total compensation expense related to all of LP’s stock-based compensation plans was $8.8 million for the year ended December 31, 2013; $8.4 million for the year ended December 31, 2012 and $7.8 million for the year ended December 31, 2011.

LP recognizes these compensation costs net of an estimated forfeiture rate and recognizes the compensation costs for only those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the vesting term of three years. LP estimated the forfeiture rate for 2013, 2012 and 2011 based on its historical experience during the preceding three years.

80

Stock Compensation Plans

LP grants options to purchase LP common stock and stock settled appreciation rights (SSARs) to key employees and directors. On exercise or issuance, LP generally issues these shares from treasury. The options and SSARs are granted at market price at the date of grant. For employees, options and SSARs become exercisable over three years and expire ten years after the date of grant. For directors, these options become exercisable in 10% increments every three months, starting three months after the date of grant, and expire ten years after the date of grant. At December 31, 2013, 5.6 million shares were available under the current stock award plans for stock-based awards. The following table sets out the weighted average assumptions used to estimate the fair value of the options and SSARs granted using the Black-Scholes option-pricing model:

	2013			2012			2011
Expected stock price volatility	69		%	64		%	64		%
Expected dividend yield	—		%	—		%	—		%
Risk-free interest rate	0.9		%	0.7		%	2.1		%
Expected life of options (in years)	5.0 years			5.1 years			5.2 years
Weighted average fair value of options and SSARs granted	$	11.68		$	4.75		$	5.59

Expected Stock Price Volatility: The fair values of stock-based payments were valued using the Black-Scholes valuation method with a volatility factor based on LP’s historical stock prices.

Expected Dividend Yield: The Black-Scholes valuation model calls for a single expected dividend yield as an input. This is determined based upon current annual dividend as of the date of grant compared to the grant price.

Risk-Free Interest Rate: LP bases the risk-free interest rate used in the Black-Scholes valuation method on U.S. Treasury issues with an equivalent term. Where the expected term of LP’s stock-based awards do not correspond with the terms for which interest rates are quoted, LP performed a straight-line interpolation to determine the rate from the available maturities.

Expected Life of Options: Expected life represents the period that LP’s stock-based awards are expected to be outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior as influenced by changes to the terms of its stock-based awards.

Estimated Pre-vesting Forfeitures: When estimating forfeitures, LP considers voluntary termination behavior as well as workforce reduction programs.

⁽¹⁾  Options or SSARS expected to vest based upon historical forfeiture rate

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between LP’s closing stock price on the last trading day of 2013 and the exercise price, multiplied by the number of in-the-money options and SSARs) that would have been received by the holders had all holders exercised their awards on December 31, 2013. This amount changes based on the market value of LP’s stock as reported by the New York Stock Exchange.

As of December 31, 2013, there was $4.1 million of total unrecognized compensation costs related to stock options and SSARs. These costs are expected to be recognized over a weighted-average period of 1.2 years. LP recognized $3.4 million, $3.7 million and $3.9 million in compensation expense associated with these awards for the years ended December 31, 2013, 2012 and 2011.

Incentive Share Awards

LP has granted incentive share stock awards (restricted stock units) to certain key employees as allowed under the current stock award plans. The awards entitle the participant to receive a specified number of shares of LP common stock at no cost to the participant. Awards granted under this plan vest three years from the date of grant. The market value of these grants approximates the fair value. LP recorded compensation expense related to these awards in 2013, 2012 and 2011 of $2.7 million, $2.3 million and $2.3 million. As of December 31, 2013, there was $3.1 million of total unrecognized compensation cost related to unvested incentive share awards. This expense will be recognized over a weighted-average period of 0.9 years.

Restricted Stock

LP grants restricted stock to certain senior executive employees. The shares vest three years from the date of grant. During the vesting period, the participants have voting rights and receive dividends, but the shares may not be sold, assigned, transferred, pledged or otherwise encumbered. Additionally, granted but unvested shares are forfeited upon termination of employment. The fair value of the restricted shares on the date of the grant is amortized ratably over the vesting period which is generally three years. As of December 31, 2013, there was $2.4 million of total unrecognized compensation costs related to restricted stock. This expense will be recognized over the next year.

Performance Share Awards

In connection with Mr. Stevens' appointment to Chief Executive Officer on May 4, 2012, he was awarded 300,000 performance shares. This award was granted pursuant to the terms of LP's 1997 Incentive Stock Award Plan. If pre-determined market-based performance goals are met, shares of LP's stock will be issued to Mr. Stevens based upon a pre-determined vesting schedule based upon the required service periods. The fair market value of this award was determined based on the fair value as of the date of grant times the number of shares adjusted for the weighted probability of the attainment of certain performance goals. LP recorded compensation expense related to these awards of $0.3 million in 2013. As of December 31, 2013, there was $0.8 million of total unrecognized compensation expense related to this award. This expense will be recognized over the next 2.3 years.

Phantom Stock

During 2011 and 2012, LP made annual grants of phantom stock units to its directors. Subsequent to the approval of the 2013 Omnibus Plan, phantom stock units are no longer granted to directors. The awards are considered liability awards. The director does not receive rights of a shareholder, nor is any stock transfered. The units will be paid in cash at the end of the five year vesting period. The value of one unit is based on the market value of one share of common stock on the vesting date. The cost of the grants is recognized over the vesting period and is included in stock-based compensation expense. As of December 31, 2013, LP had phantom stock units covering 75,816 shares outstanding under this program. LP recorded compensation expense related to these awards of $0.3 million in 2013.

Severance

Over the course of the last three years, LP has entered into several restructuring plans in an effort to sell selected businesses and reduce overall expenses. The detail of the severance accrual and related expense and payments for the last three years is as follows:

Dollar amounts in millions	Year ended December 31,
	2013			2012			2011

For the year ended December 31, 2013, severance expense is primarily related to OSB segment or general and corporate expenses.

17.    LOSS ON SALE OR IMPAIRMENT OF LONG-LIVED ASSETS

The major components of “Loss on sale or impairment of long-lived assets” in the Consolidated Statements of Income for the years ended December 31 are reflected in the table below and are described in the paragraphs following the table:

Dollar amounts in millions	Year ended December 31,
	2013			2012			2011
Impairment charges on long-lived assets	$	(0.1	)	$	(4.4	)	$	(74.0	)

18.    CONTINGENCIES

LP maintains reserves for various contingent liabilities as follows:

	December 31,
Dollar amounts in millions	2013			2012
Environmental reserves	$	14.9		$	14.1
Hardboard siding reserves	0.4			0.7
Total contingencies	15.3			14.8
Current portion	(2.0		)	(2.0		)
Long-term portion	$	13.3		$	12.8

LP’s estimates of its loss contingencies are based on various assumptions and judgments. Due to the numerous uncertainties and variables associated with these assumptions and judgments, both the precision and reliability of the resulting estimates of the related contingencies are subject to substantial uncertainties. LP regularly monitors its estimated exposure to contingencies and, as additional information becomes known, may change its estimates significantly. While no estimate of the range of any such change can be made at this time, the amount that LP may ultimately pay in connection with these matters could materially exceed, in either the near term or the longer term, the amounts accrued to date. LP’s estimates of its loss contingencies do not reflect potential future recoveries from insurance carriers except to the extent that recovery may from time to time be deemed probable as a result of an insurer’s agreement to payment terms.

Environmental Proceedings

LP is involved in a number of environmental proceedings and activities, and may be wholly or partially responsible for known or unknown contamination existing at a number of other sites at which it has conducted operations or disposed of wastes. Based on the information currently available, management believes that any fines, penalties or other costs or losses resulting from these matters will not have a material effect on the financial position, results of operations, cash flows or liquidity of LP.

LP maintains a reserve for undiscounted estimated environmental loss contingencies. This reserve is primarily for estimated future costs of remediation of hazardous or toxic substances at numerous sites currently or previously owned by the Company. LP’s estimates of its environmental loss contingencies are based on various assumptions and judgments, the specific nature of which varies in light of the particular facts and circumstances surrounding each environmental loss contingency. These estimates typically reflect assumptions and judgments as to the probable nature, magnitude and timing of required investigation, remediation and/or monitoring activities and the probable cost of these activities, and in some cases reflect assumptions and judgments as to the obligation or willingness and ability of third parties to bear a proportionate or allocated share of the cost of these activities. Due to the numerous uncertainties and variables associated with these assumptions and judgments, and the effects of changes in governmental regulation and environmental technologies, both the precision and reliability of the resulting estimates of the related contingencies are subject to substantial uncertainties. LP regularly monitors its estimated exposure to environmental loss contingencies and, as additional information becomes known, may change its estimates significantly. However, no estimate of the range of any such change can be made at this time.

In those instances in which LP’s estimated exposure reflects actual or anticipated cost-sharing arrangements with third parties, LP does not believe that it will be exposed to additional material liability as a result of non-performance by such third parties. There are three forms of cost-sharing arrangements under which costs are apportioned to others and are therefore not reflected in LP’s environmental reserves. The amounts involved, the number of sites and a description of each are as follows:

• Approximately $2.1 million of costs, relating to three sites, pursuant to formal cost-sharing arrangements between LP and one or more third parties.

• Approximately $2.7 million of costs, related to two transactions each covering multiple sites, pursuant to agreements contained in purchase and sale documents where LP has sold an asset to a third party and that

88

third party has assumed responsibility for all or a portion of any remediation costs required for the sold asset.

• Approximately $0.4 million of costs, related to one site undergoing cleanup pursuant to federal or state environmental laws, where multiple parties are involved.

LP considers the financial condition of third parties subject to the cost-sharing arrangements discussed above in determining the amounts to be reflected in LP’s environmental reserves. In addition, LP is a party to clean-up activities at two additional sites for which LP does not believe that the failure of a third party to discharge its allocated responsibility would significantly increase LP’s financial responsibility based on the manner in which financial responsibility has been, or is expected to be, allocated.

LP’s estimates of its environmental loss contingencies do not reflect potential future recoveries from insurance carriers except to the extent that recovery may from time to time be deemed probable as a result of a carrier’s agreement to payment terms.

The activity in LP’s reserve for estimated environmental loss contingency reserves for the last three years is summarized in the following table.

	Year ended December 31,
Dollar amounts in millions	2013			2012			2011
Beginning balance	$	14.1		$	15.0		$	14.3
Adjusted to expense (income) during the year	1.3			0.7			1.5
Payments made for claims	(0.5		)	—			—
Payments made for administrative costs	—			(1.6		)	(0.8		)
Ending balance	$	14.9		$	14.1		$	15.0

During 2013, 2012 and 2011, LP adjusted its reserves at a number of sites to reflect current estimates of remediation costs and environmental settlements.

ABT Hardboard Siding Matters

Between 1995 and 1999, ABT Building Products Corporation (“ABT”), ABTco, Inc., a wholly owned subsidiary of ABT (“ABTco” and, together with ABT, the “ABT Entities”), Abitibi-Price Corporation (“Abitibi”), a predecessor of ABT, and certain affiliates of Abitibi (the “Abitibi Affiliates” and, together with Abitibi, the “Abitibi Entities”) were named as defendants in numerous class action and non-class action proceedings brought on behalf of various persons or purported classes of persons (including nationwide classes in the United States and Canada) who own or have purchased or installed hardboard siding manufactured or sold by the defendants. In general, the plaintiffs in these actions have claimed unfair business practices, breach of warranty, fraud, misrepresentation, negligence, and other theories related to alleged defects, deterioration, or other failure of such hardboard siding, and seek unspecified compensatory, punitive, and other damages (including consequential damage to the structures on which the siding was installed), attorneys’ fees and other relief.

LP acquired ABT in February 1999 and ABT was merged into LP in January of 2001. On September 21, 2000, the Circuit Court of Choctaw County, Alabama, under the caption Foster, et al. v. ABTco, Inc., ABT Building Products Corporation, Abitibi-Price, Inc. and Abitibi-Price Corporation (No. CV95-151-M), approved a settlement agreement among the defendants and attorneys representing a nationwide class composed of all persons who own or formerly owned homes or, subject to limited exceptions, other buildings or structures on which hardboard siding manufactured by the defendants was installed between May 15, 1975 and May 15, 2000. Except for approximately 30 persons who timely opted out, the settlement includes and binds all members of the settlement class and resolves all claims asserted in the various proceedings described above. Under the settlement agreement, class members will have twenty-five years after their siding was installed to file a claim.

Under the settlement agreement, the defendants will be entitled to elect to make an offer of settlement to an eligible claimant based on the information set forth in the claim submitted by such claimant, and such claimant will

89

be entitled to accept or reject the offer. If an eligible claimant declines the offer, or if no offer is made, such claimant will be entitled to a payment based on an independent inspection. Such payments will be based on a specified dollar amount (calculated on the basis of statewide averages and ranging from $2.65 to $6.21, depending upon the state) per square foot of covered siding that has experienced specified types of damage, subject to reduction based on the age of the damaged siding and any failure to paint the damaged siding within stated intervals (except in the case of damaged siding installed on mobile homes, as to which a uniform 50% reduction will apply in all circumstances). If applicable, payments under the settlement will also be subject to reduction to reflect any warranty payments or certain other payments previously recovered by a claimant on account of the damaged siding. Under the settlement agreement, LP (as a successor to ABT) will be required to pay the expenses of administering the settlement and certain other costs.

ABT and Abitibi were parties to an agreement of an allocation of liability with respect to claims related to siding sold prior to October 22, 1992. On June 13, 2001, in exchange for a cash payment from Abitibi of approximately $19.0 million which was received in July 2001, LPC, a wholly owned subsidiary of LP, agreed to accept a transfer of all of Abitibi’s rights and obligations under the settlement agreement and the allocation agreement; and LP and LPC agreed to indemnify and hold harmless Abitibi from any cost or liability arising from its sale of hardboard siding in the United States. From the date of the agreement, Abitibi has no further rights, obligations or liabilities under either the class action settlement agreement or the allocation agreement. All such rights, obligations and liabilities have been assigned to and accepted and assumed by LPC.

During 2011, LP increased its reserves in connection with this class action settlement. The additional reserves reflect revised estimates of undiscounted future claim payments and related administrative costs. During 2012 and 2013, LP decreased its reserves in connection with this settlement due to reductions in claims activity. LP believes that the reserve balance at December 31, 2013 will be adequate to cover future payments to claimants and related administrative costs. However, it is possible that additional charges may be required in the future.

The activity in the portion of LP’s loss contingency reserves relating to hardboard siding contingencies for the last three years is summarized in the following table. Included in this table for 2013 and 2012 are reimbursements received by LP from an insurance company for a portion of the claims payments and administrative costs covered under a court judgment related to production and sales of the specific products for specific years.

	Year ended December 31,
Dollar amounts in millions	2013			2012			2011
Beginning balance	$	0.7		$	6.2		$	17.8
Accrued (reversed) to expense	—			(5.0		)	(10.7		)
Claims reimbursement	—			—			0.6
Payments made for claims	(0.2		)	(0.4		)	(1.1		)
Payments made for administrative costs	(0.1		)	(0.1		)	(0.4		)
Ending balance	$	0.4		$	0.7		$	6.2

Other Proceedings

LP and its subsidiaries are parties to other legal proceedings. Based on the information currently available, management believes that the resolution of such proceedings will not have a material adverse effect on the financial position, results of operations, cash flows or liquidity of LP.

90

19.    NON-CONTROLLING INTEREST

In May 2008, LP completed the initial phase of its purchase of a 75% ownership interest in Massisa OSB Industria e Comercio S.A., which operates OSB assets located in Ponta Grossa, Brazil. The purchase was made through LP Brasil Participacoes Ltda., a former limited liability company and indirect subsidiary of LP. The non controlling ownership was subject to a put and call option that became exercisable in 2011, was being accounted for as a redeemable non controlling interest and was accreted over the life of the put and call to the estimated price which was the greater of $18.5 million plus interest plus the greater of $2.0 million or 25% of related working capital or a multiple of earnings before interest and taxes (subject to certain adjustments). The purchase price in 2008 was approximately $56.5 million (including expenses). LP took over operations in November 2008.

In June 2011, LP purchased the remaining 25% ownership of LP Brazil from Massisa for a payment of $24.0 million. Subsequent to the purchase, LP incurred $10.0 million of long term export financing debt in connection with the purchase and used a portion of the proceeds to repay interim borrowing incurred to fund a portion of the purchase price.

20.    COMMITMENTS AND CONTINGENT LIABILITIES

LP is primarily self-insured for workers’ compensation and employee health care liability costs. Self-insurance liabilities for workers’ compensation are determined based upon a valuation performed by an actuarial firm. The estimate of future workers’ compensation liabilities incorporates loss development and an estimate associated with incurred but not yet reported claims. These claims are discounted. Self-insurance liabilities for employee health costs are determined actuarially based upon claims filed and estimated claims incurred but not yet reported. These claims are not discounted.

The Company and its subsidiaries lease certain office, manufacturing, warehousing and other plant sites and equipment. The leases generally provide for the lessee to pay taxes, maintenance, insurance and certain other operating costs of the leased properties.

At December 31, 2013, future minimum annual rent commitments are as follows:

Dollar amounts in millions
Year ended December 31,
2014	$	2.6
2015	2.5
2016	2.1
2017	1.7
2018	1.7
2019 and thereafter	6.1
Total	$	16.7

As of December 31, 2013, LP has entered into non-cancelable subleases for a portion of its corporate headquarters in Nashville, Tennessee. Minimum annual rent commitments have not been reduced by minimum sublease rentals of $0.7 million (in total for all years) due in the future. Rental expense for operating leases amounted to $9.2 million, $8.3 million and $9.5 million in 2013, 2012 and 2011.

21.    GUARANTEES AND INDEMNIFICATIONS

LP is a party to contracts in which LP agrees to indemnify third parties for certain liabilities that arise out of or relate to the subject matter of the contract. In some cases, this indemnity extends to related liabilities arising out of the negligence of the indemnified parties, but usually excludes any liabilities caused by gross negligence or willful misconduct of the indemnified parties. LP cannot estimate the potential amount of future payments under these agreements until events arise that would trigger the liability.

91

Additionally, in connection with certain sales of assets and divestures of businesses, LP has agreed to indemnify the buyer and related parties for certain losses or liabilities incurred by the buyer or such related parties with respect to (1) the representations and warranties made to the buyer by LP in connection with the sales and (2) liabilities related to the pre-closing operations of the assets sold. Indemnities related to pre-closing operations generally include environmental liabilities, tax liabilities and other liabilities not assumed by the buyer.

Indemnities related to the pre-closing operations of sold assets normally do not represent added liabilities for LP, but simply serve to protect the buyer from potential liability associated with the obligations that existed (known and unknown) at the time of the sale. LP records accruals for those pre-closing obligations that are considered probable and estimable. LP is required to record a liability for the fair value of the guarantees that are entered into subsequent to December 31, 2002. LP has not accrued any additional amounts as a result of the indemnity agreements summarized below as LP believes the fair value of the guarantees entered into after December 31, 2002 is not material.

• In connection with various sales of LP’s timberlands, LP has agreed to indemnify various buyers with respect to losses resulting from breaches of limited representations and warranties contained in these agreements. These indemnities generally are capped at a maximum potential liability and have an unspecified duration.

• In connection with the sale of LP’s two inter-related interior hardboard facilities to Decorative Panels International Inc. in 2004, LP provided a 10-year indemnity for unknown environmental claims, capped at $4.0 million with a $0.3 million deductible. This indemnity will expire in May 2014.

• In connection with the sale by LP Canada Pulp Ltd (LPCP) of its pulp mill in Chetwynd, BC, Canada to Tembec, Ltd in October 2002, LP provided an indemnity of unspecified duration provided by LPCP for liabilities arising out of pre-closing operations. These indemnities, which do not extend to environmental liabilities, are capped at C$15.0 million in the aggregate.

LP also has various other indemnities that are individually and in the aggregate immaterial.

LP will record a liability related to specific indemnification when future payment is probable and the amount is estimable.

Additionally, LP offers warranties on the sale of most of its products and records an accrual for estimated future claims. Such accruals are based upon historical experience and management’s estimate of the level of future claims. The activity in warranty reserves for the last three years is summarized in the following table.

	Year ended December 31,
Dollar amounts in millions	2013			2012			2011
Beginning balance	$	21.4		$	30.3		$	29.5
Accrued to expense during the year	2.7			4.5			13.7
Credited to other operating credits and charges	17.7			(1.8		)	—
Payments made	(12.5		)	(11.6		)	(12.9		)
Total warranty reserves	29.3			21.4			30.3
Current portion	(12.0		)	(12.0		)	(12.0		)
Long term portion	$	17.3		$	9.4		$	18.3

The current portion of the warranty reserve is included in “Accounts payable and accrued liabilities” and the long-term portion is included in “Other long-term liabilities” on the Consolidated Balance Sheets.

During 2013, LP increased the warranty reserve associated with CanExel products sold in certain geographic areas by $17.7 million. The changes to the reserve reflected revised estimates of future claims.

During 2012, LP increased the warranty reserve related to its discontinued vinyl siding products by $3.6 million. The change to the reserve reflected revised estimates of future claims.

92

LP increased the warranty reserves related to discontinued composite decking products by $2 million in 2013 and $12 million in 2011. The additional reserves reflect revised estimates of future claim payments based upon an increase in decking warranty claims related to a specific operation and specific time period. During the fourth quarter of 2008, LP established a voluntary recall of the affected decking. During the second quarter of 2009, LP established a formal recall program under the Consumer Products Safety Board requirements for these products. No additional reserve increase was required in connection with the establishment of the formal program. LP continues to monitor warranty and other claims associated with these products and with the recall program (see Note 18) and believe as of December 31, 2013 that the reserves associated with these matters are adequate.

LP believes that the warranty reserve balances at December 31, 2013 are adequate to cover future warranty payments. However, it is possible that additional charges may be required.

22.    DISCONTINUED OPERATIONS

Over the last several years, LP has adopted and implemented plans to sell selected businesses and assets in order to improve its operating results. For all periods presented, these operations include residual losses of mills divested in past years and associated warranty and other liabilities associated with these operations.

Dollar amounts in millions	2013			2012			2011
Sales	$	16.0		$	25.0		$	28.3
Operating profit	(0.4		)	(1.1		)	(8.6		)

During 2013, LP sold its moulding operations and recognized a gain of $1.7 million on the sale. Included in the operating losses of discontinued operations for the year ended December 31, 2013 is an increase in warranty reserve of $2.0 million associated with discontinued composite decking products.

Included in the operating losses of discontinued operations for the year ended December 31, 2012 is an increase in warranty reserves of $3.6 million associated with products previously discontinued based upon significant increases in warranty claim activity during the year ended December 31, 2012.

Included in the operating losses of discontinued operations for the year ended December 31, 2011 is an increase in warranty reserves of $12.0 million associated with products previously discontinued based upon significant increases in recent warranty claim activity.

23.    ACCUMULATED COMPREHENSIVE LOSS

Accumulated comprehensive loss consists of cumulative translation adjustments, unrealized gains (losses) on certain derivative instruments and pension and post retirement adjustments. Other comprehensive income activity, net of tax, is provided in the following table for the years ended December 31, 2013, 2012 and 2011.

Foreign currency translation adjustments exclude income tax expense (benefit) given that these adjustments arise out of the translation of assets into the reporting currency that is separate from the taxable income and is deemed to be reinvested for an indefinite period of time. The pension adjustments included income tax benefits of $15.5 million, $0.9 million and $14.1 million in 2013, 2012 and 2011.

24.    ACQUISITION OF PEACE VALLEY OSB

On May 31, 2013, LP acquired full control of the Peace Valley OSB joint venture in which LP previously maintained a 50% interest. Peace Valley OSB's results of operations have been fully consolidated in all periods subsequent to May 31, 2013. Since LP previously served as the exclusive distributor of all OSB produced by this venture, this acquisition will not have a material impact on LP's consolidated net sales.

Due to LP's pre-existing 50% ownership interest in Peace Valley OSB, this acquisition was accounted for as a step acquisition in accordance with ASC 805, Business Combinations (“ASC 805”). Accordingly, LP recognized a gain of $35.9 million in connection with this transaction to remeasure its 50% ownership interest in Peace Valley at fair value on the acquisition date. The gain is reflected in Other operating credits and charges, net on the Consolidated Statement of Income. The fair value of LP's existing 50% interest ($95.9 million) was determined using a combination of the income and market approach. In completing this valuation, management considered future earnings and cash flow potential of the business, earnings multiples, and recent market transactions of similar businesses. This gain is included in "Non-operating income (expense)."

The purchase price of the 50% acquired interest was $74.6 million (including working capital) paid in cash. Additionally, as part of the purchase consideration, LP agreed to pay contingent consideration equal to a pre-defined percentage of the operation's earnings before interest, taxes, depreciation and amortization (EBITDA) over a pre-defined threshold for each of the next three years. As of May 31, 2013, the fair value of the contingent consideration payable was valued at $24.3 million and was recorded in “accounts payable and accrued liabilities” and “other long term liabilities”. The fair value of the contingent consideration payable will be remeasured at the end of each reporting period. During the remainder of 2013, the fair value of the contingent consideration payable was remeasured and reduced by $20.5 million due to the decline in projected OSB prices in the near term as compared to the date of acquisition. This reduction in OSB results in a reduction in the estimated EBITDA of the operation.

Including the 50% interest previously owned by LP, LP acquired net assets of $194.8 million, consisting of $22.7 million in current assets, $146.4 million in fixed asset, $43.8 million of intangible assets (comprised of $34.1 million of timber licenses and $9.7 million of goodwill) and $8.7 million in current liabilities and $9.4 million in long term liabilities. Additional financial information about Peace Valley OSB (e.g., pro forma financial information and allocation of purchase price) is not presented because such information is not material to LP's results of operations and financial position.

25.    PROPOSED ACQUISITION OF AINSWORTH LUMBER CO. LTD.

In September of 2013 LP entered into an Arrangement Agreement (the “Arrangement”) with Ainsworth Lumber Co. Ltd., a British Columbia corporation (“Ainsworth”), providing an arrangement under British Columbia law whereby a wholly owned subsidiary of the Company will acquire all of the outstanding shares of Ainsworth capital stock in exchange for 0.114 shares of LP common stock (“LP Shares”) and C$1.94 in cash per Ainsworth common share (“Ainsworth Shares”) subject to certain terms and conditions. Although the Arrangement provides for Ainsworth shareholders to elect among cash consideration, share consideration and mixed consideration, proration provisions will ensure that the aggregate amounts of cash and LP Shares issued in the Transaction are fixed at approximately C$467.0 million and 27.5 million LP Shares, respectively.

The requisite approvals of the Transaction by Ainsworth shareholders and the Supreme Court of British Columbia were obtained on October 29, 2013 and October 31, 2013, respectively. As of the date of this report, the consummation of the Transaction remained subject to other closing conditions, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the receipt of other regulatory approvals and clearances, including under the Canadian Competition Act and the Investment Act

95

of Canada. LP and Ainsworth have agreed to endeavor to cause all closing conditions (including the receipt of regulatory approvals) to be satisfied, which under certain circumstances could require the taking of actions that could adversely affect the value of the Transaction to us.

On February 13, 2014, Ainsworth and LP announced that they have entered into timing agreements with each of the Canadian Competition Bureau (the “CCB”) and the Antitrust Division of the U.S. Department of Justice (the “DOJ”) pursuant to which Ainsworth and LP have agreed, subject to certain conditions, that they will not consummate LP’s acquisition of Ainsworth before March 13, 2014 as the CCB and the DOJ continue their reviews.

As a consequence of the timing agreements described above, Ainsworth and LP also announced that they have agreed to extend the outside date for completion of the Arrangement from March 4, 2014 to April 18, 2014. The Arrangement permits either party to further extend the outside date for two additional 45 day periods if required to obtain certain regulatory approvals.

The closing of the Arrangement remains subject to a number of conditions, including the expiration or termination of the waiting period under the HSR Act and the receipt of other regulatory approvals and clearances including under the Canadian Competition Act. Subject to obtaining required regulatory approvals and clearances and the satisfaction or waiver of other closing conditions, it is now anticipated that the Arrangement will be completed before the end of the second quarter of 2014.

The Arrangement contains certain termination rights for each of LP and Ainsworth. Either party may terminate the Arrangement Agreement if: (i) the parties mutually agree; (ii) the Transaction has not been consummated by March 31, 2014 (subject to extension in certain circumstances); (iii) a governmental authority issues a law or order prohibiting the Transaction; (iv) the other party materially breaches its representations, warranties or covenants such that the applicable closing condition would not to be satisfied; or (v) the other party has incurred a Material Adverse Effect (as defined in the Arrangement Agreement).

LP expects to fund the purchase price payable in the Transaction and related fees and expenses through a combination of cash on hand at LP and Ainsworth and borrowings under our revolving credit facility. The obligations of the lenders to provide debt financing under the debt commitments are subject to customary conditions.

On October 17, 2013, Ainsworth issued a press release announcing that it had received the requisite consents in connection with its consent solicitation (the "Consent Solicitation") from holders of Ainsworth's 7.5% Senior Secured Notes due 2017 (the "Notes") . The press release also announced that Ainsworth has entered into a supplemental indenture relating to the Notes, which modified certain definitions in the indenture relating to the Notes (the "Indenture") so that the consummation of the Transaction pursuant to the Arrangement Agreement, and the designation by LP of members of Ainsworth’s board of directors upon and after the consummation of the Transaction, will not constitute a “Change of Control” under the Indenture and Ainsworth will not be required to make a “Change of Control Offer” under the Indenture in connection with the Transaction. Subject to the satisfaction or waiver of the conditions set forth in the solicitation statement distributed by Ainsworth to holders of the Notes, LP will make the consent payments contemplated thereby as and when they become due. Promptly following the consummation of the Transaction, LP will unconditionally guarantee the prompt payment and performance of the obligations of Ainsworth under the Indenture and the Notes.

The Transaction is expected to have a material effect on LP’s consolidated financial position, results of operations and cash flows. For additional information, see the Ainsworth Lumber Co. Ltd. Notice of Special Meeting and Management Proxy Circular furnished as Exhibit 99.1 to LP's Current Report on Form 8-K dated September 30, 2013.

Changes in Internal Control over Financial Reporting

There were no changes in LP’s internal control over financial reporting that occurred during LP’s most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in the Exchange Act Rule 13a-15(f). The Company’s management conducted an assessment of the Company’s internal control over financial reporting based on the framework established by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (1992). Based on this assessment, the Company’s management has concluded that, as of December 31, 2013, the Company’s internal control over financial reporting is effective. The Company’s independent registered public accounting firm, Deloitte & Touche LLP, has audited the Company’s consolidated financial statements and has issued an attestation report the Company’s internal control over financial reporting, as stated in their report included herein.

The certifications of LP’s Chief Executive Officer and Chief Financial Officer required under Section 302 of the Sarbanes-Oxley Act have been filed as Exhibits 31.1 and 31.2 to this report. Additionally, in 2013 LP’s Chief Executive Officer certified to the New York Stock Exchange (“NYSE”) that he was not aware of any violation by LP of the NYSE corporate governance listing standards.

LP completed the acquisition of the remaining 50% interest of the Peace Valley OSB joint venture in May of 2013. Due to the timing of the acquisition, we have excluded these operations from our evaluation of the effectiveness of internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Louisiana-Pacific Corporation

We have audited the internal control over financial reporting of Louisiana-Pacific Corporation and subsidiaries (the "Company") as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. As described in Management’s Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting of Peace Valley OSB. The Company completed the acquisition of the remaining 50% interest of the Peace Valley OSB joint venture in May of 2013. Accordingly, our audit did not include the internal control over financial reporting of Peace Valley OSB. 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 over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

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

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the 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, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2013 of the Company and our report dated February 27, 2014 expressed an unqualified opinion on those financial statements.

STOCK APPRECIATION RIGHTS AWARD AGREEMENT

Corporation: Louisiana-Pacific Corporation, a Delaware corporation (“Corporation”)

Plan: Louisiana-Pacific Corporation 2013 Omnibus Stock Award Plan (the “Plan”)

Award: [XXX] freestanding stock-settled stock appreciation rights (“SARs”)

Grant Date: __________ ___, 20___ (“Grant Date”)

Corporation and Participant agree as follows:

1.Defined Terms. Capitalized terms not otherwise defined in this Stock Appreciation Rights Award Agreement (the “Agreement”) have the meanings given them in the Plan. In addition, for purposes of this Agreement, “Base Price” means $__________, which was the Fair Market Value of the Common Stock on the Grant Date.

2.Grant of SARs. As of the Grant Date, Corporation has granted to Participant the SARs. The SARs represent the right of Participant to receive Shares in an amount equal to 100% of the Spread on the date on which the SARs are exercised subject to and upon the terms and conditions of this Agreement and the Plan. For purposes of this Agreement, “Spread” means the excess of the Fair Market Value of a Share on the date when a SAR is exercised over the Base Price.

3.Acknowledgment. Participant acknowledges that the SARs are subject to the terms and conditions set forth in this Agreement and in the Plan.

4.Vesting of SARs.

(a)The SARs covered by this Agreement shall become exercisable as described in this Section. One-third of the SARs shall become exercisable on the first anniversary of the Grant Date if Participant remains in the continuous employ of Corporation or one of its Subsidiaries from

the Grant Date through such first anniversary. An additional one-third of the SARs shall become exercisable on each subsequent anniversary of the Grant Date, through the third anniversary of the Grant Date, when 100% of the SARs shall have become exercisable, if Participant remains in the continuous employ of Corporation or one of its Subsidiaries from the Grant Date through each such anniversary. For purposes of this Agreement, “continuous employ” means the absence of any interruption or termination of Participant’s employment with Corporation or with a Subsidiary. Continuous employment shall not be considered interrupted or terminated in the case of sick leave, military leave or any other leave of absence approved by Corporation or in the case of transfers between locations of Corporation and its Subsidiaries.

(b)Notwithstanding Section 4(a) above, the SARs granted hereby shall become immediately exercisable in full if at any time during the continuous employment of Participant with Corporation or a Subsidiary, and prior to the termination of the SARs, any of the following events occur:

(i) Participant’s death or Disability while Participant is continuously employed by Corporation or any of its Subsidiaries; or

(ii) a Change of Control.

5.Exercise of SARs.

(a)To the extent exercisable as provided in Section 4 of this Agreement, the SARs may be exercised in whole or in part by delivery to Corporation of a notice in form and substance satisfactory to Corporation specifying the number of SARs to be exercised and the date of exercise.

(b)Upon exercise, Corporation will issue to Participant, with respect to the number of SARs that are exercised, the number of Shares that equal the Fair Market Value per Share on the date of exercise divided into the Spread, rounded down to the nearest whole Share.

6.Termination of SARs. Both exercisable and nonexercisable SARs shall terminate, as provided below, upon the earliest to occur of the following:

(a)five days after Participant ceases to be an employee of Corporation or a Subsidiary due to involuntary termination by Corporation or a Subsidiary for cause;

(b)30 days after Participant ceases to be an employee of Corporation or a Subsidiary, unless Participant ceases to be such employee in a manner described in clause (a), (c), (d) or (e) of this Section;

(c)One year after Participant’s Disability, if Participant’s Disability occurs while continuously employed by Corporation or a Subsidiary;

(d)One year after the death of Participant, if Participant dies while continuously employed by Corporation or a Subsidiary or within the period specified in clause (b) above or clause (e) below if applicable to Participant;

(e)Ten years from the Grant Date if Participant terminates employment for any reason other than involuntary termination by Corporation or a Subsidiary for cause and has attained age 55 and completed five years of service upon the termination date,; and

(f)Ten years from the Grant Date.

7.Compliance with Law. The SARs shall not be exercisable if such exercise would involve a violation of any applicable federal or state securities law, and Corporation hereby agrees to make reasonable efforts to comply with any applicable federal and state securities laws.

8.Adjustments. The SARs shall be subject to adjustment in accordance with Article 12 of the Plan.

9.Withholding. To the extent that Corporation is required to withhold federal, state, local or foreign taxes in connection with the exercise of the SARs, and the amounts available to Corporation for such withholding are insufficient, it shall be a condition to such exercise that

Participant make arrangements satisfactory to Corporation for payment of the balance of such taxes required to be withheld. Participant may elect that all or any part of such withholding requirement be satisfied by retention by Corporation of a portion of the Shares to be delivered to Participant or by delivering to Corporation other Shares held by Participant. If such election is made, the Shares so retained or delivered shall be credited against such withholding requirement at the Fair Market Value per Share on the date of such exercise. In no event shall the market value of the Shares to be withheld and/or delivered pursuant to this Section 9 to satisfy applicable withholding taxes exceed the minimum amount of taxes required to be withheld.

10.No Employment Rights. The grant of the SARs under this Agreement to Participant is a voluntary, discretionary award being made on a one-time basis and it does not constitute a commitment to make any future awards. The grant of the SARs and any payments made hereunder will not be considered salary or other compensation for purposes of any severance pay or similar allowance, except as otherwise required by law. Nothing in this Agreement will give Participant any right to continue employment with Corporation or any Subsidiary, as the case may be, or interfere in any way with the right of Corporation or a Subsidiary to terminate the employment of Participant at any time.

11.Relation to Other Benefits. Any economic or other benefit to Participant under this Agreement or the Plan shall not be taken into account in determining any benefits to which Participant may be entitled under any profit sharing, retirement or other benefit or compensation plan maintained by Corporation or a Subsidiary and shall not affect the amount of any life insurance coverage available to any beneficiary under any life insurance plan covering employees of Corporation or a Subsidiary.

12.Amendments. Subject to Article 13 of the Plan, any amendment to the Plan shall be deemed to be an amendment to this Agreement to the extent that the amendment is applicable hereto;

provided, however, that (a) no amendment shall adversely affect the rights of Participant under this Agreement without Participant’s written consent, and (b) Participant’s consent shall not be required to an amendment that is deemed necessary by Corporation to ensure compliance with Section 409A of the Code.

13.Severability. In the event that one or more of the provisions of this Agreement shall be invalidated for any reason by a court of competent jurisdiction, any provision so invalidated shall be deemed to be separable from the other provisions hereof, and the remaining provisions hereof shall continue to be valid and fully enforceable.

14.Relation to Plan. This Agreement is subject to the terms and conditions of the Plan. In the event of any inconsistency between the provisions of this Agreement and the Plan, the Plan shall govern. The Administrator acting pursuant to the Plan, as constituted from time to time, shall, except as expressly provided otherwise herein or in the Plan, have the right to determine any questions which arise in connection with this Agreement.

15.Successors and Assigns. Without limiting the provisions of this Agreement, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the successors, administrators, heirs, legal representatives and assigns of Participant, and the successors and assigns of Corporation.

16.Compliance With Section 409A of the Code. To the extent applicable, it is intended that this Agreement and the Plan comply with the provisions of Section 409A of the Code. This Agreement and the Plan shall be administered in a manner consistent with this intent, and any provision that would cause this Agreement or the Plan to fail to satisfy Section 409A of the Code shall have no force or effect until amended to comply with Section 409A of the Code (which amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by Corporation without the consent of Participant).

Plan: Louisiana-Pacific Corporation 2013 Omnibus Stock Award Plan (the “Plan”)

Award: [XXX] shares of Corporation’s Common Stock (“Restricted Stock”)

Grant Date: __________ ___, 20___ (“Grant Date”)

Corporation and Participant agree as follows:

(a)The _____ anniversary of the Grant Date; or

(b)The end of Participant’s continuous employment with the Company or a Subsidiary by reason of:

(i)death;

(ii) Disability; or

(iii)a Change of Control.

For purposes of this Agreement, “continuously employed” means the absence of any interruption or termination of Participant’s employment with Corporation or with a Subsidiary. Continuous employment shall not be considered interrupted or terminated in the case of sick leave, military leave or any other leave of absence approved by Corporation or in the case of transfers between locations of Corporation and its Subsidiaries.

5. Restrictions during Restriction Period. Subject to Section 6.6(a) of the Plan, during the Restriction Period:

(a)Participant may not sell, assign, pledge, transfer, encumber or otherwise dispose of the Restricted Stock; and

(b)In the event Participant ceases to be continuously employed by the Company or a Subsidiary prior to the expiration of the Restriction Period for any reaon other than death, Disability, or in connection with a Change of Control, Participant will immediately and automatically forfeit all shares of Restricted Stock subject to the Award, the Restricted Stock will automatically revert to Corporation, and Participant will cease to have any rights with respect to such Restricted Stock.

6.Rights during Restriction Period. During the Restriction Period for the Restricted Stock, Participant will have all the rights of a stockholder with respect to the Restricted Stock, including without limitation the right to exercise all voting rights with respect to the Restricted Stock and the right to receive cash dividends with respect to the Restricted Stock.

7. Vesting of Awards. Upon the Vesting of any Restricted Stock (due to expiration of the Restriction Period for that Award), the Shares previously subject to such Award will no longer be subject to the Restrictions.

8. Tax Withholding. Corporation will have the right to deduct from the Restricted Stock any federal, state, or local taxes of any kind required by law to be withheld with respect to such Restricted Stock or to take such other action as may be necessary in the opinion of Corporation to satisfy all obligations for the payment of such taxes. Participant must make arrangements satisfactory to Corporation for the satisfaction of any such withholding tax obligations. Corporation will not be required to make any such payment until such obligations are satisfied. Participant may elect that all or any part of such withholding requirement be satisfied by retention by Corporation of a portion of the Shares that may Vest or by delivering to Corporation other Shares held by Participant. If such election is made, the Shares so retained or delivered shall be credited against such withholding requirement at the Fair Market Value per Share of such Shares on the date of such delivery. In no event will the fair market value of the Shares to be withheld and/or delivered pursuant to this Section 8 to satisfy applicable withholding taxes exceed the minimum amount of taxes required to be withheld.

9.Miscellaneous.

(a)Compliance With Law. Corporation shall make reasonable efforts to comply with all applicable federal and state securities laws.

(b)Compliance With Section 409A of the Code. To the extent applicable, it is intended that this Agreement and the Plan comply with the provisions of Section 409A of the Code. This Agreement and the Plan shall be administered in a manner consistent with this intent, and any provision that would cause this Agreement or the Plan to fail to satisfy Section 409A of the Code shall have no force or effect until amended to comply with Section 409A of the Code (which

amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by Corporation without the consent of Participant).

(c)Interpretation. Any reference in this Agreement to Section 409A of the Code will also include any proposed, temporary or final regulations, or any other guidance, promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service. Except as expressly provided in this Agreement, capitalized terms used herein will have the meaning ascribed to such terms in the Plan.

(d)No Employment Rights. The grant of the Restricted Stock under this Agreement to Participant is a voluntary, discretionary award being made on a one-time basis and it does not constitute a commitment to make any future awards. The grant of the Restricted Stock and any payments made hereunder will not be considered salary or other compensation for purposes of any severance pay or similar allowance, except as otherwise required by law. Nothing contained in this Agreement shall confer upon Participant any right to be employed or remain employed by Corporation or any of its Subsidiaries, nor limit or affect in any manner the right of Corporation or any of its Subsidiaries to terminate the employment or adjust the compensation of Participant.

(e)Relation to Other Benefits. Any economic or other benefit to Participant under this Agreement or the Plan shall not be taken into account in determining any benefits to which Participant may be entitled under any profit-sharing, retirement or other benefit or compensation plan maintained by Corporation or any of its Subsidiaries and shall not affect the amount of any life insurance coverage available to any beneficiary under any life insurance plan covering employees of Corporation or any of its Subsidiaries.

(f)Amendments. Any amendment to the Plan shall be deemed to be an amendment to this Agreement to the extent that the amendment is applicable hereto; provided, however, that (i) no amendment shall adversely affect the rights of Participant under this Agreement

without Participant’s written consent, and (ii) Participant’s consent shall not be required to an amendment that is deemed necessary by Corporation to ensure compliance with Section 409A of the Code.

(g)Severability. In the event that one or more of the provisions of this Agreement shall be invalidated for any reason by a court of competent jurisdiction, any provision so invalidated shall be deemed to be separable from the other provisions hereof, and the remaining provisions hereof shall continue to be valid and fully enforceable.

(h)Relation to Plan. This Agreement is subject to the terms and conditions of the Plan. In the event of any inconsistency between the provisions of this Agreement and the Plan, the Plan shall govern. The Administrator acting pursuant to the Plan, as constituted from time to time, shall, except as expressly provided otherwise herein or in the Plan, have the right to determine any questions which arise in connection with this Agreement.

1.Defined Terms. Capitalized terms not otherwise defined in this Restricted Stock Unit Award Agreement (the “Agreement”) have the meanings given them in the Plan.

2.Grant of Restricted Stock Units. As of the Grant Date, Corporation has granted to Participant the Restricted Stock Units (which Award is a form of restricted stock grant under the Plan).

3.Acknowledgment. Participant acknowledges that the Restricted Stock Units are subject to the terms and conditions set forth in this Agreement and in the Plan.

4. Vesting of Restricted Stock Units.

(a)The Restricted Stock Units will become nonforfeitable and payable to Participant pursuant to Section 5 hereof on the _____ anniversary of the Grant Date (the “Vesting Date”), conditioned upon Participant’s continuous employment with the Company or a Subsidiary through the Vesting Date. Any Restricted Stock Units that do not so become nonforfeitable will be forfeited, including, except as provided in Section 4(b) below, if Participant ceases to be

continuously employed by Corporation or a Subsidiary prior to the Vesting Date. For purposes of this Agreement, “continuously employed” means the absence of any interruption or termination of Participant’s employment with Corporation or with a Subsidiary. Continuous employment shall not be considered interrupted or terminated in the case of sick leave, military leave or any other leave of absence approved by Corporation or in the case of transfers between locations of Corporation and its Subsidiaries.

(b)Notwithstanding Section 4(a) above, all of the Restricted Stock Units will become nonforfeitable and payable to Participant pursuant to Section 5 hereof upon the occurrence of any of the following events (each, an “Early Vesting Event”) if the Restricted Stock Units have not previously been forfeited or become nonforfeitable: termination of Participant’s continuous employment by reason of Participant’s death, Disability, or a Change of Control.

5. Form and Time of Payment of Restricted Stock Units.

(a)Payment for the Restricted Stock Units, after and to the extent they have become nonforfeitable, shall be made in the form of Shares. Except as provided in Section 5(b), such payment shall be made within 10 days following the date that the Restricted Stock Units become nonforfeitable pursuant to Section 4 hereof.

(b)If the Restricted Stock Units become nonforfeitable (i) by reason of the occurrence of a Change of Control as described in Section 4(b), and if the Change of Control does not constitute a “change in control” for purposes of Section 409A(a)(2)(A)(v) of the Code, or (ii) by reason of a termination of Participant’s employment by reason of Participant’s Disability, and if such termination does not constitute a “separation from service” for purposes of Section 409A(a)(2)(A)(i) of the Code, then payment for the Restricted Stock Units will be made upon the earliest of (w) Participant’s “separation from service” with Corporation and its Subsidiaries (determined in accordance with Section 409A(a)(2)(A)(i) of the Code), (x) the Vesting Date, (y) Participant’s death,

or (z) the occurrence of a Change in Control that constitutes a “change in control” for purposes of Section 409A(a)(2)(A)(v) of the Code.

(c)If the Restricted Stock Units become payable on Participant’s “separation from service” with the Corporation and its Subsidiary within the meaning of Section 409A(a)(2)(A)(i) of Code and Participant is a “specified employee” as determined pursuant to procedures adopted by Corporation in compliance with Section 409A of the Code, then payment for the Restricted Stock Units shall be made on the earlier of the first day of the seventh month after the date of Participant’s “separation from service” with Corporation and its Subsidiaries within the meaning of Section 409A(a)(2)(A)(i) of the Code or the Participant’s death.

(d)Except to the extent provided by Section 409A of the Code and permitted by the Administrator, no Shares may be issued to Participant at a time earlier than otherwise expressly provided in this Agreement.

(e)Corporation’s obligations to Participant with respect to the Restricted Stock Units will be satisfied in full upon the issuance of Shares corresponding to such Restricted Stock Units.

6. Restrictions during Vesting Period. Subject to Section 6.6(a) of the Plan, prior to the Vesting Date or an Early Vesting Date, Participant may not sell, assign, pledge, transfer, encumber or otherwise dispose of the Restricted Stock Units (or the Shares subject to the Restricted Stock Units).

7.Dividend, Voting and Other Rights. Participant will have no rights of ownership in the Shares underlying the Restricted Stock Units, no right to dividends and no right to vote the Shares underlying the Restricted Stock Units until the date on which the Shares underlying the Restricted Stock Units are issued or transferred to Participant pursuant to Section 5 above. However, from and after the Grant Date and until the earlier of (a) the time when the Restricted Stock Units are settled in Shares in accordance with Section 5 hereof or (b) the time when

Participant’s right to receive Shares in payment of the Restricted Stock Units is forfeited in accordance with Section 4, on the date that Corporation pays a cash dividend (if any) to holders of Shares generally, Corporation shall accrue an amount of cash equal to the product of the per-Share amount of the dividend paid multiplied by the number of such Restricted Stock Units. Such amount shall be paid to Participant only if, and at the same time as, the underlying Shares are delivered to Participant pursuant to Section 5.

8. Tax Withholding. Corporation will have the right to deduct from any settlement of the Restricted Stock Units any federal, state, or local taxes of any kind required by law to be withheld with respect to such payments or to take such other action as may be necessary in the opinion of Corporation to satisfy all obligations for the payment of such taxes. Participant must make arrangements satisfactory to Corporation for the satisfaction of any such withholding tax obligations. Corporation will not be required to make any such payment until such obligations are satisfied. Participant may elect that all or any part of such withholding requirement be satisfied by retention by Corporation of a portion of the Shares to be delivered to Participant or by delivering to Corporation other Shares held by Participant. If such election is made, the Shares so retained or delivered shall be credited against such withholding requirement at the Fair Market Value per Share of such Shares on the date of such delivery. In no event will the fair market value of the Shares to be withheld and/or delivered pursuant to this Section 8 to satisfy applicable withholding taxes exceed the minimum amount of taxes required to be withheld.

9.Miscellaneous.

(a)Compliance With Law. Corporation shall make reasonable efforts to comply with all applicable federal and state securities laws; provided, however, notwithstanding any other provision of the Plan and this Agreement, Corporation shall not be obligated to issue any Shares pursuant to this Agreement if the issuance thereof would result in a violation of any such law.

This Agreement and the Plan shall be administered in a manner consistent with this intent, and any provision that would cause this Agreement or the Plan to fail to satisfy Section 409A of the Code shall have no force or effect until amended to comply with Section 409A of the Code (which amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by Corporation without the consent of Participant).

(c)Interpretation. Any reference in this Agreement to Section 409A of the Code will also include any proposed, temporary or final regulations, or any other guidance, promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.

compensation plan maintained by Corporation or any of its Subsidiaries and shall not affect the amount of any life insurance coverage available to any beneficiary under any life insurance plan covering employees of Corporation or any of its Subsidiaries

Segment Reporting [Abstract]

Segment Information

SEGMENT INFORMATION

LP operates in four segments: North America Oriented Strand Board (OSB); Siding; Engineered Wood Products (EWP) and South America. LP’s business units have been aggregated into these four segments based upon the similarity of economic characteristics, customers and distribution methods. LP’s results of operations are summarized below for each of these segments separately as well as for the “other” category which comprises other products that are not individually significant. Segment information was prepared in accordance with the same accounting principles as those described in Note 1. LP evaluates the performance of its business segments based upon operating profits excluding other operating credits and charges, net, gain (loss) on sales of and impairments of long-lived assets, general corporate and other expenses, translation gains and losses, interest and income taxes.

The OSB segment includes OSB products produced in North America. The siding segment includes Smart Side^® siding products; Canexel siding products; and other related products. The engineered wood products segment includes laminated veneer lumber and laminated strand lumber; I-joists; plywood; and other related products. The South America segment includes products produced and or sold (generally OSB) in South America.

Commitments and Contingencies Disclosure [Abstract]

Contingencies Disclosure [Text Block]

CONTINGENCIES

LP maintains reserves for various contingent liabilities as follows:

	December 31,
Dollar amounts in millions	2013			2012
Environmental reserves	$	14.9		$	14.1
Hardboard siding reserves	0.4			0.7
Total contingencies	15.3			14.8
Current portion	(2.0		)	(2.0		)
Long-term portion	$	13.3		$	12.8

LP’s estimates of its loss contingencies are based on various assumptions and judgments. Due to the numerous uncertainties and variables associated with these assumptions and judgments, both the precision and reliability of the resulting estimates of the related contingencies are subject to substantial uncertainties. LP regularly monitors its estimated exposure to contingencies and, as additional information becomes known, may change its estimates significantly. While no estimate of the range of any such change can be made at this time, the amount that LP may ultimately pay in connection with these matters could materially exceed, in either the near term or the longer term, the amounts accrued to date. LP’s estimates of its loss contingencies do not reflect potential future recoveries from insurance carriers except to the extent that recovery may from time to time be deemed probable as a result of an insurer’s agreement to payment terms.

Environmental Proceedings

LP is involved in a number of environmental proceedings and activities, and may be wholly or partially responsible for known or unknown contamination existing at a number of other sites at which it has conducted operations or disposed of wastes. Based on the information currently available, management believes that any fines, penalties or other costs or losses resulting from these matters will not have a material effect on the financial position, results of operations, cash flows or liquidity of LP.

LP maintains a reserve for undiscounted estimated environmental loss contingencies. This reserve is primarily for estimated future costs of remediation of hazardous or toxic substances at numerous sites currently or previously owned by the Company. LP’s estimates of its environmental loss contingencies are based on various assumptions and judgments, the specific nature of which varies in light of the particular facts and circumstances surrounding each environmental loss contingency. These estimates typically reflect assumptions and judgments as to the probable nature, magnitude and timing of required investigation, remediation and/or monitoring activities and the probable cost of these activities, and in some cases reflect assumptions and judgments as to the obligation or willingness and ability of third parties to bear a proportionate or allocated share of the cost of these activities. Due to the numerous uncertainties and variables associated with these assumptions and judgments, and the effects of changes in governmental regulation and environmental technologies, both the precision and reliability of the resulting estimates of the related contingencies are subject to substantial uncertainties. LP regularly monitors its estimated exposure to environmental loss contingencies and, as additional information becomes known, may change its estimates significantly. However, no estimate of the range of any such change can be made at this time.

In those instances in which LP’s estimated exposure reflects actual or anticipated cost-sharing arrangements with third parties, LP does not believe that it will be exposed to additional material liability as a result of non-performance by such third parties. There are three forms of cost-sharing arrangements under which costs are apportioned to others and are therefore not reflected in LP’s environmental reserves. The amounts involved, the number of sites and a description of each are as follows:

• Approximately $2.1 million of costs, relating to three sites, pursuant to formal cost-sharing arrangements between LP and one or more third parties.

• Approximately $2.7 million of costs, related to two transactions each covering multiple sites, pursuant to agreements contained in purchase and sale documents where LP has sold an asset to a third party and that third party has assumed responsibility for all or a portion of any remediation costs required for the sold asset.

• Approximately $0.4 million of costs, related to one site undergoing cleanup pursuant to federal or state environmental laws, where multiple parties are involved.

LP considers the financial condition of third parties subject to the cost-sharing arrangements discussed above in determining the amounts to be reflected in LP’s environmental reserves. In addition, LP is a party to clean-up activities at two additional sites for which LP does not believe that the failure of a third party to discharge its allocated responsibility would significantly increase LP’s financial responsibility based on the manner in which financial responsibility has been, or is expected to be, allocated.

LP’s estimates of its environmental loss contingencies do not reflect potential future recoveries from insurance carriers except to the extent that recovery may from time to time be deemed probable as a result of a carrier’s agreement to payment terms.

The activity in LP’s reserve for estimated environmental loss contingency reserves for the last three years is summarized in the following table.

ABT Hardboard Siding Matters

Between 1995 and 1999, ABT Building Products Corporation (“ABT”), ABTco, Inc., a wholly owned subsidiary of ABT (“ABTco” and, together with ABT, the “ABT Entities”), Abitibi-Price Corporation (“Abitibi”), a predecessor of ABT, and certain affiliates of Abitibi (the “Abitibi Affiliates” and, together with Abitibi, the “Abitibi Entities”) were named as defendants in numerous class action and non-class action proceedings brought on behalf of various persons or purported classes of persons (including nationwide classes in the United States and Canada) who own or have purchased or installed hardboard siding manufactured or sold by the defendants. In general, the plaintiffs in these actions have claimed unfair business practices, breach of warranty, fraud, misrepresentation, negligence, and other theories related to alleged defects, deterioration, or other failure of such hardboard siding, and seek unspecified compensatory, punitive, and other damages (including consequential damage to the structures on which the siding was installed), attorneys’ fees and other relief.

LP acquired ABT in February 1999 and ABT was merged into LP in January of 2001. On September 21, 2000, the Circuit Court of Choctaw County, Alabama, under the caption Foster, et al. v. ABTco, Inc., ABT Building Products Corporation, Abitibi-Price, Inc. and Abitibi-Price Corporation (No. CV95-151-M), approved a settlement agreement among the defendants and attorneys representing a nationwide class composed of all persons who own or formerly owned homes or, subject to limited exceptions, other buildings or structures on which hardboard siding manufactured by the defendants was installed between May 15, 1975 and May 15, 2000. Except for approximately 30 persons who timely opted out, the settlement includes and binds all members of the settlement class and resolves all claims asserted in the various proceedings described above. Under the settlement agreement, class members will have twenty-five years after their siding was installed to file a claim.

Under the settlement agreement, the defendants will be entitled to elect to make an offer of settlement to an eligible claimant based on the information set forth in the claim submitted by such claimant, and such claimant will be entitled to accept or reject the offer. If an eligible claimant declines the offer, or if no offer is made, such claimant will be entitled to a payment based on an independent inspection. Such payments will be based on a specified dollar amount (calculated on the basis of statewide averages and ranging from $2.65 to $6.21, depending upon the state) per square foot of covered siding that has experienced specified types of damage, subject to reduction based on the age of the damaged siding and any failure to paint the damaged siding within stated intervals (except in the case of damaged siding installed on mobile homes, as to which a uniform 50% reduction will apply in all circumstances). If applicable, payments under the settlement will also be subject to reduction to reflect any warranty payments or certain other payments previously recovered by a claimant on account of the damaged siding. Under the settlement agreement, LP (as a successor to ABT) will be required to pay the expenses of administering the settlement and certain other costs.

ABT and Abitibi were parties to an agreement of an allocation of liability with respect to claims related to siding sold prior to October 22, 1992. On June 13, 2001, in exchange for a cash payment from Abitibi of approximately $19.0 million which was received in July 2001, LPC, a wholly owned subsidiary of LP, agreed to accept a transfer of all of Abitibi’s rights and obligations under the settlement agreement and the allocation agreement; and LP and LPC agreed to indemnify and hold harmless Abitibi from any cost or liability arising from its sale of hardboard siding in the United States. From the date of the agreement, Abitibi has no further rights, obligations or liabilities under either the class action settlement agreement or the allocation agreement. All such rights, obligations and liabilities have been assigned to and accepted and assumed by LPC.

During 2011, LP increased its reserves in connection with this class action settlement. The additional reserves reflect revised estimates of undiscounted future claim payments and related administrative costs. During 2012 and 2013, LP decreased its reserves in connection with this settlement due to reductions in claims activity. LP believes that the reserve balance at December 31, 2013 will be adequate to cover future payments to claimants and related administrative costs. However, it is possible that additional charges may be required in the future.

The activity in the portion of LP’s loss contingency reserves relating to hardboard siding contingencies for the last three years is summarized in the following table. Included in this table for 2013 and 2012 are reimbursements received by LP from an insurance company for a portion of the claims payments and administrative costs covered under a court judgment related to production and sales of the specific products for specific years.

Other Proceedings

Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure [Text Block]

INVESTMENTS

Long-term investments held by LP are debt securities designated as available for sale and are reported at fair market value using the specific identification method. The following table summarizes unrealized gains and losses related to these investments as of December 31, 2013 and December 31, 2012:

Dollar amounts in millions	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Fair Value
December 31, 2013
Auction rate securities	$	0.4	$	3.3	$	—	$	3.7
Total marketable securities	$	0.4	$	3.3	$	—	$	3.7
December 31, 2012
Auction rate securities	$	0.3	$	1.7	$	—	$	2.0
Total marketable securities	$	0.3	$	1.7	$	—	$	2.0

As of December 31, 2013, LP had $3.7 million ($23.4 million, par value) invested in auction rate securities (ARS). The ARS held by LP are securities with long-term nominal maturities for which the interest rates may be reset through a Dutch auction each month. LP’s investments in ARS represent interests in collateralized debt obligations supported by pools of residential and commercial mortgages, bank trust preferred notes and other securities.

During 2011, LP sold $38.1 million (par value) of its ARS in an open market transaction for $19.1 million. LP recorded a gain on sale of securities of $15.2 million, which represents a recovery of losses previously recorded as an “Other-than-temporary impairment”.

LP reviews its marketable securities routinely for other-than-temporary impairment. The primary factors LP used to determine if an impairment charge must be recorded, because a decline in value of the security is other than temporary, include (i) whether the fair value of the investment is significantly below its cost basis, (ii) the financial condition of the issuer of the security (including its credit rating) and the underlying collateral, (iii) the length of time that the cost of the security has exceeded its fair value and (iv) LP’s intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in market value.

The contractual maturities of debt securities classified as available for sale at December 31, 2013 were as follows:

Dollar amounts in millions	2013
	Amortized Cost		Fair Value
Due in one year or less	$	—	$	—
Due in more than one year	0.4		3.7
Total marketable securities	$	0.4	$	3.7

Proceeds from sales and maturities of investments for the year ended December 31, 2011, totaled $19.1 million. There were no purchases of short-term and long-term investments for the years ended December 31, 2013, 2012, and 2011. During 2013, 2012 and 2011, LP did not own any short-term investments. Net unrealized gains and losses on derivative instruments are reported as a separate component of “Accumulated comprehensive loss” in Stockholders’ equity.

During 2012, LP's ARS litigation with Deutsche Bank Securities, Inc. was settled, which resulted in a gain of $20.0 million recorded in non-operating income (expense). (See Note 11 for further discussion)

Guarantees and Indemnifications

Commitments and Contingencies Disclosure [Abstract]

Guarantees and Indemnifications

GUARANTEES AND INDEMNIFICATIONS

LP is a party to contracts in which LP agrees to indemnify third parties for certain liabilities that arise out of or relate to the subject matter of the contract. In some cases, this indemnity extends to related liabilities arising out of the negligence of the indemnified parties, but usually excludes any liabilities caused by gross negligence or willful misconduct of the indemnified parties. LP cannot estimate the potential amount of future payments under these agreements until events arise that would trigger the liability.

Additionally, in connection with certain sales of assets and divestures of businesses, LP has agreed to indemnify the buyer and related parties for certain losses or liabilities incurred by the buyer or such related parties with respect to (1) the representations and warranties made to the buyer by LP in connection with the sales and (2) liabilities related to the pre-closing operations of the assets sold. Indemnities related to pre-closing operations generally include environmental liabilities, tax liabilities and other liabilities not assumed by the buyer.

Indemnities related to the pre-closing operations of sold assets normally do not represent added liabilities for LP, but simply serve to protect the buyer from potential liability associated with the obligations that existed (known and unknown) at the time of the sale. LP records accruals for those pre-closing obligations that are considered probable and estimable. LP is required to record a liability for the fair value of the guarantees that are entered into subsequent to December 31, 2002. LP has not accrued any additional amounts as a result of the indemnity agreements summarized below as LP believes the fair value of the guarantees entered into after December 31, 2002 is not material.

• In connection with various sales of LP’s timberlands, LP has agreed to indemnify various buyers with respect to losses resulting from breaches of limited representations and warranties contained in these agreements. These indemnities generally are capped at a maximum potential liability and have an unspecified duration.

• In connection with the sale of LP’s two inter-related interior hardboard facilities to Decorative Panels International Inc. in 2004, LP provided a 10-year indemnity for unknown environmental claims, capped at $4.0 million with a $0.3 million deductible. This indemnity will expire in May 2014.

• In connection with the sale by LP Canada Pulp Ltd (LPCP) of its pulp mill in Chetwynd, BC, Canada to Tembec, Ltd in October 2002, LP provided an indemnity of unspecified duration provided by LPCP for liabilities arising out of pre-closing operations. These indemnities, which do not extend to environmental liabilities, are capped at C$15.0 million in the aggregate.

LP also has various other indemnities that are individually and in the aggregate immaterial.

LP will record a liability related to specific indemnification when future payment is probable and the amount is estimable.

Additionally, LP offers warranties on the sale of most of its products and records an accrual for estimated future claims. Such accruals are based upon historical experience and management’s estimate of the level of future claims. The activity in warranty reserves for the last three years is summarized in the following table.

	Year ended December 31,
Dollar amounts in millions	2013			2012			2011
Beginning balance	$	21.4		$	30.3		$	29.5
Accrued to expense during the year	2.7			4.5			13.7
Credited to other operating credits and charges	17.7			(1.8		)	—
Payments made	(12.5		)	(11.6		)	(12.9		)
Total warranty reserves	29.3			21.4			30.3
Current portion	(12.0		)	(12.0		)	(12.0		)
Long term portion	$	17.3		$	9.4		$	18.3

The current portion of the warranty reserve is included in “Accounts payable and accrued liabilities” and the long-term portion is included in “Other long-term liabilities” on the Consolidated Balance Sheets.

During 2013, LP increased the warranty reserve associated with CanExel products sold in certain geographic areas by $17.7 million. The changes to the reserve reflected revised estimates of future claims.

During 2012, LP increased the warranty reserve related to its discontinued vinyl siding products by $3.6 million. The change to the reserve reflected revised estimates of future claims.

LP increased the warranty reserves related to discontinued composite decking products by $2 million in 2013 and $12 million in 2011. The additional reserves reflect revised estimates of future claim payments based upon an increase in decking warranty claims related to a specific operation and specific time period. During the fourth quarter of 2008, LP established a voluntary recall of the affected decking. During the second quarter of 2009, LP established a formal recall program under the Consumer Products Safety Board requirements for these products. No additional reserve increase was required in connection with the establishment of the formal program. LP continues to monitor warranty and other claims associated with these products and with the recall program (see Note 18) and believe as of December 31, 2013 that the reserves associated with these matters are adequate.

LP believes that the warranty reserve balances at December 31, 2013 are adequate to cover future warranty payments. However, it is possible that additional charges may be required.

(a) These accumulated other comprehensive income components are included in the computation of net periodic pension cost, see Note 13 for additional details. The net periodic pension cost is included in Cost of sales and Selling and administrative line items in the Consolidated Statements of Income.

Foreign currency translation adjustments exclude income tax expense (benefit) given that these adjustments arise out of the translation of assets into the reporting currency that is separate from the taxable income and is deemed to be reinvested for an indefinite period of time. The pension adjustments included income tax benefits of $15.5 million, $0.9 million and $14.1 million in 2013, 2012 and 2011.

Acquisition of Peace Valley OSB (Notes)

Acquisition of Peace Valley OSB [Abstract]

Business Combination Disclosure [Text Block]

24.    ACQUISITION OF PEACE VALLEY OSB

On May 31, 2013, LP acquired full control of the Peace Valley OSB joint venture in which LP previously maintained a 50% interest. Peace Valley OSB's results of operations have been fully consolidated in all periods subsequent to May 31, 2013. Since LP previously served as the exclusive distributor of all OSB produced by this venture, this acquisition will not have a material impact on LP's consolidated net sales.

Due to LP's pre-existing 50% ownership interest in Peace Valley OSB, this acquisition was accounted for as a step acquisition in accordance with ASC 805, Business Combinations (“ASC 805”). Accordingly, LP recognized a gain of $35.9 million in connection with this transaction to remeasure its 50% ownership interest in Peace Valley at fair value on the acquisition date. The gain is reflected in Other operating credits and charges, net on the Consolidated Statement of Income. The fair value of LP's existing 50% interest ($95.9 million) was determined using a combination of the income and market approach. In completing this valuation, management considered future earnings and cash flow potential of the business, earnings multiples, and recent market transactions of similar businesses. This gain is included in "Non-operating income (expense)."

The purchase price of the 50% acquired interest was $74.6 million (including working capital) paid in cash. Additionally, as part of the purchase consideration, LP agreed to pay contingent consideration equal to a pre-defined percentage of the operation's earnings before interest, taxes, depreciation and amortization (EBITDA) over a pre-defined threshold for each of the next three years. As of May 31, 2013, the fair value of the contingent consideration payable was valued at $24.3 million and was recorded in “accounts payable and accrued liabilities” and “other long term liabilities”. The fair value of the contingent consideration payable will be remeasured at the end of each reporting period. During the remainder of 2013, the fair value of the contingent consideration payable was remeasured and reduced by $20.5 million due to the decline in projected OSB prices in the near term as compared to the date of acquisition. This reduction in OSB results in a reduction in the estimated EBITDA of the operation.

Including the 50% interest previously owned by LP, LP acquired net assets of $194.8 million, consisting of $22.7 million in current assets, $146.4 million in fixed asset, $43.8 million of intangible assets (comprised of $34.1 million of timber licenses and $9.7 million of goodwill) and $8.7 million in current liabilities and $9.4 million in long term liabilities. Additional financial information about Peace Valley OSB (e.g., pro forma financial information and allocation of purchase price) is not presented because such information is not material to LP's results of operations and financial position.

Summary of Significant Accounting Policies

12 Months Ended

Dec. 31, 2013

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]

Significant Accounting Policies [Text Block]

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Louisiana-Pacific Corporation and its subsidiaries (collectively LP or the Company) are principally engaged in the manufacture of building products. In addition to its U.S. operations, the Company also maintains manufacturing facilities in Canada, Chile and Brazil through foreign subsidiaries and a joint venture. The principal customers for the Company’s building products are retail home centers, manufactured housing producers, distributors and wholesalers in North America and South America, with sales to Asia, Australia and Europe.

See Note 26 below for further information regarding LP’s products and segments.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. See discussion of specific estimates in this Note under the headings “Asset Impairments,” and “Other Operating Credits and Charges, Net” and in the Notes entitled “Income Taxes,” “Retirement Plans and Postretirement Benefits,” “Stockholders’ Equity,” “Other Operating Credits and Charges, Net,” “Gain (Loss) on Sale of and Impairment of Long-Lived Assets, Net,” “Contingencies” and "Acquisition of Peace Valley OSB."

Consolidation

The consolidated financial statements include the accounts of LP and its majority-owned subsidiaries after elimination of intercompany transactions. The equity method of accounting is used for joint ventures and investments in associated companies over which LP has significant influence but does not have control. Significant influence is deemed to exist generally when the Company has an ownership interest in the voting stock of an investee of between 20 percent and 50 percent. LP’s equity in the income and losses of these investments is recorded in “Equity in loss of unconsolidated affiliates” on the Consolidated Statements of Income. See Note 8 for further discussion of these investments and advances. Where our ownership interest is less than 100 percent but more than 50 percent, the outside shareholders’ interests are shown as non-controlling interest. See Note 19 for further discussion of this investment.

LP consolidates a variable interest entity (VIE) when it has a controlling financial interest in the VIE and is thus determined to be the VIE's primary beneficiary. LP currently consolidates its interest in LP Pinewood which was established in 2003 in connection with the sale of LP's southern timberlands. LP has notes receivable of $410.0 million (see Note 6) and notes payable of $368.7 million (see Note 12) recorded in the balance sheet related to LP's interest in the VIE. For further information regarding the details of the relationship of the assets and liabilities and the recourse provisions of the consolidated VIE see Note 12.

LP also has a variable interest in its Abitibi-LP equity method investee but is not considered to be the primary beneficiary. See Note 8 for further information on this investment.

Earnings per Share

Basic earnings per share are based on the weighted-average number of shares of common stock outstanding. Diluted earnings per share are based upon the weighted-average number of shares of common stock outstanding plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. This method requires that the effect of potentially dilutive common stock equivalents (employee stock options, stock settled stock appreciation rights, incentive shares, performance shares and warrants) be excluded from the calculation of diluted earnings per share for the periods in which losses from continuing operations are reported because the effect is anti-dilutive. The following table sets forth the computation of basic and diluted earnings per share:

	Year ended December 31,
Dollar and share amounts in millions, except per share amounts	2013			2012			2011
Numerator:
Income (loss) attributed to LP common shares:
Income (loss) from continuing operations	$	177.4		$	29.5		$	(175.7	)
Loss from discontinued operations	(0.3		)	(0.7		)	(5.6		)
Net income (loss)	$	177.1		$	28.8		$	(181.3	)
Denominator:
Basic—weighted average common shares outstanding	139.6			137.1			133.2
Dilutive effect of employee stock plans	2.5			2.3			—
Dilutive effect of stock warrants	2.2			3.2			—
Diluted shares outstanding	144.3			142.6			133.2
Basic earnings per share:
Income (loss) from continuing operations	$	1.27		$	0.22		$	(1.32	)
Loss from discontinued operations	—			(0.01		)	(0.04		)
Net income (loss) per share	$	1.27		$	0.21		$	(1.36	)
Diluted earnings per share:
Income (loss) from continuing operations	$	1.23		$	0.20		$	(1.32	)
Loss from discontinued operations	—			—			(0.04		)
Net income (loss) per share	$	1.23		$	0.20		$	(1.36	)

Stock options, warrants and stock settled stock appreciation rights (SSARs) related to approximately 2.3 million and 5.3 million common shares were considered not in-the-money for purposes of LP's earnings per share calculation for the years ended December 31, 2013 and 2012. Stock options, warrants and stock settled stock appreciation rights (SSARs) related to approximately 7.1 million common shares for the year ended December 31, 2011 were considered anti-dilutive for purposes of LP’s earnings per share calculation due to LP’s loss position in continuing operations.

Cash and Cash Equivalents

Cash and cash equivalents consist of money market investments with an initial maturity of three months or less. These investments are stated at cost, which approximates market value.

Investments

LP’s long-term investments are classified as available-for-sale and are reported at estimated fair value. LP may invest in securities including U.S. treasury notes, bank obligations, corporate obligations, auction rate securities and commercial paper. Under LP’s investment criteria at purchase, bank and corporate obligations carry a rating of at least A-1 and commercial paper must have the highest rating obtainable from one or more rating agencies. Unrealized gains and losses, net of tax, on these investments are reported as a separate component of “Accumulated comprehensive loss” in Stockholders’ Equity until realized. Impairment losses are charged to income for other-than-temporary declines in fair value. Realized gains and losses (including impairments) are recorded in “Investment income” in the Consolidated Statements of Income. For purposes of computing realized gains and losses, cost is identified on a specific identification basis. See Note 2 for further discussion.

Fair Value of Financial Instruments

LP has, where appropriate, estimated the fair value of financial instruments. These fair value amounts may be significantly affected by the assumptions used, including the discount rate and estimates of cash flows. Accordingly, the estimates presented are not necessarily indicative of the amounts that could be realized in a current market exchange.

Inventory

Inventories are valued at the lower of cost or market. Inventory costs include materials, labor and operating overhead. The LIFO (last-in, first-out) method is used for a minor portion of the Company’s log inventories with the remaining inventories valued at FIFO (first-in, first-out) or average cost. See Note 5 for further discussion.

Timber and Timberlands

Timber and timberlands is comprised of timber deeds and allocations of purchase price to Canadian timber harvesting licenses. Timber deeds are transactions in which LP purchases timber, but not the underlying land. The cost of timber deeds are capitalized in timber and timberlands and charged to cost of timber harvested as the volume is removed. Timber that has been severed but has not yet been delivered to a facility is included in timber and timberlands. The values associated with timber licenses were allocated in the purchase price allocations for Le Groupe Forex (Forex), Peace Valley OSB and the assets of Evans Forest Products. These licenses have a life of twenty to twenty-five years. These licenses are amortized on a straight-line basis over the life of the facilities. Cost of timber harvested also includes the amortization of the timber licenses. See Note 7 for further discussion.

Assets Held for Sale

Over the last several years, LP has adopted and implemented plans to sell selected assets in order to improve its operating results. LP is required to classify assets held for sale which are not part of a discontinued business separately on the face of the financial statements outside of “Property, plant and equipment”. As of December 31, 2013 and 2012, LP included two OSB mills and various non-operating sites in its held for sale category. See Note 3 for discussion of impairments recorded on these assets to reduce carrying value to estimated sales prices less estimated selling costs. During 2013, assets held for sale of $14.9 million were reclassified to assets held and used, due to a change in the plan of sale. The 2012 disclosure below was updated to reflect this change. The current book values of assets held for sale by category is as follows:

Dollar amounts in millions	December 31,
	2013			2012
Property, plant and equipment, at cost:
Land, land improvements and logging roads, net of road amortization	$	6.9		$	7.1
Buildings	6.2			7.8
Machinery and equipment	99.1			99.7
	112.2			114.6
Accumulated depreciation	(95.9		)	(97.0		)
Net property, plant and equipment	$	16.3		$	17.6

LP believes that the net realizable sales value of the aforementioned assets exceeds their carrying values.

Property, Plant and Equipment

Property, plant and equipment, including capitalized interest, are recorded at cost. Depreciation for financial statement purposes is provided principally using the units of production method for machinery and equipment which amortizes the cost of equipment over the estimated units that will be produced during its useful life. Provisions for depreciation of buildings, land improvements and the remaining machinery and equipment have been computed using straight-line rates based on the estimated service lives. The effective straight-line lives for the principal classes of property range from three to twenty years.

Logging road construction costs are capitalized and included in land and land improvements. These costs are amortized as the timber volume adjacent to the road system is harvested.

LP capitalizes interest on borrowed funds during construction periods. Capitalized interest is charged to machinery and equipment accounts and amortized over the lives of the related assets. Capitalized interest totaled $1.6 million in 2013 and $0.2 million in 2012.

Potential Impairments

Long-lived assets to be held and used by LP (primarily property, plant and equipment and timber and timberlands) are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. When impairment is indicated, the book values of the assets are written down to their estimated fair value as calculated by the expected discounted cash flow or estimated net sales price. See Note 3 for impairment charges recorded in the periods presented. See Note 17 for a discussion of charges in 2013, 2012 and 2011 related to impairments of property, plant and equipment. Long-lived assets that are held for sale are written down to the estimated sales proceeds less cost to sell unless the estimated net proceeds exceed the carrying value.

LP continues to review certain operations and investments for potential impairments. LP’s management currently believes it has adequate support for the carrying value of each of these operations and investments based upon the anticipated cash flows that result from estimates of future demand, pricing and production costs assuming certain levels of planned capital expenditures. As of December 31, 2013, the fair values of LP's facilities were substantially in excess of their carrying value, which supported the conclusion that no impairment is necessary for those facilities. However, if demand and pricing for the relevant products continues at levels significantly below cycle average demand and pricing, or should LP decide to invest capital in alternative projects, it is possible that impairment charges will be required.

Income Taxes

LP accounts for income taxes under an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in LP’s financial statements or tax returns. In estimating future tax consequences, LP generally considers all expected future events other than the enactment of changes in tax laws or rates and future income. The effect on deferred tax assets and liabilities of a change in tax rates will be recognized as income or expense in the period that includes the enactment date. Additionally, deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion of the deferred tax assets will not be realized.

LP recognizes liabilities for uncertain tax positions through a two step process. The first step is to the evaluate the tax position for recognition by determining if the weight of the available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation process, if any. The second step requires LP to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as LP must determine the probability for various outcomes. LP evaluates these uncertain tax provisions when new information becomes available. These revaluations are based upon factors including, but not limited to, changes in circumstances, changes in tax law, successful settlement of issues under audit and new audit activity. Such a change in recognition or measurement could result in the recognition of a tax benefit or an increase to the related provision.

LP classifies interest related to income taxes liabilities or uncertain tax positions as interest expense or interest income and, if applicable, penalties are recognized as a component of income tax expense.

See Note 10 for further discussion of deferred taxes.

Stock-Based Compensation

LP recognizes the cost of employee services received in exchange for awards of equity instruments, such as stock options, performance shares, restricted stock or restricted stock units and stock settled stock appreciation rights (SSAR), based upon the fair value of those awards at the date of grant over the requisite service period. LP generally uses the Black-Scholes-Merton (Black-Scholes) option pricing model to determine the fair value of the stock option and SSAR awards. Stock-based compensation plans, related expenses and assumptions used in the Black-Scholes option pricing model are more fully described in Note 14. The fair market value of performance share awards are determined based on the fair value as of the date of grant times the number of shares adjusted for the weighted probability of the attainment of the relevant performance goals.

Derivative Financial Instruments

To reduce foreign currency exchange and interest rate risks, LP occasionally utilizes derivative financial instruments, which include forward exchange, options and futures contracts. For the years ended December 31, 2013, 2012 and 2011, LP did not enter into any material derivative financial contracts.

Foreign Currency Translation

The functional currency for the Company’s Canadian subsidiaries is the U.S. dollar; however the books and records for these subsidiaries are maintained in the Canadian dollar. The financial statements of these foreign subsidiaries are remeasured into U.S. dollars using the historical exchange rate for property, plant and equipment, timber and timberlands, goodwill, and certain other non-monetary assets and related depreciation and amortization on these assets and liabilities. LP uses the exchange rate at the balance sheet date for the remaining assets and liabilities, including deferred taxes. A weighted-average exchange rate is used for each period for revenues and expenses. These transaction gains or losses are recorded in “Other non-operating income (expense)” on the Consolidated Statements of Income.

The functional currencies of LP’s Chilean, Brazilian and Peruvian subsidiaries are the Chilean peso, Brazilian real and Peruvian nuevo sol and their books and records are maintained in the local currency. Translation adjustments, which are based upon the exchange rate at the balance sheet date for assets and liabilities and the weighted-average rate for the income statement, are recorded in “Accumulated comprehensive loss” in Stockholders’ equity.

Goodwill

Goodwill is tested for impairment on an annual basis, and when indicators of impairment are determined to exist. Impairment is evaluated by applying a fair value based test. Impairment losses would be recognized whenever the implied fair value of goodwill is less than its carrying value.

Intangible Assets

Intangible assets with finite useful lives are amortized generally on a straight-line basis over the periods benefited. Impairment of the intangible asset is evaluated when factors indicate impairment may exist.

Restricted Cash

In accordance with LP’s credit facilities, discussed at Note 12, LP has established restricted cash accounts. As of December 31, 2013, a portion of the restricted cash secures outstanding letters of credit under LP’s U.S. and Canadian credit facilities.

Revenue Recognition

Revenue is recognized when customers receive products and title has passed. The following criteria are used to determine that title has passed: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the price to the buyer is fixed or determinable; and (4) the collection is reasonably assured.

During 2013, 2012 and 2011, LP's top ten customers accounted for approximately 44%, 46% and 48% of its sales. During 2012, Home Depot, Inc. accounted for more than 10% of its sales with no customers exceeding 10% in 2013 or 2011.

Pricing and Sales Incentives

LP records estimated reductions to revenue for customer programs and incentive offerings, including pricing arrangements, promotions and other volume-based incentives, at the date revenue is recognized. Some of these incentives are negotiated up front with the customer and are redeemable only if the customer achieves a specified cumulative level of sales (measured in dollars or units) or sales increase. Under these incentive programs, at the time of sale, LP estimates the anticipated rebate to be paid based upon forecasted sales levels. These forecasts are updated on a regular basis. If the forecasted sales for a customer change significantly, the accrual for rebates is adjusted to reflect the revised estimate.

Asset Retirement Obligations

LP records the fair value of the legal obligations and the conditional obligations to retire and remove long-lived assets in the period which the obligation is incurred. These obligations primarily consist of monitoring costs on closed landfills, timber reforestation obligations associated with LP’s timber licenses in Canada and certain site restoration costs. When the related liability is initially recorded, LP capitalizes the cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its settlement value and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, LP recognizes a gain or loss for any difference between the settlement amount and the liability recorded. See Note 15 for further discussion.

Deferred Debt Costs

Deferred debt costs are amortized over the life of the related debt using a straight line basis which approximates the effective interest method. If the debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired to other non-operating income (expense). During 2013, $1.4 million and during 2012, $4.5 million of deferred debt costs were written off in association with the early debt extinguishment. LP amortized deferred debt costs of $1.4 million, $1.5 million and $2.6 million for the years ended December 31, 2013, 2012 and 2011. See Note 11 for further discussion.

Other Operating Credits and Charges, Net

LP classifies significant amounts that management considers unrelated to ongoing core operating activities as “Other operating credits and charges, net” in the Consolidated Statements of Income. Such items include, but are not limited to, amounts related to restructuring charges (including severance charges), charges to establish and maintain litigation or environmental reserves, product reserves, prior year inventory profit adjustments, retirement charges and gains or losses from settlements with governmental or other organizations. Due to the nature of these items, amounts in the income statement can fluctuate from year to year. The determination of which items are considered significant and unrelated to core operations is based upon management’s judgment. See Note 16 for a discussion of specific amounts in 2013, 2012 and 2011.

Retirement Benefits

LP is required to use actuarial methods and assumptions in the valuation of defined benefit obligations and the determination of expense. Difference between actual and expected results or changes in the values of the obligations and plan assets are not recognized in earnings as they occur but, rather, systematically and gradually over subsequent periods. See Note 13 for further information.

Comprehensive Income

Comprehensive income consists of net income (loss) and other gains and losses affecting shareholders’ equity that are excluded from net income (loss), including foreign currency translation adjustments, prior service costs and credits, transition assets or obligations associated with pension or other post retirement benefits that have not been recognized as components of net periodic benefit costs, net unrealized gains or losses on securities, and unrealized gains and losses on financial instruments qualifying for cash flow hedge accounting, and is presented in the accompanying Consolidated Statements of Comprehensive Income. See Note 23 for further discussion.

Present and Prospective Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02 "Reporting of Amounts Reclassified Out of Accumulated Comprehensive Income." The amendment does not change the current requirement for reporting net income or other comprehensive income in financial statements; however, the amendment requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The new disclosure requirements were effective for all periods beginning after December 15, 2012. The adoption of the amendments impacts presentation only and did not have an effect on LP’s financial condition, results of operations or cash flows. See Note 23 for further discussion.

Proposed Acquisition of Ainsworth (Notes)

12 Months Ended

Dec. 31, 2013

Proposed Acquisition of Ainsworth [Abstract]

Proposed Acquisition [Text Block]

25.    PROPOSED ACQUISITION OF AINSWORTH LUMBER CO. LTD.

In September of 2013 LP entered into an Arrangement Agreement (the “Arrangement”) with Ainsworth Lumber Co. Ltd., a British Columbia corporation (“Ainsworth”), providing an arrangement under British Columbia law whereby a wholly owned subsidiary of the Company will acquire all of the outstanding shares of Ainsworth capital stock in exchange for 0.114 shares of LP common stock (“LP Shares”) and C$1.94 in cash per Ainsworth common share (“Ainsworth Shares”) subject to certain terms and conditions. Although the Arrangement provides for Ainsworth shareholders to elect among cash consideration, share consideration and mixed consideration, proration provisions will ensure that the aggregate amounts of cash and LP Shares issued in the Transaction are fixed at approximately C$467.0 million and 27.5 million LP Shares, respectively.

The requisite approvals of the Transaction by Ainsworth shareholders and the Supreme Court of British Columbia were obtained on October 29, 2013 and October 31, 2013, respectively. As of the date of this report, the consummation of the Transaction remained subject to other closing conditions, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the receipt of other regulatory approvals and clearances, including under the Canadian Competition Act and the Investment Act of Canada. LP and Ainsworth have agreed to endeavor to cause all closing conditions (including the receipt of regulatory approvals) to be satisfied, which under certain circumstances could require the taking of actions that could adversely affect the value of the Transaction to us.

On February 13, 2014, Ainsworth and LP announced that they have entered into timing agreements with each of the Canadian Competition Bureau (the “CCB”) and the Antitrust Division of the U.S. Department of Justice (the “DOJ”) pursuant to which Ainsworth and LP have agreed, subject to certain conditions, that they will not consummate LP’s acquisition of Ainsworth before March 13, 2014 as the CCB and the DOJ continue their reviews.

As a consequence of the timing agreements described above, Ainsworth and LP also announced that they have agreed to extend the outside date for completion of the Arrangement from March 4, 2014 to April 18, 2014. The Arrangement permits either party to further extend the outside date for two additional 45 day periods if required to obtain certain regulatory approvals.

The closing of the Arrangement remains subject to a number of conditions, including the expiration or termination of the waiting period under the HSR Act and the receipt of other regulatory approvals and clearances including under the Canadian Competition Act. Subject to obtaining required regulatory approvals and clearances and the satisfaction or waiver of other closing conditions, it is now anticipated that the Arrangement will be completed before the end of the second quarter of 2014.

The Arrangement contains certain termination rights for each of LP and Ainsworth. Either party may terminate the Arrangement Agreement if: (i) the parties mutually agree; (ii) the Transaction has not been consummated by March 31, 2014 (subject to extension in certain circumstances); (iii) a governmental authority issues a law or order prohibiting the Transaction; (iv) the other party materially breaches its representations, warranties or covenants such that the applicable closing condition would not to be satisfied; or (v) the other party has incurred a Material Adverse Effect (as defined in the Arrangement Agreement).

LP expects to fund the purchase price payable in the Transaction and related fees and expenses through a combination of cash on hand at LP and Ainsworth and borrowings under our revolving credit facility. The obligations of the lenders to provide debt financing under the debt commitments are subject to customary conditions.

On October 17, 2013, Ainsworth issued a press release announcing that it had received the requisite consents in connection with its consent solicitation (the "Consent Solicitation") from holders of Ainsworth's 7.5% Senior Secured Notes due 2017 (the "Notes") . The press release also announced that Ainsworth has entered into a supplemental indenture relating to the Notes, which modified certain definitions in the indenture relating to the Notes (the "Indenture") so that the consummation of the Transaction pursuant to the Arrangement Agreement, and the designation by LP of members of Ainsworth’s board of directors upon and after the consummation of the Transaction, will not constitute a “Change of Control” under the Indenture and Ainsworth will not be required to make a “Change of Control Offer” under the Indenture in connection with the Transaction. Subject to the satisfaction or waiver of the conditions set forth in the solicitation statement distributed by Ainsworth to holders of the Notes, LP will make the consent payments contemplated thereby as and when they become due. Promptly following the consummation of the Transaction, LP will unconditionally guarantee the prompt payment and performance of the obligations of Ainsworth under the Indenture and the Notes.

The Transaction is expected to have a material effect on LP’s consolidated financial position, results of operations and cash flows. For additional information, see the Ainsworth Lumber Co. Ltd. Notice of Special Meeting and Management Proxy Circular furnished as Exhibit 99.1 to LP's Current Report on Form 8-K dated September 30, 2013.

LP received income tax refunds during 2013, 2012 and 2011 of $0.9 million, $1.9 million and $25.8 million and paid cash taxes of $6.8 million, $1.6 million and $0.8 million. Included in the Consolidated Balance Sheet at December 31, 2013 and 2012 are income tax receivables of $1.2 million and $1.8 million.

The income tax effects of LP’s share of the income or loss of U.S. GreenFiber and Canfor-LP OSB Limited Partnership in 2013, 2012 and 2011 are recorded in “Provision (benefit) for income taxes” on the Consolidated Statements of Income, while LP’s share of such pre-tax income is recorded in “Equity in (income) loss of unconsolidated affiliates”.

The tax effects of significant temporary differences creating deferred tax (assets) and liabilities at December 31 were as follows:

	December 31,
Dollar amounts in millions	2013			2012
Property, plant and equipment	$	178.9		$	148.5

Long-term deferred tax asset	—			(5.0		)
Long-term deferred tax liability	188.7			93.6
	$	137.8		$	76.3

The $97.1 million of benefit relating to capital loss and net operating loss (NOL) carryovers included in the above table at December 31, 2013 consists of $3.4 million for federal NOL carryovers which will begin to expire in 2031, $30.5 million (net of federal taxes) for state NOL carryovers and $0.8 million for state capital losses which will expire in various years 2014 through 2032, $50.5 million for Canadian NOL carryovers which will expire starting in 2029 and $11.9 million for Canadian capital loss carryovers which may be carried forward indefinitely. At December 31, 2013, LP has recorded valuation allowances of $8.8 million related to state NOL carryover benefit; $0.8 million related to state capital loss carryover; $11.9 million against the Canadian capital loss benefit; $0.9 million against the state tax credit carryovers and $1.1 million related to other items.

LP periodically reviews the need for valuation allowances against deferred tax assets and recognizes these deferred tax assets to the extent that their realization is more likely than not. As part of our review, we consider all positive and negative evidence, including earnings history, the future reversal of deferred tax liabilities, and the relevant expirations of carry forwards. In 2013 we reversed the valuation allowance that had been previously recorded primarily against our state and Canadian deferred tax assets by approximately $22.1 million based on current operating results and an increase in deferred tax liabilities. Additionally, in the fourth quarter we reduced the valuation allowance by $5.1 million based on recent positive earnings history and trends and generally improving economic conditions. If future years’ earnings differs from the estimates used to establish these valuation allowances, LP may be required to record an adjustment resulting in an impact on tax expense (benefit) for that period.

As a result of certain realization requirements of ASC 718 Compensation --Stock Compensation, the table of deferred tax assets and liabilities shown above does not include $13.2 million and $3.7 million of deferred tax assets as of December 31, 2013 and December 31, 2012 that arose directly from tax deductions related to amounts of equity compensation that are greater than the compensation recognized for financial reporting. Equity will be increased if and when such deferred tax assets are ultimately realized. LP uses the "with and without" method for determining when excess tax benefits have been realized. In 2013 and 2011, LP recognized a current tax benefit of $0.3 million and a current tax cost of $0.6 million as adjustments to additional paid in capital arising from tax deductions for equity compensation that were more or less than the compensation recognized for financial reporting.

U.S. taxes have not been provided on approximately $47.2 million of undistributed earnings of LP’s foreign subsidiaries, which under existing law are not subject to U.S. tax until distributed as dividends. These earnings have been, and are intended to be, indefinitely reinvested in LP’s foreign operations. Determination of the amount of any unrecognized income tax liability on this temporary difference is not practical because of the complexities of the hypothetical calculation. Furthermore, any taxes paid to the foreign governments on these earnings may be used, in whole or in part, as credits against the U.S. tax on any dividends distributed from such earnings.

The following table summarizes the differences between the statutory U.S. federal and effective income tax rates on continuing operations:

	Year ended December 31,
	2013		2012		2011
U.S. Federal tax rate	35	%	35	%	(35	)%
State and local income taxes	2		2		(3	)

LP and its domestic subsidiaries are subject to U.S. federal income tax as well as income taxes of multiple state jurisdictions. Its foreign subsidiaries are subject to income tax in Canada, Chile, Peru and Brazil. During 2011, the U.S. Internal Revenue Service initiated an audit of tax years 2007 through 2009 for which field work has been completed. LP has protested certain proposed adjustments and requested review by the IRS Appeals Office. During 2013, LP deposited $17.1 million with the IRS to suspend the accrual of interest pending the resolution of this matter. The deposit is included within Other assets on the Consolidated Balance Sheet. All U.S. federal audits of prior years have been completed. During 2013, LP settled all of its open state income tax audits and remains subject to various state and local income tax examinations for the tax years 2007 through 2012. Canadian federal income tax years are closed 2008 and no examinations are currently in progress. Quebec provincial audits have been effectively settled through 2011 and 2012 is currently under review. During 2012, the Chilean Tax Office initiated an audit of the 2011 tax year.

On September 13, 2013, the U.S. Treasury Department and the IRS issued final regulations that address costs incurred in acquiring, producing, or improving tangible property (the "tangible property regulations"). The tangible property regulations are generally effective for tax years beginning on or after January 1, 2014, and may be adopted in earlier years.  We have considered the effect of these tax law changes to our deferred tax assets and liabilities and do not expect their implementation to have a material impact on our consolidated financial statements.

In accordance with the accounting for uncertain tax positions, the following is a tabular reconciliation of the total amount of unrecognized tax benefits at the beginning and end of the years presented:

	December 31,
Dollar amounts in millions	2013			2012			2011
Beginning balance	$	49.9		$	23.5		$	11.3
Increases:
Tax positions taken in current year	—			0.1			—
Tax positions taken in prior years	0.4			33.9			12.9
Decreases:
Tax positions taken in current year	—			—			(0.3		)
Tax positions taken in prior years	—			(7.4		)	(0.2		)
Settlements during the year	—			(0.2		)	(0.2		)
Lapse of statute in current year	(1.4		)	—			—
Ending balance	$	48.9		$	49.9		$	23.5

Included in the above balances at December 31, 2013 and 2012 is $12.8 million and $11.9 million of tax benefits that, if recognized, would affect LP’s effective tax rate. LP accrued interest of $0.2 million and $1.8 million during 2013 and 2012, and in total LP has recognized a liability of $5.7 million and $5.5 million for accrued interest related to its uncertain tax positions as of December 31, 2013 and 2012. LP's conference with the IRS Appeals office is scheduled for the first half of 2014. While outcomes and timing cannot be predicted, it is possible that unrecognized tax benefits of up to $42.8 million, primarily related to the timing of fixed asset recovery, could change significantly as a result of these conferences during the next twelve months.

LP believes the carrying amounts of its variable rate long-term debt approximates fair market value. LP estimated the limited recourse notes payable to have a fair value of approximately $23 million and $114 million at December 31, 2013 and 2012. LP estimated the senior unsecured notes maturing in 2020 to have a fair value of $390 million at December 31, 2013 and $397 million at December 31, 2012 based upon market quotations. LP believes the carrying amounts of the Chilean term credit facility as well as the Brazil export facility approximates fair market value based upon current interest rates with similar remaining maturities.

LP issued $348.6 million of senior notes in June 1998 in a private placement to institutional investors. The remaining $22.0 million of notes mature in 2018. A principal payment of $90.0 million was made on the notes during 2013. The notes are secured by $22.2 million of notes receivable from Green Diamond Resource Company (Green Diamond). Pursuant to the terms of the notes payable, in the event of a default by Green Diamond, LP would be liable to pay only 10% of the indebtedness represented by the notes payable.

LP issued $368.7 million of non-recourse notes in 2003 in a private placement to unrelated third parties. The notes mature in 2018. The notes are supported by a bank letter of credit. LP’s reimbursement obligations under the letter of credit are secured by $410.0 million in notes receivable from assets sales. In general, the creditors under this arrangement have no recourse to LP’s assets, other than the notes receivable. However, under certain circumstances, LP may be liable for certain liabilities (including liabilities associated with the marketing or remarketing of the notes payable and reimbursement obligations, which are fully cash collateralized, under the letter of credit supporting the notes payable) in an amount not to exceed 10% of the aggregate principle amount of the notes receivable.

In December 2013, LP entered into a credit agreement with various lenders and American AgCredit, PCA, as administrative agent and CoBank, ACB, as letter of credit issuer. The credit agreement provides for a $200 million revolving credit facility, with a $60 million sublimit for letters of credit. The credit facility terminates and all loans made under the credit agreement become due in December 2018. As of December 31, 2013, no revolving borrowings had been made under the credit facility.

Certain of LP’s existing and future wholly owned domestic subsidiaries guaranty LP’s obligations under the credit facility. Subject to certain limited exceptions, obligations under the credit facility are secured by a lien on substantially all of the personal property of LP and its subsidiaries that are guarantors under the credit facility.

Revolving borrowings under the credit agreement accrue interest, at the Company’s option, at either a “base rate” plus a margin of 0.75% to 2.50% or LIBOR plus a margin of 1.75% to 3.50%. The credit agreement also includes an unused commitment fee, due quarterly, ranging from 0.30% to 0.625%. The applicable margins and fees within these ranges are based on the Company’s ratio of consolidated EBITDA to cash interest charges. The “base rate” is the highest of (i) the Federal funds rate plus 0.5%, (b) the U.S. prime rate, and (iii) one month LIBOR plus 1.0%.

The credit agreement contains various restrictive covenants and customary events of default. The credit agreement also contains financial covenants that require the Company and its consolidated subsidiaries to have, as of the end of each quarter, (i) a capitalization ratio (i.e., funded debt to total capitalization) of no more than 40% and (ii) unrestricted cash and cash equivalents of at least (a) $350,000,000 until closing of the the Company’s acquisition of Ainsworth Lumber Co. Ltd. and (b) $250,000,000 thereafter, in each case calculated in the manner specified in the credit agreement. As of December 31, 2013, we were in compliance with all financial covenants under the credit agreement.

In December 2009, LP Chile entered into a term loan agreement with Banco de Credito e Inversiones for UF 943,543.7391 (equivalent to $39 million at the time of inception). The loan will be repaid in 16 semi-annual principal payments that began in June 2012 and end in December 2019. The loan bears interest at UF plus 3.90% per annum, and is partially secured by a first priority security interest in substantially all of the real property owned by LP Chile. The loan contains various restrictive covenants and requires the maintenance by LP Chile of a debt to equity ratio of less than or equal to 1. If LP Chile is late in making payments, it will also be required to maintain a ratio of net debt to earnings before interest, taxes, depreciation and amortization (EBITDA) of less than or equal to 2.5 and a ratio of EBITDA to financial costs of at least 3. The loan agreement also contains customary events of default, the occurrence of which could result in acceleration of LP’s obligations to repay the indebtedness outstanding. Any increases or decreases in the loan balance shown are related to the change in the underlying foreign currency exchange rates, the UF or principal payments. LP made principal payments of $21.0 million during 2013 which included a scheduled payment of $2.6 million and an optional prepayment of $18.4 million. The impact of foreign currency exchange rates in 2013 was $2.8 million which was offset by a UF change of $0.3 million. LP made principal payments of $5.5 million during 2012 which was offset by a UF change of $1.0 million plus the impact of foreign currency exchange rates of $3.2 million.

In August 2011, LP entered into an export financing loan agreement with a Brazilian bank. This loan is to be repaid in 10 equal semi-annual payments that began in January 2013 and end in July 2017. During 2013, LP made principal payments of $2.0 million.

In May 2012, LP issued $350.0 million of 7.5% Senior Notes due 2020. LP used a portion of the proceeds to fully retire the remaining balance outstanding on the Senior Secured Notes due in 2017. In connection with this repurchase, LP recorded a loss on early debt extinguishment of $52.2 million which included $4.5 million associated with the unamortized financing costs associated with the Senior Secured Notes. On or after June 1, 2016, LP may, at its option on one or more occasions, redeem all or any portion of the Notes at specified redemption rates.

Obligations under the indenture governing LP's Senior Notes due 2020 are unsecured and not presently guaranteed by any of its subsidiaries. The indenture contains customary covenants applicable to LP and its subsidiaries, other than certain unrestricted subsidiaries, including restrictions on actions and activities that are restricted under the credit facility. The indenture also contains customary events of default, the occurrence of which could result in acceleration of LP's obligations to repay the indebtedness outstanding thereunder.

The weighted average interest rate for all long-term debt at December 31, 2013 and 2012 was approximately 3.9 percent and 4.2 percent. Required repayment of principal for long-term debt is as follows:

At December 31, 2013, LP has an investment in a joint venture with Resolute Forest Products (formerly Abitibi-Bowater) to operate jointly owned I-Joist facilities in Quebec. Each partner owns 50% of the venture. In 2013, LP acquired full ownership of the Peace Valley OSB joint venture (formerly referred to as Canfor-LP) in which LP previously maintained a 50% interest (see Note 24 for further information). Additionally, during 2013, LP sold its equity investment in U.S. Greenfiber, which resulted in a gain of $1.2 million.

The remaining investment does not meet the Regulation S-X significance test requiring the inclusion of the separate investee financial statements; however based upon the aggregation requirements under S-X, aggregated summarized financial information (including net sales and net income information for entities no longer held) is required as follows:

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2013

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]

Nature of Operations [Policy Text Block]

Nature of Operations

Louisiana-Pacific Corporation and its subsidiaries (collectively LP or the Company) are principally engaged in the manufacture of building products. In addition to its U.S. operations, the Company also maintains manufacturing facilities in Canada, Chile and Brazil through foreign subsidiaries and a joint venture. The principal customers for the Company’s building products are retail home centers, manufactured housing producers, distributors and wholesalers in North America and South America, with sales to Asia, Australia and Europe.

See Note 26 below for further information regarding LP’s products and segments.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. See discussion of specific estimates in this Note under the headings “Asset Impairments,” and “Other Operating Credits and Charges, Net” and in the Notes entitled “Income Taxes,” “Retirement Plans and Postretirement Benefits,” “Stockholders’ Equity,” “Other Operating Credits and Charges, Net,” “Gain (Loss) on Sale of and Impairment of Long-Lived Assets, Net,” “Contingencies”

Consolidation, Policy [Policy Text Block]

Consolidation

The consolidated financial statements include the accounts of LP and its majority-owned subsidiaries after elimination of intercompany transactions. The equity method of accounting is used for joint ventures and investments in associated companies over which LP has significant influence but does not have control. Significant influence is deemed to exist generally when the Company has an ownership interest in the voting stock of an investee of between 20 percent and 50 percent. LP’s equity in the income and losses of these investments is recorded in “Equity in loss of unconsolidated affiliates” on the Consolidated Statements of Income. See Note 8 for further discussion of these investments and advances. Where our ownership interest is less than 100 percent but more than 50 percent, the outside shareholders’ interests are shown as non-controlling interest. See Note 19 for further discussion of this investment.

LP consolidates a variable interest entity (VIE) when it has a controlling financial interest in the VIE and is thus determined to be the VIE's primary beneficiary. LP currently consolidates its interest in LP Pinewood which was established in 2003 in connection with the sale of LP's southern timberlands. LP has notes receivable of $410.0 million (see Note 6) and notes payable of $368.7 million (see Note 12) recorded in the balance sheet related to LP's interest in the VIE. For further information regarding the details of the relationship of the assets and liabilities and the recourse provisions of the consolidated VIE see Note 12.

LP also has a variable interest in its Abitibi-LP equity method investee but is not considered to be the primary beneficiary. See Note 8 for further information on this investment.

Earnings Per Share, Policy [Policy Text Block]

Earnings per Share

Basic earnings per share are based on the weighted-average number of shares of common stock outstanding. Diluted earnings per share are based upon the weighted-average number of shares of common stock outstanding plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. This method requires that the effect of potentially dilutive common stock equivalents (employee stock options, stock settled stock appreciation rights, incentive shares, performance shares and warrants) be excluded from the calculation of diluted earnings per share for the periods in which losses from continuing operations are reported because the effect is anti-dilutive. The following table sets forth the computation of basic and diluted earnings per share:

	Year ended December 31,
Dollar and share amounts in millions, except per share amounts	2013			2012			2011
Numerator:
Income (loss) attributed to LP common shares:
Income (loss) from continuing operations	$	177.4		$	29.5		$	(175.7	)
Loss from discontinued operations	(0.3		)	(0.7		)	(5.6		)
Net income (loss)	$	177.1		$	28.8		$	(181.3	)
Denominator:

Diluted shares outstanding	144.3			142.6			133.2
Basic earnings per share:
Income (loss) from continuing operations	$	1.27		$	0.22		$	(1.32	)
Loss from discontinued operations	—			(0.01		)	(0.04		)
Net income (loss) per share	$	1.27		$	0.21		$	(1.36	)
Diluted earnings per share:
Income (loss) from continuing operations	$	1.23		$	0.20		$	(1.32	)
Loss from discontinued operations	—			—			(0.04		)
Net income (loss) per share	$	1.23		$	0.20		$	(1.36	)

Stock options, warrants and stock settled stock appreciation rights (SSARs) related to approximately 2.3 million and 5.3 million common shares were considered not in-the-money for purposes of LP's earnings per share calculation for the years ended December 31, 2013 and 2012. Stock options, warrants and stock settled stock appreciation rights (SSARs) related to approximately 7.1 million common shares for the year ended December 31, 2011 were considered anti-dilutive for purposes of LP’s earnings per share calculation due to LP’s loss position in continuing operations.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

Cash and cash equivalents consist of money market investments with an initial maturity of three months or less. These investments are stated at cost, which approximates market value.

Investment, Policy [Policy Text Block]

Investments

LP’s long-term investments are classified as available-for-sale and are reported at estimated fair value. LP may invest in securities including U.S. treasury notes, bank obligations, corporate obligations, auction rate securities and commercial paper. Under LP’s investment criteria at purchase, bank and corporate obligations carry a rating of at least A-1 and commercial paper must have the highest rating obtainable from one or more rating agencies. Unrealized gains and losses, net of tax, on these investments are reported as a separate component of “Accumulated comprehensive loss” in Stockholders’ Equity until realized. Impairment losses are charged to income for other-than-temporary declines in fair value. Realized gains and losses (including impairments) are recorded in “Investment income” in the Consolidated Statements of Income. For purposes of computing realized gains and losses, cost is identified on a specific identification basis. See Note 2 for further discussion.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value of Financial Instruments

LP has, where appropriate, estimated the fair value of financial instruments. These fair value amounts may be significantly affected by the assumptions used, including the discount rate and estimates of cash flows. Accordingly, the estimates presented are not necessarily indicative of the amounts that could be realized in a current market exchange.

Inventory, Policy [Policy Text Block]

Inventory

Inventories are valued at the lower of cost or market. Inventory costs include materials, labor and operating overhead. The LIFO (last-in, first-out) method is used for a minor portion of the Company’s log inventories with the remaining inventories valued at FIFO (first-in, first-out) or average cost. See Note 5 for further discussion.

Timber and timberlands [Policy Text Block]

Timber and Timberlands

Timber and timberlands is comprised of timber deeds and allocations of purchase price to Canadian timber harvesting licenses. Timber deeds are transactions in which LP purchases timber, but not the underlying land. The cost of timber deeds are capitalized in timber and timberlands and charged to cost of timber harvested as the volume is removed. Timber that has been severed but has not yet been delivered to a facility is included in timber and timberlands. The values associated with timber licenses were allocated in the purchase price allocations for Le Groupe Forex (Forex), Peace Valley OSB and the assets of Evans Forest Products. These licenses have a life of twenty to twenty-five years. These licenses are amortized on a straight-line basis over the life of the facilities. Cost of timber harvested also includes the amortization of the timber licenses. See Note 7 for further discussion.

Assets held for sale policy [Policy Text Block]

Assets Held for Sale

Over the last several years, LP has adopted and implemented plans to sell selected assets in order to improve its operating results. LP is required to classify assets held for sale which are not part of a discontinued business separately on the face of the financial statements outside of “Property, plant and equipment”. As of December 31, 2013 and 2012, LP included two OSB mills and various non-operating sites in its held for sale category. See Note 3 for discussion of impairments recorded on these assets to reduce carrying value to estimated sales prices less estimated selling costs. During 2013, assets held for sale of $14.9 million were reclassified to assets held and used, due to a change in the plan of sale. The 2012 disclosure below was updated to reflect this change. The current book values of assets held for sale by category is as follows:

Dollar amounts in millions	December 31,
	2013			2012
Property, plant and equipment, at cost:
Land, land improvements and logging roads, net of road amortization	$	6.9		$	7.1
Buildings	6.2			7.8
Machinery and equipment	99.1			99.7
	112.2			114.6
Accumulated depreciation	(95.9		)	(97.0		)
Net property, plant and equipment	$	16.3		$	17.6

LP believes that the net realizable sales value of the aforementioned assets exceeds their carrying values.

Property, Plant and Equipment, Policy [Policy Text Block]

Property, Plant and Equipment

Property, plant and equipment, including capitalized interest, are recorded at cost. Depreciation for financial statement purposes is provided principally using the units of production method for machinery and equipment which amortizes the cost of equipment over the estimated units that will be produced during its useful life. Provisions for depreciation of buildings, land improvements and the remaining machinery and equipment have been computed using straight-line rates based on the estimated service lives. The effective straight-line lives for the principal classes of property range from three to twenty years.

Logging road construction costs are capitalized and included in land and land improvements. These costs are amortized as the timber volume adjacent to the road system is harvested.

LP capitalizes interest on borrowed funds during construction periods. Capitalized interest is charged to machinery and equipment accounts and amortized over the lives of the related assets. Capitalized interest totaled $1.6 million in 2013 and $0.2 million in 2012.

Asset Impairment, Policy [Policy Text Block]

Potential Impairments

Long-lived assets to be held and used by LP (primarily property, plant and equipment and timber and timberlands) are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. When impairment is indicated, the book values of the assets are written down to their estimated fair value as calculated by the expected discounted cash flow or estimated net sales price. See Note 3 for impairment charges recorded in the periods presented. See Note 17 for a discussion of charges in 2013, 2012 and 2011 related to impairments of property, plant and equipment. Long-lived assets that are held for sale are written down to the estimated sales proceeds less cost to sell unless the estimated net proceeds exceed the carrying value.

LP continues to review certain operations and investments for potential impairments. LP’s management currently believes it has adequate support for the carrying value of each of these operations and investments based upon the anticipated cash flows that result from estimates of future demand, pricing and production costs assuming certain levels of planned capital expenditures. As of December 31, 2013, the fair values of LP's facilities were substantially in excess of their carrying value, which supported the conclusion that no impairment is necessary for those facilities. However, if demand and pricing for the relevant products continues at levels significantly below cycle average demand and pricing, or should LP decide to invest capital in alternative projects, it is possible that impairment charges will be required.

Income Taxes, Policy [Policy Text Block]

Income Taxes

LP accounts for income taxes under an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in LP’s financial statements or tax returns. In estimating future tax consequences, LP generally considers all expected future events other than the enactment of changes in tax laws or rates and future income. The effect on deferred tax assets and liabilities of a change in tax rates will be recognized as income or expense in the period that includes the enactment date. Additionally, deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion of the deferred tax assets will not be realized.

LP recognizes liabilities for uncertain tax positions through a two step process. The first step is to the evaluate the tax position for recognition by determining if the weight of the available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation process, if any. The second step requires LP to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as LP must determine the probability for various outcomes. LP evaluates these uncertain tax provisions when new information becomes available. These revaluations are based upon factors including, but not limited to, changes in circumstances, changes in tax law, successful settlement of issues under audit and new audit activity. Such a change in recognition or measurement could result in the recognition of a tax benefit or an increase to the related provision.

LP classifies interest related to income taxes liabilities or uncertain tax positions as interest expense or interest income and, if applicable, penalties are recognized as a component of income tax expense.

See Note 10 for further discussion of deferred taxes.

Stock-based Compensation Policy [Policy Text Block]

Stock-Based Compensation

LP recognizes the cost of employee services received in exchange for awards of equity instruments, such as stock options, performance shares, restricted stock or restricted stock units and stock settled stock appreciation rights (SSAR), based upon the fair value of those awards at the date of grant over the requisite service period. LP generally uses the Black-Scholes-Merton (Black-Scholes) option pricing model to determine the fair value of the stock option and SSAR awards. Stock-based compensation plans, related expenses and assumptions used in the Black-Scholes option pricing model are more fully described in Note 14. The fair market value of performance share awards are determined based on the fair value as of the date of grant times the number of shares adjusted for the weighted probability of the attainment of the relevant performance goals.

Derivative Financial Instruments [Policy Text Block]

Derivative Financial Instruments

To reduce foreign currency exchange and interest rate risks, LP occasionally utilizes derivative financial instruments, which include forward exchange, options and futures contracts. For the years ended December 31, 2013, 2012 and 2011, LP did not enter into any material derivative financial contracts.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Currency Translation

The functional currency for the Company’s Canadian subsidiaries is the U.S. dollar; however the books and records for these subsidiaries are maintained in the Canadian dollar. The financial statements of these foreign subsidiaries are remeasured into U.S. dollars using the historical exchange rate for property, plant and equipment, timber and timberlands, goodwill, and certain other non-monetary assets and related depreciation and amortization on these assets and liabilities. LP uses the exchange rate at the balance sheet date for the remaining assets and liabilities, including deferred taxes. A weighted-average exchange rate is used for each period for revenues and expenses. These transaction gains or losses are recorded in “Other non-operating income (expense)” on the Consolidated Statements of Income.

The functional currencies of LP’s Chilean, Brazilian and Peruvian subsidiaries are the Chilean peso, Brazilian real and Peruvian nuevo sol and their books and records are maintained in the local currency. Translation adjustments, which are based upon the exchange rate at the balance sheet date for assets and liabilities and the weighted-average rate for the income statement, are recorded in “Accumulated comprehensive loss” in Stockholders’ equity.

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]

Goodwill

Goodwill is tested for impairment on an annual basis, and when indicators of impairment are determined to exist. Impairment is evaluated by applying a fair value based test. Impairment losses would be recognized whenever the implied fair value of goodwill is less than its carrying value.

Intangible Assets, Policy [Policy Text Block]

Intangible Assets

Intangible assets with finite useful lives are amortized generally on a straight-line basis over the periods benefited. Impairment of the intangible asset is evaluated when factors indicate impairment may exist.

Restricted Cash, Policy [Policy Text Block]

Restricted Cash

In accordance with LP’s credit facilities, discussed at Note 12, LP has established restricted cash accounts. As of December 31, 2013, a portion of the restricted cash secures outstanding letters of credit under LP’s U.S. and Canadian credit facilities.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition

Revenue is recognized when customers receive products and title has passed. The following criteria are used to determine that title has passed: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the price to the buyer is fixed or determinable; and (4) the collection is reasonably assured.

During 2013, 2012 and 2011, LP's top ten customers accounted for approximately 44%, 46% and 48% of its sales. During 2012, Home Depot, Inc. accounted for more than 10% of its sales with no customers exceeding 10% in 2013 or 2011.

Pricing and Sales Incentives [Policy Text Block]

Pricing and Sales Incentives

LP records estimated reductions to revenue for customer programs and incentive offerings, including pricing arrangements, promotions and other volume-based incentives, at the date revenue is recognized. Some of these incentives are negotiated up front with the customer and are redeemable only if the customer achieves a specified cumulative level of sales (measured in dollars or units) or sales increase. Under these incentive programs, at the time of sale, LP estimates the anticipated rebate to be paid based upon forecasted sales levels. These forecasts are updated on a regular basis. If the forecasted sales for a customer change significantly, the accrual for rebates is adjusted to reflect the revised estimate.

Asset Retirement Obligations, Policy [Policy Text Block]

Asset Retirement Obligations

LP records the fair value of the legal obligations and the conditional obligations to retire and remove long-lived assets in the period which the obligation is incurred. These obligations primarily consist of monitoring costs on closed landfills, timber reforestation obligations associated with LP’s timber licenses in Canada and certain site restoration costs. When the related liability is initially recorded, LP capitalizes the cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its settlement value and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, LP recognizes a gain or loss for any difference between the settlement amount and the liability recorded. See Note 15 for further discussion.

Deferred Debt Costs, Policy [Policy Text Block]

Deferred Debt Costs

Deferred debt costs are amortized over the life of the related debt using a straight line basis which approximates the effective interest method. If the debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired to other non-operating income (expense). During 2013, $1.4 million and during 2012, $4.5 million of deferred debt costs were written off in association with the early debt extinguishment. LP amortized deferred debt costs of $1.4 million, $1.5 million and $2.6 million for the years ended December 31, 2013, 2012 and 2011. See Note 11 for further discussion.

Other operating charges and credits policy [Policy Text Block]

Other Operating Credits and Charges, Net

LP classifies significant amounts that management considers unrelated to ongoing core operating activities as “Other operating credits and charges, net” in the Consolidated Statements of Income. Such items include, but are not limited to, amounts related to restructuring charges (including severance charges), charges to establish and maintain litigation or environmental reserves, product reserves, prior year inventory profit adjustments, retirement charges and gains or losses from settlements with governmental or other organizations. Due to the nature of these items, amounts in the income statement can fluctuate from year to year. The determination of which items are considered significant and unrelated to core operations is based upon management’s judgment. See Note 16 for a discussion of specific amounts in 2013, 2012 and 2011.

Retirement Benefits Policy [Policy Text Block]

Retirement Benefits

LP is required to use actuarial methods and assumptions in the valuation of defined benefit obligations and the determination of expense. Difference between actual and expected results or changes in the values of the obligations and plan assets are not recognized in earnings as they occur but, rather, systematically and gradually over subsequent periods. See Note 13 for further information.

Comprehensive Income, Policy [Policy Text Block]

Comprehensive Income

Comprehensive income consists of net income (loss) and other gains and losses affecting shareholders’ equity that are excluded from net income (loss), including foreign currency translation adjustments, prior service costs and credits, transition assets or obligations associated with pension or other post retirement benefits that have not been recognized as components of net periodic benefit costs, net unrealized gains or losses on securities, and unrealized gains and losses on financial instruments qualifying for cash flow hedge accounting, and is presented in the accompanying Consolidated Statements of Comprehensive Income. See Note 23 for further discussion.

New Accounting Pronouncements, Policy [Policy Text Block]

Present and Prospective Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02 "Reporting of Amounts Reclassified Out of Accumulated Comprehensive Income." The amendment does not change the current requirement for reporting net income or other comprehensive income in financial statements; however, the amendment requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The new disclosure requirements were effective for all periods beginning after December 15, 2012. The adoption of the amendments impacts presentation only and did not have an effect on LP’s financial condition, results of operations or cash flows. See Note 23 for further discussion.

Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

STOCKHOLDERS' EQUITY

Preferred Stock

The Company is authorized to issue up to 15,000,000 shares of preferred stock at $1.00 par value. At December 31, 2013, no shares of preferred stock have been issued; however, 2,000,000 shares of Series A Junior Participating Preferred Stock have been reserved for issuance in connection with the Company’s Shareholder Rights Plan. Additional series of preferred stock may be designated and the related rights and preferences fixed by action of the Board of Directors.

Shareholder Rights Plan

In May 2008, the Board of Directors approved a shareholder rights plan and declared a dividend of one preferred share purchase right for each outstanding share of common stock. Each right represents the right to purchase one-hundredth of a share of Preferred Stock, at an exercise price of $100.00, subject to adjustment. The rights are only exercisable ten days after a person or group acquires, or commences a tender or exchange offer to acquire, beneficial ownership of 15% or more of the Company’s outstanding common stock.

Subject to the terms of the shareholder rights plan and the discretion of the Board of Directors, each right would entitle the holder to purchase a number of additional shares of common stock of LP having a total market value of twice the exercise price of each right. The rights expire in June 2018, but can be redeemed by action of the Board of Directors prior to that time at $0.01 per right.

Warrants

During 2009, LP issued warrants to purchase 18,395,963 shares of LP common stock at an exercise price of $1.39 per share subject to mandatory cashless exercise provisions. During the years ended December 31, 2013 and December 31, 2012, warrant exercises resulted in the issuances of 1,621,362 and 605,798 shares. At December 31, 2013, the remaining outstanding warrants were exercisable to purchase approximately 1,462,119 shares. The warrants (at date of grant) were valued based upon Black-Scholes option pricing model using expected stock price volatility of 53%; no expected dividends; risk-free interest rate of 2.6%; and an expected life of 8 years, which resulted in a fair value per share of $0.72.

Common Stock Plans

At December 31, 2013, LP had stock-based employee compensation plans as described below. The total compensation expense related to all of LP’s stock-based compensation plans was $8.8 million for the year ended December 31, 2013; $8.4 million for the year ended December 31, 2012 and $7.8 million for the year ended December 31, 2011.

LP recognizes these compensation costs net of an estimated forfeiture rate and recognizes the compensation costs for only those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the vesting term of three years. LP estimated the forfeiture rate for 2013, 2012 and 2011 based on its historical experience during the preceding three years.

Stock Compensation Plans

LP grants options to purchase LP common stock and stock settled appreciation rights (SSARs) to key employees and directors. On exercise or issuance, LP generally issues these shares from treasury. The options and SSARs are granted at market price at the date of grant. For employees, options and SSARs become exercisable over three years and expire ten years after the date of grant. For directors, these options become exercisable in 10% increments every three months, starting three months after the date of grant, and expire ten years after the date of grant. At December 31, 2013, 5.6 million shares were available under the current stock award plans for stock-based awards. The following table sets out the weighted average assumptions used to estimate the fair value of the options and SSARs granted using the Black-Scholes option-pricing model:

	2013			2012			2011
Expected stock price volatility	69		%	64		%	64		%
Expected dividend yield	—		%	—		%	—		%
Risk-free interest rate	0.9		%	0.7		%	2.1		%
Expected life of options (in years)	5.0 years			5.1 years			5.2 years
Weighted average fair value of options and SSARs granted	$	11.68		$	4.75		$	5.59

Expected Stock Price Volatility: The fair values of stock-based payments were valued using the Black-Scholes valuation method with a volatility factor based on LP’s historical stock prices.

Expected Dividend Yield: The Black-Scholes valuation model calls for a single expected dividend yield as an input. This is determined based upon current annual dividend as of the date of grant compared to the grant price.

Risk-Free Interest Rate: LP bases the risk-free interest rate used in the Black-Scholes valuation method on U.S. Treasury issues with an equivalent term. Where the expected term of LP’s stock-based awards do not correspond with the terms for which interest rates are quoted, LP performed a straight-line interpolation to determine the rate from the available maturities.

Expected Life of Options: Expected life represents the period that LP’s stock-based awards are expected to be outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior as influenced by changes to the terms of its stock-based awards.

Estimated Pre-vesting Forfeitures: When estimating forfeitures, LP considers voluntary termination behavior as well as workforce reduction programs.

The following table summarizes stock options and SSARs outstanding as of December 31, 2013 as well as activity during the three year period then ended.

Share amounts in thousands	Options/ SSARs		Weighted Average Exercise Price		Weighted Average Contractual Term (in years)	Aggregate Intrinsic Value (in millions)

⁽¹⁾  Options or SSARS expected to vest based upon historical forfeiture rate

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between LP’s closing stock price on the last trading day of 2013 and the exercise price, multiplied by the number of in-the-money options and SSARs) that would have been received by the holders had all holders exercised their awards on December 31, 2013. This amount changes based on the market value of LP’s stock as reported by the New York Stock Exchange.

As of December 31, 2013, there was $4.1 million of total unrecognized compensation costs related to stock options and SSARs. These costs are expected to be recognized over a weighted-average period of 1.2 years. LP recognized $3.4 million, $3.7 million and $3.9 million in compensation expense associated with these awards for the years ended December 31, 2013, 2012 and 2011.

Incentive Share Awards

LP has granted incentive share stock awards (restricted stock units) to certain key employees as allowed under the current stock award plans. The awards entitle the participant to receive a specified number of shares of LP common stock at no cost to the participant. Awards granted under this plan vest three years from the date of grant. The market value of these grants approximates the fair value. LP recorded compensation expense related to these awards in 2013, 2012 and 2011 of $2.7 million, $2.3 million and $2.3 million. As of December 31, 2013, there was $3.1 million of total unrecognized compensation cost related to unvested incentive share awards. This expense will be recognized over a weighted-average period of 0.9 years.

The following table summarizes incentive share awards outstanding as of December 31, 2013 as well as activity during the three year period then ended.

Restricted Stock

LP grants restricted stock to certain senior executive employees. The shares vest three years from the date of grant. During the vesting period, the participants have voting rights and receive dividends, but the shares may not be sold, assigned, transferred, pledged or otherwise encumbered. Additionally, granted but unvested shares are forfeited upon termination of employment. The fair value of the restricted shares on the date of the grant is amortized ratably over the vesting period which is generally three years. As of December 31, 2013, there was $2.4 million of total unrecognized compensation costs related to restricted stock. This expense will be recognized over the next year.

The following table summarizes restricted stock awards outstanding as of December 31, 2013 as well as activity during the three year period then ended.

LP recorded compensation expense related to these awards in 2013, 2012 and 2011 of $2.1 million, $1.8 million, and $1.5 million.

Performance Share Awards

In connection with Mr. Stevens' appointment to Chief Executive Officer on May 4, 2012, he was awarded 300,000 performance shares. This award was granted pursuant to the terms of LP's 1997 Incentive Stock Award Plan. If pre-determined market-based performance goals are met, shares of LP's stock will be issued to Mr. Stevens based upon a pre-determined vesting schedule based upon the required service periods. The fair market value of this award was determined based on the fair value as of the date of grant times the number of shares adjusted for the weighted probability of the attainment of certain performance goals. LP recorded compensation expense related to these awards of $0.3 million in 2013. As of December 31, 2013, there was $0.8 million of total unrecognized compensation expense related to this award. This expense will be recognized over the next 2.3 years.

Phantom Stock

During 2011 and 2012, LP made annual grants of phantom stock units to its directors. Subsequent to the approval of the 2013 Omnibus Plan, phantom stock units are no longer granted to directors. The awards are considered liability awards. The director does not receive rights of a shareholder, nor is any stock transfered. The units will be paid in cash at the end of the five year vesting period. The value of one unit is based on the market value of one share of common stock on the vesting date. The cost of the grants is recognized over the vesting period and is included in stock-based compensation expense. As of December 31, 2013, LP had phantom stock units covering 75,816 shares outstanding under this program. LP recorded compensation expense related to these awards of $0.3 million in 2013.

Noncontrolling Interest [Abstract]

Noncontrolling Interest

NON-CONTROLLING INTEREST

In May 2008, LP completed the initial phase of its purchase of a 75% ownership interest in Massisa OSB Industria e Comercio S.A., which operates OSB assets located in Ponta Grossa, Brazil. The purchase was made through LP Brasil Participacoes Ltda., a former limited liability company and indirect subsidiary of LP. The non controlling ownership was subject to a put and call option that became exercisable in 2011, was being accounted for as a redeemable non controlling interest and was accreted over the life of the put and call to the estimated price which was the greater of $18.5 million plus interest plus the greater of $2.0 million or 25% of related working capital or a multiple of earnings before interest and taxes (subject to certain adjustments). The purchase price in 2008 was approximately $56.5 million (including expenses). LP took over operations in November 2008.

In June 2011, LP purchased the remaining 25% ownership of LP Brazil from Massisa for a payment of $24.0 million. Subsequent to the purchase, LP incurred $10.0 million of long term export financing debt in connection with the purchase and used a portion of the proceeds to repay interim borrowing incurred to fund a portion of the purchase price.

Fair Value Disclosures [Abstract]

Fair Value Measurements

FAIR VALUE MEASUREMENTS

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. LP is required to classify these financial assets and liabilities into two groups: recurring—measured on a periodic basis and non-recurring—measured on an as needed basis.

There are three levels of inputs that may be used to measure fair value:

Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2 Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; or valuations based on models where the significant inputs are observable or can be corroborated by observable market data.

Level 3 Valuations based on models where significant inputs are not observable. Unobservable inputs are used when little or no market data is available and reflect the Company’s own assumptions about the assumptions market participants would use.

Assets and liabilities measured at fair value on a recurring basis as of December 31, 2013 and 2012 is summarized in the following tables.

Dollar amounts in millions	December 31, 2013		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Available for sale securities	$	3.7	$	—	$	—	$	3.7

Trading securities	1.7		1.7		—		—
Total	$	3.7	$	1.7	$	—	$	2.0

Due to the lack of observable market quotations on a portion of LP’s auction rate securities (ARS) portfolio, LP evaluates the structure of its ARS holdings and current market estimates of fair value, including fair value estimates from issuing banks that rely exclusively on Level 3 inputs. These inputs include those that are based on expected cash flow streams and collateral values, including assessments of counterparty credit quality, default risk underlying the security, discount rates and overall capital market liquidity. The valuation of LP’s ARS investment portfolio is subject to uncertainties that are difficult to predict. Factors that may impact LP’s valuation include changes to credit ratings of the securities as well as to the underlying assets supporting those securities, rates of default of the underlying assets, underlying collateral value, discount rates, counterparty risk and ongoing strength and quality of market credit and liquidity.

Trading securities consist of rabbi trust financial assets which are recorded in other assets in LP’s consolidated balance sheets. The rabbi trust holds assets attributable to the elections of certain management employees to defer the receipt of a portion of their compensation. The assets of the rabbi trust are invested in mutual funds and are reported at fair value based on active market quotations, which represent Level 1 inputs.

The following table summarizes changes in assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the twelve months ended December 31, 2013 and 2012.

Carrying amounts reported on the balance sheet for cash, cash equivalents, receivables and accounts payable approximate fair value due to the short-term maturity of these instruments.

LP reviews the carrying values of long-lived assets to be held and used for impairment wherever events or changes in circumstances indicate possible impairment. An impairment loss is recognized when a long-lived asset's carrying value is not recoverable (given assumptions on housing starts and growth rates) and exceeds estimated fair value.

During the year ended 2013, LP recognized a gain of $20.5 million as a fair value adjustment to the contingent consideration payable in connection with a business combination (see Note 24 for further discussion). The fair value of the contingent consideration was reduced during the year due to the decline in projected OSB prices as compared to the initial fair value which was established at the date of the acquisition. This reduction resulted in lowering the estimated payment obligation. The fair value adjustment is recorded in Other Operating Credits and Charges, Net (see Note 16 for further discussion). This fair value was determined based upon the income approach using significant non-observable inputs such as projected OSB pricing taking into consideration volatility of such projections.

During the year ended 2012, LP recognized an impairment charge of $4.4 million on an OSB mill in Quebec, Canada, held for sale based upon a change in the plan for its sale and to reduce its carrying value to estimated selling price less selling costs of $15.0 million. The valuation of the affected assets was determined using level two inputs under the market approach. During 2013, this mill was reclassified to held and used.

During the year ended December 31, 2011, LP determined that an impairment review was required of its LSL facility located in Houlton, Maine due to continued operating losses which were driven by the significant reductions in current and forecasted housing starts. As a result of this review, LP recognized a pre-tax, non-cash impairment charge of $62.0 million. The estimated fair value of long-lived assets was calculated based on the income approach using the discounted probability of weighted cash flows taking into account current expectations for asset utilization, housing starts and the remaining useful life of related assets. In addition, liquidation values were considered where appropriate, as well as indicated values from divestiture activities. These assets are included in LP's property, plant and equipment (long-lived assets) which are held and used.

During the year ended December 31, 2011, LP recorded an impairment charge of $6.9 million on various assets held for sale to reduce their carrying value to the estimated sales price less estimated selling costs. The valuation of these assets was determined based upon level two inputs under the market approach. Also, LP recorded an impairment charge of $4.9 million on assets no longer used.

COMMITMENTS AND CONTINGENT LIABILITIES

LP is primarily self-insured for workers’ compensation and employee health care liability costs. Self-insurance liabilities for workers’ compensation are determined based upon a valuation performed by an actuarial firm. The estimate of future workers’ compensation liabilities incorporates loss development and an estimate associated with incurred but not yet reported claims. These claims are discounted. Self-insurance liabilities for employee health costs are determined actuarially based upon claims filed and estimated claims incurred but not yet reported. These claims are not discounted.

The Company and its subsidiaries lease certain office, manufacturing, warehousing and other plant sites and equipment. The leases generally provide for the lessee to pay taxes, maintenance, insurance and certain other operating costs of the leased properties.

At December 31, 2013, future minimum annual rent commitments are as follows:

Retirement Plans and Post Retirement Benefits

Compensation and Retirement Disclosure [Abstract]

Retirement Plans and Postretirement Benefits

RETIREMENT PLANS AND POSTRETIREMENT BENEFITS

LP sponsors various defined benefit and defined contribution retirement plans that provide retirement benefits to substantially all of its employees. Most regularly scheduled employees are eligible to participate in these plans except those covered by a collective bargaining agreement, unless the collective bargaining agreement specifically allows for participation in LP’s plans. LP contributes to a multiemployer plan for certain employees covered by collective bargaining agreements. LP also provides other post retirement benefits consisting primarily of healthcare benefits to certain retirees who meet age and service requirements.

Defined Benefit Plans

Pension benefits are earned generally based upon years of service and compensation during active employment. Contributions to the qualified defined benefit pension plans are based on actuarial calculations of amounts to cover current service costs and amortization of prior service costs over periods ranging up to 20 years. LP contributes additional funds as necessary to maintain desired funding levels.

Benefit accruals under our most significant plans, which account for approximately 80% of the assets and 82% of the benefit obligations in the tables below, had been credited at the rate of 4% of eligible compensation with an interest credit based upon the 30-year U.S. Treasury rate. The Company discontinued providing contribution credits effective January 1, 2010 to these plans. The remaining defined benefit pension plans (primarily in Canada) use a variety of benefit formulas.

LP also maintains a Supplemental Executive Retirement Plan (SERP), an unfunded, non-qualified defined benefit plan intended to provide supplemental retirement benefits to key executives. Benefits are generally based on compensation in the years immediately preceding normal retirement. LP has established a grantor trust that provides funds for the benefits payable under the SERP. The assets of the grantor trust are invested in corporate-owned life insurance policies. At December 31, 2013 and 2012, the trust assets were valued at $9.7 million and $8.8 million and are included in “Other assets” on the Consolidated Balance Sheets. LP did not contribute to this trust in 2013 or 2012. During the year ended December 31, 2012, LP paid its retiring CEO his accumulated SERP liability of $10.4 million through the use of the assets included in the grantor trust. In connection with this distribution, LP recorded a plan settlement charge of $2.2 million.

The components of LP’s net periodic pension costs and the assumptions related to those costs consisted of the following:

	Year ended December 31,
Dollar amounts in millions	2013			2012			2011
Service cost	$	3.4		$	3.7		$	2.9

Foreign exchange rate changes	0.2			—			(0.1		)
Total recognized in OCI	$	(43.3	)	$	2.2		$	38.2

LP calculates the net periodic pension cost for a given fiscal year based upon assumptions developed at the end of the previous fiscal year. As of January 1, 2010 LP froze future contribution credits a to its qualified U.S. defined benefit pension plans. LP recognized settlement charges of $2.2 million during 2012, related to the LP SERP pension plan associated with the retirement of LP's previous CEO.

The expected long-term rate of return on plan assets reflects the weighted-average expected long-term rates of return for the broad categories of investments currently held in the plans (adjusted for expected changes), based on historical rates of return for each broad category, as well as factors that may constrain or enhance returns in the broad categories in the future. The expected long-term rate of return on plan assets is adjusted when there are fundamental changes in expected returns in one or more broad asset categories and when the weighted-average mix of assets in the plans changes significantly.

The projected benefit obligation is the actuarial present value of benefits attributable to employee service rendered to date, including the effects of estimated salary increases. The benefit plan obligation, funded status and the assumptions related to the obligations as of the measurement date for each year presented as of December 31 follow:

The total accumulated benefit obligation for all pension plans as of December 31, 2013 and 2012 was $317.7 million and $346.0 million.

The accumulated benefit obligation and fair value of plan assets for pension plans with accumulated benefit obligations in excess of plan assets were $304.7 million and $256.7 million at December 31, 2013 and $331.7 million and $244.6 million at December 31, 2012. The projected benefit obligations and fair value of plan assets of plans with projected benefit obligations in excess of plan assets were $309.0 million and $256.7 million at December 31, 2013 and $337.7 million and $244.6 million at December 31, 2012.

The amounts of accumulated other comprehensive income that is expected to be amortized as expense during 2014 is:

These estimated benefit payments are based upon assumptions about future events. Actual benefit payments may vary significantly from these estimates.

Asset allocation targets are established based upon the long-term returns and volatility characteristics of the investment classes and recognize the benefits of diversification and the profits of the plans’ liabilities. The actual and target allocations at the measurement dates are as follows:

	Target Allocation 2013		Actual Allocation
			2013		2012
Asset category
Equity securities	49.1	%	46.4	%	36.4	%
Debt securities	24.9		36.8		37.8
Real estate	8.0		6.2		5.8
Other, including cash and cash equivalents	18.0		10.6		20.0
Total	100.0	%	100.0	%	100.0	%

LP’s investment policies for the defined benefit pension plans provide target asset allocations by broad categories of investment and ranges of acceptable allocations. These policies are set by an administrative committee with the goal of maximizing long-term investment returns within acceptable levels of volatility and risk. LP’s U.S. plans include real estate, hedge funds and real return investment strategies to increase returns and reduce volatility. LP’s plans do not currently invest directly in derivative securities, although such investments may be considered in the future to increase returns and/or reduce volatility. To the extent the expected return on plan assets varies from the actual return, an actuarial gain or loss results.

The fair value of LP’s pension plan assets at December 31, 2013 and December 31, 2012, fair value asset categories and the level of inputs as defined in Note 3 are as follows:

Level 1 investments are valued based on active market quotations.

Level 2 investments are valued based on the unit prices quoted by the funds, representing the fair value of underlying investments.

Due to the lack of observable market quotations on real estate and multi-strategy funds, LP evaluates their structure and current market estimates of fair value, including fair value estimates from the funds that rely exclusively on Level 3 inputs. These inputs include those that are based on expected cash flow streams and property values, including assessments of overall market liquidity. The valuations are subject to uncertainties that are difficult to predict.

The following table summarizes assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the period.

Defined Contribution Plans

LP also sponsors defined contribution plans in the U.S. and Canada. In the U.S., these plans are primarily 401(k) plans for hourly and salaried employees that allow for pre-tax employee deferrals and a company match of up to 3.5% of an employee’s eligible wages (subject to certain limits). Under the profit sharing feature of these plans, LP may elect to contribute a discretionary amount as a percentage of eligible wages. Included in the assets of the 401(k) and profit sharing plans are 2.6 million shares of LP common stock that represented approximately 15.4% of the total market value of plan assets at December 31, 2013.

In Canada, LP sponsors both defined contribution plans and Registered Retirement Savings Plans for hourly and salaried employees that allow for pre-tax employee deferrals. LP provides a base contribution of 2.5% of eligible earnings and matches 50% of an employee’s deferrals up to a maximum of 3% of each employee’s eligible earnings (subject to certain limits).

Expenses related to defined contribution plans and the multiemployer plan in 2013, 2012 and 2011 were $8.3 million, $5.2 million and $5.5 million.

Other Benefit Plans

LP has several plans that provide postretirement benefits other than pensions, primarily for salaried employees in the U.S. and certain groups of Canadian employees. The funded status at December 31, 2013 and 2012 was $8.2 million and $9.7 million. Net expense related to these plans was not significant in 2013 or 2012.

Effective August 16, 2004, LP adopted the Louisiana-Pacific Corporation 2004 Executive Deferred Compensation Plan (the Plan). Pursuant to the Plan, certain management employees are eligible to defer up to 90% of their regular salary and annual cash incentives that exceed the limitation as set forth by the Internal Revenue Service. Each plan participant is fully vested in all employee deferred compensation and earnings credited associated with employee contributions. Employer contributions and associated earnings vest over periods not exceeding five years. The liability under this plan amounted to $1.9 million and $1.5 million at December 31, 2013 and December 31, 2012 and is included in “Other long-term liabilities” on LP’s Consolidated Balance Sheets.
