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 limited sales to Asia, Australia and Europe. See Note 23 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. 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 income of unconsolidated affiliates” on the Consolidated Statements of Income. See Note 8 for further discussion of these investments and advances. LP has a variable interest in its Abitibi-LP equity method investee but is not considered to be the primary beneficiary. Cash and Cash Equivalents Cash and cash equivalents includes cash on hand and short-term investments of 3 months or less when purchased. 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. Inventory consists of the following: December 31, Dollar amounts in millions 2016 2015 Logs $ 54.6 $ 58.6 Other raw materials 23.0 21.6 Semi finished inventory 16.8 18.5 Finished products 140.2 123.3 Total $ 234.6 $ 222.0 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, 2016 and 2015 , LP included various non-operating sites in its held for sale category. The current book values of assets held for sale by category is as follows: Dollar amounts in millions December 31, 2016 2015 Property, plant and equipment, at cost: Land, land improvements and logging roads, net of road amortization $ 1.3 $ 1.8 Buildings 0.3 0.5 Machinery and equipment 6.6 6.7 Net property, plant and equipment $ 8.2 $ 9.0 LP believes that the net realizable sales value of the aforementioned assets exceeds their carrying values. 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. 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 $1.9 million in 2016 and 2015 . Plant, property and equipment, net consists of the following: Dollar amounts in millions December 31, 2016 2015 Property, plant and equipment, at cost: Land, land improvements and logging roads, net of road amortization $ 151.5 $ 137.0 Buildings 328.8 324.6 Machinery and equipment 1,881.8 1,897.4 Construction in progress 48.7 33.5 2,410.8 2,392.5 Accumulated depreciation (1,527.6 ) (1,530.1 ) Property, plant and equipment, net $ 883.2 $ 862.4 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 17 for a discussion of charges in 2016 , 2015 and 2014 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, 2016 , the fair values of LP's facilities were 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, or should changes occur related to LP's wood supply for these locations, it is possible that impairment charges will be required. Goodwill and Intangible assets 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 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 LP's restricted cash accounts generally secure outstanding letters of credit. 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. 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 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 income taxes. Asset Retirement Obligations LP records the fair value of the legal and 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 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. Stock-Based Compensation LP recognizes the cost of employee services received in exchange for awards of equity instruments, such as performance shares, restricted stock or restricted stock units and stock-settled stock appreciation rights (SSARs), based upon the fair value of those awards at the date of grant over the requisite service period. See Note 14 for further discussion. 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 (related depreciation and amortization on both property, plant and equipment and timber and timberlands), goodwill, and certain other non-monetary assets. 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 and Brazilian subsidiaries are the Chilean peso and Brazilian real 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 income (loss)” in Stockholders’ equity. Revenue Recognition Revenue is recognized when 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 2016 , 2015 and 2014 , LP's top ten customers accounted for approximately 41% , 45% and 41% of its sales. No customers exceeded 10% of LP's sales in 2016, 2015 or 2014. 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. 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 2016 , 2015 and 2014 . 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, costs associated with pension or other post retirement benefits that have not been recognized as components of net periodic benefit costs, and net unrealized gains or losses on securities and is presented in the accompanying Consolidated Statements of Comprehensive Income. See Note 22 for further discussion. Present and Prospective Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, "Revenue from Contracts with Customers (Topic 606)", which supersedes the revenue recognition requirements in Accounting Standards Codification (ASC) 605, Revenue Recognition. The new revenue recognition standard requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective on January 1, 2018. LP has elected to adopt the revenue recognition standard in the first quarter of 2018 with a cumulative adjustment to retained earnings. Based upon current interpretations, LP does not anticipate the adoption of this standard to have a material impact on LP’s financial statements. In July 2015, the FASB issued ASU 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory" which requires entities to measure most inventory "at the lower of cost and net realizable value," thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost of market. LP currently values all inventory at the lower of cost of market. The ASU will not apply to inventories that are measured by using the last -in, first out (LIFO), which is the method that LP currently uses for a minor portion of its log inventories. The remaining inventories are valued using first-in, first-out or average cost. This ASU is effective prospectively for annual periods beginning after December 15, 2016 and interim periods therein. The adoption of this standard is not expected to have a material impact on LP's financial condition, results of operations or cash flow. In March 2016, the FASB issued ASU No. 2016-09, "Improvements to Employee Share-based Payment Accounting" which simplifies several aspects of the accounting for employee share-based payment transactions and addresses the presentation of excess tax benefits and employee taxes paid on the statement of cash flows. LP is now required to present excess tax benefits as an operating activity (combined with other income tax cash flows) on the statement of cash flows rather than as a financing activity, and LP has adopted this change prospectively. ASU 2016-09 also requires the presentation of employee taxes as a financing activity on the statement of cash flows, which is where LP has previously classified this item. LP adopted this standard using the modified retrospective approach as of January 1, 2016 and recorded a cumulative-effect adjustment of $16.3 million to increase retained earnings and increase long-term deferred tax asset. In March 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)", which supersedes the lease accounting requirements in ASC Topic 840, Leases. The new standard requires entities to recognize, separately from each other, an asset for its right to use (ROU) the underlying asset equal to the liability for its finance and operating lease obligations. Further, the entity is required to present separately the current and non-current portion of the ROU asset and corresponding lease liability. The new standard is effective on January 1, 2019. LP is currently evaluating the effect that adopting this new accounting guidance will have on its consolidated results of operations and financial position. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classifications of Certain Cash Receipts and Cash Payments." The standard provides guidance for eight changes with respect to how cash receipts and cash payments are classified in the statement of cash flows, with the objective of reducing diversity in practice. The new standard is effective January 1, 2018, with early adoption permitted. LP does not expect the adoption of this new standard to have a material impact on its consolidated results of operations and financial position. In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory." The standard provides guidance that entities recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Consequently, the amendments eliminate the exception for an intra-entity transfer of an asset other than inventory. The new standard is effective for annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual periods beginning after December 15, 2019. Early adoption is permitted for all entities as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance. LP does not expect the adoption of this new standard to have a material impact on its consolidated results of operations and financial position. In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash." This standard provides guidance that requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The new standard is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. LP does not expect the adoption of this new standard to have a material impact on its consolidated results of operations and financial position.

Investments [Abstract]
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, 2016 and December 31, 2015 : Dollar amounts in millions Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value December 31, 2016 $ 0.4 $ 4.4 $ — $ 4.8 December 31, 2015 $ 0.4 $ 5.4 $ — $ 5.8 As of December 31, 2016 , LP had $4.8 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 and other securities. The contractual maturities of these debt securities classified as available for sale at December 31, 2016 exceed one year. There were no purchases of short-term and long-term investments for the years ended December 31, 2016 and 2015 . During 2016 and 2015 , LP did not own any short-term investments.

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, 2016 and 2015 is summarized in the following tables. Dollar amounts in millions December 31, 2016 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 $ 4.8 $ — $ — $ 4.8 Trading securities 2.6 2.6 — — Dollar amounts in millions December 31, 2015 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 $ 5.8 $ — $ — $ 5.8 Trading securities 2.3 2.3 — — Due to the lack of observable market quotations on a portion of LP’s 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, 2016 and 2015 . Dollar amounts in millions Available for sale securities Contingent consideration Balance at December 31, 2014 $ 4.6 $ 0.2 Adjustment to contingent consideration fair value — (0.2 ) Total realized/unrealized gains (losses) included in other comprehensive income 1.2 — Balance at December 31, 2015 $ 5.8 $ — Total realized/unrealized gains (losses) included in other comprehensive income (1.0 ) — Balance at December 31, 2016 $ 4.8 $ — Carrying amounts reported on the balance sheet for cash and cash equivalents, receivables and accounts payable approximate fair value due to the short-term maturity of these instruments. See discussion on fair market values on Notes Receivable from Asset Sales at Note 6 and Long-term Debt at Note 12. 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 2016, LP entered into a non-monetary transaction to exchange its idled OSB mill for another idled mill. This transaction was recorded at the fair market value of both facilities based upon external appraisals. This transaction resulted in LP recording a gain of $10.6 million equal to the excess fair value over the net book value of the facility being exchanged.

Antidilutive Securities Excluded from Computation of Earnings Per Share [Line Items]
Earnings Per Share [Text Block]	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 2016 2015 2014 Numerator: Net income (loss): Income (loss) from continuing operations $ 150.3 $ (86.0 ) $ (73.4 ) Loss from discontinued operations (0.5 ) (2.1 ) (2.0 ) Net income (loss) $ 149.8 $ (88.1 ) $ (75.4 ) Denominator: Denominator for basic earnings per share: Weighted average common shares outstanding 143.4 142.4 141.1 Effect of dilutive securities: Dilutive effect of employee stock plans 1.7 — — Dilutive effect of stock warrants 0.2 — — Dilutive potential common shares 1.9 — — Denominator for diluted earnings per share: Adjusted weighted average shares 145.3 142.4 141.1 Basic earnings per share: Income (loss) from continuing operations $ 1.05 $ (0.60 ) $ (0.52 ) Loss from discontinued operations (0.01 ) (0.02 ) (0.01 ) Net income (loss) per share $ 1.04 $ (0.62 ) $ (0.53 ) Diluted earnings per share: Income (loss) from continuing operations $ 1.03 $ (0.60 ) $ (0.52 ) Loss from discontinued operations — (0.02 ) (0.01 ) Net income (loss) per share $ 1.03 $ (0.62 ) $ (0.53 ) Stock options, warrants and SSARs related to approximately 2.6 million common shares were considered not in-the-money for purposes of LP's earnings per share calculation for the year ended December 31, 2016 .

Transactions with Affiliates	INVESTMENTS IN AND ADVANCES TO AFFILIATES At December 31, 2016, LP has an investment in a joint venture with Resolute Forest Products to operate jointly owned I-Joist facilities in Quebec (Abitibi-LP). Each partner owns 50% of the venture. LP sells products and raw materials and purchases products for resale from Abitibi-LP. 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, 2016 , 2015 and 2014 , LP sold $11.7 million , $9.3 million and $9.8 million of products to Abitibi-LP and purchased $53.1 million , $54.1 million and $55.4 million of I-joists from Abitibi-LP. Included in LP’s Consolidated Balance Sheets at December 31, 2016 and 2015 are $1.9 million and $0.4 million in accounts receivable and $ 0.1 million and $ 0.1 million in accounts payable associated with Abitibi-LP. For the year ended December 31, 2016 , LP received $6.7 million in dividends from Abitibi-LP. LP classified the receipt of these cash dividends as cash flows from operations. LP's cumulative equity in earnings from Abitibi-LP exceeds the cumulative distributions received; therefore, the dividends were deemed to be a return on LP's investment and not a return of LP's investment.

Included in the Consolidated Balance Sheet at December 31, 2016 and 2015 are income tax receivables of $1.7 million and $2.0 million and income taxes payable of $31.3 million and $0.0 million . 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 2016 2015 Property, plant and equipment $ 164.2 $ 165.2 Timber and timberlands 11.6 12.0 Inventories (6.9 ) (7.7 ) Accrued liabilities (83.9 ) (79.7 ) Benefit of capital loss and NOL carryovers (83.4 ) (137.3 ) Benefit of tax credit carryovers (3.7 ) (21.0 ) Installment sale gain deferral 8.0 128.5 Market value write down of ARS (8.8 ) (8.8 ) Other (11.6 ) (12.6 ) Valuation allowance 37.9 56.1 Net deferred tax liabilities $ 23.4 $ 94.7 Balance sheet classification Long-term deferred tax asset (4.3 ) (4.8 ) Long-term deferred tax liability 27.7 99.5 $ 23.4 $ 94.7 The benefit relating to capital loss, net operating loss (NOL) and credit carryovers included in the above table at December 31, 2016 consists of: Dollar amounts in millions Expiration Beginning in Benefit Amount Valuation Allowance State NOL carryovers 2017 22.8 (8.4 ) State capital loss carryover 2017 0.1 (0.1 ) State credit carryovers 2017 0.7 (0.5 ) Canadian NOL carryovers 2029 52.9 (12.5 ) Canadian capital loss carryovers Indefinitely 7.1 (7.1 ) Canadian credit carryovers 2017 3.0 (3.0 ) Brazilian NOL carryovers Indefinitely 0.5 (0.5 ) $ 87.1 $ (32.1 ) 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 carryforwards. LP believes that the valuation allowances provided are appropriate. If future years’ earnings differ from the estimates used to establish these valuation allowances or other objective positive or negative evidence arises, LP may be required to record an adjustment resulting in an impact on tax expense (benefit) for that period. At December 31, 2015 , 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 $16.9 million of deferred tax assets that arose directly from tax deductions related to amounts of equity compensation that are greater than the compensation recognized for financial reporting. As of January 1, 2016, LP adopted ASU No. 2016-09, "Improvements to Employee Share-based Payment Accounting" and the aforementioned amount was recorded to retained earnings as an adjustment to beginning balance based upon the adoption of the new standard. U.S. taxes have not been provided on approximately $75.9 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, 2016 2015 2014 U.S. federal tax rate 35 % (35 )% (35 )% State and local income taxes 2 (2 ) (2 ) Effect of foreign tax rates (5 ) 13 5 Effect of foreign exchange on functional currencies 2 (8 ) (6 ) Tax credits (12 ) — — Capital gain - timber (15 ) — — Stock-based compensation (2 ) — — Domestic manufacturing deduction (2 ) — — Valuation allowance (12 ) 31 10 Uncertain tax positions 21 (4 ) 1 Other, net — 2 — Effective tax rate (%) 12 % (3 )% (27 )% 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. In June 2015, LP finalized its settlement agreement with the U.S. Internal Revenue Service (IRS) regarding its examination of tax years 2007-2009. U.S. tax years are now closed through 2012, and no examinations are currently in progress. LP remains subject to U.S. federal examinations of tax years 2013 to 2015 as well as state and local tax examination for the tax years 2007-2015. In 2016, Canada completed its examination of tax years 2012 and 2013; tax years 2014 and 2015 are subject to examination. Quebec provincial audits have been effectively settled through 2012. Chilean returns for the 2010 - 2013 tax years have been audited and various issues are currently being appealed in the Chilean courts. Brazilian returns for years 2009 to 2015 are subject to audit but no examinations are currently in progress. 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 2016 2015 2014 Beginning balance $ 4.1 $ 42.2 $ 48.9 Increases: Tax positions taken in current year 26.9 — 0.1 Tax positions taken in prior years 10.4 0.9 1.3 Decreases: Tax positions taken in current year — — — Tax positions taken in prior years — (0.5 ) (8.1 ) Settlements during the year — (34.7 ) — Lapse of statute in current year (1.6 ) (3.8 ) — Ending balance $ 39.8 $ 4.1 $ 42.2 Included in the above balances at December 31, 2016 and 2015 is $39.8 million and $3.7 million of tax benefits that, if recognized, would affect LP’s effective tax rate. LP accrued interest of $3.0 million and paid interest of $0.0 million during 2016 and accrued interest of $0.2 million and paid interest of $4.8 million during 2015 . In total, LP has recognized a liability of $3.0 million and $0.1 million for accrued interest related to its uncertain tax positions as of December 31, 2016 and 2015 . The $34.7 million settlement amount in the above table is the result of LP's 2015 agreement with the Internal Revenue Service regarding their examination of tax years 2007-2009.

These costs are a direct deduction from the carrying amount related to the debt liability. 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 2016, $ 3.0 million of deferred debt costs were written off in association with early debt extinguishment. LP amortized deferred debt costs of $1.1 million , $1.1 million and $1.2 million for the years ended December 31, 2016 , 2015 and 2014 . Included in these amortized amounts are deferred debt costs associated with our current line of credit, which is recorded as an "Other Asset" LP's Consolidated Balance Sheet. 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 $23.4 million and $23.1 million at December 31, 2016 and 2015 . LP estimated the Senior Notes due in 2024 to have a fair value of $344.3 million at December 31, 2016 and its Senior Notes due in 2020 to have a fair value of $366.2 million at December 31, 2015 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. 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 were originally scheduled to mature in 2018. The notes were supported by a bank letter of credit. LP’s reimbursement obligations under the letter of credit were secured by $ 410.0 million in notes receivable from assets sales. In August 2016, LP gave a binding notice to the note holder that LP would pay the notes, $ 368.7 million , plus accrued interest upon receipt of the proceeds for the notes receivable. LP received the proceeds of the notes receivable and subsequently paid the non-recourse notes in full in November 2016. 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, 2016 and 2015 , no revolving borrowings had been made or were outstanding under the credit facility. Certain of LP’s existing and future wholly owned domestic subsidiaries guaranty LP’s obligations under the credit facility and, subject to certain limited exceptions, provide security through a lien on substantially all of the personal property of these subsidiaries. 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 $200 million thereafter, in each case calculated in the manner specified in the credit agreement. As of December 31, 2016 , 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 an optional prepayment of $ 6.8 million during 2016. The impact of foreign currency exchange rates in 2016 was $1.0 million which included a UF change of $0.3 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 2016 , LP made principal payments of $ 2.0 million . In May 2012, LP issued $350.0 million aggregate principal of 7.5% Senior Notes due 2020. In September 2016, LP announced the commencement of a cash tender offer for any and all of its outstanding of 7.5% Senior Notes due 2020 for a purchase price of $1,041.75 for each $1,000 principal amount of 2020 Notes. LP purchased $ 262.4 million aggregate principal amount (or approximately 75%) of the 2020 Notes in September 2016. The remaining $ 87.6 million plus accrued interest were redeemed in October 2016. LP recorded a loss on early debt extinguishment of $ 17.4 million , which included $ 2.9 million associated with the unamortized financing costs associated with these 2020 notes. In September 2016, LP issued $ 350.0 million aggregate principal of 4.875% Senior Notes due 2024. On or after September 15, 2019, LP may, at its option on one or more occasions, redeem all or any portion of these notes at specified redemption rates. Obligations under the indenture governing LP's notes are unsecured and not presently guaranteed by any of LP's 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, 2016 and 2015 was approximately 5.1% and 4.0% . Required repayment of principal for long-term debt is as follows: Dollar amounts in millions Years ending December 31, 2017 $ 2.6 2018 24.9 2019 4.8 2020 — 2021 — 2022 and after 350.0 Total $ 382.3 Cash paid during 2016 , 2015 and 2014 for interest (net of capitalized interest) was $27.2 million , $36.9 million and $30.8 million .

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 78% of the assets and 84% 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 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 certain executives. Benefits are generally based on compensation in the years immediately preceding normal retirement. During the year ended December 31, 2015, LP recorded a plan settlement charge of $0.8 million associated with the retirement of two of LP's executives during 2015. 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 2016 2015 2014 Service cost $ 4.3 $ 3.8 $ 3.5 Interest cost 13.1 13.1 14.1 Expected return on plan assets (13.1 ) (15.0 ) (16.9 ) Amortization of prior service cost and net transition asset 0.5 0.5 — Amortization of net actuarial loss 5.4 6.8 5.5 Net periodic pension cost $ 10.2 $ 9.2 $ 6.2 Loss (gain) due to settlement $ — $ 0.8 $ — Discount rate 4.1 % 3.8 % 4.6 % Weighted rate of compensation increase 0.7 % 0.7 % 0.8 % Weighted expected return on plan assets 5.4 % 6.0 % 6.7 % Other changes in plan assets and benefit obligations recognized in other comprehensive income (OCI): Year ended December 31, Dollar amounts in millions 2016 2015 2014 Net actuarial (gain) loss $ 4.8 $ 0.8 $ 44.2 Amortization of net actuarial loss (5.4 ) (7.6 ) (5.5 ) Amortization of prior service cost (0.5 ) (0.5 ) 9.4 Foreign exchange rate changes — (0.1 ) — Total recognized in OCI $ (1.1 ) $ (7.4 ) $ 48.1 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 to its qualified U.S. defined benefit pension plans. 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: December 31, Dollar amounts in millions 2016 2015 Change in benefit obligation: Beginning of year balance $ 330.8 $ 364.1 Service cost 4.3 3.8 Interest cost 13.1 13.1 Actuarial (gain)/loss 3.5 (19.4 ) Foreign exchange rate changes 1.6 (9.7 ) Benefits paid (21.4 ) (21.1 ) End of year balance $ 331.9 $ 330.8 Change in assets (fair value): Beginning of year balance $ 237.4 $ 268.0 Actual return on plan assets 11.8 (5.2 ) Employer contribution 10.5 4.9 Foreign exchange rate changes 1.6 (9.2 ) Benefits paid (21.4 ) (21.1 ) End of year balance $ 239.9 $ 237.4 Funded status $ (92.0 ) $ (93.4 ) Weighted average assumptions for obligations as of measurement date Discount rate for obligations 3.9 % 3.8 % Rate of compensation increase 0.7 % 0.6 % The amounts recognized in LP’s Consolidated Balance Sheets as of December 31 consist of the following: Dollar amounts in millions 2016 2015 Noncurrent pension assets, included in “Other assets” $ 0.9 $ 0.5 Current pension liabilities, included in “Accounts payable and accrued liabilities” (0.2 ) (3.7 ) Noncurrent pension liabilities, included in “Other long-term liabilities” (92.7 ) (90.2 ) Total $ (92.0 ) $ (93.4 ) Amounts recognized in other comprehensive income—pre-tax Net actuarial loss $ 140.6 $ 140.8 Prior service cost 8.4 9.0 Total $ 149.0 $ 149.8 The total accumulated benefit obligation for all pension plans as of December 31, 2016 and 2015 was $326.8 million and $328.2 million . The accumulated benefit obligation and fair value of plan assets for pension plans with accumulated benefit obligations in excess of plan assets were $284.0 million and $194.2 million at December 31, 2016 and $316.6 million and $194.6 million at December 31, 2015 . The projected benefit obligations and fair value of plan assets of plans with projected benefit obligations in excess of plan assets were $287.1 million and $194.2 million at December 31, 2016 and $319.6 million and $194.6 million at December 31, 2015 . The amounts of accumulated other comprehensive income that is expected to be amortized as expense during 2017 is: Dollar amounts in millions Net actuarial loss $ 6.0 Prior service cost 0.5 Total $ 6.5 The benefits expected to be paid from the benefit plans, which reflect expected future service, are as follows: Dollar amounts in millions Year 2017 19.7 2018 29.8 2019 19.4 2020 20.5 2021 20.4 2022– 2026 103.7 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 2016 Actual Allocation 2016 2015 Asset category US Plans Equity securities 40 % 40 % 38 % Debt securities 20 % 20 % 17 % Multi-Strategy Funds 40 % 40 % 45 % Other, including cash and cash equivalents — % — % — % Total Allocation for US Plans 100 % 100 % 100 % Non-US Plans Equity securities 27 % 29 % 28 % Debt securities 71 % 70 % 71 % Other, including cash and cash equivalents 2 % 1 % 1 % Total Allocation for Non-US Plans 100 % 100 % 100 % 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 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, 2016 and December 31, 2015 , fair value asset categories and the level of inputs as defined in Note 3 are as follows: Dollar amounts in millions Asset Category December 31, 2016 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Equity investment funds: (a) Domestic stock funds $ 51.3 $ 38.0 $ 13.3 $ — International stock funds 38.5 13.5 25.0 — Fixed income investment funds: (b) Domestic bond funds 36.8 36.8 — — International bond funds 36.0 — 36.0 — Multi-strategy funds (c) 75.1 62.9 — 12.2 Cash & cash equivalents 2.2 — 2.2 — Total $ 239.9 $ 151.2 $ 76.5 $ 12.2 _______________ (a) Equity investments include investments in funds that are primarily invested in large capitalization U.S. and international equity securities and a mutual fund.

(c) The multi-strategy funds invest in various hedge funds that employ a fund of funds strategy. 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. Dollar amounts in millions Multi-Strategy Funds Balance at January 1, 2015 $ 26.1 Total unrealized gains (losses) — Contribution (redemption) (13.0 ) Management fees 0.2 Balance at December 31, 2015 $ 13.3 Total unrealized gains (losses) $ 0.3 Contribution (redemption) (1.5 ) Management fees 0.1 Balance at December 31, 2016 $ 12.2 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 5.0% 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 1.9 million shares of LP common stock that represented approximately 10.0% of the total market value of plan assets at December 31, 2016 . 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 2016 , 2015 and 2014 were $8.7 million , $8.0 million and $5.6 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, 2016 and 2015 was $7.8 million and $7.5 million . Net expense related to these plans was not significant in 2016 or 2015 . 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 I.R.S. 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 $1.8 million and $2.0 million at December 31, 2016 and December 31, 2015 and is included in “Other long-term liabilities” on LP’s Consolidated Balance Sheets.

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, 2016 , 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 , 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. Common Stock Plan LP has a stock-based compensation plan under which stock option, SSARs, incentive shares, restricted stock and performance shares awards are granted. At December 31, 2016 , 3.3 million shares were available under the current plan for these awards. Year ended December 31, Dollar amounts in millions 2016 2015 2014 Total stock-based compensation expense (costs of sales and general and administrative) $ 13.0 $ 9.3 $ 9.4 Income tax benefit related to stock-based compensation $ 3.4 Impact on cash flow due to taxes paid related to net share settlement of equity awards $ 9.2 $ 6.1 $ 1.5 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 2016 , 2015 and 2014 based on its historical experience during the preceding three years. Stock-Settled Stock Appreciation Rights LP grants SSARs to key employees. On exercise, LP generally issues these shares from treasury. The SSARs are granted at market price at the date of grant. SSARs become exercisable over three years and expire ten years after the date of grant. The following table sets out the weighted average assumptions used to estimate the fair value of the SSARs granted using the Black-Scholes option-pricing model: 2016 2015 2014 Expected stock price volatility 45 % 54 % 57 % Expected dividend yield — % — % — % Risk-free interest rate 1.4 % 1.5 % 1.5 % Expected life of options (in years) 6.0 years 6.0 years 5.0 years Weighted average fair value of options and SSARs granted $ 6.99 $ 8.80 $ 9.03 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 SSARs: 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, 2016 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) Outstanding at January 1, 2014 6,937 $ 14.26 Granted 494 $ 18.09 Exercised (43 ) $ 9.92 Canceled (384 ) $ 21.14 Outstanding at December 31, 2014 7,004 $ 14.19 Granted 378 $ 17.04 Exercised (1,334 ) $ 10.76 Canceled (309 ) $ 25.83 Outstanding at December 31, 2015 5,739 $ 14.54 Granted 509 $ 15.74 Exercised (1,593 ) $ 7.84 Canceled (426 ) $ 28.18 Outstanding at December 31, 2016 4,229 $ 15.84 4.3 $ 17.4 Vested and expected to vest at December 31, 2016 (1) 4,181 $ 15.84 4.3 $ 17.3 Exercisable at December 31, 2016 3,352 $ 15.68 3.3 $ 15.3 _______________ (1) 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 2016 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, 2016 . This amount changes based on the market value of LP’s stock as reported by the New York Stock Exchange. As of December 31, 2016 , there was $2.5 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 0.93 years. LP recognized $4.6 million , $3.6 million and 3.8 million in compensation expense associated with these awards for the years ended December 31, 2016 , 2015 and 2014 . Incentive Share Awards LP has granted incentive share stock awards (restricted stock units) to certain key employees and directors. 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 to employees vest three years from the date of grant and to directors over one year. The market value of these grants approximates the fair value. The fair value of the restricted units on the date of the grant is amortized ratably over the service period which is generally three years. LP recorded compensation expense related to these awards in 2016 , 2015 and 2014 of $4.7 million , $3.5 million and $3.0 million . As of December 31, 2016 , there was $4.0 million of total unrecognized compensation cost related to unvested incentive share awards.

Performance Share Awards In 2016, LP awarded performance shares to certain senior key employees. These performance shares are earned based upon LP attaining specified revenue growth rates associated with LP's SmartSide products to overall revenue growth as compared to the prior year. The performance period is measured over 2016 with a subsequent two year vesting period. During 2016, the Company issued 90,444 performance units at an average grant date fair value of $20.45 per share. The aggregate value of these shares were $1.8 million . LP recorded compensation expense related to these awards in 2016 of $1.0 million . Phantom Stock During 2012, LP made annual grants of phantom stock units to its directors. These awards are considered liability awards. The director does not receive rights of a shareholder, nor is any stock transferred. 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, 2016 , phantom stock units covering 31,388 shares were outstanding under this program. Based upon the closing stock price at December 31, 2016 , these shares equate to a cash payment of $0.6 million .

Contingencies Disclosure [Text Block]	CONTINGENCIES LP maintains reserves for various contingent liabilities as follows: December 31, Dollar amounts in millions 2016 2015 Environmental reserves $ 15.9 $ 16.6 Other reserves 0.2 0.2 Total contingencies 16.1 16.8 Current portion (3.4 ) (1.3 ) Long-term portion $ 12.7 $ 15.5 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 $2.0 million of costs, relating to two sites, pursuant to formal cost-sharing arrangements between LP and one or more third parties. • Approximately $2.0 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 $0.3 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 2016 2015 2014 Beginning balance $ 16.6 $ 13.6 $ 14.9 Adjusted to expense (income) during the year 0.7 0.5 1.3 Adjusted to expense (income) through other operating credits and charges, net — 3.2 0.5 Payments made (1.4 ) (0.7 ) (3.1 ) Ending balance $ 15.9 $ 16.6 $ 13.6 During 2016 , 2015 and 2014 , LP adjusted its reserves at a number of sites to reflect current estimates of remediation costs and environmental settlements. During 2015, $3.2 million was adjusted through other operating credits and charges related to an increase in environmental reserves for a site that LP previously operated a vinyl siding operation based upon a revised estimate of the environmental remediation required. 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.

Commitments and Contingencies Disclosure [Abstract]
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 has not accrued any additional amounts as a result of the indemnity agreements summarized below as LP believes the fair value of the guarantees are 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 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. • In connection with the mill exchange by LP Canada of its non-operating OSB mill in Chambord, Quebec to Norbord in November 2016, LP provided an indemnity for liabilities arising out of pre-closing operations. These indemnities are capped at C$5.0 million in 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 2016 2015 2014 Beginning balance $ 21.0 $ 31.4 $ 29.3 Accrued to expense during the year 0.8 0.7 0.6 Accrued/ (credited) to other operating credits and charges 16.9 (1.4 ) 11.3 Accrued to discontinued operations 0.5 2.5 3.0 Foreign currency translation (0.2 ) (0.5 ) (1.2 ) Payments made (14.9 ) (11.7 ) (11.6 ) Total warranty reserves 24.1 21.0 31.4 Current portion of warranty reserves (9.0 ) (6.0 ) (12.0 ) Long term portion of warranty reserves $ 15.1 $ 15.0 $ 19.4 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 2016, LP increased the warranty reserve associated with CanExel products sold in certain geographic areas and for a specific time period by $16.9 million . The changes to the reserve reflected revised estimates of future claims. During 2015, LP decreased the warranty reserve associated with SmartSide products by $1.4 million based upon reduced claims activity. During 2014, LP increased the warranty reserve associated with CanExel products sold in certain geographic areas by $11.3 million . The changes to the reserve reflected revised estimates of future claims. LP increased the warranty reserves related to discontinued composite decking products by $0.5 million , $2.5 million , and $3.0 million for the years ended December 31, 2016 , 2015 and 2014 . 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. LP believes that the warranty reserve balances at December 31, 2016 are adequate to cover future warranty payments. However, it is possible that additional charges may be required.

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 limited sales to Asia, Australia and Europe. See Note 23 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.
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 income of unconsolidated affiliates” on the Consolidated Statements of Income. See Note 8 for further discussion of these investments and advances. LP has a variable interest in its Abitibi-LP equity method investee but is not considered to be the primary beneficiary.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Cash and cash equivalents includes cash on hand and short-term investments of 3 months or less when purchased. 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. 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. Inventory consists of the following: December 31, Dollar amounts in millions 2016 2015 Logs $ 54.6 $ 58.6 Other raw materials 23.0 21.6 Semi finished inventory 16.8 18.5 Finished products 140.2 123.3 Total $ 234.6 $ 222.0
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, 2016 and 2015 , LP included various non-operating sites in its held for sale category. The current book values of assets held for sale by category is as follows: Dollar amounts in millions December 31, 2016 2015 Property, plant and equipment, at cost: Land, land improvements and logging roads, net of road amortization $ 1.3 $ 1.8 Buildings 0.3 0.5 Machinery and equipment 6.6 6.7 Net property, plant and equipment $ 8.2 $ 9.0 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 $1.9 million in 2016 and 2015 .
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 17 for a discussion of charges in 2016 , 2015 and 2014 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, 2016 , the fair values of LP's facilities were 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, or should changes occur related to LP's wood supply for these locations, 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. 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 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 income 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 performance shares, restricted stock or restricted stock units and stock-settled stock appreciation rights (SSARs), based upon the fair value of those awards at the date of grant over the requisite service period. See Note 14 for further discussion.
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 (related depreciation and amortization on both property, plant and equipment and timber and timberlands), goodwill, and certain other non-monetary assets. 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 and Brazilian subsidiaries are the Chilean peso and Brazilian real 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 income (loss)” in Stockholders’ equity.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill and Intangible assets 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 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 LP's restricted cash accounts generally secure outstanding letters of credit.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition Revenue is recognized when 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 2016 , 2015 and 2014 , LP's top ten customers accounted for approximately 41% , 45% and 41% of its sales. No customers exceeded 10% of LP's sales in 2016, 2015 or 2014. 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 and 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 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.
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 2016 , 2015 and 2014 .
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, costs associated with pension or other post retirement benefits that have not been recognized as components of net periodic benefit costs, and net unrealized gains or losses on securities and is presented in the accompanying Consolidated Statements of Comprehensive Income. See Note 22 for further discussion.
New Accounting Pronouncements, Policy [Policy Text Block]	Present and Prospective Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, "Revenue from Contracts with Customers (Topic 606)", which supersedes the revenue recognition requirements in Accounting Standards Codification (ASC) 605, Revenue Recognition. The new revenue recognition standard requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective on January 1, 2018. LP has elected to adopt the revenue recognition standard in the first quarter of 2018 with a cumulative adjustment to retained earnings. Based upon current interpretations, LP does not anticipate the adoption of this standard to have a material impact on LP’s financial statements. In July 2015, the FASB issued ASU 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory" which requires entities to measure most inventory "at the lower of cost and net realizable value," thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost of market. LP currently values all inventory at the lower of cost of market. The ASU will not apply to inventories that are measured by using the last -in, first out (LIFO), which is the method that LP currently uses for a minor portion of its log inventories. The remaining inventories are valued using first-in, first-out or average cost. This ASU is effective prospectively for annual periods beginning after December 15, 2016 and interim periods therein. The adoption of this standard is not expected to have a material impact on LP's financial condition, results of operations or cash flow. In March 2016, the FASB issued ASU No. 2016-09, "Improvements to Employee Share-based Payment Accounting" which simplifies several aspects of the accounting for employee share-based payment transactions and addresses the presentation of excess tax benefits and employee taxes paid on the statement of cash flows. LP is now required to present excess tax benefits as an operating activity (combined with other income tax cash flows) on the statement of cash flows rather than as a financing activity, and LP has adopted this change prospectively. ASU 2016-09 also requires the presentation of employee taxes as a financing activity on the statement of cash flows, which is where LP has previously classified this item. LP adopted this standard using the modified retrospective approach as of January 1, 2016 and recorded a cumulative-effect adjustment of $16.3 million to increase retained earnings and increase long-term deferred tax asset. In March 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)", which supersedes the lease accounting requirements in ASC Topic 840, Leases. The new standard requires entities to recognize, separately from each other, an asset for its right to use (ROU) the underlying asset equal to the liability for its finance and operating lease obligations. Further, the entity is required to present separately the current and non-current portion of the ROU asset and corresponding lease liability. The new standard is effective on January 1, 2019. LP is currently evaluating the effect that adopting this new accounting guidance will have on its consolidated results of operations and financial position. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classifications of Certain Cash Receipts and Cash Payments." The standard provides guidance for eight changes with respect to how cash receipts and cash payments are classified in the statement of cash flows, with the objective of reducing diversity in practice. The new standard is effective January 1, 2018, with early adoption permitted. LP does not expect the adoption of this new standard to have a material impact on its consolidated results of operations and financial position. In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory." The standard provides guidance that entities recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Consequently, the amendments eliminate the exception for an intra-entity transfer of an asset other than inventory. The new standard is effective for annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual periods beginning after December 15, 2019. Early adoption is permitted for all entities as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance. LP does not expect the adoption of this new standard to have a material impact on its consolidated results of operations and financial position. In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash." This standard provides guidance that requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The new standard is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. LP does not expect the adoption of this new standard to have a material impact on its consolidated results of operations and financial position.
