SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]

Significant Accounting Policies [Text Block]


1.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

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

See Note 24 below for further information regarding LP’s products and segments.

Use of Estimates in the Preparation of Financial Statements

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

Consolidation

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

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

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

Earnings per Share

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

Stock options, warrants and stock settled stock appreciation rights (SSARs) related to approximately 2.5 million and 2.3 million common shares were considered not in-the-money for purposes of LP's earnings per share calculation for the years ended December 31, 2013 and December 31, 2012. Stock options, warrants, stock settled stock appreciation rights (SSARs) and performance shares related to approximately 5.8 million common shares for the year ended December 31, 2014 were considered anti-dilutive for purposes of LP’s earnings per share calculation due to LP’s loss position in continuing operations.

Cash and Cash Equivalents

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

Investments

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

Fair Value of Financial Instruments

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

Inventory

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

Timber and Timberlands

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

Assets Held for Sale

Over the last several years, LP has adopted and implemented plans to sell selected assets in order to improve its operating results. LP is required to classify assets held for sale which are not part of a discontinued business separately on the face of the financial statements outside of “Property, plant and equipment”. During 2014, LP sold the assets of one of its non-operating locations for $11.9 million. As of December 31, 2014 and 2013, LP included two OSB mills and various non-operating sites in its held for sale category. See Note 3 for discussion of impairments recorded on these assets to reduce carrying value to estimated sales prices less estimated selling costs. The current book values of assets held for sale by category is as follows:



Dollar amounts in millions	December 31,
Dollar amounts in millions	2014			2013
Property, plant and equipment, at cost:
Land, land improvements and logging roads, net of road amortization	$	4.5		$	6.9
Buildings	2.9			6.2
Machinery and equipment	52.0			99.1
	59.4			112.2
Accumulated depreciation	(50.1		)	(95.9		)
Net property, plant and equipment	$	9.3		$	16.3

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

Property, Plant and Equipment

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

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

LP capitalizes interest on borrowed funds during construction periods. Capitalized interest is charged to machinery and equipment accounts and amortized over the lives of the related assets. Capitalized interest totaled $1.3 million in 2014 and $1.6 million in 2013.

Potential Impairments

Long-lived assets to be held and used by LP (primarily property, plant and equipment and timber and timberlands) are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. When impairment is indicated, the book values of the assets are written down to their estimated fair value as calculated by the expected discounted cash flow or estimated net sales price. See Note 3 for impairment charges recorded in the periods presented. See Note 17 for a discussion of charges in 2014, 2013 and 2012 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, 2014, the fair values of LP's facilities were substantially in excess of their carrying value, which supported the conclusion that no impairment is necessary for those facilities. However, if demand and pricing for the relevant products continues at levels significantly below cycle average demand and pricing, or should LP decide to invest capital in alternative projects, or should changes occur related to LP's wood supply for these locations, it is possible that impairment charges will be required.

Income Taxes

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

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

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

See Note 10 for further discussion of deferred income taxes.

Stock-Based Compensation

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

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

The functional currencies of LP’s Chilean 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 loss” in Stockholders’ equity.

Goodwill

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

Intangible Assets

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

Restricted Cash

In accordance with LP’s credit facilities, discussed at Note 12, LP has established restricted cash accounts. As of December 31, 2014, a portion of the restricted cash secures outstanding letters of credit under LP’s U.S. and Canadian credit facilities.

Revenue Recognition

Revenue is recognized when 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 2014, 2013 and 2012, LP's top ten customers accounted for approximately 41%, 44% and 46% of its sales. During 2012, Home Depot, Inc. accounted for more than 10% of its sales with no customers exceeding 10% in 2013 or 2014.

Pricing and Sales Incentives

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

Asset Retirement Obligations

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

Deferred Debt Costs

Deferred debt costs are amortized over the life of the related debt using a straight line basis which approximates the effective interest method. If the debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired to other non-operating income (expense). During 2013, $1.4 million and during 2012, $4.5 million of deferred debt costs were written off in association with the early debt extinguishment. LP amortized deferred debt costs of $1.2 million, $1.4 million and $1.5 million for the years ended December 31, 2014, 2013 and 2012. See Note 11 for further discussion.

Other Operating Credits and Charges, Net

LP classifies significant amounts that management considers unrelated to ongoing core operating activities as “Other operating credits and charges, net” in the Consolidated Statements of Income. Such items include, but are not limited to, amounts related to restructuring charges (including severance charges), charges to establish and maintain litigation or environmental reserves, product reserves, prior year inventory profit adjustments, retirement charges and gains or losses from settlements with governmental or other organizations. Due to the nature of these items, amounts in the income statement can fluctuate from year to year. The determination of which items are considered significant and unrelated to core operations is based upon management’s judgment. See Note 16 for a discussion of specific amounts in 2014, 2013 and 2012.

Retirement Benefits

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

Comprehensive Income

Comprehensive income consists of net income (loss) and other gains and losses affecting shareholders’ equity that are excluded from net income (loss), including foreign currency translation adjustments, prior service costs and credits, transition assets or obligations associated with pension or other post retirement benefits that have not been recognized as components of net periodic benefit costs, net unrealized gains or losses on securities, and unrealized gains and losses on financial instruments qualifying for cash flow hedge accounting, and is presented in the accompanying Consolidated Statements of Comprehensive Income. See Note 22 for further discussion.

Present and Prospective Accounting Pronouncements

In August 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which requires management to evaluate whether conditions exist which raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year of when the financial statements are available to be issued). If such conditions exist, disclosure is required of: (1) the principal conditions; (2) management’s evaluation of the significance of the conditions on the entity’s ability to meet obligations; and (3) management’s plans to alleviate this substantial doubt related to the ability to continue as a going concern. If management’s plans do not alleviate this substantial doubt, management must specifically disclose that there is substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or date the financial statements are available to be issued), in addition to the disclosure noted above. This guidance becomes effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter.

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. ASU 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2016. LP is currently evaluating the effect that adopting this new accounting guidance will have on its consolidated results of operations and financial position.

In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This guidance states that the disposal of a component of an entity is to be reported in discontinued operations only if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. The pronouncement also requires additional disclosures regarding individually significant disposals of components that do not meet the criteria to be recognized as a discontinued operation as well as additional and expanded disclosures. The guidance is effective for all disposals (or classifications as held for sale) of components of an entity and all businesses or nonprofit activities that, on acquisition, are classified as held for sale that occur within annual periods beginning on or after December 15, 2014, and interim periods within annual periods beginning on or after December 15, 2015; it is applied prospectively. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The adoption of this standard will impact presentation only and will not have an effect on LP's consolidated results of operations and financial position.

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, 2014 and December 31, 2013:



Dollar amounts in millions	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Fair Value
December 31, 2014
Auction rate securities	$	0.3	$	4.3	$	—	$	4.6

Total marketable securities	$	0.3	$	4.3	$	—	$	4.6

Auction rate securities	$	0.4	$	3.3	$	—	$	3.7

Total marketable securities	$	0.4	$	3.3	$	—	$	3.7

As of December 31, 2014, LP had $4.6 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.

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

The contractual maturities of debt securities classified as available for sale at December 31, 2014 were as follows:



Dollar amounts in millions	2014
Dollar amounts in millions	Amortized Cost		Fair Value
Due in one year or less	$	—	$	—

Fair Value Measurements

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, 2014 and 2013 is summarized in the following tables.



Dollar amounts in millions	December 31, 2014		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	$	4.6	$	—	$	—	$	4.6
Trading securities	2.3		2.3		—		—
Contingent consideration	0.2		—		—		0.2



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

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

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

The following table summarizes changes in assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the twelve months ended December 31, 2014 and 2013.

LP estimated the Senior Notes maturing in 2020 to have a fair value of $371.0 million at December 31, 2014 and $390.3 million at December 31, 2013 based upon market quotations.

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

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

During 2014, LP recognized a gain of $3.2 million as a fair value adjustment to the contingent consideration payable in connection with a business combination (see Note 23 for further discussion). The fair value of the contingent consideration was reduced during the year due to the decline in projected OSB prices as compared to the initial fair value which was established at the date of the acquisition. This reduction resulted in lowering the estimated payment obligation. The fair value adjustment is recorded in Other Operating Credits and Charges, Net (see Note 16 for further discussion). This fair value was determined based upon the income approach using significant non-observable inputs such as projected OSB pricing taking into consideration volatility of such projections.

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

The $134.0 million of benefit relating to capital loss and net operating loss (NOL) carryovers included in the above table at December 31, 2014 consists of $36.1 million for federal NOL carryovers which will begin to expire in 2031, $31.8 million (net of federal taxes) for state NOL carryovers and $0.9 million for state capital losses which will expire in various years 2015 through 2033, $54.3 million for Canadian NOL carryovers which will expire starting in 2029 and $10.9 million for Canadian capital loss carryovers which may be carried forward indefinitely. At December 31, 2014, LP has recorded valuation allowances of $9.9 million related to state NOL carryover benefit; $0.9 million related to state capital loss carryover; $5.6 million related to Canadian NOL carryover; $13.7 million against the Canadian capital loss benefit; $0.8 million against the state tax credit carryovers and $1.4 million related to other items.

LP periodically reviews the need for valuation allowances against deferred tax assets and recognizes these deferred tax assets to the extent that their realization is more likely than not. As part of our review, we consider all positive and negative evidence, including earnings history, the future reversal of deferred tax liabilities, and the relevant expirations of carry forwards. LP believes that the valuation allowances provided are appropriate. If future years’ earnings differs 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.

In 2013, LP decreased its previously recorded valuation allowance against its state and Canadian deferred tax assets by approximately $22.1 million based on 2013 current operating results and an increase in deferred tax liabilities.

As a result of certain realization requirements of ASC 718 Compensation -- Stock Compensation, the table of deferred tax assets and liabilities shown above does not include $13.9 million and $13.2 million of deferred tax assets as of December 31, 2014 and December 31, 2013 that arose directly from tax deductions related to amounts of equity compensation that are greater than the compensation recognized for financial reporting. Equity will be increased if and when such deferred tax assets are ultimately realized. LP uses the "with and without" method for determining when excess tax benefits have been realized. In 2013, LP recognized a current tax benefit of $0.3 million as adjustments to additional paid in capital arising from tax deductions for equity compensation that were more than the compensation recognized for financial reporting.

U.S. taxes have not been provided on approximately $51.0 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,

LP and its domestic subsidiaries are subject to U.S. federal income tax as well as income taxes of multiple state jurisdictions. Its foreign subsidiaries are subject to income tax in Canada, Chile, Peru and Brazil. During 2011, the U.S. Internal Revenue Service initiated an audit of tax years 2007 through 2009. LP protested certain proposed adjustments and requested review by the IRS Appeals Office. In the fourth quarter of 2014, the IRS Appeals conferences were completed and a tentative agreement was reached resolving all issues. The agreed upon changes are subject to approval by U.S. Joint Committee on Taxation which is expected to occur in 2015. During 2013, LP deposited $17.1 million with the IRS to suspend the accrual of interest pending the resolution of this matter. The deposit is included within Prepaid and other current assets on the Consolidated Balance Sheet at December 31, 2014.

LP remains subject to U.S. federal examinations of tax years 2011 through 2013 as well as state and local tax examination for the tax years 2007-2013. Canadian federal income tax years are closed through 2009 and no examinations are currently in progress. Quebec provincial audits have been effectively settled through 2012. Chilean returns for the 2010 - 2012 tax years are under review by the Chilean Tax Office. Brazilian returns for years 2009 - 2013 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:

Included in the above balances at December 31, 2014 and 2013 is $14.6 million and $12.8 million of tax benefits that, if recognized, would affect LP’s effective tax rate. LP reversed interest of $1 million during 2014 and accrued interest of $0.2 million during 2013, and in total LP has recognized a liability of $4.7 million and $5.7 million for accrued interest related to its uncertain tax positions as of December 31, 2014 and 2013. While outcomes and timing cannot be predicted, it is possible that unrecognized tax benefits of up to $34.7 million, primarily related to the timing of fixed asset recovery and $4.1 million related to the timing of gain recognition could change as a result of the anticipated settlement of the 2007-2009 IRS audit and the lapse of statutes of limitation, respectively, during the next twelve months.

LP believes the carrying amounts of its variable rate long-term debt approximates fair market value. LP estimated the limited recourse notes payable to have a fair value of approximately $23.2 million and $22.9 million at December 31, 2014 and 2013. LP estimated the senior unsecured notes maturing in 2020 to have a fair value of $371.0 million at December 31, 2014 and $390.0 million at December 31, 2013 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 mature in 2018. The notes are supported by a bank letter of credit. LP’s reimbursement obligations under the letter of credit are secured by $410.0 million in notes receivable from assets sales. In general, the creditors under this arrangement have no recourse to LP’s assets, other than the notes receivable. However, under certain circumstances, LP may be liable for certain liabilities (including liabilities associated with the marketing or remarketing of the notes payable and reimbursement obligations, which are fully cash collateralized, under the letter of credit supporting the notes payable) in an amount not to exceed 10% of the aggregate principle amount of the notes receivable.

In December 2013, LP entered into a credit agreement with various lenders and American AgCredit, PCA, as administrative agent and CoBank, ACB, as letter of credit issuer. The credit agreement provides for a $200 million revolving credit facility, with a $60 million sublimit for letters of credit. The credit facility terminates and all loans made under the credit agreement become due in December 2018. As of December 31, 2013 and 2014, 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. Subject to certain limited exceptions, obligations under the credit facility are secured by a lien on substantially all of the personal property of LP and its subsidiaries that are guarantors under the credit facility.

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

The credit agreement contains various restrictive covenants and customary events of default. The credit agreement also contains financial covenants that require the Company and its consolidated subsidiaries to have, as of the end of each quarter, (i) a capitalization ratio (i.e., funded debt to total capitalization) of no more than 40% and (ii) unrestricted cash and cash equivalents of at least $200 million thereafter, in each case calculated in the manner specified in the credit agreement. As of December 31, 2014, 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 no principal payments during 2014. The impact of foreign currency exchange rates in 2014 was $2.1 million which was offset by a UF change of $0.8 million. LP made principal payments of $21 million during 2013 which included a scheduled payment of $2.6 million and an optional prepayment of $18.4 million. The impact of foreign currency exchange rates in 2013 was $2.8 million which was offset by a UF change of $0.3 million.

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 2014, LP made principal payments of $2.0 million.

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

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

The weighted average interest rate for all long-term debt at December 31, 2014 and 2013 was approximately 3.9 percent for both periods. Required repayment of principal for long-term debt is as follows:

Retirement Plans and Post Retirement Benefits

Compensation and Retirement Disclosure [Abstract]

Retirement Plans and Postretirement Benefits

RETIREMENT PLANS AND POSTRETIREMENT BENEFITS

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

Defined Benefit Plans

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

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

LP also maintains a Supplemental Executive Retirement Plan (SERP), an unfunded, non-qualified defined benefit plan intended to provide supplemental retirement benefits to key executives. Benefits are generally based on compensation in the years immediately preceding normal retirement. LP has established a grantor trust that provides funds for the benefits payable under the SERP. The assets of the grantor trust are invested in corporate-owned life insurance policies. At December 31, 2014 and 2013, the trust assets were valued at $9.7 million and $9.7 million and are included in “Other assets” on the Consolidated Balance Sheets. LP did not contribute to this trust in 2014 or 2013. During the year ended December 31, 2012, LP paid its retiring CEO his accumulated SERP liability of $10.4 million through the use of the assets included in the grantor trust. In connection with this distribution, LP recorded a plan settlement charge of $2.2 million.

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

Settlement	—			—			(2.2		)
Foreign exchange rate changes	—			0.2			—
Total recognized in OCI	$	48.1		$	(43.3	)	$	2.2

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

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

The projected benefit obligation is the actuarial present value of benefits attributable to employee service rendered to date, including the effects of estimated salary increases.

The total accumulated benefit obligation for all pension plans as of December 31, 2014 and 2013 was $361.5 million and $317.7 million.

The accumulated benefit obligation and fair value of plan assets for pension plans with accumulated benefit obligations in excess of plan assets were $348.0 million and $217.9 million at December 31, 2014 and $304.7 million and $256.7 million at December 31, 2013. The projected benefit obligations and fair value of plan assets of plans with projected benefit obligations in excess of plan assets were $350.7 million and $217.9 million at December 31, 2014 and $309.0 million and $256.7 million at December 31, 2013.

The amounts of accumulated other comprehensive income that is expected to be amortized as expense during 2015 is:

2020 – 2024	108.1

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 2014		Actual Allocation
	Target Allocation 2014		2014		2013

Total	100.0	%	100.0	%	100.0	%

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

The fair value of LP’s pension plan assets at December 31, 2014 and December 31, 2013, fair value asset categories and the level of inputs as defined in Note 3 are as follows:

Level 1 investments are valued based on active market quotations.

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

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

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

Defined Contribution Plans

LP also sponsors defined contribution plans in the U.S. and Canada. In the U.S., these plans are primarily 401(k) plans for hourly and salaried employees that allow for pre-tax employee deferrals and a company match of up to 3.5% of an employee’s eligible wages (subject to certain limits). Under the profit sharing feature of these plans, LP may elect to contribute a discretionary amount as a percentage of eligible wages. Included in the assets of the 401(k) and profit sharing plans are 2.5 million shares of LP common stock that represented approximately 12.4% of the total market value of plan assets at December 31, 2014.

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 2014, 2013 and 2012 were $5.6 million, $8.3 million and $5.2 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, 2014 and 2013 was $8.0 million and $8.2 million. Net expense related to these plans was not significant in 2014 or 2013.

Effective August 16, 2004, LP adopted the Louisiana-Pacific Corporation 2004 Executive Deferred Compensation Plan (the Plan). Pursuant to the Plan, certain management employees are eligible to defer up to 90% of their regular salary and annual cash incentives that exceed the limitation as set forth by the Internal Revenue Service. Each plan participant is fully vested in all employee deferred compensation and earnings credited associated with employee contributions. Employer contributions and associated earnings vest over periods not exceeding five years. The liability under this plan amounted to $2.1 million and $1.9 million at December 31, 2014 and December 31, 2013 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, 2014, 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.

Warrants

During 2009, LP issued warrants to purchase 18,395,963 shares of LP common stock at an exercise price of $1.39 per share subject to mandatory cashless exercise provisions. During the years ended December 31, 2014 and December 31, 2013, warrant exercises resulted in the issuances of 799,488 and 1,621,362 shares. At December 31, 2014, the remaining outstanding warrants were exercisable to purchase approximately 573,520 shares. The warrants (at date of grant) were valued based upon Black-Scholes option pricing model using expected stock price volatility of 53%; no expected dividends; risk-free interest rate of 2.6%; and an expected life of 8 years, which resulted in a fair value per share of $0.72.

Common Stock Plans

At December 31, 2014, LP had stock-based employee compensation plans as described below. The total compensation expense related to all of LP’s stock-based compensation plans was $9.4 million, $8.8 million and 8.4 million for the years ended December 31, 2014, December 31, 2013 and December 31, 2012.

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 2014, 2013 and 2012 based on its historical experience during the preceding three years.

Stock Compensation Plans

LP grants stock settled appreciation rights (SSARs) to key employees. On exercise or issuance, LP generally issues these shares from treasury. The options and SSARs are granted at market price at the date of grant. For employees, options and SSARs become exercisable over three years and expire ten years after the date of grant. At December 31, 2014, 5.2 million shares were available under the current stock award plans for stock-based awards. The following table sets out the weighted average assumptions used to estimate the fair value of the options and SSARs granted using the Black-Scholes option-pricing model:



	2014			2013			2012
Expected stock price volatility	57		%	69		%	64		%
Expected dividend yield	—		%	—		%	—		%
Risk-free interest rate	1.5		%	0.9		%	0.7		%
Expected life of options (in years)	5.0 years			5.0 years			5.1 years
Weighted average fair value of options and SSARs granted	$	9.03		$	11.68		$	4.75

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

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

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

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

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

The following table summarizes stock options and SSARs outstanding as of December 31, 2014 as well as activity during the three year period then ended.

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

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between LP’s closing stock price on the last trading day of 2014 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, 2014. This amount changes based on the market value of LP’s stock as reported by the New York Stock Exchange.

As of December 31, 2014, there was $4.4 million of total unrecognized compensation costs related to stock options and SSARs. These costs are expected to be recognized over a weighted-average period of 1.3 years. LP recognized $3.8 million, $3.4 million and $3.7 million in compensation expense associated with these awards for the years ended December 31, 2014, 2013 and 2012.

Incentive Share Awards

LP has granted incentive share stock awards (restricted stock units) to certain key employees and directors as allowed under the current stock award plans. The awards entitle the participant to receive a specified number of shares of LP common stock at no cost to the participant. Awards granted under this plan vest three years from the date of grant. The market value of these grants approximates the fair value. LP recorded compensation expense related to these awards in 2014, 2013 and 2012 of $3.0 million, $2.7 million and $2.3 million. As of December 31, 2014, there was $3.5 million of total unrecognized compensation cost related to unvested incentive share awards. This expense will be recognized over a weighted-average period of 1.0 year.

The following table summarizes incentive share awards outstanding as of December 31, 2014 as well as activity during the three year period then ended.

Restricted Stock

LP grants restricted stock to certain senior executive employees. The shares vest three years from the date of grant. During the vesting period, the participants have voting rights and receive dividends, but the shares may not be sold, assigned, transferred, pledged or otherwise encumbered. Additionally, granted but unvested shares are forfeited upon termination of employment. The fair value of the restricted shares on the date of the grant is amortized ratably over the vesting period which is generally three years. As of December 31, 2014, there was $2.4 million of total unrecognized compensation costs related to restricted stock. This expense will be recognized over the next 0.9 year.

The following table summarizes restricted stock awards outstanding as of December 31, 2014 as well as activity during the three year period then ended.

LP recorded compensation expense related to these awards in 2014, 2013 and 2012 of $2.1 million, $2.1 million, and $1.8 million.

Performance Share Awards

In connection with Mr. Stevens' appointment to Chief Executive Officer on May 4, 2012, he was awarded 300,000 performance shares. This award was granted pursuant to the terms of LP's 1997 Incentive Stock Award Plan. If pre-determined market-based performance goals are met, shares of LP's stock will be issued to Mr. Stevens based upon a pre-determined vesting schedule based upon the required service periods. The fair market value of this award was determined based on the fair value as of the date of grant times the number of shares adjusted for the weighted probability of the attainment of certain performance goals. LP recorded compensation expense related to these awards of $0.4 million in 2014. As of December 31, 2014, the performance target for 200,000 performance shares was met. As of December 31, 2014, there was $0.5 million of total unrecognized compensation expense related to this award. This expense will be recognized over the next 1.3 years.

Phantom Stock

During 2011 and 2012, LP made annual grants of phantom stock units to its directors. Subsequent to the approval of the 2013 Omnibus Plan in May 2013, phantom stock units are no longer granted to directors. The awards are considered liability awards. The director does not receive rights of a shareholder, nor is any stock transfered. The units will be paid in cash at the end of the five year vesting period. The value of one unit is based on the market value of one share of common stock on the vesting date. The cost of the grants is recognized over the vesting period and is included in stock-based compensation expense. As of December 31, 2014, LP had phantom stock units covering 66,339 shares outstanding under this program. During 2014, LP paid $0.2 million due to retirement of one of its directors. LP recorded compensation expense related to these awards of $0.1 million in 2014.

CONTINGENCIES

LP maintains reserves for various contingent liabilities as follows:



	December 31,
Dollar amounts in millions	2014			2013
Environmental reserves	$	13.6		$	14.9
Other reserves	0.6			0.4
Total contingencies	14.2			15.3
Current portion	(2.0		)	(2.0		)
Long-term portion	$	12.2		$	13.3

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 $2.3 million of costs, relating to three sites, pursuant to formal cost-sharing arrangements between LP and one or more third parties.


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


•	Approximately $0.2 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	2014			2013			2012
Beginning balance	$	14.9		$	14.1		$	15.0
Adjusted to expense (income) during the year	1.3			1.3			0.7
Payments made for claims	(3.1		)	(0.5		)	—

Payments made for administrative costs	—			—			(1.6		)
Ending balance	$	13.6		$	14.9		$	14.1

During 2014, 2013 and 2012, LP adjusted its reserves at a number of sites to reflect current estimates of remediation costs and environmental settlements.

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.

- Definition

Commitments Disclosure [Text Block]

COMMITMENTS AND CONTINGENT LIABILITIES

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

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

At December 31, 2014, future minimum annual rent commitments are as follows:



Dollar amounts in millions
Year ended December 31,
2015	$	2.5
2016	2.1
2017	1.7
2018	1.7
2019	1.7
2020 and thereafter	4.4
Total	$	14.1

As of December 31, 2014, LP has entered into non-cancelable subleases for a portion of its corporate headquarters in Nashville, Tennessee. Minimum annual rent commitments have not been reduced by minimum sublease rentals of $0.4 million (in total for all years) due in the future. Rental expense for operating leases amounted to $9.1 million, $9.2 million and $8.3 million in 2014, 2013 and 2012.

Guarantees and Indemnifications

Commitments and Contingencies Disclosure [Abstract]

Guarantees and Indemnifications

GUARANTEES AND INDEMNIFICATIONS

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

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

Indemnities related to the pre-closing operations of sold assets normally do not represent added liabilities for LP, but simply serve to protect the buyer from potential liability associated with the obligations that existed (known and unknown) at the time of the sale. LP records accruals for those pre-closing obligations that are considered probable and estimable. LP 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.

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	2014			2013			2012
Beginning balance	$	29.3		$	21.4		$	30.3
Accrued to expense during the year	3.6			2.7			4.5
Accrued/ (credited) to other operating credits and charges	11.3			17.7			(1.8		)

Current portion of warranty reserves	(12.0		)	(12.0		)	(12.0		)
Long term portion of warranty reserves	$	19.4		$	17.3		$	9.4

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 2014, LP increased the warranty reserve associated with CanExcel products sold in certain geographic areas by $11.3 million. The changes to the reserve reflected revised estimates of future claims.

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

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

LP increased the warranty reserves related to discontinued composite decking products by $3.0 million in 2014 and $2.0 million in 2013. The additional reserves reflect revised estimates of future claim payments based upon an increase in decking warranty claims related to a specific operation and specific time period. During the fourth quarter of 2008, LP established a voluntary recall of the affected decking. During the second quarter of 2009, LP established a formal recall program under the Consumer Products Safety Board requirements for these products. No additional reserve increase was required in connection with the establishment of the formal program. LP continues to monitor warranty and other claims associated with these products and with the recall program (see Note 18) and believe as of December 31, 2014 that the reserves associated with these matters are adequate.

LP believes that the warranty reserve balances at December 31, 2014 are adequate to cover future warranty payments. However, it is possible that additional charges may be required.

Acquisition of Peace Valley OSB (Notes)	12 Months Ended
Acquisition of Peace Valley OSB (Notes)	Dec. 31, 2014
Acquisition of Peace Valley OSB [Abstract]
Business Combination Disclosure [Text Block]	23. ACQUISITION OF PEACE VALLEY OSB On May 31, 2013, LP acquired full control of the Peace Valley OSB joint venture in which LP previously maintained a 50% interest. Peace Valley OSB's results of operations have been fully consolidated in all periods subsequent to May 31, 2013. Since LP previously served as the exclusive distributor of all OSB produced by this venture, this acquisition will not have a material impact on LP's consolidated net sales. Due to LP's pre-existing 50% ownership interest in Peace Valley OSB, this acquisition was accounted for as a step acquisition in accordance with ASC 805, Business Combinations (“ASC 805”). Accordingly, LP recognized a gain of $35.9 million in connection with this transaction to remeasure its 50% ownership interest in Peace Valley at fair value on the acquisition date. The gain is reflected in Other operating credits and charges, net on the Consolidated Statement of Income. The fair value of LP's existing 50% interest ($95.9 million) was determined using a combination of the income and market approach. In completing this valuation, management considered future earnings and cash flow potential of the business, earnings multiples, and recent market transactions of similar businesses. This gain is included in "Non-operating income (expense)." The purchase price of the 50% acquired interest was $74.6 million (including working capital) paid in cash. Additionally, as part of the purchase consideration, LP agreed to pay contingent consideration equal to a pre-defined percentage of the operation's earnings before interest, taxes, depreciation and amortization (EBITDA) over a pre-defined threshold for each of the next three years. As of May 31, 2013, the fair value of the contingent consideration payable was valued at $24.3 million and was recorded in “accounts payable and accrued liabilities” and “other long term liabilities”. The fair value of the contingent consideration payable will be remeasured at the end of each reporting period. The fair value of the contingent consideration payable was remeasured and reduced by $20.5 million and $3.2 million during 2013 and 2014 respectfully. This reduction was due to the decline in projected OSB prices in the near term as compared to the date of acquisition. This reduction in OSB pricing reduces the estimated EBITDA of the operation. Including the 50% interest previously owned by LP, LP acquired net assets of $194.8 million, consisting of $22.7 million in current assets, $146.4 million in fixed asset, $43.8 million of intangible assets (comprised of $34.1 million of timber licenses and $9.7 million of goodwill) and $8.7 million in current liabilities and $9.4 million in long term liabilities. Additional financial information about Peace Valley OSB (e.g., pro forma financial information and allocation of purchase price) is not presented because such information is not material to LP's results of operations and financial position.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).
