NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1 – BASIS FOR PRESENTATION
The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments, except for other operating credits and charges, net referred to in Note 10) necessary to present fairly, in all material respects, the consolidated financial position, results of operations and cash flows of LP and its subsidiaries for the interim periods presented. Results of operations for interim periods are not necessarily indicative of results to be expected for an entire year. For those consolidated subsidiaries in which LP’s ownership interest is less than 100%, the outside shareholders’ interests are shown as non-controlling interest. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in LP’s Annual Report on Form 10-K for the year ended December 31, 2010.
Certain prior year amounts have been reclassified to conform with the current year presentation associated with certain expenses which were previously classified as selling and administrative expenses and now have been classified to cost of good sold. Such reclassification was not considered material.
NOTE 2 – STOCK-BASED COMPENSATION
At September 30, 2011, 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 $1.6 million for the quarter ended September 30, 2011 as compared to $1.7 million for the quarter ended September 30, 2010 and $6.4 million for the nine months ended September 30, 2011 as compared to $7.0 million for the nine months ended September 30, 2010.
Stock Compensation Plans
LP grants options and stock settled stock appreciation rights (SSARs) to key employees and directors to purchase LP common stock. 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, SSARs become exercisable ratably over a three year period and expire ten years after the date of grant. For directors, these options become exercisable in 10% increments every three months, starting three months after the date of grant, and expire ten years after the date of grant. At September 30, 2011, 4,739,880 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 in the first nine months of the respective years noted:

stock price on the last trading day of the third quarter of 2011 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 September 30, 2011. This amount changes based on the market value of LP's stock as reported by the New York Stock Exchange.
As of September 30, 2011, there was $0.9 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 1.4 years. LP recorded compensation expense related to these awards in the first nine months of 2011 of $3.5 million.
Incentive Share Awards
LP has granted incentive share stock awards (restricted stock units) to certain key employees as allowed under the current stock award plans. The awards entitle the participant to receive a specified number of shares of LP common stock at no cost to the participant. The market value of these grants approximates the fair value. LP recorded compensation expense related to these awards in the first nine months of 2011 of $1.9 million. As of September 30, 2011, there was $2.9 million of total unrecognized compensation cost related to unvested incentive share awards. This expense will be recognized over a weighted-average period of 1.3 years.
The following table summarizes incentive share awards outstanding as of September 30, 2011 as well as activity during the nine months then ended.

| Shares |  | Weighted Average Contractual Term (in years) |  | Aggregate Intrinsic Value (in millions)
Incentive share awards outstanding at January 1, 2011 | 955,936 |  |  |  |  |

Restricted Stock
LP grants restricted stock to certain senior 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 generally 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 September 30, 2011, there was $2.3 million of total unrecognized compensation costs related to restricted stock. This expense will be recognized over the next 1.0 years.
The following table summarizes the restricted stock outstanding as of September 30, 2011 as well as activity during the nine months then ended.

| Nine Months ended September 30, 2011
| Number of Shares |  | Weighted Average Grant Date Fair Value
Restricted stock awards outstanding at January 1, 2011 | 783,289 |  |  | $ | 6.31 |
Restricted stock awards granted | 139,239 |  |  | 10.30 |
Restrictions lapsing | (171,800 | ) |  | 15.27 |
Restricted stock awards at September 30, 2011 | 750,728 |  |  | $ | 5.00 |

LP recorded compensation expense related to these awards in the first nine months of 2011 of $1.0 million.
Through 2010, LP annually granted to each director restricted stock or restricted stock units. As of September 30, 2011, LP had 352,178 shares (or restricted stock units) outstanding under this program.
Phantom stock
Beginning in 2011, LP annually grants phantom stock units to its directors. The director does not receive rights of a shareholder, nor is any stock transfered. The units will be paid out 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
8

over the vesting period and is included in stock-based compensation expense. As of September 30, 2011, LP had 39,944 shares outstanding under this program.
NOTE 3 – FAIR VALUE MEASUREMENTS
LP’s investments that are measured at fair value on a recurring basis are categorized below using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs and Level 3 includes fair values estimated using significant non-observable inputs.
The following table summarizes assets measured on a recurring basis for each of the three hierarchy levels presented below.

Dollar amounts in millions | September 30, 2011 |  | 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 | $ | 0.5 |  |  | $ | — |  |  | $ | — |  |  | $ | 0.5 |

Available for sale securities measured at fair value as of September 30, 2011 and December 31, 2010 are recorded in cash and cash equivalents and long-term investments on LP’s consolidated balance sheets. Included in available for sale securities are auction rate securities (ARS).
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. During the third quarter, LP sold ARS of $38.1 million par value for $19.1 million.
Trading securities consist of rabbi trust financial assets which are recorded in other assets in LP’s consolidated balance sheets. The rabbi trust holds the assets of the Louisiana-Pacific Corporation 2004 Executive Deferred Compensation Plan (EDC), a non-qualified deferred compensation plan which allows certain management employees to defer receipt of a portion of their compensation and contribute such amounts to one or more investment funds. 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 measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the periods ended September 30, 2010 and September 30, 2011.

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 investments.
LP reviews the carrying values of long-lived assets (excluding goodwill) to be held and used, for the 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.
The following table summarizes long-lived assets measured on a nonrecurring basis for each of the three hierarchy levels presented below.

Dollar amounts in millions | September 30, 2011 |  |  | Quoted Prices in Active Markets for Identical Assets (Level 1) |  | Significant Other Observable Inputs (Level 2) |  | Significant Unobservable Inputs (Level 3)

During the third quarter of 2011, LP determined that an impairment review was required of its LSL facility located in Houlton, Maine due to continued operating losses which were driven by the significant reductions in current and forecasted housing starts. As a result of this review, LP recognized a pre-tax, non-cash impairment charge of $62.0 million in the third quarter of 2011. The estimated fair value of long-lived assets was calculated based on the income approach using the discounted probability of weighted cash flows taking into account current expectations for asset utilization, housing starts and the remaining useful life of related assets. In addition, liquidation values were considered where appropriate, as well as indicated values from divestiture activities. These assets are included in LP's property plant and equipment (long-lived assets) which are held and used.
Additionally during the third quarter of 2011, LP recorded an impairment charge of $2.4 million on various assets held for sale to reduce their carrying value to the estimated selling price less selling costs. The valuation of these assets was determined based using level two inputs under the market approach. Also, LP recorded an impairment charge of $0.5 million on assets no longer used.
10

For the nine months ended September 30, 2011, in addition to the impairments noted above, LP recorded an impairment charge of $3.6 million to reduce the carrying value of assets held for sale to the estimated selling prices less selling cost. The valuation of these assets was determined using level two inputs under the market approach. Also, LP recorded an impairment charge of $4.4 million on assets no longer used.
During the third quarter of 2010, LP recorded an other-than-temporary impairment charge of $16.9 million to reduce the carrying value of an equity method investment to its estimated net sales price. LP took this action in connection with a decision by its joint venture partner to sell its interest in the joint venture to a third party. Subsequent to the recording of this impairment, the discussions for sale of this investment were terminated. However LP determined based upon market conditions that the reduction in carrying value was still appropriate. The valuation of these assets was determined using level two inputs under the market approach.
Additionally during the third quarter of 2010, LP recorded an impairment charge of $0.9 million on various assets held for sale to reduce their carrying value to the estimated selling price less selling costs. The valuation of these assets was determined based using level two inputs under the market approach.
For the nine months ended September 30, 2010, in addition to the impairment noted above, LP recorded an impairment charge of $1.2 million to reduce the carrying value of the assets held for sale to the estimated selling price less selling cost. The valuation of these assets was determined using level two inputs under the market approach.
NOTE 4 – 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 and director stock options, stock settled stock appreciation rights, incentive 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:

For the quarter and nine month period ended September 30, 2011, stock options, stock warrants and SSARs relating to approximately 5.9 million and 7.3 million shares of LP common stock were considered anti-dilutive for purposes of LP’s earnings per share calculation due to LP’s loss position from continuing operations. For the quarter and nine month period ended September 30, 2010, stock options, stock warrants and SSARs relating to approximately 15.6 million shares of LP common stock were considered anti-dilutive for purposes of LP’s earnings per share calculation due to LP’s loss position from continuing operations.
During the nine month period ended September 30, 2011, LP issued 5.0 million shares associated with the exercise of stock warrants. The warrants have an exercise price of $1.39 per share subject to mandatory cashless exercise provisions. At September 30, 2011, the remaining outstanding warrants were exercisable to purchase approximately 3.9 million shares, at an exercise price of $1.39 per share subject to mandatory cashless exercise provisions.
NOTE 5 – RECEIVABLES

Total | $ | 156.0 |  |  | $ | 151.9 |

NOTE 7 – 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 September 30, 2011 and December 31, 2010, LP included three 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 sales prices less estimated selling costs. The current book values of assets held for sale by category is as follows:

Dollars in millions | September 30, 2011 |  | December 31, 2010
Property, plant and equipment, at cost: |  |  |
Land, land improvements and logging roads, net of road amortization | $ | 13.8 |  |  | $ | 13.4 |
Buildings | 24.0 |  |  | 24.5 |

| 217.3 |  |  | 235.6 |
Accumulated depreciation | (164.6 | ) |  | (177.7 | )
Net property, plant and equipment | $ | 52.7 |  |  | $ | 57.9 |

NOTE 8 – INCOME TAXES
Accounting standards state that companies account for income taxes using the asset and liability approach, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. This method also requires the recognition of future tax benefits,
11

such as net operating loss carryforwards and other tax credits. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. Valuation allowances are recorded as necessary to reduce deferred tax assets to the amount thereof that is more likely than not to be realized. The likelihood of realizing deferred tax assets is evaluated by, among other things, estimating future taxable income to which the deferred tax assets may be applied and assessing the impact of tax planning strategies.
For interim periods, accounting standards require that income tax expense be determined by applying the estimated annual effective income tax rate to year-to-date results unless this method does not result in a reliable estimate of year-to-date income tax expense. Each quarter the income tax accrual is adjusted to the latest estimate and the difference from the previously accrued year-to-date balance is adjusted to the current quarter.
For the first nine months of 2011, the primary differences between the U.S. statutory rate of 35.0% and the effective rate applicable to LP’s continuing operations relate to state income taxes, the effect of foreign tax rates and increases in valuation allowances attributed to net operating loss carryforwards in various jurisdictions. For the first nine months of 2010, the primary differences between the U.S. statutory rate of 35% and the effective rate applicable to LP’s continuing operations relate to state income taxes, the effect of foreign tax rates and a discrete adjustment for state income taxes.
The income tax components and associated effective income tax rates for the quarter and nine months periods ended September 30, 2011 and 2010 are as follows:

| Quarter Ended September 30,
| 2011 |  | 2010
Dollars in millions | Tax Benefit |  | Tax Rate |  | Tax Benefit |  | Tax Rate
Continuing operations | $ | (20.9 | ) |  | 26 | % |  | $ | (16.4 | ) |  | 35 | %
Discontinued operations | (4.0 | ) |  | 39 | % |  | (0.5 | ) |  | 39 | %
| $ | (24.9 | ) |  | 28 | % |  | $ | (16.9 | ) |  | 35 | %
| Nine Months Ended September 30,

| Tax Benefit |  | Tax Rate |  | Tax Benefit |  | Tax Rate
Continuing operations | $ | (36.1 | ) |  | 24 | % |  | $ | (14.0 | ) |  | 32 | %
Discontinued operations | (5.6 | ) |  | 39 | % |  | (1.4 | ) |  | 39 | %
| $ | (41.7 | ) |  | 25 | % |  | $ | (15.4 | ) |  | 32 | %

LP and its domestic subsidiaries are subject to U.S. federal income tax as well as income taxes of multiple state jurisdictions. LP’s foreign subsidiaries are subject to income tax in Canada, Chile and Brazil. During 2011, the U.S. Internal Revenue Service initiated an audit of tax years 2007 through 2009. All U.S. federal audits of prior years have been completed. LP remains subject to state and local tax examinations for the tax years 2005 through 2010. LP’s Canadian income tax returns have been audited and effectively settled through 2004. Quebec provincial audits have been effectively settled through 2007. No Canadian federal or provincial audits are currently in progress.
If LP were to determine that it would not be able to realize a portion of an existing net deferred tax asset for which there is currently no valuation allowance, an adjustment to the net deferred tax asset would be charged to earnings in the period in which such determination was made. Conversely, if it were to make a determination that it is more likely than not that an existing deferred tax asset for which there is currently a valuation allowance would be realized, the related valuation allowance would be reduced and a benefit to earnings would be recorded in the period in which such determination was made.
NOTE 9 – LONG-TERM DEBT
LP’s long-term debt consists of the following:

LP issued $47.9 million of senior notes in 1997 in a private placement to institutional investors. The $7.9 million remaining notes are secured by $9.9 million in notes receivable from Sierra Pacific Industries and mature in 2012. In the event of a default by Sierra Pacific Industries, LP is fully liable for the notes payable with the underlying timberlands as security for the notes receivable.
LP issued $348.6 million of senior debt in 1998 in a private placement to institutional investors. The remaining $112.0 million of these notes mature in principal amounts of $90.0 million in 2013 and $22.0 million in 2018. The remaining notes are secured by $113.7 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 with the underlying timberlands as security for the notes receivable.
LP issued $368.7 million of senior debt 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 principal amount of the notes receivable. LP’s maximum exposure in this regard was approximately $41.0 million as of September 30, 2011 and December 31, 2010.
In December 2009, LP entered into a term loan agreement with a Chilean bank. This loan is denominated in UF (inflation adjusted Chilean pesos) and is partially secured by property, plant and equipment in Chile. The loan will be repaid in 16 equal semi-annual payments beginning in June 2012 and ending December 2019. As of September 30, 2011, no principal payments have been made on this loan. Any increases or decreases in the loan balance shown are related to the change in the underlying foreign currency exchange rates or required inflation adjustments.
In August 2011, LP entered into a export financing loan agreement with a Brazilian bank. This loan will be repaid in 10 equal semi-annual payments beginning in January 2013 and ending July 2017.
Subsequent to September 30, 2011, LP entered into an amendment to its credit facility which (1) extends the maturity from September 10, 2012 to October 14, 2016, (2) decreases the interest rate payable for certain types of loans, (3) permits LP to include in its borrowing base certain inventory that was previously excluded, (4) increases LP's flexibility to incur and prepay certain debt and (5) provides that the credit facility lenders' second priority liens on certain assets of LP and its subsidiaries that secure certain indebtedness of LP and its subsidiaries to other parties on a first priority basis will be automatically released in connection with the repayment of such other indebtedness.
LP estimates the senior secured notes maturing in 2017 to have a fair value of $234.0 million as of September 30, 2011 and $263.0 million at December 31, 2010 based upon market quotations.
Additional descriptions of LP’s indebtedness are included in consolidated financial statements and the notes thereto included in LP’s Annual Report on Form 10-K for the year ended December 31, 2010.

During the third quarter of 2011, LP recorded a loss of $0.4 million associated with severance related to a recently indefinitely curtailed OSB mill in British Columbia, Canada. LP expects to record an additional $1.4 million over the fourth quarter of 2011 and the first quarter of 2012 in connection with this closure. LP also recorded a loss of $0.5 million associated with an assessment in connection with one of its indefinitely curtailed OSB mills. Additionally, LP recorded a gain of $10.7 million related to a reduction in product related contingency reserves associated with the National hardboard class action settlement.
During the second quarter of 2011, LP recorded a gain of $1.5 million related to reductions in reforestation liabilities associated with LP's Canadian timber obligations and an increase of $0.9 million in environmental reserves associated with a facility currently held for sale.
During the first quarter of 2011, LP recorded a gain of $0.8 million related to an action against a previous claims inspector associated with LP’s hardboard class action for various states.
During the third quarter of 2010, LP recorded a loss of $2.2 million associated with LP's settlement of a product related anti-trust litigation matter.
During the second quarter of 2010, LP recorded a loss of $0.6 million associated with an assessment in connection with its indefinitely curtailed OSB mills.
NOTE 11 – TRANSACTIONS WITH AFFILIATES
LP has equity investments in AbitibiBowater-LP (a manufacturer of I-joist) and Canfor-LP ( a manufacturer of OSB). LP sells products and raw materials to AbitibiBowater-LP and purchases products for resale from AbitibiBowater-LP and Canfor-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% interest. For the quarters ended September 30, 2011 and 2010, LP sold $1.5 million and $0.4 million of products to AbitibiBowater-LP and purchased $9.6 million and $7.7 million of I-joist from AbitibiBowater-LP. LP also purchased $19.3 million and $21.4 million of OSB from Canfor-LP during the quarters ended September 30, 2011 and 2010. For the nine month periods ended September 30, 2011 and 2010, LP sold $4.4 million and $4.8 million of products to AbitibiBowater-LP and purchased $26.4 million and $31.8 million of I-joist from AbitibiBowater-LP. LP also purchased $65.8 million and $85.8 million of OSB from Canfor-LP during the nine months ended September 30, 2011 and 2010. Included in LP’s Consolidated Balance Sheets at September 30, 2011 and December 31, 2010 are $1.9 million and $1.6 million in accounts receivable from these affiliates and $3.4 million and $2.4 million in accounts payable related to these affiliates.
NOTE 12 – LEGAL AND ENVIRONMENTAL MATTERS
Certain environmental matters and legal proceedings are discussed below.
Environmental Matters
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
13

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.
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.
NOTE 13 – SELECTED SEGMENT DATA
LP operates in three segments: Oriented Strand Board (OSB), Siding, and Engineered Wood Products (EWP). LP’s business units have been aggregated into these three segments based upon the similarity of economic characteristics, customers and distribution methods. LP’s results of operations are summarized below for each of these segments separately as well as for the “other” category which comprises other products that are not individually significant. Segment information was prepared in accordance with the same accounting principles as those described in Note 1 of the Notes to the financial statements included in LP’s Annual Report on Form 10-K for the year ended December 31, 2010.

NOTE 14 – POTENTIAL IMPAIRMENTS
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 September 30, 2011, the undiscounted cash flows for the facilities indefinitely curtailed support the conclusion that no impairment is necessary for those facilities. However, if demand and pricing for the relevant products continues at levels
14

significantly below cycle average demand and pricing, or should LP decide to invest capital in alternative projects, it is possible that impairment charges will be required. See discussion in Note 3 Fair Value Measurements for impairment charges recorded in the periods presented.
LP also reviews from time to time possible dispositions of various assets in light of current and anticipated economic and industry conditions, its strategic plan and other relevant circumstances. Because a determination to dispose of particular assets can require management to make assumptions regarding the transaction structure of the disposition and to estimate the net sales proceeds, which may be less than previous estimates of undiscounted future net cash flows, LP may be required to record impairment charges in connection with decisions to dispose of assets.
NOTE 15 – CONTINGENCY RESERVES
LP maintains reserves for various contingent liabilities as follows:

Dollar amounts in millions | September 30, 2011 |  | December 31, 2010
Environmental reserves | $ | 15.2 |  |  | $ | 14.3 |
Hardboard siding reserves | 6.4 |  |  | 17.8 |
Other reserves | 0.2 |  |  | 0.8 |
Total contingency reserves | 21.8 |  |  | 32.9 |
Current portion of contingency reserves | (4.0 | ) |  | (7.0 | )
Long-term portion of contingency reserves | $ | 17.8 |  |  | $ | 25.9 |

Hardboard Siding Reserves
LP has established reserves relating to certain liabilities associated with a settlement agreement resulting from a nationwide class action lawsuit involving hardboard siding manufactured or sold by corporations acquired by LP in 1999 and installed prior to May 15, 2000 which was approved by the applicable courts in 2000. This settlement is discussed in greater detail in the Notes to the financial statements included in LP’s Annual Report on Form 10-K for the year ended December 31, 2010. LP believes that the reserve balance for this settlement at September 30, 2011 will be adequate to cover future payments to claimants and related administrative costs.
The activity in the portion of LP's loss contingency reserves relating to hardboard siding contingencies for the first nine months of 2011 and 2010 are summarized in the following table.

Dollar amounts in millions | September 30, 2011 |  | September 30, 2010
Beginning balance, December 31, | $ | 17.8 |  |  | $ | 24.2 |
Reversal of reserves | (10.7 | ) |  | — |
Payments made for claims | (0.4 | ) |  | (2.4 | )
Payments made for administrative costs | (0.3 | ) |  | (1.2 | )
Ending balance | $ | 6.4 |  |  | $ | 20.6 |

During the third quarter of 2011, LP decreased its reserves in connection with this settlement due to reductions in claims activity. LP believes that the reserve balance at September 30, 2011 will be adequate to cover future payments to claimants and related administrative costs.
NOTE 16 – DEFINED BENEFIT PENSION PLANS
The following table sets forth the net periodic pension cost for LP’s defined benefit pension plans during the quarter ended September 30, 2011 and 2010. The net periodic pension cost included the following components:

| Quarter Ended September 30, |  | Nine Months Ended September 30,
Dollar amounts in millions | 2011 |  | 2010 |  | 2011 |  | 2010
Service cost | $ | 0.8 |  |  | $ | 0.8 |  |  | $ | 2.4 |  |  | $ | 2.5 |
Interest cost | 4.0 |  |  | 4.2 |  |  | 12.0 |  |  | 13.9 |
Expected return on plan assets | (4.5 | ) |  | (4.8 | ) |  | (13.5 | ) |  | (15.4 | )
Amortization of prior service cost | 0.1 |  |  | 0.1 |  |  | 0.3 |  |  | 0.3 |
Amortization of net loss | 1.1 |  |  | 1.2 |  |  | 3.3 |  |  | 4.0 |
Net periodic pension cost | $ | 1.5 |  |  | $ | 1.5 |  |  | $ | 4.5 |  |  | $ | 5.3 |

During the nine months ended September 30, 2011 and 2010, LP recognized $4.5 million and $5.3 million of pension expense for all of LP’s defined benefit pension plans.
During the nine months ended September 30, 2011, LP made $11.0 million in pension contributions for LP’s defined benefit plans. LP presently anticipates making approximately $0.5 million in additional pension contributions for the plans during the remainder of 2011.
NOTE 17 – 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 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. See Note 21 of the Notes to the financial statements included in LP’s Annual Report on Form 10-K for the year ended December 31, 2010 for further discussion of LP’s guarantees and indemnifications.
During the first nine months of 2011, LP provided a guarantee on behalf of one of its joint ventures to the joint venture bank lender of $3.4 million. Subsequent to the end of the third quarter, LP agreed to contribute $3.0 million to this joint venture and the guarantee amount was reduced to $2.2 million.
Additionally, LP provides 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 third quarter and first nine months of 2011 and 2010 are summarized in the following table:

| Quarter Ended September 30, |  | Nine Months Ended September 30,
Dollar amounts in millions | 2011 |  | 2010 |  | 2011 |  | 2010
Beginning balance | $ | 30.6 |  |  | $ | 30.6 |  |  | $ | 29.5 |  |  | $ | 32.9 |
Accrued to expense | 9.8 |  |  | 0.9 |  |  | 14.7 |  |  | 4.3 |
Payments made | (5.2 | ) |  | (4.0 | ) |  | (9.0 | ) |  | (9.7 | )
Total warranty reserves | 35.2 |  |  | 27.5 |  |  | 35.2 |  |  | 27.5 |
Current portion of warranty reserves | (12.0 | ) |  | (10.0 | ) |  | (12.0 | ) |  | (10.0 | )
Long-term portion of warranty reserves | $ | 23.2 |  |  | $ | 17.5 |  |  | $ | 23.2 |  |  | $ | 17.5 |

During the third quarter of 2011, LP increased the warranty reserves related to discontinued composite decking products by $8.2 million which was a further increase from the $3.8 million recorded in the second quarter of 2011. The additional reserves reflect revised estimates of future claim payments based upon an increase in decking warranty claims and associated costs related to a specific operation and specific time period. LP continues to monitor warranty and other claims associated with these products and believes as of September 30, 2011 that the reserves associated with these matters are adequate. However, it is possible that additional charges may be required in the future.
The current portion of the warranty reserve is included in the caption “Accounts payable and accrued liabilities” and the long-term portion is included in the caption “Other long-term liabilities” on LP’s Condensed Consolidated Balance Sheets.
NOTE 18 - NON-CONTROLLING INTEREST
On June 14, 2011, LP purchased the remaining 25% ownership of LP Brazil from Massisa for a payment of $24.0 million. Subsequent to the purchase, LP incurred $10.0 million of long term export financing debt in connection with the purchase and used a portion of the proceeds to repay interim borrowing incurred to fund a portion of the purchase price.
NOTE 19 - DISCONTINUED OPERATIONS
Over the last several years, LP has adopted and implemented plans to sell selected businesses and assets in order to improve its
15

operating results. For all periods presented, these operations include residual losses of mills divested in past years and associated warranty and other liabilities associated with these operations.
Included in the operating losses of discontinued operations for the third quarter of 2011 is an increase in warranty reserves of $8.2 million associated with previously discontinued composite decking products based upon expected increases in warranty claim activity. In addition to the above mentioned increase, included in operating losses of discontinued operations for the nine months ended September 30, 2011 was an increase or $3.8 million in warranty reserves recorded in the second quarter of 2011.
Included in the operating losses of discontinued operations for the third quarter of 2010 is a settlement of $0.9 million associated with a class action suit related to a previously discontinued product. In addition to the above, included in the operating losses for the nine months ended September 30, 2010 is a settlement with a customer associated with a previously discontinued product of $1.9 million.
NOTE 20 - RECENT AND PROSPECTIVE ACCOUNTING PRONOUNCEMENTS
In June 2011, the Financial Accounting Standards Board ("FASB") amended Accounting Standards Codification ("ASC") 220, “Presentation of Comprehensive Income.” This amendment will require companies to present the components of net income and other comprehensive income either as one continuous statement or as two consecutive statements. It eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity. The amended guidance, which must be applied retroactively, is effective for interim and annual periods beginning after December 15, 2011, with earlier adoption permitted. This Accounting Standards Update ("ASU") impacts presentation only and will have no effect on LP's financial condition, results of operations or cash flows.
In May 2011, the FASB amended ASC 820, "Fair Value Measurement." This amendment is intended to result in convergence between U.S. GAAP and International Financial Reporting Standards (“IFRS”) requirements for measurement of and disclosures about fair value. This guidance clarifies the application of existing fair value measurements and disclosures, and changes certain principles or requirements for fair value measurements and disclosures. The amendment is effective for interim and annual periods beginning after December 15, 2011. Based upon initial assessment, LP does not believe the adoption of this amendment will have a material impact on its consolidated financial statements.

Item 2. | Management's Discussion and Analysis of Financial Condition and Results of Operations

GENERAL
Our products are used primarily in new home construction, repair and remodeling, and manufactured housing. We also market and sell our products in light industrial and commercial construction and we have a modest export business. Our manufacturing facilities are primarily located in the U.S. and Canada, but we also operate two facilities in Chile and a Brazilian facility (the remaining 25% ownership interest of which was acquired during the second quarter of 2011).
To serve our markets, we operate in three segments: Oriented Strand Board (OSB), Siding, and Engineered Wood Products (EWP).
Demand for our products correlates to a significant degree to the level of residential construction activity in North America, which historically has been characterized by significant cyclicality. For the third quarter of 2011, the U.S. Department of Census reported that actual single and multi-family housing starts were 6% higher than for the third quarter of 2010. For the first nine months of 2011, the U.S. Department of Census reported that actual single and multi-family housing starts were 2% lower than for the first nine months of 2010. Building activity is unlikely to improve to “normal” levels until the number of homes available for sale is reduced, foreclosure activity subsides, employment grows and housing prices stabilize further.
OSB is sold as a commodity for which sales prices fluctuate daily based on market factors over which we have little or no control. We cannot predict whether the prices of our products will remain at current levels or increase or decrease in the future. For the third quarter of 2011 and first nine months of 2011, OSB prices, as reported by Random Lengths, were 2% higher and 20% lower than the same periods in 2010.
For additional factors affecting our results, refer to the Management Discussion and Analysis overview contained in our Annual Report on Form 10-K for the year ended December 31, 2010 and to “About Forward-Looking Statements” and “Risk Factors” in this report.
CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ESTIMATES
Presented in Note 1 of the Notes to the financial statements included in LP’s Annual Report on Form 10-K for the year ended December 31, 2010 is a discussion of our significant accounting policies and significant accounting estimates and judgments. Throughout the preparation of the financial statements, we employ significant judgments in the application of accounting principles and methods. These judgments are primarily related to the assumptions used to arrive at various estimates. For the third quarter of 2011, these significant accounting estimates and judgments include:
Legal Contingencies. Our estimates of loss contingencies for legal proceedings are based on various judgments and assumptions regarding the potential resolution or disposition of the underlying claims and associated costs. In making judgments and assumptions regarding legal contingencies for ongoing class action settlements, we consider, among other things, discernible trends in the rate of claims asserted and related damage estimates and information obtained through consultation with statisticians and economists, including statistical analysis of potential outcomes based on experience to date and the experience of third parties who have been subject to product-related claims judged to be comparable. Due to the numerous variables associated with these judgments and assumptions, both the precision and reliability of the resulting estimates of the related loss contingencies are subject to substantial uncertainties. We regularly monitor our estimated exposure to these contingencies and, as additional information becomes known, may change our estimates significantly.
Environmental Contingencies. Our estimates of loss contingencies for environmental matters are based on various judgments and assumptions. These estimates typically reflect judgments and assumptions relating to the probable nature, magnitude and timing of required investigation, remediation and/or monitoring activities and the probable cost of these activities, and in some cases reflect judgments and assumptions relating to the obligation or willingness and ability of third parties to bear a proportionate or allocated share of the cost of these activities, including third parties who purchased assets from us subject to environmental liabilities. We consider the ability of third parties to pay their apportioned cost when developing our estimates. In making these judgments and assumptions related to the development of our loss contingencies, we consider, among other things, the activity to date at particular sites, information obtained through consultation with applicable regulatory authorities and third-party consultants and contractors and our historical experience at other sites that are judged to be comparable. Due to the numerous variables associated with these judgments and assumptions, and the effects of changes in governmental regulation and environmental technologies, both the precision and reliability of the resulting estimates of the related contingencies are subject to substantial uncertainties. We regularly monitor our estimated exposure to environmental loss contingencies and, as additional information becomes known, may change our estimates significantly. At September 30, 2011, we excluded from our estimates approximately $1.3 million of potential environmental liabilities that we estimate will be allocated to third parties pursuant to existing and anticipated future cost sharing arrangements.
Impairment of Long-Lived Assets. We review the long-lived assets held and used by us (primarily property, plant and equipment
17

and timber and timberlands) for impairment when events or changes in circumstances indicate that the carrying amount of assets may not be recoverable. We consider the necessity of undertaking such a review at least quarterly, and also when certain events or changes in circumstances occur. Events and changes in circumstances that may necessitate such a review include, but are not limited to: a significant decrease in the market price of a long-lived asset or group of long-lived assets; a significant adverse change in the extent or manner in which a long-lived asset or group of long-lived assets is being used or in its physical condition; a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset or group of long-lived assets, including an adverse action or assessment by a regulator; an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset or group of long-lived assets; current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or group of long-lived assets; and current expectation that, more likely than not, a long-lived asset or group of long-lived assets will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. Identifying these events and changes in circumstances, and assessing their impact on the appropriate valuation of the affected assets under accounting principles generally accepted in the U.S., requires us to make judgments, assumptions and estimates.
In general, for assets held and used in our operations, impairments are recognized when the carrying amount of the long-lived asset or groups of long-lived assets is not recoverable and exceeds the fair value of the asset or group of assets. The carrying amount of a long-lived asset or groups of long-lived assets is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the assets or group of assets. The key assumptions in estimating these cash flows relate to future production volumes, pricing of commodity or specialty products and future estimates of expenses to be incurred as reflected in our long-range internal planning models. Our assumptions regarding pricing are based upon the average pricing over the commodity cycle (generally five years) due to the inherent volatility of commodity product pricing, and reflect our assessment of information gathered from industry research firms, research reports published by investment analysts and other published forecasts. Our assumptions regarding expenses reflect our expectation that we will continue to reduce production costs to offset inflationary impacts.
When impairment is indicated for assets held and used in our operations, the book values of the affected assets are written down to their estimated fair value, which is generally based upon discounted future cash flows associated with the affected assets. When impairment is indicated for assets to be disposed of, the book values of the affected assets are written down to their estimated fair value, less estimated selling costs. Consequently, a determination to dispose of particular assets can require us to estimate the net sales proceeds expected to be realized upon such disposition, which may be less than the estimated undiscounted future net cash flows associated with such assets prior to such determination, and thus require an impairment charge. In situations where we have experience in selling assets of a similar nature, we may estimate net sales proceeds on the basis of that experience. In other situations, we hire independent appraisers to estimate net sales proceeds.
Due to the numerous variables associated with our judgments and assumptions relating to the valuation of assets in these circumstances, and the effects of changes in circumstances affecting these valuations, both the precision and reliability of the resulting estimates of the related impairment charges are subject to substantial uncertainties and, as additional information becomes known, we may change our estimates significantly.
Income Taxes. The determination of the provision for income taxes, and the resulting current and deferred tax assets and liabilities, involves significant management judgment, and is based upon information and estimates available to management at the time of such determination. The final income tax liability to any taxing jurisdiction with respect to any calendar year will ultimately be determined long after our financial statements have been published for that year. We maintain reserves for known estimated tax exposures in federal, state and international jurisdictions; however, actual results may differ materially from our estimates.
Judgment is also applied in determining whether deferred tax assets will be realized in full or in part. When we consider it to be more likely than not that all or some portion of a deferred tax asset will not be realized, a valuation allowance is established for the amount of the deferred tax asset that is estimated not to be realizable. As of September 30, 2011, we had established valuation allowances against certain deferred tax assets, primarily related to state and foreign carryovers of net operating losses, credits and capital losses. We have not established valuation allowances against other deferred tax assets based upon tax strategies implemented or deferred tax liabilities which we anticipate to reverse within the carry forward period. Accordingly, changes in facts or circumstances affecting the likelihood of realizing a deferred tax asset could result in the need to record additional valuation allowances.
Auction Rate Securities: Our auction-rate securities represent interests in collateralized debt obligations, a portion of which are supported by pools of residential and commercial mortgages, bank trust preferred notes and other securities. Historically, liquidity for these auction-rate securities was typically provided by an auction process that reset the applicable interest rate at pre-determined intervals, usually every 7, 28, 35 or 90 days. As of September 30, 2011, auction-rate securities that we hold had experienced multiple failed auctions as the amount of securities for sale exceeded the amount of purchase orders. Consequently, we have classified $0.5 million ($23.4 million, par value) of auction-rate securities as long-term available-for-sale securities.

Our estimates of the valuation of our current holdings of auction rate securities are based upon our evaluation of the structure of our auction rate securities and current market estimates of fair value, including fair value estimates from the issuing banks and indicative pricing from other parties. We review several factors to determine whether a loss is other-than-temporary. These factors include but are not limited to: (i) the length of time a security is in an unrealized loss position, (ii) the extent to which fair value is less than cost, (iii) the financial condition and near term prospects of the issuer, and (iv) our intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. Due to the numerous variables associated with these judgments, both the precision and reliability of the resulting estimates of the related valuation allowance are subject to substantial uncertainties. We regularly monitor our estimated exposure to these investments and, as additional information becomes known, may change our estimates significantly.
Pension Plans. Most of our U.S. employees and many of our Canadian employees participate in defined benefit pension plans sponsored by LP. We account for the consequences of our sponsorship of these plans in accordance with accounting principles generally accepted in the U.S., which require us to make actuarial assumptions that are used to calculate the related assets, liabilities and expenses recorded in our financial statements. While we believe we have a reasonable basis for these assumptions, which include assumptions regarding long-term rates of return on plan assets, life expectancies, rates of increase in salary levels, rates at which future values should be discounted to determine present values and other matters, the amounts of our pension related assets, liabilities and expenses recorded in our financial statements would differ if we used other assumptions.
Workers’ Compensation. We are self insured for most of our U.S. employees’ workers compensation claims. We account for these plans in accordance with accounting principles generally accepted in the U.S., which require us to make actuarial assumptions that are used to calculate the related assets, liabilities and expenses recorded in our financial statements. While we believe we have a reasonable basis for these assumptions, which include assumptions regarding rates at which future values should be discounted to determine present values, expected future health care costs and other matters, the amounts of our liabilities and related expenses recorded in our financial statements would differ if we used other assumptions.
Warranty Obligations. Customers are provided with a limited warranty against certain defects associated with our products for periods of up to fifty years. We estimate the costs to be incurred under these warranties and record a liability in the amount of such costs at the time product revenue is recognized. Factors that affect our warranty liability include the historical and anticipated rates of warranty claims and the cost of resolving such. We periodically assess the adequacy of our recorded warranty liability for each product and adjust the amounts as necessary. While we believe we have a reasonable basis for these assumptions, actual warranty costs in the future could differ from our estimates.
NON-GAAP FINANCIAL MEASURES
In evaluating our business, we utilize several non-GAAP financial measures. A non-GAAP financial measure is generally defined by the SEC as one that purports to measure historical or future financial performance, financial position or cash flows, but excludes or includes amounts that would not be so excluded or included under applicable GAAP guidance. In this report on Form 10-Q, we disclose earnings (loss) from continuing operations before interest expense, taxes, depreciation and amortization (“EBITDA from continuing operations”) which is a non-GAAP financial measure. Additionally, we disclose adjusted EBITDA from continuing operations which further adjusts EBITDA from continuing operations to exclude stock based compensation expense, (gain) loss on sales or impairment of long lived assets, other operating charges and credits, other than temporary investment impairment, (gain) loss on early debt extinguishment and investment income. Neither EBITDA from continuing operations nor adjusted EBITDA from continuing operations is a substitute for the GAAP measures of net income or operating cash flows or for any other GAAP measures of operating performance or liquidity.
We have included EBITDA from continuing operations and adjusted EBITDA from continuing operations in this report on Form 10-Q because we use them as important supplemental measures of our performance and believe that they are frequently used by securities analysts, investors and other interested persons in the evaluation of companies in our industry, some of which present EBITDA when reporting their results. We use EBITDA from continuing operations and adjusted EBITDA from continuing operations to evaluate our performance as compared to other companies in our industry that have different financing and capital structures and/or tax rates. It should be noted that companies calculate EBITDA and adjusted EBITDA differently and, therefore, our EBITDA and adjusted EBITDA measures may not be comparable to EBITDA and adjusted EBITDA reported by other companies. Our EBITDA and adjusted EBITDA measures have material limitations as performance measures because they exclude interest expense, income tax (benefit) expense and depreciation and amortization which are necessary to operate our business or which we otherwise incurred or experienced in connection with the operation of our business.
The following table represents significant items by operating segment and reconciles income (loss) from continuing operations to Adjusted EBITDA from continuing operations:

RESULTS OF OPERATIONS
(Dollar amounts in millions, except per share amounts)
Our net loss attributable to LP for the third quarter of 2011 was $65.6 million, or $0.49 per diluted share, on sales of $350.6 million, compared to a net loss attributable to LP for the third quarter of 2010 of $32.0 million, or $0.24 per diluted share, on sales of $322.8 million. For the third quarter of 2011, loss from continuing operations attributed to LP was $59.3 million, or $0.44 per diluted share, compared to $31.2 million, or $0.23 per diluted share, for the third quarter of 2010.
Our net loss attributable to LP for the first nine months of 2011 was $124.1 million , or $0.94 per diluted share, on sales of $1.0 billion, compared to net loss attributable to LP for the first nine months of 2010 of $32.2 million, or $0.25 per diluted share, on sales of $1.1 billion. For the first nine months of 2011, loss from continuing operations attributed to LP was $115.3 million million, or $0.87 per diluted share, compared to $30.0 million, or $0.23 per diluted share, for the first nine months of 2010.
Our results of operations for each of our segments are discussed below as well as for the “other” category, which comprises products that are not individually significant.
OSB
Our OSB segment manufactures and distributes commodity and value-added OSB structural panels.
Segment sales, operating losses, and adjusted EBITDA from continuing operations for this segment are as follows:

| Quarter Ended September 30, |  | Nine Months Ended September 30,
| 2011 |  | 2010 |  | Change |  | 2011 |  | 2010 |  | Change
Net sales | $ | 138.8 |  |  | $ | 140.1 |  |  | (1 | )% |  | $ | 411.4 |  |  | $ | 475.5 |  |  | (13 | )%
Operating profits (losses) | (16.0 | ) |  | (5.0 | ) |  | 220 | % |  | (48.0 | ) |  | 38.4 |  |  | (225 | )%
Adjusted EBITDA from continuing operations | (6.7 | ) |  | 4.6 |  |  | (246 | )% |  | (19.6 | ) |  | 67.1 |  |  | (129 | )%

Percent changes in average sales prices and unit shipments for the quarter and nine months ended September 30, 2011 compared to the quarter and nine months ended September 30, 2010 are as follows:

| Quarter Ended September 30, 2011 versus 2010 |  | Nine Months Ended September 30, 2011 versus 2010
| Average Net Selling Price |  | Unit Shipments |  | Average Net Selling Price |  | Unit Shipments
OSB | (7 | )% |  | 5 | % |  | (19 | )% |  | 5 | %

For both the quarter and nine months ended September 30, 2011, OSB prices decreased as compared to the corresponding periods in 2010. The decrease in OSB prices was likely due to weakening of the relationship between supply and demand based upon currently operating facilities across the industry. The decrease in selling price unfavorably impacted operating results and adjusted EBITDA from continuing operations by approximately $9 million for the quarter and $91 million for the nine month period ended as compared to the corresponding periods of 2010. Sales volumes increased for both periods as we continue to move into industrial applications as well as increasing our exports. To continue to balance supply and demand, during the quarter, we announced the indefinite curtailment of our Dawson Creek, British Columbia, Canada OSB mill. Including this mill, the total indefinitely curtailed OSB mills is three as of September 30, 2011.
Compared to the third quarter and first nine months of 2010, the primary factor for increased operating losses was the decrease in commodity OSB sales prices.
SIDING
Our siding segment produces and markets wood-based siding and related accessories, together with commodity OSB products from one mill.
Segment sales, operating profits and adjusted EBITDA from continuing operations for this segment are as follows:

| Quarter Ended September 30, |  | Nine Months ended September 30,

For the third quarter and first nine months of 2011 compared to the corresponding period in 2010, sales volumes increased in our SmartSide siding line due to continued penetration in several key focus markets including retail (primarily driven by increases in the repair and remodel markets) and sheds. Sales prices in our SmartSide siding product line for both the quarter and nine month periods ended September 30, 2011 as compared to the corresponding periods of 2010 increased due to sales price increase announced in the first quarter of 2011.
For both the third quarter and first nine months of 2011 compared to the same periods in the prior year, sales volumes declined in our Canexel siding lines due to some weakening in the Canadian housing market and lower shipments to Europe. Sales prices increased in the third quarter and first nine months of 2011 as compared to the corresponding periods of last year due to the impact of the strengthening Canadian dollar as a majority of these sales are made in Canada and a movement to a richer product mix.
For both the third quarter and first nine months of 2011 as compared to the same periods in the prior year, sales prices declined for our commodity OSB products as discussed in the OSB segment above. The decrease in selling price unfavorably impacted operating results and adjusted EBITDA from continuing operations by approximately $0.5 million for the quarter and $5.2 million for the nine month period as compared to the corresponding periods of 2010.
Overall, the change in operating results for our siding segment for the third quarter and nine months ended September 30, 2011 compared to the same periods of 2010 was primarily due to reduced OSB pricing and raw material pricing increases that were partially offset by higher sales prices in both our SmartSide and Canexel product lines.
ENGINEERED WOOD PRODUCTS
Our engineered wood products (EWP) segment manufactures and distributes laminated veneer lumber (LVL), I-Joists, laminated strand lumber (LSL) and other related products. This segment also includes the sale of I-Joist and LVL products produced by AbitibiBowater-LP or under a sales arrangement with a third party distributor.
Segment sales, operating losses and adjusted EBITDA from continuing operations for this segment are as follows:

| Quarter Ended September 30, |  | Nine months ended September 30,
| 2011 |  | 2010 |  | Change |  | 2011 |  | 2010 |  | Change
Net sales | $ | 54.9 |  |  | $ | 38.0 |  |  | 44 | % |  | $ | 156.9 |  |  | $ | 142.7 |  |  | 10 | %
Operating losses | (3.2 | ) |  | (4.9 | ) |  | 35 | % |  | (11.9 | ) |  | (15.9 | ) |  | 25 | %
Adjusted EBITDA from continuing operations | (0.2 | ) |  | (2.5 | ) |  | 92 | % |  | (1.4 | ) |  | (6.1 | ) |  | 77 | %

Sales in this segment by product line are as follows:

| Quarter Ended September 30, |  | Nine Months Ended September 30,
| 2011 |  | 2010 |  | Change |  | 2011 |  | 2010 |  | Change

Percent changes in average sales prices and unit shipments for the quarter and nine month periods ended September 30, 2011 compared to the quarter and nine months ended September 30, 2010 are as follows:

| Quarter Ended September 30, 2011 versus 2010 |  | Nine Months Ended September 30, 2011 versus 2010
| Average Net Selling Price |  | Unit Shipments |  | Average Net Selling Price |  | Unit Shipments

I-Joist | (3 | )% |  | 26 | % |  | 4 | % |  | (19 | )%

During the third quarter of 2011 compared to the same period of 2010, we saw increases in sales volumes in both LVL/LSL and I-Joist primarily due to lower volumes in the third quarter of 2010 as customers adjusted inventory levels. Also we had an increase in our export sales. Sales price for the quarter declined due to changes in mix in both product lines with individual product pricing remaining relatively flat. For the nine month period ended September 30, 2011 compared to the same period in 2010, unit shipments increased in LVL/LSL based upon significant increases in exports. For the nine month period ended September 30, 2011 compared to the same period in 2010, we realized a decline in I-joist volumes due to lower U.S. and Canadian demand which more than offset our increases in export sales. Our focus in the EWP segment continues to be on reductions in conversion costs, better geographic manufacturing and distribution, and maintaining key customer relationships.
25

Included in this segment is a plywood operation, which primarily produces plywood as a by-product from the LVL production process.
For the third quarter and first nine months of 2011 compared to the corresponding periods of 2010, the results of operations for EWP were improved due to continued improvements in our LSL facility as well as higher sales volumes of LVL/LSL.
OTHER PRODUCTS
Our other products category includes a moulding business, South American operations, export sales and a joint venture that produces and sells cellulose insulation. This category also includes remaining timber and timberlands and other minor products, services and operations closed prior to January 1, 2002.
Segment sales, operating profits and adjusted EBITDA from continuing operations for this category are as follows:

| Quarter Ended September 30, |  | Nine Months Ended September 30,
| 2011 |  | 2010 |  | Change |  | 2011 |  | 2010 |  | Change
Net sales | $ | 45.8 |  |  | $ | 41.2 |  |  | 11 | % |  | $ | 141.6 |  |  | $ | 130.1 |  |  | 9 | %
Operating profits (losses) | (0.9 | ) |  | 0.7 |  |  | (229 | )% |  | 4.2 |  |  | 4.6 |  |  | (9 | )%
Adjusted EBITDA from continuing operations | 2.2 |  |  | 3.5 |  |  | (37 | )% |  | 13.7 |  |  | 13.0 |  |  | 5 | %

Sales in this segment by operation are as follows:

| Quarter Ended September 30, |  | Nine Months Ended September 30,
| 2011 |  | 2010 |  | Change |  | 2011 |  | 2010 |  | Change

For the third quarter of 2011 compared to the corresponding period of 2010, sales in our moulding business were higher due to increased activity in the retail markets. In the first nine months of 2011 compared to the corresponding period of 2010, sales in our moulding operation were lower due to initial purchases by a new customer in the first nine months of 2010. Sales in both our Chilean and Brazil operations continue to increase as penetrate local and export markets.
Overall, operating results associated with these activities were positively impacted by improvements in our Chilean operations which were more than offset by reduced operating results in moulding and our U.S. Greenfiber joint venture.
GENERAL CORPORATE AND OTHER EXPENSE, NET
For the third quarter and first nine months of 2011 compared to the corresponding periods of 2010, general corporate expenses decreased 11 percent and 10 percent and overall selling and administrative expenses decreased by 4 percent and 5 percent. General corporate and other expenses primarily consist of corporate overhead such as wages and benefits for corporate and sales personnel, professional fees, insurance and other expenses. The decrease in general corporate expenses as well as overall selling and administrative is primarily related to changes in the management incentive program between periods as well as continued cost containment.
INTEREST EXPENSE AND INVESTMENT INCOME
Components of interest expense, net of investment income, are as follows:

INCOME TAXES
For the third quarter and first nine months of of 2011, we recorded an income tax benefit on continuing operations of 26% and 24% as compared to 35% and 32% in the comparable periods of 2010. The primary difference between the U.S. statutory rate of 35% and the effective rate applied to continuing operations for the first nine months of 2011 relates to state income taxes, the effect of foreign tax rates and increases in valuation allowances due to net operating loss carryforwards in various jurisdictions. For the nine months of 2010, the primary differences between the U.S. statutory rate of 35% and the effective rate applicable to our continuing operations relate to state income taxes, the effect of foreign tax rates and a discrete adjustment for state income taxes.
DEFINED BENEFIT PENSION PLANS
We maintain several qualified and non-qualified defined benefit pension plans in the U.S. and Canada that cover a substantial portion of our employees. See Note 13 of the Notes to financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2010 for further information on our plans. We estimate that our net periodic pension cost for 2011 will be approximately $5.7 million. If a curtailment or settlement occurs in 2011, this estimate may change significantly. We estimate that we will contribute approximately $10 to $12 million to our defined benefit pension plans in 2011. At December 31, 2010, we had $115.1 million of net actuarial loss and $1.0 million of prior service cost included in accumulated other comprehensive loss. Of these amounts, we expect to recognize a net actuarial loss of $3.5 million as a component of net periodic pension cost in 2011, which will account for approximately 62% of our estimated 2011 net periodic pension cost. Based upon the continued decline in the long term discount rates, we anticipate a significant increase in our long term pension obligation as of the next measurement date. This could potentially negatively impact our 2012 net periodic pension costs and possibly impact our funding requirements in 2012.
LEGAL AND ENVIRONMENTAL MATTERS
For a discussion of legal and environmental matters involving us and the potential impact thereof on our financial position, results of operations and cash flows, see Items 3, 7 and 8 in our Annual Report on Form 10-K for the year ended December 31, 2010, Note 18 to the Notes to the financial statements contained therein.
HARDBOARD SIDING LITIGATION UPDATE
The following update should be read in conjunction with the discussion of our hardboard siding litigation set forth in Note 18 of the Notes to financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2010.
Cumulative statistics under hardboard siding settlements are as follows:

| September 30, 2011
Completed claims received | 87,200 |
Claims dismissed | 14,700 |
Claims settled | 72,500 |

27

The average payment amount for settled claims as of September 30, 2011 was $960. Dismissal of claims is typically the result of claims for product not produced by LP or predecessor companies or claims that lack sufficient information or documentation after repeated efforts to correct those deficiencies.
LIQUIDITY AND CAPITAL RESOURCES
OVERVIEW
Our principal sources of liquidity are existing cash and investment balances, cash generated by our operations and our ability to borrow under credit facilities. We may also from time to time issue and sell equity, debt or hybrid securities or engage in other capital market transactions.
Our principal uses of liquidity are paying the costs and expenses associated with our operations, servicing outstanding indebtedness and making capital expenditures. We may also from time to time prepay or repurchase outstanding indebtedness, repurchase shares of our common stock and acquire assets or businesses that are complementary to our operations. Any such repurchases may be commenced, suspended, discontinued or resumed, and the method or methods of effecting any such repurchases may be changed, at any time or from time to time without prior notice.
We expect to be able to meet the future cash requirements of our existing businesses through cash expected to be generated from operations, existing cash and investment balances, existing credit facilities and other capital resources. The following discussion provides further details of our liquidity and capital resources.
OPERATING ACTIVITIES
During the first nine months of 2011, we used $33.8 million of cash from operating activities compared to cash provided of $45.0 million in the first nine months of 2010. The increase in cash used by operating activities in the first nine months of 2011 was primarily related to the increased losses as well as the receipt of $34.7 million tax refund in the first nine months of 2010 which did not occur at this same level in 2011.
During the first nine months of 2011, our accounts receivable declined due to lower sales volume across all product lines as well as lower OSB pricing. No substantial change in credit terms or number of days outstanding occurred. Inventory increased based on our requirements to increase log inventory due to the inability to harvest logs during the spring break up. Accounts payable increased slightly.
INVESTING ACTIVITIES
During the first nine months of 2011, cash provided from investing activities was approximately $18.9 million. Capital expenditures in the first six months of 2011 were $13.4 million. Additionally, we contributed $4.6 million to our joint ventures for working capital requirements and received $1.2 million in the sale of assets. We received $19.1 million of proceeds from the sale of investments. We also reduced our restricted cash under letters of credit or credit facility requirements by $16.6 million in connection with the renegotiation of our Chilean loan. Included in “Accounts payable” is $0.4 million related to capital expenditures that had not yet been paid as of September 30, 2011.
During the first nine months of 2010, cash provided from investing activities was approximately $116.3 million. Capital expenditures in the first nine months of 2010 were $11.5 million. Additionally, we received $6.1 million from our joint ventures and $1.5 million in the sale of assets. We received $115.1 million in principal payments on our notes receivable from asset sales. Restricted cash was reduced by $5.1 million. Included in “Accounts payable” was $1.2 million related to capital expenditures that had not yet been paid as of September 30, 2010.
Capital expenditures in 2011 are expected not to exceed $25 million related to projects critical for continuing operations.
FINANCING ACTIVITIES
During the first nine months of 2011, we redeemed the non-controlling interest associated with the 25% ownership of our Brazilian OSB operation for $24.0 million. In connection with this redemption, we borrowed $4.5 million under a short term Chilean working capital loan in the second quarter of 2011 which was repaid in the third quarter of 2011 from a portion of the proceeds of a $10.0 million loan under a Brazilian export financing facility established as part of the redemeption. As part of our on-going cost reduction activities, we renegotiated our Chilean loan which required us to pay a financing fee of $1.0 million allowing us to release our restricted cash associated with letters of credit supporting Chilean borrowings and lower the interest rate on this loan.
During the first nine months of 2010, we repaid $113.4 million of our limited recourse notes payable and $60.3 million of our 8.875% Senior Notes at maturity in August of 2010.
CREDIT AGREEMENTS
We have a credit facility which provides for a committed asset-based borrowing capacity of up to $100 million, with a $60
28

million sublimit for U.S. letters of credit and a $10 million sublimit for Canadian letters of credit. The credit facility is scheduled to end in September of 2012.
The availability of credit under the credit facility is subject to a borrowing base, which is calculated based upon certain percentages of accounts receivable and inventory and at any given time may limit the amount of borrowings and letters of credit otherwise available under the facility. In addition, the credit facility contains a covenant requiring us to maintain a fixed charge coverage ratio of at least 1.1 to 1.0 at any time that our unused borrowing base capacity after adjustment to exclude certain past due trade payables falls below $15 million. This covenant effectively precludes us from using all or a portion of the last $15 million of our unused borrowing base capacity, if, before or immediately after such use, we would not satisfy the minimum fixed charge coverage ratio. At September 30, 2011, we had $75.4 million of unused borrowing base capacity under the credit facility. The credit facility allows us to pledge, as security for our reimbursement obligations in respect of letters of credit issued under the facility, cash collateral in an amount not less than 105% of the of the stated amount of such letters of credit. The above-described preclusion to our utilization of $15 million of the capacity otherwise available under the facility does not apply to such cash collateralized letters of credit. At September 30, 2011, we had no borrowings outstanding under the facility. Outstanding under this facility at September 30, 2011 were $11.1 million in letters of credit which were collateralized by $12.5 million of cash. Based upon our available cash balances, we do not currently anticipate using this facility except to obtain and maintain letters of credit. Additionally, we expect that our fixed charge coverage ratio may fall below 1.1 to 1.0 from time to time during 2011, and, accordingly we will be subject to the limitation on our ability to fully utilize our adjusted borrowing base capacity as described above during such time. As a result, our ability to obtain and maintain non-cash collateralized letters of credit under this facility may become constrained to an amount that does not exceed the excess of our adjusted borrowing base over $15 million.
Subject to certain exceptions, obligations under the credit facility are secured by, among other things, a first-priority lien on our present and future receivables, inventory and certain general intangibles, and by a second-priority lien on substantially all of our domestic property, plant and equipment, and are guaranteed by certain of our subsidiaries.
The credit facility contains customary covenants applicable to us and our subsidiaries, other than certain unrestricted subsidiaries, including certain financial covenants as well as restrictions on, among other things, our ability to: incur debt; incur liens; declare or make distributions to our stockholders; make loans and investments; repay debt; enter into mergers, acquisitions and other business combinations; form or acquire subsidiaries; amend or modify our governing documents; enter into hedging arrangements; engage in other businesses other than our business as currently conducted; and enter into transactions with affiliates. The credit facility also contains customary events of default, the occurrence of which could result in the acceleration of our obligation to repay the indebtedness outstanding thereunder.
Subsequent to September 30, 2011, we entered into the fourth amendment of this agreement which (1) extends the maturity of the revolving loan facility evidenced by the Revolving Loan Agreement from September 10, 2012 to October 14, 2016, (2) decreases the interest rate payable for certain types of loans, (3) permits LP to include in its borrowing base certain vendor managed inventory that was previously excluded, (4) increases LP's flexibility to incur and prepay certain debt and (5) provides that the credit facility lenders' second priority liens on certain assets of LP and its subsidiaries that secure certain indebtedness of LP and its subsidiaries to other parties on a first priority basis will be automatically released in connection with the repayment of such other indebtedness.
Obligations under the indenture governing our Senior Secured Notes due 2017 are, in general, secured by a first-priority lien on the collateral that secures obligations under the credit facility on a second-priority basis, and by a second-priority lien on the collateral that secures obligations under the credit facility on a first-priority basis, subject to the terms of an intercreditor agreement, and are guaranteed by the subsidiaries that guarantee obligations under the credit facility.
The indenture contains customary covenants applicable to us and our subsidiaries, other than certain unrestricted subsidiaries, including restrictions on actions and activities that are restricted under the credit facility. The indenture also contains customary events of defaults, the occurrence of which could result in acceleration of our obligations to repay the indebtedness outstanding thereunder.
OTHER LIQUIDITY MATTERS
As of September 30, 2011, we had $0.5 million ($23.4 million, par value) of principal invested in auction rate securities (ARS). The ARS held by us are securities with long-term nominal maturities for which the interest rates were historically reset through a Dutch auction each month.
We review our marketable securities routinely for other-than-temporary impairment. The primary factors LP uses to determine if an impairment charge must be recorded because a decline in value of the security is other than temporary include (i) whether the fair value of the investment is significantly below its cost basis, (ii) the financial condition of the issuer of the security (including its credit rating), (iii) the length of time that the cost of the security has exceeded its fair value and (iv) LP’s intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in market value.
29

If uncertainties in the credit and capital markets continue, these markets deteriorate further or we experience any ratings downgrades on any investments in our portfolio (including on ARS), we may incur additional impairments to our investment portfolio, which could negatively affect our financial condition, results of operations and cash flow.
POTENTIAL IMPAIRMENTS
We continue to review several mills and investments for potential impairments. Management currently believes we have adequate support for the carrying value of each of these assets based upon the anticipated cash flows that result from our estimates of future demand, pricing and production costs assuming certain levels of planned capital expenditures. As of September 30, 2011, the undiscounted cash flows for the facilities indefinitely curtailed support the conclusion that no impairment is necessary for those facilities. However, should the markets for our products continue to remain at levels significantly below cycle average pricing or should we decide to invest capital in alternative projects, it is possible that we will be required to record further impairment charges.
During the third quarter of 2011, we determined that an impairment review was required of our LSL facility located in Houlton, Maine due to continued operating losses which were driven by the significant reductions in current and forecasted housing starts. This facility is included within our EWP segment. As a result of this review, LP recognized a pre-tax, non-cash impairment charge of $62.0 million which was recorded in the third quarter of 2011.
We also review from time to time possible dispositions of various assets in light of current and anticipated economic and industry conditions, our strategic plan and other relevant factors. Because a determination to dispose of particular assets can require management to make assumptions regarding the transaction structure of the disposition and to estimate the net sales proceeds, which may be less than previous estimates of undiscounted future net cash flows, we may be required to record impairment charges in connection with decisions to dispose of assets.
30

Item 3. | Quantitative and Qualitative Disclosures about Market Risk

A portion of our outstanding debt bears interest at variable rates and accordingly is sensitive to changes in interest rates. Interest rate changes would result in gains or losses in the market value of our debt portfolio due to differences in market interest rates and the rates at the inception of the debt agreements. Offsetting the variable rate debt are variable rate notes receivable from asset sales. Based upon the balances of the variable rate notes receivable from asset sales and the variable rate debt at September 30, 2011, a 100 basis point interest change would impact pre-tax net income and cash flows by $0.4 million annually.
Our international operations have exposure to foreign currency rate risks, primarily due to fluctuations in the Canadian dollar, Brazilian real and the Chilean peso. Although we have in the past entered into foreign exchange contracts associated with certain of our indebtedness and may continue to enter into foreign exchange contracts associated with major equipment purchases to manage a portion of the foreign currency rate risk, we historically have not entered into material currency rate hedges with respect to our exposure from operations, although we may do so in the future.
Some of our products are sold as commodities and therefore sales prices fluctuate daily based on market factors over which we have little or no control. The most significant commodity product we sell is OSB. Based upon an assumed annual production capacity (including our joint venture operation) of 5.0 billion square feet ( 3/8" basis) or 4.3 billion square feet ( 7/16" basis), a $1 change in the annual average price on 7/16" basis would change annual pre-tax profits by approximately $4.3 million. Because of the decline in the housing market and related indefinitely curtailed facilities in our OSB business, we expect that our near-term volumes will be significantly below our capacity.
We historically have not entered into material commodity futures and swaps, although we may do so in the future.

Item 4. | Controls and Procedures

Evaluation of Disclosure Controls and Procedures
Our Chief Executive Officer and Chief Financial Officer have carried out, as of September 30, 2011, with the participation of LP’s management, an evaluation of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act (the “Act”). Based upon this evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that LP’s disclosure controls and procedures are effective to provide reasonable assurance that material information required to be disclosed by us in reports we file under the Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that information required to be disclosed by us in the reports we file or submit under the Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
There were no changes in our internal control over financial reporting that occurred during our most recently completed fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II -OTHER INFORMATION

Item 1. | Legal Proceedings.

The description of certain legal and environmental matters involving LP set forth in Part I of this report under “Note 15 – Contingency Reserves” is incorporated herein by reference.

Item 1A. | Risk Factors.

You should be aware that the occurrence of any of the events described in this Risk Factors section and elsewhere in this report or in any other of our filings with the SEC could have a material adverse effect on our business, financial position, results of operations and cash flows. In evaluating us, you should consider carefully, among other things, the risks described below and the matters described in “About Forward-Looking Statements.”
Cyclical industry conditions and commodity pricing have and may continue to adversely affect our financial condition and results of operations. Our operating results reflect the general cyclical pattern of the building products industry. Demand for our products correlates to a significant degree to the level of residential construction activity in North America, which historically has been characterized by significant cyclicality. This cyclicality is influenced by a number of factors, including the supply of new and existing homes on the market, of which existing homes are currently at above average levels, the level of unemployment, which has been increasing in recent periods, longer-term interest rates, which in recent years have been at relatively low levels, the availability of mortgage financing, which has recently declined, and mortgage foreclosure rates, which are higher than normal. A significant increase in longer-term interest rates, a prolonged decline in the availability of mortgage financing, or the occurrence of other events that reduce levels of residential construction activity could have a material adverse effect on our financial condition, results of operations and cash flows. Our primary product, OSB, and a significant portion of our raw materials are globally traded commodity products. In addition, our products are subject to competition from manufacturers worldwide. Historical prices for our products have been volatile, and we, like other participants in the building products industry, have limited influence over the timing and extent of price changes for our products. Product pricing is significantly affected by the relationship between supply and demand in the building products industry. Product supply is influenced primarily by fluctuations in available manufacturing capacity. Demand is affected by the state of the economy in general and a variety of other factors. The level of new residential construction activity and home repair and remodeling activity primarily affects the demand for our building products. Demand is also subject to fluctuations due to changes in economic conditions, interest rates, population growth, weather conditions and other factors. We are not able to predict with certainty market conditions and selling prices for our products. In this competitive environment with so many variables for which we do not control, we cannot assure you that prices for our products will not decline from current levels. A prolonged and severe weakness in the markets for one or more of our principal products, particularly OSB, could seriously harm our financial condition and results of operations and our ability to satisfy our cash requirements, including the payment of interest and principal on our debt.
We have a high degree of product concentration. OSB accounted for about 44% of our North American sales in the first nine months of 2011 and 49% of our sales in the first nine months of 2010 and we expect OSB sales to continue to account for a substantial portion of our revenues and profits in the future. Concentration of our business in the OSB market further increases our sensitivity to commodity pricing and price volatility. In this competitive environment with so many variables for which we do not control, we cannot assure you that pricing for OSB or our other products will not decline from current levels.
Intense competition in the building products industry could prevent us from increasing or sustaining our net sales and profitability. The markets for our products are highly competitive. Our competitors range from very large, fully integrated forest and building products firms to smaller firms that may manufacture only one or a few types of products. We also compete less directly with firms that manufacture substitutes for wood building products. Many of our competitors have greater financial and other resources than we do, and certain of the mills operated by our competitors may be lower-cost producers than the mills operated by us.
Our results of operations may be harmed by potential shortages of raw materials and increases in raw material costs. The most significant raw material used in our operations is wood fiber. For the year ended December 31, 2010, we obtained about 73% of our wood fiber requirements in the open market. Wood fiber is subject to commodity pricing, which fluctuates on the basis of market factors over which we have no control. In addition, the cost of various types of wood fiber that we purchase in the market has at times fluctuated greatly because of governmental, economic or industry conditions, and may be affected by increased demand resulting from initiatives to increase the use of biomass materials in the production of heat, power, biobased products and biofuels. In addition to wood fiber, we also use a significant quantity of various resins in our manufacturing processes. Resin product costs are influenced by changes in the prices or availability of raw materials used to produce resins, primarily petroleum products, as well as demand for and availability of resin products. Selling prices of our products have not
33

always increased in response to raw material cost increases. We are unable to determine to what extent, if any, we will be able to pass any future raw material cost increases through to our customers through product price increases. Our inability to pass increased costs through to our customers could have a material adverse effect on our financial condition, results of operations and cash flows.
Many of the Canadian forestlands also are subject to the constitutionally protected treaty or common-law rights of the aboriginal peoples of Canada. Most of British Columbia is not covered by treaties and, as a result, the claims of British Columbia’s aboriginal peoples relating to forest resources are largely unresolved, although many aboriginal groups are actively engaged in treaty discussions with the governments of British Columbia and Canada. Final or interim resolution of claims brought by aboriginal groups are expected to result in additional restrictions on the sale or harvest of timber and may increase operating costs and affect timber supply and prices in Canada. It is possible that, over the long term, such claims could have an adverse effect on our business, financial condition and results of operations. In addition, there is proposed legislation in Quebec which could be enacted as early as 2013 which could materially impact our ability to harvest and therefore the valuation of our associated timber licenses in Quebec.
We depend on our senior management team and other key employees, and significant attrition within our management team could adversely affect our business. Our success depends in part on our ability to attract, retain, and motivate senior management and other key employees. Achieving this objective may be difficult due to cost reduction activities, and the effectiveness of our compensation programs. Competition for qualified personnel can be very intense. We must continue to recruit, retain, and motivate senior management and other key employees sufficient to maintain our current business and support our future projects. Cost-cutting measures that have reduced compensation make us vulnerable to attrition among our current senior management team and other key employees, and may make it difficult for us to hire additional senior managers and other key employees. A loss of any such personnel, or the inability to recruit and retain qualified personnel in the future, could have an adverse effect on our business, financial condition, and results of operations.
Our operations require substantial capital. Capital expenditures for expansion or replacement of existing facilities or equipment or to comply with future changes in environmental laws and regulations may be substantial. Although we maintain our production equipment with regular periodic and scheduled maintenance, we cannot assure you that key pieces of equipment in our various production processes will not need to be repaired or replaced or that we will not incur significant additional costs associated with environmental compliance. The costs of repairing or replacing such equipment and the associated downtime of the affected production line could have a material adverse effect on our financial condition, results of operations and cash flow. If for any reason we are unable to provide for our operating needs, capital expenditures and other cash requirements on economic terms, we could experience a material adverse effect on our business, financial condition, results of operations and cash flows.
Our pension and health care costs are subject to numerous factors which could cause these costs to change. We have defined benefit pension plans covering substantially all U.S. and Canadian employees. We provide retiree health care benefits to certain of our U.S. salaried and certain hourly employees. Our pension costs are dependent upon numerous factors resulting from actual plan experience and assumptions of future experience. Pension plan assets are primarily made up of equity and fixed income investments. Fluctuations in actual equity market returns; changes in general interest rates and changes in the number of retirees may result in increased pension costs in future periods. Likewise, changes in assumptions regarding current discount rates and expected rates of return on plan assets could also increase pension and health care costs. Although we froze our U.S. defined benefit plan in January 2010 in terms of future service credits, we continue to be subject to market risk on pension plan assets as well as discount rates on long-term obligations. Significant changes in any of these factors could adversely affect our cash flows, financial condition and results of operations.
Our pension plans are currently underfunded, and over time we will be required to make cash payments to the plans, reducing the cash available for our business. We record a liability associated with our pension plans equal to the excess of the benefit obligation over the fair value of plan assets. The benefit liability recorded under the provisions of Accounting Standards Codification (ASC) 715, “Compensation – Retirement Benefits,” at December 31, 2010 was $61 million. Although we expect to have no obligation to fund our plans in 2011, we continually reassess the amount and timing of any discretionary contributions and elected to make such a contribution in in the third quarter of 2011. Over the next several years we will make contributions to the plans that are likely to be material. The amount of such contributions will depend upon a number of factors, principally the actual earnings and changes in values of plan assets, changes in interest rates and the impact of possible funding relief legislation currently under consideration in the U.S. Congress.
A portion of our operations are conducted by joint ventures that we cannot operate solely for our benefit. We conduct a portion of our operations through joint ventures. In joint ventures we share ownership and management of a company with one or more parties who may or may not have the same goals, strategies, priorities or resources as we do. In general, joint ventures are intended to be operated for the benefit of all co-owners, rather than for our exclusive benefit. Operating a business as a joint venture often requires additional organizational formalities as well as time-consuming procedures for sharing information and making decisions. In joint ventures, we are required to pay more attention to our relationship with our co-owners as well as
34

with the joint venture, and if a co-owner changes, our relationship may be adversely affected. In addition, the benefits from a successful joint venture are shared among the co-owners, so that we do not receive all the benefits from our joint ventures.
We depend on third parties for transportation services and increases in costs and the availability of transportation could materially and adversely affect our business and operations. Our business depends on the transportation of a large number of products, both domestically and internationally. We rely primarily on third parties for transportation of the products we manufacture and/or distribute as well as for delivery of our raw materials. In particular, a significant portion of the goods we manufacture and raw materials we use are transported by railroad or trucks, which are highly regulated. If any of our third-party transportation providers were to fail to deliver the goods we manufacture or distribute in a timely manner, we may be unable to sell those products at full value or at all. Similarly, if any of these providers were to fail to deliver raw materials to us in a timely manner, we may be unable to manufacture our products in response to customer demand. In addition, if any of these third parties were to cease operations or cease doing business with us, we may be unable to replace them at reasonable cost. Any failure of a third-party transportation provider to deliver raw materials or finished products in a timely manner could harm our reputation, negatively affect our customer relationships and have a material adverse effect on our financial condition and results of operation. In addition, an increase in transportation rates or fuel surcharges could materially and adversely affect our sales and profitability.
We are subject to significant environmental regulation and environmental compliance expenditures and liabilities. Our businesses are subject to many environmental laws and regulations, particularly with respect to discharges of pollutants and other emissions on or into land, water and air, and the disposal and remediation of hazardous substances or other contaminants and the restoration and reforestation of timberlands. Compliance with these laws and regulations is a significant factor in our business. We have incurred and expect to continue to incur significant expenditures to comply with applicable environmental laws and regulations. Moreover, some or all of the environmental laws and regulations to which we are subject could become more stringent in the future. Our failure to comply with applicable environmental laws and regulations and permit requirements could result in civil or criminal fines or penalties or enforcement actions, including regulatory or judicial orders enjoining or curtailing operations or requiring corrective measures, installation of pollution control equipment or remedial actions.
Some environmental laws and regulations impose liability and responsibility on present and former owners, operators or users of facilities and sites for contamination at such facilities and sites without regard to causation or knowledge of contamination. In addition, we occasionally evaluate various alternatives with respect to our facilities, including possible dispositions or closures. Investigations undertaken in connection with these activities may lead to discoveries of contamination that must be remediated, and closures of facilities may trigger compliance requirements that are not applicable to operating facilities. Consequently, we cannot assure you that existing or future circumstances or developments with respect to contamination will not require significant expenditures by us.
We are involved in various environmental matters, product liability and other legal proceedings. The outcome of these matters and proceedings and the magnitude of related costs and liabilities are subject to uncertainties. The conduct of our business involves the use of hazardous substances and the generation of contaminants and pollutants. In addition, the end-users of many of our products are members of the general public. We currently are and from time to time in the future will be involved in a number of environmental matters and legal proceedings, including legal proceedings involving anti-trust, warranty or non-warranty product liability claims, negligence and other claims, including claims for wrongful death, personal injury and property damage alleged to have arisen out of the use by others of our or our predecessors’ products or the release by us or our predecessors of hazardous substances. Environmental matters and legal matters and proceedings, including class action settlements relating to certain of our products, have in the past caused and in the future may cause us to incur substantial costs. We have established contingency reserves in our consolidated financial statements with respect to the estimated costs of existing environmental matters and legal proceedings to the extent that our management has determined that such costs are both probable and reasonably estimable as to amount. However, such reserves are based upon various estimates and assumptions relating to future events and circumstances, all of which are subject to inherent uncertainties. We regularly monitor our estimated exposure to environmental and litigation loss contingencies and, as additional information becomes known, may change our estimates significantly. However, no estimate of the range of any such change can be made at this time. We may incur costs in respect of existing and future environmental matters and legal proceedings as to which no contingency reserves have been established. We cannot assure you that we will have sufficient resources available to satisfy the related costs and expenses associated with these matters and proceedings.
The valuation of our investment in auction-rate securities (ARS) is subject to uncertainties that are difficult to predict. With the liquidity issues experienced in global credit and capital markets, the ARS held by us have experienced multiple failed auctions as the amount of securities submitted for sale has exceeded the amount of purchase orders. Given the failed auctions, the values of our ARS have been adversely affected. Factors that may further impact the valuation of our ARS 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. If uncertainties in the credit and capital markets continue, these markets deteriorate further or we experience additional ratings
35

downgrades on any investments in our portfolio (including our ARS), we may incur additional impairments to our investment portfolio, which could negatively affect our financial condition, results of operations and cash flows.
Settlements of tax exposures may exceed the amounts we have established for known estimated tax exposures. We maintain reserves for known estimated tax exposures in federal, state and international jurisdictions and uncertain tax positions. Significant income tax exposures may include potential challenges to intercompany pricing, the treatment of financing, acquisition and disposition transactions, the use of hybrid entities and other matters. These exposures are settled primarily through the closure of audits with the taxing jurisdictions and, on occasion, through the judicial process, either of which may produce a result inconsistent with past estimates. We believe that we have established appropriate reserves for estimated exposures; however, if actual results differ materially from our estimates we could experience a material adverse effect on our financial condition, results of operations and cash flows.
Fluctuations in foreign currency exchange rates could result in currency exchange losses. A significant portion of our operations are conducted through foreign subsidiaries. The functional currency for our Canadian subsidiary is the U.S. dollar. The financial statements of this foreign subsidiary are remeasured into U.S. dollars using the historical exchange rate for property, plant and equipment, timber and timberlands, equity and certain other non-monetary assets and liabilities and related depreciation and amortization on these assets and liabilities. These transaction gains or losses are recorded in foreign exchange gains (losses) in the income statement. The functional currency of our Chilean subsidiary is the Chilean peso and the functional currency in our Brazil subsidiary is the Brazilian real. Translation adjustments, which are based upon the exchange rate at the balance sheet date for assets and liabilities and the weighted average rate for the income statement, are recorded in the Accumulated Comprehensive Income (Loss) section of Stockholders’ Equity. Therefore, a movement of the Canadian dollar, the Chilean peso or the Brazilian real relative to the U.S. dollar may have a material adverse effect on our financial condition and results of operations.
Our ability to service our indebtedness, to refinance our indebtedness or to fund our other liquidity needs is subject to various risks. Our ability to make scheduled payments on and to refinance our indebtedness depends on and is subject to our financial and operating performance, which in turn is affected by general and regional economic, financial, competitive, business and other factors, including the availability of financing in the banking and capital markets as well as the other risks described herein. In particular, demand for our products correlates to a significant degree to the level of residential construction activity in North America, which historically has been characterized by significant cyclicality. Over the last several years, housing starts remained below “normal” levels. This reduced level of building was caused, in part, by an increase in the inventory of homes for sale, a more restrictive mortgage market, and slowed economy. There can be no assurance as to when, or if, the housing market will rebound to “normal levels.” We have experienced significant losses from operations and significant net cash used in operating activities in recent periods. Accordingly, we cannot assure you that our business will generate sufficient cash flows from operations or that future borrowings will be available to us in an amount sufficient to enable us to service our debt, to refinance our debt or to fund our other liquidity needs. If we are unable to service our debt obligations or to fund our other liquidity needs, we could be forced to curtail our operations, reorganize our capital structure or liquidate some or all of our assets in a manner that could cause the holders of our securities to experience a partial or total loss of their investment in us.
We have not independently verified the results of third-party research or confirmed assumptions or judgments upon which it may be based, and the forecasted and other forward-looking information contained therein is subject to inherent uncertainties. We refer in this report and other documents that we file with the SEC to historical, forecasted and other forward-looking information published by sources such as FEA, RISI , Random Lengths and the U.S. Census Bureau that we believe to be reliable. However, we have not independently verified this information and, with respect to the forecasted and forward-looking information, have not independently confirmed the assumptions and judgments upon which it is based. Forecasted and other forward looking information is necessarily based on assumptions regarding future occurrences, events, conditions and circumstances and subjective judgments relating to various matters, and is subject to inherent uncertainties. Actual results may differ materially from the results expressed or implied by, or based upon, such forecasted and forward-looking information.
