NOTES TO UNAUDITED 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) 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. 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, 2006.

Adoption of New Accounting Standards

LP adopted Financial Accounting Standards Board (FASB) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement No. 109” (FIN 48) on January 1, 2007. FIN 48 clarifies the accounting and reporting for uncertainties in income tax law. This interpretation prescribes a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns. See Note 6 below for additional information, including the effects of adoption on LP’s Condensed Consolidated Balance Sheets and Consolidated Statement of Stockholders’ Equity.

LP adopted FASB Staff Position AUG AIR-1, “Accounting for Planned Major Maintenance Activities” (FSP AUG AIR-1) on January 1, 2007. FSP AUG AIR-1 prohibits the use of the accrue-in-advance method of accounting for planned major maintenance activities in annual and interim reporting periods. Permitted methods include direct expensing, built-in overhaul and deferral. LP will follow the deferral method in future periods. As a result of this adoption, LP recorded an increase to the beginning balance of retained earnings of $5.2 million or $3.3 million after tax. The impact of the adoption of this standard was immaterial to prior years.

Reclassifications

LP has announced its intent to divest its decking operations. In accordance with Statement of Financial Accounting Standards (SFAS) No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” LP is required to account for the businesses anticipated to be sold within one year as discontinued operations. Accordingly, commencing with the quarter ended June 30, 2007, LP is classifying its decking operations as discontinued operations and has reclassified all periods presented in the same manner.

NOTE 2 – STOCK-BASED COMPENSATION

For the quarters ended June 30, 2007 and 2006, the total compensation expense related to LP’s stock-based compensation plans was $1.8 million. For the six month periods ended June 30, 2007 and 2006, the total compensation expense related to all of LP’s stock-based compensation plans was $3.3 million and $3.3 million. At June 30, 2007, 5,334,163 shares were available under the current stock award plans for stock-based awards. For the six month period ended June 30, 2007, the fair value of the options granted was estimated using the Black-Scholes option-pricing model with the following weighted-average assumptions: a risk free interest rate of 4.82%; an expected volatility factor for the market price of the Company’s common stock of 29.7% (based upon historical volatility over the expected life); a dividend yield of 2.6%; and an expected life of 4 years (based upon historical experience). For the six month period ended June 30, 2006, the fair value of the options granted was estimated using the Black-Scholes option-pricing model with the following weighted average assumptions: a risk free interest rate of 4.5%; an expected volatility factor for the market price of the Company’s common stock of 45.2% (based upon historical volatility over the expected life); a dividend yield of 1.9%; and an expected life of 4 years (based upon historical experience). The weighted-average fair value of each option or stock settled stock appreciation right (SSARs) granted during the six month period ended June 30, 2007 and June 30, 2006 was $5.54 and $10.26.

NOTE 3 – EARNINGS PER SHARE

Basic net income per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted-average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares primarily consist of employee stock options, SSARs, restricted stock units and restricted common stock.

Statement of Financial Accounting Standards (SFAS) No. 128, “Earnings per Share,” requires that employee equity share options, non-vested shares and similar equity instruments granted by the Company be treated as potential common shares outstanding in computing diluted earnings per share. Diluted shares outstanding include the dilutive effect of in-the-money options, which is calculated based on the average share price for each fiscal period using the treasury stock method. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of tax benefits that would be recorded in additional paid-in capital when the award becomes deductible are assumed to be used to repurchase shares.

Net income (loss) per share	$	(0.22	)	$	0.52		$	(0.58	)	$	1.31

Stock options and SSARs to purchase approximately 3.2 million shares for the quarter ended June 30, 2007 and the six month period ended June 30, 2007 were not included in the computation of diluted earnings (loss) per share due to LP’s net loss position in continuing operations. Stock options and SSARS to purchase approximately 0.9 million shares at June 30, 2006 were considered anti-dilutive for purposes of LP’s earnings per share calculation due to the exercise price being greater than the average fair market price.

NOTE 4 – INVENTORIES

Inventories are valued at the lower of cost or market. Inventory cost includes materials, labor and operating overhead. The LIFO (last-in, first-out) method is used for certain log inventories with remaining inventories valued at FIFO (first-in, first-out) or average cost. The major types of inventories are as follows (work in process is not material):

NOTE 5 – BUSINESSES HELD FOR SALE AND DIVESTITURES

At June 30, 2007 and 2006 and for the first six months of 2007 and 2006, LP’s discontinued operations included its decking operations and residual charges from previously discontinued operations.

Sales and losses for these businesses are as follows:

	Quarter Ended June 30,						Six Months Ended June 30,
Dollar amounts in millions	2007			2006			2007			2006

Sales	$	11.7		$	16.5		$	23.2		$	38.5

Loss from discontinued operations, net of tax	$	(7.7	)	$	(1.0	)	$	(9.0	)	$	(2.3	)

In the second quarter of 2007, LP recorded a loss of $9.5 million associated with impairment charges on assets held for sale to reduce the carrying value of these assets to their estimated sales price, which approximates the estimated fair market value of such assets, net of related selling expenses.

The assets of the discontinued operations included in the accompanying condensed consolidated balance sheets as of June 30, 2007 and December 31, 2006 are as follows:

Dollar amounts in millions	June 30, 2007			December 31, 2006

Inventories	$	18.5		$	24.5

Total long-term assets of discontinued operations	33.9			44.6

Total assets of discontinued operations	$	52.4		$	69.1

NOTE 6 – INCOME TAXES

Accounting standards require that income tax expense be determined by applying the estimated annual effective tax rate (based upon estimated annual amounts of taxable income and expense) by income component for the year to year-to-date income or loss at the end of each quarter, further adjusted by any changes in reserve requirements or the impact of statutory tax rate changes, if any. 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.

Discontinued operations	(12.6		)	(1.7		)	(14.8		)	(3.8		)
	(39.1		)	73.4			(108.6		)	200.6
Total tax provision (benefit)	(15.8		)	18.3			(48.0		)	61.8
Net income (loss)	$	(23.3	)	$	55.1		$	(60.6	)	$	138.8

For the six months ended June 30, 2007, the primary differences between the U.S. statutory rate of 35% and the effective rate on continuing operations relates to the Company’s foreign debt structure, state income taxes and the favorable resolution of an outstanding state tax contingency. For the six months ended June 30, 2006, the primary differences between the U.S. statutory rate of 35% and the effective rate on continuing operations relates to the Company’s foreign debt structure, state income taxes, and a second quarter reduction in LP’s Canadian deferred tax liabilities due to an enacted decrease in the statutory income tax rate.

The components and associated estimated effective income tax rates applied to the six month periods ended June 30, 2007 and 2006 are as follows:

	Six Months Ended June 30,
	2007					2006
	Tax Benefit			Tax Rate		Tax Provision (Benefit)			Tax Rate
Continuing operations	$	(42.2	)	45	%	$	63.3		31	%
Discontinued operations	(5.8		)	39	%	(1.5		)	39	%
	$	(48.0	)	44	%	$	61.8		31	%

LP adopted FIN 48 on January 1, 2007. As a result of the implementation, LP recorded $12.9 million as a FIN 48 liability for unrecognized tax positions of which $0.3 million (net of federal benefit on state issues) would impact

LP’s effective tax rate if recognized. This FIN 48 liability is recorded in “Other long-term liabilities” in the Condensed Consolidated Balance Sheets as of June 30, 2007. The implementation also resulted in a $1.2 million decrease to LP’s January 1, 2007 balance of retained earnings. LP does not expect to recognize any decrease in unrecognized tax benefits in the ensuing twelve months.

LP and its domestic subsidiaries are subject to U.S. federal income tax as well as income taxes of multiple state jurisdictions. Its foreign subsidiaries are subject to income tax in Canada and Chile. U.S. federal income tax examinations for the years through 2004 have been effectively settled. LP has been advised that a U.S. federal audit for 2005 and 2006 will begin in the fourth quarter of 2007. LP is subject to state and local income tax examinations for the tax years 2000 through 2006. Canadian returns have been audited through 1999 and Revenue Canada began an examination of the years 2002 through 2004 during the second quarter of 2007.

LP’s policy is to record interest paid or received with respect to income taxes as interest expense or interest income, respectively, in the Consolidated Statements of Income. Penalties related to unrecognized tax benefits or assessments are charged to income tax expense. Upon the adoption of FIN 48, LP recorded $0.9 million of interest expense (net of tax benefit) as a reduction to retained earnings and no penalties. During the first six months of 2007, an additional $0.6 million was accrued as interest expense.

NOTE 7 – OTHER OPERATING CREDITS AND CHARGES, NET

The major components of “Other operating credits and charges, net” in the Consolidated Statements of Income for the quarter and six months periods ended June 30, 2007 and 2006 are reflected in the table below and are described in the paragraphs following the table:

	Quarter Ended June 30,				Six Months Ended June 30,
Dollar amounts in millions	2007		2006		2007		2006

Timber recovery	$	1.5	$	—	$	1.5	$	—
Insurance settlement	17.7		—		17.7		—
Other	—		—		—		(0.1		)
	$	19.2	$	—	$	19.2	$	(0.1	)

In the second quarter of 2007, LP recorded a gain of $17.7 million associated with a gain from a favorable verdict on a legal suit associated with our insurance on hardboard siding and a gain of $1.5 million associated with a settlement with the Canadian government on the reduction of certain of LP’s timber licenses in British Columbia.

NOTE 8 – GAIN (LOSS) ON SALE OR IMPAIRMENT OF LONG-LIVED ASSETS

The major components on “Gain (loss) on sale or impairment of long-lived assets” in the Consolidated Statements of Income for the quarter and six months period ended June 30, 2007 and 2006 are reflected in the following table:

	Quarter Ended June 30,					Six Months Ended June 30,
Dollar amounts in millions	2007		2006			2007			2006

Gain (loss) on sale of long-lived assets	$	0.3	$	(0.1	)	$	(0.2	)	$	—
Impairment charges on long-term assets	—		—			(5.0		)	—
	$	0.3	$	(0.1	)	$	(5.2	)	$	—

In the first quarter of 2007, LP recorded an impairment charge of $5.0 million on a sawmill located in Quebec that is held for sale to reduce the carrying value of this equipment to its estimated sales price, which approximates the estimated fair market value, net of related selling expenses.

NOTE 9 – INVESTMENTS IN AND ADVANCES TO AFFILIATES

LP has investments in affiliates that are either accounted for under the equity method or the cost method based upon the specific terms of the agreement as well as advances to affiliates. The significant components of these investments and advances are as follows:

Dollar amounts in millions	June 30, 2007		December 31, 2006

Investments accounted for under the equity method	$	165.3	$	168.4
Investments accounted for under the cost method	44.5		44.5
Total	$	209.8	$	212.9

At June 30, 2007, LP’s significant equity method investees and its ownership interest and principal business activity in each investee, were as follows:

	Ownership %
U.S. GreenFiber	50%	Established to manufacture and sell cellulose insulation products
Abitibi – LP	50%	Established to construct and operate I-Joist facilities in Quebec, Canada
Canfor – LP	50%	Established to construct and operate an OSB facility in British Columbia, Canada

These investments do not meet the Regulation S-X significance test requiring the inclusion of the separate investee financial statements or summarized financial information.

LP sells products and raw materials to the Abitibi-LP entity and purchases products for resale from the Abitibi-LP and Canfor-LP entities. 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 June 30, 2007 and 2006, LP sold $4.1 million and $8.7 million of products to Abitibi-LP and purchased $22.0 million and $30.1 million of I-joist from Abitibi-LP. LP also purchased $19.0 million and $28.1 million of OSB from Canfor-LP during the quarters ended June 30, 2007 and 2006. For the six months ended June 30, 2007 and 2006, LP sold $7.3 million and $17.6 million of products to Abitibi-LP and purchased $36.9 million and $53.7 million of I-joist from Abitibi-LP. LP also purchased $36.8 million and $44.8 million of OSB from Canfor-LP during the six months ended June 30, 2007 and 2006.

NOTE 10 – 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, 2006.

NOTE 11 – 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 assets based upon the anticipated cash flows that result from estimates of future demand, pricing and production costs assuming certain levels of planned capital expenditures. However, should the markets for the relevant products continue to remain at levels significantly below cycle average pricing or should LP decide to invest capital in alternative projects, it is possible that impairment charges will be required.

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 12 – CONTINGENCY RESERVES

LP is involved in various legal proceedings incidental to LP’s business and is subject to a variety of environmental and pollution control laws and regulations in all jurisdictions in which it operates. LP maintains reserves for these various contingencies as follows:

Dollar amounts in millions	June 30, 2007			December 31, 2006

Environmental reserves	$	8.8		$	7.7
Hardboard siding reserves	18.9			25.3
Other reserves	1.4			1.6
Total contingency reserves	29.1			34.6
Current portion of contingency reserves	(9.0		)	(9.0		)
Long-term portion of contingency reserves	$	20.1		$	25.6

Hardboard Siding Reserves

LP has established reserves relating to certain liabilities associated with products manufactured that were the subject of a nationwide class action lawsuit. This settlement agreement relates to a nationwide class action suit involving hardboard siding manufactured or sold by corporations acquired by LP in 1999 and installed prior to May 15, 2000 and 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, 2006.

Additional Siding Matters

On October 15, 2002, a jury returned a verdict of $29.6 million against LP in a Minnesota State Court action entitled Lester Building Systems, a division of Butler Manufacturing Company, and Lester’s of Minnesota, Inc., v. Louisiana-Pacific Corporation and Canton Lumber Company. On December 13, 2002, the District of Oregon, which maintains jurisdiction over a previously settled nationwide class action suit involving OSB siding manufactured by us and installed prior to January 1, 1996, permanently enjoined the Minnesota state trial court from entering judgment against us with respect to $11.2 million of the verdict that related to siding that was subject to the nationwide OSB siding settlement. LP satisfied this verdict, less the enjoined amount, during the second quarter of 2004. Lester’s appealed the District Court’s injunction to the Ninth Circuit Court of Appeals and, on October 24, 2005, the Court of Appeals decided in a 2 to 1 decision to vacate the District Court’s injunction. As a result of this decision, the injunction was lifted and the state court judgment of $11.2 million was entered on December 22, 2006. On January 19, 2007, LP filed its notice of appeal to the Minnesota State Court of Appeals. Based upon the information currently available, LP believes that any further liability related to this case is remote and, accordingly, have not recorded any accrual with respect to our potential exposure.

Lockhart Wood Treatment Facility

During the third quarter of 2004, LP received a pre-litigation settlement demand letter from a law firm purporting to represent more than 1,400 potential plaintiffs who allegedly experienced various personal injuries and property damages as a result of the alleged release of chemical substances from LP’s wood treatment facility in Lockhart, Alabama during the period from 1953 to 1998. The letter was also addressed to Pactiv Corporation (“Pactiv”), from whom LP acquired the facility in 1983. LP, Pactiv, and the potential plaintiffs agreed to exchange information and enter into non-binding mediation, which failed in December 2005. In the months following the failed mediation, plaintiffs’ attorneys filed 19 separate lawsuits purporting to represent a total of 1,429 plaintiffs. Each of these cases was filed in, or removed to, the Federal District Court of Alabama which court has designated a lead case under the caption Melanie Chambers v. Pactiv Corp et al, CV 2:06-CV-00083-LES-CSC. Due to the numerous uncertainties associated with the matters alleged in the letter and subsequent lawsuits, including uncertainties regarding the existence, nature, magnitude and causation of the alleged wrongful death, injuries and property damage, responsibility therefore and defenses thereto, LP is not presently able to quantify LP’s financial exposure, if any, relating to such matters. LP intends to defend these suits vigorously.

Antitrust Litigation

LP has been named as one of a number of defendants in multiple class action complaints filed on or after February 26, 2006 in the United States District Court for the Eastern District of Pennsylvania. These complaints have been dismissed or consolidated into two complaints under one caption: In Re OSB Anti-Trust Litigation, Master File No. 06-CV-00826 (PD). The first complaint is a consolidated amended class action complaint filed on March 31, 2006 in which plaintiffs seek to certify a class consisting of persons and entities who directly purchased OSB from the defendants from May 1, 2002 through the date the complaint was filed (the direct purchaser complaint). The second complaint is a consolidated amended class action complaint, filed on June 15, 2006, in which the plaintiffs seek to certify a class consisting of persons and entities who indirectly purchased OSB from the defendants from May 1, 2002 through the date the complaint was filed (the indirect purchaser complaint).

The plaintiffs, in both amended and consolidated complaints described above, seek treble damages in unspecified amounts alleged to have resulted from a conspiracy among the defendants to fix, raise, maintain and stabilize the prices at which OSB is sold in the United States, in violation of Section 1 of the Sherman Act, 15 U.S.C. §1. The plaintiffs in the indirect purchaser complaint also seek similar remedies under individual state anti-trust and competition laws as well as consumer protection laws. LP believes that the claims asserted are without merit, and

intends to defend this matter vigorously. LP is unable to predict whether the court will declare these actions to be class actions, and likewise is unable to predict the potential financial impact of these actions.

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 – DEFINED BENEFIT PENSION PLANS

The following table sets forth the net periodic pension cost for LP’s defined benefit pension plans during the quarters and six months periods ended June 30, 2007 and 2006. The net periodic pension cost included the following components:

	Quarter Ended June 30,						Six Months Ended June 30,
Dollar amounts in millions	2007			2006			2007			2006

Service cost	$	2.4		$	2.5		$	4.9		$	5.0
Interest cost	3.9			3.9			7.9			7.8
Expected return on plan assets	(4.8		)	(4.6		)	(9.5		)	(9.2		)
Amortization of prior service cost	0.3			0.3			0.6			0.6
Amortization of net loss	1.5			1.9			3.0			3.8
Net periodic pension cost	$	3.3		$	4.0		$	6.9		$	8.0

Through June 30, 2007, LP recognized $6.9 million of pension expense for all of LP’s defined benefit plans. LP presently anticipates recognizing, assuming no curtailment or settlement expenses are required, an additional $6.9 million of pension expense in the remainder of 2007 for a total of $13.8 million.

Through June 30, 2007, LP made $9 million of pension contributions for all of LP’s defined benefit plans. LP presently anticipates making up to $1 million of additional pension contributions for the plans during the remainder of 2007.

NOTE 14 – 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 20 of the Notes to the financial statements included in LP’s Annual Report on Form 10-K for the year ended December 31, 2006 for further discussion of LP’s guarantees and indemnifications.

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 first six months of 2007 and 2006 are summarized in the following table:

Dollar amounts in millions	June 30, 2007			June 30, 2006

Beginning balance, December 31,	$	28.8		$	32.3
Accrued to expense	1.8			2.8
Payments made	(1.8		)	(3.6		)
Total warranty reserves	28.8			31.5
Current portion of warranty reserves	(7.0		)	(7.0		)
Long-term portion of warranty reserves	$	21.8		$	24.5

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 15 – RECENT AND PROSPECTIVE ACCOUNTING PRONOUNCEMENTS

In September 2006, the FASB finalized SFAS 157, “Fair Value Measurements” (SFAS 157) which will become effective in 2008. This Statement defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements; however, it does not require any new fair value measurements. The provisions of SFAS 157 will be applied prospectively to fair value measurements and disclosures beginning in the first quarter of 2008 and is not expected to have a material effect on LP’s Consolidated Financial Statements.

In February 2007, the FASB issued SFAS 159, “The Fair Value Option for Financial Assets and Financial Liabilities, Including an Amendment of FASB Statement No. 115,” (SFAS 159) which will become effective in 2008. SFAS 159 permits entities to measure eligible financial assets, financial liabilities and firm commitments at fair value, on an instrument-by-instrument basis, that are otherwise not permitted to be accounted for at fair value under other generally accepted accounting principles. The fair value measurement election is irrevocable and subsequent changes in fair value must be recorded in earnings. LP will adopt this Statement in fiscal year 2008 and is currently evaluating if it will elect the fair value option for any of its eligible financial instruments and other items.

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans — an amendment of FASB Statements No. 87, 88, 106 and 132(R)” (SFAS 158). This statement requires balance sheet recognition of the overfunded or underfunded status of pension and postretirement benefit plans. Under SFAS 158, actuarial gains and losses, prior service costs or credits, and any remaining transition assets or obligations that have not been recognized under previous accounting standards must be recognized in Accumulated Comprehensive Loss, net of tax effects, until they are amortized as a component of net periodic benefit cost. In addition, the measurement date (the date at which plan assets and the benefit obligation are measured) is required to be the Company’s fiscal year end. Presently, LP uses an October 31 measurement date for a majority of its pension and postretirement benefit plans. LP adopted the recognition and disclosure provisions of SFAS 158 effective December 31, 2006, except for the measurement date provisions, which are not required until fiscal years ending after December 15, 2008.

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 for some of our building products. Our manufacturing facilities are primarily located in the U.S. and Canada, but we also operate a facility in Chile and are in the process of completing construction of a second facility in Chile.

To serve these markets, we operate in three segments: Oriented Strand Board (OSB), Siding, and Engineered Wood Products (EWP). OSB is the most significant segment, accounting for more than 45% of sales during the six month period ended June 30, 2007 and more than 55% of sales in the six month period ended June 30, 2006.

Our most significant product, 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. However, industry analysts have predicted that the expectation of new capacity coupled with lower new housing activity will likely lead to continued low pricing for at least the next twelve months. During the first six months of 2007, commodity OSB prices were significantly lower as compared to the same period in the prior year.

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, 2006.

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, 2006 is a discussion of our significant accounting policies and significant accounting estimates and judgments. The discussion of each of the policies and estimates outlines the specific accounting treatment related to each of these accounting areas.

Accounting Policies

There are several policies that we have adopted and implemented from among acceptable alternatives that could lead to different financial results had another policy been chosen:

Inventory valuation. We use the LIFO (last-in, first-out) method for some of our log inventories with the remaining inventories valued at FIFO (first-in, first-out) or average cost. Our inventories would have been approximately $2.8 million higher if the LIFO inventories were valued at average cost as of June 30, 2007.

Property, plant and equipment. We principally use the units of production method of depreciation for machinery and equipment. This method amortizes the cost of machinery and equipment over the estimated units that will be produced during its estimated useful life.

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 2007, 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 analyses 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 June 30, 2007, we excluded from our estimates approximately $0.6 million of potential environmental liabilities that we estimate will be allocated to third parties pursuant to existing and anticipated future cost sharing arrangements.

Impairment of Long-Lived Assets. We review the long-lived assets held and used by us (primarily property, plant and equipment and timber and timberlands) for impairment when events or changes in circumstances indicate that the carrying amount of assets may not be recoverable. 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, on assets held and used, impairments are recognized when the book values exceed our estimate of the undiscounted future net cash flows associated with the affected assets. The key assumptions in estimating these cash flows include future production volumes and pricing of commodity or specialty products and future estimates of expenses to be incurred. 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. These prices are estimated from information gathered from industry research firms, research reports published by investment analysts and other published forecasts. Our estimates of expenses are based upon our long-range internal planning models and our expectation that we will continue to reduce product costs that will partially offset inflationary impacts.

When impairment is indicated, the book values of the assets to be held and used are written down to their estimated fair value, which is generally based upon discounted future cash flows. Assets to be disposed of 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 June 30, 2007, we had established valuation allowances against certain deferred tax assets, primarily related to foreign tax credit carryovers and credit carryovers and foreign capital loss carryovers. We have not established valuation allowances against other deferred tax assets based upon expected future taxable income and/or tax strategies planned to mitigate the risk of impairment of these assets. 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.

Goodwill. Goodwill and other intangible assets that are deemed to have an indefinite life are no longer amortized. However, these indefinite life assets are tested for impairment on an annual basis, and otherwise when indicators of impairment are determined to exist, by applying a fair value based test. The process of evaluating the potential impairment of goodwill is highly subjective and requires significant judgments at many points during the analysis. In testing for potential impairment, the estimated fair value of the reporting unit, as determined based upon cash flow forecasts, is compared to the book value of the reporting unit. The key assumptions in estimating these cash flows include future production volumes and pricing of commodity products and future estimates of expenses to be incurred. 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. These prices are estimated from information gathered from industry research firms, research reports published by investment analysts and other published forecasts. Our estimates of expenses are based upon our long-range internal planning models and our expectation that we will reduce product costs that will offset inflationary impacts. 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, if any, are subject to substantial uncertainties. Consequently, as additional information becomes known, we may change our estimates significantly.

Pension Plans. Most of our U.S. employees and some of our Canadian employees participate in defined benefit pension plans sponsored by LP. We account for the consequences of our sponsorship of these plans in accordance with accounting principles generally accepted in the U.S., which require us to make actuarial assumptions that are used to calculate the related assets, liabilities and expenses recorded in our financial statements. While we believe we have a reasonable basis for these assumptions, which include assumptions regarding long-term rates of return on plan assets, life expectancies, rates of increase in salary levels, rates at which future values should be discounted to determine present values and other matters, the amounts of our pension related assets, liabilities and expenses recorded in our financial statements would differ if we used other assumptions. See further discussion related to pension plans below under the heading “Defined Benefit Pension Plans” and in Note 13 of the Notes to the financial statements included in item 8 of our Annual Report on Form 10-K for the year ended December 31, 2006.

Workers’ Compensation. We are self-insured for workers’ compensation in most U.S. states. 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.

RESULTS OF OPERATIONS

Our net loss for the second quarter of 2007 was $23 million, or $0.22 per diluted share, on sales of $461 million, compared to net income for the second quarter of 2006 of $55 million, or $0.52 per diluted share, on sales of $637 million. For the second quarter of 2007, loss from continuing operations was $16 million, or $0.15 per diluted share, compared to income from continuing operations of $56 million, or $0.53 per diluted share, for the second quarter of 2006.

Our net loss for the six months ended June 30, 2007 was $61 million, or $0.58 per diluted share, on sales of $856 million, compared to net income for the six months ended June 30, 2006 of $139 million, or $1.31 per diluted share, on sales of $1.3 billion. For the six months ended June 30, 2007, loss from continuing operations was $52 million,

or $0.50 per diluted share, compared to income from continuing operations of $141 million, or $1.33 per diluted share, for the six months ended June 30, 2006.

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, profits and depreciation, amortization and cost of timber harvested for this segment are as follows:

	Quarter Ended June 30,							Six Months Ended June 30,
	2007			2006		Change		2007			2006		Change
Net sales	$	223		$	355	-37	%	$	412		$	752	-45	%
Operating profits (losses)	$	(45	)	$	62	-172	%	$	(109	)	$	173	-163	%
Depreciation, amortization and cost of timber harvested	$	17		$	21			$	33		$	43

Percent changes in average sales prices and unit shipments for the quarter and six months ended June 30, 2007 compared to the quarter and six months ended June 30, 2006 are as follows:

	Quarter Ended June 30, 2007 versus 2006				Six Months Ended June 30, 2007 versus 2006
	Average Net Selling Price		Unit Shipments		Average Net Selling Price		Unit Shipments

Commodity OSB	(38	)%	(2	)%	(42	)%	(8	)%

OSB prices declined for the second quarter and first six months of 2007 as compared to the corresponding periods of 2006 due to weakening of housing demand coupled with increased industry capacity. The impact of the reduction in selling price accounted for a decrease in net sales and operating profits of approximately $123 million for the quarter and $274 million for the six month period. For the quarter and six month periods ended June 30, 2007 as compared to the corresponding periods of 2006, the decline in sales volume is due to three factors: our St. Michel, Quebec OSB mill was curtailed throughout the first six months of 2007 (and likely will not run in 2007), production outages caused by wood shortages and maintenance aberrations, and the effect of the CN Railroad strike (primarily in the first quarter). These declines were partially offset by higher production from our Peace Valley joint venture mill.

SIDING

Our siding segment produces and markets wood-based siding and related accessories and interior hardboard products, together with commodity OSB products from one mill which can produce both OSB and OSB-based exterior products.

Segment sales, profits and depreciation, amortization and cost of timber harvested for this segment are as follows:

	Quarter Ended June 30,						Six Months Ended June 30,
	2007		2006		Change		2007		2006		Change
Net sales	$	131	$	149	-12	%	$	235	$	269	-13	%
Operating profits	$	17	$	23	-25	%	$	27	$	42	-36	%
Depreciation, amortization and cost of timber harvested	$	5	$	5			$	10	$	10

Sales in this segment by product line are as follows:

	Quarter Ended June 30,						Six Months Ended June 30,
	2007		2006		Change		2007		2006		Change
OSB-based exterior products	$	76	$	91	(16	)%	$	136	$	154	(12	)%
Commodity OSB	9		14		(36	)%	14		31		(55	)%
Hardboard siding	46		44		5	%	85		84		1	%
Total	$	131	$	149	(12	)%	$	235	$	269	(13	)%

Percent changes in average sales prices and unit shipments for the quarter and six month period ended June 30, 2007 compared to the quarter and six month period ended June 30, 2006 are as follows:

	Quarter Ended June 30, 2007 versus 2006				Six Months Ended June 30, 2007 versus 2006
	Average Net Selling Price		Unit Shipments		Average Net Selling Price		Unit Shipments

OSB-based exterior products	5	%	(20	)%	3	%	(15	)%
Commodity OSB	(36	)%	5	%	(43	)%	(17	)%
Hardboard siding	1	%	2	%	4	%	(5	)%

For the second quarter and first six months of 2007 compared to the corresponding periods in the prior year, sales volume decreased in our OSB-based exterior products as well as for commodity OSB produced at one of our siding mills. These declines were a result of reduced demand due to significantly lower housing starts. Sales prices in our OSB-based siding product line increased slightly as compared to the corresponding periods in the prior year due to changes in product mix, as well as a price increase implemented in August of 2006. In our hardboard product line, sales volume declined and sales prices increased due to a change in product mix that included more siding and less industrial board.

Overall, declines in operating results for our siding segment for the second quarter and the first six months of 2007 compared to the same periods of 2006 were primarily due to lower sales volumes and prices in the OSB commodity products sold from this segment.

ENGINEERED WOOD PRODUCTS

Our engineered wood products (EWP) segment manufactures and distributes laminated veneer lumber (LVL), I-Joists and other related products.

Segment sales, profits and depreciation, amortization and cost of timber harvested for this segment are as follows:

	Quarter Ended June 30,						Six Months Ended June 30,
	2007		2006		Change		2007		2006		Change
Net sales	$	86	$	110	(22	)%	$	166	$	222	(25	)%
Operating profits	$	4	$	9	(57	)%	$	10	$	20	(49	)%
Depreciation, amortization and cost of timber harvested	$	3	$	3			$	7	$	7

Sales in this segment by product line are as follows:

	Quarter Ended June 30,						Six Months Ended June 30,
	2007		2006		Change		2007		2006		Change
LVL	$	37	$	48	(23	)%	$	72	$	99	(27	)%
I-Joist	38		55		(31	)%	70		103		(32	)%
Related products	11		7		57	%	24		20		20	%
Total	$	86	$	110	(22	)%	$	166	$	222	(25	)%

Percent changes in average sales prices and unit shipments for the quarter and six months ended June 30, 2007 compared to the quarter and six months ended June 30, 2006 are as follows:

	Quarter Ended June 30, 2007 versus 2006				Six Months Ended June 30, 2007 versus 2006
	Average Net Selling Price		Unit Shipments		Average Net Selling Price		Unit Shipments
LVL	(13	)%	(17	)%	(11	)%	(21	)%
I-Joist	(10	)%	(17	)%	(12	)%	(21	)%

During the second quarter and the first six months of 2007 as compared to the corresponding periods of 2006, we saw reductions in sales volumes in both LVL and I-Joist. These declines are attributed to the continuing slowdown in the housing market. For the quarter and six months ended June 30, 2007, net average selling prices declined as we continued to see price pressure caused by lower demand.

For the second quarter and first six months of 2007 compared to the corresponding periods in the prior year, the results of operations for EWP were lower primarily due to lower volume and reductions in sales prices, which were partially offset by lower raw material costs (primarily OSB and lumber).

OTHER PRODUCTS

Our other products category includes our moulding business, Chilean operations and our joint venture that produces and sells cellulose insulation. Additionally, this category includes our remaining timber and timberlands and other minor products, services and operations closed prior to January 1, 2002.

Segment sales, profits and depreciation, amortization and cost of timber harvested for this category are as follows:

	Quarter Ended June 30,							Six Months Ended June 30,
	2007			2006		Change		2007			2006		Change
Net sales	$	24		$	23	2	%	$	48		$	48	1	%
Operating profits	$	(3	)	$	5	(160	)%	$	(1	)	$	10	(106	)%
Depreciation, amortization and cost of timber harvested	$	1		$	1			$	2		$	2

Sales in this segment by product line are as follows:

	Quarter Ended June 30,						Six Months Ended June 30,
	2007		2006		Change		2007		2006		Change
Moulding	$	10	$	10	0	%	$	21	$	22	-5	%
Chile	10		10		0	%	18		19		-5	%
Other	4		3		33	%	9		7		29	%
Total	$	24	$	23	5	%	$	48	$	48	0	%

For the second quarter and first six months of 2007 compared to the corresponding periods of 2006, we saw a decline in sales volumes for our moulding business due to the prior loss of a home center customer. In our Chilean operations, sales pricing as well as volumes remained relatively flat.

Overall, the operating profits of this category were lower compared to the second quarter and first six months of 2006, primarily due to the low sales volumes in our moulding operations and increased residual costs associated with several non operating facilities.

GENERAL CORPORATE AND OTHER EXPENSE, NET

For the second quarter and first six months of 2007 compared to the same periods in 2006, general corporate expenses declined. 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 decline in the second quarter and first six months of 2007 as compared to the same periods in 2006 resulted from reduced legal expenses associated with a resolved lawsuit as well as lower accruals for management incentives based on continued weak market conditions.

INTEREST EXPENSE AND INVESTMENT INCOME

Interest expense in the second quarter and first six months of 2007 was lower compared to the corresponding periods of 2006 due to higher capitalized interest associated with on-going capital projects. For the second quarter of 2007, we capitalized $4.1 million in interest expense as compared to $0.8 million in the second quarter 2006. For the first six months of 2007 we capitalized $7.0 million of interest expense as compared to $1.4 million in the same period in 2006. Additionally, during the second quarter of 2006, we repaid $110 million Canadian on our term loan and therefore generated less expense in the second quarter and first six months of 2007 on this loan.

DISCONTINUED OPERATIONS

Included in discontinued operations for the second quarter and first six months of 2007 and 2006 are the results of the operations of mills that have been or are to be divested. At June 30, 2007, LP classified its composite decking operations as discontinued.

For the second quarter and first six months of 2007 compared to the corresponding periods of 2006, we saw a decline in sales volumes for our decking business. Lower sales volumes in our decking operations are related to slower shipments to our distributors due to lower end user demand as well as our decision not to enter into any special selling programs in the winter months as we have in past years.

Included in the operating losses of discontinued operations for the second quarter of 2007 is a $9.5 million impairment charge on assets held for sale to reduce the carrying value to the estimated sales price less selling costs.

INCOME TAXES

Income (loss) before taxes and tax provision (benefit) for the quarter and six month periods ended June 30, 2007 and 2006 were as follows:

	Quarter Ended June 30,						Six Months Ended June 30,
	2007			2006			2007			2006
Continuing operations	$	(26.5	)	$	75.1		$	(93.8	)	$	204.4
Discontinued operations	(12.6		)	(1.7		)	(14.8		)	(3.8		)
	(39.1		)	73.4			(108.6		)	200.6
Total tax provision (benefit)	(15.8		)	18.3			(48.0		)	61.8
Net income (loss)	$	(23.3	)	$	55.1		$	(60.6	)	$	138.8

Accounting standards require that income tax expense be determined using the estimated annual effective tax rate (based upon estimated annual amounts of taxable income and expense) by income component for the year applied to year-to-date income or loss at the end of each quarter, further adjusted by any changes in reserve requirements or the impact of statutory tax rate changes, if any. 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.

The components and associated estimated effective income tax rates applied to the six month periods ended June 30, 2007 and 2006 are as follows:

	Six Months Ended June 30,
	2007					2006
	Tax Benefit			Tax Rate		Tax Provision (Benefit)			Tax Rate
Continuing operations	$	(42.2	)	45	%	$	63.3		31	%
Discontinued operations	(5.8		)	39	%	(1.5		)	39	%
	$	(48.0	)	44	%	$	61.8		31	%

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. We account for all of these plans and provide aggregated disclosures about these plans in the Notes to our financial statements as required by SFAS No. 158 “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans – an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (SFAS 158), the recognition and disclosure requirements of which were adopted as of December 31, 2006. See Note 13 of the Notes to financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2006. We estimate that our net periodic pension cost for 2007 will be approximately $13.8 million. This estimate assumes that we will have no curtailment or settlement expenses in 2007. If a curtailment or settlement does occur in 2007, this estimate may change significantly. We estimate that we will contribute approximately $10 million to these plans in 2007. As of June 30, 2007, we had contributed approximately $9 million to these plans. At December 31, 2006, we had $76.7 million of net actuarial loss and $6.2 million of prior service cost included in accumulated other comprehensive loss. Of these amounts, we expect to recognize a net actuarial loss of $6.0 million and prior service cost of $1.2 million as components of net periodic pension cost in 2007, which will account for approximately 52% of our estimated 2007 net periodic pension cost.

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, 2006, Note 18 to the Notes to the financial statements contained therein and Item 1, Legal Proceedings, in Part II of this report.

HARDBOARD SIDING LITIGATION UPDATE

The following discussion updates 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, 2006.

Cumulative statistics under hardboard settlements are as follows:

	June 30, 2007	March 31, 2007	December 31, 2006
Requests for claims	59,800	57,300	55,300
Completed claims received	45,300	43,000	40,700
Completed claims pending	1,200	1,600	2,100
Claims dismissed	9,900	9,800	9,600
Claims settled	34,200	31,600	29,000

The average payment amount for settled claims as of June 30, 2007, March 31, 2007 and December 31, 2006 was $1,100. 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.

ENVIRONMENTAL COMPLIANCE

The U.S. government has recently modified its position with respect to the enacted regulations related to Maximum Achievable Control Technology (MACT). MACT regulations govern the manner in which we measure and control the emissions from our manufacturing facilities into the air. Based upon the current interpretation of these regulations, we anticipate, based upon our current facilities; that we could be required to spend between $7 million and $10 million by October 2008 to comply with these regulations.

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 or debt 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, making capital expenditures and paying dividends to our stockholders. 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 six months of 2007, we used $10 million of cash from operations compared to net cash provided by operating activities of $156 million in the first six months of 2006. The decrease in cash provided by operations in the first six months of 2007 was primarily a result of lower operating profits from our OSB business compared to the same period of 2006.

INVESTING ACTIVITIES

During the first six months of 2007, we used approximately $15 million in investing activities of cash. Capital expenditures for the first six months of 2007 were $132 million and related primarily to the costs associated with our OSB mill in Alabama and OSL (oriented strand lumber) facility in Houlton, Maine that are under construction. Additionally, we contributed $5 million to our joint ventures with Canfor Corporation and Abitibi Consolidated for working capital requirements. We also used approximately $1.5 billion to purchase investments with maturities in excess of 90 days and received $1.7 billion on the sale of these types of investments.

During the first six months of 2006, we used approximately $148 million of cash in investing activities. Capital expenditures in the first six months of 2006 were $65 million and related primarily to the initial costs associated with our OSB mill in Alabama and improvements in our hardboard facilities to expand our siding capacities. Additionally, we contributed $9 million to our OSB joint ventures with Canfor Corporation and Abitibi Consolidated for working capital requirements. We also used approximately $3.6 billion to purchase investments with maturities in excess of 90 days and received $3.4 billion on the sale of these types of investments. We received $71 million in proceeds from our notes receivable from asset sales.

Capital expenditures for 2007 are expected to total between $280 to $300 million for new mills under construction, projects to reduce our energy, raw materials and resin costs in our current OSB mills and for expansion projects in our OSB, EWP and siding operations.

FINANCING ACTIVITIES

In the first six months of 2007, net cash provided by financing activities was $14 million. In the first six months of 2007, we borrowed $30 million under a revolving credit facility to support general operating requirements in our Canadian locations and borrowed $13 million under a secured long term credit facility to fund our Chilean expansion. Additionally, in the first six months of 2007, we paid cash dividends of $31 million.

In the first six months of 2006, net cash used in financing activities was $234 million. In the first six months of 2006, we generated $6 million in proceeds from the sale of common stock under our various equity compensation plans, received a tax benefit of $3 million related to these sales and paid cash dividends of $32 million. Additionally, in the first six months of 2006, we repaid $189 million of our debt and repurchased one million shares of stock at a cost of $22 million.

CREDIT FACILITIES

We have a revolving line of credit, expiring in September 2009, which provides for a committed borrowing capacity of $150 million. Subject to the willingness of existing or new lenders under the credit facility to advance additional funds, we may increase our borrowing capacity under the facility by up to an additional $100 million. The facility allows us to cash collateralize the facility, at our option, in order to lower the cost of letters of credit. If cash collateralized, this facility requires LP to pledge, as security for its reimbursement obligations under the facility, cash collateral in an amount equal to 105% of the face amount of the letters of credit outstanding under the facility at any time. At June 30, 2007, we had no borrowings outstanding under the facility. Letters of credit issued and outstanding, which reduce our borrowing capacity, totaled approximately $33.2 million as of June 30, 2007 and were cash collateralized with $34.9 million.

We also have a $10 million (Canadian) line of credit facility in Canada. Our ability to obtain letters of credit under this facility ends in December 2007. The facility allows us to cash collateralize the facility, at our option, in order to lower the cost of such borrowings. If cash collateralized, this facility requires LP to pledge, as security for its reimbursement obligations under the facility, cash collateral in an amount equal to 105% of the face amount of the

letters of credit outstanding under the facility at any time. Letters of credit issued and outstanding totaled approximately $0.8 million as of June 30, 2007 and were cash collateralized with $0.8 million.

We have a $100 million (Canadian or US) credit facility in Canada. The facility allows us to finance general operating requirements. At June 30, 2007, we had $32.6 million outstanding under this facility. This amount is included in LP’s Condensed Consolidated Balance Sheet under the caption “short-term notes payable”.

Louisiana Pacific Chile SA (LP Chile) has a committed term credit facility with a Chilean bank for up to $40 million. LP Chile’s ability to draw from this facility ends in December 2008, with the final maturity in March 2015. The proceeds from the facility are being used to fund construction of an additional OSB plant in Chile. At June 30, 2007, there was $16 million outstanding under this facility. Borrowings under the facility were secured.

The following details our debt ratings as of July 15, 2007:

Senior Notes		Baa3		BBB-

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. However, should the markets for our products deteriorate to 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.

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.

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. Based upon our indebtedness at June 30, 2007, a 100 basis point interest rate change would impact the pre-tax net income and cash flow by $1.3 million annually.

Our international operations have exposure to foreign currency rate risks, primarily due to fluctuations in the Canadian dollar. Although we have in the past entered into foreign exchange contracts associated with certain of our indebtedness and 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 6.5 billion square feet (3/8” basis) or 5.6 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 $5.6 million.

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 June 30, 2007, 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 12 – 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 longer-term interest rates, which in recent years have been at relatively low levels. A significant increase in longer-term interest rates, 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. 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 48% of our sales in the first six months of 2007 and 58% of our sales in 2006 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. We cannot assure you that pricing for OSB or our other products will not decline from current levels.

Increased industry production capacity for OSB could constrain our operating margins for the foreseeable future. According to Resource Information Systems, Inc. (RISI), an industry market research organization, total North American OSB annual production capacity increased by about 6 billion square feet from 2000 to 2006 on a 3/8-inch equivalent basis and is projected to increase by approximately 12 billion square feet in the 2007 to 2011 period. RISI has projected that total North American demand for OSB will increase by about 13 billion square feet during the same 2007 to 2011 period. If increases in OSB production capacity exceed increases in OSB demand, OSB could have constrained operating margins for the foreseeable future.

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

Our results of operations may be harmed by potential shortages of raw materials and increases in raw material costs. The most significant raw material used in our operations is wood fiber. We currently obtain about 63% 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. In addition to wood fiber, we also use a significant quantity of various resins in our manufacturing processes. Resin product costs are influenced by changes in the prices or availability of raw materials used to produce resins, primarily petroleum products, as well as demand for and availability of resin products. Selling prices of our products have not always increased in response to raw material cost increases. We are unable to determine to what extent, if any, we will be able to pass any future raw material cost increases through to our customers through product price increases. Our inability to pass increased costs through to our customers could have a material adverse effect on our financial condition, results of operations and cash flows.

Many of the Canadian forestlands 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.

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. Based on our current operations, we believe our cash flow from operations and other capital resources will be adequate to meet our operating needs, capital expenditures and other cash requirements for the foreseeable future. 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.

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, remediation of hazardous substances or other contaminants and, in the past, 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 and 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 warranty or non-warranty product liability claims and other claims, including claims for wrongful death, personal injury and property damage alleged to have arisen out of the use or 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.

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, goodwill, 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. 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 strengthening of the Canadian dollar or the Chilean Peso relative to the U.S. dollar may have a material adverse effect on our financial condition and results of operations.
