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 us and our 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 consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2017.
NOTE 2 - NEW ACCOUNTING STANDARDS AND CERTAIN RECLASSIFICATIONS
On January 1, 2018, we adopted ASU 2014-09, "Revenue from Contracts with Customers" (ASC 606), and all the related amendments to all contracts using the modified retrospective method. We recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. We expect the impact of the adoption of the new revenue standard to be immaterial to our net income on an ongoing basis. Recognition of a portion of our sales revenue has been delayed due to the timing of satisfying the performance obligations. The new revenue standard also provided additional clarity that resulted in reclassifications to or from net sales and selling, general and administrative expenses.
On January 1, 2018, we adopted ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The guidance allows us to reclassify the stranded tax effects within Accumulated other comprehensive income to Retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (the Tax Act) is recorded.
The cumulative effect of the changes made to our Consolidated Balance Sheet as of January 1, 2018 for the adoption of ASU 2014-09 and ASU 2018-02 is as follows:

Dollar amounts in millions | Balance at December 31, 2017 |  | ASU 2014-09 |  | ASU 2018-02 |  | Balance at January 1, 2018
Receivables, net of allowance for doubtful accounts | $ | 142.5 |  |  | $ | (21.7 | ) |  | $ | — |  |  | $ | 120.8 |
Inventories | 259.1 |  |  | 15.8 |  |  | — |  |  | 274.9 |
Deferred tax asset | 2.5 |  |  | 1.5 |  |  | — |  |  | 4.0 |
Retained earnings | 1,280.1 |  |  | (4.4 | ) |  | 16.7 |  |  | 1,292.4 |
Accumulated comprehensive loss | (122.1 | ) |  | — |  |  | (16.7 | ) |  | (138.8 | )

On January 1, 2018, we adopted ASU 2017-07, "Retirement Benefits - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" (an amendment to ASC 715), to improve the presentation of net periodic pension and postretirement benefit costs. We retrospectively adopted the presentation of service cost separate from the other components of net periodic costs. The interest cost, expected return on assets, amortization of prior service costs, amortization of net actuarial losses and settlement costs have been reclassified from Cost of sales, Selling, general and administrative expenses and Other operating credits and charges to Non-operating income (expense). We elected to apply the practical expedient which allows us to reclassify amounts disclosed previously in the retirement benefits note as the basis for applying retrospective presentation for comparative periods as it is impracticable to determine the disaggregation of the cost components for amounts capitalized and amortized in those periods. On a prospective basis, the other components of net periodic benefit costs (excluding service cost) will not be included in amounts capitalized in inventory or property, plant, and equipment. In addition to the effects of ASU 2017-07, we have reclassified depreciation and amortization into the financial statement caption that reflects the category of the expense to be more comparable with our peers.
The effect of the retrospective presentation change related to the net periodic cost of our defined benefit pension and reclassification of depreciation and amortization on our Consolidated Statement of Income for the quarter and nine months ended September 30, 2017 is as follows:

On January 1, 2018, we adopted ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash." The adoption of this standard requires the inclusion of the change in amounts described as restricted cash or restricted cash equivalents to be included as part of our Consolidated Statement of Cash Flows.
In accordance with disclosure requirements of this new accounting standard, the impact of adoption on our Consolidated Statement of Cash Flows for the quarter and nine months ended September 30, 2017 is as follows:

In March 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-02, "Leases (Topic 842)", which supersedes the lease accounting requirements in ASC Topic 840, "Leases". The new standard requires entities to recognize, separately from each other, an asset for its right to use (ROU) the underlying asset equal to the liability for its finance and operating lease obligations. Further, the entity is required to present separately the current and non-current portion of the ROU asset and corresponding lease liability. In July 2018, the FASB issued ASU 2018-10, "Codification Improvements to Topic 842, Leases", which clarifies certain aspects of the new lease standard. The amendments in this ASU address the rate implicit in the lease, impairment of the net investment in the lease, lessee reassessment of lease classification, lessor reassessment of lease term and purchase options, variable payments that depend on an index or rate and certain transition adjustments, among other things. In July 2018, the FASB issued ASU 2018-11, "Leases (Topic 842)" Targeted Improvements, which provides an additional (and optional) transition method whereby the new lease standard is applied at the adoption date and recognized as an
10

adjustment to retained earnings. The amendments have the same effective date and transition requirements as the new lease standard. We will adopt the standard on January 1, 2019 using this optional transition method. The adoption of the new standard will result in a significant increase to our balance sheet for lease liabilities and right-of-use assets. The extent of the increase to assets and liabilities associated with these amounts remains to be determined pending our completion of the review of existing lease contracts. We are in the process of implementing a new system, collecting data and designing processes and controls to account for our leases in accordance with the new standard.
In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement: Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement", which amends the fair value measurement disclosure requirements of ASC 820. The amended guidance modifies the disclosure requirements of assets and liabilities measured at fair value by removing and adding certain disclosures for these measurements. The eliminated disclosures include the valuation processes for Level 3 fair value measurements. Additional disclosures include the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The new standard is effective for fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted. The adoption of this guidance will modify our disclosures but will not have a material effect on our consolidated financial statements.
In August 2018, the FASB issued ASU 2018-14, "Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans", which amends ASC 715 to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The amended guidance modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated Other Comprehensive Income (OCI) expected to be recognized in net periodic benefit costs over the next fiscal year, and (b) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for post-retirement health care benefits. Additional disclosures include descriptions of significant gains and losses affecting the benefit obligation for the period. The amended guidance is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The adoption of this guidance will modify our disclosures but will not have a material effect on our consolidated financial statements.
In August 2018, the FASB issued ASU 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract", which provides additional guidance on the accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. The amendments require an entity in such arrangements to account for implementation costs in the same manner as internal-use software as outlined in ASC 350. The amended guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact, that the adoption of this guidance will have on our financial statements and related disclosures.
NOTE 3 - REVENUE
Revenue is recognized when obligations under the terms of a contract (purchase orders) with our customers are satisfied; generally, this occurs with the transfer of control of our products. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. Shipping cost incurred by us to deliver products to our customers are recorded in cost of sales. The expected costs associated with our warranties continue to be recognized as expense when the products are sold. We recognize revenue as of a point in time.
Customer programs and incentives are a common practice in our businesses. Our businesses incur customer program costs to obtain favorable product placement, to promote sales of products and to maintain competitive pricing. Customer program costs and incentives, including rebates and promotion and volume allowances, are accounted for as deductions from net sales at the time the program is initiated. These reductions from revenue are recorded at the later of the time of sale or the implementation of the program based on management’s best estimates. Estimates are based on historical and projected experience for each type of program or customer. Volume allowances are accrued based on management’s estimates of customer volume achievement and other factors incorporated into customer agreements, such as new product purchases, store sell-through and merchandising support. Management periodically reviews accruals for these rebates and allowances, and adjusts accruals when circumstances indicate (typically as a
11

result of a change in volume expectations). As of September 30, 2018 and December 31, 2017, we had $27.5 million and $24.2 million accrued as customer rebates recorded in Accounts payable and accrued liabilities on our Consolidated Balance Sheets.
We ship some of our products to customers' distribution centers on a consignment basis. We retain title to our products stored at the distribution centers. As our products are removed from the distribution centers by retailers and shipped to retailers’ stores, title passes from us to the retailers. At that time, we invoice the retailers and recognize revenue for these consignment transactions. We do not offer a right of return for products shipped to the retailers’ stores from the distribution centers. The amount of consignment inventory as of September 30, 2018 and December 31, 2017 was $18.2 million and $18.3 million.

NOTE 4 - STOCK-BASED COMPENSATION
We have a Management Incentive Plan (MIP) that is administered by the Compensation Committee of the Board of Directors. The Compensation Committee authorizes the grants of restricted stock (shares or units), performance share awards payable in stock based upon the attainment of specified performance goals and stock settled stock appreciation rights (SSARs). As of September 30, 2018, 2.9 million shares were available for grant under the 2013 Omnibus Plan.

NOTE 5 – FAIR VALUE MEASUREMENTS
We estimated our Senior Notes due in 2024 to have a fair value of $350.2 million at September 30, 2018 and $363.9 million at December 31, 2017 based upon market quotations.
Carrying amounts reported on the balance sheet for cash and cash equivalents, accounts receivables, accounts payable and current portion of long-term debt approximate fair value due to the short-term maturity of these items.
NOTE 6 – EARNINGS PER SHARE
Basic earnings per share are based upon 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. Our potentially dilutive securities consist of restricted stock, restricted stock units, performance share awards and SSARs.

NOTE 9 - INVESTMENTS IN AND ADVANCES TO AFFILIATES
During the second quarter of 2018, we invested $45.0 million in Entekra Holdings, LLC (Entekra), a start-up design, engineering and manufacturing company that provides off-site framing for both residential and commercial construction. This investment is recorded as an equity investment based upon the joint control of Entekra’s operations. We own 81.8% of the A units and 55% of the B units of this operation. Our portion of the earnings and losses of Entekra is included in our Consolidated Statement of Income as Income (loss) from unconsolidated affiliate.
At September 30, 2018, we have an investment in a joint venture with Resolute Forest Products to operate jointly owned I-Joist facilities in Quebec. We are the exclusive distributor of the I-joists produced and sold by the joint venture and these operations are considered an integral part of our operations. Our portion of the earnings and losses of these operations are classified as a reduction in cost of sales.
NOTE 10 – 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 basis of assets and liabilities. This method also requires the recognition of future tax benefits, 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, considering the future reversal of existing deferred tax liabilities 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 period, 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. Changes in the profitability estimates in various jurisdictions will impact our quarterly effective income tax rates.
The Tax Act reduced the U.S. federal tax rate from 35% in 2017 to 21% in 2018 and eliminated the deduction for Domestic Production Activities. We estimate that these changes will result in a reduction of approximately 7% in our overall effective tax rate for 2018.
For the first nine months of 2018, the primary differences between the U.S. statutory rate of 21% and the 24% effective rate applicable to our income from continuing operations relate to state income tax, discretionary pension payments, foreign tax rates and tax deductions related to stock-based compensation. For the first nine months of 2017, the primary differences between the U.S. statutory rate of 35% and the 27% effective rate applicable to our continuing operations relate to foreign tax rates, changes in Canadian valuation allowances, and the deduction for U.S. Domestic Production Activities.
16

During the second quarter of 2017, we deposited $32.0 million with U.S. I.R.S. to suspend the running of interest on potential underpayments of disputable income tax amounts for the year 2016.
We periodically review the need for valuation allowances against deferred tax assets and recognize these deferred tax assets to the extent that the realization is more likely than not. As part of our review, we consider all positive and negative evidence, including earnings history, the future reversal of deferred tax liabilities, and the relevant expirations of carryforwards. We believe the valuation allowances provided are appropriate. If in future periods our earnings estimates differ from the estimates used to establish these valuation allowances, or other objective positive or negative evidence arises, we may be required to record an adjustment resulting in an impact on tax expense (benefit) for that period.
At the end of 2017, we recorded a provisional benefit of $18.4 million resulting from the reduction in the carrying value of our U.S. deferred tax liabilities to reflect the change in the U.S. corporate income tax rate from 35% to 21% under the Tax Act. During the first nine months of 2018, we revised our estimate of the amount of deferred taxes related to discretionary pension contributions, and recorded an additional benefit of $3.1 million as a discrete item in the second quarter.
Our accounting of other elements of the Tax Act is complete and there were no adjustments to the provisional amounts previously recorded.

During the third quarter of 2018, we recorded a gain of $7.7 million related to the reduction in product-related warranty reserves associated with CanExel products sold in specific geographic locations and for a specific time period based upon reductions in claims activities. Additionally, we recorded $0.9 million in severance and other charges related to certain reorganizations and a loss of $0.5 million related to property damage sustained by our Wilmington facility during the recent hurricane.
During the first nine months of 2018 in addition to the above, we recorded a gain of $8.3 million related to the settlement of previously-paid environmental costs or the liability for future environmental costs to be paid by a third party associated with a non-operating site, $3.8 million in severance and other charges related to certain reorganizations within the corporate offices, including the costs associated with the retirement of our previous chief financial officer and a gain of $0.4 million related to a previously-settled claim associated with our hardboard siding.
During the third quarter of 2017, we recorded a refund of $0.9 million related to sales and use taxes.
During the first nine months of 2017 in addition to the above, we recorded an increase of $5.4 million related to product-related warranty reserves associated with CanExel products sold in specific geographic locations and for a specific time period based upon increases in claims activities.
NOTE 12 – LEGAL AND ENVIRONMENTAL MATTERS
Certain environmental matters and legal proceedings are discussed below.
17

Environmental Matters
We maintain 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. Our estimates of our environmental loss contingencies are based on various assumptions and judgments, the specific nature of which varies in light of the particular facts and circumstances surrounding each environmental loss contingency. These estimates typically reflect assumptions and judgments as to the probable nature, magnitude and timing of required investigation, remediation and/or monitoring activities and the probable cost of these activities, and in some cases reflect assumptions and judgments as to the obligation or willingness and ability of third parties to bear a proportionate or allocated share of the cost of these activities. Due to the numerous uncertainties and variables associated with these assumptions and judgments, and the effects of changes in governmental regulation and environmental technologies, both the precision and reliability of the resulting estimates of the related contingencies are subject to substantial uncertainties. We regularly monitor our estimated exposure to environmental 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.
The activity in our reserve for estimated environmental loss contingency reserves for the quarter and nine months ended September 30, 2018 and 2017 is summarized in the following table.

| Quarter Ended |  | Nine Months Ended

Other Proceedings
We and our subsidiaries are parties to other legal proceedings. Based on the information currently available, management believes the resolution of such proceedings will not have a material adverse effect on our financial position, results of operations, cash flows or liquidity.
NOTE 13 – SELECTED SEGMENT DATA
We operate in four segments: Siding, OSB, EWP and South America. Our business units have been aggregated into these four segments based upon the similarity of economic characteristics, customers and distribution methods. Our 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 our Annual Report on Form 10-K for the year ended December 31, 2017.

NOTE 14 – POTENTIAL IMPAIRMENTS
We continue to review certain operations and investments for potential impairments. We currently believe we have 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.
We also review 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, we may be required to record impairment charges in connection with decisions to dispose of assets.
19

NOTE 15 – PRODUCT WARRANTY
We provide warranties on the sale of most of our products and record 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 quarter and nine months ended September 30, 2018 and 2017 are summarized in the following table:

| Quarter Ended |  | Nine Months Ended

We continue to monitor warranty and other claims associated with these products and believe as of September 30, 2018 that the reserves associated with these matters are adequate. However, it is possible that additional changes 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 Other long-term liabilities on our Consolidated Balance Sheets.

During the nine months ended September 30, 2018, we made $40.9 million in pension contributions to our defined benefit pension plans, which included a discretionary payment of $33.2 million to maximize the tax savings allowed under the Tax Cuts and Jobs Act and to lower our expenses associated with pension funding regulations going forward. We expect to contribute about $3.0 million to our defined benefit pension plans in the remaining months of 2018.
NOTE 18 - DISCONTINUED OPERATIONS
LP has adopted and implemented plans to sell selected businesses and assets in order to improve its operating results. For all periods presented, these operations include residual losses of mills divested in past years and associated warranty and other liabilities associated with these operations.

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

GENERAL
LP is a leading building products solutions company that manufactures sustainable, quality engineered wood building materials including siding, oriented strand board and engineered wood products. Our products are used primarily in new home construction, repair and remodeling, and outdoor structures. We also market and sell our products in light industrial and commercial construction and we have a modest export business. Our manufacturing facilities are primarily located in the U.S. and Canada, but we also operate two facilities in Chile and one facility in Brazil.
To serve these markets, we operate in four segments: Siding; North America Oriented Strand Board (OSB); Engineered Wood Products (EWP); and South America.
Demand for our products correlates to a significant degree to the level of new home construction activity in North America, which historically has been characterized by significant cyclicality. The U.S. Department of Census reported that U.S. single and multi-family housing starts were 4% higher than for the third quarter and 7% higher for the first nine months of 2018 as compared to the same periods of 2017.
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 OSB products will remain at current levels or increase or decrease in the future. OSB prices (NC 7/16"), as reported by Random Lengths, were 8% lower for the third quarter and 13% higher for the first nine months of 2018 compared to the same periods in 2017.
For additional factors affecting our results, refer to the Management Discussion and Analysis of Financial Condition and Results of Operations overview contained in our Annual Report on Form 10-K for the year ended December 31, 2017 and to “About Forward-Looking Statements” and “Risk Factors” in this report.
EXECUTIVE SUMMARY
We recorded a 3% increase in sales to $736.8 million for the quarter ended September 30, 2018 from $718.3 million reported for the quarter ended September 30, 2017. We recorded income from continuing operations of $124.1 million for the quarter ended September 30, 2018 compared to $110.9 million for the quarter ended September 30, 2017. We recorded net income of $124.0 million ($0.86 per diluted share) for the quarter ended September 30, 2018 compared to $109.8 million ($0.75 per diluted share) for the quarter ended September 30, 2017. We reported a decrease of $1.0 million in Adjusted EBITDA from continuing operations for the third quarter of 2018 as compared to the third quarter of 2017. Declines in OSB pricing in all North American operations had a negative impact on our operating results of $5.0 million for the quarter ended September 30, 2018 as compared to the quarter ended September 30, 2017.
We recorded an 11% increase in sales to $2.2 billion for the nine months ended September 30, 2018 from $2.0 billion reported for the nine months ended September 30, 2017. We recorded income from continuing operations of $381.9 million for the nine months ended September 30, 2018 compared to $260.3 million for the nine months ended September 30, 2017. We recorded net income of $377.6 million ($2.59 per diluted share) for the nine months ended September 30, 2018 compared to $259.2 million ($1.77 per diluted share) for the nine months ended September 30, 2017. We reported an increase of $119.8 million in Adjusted EBITDA from continuing operations for the nine months ended of 2018 as compared to the first nine months of 2017. Improvements in OSB pricing in all North American operations had a positive impact on our operating results of $128.3 million for the nine months ended September 30, 2018 as compared to the nine months ended September 30, 2017.
These changes are discussed further in "Our Operating Results" below.
CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ESTIMATES
Presented in Note 1 of the Notes to the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2017 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 2018, these significant accounting estimates and judgments include:
24

Long-lived Assets
Long-lived assets (including amortizable identifiable intangible assets) or asset group held for use is tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. When such events occur, we compare the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of a long-lived asset or asset group. The cash flows are based on our best estimate of future cash flows derived from the most recent business projections. If this comparison indicates that there is an impairment, the amount of the impairment is calculated based on fair value. Fair value is estimated primarily using discounted expected future cash flows on a market-participant basis.
Defined Benefit Plans
We have a number of pension plans in the U.S. and Canada, covering many of the Company’s employees. Benefit accruals under our defined benefit pension plan in the U.S. were frozen as of January 1, 2010.
We account for the consequences of our sponsorship of these plans based upon assumptions that are used to calculate the related assets, liabilities and expenses recorded in our financial statements. Net actuarial gains and losses occur when actual experience differs from any of the assumptions used to value defined benefit plans or when assumptions change as they may each year. The primary factors contributing to actuarial gains and losses are changes in the discount rate used to value obligations as of the measurement date and the differences between expected and actual returns on pension plan assets. This accounting method results in the potential for volatile and difficult to forecast gains and losses.
We record amounts relating to these defined benefit plans based on various actuarial assumptions, including discount rates, assumed rates of return, compensation increases and life expectancy. We review our actuarial assumptions on an annual basis and make modifications to the assumptions based on current economic conditions and trends. We believe that the assumptions utilized in recording our obligations under our plans are reasonable based on our experience and on advice from our independent actuaries; however, differences in actual experience or changes in the assumptions may materially affect our financial condition or results of operations.
Income Taxes
We establish deferred tax liabilities or assets for temporary differences between financial and tax reporting bases and subsequently adjust them to reflect changes in tax rates expected to be in effect when the temporary differences reverse. We record a valuation allowance reducing deferred tax assets when it is more likely than not that such assets will not be realized.
We record liabilities for uncertain income tax positions based on a two-step process. The first step is recognition, where we evaluate whether an individual tax position has a likelihood of greater than 50% of being sustained upon examination based on the technical merits of the position, including resolution of any related appeals or litigation processes. For tax positions that are currently estimated to have a less than 50% likelihood of being sustained, no tax benefit is recorded. For tax positions that have met the recognition threshold in the first step, we perform the second step of measuring the benefit (expense) to be recorded. The actual benefits (expense) ultimately realized may differ from our estimates. In future periods, changes in facts, circumstances, and new information may require us to change the recognition and measurement estimates with regard to individual tax positions. Changes in recognition and measurement estimates are recorded in the consolidated statement of income and consolidated balance sheet in the period in which such changes occur. As of September 30, 2018 and December 31, 2017, we had liabilities for unrecognized tax benefits (including interest) pertaining to uncertain tax positions totaling $43.0 million and $42.3 million.
Customer Program Costs
25

Customer programs and incentives are a common practice in our businesses. Our businesses incur customer program costs to obtain favorable product placement, to promote sales of products and to maintain competitive pricing. Customer program costs and incentives, including rebates and promotion and volume allowances, are accounted for in either sales or the category selling and administrative expenses at the time the program is initiated and/or the revenue is recognized. The costs are predominantly recognized in sales and include, but are not limited to, volume allowances and rebates, promotional allowances, and cooperative advertising programs. These costs are recorded at the later of the time of sale or the implementation of the program based on management’s best estimates. Estimates are based on historical and projected experience for each type of program or customer. Volume allowances are accrued based on management’s estimates of customer volume achievement and other factors incorporated into customer agreements, such as new products, store sell-through, merchandising support and customer training. Management periodically reviews accruals for these rebates and allowances, and adjusts accruals when circumstances indicate (typically as a result of a change in volume expectations). As of September 30, 2018 and December 31, 2017, we had $27.5 million and $24.2 million accrued as customer rebates.
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, we disclose segment 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 segment EBITDA from continuing operations (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 credits and charges, net, investment income and other non-operating items. We also disclose adjusted income from continuing operations which excludes (gain) loss on sale or impairment of long-lived assets, other operating credits and charges, net and adjusts for a normalized tax rate. Neither EBITDA from continuing operations, Adjusted EBITDA from continuing operations nor adjusted income from continuing operations are a substitute for the GAAP measure of net income or for any other GAAP measures of operating performance.
We have included EBITDA from continuing operations and Adjusted EBITDA from continuing operations in this report because we use them as important supplemental measures of our performance and believe 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 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 expense and depreciation and amortization which are necessary to operate our business or which we otherwise incur or experience in connection with the operation of our business.
We believe adjusted income from continuing operations, which excludes (gain) loss on sale or impairment of long-lived assets and other operating credits and charges, net, adjusted for a normalized tax rate is a useful measure for evaluating our ability to generate earnings and that providing this measure will allow investors to more readily compare the earnings for past and future periods. It should be noted that other companies may present similarly-titled measures differently and, therefore, as presented by us may not be comparable to similarly-titled measures reported by other companies. In addition, adjusted income from continuing operations has material limitations as a performance measure because it excludes items that are actually incurred or experienced in connection with the operations of our business.

OSB | (11 | )% |  | (24 | )% |  | 16 | % |  | (10 | )%

For the quarter and nine months ended September 30, 2018 compared to the corresponding periods in 2017, sales volumes increased in our SmartSide strand product line due to increased market penetration in key markets. Sales prices in our SmartSide strand product line for the quarter and nine months ended September 30, 2018 as compared to the corresponding periods in 2017 were higher due to price increases which were implemented in the first quarter of 2018 and the second quarter of 2017.
For the quarter and nine months ended September 30, 2018 compared to the corresponding periods in 2017, sales volumes declined in our SmartSide fiber product line due to our decision to raise prices which slowed demand. Sales prices in our SmartSide fiber product line for the quarter and nine months ended September 30, 2018 as compared to the corresponding periods in 2017 were higher due to a price increase implemented in the first quarter of 2018.
For CanExel, sales volumes decreased in the third quarter and first nine months of 2018 as compared to the corresponding periods in 2017 due to decreased demand in Canada due to customers re-balancing their inventories. Sales prices changed for the third quarter and first nine months of 2018 as compared to the corresponding periods in 2017 due to changes in our product mix and the fluctuations in the U.S. to Canadian dollar as a majority of these sales are denominated in Canadian dollars.
For our OSB produced in the siding segment for the quarter and nine months ended September 30, 2018 compared to the corresponding periods in 2017, sales prices changed, as discussed in the OSB segment below. Sales volumes were lower for the quarter and nine months ended September 30, 2018 compared to the corresponding periods in 2017 due to logistics challenges. We estimated Adjusted EBITDA from continuing operations associated with OSB produced and sold in the siding segment for the quarter and nine months ended September 30, 2018 was $4.5 million and $19.6 million as compared to the comparable periods in 2017 of $8.5 million and $14.9 million.
Overall, the improvement in the siding segment for the third quarter and first nine months of 2018 compared to the same periods of 2017 was due to higher pricing and volume on our SmartSide strand products which were partially offset by increases in raw materials, primarily resin, expenses associated with the Dawson Creek conversion project, logistic challenges resulting in higher freight and lower throughput, principally at our Dawson Creek mill and increases in sales and marketing expenses.

OSB - value-add | 3 | % |  | 8 | % |  | 13 | % |  | 1 | %

For the quarter ended September 30, 2018, OSB prices decreased compared to the corresponding period in 2017 and increased for the nine months ended September 30, 2018 compared to the corresponding periods in 2017 likely due to the overall demand compared to the supply available in the market.
Sales volumes for the quarter ended and nine months ended September 30, 2018 are higher in value-add and lower in commodity compared to the corresponding periods of 2017 due to our continued expansion of our value added footprint.
The decrease in selling price negatively impacted operating results and Adjusted EBITDA from continuing operations by $3.8 million for the quarter ended September 30, 2018 as compared to the same period in 2017. The increase in selling price positively impacted operating results and Adjusted EBITDA by $117.4 million for the nine months ended September 30, 2018 as compared to the same period in 2017.
Overall the decline in our OSB segment results for the quarter ended September 30, 2018 as compared to the same period in 2017 was due to decreased sales prices and increases in raw material costs (primarily resin). Overall, the improvements in our OSB segment results for nine months ended September 30, 2018 as compared to the same period in 2017 was due to increased sales prices partially offset by increases in raw material costs (primarily resin) and increases in manufacturing costs due to downtime related to logistics associated with our Western Canadian operations and maintenance capital improvements.

GENERAL CORPORATE AND OTHER EXPENSE, NET
General corporate expenses were 5% lower for the the quarter and 2% lower for the nine months ended September 30, 2018 compared to the same periods in 2017. The decrease in costs are associated with changes in our incentive compensation plans and lower stock compensation expense offset by higher corporate initiatives related to supply chain activities. General corporate and other expenses primarily consist of corporate overhead such as wages and benefits, professional fees, insurance and other expenses for corporate functions including certain executive officers, public company costs, information technology, financial services, environmental and safety, legal, supply management, human resources and other corporate functions.

INCOME TAXES
For the first nine months of 2018, we recorded an income tax expense on continuing operations of 24% as compared to 27% in the comparable period of 2017. The primary differences between the U.S. statutory rate of 21% and the effective rate of 24% applicable to our income from continuing operations for the first nine months of 2018 relate to state income tax, foreign tax rates, discretionary pension payments and tax deductions related to stock-based compensation. For the first nine months of 2017, the primary differences between the U.S. statutory rate of 35% and the effective rate of 27% applied to our continuing operations relate to foreign tax rates, changes in Canadian valuation allowances and the deduction for U.S. domestic production activities.
Each quarter the income tax accrual is adjusted to the latest estimate and the difference from the previously accrued year-to-date balance is recorded in the current quarter.
OTHER COMPREHENSIVE INCOME (LOSS)
During the first nine months of 2018, the strengthening of the U.S. dollar as compared to the functional currencies of our South American operations resulted in a loss on foreign currency adjustment in other comprehensive income of $13.5 million as compared to income of $4.7 million during the comparable period of 2017. During the first nine months of 2018, the Brazilian real and Chilean peso weakened 18% and 6% as compared to the U.S. dollar.

Our principal uses of liquidity are paying the costs and expenses associated with our operations, servicing outstanding indebtedness, paying dividends and making capital expenditures. We may also from time to time prepay or repurchase outstanding indebtedness, repurchase common stock or acquire assets or businesses that are complementary to our operations. Any such repurchases may be commenced, suspended, discontinued or resumed, and the method or methods of effecting any such repurchases may be changed, at any time or from time to time without prior notice.
OPERATING ACTIVITIES
During the first nine months of 2018, operating activities provided $419.2 million of cash compared to $305.0 million during the first nine months of 2017. This change was primarily related to improvements in operating results (higher OSB pricing and SmartSide strand volume) offset by increases in working capital. In the third quarter of 2018, we made a discretionary contribution to our defined benefit pension plan of $33.2 million to maximize the tax savings allowed under the Tax Cuts and Jobs Act and lower our expenses associated with pension funding regulations going forward.
INVESTING ACTIVITIES
During the first nine months of 2018, cash used in investing activities was approximately $172.7 million. Capital expenditures in the first nine months of 2018 were $150.4 million. We used $45.0 million to invest in an unconsolidated affiliate (see Note 9 for additional details). Additionally, we received a payment of $22.2 million on notes receivable from asset sales. Included in “Accounts payable” is $17.1 million related to capital expenditures that had not yet been paid as of September 30, 2018.
During the first nine months of 2017, cash used in investing activities was approximately $109.1 million. Capital expenditures in the first nine months of 2017 were $80.7 million. We used $32.0 million to deposit cash with the U.S. I.R.S to suspend the running of interest on potential underpayments of disputable income tax amounts for the year 2016. Included in “Accounts payable” was $8.2 million related to capital expenditures that had not yet been paid as of September 30, 2017.
Capital expenditures in 2018 are expected to be approximately $200 million to $225 million related to expansions in our siding business, growth and maintenance projects and our South American expansion.
FINANCING ACTIVITIES
During the first nine months of 2018, cash used in financing activities was $183.3 million. We used $56.1 million to pay cash dividends, $108.0 million to repurchase stock either though a share repurchase program or in connection with income tax withholding requirements associated with our employee stock-based compensation plans. Additionally, during the first nine months of 2018, we received a grant from the Investments in Forest Industry Transformation program in Canada for $3.1 million in connection with our conversion of the Dawson Creek OSB mill.
During the first nine months of 2017, cash used in financing activities was $8.2 million. We used $2.5 million to repay outstanding debt in the first nine months of 2017 and $5.3 million to repurchase stock from employees in connection with income tax withholding requirements associated with our employee stock-based compensation plans.

POTENTIAL IMPAIRMENTS
We continue to review 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, 2018, the fair value of facilities that have not been indefinitely curtailed was in excess of their carrying value and supports the conclusion that no impairment is necessary for those facilities.
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

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 of 4.9 billion square feet (3/8" basis) or 4.2 billion square feet (7/16" basis), a $1 change in the annual average price per thousand square feet on 7/16" basis would change annual pre-tax profits by approximately $4.2 million.
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
As of September 30, 2018, our Chief Executive Officer and Interim Chief Financial Officer have carried out, with the participation of the Company's Disclosure Practices Committee and the Company'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 of 1934 (the Act). Based upon this evaluation, the Chief Executive Officer and Interim 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 Interim Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control Over Financial Reporting
We had no changes in our internal control over financial reporting during the quarter ended September 30, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
