NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1. NATURE OF OPERATIONS AND BASIS FOR PRESENTATION
Nature of Operations
Louisiana-Pacific Corporation and our subsidiaries is a leading provider of high-performance building solutions that meet the demands of builders, remodelers, and homeowners worldwide. We have leveraged our expertise serving the new home construction, repair and remodeling, and outdoor structures markets to become an industry leader known for innovation, quality, and reliability. In addition to our U.S. operations, the Company also maintains manufacturing facilities in Canada, Chile, and Brazil through foreign subsidiaries, and operates facilities through joint ventures. The principal customers for our building solutions are retailers, wholesalers, and homebuilding and industrial businesses in North America and South America, with limited sales to Asia, Australia, and Europe. References to "LP," "the Company," "we," "our," and "us" refer to Louisiana-Pacific Corporation and its consolidated subsidiaries as a whole.
Basis for Presentation
The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) for interim financial information. Accordingly, they do not include all the information and footnotes required by U.S. GAAP for complete consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal and recurring nature. These Condensed Consolidated Financial Statements and Notes hereto should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on February 18, 2021 (2020 Annual Report on Form 10-K). Results of operations for interim periods are not necessarily indicative of results to be expected for an entire year. All dollar amounts are shown in millions except per share.
Recently Adopted Accounting Policies
In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). This ASU simplifies the accounting for income taxes by, among other things, eliminating certain existing exceptions related to the general approach in ASC 740 relating to franchise taxes, reducing complexity in the interim-period accounting for year-to-date loss limitations and changes in tax laws, and clarifying the accounting for transactions outside of business combinations that result in a step-up in the tax basis of goodwill. The Company adopted ASU 2019-12 effective as of January 1, 2021. There was no impact on our Condensed Consolidated Financial Statements upon adoption.
NOTE 2. REVENUE
The following table presents our reportable segment revenues, disaggregated by revenue source. We disaggregate revenue from contracts with customers into major product lines. We have determined that disaggregating revenue into these categories achieves the disclosure objective to depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors.
As noted in the segment reporting information in Note 18 below, our reportable segments are Siding, Oriented Strand Board (OSB), Engineered Wood Products (EWP), and South America.

Revenue is recognized when obligations under the terms of a contract (i.e., purchase orders) with our customers are satisfied; generally, this occurs with the transfer of control of our products at a point in time. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. The shipping cost incurred by us to deliver products to our customers is recorded in cost of sales. The expected costs associated with our warranties continue to be recognized as an expense when the products are sold.
12

Our businesses routinely 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 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 adjusts accruals when circumstances indicate (typically as a result of a change in volume expectations).
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.
NOTE 3. EARNINGS PER SHARE
Basic earnings per share is based upon the weighted-average number of shares of common stock outstanding. Diluted earnings per share is based upon the weighted-average number of shares of common stock outstanding, plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. This method requires that the effect of potentially dilutive common stock equivalents (stock options, stock-settled appreciation rights (SSARs), restricted stock units, and performance stock units) be excluded from the calculation of diluted earnings per share for the periods in which losses are reported because the effect is anti-dilutive.
The following table sets forth the computation of basic and diluted earnings per share (in millions, except per share amounts):

| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2021 |  | 2020 |  | 2021 |  | 2020
Net income attributed to LP |  |  |  |  |  |  |
Weighted average common shares outstanding - basic | 94 |  |  | 112 |  |  | 100 |  |  | 112 |
Dilutive effect of employee stock plans | — |  |  | 1 |  |  | 1 |  |  | 1 |
Shares used for diluted earnings per share | 94 |  |  | 113 |  |  | 101 |  |  | 113 |
Earnings per share: |  |  |  |  |  |  |
Basic earnings | $ | 3.90 |  |  | $ | 1.58 |  |  | $ | 11.81 |  |  | $ | 2.16 |
Diluted earnings | $ | 3.87 |  |  | $ | 1.57 |  |  | $ | 11.73 |  |  | $ | 2.15 |

NOTE 4. FAIR VALUE MEASUREMENTS
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. We are required to classify these financial assets and liabilities into two groups: (i) recurring—measured on a periodic basis, and (ii) non-recurring—measured on an as-needed basis.
13

Trading securities consist of rabbi trust financial assets, which are recorded in Other assets in our Condensed Consolidated Balance Sheets. The assets of the rabbi trust are invested in mutual funds and are reported at fair value based on active market quotations, which represent Level 1 inputs. The assets of the rabbi trust were $6 million and $5 million at September 30, 2021, and December 31, 2020, respectively.
The fair value of the 3.625% Senior Notes due in 2029 (2029 Senior Notes) is estimated to be $354 million as of September 30, 2021, based upon market quotations. The 2029 Senior Notes and other long-term debt are categorized as Level 1 in the U.S. GAAP fair value hierarchy. Fair values are based on trading activity among the Company’s lenders and the average bid and ask price as determined using published rates.
There were no outstanding amounts borrowed under our Amended Credit Facility as of September 30, 2021.
During the nine months ended September 30, 2020, we sold our auction rate securities (ARS) and recognized a $3 million gain on available for sale securities, which is included in Investment income in the Condensed Consolidated Statements of Income.
Carrying amounts reported on the balance sheet for cash and cash equivalents, accounts receivables, and accounts payable approximate fair value due to the short-term maturity of these items.
NOTE 5. RECEIVABLES
Receivables consisted of the following:

| September 30, 2021 |  | December 31, 2020
Trade receivables | $ | 211 |  |  | $ | 161 |
Income tax receivable | 11 |  |  | 2 |
Other receivables | 27 |  |  | 23 |
Allowance for doubtful accounts | (2) |  |  | (2) |
Total | $ | 248 |  |  | $ | 184 |

Trade receivables are primarily generated by sales of our products to our wholesale and retail customers. Other receivables, as of September 30, 2021, and December 31, 2020, primarily consist of sales tax receivables, vendor rebates, a receivable associated with an affiliate, and other miscellaneous receivables.
NOTE 6. INVENTORIES
Inventories are valued at the lower of cost or net realizable value. Inventory cost includes materials, labor, and operating overhead. The major types of inventories are as follows (work in process is not material and is included in Semi-finished inventory below):

| September 30, 2021 |  | December 31, 2020
Logs | $ | 47 |  |  | $ | 49 |

NOTE 7. GOODWILL AND OTHER INTANGIBLES
Goodwill and indefinite-lived intangible assets are not amortized and are subject to assessment for impairment by applying a fair value based test on an annual basis or more frequently, if circumstances indicate a potential impairment. The Company’s annual assessment date is October 1.
Changes in goodwill and other intangible assets as of September 30, 2021, are provided in the following table:

| Timber licenses 1 | Goodwill | Developed Technology | Trademarks
Beginning balance December 31, 2020 | $ | 34 |  | $ | 25 |  | $ | 19 |  | $ | 3 |
Amortization | (2) |  | — |  | (1) |  | — |
Ending balance September 30, 2021 | $ | 32 |  | $ | 25 |  | $ | 17 |  | $ | 2 |

1 Timber licenses are included in Timber and timberlands on the Condensed Consolidated Balance Sheets.
NOTE 8. REDEEMABLE NONCONTROLLING INTEREST
Redeemable noncontrolling interest is interest in subsidiaries that is redeemable outside of our control either for cash or other assets. These interests are classified as mezzanine equity and measured at the greater of estimated redemption value or carrying value at the end of each reporting period. Net loss attributed to noncontrolling interest is recorded in the Condensed Consolidated Statements of Income. Any adjustments to the redemption value of redeemable noncontrolling interest are recognized in either net income or through accumulated paid-in capital, depending on the nature of the underlying security (preferred or common units).
The components of redeemable noncontrolling interest are as follows:

Beginning balance December 31, 2020 | $ | 10 |  |  |
Net loss attributed to noncontrolling interest | (1) |  |  |
Ending balance September 30, 2021 | $ | 9 |  |  |

Senior Notes
In March 2021, LP issued $350 million of the 2029 Senior Notes. The Company may redeem the 2029 Senior Notes, in whole or in part, prior to March 15, 2024, at a redemption price equal to 100% of the principal amount thereof plus a “make-whole” premium set forth in the indenture governing the 2029 Senior Notes, plus accrued and unpaid interest, if any, to, but not including, the date of redemption. On or after March 15, 2024, LP may, at its option on one or more occasions, redeem all or any portion of these notes at the redemption prices set forth in the indenture governing the 2029 Senior Notes, plus accrued and unpaid interest, if any, to, but not including, the date of redemption. The indenture governing the 2029 Senior Notes contains certain covenants that, among other things, limit the Company's ability to grant liens to secure indebtedness, engage in sale and leaseback transactions and merge or consolidate or sell all or substantially all of its assets. If LP is subject to a "change of control," as defined in the indenture, LP is required to offer to repurchase the 2029 Senior Notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, thereon to, but not including, the date of purchase. The indenture governing the 2029 Senior Notes contains customary events of default, including failure to make required payments on the 2029 Senior Notes, failure to comply with certain agreements or covenants contained in the indenture, failure to pay or acceleration of certain other indebtedness and certain events of bankruptcy and insolvency. An event of default in the indenture allows either the indenture trustee or the holders of at least 25% in aggregate principal amount of the then-outstanding 2029 Senior Notes to accelerate, or in certain cases, automatically causes the acceleration of, the amounts due under the 2029 Senior Notes.
In September 2016, LP issued $350 million aggregate principal amount Senior Notes due 2024 (2024 Senior Notes). In February 2021, LP delivered to holders of the 2024 Senior Notes a conditional notice of redemption to redeem on March 27, 2021 all of the 2024 Senior Notes outstanding at a redemption price of 102.438% of the principal amount thereof plus accrued and unpaid interest to, but not including, the redemption date. The redemption notice became irrevocable on March 11, 2021, and the 2024 Senior Notes were fully redeemed on March 27, 2021. In connection with this redemption, LP recorded an early debt extinguishment charge of $11 million, recorded within Other non-operating items on the Condensed Consolidated Statements of Income, which included $9 million of redemption premium and $2 million of unamortized debt costs associated with these notes.
Deferred debt costs are amortized over the life of the related debt using a straight-line basis which approximates the effective interest method. If the debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired to Other non-operating items. During the nine months ended September 30, 2021, $2 million of deferred debt costs were written off in association with the 2024 Senior Notes extinguishment, and LP paid $4 million in debt issuance costs that will be deferred and amortized over the life of the 2029 Senior Notes.
Credit Facility
In August 2021, LP entered into a fourth amendment (Fourth Amendment) to its revolving credit facility, dated as of June 27, 2019 (Credit Facility), with American AgCredit, PCA, as administrative agent and CoBank, ACB, as letter of credit issuer, (as amended, the Amended Credit Facility). The Amended Credit Facility provides a revolving credit facility in the principal amount of up to $550 million, with a $60 million sub-limit for letters of credit. The revolving facility, pursuant to the Amended Credit Facility, terminates, and all loans made thereunder become due in June 2027. LP has granted a security interest in substantially all of its U.S. personal property to secure the Amended Credit Facility, and certain of LP’s existing and future wholly-owned domestic subsidiaries may guaranty its obligations under the Amended Credit Facility and, subject to certain limited exceptions, provide security through a security interest in substantially all the personal property of these subsidiaries. The Amended Credit Facility provides a release of security interest after obtaining an Investment Grade rating from any one of the Moody's, S&P, or Fitch. There are no outstanding amounts borrowed under the Amended Credit Facility as of September 30, 2021.
Revolving borrowings under the Amended Credit Facility accrue interest, at the Company's option, at either (a) a “base rate” plus a margin of 0.500% to 1.500% or (b) LIBOR plus a margin of 1.500% to 2.500%. The Amended Credit Facility also includes an unused commitment fee, due quarterly, ranging from 0.200% to 0.425%. The applicable margins and fees within these ranges are based on our ratio of consolidated EBITDA to cash interest
16

charges. The “base rate” is the highest of (i) the Federal funds rate plus 0.5%, (ii) the U.S. prime rate, and (iii) one-month LIBOR plus 1.0%.
The Amended Credit Facility contains various restrictive covenants and customary events of default, the occurrence of which could result in the acceleration of our obligation to repay the indebtedness outstanding thereunder. The Amended Credit Facility also contains financial covenants that require the Company and its consolidated subsidiaries to have, as of the end of each quarter, a capitalization ratio (i.e., funded debt less unrestricted cash to total capitalization) of no more than 57.5%.
In March 2020, LP entered into a letter of credit facility agreement (Letter of Credit Facility) with Bank of America, N.A., which provides for the funding of letters of credit up to an aggregate outstanding amount of $20 million, which may be secured by certain cash collateral of LP. The Letter of Credit Facility includes an unused commitment fee, due quarterly, ranging from 0.50% to 1.875% of the daily available amount to be drawn on each letter of credit issued under the Letter of Credit Facility. The Letter of Credit Facility is subject to similar affirmative, negative, and financial covenants as those set forth in the Amended Credit Facility, including the capitalization ratio covenant. As of September 30, 2021, LP secured $13 million of outstanding letters of credit with cash collateral, included in Restricted cash in its Condensed Consolidated Balance Sheets.
Deferred debt costs are amortized over the life of the related debt using a straight-line basis, which approximates the effective interest method. Included in such amortized amounts are deferred debt costs associated with LP's Amended Credit Facility, which are recorded within Other assets on its Condensed Consolidated Balance Sheets. During the nine months ended September 30, 2021, the Company paid $2 million in debt issuance costs in connection with the third amendment to the Credit Facility that LP entered into in June 2021 (Third Amendment). These debt issuance costs were deferred and will be amortized over the life of the Amended Credit Facility.
As of September 30, 2021, LP was in compliance with all covenants under the 2029 Senior Notes and the Amended Credit Facility (as well as the Letter of Credit Facility by such compliance).
NOTE 10. INCOME TAXES
For interim periods, we recognize income tax expense 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 in the current quarter. Changes in profitability estimates in various jurisdictions will impact our quarterly effective income tax rates.
The tax provision for income taxes for the nine months ended September 30, 2021 and 2020, reflected an estimated annual tax rate of 24% and 26%, respectively, excluding discrete items discussed below. The total effective tax rate for the three and nine months ended September 30, 2021, was 25% and 24%, respectively, compared to 25% and 27% for the comparable periods in 2020, respectively.
We recognized a net discrete tax benefit of $7 million during the nine months ended September 30, 2021, primarily related to stock-based compensation and adjustments to prior year, including an adjustment to the deferred tax rate. We recognized a net discrete tax expense of $3 million during the nine months ended September 30, 2020, primarily related to the surrender of a corporate-owned life insurance contract and a sale of ARS, offset by a benefit related to stock-based compensation.
NOTE 11. STOCK-BASED COMPENSATION
We have stock award plans for key employees and directors, pursuant to which awards of stock options, SSARs, restricted stock, restricted stock units, and performance stock units (PSUs) are granted. In addition, we offer an employee stock purchase plan to employees.
17

In July 2021, LP modified the performance vesting criteria of approximately 149,000 PSU awards granted in 2020. The modification was considered a Type III modification under the Accounting for Share-Based Payments (Topic 718), in which the original awards were canceled, and the modified awards were considered granted on the modification date. Post-modification stock-based compensation expense related to these awards will be recognized over the remaining service period using modification date fair values of between $56.35 and $64.12 and the number of awards expected to vest.
We recognized $5 million in stock-based compensation expense during the three months ended September 30, 2021, and 2020. We recognized $10 million and $8 million in stock-based compensation expense during the nine months ended September 30, 2021, and 2020, respectively. At September 30, 2021, there was $34 million of unrecognized stock-based compensation expense related to unvested PSUs, restricted stock units, and SSARs attributable to future service.
NOTE 12. COMMITMENTS AND CONTINGENCIES
We maintain reserves for various contingent liabilities as follows:

| September 30, 2021 |  | December 31, 2020
Environmental reserves | $ | 14 |  |  | $ | 14 |
Other reserves | — |  |  | — |
Total contingencies | 14 |  |  | 14 |
Current portion (included in Accrued liabilities) | (1) |  |  | (1) |
Long-term portion (included in Other long-term liabilities) | $ | 13 |  |  | $ | 13 |

Estimates of our loss contingencies are based on various assumptions and judgments. Due to the numerous uncertainties and variables associated with these assumptions and judgments, both the precision and reliability of the resulting estimates of the related contingencies are subject to substantial uncertainties. We regularly monitor our estimated exposure to contingencies and, as additional information becomes known, may change our estimates significantly. While no estimate of the range of any such change can be made at this time, the amount that we may ultimately pay in connection with these matters could materially exceed, in either the near term or the longer term, the amounts accrued to date. Our estimates of our loss contingencies do not reflect potential future recoveries from insurance carriers except to the extent that recovery may, from time to time, be deemed probable as a result of an insurer’s agreement to payment terms.
Environmental 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 considering 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 the 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.
18

Other Proceedings
From time to time, we and our subsidiaries are parties to certain 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. IMPAIRMENT OF LONG-LIVED ASSETS
We review the carrying values of our long-lived assets for potential impairments and believe we have adequate support for the carrying value of our long-lived assets. If demand and pricing for our products fall to levels significantly below cycle average demand and pricing, or should we decide to invest capital in alternative projects, or should changes occur related to our wood supply for our mills, it is possible that future impairment charges will be required. As of September 30, 2021, there were no indications of impairment.
We also review from time to time potential dispositions of various assets, considering 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.
During the three and nine months ended September 30, 2020, we recorded $1 million and $9 million, respectively, in pre-tax impairment charges primarily related to our fiber producing assets at a Siding facility.
NOTE 14. PRODUCT WARRANTIES
We offer 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 three and nine months ended September 30, 2021, and 2020, is summarized in the following table:

| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2021 |  | 2020 |  | 2021 |  | 2020
Beginning balance | $ | 8 |  |  | $ | 8 |  |  | $ | 8 |  |  | $ | 8 |
Accrued to expense | — |  |  | — |  |  | 1 |  |  | 1 |
Payments made | — |  |  | — |  |  | (1) |  |  | (1) |
Total warranty reserves | 8 |  |  | 8 |  |  | 8 |  |  | 8 |
Current portion of warranty reserves (included in Other current liabilities) | (2) |  |  | (2) |  |  | (2) |  |  | (2) |
Long-term portion of warranty reserves (included in Other long-term liabilities) | $ | 6 |  |  | $ | 6 |  |  | $ | 6 |  |  | $ | 6 |

We continue to monitor warranty and other claims associated with our products and believe as of September 30, 2021, that the warranty reserve balances associated with these matters are adequate to cover future warranty payments. However, it is possible that additional changes may be required in the future.

We received $1 million and $3 million in insurance recoveries during the three and nine months ended September 30, 2021, respectively, related to business interruption claims for weather-related downtime sustained in the prior year.
During the three and nine months ended September 30, 2020, we recognized a charge of $2 million related to additional estimated environmental costs to be paid by a third party associated with a non-operating site. We incurred severance and other charges of $1 million and $5 million for the three and nine months ended September 30, 2020, respectively, related to certain reorganizations and product-line discontinuance. We received $5 million and $9 million of Canadian wage subsidies during the three and nine months ended September 30, 2020, respectively. Additionally, we recorded a recovery of $1 million and charges of $9 million for the three and nine months ended September 30, 2020, respectively, related to the discontinuance of our fiber product (primarily related to fiber inventory adjustments to net realizable values).

NOTE 18. 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.
We evaluate the performance of our business segments based on net sales and Adjusted EBITDA. Accordingly, our chief operating decision maker evaluates performance and allocates resources based primarily on net sales and Adjusted EBITDA for our business segments. Adjusted EBITDA is a non-GAAP financial measure and is defined as income attributed to LP before interest expense, provision for income taxes, depreciation and amortization, and excludes stock-based compensation expense, loss on impairment attributed to LP, product-line discontinuance charges, other operating credits and charges, net, loss on early debt extinguishment, investment income, and other non-operating items.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
This Management's Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our Condensed Consolidated Financial Statements and related Notes and other financial information appearing elsewhere in this quarterly report on Form 10-Q. The following discussion includes statements that are forward-looking statements that are based on the beliefs of our management, as well as assumptions made by, and information currently available to our management.
General
We are a leading provider of high-performance building solutions that meet the demands of builders, remodelers, and homeowners worldwide. We have leveraged our expertise serving the new home construction, repair and remodeling, and outdoor structures markets to become an industry leader known for innovation, quality, and reliability. Our manufacturing facilities are located in the U.S., Canada, Chile, and Brazil.
To serve these markets, we operate in four segments: Siding, OSB, EWP, and South America.
In February 2021, we announced our decision to explore strategic alternatives with respect to the Company's remaining EWP segment, including a possible sale in whole or in part. In September 2021, we ceased the production of LSL production in connection with the conversion of the Houlton, Maine facility from LSL and OSB production to Siding production, as previously announced.
The COVID-19 pandemic did not materially impact our results of operations for the three and nine months ended September 30, 2021. In September 2021, the federal government announced a six-point plan for responding to the COVID-19 pandemic. Part of his plan provides that the Occupational Health and Safety Administration (“OSHA”) will develop a rule which will require all employers with 100 or more employees to require their workforce to be fully vaccinated (or, alternatively, to provide a negative COVID test result on a weekly basis). The employer mandate has not yet gone into effect and further details, including any proposed OSHA rules, have not been released. We are monitoring developments related to these plans as information becomes available to assess how these plans, including any national or state vaccine mandates, may impact our workforce. However, the duration of the COVID-19 pandemic, the emergence and severity variants of the virus, the possibility of additional subsequent widespread outbreaks, the success of actions to contain the pandemic and mitigate its impacts, the impact of federal or state vaccine mandates, and the effects on our operations cannot be reasonably estimated.
Demand for our Building Products
Demand for our products correlates positively with new home construction and repair and remodeling activity in North America, which historically have been characterized by significant cyclicality. The U.S. Department of Census reported on October 19, 2021, that actual single housing starts were 4% and 20% higher for the three and nine months ended September 30, 2021, respectively, as compared to the same periods in 2020. Repair and remodeling activity is difficult to reasonably measure, but many indications, including the increase in LP’s retail sales, suggest that repair and remodeling activity grew in the first nine months of 2021 as compared to the corresponding period in the prior year.
Although housing market demand has recently been very strong, future economic conditions in the United States and the demand for homes remain uncertain due to continuing COVID-19-related disruptions, government directives, actions and economic relief efforts related thereto, and the impact of these actions on the economy, employment levels, consumer confidence, and financial markets, among other things. Additionally, as a result of increased demand in the housing market and a strengthening economy in the United States, we have experienced increases in material prices, supply disruptions, and labor shortages, which will be a challenge for LP as we continue to work to meet the demands of builders, remodelers, and homeowners worldwide. The potential effect of these factors on our future operational and financial performance is uncertain. As a result, our past performance may not be indicative of future results.
24

Supply and Demand for OSB
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 have experienced increased demand for commodity OSB in the nine months ended September 30, 20212021; however, we cannot predict whether the prices of our OSB products will remain at current levels or increase or decrease in the future.
For additional factors affecting our results, refer to the "Overview" within our Management's Discussion and Analysis of Financial Condition and Results of Operations and “Risk Factors” contained in our 2020 Annual Report on Form 10-K, and to “About Forward-Looking Statements” in this quarterly report on Form 10-Q.
Critical Accounting Policies and Significant Estimates
Note 1 of the Notes to the Consolidated Financial Statements included in our 2020 Annual Report on Form 10-K 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.
While there have been no changes in the application of principles, methods, and assumptions used to determine our significant estimates, we may be required to revise certain accounting estimates and judgments related to the economic and business impact of the COVID-19 pandemic, such as, but not limited to, those related to the valuation of goodwill, intangibles, long-lived assets, accounts receivable, and inventory, which could have a material adverse effect on our financial position and results of operations.
Non-GAAP Financial Measures and Other Key Performance Indicators
In evaluating our business, we utilize non-GAAP financial measures that fall within the meaning of SEC Regulation G and Regulation S-K Item 10(e), which we believe provide users of the financial information with additional meaningful comparison to prior reported results. Non-GAAP financial measures do not have standardized definitions and are not defined by U.S. GAAP. In this quarterly report on Form 10-Q, we disclose income attributed to LP before interest expense, provision for income taxes, depreciation and amortization, and excludes stock-based compensation expense, loss on impairment attributed to LP, product-line discontinuance charges, other operating credits and charges, net, loss on early debt extinguishment, investment income, and other non-operating items as Adjusted EBITDA (Adjusted EBITDA) which is a non-GAAP financial measure. We have included Adjusted EBITDA in this report because we view it as an important supplemental measure of our performance and believe that it is frequently used by interested persons in the evaluation of companies that have different financing and capital structures and/or tax rates. We also disclose income attributed to LP, excluding loss on impairment attributed to LP, product-line discontinuance charges, interest expense outside of normal operations, other operating credits and charges, net, loss on early debt extinguishment, gain (loss) on acquisition, and adjusted for a normalized tax rate as Adjusted Income (Adjusted Income). We also disclose Adjusted Diluted EPS, calculated as Adjusted Income divided by diluted shares outstanding. We believe that Adjusted Diluted EPS and Adjusted Income are useful measures for evaluating our ability to generate earnings and that providing this measure should allow interested persons to more readily compare the earnings for past and future periods.
Neither Adjusted EBITDA, Adjusted Income, nor Adjusted Diluted EPS is a substitute for the U.S. GAAP measure of net income or for any other U.S. GAAP measures of operating performance. It should be noted that other companies may present similarly-titled measures differently and therefore, as presented by us, these measures may not be comparable to similarly-titled measures reported by other companies. Adjusted EBITDA, Adjusted Income, and Adjusted Diluted EPS have material limitations as performance measures because they exclude items that are actually incurred or experienced in connection with the operations of our business.
The following table presents significant items by operating segment and reconciles Net income to Adjusted EBITDA (dollar amounts in millions):

Siding net sales increased by $44 million and $189 million for the three and nine months ended September 30, 2021, respectively, compared to the corresponding periods in 2020. These increases are primarily due to increases in Siding Solutions prices and shipments for the three and nine months ended September 30, 2021, respectively, partially offset by decreases in fiber sales (included in the Other product line).
Adjusted EBITDA decreased by $3 million for the three months ended September 30, 2021, compared to the corresponding period in 2020, primarily due to increases in raw material prices, freight costs, sales and marketing, and maintenance costs, offset by higher Siding Solutions revenue. Adjusted EBITDA increased by $71 million for the nine months ended September 30, 2021, compared to the corresponding period in 2020, primarily due to an increase in Siding Solutions revenue, partially offset by increases in raw material prices, freight costs, sales and marketing, and mill spending.

Adjusted EBITDA increased over the prior year by $192 million and $1 billion for the three and nine months ended September 30, 2021, respectively, primarily due to increased OSB prices, partially offset by increases in raw material prices, freight costs, and mill spending.
EWP
The EWP segment is comprised of LP® SolidStart® I-Joist (I-Joist), Laminated Veneer Lumber (LVL), and Laminated Strand Lumber (LSL) and other related products. This segment also includes the sales of I-Joist and LVL products produced by our joint venture and sales of plywood produced as a by-product of the LVL production process. In February 2021, we announced that we are exploring strategic alternatives to the remaining EWP business, including a possible sale in whole or in part.
Segment sales, Adjusted EBITDA, and Adjusted EBITDA margin for this segment were as follows:

EWP net sales increased by $98 million and $200 million for the three and nine months ended September 30, 2021, respectively, compared to the corresponding periods in 2020. Adjusted EBITDA increased by $33 million and $47 million for the three and nine months ended September 30, 2021, respectively, compared to the corresponding periods in 2020. The increases to net sales and Adjusted EBITDA are primarily due to increased pricing to offset increased input costs.
SOUTH AMERICA
Our South America segment manufactures and distributes OSB structural panel and siding products in South America and certain export markets. This segment has manufacturing operations in two countries, Chile and Brazil, and operates sales offices in Chile, Brazil, Peru, Colombia, and Argentina.

South America net sales increased by $31 million and $84 million for the three and nine months ended September 30, 2021, respectively, compared to the corresponding periods in 2020, primarily due to higher OSB and siding pricing.
Adjusted EBITDA increased by $26 million and $62 million for the three and nine months ended September 30, 2021, respectively, compared to the corresponding periods in 2020, primarily due to the increased pricing, partially offset by higher imported raw material costs.
OTHER PRODUCTS
Our Other products segment includes off-site framing operation Entekra Holdings, LLC, ("Entekra") remaining timber and timberlands, and other minor products, services, and closed operations, which do not qualify as discontinued operations. Other net sales were $30 million and $73 million for the three and nine months ended September 30, 2021, respectively, as compared to $11 million and $36 million for the corresponding periods in 2020. These increases are primarily due to increases in Entekra sales volumes.
Adjusted EBITDA was $(3) million and $(11) million for the three and nine months ended September 30, 2021, respectively, as compared to $(5) million and $(13) million for the corresponding periods in 2020, respectively.
SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
Selling, general and administrative expenses were $63 million and $168 million for the three and nine months ended September 30, 2021, respectively, compared to $52 million and $157 million for the corresponding periods in 2020. The increase in 2021 is primarily due to increased travel, sales and marketing, and corporate overhead primarily driven by restrictions on such activities in 2020 in response to the onset of the COVID-19 pandemic.
INCOME TAXES
We recognized an estimated tax provision of $123 million and $366 million for the three and nine months ended September 30, 2021, respectively, compared to $60 million and $88 million for the corresponding periods of 2020. 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. For 2021, the primary differences between the U.S. statutory rate of 21% and the effective rate relate to state income tax. For 2020, the primary differences between the U.S.
31

statutory rate of 21% and the effective rate related to state income tax, foreign tax rates, the sale of our ARS and the redemption of our company-owned life insurance cash surrender value.
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 2020 Annual Report on Form 10-K and Note 12 of the Notes to the Condensed Consolidated Financial Statements included in Item 1 of this quarterly report on Form 10-Q.
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 such credit facilities as we may have in effect from time to time. We may also, from time to time, issue and sell equity, debt or hybrid securities, or engage in other capital market transactions.
Our principal uses of liquidity are paying the costs and expenses associated with our operations, servicing outstanding indebtedness, paying dividends, and making capital expenditures. We may also, from time to time, prepay or repurchase outstanding indebtedness or shares 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 affecting any such repurchases may be changed at any time, or from time to time, without prior notice.
OPERATING ACTIVITIES
During the three months ended September 30, 2021, and 2020, cash provided by operations was $511 million and $218 million, respectively. During the nine months ended September 30, 2021, and 2020, cash provided by operations was $1.3 billion and $338 million, respectively. The improvement in cash provided by operations for the period ended September 30, 2021, was primarily related to increases in OSB commodity pricing and revenue growth in Siding Solutions.
INVESTING ACTIVITIES
During the three months ended September 30, 2021, and 2020, cash used in investing activities was $68 million and $13 million, respectively. During the nine months ended September 30, 2021, and 2020, cash used in investing activities was $131 million and $25 million, respectively.
Capital expenditures for the three months ended September 30, 2021, and 2020, were $68 million and $14 million, respectively. Capital expenditures for the nine months ended September 30, 2021, and 2020, were $133 million and $53 million, respectively, primarily related to siding conversion expenditures and growth and maintenance capital. We expect to fund our capital expenditures through cash on hand and cash generated from operations.
During the three and nine months ended September 30, 2020, we received $1 million and $15 million, respectively, in cash related to the divestiture of our East River facility and assets and brand rights of CanExel®. During the nine months ended September 30, 2020, we received $10 million related to the cash surrender value of the company-owned life insurance policy, and $3 million related to the sale of our ARS.
FINANCING ACTIVITIES
During the three and nine months ended September 30, 2021, cash used in financing activities was $416 million and $1.1 billion, respectively. During the nine months ended September 30, 2021, we used $300 million to repurchase
32

shares of LP common stock under the 2020 Share Repurchase Program. The 2020 Share Repurchase Program was exhausted in May 2021. During the three and nine months ended September 30, 2021, we used $399 million and $687 million, respectively, to repurchase shares of LP common stock under the 2021 Share Repurchase Program. We paid cash dividends of $17 million and $50 million in the three and nine months ended September 30, 2021, respectively.
Additionally, in March 2021, we issued $350 million aggregate principal amount of the 2029 Senior Notes. In February 2021, LP delivered to holders of the 2024 Senior Notes a conditional notice of redemption to redeem on March 27, 2021 all of the 2024 Senior Notes outstanding at a redemption price of 102.438% of the principal amount thereof plus accrued and unpaid interest to, but not including, the redemption date. The redemption notice became irrevocable on March 11, 2021, and the 2024 Senior Notes were fully redeemed on March 27, 2021. In connection with financing activities, we paid $2 million in debt issuance costs related to the Third Amendment and $13 million in redemption premiums and debt issuance costs related to the 2024 Senior Notes during the nine months ended September 30, 2021. The remaining financing activities relate to the repurchase of stock from employees in connection with income tax withholding requirements associated with our employee stock-based compensation plans.
During the three and nine months ended September 30, 2020, cash used in financing activities was $45 million and $84 million, respectively. During the three months ended September 30, 2020, we used $29 million to repurchase shares of LP common stock under the 2020 Share Repurchase Program. During the three and nine months ended September 30, 2020, we paid cash dividends of $16 million and $49 million, respectively. In March 2020, we borrowed $350 million under our Amended Credit Facility as a precautionary measure due to the COVID-19 pandemic, and we repaid the outstanding balance in the second quarter of 2020. We also paid $1 million of financing costs associated with our Amended Credit Facility during the nine months ended September 30, 2020. Additionally, during the nine months ended September 30, 2020, we used $5 million to repurchase stock from employees in connection with income tax withholding requirements associated with our employee stock-based compensation plans.
CREDIT FACILITY AND LETTER OF CREDIT FACILITY
The Amended Credit Facility provides for a revolving credit facility in the principal amount of up to $550 million, with a $60 million sub-limit for letters of credit. The Amended Credit Facility, and all loans thereunder, become due on June 8, 2027. As of September 30, 2021, we had no amounts outstanding under the Amended Credit Facility.
The Amended Credit Facility contains various restrictive covenants and customary events of default, the occurrence of which could result in the acceleration of our obligation to repay the indebtedness outstanding thereunder. The Amended Credit Facility also contains financial covenants that require us and our consolidated subsidiaries to have, as of the end of each quarter, a capitalization ratio (i.e., funded debt less unrestricted cash to total capitalization) of no more than 57.5%. As of September 30, 2021, we were in compliance with all financial covenants under the Amended Credit Facility.
In March 2020, LP entered into the Letter of Credit Facility, which provides for the funding of letters of credit up to an aggregate outstanding amount of $20 million, which may be secured by certain cash collateral of LP. The Letter of Credit Facility includes an unused commitment fee, due quarterly, ranging from 0.50% to 1.875% of the daily available amount to be drawn on each letter of credit issued under the Letter of Credit Facility. The Letter of Credit Facility is subject to similar affirmative, negative, and financial covenants as those set forth in the Amended Credit Facility, including the capitalization ratio covenant. As of September 30, 2021, we were in compliance with all covenants under the Letter of Credit Facility.
OTHER LIQUIDITY MATTERS
Off-Balance Sheet Arrangements
33

As of September 30, 2021, we had standby letters of credit of $12 million outstanding related to collateral for environmental impact on owned properties, deposit for forestry license, and insurance collateral, including workers' compensation.
Potential Impairments
We review our mill and investment assets for potential impairments at least annually and believe we have adequate support for the carrying value of our assets as of September 30, 2021.
If demand and pricing for our products are significantly below cycle average demand and pricing, or should we decide to invest capital in alternative projects, or should changes occur related to our wood supply for these locations, or should demand and pricing of our products fall as a result of the long-term effects of the COVID-19 pandemic, it is possible that future impairment charges will be required. As of September 30, 2021, there were no indications of impairment. We recognized a non-cash impairment charge of $5 million during the nine months ended September 30, 2020 related to goodwill assigned to the Entekra reporting unit in part due to the impacts at that time the COVID-19 pandemic on this reporting unit.
We also review from time to time possible dispositions of various assets, considering 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.
34

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 North America annual production capacity in the OSB segment of 4.5 billion square feet (3/8" basis) or 3.9 billion square feet (7/16" basis), a $1 change in the annual average price per thousand square feet on a 7/16" basis would change annual pre-tax profits by approximately $4 million.
We are exposed to market risk associated with changes in interest rates on our variable rate long-term debt. As of September 30, 2021, we had no outstanding amounts borrowed under our Amended Credit Facility. We do not currently have any derivative or hedging arrangements, or other known exposures, to changes in interest rates.
We historically have not entered into material commodity futures and swaps, although we may do so in the future.
35

ITEM 4.CONTROLS AND PROCEDURES.
Evaluation of Disclosure Controls and Procedures
As of September 30, 2021, our Chief Executive Officer and Chief Financial Officer carried out, with the participation of the Company's management, a review and evaluation of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) promulgated under the Exchange Act. Based upon this evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of September 30, 2021, LP’s disclosure controls and procedures were effective.
Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting that occurred during our most recently completed fiscal quarter, ended September 30, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

LOUISIANA-PACIFIC CORPORATION AND SUBSIDIARIES
KEY PERFORMANCE INDICATORS
The following tables set forth: (1) housing starts, (2) our North American sales volume, and (3) OEE. We consider the following items to be key performance indicators because LP’s management uses these metrics to evaluate our business and trends, measure our performance, and make strategic decisions and believes that the key performance indicators presented provide additional perspective and insights when analyzing the core operating performance of LP. These key performance indicators should not be considered superior to, as a substitute for or as an alternative to, and should be considered in conjunction with, the U.S. GAAP financial measures presented herein. These measures may not be comparable to similarly-titled performance indicators used by other companies.
We monitor housing starts, which is a leading external indicator of residential construction in the United States that correlates with the demand for many of our products. We believe that this is a useful measure for evaluating our results and that providing this measure should allow interested persons to more readily compare our sales volume for past and future periods to an external indicator of product demand. Other companies may present housing start data differently and therefore, as presented by us, our housing start data may not be comparable to similarly-titled indicators reported by other companies.

1 Actual U.S. Housing starts data reported by U.S. Census Bureau as published through October 19, 2021.

We monitor sales volumes for our products in our Siding, OSB and EWP segments, which we define as the number of units of our products sold within the applicable period. Evaluating sales volume by product type helps us identify and address changes in product demand, broad market factors that may affect our performance, and opportunities for future growth. It should be noted that other companies may present sales volumes differently and, therefore, as presented by us, sales volumes may not be comparable to similarly-titled measures reported by other companies. We believe that sales volumes can be a useful measure for evaluating and understanding our business.
The following table sets forth North American sales volumes for the three and nine months ended September 30, 2021, and 2020:

| Three Months Ended September 30, 2021 |  | Three Months Ended September 30, 2020

We measure OEE of each of our mills to track improvements in the utilization and productivity of our manufacturing assets. OEE is a composite metric that considers asset uptime (adjusted for capital project downtime and similar events), production rates, and finished product quality. It should be noted that other companies may present OEE differently and, therefore, as presented by us, OEE may not be comparable to similarly-titled measures reported by other companies. We believe that when used in conjunction with other metrics, OEE can be a useful measure for evaluating our ability to generate profits, and that providing this measure should allow interested persons to more readily monitor operational improvements. OEE for the three and nine months ended September 30, 2021, and 2020 for each of our segments is listed below:

| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2021 |  | 2020 |  | 2021 |  | 2020
Siding | 91 | % |  | 88 | % |  | 89 | % |  | 88 | %

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.
In February 2020, LP’s Board of Directors authorized the 2020 Share Repurchase Program under which LP was authorized to repurchase up to $200 million of shares of LP’s common stock. In November 2020, LP’s Board of Directors authorized the expansion of the 2020 Share Repurchase Program under which LP was authorized to repurchase up to an additional $300 million of shares of LP’s common stock. The 2020 Share Repurchase Program was exhausted in May 2021. On May 4, 2021, our Board of Directors authorized the 2021 Share Repurchase Program under which LP may repurchase up to $1 billion of shares of LP's common stock. LP may initiate, discontinue or resume purchases of its common stock under the 2021 Share Repurchase Program and make additional repurchases of common stock in the open market, in block and privately-negotiated transactions, including under Rule 10b5-1 plans, at times and in such amounts as management deems appropriate without prior notice, subject to market and business conditions, regulatory requirements and other factors.
The following shares of our common stock were repurchased under these authorizations during the quarter ended September 30, 2021:
