Leases (Notes)

Leases (Notes)	3 Months Ended

Leases [Abstract]
Leases of Lessee Disclosure [Text Block]	NOTE 2 - LEASES On January 1, 2019, we adopted ASU 2016-02, "Leases (Topic 842)" (ASC 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 company 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 2018-11, "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 adjustment to retained earnings. The amendments have the same effective date and transition requirements as the new lease standard. We have elected to adopt using this optional transition method. We determine if an arrangement is a lease at contract inception. A lease exists when a contract conveys to the customer the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. Our lease portfolio consists primarily of real estate, mobile equipment at our manufacturing facilities, railcars to transport our products, and a fleet of vehicles. As part of our adoption of ASC 842, we have also elected to apply the following practical expedients as permitted under the new standard: • Package of practical expedients - we will not reassess whether expiring or existing contracts contain a lease, will not reassess the classification of expired or existing leases, and will not reassess whether lease initial direct costs would qualify for capitalization under the new lease accounting standard. • Lease and non-lease components as lessee - for leases across all asset classes in which we are a lessee, we will not separate non-lease components from lease components and instead will account for each separate lease component and the non-lease components associated with that lease component as a single lease component. • Short-term leases - we have elected not to recognize ROU assets and lease liabilities for short-term leases across all asset classes that have a lease term of 12 months or less. We recognize the lease payments associated with our short-term leases as an expense on a straight-line basis over the lease term. Key estimates and judgments include how we determined the discount rate used to record the unpaid lease payments at present value and lease term. • ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. As most of our leases do not provide an implicit rate, we used our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. • The lease term for all of our leases includes the noncancellable period of the lease plus any additional periods covered by either an option to extend (or not to terminate) the lease that we are reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor.

In connection with the ASR program, we entered into an agreement with Goldman, Sachs & Co. (GS) to repurchase $ 400 million of our common stock. Under the ASR, we received approximately 12 million shares of our common stock during the quarter ended March 31, 2019. At the final settlement of the ASR program, which is expected to occur prior to the end of the third quarter of 2019, GS may be required to deliver additional shares of common stock to us or, under certain circumstances, we may be required to deliver shares of our common stock or may elect to make a cash payment to GS, with the number of shares to be delivered or the amount of such payment based on the difference between the volume-weighted average price, less a discount, of our common stock during the term of the agreement and the initial $ 400 million paid.

Redeemable Noncontrolling Interest	NOTE 10 - REDEEMABLE NONCONTROLLING INTEREST Redeemable noncontrolling interest are interests in subsidiaries that are 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 at the end of each reporting period or the historical cost basis of the noncontrolling interest adjusted for cumulative earnings allocations. The resulting increases or decreases in the estimated redemption amount of redeemable preferred noncontrolling interest are affected by corresponding charges through income. Any adjustments recognized on redeemable common noncontrolling interest are affected by corresponding charges to accumulated paid in capital. During the first quarter of 2019, we obtained a controlling interest in Entekra Holdings, LLC (Entekra). Entekra's results of operations have been fully consolidated for periods after December 31, 2018 and we established a redeemable noncontrolling interest related to the minority holders. Due to the pre-existing ownership interest in Entekra, this acquisition was accounted for as a step acquisition in accordance with ASC 805, "Business Combinations". We recognized a gain of $14 million recorded within other non-operating items on our Consolidated Statements of Income in connection with this transaction to record our ownership interest in Entekra at fair value on the acquisition date based upon an appraisal. Including our previously owned interest, we acquired net assets of $ 56 million , consisting of $41 million in current assets, $ 6 million in fixed assets, $ 25 million of goodwill and other intangible assets less $ 1 million in current liabilities and $15 million in non-controlling interest. Certain information about Entekra (e.g., pro forma financial information and allocation of purchase price) is not presented because such information is not material to our results of operations and financial position. Quarter Ended March 31, 2019 2018 Beginning balance $ — $ — Purchase of redeemable common and preferred stock 15 — Adjustment to redemption value — — Net loss attributable to redeemable non-controlling interest — — Ending balance $ 14 $ — As of March 31, 2019, Entekra has entered into a long term lease associated with their manufacturing facility which is currently under construction. In accordance with ASC 842, Entekra does not yet control the underlying asset. When Entekra obtains control, we anticipate that we will increase our ROU assets by $ 18 million and the related lease liability by a comparable amount.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES 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 profitability estimates in various jurisdictions will impact our quarterly effective income tax rates. For the first three months of 2019, our income tax expense on continuing operations reflects a rate of 21% as compared to 24% in the comparable period of 2018. For the first three months of 2019, our effective rate of 21% is equal to the U.S. statutory rate of 21% , as increases caused by the effects of foreign and state tax rates are offset by several discrete first quarter benefit items, including tax deductions related to stock-based compensation and the favorable resolution of prior period Chilean tax positions. For the first three months of 2018, the primary differences between the U.S. statutory rate of 21% and the effective rate of 24% relates to state income taxes, foreign tax rates and tax deductions related to stock-based compensation.

Legal and Environmental Matters [Abstract]
Legal and Environmental Matters	LEGAL AND ENVIRONMENTAL MATTERS Certain environmental matters and legal proceedings are discussed below. 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. Recorded in Other assets is $1 million related to a receivable for reimbursements of environmental costs associated with a non-operating site as of March 31, 2019 . 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.

Selected Segment Data	SELECTED SEGMENT DATA We operate in four segments: Siding, North America Oriented Strand Board (OSB), Engineered Wood Products (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, 2018 . During the first quarter of 2019, certain timber operations where reclassified from other to EWP and we have reclassifed a significant portion of our unallocated expenses to the business segments effective during the first quarter of 2019.

Asset Impairment Charges [Abstract]
Potential Impairments	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.

Lessee, Lease, Description [Line Items]
Leases of Lessee Disclosure [Text Block]	NOTE 2 - LEASES On January 1, 2019, we adopted ASU 2016-02, "Leases (Topic 842)" (ASC 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 company 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 2018-11, "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 adjustment to retained earnings. The amendments have the same effective date and transition requirements as the new lease standard. We have elected to adopt using this optional transition method. We determine if an arrangement is a lease at contract inception. A lease exists when a contract conveys to the customer the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. Our lease portfolio consists primarily of real estate, mobile equipment at our manufacturing facilities, railcars to transport our products, and a fleet of vehicles. As part of our adoption of ASC 842, we have also elected to apply the following practical expedients as permitted under the new standard: • Package of practical expedients - we will not reassess whether expiring or existing contracts contain a lease, will not reassess the classification of expired or existing leases, and will not reassess whether lease initial direct costs would qualify for capitalization under the new lease accounting standard. • Lease and non-lease components as lessee - for leases across all asset classes in which we are a lessee, we will not separate non-lease components from lease components and instead will account for each separate lease component and the non-lease components associated with that lease component as a single lease component. • Short-term leases - we have elected not to recognize ROU assets and lease liabilities for short-term leases across all asset classes that have a lease term of 12 months or less. We recognize the lease payments associated with our short-term leases as an expense on a straight-line basis over the lease term. Key estimates and judgments include how we determined the discount rate used to record the unpaid lease payments at present value and lease term. • ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. As most of our leases do not provide an implicit rate, we used our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. • The lease term for all of our leases includes the noncancellable period of the lease plus any additional periods covered by either an option to extend (or not to terminate) the lease that we are reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor.
