Discontinued Operations And Disposal Groups [Abstract]
Sale of Deltic MDF Facility	NOTE 3. SALE OF DELTIC MDF FACILITY On December 20, 2018, we entered into an Asset Purchase and Sale Agreement (the Agreement) with Roseburg Forest Products Co. to sell the Deltic MDF facility for $92.0 million, consisting of $63.0 million in cash and assumption of $29.0 million of revenue bonds. The purchase price was subject to post-closing adjustments for certain changes in working capital as defined in the Agreement. The transaction closed on February 12, 2019 resulting in a $9.2 million pre-tax gain on sale. Net proceeds received in February 2019 after closing costs and other expenses were $60.0 million. The net proceeds were reduced by $1.2 million during the second quarter of 2019 following the finalization of the post-closing working capital adjustments. A portion of the purchase price was escrowed pending satisfaction of certain covenants as outlined in the Agreement. These funds were fully released to us during the three months ended March 31, 2020. In addition, we had a carryover tax basis in the facility from the Deltic merger, and as a result, we recorded a reduction to deferred tax liabilities and increase to income taxes payable of $15.8 million at the date of sale. The sale of the MDF facility was not considered a strategic shift that has or will have a major effect on our operations or financial results and therefore did not meet the requirements for presentation as discontinued operations.

Contract Balances In general, a customer receivable is recorded as we deliver wood products, logs and residuals. We generally receive payment shortly after products have been received by our customers. At March 31, 2020 and December 31, 2019, we recorded $4.8 million and $5.5 million, respectively, for contract liabilities recorded as deferred revenue. These contract liabilities predominately relate to hunting and other access rights on our timberlands and member related activities at the Chenal Country Club. These contract liabilities are recognized over the term of the contracts, which is typically twelve months or less, except membership initiation fees at the country club which typically are recognized up to 10 years. Other contract asset and liability balances, such as prepayments, are immaterial. For real estate sales, we typically receive the entire consideration in cash at closing.

Segment Information

Segment Reporting [Abstract]
Segment Information	NOTE 5. SEGMENT INFORMATION Our businesses are organized into three reportable operating segments: Timberlands, Wood Products and Real Estate. The Timberlands segment includes planting and harvesting trees and building and maintaining roads. The Timberlands segment also generates revenues from non-timber resources such as hunting leases, recreation permits and leases, mineral rights contracts, oil and gas royalties and carbon sequestration. The Wood Products segment manufactures and markets lumber and plywood. The Real Estate segment includes the sale of land holdings deemed non-strategic or identified as having higher and better use alternatives, master planned community development and a country club. The reportable segments follow the same accounting policies used for our Condensed Consolidated Financial Statements Management primarily evaluates the performance of its segments and allocates resources to them based upon Adjusted EBITDDA. EBITDDA is calculated as net (loss) income before interest expense, income taxes, basis of real estate sold, depreciation, depletion and amortization. Adjusted EBITDDA further excludes certain specific items that are considered to hinder comparison of the performance of our businesses either year-on-year or with other businesses. Management uses Adjusted EBITDDA to compare the operating performance of our segments on a consistent basis and to evaluate the performance and effectiveness of each segment’s operational strategies. Our calculation of Adjusted EBITDDA may not be comparable to that reported by other companies. The following table summarizes information for each of the company’s reportable segments and includes a reconciliation of Total Adjusted EBITDDA to (loss) income before income taxes. Corporate information is included to reconcile segment data to the Condensed Consolidated Financial Statements .

Earnings per Share	NOTE 6. EARNINGS PER SHARE The following table reconciles the number of shares used in calculating basic and diluted earnings per share: Three Months Ended March 31, (in thousands, except per share amounts) 2020 2019 Net (loss) income $ (16,832 ) $ 6,560 Basic weighted-average shares outstanding 67,478 67,860 Incremental shares due to: Performance shares — 36 Restricted stock units — 20 Diluted weighted-average shares outstanding 67,478 67,916 Basic net (loss) income per share $ (0.25 ) $ 0.10 Diluted net (loss) income per share $ (0.25 ) $ 0.10 For stock-based awards, the dilutive effect is calculated using the treasury stock method. Under this method, the dilutive effect is computed as if the awards were exercised at the beginning of the period (or at time of issuance, if later) and assumes the related proceeds were used to repurchase common stock at the average market price during the period. Related proceeds include future compensation cost associated with the stock award. For the three months ended March 31, 2020 and 2019, there were approximately 317,000 and 90,000 stock-based awards that were excluded from the calculation of diluted earnings per share because they were anti-dilutive. Anti-dilutive stock-based awards could be dilutive in future periods. Share Repurchase Program On August 30, 2018, our board of directors authorized management to repurchase up to $100.0 million of common stock with no time limit set for the repurchase (the 2018 Repurchase Program). During the three months ended March 31, 2020 and 2019, we repurchased 400,917 and 278,947 shares of common stock (at a total consideration of $12.4 million and $10.2 million), respectively, under the 2018 Repurchase Program. All common stock purchases under the 2018 Repurchase Program were made in open-market transactions. At March 31, 2020, we had remaining authorization of $62.5 million for future stock repurchases under the 2018 Repurchase Program. We record share repurchases upon trade date as opposed to the settlement date when cash is disbursed. We record a liability to account for repurchases that have not been cash settled. There were no unsettled repurchases as of March 31, 2020. We retire shares upon repurchase. Any excess repurchase price over par is recorded in accumulated deficit.

Debt Disclosure [Abstract]
Debt	NOTE 8. DEBT At March 31, 2020, our total outstanding long-term debt included $693.5 million of term loans under our Second Amended and Restated Term Loan Agreement (Amended Term Loan Agreement) with our primary lender, of which $46.0 million matures in December 2020. Certain borrowings under the Amended Term Loan Agreement are at variable rates of one or three-month LIBOR plus a spread between 1.85% and 2.15%. We have entered into interest rate swaps for these variable rate term loans to fix the interest rate. See Note: 9 Derivative Instruments At March 31, 2020 there were no borrowings under our $380.0 million revolving line of credit and approximately $1.0 million of our revolving line of credit was utilized for outstanding letters of credit. As provided in the revolving line of credit agreement, borrowings may be increased by up to an additional $420.0 million. The revolving line of credit agreement also includes a sublimit of $75.0 million for the issuance of standby letters of credit and a sublimit of $25.0 million for swing line loans. Usage under either or both subfacilities reduces availability under the revolving line of credit. We may utilize borrowings under the credit facility to, among other things, refinance existing indebtedness and provide funding for working capital requirements, capital projects, acquisitions and other general corporate expenditures. We were in compliance with all debt and credit agreement covenants at March 31, 2020.

Derivative Instrument Detail [Abstract]
Derivative Instruments	NOTE 9. DERIVATIVE INSTRUMENTS From time to time, we enter into derivative financial instruments to manage certain cash flow and fair value risks. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset or liability to a particular risk are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in the cash flows of a specific asset or liability that is attributable to a particular risk, such as interest rate risk, are considered cash flow hedges. At March 31, 2020, we have six interest rate swaps associated with $397.5 million of term loan debt. The cash flow hedges convert variable rates ranging from three-month and one-month LIBOR plus 1.85% to 2.15%, to fixed rates ranging from 3.17% to 4.82%. Our cash flow hedges are expected to be highly effective in achieving offsetting cash flows attributable to the hedged interest rate risk through the term of the hedges. In March 2020, we entered into $653.5 million of forward starting interest rate swaps. These forward starting interest rate swaps effectively hedge the variability in future benchmark interest payments attributable to changes in interest rates on future debt refinancing. We entered into these forward starting interest rate swaps in order to lock in fixed rates on our anticipated future refinancing of $653.5 million of term loan debt maturing December 2020 through January 2029. The fixed interest rates for these forward swaps range from 0.85% to 1.17%. The variable rate component on these forward interest rate swaps is one-month LIBOR. Accordingly, the forward rate swaps were designated as cash flow hedges. In addition, these cash flow hedges require settlement on the stated maturity date for each respective term loan currently outstanding. The following table presents the gross fair values of derivative instruments on our Condensed Consolidated Balance Sheets Asset Derivatives Liability Derivatives (in thousands) Location March 31, 2020 December 31, 2019 Location March 31, 2020 December 31, 2019 Derivatives designated in cash flow hedging relationships: Interest rate contracts Other assets, current 1 $ — $ — Accounts payable and accrued liabilities 1 $ 1,368 $ — Interest rate contracts Other assets, non-current — 1,601 Other long-term obligations 59,764 22,398 $ — $ 1,601 $ 61,132 $ 22,398 1 The following table details the effect of derivatives on our Condensed Consolidated Statements of Operations Three Months Ended March 31, (in thousands) Location 2020 2019 Derivatives designated in fair value hedging relationships: Interest rate contracts Realized loss on interest rate contracts 1 Interest expense $ — $ (18 ) Loss on hedged debt basis adjustment included in debt extinguishment — (165 ) $ — $ (183 ) Derivatives designated in cash flow hedging relationships: Interest rate contracts Loss recognized in other comprehensive loss, net of tax $ (39,363 ) $ (8,594 ) Loss reclassified from accumulated other comprehensive loss 1 Interest expense $ (838 ) $ (81 ) Interest expense, net $ 3,698 $ 5,464 1 At March 31, 2020, approximately $8.3 million of net losses are expected to be reclassified into earnings over the next 12 months. However, this expected amount to be reclassified into earnings is subject to volatility as the ultimate amount recognized in earnings is based on the market LIBOR rate at the time of cash settlement.

The fair value of interest rate swaps are determined using a discounted cash flow analysis on the expected cash flows of each derivative. The analysis reflects the contractual terms of the derivatives, including the period to maturity and uses observable market-based inputs, including interest rate forward curves. The fair value of our long-term debt is estimated based upon quoted market prices for similar debt issues or estimated based on average market prices for comparable debt when there is no quoted market price. The contract value of our company owned life insurance is based on the amount at which it could be redeemed and, accordingly, approximates fair value. We believe that our other financial instruments, including cash and cash equivalents, receivables and payables have net carrying values that approximate their fair values with only insignificant differences. This is primarily due to the short-term nature of these instruments.

The dividend equivalents will be converted into additional RSUs that will vest in the same manner as the underlying RSUs to which they relate. Therefore, the shares are not considered participating securities. The terms of the awards state that the RSUs will vest in a given time period of one to three years and the terms of certain awards follow a vesting schedule within the given time period. The fair value of RSUs granted equaled our common share price on the date of grant factoring in any required post-vesting holding periods. The weighted average fair value of all RSUs granted during the three months ended March 31, 2020 was $42.16.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 12. INCOME TAXES As a real estate investment trust (REIT), we generally are not subject to federal and state corporate income taxes on income of the REIT that we distribute to our shareholders. We conduct certain activities through our taxable REIT subsidiaries (TRS), which are subject to corporate level federal and state income taxes. These taxable activities are principally comprised of our wood products manufacturing operations and certain real estate investments. Therefore, income tax expense or benefit is primarily due to income or loss of the TRS, as well as permanent book versus tax differences. During the three months ended March 31, 2020 we recorded an income tax benefit of approximately $11.2 million associated with the $43.0 million pension settlement charge. Additionally, we recorded an increase in deferred tax assets of $6.8 million associated with the $26.2 million remeasurement of our pension plan obligations. See Note 14: Pension and Other Postretirement Employee Benefits for further details. During the three months ended March 31, 2019 we recorded a reduction to deferred tax liabilities and an increase to income taxes payable of $15.8 million related to the sale of the Deltic MDF facility.

General Discussion Of Pension And Other Postretirement Benefits [Abstract]
Pension and Other Postretirement Employee Benefits	NOTE 14. PENSION AND OTHER POSTRETIREMENT EMPLOYEE BENEFITS In February 2020 we purchased a group annuity contract from an insurance company to transfer $101.1 million of our outstanding pension benefit obligation related to our qualified pension plans to the insurance company. This transaction was funded with plan assets. As a result of the transaction, the insurance company assumed responsibility for annuity administration and benefit payments to select retirees, with no change to their monthly retirement benefit payment amounts. In connection with this transaction we recorded a non-cash pretax settlement charge of $ 43.0 million during the three months ended March 31, 2020 in non-operating expense, net, accelerating the recognition of actuarial losses included in accumulated other comprehensive loss that would have been recognized in future periods. The settlement triggered a remeasurement of plan assets and liabilities. We updated the discount rate used to measure our projected benefit obligation for the qualified pension plans as of February 29, 2020 and to calculate the related net periodic benefit cost for the remainder of 2020 to 2.95% from 3.40%. All other pension assumptions remain unchanged. The net effect of the remeasurement was a reduction in the funded status of our qualified pension plans of approximately $26.2 million, primarily driven by the decrease in the discount rate. The following tables detail the components of net periodic cost (benefit) of our pension plans and other postretirement employee benefits (OPEB): Three Months Ended March 31, Pension OPEB (in thousands) 2020 2019 2020 2019 Service cost $ 2,290 $ 2,021 $ 143 $ 105 Interest cost 3,564 4,539 375 419 Expected return on plan assets (4,586 ) (5,554 ) — — Amortization of prior service cost (credit) 28 53 (319 ) (2,211 ) Amortization of actuarial loss 4,154 3,427 419 307 Net periodic cost (benefit) before pension settlement charge 5,450 4,486 618 (1,380 ) Pension settlement charge 42,988 — — — Total net periodic cost (benefit) $ 48,438 $ 4,486 $ 618 $ (1,380 ) During the three months ended March 31, 2020 and 2019, funding of pension and other postretirement employee benefit plans was $1.5 million and $1.7 million, respectively. Further, as allowed under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) passed in March 2020, we will defer approximately $4.4 million of required 2020 contributions for our qualified pension plans until 2021.

Subsequent Events	NOTE 16. SUBSEQUENT EVENT On March 11, 2020, the World Health Organization declared the novel strain of coronavirus (COVID-19) a global pandemic and recommended containment and mitigation measures worldwide. On March 13, 2020, the United States declared a national emergency concerning the outbreak, and all states and several municipalities have declared public health emergencies. Our Timberlands and Wood Products businesses have been deemed an essential business in states that have issued stay-at-home orders and as such, we plan to continue to operate each of our businesses at full capacity where market conditions allow while maintaining the health and safety of our employees, contractors, suppliers and customers. In our Wood Products segment, our industrial grade plywood product line has been more adversely impacted. As a result of decreased demand, we temporarily suspended operations at our St. Maries, Idaho industrial plywood facility beginning April 20, 2020. We will re-start our plywood facility when we have received enough orders to justify re-opening the facility, which we estimate to be sometime in May 2020. Further, we expect the economic impacts from COVID-19 to negatively impact our Chenal Valley real estate development. Additionally, we anticipate our current cash balances, cash flows from operations and our available sources of liquidity will be sufficient to meet our cash requirements. At March 31, 2020 we had approximately $79.5 million in cash and cash equivalents and availability of $379.0 million on our revolving line of credit. As the impact of COVID-19 pandemic on the economy and our operations evolves, we will continue to assess our liquidity needs. In the event of a sustained market deterioration, we may be required to assess liquidity options available to us, including accessing our revolving line of credit, reassessing our capital allocation strategy including the funding of our quarterly dividend, or take appropriate actions such as only proceeding with operating and capital spending that is critical.
