Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	DESCRIPTION OF BUSINESS Alexander & Baldwin, Inc. ("A&B" or the "Company") is headquartered in Honolulu, Hawai`i and operates three segments: Commercial Real Estate ("CRE"); Land Operations; and Materials & Construction ("M&C").

Accounting Policies [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The interim condensed consolidated financial statements are unaudited. Because of the nature of the Company's operations, the results for interim periods are not necessarily indicative of results to be expected for the year. While these condensed consolidated financial statements reflect all normal recurring adjustments that are, in the opinion of management, necessary for fair presentation of the results of the interim period, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("GAAP") for complete financial statements. Therefore, the interim condensed consolidated financial statements should be read in conjunction with the consolidated balance sheets as of December 31, 2017 and 2016 , and the related consolidated statements of operations, comprehensive income (loss), equity, and cash flows for each of the three years in the period ended December 31, 2017 and the notes thereto included in the Company's Annual Report filed on Form 10-K for the year ended December 31, 2017 (" 2017 Form 10-K"), and other subsequent filings with the U.S. Securities and Exchange Commission. Reclassifications: Certain amounts in the Company's prior period condensed consolidated financial statements have been reclassified to conform to the current period presentation. In connection with the adoption of Accounting Standards Update ("ASU") No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , transfers to or from restricted cash which have previously been shown in the Company's investing activities section of the condensed consolidated statements of cash flows are now required to be shown as part of the total change in cash, cash equivalents and restricted cash in the condensed consolidated statements of cash flows. This change resulted in a decrease in cash flows used in investing activities of $6.6 million during the nine months ended September 30, 2017 . Additionally, the Company disaggregated and separately presented long-term costs of its employee benefit plans within Accrued retirement benefits in its condensed consolidated balance sheet. In connection with such presentation, the Company reclassified $2.8 million of accrued costs related to its non-qualified benefit plans from Other non-current liabilities and $19.9 million of accrued costs related to its qualified pension and post-retirement benefit plans from Accrued pension and post-retirement benefits in its condensed consolidated balance sheet as of December 31, 2017 . Rounding: Amounts in the condensed consolidated financial statements and notes are rounded to the nearest tenth of a million. Accordingly, a recalculation of some per-share amounts and percentages, if based on the reported data, may result in differences. Significant Accounting Policies: The Company's significant accounting policies are described in Note 2 to the consolidated financial statements included in Item 8 of the Company's 2017 Form 10-K. Changes to significant accounting policies are included herein. Revenue recognition Sources of revenue for the Company primarily include commercial property rentals, sales of real estate, real estate development projects, material sales and paving construction projects. The Company generates revenue from three distinct business segments: Commercial Real Estate: The Commercial Real Estate segment owns, operates, leases, and manages a portfolio of retail, office, and industrial properties in Hawai`i; it also leases urban land in Hawai`i to third-party lessees. Commercial Real Estate revenue is recognized on a straight-line basis over the term of the corresponding lease. Also included in rental revenues are certain tenant reimbursements and percentage rents determined in accordance with the terms of the lease. The Company records revenue for real estate taxes paid by its tenants for commercial properties with an offsetting expense in Cost of Commercial Real Estate in the accompanying condensed consolidated statement of operations, as the Company has concluded it is the primary obligor. Land Operations: Revenues from sales of real estate are recognized at the point in time when control of the underlying goods is transferred to the customer and the payment is due (generally on the closing date). For certain development projects the Company will use a percentage of completion for revenue recognition. Under this method, the amount of revenue recognized is based on the development costs that have been incurred throughout the reporting period as a percentage of total expected developments associated with the development project. Materials & Construction: Revenue from the Materials & Construction segment is primarily generated from material sales and paving and construction contracts. The recognition of revenue is based on the underlying terms of the transactions. Materials : Revenues from material sales, which include basalt aggregate, liquid asphalt and hot mix asphalt, are usually recognized at a point in time when control of the underlying goods is transferred to the customers (generally this occurs when materials are picked up by customers or their agents) and when the Company has a present right to payment for materials sold. Construction : The Company's construction contracts generally contain a single performance obligation as the promise to transfer individual goods or services are not separately identifiable from other promises in the contracts and is, therefore, not distinct. Revenue is earned from construction contracts over a period of time as control is continuously transferred to customers. Construction contracts can generally be categorized into two types of contracts with customers based on the respective payment terms; either lump sum or unit priced. Lump sum contracts require the total amount of work be performed under a single fixed price irrespective of actual quantities or actual costs. Earnings on both unit price contracts and lump sum fixed-price paving contracts are recognized using the percentage of completion, cost-to-cost, input method as it is able to faithfully depict the transfer of control of the underlying assets to the customer. Certain construction contracts include retainage provisions. The balances billed but not paid by customers pursuant to these provisions generally become due upon completion and acceptance of the project work or products by the owners. The Company deems its contract prices reflective of the standalone selling prices of the underlying goods and services since the contracts are required to go through a competitive bidding process. The Company recognizes revenue on a net basis excluding indirect taxes, such as sales tax and value added tax collected from customers and remitted to government authorities. Interest and other income (expense), net Interest and other income (expense), net is primarily comprised of a net gain on the sale of the Company's joint venture interest in the Ka Milo real estate development-for-sale project, the non-service cost components of pension and postretirement benefit expense and interest income. For the three and nine months ended September 30, 2018 and 2017 , Interest and other income (expense), net included the following: Three Months Ended September 30, Nine Months Ended September 30, (in millions) 2018 2017 2018 2017 Pension and postretirement benefit expense $ (0.7 ) $ (1.7 ) $ (2.2 ) $ (3.1 ) Interest income 0.3 1.6 0.5 3.9 Sale of Ka Milo joint venture interest 4.2 — 4.2 — Other income (expense) — (0.1 ) — (0.2 ) Interest and other income (expense), net $ 3.8 $ (0.2 ) $ 2.5 $ 0.6 Interest costs on developments and major redevelopments are capitalized as part of real estate development and redevelopment projects that have not yet been placed into service. Capitalization of interest commences when development activities and expenditures begin and end upon completion, which is when the asset is ready for its intended use. Capitalized interest costs related to development activities were $0.4 million and $0.8 million for the nine months ended September 30, 2018 and 2017 , respectively. Recently adopted accounting pronouncements In May 2014, Financial Accounting Standards Board (the "FASB") issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09") to provide guidance for revenue recognition and has superseded the revenue recognition requirements in FASB Accounting Standards Codification ("ASC") 605, as well as most industry-specific guidance. Under ASU 2014-09, revenue is recognized when a customer obtains control of the promised goods or services in an amount that reflects the consideration the entity expects to be entitled to in exchange for those goods or services. The Company adopted the provisions of ASU 2014-09 as of January 1, 2018 using the modified retrospective transition method and applied ASU 2014-09 to those contracts that were not completed as of January 1, 2018 and whose revenue was historically accounted for under ASC 605. The cumulative impact of the adoption was a net reduction to other assets and distributions in excess of retained earnings of $1.4 million as of January 1, 2018. In accordance with ASU 2014-09, the disclosure of the impact of adoption to our condensed consolidated balance sheet was as follows (in millions): Balance as of December 31, 2017 Impact of adoption Balance as of January 1, 2018 Other Assets $ 56.2 $ (1.4 ) $ 54.8 Distributions in excess of accumulated earnings $ (473.0 ) $ (1.4 ) $ (474.4 ) The adoption of ASU 2014-09 did not significantly impact the Company's revenue recognition treatment for its Materials & Construction business segment due to the short term duration of the Company's construction contracts. The Company's Commercial Real Estate business segment recognizes its revenue under the accounting framework of ASC 840, Leases and is therefore excluded from the scope of ASU 2014-09. In May 2017, the FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting . The guidance clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The adoption of this standard did not have an impact on the Company's financial position or results of operations. Recently issued accounting pronouncements In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. The guidance replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. This ASU is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2019. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 requires the identification of arrangements that should be accounted for as leases by lessees. In general, lease arrangements exceeding a twelve month term must now be recognized as assets and liabilities on the balance sheet of the lessee. Under ASU 2016-02, a right-of-use asset and lease obligation will be recorded for all leases, whether operating or financing, while the income statement will reflect lease expense for operating leases and amortization/interest expense for financing leases. The balance sheet amount recorded for existing leases at the date of adoption of ASU 2016-02 must be calculated using the applicable incremental borrowing rate at the date of adoption. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2018. The FASB has subsequently issued other related ASUs, which amend ASU 2016-02 to provide transition practical expedients that an entity may elect to apply and other guidance. The Company is currently in the process of finalizing its assessment of the inventory of its leases that will be impacted by the adoption. The Company does not expect the adoption of the new guidance to have a material impact on the accounting treatment and disclosures of the Company's leases. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. The guidance amends the hedge accounting model in ASC 815 to enable entities to better portray the economics of their risk management activities in the financial statements and enhance the transparency and understandability of hedge results. The amendments expand an entity's ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. This ASU eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted in any interim period or fiscal year before the effective date. For cash flow and net investment hedges existing at the date of adoption, entities will apply the new guidance using a modified retrospective approach (i.e., with a cumulative effect adjustment recorded to the opening balance of retained earnings as of the initial application date). The guidance provides transition relief to make it easier for entities to apply certain amendments to existing hedges (including fair value hedges) where the hedge documentation needs to be modified. The presentation and disclosure requirements apply prospectively. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . The guidance gives entities the option to reclassify tax effects stranded in accumulated other comprehensive income as a result of tax reform to retained earnings. The FASB also gives entities the option to apply the guidance retrospectively or in the period of adoption. When adopted, the standard requires all entities to make new disclosures, regardless of whether they elect to reclassify stranded amounts. Entities are required to disclose whether or not they elected to reclassify the tax effects related to the Tax Cuts and Jobs Act of 2017 as well as their policy for releasing income tax effects from accumulated OCI. This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Entities are able to early adopt the guidance in any interim or annual period for which financial statements have not yet been issued and apply it either (1) in the period of adoption or (2) retrospectively to each period in which the income tax effects of the Tax Cuts and Jobs Act of 2017 related to items in accumulated OCI are recognized. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures. In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting . The guidance expands the scope of ASC 718 to include share-based payment transactions with the exception of specific guidance related to the attribution of compensation cost. The guidance also clarifies that any share-based payment awards granted in conjunction with selling goods or services to customers should be evaluated under ASC 606. This ASU is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The Company is currently assessing the impact that adopting this new standard will have on its consolidated financial statements and footnote disclosures. In August 2018, the FASB issued ASU 2018-13, Changes to the Disclosure Requirements for Fair Value Measurement . The guidance amends and removes several disclosure requirements including the valuation processes for Level 3 fair value measurements. This ASU also modifies some disclosure requirements and requires additional disclosures for changes in unrealized gains and losses included n other comprehensive income for recurring Level 3 fair value measurements and requires the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This ASU is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company is currently assessing the impact that adopting this new standard will have on its consolidated financial statements and footnote disclosures. In August 2018, the FASB issued ASU 2018-14, Changes to the Disclosure Requirements for Defined Benefit Plans . The guidance clarifies current disclosures and removes several disclosure requirements including accumulated other comprehensive income expected to be recognized over the next fiscal year and amount and timing of plan assets expected to be returned to the employer. This ASU also requires additional disclosures for the weighted-average interest crediting rates for cash balance plans and explanations for significant gains and losses related to changes in the benefit plan obligation. This ASU is effective for fiscal years beginning after December 15, 2020. The Company is currently assessing the impact that adopting this new standard will have on its consolidated financial statements and footnote disclosures.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Commitments, Guarantees and Contingencies: Commitments and financial arrangements not recorded on the Company's condensed consolidated balance sheet, excluding lease commitments that are disclosed in Note 9 of the Company's 2017 Form 10-K, included the following (in millions) as of September 30, 2018 : Standby letters of credit (a) $ 11.8 Bonds (b) $ 463.7 (a) Consists of standby letters of credit, issued by the Company’s lenders under the Company’s revolving credit facilities, and relate primarily to the Company’s real estate activities. In the event the letters of credit are drawn upon, the Company would be obligated to reimburse the issuer of the letter of credit. (b) Represents bonds related to construction and real estate activities in Hawai`i. Approximately $437.7 million represents the face value of construction bonds issued by third party sureties (bid, performance and payment bonds) and the remainder is related to commercial bonds issued by third party sureties (permit, subdivision, license and notary bonds). In the event the bonds are drawn upon, the Company would be obligated to reimburse the surety that issued the bond for the amount of the bond, reduced for the work completed to date. Indemnity Agreements: For certain real estate joint ventures, the Company may be obligated under bond indemnities to complete construction of the real estate development if the joint venture does not perform. These indemnities are designed to protect the surety in exchange for the issuance of surety bonds that cover joint venture construction activities, such as project amenities, roads, utilities, and other infrastructure, at its joint ventures. Under the indemnities, the Company and its joint venture partners agree to indemnify the surety bond issuer from all losses and expenses arising from the failure of the joint venture to complete the specified bonded construction. The maximum potential amount of aggregate future payments is a function of the amount covered by outstanding bonds at the time of default by the joint venture, reduced by the amount of work completed to date. The recorded amounts of the indemnity liabilities were not material individually or in the aggregate. The Company is a guarantor of indebtedness for certain of its unconsolidated joint ventures' borrowings with third party lenders, relating to the repayment of construction loans and performance of construction for the underlying project. As of September 30, 2018 , the Company's limited guarantees on indebtedness related to one of its unconsolidated joint ventures totaled $3.1 million . Other than obligations described above and those described in the Company's 2017 Form 10-K, obligations of the Company's joint ventures do not have recourse to the Company and the Company's "at-risk" amounts are limited to its investment. Legal Proceedings and Other Contingencies: A&B owns 16,000 acres of watershed lands in East Maui. A&B also held four water licenses to another 30,000 acres owned by the State of Hawai`i in East Maui. The last of these water license agreements expired in 1986, and all four agreements were then extended as revocable permits that were renewed annually. In 2001, a request was made to the State Board of Land and Natural Resources (the "BLNR") to replace these revocable permits with a long-term water lease. Pending the conclusion by the BLNR of this contested case hearing on the request for the long-term lease, the BLNR has kept the existing permits on a holdover basis. Three parties filed a lawsuit on April 10, 2015 (the "4/10/15 Lawsuit") alleging that the BLNR has been renewing the revocable permits annually rather than keeping them in holdover status. The lawsuit asks the court to void the revocable permits and to declare that the renewals were illegally issued without preparation of an environmental assessment ("EA"). In December 2015, the BLNR decided to reaffirm its prior decisions to keep the permits in holdover status. This decision by the BLNR is being challenged by the three parties. In January 2016, the court ruled in the 4/10/15 Lawsuit that the renewals were not subject to the EA requirement, but that the BLNR lacked legal authority to keep the revocable permits in holdover status beyond one year . The court has allowed the parties to make an immediate appeal of this ruling. In May 2016, the Hawai`i State Legislature passed House Bill 2501, which specified that the BLNR has the legal authority to issue holdover revocable permits for the disposition of water rights for a period not to exceed three years. The governor signed this bill into law as Act 126 in June 2016. Pursuant to Act 126, the annual authorization of the existing holdover permits was sought and granted by the BLNR in December 2016 and November 2017. Hawaii Commercial & Sugar Company ("HC&S") used water from four streams in Central Maui ("Na Wai Eha") to irrigate its agricultural lands in Central Maui. Beginning in 2004, the Water Commission began proceedings to establish IIFS for the Na Wai Eha streams. Before the IIFS proceedings were concluded, the Water Commission designated Na Wai Eha as a surface water management area, meaning that all uses of water from these streams required water use permits issued by the Water Commission. Following contested case proceedings, the Water Commission established IIFS in 2010, but that decision was appealed, and the Hawai`i Supreme Court remanded the case to the Water Commission for further proceedings. The parties to the IIFS contested case settled the case in 2014. Thereafter, proceedings for the issuance of water use permits commenced with over 100 applicants, including HC&S, vying for permits. While the water use permit proceedings were ongoing, A&B announced the cessation of sugar cane cultivation in 2016. This announcement triggered a re-opening and reconsideration of the 2014 IIFS decision. Contested case proceedings were held to simultaneously reconsider the IIFS, determine appurtenant water rights, and consider applications for water use permits. Based on those proceedings, the Hearing Officer issued his recommendation to the Water Commission on November 1, 2017. The Commission has not yet issued its decision. If the Company is not permitted to use sufficient quantities of stream waters, it would have a material adverse effect on the Company's pursuit of a diversified agribusiness model in subsequent years and the value of the Company's agricultural lands. A&B is a party to, or may be contingently liable in connection with, other legal actions arising in the normal conduct of its businesses, the outcomes of which, in the opinion of management after consultation with counsel, would not have a material effect on A&B's consolidated financial statements as a whole.

Earnings Per Share [Abstract]
Earnings Per Share (“EPS”)	EARNINGS PER SHARE ("EPS") Basic earnings per common share excludes dilution and is calculated by dividing net earnings allocated to common shares by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share is calculated by dividing net earnings allocated to common shares by the weighted-average number of common shares outstanding for the period, as adjusted for the potential dilutive effect of non-participating share-based awards as well as adjusted by the number of additional shares, if any, that would have been outstanding had the potentially dilutive common shares been issued. The following table provides a reconciliation of income (loss) from continuing operations to income (loss) from continuing operations available to A&B shareholders and net income (loss) available to A&B shareholders (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Income (loss) from Continuing Operations $ 15.8 $ 7.4 $ 66.2 $ 16.0 Less: Income (loss) attributable to noncontrolling interest (0.8 ) (0.5 ) (1.4 ) (1.7 ) Income (loss) from continuing operations attributable to A&B shareholders 15.0 6.9 64.8 14.3 Undistributed earnings allocated to redeemable noncontrolling interest — 0.5 — 1.2 Income (loss) from continuing operations available to A&B shareholders 15.0 7.4 64.8 15.5 Income (loss) from discontinued operations available to A&B shareholders, net of income taxes (0.2 ) (0.8 ) (0.2 ) 2.4 Net income (loss) available to A&B shareholders $ 14.8 $ 6.6 $ 64.6 $ 17.9 The number of shares used to compute basic and diluted earnings per share is as follows (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Denominator for basic EPS - weighted average shares outstanding 72.0 49.2 70.2 49.1 Effect of dilutive securities: Non-participating stock options and restricted stock unit awards 0.4 0.4 0.4 0.5 Special Distribution — — 1.8 — Denominator for diluted EPS - weighted average shares outstanding 72.4 49.6 72.4 49.6 There were 0.1 million shares of anti-dilutive securities outstanding during the three and nine months ended September 30, 2018 .

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS The fair value of the Company's cash and cash equivalents, accounts receivable and short-term borrowings approximate their carrying values due to the short-term nature of the instruments. The fair value of the Company's long-term notes receivable is estimated using a discounted cash flow analysis in which the Company uses unobservable inputs such as market interest rates determined by the loan to value and market capitalization rates related to the underlying collateral at which management believes similar loans would be made and classified as Level 3 in the fair value hierarchy. The fair value of these notes approximates the carrying amount of $16.4 million at September 30, 2018 . The fair value and carrying amount of these notes was immaterial at December 31, 2017 . The carrying amount and fair value of the Company's debt at September 30, 2018 was $778.4 million and $763.0 million , respectively, and $631.2 million and $642.3 million at December 31, 2017 respectively. The fair value of debt is calculated by discounting the future cash flows of the debt at rates based on instruments with similar risk, terms and maturities as compared to the Company's existing debt arrangements (Level 2). The Company carries its interest rate swaps at fair value. See Note 16 for fair value information regarding the Company's derivative instruments.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES For the prior taxable years, the Company has filed a consolidated federal income tax return, which includes all of its wholly owned subsidiaries. On October 15, 2018, the Company filed its 2017 Form 1120-REIT with the Internal Revenue Service. The Company's taxable REIT subsidiary ("TRS") filed separately as a C corporation. The Company also files separate income tax returns in various states. The Company completed the necessary preparatory work and obtained the necessary approvals such that the Company believes it has been organized and operates in a manner that enables it to qualify, and continue to qualify, as a REIT for federal income tax purposes. As a result of the Company's conversion to a REIT, the effective tax rate for the three and nine months ended September 30, 2018 differed from the effective tax rate for the same periods in 2017. For the three months ended September 30, 2018 and 2017 , the Company recorded a reduction to the carrying value of its solar tax equity investments of $0.1 million and $0.4 million , respectively. For the nine months ended September 30, 2018 and 2017 , the Company recorded a reduction of $0.4 million and $2.6 million , respectively, in "Reduction in Solar Investments, net" in the accompanying condensed consolidated statements of operations. The Company recognizes accrued interest and penalties on income taxes as a component of income tax expense. As of September 30, 2018 , accrued interest and penalties were not material.

In connection with the TRC Acquisition, the Company assumed a $62.0 million mortgage secured by Laulani Village that matures on May 1, 2024. The note bears interest at 3.93% and requires monthly interest payments of approximately $0.2 million until May 2020 and principal and interest payments of approximately $0.3 million thereafter. On February 26, 2018, the Company entered into an agreement with Wells Fargo Bank, National Association and a syndicate of other financial institutions that provides for a $50 million term loan facility ("Wells Fargo Term Facility" or "Bank Syndicated Loan"). The Company also drew $50 million under the Wells Fargo Term Facility on February 26, 2018 and used such term loan proceeds to repay amounts that were borrowed under the Company's Revolving Credit Facility. Borrowings under the Wells Fargo Term Facility bear interest at a stated rate, as defined, plus a margin that is determined using a leverage based pricing grid. On April 18, 2018, the Company completed an agreement with Prudential Investment Management, Inc. and its affiliates to refinance its previously existing term loan of $62.5 million that bore interest at 3.90% and matured in 2024, which resulted in three separate term loans: $10.0 million at a fixed interest rate of 4.66% maturing in 2025; $34.5 million at a fixed interest rate of 4.81% maturing in 2027; and $18.0 million at a fixed interest rate of 4.89% maturing in 2028. On September 5, 2018, one of the Company’s subsidiaries GLP Asphalt LLC entered into a Third Amended Credit Agreement with Wells Fargo Bank, National Association, which amended and extended its existing $30 million committed revolving credit facility ("GLP Asphalt Revolving Credit Facility"). The GLP Asphalt Revolving Credit Facility maturity was extended to October 5, 2020. Additionally, the interest rate was reduced by 25 basis points and a fee of 20 basis points on the unused amount of the GLP Asphalt Revolving Credit Facility has been added. All other terms of the Revolving Credit Facility remain substantially unchanged. Subsequent to September 30, 2018 the interest rates for all Prudential Notes and the AIG Note increased by 20 basis points based on a leverage based ratio maximum requirement. The 20 basis point increase shall be in effect until the leverage based ratio hurdle has been achieved.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	DERIVATIVE INSTRUMENTS The Company is exposed to interest rate risk related to its floating rate interest debt. The Company balances its cost of debt and exposure to interest rates primarily through its mix of fixed and floating rate debt. From time to time, the Company may use interest rate swaps to manage its exposure to interest rate risk. Cash Flow Hedges of Interest Rate Risk During 2016, the Company entered into an interest rate swap agreement with a notional amount of $60.0 million which was designated as a cash flow hedge. The Company structured the interest rate swap agreement to hedge the variability of future interest payments due to changes in interest rates with regards to the Company's long-term debt. A summary of the key terms related to the Company's outstanding cash flow hedge as of September 30, 2018 , is as follows (dollars in millions): Effective Maturity Fixed Interest Notional Amount at Fair Value at Classification on Date Date Rate September 30, 2018 September 30, 2018 December 31, 2017 Balance Sheet 4/7/2016 8/1/2029 3.14% $ 60.0 $ 5.8 $ 2.8 Other assets The Company assessed the effectiveness of the cash flow hedge at inception and will continue to do so on an ongoing basis. The effective portion of the changes in fair value of the cash flow hedge is recorded in accumulated other comprehensive income (loss) and subsequently reclassified into interest expense as interest is incurred on the related-variable rate debt. When ineffectiveness exists, the ineffective portion of changes in fair value of the cash flow hedge is recognized in earnings in the period affected. Non-designated Hedges As of September 30, 2018 , the Company has one interest rate swap that has not been designated as a cash flow hedge whose key terms are as follows (dollars in millions): Effective Maturity Fixed Interest Notional Amount at Fair Value at Classification on Date Date Rate September 30, 2018 September 30, 2018 December 31, 2017 Balance Sheet 1/1/2014 9/1/2021 5.95% $ 10.6 $ (0.5 ) $ (0.9 ) Other non-current liabilities During the nine months ended September 30, 2018 , the Company terminated an interest rate swap that was not designated as a cash flow hedge. The interest rate swap was classified as Other non-current liabilities on the consolidated balance sheet and had a fair value of $0.3 million as of December 31, 2017 . The following table represents the pre-tax effect of the derivative instruments in the Company's condensed consolidated statement of comprehensive income (loss) (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Derivatives in Designated Cash Flow Hedging Relationships: Amount of (gain) loss recognized in OCI on derivatives (effective portion) $ (0.6 ) $ 0.2 $ (3.0 ) $ 0.8 Amounts of (gain) loss reclassified from accumulated OCI into earnings under "interest expense" (ineffective portion and amount excluded from effectiveness testing) $ — $ (0.1 ) $ — $ (0.4 ) The Company records gains or losses related to interest rate swaps that have not been designated as cash flow hedges in interest expense in its condensed consolidated statements of operations, and the amounts were immaterial during each of the three and nine months ended September 30, 2018 and 2017 . The Company measures all of its interest rate swaps at fair value. The fair values of the Company's interest rate swaps (Level 2) are based on the estimated amounts that the Company would receive or pay to terminate the contracts at the reporting date and are determined using interest rate pricing models and interest rate related observable inputs.

Revenue from Contract with Customer [Abstract]
Revenues	REVENUES The Company recognizes revenue when control of promised goods or services is transferred to the customer at an amount that reflects the consideration which the Company expects to be entitled to in exchange for those goods or services. The Company disaggregates revenue from contracts with customers by revenue type as the Company believes it best depicts how the nature, amount, timing and uncertainty of the Company's revenue and cash flows are affected by economic factors. Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 1 2018 2017 1 Revenues: Commercial real estate 2 $ 35.9 $ 33.9 $ 104.9 $ 101.4 Land Operations: Development sales revenue 9.0 1.5 42.8 6.1 Unimproved/other property sales revenue 9.1 15.4 11.5 21.4 Other operating revenue 5.9 5.7 18.3 18.2 Land Operations 24.0 22.6 72.6 45.7 Materials & Construction 3 59.5 55.0 167.3 155.7 Total revenues $ 119.4 $ 111.5 $ 344.8 $ 302.8 1 As discussed in Note 2, prior period amounts have not been adjusted under the modified retrospective method. 2 As discussed in Note 2, Commercial Real Estate revenue is not in scope under ASU 2014-09 however is presented here for completeness. 3 Materials & Construction included $4.5 million and $13.9 million of revenue not in scope under ASU 2014-09 for the three and nine months ended September 30, 2018 , respectively. The total amount of contract consideration allocated to either wholly unsatisfied or partially satisfied performance obligations was $157.4 million as of the nine months ended September 30, 2018 . The Company expects to recognize as revenue approximately 25% - 30% of the remaining contract consideration allocated to either wholly unsatisfied or partially satisfied performance obligations in 2018, with the remaining recognized thereafter. The Company has elected the practical expedient provided in ASU 2014-09 to not disclose information about remaining performance obligations that have original expected durations of one year or less. In addition, the Company has elected the transition practical expedient in ASU 2014-09 to not disclose the amount of the transaction price allocated to the remaining performance obligations and an explanation of when the Company expects to recognize that amount as revenue for the nine months ended September 30, 2018 . The Company has elected these practical expedients as the majority of its wholly, or partially, unfulfilled performance obligations are expected to be recognized in less than one year . CONTRACT BALANCES Timing of revenue recognition may differ from the timing of invoicing to customers. Costs and estimated earnings in excess of billings represent amounts earned and reimbursable under contracts but have a conditional right for billing and payment such as achievement of milestones or completion of the project. When events or conditions indicate that it is probable that the amounts outstanding become unbillable, the transaction price and associated contract asset is reduced. Billings in excess of costs and estimated earnings are billings to customers on contracts in advance of work performed, including advance payments negotiated as a contract condition. Generally, unearned project-related costs will be earned over the next twelve months. The following table provides information about receivables, contract assets and contract liabilities from contracts with customers: Beginning Balance as of Ending Balance as of (in millions) January 1, 2018 September 30, 2018 Accounts receivable, net $ 34.1 $ 48.7 Contracts retention $ 13.2 $ 11.6 Costs and estimated earnings in excess of billings on uncompleted contracts $ 20.2 $ 9.6 Current deferred revenue $ 0.9 $ 2.1 Billings in excess of costs and estimated earnings on uncompleted contracts $ 5.7 $ 3.6 Long term deferred revenue $ 2.5 $ 1.8 As of the nine months ended September 30, 2018 , the Company recognized revenue of $3.5 million related to the Company's contract liabilities reported as of January 1, 2018.

Basis of Presentation (Policies

Basis of Presentation (Policies)	9 Months Ended
	Sep. 30, 2018
Accounting Policies [Abstract]
Reclassifications	Reclassifications: Certain amounts in the Company's prior period condensed consolidated financial statements have been reclassified to conform to the current period presentation. In connection with the adoption of Accounting Standards Update ("ASU") No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , transfers to or from restricted cash which have previously been shown in the Company's investing activities section of the condensed consolidated statements of cash flows are now required to be shown as part of the total change in cash, cash equivalents and restricted cash in the condensed consolidated statements of cash flows. This change resulted in a decrease in cash flows used in investing activities of $6.6 million during the nine months ended September 30, 2017 . Additionally, the Company disaggregated and separately presented long-term costs of its employee benefit plans within Accrued retirement benefits in its condensed consolidated balance sheet. In connection with such presentation, the Company reclassified $2.8 million of accrued costs related to its non-qualified benefit plans from Other non-current liabilities and $19.9 million of accrued costs related to its qualified pension and post-retirement benefit plans from Accrued pension and post-retirement benefits in its condensed consolidated balance sheet as of December 31, 2017 .
Rounding	Rounding: Amounts in the condensed consolidated financial statements and notes are rounded to the nearest tenth of a million. Accordingly, a recalculation of some per-share amounts and percentages, if based on the reported data, may result in differences.
Revenue Recognition - Commercial Real Estate	Commercial Real Estate: The Commercial Real Estate segment owns, operates, leases, and manages a portfolio of retail, office, and industrial properties in Hawai`i; it also leases urban land in Hawai`i to third-party lessees. Commercial Real Estate revenue is recognized on a straight-line basis over the term of the corresponding lease. Also included in rental revenues are certain tenant reimbursements and percentage rents determined in accordance with the terms of the lease. The Company records revenue for real estate taxes paid by its tenants for commercial properties with an offsetting expense in Cost of Commercial Real Estate in the accompanying condensed consolidated statement of operations, as the Company has concluded it is the primary obligor.
Revenue Recognition	Land Operations: Revenues from sales of real estate are recognized at the point in time when control of the underlying goods is transferred to the customer and the payment is due (generally on the closing date). For certain development projects the Company will use a percentage of completion for revenue recognition. Under this method, the amount of revenue recognized is based on the development costs that have been incurred throughout the reporting period as a percentage of total expected developments associated with the development project. Materials & Construction: Revenue from the Materials & Construction segment is primarily generated from material sales and paving and construction contracts. The recognition of revenue is based on the underlying terms of the transactions. Materials : Revenues from material sales, which include basalt aggregate, liquid asphalt and hot mix asphalt, are usually recognized at a point in time when control of the underlying goods is transferred to the customers (generally this occurs when materials are picked up by customers or their agents) and when the Company has a present right to payment for materials sold. Construction : The Company's construction contracts generally contain a single performance obligation as the promise to transfer individual goods or services are not separately identifiable from other promises in the contracts and is, therefore, not distinct. Revenue is earned from construction contracts over a period of time as control is continuously transferred to customers. Construction contracts can generally be categorized into two types of contracts with customers based on the respective payment terms; either lump sum or unit priced. Lump sum contracts require the total amount of work be performed under a single fixed price irrespective of actual quantities or actual costs. Earnings on both unit price contracts and lump sum fixed-price paving contracts are recognized using the percentage of completion, cost-to-cost, input method as it is able to faithfully depict the transfer of control of the underlying assets to the customer. Certain construction contracts include retainage provisions. The balances billed but not paid by customers pursuant to these provisions generally become due upon completion and acceptance of the project work or products by the owners. The Company deems its contract prices reflective of the standalone selling prices of the underlying goods and services since the contracts are required to go through a competitive bidding process. The Company recognizes revenue on a net basis excluding indirect taxes, such as sales tax and value added tax collected from customers and remitted to government authorities. Revenue recognition Sources of revenue for the Company primarily include commercial property rentals, sales of real estate, real estate development projects, material sales and paving construction projects. The Company generates revenue from three distinct business segments:
Interest Income (Expense)	Interest and other income (expense), net Interest and other income (expense), net is primarily comprised of a net gain on the sale of the Company's joint venture interest in the Ka Milo real estate development-for-sale project, the non-service cost components of pension and postretirement benefit expense and interest income.
Interest Capitalization	Interest costs on developments and major redevelopments are capitalized as part of real estate development and redevelopment projects that have not yet been placed into service. Capitalization of interest commences when development activities and expenditures begin and end upon completion, which is when the asset is ready for its intended use.
New Accounting Pronouncements	Recently adopted accounting pronouncements In May 2014, Financial Accounting Standards Board (the "FASB") issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09") to provide guidance for revenue recognition and has superseded the revenue recognition requirements in FASB Accounting Standards Codification ("ASC") 605, as well as most industry-specific guidance. Under ASU 2014-09, revenue is recognized when a customer obtains control of the promised goods or services in an amount that reflects the consideration the entity expects to be entitled to in exchange for those goods or services. The Company adopted the provisions of ASU 2014-09 as of January 1, 2018 using the modified retrospective transition method and applied ASU 2014-09 to those contracts that were not completed as of January 1, 2018 and whose revenue was historically accounted for under ASC 605. The cumulative impact of the adoption was a net reduction to other assets and distributions in excess of retained earnings of $1.4 million as of January 1, 2018. In accordance with ASU 2014-09, the disclosure of the impact of adoption to our condensed consolidated balance sheet was as follows (in millions): Balance as of December 31, 2017 Impact of adoption Balance as of January 1, 2018 Other Assets $ 56.2 $ (1.4 ) $ 54.8 Distributions in excess of accumulated earnings $ (473.0 ) $ (1.4 ) $ (474.4 ) The adoption of ASU 2014-09 did not significantly impact the Company's revenue recognition treatment for its Materials & Construction business segment due to the short term duration of the Company's construction contracts. The Company's Commercial Real Estate business segment recognizes its revenue under the accounting framework of ASC 840, Leases and is therefore excluded from the scope of ASU 2014-09. In May 2017, the FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting . The guidance clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The adoption of this standard did not have an impact on the Company's financial position or results of operations. Recently issued accounting pronouncements In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. The guidance replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. This ASU is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2019. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 requires the identification of arrangements that should be accounted for as leases by lessees. In general, lease arrangements exceeding a twelve month term must now be recognized as assets and liabilities on the balance sheet of the lessee. Under ASU 2016-02, a right-of-use asset and lease obligation will be recorded for all leases, whether operating or financing, while the income statement will reflect lease expense for operating leases and amortization/interest expense for financing leases. The balance sheet amount recorded for existing leases at the date of adoption of ASU 2016-02 must be calculated using the applicable incremental borrowing rate at the date of adoption. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2018. The FASB has subsequently issued other related ASUs, which amend ASU 2016-02 to provide transition practical expedients that an entity may elect to apply and other guidance. The Company is currently in the process of finalizing its assessment of the inventory of its leases that will be impacted by the adoption. The Company does not expect the adoption of the new guidance to have a material impact on the accounting treatment and disclosures of the Company's leases. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. The guidance amends the hedge accounting model in ASC 815 to enable entities to better portray the economics of their risk management activities in the financial statements and enhance the transparency and understandability of hedge results. The amendments expand an entity's ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. This ASU eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted in any interim period or fiscal year before the effective date. For cash flow and net investment hedges existing at the date of adoption, entities will apply the new guidance using a modified retrospective approach (i.e., with a cumulative effect adjustment recorded to the opening balance of retained earnings as of the initial application date). The guidance provides transition relief to make it easier for entities to apply certain amendments to existing hedges (including fair value hedges) where the hedge documentation needs to be modified. The presentation and disclosure requirements apply prospectively. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . The guidance gives entities the option to reclassify tax effects stranded in accumulated other comprehensive income as a result of tax reform to retained earnings. The FASB also gives entities the option to apply the guidance retrospectively or in the period of adoption. When adopted, the standard requires all entities to make new disclosures, regardless of whether they elect to reclassify stranded amounts. Entities are required to disclose whether or not they elected to reclassify the tax effects related to the Tax Cuts and Jobs Act of 2017 as well as their policy for releasing income tax effects from accumulated OCI. This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Entities are able to early adopt the guidance in any interim or annual period for which financial statements have not yet been issued and apply it either (1) in the period of adoption or (2) retrospectively to each period in which the income tax effects of the Tax Cuts and Jobs Act of 2017 related to items in accumulated OCI are recognized. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures. In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting . The guidance expands the scope of ASC 718 to include share-based payment transactions with the exception of specific guidance related to the attribution of compensation cost. The guidance also clarifies that any share-based payment awards granted in conjunction with selling goods or services to customers should be evaluated under ASC 606. This ASU is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The Company is currently assessing the impact that adopting this new standard will have on its consolidated financial statements and footnote disclosures. In August 2018, the FASB issued ASU 2018-13, Changes to the Disclosure Requirements for Fair Value Measurement . The guidance amends and removes several disclosure requirements including the valuation processes for Level 3 fair value measurements. This ASU also modifies some disclosure requirements and requires additional disclosures for changes in unrealized gains and losses included n other comprehensive income for recurring Level 3 fair value measurements and requires the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This ASU is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company is currently assessing the impact that adopting this new standard will have on its consolidated financial statements and footnote disclosures. In August 2018, the FASB issued ASU 2018-14, Changes to the Disclosure Requirements for Defined Benefit Plans . The guidance clarifies current disclosures and removes several disclosure requirements including accumulated other comprehensive income expected to be recognized over the next fiscal year and amount and timing of plan assets expected to be returned to the employer. This ASU also requires additional disclosures for the weighted-average interest crediting rates for cash balance plans and explanations for significant gains and losses related to changes in the benefit plan obligation. This ASU is effective for fiscal years beginning after December 15, 2020. The Company is currently assessing the impact that adopting this new standard will have on its consolidated financial statements and footnote disclosures.
