Organization, Consolidation and Presentation of Financial Statements [Abstract]
Background and Basis of Presentation	BACKGROUND AND BASIS OF PRESENTATION Description of Business: Alexander & Baldwin, Inc. ("A&B" or the "Company") is a real estate investment trust ("REIT") headquartered in Honolulu, Hawai‘i. The Company operates three segments: Commercial Real Estate; Land Operations; and Materials & Construction. A description of each of the Company's reporting segments is as follows: • Commercial Real Estate ("CRE") functions as a vertically integrated real estate investment company with core competencies in investments and acquisitions (i.e., raising capital, identifying opportunities and acquiring properties); construction and development (i.e., designing and ground-up development of new properties or repositioning and redevelopment of existing properties); in-house leasing and property management (i.e., executing new and renegotiating renewal lease arrangements, managing its properties' day-to-day operations and maintaining positive tenant relationships); and asset management (i.e., maintaining, upgrading and enhancing its portfolio of high-quality improved properties). The segment's preferred asset classes include improved properties in retail and industrial spaces and also urban ground leases. Its focus within improved retail properties, in particular, is on grocery-anchored neighborhood shopping centers that meet the daily needs of Hawai‘i citizens. Through its core competencies and with its experience and relationships in Hawai‘i, the Company seeks to create special places and experiences for Hawai‘i residents as well as providing venues and opportunities for tenants to thrive. Income from this segment is principally generated by owning, operating and leasing real estate assets. • Land Operations involves the management and optimization of the Company's historical landholdings primarily through the following activities: planning and entitlement of real property to facilitate sales; selling undeveloped land; and other operationally-diverse legacy business activities to employ its landholdings at their highest and best use. Financial results from this segment are principally derived from real estate development sales, land parcel sales, income/loss from real estate joint ventures and other legacy business activities. • Materials & Construction ("M&C") operates as Hawai‘i's largest asphalt paving contractor and is one of the state's largest natural materials and infrastructure construction companies. Such activities are primarily conducted through the Company's wholly-owned subsidiary, Grace Pacific LLC ("Grace Pacific"), a materials and construction company in Hawai‘i. Grace Pacific owns hot-mix asphalt plants throughout the state that support its internal paving operations and third-party customers. Grace Pacific also owns and operates a rock quarry and processing plant in Makakilo, Hawai‘i. In addition, Grace Pacific offers a variety of related for-sale and for-rent services including temporary and permanent roadway traffic control (GP Roadway Solutions, Inc. or "GPRS"), structural precast/prestressed concrete (GP/RM Prestress, LLC or "GPRM") and other related products and services. Grace Pacific also holds a 50% interest in an unconsolidated affiliate, Maui Paving, LLC ("Maui Paving"), which operates primarily on the island of Maui. Additional activity in the M&C segment includes its share of the results of operations of an unconsolidated investment, Pohaku Pa‘a LLC ("Pohaku"). Pohaku, through its wholly-owned subsidiaries, operates rock quarries on the islands of Oahu and Maui and sells a wide range of products that include ready-mix concrete, rock and sand aggregates and cultured stone and related products. As of December 31, 2019 , the Company owns a portfolio of commercial real estate improved properties in Hawai‘i consisting of 22 retail centers, ten industrial assets and four office properties, representing a total of 3.9 million square feet of gross leasable area; it also owns a portfolio of ground leases in Hawai‘i representing 153.8 acres as of December 31, 2019 . Basis of Presentation and Principles of Consolidation: The Company presents its financial statements in accordance with accounting principles generally accepted in the United States ("GAAP") as outlined in the Financial Accounting Standard Board ("FASB") Accounting Standards Codification (the "Codification" or "ASC"). The Codification is the single source of authoritative accounting principles applied by nongovernmental entities in the preparation of financial statements in conformity with GAAP. The consolidated financial statements include the accounts of the Company (including all wholly-owned subsidiaries), as well as all other entities in which the Company has a controlling financial interest. Intercompany transactions and balances have been eliminated in consolidation. Significant investments in businesses, partnerships and limited liability companies in which the Company does not have a controlling financial interest, but the Company has the ability to exercise significant influence, are accounted for using the equity method. A controlling financial interest in an entity may be established (i) through the Company holding a majority voting interest or (ii) if the Company is the primary beneficiary of an entity that qualifies as a variable interest entity ("VIE"), as defined in the Codification. The Company evaluates all partnerships, joint ventures and other arrangements with variable interests to determine if the entity or arrangement qualifies as a VIE. VIEs are entities where investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or where equity investors, as a group, lack one of the following characteristics: (a) the power to direct the activities that most significantly impact the entity’s economic performance, (b) the obligation to absorb the expected losses of the entity, or (c) the right to receive the expected returns of the entity. If the entity or arrangement qualifies as a VIE and the Company is determined to be the primary beneficiary, the Company is required to consolidate the assets, liabilities, and results of operations of the VIE. The Company reevaluates whether an entity is a VIE as needed (i.e., when assessing reconsideration events that result in changes in the factors mentioned above) as part of determining if the consolidation or equity method treatment remains appropriate. As of December 31, 2019 , the Company had an interest in various unconsolidated joint ventures that the Company accounts for using the equity method. Other than the obligations described in Note 14. "Commitments and Contingencies," obligations of the Company's joint ventures do not have recourse to the Company and the Company's maximum exposure is limited to its investment. The consolidated financial statements include the results of GPRM, a supplier in the precast concrete industry, and GLP Asphalt, LLC ("GLP"), an importer and distributor of liquid asphalt, which are owned 51% and 70% , respectively. These entities are consolidated because the Company holds a controlling financial interest through its majority voting interest in the entities. The remaining interest in these entities is reported as noncontrolling interest in the consolidated financial statements. Profits, losses and cash distributions are allocated in accordance with the respective operating agreements. Use of Estimates: The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Estimates and assumptions are used for, but not limited to: (i) asset impairments, including intangible assets and goodwill, (ii) litigation and contingencies, (iii) revenue recognition for long-term real estate developments and construction contracts, (iv) pension and postretirement estimates, and (v) income taxes. Future results could be materially affected if actual results differ from these estimates and assumptions. Customer Concentration: A significant portion of Materials & Construction revenue and accounts receivable is generated directly and indirectly from projects administered by the City and County of Honolulu and from the State of Hawai‘i. Reductions in funding of infrastructure projects by these government agencies could reduce our revenue and profits from our M&C segment. Further, although the customer mix of real estate sales in any given period in our Land Operations segment may be diverse in any given period, during the year ended December 31, 2018 , the Land Operations segment recognized $162.2 million of gross profit in connection with the sale of approximately 41,000 acres of Maui agricultural land and 100% of the Company's ownership interest in Central Maui Feedstocks LLC and Kulolio Ranch LLC (collectively referred to as the "Agricultural Land Sale") in December 2018. Reclassifications: During the first quarter of 2019, the Company changed the presentation of its balance sheet to be unclassified in order to be comparable with other REIT peers. The change was applied to all periods presented retrospectively. Previously reported captions for Total assets , Total liabilities and captions within Equity were not impacted. In November 2018, the Securities and Exchange Commission ("SEC") finalized the Disclosure Update Simplification Project, which eliminated Rule 3-15(a)(1) reporting of Gain or Loss on Sale of Properties by REITs. To conform with ASC 360 and the SEC rule change, the Company has classified the gain on dispositions of real estate assets in operating income in the Company’s consolidated statements of operations. The Company reclassified the prior periods to conform to the current year presentation. This change resulted in an increase in operating income of $9.3 million during the year ended December 31, 2017. Rounding: Amounts in the 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.

Accounting Policies [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES Real estate property, net: Real estate property, net primarily represents long-lived physical assets associated with the CRE segment's leasing activity (e.g., improved property leases and ground leases); it also includes landholdings and related assets in the Land Operations segment that the Company holds for either possible future development or future monetization as part of its simplification strategy. The balance primarily consists of land, buildings and improvements and is recorded at cost, net of accumulated depreciation. Expenditures for additions, improvements and other enhancements to real estate properties are capitalized, and minor replacements, maintenance and repairs that do not improve or extend asset lives are charged to expense as incurred. When assets related to real estate properties are retired or otherwise disposed of, the related cost and accumulated depreciation is removed from the accounts and any resulting gain or loss is included in results of operations for the respective period. Certain costs are capitalized related to the development and redevelopment of real estate properties, including pre-construction costs; real estate taxes; insurance; construction costs; and salaries and related costs of personnel directly involved. Additionally, the Company makes estimates as to the probability of certain development and redevelopment projects being completed. If the Company determines the development or redevelopment is no longer probable of completion, the Company expenses all capitalized costs which are not recoverable. Acquisitions of real estate properties: Acquisitions of real estate properties are evaluated to determine if they should be accounted for as asset acquisitions or business combinations. Under current guidance, acquisitions of real estate properties are generally considered asset acquisitions. Under asset acquisition accounting, the Company estimates the fair value of acquired tangible assets (consisting of land, buildings and tenant improvements), identifiable intangible assets and liabilities (consisting of above- and below- market leases and in-place leases), and assumed debt based on an evaluation of available information at the date of the acquisition. Based on these estimates, the purchase consideration is allocated to the acquired assets and assumed liabilities. Transaction costs incurred during the acquisition process are capitalized as a component of the purchase consideration. In estimating the fair value of the tangible and intangible assets acquired, the Company considers information obtained about each property as a result of its due diligence and marketing and leasing activities and uses various valuation methods, such as estimated cash flow projections using appropriate discount and capitalization rates, analysis of recent comparable sales transactions, estimates of replacement costs net of depreciation and other available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. Above-market and below-market lease values are estimated based on the present value (using a discount rate reflecting the risks associated with leases acquired) of the difference between: (i) the contractual amounts to be paid pursuant to the leases negotiated and in-place at the time of acquisition and (ii) management’s estimate of fair market lease rates for the property or an equivalent property, measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the estimated term of any below-market, fixed-rate renewal options for below-market leases. The capitalized above- and below-market lease values are amortized to base rental revenue over the related lease term plus fixed-rate renewal options, as appropriate. The purchase price is further allocated to in-place lease values and tenant relationship values based on management's evaluation of the specific characteristics of the acquired lease portfolio and the Company's overall relationship with the anchor tenants. Such amounts are amortized to expense over the remaining initial lease term (and expected renewal periods for tenant relationships). Real estate developments: Real estate developments represent certain costs capitalized and presented in the Land Operations segment that relate to (i) active real estate development projects intended for sale or (ii) potential future real estate development projects intended for lease that would be part of future CRE segment operations. For potential future real estate development projects intended for lease, when management with the relevant authority has approved expenditures for activities clearly associated with the development and construction of a CRE segment project (generally after all required government agency approvals have been obtained), the capitalized costs associated with such project (i.e., historical cost of land) will be presented as Real estate property, net . Certain costs capitalized relating to active real estate development projects intended for sale may include pre-construction costs (e.g., costs related to land acquisition); construction costs (e.g., grading, roads, water and sewage systems, landscaping and project amenities); direct overhead costs (e.g., utilities, maintenance, insurance and real estate taxes); capitalized interest; and salaries and related costs of personnel directly involved. For development projects, capitalized costs are allocated using the direct method for expenditures that are specifically associated with the unit being sold and the relative-sales-value method for expenditures that benefit the entire project. Direct overhead costs incurred after the development project is substantially complete and ready to be marketed are charged to selling, general and administrative expense as incurred. All indirect overhead costs are charged to selling, general and administrative costs as incurred. Cash flows related to active real estate development projects intended for sale are classified as operating activities. Capitalized Interest: 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 when the asset is substantially complete and ready for its intended use or ready to be marketed. Total interest costs incurred were $34.1 million , $35.9 million , and $26.4 million in 2019 , 2018 and 2017 , respectively. Capitalized interest costs related to development activities were $1.0 million , $0.6 million and $0.8 million in 2019 , 2018 and 2017 , respectively. Other property, net: Other property, net represents all other long-lived physical assets other than those presented in Real estate property, net and Real estate developments. The balance primarily consists of long-lived assets in the M&C segment, but also contains corporate long-lived physical assets and Land Operations long-lived physical assets that are used in other Land Operations activities and are not presented in Real estate property, net or Real estate developments above. Other property, net is stated at cost, net of accumulated depreciation. Expenditures for major renewals and betterments are capitalized. Replacements, maintenance and repairs that do not improve or extend asset lives are charged to expense as incurred. As of December 31, 2019 and 2018 other property, net was as follows (in millions): 2019 2018 Land $ 38.4 $ 42.2 Buildings 19.7 20.4 Asphalt plants, machinery and equipment 105.5 116.7 Water, power and sewer systems 30.6 33.0 Other property improvements 6.8 8.1 Subtotal 201.0 220.4 Accumulated depreciation (76.6 ) (84.9 ) Other property, net $ 124.4 $ 135.5 Depreciation: Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the assets or the units-of-production method for quarry production-related assets. Estimated useful lives of property are as follows: Classification Range of Life (in years) Building and improvements 10 to 40 Leasehold improvements 5 to 10 (lesser of useful life or lease term) Water, power and sewer systems 5 to 50 Asphalt plants, machinery and equipment 2 to 35 Other property improvements 3 to 35 Depreciation expense for the years ended December 31, 2019, 2018 and 2017 was $35.6 million , $32.5 million and $32.3 million , respectively. Intangible Assets: Real estate intangible assets are recorded on the consolidated balance sheets as Real estate intangible assets, net and are generally related to the acquisition of commercial real estate properties. Intangible assets acquired in 2019 , 2018 and 2017 were as follows: 2019 2018 2017 Amount Weighted Average Life (Years) Amount Weighted Average Life (Years) Amount Weighted Average Life (Years) In-place leases $ 23.2 8.2 $ 32.0 12.4 $ 0.2 2.2 Favorable leases 4.3 4.7 6.7 11.7 0.1 1.1 Real Estate intangible assets, net as of December 31, 2019 and 2018 were as follows (in millions): 2019 2018 In-place leases $ 125.2 $ 102.1 Favorable leases 29.0 24.6 Amortization of in-place leases (63.4 ) (53.2 ) Amortization of favorable leases (15.9 ) (13.7 ) Real estate intangible assets, net $ 74.9 $ 59.8 Other intangible assets are included in Prepaid expenses and other assets in the accompanying consolidated balance sheets. As of December 31, 2019 and 2018 , the gross carrying amount of other intangible assets was $20.2 million and $16.3 million , with related accumulated amortization of $7.9 million and $6.5 million , respectively. Aggregate intangible asset amortization expense was $12.5 million , $8.7 million , and $6.0 million for 2019 , 2018 and 2017 , respectively. Estimated amortization expenses related to intangible assets over the next five years are as follows (in millions): Estimated 2020 $ 12.5 2021 10.2 2022 8.4 2023 7.5 2024 5.3 In situations in which a lease or leases with a tenant have been, or are expected to be, terminated early, the Company evaluates the remaining useful lives of depreciable or amortizable assets of the associated assets related to the lease terminated (i.e., tenant improvements, above and below market lease intangibles, in-place lease value and leasing commissions). Based upon consideration of the facts and circumstances surrounding the termination, the Company may accelerate the depreciation and amortization of such associated assets. Cash and Cash Equivalents: Cash equivalents consist of highly liquid investments with a maturity of three months or less at the date of purchase. The Company carries these investments at cost, which approximates fair value. Restricted Cash: The Company's restricted cash balance at December 31, 2018 of $223.5 million primarily consisted of proceeds from §1031 tax-deferred sales held in escrow pending future use to purchase new real estate assets. There were no material amounts of proceeds from §1031 tax-deferred sales in the balance as of December 31, 2019 . Allowance for Doubtful Accounts: Allowances for doubtful accounts are established by management based on estimates of collectability. Estimates of collectability are principally based on an evaluation of the current financial condition of the Company’s customers and their payment history, which are regularly monitored by the Company. The changes in the allowance for doubtful accounts, included on the consolidated balance sheets as an offset to Accounts receivable, net for the years ended December 31, 2019, 2018 and 2017 , were as follows (in millions): Balance at Provision for Bad Debt Write-offs Balance at 2019 $2.0 $1.9 $(1.2) $2.7 2018 $1.4 $1.3 $(0.7) $2.0 2017 $1.0 $1.0 $(0.6) $1.4 As of December 31, 2019 , the Company's allowances for doubtful accounts relate only to accounts receivable in the M&C segment (unrelated to leases). Notes receivable : The Company's notes receivable are recorded at cost within Other receivables on the consolidated balance sheets. Generally, a loans allowance is established when the Company determines that it will be unable to collect any remaining amounts due under the agreement. Inventories: Inventories are stated at the lower of cost (principally average cost, first-in, first-out basis) or net realizable value. Inventories as of December 31, 2019 and 2018 were as follows (in millions): 2019 2018 Asphalt $ 8.0 $ 9.4 Processed rock and sand 6.6 9.5 Work in progress 2.9 4.0 Retail merchandise 2.0 2.0 Parts, materials and supplies inventories 1.2 1.6 Total $ 20.7 $ 26.5 Leases - The Company as Lessee: The Company determines if an arrangement is a lease at inception by considering whether that arrangement conveys the right to use an identified asset for a period of time in exchange for consideration. Operating leases are included in Operating lease right-of-use assets ("ROU assets") and Operating lease liabilities in the Company's consolidated balance sheets. ROU assets and lease liabilities related to finance leases are included in Other property, net and Notes payable and other debt , respectively, in the Company's consolidated balance sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company's leases do not provide an implicit rate and are not readily determinable, the Company uses its incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. ROU assets also include any lease payments made at or before the commencement date and excludes any lease incentives received. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense for lease payments is recognized on a straight-line basis over the lease term. In connection with its application of the lease guidance, the Company has evaluated the lease and non-lease components within its leases where it is the lessee and has elected, for all classes of underling assets, the practical expedient to present lease and non-lease components in its lease agreements as one component. The Company has also elected, for all classes of underlying assets, to not recognize lease liabilities and lease assets for leases with a term of 12 months or less. Goodwill: The Company reviews goodwill for impairment at the reporting unit level annually or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. If the results of the Company's test indicates that a reporting unit's estimated fair value is less than its carrying value, an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to that reporting unit. Refer to Note 22, "Goodwill," for additional detail. Fair Value Measurements: ASC Topic 820, Fair Value Measurements and Disclosures ("ASC 820") , as amended, establishes a fair value hierarchy, which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The hierarchy places the highest priority on unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurements) and assigns the lowest priority to unobservable inputs (Level 3 measurements). The three levels of inputs within the hierarchy are defined as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. If the technique used to measure fair value includes inputs from multiple levels of the fair value hierarchy, the lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy. The Company records its interest rate swaps at fair value. The fair values of the Company's interest rate swaps (Level 2 measurements) 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. See Note 15, "Derivative Instruments," for fair value information regarding the Company's derivative instruments. The fair value of the Company's cash and cash equivalents, accounts receivable, net and short-term borrowings approximate their carrying values due to the short-term nature of the instruments. The fair value of the Company's notes receivable approximates the carrying amount of $15.7 million at December 31, 2019 . The fair value and carrying amount of these notes was $16.3 million at December 31, 2018 . The fair value of these notes 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 a Level 3 measurement in the fair value hierarchy. The carrying amount and fair value of the Company's debt at December 31, 2019 was $704.6 million and $727.3 million , respectively, and $778.1 million and $758.0 million , respectively, at December 31, 2018 . 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 3). During the years ended December 31, 2019, 2018 and 2017 , the Company recorded aggregate impairment charges of $49.7 million , $79.4 million and $22.4 million related to goodwill and/or other long-lived assets. During the year ended December 31, 2018 , the Company recorded an other-than-temporary-impairment charge of $188.6 million related to equity method investments. See further discussion in the respective sections below. The Company has classified the fair value measurements as a Level 3 measurement in the fair value hierarchy because they involve significant unobservable inputs such as cash flow projections, discount rates and management assumptions. Self-Insured Liabilities: The Company is self-insured for certain losses that include, but are not limited to, employee health, workers’ compensation, general liability, real and personal property, and real estate construction warranty and defect claims. When feasible, the Company obtains third-party insurance coverage to limit its exposure to these claims. When estimating its self-insured liabilities, the Company considers a number of factors, including historical claims experience, demographic factors, and valuations provided by independent third-parties. Revenue Recognition and Leases - The Company as a Lessor: 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 under lease accounting guidance with the Company as lessor. Leases - The Company as Lessor: The Company reviews its contracts to determine if they qualify as a lease. A contract is determined to be a lease when the right to substantially all of the economic benefits and to direct the use of an identified asset is transferred to a customer over a defined period of time for consideration. During this review, the Company evaluates among other items, asset specification, substitution rights, purchase options, operating rights and control over the asset during the contract period. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately under ASC 606, Revenue from Contracts with Customers . The Company has elected the practical expedient to not separate non-lease components from lease components for all classes of underlying assets where the component follows the same timing and pattern as the lease component and the lease component is classified as an operating lease. Non-lease components included in rental revenue primarily consist of tenant reimbursements for common area maintenance and other services paid for by the lessor and utilized by the lessee. Under the practical expedient, the Company accounts for the single, combined component under leasing guidance as the lease component is the predominant component in the contract. Rental revenue is primarily derived from operating leases and, therefore, is generally recognized on a straight-line basis over the term of the lease. Fixed contractual payments from the Company's leases are recognized on a straight-line basis over the terms of the respective leases. Straight-line rental revenue commences when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Certain of the Company's lease agreements include terms for contingent rental revenue (e.g. percentage rents based on tenant sales volume) and tenant reimbursed property taxes, which are both accounted for as variable payments. Certain of the Company's leases include termination and/or extension options. Termination options allow the customer to terminate the lease prior to the end of the lease term under specific circumstances. The Company's extension options generally require a re-negotiation with the customer at market rates. Initial direct costs, primarily commissions, related to the leasing of properties are capitalized on the balance sheet and amortized over the lease term. All other costs to negotiate or arrange a lease are expensed as incurred. Accounts receivable related to leases are regularly evaluated for collectability, considering factors including, but not limited to, the credit quality of the customer, historical trends of the customer, and changes in customer payment terms. Upon determination that the collectability of a customer receivable is not probable, the Company will reverse the receivable and record a corresponding reduction of revenue previously recognized. Subsequent revenue is recorded on a cash basis until collectability on related billings becomes probable. 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. Related to its long-term construction contracts, due to the nature of the work required to be performed, estimating total revenue and cost at completion of the contract is complex, subject to many variables and requires significant judgment. Such estimates of contract revenue and cost are dependent on a number of factors that may change during a contract performance period, resulting in changes to estimated contract profitability. These factors include, but are not limited to, the completeness and accuracy of the original bid; changes in the timing of scheduled work; change orders; unusual weather conditions; changes in costs of labor and/or materials; changes in productivity expectations; and the expected, or actual, resolution terms for claims. Management evaluates changes in estimates on a contract by contract basis and uses the cumulative catch-up method to account for the changes in the period in which they are determined. 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. On a consolidated basis, in addition to disclosing amounts recorded as contract assets or contract liabilities in its consolidated balance sheets, the Company discloses information about the amount of contract consideration allocated to either wholly unsatisfied or partially satisfied performance obligations (refer to Note 6, "Revenue and Contract Balances"). Related to this disclosure, the Company has elected to not disclose information about the amount of contract consideration allocated to remaining performance obligations for certain contracts that have original expected durations of one year or less. Although rare, this may occur with contracts for sales of real estate that are executed as of the end of the period with control of the underlying assets to be transferred to the customer subsequent to the end of the period. The closing date of such transactions will generally occur within one year or less of the contract execution date. Impairment of Long-Lived Assets and Finite-Lived Intangible Assets: Long-lived assets, including finite-lived intangible assets, are reviewed for possible impairment when events or circumstances indicate that the carrying value may not be recoverable. In such an evaluation, the estimated future undiscounted cash flows generated by the asset are compared with the amount recorded for the asset to determine if its carrying value is not recoverable. If this review determines that the recorded value will not be recovered, the amount recorded for the asset is reduced to estimated fair value. The measurement of fair value involves judgments and estimates including, but not limited to, the timing and amount of future cash flows, expected useful lives of the assets, comparable replacement assets, uncertainty about future events, such as changes in economic conditions, changes in operating performance, and changes in the use of the assets and ongoing costs of maintenance and improvements of the assets. If management uses different assumptions or if different conditions occur in future periods, the Company’s financial condition or its future financial results could be materially impacted. In the year ended December 31, 2019 , the Company did not recognize any impairments of long-lived assets or finite-lived intangible assets. During the fourth quarter of 2018, the Company concluded that the carrying values of certain paving and quarry assets in its Materials & Construction segment were not recoverable due primarily to persisting, competitive market pressures that have negatively affected sales and margins. As a result, the Company recorded impairment charges of $40.6 million during the fourth quarter of 2018 to reduce the carrying amounts to the estimated fair value. The Company classified these fair value measurements as Level 3. The weighted average discount rate used in the intangible valuation was 13.5% . Changes to Materials & Construction fixed assets and intangible assets for the year ended December 31, 2018 consisted of the following (in millions): Intangible Assets Materials & Construction Fixed Assets Materials & Construction Balance, January 1, 2018 $ 16.5 Balance, January 1, 2018 $ 139.5 Additions to intangible assets — Additions to fixed assets 11.1 Amortization (0.9 ) Depreciation (11.2 ) Intangible impairment (7.0 ) Fixed asset impairment (33.6 ) Balance, December 31, 2018 $ 8.6 Balance, December 31, 2018 $ 105.8 During the year ended December 31, 2017, the Company recorded aggregate impairment charges of $22.4 million related to certain of the Company's U.S. Mainland commercial properties that were classified as held for sale. The impaired assets were measured at fair value on a nonrecurring basis subsequent to their initial recognition. The Company estimated the fair values of these long-lived assets based on the Company’s own judgments about the assumptions that market participants would use in pricing the real estate assets and available, observable market data. The Company classified these fair value measurements as Level 3. Impairment of Investments in Affiliates: The Company's investments in affiliates that are accounted for under the equity method are reviewed for impairment whenever there is evidence that fair value may be below carrying cost. An investment is written down to fair value if fair value is below carrying cost and the impairment is believed to be other-than-temporary. Refer to Note 5, "Investments in Affiliates," for further discussion. Share-Based Compensation: The Company records compensation expense for all share-based payment awards made to employees and directors. The Company’s various equity plans are more fully described in Note 13, "Share-Based Payment Awards." Employee Benefit Plans: The Company provides a wide range of benefits to existing employees and retired employees, including single-employer defined benefit plans, postretirement, defined contribution plans, post-employment and health care benefits. The Company records amounts relating to these plans based on various actuarial assumptions, including discount rates, assumed rates of return, compensation increases, turnover rates and health care cost rate trends. The Company reviews its actuarial assumptions on an annual basis and makes modifications to the assumptions based on current economic conditions and trends. The Company believes that the assumptions utilized in recording obligations under the Company’s plans, which are presented in Note 11, "Employee Benefit Plans," are reasonable based on its experience and on advice from its independent actuaries; however, differences in actual experience or changes in the assumptions may materially affect the Company’s financial position or results of operations.

The revenue, operating income (loss), gain on asset dispositions, income tax benefit (expense) and after-tax effects of these transactions for the years ended December 31, 2019, 2018 and 2017 were as follows (in millions, except per share amounts): 2019 2018 2017 Sugar operations revenue $ — $ — $ 22.9 Sugar operations costs and expenses — — 22.5 Operating income (loss) from sugar operations — — 0.4 Sugar operations cessation costs (1.1 ) (0.6 ) (2.7 ) Gain (loss) on asset dispositions (0.4 ) — 6.0 Income (loss) from discontinued operations before income taxes (1.5 ) (0.6 ) 3.7 Income tax benefit (expense) — — (1.3 ) Income (loss) from discontinued operations, net of income taxes $ (1.5 ) $ (0.6 ) $ 2.4 Basic earnings (loss) per share $ (0.02 ) $ (0.01 ) $ 0.05 Diluted earnings (loss) per share $ (0.02 ) $ (0.01 ) $ 0.04 There was no depreciation and amortization related to discontinued operations for the years ended December 31, 2019, 2018 and 2017 . On December 17, 2018, A&B entered into a Purchase and Sale Agreement and Escrow Instructions (the "PSA") with Mahi Pono (the "Buyer") related to the Agricultural Land Sale, which resulted in the sale of approximately 41,000 acres of Maui agricultural land and 100% of the Company's ownership interest in Central Maui Feedstocks LLC and Kulolio Ranch LLC in exchange for cash consideration of approximately $261.6 million , less customary closing costs and fees, subject to certain contingencies and reserves of approximately $19.5 million . The Agricultural Land Sale closed on December 20, 2018, with the exception of approximately 800 acres that were delivered to the Buyer in February 2019. In connection with the Agricultural Land Sale, the Company recognized gross profit of approximately $162.2 million during the year ended December 31, 2018, and $6.7 million during the year ended December 31, 2019. The Company also deferred approximately $62.0 million of revenue related to certain performance obligations involving securing adequate water to support the Buyer's agricultural plans for the land, through an agreement with the State of Hawai‘i to provide rights to access state water for agricultural irrigation (“State Water Lease”), as well as ensuring that the Buyer has continued access to water prior to the issuance of the State Water Lease. Under the terms of the PSA, the Company may be required to remit amounts up to $62.0 million to the Buyer to the extent performance obligations are not met (recorded as deferred revenue of $62.0 million as of December 31, 2019 and 2018 ). The Agricultural Land Sale was deemed an asset sale and represents normal recurring activity for the Land Operations segment. Revenue and the cost of the land sold were presented within Operating Revenue: Land Operations and Cost of Land Operations, respectively, in the accompanying consolidated statements of operations. The disposition of the Agricultural Land Sale did not qualify to be reported as discontinued operations since the disposition did not represent a strategic shift in the Company’s operations. Accordingly, the operating results of the assets are reflected in the Company’s results from continuing operations for all periods presented through the date of disposition.

Equity Method Investments and Joint Ventures [Abstract]
Investments in Affiliates	INVESTMENTS IN AFFILIATES The Company's investments in affiliates consist principally of equity investments in limited liability companies in which the Company has the ability to exercise significant influence over the operating and financial policies of these investments. Accordingly, the Company accounts for its investments using the equity method of accounting. The Company’s investments in affiliates totaled $167.6 million and $171.4 million as of December 31, 2019 and 2018 , respectively. The amounts of the Company’s investment as of December 31, 2019 and 2018 that represent undistributed earnings of investments in affiliates were approximately $9.2 million and $7.8 million , respectively. Dividends and distributions from unconsolidated affiliates totaled $12.4 million in 2019 , $51.1 million in 2018 and $10.4 million in 2017 . Operating results include the Company's proportionate share of net income (loss) from its equity method investments. A summary of combined financial information related to the Company's equity method investments as of December 31, 2019 and 2018 were as follows (in millions): 2019 2018 Current assets $ 79.3 $ 71.1 Non-current assets 697.9 755.8 Total assets $ 777.2 $ 826.9 Current liabilities $ 27.1 $ 26.8 Non-current liabilities 109.0 149.2 Total liabilities $ 136.1 $ 176.0 A summary of the net income (loss) information related to the Company's equity method investments for each of the years ended December 31, 2019, 2018 and 2017 were as follows (in millions): 2019 2018 2017 Revenues $ 191.9 $ 243.6 $ 200.5 Operating costs and expenses 173.0 209.7 166.3 Gross profit (loss) $ 18.9 $ 33.9 $ 34.2 Income (loss) from Continuing Operations* $ 6.6 $ 17.4 $ 16.0 Net Income (loss)* $ 6.6 $ 16.5 $ 15.5 * Includes earnings from equity method investments held by the investee. The carrying value of the Company's investment in Kukui‘ula, which includes capital contributed by the Company to the joint venture and the value of land initially contributed, net of joint venture earnings and losses and impairments, was $116.2 million and $115.4 million as of December 31, 2019 and 2018 , respectively. The total capital contributed to the joint venture by the Company as a percent of total committed was approximately 62% as of December 31, 2019 . The Company does not have a controlling financial interest in the joint venture, but exercises significant influence over the operating and financial policies of the venture and, therefore, accounts for its investment using the equity method. Due to the complex nature of cash distributions to the members, net income of the joint venture is allocated to the members, including the Company, using the Hypothetical Liquidation at Book Value (“HLBV”) method. Under the HLBV method, joint venture income or loss is allocated to the members based on the period change in each member’s claim on the book value of net assets of the venture, excluding capital contributions and distributions made during the period. The Company also has investments in various other joint ventures that operate or develop real estate and joint ventures that engage in materials and construction-related activities and renewable energy. The Company does not have a controlling financial interest, but has the ability to exercise significant influence over the operating and financial policies of these joint ventures and, accordingly, accounts for its investments in these ventures using the equity method of accounting. Impairment of Investments in Affiliates: When there is evidence that the fair value of the Company's investments in affiliates that are accounted for under the equity method may be below the carrying value, the Company must determine if such decline in value is other-than-temporary. In evaluating the fair value of an investment and whether any identified impairment is other-than-temporary, significant estimates and considerable judgments are involved. These estimates and judgments are based, in part, on the Company’s current and future evaluation of economic conditions in general, as well as a joint venture’s current and future plans. Additionally, these impairment calculations are highly subjective because they require management to make assumptions and apply judgments to estimates regarding the timing and amount of future cash flows that may consider various factors, including sales prices, development costs, market conditions and absorption rates, probabilities related to various cash flow scenarios, and appropriate discount rates based on the perceived risks, among others. In evaluating whether an impairment is other-than-temporary, the Company considers all available information, including the length of time and extent of the impairment, the financial condition and near-term prospects of the affiliate, the Company’s ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value, and projected industry and economic trends, among others. Changes in these and other assumptions could affect the projected operational results and fair value of the unconsolidated affiliates, and accordingly, may require valuation adjustments to the Company’s investments that may materially impact the Company’s financial condition or its future operating results. Weakness in particular real estate markets, difficulty in obtaining or renewing project-level financing or development approvals, and changes in the Company’s development strategy, among other factors, may affect the value or feasibility of certain development projects owned by the Company or by its joint ventures and could lead to additional impairment charges in the future. In the year ended December 31, 2019 , the Company did not recognize any impairments of investments in affiliates. During the fourth quarter of 2018, the Company recorded impairments of investments in affiliates of $188.6 million . This amount was primarily driven by an impairment in its investment in Kukui‘ula. In 2018, the Company determined that its investment in Kukui‘ula was other-than-temporarily impaired as a result of changing its strategy and no longer intending to hold its investment through the duration of the project. As a result, the Company estimated the fair value of its investment in Kukui‘ula (using a discounted cash flow model) to be below its carrying value and recorded a non-cash, other-than-temporary impairment of $186.8 million . The Company classified the fair value measurement as Level 3. The weighted average discount rate used in the valuation was 18.0% .

Revenue from Contract with Customer [Abstract]
Revenue and Contract Balances	REVENUE AND CONTRACT BALANCES 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. Revenue by type for the years ended December 31, 2019 and 2018 was as follows (in millions): 2019 2018 Revenues: Commercial Real Estate $ 160.6 $ 140.3 Land Operations: Development sales revenue 57.2 54.3 Unimproved/other property sales revenue 32.4 210.5 Other operating revenue 24.5 24.7 Total Land Operations 114.1 289.5 Materials & Construction 160.5 214.6 Total revenues $ 435.2 $ 644.4 The total amount of contract consideration allocated to either wholly unsatisfied or partially satisfied performance obligations was $75.7 million and $128.7 million as of December 31, 2019 and 2018 , respectively. The Company expects to recognize approximately 70% to 80% of this contract consideration as revenue in 2020 , with the remaining recognized thereafter. Timing of revenue recognition may differ from the timing of invoicing to customers. Certain construction contracts include retainage provisions that are customary in the industry (i.e., are not for financing purposes) and are included in Contracts retention . 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 customers. Costs and estimated earnings in excess of billings on uncompleted contracts 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 on uncompleted contracts 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 as of December 31, 2019 and 2018 : (in millions) 2019 2018 Accounts receivable, net $ 43.4 $ 49.6 Contracts retention 8.6 11.6 Costs and estimated earnings in excess of billings on uncompleted contracts 10.0 9.2 Billings in excess of costs and estimated earnings on uncompleted contracts 7.9 5.9 Variable consideration (1) 62.0 62.0 Other long term deferred revenue 5.6 1.2 (1) Variable consideration recorded in connection with the Agricultural Land Sale. See Note 21. For the year ended December 31, 2019 , the Company recognized revenue of approximately $4.7 million related to the Company's contract liabilities reported as of December 31, 2018 . For the year ended December 31, 2018 , the Company recognized revenue of approximately $4.2 million related to the Company's contract liabilities reported as of December 31, 2017 . The amount of revenue recognized from performance obligations satisfied in prior periods was not material.

Secured Debt Kailua Town Center: On December 20, 2013, the Company consummated the acquisition of the Kailua Portfolio, a collection of retail assets on Oahu. In connection with the acquisition of the Kailua Portfolio, the Company assumed a $12.0 million mortgage note, which matures in September 2021 , and an interest rate swap that effectively converts the floating rate debt to a fixed rate of 5.95% (see Note 15). As of December 31, 2019 , the balance of the mortgage note was $10.2 million . The Company also secured a $5.0 million second mortgage on the Kailua Portfolio during the first quarter of 2017, which bears interest at 3.15% and matures in 2021 . The second mortgage has an outstanding balance at December 31, 2019 of $4.6 million . Heavy Equipment Financing: In connection with the M&C segment, the Company enters into leases for machinery related to its businesses that are classified as finance leases. Finance leases are further discussed in Note 9. Laulani Village: In connection with asset acquisitions of commercial real estate improved properties made in the year ended December 31, 2018, the Company assumed a $62.0 million mortgage secured by Laulani Village that matures on May 1, 2024 .

On December 1, 2014, the Company refinanced and increased the amount of the loan secured by the Property. The new loan ("Refinanced Loan") was increased to $92.0 million and bears interest at 4.15% . The Refinanced Loan matures in December 2024, and requires monthly principal and interest payments of approximately $0.4 million . A final principal payment of approximately $73.0 million is due on December 8, 2024. The Refinanced Loan is secured by the Property under a Mortgage and Security Agreement between the Company and The Northwestern Mutual Life Insurance Company. Manoa Marketplace: In 2016, ABL Manoa Marketplace LF LLC, A&B Manoa LLC, ABL Manoa Marketplace LH LLC, and ABP Manoa Marketplace LH LLC (the "Borrowers"), wholly owned subsidiaries of the Company, entered into a $60.0 million mortgage loan agreement ("Loan") with First Hawaiian Bank ("FHB"). The Loan bears interest at LIBOR plus 1.35% and matures on August 1, 2029 . The Loan requires interest-only payments for the first 36 months and principal and interest payments for the remaining 120 months using a 25 -year amortization period. A final principal payment of $41.7 million is due on August 1, 2029. The Company had previously entered into an interest rate swap with a notional amount equal to the principal amount on the debt to fix the variable interest rate on the related periodic interest payments at an effective rate of 3.14% (see Note 15). The Loan is secured by Manoa Marketplace under a Mortgage, Security Agreement and Fixture Filing between the Borrowers and FHB, dated August 1, 2016. Assets Pledged as Collateral: The approximate book values of assets used in the Commercial Real Estate segment pledged as collateral under the foregoing credit agreements at December 31, 2019 was $374.5 million .

There were no assets used in the Land Operations segment that were pledged as collateral. Unsecured Debt Term Loan 3: In connection with its M&C segment, Grace Pacific held a term loan with FHB which included interest at 5.19% .

The Term Loan 4 was interest only and included interest at LIBOR plus 2.0% . Outstanding amounts for Term Loan 4 were repaid in the year ended December 31, 2019; as of December 31, 2019 , there is no outstanding balance of the Term Loan 4. Prudential Series Notes: In December 2015, the Company entered into an agreement (the "Prudential Agreement") with Prudential Investment Management, Inc. and its affiliates (collectively, "Prudential") for an unsecured note purchase and private shelf facility that enabled the Company to issue notes in an aggregate amount up to $450.0 million , less the sum of all principal amounts then outstanding on any notes issued by the Company or any of its subsidiaries to Prudential and the amounts of any notes that are committed under the Prudential Agreement. The Prudential Agreement (which amended and renewed a then-existing agreement) had an issuance period that ended in December 2018 and contained certain restrictive covenants for the notes issued under the Prudential Agreement that were substantially the same as the covenants contained in the Historical Revolving Credit Facility (defined below). Borrowings under the uncommitted shelf facility bear interest at rates that were determined at the time of borrowing. In September 2017, the Company entered into an amendment of the Prudential Agreement (the "Pru Amendment"), which amended certain covenants (see below). Additionally, the Pru Amendment included a provision for a contingent incremental interest rate increase of 20 basis points on all outstanding notes that was based on the Company's ratio of debt to total adjusted asset value (as defined in the Pru Amendment) measured against the provision's allowed ratio 0.35 to 1.0 from the date of the amendment through September 30, 2018. If triggered, the contingent interest rate adjustment would continue until such time that the Company's ratio of debt to total adjusted asset value declined to 0.35 to 1.0 or below (at which point the provision would have no further force or effect). In October 2018, the provision was triggered and interest rates for all Prudential Series Notes increased by 20 basis points. In March 2019, based on the Company's subsequent leverage-based ratio falling below the provision's threshold. the interest rates for all Prudential Series Notes returned to their originally stated amounts at the time of the borrowing. Bank Syndicated Loan: In February 2018, the Company entered into an agreement with Wells Fargo Bank, National Association ("Wells Fargo") and a syndicate of other financial institutions that provides for a $50.0 million term loan facility ("Wells Fargo Term Facility" or "Bank Syndicated Loan"). The Company also drew $50.0 million under the Wells Fargo Term Facility in February 2018 and used such term loan proceeds to repay amounts that were borrowed under the A&B Revolver. 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. Term Loan 5: In November 2017, the Company entered into a rate lock commitment to draw $25.0 million under its Note Purchase and Private Shelf Agreement with AIG Asset Management (U.S.), LLC. Under the commitment, the Company drew $25.0 million in December 2017. The note bears interest at 4.30% and matures on December 20, 2029. Interest only is paid semi-annually and the principal balance is due at maturity. Revolving Credit Facilities GLP Asphalt Revolving Credit Facility: At December 31, 2017, the Company had, at one of its subsidiaries, GLP, a $30.0 million line of credit with a maturity date in October 2018. The credit line is collateralized by the subsidiary's accounts receivable, inventory and equipment and may only be used for asphalt purchase. The Company and the noncontrolling interest holders are guarantors, on a several basis, for their pro rata shares (based on membership interests) of borrowings under the line of credit. In September 2018, GLP entered into a Third Amended Credit Agreement with Wells Fargo, which amended and extended its existing $30.0 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 GLP Asphalt Revolving Credit Facility remain substantially unchanged. As of December 31, 2019 , there is no outstanding balance on the GLP Asphalt Revolving Credit Facility. The GLP Asphalt Revolving Credit Facility contains certain restrictive covenants. Based on its net income after taxes in the year ended December 31, 2019, GLP was not in compliance with all of the covenants and received waivers on such requirements. As noted above, as of December 31, 2019 , there is no outstanding balance on the GLP Asphalt Revolving Credit Facility. A&B Revolver: The Company had a revolving senior credit facility that provided for an aggregate $350.0 million , five -year unsecured commitment (the "Historical Revolving Credit Facility"), with an uncommitted $100.0 million increase option. The Historical Revolving Credit Facility also provided for a $100.0 million sub-limit for the issuance of standby and commercial letters of credit and an $80.0 million sub-limit for swing line loans. Amounts drawn under the facilities would bear interest at a stated rate, as defined, plus a margin that is determined based on a pricing grid using the ratio of debt to total adjusted asset value, as defined. The agreement contained certain restrictive covenants, the most significant of which requires the maintenance of minimum shareholders’ equity levels, minimum EBITDA to fixed charges ratio, maximum debt to total assets ratio, minimum unencumbered income-producing asset value to unencumbered debt ratio, and limitations on priority debt, as defined in the agreement. In December 2015, the Historical Revolving Credit Facility was amended to extend the maturity date to December 2020. In September 2017, the Company entered into a Second Amended and Restated Credit Agreement ("A&B Revolver") with Bank of America N.A., as administrative agent, First Hawaiian Bank, and other lenders party thereto, which amended and restated the existing $350.0 million commitment under the Historical Revolving Credit Facility. The A&B Revolver increased the total revolving commitments to $450.0 million , extended the term of the facilities to September 15, 2022 , amended certain covenants (see below), and reduced the interest rates and fees charged under the Historical Revolving Credit Facility. All other terms under the Historical Revolving Credit Facility remained substantially unchanged. At December 31, 2019 , the Company had $98.7 million of revolving credit borrowings outstanding, $1.7 million in letters of credit had been issued against the facility, and $349.6 million remained available. Covenants under A&B Revolver and Pru Amendment (Subsequent to Amendments) The principal amendments under the A&B Revolver and the Pru Amendment are as follows: • An increase in the maximum ratio of debt to total adjusted asset value from 0.5 : 1.0 to 0.6 : 1.0 . • An increase in the aggregate maximum amount of priority debt at any time from 20% to 25% . • Allows the Company to consummate the holding company merger to adopt certain governance changes and facilitate the Company's ongoing compliance with REIT requirements. • Sets the minimum shareholders' equity amount to be $850.6 million plus 75% of the net proceeds received from equity issuances, less non-recurring costs related to the REIT conversion, among other additions and subtractions. • Allows for the payment of minimum dividends required to maintain REIT status and other dividends in any amount so long as no event of default shall then exist or would exist after giving effect to such dividends. As a result of the special distribution that was declared on November 16, 2017 and settled on January 23, 2018 related to the Company's REIT conversion, the Company received waivers related to the impact of the Special Distribution on the minimum shareholder’s equity computation for the A&B Revolver and its unsecured term loan agreements. Debt Maturities At December 31, 2019 , debt maturities during the next five years and thereafter, excluding amortization of debt discount or premium, are $30.9 million in 2020 , $43.3 million in 2021 , $128.5 million in 2022 , $84.3 million for 2023 , $157.0 million in 2024 , and $261.2 million thereafter.

Retirement Benefits [Abstract]
Employee Benefit Plans	EMPLOYEE BENEFIT PLANS The Company has funded single-employer defined benefit pension plans that cover substantially all non-bargaining unit employees and certain bargaining unit employees. In addition, the Company has plans that provide certain retiree health care and life insurance benefits to substantially all salaried and certain hourly employees. Employees are generally eligible for such benefits upon retirement and completion of a specified number of years of credited service. The Company does not pre-fund these health care and life insurance benefits and has the right to modify or terminate certain of these plans in the future. Certain groups of retirees pay a portion of the benefit costs. Plan Administration, Investments and Asset Allocations: As the plan sponsor for its defined benefit pension plan, the Company is responsible for the investment and management of the pension plan assets. The Company manages the pension plan assets based upon a liability-driven investment strategy, which seeks to increase the correlation of the pension plan assets and liabilities to reduce the volatility of the plan's funded status and, over time, improve the funded status of the plan. As a result, the asset allocation of the defined benefit pension plan is weighted toward fixed income investments, which reduces investment volatility, but also reduces investment returns over time. In connection with the liability-driven investment strategy, the Company appointed an investment adviser that directs investments and selects investment options, based on established guidelines. The Company’s weighted-average asset allocations at December 31, 2019 and 2018 , and 2019 year-end target allocation, by asset category, were as follows: Target 2019 2018 Fixed income securities 100 % 99 % 99 % Cash and cash equivalents — % 1 % 1 % Total 100 % 100 % 100 % Fixed income debt securities include investment-grade corporate bonds from diversified industries and U.S. Treasuries. The expected return on plan assets assumption ( 4.30% for 2019 ) is principally based on the long-term outlook for various asset class returns, asset mix, the historical performance of the plan assets under the liability-driven investment strategy, and a comparison of the estimated long-term return calculated to the distribution of assumptions adopted by other plans with similar asset mixes. For the years ended December 31, 2019 and 2018 , the plan assets experienced a positive return of 18.08% and a negative return of 5.10% , respectively. The Company’s pension plan assets are held in a master trust and stated at estimated fair value, which is based on the fair values of the underlying investments. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. The fair values of the Company’s defined benefit pension plan assets at December 31, 2019 and 2018 , by asset category, are as follows (in millions): Fair Value Measurements at December 31, 2019 December 31, 2018 Total Quoted Prices in Active Markets (Level 1) Significant Observable Inputs Total Quoted Prices in Active Markets (Level 1) Significant Observable Inputs Asset Category Cash and cash equivalents $ 1.2 $ 1.2 $ — $ 1.4 $ 1.4 $ — Fixed income securities U.S. Treasury obligations — — — — — — Domestic corporate bonds and notes — — — — — — Foreign corporate bonds — — — — — — Assets measured at NAV 189.3 — — 172.2 — — Total $ 190.5 $ 1.2 $ — $ 173.6 $ 1.4 $ — Investments in funds that are measured at fair value using the NAV per share practical expedient in accordance with ASC 820 have not been classified in the fair value hierarchy tables above. The NAV is based on the fair value of the underlying assets owned by the fund and is determined by the investment manager or custodian of the fund. The fair value amounts presented are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the fair value of plan assets. These investments primarily include other fixed income investments and securities. Contributions are determined annually for each plan by the Company’s pension Administrative Committee, based upon the actuarially determined minimum required contribution under the Employee Retirement Income Security Act of 1974, as amended, the Pension Protection Act of 2006, and the maximum deductible contribution allowed for tax purposes. In 2019 and 2018 , the Company made no contributions to its defined benefit pension plans. In 2017 , the Company contributed approximately $49.2 million to its defined benefit pension plans. The Company’s funding policy is to contribute cash to its pension plans so that it meets at least the minimum contribution requirements. For the plans covering employees who are members of collective bargaining units, the benefit formulas are determined according to the collective bargaining agreements, either using career average pay as the base or a flat dollar amount per year of service. In 2007, the Company changed the traditional defined benefit pension plan formula for new non-bargaining unit employees hired after January 1, 2008 and, replaced it with a cash balance defined benefit pension plan formula. Subsequently, effective January 1, 2012, the Company changed the benefits under its traditional defined benefit plans for non-bargaining unit employees hired before January 1, 2008 and, replaced the benefit with the same cash balance defined benefit pension plan formula provided to those employees hired after January 1, 2008. Retirement benefits under the cash balance pension plan formula are based on a fixed percentage of eligible compensation, plus interest. The plan interest credit rate will vary from year-to-year based on the 10-year U.S. Treasury rate. During the year ended December 31, 2019, the Company amended the cash balance pension plan such that, effective January 1, 2020, benefit accruals under the cash balance formula would cease and would be replaced with a non-elective contribution by the Company into a defined contribution plan. All accumulated benefits under the traditional defined benefit pension plan and the cash balance pension plan will remain credited to employees' accounts under the amendments made in 2019. Benefit Plan Assets and Obligations: The measurement date for the Company’s benefit plan disclosures is December 31 of each year.

The accumulated benefit obligation for the Company’s qualified pension plans was $204.4 million and $189.6 million at December 31, 2019 and 2018 , respectively. Amounts recognized on the consolidated balance sheets in accumulated other comprehensive income (loss) at December 31, 2019 and 2018 were as follows (in millions): Pension Benefits Other Post-retirement Benefits Non-qualified Plan Benefits 2019 2018 2019 2018 2019 2018 Net loss (gain) (net of taxes) $ 47.4 $ 56.2 $ (0.2 ) $ — $ 0.8 $ 0.5 Unrecognized prior service credit (net of taxes) — (1.4 ) — — — (0.1 ) Total $ 47.4 $ 54.8 $ (0.2 ) $ — $ 0.8 $ 0.4 The information for qualified pension plans with an accumulated benefit obligation in excess of plan assets at December 31, 2019 and 2018 are shown below (in millions): 2019 2018 Projected benefit obligation $ 204.4 $ 189.6 Accumulated benefit obligation $ 204.4 $ 189.6 Fair value of plan assets $ 190.5 $ 173.6 The estimated prior service credit for the defined benefit pension plans that will be amortized from accumulated other comprehensive income (loss) into net periodic benefit cost in 2020 is negligible . The estimated net loss that will be recognized in net periodic pension cost for the defined benefit pension plans in 2020 is $2.4 million . The estimated net loss for the other defined benefit post-retirement plans that will be amortized from accumulated other comprehensive income (loss) into net periodic pension cost in 2020 is negligible . The estimated prior service cost for the other defined benefit post-retirement plans that will be amortized from accumulated other comprehensive income (loss) into net periodic pension cost in 2020 is negligible . Unrecognized gains and losses of the post-retirement benefit plans are amortized over 5 years. Although current health costs are expected to increase, the Company attempts to mitigate these increases by maintaining caps on certain of its benefit plans, using lower cost health care plan options where possible, requiring that certain groups of employees pay a portion of their benefit costs, self-insuring for certain insurance plans, encouraging wellness programs for employees, and implementing measures to mitigate future benefit cost increases.

The risks of participating in these multiemployer plans are different from single-employer plans in the following aspects: a. Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers. b. If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. c. If the Company chooses to stop participating in some of its multiemployer plans, the Company may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability. The Company's participation in these plans for the year ended December 31, 2019 , is outlined in the table below. The "EIN Pension Plan Number" column provides the Employee Identification Number (EIN) and the 3-digit plan number, if applicable. The most recent Pension Protection Act (PPA) zone status available in 2019 is for the plan's year-end as of December 31, 2018 , for the Pension Trust Fund for Operating Engineers Pension Plan and Laborer's National (Industrial) Pension Fund. The zone status available for 2019 for the Hawai‘i Laborers Trust Funds is for the plan year-end as of February 28, 2019 . GPRS and GPRM have separate contracts and different expiration dates with the Hawai‘i Laborers Trust Fund. The zone status is based on information that the Company received from the plan and is certified by the plan's actuary. Among other factors, plans that are less than 65% funded are "red zone" plans in need of reorganization; plans between 65% and 80% funded or that have an accumulated funding deficiency or are expected to have a deficiency in any of the next six years are "yellow zone" plans; plans that meet both of the "yellow zone" criteria are "orange zone" plans; and if the plan is funded more than 80% , it is a "green zone" plan. The "FIP/RP Status Pending/Implemented" column indicates plans for which a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. The last column lists the expiration dates of the collective-bargaining agreements to which the plans are subject.

Defined Contribution Plans : The Company sponsors defined contribution plans that qualify under Section 401(k) of the Code and provides matching contributions of up to 3% of eligible compensation. The Company’s matching contributions expensed under these plans totaled $0.2 million in the year ended December 31, 2019 and $0.6 million in each of the years ended December 31, 2018 and 2017 . The Company also maintains profit sharing plans and, if a minimum threshold of Company performance is achieved, provides contributions of 1% to 5% , depending upon Company performance above the minimum threshold. There were $0.3 million and $0.4 million of profit sharing contribution expenses recognized in the years ended December 31, 2019 and 2018 , and no profit sharing contribution expenses in 2017 . Grace 401(k) Plans : The Company allows for discretionary non-elective employer contributions up to the sum of 10% of each eligible employee's compensation for the 12 months in the plan year, subject to certain limitations. Management revenue sharing bonuses can be deferred to the employee's 401(k) account, but will be subject to the IRS' annual limit on employee elective deferrals. Grace recognized discretionary employer contribution and revenue sharing expense of $1.1 million , $1.8 million and $2.0 million in the years ended December 31, 2019, 2018 and 2017 , respectively.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES For taxable years prior to 2017, the Company filed a consolidated federal income tax return, which included 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 REIT, the Company will generally be allowed a deduction for dividends that it pays, and therefore, will not be subject to United States federal corporate income tax on its taxable income that is currently distributed to shareholders. The Company may be subject to certain state gross income and franchise taxes, as well as taxes on any undistributed income and federal and state corporate taxes on any income earned by its TRS. In addition, the Company could be subject to corporate income taxes related to assets held by the REIT that are sold during the 5-year period following the date of conversion, to the extent such sold assets had a built-in gain as of January 1, 2017. The Company does not intend to dispose of any REIT assets after the REIT conversion within the 5-year period, unless various tax planning strategies, including Internal Revenue Code Section 1031 like-kind exchanges or other deferred tax structures are available to mitigate the built-in gain tax liability of conversion. Distributions with respect to the Company’s common stock can be characterized for federal income tax purposes as ordinary income, capital gains, unrecaptured section 1250 gains, return of capital, or a combination thereof. Taxable distributions paid for the years ended December 31, 2019 and 2017 were classified as ordinary income. Distributions paid for the year ended December 31, 2018 included taxable ordinary income and a non-taxable return of capital. The income tax expense (benefit) on income (loss) from continuing operations for the years ended December 31, 2019, 2018 and 2017 consisted of the following (in millions): 2019 2018 2017 Current: Federal $ (1.6 ) $ (0.3 ) $ (2.6 ) State (0.4 ) — (0.5 ) Current $ (2.0 ) $ (0.3 ) $ (3.1 ) Deferred: Federal $ — $ 14.0 $ (200.7 ) State — 2.6 (14.4 ) Deferred $ — $ 16.6 $ (215.1 ) Income tax expense (benefit) $ (2.0 ) $ 16.3 $ (218.2 ) Income tax expense (benefit) for the years ended December 31, 2019 , 2018 , and 2017 differs from amounts computed by applying the statutory federal rate to income from continuing operations before income taxes for the following reasons (in millions): 2019 2018 2017 Computed federal income tax expense $ (8.2 ) $ (11.1 ) $ 3.3 State income taxes (5.1 ) (15.6 ) 0.1 Valuation allowance 8.3 84.4 6.9 REIT rate differential (7.9 ) (51.5 ) (2.2 ) Tax credits, including solar — — (0.3 ) Return-to-provision adjustments — — (1.1 ) Amended return (1.1 ) 0.6 (0.1 ) Share-based compensation — — (4.0 ) Noncontrolling interest 0.5 (0.6 ) (0.7 ) Rate change effect related to REIT conversion — — (223.0 ) Rate change effect related to Tax Cuts and Jobs Act of 2017 — — 3.0 Impairments 12.4 10.7 — Other—net (0.9 ) (0.6 ) (0.1 ) Income tax expense (benefit) $ (2.0 ) $ 16.3 $ (218.2 ) The change in the Company's effective tax rate for the year ended December 31, 2019 as compared to the year ended December 31, 2018 is primarily due to the Company establishing a valuation allowance in 2018 on its net deferred tax assets and recognizing substantial 2018 REIT income related to the Agricultural Land Sale in 2018. In addition, the Company recognized a benefit in the year ended December 31, 2019 for the interest income on federal refunds resulting from amended returns. The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities as of December 31, 2019 and 2018 were as follows (in millions): 2019 2018 Deferred tax assets: Employee benefits $ 10.4 $ 10.6 Capitalized costs 6.2 9.7 Joint ventures and other investments 49.1 55.7 Impairment and amortization 0.9 0.8 Solar investment benefits 16.7 16.7 Insurance and other reserves 3.2 2.6 Disallowed interest expense 8.4 4.4 Net operating losses 17.6 8.3 Operating lease liability 2.6 — Other 3.4 1.5 Total deferred tax assets $ 118.5 $ 110.3 Valuation allowance (99.3 ) (91.5 ) Total net deferred tax assets $ 19.2 $ 18.8 Deferred tax liabilities: Property (including tax-deferred gains on real estate transactions) $ 16.0 $ 17.0 Interest rate swap — 1.0 Operating lease asset 2.5 — Other 0.7 0.8 Total deferred tax liabilities $ 19.2 $ 18.8 Net deferred tax assets (liabilities) $ — $ — Federal tax credit carryforwards at December 31, 2019 totaled $8.8 million and will expire in 2036 . State tax credit carryforwards at December 31, 2019 totaled $6.9 million and may be carried forward indefinitely under state law. As of December 31, 2019 , the Company had federal net operating loss carryforwards of $12.6 million , $3.4 million of which expire in 2037 , with the remaining being carried forward indefinitely under federal law. As of December 31, 2019 , the Company had state net operating loss carryforwards of $5.0 million , of which $0.6 million of California net operating loss carryforwards will expire in 2030 , $1.4 million of Hawai‘i net operating loss carryforwards will expire in 2037 , and the remaining $3.0 million of Hawai‘i net operating loss carryforwards to be carried forward indefinitely . A valuation allowance must be provided if it is more likely than not that some portion or all of the deferred tax assets will not be realized, based upon consideration of all positive and negative evidence. Sources of evidence include, among other things, a history of pretax earnings or losses, expectations of future results, tax planning opportunities and appropriate tax law. Due to the recent losses the Company has generated in its TRS, the Company believes that it is more likely than not that its U.S. and state deferred tax assets will not be realized as of December 31, 2019 . Therefore, the Company recorded an increase in the valuation allowance of $7.8 million on its net U.S. and state deferred tax assets for the current period. Should the Company determine that it would be able to realize its deferred tax assets in the foreseeable future, an adjustment to the deferred tax assets may cause a material increase to income in the period such determination is made. Significant management judgment is required in determining the period in which reversal of a valuation allowance should occur. Balance at Beginning of Year Additions Reductions Balance at End of Year 2019 $ 91.5 $ 7.8 $ — $ 99.3 2018 $ 6.9 $ 84.6 $ — $ 91.5 2017 — 6.9 — 6.9 The Company’s income taxes receivable has been increased by the tax benefits from share-based compensation. The Company receives an income tax benefit for exercised stock options calculated as the difference between the fair market value of the stock issued at the time of exercise and the option exercise price, tax-effected. The Company also receives an income tax benefit for restricted stock units when they vest, measured as the fair market value of the stock issued at the time of vesting, tax effected. There were no net tax benefits from share-based transactions for 2019 or 2018 . The Company recognizes accrued interest and penalties on income taxes as a component of income tax expense. As of December 31, 2019 , the Company recognized a $1.1 million benefit for the interest income on federal refunds resulting from amended returns. The Company has not identified any material unrecognized tax positions and as such has no related interest or penalty accruals. As of December 31, 2019 , tax years 2016 and later are open to audit by the tax authorities. As of December 31, 2019 , the Company has one open tax examination for the 2016 Hawai‘i state income tax return. The Company believes that the result of this audit will not have a material adverse effect on its results of operations, financial condition or liquidity.

Share-based Payment Arrangement [Abstract]
Share-Based Payment Awards	SHARE-BASED PAYMENT AWARDS The 2012 Incentive Compensation Plan ("2012 Plan") allows for the granting of stock options, restricted stock units and common stock. During 2018 , the Company retroactively approved an increase to the shares of common stock reserved for issuance at January 1, 2018 from 4.3 million shares to 5.3 million shares. As of December 31, 2019 there were 1.5 million remaining shares available for grants. The shares of common stock authorized to be issued under the 2012 Plan may be drawn from the shares of the Company's authorized but unissued common stock or from shares of its common stock that the Company acquires, including shares purchased on the open market or private transactions. The 2012 Plan consists of four separate incentive compensation programs: (i) the discretionary grant program, (ii) the stock issuance program, (iii) the incentive bonus program and (iv) the automatic grant program for the non-employee members of the Company’s Board of Directors. Share-based compensation is generally awarded under three of the four programs, as more fully described below. Discretionary Grant Program: Under the Discretionary Grant Program, stock options may be granted with an exercise price no less than 100% of the fair market value (defined as the closing market price) of the Company’s common stock on the date of the grant. Options generally become exercisable ratably over three years and have a maximum contractual term of ten years . There were no option grants in 2019 , 2018 or 2017 , and the Company currently has no plans to issue options in the future. Stock Issuance Program: Under the Stock Issuance Program, shares of common stock or restricted stock units may be granted . Equity awards granted may be designated as time-based awards or market-based performance awards. Automatic Grant Program: At each annual shareholder meeting, non-employee directors will receive an award of restricted stock units that entitle the holder to an equivalent number of shares of common stock upon vesting. The following table summarizes the Company's stock option activity for the year ended December 31, 2019 (in thousands, except weighted-average exercise price and weighted-average contractual life): 2012 Plan Weighted- Weighted- Aggregate Outstanding, January 1, 2019 580.1 $ 12.91 Exercised (225.8) $ 11.29 Canceled (2.1) $ 13.11 Outstanding, December 31, 2019 352.2 $ 13.95 1.5 years $ 2,441 Vested or expected to vest 352.2 $ 13.95 1.5 years $ 2,441 Exercisable, December 31, 2019 352.2 $ 13.95 1.5 years $ 2,441 The following table summarizes non-vested restricted stock unit activity for the year ended December 31, 2019 (in thousands, except weighted-average grant-date fair value amounts): 2012 Plan Weighted- Outstanding, January 1, 2019 421.3 $ 25.91 Granted 264.0 $ 20.05 Vested (149.5) $ 23.72 Canceled (81.1) $ 22.24 Outstanding, December 31, 2019 454.7 $ 23.88 The time-based restricted stock units granted to employees vest ratably over a period of three years . The time-based restricted stock units granted to non-employee directors prior to 2018 vest ratably over a period of three years , and commencing in 2018, the time-based restricted stock units granted to non-employee directors vest over one year . The market-based performance share units cliff vest over three years , provided that the total shareholder return of the Company's common stock over the relevant period meets or exceeds pre-defined levels of total shareholder returns relative to indices, as defined. As of December 31, 2019, there was $5.0 million of total unrecognized compensation cost related to non-vested restricted stock units granted under the 2012 plan; that cost is expected to be recognized over a period of three years . The fair value of the Company's time-based awards is determined using the Company's stock price on the date of grant. The fair value of the Company's market-based awards is estimated using the Company's stock price on the date of grant and the probability of vesting using a Monte Carlo simulation with the following weighted-average assumptions: 2019 Grants 2018 Grants 2017 Grants Volatility of A&B common stock 23.6 % 22.7 % 24.1 % Average volatility of peer companies 24.2 % 21.6 % 25.6 % Risk-free interest rate 2.5 % 2.3 % 1.6 % The weighted-average grant date fair value of the time-based restricted units and market-based performance share units granted in 2019 , 2018 and 2017 was $20.05 , $28.76 and $42.85 , respectively. No compensation cost is recognized for actual forfeitures of time-based or market-based awards if an employee is terminated prior to rendering the requisite service period. There was no tax benefit realized upon vesting for the years ended December 31, 2019 and 2018 . Tax benefit realized upon vesting was $1.0 million for the year ended December 31, 2017 . The Company recognizes compensation cost net of actual forfeitures of time-based or market-based awards. A summary of compensation cost related to share-based payments is as follows for the years ended December 31, 2019 , 2018 and 2017 (in millions): 2019 2018 2017 Share-based expense: Time-based and market-based restricted stock units $ 5.4 $ 4.7 $ 4.4 Total share-based expense 5.4 4.7 4.4 Total recognized tax benefit — — (0.5 ) Share-based expense (net of tax) $ 5.4 $ 4.7 $ 3.9 Cash received upon option exercise $ 2.6 $ 0.4 $ 8.1 Intrinsic value of options exercised $ 2.6 $ 0.4 $ 13.2 Tax benefit realized upon option exercise $ — $ — $ 4.2 Fair value of stock vested $ 4.5 $ 4.0 $ 3.7

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 consolidated balance sheet, excluding lease commitments that are disclosed in Note 9, included the following (in millions) at December 31, 2019 : Standby letters of credit (a) $ 1.7 Bonds (b) $ 383.9 (a) Consists of standby letters of credit, issued by lenders under the Company’s revolving credit facilities, and relate primarily to the Company’s self insurance and workers' compensation plans. 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 $364.6 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. As of December 31, 2019 , the Company's estimated remaining exposure, assuming defaults on all existing contractual construction obligations, was approximately $39.4 million . 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 an unconsolidated joint ventures' borrowing from a third party lender, related to the repayment of a construction loan and performance of construction for the underlying project. At December 31, 2019 , the Company's limited guarantee on the indebtedness totaled $3.1 million . Legal Proceedings and Other Contingencies: Prior to the Agricultural Land Sale of approximately 41,000 acres of agricultural land on Maui to Mahi Pono in December 2018, the Company, through East Maui Irrigation Company, LLC ("EMI"), also owned approximately 16,000 acres of watershed lands in East Maui and also held four water licenses to approximately 30,000 acres owned by the State of Hawai‘i in East Maui. The sale to Mahi Pono includes the sale of a 50% interest in EMI (which closed February 1, 2019), and provides for the Company and Mahi Pono, through EMI, to jointly continue the existing process to secure a long-term lease from the State for delivery of irrigation water to Mahi Pono for use in Central 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 completion by the BLNR of a contested case hearing it ordered to be held 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 "Initial Lawsuit") alleging that the BLNR has been renewing the revocable permits annually rather than keeping them in holdover status. The lawsuit asked 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 was challenged by the three parties. In January 2016, the court ruled in the Initial 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 "Initial Ruling"). The Initial Ruling was appealed to the Intermediate Court of Appeals ("ICA") of the State of Hawai‘i. In May 2016, while the appeal of the Initial Ruling was pending, 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, November 2017 and November 2018 for calendar years 2017, 2018 and 2019. No extension of Act 126 was approved by the Hawai‘i State Legislature in 2019. In June 2019, the ICA vacated the Initial Ruling, effectively reversing the determination that the BLNR lacked authority to keep the revocable permits in holdover status beyond one year (the "ICA Ruling"). The ICA remanded the case back to the trial court to determine whether the holdover status of the permits was both (a) "temporary" and (b) in the best interest of the State, as required by statute. The plaintiffs filed a motion with the ICA for reconsideration of its decision, which was denied on July 5, 2019. On September 30, 2019, the plaintiffs filed a request with the Supreme Court of Hawai‘i to review and reverse the ICA Ruling. On November 25, 2019, the Supreme Court of Hawai‘i granted the plaintiffs' request to review the ICA Ruling. On October 11, 2019, the BLNR took up the renewal of all the existing water revocable permits in the state, acting under the ICA Ruling, and approved the continuation of the four East Maui water revocable permits for another one-year period through December 31, 2020. In a separate matter, on December 7, 2018, a contested case request filed by the Sierra Club contesting the BLNR's November 2018 approval of the 2019 revocable permits was denied by the BLNR. On January 7, 2019, Sierra Club filed a lawsuit in the circuit court of the first circuit in Hawai‘i against BLNR, A&B, and EMI, seeking to invalidate the 2019 extension of the revocable permits for, among other things, failure to perform an EA. The lawsuit also seeks to have the BLNR enjoin A&B/EMI from diverting more than 25 million gallons a day until a permit or lease is properly issued by the BLNR, and for the imposition of certain conditions on the revocable permits by the BLNR. The count seeking to invalidate the revocable permits based on the failure to perform an EA has been dismissed by the court, based on the ICA Ruling in the Initial Lawsuit. In connection with A&B’s obligation to continue the existing process to secure a long-term water lease from the State, A&B and EMI will defend against the remaining claims made by the Sierra Club. The Company 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 the Company's consolidated financial statements as a whole.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	DERIVATIVE INSTRUMENTS The Company is exposed to interest rate risk related to its floating rate 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 The Company has an interest rate swap agreement with a notional amount of $59.5 million as of December 31, 2019 , which is 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 December 31, 2019 , is as follows (dollars in millions): Effective Maturity Fixed Notional Amount at Fair Value at Classification on Date Date Interest Rate December 31, 2019 December 31, 2019 December 31, 2018 Balance Sheet 4/7/2016 8/1/2029 3.14% $ 59.5 $ (0.2 ) $ 3.9 Accrued and other liabilities The liability related to the interest rate swap as of December 31, 2019 is presented within Accrued and other liabilities in the consolidated balance sheet. The asset related to the interest rate swap as of December 31, 2018 was presented within Prepaid expenses and other assets . The changes in fair value of the cash flow hedge are recorded in accumulated other comprehensive income (loss) and subsequently reclassified into interest expense as interest is incurred on the related variable-rate debt. Non-designated Hedges As of December 31, 2019 , 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 Notional Amount at Fair Value at Classification on Date Date Interest Rate December 31, 2019 December 31, 2019 December 31, 2018 Balance Sheet 1/1/2014 9/1/2021 5.95% $ 10.2 $ (0.5 ) $ (0.5 ) Accrued and other liabilities The following table represents the pre-tax effect of the derivative instruments in the Company's consolidated statement of comprehensive income (loss) during the years ended December 31, 2019 and 2018 (in millions): 2019 2018 Derivatives in Designated Cash Flow Hedging Relationships: Amount of gain (loss) recognized in OCI on derivatives $ (4.0 ) $ 1.0 Impact of reclassification adjustment to interest expense included in Net Income (Loss) $ (0.1 ) $ — The Company records gains or losses related to interest rate swaps that have not been designated as cash flow hedges in Interest and other income (loss) in its consolidated statements of operations. There were no amounts recognized in 2019 and $0.4 million of gains recognized in 2018 related to changes in fair value. 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.

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.

Segment Reporting [Abstract]
Segment Results	SEGMENT RESULTS Operating segments are components of an enterprise that engage in business activities from which it may earn revenues and incur expenses, whose operating results are regularly reviewed by the chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available. The Company operates and reports on three segments: Commercial Real Estate; Land Operations; and Materials & Construction. The Commercial Real Estate segment owns, operates, and manages a portfolio of retail, office and industrial properties in Hawai‘i totaling 3.9 million square feet of gross leasable area. The Company also leases approximately 153.8 acres of commercial land in Hawai‘i to third-party lessees. The Land Operations segment generates its revenues and creates value through an active and comprehensive program of land stewardship, planning, entitlement, development, real estate investment and sale of land and commercial and residential properties, principally in Hawai‘i. The Materials & Construction segment performs asphalt paving as prime contractor and subcontractor; imports and sells liquid asphalt; mines, processes and sells rock and sand aggregates; produces and sells asphaltic concrete; provides and sells various construction- and traffic-control-related products and manufactures and sells precast concrete products. The accounting policies of the operating segments are described in Note 2, Significant Accounting Policies . Reportable segments are measured based on operating profit, exclusive of interest expense, general corporate expenses and income taxes. Revenues related to transactions between reportable segments have been eliminated in consolidation. Transactions between reportable segments are accounted for on the same basis as transactions with unrelated third parties. A significant portion of Materials & Construction revenue and accounts receivable is generated directly and indirectly from projects administered by the City and County of Honolulu and from the State of Hawai‘i. Reductions in funding of infrastructure projects by these government agencies could reduce our revenue and profits from our M&C segment. Further, although the customer mix of real estate sales in any given period in our Land Operations segment may be diverse in any given period, during the year ended December 31, 2018 , the Land Operations segment recognized $162.2 million of gross profit from the Agricultural Land Sale to Mahi Pono.

Real Estate [Abstract]
Real Estate Acquisitions	REAL ESTATE ACQUISITIONS 2019 Acquisitions During the year ended December 31, 2019 , the Company acquired five commercial real estate assets for $218.4 million that were accounted for as asset acquisitions. Such acquisitions were structured as like-kind exchanges in accordance with Internal Revenue Code §1031, using cash proceeds from the Agricultural Land Sale. The allocation of purchase price to the aggregate assets acquired and liabilities assumed in connection with the five commercial real estate acquisitions in 2019 was as follows (in millions): Fair value of assets acquired and liabilities assumed Assets acquired: Land $ 106.9 Property and improvements 91.3 In-place leases 23.2 Favorable leases 4.3 Total assets acquired $ 225.7 Liabilities assumed: Unfavorable leases $ 7.3 Total liabilities assumed 7.3 Net assets acquired $ 218.4 As of the acquisition date, the weighted-average amortization periods of the in-place and favorable leases were approximately 8.2 years and 4.7 years , respectively. The weighted-average amortization period of the unfavorable leases was approximately 18.6 years . 2018 Acquisitions During the year ended December 31, 2018 , the Company acquired five commercial real estate assets for an aggregate purchase price of $303.7 million that were accounted for as asset acquisitions. The acquisitions were largely funded through cash using §1031 proceeds from the sale of the Company's last seven mainland properties and also from the Agricultural Land Sale. The aggregate purchase price also included a mortgage loan with a contractual principal amount of $62.0 million that is secured by one of the properties and $2.7 million of capitalized and acquisition-related costs paid to third parties. The allocation of purchase price to assets acquired and liabilities assumed were as follows (in millions): Fair value of assets acquired and liabilities assumed Assets acquired: Land $ 92.8 Property and improvements 173.9 In-place leases 32.0 Favorable leases 6.7 Total assets acquired $ 305.4 Liabilities assumed: Unfavorable leases $ 2.7 Notes payable and other debt 1 $ 61.0 Total liabilities assumed 63.7 Net assets acquired $ 241.7 1 Includes a fair value adjustment of $1.0 million . As of the acquisition date, the weighted-average amortization periods of the in-place and favorable leases were approximately 12.4 years and 11.7 years , respectively. The weighted-average amortization period of the unfavorable leases was approximately 11.5 years .

Discontinued Operations and Disposal Groups [Abstract]
Agricultural Land Sale	DISCONTINUED OPERATIONS In December 2016 , the Company completed its final sugar harvest and ceased its sugar operations. The revenue, operating income (loss), gain on asset dispositions, income tax benefit (expense) and after-tax effects of these transactions for the years ended December 31, 2019, 2018 and 2017 were as follows (in millions, except per share amounts): 2019 2018 2017 Sugar operations revenue $ — $ — $ 22.9 Sugar operations costs and expenses — — 22.5 Operating income (loss) from sugar operations — — 0.4 Sugar operations cessation costs (1.1 ) (0.6 ) (2.7 ) Gain (loss) on asset dispositions (0.4 ) — 6.0 Income (loss) from discontinued operations before income taxes (1.5 ) (0.6 ) 3.7 Income tax benefit (expense) — — (1.3 ) Income (loss) from discontinued operations, net of income taxes $ (1.5 ) $ (0.6 ) $ 2.4 Basic earnings (loss) per share $ (0.02 ) $ (0.01 ) $ 0.05 Diluted earnings (loss) per share $ (0.02 ) $ (0.01 ) $ 0.04 There was no depreciation and amortization related to discontinued operations for the years ended December 31, 2019, 2018 and 2017 . On December 17, 2018, A&B entered into a Purchase and Sale Agreement and Escrow Instructions (the "PSA") with Mahi Pono (the "Buyer") related to the Agricultural Land Sale, which resulted in the sale of approximately 41,000 acres of Maui agricultural land and 100% of the Company's ownership interest in Central Maui Feedstocks LLC and Kulolio Ranch LLC in exchange for cash consideration of approximately $261.6 million , less customary closing costs and fees, subject to certain contingencies and reserves of approximately $19.5 million . The Agricultural Land Sale closed on December 20, 2018, with the exception of approximately 800 acres that were delivered to the Buyer in February 2019. In connection with the Agricultural Land Sale, the Company recognized gross profit of approximately $162.2 million during the year ended December 31, 2018, and $6.7 million during the year ended December 31, 2019. The Company also deferred approximately $62.0 million of revenue related to certain performance obligations involving securing adequate water to support the Buyer's agricultural plans for the land, through an agreement with the State of Hawai‘i to provide rights to access state water for agricultural irrigation (“State Water Lease”), as well as ensuring that the Buyer has continued access to water prior to the issuance of the State Water Lease. Under the terms of the PSA, the Company may be required to remit amounts up to $62.0 million to the Buyer to the extent performance obligations are not met (recorded as deferred revenue of $62.0 million as of December 31, 2019 and 2018 ). The Agricultural Land Sale was deemed an asset sale and represents normal recurring activity for the Land Operations segment. Revenue and the cost of the land sold were presented within Operating Revenue: Land Operations and Cost of Land Operations, respectively, in the accompanying consolidated statements of operations. The disposition of the Agricultural Land Sale did not qualify to be reported as discontinued operations since the disposition did not represent a strategic shift in the Company’s operations. Accordingly, the operating results of the assets are reflected in the Company’s results from continuing operations for all periods presented through the date of disposition. In addition to the Agricultural Land Sale, in February 2019, the Company sold 50% of its interest in East Maui Irrigation Company, LLC ("EMI") to the Buyer in exchange for cash proceeds of $2.7 million

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	GOODWILL The Company's goodwill balance as of December 31, 2019 and 2018 was $15.4 million and $65.1 million , respectively, and is attributable to the three reporting units in the M&C segment - GPC (primarily consisting of the Grace Pacific’s quarry, paving, and liquid asphalt operations), GPRS (primarily consisting of Grace Pacific’s roadway and maintenance solutions operations) and GPRM (primarily consisting of Grace Pacific’s prestressed and precast concrete operations) - and the CRE reporting unit, which is also a reportable segment. The changes in the carrying amount of goodwill (for each period a consolidated balance sheet is presented) allocated to the Company's reportable segments starting with the year ended December 31, 2018 and continuing to the year ended December 31, 2019 were as follows (in millions): 2018 2019 Materials & Construction Commercial Real Estate Total Materials & Construction Commercial Real Estate Total Balance, beginning of year Gross amount of goodwill $ 93.6 $ 8.7 $ 102.3 $ 93.6 $ 8.7 $ 102.3 Accumulated impairment losses — — — (37.2 ) — (37.2 ) 93.6 8.7 102.3 56.4 8.7 65.1 Impairment losses (37.2 ) — (37.2 ) (49.7 ) — (49.7 ) Balance, end of year Gross amount of goodwill 93.6 8.7 102.3 93.6 8.7 102.3 Accumulated impairment losses (37.2 ) — (37.2 ) (86.9 ) — (86.9 ) $ 56.4 $ 8.7 $ 65.1 $ 6.7 $ 8.7 $ 15.4 There is no goodwill related to the Land Operations segment. Goodwill impairment: The goodwill impairment test estimates the fair value of a reporting unit using various methodologies, including an income approach that is based on a discounted cash flow analysis and a market approach that involves the application of market-derived multiples. Valuations performed in conjunction with the Company's goodwill impairment tests for each reporting unit assumes that each is an unrelated business to be sold separately and independently from the other reporting units. The discounted cash flow approach relies on a number of assumptions, including future macroeconomic conditions, market factors specific to the reporting unit, the amount and timing of estimated future cash flows to be generated by the business over an extended period of time and a discount rate that considers the risks related to the amount and timing of the cash flows, among others. Under the market multiple methodology, the estimate of fair value is based on market multiples of EBITDA (earnings before interest, taxes, depreciation and amortization) or revenues. When using market multiples of EBITDA or revenues, the Company must make judgments about the comparability of those multiples in closed and proposed transactions and comparability of multiples for similar companies. If the results of the Company's test indicates that a reporting unit's estimated fair value is less than its carrying value, an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to that reporting unit. Based on the results of the valuation performed in conjunction with the Company's annual goodwill impairment test in 2018 , the carrying amounts of the GPC and GPRS reporting units exceeded their estimated fair values and goodwill was determined to be impaired. The decline in fair value was due primarily to persisting, competitive market pressures that negatively affected sales and margins. As a result, the Company recorded a non-cash impairment charge of $37.2 million during the fourth quarter of 2018. During the quarter ended September 30, 2019, the Company was required to perform an interim impairment test for the goodwill in each of its three M&C reporting units due to the continued decline in M&C sales and margins in 2019, which resulted from continued, adverse market conditions. Based on the results of the valuation performed in conjunction with this test, the carrying amounts of the three M&C reporting units exceeded their estimated fair values and goodwill was determined to be impaired. As a result, the Company recorded a non-cash impairment charge of $49.7 million during the third quarter of 2019. The Company's goodwill and impairment test estimated the fair value of the M&C reporting units using various methodologies, including a market approach that involves the application of market-derived multiples and an income approach that was based on a discounted cash flow analysis. The Company classified these fair value measurements as Level 3. The weighted-average discount rate used in the 2018 valuation and 2019 valuation was 13.6% and 12.7% , respectively.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation: The Company presents its financial statements in accordance with accounting principles generally accepted in the United States ("GAAP") as outlined in the Financial Accounting Standard Board ("FASB") Accounting Standards Codification (the "Codification" or "ASC"). The Codification is the single source of authoritative accounting principles applied by nongovernmental entities in the preparation of financial statements in conformity with GAAP.
Use of Estimates	Use of Estimates: The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Estimates and assumptions are used for, but not limited to: (i) asset impairments, including intangible assets and goodwill, (ii) litigation and contingencies, (iii) revenue recognition for long-term real estate developments and construction contracts, (iv) pension and postretirement estimates, and (v) income taxes. Future results could be materially affected if actual results differ from these estimates and assumptions.
Customer Concentration	Customer Concentration: A significant portion of Materials & Construction revenue and accounts receivable is generated directly and indirectly from projects administered by the City and County of Honolulu and from the State of Hawai‘i. Reductions in funding of infrastructure projects by these government agencies could reduce our revenue and profits from our M&C segment. Further, although the customer mix of real estate sales in any given period in our Land Operations segment may be diverse in any given period, during the year ended December 31, 2018 , the Land Operations segment recognized $162.2 million of gross profit in connection with the sale of approximately 41,000 acres of Maui agricultural land and 100% of the Company's ownership interest in Central Maui Feedstocks LLC and Kulolio Ranch LLC (collectively referred to as the "Agricultural Land Sale") in December 2018.
Reclassification	Reclassifications: During the first quarter of 2019, the Company changed the presentation of its balance sheet to be unclassified in order to be comparable with other REIT peers. The change was applied to all periods presented retrospectively. Previously reported captions for Total assets , Total liabilities and captions within Equity were not impacted.
Real estate property, net and Other property, net	Other property, net: Other property, net represents all other long-lived physical assets other than those presented in Real estate property, net and Real estate developments. The balance primarily consists of long-lived assets in the M&C segment, but also contains corporate long-lived physical assets and Land Operations long-lived physical assets that are used in other Land Operations activities and are not presented in Real estate property, net or Real estate developments above. Other property, net is stated at cost, net of accumulated depreciation. Expenditures for major renewals and betterments are capitalized. Replacements, maintenance and repairs that do not improve or extend asset lives are charged to expense as incurred. Real estate property, net: Real estate property, net primarily represents long-lived physical assets associated with the CRE segment's leasing activity (e.g., improved property leases and ground leases); it also includes landholdings and related assets in the Land Operations segment that the Company holds for either possible future development or future monetization as part of its simplification strategy. The balance primarily consists of land, buildings and improvements and is recorded at cost, net of accumulated depreciation. Expenditures for additions, improvements and other enhancements to real estate properties are capitalized, and minor replacements, maintenance and repairs that do not improve or extend asset lives are charged to expense as incurred. When assets related to real estate properties are retired or otherwise disposed of, the related cost and accumulated depreciation is removed from the accounts and any resulting gain or loss is included in results of operations for the respective period. Certain costs are capitalized related to the development and redevelopment of real estate properties, including pre-construction costs; real estate taxes; insurance; construction costs; and salaries and related costs of personnel directly involved. Additionally, the Company makes estimates as to the probability of certain development and redevelopment projects being completed. If the Company determines the development or redevelopment is no longer probable of completion, the Company expenses all capitalized costs which are not recoverable.
Acquisitions of real estate properties	Acquisitions of real estate properties: Acquisitions of real estate properties are evaluated to determine if they should be accounted for as asset acquisitions or business combinations. Under current guidance, acquisitions of real estate properties are generally considered asset acquisitions. Under asset acquisition accounting, the Company estimates the fair value of acquired tangible assets (consisting of land, buildings and tenant improvements), identifiable intangible assets and liabilities (consisting of above- and below- market leases and in-place leases), and assumed debt based on an evaluation of available information at the date of the acquisition. Based on these estimates, the purchase consideration is allocated to the acquired assets and assumed liabilities. Transaction costs incurred during the acquisition process are capitalized as a component of the purchase consideration. In estimating the fair value of the tangible and intangible assets acquired, the Company considers information obtained about each property as a result of its due diligence and marketing and leasing activities and uses various valuation methods, such as estimated cash flow projections using appropriate discount and capitalization rates, analysis of recent comparable sales transactions, estimates of replacement costs net of depreciation and other available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. Above-market and below-market lease values are estimated based on the present value (using a discount rate reflecting the risks associated with leases acquired) of the difference between: (i) the contractual amounts to be paid pursuant to the leases negotiated and in-place at the time of acquisition and (ii) management’s estimate of fair market lease rates for the property or an equivalent property, measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the estimated term of any below-market, fixed-rate renewal options for below-market leases. The capitalized above- and below-market lease values are amortized to base rental revenue over the related lease term plus fixed-rate renewal options, as appropriate. The purchase price is further allocated to in-place lease values and tenant relationship values based on management's evaluation of the specific characteristics of the acquired lease portfolio and the Company's overall relationship with the anchor tenants. Such amounts are amortized to expense over the remaining initial lease term (and expected renewal periods for tenant relationships).
Real estate developments	Real estate developments: Real estate developments represent certain costs capitalized and presented in the Land Operations segment that relate to (i) active real estate development projects intended for sale or (ii) potential future real estate development projects intended for lease that would be part of future CRE segment operations. For potential future real estate development projects intended for lease, when management with the relevant authority has approved expenditures for activities clearly associated with the development and construction of a CRE segment project (generally after all required government agency approvals have been obtained), the capitalized costs associated with such project (i.e., historical cost of land) will be presented as Real estate property, net . Certain costs capitalized relating to active real estate development projects intended for sale may include pre-construction costs (e.g., costs related to land acquisition); construction costs (e.g., grading, roads, water and sewage systems, landscaping and project amenities); direct overhead costs (e.g., utilities, maintenance, insurance and real estate taxes); capitalized interest; and salaries and related costs of personnel directly involved. For development projects, capitalized costs are allocated using the direct method for expenditures that are specifically associated with the unit being sold and the relative-sales-value method for expenditures that benefit the entire project. Direct overhead costs incurred after the development project is substantially complete and ready to be marketed are charged to selling, general and administrative expense as incurred. All indirect overhead costs are charged to selling, general and administrative costs as incurred. Cash flows related to active real estate development projects intended for sale are classified as operating activities.
Capitalized Interest	Capitalized Interest: 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 when the asset is substantially complete and ready for its intended use or
Depreciation	Depreciation:
Intangible Assets	Intangible Assets: Real estate intangible assets are recorded on the consolidated balance sheets as Real estate intangible assets, net Other intangible assets are included in Prepaid expenses and other assets
Cash and Cash Equivalents	Cash and Cash Equivalents: Cash equivalents consist of highly liquid investments with a maturity of three months or less at the date of purchase. The Company carries these investments at cost, which approximates fair value.
Restricted Cash	Restricted Cash: The Company's restricted cash balance at December 31, 2018 of $223.5 million
Allowance for Doubtful Accounts	Notes receivable : The Company's notes receivable are recorded at cost within Other receivables on the consolidated balance sheets. Generally, a loans allowance is established when the Company determines that it will be unable to collect any remaining amounts due under the agreement. Allowance for Doubtful Accounts:
Inventories	Inventories:
Leases - The Company as Lessee	Leases - The Company as Lessee: The Company determines if an arrangement is a lease at inception by considering whether that arrangement conveys the right to use an identified asset for a period of time in exchange for consideration. Operating leases are included in Operating lease right-of-use assets ("ROU assets") and Operating lease liabilities in the Company's consolidated balance sheets. ROU assets and lease liabilities related to finance leases are included in Other property, net and Notes payable and other debt , respectively, in the Company's consolidated balance sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company's leases do not provide an implicit rate and are not readily determinable, the Company uses its incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. ROU assets also include any lease payments made at or before the commencement date and excludes any lease incentives received. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense for lease payments is recognized on a straight-line basis over the lease term. In connection with its application of the lease guidance, the Company has evaluated the lease and non-lease components within its leases where it is the lessee and has elected, for all classes of underling assets, the practical expedient to present lease and non-lease components in its lease agreements as one component. The Company has also elected, for all classes of underlying assets, to not recognize lease liabilities and lease assets for leases with a term of 12 months or less.
Goodwill	Goodwill: The Company reviews goodwill for impairment at the reporting unit level annually or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount.
Fair Value Measurements	Fair Value Measurements: ASC Topic 820, Fair Value Measurements and Disclosures ("ASC 820") , as amended, establishes a fair value hierarchy, which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The hierarchy places the highest priority on unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurements) and assigns the lowest priority to unobservable inputs (Level 3 measurements). The three levels of inputs within the hierarchy are defined as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. If the technique used to measure fair value includes inputs from multiple levels of the fair value hierarchy, the lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy. The Company records its interest rate swaps at fair value. The fair values of the Company's interest rate swaps (Level 2 measurements) 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. See Note 15, "Derivative Instruments," for fair value information regarding the Company's derivative instruments. The fair value of the Company's cash and cash equivalents, accounts receivable, net and short-term borrowings approximate their carrying values due to the short-term nature of the instruments.
Self-Insured Liabilities	Self-Insured Liabilities:
Revenue Recognition	Revenue Recognition and Leases - The Company as a Lessor: 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 under lease accounting guidance with the Company as lessor.
Leases - The Company as Lessor	Leases - The Company as Lessor: The Company reviews its contracts to determine if they qualify as a lease. A contract is determined to be a lease when the right to substantially all of the economic benefits and to direct the use of an identified asset is transferred to a customer over a defined period of time for consideration. During this review, the Company evaluates among other items, asset specification, substitution rights, purchase options, operating rights and control over the asset during the contract period. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately under ASC 606, Revenue from Contracts with Customers . The Company has elected the practical expedient to not separate non-lease components from lease components for all classes of underlying assets where the component follows the same timing and pattern as the lease component and the lease component is classified as an operating lease. Non-lease components included in rental revenue primarily consist of tenant reimbursements for common area maintenance and other services paid for by the lessor and utilized by the lessee. Under the practical expedient, the Company accounts for the single, combined component under leasing guidance as the lease component is the predominant component in the contract. Rental revenue is primarily derived from operating leases and, therefore, is generally recognized on a straight-line basis over the term of the lease. Fixed contractual payments from the Company's leases are recognized on a straight-line basis over the terms of the respective leases. Straight-line rental revenue commences when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Certain of the Company's lease agreements include terms for contingent rental revenue (e.g. percentage rents based on tenant sales volume) and tenant reimbursed property taxes, which are both accounted for as variable payments. Certain of the Company's leases include termination and/or extension options. Termination options allow the customer to terminate the lease prior to the end of the lease term under specific circumstances. The Company's extension options generally require a re-negotiation with the customer at market rates. Initial direct costs, primarily commissions, related to the leasing of properties are capitalized on the balance sheet and amortized over the lease term. All other costs to negotiate or arrange a lease are expensed as incurred. Accounts receivable related to leases are regularly evaluated for collectability, considering factors including, but not limited to, the credit quality of the customer, historical trends of the customer, and changes in customer payment terms. Upon determination that the collectability of a customer receivable is not probable, the Company will reverse the receivable and record a corresponding reduction of revenue previously recognized. Subsequent revenue is recorded on a cash basis until collectability on related billings becomes probable.
Land Operations, Materials and Construction	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. Related to its long-term construction contracts, due to the nature of the work required to be performed, estimating total revenue and cost at completion of the contract is complex, subject to many variables and requires significant judgment. Such estimates of contract revenue and cost are dependent on a number of factors that may change during a contract performance period, resulting in changes to estimated contract profitability. These factors include, but are not limited to, the completeness and accuracy of the original bid; changes in the timing of scheduled work; change orders; unusual weather conditions; changes in costs of labor and/or materials; changes in productivity expectations; and the expected, or actual, resolution terms for claims. Management evaluates changes in estimates on a contract by contract basis and uses the cumulative catch-up method to account for the changes in the period in which they are determined. 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. On a consolidated basis, in addition to disclosing amounts recorded as contract assets or contract liabilities in its consolidated balance sheets, the Company discloses information about the amount of contract consideration allocated to either wholly unsatisfied or partially satisfied performance obligations (refer to Note 6, "Revenue and Contract Balances"). Related to this disclosure, the Company has elected to not disclose information about the amount of contract consideration allocated to remaining performance obligations for certain contracts that have original expected durations of one year or less. Although rare, this may occur with contracts for sales of real estate that are executed as of the end of the period with control of the underlying assets to be transferred to the customer subsequent to the end of the period. The closing date of such transactions will generally occur within one year or less of the contract execution date.
Impairment of Long-Lived Assets and Finite-Lived Intangible Assets	Impairment of Long-Lived Assets and Finite-Lived Intangible Assets:
Impairment of Investments in Affiliates	Impairment of Investments in Affiliates:
Share-Based Compensation	Share-Based Compensation:
Employee Benefit Plans	Employee Benefit Plans: The Company provides a wide range of benefits to existing employees and retired employees, including single-employer defined benefit plans, postretirement, defined contribution plans, post-employment and health care benefits. The Company records amounts relating to these plans based on various actuarial assumptions, including discount rates, assumed rates of return, compensation increases, turnover rates and health care cost rate trends. The Company reviews its actuarial assumptions on an annual basis and makes modifications to the assumptions based on current economic conditions and trends. The Company believes that the assumptions utilized in recording obligations under the Company’s plans, which are presented in Note 11, "Employee Benefit Plans," are reasonable based on its experience and on advice from its independent actuaries; however, differences in actual experience or changes in the assumptions may materially affect the Company’s financial position or results of operations.
Income Taxes	Income Taxes: The Company makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments are applied in the calculation of tax credits, tax benefits and deductions, and in the calculation of certain deferred tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. Deferred tax assets and deferred tax liabilities are adjusted to the extent necessary to reflect tax rates expected to be in effect when the temporary differences reverse. Adjustments may be required to deferred tax assets and deferred tax liabilities due to changes in tax laws and audit adjustments by tax authorities. To the extent adjustments are required in any given period, the adjustments would be included within the tax provision in the accompanying consolidated statements of operations.
Discontinued Operations	Discontinued Operations: In December 2016, the Company completed its final sugar harvest and ceased its sugar operations. Costs related to the cessation of sugar operations are presented as discontinued operations in the consolidated statements of operations. Liabilities related to the cessation of sugar operations are presented within Accrued and other liabilities
Earnings Per Share (''EPS'')	Earnings Per Share (“EPS”): Basic and diluted earnings per share are computed and disclosed in accordance with ASC Topic 260, Earnings Per Share . The Company utilizes the two-class method to compute earnings available to common shareholders. Under the two-class method, earnings are adjusted by accretion amounts to redeemable noncontrolling interests recorded at redemption value. The adjustments represent in-substance dividend distributions to the noncontrolling interest holder as the holder has a contractual right to receive a specified amount upon redemption. As a result, earnings are adjusted to reflect this in-substance distribution that is different from other common shareholders. In addition, the Company allocates net earnings to each class of common stock and participating security as if all of the net earnings for the period had been distributed. The Company's participating securities consist of time-based restricted unit awards that contain a non-forfeitable right to receive dividends and, therefore, are considered to participate in earnings with common shareholders. 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 allocable 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.
Comprehensive Income (Loss)	Comprehensive Income (Loss):
Redeemable Non-controlling Interest	Redeemable Non-controlling Interest: Non-controlling interests in subsidiaries that are redeemable for cash or other assets outside of the Company’s control at other than fair value are classified as mezzanine equity, outside of equity and liabilities. Such amounts are adjusted at each reporting date to the higher of (1) the amount resulting from the initial carrying amount, increased or decreased for cumulative amounts of the non-controlling interest's share of net income or loss, share of other comprehensive income or loss and dividends and (2) the redemption value on each annual balance sheet date. The resulting changes in the carrying value, increases or decreases, are recorded with corresponding adjustments against earnings surplus or, in the absence of earnings surplus, common stock.
Recently adopted and issued accounting pronouncements	Recently adopted accounting pronouncements In February 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 and should be implemented using a modified retrospective approach, with the option to apply the guidance at the effective date or the beginning of the earliest comparative period. The Company adopted the guidance on January 1, 2019 and elected to use the effective date as the date of initial application. Consequently, financial information was not updated and the disclosures required under the new standard are not provided for dates and periods before January 1, 2019. Additionally, the Company elected the "package of practical expedients," which permits the Company to not reassess prior conclusions about lease identification, lease classification and initial direct costs. The new guidance did not have a material impact on the accounting treatment of the Company's triple-net tenant leases, which are the primary source of our CRE revenues. However, starting in the current year, there were certain changes to the guidance under ASC 842, which will have an impact on future operating results, including initial direct costs associated with the execution of lease agreements, such as legal fees and certain transaction costs, will no longer be capitalizable and instead are expensed in the period incurred. The Company recorded ROU assets and corresponding lease liabilities of approximately $31.0 million on the consolidated balance sheet for certain leases in which it is the lessee. The adoption of ASC 842 had no impact on the Company's lease expense. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted the guidance on January 1, 2019. 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 requires the earnings effect of the hedging instrument to be presented in the same income statement line as the hedged item. The adoption of this standard did not have an impact on the Company's financial position or results of operations. In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting . The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted the guidance on January 1, 2019. 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. The adoption of this standard did not have an impact on the Company's financial position or results of operations. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) , which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The Company has evaluated the impact of the new standard to its financial statements and has elected to early adopt for the year ended December 31, 2019. Based on the Company's evaluation, there were no material impacts upon adoption. Recently issued accounting pronouncements In June 2016, the FASB issued ASU 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. This ASU was further updated by ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses , ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses , ASU No. 2019-05, Targeted Transition Relief and ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments - Credit Losses . ASU 2016-13 and related updates amend prior guidance on the impairment of financial instruments and add an impairment model that is based on expected losses rather than incurred losses with the recognition of an allowance based on an estimate of expected credit losses. ASU 2018-19 clarified that operating lease receivables are not within the scope of ASC 326 and are to remain governed by ASC 842. The provisions of ASU 2016-13, as amended in subsequently issued amendments, is effective as of January 1, 2020. The Company does not expect the adoption of this standard to have a significant impact on its financial position or results of operations. 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 in 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 as well as 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. In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract . The guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The amendments also require the entity (customer) to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. This ASU is effective for fiscal years beginning after December 15, 2019 and the amendments (which can be applied either retrospectively or prospectively under the ASU) will be applied prospectively to all implementation costs incurred after the date of adoption. The Company does not expect the adoption of this standard to have a significant impact on its financial position or results of operations.
