DESCRIPTION OF THE BUSINESS
DESCRIPTION OF THE BUSINESS	1. Matson, Inc., a holding company incorporated in January 2012 in the State of Hawaii, and its subsidiaries (“Matson” or the “Company”), is a leading provider of ocean transportation and logistics services. The Company consists of two segments, Ocean Transportation and Logistics. For financial information on the Company’s reportable segments for the three years ended December 31, 2018, see Note 3. Ocean Transportation: Matson’s Ocean Transportation business is conducted through Matson Navigation Company, Inc. (“MatNav”), a wholly-owned subsidiary of Matson, Inc. Founded in 1882, MatNav provides a vital lifeline of ocean freight transportation services to the domestic non-contiguous economies of Hawaii, Alaska and Guam, and to other island economies in Micronesia. MatNav also operates a premium, expedited service from China to Long Beach, California, and provides services to Okinawa, Japan and various islands in the South Pacific. In addition, subsidiaries of MatNav provide container stevedoring, refrigerated cargo services, inland transportation and other terminal services for MatNav and other ocean carriers on the Hawaiian islands of Oahu, Hawaii, Maui and Kauai, and in the Alaska locations of Anchorage, Kodiak and Dutch Harbor. Matson has a 35 percent ownership interest in SSA Terminals, LLC (“SSAT”), a joint venture between Matson Ventures, Inc., a wholly-owned subsidiary of MatNav, and SSA Ventures, Inc. (“SSA”), a subsidiary of Carrix, Inc. (“Terminal Joint Venture”). SSAT provides terminal and stevedoring services to various carriers at seven terminal facilities on the U.S. West Coast, including four facilities which are used by MatNav. Matson records its share of income from the Terminal Joint Venture in costs and expenses in the Consolidated Statements of Income and Comprehensive Income, and within the Ocean Transportation segment due to the nature of SSAT’s operations. Logistics: Matson’s Logistics business is conducted through Matson Logistics, Inc. (“Matson Logistics”), a wholly-owned subsidiary of MatNav. Established in 1987, Matson Logistics is an asset-light business that provides a variety of logistics services to its customers including: (i) multimodal transportation brokerage of domestic and international rail intermodal services, long-haul and regional highway trucking services, specialized hauling, flat-bed and project services, less-than-truckload services, and expedited freight services (collectively “Transportation Brokerage” services); (ii) less-than-container load consolidation (“LCL”) and freight forwarding services (collectively “Freight Forwarding” services); (iii) warehousing and distribution services; and (iv) supply chain management, non-vessel operating common carrier (“NVOCC”) freight forwarding and other services. Recent Acquisition: On August 4, 2016, Matson Logistics completed its acquisition of Span Intermediate, LLC (“Span Alaska”), a market leading provider of LCL consolidation and freight forwarding services to Alaska (the “Span Alaska Acquisition”) (see Note 18).

SIGNIFICANT ACCOUNTING POLICIES
SIGNIFICANT ACCOUNTING POLICIES	2. Principles of Consolidation: The Consolidated Financial Statements include the accounts of Matson, Inc. and all wholly-owned subsidiaries, after elimination of intercompany amounts and transactions. Significant investments in businesses, partnerships, and limited liability companies in which the Company does not have a controlling financial interest, but has the ability to exercise significant influence, are accounted for under the equity method. A controlling financial interest is one in which the Company has a majority voting interest or one in which the Company is the primary beneficiary of a variable interest entity. The Company accounts for its investment in the Terminal Joint Venture using the equity method of accounting (see Note 4). The Consolidated Financial Statements include the accounts and activities of Span Alaska from acquisition date on August 4, 2016 (see Note 18). Fiscal Year: The period end for Matson, Inc. is December 31. The period end for MatNav occurred on the last Friday in December, except for Matson Logistics Warehousing, Inc. whose period closed on December 31. Included in these Consolidated Financial Statements are 52 weeks in the 2018 and 2017 fiscal years, and 53 weeks in the 2016 fiscal year, for MatNav. Foreign Currency Transactions: The United States (U.S.) dollar is the functional currency for substantially all of the financial statements of the Company’s foreign subsidiaries. Foreign currency denominated assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars at exchange rates existing at the respective balance sheet dates. Translation adjustments resulting from fluctuations in exchange rates are recorded as a component of accumulated other comprehensive loss (gain) within shareholders’ equity. The Company translates the result of operations of its foreign subsidiaries at the average exchange rate during the respective periods. Gains and losses resulting from foreign currency transactions are included in selling, general and administrative costs in the Consolidated Statements of Income and Comprehensive Income. Use of Estimates: The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the amounts reported. Estimates and assumptions are used for, but not limited to: impairment of investments; impairment of long-lived assets, intangible assets and goodwill; capitalized interest; allowance for doubtful accounts; legal contingencies; uninsured risks and related liabilities; accrual estimates; pension and post-retirement estimates; multi-employer withdrawal liabilities; and income taxes. Future results could be materially affected if actual results differ from these estimates and assumptions. Immaterial Correction of an Error in Previously Issued Financial Statements: Subsequent to the filing of the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, the Company determined that it had incurred a partial withdrawal liability related to the Office & Professional Employees International Union (“OPEIU”), Local 153 Pension Fund (the “Local 153 Fund”). The partial withdrawal liability resulted from a decline in the number of contribution base units related to the Local 153 Fund caused by Horizon Lines, Inc. (“Horizon”) terminating all of its operations in Puerto Rico during the first quarter of 2015, prior to the Company acquiring Horizon on May 29, 2015. Accordingly, the Company corrected this error by recording an increase in other long-term liabilities of $6.7 million, a reduction in deferred income taxes of $2.6 million, and a corresponding net adjustment to goodwill of $4.1 million for the years ended December 31, 2015, 2016 and 2017. For the year ended December 31, 2017, the $2.6 million deferred income taxes adjustment was reduced by $1.0 million to reflect the remeasurement tax effects resulting from the Tax Cut and Jobs Act of 2017 (the “Tax Act”). This had the corresponding effect of increasing income taxes and decreasing net income by $1.0 million during the year ended December 31, 2107. There was no impact to net income for any other years presented. The misstatement had no net impact on the Company’s Consolidated Statements of Cash Flows. The Company believes the correction of this error is immaterial to previously issued Consolidated Financial Statements for all prior periods. Cash, Cash Equivalents and Restricted Cash: Cash equivalents consist of highly-liquid investments with original maturities of three months or less. The Company carries these investments at cost, which approximates fair value. Outstanding checks in excess of funds on deposit totaled $16.4 million and $18.7 million at December 31, 2018 and 2017, respectively, and are included in current liabilities in the Consolidated Balance Sheets. Restricted cash relates to amounts that are subject to contractual restrictions and are not readily available. Restricted cash was $4.9 million at December 31, 2018, and is included in prepaid expenses and other assets in the Consolidated Balance Sheet. There were no restricted cash amounts at December 31, 2017. Accounts Receivable, net: Accounts receivable represents amounts due from trade customers arising in the normal course of business. Accounts receivable are shown net of allowance for doubtful accounts receivable in the Consolidated Balance Sheets. At December 31, 2018, and 2017, the Company had assigned $1.0 million and $134.8 million of eligible accounts receivable, respectively, to the Capital Construction Fund (see Note 7). Allowance for Doubtful Accounts : Allowance for doubtful accounts receivable is established by management based on estimates of collectability. Estimates of collectability are principally based on an evaluation of the current financial condition of the customer and the potential risks to collection, the customer’s payment history and other factors which are regularly monitored by the Company. Changes in the allowance for doubtful accounts receivable for the three years ended December 31, 2018, 2017 and 2016 were as follows: Balance at Expense Write-offs Balance at Year (in millions) Beginning of Year (Recovery) (1) and Other End of Year 2018 $ 4.6 $ 0.8 $ (0.6) $ 4.8 2017 $ 4.2 $ 1.0 $ (0.6) $ 4.6 2016 $ 6.6 $ (0.3) $ (2.1) $ 4.2 (1) Expense is shown net of amounts recovered from previously reserved doubtful accounts. Prepaid Expenses and Other Assets: Prepaid expenses and other assets consist of the following at December 31, 2018 and 2017: As of December 31, Prepaid Expenses and Other Assets (in millions) 2018 2017 Income tax receivables $ 26.8 $ 2.6 Prepaid fuel 16.3 14.4 Prepaid insurance and insurance related receivables 12.6 19.3 Prepaid operating expenses 6.8 6.3 Restricted cash - vessel construction obligations 4.9 — Other 7.7 9.0 Total $ 75.1 $ 51.6 Other Long-Term Assets: Other long-term assets consist of the following at December 31, 2018 and 2017: As of December 31, Other Long-Term Assets (in millions) 2018 2017 Income tax receivables $ 21.5 $ 50.2 Vessel and equipment spare parts 13.1 12.7 Insurance related receivables 11.2 12.9 Deferred Charges and other 3.7 7.8 Capital construction fund - cash on deposit (see Note 7) — 0.9 Total $ 49.5 $ 84.5 Impairment of Terminal Joint Venture Investment: The Company’s investment in its Terminal Joint Venture, a related party, is reviewed for impairment annually, or whenever there is evidence that fair value may be below its carrying cost. No impairment was identified during the years ended December 31, 2018, 2017 and 2016. Property and Equipment: Property and equipment are stated at cost. Certain costs incurred in the development of internal-use software are capitalized. Property and equipment is depreciated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of property and equipment range up to the following maximum life: Classification Life Vessels 40 years Machinery and equipment 30 years Terminal facilities 35 years Capitalized Interest: The Company entered into agreements with shipyards for the construction of four new vessels to be utilized within the Company’s operations (see Note 5). The Company is funding the construction of these vessels through borrowings and cash flows generated by the Company. The Company determined that the construction of these vessels are considered qualifying assets for the purposes of capitalizing interest on these assets. The Company’s policy is to capitalize interest costs during the period the qualified assets are being readied for their intended use. The amount of capitalized interest is calculated based on the amount of payments incurred related to the construction of these vessels using a weighted average interest rate. The weighted average interest rate is determined using the Company’s average borrowings outstanding during the period. Capitalized interest is included in vessel construction in progress in property and equipment in the Company’s Consolidated Balance Sheets (see Note 5). During the years ended December 31, 2018, 2017 and 2016, the Company capitalized $18.7 million, $7.5 million and $2.1 million of interest related to the construction of new vessels, respectively. Deferred Dry-docking Costs: U.S. flagged vessels must meet specified seaworthiness standards established by U.S. Coast Guard rules and classification society rules. These standards require U.S. flagged vessels to undergo two dry-docking inspections within a five-year period, with a maximum of 36 months between them. However, U.S. flagged vessels that are enrolled in the U.S. Coast Guard’s Underwater Survey in Lieu of Dry-docking (“UWILD”) program are allowed to have their Intermediate Survey dry-docking requirement met with a less costly underwater inspection. Non-U.S. flag vessels are required to meet applicable classification society rules and their own Port State standards for seaworthiness, which also mandate vessels to undergo two dry-docking inspections every five years. The Company is responsible for maintaining its vessels in compliance with U.S. and international standards. As costs associated with dry-docking inspections provide future economic benefits to the Company through continued operation of the vessels, the costs are deferred and amortized until the next regulatory scheduled dry-docking, which is usually over a two to five-year period. Amortization of deferred dry-docking costs are charged to operating expenses of the Ocean Transportation segment in the Consolidated Statements of Income and Comprehensive Income. Routine vessel maintenance and repairs are charged to expense as incurred. Goodwill and Intangible Assets: Goodwill and intangible assets arise as a result of acquisitions made by the Company (see Notes 6 and 18). Intangible assets consists of customer relationships which are being amortized using the straight-line method over the expected useful lives ranging from 3 to 21 years, and a trade name that has an indefinite life. Impairment of Long-Lived Assets, Intangible Assets and Goodwill : The Company evaluates its long-lived assets, including intangible assets and goodwill for possible impairment in the fourth quarter, or whenever events or changes in circumstances indicate that it is more likely than not that the fair value is less than its carrying amount. The Company has reporting units within the Ocean Transportation and Logistics reportable segments. Long-lived Assets and Finite-lived Intangible Assets: Long-lived assets and finite-lived intangible assets are grouped at the lowest level for which identifiable cash flows are available. In evaluating impairment, the estimated future undiscounted cash flows generated by each of these asset groups is compared with the amount recorded for each asset group to determine if its carrying value is not recoverable. If this review determines that the amount recorded will not be recovered, the amount recorded for the asset group is reduced to its estimated fair value. No impairment charges of long-lived assets and finite-lived intangible assets were recorded for the years ended December 31, 2018, 2017 and 2016. Indefinite-life Intangible Assets and Goodwill: In estimating the fair value of a reporting unit, the Company uses a combination of a discounted cash flow model and fair value based on market multiples of earnings before interest, taxes, depreciation and amortization. Based upon the Company’s evaluation of its indefinite-life intangible assets and goodwill for impairment, the Company determined that the fair value of each reporting unit exceeds book value. No impairment charges of indefinite-life intangible assets and goodwill were recorded for the years ended December 31, 2018, 2017 and 2016. Accruals and other liabilities: Accruals and other liabilities consist of the following at December 31, 2018 and 2017: As of December 31, Accruals and Other Liabilities (in millions) 2018 2017 Payroll and vacation related accruals $ 25.7 $ 24.7 Employee incentives and other related accruals 19.5 17.4 Uninsured risks and related liabilities - short term 9.9 15.4 Deferred revenues 5.7 5.0 Interest on debt 5.1 5.4 Multi-employer withdrawal liabilities - short term (see Note 12) 10.8 4.1 Pension and post-retirement liabilities - short term (see Note 11) 3.0 3.0 Other short-term liabilities 2.2 5.4 Total $ 81.9 $ 80.4 Other long-term liabilities: Other long-term liabilities consist of the following at December 31, 2018 and 2017: As of December 31, Other Long-Term Liabilities (in millions) 2018 2017 Pension and post-retirement liabilities (see Note 11) $ 79.4 $ 75.1 Multi-employer withdrawal liability (see Note 12) 56.6 65.1 Uninsured risks and related liabilities 27.3 29.5 Other long-term liabilities 14.0 8.5 Total $ 177.3 $ 178.2 Pension and Post-Retirement Plans: The Company is a member of the Pacific Maritime Association (“PMA”) and the Hawaii Stevedoring Industry Committee, which negotiate multi-employer pension plans covering certain shoreside bargaining unit personnel. The Company directly negotiates multi-employer pension plans covering other bargaining unit personnel. Pension costs are accrued in accordance with contribution rates established by the PMA, the parties to a plan or the trustees of a plan. Several trusteed, non-contributory, single-employer defined benefit plans and defined contribution plans cover substantially all other employees. The estimation of the Company’s pension and post-retirement benefit expenses and liabilities requires that the Company make various assumptions. These assumptions include factors such as discount rates, expected long-term rate of return on pension plan assets, salary growth, health care cost trend rates, inflation, retirement rates, mortality rates, and expected contributions. Actual results that differ from the assumptions made could materially affect the Company’s financial condition or its future operating results. Additional information about the Company’s pension and post-retirement plans is included in Note 11. Uninsured Risks and Related Liabilities: The Company is uninsured for certain risks but when feasible, many risks are mitigated by insurance. The Company purchases insurance with deductibles or self-insured retentions. Such insurance includes, but is not limited to, employee health, workers’ compensation, marine liability, auto liability and physical damage to inland property, equipment and vessels. For certain risks, the Company elects to not purchase insurance because of excessive cost of insurance or the perceived remoteness of the risk. In addition, the Company retains all risk of loss that exceeds the limits of the Company’s insurance policies. When estimating its reserves for uninsured risks and related liabilities, the Company considers a number of factors, including historical claims experience, demographic factors, current trends, and analyses provided by independent third-parties. Periodically, management reviews its assumptions and estimates used to determine the adequacy of the Company’s reserves for uninsured risks and related liabilities. Leases: The Company recognizes operating lease expense on a straight-line basis over the lease term. The Company’s operating leases are more fully described in Note 9. The Company’s capital leases are de minimis and are included as part of the Company’s debt (see Note 8). Recognition of Revenues and Expenses: Revenue in the Company’s Consolidated Financial Statements is presented net of elimination of intercompany transactions. The following is a description of the Company’s principal revenue generating activities by segment, and the Company’s revenue recognition policy for each activity for the periods presented: Year Ended December 31, Ocean Transportation (in millions) (1) 2018 2017 2016 Ocean Transportation services $ 1,599.3 $ 1,531.8 $ 1,504.5 Terminal and other related services 23.0 23.5 22.9 Fuel sales 12.2 9.9 7.5 Vessel management and related services 6.8 6.6 6.2 Total $ 1,641.3 $ 1,571.8 $ 1,541.1 (1) Ocean Transportation revenue transactions are primarily denominated in U.S. dollars except for less than 3 percent of Ocean Transportation services revenue and fuel sales revenue categories which are denominated in foreign currencies. § Ocean Transportation services revenue is recognized ratably over the duration of a voyage based on the relative transit time completed in each reporting period. Vessel operating costs and other ocean transportation operating costs, such as terminal operating overhead and general and administrative expenses, are charged to operating costs as incurred. § Terminal and other related services revenue is recognized as the services are performed. § Fuel sale revenue is recognized when the Company has completed delivery of the product to the customer in accordance with the terms and conditions of the contract. § Vessel management and related services revenue is recognized in proportion to the services completed. Year Ended December 31, Logistics (in millions) (1) 2018 2017 2016 Transportation Brokerage and Freight Forwarding services $ 549.1 $ 445.1 $ 373.7 Warehouse and distribution services 19.1 17.5 19.7 Supply chain management and other services 13.3 12.5 7.1 Total $ 581.5 $ 475.1 $ 400.5 (1) Logistics revenue transactions are primarily denominated in U.S. dollars except for less than 3 percent of transportation brokerage and freight forwarding services revenue, and supply chain management and other services revenue categories which are denominated in foreign currencies. § Transportation Brokerage and Freight Forwarding services revenue consists of amounts billed to customers for services provided. The primary costs include third-party purchased transportation services, labor and equipment costs. Revenue and the related purchased third-party transportation costs are recognized over the duration of a delivery based upon the relative transit time completed in each reporting period. Labor and other operating costs are expensed as incurred. The Company reports revenue on a gross basis as the Company serves as the principal in these transactions because it is responsible for fulfilling the contractual arrangements with the customer and has latitude in establishing prices. § Warehousing and distribution services revenue consist of amounts billed to customers for storage, handling, and value-added packaging of customer merchandise. Storage revenue is recognized in the month the service is provided to the customer. Storage expenses are recognized as incurred. Other warehousing and distribution services revenue and expense are recognized in proportion to the services performed. § Supply chain management and other services revenue and related costs are recognized in proportion to the services performed. The Company generally invoices its customers at the commencement of the voyage or the transportation service being provided, or as other services are being performed. Revenue is deferred when services are invoiced in advance to the customer. The Company’s receivables are classified as short-term as collection terms are for periods of less than one year. The Company expenses sales commissions and contract acquisition costs as incurred because the amounts are generally immaterial. These expenses are included in selling, general and administration expenses in the Consolidated Statements of Income and Comprehensive Income. Customer Concentration: The Ocean Transportation segment serves customers in numerous industries and carries a wide variety of cargo, mitigating its dependence upon any single customer or single type of cargo. In 2018, 2017 and 2016, the 10 largest Ocean Transportation customers accounted for approximately 24 percent, 23 percent and 24 percent of Ocean Transportation revenue, respectively. None of these customers individually account for more than 10 percent of Ocean Transportation operating revenues. The Logistics segment serves customers in numerous industries and geographical locations. In 2018, 2017 and 2016, the 10 largest logistics customers accounted for approximately 23 percent, 19 percent and 22 percent of Logistics revenue, respectively. None of these customers individually account for more than 10 percent of Logistics operating revenues. Dividends: The Company recognizes dividends as a liability when approved by the Board of Directors. Share-Based Compensation: The Company records compensation expense for all share-based awards made to employees and directors. The Company’s various stock-based compensation plans are more fully described in Note 15. Income Taxes: The Company makes certain estimates and judgments in determining income tax expense for Consolidated Financial Statement purposes. These estimates and judgments are applied in the calculation of taxable income, 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, costs and expenses for tax purposes. Deferred tax assets and liabilities are adjusted to the extent necessary to reflect tax rates expected to be in effect when the temporary differences reverse. The Company records a valuation allowance if, based on the weight of available evidence, management believes that it is more likely than not that some portion or all of a recorded deferred tax asset would not be realized in future periods. Significant changes to these estimates may result in an increase or decrease to the Company’s income taxes in a subsequent period. The Company’s income taxes are more fully described in Note 10. Rounding: Amounts in the Consolidated Financial Statements and Notes to the Consolidated Financial Statements are rounded to millions, except for per-share calculations and percentages which were determined based on amounts before rounding. Accordingly, a recalculation of some per-share amounts and percentages, if based on the reported data, may be slightly different. New Accounting Pronouncements : Leases (Topic 842) (“ASU 2016-02”) : In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02 which requires lessees to record operating and finance leases on their balance sheet and disclose information related to such arrangements. ASU 2016-02 states that a lessee would recognize a lease liability for the lease payment obligation, and a right-of-use asset for the underlying leased asset for the period of the lease term. For an operating lease, the recognition of lease expense in the income statement is expected to be similar to current practice. The new standard is effective for interim and annual periods beginning on or after December 15, 2018. A modified retrospective transition approach is required. The Company will adopt ASU 2016-02 effective January 1, 2019 and plans to make the following elections: · Apply the transition requirements at the effective date of January 1, 2019, with the effects, if any, of initially applying ASU 2016-02 to be recognized as a cumulative-effect adjustment to retained earnings in the period of adoption; · The package of practical expedient permitted under the transition guidance which allows the historical lease classification and initial direct costs to be carried forward; · Elect the short-term lease exception which allows the Company to exclude leases with an initial term of one year or less from recognition; · Elect to separate non-lease components; and · Elect to use a portfolio approach in applying discount rates to leases based upon the lease terms in the following categories: (i) one to five years; (ii) six to ten years; (iii) eleven to fifteen years; and (iv) sixteen years and greater, regardless of the type of asset. The Company plans to use its estimated incremental borrowing rate based on information available at the date of adoption in calculating the present value of its existing lease payments. The incremental borrowing rate will be determined using the U.S. Treasury rate adjusted to account for the Company’s credit rating and the collateralized nature of operating leases. The Company estimates that upon adoption, it will initially record a right-of-use asset of approximately $252.9 million, and a corresponding current and long-term lease liability of approximately $54.2 million and $206.4 million, respectively. The Company will also record a cumulative-effect adjustment of approximately $5.9 million to increase beginning retained earnings at January 1, 2019, as a result of adopting ASU 2016-02. The Company does not believe that the adoption of ASU 2016-02 will have any significant impact on the Company’s current earnings, liquidity or existing debt covenant requirements. The Company’s finance leases and sub-lease income are nominal to the Company’s Consolidated Financial Statements. Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) : In June 2016, the FASB issued ASU 2016‑13 which amends the current approach to estimate credit losses on certain financial assets, including trade and other receivables, available-for-sale securities and other financial instruments. ASU 2016‑13 requires entities to establish a valuation allowance for the expected lifetime losses of certain financial instruments. Subsequent changes in the valuation allowance are recorded in current earnings and reversal of previous losses is permitted. The new standard is effective for interim and annual periods beginning on or after December 15, 2019, and early adoption is permitted. The Company is in the process of evaluating this new standard, but does not expect the adoption of ASU 2016‑13 to have a significant impact on the Company’s Consolidated Financial Statements. Revenues from Contracts with Customers (Topic 606) (“ASU 2014-09”): The Company adopted ASU 2014-09 during the three months ended March 31, 2018 using the modified retrospective method. Prior to adopting ASU 2014-09, the Company performed a review of its revenue contracts and evaluated the Company’s current accounting policies and procedures for recognizing revenues in the Company’s Consolidated Financial Statements, and compared these to the new requirements of ASU 2014-09. In addition, the Company identified the performance obligations and consideration applicable under each contract. Based upon this evaluation, the Company determined that the impact of adopting ASU 2014-09 was de minimis because the analysis of the Company’s contracts under ASU 2014-09 supports the recognition of revenue over time as the service is performed, which is consistent with the Company’s current revenue recognition accounting policy. The majority of the Company’s contracts require the Company to provide ocean and logistics transportation services to its customers. Such services are provided by the Company over a period of time, generally, when cargo is being delivered from source to destination point, or as the service is being performed. These performance obligations are completed in a short period of time due to the nature of the services provided by the Company. Under the new standard, revenues from the majority of the Company’s contracts will continue to be recognized over time as the customer simultaneously receives and consumes the benefit of these services as described in ASU 2014-09. Income Statement – Reporting Comprehensive Income (Topic 220) (“ASU 2018-02”): ASU 2018-02 allows a reclassification from accumulated other comprehensive income (loss) to retained earnings for the remeasurement tax effects resulting from the Tax Act. The Company elected to early adopt ASU 2018-02 during the three months ended March 31, 2018, and recorded a reclassification adjustment of $6.0 million between accumulated other comprehensive income (loss) and retained earnings (see Note 13). Compensation – Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Benefit Cost (“ASU 2017-07”): ASU 2017-07 requires employers that sponsor defined benefit pension and post-retirement plans to present the service cost component of net benefit cost in the same income statement line item as other employee compensation costs arising from services rendered, and that only the service cost component will be eligible for capitalization. The other components of the net periodic benefit cost must be presented separately from the line item that includes the service cost component and outside of the income from operations subtotal. The Company adopted ASU 2017-07 during the three months ended March 31, 2018. To conform prior year amounts to current period presentation as required by ASU 2017-07, the Company recorded retrospective adjustments and reclassified $2.1 million of income and $2.1 million of expense from costs and expenses, to other income (expense), net in the Consolidated Statement of Income and Comprehensive Income for the years ended December 31, 2017 and 2016, respectively. There was no change to income before income taxes for all years presented as a result of adopting ASU 2017‑07. Simplifying the Test for Goodwill Impairment (“ ASU 2017-04”) : ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating step two from the goodwill impairment test. The Company early adopted ASU 2017-04 during the three months ended December 31, 2018. The adoption of this ASU had no impact on the Company’s Consolidated Financial Statements.

REPORTABLE SEGMENTS

REPORTABLE SEGMENTS
REPORTABLE SEGMENTS	3. Reportable 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’s chief operating decision maker is its Chief Executive Officer. The Company consists of two reportable segments, Ocean Transportation and Logistics, which are further described in Note 1. Reportable segments are measured based on operating income. In arrangements where the customer purchases ocean transportation and logistics services, the revenues are allocated to each reportable segment based upon the contractual amounts for each type of service. The Company’s Terminal Joint Venture segment has been aggregated into the Company’s Ocean Transportation segment due to the operations of the Terminal Joint Venture being an integral part of the Company’s Ocean Transportation business (see Note 4). Included in the reportable segment information below are 52 weeks in the 2018 and 2017 fiscal years, and 53 weeks in the 2016 fiscal year. The Company’s Ocean Transportation segment provides ocean transportation services to the Logistics segment, and the Logistics segment provides logistics services to the Ocean Transportation segment. Accordingly, inter-segment revenue of $95.4 million, $81.3 million and $62.0 million for the years ended December 31, 2018, 2017 and 2016, respectively, have been eliminated from Logistics’ operating revenues due to the nature of how those services were performed.

CAPITAL CONSTRUCTION FUND.
CAPITAL CONSTRUCTION FUND	7. The Company is party to an agreement with the U.S. Department of Transportation, Maritime Administration (“MARAD”) that established a Capital Construction Fund (“CCF”) program under provisions of the Merchant Marine Act of 1936, as amended (the “Merchant Marine Act”). The CCF program was created to assist owners and operators of U.S. flag vessels in raising capital necessary for the modernization and expansion of the U.S. merchant marine fleet. CCF funds may be used for the acquisition, construction, or reconstruction of vessels, and for repayment of existing vessel indebtedness through the deferment of federal income taxes on certain deposits of monies and other property placed into the CCF. Qualified withdrawals from the CCF must be used for investment in vessels built in the U.S. and used between covered U.S. ports as described by the Merchant Marine Act, and for other qualifying expenditures (see Item 1 of Part 1 for additional information on Maritime Laws and the Jones Act). Participants of the CCF must also meet certain U.S. citizenship requirements. Deposits into the CCF are limited by certain applicable earnings and other conditions. Such deposits, once made, are available as tax deductions in the Company’s income tax provision. Qualified withdrawals from the CCF do not give rise to a current income tax liability, but reduce the depreciable basis of the vessels or certain related equipment for income tax purposes. However, if withdrawals are made from the CCF for general corporate purposes or other non-qualified purposes, or upon termination of the agreement, they are taxable with interest payable from the year of deposit. Deposits not committed for qualified purposes within 25 years from the date of deposit will be treated as non-qualified withdrawals over the subsequent five years. Under the terms of the CCF agreement, the Company may designate certain qualified earnings as “accrued deposits” or may designate, as obligations of the CCF, qualified withdrawals to reimburse qualified expenditures initially made with operating funds. Such accrued deposits to, and withdrawals from, the CCF are reflected in the Consolidated Balance Sheets either as obligations of the Company’s current assets or as receivables from the CCF. As of December 31, 2018 and 2017, $1.0 million and $134.8 million, respectively, of eligible accounts receivable were assigned to the CCF. Due to the nature of the assignment of eligible accounts receivable into the CCF, such assigned amounts are classified as part of accounts receivable in the Consolidated Balance Sheets. At December 31, 2017, the Company had $0.9 million on deposit in the CCF invested in a money market fund which is classified as other long-term assets in the Company’s Consolidated Balance Sheets. The amount on deposit in the CCF at December 31, 2018 was nominal.

The aggregate borrowing within the Credit Agreement includes a $100 million sublimit for the issuance of standby and commercial letters of credit, and a $50 million sublimit for swing line loans. The Company may prepay any amounts outstanding under the Credit Agreement without premium or penalty. All obligations of the Company under the Credit Agreement are guaranteed by Matson’s principal operating subsidiary MatNav and by certain other subsidiaries. Depending on the Company’s consolidated net leverage ratio, borrowings under the Credit Agreement bear interest at either LIBOR plus a margin of between 1.00 percent and 1.75 percent or the base rate plus a margin of between zero percent and 0.75 percent. Letters of credit are subject to fees based on the Company’s consolidated net leverage ratio at a rate of between 1.00 percent and 1.75 percent. The Company also pays a commitment fee of between 0.15 percent and 0.30 percent depending on the Company’s consolidated net leverage ratio.

Amendments to Existing Private Placement Term Loan Facilities and New Shelf Facilities (“Private Loan Facilities”): On June 29, 2017, the Company and the holders of the Company’s term loans entered into amendments (collectively, the “2017 Amendments”) to each of the term loan agreements and amendments thereto, previously issued prior to the Closing Date. The 2017 Amendments provide for amendments to certain covenants and other terms, including (at the Company’s option under certain circumstances) adjustments to the required consolidated leverage ratio, and, in connection with the exercise of such option, the payment of additional interest for certain pre-defined periods. Interest rates and other substantive terms remained unchanged. Debt Covenants : The Credit Agreement and Private Loan Facilities (collectively, the “Agreements”) contain affirmative, negative and financial covenants customary for financings of this type, including, among other things, limitations on certain other indebtedness, loans and investments, liens, mergers, asset sales, and transactions with affiliates as defined within the Agreements. The Agreements also contain customary events of default. A brief description of the principal covenants contained in the Agreements includes, but is not limited to the following (as defined within the Agreements): § Minimum Consolidated Interest Coverage Ratio as of the end of any fiscal quarter is not permitted to be less than 3.50 to 1.0; § Maximum Consolidated Leverage Ratio as of the end of any fiscal quarter is not permitted to exceed 3.25 to 1.0, subject to the Company’s election of specific exceptions in which the Maximum Consolidated Leverage Ratio is not permitted to exceed 3.75 to 1.0 for certain pre-defined periods as described in the Agreements; § The principal amount of Priority Debt: (i) is not permitted to exceed 20 percent of Consolidated Tangible Assets at any time (subject to a reduction to 17.5 percent upon the earlier of December 31, 2017, or upon the occurrence of certain events), and; (ii) the principal amount of Priority Debt that is not Title XI Priority Debt at any time is not permitted to exceed 10 percent of Consolidated Tangible Assets.

LEASES
LEASES	9. The Company has a variety of different types of operating leases, the specific terms and conditions of which vary from lease to lease. Certain operating lease agreements include terms such as (i) renewal and early termination options; (ii) early buy-out and purchase options; and (iii) rent escalation clauses. The lease agreements also include provisions for the maintenance of the leased asset and payment of lease related costs. The Company reviews the specific terms and conditions of each lease and, as appropriate, notifies the lessor of any intent to exercise any option in accordance with the terms of the lease. In the normal course of business, the Company expects to be able to renew or replace most of its operating leases by other similar leases as they expire. Except for the vessel lease guaranty described below, the Company’s leases do not contain any residual value guarantees. The lease type and estimated maximum terms of the Company’s operating leases are as following: Lease Type: Life Real estate and terminal leases 65 years Vessel charter leases 10 years Operations equipment and other leases 8 years Rent expense recorded in costs and expenses in the Consolidated Statements of Income and Comprehensive Income from operating leases and other non-lease agreements are as follows: Years Ended December 31, (In millions) 2018 2017 2016 Real estate and terminal leases $ 25.6 $ 26.4 $ 25.4 Vessel charter leases 21.4 21.4 16.4 Operations equipment and other leases 26.8 26.0 27.9 Other rent expense 68.1 54.9 49.9 Total $ 141.9 $ 128.7 $ 119.6 Future minimum payments under operating lease agreements at December 31, 2018 are as follows: Year (in millions) Total 2019 $ 68.3 2020 59.2 2021 44.8 2022 34.7 2023 30.5 Thereafter 83.6 Total minimum lease payments $ 321.1 Vessel Charter and Buyer-Lessor Guaranty Vessel Charter: On November 26, 2018, a wholly-owned subsidiary of the Company entered into agreements whereby a vessel, MV Maunalei , owned by the subsidiary, was sold for $106.0 million and subsequently leased back from the buyer-lessor under a Bareboat Charter Agreement (the “Charter”). The transaction qualified for sale and leaseback treatment under ASC 840, Leases , with the Charter treated as an operating lease for accounting purposes. Lease payments are approximately $3.0 million per quarter, and the base term of the Charter is five years with a two year end-of-term renewal option. Total future minimum lease payments were $59.9 million at December 31, 2018, and are included in the future minimum payments table above. The Company recorded a net deferred gain of $2.3 million related to this sale and leaseback during the year ended December 31, 2018, and is included in other long-term liabilities in the Consolidated Balance Sheet. Prior to the expiration of the base term of the Charter, the subsidiary may, at its option, elect to: (i) purchase the vessel at the option price; (ii) exercise the option to renew the Charter for an additional two years; or (iii) remarket the vessel to sell to a third-party on behalf of the buyer-lessor. The purchase option price is $68.9 million after the base term and $58.3 million after the extended term. The Charter also includes a maximum residual value guarantee amount of $50.9 million after five years, or $47.7 million after the extended term. Proceeds from the sale of the vessel reduces the subsidiary’s residual value guarantee. Buyer-Lessor Guaranty: Matson, Inc. provided the buyer-lessor with a guaranty of all obligations of the wholly-owned subsidiary related to the Charter as defined in the guaranty agreement.

INCOME TAXES	10. Income Taxes: On December 22, 2017, the Tax Act was signed into law and included numerous changes in existing tax law, including a reduction in the federal corporate income tax rate from 35 percent to 21 percent. The rate reduction and other changes took effect on January 1, 2018. Other changes such as remeasurement of deferred tax assets and liabilities were effective as of the fourth quarter of 2017. Also, on December 22, 2017, the Securities Exchange Commission (“SEC”) staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. As of December 31, 2018, the Company has completed its assessment of the impact of the Tax Act. In connection with the Company’s analysis of the impact of the Tax Act, the Company recorded a net tax benefit of $154.0 million related to the remeasurement and other discrete adjustments to the Company’s deferred tax assets and liabilities during the year ended December 31, 2017. In addition, the Company recorded a non-cash tax adjustment of $2.9 million that increased current income taxes during the year ended December 31, 2018. This adjustment related to the application of an estimated 6.2 percent sequestration on alternative minimum tax (AMT) refunds for the years 2018 to 2021. On January 19, 2019, the Internal Revenue Service issued new guidance indicating that sequestration would not apply to refundable AMT credits. In accordance with this new guidance, the Company will record a non-cash adjustment of $2.9 million that will reduce current income taxes during the three months ending March 31, 2019. Income taxes for the years ended December 31, 2018, 2017 and 2016 consisted of the following: Years Ended December 31, (In millions) 2018 2017 2016 Current: Federal $ 2.4 $ 21.6 $ 10.5 State 2.1 2.2 (1.3) Discrete adjustments related to the Tax Act (1) 2.9 — — Total 7.4 23.8 9.2 Deferred: Deferred tax expense 31.3 24.4 39.9 Remeasurement and discrete adjustments related to the Tax Act (2) — (154.0) — Total 31.3 (129.6) 39.9 Total income taxes $ 38.7 $ (105.8) $ 49.1 (1) Current income taxes for the year ended December 31, 2018 includes a non-cash income tax expense of $2.9 million, which relates to discrete adjustments as a result of applying the provisions of the Tax Act. (2) Deferred income taxes for the year ended December 31, 2017 includes a non-cash income tax benefit of $154.0 million, which relates to the remeasurement of the Company’s deferred tax assets and liabilities and other discrete adjustments as a result of applying the provisions of the Tax Act. Income taxes for the years ended December 31, 2018, 2017, and 2016, differs from amounts computed by applying the statutory federal rate to income before income taxes for the following reasons: Years Ended December 31, 2018 2017 2016 Computed federal income tax expense 21.0 % 35.0 % 35.0 % State income tax 3.4 % 2.6 % 1.8 % Valuation allowance (0.7) % 1.4 % 0.3 % Foreign taxes 0.6 % 0.1 % 0.4 % Remeasurement and discrete adjustments related to the Tax Act (1) 2.0 % (123.0) % — % Share-based payments 0.1 % (1.4) % — % Other — net (0.2) % 0.8 % 0.1 % Effective income tax rate 26.2 % (84.5) % 37.6 % (1) Effective income tax rate for the year ended December 31, 2018 and 2017 includes the impact of a non-cash income tax expense of $2.9 million, or 2.0 percent, and a non-cash income tax benefit of $154.0 million, or (123.0 percent), respectively, related to the remeasurement of the Company’s deferred assets and liabilities and other discrete adjustments as a result of applying the provisions of the Tax Act. The tax effects of temporary differences that gave rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2018 and 2017, were as follows: As of December 31, (In millions) 2018 2017 Deferred tax assets: Benefit plans $ 45.6 $ 44.2 Federal net operating losses 15.2 21.6 Insurance reserves 5.6 6.8 State net operating losses 7.4 7.4 Foreign losses 5.1 6.6 U.S. State alternative minimum tax credits 5.9 4.2 Allowance for doubtful accounts 1.1 0.9 Other 1.8 1.9 Total deferred tax assets 87.7 93.6 Valuation allowance (11.5) (13.0) Total deferred tax assets, net of valuation allowance 76.2 80.6 Deferred tax liabilities: Basis differences for property and equipment 302.1 254.4 Lease financing 26.0 — Capital Construction Fund 7.0 54.2 Intangibles 38.4 36.4 Deferred revenue 3.0 6.9 Terminal Joint Venture investment 11.4 9.6 Reserves 1.0 2.7 Total deferred tax liabilities 388.9 364.2 Deferred tax liability, net $ 312.7 $ 283.6 The Company’s income taxes payable has been reduced 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 non-vested stock when it vests, measured at the fair market value of the stock at the time of vesting, tax-effected. The net tax benefits from share-based transactions were $2.2 million for 2016, and the portion of the tax benefit related to the excess of the amount reported as the tax deduction over expense was reflected as an increase to additional paid-in-capital in the 2016 Consolidated Statements of Shareholders’ Equity. Valuation Allowance: Valuation allowances recorded against the Company’s foreign income tax net operating losses (“NOLs”) and a portion of the state income tax NOLs were $11.5 million and $13.0 million as of December 31, 2018 and 2017, respectively. The Company believes that it is more likely than not that the benefit from these amounts will not be realized. The Company recorded adjustments to its valuation allowance of ($1.1) million, $1.7 million and $0.4 million during the years ended December 31, 2018, 2017 and 2016, respectively. Net Operating Losses and Tax Credit Carryforwards: The Company’s NOLs and tax credit carryforwards at December 31, 2018 and 2017, were as follows: (In millions) Expiration Date 2018 2017 U.S. Federal income tax NOLs Various dates beginning in 2027 $ 74.5 $ 183.8 U.S. State income tax NOLs Various dates beginning in 2032 $ 189.2 $ 192.3 Foreign income tax NOLs No expiration date $ 18.4 $ 23.7 U.S. State alternative minimum tax credit No expiration date $ 5.9 $ 4.2 The U.S. federal and state income tax NOLs in the Company’s filed income tax returns include unrecognized tax benefits. The deferred tax assets recognized for those NOLs are presented net of these unrecognized tax benefits. As a result of changes in tax legislation, the use of a portion of the Company’s domestic NOL and tax credit carryforwards may be limited in future periods. Further, a portion of the federal and state income tax NOLs and tax credit carryforwards may expire before being applied to reduce future income tax liabilities. Unrecognized Tax Benefits: Total unrecognized benefits represent the amount that, if recognized, would favorably affect the Company’s incomes taxes and effective tax rate in future periods. The Company does not expect a material change in gross unrecognized benefits in the next twelve months. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows: Unrecognized Tax Benefits (in millions) Amount Balance at December 31, 2015 $ 22.1 Changes in tax positions of prior years, net (1.1) Reductions for lapse of statute of limitations (0.6) Balance at December 31, 2016 20.4 Changes in tax positions of prior years, net 1.1 Reductions for lapse of statute of limitations (0.1) Revaluation of unrecognized tax benefits due to the Tax Act (1) (5.5) Balance at December 31, 2017 15.9 Changes in tax positions of prior years, net (0.3) Reductions for lapse of statute of limitations (0.5) Balance at December 31, 2018 $ 15.1 (1) Amount relates to the impact of applying the Tax Act during the year ended December 31, 2017. Included in the balance of unrecognized tax benefits at December 31, 2018 are potential benefits of $13.7 million that, if recognized, would affect the Company’s income taxes and effective tax rate. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits in income taxes. To the extent interest and penalties are not ultimately assessed with respect to the settlement of uncertain tax positions, amounts accrued will be reduced and reflected as a reduction of the Company’s income taxes. Interest accrued related to the balance of unrecognized tax benefits totaled $0.4 million and $0.5 million as of December 31, 2018 and 2017, respectively. The Company is no longer subject to U.S. federal income tax audits for years before 2014. The Company is routinely involved in state, local income and excise tax audits, and foreign tax audits.

PENSION AND POST-RETIREMENT PLANS
PENSION AND POST-RETIREMENT PLANS	11. Non-bargaining Plans: The Company has two funded qualified single-employer defined benefit pension plans that cover certain non‑bargaining unit employees and bargaining unit employees. In addition, the Company has plans that provide certain retiree health care and life insurance benefits to substantially all salaried, non-bargaining employees hired before 2008 and to certain bargaining unit employees. Employees are generally eligible for such benefits upon retirement and completion of a specified number of years of 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. Most non-bargaining retirees pay a portion of the benefit costs. Plan Administration, Investments and Asset Allocations: The Company has a Benefits Investment Committee that meets regularly with investment advisors to establish investment policies, direct investments and select investment options for the qualified plans. The Benefits Investment Committee is also responsible for appointing investment managers and monitoring their performance. The Company’s investment policy permits investments in marketable equity securities, such as domestic and foreign stocks, domestic and foreign bonds, venture capital, real estate investments, and cash equivalents. The Company’s investment policy does not permit direct investment in certain types of assets, such as options or commodities, or the use of certain strategies, such as short selling or the purchase of securities on margin. The Company’s investment strategy for its qualified pension plan assets is to achieve a diversified mix of investments that provides for long-term growth at an acceptable level of risk, and to provide sufficient liquidity to fund ongoing benefit payments. The Company has engaged a number of investment managers to implement various investment strategies to achieve the desired asset class mix, liquidity and risk diversification objectives. The Company’s target and actual asset allocations at December 31, 2018 and 2017 were as follows: Asset Categories Target 2018 2017 Domestic equity securities % % % International equity securities % % % Debt securities % % % Real estate % % % Other and cash % % % Total % % % The Company’s investments in equity securities primarily include domestic large-cap and mid-cap companies, but also includes an allocation to small-cap and international equity securities. Equity investments do not include any direct holdings of the Company’s stock but may include such holdings to the extent that the stock is included as part of certain mutual fund holdings. Debt securities include investment-grade and high-yield corporate bonds from diversified industries, mortgage-backed securities, and U.S. Treasuries. Other types of investments include funds that invest in commercial real estate assets, and to a lesser extent, private equity investments in technology companies. All assets within specific funds are allocated to the target asset allocation of the fund. The expected return on plan assets is principally based on the Company’s historical returns combined with the Company’s long-term future expectations regarding asset class returns, the mix of plan assets, and inflation assumptions. Actual return on plan assets for the periods presented are as follows: Actual Return on Plan Assets Returns One-year return % Three-year return % Five-year return % Long-term average return (since plan inception in 1989) % The Company’s pension plan assets are held in a master trust and are stated at estimated 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. Equity Securities: Domestic and international common stocks are valued by obtaining quoted prices on recognized and highly liquid exchanges. Fixed Income Securities: Corporate bonds and U.S. government treasury and agency securities are valued based upon the closing price reported in the market in which the security is traded. U.S. government agency and corporate asset-backed securities may utilize models, such as a matrix pricing model, that incorporate other observable inputs when broker/dealer quotes are not available, such as cash flow, security structure, or market information. Real Estate, Private Equity and Insurance Contract Interests: The fair value of real estate, private equity and insurance contract interests are determined by the issuer based on the unit values of the funds. Unit values are determined by dividing the fund’s net assets by the number of units outstanding at the valuation date. Fair value for underlying investments in real estate is determined through independent property appraisals. Fair value of underlying investments in private equity is determined based on information provided by the general partner taking into consideration the purchase price of the underlying securities, developments concerning the investee company subsequent to the acquisition of the investment, financial data and projections of the investee company provided by the general partner, and such other factors as the general partner deems relevant. Insurance contracts are principally invested in real estate assets, which are valued based upon independent appraisals. The fair values of the Company’s pension plan assets at December 31, 2018 and 2017 by asset category, were as follows: Fair Value Measurements at December 31, 2018 Quoted Prices in Significant Significant Active Markets Observable Unobservable Asset Category (in millions) Total (Level 1) Inputs (Level 2) Inputs (Level 3) Cash $ 6.2 $ 6.2 $ — $ — Equity securities: U.S. large-cap 50.6 24.9 25.7 — U.S. mid- and small-cap 38.4 25.8 12.6 — International large-cap 18.0 — 18.0 — International small-cap 8.1 — 8.1 — Fixed income securities: U.S. Treasuries 8.0 — 8.0 — Municipal bonds 0.1 — 0.1 — Investment grade U.S. corporate bonds 20.8 — 20.8 — High-yield U.S. corporate bonds 0.5 — 0.5 — Other types of investments: Real estate partnership interests 11.6 — — 11.6 Total $ 162.3 $ 56.9 $ 93.8 $ 11.6 Fair Value Measurements at December 31, 2017 Quoted Prices in Significant Significant Active Markets Observable Unobservable Asset Category (in millions) Total (Level 1) Inputs (Level 2) Inputs (Level 3) Cash $ 6.6 $ 6.6 $ — $ — Equity securities: U.S. large-cap 66.0 28.1 37.9 — U.S. mid- and small-cap 42.6 28.3 14.3 — International large-cap 21.6 — 21.6 — International small-cap 9.5 — 9.5 — Fixed income securities: U.S. Treasuries 8.0 — 8.0 — Municipal bonds 0.1 — 0.1 — Investment grade U.S. corporate bonds 17.5 — 17.5 — High-yield U.S. corporate bonds 3.6 — 3.6 — Other types of investments: Real estate partnership interests 11.1 — — 11.1 Private equity partnership interests 0.1 — — 0.1 Total $ 186.7 $ 63.0 $ 112.5 $ 11.2 The table below presents a reconciliation of all pension plan investments measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the years ended December 31, 2018 and 2017: Fair Value Measurements Using Significant Unobservable Inputs (Level 3) (In millions) Real Estate Private Equity Total Balance at December 31, 2016 $ 10.8 $ 0.1 $ 10.9 Actual return (loss) on plan assets: Assets held at the reporting date 0.3 0.1 0.4 Assets sold during the period 0.5 (0.1) 0.4 Purchases, sales and settlements, net (0.5) — (0.5) Balance at December 31, 2017 11.1 0.1 11.2 Actual return (loss) on plan assets: Assets held at the reporting date 0.5 0.5 1.0 Assets sold during the period 0.5 (0.4) 0.1 Purchases, sales and settlements, net (0.5) (0.2) (0.7) Balance at December 31, 2018 $ 11.6 $ — $ 11.6 Contributions to each of the qualified single-employer defined benefit pension plans are determined annually by the Company’s pension administrative committee, based upon the actuarially determined minimum required contribution under the Employee Retirement Income Security Act of 1974 (“ERISA”), as amended, the Pension Protection Act of 2006, and the maximum deductible contribution allowed for tax purposes. In 2017 and 2016, the Company contributed $3.0 million and $7.5 million, respectively, in pension contributions in these plans. There was no pension contribution to these plans in 2018. The Company’s funding policy is to contribute cash to its pension plans so that it meets at least the minimum contribution requirements. The benefit formulas for employees who are members of collective bargaining units are determined according to the collective bargaining agreements, either using final average pay as the base or a flat dollar amount per year of service. Effective December 31, 2011, the Company froze benefit accruals under the final average pay formula for salaried, non-bargaining unit employees hired before January 1, 2008 and transitioned them to the same cash balance formula for employees hired on or after January 1, 2008. Retirement benefits under the cash balance formula are based on a fixed percentage of employee eligible compensation, plus interest. The plan interest credit rate will vary from year to year based on the ten-year U.S. Treasury rate. Benefit Plan Assets and Obligations: The measurement date for the Company’s benefit plan disclosures is December 31 of each year. The status of the funded qualified defined benefit pension plans and the unfunded post-retirement benefit plans at December 31, 2018 and 2017 are shown below: Post-retirement Pension Benefits Benefits December 31, December 31, (In millions) 2018 2017 2018 2017 Change in Benefit Obligation: Benefit obligation at beginning of year $ 232.1 $ 225.4 $ 27.7 $ 25.2 Service cost 4.4 4.0 0.6 0.5 Interest cost 8.6 9.7 1.0 1.1 Plan participants’ contributions — — 0.9 1.1 Plan settlements — (0.3) — — Actuarial (gain) loss (14.1) 13.9 (6.2) 1.9 Benefits paid, net of subsidies received (12.0) (18.9) (1.8) (2.1) Expenses paid (1.6) (1.7) — — Benefit obligation at end of year 217.4 232.1 22.2 27.7 Change in Plan Assets: Fair value of plan assets at beginning of year 186.7 178.8 — — Actual return on plan assets (10.9) 25.8 — — Plan participants’ contributions — — 0.9 1.1 Plan settlements — (0.3) — — Employer contributions — 3.0 0.9 1.0 Benefits paid, net of subsidies received (12.0) (18.9) (1.8) (2.1) Expenses paid (1.6) (1.7) — — Fair value of plan assets at end of year 162.2 186.7 — — Funded Status and Recognized Liability $ (55.2) $ (45.4) $ (22.2) $ (27.7) Qualified pension and post-retirement benefits plans liabilities recognized in the Consolidated Balance Sheets and expenses recognized in accumulated other comprehensive income (loss) at December 31, 2018 and 2017 were as follows: Post-retirement Pension Benefits Benefits December 31, December 31, (In millions) 2018 2017 2018 2017 Non-current assets $ 0.8 $ 0.5 $ — $ — Current liabilities — — (1.2) (1.2) Non-current liabilities, net (56.0) (45.9) (21.0) (26.5) Total $ (55.2) $ (45.4) $ (22.2) $ (27.7) Net loss, net of taxes $ (61.8) $ (46.9) $ (0.1) $ (4.6) Prior service credit, net of taxes 6.0 6.3 21.8 20.2 Total $ (55.8) $ (40.6) $ 21.7 $ 15.6 The information for qualified defined benefit pension plans with an accumulated benefit obligation in excess of plan assets at December 31, 2018 and 2017 is shown below: (In millions) 2018 2017 Projected benefit obligation $ 215.9 $ 229.9 Accumulated benefit obligation $ 215.6 $ 229.6 Fair value of plan assets $ 159.9 $ 184.7 The estimated net loss and prior service credit for the qualified pension plans that will be amortized from accumulated other comprehensive income (loss) is a net periodic cost of $2.2 million, net of tax, in 2019. The estimated net loss and prior service credit for the post-retirement benefit plans that will be amortized from accumulated other comprehensive income (loss) is a net periodic benefit of $2.8 million, net of tax, in 2019. Unrecognized gains and losses of the post-retirement benefit plans are amortized over five years. Although current health care 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. Components of the net periodic benefit cost and other amounts recognized in other comprehensive income (loss) for the qualified pension plans and the post-retirement benefit plans during 2018, 2017, and 2016 were as follows: Pension Benefits Post-retirement Benefits December 31, December 31, (In millions) 2018 2017 2016 2018 2017 2016 Components of Net Periodic Benefit Cost (Benefit): Service cost $ 4.4 $ 4.0 $ 3.9 $ 0.6 $ 0.5 $ 1.5 Interest cost 8.6 9.7 9.7 1.0 1.1 2.7 Expected return on plan assets (13.5) (13.5) (13.4) — — — Amortization of net loss 4.6 5.1 5.5 1.5 1.2 1.2 Amortization of prior service credit (2.3) (2.3) (2.3) (3.8) (3.8) (1.4) Net periodic benefit cost $ 1.8 $ 3.0 $ 3.4 $ (0.7) $ (1.0) $ 4.0 Other Changes in Plan Assets and Benefit Obligations Recognized in Other Comprehensive Income, net of tax: Net loss (gain) $ 7.8 $ 0.8 $ 1.6 $ (4.7) $ 1.1 $ 1.2 New prior service cost (credit) — — — — — (23.4) Amortization of net loss (3.5) (3.1) (3.3) (1.1) (0.7) (0.8) Amortization of prior service credit 1.7 1.4 1.4 2.8 2.3 0.9 Total recognized in other comprehensive (income) loss $ 6.0 $ (0.9) $ (0.3) $ (3.0) $ 2.7 $ (22.1) Total recognized in net periodic benefit cost and other comprehensive (income) loss $ 7.8 $ 2.1 $ 3.1 $ (3.7) $ 1.7 $ (18.1) The weighted average assumptions used to determine benefit information during 2018, 2017, and 2016, were as follows: Pension Benefits Post-retirement Benefits December 31, December 31, 2018 2017 2016 2018 2017 2016 Discount rate (1) 4.40 % 3.80 % 4.40 % 4.50 % 3.90 % 4.60 % Expected return on plan assets 7.50 % 7.75 % 8.00 % Rate of compensation increase 3.00 % 3.00 % 3.00 % 3.00 % 3.00 % 3.00 % Initial health care cost trend rate: Pre-65 group 6.00 % 6.30 % 6.60 % Post-65 group 6.30 % 6.80 % 7.20 % Ultimate health care cost trend rate 4.40 % 4.40 % 4.40 % Year ultimate health care cost trend rate is reached: Pre-65 group Post-65 group (1) The Company derives a single equivalent rate utilizing a yield curve constructed from a portfolio of high-quality corporate bonds with various maturities. If the assumed health care cost trend rate were increased or decreased one percentage point, the accumulated post-retirement benefit obligation, as of December 31, 2018, 2017, and 2016 and the net periodic post-retirement benefit cost for 2018, 2017 and 2016, would have increased or decreased as follows: Post-retirement Benefits One Percentage Point Increase Decrease (In millions) 2018 2017 2016 2018 2017 2016 Effect on total of service cost and interest cost components $ 0.3 $ 0.3 $ 0.9 $ (0.2) $ (0.2) $ (0.7) Effect on post-retirement benefit obligation $ 2.6 $ 4.0 $ 11.5 $ (2.0) $ (3.0) $ (8.3) Non-qualified Pension Plans: The Company has non-qualified supplemental pension plans covering certain employees and retirees, which provide for incremental pension payments from the Company’s general funds so that total pension benefits would be substantially equal to amounts that would have been payable from the Company’s qualified pension plans if it were not for limitations imposed by income tax law. A few employees and retirees receive additional supplemental pension benefits. Non-qualified pension plan liabilities recognized in the Consolidated Balance Sheets and expenses recognized in accumulated other comprehensive income (loss) at December 31, 2018 and 2017 are as follows: Non-qualified Pension Benefits December 31, (In millions) 2018 2017 Current liabilities $ (1.8) $ (1.8) Non-current liabilities, net (2.4) (2.7) Total $ (4.2) $ (4.5) Net loss, net of taxes $ (0.4) $ (0.6) Prior service credit, net of taxes 0.3 0.3 Total $ (0.1) $ (0.3) Discount rates of 4.0 percent and 3.2 percent were used in determining the 2018 and 2017 non-qualified pension plan obligations, respectively. The estimated net loss and prior service credit for the non-qualified pension plans that will be amortized from accumulated other comprehensive income (loss) in 2019 is nominal. Estimated Benefit Payments: The estimated future benefit payments for the next ten years as of December 31, 2018 were as follows: Non-qualified Pension Pension Post-retirement Year (in millions) Benefits Benefits Benefits (1) 2019 $ 13.2 $ 1.8 $ 1.2 2020 13.5 0.4 1.1 2021 13.8 — 1.2 2022 14.1 0.3 1.2 2023 14.5 1.8 1.2 2024-2028 75.0 0.1 5.8 Total $ 144.1 $ 4.4 $ 11.7 (1) Net of plan participants’ contributions and Medicare Part D subsidies. Defined Contribution Plans: The Company sponsors defined contribution plans that qualify under Sections 401(a) and 401(k) of the Internal Revenue Code. The Company may make discretionary matching contributions equal to a specified percentage of each participant’s 401(k) contributions. For the year ended December 31, 2018, the Company provided matching contributions of up to 3 percent of eligible employee compensation. The Company’s matching contributions expensed in 2018, 2017 and 2016 was $2.4 million, $2.4 million and $2.1 million, respectively. The Company may also provide a discretionary profit sharing contribution under the qualified defined contribution plans, to salaried, non-bargaining unit employees, if both a minimum threshold of Company performance is achieved and the Board has approved the profit sharing contribution. For certain eligible employees, supplemental profit sharing contributions are credited under a non-qualified plan to be paid after separation from service from the Company’s general funds so that total profit sharing contributions would be substantially equal to amounts that would have been contributed to the Company’s qualified defined contribution plans if it were not for limitations imposed by income tax law. Discretionary profit sharing contributions expensed in 2018 and 2017 were $1.4 million and $2.3 million, respectively. There were no discretionary profit sharing contributions expensed in 2016. Multi-employer Bargaining Plans: The Company contributes to multi-employer defined benefit pension plans under the terms of collective-bargaining agreements that cover its bargaining unit employees. Contributions are generally based on amounts paid for union labor or cargo volume. The risks of participating in multi-employer plans are different from single-employer plans because assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of other participating employers. Additionally, if one employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. The multi-employer pension plans are subject to the plan termination insurance provisions of ERISA and are paying premiums to the Pension Benefit Guaranty Corporation (“PBGC”). The statutes provide that an employer who withdraws from, or significantly reduces its contribution obligation to, a multi-employer plan generally will be required to continue funding its proportional share of the plan’s unfunded vested benefits. As of December 31, 2018, the Company’s estimated benefit plan withdrawal obligations were $244.2 million. Except as described in Note 12, no withdrawal obligations have been recorded by the Company in the Consolidated Balance Sheets at December 31, 2018 and 2017, as the Company has no present intention of withdrawing from and does not anticipate termination of any of these plans. Information regarding the Company’s participation in multi-employer pension plans is outlined in the table below. The “EIN/Pension Plan Number” column provides the Employer Identification Number (“EIN”) and the three-digit plan number, if applicable. Unless otherwise noted, the most recent Pension Protection Act zone status available in 2018 and 2017 is for the plan’s year-end at December 31, 2018 and 2017, respectively. 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 in the red zone are generally less than 65 percent funded, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded. The funding improvement plan (“FIP”) or rehabilitation plan (“RP”) column indicates the status which 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.

The pension contribution rate was determined by the plan’s actuary to be necessary to maintain full funding of the pension plan and is fully offset by a reallocation of wages and other benefits. (3) Matson's contributions to these plans commenced after the acquisition of Horizon on May 29, 2015. (4) The Company does not make contributions directly to the Seafarers Pension Plan. Instead, contributions are made to the Seafarers Health and Benefits Plan, and are subsequently re-allocated to the Seafarers Pension Plan at the discretion of the plan Trustee. (5) Represents the expiration date of the collective bargaining agreement. The Company also contributes to multi-employer plans that provide post-retirement health and other benefits other than pensions under the terms of collective-bargaining agreements. Benefits provided to active and retired employees and their eligible dependents under these plans include medical, dental, vision and prescription drug. These plans are not subject to the PBGC plan termination and withdrawal liability provisions of ERISA applicable to multi-employer defined benefit pension plans. Contributions to these multi-employer postretirement health and other benefits were $30.0 million, $27.0 million and $22.5 million in 2018, 2017 and 2016, respectively. Multi-employer Defined Contribution Plans: The Company contributes to six multi-employer defined contribution pension plans. These plans are not subject to the withdrawal liability provisions of ERISA or the PBGC applicable to multi-employer defined benefit pension plans. Contributions made to these plans by the Company were $4.8 million, $5.0 million and $5.3 million in 2018, 2017 and 2016, respectively.

MULTI-EMPLOYER WITHDRAWAL LIABILITY
MULTI-EMPLOYER WITHDRAWAL LIABILITY	12. Horizon ceased all of its operations in Puerto Rico during the first quarter of 2015, which resulted in a mass withdrawal from its multi-employer ILA-PRSSA pension fund. The Company assumed this liability as part of the acquisition of Horizon on May 29, 2015. The Company estimated the mass withdrawal liability based upon the required undiscounted quarterly payment of approximately $1.0 million to be paid to the ILA-PRSSA pension fund over a period which ends in March 2040, discounted to present value using the Company’s incremental borrowing rate. Future estimated annual payments to be paid to the ILA-PRSSA pension fund as of December 31, 2018 were as follows: Year (in millions) Total 2019 $ 4.1 2020 4.1 2021 4.1 2022 4.1 2023 4.1 Thereafter 68.0 Total remaining future undiscounted payments due to the ILA-PRSSA pension fund 88.5 Less: amount representing interest Present value of multi-employer withdrawal liability 60.7 Current portion of multi-employer withdrawal liability (see Note 2) (4.1) Long-term portion of multi-employer withdrawal liability (see Note 2) $ 56.6 Furthermore, the Company assumed a partial withdrawal liability related to the Local 153 Fund of the OPEIU. The partial withdrawal liability resulted from a decline in the number of contribution base units related to the Local 153 Fund caused by Horizon terminating all of its operations in Puerto Rico during the first quarter of 2015. The Company included the estimated partial withdrawal liability of $6.7 million within accruals and other liabilities in the Consolidated Balance Sheet as of December 31, 2018, based upon the expected timing of the payment. The same amount was included in long-term liabilities in the Consolidated Balance Sheet as of December 31, 2017.

SHARE-BASED AWARDS
SHARE-BASED AWARDS	15. The Company has share-based compensation plans which are described as follows: 2016 Incentive Compensation Plan: The 2016 Incentive Compensation Plan (the “2016 Plan”) serves as a successor to the 2007 Incentive Compensation Plan and all other predecessor plans. No further grants will be made under the predecessor stock option plans. Under the 2016 Plan, 2.5 million shares of common stock were reserved for issuance. Shareholders approved the 2016 Plan at the 2016 Annual Meeting of Shareholders. The 2016 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 percent 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 10 years. Stock Issuance Program — Under the Stock Issuance Program, shares of common stock, restricted stock units or performance shares may be granted. Time-based equity awards generally vest ratably over three years. Provided certain three-year performance targets are achieved, performance-based equity awards generally vest on the three-year anniversary date of the grant. 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, under the automatic grant program. Awards of restricted stock units granted under the program generally vest on the one-year anniversary of the grant date. The shares of common stock authorized to be issued under the 2016 Plan may be drawn from 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 in private transactions. Share-based compensation expense and other information related to share-based awards for the years ended December 31, 2018, 2017 and 2016 are as follows: Years Ended December 31, Share-based compensation expense, net of estimated forfeitures (in millions) 2018 2017 2016 Share-based compensation expense $ 12.1 $ 11.1 $ 9.8 Intrinsic value of options exercised $ 0.5 $ 0.7 $ 2.0 Tax benefit realized upon stock vesting $ 2.7 $ 6.8 $ 5.9 Fair value of stock vested $ 10.8 $ 17.3 $ 15.8 As of December 31, 2018, there was no unrecognized compensation cost related to non-vested stock options. As of December 31, 2018, unrecognized compensation cost related to non-vested restricted stock units and performance-based equity awards were $11.6 million. Unrecognized compensation cost is expected to be recognized over a weighted average period of approximately 1.7 years.

FAIR VALUE MEASUREMENTS
FAIR VALUE OF FINANCIAL INSTRUMENTS	16. The Company values its financial instruments based on the fair value hierarchy of valuation techniques for fair value measurements. Level 1 inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 inputs include quoted prices for similar assets and liabilities in active markets and inputs other than quoted prices observable for the asset or liability. Level 3 inputs are unobservable inputs for the 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 uses Level 1 inputs for the fair values of its cash, cash equivalents and restricted cash, and Level 2 inputs for its capital construction fund – cash on deposit, and variable and fixed rate debt. The fair values of cash, cash equivalents and restricted cash, and variable rate debt approximate their carrying values due to the nature of the instruments. The fair value of fixed rate debt is calculated based upon interest rates available for debt with terms and maturities similar to the Company’s existing debt arrangements. The carrying value and fair value of the Company’s financial instruments as of December 31, 2018 and 2017 are as follows: Quoted Prices in Significant Significant Total Active Markets Observable Unobservable Carrying Value Total (Level 1) Inputs (Level 2) Inputs (Level 3) (In millions) December 31, 2018 Fair Value Measurements at December 31, 2018 Cash and cash equivalents $ 19.6 $ 19.6 $ 19.6 $ — $ — Restricted cash 4.9 4.9 4.9 — — Variable rate debt 235.0 235.0 — 235.0 — Fixed rate debt 621.4 584.5 — 584.5 — (In millions) December 31, 2017 Fair Value Measurements at December 31, 2017 Cash and cash equivalents $ 19.8 $ 19.8 $ 19.8 $ — $ — CCF – cash on deposit 0.9 0.9 — 0.9 — Variable rate debt 205.0 205.0 — 205.0 — Fixed rate debt 652.1 651.4 — 651.4 —

SIGNIFICANT ACCOUNTING POLICI_2

SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2018
SIGNIFICANT ACCOUNTING POLICIES
Principles of Consolidation	Principles of Consolidation: The Consolidated Financial Statements include the accounts of Matson, Inc. and all wholly-owned subsidiaries, after elimination of intercompany amounts and transactions. Significant investments in businesses, partnerships, and limited liability companies in which the Company does not have a controlling financial interest, but has the ability to exercise significant influence, are accounted for under the equity method. A controlling financial interest is one in which the Company has a majority voting interest or one in which the Company is the primary beneficiary of a variable interest entity. The Company accounts for its investment in the Terminal Joint Venture using the equity method of accounting (see Note 4). The Consolidated Financial Statements include the accounts and activities of Span Alaska from acquisition date on August 4, 2016 (see Note 18).
Fiscal Period	Fiscal Year: The period end for Matson, Inc. is December 31. The period end for MatNav occurred on the last Friday in December, except for Matson Logistics Warehousing, Inc. whose period closed on December 31. Included in these Consolidated Financial Statements are 52 weeks in the 2018 and 2017 fiscal years, and 53 weeks in the 2016 fiscal year, for MatNav.
Foreign Currency Transactions	Foreign Currency Transactions: The United States (U.S.) dollar is the functional currency for substantially all of the financial statements of the Company’s foreign subsidiaries. Foreign currency denominated assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars at exchange rates existing at the respective balance sheet dates. Translation adjustments resulting from fluctuations in exchange rates are recorded as a component of accumulated other comprehensive loss (gain) within shareholders’ equity. The Company translates the result of operations of its foreign subsidiaries at the average exchange rate during the respective periods. Gains and losses resulting from foreign currency transactions are included in selling, general and administrative costs in the Consolidated Statements of Income and Comprehensive Income.
Use of Estimates	Use of Estimates: The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the amounts reported. Estimates and assumptions are used for, but not limited to: impairment of investments; impairment of long-lived assets, intangible assets and goodwill; capitalized interest; allowance for doubtful accounts; legal contingencies; uninsured risks and related liabilities; accrual estimates; pension and post-retirement estimates; multi-employer withdrawal liabilities; and income taxes. Future results could be materially affected if actual results differ from these estimates and assumptions.
Immaterial Correction of an Error in Previously Issued Financial Statements	Immaterial Correction of an Error in Previously Issued Financial Statements: Subsequent to the filing of the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, the Company determined that it had incurred a partial withdrawal liability related to the Office & Professional Employees International Union (“OPEIU”), Local 153 Pension Fund (the “Local 153 Fund”). The partial withdrawal liability resulted from a decline in the number of contribution base units related to the Local 153 Fund caused by Horizon Lines, Inc. (“Horizon”) terminating all of its operations in Puerto Rico during the first quarter of 2015, prior to the Company acquiring Horizon on May 29, 2015. Accordingly, the Company corrected this error by recording an increase in other long-term liabilities of $6.7 million, a reduction in deferred income taxes of $2.6 million, and a corresponding net adjustment to goodwill of $4.1 million for the years ended December 31, 2015, 2016 and 2017. For the year ended December 31, 2017, the $2.6 million deferred income taxes adjustment was reduced by $1.0 million to reflect the remeasurement tax effects resulting from the Tax Cut and Jobs Act of 2017 (the “Tax Act”). This had the corresponding effect of increasing income taxes and decreasing net income by $1.0 million during the year ended December 31, 2107. There was no impact to net income for any other years presented. The misstatement had no net impact on the Company’s Consolidated Statements of Cash Flows. The Company believes the correction of this error is immaterial to previously issued Consolidated Financial Statements for all prior periods.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash: Cash equivalents consist of highly-liquid investments with original maturities of three months or less. The Company carries these investments at cost, which approximates fair value. Outstanding checks in excess of funds on deposit totaled $16.4 million and $18.7 million at December 31, 2018 and 2017, respectively, and are included in current liabilities in the Consolidated Balance Sheets. Restricted cash relates to amounts that are subject to contractual restrictions and are not readily available. Restricted cash was $4.9 million at December 31, 2018, and is included in prepaid expenses and other assets in the Consolidated Balance Sheet. There were no restricted cash amounts at December 31, 2017.
Accounts Receivable, net	Accounts Receivable, net: Accounts receivable represents amounts due from trade customers arising in the normal course of business. Accounts receivable are shown net of allowance for doubtful accounts receivable in the Consolidated Balance Sheets. At December 31, 2018, and 2017, the Company had assigned $1.0 million and $134.8 million of eligible accounts receivable, respectively, to the Capital Construction Fund (see Note 7).
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts : Allowance for doubtful accounts receivable is established by management based on estimates of collectability. Estimates of collectability are principally based on an evaluation of the current financial condition of the customer and the potential risks to collection, the customer’s payment history and other factors which are regularly monitored by the Company. Changes in the allowance for doubtful accounts receivable for the three years ended December 31, 2018, 2017 and 2016 were as follows: Balance at Expense Write-offs Balance at Year (in millions) Beginning of Year (Recovery) (1) and Other End of Year 2018 $ 4.6 $ 0.8 $ (0.6) $ 4.8 2017 $ 4.2 $ 1.0 $ (0.6) $ 4.6 2016 $ 6.6 $ (0.3) $ (2.1) $ 4.2 (1) Expense is shown net of amounts recovered from previously reserved doubtful accounts.
Prepaid expenses and Other Assets	Prepaid Expenses and Other Assets: Prepaid expenses and other assets consist of the following at December 31, 2018 and 2017: As of December 31, Prepaid Expenses and Other Assets (in millions) 2018 2017 Income tax receivables $ 26.8 $ 2.6 Prepaid fuel 16.3 14.4 Prepaid insurance and insurance related receivables 12.6 19.3 Prepaid operating expenses 6.8 6.3 Restricted cash - vessel construction obligations 4.9 — Other 7.7 9.0 Total $ 75.1 $ 51.6
Other Long-Term Assets	Other Long-Term Assets: Other long-term assets consist of the following at December 31, 2018 and 2017: As of December 31, Other Long-Term Assets (in millions) 2018 2017 Income tax receivables $ 21.5 $ 50.2 Vessel and equipment spare parts 13.1 12.7 Insurance related receivables 11.2 12.9 Deferred Charges and other 3.7 7.8 Capital construction fund - cash on deposit (see Note 7) — 0.9 Total $ 49.5 $ 84.5
Impairment of Terminal Joint Venture Investment	Impairment of Terminal Joint Venture Investment: The Company’s investment in its Terminal Joint Venture, a related party, is reviewed for impairment annually, or whenever there is evidence that fair value may be below its carrying cost. No impairment was identified during the years ended December 31, 2018, 2017 and 2016.
Property and Equipment	Property and Equipment: Property and equipment are stated at cost. Certain costs incurred in the development of internal-use software are capitalized. Property and equipment is depreciated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of property and equipment range up to the following maximum life: Classification Life Vessels 40 years Machinery and equipment 30 years Terminal facilities 35 years
Capitalized Interest	Capitalized Interest: The Company entered into agreements with shipyards for the construction of four new vessels to be utilized within the Company’s operations (see Note 5). The Company is funding the construction of these vessels through borrowings and cash flows generated by the Company. The Company determined that the construction of these vessels are considered qualifying assets for the purposes of capitalizing interest on these assets. The Company’s policy is to capitalize interest costs during the period the qualified assets are being readied for their intended use. The amount of capitalized interest is calculated based on the amount of payments incurred related to the construction of these vessels using a weighted average interest rate. The weighted average interest rate is determined using the Company’s average borrowings outstanding during the period. Capitalized interest is included in vessel construction in progress in property and equipment in the Company’s Consolidated Balance Sheets (see Note 5). During the years ended December 31, 2018, 2017 and 2016, the Company capitalized $18.7 million, $7.5 million and $2.1 million of interest related to the construction of new vessels, respectively.
Deferred Dry-docking Costs	Deferred Dry-docking Costs: U.S. flagged vessels must meet specified seaworthiness standards established by U.S. Coast Guard rules and classification society rules. These standards require U.S. flagged vessels to undergo two dry-docking inspections within a five-year period, with a maximum of 36 months between them. However, U.S. flagged vessels that are enrolled in the U.S. Coast Guard’s Underwater Survey in Lieu of Dry-docking (“UWILD”) program are allowed to have their Intermediate Survey dry-docking requirement met with a less costly underwater inspection. Non-U.S. flag vessels are required to meet applicable classification society rules and their own Port State standards for seaworthiness, which also mandate vessels to undergo two dry-docking inspections every five years. The Company is responsible for maintaining its vessels in compliance with U.S. and international standards. As costs associated with dry-docking inspections provide future economic benefits to the Company through continued operation of the vessels, the costs are deferred and amortized until the next regulatory scheduled dry-docking, which is usually over a two to five-year period. Amortization of deferred dry-docking costs are charged to operating expenses of the Ocean Transportation segment in the Consolidated Statements of Income and Comprehensive Income. Routine vessel maintenance and repairs are charged to expense as incurred.
Goodwill and Intangible Assets	Goodwill and Intangible Assets: Goodwill and intangible assets arise as a result of acquisitions made by the Company (see Notes 6 and 18). Intangible assets consists of customer relationships which are being amortized using the straight-line method over the expected useful lives ranging from 3 to 21 years, and a trade name that has an indefinite life.
Impairment of Long-Lived Assets, Intangible Assets and Goodwill	Impairment of Long-Lived Assets, Intangible Assets and Goodwill : The Company evaluates its long-lived assets, including intangible assets and goodwill for possible impairment in the fourth quarter, or whenever events or changes in circumstances indicate that it is more likely than not that the fair value is less than its carrying amount. The Company has reporting units within the Ocean Transportation and Logistics reportable segments. Long-lived Assets and Finite-lived Intangible Assets: Long-lived assets and finite-lived intangible assets are grouped at the lowest level for which identifiable cash flows are available. In evaluating impairment, the estimated future undiscounted cash flows generated by each of these asset groups is compared with the amount recorded for each asset group to determine if its carrying value is not recoverable. If this review determines that the amount recorded will not be recovered, the amount recorded for the asset group is reduced to its estimated fair value. No impairment charges of long-lived assets and finite-lived intangible assets were recorded for the years ended December 31, 2018, 2017 and 2016. Indefinite-life Intangible Assets and Goodwill: In estimating the fair value of a reporting unit, the Company uses a combination of a discounted cash flow model and fair value based on market multiples of earnings before interest, taxes, depreciation and amortization. Based upon the Company’s evaluation of its indefinite-life intangible assets and goodwill for impairment, the Company determined that the fair value of each reporting unit exceeds book value. No impairment charges of indefinite-life intangible assets and goodwill were recorded for the years ended December 31, 2018, 2017 and 2016.
Accruals and Other Liabilities	Accruals and other liabilities: Accruals and other liabilities consist of the following at December 31, 2018 and 2017: As of December 31, Accruals and Other Liabilities (in millions) 2018 2017 Payroll and vacation related accruals $ 25.7 $ 24.7 Employee incentives and other related accruals 19.5 17.4 Uninsured risks and related liabilities - short term 9.9 15.4 Deferred revenues 5.7 5.0 Interest on debt 5.1 5.4 Multi-employer withdrawal liabilities - short term (see Note 12) 10.8 4.1 Pension and post-retirement liabilities - short term (see Note 11) 3.0 3.0 Other short-term liabilities 2.2 5.4 Total $ 81.9 $ 80.4
Other Long-term Liabilities	Other long-term liabilities: Other long-term liabilities consist of the following at December 31, 2018 and 2017: As of December 31, Other Long-Term Liabilities (in millions) 2018 2017 Pension and post-retirement liabilities (see Note 11) $ 79.4 $ 75.1 Multi-employer withdrawal liability (see Note 12) 56.6 65.1 Uninsured risks and related liabilities 27.3 29.5 Other long-term liabilities 14.0 8.5 Total $ 177.3 $ 178.2
Pension and Post-Retirement Plans	Pension and Post-Retirement Plans: The Company is a member of the Pacific Maritime Association (“PMA”) and the Hawaii Stevedoring Industry Committee, which negotiate multi-employer pension plans covering certain shoreside bargaining unit personnel. The Company directly negotiates multi-employer pension plans covering other bargaining unit personnel. Pension costs are accrued in accordance with contribution rates established by the PMA, the parties to a plan or the trustees of a plan. Several trusteed, non-contributory, single-employer defined benefit plans and defined contribution plans cover substantially all other employees. The estimation of the Company’s pension and post-retirement benefit expenses and liabilities requires that the Company make various assumptions. These assumptions include factors such as discount rates, expected long-term rate of return on pension plan assets, salary growth, health care cost trend rates, inflation, retirement rates, mortality rates, and expected contributions. Actual results that differ from the assumptions made could materially affect the Company’s financial condition or its future operating results. Additional information about the Company’s pension and post-retirement plans is included in Note 11.
Uninsured Risks and Related Liabilities	Uninsured Risks and Related Liabilities: The Company is uninsured for certain risks but when feasible, many risks are mitigated by insurance. The Company purchases insurance with deductibles or self-insured retentions. Such insurance includes, but is not limited to, employee health, workers’ compensation, marine liability, auto liability and physical damage to inland property, equipment and vessels. For certain risks, the Company elects to not purchase insurance because of excessive cost of insurance or the perceived remoteness of the risk. In addition, the Company retains all risk of loss that exceeds the limits of the Company’s insurance policies. When estimating its reserves for uninsured risks and related liabilities, the Company considers a number of factors, including historical claims experience, demographic factors, current trends, and analyses provided by independent third-parties. Periodically, management reviews its assumptions and estimates used to determine the adequacy of the Company’s reserves for uninsured risks and related liabilities.
Leases	Leases: The Company recognizes operating lease expense on a straight-line basis over the lease term. The Company’s operating leases are more fully described in Note 9. The Company’s capital leases are de minimis and are included as part of the Company’s debt (see Note 8).
Recognition of Revenues and Expenses	Recognition of Revenues and Expenses: Revenue in the Company’s Consolidated Financial Statements is presented net of elimination of intercompany transactions. The following is a description of the Company’s principal revenue generating activities by segment, and the Company’s revenue recognition policy for each activity for the periods presented: Year Ended December 31, Ocean Transportation (in millions) (1) 2018 2017 2016 Ocean Transportation services $ 1,599.3 $ 1,531.8 $ 1,504.5 Terminal and other related services 23.0 23.5 22.9 Fuel sales 12.2 9.9 7.5 Vessel management and related services 6.8 6.6 6.2 Total $ 1,641.3 $ 1,571.8 $ 1,541.1 (1) Ocean Transportation revenue transactions are primarily denominated in U.S. dollars except for less than 3 percent of Ocean Transportation services revenue and fuel sales revenue categories which are denominated in foreign currencies. § Ocean Transportation services revenue is recognized ratably over the duration of a voyage based on the relative transit time completed in each reporting period. Vessel operating costs and other ocean transportation operating costs, such as terminal operating overhead and general and administrative expenses, are charged to operating costs as incurred. § Terminal and other related services revenue is recognized as the services are performed. § Fuel sale revenue is recognized when the Company has completed delivery of the product to the customer in accordance with the terms and conditions of the contract. § Vessel management and related services revenue is recognized in proportion to the services completed. Year Ended December 31, Logistics (in millions) (1) 2018 2017 2016 Transportation Brokerage and Freight Forwarding services $ 549.1 $ 445.1 $ 373.7 Warehouse and distribution services 19.1 17.5 19.7 Supply chain management and other services 13.3 12.5 7.1 Total $ 581.5 $ 475.1 $ 400.5 (1) Logistics revenue transactions are primarily denominated in U.S. dollars except for less than 3 percent of transportation brokerage and freight forwarding services revenue, and supply chain management and other services revenue categories which are denominated in foreign currencies. § Transportation Brokerage and Freight Forwarding services revenue consists of amounts billed to customers for services provided. The primary costs include third-party purchased transportation services, labor and equipment costs. Revenue and the related purchased third-party transportation costs are recognized over the duration of a delivery based upon the relative transit time completed in each reporting period. Labor and other operating costs are expensed as incurred. The Company reports revenue on a gross basis as the Company serves as the principal in these transactions because it is responsible for fulfilling the contractual arrangements with the customer and has latitude in establishing prices. § Warehousing and distribution services revenue consist of amounts billed to customers for storage, handling, and value-added packaging of customer merchandise. Storage revenue is recognized in the month the service is provided to the customer. Storage expenses are recognized as incurred. Other warehousing and distribution services revenue and expense are recognized in proportion to the services performed. § Supply chain management and other services revenue and related costs are recognized in proportion to the services performed. The Company generally invoices its customers at the commencement of the voyage or the transportation service being provided, or as other services are being performed. Revenue is deferred when services are invoiced in advance to the customer. The Company’s receivables are classified as short-term as collection terms are for periods of less than one year. The Company expenses sales commissions and contract acquisition costs as incurred because the amounts are generally immaterial. These expenses are included in selling, general and administration expenses in the Consolidated Statements of Income and Comprehensive Income.
Customer Concentration	Customer Concentration: The Ocean Transportation segment serves customers in numerous industries and carries a wide variety of cargo, mitigating its dependence upon any single customer or single type of cargo. In 2018, 2017 and 2016, the 10 largest Ocean Transportation customers accounted for approximately 24 percent, 23 percent and 24 percent of Ocean Transportation revenue, respectively. None of these customers individually account for more than 10 percent of Ocean Transportation operating revenues. The Logistics segment serves customers in numerous industries and geographical locations. In 2018, 2017 and 2016, the 10 largest logistics customers accounted for approximately 23 percent, 19 percent and 22 percent of Logistics revenue, respectively. None of these customers individually account for more than 10 percent of Logistics operating revenues.
Dividends	Dividends: The Company recognizes dividends as a liability when approved by the Board of Directors.
Share-Based Compensation	Share-Based Compensation: The Company records compensation expense for all share-based awards made to employees and directors. The Company’s various stock-based compensation plans are more fully described in Note 15.
Income Taxes	Income Taxes: The Company makes certain estimates and judgments in determining income tax expense for Consolidated Financial Statement purposes. These estimates and judgments are applied in the calculation of taxable income, 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, costs and expenses for tax purposes. Deferred tax assets and liabilities are adjusted to the extent necessary to reflect tax rates expected to be in effect when the temporary differences reverse. The Company records a valuation allowance if, based on the weight of available evidence, management believes that it is more likely than not that some portion or all of a recorded deferred tax asset would not be realized in future periods. Significant changes to these estimates may result in an increase or decrease to the Company’s income taxes in a subsequent period. The Company’s income taxes are more fully described in Note 10.
Rounding	Rounding: Amounts in the Consolidated Financial Statements and Notes to the Consolidated Financial Statements are rounded to millions, except for per-share calculations and percentages which were determined based on amounts before rounding. Accordingly, a recalculation of some per-share amounts and percentages, if based on the reported data, may be slightly different.
New Accounting Pronouncements	New Accounting Pronouncements : Leases (Topic 842) (“ASU 2016-02”) : In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02 which requires lessees to record operating and finance leases on their balance sheet and disclose information related to such arrangements. ASU 2016-02 states that a lessee would recognize a lease liability for the lease payment obligation, and a right-of-use asset for the underlying leased asset for the period of the lease term. For an operating lease, the recognition of lease expense in the income statement is expected to be similar to current practice. The new standard is effective for interim and annual periods beginning on or after December 15, 2018. A modified retrospective transition approach is required. The Company will adopt ASU 2016-02 effective January 1, 2019 and plans to make the following elections: · Apply the transition requirements at the effective date of January 1, 2019, with the effects, if any, of initially applying ASU 2016-02 to be recognized as a cumulative-effect adjustment to retained earnings in the period of adoption; · The package of practical expedient permitted under the transition guidance which allows the historical lease classification and initial direct costs to be carried forward; · Elect the short-term lease exception which allows the Company to exclude leases with an initial term of one year or less from recognition; · Elect to separate non-lease components; and · Elect to use a portfolio approach in applying discount rates to leases based upon the lease terms in the following categories: (i) one to five years; (ii) six to ten years; (iii) eleven to fifteen years; and (iv) sixteen years and greater, regardless of the type of asset. The Company plans to use its estimated incremental borrowing rate based on information available at the date of adoption in calculating the present value of its existing lease payments. The incremental borrowing rate will be determined using the U.S. Treasury rate adjusted to account for the Company’s credit rating and the collateralized nature of operating leases. The Company estimates that upon adoption, it will initially record a right-of-use asset of approximately $252.9 million, and a corresponding current and long-term lease liability of approximately $54.2 million and $206.4 million, respectively. The Company will also record a cumulative-effect adjustment of approximately $5.9 million to increase beginning retained earnings at January 1, 2019, as a result of adopting ASU 2016-02. The Company does not believe that the adoption of ASU 2016-02 will have any significant impact on the Company’s current earnings, liquidity or existing debt covenant requirements. The Company’s finance leases and sub-lease income are nominal to the Company’s Consolidated Financial Statements. Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) : In June 2016, the FASB issued ASU 2016‑13 which amends the current approach to estimate credit losses on certain financial assets, including trade and other receivables, available-for-sale securities and other financial instruments. ASU 2016‑13 requires entities to establish a valuation allowance for the expected lifetime losses of certain financial instruments. Subsequent changes in the valuation allowance are recorded in current earnings and reversal of previous losses is permitted. The new standard is effective for interim and annual periods beginning on or after December 15, 2019, and early adoption is permitted. The Company is in the process of evaluating this new standard, but does not expect the adoption of ASU 2016‑13 to have a significant impact on the Company’s Consolidated Financial Statements. Revenues from Contracts with Customers (Topic 606) (“ASU 2014-09”): The Company adopted ASU 2014-09 during the three months ended March 31, 2018 using the modified retrospective method. Prior to adopting ASU 2014-09, the Company performed a review of its revenue contracts and evaluated the Company’s current accounting policies and procedures for recognizing revenues in the Company’s Consolidated Financial Statements, and compared these to the new requirements of ASU 2014-09. In addition, the Company identified the performance obligations and consideration applicable under each contract. Based upon this evaluation, the Company determined that the impact of adopting ASU 2014-09 was de minimis because the analysis of the Company’s contracts under ASU 2014-09 supports the recognition of revenue over time as the service is performed, which is consistent with the Company’s current revenue recognition accounting policy. The majority of the Company’s contracts require the Company to provide ocean and logistics transportation services to its customers. Such services are provided by the Company over a period of time, generally, when cargo is being delivered from source to destination point, or as the service is being performed. These performance obligations are completed in a short period of time due to the nature of the services provided by the Company. Under the new standard, revenues from the majority of the Company’s contracts will continue to be recognized over time as the customer simultaneously receives and consumes the benefit of these services as described in ASU 2014-09. Income Statement – Reporting Comprehensive Income (Topic 220) (“ASU 2018-02”): ASU 2018-02 allows a reclassification from accumulated other comprehensive income (loss) to retained earnings for the remeasurement tax effects resulting from the Tax Act. The Company elected to early adopt ASU 2018-02 during the three months ended March 31, 2018, and recorded a reclassification adjustment of $6.0 million between accumulated other comprehensive income (loss) and retained earnings (see Note 13). Compensation – Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Benefit Cost (“ASU 2017-07”): ASU 2017-07 requires employers that sponsor defined benefit pension and post-retirement plans to present the service cost component of net benefit cost in the same income statement line item as other employee compensation costs arising from services rendered, and that only the service cost component will be eligible for capitalization. The other components of the net periodic benefit cost must be presented separately from the line item that includes the service cost component and outside of the income from operations subtotal. The Company adopted ASU 2017-07 during the three months ended March 31, 2018. To conform prior year amounts to current period presentation as required by ASU 2017-07, the Company recorded retrospective adjustments and reclassified $2.1 million of income and $2.1 million of expense from costs and expenses, to other income (expense), net in the Consolidated Statement of Income and Comprehensive Income for the years ended December 31, 2017 and 2016, respectively. There was no change to income before income taxes for all years presented as a result of adopting ASU 2017‑07. Simplifying the Test for Goodwill Impairment (“ ASU 2017-04”) : ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating step two from the goodwill impairment test. The Company early adopted ASU 2017-04 during the three months ended December 31, 2018. The adoption of this ASU had no impact on the Company’s Consolidated Financial Statements.
