Income Taxes:	(10) Income Taxes: In connection with the Separation, the Company entered into a Tax Sharing Agreement with A&B that governs the respective rights, responsibilities and obligations of the companies after the Separation with respect to tax liabilities and benefits, tax attributes, tax contests and other tax sharing regarding U.S. Federal, state, local and foreign income taxes, other tax matters and related tax returns. A&B has liability to Matson with respect to Matson’s consolidated or combined federal, state, local and foreign income tax liability for the taxes that are attributed to A&B’s businesses and relative contribution to state and other taxable income of the Matson consolidated or combined group relating to the taxable periods in which A&B was a part of that group. The Tax Sharing Agreement specifies the portion, if any, of this tax liability for which Matson and A&B will bear responsibility, and Matson and A&B agreed to indemnify each other against any amounts for which they are not responsible. The Company makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments are applied in the calculation of tax credits, tax benefits and deductions, and in the calculation of certain deferred tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. Deferred tax assets and deferred tax liabilities are adjusted to the extent necessary to reflect tax rates expected to be in effect when the temporary differences reverse. Adjustments to deferred tax assets and deferred tax liabilities may be required due to changes in tax laws and audit adjustments by tax authorities. To the extent adjustments are required in any given period, the adjustments would be included within the tax provision in the Condensed Consolidated Statements of Income and Comprehensive Income or Balance Sheets.
