The Company's effective tax rate increased in 2014 compared to 2013 primarily due to the nondeductibility of merger costs, partly offset by increased tax credits in 2014 and the $2.7 million out-of-period income tax benefits in 2013 (see “Out-of-period income tax benefit”). The Utilities' effective tax rate increased in 2014 compared to 2013 primarily due to the out-of-period income tax benefits. The Company’s and the Utilities' effective tax rate decreased in 2013 compared to 2012 primarily due to $3.5 million lower deferred taxes related to the tax gross-up of AFUDC-equity and a $3.1 million (including $2.7 million related to the Utilities) out-of-period income tax benefit (see “Out-of-period income tax benefit”). The tax effects of book and tax basis differences that give rise to deferred tax assets and liabilities were as follows:

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences are deductible. Based upon historical taxable income and projections for future taxable income, management believes it is more likely than not the Company and the Utilities will realize substantially all of the benefits of the deferred tax assets. As of December 31, 2014, the valuation allowance for deferred tax benefits is not significant. In 2014, the net deferred income tax liability continued to increase primarily as a result of accelerated tax deductions taken for bonus depreciation resulting from the Tax Increase Prevention Act of 2014 and the IRS approval of an accounting method that defers the recognition of Revenue Balance Account income. The Utilities are included in the consolidated federal and Hawaii income tax returns of HEI and are subject to the provisions of HEI’s tax sharing agreement, which determines each subsidiary’s (or subgroup's) income tax return liabilities and refunds on a standalone basis as if it filed a separate return (or subgroup consolidated return). Consequently, although HEI consolidated does not expect any unutilized net operating loss (NOL) as of December 31, 2014, standalone Hawaiian Electric consolidated expects an unutilized NOL for federal tax purposes in accordance with the HEI tax sharing agreement. The deferred tax asset associated with this NOL is $52 million and is included in “Prepayments and other.” HEI consolidated. In 2014, 2013 and 2012, credit adjustments to interest expense on income taxes was reflected in “Interest expense – other than on deposit liabilities and other bank borrowings” in the amount of $1.7 million, $0.3 million and $1.4 million, respectively. The credit adjustments to interest expense were primarily due to the resolution of tax issues with the Internal Revenue Service (IRS). As of December 31, 2014 and 2013, the total amount of accrued interest related to uncertain tax positions and recognized on the balance sheet in “Interest and dividends payable” was nil and $0.4 million, respectively. As of December 31, 2014, the total amount of liability for uncertain tax positions was nil. Hawaiian Electric consolidated. In 2014, 2013 and 2012, credit adjustments to interest expense on income taxes was reflected in “Interest and other charges” in the amount of $0.7 million, $0.3 million and $0.5 million, respectively. The credit adjustments to interest expense were primarily due to the resolution of tax issues with the IRS. As of December 31, 2014 and 2013, the total amount of accrued interest related to uncertain tax positions was nil. As of December 31, 2014, the total amount of liability for uncertain tax positions was nil. The changes in total unrecognized tax benefits were as follows:

The 2012 reduction in unrecognized tax benefits was primarily due to the IRS’s acceptance of the deductibility of costs of repairs to utility generation property for tax years 2007-2009. In 2014, the IRS completed its examination of the Company’s federal income tax returns for tax years 2010 and 2011. The Company and the IRS reached an agreement on all adjustments, primarily related to depreciation, and the Congressional Joint Committee on Taxation approved the resulting tax adjustments in October 2014. The income statement impact of the agreement was not material. Tax years 2007, 2009, and 2010 to 2013 remain subject to examination by the Department of Taxation of the State of Hawaii. As of December 31, 2014, the disclosures above present the Company’s and the Utilities' accruals for potential tax liabilities and related interest. Based on information currently available, the Company and the Utilities believe these accruals have adequately provided for potential income tax issues with federal and state tax authorities and related interest, and that the ultimate resolution of tax issues for all open tax periods will not have a material adverse effect on its results of operations, financial condition or liquidity. Out-of-period income tax benefit. During 2013, the Company recorded a $3.1 million (including $2.7 million related to the Utilities) out-of-period income tax benefit, resulting primarily from the reversal of deferred tax liabilities due to errors in the amount of book over tax basis differences in plant and equipment. Management concluded that this out-of-period adjustment was not material to either the current or any prior period financial statements. Recent tax developments. In September 2013, the IRS issued final regulations addressing the acquisition, production and improvement of tangible property, which are effective January 1, 2014. Management evaluated the impact of these new regulations, and does not expect a material impact on the Utilities since specific guidance on network (i.e., transmission and distribution) assets and generation property has already been received and accounted for in its tax computations. The IRS also proposed regulations addressing the disposition of property. The Utilities adopted the safe harbor guidelines with respect to network assets in 2011 and in June 2013, the IRS released a revenue procedure relating to deductions for repairs of generation property, which provides some guidance (that is elective) for taxpayers that own steam or electric generation property. This guidance defines the relevant components of generation property to be used in determining whether such component expenditures should be deducted as repairs or capitalized and depreciated by taxpayers. The revenue procedure also provides an extrapolation methodology that could be used by taxpayers in determining deductions for prior years’ repairs without going back to the specific documentation of those years. The guidance does not provide specific methods for determining the repairs amount. Management intends to adopt a method consistent with this guidance in its 2014 tax return.
