INCOME TAXES

The Tax Cuts and Jobs Act (the "Tax Act") was enacted on December 22, 2017. The Tax Act makes broad and complex changes to the U.S. tax code, including a permanent reduction in the U.S. federal corporate income tax rate to 21% starting in 2018. Previously, the Company was subject to a 34% U.S. federal corporate income tax rate.

Income tax expense for the three and six months ended June 30, 2018 and June 30, 2017 varies from the amount that would result by applying the applicable U.S. federal corporate income tax rate of 21% and 34%, respectively, to loss from continuing operations before income tax expense. The following table summarizes the differences:

The Company maintains a valuation allowance for its gross deferred tax assets at June 30, 2018 and December 31, 2017. The Company's operations have generated substantial operating losses in prior years. These losses can be available to reduce income taxes that might otherwise be incurred on future taxable income; however, it is uncertain whether the Company will generate the taxable income necessary to utilize these losses or other reversing temporary differences. This uncertainty has caused management to place a full valuation allowance on its June 30, 2018 and December 31, 2017 net deferred tax asset, excluding the deferred income tax asset and liability amounts set forth in the paragraph below.

The Company carries net deferred income tax liabilities of $28.8 million and $28.8 million at June 30, 2018 and December 31, 2017, respectively. At June 30, 2018, $8.0 million relates to deferred income tax liabilities scheduled to reverse in periods after the expiration of the Company's consolidated U.S. net operating loss carryforwards, $20.9 million relates to deferred income tax liabilities associated with land and indefinite lived intangible assets and $0.1 million relates to deferred income tax assets associated with alternative minimum tax credits. At December 31, 2017, $8.0 million relates to deferred income tax liabilities scheduled to reverse in periods after the expiration of the Company's consolidated U.S. net operating loss carryforwards, $20.9 million relates to deferred income tax liabilities associated with land and indefinite lived intangible assets and $0.1 million relates to deferred income tax assets associated with alternative minimum tax credits. The Company considered a tax planning strategy in arriving at its June 30, 2018 and December 31, 2017 net deferred income tax liabilities.

As of June 30, 2018 and December 31, 2017, the Company carried a liability for unrecognized tax benefits of $1.4 million and $1.4 million, respectively, that is included in income taxes payable in the consolidated balance sheets. The Company classifies interest and penalty accruals, if any, related to unrecognized tax benefits as income tax expense. The Company recorded income tax expense of $0.1 million and $0.2 million related to interest and penalty accruals for the three months ended June 30, 2018 and June 30, 2017, respectively ($0.1 million and $0.4 million for the six months ended June 30, 2018 and June 30, 2017, respectively).
