6.             Income Tax

As of June 30, 2013, the Company had U.S. federal and state net operating loss carryforwards of $3.2 million and $17.7 million, respectively. These net operating loss carryforwards expire at various times beginning in 2022 through 2033. The Company also had alternative minimum tax credit carryforwards of $0.7 million. The Company establishes valuation allowances when necessary to reduce deferred tax assets to amounts expected to be realized. During second quarter 2013, the Company determined that it is more likely than not that the benefit from certain federal and state loss carryforwards and the benefit from certain alternative minimum tax credit carryforwards will not be realized prior to expiration due to the attribute reduction required for the Company’s emergence from bankruptcy during the current period. The Company recorded a valuation allowance of $1.4 million related to the deferred tax asset associated with the federal and state loss carryforwards and a valuation allowance of $0.7 million related to the deferred tax asset associated with the alternative minimum tax credit carryforwards which are expected to not be utilized during the current tax year. No valuation allowance was present in periods prior to the three-month period ended June 30, 2013.

The effective income tax rate as of June 30, 2012 and 2013 was 16.5% and 4.3%, respectively. The 2012 rate differs from the 35% federal statutory rate primarily due to certain non-deductible impairment expenses. The cancellation of debt income in 2013 is non-taxable, and is the primary difference between the 35% federal statutory rate and the effective tax rate.
