Total deferred tax liabilities |  | (21,692 | ) |  | (27,957 | ) |  | (17,588 | )
Valuation allowance |  | (1,896 | ) |  | (1,613 | ) |  | (1,627 | )

At June 30, 2018, the Company had approximately $124.9 million in federal and $103.1 million in state net operating loss carryforwards that will begin to expire in the years ending June 30, 2030 and June 30, 2018, respectively. Additionally, at June 30, 2018, the Company had $0.8 million of federal business tax credits that begin to expire in June 30, 2025 and approximately $1.8 million of federal alternative minimum tax credits that do not expire. Under previous accounting rules related to share-based compensation, the Company recognized windfall tax benefits associated with the exercise of share-based compensation directly to stockholders' equity when realized. Accordingly deferred tax assets were not recognized for net operating loss carryforwards resulting from windfall tax benefits prior to June 30, 2017. As discussed in Note 2, the Company adopted ASU 2016-09 beginning on July 1, 2017. Upon adoption, the Company recorded a $1.6 million increase to deferred tax assets and a corresponding increase to retained earnings. At June 30, 2018, the Company had total deferred tax assets of $62.9 million and net deferred tax assets before valuation allowance of $41.2 million. The Company considered whether a valuation allowance should be recorded against deferred tax assets based on the likelihood that the benefits of the deferred tax assets would or would not ultimately be realized in future periods. In making such assessment, significant weight was given to evidence that could be objectively verified such as recent operating results and less consideration was given to less objective indicators such as future income projections. After consideration of positive and negative evidence, including the recent history of income, the Company concluded that it is more likely than not that the Company will generate future income sufficient to realize the majority of the Company’s deferred tax assets as of June 30, 2018. As of June 30, 2018, the Company cannot conclude that certain state net operating loss carry forwards and tax credit carryovers will be utilized before expiration. Accordingly, the Company will maintain a valuation allowance of $1.9 million to offset this deferred tax asset. The valuation allowance increased $0.3 million and decreased $71.7 million, in fiscal 2018 and 2016, respectively. There was no change to the valuation allowance in fiscal 2017. Total unrecognized tax benefits attributable to uncertain tax positions taken in tax returns in each of fiscal 2018, 2017 and 2016 were zero and at June 30, 2018 and 2017, the Company had no unrecognized tax benefits. The Company files income tax returns in the U.S. and in various state jurisdictions with varying statutes of limitations. The Company is no longer subject to U.S. income tax examinations for the fiscal years prior to June 30, 2014. The Internal Revenue Service completed its examination of the Company's tax years ended June 30, 2013 and 2014 and accepted the returns as filed. The Company’s policy is to recognize interest expense and penalties related to income tax matters as a component of income tax expense. In each of the fiscal years ended June 30, 2018 and 2017, the Company recorded $0 in accrued interest and penalties associated with uncertain tax positions. Additionally, the Company recorded income of $0 related to interest and penalties on uncertain tax positions in the fiscal years ended June 30, 2018, 2017 and 2016, respectively. On December 22, 2017, the President of the United States signed into law the Tax Act. The SEC subsequently issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. Under SAB 118, companies are able to record a reasonable estimate of the impacts of the Tax Act if one is able to be determined and report it as a provisional amount during the measurement period. The measurement period is not to extend beyond one year from the enactment date. Impacts of the Tax Act that a company is not able to make a reasonable estimate for should not be recorded until a reasonable estimate can be made during the measurement period. Pursuant to the Tax Act, the federal corporate tax rate was reduced to 21.0%, effective January 1, 2018. Accordingly, the Company adjusted its federal statutory rate to 28.1% for the fiscal year ended June 30, 2018. Deferred tax amounts are calculated based on the rates at which they are expected to reverse in the future. The Company is still analyzing certain aspects of the Tax Act and refining its calculations which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. In connection with the initial analysis of the impact of the Tax Act, the Company has recorded a provisional net tax adjustment of $18.0 million, related to the reduction in the corporate tax rate. While the Company is able to make a reasonable estimate of the impact of the reduction in corporate rate, it may be affected by other analyses related to the Tax Act, including, but not limited to, changes to IRC section 162(m), which the Company is not yet able to reasonably estimate the effect of this provision of the Tax Act. Therefore, the Company has not made any adjustments related to IRC section 162(m) in its consolidated financial statements. Adjustments will be made to the initial assessment as the Company completes the analysis of the Tax Act, collects and prepares necessary data, and interprets any additional guidance.
