Deferred tax balances arise from temporary differences between the carrying amount of assets and liabilities and their tax basis and are stated at the enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided against deferred tax assets when it is more likely than not that some or all of the deferred tax asset will not be realized. In determining if the Company's deferred tax assets are realizable, management considers all positive and negative evidence, including the history of generating financial reporting earnings, future reversals of existing taxable temporary differences, projected future taxable income, as well as any tax planning strategies. As discussed in Note 2, the Company recognized deferred income tax assets of $8.9 million associated with the correction of an immaterial misstatement with the medical and dental benefits provided to employees and their eligible dependents on long-term disability. The Company believes it is more likely than not that the results of future operations will generate sufficient taxable income to realize the net deferred tax assets.
As of March 31, 2017, the Company has no State net operating loss or NOL carryforwards.
Uncertain Tax Positions
The Company maintains reserves for uncertain tax positions related to income tax benefits recognized. These reserves involve considerable judgment and estimation and are evaluated by management based on the best information available including changes in tax laws and other information. As of March 31, 2017, 2016, and 2015, the Company has recorded $11.6 million, $1.5 million, and $58.4 million, respectively, of reserves for uncertain tax positions which includes potential tax benefits of $1.4 million, $1.4 million, and $55.2 million respectively, that, when recognized, impact the effective tax rate. As discussed in Note 4, the Company has a pre-acquisition tax uncertainty that was recorded in purchase accounting in the amount of $10.2 million.
For the fiscal year ended March 31, 2016, the Company's reserves for uncertain tax positions decreased primarily as a result of expired statute of limitations for a prior tax year and management's conclusion that the uncertain tax positions related to the statute lapse were effectively settled. The Company released approximately $56.9 million of its pre-acquisition uncertain tax positions during fiscal 2016, including $3.2 million of net interest and penalties that were incurred by the Company subsequent to the acquisition. This resulted in a decrease in the Company's effective tax rate for fiscal 2016. As part of this settlement, an amount of $21.4 million, previously indemnified under the remaining available DPO was relieved. As of March 31, 2016, there were no estimated tax indemnified amounts recorded against the DPO.
