As of December 31, 2016, we had approximately $61.0 million of net operating loss carry forwards and amortization related to intangible assets related to acquisitions that can be used to offset our income for federal and state tax purposes, which expire between 2020 and 2036. Utilization of net operating loss carryforwards is dependent on generating future taxable income of the appropriate type and in the appropriate jurisdiction. In addition, as a result of transactions consummated during 2012 and 2013, including the issuance of common and preferred stock and the acquisitions of Seesmart and Relume, substantially all of our net operating loss carryforwards since December 31, 2013 are subject to limitations imposed by Section 382 of the Internal Revenue Code. During 2013, we performed an evaluation of the Section 382 limitations on the use of net operating loss carryforwards and adjusted them accordingly. We have recognized a full valuation allowance related to our remaining net deferred tax assets, including the remaining net operating loss carryforwards.
Components of deferred tax assets (liabilities) are as follows:
In accordance with ASC 740, valuation allowances are provided against deferred tax assets if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
For the year ended December 31, 2016, we recorded a provision for income taxes of less than $0.1 million related to AMT taxes as the deferred tax benefits of the net losses were offset by a corresponding increase in the deferred tax valuation allowance.
The following is a reconciliation of tax computed at the statutory federal rate to the income tax expense in the statements of operations for the years ended December 31, 2016, 2015, and 2014:
