At December 31, 2015, the Company had federal and state tax net operating loss carryforwards of approximately $96.5 million and $37.1 million, respectively. These amounts include share-based compensation for federal and state of $22.9 million and $3.8 million, that will be recorded to contributed capital when realized. The federal and state tax loss carryforwards will begin to expire in 2020 and 2016, respectively, unless previously utilized.
At December 31, 2015, the Company had federal and state tax credit carryforwards of approximately $33.2 million and $37.0 million, respectively. The federal tax credit carryforward will begin to expire in 2020, unless previously utilized. The state tax credits do not expire. In addition, the Company has federal alternative minimum tax credit carryforwards of $1.0 million that can be carried forward indefinitely.
The Company evaluated its net deferred income taxes, which included an assessment of the cumulative income or loss over the prior three-year period and future periods, to determine if a valuation allowance is required. After considering its recent history of losses and management's expectations of additional near-term losses, the Company recorded a valuation allowance on its net federal and state deferred tax assets net of deferred tax liabilities related to indefinite-lived intangibles for which no future realization can be expected. During 2015, the Company maintained a valuation allowance against all of its federal and state deferred tax assets as realization of such assets does not meet the more-likely-than-not threshold required under accounting guidelines. The Company will continue to assess the need for a valuation allowance on the deferred tax assets by evaluating positive and negative evidence that may exist.
The change in valuation allowance during 2015 related to operations was $14.9 million. Additionally, the Company completed the acquisition of Entropic in the second quarter. As a result of the acquisition, there was a valuation allowance release resulting in a tax benefit of $1.8 million.
At December 31, 2015, the Company’s unrecognized tax benefits totaled $26.1 million, $20.7 million of which, if recognized at a time when the valuation allowance no longer exists, would affect the effective tax rate. The Company will recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. At December 31, 2015, the Company had accrued approximately $0.1 million of interest and penalties. The Company expects a decrease to its unrecognized tax benefits of $0.1 million within twelve months.
The following table summarizes the changes to the unrecognized tax benefits during 2015, 2014 and 2013:

However, to the extent allowed by law, the tax authorities may have the right to examine prior periods where net operating losses or tax credits were generated and carried forward, and make adjustments up to the amount of the net operating loss or credit carryforward amount.
