After considering all evidence, both positive and negative, with respect to our federal tax loss carryback availability, expected levels of pre-tax financial statement income, and federal taxable income, we believe it is more likely than not that the existing deductible temporary differences will reverse during periods in which we generate net federal taxable income or have adequate federal carryback availability. As a result, we have no valuation allowance recognized for federal deferred tax assets at December 31, 2014 or 2013.

As of December 31, 2014, we had federal tax net operating loss carryforwards (“NOL”) of $6.1 million. These NOLs, which are subject to an annual limitation of $1.9 million, will expire between 2029 and 2031 as follows:

Our alternative minimum tax credits, which are available to offset future regular taxable income, can be carried forward for an unlimited period of time.
 
Stockholders' equity reflects tax benefits related to compensation expense deductions for share-based compensation awards of $20.2 million at December 31, 2014, $19.2 million at December 31, 2013, and $17.7 million at December 31, 2012.
 
We have analyzed our tax positions in all open tax years, which as of December 31, 2014 were 2011 through 2013. The IRS recently completed a limited scope examination of the 2007 through 2010 tax years, which resulted in no material changes. We do not have unrecognized tax expense or benefit as of December 31, 2014.

In addition, we believe our tax positions will more likely than not be sustained upon examination, including related appeals or litigation. In the event we had a tax position that did not meet the more likely than not criteria, any tax, interest, and penalties incurred related to such a position would be reflected in "Total federal income tax expense (benefit)" on our Consolidated Statements of Income.
