In assessing the realizability of our deferred tax assets, we consider future taxable income expected to be generated by the projected differences between financial statement depreciation and tax depreciation, cumulative earnings generated to date and other evidence available to us. Based upon this consideration, we assessed that all of our deferred taxes are more likely than not to be realized, and, as such, we have not recorded a valuation allowance as of December 31, 2015 or 2014.

There were no unrecognized tax benefits as of December 31, 2015 or 2014 and we do not anticipate significant changes to our unrecognized tax benefits within the next twelve months.

Our major tax jurisdictions include U.S. federal and various U.S. states. Tax years that remain open for examination by the Internal Revenue Service ("IRS") include the years from 2012 through 2015. Tax years remaining open in states where we have a significant presence range from 2011 to 2015. In addition, tax years 2003 and 2008 are eligible for examination by the IRS and state tax jurisdictions due to our utilization of the NOLs generated in these tax years in our tax returns.
