During the three months ended March 31, 2016, and 2015, the Company recorded an increase in unrecognized tax benefits in the amount of $1,843 and $2,695, respectively. The Company anticipates additional increases to its unrecognized tax benefits of $5,000 to $7,000 in the next twelve months. The Company expects that the majority of the increase in its unrecognized tax benefits will not impact the effective tax rate.

The Company files income tax returns in the U.S. federal jurisdiction and various states. With few exceptions, the Company is no longer subject to U.S. federal income tax examinations by tax authorities for years 2011 and prior. Tax years 2012 through 2014 are open to federal examination by the Internal Revenue Service (“IRS”). The Company does not expect significant increases or decreases to unrecognized tax benefits relating to federal, state, or local audits.
