9. Taxes

The effective tax rate increased to 42.6% for the six-month period ended June 30, 2013, from 37.8% for the six-month period ended June 30, 2012. This increase for the six-month period ended June 30, 2013, as compared to the same period of 2012, resulted primarily from certain nondeductible transaction costs anticipated during 2013 in relation to the pending Merger.

During the six-month period ended June 30, 2013, the Company’s unrecognized tax benefits for certain tax contingencies decreased from $1.3 million as of December 31, 2012, to $1.2 million as of June 30, 2013. The decrease is primarily attributable to the settlement of various state income tax audits. If recognized, the $1.2 million in unrecognized tax benefits would reduce the Company’s effective tax rate in future periods. Income taxes paid for the six-month periods ended June 30, 2013 and 2012, were $21.7 million and $19.0 million, respectively.
