The effective rate for the three months ended December 31, 2013 increased as compared to the same prior year period primarily due to the increase of the blended state effective tax rates and the non-deductible portion of the impairment charge, offset by the net benefit from the federal research and development tax credit and a benefit in qualified production activities deduction.

The effective tax rates were 33.4% and 34.2% for the nine months ended December 31, 2013 and 2012, respectively. The effective rate for the nine months ended December 31, 2013 decreased as compared to the same prior year period due to a net benefit from the federal research and development tax credit and a benefit in qualified production activities deduction, offset by the non-deductible portion of the impairment charge.

Uncertain tax positions As of December 31, 2013, the Company had recorded a liability of $1.2 million for unrecognized tax benefits related to various federal, state and local income tax matters. If recognized, this amount would reduce the Company’s effective tax rate. The tax liability for the nine months ended December 31, 2013 increased from the same prior year period by $0.6 million due to additional local income tax contingent liability and certain tax positions related to acquired companies. The Company is no longer subject to U.S. federal income tax examinations for tax years before 2012. With few exceptions, the Company is no longer subject to state income tax examinations for tax years before 2008. The Company does not anticipate that total unrecognized tax benefits will significantly change due to the settlement of audits or the expiration of statute of limitations within the next twelve months.
