The total amount of gross unrecognized tax benefit that would reduce the Company's effective tax rates at March 31, 2014 and March 31, 2013 was $1.3 million and $1.2 million, respectively. The $0.1 million increase in the gross unrecognized tax benefits from March 31, 2013 to March 31, 2014 resulted from an increase in ASC 740-10-25-6, Accounting for Uncertainty in Income Taxes, reserves related to previous year tax positions. Accrued interest expense included with accrued income taxes in the Company's Condensed Consolidated Statements of Financial Position was approximately $0.1 million at both March 31, 2014 and December 31, 2013.

As of March 31, 2014, the Company is no longer subject to U.S. Federal examination by tax authorities for tax years before 2011. The Company is subject to state and local examinations for tax years of 2009 through 2013. In addition, the Company is subject to non-U.S. income tax examinations for tax years of 2008 through 2013.
