The total amount of gross unrecognized tax benefit that would reduce the Company's effective tax rates at March 31, 2013 and March 31, 2012, was $1.2 million and $0.5 million, respectively. The $0.7 million increase in the gross unrecognized tax benefits from March 31, 2012 to March 31, 2013 resulted from an increase in ASC 740-10-25-6, Accounting for Uncertainty in Income Taxes, reserves related to acquired businesses and previous year tax positions. Accrued interest expense included with accrued income taxes in the Company's Condensed Consolidated Statements of Financial Position was less than $0.1 million at March 31, 2013 and December 31, 2012.
