During the three months ended March 31, 2015, gross unrecognized tax benefits decreased by $19.5 million to $81.1 million. The decrease primarily relates to the resolution of certain state tax matters. If recognized, approximately $80.0 million of the $81.1 million in unrecognized tax benefits would affect our effective tax rate and net earnings in future periods. 
We recognize interest and penalties related to unrecognized tax benefits as a component of our income tax provision. We had accrued interest and penalties totaling $16.2 million and $20.0 million as of March 31, 2015 and December 31, 2014, respectively, that were included in other noncurrent liabilities in the Condensed Consolidated Balance Sheets.
Based upon the information available as of March 31, 2015, we anticipate that the amount of uncertain tax positions will change in the next twelve months; however, the change cannot reasonably be estimated.
For the three months ended March 31, 2015, tax expense specific to the period included a benefit of $28.3 million, which is primarily related to the resolution of certain state tax matters, resulting in a benefit of $18.4 million, and a reduction in tax rate change for one of our equity method investments, resulting in a benefit of $9.7 million.
For the three months ended March 31, 2014, we recorded tax benefits specific to the period of $62.5 million, which primarily related to the intended sale of our distribution business in Argentina at that time. This business was subsequently sold in November 2014 and such benefit was realized.
