During the fourth quarter of 2013, management approved changes to certain of our defined benefit pension and postretirement plans, including the merging of plans and the elimination of future benefit accruals for plan participants as of December 31, 2013. During the three months ended March 31, 2014 and 2013, we made contributions to our global postretirement plans of $2.1 and $2.6, respectively. We do not expect to make material contributions to our global pension plans during the remainder of 2014. During the three months ended March 31, 2014 and 2013, we amortized $0.6 and $3.8, net of tax, respectively, from accumulated other comprehensive income into earnings related to prior service cost and net actuarial loss. No other reclassifications from accumulated other comprehensive income into earnings were recognized during the presented periods.
