During the three months ended March 31, 2015 and 2014, we made contributions to our global postretirement plans of $2.6 and $2.1, respectively. We expect to make contributions of approximately $10 to $15 to our global postretirement plans during the remainder of 2015, principally related to other postretirement employee benefit plans.
During the three months ended March 31, 2015 and 2014, $0.5 and $0.6, net of tax, respectively, was amortized 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 any of the presented periods.
