In our U.S. plans, improvement through December 2010 in the valuation of pension investments increased our 2011 expected return on plan assets, and longer amortization periods decreased our 2011 net amortization and deferral costs. The longer amortization periods were due to all participants in certain U.S. plans being inactive and to changes in the pattern of retirements. In our non-U.S. plans, various curtailments and settlements recorded in 2010 decreased our benefit obligations and plan assets, which in turn reduced our 2011 interest cost and expected return on plan assets. In the third quarter of 2010, we recognized $0.7 million of prior service cost amortization related to a temporary change in our postretirement health care benefit plan and a $0.2 million curtailment gain related to our restructuring activities in the Netherlands. In the second quarter of 2010, we recognized $4.0 million of curtailment and settlement gains related to our restructuring activities in the Netherlands and France and a $0.2 million settlement loss related to the transfer of some pension obligations to another company in Germany. In the first quarter of 2010, we recognized a $0.7 million gain from the settlement of certain pension obligations in Japan.
