We amended and curtailed our retiree health care benefit plan in the second quarter of 2012, which resulted in a non-cash gain of $45.0 million primarily as a result of reversals of accrued liabilities and the related balance in "Accumulated Other Comprehensive Income", ("AOCI"), related to these terminated benefits. Due to the negative plan amendment, we recorded and will continue to record increased amortization of net gains until December 31, 2013.
Based on a detailed review of the provisions of our defined benefit plan in India in the fourth quarter of 2012, we reclassified this plan from other postretirement benefit plans to pension benefit plans. We have reclassified the disclosures in the above tables for the three and six months ended June 30, 2012, to conform to classifications used at June 30, 2013. The total net periodic expense reclassified from other postretirement benefit plans to pension benefit plans was $0.1 million and $0.3 million for the three and six months ended June 30, 2012, respectively. This reclassification had no impact on our Consolidated Balance Sheets or Consolidated Statements of Operations.
We have a defined contribution retirement plan that covers substantially all domestic employees. The expense for this plan was $0.5 million for each of the three months ended June 30, 2013 and 2012, and $1.3 million and $1.5 million for the six months ended June 30, 2013 and 2012, respectively. All contributions were funded from the proceeds obtained from the reversion of our former salaried pension plan.
