In February 2013, the Compensation and Human Resource Committee of NCR's Board of Directors approved the termination of NCR's U.S. non-qualified pension plans, resulting in a curtailment of those plans. As a result, during the three and six months ended June 30, 2013, an actuarial gain of $5 million and $15 million, respectively, was recognized associated with the termination of NCR's U.S. non-qualified pension plans.

During the first quarter of 2013, a select group of U.S. employees were offered the option to participate in a voluntary early retirement opportunity, which included incremental benefits for each employee who elected to participate.
