(b) Based on the revised assumptions at the end of the year, determine what percentage increase or decrease there would be in the ABO for:
1. a 1% increase in the discount rate.
2. a 1% decrease in the discount rate.
(c) Determine the effect of the actuarial revaluation on the plan’s funded status at December 31, 2010, and on pension expense for 2010 and for 2011.
