E20-8B (Application of the Corridor Approach) XTRA Inc. has beginning-of-the-year present values for its projected benefit obligation and market-related values for its pension plan assets.
2014 $1,000,000 $ 900,000
2015 1,250,000 1,100,000
2016 1,600,000 1,450,000
2017 2,100,000 2,000,000
The average remaining service-life per employee in 2014 and 2015 is 8 years and in 2016 and 2017 is 11 years. The net gain or loss that occurred during each year is as follows: 2014, $165,000 gain; 2015, $40,000 gain; 2016, $30,000 loss; and 2017, $15,000 loss. (In working the solution, the gains and losses must be aggregated
to arrive at year-end balances.)
Using the corridor approach, compute the amount of net gain or loss amortized and charged to pension expense in each of the 4 years, setting up an appropriate schedule.
