Kenseth Corp. has the following beginning-of-the-year present values for its projected benefit obligation and market-related values for its pension plan assets. Projected benefit obligation Plan Assets Value
2011 $2,000,000 $1,900,000
2012 2,400,000 2,500,000
2013 2,950,000 2,600,000
2014 3,600,000 3,000,000
The average remaining service life per employee in 2011 and 2012 is 10 years and in 2013 and 2014 is 12 years. The net gain or loss that occurred during each year is as follows: 2011, $280,000 loss; 2012, $90,000 loss; 2013, $11,000 loss; and 2014, $25,000 gain. (In working the solution, the gains and losses must be aggregated to arrive at year-end balances.)

Calculation for the net gain or loss amortized and charged to pension expense under the corridor approach

Year, Projected Benefit Obligation (a) , Plan Assets, 10%Corridor, Accumulated d OCI (G/L) (a), Minimum Amortization of Loss

2011 $2,000,000 $1,900,000 $200,000 $ 0 $0

Calculation for 10%Corridor

2011 $0

2012 10%*$2,500,000 =$250,000

2013 10%*$2,950,000 =$295,000

2014 10%*$3,600,000 =$360,000

Calculation for Accumulated Depreciation and Minimum Amortization of Loss

a. As at the beginning of the year

b. ($280,000 – $250,000) ÷ 10 years = $3,000

c. $280,000 – $3,000 + $90,000 = $367,000

d. ($367,000 – $295,000) ÷ 12 years = $6,000

e. $367,000 – $6,000 + $11,000 = $372,000

f ($372,000 – $360,000) ÷ 12 years = $1,000

Therefore the net gain or loss amortized and charged to pension expense under the corridor approach are :
