Increase in Present Service Cost (PSC)-non-vested employees: $2,000
Remaiining vesting period- non-vested employees: 5 years
Remaining working life-vested employees 10 years
Remaining working life-non-vested employees: 20 years
Required:
a. Calculate the past service cost included in the 2013 net pension expense (or revenue) under U.S. GAAP.

Answer 1

Answer:

The past service cost included n the net pension is $600

Explanation:

Given Data;

Increase in present Service Cost (PSC)-vested employees = $5,000

Increase in present Service Cost (PSC)-non-vested employees= $2,000

Remaining vesting period- non-vested employees =5 years

Remaining working life-vested employees =10 years

Remaining working life-non-vested employees = 20 years

To calculate the past service cost in the net pension expense under U.S GAAP; we use the formula given as;

Past service cost =

$\frac{Increase PSC for vested employee}{Remaining working life of vested employees} + \frac {Increase PSC for non-vested employee}{remaining working life of non-vested employees}$

Substituting into the equation, we have;

Past service cost = $5,000/10 + $2,000/20

                            =$500 + $100

                           = $600

The past service cost included n the net pension is $600

Answer 2

Answer:

net pension expense (or revenue) under U.S.GAAP is $600

Explanation:

the past service cost included in the 2013 net pension expense ( or revenue) under U.S. GAAP is calculated below;

past service cost = { ( increase PSC for vested employees)

                             (remaining working life of vested employees)

                                                        +

                              {( increase PSC for non-vested employee)}

                               ( remaining working life of non- vested employees)

past service cost = { $5000/10years) + ( $ 2000/20years)

past service cost = $500 + $100

past service cost =$600

Therefore the past service cost  included in the 2013 net pension expense (or revenue) under U.S.GAAP is $600
