The above table shows the present value of the total vested pension benefits
over the period 2017–2021. At the end of each year, the total vested pension
for the discount period mentioned in column (6) using a discount rate of 10%.
Based on this information, the pension expense is calculated as follows:

in the present value of the total vested pension benefit. The service cost is

Requirement 2:
In this case, the pension expense will exactly equal the service cost:

Total $52 ,453 $12 ,547 $(12 ,547) $52 ,453

Requirement 3:
Under the unfunded scenario, the pension expense is the sum of the service
earn by investing the service cost in an investment that offers an annual rate of
return of 10%?

Consequently, in the unfunded case, if the company had invested the service
cash saved from not funding the pension plan. This will be compensated by the
higher pension expense.

The following observations emerge from this comparison:
(1) Over the life of a company, the total pension expense is the same
(2) However, the service cost is lower when the discount rate is higher,
(3) Since interest cost represents the time value of money, more of the interest
rates are lower.
