Answer:
Current year’s increase in the PBO that is associated to service is $14,752
Explanation:
Projected Benefit Obligation is the present value of retirement benefit that an employee gets.
PBO value at the end of the year = $309,796
PBO value at the beginning of the year = $278,343
Addition in PBO during the year = $309,796 - $278,343 = $31,453
Interest cost = $278,343*6% = $16,701
Addition associated with service = $31,453 - $16,701 = $14,752
