Answer:
$336,800
Step-by-step explanation:
Computation of the given data are as follows:
PBO on Jan 1,2021 = $268,000
Service cost = $87,000
Rate = 10%
Interest Amount = ($268,000 × 10%) = $26,800
Pension benefits paid = $45,000
So, PBO at Dec 31,2021 = PBO on Jan 1,2021 + Service cost + Interest Amount - Pension benefits paid
= $268,000 + $87,000 + $26,800 - $45,000
= $336,800
