Answer:
$334,680
Step-by-step explanation:
The computation of amount of the PBO is shown below:-
Interest cost = Beginning balance of PBO × Discount rate in percentage
= $271,000 × 8%
= $21,680
Closing PBO = Beginning balance of PBO + Service cost + Interest cost - Benefit paid
= $271,000 + $85,000 + $21,680 - $43,000
= $377,680 - $43,000
= $334,680
