Answer:
$159.59 million
Step-by-step explanation:
The present value of the liability is the future value of the obligation which in this case is $573 million discounted at the 6.6% appropriate discount chosen by the analyst as shown below:
PV=FV/(1+r)^n
PV=the present value of the obligation=the unknown
FV=$573 million
r=discount rate=6.6%
n=number of years before the liability becomes due=20
PV=$573 million/(1+6.6%)^20
PV=$573 million/1.066^20
PV=$573 million/3.590410405
PV=$159.59 million
