Answer:
$146,601,502.64
Step-by-step explanation:
Preparation of the present value of this liability
Using this formula
PV = FV / (1 +r)t
Where,
FV=$578,000,000
r=(1+0.071)=(1.071)
t=20 years
Let plug in the formula
PV = $578,000,000 / (1+0.071)^20
PV = $578,000,000 / (1.071)^20
PV = $578,000,000 / 3.942660815715
PV = $146,601,502.64
Therefore the present value of this liability will be $146,601,502.64
