As a special advisor to Special Road Infrastructure Development, you have been approached by the Minister to evaluate the financial viability of three alternative road improvement projects. Project data are captured in Table 3.1:

Using Net Present Value analysis, determine which of the project alternatives is worth implementation.
(Hint: F = P ( 1+i )n ; P = A [ (1+i)n – 1] / [ i * (1+i)n])
F = P ( 1+i )n ; PVAF = A [ (1+i)n – 1] / [ i * (1+i)n]; PVIF = 1 / (1 + i)n
Net Present Valye = Present value of cash inflow - Present value of cash outflows
PVAF(18/0.125)=1(1−(1+0.125)^−18/ 0.125)
=1(1−0.120020269037840.125)
=1(7.0398378476973)
=7.0398378476973
PVAF(12/0.125)=1(1−(1+0.125)^−12/ 0.125)
=1(1−0.24331547469230.125)
=1(6.0534762024616)
=6.0534762024616
PVAF(30/0.125)=1(1−(1+0.125)^−30/ 0.125)
=1(1−0.0292027887336390.125)
=1(7.7663776901309)
=7.7663776901309
PVIF(18/0.125) = 1/(1+0.125)^18 = 0.1200
PVIF(30/0.125) = 1/(1+0.125)^30 = 0.0292
Alternative A:
Cash outflow = P.V. of initial cost + P.V. of annual maintenance cost + P.V. annual energy cost - P.V. of salvage value
= 7,500,000 + 200,000*PVAF(12.5%, 18) +
250,000*PVAF(12.5%,12)*PVIF(12.5%,18)
+ 200,000*PVAF(12.5%,30) - 950,000*PVIF(12.5%,30)
= 7,500,000 + 200,000*7.0398 + 250,000*6.0535*0.1200 +
200,000*7.7664 - 950,000*0.0292
= 7,500,000 + 1,407,960 + 181,605 +1,553,280 - 27,740
= 10,615,105
Cash inflow = P.V. of annual revenue
= 350,000*PVAF(12.5%,30)
= 350,000*7.7664
= 2,718,240
NPV = 2,718,240 - 10,615,105 = -7,896,865
Alternative B:
Cash outflow = P.V. of initial cost + P.V. of annual maintenance cost + P.V. annual energy cost - P.V. of salvage value
= 8,500,000 + 190,000*PVAF(12.5%, 20) +
220,000*PVAF(12.5%,15)*PVIF(12.5%,20)
+ 180,000*PVAF(12.5%,35) - 1,200,000*PVIF(12.5%,35)
= 8,500,000 + 190,000*7.2413 + 220,000*6.6328*0.0948
+ 180,000*7.8703 - 1,200,000*0.0162
= 8,500,000 + 1,375,847 + 138,334 + 1,416,654 - 20,160
= 11,410,675
Cash inflow = P.V. of annual revenue
= 450,000*PVAF(12.5%,35)
= 450,000*7.8703
= 3,541,635
NPV = 3,541,635 - 11,410,675 = -7,869,040
Alternative C:
Cash outflow = P.V. of initial cost + P.V. of annual maintenance cost + P.V. annual energy cost - P.V. of salvage value
= 9,500,000 + 170,000*PVAF(12.5%, 30) +
190,000*PVAF(12.5%,10)*PVIF(12.5%,30)
+ 180,000*PVAF(12.5%,40) - 1,400,000*PVIF(12.5%,40)
= 9,500,000 + 170,000*7.7664+
190,000*5.5364*0.0292
+ 180,000*7.9280- 1,400,000*0.0090
= 9,500,000 + 1,320,288 + 30,716 + 1,403,640 - 12,600
= 12,242,044
Cash inflow = P.V. of annual revenue
= 600,000*PVAF(12.5%,40)
= 600,000*7.9280
= 4,756,800
NPV = 4,756,800 - 12,242,044 = -7,485,244
Since the NPV is maxium for Alternative C among all three alternative available, the company should implement alternative C.
Although, none of the NPV is positive, we are considering the highest among the three.
