Sydney Harbour Fuel has decided to shift from supply of petrol and light diesel fuel to sale of heavy diesel fuel. To do so, they need to purchase 8 new barges at a cost of $4 Mn each. The computation of incremental net cash flow and the net present value of the incremental cash flow is used to make the decision. The net present value of the incremental cash flows is $187 Mn, which implies that the company would be able to generate an additional amount of $187 Mn, as compared to the present scenario.
