At a discount rate of 10%, the Net Present Value (NPV) is given as
NPV
|
$26,116,989,970.34
|
While the is

IRR
|
23419.58%
|
3. At 6% the NPV is $36,796,298,366.68, this value is greater than 0 hence the project is profitable.
On the other hand, at 12% the NPV is obtained as $22,455,372,302.21 which is also greater than 0. This means the project will be profitable will remain profitable when the rate of discount fluctuates between 6% and 12%
- Increase in the cost of capital decreases the NPV while a decrease increases the NPV. The initial capital outlay is negatively proportionate to the profitability of the project.
- In cases where the price of gasoline only increases by 1.2% NPV will drop to $25,966,112,240.31. This indicates a fall in the level of profitability by 0.5777%.
- The maximum number of ships that the firm will need from Saudi Arabia in a single year will be 7. A drop in the maximum number of ships available from Saudi Arabia from 20 to 14 still allows the firm to obtain 7 ships. This means there will be no impact on profitability as the firm will not need to review its crude oil supply structure.
- The increase in shipment cost from Austrlaia from $ 1.8 to $ 2.5 per barrel will increase the cost of purchases which in turn will leads to a drop in the profits of the refinery products.
