Fixed assets will be depreciated using the straight-line method to reach zero at the end of the four-year period, at which point these assets will be worthless. The annual sales of this project are also estimated at 2,000,000 units annually Selling the unit is 2 riyals, and the variable cost of the unit is 1 riyal, and the fixed cost without property is $100,000. If the tax rate is 30%, what is the operating cash flow for the project? And if the project requires an initial investment in net working capital of $500,000 and the market value of the fixed assets will be $400,000 at the end of the project.
