Final answer:
Interest on a loan taken to finance Evershine Corporation's new project should be excluded from the cash flow calculations for NPV because it is a financing cost not directly related to the operations of the project.
Step-by-step explanation:
When Evershine Corporation is evaluating the project to manufacture high-tech printers and calculating the Net Present Value (NPV), certain items should not be included in the cash flow calculations. Among the choices provided, interest on a loan which was taken to finance the new project should be excluded.
This is because interest is a financing cost and NPV calculations are concerned solely with operational cash flows that affect the firm's valuation. NPV focuses on revenues and costs that are directly related to the project's operations such as increased or decreased sales, changes in working capital like accounts receivable or inventory levels, and the use of existing assets like a building.
