Final answer:
The answer calculates the NPV of Southern specialty products' current and revised manufacturing setups by assessing production costs, demand forecasts, and exchange rate fluctuations to determine the most cost-effective strategy.
Step-by-step explanation:
The Net Present Value (NPV) of total cost with the current manufacturing setup for Southern specialty products is calculated by considering the production and distribution costs from both Mississippi and Japan factories against the projected demand, exchange rates, and the probability of demand changes.
The NPV of the revised setup, which includes a capacity increase in the Mississippi plant, involves an additional fixed cost but possibly lower variable costs per unit due to increased production. The decision to increase capacity should be made by comparing the NPV of the current setup with the NPV of the revised setup and determining which provides a higher NPV at the 10% discount rate.
