Mackmyra Whisky AB needs additional funds for further expansion. The problem with their business of producing and selling whisky is a long cash conversion cycle, which means that cash comes in only 9, 12 or 15 years after production due to the long storage time of the whisky in oak barrels.

Mackmyra AB considers to take a loan of 30 million SEK for the expansion at a borrowing rate of 3%. However, Mackmyra's new CFO, a former JIBS student, proposes to sell 30-liter whisky barrels in advance to customers right after production. (Customers would take care themselves regarding the storage of their whisky barrels for some years until the whisky is bottlened and ready for consumption.) However, the price of a freshly distilled whisky barrel (called a zero-year barrel) is lower than those of 9, 12 or 15 years old barrels. The CFO estimates that Mackmyra could sell the zero-year barrel at a price of 17750 kr. Currently, 9-year barrels are sold at a price of 25000 kr, 12-year barrels are sold at a price of 28500 kr and 15-year barrels are sold at a price of 31000 kr. (For the sake of simplicity, we assume that there won't be price changes for the barrels in the coming years.)

a.) Calculate the NPV of this proposal. Assumption: From three produced whisky barrels, one is sold as 9-year, one is sold as 12-year, and the third one is sold as a 15-year barrel.

(Hint: assume that selling three zero-year barrels implies to loose the income from selling them as 9-, 12-, and 15-year barrel later on.)

b.) At which price of the zero-year barrel is Mackmyra indifferent between taking a loan or selling the zero-year barrels? (or to put it differently, at which price of the zero-year barrel do we have a break-even?)

c.) Consider now the perspective of an investor who is interested to buy zero-year barrels at a price of 17750 kr. What is the IRR of buying three zero-year barrels and keeping them until 9, 12 and 15 years respectively, and to sell them in those years at the prices stated above? (We assume again that prices do not change and that the investor has no storage costs.)

d) If the investor has an opportunity cost of capital of 3%, should she buy the zero-year barrel at a price of 17750 kr?

A plane delivers two types of cargo between two destinations. Each crate of cargo I is 7 cubic feet in volume and 131 pounds in weight, and earns $20 in revenue. Each crate of cargo II is 7 cubic feet in volume and 262 pounds in weight, and earns $25 in revenue. The plane has available at most 525 cubic feet and 12,576 pounds for the crates. Finally, at least twice the number of crates of I as II must be shipped. Find the number of crates of each cargo to ship in order to maximize revenue. Find the maximum revenue.

2. National Business Machines manufactures x model A fax machines and y model B fax machines. Each model A costs $100 to make, and each model B costs $150. The profits are $45 for each model A and $30 for each model B fax machine. If the total number of fax machines demanded per month does not exceed 2500 and the company has earmarked no more than $600,000/month for manufacturing costs, how many units of each model should National make each month to maximize its monthly profit?
