Musk oil has become so popular as a perfume base that it has become necessary to carry large inventories as a precaution against stock depletion. For this reason, the inventory of musk oil at the end of a quarter must be equal to 20% of the following quarter's production needs. Some 36,000 grams of musk oil will be on hand to start the first quarter of year 2.
