Dynamic Industrial is a relatively young company, with an unsophisticated accounting system. Dynamic Industrial manufactures two products, X370A, and Z410B. Each of the products has multiple components and materials (identified by SKU number), but assembly is relatively quick leaving no work in process inventory at the end of the period. Invoices are only approved for payment if the full quantity of the SKU has been received. 1) (80 points) Using the information provided, calculate the Materials Price Variance and Materials Efficiency Variance for each component/material. 2) (20 points) Dynamic Industrial purchasing manager has a friend who owns the company (COMP Inc) that produces some of the components that go into the X370A. COMP Inc. has been losing money in recent years. To save money, COMP Inc. has begun using a lower quality component and selling their components at a lower price to the public. However, the Dynamic Industrial's purchasing manager has not renegotiated the contract and continues to purchase the components at an above-market rate to help the friend. Is the purchasing manager's behavior in this situation ethical? Why or why not?
