Wallace Printing prints weekly advertisements for 15 customers. For 2016, Wallace budgeted $1,000,000 of manufacturing overhead cost and 20 million pages printed.
For 2016 Wallace Printing decided to evaluate the use of additional cost pools. After analyzing manufacturing overhead costs, it was determined that number of design changes, setups, and inspections are the primary manufacturing overhead cost drivers. The following information was gathered during the analysis:
Cost pool Manufacturing overhead costs Activity level
Design changes $360,000 300 design changes
Setups 600,000 4,000 setups
Inspections 40,000 1,000 inspections
Total overhead costs $1,000,000
During 2016, two of Wallace’s customers, Wealth Managers and Health Systems, used the following printing services:
Activity Wealth Managers Health Systems
Pages 100,000 125,000
Design changes 1 25
Setups 25 30
Inspections 4 15
Wallace Printing charges its customers $0.10 per page printed and uses normal costing. Total direct costs are $0.04 per page printed.
a. Suppose Wallace considers manufacturing overhead costs as one cost pool and allocates overhead based on the number of pages printed. What is the overhead allocation rate?
b. Using the allocation rate determined in the previous question, what is the manufacturing overhead cost allocated to Health Systems for 2016?
c. If Wallace considers manufacturing overhead costs as one cost pool and allocates overhead based on the number of pages printed, what profit (loss) does Wallace earn from Health Systems for 2016?
d. Now suppose Wallace uses activity cost pools. What is the allocation (activity) rate for the inspections cost pool?
e. If Wallace allocates manufacturing overhead costs using activity cost pools, what is the manufacturing overhead allocation for Wealth Managers during 2016?
f. If manufacturing overhead costs are allocated using activity cost pools, what profit (loss) does Wallace Printing earn from Wealth Managers during 2016?

Use the following information:
Today is June 8th
The company knows that it will need 20,000 barrels of jet oil oil at some time in October or November.
Heating oil futures contracts are currently traded for delivery every month on the exchange
Each contract size is 1,000 barrels.
Later, the company finds that it is ready to purchase the jet oil on October 10
Spot price (of jet fuel) and futures price (on heating oil) on Oct. 10 are $89.00 per barrel and $87.80 per barrel.
5. If no cross hedging was necessary (i.e. no asset mismatch, hence the optimal hedge ratio would be 1), assuming that there was a JET OIL FUTURES, what would have been the number of contracts to enter? And what would have been the effective price per barrel and the total effective price paid on Oct. 10?
6. If it was a perfect hedge (no timing mismatch or asset mismatch at all), what would have been the effective price per barrel and the total effective price?

1. You buy a 20-year bond with a coupon rate of 9.0% that has a yield to maturity of 10.1%. (Assume a face value of $1,000 and semiannual coupon payments.) Six months later, the yield to maturity is 11.1%. What is your return over the 6 months?
Rate of return:
2. Consider two 30-year maturity bonds. Bond A has a coupon rate of 4%, while bond B has a coupon rate of 12%. Both bonds pay their coupons semiannually.
a. Compute the prices of the two bonds at each interest rate. (Round the bond price to 2 decimal places.)
b. Suppose Bond A is currently priced to offer a yield to maturity of 8%. Calculate the (percentage) capital gain or loss on the bond if its yield immediately changes to each value of yield to maturity. (Enter your answers as a percent rounded to the nearest whole percent.)
c. Suppose Bond B is currently priced to offer a yield to maturity of 8%. Calculate the (percentage) capital gain or loss on the bond if its yield immediately changes to each value of yield to maturity. (Enter your answers as a percent rounded to the nearest whole percent.)
d. Which bond’s price exhibits greater proportional sensitivity to changes in its yield? In other words, which bond has greater interest rate risk?
e. Which bond pays a high coupon rate has lower “average” or “effective” maturity than a bond that pays a low coupon rate?
