Problem 5-45 Volume-Based Costing versus ABC [LO 5-1, 5-3, 5-5]
[The following information applies to the questions displayed below.]
ADA Pharmaceutical Company produces three drugs—Diomycin, Homycin, and Addolin—belonging to the analgesic (pain-killer) family of medication. Since its inception four years ago, ADA has used a direct labor hour–based system to assign manufacturing overhead costs to products.
Eme Weissman, the president of ADA Pharmaceutical, has just read about activity-based costing in a trade journal. With some curiosity and interest, she asked her financial controller, Takedo Simon, to examine differences in product costs between the firm’s current costing and activity-based costing systems.
ADA has the following budget information for the year:
| Diomycin | Homycin | Addolin | |||||||||
| Cost of direct materials | $ | 210,000 | $ | 270,000 | $ | 263,000 | |||||
| Cost of direct labor | 255,000 | 239,000 | 268,000 | ||||||||
| Number of direct labor hours | 7,250 | 6,850 | 2,050 | ||||||||
| Number of capsules | 1,050,000 | 505,000 | 305,000 | ||||||||
ADA has identified the following activities and cost drivers and has assigned them a total overhead cost of $202,500.
| Activity | Cost Driver | Budgeted Overhead Cost | Budgeted Cost Driver Volume | |||||
| Machine setup | Setup hours | $ | 16,500 | 1,650 | ||||
| Plant management | Number of Workers | 36,500 | 1,250 | |||||
| Supervision of direct labor | Direct labor hours | 46,500 | 16,500 | |||||
| Quality inspection | Inspection hours | 50,900 | 1,075 | |||||
| Order expediting | Customers served | 52,100 | 670 | |||||
| Total overhead | $ | 202,500 | ||||||
Takedo selected the cost drivers with the following justifications:
SETUP HOURS: The cost driver of setup hours is used because the same product takes about the same amount of setup time regardless of size of batch. For different products, however, the setup time varies.
NUMBER OF WORKERS: Plant management includes plant maintenance and corresponding managerial duties that make production possible. This activity depends on the number of workers. The more workers involved, the higher the cost.
DIRECT LABOR HOURS: Supervisors spend their time supervising production. The amount of time they spend on each product is proportional to the direct labor hours worked.
INSPECTION HOURS: Inspection involves testing a number of units in a batch. The time varies for different products but is the same for all similar products.
NUMBER OF CUSTOMERS SERVED: The need to expedite production increases as the number of customers served by the company increases. Thus, the number of customers served by ADA is a good measure of expediting production orders.
Takedo gathered the following information about the cost driver volume for each product:
| Diomycin | Homycin | Addolin | |||||||||
| Setup hours | 225 | 625 | 825 | ||||||||
| Number of workers | 225 | 425 | 625 | ||||||||
| Direct labor hours | 7,250 | 6,850 | 2,050 | ||||||||
| Inspection hours | 175 | 225 | 725 | ||||||||
| Customers served | 50 | 105 | 525 | ||||||||
Use the activity-based cost system to calculate the unit cost of each product. (Round intermediate calculations to 2 decimal places. Round "Cost per capsule" to 2 decimal places.)
|
Part 1
Required:
1. Use the firm’s current costing system to calculate the unit cost of each product.
2. Use the activity-based cost system to calculate the unit cost of each product.

It is known that the mean time to solve the puzzle in healthy control children is 60 seconds. Carry out the Wilcoxon signed-rank test on these data to test the null hypothesis that the mean time to solve the puzzle for children with NF1 is the same as for healthy controls.
a) Calculate the value of the test statistic and give the approximate normal distribution of the test statistic under the null hypothesis.
b) Calculate the p-value for the test assuming a two-sided alternative hypothesis.
c) What do you conclude about the time taken by children with NF1 to solve the puzzle compared to healthy controls?
d) Describe in a few sentences how you would calculate a 95% confidence interval for the mean time without assuming any particular parametric model for the data. You do not need to calculate the interval.

Case description: Credit and charge card issuer American Express (Amex) had developed a strong reputation among consumers due in part to its Membership Rewards (MR) loyalty program, first established in 1991. Through MR, all Amex cardholders could accumulate and redeem "points" based on how much they spent, while customers with Amex's Gold and Platinum Cards received additional perks. By 2016, however, the U.S. credit card market had become increasingly competitive, with many credit card companies increasing their sign-on point bonuses for new customers. Chris Cracchiolo, Amex's vice president of U.S. loyalty, strategy, and global partnerships, had to decide how to position the MR program in the face of this competition. Should Amex begin offering more competitive sign-on bonuses and point redemption rates, or would this dilute the company's strong brand?
Discussion Question: List and discuss three factors that companies, including American Express, should take into account in designing loyalty programs aimed at attracting and retaining clients. Write at least 3-4 sentences about each factor.

5.1. The sales director of New World Limited has drafted a scheme to increase sales by relaxing credit limits imposed on customers. Sales invoices, at present payable after a one-month credit period, should henceforward be payable after two months. Currently, sales are steady at R500 000 per month, earning a gross profit margin of 18%. If two months’ credit is allowed, sales would increase to R620 000 per month. An extra clerk to account for the new customers will be employed at R15 000 per annum. The finance director fears that extending sales credit will increase the bad debts suffered from 1% of sales to 2% of sales. He is also concerned about the overdraft limit, but the bank manager is very supportive of the scheme, offering extended overdraft facilities at 14% per annum. Evaluate the sales director’s scheme. Also factor in the cost of carrying the debtors as part of your calculation. Perform these calculations based on yearly figures. (12)
