Chapter 5, Problem 33P
Dr. Alyx Hemmings is employed by Mesa Dental. Mesa Dental recently installed a computerized job-order costing system to help monitor the cost of its services. Each patient is assigned a job number when he or she checks in with the receptionist. The receptionist-bookkeeper notes the time the patient enters the treatment area and when the patient leaves the area. This difference between the entry and exit times is the number of patient hours used and the direct labor time assigned to the dental assistant. (A dental assistant is constantly with the patient.) The direct labor time assigned to the dentist is 50 percent of the patient hours. (The dentist typically splits her time between two patients.)
The chart filled out by the dental assistant provides additional data that is entered into the computer. For example, the chart contains service codes that identify the nature of the treatment, such as whether the patient received a crown, a filling, or a root canal. The chart not only identifies the type of service but its level as well. For example, if a patient receives a filling, the dental assistant indicates (by a service-level code) whether the filling was one, two, three, or four surfaces. The service and service-level codes are used to determine the rate to be charged to the patient. The costs of providing different services and their levels also vary.
Costs assignable to a patient consist of materials, labor, and
The overhead rate does not include a charge for any X-rays. The X-Ray Department is separate from dental services; X-rays are billed and costed separately. The cost of an X-ray is $12 per film; the patient is charged $15 per film. If cleaning services are required, cleaning labor costs $35 per patient hour.
Glen Johnson, a patient (Job 267), spent 30 minutes in the treatment area and had a two-surface filling. He received two Novocaine shots and used three ampules of amalgam. The cost of the shots was $14 ($7 each). The cost of the amalgam was $6 per ampule. Other direct materials used are insignificant in amount and are included in the overhead rate. The rate charged to the patient for a two-surface filling is $110. One X-ray was taken.
Required:
- 1. Prepare a
job-order cost sheet for Glen Johnson. What is the cost for providing a two-surface filling? What is the gross profit earned? Is the X-ray a direct cost of the service? Why are the X-rays costed separately from the overhead cost assignment? - 2. Suppose that the patient time and associated patient charges are given for the following fillings:
Compute the cost for each filling and the gross profit for each type of filling. Assume that the cost of Novocaine is $14 for all fillings. Ampules of amalgam start at two and increase by one for each additional surface. Assume also that only one X-ray film is needed for all four cases. Does the increase in billing rate appear to be fair to the patient? Is it fair to the dental corporation?

The Tennis Club Company makes custom tennis rackets. The manufacturing supervisor interviews people who have specialized manufacturing skills for recruitment, and he informs payroll when an employee is hired. The employees punch a card to a time clock to record the hours they work. The employees are also required to keep a record of the time they spend working on each order. The supervisor approves all time cards.
The accountant analyzes the job tickets and prepares a labor distribution summary. Payroll prepares the payroll register and paychecks. The supervisor distributes the paychecks to the employees. Payroll informs cash disbursement of the funds required to cover the entire payroll amount. The cash disbursements clerk ensures that there are adequate funds in the company's regular checking account to cover the payroll.
Required:
1. Identify and discuss three internal control weaknesses.
2. Suggest an improvement to internal control for each weakness.
In job-order costing, all of the following statements are correct with respect to labor time and cost except:
Multiple Choice
time tickets are kept by employees showing the amount of work on specific jobs.
the job cost sheet for a job will contain all direct labor charges to that particular job.
labor cost that can be traced to a job only with a great deal of effort is treated as part of manufacturing overhead.
a machine operator performing routine annual maintenance work on a piece of equipment would charge the maintenance time to a specific
job.

- Hampton Court Furniture Company refinishes and reupholsters furniture. Hampton uses a job order cost system. When a prospective customer asks for a price quote on a job, the estimated cost data are inserted on an unnumbered job cost sheet. If the offer is accepted, a number is assigned to the job, and the costs incurred are recorded in the usual manner on the job cost sheet. After the job is completed, reasons for the variances between the estimated and actual costs are noted on the sheet. The data are then available to management in evaluating the efficiency of operations and in preparing quotes on future jobs. On June 10, 2006, an estimate of $561.60 for reupholstering a chair and couch was given to Danzel Bishop.

Darnell pays his workers a salary; during busy times, everyone works to get the orders out. Temps (temporary workers hired through an agency) may be hired to pack and prepare completed orders for shipment. During slower times, Darnell catches up on bookkeeping and administrative tasks while the salaried workers do preventive maintenance, clean the lines and building, etc. Temps are not hired during slow times. Darnell found that workers salaries, temp agency payments, rentals, utilities, and plant and equipment depreciation are the largest dollar accounts. He believes that workers salaries and plant and equipment depreciation are fixed, temp agency payments are associated with the number of orders (since temp workers are used to pack and prepare completed orders for shipment), and electricity is associated with the number of machine hours. When the number of different parts stored by Poston exceeds the space in the materials storeroom, Darnell rents nearby warehouse space. He can rent as much or as little space as he wants on a month-to-month basis. Therefore, he believes warehouse rental payments are variable with the number of parts purchased and stored. The account balances for the past six months as well as the six-month total are as follows: Information on number of machine hours, orders, and parts for the six-month period follows: Required: 1. Calculate the monthly average account balance for each account. Calculate the average monthly amount for each of the three drivers. 2. Calculate fixed monthly cost and the variable rates for temp agency payments, warehouse rent, and electricity. Express the results in the form of an equation for total cost. 3. In July, Darnell predicts there will be 420 orders, 250 parts, and 5,900 machine hours. What is the total labor and overhead cost for July? 4. What if Darnell buys a new machine in July for 24,000? The machine is expected to last 10 years and will have no salvage value at the end of that time. What part of the cost equation will be affected? How? What is the new expected cost in July?arrow_forwardThe following describes the job responsibilities of two employees of Barney Manufacturing. Joan Dennison, Cost Accounting Manager.
