Costs Allocations Using Simplified Costing method Versus

Activity-Based Costing Method- 100 Points

Madera and Belaval Co.

Madera and Belaval, architects, have been using a simplified costing

system in which all professional labor costs are included in a single direct

cost category, professional labor; and all overhead costs are included in a

single indirect cost category, professional support, and allocated to jobs

by using professional labor hours as the allocation base. Consider two

clients:Don Pepess Restaurant, which required 27 hours of design work for a

new addition, and Mr. Carlos Pstor- C.P.A. , who required plans for a new ultramodern

home that took 39 hours to draw. The firm has two partners, who each

earn a salary of $140,000 a year, and four associates, who each earn

$65,000 per year. Each professional has 1,450 billable hours per year. The

professional support is $1,090,000, which consists of $710,000 of design

support and $360,000 of staff support. Don Pepes job required four hours of

partner time and 22 hours of associate time. Mr. Carlos Pstor, C.P.A. job required 20 hours

of partner time and 20 hours of associate time.

Required: Using the example of page 468 of the textbook do the following:

1. Prepare job cost sheets for Don Pepes Restaurant and Mr. Carlos Pstor, C.P,A, , using a

simplified costing system with one direct and one indirect cost pool.

2. Prepare job cost sheets for the two clients, using an activity-based

costing system with two direct cost categoriespartner labor and

associate laborand two indirect cost categoriesdesign support and

staff support. Use professional labor dollars as the cost allocation base

for design support and professional labor hours for staff support.

(Round rates to two decimal places.)

3. Determine the amount by which each job was under- or - overcosted,

using the simplified costing system.
