Question 1
According to Exhibit 2, Model Year Budgets for the ACF, we can know the total overhead, and direct labor costs. Therefore, we can calculate the budget of overhead allocation rate. | Total Overhead | Direct Labor Costs | Overhead/ Direct Labor Costs | 1987 | $107,954 | $24,682 | 437% |
However, according to the question 1, the overhead allocation rate used in the 1987 model-year strategy study at the ACF was 435%. The two numbers are different because 435% is the actual number, and 437% which is from the budget is estimated rate.
Question 2 | Total OH | DLC | DMC | Sales | OH/DLC | OH/DMC | OH/Sales | 1987 | $107,954 | $24,682 | $122,365 | $330,154 | 437.3794668 | 88.22293957 | 32.69807423 | 1988 | $109,890 | $25,294 | $127,363 | $351,071 | 434.4508579 | 86.28094502 | 31.30136069 | 1989 | $78,157 | $13,537 | $66,956 | $216,338 | 577.3583512 | 116.7288966 | 36.12726382 | 1990 | $79,393 | $14,102 | $69,546 | $226,542 | 562.9910651 | 114.1589739 | 35.04559861 |
The changes in overhead allocation rates from 1988 to 1990 are very significant while we compare to 1987 rates. The reason these changes have occurred can be seen below. Essentially, between 1988 and 1989 total overhead costs decreased at a slower pace than direct labor costs, direct material costs, and sales.
