Students should work in teams of up to 3 members (It is recommended that teams are formed based on IP groups). Students should not discuss the case with anyone except their teammates. Students should not circulate the case on the internet. The solution to all questions must be typed and handed to me in class on the date due which is Thursday, April 21. Each member of the team should be listed alphabetically on the submission. Calculations should be rounded off to two decimal places if necessary.

Murphy Inc. manufactures a single product, DLZ. Murphy uses budgets and standards in its planning and control functions. Murphy makes use of its standards in order to derive their budgeted cost per unit. For example, Exhibit A provides information on the budgeted variable costs per unit. When determining direct material costs for the planning budget income statement, the $10 budgeted material cost per unit of DLZ would be used in the calculation.

Raw material: 2 pounds at $5 per pound                                                          $10

Direct labor: 0.5 direct labor hour at $12 per hour                                             6

Variable overhead: 0.5 direct labor hour at $8 per hour                                     4

 Total variable budgeted (standard) cost per DLZ                                            $20

The standards for fixed manufacturing overhead costs are: 0.5 direct labor hour at $30 per hour. The standard fixed manufacturing overhead cost per hour is calculated based on a denominator level of activity of 50,000 direct labor hours.

The planning budget income statement is based on the expectation of selling 100,000 units of DLZ. The budgeted sales price is $60 per unit, and total budgeted fixed selling and administrative costs are $1,800,000. There are no variable selling and administrative costs in this firm.

The company actually produced and sold 120,000 units this year. The company never has a beginning or ending raw materials inventory, because it uses all raw materials purchased. Also, the company never has a beginning or ending finished goods inventory. Everything produced in the year is sold in that same year.

Required:

1. Could you explain to your boss why the company should use the flexible budget income statement in the variance analysis?

2. Prepare a detailed income statement variance analysis using the contribution approach income statement (i.e., variable costing basis) for the year (i.e., compare the actual income statement with the flexible budget income statement and compare the flexible budget income statement with the planning budget income statement). Show all the revenue, spending, and activity variances appearing in the income statement analysis. A template for answering this question is given below. All variances should be marked with either an “F” for favorable or “U” for unfavorable.

3. Prepare a very detailed manufacturing cost variance analysis (e.g., calculate the material price variance and quantity variance; the labor rate variance and efficiency variance; the variable overhead rate variance and efficiency variance; and the fixed manufacturing overhead budget variance and volume variance). All variances should be marked with either an “F” for favorable or “U” for unfavorable.

4. Could you reconcile spending variances in Part 2 with manufacturing cost variances in Part 3? In other words, for each category of manufacturing costs, show the relationship between the variances in Part 2 with those in Part 3.
