Problem 8-18A Comprehensive Variance Analysis [LO4, LO5, LO6]

Portland Company's Ironton Plant produces precast ingots for industrial use. Carlos Santiago, who was recently appointed general manager of the Ironton Plant, has just been handed the plants contribution format income statement for October. The statement is shown below:

	Budgeted		Actual
Sales (4,000 ingots)	$	210,000	$	210,000
Variable expenses:
Variable cost of goods sold*		50,680		63,710
Variable selling expenses		12,000		12,000
Total variable expenses		62,680		75,710
Contribution margin		147,320		134,290
Fixed expenses:
Manufacturing overhead		61,000		61,000
Selling and administrative		76,000		76,000
Total fixed expenses		137,000		137,000
Net operating income (loss)	$	10,320	$	(2,710)

*Contains direct materials, direct labor, and variable manufacturing overhead.

Mr. Santiago was shocked to see the loss for the month, particularly because sales were exactly as budgeted. He stated, "I sure hope the plant has a standard cost system in operation. If it doesn't, I won't have the slightest idea of where to start looking for the problem."

The plant does use a standard cost system, with the following standard variable cost per ingot:

	Standard Quantity or Hours	Standard Price or Rate		Standard Cost
Direct materials	3.7 pounds	$	2.10 per pound	$	7.77
Direct labor	0.6 hours	$	6.70 per hour		4.02
Variable manufacturing overhead	0.4 hours*	$	2.20 per hour		0.88
Total standard variable cost				$	12.67

*Based on machine-hours.

During October the plant produced 4,000 ingots and incurred the following costs:

a.	Purchased 19,800 pounds of materials at a cost of $2.55 per pound. There were no raw materials in inventory at the beginning of the month.
b.	Used 14,600 pounds of materials in production. (Finished goods and work in process inventories are insignificant and can be ignored.)
c.	Worked 3,000 direct labor-hours at a cost of $6.40 per hour.
d.	Incurred total variable manufacturing overhead cost of $4,940 for the month. A total of 1,900 machine-hours was recorded.

It is the companys policy to close all variances to cost of goods sold on a monthly basis.

Required:

1.	Compute the following variances for October:

a.	Direct materials price and quantity variances. (Input all amounts as positive values. Leave no cells blank - be certain to enter "0" wherever required. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance.)

b.	Direct labor rate and efficiency variances. (Input all amounts as positive values. Leave no cells blank - be certain to enter "0" wherever required. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance.)

Labor efficiency variance	$	(Click to select)FNoneU

c.

Variable overhead rate and efficiency variances. (Input all amounts as positive values. Do not round your intermediate calculations. Leave no cells blank - be certain to enter "0" wherever required. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance.)

2a.

Summarize the variances that you computed in (1) above by showing the net overall favorable or unfavorable variance for October. (Input the amount as a positive value. Leave no cells blank - be certain to enter "0" wherever required. Indicate the effect of variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance.)
