Groschl Company has had great difficulty in controlling manufacturing overhead costs. At a recent convention, the president heard about a control device for overhead costs known as a flexible budget , and he has hired you to implement this budgeting program in Groschl Company. After some effort, you have developed the following cost formulas for the companys Machining Department. These costs are based on a normal operating range of 12,200 to 24,400 machine-hours per month:

Overhead Cost	Cost Formula
Utilities	$0.75 per machine-hour
Lubricants	$1.04 per machine-hour plus $11,300 per month
Machine setup	$0.41 per machine-hour
Indirect labour	$0.88 per machine-hour plus $148,000 per month
Depreciation	$49,500 per month

During March, the first month after your preparation of the above data, the Machining Department worked 20,400 machine-hours and produced 10,200 units of product. The actual manufacturing overhead costs for March were as follows:

Utilities	$	13,920
Lubricants		30,656
Machine setup		9,714
Indirect labour		168,092
Depreciation		49,500
Total manufacturing overhead cost	$	271,882

Fixed costs had no budget variances. The department had originally been budgeted to work 24,400 machine-hours during March.

Required:

1.	Prepare an overhead performance report for the Machining Department for the month of March.(Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Round "Cost Formula per MH" answers to 2 decimal places.)
