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.

These costs are based on a normal operating range of 14, 100 to 28, 200 machine-hours per month: During March, the first month after your preparation of the above data, the Machining Department worked 26, 100 machine-hours and produced 13, 050 units of product. The actual manufacturing overhead costs for March were as follows: Fixed costs had no budget variances. The department had originally been budgeted to work 28, 200 machine-hours during March. Required 1. Prepare an overhead performance report for the Machining Department for the month of March.
