The condensed form of Nordstrop Companys flexible budget for manufacturing overhead follows:

	Cost Formula			Machine-Hours
Overhead Costs	(per machine-hour)			8,000		9,000		10,000
Variable cost	$	1.65		$	13,200	$	14,850	$	16,500
Fixed cost					20,800		20,800		20,800
Total overhead cost				$	34,000	$	35,650	$	37,300

The following information is available for a recent period:

1. The denominator activity of 8,000 machine-hours was chosen to compute the predetermined overhead rate.
2. At the 8,000 standard machine-hours level of activity, the company should produce 1,600 units of product.
3. The companys actual operating results were as follows:

Number of units produced		1,900
Actual machine-hours		9,000
Actual variable overhead costs	$	13,680
Actual fixed overhead costs	$	25,000

3. Compute the variable overhead spending and efficiency variances and the fixed overhead budget and volume variances. (Do not round intermediate calculations. Round your answers to 2 decimal places. Indicate the effect of each variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance).)
