Note: Indicate the effect of the first three variance by selecting "Favorable" or "Unfavorable". Select "None" and enter "O" for no effect (ie., zero variance). Select "Positive" or "Negative" for the Fixed-overhead Volume variance. 1. Variable-overhead spending variance 2. Variable-overhead efficiency variance 3. Fixed-overhead budget variance 4. Fixed-overhead volume variance Favorable Unfavorable None
