Overhead Variances, Four-Varlance Analysis Oerstman, Inc., uses a standard costing system and develops its overhead rates from the current annual budget. The budget is based on an expected annual output of 121,000 units requiring 484,000 direct labor hours. (Practical capacity is 504,000 hours.) Annual budpeted overhead costs total $793,760, of which $571,120 is fixed overhead. A total of 119,500 units using 482,000 direct labor hoirs were produced during the year. Actual variable overhead costs for the vear were $261,400, and actual fixed overhead costs were $555,550. Required: 1. Compute the fixed overhead spending and volume variances. 2. Compute the variable overhead spending and effiency variances. Do not round intermediate calculations Varlable Overhead Spending Varlance Variable Overhead Efficiency Variance
