Final answer:
The fixed overhead cost variance can be further subdivided into the flexible-budget variance and the production-volume variance.
Step-by-step explanation:
The fixed overhead cost variance can be further subdivided into the flexible-budget variance and the production-volume variance. These variances help analyze the differences between the planned and actual fixed overhead costs. The flexible-budget variance measures the difference between the budgeted fixed overheads and the actual fixed overheads based on the flexible budget, while the production-volume variance measures the effect of changes in the production level on fixed overhead costs.
