Brief Exercise 155 Colby Company estimates that annual manufacturing overhead costs will be $600,000. Estimated annual operating activity bases are: direct labor cost $460,000, direct labor hours 40,000 and machine hours 80,000. The actual manufacturing overhead cost for the year was $601,000 and the actual direct labor cost for the year was $456,000. Actual direct labor hours totaled 39,800 and machine hours totaled 79,000. Colby applies overhead based on direct labor hours.
