Forestry Products Company uses a job-order costing system at its Woodton, New Brunswick, manufacturing plant. The plant has a cutting and a finishing department. The company uses departmental overhead rates to apply overhead to products. Overhead is applied in the cutting department using machine hours and overhead is applied in the finishing department using direct la ur hours. The 2019 budget for the plant was as follows: Cutting Department Finishing Department Manufacturing overhead costs $ 10,455,000 $ 5,800,000 Direct manufacturing labour costs $ 940,000 $3,800,000 Direct manufacturing labour hours 36,000 160,000 Machine hours 205,000 32,000 During the month of September 2019, the job cost sheet for Job 777 showed the following: Cutting Department Finishing Department Direct materials used $ 15,500 $ 5,000 Direct manufacturing labour costs $ 400 $ 1,100 Direct manufacturing labour hours Machine hours 90 50 50 140 Actual results at the end of 2019 were as follows: Cutting Department Finishing Department Manufacturing overhead costs $ 10,600,000 $ 5,810,000 Direct manufacturing labour costs $ 833,000 $ 4,073,000 Direct manufacturing labour hours 35,000 155,000 Machine hours 211,000 31,000 REQUIRED: a.

Determine the total underapplied or overapplied overhead in the Finishing department for the year. d. Why might Forest Products Company use departmental overhead rates instead of one plant- wide overhead rate
