Amberjack Company is trying to decide on an allocation base to use to assign manufacturing overhead to jobs. The company has always used direct labor hours to assign manufacturing overhead to products, but it is trying to decide whether it should use a different allocation base such as direct labor dollars or machine hours. Actual and estimated data for manufacturing overhead, direct labor cost, direct labor hours, and machine hours for the most recent fiscal year are summarized here: Direct labor cost Estimated Value Actual Value Manufacturing overhead cost $ 595,000 $ 656,000 $ 397,000 $ 451,000 16,600 hours 7,600 hours 18,100 hours 8,600 hours Direct labor hours Machine hours Required: 1. Based on the company's current allocation base (direct labor hours), compute the following: a. Predetermined overhead rate. Note: Round your answer to 2 decimal places. b. Applied manufacturing overhead. Note: Round your intermediate calculations to 2 decimal places and final answer to the nearest whole dollar amount. c. Over- or underapplied manufacturing overhead. Note: Round your intermediate calculations to 2 decimal places and final answer to the nearest whole dollar amount. 2. If the company had used direct labor dollars (instead of direct labor hours) as its allocation base, compute the following: a. Predetermined overhead rate. Note: Round your answer to 2 decimal places, i.e. 3.63%. b. Applied manufacturing overhead. Note: Round your intermediate calculations to 2 decimal places and final answer to the nearest whole dollar amount. c. Over- or underapplied manufacturing overhead. Note: Round your intermediate calculations to 2 decimal places and final answer to the nearest whole dollar amount. 3. If the company had used machine hours (instead of direct labor hours) as its allocation base, compute the following: a. Predetermined overhead rate. Note: Round your answer to 2 decimal places. b. Applied manufacturing overhead. Note: Round your intermediate calculations to 2 decimal places and final answer to the nearest whole dollar amount. c. Over- or underapplied manufacturing overhead. Note: Round your intermediate calculations to 2 decimal places and final answer to the nearest whole dollar amount. 4. Based on last year's data alone, which allocation base would have provided the most accurate measure for applying manufacturing overhead costs to production? 1a. Predetermined Overhead Rate 1b. Applied Manufacturing Overhead 1c. Manufacturing Overhead 2a. Predetermined Overhead Rate 2b. Applied Manufacturing Overhead 2c. Manufacturing Overhead 3a. Predetermined Overhead Rate 3b. Applied Manufacturing Overhead 3c. Manufacturing Overhead 4. Most accurate measure per DLH % of direct labor cost per machine hour
