Osborn Manufacturing uses a predetermined overhead rate of $18.20 per direct labor-hour. This predetermined rate was based on a cost formula that estimates $218,400 of total manufacturing overhead for an estimated activity level of 12,000 direct labor-hours. The company actually incurred $215,000 of manufacturing overhead and 11,500 direct labor-hours during the period. Required: 1. Determine the amount of underapplied or overapplied manufacturing overhead for the period. 2. Assume that the company underapplied or overapplied overhead is closed to Cost of Goods Sold. Would the journal entry to dispose of the underapplied or overapplied overhead increase or decrease the companys gross margin? By how much?

1. Manufacturing overhead (either underapplied or overapplied) by how much?

2. The gross margin would (increase or decrease) by how much?
