Global Measurement Solutions (GMS) specialises in manufacturing precision measuring instruments popular for use by industrial companies. The measuring instruments are produced in two stages: Assembly and Testing
GMS has no beginning inventories as all units produced in the previous year were sold by the end of the year. At the beginning of the year Global has an order for 9,000 units. GMS uses multiple allocation bases, with the predetermined overhead rates based on materials used in assembly and direct labour hours in testing.
