Lambda Ltd uses a normal costing system and closes off all overhead variances to the cost of goods sold at the end of each year. Its budgeted factory and non-manufacturing overhead expenses for the year were estimated to be $1,050,000 and $312,000 respectively. The budgeted direct labour hours (DLH) for the year were 7,000 hours in total. Direct labour hours have been used as the basis for overheads application. Jobs 111, 112 and 114 were completed during the year. Job 111 was invoiced in October and subsequently fully paid before the year end. Job 114 was invoiced in December and its payment was not settled as at the year-end. Job 112 was just completed but various administrative documents and certifications were outstanding at year end, and therefore, the invoice could not be issued. The following are information extracted from the accounting records:
