You are the Assistant to Chief Accountant of Challenger Watch Ltd. You are trying to verify the accuracy of the ending WIP and finished goods inventories prior to closing the books for the year. You are assigned to take up the year end closing verification task. The year end balances shown on the company books are as follows:

	Units	Cost ($)
WIP, Dec 31 (labour and overhead 50% compl.)	300,000	660,960
Finished Goods, Dec 31	200,000	1,009,800

Materials are added to production at the beginning of the production process, and overhead is applied at the rate of 60% of direct labour cost. There was no finished goods inventory at the start of the year. A review of the company inventory and cost records has disclosed the following data:

	Units	Mat. Cost ($)	Lab. Cost ($)
WIP, Jan 1 (labour and overhead 80% compl.)	200,000	200,000	315,000
Started into production	1,000,000
Cost added during the year
Materials		1,300,000
Labour			1,995,000
