You have commenced planning the audit of FC, as part of your preliminary planning you visit the factory. While there you notice there are large quantities of high value raw materials, genuine silks and other similar high value items stored in an unlocked store room at one end of the building. Workers would walk in select bolts of material and take them back to the cutting tables. On enquiry you are told that each night the storeman notes down the bolts of material in the store, and uses those notes to calculate re-order requirements. Required: Given the above information critically analyse the control system surrounding raw materials, and explain in depth, using the Audit Risk Model as a tool, what effect the above information will have on your approach to the audit of raw material inventory.
