After stocktaking for the year ended 31 May 20X9 had taken place, the closing inventory of Cobden Ltd was aggregated to a figure of £87,612.
During the course of the audit that followed, the under-noted facts were discovered:
1. Some goods stored outside had been included at their normal cost price of £570. They had, however, deteriorated and would require an estimated £120 to be spent to restore them to their original condition, after which they could be sold for £800.
2. Some goods had been damaged and were now unsaleable. They could, however, be sold for £110 as spares after repairs estimated at £40 had been carried out. They had originally cost £200.
3. One inventory sheet had been overcast by £126 and another undercast by £72.
4. Cobden Ltd had received goods costing £2,010 during the last week of May 20X9 but because the invoices did not arrive until June 20X9, they have not been included in inventories.
5. An inventory sheet total of £1,234 had been transferred to the summary sheet as £1,243.
6. Invoices totalling £638 arrived during the last week of May 20X9 (and were included in purchases and in trade payables) but, because of transport delays, the goods did not arrive until late June 20X9 and were not included in closing inventory.
7. Portable generators on hire from another company at a charge of £347 were included, at this figure, in inventories.
8. Free samples sent to Cobden Ltd by various suppliers had been included in inventories at the catalogue price of £63.
9. Goods costing £418 sent to customers on a sale or return basis had been included in inventories by Cobden Ltd at their selling price, £602.
10. Goods sent on a sale or return basis to Cobden Ltd had been included in inventories at the amount payable (£267) if retained. No decision to retain had been made.
