Final answer:
The best evidence concerning the net realisable value of inventory is post year-end sales invoices and post year-end sales price lists because they provide actual sales data and expected selling prices, respectively.
Step-by-step explanation:
When assessing the net realisable value of inventory, it is important to determine the best evidence available. Of the options provided, the two that constitute the best quality evidence are:
- Post year-end sales invoices
- Post year-end sales price list
Post year-end sales invoices provide actual data on what prices the inventory items were sold for after the year-end. This reflects the realisable value directly from the market and offers strong evidence for estimating net realisable value. On the other hand, Post year-end sales price list can provide an indication of the prices at which the company expects to sell the remaining inventory, which is useful when there are no actual sales yet to refer to.
While company's controls over inventory counting can ensure the physical inventory is accurately counted, it does not give information about the realisable value. Post year-end sales orders do not necessarily reflect completed sales or the prices at which goods will eventually be sold.
