Under IFRS, no adjustment is required for the increase in market value of inventory if it is lower than the net realizable value.
Under IFRS, inventory is accounted for at the lower of cost and net realizable value. Net realizable value is the estimated selling price less the estimated selling costs.
In this case, the cost of the inventory is $720,000 and the estimated selling cost is $50,000, resulting in a net realizable value of $670,000. Since the market value of the inventory at the end of the reporting period is higher than the net realizable value, there is no impairment and no adjustment is required.
Therefore, there would be no entry required for the increase in market value of the inventory from $740,000 to $810,000 under IFRS.
