The fair value, as treated by other accounting standards, is an important element for the
economic information users, by presenting the key elements used in its estimation. Calculating the
update rate and the evaluation techniques used in determining the volume of agricultural assets, can
have significant effects over the fair value estimation. All evaluations influence the profit and loss
account, and directly influence the revenues and expenses: modifications of the fair value at the year-end and revenues generated by initial evaluations. Therefore, the modifications influenced by the
market variations, such as physical modifications are due to biological alteration of plants and animals.
These modifications are not separately recognized in the profit and loss account and in capital
resources, but represent the transaction result. IAS 41 standard is one of the few standards that control
accounting rules for single sectors by applying thefair value estimation for assets that are not
classified as financial instruments, such as IAS 39classifies them.
