B74 The Standard encourages, but does not require, separate disclosure of the effects of the factors resulting in changes to the carrying amount of biological assets, physical change and price change, when there is a production cycle of more than one year. Physical change is attributable to changes in the assets themselves while price change is attributable to changes in unit fair values.

B75 Some argue that the separate disclosure should be required since it is useful in appraising current period performance and future prospects in relation to production from, and maintenance and renewal of, biological assets. Others argue that it may be impracticable to separate these elements and the two components cannot be separated reliably.

B76 The Board concluded that the separate disclosure should not be required because of practicability concerns. However, the Board decided to encourage the separate disclosure, given that such disclosure may be useful and practically determinable in some circumstances. The separate disclosure is not encouraged when the production cycle is less than one year (for example, when raising broiler chickens or growing cereal crops) since that information is less useful in that circumstance.

B77 Some argue that physical changes should be included in net profit or loss and that price changes should be included directly in equity, through the statement of changes in equity. The Board rejected this approach because both components are indicative of management's performance.
