What is materiality principle

According to this principle, only those items or information should be disclosed that have material effect and relevant to the users. So, item having an insignificant effect or being irrelevant to user need not be disclosed separately, these may be merged with other item.

If the knowledge of any information may effect the decision of a user of account, is termed as material information.
It should be noted that an item material for one enterprise may not be material for another enterprise. E.g. an item of expenses ϕ 50,000 is material for an enterprise having turnover of ϕ 1,50,000 but it is not material for an enterprise having turnover of ϕ 100 crore.
The nature of transaction should be taken into consideration for materiality of information. E.g. a difference of ϕ 200 in the valuation of stock may be immaterial but the difference of ϕ 50 in cash could be termed as material.
