Accounting, therefore, entails a statement of accepted accounting rules. These rules form the structure of reference for the financial reporting. The conceptual framework forms the foundation for expansion of new accounting criteria and the assessment of those standards that are already in place. Further, it forms the basis for establishing which events should be accounted for and how the same should be released to the accountants. Functions of conceptual framework Conceptual framework lays out the objectives of the financial statements. Financial statements are meant to reflect the financial standing of institutions.

Information is relevant when it is able to influence the economic decisions of the users. It should be predictive in the sense that a user must be able to make reliable predictions about an entity’s future by using the information. It must also be confirmatory which is achieved when it confirms the previous predictions of users regarding an entity. Thirdly, the information needs to be reliable. Information that is free from material errors and bias is regarded as reliable. Reliable information is faithfully represented, neutral, pru dent, and complete and substance is given priority over legal forms of various elements.Â
