It also lowers investors' firm specific information processing costs and thereby facilitates a more precise valuation of financial information.Financial statements should always be compared to assist stakeholders in determining the performance of the organisation. The statement should possess the qualitative characteristics of accounting information which will help the stakeholders make necessary decisions based on the performance through comparison at every point in time (Farouk, Magaji & Eega, 2019).
