Over the years, corporate and institutional investors had suffered huge financial losses as a result of poor or wrong investment decisions taken on the basis of manipulated financial information. Studies have shown globally that the practice of financial report misrepresentation commonly leads to loss of credibility, integrity and confidence in accounting information and the earnings become questionable. This situation now calls for additional sources of information that would enhance the quality of corporate investment decision.
