This newspaper has long argued that items such as goodwill and brand values should be excluded from balance sheets as they are nebulous, cannot be accurately calculated and give a false value to companies. So, we argue, does valuing companies on "revenue" and artificial straight line depreciation saying that fixed assets and profit are the only true measures of a company's value to shareholders. Once again, it is reported by a market regulator, a company is "writing down" goodwill. It's time for a radical rethink on how companies, especially listed companies, are valued.
