Companies are being urged to slash their company statements by 30 per cent to prevent readers becoming bogged down in detail.
The recommendations are contained in a report by the New Zealand Institute of Chartered Accountants and the Institute of Chartered Accountants of Scotland to the International Accounting Standards Board (IASB).
The joint working party said the increasing size of annual reports had become a concern to the financial reporting community, with many key messages about a company's performance becoming drowned in detail.
In the UK alone there was a 44 per cent increase in the size of listed companies financial statements between 2005 and 2010.
"So much financial data is hindering, not helping communication," the working party said.
