Hasty revisions to controversial accounting rules on how to value assets threaten to undermine investor confidence in company accounts, a group of senior investors and analysts has warned. Members of the Corporate Reporting Users Forum, a pan-European group of investors and analysts, urge the European Commission not to make more amendments to accounting rules.

The Commission is hosting a meeting on Tuesday involving regulators, banking and insurance representatives, investors and accountants to discuss changes to the rules. The resulting “wishlist” will then be presented to the International Accounting Standards Board, which sets accounting rules for more than 100 countries, including the European Union.
