The Securities Industry Assn. has joined with the National Investor Relations Institute in asking the SEC to delay new rules designed to ensure that key corporate information is released to all investors at the same time.

The SEC’s rule, Regulation FD (for Fair Disclosure), was approved by the commission in August, with an Oct. 23 start date. But the securities industry and the investor-relations group argue that companies need more time to draft earnings releases and plan investor conference calls that comply with the rule.
