July 26 (Reuters) - Pershing Square USA, a fund managed

by billionaire Bill Ackman, has postponed its initial public

offering, according to a notice on the New York Stock Exchange's

website on Friday.

The delay follows Ackman's recent slashing of the

fundraising target for the U.S. fund.

The IPO was originally scheduled to price on Monday.

Pershing Square did not immediately respond to a Reuters

request for comment.
