Golub Capital Partners, a New York-based provider of debt financing to private equity sponsors, has withdrawn registration for a $150 million IPO. No reason was given. The firm had planned to trade on the Nasdaq, with Wachovia Securities serving as lead underwriter. The publicly-traded entity would have served as a holding company for Golub's funds, including the $1 billion Fund V closed earlier this year. www.golubcapital.com
