Buyout firms Trilantic Capital Partners and Gresham Private Equity have negotiated extensions to their fund investment periods with investors, becoming the latest European buyout firms seeking additional time to deploy capital.

Trilantic Capital Partners, the former private equity arm of collapsed investment bank Lehman Brothers, has agreed a 12-month fund extension on its European fund after three-quarters of investors voted to extend the investment period until May 2013, according to a person close to the situation. The €574m fund was raised in 2007.
