TowerBrook Capital Partners is making its first foray into structured opportunities, with a fund dedicated to making non-controlling investments.

The private equity firm has secured commitments of more than $800 million for its first structured opportunities fund in a first close, the point at which a firm can start making investments from a fund. The firm has already beaten its $600 million target, and does not have an upper limit for the fund, according to a person familiar with the matter.
