U.S.-based private equity firm Warburg Pincus has secured $14 million in the first close of its latest flagship fund.

Warburg Pincus started fundraising for its Warburg Pincus Global Growth LP with an initial target of $13.5 billion.

The company, which is likely to hold a final close of the fund early next year, could raise as much as $17 billion based on investor demand.

In 2015, Warburg Pincus scored $13.4 billion for its previous flagship fund, Warburg Pincus Private Equity XII LP.
