Hedge Fund Boss Jeff Gundlach Shreds Credit Suisse Creditors: 'Put on Your Big Boy Pants' (New York Post) Hedge fund boss Jeffrey Gundlach said outraged Credit Suisse creditors facing a $17 billion wipeout in rival UBS Group's rescue deal should "look in the mirror" and put on their "big boy pants" instead of griping about regulators. Gundlach, the CEO of DoubleLine Capital, had little sympathy for bondholders following revelations that Credit Suisse's additional tier 1 bonds would be subject to a "complete write-down" in the UBS deal – meaning their investments were worthless.
