(Bloomberg) -- Golub Capital is shutting down a $150 million credit-hedge fund that invested in distressed debt, following the market’s worst rout since the financial crisis.

The Chicago-based asset manager is closing the GC Synexus fund after losses exceeded 20% in 2015, according to a person with knowledge of the matter, who asked not to be identified because the information isn’t public. Daniel Posner, who led the fund after joining from D.E. Shaw & Co. in 2011, is leaving the firm, the person said.
