The US Commodity Futures Trading Commission’s years-long litigation against the former CEO of MF Global Holdings Ltd. has concluded with a settlement. After the brokerage firm MF Global went bankrupt in a 2011 liquidity crisis, the CFTC sued CEO Jon Corzine for dipping into nearly $1 billion of segregated client funds in an effort to obtain badly needed liquidity. The settlement requires Corzine to pay a $5 million fine out of his own pocket, rather than from insurance.
