Barclays is considering suing to recover more than $400 million lost in a Bear Stearns hedge fund that placed big bets on subprime residential mortgage-backed securities, according to the Wall Street Journal. Barclays had been an investor in Bear Stearns Asset Management's High-Grade Structured Credit Strategies Enhanced Leverage Fund, which is now worth nothing. Barclays also extended one loan for $200 million that has since been paid back, and offered to extend another loan for $250 million, which was never extended. In addition to its option to force litigation, Barclays may negotiate a settlement with Bear.
