US bank Citigroup has said it will take control of seven investment funds worth $49bn (£24bn) as it continues to ride out problems in the financial markets.
By taking control of seven structured investment vehicles (SIVs), it hopes to help the funds pay off debts without having to sell off assets cheaply.
Since the summer's credit crisis SIVs have been in the spotlight after they saw many investments plummet in value.
