JP Morgan Chase is setting aside $6bn (£2.9bn) to cover potential litigation as it agrees to buy stricken Wall Street giant Bear Stearns for just $240m (£119m).

Following the announcement on 16 March that it is buying the bank for a fraction of its previous value, JP Morgan said it is estimating the cost of the transaction at around $6bn – taking into account the potential of litigation stemming from the drop in Bear Stearn’s stock value and severance costs.
