Former UBS trader Kweku Adoboli was charged on Friday morning with two additional counts of false accounting as he took the stand to give evidence in the London trial against him.
In an unexpected twist on the 27th day of the trial at Southwark Crown Court, theCrown Prosecution Service added the two additional charges to his existing indictment.
Adoboli now stands accused of two counts of fraud by abuse of position and four of false accounting.He denies all of the charges.
The Ghanaian-born trader, 32, is alleged to have caused a $2.3bn loss at UBS last year from unauthorised trading.
The two additional counts offalse accounting against himrelate to the so-called"umbrella" - a device allegedly used by Adoboli to conceal his trading profitsand losses.
The use of the umbrella had previously formed part of the two original counts offalse accounting against Adoboli. These two counts have now been amended inorder for the two new counts to be added.
Mr Justice Keith explained this morning: "It's not to add to the allegations against Mr Adoboli. It's been inserted into the indictment in order to clarify the allegations being made."
The original counts - two of fraud and two of false accounting - now solely refer to the alleged bookingof fictitious hedges to conceal Adoboli's true risk position.
The former ETF trader is accused of having booked fictitious trades to superficially reduce the exposure to the bank from potential losses on real trades he had made.
The jury heard earlier in thetrial that Adoboli had allegedly booked real trades that exposed UBS to losses that may have risen to$12bn in the summer of 2011. He allegedly hid this exposure through fake ETF trades, the court heard.
