UBS "failed to question risk limit breach" The former manager of Kweku Adoboli failed to question why the former UBS trader had exceeded a $25m overnight risk limit, a jury was told. Ron Greenidge, who had been Mr Adoboli's line manager, agreed that he did not challenge the trader about his exposure when Mr Adoboli revealed his $40m position in an electronic chat message between the two men just after the market closed on an afternoon in April 2011. Charles Sherrard, defence barrister who was cross examining Mr Greenidge, told the court that Mr Greenidge had not raised the issue in the chat message. "This is I suggest the first example of where the culture and practices of the bank you both worked for was . . . risk limits actually didn't matter as long as you were making money," he told Mr Greenidge. Mr Greenidge replied: "That's not true." Mr Adoboli is accused of threatening the existence of UBS by "fraudulently gambling" away $2.3bn. He denies the charges against him. Details of Mr Adoboli's appraisals at the Swiss bank were also given to the jury at Southwark Crown Court. Mr Greenidge flagged in Mr Adoboli's 2009 appraisal that the defendant was at risk of "burn-out," the court heard. Mr Greenidge also did not disagree with claims that in 2011 UBS made a number of high-profile staff hires and the bank "became more aggressive" in terms of pursuing profit. Mr Sherrard told Mr Greenidge: "The mantra coming from above was revenue, revenue, revenue - that was the phrase being used." Part way through the morning when he was giving evidence Mr Greenidge became unwell, almost collapsing on the witness stand, and had to be helped to a chair. The court then took a short break before Mr Greenidge returned to give evidence. In Mr Adoboli's UBS appraisal another trader also said in an assessment of Mr Adoboli that he was "too nice" and "would benefit from additional cynicism." Mr Adoboli denies two charges of fraud by abuse of position and two charges of false accounting.
