JPMorgan Chase & Co. (JPM) is being sued by a trader who says he accepted a contract from the investment bank because a typographical error made him believe he would be paid 10 times what was actually offered. Kai Herbert, a Switzerland-based currency trader, is suing JPMorgan for about 580,000 pounds ($920,000), his lawyers said at a trial in London this week. The original contract said Herbert’s annual pay would be 24 million rand ($3.1 million). JPMorgan blamed the mistake on a typographical error and said the figure should have been 2.4 million rand, according to court documents. (full story)
