The U.S. may announce charges as early as this week against former London-based JPMorgan Chase & Co. employees related to allegations they tried to conceal losses last year, Bloomberg News reported yesterday. The investigation has centered on whether employees attempted to inflate the value of trades on the bank’s books by mismarking them. Federal officials are considering charges related to mismarking books and falsifying documents. JPMorgan first disclosed losses in its Chief Investment Office’s London unit in May 2012 after what Chief Executive Officer Jamie Dimon called “egregious mistakes” in managing credit-derivative positions. The trades by Bruno Iksil, nicknamed the London Whale because of the size of his holdings, eventually lost more than $6.2 billion for the bank.
