NEW YORK: JPMorgan Chase ’s board will consider releasing an internal report this week that faults chief executive officer Jamie

oversight of a division that lost more than $6.2 billion on botched trades, according to two people with direct knowledge of the matter.

Dimon’sThe final report, which builds on a preliminary analysis released in July, is critical of Dimon, 56, former chief financial officer Doug Braunstein, 51, former chief investment officer Ina Drew and others for inadequately supervising traders in a UK unit that built up a large and illiquid position in credit derivatives last year, these people said.The report, which isn’t yet finished, will be presented to the board when it meets on January 15. The directors will then vote on whether to release it to the public when the bank announces fourth-quarter earnings the following day, the people said, asking not to be named because the report is not yet public. Joe Evangelisti , a spokesman for the New York-based bank, declined to comment and said that each member of the board also declined to comment.UK regulatory authorities have asked the bank to keep its findings private until they can ensure it adheres to European privacy laws that protect individuals, one of the people said. The report describes executives at JPMorgan and their role in the loss.The bank’s analysis in July said that London traders may have intentionally mismarked some of their positions and sought to hide the full amount of their losses. Bruno Iksil , the UK trader nicknamed the London Whale because his trading book was so large, made a wrong-way bet on credit derivatives that led to the company’s single biggest trading loss.At one point, as much as $51 billion in shareholder value was wiped out. The bank has come under increasing scrutiny and regulatory oversight in the aftermath of the US housing crisis. The trading debacle is under investigation by the US justice department Federal Bureau of Investigation and the Securities and Exchange Commission , among other agencies.
