JPMorgan is going through some changes, according to an internal memo issued on Wednesday.  Only last month were members of the firm's elite leaving the firm in a wake of the London Whale losses.  This month, the largest bank in the United States by assets heralds another change, this one among better circumstances.

The corporate and investment banking division will be split into 2 units going forward.  Staff changes include:

• Carlos Hernandez, who held the reins of the equities business, will now head up prime brokerage services for the bank's hedge fund clients
• Tim Throsby will take over as global head of equities
• Blythe Masters, the long-time head of JPMorgan's commodities division, will oversee regulatory affairs for the corporate and investment bank

In other parts of the firm, Craig Delany, who was most recently the COO of JPMorgan's mortgage banking unit, would take the helm of the chief investment office, vacated by Ina Drew last month who left following the firm's loss, now estimated at $5.8 billion.
