There's been a significant change among the leadership at Barclays Global Investors' iShares division. Jennifer Grancio, previously head of sales and marketing for iShares in Europe, is returning to the other side of the pond.

Grancio will once again be based in San Francisco, where she will head up a distribution strategy team for the U.S. She will report to Mike Latham, the regional head of iShares in the Americas.

Her previous responsibilities will be divided between iShares' head of European sales, Andrea Morresi, and head of European marketing, Rick Andrews.

At the end of the first quarter, according to a report from Morgan Stanley, there were 139 iShares ETFs trading in Europe, with a total of $58.53 billion in assets, which works out to about 40.3% of total European assets invested in ETFs. 

Grancio's move comes on the heels of the announcement of Deborah Fuhr's departure from Morgan Stanley where she had been the head of its London-based Investment Strategies group.
