*Securities primarily traded in the U.S. market use CUSIP identifiers. Securities primarily traded abroad use a 6-digit SEDOL™ with a trailing check digit and a "99" at the beginning for internal coding purposes. If a SEDOL™ is unavailable, the first seven digits of the ISIN are used.

Please note: Total allocation percentages may not equal 100% due to rounding or omission of holdings of less than 1%. Information on certain fund holdings of less than 1% may not be widely available and may not be included in this list.
