Description of iShares^SM
iShares are exchange-traded securities that represent ownership in over 50 different index funds, each designed to provide investment returns corresponding to the price and yield performance, before fees and expenses, of a particular index compiled by one of five index providers: Standard & Poor’s (a division of The McGraw-Hill Companies, Inc.), Dow Jones & Company, Cohen & Steers, The Nasdaq Stock Market, Inc., Frank Russell Company and Goldman Sachs Group. There is no assurance that the price and yield performance of each particular index for each fund can be fully matched.

Note: Underlying Trading Value is the market value of a Creation Unit’s Deposit Securities, including the Estimated Cash Component per Creation Unit, and is updated every 15 seconds. The Estimated Cash Component per Creation Unit represents the estimated total cash amount in dollars per Creation Unit anticipated to be required in connection with the current trading day’s creation or redemption requests. This value may include a cash-in-lieu amount for shares of any component stock, which may be excluded from the Creation Unit. Total Cash Component per Creation Unit represents the actual total cash amount, in dollars per Creation Unit, required in connection with the prior trading day’s creation or redemption requests. Net Asset Value, Estimated Cash Component per Creation Unit and Total Cash Component Per Creation Unit are all as of previous day’s close. Underlying Trading Value, Net Asset Value, and Final Dividend Payment are all on a per-share basis. Although iShares may be bought and sold on the exchange through any brokerage account, iShares are not individually redeemable from the Fund. Investors may acquire iShares, and tender iShares for redemption, through the Fund in Creation Unit aggregations only.
