BlackRock Asset Management Canada Limited announces today the revised estimated annual reinvested distributions for the iShares exchange traded funds for the 2009 tax year. These annual reinvested distributions generally represent realized capital gains within the funds. The reinvested distributions are not paid in cash but will be reported as taxable distributions and can be used to increase the investor's adjusted cost base of the fund. These estimated reinvested distributions do not include the fourth quarter cash distributions which are reported in a separate press release. These estimates replace the previous estimates issued in a press release dated December 2, 2009.

Unitholders of record on December 30, 2009 will receive reinvested distributions payable on December 31, 2009. The ex-dividend date will be December 24, 2009. The actual taxable amounts of reinvested and cash distributions for 2009, including the tax characteristics of the distributions, will be reported to brokers (through CDS Clearing and Depository Services Inc.) early in 2010.

The following chart shows the estimated annual reinvested distributions per unit for each of the iShares funds.
