Important Information Regarding U.S. Withholding Tax

TORONTO, ONTARIO--(Marketwire - Jan. 18, 2013) - (TSX:XAL)(TSX:XCR)(TSX:XGC)(TSX:XGR)(TSX:XHY)(TSX:XIG)(TSX:XPF)

Seven Canadian iShares(R) Funds managed by BlackRock Asset Management Canada Limited (the "Funds") invest in one or more U.S. Regulated Investment Companies ("RICs") that earn and distribute qualified interest-related dividends. On January 2, 2013, the U.S. President signed into law the American Taxpayer Relief Act of 2012, (the "Act"). The Act retroactively extended the U.S. withholding tax exemption for qualifying income distributed by the relevant RICs to foreign entities, including the Funds. As a result, the Funds are in a position to reclaim a portion of the taxes withheld in 2012.

The Funds will record a tax reclaim receivable amount on January 21, 2013 which will result in an increase in the net asset value and net asset value per unit of the Funds.

Prior to the expiration of the previous law in 2012, the Funds benefitted from an exemption from U.S. withholding tax on qualifying income received from investments in RICs. However, this exemption tentatively expired in 2012 and the Funds were subject to withholding at a rate of 15% for a portion of the year. Without further changes in legislation or a further extension of the withholding tax exemption, the U.S. withholding tax exemption on qualifying income will expire with respect to distributions paid by US RICs with fiscal years beginning after December 31, 2013.
