BlackRock Announces Unitholder Meetings Concerning Changes to

BlackRock Investments Canada Inc. (BlackRock Canada), an indirect, wholly owned
subsidiary of BlackRock, Inc. (NYSE:BLK), today announced that it has called a
special meeting of unitholders of each of the iShares Funds to be held on August
28, 2012, to approve a change of auditor of the iShares Funds and certain
related matters. At the special meeting of unitholders of SVR, unitholders will
also be asked to consider the conversion of SVR from a closed-end fund to an
exchange-traded fund (ETF) and certain related matters. 


Summary of Auditor Change 

BlackRock Canada is proposing to change the auditor of the iShares Funds, and
the other ETFs for which it acts as trustee and manager, from Ernst & Young LLP
to PricewaterhouseCoopers LLP. PricewaterhouseCoopers LLP is currently the
auditor of the ETFs and other funds managed by the Canadian affiliate of
BlackRock Canada. 


BlackRock Canada expects that having one auditor service the entire Canadian
iShares platform will lead to audit efficiencies and will allow BlackRock Canada
to leverage PwC's expertise, given its leadership position among audit firms in
respect of Canadian exchange-traded funds.


If the proposed change is approved by unitholders of the iShares Funds,
BlackRock Canada expects that the transition of the iShares Funds to the new
auditor will be fully implemented by September 30, 2012. 


Subject to unitholders approving the change, the prospectus disclosure of the
iShares Funds will be updated to reflect the change of auditor. 


Summary of SVR Conversion 

BlackRock Canada is proposing to convert SVR from a closed-end fund to an ETF.
The conversion of SVR to an ETF is expected to provide SVR unitholders with
potential benefits including: (i) greater market liquidity while maintaining its
stock exchange listing; (ii) more efficient trading as the market price of SVR's
units should be closer to their intrinsic net asset value; and (iii) the ability
to significantly increase the asset base of SVR as a result of the continuous
offering of its units as an ETF.  


In connection with the conversion to an ETF, BlackRock Canada expects to file a
preliminary prospectus qualifying the continuous distribution of SVR's hedged
common units and non-hedged common units in September 2012. SVR will also change
its name to "iShares Silver Bullion Fund" to reflect its conversion to an ETF.
The conversion will not change the investment objective or strategies of SVR. 


If the proposed change is approved by unitholders of SVR, the conversion of SVR
to an ETF will be effective upon the issuance of a receipt for a final
prospectus in relation to the continuous offering of the hedged common units and
non-hedged common units of SVR, which is expected to occur in the Fall of 2012.

on July 23, 2012 will be entitled to vote in respect of these matters.
