This will increase Blackrock's reach in Switzerland and complement the existing iShares ETF fund range which has funds domiciled in Switzerland, Ireland and Luxembourg.
The combined firms will operate under the iShares name and all 58 of Credit Suisse's ETFs will be rebranded and renamed as iShares ETFs.
As of the end of May 2013, iShares' range of Swiss domiciled products had assets of CHF 7.7bn ($8.1bn) across equities, fixed income and gold funds.

David Blumer, head of Europe, Middle East and Africa (EMEA) for BlackRock said: "Switzerland is an important market for us. BlackRock has been helping Swiss clients meet their financial objectives for 10 years. We believe that more investors will have an interest in owning financial products denominated in Swiss francs and we want to serve them. This acquisition is just one sign of BlackRock's commitment to Switzerland and it deepens and expands our presence in this market."
Joe Linhares, head of iShares EMEA, said: "We are very excited that starting from today, we can move forward as one firm. This acquisition has combined two leading ETF providers with a common culture of responsible innovation, high quality products and a commitment to developing and expanding the ETF market. We'd like to thank our partners at Credit Suisse for their cooperation throughout this process, and we look forward to demonstrating the quality of our products and services to our new and existing Swiss clients."
