BlackRock, the world's largest money manager, filed an application with the SEC for its iShares exchange-traded funds to follow its own indexes rather than those developed by third parties such as Standard & Poor's.
According to Bloomberg, the application, filed on Aug. 25 "would allow future and existing funds to use in-house indexes the firm will create."
The news service notes iShares, a San Francisco-based subsidiary of BlackRock, ranks as the biggest provider of index-based ETFs with some $649 billion in assets under management in more than 460 funds.
