BlackRock Short Obligations Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Blackrock Funds.
Investment objective
The investment objective of BlackRock Short Obligations Fund (“Short Obligations Fund” or the “Fund”), a series of BlackRock Funds SM (the “Trust”), is to seek current income consistent with preservation of capital.
Principal investment strategy
Under normal market conditions, Short Obligations Fund will invest in U.S. dollar-denominated investment grade and short-term fixed and floating rate debt securities maturing in three years or less (with certain exceptions) and will maintain a dollar-weighted average maturity of 180 days or less and a dollar-weighted average life of 365 days or less. To achieve its investment objective, the Fund may invest in corporate securities, mortgage- and asset-backed securities, and money market instruments, including government, U.S. and foreign bank and commercial obligations, obligations issued by or on behalf of states, territories and possessions of the United States, the District of Columbia and their respective authorities, agencies, instrumentalities and political subdivisions and derivative securities such as beneficial interests in municipal trust certificates and partnership trusts, and repurchase agreements.
The Fund may invest in variable and floating rate instruments and when-issued and delayed delivery securities. The Fund invests a significant portion of its assets in securities issued by financial services companies, including banks, broker-dealers and insurance companies, and repurchase agreements secured by such obligations. Investment grade securities purchased by the Fund (or the issuers of such securities) will carry a rating of BBB-, or equivalent, or higher by at least one nationally recognized statistical rating organization (NRSRO) and short-term investments (or the issuers of such securities) will carry a rating in the highest two rating categories of at least one NRSRO (e.g., A-2, P-2 or F2 or better by Standard & Poors Ratings Services, Moodys Investors Service, Inc., or Fitch Ratings Inc., respectively), or if such investments are unrated, determined to be of comparable quality by BlackRock, at the time of investment.
