Investment objective & strategy
As of Sept. 25, 2025 · prospectusObjective. The investment objective of BlackRock California Municipal Opportunities Fund (the California Fund or the Fund) is to provide shareholders with income exempt from Federal and California income taxes.
Strategy. Under normal circumstances, the Fund will invest at least 80% of its assets in California municipal bonds. For the purposes of the foregoing 80% policy, assets are the Funds net assets, plus the amount of any borrowings for investment purposes. The Funds investments in derivatives will be counted toward the Funds 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. California municipal bonds are debt obligations issued by or on behalf of a governmental entity in California or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax … Under normal circumstances, the Fund will invest at least 80% of its assets in California municipal bonds. For the purposes of the foregoing 80% policy, assets are the Funds net assets, plus the amount of any borrowings for investment purposes. The Funds investments in derivatives will be counted toward the Funds 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. California municipal bonds are debt obligations issued by or on behalf of a governmental entity in California or other qualifying issuer that pay interest that, in the opinion of bond counsel, is excludable from gross income for Federal income tax purposes (except that interest may be includable in taxable income for purposes of the Federal alternative minimum tax) and exempt from California income tax. Municipal bonds also include short-term tax-exempt obligations like municipal notes, variable rate demand obligations, private activity bonds and insured municipal bonds. The Fund may invest in both fixed rate and variable rate obligations. At least 50% of the Funds assets will be invested in investment grade securities. Investment grade securities are securities which are rated in the four highest categories by at least one of the major rating agencies or determined by the management team to be of similar quality. The Fund may invest up to 50% of its assets in non-investment grade bonds (commonly called high yield or junk bonds). Non-investment grade bonds are bonds that, at the time of acquisition, are rated in the lower rating categories of the major rating agencies (BB or lower by S&P Global Ratings or Fitch Ratings or Ba or lower by Moodys Investor Service, Inc.) or are determined by Fund management to be of similar quality. Split rated bonds will be considered to have the higher credit rating. Split rated bonds are bonds that receive different ratings from two or more rating agencies. The Fund may invest in bonds of any maturity. Under normal circumstances, the Fund seeks to maintain an average portfolio duration of zero to ten years. Duration is a mathematical calculation of the average life of a bond (or bonds in a bond fund) that serves as a useful measure of its price risk. Each year of duration represents an expected 1% change in the net asset value of a bond fund for every 1% immediate change in interest rates. For example, if a bond fund has an average duration of ten years, its net asset value would be expected to fall about 10% when interest rates rise by one percentage point, assuming all other factors remain equal. Conversely, the bond funds net asset value would be expected to rise about 10% when interest rates fall by one percentage point, assuming all other factors remain equal. Duration, which measures price sensitivity to interest rate changes, is not necessarily equal to average maturity. The Funds average weighted duration may vary significantly from time to time depending on the views of Fund management. The Funds investment process begins with bottom-up, fundamental analysis focused on sector and security selection, and then incorporates a macroeconomic framework for evaluating and managing risk, including geographic, technical and economic risk. The Funds investment process is generally expected to place greater emphasis on duration management and capital structure compared to that of a more traditional municipal fixed income fund. When selecting investments for the Fund, Fund management considers a variety of factors, including the credit quality of issuers and the yield and duration of the obligations. The Fund is permitted to engage in transactions in certain derivatives, such as interest rate futures, financial futures contracts and options thereon, for hedging purposes (including anticipatory hedges) or to seek to enhance returns. The Fund may also invest in other derivatives, such as swap agreements, including credit default swap agreements, for hedging purposes (including anticipatory hedges) or to enhance income. Derivatives are financial instruments whose value is derived from another security or an index. The Fund may use derivative instruments to hedge its investments or to seek to enhance returns. Derivatives allow the Fund to increase or decrease its risk exposure more quickly and efficiently than other types of instruments. The Fund may also invest in indexed and inverse floating rate obligations. The Fund may invest up to 20% of its assets in securities that are not California municipal bonds (including, but not limited to, taxable municipal bonds, U.S. Treasury and Government agency issues, and investment grade corporate bonds). The Fund may leverage its assets through the use of proceeds received through tender option bond transactions. In a tender option bond transaction, the Fund transfers municipal bonds or other municipal securities into a special purpose entity (a TOB Trust). A TOB Trust typically issues two classes of beneficial interests: short-term floating rate interests (TOB Floaters), which are sold to third party investors, and residual inverse floating rate interests (TOB Residuals), which are generally issued to the Fund. The Fund may invest in TOB Residuals and may also invest in TOB Floaters. The Fund will look through to the underlying municipal bond held by a TOB Trust for purposes of the Funds 80% policy. The Fund may also buy when-issued securities and participate in delayed delivery transactions. The Fund may engage in active and frequent trading of portfolio securities to achieve its primary investment strategies.
