Under normal circumstances, the fund invests at least 80% of its assets in investment grade “California municipal securities” or other investments with similar economic characteristics. California municipal securities are securities the interest on which is exempt from regular federal income tax and California State personal income taxes. The fund’s 80% policy may not be changed without a shareholder vote. Interest on California municipal securities may be subject to the federal alternative minimum tax.

California municipal securities include debt obligations issued by the State of California and its political subdivisions, agencies and public authorities, certain other governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers. These securities include participation or other interests in municipal securities issued or backed by banks, insurance companies and other financial institutions.

Some municipal securities, such as general obligation issues, are backed by the issuer’s taxing authority, while other municipal securities, such as revenue issues, are backed only by revenues from certain facilities or other sources and not by the issuer itself.

The fund focuses on investment grade bonds (that is, securities rated in the Baa/BBB categories or above or, if unrated or deemed to be unrated by the subadviser, determined to be of comparable credit quality by the subadviser) but may invest up to 20% of its assets in below investment grade bonds (commonly known as “high yield” or “junk” bonds).

The fund may invest up to 20% of its assets in unrated securities that the subadviser determines to be equivalent to investment grade.

The fund may invest in securities of any maturity. The fund normally maintains an average effective portfolio maturity of between three and ten years. The average effective portfolio maturity of the fund is a weighted average of all the maturities of the securities in the portfolio, computed by weighting each security’s effective maturity, as estimated by the subadviser, by the market value of the security, and any cash in the portfolio. For the purposes of determining the fund’s average effective maturity, a security’s maturity date will generally be deemed to be the next interest rate reset date for an adjustable rate security or, if earlier, the date of the next demand feature such as a put feature, when the fund would be entitled to

  

receive payment of principal and interest. The subadviser may also take into account estimated future prepayments on securities, such as mortgage-backed securities, with uncertain future cash flows and estimations of call features and similar features and options. These estimates may prove to be incorrect. 

The fund may also invest in securities of other open‑end or closed‑end investment companies, including exchange-traded funds (“ETFs”), that invest primarily in municipal securities. 

Instead of, and/or in addition to, investing directly in particular securities, the fund may use instruments such as derivatives, including options, futures contracts and inverse floating rate instruments issued in tender option bond transactions, and other synthetic instruments that are intended to provide economic exposure to the securities or the issuer or to be used as a hedging technique. The fund may use one or more types of these instruments without limit, except that these instruments are taken into account when determining compliance with the fund’s 80% policy. For additional information regarding derivatives, see “More on the fund’s investment strategies, investments and risks—Derivatives” in the Prospectus. 

The fund may also engage in a variety of transactions using derivatives in order to change the investment characteristics of its portfolio (such as shortening or lengthening duration) and for other purposes. The fund may leverage its assets by investing proceeds received through tender option bond transactions, which is considered a form of borrowing. See “More on the fund’s investment strategies, investments and risks—Tender option bonds” in the Prospectus. 

The fund is classified as “non‑diversified,” which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund.
