 projected market returns, fluctuations in market interest rates, Fund performance, and other factors. There can be no assurance that a change in market conditions or other factors will not result in a change in the Fund’s distribution rate or that the rate will be sustainable in the future. For instance, during periods of low or declining interest rates, the Fund’s distributable income and dividend levels may decline for many reasons. For example, the Fund may have to deploy uninvested assets (whether from sales of Fund shares, proceeds from matured, traded or called debt obligations or other sources) in new, lower yielding instruments. Additionally, payments from certain instruments that may be held by the Fund (such as variable and floating rate securities) may be negatively impacted by declining interest rates, which may also lead to a decline in the Fund’s distributable income and dividend levels. How the Fund Manages Risk Investment Limitations The Fund has adopted certain investment limitations designed to limit investment risk and maintain portfolio diversification. These limitations are fundamental and may not be changed without the approval of the holders of a majority of the outstanding Common Shares and Preferred Shares voting together as a single class, and the approval of the holders of a majority of the Preferred Shares voting as a separate class. The Fund may not: 1. Concentrate its investments in a particular “industry,” as that term is used in the Investment Company Act of 1940, as 82 Base Prospectus | PIMCO Corporate & Income Opportunity Fund Base Prospectus amended, and as interpreted, modified, or otherwise permitted by regulatory authority having jurisdiction, from time to time. 2. With respect to 75% of the Fund’s total assets, purchase the securities of any issuer, except securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities or securities issued by other investment companies, if, as a result, (i) more than 5% of the Fund’s total assets would be invested in the securities of that issuer, or (ii) the Fund would hold more than 10% of the outstanding voting securities of that issuer. For the purpose of this restriction, each state and each separate political subdivision, agency, authority or instrumentality of such state, each multi-state agency or authority, and each obligor, if any, is treated as a separate issuer of municipal bonds. 3. Purchase or sell real estate, although it may purchase securities secured by real estate or interests therein, or securities issued by companies which invest in real estate, or interests therein
