Rhea-AI Filing Summary

PIMCO Corporate & Income Opportunity Fund is updating its core investment policy. Effective August 28, 2026, the fund will invest, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes in corporate debt obligations and/or income-producing investments, which may include non-corporate issuers.

The fund broadens and clarifies what counts as income-producing investments, including fixed income instruments, dividend-paying equities and related derivatives, and states that certain derivatives will be included when measuring compliance with the 80% policy. The policy cannot be changed without giving shareholders at least 60 days’ written notice, and the prospectus and Statement of Additional Information are being revised to reflect these changes.

income-producing investments financial
"in corporate debt obligations of varying maturities and/or income-producing investments..."
Fixed Income Instruments financial
"“Fixed Income Instruments” include bonds, debt securities, bank loans and other similar instruments..."
Fixed income instruments are loans or IOUs issued by governments, companies, or other organizations that promise regular payments and return of the original amount at a set future date. For investors they matter because they provide predictable income and can reduce overall portfolio risk—think of them as renting out your money for a steady paycheck—while their value can still change with interest rates and issuer credit quality.
derivatives financial
"derivatives on either of the foregoing, derivatives providing exposure to other types of income-producing instruments..."
Derivatives are financial contracts whose value depends on the price or performance of another asset, such as a stock, bond, commodity, currency or interest rate. Investors use them to hedge against risk, to speculate on future price moves, or to gain exposure without owning the asset — like buying insurance or placing a leveraged bet — so they can both protect portfolios and magnify gains or losses, affecting risk and market liquidity.
