The Fund ordinarily invests in a diversified portfolio of floating and/or fixed-rate debt instruments. The fund may invest without limit in high yield, below investment grade, debt instruments. However the Fund may not invest more than 20% of its total assets in securities that are, at the time of purchase, rated CCC/Caa or below or unrated but judged by PIMCO to be of comparable quality. High-yield bonds typically have a lower credit rating than other bonds. Lower rated bonds generally involve a greater risk to principal than higher rated bonds. The use of leverage may cause a fund to liquidate portfolio positions at a disadvantageous time to satisfy its obligations or to meet segregation requirements. Leverage, including borrowing, may cause a fund to be more volatile than if the fund had not been leveraged, which may increase the risk of investment loss. This Fund may use derivative instruments for hedging purposes or as part of its investment strategy. Use of these instruments may involve certain costs and risks such as liquidity risk, interest rate risk, market risk, credit risk, management risk and the risk that a fund could not close out a position when it would be most advantageous to do so. Portfolios investing in derivatives could lose more than the principal amount invested in those instruments. Investing in non-U.S. securities entails additional risks, including political and economic risk and the risk of currency fluctuations; these risks may be enhanced in emerging markets.

Returns are calculated by subtracting the value of a share at the beginning of the period from the value at the end and dividing the difference by the initial value, expressing the result as a percent change. The calculation assumes that all distributions during the period have been reinvested on the payable dates, at NAV or at market price according to how the returns are labeled. The returns do not reflect broker sales charges or commissions. Net asset value (NAV) is total assets less total liabilities divided by the number of shares outstanding.

Dividend Yield (Market) is calculated by annualizing the most recent regular distribution per share and dividing by the closing market price listed above. The Fund's distributions may be comprised of ordinary income, net capital gains, return of capital or a combination thereof. Distribution rates on Fund common shares are subject to change and are not a quotation of fund performance. Please refer to the most recent Section 19 Notice, if applicable, for additional information regarding the composition of distributions.
