Extension Risk—Rising interest rates tend to extend the duration of mortgage-related securities, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, if the Fund holds mortgage-related securities, it may exhibit additional volatility.
Prepayment Risk—When interest rates decline, the value of mortgage-related securities with prepayment features may not increase as much as other fixed-income securities because borrowers may pay off their mortgages sooner than expected. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.
These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities. TBA (or “to be announced”) commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate and mortgage terms.
In addition, one of the major economic impacts of the COVID-19 pandemic has been loss of income, which has left many unable to repay their financial obligations, including their mortgage payments. [Since March 13, 2020, there have been a number of government initiatives applicable to federally backed mortgage loans in response to the economic impacts of COVID-19.] It is difficult to predict how the effects of COVID-19, or government initiatives relating to COVID-19, may affect the federally backed mortgage market, the U.S. mortgage market as a whole and the price of securities relating to the mortgage markets, and in turn, the Fund’s investments.
In the Funds’ Statement of Additional Information, the disclosure under “Investment Strategies, Policies, and Risks—Market Risks—Recent Economic Events” has been revised as follows:
