The DWS GNMA Fund - Class C (GCGGX) is a mutual fund that primarily invests in mortgage-backed securities issued or guaranteed by the Government National Mortgage Association (GNMA). These securities are backed by the full faith and credit of the U.S. government, making them relatively low-risk investments. The fund aims to provide investors with a steady stream of income through interest payments from the underlying securities. Class C shares typically have higher expense ratios and may have a contingent deferred sales charge (CDSC) if shares are redeemed within a certain time period. This fund is managed by DWS Investments, a global asset management company.
