American Funds Mortgage Fund Class F-1 

This fund typically allocates at least 80% of its total assets to investments connected to mortgages. These include debt instruments collateralized by mortgage loans and contracts for their future delivery, such as "to be announced" (TBA) contracts and mortgage dollar rolls. The portfolio's main emphasis is on mortgage-related securities either sponsored or guaranteed by the U.S. government. This encompasses securities issued by government-sponsored enterprises (GSEs), even those not explicitly backed by the full faith and credit of the U.S. government, as well as mortgage securities from private issuers.
