To be announced (TBA) is a placeholder term used very broadly in event planning to indicate that although something is scheduled or expected to happen, a particular aspect of it remains to be fixed or set. Other versions of the term include to be confirmed (TBC) and to be determined, discussed, defined, decided, declared, or done (TBD).

Investment type[edit]
"TBA" (meaning "to be announced") is also used to describe a specific type of simple mortgage investment, the forward mortgage-backed security. This is used to indicate that the investor is acquiring some portion of a pending pool of as-yet unspecified mortgages, which will be specified at a given delivery date.[7] This usage has existed at least since the 1980s.[b]
