This document provides an introduction to annuities, outlining key information about different types of annuities. It explains that annuities insure against living too long by providing income that cannot be outlived. There are two main types - deferred annuities, where income payments begin at least one year after premium payments, and immediate annuities, where income begins within one year. Deferred annuities can be fixed, indexed, or variable, while immediate annuities are typically fixed or variable. The document also discusses risks and rewards associated with different annuity types along a spectrum from fixed to variable.
