What are the contents of fixed annuities?
An annuity is a contract. Its contents are "a contractual obligation from the issuing company". If you want to evaluate how your annuity is likely to fare, you're essentially asking whether or not its issuer will honor its contract. They're legally required to honor the contract, unless they go bankrupt. (Even if they do go bankrupt, you will be a creditor and may get a portion of the assets recovered by the bankruptcy process.) Generally, the issuer will take the proceeds and invest them in the stock market (or possibly in similar instruments - e.g. Berkshire-Hathaway bought a railroad and invests some money in it directly). They invest in these places because that's where the returns are. One of the reason that annuities may have a good rate on paper is that they may end up taking some of your principal, because many are structured as some form of survivor's insurance policy. Consider: If you're 65 years old and have some retirement savings, you'd like to be able to spend them without fear of them running out because you live longer than you expected (e.g. you survive to your 90s). So, you could invest in the stock market and hope for a 7% return indefinitely and then plan to spend the returns - but if those returns don't materialize for a few years because there's a big stock market crash, you're in big trouble! Or, you could buy an annuity contract which will pay you 7% a year (or more!) until you die. Then you're guaranteed the returns unless the issuer goes bankrupt. (Sure, you lose all your principal, but you're dead, so hey, maybe you don't care.) The insurance company essentially sells risk-tolerance. Other annuities aren't structured like this, and may be marketed towards non-retirees. They're usually not such a good deal. If they appear to be such a good deal, it may be an illusion. (Variable annuities in particular are hard to reason about without a good deal of knowledge about how the stock market behaves on a year-to-year basis: many of them have a maximum return as well as a minimum, and the stock market may pile up a lot of its returns into one year, so after a "crash and recovery" cycle you might end up behind the market instead of ahead.) Annuities are a form of safety. Safety can be very expensive. If you're investing your own money, consider whether you need that safety. You probably needn't worry quite so much about the issuer being crazy-fraudulent or Ponzi-esque: you should worry mostly about whether it looks better on paper than it is.
