The FDIC is the nation’s largest bank regulatory agency. Banks are graded on a 1 to 5 scale of safety and soundness by their regulators. Over the past 25 years, there have been many banks that have made the troubled bank list.

But the other 13 percent that do fail are either sold or have a portion of their assets and deposits bought by other banks.”]
