Many institutions have established an internal retention policy that reflects its value as evidence in both civil and criminal actions. This policy is based upon the state's "statute of limitations" -- or that period of time in which an action must be brought to trial. For example, most banking crimes that are:
. Misdemeanors are generally one (1) year from the date of commission (e.g., petty theft, DWI and small-dollar NSF checks);
. Felonies are generally three (3) years from the date of commission (e.g., burglary, robbery and grand theft); and
. Embezzlements are generally three (3) years from the date of discovery.
Five (5) years is a safe e-mail retention period.
