Why is Washington National Insurance sending out checks for return of Premium?

Washington National Ins. Co. offers supplemental Cancer, Heart/Stroke, and Accidental Injury Insurance with a Return of Premium rider on it, or referred to as a Cash Return Rider in some states. The policies pay back all premiums paid in, above and beyond any claims paid out after the customer keeps the policy in force for 20 or 25 years (depending on your state), or age 75, whichever comes first. It is not necessary to claim the return, once the policy has reached its maturity date, the policyholder is contacted to notify them that the return is being processed.
