On June 27 , 2016 we learned that contact sheets , which are documents kept in a system used for sales purposes , had been accessed and possibly viewed for unauthorized purposes . We immediately began an investigation and brought in outside experts . We determined the unauthorized access occurred between March and June of 2016 . While there is no indication that the information in this system has been used fraudulently , we needed to let you know that your information was in this system . The information on the contact sheets that were exposed included name , address , and phone number . For some people it also included date of birth and limited health notes , such as a doctor name , health condition , or medication name . For a small number of individuals it may have also included Social Security number . ;
