Most BIS policies are subject to audit.  Soon after your policy expiration date, you will be required to complete our Mandatory Audit Questionnaire online or by mail.  The brief two-page audit is what allows us to calculate the final policy premium.  Non-compliance with policy audit will result in an estimated audit invoice based on our best estimate of policy exposures and will, among other possible actions, prevent us from offering future renewal terms.  Your cooperation is appreciated.
