What this means for a producer

Every policy in this book has a public expiration date and a class of business. A producer with a competing market for electrical can work Mid-Century Insurance Co.'s renewals month by month: the chart above is the calendar, the county pages are the territory, and the licence record supplies the policy number and the date. Birdray adds what the record leaves out: the person to write to, what changed at the business, and the timing, then sends the first email from your inbox 60 days out.
