If a payment is not made by the next billing cycle, Holmes-Wayne will mail a past due notice as part of the next month's bill that will be identified with a red note stating "friendly reminder your bill is past due" and previous bill information. The past due notice will include the standard ten (10) percent charge for the first $25.00 past due and two (2) percent charge for the remaining balance (above $25.00) that was not paid by the due date (20th or 5th of the respective billing cycles). A single day beyond the due date constitutes past due.
