All monthly bills generate the first Saturday of each month for the next month’s premium due. Below is an example of how the billing process works:

• The bill for October premium is generated on the 1^st Saturday in September and payment will be due October 1.
• If full payment is not received by the October premium due date, 10/1, a second billing notice generates on the 1^st Saturday in October. This billing notice will include the November premium amount in addition to the October amount due.
• October’s premium payment must be received by The Caltech Retiree Service Center no later than October 31^st in order to keep coverage active.
