What happens if I select a 1 prior rule for previous rate or coverage end?

Previous rate and coverage end rules that start with the phrase 1 prior terminate the rate or coverage period one day before the subsequent period starts.

For example, the previous coverage ends on the last day of the current month if the previous coverage end is 1 prior or quarter end and coverage start is First of next month.

If you don't specify a coverage start, or no next rate or coverage starts, then the second part of the rule goes into effect. In this case, the previous coverage would terminate at the end of the quarter. For example, the existing rate or coverage stops at the end of the quarter if a job termination life event with no associated rate start or coverage start occurs.
