How do I know if I am After the Fact (ATF) or LAG?

You are paid “After the Fact” if the Pay End Date on your Pay Statement is about 15 days before the Advice Date. See below where the pay end date is 8/15/22, which is about 15 days before the Advice Date 9/2/22.

You are paid “LAG” if the Pay End Date on your Pay Statement within 5 days of the Advice Date. See below where the pay end date is 8/31/22, which is within 5 days of the Advice Date 9/2/22.
