Look-Back Measurement Periods

The Look-Back Measurement Period List page lets you define one-to-many measurement periods for Affordable Care Act reporting. Use multiple measurement periods if you define different periods for different employee groups.

Measurement periods that already have been defined appear in a grid on the Look-Back Measurement Period List page. To edit a period, click the corresponding Code in the grid. To add a period to the grid, click the New button located in the bottom-left corner of the page. In either instance, the Look-Back Measurement Period page opens.
