The ACA Period is populated by UBACA only when a look-back measurement period is selected for the employee. The options are:
*Administration Period
*Initial Period
**For new hires, starting on the fourth full calendar month to the end of the Lookback month
*Non Assessment Period
**For new hires, their first partial month and the first three full calendar months
*Stability Period
**A full time employee is put into a stability period and will remain so for a year, based upon the date that is stamped in IEEI.  To remove them from a stability period, clear out this date.  When an employee is in a stability period, no computations are made with regard to hours worked or wage – as the previous month’s values will be used.
*Standard measurement Period
