Partial-period inputs control whether incomplete first, interim, and final units are excluded, used as reported, or annualized.

• First / Interim / Final Partial Period: Sets the treatment for each type of incomplete unit: exclude, include without adjustment, or include after annualization.
• Treat Partial Periods as Full Units: Counts an included partial period as one full unit when measuring the averaging period.
• Period Rounding: Rounds the measured length of a partial unit when it is not treated as a full unit.
• Calculation Method: Defines the day- or month-based method used to measure the partial-period fraction.
• Use separate rules for short-service employees: Activates the short-service inputs below.
• Sum all earnings and divide by total period: Develops the short-service average from total earnings divided by the combined measured period.
• Short-Service First / Interim / Final: Sets separate partial-period treatment for participants who meet the short-service definition.
• Include Short-Service Partial Periods as Full Units: Counts each included short-service partial period as one full unit.
• Short-Service Base: Service Definition used to measure whether the participant has short service.
• Short-Service Threshold: Number of units below which the separate short-service rules apply.
