Basis of Calculation Hierarchy

To easily review the basis of calculation for multiple DBAs, review the basis of calculation hierarchy. This hierarchy graphically illustrates the reporting relationships between PDBAs, even those DBAs that are based on multiple DBAs. For example, a typical hierarchy for retirement savings plan DBAs shows:

  • The employer match DBA is based on the employee contribution DBA.

  • The employee contribution DBA is based on pay types 1 through 999.
