All changes input to the payroll master file are identified in the "employee change report" (from Payroll Processing Software) on a semi-monthly basis and this is reviewed by the Manager Global Payroll Services (GPS) (There is not evidence of this review). A "base-line" audit is performed by the Manager GPS each pay period. This audit reconciles HR Management System and Payroll Processing Software information and every change to base pay is accounted for from one period to the next. The Manager of Financial Services reviews and approves the "base-line" audit.
