True/False: PCGs only sum values. They do not subtract values.

• A. False
• B. Not necessarily
• C. Depends
• D. True

Answer: (D)

PCG sums are used to accumulate amounts from the payroll components you include in the group. They don’t perform a separate subtraction operation; they simply add the values of the components. If a component has a negative amount, that negative value reduces the total when the group is totaled, which is how subtraction is represented within the summing process. So the statement that PCGs only sum values and do not subtract values is accurate. If you need a deduction to reduce a total, you model it by using a negative amount for that component so the overall sum decreases accordingly.
