The following calculation shall be used when determining the allocation of voter registration costs:

1. (1) Determine the total voter registration costs for the entire fiscal year. Include amounts from the federal indirect cost allocation plan created in accordance with WAC 434-270-010 only if not using a flat 15 percent overhead factor.
2. (2) Subtract revenue attributable to voter registration services.
3. (3) Subtract any direct costs associated with a specific jurisdiction.
4. (4) Total the number of active and inactive registered voters in the county.
5. (5) Determine the number of active and inactive registered voters in each city and town. Subtract total active and inactive voters of every city and town from the total active and inactive voters ((4) of this section) in the county voter registration records to obtain those voters under county jurisdiction.
6. (6) Divide each jurisdiction's number of active and inactive registered voters ((4) of this section) by the total number of active and inactive registered voters ((5) of this section) to yield a percentage cost factor.
7. (7) Multiply the percentage cost factor ((6) of this section) by the voter registration costs to determine each jurisdiction's allocated cost.
8. (8) Add any direct costs, and the 15 percent overhead factor, if applicable, to each jurisdiction's allocated costs. This is the total amount due from each jurisdiction.
