Interest earned by the county on Departmental funds shall be considered as other income to reduce total expenditures in arriving at eligible expenditures for Departmental participation. However, since interest is considered a legitimate revenue of the county, it is available for use by the county to increase the level of service provided. Interest cannot be used to offset the county's matching share, to fund nonchildren and youth related services, or county general expenses.
