If the title agency contracts between a title insurer and the title insurer's appointed title agents provide for a split of premiums between the title insurer and the title insurance agent, the title insurer must file premium rate schedules using supporting data and information that are consistent with that contractual premium split. The title insurer's base rates should be consistent with its actual contractual split of premiums between the title insurer and its agents. The title insurer's use of more than one premium split with its agents, if any, must be addressed through the filing of rating rules that specify the situations in which other premium splits are used and the adjustments that result from their use.
