The Board shall establish a trust account to hold premium payments accepted from qualified plan enrollees and small employers by the Exchange on behalf of a carrier under contract or other agreement. The trust account may be used only to hold a premium payment until the Exchange transmits the premium payment to the carrier on whose behalf the Exchange accepted the premium payment. The Exchange shall maintain separate records of account for each carrier on whose behalf it accepts premium payments. The payment of a premium by an enrollee or a small employer to the Exchange is deemed to be a payment to the carrier on whose behalf the Exchange accepted the premium payment.
