Overpayments, credits, and duplicate payments.

When overpayments are made by insureds, agents or insurers, they may be recovered by offsets against amounts due from companies to the Fund. The offsets shall be recorded on Form 216 with minus signs or brackets to distinguish them from debits and shall be accompanied by evidence in support of refunds resulting from premium reductions under § 242.5(a)(1) (relating to adjustment of surcharge). Surcharge credits of amounts less than $10 may be waived in accordance with the insurer’s policy relative to small return premiums.
