Credit-enhancing interest-only strip
Credit-enhancing interest-only strip (CEIO) means an on-balance sheet asset that, in form or in substance:
(1) Represents a contractual right to receive some or all of the interest and no more than a minimal amount of principal due on the underlying exposures of a securitization; and
(2) Exposes the holder to credit risk directly or indirectly associated with the underlying exposures that exceeds a pro rata share of the holder's claim on the underlying exposures, whether through subordination provisions or other credit-enhancement techniques.
