Section 939Aof the Dodd-Frank Act requires the Commission to remove certain references to credit ratings from its regulations and to substitute such standards of creditworthiness as the Commission determines to be appropriate.  The Division is considering recommending that the Commission adopt proposed amendments to eliminate the exceptions for investment grade non-convertible debt, non-convertible preferred, and asset-backed securities (as rated by at least one Nationally Recognized Statistical Rating Organization) from Rules 101 and 102 of Regulation M and replace the exception in Rule 101 with alternative standards one based on distance to default using a Structural Credit Risk Model for non-convertible debt and non-convertible preferred debt, and one based on SF-3 shelf registration for asset-backed securities.
