(2)A pool of underlying exposures should only be considered homogenous where it contains exposures of a single asset type. Distinct asset types should therefore be identified so that exposures may be assigned accordingly. Market practice has already identified well established asset types to determine the homogeneity of a given pool of underlying exposures. However, in order to ensure that financial innovation is not limited and existing market practice is not hindered, particular pools of underlying exposures that do not correspond to one of those well-established asset types should also be allowed to be considered a single asset type on the basis of the internal methodologies and parameters consistently applied by the originator or sponsor. It is also possible that one exposure would allow for an assignment to more than one asset type. Notwithstanding, all underlying exposures in a particular securitisation should belong to the same asset type.
