Article 256 6.

For the purposes of calculating the attachment points (A) and detachment points (D) of a synthetic securitisation, the originator institution of the securitisation shall treat the exposure value of the securitisation position corresponding to synthetic excess spread referred to in point (e) of Article 248(1) as a tranche, and adjust the attachment points (A) and detachment points (D) of the other tranches it retains by adding that exposure value to the outstanding balance of the pool of underlying exposures in the securitisation. Institutions other than the originator institution shall not make this adjustment.
