(l) | Securitisation exposure: Definition of attachment point A and detachment point D |
(i) | The attachment point A represents the threshold at which losses within the underlying pool would first be allocated to the securitisation exposure. The input A, (which is a decimal value between zero and one), equals the greater of – |
(A) | zero; and |
(B) | the ratio of |
(i) | the outstanding balance of all underlying assets in the securitisation minus the outstanding balance of all tranches that rank senior to the tranche that contains the securitisation exposure of the bank (including the exposure itself) C |
divided by
(ii) | the outstanding balance of all underlying assets in the securitisation. |
(iii) | For the calculation of input (A) and input (D). |
(A) | overcollateralization and funded reserve accounts must be recognised as tranches; and |
(B) | the assets forming these reserve accounts must be recognised as underlying assets. Only the loss-absorbing part of the funded reserve accounts that provide credit enhancement can be recognised as tranches and underlying assets. Unfunded reserve accounts, such as those to be funded from future receipts from the underlying exposures (e.g. unrealised excess spread) and assets that do not provide credit enhancement like pure liquidity support, currency or interest-rate swaps, or cash collateral accounts related to these instruments must not be included in the calculation of (A) and (D). |
(C) | Banks must take into consideration the economic substance of the transaction and apply these definitions conservatively in the light of the structure. |
