The maturity of the credit protection shall be determined in accordance with Chapter 4; (b) an originator institution shall ignore any maturity mismatch in calculating risk-weighted exposure amounts for tranches appearing pursuant to this Section with a risk weighting of 1 250 %. For all other tranches, the maturity mismatch treatment set out in Chapter 4 shall be applied in accordance with the following formula: where: RW* risk-weighted exposure amounts for the purposes of Article 92(3)(a); RWAss risk-weighted exposure amounts for exposures if they had not been securitised, calculated on a pro-rata basis; RWSP risk-weighted exposure amounts calculated under Article 249 if there was no maturity mismatch; T maturity of the underlying exposures expressed in years; t maturity of credit protection. expressed in years; t* 0,25.
