AI Summary of Article 257 Determination of tranche maturity (MT)

This section outlines the criteria for measuring the maturity of a tranche in a securitisation context. Institutions may choose to calculate tranche maturity (MT) using either the weighted average maturity of contractual payments or by the final legal maturity, with established floors and caps set between 1 and 5 years.

Additionally, where exposure to potential losses exists under a contract, the maturity must account for the contract duration combined with the longest maturity of the underlying exposures, particularly considering revolving exposures. The EBA is tasked with monitoring practices in this domain and is to issue guidelines by the end of 2019.

Where an institution may become exposed to potential losses from the underlying exposures by virtue of contract, the institution shall determine the maturity of the securitisation position by taking into account the maturity of the contract plus the longest maturity of such underlying exposures. For revolving exposures, the longest contractually possible remaining maturity of the exposure that might be added during the revolving period shall apply.
