(5)Regulation (EU) 2017/2402 sets qualifying criteria for STS securitisations in order to provide a harmonised definition of a higher quality securitisation product for Union capital markets. The ‘type 1 securitisation’ asset category in Delegated Regulation (EU) 2015/35 was created to achieve a similar objective for insurance and reinsurance undertakings, with comparable qualifying criteria. To ensure consistency and a level playing field on the securitisation market, the general provisions on the ‘type 1 securitisation’ asset category should be deleted from Delegated Regulation (EU) 2015/35 and reference should instead be made to the relevant provisions on STS securitisation laid down in Regulation (EU) 2017/2402. In order to avoid those amendments leading to adverse effects, transitional measures should be provided for with respect to existing assets falling within the ‘type 1 securitisation’ category.
