Part 246 (“Regulation RR”) and (b) (i) Article 405(1) of Regulation (EU) No. 575/2013 of the European Parliament and of the Council of 26 June 2013, as supplemented by Commission Delegated Regulation (EU) No. 625/2014; (ii) Article 51(1) of the Commission Delegated Regulation (EU) No. 231/2013 and (iii) Article 254(2) of the Commission Delegated Regulation (EU No. 2015/35), each as in effect as of the Closing Date, together with any guidance published in relation thereto including any regulatory and/or implementing technical standards in effect as of the date hereof (collectively, the “EU Retention Rules”).

Santander Consumer has not changed the manner in which it retains the Retained Interest, except in accordance with Regulation RR and the EU Retention Rules.

On February 8, 2018, Santander Consumer sold all of the Class E Notes to third party purchasers. Other than the sale of the Class E Notes, there was no material change in Santander Consumer’s, or an affiliate of Santander Consumer’s, interest in any securities issued by the issuer resulting from the purchase, sale or other acquisition or disposition of securities between the Closing Date and the last day of the period covered by this report.
