DBRS Takes Rating Actions on Aggregator of Loans Backed by Assets 2015-1 Plc

RMBS
December 19, 2018

DBRS Ratings Limited (DBRS) took the following rating actions on the bonds issued by Aggregator of Loans Backed by Assets 2015-1 Plc (ALBA 2015-1 or the Issuer):

-- Class A Notes confirmed at AAA (sf)
-- Class B Notes confirmed at AA (high) (sf)
-- Class C Notes confirmed at A (high) (sf)
-- Class D Notes confirmed at BBB (sf)
-- Class E Notes upgraded to B (high) (sf) from B (sf)

The ratings on the Class A Notes, Class B Notes, Class C Notes, Class D Notes and Class E Notes (the Rated Notes) address the timely payment of interest and ultimate payment of principal on or before the legal final maturity date.

The rating actions follow an annual review of the transaction and are based on the following analytical considerations:

-- Portfolio performance, in terms of delinquencies, defaults and losses, as of the November 2018 payment date.
-- Portfolio default rate (PD), loss given default (LGD) and expected loss assumptions on the remaining receivables.
-- Current available credit enhancement (CE) to the notes to cover the expected losses at their respective rating levels.

ALBA 2015-1 closed in April 2015 and is a securitisation of U.K. non-conforming residential mortgages originated by Edeus Mortgage Creators Limited, GMAC-RFC Limited, Amber Homeloans Limited and Kensington Mortgage Company Limited. Pepper (UK) Limited is the Servicer of the mortgage portfolio.

PORTFOLIO PERFORMANCE AND ASSUMPTIONS
As of the November 2018 payment date, loans more than 90 days delinquent represented 2.8% of the outstanding collateral pool balance, up from 2.6% 12 months prior. Cumulative repossessions represented 4.4.% of the collateral balance at the transaction closing and cumulative losses were at 1.1%. DBRS conducted a loan-by-loan analysis of the remaining pool of receivables and updated its base case PD and LGD assumptions to 21.2% and 24.0%, respectively.

CREDIT ENHANCEMENT
As of the November 2018 payment date, CE to the Class A, B, C, D and E Notes increased to 51.8%, 41.2%, 30.7%, 21.6% and 11.0% from 47.1%, 37.5%, 27.8%, 19.6%, and 9.9%, respectively, 12 months prior. The sources of CE to each of the Rated Notes are their respective subordinated notes as well as overcollateralisation. Furthermore, the Rated Notes benefit from a Reserve Fund which provides liquidity and credit support. The Reserve Fund is currently at its target amount of GBP 8.2 million.

Citibank N.A., London Branch acts as the account bank for the transaction. Based on DBRS private rating of Citibank N.A., London Branch, the downgrade provisions outlined in the transaction documents, and structural mitigants, DBRS considers the risk arising from the exposure to the account bank to be consistent with the ratings assigned to the Class A Notes, as described in DBRS's "Legal Criteria for European Structured Finance Transactions" methodology.

Notes:
All figures are in British pound sterling unless otherwise noted.

The principal methodology applicable to the ratings is the “Master European Structured Finance Surveillance Methodology”.

DBRS has applied the principal methodology consistently and conducted a review of the transaction in accordance with the principal methodology.

A review of the transaction legal documents was not conducted as the legal documents have remained unchanged since the most recent rating action.

Other methodologies referenced in this transaction are listed at the end of this press release. These may be found on www.dbrs.com at: http://www.dbrs.com/about/methodologies.

The sources of data and information used for these rating actions include investor reports and loan- by-loan data provided by Citibank N.A., Agency and Trust.

DBRS did not rely upon third-party due diligence in order to conduct its analysis.

At the time of the initial ratings, DBRS was supplied with third-party assessments. However, this did not impact the rating analysis.

DBRS considers the data and information available to it for the purposes of providing these ratings to be of satisfactory quality.

DBRS does not audit or independently verify the data or information it receives in connection with the rating process.

The last rating action took place on 19 December 2017, when DBRS confirmed the ratings of the Class A and Class E Notes at AAA (sf) and B (sf), respectively and upgraded the ratings on the Class B, Class C and Class D Notes to AA (high) (sf), A (high) (sf) and BBB (sf), respectively.

The lead analyst responsibilities for this transaction have been transferred to Clare Wootton.
Information regarding DBRS ratings, including definitions, policies and methodologies is available at www.dbrs.com.

To assess the impact of changing the transaction parameters on the rating, DBRS considered the following stress scenarios as compared with the parameters used to determine the rating (the Base Case):

-- DBRS expected a lifetime base case PD and LGD for the pool based on a review of the current assets. Adverse changes to asset performance may cause stresses to base case assumptions and therefore have a negative effect on credit ratings.

-- The base case PD and LGD of the current pool of loans for the issuer are 21.17% and 24.0%, respectively.

-- The Risk Sensitivity overview below illustrates the ratings expected if the PD and LGD increase by a certain percentage over the base case assumption. For example, if the LGD increases by 50%, the rating on the Class A Notes would be expected to be at AAA (sf), assuming no change in the PD. If the PD increases by 50%, the rating on the Class A Notes would be expected to be at AA (high) (sf), assuming no change in the LGD. Furthermore, if both the PD and LGD increase by 50%, the rating on the Class A Notes would be expected to be at A (sf).

Class A Notes Risk Sensitivity:
-- 25% increase in LGD, expected rating of AAA (sf)

-- 50% increase in PD and 25% increase in LGD, expected rating of A (high) (sf)
