DBRS Morningstar Upgrades and Confirms Ratings on BEST 2010 B.V.

RMBS
September 10, 2021

DBRS Ratings GmbH (DBRS Morningstar) upgraded and confirmed its ratings of the bonds issued by BEST 2010 B.V. (the Issuer), as follows:

-- Senior Class A Mortgage-Backed Floating Rate Notes confirmed at AAA (sf)
-- Mezzanine Class B Mortgage-Backed Floating Rate Notes upgraded to AA (high) (sf) from AA (sf)
-- Junior Class C Mortgage-Backed Floating Rate Notes upgraded to BBB (high) (sf) from BBB (low) (sf)

The ratings address the timely payment of interest and the ultimate payment of principal on or before the legal final maturity date in October 2099.

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 July 2021 payment date;
-- Portfolio default rate (PD), loss given default (LGD), and expected loss assumptions on the current pool of receivables;
-- Current available credit enhancement to the notes to cover the expected losses at their respective rating levels;
-- No revolving termination events have occurred so far; and
-- Current economic environment and an assessment of sustainable performance, as a result of the Coronavirus Disease (COVID-19) pandemic.

The transaction is a securitisation of Dutch residential mortgages originated by local offices of Coöperatieve Rabobank U.A. (with a DBRS Morningstar Long-Term Critical Obligations Rating (COR) of AA (high)) and Rabohypotheekbank N.V. Servicing of the mortgages is conducted by the relevant local cooperative or Service Centrum Financieren (a centralised service centre, which is part of the Group). The transaction has a revolving period scheduled to end on the October 2021 payment date. During the revolving period, the Issuer is allowed to replenish the repaid receivables subject to the mortgage loan criteria and substitution criteria.

The substitution criteria, which allows the continuation of replenishment of receivables during the revolving period, stipulates that the 60 days’ arrears ratio is less than 2.25% (currently at 0.06%), the realised loss ratio is less than 0.60% of the original portfolio balance (currently at 0.1%), the principal deficiency ledger is equal to zero, and that there have been no drawings on the reserve account. All criteria are currently met.

PORTFOLIO PERFORMANCE
As of the July 2021 payment date, loans that were two to three months in arrears represented 0.01% of the outstanding portfolio balance, stable since July 2020; the 90+ delinquency ratio was 0.03%, down from 0.05% in the same period; the cumulative default ratio was 0.1%, and the cumulative loss ratio was 0.1%.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
DBRS Morningstar conducted a loan-by-loan analysis of the current pool of receivables and considered a base case PD and LGD assumptions, including coronavirus-related adjustments, of 2.1% and 9.0%, respectively, down from 2.9% and 14.1%, at the previous annual review in September 2020. The improved portfolio assumptions resulted from using the current portfolio instead of the worst-case portfolio composition (typical for the revolving transactions), given the scheduled end of the revolving period on the next payment date in October 2021. The improved portfolio assumptions are driving the rating upgrades of the Class B and Class C Notes.

CREDIT ENHANCEMENT
As of the July 2021 payment date, credit enhancement to the Senior Class A Mortgage-Backed Floating Rate Notes was 7.3%, up from 7.0% at the DBRS Morningstar initial rating. Credit enhancement to the Mezzanine Class B Mortgage-Backed Floating Rate Notes was 4.3%, up from 4.0% at the DBRS Morningstar initial rating. Credit enhancement to the Junior Class C Mortgage-Backed Floating Rate Notes was 1.3%, up from 1.0% at the DBRS Morningstar initial rating. Because of the revolving period, credit enhancements to the notes remain unchanged since the latest DBRS Morningstar rating action.

The transaction benefits from a reserve fund of EUR 650 million and a liquidity facility of EUR 1,010 million, which can be drawn upon to cover interest shortfalls should the reserve account be insufficient. The liquidity facility is currently undrawn.

Coöperatieve Rabobank U.A. acts as the account bank for the transaction. Based on the account bank’s reference rating of AA, which is one notch below its DBRS Morningstar Long-Term COR of AA (high), the downgrade provisions outlined in the transaction documents, and other mitigating factors inherent in the transaction structure, DBRS Morningstar considers the risk arising from the exposure to the account bank to be consistent with the rating assigned to the Senior Class A Mortgage-Backed Floating Rate Notes, as described in DBRS Morningstar's "Legal Criteria for European Structured Finance Transactions" methodology.

Coöperatieve Rabobank U.A. also acts as the swap counterparty for the transaction and its COR of AA (high) is above the First Rating Threshold as described in DBRS Morningstar's "Derivative Criteria for European Structured Finance Transactions" methodology.

DBRS Morningstar analysed the transaction structure in Intex.

The coronavirus and the resulting isolation measures have caused an immediate economic contraction, leading in some cases to increases in unemployment rates and income reductions for many borrowers. DBRS Morningstar anticipates that delinquencies may continue to increase in the coming months for many RMBS transactions. The ratings are based on additional analysis to expected performance as a result of the global efforts to contain the spread of the coronavirus. For this transaction, DBRS Morningstar increased the expected default rate for self-employed borrowers and conducted additional sensitivity analysis to determine that the transaction benefits from sufficient liquidity support to withstand potential high levels of payment holidays in the portfolio. As of the July 2021 payment date, no loans in the portfolio were under coronavirus-related payment moratoria.

Information regarding DBRS Morningstar ratings, including definitions, policies, and methodologies is available at www.dbrsmorningstar.com.

To assess the impact of changing the transaction parameters on the rating, DBRS Morningstar considered the following stress scenarios as compared with the parameters used to determine the rating (the Base Case):
-- DBRS Morningstar 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 2.1% and 9.0%, 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 Senior Class A Mortgage-Backed Floating Rate Notes would be expected to remain at AAA (sf), assuming no change in the PD. If the PD increases by 50%, the rating on the Senior Class A Mortgage-Backed Floating Rate Notes would be expected to remain at AAA (sf), assuming no change in the LGD. Furthermore, if both the PD and LGD increase by 50%, the rating on the Senior Class A Mortgage-Backed Floating Rate Notes would be expected to fall to AA (high) (sf).

Senior Class A Mortgage-Backed Floating Rate Notes Risk Sensitivity:
-- 25% increase in LGD, expected rating of AAA (sf)
-- 50% increase in LGD, expected rating of AAA (sf)
-- 25% increase in PD, expected rating of AAA (sf)

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

Mezzanine Class B Mortgage-Backed Floating Rate Notes Risk Sensitivity:
-- 25% increase in LGD, expected rating of AA (high) (sf)
-- 50% increase in LGD, expected rating of AA (high) (sf)
-- 25% increase in PD, expected rating of AA (high) (sf)
-- 50% increase in PD, expected rating of AA (sf)
-- 25% increase in PD and 25% increase in LGD, expected rating of AA (high) (sf)

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