DBRS Morningstar Confirms Rating on Volta IV Electricity Receivables Securitisation

October 19, 2020

DBRS Ratings GmbH (DBRS Morningstar) confirmed its A (sf) rating on the Senior Notes issued by Volta IV Electricity Receivables Securitisation (Volta IV).

The confirmation follows an annual review of the transaction and is based on the following analytical considerations:

-- The linkage between the performance of the sovereign and the performance of the securities issued by Volta IV.
-- No adverse change of the legal or regulatory framework is expected.
-- The transaction is not exposed to the credit risk of any specific entity.
-- Current economic environment and an assessment of sustainable performance, as a result of the Coronavirus Disease (COVID-19) pandemic.

The transaction is a static securitisation of Portuguese electricity tariff receivables (Credit Rights) assigned to Volta IV by EDP – Serviço Universal, S.A. – NR (EDP-SU). Pursuant to the Portuguese Decree-law 29/2006 (as subsequently amended and republished), EDP-SU has the right to recover any amounts arising from the difference between the costs of acquiring electricity under the special regime generation according to administrative prices and the sale price of the respective electricity valued according to market prices. The Credit Rights are paid entirely by Portuguese electricity consumers through their inclusion in the tariffs on a permanent basis as a component of the Global Use of System Tariff, or total rate per unit paid by end consumers. The transaction closed in July 2016.

Based on DBRS Morningstar’s “Rating Portuguese Electricity Tariff Securitisations” methodology, the ratings on the Senior Note issued by Volta IV are limited to a maximum of two-notch increase above the current local currency sovereign rating of the Republic of Portugal (Portugal). DBRS Morningstar’s Sovereign Group confirmed Portugal’s Long-Term Foreign and Local Currency Issuer Ratings at BBB (high) with a Stable trend in September 2020, two notches below the current rating of the Senior Notes.

Citibank N.A., London Branch acts as Account Bank for the transaction. Based on the DBRS Morningstar private rating, the downgrade provisions outlined in the transactions documents, and structural mitigants, DBRS Morningstar considers the risk arising from the exposure to Citibank N.A. to be consistent with the rating assigned to the Senior Notes, as described in DBRS Morningstar’s “Legal Criteria for European Structured Finance Transactions” methodology.

The Coronavirus Disease (COVID-19) and the resulting isolation measures have caused an economic contraction, leading to sharp increases in unemployment rates and income reductions for many borrowers. DBRS Morningstar anticipates that delinquencies may arise in the coming months for many ABS transactions, some meaningfully. The ratings are based on additional analysis and, where appropriate, additional adjustments to expected performance as a result of the global efforts to contain the spread of the coronavirus.

DBRS Morningstar concludes that for the Senior Notes:
-- A hypothetical downgrade of the sovereign rating of Portugal by one notch, ceteris paribus, would lead to a decrease in the rating of the Senior Notes to A (low) (sf).
