DBRS Confirms Banco de Investimento Imobiliário S.A. Covered Bonds (Obrigações Hipotecárias - Mortgages) at A (high)

DBRS Ratings Limited (DBRS) confirmed its A (high) ratings on the Obrigações Hipotecárias (OH; the Portuguese legislative Covered Bonds) issued under the Banco de Investimento Imobiliário (BII or the Issuer) Covered Bonds programme (the Programme). The confirmation follows the completion of a full review of the Programme.

Banco Comercial Português (BCP) is the Reference Entity for the BII OH Programme as BCP is liable for BII’s obligations. BCP’s liability, which is irrevocable and unconditional, shall survive the end of the group relationship and last until satisfaction of all entitlements of the Issuer's creditors.

There is one series of OH outstanding under the Programme, with a nominal amount of EUR 895 million, which is entirely retained.

The ratings are based on the following analytical considerations:
-- A Covered Bonds Attachment Point (CBAP) of BBB, which is the Long-Term Critical Obligations Rating of BCP. BCP is the Reference Entity for the Programme.
-- A Legal and Structuring Framework (LSF) Assessment of “Average” associated with the Programme.
-- A Cover Pool Credit Assessment (CPCA) of BBB (low), which is the lowest CPCA in line with the LSF-Implied Likelihood (LSF-L).
-- An LSF-L of A (low).
-- A two-notch uplift for high recovery prospects.
-- A committed minimum overcollateralisation (OC) of 12.5%. DBRS gives full credit to such commitment in accordance with its principal methodology. Such a level is not subject to haircut as DBRS considers it to be persistent based on historically observed levels.

The transaction was analysed with the DBRS European Covered Bond Cash Flow tool. The main assumptions focused on the timing of defaults and recoveries of the assets, interest rate stresses and market value spreads to calculate liquidation values on the cover pool (CP).
Everything else being equal, a one-notch downgrade of the CBAP would lead to a one-notch downgrade of the LSF-L, resulting in a one-notch downgrade of the covered bonds rating. In addition, all else unchanged, the OH ratings would be downgraded if any of the following occurred: (1) the CPCA was downgraded below BBB (low); (2) the sovereign rating of the Republic of Portugal was downgraded below BBB (low); (3) the LSF assessment associated with the Programme was downgraded; (4) the quality of the CP and the level of OC were no longer sufficient to support a two-notch uplift for high recovery prospects; (5) the relative amortisation profile of OH and CP moved adversely; or (6) volatility in the financial markets caused the currently estimated market value spreads to increase.

The aggregated outstanding balance of the CP backing BII’s OH was EUR 1,022 million as of 31 December 2018 while the total amount of liabilities outstanding is EUR 895 million, yielding a current OC ratio of 14.2%. The Issuer has publicly committed to maintain an OC level of 12.5%.

As of 31 December 2018, the mortgage CP comprised 27,390 residential mortgages granted to individuals, with an average loan amount of EUR 32,738. The weighted-average (WA) current loan-to-value of the mortgages was 53.7% with a seasoning of 178 months. The CP is located mainly in Lisbon (37.2% by outstanding balance), Northern Portugal (41.7%) and Central Portugal (15.4%).

Of the loans in the portfolio, 95.9% pay a floating interest rate, indexed to Euribor, and 4.1% of the loans pay a fixed rate, while the only outstanding covered bond is floating rate.

The DBRS-calculated WA life of the mortgage assets is roughly 12 years based on a 0% prepayment rate, which is longer than the 0.9 years of WA life on the CB, not accounting for any maturity extension. This risk is mitigated by the OC available and by a long 20-year extendable maturity feature by which, should the Issuer default on its payment on the covered bonds at the expected maturity date, the covered bond maturity is automatically extended up to 20 years, with a pass-through structure until such date.

All CP assets and CB are denominated in euros. As such, investors are not currently exposed to any foreign-exchange risk.
