TEXT-Fitch upgrades Unnim Banc mortgage covered bonds to 'A'

5 Min Read

Oct 5 - Fitch Ratings has upgraded Unnim Banc S.A.'s (Unnim Banc,
'BBB+'/Negative/'F2') mortgage covered bonds (Cedulas Hipotecarias or CH) to 'A'
with a Negative Outlook from 'BBB+' and removed them from Rating Watch Positive

The rating actions follow the finalisation of the annual review and the
resolution of the RWP which was placed on the CH on 18 September 2012 (see
"Fitch Revises Rating Watch on Unnim's CH to Positive" at www.fitchratings.com).

The CH rating is mainly based on Unnim's Long-term Issuer Default Rating (IDR)
of 'BBB+', the Discontinuity Cap (D-Cap) assessment of 0 (full discontinuity
risk) and the overcollateralisation (OC) ratio of 83% that Fitch takes into
account within its analysis.

The 'A' rating on Unnim?s CHs would be vulnerable to a downgrade if the issuer's
IDR was downgraded, or the programme OC drops below Fitch's estimated breakeven
OC ratio of 72% in a 'A' stress environment. The Negative Outlook on Unnim's IDR
drives the Negative Outlook on the CH.

As of July 2012, Unnim Banc's total CH amounted to EUR6.7bn and were secured
over the bank's total mortgage cover pool of EUR12.9bn, resulting in a total OC
of 92%. Unnim Banc publicly states its best efforts to maintain an OC of at
least 90%. However, Fitch judges this not to be a contractual obligation, and
consequently applies a 10% OC haircut on the lowest OC observed of the last 12
months (92%) to derive a total OC credited level of 83% within its analysis.
This 10% haircut is introduced in line with the agency's covered bond criteria
for 'F2' rated issuers in the absence of contractual minimum levels of OCs.

Fitch assigned a D-Cap of 0 to Unnim's covered bonds, which implies full
discontinuity upon the issuer default. This continuity risk analysis is driven
by the liquidity gap and systemic risk assessment for Spanish covered bonds
issued by banks rated above the sovereign ('BBB'/Negative/'F2'). In Fitch's
opinion, there is a lack of specific protection against liquidity shortfalls
post assumed issuer insolvency and only intervention by the Spanish authorities
would avoid a default on the covered bonds in this scenario (see "Fitch Assigns
Spanish Mortgage Covered Bond Programmes Outlooks and D-Caps" dated 11 September
2012 at www.fitchratings.com).

Fitch considers Unnim's CH to be materially exposed to interest rate and
maturity mismatches, as most of the cover assets are linked to floating rates
(81% of the cover pool) and have a weighted-average (WA) residual life of 13.1
years, which compares to most CH being linked to fixed rates and a shorter WA
residual life of 5.5 years. In terms of portfolio loss analysis, and based on
the cover pool composition and historical performance data analysed, Fitch
estimates a total cover pool WA default rate of 43.5%, a WA recovery rate of
33.4% and a WA loss rate of 29% in a 'A' stress environment.

The Fitch estimated breakeven OC will be affected, among others, by the profile
of the cover assets relative to outstanding covered bonds, which can change over
time, even in the absence of new issuances. Therefore it cannot be assumed to
remain stable.

Additional information is available on www.fitchratings.com. The ratings above
were solicited by, or on behalf of, the issuer, and therefore, Fitch has been
compensated for the provision of the ratings.
