Fitch Rates NAB's Series 13-1 Covered Bonds 'AAA'; Outlook Stable

(The following statement was released by the rating agency) SYDNEY, June 07 (Fitch) Fitch Ratings has assigned National Australia Bank's (NAB, AA-/Stable/F1+) Series 13-1 issue of EUR750m mortgage covered bonds a 'AAA' rating with a Stable Outlook. The fixed-rate bond is due in June 2025 and benefits from a 12-month extendable maturity. KEY RATING DRIVERS The rating is based on NAB's Long-Term Issuer Default Rating (IDR) of 'AA-', a Discontinuity Cap (D-Cap) of 3 (moderate high) and an asset percentage (AP) of 87%, which is equivalent to Fitch's breakeven AP for a 'AAA' rating, supporting a 'AA' rating on a probability of default (PD) basis and a 'AAA' rating after giving credit for recoveries. The Outlook on the covered bonds reflects the Stable Outlook on NAB's IDR. The driver of the D-Cap is the high risk assessment for liquidity gap and systemic risk. This reflects the agency's view of the liquidity gap mitigants in the form of a three-month interest reserve fund, the 12-month pre-maturity test on the hard bullet covered bonds and the 12-month extendable maturity on the soft bullet covered bonds. The D-Cap of 3, when combined with the institution's IDR and recovery uplift, continues to support a 'AAA' rating on the covered bonds. As of end-April 2013, the cover pool consisted of 45,506 loans secured by first-ranking mortgages of Australian residential properties with a total outstanding balance of AUD12.3bn and AUD1.3bn of cash. The portfolio is wholly made up of full documentation loans which have a weighted average current loan-to-value ratio of 58.9%, and a weighted average seasoning of 34.1 months. Floating rate loans comprise 91.9% and fixed rate loans 8.1% of the cover pool by balance. The mortgage portfolio is geographically distributed across Australia's states, with the largest concentrations being in New South Wales (35.2%) and Victoria (30.6%). In a 'AAA' scenario, Fitch has calculated a weighted average frequency of foreclosure for the cover assets of 8.4%, and a weighted average recovery rate of 58.2%. The agency's mortgage default analysis is based on its Australian residential mortgage criteria. Maturity mismatches are significant, with the weighted-average residual life of the assets at 16.8 years and of the liabilities at 6.7 years. RATING SENSITIVITIES The 'AAA' rating would be vulnerable to a downgrade if the issuer's Long-Term IDR is downgraded by three or more notches; if the D-Cap falls by more than two categories; or if the programme's AP rises above the breakeven AP of 87.0%.
