"A sustained deterioration in HNB's credit profile relative to 'AA(lka)'-rated peers would add downward pressure to its rating."
HNB's net interest margin was 6.0 percent in the 2009 financial year - well above the local licensed commercial banks (LCB) sector average of 5.3 percent, the rating agency said.
HNB's pre-tax return on assets (ROA) increased to 3.0 percent in 2009 from 2.5 percent the year before due to non-recurring items (NRI), which pertain to recoveries from a large NPL (non-performing loan), an investment, and value-added tax.
After adjusting for these NRI, HNB's adjusted pre-tax ROA was 2.8 percent in FY09 - still comparatively good in the local context, Fitch said.
At end-June 2010 (H110), about 40 percent of HNB's loan book was corporate loans, with retail and consumer loans and small and medium enterprise
