Its non-performing loans (NPLs) overdue for three months had risen to 2.7 percent in the first half of the 2013 financial year, up from 1.7 percent at the end of the 2012 financial year.

Its gross NPL ratio over six months was below 0.5 percent, which Fitch said was better than similarly rated peers.
