SINGAPORE (April 30): United Overseas Bank reported 1Q2015 earnings of $801 million, up 1.6% from a year earlier, with a rise in impairment charges and operating costs partly offsetting higher fee income and loan growth.

Impairment charges were higher across markets in Southeast Asia, up 7.6% to $169 million, on the back of a larger loan book.

UOB's non-performing loan ratio edged up to 1.2% from 1.1%.

Net interest income increased 8.3% to $1.2 billion as loans grew across most sectors and regions.

Net interest margin inched up to 1.76% from 1.73% on improved loan pricing and higher securities yield.

Non-interest income grew 17.5% to $755 million on higher contributions from all business lines.

Total operating expenses were also higher, up 12.9% at $852 million, driven by staff and IT expenses.

Profit contributions from associates fell to $4 million from $43 million due to a divestment gain in 1Q2014.

Compared to 4Q2014, UOB's March-quarter earnings rose 1.9%.

UOB shares ended 2.2% lower at $24.42 yesterday.
