Territorial Savings Bank earned a $5.1 million second-quarter profit that was up slightly from a year before and largely derived from Hawaii home mortgage lending.

The local bank, through parent Territorial Bancorp Inc., eked out a 2% income gain, or $100,000 more than last year’s second quarter.

Territorial said its income from loan interest rose to $16 million in the three months ended June 30 from $14.9 million a year earlier. But expenses, including interest paid on customer deposits, rose by about as much.

Allan Kitagawa, company chairman and CEO, said in a statement that the bank’s financial results were strong.

“We were able to increase our total loans and deposits while maintaining good asset quality,” he said.

Territorial, Hawaii’s fifth-largest bank, generates more than 95% of its loans from residential lending.

Loans receivable for the bank edged up 2% to $1.60 billion from $1.57 billion in the comparable quarter.

Deposits increased 1% to $1.65 billion from $1.63 billion. Assets grew 1% to $2.09 billion from $2.07 billion.

The company’s board of directors approved a quarterly cash dividend of 22 cents per share that is slated to be paid Aug. 22 to stockholders of record as of Thursday.
