LOS ANGELES, July 20, 2016 /PRNewswire/ -- Cathay General Bancorp (the "Company", NASDAQ: CATY), the holding company for Cathay Bank, today announced net income of $34.8 million, or $0.44 per share, for the second quarter of 2016.

FINANCIAL PERFORMANCE

SECOND QUARTER HIGHLIGHTS

• On July 8, 2016, we signed a Stock Purchase Agreement to acquire SinoPac Bancorp, the U.S. holding company for Far East National Bank, for $340 million subject to certain adjustments.

"We are very excited about the transaction to acquire Far East National Bank and the additional scale it adds to our franchise in Los Angeles, our home market, as well as Orange County, San Francisco, and Silicon Valley and the opportunity to deploy a portion of our capital to generate strong returns. Cathay Bank and Far East National Bank share similar attributes and business values, and we look forward to servicing customers of Far East National Bank and hope they will enjoy the additional products and services that Cathay Bank has to offer," commented Dunson Cheng, Chairman of the Board, Chief Executive Officer, and President of the Company.

"Our loan growth continued to be solid. Total loans increased $162 million for the quarter, or 6% annualized, to $10.5 billion at June 30, 2016, compared to $10.4 billion at March 31, 2016. Our year to date loan growth was $356 million, or 7% annualized," concluded Dunson Cheng.

SECOND QUARTER INCOME STATEMENT REVIEW

Net income for the quarter ended June 30, 2016, was $34.8 million, a decrease of $10.4 million, or 22.9%, compared to net income of $45.2 million for the same quarter a year ago. Diluted earnings per share for the quarter ended June 30, 2016, was $0.44 compared to $0.56 for the same quarter a year ago.

Return on average stockholders' equity was 8.00% and return on average assets was 1.07% for the quarter ended June 30, 2016, compared to a return on average stockholders' equity of 10.93% and a return on average assets of 1.56% for the same quarter a year ago. The decrease is primarily due to the $20.8 million increase in amortization of investments in alternative energy partnerships.

Net interest income before provision for credit losses

Net interest income before provision for credit losses increased $7.0 million, or 7.4%, to $101.8 million during the second quarter of 2016 compared to $94.8 million during the same quarter a year ago. The increase was due primarily to the increase in interest income from loans, partially offset by the increase in interest expense from time deposits.

The net interest margin was 3.38% for the second quarter of 2016 compared to 3.51% for the second quarter of 2015. The decrease in the net interest margin was due to a combination of the impact of the special Federal Home Loan Bank dividend and higher interest recoveries in the prior year and higher interest bearing deposits at the Federal Reserve Bank this year. The decrease in the net interest margin for the second quarter of 2016 from 3.42% in the first quarter of 2016, was primarily due to the higher interest bearing deposits at the Federal Reserve Bank and higher interest recoveries and lower excess cash balances in the first quarter.

For the second quarter of 2016, the yield on average interest-earning assets was 4.05%, the cost of funds on average interest-bearing liabilities was 0.89%, and the cost of interest-bearing deposits was 0.70%. In comparison, for the second quarter of 2015, the yield on average interest-earning assets was 4.16%, the cost of funds on average interest-bearing liabilities was 0.87%, and the cost of interest-bearing deposits was 0.65%. The net interest spread, defined as the difference between the yield on average interest-earning assets and the cost of funds on average interest-bearing liabilities, was 3.16% for the quarter ended June 30, 2016, compared to 3.29% for the same quarter a year ago.

Reversal for credit losses

Reversal for credit losses was $5.2 million for the second quarter of 2016 compared to $2.2 million for the second quarter of 2015. The reversal for credit losses was based on the review of the appropriateness of the allowance for loan losses at June 30, 2016. The provision or reversal for credit losses represents the charge against or benefit toward current earnings that is determined by management, through a credit review process, as the amount needed to establish an allowance that management believes to be sufficient to absorb credit losses inherent in the Company's loan portfolio, including unfunded commitments. The following table summarizes the charge-offs and recoveries for the periods indicated:

Non-interest income

Non-interest income, which includes revenues from depository service fees, letters of credit commissions, securities gains (losses), gains (losses) on loan sales, wire transfer fees, and other sources of fee income, was $9.1 million for the second quarter of 2016, an increase of $3.5 million, or 61.2%, compared to $5.6 million for the second quarter of 2015, which was primarily due to $3.3 million of net securities losses recorded in the second quarter of 2015.

Non-interest expense

Non-interest expense increased $21.3 million, or 44.7%, to $68.9 million in the second quarter of 2016 compared to $47.6 million in the same quarter a year ago. The increase in non-interest expense in the second quarter of 2016 was primarily due to increases of $20.8 million in amortization of investments in alternative energy partnerships as a result of rapid installation of solar systems from our investment made in March 2016. The efficiency ratio was 62.15% in the second quarter of 2016 compared to 47.41% for the same quarter a year ago.

Income taxes

The effective tax rate for the second quarter of 2016 was 26.1% compared to 17.7% for the second quarter of 2015. The effective tax rate includes the impact of the utilization of low income housing tax credits and alternative energy tax credits.

BALANCE SHEET REVIEW

Gross loans, excluding loans held for sale, were $10.5 billion at June 30, 2016, an increase of $359.6 million, or 3.5%, from $10.2 billion at December 31, 2015, primarily due to increases of $230.0 million, or 4.3%, in commercial mortgage loans, $214.5 million, or 11.1%, in residential mortgage loans, and $40.3 million, or 9.1%, in real estate construction loans partially offset by decreases of $128.8 million, or 5.6%, in commercial loans. The loan balances and composition at June 30, 2016, compared to December 31, 2015, and to June 30, 2015, are presented below:

ASSET QUALITY REVIEW

At June 30, 2016, total non-accrual loans were $53.1 million, a decrease of $13.0 million, or 19.6%, from $66.1 million at June 30, 2015, and an increase of $1.0 million, or 1.9%, from $52.1 million at December 31, 2015.

The allowance for loan losses was $122.9 million and the allowance for off-balance sheet unfunded credit commitments was $2.1 million at June 30, 2016, which represented the amount believed by management to be appropriate to absorb credit losses inherent in the loan portfolio, including unfunded commitments. The $122.9 million allowance for loan losses at June 30, 2016, decreased $16.1 million, or 11.5%, from $139.0 million at December 31, 2015. The allowance for loan losses represented 1.17% of period-end gross loans, excluding loans held for sale, and 231.4% of non-performing loans at June 30, 2016. The comparable ratios were 1.37% of period-end gross loans, excluding loans held for sale, and 266.6% of non-performing loans at December 31, 2015. The changes in non-performing assets and troubled debt restructurings at June 30, 2016, compared to December 31, 2015, and to June 30, 2015, are highlighted below:

Troubled debt restructurings on accrual status totaled $74.7 million at June 30, 2016, compared to $81.7 million at December 31, 2015. These loans are classified as troubled debt restructurings as a result of granting a concession to borrowers. Although these loan modifications are considered troubled debt restructurings under Accounting Standard Codification 310-40 and Accounting Standard Update 2011-02, these loans have demonstrated sustained performance under the modified terms. The sustained performance considered by management includes the periods prior to the modification if the prior performance met or exceeded the modified terms as well as cash paid to set up interest reserves.

The ratio of non-performing assets, excluding non-accrual loans held for sale, to total assets was 0.6% at June 30, 2016, compared to 0.6% at December 31, 2015. Total non-performing assets increased $2.8 million, or 3.5%, to $79.6 million at June 30, 2016, compared to $76.8 million at December 31, 2015, primarily due to an increase of $1.0 million, or 1.9%, in non-accrual loans and a $1.7 million increase, or 6.9%, in other real estate owned.

CAPITAL ADEQUACY REVIEW

At June 30, 2016, the Company's common equity Tier 1 capital ratio of 12.77%, Tier 1 risk-based capital ratio of 13.84%, total risk-based capital ratio of 15.02%, and Tier 1 leverage capital ratio of 11.80%, calculated under the Basel III capital rules, continue to place the Company in the "well capitalized" category for regulatory purposes, which is defined as institutions with a common equity tier 1 capital ratio equal to or greater than 6.5%, a Tier 1 risk-based capital ratio equal to or greater than 8%, a total risk-based capital ratio equal to or greater than 10%, and a Tier 1 leverage capital ratio equal to or greater than 5%.
