STATEMENT OF OPERATIONS

Net interest income before provision for losses on loans and loan commitments totaled $39.2 million for the second quarter of 2016, an increase of 0.7% from $38.9 million for the first quarter of 2016 and an increase of 4.5% from $37.5 million for the second quarter of 2015. Relative to the first quarter of 2016, an increase in average earning assets was partially offset by a slight decline in net interest margin.

Net interest margin was 3.53% for the second quarter of 2016, compared to 3.54% for the first quarter of 2016, and 3.59% for the second quarter of 2015. The decrease in net interest margin compared to the first quarter of 2016 was primarily attributable to an increase in the cost of deposits.

Loan yields were 4.62% for the second quarter of 2016, compared to 4.61% for the first quarter of 2016, and 4.78% for the second quarter of 2015. The increase in loan yields for the second quarter of 2016, compared to the first quarter of 2016, was primarily due to an increase in yield on commercial real estate loans.

The total cost of deposits was 0.64% for the second quarter of 2016, compared to 0.62% for the first quarter of 2016, and 0.61% for the second quarter of 2015. Compared to the first quarter of 2016, the increase in the total cost of deposits was attributable to increases in rates in all deposit categories.

Non-Interest Income

Total non-interest income was $9.7 million for the second quarter of 2016, compared to $8.5 million for the first quarter of 2016, and $11.3 million for the second quarter of 2015.

The Company recognized $3.4 million in gain on sale of loans during the second quarter of 2016, compared to $2.7 million for the first quarter of 2016, and $4.2 million for the second quarter of 2015. The increase in gain on sale of loans for the second quarter of 2016, compared to the previous quarter, was due to an increase in sales of Small Business Administration (“SBA”) and residential mortgage loans. Gain on sale of loans in the second quarter of 2016 consisted of $2.0 million in gains on sales of SBA loans and $1.4 million in gains on sales of residential mortgage loans.

Other non-interest income totaled $3.5 million for the second quarter of 2016, compared to $2.9 million for the first quarter of 2016 and $4.0 million for the second quarter of 2015. The increase in other non-interest income, compared to the first quarter of 2016, was due to an increase in loan servicing income and income recorded from the fair value change of servicing assets.

Non-Interest Expense

Total non-interest expense was $21.6 million for the second quarter of 2016, compared with $26.7 million for the first quarter of 2016, and $24.7 million for the second quarter of 2015. Non-interest expense in the second quarter of 2016 included $527,000 in merger-related costs consisting mostly of consulting and legal expenses related to the proposed merger of equals with BBCN.

Total salaries and employee benefits expense was $13.1 million for the second quarter of 2016, compared to $14.8 million for the first quarter of 2016, and $14.2 million for the second quarter of 2015. The decrease in salaries and employee benefits for the second quarter of 2016, compared to the previous quarter, was primarily due to lower payroll taxes, bonus accrual expense, and stock-based compensation expense.

Other non-interest expense was $3.4 million for the second quarter of 2016, compared with $6.9 million for the first quarter of 2016, and $6.2 million for the second quarter of 2015.
