Results of Operations

Net interest income before provision for loan losses for the second quarter of 2018 was $10.0 million, an increase of $428 thousand, or 4.5%, compared to $9.6 million for the first quarter of 2018, primarily due to an $882 thousand increase in interest income, partially offset by a $454 thousand increase in interest expense.  

Interest income from the contractual interest rates on loans increased $861 thousand, or 8.5%, during the second quarter, reflecting a 5.4% increase in average loans, including loans held for sale, and a 10 basis point increase in the average contractual interest rate from the increase in Fed funds rate in June 2018 of 25 basis points.   The amount of discount accretion on SBA loans decreased $86 thousand during the quarter due to a reduction in SBA loan payoffs during the second quarter of 2018.  The reported interest income on loans, net of SBA discount accretions and other components, increased $822 thousand during the quarter.  

The reported interest income and yield on our loan portfolio are impacted by a number of components, including changes in the average contractual interest rate earned on loans and the amount of discount accretion on SBA loans.  The following table reconciles the contractual interest income and yield on our loan portfolio to the reported interest income and yield for the periods indicated.

Interest expense for the second quarter of 2018 increased $454 thousand compared to the first quarter of 2018, due to an increase of $26.8 million, or 5.0% in average balance of interest-bearing liabilities and an increase of 25 basis points in average cost of interest-bearing liabilities, primarily due to the aforementioned increase in Fed funds rate.  

Net interest margin for the second quarter of 2018 decreased 10 basis points to 4.46% from 4.56% for the first quarter of 2018, primarily due to the increase in the cost of interest-bearing liabilities, partially offset by the increase in the reported yield on loans.

Net interest income before provision for loan losses for the second quarter of 2018 increased $1.4 million, or 16.2%, to $10.0 million, compared to $8.6 million for the second quarter of 2017, primarily due to a $2.5 million or 25.6%, increase in interest income, partially offset by an increase of $1.1 million in interest expense.

The increase in interest expense was due to a 26.1% increase in average interest-bearing liabilities and a 57 basis point increase in the cost of interest-bearing liabilities.  The increases in the average yields on loans and average cost of deposits were primarily due to cumulative market rate increases by the Federal Reserve of 75 basis points through three rate hikes of 25 basis points in each of December 2017, March 2018 and June 2018.
