I want to thank everyone involved in our company for helping to make it the success it has become. Thanks again for your support of our company.
Let me turn over our discussion to Asylbek Osmonov, our Chief Financial Officer, to discuss some of the specific financial results we achieve. Asylbek?
Asylbek Osmonov: Thank you, Mr. Zalman. Net interest income before provision for credit losses for the three months ended June 30th, 2019, was $154.8 million compared to $161.8 million for the same period in 2018, a decrease of $7 million or 4.3%. The decrease was primarily due to a lower loan discount accretion in the second quarter of 2019, and higher than normal collection on nonaccrual loans in the prior year.
The net interest margin on a tax equivalent basis was 3.16% for the three months ended June 30th, 2019, compared to 3.28% for the same period in 2018, and 3.2% for the quarter ended March 31st, 2019. Excluding purchase accounting adjustments and the higher than normal collection on nonaccrual loans last year, the core net interest margin for the quarter ended June 30th, 2019, was 3.14%, compared to 3.12% for the same period in 2018, and 3.16% for the quarter ended March 31st, 2019.
Noninterest income was $30 million for the three months ended June 30th, 2019, compared to $28.4 million for the same period in 2018. Noninterest expense for the three months ended June 30th, 2019, was $80.8 million, compared to $83.6 million for the same period in 2018.
The efficiency ratio was 43.74% for the three months ended June 30th, 2019, compared to 43.95% for the same period in 2018, and 42.94% for the three months ended March 31st, 2019.
The bond portfolio metrics at 6/30/2019 showed a weighted average life of 3.64 years, an effective duration of 3.25, and projected annual cash flows of approximately $1.9 billion.
And with that, let me turn over the presentation to Tim Timanus for some detail on loans and credit — asset quality.
Tim Timanus: Thank you, Asylbek. Our nonperforming assets at quarter end June 30th, 2019, totaled $41.558 million or 39 basis points of loans and other real estate, compared to $40.883 million or 39 basis points at March 31st, 2019. This is an increase of $675,000 from March 31st, 2019.
