Thanks, Michael, and good afternoon to everyone. As Michael has already summarized our results for the second quarter and 6 months ended June 30, I would like to make a few comments on the various elements comprising those record earnings results.
Starting with the second quarter financial highlights. Net interest income was $6.1 million, an increase of $1.6 million in comparison to the prior year's second quarter. Net interest income benefited from our net interest margin, which increased from 3.47% -- or to 3.47% from 3.34% during the second quarter of 2013. Net interest margin remains relatively stable quarter-to-quarter and in comparison to the margin of 3.49% in the first quarter of 2014. Both the higher net interest income and the net interest margin were impacted primarily by our acquisition of Citizens Bank, resulting in an increase in the average interest-earning assets from $573.0 million in the second quarter of 2013 to $742.3 million during the second quarter of 2014. Looking at our provision, we provided $300,000 to the allowance for loan losses in the second quarter of 2014, as we did a year earlier.
Noninterest income increased $1.6 million to $4.1 million for the second quarter of 2014 as compared to the same period of 2013. Our gains on sales of loans reflected an increase of $967,000 for the second quarter of 2014 compared to a year earlier, to which our acquisition of Citizens Bank contributed. Other factors contributing to this increase were a $517,000 increase in fees and service charges and $129,000 in other noninterest income, primarily a result of the Citizens Bank acquisition.
Our first (sic) [second] quarter noninterest expenses increased by $2.2 million to $7.1 million on a linked-quarter basis, primarily resulting from the increased expenses related to operating 8 additional branch locations. These increases included a $1 million increase in compensation and benefits, $361,000 in occupancy and equipment, $332,000 in other expenses and $99,000 in data processing primarily related to the acquisition of Citizens Bank. We also reported an increase of $314,000 in amortization expense for the second quarter of 2014 as compared to the second quarter of 2013. Amortization expense was higher in comparison to the prior year in part due to the absence of a $212,000 valuation allowance reversal against our mortgage servicing rights portfolio, which we reported in the second quarter of 2013.
Moving on to discuss some financial highlights for the first half of 2014. Similar to my quarterly comments, primarily resulting from our acquisition of Citizens Bank, we experienced an increase in our net interest margin in comparison to the first 6 months of 2013, improving from 3.36% to 3.48% on a tax equivalent basis. Our acquisition of Citizens Bank helped increased our average interest-earning assets 29.9% from $569.2 million during the first 6 months of 2013 to $739.6 million during 2014. With the combination of these 2 changes, our net interest income increased $3.2 million to $12.1 million for the first 6 months of 2014, an increase of 36.8% compared to the same period of 2013.
We provided $450,000 to the allowance for loan loss in the first 6 months of 2014, which was a decline from a $600,000 provision during the first half of 2013. The second quarter provision of $300,000 represented an increase from the first quarter of 2014, when we provided $150,000 to the allowance for loan losses.
Noninterest income totaled $7.4 million for the first 6 months of 2014, an increase of $2.2 million or 42.6% in comparison to the same period of 2013. Consistent with my quarterly comments, this increase results primarily from increases of $1.1 million in gains on sale of loans due to higher volumes of loans sold in the secondary markets and $879,000 in fees and service charges received on deposit accounts and service fee income on 1-to-4 family residential real estate loan service for others. Additionally, other noninterest income increased $309,000, driven by higher lease revenue. Each of these increases were primarily attributable to our Citizens Bank acquisition.
Looking at our noninterest expense, we reported an increase of 42.7% or $4.2 million for the first 6 months of 2014 in comparison to the same period of 2013. This increase was the result of increases of $2.1 million in compensation and benefits, $772,000 in occupancy and equipment, $525,000 in noninterest expense, $395,000 in amortization and $251,000 in data processing.
Similar to my second quarter comments, these higher levels of expense in 2014 primarily reflected the operating costs relating to the 8 additional branches assumed in the Citizens Bank acquisition, while the comparison on amortization expense was impacted by the previously mentioned valuation allowance reversal against our mortgage servicing rights in the prior period.
As mentioned in our first quarter earnings conference call, due to the timing of the Citizens Bank acquisition, we continue to operate the Citizens locations on a separate computer system from Landmark until the close -- until close to the end of March 2014. Implementing a single computer system for all branches during the past quarter allowed us to obtain additional cost and operational efficiencies. Additionally, on May 16, we completed our previously announced plan to close one of our overlapping Fort Scott banking facilities.
To touch on a few balance sheet highlights, our total assets increased $7.3 million to $836 million at June 30, 2014 compared to $828.8 million at December 31, 2013. Our loan portfolio decreased slightly in the first 6 months to $412.7 million from $414.0 million at year-end 2013, while our investment securities increased to $322 million at June 30, 2014 from $305.5 million at December 31, 2013. Stockholders' equity increased by $6 million to $68.7 million at June 30, 2014, or a book value of $21.64 per share, compared to $62.7 million at year-end 2013, or a book value of $19.96 per share as slightly lower interest rates increased the fair value of our investment securities, resulting in an increase in accumulated other comprehensive income. Our consolidated and bank capital ratios continued to exceed the levels to be considered well capitalized as of June 30, 2014. The bank's leverage capital ratio was 8.3% at June 30, 2014, while the total risk-based capital ratio exceeded 14%.
I will now turn the call over to Brad Chindamo to review the highlights on our loan portfolio.
