BOWIE, Md., Aug. 10, 2011 (GLOBE NEWSWIRE) -- James W. Cornelsen, President and Chief Executive Officer of Old Line Bancshares, Inc. (Nasdaq:OLBK), the parent company of Old Line Bank, reported that net income available to common stockholders increased $710,996 or 71.48% for the six months ended June 30, 2011 to $1.7 million from $994,631 for the six month period ended June 30, 2010. Earnings per basic and diluted common share were $0.30 for the six months ended June 30, 2011 and $0.26 for the same period in 2010.

For the three month period ended June 30, 2011, net income available to common stockholders was $1.2 million or $0.17 per basic and diluted common share. This was $652,848 or 123.16% higher than the same period in 2010.

The acquisition of Maryland Bankcorp, Inc., on April 1, 2011, was the primary contributor to the increase in net income available to common stockholders as well as the increases in net interest income, non-interest revenue, and non-interest expense during the six and three month periods ended June 30, 2011. 

Mr. Cornelsen said "I am extremely pleased to report an increase in net income, a growth in loans and an improvement in the net interest margin and that we were able to accomplish this while seamlessly converting all of the former MB&T customers to Old Line Bank with overall deposit retention in excess of 97%. During the quarter, we also continued to successfully manage the company to produce continued profitability, organic loan and deposit growth and maintain stellar credit quality metrics in a difficult operating environment." Mr. Cornelsen also said that "it's important to note that profitability for the quarter and the six month period were negatively impacted by the integration and merger expenses of $377,214 for the three month period, $467,724 for the six month period and a non-recurring impairment on equity securities of $122,500 during the three and six month periods. Although we have a few additional merger and integration expenses that we will recognize in the 3^rd quarter of 2011, we expect that these expenses will be significantly less than those incurred in the 2^nd quarter of 2011. We have also identified additional areas within the former MB&T non-interest expense structure that we expect will provide expense reductions during the remainder of 2011 and beyond."

Mr. Cornelsen continued, "As expected, the net interest margin increased 91 basis points in the second quarter of 2011 compared to last year's second quarter and 65 basis points from the first quarter of 2011. This was primarily attributable to the acquisition of MB&T which contributed approximately $93.0 million in non-interest bearing deposits. These deposits are a primary source of funding for our investment and loan portfolios and should continue to enhance our net interest margin."

Relative to our peers, our asset quality continues to remain strong even with the addition of the MB&T loan portfolio. We did not experience any increase in non-performing assets that we held prior to the acquisition (legacy loans). In accordance with accounting for business combinations, we have recorded the acquired assets and liabilities at their estimated fair value on April 1, 2011, the acquisition date. At April 1, 2011, the determination of the fair value of the loans acquired (acquired loans) caused an approximately $24.3 million write down in the value of certain loans and other real estate owned, that we assigned to an accretable or non-accretable balance. We will recognize the $2.0 million accretable balance as interest income over the remaining term of the loans. We will recognize the $22.3 million non-accretable balance as the borrowers repay the loans or we sell the other real estate owned. These decreases to the loan portfolio were offset by an approximately $3.1 million fair value adjustment based on current interest rates of similar loans that we will recognize over the remaining life of the loans. The accretion of these adjustments favorably impacted our net interest income by approximately $393,000 during the three and six month periods. We currently have proactive efforts underway to collect payments on many of these loans or to develop satisfactory resolutions.

As part of the fair value process, we were also required by current accounting principles to eliminate the allowance for loan and lease losses associated with the acquired loans which caused the allowance for loan losses to decline to 0.45% of total gross loans from 0.82% at December 31, 2010. We decreased our provision for loan losses $120,000 and $40,000 for the three and six month periods ended June 30, 2011, respectively, because our legacy loan portfolio's asset quality remained stable, we experienced minimal growth in the legacy portfolio and we believe that recoveries of $72,407 along with the $50,000 provision were sufficient to support any inherent risk in the loan portfolio. Our legacy non-performing assets remain statistically low at 0.41% and all borrowers with loans past due between 30-89 days at quarter end submitted payments subsequent to quarter end. Based on our history, internal analysis, the ratio of non-performing assets, and the satisfactory historical performance of the loan portfolio, management believes the allowance continues to appropriately reflect the inherent risk of loss in our portfolio and the current economic climate.
