Net income for the nine months ended September 30, 2011 was $2,801,000, a $978,000, or 53.6% increase from the $1,823,000 earned during the same period of 2010.  Year-to-date diluted earnings per share were $1.69 in 2011 compared to $1.16 in 2010.

During the 2011 third quarter, net interest income increased $778,000 from the third quarter of 2010.  The provision for loan losses in the third quarter of 2011 stood at $920,000, which was $306,000 less than the same period of 2010.  Total non-interest expense increased $164,000, while non-interest income during the third quarter of 2011 was $9,000 below that reported in the same period of 2010.   

Annualized returns on average equity ("ROE") and average assets ("ROA") for the 2011 third quarter were 11.11% and 0.66%, respectively, compared with 4.54% and 0.29% for the third quarter of 2010.  The nine month period ending September 30, 2011 saw ROE and ROA of 9.82% and 0.59%, respectively.  The comparable period 2010 results were 6.31% and 0.41%.

"We are pleased to report continued strong financial results for the third quarter and year-to-date periods, especially in light of an economic environment that continues to be extremely challenging," stated Thomas G. Caldwell, President and Chief Executive Officer, "We have continued to enhance our profitability by following solid banking fundamentals."

"Obviously, we are pleased with the improvement in our net interest margin.  This has been achieved through managing our cost of funding, while properly pricing quality loans.  With the Fed's actions to hold short-term rates low into mid-2013, while also introducing Operation Twist, we are working to maintain a solid net interest margin so as to remain a strong community bank."

"Our focus remains on delivering excellent customer service, offering a dynamic suite of products, and maximizing value for our shareholders," Caldwell concluded.

Asset Quality

For the nine months ended September 30, 2011, the provision for loan losses increased 5.5% to $2,485,000, which compares to the $2,355,000 for the same period of 2010.  For the three month period ended September 30, 2011, the provision for loan losses was $920,000.  During the same period of 2010, the provision was $1,226,000.  Donald L. Stacy, Chief Financial Officer of Middlefield Banc Corp. stated "Our asset quality numbers are a reflection of the economic uncertainty that continues on a national scale.  This continued weakness remains a concern and warrants measures to provide for the sound operation of our company."

Stacy continued, "We are, however, finding that our problem credits have been properly identified as the increase in our non-performing assets has stabilized.  Expectations are that an improvement in our asset quality numbers will be seen as we move into 2012." 

The increased loan loss provision has significantly outpaced loan charge-offs.  Net charge-offs for the third quarter of 2011 were 0.10% of average loans, while the ratio for the first nine months of 2011 was 0.30%.  The ratio of the allowance for loan losses to total loans stood at 1.95% at September 30, 2011, compared to the 1.63% reported at September 30, 2010.  Based upon the evaluation of the allowance for loan losses, it is the belief of management that, as of September 30, 2011, the allowance for loan losses was adequate and reflects probable incurred losses within the portfolio. 

Net Interest Income

Net Interest Income totaled $15.5 million for the first nine months of 2011.  This represents an increase of 17.1 % from the $13.3 million reported for the comparable period of 2010.  The improvement in net interest income was primarily generated by an increase in both average earning assets and net interest margin.  Interest income on investment securities increased $0.2 million while the company experienced a decrease in interest expense on deposits of $1.4 million.  Continued action by the Federal Open Market Committee to hold interest rates at historic low levels has provided the company the opportunity to continue to lower funding costs.  The pricing environment for new loans remains highly competitive within the company's markets.  Interest earnings on loans did increase $0.5 million from the year ago period.  This increase in earnings on loans was achieved in spite of the level of non-performing loans. 

For the three month period ended September 30, 2011 compared to the same period of 2010, Middlefield's net interest income was up 16.9%, or $0.8 million.  The positive variance was based on an increase of $0.2 million from the loan portfolio, coupled with a decrease of $0.1 million from the investment portfolio and a decrease in deposit costs of $0.6 million. 

The net interest margin for the first nine months of 2011 was 3.69%, representing an increase from the 2010 same period result of 3.39%.  The yield on earning assets dropped 18 basis points, while the cost of interest-bearing liabilities experienced a decrease of 51 basis points. 

Non-Interest Income and Operating Expenses

Non-interest income decreased $9,000 for the three-month period of 2011 from the comparable 2010 period.  Lower service charges on deposit accounts are attributable to Federal regulatory changes to overdraft rules.  For the first nine months of 2011, deposit services charges were $22,000 below the same period of 2010.  This was offset by an increase in investment services income as well as the collection of rents on OREO properties. 

Non-interest expense of $3,906,000 for the third quarter of 2011 was 4.4%, or $164,000 higher than the third quarter of 2010.  Increases in salaries and employee benefits of $211,000 are primarily attributable to staff additions, as well as an increase in health insurance costs.  Cost associated with the administration and liquidation of delinquent loans, OREO properties and foreclosures were the primary contributors to higher 2011 non-interest expenses. 

For the nine month period of 2011, total operating costs were $775,000, or 7.0%, above those of the 2010 comparable period.  Contributing to the increase were salaries and employee benefits and increased other expenses.  The higher 2011 other expense figure is primarily attributable to  costs directly related to loan quality issues, including loan and other real estate owned expense in the company's non-bank subsidiary, EMORECO, Inc. 

Balance Sheet Growth

The company's total assets as of September 30, 2011 stood at $660.7 million, an increase of 4.5% over the $632.2 million in total assets reported at December 31, 2010.  Net loans at September 30, 2011, were $381.0 million, up $16.7 million, or 4.6%, over the $366.3 million reported at December 31, 2010.  Total deposits at the end of the third quarter 2011 were $587.2 million, or 3.9% greater than the deposit level of $565.3 million at December 31, 2010. 

The investment portfolio, which is entirely classified as available for sale, stood at $204.5 million at September 30, 2011.  This figure represented growth within that portfolio of $2.7 million from the prior year-end.  Stockholders' equity at September 30, 2011, was $46.7 million.  Book value per share as of September 30, 2011, was $26.59.
