Note 1. General

In the opinion of management, the accompanying unaudited financial statements contain all adjustments (consisting of only normal recurring accruals) necessary to present fairly the financial position at September 30, 2012 and December 31, 2011, the results of operations and comprehensive income for the three and nine months ended September 30, 2012 and 2011, and changes in shareholders' equity and cash flows for the nine months ended September 30, 2012 and 2011, in accordance with accounting principles generally accepted in the United States of America. The statements should be read in conjunction with the Notes to Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2011 (the "2011 Form 10-K") of Middleburg Financial Corporation (the "Company"). The results of operations for the three and nine month periods ended September 30, 2012 are not necessarily indicative of the results to be expected for the full year.

In preparing these financial statements, management has evaluated subsequent events and transactions for potential recognition or disclosure through the date these financial statements were issued. Management has concluded there were no additional material subsequent events to be disclosed.

Certain amounts in the 2011 consolidated financial statements have been reclassified to conform to the 2012 presentation. Commissions and fees paid on the origination of mortgages held for sale and commissions paid on investments sales have been netted against the related revenue amounts for these sources of revenue for both 2012 and 2011. Management considers the net presentation to more accurately reflect the net contribution to consolidated net income of the mortgage and wealth management segments.
