ACNB Corporation, headquartered in Gettysburg, Pennsylvania, provides banking, insurance, and financial services to businesses and consumers through its wholly-owned subsidiaries, ACNB Bank and Russell Insurance Group, Inc. (RIG). The Bank engages in full-service commercial and consumer banking and trust services through its nineteen retail banking locations in Adams, Cumberland and York Counties, Pennsylvania. There are also two loan production offices situated in York and Franklin Counties, Pennsylvania.

RIG is a full-service insurance agency, based in Westminster, Maryland. The agency offers a broad range of property and casualty, life, and health insurance to both commercial and individual clients. In 2008, due to an agency acquisition, a second location of RIG was established in Germantown, Maryland.

The Corporation, along with seven other banks, entered into a joint venture to form BankersRe Insurance Group, SPC (formerly Pennbanks Insurance Co., SPC), an offshore reinsurance company. Each participating entity owns an insurance cell through which its premiums and losses from credit life, health and accident insurance are funded. Each entity is responsible for the activity in its respective cell. The financial activity for the insurance cell has been reported in the consolidated financial statements and is not material to the consolidated financial statements.

The Corporation's primary source of revenue is interest income on loans and investment securities and fee income on its products and services. Expenses consist of interest expense on deposits and borrowed funds, provisions for loan losses, and other operating expenses.

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly ACNB Corporation's financial position as of September 30, 2011 and 2010, and the results of operations, changes in stockholders' equity, and cash flows for the three and nine months ended September 30, 2011 and 2010. All such adjustments are of a normal recurring nature.

The accounting policies followed by the Corporation are set forth in Note A to the Corporation's consolidated financial statements in the 2010 ACNB Corporation Annual Report on Form 10-K, filed with the SEC on March 11, 2011. It is suggested that the consolidated financial statements contained herein be read in conjunction with the consolidated financial statements and notes included in the Corporation's Annual Report on Form 10-K. The results of operations for the three and nine month periods ended September 30, 2011, are not necessarily indicative of the results to be expected for the full year.

The Corporation has evaluated events and transactions occurring subsequent to the balance sheet date of September 30, 2011, for items that should potentially be recognized or disclosed in the consolidated financial statements. The evaluation was conducted through the date these consolidated financial statements were issued.
