Accordingly, certain financial information and footnotes have been omitted or condensed. The consolidated condensed financial statements include the accounts of the Company, and its wholly owned banking subsidiary Columbia Bank (the “Bank”). All intercompany transactions and accounts have been eliminated in consolidation. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of the results for the interim periods presented have been included. The results of operations for the nine months ended September 30, 2011 are not necessarily indicative of results to be anticipated for the year ending December 31, 2011. The accompanying interim unaudited consolidated condensed financial statements should be read in conjunction with the financial statements and related notes contained in the Company’s 2010 Annual Report on Form 10-K. Significant Accounting Policies The significant accounting policies used in preparation of our consolidated financial statements are disclosed in our 2010 Annual Report on Form 10-K. Other than as discussed below, there have not been any changes in our significant accounting policies compared to those contained in our 2010 10-K disclosure for the year ended December 31, 2010. Discounted Loans Discounted loans are the loans acquired through acquisitions or direct purchase for which we believe a credit loss is not probable at the time of acquisition. Discounted loans are included on the consolidated condensed balance sheet in the “Loans, excluding covered loans” line item. Generally these loans as a group do not exhibit pervasive indications of declines in credit quality from the time of initial origination. Discounted loans are recorded at fair value at the time of acquisition. The estimate of fair value includes a discount related to credit risk and a premium or discount related to interest rates that is recorded for each loan separately. Interest income is recognized through the accrual of interest at the loans' stated rates, plus accretion or amortization of the discount or premium recorded at acquisition. Credit losses for discounted loans are recorded through the provision for loan losses using a similar methodology as originated loans. However, the amount of expected incurred loss of unpaid principal must be compared to the net carrying value which includes the remaining discount or premium. Currently none of our discounted loans are covered by indemnification agreements with the FDIC.
