Summary of Significant Accounting Policies	(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) Basis of Presentation: The accompanying unaudited condensed consolidated financial statements for Timberland Bancorp, Inc. ("Company") were prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with instructions for Form 10-Q and, therefore, do not include all disclosures necessary for a complete presentation of financial condition, results of operations, and cash flows in conformity with GAAP. However, all adjustments which are in the opinion of management, necessary for a fair presentation of the interim condensed consolidated financial statements have been included. All such adjustments are of a normal recurring nature. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended September 30, 2011 ("2011 Form 10-K"). The unaudited condensed consolidated results of operations for the three months ended December 31, 2011 are not necessarily indicative of the results that may be expected for the entire fiscal year. (b) Principles of Consolidation: The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Timberland Bank ("Bank"), and the Bank's wholly-owned subsidiary, Timberland Service Corp. All significant inter-company balances have been eliminated in consolidation. (c) Operating Segment: The Company has one reportable operating segment which is defined as community banking in western Washington under the operating name, "Timberland Bank." (d) The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. (e) Certain prior period amounts have been reclassified to conform to the December 31, 2011 presentation with no change to net income or total shareholders' equity previously reported.
