Basis of Presentation

1)	Basis of Presentation
	In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of Glacier Bancorp, Inc.’s (the “Company”) financial condition as of June 30, 2011, stockholders’ equity and comprehensive income for the six months ended June 30, 2011, the results of operations for the three and six month periods ended June 30, 2011 and 2010, and cash flows for the six months ended June 30, 2011 and 2010. The condensed consolidated statement of financial condition and statement of stockholders’ equity and comprehensive income of the Company as of and for the year ended December 31, 2010 have been derived from the audited consolidated statements of the Company as of that date.
	The accompanying condensed consolidated financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010. Operating results for the three and six months ended June 30, 2011 are not necessarily indicative of the results anticipated for the year ending December 31, 2011. Certain reclassifications have been made to the 2010 financial statements to conform to the 2011 presentation.
	Material estimates that are particularly susceptible to significant change include the determination of the allowance for loan and lease losses (“ALLL” or “allowance”) and the valuations related to investments and real estate acquired in connection with foreclosures or in satisfaction of loans. In connection with the determination of the ALLL and other real estate valuation estimates, management obtains independent appraisals (new or updated) for significant items. Estimates relating to investments are obtained from independent parties. Estimates relating to business combinations are determined based on internal calculations using significant independent party inputs and independent party valuations.
