Notes to Unaudited Condensed Consolidated Financial Statements

General

Glacier Bancorp, Inc. (the “Company”) is a Montana corporation headquartered in Kalispell, Montana. The Company is a regional multi-bank holding company that provides a full range of banking services to individual and corporate customers in Montana, Idaho, Wyoming, Colorado, Utah and Washington through its bank subsidiaries (collectively referred to hereafter as the “Banks”). The bank subsidiaries are subject to competition from other financial service providers. The bank subsidiaries are also subject to the regulations of certain government agencies and undergo periodic examinations by those regulatory authorities.

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 the Company’s financial condition as of September 30, 2011, stockholders’ equity and comprehensive income for the nine months ended September 30, 2011, the results of operations for the three and nine month periods ended September 30, 2011 and 2010, and cash flows for the nine months ended September 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 nine months ended September 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: 1) the determination of the allowance for loan and lease losses (“ALLL” or “allowance”), 2) the valuations related to investments and real estate acquired in connection with foreclosures or in satisfaction of loans, and 3) the evaluation of goodwill impairment. 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 the evaluation of goodwill impairment are determined based on independent party valuations and internal calculations using significant independent party inputs.

Principles of Consolidation

As of September 30, 2011, the Company is the parent holding company (“Parent”) for eleven independent wholly-owned community bank subsidiaries: Glacier Bank (“Glacier”), First Security Bank of Missoula (“First Security”), Western Security Bank (“Western”), Valley Bank of Helena (“Valley”), Big Sky Western Bank (“Big Sky”), and First Bank of Montana (“First Bank-MT”), all located in Montana; Mountain West Bank (“Mountain West”) and Citizens Community Bank (“Citizens”) located in Idaho; 1st Bank (“1st Bank”) and First Bank of Wyoming, formerly First National Bank & Trust, (“First Bank-WY”) located in Wyoming; and Bank of the San Juans (“San Juans”) located in Colorado. Effective June 30, 2011, First Bank-WY changed from a national bank charter to a Wyoming bank charter. All significant inter-company transactions have been eliminated in consolidation.

In 2010, the Company formed a wholly-owned subsidiary, GBCI Other Real Estate (“GORE”), to isolate certain bank foreclosed properties for legal protection and administrative purposes. The foreclosed properties were sold to GORE from bank subsidiaries at fair market value and properties remaining are currently held for sale.

The Company owns seven trust subsidiaries, Glacier Capital Trust II (“Glacier Trust II”), Glacier Capital Trust III (“Glacier Trust III”), Glacier Capital Trust IV (“Glacier Trust IV”), Citizens (ID) Statutory Trust I (“Citizens Trust I”), Bank of the San Juans Bancorporation Trust I (“San Juans Trust I”), First Company Statutory Trust 2001 (“First Co Trust 01”) and First Company Statutory Trust 2003 (“First Co Trust 03”) for the purpose of issuing trust preferred securities. The trust subsidiaries are not consolidated into the Company’s financial statements.

The following abbreviated organizational chart illustrates the Company’s various relationships as of September 30, 2011:

Variable Interest Entities

A variable interest entity (“VIE”) exists 1) when either the entity’s total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support from other parties, or 2) the entity has equity investors that cannot make significant decisions about the entity’s operations or that do not absorb their proportionate share of the expected losses or receive the expected returns of the entity. In addition, a VIE must be consolidated by the Company if it is deemed to be the primary beneficiary of the VIE, which is the party involved with the VIE that will absorb a majority of the expected losses, receive a majority of the expected residual returns, or both. The VIEs are regularly monitored to determine if any reconsideration events have occurred that could cause its primary beneficiary status to change.

The Company has equity investments in Certified Development Entities (“CDE”) which have received allocations of new markets tax credits (“NMTC”). The Company also has equity investments in low-income housing tax credit (“LIHTC”) partnerships. The CDEs and the LIHTC partnerships are VIEs. The underlying activities of the VIEs are community development projects designed primarily to promote community welfare, such as economic rehabilitation and development of low-income areas by providing housing, services, or jobs for residents. The maximum exposure to loss in the VIEs is the amount of equity invested and credit extended by the Company. However, the Company has credit protection in the form of indemnification agreements, guarantees, and collateral arrangements. The Company has evaluated the variable interests held by the Company in each CDE (NMTC) and LIHTC partnership investment and determined that the Company continues to be the primary beneficiary of such VIEs. As the primary beneficiary of these VIEs, the entities’ assets, liabilities, and results of operations are included in the Company’s consolidated financial statements. The following table summarizes the carrying amounts of the entities’ assets and liabilities included in the Company’s consolidated financial statements at September 30, 2011 and December 31, 2010:

Amounts presented in the table above are adjusted for intercompany eliminations. All assets presented can be used only to settle obligations of the consolidated VIEs and all liabilities presented consist of liabilities for which creditors and other beneficial interest holders therein have no recourse to the general credit of the Company.

Impact of Recent Authoritative Accounting Guidance

The Accounting Standards Codification ^TM (“ASC”) is the Financial Accounting Standards Board’s (“FASB”) officially recognized source of authoritative U.S. generally accepted accounting principles (“GAAP”) applicable to all public and non-public non-governmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under the authority of the federal securities laws are also sources of authoritative GAAP for SEC registrants. All other accounting literature is considered non-authoritative.

In September 2011, FASB issued amendments to FASB ASC Topic 350, Intangibles—Goodwill and Other . The amendments provide an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If the entity concludes it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. The amendments are effective prospectively during interim and annual periods beginning after December 15, 2011 and early adoption is permitted. The Company is currently evaluating the impact of the adoption of this amendment, but does not expect it to have a material effect on the Company’s financial position or results of operations.

In June 2011, FASB issued amendments to FASB ASC Topic 220, Comprehensive Income . The amendments provide an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement or in two separate but consecutive statements. The amendments are effective retrospectively during interim and annual periods beginning after December 15, 2011. The Company is currently evaluating the impact of the adoption of this amendment, but does not expect it to have a material effect on the Company’s financial position or results of operations.

In May 2011, FASB issued amendments to FASB ASC Topic 820, Fair Value Measurement . The amendments were to achieve common fair value measurement and disclosure requirements in U.S. GAAP and International Financial Reporting Standards. The amendments change the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. The amendments are effective prospectively during interim and annual periods beginning after December 15, 2011. The Company is currently evaluating the impact of the adoption of this amendment, but does not expect it to have a material effect on the Company’s financial position or results of operations.

In April 2011, FASB issued amendments to FASB ASC Topic 310, Receivables. The amendments provide additional guidance or clarification regarding a creditor’s determination of whether a restructuring is a troubled debt restructuring. In evaluating whether a restructuring constitutes a troubled debt restructuring, a creditor must separately conclude that both of the following exist: 1) the restructuring constitutes a concession, and 2) the debtor is experiencing financial difficulties. The amendment provides further guidance as to when the creditor has granted a concession and the debtor is experiencing financial difficulties. The amendments are effective for the first interim or annual period beginning on or after June 15, 2011, and should be applied retrospectively to the beginning of the annual period of adoption. As a result of applying these amendments, an entity may identify receivables that are newly considered impaired. For purposes of measuring impairment of those receivables, an entity should apply the amendments prospectively for the first interim or annual period beginning on or after June 15, 2011. An entity should disclose the information relating to troubled debt restructurings which was deferred in January 2011 by Accounting Standards Update No. 2011-01, Topic 310, Receivables (Topic 310) , for interim and annual periods beginning on or after June 15, 2011. The Company has evaluated the impact of the adoption of this amendment and determined there was not a material effect on the Company’s financial position or results of operations.

In December 2010, FASB issued amendments to FASB ASC Topic 805, Business Combinations . The amendments specify that if a public entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. The amendments also expand the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings. The amendments are effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. The Company has evaluated the impact of the adoption of this amendment and determined there was not a material effect on the Company’s financial position or results of operations.

In December 2010, FASB issued amendments to FASB ASC Topic 350, Intangibles – Goodwill and Other . The amendments affect all entities that have recognized goodwill and have one or more reporting units whose carrying amount for purposes of performing Step 1 of the goodwill impairment test is zero or negative. The amendments modify Step 1 so that for those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more-likely-than-not that a goodwill impairment exists. In determining whether it is more-likely-than-not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. The Company has evaluated the impact of the adoption of this amendment and determined there was not a material effect on the Company’s financial position or results of operations.
