Notes to Unaudited Consolidated Financial Statements (In thousands, except share and per share data)

(1) Basis of Presentation

xbrl,body

In the opinion of management, the accompanying unaudited consolidated financial statements of First Interstate BancSystem, Inc. (the Parent Company or FIBS) and subsidiaries (the Company) contain all adjustments (all of which are of a normal recurring nature) necessary to present fairly the financial position of the Company at September 30, 2010 and December 31, 2009, the results of operations for each of the three and nine month periods ended September 30, 2010 and 2009 and cash flows for the nine months ended September 30, 2010 and 2009, in conformity with U.S. generally accepted accounting principles (GAAP). The balance sheet information at December 31, 2009 is derived from audited consolidated financial statements. Certain reclassifications, none of which were material, have been made to conform prior year financial statements to the September 30, 2010 presentation. These reclassifications did not change previously reported net income or stockholders equity.

These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in the Companys Annual Report on Form 10-K for the year ended December 31, 2009. Operating results for the three and nine months ended September 30, 2010 are not necessarily indicative of the results that may be expected for the year ending December 31, 2010.

On March 5, 2010, the Companys shareholders approved proposals to recapitalize the Companys existing common stock. The recapitalization included, among other things, a redesignation of existing common stock as Class B common stock; a four-for-one stock split of the Class B common stock; and, the creation of a new class of common stock designated as Class A common stock. All share and per share information included in the accompanying consolidated financial statements, including the notes thereto, has been adjusted to give effect to the recapitalization of the common stock, including the four-for-one stock split of Class B common stock, as if the recapitalization had occurred on January 1, 2009, the earliest date presented. For additional information regarding the recapitalization, see Note 5 Common Stock.

| The investment portfolio is evaluated quarterly for other-than-temporary declines in the
market value of each individual investment security. Consideration is given to the length of time
and the extent to which the fair value has been less than cost; the financial condition and near
term prospects of the issuer; and, the intent and ability of the Company to retain its investment
in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.
As of September 30, 2010, the Company had 19 individual investment securities that were in an
unrealized loss position. As of December 31, 2009, the Company had 75 individual investment
securities that were in an unrealized loss position. Unrealized losses as of September 30, 2010
and December 31, 2009 related to fluctuations in the current interest rates. As of
September 30, 2010, the Company had the intent and ability to hold these investment securities for
a period of time sufficient to allow for an anticipated recovery. Furthermore, the Company does
not have the intent to sell any of the available-for-sale securities in the above table and it is
more likely than not that the Company will not have to sell any such securities before a recovery
of cost. No impairment losses were recorded during the three and nine months ended September 30,
2010 and 2009. |

(9) Financial Instruments with Off-Balance Sheet Risk

xbrl,body

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the commitment contract. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. At September 30, 2010, commitments to extend credit to existing and new borrowers approximated $1,041,793, which includes $265,624 on unused credit card lines and $262,032 with commitment maturities beyond one year.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. At September 30, 2010, the Company had outstanding standby letters of credit of $79,531. The estimated fair value of the obligation undertaken by the Company in issuing the standby letters of credit is included in other liabilities in the Companys consolidated balance sheet.

Additions during the period	155		245
Deletions during the period	(118	)
Balance, end of period	$ 282	$	245

The following methods were used to estimate the fair value of each class of financial instrument above:

Investment Securities Available-for-Sale . The Company obtains fair value measurements for investment securities available-for-sale from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the investments terms and conditions, among other things.

Mortgage Servicing Rights. Mortgage servicing rights are initially recorded at fair value based on comparable market quotes and are amortized in proportion to and over the period of estimated net servicing income. Mortgage servicing rights are evaluated quarterly for impairment using an independent valuation service. The valuation service utilizes discounted cash flow modeling techniques, which consider observable data that includes market consensus prepayment speeds and the predominant risk characteristics of the underlying loans including loan type, note rate and loan term. Management believes the significant inputs utilized in the valuation model are observable in the market.

Derivative Liability Contract. In conjunction with the sale of all of its Class B shares of Visa, Inc. (Visa) common stock in 2009, the Company entered into a derivative liability contract with the purchaser whereby the Company will make or receive cash payments based on subsequent changes in the conversion rate of the Class B shares into Class A shares of Visa. The conversion rate is dependent upon the resolution of certain litigation involving Visa U.S.A. Inc. card association or its affiliates. The value of the derivative liability contract is estimated based on the Companys expectations regarding the ultimate resolution of that litigation, which involves a high degree of judgment and subjectivity. On May 28, 2010, Visa disclosed it had provided additional funding to its litigation escrow account thereby reducing the conversion rate of the Class B shares into Class A shares. In conjunction with the change in conversion rate, the Company made a cash payment to the purchaser of $118. On October 8, 2010, Visa disclosed it had provided additional funding to its litigation escrow account which further reduced the conversion rate. This funding, as well as a revision to the Companys estimate of Visas future funding, resulted in an increase in the derivative contract liability of $155 to $282 as of September 30, 2010.

Additionally, from time to time, certain assets are measured at fair value on a non-recurring basis. Adjustments to fair value generally result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairment.

Impaired Loans. Certain impaired loans are reported at the fair value of the underlying collateral if repayment is expected solely from collateral. The impaired loans are reported at fair value through specific valuation allowance allocations. In addition, when it is determined that the fair value of an impaired loan is less than the recorded investment in the loan, the carrying value of the loan is adjusted to fair value through a charge to the allowance for loan losses. Collateral values are estimated using inputs based upon observable market data and customized discounting criteria.

OREO. The fair values of OREO are determined by independent appraisals or are estimated using observable market data and customized discounting criteria. Upon initial recognition, write-downs based on the foreclosed assets fair value at foreclosure are reported through charges to the allowance for loan losses. Periodically, the fair value of foreclosed assets is remeasured with any subsequent write-downs charged to OREO expense in the period in which they are identified.

Long-lived Assets to be Disposed of by Sale. Long-lived assets to be disposed of by sale are carried at the lower of carrying value or fair value less estimated costs to sell. The fair values of long-lived assets to be disposed of by sale are based upon observable market data and customized discounting criteria.

Mortgage Loans Held for Sale . Mortgage loans held for sale are required to be measured at the lower of cost or fair value. The fair value of mortgage loans held for sale is based upon binding contracts or quotes or bids from third party investors. As of September 30, 2010 and December 31, 2009, all mortgage loans held for sale were recorded at cost.

The Company is required to disclose the fair value of financial instruments for which it is practical to estimate fair value. The methodologies for estimating the fair value of financial instruments that are measured at fair value on a recurring or non-recurring basis are discussed above. The methodologies for estimating the fair value of other financial instruments are discussed below. For financial instruments bearing a variable interest rate where no credit risk exists, it is presumed that recorded book values are reasonable estimates of fair value.

Financial Assets. Carrying values of cash, cash equivalents and accrued interest receivable approximate fair values due to the liquid and/or short-term nature of these instruments. Fair values for investment securities held-to-maturity are obtained from an independent pricing service, which considers observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the investments terms and conditions, among other things. Fair values of fixed rate loans and variable rate loans that reprice on an infrequent basis are estimated by discounting future cash flows using current interest rates at which similar loans with similar terms would be made to borrowers of similar credit quality. Carrying values of variable rate loans that reprice frequently, and with no change in credit risk, approximate the fair values of these instruments.

Financial Liabilities. The fair values of demand deposits, savings accounts, securities sold under repurchase agreements and accrued interest payable are the amount payable on demand at the reporting date. The fair values of fixed-maturity certificates of deposit are estimated using external market rates currently offered for deposits with similar remaining maturities. The carrying values of the interest bearing demand notes to the United States Treasury are deemed an

approximation of fair values due to the frequent repayment and repricing at market rates. The fair value of the derivative contract was estimated by discounting cash flows using assumptions regarding the expected outcome of related litigation. The floating rate term notes, floating rate subordinated debentures, floating rate subordinated term loan and unsecured demand notes bear interest at floating market rates and, as such, carrying amounts are deemed to approximate fair values. The fair values of notes payable to the FHLB, fixed rate subordinated term debt and capital lease obligation are estimated by discounting future cash flows using current rates for advances with similar characteristics.

Commitments to Extend Credit and Standby Letters of Credit. The fair value of commitments to extend credit and standby letters of credit, based on fees currently charged to enter into similar agreements, is not significant.

A summary of the estimated fair values of financial instruments follows:

(13) Authoritative Accounting Guidance

xbrl,body

FASB ASC Topic 310, Receivables. New authoritative accounting guidance under Accounting Standard Codification (ASC) Topic 310, Receivables, clarifies that modifications of loans that are accounted for within a pool under Subtopic 310-30 do not result in the removal of those loans from the pool even if the modification of those loans would otherwise be considered a troubled debt restructuring. An entity will continue to be required to consider whether the pool of assets in which the loan is included is impaired if expected cash flows for the pool change. This guidance became effective prospectively for modifications of loans accounted for within pools under Subtopic 310-30 occurring after June 30, 2010. The adoption of this new authoritative guidance under ASC Topic 310 did not impact the Companys consolidated financial statements, results of operations or liquidity.

Additional new authoritative accounting guidance (Accounting Standards Update (ASU) No. 2010-20) under ASC Topic 310, Receivables, requires significant new disclosures about the allowance for credit losses and the credit quality of financing receivables. The requirements are intended to enhance transparency regarding credit losses and the credit quality of loan and lease receivables. Under this statement, allowance for credit losses and fair value are to be disclosed by portfolio segment, while credit quality information, impaired financing receivables and non-accrual status are to be presented by class of financing receivable. Disclosure of the nature and extent, the financial impact and segment information of troubled debt restructurings will also be required. The disclosures are to be presented at the level of disaggregation that management uses when assessing and monitoring the portfolios risk and performance. This ASU is effective for interim and annual reporting periods after December 15, 2010. The Company will include these disclosures in the notes to the financial statements beginning December 31, 2010.

FASB ASC Topic 855, Subsequent Events. New authoritative accounting guidance under ASC Topic 855, Subsequent Events, amends prior guidance. Under this amended guidance, SEC filers are no longer required to disclose the date through which subsequent events have been evaluated in originally issued and revised financial statements. This guidance became effective immediately and the Company adopted these new requirements for the period ended March 31, 2010.

FASB ASC Topic 810, Consolidation. Authoritative accounting guidance under ASC Topic 810, Consolidation, amends prior guidance to change how a company determines when an entity that is insufficiently capitalized or is not controlled through voting (or similar rights) should be consolidated. The determination of whether a company is required to consolidate an entity is based on, among other things, an entitys purpose and design and a companys ability to direct the activities of the entity that most significantly impact the entitys economic performance. The new authoritative accounting guidance requires additional disclosures about the reporting entitys involvement with variable-interest entities and any significant changes in risk exposure due to that involvement as well as its affect on the entitys financial statements. The new authoritative accounting guidance under ASC Topic 810 became effective for the Companys financial statements for periods ending after January 1, 2010. The adoption of this authoritative guidance did not have a significant impact on the Companys consolidated financial statements, results of operations or liquidity.

FASB ASC Topic 820, Fair Value Measurements and Disclosures. New authoritative accounting guidance (ASU No. 2010-06) under ASC Topic 820 requires a reporting entity to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers; and, present separately information about purchases, sales, issuances and settlements in the reconciliation for fair value measurements using Level 3 inputs. In addition, ASU No. 2010-06 clarifies that reporting entities must use judgment in determining the appropriate classes of assets and liabilities for purposes of reporting fair value measurements and disclose valuation techniques and inputs used to measure both recurring and nonrecurring fair value measurements. ASU No. 2010-06 became effective for the Company on January 1, 2010, except for disclosures about purchases, sales, issuances and settlements in the reconciliation for fair value measurements using Level 3 inputs. Those disclosures are effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. The adoption of this new authoritative guidance under ASC Topic 820 did not and is expected not to have a material impact on the Companys consolidated financial statements, results of operations or liquidity.

FASB ASC Topic 860, Transfers and Servicing. New authoritative accounting guidance (ASU No. 2009-16) under ASC Topic 860, Transfers and Servicing, amends prior accounting guidance to enhance reporting about transfers of financial assets, including securitizations, and where companies have continuing exposure to the risks related to transferred financial assets. The new authoritative accounting guidance eliminates the concept of a qualifying special-purpose entity and changes the requirements for derecognizing financial assets. The new authoritative accounting guidance also requires additional disclosures about all continuing involvements with transferred financial assets including information about gains and losses resulting from transfers during the period. The new authoritative accounting guidance under ASC Topic 860, which became effective for the Company on January 1, 2010, did not have a significant impact on the Companys consolidated financial statements, results of operations or liquidity.

Executive Overview

We are a financial and bank holding company headquartered in Billings, Montana. As of September 30, 2010, we had consolidated assets of $7,329 million, deposits of $5,902 million, loans of $4,452 million and total stockholders equity of $745 million. We currently operate 72 banking offices in 42 communities located in Montana, Wyoming and western South Dakota. Through our bank subsidiary, First Interstate Bank, or the Bank, we deliver a comprehensive range of banking products and services to individuals, businesses, municipalities and other entities throughout our market areas. Our customers participate in a wide variety of industries, including energy, healthcare and professional services, education and governmental services, construction, mining, agriculture, retail and wholesale trade and tourism.

Our principal business activity is lending to and accepting deposits from individuals, businesses, municipalities and other entities. We derive our income principally from interest charged on loans and, to a lesser extent, from interest and dividends earned on investments. We also derive income from non-interest sources such as fees received in connection with various lending and deposit services; trust, employee benefit, investment and insurance services; mortgage loan originations, sales and servicing; and, merchant and electronic banking services. Our principal expenses include interest expense on deposits and borrowings, operating expenses, provisions for loan losses and income tax expense.

Our loan portfolio consists of a mix of real estate, consumer, commercial, agricultural and other loans, including fixed and variable rate loans. Our real estate loans comprise commercial real estate, construction (including residential, commercial and land development loans), residential, agricultural and other real estate loans. Fluctuations in the loan portfolio are directly related to the economies of the communities we serve. While each loan originated generally must meet minimum underwriting standards established in our credit policies, lending officers are granted discretion within pre-approved limits in approving and pricing loans to assure that the banking offices are responsive to competitive issues and community needs in each market area. Loans exceeding the pre-approved lending limits of our lending officers are subject to additional review and approval by management and the board of directors of the Bank. We fund our loan portfolio primarily with the core deposits from our customers, generally without utilizing brokered deposits and with minimal reliance on wholesale funding sources.

On March 5, 2010, our shareholders approved proposals to recapitalize our existing common stock. The recapitalization included a redesignation of existing common stock as Class B common stock with five votes per share, convertible into Class A common stock on a share for share basis; a four-for-one stock split of the Class B common stock; an increase in the authorized number of Class B common shares from 20,000,000 to 100,000,000; and the creation of a new class of common stock designated as Class A common stock, with one vote per share, with 100,000,000 shares authorized. The Class A common stock and Class B common stock are collectively referred to as common stock in this report. All share and per share information included in this report has been adjusted to give effect to the recapitalization of the common stock, including the four-for-one stock split of Class B common stock, as if the recapitalization had occurred on January 1, 2009, the earliest date presented.

On March 29, 2010, we concluded our initial public offering, or IPO, of 10,000,000 shares of Class A common stock, and an additional 1,500,000 shares of Class A common stock pursuant to the full exercise of the underwriters option to purchase Class A common shares in the offering. We received net proceeds of $153 million from the sale of the shares, after deducting the underwriting discount, commissions and other offering expenses.

Primary Factors Used in Evaluating Our Business

As a banking institution, we manage and evaluate various aspects of both our financial condition and our results of operations. We monitor our financial condition and performance on a monthly basis, at our holding company, at the Bank and at each banking office. We evaluate the levels and trends of the line items included in our balance sheet and statements of income, as well as various financial ratios that are commonly used in our industry. We analyze these

Folio 20 /Folio

Table of Contents

ratios and financial trends against both our own historical levels and the financial condition and performance of comparable banking institutions in our region and nationally.

Results of Operations

Principal factors used in managing and evaluating our results of operations include net interest income, non-interest income, non-interest expense and net income.

Net interest income. Net interest income, the largest source of our operating income, is derived from interest, dividends and fees received on interest earning assets, less interest expense incurred on interest bearing liabilities. Interest earning assets primarily include loans and investment securities. Interest bearing liabilities include deposits and various forms of indebtedness. Net interest income is affected by the level of interest rates, changes in interest rates and changes in the composition of interest earning assets and interest bearing liabilities. The most significant impact on our net interest income between periods is derived from the interaction of changes in the rates earned or paid on interest earning assets and interest bearing liabilities, which we refer to as interest rate spread. The volume of loans, investment securities and other interest earning assets, compared to the volume of interest bearing deposits and indebtedness, combined with the interest rate spread, produces changes in our net interest income between periods. Non-interest bearing sources of funds, such as demand deposits and stockholders equity, also support earning assets. The impact of free funding sources is captured in the net interest margin, which is calculated as net interest income divided by average earning assets. Given the interest free nature of free funding sources, the net interest margin is generally higher than the interest rate spread. We seek to increase our net interest income over time, and we evaluate our net interest income on factors that include the volumes of and yields on our loans and other earning assets, the costs of our deposits and other funding sources, the levels of our net interest spread and net interest margin and the provisions for loan losses required to maintain our allowance for loan losses at an adequate level.

Non-interest income. Our principal sources of non-interest income include (1) income from the origination and sale of loans, (2) other service charges, commissions and fees, (3) service charges on deposit accounts, (4) wealth management revenues and (5) other income. Income from the origination and sale of loans includes origination and processing fees on residential real estate loans held for sale and gains on residential real estate loans sold to third parties. Fluctuations in market interest rates have a significant impact on revenues generated from the origination and sale of loans. Higher interest rates can reduce the demand for home loans and loans to refinance existing mortgages. Conversely, lower interest rates generally stimulate refinancing and home loan origination. Other service charges, commissions and fees primarily include debit and credit card interchange income, mortgage servicing fees, insurance and other commissions and ATM service charge revenues. Wealth management revenues principally comprises fees earned for management of trust assets and investment services revenues. Other income primarily includes company-owned life insurance revenues, check printing income, agency stock dividends and gains on sales of miscellaneous assets. We seek to increase our non-interest income over time, and we evaluate our non-interest income relative to the trends of the individual types of non-interest income in view of prevailing market conditions.

Non-interest expense. Non-interest expenses include (1) salaries, wages and employee benefits expense, (2) occupancy expense, (3) furniture and equipment expense, (4) Federal Deposit Insurance Corporation, or FDIC, insurance premiums, (5) outsourced technology services expense, (6) impairment of mortgage servicing rights, (7) other real estate owned, or OREO, expense, (8) core deposit intangibles and (9) other expenses, which primarily includes professional fees; advertising and public relations costs; office supply, postage, freight, telephone and travel expenses; donations expense; debit and credit card expenses; board of director fees; and other losses. OREO expense is recorded net of OREO income. Variations in net OREO expense between periods is primarily due to write-downs of the estimated fair value of OREO properties, fluctuations in gains and losses recorded on sales of OREO properties, fluctuations in the number of OREO properties held and the carrying costs and/or operating expenses associated with those properties. We seek to manage our non-interest expenses in consideration of the growth of our business and our community banking model that emphasizes customer service and responsiveness. We evaluate our non-interest expense on factors that include our non-interest expense relative to our average assets, our efficiency ratio and the trends of the individual categories of non-interest expense.

Net Income. We seek to increase our net income and provide favorable stockholder returns over time, and we evaluate our net income relative to the performance of other banks and bank holding companies on factors that include return on average assets, return on average equity and consistency and rates of growth in our earnings.

Financial Condition

Principal areas of focus in managing and evaluating our financial condition include liquidity, the diversification and quality of our loans, the adequacy of our allowance for loan losses, the diversification and terms of our deposits and other funding sources, the re-pricing characteristics and maturities of our assets and liabilities, including potential interest rate exposure and the adequacy of our capital levels. We seek to maintain sufficient levels of cash and investment securities to meet potential payment and funding obligations, and we evaluate our liquidity on factors that include the levels of cash and highly liquid assets relative to our liabilities, the quality and maturities of our investment securities, our ratio of loans to deposits and our reliance on brokered certificates of deposit or other wholesale funding sources.

We seek to maintain a diverse and high quality loan portfolio, and we evaluate our asset quality on factors that include the allocation of our loans among loan types, credit exposure to any single borrower or industry type, non-performing assets as a percentage of total loans and OREO, and loan charge-offs as a percentage of average loans. We seek to maintain our allowance for loan losses at a level adequate to absorb potential losses inherent in our loan portfolio at each balance sheet date, and we evaluate the level of our allowance for loan losses relative to our overall loan portfolio and the estimated loss exposure on non-performing loans.

We seek to fund our assets primarily using core customer deposits spread among various deposit categories, and we evaluate our deposit and funding mix on factors that include the allocation of our deposits among deposit types, the level of our non-interest bearing deposits, the ratio of our core deposits (i.e. excluding time deposits above $100,000) to our total deposits and our reliance on brokered deposits or other wholesale funding sources, such as borrowings from other banks or agencies. We seek to manage the mix, maturities and re-pricing characteristics of our assets and liabilities to maintain relative stability of our net interest rate margin in a changing interest rate environment, and we evaluate our asset-liability management using complex models to evaluate the changes to our net interest income under different interest rate scenarios.

Finally, we seek to maintain adequate capital levels to absorb unforeseen operating losses and to help support the growth of our balance sheet. We evaluate our capital adequacy using the regulatory and financial capital ratios including leverage capital ratio, tier 1 risk-based capital ratio, total risk-based capital ratio, tangible common equity to tangible assets and tier 1 common capital to total risk-weighted assets.

Trends and Developments

Our success is highly dependent on economic conditions and market interest rates. Because we operate in Montana, Wyoming and western South Dakota, the local economic conditions in each of these areas are particularly important. Most of our local economies have not been impacted as severely by the national economic and real estate downturn, sub-prime mortgage crisis and ongoing financial market turbulence as many areas of the United States. The continuing impact of the national recession and related real estate and financial market conditions is uncertain and could have a material negative effect on our cash flows, results of operations, financial condition and prospects.

Capital Resources

On March 29, 2010, we concluded our IPO of 10,000,000 shares of Class A common stock, and an additional 1,500,000 shares of Class A common stock pursuant to the full exercise of the underwriters option to purchase Class A common shares in the offering. We received net proceeds of $153 million from the offering, after deducting the underwriting discount, commissions and other offering expenses.

Asset Quality

Challenging economic conditions continue to have a negative impact on businesses and consumers in some of our market areas. General declines in the real estate and housing markets resulted in continued deterioration in the credit quality of our loan portfolio, which is reflected by increases in non-performing and internally risk classified loans. Our non-performing assets increased to $237 million, or 5.29% of total loans and OREO, as of September 30, 2010, from $163 million, or 3.57% of total loans and OREO, as of December 31, 2009. Loan charge-offs, net of recoveries, totaled $12.1 million and $32.2 million during the three and nine months ended September 30, 2010, respectively, compared to $7.1 million and $17.4 million during the same respective periods in 2009, with all major loan categories reflecting increases. Based on our assessment of the adequacy of our allowance for loan losses, we recorded provisions for loan losses of $18.0 million and $49.4 million during the three and nine months ended September, 30, 2010, respectively, compared to $10.5 million and $31.8 million during the same respective periods in 2009. Increased provisions for loan losses reflect our estimation of the effect of current economic conditions on our loan portfolio. During the first nine months of 2010, we have

Folio 22 /Folio

PAGEBREAK

Table of Contents

continued to experience elevated provisions for loan losses and higher levels of non-performing assets, which will continue to affect our earnings. Given the current economic conditions and trends, management believes we will continue to experience higher levels of non-performing loans in future quarters, which will likely have an adverse impact on our business, financial condition, results of operations and prospects.

Dodd-Frank Wall Street Reform and Consumer Protection Act

On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Act, was signed into legislation. The Act dramatically rewrites the rules governing financial service providers and products, and implementation of the Act will require new mandatory and discretionary rulemakings by numerous Federal regulatory agencies over the next several years. In general, the Act:

| | Creates a systemic-risk council of top regulators, the Financial Stability Oversight
Council, whose purpose is to identify risks and respond to emerging threats to the
financial stability of the U.S. arising from large, interconnected bank holding companies
or nonbank financial companies. |
| --- | --- |
| | Centralizes the responsibility for consumer financial protection by creating a new
agency, the Consumer Financial Protection Bureau, responsible for implementing, examining
and enforcing compliance with federal consumer financial laws. |
| | Gives the FDIC authority to unwind large failing financial firms. Regulators would
recoup any losses incurred from wind-downs by assessing fees on financial firms with more
than $50 billion in assets. |
| | Directs the FDIC to base deposit insurance assessments on assets minus tangible capital
instead of on domestic deposits and requires the FDIC to increase premium rates to raise
the Deposit Insurance Funds (DIF) minimum reserve ratio from 1.15% to 1.35% by September
30, 2020. The Act also eliminates automatic dividends when the minimum reserve ratio
exceeds 1.35%. |
| | Extends the FDICs TAG program through December 31, 2012. The extension applies only to
non-interest bearing transaction accounts. |
| | Authorizes banks to pay interest on business checking accounts. |
| | Directs the Federal Reserve to set interchange fees for debit card transactions charged
by banks with more than $10 billion in assets. |
| | Excludes proceeds of trust preferred securities from Tier 1 capital except for trust
preferred securities issued before May 19, 2010 by bank holding companies, like us, with
less than $15 billion in assets at December 31, 2010. |
| | Requires loan originators to retain 5% of any loan sold or securitized, unless
it is a qualified residential mortgage, which includes standard 30 and 15 year fixed-rate
loans. |
| | Adopts various mortgage lending and predatory lending provisions. |
| | Requires federal regulators to jointly prescribe regulations mandating
financial institutions with more than $1 billion in assets to disclose their incentive
compensation plans to permit the regulators to determine whether the plans provide
executive officers, employees, directors or principal shareholders with excessive
compensation, fees or benefits; or could lead to material financial loss to the
institution. |
| | Imposes a number of requirements related to executive compensation that apply to all
public companies, such as prohibition of broker discretionary voting in connection with a
shareholder vote on executive compensation; mandatory shareholder say on pay every one to
three years and say on golden parachutes; and claw-back of incentive compensation from
current or former executive officers following any accounting restatement. |

Many provisions of the Act are subject to rulemaking and will take effect over several years, making it difficult to anticipate the overall financial impact to us, our customers and the financial industry in general. Provisions of the Act that affect deposit insurance assessments, payment of interest on demand deposits and interchange fees could increase the costs associated with deposits as well as place limitations on certain revenues those deposits may generate. Provisions of the Act that revoke Tier 1 capital treatments of trust preferred securities and otherwise require revisions to capital requirements may cause us to seek other sources of capital in the future.

Temporary Liquidity Guarantee Program

In April 2010, the FDIC approved an interim rule that extends the Transaction Account Guarantee (TAG) component of the Temporary Liquidity Guarantee Program. The TAG program provides full FDIC insurance coverage for non-interest bearing transaction deposit accounts, certain Negotiable Order of Withdrawal (NOW) accounts and Interest on

Folio 23 /Folio

Table of Contents

Lawyers Trust accounts. Participants in the TAG program had a one-time, irrevocable opportunity to opt out of the TAG extension by notifying the FDIC by April 30, 2010. We opted out of the TAG extension effective July 1, 2010. Management does not expect deposits will be adversely affected by discontinuation of the TAG program.

Basel III Capital Standards

On September 12, 2010, the international oversight body of the Basel Committee on Banking Supervision, or Basel Committee, announced they had agreed to new standards that will substantially strengthen existing capital requirements. United States federal banking agencies support the agreement, which calls for national jurisdictions to phase-in the new standards beginning January 1, 2013. If the standards, known as Basel III, are adopted by U.S. federal banking agencies as agreed upon by the oversight body of the Basel Committee, the minimum common equity requirements would increase from 2.0% to 4.5% of risk-weighted assets. In addition, banks would be required to hold a capital conservation buffer of 2.5% to withstand future periods of stress bringing the total common equity requirements to 7.0% of risk-weighted assets. In addition, Basel III would increase Tier 1 capital requirements from 4.0% to 6.0%. The new minimums would be phased in between January 1, 2013 and January 1, 2015, while the capital conservation buffer would be phased in between January 1, 2016 and December 31, 2018. Under Basel III, an additional capital buffer of up to 2.5% would also be imposed under certain circumstances. Basel III would also narrow the definition of capital, excluding instruments that no longer qualify as Tier 1 common equity as of January 1, 2013, and phasing out other instruments over several years. In addition, a new rule requiring banks to hold enough liquid capital to meet needs over a 30-day period would be introduced on January 1, 2015, and a longer-term liquidity rule, called the net stable funding ratio, would be applied starting January 1, 2018.

Small Business Jobs Act of 2010

On September 27, 2010, the Small Business Jobs Act of 2010, or the Jobs Act, was signed into legislation. The Jobs Act, among other things, creates a $30 billion fund, the Small Business Lending Fund, to provide capital for banks with assets under $10 billion to increase their small business lending. Management believes our current capital and liquidity is sufficient to fund loan demand in our market areas. As such, we do not anticipate we will participate in the Small Business Lending Fund program.

Critical Accounting Estimates and Significant Accounting Policies

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States and follow general practices within the industries in which we operate. Application of these principles requires management to make estimates, assumptions and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. The most significant accounting policies we follow are presented in Note 1 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2009.

Our critical accounting estimates are summarized below. Management considers an accounting estimate to be critical if: (1) the accounting estimate requires management to make particularly difficult, subjective and/or complex judgments about matters that are inherently uncertain and (2) changes in the estimate that are reasonably likely to occur from period to period, or the use of different estimates that management could have reasonably used in the current period, would have a material impact on our consolidated financial statements, results of operations or liquidity.

Allowance for Loan Losses

The provision for loan losses creates an allowance for loan losses known and inherent in the loan portfolio at each balance sheet date. The allowance for loan losses represents managements estimate of probable credit losses inherent in the loan portfolio.

We perform a quarterly assessment of the risks inherent in our loan portfolio, as well as a detailed review of each significant asset with identified weaknesses. Based on this analysis, we record a provision for loan losses in order to maintain the allowance for loan losses at appropriate levels. In determining the allowance for loan losses, we estimate losses on specific loans, or groups of loans, where the probable loss can be identified and reasonably determined. Determining the amount of the allowance for loan losses is considered a critical accounting estimate because it requires significant judgment and the use of subjective measurements, including managements assessment of the internal risk classifications of loans, historical loan loss rates, changes in the nature of the loan portfolio, overall portfolio quality, industry concentrations, delinquency trends and the impact of current local, regional and national economic factors on the quality of the loan portfolio. Changes in these estimates and assumptions are possible and may have a material impact on our allowance, and therefore our consolidated financial statements, liquidity or results of operations. The allowance for loan losses is maintained at an amount we believe is sufficient to provide for estimated losses inherent in our loan portfolio at each balance sheet date, and fluctuations in the provision for loan losses result from managements assessment of the adequacy of the allowance for loan losses. Management monitors qualitative and quantitative trends in the loan portfolio, including changes in the levels of past due, internally classified and non-performing loans. Note 1 of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2009 describes the methodology used to determine the allowance for loan losses. A discussion of the factors driving changes in the amount of the allowance for loan losses is included herein under the heading Asset Quality.

Goodwill

The excess purchase price over the fair value of net assets from acquisitions, or goodwill, is evaluated for impairment at least annually and on an interim basis if an event or circumstance indicates that it is likely an impairment has occurred. In testing for impairment, the fair value of net assets is estimated based on an analysis of our market value. Determining the fair value of goodwill is considered a critical accounting estimate because of its sensitivity to market-based trading of our Class A common stock. In addition, any allocation of the fair value of goodwill to assets and liabilities requires significant management judgment and the use of subjective measurements. Variability in the market and changes in assumptions or subjective measurements used to allocate fair value are reasonably possible and may have a material impact on our consolidated financial statements, liquidity or results of operations. Note 1 of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2009 describes our accounting policy with regard to goodwill.

Valuation of Mortgage Servicing Rights

We recognize as assets the rights to service mortgage loans for others, whether acquired or internally originated. Mortgage servicing rights are carried on the consolidated balance sheet at the lower of amortized cost or fair value. We utilize the expertise of a third-party consultant to estimate the fair value of our mortgage servicing rights quarterly. In evaluating the mortgage servicing rights, the consultant uses discounted cash flow modeling techniques, which require estimates regarding the amount and timing of expected future cash flows, including assumptions about loan repayment rates based on current industry expectations, costs to service, predominant risk characteristics of the underlying loans as well as interest rate assumptions that contemplate the risk involved. During a period of declining interest rates, the fair value of mortgage servicing rights is expected to decline due to anticipated prepayments within the portfolio. Alternatively, during a period of rising interest rates, the fair value of mortgage servicing rights is expected to increase because prepayments of the underlying loans would be anticipated to decline. Impairment adjustments are recorded through a valuation allowance. The valuation allowance is adjusted for changes in impairment through a charge to current period earnings. Management believes the valuation techniques and assumptions used by the consultant are reasonable.

Determining the fair value of mortgage servicing rights is considered a critical accounting estimate because of the assets sensitivity to changes in estimates and assumptions used, particularly loan prepayment speeds and discount rates. Changes in these estimates and assumptions are reasonably possible and may have a material impact on our consolidated financial statements, liquidity or results of operations. Notes 1 and 8 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2009 describe the methodology we use to determine fair value of mortgage servicing rights.

OREO

Real estate acquired in satisfaction of loans is initially carried at current fair value less estimated selling costs. At the time of transfer, the value of the underlying loan is written down to the fair value of the real estate acquired by charge to the allowance for loan losses, if necessary. Subsequent declines in fair value less estimated selling costs are included in OREO expense. Subsequent increases in fair value less estimated selling costs are recorded as a reduction in OREO expense to the extent of recognized losses. Carrying costs, operating expenses, net of related income, and gains or losses on sales are included in OREO expense. Note 1 of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2009 describes our accounting policy with regard to OREO.

Results of Operations

The following discussion and analysis is intended to provide greater details of the results of our operations and financial condition.

Net Interest Income. Deposit growth combined with corresponding increases in interest earning assets resulted in increases in net interest income, on a fully taxable equivalent, or FTE basis. Our FTE net interest income increased $2.3 million, or 3.7%, to $64.8 million for the three months ended September 30, 2010, as compared to $62.5 million for the same period in 2009, and increased $8.7 million, or 4.7%, to $192.0 million for the nine months ended September 30, 2010, as compared to $183.3 million for the same period in 2009.

Despite increases in our FTE net interest income, we experienced lower interest rate spreads and compression of our net FTE interest margin ratio. Our FTE net interest margin ratio decreased 11 basis points to 3.89% for the three months ended September 30, 2010, from 4.00% during the same period in the prior year, and decreased 10 basis points to 3.95% for the nine months ended September 30, 2010, from 4.05% during the same period in the prior year. Higher levels of loans on nonaccrual status and the resulting charge-off of interest on nonaccrual loans accounted for 5 basis points and 2 basis points of the reduction in FTE net interest margin during the three and nine months ended September 30, 2010, respectively, as compared to the same periods in 2009. In addition, deposit growth coupled with low demand for loans resulted in a shift in the mix of interest earning assets from higher-yielding loans to lower-yielding investment securities, which further compressed our FTE net interest margin ratio. Proceeds of $153 million from the Companys March 2010 IPO were invested in interest bearing deposits in banks which yielded 25 basis points during the second and third quarters of 2010.

Provision for Loan Losses. The provision for loan losses was $18.0 million during third quarter 2010, as compared to $19.5 million during second quarter 2010 and $10.5 million during third quarter 2009. The provision for loan losses increased $17.6 million, or 55.3%, to $49.4 million for the nine months ended September 30, 2010, compared to $31.8 million for the same period in 2009. Fluctuations in provisions for loan losses reflect managements estimate of the effects of current economic conditions on our loan portfolio. Ongoing stress from weakening economic conditions continues to negatively impact the performance of many of our real estate loans. For information regarding our non-performing loans, see Non-Performing Assets included herein.

Non-interest Income. Our principal sources of non-interest income include other service charges, commissions and fees; service charges on deposit accounts; income from the origination and sale of loans; and, revenues from wealth management. Non-interest income decreased $145 thousand, or 0.6%, to $24.9 million for the three months ended September 30, 2010, as compared to $25.0 million for the same period in 2009. Non-interest income decreased $13.1 million, or 16.7%, to $65.4 million for the nine months ended September 30, 2010, as compared to $78.5 million for the same period in 2009. Significant components of these decreases are discussed below.

Service charges on deposit accounts decreased $939 thousand, or 17.3%, to $4.5 million during the three months ended September 30, 2010, as compared to $5.4 million during the same period in 2009, and decreased $1.4 million, or 9.4%, to $13.9 million during the nine months ended September 30, 2010, as compared to $15.3 million during the same period in 2009, primarily due to decreases in overdraft fees. Management attributes the decline in overdraft fees to changes in consumer behavior. Additionally, the Federal Reserve Board issued a final rule that became effective on July 1, 2010 prohibiting financial institutions from charging consumers fees for paying overdrafts on automated teller machine and debit card transactions, unless the consumer consents, or opts in, to the overdraft service for those types of transactions. Management does not expect this rule will have a significant impact because we generally did not assess overdraft fees on automated teller machine and one-time debit card transactions.

Income from the origination and sale of loans includes origination and processing fees on residential real estate loans held for sale and gains on residential real estate loans sold to third parties. Income from the origination and sale of loans increased $2.3 million, or 44.5%, to $7.4 million for the three months ended September 30, 2010, as compared to $5.1 million for the same period in 2009. Refinancing activity accounted for approximately 69% of the Companys residential real estate loan originations during third quarter 2010, as compared to 45% during third quarter 2009. Increases in refinancing activity were partially offset by fewer originations of loans to purchase homes, which decreased 15% during third quarter 2010, as compared to third quarter 2009, in part due to the expiration of the federal first-time home buyers tax credit.

Income from the origination and sale of loans decreased $10.8 million, or 42.2%, to $14.8 million for the nine months ended September 30, 2010, as compared to $25.7 million for the same period in 2009, due to a substantial decline in refinancing activity from early 2009.

Wealth management revenues are comprised principally of fees earned for management of trust assets and investment services revenues. Fees earned for management of trust assets are generally based on the market value of assets managed. Wealth management revenues increased $350 thousand, or 12.8%, to $3.1 million for the three months ended September 30, 2010, as compared to $2.7 million for the same period in 2009, and increased $1.4 million, or 17.4%, to $9.3 million for the nine months ended September 30, 2010, as compared to $7.9 million for the same period in 2009. These increases were principally due to higher trust management fees resulting from the introduction of revised fee schedules in April 2009, the addition of new trust customers and increases in the market values of new and existing assets under trust management.

Other income decreased $1.6 million, or 43.8%, to $2.0 million for the three months ended September 30, 2010, compared to $3.6 million for the same period in 2009, and decreased $2.6 million, or 33.4%, to $5.2 million for the nine months ended September 30, 2010, compared to $7.8 million for the same period in 2009. These decreases are primarily due to the recognition of a $2.1 million one-time gain on the sale of Visa Class B common shares during third quarter 2009. Decreases in other income were partially offset by a $249 thousand one-time gain on the sale of our student loan portfolio recognized during third quarter 2010.

Non-interest Expense. Non-interest expense increased $634 thousand, or 1.1%, to $58.0 million for the three months ended September 30, 2010, as compared to $57.4 million for the same period in 2009. Non-interest expense increased $3.6 million, or 2.2%, to $166.2 million for the nine months ended September 30, 2010, as compared to $162.6 million for the same period in 2009. Significant components of the increase are discussed below.

Furniture and equipment expense increased $418 thousand, or 14.0%, to $3.4 million for the three months ended September 30, 2010, as compared to $3.0 million for the same period in 2009, and increased $1.1 million, or 12.1%, to $10.1 million for the nine months ended September 30, 2010, as compared to $9.0 million for the same period in 2009. These increases are primarily due to higher depreciation and maintenance expenses resulting from the addition of a new operations building and branch banking office placed in service during fourth quarter 2009.

FDIC insurance premiums decreased $40 thousand, or 1.7%, to $2.3 million for the three months ended September 30, 2010, as compared to $2.4 million for the same period in 2009 and decreased $2.3 million, or 23.4%, to $7.5 million for the nine months ended September 30, 2010, compared to $9.7 million for the same period in 2009. These decreases are primarily due to a special FDIC insurance assessment levied during second quarter 2009, which was applicable to all insured depository institutions, and resulted in additional FDIC insurance expense of $3.1 million. In addition, effective July 1, 2010, we opted out of participation in the Transaction Account Guarantee component of the Temporary Liquidity Guaranty Program, which provided full FDIC insurance coverage for certain transaction deposit accounts, which reduced our FDIC insurance premiums during third quarter 2010.

Outsourced technology services expense increased $68 thousand, or 2.9%, to $2.4 million for the three months ended September 30, 2010, compared to $2.3 million for the same period in 2009, and decreased $1.2 million, or 14.3%, to $7.1 million for the nine months ended September 30, 2010, compared to $8.3 million for the same period in 2009. On December 31, 2008, we sold our technology services subsidiary and entered into a service contract with the purchaser to receive technology services. First and second quarter 2009 outsourced technology services expense accruals were estimated resulting in an over-accrual of expense during these periods, which was adjusted during third quarter 2009.

OREO expense, net of income, decreased $2.6 million, or 49.5%, to $2.6 million for the three months ended September 30, 2010, compared to $5.2 million for the same period in 2009, and increased $50 thousand, or 0.8%, to $6.1 million for the nine months ended September 30, 2010, as compared to the same period in 2009. Variations in net OREO expense between periods were primarily due to fluctuations in write-downs of the estimated fair value of OREO properties. We wrote down the fair value of OREO properties by $2.4 million and $5.6 million during the three and nine months ended September 30, 2010, respectively, compared to $4.8 million and $5.5 million during the same respective periods in 2009.

Mortgage servicing rights amortization decreased $56 thousand, or 4.4%, to $1.2 million for the three months ended September 30, 2010, as compared to $1.3 million for the same period in 2009, and decreased $2.9 million, or 45.3%, to $3.5 million for the nine months ended September 30, 2010, as compared to $6.3 million for the same period in 2009. Mortgage servicing rights are amortized in proportion to and over the period of estimated net servicing income. The period of estimated net servicing income is significantly influenced by market interest rates and anticipated refinancing activity.

Mortgage servicing rights are evaluated quarterly for impairment based on the fair value of the mortgage servicing rights. The fair value of mortgage servicing rights is estimated by discounting the expected future cash flows, taking into consideration the estimated level of prepayments based on current industry expectations and the predominant risk characteristics of the underlying loans. Impairment adjustments are recorded through a valuation allowance. The valuation allowance is adjusted for changes in impairment through a charge to current period earnings. Fluctuations in the fair value of mortgage servicing rights are primarily due to changes in assumptions regarding prepayments of the underlying mortgage loans, which typically correspond with changes in market interest rates. During third quarter 2010, we recorded impairment of $2.0 million, as compared to impairment of $296 thousand during third quarter 2009. During the nine months ended September 30, 2010, we recorded impairment of $2.2 million, as compared to a reversal of previously recorded impairment of $7.0 million during the same period in 2009.

Income Tax Expense. Our effective federal income tax rate was 26.7% for the nine months ended September 30, 2010 and 29.3% for the nine months ended September 30, 2009. State income tax applies primarily to pretax earnings generated within Montana and South Dakota. Our effective state tax rate was 4.3% for the nine months ended September 30, 2010, and 4.2% for the nine months ended September 30, 2009. Changes in effective federal and state income tax rates are primarily due to fluctuations in tax exempt interest income as a percentage of total income.

Financial Condition

Total assets increased $192 million, or 2.7%, to $7,329 million as of September 30, 2010, from $7,138 million as of December 31, 2009.

Loans. Our loan portfolio consists of a mix of real estate, consumer, commercial, agricultural and other loans, including fixed and variable rate loans. Fluctuations in the loan portfolio are directly related to the economies of the communities we serve. Total loans decreased $76 million, or 1.7%, to $4,452 million as of September 30, 2010 from $4,528 million as of December 31, 2009, with the most significant decrease occurring in construction loans and other consumer loans.

Construction loans of $564 million as of September 30, 2010, decreased $73 million, or 11.4%, from $637 million as of December 31, 2009. This decrease occurred primarily in residential and land acquisition and development loans, and, to a lesser extent, commercial construction loans. Management attributes these decreases to general declines in demand for housing, particularly in three of our markets dependent upon resort and second home communities, and the movement of lower quality loans out of the loan portfolio through charge-off, pay-off or foreclosure.

Other consumer loans of $166 million as of September 30, 2010 decreased $30 million, or 15.2%, from $195 million as of December 31, 2009, primarily due to the third quarter 2010 sale of student loans totaling $25 million.

Management attributes the remaining decrease in total loans to the continuing impact of the uncertain economic conditions on loan demand in the Companys market areas, and to a lesser extent, the movement of lower quality loans out of the loan portfolio through loan charge-off or foreclosure.

Non-performing assets increased $74 million, or 45.5%, to $237 million, or 5.29% of total loans and OREO, as of September 30, 2010, from $163 million, or 3.57% of total loans and OREO, as of December 31, 2009. Difficult economic conditions continued to negatively impact businesses and consumers in our market areas, especially in three market areas with economies dependent upon resort and second home communities. These market areas include the Flathead area around Kalispell, Montana, the Gallatin Valley area around Bozeman, Montana and the Jackson, Wyoming market area. Residential and second home subdivisions in these market areas were overbuilt and these markets are now experiencing severely depressed real estate values and limited sales activity. The Flathead, Gallatin Valley and Jackson market areas accounted for approximately 55% of our non-performing assets as of September 30, 2010 versus only 21% of our total loans as of the same date. The continuing impact of current economic conditions is expected to result in further increases in non-performing assets in future quarters.

million as of December 31, 2009, primarily due to increases in non-accrual and restructured loans. Non-performing loans in the Flathead, Gallatin Valley and Jackson market areas increased to approximately 55% of total non-performing loans as of September 30, 2010, as compared to approximately 35% as of December 31, 2009.

Non-accrual loans of $174 million increased $59 million, or 51.5%, from $115 million as of December 31, 2009. Approximately 85% of loans with balances exceeding $1 million that were placed on non-accrual during the nine months ended September 30, 2010, were located in the Flathead, Gallatin Valley and Jackson market areas and were comprised primarily of commercial real estate and commercial construction loans.

Restructured loans increased to $27 million as of September 30, 2010, from $5 million as of December 31, 2009, primarily due to the loans of one commercial and five commercial real estate borrowers. Approximately 29% of the increase in restructured loans as of September 30, 2010, compared to December 31, 2009, occurred in the Flathead, Gallatin Valley and Jackson markets. As of September 30, 2010, 87% of the Companys restructured loans were performing in accordance with their modified terms.

The following table sets forth the allocation of our non-performing loans among our various loan categories as of the dates indicated:

In addition to the non-performing loans included in the non-performing loans table above, as of September 30, 2010 and December 31, 2009, we had potential problem loans of $279 million and $221 million, respectively. Potential problem loans consist of performing loans that have been internally risk classified due to uncertainties regarding the borrowers ability to continue to comply with the contractual repayment terms of the loans. Although these loans have been identified as potential non-performing loans, they may never become delinquent, non-performing or impaired. These loans are generally secured by commercial real estate or other assets, thus reducing the potential for loss should they become non-performing. Potential problem loans are considered in the determination of our allowance for loan losses. As of September 30, 2010, $8 million, or 3%, of our potential problem loans were more than 60 days past due, as compared to $2 million, or 1%, as of December 31, 2009.

OREO consists of real property acquired through foreclosure on the related collateral underlying defaulted loans. We record OREO at the lower of carrying value or fair value less estimated costs to sell. Estimated losses that result from the ongoing periodic valuation of these properties are charged to earnings in the period in which they are identified. OREO decreased $3 million, or 8.1%, to $35 million as of September 30, 2010, from $38 million as of December 31, 2009. As of September 30, 2010, approximately 64% of our OREO was located in the Flathead, Gallatin Valley and Jackson market areas. During the nine months ended September 30, 2010, we had additions to OREO of $17 million, wrote down the fair value of OREO properties by $5 million and sold OREO properties with a carrying value of $15 million. Approximately 68% of the OREO properties sold were located in the Flathead, Gallatin Valley and Jackson market areas. We recognized net gains of $179 thousand on sales of OREO during the nine months ended September 30, 2010.

Allowance for Loan Losses. In determining the allowance for loan losses, we estimate losses on specific loans, or groups of loans, where the probable loss can be identified and reasonably determined. The balance of the allowance for loan losses is based on internally assigned risk classifications of loans, historical loan loss rates, changes in the nature of the loan portfolio, overall portfolio quality, industry concentrations, delinquency trends, current economic factors and the estimated impact of current economic conditions on certain historical loan loss rates.

Although we believe that we have established our allowance for loan losses in accordance with accounting principles generally accepted in the United States and that the allowance for loan losses was adequate to provide for known and inherent losses in the portfolio at all times, future provisions will be subject to on-going evaluations of the risks in the loan portfolio. If the economy declines or asset quality deteriorates, material additional provisions could be required.

Investment Securities. We manage our investment portfolio to obtain the highest yield possible, while meeting our risk tolerance and liquidity guidelines and satisfying the pledging requirements for deposits of state and political subdivisions and securities sold under repurchase agreements. Investment securities increased $383 million, or 26.5%, to $1,829 million, or 25.0% of total assets, as of September 30, 2010 from $1,446 million, or 20.3% of total assets, as of December 31, 2009. Liquidity resulting from deposit growth combined with weak loan demand was primarily invested into securities. With lower market interest rates and the purchase of relatively short-term securities, the estimated duration of our investment securities portfolio decreased to 1.7 years as of September 30, 2010, from 2.2 years as of September 30, 2009.

We evaluate our investment portfolio quarterly for other-than-temporary declines in the market value of individual investment securities. This evaluation includes monitoring credit ratings; market, industry and corporate news; volatility in market prices; and, determining whether the market value of a security has been below its cost for an extended period of time. As of September 30, 2010, we had investment securities with fair values of $1 million that had been in a continuous loss position more than twelve months. Gross unrealized losses on these securities totaled $19 thousand as of September 30, 2010, and were primarily attributable to changes in interest rates. No impairment losses were recorded during the three and nine months ended September 30, 2010 and 2009.

Cash and Cash Equivalents. Cash and cash equivalents include cash on hand, amounts due from banks, federal funds sold for one day periods and interest bearing deposits in banks with original maturities of less than three months. IPO proceeds of $119 million, net of IPO costs and after the repayment of our variable rate term notes, were included in interest bearing deposits in banks as of September 30, 2010. Cash and cash equivalents decreased $81 million, or 13.0%, to $542 million as of September 30, 2010, from $623 million as of December 31, 2009. Increases in interest bearing deposits in banks due to IPO proceeds were offset by decreases in cash on hand and federal funds sold, as excess liquidity was invested in higher yielding investment securities.

Deposits. Our deposits consist of non-interest bearing and interest bearing demand, savings, individual retirement and time deposit accounts. Total deposits increased $78 million, or 1.3%, to $5,902 million as of September 30, 2010, from $5,824 million as of December 31, 2009. During the first nine months of 2010, there has been a slight shift in the mix of deposits from higher costing time deposits to lower costing savings and non-interest bearing deposits.

(1) Included in Time, other are Certificate of Deposit Account Registry Service, or CDAR, deposits of $166 million as of September 30, 2010 and $253 million as of December 31, 2009.

Long-Term Debt. Long-term debt decreased $36 million, or 48.9%, to $38 million as of September 30, 2010, from $73 million as of December 31, 2009 due to the early repayment of $34 million of variable rate term notes and, to a lesser extent, scheduled repayments of long-term Federal Home Loan Bank borrowings.

Capital Resources and Liquidity Management

Capital Resources. On March 5, 2010, our shareholders approved proposals to recapitalize our existing common stock. The recapitalization included a redesignation of existing common stock as Class B common stock with five votes per share, convertible into Class A common stock on a share for share basis; a four-for-one stock split of the Class B common stock; an increase in the authorized number of Class B common shares from 20,000,000 to 100,000,000; and the creation of a new class of common stock designated as Class A common stock, with one vote per share, with 100,000,000 shares authorized.

Stockholders equity is influenced primarily by earnings, dividends, sales of common stock and changes in the unrealized holding gains or losses, net of taxes, on available-for-sale investment securities. Stockholders equity increased $170 million, or 29.6%, to $745 million as of September 30, 2010, from $574 million as of December 31, 2009, primarily due to the completion of our IPO of Class A common stock, which closed on March 29, 2010 and included the issuance of 11,500,000 Class A common stock shares at a price of $14.50 per share. We received net proceeds of $153 million from the offering, after deducting underwriting discounts, commissions and other offering expenses of $14 million. The remaining increase in stockholders equity was largely attributable to other comprehensive income, primarily unrealized gains and losses on available-for-sale investment securities.

On September 24, 2010, we declared a quarterly dividend to common stockholders of $0.1125 per share that was paid on October 15, 2010 to shareholders of record as of October 4, 2010. During the first nine months of 2010, we paid aggregate cash dividends of $13.1 million, or $0.3375 per share, to common stockholders and $2.6 million to preferred stockholders, as compared to aggregate cash dividends of $12.2 million, or $0.3875 per share, to common stockholders and $2.6 million to preferred stockholders during the same period in 2009.

Pursuant to the Federal Deposit Insurance Corporation Improvement Act, the Federal Reserve and FDIC have adopted regulations setting forth a five-tier system for measuring the capital adequacy of the financial institutions they supervise. At September 30, 2010 and December 31, 2009, the Bank had capital levels that, in all cases, exceeded the well-capitalized guidelines. As of September 30, 2010, we had consolidated leverage, tier 1 and total risk-based capital ratios of 9.38%, 13.22% and 15.18%, respectively, as compared to 7.30%, 9.74% and 11.68%, respectively, as of December 31, 2009. The significant increases in our capital ratios reflect the impact of additional capital raised from our IPO in March 2010.

Liquidity. Liquidity measures our ability to meet current and future cash flow needs on a timely basis and at a reasonable cost. We manage our liquidity position to meet the daily cash flow needs of customers, while maintaining an appropriate balance between assets and liabilities to meet the return on investment objectives of our shareholders. Our liquidity position is supported by management of liquid assets and liabilities and access to alternative sources of funds. Liquid assets include cash, interest bearing deposits in banks, federal funds sold, available-for-sale investment securities and maturing or prepaying balances in our held-to-maturity investment and loan portfolios. Liquid liabilities include core deposits, federal funds purchased, securities sold under repurchase agreements and borrowings. Other sources of liquidity include the sale of loans, the ability to acquire additional national market, non-core deposits, the issuance of additional collateralized borrowings such as FHLB advances, the issuance of debt securities, additional borrowings through the Federal Reserves discount window and the issuance of preferred or common securities.

Our short-term and long-term liquidity requirements are primarily to fund on-going operations,including payment of

Folio 34 /Folio

PAGEBREAK

Table of Contents

interest on deposits and debt, extensions of credit to borrowers, capital expenditures and shareholder dividends. These liquidity requirements are met primarily through cash flow from operations, redeployment of prepaying and maturing balances in our loan and investment portfolios, debt financing and increases in customer deposits.

As a holding company, we are a corporation separate and apart from the Bank and, therefore, we provide for our own liquidity. Our main sources of funding include management fees and dividends declared and paid by the Bank and access to capital markets. There are statutory and regulatory limitations that affect the ability of our subsidiary bank to pay dividends to us. Management believes that such limitations will not impact our ability to meet our ongoing short-term cash obligations.

Asset Liability Management

The goal of asset liability management is the prudent control of market risk, liquidity and capital. Asset liability management is governed by policies, goals and objectives adopted and reviewed by the Banks board of directors. The Bank board delegates its responsibility for development of asset liability management strategies to achieve these goals and objectives to the Asset Liability Committee, or ALCO, which is comprised of members of senior management, including four Bank board members.

We target a mix of interest earning assets and interest bearing liabilities such that no more than 5.0% of the net interest margin will be at risk over a one-year period should short-term interest rates shift up or down 2%. As of September 30, 2010, our income simulation model predicted net interest income would decrease $3.1 million, or 1.2%, assuming a 2% increase in short-term and long-term interest rates over a twelve-month period. This scenario predicts that our funding sources will reprice faster than our interest earning assets. During 2009, we began to implement interest rate floors on certain variable rate loans. Interest rate floors mitigate benefits obtained in a rising interest rate environment until such time as market interest rates exceed the interest rate floors established. We do not engage in derivatives or hedging activities to manage our interest rate risk.

We did not simulate a decrease in interest rates due to the extremely low rate environment as of September 30, 2010. Prime rate has historically been set at a rate of 300 basis points over the targeted federal funds rate, which is currently set between 0 and 25 basis points. Our income simulation model has an assumption that prime will continue to be set at a rate of 300 basis points over the targeted federal funds rate. Additionally, rates that are currently below 2% are modeled not to fall below 0% with an overall decrease of 2% in interest rates. In a declining rate environment, our income simulation model predicts our net interest income and net interest rate spread will decrease and our net interest margin will compress because interest expense will not decrease in direct proportion to a simulated downward shift in interest rates.

CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining effective disclosure controls and procedures, as defined under Rules 13a-15(e) and 15d-15(e) of the Exchange Act. As of September 30, 2010, an evaluation was performed, under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of September 30, 2010, were effective in ensuring that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods required by the SECs rules and forms, and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting for the quarter ended September 30, 2010, that have materially affected, or are reasonably likely to materially affect, such control.

Limitations on Controls and Procedures

The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the soundness of our systems, the possibility of human error, and the risk of fraud. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions and the risk that the degree of compliance with policies or procedures may deteriorate over time. Because of these limitations, any system of disclosure controls and procedures or internal control over financial reporting may not be successful in preventing all errors or fraud or in making all material information known in a timely manner to the appropriate levels of management.
