Notes to Unaudited Condensed Consolidated Financial Statements
Note 1. Nature of Operations and Summary of Significant Accounting Policies
General
Glacier Bancorp, Inc. (“Company”) is a Montana corporation headquartered in Kalispell, Montana. The Company provides a full range of banking services to individual and corporate customers in Montana, Idaho, Wyoming, Colorado, Utah and Washington through eleven divisions of its wholly-owned bank subsidiary, Glacier Bank (“Bank”). The Company offers a wide range of banking products and services, including transaction and savings deposits, real estate, commercial, agriculture and consumer loans, mortgage origination services, and retail brokerage services. The Company serves individuals, small to medium-sized businesses, community organizations and public entities.
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 March 31, 2013, the results of operations and comprehensive income for the three month periods ended March 31, 2013 and 2012, and changes in stockholders’ equity and cash flows for the three month periods ended March 31, 2013 and 2012. The condensed consolidated statement of financial condition of the Company as of December 31, 2012 has been derived from the audited consolidated statements of the Company as of that date.
The accompanying unaudited 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 (“GAAP”) for complete financial statements. These unaudited 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, 2012. Operating results for the three months ended March 31, 2013 are not necessarily indicative of the results anticipated for the year ending December 31, 2013.
The Company is a defendant in legal proceedings arising in the normal course of business. In the opinion of management, the disposition of pending litigation will not have a material affect on the Company's consolidated financial position, results of operations or liquidity.
Material estimates that are particularly susceptible to significant change include the determination of the allowance for loan and lease losses (“ALLL” or “allowance”) and the valuations related to investments and real estate acquired in connection with foreclosures or in satisfaction of loans. For 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 third parties.
Principles of Consolidation
The consolidated financial statements of the Company include the parent holding company and the Bank. The Bank consists of eleven bank divisions, each of which operate under separate names, management teams and directors. The Company considers the Bank to be its sole operating segment as the Bank 1) engages in similar bank business activity from which it earns revenues and incurs expenses, 2) the operating results of the Bank are regularly reviewed by the Chief Executive Officer (i.e., the chief operating decision maker) who makes decisions about resources to be allocated to the Bank, and 3) financial information is available for the Bank. All significant inter-company transactions have been eliminated in consolidation.
The Company formed GBCI Other Real Estate (“GORE”) to isolate certain bank foreclosed properties for legal protection and administrative purposes and the remaining properties are currently held for sale. GORE is included in the Bank operating segment due to its insignificant activity.
The Company owns the following trust subsidiaries, each of which issued trust preferred securities as Tier 1 capital instruments: Glacier Capital Trust II, Glacier Capital Trust III, Glacier Capital Trust IV, Citizens (ID) Statutory Trust I, Bank of the San Juans Bancorporation Trust I, First Company Statutory Trust 2001 and First Company Statutory Trust 2003. The trust subsidiaries are not included in the Company’s consolidated financial statements.

Recent and Pending Acquisitions
On February 25, 2013, the Company announced the signing of a definitive agreement to acquire First State Bank, a community bank based in Wheatland, Wyoming. First State Bank provides community banking services to individuals and businesses from banking offices in Wheatland, Torrington and Guernsey, Wyoming. Upon closing of the transaction, which is anticipated to take place in the second quarter of 2013, First State Bank will be merged into the Bank and operate as a separate bank division doing business under its existing name.
On March 27, 2013, the Company announced the signing of a definitive agreement to acquire North Cascades National Bank, a community bank based in Chelan, Washington. North Cascades National Bank provides community banking services to individuals and businesses in central Washington, with banking offices located in Chelan, Wenatchee, East Wenatchee, Omak, Brewster, Twisp, Okanagan, Grand Coulee and Waterville, Washington. Upon closing of the transaction, which is anticipated to take place in the third quarter of 2013, North Cascades National Bank will be merged into the Bank and operate as a separate bank division doing business under its existing name.
Variable Interest Entities
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 variable interest entities (“VIE”).
The following table summarizes the carrying amounts of the VIE’s assets and liabilities included in the Company’s consolidated financial statements at March 31, 2013 and December 31, 2012:

| March 31, 2013 |  | December 31, 2012

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.
Loans Receivable
Loans that are intended to be held-to-maturity are reported at the unpaid principal balance less charge-offs and adjusted for deferred fees and costs on originated loans and unamortized premiums or discounts on acquired loans. Interest income is recognized using the interest method and includes discount accretion and premium amortization on acquired loans and net loan fees on originated loans which are amortized over the expected life of the loans using a method that approximates the level-yield interest method. The Company’s loan segments, which are based on the purpose of the loan, include residential real estate, commercial, and consumer loans. The Company’s loan classes, a further disaggregation of segments, include residential real estate loans (residential real estate segment), commercial real estate and other commercial loans (commercial segment), and home equity and other consumer loans (consumer segment).

Table of Contents
Loans that are thirty days or more past due based on payments received and applied to the loan are considered delinquent. Loans are designated non-accrual and the accrual of interest is discontinued when the collection of the contractual principal or interest is unlikely. A loan is typically placed on non-accrual when principal or interest is due and has remained unpaid for ninety days or more. When a loan is placed on non-accrual status, interest previously accrued but not collected is reversed against current period interest income. Subsequent payments are applied to the outstanding principal balance if doubt remains as to the ultimate collectability of the loan. Interest accruals are not resumed on partially charged-off impaired loans. For other loans on nonaccrual, interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to both principal and interest.
The Company recognizes that while borrowers may experience deterioration in their financial condition, many continue to be creditworthy customers who have the willingness and capacity for debt repayment. In determining whether non-restructured or unimpaired loans issued to a single or related party group of borrowers should continue to accrue interest when the borrower has other loans that are impaired or troubled debt restructurings ("TDR"), the Company on a quarterly or more frequent basis performs an updated and comprehensive assessment of the willingness and capacity of the borrowers to timely and ultimately repay their total debt obligations, including contingent obligations. Such analysis takes into account current financial information about the borrowers and financially responsible guarantors, if any, including for example:

• | analysis of global, i.e., aggregate debt service for total debt obligations;

• | assessment of the value and security protection of collateral pledged using current market conditions and alternative market assumptions across a variety of potential future situations; and

• | loan structures and related covenants.

The Company considers impaired loans to be the primary credit quality indicator for monitoring the credit quality of the loan portfolio. Loans are designated impaired when, based upon current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement and therefore, the Company has serious doubts as to the ability of such borrowers to fulfill the contractual obligation. Impaired loans include non-performing loans (i.e., non-accrual loans and accruing loans ninety days or more past due) and accruing loans under ninety days past due where it is probable payments will not be received according to the loan agreement (e.g., TDR). Interest income on accruing impaired loans is recognized using the interest method. The Company measures impairment on a loan-by-loan basis in the same manner for each class within the loan portfolio. An insignificant delay or shortfall in the amounts of payments would not cause a loan or lease to be considered impaired. The Company determines the significance of payment delays and shortfalls on a case-by-case basis, taking into consideration all of the facts and circumstances surrounding the loan and the borrower, including the length and reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest due.
A restructured loan is considered a TDR if the creditor, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would not otherwise consider. A TDR loan is considered an impaired loan and a specific valuation allowance is established when the fair value of the collateral-dependent loan or present value of the loan's expected future cash flows (discounted at the loan's effective interest rate based on the original contractual rate) is lower than the carrying value of the impaired loan. The Company made the following types of loan modifications, some of which were considered a TDR:

• | Reduction of the stated interest rate for the remaining term of the debt;

• | Extension of the maturity date(s) at a stated rate of interest lower than the current market rate for newly originated debt having similar risk characteristics; and

• | Reduction of the face amount of the debt as stated in the debt agreements.

Allowance for Loan and Lease Losses
Based upon management’s analysis of the Company’s loan portfolio, the balance of the ALLL is an estimate of probable credit losses known and inherent within the Bank's loan portfolio as of the date of the consolidated financial statements. The ALLL is analyzed at the loan class level and is maintained within a range of estimated losses. Determining the adequacy of the ALLL involves a high degree of judgment and is inevitably imprecise as the risk of loss is difficult to quantify. The determination of the ALLL and the related provision for loan losses is a critical accounting estimate that involves management’s judgments about all known relevant internal and external environmental factors that affect loan losses. The balance of the ALLL is highly dependent upon management’s evaluations of borrowers’ current and prospective performance, appraisals and other variables affecting the quality of the loan portfolio. Individually significant loans and major lending areas are reviewed periodically to determine potential problems at an early date. Changes in management’s estimates and assumptions are reasonably possible and may have a material impact upon the Company’s consolidated financial statements, results of operations or capital.

The ALLL consists of a specific valuation allowance component and a general valuation allowance component. The specific component relates to loans that are determined to be impaired and individually evaluated for impairment. The Company measures impairment on a loan-by-loan basis based on the present value of expected future cash flows discounted at the loan’s effective interest rate, except when it is determined that repayment of the loan is expected to be provided solely by the underlying collateral. For impairment based on expected future cash flows, the Company considers all information available as of a measurement date, including past events, current conditions, potential prepayments, and estimated cost to sell when such costs are expected to reduce the cash flows available to repay or otherwise satisfy the loan. For alternative ranges of cash flows, the likelihood of the possible outcomes is considered in determining the best estimate of expected future cash flows. The effective interest rate for a loan restructured in a TDR is based on the original contractual rate. For collateral-dependent loans and real estate loans for which foreclosure or a deed-in-lieu of foreclosure is probable, impairment is measured by the fair value of the collateral, less estimated cost to sell. The fair value of the collateral is determined primarily based upon appraisal or evaluation of the underlying real property value.
The general valuation allowance component relates to probable credit losses inherent in the balance of the loan portfolio based on historical loss experience, adjusted for changes in trends and conditions of qualitative or environmental factors. The historical loss experience is based on the previous twelve quarters loss experience by loan class adjusted for risk characteristics in the existing loan portfolio. The same trends and conditions are evaluated for each class within the loan portfolio; however, the risk characteristics are weighted separately at the individual class level based on the Company's judgment and experience.
The changes in trends and conditions of certain items include the following:

• | Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses;

• | Changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments;

• | Changes in the nature and volume of the portfolio and in the terms of loans;

• | Changes in experience, ability, and depth of lending management and other relevant staff;

• | Changes in the volume and severity of past due and nonaccrual loans;

• | Changes in the quality of the Company’s loan review system;

• | Changes in the value of underlying collateral for collateral-dependent loans;

• | The existence and effect of any concentrations of credit, and changes in the level of such concentrations; and

• | The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the Company’s existing portfolio.

The ALLL is increased by provisions for loan losses which are charged to expense. The portions of loan balances determined by management to be uncollectible are charged-off as a reduction of the ALLL. Recoveries of amounts previously charged-off are credited as an increase to the ALLL. The Company's charge-off policy is consistent with bank regulatory standards. Consumer loans generally are charged off when the loan becomes over 120 days delinquent. Real estate acquired as a result of foreclosure or by deed-in-lieu of foreclosure is classified as real estate owned until such time as it is sold.
Impact of Recent Authoritative Accounting Guidance
The Accounting Standards Codification™ (“ASC”) is the Financial Accounting Standards Board’s (“FASB”) officially recognized source of authoritative 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 the Company as an SEC registrant. All other accounting literature is non-authoritative.
In June 2011, FASB amended FASB ASC Topic 220, Comprehensive Income. The amendment provides 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. Accounting Standards Update ("ASU") No. 2011-12, Comprehensive Income (Topic 220) deferred the specific requirement of the amendment to present items that are reclassified from accumulated other comprehensive income to net income separately with their respective components of net income and other comprehensive income. The amendments were effective retrospectively during interim and annual periods beginning after December 15, 2011. ASU No. 2013-2, Comprehensive Income (Topic 220) reversed the deferment of ASU 2011-12 and will be effective prospectively for reporting periods beginning after December 15, 2012 and early adoption is permitted. The Company early adopted ASU No. 2013-2 as of December 31, 2012. The Company has evaluated the impact of the adoption of these amendments and determined there was not a material effect on the Company's financial position or results of operations.

For the three months ended March 31, 2013 and 2012, the majority of TDRs occurring in most loan classes was a result of an extension of the maturity date which aggregated 43 percent and 28 percent, respectively, of total TDRs. For commercial real estate, the class with the largest dollar amount of TDRs, approximately 29 percent and 20 percent, respectively, was a result of an extension of the maturity date and 30 percent and 3 percent, respectively, was due to a combination of an interest rate reduction, extension of the maturity date, or reduction in the face amount.
In addition to the TDRs that occurred during the period provided in the preceding table, the Company had TDRs with pre-modification loan balances of $7,186,000 and $15,550,000 for the three months ended March 31, 2013 and 2012, respectively, for which other real estate owned ("OREO") was received in full or partial satisfaction of the loans. The majority of such TDRs for both periods was in commercial real estate.
Note 4. Goodwill
The Company performed its annual goodwill impairment test during the third quarter of 2012 and determined the fair value of the aggregated reporting units exceeded the carrying value, such that the Company's goodwill was not considered impaired. Given there were no events or circumstances that occurred since the third quarter 2012 that would more-likely-than-not reduce the fair value of the aggregated reporting units below the carrying value, the Company did not perform interim testing at March 31, 2013. However, further adverse ch anges in the economic environment, operations of the aggregated reporting units, or other factors could result in the decline in the fair value of the aggregated reporting units which could result in a goodwill impairment in the future.
There were no changes in the carrying value of goodwill during the three months ended March 31, 2013 and 2012. The gross carrying value of goodwill and the accumulated impairment charge consists of the following:

(Dollars in thousands) | March 31, 2013 |  | December 31, 2012

Note 5. Derivatives and Hedging Activities
As of March 31, 2013, the Company’s interest rate derivative financial instruments were designated as cash flow hedges and are summarized as follows:

(Dollars in thousands) | Forecasted Notional Amount |  | Variable Interest Rate 1 |  | Fixed Interest Rate 1 |  | Term 2
Interest rate swap | $ | 160,000 |  |  | 3 month LIBOR |  | 3.378 | % |  | Oct. 21, 2014 - Oct. 21, 2021
Interest rate swap | 100,000 |  |  | 3 month LIBOR |  | 2.498 | % |  | Nov 30, 2015 - Nov. 30, 2022

__________
1 The Company pays the fixed interest rate and the counterparties pay the Company the variable interest rate.
2 No cash will be exchanged prior to the term.
The hedging strategy converts the LIBOR based variable interest rate on forecasted borrowings to a fixed interest rate, thereby protecting the Company from floating interest rate variability.
The following table summarizes the fair value of the Company’s interest rate derivative financial instruments:

|  |  | Fair Value
(Dollars in thousands) | Balance Sheet Location |  | March 31, 2013 |  | December 31, 2012
Interest rate swap | Other liabilities |  | $ | 14,080 |  |  | 16,832 |

Pursuant to the interest rate swap agreements, the Company pledged collateral to the counterparties in the form of investment securities totaling $14,043,000 at March 31, 2013. There was $0 collateral pledged from the counterparties to the Company as of March 31, 2013. There is the possibility that the Company may need to pledge additional collateral in the future if there were further declines in the fair value.
Note 6. Accumulated Other Comprehensive Income
The components of accumulated other comprehensive income, included in stockholders’ equity, are as follows:

Note 7. Earnings Per Share
Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period presented. Diluted earnings per share is computed by including the net increase in shares as if dilutive outstanding stock options were exercised, using the treasury stock method.
Basic and diluted earnings per share has been computed based on the following:

| Three Months ended
(Dollars in thousands, except per share data) | March 31, 2013 |  | March 31, 2012
Net income available to common stockholders, basic and diluted | $ | 20,768 |  |  | 16,333 |
Average outstanding shares - basic | 71,965,665 |  |  | 71,915,073 |
Add: dilutive stock options and awards | 47,512 |  |  | 57 |
Average outstanding shares - diluted | 72,013,177 |  |  | 71,915,130 |
Basic earnings per share | $ | 0.29 |  |  | 0.23 |
Diluted earnings per share | $ | 0.29 |  |  | 0.23 |

There were 152,559 and 1,048,184 options excluded from the diluted average outstanding share calculation for the three months ended March 31, 2013 and 2012, respectively, due to the option exercise price exceeding the market price of the Company’s common stock.
Note 8. Fair Value of Assets and Liabilities
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. There is a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are as follows:
Level 1 Quoted prices in active markets for identical assets or liabilities

Level 2 | Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities

Level 3 | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities

Transfers in and out of Level 1 (quoted prices in active markets), Level 2 (significant other observable inputs) and Level 3 (significant unobservable inputs) are recognized on the actual transfer date. There were no transfers between fair value hierarchy levels during the three month periods ended March 31, 2013 and 2012.
Recurring Measurements
The following is a description of the inputs and valuation methodologies used for assets and liabilities measured at fair value on a recurring basis, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy. There have been no significant changes in the valuation techniques during the period ended March 31, 2013.
Investment securities: fair value for available-for-sale securities is estimated by obtaining quoted market prices for identical assets, where available. If such prices are not available, fair value is based on independent asset pricing services and models, the inputs of which are market-based or independently sourced market parameters, including but not limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections, and cash flows. Such securities are classified in Level 2 of the valuation hierarchy. Where Level 1 or Level 2 inputs are not available, such securities are classified as Level 3 within the hierarchy.

Table of Contents
Fair value determinations of investment securities are the responsibility of the Company’s corporate accounting department. The Company contracts with independent third party pricing vendors to generate fair value estimates on a monthly basis. The Company reviews the vendors’ inputs for fair value estimates and the recommended assignments of levels within the fair value hierarchy. The review includes the extent to which markets for investment securities are determined to have limited or no activity, or are judged to be active markets. The Company reviews the extent to which observable and unobservable inputs are used as well as the appropriateness of the underlying assumptions about risk that a market participant would use in active markets, with adjustments for limited or inactive markets. In considering the inputs to the fair value estimates, the Company places less reliance on quotes that are judged to not reflect orderly transactions, or are non-binding indications. The Company makes independent inquiries of other knowledgeable parties in testing the reliability of the inputs, including consideration for illiquidity, credit risk, and cash flow estimates. In assessing credit risk, the Company reviews payment performance, collateral adequacy, credit rating histories, and issuers’ financial statements with follow-up discussion with issuers. For those markets determined to be inactive, the valuation techniques used are models for which management verifies that discount rates are appropriately adjusted to reflect illiquidity and credit risk. The Company also independently obtains cash flow estimates that are stressed at levels that exceed those used by the independent third party pricing vendors.
Interest rate swap derivative agreements: fair values for interest rate swap derivative agreements are based upon the estimated amounts to settle the contracts considering current interest rates and are calculated using discounted cash flows that are observable or that can be corroborated by observable market data and, therefore, are classified within Level 2 of the valuation hierarchy. The inputs used to determine fair value include the 3 month LIBOR forward curve to estimate variable rate cash inflows and the spot LIBOR curve to estimate the discount rate. The estimated variable rate cash inflows are compared to the fixed rate outflows and such difference is discounted to a present value to estimate the fair value of the interest rate swaps. The Company also obtains and compares the reasonableness of the pricing from an independent party.

Non-recurring Measurements
The following is a description of the inputs and valuation methodologies used for assets recorded at fair value on a non-recurring basis, as well as the general classification of such assets pursuant to the valuation hierarchy. There have been no significant changes in the valuation techniques during the period ended March 31, 2013.
Other real estate owned: OREO is carried at the lower of fair value at acquisition date or estimated fair value, less estimated cost to sell. Estimated fair value of OREO is based on appraisals or evaluations (new or updated). OREO is classified within Level 3 of the fair value hierarchy.
Collateral-dependent impaired loans, net of ALLL: loans included in the Company’s loan portfolio for which it is probable that the Company will not collect all principal and interest due according to contractual terms are considered impaired. Estimated fair value of collateral-dependent impaired loans is based on the fair value of the collateral, less estimated cost to sell. Collateral-dependent impaired loans are classified within Level 3 of the fair value hierarchy.
The Company’s credit departments review appraisals for OREO and collateral-dependent loans, giving consideration to the highest and best use of the collateral. The appraisal or evaluation (new or updated) is considered the starting point for determining fair value. The valuation techniques used in preparing appraisals or evaluations (new or updated) include the cost approach, income approach, sales comparison approach, or a combination of the preceding valuation techniques. The key inputs used to determine the fair value of the collateral-dependent loans and OREO include selling costs, discounted cash flow rate or capitalization rate, and adjustment to comparables. Valuations and significant inputs obtained by independent sources are reviewed by the Company for accuracy and reasonableness. The Company also considers other factors and events in the environment that may affect the fair value. The appraisals or evaluations (new or updated) are reviewed at least quarterly and more frequently based on current market conditions, including deterioration in a borrower’s financial condition and when property values may be subject to significant volatility. After review and acceptance of the collateral appraisal or evaluation (new or updated), adjustments to the impaired loan or OREO may occur. The Company generally obtains appraisals or evaluations (new or updated) annually.

Fair Value of Financial Instruments
The following is a description of the methods used to estimate the fair value of all other assets and liabilities recognized at amounts other than fair value.
Cash and cash equivalents: fair value is estimated at book value.
Loans held for sale: fair value is estimated at book value.
Loans receivable, net of ALLL: fair value is estimated by discounting the future cash flows using the rates at which similar notes would be written for the same remaining maturities. The market rates used are based on current rates the Company would impose for similar loans and reflect a market participant assumption about risks associated with non-performance, illiquidity, and the structure and term of the loans along with local economic and market conditions. Estimated fair value of impaired loans is based on the fair value of the collateral, less estimated cost to sell, or the present value of the loan’s expected future cash flows (discounted at the loan’s effective interest rate). All impaired loans are classified as Level 3 and all other loans are classified as Level 2 within the hierarchy.
Accrued interest receivable: fair value is estimated at book value.
Non-marketable equity securities: fair value is estimated at book value due to restrictions that limit the sale or transfer of such securities.
Deposits: fair value of term deposits is estimated by discounting the future cash flows using rates of similar deposits with similar maturities. The market rates used were obtained from a knowledgeable independent third party and reviewed by the Company. The rates were the average of current rates offered by the Company’s local competitors. The estimated fair value of demand, NOW, savings, and money market deposits is the book value since rates are regularly adjusted to market rates and transactions are executed at book value daily. Therefore, such deposits are classified in Level 1 of the valuation hierarchy. Certificate accounts and wholesale deposits are classified as Level 2 within the hierarchy.
Federal Home Loan Bank ("FHLB") advances: fair value of non-callable FHLB advances is estimated by discounting the future cash flows using rates of similar advances with similar maturities. Such rates were obtained from current rates offered by FHLB. The estimated fair value of callable FHLB advances was obtained from FHLB and the model was reviewed by the Company through discussions with FHLB.
Securities sold under agreements to repurchase ("repurchase agreements") and other borrowed funds: fair value of term repurchase agreements and other term borrowings is estimated based on current repurchase rates and borrowing rates currently available to the Company for repurchases and borrowings with similar terms and maturities. The estimated fair value for overnight repurchase agreements and other borrowings is book value.
Subordinated debentures: fair value of the subordinated debt is estimated by discounting the estimated future cash flows using current estimated market rates. The market rates used were averages of currently traded trust preferred securities with similar characteristics to the Company’s issuances and obtained from an independent third party.
Accrued interest payable: fair value is estimated at book value.
Off-balance sheet financial instruments: commitments to extend credit and letters of credit represent the principal categories of off-balance sheet financial instruments. Rates for these commitments are set at time of loan closing, such that no adjustment is necessary to reflect these commitments at market value. The Company has an insignificant amount of off-balance sheet financial instruments.

Item 2. | Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion is intended to provide a more comprehensive review of the Company’s operating results and financial condition than can be obtained from reading the Consolidated Financial Statements alone. The discussion should be read in conjunction with the Consolidated Financial Statements and the notes thereto included in “Part I. Item 1. Financial Statements.”
FORWARD-LOOKING STATEMENTS
This Form 10-Q may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to, statements about management’s plans, objectives, expectations and intentions that are not historical facts, and other statements identified by words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “should,” “projects,” “seeks,” “estimates” or words of similar meaning. These forward-looking statements are based on current beliefs and expectations of management and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond the Company’s control. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change. In addition to the factors set forth in the sections titled “Risk Factors,” “Business” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, as applicable, in this report and the Annual Report on Form 10-K for the year ended December 31, 2012 (the “2012 Annual Report”), the following factors, among others, could cause actual results to differ materially from the anticipated results:

• | the risks associated with lending and potential adverse changes of the credit quality of loans in the Company’s portfolio, including as a result of a slow recovery in the housing and real estate markets in its geographic areas;

• | increased loan delinquency rates;

• | the risks presented by a slow economic recovery, which could adversely affect credit quality, loan collateral values, other real estate owned values, investment values, liquidity and capital levels, dividends and loan originations;

• | changes in market interest rates, which could adversely affect the Company’s net interest income and profitability;

• | legislative or regulatory changes that adversely affect the Company’s business, ability to complete pending or prospective future acquisitions, limit certain sources of revenue, or increase cost of operations;

• | costs or difficulties related to the completion and integration of acquisitions;

• | the goodwill the Company has recorded in connection with acquisitions could become additionally impaired, which may have an adverse impact on earnings and capital;

• | reduced demand for banking products and services;

• | the risks presented by public stock market volatility, which could adversely affect the market price of the Company's common stock and the ability to raise additional capital in the future;

• | competition from other financial services companies in the Company's markets;

• | loss of services from the CEO and senior management team;

• | potential interruption or breach in security of the Company's systems; and

• | the Company’s success in managing risks involved in the foregoing.

Please take into account that forward-looking statements speak only as of the date of this Form 10-Q. The Company does not undertake any obligation to publicly correct or update any forward-looking statement if it later becomes aware that actual results are likely to differ materially from those expressed in such forward-looking statement.

Investment securities decreased $25.0 million, or 1 percent, during the current quarter and increased $419 million, or 13 percent, from March 31, 2012. The Company continued to purchase investment securities during the current quarter to offset the slow loan growth, however, the Company purchased investment securities (net of principal paydowns) at a slower pace than in the past several quarters. Additionally, the Company has moderately shifted the mix of investment securities through purchase activity in an effort to lessen the impact of the elevated premium amortization on collateralized mortgage obligation ("CMO") securities. The investment securities purchased during the current quarter included U.S. Agency mortgage-backed securities, U.S. Agency CMOs, corporate and municipal bonds. Investment securities represent 48 percent of total assets at March 31, 2013 and December 31, 2012 versus 45 percent at March 31, 2012.

Net Interest Income
The current quarter net interest income of $50.5 million decreased $1.0 million, or 2 percent, over the prior quarter and decreased $7.8 million, or 13 percent, over the prior year first quarter. The current quarter interest income of $58.0 million decreased $1.7 million, or 3 percent, over the prior quarter as a result of the decrease in interest income on the loan portfolio. Included in the current quarter interest income was $21.4 million of premium amortization (net of discount accretion) on investment securities compared to $23.3 million in the prior quarter. The decrease of $1.9 million in premium amortization (net of discount accretion) on investment securities during the current quarter was the first quarterly decrease in seven quarters. The current quarter interest income decreased $9.9 million, or 15 percent, over the prior year first quarter primarily due to an $8.1 million increase in premium amortization (net of discount accretion) on investment securities coupled with a decrease of $4.2 million in loan interest income from the prior year first quarter. The current quarter decrease in interest expense of $707 thousand, or 9 percent, from the prior quarter and the decrease of $2.1 million, or 22 percent, in interest expense from the prior year first quarter was the result of a decrease in interest rates on deposits and a decrease in the amount of borrowings. The cost of total funding (including non-interest bearing deposits) for the current quarter was 46 basis points compared to 48 basis points for the prior quarter and 61 basis points for the prior year first quarter.
The current quarter net interest margin as a percentage of earning assets, on a tax-equivalent basis, was 3.14 percent, an increase of 9 basis points from the prior quarter net interest margin of 3.05 percent. The increase in the net interest margin during the current quarter was the first increase in seven quarters and was primarily attributable to the increased yield on the investment securities. Of the 13 basis points increase in yield on the investment securities, 12 basis points was due to the decrease in premium amortization. The premium amortization in the current quarter accounted for a 123 basis points reduction in the net interest margin compared to a 128 basis points reduction in the prior quarter and 79 basis points reduction in the net interest margin in the prior year first quarter.
Non-interest Income
Non-interest income for the current quarter totaled $23.0 million, a decrease of $2.4 million over the prior quarter and an increase of $2.6 million over the same quarter last year. Service charge fee income decreased $1.2 million, or 9 percent, from the prior quarter as a result of seasonal activity and fewer days in the quarter. Service charge fee income increased $237 thousand, or 2 percent, from the prior year first quarter. Gain on sale of loans of $9.1 million for the current quarter remained at historically high levels, but decreased $75 thousand, or 1 percent, from the prior quarter. Compared to the prior year period, the Company recorded a $2.3 million increase on the gain on sale of loans. Other income of $2.3 million for the current quarter decreased $1.1 million, or 31 percent, from the prior quarter primarily a result of decreases in income related to OREO and gains on the sale of bank assets. Included in other income was operating revenue of $62 thousand from OREO and gains of $664 thousand on the sale of OREO, which totaled $726 thousand for the current quarter compared to $910 thousand for the prior quarter and $528 thousand for the prior year first quarter.

Non-interest expense of $43.4 million for the current quarter decreased by $4.6 million, or 10 percent, from the prior quarter and decreased by $5.6 million, or 11 percent, from the prior year first quarter primarily driven by the decrease in OREO. OREO expense decreased $2.7 million, or 75 percent, from the prior quarter and decreased $5.9 million, or 87 percent, from the prior year first quarter. The current quarter OREO expense of $884 thousand included $422 thousand of operating expense, $227 thousand of fair value write-downs, and $235 thousand of loss on sale of other real estate owned. OREO expense will fluctuate as the Company continues to work through non-performing loans and dispose of foreclosed properties. Compensation and employee benefits increased by $494 thousand, or 2 percent, from the prior quarter and increased $1.0 million, or 4 percent, from the prior year first quarter. Other expense decreased by $2.2 million, or 21 percent, from the prior quarter and decreased by $198 thousand, or 2 percent, from the prior year first quarter and was the result of changes in several miscellaneous categories.

Efficiency Ratio
The efficiency ratio for the current quarter was 55 percent compared to 51 percent for the prior year first quarter. Although there was an increase in non-interest income during the current quarter, it was not enough to offset the decrease in net interest income.
Provision for Loan Losses
The following table summarizes the provision for loan losses, net charge-offs and select ratios relating to the provision for loan losses for the previous eight quarters:

(Dollars in thousands) | Provision for Loan Losses |  | Net Charge-Offs |  | ALLL as a Percent of Loans |  | Accruing Loans 30-89 Days Past Due as a Percent of Loans |  | Non-Performing Assets to Total Sub-sidiary Assets
First quarter 2013 | $ | 2,100 |  |  | 2,119 |  |  | 3.84 | % |  | 0.95 | % |  | 1.79 | %

Second quarter 2011 | 19,150 |  |  | 20,184 |  |  | 3.88 | % |  | 1.14 | % |  | 3.68 | %

Net charged-off loans of $2.1 million during the current quarter decreased $6.0 million, or 74 percent, compared to the prior quarter. Although there has been fluctuation in the amount of charged-off loans the past several quarters, the Company continues to see overall better results as credit trends improve. The current quarter provision for loan losses was $2.1 million, which decreased $175 thousand compared to the $2.3 million provision for loan losses for the prior quarter and decreased $6.5 million from the first quarter of the prior year. Loan portfolio growth, composition, average loan size, credit quality considerations, and other environmental factors will continue to determine the level of provision for loan loss expense.
The determination of the allowance for loan and lease losses (“ALLL” or “allowance”) and the related provision for loan losses is a critical accounting estimate that involves management’s judgments about current environmental factors which affect loan losses, such factors including economic conditions, changes in collateral values, net charge-offs, and other factors discussed below in “Additional Management’s Discussion and Analysis.”

Lending Activity and Practices
The Company focuses its lending activities primarily on the following types of loans: 1) first-mortgage, conventional loans secured by residential properties, particularly single-family, 2) commercial lending that concentrates on targeted businesses, and 3) installment lending for consumer purposes (e.g., auto, home equity, etc.). Supplemental information regarding the Company's loan portfolio and credit quality based on regulatory classification is provided in the section captioned “Loans by Regulatory Classification” included in “Part I. Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.” The regulatory classification of loans is based primarily on the type of collateral for the loans. Loan information included in "Part I. Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" is based on the Company's loan segments and classes which is based on the purpose of the loan, unless otherwise noted as a regulatory classification.

1 | As of March 31, 2013, non-performing assets have not been reduced by U.S. government guarantees of $1.4 million.

2 | Amounts represent estimated interest income that would have been recognized on loans accounted for on a non-accrual basis as of the end of each period had such loans performed pursuant to contractual terms.

In the first quarter of 2013, the Company maintained the positive trend of reducing non-performing assets that was established throughout 2012. Non-performing assets at March 31, 2013 were $135 million, a decrease of $8.1 million, or 6 percent, during the current quarter and a decrease of $79.2 million, or 37 percent, from a year ago. The largest category of non-performing assets was the land, lot and other construction category which was $62.3 million, or 46 percent, of the non-performing assets at March 31, 2013. Included in this category was $28.9 million of land development loans and $17.4 million in unimproved land loans at March 31, 2013. The Company has continued to reduce the land, lot and other construction category over the prior two years and during the current quarter, this category of non-performing assets was further reduced by $4.2 million, or 6 percent. The Company's early stage delinquencies (accruing loans 30-89 days past due) of $32.3 million at March 31, 2013 increased $5.2 million, or 19 percent, from the prior quarter and decreased $10.3 million, or 24 percent, from the prior year first quarter early stage delinquencies.

Table of Contents
Most of the Company’s non-performing assets are secured by real estate, and based on the most current information available to management, including updated appraisals or evaluations (new or updated), the Company believes the value of the underlying real estate collateral is adequate to minimize significant charge-offs or loss to the Company. The Company evaluates the level of its non-performing assets, the values of the underlying real estate and other collateral, and related trends in net charge-offs in determining the adequacy of the ALLL. Through pro-active credit administration, the Company works closely with its borrowers to seek favorable resolution to the extent possible, thereby attempting to minimize net charge-offs or losses to the Company. Throughout the past year, the Company has maintained an adequate allowance while working to reduce non-performing assets. The improvement in the credit quality ratios over the past year is a product of this effort.
For non-performing construction loans involving residential structures, the percentage of completion exceeds 95 percent at March 31, 2013. For non-performing construction loans involving commercial structures, the percentage of completion ranges from projects not started to projects completed at March 31, 2013. During the construction loan term, all construction loan collateral properties are inspected at least monthly, or more frequently as needed, until completion. Draws on construction loans are predicated upon the results of the inspection and advanced based upon a percentage of completion basis versus original budget percentages. When construction loans become non-performing and the associated project is not complete, the Company on a case-by-case basis makes the decision to advance additional funds or to initiate collection/foreclosure proceedings. Such decision includes obtaining “as-is” and “at completion” appraisals for consideration of potential increases or decreases in the collateral’s value. The Company also considers the increased costs of monitoring progress to completion, and the related collection/holding period costs should collateral ownership be transferred to the Company. With very limited exception, the Company does not disburse additional funds on non-performing loans. Instead, the Company has proceeded to collection and foreclosure actions in order to reduce the Company’s exposure to loss on such loans.
Construction loans, a regulatory classification, accounted for 40 percent of the Company's non-accrual loans as of March 31, 2013. Land, lot and other construction loans, a regulatory classification, were 94 percent of the non-accrual construction loans. Of the Company’s $36.2 million of non-accrual construction loans at March 31, 2013, 97 percent of such loans had collateral properties securing the loans in Western Montana and Idaho. With locations and operations in the contiguous northern Rocky Mountain states of Idaho and Montana, the geography and economies of each of these geographic areas are predominantly tied to real estate development given the sprawling abundance of timbered valleys and mountainous terrain with significant lakes, streams and watershed areas. Consistent with the general economic downturn, the market for upscale primary, secondary and other housing as well as the associated construction and building industries have stalled after years of significant growth. As the housing market (rental and owner-occupied) and related industries continue to recover from the downturn, the Company continues to reduce its exposure to loss in the land, lot and other construction loan portfolio.
For additional information on accounting policies relating to non-performing assets and impaired loans, see Note 1 to the Consolidated Financial Statements in "Part I. Item 1. Financial Statements."
Impaired Loans
Loans are designated impaired when, based upon current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement and therefore, the Company has serious doubts as to the ability of such borrowers to fulfill the contractual obligation. Impaired loans include non-performing loans (i.e., non-accrual loans and accruing loans ninety days or more past due) and accruing loans under ninety days past due where it is probable payments will not be received according to the loan agreement (e.g., troubled debt restructuring).
Impaired loans were $194 million and $202 million as of March 31, 2013 and December 31, 2012, respectively. The ALLL includes specific valuation allowances of $11.6 million and $15.5 million of impaired loans as of March 31, 2013 and December 31, 2012, respectively. Of the total impaired loans at March 31, 2013, there were 33 significant commercial real estate and other commercial loans that accounted for $94.2 million, or 49 percent, of the impaired loans. The 33 loans were collateralized by 135 percent of the loan value, the majority of which had appraisals or evaluations (new or updated) during the last year, such appraisals reviewed at least quarterly taking into account current market conditions. Of the total impaired loans at March 31, 2013, there were 176 loans aggregating $111 million, or 57 percent, whereby the borrowers had more than one impaired loan. The amount of impaired loans that have had partial charge-offs during the year for which the Company continues to have concern about the collectability of the remaining loan balance was $1.9 million. Of these loans, there were charge-offs of $482 thousand during 2013.

Table of Contents
Restructured Loans
A restructured loan is considered a troubled debt restructuring (“TDR”) if the creditor, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would not otherwise consider. The Company had TDR loans of $127 million and $151 million as of March 31, 2013 and December 31, 2012, respectively. The Company’s TDR loans are considered impaired loans of which $47.0 million and $50.9 million as of March 31, 2013 and December 31, 2012, respectively, are designated as non-accrual.
Each restructured debt is separately negotiated with the borrower and includes terms and conditions that reflect the borrower’s prospective ability to service the debt as modified. The Company discourages the use of the multiple loan strategy when restructuring loans regardless of whether or not the notes are TDR loans. The Company does not have any commercial TDR loans as of March 31, 2013 that have repayment dates extended at or near the original maturity date for which the Company has not classified as impaired. At March 31, 2013, the Company has TDR loans of $40.2 million that are in non-accrual status or that have had partial charge-offs during the year, the borrowers of which continue to have $32.4 million in other loans that are on accrual status.
Other Real Estate Owned
The loan book value prior to the acquisition and transfer of the loan into OREO during 2013 was $7.2 million of which $1.1 million was residential real estate, $4.4 million was commercial, and $1.7 million was consumer loans. The fair value of the loan collateral acquired in foreclosure during 2013 was $6.7 million of which $1.1 million was residential real estate, $3.8 million was commercial, and $1.8 million was consumer loans. The following table sets forth the changes in OREO for the periods indicated:

Allowance for Loan and Lease Losses
Determining the adequacy of the ALLL involves a high degree of judgment and is inevitably imprecise as the risk of loss is difficult to quantify. The ALLL methodology is designed to reasonably estimate the probable loan and lease losses within the Company’s loan portfolio. Accordingly, the ALLL is maintained within a range of estimated losses. The determination of the ALLL, including the provision for loan losses and net charge-offs, is a critical accounting estimate that involves management’s judgments about all known relevant internal and external environmental factors that affect loan losses, including the credit risk inherent in the loan portfolio, economic conditions nationally and in the local markets in which the Company operates, changes in collateral values, delinquencies, non-performing assets and net charge-offs.
Although the Company continues to actively monitor economic trends, soft economic conditions combined with potential declines in the values of real estate that collateralize most of the Company’s loan portfolio may adversely affect the credit risk and potential for loss to the Company.
The ALLL evaluation is well documented and approved by the Company’s Board of Directors. In addition, the policy and procedures for determining the balance of the ALLL are reviewed annually by the Company’s Board of Directors, the internal audit department, independent credit reviewers and state and federal bank regulatory agencies.
At the end of each quarter, the Company analyzes its loan portfolio and maintains an ALLL at a level that is appropriate and determined in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The allowance consists of a specific valuation allowance component and a general valuation allowance component. The specific valuation allowance component relates to loans that are determined to be impaired. A specific valuation allowance is established when the fair value of a collateral-dependent loan or the present value of the loan’s expected future cash flows (discounted at the loan’s effective interest rate) is lower than the carrying value of the impaired loan. The general valuation allowance component relates to probable credit losses inherent in the balance of the loan portfolio based on prior loss experience, adjusted for changes in trends and conditions of qualitative or environmental factors.

The Bank divisions’ credit administration reviews their respective loan portfolios to determine which loans are impaired and estimates the specific valuation allowance. The impaired loans and related specific valuation allowance are then provided to the Company’s credit administration for further review and approval. The Company’s credit administration also determines the estimated general valuation and reviews and approves the overall ALLL for the Company. The credit administration of the Company exercises significant judgment when evaluating the effect of applicable qualitative or environmental factors on the Company’s historical loss experience for loans not identified as impaired. Quantification of the impact upon the Company’s ALLL is inherently subjective as data for any factor may not be directly applicable, consistently relevant, or reasonably available for management to determine the precise impact of a factor on the collectability of the Company’s unimpaired loan portfolio as of each evaluation date. The Company’s credit administration documents its conclusions and rationale for changes that occur in each applicable factor’s weight (i.e., measurement) and ensures that such changes are directionally consistent based on the underlying current trends and conditions for the factor. To have directional consistency, the provision for loan losses and credit quality should generally move in the same direction.
The Company’s model of eleven bank divisions with separate management teams provides substantial local oversight to the lending and credit management function. The Company’s business model affords multiple reviews of larger loans before credit is extended, a significant benefit in mitigating and managing the Company’s credit risk. The geographic dispersion of the market areas in which the Company operates further mitigates the risk of credit loss. While this process is intended to limit credit exposure, there can be no assurance that further problem credits will not arise and additional loan losses incurred, particularly in periods of rapid economic downturns.
The primary responsibility for credit risk assessment and identification of problem loans rests with the loan officer of the account. This continuous process of identifying impaired loans is necessary to support management’s evaluation of the ALLL adequacy. An independent loan review function verifying credit risk ratings evaluates the loan officer and management’s evaluation of the loan portfolio credit quality. The loan review function also assesses the evaluation process and provides an independent analysis of the adequacy of the ALLL.
No assurance can be given that the Company will not, in any particular period, sustain losses that are significant relative to the ALLL amount, or that subsequent evaluations of the loan portfolio applying management’s judgment about then current factors, including economic and regulatory developments, will not require significant changes in the ALLL. Under such circumstances, this could result in enhanced provisions for loan losses.

Net charge-offs as a percentage of total loans | 0.06 | % |  | 0.83 | % |  | 0.28 | %

The Company’s allowance of $131 million is considered adequate to absorb losses from any class of its loan portfolio. For the periods ended March 31, 2013 and 2012, the Company believes the allowance is commensurate with the risk in the Company’s loan portfolio and is directionally consistent with the change in the quality of the Company’s loan portfolio.
At March 31, 2013, the allowance was $131 million, a decrease of $19 thousand from the prior quarter and a decrease of $5.8 million from a year ago. The allowance was 3.84 percent of total loans outstanding at March 31, 2013, compared to 3.85 percent at December 31, 2012 and 3.98 percent at March 31, 2012. The allowance was 143 percent of non-performing loans at March 31, 2013, an increase from 133 percent at December 31, 2012 and an increase from 97 percent at March 31, 2012.
When applied to the Company’s historical loss experience, the qualitative or environmental factors result in the provision for loan losses being recorded in the period in which the loss has probably occurred. When the loss is confirmed at a later date, a charge-off is recorded. During 2013, loan charge-offs, net of recoveries, exceeded the provision for loan losses by $19 thousand. During the same period in 2012, loan charge-offs, net of recoveries, exceeded the provision for loan losses by $930 thousand.
The Company provides commercial services to individuals, small to medium size businesses, community organizations and public entities from 108 locations, including 100 branches, across Montana, Idaho, Wyoming, Colorado, Utah, and Washington. The Rocky Mountain states in which the Company operates has diverse economies and markets that are tied to commodities (crops, livestock, minerals, oil and natural gas), tourism, real estate and land development and an assortment of industries, both manufacturing and service-related. Thus, the changes in the global, national, and local economies are not uniform across the Company’s geographic locations.

Although there continues to be heightened uncertainty in the economic environment, there was notable improvements during the last year compared to the past several years. There was steady growth in the housing permits, housing starts, and completions for new privately owned units during the last year in Montana, Idaho, Colorado and Utah in relation to the US national statistics. There was improvement in single family residential real estate construction and sales for all of the Company's market areas. Single family residential collateral values in Idaho, Wyoming and Montana stabilized (with some improvement in isolated markets in which the Company operates) compared to the prior year and prior 5 year historical trends. There was a steady decline in the number of foreclosures initiated in 2012 for Montana, Idaho, and Wyoming. The unemployment rates for the states in which the Company conducts operations were generally lower compared to the national unemployment rate. National unemployment rates increased steadily from 5.0 in the first part of 2008 to a range of 7.8 to 10.0 during 2009 through 2012 and has recently declined to 7.6 in March of 2013. Agricultural price declines in livestock and grain in 2009 have recovered significantly and remain strong. While prices for oil have held strong, prices for natural gas continue to remain weak (due to excess supply) especially when compared to the exceptionally high price levels of natural gas during 2008. The tourism industry and related lodging continues to be a source of strength for the locations where the Company’s market areas have national parks and similar recreational areas in the market areas served.
In evaluating the need for a specific or general valuation allowance for impaired and unimpaired loans, respectively, within the Company’s construction loan portfolio, (i.e., regulatory classification), including residential construction and land, lot and other construction loans, the credit risk related to such loans was considered in the ongoing monitoring of such loans, including assessments based on current information, including appraisals or evaluations (new or updated) of the underlying collateral, expected cash flows and the timing thereof, as well as the estimated cost to sell when such costs are expected to reduce the cash flows available to repay or otherwise satisfy the construction loan. Construction loans are 12 percent of the Company’s total loan portfolio and account for 40 percent of the Company’s non-accrual loans at March 31, 2013. Collateral securing construction loans includes residential buildings (e.g., single/multi-family and condominiums), commercial buildings, and associated land (multi-acre parcels and individual lots, with and without shorelines).
The Company’s allowance consisted of the following components as of the dates indicated:

(Dollars in thousands) | March 31, 2013 |  | December 31, 2012 |  | March 31, 2012
Specific valuation allowance | $ | 11,601 |  |  | 15,534 |  |  | 20,507 |
General valuation allowance | 119,234 |  |  | 115,320 |  |  | 116,079 |
Total ALLL | $ | 130,835 |  |  | 130,854 |  |  | 136,586 |

During 2013, the ALLL decreased by $19 thousand, the net result of a $3.9 million decrease in the specific valuation allowance and a $3.9 million increase in the general valuation allowance. The decrease in the specific valuation allowance since the prior year end was primarily due to the decrease in loans with a specific valuation allowance of $7.9 million. The increase in the general valuation allowance was the result of a $14.3 million increase in loans collectively evaluated for impairment. Further supporting the small decrease in the ALLL were the following trends:

• | Non-accrual construction loans (i.e., residential construction and land, lot and other construction, each a regulatory classification) were $36.2 million, or 40 percent, of the $90.9 million of non-accrual loans at March 31, 2013, a decrease of $3.0 million from the prior year end and decrease of $26.4 million from March 31, 2012. Non-accrual construction loans accounted for 40 percent of the $96.9 million of non-accrual loans at year end 2012 and 48 percent of the $131 million of non-accrual loans at March 31, 2012.

• | Non-performing loans as a percent of total loans decreased to 2.69 percent at March 31, 2013 as compared to 2.90 percent and 4.09 percent at year end 2012 and March 31, 2012, respectively.

• | Impaired loans as a percent of total loans decreased to 5.70 percent at March 31, 2013 as compared to 5.94 percent and 7.90 percent at year end 2011 and March 31, 2012, respectively.

• | Charge-offs, net of recoveries, in 2013 were $2.1 million, a $7.4 million decrease from the same period in 2012.

The Company’s investment portfolio is primarily comprised of residential mortgage-backed securities and state and local government securities which are largely exempt from federal income tax. The Company uses the maximum federal statutory rate of 35 percent in calculating its tax-equivalent yield. The residential mortgage-backed securities are typically short weighted-average life U.S. government agency CMOs and provide the Company with on-going liquidity as scheduled and pre-paid principal payments are made on the securities. It has generally been the Company’s policy to maintain a liquid portfolio above policy limits.
For additional investment activity information, see Note 2 to the Consolidated Financial Statements in “Part I. Item 1. Financial Statements.”
Other-Than-Temporary Impairment on Securities Analysis
Non-marketable equity securities owned at March 31, 2013 primarily consisted of stock issued by the FHLB of Seattle, such shares measured at cost in recognition of the transferability restrictions imposed by the issuers. Other non-marketable equity securities include Federal Agriculture Mortgage Corporation and Bankers' Bank of the West Bancorporation, Inc.
With respect to FHLB stock, the Company evaluates such stock for other-than-temporary impairment. Such evaluation takes into consideration 1) FHLB deficiency, if any, in meeting applicable regulatory capital targets, including risk-based capital requirements, 2) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the time period for any such decline, 3) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, 4) the impact of legislative and regulatory changes on the FHLB, and 5) the liquidity position of the FHLB.
Based on the Company's analysis of its impaired non-marketable equity securities as of March 31, 2013, the Company determined that none of such securities had other-than-temporary impairment.
In evaluating debt securities for other-than-temporary impairment losses, management assesses whether the Company intends to sell the security or if it is more-likely-than-not that the Company will be required to sell the debt security. In so doing, management considers contractual constraints, liquidity, capital, asset / liability management and securities portfolio objectives.
The Company believes that macroeconomic conditions occurring in the first quarter of 2013 and throughout 2012 and 2011 have unfavorably impacted the fair value of certain debt securities in its investment portfolio. In August 2011, Standard and Poor's downgraded the United States long-term debt rating from its AAA rating to AA+ with a negative outlook. Both Moody's and Fitch have continued to maintain their long-term debt ratings of the United States as Aaa and AAA, respectively, each with a negative outlook. Standard and Poor's, Moody's and Fitch have similar credit ratings and outlooks with respect to certain long-term debt instruments issued by Fannie Mae, Freddie Mac and other U.S. government agencies linked to long-term United States debt. For debt securities with limited or inactive markets, the impact of these macroeconomic conditions upon fair value estimates includes higher risk-adjusted discount rates and downgrades in credit ratings provided by nationally recognized credit rating agencies, (e.g., Moody's, Standard and Poor's, and Fitch).

With respect to the duration of the impaired debt securities, the Company identified 22 securities which have been continuously impaired for the twelve months ending March 31, 2013. The valuation history of such securities in the prior year(s) was also reviewed to determine the number of months in prior year(s) in which the identified securities was in an unrealized loss position.
The following table provides details of the 22 securities which have been continuously impaired for the twelve months ended March 31, 2013, including the most notable loss for any one bond in each category.

(Dollars in thousands) | Number of Debt Securities |  | Unrealized Loss for 12 Months Or More |  | Most Notable Loss
State and local governments | 16 |  |  | $ | (289 | ) |  | (79 | )
Residential mortgage-backed securities | 6 |  |  | (212 | ) |  | (163 | )
Total | 22 |  |  | $ | (501 | ) |  |

Of the 6 residential mortgage-backed securities, 3 have underlying collateral consisting of U.S. government guaranteed mortgages (e.g. GNMA) and U.S. government sponsored enterprise (e.g. FHLMC) guaranteed mortgages. Each of the 3 remaining residential mortgage-backed securities have underlying non-guaranteed private label whole loan collateral of 30-year fixed rate residential mortgages considered to be “Prime”. The Company engages a third-party to perform detailed analysis for other-than-temporary impairment of such securities. Such analysis takes into consideration original and current data for the tranche and CMO structure, the non-guaranteed classification of each CMO tranche, current and deal inception credit ratings, credit support (protection) afforded the tranche through the subordination of other tranches in the CMO structure, the nature of the collateral (e.g., Prime or Alt-A) underlying each CMO tranche, and realized cash flows since purchase.
Based on the Company's analysis of its impaired debt securities as of March 31, 2013, the Company determined that none of such securities had other-than-temporary impairment.
Sources of Funds
The Company’s deposits have traditionally been the principal source of funds for use in lending and other business purposes. The Company has a number of different deposit programs designed to attract both short-term and long-term deposits from the general public by providing a wide selection of accounts and rates. These programs include non-interest bearing demand accounts, interest bearing checking, regular statement savings, money market deposit accounts, and fixed rate certificates of deposit with maturities ranging from three months to five years, negotiated-rate jumbo certificates, and individual retirement accounts. In addition, the Company obtains wholesale deposits through various programs and are classified as NOW accounts, money market deposit accounts and certificate accounts.
The Company also obtains funds from repayment of loans and investment securities, securities sold under agreements to repurchase ("repurchase agreements"), advances from the FHLB, other borrowings, and sale of loans and investment securities. Loan repayments are a relatively stable source of funds, while interest bearing deposit inflows and outflows are significantly influenced by general interest rate levels and market conditions. Borrowings and advances may be used on a short-term basis to compensate for reductions in normal sources of funds such as deposit inflows at less than projected levels. Borrowings also may be used on a long-term basis to support expanded activities and to match maturities of longer-term assets.

Table of Contents
Short-term borrowings
A critical component of the Company’s liquidity and capital resources is access to short-term borrowings to fund its operations. Short-term borrowings are accompanied by increased risks managed by the Asset Liability Committee (“ALCO”) such as rate increases or unfavorable change in terms which would make it more costly to obtain future short-term borrowings. The Company’s short-term borrowing sources include FHLB advances, federal funds purchased and retail and wholesale repurchase agreements. The Company also has access to the short-term discount window borrowing programs (i.e., primary credit) of the Federal Reserve Bank. FHLB advances and certain other short-term borrowings may be extended as long-term borrowings to decrease certain risks such as liquidity or interest rate risk; however, the reduction in risks are weighed against the increased cost of funds.
The following table provides information relating to short-term borrowings which consists of borrowings that mature within one year at period end:

Weighted average interest rate | 0.28 | % |  | 0.50 | %

Contractual Obligations and Off-Balance Sheet Arrangements
The Company has outstanding debt maturities, the largest aggregate amount of which were FHLB advances. In the normal course of business, there may be various outstanding commitments to obtain funding, such as brokered deposits, and to extend credit, such as letters of credit and un-advanced loan commitments, which are not reflected in the accompanying condensed consolidated financial statements. The Company does not anticipate any material losses as a result of these transactions.

Liquidity Risk
Liquidity risk is the possibility that the Company will not be able to fund present and future obligations as they come due because of an inability to liquidate assets or obtain adequate funding at a reasonable cost. The objective of liquidity management is to maintain cash flows adequate to meet current and future needs for credit demand, deposit withdrawals, maturing liabilities and corporate operating expenses. Effective liquidity management entails three elements:

1. | Assessing on an ongoing basis, the current and expected future needs for funds, and ensuring that sufficient funds or access to funds exist to meet those needs at the appropriate time.

2. | Providing for an adequate cushion of liquidity to meet unanticipated cash flow needs that may arise from potential adverse circumstances ranging from high probability/low severity events to low probability/high severity.

3. | Balancing the benefits between providing for adequate liquidity to mitigate potential adverse events and the cost of that liquidity.

The following table identifies certain liquidity sources and capacity available to the Company at March 31, 2013:

(Dollars in thousands) | March 31, 2013

The Company has a wide range of versatility in managing the liquidity and asset/liability mix. The Company’s ALCO committee meets regularly to assess liquidity risk, among other matters. The Company monitors liquidity and contingency funding alternatives through management reports of liquid assets (e.g., investment securities), both unencumbered and pledged, as well as borrowing capacity, both secured and unsecured.

Capital Resources
Maintaining capital strength continues to be a long-term objective. Abundant capital is necessary to sustain growth, provide protection against unanticipated declines in asset values, and to safeguard the funds of depositors. Capital is also a source of funds for loan demand and enables the Company to effectively manage its assets and liabilities. Taking these considerations into account, the Company may, as it has done in the past, decide to utilize a portion of its strong capital position to repurchase shares of its outstanding common stock, from time to time, depending on market price and other relevant considerations.
The Federal Reserve Board has adopted capital adequacy guidelines that are used to assess the adequacy of capital in supervising a bank holding company. The Company and the Bank were considered well capitalized by their respective regulators as of March 31, 2013 and 2012. There are no conditions or events after March 31, 2013 that management believes have changed the Company’s or the Bank’s risk-based capital category.
The following table illustrates the Federal Reserve Board’s capital adequacy guidelines and the Company’s compliance with those guidelines as of March 31, 2013.

Federal and State Income Taxes
The Company files a consolidated federal income tax return, using the accrual method of accounting. All required tax returns have been timely filed. Financial institutions are subject to the provisions of the Internal Revenue Code of 1986, as amended, in the same general manner as other corporations.

Wyoming and Washington do not impose a corporate-level income tax.
The Company has equity investments in Certified Development Entities which have received allocations of New Markets Tax Credits (“NMTC”). Administered by the Community Development Financial Institutions Fund of the U.S. Department of the Treasury, the NMTC program is aimed at stimulating economic and community development and job creation in low-income communities. The federal income tax credits received are claimed over a seven-year credit allowance period. The Company also has equity investments in Low-Income Housing Tax Credits which are indirect federal subsidies used to finance the development of affordable rental housing for low-income households. The federal income tax credits are claimed over a ten-year credit allowance period. The Company has investments in Qualified Zone Academy and Qualified School Construction bonds whereby the Company receives quarterly federal income tax credits in lieu of taxable interest income until the bonds mature. The federal income tax credits on these bonds are subject to federal and state income tax.
Following is a list of expected federal income tax credits to be received in the years indicated.

Income tax expense for the three months ended March 31, 2013 and 2012 was $7.1 million and $4.6 million, respectively. The Company’s effective tax rate for the three months ended March 31, 2013 and 2012 was 25.6 percent and 22.1 percent, respectively. The primary reason for the low effective rates are the amount of tax-exempt investment income and federal tax credits. The tax-exempt income was $9.8 million and $9.7 million for the three months ended March 31, 2013 and 2012, respectively. The federal tax credit benefits were $550 thousand and $432 thousand for the three months ended March 31, 2013 and 2012, respectively. The Company continues to hold its investments in select municipal securities and variable interest entities whereby the Company receives federal tax credits.

Rate/Volume Analysis
Net interest income can be evaluated from the perspective of relative dollars of change in each period. Interest income and interest expense, which are the components of net interest income, are shown in the following table on the basis of the amount of any increases (or decreases) attributable to changes in the dollar levels of the Company’s interest earning assets and interest bearing liabilities (“Volume”) and the yields earned and rates paid on such assets and liabilities (“Rate”). The change in interest income and interest expense attributable to changes in both volume and rates has been allocated proportionately to the change due to volume and the change due to rate.

| Three Months ended March 31,
| 2013 vs. 2012
| Increase (Decrease) Due to:
(Dollars in thousands) | Volume |  | Rate |  | Net
Interest income |  |  |  |  |
Residential real estate loans | $ | 441 |  |  | (965 | ) |  | (524 | )
Commercial loans | (260 | ) |  | (2,149 | ) |  | (2,409 | )
Consumer and other loans | (744 | ) |  | (562 | ) |  | (1,306 | )
Investment securities (tax-equivalent) | 2,998 |  |  | (8,633 | ) |  | (5,635 | )
Total interest income | 2,435 |  |  | (12,309 | ) |  | (9,874 | )

Total interest expense | (251 | ) |  | (1,889 | ) |  | (2,140 | )
Net interest income (tax equivalent) | $ | 2,686 |  |  | (10,420 | ) |  | (7,734 | )

Net interest income (tax-equivalent) decreased $7.7 million for the three months ended March 31, 2013 compared to the same period in 2012. The decrease in interest income was driven primarily by the premium amortization (net of discount accretion) on investment securities and reduced interest rates on the loan portfolio. Although, the Company was able to lower interest expense by reducing deposit and borrowing interest rates, it was not enough to offset the reduction in interest income.
Effect of inflation and changing prices
GAAP often requires the measurement of financial position and operating results in terms of historical dollars, without consideration for change in relative purchasing power over time due to inflation. Virtually all assets of the Company are monetary in nature; therefore, interest rates generally have a more significant impact on a company’s performance than does the effect of inflation.
