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 individuals and businesses in Montana, Idaho, Utah, Washington, Wyoming, Colorado and Arizona through 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 and mortgage origination 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 September 30, 2017 , the results of operations and comprehensive income for the three and nine month periods ended September 30, 2017 and 2016 , and changes in stockholders’ equity and cash flows for the nine month periods ended September 30, 2017 and 2016 . The condensed consolidated statement of financial condition of the Company as of December 31, 2016 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, 2016 . Operating results for the nine months ended September 30, 2017 are not necessarily indicative of the results anticipated for the year ending December 31, 2017 .

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: 1) the determination of the allowance for loan and lease losses (“ALLL” or “allowance”); 2) the valuation of investment securities; 3) the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans; and 4) the evaluation of goodwill impairment. For the determination of the ALLL and real estate valuation estimates, management obtains independent appraisals (new or updated) for significant items. Estimates relating to investment valuations are obtained from independent third parties. Estimates relating to the evaluation of goodwill for impairment are determined based on internal calculations using significant independent party inputs.

Principles of Consolidation

The consolidated financial statements of the Company include the parent holding company and the Bank. The Bank consists of fourteen bank divisions, a treasury division, an information technology division and a centralized mortgage division. The treasury division includes the Bank’s investment portfolio and wholesale borrowings, the information technology division includes the Bank’s internal data processing, and the centralized mortgage division includes mortgage loan servicing and secondary market sales. The Bank divisions operate under separate names, management teams and advisory 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 Bank has subsidiary interests in variable interest entities (“VIE”) for which the Bank has both the power to direct the VIE’s significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could potentially be significant to the VIE. These subsidiary interests are included in the Company’s consolidated financial statements. The parent holding company also owns non-bank subsidiaries that have issued trust preferred securities as Tier 1 capital instruments. The trust subsidiaries are not included in the Company’s consolidated financial statements. The Company's investments in the trust subsidiaries are included in non-marketable equity securities on the Company's statement of financial condition.

In April 2017, the Company completed its acquisition of TFB Bancorp, Inc. and its wholly-owned subsidiary, The Foothills Bank, a community bank based in Yuma, Arizona (collectively, “Foothills”). In August 2016, the Company completed its acquisition of Treasure State Bank, a community bank based in Missoula, Montana. The transactions were accounted for using the acquisition method, and their results of operations have been included in the Company’s consolidated financial statements as of the acquisition dates.

Pending Acquisition

In June 2017, the Company announced the signing of a definitive agreement to acquire Columbine Capital Corp., and its wholly-owned subsidiary, Collegiate Peaks Bank, a community bank based in Buena Vista, Colorado (collectively, “Collegiate”). Collegiate provides banking services to businesses and individuals in the Mountain and Front Range communities of Colorado, with banking offices located in Aurora, Buena Vista, Denver and Salida. As of September 30, 2017, Collegiate had total assets of $536,387,000 , gross loans of $331,486,000 and total deposits of $460,380,000 . The acquisition is subject to required regulatory approvals and other customary conditions of closing and is expected to be completed during the first quarter of 2018. Upon closing of the transaction, Collegiate will be merged into Glacier Bank and will operate as a separate bank division under its existing name and management team.

Loans Receivable

Loans that are intended to be held-to-maturity are reported at the unpaid principal balance less net charge-offs and adjusted for deferred fees and costs on originated loans and unamortized premiums or discounts on acquired loans. Fees and costs on originated loans and premiums or discounts on acquired loans are deferred and subsequently amortized or accreted as a yield adjustment over the expected life of the loan utilizing the interest method. The objective of the interest method is to calculate periodic interest income at a constant effective yield. When a loan is paid off prior to maturity, the remaining fees and costs on originated loans and premiums or discounts on acquired loans are immediately recognized into interest income.

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).

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 on non-accrual loans 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 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., troubled debt restructuring). 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 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 periodically enters into restructure agreements with borrowers whereby the loans were previously identified as TDRs. When such circumstances occur, the Company carefully evaluates the facts of the subsequent restructure to determine the appropriate accounting and under certain circumstances it may be acceptable not to account for the subsequently restructured loan as a TDR. When assessing whether a concession has been granted by the Company, any prior forgiveness on a cumulative basis is considered a continuing concession. 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 has 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.

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 are TDRs, 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.

For additional information relating to loans, see Note 3.

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 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.

Risk characteristics considered in the ALLL analysis applicable to each loan class within the Company's loan portfolio are as follows:

Residential Real Estate. Residential real estate loans are secured by owner-occupied 1-4 family residences. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans is impacted by economic conditions within the Company’s market areas that affect the value of the property securing the loans and affect the borrowers' personal incomes. Mitigating risk factors for this loan class include a large number of borrowers, geographic dispersion of market areas and the loans are originated for relatively smaller amounts.

Commercial Real Estate . Commercial real estate loans typically involve larger principal amounts, and repayment of these loans is generally dependent on the successful operation of the property securing the loan and/or the business conducted on the property securing the loan. Credit risk in these loans is impacted by the creditworthiness of a borrower, valuation of the property securing the loan and conditions within the local economies in the Company’s diverse, geographic market areas.

Commercial . Commercial loans consist of loans to commercial customers for use in financing working capital needs, equipment purchases and business expansions. The loans in this category are repaid primarily from the cash flow of a borrower’s principal business operation. Credit risk in these loans is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations across the Company’s diverse, geographic market areas.

Home Equity . Home equity loans consist of junior lien mortgages and first and junior lien lines of credit (revolving open-end and amortizing closed-end) secured by owner-occupied 1-4 family residences. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans is impacted by economic conditions within the Company’s market areas that affect the value of the residential property securing the loans and affect the borrowers' personal incomes. Mitigating risk factors for this loan class are a large number of borrowers, geographic dispersion of market areas and the loans are originated for terms that range from 10 to 15 years .

Other Consumer . The other consumer loan portfolio consists of various short-term loans such as automobile loans and loans for other personal purposes. Repayment of these loans is primarily dependent on the personal income of the borrowers. Credit risk is driven by consumer economic factors (such as unemployment and general economic conditions in the Company’s diverse, geographic market area) and the creditworthiness of a borrower.

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 evaluated for each class within the loan portfolio 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 global, 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 and 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.

At acquisition date, the assets and liabilities of acquired banks are recorded at their estimated fair values which results in no ALLL carried over from acquired banks. Subsequent to acquisition, an allowance will be recorded on the acquired loan portfolios for further credit deterioration, if any.

Reclassifications

Certain reclassifications have been made to the 2016 financial statements to conform to the 2017 presentation.

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. The following paragraphs provide descriptions of recently adopted or newly issued but not yet effective accounting standards that could have a material effect on the Company’s financial position or results of operations.

In August 2017, FASB amended FASB ASC Topic 815, Derivatives and Hedging . The objective of the amendments were to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, the amendments made targeted improvements to simplify the application of the hedge accounting guidance. The amendments are effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The Company is currently evaluating the full impact of the amendments on its existing interest rate swaps and whether it will early adopt. The Company does not expect there to be an impact to the Company’s financial position and results of operations, although, there may be additional financial statement disclosures. The accounting policies and procedures will be modified after the Company has fully evaluated the standard, although significant changes are not expected.

In March 2017, FASB amended FASB ASC Subtopic 310-20, Receivables-Nonrefundable Fees and Other Costs. The amendments in the Update shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date instead of the maturity date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments are effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted and if adopted in an interim period, any adjustments should be reflected as of the beginning of the year that includes the interim period. The entity should apply the amendments on a modified retrospective basis through a cumulative-effective adjustment directly to retained earnings as of the beginning of the period of adoption. The Company has premiums on debt securities that are currently being amortized to the maturity date, primarily in the state and local governments category. The Company is currently evaluating the amount of the premium associated with debt securities that will be impacted by the amendments, the impact the amendments will have to the Company’s financial position and results of operations, and whether it will early adopt. The accounting policies and procedures will be modified after the Company has fully evaluated the standard, although significant changes are not expected.

In January 2017, FASB amended FASB ASC Topic 350, Simplifying the Test for Goodwill. The amendments in the Update simplify the measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Instead, under these amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss should not exceed the total amount of goodwill allocated to that reporting unit. The amendments are effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company has goodwill from prior business combinations and performs an annual impairment test or more frequently if changes or circumstances occur that would more-likely-than-not reduce the fair value of the reporting unit below its carrying value. During the third quarter of 2017, the Company performed its impairment assessment and determined the fair value of the aggregated reporting units exceed the carrying value, such that the Company’s goodwill was not considered impaired. Although the Company cannot anticipate future goodwill impairment assessments, based on the most recent assessment, it is unlikely that an impairment amount would need to be calculated and, therefore, the Company does not anticipate a material impact from these amendments to the Company’s financial position and results of operations. The current accounting policies and processes are not anticipated to change, except for the elimination of the Step 2 analysis. For additional information regarding goodwill impairment testing, see Note 4.

In June 2016, FASB amended FASB ASC Topic 326, Financial Instruments - Credit Losses. The amendments in this Update replace the incurred loss model with a methodology that reflects expected credit losses over the life of the loan and requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. The amendments are effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2019. The Company is currently evaluating the impact of these amendments to the Company’s financial position and results of operations and currently does not know or cannot reasonably quantify the impact of the adoption of the amendments as a result of the complexity and extensive changes from the amendments. The ALLL is a material estimate of the Company and given the change from an incurred loss model to a methodology that considers the credit loss over the life of the loan, there is the potential for an increase in the ALLL at adoption date. The Company is anticipating a significant change in the processes and procedures to calculate the ALLL, including changes in assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. The Company will also develop new procedures for determining an allowance for credit losses relating to held-to-maturity investment securities. In addition, the current accounting policy and procedures for other-than-temporary impairment on available-for-sale investment securities will be replaced with an allowance approach. The Company has formed a project team and is actively reviewing the standard for developing and implementing processes and procedures during the next two years to ensure it is fully compliant with the amendments at adoption date. For additional information on the allowance for loan losses, see Note 3.

In March 2016, FASB amended FASB ASC Topic 718, Compensation - Stock Compensation. The amendments in this Update address certain aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification of awards on the statement of cash flows. The amendments were effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2016 and the Company adopted the amendments as of January 1, 2017. The amendments require entities to recognize all income tax effects related to share-based payment awards in the statement of operations when the awards vest or are settled. Previously, income tax benefits at the settlement of awards were reported as increases (or decreases) to additional paid-in capital to the extent that those benefits were greater than (or less than) the income tax benefits recognized in earnings during the awards’ vesting periods. Such amounts are to be classified as an operating activity in the statement of cash flows instead of the prior accounting treatment, which required it to be classified as both an operating and a financing activity. The Company has elected to apply this classification change on a retrospective basis. Also in connection with the adoption of the Update, the Company has elected to change its accounting policy to recognize forfeitures as they occur. The requirement to report income tax effects in earnings has been applied to the settlement of awards on a prospective basis and the impact of applying the guidance reduced reported income tax expense for the nine month period ended September 30, 2017 by $555,000 , or approximately $0.01 per diluted common share. The implementation of the remaining provisions of the Update did not have a significant impact on the Company’s consolidated financial statements.

In February 2016, FASB amended FASB ASC Topic 842, Leases. The amendments in this Update address several aspects of lease accounting with the significant change being the recognition of lease assets and lease liabilities for leases previously classified as operating leases. The amendments are effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2018, and early adoption is permitted. The Company has several lease agreements for which the amendments will require the Company to recognize a lease liability to make lease payments and a right-of-use asset which will represent its right to use the underlying asset for the lease term. The Company is currently reviewing the amendments to ensure it is fully compliant by the adoption date and doesn’t expect to early adopt. As permitted by the amendments, the Company is anticipating electing an accounting policy to not recognize lease assets and lease liabilities for leases with a term of twelve months or less. The impact is not expected to have a material effect on the Company’s financial position or results of operations since the Company does not have a material amount of lease agreements. The Company is currently in the process of fully evaluating the amendments and will subsequently implement new processes which are not expected to significantly change since the Company already has processes for certain lease agreements that recognize the lease assets and lease liabilities. In addition, the Company will change its current accounting policies to comply with the amendments with such changes as mentioned above.

In January 2016, FASB amended FASB ASC Topic 825, Financial Instruments. The amendments in this Update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments are effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2017. Early adoption is only permitted under certain circumstances outlined in the amendments. A reporting entity should apply the amendments by means of a cumulative-effect adjustment to the Company’s statement of financial condition as of the beginning of the reporting year of adoption. The amendments will impact the Company in a few areas including requiring equity investments (with certain exclusions) to be measured at fair value with the changes recognized in net income, requirement to utilize an exit price when measuring the fair value of financial instruments, additional disclosures related to other comprehensive income, evaluation of a valuation allowance on a deferred tax asset related to available-for-sale investment securities in combination with the entity’s other deferred tax assets, and other disclosure changes. The Company is currently evaluating the impact of these amendments, but does not expect them to have a material material effect on the Company’s financial position or results of operations since it does not have a material amount of equity securities or a valuation allowance. However, the amendments will have an impact on certain items that are disclosed at fair value that are not currently utilizing the exit price notion when measuring fair value. As of September 30, 2017 , the Company cannot quantify the change in the fair value of such disclosures since the Company is currently evaluating the full impact of the Update. The Company is actively developing appropriate procedures and processes to comply with the disclosure requirements of such amendments. The current accounting policies and procedures will be modified after the Company has fully evaluated the standard to comply with the accounting changes mentioned above.

In May 2014, FASB amended FASB ASC Topic 606, Revenue from Contracts with Customers. The amendments clarify the principles for recognizing revenue and develop a common revenue standard among industries. The new guidance establishes the following core principle: recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for goods or services. Five steps are provided for a company or organization to follow to achieve such core principle. The new guidance also includes a cohesive set of disclosure requirements that will provide users of financial statements with comprehensive information about the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The entity should apply the amendments using one of two retrospective methods described in the amendment. Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers (Topic 606) delayed the effective date for public entities to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Several subsequent amendments have been issued that provide clarifying guidance and are effective with the adoption of the original Update. The Company continues to evaluate the standard and the impact of these amendments, although it doesn’t expect the amendments to have a significant impact to the Company’s financial position, results of operation, or disclosures. The amendments could potentially impact the accounting procedures and processes over the recognition of certain revenue sources, including, but not limited to, non-interest income. The Company is actively documenting its evaluation of the standard and developing processes and procedures to ensure it is fully compliant with these amendments at the date of adoption.

Based on an analysis of its investment securities with unrealized losses as of September 30, 2017 and December 31, 2016 , the Company determined that none of such securities had other-than-temporary impairment and the unrealized losses were primarily the result of interest rate changes and market spreads subsequent to acquisition. The fair value of the investment securities is expected to recover as payments are received and the securities approach maturity. At September 30, 2017 , management determined that it did not intend to sell investment securities with unrealized losses, and there was no expected requirement to sell any of its investment securities with unrealized losses before recovery of their amortized cost.

At September 30, 2017 and December 31, 2016 , the Company had $986,000 and $2,699,000 , respectively, of OREO secured by residential real estate properties.

Note 4. Goodwill

The following schedule discloses the changes in the carrying value of goodwill:



	Three Months ended			Nine Months ended
(Dollars in thousands)	September 30, 2017		September 30, 2016	September 30, 2017	September 30, 2016
Net carrying value at beginning of period	$	177,811	140,638	147,053	140,638
Acquisitions and adjustments	—		6,415	30,758	6,415
Net carrying value at end of period	$	177,811	147,053	177,811	147,053

The gross carrying value of goodwill and the accumulated impairment charge consists of the following:



(Dollars in thousands)	September 30, 2017			December 31, 2016
Gross carrying value	$	217,970		187,212
Accumulated impairment charge ¹	(40,159		)	(40,159	)
Net carrying value	$	177,811		147,053

__________

¹ A goodwill impairment charge was recognized in 2011 and was due to high levels of volatility and dislocation in bank stock prices nationwide.

The Company performed its annual goodwill impairment test during the third quarter of 2017 and determined the fair value of the aggregated reporting units exceeded the carrying value, such that the Company’s goodwill was not considered impaired. Changes 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.

For additional information on goodwill related to acquisitions, see Note 12.

Note 5. Variable Interest Entities

A VIE is a partnership, limited liability company, trust or other legal entity that meets one of the following criteria: 1) the entity’s equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support from other parties; 2) the holders of the equity investment at risk, as a group, lack the characteristics of a controlling financial interest; and 3) the voting rights of some holders of the equity investment at risk are disproportionate to their obligation to absorb losses or receive returns, and substantially all of the activities are conducted on behalf of the holder of equity investment at risk with disproportionately few voting rights. A VIE must be consolidated by the Company if it is deemed to be the primary beneficiary, which is the party involved with the VIE that has both: 1) the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance; and 2) the obligation to absorb the losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE.

The Company’s VIEs are regularly monitored to determine if any reconsideration events have occurred that could cause the primary beneficiary status to change. A previously unconsolidated VIE is consolidated when the Company becomes the primary beneficiary. A previously consolidated VIE is deconsolidated when the Company ceases to be the primary beneficiary or the entity is no longer a VIE.

Consolidated Variable Interest Entities

The Company has equity investments in Certified Development Entities (“CDE”) which have received allocations of New Markets Tax Credits (“NMTC”). The NMTC program provides federal tax incentives to investors to make investments in distressed communities and promotes economic improvements through the development of successful businesses in these communities. The NMTC is available to investors over a seven -year period and is subject to recapture if certain events occur during such period. The maximum exposure to loss in the CDEs is the amount of equity invested and credit extended by the Company. However, the Company has credit protection in the form of indemnification agreements, guarantees, and collateral arrangements. The Company has evaluated the variable interests held by the Company in each CDE (NMTC) investment and determined the Company does not individually meet the characteristics of a primary beneficiary; however, the related-party group does meet the criteria as a group and substantially all of the activities of the CDEs either involve or are conducted on behalf of the Company. As a result, the Company is the primary beneficiary of the CDEs and their assets, liabilities, and results of operations are included in the Company’s consolidated financial statements. The primary activities of the CDEs are recognized in commercial loans interest income and other borrowed funds interest expense on the Company’s statements of operations and the federal income tax credit allocations from the investments are recognized in the Company’s statements of operations as a component of income tax expense. Such related cash flows are recognized in loans originated, principal collected on loans and change in other borrowed funds.

The following table summarizes the carrying amounts of the consolidated VIEs’ assets and liabilities included in the Company’s statements of financial condition and 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.

Unconsolidated Variable Interest Entities

The Company has equity investments in Low-Income Housing Tax Credit (“LIHTC”) partnerships with carrying values of $8,127,000 and $7,282,000 as of September 30, 2017 and December 31, 2016 , respectively. The LIHTCs are indirect federal subsidies to finance low-income housing and are used in connection with both newly constructed and renovated residential rental buildings. Once a project is placed in service, it is generally eligible for the tax credit for ten consecutive years. To continue generating the tax credit and to avoid tax credit recapture, a LIHTC building must satisfy specific low-income housing compliance rules for a full fifteen -year period. The maximum exposure to loss in the VIEs is the amount of equity invested and credit extended by the Company. However, the Company has credit protection in the form of indemnification agreements, guarantees, and collateral arrangements. The Company has evaluated the variable interests held by the Company in each LIHTC investment and determined that the Company does not have controlling financial interests in such investments, and is not the primary beneficiary. The Company reports the investments in the unconsolidated LIHTCs as other assets on the Company’s statements of financial condition. Total unfunded contingent commitments related to the Company’s LIHTC investments totaled $23,283,000 at September 30, 2017 , of which $14,947,000 is expected to be fulfilled in 2017 and $8,336,000 is expected to be fulfilled in 2018 . There were no impairment losses on the Company’s LIHTC investments during the nine months ended September 30, 2017 .

The Company has elected to use the proportional amortization method for the amortization of all eligible LIHTC investments and amortization expense is recognized as a component of income tax expense. The following table summarizes the amortization expense and the amount of tax credits and other tax benefits recognized for qualified affordable housing project investments during the periods presented.



	Three Months ended			Nine Months ended
(Dollars in thousands)	September 30, 2017		September 30, 2016	September 30, 2017	September 30, 2016
Amortization expense	$	682	258	1,825	867
Tax credits and other tax benefits recognized	1,040		322	2,792	1,145

The Company also 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 have no assets, operations, revenues or cash flows other than those related to the issuance, administration and repayment of the securities held by third parties. The trust subsidiaries are not included in the Company’s consolidated financial statements because the sole asset of each trust subsidiary is a receivable from the Company, even though the Company owns all of the voting equity shares of the trust subsidiaries, has fully guaranteed the obligations of the trust subsidiaries and may have the right to redeem the third party securities under certain circumstances. The Company reports the trust preferred securities issued to the trust subsidiaries as subordinated debentures on the Company’s statements of financial condition.

Note 6. Securities Sold Under Agreements to Repurchase

The Company’s securities sold under agreements to repurchase (“repurchase agreements”) totaled $453,596,000 and $473,650,000 at September 30, 2017 and December 31, 2016 , respectively, and are secured by investment securities with carrying values of $528,791,000 and $472,239,000 , respectively. Securities are pledged to customers at the time of the transaction in an amount at least equal to the outstanding balance and are held in custody accounts by third parties. The fair value of collateral is continually monitored and additional collateral is provided as deemed appropriate.

The following tables summarize the carrying value of the Company’s repurchase agreements by remaining contractual maturity and category of collateral:



	September 30, 2017
	Remaining Contractual Maturity of the Agreements
(Dollars in thousands)	Overnight and Continuous		Up to 30 Days	Total
U.S. government and federal agency	$	4,261	—	4,261

Total	$	473,007	643	473,650

Note 7. Derivatives and Hedging Activities

As of September 30, 2017 , the Company’s interest rate swap 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		Payment Term
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 counterparty pays the Company the variable interest rate.

The hedging strategy converts the LIBOR-based variable interest rate on borrowings to a fixed interest rate, thereby protecting the Company from interest rate variability.

The interest rate swaps with the $160,000,000 and $100,000,000 notional amounts began their payment terms in October 2014 and November 2015, respectively. The Company designated wholesale deposits and Federal Home Loan Bank (“FHLB”) advances as the cash flow hedge and these hedged items were determined to be fully effective during the current and prior year. As such, no amount of ineffectiveness has been included in the Company’s statements of operations for the nine months ended September 30, 2017 and 2016 . Therefore, the aggregate fair value of the interest rate swaps was recorded in other liabilities with changes recorded in other comprehensive income (“OCI”). The Company expects the hedges to remain highly effective during the remaining terms of the interest rate swaps. Interest expense recorded on the interest rate swaps totaled $5,993,000 and $6,015,000 for the nine months ended September 30, 2017 and 2016 , respectively, and is reported as a component of interest expense on deposits and FHLB advances. Unless the interest rate swaps are terminated during the next year, the Company expects $4,494,000 of the unrealized loss reported in other comprehensive income at September 30, 2017 to be reclassified to interest expense during the next twelve months.

The following table presents the pre-tax gains or losses recorded in accumulated other comprehensive income and the Company’s statements of operations relating to the interest rate swap derivative financial instruments:



	Three Months ended					Nine Months ended
(Dollars in thousands)	September 30, 2017			September 30, 2016		September 30, 2017		September 30, 2016

Interest rate swaps	$	12,748	—	12,748	14,725	—	14,725

Pursuant to the interest rate swap agreements, the Company pledged collateral to the counterparty in the form of investment securities totaling $25,122,000 at September 30, 2017 . There was $0 collateral pledged from the counterparty to the Company as of September 30, 2017 . There is the possibility that the Company may need to pledge additional collateral in the future if there were declines in the fair value of the interest rate swap derivative financial instruments versus the collateral pledged.

Note 10. 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 restricted stock awards were vested, using the treasury stock method.

Basic and diluted earnings per share has been computed based on the following:



	Three Months ended			Nine Months ended
(Dollars in thousands, except per share data)	September 30, 2017		September 30, 2016	September 30, 2017	September 30, 2016
Net income available to common stockholders, basic and diluted	$	36,479	30,957	101,421	90,090
Average outstanding shares - basic	78,004,450		76,288,640	77,379,514	76,195,550
Add: dilutive restricted stock awards	61,492		62,233	63,430	51,501
Average outstanding shares - diluted	78,065,942		76,350,873	77,442,944	76,247,051
Basic earnings per share	$	0.47	0.40	1.31	1.18
Diluted earnings per share	$	0.47	0.40	1.31	1.18

There were 0 and 10,677 restricted stock awards excluded from the diluted average outstanding share calculation for the nine months ended September 30, 2017 and 2016 , respectively. Anti-dilution occurs when the unrecognized compensation cost per share of a restricted stock award exceeds the market price of the Company’s stock.

Note 11. 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 nine month periods ended September 30, 2017 and 2016 .

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 September 30, 2017 .

Investment securities, available-for-sale: 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, market spreads, prepayments, defaults, recoveries, 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.

Fair value determinations of available-for-sale securities are the responsibility of the Company’s corporate accounting and treasury departments. The Company obtains fair value estimates from independent third party vendors on a monthly basis. The vendors’ pricing system methodologies, procedures and system controls are reviewed to ensure they are appropriately designed and operating effectively. 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. In assessing credit risk, the Company reviews payment performance, collateral adequacy, third party research and analyses, credit rating histories and issuers’ financial statements. For those markets determined to be inactive or limited, the valuation techniques used are models for which management has verified that discount rates are appropriately adjusted to reflect illiquidity and credit risk.

Interest rate swap derivative financial instruments: fair values for interest rate swap derivative financial instruments 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 Fed Funds Effective Swap Rate 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 third party.

The following tables disclose the fair value measurement of assets and liabilities measured at fair value on a recurring basis:



			Fair Value Measurements At the End of the Reporting Period Using

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 September 30, 2017 .

Other real estate owned: OREO is carried at the lower of fair value at acquisition date or current 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.

The following tables disclose the fair value measurement of assets with a recorded change during the period resulting from re-measuring the assets at fair value on a non-recurring basis:

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.

Investment securities, held-to-maturity: fair value for held-to-maturity securities is estimated in the same manner as available-for-sale securities, which is described above.

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 valuation 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 an 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 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.

Securities sold under agreements to repurchase 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.

The following tables present the carrying amounts, estimated fair values and the level within the fair value hierarchy of the Company’s financial instruments:

Note 12. Mergers and Acquisitions

On April 30, 2017 , the Company acquired 100 percent of the outstanding common stock of TFB Bancorp, Inc. and its wholly-owned subsidiary, The Foothills Bank, a community bank based in Yuma, Arizona. Foothills provides banking services to individuals and businesses in Arizona, with banking offices located in Yuma, Prescott and Casa Grande, Arizona. The acquisition expands the Company’s market into the state of Arizona and further diversifies the Company’s loan, customer and deposit base. Foothills merged into Glacier Bank and operates as a separate Bank division under its existing name and management team. The Foothills acquisition was valued at $64,015,000 and resulted in the Company issuing 1,381,661 shares of its common stock and $17,342,000 in cash in exchange for all of Foothills’ outstanding common stock shares. The fair value of the Company shares issued was determined on the basis of the closing market price of the Company’s common stock on the April 30, 2017 acquisition date. The excess of the fair value of consideration transferred over total identifiable net assets was recorded as goodwill. The goodwill arising from the acquisition consists largely of the synergies and economies of scale expected from combining the operations of the Company and Foothills. None of the goodwill is deductible for income tax purposes as the acquisition was accounted for as a tax-free exchange.

The assets and liabilities of Foothills were recorded on the Company’s consolidated statements of financial condition at their estimated fair values as of the April 30, 2017 acquisition date and Foothills’ results of operations have been included in the Company’s consolidated statements of operations since that date.

The following table discloses the calculation of the fair value of the consideration transferred, the total identifiable net assets acquired and the resulting goodwill arising from the Foothills acquisition:

__________

¹ The core deposit intangible for this acquisition was determined to have an estimated life of 10 years .

The fair value of the Foothills assets acquired includes loans with fair values of $292,529,000 and the gross principal and contractual interest due under the Foothills contracts is $303,527,000 . The Company evaluated the principal and contractual interest due at the acquisition date and determined that an insignificant amount is not expected to be collectible.

The Company incurred $877,000 of third-party acquisition-related costs in connection with the Foothills acquisition during the nine months ended September 30, 2017 . The expenses are primarily included in other expense in the Company's consolidated statements of operations.

Total income consisting of net interest income and non-interest income of the acquired operations of Foothills was approximately $8,579,000 and net income was approximately $1,853,000 from April 30, 2017 to September 30, 2017 . The following unaudited pro forma summary presents consolidated information of the Company as if the Foothills acquisition had occurred on January 1, 2016:

Note 13. Subsequent Event

On October 26, 2017, the Company announced the signing of a definitive agreement to acquire Inter-Mountain Bancorp, Inc. and its wholly-owned subsidiary, First Security Bank, a community bank based in Bozeman, Montana (collectively, “FSB”). FSB provides banking services to individuals and businesses throughout Montana with banking offices located in Bozeman, Belgrade, Big Sky, Choteau, Fairfield, Fort Benton, Three Forks, Vaughn and West Yellowstone. As of September 30, 2017, FSB had total assets of $1,009,623,000 , gross loans of $657,626,000 and total deposits of $873,572,000 . Upon closing of the transaction, which is anticipated to take place in the first quarter of 2018, FSB will become a new Bank division headquartered in Bozeman. Big Sky Western Bank, the Bank’s existing Bozeman-based division will combine with the new FSB division. The agriculture-focused northern branches of FSB, located in the area known as the Golden Triangle, will combine with the Bank’s First Bank of Montana division.

The Company is managing its asset size to stay below $10 billion through the remainder of the current year to delay the impact of the Durbin Amendment for one additional year. The Company is accomplishing this strategy by paying down borrowings and wholesale deposits with cash flow from investment securities and the excess cash was redoployed into the higher yielding loan portfolio. The Durbin Amendment, which was passed as part of the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”), establishes limits on the amount of interchange fees that can be charged to merchants for debit card processing and will reduce the Company’s service charges fee income in the future.

Total investment securities of $2.542 billion at September 30, 2017 decreased $260 million, or 9 percent, during the current quarter and decreased $430 million, or 14 percent, from the prior year third quarter. Investment securities represented 26 percent of total assets at September 30, 2017 compared to 33 percent of total assets at December 31, 2016 and 32 percent of total assets at September 30, 2016.

The Company experienced another strong quarter for loan growth with an increase of $164 million, or 10 percent annualized, during the current quarter. The loan category with the largest increase was commercial real estate loans which increased $110 million, or 3 percent. Excluding the Foothills acquisition, the loan portfolio increased $621 million, or 11 percent, since September 30, 2016 with the primary increases coming from growth in commercial real estate and other commercial loans of $354 million and $244 million, respectively.

Core deposits increased $74.5 million, or 1 percent, from the prior quarter, with the largest increase in non-interest bearing deposits which increased $121.9 million, or 5 percent. As part of the strategy to stay below $10 billion in total assets, the Company reduced the amount of wholesale deposits during the current quarter which decreased $105 million, or 36 percent, over the prior quarter. Excluding the Foothills acquisition, core deposits increased $315 million, or 5 percent, from September 30, 2016.

Securities sold under agreements to repurchase (“repurchase agreements”) of $454 million at September 30, 2017 increased $2.5 million, or 1 percent, from the prior quarter and increased $52.4 million, or 13 percent, from the prior year third quarter. Federal Home Loan Bank (“FHLB”) advances of $154 million at September 30, 2017 decreased $57.8 million from the prior quarter as a result of the Company prepaying $50 million of higher cost advances.

Tangible stockholders’ equity of $1.014 billion at September 30, 2017 was stable compared to the prior quarter which was the result of the Company declaring a special and regular quarterly dividend which offset the current quarter net income. Tangible stockholders’ equity increased $25.8 million, or 3 percent, from a year ago, the result of earnings retention and $46.7 million of Company stock issued in connection with the Foothills acquisition; such increases more than offset the increase in goodwill and core deposit intangibles and the decrease in accumulated other comprehensive income. Tangible book value per common share at quarter end decreased $0.04 per share from the prior quarter and increased $0.08 per share from a year ago.

Cash Dividend

On September 11, 2017, the Company’s Board of Directors declared a quarterly cash dividend of $0.21 per share and a special cash dividend of $0.30 per share. The quarterly dividend was payable September 28, 2017 to shareholders of record on September 21, 2017. The special dividend was payable September 29, 2017 to shareholders of record on September 22, 2017. Future cash dividends will depend on a variety of factors, including net income, capital, asset quality, general economic conditions and regulatory considerations.

Net Interest Income

In the current quarter, interest income of $96.5 million increased $2.4 million, or 3 percent, from the prior quarter and increased $10.5 million, or 12 percent, over the prior year third quarter with both increases attributable to the increase in interest from commercial loans. Interest income on commercial loans increased $3.7 million, or 7 percent, from the prior quarter and increased $12.2 million, or 26 percent, from the prior year third quarter. As a result of the shrinking investment portfolio, interest income from investments decreased $1.4 million from the prior quarter and $1.8 million from the prior year third quarter.

The current quarter interest expense of $7.7 million decreased $122 thousand, or 2 percent, from the prior quarter and increased $334 thousand, or 5 percent, from the prior year third quarter. The total cost of funding (including non-interest bearing deposits) for the current quarter was 35 basis points compared to 37 basis points for the prior quarter and 37 basis points for the prior year third quarter.

The Company’s net interest margin as a percentage of earning assets, on a tax-equivalent basis, for the current quarter was 4.11 percent compared to 4.12 percent in the prior quarter. The 1 basis points decrease in the net interest margin was the result of a 3 basis point reduction on the earning asset yield which was partially offset by a 2 basis point reduction in cost of funds. The decrease in earning asset yield was primarily driven by the decrease in higher yielding securities and the decrease in cost of funds was driven by an increase in non-interest bearing deposits and a decrease in borrowings. The current quarter net interest margin increased 11 basis points over the prior year third quarter net interest margin of 4.00 percent, due to the remix of earning assets to higher yielding loans.

Non-interest Income

Non-interest income for the current quarter totaled $31.2 million, an increase of $3.5 million, or 13 percent, from the prior quarter and an increase of $2.9 million, or 10 percent, over the same quarter last year. Service charges and other fees of $17.3 million, decreased by $188 thousand, or 1 percent, from the prior quarter primarily from seasonal activity and increased $1.0 million, or 6 percent, from the prior year third quarter which was driven by the increased number of accounts. Gain on sale of loans for the current quarter increased $1.6 million, or 21 percent, from the prior quarter and decreased $451 thousand, or 5 percent, from the prior year third quarter. Other income of $3.4 million, increased $1.4 million, or 68 percent, over the prior quarter and increased $1.7 million, or 92 percent over the prior year third quarter principally due to the increase in gain on sale of other real estate owned (“OREO”). Gain on sale of OREO during the third quarter of 2017 was $1.5 million compared to $369 thousand in the prior quarter and $134 thousand in the prior year third quarter.

During 2016, the Company consolidated its Bank divisions’ individual core database systems into a single core database and re-issued debit cards with chip technology (the Core Consolidation Project or “CCP”). Expenses related to CCP were $1.4 million during the third quarter of 2016. Excluding CCP expenses, non-interest expense for the current quarter increased $4.8 million, or 7 percent, over the prior year third quarter.

Compensation and employee benefits for the current quarter increased $1.8 million, or 5 percent, from the prior quarter as a result of increased cost of benefits, the Foothills acquisition, and a reduction in deferred compensation from loan production. Compensation and employee benefits increased by $2.9 million, or 8 percent, from the prior year third quarter due to salary increases and the increased number of employees from acquisitions. Data processing expense increased $238 thousand, or 7 percent, from the prior quarter. Data processing expense decreased $335, or 8 percent, from the prior year third quarter as a result of decreased costs associated with CCP. Other expenses increased $693 thousand, or 6 percent from the prior quarter with changes in several categories. Other expense decreased $214 thousand, or 2 percent, from the prior year third quarter as a result of decreased costs associated with CCP.

Efficiency Ratio

The current quarter efficiency ratio was 53.44 percent, a 55 basis points increase from the prior quarter efficiency ratio of 52.89 percent which was the result of an increase in operating expenses that outpaced the increase in net interest income and non-interest income. The current quarter efficiency ratio decreased 240 basis points from the prior year third quarter ratio of 55.84 percent and was attributable to the increase in net interest income primarily due to higher interest income on commercial loans.

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 (Recoveries)			Allowance for Loan and Lease Losses 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

Fourth quarter 2015	411		1,482			2.55	%	0.38	%	0.88	%

Net charge-offs for the current quarter were $3.6 million compared to $2.4 million for the prior quarter and $478 thousand from the same quarter last year. There was $3.3 million of current quarter provision for loan losses, compared to $3.0 million in the prior quarter and $626 thousand in the prior year third quarter. Loan portfolio growth, composition, average loan size, credit quality considerations, and other environmental factors will continue to determine the level of the loan loss provision.

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.”

Net Interest Income

Interest income for the first nine months of the current year increased $21.7 million, or 8 percent, from the prior year first nine months and was principally due to a $26.8 million increase in income from commercial loans which more than offset the decrease of $5.4 million in interest income on investments.

Interest expense of $22.8 million for the first nine months of the current year increased $375 thousand over the the same period in the prior year. The total funding cost (including non-interest bearing deposits) for the first nine months of 2017 was 36 basis points compared to 38 basis points for the first nine months of 2016.

The net interest margin as a percentage of earning assets, on a tax-equivalent basis, for the first nine months of 2017 was 4.09 percent, a 7 basis point increase from the net interest margin of 4.02 percent for the first nine months of 2016. The increase in the margin was primarily attributable to a shift in earning assets to higher yielding loans combined with a continued increase in low cost deposits.

Non-interest Income

Non-interest income of $84.5 million for the first nine months of 2017 increased $5.2 million, or 7 percent, over the same period last year. Service charges and other fees of $50.4 million for the first nine months of 2017 increased $3.7 million, or 8 percent, from the same period last year as a result of an increased number of deposit accounts. The gain on sale of loans of $23.0 million for the first nine months of 2017 decreased $810 thousand, or 3 percent, from the same period last year which was due to a lower volume of refinanced mortgages. Other income of $8.3 million for the first nine months of 2017 increased $2.3 thousand, or 38 percent, over the same period last year and was the result of an increase on gain on sale of OREO.

Non-interest Expense

Expenses related to CCP were $3.6 million during the first nine months of 2016. Excluding CCP expenses, non-interest expense for the current year increased $8.8 million, or 5 percent, over the prior year. Compensation and employee benefits for the first nine months of 2017 increased $7.2 million, or 6 percent, from the same period last year due to salary increases, vesting of restricted stock awards, and the increased number of employees from the acquired banks. Data processing expense decreased $802 thousand, or 7 percent, from the prior year first nine months as a result of decreased costs associated with CCP. Current year other expenses of $34.1 million decreased $1.5 million, or 4 percent, from the prior year and was principally driven by decreased costs associated with CCP.

Efficiency Ratio

The efficiency ratio of 53.92 percent for the first nine months of 2017 decreased 223 basis points from the prior year efficiency ratio of 56.15 percent for the first nine months of 2016 which resulted from the increase in net interest income largely due to higher interest income on commercial loans.

Provision for Loan Losses

The provision for loan losses was $7.9 million for the first nine months of 2017, an increase of $6.7 million from the same period in the prior year. Net charge-offs during the first nine months of 2017 were $7.9 million compared to net recoveries of $1.6 million from the first nine months of 2016.

ADDITIONAL MANAGEMENT’S DISCUSSION AND ANALYSIS

The Company’s investment portfolio is primarily comprised of state and local government securities and mortgage-backed securities. State and local government securities are largely exempt from federal income tax and the Company’s maximum federal statutory rate of 35 percent is used in calculating the tax-equivalent yields on the tax-exempt securities. Mortgage-backed securities are primarily short, weighted-average life U.S. agency guaranteed residential mortgage pass-through securities. To a lesser extent, mortgage-backed securities also consist of short, weighted-average life U.S. agency guaranteed residential collateralized mortgage obligations and U.S. agency guaranteed commercial mortgage-backed securities. Combined, the mortgage-backed securities provide the Company with ongoing liquidity as scheduled and pre-paid principal is received on the securities.

State and local government securities carry different risks that are not as prevalent in other security types. The Company evaluates the investment grade quality of its securities in accordance with regulatory guidance. Investment grade securities are those where the issuer has an adequate capacity to meet the financial commitments under the security for the projected life of the investment. An issuer has an adequate capacity to meet financial commitments if the risk of default by the obligor is low and the full and timely payment of principal and interest are expected. In assessing credit risk, the Company may use credit ratings from Nationally Recognized Statistical Rating Organizations (“NRSRO” entities such as Standard and Poor’s [“S&P”] and Moody’s) as support for the evaluation; however, they are not solely relied upon. There have been no significant differences in the Company’s internal evaluation of the creditworthiness of any issuer when compared with the ratings assigned by the NRSROs.

The following table stratifies the state and local government securities by the associated NRSRO ratings. The highest issued rating was used to categorize the securities in the table for those securities where the NRSRO ratings were not at the same level.

Other-Than-Temporary Impairment on Securities Analysis

Non-marketable equity securities. Non-marketable equity securities largely consist of capital stock issued by the FHLB of Des Moines and are evaluated for impairment whenever events or circumstances suggest the carrying value may not be recoverable. Based on the Company’s evaluation of its investments in non-marketable equity securities as of September 30, 2017 , the Company determined that none of such securities had other-than-temporary impairment.

Debt securities. 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. For debt securities with limited or inactive markets, the impact of macroeconomic conditions in the U.S. upon fair value estimates includes higher risk-adjusted discount rates and changes in credit ratings provided by NRSRO. In June 2017, S&P issued a credit opinion confirming its AA+ rating of U.S. government long-term debt, and the outlook remains stable. In June 2017, Moody's issued a credit opinion confirming its Aaa rating of U.S. government long-term debt and the outlook remains stable. In April 2017, Fitch issued a credit opinion confirming its AAA rating of U.S. government long-term debt and the outlook remains stable. S&P, Moody's and Fitch have similar credit ratings and outlooks with respect to certain long-term debt instruments issued by Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”) and other U.S. government agencies linked to the long-term U.S. debt.

The following table separates investments with an unrealized loss position at September 30, 2017 into two categories: investments purchased prior to 2017 and those purchased during 2017 . Of those investments purchased prior to 2017 , the fair market value and unrealized gain or loss at December 31, 2016 is also presented.

With respect to the duration of the impaired debt securities, the Company identified 197 securities which have been continuously impaired for the twelve months ending September 30, 2017 . The valuation history of such securities in the prior year(s) was also reviewed to determine the number of months in the prior year(s) in which the identified securities were in an unrealized loss position.

The following table provides details of the 197 debt securities which have been continuously impaired for the twelve months ended September 30, 2017 , including the most notable loss for any one bond in each category.

Based on the Company's analysis of its impaired debt securities as of September 30, 2017 , the Company determined that none of such securities had other-than-temporary impairment and the unrealized losses were primarily the result of interest rate changes and market spreads subsequent to acquisition. A substantial portion of the debt securities with unrealized losses at September 30, 2017 were issued by Fannie Mae, Freddie Mac, Government National Mortgage Association (“Ginnie Mae”) and other agencies of the U.S. government or have credit ratings issued by one or more of the NRSRO entities in the four highest credit rating categories. All of the Company's impaired debt securities at September 30, 2017 have been determined by the Company to be investment grade.

Lending Activity

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, including agriculture and public entities; and 3) installment lending for consumer purposes (e.g., home equity, automobile, 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 are based on the purpose of the loan, unless otherwise noted as a regulatory classification. The following table summarizes the Company’s loan portfolio as of the dates indicated:

Non-performing assets at September 30, 2017 were $65.1 million, a decrease of $3.8 million, or 6 percent, from the prior quarter and a decrease of $13.2 million, or 17 percent, from a year ago. Non-performing assets as a percentage of subsidiary assets at September 30, 2017 was 0.67 percent which was a decrease of 17 basis points from the prior year third quarter of 0.84 percent. Early stage delinquencies (accruing loans 30-89 days past due) of $29.1 million at September 30, 2017 decreased $2.0 million from the prior quarter and increased $1.7 million from the prior year third quarter.

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 losses to the Company. The Company evaluates the level of its non-performing loans, the values of the underlying real estate and other collateral, and related trends in internal and external environmental factors and 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.

In prior years, construction loans, a regulatory classification, accounted for a significant portion of the Company’s non-accrual loans. As a result of the gradual economic recovery and the Company’s diligent focus on this category of non-performing loans, construction loans only accounted for 24 percent of the Company’s non-accrual loans as of September 30, 2017 . With very limited exceptions, 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.

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 $123 million and $130 million as of September 30, 2017 and December 31, 2016 , respectively. The ALLL includes specific valuation allowances of $4.1 million and $6.9 million of impaired loans as of September 30, 2017 and December 31, 2016 , respectively.

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. 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 loans are designated as TDRs. The Company’s TDR loans of $53.2 million and $73.8 million as of September 30, 2017 and December 31, 2016 , respectively, are considered impaired loans.

Other Real Estate Owned

The book value of loans prior to the acquisition of collateral and transfer of the loans into OREO during 2017 was $5.2 million . The fair value of the loan collateral acquired in foreclosure during 2017 was $3.8 million . 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, trends and changes in collateral values, delinquencies, non-performing assets, net charge-offs and credit-related policies and personnel. 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 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 historical 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 allowance and reviews and approves the overall ALLL. 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 loans collectively evaluated for impairment 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 includes fourteen Bank divisions with separate management teams providing 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 this slowly improving, but fragile economic recovery and 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.

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 (recoveries) as a percentage of total loans	0.12		%	0.07	%	0.04	%	(0.03	)%

The ALLL as a percentage of total loans outstanding at September 30, 2017 was 1.99 percent, a decrease of 29 basis points from 2.28 percent at December 31, 2016 which was driven by loan growth, stabilizing credit quality, and no allowance carried over from the Foothills acquisition as a result of the acquired loans recorded at fair value.

The Company’s ALLL of $130 million is considered adequate to absorb losses from any class of its loan portfolio. For the periods ended September 30, 2017 and 2016 , the Company believes the ALLL 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.

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 2017 , the provision for loan losses exceeded loan charge-offs, net of recoveries, by $4 thousand . During the same period in 2016 , the provision for loan losses exceeded loan charge-offs, net of recoveries, by $2.8 million .

The Company provides commercial services to individuals, small to medium-sized businesses, community organizations and public entities from 145 locations, including 136 branches, across Montana, Idaho, Utah, Washington, Wyoming, Colorado and Arizona. The states in which the Company operates have 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.

Overall, there continues to be slow improvements in the economic environment compared to the past several years and the housing market is slowly recovering. Home prices continue to increase in all of the states within the Company’s footprint. Colorado, Idaho and Washington are experiencing the strongest pricing pressures, while Wyoming and Montana continue to lag behind the national trend. Five of the Company’s states are ranked in the top 10 nationally for house price appreciation. Home ownership in the United States has continually declined since 2008; however, there have been recent periods of increased home ownership during the second half of 2015, the second half of 2016 and the second quarter of 2017. The long-term average for the United States homeownership rate is at 65.3 percent. Quarterly personal income growth remains in positive territory for each of the Company’s states, except for Wyoming, while Washington, Arizona, Colorado, Idaho and Utah exceed the national average. The Federal Reserve Bank of Philadelphia’s composite state coincident indices projects steady growth in Washington, Arizona, Idaho, Wyoming and Colorado during the next six months, while growth in Montana and Utah is expected to remain steady. During the second quarter of 2017, the United States economy grew at its strongest pace in two years as profits from current production increased. All of the states in the Company’s footprint have unemployment rates at or below 5 percent, which reflects the Federal Reserve’s definition of full employment. Crude oil, natural gas and base metal prices have all tapered off or decreased slightly and certain agriculture commodities within the Company’s footprint remain volatile. The tourism industry and related lodging activity continues to be a source of strength for locations where the Company’s markets include national parks and similar recreational areas. However, Canadian tourism in Washington, Idaho and Montana has been negatively impacted by the weak Canadian dollar. Overall, the Company sees positive signs in the various economic indices; however, given the significant recession experienced during 2008 and 2009, the Company is cautiously optimistic about the subsequent recovery of the housing industry. The Company will continue to actively monitor the economy’s impact on its lending portfolio.

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 were 13 percent of the Company’s total loan portfolio and accounted for 24 percent and 20 percent of the Company’s non-accrual loans at September 30, 2017 and December 31, 2016 , respectively. Collateral securing construction loans includes residential buildings (e.g., single/multi-family and condominiums), commercial buildings, and associated land (e.g., multi-acre parcels and individual lots, with and without shorelines).

The Company’s ALLL consisted of the following components as of the dates indicated:



(Dollars in thousands)	September 30, 2017		June 30, 2017	December 31, 2016	September 30, 2016
Specific valuation allowance	$	4,077	3,081	6,881	5,966
General valuation allowance	125,499		126,796	122,691	126,568
Total ALLL	$	129,576	129,877	129,572	132,534

During 2017 , the ALLL increased by $4 thousand , the net result of a $2.8 million decrease in the specific valuation allowance and a $2.8 million increase in the general valuation allowance. The specific valuation allowance decreased as the result of a $4.2 million decrease in loans individually evaluated for impairment with a specific impairment. The increase in the general valuation allowance since the prior year end was a result of an increase of $534 million in loans collectively evaluated for impairment, excluding the current year acquisition. At acquisition date, the assets and liabilities of the acquired banks are recorded at their estimated fair values which results in no ALLL carried over on loans from acquired banks.

For additional information regarding the ALLL, its relation to the provision for loan losses and risk related to asset quality, see Note 3 to the Consolidated Financial Statements in “Part I. Item 1. Financial Statements.”

Loans by Regulatory Classification

Supplemental information regarding identification of the Company’s loan portfolio and credit quality based on regulatory classification is provided in the following tables. The regulatory classification of loans is based primarily on the type of collateral for the loans. There may be differences when compared to loan tables and loan amounts appearing elsewhere which reflect the Company’s internal loan segments and classes which are based on the purpose of the loan.

The following table summarizes the Company’s loan portfolio by regulatory classification:

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 also obtains funds from repayment of loans and investment securities, repurchase agreements, wholesale deposits, advances from FHLB and other borrowings. 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, match maturities of longer-term assets or manage interest rate risk.

Deposits

The Company has several 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 NOW and demand accounts, savings, money market deposit accounts, fixed rate certificates of deposit with maturities ranging from three months to five years, negotiated-rate jumbo certificates, and individual retirement accounts. These deposits are obtained primarily from individual and business residents in the Bank’s geographic market areas. In addition, wholesale deposits are obtained through various programs and include brokered deposits classified as NOW, DDA, money market deposit and certificate accounts. The Company’s deposits are summarized below:



	September 30, 2017				December 31, 2016				September 30, 2016

Securities Sold Under Agreements to Repurchase, Federal Home Loan Bank Advances and Other Borrowings

The Company borrows money through repurchase agreements. This process involves the selling of one or more of the securities in the Company’s investment portfolio and simultaneously entering into an agreement to repurchase that same securities at an agreed upon later date, typically overnight. A rate of interest is paid for the agreed period of time. Through a policy adopted by the Bank’s Board of Directors, the Bank enters into repurchase agreements with local municipalities, and certain customers, and has adopted procedures designed to ensure proper transfer of title and safekeeping of the underlying securities. In addition to retail repurchase agreements, the Company periodically enters into wholesale repurchase agreements as additional funding sources. The Company has not entered into reverse repurchase agreements.

The Bank is a member of the FHLB of Des Moines, which is one of eleven banks that comprise the FHLB system. The Bank is required to maintain a certain level of activity-based stock in order to borrow or to engage in other transactions with the FHLB of Des Moines. Additionally, the Bank is subject to a membership capital stock requirement that is based upon an annual calibration tied to the total assets of the Bank. The borrowings are collateralized by eligible categories of loans and investment securities (principally, securities which are obligations of, or guaranteed by, the U.S. government and its agencies), provided certain standards related to credit-worthiness have been met. Advances are made pursuant to several different credit programs, each of which has its own interest rates and range of maturities. The Bank’s maximum amount of FHLB advances is limited to the lesser of a fixed percentage of the Bank’s total assets or the discounted value of eligible collateral. FHLB advances fluctuate to meet seasonal and other withdrawals of deposits and to expand lending or investment opportunities of the Company.

Additionally, the Company has other sources of secured and unsecured borrowing lines from various sources that may be used from time to time.

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 Bank’s 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 (“FRB”). FHLB advances and certain other short-term borrowings may be renewed 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 and other risks.

The following table provides information relating to significant short-term borrowings, which consists of borrowings that mature within one year of period end:



	At or for the Nine Months ended			At or for the Year ended
(Dollars in thousands)	September 30, 2017			December 31, 2016
Repurchase agreements
Amount outstanding at end of period	$	453,596		473,650
Weighted interest rate on outstanding amount	0.57		%	0.34	%
Maximum outstanding at any month-end	$	497,187		473,650
Average balance	$	425,864		384,066
Weighted-average interest rate	0.43		%	0.31	%

Subordinated Debentures

In addition to funds obtained in the ordinary course of business, the Company formed or acquired financing subsidiaries for the purpose of issuing trust preferred securities that entitle the investor to receive cumulative cash distributions thereon. The subordinated debentures outstanding as of September 30, 2017 were $126 million , including fair value adjustments from prior acquisitions.

Contractual Obligations and Off-Balance Sheet Arrangements

In the normal course of business, there may be various outstanding commitments to obtain funding 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.

Off-balance sheet arrangements also include any obligation related to a variable interest held in an unconsolidated entity. The Company does not anticipate any material losses as a result of these transactions. For additional information regarding the Company’s interests in unconsolidated variable interest entities (“VIE”), see Note 5 to the Consolidated Financial Statements in “Part I. Item 1. Financial Statements.”

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; and


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

The Company has a wide range of versatility in managing the liquidity and asset/liability mix. The Bank’s ALCO 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, including off-balance sheet funding sources. The Company evaluates its potential funding needs across alternative scenarios and maintains contingency funding plans consistent with the Company’s access to diversified sources of contingent funding.

The following table identifies certain liquidity sources and capacity available to the Company as of the dates indicated:



(Dollars in thousands)	September 30, 2017			December 31, 2016

Total unencumbered securities	$	845,720		1,222,412

Capital Resources

Maintaining capital strength continues to be a long-term objective of the Company. 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. The Company has the capacity to issue 117,187,500 shares of common stock of which 78,006,956 have been issued as of September 30, 2017 . The Company also has the capacity to issue 1,000,000 shares of preferred stock of which none have been issued as of September 30, 2017 . Conversely, the Company may decide to utilize a portion of its strong capital position, as it has done in the past, to repurchase shares of its outstanding common stock, depending on market price and other relevant considerations.

The Federal Reserve has adopted capital adequacy guidelines that are used to assess the adequacy of capital in supervising a bank holding company. The federal banking agencies implemented final rules (“Final Rules”) to establish a new comprehensive regulatory capital framework with a phase-in period beginning on January 1, 2015 and ending on January 1, 2019. The Final Rules implemented the third installment of the Basel Accords (“Basel III”) regulatory capital reforms and changes required by the Dodd-Frank Act and substantially amended the regulatory risk-based capital rules applicable to the Company. Under Basel III, the Company must hold a conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer for 2017 is 1.25% . As of September 30, 2017 , management believes the Company and Bank meet all capital adequacy requirements to which they are subject.

The following table illustrates the Bank’s regulatory ratios and the Federal Reserve’s current capital adequacy guidelines as of September 30, 2017 . The Federal Reserve’s fully phased-in guidelines applicable in 2019 are also summarized.



	Total Capital (To Risk-Weighted Assets)		Tier 1 Capital (To Risk-Weighted Assets)		Common Equity Tier 1 (To Risk-Weighted Assets)		Leverage Ratio/ Tier 1 Capital (To Average Assets)
Glacier Bank’s actual regulatory ratios	15.11	%	13.86	%	13.86	%	11.26	%
Minimum capital requirements	8.00	%	6.00	%	4.50	%	4.00	%
Well capitalized requirements	10.00	%	8.00	%	6.50	%	5.00	%
Minimum capital requirements, including fully-phased in capital conservation buffer (2019)	10.50	%	8.50	%	7.00	%	N/A

There are no conditions or events since September 30, 2017 that management believes have changed the Company’s or Bank’s risk-based capital category.

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.

Under Montana, Idaho, Utah, Colorado and Arizona law, financial institutions are subject to a corporation income tax, which incorporates or is substantially similar to applicable provisions of the Internal Revenue Code. The corporation income tax is imposed on federal taxable income, subject to certain adjustments. State taxes are incurred at the rate of 6.75 percent in Montana, 7.4 percent in Idaho, 5 percent in Utah, 4.63 percent in Colorado and 6.968 percent in Arizona. Washington and Wyoming do not impose a corporate income tax.

Income tax expense for the nine months ended September 30, 2017 and 2016 was $33.3 million and $30.0 million , respectively. The Company’s effective tax rate for the nine months ended September 30, 2017 and 2016 was 24.7 percent and 25.0 percent , respectively. The current and prior year’s low effective tax rates are due to income from tax-exempt investment securities, municipal loans and leases and benefits from federal income tax credits. The income from tax-exempt investment securities, loans and leases was $42.2 million and $43.4 million for the nine months ended September 30, 2017 and 2016 , respectively. The benefits from federal income tax credits were $4.3 million and $2.4 million for the nine months ended September 30, 2017 and 2016 , respectively.

The Company has equity investments in Certified Development Entities (“CDE”) which have received allocations of NMTCs. Administered by the Community Development Financial Institutions Fund (“CDFI 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 (“LIHTC”) 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 of $21.4 million in Qualified Zone Academy and Qualified School Construction bonds whereby the Company receives quarterly federal income tax credits in lieu of taxable interest income. The federal income tax credits on these investment securities 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.

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 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.



	Nine Months ended September 30,
	2017 vs. 2016
	Increase (Decrease) Due to:
(Dollars in thousands)	Volume			Rate		Net
Interest income
Residential real estate loans	$	103		(456	)	(353	)
Commercial loans (tax-equivalent)	27,581			915		28,496
Consumer and other loans	412			285		697
Investment securities (tax-equivalent)	(6,816		)	(1,020	)	(7,836	)
Total interest income	21,280			(276	)	21,004
Interest expense
NOW and DDA accounts	80			106		186
Savings accounts	52			77		129
Money market deposit accounts	151			11		162
Certificate accounts	(560		)	(134	)	(694	)
Wholesale deposits	(435		)	252		(183	)
FHLB advances	(779		)	577		(202	)
Repurchase agreements and other borrowed funds	357			620		977
Total interest expense	(1,134		)	1,509		375
Net interest income (tax-equivalent)	$	22,414		(1,785	)	20,629

Net interest income (tax-equivalent) increased $20.6 million for the nine months ended September 30, 2017 compared to the same period in 2016 . The interest income for the first nine months increased over the same period last year primarily from increased growth of the Company’s commercial loan portfolio. The decrease in interest income on the investment securities portfolio was the result of continuing to redeploy cash flow from investment securities into the loan portfolio. Total interest expense remained relatively flat compared to the prior year with volatility in certain categories including certificate accounts, wholesale deposits, FHLB advances and other borrowed funds.

Effect of inflation and changing prices

Accounting principles generally accepted in the United States of America (“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.


Item 3.	Quantitative and Qualitative Disclosure about Market Risk

The Company’s assessment of market risk as of September 30, 2017 indicates there are no material changes in the quantitative and qualitative disclosures from those in the 2016 Annual Report.


Item 4.	Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company’s Chief Executive Officer and Chief Financial Officer have reviewed and evaluated the effectiveness of the Company’s disclosure controls and procedures (as required by Exchange Act Rules 240.13a-15(b) and 15d-14(c)) as of September 30, 2017 . Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s current disclosure controls and procedures are effective and timely, providing them with material information relating to the Company required to be disclosed in the reports the Company files or submits under the Exchange Act.

Changes in Internal Controls

There have not been any changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the third quarter of 2017 , to which this report relates that have materially affected, or are reasonably likely to materially affect the Company’s internal control over financial reporting.

PART II – OTHER INFORMATION


Item 1.	Legal Proceedings

The Company is involved in various claims, legal actions and complaints which arise in the ordinary course of business. In the Company’s opinion, all such matters are adequately covered by insurance, are without merit or are of such kind, or involve such amounts, that unfavorable disposition would not have a material adverse effect on the financial condition or results of operations of the Company.

Item 1A. Risk Factors

The Company believes there have been no material changes from risk factors previously disclosed in the 2016 Annual Report. The risks and uncertainties described in the 2016 Annual Report should be carefully reviewed. These are not the only risks and uncertainties that the Company faces. Additional risks and uncertainties that the Company does not currently know about or that the Company currently believes are immaterial, or that the Company has not predicted, may also harm its business operations or adversely affect the Company. If any of these risks or uncertainties actually occurs, the Company’s business, financial condition, operating results or liquidity could be adversely affected.
