Note 1. Summary of Significant Accounting Policies

Nature of operations: Independent Bank Group, Inc. (IBG) through its subsidiary, Independent Bank, a Texas state banking corporation (Bank) (collectively known as the Company), provides a full range of banking services to individual and corporate customers in the North, Central and Southeast, Texas areas and along the Colorado Front Range, through its various branch locations in those areas. The Company is engaged in traditional community banking activities, which include commercial and retail lending, deposit gathering, investment and liquidity management activities. The Company’s primary deposit products are demand deposits, money market accounts and certificates of deposit and its primary lending products are commercial business and real estate, real estate mortgage and consumer loans.

Basis of presentation: The accompanying consolidated financial statements include the accounts of IBG and all other entities in which IBG has controlling financial interest. All material intercompany transactions and balances have been eliminated in consolidation. In addition, the Company wholly-owns nine statutory business trusts that were formed for the purpose of issuing trust preferred securities and do not meet the criteria for consolidation.

On January 1, 2019, the Company acquired Guaranty Bancorp (Guaranty) and its wholly owned subsidiary, Guaranty Bank and Trust Company (Guaranty Bank) and its wholly owned subsidiary, Private Capital Management, LLC. Guaranty has been merged into the Company and dissolved and Guaranty Bank and its subsidiary has been merged with the Bank as of acquisition date. The Company also acquired two statutory business trusts in connection with the acquisition as disclosed in Note 5, Other Borrowings and Junior Subordinated Debentures. See Note 13, Business Combinations, for more details of the Guaranty acquisition.

The consolidated interim financial statements are unaudited, but include all adjustments, which, in the opinion of management, are necessary for a fair presentation of the results of the periods presented. All such adjustments were of a normal and recurring nature. These financial statements should be read in conjunction with the financial statements and the notes thereto in the Company's Annual Report on Form10-K for the year ended December 31, 2018. The consolidated balance sheet at December 31, 2018 has been derived from the audited financial statements as of that date, but does not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements.

Segment reporting: The Company has one reportable segment. The Company’s chief operating decision-maker uses consolidated results to make operating and strategic decisions.

Reclassifications: Certain prior period financial statement amounts have been reclassified to conform to current period presentation. The reclassifications have no effect on net income or stockholders' equity as previously reported.

Adoption of new accounting standards: ASU 2016-02, Leases (Topic 842).This ASU, among other things, requires lessees to recognize a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under this guidance, lessor accounting is largely unchanged. This ASU became effective for annual and interim periods for the Company on January 1, 2019. The Company adopted the standard by applying the alternative transition method whereby comparative periods were not restated, and an immaterial cumulative effect adjustment to the opening balance of retained earnings was recognized as of January 1, 2019. The Company also elected the ASU’s package of three practical expedients, which allowed the Company to forego a reassessment of (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) the initial direct costs for any existing leases. The Company also elected not to apply the recognition requirements of the ASU to any short-term leases (as defined by related accounting guidance) and will account for lease and non-lease components separately because such amounts are readily determinable under most lease contracts and because this election results in a lower impact on the Company's balance sheet. The Company has implemented a lease management system to assist in centralizing, maintaining and accounting for all leases and implemented additional processes and internal controls to ensure the Company meets the ASU’s reporting and disclosure requirements. The adoption of this standard resulted in the Company recognizing lease right-of-use assets and related lease liabilities totaling$38,812 and $33,953, respectively, as of January 1, 2019. The difference between the lease assets and the lease liabilities was $4,949 of prepaid rent, which was reclassified to lease assets, and the remainder, net of the deferred tax impact, was recorded as an adjustment to retained earnings in the amount of $70. In addition, the right-of -use assets and related lease liabilities recognized on January 1, 2019 include the leases assumed with the Guaranty acquisition. The adoption of this ASU did not have a significant impact on the Company’s consolidated statement of income. See Note 6, Leases, for required disclosures.

ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities. This ASU requires certain premiums on callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased at a discount is not impacted. Under current GAAP, premiums on callable debt securities are generally amortized over the contractual life of the security. ASU 2017-08 became effective for the Company on January 1, 2019 and, upon adoption, the Company recognized a cumulative effect adjustment reducing retained earnings by $856, net of the deferred tax impact, but otherwise did not have a significant impact to the Company's consolidated financial statements and disclosures.

ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU refines and expand hedge accounting for both financial and commodity risks. Its provisions create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. It also makes certain targeted improvements to simplify the application of hedge accounting guidance. ASU 2017-02 became effective for the Company on January 1, 2019. The adoption of this ASU did not have a significant impact on the Company's consolidated financial statements and disclosures.

ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. This ASU aligns much of the guidance on measuring and classifying nonemployee awards with that of awards to employees. The guidance applies to nonemployee awards issued in exchange for goods or services used or consumed in an entity’s own operations and to awards granted by an investor to employees and nonemployees of an equity method investee for goods or services used or consumed in the investee’s operations. There are no new disclosure requirements. This ASU became effective for the Company on January 1, 2019. The adoption of this ASU did not have a significant impact on the Company’s financial statements and disclosures.

Share repurchase program: The Company established share repurchase programs in prior years which would allow the Company to purchase its common stock in the open market or in privately negotiated transactions. In general, share repurchase programs allow the Company to proactively manage its capital position and return excess capital to shareholders. On October 24, 2018, the Company announced the reestablishment of its share repurchase program. The program authorizes the Company to repurchase up to $75,000 of its common stock. The repurchase program is authorized to continue through October 1, 2019. As of March 31, 2019, the Company repurchased a total of 172,738 shares of Company stock at a total cost of $10,000 under this program. Shares of Company stock repurchased to settle employee tax withholding related to vesting of stock awards during the period ended March 31, 2019 totaled 53,165 at a total cost of $2,507 and were not included under this program.

Subsequent events: Companies are required to evaluate events and transactions that occur after the balance sheet date but before the date the financial statements are issued. They must recognize in the financial statements the effect of all events or transactions that provide additional evidence of conditions that existed at the balance sheet date, including the estimates inherent in the financial statement preparation process. Entities shall not recognize the impact of events or transactions that provide evidence about conditions that did not exist at the balance sheet date but arose after that date. The Company has evaluated subsequent events through the date of filing these financial statements with the Securities and Exchange Commission (SEC) and noted no subsequent events requiring financial statement recognition or disclosure, except as disclosed in Note 14.

Earnings per share: Basic earnings per common share are net income available to common shareholders divided by the weighted average number of common shares outstanding during the period. The unvested share-based payment awards that contain rights to non forfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share include the dilutive effect of additional potential common shares issuable under stock warrants. The participating nonvested common stock was not included in dilutive shares as it was anti-dilutive for the three months ended March 31, 2019 and 2018. Proceeds from the assumed exercise of dilutive stock warrants are assumed to be used to repurchase common stock at the average market price. All stock warrants were exercised as of December 31, 2018.

The following table presents a reconciliation of net income available to common shareholders and the number of shares used in the calculation of basic and diluted earnings per common share.

The Company has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-performing and potential problem loans.

Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. The Company’s management examines current and projected cash flows to determine the ability of the borrower to repay their obligations as agreed. Commercial loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. These cash flows, however, may not be as expected and the value of collateral securing the loans may fluctuate. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short term loans may be made on an unsecured basis. Additionally, our commercial loan portfolio includes loans made to customers in the energy industry, which is a complex, technical and cyclical industry. Experienced bankers with specialized energy lending experience originate our energy loans. Companies in this industry produce, extract, develop, exploit and explore for oil and natural gas. Loans are primarily collateralized with proven producing oil and gas reserves based on a technical evaluation of these reserves. At March 31, 2019 and December 31, 2018, there were approximately $132,432 and $135,034 of energy related loans outstanding, respectively. The Company has a mortgage warehouse purchase program, which provides a mortgage warehouse lending vehicle to third party mortgage bankers across a broad geographic scale. The mortgage loans are underwritten, in part, on approved investor takeout commitments. These loans have a very short duration ranging between 10 days and 15 days. In some cases, loans to larger mortgage originators may be financed for up to 60 days. These loans are reported as commercial loans since the loans are secured by notes receivable, not real estate. As of March 31, 2019 and December 31, 2018, mortgage warehouse purchase loans outstanding totaled $251,258 and $170,290, respectively.

Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts, and the repayment of these loans is generally largely dependent on the successful operation of the property or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The properties securing the Company’s commercial real estate portfolio are diverse in terms of type and geographic location. Management monitors the diversification of the portfolio on a quarterly basis by type and geographic location. Management also tracks the level of owner occupied property versus non owner occupied property. At March 31, 2019, the portfolio consisted of approximately 31% of owner occupied property.

Land and commercial land development loans are underwritten using feasibility studies, independent appraisal reviews and financial analysis of the developers or property owners. Generally, borrowers must have a proven track record of success. Commercial construction loans are generally based upon estimates of cost and value of the completed project. These estimates may not be accurate. Commercial construction loans often involve the disbursement of substantial funds with the repayment dependent on the success of the ultimate project. Sources of repayment for these loans may be pre-committed permanent financing or sale of the developed property. The loans in this portfolio are geographically diverse and due to the increased risk are monitored closely by management and the board of directors on a quarterly basis.

Residential real estate and single family interim construction loans are underwritten primarily based on borrowers’ credit scores, documented income and minimum collateral values. Relatively small loan amounts are spread across many individual borrowers, which minimizes risk in the residential portfolio. In addition, management evaluates trends in past dues and current economic factors on a regular basis.

Agricultural loans are collateralized by real estate and/or agricultural-related assets. Agricultural real estate loans are primarily comprised of loans for the purchase of farmland. Loan-to-value ratios on loans secured by farmland generally do not exceed 80% and have amortization periods limited to twenty years. Agricultural non-real estate loans are generally comprised of term loans to fund the purchase of equipment, livestock and seasonal operating lines to grain farmers to plant and harvest corn and soybeans. Specific underwriting standards have been established for agricultural-related loans including the establishment of projections for each operating year based on industry developed estimates of farm input costs and expected commodity yields and prices. Operating lines are typically written for one year and secured by the crop and other farm assets as considered necessary.

Agricultural loans carry significant credit risks as they involve larger balances concentrated with single borrowers or groups of related borrowers. In addition, repayment of such loans depends on the successful operation or management of the farm property securing the loan or for which an operating loan is utilized. Farming operations may be affected by adverse weather conditions such as drought, hail or floods that can severely limit crop yields.

Consumer loans represent less than 1% of the outstanding total loan portfolio. Collateral consists primarily of automobiles and other personal assets. Credit score analysis is used to supplement the underwriting process.

Most of the Company’s lending activity occurs within the State of Texas, primarily in the north, central and southeast Texas regions and the State of Colorado, specifically along the Front Range area. As of March 31, 2019, loans in the Colorado region represented about 31% of the total portfolio. A large percentage of the Company’s portfolio consists of commercial and residential real estate loans. As of March 31, 2019 and December 31, 2018, there were no concentrations of loans related to a single industry in excess of 10% of total loans.

The allowance for loan losses is an amount that management believes will be adequate to absorb estimated losses relating to specifically identified loans, as well as probable credit losses inherent in the balance of the loan portfolio.

The allowance is derived from the following two components: 1) allowances established on individual impaired loans, which are based on a review of the individual characteristics of each loan, including the customer’s ability to repay the loan, the underlying collateral values and the industry the customer operates and 2) allowances based on actual historical loss experience for the last three years for similar types of loans in the Company’s loan portfolio adjusted for primarily changes in the lending policies and procedures; collection, charge-off and recovery practices; nature and volume of the loan portfolio; change in value of underlying collateral; volume and severity of nonperforming loans; existence and effect of any concentrations of credit and the level of such concentrations and current, national and local economic and business conditions. This second component also includes an unallocated allowance to cover uncertainties that could affect management’s estimate of probable losses. The unallocated allowance reflects the imprecision inherent in the underlying assumptions used in the methodologies for estimating this component.

The Company’s management continually evaluates the allowance for loan losses determined from the allowances established on individual loans and the amounts determined from historical loss percentages adjusted for the qualitative factors above. Should any of the factors considered by management change, the Company’s estimate of loan losses could also change and would affect the level of future provision expense. While the calculation of the allowance for loan losses utilizes management’s best judgment and all the information available, the adequacy of the allowance for loan losses is dependent on a variety of factors beyond the Company’s control, including, among other things, the performance of the entire loan portfolio, the economy, changes in interest rates and the view of regulatory authorities towards loan classifications.

In addition, regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses, and may require the Bank to make additions to the allowance based on their judgment about information available to them at the time of their examinations.

Loans requiring an allocated loan loss provision are generally identified at the servicing officer level based on review of weekly past due reports and/or the loan officer’s communication with borrowers. In addition, past due loans are discussed at weekly officer loan committee meetings to determine if classification is warranted. The Company’s credit department has implemented an internal risk based loan review process to identity potential internally classified loans that supplements the annual independent external loan review. The external review generally covers all loans greater than $4,125 annually. These reviews include analysis of borrower’s financial condition, payment histories and collateral values to determine if a loan should be internally classified. Generally, once classified, an impaired loan analysis is completed by the credit department to determine if the loan is impaired and the amount of allocated allowance required.

The Texas and Colorado economies, specifically the Company’s lending area of north, central and southeast Texas and the Colorado Front Range area, continued to expand during the first quarter of 2019, though at a slower pace than experienced in 2018. The Texas economy, which is the second largest in the nation, and the Colorado economy are above the U.S. economy in job creation and employment growth. Overall, the forecast is positive with continued moderate growth in the manufacturing and service sectors and rising activity in the energy sector. The Texas and Colorado economies are expected to continue to grow in 2019; however, the pace of expansion is expected to slow as the stimulative impacts of federal tax cuts fade and labor shortages and a slowing global economy constrain growth. The risk of loss associated with all segments of the portfolio could increase due to these factors.

The economy and other risk factors are minimized by the Company’s underwriting standards, which include the following principles: 1) financial strength of the borrower including strong earnings, high net worth, significant liquidity and acceptable debt to worth ratio, 2) managerial business competence, 3) ability to repay, 4) loan to value, 5) projected cash flow and 6) guarantor financial statements as applicable. The following is a summary of the activity in the allowance for loan losses by loan class for the three months ended March 31, 2019 and 2018:

The accrual of interest is discontinued on a loan when management believes after considering collection efforts and other factors that the borrower's financial condition is such that collection of interest is doubtful. All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. Cash collections on nonaccrual loans are generally credited to the loan receivable balance, and no interest income is recognized on those loans until the principal balance has been collected. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Impaired loans are those loans where it is probable that all amounts due according to contractual terms of the loan agreement will not be collected. The Company has identified these loans through its normal loan review procedures. Impaired loans are measured based on 1) the present value of expected future cash flows discounted at the loans effective interest rate; 2) the loan's observable market price; or 3) the fair value of collateral if the loan is collateral dependent. Substantially all of the Company’s impaired loans are measured at the fair value of the collateral. In limited cases, the Company may use the other methods to determine the level of impairment of a loan if such loan is not collateral dependent.

All commercial, real estate, agricultural loans and troubled debt restructurings are considered for individual impairment analysis. Smaller balance consumer loans are collectively evaluated for impairment.

Certain impaired loans have adequate collateral and do not require a related allowance for loan loss.

The Company will charge-off that portion of any loan which management considers a loss. Commercial and real estate loans are generally considered for charge-off when exposure beyond collateral coverage is apparent and when no further collection of the loss portion is anticipated based on the borrower’s financial condition.

The restructuring of a loan is considered a “troubled debt restructuring” if both 1) the borrower is experiencing financial difficulties and 2) the creditor has granted a concession. Concessions may include interest rate reductions or below market interest rates, principal forgiveness, extending amortization and other actions intended to minimize potential losses.

A “troubled debt restructured” loan is identified as impaired and measured for credit impairment as of each reporting period in accordance with the guidance in Accounting Standards Codification (ASC) 310-10-35. Modifications primarily relate to extending the amortization periods of the loans and interest rate concessions. The majority of these loans were identified as impaired prior to restructuring; therefore, the modifications did not materially impact the Company’s determination of the allowance for loan losses. The recorded investment in troubled debt restructurings, including those on nonaccrual, was $1,895 and $1,925 as of March 31, 2019 and December 31, 2018, respectively.

There were no loans modified under troubled debt restructurings during the three months ended March 31, 2019 and 2018.

At March 31, 2019 and 2018, there were no loans modified under troubled debt restructurings during the previous twelve month period that subsequently defaulted during the three months ended March 31, 2019 and 2018, respectively. At March 31, 2019 and 2018, the Company had no commitments to lend additional funds to any borrowers with loans whose terms have been modified under troubled debt restructurings.

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. The following table presents information regarding the aging of past due loans by loan class as of March 31, 2019 and December 31, 2018:

The Company’s internal classified report is segregated into the following categories: 1) Pass/Watch, 2) Special Mention, 3) Substandard and 4) Doubtful. The loans placed in the Pass/Watch category reflect the Company’s opinion that the loans reflect potential weakness that requires monitoring on a more frequent basis. The loans in the Special Mention category reflect the Company’s opinion that the credit contains weaknesses which represent a greater degree of risk and warrant extra attention. These loans are reviewed monthly by officers and senior management to determine if a change in category is warranted. The loans placed in the Substandard category are considered to be potentially inadequately protected by the current debt service capacity of the borrower and/or the pledged collateral. These credits, even if apparently protected by collateral value, have shown weakness related to adverse financial, managerial, economic, market or political conditions, which may jeopardize repayment of principal and interest. There is a possibility that some future loss could be sustained by the Company if such weakness is not corrected. The Doubtful category includes loans that are in default or principal exposure is probable. Substandard and Doubtful loans are individually evaluated to determine if they should be classified as impaired and an allowance is allocated if deemed necessary under ASC 310-10.

The loans that are not impaired are included with the remaining “pass” credits in determining the portion of the allowance for loan loss based on historical loss experience and other qualitative factors. The portfolio is segmented into categories including: commercial loans, consumer loans, commercial real estate loans, residential real estate loans and agricultural loans. The adjusted historical loss percentage is applied to each category. Each category is then added together to determine the allowance allocated under ASC 450-20.

A summary of loans by credit quality indicator by class as of March 31, 2019 and December 31, 2018, is as follows:

The Company has included PCI loans in the above grading tables. The following provides additional detail on the grades applied to those loans at March 31, 2019 and December 31, 2018:



	Pass		Pass/ Watch		Special Mention		Substandard		Doubtful		Total
March 31, 2019	$	325,888	$	63,295	$	19,605	$	28,966	$	1	$	437,755
December 31, 2018	40,940		32,427		14,817		24,250		—		112,434

PCI loans may remain on accrual status to the extent the company can reasonably estimate the amount and timing of expected future cash flows. At March 31, 2019 and December 31, 2018, nonaccrual PCI loans were $8,926 and $6,996, respectively.

Accretion on PCI loans is based on estimated future cash flows, regardless of contractual maturity. The following table summarizes the outstanding balance and related carrying amount of purchased credit impaired loans by acquired bank as of the acquisition date for the acquisitions occurring in 2019 and 2018:



	Acquisition Date
	January 1, 2019			June 1, 2018
	Guaranty Bancorp*			Integrity Bancshares, Inc.
Outstanding balance	$	391,089		$	57,317
Nonaccretable difference	(17,543		)	(9,969		)
Accretable yield	(14,704		)	(128		)
Carrying amount	$	358,842		$	47,220

* Amounts represent provisional estimates and are subject to final acquisition accounting adjustments.

The carrying amount of all acquired PCI loans included in the consolidated balance sheet and the related outstanding balance at March 31, 2019 and December 31, 2018 were as follows:



	March 31, 2019		December 31, 2018
Outstanding balance	$	483,754	$	129,333
Carrying amount	437,755		112,434

There was an allocation of $42 and $45 established in the allowance for loan losses relating to PCI loans at March 31, 2019 and December 31, 2018, respectively.

The changes in accretable yield during the three months ended March 31, 2019 and 2018 in regard to loans transferred at acquisition for which it was probable that all contractually required payments would not be collected are presented in the table below.

Note 5. Other Borrowings and Junior Subordinated Debentures

Other borrowings totaled $198,425 and $137,316 at March 31, 2019 and December 31, 2018, respectively. Junior subordinated debentures totaled $53,676 and $27,852 at March 31, 2019 and December 31, 2018, respectively.

In connection with the Guaranty acquisition on January 1, 2019 as further explained in Note 13, Business Combinations, the Company assumed $40,000 in aggregate principal of 5.75% fixed and floating rate subordinated notes due July 20, 2026 and trust preferred securities totaling $25,774 issued under two wholly-owned statutory business trusts, Guaranty Capital Trust III and Cenbank Statutory Trust III.

As of March 31, 2019, the Company had $21,000 of borrowing against its revolving line of credit with an unrelated commercial bank. The Company subsequently paid off such borrowings prior to the date of this report. There were no borrowings against the line as of December 31, 2018.

Note 6. Leases

On January 1, 2019, the Company adopted ASU 2016-02, Leases, as further explained in Note 1, Summary of Significant Accounting Policies. The Company’s primary leasing activities relate to certain real estate leases entered into in support of the Company’s branch operations and back office operations. Prior to the Guaranty acquisition, on January 1, 2019, the Company leased 18 of its 74 branches. With the Guaranty acquisition, the Company increased its branch network by 32 branches, of which six are operated under lease agreements. The Company’s branch locations operated under lease agreements have all been designated as operating leases. In addition, the Company leases certain equipment under operating leases. The Company does not have leases designated as finance leases.

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-

use (“ROU”) assets and operating lease liabilities in the consolidated balance sheets. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease pre-payments made and excludes lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which the Company has elected to account for separately as the non-lease component amounts are readily determinable under most leases.

As of March 31, 2019 the Company’s lease ROU assets and related lease liabilities were $37,202 and $32,741, respectively, and have remaining terms ranging from 1 to 32 years, including extension options that the Company is reasonably certain will be exercised.

The table below summarizes our net lease cost:



	Three months ended March 31, 2019
Operating lease cost	$	1,892
Variable lease cost	494
Sublease income	(57		)

Note 7. Commitments and Contingencies

Financial Instruments with Off-Balance Sheet Risk

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. The commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheet.

The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of this instrument. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. At March 31, 2019 and December 31, 2018, the approximate amounts of these financial instruments were as follows:



	March 31,		December 31,
	2019		2018
Commitments to extend credit	$	2,367,735	$	1,761,724
Standby letters of credit	25,045		14,997
	$	2,392,780	$	1,776,721

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company upon extension of credit is based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, farm crops, property, plant and equipment and income-producing commercial properties.

(Dollars in thousands, except for share and per share information)

Letters of credit are written conditional commitments used by the Company to guarantee the performance of a customer to a third party. The Company’s policies generally require that letter of credit arrangements contain security and debt covenants similar to those contained in loan arrangements. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount shown in the table above. If the commitment is funded, the Company would be entitled to seek recovery from the customer. As of March 31, 2019 and December 31, 2018, no amounts have been recorded as liabilities for the Company’s potential obligations under these guarantees.

Litigation

The Company is involved in certain legal actions arising from normal business activities. Management believes that the outcome of such proceedings will not materially affect the financial position, results of operations or cash flows of the Company. A legal proceeding that the Company believes could become material is described below.

Independent Bank is a party to a legal proceeding inherited by Independent Bank in connection with its acquisition of BOH Holdings, Inc. and its subsidiary, Bank of Houston (BOH). The plaintiffs in the case are alleging that Independent Bank aided and abetted or participated in a fraudulent scheme. Independent Bank is pursuing insurance coverage for these claims, including reimbursement for defense costs. The Company believes the claims made in this lawsuit are without merit and is vigorously defending the lawsuit. The Company is unable to predict when the matter will be resolved, the ultimate outcome or potential costs or damages to be incurred. Please see Part II, Item 1. for more details on this lawsuit.

Note 8. Income Taxes

Income tax expense for the three months ended March 31, 2019 and 2018 was as follows:



	Three months ended March 31,
	2019			2018
Income tax expense for the period	$	11,126		$	6,805
Effective tax rate	23.1		%	19.0		%

The effective tax rates for 2019 and 2018 differ from the statutory federal tax rate of 21% largely due to tax exempt interest income earned on certain investment securities and loans, the nontaxable earnings on bank owned life insurance, excess tax benefits on restricted stock vestings, nondeductible compensation, and acquisition related expenses.

Note 9. Fair Value Measurements

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

The Company elected the fair value option for certain residential mortgage loans held for sale originated after July 1, 2018 in accordance with Accounting Standard Codification (ASC) 825, Financial Instruments. This election allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging. The Company has not elected the fair value option for other residential mortgage loans held for sale primarily because they are not economically hedged using derivative instruments. See below and Note 10, Derivative Financial Instruments, for additional information.

There were no transfers between level categorizations and no changes in valuation methodologies for the periods presented.

A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.

Securities classified as available for sale are reported at fair value utilizing Level 1 and Level 2 inputs. Securities are classified within Level 1 when quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. For securities utilizing Level 2 inputs, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury and other yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things.

Certain mortgage loans held for sale are measured at fair value on a recurring basis due to the Company's election to adopt fair value accounting treatment for those loans originated after July 1, 2018 for which the Company has entered into certain derivative financial instruments as part of its mortgage banking and related risk management activities. These instruments include interest rate lock commitments and mandatory forward commitments to sell these loans to investors known as forward mortgage-backed securities trades. This election allows for a more effective offset of the changes in fair values of the assets and the mortgage related derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging. Mortgage loans held for sale, for which the fair value option was elected, which are sold on a servicing released basis, are valued using a market approach by utilizing either: (i) the fair value of securities backed by similar mortgage loans, adjusted for certain factors to approximate the fair value of a whole mortgage loan, including the value attributable to mortgage servicing and credit risk, (ii) current commitments to purchase loans or (iii) recent observable market trades for similar loans, adjusted to credit risk and other individual loan characteristics. As these prices are derived from market observable inputs, the Company classifies these valuations as Level 2 in the fair value disclosures. For mortgage loans held for sale for which the fair value option was elected, the earned current contractual interest payment is recognized in interest income, loan origination costs and fees on fair value option loans are recognized in earnings as incurred and not deferred. The Company has no continuing involvement in any residential mortgage loans sold.

The estimated fair values of interest rate lock commitments utilize current secondary market prices for underlying loans and estimated servicing value with similar coupons, maturity and credit quality, subject to the anticipated loan funding probability (pull-through rate). The fair value of interest rate lock commitments is subject to change primarily due to changes in interest rates and the estimated pull-through rate. These commitments are classified as Level 2 in the fair value disclosures, as the valuations are based on observable market inputs.

Forward mortgage-backed securities trades are exchange-traded or traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilized the exchange price or dealer market price for the particular derivative contract; therefore these contracts are classified as Level 2. The estimated fair values are subject to change primarily due to changes in interest rates.

The Company also enters into certain interest rate derivative positions that are not designated as hedging instruments. The estimated fair value of these commercial loan interest rate swaps are obtained from a pricing service that provides the swaps' unwind value (Level 2 inputs). See Note 10, Derivative Financial Instruments, for more information.

Assets and Liabilities Measured on a Nonrecurring Basis

In accordance with ASC Topic 820, certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following table presents the assets carried on the consolidated balance sheet by caption and by level in the fair value hierarchy at March 31, 2019 and December 31, 2018, for which a nonrecurring change in fair value has been recorded:



			Fair Value Measurements at Reporting Date Using
	Assets Measured at Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Period Ended Total Losses
March 31, 2019
Assets:
Impaired loans	$	2,300	$	—	$	—	$	2,300	$	690
Other real estate	1,564		—		—		1,564		436

December 31, 2018
Assets:
Impaired loans	$	3,824	$	—	$	—	$	3,824	$	2,227

Impaired loans (loans which are not expected to repay all principal and interest amounts due in accordance with the original contractual terms) are measured at an observable market price (if available) or at the fair value of the loan’s collateral (if collateral dependent). Fair value of the loan’s collateral is determined by appraisals or independent valuation, which is then adjusted for the estimated costs related to liquidation of the collateral. Management’s ongoing review of appraisal information may result in additional discounts or adjustments to valuation based upon more recent market sales activity or more current appraisal information derived from properties of similar type and/or locale. Therefore, the Company has categorized its impaired loans as Level 3.

Other real estate is measured at fair value on a nonrecurring basis (upon initial recognition or subsequent impairment). Other real estate is classified within Level 3 of the valuation hierarchy. When transferred from the loan portfolio, other real estate is adjusted to fair value less estimated selling costs and is subsequently carried at the lower of carrying value or fair value less estimated selling costs. The fair value is determined using an external appraisal process, discounted based on internal criteria. Therefore, the Company has categorized its other real estate as Level 3.

In addition, mortgage loans held for sale not recorded under the fair value option are required to be measured at the lower of cost or fair value. The fair value of these loans is based upon binding quotes or bids from third party investors. As of March 31, 2019 and December 31, 2018, all mortgage loans held for sale not recorded under the fair value option were recorded at cost.

The methods and assumptions used by the Company in estimating fair values of financial instruments as disclosed herein in accordance with ASC Topic 825, Financial Instruments, as amended by ASU 2016-01 requiring public entities to use the exit price notion effective January 1, 2018, other than for those measured at fair value on a recurring and nonrecurring basis discussed above, are as follows:

Cash and cash equivalents: The carrying amounts of cash and cash equivalents approximate their fair value.

Certificates of deposit held in other banks: The fair value of certificates of deposit held in other banks is based upon current market rates.

Loans held for sale, at cost: The fair value of loans held for sale is determined based upon commitments on hand from investors.

Loans: A discounted cash flow model is used to estimate the fair value of the loans. The discounted cash flow approach models the credit losses directly in the projected cash flows, applying various assumptions regarding credit, interest and prepayment risks for the loans based on loan types, payment types and fixed or variable classifications.

Federal Home Loan Bank of Dallas and other restricted stock: The carrying value of restricted securities such as stock in the Federal Home Loan Bank of Dallas and Independent Bankers Financial Corporation approximates fair value.

Deposits: The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is their carrying amounts). The carrying amounts of variable-rate certificates of deposit (CDs) approximate their fair values at the reporting date. Fair values for fixed-rate CDs are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Federal Home Loan Bank advances, line of credit and federal funds purchased: The fair value of advances maturing within 90 days approximates carrying value. Fair value of other advances is based on the Company’s current borrowing rate for similar arrangements.

Other borrowings: The carrying value of repurchase agreements approximates fair value due to the short term nature. The fair value of private subordinated debentures are based upon prevailing rates on similar debt in the market place. The subordinated debentures that are publicly traded are valued based on indicative bid prices based upon market pricing observations in the current market.

Junior subordinated debentures: The fair value of junior subordinated debentures is estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements.

Accrued interest: The carrying amounts of accrued interest approximate their fair values.

Off-balance sheet instruments: Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties' credit standing. The fair value of commitments is not material.

Note 10. Derivative Financial Instruments

The Company enters into certain derivative financial instruments as part of its hedging strategy. These financial instruments are not designated as hedging instruments and are used for asset and liability management related to the Company's mortgage banking activities and commercial customers' financing needs. All derivatives are carried at fair value in either other assets or other liabilities.

Through the normal course of business, the Company enters into interest rate lock commitments with consumers to originate mortgage loans at a specified interest rate. These commitments, which contain fixed expiration dates, offer the borrower an interest rate guarantee provided the loan meets underwriting guidelines and closes within the timeframe established by the Company.

During July 2018, the Company began managing the changes in fair value associated with changes in interest rates related to interest rate lock commitments by using forward sold commitments known as forward mortgage-backed securities trades. These instruments are typically entered into at the time the interest rate lock commitment is made.

The Company also offers certain derivatives products, primarily interest rate swaps, directly to qualified commercial banking customers to facilitate their risk management strategies. The interest rate swap derivative positions relate to transactions in which the Company enters into an interest rate swap with a customer, while at the same time entering into an offsetting interest rate swap with another financial institution. An interest rate swap transaction allows customers to effectively convert a variable rate loan to a fixed rate. In connection with each swap, the Company agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, the Company agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. These products were not significant for disclosure in prior periods.

The following table provides the outstanding notional balances and fair values of outstanding derivative positions at March 31, 2019 and December 31, 2018:



	Outstanding Notional Balance		Asset Derivative Fair Value		Liability Derivative Fair Value
March 31, 2019
Interest rate lock commitments	$	33,097	$	1,252	$	—
Forward mortgage-backed securities trades	32,750		—		217
Commercial loan interest rate swaps:
Loan customer counterparty	119,741		2,342		128
Financial institution counterparty	119,741		127		2,506

December 31, 2018
Interest rate lock commitments	$	20,306	$	822	$	—
Forward mortgage-backed securities trades	27,500		—		226
Commercial loan interest rate swaps:
Loan customer counterparty	25,055		360		108
Financial institution counterparty	25,055		109		406

The credit exposure related to interest rate swaps is limited to the net favorable value of all swaps by each counterparty, which was approximately $2,342 at March 31, 2019.

The initial and subsequent changes in the fair value of interest rate lock commitments and the forward sales of mortgage-back securities are recorded in mortgage banking revenue. These gains and losses were not attributable to instrument-specific credit risk. For interest rate swaps, because the Company acts as an intermediary for our customer, changes in the fair value of the underlying derivative contracts substantially offset each other and do not have a material impact on the results of operations.

Income for the three months ended March 31, 2019 was as follows:

Note 11. Stock Awards and Stock Warrants

The Company grants common stock awards to certain employees of the Company. In connection with the Company's initial public offering in April 2013, the Board of Directors adopted the 2013 Equity Incentive Plan. Under this plan, the Compensation Committee may grant awards to certain employees of the Company in the form of restricted stock, restricted stock rights, restricted stock units, qualified and nonqualified stock options, performance-based share awards and other equity-based awards. All stock awards issued under expired plans prior to 2013 are fully vested. In May 2018, the shareholders of the Company voted to amend the plan to increase the reserved shares of common stock to be awarded by the Company’s compensation committee by 1,500,000 for a total of 2,300,000 reserved shares. As of March 31, 2019, there were 1,469,857 shares remaining available for grant for future awards. The shares currently issued under the 2013 Plan are restricted stock awards and will vest evenly over the required employment period, generally ranging from three to five years. Shares granted under the 2013 Equity Incentive Plan were issued at the date of grant and receive dividends.

In connection with the acquisition of Guaranty, as further described in Note 13, Business Combinations, unvested awards of restricted Guaranty common stock granted under Guaranty’s 2015 Long-Term Incentive Plan (Guaranty 2015 RSA), as amended, that were outstanding as of January 1, 2019, the acquisition date, were converted into awards of restricted shares of Independent common stock (Replacement RSA) with the same terms and conditions as were applicable under such Guaranty 2015 RSA, except with respect to any performance-vesting Guaranty 2015 RSA, which became a service-vesting RSA only. The Replacement RSA will vest over the remaining service period, generally in two years, and do not receive dividends.

The following table summarizes the activity in nonvested shares for the three months ended March 31, 2019 and 2018:



	Number of Shares		Weighted Average Grant Date Fair Value
Nonvested shares, December 31, 2018	252,903		$	62.81

Compensation expense related to these awards is recorded based on the fair value of the award at the date of grant and totaled $2,172 and $1,412 for the three months ended March 31, 2019 and 2018, respectively. Compensation expense is recorded in salaries and employee benefits in the accompanying consolidated statements of income. At March 31, 2019, future compensation expense is estimated to be $16,043 and will be recognized over a remaining weighted average period of 2.88 years.

The fair value of common stock awards that vested during the three months ended March 31, 2019 and 2018 was $4,542 and $3,617, respectively. The Company recorded $20 and $349 in excess tax benefits on vested restricted stock to income tax expense for the three months ended March 31, 2019 and 2018, respectively.

There were no modifications of stock agreements during the three months ended March 31, 2019 and 2018 that resulted in significant additional incremental compensation costs.

At March 31, 2019, the future vesting schedule of the nonvested shares is as follows:



First year		146,479
Second year		106,646

Note 12. Regulatory Matters

Under banking law, there are legal restrictions limiting the amount of dividends the Bank can declare. Approval of the regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels. For state banks, subject to regulatory capital requirements, payment of dividends is generally allowed to the extent of net profits.

The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Tier 2 capital for the Company includes permissible portions of the Company's subordinated notes. The permissible portion of qualified subordinated notes decreases 20% per year during the final five years of the term of the notes.

The Company is subject to the Basel III regulatory capital framework (the "Basel III Capital Rules"). The implementation of the capital conservation buffer was effective for the Company on January 1, 2016 at the 0.625% level and was phased in over a four-year period increasing by 0.625% each year, until it reached 2.5% on January 1, 2019. The capital conservation buffer is designed to absorb losses during periods of economic stress and requires increased capital levels for the purpose of capital distributions and other payments. Failure to meet the full amount of the buffer will result in restrictions on the Company's ability to make capital distributions, including dividend payments and stock repurchases and to pay discretionary bonuses to executive officers.

(Dollars in thousands, except for share and per share information)

Fully phased in on January 1, 2019, the Basel III Capital Rules require the Company and Bank to maintain (i) a minimum ratio of Common Equity Tier 1 ("CET1") capital to risk-weighted assets of at least 4.5%, plus the 2.5% capital conservation buffer (7.0%), (ii) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the 2.5% capital conservation buffer (8.5%), (iii) a minimum ratio of Total capital (that is, Tier 1 plus Tier 2) to risk-weighted assets of at least 8.0%, plus the 2.5% capital conservation buffer (10.5%) and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average quarterly assets.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total, CET1 and Tier 1 capital (as defined in the regulations) to risk weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of March 31, 2019 and December 31, 2018, the Company and the Bank meet all capital adequacy requirements to which they are subject, including the capital buffer requirement.

As of March 31, 2019 and December 31, 2018, the Bank’s capital ratios exceeded those levels necessary to be categorized as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized," the Bank must maintain minimum total risk based, CET1, Tier 1 risk based and Tier 1 leverage ratios as set forth in the table. There are no conditions or events that management believes have changed the Bank’s category.

As a result of the acquisition, the Company added 32 full service branch locations along the Colorado Front Range, including locations throughout the Denver metropolitan area and along I-25 to Fort Collins expanding the Company's footprint in Colorado. The Company issued 13,179,748 shares of Company stock for the outstanding shares of Guaranty common stock, including restricted stock replacement awards.

The Company has recognized a provisional amount of goodwill of $270,583 which is calculated as the excess of both the consideration exchanged and liabilities assumed compared to the estimated fair market value of identifiable assets acquired. The goodwill in this acquisition resulted from a combination of expected synergies and expansion into desirable Colorado markets. None of the goodwill recognized is expected to be deductible for income tax purposes.

Overview

This Management’s Discussion and Analysis of Financial Condition and Results of Operations analyzes the major elements of the Company’s financial condition and results of operation as reflected in the interim consolidated financial statements and accompanying notes appearing in this Quarterly Report on Form 10-Q. This section should be read in conjunction with the Company’s interim consolidated financial statements and accompanying notes included elsewhere in this report and with the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2018.

The Company was organized as a bank holding company in 2002. On January 1, 2009, the Company was merged with Independent Bank Group Central Texas, Inc., and, since that time, has pursued a strategy to create long-term shareholder value through organic growth of our community banking franchise in our market areas and through selective acquisitions of complementary banking institutions with operations in our market areas. On April 8, 2013, the Company consummated the initial public offering, or IPO, of its common stock which is traded on the Nasdaq Global Select Market.

As of March 31, 2019, the Company operated 106 full service banking locations in north, central and southeast Texas regions, and along the Colorado Front Range region. During the first quarter of 2019, the Company announced its intent to rebalance its retail footprint by consolidating branches in Texas and Colorado. This consolidation will result in the reduction of eight branches in Colorado and four branches in Texas with the majority of branch closures occurring in second quarter 2019. In April 2019, the Company also announced its plan to sell another branch in the North Texas region, which is expected to close in third quarter 2019. As a result of the planned branch reduction, Independent Bank will have a total of 93 branches, with 61 Texas locations and 32 Colorado locations.

The Company’s headquarters are located at 1600 Redbud, Suite 400, McKinney, Texas 75069, and its telephone number is (972) 562-9004. The Company’s website address is www.ibtx.com. Information contained on the Company’s website is not incorporated by reference into this Quarterly Report on Form 10-Q and is not part of this or any other report.

Our principal business is lending to and accepting deposits from businesses, professionals and individuals. We conduct all of our banking operations through Independent Bank, which is a Texas state banking corporation and our principal subsidiary (the Bank). We derive our income principally from interest earned on loans and, to a lesser extent, income from securities available for sale. We also derive income from non-interest sources, such as fees received in connection with various deposit services, mortgage banking operations and investment advisory services. From time to time, we also realize gains on the sale of assets. Our principal expenses include interest expense on interest-bearing customer deposits, advances from the Federal Home Loan Bank of Dallas (FHLB) and other borrowings, operating expenses such as salaries, employee benefits, occupancy costs, data processing and communication costs, expenses associated with other real estate owned, other administrative expenses, provisions for loan losses and our assessment for FDIC deposit insurance.

Certain Events Affect Year-over-Year Comparability

Acquisitions. The Company completed the acquisition of Guaranty Bancorp, a Colorado corporation and its subsidiary, Guaranty Bank and Trust Company (Guaranty), on January 1, 2019. As a result of the acquisition, the Company added 32 full service banking locations along the Colorado Front Range including locations throughout the Denver metropolitan area and along I-25 to Fort Collins, expanding the Company's footprint in Colorado. This acquisition increased total assets by $3.9 billion, gross loans by $2.8 billion and deposits by $3.1 billion.

The Company completed the acquisition of Integrity Bancshares, Inc., a Texas corporation and its subsidiary, Integrity Bank, SSB, Houston, Texas (Integrity), a Texas state savings bank on June 1, 2018. The Company acquired four new locations as part of the transaction, representing an expansion in the Houston metropolitan area. This acquisition increased total assets by $851.9 million, gross loans by $651.8 million and deposits by $593.1 million.

The comparability of the Company's results of operations for the three months ended March 31, 2019 and 2018 are affected by these acquisitions.

Discussion and Analysis of Results of Operations for the Three Months Ended March 31, 2019 and 2018

The following discussion and analysis of our results of operations compares the operations for the three months ended March 31, 2019 with the three months ended March 31, 2018. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results of operations that may be expected for all of the year ending December 31, 2019.

Results of Operations

For the three months ended March 31, 2019, net income was $37.1 million ($0.85 per common share on a diluted basis) compared with net income of $29.0 million ($1.02 per common share on a diluted basis) for the three months ended March 31, 2018. The Company posted annualized returns on average equity of 6.78% and 8.72%, returns on average assets of 1.08% and 1.35% and efficiency ratios of 60.37% and 52.30% for the three months ended March 31, 2019 and 2018, respectively. The efficiency ratio is calculated by dividing total noninterest expense (which excludes the provision for loan losses and the amortization of other intangible assets) by net interest income plus noninterest income.

Net Interest Income

The Company’s net interest income is its interest income, net of interest expenses. Changes in the balances of the Company’s earning assets and its deposits, FHLB advances and other borrowings, as well as changes in the market interest rates, affect the Company’s net interest income. The difference between the Company’s average yield on earning assets and its average rate paid for interest-bearing liabilities is its net interest spread. Noninterest-bearing sources of funds, such as demand deposits and stockholders’ equity, also support the Company’s earning assets. The impact of the noninterest-bearing sources of funds is reflected in the Company’s net interest margin, which is calculated as annualized net interest income divided by average earning assets.

Net interest income was $121.7 million for the three months ended March 31, 2019, an increase of $47.7 million, or 64.5%, from $74.0 million for the three months ended March 31, 2018. This increase is due primarily to a $4.7 billion increase, or 62.7%, in average interest earning assets to $12.2 billion for the three months ended March 31, 2019 compared to $7.5 billion for the three months ended March 31, 2018. The increase is primarily due to $3.4 billion in interest-earning assets acquired in the Guaranty transaction as well as $718.9 million of interest-earning assets acquired in the Integrity transaction as well as organic growth over the year. The average yield on interest earning assets increased 40 basis points from 4.77% for the three months ended March 31, 2018 to 5.17% for the three months ended March 31, 2019. The increase from the prior year is due primarily to higher rates on interest-earning assets due to continued increases in the Fed Funds rate for the year over year period as well as an increase in acquired loan accretion due to the Guaranty transaction. The average cost of interest-bearing liabilities increased 54 basis points to 1.59% for the three months ended March 31, 2019 compared to 1.05% for the three months ended March 31, 2018. The increase is primarily due to higher rates offered on our deposits, primarily commercial money market accounts and certificates of deposit, resulting from both market competition and the increased interest rates on deposit products tied to Fed Funds rates, as well as rate increases on short-term FHLB advances and junior subordinated debt. The aforementioned changes resulted in a five basis point increase in the net interest margin for the three months ended March 31, 2019 at 4.05% compared to 4.00% for the three months ended March 31, 2018.

Provision for Loan Losses

Management actively monitors the Company’s asset quality and provides specific loss provisions when necessary. Provisions for loan losses are charged to income to bring the total allowance for loan losses to a level deemed appropriate by management based on such factors as historical loss experience, trends in classified loans and past dues, the volume, concentrations and growth in the loan portfolio, current economic conditions and the value of collateral.

Loans are charged off against the allowance for loan losses when appropriate. Although management believes it uses the best information available to make determinations with respect to the provision for loan losses, future adjustments may be necessary if economic conditions differ from the assumptions used in making the determination.

The Company recorded a $3.2 million provision for loan losses for the three months ended March 31, 2019 compared to $2.7 million for the comparable period in 2018. Provision expense is primarily reflective of organic loan growth as well as charge-offs or specific reserves taken during the respective period. Net charge-offs were $1.5 million and $137 thousand for the three months ended March 31, 2019 and 2018, respectively. The increase in net charge-offs for the three months ended March 31, 2019 was primarily related to $402 thousand in nonaccrual charge-offs in addition to a partial charge-off of an energy loan totaling $827 thousand which had been fully reserved in prior periods.

Noninterest Income

The following table sets forth the components of noninterest income for the three months ended March 31, 2019 and 2018 and the period-over-period variations in such categories of noninterest income:

Total noninterest income increased $7.0 million, or 73.7% for the three months ended March 31, 2019 over same period in 2018. Significant changes in the components of noninterest income are discussed below.

Service charges on deposit accounts. Service charges on deposit accounts increased $2.4 million, or 69.6% for the three months ended March 31, 2019, as compared to the same period in 2018. The increase in service charge income reflects an increase in deposit accounts primarily due to the acquisition of Guaranty Bancorp in January 2019 as well as the acquisition of Integrity in June 2018.

Investment management and trust. The investment management subsidiary and trust division were acquired in the Guaranty transaction on January 1, 2019.

Increase in cash surrender value of BOLI. The increase in cash surrender value of BOLI increased $620 thousand, or 83.9% for the three months ended March 31, 2019, as compared to the same period in 2018. The increase is primarily a result of $81 million in BOLI contracts acquired in the Guaranty transaction.

Table of Contents

Other. Other noninterest income increased $1.6 million, or 80.4% for the three months ended March 31, 2019 as compared to the same period in 2018. The increase from prior year is primarily due to the additional accounts acquired in the Guaranty transaction as well as an increase in acquired loan recoveries during first quarter 2019.

Noninterest Expense

Noninterest expense increased $41.6 million, or 92.6% for the three months ended March 31, 2019 as compared to the same period in 2018.

Salaries and employee benefits. Salary and employee benefits increased $17.2 million, or 68.4% for the three months ended March 31, 2019 compared to the same period in 2018. Salary and employee benefit expenses increased for the comparative three months due to additional headcount related to both the Guaranty and Integrity acquisitions as well as organic growth during the year. Salaries and benefits expense is also elevated due to severance and retention payments made or accrued totaling $3.2 million related primarily to the Guaranty transaction and our announced branch restructuring in second quarter 2019, as well as the Company's increase in the 401(k) contribution match in third quarter 2018.

Occupancy. Occupancy expense increased $3.3 million, or 58.7% for the three months ended March 31, 2019 compared to the same period in 2018. The increase is primarily reflective of 32 additional branches acquired in the Guaranty transaction and four branches acquired in the Integrity transaction.

Data processing. Data processing expense increased $1.4 million, or 56.7% three months ended March 31, 2019 compared to the same period in 2018. Data processing increased for the comparative three months primarily due to additional branches and accounts acquired with the Guaranty and Integrity acquisitions.

FDIC assessment. FDIC assessment expense increased $507 thousand, or 68.4% for the three months ended March 31, 2019 compared to the same period in 2018. The increases in FDIC assessment expense is due to additional accounts acquired with the Guaranty and Integrity acquisitions.

Amortization of other intangible assets. Intangible amortization increased $1.9 million, or 143.1% for the three months ended March 31, 2019 compared to the same period in 2018. The increase relates to the additional amortization of core deposit and customer intangibles related to the acquisition of Guaranty and Integrity transactions.

Table of Contents

Acquisition expenses. Acquisition expenses increased $14.4 million for the three months ended March 31, 2019 compared to the same period in 2018. The increase in acquisition expenses in the first quarter 2019 was primarily due to $8.7 million in change in control payments to Guaranty executives as well as an increase in professional fees, contract termination fees, and conversion-related expenses related to Guaranty.

Other noninterest expense. Other noninterest expense increased $1.9 million, or 28.8% for the three months ended March 31, 2019 compared to the same period in 2018. The increase in noninterest expense primarily reflects the additional headcount, branch locations and accounts acquired in the Guaranty and Integrity transactions but also due in part to higher deposit and loan-related expenses for the year over year period.

Income Tax Expense

Income tax expense was $11.1 million for the three months ended March 31, 2019 and $6.8 million for the same period in 2018. The effective tax rates were 23.1% for the three months ended March 31, 2019 compared to 19.0% for the same period in 2018. The higher effective tax rate in first quarter 2019 was due to $1.4 million in deductibility limitations related to the change in control payments made to Guaranty employees and $203 thousand in nondeductible expenses.

⁽¹⁾ Includes mortgage warehouse purchase loans of $251.3 million and $170.3 million at March 31, 2019 and December 31, 2018, respectively.

⁽²⁾Includes mortgage loans held for sale as of March 31, 2019 and December 31, 2018 of $22.6 million and $32.7 million respectively.

Our loan portfolio is the largest category of our earning assets. As of March 31, 2019 and December 31, 2018, total loans, net of allowance for loan losses and deferred fees, totaled $10.9 billion and $7.9 billion, respectively, which is an increase of 38.7% between the two dates. The increase is primarily due to $2.8 billion in loans acquired in the Guaranty but also due to organic loan growth during 2019.

Asset Quality

Nonperforming Assets. The Company has established procedures to assist the Company in maintaining the overall quality of the Company’s loan portfolio. In addition, the Company has adopted underwriting guidelines to be followed by the Company’s lending officers and require significant senior management review of proposed extensions of credit exceeding certain thresholds. When delinquencies exist, the Company rigorously monitors the levels of such delinquencies for any negative or adverse trends. The Company’s loan review procedures include approval of lending policies and underwriting guidelines by Independent Bank’s board of directors, an annual independent loan review, approval of large credit relationships by Independent Bank’s Executive Loan Committee and loan quality documentation procedures. The Company, like other financial institutions, is subject to the risk that its loan portfolio will be subject to increasing pressures from deteriorating borrower credit due to general economic conditions.

The Company discontinues accruing interest on a loan when management of the Company believes, after considering the Company’s collection efforts and other factors, that the borrower’s financial condition is such that collection of interest of that loan is doubtful. Loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans, including troubled debt restructurings, that are placed on nonaccrual status or charged off is reversed against interest income. Cash collections on nonaccrual loans are generally credited to the loan receivable balance, and no interest income is recognized on those loans until the principal balance has been collected. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Real estate the Company has acquired as a result of foreclosure or by deed-in-lieu-of foreclosure is classified as other real estate owned until sold. The Company's policy is to initially record other real estate owned at fair value less estimated costs to sell at the date of foreclosure. After foreclosure, other real estate is carried at the lower of the initial carrying amount (fair value less estimated costs to sell or lease), or at the value determined by subsequent appraisals or internal valuations of the other real estate.

The Company periodically modifies loans to extend the term or make other concessions to help a borrower with a deteriorating financial condition stay current on their loan and to avoid foreclosure. The Company generally does not forgive principal or interest on loans or modify the interest rates on loans to rates that are below market rates. Under applicable accounting standards, such loan modifications are generally classified as troubled debt restructurings.

Table of Contents

The following table sets forth the allocation of the Company’s nonperforming assets among the Company’s different asset categories as of the dates indicated. The Company classifies nonperforming loans (excluding loans acquired with deteriorated credit quality) as nonaccrual loans, loans past due 90 days or more and still accruing interest or loans modified under restructurings as a result of the borrower experiencing financial difficulties. The balances of nonperforming loans reflect the net investment in these assets, including deductions for purchase discounts.

⁽¹⁾	Nonaccrual loans include troubled debt restructurings of $496 thousand and $506 thousand at March 31, 2019 and December 31, 2018, respectively and excludes loans acquired with deteriorated credit quality of $8.9 million and $7.0 million as of March 31, 2019 and December 31, 2018, respectively.


⁽²⁾	Excluding mortgage warehouse purchase loans of $251.3 million and $170.3 million as of March 31, 2019 and December 31, 2018, respectively.

Nonaccrual loans decreased to $10.0 million at March 31, 2019 from $11.9 million as of December 31, 2018. Troubled debt restructurings that were not on nonaccrual status totaled $672 thousand at March 31, 2019 decreasing slightly from $687 thousand at December 31, 2018. The decrease in nonaccrual loans was primarily due to payoffs of two nonaccrual single-family interim construction loans and one commercial real estate loan totaling $3.9 million, nonaccrual charge-offs totaling $402 thousand, and a $544 thousand nonaccrual residential real estate loan placed in foreclosure, offset by a $3.0 million commercial loan placed on nonaccrual status during the three months ended March 31, 2019. The net increase in other real estate owned and repossessed assets is primarily due to the addition of three properties totaling $1.7 million as a result of the Guaranty acquisition as well as the addition noted above, off-set by a $436 thousand impairment.

As of March 31, 2019, the Company had a total of 137 substandard and doubtful loans with an aggregate principal balance of $61.6 million that were not currently impaired loans, nonaccrual loans, 90 days past due loans or troubled debt restructurings, but where the Company had information about possible credit problems of the borrowers that caused the Company’s management to have serious concerns as to the ability of the borrowers to comply with present loan repayment terms and that could result in those loans becoming nonaccrual loans, 90 days past due loans or troubled debt restructurings in the future.

Table of Contents

The Company generally continues to use the classification of acquired loans classified nonaccrual or 90 days and accruing as of the acquisition date. The Company does not classify acquired loans as troubled debt restructurings, or TDRs, unless the Company modifies an acquired loan subsequent to acquisition that meets the TDR criteria. Reported delinquency of the Company’s purchased loan portfolio is based upon the contractual terms of the loans.

Allowance for Loan Losses. The allowance for loan losses is established through charges to earnings in the form of a provision for loan losses. The Company’s allowance for loan losses represents the Company’s estimate of probable and reasonably estimable loan losses inherent in loans held for investment as of the respective balance sheet date. The Company’s methodology for assessing the adequacy of the allowance for loan losses includes a general allowance for performing loans, which are grouped based on similar characteristics, and an allocated allowance for individual impaired loans. Actual credit losses or recoveries are charged or credited directly to the allowance. As of March 31, 2019, the allowance for loan losses amounted to $46.5 million, or 0.43% of total loans held for investment, excluding mortgage warehouse purchase loans, compared with $44.8 million, or 0.58% as of December 31, 2018. The dollar increase from year end is primarily due to additional general reserves for organic loan growth. The decrease in the allowance for loan losses as a percentage of loans reflects that loans acquired in the Guaranty transaction were recorded at fair value without an allowance at acquisition date. As of March 31, 2019, the discount on acquired loans totaled $142.8 million.

The allowance for loan losses to nonperforming loans has increased from 354.73% at December 31, 2018 to 433.82% at March 31, 2019, due to an increase in the recorded allowance balance as well as a reduction in total nonperforming loans as noted above. Nonperforming loans have decreased to $10.7 million at March 31, 2019 compared to $12.6 million at December 31, 2018.

Securities Available for Sale

The Company’s investment strategy aims to maximize earnings while maintaining liquidity in securities with minimal credit, interest rate and duration risk. The types and maturities of securities purchased are primarily based on the Company’s current and projected liquidity and interest rate sensitivity positions.

The Company recognized a net gain of $245 thousand on the sale of securities for the three months ended March 31, 2019 and a net loss of $224 thousand on the sale of securities for the three month ended March 31, 2018. Securities represented 7.6% and 7.0% of the Company’s total assets at March 31, 2019 and December 31, 2018, respectively.

Management evaluates securities for other-than-temporary impairment (OTTI) on at least a quarterly basis and more frequently when economic or market conditions warrant such an evaluation. Management does not intend to sell any debt securities it holds and believes the Company more likely than not will not be required to sell any debt securities it holds before their anticipated recovery, at which time the Company will receive full value for the securities. Management has the ability and intent to hold the securities classified as available for sale that were in a loss position as of March 31, 2019 for a period of time sufficient for an entire recovery of the cost basis of the securities. For those securities that are impaired, the unrealized losses are largely due to interest rate changes. The fair value is expected to recover as the securities approach their maturity date. Management believes any impairment in the Company’s securities at March 31, 2019, is temporary and no other-than-temporary impairment has been realized in the Company’s consolidated financial statements.

Capital Resources and Regulatory Capital Requirements

Total stockholder’s equity was $2.2 billion at March 31, 2019 compared with $1.6 billion at December 31, 2018, an increase of approximately $627.8 million. The increase was primarily due to stock issued in the Guaranty acquisition for a total, net of offering costs, of $601.1 million as well as net income of $37.1 million earned by the Company during the three months ended March 31, 2019, stock based compensation of $2.2 million, and an increase of $11.8 million in unrealized gain (loss) on available for sale securities offset by a cumulative adjustment for change in accounting principles of $926 thousand, stock repurchased by the Company totaling $12.5 million and dividends paid of $10.9 million.

Share Repurchase Program. The Company established share repurchase programs in prior years which would allow the Company to purchase its common stock in the open market or in privately negotiated transactions. In general, share repurchase programs allow the Company to proactively manage its capital position and return excess capital to shareholders. On October 24, 2018, the Company announced the reestablishment of its share repurchase program. The program authorizes the purchase by the Company of up to $75,000 of its common stock. The repurchase program is authorized to continue through October 1, 2019. As of March 31, 2019, the Company repurchased a total of 172,738 shares of Company stock at a total cost of $10,000 under this program.

Liquidity Management

The Company continuously monitors the Company’s liquidity position to ensure that assets and liabilities are managed in a manner that will meet all of the Company’s short-term and long-term cash requirements. The Company manages the Company’s liquidity position to meet the daily cash flow needs of customers, while maintaining an appropriate balance between assets and liabilities to meet the return on investment objectives of the Company’s shareholders. The Company also monitors its liquidity requirements in light of interest rate trends, changes in the economy and the scheduled maturity and interest rate sensitivity of the investment and loan portfolios and deposits.

Liquidity risk management is an important element in the Company’s asset/liability management process. The Company’s short-term and long-term liquidity requirements are primarily to fund on-going operations, including payment of interest on deposits and debt, extensions of credit to borrowers, capital expenditures and shareholder dividends. These liquidity requirements are met primarily through cash flow from operations, redeployment of pre-paid and maturing balances in the Company’s loan and investment portfolios, debt financing and increases in customer deposits. The Company’s liquidity position is supported by management of liquid assets and liabilities and access to alternative sources of funds. Liquid assets include cash, interest-bearing deposits in banks, federal funds sold, securities available for sale and maturing or prepaying balances in the Company’s investment and loan portfolios. Liquid liabilities include core deposits, brokered deposits, federal funds purchased, securities sold under repurchase agreements and other borrowings. Other sources of liquidity include the sale of loans, the ability to acquire additional national market non core deposits, the issuance of additional collateralized borrowings such as FHLB advances, the issuance of debt securities, borrowings through the Federal Reserve’s discount window and the issuance of equity securities. For additional information regarding the Company’s operating, investing and financing cash flows, see the Consolidated Statements of Cash Flows provided in the Company’s consolidated financial statements.

In addition to the liquidity provided by the sources described above, the Company maintains correspondent relationships with other banks in order to sell loans or purchase overnight funds should additional liquidity be needed. As of March 31, 2019, the Company had established federal funds lines of credit with 11 unaffiliated banks totaling $425 million with no borrowings against the lines at that time. The Company also participates in an exchange that provides direct overnight borrowings with other financial institutions with a borrowing capacity of $279 million and none outstanding as of March 31, 2019. The Company has an unsecured line of credit totaling $100 million with an unrelated commercial bank. The line had $21.0 million outstanding as of March 31, 2019 and was subsequently paid off prior to the date of this report. Based on the values of stock, securities, and loans pledged as collateral, as of March 31, 2019, the Company had additional borrowing capacity with the FHLB of $2.0 billion. In addition, the Company maintains a secured line of credit with the Federal Reserve Bank with an availability to borrow $982.2 million.

Contractual Obligations

In the ordinary course of the Company’s operations, the Company enters into certain contractual obligations, such as obligations for operating leases and other arrangements with respect to deposit liabilities, FHLB advances and other borrowed funds. The Company believes that it will be able to meet its contractual obligations as they come due through the maintenance of adequate cash levels. The Company expects to maintain adequate cash levels through profitability, loan and securities repayment and maturity activity and continued deposit gathering activities. The Company has in place various borrowing mechanisms for both short-term and long-term liquidity needs.

On January 18, 2018, the Company entered into an agreement with an independent contractor for the oversight and construction of the Company's new corporate headquarters office building in McKinney, Texas. The 165,000 square foot building is estimated to cost approximately $58.0 million and expected to be completed in second quarter 2019. At March 31, 2019, the project's estimated remaining costs was approximately $22 million.

As a result of the acquisition of Guaranty completed during the three months ended March 31, 2019, the Company acquired deposit accounts, FHLB advances, subordinated debt commitments, junior subordinated debentures and assumed the operating lease commitments for several branch locations acquired in the Guaranty transaction.

Other than normal changes in the ordinary course of business and the items mentioned above, there have been no significant changes in the types of contractual obligations or amounts due since December 31, 2018.

Off-Balance Sheet Arrangements

In the normal course of business, the Company enters into various transactions, which, in accordance with accounting principles generally accepted in the United States, are not included in the Company’s consolidated balance sheets. However, the Company has only limited off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on the Company’s financial condition, revenues, expenses, results of operations, liquidity, capital expenditures or capital resources. Independent Bank enters into these transactions to meet the financing needs of the Company’s customers. These transactions include commitments to extend credit and issue standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets.

Commitments to Extend Credit. Independent Bank enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of Independent Bank’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding. Independent Bank minimizes its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures.

Standby Letters of Credit. Standby letters of credit are written conditional commitments that Independent Bank issues to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, Independent Bank would be required to fund the commitment. The maximum potential amount of future payments Independent Bank could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, the customer is obligated to reimburse Independent Bank for the amount paid under this standby letter of credit.

Independent Bank’s commitments to extend credit and outstanding standby letters of credit were $2.4 billion and $25.0 million, respectively, as of March 31, 2019. Since commitments associated with letters of credit and commitments to extend credit may expire unused, the amounts shown do not necessarily reflect the actual future cash funding requirements. The Company manages the Company’s liquidity in light of the aggregate amounts of commitments to extend credit and outstanding standby letters of credit in effect from time to time to ensure that the Company will have adequate sources of liquidity to fund such commitments and honor drafts under such letters of credit.

Critical Accounting Policies and Estimates

The preparation of the Company’s consolidated financial statements in accordance with U.S. generally accepted accounting principles, or GAAP, requires the Company to make estimates and judgments that affect the Company’s reported amounts of assets, liabilities, income and expenses and related disclosure of contingent assets and liabilities. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under current circumstances, results of which form the basis for making judgments about the carrying value of certain assets and liabilities that are not readily available from other sources. The Company evaluates the Company’s estimates on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions.

Accounting policies, as described in detail in the notes to the Company’s consolidated financial statements, are an integral part of the Company’s financial statements. A thorough understanding of these accounting policies is essential when reviewing the Company’s reported results of operations and the Company’s financial position. The Company believes that the critical accounting policies and estimates discussed below require the Company to make difficult, subjective or complex judgments about matters that are inherently uncertain. Changes in these estimates, that are likely to occur from period to period, or the use of different estimates that the Company could have reasonably used in the current period, would have a material impact on the Company’s financial position, results of operations or liquidity.

Acquired Loans. The Company’s accounting policies require that the Company evaluates all acquired loans for evidence of deterioration in credit quality since origination and to evaluate whether it is probable that the Company will collect all contractually required payments from the borrower.

Acquired loans from the transactions accounted for as a business combination include both loans with evidence of credit deterioration since their origination date and performing loans. The Company accounts for performing loans under ASC Paragraph 310-20, Nonrefundable Fees and Other Costs, with the related difference in the initial fair value and unpaid principal balance (the discount) recognized as interest income on a level yield basis over the life of the loan. The Company accounts for the nonperforming loans acquired in accordance with ASC Paragraph 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. At the date of the acquisition, acquired loans are recorded at their fair value with no valuation allowance.

For purchase credit impaired loans, the Company recognizes the difference between the undiscounted cash flows the Company expects (at the time the Company acquires the loan) to be collected and the investment in the loan, or the “accretable yield,” as interest income using the interest method over the life of the loan. The Company does not recognize contractually required payments for interest and principal that exceed undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” as a yield adjustment, loss accrual or valuation allowance. Increases in the expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over the loan’s remaining life, while decreases in expected cash flows are recognized as impairment. Valuation allowances on these impaired loans reflect only losses incurred after the acquisition.

Upon an acquisition, the Company generally continues to use the classification of acquired loans classified nonaccrual or 90 days and accruing. The Company does not classify acquired loans as TDRs unless the Company modifies an acquired loan subsequent to acquisition that meets the TDR criteria. Reported delinquency of the Company’s purchased loan portfolio is based upon the contractual terms of the loans.

Allowance for Loan Losses. The allowance for loan losses represents management’s estimate of probable and reasonably estimable credit losses inherent in the loan portfolio. In determining the allowance, the Company estimates losses on individual impaired loans, or groups of loans which are not impaired, where the probable loss can be identified and reasonably estimated. On a quarterly basis, the Company assesses the risk inherent in the Company’s loan portfolio based on qualitative and quantitative trends in the portfolio, including the internal risk classification of loans, historical loss rates, changes in the nature and volume of the loan portfolio, industry or borrower concentrations, delinquency trends, detailed reviews of significant loans with identified weaknesses and the impacts of local, regional and national economic factors on the quality of the loan portfolio. Based on this analysis, the Company records a provision for loan losses in order to maintain the allowance at appropriate levels.

Table of Contents

Determining the amount of the allowance is considered a critical accounting estimate, as it requires significant judgment and the use of subjective measurements, including management’s assessment of overall portfolio quality. The Company maintains the allowance at an amount the Company believes is sufficient to provide for estimated losses inherent in the Company’s loan portfolio at each balance sheet date, and fluctuations in the provision for loan losses may result from management’s assessment of the adequacy of the allowance. Changes in these estimates and assumptions are possible and may have a material impact on the Company’s allowance, and therefore the Company’s financial position, liquidity or results of operations.

Goodwill and Other Intangible Assets. The excess purchase price over the fair value of net assets from acquisitions, or goodwill, is evaluated for impairment at least annually and on an interim basis if an event or circumstance indicates that it is likely an impairment has occurred. The Company first assesses qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing a two step impairment test is unnecessary. If the Company concludes otherwise, then it is required to perform the first step of the two step impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit. The Company performs its impairment test annually as of December 31. There have been no circumstances since December 31, 2018 that would indicate any impairment has occurred, therefore, management does not believe goodwill is impaired as of March 31, 2019.

Core deposit intangibles and other acquired customer relationship intangibles lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Other intangible assets are being amortized on a straight-line basis over their estimated useful lives ranging from ten to thirteen years. Other intangible assets are tested for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.

The principal objective of the Company’s asset and liability management function is to evaluate the interest rate risk within the balance sheet and pursue a controlled assumption of interest rate risk while maximizing net income and preserving adequate levels of liquidity and capital. The Investment Committee of the Bank’s Board of Directors has oversight of Independent Bank's asset and liability management function, which is managed by the Company's Treasurer. The Treasurer meets with our Chief Financial Officer and senior executive management team regularly to review, among other things, the sensitivity of the Company’s assets and liabilities to market interest rate changes, local and national market conditions and market interest rates. That group also reviews the liquidity, capital, deposit mix, loan mix and investment positions of the Company.

The Company's management and the Board of Directors are responsible for managing interest rate risk and employing risk management policies that monitor and limit the Company's exposure to interest rate risk. Interest rate risk is measured using net interest income simulations and market value of portfolio equity analyses. These analyses use various assumptions, including the nature and timing of interest rate changes, yield curve shape, prepayments on loans, securities and deposits, deposit decay rates, pricing decisions on loans and deposits, reinvestment and replacement of asset and liability cash flows.

Instantaneous parallel rate shift scenarios are modeled and utilized to evaluate risk and establish exposure limits for acceptable changes in net interest margin. These scenarios, known as rate shocks, simulate an instantaneous change in interest rates and use various assumptions, including, but not limited to, prepayments on loans and securities, deposit decay rates, pricing decisions on loans and deposits, reinvestment and replacement of asset and liability cash flows.

The Company also analyzes the economic value of equity as a secondary measure of interest rate risk. This is a complementary measure to net interest income where the calculated value is the result of the market value of assets less the market value of liabilities. The economic value of equity is a longer term view of interest rate risk because it measures the present value of the future cash flows. The impact of changes in interest rates on this calculation is analyzed for the risk to the Company's future earnings and is used in conjunction with the analyses on net interest income.

The Company conducts periodic analyses of its sensitivity to interest rate risks through the use of a third-party proprietary interest-rate sensitivity model. That model has been customized to the Company's specifications. The analyses conducted by use of that model are based on current information regarding the Company's actual interest-earnings assets, interest-bearing liabilities, capital and other financial information that it supplies. The third party uses that information in the model to estimate the Company's sensitivity to interest rate risk.

The Company's interest rate risk model indicated that it was in a balanced rate sensitive position in terms of interest rate sensitivity as of March 31, 2019. The table below illustrates the impact of an immediate and sustained 200 and 100 basis point increase and a 100 basis point decrease in interest rates on net interest income based on the interest rate risk model as of March 31, 2019:



Hypothetical Shift in Interest Rates (in bps)	% Change in Projected Net Interest Income
200	1.27%
100	0.73
(100)	0.70

These are good faith estimates and assume that the composition of the Company's interest sensitive assets and liabilities existing at each period-end and is based on future maturities and market pricing over the relevant twelve month measurement period and that changes in market interest rates are instantaneous and sustained across the yield curve regardless of duration of pricing characteristics of specific assets or liabilities. Also, this analysis does not contemplate any actions that the Company might undertake in response to changes in market interest rates. The Company believes these estimates are not necessarily indicative of what actually could occur in the event of immediate interest rate increases or decreases of this magnitude. As interest-bearing assets and liabilities re-price in different time frames and proportions to market interest rate movements, various assumptions must be made based on historical relationships of these variables in reaching any conclusion. Since these correlations are based on competitive and market conditions, the Company anticipates that our future results will likely be different from the foregoing estimates, and such differences could be material.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures. An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q was performed under the supervision and with the participation of management, including its Chief Executive Officer and Chief Financial Officer. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures are effective to provide reasonable assurance that information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure and are effective to provide reasonable assurance that such information is recorded, processed, summarized and reported within the time periods specified by the SEC's rules and forms.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Changes in internal control over financial reporting. There were no changes in the Company’s internal control over financial reporting during the three months ended March 31, 2019 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II

Item 1. LEGAL PROCEEDINGS

In the normal course of business, the Company and Independent Bank are named as defendants in various lawsuits. Management of the Company and Independent Bank, following consultation with legal counsel, do not expect the ultimate disposition of any, or a combination, of these matters to have a material adverse effect on the business of the Company or Independent Bank. A legal proceeding that the Company believes could become material is described below.

Independent Bank is a party to a legal proceeding inherited by Independent Bank in connection with the Company's acquisition of BOH Holdings, Inc. and its subsidiary, Bank of Houston, or BOH, that was completed on April 15, 2014. Several entities related to R. A. Stanford, or the Stanford Entities, including Stanford International Bank, Ltd., or SIBL, had deposit accounts at BOH. Certain individuals who had purchased certificates of deposit from SIBL filed a class action lawsuit against several banks, including BOH, on November 11, 2009 in the U.S. District Court Northern District of Texas, Dallas Division, in a case styled Peggy Roif Rotstain, et al. on behalf of themselves and all others similarly situated, v. Trustmark National Bank, et al., Civil Action No. 3:09-CV-02384-N-BG. The suit alleges, among other things, that the plaintiffs were victims of fraud by SIBL and other Stanford Entities and seeks to recover damages and alleged fraudulent transfers by the defendant banks.

On May 1, 2015, the plaintiffs filed a motion requesting permission to file a Second Amended Class Action Complaint in this case, which motion was subsequently granted. The Second Amended Class Action Complaint asserted previously unasserted claims, including aiding and abetting or participation in a fraudulent scheme based upon the large amount of deposits that the Stanford Entities held at BOH and the alleged knowledge of certain BOH officers. The plaintiffs seek recovery from Independent Bank and other defendants for their losses. The case was inactive due to a court-ordered discovery stay issued March 2, 2015 pending the Court’s ruling on plaintiff’s motion for class certification and designation of class representatives and counsel. On November 7, 2017, the Court issued an order denying the plaintiff’s motion. In addition, the Court lifted the previously ordered discovery stay. On January 11, 2018, the Court entered a scheduling order providing that the case be ready for trial on January 27, 2020. However, discovery in this case has been extended and the Company now expects that the trial will be delayed until sometime after May 2020. The Company has experienced an increase in legal fees associated with the defense of this claim and anticipates further increases in legal fees as the case proceeds to trial.

Independent Bank notified its insurance carriers of the claims made in the Second Amended Complaint. The insurance carriers have initially indicated that the claims are not covered by the policies or that a “loss” has not yet occurred. Independent Bank pursued insurance coverage as well as reimbursement of defense costs through the initiation of litigation and other means. On November 6, 2018, the Company settled claims under its Financial Institutions Select Policy pursuant to which the Company received payment of an amount which is not material to the operations of the Company. The Company did not settle any claims under its Financial Institution Bond Policy.

Table of Contents

Independent Bank believes that the claims made in this lawsuit are without merit and is vigorously defending this lawsuit. This is complex litigation involving a number of procedural matters and issues. As such, Independent Bank is unable to predict when this matter may be resolved and, given the uncertainty of litigation, the ultimate outcome of, or potential costs or damages arising from, this case.
