CONDENSED NOTES TO UNAUDITED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

(Dollars in thousands, except per share data)

Note 1 - Basis of Financial Statement Presentation

The accompanying consolidated interim financial statements of LegacyTexas Financial Group, Inc. (the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles ("US GAAP") and with the rules and regulations of the Securities and Exchange Commission for interim financial reporting. Accordingly, they do not include all of the information and footnotes required for complete financial statements. In the opinion of management, all normal and recurring adjustments which are considered necessary to fairly present the results for the interim periods presented have been included. Certain items in prior periods were reclassified to conform to the current presentation. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 (“2016 Form 10-K”). Interim results are not necessarily indicative of results for a full year.

In preparing the financial statements, management is required to make estimates and assumptions that affect the recorded amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the period. Actual results could differ from those estimates. For further information with respect to significant accounting policies followed by the Company in preparation of its consolidated financial statements, refer to the 2016 Form 10-K.

The accompanying Unaudited Consolidated Interim Financial Statements include the accounts of the Company, whose business primarily consists of the operations of its wholly owned subsidiary, LegacyTexas Bank (the “Bank”). All significant intercompany transactions and balances are eliminated in consolidation.

Note 2 - Earnings Per Common Share

Basic earnings per common share is computed by dividing net income (which has been adjusted for distributed and undistributed earnings to participating securities) by the weighted-average number of common shares outstanding for the period, reduced for average unallocated ESOP shares and average unvested restricted stock awards. Unvested restricted stock awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method described in Accounting Standards Codification ("ASC") 260-10-45-60B. Diluted earnings per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock (such as stock awards and options) were exercised or converted to common stock, or resulted in the issuance of common stock that then shared in the Company’s earnings. Diluted earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding for the period increased for the dilutive effect of unexercised stock options and unvested restricted stock awards. The dilutive effect of the unexercised stock options and unvested restricted stock awards is calculated under the treasury stock method utilizing the average market value of the Company’s stock for the period. A reconciliation of the numerator and denominator of the basic and diluted earnings per common share computation for the three and nine months endedSeptember 30, 2017 and 2016 is as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,

Other-than-Temporary Impairment

In determining other-than-temporary impairment for debt securities, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than amortized cost; (2) the financial condition and near-term prospects of the issuer; (3) whether the market decline was affected by macroeconomic conditions; and (4) whether the Company has the intent and ability to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.

As of September 30, 2017, 191 securities had unrealized losses, 63 of which had been in an unrealized loss position for over 12 months at September 30, 2017. The Company does not believe these unrealized losses are other-than-temporary and, at September 30, 2017, believes that full recovery of the amortized cost basis is more likely than not. All principal and interest payments are being received on time and in full.

The allowance for loan losses and related provision expense are susceptible to change if the credit quality of our loan portfolio changes, which is evidenced by many factors, including but not limited to charge-offs and non-performing loan trends. Generally, consumer real estate lending has a lower credit risk profile compared to other consumer lending (such as automobile loans). Commercial real estate and commercial and industrial lending, however, can have higher risk profiles than consumer loans due to these loans being larger in amount and non-homogeneous in structure and term. Changes in economic conditions, the mix and size of the loan portfolio and individual borrower conditions can dramatically impact our level of allowance for loan losses in relatively short periods of time.

The allowance for loan losses is maintained to cover incurred losses that are estimated in accordance with US GAAP. It is our estimate of credit losses inherent in our loan portfolio at each balance sheet date. Our methodology for analyzing the allowance for loan losses consists of general and specific components. For the general component, we stratify the loan portfolio into homogeneous groups of loans that possess similar loss potential characteristics and apply a loss ratio to these groups of loans to estimate the credit losses in the loan portfolio. We use both historical loss ratios and qualitative loss factors assigned to major loan collateral types to establish general component loss allocations, inclusive of estimated loss emergence periods. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data and external economic indicators, which are not yet reflected in the historical loss ratios, and that could impact the Company's specific loan portfolios. The Allowance for Loan Loss Committee sets and adjusts qualitative loss factors by regularly reviewing changes in underlying loan composition and the seasonality of specific portfolios. The Allowance for Loan Loss Committee also considers credit quality and trends relating to delinquency, non-performing and adversely rated loans within the Company's loan portfolio when evaluating qualitative loss factors. Additionally, the Allowance for Loan Loss Committee adjusts qualitative factors to account for the potential impact of external economic factors, including the unemployment rate, vacancy and capitalization rates and other pertinent economic data specific to our primary market area and lending portfolios.

For the specific component, the allowance for loan losses includes loans where management has concerns about the borrower's ability to repay and on individually analyzed loans found to be impaired. Management evaluates current information and events regarding a borrower's ability to repay its obligations and considers a loan to be impaired when the ultimate collectability of amounts due, according to the contractual terms of the loan agreement, is in doubt. If an impaired loan is collateral-dependent,

(Dollars in thousands, except per share data)

the fair value of the collateral, less the estimated cost to sell, is used to determine the amount of impairment. If an impaired loan is not collateral-dependent, estimated discounted cash flows are used to determine the amount of impairment, if any. For impaired loans, the amount of the impairment can be adjusted, based on current data, until such time as the actual basis is established by acquisition of the collateral or until the basis is collected. Impairment losses are reflected in the allowance for loan losses through a charge to the provision for credit losses. Subsequent recoveries are credited to the allowance for loan losses. Cash receipts for accruing loans are applied to principal and interest under the contractual terms of the loan agreement. Cash receipts on impaired loans for which the accrual of interest has been discontinued are applied first to principal.

Large groups of smaller-balance homogeneous loans are collectively evaluated for impairment. As a result, the Company does not separately identify consumer real estate loans less than $417 or individual consumer non-real estate secured loans for impairment disclosures. The Company considers these loans to be homogeneous in nature due to the smaller dollar amount and the similar underwriting criteria.

Changes in the allowance for off-balance sheet credit losses on lending-related commitments and guarantees on credit card debt, included in "accrued expenses and other liabilities" on the consolidated balance sheets, are summarized in the following table. Please see Note 9 - Commitments and Contingent Liabilities for more information.

Past due status is based on the contractual terms of the loan. Loans that are past due 30 days are considered delinquent. Interest income on loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Non-mortgage consumer loans are typically charged off no later than 120 days past due. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans include both smaller balance homogeneous loans that are collectively evaluated for impairment and larger individually classified impaired loans.

All interest accrued but not received for loans placed on nonaccrual status is reversed against interest income. Subsequent receipts on non-accrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

No loans past due over 90 days were still accruing interest at September 30, 2017. At December 31, 2016, $141 of loans past due over 90 days were still accruing interest, which consisted entirely of PCI loans. At September 30, 2017, no PCI loans were considered non-performing loans. No Warehouse Purchase Program loans were non-performing at September 30, 2017 or December 31, 2016.

A loan that has been modified is considered a troubled debt restructuring (“TDR”) when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. Modifications to loan terms may include a modification of the contractual interest rate to a below-market rate (even if the modified rate is higher than the original rate), forgiveness of accrued interest, forgiveness of a portion of principal, an extended repayment period or a deed in lieu of foreclosure or other transfer of assets other than cash to fully or partially satisfy a debt. The Company's policy is to place all TDRs on nonaccrual for a minimum period of six months. Loans qualify for return to accrual status once they have demonstrated performance with the restructured terms of the loan agreement for a minimum of six months and the collection of principal and interest under the revised terms is deemed probable. All TDRs are considered to be impaired loans.

The outstanding balances of TDRs are shown below:

For loans collateralized by real property and commercial and industrial loans, credit exposure is monitored by internally assigned grades used for classification of loans. A loan is considered “special mention” when management has determined that there is a potential weakness that deserves management's close attention. Loans rated as "special mention" are not adversely classified according to regulatory classifications and do not expose the Company to sufficient risk to warrant adverse classification. A loan is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or the collateral pledged, if any. “Substandard” loans include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected, and the loan may or may not meet the criteria for impairment. Loans classified as “doubtful” have all of the weaknesses of those classified as “substandard” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions and values, “highly questionable and improbable.” All other loans that do not fall into the above mentioned categories are considered “pass” loans. Updates to internally assigned grades are made monthly and/or upon significant developments.

For other consumer loans (non-real estate), credit exposure is monitored by payment history of the loans. Non-performing other consumer loans are on nonaccrual status and are generally greater than 90 days past due.

Note 5 - Fair Value

ASC 820, “Fair Value Measurements and Disclosures”, establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3: Prices or valuation techniques that require inputs that are both significant and unobservable in the market. These instruments are valued using the best information available, some of which is internally developed, and reflects a reporting entity’s own assumptions about the risk premiums that market participants would generally require and the assumptions they would use.

Assets and Liabilities Measured on a Recurring Basis

Assets and liabilities measured at fair value on a recurring basis are summarized below.

¹  At September 30, 2017, loans held for sale had an aggregate outstanding principal balance of $25,115. There were no mortgage loans held for sale that were 90 days or greater past due or on non-accrual at September 30, 2017.

The following methodologies were used to measure the fair value of financial assets and liabilities valued on a recurring basis:

Securities available for sale - The fair values of securities available for sale are determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities' relationship to other benchmark quoted securities (Level 2 inputs).

22

LEGACYTEXAS FINANCIAL GROUP, INC.

CONDENSED NOTES TO UNAUDITED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

(Dollars in thousands, except per share data)

Residential mortgage loans held for sale - Mortgage loans held for sale, 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. Interest income on mortgage loans held for sale is recognized based on the contractual rates and reflected in interest income on loans held for sale in the consolidated income statement. The Company has no continuing involvement in any residential mortgage loans sold.

Derivative instruments:

Interest rate lock commitments ("IRLCs") - The estimated fair values of IRLCs 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 IRLCs 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 - These 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.

Loan customer counterparty and financial institution counterparty - 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). Please see Note 6 — Derivative Financial Instruments for more information.

Assets and Liabilities Measured on a Non-Recurring Basis

Assets measured at fair value on a non-recurring basis are summarized below. There were no liabilities measured at fair value on a non-recurring basis at September 30, 2017 or December 31, 2016.

	Fair Value Measurements Using Level 3

Commercial real estate	10,544		10,638
Construction and land	1,756		194
Residential real estate	91		—
Foreclosed assets- other	1,194		6

Impaired loans that are collateral dependent are measured for impairment using the fair value of the collateral adjusted by additional Level 3 inputs, such as discounts of market value, estimated marketing costs and estimated legal expenses. Impaired loans secured by real estate, receivables or inventory had discounts determined by management on an individual loan basis. Impaired loans that are not collateral dependent are measured for impairment by a discounted cash flow analysis using a net present value calculation that utilizes data from the loan file before and after the modification.

Foreclosed assets are measured at the lower of book or fair value less costs to sell using third party appraisals, listing agreements or sale contracts, which may be adjusted by additional Level 3 inputs, such as discounts of market value, estimated marketing costs and estimated legal expenses. Management may also consider additional adjustments on specific properties due to the age of the appraisal, expected holding period, lack of comparable sales, or if the other real estate owned is a special use property. At September 30, 2017, the Company had $43 in residential mortgage loans in the process of foreclosure.

The Credit Risk Management department evaluates the valuations on impaired loans and foreclosed assets at least quarterly. The valuations on impaired loans are reviewed at least quarterly by the Allowance for Loan Loss Committee and are considered

in the calculation of the allowance for loan losses. Unobservable inputs, such as discounts to collateral, are monitored and adjusted if market conditions change.

The following methods and assumptions were used to estimate the fair values of each class of financial instrument presented:

Cash and cash equivalents - Due to their short term nature, the carrying amount approximates the estimated fair value.

Securities held to maturity - The fair values of these securities is determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities' relationship to other benchmark quoted securities (Level 2 inputs).

24

LEGACYTEXAS FINANCIAL GROUP, INC.

(Dollars in thousands, except per share data)

Loans held for investment (including Warehouse Purchase Program loans) - Fair value is based on discounted cash flows using current market offering rates, estimated life, and applicable credit risk.

FHLB stock and other restricted securities - The fair value on these securities is their cost basis due to restrictions on transferability.

Accrued interest receivable - Due to their short term nature, the carrying amount approximates the estimated fair value.

Deposits - Fair value is calculated using the FHLB advance curve to discount cash flows based on the estimated life of the deposits.

FHLB advances - Fair value is calculated using the FHLB advance curve to discount cash flows based on the contractual repayment schedule.

Repurchase agreement - The fair value is based on discounting the estimated cash flows using the current rate at which similar borrowings would be made with similar terms and remaining maturities.

Subordinated debt - The estimated fair value is based on current market rates on similar debt in the market.

Accrued interest payable - Due to their short term nature, the carrying amount approximates the estimated fair value.

The fair value of off-balance sheet items is based on the current fees or costs that would be charged to enter into or terminate such arrangements and are not considered significant to this presentation.

These financial instruments are not designated as hedging instruments and are used for asset and liability management and commercial customers' financing needs. All derivatives are carried at fair value in either other assets or other liabilities.

IRLCs - In the normal course of business, the Company enters into IRLCs 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.

Forward mortgage-backed securities trades - The Company manages the changes in fair value associated with changes in interest rates related to IRLCs by using forward sold commitments known as forward mortgage-backed securities trades. These instruments are typically entered into at the time the IRLC is made.

Interest rate swaps and caps - These derivative positions relate to transactions in which we enter into an interest rate swap or cap with a customer, while at the same time entering into an offsetting interest rate swap or cap with another financial institution. An interest rate swap transaction allows our customer to effectively convert a variable rate loan to a fixed rate. In connection with each swap, we agree 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, we agree 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. In connection with each interest rate cap, we sell a cap to the customer and agree to pay interest if the underlying index exceeds the strike price defined in the cap agreement.  Simultaneously we purchase a cap with matching terms from another financial institution which agrees to pay us if the underlying index exceeds the strike price.

The commercial loan customer counterparty weighted average received and paid interest rates for interest rate swaps outstanding at September 30, 2017 and December 31, 2016 are presented in the following table.

	Weighted-Average Interest Rate
	September 30, 2017				December 31, 2016
	Received		Paid		Received		Paid
Loan customer counterparty	2.52	%	2.52	%	3.12	%	2.36	%

Our credit exposure on interest rate swaps is limited to the net favorable value of all swaps by each counterparty, which was approximately $151 at September 30, 2017 and $118 at December 31, 2016. This credit exposure is partly mitigated as transactions with customers are generally secured by the collateral, if any, securing the underlying transaction being hedged. Our credit exposure, net of collateral pledged, relating to interest rate swaps with upstream financial institution counter-parties was approximately $1,239 at September 30, 2017.  A credit support annex is in place and allows the bank to call collateral from upstream financial institution counter-parties. Collateral levels are monitored and adjusted on a regular basis for changes in

interest rate swap values. Our cash collateral pledged for interest rate swaps and included in our interest-bearing deposits, which totaled $1,950 at September 30, 2017 and $1,950 at December 31, 2016, is in excess of our credit exposure.

The initial and subsequent changes in the fair value of IRLCs and the forward sales of mortgage-back securities are recorded in net gain on sale of mortgage loans. These gains and losses were not attributable to instrument-specific credit risk. For interest rate swaps and caps, because we act 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 our results of operations. Income (loss) for the three and nine months endedSeptember 30, 2017 and 2016 was as follows:

Note 7 - Share-based Compensation

The 2017 Omnibus Incentive Plan (the "2017 Plan") was approved at the Company's 2017 annual meeting of shareholders, held on May 22, 2017. Prior to approval of the 2017 Plan by shareholders, the Company had in effect the 2012 and 2007 Equity Incentive Plans (the “Prior Plans” and together with the 2017 Plan, the “Plans”). No further awards will be made under the Prior Plans and shares reserved to make new awards under the Prior Plans have been released; however, shares reserved to fund issued and outstanding awards under the Prior Plans continue to be reserved to provide for those awards.  All awards outstanding under the Prior Plans remain outstanding in accordance with their terms.  Each outstanding award under the Prior Plans continue to be governed solely by the terms of the documents evidencing such award, and no provision of the 2017 Plan is deemed to affect or otherwise modify the rights or obligations of the holders of such awards with respect to their acquisition of Company shares. The 2017 Plan permits the granting of non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and cash awards to participants. Eligible participants under the 2017 Plan include employees and directors (including advisory and emeritus directors) of the Company and its subsidiaries. As of September 30, 2017, no shares had been issued under the 2017 Plan. There are 3,250,000 total shares authorized under the 2017 Plan, with a fungible share rate of 2.5-for-1 for full-value awards (stock-based awards other than stock options and stock appreciation rights.)

The Plans are accounted for under ASC 718, Compensation - Stock Compensation, which requires companies to record compensation cost for share-based payment transactions with employees in return for employment service. Compensation cost is recognized for stock options and restricted stock awards based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with time-based vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. For awards with performance-based vesting conditions, compensation cost is recognized when the achievement of the performance condition is considered probable of achievement. If a performance condition is subsequently determined to be improbable of achievement, compensation cost is reversed.

Compensation cost charged to income for share-based compensation is presented below:

¹  For restricted stock awards with time-based vesting conditions, the grant date fair value is based upon the closing stock price as quoted on the NASDAQ Stock Market on the grant date.

²  For restricted stock awards with performance-based vesting conditions, the value of the award is based upon the closing stock price as quoted on the NASDAQ Stock Market on the date of vesting. Until the final value is determined on the vesting date, the Company estimates the fair value based upon the closing stock price as quoted on the NASDAQ Stock Market near the last business day of each month.

As of September 30, 2017, there was $3,673 of total unrecognized compensation expense related to non-vested restricted shares awarded under the Company's Plans. That expense is expected to be recognized over a weighted-average period of 1.3 years. The total fair value of shares vested during the nine months endedSeptember 30, 2017 and 2016, was $2,819 and $2,615, respectively.

Under the terms of the 2017 Plan, stock options may not be granted with an exercise price less than the fair market value of the Company’s common stock on the date the option is granted and may not be exercised later than ten years after the grant date. The fair market value is the closing stock price as quoted on the NASDAQ Stock Market on the date of grant.

The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. The risk-free interest rate is the implied yield available on U.S. Treasury zero-coupon issues with a remaining term equal to the expected term of the stock option in effect at the time of the grant. The expected term of stock options is based on employees' actual vesting behavior and expected volatilities are based on historical volatilities of the Company’s common stock. Expected dividends are the estimated dividend rate over the expected term of the stock options.

The weighted average fair value of stock options granted during the nine months ended September 30, 2017 and 2016 was $10.74 and $7.76, respectively. The fair value of options granted was determined using the following weighted-average assumptions as of grant date:

	2017		2016
Expected stock price volatility	31.86	%	32.07	%
Expected dividends	1.61	%	1.93	%
Expected term of stock options (years)	6.2		6.3
Risk-free interest rate	2.18	%	1.37	%

As of September 30, 2017, there was $9,176 of total unrecognized compensation expense related to non-vested stock options. That expense is expected to be recognized over a weighted-average period of 2.2 years. At September 30, 2017, the Company applied an estimated forfeiture rate of 5% based on historical activity. The intrinsic value for stock options is calculated based on the difference between the exercise price of the underlying awards and the market price of our common stock as of the reporting date. The total intrinsic value of stock options exercised was $2,799 and $656 for the nine months ended September 30, 2017 and 2016, respectively.

Effective January 1, 2017, the Company changed the accounting for income taxes upon the vesting of stock options and restricted stock to be in accordance with ASC 718, as modified by Accounting Standards Update ("ASU") 2016-09, Improvements to Employee Share-Based Payment Accounting. Prior to the implementation of ASU 2016-09, the tax effects of income tax deductions in excess of compensation cost (windfalls) were recorded in additional paid-in capital, and the tax effects of compensation cost in excess of income tax deductions (shortfalls) were recorded in additional paid-in capital to the extent of previously recognized windfalls, with the remainder recorded in income tax expense. Under ASU 2016-09, all tax effects of windfalls and shortfalls related to share-based payments are recorded through the income statement.

For the nine months ended September 30, 2017, we recognized income tax deductions in excess of compensation cost of $3,734 for share-based payment awards, which resulted in a tax benefit of $1,307 recorded as a reduction of income tax expense. The tax effect of this windfall is treated as a discrete item in this interim reporting period and is not considered in determining the annual estimated effective tax rate. The classification of excess tax benefits on the statement of cash flows will be shown as an operating activity.

Note 9 - Commitments and Contingent Liabilities

In the normal course of business, the Company enters into various transactions which, in accordance with US GAAP, are not included in its consolidated balance sheets. The Company enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and standby letters of credit which involve, to varying degrees, elements of credit and interest rate risk. Credit losses up to the face amount of these instruments could occur, although material losses are not anticipated. The Company's credit policies applied to loan originations are also applied to these commitment requests, including obtaining collateral at the exercise of the commitment.

The contractual amounts of financial instruments with off‑balance sheet risk at September 30, 2017 and December 31, 2016, are summarized below. Please see Part I-Item 2-"Off-Balance Sheet Arrangements, Contractual Obligations and Commitments" of this Form 10-Q for information related to commitment maturities.

	September 30, 2017		December 31, 2016
Unused commitments to extend credit	$	1,853,334	$	1,642,528
Unused capacity on Warehouse Purchase Program loans	709,302		892,659
Standby letters of credit	28,649		29,198
Total unused commitments/capacity	$	2,591,285	$	2,564,385

Unused commitments to extend credit - The Company enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Since many commitments expire without being drawn upon, the total contractual amount of commitments does not necessarily represent future cash requirements of the Company. Substantially all of the Company's commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of future loan funding.

Unused capacity on Warehouse Purchase Program loans - In regard to unused capacity on Warehouse Purchase Program loans, the Company has established maximum purchase facility amounts, but reserves the right, at any time, to refuse to buy any mortgage loans offered for sale by each customer, for any reason in the Company's sole and absolute discretion.

Standby letters of credit - Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

In addition to the commitments above, the Company guarantees the credit card debt of certain customers to the merchant bank that issues the credit cards. These guarantees are in place for as long as the guaranteed credit card is open. At September 30, 2017 and December 31, 2016, these credit card guarantees totaled $5,116 and $3,335, respectively. This amount represents the maximum potential amount of future payments under the guarantee, which the Company is responsible for in the event of customer non-payment.

The Company funds an allowance for credit losses on off-balance sheet lending-related commitments and guarantees on credit card debt through a charge to provision for credit losses on the Company's consolidated statement of income. At September 30, 2017 and December 31, 2016, this allowance for credit losses on off-balance sheet lending-related commitments and guarantees on credit card debt, included in "other liabilities" on the Company's consolidated balance sheets, totaled $1,086 and $1,500, respectively.

In addition to the commitments above, the Company had overdraft protection available in the amounts of $85,004 and $85,709 at September 30, 2017 and December 31, 2016, respectively.

The Company, at September 30, 2017 and December 31, 2016, had FHLB letters of credit of $955,025 and $946,338, respectively, pledged to secure public deposits, repurchase agreements, and for other purposes required or permitted by law.

At September 30, 2017 and December 31, 2016, the Company had $1,680 and $2,080, respectively, of unfunded commitments recorded in other liabilities in its consolidated balance sheet related to investments in community development-oriented private equity funds used for Community Reinvestment Act purposes.

Note 10 - Recent Accounting Developments    

Effect of Newly Issued But Not Yet Effective Accounting Standards

In May 2014, the Financial Accounting Standards Board (the "FASB") issued ASU 2014-09, Revenue from Contracts with Customers. This ASU states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU affects entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which deferred the effective date of ASU 2014-09 for public entities to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Our revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. We have completed our initial evaluation of the impact of ASU 2014-09 on components of our non-interest income and have not found any significant changes to our methodology of recognizing revenue. In the fourth quarter of 2017, we will complete this evaluation and finalize disclosures that will be included in our 2018 financial statements, as required by ASU 2014-09, as we will adopt the standard in the first quarter of 2018 with a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be significant.

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurements of Financial Assets and Financial Liabilities. This ASU requires that all equity investments be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under the equity method of accounting or those that result in consolidation of the investee). This ASU also requires that an entity present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, this ASU eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. For public business entities, this ASU is effective for annual periods beginning after December 15, 2017, and interim periods therein. The adoption of this ASU is not expected to have a significant impact on the Company's financial statements and disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases. This ASU requires lessees to put most leases on their balance sheets but recognize expenses in the income statement in a manner similar to current accounting treatment. This ASU changes the guidance on sale-leaseback transactions, initial direct costs and lease execution costs, and, for lessors, modifies the classification criteria and the accounting for sales-type and direct financing leases. For public business entities, this ASU is effective for annual periods beginning after December 15, 2018, and interim periods therein. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is evaluating the impact of this ASU on its financial statements and disclosures.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. This ASU removes the thresholds that companies apply to measure credit losses on financial instruments measured at amortized cost, such as loans, receivables, and held-to-maturity debt securities. Under current US GAAP, companies generally recognize credit losses when it is probable that the loss has been incurred. This revised guidance will remove all recognition thresholds and will require companies to recognize an allowance for lifetime expected credit losses. Credit losses will be immediately recognized through net income; the amount recognized will be based on the current estimate of contractual cash flows not expected to be collected over the financial asset’s contractual term. ASU 2016-13 also amends the credit loss measurement guidance for available for sale debt securities. For public business entities, this ASU is effective for financial statements issued for fiscal years and for interim periods within those fiscal years beginning after December 15, 2019. The Company is evaluating the impact of this ASU on its financial statements and disclosures.

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. This ASU amends the hedge accounting model to enable entities to better portray their risk management activities in their financial statements, by expanding an entity's ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. This ASU eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Additionally, this ASU also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. For public business entities, this ASU is

effective for financial statements issued for fiscal years and for interim periods within those fiscal years beginning after December 15, 2018. The Company is evaluating the impact of this ASU on its financial statements and disclosures.

Business Strategies

Our principal business consists of attracting retail deposits from the general public and the business community and investing those funds, along with borrowed funds, in commercial real estate loans, secured and unsecured commercial and industrial loans, as well as permanent loans secured by first and second mortgages on one-to-four family residences and consumer loans. Additionally, the Warehouse Purchase Program allows mortgage banking company customers to close one-to four-family real estate loans in their own name and manage its cash flow needs until the loans are sold to investors. Our operating revenues are derived principally from interest earned on interest-earning assets, including loans and investment securities and service charges and fees on deposits and other account services. Our primary sources of funds are deposits, FHLB advances and other borrowings, and payments received on loans and securities. We offer a variety of deposit accounts that provide a wide range of interest rates and terms, generally including savings, money market, term certificate and demand accounts.

Our principal objective is to be an independent, commercially-oriented, customer-focused financial services company, providing outstanding service and innovative products in our primary market area of North Texas. Our Board of Directors has adopted a strategy designed to maintain growth and profitability, a strong capital position and high asset quality.

Performance Highlights

• Net income for the three months ended September 30, 2017 was $28.7 million, an increase of $1.5 million, or 5.5%, from net income of $27.2 million for the three months ended September 30, 2016. The increase in net income was driven by higher interest income on loans and non-interest income, partially offset by increased interest expense, provision for credit losses, and non-interest expense.

• Assets totaled $9.07 billion at September 30, 2017, which generated basic earnings per share for the third quarter of 2017 of $0.61.

• Gross loans held for investment at September 30, 2017, excluding Warehouse Purchase Program loans, grew $552.5 million from December 31, 2016, while total deposits grew $394.9 million for the same period.

• Warehouse Purchase Program loans totaled $1.13 billion at September 30, 2017, an increase of $72.6 million from December 31, 2016.

Critical Accounting Estimates

Certain of our accounting estimates are important to the portrayal of our financial condition, since they require management to make difficult, complex or subjective judgments, some of which may relate to matters that are inherently uncertain. Estimates are susceptible to material changes as a result of changes in facts and circumstances. Facts and circumstances which could affect these judgments include, but are not limited to, changes in interest rates, changes in the performance of the economy and changes in the financial condition of borrowers. Management believes that determining the allowance for loan losses is its most critical accounting estimate. Our accounting policies are discussed in detail in Note 1 of the Notes to Consolidated Financial Statements contained in Item 8 of our 2016 Form 10-K.

Allowance for Loan Loss. The allowance for loan losses and related provision expense are susceptible to change if the credit quality of our loan portfolio changes, which is evidenced by many factors, including but not limited to charge-offs and non-performing loan trends. Generally, consumer real estate lending has a lower risk profile compared to other consumer lending (such as automobile loans). Commercial real estate and commercial and industrial lending, however, can have higher risk profiles than consumer loans due to these loans being larger in amount and more susceptible to fluctuations in industry, market and economic conditions. While management uses available information to recognize losses on loans, changes in economic conditions, the mix and size of the loan portfolio and individual borrower conditions can dramatically impact our level of allowance for loan losses in relatively short periods of time. Management believes that the allowance for loan losses is

37

maintained at a level that represents coverage of our best estimate of credit losses in the loan portfolio as of September 30, 2017.

Management evaluates current information and events regarding a borrower's ability to repay its obligations and considers a loan to be impaired when the ultimate collectability of amounts due, according to the contractual terms of the loan agreement, is in doubt. If an impaired loan is collateral-dependent, the fair value of the collateral, less the estimated cost to sell, is used to determine the amount of impairment. If an impaired loan is not collateral-dependent, the impairment amount is determined using the negative difference, if any, between the estimated discounted cash flows and the loan amount due. For impaired loans, the amount of the impairment can be adjusted, based on current data, until such time as the actual basis is established by acquisition of the collateral or until the basis is collected. Impairment losses are reflected in the allowance for loan losses through a charge to the provision for credit losses. Subsequent recoveries are credited to the allowance for loan losses. Cash receipts for accruing loans are applied to principal and interest under the contractual terms of the loan agreement. Cash receipts on impaired loans for which the accrual of interest has been discontinued are applied first to principal.

Comparison of Financial Condition at September 30, 2017 and December 31, 2016

General. Total assets increased by $706.4 million, or 8.4%, to $9.07 billion at September 30, 2017 from $8.36 billion at December 31, 2016, primarily due to a $552.5 million, or 9.1%, increase in gross loans held for investment, excluding Warehouse Purchase Program loans, and a $72.6 million, or 6.9%, increase in Warehouse Purchase Program loans.

Loans. Gross loans held for investment increased by $625.1 million, or 8.8%, to $7.75 billion at September 30, 2017 from $7.12 billion at December 31, 2016, while loans held for sale increased by $4.7 million, or 22.0%, for the same period.

Gross loans	$	7,771,776	$	7,142,043	$	629,733		8.8	%

Gross loans held for investment at September 30, 2017, excluding Warehouse Purchase Program loans, grew $552.5 million, or 9.1%, from December 31, 2016, which included growth in the commercial real estate, commercial and industrial and consumer real estate loan portfolios and was partially offset by declines in the construction and land and other consumer loan portfolios. Commercial real estate and commercial and industrial loans at September 30, 2017 increased by $346.1 million and $103.5 million, respectively, from December 31, 2016. Consumer real estate loans at September 30, 2017 increased by $123.0 million, while construction and land and other consumer loans decreased by $12.4 million and $7.7 million, respectively, from December 31, 2016.

Reserve-based energy loans, which are reported as commercial and industrial loans, totaled $526.8 million at September 30, 2017, down $424,000 from $527.2 million at December 31, 2016. Substantially all of the reserve-based energy loans are secured by deeds of trust on properties containing proven oil and natural gas reserves.

At September 30, 2017, our reserve-based energy portfolio (reported above at $526.8 million) was secured by collateral that consisted of 53% crude oil reserves and 47% natural gas reserves. We encourage, and in some cases even require, borrowers to utilize commodity hedges, in order to stabilize cash flows during volatile commodity price environments.  Hedges are used to guard against falling prices, and the goal is that the duration of the hedge will last long enough for prices to come back from any significant decline.  Hedges will typically include minimum and maximum allowed percentage of production, a minimum and maximum allowed term, and a minimum price.

In addition to the reserve-based energy loans, the Bank has loans categorized as "Midstream and Other," which are typically related to the transmission of oil and natural gas and would only be indirectly impacted from declining commodity prices. At September 30, 2017, "Midstream and Other" loans had a total outstanding balance of $27.8 million, down $11.2 million from $39.0 million at December 31, 2016. Also, at September 30, 2017, we had four relationships in the commercial and industrial loan portfolio (aside from the reserve-based and midstream loans discussed above) that are involved in the energy exploration sector providing front-end service to companies who drill oil and gas wells and whose business could be impacted by the dramatic reduction in drilling activity as a result of a severe drop in the price of oil and gas.  These relationships totaled $1.2 million at September 30, 2017.

Warehouse Purchase Program loans increased by $72.6 million, or 6.9%, to $1.13 billion at September 30, 2017 from $1.06 billion at December 31, 2016. Although not bound by any legally binding commitment, when a purchase decision is made, the Bank purchases a 100% participation interest in the loans originated by our mortgage banking company customers.

39

The mortgage banking company closes mortgage loans consistent with underwriting standards established by approved investors and, once all pertinent documents are received, the participation interest is delivered by the Bank to the investor selected by the originator and approved by us. Loans funded by the Warehouse Purchase Program during the third quarter of 2017 consisted of 44% conforming, 48% government loans and 8% of other loan types, including Jumbo loans.

Allowance for Loan Losses. The allowance for loan losses is maintained to cover incurred losses that are estimated in accordance with US GAAP. It is our estimate of credit losses inherent in our loan portfolio at each balance sheet date. Our methodology for analyzing the allowance for loan losses consists of general and specific components. For more information about the Company's calculation of its allowance for loan losses, please see Item 1 (Financial Statements) - Note 4 - "Loans" under Part 1 of this report.

Acquired loans initially are recorded at fair value, which includes an estimate of credit losses expected to be realized over the remaining lives of the loans, and therefore no corresponding allowance for loan losses is recorded for these loans at acquisition. An allowance will be recorded in later periods if additional losses are subsequently anticipated. Methods utilized to estimate the required allowance for loan losses for acquired loans not deemed credit-impaired at acquisition are similar to originated loans; however, the estimate of loss is limited to the amount that the calculated allowance for loan losses exceeds the remaining purchase discount.

Purchased credit impaired ("PCI") loans are not considered nonperforming loans, and accordingly, are not included in the non-performing loans to total loans ratio as a numerator, but are included in total loans reflected in the denominator. The result is a downward trend in the ratio when compared to prior periods, assuming all other factors stay the same. Similarly, other asset quality ratios, such as the allowance for loan losses to total loans ratio will reflect a downward trend, assuming all other factors stay the same, due to the impact of PCI loans on the denominator with no corresponding impact in the numerator.

Our non-performing loans, which consist of nonaccrual loans, include both smaller balance homogeneous loans that are collectively evaluated for impairment and larger individually evaluated impaired loans. Loans generally are placed on nonaccrual status when the loan becomes 90 days or more delinquent. Non-performing loans include loans that are not contractually past due but have been placed on nonaccrual status due to the loan's designation as a troubled debt restructuring or if there is a distinct possibility that the Company will sustain some loss if deficiencies existing within a loan are not corrected. In all cases, loans are placed on nonaccrual status (or charged-off) at an earlier date when the collection of principal and/or interest becomes doubtful or other factors involving the loan warrant placing the loan on nonaccrual status.

Non-performing loans to total loans held for investment, excluding Warehouse Purchase Program loans, was 1.16% at September 30, 2017 compared to 1.84% at December 31, 2016. Including Warehouse Purchase Program loans, non-performing loans to total loans held for investment was 0.99% at September 30, 2017 compared to 1.56% at December 31, 2016. Non-performing loans decreased by $34.5 million to $76.9 million at September 30, 2017 from $111.4 million at December 31, 2016. During the third quarter of 2017, the Company recorded $11.9 million in charge-offs on the resolution of two reserve-based energy relationships. These relationships, which totaled $22.6 million prior to resolution, were rated as substandard and were non-performing; therefore, the resolution of these credits drove the $21.1 million decline in non-performing commercial and industrial loans compared to December 31, 2016. Additionally, non-performing construction and land loans declined by $11.4 million from December 31, 2016, due to the resolution of a relationship with a residential home builder. After various lots and homes were liquidated, paying down the credit facility, the Company foreclosed on the remaining partially completed homes in the 2017 period. For more information about the Company's non-performing loans, please see Note 4 of the Condensed Notes to Unaudited Consolidated Interim Financial Statements contained in Item 1 of this report.

Our allowance for loan losses was $70.0 million at September 30, 2017 compared to $64.6 million at December 31, 2016, or 0.90% of total loans held for investment (including Warehouse Purchase Program loans) at September 30, 2017 compared to 0.91% at December 31, 2016. Our allowance for loan losses to non-performing loans was 91.07% at September 30, 2017 compared to 57.97% at December 31, 2016. The increase in the allowance for loan losses from December 31, 2016 was primarily related to increased loan loss reserves allocated to the corporate healthcare finance portfolio, which is reported on the balance sheet as commercial and industrial loans and totaled $46.0 million at September 30, 2017. During the first quarter of 2017, the Company charged-off its $16.4 million interest in a large syndicated credit within the corporate healthcare finance portfolio. The note was sold at a deep discount after the borrower experienced liquidity constraints during the first quarter of 2017 that challenged its ongoing viability. One other relationship in the corporate healthcare finance portfolio totaling $7.8 million was considered to be impaired and rated as substandard (non-performing) at September 30, 2017. At this time, the Company is no longer originating corporate healthcare finance loans. Net charge-offs for the nine months ended September 30, 2017 totaled $30.7 million, an increase of $23.1 million from the nine months ended September 30, 2016, due to the corporate healthcare finance and energy charge-offs discussed above.

Classified Assets. Loans and other assets, such as securities and foreclosed assets, that are considered by management to be of lesser quality are classified as "substandard," "doubtful" or "loss." An asset is considered "substandard" if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. "Substandard" assets include those characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Assets classified as "doubtful" have all of the weaknesses of those classified as "substandard," with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Assets classified as "loss" are those considered uncollectible and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. PCI loans are included in the "substandard" and "doubtful" categories.

We regularly review the assets in our portfolio to determine whether any should be considered as classified. Total classified assets represented 14.7% of our total equity and 1.5% of our total assets at September 30, 2017 compared to 17.0% of our total equity and 1.8% of our total assets at December 31, 2016. The aggregate amount of classified assets at the dates indicated was as follows:

	September 30, 2017		December 31, 2016
	(Dollars in thousands)
Doubtful	$	3,330	$	2,880
Substandard	123,175		136,815
Total classified loans	126,505		139,695
Foreclosed assets	13,585		10,838
Total classified assets	$	140,090	$	150,533

Substandard loans at September 30, 2017decreased by $13.6 million from December 31, 2016, which was primarily due to the resolution of the two energy relationships, as well as the resolution of the construction and land relationship with a residential home builder, discussed above in "Allowance for Loan Losses."Substandard non-performing energy loans totaled $51.0 million at September 30, 2017, down $16.6 million from December 31, 2016. The Company continues to take action to improve the risk profile of the criticized energy loans by instituting monthly commitment reductions, obtaining additional collateral, obtaining additional guarantor support and/or requiring additional equity injections or asset sales. 

The Company also has potential problem loans, considered "other loans of concern," that are currently performing and do not meet the criteria for impairment, but where there is the distinct possibility that we might sustain some loss if credit deficiencies are not corrected. These possible credit problems may result in the future inclusion of these loans in the non-performing asset categories and consisted of $47.3 million in loans that were classified as "substandard," but were still accruing interest and were not considered impaired at September 30, 2017 (excluding PCI loans), compared to $21.3 million at December 31, 2016. The $26.0 million increase in other loans of concern from December 31, 2016 was primarily due to two energy relationships totaling $25.6 million and one corporate healthcare finance relationship totaling $13.2 million that were graded substandard accruing in the third quarter of 2017 following a review as part of the Shared National Credit ("SNC") program, which is a regulatory review conducted by the FRB, FDIC and Office of the Comptroller of the Currency ("OCC") of large syndicated loans of at least $20 million that are shared by three or more supervised institutions. Other loans of concern have been considered in management's analysis of potential loan losses.

Securities. Our securities portfolio increased $26.5 million, or 4.7%, to $591.4 million at September 30, 2017 from $564.9 million at December 31, 2016. During the nine months ended September 30, 2017, purchases totaling $2.07 billion offset paydowns and maturities of securities totaling $2.04 billion.

41

Deposits. Total deposits increased $394.9 million, or 6.2%, to $6.76 billion at September 30, 2017 from $6.37 billion at December 31, 2016, primarily due to growth in non-interest-bearing demand and savings and money market deposits.

	September 30, 2017		December 31, 2016		Dollar Change			Percent Change
	(Dollars in thousands)
Non-interest-bearing demand	$	1,529,052	$	1,383,951	$	145,101		10.5	%

Total deposits	$	6,760,368	$	6,365,476	$	394,892		6.2	%

Savings and money market deposits increased by $257.4 million compared to December 31, 2016, while non-interest-bearing demand and time deposits increased by $145.1 million and $6.1 million, respectively, for the same period. These increases were partially offset by a $13.7 million reduction in interest-bearing demand deposits compared to December 31, 2016.

Borrowings. FHLB advances increased $164.5 million, or 19.7%, to $998.1 million at September 30, 2017 from $833.7 million at December 31, 2016. At September 30, 2017, the Company was eligible to borrow an additional $1.83 billion from the FHLB.

The table below shows FHLB advances by maturity and weighted average rate at September 30, 2017:

	Balance		Weighted Average Rate
	(Dollars in thousands)
Less than 90 days	$	779,983	1.09	%

Total	$	998,146	1.16	%

Additionally, we have seven available federal funds lines of credit with other financial institutions totaling $250.0 million and were eligible to borrow $84.9 million from the Federal Reserve Bank discount window. At September 30, 2017, we also had a $25.0 million outstanding structured repurchase agreement with Credit Suisse, as well as $56.1 million in overnight repurchase agreements with depositors. Also, at September 30, 2017, subordinated debt totaled $134.4 million, which included $122.5 million of fixed-to-floating rate subordinated notes (reported net of $2.5 million in debt issuance costs.) $75.0 million of these notes were issued by the Company in November 2015, and $50.0 million additional notes were issued in September 2016 when the Company reopened the offering. The $134.4 million of subordinated debt also included $11.9 million of trust preferred securities that were acquired through the merger with LegacyTexas Group, Inc. All subordinated debt is reported net of purchase accounting fair value adjustments and debt issuance costs.

Accrued Expenses and Other Liabilities. Accrued expenses and other liabilities increased $87.5 million, or 153.5%, to $144.5 million at September 30, 2017 from $57.0 million at December 31, 2016. This increase was primarily due to timing of escrow payments.

Shareholders’ Equity. Total shareholders' equity increased by $64.7 million, or 7.3%, to $950.1 million at September 30, 2017 from $885.4 million at December 31, 2016.

The increase in shareholders' equity at September 30, 2017, compared to December 31, 2016, was primarily due to net income of $74.8 million recognized during the nine months ended September 30, 2017, which was partially offset by the payment of quarterly dividends totaling $0.45 per common share, or $21.6 million, during the nine months ended September 30, 2017.

Comparison of Results of Operations for the Three Months Ended September 30, 2017 and 2016

General. Net income for the three months ended September 30, 2017 was $28.7 million, an increase of $1.5 million, or 5.5%, from net income of $27.2 million for the three months ended September 30, 2016. The increase in net income was driven by a $10.1 million increase in interest income on loans and a $949,000 increase in non-interest income, which was partially offset by a $6.1 million increase in interest expense, a $3.7 million increase in the provision for credit losses, and a $621,000 increase in non-interest expense. Basic earnings per share for the three months ended September 30, 2017 was $0.61, a $0.02 increase from $0.59 for the three months ended September 30, 2016. Diluted earnings per share for the three months ended September 30, 2017 was $0.61, a $0.03 increase from $0.58 for the three months ended September 30, 2016.

Interest Income. Interest income increased by $11.6 million, or 13.9%, to $94.5 million for the three months ended September 30, 2017 from $82.9 million for the three months ended September 30, 2016.

	$	94,463	$	82,911	$	11,552	13.9	%

The $11.6 million increase in interest income for the three months ended September 30, 2017 compared to the three months ended September 30, 2016 was primarily due to a $10.1 million increase in interest income on loans, which was driven by increased volume in the commercial real estate, commercial and industrial and consumer real estate loan portfolios, as well as higher yields earned on commercial and industrial and Warehouse Purchase Program loans. The average balance of commercial real estate loans increased by $306.1 million from the third quarter of 2016, while the average yield earned on this portfolio declined by 13 basis points for the same period, resulting in a $3.1 million increase in interest income. The average balance of commercial and industrial loans increased by $312.5 million from the third quarter of 2016, while the average yield earned on this portfolio increased by 42 basis points for the same period, resulting in a $5.7 million increase in interest income. The average balance of consumer real estate loans increased by $121.2 million compared to the third quarter of 2016, while the average yield earned on this portfolio declined by 17 basis points for the same period, leading to a $908,000 increase in interest income. Despite a $111.3 million decline in the average balance compared to the prior year period, interest income on Warehouse Purchase Program loans increased by $607,000 due to a 58 basis point increase in the average yield earned for the third quarter of 2017, compared to the same quarter last year.

Interest income on loans for the third quarter of 2017 included $750,000 in accretion of purchase accounting fair value adjustments on acquired loans, which includes $281,000 on acquired commercial real estate loans, $88,000 on acquired commercial and industrial loans, $53,000 on acquired construction and land loans and $328,000 on acquired consumer loans.

Interest Expense. Interest expense increased by $6.1 million, or 64.3%, to $15.5 million for the three months ended September 30, 2017 from $9.4 million for the three months ended September 30, 2016.

	Three Months Ended September 30,				Dollar Change		Percent Change

	(Dollars in thousands)

	$	15,499	$	9,431	$	6,068	64.3	%

The increase in interest expense for the three months ended September 30, 2017 compared to the same period in 2016 was primarily due to higher average deposit and borrowing rates and increased volume in all deposit products. The average balance of savings and money market and time deposits increased by $442.8 million and $45.7 million, respectively, compared

44

to the third quarter of 2016, while the average rates paid on these deposits increased by 35 basis points and 30 basis points, respectively, compared to the prior year period. These increases in volume and rate on savings and money market and time deposits increased interest expense compared to the third quarter of 2016 by $2.9 million and $1.2 million, respectively. The average rate paid on interest-bearing demand deposits increased by 18 basis points compared to the third quarter of 2016, while the average balance of interest-bearing demand deposits increased by $53.6 million for the same period. A $155.4 million decrease in the average balance of borrowings from the third quarter of 2016 was more than offset by a 66 basis point increase in the average rate, resulting in a $1.6 million increase in interest expense on borrowed funds.

Net Interest Income. Net interest income increased by $5.5 million, or 7.5%, to $79.0 million for the three months ended September 30, 2017 from $73.5 million for the three months ended September 30, 2016. The net interest margin for the third quarter of 2017 was 3.71%, a seven basis point decrease from the third quarter of 2016. The average yield on earning assets for the third quarter of 2017 was 4.44%, a 17 basis point increase from the third quarter of 2016. The average cost of interest-bearing liabilities for the third quarter of 2017 was 0.97%, up 34 basis points from the third quarter of 2016.

Provision for Credit Losses. The Company recorded a provision for credit losses of $7.2 million for the quarter ended September 30, 2017, up $3.7 million from $3.5 million for the quarter ended September 30, 2016. For more information about the Company's allowance for loan losses, please see "Management's Discussion and Analysis - Comparison of Financial Condition at September 30, 2017 and December 31, 2016 - Allowance for Loan Losses" contained in Item 2 of this report.

Non-interest Income. Non-interest income increased by $949,000, or 8.4%, to $12.2 million for the three months ended September 30, 2017 from $11.3 million for the three months ended September 30, 2016.

¹N/M - not meaningful

The $949,000 increase in non-interest income from the third quarter of 2016 was primarily due to a $1.8 million increase in gain (loss) on sale and disposition of assets, due to a loss of $1.5 million recorded in the third quarter of 2016 on the sale of the Company's Federal Housing Administration (“FHA”) loan portfolio, compared to a $365,000 gain on the sale of a branch location recorded in the third quarter of 2017. Service charges and other fees decreased by $379,000, which was driven by a $355,000 decrease in commercial loan fee income (consisting of syndication, arrangement, non-usage and pre-payment fees). Net gains on the sale of mortgage loans held for sale during the third quarter of 2017 decreased by $401,000 compared to the third quarter of 2016, which included gains recognized on $60.2 million of one-to four-family mortgage loans that were sold or committed for sale and fair value changes on mortgage derivatives and mortgage fees collected during the 2016 period, compared to $52.4 million for the third quarter of 2017.

45

Non-interest Expense. Non-interest expense increased by $621,000, or 1.6%, to $40.3 million for the three months ended September 30, 2017, from $39.7 million for the three months ended September 30, 2016.

	$	40,295	$	39,674	$	621		1.6	%

The $621,000 increase in non-interest expense from the third quarter of 2016 was primarily related to a $298,000 increase in data processing expense due to increased costs for system upgrades to enhance customer service and increase operating efficiency, and a $290,000 increase in outside professional services expense related to higher consulting, legal and compliance costs. Salaries and employee benefits expense also increased by $257,000 compared to the 2016 period, which was driven by merit increases, as well as increased health care costs and higher share-based compensation expense related to new stock awards granted in the 2017 period. These increases were partially offset by a $523,000 decline in occupancy and equipment expense, primarily related to an early termination fee collected from a tenant in the 2017 period, as well as closed locations.

Income Tax Expense. For the three months ended September 30, 2017, we recognized income tax expense of $15.0 million on our pre-tax income, which was an effective tax rate of 34.4%, compared to income tax expense of $14.4 million for the three months ended September 30, 2016, which was an effective tax rate of 34.6%.

Comparison of Results of Operations for the Nine Months Ended September 30, 2017 and 2016

General. Net income for the nine months ended September 30, 2017 was $74.8 million, an increase of $2.3 million, or 3.2%, from net income of $72.5 million for the nine months ended September 30, 2016. The increase in net income was driven by increased net interest income, partially offset by increased provision for credit losses and non-interest expense and lower non-interest income. Basic earnings per share for the nine months ended September 30, 2017 was $1.60, an increase of $0.04 from $1.56 for the nine months ended September 30, 2016. Diluted earnings per share for the nine months ended September 30, 2017 was $1.58, an increase of $0.02 from $1.56 for the nine months ended September 30, 2016.

Interest Income. Interest income increased by $37.9 million, or 16.3%, to $270.7 million for the nine months ended September 30, 2017 from $232.9 million for the nine months ended September 30, 2016.

The $37.9 million increase in interest income for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016 was primarily due to a $35.0 million, or 15.8%, increase in interest income on loans, which was driven by increased volume in commercial real estate, commercial and industrial, construction and land and consumer real estate loans. The average balance of commercial real estate loans increased by $388.9 million, resulting in a $13.7 million increase in interest income. The average balance of commercial and industrial loans increased by $323.7 million, and when combined with the impact of the complete amortization of a $4.7 million discount on a purchased energy loan that occurred during the nine months ended September 30, 2017, resulted in an $18.6 million increase in interest income. The average balance of consumer real estate loans increased by $128.8 million, increasing interest income by $3.1 million. The increases in interest income were partially offset by a $605,000 decline in interest income recorded on other consumer loans, the average balance of which declined by $13.4 million. Despite a $100.1 million decline in the average balance of Warehouse Purchase Program loans compared to the prior year period, interest income on Warehouse Purchase Program loans increased by $176,000 due to a 41 basis point increase in the average yield earned for the nine months ended September 30, 2017, compared to the same period last year.

Interest Expense. Interest expense increased by $14.8 million, or 60.2%, to $39.5 million for the nine months ended September 30, 2017 from $24.7 million for the nine months ended September 30, 2016.

The increase in interest expense for the nine months ended September 30, 2017 compared to the same period in 2016, was primarily due to an increase in interest expense on deposits, which was driven by increased rates paid on all deposit categories during the nine months ended September 30, 2017 compared to the same period in 2016, which included a 30 basis point increase in the average rate paid on savings and money market deposits and a 26 basis point increase in the average rate paid on time deposits. Additionally, volume in all deposit categories increased during the nine months ended September 30, 2017 compared to the same period in 2016, which included a $474.6 million increase in the average balance of savings and

money market deposits and a $165.1 million increase in the average balance of time deposits. Interest expense on borrowings for the nine months ended September 30, 2017 increased by $3.4 million compared to the nine months ended September 30, 2016, due to a 59 basis point increase in the average rate paid on borrowings.

Net Interest Income. Net interest income increased by $23.0 million, or 11.1%, to $231.2 million for the nine months ended September 30, 2017 from $208.2 million for the nine months ended September 30, 2016. The net interest margin decreased by one basis point to 3.82% for the nine months ended September 30, 2017 from 3.83% for the same period last year. The net interest rate spread decreased by eight basis points to 3.61% for the nine months ended September 30, 2017 from 3.69% for the same period last year. The average yield on earning assets for the nine months ended September 30, 2017 was 4.48%, a 20 basis point increase from the nine months ended September 30, 2016, while the average cost of interest-bearing liabilities increased 28 basis points.

Provision for Credit Losses. The provision for credit losses was $35.7 million for the nine months ended September 30, 2017, an increase of $16.6 million from $19.1 million for the nine months ended September 30, 2016. The increase in the provision for credit losses was primarily related to increased loan loss reserves allocated to the corporate healthcare finance portfolio, which is reported on the balance sheet as commercial and industrial loans and totaled $46.0 million at September 30, 2017. During the first quarter of 2017, the Company charged-off its $16.4 million interest in a large syndicated credit within the corporate healthcare finance portfolio. Also, during the third quarter of 2017, the Company charged-off $11.9 million on the resolution of two reserve-based energy relationships, which also contributed to the higher provision expense. For more information about the Company's allowance for loan losses, please see "Management's Discussion and Analysis - Comparison of Financial Condition at September 30, 2017 and December 31, 2016 - Allowance for Loan Losses" contained in Item 2 of this report.

Non-interest Income. Non-interest income decreased by $3.0 million, or 7.5%, to $36.7 million for the nine months ended September 30, 2017 from $39.7 million for the nine months ended September 30, 2016.

¹N/M - not meaningful

The decrease in non-interest income for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016 was primarily due to decreases in gain on sale and disposition of assets and other non-interest income. Gain on sale and disposition of assets for the nine months ended September 30, 2016 included gains totaling $5.1 million recorded in the 2016 period on the sale of two buildings and the Company's insurance subsidiary operations; this $5.1 million in gains was partially offset by a $1.5 million loss recorded in 2016 on the sale of the Company's FHA loan portfolio. Comparatively, gain on sale and disposition of assets for the nine months ended September 30, 2017 included $1.7 million in gains recorded on the sale of one branch location and one parcel of land. Other non-interest income declined by $1.4 million for the nine months ended September 30, 2016 due to $1.3 million in income recorded from insurance activities, which was not repeated in the 2017 period due to the above-mentioned sale of the Company’s insurance subsidiary operations. The $840,000 increase in service charges and other fees compared to the nine months ended September 30, 2016 included a $510,000 increase in Warehouse Purchase Program fee income and a $535,000 increase in debit card interchange income and Mastercard incentive accruals, partially offset by a $379,000 decrease in insufficient funds fees. Net gains on the sale of mortgage loans held for sale during the nine months ended September 30, 2017 decreased by $447,000 compared to the nine months ended September 30, 2016, which included gains recognized on $160.8 million of one-to four-family mortgage loans that were sold or committed for sale and fair value changes on mortgage derivatives and mortgage fees collected during the 2016 period, compared to $148.4 million for the nine months ended September 30, 2017.

Non-interest Expense. Non-interest expense increased by $2.8 million, or 2.4%, to $119.6 million for the nine months ended September 30, 2017 from $116.8 million for the nine months ended September 30, 2016.

	$	119,636	$	116,829	$	2,807		2.4	%

The increase in non-interest expense included a $2.9 million increase in salaries and employee benefits expense for the nine months ended September 30, 2017, which was driven by merit increases and an increase in the average number of employees in the 2017 period, as well as increases in share-based compensation, performance incentive accruals, health care expenses, and payroll taxes. The increase in salaries and employee benefits expense was partially offset by a reduction in expense related to the third quarter 2016 pay-off of one of the Company's ESOP loans and additional deferred salary costs related to loan originations that will be accounted for over the lives of the related loans. Data processing expense increased by $1.1 million, primarily due to increased costs compared to the prior year for system upgrades to enhance customer service and increase operating efficiency, while outside professional services expense increased by $606,000 due to higher legal and compliance costs in the 2017 period. These increases were partially offset by declines of $683,000 in occupancy and equipment expense and $319,000 in office operations expense, primarily resulting from an early termination fee collected from a tenant in the 2017 period, as well as renegotiated contracts and closed locations. Other non-interest expense declined by $550,000 due to lower debit card fraud losses in the 2017 period, which was partially offset by increased lending-related expenses.

Income Tax Expense. For the nine months ended September 30, 2017, we recognized income tax expense of $37.7 million on our pre-tax income, which was an effective tax rate of 33.5%, compared to income tax expense of $39.4 million for the nine months ended September 30, 2016, which was an effective tax rate of 35.2%. The decrease in the effective tax rate in the 2017 period primarily resulted from the adoption of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, in the 2017 period, which changed the tax effect of the difference between the amount of share-based compensation cost recognized for financial reporting purposes and the amount deducted on the Company's tax return for share-based payment awards. Previously, the tax effects of income tax deductions in excess of compensation cost (windfalls) and the tax effects of compensation cost in excess of income tax deductions (shortfalls) were recorded in equity to the extent of previously recognized windfalls, with the remainder recorded in income tax expense.  Under ASU 2016-09, all tax effects of windfalls and shortfalls related to share-based payments are recorded through the income statement.  The 2016 period also included a significant difference between the book basis and tax basis of the LegacyTexas Insurance Services assets sold during that period.

Average Balances, Net Interest Income, Yields Earned and Rates Paid

The following table presents, for the periods indicated, the total dollar amount of interest income from average interest-earning assets and the resultant yields, as well as the interest expense on average interest-bearing liabilities, expressed both in dollars and rates. Also presented are the weighted average yields on interest-earning assets, rates paid on interest-bearing liabilities and the resultant spread. All average balances are daily average balances. Non-accruing loans have been included in the table as loans carrying a zero yield. Yields earned and rates paid are calculated at the portfolio level using the actual number of days in each month over the actual number of days in the year, with the exception of the securities portfolios and the consumer real estate and loans held for sale loan portfolios, which are calculated using 30 days in a month over 360 days in a year.

Rate/Volume Analysis

The following table presents the dollar amount of changes in interest income and interest expense for major components of interest-earning assets and interest-bearing liabilities. It distinguishes between the changes related to outstanding balances and those due to changes in interest rates. The change in interest attributable to rate has been determined by applying the change in rate between periods to average balances outstanding in the earlier period. The change in interest due to volume has been determined by applying the rate from the earlier period to the change in average balances outstanding between periods. Changes attributable to both rate and volume which cannot be segregated have been allocated proportionately based on the changes due to rate and the changes due to volume.

Liquidity

Management maintains a liquidity position that it believes will adequately provide funding for loan demand and deposit run-off that may occur in the normal course of business. The Company relies on a number of different funding sources in order to meet its potential liquidity demands. The primary funding sources are increases in deposit accounts and cash flows from loan payments and the securities portfolio.

Management also has several secondary sources of funds available to meet potential liquidity demands. At September 30, 2017, the Company had additional borrowing capacity of $1.83 billion with the FHLB and $250.0 million in federal funds lines of credit available with other financial institutions. The Company may also use the discount window at the Federal Reserve Bank as a source of short-term funding. Federal Reserve Bank borrowing capacity varies based upon securities pledged to the discount window line. At September 30, 2017, securities pledged had a collateral value of $84.9 million.

At September 30, 2017, the Company had classified 69.4% of its securities portfolio as available for sale (including pledged securities), providing an additional source of liquidity. Management believes that because active markets exist and our securities portfolio is of high quality, our available for sale securities are marketable. Selling participations in loans we originate, including portions of commercial real estate loans, creates another source of liquidity and allows us to manage borrower concentration risk as well as interest rate risk.

Liquidity management is both a daily and long-term function of business management. Short-term excess liquidity is generally placed in short-term investments, such as overnight deposits at the Federal Reserve Bank and correspondent banks. On a longer term basis, we maintain a strategy of investing in various lending products and investment securities, including mortgage-backed securities.

Planning for the Company's normal business liquidity needs, both expected and unexpected, is done on a daily and short-term basis through the cash management function. On a longer-term basis it is accomplished through the budget and strategic planning functions, with support from internal asset/liability management software model projections.

The Liquidity Committee monitors liquidity positions and projections. Liquidity contingency planning is added to the Committee's process by focusing on possible scenarios that would stress liquidity beyond the Bank's normal business liquidity needs. These scenarios may include macro-economic and bank specific situations focusing on high probability-high impact, high probability-low impact, low probability-high impact, and low probability-low impact stressors.

Management recognizes that the factors and conditions leading up to and occurring during a liquidity stress event cannot be precisely defined or listed. Nevertheless, management believes that liquidity stress events can be categorized into sources and uses of liquidity, and levels of severity, with responses that apply to various situations.

The Company, which is a separate legal entity from the Bank and must provide for its own liquidity, had liquid assets of $24.0 million on an unconsolidated basis at September 30, 2017. In addition to its operating expenses, the Company is responsible for paying any dividends declared to its shareholders, funds paid out for Company stock repurchases, and payments on trust-preferred securities and subordinated debt held at the Company level. The Company has the ability to receive dividends or capital distributions from the Bank, although there are regulatory restrictions on the ability of the Bank to pay dividends. See “How We Are Regulated - Limitations on Dividends and Other Capital Distributions” under Item 1 and Note 16 of the Notes to Consolidated Financial Statements contained in Item 8 of the Company's 2016 Form 10-K.

The Company uses its sources of funds primarily to meet its expenses, pay maturing deposits and fund withdrawals, and to fund loan commitments. Total approved loan commitments (including Warehouse Purchase Program commitments, unused lines of credit and letters of credit) amounted to $2.59 billion and $2.56 billion at September 30, 2017, and December 31, 2016, respectively. It is management's policy to offer deposit rates that are competitive with other local financial institutions. Based on this management strategy, we believe that a majority of maturing deposits will remain with the Company. Certificates of deposit scheduled to mature in one year or less at September 30, 2017 totaled $1.00 billion with a weighted average rate of 1.04%.

During the nine months ended September 30, 2017, cash and cash equivalents increased by $38.1 million, or 13.2%, to $327.3 million at September 30, 2017 from $289.2 million at December 31, 2016. Operating activities provided cash of $192.0 million and financing activities provided cash of $535.0 million, which was partially offset by cash used in investing activities of $688.8 million. Primary sources of cash for the nine months ended September 30, 2017 included proceeds from pay-offs of Warehouse Purchase Program loans totaling $16.04 billion, proceeds from FHLB advances totaling $175.0 million, proceeds

from the sale of loans held for sale totaling $149.9 million, and a $394.9 million increase in deposits. Primary uses of cash for the nine months ended September 30, 2017 included originations of Warehouse Purchase Program loans totaling $16.11 billion and net fundings of loans held for investment totaling $586.2 million.

Capital Resources

Consistent with our goal to operate a sound and profitable organization, our policy is for the Company and its subsidiary bank to maintain “well-capitalized” status under the FRB regulations. Based on capital levels at September 30, 2017 and December 31, 2016, the Bank and the Company were considered to be well-capitalized. At September 30, 2017, the Bank's equity totaled $1.04 billion. The Company's consolidated equity totaled $950.1 million, or 10.5% of total assets, at September 30, 2017. Warehouse Purchase Program loan volumes can increase significantly on the last day of the month, potentially leading to a significant difference between the ending and average balance of Warehouse Purchase Program loans. At September 30, 2017, Warehouse Purchase Program loans totaled $1.13 billion, compared to an average balance of $1.02 billion for the three months ended September 30, 2017. Because the capital ratios below are calculated using ending risk-weighted assets and Warehouse Purchase Program loans are risk-weighted at 100%, an end of period increase in these balances can significantly impact the Company's reported capital ratios.

Pursuant to the capital regulations of the FRB and the other federal banking agencies, the Company and the Bank must maintain a capital conservation buffer consisting of additional common equity tier 1 capital greater than 2.5% of risk-weighted assets above the required minimum levels of risk-based common equity tier 1 capital, tier 1 capital and total capital in order to avoid limitations on paying dividends, repurchasing shares, and paying discretionary bonuses. For our fiscal year ending December 31, 2017, the capital conservation buffer rule requires a buffer of greater than 1.25% of risk-weighted assets, which amount will increase by 0.625% yearly until the requirement is fully phased-in on January 1, 2019, when the buffer must exceed 2.5% of risk-weighted assets. At September 30, 2017, the Company's and the Bank's common equity tier 1 capital exceeded the required capital conservation buffer.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Asset/Liability Management

Our Risk When Interest Rates Change. The rates of interest we earn on assets and pay on liabilities generally are established contractually for a period of time. However, market rates change over time. Like other financial institutions, our results of operations are impacted by changes in market interest rates and the interest rate sensitivity of our assets and liabilities. The risk associated with changes in market interest rates and our ability to adapt to these changes is known as interest rate risk and is our most significant market risk.

How We Measure Our Risk of Interest Rate Changes. As part of our attempt to manage our exposure to changes in market interest rates and comply with applicable regulations, we calculate and monitor our interest rate risk. In doing so, we analyze and manage assets and liabilities based on their interest rates and contractual cash flows, timing of maturities, prepayment potential, repricing opportunities, and sensitivity to actual or potential changes in market interest rates.

The Company is subject to interest rate risk to the extent that its interest-bearing liabilities, primarily deposits, FHLB advances and other borrowings, reprice more rapidly or slowly, or at different rates (basis risk) than its interest-earning assets, primarily loans and investment securities.

The Bank calculates interest rate risk by entering relevant contractual and projected information into its asset/liability management software simulation model. Data required by the model includes balance, rate, pay down schedule, and maturity. For items that contractually reprice, the repricing index, spread, and frequency are entered, including any initial, periodic, and lifetime interest rate caps and floors.

The Bank has adopted an asset and liability management policy. This policy sets the foundation for monitoring and managing the potential for adverse effects of material prolonged increases or decreases in interest rates on our results of operations. The Board of Directors sets the asset and liability policy for the Bank, which is implemented by the Asset/Liability Management Committee.

The purpose of the Asset/Liability Management Committee is to monitor, communicate, coordinate, and direct asset/liability management consistent with our business plan and board-approved policies. The Committee directs and monitors the volume and mix of assets and funding sources, taking into account relative costs and spreads, interest rate sensitivity and liquidity needs. The objectives are to manage assets and funding sources to produce results that are consistent with liquidity, capital adequacy, interest rate risk, growth, and profitability goals.

The Committee meets on a quarterly basis to, among other things, protect capital through earnings stability over the interest rate cycle, maintain our well-capitalized status, and provide a reasonable return on investment. The Committee recommends appropriate strategy changes based on this review. The Committee is responsible for reviewing and reporting the effects of policy implementation and strategies to the Board of Directors at least quarterly. Senior managers oversee the process on a daily basis.

A key element of the Bank’s asset/liability management strategy is to protect earnings by managing the inherent maturity and repricing mismatches between its interest-earning assets and interest-bearing liabilities. The Bank generally manages such earnings exposure through the addition of loans, investment securities and deposits with risk mitigating characteristics and by entering into appropriate term FHLB advance agreements.

As part of its efforts to monitor and manage interest rate risk, the Bank uses the economic value of equity (“EVE”) methodology adopted by the Federal Financial Institutions Examination Council ("FFIEC") as part of its capital regulations. In essence, the EVE approach calculates the difference between the present value of expected cash flows from assets and liabilities. In addition to monitoring selected measures of EVE, management also calculates and monitors potential effects on net interest income resulting from increases or decreases in market interest rates. This approach uses the earnings at risk (“EAR”) methodology adopted by the Joint Agency Policy Statement on Interest Rate Risk as part of its capital regulations. EAR calculates estimated net interest income using a flat balance sheet approach over a twelve month time horizon. The EAR process is used in conjunction with EVE measures to identify interest rate risk on both a global and account level basis. Management and the Board of Directors review EVE and EAR measurements at least quarterly to review historical trends, projected measurements, and to determine whether the Bank's interest rate exposure is within the limits established by the Board of Directors.

57

The Bank's asset/liability management strategy sets acceptable limits for the percentage change in EVE and EAR given changes in interest rates. For instantaneous, parallel, and sustained interest rate increases or decreases of 100 basis points, the Bank's policy indicates that change in EVE should not decrease by more than 5%, and for increases of 200, 300, and 400 basis points, the change in EVE should not exceed a 10%, 12.5% and 15% decrease, respectively. For an instantaneous, parallel, and sustained interest rate increase or decrease of 100 basis points, the Bank's policy indicates that the change in EAR should not exceed a 7% decrease, and for increases of 200, 300, and 400 basis points, the change in EAR should not exceed decreases of 10%, 13%, and 15%, respectively.

As illustrated in the tables below, the Bank was within policy limits for all scenarios tested. The tables presented below, as of September 30, 2017, and December 31, 2016, are internal analyses of our interest rate risk as measured by changes in EVE and EAR for instantaneous, parallel, and sustained shifts for all market rates and yield curves, in 100 basis point increments, up 400 basis points and down 100 basis points.

As illustrated in the tables below, our EVE would be negatively impacted by a parallel, instantaneous, and sustained increase in market rates. Such an increase in rates would negatively impact EVE as a result of the duration of assets, including loans and investments, being longer than the duration of liabilities, primarily deposit accounts and FHLB borrowings. In rising rate environments, deposits are more beneficial to the Bank’s EVE than comparable wholesale funding. As illustrated in the table below, at September 30, 2017, our EAR would be positively impacted by a parallel, instantaneous, and sustained increase in market rates. Our EVE and EAR would also be negatively impacted by a 100 basis point decline in market rates.

The Bank's EVE was $1.30 billion, or 14.49%, of the market value of portfolio assets as of September 30, 2017, a $34.3 millionincrease from $1.27 billion, or 15.30%, of the market value of portfolio assets as of December 31, 2016. Based upon the assumptions utilized, an immediate 200 basis point increase in market interest rates would result in a $49.2 million decrease in our EVE at September 30, 2017 compared to a $48.9 million decrease at December 31, 2016, and would result in an eight basis point decrease in our EVE ratio to 14.41% at September 30, 2017 compared to a nine basis point decrease to 15.21% at December 31, 2016. An immediate 100 basis point decrease in market interest rates would result in a $50.8 million decrease in our EVE at September 30, 2017 compared to a $34.5 million decrease at December 31, 2016, and would result in a 77 basis point decrease in our EVE ratio to 13.72% at September 30, 2017, as compared to a 66 basis point decrease in our EVE ratio to 14.64% at December 31, 2016.

The Bank's projected EAR for the twelve months ending September 30,2018 is $333.3 million, compared to $310.7 million for the twelve months ending December 31, 2017. Based on the assumptions utilized, an immediate 200 basis point increase in market rates would result in a $3.2 million, or 0.97%, increase in net interest income for the twelve months ending September 30,2018 compared to an $899,000, or 0.29%, increase for the twelve months ending December 31, 2017. An immediate 100 basis point decrease in market rates would result in a $6.6 million decrease in net interest income for the twelve months ending September 30,2018 compared to a $12.9 million decrease for the twelve months ending December 31, 2017.

We have implemented a strategic plan to mitigate interest rate risk. This plan includes the ongoing review of our current and projected mix of fixed rate versus variable rate loans, investments, deposits, and borrowings. When available and appropriate, high quality adjustable rate assets are purchased or originated. These assets generally may reduce our sensitivity to upward interest rate shocks. On the liability side of the balance sheet, borrowings are added as appropriate. These borrowings will be of a size and term so as to mitigate the impact of duration mismatches, reducing our sensitivity to upward interest rate shocks. These strategies are implemented as needed and as opportunities arise to mitigate interest rate risk without materially sacrificing earnings.

In managing our mix of assets and liabilities, while considering the relationship between long and short term interest rates, market conditions, and consumer preferences, we may place somewhat greater emphasis on maintaining or increasing the Bank’s net interest margin than on strictly matching the interest rate sensitivity of its assets and liabilities.

Management also believes that at times the increased net income which may result from a mismatch in the actual maturity, repricing, or duration of its asset and liability portfolios can provide sufficient returns to justify the increased exposure to sudden and unexpected increases or decreases in interest rates which may result from such a mismatch. Management believes that the Bank’s level of interest rate risk is acceptable under this approach.

In evaluating the Bank’s exposure to market interest rate movements, certain shortcomings inherent in the method of analysis presented in the foregoing table must be considered. For example, although certain assets and liabilities may have similar maturities or repricing characteristics, their interest rate drivers may react in different degrees to changes in market interest rates (basis risk). Also, the interest rates on certain types of assets and liabilities may fluctuate in advance of changes in market interest rates, while interest rates on other types may lag behind changes in market interest rates. Additionally, certain assets, such as adjustable rate mortgages, have features which restrict changes in interest rates over the life of the asset (time to initial interest rate reset; interest rate reset frequency; initial, periodic, and lifetime caps and floors). Further, in the event of a significant change in market interest rates, loan and securities prepayment and time deposit early withdrawal levels may deviate significantly from those assumed in the table above. Assets with prepayment options and liabilities with early withdrawal options are being monitored, with assumptions stress tested on a regular basis. Current market rates and customer behavior are being considered in the management of interest rate risk. Finally, the ability of many borrowers to service their debt may decrease in the event of an interest rate increase. The Bank considers all of these factors in monitoring its exposure to interest rate risk. Of note, the current historically low interest rate environment has resulted in asymmetrical interest rate risk. The interest rates on certain repricing assets and liabilities cannot be fully shocked downward.

The Board of Directors and management believe that the Bank’s ability to successfully manage and mitigate its exposure to interest rate risk is strengthened by several key factors. For example, the Bank manages its balance sheet duration and overall interest rate risk by placing a preference on originating and retaining adjustable rate loans. In addition, the Bank borrows at various maturities from the FHLB to mitigate mismatches between the asset and liability portfolios. Furthermore, the investment securities portfolio is used as a primary interest rate risk management tool through the duration and repricing targeting of purchases and sales.

Item 4. Controls and Procedures

An evaluation was performed under the supervision and with the participation of the Company's management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities and Exchange Act of 1934, as amended) as of September 30, 2017. Based on that evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective as of the end of the period covered by this quarterly report. There has been no change in the Company's internal controls over financial reporting during the quarter that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

While the Company believes the present design of its disclosure controls and procedures is effective to achieve its goals, future events affecting its business may cause the Company to modify its disclosure controls and procedures. The Company does not expect that its disclosure controls and procedures and internal control over financial reporting will prevent all error and fraud. A control procedure, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control procedure are met. Because of the inherent limitations in all control procedures, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns in controls or procedures can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual actions of some persons, by collusion of two or more people, or by management override of the control. The design of any control procedure is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control procedure, misstatements due to error or fraud may occur and not be detected.

Basis of Financial Statement Presentation

Basis of Financial Statement Presentation

The accompanying consolidated interim financial statements of LegacyTexas Financial Group, Inc. (the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles ("US GAAP") and with the rules and regulations of the Securities and Exchange Commission for interim financial reporting. Accordingly, they do not include all of the information and footnotes required for complete financial statements. In the opinion of management, all normal and recurring adjustments which are considered necessary to fairly present the results for the interim periods presented have been included. Certain items in prior periods were reclassified to conform to the current presentation. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 (“2016 Form 10-K”). Interim results are not necessarily indicative of results for a full year.

In preparing the financial statements, management is required to make estimates and assumptions that affect the recorded amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the period. Actual results could differ from those estimates. For further information with respect to significant accounting policies followed by the Company in preparation of its consolidated financial statements, refer to the 2016 Form 10-K.

The accompanying Unaudited Consolidated Interim Financial Statements include the accounts of the Company, whose business primarily consists of the operations of its wholly owned subsidiary, LegacyTexas Bank (the “Bank”).

Earnings Per Common Share

Earnings Per Share [Abstract]

Earnings Per Common Share

Earnings Per Common Share

Basic earnings per common share is computed by dividing net income (which has been adjusted for distributed and undistributed earnings to participating securities) by the weighted-average number of common shares outstanding for the period, reduced for average unallocated ESOP shares and average unvested restricted stock awards. Unvested restricted stock awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method described in Accounting Standards Codification ("ASC") 260-10-45-60B. Diluted earnings per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock (such as stock awards and options) were exercised or converted to common stock, or resulted in the issuance of common stock that then shared in the Company’s earnings. Diluted earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding for the period increased for the dilutive effect of unexercised stock options and unvested restricted stock awards. The dilutive effect of the unexercised stock options and unvested restricted stock awards is calculated under the treasury stock method utilizing the average market value of the Company’s stock for the period. A reconciliation of the numerator and denominator of the basic and diluted earnings per common share computation for the three and nine months endedSeptember 30, 2017 and 2016 is as follows:

Other-than-Temporary Impairment

In determining other-than-temporary impairment for debt securities, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than amortized cost; (2) the financial condition and near-term prospects of the issuer; (3) whether the market decline was affected by macroeconomic conditions; and (4) whether the Company has the intent and ability to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.

As of September 30, 2017, 191 securities had unrealized losses, 63 of which had been in an unrealized loss position for over 12 months at September 30, 2017. The Company does not believe these unrealized losses are other-than-temporary and, at September 30, 2017, believes that full recovery of the amortized cost basis is more likely than not. All principal and interest payments are being received on time and in full.

The allowance for loan losses and related provision expense are susceptible to change if the credit quality of our loan portfolio changes, which is evidenced by many factors, including but not limited to charge-offs and non-performing loan trends. Generally, consumer real estate lending has a lower credit risk profile compared to other consumer lending (such as automobile loans). Commercial real estate and commercial and industrial lending, however, can have higher risk profiles than consumer loans due to these loans being larger in amount and non-homogeneous in structure and term. Changes in economic conditions, the mix and size of the loan portfolio and individual borrower conditions can dramatically impact our level of allowance for loan losses in relatively short periods of time.

The allowance for loan losses is maintained to cover incurred losses that are estimated in accordance with US GAAP. It is our estimate of credit losses inherent in our loan portfolio at each balance sheet date. Our methodology for analyzing the allowance for loan losses consists of general and specific components. For the general component, we stratify the loan portfolio into homogeneous groups of loans that possess similar loss potential characteristics and apply a loss ratio to these groups of loans to estimate the credit losses in the loan portfolio. We use both historical loss ratios and qualitative loss factors assigned to major loan collateral types to establish general component loss allocations, inclusive of estimated loss emergence periods. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data and external economic indicators, which are not yet reflected in the historical loss ratios, and that could impact the Company's specific loan portfolios. The Allowance for Loan Loss Committee sets and adjusts qualitative loss factors by regularly reviewing changes in underlying loan composition and the seasonality of specific portfolios. The Allowance for Loan Loss Committee also considers credit quality and trends relating to delinquency, non-performing and adversely rated loans within the Company's loan portfolio when evaluating qualitative loss factors. Additionally, the Allowance for Loan Loss Committee adjusts qualitative factors to account for the potential impact of external economic factors, including the unemployment rate, vacancy and capitalization rates and other pertinent economic data specific to our primary market area and lending portfolios.

For the specific component, the allowance for loan losses includes loans where management has concerns about the borrower's ability to repay and on individually analyzed loans found to be impaired. Management evaluates current information and events regarding a borrower's ability to repay its obligations and considers a loan to be impaired when the ultimate collectability of amounts due, according to the contractual terms of the loan agreement, is in doubt. If an impaired loan is collateral-dependent, the fair value of the collateral, less the estimated cost to sell, is used to determine the amount of impairment. If an impaired loan is not collateral-dependent, estimated discounted cash flows are used to determine the amount of impairment, if any. For impaired loans, the amount of the impairment can be adjusted, based on current data, until such time as the actual basis is established by acquisition of the collateral or until the basis is collected. Impairment losses are reflected in the allowance for loan losses through a charge to the provision for credit losses. Subsequent recoveries are credited to the allowance for loan losses. Cash receipts for accruing loans are applied to principal and interest under the contractual terms of the loan agreement. Cash receipts on impaired loans for which the accrual of interest has been discontinued are applied first to principal.

Large groups of smaller-balance homogeneous loans are collectively evaluated for impairment. As a result, the Company does not separately identify consumer real estate loans less than $417 or individual consumer non-real estate secured loans for impairment disclosures. The Company considers these loans to be homogeneous in nature due to the smaller dollar amount and the similar underwriting criteria.

Changes in the allowance for off-balance sheet credit losses on lending-related commitments and guarantees on credit card debt, included in "accrued expenses and other liabilities" on the consolidated balance sheets, are summarized in the following table. Please see Note 9 - Commitments and Contingent Liabilities for more information.

¹  Loans reported do not include PCI loans.

Past due status is based on the contractual terms of the loan. Loans that are past due 30 days are considered delinquent. Interest income on loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Non-mortgage consumer loans are typically charged off no later than 120 days past due. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans include both smaller balance homogeneous loans that are collectively evaluated for impairment and larger individually classified impaired loans.

All interest accrued but not received for loans placed on nonaccrual status is reversed against interest income. Subsequent receipts on non-accrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

No loans past due over 90 days were still accruing interest at September 30, 2017. At December 31, 2016, $141 of loans past due over 90 days were still accruing interest, which consisted entirely of PCI loans. At September 30, 2017, no PCI loans were considered non-performing loans. No Warehouse Purchase Program loans were non-performing at September 30, 2017 or December 31, 2016. Non-performing (nonaccrual) loans were as follows:

	September 30, 2017		December 31, 2016
Commercial real estate	$	4,064	$	5,195
Commercial and industrial	65,560		86,664

A loan that has been modified is considered a troubled debt restructuring (“TDR”) when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. Modifications to loan terms may include a modification of the contractual interest rate to a below-market rate (even if the modified rate is higher than the original rate), forgiveness of accrued interest, forgiveness of a portion of principal, an extended repayment period or a deed in lieu of foreclosure or other transfer of assets other than cash to fully or partially satisfy a debt. The Company's policy is to place all TDRs on nonaccrual for a minimum period of six months. Loans qualify for return to accrual status once they have demonstrated performance with the restructured terms of the loan agreement for a minimum of six months and the collection of principal and interest under the revised terms is deemed probable. All TDRs are considered to be impaired loans.

The outstanding balances of TDRs are shown below:

	September 30, 2017		December 31, 2016
Nonaccrual TDRs(1)	$	9,389	$	11,701

For loans collateralized by real property and commercial and industrial loans, credit exposure is monitored by internally assigned grades used for classification of loans. A loan is considered “special mention” when management has determined that there is a potential weakness that deserves management's close attention. Loans rated as "special mention" are not adversely classified according to regulatory classifications and do not expose the Company to sufficient risk to warrant adverse classification. A loan is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or the collateral pledged, if any. “Substandard” loans include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected, and the loan may or may not meet the criteria for impairment. Loans classified as “doubtful” have all of the weaknesses of those classified as “substandard” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions and values, “highly questionable and improbable.” All other loans that do not fall into the above mentioned categories are considered “pass” loans. Updates to internally assigned grades are made monthly and/or upon significant developments.

For other consumer loans (non-real estate), credit exposure is monitored by payment history of the loans. Non-performing other consumer loans are on nonaccrual status and are generally greater than 90 days past due.

The recorded investment in loans by credit quality indicators at September 30, 2017 and December 31, 2016, was as follows.

Fair Value Disclosures [Abstract]

Fair Value

Fair Value

ASC 820, “Fair Value Measurements and Disclosures”, establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3: Prices or valuation techniques that require inputs that are both significant and unobservable in the market. These instruments are valued using the best information available, some of which is internally developed, and reflects a reporting entity’s own assumptions about the risk premiums that market participants would generally require and the assumptions they would use.

Assets and Liabilities Measured on a Recurring Basis

Assets and liabilities measured at fair value on a recurring basis are summarized below.

¹  At September 30, 2017, loans held for sale had an aggregate outstanding principal balance of $25,115. There were no mortgage loans held for sale that were 90 days or greater past due or on non-accrual at September 30, 2017.

The following methodologies were used to measure the fair value of financial assets and liabilities valued on a recurring basis:

Securities available for sale - The fair values of securities available for sale are determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities' relationship to other benchmark quoted securities (Level 2 inputs).

Residential mortgage loans held for sale - Mortgage loans held for sale, 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. Interest income on mortgage loans held for sale is recognized based on the contractual rates and reflected in interest income on loans held for sale in the consolidated income statement. The Company has no continuing involvement in any residential mortgage loans sold.

Derivative instruments:

Interest rate lock commitments ("IRLCs") - The estimated fair values of IRLCs 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 IRLCs 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 - These 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.

Loan customer counterparty and financial institution counterparty - 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). Please see Note 6 — Derivative Financial Instruments for more information.

Assets and Liabilities Measured on a Non-Recurring Basis

Assets measured at fair value on a non-recurring basis are summarized below. There were no liabilities measured at fair value on a non-recurring basis at September 30, 2017 or December 31, 2016.

	Fair Value Measurements Using Level 3
	September 30, 2017		December 31, 2016
Assets:
Impaired loans	$	27,241	$	9,274
Foreclosed assets:
Commercial real estate	10,544		10,638
Construction and land	1,756		194
Residential real estate	91		—
Foreclosed assets- other	1,194		6

Impaired loans that are collateral dependent are measured for impairment using the fair value of the collateral adjusted by additional Level 3 inputs, such as discounts of market value, estimated marketing costs and estimated legal expenses. Impaired loans secured by real estate, receivables or inventory had discounts determined by management on an individual loan basis. Impaired loans that are not collateral dependent are measured for impairment by a discounted cash flow analysis using a net present value calculation that utilizes data from the loan file before and after the modification.

Foreclosed assets are measured at the lower of book or fair value less costs to sell using third party appraisals, listing agreements or sale contracts, which may be adjusted by additional Level 3 inputs, such as discounts of market value, estimated marketing costs and estimated legal expenses. Management may also consider additional adjustments on specific properties due to the age of the appraisal, expected holding period, lack of comparable sales, or if the other real estate owned is a special use property. At September 30, 2017, the Company had $43 in residential mortgage loans in the process of foreclosure.

The Credit Risk Management department evaluates the valuations on impaired loans and foreclosed assets at least quarterly. The valuations on impaired loans are reviewed at least quarterly by the Allowance for Loan Loss Committee and are considered in the calculation of the allowance for loan losses. Unobservable inputs, such as discounts to collateral, are monitored and adjusted if market conditions change.

Fair value of financial instruments not recorded at fair value

The carrying amount and fair value information of financial instruments not recorded at fair value in their entirety on a recurring basis on the Company's consolidated balance sheets at September 30, 2017 and at December 31, 2016, were as follows:

The following methods and assumptions were used to estimate the fair values of each class of financial instrument presented:

Cash and cash equivalents - Due to their short term nature, the carrying amount approximates the estimated fair value.

Securities held to maturity - The fair values of these securities is determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities' relationship to other benchmark quoted securities (Level 2 inputs).

Loans held for investment (including Warehouse Purchase Program loans) - Fair value is based on discounted cash flows using current market offering rates, estimated life, and applicable credit risk.

FHLB stock and other restricted securities - The fair value on these securities is their cost basis due to restrictions on transferability.

Accrued interest receivable - Due to their short term nature, the carrying amount approximates the estimated fair value.

Deposits - Fair value is calculated using the FHLB advance curve to discount cash flows based on the estimated life of the deposits.

FHLB advances - Fair value is calculated using the FHLB advance curve to discount cash flows based on the contractual repayment schedule.

Repurchase agreement - The fair value is based on discounting the estimated cash flows using the current rate at which similar borrowings would be made with similar terms and remaining maturities.

Subordinated debt - The estimated fair value is based on current market rates on similar debt in the market.

Accrued interest payable - Due to their short term nature, the carrying amount approximates the estimated fair value.

The fair value of off-balance sheet items is based on the current fees or costs that would be charged to enter into or terminate such arrangements and are not considered significant to this presentation.

	Outstanding Notional Balance		Asset Derivative Fair Value		Liability Derivative Fair Value		Outstanding Notional Balance		Asset Derivative Fair Value		Liability Derivative Fair Value
IRLCs	$	16,232	$	490	$	—	$	10,952	$	379	$	—
Forward mortgage-backed securities trades	28,844		78		7		18,613		36		80
Commercial loan interest rate swaps and caps:
Loan customer counterparty	$	115,277	$	—	$	1,233	$	112,294	$	—	$	1,369
Financial institution counterparty	115,277		1,233		—		112,294		1,369		—

These financial instruments are not designated as hedging instruments and are used for asset and liability management and commercial customers' financing needs. All derivatives are carried at fair value in either other assets or other liabilities.

IRLCs - In the normal course of business, the Company enters into IRLCs 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.

Forward mortgage-backed securities trades - The Company manages the changes in fair value associated with changes in interest rates related to IRLCs by using forward sold commitments known as forward mortgage-backed securities trades. These instruments are typically entered into at the time the IRLC is made.

Interest rate swaps and caps - These derivative positions relate to transactions in which we enter into an interest rate swap or cap with a customer, while at the same time entering into an offsetting interest rate swap or cap with another financial institution. An interest rate swap transaction allows our customer to effectively convert a variable rate loan to a fixed rate. In connection with each swap, we agree 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, we agree 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. In connection with each interest rate cap, we sell a cap to the customer and agree to pay interest if the underlying index exceeds the strike price defined in the cap agreement.  Simultaneously we purchase a cap with matching terms from another financial institution which agrees to pay us if the underlying index exceeds the strike price.

The commercial loan customer counterparty weighted average received and paid interest rates for interest rate swaps outstanding at September 30, 2017 and December 31, 2016 are presented in the following table.

	Weighted-Average Interest Rate
	September 30, 2017				December 31, 2016
	Received		Paid		Received		Paid
Loan customer counterparty	2.52	%	2.52	%	3.12	%	2.36	%

Our credit exposure on interest rate swaps is limited to the net favorable value of all swaps by each counterparty, which was approximately $151 at September 30, 2017 and $118 at December 31, 2016. This credit exposure is partly mitigated as transactions with customers are generally secured by the collateral, if any, securing the underlying transaction being hedged. Our credit exposure, net of collateral pledged, relating to interest rate swaps with upstream financial institution counter-parties was approximately $1,239 at September 30, 2017.  A credit support annex is in place and allows the bank to call collateral from upstream financial institution counter-parties. Collateral levels are monitored and adjusted on a regular basis for changes in interest rate swap values. Our cash collateral pledged for interest rate swaps and included in our interest-bearing deposits, which totaled $1,950 at September 30, 2017 and $1,950 at December 31, 2016, is in excess of our credit exposure.

The initial and subsequent changes in the fair value of IRLCs and the forward sales of mortgage-back securities are recorded in net gain on sale of mortgage loans. These gains and losses were not attributable to instrument-specific credit risk. For interest rate swaps and caps, because we act 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 our results of operations. Income (loss) for the three and nine months endedSeptember 30, 2017 and 2016 was as follows:

Share-based Compensation

Share-based Compensation

The 2017 Omnibus Incentive Plan (the "2017 Plan") was approved at the Company's 2017 annual meeting of shareholders, held on May 22, 2017. Prior to approval of the 2017 Plan by shareholders, the Company had in effect the 2012 and 2007 Equity Incentive Plans (the “Prior Plans” and together with the 2017 Plan, the “Plans”). No further awards will be made under the Prior Plans and shares reserved to make new awards under the Prior Plans have been released; however, shares reserved to fund issued and outstanding awards under the Prior Plans continue to be reserved to provide for those awards.  All awards outstanding under the Prior Plans remain outstanding in accordance with their terms.  Each outstanding award under the Prior Plans continue to be governed solely by the terms of the documents evidencing such award, and no provision of the 2017 Plan is deemed to affect or otherwise modify the rights or obligations of the holders of such awards with respect to their acquisition of Company shares. The 2017 Plan permits the granting of non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and cash awards to participants. Eligible participants under the 2017 Plan include employees and directors (including advisory and emeritus directors) of the Company and its subsidiaries. As of September 30, 2017, no shares had been issued under the 2017 Plan. There are 3,250,000 total shares authorized under the 2017 Plan, with a fungible share rate of 2.5-for-1 for full-value awards (stock-based awards other than stock options and stock appreciation rights.)

The Plans are accounted for under ASC 718, Compensation - Stock Compensation, which requires companies to record compensation cost for share-based payment transactions with employees in return for employment service. Compensation cost is recognized for stock options and restricted stock awards based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with time-based vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. For awards with performance-based vesting conditions, compensation cost is recognized when the achievement of the performance condition is considered probable of achievement. If a performance condition is subsequently determined to be improbable of achievement, compensation cost is reversed.

Compensation cost charged to income for share-based compensation is presented below:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2017		2016		2017		2016
Restricted stock	$	902	$	909	$	2,627	$	2,090
Stock options	1,112		723		2,792		1,765
Income tax benefit	705		571		1,897		1,349

A summary of non-vested share activity in the restricted stock portion of the Company's Plans is presented below:

	Time-Vested Shares				Performance-Based Shares
Nine Months ended September 30, 2016	Shares		Weighted-Average Grant Date Fair Value per Share 1		Shares		Weighted-Average Grant Date Fair Value per Share 2
Beginning balance	246,461		$	20.98	61,800		$	25.02

Ending balance	128,588		$	27.27	73,008		$	39.92

¹  For restricted stock awards with time-based vesting conditions, the grant date fair value is based upon the closing stock price as quoted on the NASDAQ Stock Market on the grant date.

²  For restricted stock awards with performance-based vesting conditions, the value of the award is based upon the closing stock price as quoted on the NASDAQ Stock Market on the date of vesting. Until the final value is determined on the vesting date, the Company estimates the fair value based upon the closing stock price as quoted on the NASDAQ Stock Market near the last business day of each month.

As of September 30, 2017, there was $3,673 of total unrecognized compensation expense related to non-vested restricted shares awarded under the Company's Plans. That expense is expected to be recognized over a weighted-average period of 1.3 years. The total fair value of shares vested during the nine months endedSeptember 30, 2017 and 2016, was $2,819 and $2,615, respectively.

Under the terms of the 2017 Plan, stock options may not be granted with an exercise price less than the fair market value of the Company’s common stock on the date the option is granted and may not be exercised later than ten years after the grant date. The fair market value is the closing stock price as quoted on the NASDAQ Stock Market on the date of grant.

The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. The risk-free interest rate is the implied yield available on U.S. Treasury zero-coupon issues with a remaining term equal to the expected term of the stock option in effect at the time of the grant. The expected term of stock options is based on employees' actual vesting behavior and expected volatilities are based on historical volatilities of the Company’s common stock. Expected dividends are the estimated dividend rate over the expected term of the stock options.

The weighted average fair value of stock options granted during the nine months ended September 30, 2017 and 2016 was $10.74 and $7.76, respectively. The fair value of options granted was determined using the following weighted-average assumptions as of grant date:

	2017		2016
Expected stock price volatility	31.86	%	32.07	%
Expected dividends	1.61	%	1.93	%
Expected term of stock options (years)	6.2		6.3
Risk-free interest rate	2.18	%	1.37	%

A summary of activity in the stock option portion of the Company's Plans is presented below:

Nine Months ended September 30, 2016	Shares		Weighted- Average Exercise Price per Share		Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value
Beginning Balance	1,865,750		$	22.21	8.8	$	6,401

Exercisable at September 30, 2017	1,041,858		$	22.25	7.7	$	18,407

As of September 30, 2017, there was $9,176 of total unrecognized compensation expense related to non-vested stock options. That expense is expected to be recognized over a weighted-average period of 2.2 years. At September 30, 2017, the Company applied an estimated forfeiture rate of 5% based on historical activity. The intrinsic value for stock options is calculated based on the difference between the exercise price of the underlying awards and the market price of our common stock as of the reporting date. The total intrinsic value of stock options exercised was $2,799 and $656 for the nine months ended September 30, 2017 and 2016, respectively.

Effective January 1, 2017, the Company changed the accounting for income taxes upon the vesting of stock options and restricted stock to be in accordance with ASC 718, as modified by Accounting Standards Update ("ASU") 2016-09, Improvements to Employee Share-Based Payment Accounting. Prior to the implementation of ASU 2016-09, the tax effects of income tax deductions in excess of compensation cost (windfalls) were recorded in additional paid-in capital, and the tax effects of compensation cost in excess of income tax deductions (shortfalls) were recorded in additional paid-in capital to the extent of previously recognized windfalls, with the remainder recorded in income tax expense. Under ASU 2016-09, all tax effects of windfalls and shortfalls related to share-based payments are recorded through the income statement.

For the nine months ended September 30, 2017, we recognized income tax deductions in excess of compensation cost of $3,734 for share-based payment awards, which resulted in a tax benefit of $1,307 recorded as a reduction of income tax expense. The tax effect of this windfall is treated as a discrete item in this interim reporting period and is not considered in determining the annual estimated effective tax rate. The classification of excess tax benefits on the statement of cash flows will be shown as an operating activity.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

Commitments and Contingent Liabilities

In the normal course of business, the Company enters into various transactions which, in accordance with US GAAP, are not included in its consolidated balance sheets. The Company enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and standby letters of credit which involve, to varying degrees, elements of credit and interest rate risk. Credit losses up to the face amount of these instruments could occur, although material losses are not anticipated. The Company's credit policies applied to loan originations are also applied to these commitment requests, including obtaining collateral at the exercise of the commitment.

The contractual amounts of financial instruments with off‑balance sheet risk at September 30, 2017 and December 31, 2016, are summarized below. Please see Part I-Item 2-"Off-Balance Sheet Arrangements, Contractual Obligations and Commitments" of this Form 10-Q for information related to commitment maturities.

	September 30, 2017		December 31, 2016
Unused commitments to extend credit	$	1,853,334	$	1,642,528
Unused capacity on Warehouse Purchase Program loans	709,302		892,659
Standby letters of credit	28,649		29,198
Total unused commitments/capacity	$	2,591,285	$	2,564,385

Unused commitments to extend credit - The Company enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Since many commitments expire without being drawn upon, the total contractual amount of commitments does not necessarily represent future cash requirements of the Company. Substantially all of the Company's commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of future loan funding.

Unused capacity on Warehouse Purchase Program loans - In regard to unused capacity on Warehouse Purchase Program loans, the Company has established maximum purchase facility amounts, but reserves the right, at any time, to refuse to buy any mortgage loans offered for sale by each customer, for any reason in the Company's sole and absolute discretion.

Standby letters of credit - Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

In addition to the commitments above, the Company guarantees the credit card debt of certain customers to the merchant bank that issues the credit cards. These guarantees are in place for as long as the guaranteed credit card is open. At September 30, 2017 and December 31, 2016, these credit card guarantees totaled $5,116 and $3,335, respectively. This amount represents the maximum potential amount of future payments under the guarantee, which the Company is responsible for in the event of customer non-payment.

The Company funds an allowance for credit losses on off-balance sheet lending-related commitments and guarantees on credit card debt through a charge to provision for credit losses on the Company's consolidated statement of income. At September 30, 2017 and December 31, 2016, this allowance for credit losses on off-balance sheet lending-related commitments and guarantees on credit card debt, included in "other liabilities" on the Company's consolidated balance sheets, totaled $1,086 and $1,500, respectively.

In addition to the commitments above, the Company had overdraft protection available in the amounts of $85,004 and $85,709 at September 30, 2017 and December 31, 2016, respectively.

The Company, at September 30, 2017 and December 31, 2016, had FHLB letters of credit of $955,025 and $946,338, respectively, pledged to secure public deposits, repurchase agreements, and for other purposes required or permitted by law.

At September 30, 2017 and December 31, 2016, the Company had $1,680 and $2,080, respectively, of unfunded commitments recorded in other liabilities in its consolidated balance sheet related to investments in community development-oriented private equity funds used for Community Reinvestment Act purposes.

Recent Accounting Developments    

Effect of Newly Issued But Not Yet Effective Accounting Standards

In May 2014, the Financial Accounting Standards Board (the "FASB") issued ASU 2014-09, Revenue from Contracts with Customers. This ASU states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU affects entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which deferred the effective date of ASU 2014-09 for public entities to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Our revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. We have completed our initial evaluation of the impact of ASU 2014-09 on components of our non-interest income and have not found any significant changes to our methodology of recognizing revenue. In the fourth quarter of 2017, we will complete this evaluation and finalize disclosures that will be included in our 2018 financial statements, as required by ASU 2014-09, as we will adopt the standard in the first quarter of 2018 with a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be significant.

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurements of Financial Assets and Financial Liabilities. This ASU requires that all equity investments be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under the equity method of accounting or those that result in consolidation of the investee). This ASU also requires that an entity present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, this ASU eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. For public business entities, this ASU is effective for annual periods beginning after December 15, 2017, and interim periods therein. The adoption of this ASU is not expected to have a significant impact on the Company's financial statements and disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases. This ASU requires lessees to put most leases on their balance sheets but recognize expenses in the income statement in a manner similar to current accounting treatment. This ASU changes the guidance on sale-leaseback transactions, initial direct costs and lease execution costs, and, for lessors, modifies the classification criteria and the accounting for sales-type and direct financing leases. For public business entities, this ASU is effective for annual periods beginning after December 15, 2018, and interim periods therein. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is evaluating the impact of this ASU on its financial statements and disclosures.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. This ASU removes the thresholds that companies apply to measure credit losses on financial instruments measured at amortized cost, such as loans, receivables, and held-to-maturity debt securities. Under current US GAAP, companies generally recognize credit losses when it is probable that the loss has been incurred. This revised guidance will remove all recognition thresholds and will require companies to recognize an allowance for lifetime expected credit losses. Credit losses will be immediately recognized through net income; the amount recognized will be based on the current estimate of contractual cash flows not expected to be collected over the financial asset’s contractual term. ASU 2016-13 also amends the credit loss measurement guidance for available for sale debt securities. For public business entities, this ASU is effective for financial statements issued for fiscal years and for interim periods within those fiscal years beginning after December 15, 2019. The Company is evaluating the impact of this ASU on its financial statements and disclosures.

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. This ASU amends the hedge accounting model to enable entities to better portray their risk management activities in their financial statements, by expanding an entity's ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. This ASU eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Additionally, this ASU also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. For public business entities, this ASU is effective for financial statements issued for fiscal years and for interim periods within those fiscal years beginning after December 15, 2018. The Company is evaluating the impact of this ASU on its financial statements and disclosures.

Basis of Financial Statement Presentation (Policies)

9 Months Ended

Sep. 30, 2017

Accounting Policies [Abstract]

Use of Estimates

In preparing the financial statements, management is required to make estimates and assumptions that affect the recorded amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the period. Actual results could differ from those estimates. For further information with respect to significant accounting policies followed by the Company in preparation of its consolidated financial statements, refer to the 2016 Form 10-K.

Consolidation

The accompanying Unaudited Consolidated Interim Financial Statements include the accounts of the Company, whose business primarily consists of the operations of its wholly owned subsidiary, LegacyTexas Bank (the “Bank”). All significant intercompany transactions and balances are eliminated in consolidation.

Other-than-Temporary Impairment

Other-than-Temporary Impairment

In determining other-than-temporary impairment for debt securities, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than amortized cost; (2) the financial condition and near-term prospects of the issuer; (3) whether the market decline was affected by macroeconomic conditions; and (4) whether the Company has the intent and ability to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.

Allowance for Loan Losses

The allowance for loan losses and related provision expense are susceptible to change if the credit quality of our loan portfolio changes, which is evidenced by many factors, including but not limited to charge-offs and non-performing loan trends. Generally, consumer real estate lending has a lower credit risk profile compared to other consumer lending (such as automobile loans). Commercial real estate and commercial and industrial lending, however, can have higher risk profiles than consumer loans due to these loans being larger in amount and non-homogeneous in structure and term. Changes in economic conditions, the mix and size of the loan portfolio and individual borrower conditions can dramatically impact our level of allowance for loan losses in relatively short periods of time.

The allowance for loan losses is maintained to cover incurred losses that are estimated in accordance with US GAAP. It is our estimate of credit losses inherent in our loan portfolio at each balance sheet date. Our methodology for analyzing the allowance for loan losses consists of general and specific components. For the general component, we stratify the loan portfolio into homogeneous groups of loans that possess similar loss potential characteristics and apply a loss ratio to these groups of loans to estimate the credit losses in the loan portfolio. We use both historical loss ratios and qualitative loss factors assigned to major loan collateral types to establish general component loss allocations, inclusive of estimated loss emergence periods. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data and external economic indicators, which are not yet reflected in the historical loss ratios, and that could impact the Company's specific loan portfolios. The Allowance for Loan Loss Committee sets and adjusts qualitative loss factors by regularly reviewing changes in underlying loan composition and the seasonality of specific portfolios. The Allowance for Loan Loss Committee also considers credit quality and trends relating to delinquency, non-performing and adversely rated loans within the Company's loan portfolio when evaluating qualitative loss factors. Additionally, the Allowance for Loan Loss Committee adjusts qualitative factors to account for the potential impact of external economic factors, including the unemployment rate, vacancy and capitalization rates and other pertinent economic data specific to our primary market area and lending portfolios.

For the specific component, the allowance for loan losses includes loans where management has concerns about the borrower's ability to repay and on individually analyzed loans found to be impaired. Management evaluates current information and events regarding a borrower's ability to repay its obligations and considers a loan to be impaired when the ultimate collectability of amounts due, according to the contractual terms of the loan agreement, is in doubt. If an impaired loan is collateral-dependent, the fair value of the collateral, less the estimated cost to sell, is used to determine the amount of impairment. If an impaired loan is not collateral-dependent, estimated discounted cash flows are used to determine the amount of impairment, if any. For impaired loans, the amount of the impairment can be adjusted, based on current data, until such time as the actual basis is established by acquisition of the collateral or until the basis is collected. Impairment losses are reflected in the allowance for loan losses through a charge to the provision for credit losses. Subsequent recoveries are credited to the allowance for loan losses. Cash receipts for accruing loans are applied to principal and interest under the contractual terms of the loan agreement. Cash receipts on impaired loans for which the accrual of interest has been discontinued are applied first to principal.

Large groups of smaller-balance homogeneous loans are collectively evaluated for impairment. As a result, the Company does not separately identify consumer real estate loans less than $417 or individual consumer non-real estate secured loans for impairment disclosures. The Company considers these loans to be homogeneous in nature due to the smaller dollar amount and the similar underwriting criteria.

A loan that has been modified is considered a troubled debt restructuring (“TDR”) when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. Modifications to loan terms may include a modification of the contractual interest rate to a below-market rate (even if the modified rate is higher than the original rate), forgiveness of accrued interest, forgiveness of a portion of principal, an extended repayment period or a deed in lieu of foreclosure or other transfer of assets other than cash to fully or partially satisfy a debt. The Company's policy is to place all TDRs on nonaccrual for a minimum period of six months. Loans qualify for return to accrual status once they have demonstrated performance with the restructured terms of the loan agreement for a minimum of six months and the collection of principal and interest under the revised terms is deemed probable. All TDRs are considered to be impaired loans.

Loans

For loans collateralized by real property and commercial and industrial loans, credit exposure is monitored by internally assigned grades used for classification of loans. A loan is considered “special mention” when management has determined that there is a potential weakness that deserves management's close attention. Loans rated as "special mention" are not adversely classified according to regulatory classifications and do not expose the Company to sufficient risk to warrant adverse classification. A loan is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or the collateral pledged, if any. “Substandard” loans include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected, and the loan may or may not meet the criteria for impairment. Loans classified as “doubtful” have all of the weaknesses of those classified as “substandard” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions and values, “highly questionable and improbable.” All other loans that do not fall into the above mentioned categories are considered “pass” loans. Updates to internally assigned grades are made monthly and/or upon significant developments.

For other consumer loans (non-real estate), credit exposure is monitored by payment history of the loans. Non-performing other consumer loans are on nonaccrual status and are generally greater than 90 days past due.

Past due status is based on the contractual terms of the loan. Loans that are past due 30 days are considered delinquent. Interest income on loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Non-mortgage consumer loans are typically charged off no later than 120 days past due. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans include both smaller balance homogeneous loans that are collectively evaluated for impairment and larger individually classified impaired loans.

All interest accrued but not received for loans placed on nonaccrual status is reversed against interest income. Subsequent receipts on non-accrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Fair Value

The following methods and assumptions were used to estimate the fair values of each class of financial instrument presented:

Cash and cash equivalents - Due to their short term nature, the carrying amount approximates the estimated fair value.

Securities held to maturity - The fair values of these securities is determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities' relationship to other benchmark quoted securities (Level 2 inputs).

Loans held for investment (including Warehouse Purchase Program loans) - Fair value is based on discounted cash flows using current market offering rates, estimated life, and applicable credit risk.

FHLB stock and other restricted securities - The fair value on these securities is their cost basis due to restrictions on transferability.

Accrued interest receivable - Due to their short term nature, the carrying amount approximates the estimated fair value.

Deposits - Fair value is calculated using the FHLB advance curve to discount cash flows based on the estimated life of the deposits.

FHLB advances - Fair value is calculated using the FHLB advance curve to discount cash flows based on the contractual repayment schedule.

Repurchase agreement - The fair value is based on discounting the estimated cash flows using the current rate at which similar borrowings would be made with similar terms and remaining maturities.

Subordinated debt - The estimated fair value is based on current market rates on similar debt in the market.

Accrued interest payable - Due to their short term nature, the carrying amount approximates the estimated fair value.

The fair value of off-balance sheet items is based on the current fees or costs that would be charged to enter into or terminate such arrangements and are not considered significant to this presentation.

Impaired loans that are collateral dependent are measured for impairment using the fair value of the collateral adjusted by additional Level 3 inputs, such as discounts of market value, estimated marketing costs and estimated legal expenses. Impaired loans secured by real estate, receivables or inventory had discounts determined by management on an individual loan basis. Impaired loans that are not collateral dependent are measured for impairment by a discounted cash flow analysis using a net present value calculation that utilizes data from the loan file before and after the modification.

Foreclosed assets are measured at the lower of book or fair value less costs to sell using third party appraisals, listing agreements or sale contracts, which may be adjusted by additional Level 3 inputs, such as discounts of market value, estimated marketing costs and estimated legal expenses. Management may also consider additional adjustments on specific properties due to the age of the appraisal, expected holding period, lack of comparable sales, or if the other real estate owned is a special use property. At September 30, 2017, the Company had $43 in residential mortgage loans in the process of foreclosure.

The Credit Risk Management department evaluates the valuations on impaired loans and foreclosed assets at least quarterly. The valuations on impaired loans are reviewed at least quarterly by the Allowance for Loan Loss Committee and are considered in the calculation of the allowance for loan losses. Unobservable inputs, such as discounts to collateral, are monitored and adjusted if market conditions change.

The following methodologies were used to measure the fair value of financial assets and liabilities valued on a recurring basis:

Securities available for sale - The fair values of securities available for sale are determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities' relationship to other benchmark quoted securities (Level 2 inputs).

Residential mortgage loans held for sale - Mortgage loans held for sale, 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. Interest income on mortgage loans held for sale is recognized based on the contractual rates and reflected in interest income on loans held for sale in the consolidated income statement. The Company has no continuing involvement in any residential mortgage loans sold.

Derivative instruments:

Interest rate lock commitments ("IRLCs") - The estimated fair values of IRLCs 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 IRLCs 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 - These 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.

Loan customer counterparty and financial institution counterparty - 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). Please see Note 6 — Derivative Financial Instruments for more information.

ASC 820, “Fair Value Measurements and Disclosures”, establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3: Prices or valuation techniques that require inputs that are both significant and unobservable in the market. These instruments are valued using the best information available, some of which is internally developed, and reflects a reporting entity’s own assumptions about the risk premiums that market participants would generally require and the assumptions they would use.

Derivatives

These financial instruments are not designated as hedging instruments and are used for asset and liability management and commercial customers' financing needs. All derivatives are carried at fair value in either other assets or other liabilities.

IRLCs - In the normal course of business, the Company enters into IRLCs 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.

Forward mortgage-backed securities trades - The Company manages the changes in fair value associated with changes in interest rates related to IRLCs by using forward sold commitments known as forward mortgage-backed securities trades. These instruments are typically entered into at the time the IRLC is made.

Interest rate swaps and caps - These derivative positions relate to transactions in which we enter into an interest rate swap or cap with a customer, while at the same time entering into an offsetting interest rate swap or cap with another financial institution. An interest rate swap transaction allows our customer to effectively convert a variable rate loan to a fixed rate. In connection with each swap, we agree 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, we agree 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. In connection with each interest rate cap, we sell a cap to the customer and agree to pay interest if the underlying index exceeds the strike price defined in the cap agreement.  Simultaneously we purchase a cap with matching terms from another financial institution which agrees to pay us if the underlying index exceeds the strike price.

Share-based Compensation

Effective January 1, 2017, the Company changed the accounting for income taxes upon the vesting of stock options and restricted stock to be in accordance with ASC 718, as modified by Accounting Standards Update ("ASU") 2016-09, Improvements to Employee Share-Based Payment Accounting. Prior to the implementation of ASU 2016-09, the tax effects of income tax deductions in excess of compensation cost (windfalls) were recorded in additional paid-in capital, and the tax effects of compensation cost in excess of income tax deductions (shortfalls) were recorded in additional paid-in capital to the extent of previously recognized windfalls, with the remainder recorded in income tax expense. Under ASU 2016-09, all tax effects of windfalls and shortfalls related to share-based payments are recorded through the income statement.

Compensation cost is recognized for stock options and restricted stock awards based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with time-based vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. For awards with performance-based vesting conditions, compensation cost is recognized when the achievement of the performance condition is considered probable of achievement. If a performance condition is subsequently determined to be improbable of achievement, compensation cost is reversed.

Effect of Newly Issued But Not Yet Effective Accounting Standards

Effect of Newly Issued But Not Yet Effective Accounting Standards

In May 2014, the Financial Accounting Standards Board (the "FASB") issued ASU 2014-09, Revenue from Contracts with Customers. This ASU states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU affects entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which deferred the effective date of ASU 2014-09 for public entities to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Our revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. We have completed our initial evaluation of the impact of ASU 2014-09 on components of our non-interest income and have not found any significant changes to our methodology of recognizing revenue. In the fourth quarter of 2017, we will complete this evaluation and finalize disclosures that will be included in our 2018 financial statements, as required by ASU 2014-09, as we will adopt the standard in the first quarter of 2018 with a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be significant.

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurements of Financial Assets and Financial Liabilities. This ASU requires that all equity investments be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under the equity method of accounting or those that result in consolidation of the investee). This ASU also requires that an entity present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, this ASU eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. For public business entities, this ASU is effective for annual periods beginning after December 15, 2017, and interim periods therein. The adoption of this ASU is not expected to have a significant impact on the Company's financial statements and disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases. This ASU requires lessees to put most leases on their balance sheets but recognize expenses in the income statement in a manner similar to current accounting treatment. This ASU changes the guidance on sale-leaseback transactions, initial direct costs and lease execution costs, and, for lessors, modifies the classification criteria and the accounting for sales-type and direct financing leases. For public business entities, this ASU is effective for annual periods beginning after December 15, 2018, and interim periods therein. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is evaluating the impact of this ASU on its financial statements and disclosures.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. This ASU removes the thresholds that companies apply to measure credit losses on financial instruments measured at amortized cost, such as loans, receivables, and held-to-maturity debt securities. Under current US GAAP, companies generally recognize credit losses when it is probable that the loss has been incurred. This revised guidance will remove all recognition thresholds and will require companies to recognize an allowance for lifetime expected credit losses. Credit losses will be immediately recognized through net income; the amount recognized will be based on the current estimate of contractual cash flows not expected to be collected over the financial asset’s contractual term. ASU 2016-13 also amends the credit loss measurement guidance for available for sale debt securities. For public business entities, this ASU is effective for financial statements issued for fiscal years and for interim periods within those fiscal years beginning after December 15, 2019. The Company is evaluating the impact of this ASU on its financial statements and disclosures.

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. This ASU amends the hedge accounting model to enable entities to better portray their risk management activities in their financial statements, by expanding an entity's ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. This ASU eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Additionally, this ASU also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. For public business entities, this ASU is effective for financial statements issued for fiscal years and for interim periods within those fiscal years beginning after December 15, 2018. The Company is evaluating the impact of this ASU on its financial statements and disclosures.
