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 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, 2014 (“2014 Form 10-K”). Interim results are not necessarily indicative of results for a full year.

On January 1, 2015 (the "Effective Time"), the Company completed its merger (the "Merger") with LegacyTexas Group, Inc., pursuant to the Agreement and Plan of Merger, dated as of November 25, 2013, as amended, by and between the Company and LegacyTexas Group, Inc. (the "Merger Agreement"). At the Effective Time, LegacyTexas Group, Inc. merged into the Company, with the Company as the surviving corporation in the Merger. Immediately following the Effective Time, ViewPoint Bank, N.A., merged with and into LegacyTexas Bank, the wholly-owned subsidiary of LegacyTexas Group, Inc. prior to the Merger, with LegacyTexas Bank surviving the bank merger. At the Effective Time, the Company changed its name from ViewPoint Financial Group, Inc. to LegacyTexas Financial Group, Inc. and changed its ticker symbol on the Nasdaq Global Select Market to LTXB. The financial results reported in these consolidated financial statements for periods prior to the Effective Time only include historical activity of ViewPoint Financial Group, Inc.

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 2014 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 - SHARE TRANSACTIONS

On January 27, 2015, the Company announced the resumption of its existing stock repurchase program. The open-ended stock repurchase program, which commenced in August 2012, allows for the repurchase of up to 1,978,871 shares in the open market and in negotiated transactions, depending on market conditions. Stock repurchases under this program were suspended in November 2013 as a result of the Company's announced acquisition of LegacyTexas Group, Inc., which automatically triggered termination of the Company's then-existing 10b5-1 trading plan with Sandler O'Neill & Partners, LP. At the time the stock repurchase program was suspended, 83,800 shares had been repurchased, leaving 1,895,071 shares available for future repurchases under the program.

Upon completion of the acquisition of LegacyTexas Group, Inc. on January 1, 2015, the Company entered into a new trading plan with Sandler O’Neill & Partners, LP in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, to facilitate repurchases of its common stock pursuant to the above mentioned stock repurchase program. No shares were repurchased in the second or third quarter of 2015. During the first quarter of 2015, 357,950 shares were repurchased and retired at an average price of $22.32.

NOTE 3 - 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 share-based 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 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 ended September 30, 2015 and 2014 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, 2015, 61 securities had unrealized losses, 21 of which had been in an unrealized loss position for over 12 months at September 30, 2015. The Company does not believe these unrealized losses are other-than-temporary and, at September 30, 2015, had 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. All principal and interest payments are being received on time and in full.

Activity in the allowance for loan losses for the three and nine months ended September 30, 2015 and 2014, segregated by portfolio segment and evaluation for impairment, is set forth below. All Warehouse Purchase Program loans are collectively evaluated for impairment and are purchased under several contractual requirements, providing safeguards to the Company. These safeguards include the requirement that our mortgage company customers have a takeout commitment for each loan and multiple investors for purchases. To date, the Company has not experienced a loss on these loans and no allowance for loan losses has been allocated to them. At September 30, 2015 and 2014, the allowance for loan impairment related to purchased credit impaired ("PCI") loans totaled $139 and $182, respectively.

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 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. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data and external economic indicators, which may not yet be 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 classified 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, 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 loan 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.

Impaired loans at September 30, 2015 and December 31, 2014, were as follows ¹:

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 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. Interest received on such loans is accounted for on the cash-basis or cost recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Loans past due over 90 days that were still accruing interest totaled $139 at September 30, 2015 and $612 at December 31, 2014, which consisted entirely of PCI loans. At September 30, 2015, no PCI loans were considered non-performing loans. No Warehouse Purchase Program loans were non-performing at September 30, 2015 or December 31, 2014. Non-performing (nonaccrual) loans were as follows:

	September 30,  2015		December 31, 2014
Commercial real estate	$	13,717	$	6,703

A modified loan 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.

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 consumer loans, credit exposure is monitored by payment history of the loans. Non-performing 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, 2015 and December 31, 2014, was as follows.

NOTE 6 - 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.

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).

The Company elects the fair value option for residential mortgage loans held for sale in accordance with ASC 825. This election allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, “Derivatives and Hedging.” Mortgage loans held for sale, which are sold on a servicing released basis, are valued on a recurring basis using a market approach by utilizing either: (1) 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. At September 30, 2015, loans held for sale had an aggregate fair value of $22,802 and an aggregate outstanding principal balance of $22,365 and were recorded in mortgage loans held for sale in the consolidated balance sheet. There were no mortgage loans held for sale that were 90 days or greater past due or on non-accrual at September 30, 2015. 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.

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (i) the assets have been isolated from the Company, (ii) the transferee has the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) the Company does not maintain effective control over the transferred assets through either (a) an agreement that entitles and obligates the Company to repurchase or redeem them before their maturity or (b) the ability to unilaterally cause the holder to return specific assets.

The Company enters into a variety of derivative instruments as part of its hedging strategy and measures these instruments at fair value on a recurring basis in the balance sheet. The majority of these derivatives 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. In addition, the Company enters into interest rate lock commitments ("IRLCs") with prospective borrowers. These commitments are carried at fair value based on the fair value of the underlying mortgage loans which are based on observable market data. The Company adjusts the outstanding IRLCs with prospective borrowers based on an expectation that it will be exercised and the loan will be funded. IRLCs are recorded in other assets or other liabilities in the consolidated balance sheet. These commitments are classified as Level 2 in the fair value disclosures, as the valuations are based on market observable inputs. Net losses of $82 and net gains of $76 resulting from changes in the fair value of these IRLCs and net losses of $404 and $302, on forward mortgage-backed securities trades were recorded in net gain on sale of mortgage loans during the three and nine months ended September 30, 2015, respectively. These gains and losses were not attributable to credit-specific risk. Please see Note 7 - Derivative Financial Instruments for more information.

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). The fair value of these derivative positions outstanding are included in other assets and other liabilities in the accompanying consolidated balance sheets. Please see Note 7 - Derivative Financial Instruments for more information.

Foreclosed assets- commercial real estate	551

¹Foreclosed assets acquired in the LegacyTexas Group, Inc. acquisition.

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. Foreclosed assets acquired from LegacyTexas Group, Inc. were recorded at their estimated fair value on the acquisition date of January 1, 2015. At September 30, 2015, the Company had $262 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 methods and assumptions used to estimate fair value are as follows:

Estimated fair value is the carrying amount for cash and cash equivalents and accrued interest receivable and payable. The fair values of securities held to maturity 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). For 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. For deposits, FHLB advances and overnight repurchase agreements with depositors, fair value is calculated using the FHLB advance curve to discount cash flows for the estimated life for deposits and according to the contractual repayment schedule for FHLB advances. The fair value of the structured repurchase agreement 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. The fair value of subordinated debt (consisting of trust preferred securities) is based on current market rates on similar debt in the market. It is not practicable to determine the fair value of FHLB and Federal Reserve Bank stock due to restrictions on its transferability. 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.

NOTE 7 - DERIVATIVE FINANCIAL INSTRUMENTS

The Company enters into IRLCs with prospective residential mortgage borrowers whereby the interest rate on the loan is determined prior to funding and the borrowers have locked into that interest rate. These commitments are carried at fair value in accordance with ASC 815, Derivatives and Hedging. The estimated fair values of IRLCs are based on observable market data and are recorded in other assets or other liabilities in the consolidated balance sheets. The Company adjusts the outstanding IRLCs with prospective borrowers based on the expectation that it will be exercised and the loan will be funded. The initial and subsequent changes in the fair value of IRLCs are a component of net gain on sale of mortgage loans.

The Company actively manages the risk profiles of its IRLCs and mortgage loans held for sale on a daily basis. To manage the price risk associated with IRLCs, the Company enters into forward sales of mortgage-backed securities in an amount similar to the portion of the IRLC expected to close, assuming no change in mortgage interest rates. In addition, to manage the interest rate risk associated with mortgage loans held for sale, the Company enters into forward sales of mortgage-backed securities to deliver mortgage loan inventory to investors. The estimated fair values of forward sales of mortgage-backed securities and forward sale commitments are based on quoted market values and are recorded in other assets or other liabilities in the consolidated balance sheets. The initial and subsequent changes in value on forward sales of mortgage-backed securities are a component of net gain on sale of mortgage loans.

The following table provides the outstanding notional balances and fair values of outstanding positions at September 30, 2015 and recorded gains (losses) during the three or nine months ended September 30, 2015. The Company did not have any outstanding derivative positions related to mortgage loans held for sale during the three or nine months ended September 30, 2014.

The Company enters into certain interest rate derivative positions that are not designated as hedging instruments. These derivative positions related to transactions in which we entered 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. In connection with each swap transaction, 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. The transaction allows our customer to effectively convert a variable rate loan to a fixed rate. 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. 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. The Company presents derivative instruments at fair value in other assets and other liabilities in the accompanying consolidated balance sheets.

The notional amounts and estimated fair values of interest rate swap derivative positions outstanding and weighted-average receive and pay interest rates at September 30, 2015 and December 31, 2014 are presented in the following table.

Our credit exposure on interest rate swaps is limited to the net favorable value of all swaps by each counterparty. In some cases, collateral may be required from the counterparties involved if the net value of the swaps exceed a nominal amount considered to be immaterial. 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 $300 at September 30, 2015 and $150 at December 31, 2014, is in excess of our credit exposure. The Company does not offset fair value amounts recognized for derivative instruments and the amounts collected and/or deposited on derivative instruments in its consolidated balance sheets.

NOTE 8 - REPURCHASE AGREEMENTS

At September 30, 2015, the Company had a $25,000 outstanding structured repurchase agreement with Credit Suisse, as well as $46,643 in overnight repurchase agreements with depositors.

Repurchase agreements, or "repos", which are classified as securities transactions, are not insured by the Federal Deposit Insurance Corporation (“FDIC”), are not guaranteed, and may lose value. A repo is an agreement between two parties whereby one party (a bank as counterparty) sells the other (as customer) a security at a specified price with a commitment to buy the security back at a fixed time and price. Maturities can vary from overnight to greater than a year, with the longer-maturity repos commonly referred to as “structured” or “term” repos. Repos are accounted for as collateralized borrowings and are recorded at amounts equal to cash received. The contractual terms of the repo may require the Company to provide additional collateral if the fair value of the securities underlying the borrowing decline during the term of the agreement. Risks associated with repos primarily relate to the risk of default and deterioration of collateral value. Risks of default generally include 1) failure to deliver cash or securities as required under the transaction, 2) failure to provide or return cash or securities as used for margining purposes, 3) breach of representation, and 4) a repudiation of obligations under the agreement.

Repos are generally designed so that if a bank counterparty fails to perform its obligations under the repo, the customer may take possession of the collateral. While counterparty selection and collateral requirements provide the customer some protection, repos remain subject to counterparty risk. If a counterparty defaults, a loss may be realized on the sale of the underlying security to the extent that the proceeds from the sale and accrued interest of the security are less than the resale price provided in the repurchase agreement, including interest. Moreover, should a bank counterparty declare bankruptcy or become insolvent, a customer may incur delays and costs in selling the underlying security or may suffer a loss of principal and interest.

To mitigate this risk to the customer, the Company, as the bank counterparty, marks securities sold under repos to fair value on a daily basis and provides 115% market value protection on overnight repos and 112% market value protection on its structured repo.

The following table gives information about the Company's repurchase agreements at September 30, 2015, including the types of collateral pledged against these repos and the remaining contractual maturity of the agreements.

Subordinated debt: Upon the acquisition of LegacyTexas Group, Inc., the Company acquired $15,000 (15,000 shares with a liquidation amount of $1 per security) of Floating Rate Cumulative Trust Preferred Securities ("TruPS") and $464 of common stock through an unconsolidated subsidiary, Legacy Capital Trust II ("Trust II"). Trust II invested the total proceeds from the sale of the TruPS and common stock (totaling $15,464) in floating rate Junior Subordinated Debentures (the "Trust II Debentures") issued by LegacyTexas Group, Inc. The terms of the Trust II Debentures were such that they qualified as Tier I capital under the Federal Reserve Board’s regulatory capital guidelines applicable to bank holding companies. On April 7, 2015, the Company paid this debt in full.

Also upon the acquisition of LegacyTexas Group, Inc., the Company acquired $15,000 (15,000 shares with a liquidation amount of $1 per security) of TruPS and $464 of common stock through an unconsolidated subsidiary, Legacy Capital Trust III ("Trust III").

NOTE 12 - 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 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. Standby letters of credit are written conditional commitments issued by the Company to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment were funded, the Company would seek payment from the customer under pre-arranged terms. The Company's policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements.

The contractual amounts of financial instruments with off‑balance sheet risk at September 30, 2015 and December 31, 2014, 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, 2015		December 31, 2014
Unused commitments to extend credit	$	1,268,504	$	520,659
Unused capacity on Warehouse Purchase Program loans	614,623		414,584
Standby letters of credit	18,808		7,391
Total unused commitments/capacity	$	1,901,935	$	942,634

In addition to the commitments above, the Company had overdraft protection available in the amounts of $87,605 and $73,044 at September 30, 2015 and December 31, 2014, respectively.

In regards 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.

The Company, at September 30, 2015, had FHLB letters of credit of $394,555 pledged to secure public deposits, repurchase agreements, and for other purposes required or permitted by law.

At September 30, 2015, the Company had $3,420 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 13 - RECENT ACCOUNTING DEVELOPMENTS    

In August 2015, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date." This ASU defers the effective date of ASU 2014-09, Revenue from Contracts with Customers, for public entities to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is still evaluating the impact of ASU 2014-09 on its financial statements.

In August 2015, the FASB issued ASU 2015-15, "Interest—Imputation of Interest (Subtopic 835-30), Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements." In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires the presentation of debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 does not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-15 adds SEC paragraphs pursuant to this SEC Staff Announcement at the June 18, 2015, Emerging Issues Task Force meeting about the presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. The Company is evaluating the possible impact of this ASU on its disclosures but does not expect this ASU to have a significant impact on the Company's consolidated statements of income or financial condition.

In September 2015, the FASB issued ASU 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments." To simplify the accounting for adjustments made to provisional amounts recognized in a business combination, this ASU eliminates the requirement to retrospectively account for those adjustments. The ASU requires an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The amendments should be applied prospectively to adjustments to provisional amounts that occur after the effective date with earlier application permitted for financial statements that have not been issued. The adoption of this ASU is not expected to have a significant impact on the Company's financial statements.

NOTE 14 - ACQUISITION

On January 1, 2015, the Company acquired LegacyTexas Group, Inc., a bank holding company and the parent company of LegacyTexas Bank. Immediately following the Merger, the Company amended its articles of incorporation and changed its name to LegacyTexas Financial Group, Inc. Also immediately following the Merger, the Bank merged with and into LegacyTexas Bank and retained the LegacyTexas Bank name.

The Company issued 7,850,070 shares of common stock and paid out $115,150 in cash to LegacyTexas Group, Inc. shareholders in consideration for the Merger.

This business combination was accounted for under the acquisition method of accounting. Under this method of accounting, assets and liabilities acquired are recorded at their estimated fair values. The excess cost over fair value of net assets acquired is recorded as goodwill. As the consideration paid for LegacyTexas Group, Inc. exceeded the provisional value of the net assets acquired, goodwill of $150,982 was recorded related to the Merger. This goodwill resulted from the combination of expected operational synergies and increased market share in the Company's North Texas market area. Goodwill is not tax deductible. The merger also resulted in a core deposit intangible of $880, which is being amortized on an accelerated basis over the estimated life of eight years.

In the second quarter of 2015, management became aware of a misappropriation of approximately $2,450 in vault cash from one of the former LegacyTexas Bank branches it acquired in the Merger.  Upon determining that the misappropriation occurred, management promptly notified law enforcement officials and is cooperating with and assisting them in their investigation of this matter.  Management also engaged a team of independent investigators, including third-party forensic accountants, to conduct an investigation of the matter. The team has informed management of its belief that the misappropriation occurred in all material respects prior to completion of the Merger. Investigations and cooperation with law

enforcement are ongoing. The Company maintains first party liability insurance policies in an amount in excess of the Company’s loss and has notified its carriers.   The claim, however, may not be resolved prior to year-end 2015, and there can be no assurance if or when there will be any recovery. Therefore, the Company reduced the cash acquired through the merger with LegacyTexas Group, Inc. by $2,450 and increased goodwill by $1,592, which is net of tax. This adjustment to goodwill related to cash was partially offset by a $218 (net of tax) reduction to goodwill due to a $336 increase in the valuation of the core deposit intangible.

Fair value: The measurement period for the Company to determine the fair values of acquired identifiable assets and assumed liabilities will end at the earlier of (i) twelve months from the date of the acquisition or (ii) as soon as the Company receives the information it was seeking about facts and circumstances that existed as of the acquisition date or learns that more information is not obtainable. The Company is currently in the process of obtaining fair values for certain acquired assets and assumed liabilities; therefore, the following estimates are preliminary. The following table presents the amounts recorded on the consolidated balance sheet on the acquisition date of January 1, 2015, showing the estimated fair value as reported at March 31, 2015 and the revised estimated fair value at September 30, 2015.

The following pro forma information presents the results of operations for the year ended December 31, 2014, as if the LegacyTexas Group, Inc. acquisition had occurred on January 1, 2014.

	December 31,
	2014
Net interest income	$	204,758
Net income	48,402
Basic earnings per share	1.05
Diluted earnings per share	1.04

The above pro forma results are presented for illustrative purposes and are not intended to represent or be indicative of the actual results of operations of the merged companies that would have been achieved had the Merger occurred on January 1, 2014, nor are they intended to represent or be indicative of future results of operations. The pro forma results do not include expected operating cost savings as a result of the Merger. These pro forma results require significant estimates and judgments, particularly as it relates to valuation and accretion of income associated with acquired loans. Pro forma adjustments included the estimated purchase accounting adjustment on acquired non-impaired loans based on the difference between the fair value and the outstanding principal balance of those loans, recognized over the estimated remaining term of the loans, the estimated purchase accounting adjustment to reflect amortization of the core deposit intangible, as well as the tax effects of these adjustments. Additionally, because LegacyTexas Group, Inc. was a Subchapter S corporation before the Merger, and did not incur any federal income tax liability, an adjustment has been included to estimate the impact of federal income taxes on LegacyTexas Group, Inc.'s net income for the year presented. The tax adjustment was calculated at a 35% tax rate.

Acquired Loans and Purchased Credit Impaired Loans: Acquired loans were preliminarily recorded at fair value based on a discounted cash flow valuation methodology that considers, among other things, projected default rates, loss given defaults and recovery rates. No allowance for credit losses was carried over from LegacyTexas Group, Inc.

The Company has identified certain acquired loans which have experienced credit deterioration since origination (“purchased credit impaired loans” or “PCI” loans). PCI loan identification considers payment history and past due status, debt service coverage, loan grading, collateral values and other factors that may indicate deterioration of credit quality since origination. Accretion of purchase discounts on PCI loans are based on estimated future cash flows, regardless of contractual maturities, that include undiscounted expected principal and interest payments and use credit risk, interest rate and prepayment risk models to incorporate management’s best estimate of current key assumptions such as default rates, loss severity and payment speeds. Accretion of purchase discounts on acquired non-impaired loans will be recognized on a level-yield basis based on contractual maturity of individual loans per ASC 310-20.

The following table discloses the preliminary fair value and contractual value of loans acquired through the merger with LegacyTexas Group, Inc. on January 1, 2015:

	PCI Loans		Acquired Non-Impaired Loans		Total Acquired Loans
Commercial real estate	$	6,176	$	536,314	$	542,490

Special Note Regarding Forward-Looking Statements

When used in filings by LegacyTexas Financial Group, Inc. (the “Company,” the “Registrant,” “we,” or “our” in these financial statements) with the Securities and Exchange Commission (the “SEC”), in the Company's press releases or other public or shareholder communications, and in oral statements made with the approval of an authorized executive officer, the words or phrases “will likely result,” “are expected to,” “will continue,” “is anticipated,” “estimate,” “project,” “intends” or similar expressions are intended to identify “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.

Overview

The Company is a Maryland corporation and LegacyTexas Bank is its wholly owned principal operating subsidiary. On January 1, 2015, LegacyTexas Group, Inc. ("LegacyTexas") merged into the Company and the Company changed its name from ViewPoint Financial Group, Inc. to LegacyTexas Financial Group, Inc. As part of the merger, ViewPoint Bank, N.A., the wholly owned subsidiary of the Company, merged with and into LegacyTexas Bank, the wholly-owned subsidiary of LegacyTexas prior to the merger, with LegacyTexas Bank as the surviving bank. In connection with the Company’s name change, its ticker symbol on the Nasdaq Global Select Market was changed from VPFG to LTXB.

Unless the context otherwise requires, references in this document to the “Company” refer to LegacyTexas Financial Group, Inc. (formerly known as ViewPoint Financial Group, Inc.), and references to the “Bank” include ViewPoint Bank, N.A. which was the Company's wholly owned operating subsidiary prior to January 1, 2015. References to “we,” “us,” and “our” means LegacyTexas Financial Group, Inc. or LegacyTexas Bank, unless the context otherwise requires.

36

Until its merger with LegacyTexas Bank on January 1, 2015, the Bank operated under a national bank charter, with oversight by the Office of the Comptroller of the Currency (“OCC”) and back-up oversight by the FDIC. Effective January 1, 2015, regulators of LegacyTexas Bank are the Texas Department of Banking (“TDOB”) and the Board of Governors of the Federal Reserve System (“FRB”) with back-up oversight by the FDIC. LegacyTexas Bank is required to have certain reserves and stock set by the FRB. LegacyTexas Bank is a member of the Federal Home Loan Bank of Dallas, one of the 12 regional banks in the Federal Home Loan Bank System (“FHLB”). The Company is regulated by the FRB.

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. We also offer brokerage services for the purchase and sale of non-deposit investment and insurance products through a third party brokerage arrangement. 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.

Performance Highlights

• Gross loans held for investment at September 30, 2015, excluding Warehouse Purchase Program loans, grew $2.06 billion, or 78.0%, from December 31, 2014, with $1.00 billion of net growth resulting from loans acquired through the merger with LegacyTexas. Excluding loans acquired through the merger with LegacyTexas, gross loans held for investment, excluding Warehouse Purchase Program loans, increased by $1.05 billion, or 28.9%, from December 31, 2014.

• Warehouse Purchase Program loans at September 30, 2015 totaled $960.4 million, a $174.0 million, or 22.1%, increase from December 31, 2014.

• Net interest margin for the quarter ended September 30, 2015 was 4.00%, a 20 basis point increase compared to the third quarter of 2014, which includes 12 basis points of accretion of interest related to purchase accounting fair value adjustments for the third quarter of 2015.

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 2014 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

37

level of allowance for loan losses in relatively short periods of time. Management believes that the allowance for loan losses is maintained at a level that represents coverage of our best estimate of credit losses in the loan portfolio as of September 30, 2015.

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 loan 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, 2015 and December 31, 2014

General. Total assets increased by $2.71 billion, or 65.2%, to $6.88 billion at September 30, 2015 from $4.16 billion at December 31, 2014, primarily due to the acquisition of LegacyTexas on January 1, 2015, which added $2.05 billion in assets, including $151.0 million in goodwill.

Loans. Gross loans held for investment increased by $2.23 billion, or 65.2%, to $5.65 billion at September 30, 2015 from $3.42 billion at December 31, 2014, while one- to four-family mortgage loans held for sale totaled $22.8 million at September 30, 2015. Prior to the January 1, 2015 merger with LegacyTexas, the Company did not originate for resale or sell mortgage loans to outside investors.

Gross loans held for investment at September 30, 2015, excluding Warehouse Purchase Program loans, grew $2.06 billion, or 78.0%, from December 31, 2014, with $1.00 billion of net growth resulting from loans acquired through the merger with LegacyTexas. Excluding loans acquired through the merger with LegacyTexas and Warehouse Purchase Program loans, gross loans held for investment increased by $1.05 billion, or 28.9%, from December 31, 2014, with increased commercial lending driving the organic growth. Commercial real estate loan balances at September 30, 2015 increased $769.8 million, or 60.8%, from December 31, 2014, with $473.6 million of net growth resulting from the merger with LegacyTexas. Commercial and industrial loans at September 30, 2015 increased $655.4 million, or 83.8%, from December 31, 2014, with $168.7 million of net growth resulting from the merger with LegacyTexas. Construction and land loans at September 30, 2015 increased $239.1 million, or 1,122.8%, from December 31, 2014, with $99.2 million of net growth resulting from the merger with LegacyTexas, while consumer real estate loans increased $356.3 million, or 68.0%, for the same period, which includes $227.2 million of loans acquired through the merger with LegacyTexas. Following the merger with LegacyTexas, the Company now originates one- to four- family real estate loans and sells these loans to outside investors, as well as adding a small portion to the Company's consumer real estate portfolio. Also, the Company originates consumer home equity and home improvement loans.

Energy loans, which are reported as commercial and industrial loans, totaled $431.4 million at September 30, 2015, up $71.8 million from $359.6 million at December 31, 2014, including $4.0 million in energy loans acquired through the merger with LegacyTexas. In May 2013, the Company formed its Energy Finance group, which is comprised of a group of seasoned lenders, executives and credit risk professionals with more than 100 years of combined Texas energy experience, to focus on providing loans to private and public oil and gas companies throughout the United States. The group also offers the Bank's full array of commercial services, including Treasury Management and letters of credit, to its customers. Substantially all of the loans in the Energy portfolio are reserve based loans, secured by deeds of trust on properties containing proven oil and natural gas reserves. Five loans managed by the Energy Finance group are not secured by oil and gas reserves and are reported as commercial and industrial loans (outside of the $431.4 million reported as energy loans). These loans, with a combined commitment of $76.7 million and a total outstanding balance of $31.1 million at September 30, 2015, are categorized as “Midstream and Other” loans. Loans in this category are typically related to the transmission of oil and natural gas and would only be indirectly impacted from declining commodity prices. Please see "Allowance for Loan Losses" for additional information about the credit quality of the energy portfolio.

At September 30, 2015, the Company had eight relationships in the commercial & industrial loan portfolio (outside of the $431.4 million reported as energy loans) 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 the severe drop in the price of oil and gas.  These relationships totaled $6.3 million at September 30, 2015, of which $1.1 million are classified as Substandard.

Warehouse Purchase Program loans increased by $174.0 million, or 22.1%, to $960.4 million at September 30, 2015 from $786.4 million at December 31, 2014. Although not bound by any legally binding commitment, when a purchase decision is made, the Company purchases a 100% participation interest in the loans originated by our mortgage banking company customers, which are then held as one- to four- family mortgage loans. 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 Company to the investor selected by the originator and approved by the Company. Loans funded by the Warehouse Purchase Program during the third quarter of 2015 consisted of 51% conforming and 49% government loans.

Mortgage reform rules mandated by the Dodd-Frank Act became effective in January 2014, requiring lenders to make a reasonable, good faith determination of a borrower’s ability to repay any consumer closed-end credit transaction secured by a dwelling and to limit prepayment penalties. Increased risks of legal challenge, private right of action and regulatory enforcement are presented by these rules. The Company originates and purchases loans that do not meet the definition of a “qualified mortgage” (“QM”). AtSeptember 30, 2015, the Company had $76.8 million in non-QM loans, consisting of home equity and home improvement loans totaling $55.9 million, residential mortgage loans totaling $19.4 million and Warehouse Purchase Program loans totaling $1.5 million. To mitigate the risks involved with non-QM loans, the Company has implemented systems, processes, procedural and product changes, and maintains its underwriting standards, to ensure that the “ability-to-repay” requirements of the new rules are adequately addressed.

Allowance for Loan Losses. The allowance for loan losses is maintained to cover losses that are estimated in accordance with US GAAP. It is our estimate of credit losses 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 5 - "Loans" under Part 1 of this report.

Acquired loans are initially 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 may 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.

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.

39

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. 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 1.42% at September 30, 2015 compared to 0.89% at December 31, 2014. Including Warehouse Purchase Program loans, non-performing loans to total loans held for investment was 1.18% at September 30, 2015 compared to 0.69% at December 31, 2014. Non-performing loans increased by $42.9 million to $66.4 million at September 30, 2015 from $23.5 million at December 31, 2014. This increase was primarily due to three energy loans to two related energy borrowers (classified as commercial and industrial) totaling $36.2 million that were on non-accrual status at September 30, 2015 and were considered impaired; however, the Company does not have any specific reserves set aside and does not currently anticipate any losses on these three loans for the reasons discussed below. $31.0 million of the $36.2 million in non-performing energy loans were placed on non-accrual status during the third quarter of 2015, while $5.2 million was placed on non-accrual in the second quarter of 2015. These energy credits were downgraded as a result of collateral value deterioration due to commodity price declines. As a result of the deterioration, the Company has taken action to improve the risk profile of the criticized energy loans. These actions range from instituting monthly commitment reductions, obtaining additional collateral, obtaining additional guarantor support, and requiring additional equity injections or asset sales.  Borrower response to these actions has been favorable and the Company believes the loans will be paid off or paid down to acceptable risk levels within a reasonable time frame.

Additionally, due to delinquency, a $10.1 million commercial real estate loan secured by a medical facility was placed on non-accrual in the third quarter of 2015. The Company has not set aside any specific reserves for this loan and does not currently anticipate a loss. At September 30, 2015, non-performing loans included $9.0 million in TDRs. For more information about the Company's TDRs, please see Item 1 (Financial Statements) - Note 5 - "Loans" under Part 1 of this report.

Our allowance for loan losses was $36.4 million at September 30, 2015 compared to $25.5 million at December 31, 2014, or 0.64% of total loans held for investment (including Warehouse Purchase Program loans) at September 30, 2015 compared to 0.75% at December 31, 2014. Our allowance for loan losses to total loans held for investment excluding Warehouse Purchase Program loans and loans acquired from LegacyTexas and Highlands was 1.00% at September 30, 2015 compared to 1.00% at December 31, 2014. Our allowance for loan losses to non-performing loans was 54.78% at September 30, 2015 compared to 108.69% at December 31, 2014.

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. The total amount of classified assets represented 13.2% of our total equity and 1.5% of our total assets at September 30, 2015 compared to 9.7% of our total equity and 1.3% of our total assets at December 31, 2014. The aggregate amount of classified assets at the dates indicated was as follows:

	September 30,  2015		December 31,  2014
	(Dollars in thousands)
Doubtful	$	3,884	$	5,576
Substandard	96,284		48,871
Total classified loans	100,168		54,447
Foreclosed assets	4,640		551
Total classified assets	$	104,808	$	54,998

40

Substandard loans at September 30, 2015 increased by $47.4 million from December 31, 2014, which was primarily due to the three energy loans discussed above in Allowance for Loan Losses. Additionally, substandard loans at September 30, 2015 included $8.1 million in loans acquired through the merger with LegacyTexas. The $4.1 million increase in foreclosed assets from December 31, 2014 was due to $4.5 million in other real estate owned acquired through the merger with LegacyTexas.

The Company 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 could 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$21.6 million in loans that were classified as "substandard" but were still accruing interest and were not considered impaired at September 30, 2015 (excluding PCI loans.) Other loans of concern at September 30, 2015 declined by $56.8 million from June 30, 2015, primarily due to $31.0 million in energy loans that moved to non-accrual status in the third quarter of 2015, as well as two energy relationships totaling $19.6 million that paid in full during the third quarter of 2015. (See "Allowance for Loan Losses" for additional information about downgraded energy loans.) Other loans of concern, which were performing at September 30, 2015, have been considered in management's analysis of potential loan losses.

Securities. Our securities portfolio increased $126.4 million, or 28.6%, to $568.1 million at September 30, 2015 from $441.6 million at December 31, 2014. The increase in our securities portfolio primarily resulted from $153.6 million of securities that were acquired through the merger with LegacyTexas. During the nine months ended September 30, 2015, paydowns and maturities of securities totaling $1.04 billion were used to fund loan growth and were partially offset by purchases totaling $1.03 billion. $17.9 million in securities were sold during the nine months ended September 30, 2015, for a gain of $186,000.

Deposits. Total deposits increased $2.11 billion, or 79.5%, to $4.77 billion at September 30, 2015 from $2.66 billion at December 31, 2014, with $1.63 billion of growth resulting from deposits acquired through the merger with LegacyTexas. Excluding deposits acquired through the merger with LegacyTexas, total deposits increased by $482.5 million, or 11.3%, from December 31, 2014.

Savings and money market deposits at September 30, 2015 increased by $806.0 million, or 68.5%, from December 31, 2014, with $534.6 million of growth resulting from deposits acquired through the merger with LegacyTexas. Non-interest-bearing demand deposits increased by $641.9 million, or 129.8%, from December 31, 2014, with $499.7 million of growth resulting from deposits acquired through the merger with LegacyTexas. Interest-bearing demand and time deposits increased by $277.8 million and $386.5 million, respectively, from December 31, 2014; excluding $258.7 million of interest-bearing demand and $336.8 million of time deposits acquired through the merger with LegacyTexas, interest-bearing demand and time deposits increased by $19.1 million and $49.7 million, respectively.

Borrowings. FHLB advances, net of a $616,000 restructuring prepayment penalty, increased $290.0 million, or 33.6%, to $1.15 billion at September 30, 2015 from $862.9 million at December 31, 2014. The outstanding balance of FHLB advances increased due to higher Warehouse Purchase Program balances at September 30, 2015, of which a portion has been strategically funded with short-term advances. At September 30, 2015, the Company was eligible to borrow an additional $542.2 million from the FHLB.

Additionally, the Company has eight available federal funds lines of credit with other financial institutions totaling $250.0 million and was eligible to borrow $39.2 million from the Federal Reserve Bank discount window. In addition to FHLB advances, at September 30, 2015 the Company had a $25.0 million outstanding structured repurchase agreement with Credit Suisse, as well as $46.6 million in overnight repurchase agreements with depositors. Also, at September 30, 2015, subordinated debt consisted of $11.5 million of trust preferred securities that were acquired through the merger with LegacyTexas (reported net of a purchase accounting fair value adjustment of $3.9 million). On April 7, 2015, the Company paid off $15.0 million of TruPS (please see Note 9 - Long-Term Debt of the unaudited interim financial statements provided in this Form 10-Q.)

Shareholders’ Equity. Total shareholders' equity increased by $224.4 million, or 39.5%, to $792.6 million at September 30, 2015 from $568.2 million at December 31, 2014.

The increase in shareholders' equity at September 30, 2015, compared to December 31, 2014, was primarily due to the issuance of 7,850,070 shares representing the stock portion of the merger consideration paid to LegacyTexas shareholders, which increased common stock and additional paid-in capital by a combined $187.2 million. Retained earnings were increased by net income of $54.5 million recognized during the nine months ended September 30, 2015, which was partially offset by the payment of quarterly dividends totaling $0.40 per common share, or $19.1 million, during the nine months ended September 30, 2015.

Comparison of Results of Operations for the Three Months Ended September 30, 2015 and 2014

General. Net income for the three months ended September 30, 2015 was $17.9 million, an increase of $8.6 million, or 92.2%, from net income of $9.3 million for the three months ended September 30, 2014. The increase in net income from the third quarter of 2014 was driven by a $27.2 million increase in interest income on loans and a $6.8 million increase in non-interest income, which was partially offset by a $15.0 million increase in non-interest expense, a $5.0 million increase in the provision for loan losses and a $1.4 million increase in interest expense on deposits. Basic earnings per share for the three months ended September 30, 2015 was $0.39, a $0.15 increase from $0.24 for the three months ended September 30, 2014. Diluted earnings per share for the three months ended September 30, 2015 was $0.38, a $0.14 increase from $0.24 for the three months ended September 30, 2014.

Interest Income. Interest income increased by $27.7 million, or 71.2%, to $66.5 million for the three months ended September 30, 2015 from $38.9 million for the three months ended September 30, 2014.

The $27.7 million increase in interest income compared to the three months ended September 30, 2014 was primarily due to a $27.2 million, or 75.7%, increase in interest income on loans, which was driven by increased volume in all loan categories resulting from loans acquired through the merger with LegacyTexas on January 1, 2015, as well as organic growth. The average balance of commercial real estate loans increased by $805.8 million from the third quarter of 2014, resulting in a $10.3 million increase in interest income. The $805.8 million in growth includes $551.0 million in commercial real estate loans acquired through the merger with LegacyTexas; excluding these loans, the average balance of commercial real estate loans increased by $254.8 million from the third quarter of 2014. The average balance of commercial and industrial loans increased by $677.7 million from the third quarter of 2014, resulting in an $8.1 million increase in interest income. The $677.7 million in growth includes $337.1 million in commercial and industrial loans acquired through the merger with LegacyTexas; excluding these loans, the average balance of commercial and industrial loans increased by $340.6 million from the third quarter of 2014. The average balance of consumer real estate loans increased by $344.9 million from the third quarter of 2014, resulting in a $4.0 million increase in interest income. The $344.9 million in growth includes $264.0 million in consumer real estate loans acquired through the merger with LegacyTexas; excluding these loans, the average balance of consumer real estate loans increased by $80.9 million from the third quarter of 2014. The average balance of Warehouse Purchase Program loans increased by $200.6 million to $845.8 million from the third quarter of 2014, which resulted in a $1.3 million increase in interest income.

Interest income on loans for the third quarter of 2015 included $2.0 million in accretion of purchase accounting fair value adjustments on loans acquired through the merger with LegacyTexas. Accretion of purchase accounting fair value adjustments related to the LegacyTexas acquisition, as well as a smaller amount related to the Highlands Bank acquisition in 2012, contributed 18 basis points, 12 basis points and 22 basis points to the average yields on commercial real estate, commercial and industrial and consumer real estate loans, respectively, for the third quarter of 2015.

Interest Expense. Interest expense increased by $1.2 million, or 27.5%, to $5.3 million for the three months ended September 30, 2015 from $4.2 million for the three months ended September 30, 2014.

The increase in interest expense for the three months ended September 30, 2015 compared to the same period in 2014, was primarily due to an increase in interest expense on deposits, which was driven by increased volume in all deposit categories resulting from deposits acquired through the merger with LegacyTexas on January 1, 2015, as well as organic growth since September 30, 2014. An $875.8 million increase in the average balance of savings and money market deposits to $1.94 billion from the third quarter of 2014 was partially offset by a 12 basis point reduction in the average rate paid on such deposits, resulting in a $96,000 increase in interest expense. The $875.8 million in growth includes $534.6 million in savings and money market deposits acquired through the merger with LegacyTexas; excluding these deposits, the average balance of savings and money market deposits increased by $341.2 million from the third quarter of 2014. The average balance of time deposits increased by $409.3 million to $902.2 million from the third quarter of 2014, resulting in an $808,000 increase in interest expense. The $409.3 million in growth includes $336.8 million in time deposits acquired through the merger with LegacyTexas; excluding these deposits, the average balance of time deposits increased by $72.5 million from the third quarter of 2014. The average balance of interest-bearing demand deposits increased by $276.0 million to $736.1 million from the third quarter of 2014, resulting in a $457,000 increase in interest expense. The $276.0 million in growth includes $258.7 million in interest-bearing demand deposits acquired through the merger with LegacyTexas; excluding these deposits, the average balance of interest-bearing demand deposits increased by $17.3 million from the third quarter of 2014.

The average balance of borrowings increased by $251.1 million compared to the same period in 2014, which was more than offset by a 39 basis point decline in the average rate paid on borrowings, reducing interest expense by $209,000 from the third quarter of 2014.

Net Interest Income. Net interest income increased by $26.5 million, or 76.5%, to $61.2 million for the three months ended September 30, 2015 from $34.7 million for the three months ended September 30, 2014. The net interest margin increased by 20 basis points to 4.00% for the three months ended September 30, 2015 from 3.80% for the same period last year. The net interest rate spread increased by 23 basis points to 3.88% for the three months ended September 30, 2015 from 3.65% for the same period last year. Accretion of interest resulting from the merger with LegacyTexas on January 1, 2015, as well as the 2012 Highlands acquisition, contributed 12 basis points to the net interest margin and average yield on earning assets for the quarter ended September 30, 2015, compared to three basis points for the quarter ended September 30, 2014. The average yield on earning assets for the third quarter of 2015 was 4.35%, a nine basis point increase from the third quarter of 2014. The cost of deposits for the third quarter of 2015 was 0.29%, down four basis points from the third quarter of 2014.

Provision for Loan Losses. The Company recorded a provision for loan losses of $7.5 million for the quarter ended September 30, 2015, compared to $2.5 million for the quarter ended September 30, 2014. The increase in the provision for loan losses compared to the third quarter of 2014 was primarily related to increased organic loan production, as well as loans acquired through the merger with LegacyTexas that were re-underwritten in the normal course of business following completion of the merger. Once an acquired loan undergoes new underwriting and meets the criteria for a new loan, any remaining fair value adjustments are taken into interest income. Without the corresponding fair value adjustment, the newly originated loan drives an increase in the allowance for loan losses. During the third quarter of 2015, the Company added $473.4 million in net loan production that required additional allowance for loan losses, which includes loans acquired through the merger with LegacyTexas that were re-underwritten pursuant to this process.

Net charge-offs for the third quarter of 2015 totaled $2.0 million, an increase of $1.6 million from the third quarter of 2014. This increase was primarily due to a $1.2 million charge-off of a commercial and industrial loan acquired through the merger with LegacyTexas. The $1.2 million charge-off was recorded net of $473,000 in remaining fair value adjustments on the credit.

44

At September 30, 2015, $44.2 million, or 0.94%, of the Company's loan portfolio (excluding Warehouse Purchase Program loans) consisted of criticized energy loans. Of the $44.2 million, three energy loans totaling $36.2 million were on non-accrual status at September 30, 2015 and were considered impaired; however, the Company does not have any specific reserves set aside and does not currently anticipate any losses on these three loans. Please see "Allowance for Loan Losses" for additional information about non-accrual energy loans.

Consistent with prior quarters, during the third quarter of 2015, the Company increased qualitative reserve factors to provide for additional allowance for loan losses due to the continued economic uncertainty in Texas related to the further decline in the price of oil. To date, the Company has not recognized a loss from loans in the Energy portfolio, which we believe is a reflection of prudent risk mitigation techniques.  These techniques include sound underwriting (reasonable advance rates based on number and diversification of wells), sound policy (requiring hedges on production sales) and conservative collateral valuations (frequent borrowing base determinations at prices below NYMEX posted rates).  All borrowing base valuations are performed by experienced and nationally recognized third party firms intimately familiar with the properties and their production history.

Non-interest Income. Non-interest income increased by $6.8 million, or 134.3%, to $11.9 million for the three months ended September 30, 2015 from $5.1 million for the three months ended September 30, 2014.

N/M - not meaningful

The $6.8 million increase in non-interest income from the three months ended September 30, 2014 was primarily due to a $3.4 million increase in service charges and other fees, which was driven by the addition of $1.2 million of title income, as well as increased commercial loan fee income, debit card income and service charges related to accounts acquired through the merger with LegacyTexas. Additionally, the Company recognized $1.9 million in net gains on the sale of mortgage loans during the third quarter of 2015, which includes the gain recognized on $59.5 million of one-to four-family mortgage loans that were sold or committed for sale during the third quarter of 2015, fair value changes on mortgage derivatives and mortgage fees collected. Prior to the January 1, 2015 merger with LegacyTexas, the Company did not originate for resale or sell mortgage loans to outside investors; therefore, a comparable gain was not recorded in the third quarter of 2014. Other non-interest income increased by $887,000 from the third quarter of 2014, primarily due to $695,000 of insurance income added through the acquisition of LegacyTexas.

Non-interest Expense. Non-interest expense increased by $15.0 million, or 66.0%, to $37.8 million for the three months ended September 30, 2015 from $22.8 million for the three months ended September 30, 2014.

The increase in non-interest expense from the three months ended September 30, 2014 was driven by a $10.0 million increase in salaries and employee benefits expense, primarily due to the addition of employees and grants of share-based compensation related to the merger with LegacyTexas. The merger with LegacyTexas also resulted in a $1.8 million increase in occupancy and equipment expense, a $1.3 million increase in office operations expense and a $1.1 million increase in data processing expense for the quarter ended September 30, 2015, compared to the same quarter in 2014. These increases in non-interest expense from the three months ended September 30, 2014 were partially offset by a $1.2 million decrease in merger and acquisition costs related to the merger with LegacyTexas.

Income Tax Expense. For the three months ended September 30, 2015 we recognized income tax expense of $9.8 million on our pre-tax income, compared to income tax expense of $5.1 million for the three months ended September 30, 2014. Both the 2015 and 2014 periods had an effective tax rate of 35.4%.

Comparison of Results of Operations for the Nine Months EndedSeptember 30, 2015 and 2014

General. Net income for the nine months ended September 30, 2015 was $54.5 million, an increase of $28.7 million, or 111.0%, from net income of $25.8 million for the nine months ended September 30, 2014. The increase in net income was driven by an $80.2 million increase in net interest income and an increase in non-interest income of $17.8 million, which was partially offset by a $10.2 million increase in the provision for loan losses and a $44.2 million increase in non-interest expense. Basic earnings per share for the nine months ended September 30, 2015 was $1.18, an increase of $0.51 from $0.67 for the nine months ended September 30, 2014. Diluted earnings per share for the nine months ended September 30, 2015 was $1.17, an increase of $0.50 from $0.67 for the nine months ended September 30, 2014.

The increase in interest income for the nine months ended September 30, 2015 compared to the same period in 2014, was primarily due to an $82.5 million, or 82.3%, increase in interest income on loans, which was driven by increased volume in all loan categories resulting from the merger with LegacyTexas on January 1, 2015, as well as organic growth since September 30, 2014. The average balance of commercial real estate loans increased by $741.9 million to $1.89 billion from the nine months ended September 30, 2014, resulting in a $27.9 million increase in interest income. The $741.9 million in growth includes $551.0 million in commercial real estate loans acquired through the merger with LegacyTexas.

The $203.6 million in growth includes $198.3 million in construction and land loans acquired through the merger with LegacyTexas. The average balance of Warehouse Purchase Program loans increased by $263.0 million to $818.4 million from the nine months ended September 30, 2014, which resulted in a $5.7 million increase in interest income. Interest income on loans for the nine months ended September 30, 2015 included $7.7 million in accretion of purchase accounting fair value adjustments on loans acquired through the merger with LegacyTexas.

Interest Expense. Interest expense increased by $3.3 million, or 26.3%, to $15.8 million for the nine months ended September 30, 2015 from $12.5 million for the nine months ended September 30, 2014.

The increase in interest expense for the nine months ended September 30, 2015 compared to the same period in 2014, was primarily due to increased volume in all deposit categories resulting from deposits acquired through the merger with LegacyTexas on January 1, 2015, as well as organic growth since September 30, 2014 in savings, money market and time deposit balances. An $857.6 million increase in the average balance of savings and money market deposits to $1.85 billion from the nine months ended September 30, 2014 was partially offset by an 11 basis point reduction in the average rate, resulting in a $468,000 increase in interest expense. The $857.6 million in growth includes $534.6 million in savings and money market deposits acquired through the merger with LegacyTexas. The average balance of time deposits increased by $357.9 million to $854.2 million from the nine months ended September 30, 2014, resulting in a $1.9 million increase in interest expense.

balance of interest-bearing demand deposits increased by $250.4 million to $713.5 million from the nine months ended September 30, 2014, resulting in a $1.2 million increase in interest expense. The $250.4 million in growth includes $258.7 million in interest-bearing demand deposits acquired through the merger with LegacyTexas.

The average balance of borrowings increased by $366.8 million compared to the same period in 2014, which was more than offset by a 54 basis point decline in the average rate paid on borrowings, reducing interest expense by $227,000 from the nine months ended September 30, 2014.

Net Interest Income. Net interest income increased by $80.2 million, or 82.5%, to $177.3 million for the nine months ended September 30, 2015 from $97.2 million for the nine months ended September 30, 2014.

The net interest rate spread increased by 31 basis points to 3.91% for the nine months ended September 30, 2015 from 3.60% for the same period last year. The average yield on earning assets for the nine months ended September 30, 2015 was 4.39%, a 14 basis point increase from the nine months ended September 30, 2014, which was primarily due to increased volume in higher-yielding commercial loans, as well as accretion income resulting from the merger with LegacyTexas. The average cost of interest-bearing liabilities for the nine months ended September 30, 2015 was 0.48%, down 17 basis points from the nine months ended September 30, 2014.

Provision for Loan Losses. The provision for loan losses was $14.3 million for the nine months ended September 30, 2015, an increase of $10.2 million from $4.1 million for the nine months ended September 30, 2014. The increase in the provision for loan losses compared to the nine months ended September 30, 2014 was primarily related to increased organic loan production, as well as loans acquired through the merger with LegacyTexas that were re-underwritten in the normal course of business following completion of the merger with LegacyTexas.

Net charge-offs for nine months ended September 30, 2015 totaled $3.4 million, an increase of $2.6 million from the nine months ended September 30, 2014. This increase was primarily due to a $1.2 million charge-off of a commercial and industrial loan acquired through the merger with LegacyTexas. The $1.2 million charge-off was recorded net of $473,000 in remaining fair value adjustments on the credit.

Non-interest Income. Non-interest income increased by $17.8 million, or 115.0%, to $33.2 million for the nine months ended September 30, 2015 from $15.4 million for the nine months ended September 30, 2014.

The increase in non-interest income from the nine months ended September 30, 2014 was primarily due to an $8.5 million increase in service charges and other fees, which was driven by an $849,000 increase in commercial loan fee income, as well as growth in service charges related to accounts acquired through the merger with LegacyTexas, higher Warehouse Purchase Program fee income due to increased volume in that loan portfolio and the addition of $3.4 million of title income through the acquisition of LegacyTexas' title subsidiary. Additionally, the Company recognized $6.1 million in net gains on the sale of mortgage loans during the nine months ended September 30, 2015, which includes the gain recognized on$175.5

million of one-to four-family mortgage loans that were sold or committed for sale during the nine months ended September 30 2015, fair value changes on mortgage derivatives and mortgage fees collected. Prior to the merger with LegacyTexas, the Company did not originate for resale or sell mortgage loans to outside investors; therefore, a comparable gain was not recorded inthe 2014 period. Other non-interest income for the nine months ended September 30, 2015 included $2.1 million of insurance income added through the acquisition of LegacyTexas.

Non-interest Expense. Non-interest expense increased by $44.2 million, or 64.7%, to $112.5 million for the nine months ended September 30, 2015 from $68.3 million for the nine months ended September 30, 2014.

The increase in non-interest expense from the nine months ended September 30, 2014 was driven by a $27.2 million, or 65.0%, increase in salaries and employee benefits expense, primarily due to an increase in full-time equivalent employees to 831 at September 30, 2015, from 512 at September 30, 2014, largely related to the merger with LegacyTexas. Additionally, shortly following the completion of the LegacyTexas merger, certain senior managers from LegacyTexas who joined the Company received immediately-vested stock awards, which resulted in $590,000 of share-based compensation expense recognized during the nine months ended September 30, 2015. Compared to the nine months ended September 30, 2014, occupancy and equipment expense increased by $5.8 million, or 104.2%, and office operations expense increased by $3.0 million, or 59.7%, primarily due to the addition of LegacyTexas' facilities. Data processing expense increased by $3.1 million, or 59.8%, from the comparable 2014 period, as the Company added LegacyTexas into their information technology infrastructure and upgraded various systems to enhance customer service and increase efficiency.

Income Tax Expense. For the nine months ended September 30, 2015 we recognized income tax expense of $29.3 million on our pre-tax income, which was an effective tax rate of 35.0%, compared to income tax expense of $14.4 million for the nine months ended September 30, 2014, which was an effective tax rate of 35.9%. The decrease in the effective tax rate was primarily due to non-deductible merger costs associated with the merger with LegacyTexas recognized in 2014, as well as increased amounts of tax-exempt income on municipal securities and bank-owned life insurance in 2015.

Rate/Volume Analysis

The following tables 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 sources in order to meet its potential liquidity demands. The primary sources are increases in deposit accounts and cash flows from loan payments and the securities portfolio.

In addition to the primary sources of funds, management has several secondary sources available to meet potential funding requirements. At September 30, 2015, the Company had an additional borrowing capacity of $542.2 million with the FHLB. Also, at September 30, 2015, the Company had $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, 2015, securities pledged had a collateral value of $39.2 million.

At September 30, 2015, the Company had classified 56.0% 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 $5.3 million on an unconsolidated basis at September 30, 2015. In addition to its operating expenses, the Company is responsible for paying any dividends declared to its shareholders as well as for any Company stock repurchases. 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 18 of the Notes to Consolidated Financial Statements contained in Item 8 of the Company's 2014 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 $1.90 billion and $942.6 million at September 30, 2015, and December 31, 2014, 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, 2015 totaled $612.0 million with a weighted average rate of 0.18%.

During the nine months ended September 30, 2015, cash and cash equivalents increased by $109.7 million, or 83.1%, to $241.7 million at September 30, 2015 from $132.0 million at December 31, 2014. Operating activities provided cash of $88.6 million and financing activities provided cash of $703.7 million, which was partially offset by cash used in investing activities of $682.7 million. Primary sources of cash for the nine months ended September 30, 2015 included proceeds from pay-offs of Warehouse Purchase Program loans totaling $11.76 billion and proceeds from FHLB advances of $1.04 billion. Primary uses of cash for the nine months ended September 30, 2015 included originations of Warehouse Purchase Program

54

loans totaling $11.93 billion, repayments on FHLB advances of $750.0 million and net fundings of loans held for investment totaling $651.1 million.

Please see Item 1A (Risk Factors) under Part 1 of the Company's 2014 Form 10-K for information regarding liquidity risk.

Capital Resources

At December 31, 2014, the Bank and the Company were subject to minimum capital requirements imposed by the OCC and the FRB. Effective on January 1, 2015, upon completion of the merger with LegacyTexas, the Bank was merged into LegacyTexas Bank, with regulatory oversight by the TDOB and the FRB. 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, 2015 and December 31, 2014, the Bank and the Company were considered to be well-capitalized.

At September 30, 2015, the Bank's equity totaled $776.5 million. The Company's consolidated equity totaled $792.6 million, or 11.5% of total assets, at September 30, 2015. 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, 2015, Warehouse Purchase Program loans totaled $960.4 million, compared to an average balance of $845.8 million for the three months ended September 30, 2015. Because the capital ratios below are calculated using ending risk-weighted assets and Warehouse Purchase Program loans are risk-weighted at 100%, the end of period increase in these balances can significantly impact the Company's reported capital ratios.

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 ("FFEIC") 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, 200, 300, and 400 basis points, the Bank's policy indicates that the change in EVE should not exceed a 15.00% decrease. For an instantaneous, parallel, and sustained interest rate increase or decrease of 100 basis points, the Bank's policy indicates that EAR should not decrease by more than 7%, and for increases of 200, 300, and 400 basis points, EAR should not decrease by more than 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, 2015, and December 31, 2014, 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. As illustrated in the table below, at September 30, 2015, our EAR would be negatively impacted by a parallel, instantaneous, and sustained increase in market rates of 200, 300, or 400 basis points. As market interest rates rise and variable liability rates are modeled to increase faster than assets mature or reprice.

The Bank's EVE was $903.6 million, or 13.37%, of the market value of portfolio assets as of September 30, 2015, a $238.1 millionincrease from $665.5 million, or 15.87%, of the market value of portfolio assets as of December 31, 2014. Based upon the assumptions utilized, an immediate 200 basis point increase in market interest rates would result in a $39.0 million decrease in our EVE at September 30, 2015 compared to a $21.7 million decrease at December 31, 2014, and would

58

result in a 12 basis point decrease in our EVE ratio to 13.25% at September 30, 2015 compared to a seven basis point increase to 15.94% at December 31, 2014. An immediate 100 basis point decrease in market interest rates would result in a $6.5 million decrease in our EVE at September 30, 2015 compared to a $12.4 million increase at December 31, 2014, and would result in a 35 basis point decrease in our EVE ratio to 13.02% at September 30, 2015, as compared to a four basis point decrease in our EVE ratio to 15.83% at December 31, 2014.

The Bank's projected EAR for the twelve months ending September 30,2016 is $249.7 million, compared to $147.3 million for the twelve months ending December 31, 2015. Based on the assumptions utilized, an immediate 200 basis point increase in market rates would result in an $8.1 million, or 3.26%, decrease in net interest income for the twelve months ending September 30,2016 compared to a $4.4 million, or 3.00%, increase for the twelve months ending December 31, 2015. An immediate 100 basis point decrease in market rates would result in a $4.5 million decrease in net interest income for the twelve months ending September 30,2016 compared to a $3.9 million decrease for the twelve months ending December 31, 2015. In May 2015, we increased non-maturity deposit betas utilized in our interest rate risk model. The primary goal is to model anticipated higher sensitivities due to the current prolonged low rate environment and the signaled impending rate rise from the Federal Reserve.

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, 2015. 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 - (Policies)

9 Months Ended

Sep. 30, 2015

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 2014 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.

Securities

Gains and losses on the sale of securities classified as available for sale are recorded on the trade date using the specific-identification method.

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

A modified loan 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 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 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. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data and external economic indicators, which may not yet be 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 classified 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, 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 loan 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.

Loans

For consumer loans, credit exposure is monitored by payment history of the loans. Non-performing 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 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. Interest received on such loans is accounted for on the cash-basis or cost recovery method, until qualifying for return to accrual. 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

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. Foreclosed assets acquired from LegacyTexas Group, Inc. were recorded at their estimated fair value on the acquisition date of January 1, 2015. At September 30, 2015, the Company had $262 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.

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.

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).

The Company elects the fair value option for residential mortgage loans held for sale in accordance with ASC 825. This election allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, “Derivatives and Hedging.” Mortgage loans held for sale, which are sold on a servicing released basis, are valued on a recurring basis using a market approach by utilizing either: (1) 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. At September 30, 2015, loans held for sale had an aggregate fair value of $22,802 and an aggregate outstanding principal balance of $22,365 and were recorded in mortgage loans held for sale in the consolidated balance sheet. There were no mortgage loans held for sale that were 90 days or greater past due or on non-accrual at September 30, 2015. 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.

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (i) the assets have been isolated from the Company, (ii) the transferee has the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) the Company does not maintain effective control over the transferred assets through either (a) an agreement that entitles and obligates the Company to repurchase or redeem them before their maturity or (b) the ability to unilaterally cause the holder to return specific assets.

The Company enters into a variety of derivative instruments as part of its hedging strategy and measures these instruments at fair value on a recurring basis in the balance sheet. The majority of these derivatives 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. In addition, the Company enters into interest rate lock commitments ("IRLCs") with prospective borrowers. These commitments are carried at fair value based on the fair value of the underlying mortgage loans which are based on observable market data. The Company adjusts the outstanding IRLCs with prospective borrowers based on an expectation that it will be exercised and the loan will be funded. IRLCs are recorded in other assets or other liabilities in the consolidated balance sheet. These commitments are classified as Level 2 in the fair value disclosures, as the valuations are based on market observable inputs.

Derivatives

The Company enters into IRLCs with prospective residential mortgage borrowers whereby the interest rate on the loan is determined prior to funding and the borrowers have locked into that interest rate. These commitments are carried at fair value in accordance with ASC 815, Derivatives and Hedging. The estimated fair values of IRLCs are based on observable market data and are recorded in other assets or other liabilities in the consolidated balance sheets. The Company adjusts the outstanding IRLCs with prospective borrowers based on the expectation that it will be exercised and the loan will be funded. The initial and subsequent changes in the fair value of IRLCs are a component of net gain on sale of mortgage loans.

The Company actively manages the risk profiles of its IRLCs and mortgage loans held for sale on a daily basis. To manage the price risk associated with IRLCs, the Company enters into forward sales of mortgage-backed securities in an amount similar to the portion of the IRLC expected to close, assuming no change in mortgage interest rates. In addition, to manage the interest rate risk associated with mortgage loans held for sale, the Company enters into forward sales of mortgage-backed securities to deliver mortgage loan inventory to investors. The estimated fair values of forward sales of mortgage-backed securities and forward sale commitments are based on quoted market values and are recorded in other assets or other liabilities in the consolidated balance sheets. The initial and subsequent changes in value on forward sales of mortgage-backed securities are a component of net gain on sale of mortgage loans.

Repurchase and Resale Agreements

Repurchase agreements, or "repos", which are classified as securities transactions, are not insured by the Federal Deposit Insurance Corporation (“FDIC”), are not guaranteed, and may lose value. A repo is an agreement between two parties whereby one party (a bank as counterparty) sells the other (as customer) a security at a specified price with a commitment to buy the security back at a fixed time and price. Maturities can vary from overnight to greater than a year, with the longer-maturity repos commonly referred to as “structured” or “term” repos. Repos are accounted for as collateralized borrowings and are recorded at amounts equal to cash received. The contractual terms of the repo may require the Company to provide additional collateral if the fair value of the securities underlying the borrowing decline during the term of the agreement. Risks associated with repos primarily relate to the risk of default and deterioration of collateral value. Risks of default generally include 1) failure to deliver cash or securities as required under the transaction, 2) failure to provide or return cash or securities as used for margining purposes, 3) breach of representation, and 4) a repudiation of obligations under the agreement.

Repos are generally designed so that if a bank counterparty fails to perform its obligations under the repo, the customer may take possession of the collateral. While counterparty selection and collateral requirements provide the customer some protection, repos remain subject to counterparty risk. If a counterparty defaults, a loss may be realized on the sale of the underlying security to the extent that the proceeds from the sale and accrued interest of the security are less than the resale price provided in the repurchase agreement, including interest. Moreover, should a bank counterparty declare bankruptcy or become insolvent, a customer may incur delays and costs in selling the underlying security or may suffer a loss of principal and interest.

To mitigate this risk to the customer, the Company, as the bank counterparty, marks securities sold under repos to fair value on a daily basis and provides 115% market value protection on overnight repos and 112% market value protection on its structured repo.

Recent Accounting Developments

In August 2015, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date." This ASU defers the effective date of ASU 2014-09, Revenue from Contracts with Customers, for public entities to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is still evaluating the impact of ASU 2014-09 on its financial statements.

In August 2015, the FASB issued ASU 2015-15, "Interest—Imputation of Interest (Subtopic 835-30), Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements." In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires the presentation of debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 does not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-15 adds SEC paragraphs pursuant to this SEC Staff Announcement at the June 18, 2015, Emerging Issues Task Force meeting about the presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. The Company is evaluating the possible impact of this ASU on its disclosures but does not expect this ASU to have a significant impact on the Company's consolidated statements of income or financial condition.

In September 2015, the FASB issued ASU 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments." To simplify the accounting for adjustments made to provisional amounts recognized in a business combination, this ASU eliminates the requirement to retrospectively account for those adjustments. The ASU requires an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The amendments should be applied prospectively to adjustments to provisional amounts that occur after the effective date with earlier application permitted for financial statements that have not been issued. The adoption of this ASU is not expected to have a significant impact on the Company's financial statements.

Allowance for Loan Losses

Activity in the allowance for loan losses for the three and nine months ended September 30, 2015 and 2014, segregated by portfolio segment and evaluation for impairment, is set forth below. All Warehouse Purchase Program loans are collectively evaluated for impairment and are purchased under several contractual requirements, providing safeguards to the Company. These safeguards include the requirement that our mortgage company customers have a takeout commitment for each loan and multiple investors for purchases. To date, the Company has not experienced a loss on these loans and no allowance for loan losses has been allocated to them. At September 30, 2015 and 2014, the allowance for loan impairment related to purchased credit impaired ("PCI") loans totaled $139 and $182, respectively.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

RECENT ACCOUNTING DEVELOPMENTS

RECENT ACCOUNTING DEVELOPMENTS    

In August 2015, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date." This ASU defers the effective date of ASU 2014-09, Revenue from Contracts with Customers, for public entities to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is still evaluating the impact of ASU 2014-09 on its financial statements.

In August 2015, the FASB issued ASU 2015-15, "Interest—Imputation of Interest (Subtopic 835-30), Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements." In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires the presentation of debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 does not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-15 adds SEC paragraphs pursuant to this SEC Staff Announcement at the June 18, 2015, Emerging Issues Task Force meeting about the presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. The Company is evaluating the possible impact of this ASU on its disclosures but does not expect this ASU to have a significant impact on the Company's consolidated statements of income or financial condition.

In September 2015, the FASB issued ASU 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments." To simplify the accounting for adjustments made to provisional amounts recognized in a business combination, this ASU eliminates the requirement to retrospectively account for those adjustments. The ASU requires an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The amendments should be applied prospectively to adjustments to provisional amounts that occur after the effective date with earlier application permitted for financial statements that have not been issued. The adoption of this ASU is not expected to have a significant impact on the Company's financial statements.

REPURCHASE AGREEMENTS

REPURCHASE AGREEMENTS

REPURCHASE AGREEMENTS

At September 30, 2015, the Company had a $25,000 outstanding structured repurchase agreement with Credit Suisse, as well as $46,643 in overnight repurchase agreements with depositors.

Repurchase agreements, or "repos", which are classified as securities transactions, are not insured by the Federal Deposit Insurance Corporation (“FDIC”), are not guaranteed, and may lose value. A repo is an agreement between two parties whereby one party (a bank as counterparty) sells the other (as customer) a security at a specified price with a commitment to buy the security back at a fixed time and price. Maturities can vary from overnight to greater than a year, with the longer-maturity repos commonly referred to as “structured” or “term” repos. Repos are accounted for as collateralized borrowings and are recorded at amounts equal to cash received. The contractual terms of the repo may require the Company to provide additional collateral if the fair value of the securities underlying the borrowing decline during the term of the agreement. Risks associated with repos primarily relate to the risk of default and deterioration of collateral value. Risks of default generally include 1) failure to deliver cash or securities as required under the transaction, 2) failure to provide or return cash or securities as used for margining purposes, 3) breach of representation, and 4) a repudiation of obligations under the agreement.

Repos are generally designed so that if a bank counterparty fails to perform its obligations under the repo, the customer may take possession of the collateral. While counterparty selection and collateral requirements provide the customer some protection, repos remain subject to counterparty risk. If a counterparty defaults, a loss may be realized on the sale of the underlying security to the extent that the proceeds from the sale and accrued interest of the security are less than the resale price provided in the repurchase agreement, including interest. Moreover, should a bank counterparty declare bankruptcy or become insolvent, a customer may incur delays and costs in selling the underlying security or may suffer a loss of principal and interest.

To mitigate this risk to the customer, the Company, as the bank counterparty, marks securities sold under repos to fair value on a daily basis and provides 115% market value protection on overnight repos and 112% market value protection on its structured repo.

The following table gives information about the Company's repurchase agreements at September 30, 2015, including the types of collateral pledged against these repos and the remaining contractual maturity of the agreements.

LONG-TERM DEBT

Subordinated debt: Upon the acquisition of LegacyTexas Group, Inc., the Company acquired $15,000 (15,000 shares with a liquidation amount of $1 per security) of Floating Rate Cumulative Trust Preferred Securities ("TruPS") and $464 of common stock through an unconsolidated subsidiary, Legacy Capital Trust II ("Trust II"). Trust II invested the total proceeds from the sale of the TruPS and common stock (totaling $15,464) in floating rate Junior Subordinated Debentures (the "Trust II Debentures") issued by LegacyTexas Group, Inc. The terms of the Trust II Debentures were such that they qualified as Tier I capital under the Federal Reserve Board’s regulatory capital guidelines applicable to bank holding companies.

EARNINGS PER COMMON SHARE

9 Months Ended

Sep. 30, 2015

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 share-based 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 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 ended September 30, 2015 and 2014 is as follows:

SHARE TRANSACTIONS

SHARE TRANSACTIONS

On January 27, 2015, the Company announced the resumption of its existing stock repurchase program. The open-ended stock repurchase program, which commenced in August 2012, allows for the repurchase of up to 1,978,871 shares in the open market and in negotiated transactions, depending on market conditions. Stock repurchases under this program were suspended in November 2013 as a result of the Company's announced acquisition of LegacyTexas Group, Inc., which automatically triggered termination of the Company's then-existing 10b5-1 trading plan with Sandler O'Neill & Partners, LP. At the time the stock repurchase program was suspended, 83,800 shares had been repurchased, leaving 1,895,071 shares available for future repurchases under the program.

Upon completion of the acquisition of LegacyTexas Group, Inc. on January 1, 2015, the Company entered into a new trading plan with Sandler O’Neill & Partners, LP in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, to facilitate repurchases of its common stock pursuant to the above mentioned stock repurchase program. No shares were repurchased in the second or third quarter of 2015. During the first quarter of 2015, 357,950 shares were repurchased and retired at an average price of $22.32.

Business Combinations [Abstract]

ACQUISITION

ACQUISITION

On January 1, 2015, the Company acquired LegacyTexas Group, Inc., a bank holding company and the parent company of LegacyTexas Bank. Immediately following the Merger, the Company amended its articles of incorporation and changed its name to LegacyTexas Financial Group, Inc. Also immediately following the Merger, the Bank merged with and into LegacyTexas Bank and retained the LegacyTexas Bank name.

The Company issued 7,850,070 shares of common stock and paid out $115,150 in cash to LegacyTexas Group, Inc. shareholders in consideration for the Merger.

This business combination was accounted for under the acquisition method of accounting. Under this method of accounting, assets and liabilities acquired are recorded at their estimated fair values. The excess cost over fair value of net assets acquired is recorded as goodwill. As the consideration paid for LegacyTexas Group, Inc. exceeded the provisional value of the net assets acquired, goodwill of $150,982 was recorded related to the Merger. This goodwill resulted from the combination of expected operational synergies and increased market share in the Company's North Texas market area. Goodwill is not tax deductible. The merger also resulted in a core deposit intangible of $880, which is being amortized on an accelerated basis over the estimated life of eight years.

In the second quarter of 2015, management became aware of a misappropriation of approximately $2,450 in vault cash from one of the former LegacyTexas Bank branches it acquired in the Merger.  Upon determining that the misappropriation occurred, management promptly notified law enforcement officials and is cooperating with and assisting them in their investigation of this matter.  Management also engaged a team of independent investigators, including third-party forensic accountants, to conduct an investigation of the matter. The team has informed management of its belief that the misappropriation occurred in all material respects prior to completion of the Merger. Investigations and cooperation with law enforcement are ongoing. The Company maintains first party liability insurance policies in an amount in excess of the Company’s loss and has notified its carriers.   The claim, however, may not be resolved prior to year-end 2015, and there can be no assurance if or when there will be any recovery. Therefore, the Company reduced the cash acquired through the merger with LegacyTexas Group, Inc. by $2,450 and increased goodwill by $1,592, which is net of tax. This adjustment to goodwill related to cash was partially offset by a $218 (net of tax) reduction to goodwill due to a $336 increase in the valuation of the core deposit intangible.

Fair value: The measurement period for the Company to determine the fair values of acquired identifiable assets and assumed liabilities will end at the earlier of (i) twelve months from the date of the acquisition or (ii) as soon as the Company receives the information it was seeking about facts and circumstances that existed as of the acquisition date or learns that more information is not obtainable. The Company is currently in the process of obtaining fair values for certain acquired assets and assumed liabilities; therefore, the following estimates are preliminary. The following table presents the amounts recorded on the consolidated balance sheet on the acquisition date of January 1, 2015, showing the estimated fair value as reported at March 31, 2015 and the revised estimated fair value at September 30, 2015.

Merger-related expenses and pro forma information: The below table presents pre-tax merger and acquisition expenses incurred by the Company related the Merger. Merger and acquisition expenses are reflected on the Company's income statement for the applicable periods in non-interest expense.

The following pro forma information presents the results of operations for the year ended December 31, 2014, as if the LegacyTexas Group, Inc. acquisition had occurred on January 1, 2014.

The above pro forma results are presented for illustrative purposes and are not intended to represent or be indicative of the actual results of operations of the merged companies that would have been achieved had the Merger occurred on January 1, 2014, nor are they intended to represent or be indicative of future results of operations. The pro forma results do not include expected operating cost savings as a result of the Merger. These pro forma results require significant estimates and judgments, particularly as it relates to valuation and accretion of income associated with acquired loans. Pro forma adjustments included the estimated purchase accounting adjustment on acquired non-impaired loans based on the difference between the fair value and the outstanding principal balance of those loans, recognized over the estimated remaining term of the loans, the estimated purchase accounting adjustment to reflect amortization of the core deposit intangible, as well as the tax effects of these adjustments. Additionally, because LegacyTexas Group, Inc. was a Subchapter S corporation before the Merger, and did not incur any federal income tax liability, an adjustment has been included to estimate the impact of federal income taxes on LegacyTexas Group, Inc.'s net income for the year presented. The tax adjustment was calculated at a 35% tax rate.

Acquired Loans and Purchased Credit Impaired Loans: Acquired loans were preliminarily recorded at fair value based on a discounted cash flow valuation methodology that considers, among other things, projected default rates, loss given defaults and recovery rates. No allowance for credit losses was carried over from LegacyTexas Group, Inc.

The Company has identified certain acquired loans which have experienced credit deterioration since origination (“purchased credit impaired loans” or “PCI” loans). PCI loan identification considers payment history and past due status, debt service coverage, loan grading, collateral values and other factors that may indicate deterioration of credit quality since origination. Accretion of purchase discounts on PCI loans are based on estimated future cash flows, regardless of contractual maturities, that include undiscounted expected principal and interest payments and use credit risk, interest rate and prepayment risk models to incorporate management’s best estimate of current key assumptions such as default rates, loss severity and payment speeds. Accretion of purchase discounts on acquired non-impaired loans will be recognized on a level-yield basis based on contractual maturity of individual loans per ASC 310-20.

The following table discloses the preliminary fair value and contractual value of loans acquired through the merger with LegacyTexas Group, Inc. on January 1, 2015:

	PCI Loans		Acquired Non-Impaired Loans		Total Acquired Loans
Commercial real estate	$	6,176	$	536,314	$	542,490

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.

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).

The Company elects the fair value option for residential mortgage loans held for sale in accordance with ASC 825. This election allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, “Derivatives and Hedging.” Mortgage loans held for sale, which are sold on a servicing released basis, are valued on a recurring basis using a market approach by utilizing either: (1) 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. At September 30, 2015, loans held for sale had an aggregate fair value of $22,802 and an aggregate outstanding principal balance of $22,365 and were recorded in mortgage loans held for sale in the consolidated balance sheet. There were no mortgage loans held for sale that were 90 days or greater past due or on non-accrual at September 30, 2015. 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.

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (i) the assets have been isolated from the Company, (ii) the transferee has the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) the Company does not maintain effective control over the transferred assets through either (a) an agreement that entitles and obligates the Company to repurchase or redeem them before their maturity or (b) the ability to unilaterally cause the holder to return specific assets.

The Company enters into a variety of derivative instruments as part of its hedging strategy and measures these instruments at fair value on a recurring basis in the balance sheet. The majority of these derivatives 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. In addition, the Company enters into interest rate lock commitments ("IRLCs") with prospective borrowers. These commitments are carried at fair value based on the fair value of the underlying mortgage loans which are based on observable market data. The Company adjusts the outstanding IRLCs with prospective borrowers based on an expectation that it will be exercised and the loan will be funded. IRLCs are recorded in other assets or other liabilities in the consolidated balance sheet. These commitments are classified as Level 2 in the fair value disclosures, as the valuations are based on market observable inputs. Net losses of $82 and net gains of $76 resulting from changes in the fair value of these IRLCs and net losses of $404 and $302, on forward mortgage-backed securities trades were recorded in net gain on sale of mortgage loans during the three and nine months ended September 30, 2015, respectively. These gains and losses were not attributable to credit-specific risk. Please see Note 7 - Derivative Financial Instruments for more information.

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). The fair value of these derivative positions outstanding are included in other assets and other liabilities in the accompanying consolidated balance sheets. Please see Note 7 - Derivative Financial Instruments for more information.

Assets:
Impaired loans	$	5,323
Foreclosed assets- commercial real estate	551

¹Foreclosed assets acquired in the LegacyTexas Group, Inc. acquisition.

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. Foreclosed assets acquired from LegacyTexas Group, Inc. were recorded at their estimated fair value on the acquisition date of January 1, 2015. At September 30, 2015, the Company had $262 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 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, 2015 and at December 31, 2014, were as follows:

The methods and assumptions used to estimate fair value are as follows:

Estimated fair value is the carrying amount for cash and cash equivalents and accrued interest receivable and payable. The fair values of securities held to maturity 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). For 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. For deposits, FHLB advances and overnight repurchase agreements with depositors, fair value is calculated using the FHLB advance curve to discount cash flows for the estimated life for deposits and according to the contractual repayment schedule for FHLB advances. The fair value of the structured repurchase agreement 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. The fair value of subordinated debt (consisting of trust preferred securities) is based on current market rates on similar debt in the market. It is not practicable to determine the fair value of FHLB and Federal Reserve Bank stock due to restrictions on its transferability. 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.

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, 2015, 61 securities had unrealized losses, 21 of which had been in an unrealized loss position for over 12 months at September 30, 2015. The Company does not believe these unrealized losses are other-than-temporary and, at September 30, 2015, had 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. All principal and interest payments are being received on time and in full.

Activity in the allowance for loan losses for the three and nine months ended September 30, 2015 and 2014, segregated by portfolio segment and evaluation for impairment, is set forth below. All Warehouse Purchase Program loans are collectively evaluated for impairment and are purchased under several contractual requirements, providing safeguards to the Company. These safeguards include the requirement that our mortgage company customers have a takeout commitment for each loan and multiple investors for purchases. To date, the Company has not experienced a loss on these loans and no allowance for loan losses has been allocated to them. At September 30, 2015 and 2014, the allowance for loan impairment related to purchased credit impaired ("PCI") loans totaled $139 and $182, respectively.

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 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. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data and external economic indicators, which may not yet be 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 classified 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, 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 loan 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.

Impaired loans at September 30, 2015 and December 31, 2014, were as follows ¹:

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 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. Interest received on such loans is accounted for on the cash-basis or cost recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Loans past due over 90 days that were still accruing interest totaled $139 at September 30, 2015 and $612 at December 31, 2014, which consisted entirely of PCI loans. At September 30, 2015, no PCI loans were considered non-performing loans. No Warehouse Purchase Program loans were non-performing at September 30, 2015 or December 31, 2014. Non-performing (nonaccrual) loans were as follows:

	September 30,  2015		December 31, 2014
Commercial real estate	$	13,717	$	6,703
Commercial and industrial	41,538		5,778

Consumer real estate	10,894		10,591

A modified loan 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, 2015		December 31, 2014
Nonaccrual TDRs(1)	$	8,961	$	12,982

Loans acquired with evidence of credit quality deterioration at acquisition, for which it was probable that the Company would not be able to collect all contractual amounts due, were accounted for as PCI loans. The carrying amount of PCI loans included in the consolidated balance sheets and the related outstanding balances at September 30, 2015 and December 31, 2014 were as follows. The outstanding balance represents the total amount owed, including accrued but unpaid interest, and any amounts previously charged off.

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 consumer loans, credit exposure is monitored by payment history of the loans. Non-performing 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, 2015 and December 31, 2014, was as follows.

DERIVATIVE FINANCIAL INSTRUMENTS

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE FINANCIAL INSTRUMENTS

DERIVATIVE FINANCIAL INSTRUMENTS

The Company enters into IRLCs with prospective residential mortgage borrowers whereby the interest rate on the loan is determined prior to funding and the borrowers have locked into that interest rate. These commitments are carried at fair value in accordance with ASC 815, Derivatives and Hedging. The estimated fair values of IRLCs are based on observable market data and are recorded in other assets or other liabilities in the consolidated balance sheets. The Company adjusts the outstanding IRLCs with prospective borrowers based on the expectation that it will be exercised and the loan will be funded. The initial and subsequent changes in the fair value of IRLCs are a component of net gain on sale of mortgage loans.

The Company actively manages the risk profiles of its IRLCs and mortgage loans held for sale on a daily basis. To manage the price risk associated with IRLCs, the Company enters into forward sales of mortgage-backed securities in an amount similar to the portion of the IRLC expected to close, assuming no change in mortgage interest rates. In addition, to manage the interest rate risk associated with mortgage loans held for sale, the Company enters into forward sales of mortgage-backed securities to deliver mortgage loan inventory to investors. The estimated fair values of forward sales of mortgage-backed securities and forward sale commitments are based on quoted market values and are recorded in other assets or other liabilities in the consolidated balance sheets. The initial and subsequent changes in value on forward sales of mortgage-backed securities are a component of net gain on sale of mortgage loans.

The following table provides the outstanding notional balances and fair values of outstanding positions at September 30, 2015 and recorded gains (losses) during the three or nine months ended September 30, 2015. The Company did not have any outstanding derivative positions related to mortgage loans held for sale during the three or nine months ended September 30, 2014.

							Recorded Gains/(Losses)
Derivative Positions related to Mortgage Loans Held for Sale:	Expiration Dates	Outstanding Notional Balance		Fair Value			Three Months Ended September 30, 2015			Nine Months Ended September 30, 2015
IRLCs	2015	$	12,437	$	490		$	(82	)	$	76
Forward mortgage-backed securities trades	2015	21,631		(146		)	(404		)	(302		)

The Company enters into certain interest rate derivative positions that are not designated as hedging instruments. These derivative positions related to transactions in which we entered 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. In connection with each swap transaction, 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. The transaction allows our customer to effectively convert a variable rate loan to a fixed rate. 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. 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. The Company presents derivative instruments at fair value in other assets and other liabilities in the accompanying consolidated balance sheets.

The notional amounts and estimated fair values of interest rate swap derivative positions outstanding and weighted-average receive and pay interest rates at September 30, 2015 and December 31, 2014 are presented in the following table.

Derivative Positions related to Commercial Loan Interest Rate Swaps:	Outstanding Notional Amount			Estimated Fair Value			Weighted-Average Interest Rate
							Received		Paid
September 30, 2015
Loan customer counterparty	$	20,088		$	333		4.28	%	3.23	%
Financial institution counterparty	(20,088		)	(333		)	3.23		4.28
December 31, 2014
Loan customer counterparty	$	6,199		$	64		4.38	%	2.91	%
Financial institution counterparty	(6,199		)	(64		)	2.91		4.38

Our credit exposure on interest rate swaps is limited to the net favorable value of all swaps by each counterparty. In some cases, collateral may be required from the counterparties involved if the net value of the swaps exceed a nominal amount considered to be immaterial. 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 $300 at September 30, 2015 and $150 at December 31, 2014, is in excess of our credit exposure. The Company does not offset fair value amounts recognized for derivative instruments and the amounts collected and/or deposited on derivative instruments in its consolidated balance sheets.

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 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. Standby letters of credit are written conditional commitments issued by the Company to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment were funded, the Company would seek payment from the customer under pre-arranged terms. The Company's policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements.

The contractual amounts of financial instruments with off‑balance sheet risk at September 30, 2015 and December 31, 2014, 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, 2015		December 31, 2014
Unused commitments to extend credit	$	1,268,504	$	520,659
Unused capacity on Warehouse Purchase Program loans	614,623		414,584
Standby letters of credit	18,808		7,391
Total unused commitments/capacity	$	1,901,935	$	942,634

In addition to the commitments above, the Company had overdraft protection available in the amounts of $87,605 and $73,044 at September 30, 2015 and December 31, 2014, respectively.

In regards 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.

The Company, at September 30, 2015, had FHLB letters of credit of $394,555 pledged to secure public deposits, repurchase agreements, and for other purposes required or permitted by law.

At September 30, 2015, the Company had $3,420 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.
