(1) Operations and Summary of Significant Accounting Policies

Organization and Nature of Business

Texas Capital Bancshares, Inc. (the "Company” or "TCBI"), a Delaware corporation, was incorporated in November 1996 and commenced banking operations in December 1998. The consolidated financial statements of the Company include the accounts of Texas Capital Bancshares, Inc. and its wholly owned subsidiary, Texas Capital Bank, National Association (the "Bank”). We serve the needs of commercial businesses and successful professionals and entrepreneurs located in Texas as well as operate several lines of business serving a regional or national clientele of commercial borrowers. We are primarily a secured lender, with the majority of our loans held for investment, excluding mortgage finance loans and other national lines of business, being made to businesses headquartered or with operations in Texas. Our national lines of business provide specialized lending products to businesses throughout the United States.

On December 9, 2019, the Company and Independent Bank Group, Inc. (“IBTX”) entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, on the terms and subject to the conditions therein, the Company would be merged with and into IBTX. On May 22, 2020, the Company and IBTX entered into an agreement (the “Mutual Termination Agreement”) pursuant to which the parties mutually agreed to terminate the Merger Agreement. Neither party paid a termination fee in connection with the termination of the Merger Agreement.

Basis of Presentation

Our accounting and reporting policies conform to accounting principles generally accepted in the United States ("GAAP") and to generally accepted practices within the banking industry. Certain prior period balances have been reclassified to conform to the current period presentation.

The consolidated interim financial statements are unaudited and certain information and footnote disclosures presented in accordance with GAAP have been condensed or omitted. In the opinion of management, the interim financial statements include all normal and recurring adjustments and the disclosures made are adequate to make the interim financial information not misleading. The consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our consolidated financial statements, and notes thereto, for the year ended December 31, 2019, included in our 2019 Form 10-K. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.

Revision of Prior Period Financial Statements

During the second quarter of 2020, the Company identified an error in our historical financial statements related to the accounting for certain share-based liabilities of a consolidated entity that contained put features, whereby the liabilities were not remeasured to their puttable value at each period end. The aggregate amount of the errors at each period end represented 1% or less of our stockholders' equity in all prior periods. In accordance with the guidance set forth in SEC Staff Bulletin 99, Materiality, and SEC Staff Accounting Bulletin 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financials, the Company concluded that the error was not material, individually or in the aggregate with other previously identified immaterial errors, to any prior periods, the current period or the trend in earnings from a quantitative and qualitative perspective. However, correcting the cumulative effect of the errors in the current period would have resulted in a material misstatement in the current period and, as such, we have revised our previously reported financial information contained in our Quarterly Report on Form 10-Q for the three and six-months ended June 30, 2019 to correct the immaterial error, as well as other previously identified immaterial errors. We will also revise previously reported financial information for these immaterial errors in our future filings, as applicable.

A summary of revisions to certain previously reported financial information is presented below:

(1)	March 31, 2020 reported balances of $1,668,329 and $2,803,533 for retained earnings and total equity, respectively were both adjusted down by $30,937 to revised balances of $1,637,392 and $2,772,596, respectively.

The share-based liabilities relate to agreements with certain employees of a subsidiary of the Company that was acquired in 2005. The terms of the agreements include a put feature, that when exercised, requires mandatory settlement by the Company of the share-based liability at a formulaic price. The put feature causes the liability to be remeasured to current puttable value at each period end. The impact of adjusting the liability to puttable value at each period is recorded in salaries and employee benefits expense. During the second quarter of 2020, put features were exercised on a portion of the outstanding liability. As of June 30, 2020, the carrying value of these share-based liabilities totaled $6.7 million and is recorded in other liabilities on the consolidated balance sheets.

Accounting Changes

On January 1, 2020, we adopted ASU 2016-13 "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"), which replaces the incurred loss methodology for determining our provision for credit losses and allowance for credit losses with an expected loss methodology that is referred to as the Current Expected Credit Loss ("CECL") model. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with ASU 2016-02 "Leases (Topic 842)". In addition, ASU 2016-13 made changes to the accounting for available-for-sale debt securities. One such change is to require credit-related impairments to be recognized in the allowance for credit losses rather than as a write-down of the securities' amortized cost basis when management does not intend to sell or believes that it is not more likely than not that they will be required to sell the securities prior to recovery of the securities amortized cost basis.

We adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost, off-balance sheet credit exposures and net investments in leases. Results for reporting periods beginning after January 1, 2020 are presented under ASU 2016-13 while prior period amounts continue to be reported in accordance with previously applicable GAAP.

We adopted ASU 2016-13 using the prospective transition approach for debt securities for which other-than-temporary impairment had been recognized prior to January 1, 2020. As a result, the amortized cost basis remains the same before and after the effective date of ASU 2016-13.

The following table illustrates the impact of adopting ASU 2016-13 and details how outstanding loan balances have been reclassified as a result of changes made to our primary portfolio segments under CECL:

In connection with our adoption of ASU 2016-13, changes were made to our primary portfolio segments to align with the methodology applied in determining the allowance under CECL. These changes included segregating energy loans into a stand-alone portfolio segment and reclassifying consumer and equipment leases into the commercial loan portfolio segment. Additionally, construction and real estate loans were combined into a single portfolio segment, referred to as real estate. The real estate loan portfolio segment includes loans further categorized as commercial real estate, residential homebuilder finance, secured by 1-4 family and an "other" category. See Allowance for Credit Losses - Loans below for further discussion of these portfolio segments.

Loans

Loans Held for Investment

Loans held for investment (including financing leases) are stated at the amount of unpaid principal reduced by deferred income (net of costs). Interest on loans is recognized using the simple interest method on the daily balances of the principal amounts outstanding. Loan origination fees, net of direct loan origination costs, and commitment fees are deferred and amortized as an adjustment to yield over the life of the loan, or over the commitment period, as applicable.

Restructured loans are loans on which, due to the borrower’s financial difficulties, we have granted a concession that we would not otherwise consider for borrowers of similar credit quality. This may include a transfer of real estate or other assets from the borrower, a modification of loan terms, or a combination of the two. Modifications of terms that could potentially qualify as a restructuring include reduction of contractual interest rate, extension of the maturity date at a contractual interest rate lower than the current rate for new debt with similar risk, a reduction of the face amount of debt or forgiveness of either principal or accrued interest. A loan continues to qualify as restructured until a consistent payment history or change in the borrower’s financial condition has been evidenced, generally for no less than twelve months. If the restructuring agreement specifies an interest rate at the time of the restructuring that is greater than or equal to the rate that we are willing to accept for a new extension of credit with comparable risk, then the loan is no longer considered a restructuring if it is in compliance with the modified terms in calendar years after the year of the restructure.

A loan is considered past due when a contractually due payment has not been received by the contractual due date. We place a loan on non-accrual when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed as a reduction of current period interest income. Interest income is subsequently recognized on a cash basis as long as the remaining book balance of the asset is deemed to be collectible. If collectability is questionable, then cash payments are applied to principal. A loan is placed back on accrual status when both principal and interest are current and it is probable that we will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement.

Table of Contents

Loans held for investment includes legal ownership interests in mortgage loans that we purchase through our mortgage warehouse lending division. The ownership interests are purchased from unaffiliated mortgage originators who are seeking additional funding through sale of the undivided ownership interests to facilitate their ability to originate loans. The mortgage originator has no obligation to offer and we have no obligation to purchase these interests. The originator closes mortgage loans consistent with underwriting standards established by approved investors, and, at the time of the sale to the investor, our ownership interest and that of the originator are delivered by us to the investor selected by the originator and approved by us. We typically purchase up to a 99% ownership interest in each mortgage with the originator owning the remaining percentage. These mortgage ownership interests are generally held by us for a period of less than 30 days and more typically 10-20 days. Because of conditions in agreements with originators designed to reduce transaction risks, under ASC 860, Transfers and Servicing of Financial Assets (“ASC 860”), the ownership interests do not qualify as participating interests. Under ASC 860, the ownership interests are deemed to be loans to the originators and payments we receive from investors are deemed to be payments made by or on behalf of the originator to repay the loan deemed made to the originator. Because we have an actual, legal ownership interest in the underlying residential mortgage loan, these interests are reported as extensions of credit to the originators that are secured by the mortgage loans as collateral.

Due to market conditions or events of default by the investor or the originator, we could be required to purchase the remaining interests in the mortgage loans and hold them beyond the expected 10-20 days. Mortgage loans acquired under these conditions would require mark-to-market adjustments to income and could require future allocations of the allowance for credit losses or be subject to charge-off in the event the loans become impaired.

Allowance for Credit Losses

The allowance for credit losses is an estimate of the expected credit losses in the loans held for investment and available-for-sale debt securities portfolios.

Loans

ASU 2016-13 replaces the incurred loss impairment model, which recognizes losses when it becomes probable that a credit loss will be incurred, with a requirement to recognize lifetime expected credit losses immediately when a financial asset is originated or purchased. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. Loans, or portions thereof, are charged off against the allowance when they are deemed uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off.

Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, credit quality, or term, as well as for changes in macroeconomic conditions, such as changes in unemployment rates, crude oil prices, property values or other relevant factors.

The allowance for credit losses is comprised of reserves measured on a collective (pool) basis based on a lifetime loss-rate model when similar risk characteristics exist. Reserves on loans that do not share risk characteristics are evaluated on an individual basis. In order to determine the allowance for credit losses, all loans are assigned a credit grade. Loans graded substandard or worse and greater than $500,000 are specifically reviewed for loss potential and when deemed appropriate are assigned a reserve based on an individual evaluation. For purposes of determining the pool-basis reserve, the remainder of the portfolio, representing all loans not assigned an individual reserve, is segregated first by portfolio segment, then by product type, to recognize differing risk profiles within portfolio segments, and finally by credit grade. Each credit grade within each product type is assigned a historical loss rate. These historical loss rates are then modified to incorporate our reasonable and supportable forecast of future losses at the portfolio segment level, as well as any necessary qualitative adjustments using a Portfolio Level Qualitative Factor ("PLQF") and/or a Portfolio Segment Level Qualitative Factor ("SLQF"). These modified historical loss rates are multiplied by the outstanding principal balance of each loan to calculate a required reserve. A similar process is employed to calculate a reserve assigned to off-balance sheet commitments, specifically unfunded loan commitments and letters of credit, and any needed reserve is recorded in other liabilities. The PLQF and SLQF are utilized to address factors that are not present in historical loss rates and are otherwise unaccounted for in the quantitative process. The PLQF is used to apply a qualitative adjustment across the entire portfolio of loans, while the SLQF is designed to apply a qualitative adjustment across a single portfolio segment. Even though portions of the allowance may be allocated to specific loans, the entire allowance is available for any credit that, in management’s judgment, should be charged off.

We generally use a two-year forecast period, based on a single consensus forecast scenario, using variables we believe are most relevant to each portfolio segment. For periods beyond which we are able to develop reasonable and supportable forecasts, we immediately revert to the average historical loss rate. The forecast period and scenario used is reviewed on a quarterly basis and

Table of Contents

may be adjusted based on management's view of the current economic conditions and level of predictability the forecast can provide.

Portfolio segments are used to pool loans with similar risk characteristics and align with our methodology for measuring expected credit losses. A summary of our primary portfolio segments is as follows:

Commercial. Our commercial loan portfolio is comprised of lines of credit for working capital, term loans and leases to finance equipment and other business assets across a variety of industries. These loans are used for general corporate purposes including financing working capital, internal growth, acquisitions and business insurance premiums and are generally secured by accounts receivable, inventory, equipment and other assets of our clients’ businesses. Our commercial loan portfolio also includes consumer loans because our small portfolio of consumer loans is largely comprised of accommodation loans to individuals associated with our commercial clients.

Energy. Our energy loan portfolio is primarily comprised of loans to exploration and production (“E&P”) companies that are generally collateralized with proven reserves based on appropriate valuation standards that take into account the risk of oil and gas price volatility. The majority of this portfolio is first lien, senior secured, reserve-based lending, which we believe is the lowest-risk form of energy lending. Energy loans are impacted by commodity price volatility, as well as changes in consumer and business demand.

Mortgage finance. Mortgage finance loans relate to our mortgage warehouse lending operations in which we purchase mortgage loan ownership interests from unaffiliated mortgage originators that are generally held by us for a period of less than 30 days and more typically 10-20 days before they are sold to an approved investor. Volumes fluctuate based on the level of market demand for the product and the number of days between purchase and sale of the loans, which can be affected by changes in overall market interest rates and housing demand and tend to peak at the end of each month. Mortgage finance loans are consistently underwritten based on standards established by the approved investors. Market conditions or events of default by an investor or originator could require that we repurchase the remaining interests in the mortgage loans and hold them beyond the expected 10-20 days.

Real estate. Our real estate portfolio is comprised of the following types of loans:

Commercial real estate ("CRE"). Our CRE portfolio is comprised of both construction/development financing and limited term financing provided to professional real estate developers and owners/managers of commercial real estate projects and properties who have a demonstrated record of past success with similar properties. Collateral properties include office buildings, warehouse/distribution buildings, shopping centers, hotels/motels, senior living, apartment buildings and residential and commercial tract development. The primary source of repayment on these loans is expected to come from the sale, permanent financing or lease of the real property collateral. CRE loans are impacted by fluctuations in collateral values, as well as the ability of the borrower to obtain permanent financing.

Residential homebuilder finance ("RBF"). The RBF portfolio is comprised of loans made to residential builders and developers. Loans to residential builders are typically in the form of uncommitted guidance lines and are for the purpose of developing lots into single-family homes, while loans to developers are typically in the form of borrowing base lines extended for the purpose of acquiring and developing raw land into lots that can be further sold to home builders. RBF loans, if not structured and monitored correctly, can be impacted by volatility in consumer demand, as well as fluctuation in housing prices.

Secured by 1-4 family. This category of loans includes both first and second lien loans made for the purpose of purchasing or constructing 1-4 family residential dwellings, as well as home equity revolving lines of credit and loans to purchase lots for future construction of 1-4 family residential dwellings.

Other. The "other" category is primarily comprised of real estate loans originated through a Small Business Administration (SBA) program where repayment is partially guaranteed by the SBA, as well as other loans secured by real estate where the primary source of repayment is not expected to come from the sale or lease of the real property collateral.

We have several pass credit grades that are assigned to loans based on varying levels of risk, ranging from credits that are secured by cash or marketable securities, to watch credits which have all the characteristics of an acceptable credit risk but warrant more than the normal level of monitoring. Within our criticized/classified credit grades are special mention, substandard and doubtful. Special mention loans are those that are currently protected by the sound worth and paying capacity of the borrower, but that are potentially weak and constitute an additional credit risk. These loans have the potential to deteriorate to a substandard grade due to the existence of financial or administrative deficiencies. Substandard loans have a well-defined weakness or weaknesses that jeopardizes the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Some substandard loans are inadequately protected by the sound worth and paying capacity of the borrower and of the collateral pledged and may be considered impaired. Substandard loans can be accruing or can be on non-accrual depending on the circumstances of the individual loans.

Table of Contents

Loans classified as doubtful have all the weaknesses inherent in substandard loans with the added characteristics that the weaknesses make collection in full highly questionable and improbable. The possibility of loss is extremely high. All doubtful loans are on non-accrual.

The methodology used in the estimation of the allowance, which is performed at least quarterly, is designed to be dynamic and responsive to changes in portfolio credit quality and forecasted economic conditions. Changes are reflected in the pool-basis allowance and in reserves assigned on an individual basis as the collectability of classified loans is evaluated with new information. As our portfolio has matured, historical loss ratios have been closely monitored. The review of the appropriateness of the allowance is performed by executive management and presented to the audit and risk committees of our board of directors for their review. The committees report to the board as part of the board's review on a quarterly basis of our consolidated financial statements.

When management determines that foreclosure is probable, and for certain collateral-dependent loans where foreclosure is not considered probable, expected credit losses are based on the fair value of the collateral adjusted for selling costs, when appropriate. A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral.

Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless either of the following applies: management has a reasonable expectation that a loan will be restructured, or the extension or renewal options are included in the borrower contract and are not unconditionally cancellable by us.

We do not measure an allowance for credit losses on accrued interest receivable balances because these balances are written off in a timely manner as a reduction to interest income when loans are placed on non-accrual status as discussed above.

Investment Securities

Available-for-Sale

For available-for-sale debt securities in an unrealized loss position, we first assess whether we intend to sell or it is more-likely-than-not that we will be required to sell the securities before recovery of the amortized cost basis. If either of these criteria is met, the securities' amortized cost basis is written down to fair value as a current period expense. If either of the above criteria is not met, we evaluate whether the decline in fair value is the result of credit losses or other factors. In making this assessment, we may consider various factors including the extent to which fair value is less than amortized cost, performance of any underlying collateral and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected are compared to the amortized cost basis of the security and any excess of the amortized cost basis over the present value of expected cash flows is recorded as an allowance for credit loss, limited to the amount by which the fair value is less than the amortized cost basis. Any impairment not recorded through an allowance for credit loss is recognized in other comprehensive income as a non credit-related impairment.

We have made a policy election to exclude accrued interest from the amortized cost basis of available-for-sale debt securities and report accrued interest separately in accrued interest and other assets in the consolidated balance sheets. Available-for-sale debt securities are placed on non-accrual status when we no longer expect to receive all contractual amounts due, which is generally at 90 days past due. Accrued interest receivable is reversed against interest income when a security is placed on non-accrual status. Accordingly, we do not recognize an allowance for credit loss against accrued interest receivable.

All debt securities are available-for-sale as of June 30, 2020 and December 31, 2019.

Included in debt securities available-for-sale are Credit Risk Transfer ("CRT") securities. CRT securities represent unsecured obligations issued by government sponsored entities ("GSEs") such as Freddie Mac and are designed to transfer mortgage credit risk from the GSE to private investors. CRT securities are structured to be subject to the performance of a reference pool of mortgage loans in which we share in 50% of the first losses with the GSE. If the reference pool incurs losses, the amount we will recover on the notes is reduced by our share of the amount of such losses, which could potentially be up to 100% of the amount outstanding. Unrealized losses recognized in accumulated other comprehensive income ("AOCI") for the CRT securities are primarily related to the difference between the current market rate for similar securities and the stated interest rate and are not considered to be related to credit loss events. The CRT securities are generally interest-only for an initial period of time and are restricted from being transferred until a future date.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for credit losses, the fair value of financial instruments and the status of contingencies are particularly susceptible to significant change.

We conduct periodic reviews of securities with unrealized losses to evaluate whether the decline in fair value has resulted from credit losses or other factors. Based on the results of our periodic review, at June 30, 2020 management believes that unrealized losses on the tax-exempt asset-backed securities and CRT securities have resulted from factors not deemed credit-related and no allowance for credit loss was recorded. We have evaluated the near-term prospects of each securities portfolio in relation to the severity of the non credit-related unrealized losses and adverse conditions related to the securities among other factors. Based on that evaluation management has determined that we have the ability and intent to hold the securities until recovery of fair value and have recorded the non credit-related unrealized losses in AOCI.

Available-for-sale debt securities with carrying values of approximately $3.0 million and $1.4 million were pledged to secure certain customer repurchase agreements and deposits, respectively, at June 30, 2020. The comparative amounts at December 31, 2019 were $3.5 million and $1.2 million, respectively.

Equity Securities

During the first quarter of 2020, we adopted ASU 2016-13, which replaces the incurred loss methodology for determining our provision for credit losses and allowance for credit losses with an expected loss methodology that is referred to as the CECL model. Upon adoption, the allowance for credit losses was increased by $9.1 million, which included a $563,000 increase to the allowance for off-balance sheet credit losses, with no impact to the consolidated statement of income. We recorded a $100.0 million provision for credit losses for the second quarter of 2020, compared to $96.0 million for the first quarter of 2020 and $27.0 million for the second quarter of 2019. The increased provision for credit losses resulted primarily from an increase in charge-offs and reserve build related to higher criticized loan levels and continued economic uncertainty from the COVID-19 pandemic. We recorded $74.1 million in net charge-offs during the second quarter of 2020, including $62.4 million in energy charge-offs and $8.1 million in leveraged lending charge-offs, all of which were loans that had been previously identified as problem loans, compared to $57.7 million during the first quarter of 2020 and $20.0 million during the second quarter of 2019. Criticized loans totaled $1.0 billion at June 30, 2020, compared to $584.1 million at December 31, 2019 and $629.1 million at June 30, 2019. The increase in criticized loans was predominantly in special mention and was primarily due to the continued downgrade of loans that have been impacted by the COVID-19 pandemic or that are in categories that are expected to be more significantly impacted by COVID-19.

A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral.

(1)	Loans past due 90 days and still accruing includes premium finance loans of $14.8 million. These loans are generally secured by obligations of insurance carriers to refund premiums on canceled insurance policies. The receipt of the refund of premiums from the insurance carriers can take 180 days or longer from the cancellation date.


(2)	As of June 30, 2020 and December 31, 2019, none of our non-accrual loans were earning interest income on a cash basis. Additionally, no interest income was recognized on non-accrual loans for the six months ended June 30, 2020. Accrued interest of $708,000 was reversed during the six months ended June 30, 2020.

On January 1, 2020, the date we adopted CECL, non-accrual loans totaled $225.4 million, and included $88.6 million in commercial loans, $125.0 million in energy loans, $9.4 million in CRE loans, $881,000 in real estate-other loans and

$1.4 million in secured by 1-4 family loans.

As of June 30, 2020 and December 31, 2019, we did not have any loans considered restructured that were not on non-accrual. Of the non-accrual loans at June 30, 2020 and December 31, 2019, $23.7 million and $35.1 million, respectively, met the criteria for restructured. These loans had no unfunded commitments at their respective balance sheet dates.

The following table details the recorded investment at June 30, 2020 and June 30, 2019 of loans restructured during the six months ended June 30, 2020 and June 30, 2019 by type of modification:

Restructured loans generally include terms to temporarily place the loan on interest only, extend the payment terms or reduce the interest rate. We did not forgive any principal on the above restructured loans. At June 30, 2020 and 2019, all of the above restructured loans were on non-accrual. The restructuring of the loans did not have a significant impact on our allowance for credit losses at June 30, 2020 or 2019. As of June 30, 2020 and 2019, we did not have any loans that were restructured within the last 12 months that subsequently defaulted.

In response to the COVID-19 pandemic, we implemented a short-term modification program in late March 2020 to provide temporary payment relief to borrowers who meet the program's qualifications. This program allows for a deferral of payments for 90 days, which we may extend for an additional 90 days, for a maximum of 180 days on a cumulative basis. The deferred payments along with interest accrued during the deferral period are due and payable on the maturity date of the existing loan. As of June 30, 2020, we have granted temporary modifications on 482 loans with a total outstanding balance of $1.2 billion, resulting in the deferral of $10.8 million in interest payments. Under the applicable guidance, none of these loans were considered restructured as of June 30, 2020.

(1)	Includes $5.8 million of loans held for sale that are carried at lower of cost or market as of December 31, 2019 and $299,000 as of December 31, 2018, as well as $1.1 million as of June 30, 2019. There were no loans held for sale carried at lower of cost or market as of June 30, 2020.

No loans held for sale were on non-accrual as of June 30, 2020 or December 31, 2019. At June 30, 2020 and December 31, 2019, we had $10.2 million and $8.2 million, respectively, of loans held for sale that were 90 days or more past due. The $10.2 million in loans held for sale that were 90 days or more past due at June 30, 2020 included $4.6 million of loans guaranteed by U.S. government agencies that were purchased out of Ginnie Mae securities and recorded as loans held for sale, at fair value, on the balance sheet. Interest on these past due loans accrues at the debenture rate guaranteed by the U.S. government. Also included in the $10.2 million were $5.2 million in loans that, pursuant to Ginnie Mae servicing guidelines, we have the unilateral right, but not the obligation, to repurchase if defined delinquent loan criteria are met, and therefore must record as held for sale on our balance sheet regardless of whether the repurchase option has been exercised. At December 31, 2019, $6.0 million of the $8.2 million in loans held for sale were loans guaranteed by U.S. government agencies that were purchased out of Ginnie Mae securities and recorded as loans held for sale, at fair value, on the balance sheet and $1.9 million were loans that we have the unilateral right, but not the obligation, to repurchase if defined delinquent loan criteria are met.

From time to time we retain the right to service the loans sold through our Mortgage Correspondent Aggregation ("MCA") program, creating mortgage servicing rights ("MSRs") which are recorded as assets on our balance sheet. A summary of MSR activity is as follows:



	Six months ended June 30,
(in thousands)	2020			2019
MSRs:
Balance, beginning of year	$	70,707		$	42,474

MSRs, net	$	75,451		$	47,785
MSRs, fair value	$	75,451		$	47,845

At June 30, 2020 and December 31, 2019, our servicing portfolio of residential mortgage loans had outstanding principal balances of $10.2 billion and $6.7 billion, respectively.

In connection with the servicing of these loans, we hold deposits in the name of investors representing escrow funds for taxes and insurance, as well as collections in transit to the investors. These escrow funds are segregated and held in separate non-interest-bearing deposit accounts at the Bank. These deposits, included in total non-interest-bearing deposits on the consolidated balance sheets, were $128.0 million at June 30, 2020 and $63.7 million at December 31, 2019.

Table of Contents

The estimated fair value of the MSR assets is obtained from an independent third party and reviewed by management on a quarterly basis. MSRs typically do not trade in an active, open market with readily observable prices; as such, the fair value of MSRs is determined using a discounted cash flow model to calculate the present value of the estimated future net servicing income. The assumptions utilized in the discounted cash flow model are based on market data for comparable assets, where available. Each quarter, management and the independent third party review the key assumptions used in the discounted cash flow model and make adjustments as necessary to estimate the fair value of the MSRs. At June 30, 2020, the estimated fair value of MSRs was adjusted as a result of the decline in mortgage interest rates experienced in the first six months of 2020, which resulted in a $20.8 million impairment charge, compared to a $5.8 million impairment charge for the first six months of 2019. To mitigate exposure to potential impairment charges from adverse changes in the fair value of our residential MSR portfolio, we enter into certain derivative contracts, as is further discussed in Note 10 - Derivative Financial Instruments. The following summarizes the assumptions used by management to determine the fair value of MSRs:



	June 30, 2020		December 31, 2019
Average discount rates	9.18	%	9.06	%
Expected prepayment speeds	17.15	%	13.11	%
Weighted-average life, in years	4.7		5.8

A sensitivity analysis of changes in the fair value of our MSR portfolio resulting from certain key assumptions is presented in the following table:

These sensitivities are hypothetical and actual results may differ materially due to a number of factors. The effect on fair value of a 10% variation in assumptions generally cannot be determined with confidence because the relationship of the change in assumptions to the fair value may not be linear. Additionally, the impact of a variation in a particular assumption on the fair value is calculated while holding other assumptions constant. In reality, changes in one factor may be correlated with changes in other factors, which could impact the sensitivity analysis as presented.

In conjunction with the sale and securitization of loans held for sale, we may be exposed to liability resulting from repurchase, indemnification and make-whole agreements. Our estimated exposure related to those agreements totaled $2.5 million and $3.6 million at June 30, 2020 and December 31, 2019, respectively, and is recorded in other liabilities on the consolidated balance sheets. We incurred $4.5 million in losses due to make-whole obligations during the six months ended June 30, 2020 compared to $1.0 million during the six months ended June 30, 2019. The increase in make-whole obligation losses is primarily related to an increase in early payoffs resulting from the declining interest rate environment.

(6) Financial Instruments with Off-Balance Sheet Risk

The table below presents our financial instruments with off-balance sheet risk, as well as the activity in the allowance for off-balance sheet credit losses related to those financial instruments. This allowance is recorded in other liabilities on the consolidated balance sheets.

(7) Regulatory Restrictions

The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory (and possibly additional discretionary) actions by regulators that, if undertaken, could have a direct material adverse effect on the Company’s and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s and the Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

The Basel III regulatory capital framework (the "Basel III Capital Rules") adopted by U.S. federal regulatory authorities, among other things, (i) establishes the capital measure called "Common Equity Tier 1" ("CET1"), (ii) specifies that Tier 1 capital consist of CET1 and "Additional Tier 1 Capital" instruments meeting stated requirements, (iii) requires that most deductions/adjustments to regulatory capital measures be made to CET1 and not to other components of capital and (iv) defines the scope of the deductions/adjustments to the capital measures.

Additionally, the Basel III Capital Rules require that we maintain a 2.5% capital conservation buffer with respect to each of CET1, Tier 1 and total capital to risk-weighted assets, which provides for capital levels that exceed the minimum risk-based capital adequacy requirements. A financial institution with a conservation buffer of less than the required amount is subject to limitations on capital distributions, including dividend payments and stock repurchases, and certain discretionary bonus payments to executive officers.

In the first quarter of 2020, U.S. federal regulatory authorities issued an interim final rule that provides banking organizations that adopt CECL during the 2020 calendar year with the option to delay for two years the estimated impact of CECL on regulatory capital relative to regulatory capital determined under the prior incurred loss methodology, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided during the initial two-year delay (i.e., a five-year transition in total). In connection with our adoption of CECL on January 1, 2020, we have elected to utilize the five-year CECL transition.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of CET1, Tier 1 and total capital to risk-weighted assets, and of Tier 1 capital to average assets, each as defined in the regulations. Management believes, as of June 30, 2020, that the Company and the Bank meet all capital adequacy requirements to which they are subject.

Financial institutions are categorized as well capitalized or adequately capitalized based on minimum total risk-based, Tier 1 risk-based, CET1 and Tier 1 leverage ratios. As shown in the table below, the Company’s capital ratios exceeded the regulatory definition of adequately capitalized as of June 30, 2020 and December 31, 2019. Based upon the information in its most recently filed call report, the Bank met the capital ratios necessary to be well capitalized. The regulatory authorities can apply changes in classification of assets and such changes may retroactively subject the Company to changes in capital ratios. Any such change could reduce one or more capital ratios below well-capitalized status. In addition, a change may result in imposition of additional assessments by the FDIC or could result in regulatory actions that could have a material adverse effect on our financial condition and results of operations.

Because our Bank had less than $15.0 billion in total consolidated assets as of December 31, 2009, we are allowed to continue to classify our trust preferred securities, all of which were issued prior to May 19, 2010, as Tier 1 capital.

Table of Contents

The table below summarizes our actual and required capital ratios under the Basel III Capital Rules. The ratios presented below include the effects of our election to utilize the five-year CECL transition described above.

(1)	The Tier 1 capital ratio (to average assets) is not impacted by the Basel III Capital Rules; however, the Federal Reserve Board and the FDIC may require the Company and the Bank, respectively, to maintain a Tier 1 capital ratio (to average assets) above the required minimum.

Our mortgage finance loan volumes can increase significantly at month-end, causing a meaningful difference between ending balance and average balance for any period. At June 30, 2020, our mortgage finance loans were $9.0 billion compared to the average for the quarter ended June 30, 2020 of $8.7 billion. As CET1, Tier 1 and total capital ratios are calculated using quarter-end risk-weighted assets and our mortgage finance loans are 100% risk-weighted (excluding MCA mortgage loans held for sale, which receive lower risk weights), the period-end fluctuation in these balances can significantly impact our reported ratios. Due to the actual risk profile and liquidity of this asset class, we manage capital allocated to mortgage finance loans based on changing trends in average balances and do not believe that the period-end balance is representative of risk characteristics that would justify higher allocations. However, we monitor our capital allocation to confirm that all capital levels remain above well-capitalized levels.

Dividends that may be paid by banks are routinely restricted by various regulatory authorities. The amount that can be paid in any calendar year without prior approval of our Bank’s regulatory agencies cannot exceed the lesser of the net profits (as defined) for that year plus the net profits for the preceding two calendar years, or retained earnings. The Basel III Capital Rules further limit the amount of dividends that may be paid by our Bank. No dividends were declared or paid on our common stock during the six months ended June 30, 2020, or 2019.

(8) Stock-based Compensation

We have long-term incentive plans under which stock-based compensation awards are granted to employees and directors by the board of directors, or its designated committee. Grants are subject to vesting requirements and may include, among other things, nonqualified stock options, stock appreciation rights ("SARs"), restricted stock units ("RSUs"), restricted stock and performance units, or any combination thereof. There are 2,550,000 total shares authorized for grant under the plans.

(9) Fair Value Disclosures

We determine the fair market values of our assets and liabilities measured at fair value on a recurring and nonrecurring basis using the fair value hierarchy as prescribed in ASC 820. The standard describes three levels of inputs that may be used to measure fair value as provided below.


Level 1	Quoted prices in active markets for identical assets or liabilities.


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

Level 3

Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair values requires significant management judgment or estimation.

Tax-exempt asset-backed securities

The fair value of tax-exempt asset-backed securities is based on a discounted cash flow model, which utilizes Level 3, or unobservable, inputs, the most significant of which were a discount rate and weighted-average life. At June 30, 2020, the discount rates utilized ranged from 3.52% to 3.55% and the weighted-average life ranged from 6.5 years to 7.7 years. On a combined amortized cost weighted-average basis a discount rate of 3.54% and weighted-average life of 7.1 years were utilized to determine the fair value of these securities at June 30, 2020. At December 31, 2019, the combined weighted-average discount rate and weighted-average life utilized were 2.99% and 7.0 years, respectively.

CRT securities

The fair value of CRT securities is based on a discounted cash flow model, which utilizes Level 3, or unobservable, inputs, the most significant of which were a discount rate and weighted-average life. At June 30, 2020, the discount rates utilized ranged from 2.99% to 7.20% and the weighted-average life ranged from 7.0 years to 11.1 years. On a combined amortized cost weighted-average basis a discount rate of 4.39% and a weighted-average life of 8.4 years were utilized to determine the fair value of these securities at June 30, 2020. At December 31, 2019, the combined weighted-average discount rate and combined weighted-average life utilized were 4.54% and 9.3 years, respectively.

Loans held for sale

The fair value of loans held for sale using Level 3 inputs include loans that cannot be sold through normal sale channels and thus require significant management judgment or estimation when determining the fair value. The fair value of such loans is generally based upon quoted prices of comparable loans with a liquidity discount applied. At June 30, 2020, the fair value of these loans was calculated using a weighted-average discounted price of 95.4%, compared to 94.1% at December 31, 2019.

Table of Contents

Loans held for investment

Certain collateral-dependent loans held for investment are reported at fair value when, based upon an individual evaluation, the specific allocation of the allowance for credit losses that is deducted from the loan's amortized cost is based upon the fair value of the loan's underlying collateral. The $72.6 million fair value of loans held for investment at June 30, 2020 reported above includes loans held for investment with a carrying value of $96.3 million that were reduced by specific allowance allocations totaling $23.7 million based on collateral valuations utilizing Level 3 inputs. The $109.6 million fair value of loans held for investment at December 31, 2019 reported above includes loans with a carrying value of $145.4 million that were reduced by specific allowance allocations totaling $35.8 million based on collateral valuations utilizing Level 3 inputs.

Fair Value of Financial Instruments

GAAP requires disclosure of fair value information about financial instruments, whether or not recognized on the balance sheet, for which it is practical to estimate that value. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. This disclosure does not and is not intended to represent the fair value of the Company.

The estimated fair value for cash and cash equivalents, variable rate loans and variable rate debt approximates carrying value. The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments:

Investment Securities

Within the investment securities portfolio, we hold equity securities related to our non-qualified deferred compensation plan that are valued using quoted market prices for identical equity securities in an active market, and are classified as Level 1 assets in the fair value hierarchy. The fair value of the remaining equity securities and residential mortgage-backed securities in our investment portfolio are based on prices obtained from independent pricing services that are based on quoted market prices for the same or similar securities, and are characterized as Level 2 assets in the fair value hierarchy. We have obtained documentation from our primary pricing service regarding their processes and controls applicable to pricing investment securities, and on a quarterly basis we independently verify the prices that we receive from the service provider using two additional independent pricing sources. We also hold tax-exempt asset-backed securities and CRT securities that are valued

Table of Contents

using a discounted cash flow model, which utilizes Level 3 inputs, and are classified as Level 3 assets in the fair value hierarchy.

Loans Held for Sale

Fair value for loans held for sale is derived from quoted market prices for similar loans, in which case they are characterized as Level 2 assets in the fair value hierarchy, or is derived from third party pricing models, in which case they are characterized as Level 3 assets in the fair value hierarchy.

Derivatives

The estimated fair value of interest rate swaps and caps is obtained from independent pricing services based on quoted market prices for similar derivative contracts and these financial instruments are characterized as Level 2 assets and liabilities in the fair value hierarchy. On a quarterly basis, we independently verify the fair value using an additional independent pricing source. Foreign currency forward contracts are valued based upon quoted market prices obtained from independent pricing services for similar derivative contracts. As such, these financial instruments are characterized as Level 2 assets and liabilities in the fair value hierarchy. The derivative instruments related to the loans held for sale portfolio include loan purchase commitments and forward sale commitments. Loan purchase commitments are valued based upon the fair value of the underlying mortgage loans to be purchased, which is based on observable market data for similar loans. Forward sale commitments are valued based upon quoted market prices from brokers. As such, these loan purchase commitments and forward sales commitments are characterized as Level 2 assets or liabilities in the fair value hierarchy. The derivative instruments related to our residential MSRs include interest rate swap futures and forward sale commitments. The interest rate swap futures are valued based on quoted market prices obtained from brokers for similar derivative contracts, while the forward sale commitments are valued based on the fair value of the underlying mortgage loans to be purchased, which is based on observable market data for similar loans. As such, these derivative instruments are characterized as Level 2 assets and liabilities in the fair value hierarchy.

During the second quarter of 2020, we initiated a strategy to mitigate exposure to potential impairment losses from adverse changes in the fair value of our residential MSR portfolio using interest rate derivative contracts, primarily interest rate swap futures and forward sale commitments of mortgage-backed securities. These derivative instruments are considered highly liquid and can be settled daily, which allows us to dynamically manage our exposure. The derivative instruments are used to

Table of Contents

economically hedge the fair value of the residential MSR portfolio impacted by changes in anticipated prepayments resulting from mortgage interest rate movements and are classified as other assets and other liabilities on the consolidated balance sheets. Any unrealized or realized gains/(losses) related to derivatives economically hedging the residential MSR portfolio are recognized in servicing-related expenses along with changes to the MSR valuation allowance.

The weighted-average received and paid interest rates for interest rate swaps outstanding were as follows:



	June 30, 2020 Weighted-Average Interest Rate				December 31, 2019 Weighted-Average Interest Rate
	Received		Paid		Received		Paid
Non-hedging interest rate swaps	3.23	%	1.44	%	3.94	%	3.26	%

The weighted-average strike rate for outstanding interest rate caps was 3.38% at June 30, 2020 and 3.29% at December 31, 2019.

Our credit exposure on derivative instruments is limited to the net favorable value and interest payments by each counterparty. In some cases collateral may be required from the counterparties involved if the net value of the derivative instruments exceeds a nominal amount. Our credit exposure associated with these instruments, net of any collateral pledged, was approximately $143.1 million at June 30, 2020 and approximately $48.7 million at December 31, 2019. Collateral levels are monitored and adjusted on a regular basis for changes in interest rate swap and cap values, as well as for changes in the value of forward sale commitments. At June 30, 2020, we had $134.5 million in cash collateral pledged for these derivatives, of which $128.9 million was included in interest-bearing deposits in other banks and $5.6 million was included in accrued interest receivable and other assets. At December 31, 2019, we had $56.6 million in cash collateral pledged for these derivatives, of which $54.3 million was included in interest-bearing deposits in other banks and $2.3 million was included in accrued interest receivable and other assets.

We also enter into credit risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which we are either a participant or a lead bank. The risk participation agreements entered into by us as a participant bank provide credit protection to the financial institution counterparty should the borrower fail to perform on its interest rate derivative contract with that financial institution. We are party to 8 risk participation agreements where we are a participant bank with a notional amount of $110.7 million at June 30, 2020, compared to 12 risk participation agreements having a notional amount of $146.7 million at December 31, 2019. The maximum estimated exposure to these agreements, assuming 100% default by all obligors, was approximately $7.0 million at June 30, 2020 and $3.6 million at December 31, 2019. The fair value of these exposures was insignificant to the consolidated financial statements at both June 30, 2020 and December 31, 2019. Risk participation agreements entered into by us as the lead bank provide credit protection to us should the borrower fail to perform on its interest rate derivative contract with us. We are party to 16 risk participation agreements where we are the lead bank having a notional amount of $166.9 million at June 30, 2020, compared to 12 agreements having a notional amount of $145.9 million at December 31, 2019.

(11) New Accounting Standards

ASU 2019-12 "Income Taxes (Topic 740)" ("ASU 2019-12") simplifies the accounting for income taxes by removing certain exceptions and improves the consistent application of GAAP by clarifying and amending other existing guidance. ASU 2019-012 will be effective for us on January 1, 2021 and is not expected to have any material impact on our consolidated financial statements.

ASU 2020-01 "Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)" ("ASU 2020-01") clarifies the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. ASU 2020-01 will be effective for us on January 1, 2021 and is not expected to have any material impact on our consolidated financial statements.

ASU 2020-02 "Financial Instruments - Credit Losses (Topic 326) and Leases (Topic 842)" ("ASU 2020-02") incorporates SEC SAB 119 (updated from SAB 102) into the Accounting Standards Codification (the "Codification") by aligning SEC recommended policies and procedures with ASC 326. ASU 2020-02 was effective on January 1, 2020 and has not had a significant impact on our documentation requirements.

ASU 2020-03 "Codification Improvements to Financial Instruments" ("ASU 2020-03") revised a wide variety of topics in the Codification with the intent to make the Codification easier to understand and apply by eliminating inconsistencies and

Table of Contents

providing clarifications. ASU 2020-03 was effective immediately upon its release in March 2020 and did not have a material impact on our consolidated financial statements.

ASU 2020-04, "Reference Rate Reform (Topic 848)" ("ASU 2020-04") provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest rate benchmarks. For transactions that are modified because of reference rate reform and that meet certain scope guidance (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification will be considered "minor" so that any existing unamortized origination fees/costs would carry forward and continue to be amortized and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. ASU 2020-04 also provides numerous optional expedients for derivative accounting. ASU 2020-04 is effective March 12, 2020 through December 31, 2022. An entity may elect to apply ASU 2020-04 for contract modifications as of January 1, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a Topic or an Industry Subtopic within the Codification, the amendments in this ASU must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. We anticipate this ASU will simplify any modifications we execute between the selected start date (yet to be determined) and December 31, 2022 that are directly related to LIBOR transition by allowing prospective recognition of the continuation of the contract, rather than extinguishment of the old contract resulting in writing off unamortized fees/costs. We are evaluating the impacts of this ASU and have not yet determined whether LIBOR transition and this ASU will have material effects on our business operations and consolidated financial statements.

including the effects from declines in the level of drilling and production related to volatility in oil and gas prices and the effects of the COVID-19 pandemic.


•	Adverse changes in economic or market conditions, in Texas, the United States or internationally, that could affect the credit quality of our loan portfolio or our operating performance.


•	Unanticipated effects from the Tax Cuts and Jobs Act of 2017 may limit its benefits or adversely impact our business, which could include decreased demand for borrowing by our middle market customers or increased price competition that offsets the benefits of decreased federal income tax expense.


•	Unexpected market conditions or regulatory changes that could cause access to capital market transactions and other sources of funding to become more difficult to obtain on terms and conditions that are acceptable to us.


•	The inadequacy of our available funds to meet our deposit, debt and other obligations as they become due, or our failure to maintain our capital ratios as a result of adverse changes in our operating performance or financial condition, or changes in applicable regulations or regulator interpretation of regulations impacting our business or the characterization or risk weight of our assets.


•	The failure to effectively balance our funding sources with cash demands by depositors and borrowers.


•	The failure to manage information systems risk or to prevent cyber-attacks against us, our customers or our third party vendors, or to manage risks from disruptions or security breaches affecting us, our customers or our third party vendors, which risk risks have been materially enhanced by our increased reliance on technology to support associates working outside our offices.


•	The failure to effectively manage our interest rate risk resulting from unexpectedly large or sudden changes in interest rates, maturity imbalances in our assets and liabilities, potential adverse effects to our borrowers including their inability to repay loans with increased interest rates and the impact to our net interest income from the increasing cost of interest-bearing deposits.


•	The failure of our enterprise risk management framework, our compliance program, or our corporate governance and supervisory oversight functions to timely identify and address emerging risks adequately, which may result in unexpected losses.


•	Uncertainty regarding the future of the London Interbank Offered Rate ("LIBOR"), and the potential transition away from LIBOR toward new interest rate benchmarks.


•	Legislative and regulatory changes imposing further restrictions and costs on our business, a failure to remain well capitalized or well managed status or regulatory enforcement actions against us, and uncertainty related to future implementation and enforcement of regulatory requirements resulting from the current political environment.


•	Changes in the monetary and fiscal policies of the U.S. Government, including policies of the U.S. Department of Treasury and the Federal Reserve.


•	The failure to successfully execute our business strategy, which may include expanding into new markets, developing and launching new lines of business or new products and services within the expected timeframes and budgets or to successfully manage the risks related to the development and implementation of these new businesses, products or services.


•	The failure to attract and retain key personnel or the loss of key individuals or groups of employees, including our ability to identify, employ and retain a successor chief executive officer.


•	Increased or more effective competition from banks and other financial service providers in our markets.

Overview of Our Business Operations

We commenced our banking operations in December 1998. An important aspect of our growth strategy has been our ability to effectively service and manage a large number of loans and deposit accounts in multiple markets in Texas, as well as several lines of business serving a regional or national clientele of commercial borrowers. Accordingly, we have created an operations infrastructure sufficient to support our lending and banking operations that we continue to build out as needed to serve a larger customer base and specialized industries.

On December 9, 2019, we and Independent Bank Group, Inc. ("IBTX") entered into a merger agreement to combine the companies in an all-stock merger of equals. On May 22, 2020, we and IBTX mutually agreed to terminate the merger agreement. The termination was approved by each company's board of directors after careful consideration of the significant impact of the COVID-19 pandemic on global markets and on the companies’ ability to fully realize the benefits expected to be achieved through the merger. Neither party paid a termination fee in connection with the termination of the merger agreement.

In response to the pressures of the current economic environment and a refinement of our strategy, we took actions during the second quarter of 2020 which are expected to decrease our non-interest expenses, including a workforce reduction and write-offs of certain software assets. Significant transactions affecting our income statement during the second quarter of 2020 included:


•	$100.0 million provision for credit losses; driven by an increase in charge-offs and reserve build related to higher criticized loan levels and continued economic uncertainty from the COVID-19 pandemic,


•	$26.6 million in non-recurring software expenses; including $20.7 million in write-offs of certain software assets and $5.9 million in technology expense related to the roll-out of our Paycheck Protection Program ("PPP") capabilities,


•	$18.0 million in severance accruals related to the workforce reduction referenced above,


•	$10.5 million in final merger-related expenses, and


•	$9.1 million MSR impairment.

While these expenses had a significant impact on our second quarter operating results, we believe that we are better positioned to improve our core profitability going forward as the non-interest expense items are not expected to recur in future periods.

We continue to focus on balance sheet strength and while we intend to operate with above-average liquidity in response to this uncertain economic environment, we believe opportunities exist to improve core earnings by reducing or replacing higher cost funding sources and improving the earning asset mix. In the first few weeks of July 2020, we began to utilize low-yielding liquidity assets to increase the balance of our securities portfolio in an effort to improve yields in future periods.

Our organic growth model and the depth of talent on our team have built a resilient business with lasting client relationships and a record of value creation through dynamic markets and business cycles.

Impact of COVID-19

Overview

In March 2020, the outbreak of COVID-19 was recognized as a pandemic by the World Health Organization. The spread of COVID-19 has created a global public health crisis that has resulted in unprecedented uncertainty, volatility and disruption in financial markets and in governmental, commercial and consumer activity in the United States and globally, including the markets that we serve. Governmental responses to the pandemic have included orders closing businesses not deemed essential and directing individuals to restrict their movements, observe social distancing and shelter in place. These actions, together with responses to the pandemic by businesses and individuals, have resulted in rapid decreases in commercial and consumer activity, temporary closures of many businesses that have led to a loss of revenues and a rapid increase in unemployment, material decreases in oil and gas prices and in business valuations, disrupted global supply chains, market downturns and volatility, changes in consumer behavior related to pandemic fears, related emergency response legislation and an expectation that Federal Reserve policy will maintain a low interest rate environment for the foreseeable future.

Legislative Developments

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security ("CARES") Act was signed into law. It contained substantial tax and spending provisions intended to address the impact of the COVID-19 pandemic. The CARES Act included the PPP, a nearly $350 billion program designed to aid small- and medium-sized businesses through federally guaranteed loans distributed through banks. These loans were intended to guarantee eight weeks of payroll and other costs to help those businesses remain viable and allow their workers to pay their bills. The initial $350 billion program was supplemented in late April 2020 with $310 billion in additional funding. On June 5, 2020, the Paycheck Protection Program Flexibility Act (the “new Act”) was signed into law, and made significant changes to the PPP to provide additional relief for small businesses. The new Act increased flexibility for small businesses that have been unable to rehire employees due to lack of employee availability, or have been unable to operate as normal due to COVID-19 related restrictions. It extended the period that businesses have to use PPP funds to qualify for loan forgiveness to 24 weeks, up from 8 weeks under the original rules. The new Act also relaxed the requirements that loan recipients must adhere to in order to qualify for loan forgiveness. In addition, the new Act extended the payment deferral period for PPP loans until the date when the amount of loan forgiveness is determined and remitted to the lender. For PPP recipients who do not apply for forgiveness, the loan deferral period is 10 months after the applicable forgiveness period ends. The new Act did not extend the period for new applicants to seek PPP loans, which closed on June 30, 2020.

We have partnered with a web-based commercial and SBA lending software provider to manage the origination, processing, closing and monitoring of SBA loans and have set up the Texas Capital Bank SBA PPP Loan Portal to provide borrowers the ability to apply and qualify for PPP loans. As of June 30, 2020, we had funded $717.5 million in PPP loans. We also implemented a short-term loan modification program in late March 2020 to provide temporary payment relief to borrowers who meet the program's qualifications. This program allows for a deferral of payments for 90 days, which we may extend for an additional 90 days, for a maximum of 180 days on a cumulative basis. The deferred payments along with interest accrued during the deferral period are due and payable on the maturity date of the existing loan. As of June 30, 2020, we have granted temporary modifications on 482 loans with a total outstanding loan balance of $1.2 billion, resulting in the deferral of $10.8 million in interest payments.

Impact on Our Financial Statements and Results of Operations

Financial institutions are dependent upon the ability of their loan customers to meet their loan obligations and the availability of their workforce and vendors. As a result of the shelter-at-home mandate that was in force early in the second quarter of 2020, commercial activity throughout the state of Texas, as well as nationally, decreased significantly. Most states have re-opened, albeit under limited capacities and under other social-distancing restrictions; however commercial activity has not returned to the levels existing prior to the outbreak of the pandemic. This decrease in commercial activity may result in our customers' inability to meet their loan obligations to us. In addition, the economic pressures and uncertainties related to the COVID-19 pandemic have resulted in changes in consumer spending behaviors, which may negatively impact the demand for loans and other services we offer. Our business and consumer customers are experiencing varying degrees of financial distress, which is expected to continue for the remainder of 2020, especially if positive cases increase and further economic shut-downs are mandated. Our borrowing base includes customers in industries such as energy, hotel/lodging, restaurants, entertainment, retail and commercial real estate, all of which have been and are likely to continue to be significantly impacted by the COVID-19 pandemic. We continue to monitor these customers closely.

Future economic conditions are subject to significant uncertainty. We have taken deliberate actions to ensure that we have the balance sheet strength to serve our clients and communities, including increases in liquidity and managing our assets and liabilities in order to maintain a strong capital position. Current economic pressures and their effects on our customers, coupled with the implementation of the CECL expected loss methodology for determining our allowance for credit losses, have contributed to substantially increased provision for credit losses for the first six months of 2020. We continue to monitor

Table of Contents

closely the impact of the COVID-19 pandemic on our customers, as well as the effects of the CARES Act and the new Act. Uncertainties associated with the pandemic include the duration of the outbreak, the impact to our customers, employees and vendors and the impact to the economy as a whole. COVID-19 has had, and is expected to continue to have, a significant adverse impact on our business, financial position and operating results. The extent to which the COVID-19 pandemic will impact our operations and financial results during the remainder of 2020 cannot be reasonably or reliably estimated at this time.

Impact on our Business Operations

In order to protect the health of our customers and employees, and to comply with applicable government directives, we have modified our business practices, including restricting employee travel, directing employees to work from home insofar as is possible and implementing our business continuity plans and protocols to the extent necessary. Since early March 2020, approximately 90% of our workforce has been working virtually with limited impact on the execution of our business and client experience. We expect to be able to continue with this strategy for the foreseeable future. When the decision is made to transition employees back into the office locations, our Business Continuity team has a plan in place to phase employees back into the office locations over an extended period of time. Our branch locations are currently open and operating during normal business hours, although customers are admitted into the branches only between the hours of 10:00 a.m. and 2:00 p.m. We are taking additional precautions within our branch locations, including enhanced cleaning procedures, to ensure the safety of our customers and our employees.

Energy Portfolio

Outstanding energy loans totaled $1.1 billion, or 4% of total loans, at June 30, 2020, compared to $1.4 billion at December 31, 2019 and $1.6 billion at June 30, 2019. Our energy loan portfolio is primarily comprised of loans to exploration and production (“E&P”) companies that are generally collateralized with proven reserves based on appropriate valuation standards that take into account the risk of oil and gas price volatility. At June 30, 2020, loans to E&P companies represented 84% of total energy loans outstanding. The majority of this portfolio consists of first lien, senior secured, reserve-based loans, which we believe is the lowest-risk form of energy lending. At June 30, 2020 approximately 40% of our exposure was located in lower cost production areas such as the Permian Basin and Eagle Ford.

We recorded $62.4 million in energy net charge-offs during the three months ended June 30, 2020, all of which were previously identified as problem loans that experienced further deterioration during the second quarter of 2020 exacerbated by the continued low commodity prices. Energy non-accruals totaled $103.9 million at June 30, 2020, $39.8 million of which relates to two loans that have been charged down to final resolution value and are expected to close in the third quarter of 2020, compared to $151.9 million at March 31, 2020 and $61.1 million at June 30, 2019.

We continue to proactively manage our energy portfolio and overall credit quality. Energy loans are reviewed quarterly and a formal borrowing base re-determination for reserve based loans is completed semi-annually to ensure that borrowing capacity is commensurate with asset values. Cash flows are assessed in the context of specific risk factors including commodity prices with corollary sensitivities, commodity hedges and select credit criteria. Reserves allocated to energy loans totaled $102.7 million, or 9% of outstanding energy loans, at June 30, 2020, compared to $113.9 million at March 31, 2020 and $48.1 million at June 30, 2019. At June 30, 2020 approximately 70% of our E&P clients are hedged 50% or more for 2020 and approximately 60% of our E&P clients are hedged 50% or more for 2021. We believe that this hedge coverage compares favorably to the energy downturn experienced in 2015 and 2016.

Results of Operations

Summary of Performance

We reported a net loss of $34.3 million and net loss available to common stockholders of $36.8 million for the second quarter of 2020 compared to net income of $77.8 million and net income available to common stockholders of $75.4 million for the second quarter of 2019. On a fully diluted basis, earnings/(loss) per common share were $(0.73) for the second quarter of 2020, compared to $1.50 for the second quarter of 2019. Return on average common equity (“ROE”) was (5.48)% and return on average assets ("ROA") was (0.36)% for the second quarter of 2020, compared to 12.18% and 1.05%, respectively, for the second quarter of 2019. The decline in net income, ROE and ROA for the second quarter of 2020 resulted primarily from a $73.0 million increase in the provision for credit losses, as well as a $80.6 million increase in non-interest expense, driven by the significant second quarter 2020 expenses described below.

Net loss and net loss available to common stockholders for the six months ended June 30, 2020 totaled $51.0 million and $55.9 million, respectively compared to net income and net income available to common stockholders of $159.5 million and $154.6 million, respectively, for the same period in 2019. On a fully diluted basis, earnings/(loss) per common share were $(1.11) for the six months ended June 30, 2020, compared to $3.07 for the same period in 2019. ROE was (4.16)% and ROA was (0.28)% for the six months ended June 30, 2020 compared to 12.77% and 1.14%, respectively, for the same period in 2019.

Details of the changes in the various components of net income are discussed below.

Net Interest Income

Net interest income was $209.9 million for the three months ended June 30, 2020 compared to $243.6 million for the same period in 2019. The decrease was primarily due to decreases in yields on earning assets and a shift in earning asset composition, offset by a decrease in funding costs. Average earning assets for the three months ended June 30, 2020 increased by $7.9 billion compared to the same period in 2019, including a $1.8 billion increase in average total loans held for investment, primarily from increases in average mortgage finance loans related to lower long-term interest rates, and an $8.2 billion increase in average liquidity assets, offset by a $2.1 billion decrease in average loans held for sale. The increase in average liquidity assets was the result of actions taken by management in the first half of 2020 to ensure that we have the balance sheet strength to serve our clients during the COVID-19 pandemic. While we intend to operate with above-average liquidity in response to the uncertain economic environment, we believe opportunities exist to improve core earnings by reducing or replacing higher-cost funding sources and improving the earning asset mix. The decrease in average loans held for sale compared to the second quarter of 2019 resulted from holding purchased loans for shorter durations than in prior periods in order to limit exposure to forbearance risk caused by current economic uncertainties. The resulting decline in net interest income on loans held for sale from shorter hold times was offset by an increase in non-interest income. Average interest-bearing liabilities increased for the three months ended June 30, 2020 compared to the same period in 2019 and included a $5.3 billion increase in average interest-bearing deposits, offset by a $406.0 million decrease in average other borrowings. Net interest margin for the three months ended June 30, 2020 was 2.30% compared to 3.41% for the same period in 2019. The decrease was primarily due to the effect of decreases in interest rates on earning asset yields, coupled with the shift in earning asset composition, primarily the increase in liquidity assets and decrease in loans held for sale, offset by lower funding costs compared to the second quarter of 2019.

The yield on total loans held for investment decreased to 3.88% for the three months ended June 30, 2020 compared to 5.15% for the same period in 2019, and the yield on earning assets decreased to 2.76% for the three months ended June 30, 2020 compared to 4.84% for the same period in 2019. The average cost of total deposits and borrowed funds decreased to 0.43% for the second quarter of 2020 from 1.48% for the second quarter of 2019. The spread on total earning assets, net of the cost of deposits and borrowed funds, was 2.33% for the second quarter of 2020 compared to 3.36% for the second quarter of 2019. The decrease was primarily a result of declining loan yields offset by a decrease in the cost of interest-bearing liabilities. Total funding costs, including all deposits, long-term debt and stockholders' equity, decreased to 0.45% for the second quarter of 2020 compared to 1.40% for 2019.

Net interest income was $438.2 million for the six months ended June 30, 2020 compared to $479.2 million for the same period in 2019. The decrease was primarily due to decreases in yields on earning assets and a shift in earning asset composition, offset by a decrease in funding costs. Average earning assets increased for the six months ended June 30, 2020 compared to the same period in 2019 and included a $1.8 billion increase in average total loans held for investment and a $6.4 billion increase in average liquidity assets, offset by a $551.1 million decrease in average loans held for sale. The increase in average liquidity assets was the result of deliberate actions taken by management as described above. The decrease in average loans held for sale was due to holding purchased loans for shorter durations as mentioned above. Average interest-bearing liabilities increased for the six months ended June 30, 2020 compared to the same period in 2019 and included a $4.5 billion increase in average interest-bearing deposits and a $96.6 million increase in average other borrowings. Net interest margin for the six months ended June 30, 2020 was 2.53% compared to 3.56% for 2019. The decrease was primarily due to the effect of decreases in interest rates on earning asset yields, coupled with the shift in earning asset composition, primarily the increase in liquidity assets and decrease in loans held for sale, offset by lower funding costs compared to the same period in 2019.

The yield on total loans held for investment decreased to 4.13% for the six months ended June 30, 2020 compared to 5.28% for the prior year period and the yield on earning assets decreased to 3.22% for the six months ended June 30, 2020 compared to 4.99% for the same period in 2019.

(1)	Other non-interest income includes such items as letter of credit fees, bank owned life insurance ("BOLI") income, dividends on FHLB and FRB stock, income from legal settlements and other general operating income.

Non-interest income increased by $46.1 million during the three months ended June 30, 2020 to $70.5 million, compared to $24.4 million for the same period in 2019. This increase was primarily due to a $45.0 million increase in net gain/(loss) on sale of loans held for sale, a $3.4 million increase in brokered loan fees and a $3.0 million increase in servicing income, partially offset by a $6.0 million decrease in other non-interest income. The increase in net gain/(loss) on sale of loans held for sale was due to favorable economics and lower hedge costs in the second quarter of 2020 as a result of holding purchased loans for shorter durations than in prior periods, which is offset by the decline in net interest income on loans held for sale noted above. The increase in brokered loan fees was due to an increase in total mortgage finance volumes during the three months ended June 30, 2020 compared to the same period in 2019, and the increase in servicing income was due to an overall increase in MSR balances held. The decrease in other non-interest income resulted primarily from $6.5 million in settlements of legal claims during the second quarter of 2019 not present in 2020.

Non-interest income increased by $27.9 million during the six months ended June 30, 2020 to $82.3 million, compared to $54.4 million for the same period in 2019. This increase was primarily due to a $32.5 million increase in net gain/(loss) on sale of loans held for sale, a $6.4 million increase in brokered loans fees and a $5.0 million increase in servicing income, partially offset by a $19.2 million decrease in other non-interest income. The increase in net gain/(loss) on sale of loans held for sale was due to favorable economics and lower hedge costs in 2020 as a result of holding purchased loans for shorter durations than in prior periods. The increase in brokered loan fees was due to an increase in total mortgage finance volumes during the six months ended June 30, 2020 compared to the same period in 2019, and the increase in servicing income was due to an overall increase in MSR balances held. The decrease in other non-interest income resulted primarily from $15.0 million in settlements of legal claims during the six months ended June 30, 2019 not present in 2020.

While management expects continued growth in certain components of non-interest income, the future rate of growth could be affected by increased competition from national and regional financial institutions and general economic conditions. In order to

Table of Contents

achieve continued growth in non-interest income, management from time to time evaluates new products, new lines of business or the expansion of existing lines of business. Any new product introduction or new market entry could place additional demands on capital and managerial resources and introduce new risks to our business.

Non-interest expense for the three months ended June 30, 2020 increased $80.6 million compared to the same period in 2019. The increase was primarily due to increases in salaries and employee benefits, communications and technology expenses, servicing-related expenses and merger-related expenses. The increases in salaries and employee benefits and communications and technology expense were primarily due to $18.0 million in severance accruals and $26.6 million in non-recurring software expenses; including $20.7 million in write-offs of certain software assets and $5.9 million in technology expense related to the roll-out of our PPP capability, respectively, mentioned above. The increase in servicing-related expenses was primarily due to higher MSR amortization expense resulting from an increase in the cost basis of our MSR asset as well as from higher mortgage prepayment rates, and an increase in impairment expense.

Mortgage finance loans relate to our mortgage warehouse lending operations in which we purchase mortgage loan ownership interests that are typically sold within 10 to 20 days and represent 36% of total loans held for investment at June 30, 2020, an increase compared to 33% at December 31, 2019. Volumes fluctuate based on the level of market demand for the product and the number of days between purchase and sale of the loans, which can be affected by changes in overall market interest rates and tend to peak at the end of each month. Traditional loans held for investment also increased during the first six months of 2020. The majority of the loan growth was in our real estate portfolio, offset by a decline in our energy portfolio. We continue

the strategy of planned reductions in portfolios that have experienced higher historic losses, primarily energy and leveraged lending.

We originate a substantial majority of all loans held for investment. We also participate in syndicated loan relationships, both as a participant and as an agent. As of June 30, 2020, we had $2.1 billion in syndicated loans, $464.6 million of which we administer as agent. All syndicated loans, whether we act as agent or participant, are underwritten to the same standards as all other loans we originate. As of June 30, 2020, $4.1 million of our syndicated loans were on non-accrual.

Portfolio Geographic and Industry Concentrations

Although more than 50% of our total loan exposure is outside of Texas and more than 50% of our deposits are sourced outside of Texas, our Texas concentration remains significant. As of June 30, 2020, a majority of our loans held for investment, excluding mortgage finance loans and other national lines of business, were to businesses with headquarters or operations in Texas. This geographic concentration subjects the loan portfolio to the general economic conditions within this state. We also make loans to customers that are secured by assets located outside of Texas. The risks created by this concentration have been considered by management in the determination of the appropriateness of the allowance for credit losses.

(1)	As of June 30, 2020, December 31, 2019 and June 30, 2019, non-accrual loans included $23.7 million, $35.1 million and $32.0 million, respectively, in loans that met the criteria for restructured.


(2)	At June 30, 2020, December 31, 2019 and June 30, 2019, loans past due 90 days and still accruing includes premium finance loans of $14.8 million, $8.5 million and $9.8 million, respectively.

Includes loans guaranteed by U.S. government agencies that were repurchased out of Ginnie Mae securities. Loans are recorded as loans held for sale and carried at fair value on the balance sheet. Interest on these past due loans accrues at the debenture rate guaranteed by the U.S. government. Also includes loans that, pursuant to Ginnie Mae servicing guidelines, we have the unilateral right, but not the obligation, to repurchase if defined delinquent loan criteria are met and therefore must record as loans held for sale on our balance sheet regardless of whether the repurchase option has been exercised.

Total non-performing assets at June 30, 2020 decreased $51.4 million from December 31, 2019 and increased $59.9 million compared to June 30, 2019. The decrease from December 31, 2019 was primarily related to charge-offs of energy and leveraged lending loans during the first six months of 2020. The year-over-year increase is primarily related to our energy and leveraged lending portfolios. Non-accrual energy loans totaled $103.9 million (60% of total NPAs) at June 30, 2020, $39.8 million of which relates to two loans that have been charged down to final resolution value and are expected to close in the third quarter of 2020, compared to $61.1 million at June 30, 2019. Non-accrual leveraged lending loans totaled $24.8 million (14% of total NPAs) at June 30, 2020 compared to $25.0 million at June 30, 2019. The COVID-19 pandemic has had an

adverse effect on our non-performing assets and, based on the current trajectory, we anticipate that continued adverse impacts will occur in subsequent quarters.

Potential problem loans consist of loans that are performing in accordance with contractual terms, but for which we have concerns about the borrower’s ability to comply with repayment terms because of the borrower’s potential financial difficulties. We monitor these loans closely and review their performance on a regular basis. At June 30, 2020, we had $132.0 million in loans of this type, compared to $46.6 million at December 31, 2019 and $44.9 million at June 30, 2019.

Summary of Credit Loss Experience

The provision for credit losses, which includes a provision for losses on unfunded commitments, is a charge to earnings to maintain the allowance for credit losses at a level consistent with management’s assessment of expected losses in the loan portfolio at the balance sheet date. We adopted ASU 2016-13 on January 1, 2020, which replaced the incurred loss methodology for determining our provision for credit losses and allowance for credit losses with the Current Expected Credit Loss ("CECL") model. Upon adoption, the allowance for credit losses was increased by $9.1 million, with no impact on the consolidated statement of income. We recorded a $100.0 million provision for credit losses for the second quarter of 2020, compared to $96.0 million in the first quarter of 2020 and $27.0 million in the second quarter of 2019. The increase resulted primarily from an increase in charge-offs and reserve build related to higher criticized loan levels and continued economic uncertainty related to the COVID-19 pandemic. We recorded $74.1 million in net charge-offs during the second quarter of 2020, including $62.4 million in energy net charge-offs and $8.1 million in leveraged lending net charge-offs, compared to $57.7 million during the first quarter of 2020 and $20.0 million during the second quarter of 2019. Criticized loans totaled $1.0 billion at June 30, 2020, compared to $675.9 million at March 31, 2020 and $629.1 million at June 30, 2019. The increase in criticized loans was predominantly in special mention and was primarily related to the continued downgrade of loans to borrowers that have been impacted by COVID-19 or that are in industries that are expected to be more significantly impacted by COVID-19.

The allowance for credit losses, including the allowance for losses on unfunded commitments reported on the consolidated balance sheets in other liabilities, totaled $277.0 million at June 30, 2020, $203.7 million at December 31, 2019 and $225.4 million at June 30, 2019. The combined allowance as a percentage of loans held for investment increased to 1.09% at June 30, 2020 from 0.83% at December 31, 2019 and 0.93% at June 30, 2019. The combined allowance as a percentage of loans held for investment, excluding mortgage finance, increased to 1.67% at June 30, 2020 from 1.24% at December 31, 2019 and 1.33% at June 30, 2019. The increase in the combined allowance as a percentage of loans held for investment at June 30, 2020 compared to June 30, 2019 is due primarily to an increase in the allowance for credit losses, resulting from reserve build related to higher criticized loan levels and continued economic uncertainty related to the COVID-19 pandemic.

Loans Held for Sale

Through our MCA program we commit to purchase residential mortgage loans from independent correspondent lenders and deliver those loans into the secondary market via whole loan sales to independent third parties or in securitization transactions to Ginnie Mae and GSEs such as Fannie Mae and Freddie Mac. For additional information on our loans held for sale portfolio, see Note 5 - Certain Transfers of Financial Assets in the accompanying notes to the consolidated financial statements included elsewhere in this report.

Liquidity and Capital Resources

In general terms, liquidity is a measurement of our ability to meet our cash needs. Our objectives in managing our liquidity are to maintain our ability to meet loan commitments, repurchase investment securities or repay deposits and other liabilities in accordance with their terms, without an adverse impact on our current or future earnings. Our liquidity strategy is guided by policies, formulated and monitored by our senior management and our Asset and Liability Management Committee (“ALCO”), which take into account the demonstrated marketability of our assets, the sources and stability of our funding and the level of unfunded commitments. We regularly evaluate all of our various funding sources with an emphasis on accessibility, stability, reliability and cost-effectiveness. For the year ended December 31, 2019 and the six months ended June 30, 2020, our principal source of funding has been our customer deposits, supplemented by our short-term and long-term borrowings, primarily from federal funds purchased and FHLB borrowings, which are generally used to fund mortgage finance assets. We also rely on the availability of the mortgage secondary market provided by Ginnie Mae and the GSEs to support the liquidity of our mortgage finance assets.

In accordance with our liquidity strategy, deposit growth and increases in borrowing capacity related to our mortgage finance loans have resulted in accumulating liquidity assets in recent periods. Additionally, in the first six months of 2020 we significantly increased our liquidity assets to ensure that we have the balance sheet strength to serve our clients during the COVID-19 pandemic. The following table summarizes the composition of liquidity assets:



(in thousands except percentage data)	June 30, 2020			December 31, 2019			June 30, 2019
Federal funds sold and securities purchased under resale agreements	$	50,000		$	30,000		$	34,000
Interest-bearing deposits	9,490,044			4,233,766			3,446,902
Total liquidity assets	$	9,540,044		$	4,263,766		$	3,480,902
Total liquidity assets as a percent of:
Total loans held for investment	37.4		%	17.3		%	14.3		%
Total earning assets	26.9		%	13.5		%	12.0		%
Total deposits	31.6		%	16.1		%	15.1		%

Our liquidity needs to support growth in loans held for investment have been fulfilled primarily through growth in our core customer deposits. Our goal is to obtain as much of our funding for loans held for investment and other earning assets as possible from deposits of these core customers. These deposits are generated principally through development of long-term customer relationships, with a significant focus on treasury management products. In addition to deposits from our core customers, we also have access to deposits through brokered customer relationships. For regulatory purposes, these relationship brokered deposits are categorized as brokered deposits; however, since these deposits arise from a customer relationship, which involves extensive treasury services, we consider these deposits to be core deposits for our reporting purposes.

Table of Contents

We also have access to incremental deposits through brokered retail certificates of deposit, or CDs. These traditional brokered deposits are generally of short maturities and are used to fund temporary differences in the growth in loan balances, including growth in loans held for sale or other specific categories of loans as compared to customer deposits. The following table summarizes our period-end and average core customer deposits, relationship brokered deposits and traditional brokered deposits:

(1) Annual averages presented for December 31, 2019.

We have access to sources of traditional brokered deposits that we estimate to be $7.5 billion. Based on our internal guidelines, we have chosen to limit our use of these sources to a lesser amount. We have increased our use of traditional brokered deposits in 2019 and 2020 in response to favorable rates available in that market relative to other available funding sources.

We have short-term borrowing sources available to supplement deposits and meet our funding needs. Such borrowings are generally used to fund our mortgage finance loans, due to their liquidity, short duration and interest spreads available. These borrowing sources include federal funds purchased from our downstream correspondent bank relationships (which consist of banks that are smaller than our Bank) and from our upstream correspondent bank relationships (which consist of banks that are larger than our Bank), customer repurchase agreements and advances from the FHLB and the Federal Reserve. The following table summarizes our short-term and other borrowings:

Our equity capital averaged $2.8 billion for the three months ended June 30, 2020 as compared to $2.6 billion for the same period in 2019. We have not paid any cash dividends on our common stock since we commenced operations and have no plans to do so in the foreseeable future.

Critical Accounting Policies

SEC guidance requires disclosure of “critical accounting policies.” The SEC defines “critical accounting policies” as those that are most important to the presentation of a company’s financial condition and results, and require management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

We follow financial accounting and reporting policies that are in accordance with accounting principles generally accepted in the United States. The more significant of these policies are summarized in Note 1 - Operations and Summary of Significant Accounting Policies in the notes to the consolidated financial statements included elsewhere in this report and in our 2019 Form 10-K. Not all significant accounting policies require management to make difficult, subjective or complex judgments. However, the policy noted below could be deemed to meet the SEC’s definition of a critical accounting policy.

Allowance for Credit Losses

Management considers the policies related to the allowance for credit losses as the most critical to the financial statement presentation. The total allowance for credit losses includes activity related to allowances calculated in accordance with Accounting Standards Codification (“ASC”) 326, Credit Losses. The allowance for credit losses is established through a provision for credit losses charged to current earnings. The amount maintained in the allowance reflects management’s continuing evaluation of the loan losses expected to be recognized over the life of the loans in our portfolio. The allowance for credit losses is a valuation account that is deducted from the loans' amortized cost basis to present the net amount expected to be collected on the loans. For purposes of determining the allowance for credit losses, the loan portfolio is segregated by product types in order to recognize differing risk profiles among categories, and then further segregated by credit grades. Loans that do not share risk characteristics are evaluated on an individual basis and are not included in the collective evaluation. Management estimates the allowance balance using relevant available information from internal and external sources relating to past events, current conditions and reasonable and supportable forecasts. Adjustments to historical loss information are made to incorporate our reasonable and supportable forecast of future losses at the portfolio segment level, as well as any necessary qualitative adjustments using a Portfolio Level Qualitative Factor ("PLQF") and/or a Portfolio Segment Level Qualitative Factor ("SLQF"). The PLQF and SLQF are utilized to address factors that are not present in historical loss rates and are otherwise unaccounted for in the quantitative process. A reserve is recorded upon origination or purchase of a loan. See “Summary of Credit Loss Experience” above and Note 4 – Loans Held for Investment and Allowance for Credit Losses on Loans in the accompanying notes to the consolidated financial statements included elsewhere in this report for further discussion of the risk factors considered by management in establishing the allowance for credit losses.

ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Market risk is a broad term for the risk of economic loss due to adverse changes in the fair value of a financial instrument. These changes may be the result of various factors, including interest rates, foreign exchange rates, commodity prices, or equity prices. Additionally, the financial instruments subject to market risk can be classified either as held for trading purposes or held for other than trading.

We are subject to market risk primarily through the effect of changes in interest rates on our portfolio of assets held for purposes other than trading. Additionally, we have some market risk relative to commodity prices through our energy lending activities. Declines and volatility in commodity prices negatively impacted our energy clients' ability to perform on their loan obligations in recent years, and further uncertainty and volatility could have a negative impact on our customers and our loan portfolio in future periods. Foreign exchange rates, commodity prices (other than energy) and equity prices are not expected to pose significant market risk to us.

The responsibility for managing market risk rests with the ALCO, which operates under policy guidelines established by our board of directors. The acceptable negative variation in net interest revenue due to a 100 basis point increase or decrease in interest rates is generally limited by these guidelines to plus or minus 10-12%. These guidelines establish maximum levels for short-term borrowings, short-term assets and public and brokered deposits and minimum levels for liquidity, among other things. Oversight of our compliance with these guidelines is the ongoing responsibility of the ALCO, with exceptions reported to the Risk Management Committee, and to our board of directors if deemed necessary, on a quarterly basis. Additionally, the Credit Policy Committee ("CPC") specifically manages risk relative to commodity price market risks. The CPC establishes maximum portfolio concentration levels for energy loans as well as maximum advance rates for energy collateral.

Interest Rate Risk Management

Our interest rate sensitivity is illustrated in the following table. The table reflects rate-sensitive positions as of June 30, 2020, and is not necessarily indicative of positions on other dates. The balances of interest rate sensitive assets and liabilities are presented in the periods in which they next reprice to market rates or mature and are aggregated to show the interest rate sensitivity gap. The mismatch between repricings or maturities within a time period is commonly referred to as the “gap” for that period. A positive gap (asset sensitive), where interest rate-sensitive assets exceed interest rate sensitive liabilities, generally will result in the net interest margin increasing in a rising rate environment and decreasing in a falling rate environment. A negative gap (liability sensitive) will generally have the opposite results on the net interest margin. To reflect anticipated prepayments, certain asset and liability categories are shown in the table using estimated cash flows rather than contractual cash flows. The Company employs interest rate floors in certain variable rate loans to enhance the yield on those loans at times when market interest rates are extraordinarily low. The degree of asset sensitivity, spreads on loans and net interest margin may be reduced until rates increase by an amount sufficient to eliminate the effects of floors. The adverse effect of floors as market rates increase may also be offset by the positive gap, the extent to which rates on deposits and other funding sources lag increasing market rates for loans and changes in composition of funding.

While a gap interest table is useful in analyzing interest rate sensitivity, an interest rate sensitivity simulation provides a better illustration of the sensitivity of earnings to changes in interest rates. Earnings are also affected by the effects of changing interest rates on the value of funding derived from demand deposits and stockholders’ equity. We perform a sensitivity analysis to identify interest rate risk exposure on net interest income. We quantify and measure interest rate risk exposure using a model to dynamically simulate the effect of changes in net interest income relative to changes in interest rates over the next twelve months based on three interest rate scenarios. These are a static rate scenario and two “shock test” scenarios.

These scenarios are based on interest rates as of the last day of a reporting period published by independent sources and incorporate relevant spreads of instruments that are actively traded in the open market. The Federal Reserve’s federal funds target affects short-term borrowing; the prime lending rate and LIBOR are the basis for most of our variable-rate loan pricing. The 10-year treasury rate is also monitored because of its effect on prepayment speeds for mortgage-backed securities and MSRs. These are our primary interest rate exposures. We are currently not using derivatives to manage our interest rate exposure although we may do so in the future if that appears advisable.

For modeling purposes, the “shock test” scenarios as of June 30, 2019 assume immediate, sustained 100 and 200 basis point increases in interest rates and a 100 basis point decrease in interest rates. As short-term rates have declined during the first six months of 2020, we do not believe that analysis of an assumed decrease in interest rates would provide meaningful results. As such, the scenarios as of June 30, 2020 assume immediate, sustained 100 and 200 basis point increases only. We will continue to evaluate these scenarios as interest rates change, until short-term rates rise above 3.0%, at which point we will resume evaluations of shock scenarios in which interest rates decrease.

Table of Contents

Our interest rate risk exposure model incorporates assumptions regarding the level of interest rate on indeterminable maturity deposits (demand deposits, interest-bearing transaction accounts and savings accounts) for a given level of market rate change. In the current environment of decreasing short-term rates, deposit pricing can vary by product and customer. These assumptions have been developed through a combination of historical analysis and projection of future expected pricing behavior. Changes in prepayment behavior of mortgage-backed securities, residential and commercial mortgage loans in each rate environment are captured using industry estimates of prepayment speeds for various coupon segments of the portfolio. The impact of these changes is factored into the simulation model. This modeling indicated interest rate sensitivity as follows:



	Anticipated Impact Over the Next Twelve Months as Compared to Most Likely Scenario
	June 30, 2020				June 30, 2019
(in thousands)	100 bps Increase		200 bps Increase		100 bps Increase		200 bps Increase		100 bps Decrease
Change in net interest income	$	70,160	$	152,756	$	101,238	$	202,841	$	(114,060	)

The simulations used to manage market risk are based on numerous assumptions regarding the effect of changes in interest rates on the timing and extent of repricing characteristics, future cash flows and customer behavior. These assumptions are inherently uncertain and, as a result, the model cannot precisely estimate net interest income or precisely predict the impact of higher or lower interest rates on net interest income. Actual results will differ from simulated results due to timing, magnitude and frequency of interest rate changes as well as changes in market conditions, customer behavior and management strategies, among other factors.

Our business relies upon a large volume of loans, derivative contracts and other financial instruments with attributes that are either directly or indirectly dependent on LIBOR to establish their interest rate and/or value. In 2017, the U.K. Financial Conduct Authority announced that it would no longer compel banks to submit rates for the calculation of LIBOR after 2021. The impact of alternatives to LIBOR on the valuations, pricing and operation of our financial instruments is not yet known; however, the primary instruments that may be impacted include loans, securities, borrowings and derivatives indexed to LIBOR that mature after December 31, 2021. We have established a working group, consisting of key stakeholders from throughout the Bank, to monitor developments relating to LIBOR uncertainty and changes and to guide the Bank's response. This team is currently working to gain an understanding of the specific products, information technology systems, borrowing arrangements and legal agreements that will be impacted by the change.

ITEM 4.	CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the supervision and participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of the end of the period covered by this report. Based upon that evaluation, we have concluded that, as of the end of such period, our disclosure controls and procedures were effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by us in the reports that we file or submit under the Exchange Act and were effective in ensuring that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to the Company's management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(e) and 15d-15(f) under the Exchange Act) during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION


ITEM 1.	LEGAL PROCEEDINGS

The Company is subject to various claims and legal actions that may arise in the ordinary course of conducting its business. Management does not expect the disposition of any of these matters to have a material adverse impact on the Company’s financial statements or results of operations.


ITEM 1A.	RISK FACTORS

We have described in our Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 Form 10-K”) the primary risks related to our business and securities and periodically update those risks. Provided below is an update to our risk factors as previously disclosed in the 2019 Form 10-K.

The novel Coronavirus Disease 2019 ("COVID-19") pandemic is adversely affecting us and our customers, employees and third-party service providers, and the adverse impacts on our business, financial position, operations and prospects have been and are expected to continue to be significant.

The spread of COVID-19 has created a global public health crisis that has resulted in unprecedented uncertainty, volatility and disruption in financial markets and in governmental, commercial and consumer activity in the United States and globally. Governmental responses to the pandemic have included orders closing businesses not deemed essential and directing individuals to restrict their movements, observe social distancing and shelter in place. These actions, together with responses to the pandemic by businesses and individuals, have resulted in rapid decreases in commercial and consumer activity, temporary closures of many businesses that have led to loss of revenues and a rapid increase in unemployment, material decreases in oil and gas prices and in business valuations, disrupted global supply chains, market downturns and volatility, changes in consumer behavior related to pandemic fears, related emergency response legislation and an expectation that Federal Reserve policy will maintain a low interest rate environment for the foreseeable future. These changes have a significant adverse effect on the markets in which we conduct our business and the demand for our products and services.

Business and consumer customers of the Bank are experiencing varying degrees of financial distress, which is expected to increase over coming months and will likely adversely affect their ability to timely pay interest and principal on their loans and the value of the collateral securing their obligations. This in turn has influenced the recognition of credit losses in our loan portfolios and has increased our allowance for credit losses, particularly as businesses remain closed and as more customers are expected to draw on their lines of credit or seek additional loans to help finance their businesses. Disruptions to our customers' businesses could also result in declines in, among other things, wealth management revenue. These developments as a consequence of the pandemic are materially impacting our business and the businesses of our customers and are expected to have a material adverse effect on our financial results for 2020, as evidenced by our first and second quarter results.

In order to protect the health of our customers and employees, and to comply with applicable government directives, we have modified our business practices, including restricting employee travel, directing employees to work from home insofar as is possible, cancelling in-person meetings and implementing our business continuity plans and protocols to the extent necessary. We may take further such actions that we determine are in the best interest of our employees, customers and communities or as may be required by government order. These actions in response to the COVID-19 pandemic, and similar actions by our vendors and business partners, have not materially impaired our ability to support our employees, conduct our business and serve our customers, but there is no assurance that these actions will be sufficient to successfully mitigate the risks presented by

COVID-19 or that our ability to operate will not be materially affected going forward. For instance, our business operations may be disrupted if key personnel or significant portions of our employees are unable to work effectively, including because of illness, quarantines, government actions, or other restrictions in connection with the COVID-19 pandemic. Similarly, if any of our vendors or business partners become unable to continue to provide their products and services, which we rely upon to maintain our day-to-day operations, our ability to serve our customers could be impacted.

COVID-19 does not yet appear to be contained and could affect significantly more households and businesses. Given the ongoing and dynamic nature of the circumstances, it is not possible to accurately predict the extent, severity or duration of these conditions or when normal economic and operating conditions will resume. For this reason, the extent to which the COVID-19 pandemic affects our business, operations and financial condition, as well as our regulatory capital and liquidity ratios and credit ratings, is highly uncertain and unpredictable and depends on, among other things, new information that may emerge concerning the scope, duration and severity of the COVID-19 pandemic and actions taken by governmental authorities and other parties in response to the pandemic. If the pandemic is prolonged, the adverse impact on the markets in which we operate and on our business, operations and financial condition is likely to deepen.

Material risks relating to our business that are enhanced due to the COVID-19 pandemic are addressed at Item 1A Risk Factors in the 2019 Form 10-K under the headings:


•	We must effectively manage our credit risk.


•	A significant portion of our assets consists of commercial loans.


•	A significant portion of our loans are secured by commercial and residential real estate.


•	Our future profitability depends, to a significant extent, upon our middle market business customers.


•	We must maintain an appropriate allowance for credit losses.


•	Changes in accounting standards, including the implementation of Current Expected Credit Loss methodology for 2020, could materially affect how we report our financial results.


•	Our business is concentrated in Texas; our energy industry exposure could adversely affect our performance.


•	Our business faces unpredictable economic and business conditions.


•	Our growth plans are dependent on the availability of capital and funding.


•	We must effectively manage our liquidity risk.


•	We, our vendors and customers must effectively manage our information systems risk.


•	Our operations rely extensively on a broad range of external vendors.


•	We must effectively manage our interest rate risk.


•	Our risk management strategies and processes may not be effective; our controls and procedures may fail or be circumvented.


•	We must effectively manage counterparty risk.


•	We must maintain adequate regulatory capital to support our business objectives.


•	We are dependent on funds obtained from borrowing or capital transactions or from our Bank to fund our operations.
