TEXAS CAPITAL BANCSHARES, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—UNAUDITED
(1) OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Organization and Nature of Business
Texas Capital Bancshares, Inc. (the “Company”), 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 and national clienteleclientèle of commercial borrowers. We are primarily a secured lender, with our greatest concentration of loans in Texas.
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 have been prepared without audit. 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, 2015, included in our Annual Report on Form 10-K filed with the SEC on February 18, 2016 (the “2015 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.
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 loan losses, the fair value of stock-based compensation awards, the fair values of financial instrumentscertain assets and liabilities and the status of contingencies are particularly susceptible to significant change in the near term.

(3) SECURITIES
At March 31,September 30, 2016, our net unrealized gain on the available-for-sale securities portfolio was $1.1 million$985,000 compared to $1.1 million at December 31, 2015. As a percent of outstanding balances, the unrealized gain was 3.90%3.88% and 3.83% at March 31,September 30, 2016, and December 31, 2015, respectively. The increase in the unrealized gain percentage at March 31,September 30, 2016 is related toresults from the reduction in the portfolio balance due to paydowns and maturities.

At March 31,September 30, 2016, we owned one security with an unrealized loss position. This security is a publicly traded equity fund and is subject to market pricing volatility. We do not believe this unrealized loss is “other-than-temporary”. We have evaluated the near-term prospects of the investment in relation to the severity and duration of the impairment and based on that evaluation have the ability and intent to hold the investment until recovery of fair value.

Commercial Loans and Leases. Our commercial loan portfolio is comprised of lines of credit for working capital and term loans and leases to finance equipment and other business assets. Our energy production loans are generally collateralized with proven reserves based on appropriate valuation standards and take into account the risk of oil and gas price volatility. Our commercial loans and leases are underwritten after carefully evaluating and understanding the borrower’s ability to operate profitably. Our underwriting standards are designed to promote relationship banking rather than to make loans on a transaction basis. Our lines of credit typically are limited to a percentage of the value of the assets securing the line. Lines of credit and term loans typically are reviewed annually, or more frequently, as needed, and are supported by accounts receivable, inventory, equipment and other assets of our clients’ businesses.
Mortgage Finance Loans. Our mortgage finance loans consist of ownership interests purchased in single-family residential mortgages funded through our mortgage finance group. These loans are typically held on our balance sheet for 10 to 20 days. We have agreements with mortgage lenders and purchase interests in individual loans they originate. All loans are underwritten consistent with established programs for permanent financing with financially sound investors. Substantially all loans are conforming loans. March 31,September 30, 2016 and December 31, 2015 balances are stated net of $515.4 million$1.0 billion and $454.8 million participations sold, respectively.
Construction Loans. Our construction loan portfolio consists primarily of single- and multi-family residential properties and commercial projects used in manufacturing, warehousing, service or retail businesses. Our construction loans generally have terms of one to three years. We typically make construction loans to developers, builders and contractors that have an established record of successful project completion and loan repayment and have a substantial equity investment in the borrowers. Loan amounts are derived primarily from the Bank's evaluation of expected cash flows available to service debt from stabilized projects under hypothetically stressed conditions. Construction loans are also based in part upon estimates of costs and value associated with the completed project. Sources of repayment for these types of loans may be pre-committed permanent loans from other lenders, sales of developed property, or an interim loan commitment from us until permanent financing is obtained. The nature of these loans makes ultimate repayment sensitive to overall economic conditions. Borrowers may not be able to correct conditions of default in loans, increasing risk of exposure to classification, non-performing status, reserve allocation and actual credit loss and foreclosure. These loans typically have floating rates and commitment fees.
Real Estate Loans. A portion of our real estate loan portfolio is comprised of loans secured by properties other than market risk or investment-type real estate. Market risk loans are real estate loans where the primary source of repayment is expected to come from the sale, permanent financing or lease of the real property collateral. We generally provide temporary financing for commercial and residential property. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Our real estate loans generally have maximum terms of five to seven years, and we provide loans with both floating and fixed rates. We generally avoid long-term loans for commercial real estate held for investment. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. Appraised values may be highly variable due to market conditions and the impact of the inability of potential purchasers and lessees to obtain financing and a lack of transactions at comparable values.

At March 31,September 30, 2016 and December 31, 2015, we had a blanket floating lien on certain real estate-secured loans, mortgage finance loans and certain securities used as collateral for Federal Home Loan Bank (“FHLB”) borrowings.
Summary of Loan Loss Experience
The allowance for loan losses is comprised of specific reserves for impaired loans and an additional qualitative reserve based on our estimate of losses inherent in the portfolio at the balance sheet date, but not yet identified with specified loans. We consider the allowance at March 31,September 30, 2016 to be appropriate, given management's assessment of potential losses inherent in the portfolio as of the evaluation date, the significant growth in the loan and lease portfolio, current economic conditions in our market areas and other factors.
The following tables summarize the credit risk profile of our loan portfolio by internally assigned grades and non-accrual status as of March 31,September 30, 2016 and December 31, 2015 (in thousands):

We have traditionally maintained an additional qualitative reserve component to compensate for the uncertainty and complexity in estimating loan and lease losses including factors and conditions that may not be fully reflected in the determination and application of the allowance allocation percentages. We believe the level of additional qualitative reservesreserve at March 31,September 30, 2016 is warranted due to the continued uncertain economic environment which has produced losses, including those resulting from borrowers' misstatement of financial information or inaccurate certification of collateral values. Such losses are not necessarily correlated with historical loss trends or general economic conditions. Our methodology used to calculate the allowance considers historical losses; however, the historical loss rates for specific product types or credit risk grades may not fully incorporate the effects of continued weakness in the economy and continued volatility in the energy sector.


Our recorded investment in loans as of March 31,September 30, 2016, December 31, 2015 and March 31,September 30, 2015 related to each balance in the allowance for loan losses by portfolio segment and disaggregated on the basis of our impairment methodology was as follows (in thousands):

Generally we place loans 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. Interest income is subsequently recognized on a cash basis as long as the remaining unpaid principal amount of the loan is deemed to be fully collectible. If collectability is questionable, then cash payments are applied to principal. As of March 31,September 30, 2016, $824,000$816,000 of our non-accrual loans were earning on a cash basis compared to $884,000 at December 31, 2015. 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.

A loan held for investment is considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due (both principal and interest) according to the terms of the original loan agreement. In accordance with ASC 310 Receivables ("ASC 310"), we have also included all restructured loans in our impaired loan totals. The following tables detail our impaired loans, by portfolio class, as of March 31,September 30, 2016 and December 31, 2015 (in thousands):

(1)Loans past due 90 days and still accruing includes premium finance loans of $6.1$7.1 million. These loans are generally secured by obligations of insurance carriers to refund premiums on canceled insurance policies. The refund of premiums from the insurance carriers can take 180 days or longer from the cancellation date.
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 the 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. At March 31,September 30, 2016, and December 31, 2015, had $249,000 inwe did not have any loans considered restructured that were not on non-accrual.non-accrual compared to $249,000 at December 31, 2015. These loans did not have unfunded commitments at March 31,September 30, 2016 or December 31, 2015. Of the non-accrual loans at March 31,September 30, 2016 and December 31, 2015, $37.9$19.7 million and $24.9 million, respectively, met the criteria for restructured. These loans had no unfunded commitments at their respective balance sheet dates. A loan continues to qualify as restructured until a consistent payment history or change in borrower’s financial condition has been evidenced, generally over no less than twelve months. Assuming that 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 no longer has to be considered a restructuring if it is in compliance with the modified terms in calendar years after the year of the restructure.

The restructured loans generally include terms to temporarily place loans on interest only, extend the payment terms or reduce the interest rate. We did not forgive any principal on the above loans. The restructuring of the loans did not have a significant impact on our allowance for loan losses at March 31,September 30, 2016 or 2015.

(6) CERTAIN TRANSFERS OF FINANCIAL ASSETS


Through our Mortgage Correspondent Aggregation ("MCA") business, we commit to purchase residential mortgage loans from correspondent lenders and deliver those loans into the secondary market via whole loan sales to independent third parties or in securitization transactions to government sponsored entities ("GSEs") such as Fannie Mae, Freddie Mac or Ginnie Mae. We have elected to carry these loans at fair value based on sales commitments and market quotes. Changes in the fair value of the loans held for sale are included in other non-interest income.
Residential mortgage loans are subject to both credit and interest rate risk. Credit risk is managed through underwriting policies and procedures, including collateral requirements, which are generally accepted by the secondary loan markets. Exposure to interest rate fluctuations is partially managed through forward sales contracts, which set the price for loans that will be delivered in the next 60 to 90 days.
The table below presents the unpaid principal balance of loans held for sale and related fair values at March 31,September 30, 2016 and December 31, 2015 (in thousands):

No loans held for sale were 90 days or more past due or considered impairedon non-accrual as of March 31,September 30, 2016 and December 31, 2015, and no credit losses were recognized on loans held for sale for the three months ended March 31, 2016.2015.
The differences between the fair value and the aggregate unpaid principal balance include changes in fair value recorded at and subsequent to purchase, gains and losses on the related loan purchase commitment prior to purchase and premiums or discounts on acquired loans.
We generally retain the right to service the loans sold, creating mortgage servicing rights ("MSRs") which are recorded as assets on our balance sheet. A summary of MSR activities for the threenine months ended March 31,September 30, 2016 is as follows (in thousands):

(1)Mortgage servicing rights are reported on the consolidated balance sheets at lower of cost or market. Carrying value and fair value were the same at December 31, 2015, respectively.
At March 31,September 30, 2016 and December 31, 2015, our servicing portfolio of residential mortgage loans sold included 1,4704,954 and 168 loans, respectively, with an outstanding principal balance of $380.2 million$1.3 billion and $39.0 million, respectively. In connection with the servicing of these loans, we maintain escrow funds for taxes and insurance in the name of investors, as well as collections in transit to investors. These escrow funds are segregated and held in separate non-interest-bearing bank accounts at the Bank. These deposits, included in total non-interest-bearing deposits on the consolidated balance sheets, were $2.9$18.5 million at March 31,September 30, 2016 and $240,000 at December 31, 2015.
For loans securitized

As of September 30, 2016 and sold for the three months ended MarchDecember 31, 2016 with servicing rights retained,2015, management used the following assumptions to determine the fair value of MSRs at the date of the securitization or sale:MSRs:
Average discount rates9.85%
Expected prepayment speeds10.67%
Weighted-average life, in years6.5


 September 30, 2016December 31, 2015
Average discount rates10.09%9.76%
Expected prepayment speeds11.18%9.66%
Weighted average life, in years6.5
7.3
In conjunction with the sale and securitization of loans held for sale, we may be exposed to liability resulting from recourse agreements and repurchase agreements. If it is determined subsequent to our sale of a loan that the loan sold is in breach of the representations or warranties made in the applicable sale agreement, we may have an obligation to either (a) repurchase the loan for the unpaid principal balance, accrued interest and related advances, (b) indemnify the purchaser against any loss it suffers or (c) make the purchaser whole for the economic benefits of the loan. During the threenine months ended March 31,September 30, 2016, we originated or purchased and sold approximately $342.6 million$1.4 billion of mortgage loans to GSEs.loans.
Our repurchase, indemnification and make whole obligations vary based upon the terms of the applicable agreements, the nature of the asserted breach and the status of the mortgage loan at the time a claim is made. We establish reserves for estimated losses of this nature inherent in the origination of mortgage loans by estimating the probable losses inherent in the population of all loans sold based on trends in claims and actual loss severities experienced. The reserve will include accruals for probable contingent losses in addition to those identified in the pipeline of claims received. The estimation process is designed to include amounts based on any actual losses experienced from actual repurchase activity.
Because the MCA business commenced in late 2015, we have no historical data to support the establishment of a reserve. The baseline for the repurchase reserve uses historical loss factors obtained from industry data that are applied to loan pools originated and sold from September 2015 through March 31,September 30, 2016. The historical industry data loss factors and experienced losses will beare accumulated for each sale vintage (year loan was sold) and applied to more recent sale vintages to estimate inherent losses not yet realized. Our estimated exposure related to these loans was $178,000$621,000 at March 31,September 30, 2016 and is recorded in other liabilities in the consolidated balance sheets. We had no losses due to repurchase, indemnification or make-whole obligations during the threenine months ended March 31, 2016.September 30, 2016 as it relates to our MCA program.
(7) FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK
The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit that involve varying degrees of credit risk in excess of the amount recognized in the consolidated balance sheets. The Bank’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the borrower.
Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s credit-worthiness on a case-by-case basis.
Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.
The table below summarizes our off-balance sheet financial instruments whose contract amounts represented credit risk (in thousands):

(8) REGULATORY MATTERS
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 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.

In July 2013, the Federal Reserve published final rules for the adoption of theThe Basel III regulatory capital framework applicable to the Company and the Bank (the "Basel III Capital Rules"). The Basel III Capital Rules, specifies, among other things, (i) introduced a new capital measure called "Common Equity Tier 1" ("CET1"), capital measure, (ii) specified thata Tier 1 capital consistmeasure consisting of CET1 and "Additional Tier 1 Capital" instruments meeting specified requirements, (iii) definedcapital conservation buffers with respect to each of the CET1, narrowly by requiringTier 1 risk-based and total risk-based capital ratios providing for capital levels that most deductions/adjustments to regulatoryexceed the minimum risk-based capital measures be made to CET1 and not to the other components of capitaladequacy requirements and (iv) expandeda Tier 1 leverage ratio requirement of 5.0%.
In order to be well capitalized under the scope of the deductions/adjustments as compared to existing regulations. The Basel III Capital Rules, became effective for usour Bank must maintain a CET1 capital ratio, Tier 1 capital ratio and total capital ratio of greater than or equal to 6.5%, 8.0% and 10.0%, respectively. The capital conservation buffers required by the Basel III Capital Rules are subject to a three year phase-in period that began on January 1, 2015 with certain transition provisions2016 and will be fully phased inphased-in on January 1, 2019.2019 at 2.5%. A financial institution with a conservation buffer of less than the required amount will be subject to limitations on capital distributions, including dividend payments and stock repurchases and executive bonus payments.
Quantitative measures established by these regulations 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 March 31,September 30, 2016, that the Company and the Bank met 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 capital, Tier 1 risk-based capital, 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 March 31,September 30, 2016, and December 31, 2015. 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 changes could result in reducing 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 bankBank 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.
The table below summarizes our capital ratios:

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 March 31,September 30, 2016, our total mortgage finance loans were $5.0 billion compared to the average for the quarter ended March 31,September 30, 2016 of $3.7$4.7 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, the quarter-end fluctuation in these balances can significantly impact our reported ratios. We manage capital allocated to mortgage finance loans based on changing trends in average balances, as well as the inherent risk associated with the assets which implies a risk weight that is significantly different than the regulatory risk weight, and do not believe that the quarter-end balance is representative of risk characteristics that would justify higher capital allocations. However, we continue to monitor our capital allocation to confirm that all capital levels remain above well-capitalized levels.
Dividends that may be paid by subsidiary banks are routinely restricted by various regulatory authorities. The amount that can be paid in any calendar year without prior approval of the 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.Bank. No dividends were declared or paid on common stock during the threenine months ended March 31,September 30, 2016 or 2015.
(9) STOCK-BASED COMPENSATION
We have stock-based compensation plans under which equity-based compensation grants are made by the board of directors, or its designated committee. Grants are subject to vesting requirements. Under the plans, we may grant, among other things, nonqualified stock options, incentive stock options, restricted stock units ("RSUs"), stock appreciation rights ("SARs"), cash-based performance units or any combination thereof. Plans include grants for employees and directors. TotalThere are 2,550,000 total shares authorized under the plans are 2,550,000.


plans.
The fair value of our option and stock appreciation right ("SAR") grants are estimated at the date of grant using the Black-Scholes option pricing model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because our employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide the best single measure of the fair value of employee stock options.
Stock-based compensation consists of SARs, RSUs and cash-based performance units granted from 2010 through March 31,September 30, 2016.

(10) FAIR VALUE DISCLOSURES
ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), defines fair value, establishes a framework for measuring fair value under GAAP and requires enhanced disclosures about fair value measurements. Fair value is defined under ASC 820 as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal market for the asset or liability in an orderly transaction between market participants on the measurement date.
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 1Quoted prices in active markets for identical assets or liabilities. This category includes the assets and liabilities related to our non-qualified deferred compensation plan where values are based on quoted market prices for identical equity securities in an active market.
Level 2Observable 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 2 assets include U.S. government and agency mortgage-backed debt securities, municipal bonds, and Community Reinvestment Act funds. This category includes loans held for sale and derivative assets and liabilities where values are obtained from independent pricing services.

bonds, and Community Reinvestment Act funds. This category includes loans held for sale and derivative assets and liabilities where values are obtained from independent pricing services.
Level 3Unobservable 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. This category also includes impaired loans, MSRs and OREO where collateral values have been based on third party appraisals; however, due to current economic conditions, comparative sales data typically used in appraisals may be unavailable or more subjective due to lack of market activity.


Assets and liabilities measured at fair value at March 31,September 30, 2016 and December 31, 2015 are as follows (in thousands):

Level 3 Valuations
Financial instruments are considered Level 3 when their values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. Level 3 financial instruments also include those for which the determination of fair value requires significant management judgment or estimation. Currently, we measure the fair value for certain loans and OREO on a nonrecurring basis as described below.
Loans held for investment
During threethe nine months ended March 31,September 30, 2016 and the year ended December 31, 2015, certain impaired loans held for investment were re-evaluated and reported at fair value through a specific allocation of the allowance for loan losses based upon the fair value of the underlying collateral. The $96.5$36.4 million reported fair value above includes impaired loans held for investment at March 31,September 30, 2016 with a carrying value of $127.8$61.7 million that were reduced by specific allowance allocations totaling $31.3$25.3 million based on collateral valuations utilizing Level 3 valuation inputs. The $41.4 million reported fair value above includes impaired loans held for investment at December 31, 2015 with a carrying value of $49.7 million that were reduced by specific valuation allowance allocations totaling $8.3 million based on collateral valuations utilizing Level 3 valuation inputs. Fair values were based on third party appraisals.
OREO
Certain foreclosed assets, upon initial recognition, are recorded at fair value less estimated selling costs. At March 31,September 30, 2016 and December 31, 2015, OREO had a carrying value of $17.6$19.0 million and $278,000, respectively, with no specific valuation allowance. The fair value of OREO was computed based on third party appraisals, which are Level 3 valuation inputs.

Fair Value of Financial Instruments
Generally accepted accounting principlesGAAP require 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 following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments:
Cash and cash equivalents
The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents approximate their fair value, and these financial instruments are characterized as Level 1 assets in the fair value hierarchy.
Securities


Securities, available-for-sale
Within the securities available-for-sale portfolio, we hold equity securities related to our non-qualified deferred compensation plan which are valued using quoted market prices for identical equity securities in an active market. These financial instruments are classified as Level 1 assets in the fair value hierarchy. The fair value of the remaining investment securitiesportfolio is based on prices obtained from independent pricing services which are based on quoted market prices for the same or similar securities, and these financial instruments are characterized as Level 2 assets in the fair value hierarchy. We have obtained documentation from the primary pricing service we use about their processes and controls over pricing. In addition, on a quarterly basis we independently verify the prices that we receive from the service provider using two additional independent pricing sources. Any significant differences are investigated and resolved.
Loans held for sale
Fair value for loans held for sale valued under the fair value option is derived from quoted market prices for similar loans, and these financial instruments are characterized as Level 2 assets in the fair value hierarchy.
Loans held for investment, net
Loans held for investment are characterized as Level 3 assets in the fair value hierarchy. For variable-rate loans held for investment that reprice frequently with no significant change in credit risk, fair values are generally based on carrying values. The fair value for all other loans held for investment is estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The carrying amount of accrued interest approximates its fair value.
Derivatives
The estimated fair value of the interest rate swaps and caps is obtained from independent pricing services based on quoted market prices for the same or similar derivative contracts and these financial instruments are characterized as Level 2 assets in the fair value hierarchy. On a quarterly basis, we independently verify the fair value using an additional independent pricing source. Any significant differences are investigated and resolved. The derivative instruments related to the loans held for sale portfolio include loan purchase commitments and forward sales 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.data for similar loans. Forward sales commitments are valued based upon the quoted market prices from brokers. As such, these loan purchase commitments and forward sales commitments are classified as Level 2 assets in the fair value hierarchy.
Deposits
Deposits are characterized as Level 3 liabilities in the fair value hierarchy. The carrying amounts for variable-rate money market accounts approximate their fair value. Fixed-term certificates of deposit fair values are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities.
Federal funds purchased, customer repurchase agreements, other borrowings, subordinated notes and trust preferred subordinated debentures
The carrying value reported in the consolidated balance sheets for Federal funds purchased, customer repurchase agreements and other short-term, floating rate borrowings approximates their fair value, and these financial instruments are characterized as Level 2 assets in the fair value hierarchy. The fair value of any fixed rate short-term borrowings and trust preferred subordinated debentures are estimated using a discounted cash flow calculation that applies interest rates currently being offered on similar borrowings, and these financial instruments are characterized as Level 3 liabilities in the fair value hierarchy. The subordinated notes are publicly, though infrequently, traded and are valued based on market prices, and are characterized as Level 2 liabilities in the fair value hierarchy.
(11) DERIVATIVE FINANCIAL INSTRUMENTS
The fair value of derivative positions outstanding is included in accrued interest receivable and other assets and other liabilities in the accompanying consolidated balance sheets on a net basis when a right of offset exists, based on transactions with a single counterparty that are subject to a legally enforceable master netting agreement.
During the three and nine months ended March 31,September 30, 2016 and 2015, we entered into certain interest rate derivative positions that were not designated as hedging instruments. These derivative positions relate to transactions in which we enter into an interest rate swap, cap and/or floor with a customer while at the same time entering into an offsetting interest rate swap, cap and/or floor with another financial institution. In connection with each swap transaction, we agree to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, we agree to pay another financial institution the same fixed interest rate on the same

notional amount and receive the same variable interest rate on the same notional amount. The transaction allows our customer to effectively convert a variable rate loan to a fixed rate. Because we act as an intermediary for our customer, changes in the fair value of the underlying derivative contracts substantially offset each other and do not have a material impact on our results of operations.
During the three and nine months ended March 31,September 30, 2016, we entered into loan purchase commitment contracts with mortgage originators to purchase residential mortgage loans at a future date, as well as forward sales commitment contracts to sell residential mortgage loans at a future date.

Our credit exposure on interest rate swaps and capsderivative instruments is limited to the net favorable value and interest payments of all swaps and caps by each counterparty. In such cases collateral may be required from the counterparties involved if the net value of the swaps and caps exceedsderivative instruments exceed a nominal amount considered to be immaterial. Our credit exposure, net of any collateral pledged, relating to interest rate swaps and caps was approximately $54.9$58.2 million at March 31,September 30, 2016 and approximately $35.3 million at December 31, 2015, all of which primarily relates to bankBank customers. Collateral levels are monitored and adjusted on a regular basis for changes in interest rate swap and cap values. At March 31,September 30, 2016, and December 31, 2015, we had $55.7$65.5 million and $37.1 million, respectively, in cash collateral pledged for these derivatives, of which $62.1 million was included in interest-bearing deposits and $3.4 million was included in accrued interest receivable and other assets. At December 31, 2015, we had $37.1 million in cash collateral pledged for these derivatives, all of which was included in interest-bearing deposits.


(12) NEW ACCOUNTING PRONOUNCEMENTS
ASU 2016-15 "Statement of Cash Flows (Topic 230)" ("ASU 2016-15") is intended to reduce the diversity in practice around how certain transactions are classified within the statement of cash flows. ASU 2016-15 is effective for public companies for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted with retrospective application. We are evaluating the impact adoption of ASU 2016-15 will have on our consolidated financial statements.
ASU 2016-13 "Financial Instruments - Credit Losses (Topic 326)" ("ASU 2016-13") requires an entity to utilize a new impairment model known as the current expected credit loss ("CECL") model to estimate its lifetime "expected credit loss" and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. ASU 2016-13 also requires new disclosures for financial assets measured at amortized cost, loans and available-for-sale debt securities. ASU 2016-13 is effective for public companies for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Entities will apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. We are in the process of evaluating the impact adoption of ASU 2016-13 will have on our consolidated financial statements and disclosures.
ASU 2016-09 "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payments Accounting" ("ASU 2016-09") amended guidance with the intent to simplify accounting for share-based payment transaction, including the income tax consequences and classification of awards. Among other items, the update requires excess tax benefits and deficiencies to be recognized as a component of income taxes within the income statement rather than other comprehensive income as required in current guidance. ASU 2016-09 is effective for public companies for annual periods beginning after December 31, 2016 and is not expected to have a significant impact on our financial statements.
ASU 2016-02 "Leases (Topic 842)" ("ASU 2016-02") requires that lessees and lessors recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. ASU 2016-02 is effective for public companies for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. We have not yet selected a transition method nor haveas we determinedare in the process of determining the effect of the standard on our financial statements and disclosures.


ASU 2015-03 "Interest - Imputation of Interest (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03") requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Prior to the issuance of ASU 2015-03, debt issuance costs were required to be presented as deferred charge assets, separate from the related debt liability. ASU 2015-03 does not change the recognition and measurement requirements for debt issuance costs. We adopted ASU 2015-03 effective January 1, 2016 and applied its provisions retrospectively. The adoption of ASU 2015-03 resulted in the reclassification of $5.2$5.0 million and $5.3 million of unamortized debt issuance costs related to our Subordinatedsubordinated notes from other assets to subordinated notes within the consolidated balance sheets as of March 31,September 30, 2016 and December 31, 2015.2015, respectively. Other than this reclassification, the adoption of ASU 2015-03 did not have a material impact on our consolidated financial statements.
ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" ("("ASU 2014-09") implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 establishes a five-step model which entities must follow to recognize revenue and removes inconsistencies and weaknesses in existing guidance. ASU 2014-09 was originally going to be effective for annual and interim periods beginning after December 15, 2016; however, the FASB issued ASU 2015-14 - "Revenue from Contracts with Customers (Topic 606) - Deferral of the Effective Date" which deferred the effective date of ASU 2014-09 by one year to annual and interim periods beginning after December 15, 2017. We are in the process of evaluating the impact adoption of ASU 2014-09 is not expected towill have a significant impact on our consolidated financial statements.statements and disclosures.

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 service and manage effectively 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.
In the third quarter of 2015, we launched a correspondent lending program, MCA, to complement our warehouse lending program. 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 GSEs such as Fannie Mae, Freddie Mac and Ginnie Mae. We retain the MSRs in some cases with the expectation that they will be sold from time to time. Once purchased, these loans are classified as held for sale and are carried at fair value pursuant to our election of the fair value option. At the commitment date, we enter into a corresponding forward sale commitment with a third party, typically a GSE, to deliver the loans to the GSEthird party within a specified timeframe. The estimated gain/loss for the entire transaction (from initial purchase commitment to final delivery of loans) is recorded as an asset or liability. Fair value is derived from observable current market prices, when available, and includes the fair value of the MSRs. At March 31,September 30, 2016 and December 31, 2015, we had $94.7$648.7 million and $86.1 million in loans held for sale related to MCA.
The following discussion and analysis presents the significant factors affecting our financial condition as of March 31,September 30, 2016 and December 31, 2015 and results of operations for the three and nine months in the periods ended March 31,September 30, 2016 and 2015. This discussion should be read in conjunction with our consolidated financial statements and notes to the financial statements appearing in Part I, Item 1 of this report.

Results of Operations
Summary of Performance
We reported net income of $25.1$42.7 million and net income available to common stockholders of $22.7$40.3 million, or $0.49$0.87 per diluted common share, for the firstthird quarter of 2016 compared to net income of $35.1$37.1 million and net income available to common stockholders of $32.6$34.7 million, or $0.70$0.75 per diluted common share, for the firstthird quarter of 2015.

The increase in ROE resulted from an increase in net interest income for the third quarter of 2016, despite a higher provision for credit losses. ROA remains low as a result of the increased provision for credit losses and higher liquidity assets. Net income and net income available to common stockholders for the nine months ended September 30, 2016 totaled $106.7 million and $99.4 million, respectively, or $2.14 per diluted common share, compared to net income and net income available to common stockholders of $110.1 million and $102.8 million, respectively, or $2.21 per diluted common share, for the same period in 2015. ROE was 8.70% and ROA was 0.70% for the nine months ended September 30, 2016 compared to 9.94% and 0.82%, respectively, for the nine months ended September 30, 2015. The ROE decrease resulted from the increased provision for credit losses. Return on average common equity (“ROE”) was 6.13% and return on average assets ("ROA") was 0.53% for the first quarter of 2016, compared to 9.82% and 0.84%, respectively, for the first quarter of 2015. The ROA decrease resulted from the increased provision for credit losses, as well as a combination of reduced yields on loans held for investment, excluding mortgage finance loans, and a $742.7$778.2 million increase in average liquidity assets during the threenine months ended March 31,September 30, 2016 compared to the same period of 2015.
Net income decreased $9.9increased $5.6 million, or 28%15%, for the three months ended March 31,September 30, 2016, as compared to the same period in 2015.

While management expects continued growth in certain components of non-interest income, the future rate of growth could be affected by increased competition from nationwide and regional financial institutions. In order to achieve growth in non-interest income, we may need to introduce new products or enter into new lines of business or expand existing lines of business. Any new product introduction or new market entry could place additional demands on capital and managerial resources.

Total loans held for investment net of allowance for loan losses at March 31,September 30, 2016 increased $307.8$872.3 million from December 31, 2015 to $16.9$17.4 billion. Our business plan focuses primarily on lending to middle market businesses and successful professionals and entrepreneurs, and as such, commercial, real estate and construction loans have comprised a majority of our loan portfolio. Consumer loans generally have represented 1% or less of the portfolio. Mortgage finance loans relate to our mortgage warehouse lending operations in which we invest in mortgage loan ownership interests that are typically sold within 10 to 20 days. Volumes fluctuate based on the level of market demand for the product and the number of days between purchase and sale of the loans as well as overall market interest rates and tend to peak at the end of each month.
We originate a substantial majority of all loans held for investment (excluding mortgage finance loans). We also participate in syndicated loan relationships, both as a participant and as an agent. As of March 31,September 30, 2016, we had $1.9$2.1 billion in syndicated loans, $372.2$548.4 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 March 31,September 30, 2016, $12.9$82.7 million of our syndicated loans were on non-accrual.
Portfolio Geographic Concentration
When considering our mortgage finance loans and other national lines of business, more than 50% of our borrowers and the value of collateral securing our loans held for investment are located outside of Texas. However, as of March 31,September 30, 2016, a majority of our loans held for investment, excluding our mortgage finance loans and other national lines of business, were to businesses with headquarters and operations in Texas. This geographic concentration subjects the loan portfolio to the general economic conditions within this area. We also make loans to these 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 adequacy of the allowance for loan losses.
Summary of Loan Loss Experience
The provision for credit losses is a charge to earnings to maintain the allowance for loan losses at a level consistent with management’s assessment of the collectability of the loan portfolio in light of current economic conditions and market trends. We recorded a provision of $30.0$22.0 million during the firstthird quarter of 2016 compared to $11.0$13.8 million in the firstthird quarter of 2015 and $14.0$16.0 million in the fourthsecond quarter of 2015.2016. The increase in provision recorded during the firstthird quarter of 2016 compared to the same period in 2015 is related to the deterioration in our energy portfolio, as well as growth in loans held for investment, excluding mortgage finance loans, and

an increase in total criticized loans, as well as changes in applied risk weights. Risk weights are based on historical loss experience as well as changes in the composition of our pass-rated loan portfolio.
The allowance for credit losses, which includes a liability for losses on unfunded commitments, totaled $172.7$191.3 million at March 31,September 30, 2016, $150.1 million at December 31, 2015 and $115.9$138.1 million at March 31,September 30, 2015. The combined allowance percentage increased to 1.43%1.51% at March 31,September 30, 2016 from 1.28% and 1.08%1.19% at December 31, 2015 and March 31,September 30, 2015, respectively. The combined allowance as a percent of loans held for investment, excluding mortgage finance loans, has trended up during 2015 and into 2016 primarily as a result of the increasing provision for credit losses driven by deterioration in our energy portfolio and management's allocation of a higher reserve to the Bank's pass-rated portfolio as deemed appropriate in light of current environmental conditions.
The overall allowance for loan losses results from consistent application of our loan loss reserve methodology. At March 31,September 30, 2016, we believe the allowance is sufficientappropriate to cover all inherent losses in the portfolio and has been derived from consistent application of our methodology. Should any of the factors considered by management in evaluating the

adequacy of the reserveallowance for loan losses change, our estimate of inherent losses in the portfolio could also change, which would affect the level of future provisions for loan losses.

(1)As of March 31,September 30, 2016, December 31, 2015 and March 31,September 30, 2015, non-accrual loans included $37.9$19.7 million, $24.9 million and $12.7$26.1 million, respectively, in loans that met the criteria for restructured.
(2)We did not have a valuation allowance recorded against the OREO balance at March 31,September 30, 2016, December 31, 2015 or March 31,September 30, 2015.
Total non-performing assets at March 31,September 30, 2016 increased $121.8$78.3 million from March 31,September 30, 2015 and $10.4$7.8 million from December 31, 2015. We experienced a significant increase in levels of non-performing assets during the threenine months ended March 31,September 30, 2016 compared to the same period in 2015, primarily related to deterioration in our energy portfolio.portfolio, which was expected as energy prices remain low. Energy non-performing assets totaled $141.3$150.0 million at March 31,September 30, 2016 compared to $322,000

$36.9 million at March 31,September 30, 2015 and $120.4 million at December 31, 2015. The increase is primarily related to energy loans, which was expected as energy prices remain low. Our

provision for credit losses increased as a result of changes in the applied risk weights, an increase in total criticized loans, primarily related to the energy portfolio, and continuing growth in loans held for investment, excluding mortgage finance loans. Risk weights are based on historical loss experience as adjusted for current environmental factors as well as changes in the composition of our pass-rated loan portfolio. This resulted in an increase in the allowance for loan losses as a percent of loans excluding mortgage finance loans for March 31,September 30, 2016 compared to December 31, 2015 and March 31,September 30, 2015.
Generally, we place loans held for investment 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. Interest income is subsequently recognized on a cash basis as long as the remaining unpaid principal amount of the loan is deemed to be fully collectible. If collectability is questionable, then cash payments are applied to principal. As of March 31,September 30, 2016, $824,000816,000 of our non-accrual loans were earning on a cash basis. 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.
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 March 31,September 30, 2016, we had $1.7$26.3 million in loans of this type, compared to none at December 31, 2015, which were not included in either non-accrual or 90 days past due categories.

When foreclosure occurs, the acquired asset is recorded at fair value less selling costs, generally based on appraised value, which may result in partial charge-off of the loan. So long as the property is retained, further reductions in appraised value will result in valuation adjustments being taken as non-interest expense. If the decline in value is believed to be permanent and not just driven by short-term market conditions, a direct write-down of the OREO balance may be taken. We generally pursue sales of OREO when conditions warrant, but we may choose to hold certain properties for a longer term, which can result in additional exposure to decreases in the appraised value of the asset and the incurrence of carrying costs during that holding period. We did not record a valuation expense during the threenine months ended March 31,September 30, 2016 and 2015.
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 GSEs such as Fannie Mae, Freddie Mac or Ginnie Mae. We have elected to carry these loans at fair value based on sales commitments and market quotes. Changes in the fair value of the loans held for sale are included in other non-interest income.
Residential mortgage loans are subject to both credit and interest rate risk. Credit risk is managed through underwriting policies and procedures, including collateral requirements, which are generally accepted by the secondary loan markets. Exposure to interest rate fluctuations is partially managed through forward sales contracts, which set the price for loans that will be delivered in the next 60 to 90 days.
The table below presents the unpaid principal balance of loans held for sale and related fair values at March 31,September 30, 2016 and December 31, 2015 (in thousands):

No loans held for sale were 90 days or more past due or on non-accrual as of September 30, 2016 and December 31, 2015.
The differences between the fair value carrying amount and the aggregate unpaid principal balance include changes in fair value recorded at and subsequent to funding, gains and losses on the related loan commitment prior to funding and premiums or discounts on acquired loans.

We generally retain the right to service the loans sold, creating MSR assets on our balance sheet. A summary of MSR activities for the threenine months ended March 31,September 30, 2016 is as follows (in thousands):

At MarchSeptember 30, 2016 and December 31, 2016,2015, our servicing portfolio of residential mortgage loans sold included 1,3914,954 and 168 loans, respectively, with an outstandingoutstanding principal balance of $355.2 million.$1.3 billion and $39.0 million, respectively. In connection with the servicing of these loans, we maintain escrow funds for taxes and insuranceinsurance in the name of investors, as well as collections in transit to investors. These escrow funds are segregated and held in separate non-interest-bearing bank accounts at the Bank. These deposits, included in total non-interest-bearing deposits on the consolidated balance sheets, were $2.9$18.5 million at MarchSeptember 30, 2016.
As of September 30, 2016 and December 31, 2016.
For loans securitized and sold during the three months ended March 31, 2016 with servicing rights retained,2015, management used the following assumptions to determine the fair value of MSRs at the date of securitization:MSRs:

In conjunction with the sale and securitization of loans held for sale, we may be exposed to liability resulting from recourse agreements and repurchase agreements. If it is determined subsequent to our sale of a loan that the loan sold is in breach of the representations or warranties made in the applicable sale agreement, we may have an obligation to (a) repurchase the loan for the unpaid principal balance, accrued interest and related advances, (b) indemnify the purchaser against any loss it suffers or (c) make the purchaser whole for the economic benefits of the loan. During the threenine months ended March 31,September 30, 2016, we originated or purchased and sold approximately $342.6 million$1.4 billion of mortgage loans to GSEs.loans.
Our repurchase, indemnification and make whole obligations vary based upon the terms of the applicable agreements, the nature of the asserted breach and the status of the mortgage loan at the time a claim is made. We establish reserves for estimated losses of this nature inherent in the origination of mortgage loans by estimating the probable losses inherent in the population of all loans sold based on trends in claims and actual loss severities experienced. The reserve will include accruals for probable contingent losses in addition to those identified in the pipeline of claims received. The estimation process is designed to include amounts based on any actual losses experienced from actual repurchase activity.
Because the MCA business commenced in 2015, we have no historical data to support the establishment of a reserve. The baseline for the repurchase reserve uses historical loss factors obtained from industry data that are applied to loan pools originated and sold during the threenine months ended March 31,September 30, 2016. The historical industry data loss factors and experienced losses will be accumulated for each sale vintage (year loan was sold) and applied to more recent sale vintages to estimate inherent losses not yet realized. Our estimated exposure related to these loans was $178,000$621,000 at March 31,September 30, 2016 and is recorded in other liabilities in the consolidated balance sheets.sheet. We had no losses due to repurchase, indemnification or make-whole obligations during the year ended March 31, 2016.September 30, 2016 as it relates to our MCA program.

Liquidity and Capital Resources
In general terms, liquidity is a measurement of our ability to meet our cash needs. Our objective in managing our liquidity is to maintain our ability to meet loan commitments, purchase 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 Balance Sheet Management Committee (“BSMC”), which take into account the demonstrated marketability of 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, 2015 and for the threenine months ended March 31,September 30, 2016 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 Federal Home Loan Bank ("FHLB") borrowings, which are generally used to fund mortgage finance assets.
Deposit growth and increases in borrowing capacity related to our mortgage finance loans have resulted in an increase in liquidity assets to $2.6$3.5 billion at March 31,September 30, 2016. The following table summarizes the growth in and composition of liquidity assets (in thousands):

Our liquidity needs forto support of 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 relationships with customers, 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.

We also have access to incremental deposits through brokered retail certificates of deposit, or CDs. These traditional brokered deposits are generally of short maturities, 30 to 90 days, and are used to fund temporary differences in the growth in loans balances, including growth in loans held for sale or other specific categories of loans as compared to customer deposits.

We have access to sources of traditional brokered deposits that we estimate to be $3.5 billion. Based on our internal guidelines, we have chosen to limit our use of these sources to a lesser amount. Customer deposits (total deposits, including relationship brokered deposits, minus brokered CDs) at March 31,September 30, 2016 increased by $1.2$3.1 billion from December 31, 2015 and increased $2.2$3.0 billion from March 31,September 30, 2015.
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 assets, 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, treasury, tax and loan notes and advances from the FHLB and the Federal Reserve.

At March 31,September 30, 2016, we had a revolving, non-amortizing line of credit with a maximum availability of $130.0 million. This line of credit matures on December 21, 2016. The loan proceeds may be used for general corporate purposes including funding regulatory capital infusions into the Bank. The loan agreement contains customary financial covenants and restrictions. As of March 31,September 30, 2016, $4.0$20.0 million in borrowings were outstanding compared to none at December 31, 2015.
Our equity capital, including $150 million in preferred stock, averaged $1.6$1.7 billion for the threenine months ended March 31,September 30, 2016, as compared to $1.5 billion for the same period in 2015. 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.
As of March 31,September 30, 2016, our capital ratios were above the levels required to be well capitalized. We believe that our earnings, periodic capital raising transactions and the addition of loan and deposit relationships will allow us to continue to grow organically.

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 principlesGAAP and generally accepted inpractice within the United States.banking industry. The more significant of these policies are summarized in Note 1 - Operations and Summary of Significant Accounting Policies in the accompanying notes to the consolidated financial statements. Not all significant accounting policies require management to make difficult, subjective or complex judgments. However, the policypolicies noted below could be deemed to meet the SEC’s definition of a critical accounting policy.
Allowance for Loan Losses
Management considers the policies related to the allowance for loan losses as the most critical to the financial statement presentation. The total allowance for loan losses includes activity related to allowances calculated in accordance with ASC 310, Receivables, and ASC 450, Contingencies. The allowance for loan losses is established through a provision for loancredit losses charged to current earnings. The amount maintained in the allowance reflects management’s continuing evaluation of the loan losses inherent in the loan portfolio. The allowance for loan losses is comprised of specific reserves assigned to certain classified loans and general reserves. Factors contributing to the determination of specific reserves include the creditworthiness of the borrower, and more specifically, changes in the expected future receipt of principal and interest payments and/or in the value of pledged collateral. A reserve is recorded when the carrying amount of the loan exceeds the discounted estimated cash flows using the loan’s initial effective interest rate or the fair value of the collateral for certain collateral dependent loans. For purposes of determining the general reserve,allowance, the portfolio is segregated by product types in order to recognize differing risk profiles among categories, and then further segregated by credit grades. See “Summary of Loan Loss Experience” and Note 4 – Loans Held for Investment and Allowance for Loan Losses 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 loan losses.


ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES 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. Petroleum and natural gas commodity prices declined substantially during 2014 and 2015, and prices have continued to be suppressed through 2016. Such declines in commodity prices, have and, if continued, could negatively impact our energy clients' ability to perform on their loan obligations. Management does not currently expect the current decline in commodity prices to have a material adverse effect on our financial position. Foreign exchange rates, commodity prices and/or equity prices do not pose significant market risk to us.
The responsibility for managing market risk rests with the BSMC, which operates under policy guidelines established by our board of directors. The negative acceptable variation in net interest revenue due to a 200 basis point increase or decrease in interest rates is generally limited by these guidelines to +/- 5%. These guidelines also establish maximum levels for short-term borrowings, short-term assets and public and brokered deposits. They also establish minimum levels for unpledged assets, among other things. Oversight of our compliance with these guidelines is the ongoing responsibility of the BSMC, with exceptions reported to our board of directors 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 March 31,September 30, 2016, 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 and changes in composition of funding.

The table above sets forth the balances as of March 31,September 30, 2016 for interest bearinginterest-bearing assets, interest bearinginterest-bearing liabilities, and the total of non-interest bearingnon-interest-bearing deposits and stockholders’ equity. 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 and loan and deposit account balances over the next twelve months based on three interest rate scenarios. These are a “most likely” rate scenario and two “shock test” scenarios.
The “most likely” rate scenario is based on the consensus forecast of future interest rates published by independent sources. These forecasts incorporate future spot rates and relevant spreads of instruments that are actively traded in the open market. The Federal Reserve’s Federal funds target affects short-term borrowing rates; the prime lending rate and LIBOR are the basis for most of our variable-rate loan pricing. The 10-year mortgage rate is also monitored because of its effect on prepayment speeds for mortgage-backed securities. We believe these are our primary interest rate exposures. We are not currently using derivatives to manage our interest rate exposure.
The two “shock test” scenarios assume a sustained parallel 100 and 200 basis point increase in interest rates. As short-term rates have remained low through 2015 and the first threenine months of 2016, we do not believe that analysis of an assumed decrease in

interest rates would provide meaningful results. 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.

Our interest rate risk exposure model incorporates assumptions regarding the level of interest rate or balance changes on indeterminable maturity deposits (demand deposits, interest-bearing transaction accounts and savings accounts) for a given level of market rate changes. These assumptions have been developed through a combination of historical analysis and future expected pricing behavior. Changes in prepayment behavior of mortgage-backed securities and 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 planned growth and new business activities is factored into the simulation model. This modeling indicated interest rate sensitivity as follows (in thousands):
 
 Anticipated Impact Over the Next Twelve Months as Compared to Most Likely Scenario Anticipated Impact Over the Next Twelve Months as Compared to Most Likely Scenario
 100 bp Increase 200 bp Increase 100 bp Increase 200 bp Increase
 March 31, 2016 March 31, 2015
Change in net interest income$103,009
 $212,583
 $79,855
 $169,010
 Anticipated Impact Over the Next Twelve Months as Compared to Most Likely Scenario Anticipated Impact Over the Next Twelve Months as Compared to Most Likely Scenario
 100 bp Increase 200 bp Increase 100 bp Increase 200 bp Increase
 September 30, 2016 September 30, 2015
Change in net interest income$117,094
 $241,366
 $86,998
 $182,672
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 may differ from simulated results due to timing, magnitude and frequency of interest rate changes as well as changes in market conditions and management strategies, among other factors.
