1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES
Nature of Operations-Allegiance Bancshares, Inc. (“Allegiance”) and its wholly-owned subsidiary, Allegiance Bank, (the “Bank”, and together with Allegiance, collectively referred to as the “Company”) provide commercial and retail loans and commercial banking services. The Company derives substantially all of its revenues and income from the operation of the Bank. The Company is focused on delivering a wide variety of relationship-driven commercial banking products and community-oriented services tailored to meet the needs of small to mid-sized businesses, professionals and individuals through its 16 offices and one loan production office in Houston, Texas and the surrounding region. The Bank provides its customers with a variety of banking services including checking accounts, savings accounts and certificates of deposit, and its primary lending products are commercial, personal, automobile, mortgage and home improvement loans. The Bank also offers safe deposit boxes, automated teller machines, drive-through services and 24-hour depository facilities.
Basis of Presentation-The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and in accordance with guidance provided by the Securities and Exchange Commission. Accordingly, the condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments considered necessary for a fair presentation of the financial position, results of operations and cash flows of the Company on a consolidated basis, and all such adjustments are of a normal recurring nature. Transactions with Allegiance have been eliminated. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.
Significant Accounting and Reporting Policies
The Company’s significant accounting and reporting policies can be found in Note 1 of the Company’s annual financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016.
New Accounting Standards
Newly Issued But Not Yet Effective Accounting Standards
ASU 2014-09 “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 supersedes the revenue recognition requirements in Revenue Recognition (Topic 605), and most industry-specific guidance throughout the Industry Topics of the Codification. 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 is effective for the Company beginning on January 1, 2018, with retrospective application to each prior reporting period presented. The Company expects to adopt ASU 2014-09 in the first quarter 2018 using the modified retrospective approach, which includes presenting the cumulative effect of initial application along with supplementary disclosures. The Company is evaluating the full effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures; however, adoption of the ASU is not expected to have a significant impact. The Company’s primary sources of revenues are derived from interest and dividends earned on loans, investment securities and other financial instruments that are not within the scope of ASU 2014-09.
ASU 2016-02 “Leases (Topic 842)." ASU 2016-02 will, among other things, require lessees to recognize a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, “Revenue from
8
ALLEGIANCE BANCSHARES, INC.CONDENSED NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTSSEPTEMBER 30, 2017(Unaudited)
Contracts with Customers.” ASU 2016-02 will be effective for the Company on January 1, 2019 and will require transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early application of this ASU is permitted for all entities. Adoption of ASU 2016-02 is not expected to have a material impact on the Company’s financial statements. The Company leases certain properties and equipment under operating leases that will result in the recognition of lease assets and lease liabilities on the Company’s balance sheet under the ASU.
ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” Among other things, ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better form their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, ASU 2016-13 amends the accounting for credit losses on available for sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 is effective for the Company on January 1, 2020 and must be applied using the modified retrospective approach with limited exceptions. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company is currently assessing the impact that the adoption of this standard will have on the financial condition and results of operations of the Company. The Company has formed a team that is assessing its data and system needs and is evaluating the impact of adoption. The Company expects to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, but has not yet determined the magnitude of any such one-time adjustment or the overall impact on the Company’s financial statements.
ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” ASU 2017-04 intends to simplify goodwill impairment testing by eliminating the second step of the analysis under which the implied fair value of goodwill is determined as if the reporting unit were being acquired in a business combination. The update instead requires entities to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for any amount by which the carrying amount exceeds the reporting unit’s fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit. ASU 2017-04 must be applied prospectively and is effective for the Company on January 1, 2020. Early adoption is permitted. The Company does not expect the new guidance to have a material impact on its financial condition or results of operation.
ASU 2017-08 “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities.” ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium to require such premiums to be amortized to the earliest call date unless applicable guidance related to certain pools of securities is applied to consider estimated prepayments. Under prior guidance, entities were generally required to amortize premiums on individual, non-pooled callable debt securities as a yield adjustment over the contractual life of the security. ASU 2017-08 does not change the accounting for callable debt securities held at a discount. ASU 2017-08 will be effective for the Company on January 1, 2019, with early adoption permitted. The Company is currently evaluating the potential impact of ASU 2017-08 on its financial statements.
2. ACQUISITIONS
Acquisition of F&M Bancshares - On January 1, 2015, the Company completed the acquisition of F&M Bancshares, Inc. (“F&M Bancshares”) and its wholly-owned subsidiary Enterprise Bank (“Enterprise”) headquartered in Houston, Texas. Enterprise operated nine bank offices, seven in Houston, Texas and two in Central Texas. During the first quarter of 2016, the Bank completed the sale of the two Central Texas branch locations of Enterprise. The Bank sold $18.2 million and $26.6 million of loans and deposits, respectively, and recorded a gain of approximately $2.1 million on the sale of these branches.

3. GOODWILL AND CORE DEPOSIT INTANGIBLE ASSETS
Changes in the carrying amount of the Company’s goodwill and core deposit intangible assets were as follows:
| Goodwill | Core DepositIntangibles |
| (Dollars in thousands) |
| Balance as of January 1, 2016 | $ | 39,389 | $ | 5,230 |
| Sale of branch assets | — | (390 | ) |
| Amortization | — | (785 | ) |

| Amortization | — | (586 | ) |
| Balance as of September 30, 2017 | $ | 39,389 | $ | 3,469 |

Goodwill is recorded on the acquisition date of an entity. Management performs an evaluation annually, and more frequently if a triggering event occurs, of whether any impairment of the goodwill and other intangible assets has occurred. If any such impairment is determined, a write-down is recorded. As of September 30, 2017, there were no impairments recorded on goodwill and other intangible assets. During the first quarter 2016, the Bank completed the sale of the two Central Texas branch locations of Enterprise and wrote-down the core deposit intangible assets related to those locations.
The estimated aggregate future amortization expense for core deposit intangible assets remaining as of September 30, 2017 is as follows (dollars in thousands):
| Remaining 2017 | $ | 195 |
| 2018 | 781 |
| 2019 | 781 |

| Total | $ | 321,151 | $ | 1,564 | $ | (6,260 | ) | $ | 316,455 |

As of September 30, 2017, the Company’s management does not expect to sell any securities classified as available for sale with material unrealized losses, and the Company believes it is more likely than not it will not be required to sell any of these securities before their anticipated recovery, at which time the Company will receive full value for the securities. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline.

Credit Quality Indicators
The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including factors such as: current financial information, historical payment experience, credit documentation, public information and current economic trends. The Company analyzes loans individually by classifying the loans by credit risk. As part of the ongoing monitoring of the credit quality of the Company’s loan portfolio and methodology for calculating the allowance for credit losses, management assigns and tracks risk ratings to be used as credit quality indicators.
The following is a general description of the risk ratings used:
Pass—Loans classified as pass are loans with low to average risk and not otherwise classified as watch, special mention, substandard or doubtful. In addition, the guaranteed portion of SBA loans are considered pass risk rated loans.
16
ALLEGIANCE BANCSHARES, INC.CONDENSED NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTSSEPTEMBER 30, 2017(Unaudited)
Watch—Loans classified as watch loans may still be of high quality, but have an element of risk added to the credit such as declining payment history, deteriorating financial position of the borrower or a decrease in collateral value.
Special Mention—Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.
Substandard—Loans classified as substandard have well-defined weaknesses on a continuing basis and are inadequately protected by the current net worth and paying capacity of the borrower, impaired or declining collateral values, or a continuing downturn in their industry which is reducing their profits to below zero and having a significantly negative impact on their cash flow. These classified loans are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.
Doubtful—Loans classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions and values highly questionable and improbable.
Based on the most recent analysis performed, the risk category of loans by class of loan at September 30, 2017 is as follows:

Troubled debt restructurings resulted in charge-offs of $407 thousand during the nine months ended September 30, 2017. There were no charge offs from troubled debt restructurings during the three months ended September 30, 2017. There were $442 thousand in charge-offs resulting from troubled debt restructurings during the nine months ended September 30, 2016. There were no charge offs from troubled debt restructurings during the three months ended September 30, 2016.
As of September 30, 2017, a $12 thousand loan was modified under a troubled debt restructuring during the previous twelve month period that subsequently defaulted and was charged off during the nine months ended September 30, 2017. As of September 30, 2016, a $32 thousand loan was modified under troubled debt restructurings during the previous twelve month period that subsequently defaulted during the nine months ended September 30, 2016. The modifications primarily related to extending the amortization periods of the loans. Default is determined at 90 or more days past due. The Company did not grant principal reductions on any restructured loans.
6. FAIR VALUE
The Company uses fair value measurements to record fair value adjustments to certain assets and to determine fair value disclosures. Fair value represents the exchange price that would be received from selling an asset or paid to transfer a liability, otherwise known as an “exit price,” in the principal or most advantageous market available to the entity in an orderly transaction between market participants on the measurement date.
Fair Value Hierarchy
The Company groups financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
| • | Level 1—Quoted prices for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. |

22
ALLEGIANCE BANCSHARES, INC.CONDENSED NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTSSEPTEMBER 30, 2017(Unaudited)
| • | Level 2—Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. |

| • | Level 3—Significant unobservable inputs that reflect management’s judgment and assumptions that market participants would use in pricing an asset or liability that are supported by little or no market activity. |

Impaired Loans with Specific Allocation of Allowance
During the nine months ended September 30, 2017 and the year ended December 31, 2016, certain impaired loans were reevaluated and reported at fair value through a specific allocation of the allowance for loan losses. At September 30, 2017, the total reported fair value of impaired loans of $13.3 million based on collateral valuations utilizing Level 3 valuation inputs had a carrying value of $17.1 million that was reduced by specific allowance allocations totaling $3.8 million. At December 31, 2016, the total reported fair value of impaired loans of $2.3 million based on collateral valuations utilizing Level 3 valuation inputs had a carrying value of $3.9 million that was reduced by specific allowance allocations totaling $1.7 million.
Other Real Estate Owned
At September 30, 2017, the balance of other real estate owned included $453 thousand of foreclosed commercial real estate properties recorded as a result of obtaining physical possession of the property. At September 30, 2017, there was no formal foreclosure in process on this other real estate owned. The Company had $1.5 million of other real estate owned at December 31, 2016.
7. DEPOSITS
Time deposits that meet or exceed the Federal Deposit Insurance Corporation Insurance limit of $250 thousand at September 30, 2017 and December 31, 2016 were $214.9 million and $196.5 million, respectively.
Scheduled maturities of time deposits for the next five years are as follows (dollars in thousands):
| Within one year | $ | 483,649 |
| After one but within two years | 161,360 |
| After two but within three years | 38,039 |
| After three but within four years | 28,941 |
| After four but within five years | 44,895 |
| Total | $ | 756,884 |

The Company has $230.1 million and $65.9 million of brokered deposits as of September 30, 2017 and December 31, 2016, respectively; and there are no major concentrations of deposits with any one depositor at September 30, 2017 and December 31, 2016. Included in these amounts are reciprocal deposits of $163.4 million and $64.8 million, at September 30, 2017 and December 31, 2016, respectively.
8. BORROWINGS AND BORROWING CAPACITY
The Company has an available line of credit with the Federal Home Loan Bank (“FHLB”) of Dallas, which allows the Company to borrow on a collateralized basis. FHLB advances are used to manage liquidity as needed. The advances are secured by a blanket lien on certain loans. Maturing advances are replaced by drawing on available cash, making additional borrowings or through increased customer deposits. At September 30, 2017, the Company had a total borrowing capacity of $886.6 million, of which $646.0 million was available and $240.6 million was outstanding. FHLB advances of $207.0 million were outstanding at September 30, 2017, at a weighted average interest rate of 1.32%. Letters of credit were $33.6 million at September 30, 2017, of which $25.0 million expired in October 2017 and was renewed until October 2018, $3.1 million will expire in February 2018 and $5.5 million will expire in August 2018.
In 2015, the Company borrowed an additional $18.0 million under its credit agreement with another financial institution, which was in addition to the $10.1 million of indebtedness incurred under the same credit agreement in 2014. The credit agreement matures in December 2021. The Company used the funds borrowed in 2015 to repay debt that F&M Bancshares owed and used the funds borrowed in 2014 to pay off a previous borrowing with another financial institution that had been entered into during 2013 in conjunction with the acquisition of Independence Bank. In October 2015, the Company paid down $27.5 million of the credit agreement with a portion of the proceeds from the initial public offering of Allegiance common stock. The credit agreement includes certain restrictive covenants. At September 30, 2017, the Company was in
25
ALLEGIANCE BANCSHARES, INC.CONDENSED NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTSSEPTEMBER 30, 2017(Unaudited)
compliance with all such debt covenants, except that return on assets at the Bank was 0.47% (below the required minimum), primarily due to the unusually large provision for loan losses experienced during the quarter. Such non-compliance has been waived by the lender with respect to the quarter ended September 30, 2017. The interest rate on the outstanding debt under the revolving credit agreement is the Prime rate minus 25 basis points, or 4.00%, at September 30, 2017, and is paid quarterly. Scheduled principal maturities are as follows (dollars in thousands):

9. SUBORDINATED DEBENTURES
On January 1, 2015, the Company acquired F&M Bancshares and assumed Farmers & Merchants Capital Trust II and Farmers & Merchants Capital Trust III. Each of these trusts is a capital or statutory business trust organized for the sole purpose of issuing trust securities and investing the proceeds in the Company’s junior subordinated debentures. The preferred trust securities of each trust represent preferred beneficial interests in the assets of the respective trusts and are subject to mandatory redemption upon payment of the junior subordinated debentures held by the trust. The common securities of each trust are wholly owned by the Company. Each trust’s ability to pay amounts due on the trust preferred securities is solely dependent upon the Company making payment on the related junior subordinated debentures. The debentures, which are the only assets of each trust, are subordinate and junior in right of payment to all of the Company’s present and future senior indebtedness. The Company has fully and unconditionally guaranteed each trust’s obligations under the trust securities issued by such trust to the extent not paid or made by such trust, provided such trust has funds available for such obligations.
Under the provisions of each issue of the debentures, the Company has the right to defer payment of interest on the debentures at any time, or from time to time, for periods not exceeding five years. If interest payments on either issue of the debentures are deferred, the distributions on the applicable trust preferred securities and common securities will also be deferred.
The Company assumed the junior subordinated debentures with an aggregate original principal amount of $11.3 million and a carrying fair value at September 30, 2017 of $9.3 million. At acquisition, the Company recorded a discount of $2.5 million on the debentures. The difference between the carrying value and contractual balance will be recognized as a yield adjustment over the remaining term for the debentures. At September 30, 2017, the Company had $11.3 million outstanding in junior subordinated debentures issued to the Company’s unconsolidated subsidiary trusts. The junior subordinated debentures are included in Tier 1 capital under current regulatory guidelines and interpretations.

10. INCOME TAXES
The amount of the Company’s federal and state income tax expense is influenced by the amount of pre-tax income, the amount of tax-exempt income and the amount of other nondeductible items. For the three and nine months ended September 30, 2017, income tax expense was $887 thousand and $4.1 million, respectively, compared with $2.1 million and $7.5 million, respectively, for the three and nine months ended September 30, 2016. The effective income tax rate for the three and nine months ended September 30, 2017 was 22.9% and 22.3%, respectively, compared to 27.8% and 30.6%, respectively, for the three and nine months ended September 30, 2016. The decrease in income tax expense and the effective tax rate year over year was primarily attributable to the excess tax benefit from the exercise of stock options by employees, which was recognized in income tax expense as a result of the adoption of ASU 2016-09. Additionally, the decrease in income tax expense and the effective tax rate was due to the increase in tax free income from the purchase of additional municipal securities from the prior year. During the nine months ended September 30, 2017, the impact on the tax rate due to the excess tax benefit on stock options exercised and the increased tax free income from the purchase of municipal securities was 5.3% and 9.0%, respectively.
Interest and penalties related to tax positions are recognized in the period in which they begin accruing or when the entity claims the position that does not meet the minimum statutory thresholds. The Company does not have any uncertain tax positions and does not have any interest and penalties recorded in the income statement for the three and nine months ended September 30, 2017 and 2016. The Company is no longer subject to examination by the U.S. Federal Tax Jurisdiction for the years prior to 2013.
11. STOCK BASED COMPENSATION
During 2015, the Company’s Board of Directors and shareholders approved the 2015 Amended and Restated Stock Awards and Incentive Plan (the “Plan”) covering certain awards of stock-based compensation to key employees and directors of the Company. The Plan was amended in 2017 as the shareholders authorized a maximum aggregate number of shares of stock to be issued of 1,900,000, any or all of which may be issued through incentive stock options. The Company accounts for stock based employee compensation plans using the fair value-based method of accounting. The Company recognized total stock based compensation expense of $497 thousand and $1.3 million for the three and nine months ended September 30, 2017, respectively, and $370 thousand and $1.1 million for the three and nine months ended September 30, 2016, respectively.
Stock Options
Options to purchase a total of 1,290,431 shares of Company stock have been granted as of September 30, 2017. Under the Plan, options are exercisable up to 10 years from the date of the grant and are fully vested 4 years after the date of grant.The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model.

Restricted Stock Awards
During the nine months ended 2017, the Company issued 28,106 shares of restricted stock. The forfeiture restrictions on restricted stock shares will lapse over a period of 4 years, and the shares are considered outstanding at the date of issuance. The Company accounts for restricted stock grants by recording the fair value of the grant on the award date as compensation expense over the vesting period.

12. OFF-BALANCE SHEET ARRANGEMENTS, COMMITMENTS AND CONTINGENCIES
In the normal course of business, the Company enters into various transactions, which, in accordance with accounting principles generally accepted in the United States, are not included in the Company’s consolidated balance sheets. The Company enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and standby letters of credit, which involve to varying degrees elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company uses the same credit policies in making commitments and conditional obligations as it does for on balance sheet instruments.

| Total | $ | 395,881 | $ | 259,534 | $ | 363,245 | $ | 232,675 |

Commitments to make loans are generally made for an approval period of 120 days or fewer. As of September 30, 2017, the funded fixed rate loan commitments had interest rates ranging from 1.60% to 7.50% with a weighted average maturity and rate of 2.76 years and 5.03%, respectively.
Litigation
From time to time, the Company is subject to claims and litigation arising in the ordinary course of business. In the opinion of management, the Company is not party to any legal proceedings the resolution of which it believes would have a material adverse effect on the Company’s business, prospects, financial condition, liquidity, results of operation, cash flows or capital levels. However, one or more unfavorable outcomes in any claim or litigation against the Company could have a material adverse effect for the period in which such claim or litigation is resolved. In addition, regardless of their merits or their ultimate outcomes, such matters are costly, divert management’s attention and may materially adversely affect the Company’s reputation, even if resolved in its favor. The Company intends to defend itself vigorously against any future claims or litigation.
13. REGULATORY CAPITAL MATTERS
The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Capital adequacy guidelines, and for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities and certain off balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weightings and other factors. Failure to meet minimum capital requirements can cause regulators to initiate actions that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. The final rules implementing Basel Committee on Banking Supervision's capital guideline for U.S. Banks (Basel III Rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. Starting in January 2016, the implementation of the capital conservation buffer was effective for the Company starting at the 0.625% level and increasing 0.625% each year thereafter, until it reaches 2.5% on January 1, 2019. Management believes as of September 30, 2017 and December 31, 2016 the Company and the Bank met all capital adequacy requirements to which they were then subject.
Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required.

14. EARNINGS PER COMMON SHARE
Diluted earnings per common share is computed using the weighted-average number of common shares determined for the basic earnings per common share computation plus the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock using the treasury stock method. Outstanding stock options issued by the Company represent the only dilutive effect reflected in diluted weighted average shares. Restricted shares are considered outstanding at the date of grant, accounted for as participating securities and included in basic and diluted weighted average common shares outstanding.

Overview
We generate most of our revenues from interest income on loans, service charges on customer accounts and interest income from investments in securities. We incur interest expense on deposits and other borrowed funds and noninterest expenses such as salaries and employee benefits and occupancy expenses. Net interest income is the difference between interest income on earning assets such as loans and securities and interest expense on liabilities such as deposits and borrowings that are used to fund those assets. Net interest income is our largest source of revenue. To evaluate net interest income, we measure and monitor (1) yields on our loans and other interest-earning assets, (2) the interest expenses of our deposits and other funding sources, (3) our net interest spread and (4) our net interest margin. Net interest spread is the difference between rates earned on interest-earning assets and rates paid on interest-bearing liabilities. Net interest margin is calculated as net interest income divided by average interest-earning assets. Because noninterest-bearing sources of funds, such as noninterest-bearing deposits and shareholders’ equity, also fund interest-earning assets, net interest margin includes the benefit of these noninterest-bearing sources.
Our net interest income is affected by changes in the amount and mix of interest-earning assets and interest-bearing liabilities, referred to as a “volume change.” Periodic changes in the volume and types of loans in our loan portfolio are affected by, among other factors, economic and competitive conditions in Texas and specifically in the Houston metropolitan area, as well as developments affecting the real estate, technology, financial services, insurance, transportation, manufacturing and energy sectors within our target market and throughout the state of Texas.
Our net interest income is also affected by changes in yields earned on interest-earning assets and rates paid on interest-bearing deposits and other borrowed funds, referred to as a “rate change.” Fluctuations in market interest rates are driven by many factors, including governmental monetary policies, inflation, deflation, macroeconomic developments, changes in unemployment, the money supply, political and international conditions and conditions in domestic and foreign financial markets.
Our objective is to grow and strengthen our community banking franchise by deploying our super-community banking strategy and pursuing select strategic acquisitions in the Houston metropolitan area. We have positioned ourselves to be a leading provider of personalized commercial banking services by emphasizing the strength and capabilities of local bank office management and by providing superior customer service. We have made the strategic decision to focus on the Houston metropolitan area because of our deep roots and experience operating through a variety of economic cycles in this large and vibrant market.
Super-community banking strategy. Our super-community banking strategy emphasizes local delivery of the excellent customer service associated with community banking combined with the products, efficiencies and scale associated with larger banks. By empowering our personnel to make certain business decisions at a local level in order to respond quickly to customers' needs, we are able to establish and foster strong relationships with customers through superior service. We operate full-service decentralized bank offices and employ lenders with strong underwriting credentials who are authorized to make loan and underwriting decisions up to prescribed limits at the bank office level. We support bank office operations with a centralized credit approval process for larger credit relationships, loan operations, information technology, core data processing, accounting, finance, treasury and treasury management support, deposit operations and executive and board oversight. We emphasize lending to and banking with small to medium-sized businesses, with which we believe we can establish stronger relationships through excellent service and provide lending that can be priced on terms that are more attractive to us than would be achieved by lending to larger businesses. We believe this approach produces a clear competitive advantage by delivering an extraordinary customer experience and fostering a culture dedicated to achieving both superior external and internal service levels.
We plan to continue to emphasize the super-community banking strategy to organically grow our presence in the Houston metropolitan area through:
| • | increasing the productivity of existing bankers, as measured by loans, deposits and fee income per banker, while enhancing profitability by leveraging our existing operating platform; |

33
| • | focusing on local and individualized decision-making, allowing us to provide customers with rapid decisions on loan requests, which we believe allows us to effectively compete with larger financial institutions; |

| • | identifying and hiring additional seasoned bankers in the Houston metropolitan area who will thrive within our super-community banking model, and opening additional branches where we are able to attract seasoned bankers; and |

| • | developing new products designed to serve the increasingly diversified Houston economy, while preserving our strong culture of risk management. |

Select strategic acquisitions. We intend to continue to expand our market position in the Houston metropolitan area through organic growth, including with the establishment of de novo branch locations, and through a disciplined acquisition strategy. We focus on like-minded community banks with similar lending strategies to our own when evaluating acquisition opportunities. We believe that our management’s experience in assessing, executing and integrating target institutions will allow us to capitalize on acquisition opportunities.
Critical Accounting Policies
Our accounting policies are integral to understanding our results of operations. Our accounting policies are described in detail in Note 1 to our Annual Report on Form 10-K for the year ended December 31, 2016. We believe that of our accounting policies, the following may involve a higher degree of judgment and complexity:
Securities
Debt securities are classified as available for sale when they might be sold before maturity. Securities available for sale are carried at fair value. Unrealized gains and losses are excluded from earnings and reported, net of tax, as a separate component of shareholders’ equity until realized. Securities within the available for sale portfolio may be used as part of our asset/liability strategy and may be sold in response to changes in interest rate risk, prepayment risk or other similar economic factors.
Interest earned on these assets is included in interest income. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method.
Management evaluates debt securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement, and (2) OTTI related to other factors, which is recognized in other comprehensive income, net of applicable taxes. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the security.
Nonperforming and Past Due Loans
Loans are placed on nonaccrual status when payment in full of principal or interest is not expected or upon which principal or interest has been in default for a period of 90 days or more unless the asset is both well secured and in the process of collection. If the decision is made to continue accruing interest on the loan, periodic reviews are made to confirm the accruing status of the loan. Nonaccrual loans and loans past due 90 days include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans.
When available information confirms that specific loans, or portions thereof, are uncollectible, these amounts are charged off against the allowance. All loan types are considered delinquent after 30 days past due and are typically charged off or charged down no later than 120 days past due, with consideration of, but not limited to, the following criteria in determining the need and optional timing of the charge-off or charge-down: (1) the Bank is in the process of repossession or foreclosure and there appears to be a likely deficiency, (2) the collateral securing the loan has been sold and there is an actual deficiency, (3) the Bank is proceeding with lengthy legal action to collect its balance, (4) the borrower is unable to be located or (5) the borrower
34
has filed bankruptcy. Events requiring charge-offs occur when a shortfall is identified between the recorded investment in the loan and the underlying value of the collateral.
Allowance for Loan Losses
The allowance for loan losses is a valuation allowance that is established through charges to income in the form of a provision for loan losses. The amount of the allowance for loan losses is affected by the following: (1) charge-offs of loans that decrease the allowance, (2) subsequent recoveries on loans previously charged off that increase the allowance and (3) provisions for loan losses charged to income that increase the allowance.
Throughout the year, management estimates the probable incurred losses in the loan portfolio to determine if the allowance for loan losses is adequate to absorb such losses. The allowance for loan losses consists of specific and general components. The specific component relates to loans that are individually classified as impaired. We follow a loan review program to evaluate the credit risk in the loan portfolio. Loans that have been identified as impaired are reviewed on a quarterly basis in order to determine whether a specific reserve is required. The general component covers non-impaired loans and is based on industry and our specific historical loan loss experience, volume, growth and composition of the loan portfolio, the evaluation of our loan portfolio through our internal loan review process, general current economic conditions both internal and external to us that may affect the borrower’s ability to pay, value of collateral and other qualitative relevant risk factors. Based on a review of these estimates, we adjust the allowance for loan losses to a level determined by management to be adequate. Estimates of loan losses are inherently subjective as they involve an exercise of judgment.
Our allowance for loan losses, both in dollars and as a percentage of total loans, is impacted by acquisition accounting. As part of acquisition accounting, acquired loans are initially recognized at fair value with no corresponding allowance for loan losses. Initial fair value of the loans includes consideration of expected credit losses.
Loans for which the terms have been modified, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and therefore classified as impaired. Subsequent to identification as a troubled debt restructuring, such loans are then evaluated for impairment on an individual basis whereby we determine the amount of reserve in accordance with the accounting policy for the impaired loans as part of our allowance for loan losses calculation. If a loan is impaired, a specific valuation allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral.
Accounting for Acquired Loans
At the time of an acquisition, we evaluate loans to determine if they are purchase credit impaired loans. Purchased credit impaired loans are those acquired loans with evidence of credit deterioration for which it was probable at acquisition that we would be unable to collect all contractual payments. We make this determination by considering past due and/or nonaccrual status, prior designation of a troubled debt restructuring, or other factors that may suggest we will not be able to collect all contractual payments. Purchased credit impaired loans are initially recorded at fair value with the difference between fair value and estimated future cash flows accreted over the expected cash flow period as income only to the extent we can reasonably estimate the timing and amount of future cash flows. In this case, these loans would be classified as accruing. In the event we are unable to reasonably estimate timing and amount of future cash flows, the loan is classified as non-accrual. An acquired loan previously classified by the seller as a troubled debt restructuring is no longer classified as such at the date of acquisition. Past due status is reported based on contractual payment status.
Our purchase credit impaired loans have generally been de minimis and comprised 0.02% of our loan portfolio at September 30, 2017. Historically, purchased credit impaired loans have been placed on nonaccrual status and reported as such until we were able to reasonably estimate the timing and amount of future expected cash flows. Income associated with purchased credit impaired loans for the three and nine months ended September 30, 2017 and prior periods has been immaterial.
All loans not otherwise classified as purchase credit impaired are recorded at fair value with the discount to contractual value accreted over the life of the loan. When determining the allowance for loan losses on acquired loans, we bifurcate the allowance between legacy loans and acquired loans. Loans remain designated as acquired until the loan is either (i) renewed or (ii) substantially modified whereby modification results in a new loan. When determining the allowance on acquired loans, we estimate principal losses as compared to our recorded investment, with the recorded investment being net of any unaccreted discounts from the acquisition. At September 30, 2017, we had $142.3 million in acquired loans that have not been renewed or substantially modified, which is net of an unaccreted discount of $343 thousand or 0.24%.
35
Goodwill
Goodwill resulting from business combinations is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill is assessed annually for impairment or when events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Goodwill acquired in a purchase business combination that is determined to have an indefinite useful life, is not amortized, but tested for impairment. We perform our annual impairment test on October 1st. Goodwill is the only intangible asset with an indefinite life on our balance sheet.
Recently Issued Accounting Pronouncements
We have evaluated new accounting pronouncements that have recently been issued and have determined that there are no new accounting pronouncements that should be described in this section that will impact the Company’s operations, financial condition or liquidity in future periods. Refer to Note 1 of the Company’s audited consolidated financial statements for a discussion of recent accounting pronouncements that have been adopted by the Company or that will require enhanced disclosures in the Company’s financial statements in future periods.
Results of Operations
Net income was $3.0 million, or $0.22 per diluted share, for the third quarter 2017 compared to $5.5 million, or $0.42 per diluted share, for the third quarter 2016. Annualized returns on average assets and average equity were 0.43% and 3.90%. respectively, compared to 0.90% and 7.77%, respectively, for the the three months ended September 30, 2017 and 2016, respectively.
The efficiency ratio increased to 62.14% for the third quarter 2017 from 60.34% for the third quarter 2016. The efficiency ratio is calculated by dividing total noninterest expense by the sum of net interest income plus noninterest income, excluding net gains and losses on the sale of loans, securities and assets. Additionally, taxes and provision for loan losses are not part of this calculation.
Net income was $14.4 million, or $1.07 per diluted share, for the nine months ended September 30, 2017 compared to $17.1 million, or $1.31 per diluted share, for the nine months ended September 30, 2016. The first quarter 2016 included a $1.3 million after tax gain on the sale of two Central Texas branch locations that were sold in order to focus on the Houston metropolitan area. Annualized returns on average assets and average equity were 0.73% and 6.55%, respectively, for the nine months ended September 30, 2017 compared to 0.99% and 8.40%, respectively, for the nine months ended September 30, 2016.
Net Interest Income
Three months ended September 30, 2017 compared with three months ended September 30, 2016. Net interest income before the provision for loan losses for the three months ended September 30, 2017 was $27.0 million compared with $23.4 million for the three months ended September 30, 2016, an increase of $3.6 million, or 15.3%. The increase in net interest income was primarily due to organic loan growth.
Interest income was $30.9 million for the three months ended September 30, 2017, an increase of $4.6 million, or 17.4%, compared with the three months ended September 30, 2016, primarily due to an increase of $331.4 million, or 15.1%, in average interest-earning assets. Additionally, during the three months ended September 30, 2017 and September 30, 2016, we benefited from acquisition accounting loan discount accretion of $129 thousand and $309 thousand, respectively.
Interest expense was $3.9 million for the three months ended September 30, 2017, an increase of $994 thousand, or 34.2%, compared to the three months ended September 30, 2016. This increase was primarily due to an increase in average interest-bearing liabilities of $143.5 million, or 9.5%, for the three months ended September 30, 2017 compared to the three months ended September 30, 2016 and an increase in the average cost of interest-bearing liabilities to 93 basis points for the three months ended September 30, 2017 compared to 76 basis points for the same period in 2016. This increase in costs was primarily attributable to the increase in the rate paid on Federal Home Loan Bank borrowings for the three months ended September 30, 2017 compared to the three months ended September 30, 2016.
Tax equivalent net interest margin, defined as net interest income adjusted for tax-free income divided by average interest-earning assets, for the three months ended September 30, 2017 was 4.37%, a decrease of 2 basis points compared to 4.39% for the three months ended September 30, 2016. Tax equivalent adjustments to net interest margin are the result of increasing income from tax-free securities by an amount equal to the taxes that would have been paid if the income were fully taxable based on a 35% federal tax rate, thus making tax-exempt yields comparable to taxable asset yields. The impact of net

acquisition accounting adjustments of $102 thousand and $335 thousand on the tax equivalent net interest margin was an increase of 2 basis points and 6 basis points for the three months ended September 30, 2017 and 2016, respectively.

Nine months ended September 30, 2017 compared with nine months ended September 30, 2016. Net interest income before the provision for loan losses for the nine months ended September 30, 2017 was $76.2 million compared with $66.4 million for the nine months ended September 30, 2016, an increase of $9.8 million, or 14.7%. The increase in net interest income was primarily due to organic loan growth and an increase in the securities portfolio.
Interest income was $87.4 million for the nine months ended September 30, 2017, an increase of $13.1 million, or 17.6%, compared with the nine months ended September 30, 2016, primarily due to an increase of $341.8 million, or 16.5%, in average interest-earning assets. Additionally, during the nine months ended September 30, 2017 and September 30, 2016, we benefited from acquisition accounting loan discount accretion of $536 thousand and $1.1 million, respectively.
Interest expense was $11.2 million for the nine months ended September 30, 2017, an increase of $3.3 million, or 42.2%, compared to the nine months ended September 30, 2016. This increase was primarily due to an increase in average interest-bearing liabilities of $291.6 million, or 20.9%, for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016, and an increase in the average cost of interest-bearing liabilities to 89 basis points for the nine months ended September 30, 2017 compared to 75 basis points for the same period in 2016. This increase in cost was primarily attributable to the increase in average Federal Home Loan Bank borrowings for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016.
Tax equivalent net interest margin for the nine months ended September 30, 2017 was 4.34%, a decrease of 5 basis points compared to 4.39% for the nine months ended September 30, 2016. The impact of net acquisition accounting adjustments of $459 thousand and $1.2 million on the tax equivalent net interest margin was an increase of 2 basis points and 8 basis points for the nine months ended September 30, 2017 and September 30, 2016, respectively.

Provision for Loan Losses
Our allowance for loan losses is established through charges to income in the form of the provision in order to bring our allowance for loan losses to a level deemed appropriate by management. The allowance for loan losses at September 30, 2017 and December 31, 2016 was $23.7 million and $17.9 million, respectively, representing 1.08% and 0.95% of total loans as of such dates. Acquired loans are initially recorded at fair value based on a discounted cash flow valuation methodology that considers, among other things, projected default rates, losses given existing defaults, and recovery rates. No carryover of any allowance for loan losses occurs when loans are acquired. We recorded a $6.9 million provision for loan losses for the quarter ended September 30, 2017 and a $2.2 million provision for the quarter ended September 30, 2016. The increase in the provision for the quarter ended September 30, 2017 compared to the same period in 2016 was primarily due to organic loan growth, estimated losses related to Hurricane Harvey and an increase in net charge-offs of $4.1 million primarily due to an energy-related loan relationship charged-off during the quarter.
We recorded an $11.3 million provision for loan losses for the nine months ended September 30, 2017 and a $4.6 million provision for the nine months ended September 30, 2016. The increase in the provision for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016 was primarily due to organic loan growth, an increase in net charge-offs of $5.0 million primarily due to an energy-related loan relationship charged-off, a net increase of $2.7 million of allowance on impaired loans and estimated losses related to Hurricane Harvey. During the third quarter 2017, we increased our allowance in part due to the immediate uncertainty in the Houston economy and estimated losses related to Hurricane Harvey that occurred in August 2017. We performed a thorough assessment of the impact of the Hurricane on our customers as well as the adequacy of the allowance for loan losses on our current portfolio.

Noninterest Income
Our primary sources of noninterest income are service charges on deposit accounts, nonsufficient funds fees, rebates from correspondent banks and debit and ATM card income. Noninterest income does not include loan origination fees, which are recognized over the life of the related loan as an adjustment to yield using the interest method.
Three months ended September 30, 2017 compared with three months ended September 30, 2016. Noninterest income totaled $1.5 million for the three months ended September 30, 2017 compared with $1.3 million for the same period in 2016, an increase of $186 thousand, or 14.6%.
Nine months ended September 30, 2017 compared with nine months ended September 30, 2016. Noninterest income totaled $4.3 million for the nine months ended September 30, 2017 compared with $5.8 million for the same period in 2016, a decrease of $1.5 million, or 26.1%. The nine months ended September 30, 2017 included the $2.1 million gain, $1.3 million after tax, on the sale of the two Central Texas branch locations.

Noninterest Expense
Three months ended September 30, 2017 compared with three months ended September 30, 2016. Noninterest expense was $17.7 million for the three months ended September 30, 2017 compared to $14.9 million for the three months ended September 30, 2016, an increase of $2.8 million, or 18.7%. This increase was primarily due to increased salaries and benefits and professional service fees incurred to support growth initiatives.
Nine months ended September 30, 2017 compared with nine months ended September 30, 2016. Noninterest expense was $50.7 million for the nine months ended September 30, 2017 compared to $43.1 million for the nine months ended September 30, 2016, an increase of $7.6 million, or 17.7%. This increase was primarily due to increases in salaries and benefits as a result of the increased headcount and professional service fees related to supporting growth initiatives.

Salaries and Employee Benefits. Salaries and benefits increased $1.8 million, or 18.4%, for the three months ended September 30, 2017 compared to the same period in 2016 and increased $4.3 million, or 15.3%, for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016. These increases for the three and nine months ended September 30, 2017 over the same periods in 2016 were primarily due to the addition of high quality lenders and key personnel hired to strengthen our infrastructure to support our future growth plans.
Professional Fees. Professional fees increased $380 thousand, or 85.9%, for the three months ended September 30, 2017 compared to the same period in 2016 and increased $1.3 million, or 96.4%, for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016 as we continued to focus on enhancing the operational and regulatory requirements applicable to a larger bank as we pursue our growth strategy.
Efficiency Ratio
The efficiency ratio is a supplemental financial measure utilized in management’s internal evaluation of our performance and is not calculated based on generally accepted accounting principles. A GAAP-based efficiency ratio is calculated by dividing total noninterest expense, excluding credit loss provisions, by net interest income plus total noninterest income, as shown in the Consolidated Statements of Income. We calculate our efficiency ratio by excluding from noninterest income the net gains and losses on the sale of loans, securities and assets (including the sale of the two acquired Central Texas branches), which can vary widely from period to period. Additionally, taxes and provision for loan losses are not included in this calculation. An increase in the efficiency ratio indicates that more resources are being utilized to generate the same volume of income and/or being invested to generate future income, while a decrease would indicate a more efficient allocation of resources. Our efficiency ratio was 62.14% and 62.97% for the three and nine months ended September 30, 2017, respectively, compared to 60.34% and 61.37% for the three and nine months ended September 30, 2016, respectively.
We monitor the efficiency ratio in comparison with changes in our total assets and loans, and we believe that maintaining or reducing the efficiency ratio during periods of growth over the long-term will demonstrate the scalability of our operating platform. The efficiency ratio remained elevated for the three and nine months ended September 30, 2017 as we enhanced our lending team and hired key personnel to strengthen our infrastructure to support the operational and regulatory requirements applicable to a larger bank as we pursue our ambitious growth goals.
42
Income Taxes
The amount of federal and state income tax expense is influenced by the amount of pre-tax income, the amount of tax-exempt income and the amount of other nondeductible expenses. Income tax expense decreased $1.2 million, or 57.8%, to $887 thousand for the three months ended September 30, 2017 compared with $2.1 million for the same period in 2016. For the nine months ended September 30, 2017, income tax expense totaled $4.1 million, a decrease of $3.4 million, or 44.9%, compared with $7.5 million for the same period in 2016. Our effective tax rates were 22.9% and 22.3% for the three and nine months ended September 30, 2017, respectively, and 27.8% and 30.6% for the three and nine months ended September 30, 2016. Our effective tax rates decreased for the three and nine months ended September 30, 2017 compared to the same periods in 2016 primarily due to the increase in tax free income from the purchase of additional municipal securities from the prior year. Additionally, the decrease was also the result of the tax benefit from the exercise of stock options by employees during 2017, which was recognized in income tax expense as a result of the adoption of ASU 2016-09. During the nine months ended September 30, 2017, the increased tax free income from the purchase of municipal securities and the impact on the tax rate due to the tax benefit on stock options exercised was 9.0% and 5.3%, respectively.
Financial Condition
Loan Portfolio
At September 30, 2017, total loans were $2.20 billion, an increase of $309.9 million, or 16.4%, compared with December 31, 2016, primarily due to strong organic growth within our loan portfolio.
Total loans as a percentage of deposits were 96.3% and 101.1% as of September 30, 2017 and December 31, 2016, respectively. Total loans as a percentage of assets were 78.3% and 77.2% as of September 30, 2017 and December 31, 2016, respectively.
Lending activities originate from the efforts of our lenders, with an emphasis on lending to small to medium-sized businesses and companies, professionals and individuals located in the Houston metropolitan area.

The principal categories of our loan portfolio are discussed below:
Commercial and Industrial. We make commercial and industrial loans in our market area that are underwritten on the basis of the borrower’s ability to service the debt from income. Our commercial and industrial loan portfolio increased by $29.3 million, or 7.0%, to $446.0 million as of September 30, 2017 compared to $416.8 million as of December 31, 2016.
Our exposure to oil and gas exploration and production companies is roughly 3.2% of our total loan portfolio as of September 30, 2017. We define these customers as those on whom the prices of oil and gas have a significant operational or financial impact. These loans carry an overall allowance of 4.0% at September 30, 2017. The collateral on these loans includes industrial commercial real estate, working capital assets, machining equipment, drilling equipment, general industrial
43
equipment, vehicles, airplanes, ranch property, insurance policies, notes receivable and a hotel. In addition, these loans are all personally guaranteed by the owners of the borrower.
Mortgage Warehouse. We make loans to unaffiliated mortgage loan originators collateralized by mortgage promissory notes which are segregated in our mortgage warehouse portfolio. These promissory notes originated by our mortgage warehouse customers carry terms and conditions as would be expected in the competitive permanent mortgage market and serve as collateral under a traditional mortgage warehouse arrangement whereby such promissory notes are warehoused under a revolving credit facility to allow for the end investor (or purchaser) of the note to receive a complete loan package and remit funds to the bank. For mortgage promissory notes secured by residential property, the warehouse time is normally 10 to 20 days. For mortgage promissory notes secured by commercial property, the warehouse time is normally 40 to 50 days. The funded balance of the mortgage warehouse portfolio can have significant fluctuation based upon market demand for the product, level of home sales and refinancing activity, market interest rates, and velocity of end investor processing times. Volumes of the portfolio tend to peak at the end of each month. Our mortgage warehouse portfolio increased $16.5 million, or 24.7%, to $83.6 million as of September 30, 2017 compared to $67.0 million as of December 31, 2016.
Commercial Real Estate (Including Multi-Family Residential). We make loans collateralized by owner-occupied, nonowner-occupied and multi-family real estate to finance the purchase or ownership of real estate. As of September 30, 2017 and December 31, 2016, 53.1% and 53.5%, respectively, of our commercial real estate loans were owner-occupied. Our commercial real estate loan portfolio increased $153.2 million, or 17.2%, to $1.05 billion as of September 30, 2017 from $892.0 million as of December 31, 2016, as a result of organic loan growth. Included in our commercial real estate portfolio are multi-family residential loans. Our multi-family loans increased $10.9 million, or 20.6%, to $63.8 million as of September 30, 2017 from $52.9 million as of December 31, 2016. We had 95 multi-family loans with an average loan size of $674 thousand as of September 30, 2017.
Commercial Real Estate Construction and Land Development. We make commercial real estate construction and land development loans to fund commercial construction, land acquisition and real estate development construction. Commercial real estate construction and land development loans increased $66.3 million, or 41.7%, to $225.6 million as of September 30, 2017 compared to $159.2 million as of December 31, 2016 as a result of organic loan growth.
1-4 Family Residential (Including Home Equity). Our residential real estate loans include the origination of 1-4 family residential mortgage loans (including home equity and home improvement loans and home equity lines of credit) collateralized by owner-occupied residential properties located in our market area. Our residential real estate portfolio (including home equity) increased $36.4 million, or 14.7%, to $283.4 million as of September 30, 2017 from $247.0 million as of December 31, 2016. The home equity, home improvement and home equity lines of credit portion of our residential real estate portfolio increased $5.6 million, or 16.3%, to $39.9 million as of September 30, 2017 from $34.3 million as of December 31, 2016.
Residential Construction. We make residential construction loans to home builders and individuals to fund the construction of single-family residences with the understanding that such loans will be repaid from the proceeds of the sale of the homes by builders or with the proceeds of a mortgage loan. These loans are secured by the real property being built and are made based on our assessment of the value of the property on an as-completed basis. Our residential construction loans portfolio increased $7.6 million, or 7.7%, to $106.3 million as of September 30, 2017 from $98.7 million as of December 31, 2016 as a result of organic loan growth.
Consumer and Other. Our consumer and other loan portfolio is made up of loans made to individuals for personal purposes. Our consumer and other loan portfolio increased slightly to $11.4 million as of September 30, 2017 from $11.0 million as of December 31, 2016.
Asset Quality
Nonperforming Assets
We have procedures in place to assist us in maintaining the overall quality of our loan portfolio. We have established underwriting guidelines to be followed by our officers and monitor our delinquency levels for any negative or adverse trends.
We had $13.9 million and $16.7 million in nonperforming loans as of September 30, 2017 and December 31, 2016, respectively.

Potential problem loans are included in the loans that are classified as substandard and consist of accruing, restructured and impaired loans that are performing in accordance with contractual terms but for which management has concerns about the ability of an obligor to continue to comply with repayment terms because of the obligor’s potential operating or financial difficulties. Management monitors these loans closely and reviews their performance on a regular basis. Potential problem loans contain potential weaknesses that could improve, persist or further deteriorate. At September 30, 2017 and December 31, 2016, we had $17.2 million and $5.2 million, respectively, in loans of this type which are not included in any of the nonaccrual or 90 days past due loan categories. At September 30, 2017, potential problem loans consisted of seventeen credit relationships. Of the total outstanding balance at September 30, 2017, 48.7% related to one customer in the hospitality industry, 32.4% related to 9 customers in an energy-related industry, 8.4% related to one customer in the residential and commercial building industry, 3.4% related to one customer in the leasing industry, 2.9% related to one customer in the convenience store industry, 1.6% related to one customer in the construction material industry, 1.5% related to two customers in the freight transportation industry and 1.1% related to one customer in the customer services industry. Weakness in these organizations’ operating performance, financial condition and borrowing base deficits for certain energy-related credits, among other factors, have caused us to heighten the attention given to these credits. As such, all of the loans identified as potential problem loans at September 30, 2017 were graded as substandard accruing loans. Potential problem loans impact the allocation of our allowance for loan losses as a result of the specific reserve assigned to each loan.
Allowance for Credit Losses
The allowance for loan losses is a valuation allowance that is established through charges to earnings in the form of a provision for loan losses. The amount of the allowance for loan losses is affected by the following: (1) charge-offs of loans that decrease the allowance, (2) subsequent recoveries on loans previously charged-off that increase the allowance and (3) provisions for loan losses charged to income that increase the allowance.
All loans acquired from F&M Bancshares were recorded at fair value without a carryover of the F&M Bancshares allowance for loan losses. The discount recognized on acquired loans is prospectively accreted, increasing our basis in such loans. Due to acquisition accounting, our allowance for loan losses to total loans may not be comparable to our peers particularly as it relates to the allowance to gross loan percentage and the allowance to nonperforming loans. Recognizing that acquired purchased credit impaired loans have been de minimis, we monitor credit quality trends on a post-acquisition basis with an emphasis on past due, charge-off, classified loan and nonperforming trends. The amount of discount recorded by the
45
Company on the date of the F&M Bancshares acquisition was $6.0 million, or 1.47%, on loans acquired. The remaining discount on F&M Bancshares acquired loans as of September 30, 2017 was $378 thousand, or 0.34%. The discount on purchased loans considers anticipated credit losses on that portfolio, therefore no allowance for credit losses was established on the acquisition date. The unaccreted discount represents additional protection against potential losses and is presented as a reduction of the recorded investment in the loans rather than an allowance for loan losses. We will continue to look at the portfolio for credit deterioration and establish additional allowances over the remaining discount as needed.
At September 30, 2017, our allowance for loan losses amounted to $23.7 million, or 1.08%, of total loans compared with $17.9 million, or 0.95%, as of December 31, 2016. The increase in the allowance of $5.8 million for the nine months ended September 30, 2017 as compared to the year ended December 31, 2016 was primarily due to an increase in the required reserve associated with organic loan growth, the increase in impaired loans and estimated losses related to Hurricane Harvey. We believe that the allowance for loan losses at September 30, 2017 and December 31, 2016 was adequate to cover probable incurred losses in the loan portfolio as of such dates. The ratio of annualized net charge-offs to average loans outstanding was 0.36% for the nine months ended September 30, 2017 compared to 0.04% for the nine months ended September 30, 2016 and 0.04% for the year ended December 31, 2016.

Available for Sale Securities
We use our securities portfolio to provide a source of liquidity, to provide an appropriate return on funds invested, to manage interest rate risk and to meet pledging and regulatory capital requirements. As of September 30, 2017, the carrying amount of investment securities totaled $323.9 million, an increase of $7.4 million, or 2.3%, compared with $316.5 million as of December 31, 2016. Securities represented 11.5% and 12.9% of total assets as of September 30, 2017 and December 31, 2016, respectively.
All of the securities in our securities portfolio are classified as available for sale. Securities classified as available for sale are measured at fair value in the financial statements with unrealized gains and losses reported, net of tax, as accumulated comprehensive income or loss until realized. Interest earned on securities is included in interest income.

As of September 30, 2017, we did not expect to sell any securities classified as available for sale with material unrealized losses; and management believes that we more likely than not will not be required to sell any securities before their anticipated recovery, at which time we will receive full value for the securities. The unrealized losses are largely due to increases in market interest rates over the yields available at the time the underlying securities were purchased. Management does not believe any of the securities are impaired due to reasons of credit quality. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Accordingly, as of September 30, 2017, management believes any impairment in our securities is temporary, and no impairment loss has been realized in our consolidated statements of income.

The contractual maturity of mortgage-backed securities and collateralized mortgage obligations is not a reliable indicator of their expected life because borrowers may have the right to prepay their obligations. Mortgage-backed securities and collateralized mortgage obligations are typically issued with stated principal amounts and are backed by pools of mortgage loans with varying maturities. The term of the underlying mortgages and loans may vary significantly due to the ability of a borrower to prepay and, in particular, monthly pay downs on mortgage-backed securities tend to cause the average life of the securities to be much different than the stated contractual maturity. During a period of increasing interest rates, fixed rate mortgage-backed securities do not tend to experience heavy prepayments of principal and, consequently, the average life of this security will be lengthened. If interest rates begin to fall, prepayments may increase, thereby shortening the estimated life of this security.
As of September 30, 2017 and December 31, 2016, we did not own securities of any one issuer (other than the U.S. government and its agencies or sponsored entities) for which the aggregate adjusted cost exceeded 10% of our consolidated shareholders’ equity.
49
The average yield of our securities portfolio was 2.60% during the nine months ended September 30, 2017 compared with 2.47% for the nine months ended September 30, 2016. The increase in average yield during the first nine months of 2017 compared to the same period in 2016 was primarily due to our increased investment in longer-term securities.
Goodwill and Core Deposit Intangible Assets
Our goodwill as of September 30, 2017 and December 31, 2016 was $39.4 million for both periods. Goodwill resulting from business combinations represents the excess of the consideration paid over the fair value of the net assets acquired and liabilities assumed. Goodwill is assessed annually for impairment or when events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable.
Our core deposit intangible assets, net as of September 30, 2017 and December 31, 2016, was $3.5 million and $4.1 million, respectively. Core deposit intangible assets are amortized using a straight-line amortization method over its estimated useful life of seven to nine years.
Deposits
Our lending and investing activities are primarily funded by deposits. We offer a variety of deposit accounts having a wide range of interest rates and terms including demand, savings, money market and certificates and other time accounts. We rely primarily on convenient locations, personalized service and our customer relationships to attract and retain these deposits. We seek customers that will both engage in a lending and deposit relationship with us.
Total deposits at September 30, 2017 were $2.29 billion, an increase of $416.4 million, or 22.3%, compared with $1.87 billion at December 31, 2016. Noninterest-bearing deposits at September 30, 2017 were $713.0 million, an increase of $119.2 million, or 20.1%, compared with $593.8 million at December 31, 2016. Interest-bearing deposits at September 30, 2017 were $1.57 billion, an increase of $297.2 million, or 23.3%, compared with $1.28 billion at December 31, 2016.
Borrowings
We have an available line of credit with the Federal Home Loan Bank ("FHLB") of Dallas, which allows us to borrow on a collateralized basis. FHLB advances are used to manage liquidity as needed. The advances are secured by a blanket lien on certain loans. Maturing advances are replaced by drawing on available cash, making additional borrowings or through increased customer deposits. At September 30, 2017, we had a total borrowing capacity of $886.6 million, of which $646.0 million was available and $240.6 million was outstanding. FHLB advances of $207.0 million were outstanding at September 30, 2017, at a weighted average interest rate of 1.32%. Letters of credit were $33.6 million at September 30, 2017, of which $25.0 million expired in October 2017 and was renewed until October 2018, $3.1 million will expire in February 2018 and $5.5 million will expire in August 2018.
Credit Agreement
In January 2015, we borrowed an additional $18.0 million under our credit agreement with another financial institution, which was in addition to the $10.1 million of indebtedness incurred under the same credit agreement in 2014. We used the funds borrowed in 2015 to repay debt that F&M Bancshares owed and used the funds borrowed in 2014 to pay off a previous borrowing with another financial institution that had been entered into during 2013 in conjunction with the acquisition of Independence Bank. In October 2015, we paid down $27.5 million of the credit agreement with a portion of the proceeds from the initial public offering of Allegiance common stock. The interest rate on the outstanding debt under the revolving credit agreement is the Prime rate minus 25 basis points, or 4.00%, at September 30, 2017, and is paid quarterly. As of September 30, 2017 and December 31, 2016, we had $569 thousand of indebtedness owed under the credit agreement. Our revolving credit agreement matures in December 2021 and is secured by 100% of the capital stock of the Bank.
The maximum commitment to advance funds under our credit agreement was originally $30.0 million, which has been and will continue to be reduced by $4.285 million on each December 22nd, beginning on December 22, 2015. We are required to repay any outstanding balance in excess of the then-current maximum commitment amount.
50
Our credit agreement contains certain restrictive covenants, including limitations on our ability to incur additional indebtedness or engage in certain fundamental corporate transactions, such as mergers, reorganizations and recapitalizations. Additionally, the Bank is required to maintain a “well-capitalized” rating, a minimum return on assets of 0.65%, measured quarterly, a ratio of loan loss reserve to nonperforming loans equal to or greater than 75%, measured quarterly, and a ratio of nonperforming assets to aggregate equity plus loan loss reserves minus intangible assets of less than 35%, measured quarterly. At September 30, 2017, the Company was in compliance with all such debt covenants, except that return on assets at the Bank was 0.47% (below the required minimum), primarily due to the unusually large provision for loan losses experienced during the quarter. Such non-compliance has been waived by the lender with respect to the quarter ended September 30, 2017.
Junior Subordinated Debentures
In connection with the F&M Bancshares acquisition, we assumed junior subordinated debentures with an aggregate original principal amount of $11.3 million and a current fair value at September 30, 2017 of $9.3 million. At acquisition, we recorded a discount of $2.5 million on the debentures. The difference between the carrying value and contractual balance will be recognized as a yield adjustment over the remaining term for the debentures.
Contractual Obligations
The following tables summarize our contractual obligations and other commitments to make future payments as of September 30, 2017 and December 31, 2016 (other than deposit obligations), which consist of our future cash payments associated with our contractual obligations pursuant to our non-cancelable operating leases and our indebtedness owed to another financial institution. Payments related to leases are based on actual payments specified in underlying contracts.

Off-Balance Sheet Items
In the normal course of business, we enter into various transactions, which, in accordance with accounting principles generally accepted in the United States, are not included in our consolidated balance sheets. We enter into these transactions to meet the financing needs of our customers. These transactions include commitments to extend credit and standby and commercial letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in our consolidated balance sheets.
Commitments to Extend Credit. We enter into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of our commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding. We minimize our exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures. The amount and type of collateral obtained, if considered necessary by us, upon extension of credit, is based on management’s credit evaluation of the customer. Management assesses the credit risk associated with certain commitments to extend credit in determining the level of the allowance for loan losses.

Standby Letters of Credit. Standby letters of credit are conditional commitments issued by us to guarantee the performance of a customer to a third party. If the customer does not perform in accordance with the terms of the agreement with the third party, we would be required to fund the commitment and we would have the rights to the underlying collateral. The maximum potential amount of future payments we could be required to make is represented by the contractual amount of the commitment. Our policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements.
As of September 30, 2017 and December 31, 2016, we had outstanding $638.4 million and $586.4 million, respectively, in commitments to extend credit and $17.0 million and $9.5 million, respectively, in commitments associated with outstanding standby letters of credit. Since commitments associated with letters of credit and commitments to extend credit may expire unused, the total outstanding may not necessarily reflect the actual future cash funding requirements.
Liquidity and Capital Resources
Liquidity
Liquidity is the measure of our ability to meet the cash flow requirements of depositors and borrowers, while at the same time meeting our operating, capital, strategic cash flow needs and to maintain reserve requirements to operate on an ongoing basis and manage unexpected events, all at a reasonable cost. During the nine months ended September 30, 2017 and the year ended December 31, 2016, our liquidity needs have been primarily met by core deposits, borrowings, security and loan maturities and amortizing investment and loan portfolios. The Bank has access to purchased funds from correspondent banks and advances from the FHLB are available under a security and pledge agreement to take advantage of investment opportunities.
Our largest source of funds is deposits, and our largest use of funds is loans. Our average loans increased $313.7 million, or 18.2%, for the nine months ended September 30, 2017 compared with the nine months ended September 30, 2016. We predominantly invest excess deposits in Federal Reserve Bank of Dallas balances, securities, interest-bearing deposits at other banks or other short-term liquid investments until the funds are needed to fund loan growth. Our securities portfolio had a weighted average life of 6.3 years and modified duration of 5.5 years at September 30, 2017, and a weighted average life of 6.7 years and modified duration of 5.8 years at December 31, 2016.
As of September 30, 2017 and December 31, 2016, we had no exposure to future cash requirements associated with known uncertainties or capital expenditures of a material nature.
Capital Resources
Capital management consists of providing equity to support our current and future operations. We are subject to capital adequacy requirements imposed by the Federal Reserve, and the Bank is subject to capital adequacy requirements imposed by the FDIC. Both the Federal Reserve and the FDIC have adopted risk-based capital requirements for assessing bank holding company and bank capital adequacy. These standards define capital and establish minimum capital requirements in relation to assets and off-balance sheet exposure, adjusted for credit risk. The risk-based capital standards currently in effect are designed to make regulatory capital requirements more sensitive to differences in risk profiles among bank holding companies and banks, to account for off-balance sheet exposure and to minimize disincentives for holding liquid assets. Assets and off-balance sheet items are assigned to broad risk categories, each with appropriate relative risk weights. The resulting capital ratios represent capital as a percentage of total risk-weighted assets and off-balance sheet items.
Under current guidelines, the minimum ratio of total capital to risk-weighted assets (which are primarily the credit risk equivalents of balance sheet assets and certain off-balance sheet items such as standby letters of credit) is 8.0%. At least half of total capital must be composed of tier 1 capital, which includes common shareholders’ equity (including retained earnings), less goodwill, other disallowed intangible assets, and disallowed deferred tax assets, among other items. The Federal Reserve also has adopted a minimum leverage ratio, requiring tier 1 capital of at least 4.0% of average quarterly total consolidated assets, net of goodwill and certain other intangible assets, for all but the most highly rated bank holding companies. The federal banking agencies have also established risk-based and leverage capital guidelines that FDIC-insured depository institutions are required to meet. These regulations are generally similar to those established by the Federal Reserve for bank holding companies.
Under the Federal Deposit Insurance Act, the federal bank regulatory agencies must take “prompt corrective action” against undercapitalized U.S. depository institutions. U.S. depository institutions are assigned one of five capital categories: “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” and “critically undercapitalized,” and are subjected to different regulation corresponding to the capital category within which the institution
52
falls. A depository institution is deemed to be “well capitalized” if the banking institution has a total risk-based capital ratio of 10.0% or greater, a tier 1 risk-based capital ratio of 8.0% or greater, a common equity Tier 1 capital ratio of 6.5% and a leverage ratio of 5.0% or greater, and the institution is not subject to an order, written agreement, capital directive or prompt corrective action directive to meet and maintain a specific level for any capital measure. Under certain circumstances, a well-capitalized, adequately capitalized or undercapitalized institution may be treated as if the institution were in the next lower capital category. In addition, the final rules implementing Basel Committee on Banking Supervision's capital guideline for U.S. Banks (Basel III Rules) became effective for us on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. Starting in January 2016, the implementation of the capital conservation buffer was effective for us starting at the 0.625% level and increasing 0.625% each year thereafter, until it reaches 2.5% on January 1, 2019.
Failure to meet capital guidelines could subject the institution to a variety of enforcement remedies by federal bank regulatory agencies, including: termination of deposit insurance by the FDIC, restrictions on certain business activities, and appointment of the FDIC as conservator or receiver. As of September 30, 2017 and December 31, 2016, the Bank was well capitalized.
Total shareholder’s equity was $302.7 million at September 30, 2017, compared with $279.8 million at December 31, 2016, an increase of $22.9 million, or 8.2%. This increase was primarily the result of net income of $14.4 million for the nine months ended September 30, 2017.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Asset/Liability Management and Interest Rate Risk
Our asset liability and interest rate risk policy provides management with the guidelines for effective balance sheet management. We have established a measurement system for monitoring our net interest rate sensitivity position. It is our objective to manage our sensitivity position within our established guidelines.
As a financial institution, a component of the market risk that we face is interest rate volatility. Fluctuations in interest rates will ultimately impact both the level of income and expense recorded on most of our assets and liabilities, and the market value of all interest-earning assets and interest-bearing liabilities, other than those which have a short term to maturity. Interest rate risk is the potential for economic losses due to future interest rate changes. These economic losses can be reflected as a loss of future net interest income and/or a loss of current fair market values. The objective is to measure the effect on net interest income and to adjust the balance sheet to minimize the inherent risk while at the same time maximizing income.
We have not entered into instruments such as leveraged derivatives, interest rate swaps, financial options, financial future contracts or forward delivery contracts for the purpose of reducing interest rate risk. Based upon the nature of our operations, we are not subject to foreign exchange rate or commodity price risk. We do not own any trading assets. We manage our exposure to interest rates by structuring our balance sheet in the ordinary course of a community banking business.
Our exposure to interest rate risk is managed by our Asset Liability Committee (“ALCO”), which is composed of certain members of our board of directors and Bank management, in accordance with policies approved by our Board of Directors. The ALCO formulates strategies based on appropriate levels of interest rate risk. In determining the appropriate level of interest rate risk, the ALCO considers the impact on earnings and capital of the current outlook on interest rates, potential changes in interest rates, regional economies, liquidity, business strategies and other factors. The ALCO meets regularly to review, among other things, the sensitivity of assets and liabilities to interest rate changes, the book and market values of assets and liabilities, unrealized gains and losses, purchase and sale activities, commitments to originate loans and the maturities of investments and borrowings. Additionally, the ALCO reviews liquidity, cash flow flexibility, maturities of deposits, and consumer and commercial deposit activity.
We use an interest rate risk simulation model and shock analysis to test the interest rate sensitivity of net interest income and the balance sheet, respectively. All instruments on the balance sheet are modeled at the instrument level, incorporating all relevant attributes such as next reset date, reset frequency, and call dates, as well as prepayment assumptions for loans and securities, and decay rates for nonmaturity deposits. Assumptions based on past experience are incorporated into the model for nonmaturity deposit account decay rates. The assumptions used are inherently uncertain and, as a result, the model cannot precisely measure future net interest income or precisely predict the impact of fluctuations in market interest rates on net interest income. Actual results will differ from the model’s simulated results due to timing, magnitude and frequency of interest rate changes as well as changes in market conditions and the application and timing of various management strategies.
We utilize static balance sheet rate shocks to estimate the potential impact on net interest income of changes in interest rates under various rate scenarios. This analysis estimates a percentage of change in the metric from the stable rate base scenario versus alternative scenarios of rising and falling market interest rates by instantaneously shocking a static balance sheet.
The following table summarizes the simulated change in net interest income and the economic value of equity over a 12-month horizon as of the dates indicated:
| Change in Interest | Percent Change in Net Interest Income | Percent Change in Economic Value of Equity |
| Rates (Basis Points) | As of September 30, 2017 | As of December 31, 2016 | As of September 30, 2017 | As of December 31, 2016 |
| +300 | (6.4)% | (3.3)% | (9.5)% | (7.4)% |
| +200 | (4.2)% | (2.3)% | (5.8)% | (4.7)% |
| +100 | (2.2)% | (1.4)% | (2.6)% | (2.3)% |
| Base | 0.0% | 0.0% | 0.0% | 0.0% |
| -100 | (2.0)% | 1.8% | (1.8)% | 1.1% |

These results are primarily due to the duration of our loan and securities portfolio and the expected behavior of demand, money market and savings deposits during such rate fluctuations.

ITEM 4. CONTROLS AND PROCEDURES
Evaluation of disclosure controls and procedures. As of the end of the period covered by this Quarterly Report on Form 10-Q, the Company carried out an evaluation, under the supervision and with the participation of its management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures. In designing and evaluating the disclosure controls and procedures, management recognizes that controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management was required to apply judgment in evaluating its controls and procedures. Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s 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”)) were effective as of the end of the period covered by this report. See Exhibits 31.1 and 31.2 for the Certification statements issued by the Company’s Chief Executive Officer and Chief Financial Officer, respectively.
Changes in internal control over financial reporting. There were no changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
PART II—OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
From time to time, we are subject to claims and litigation arising in the ordinary course of business. In the opinion of management, we are not party to any legal proceedings the resolution of which we believe would have a material adverse effect on our business, prospects, financial condition, liquidity, results of operation, cash flows or capital levels. However, one or more unfavorable outcomes in any claim or litigation against us could have a material adverse effect for the period in which such claim or litigation is resolved. In addition, regardless of their merits or their ultimate outcomes, such matters are costly, divert management’s attention and may materially adversely affect our reputation, even if resolved in our favor. We intend to defend ourselves vigorously against any future claims or litigation.
ITEM 1A. RISK FACTORS
In evaluating an investment in any of the Company’s securities, investors should consider carefully, among other things, information under the heading “Cautionary Notice Regarding Forward-Looking Statements” in this Form 10-Q, the risk factors previously disclosed under the heading “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016, and such other risk factors as the Company may disclose or has disclosed in other reports and statements filed with the Securities and Exchange Commission. In addition to the risk factors disclosed in those reports, you should note the following risk factor:
Our market is susceptible to weather events and other catastrophes that could have an adverse impact on our market's economy, our operations or our customers, any of which could have a negative effect on us.
Our business is generated primarily from the Houston MSA, which is susceptible to damage by hurricanes, tornadoes, floods, droughts and other natural disasters and adverse weather. These catastrophic events can disrupt our operations, cause widespread property damage, and severely depress the local economy in which we operate. In August 2017, our market area experienced catastrophic flooding and unprecedented storm damage due to Hurricane Harvey. The effect of Hurricane Harvey, and other catastrophic weather events if they were to occur, could have a materially adverse impact on our financial condition, results of operations and business, as well as potentially increase our exposure to credit losses and liquidity risks. If our market experiences an overall decline as a result of a catastrophic event, demand for loans and our other products and services could be reduced. In addition, the rates of delinquencies, foreclosures, bankruptcies and losses within our loan portfolio may increase substantially, as uninsured property losses or sustained job interruption or loss may materially impair the ability of borrowers to repay their loans. Moreover, the value of real estate or other collateral that secures the loans could be materially and adversely affected by a catastrophic event. A natural disaster or other catastrophic event could, therefore, result in decreased revenue and increased loan losses that could have an adverse effect on our business, financial condition and results of operations.
