BASIS OF PRESENTATION, NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES
BASIS OF PRESENTATION, NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES	NOTE 1: BASIS OF PRESENTATION, NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES Nature of Operations CBTX, Inc., or the Company, was formed on January 26, 2007, and through its subsidiary, CommunityBank of Texas, N.A., or the Bank, operates 33 locations in the Houston and Beaumont/East Texas market areas. The Company’s primary sources of revenue are from investing funds received from depositors and from providing loan and other financial services to its customers. The Bank operates under a national charter and therefore is subject to regulation by the Office of the Comptroller of the Currency, or OCC and the Federal Deposit Insurance Corporation, or FDIC. The Company is subject to regulation by the Federal Reserve Board. Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and the Bank, a wholly owned subsidiary of the Company. All material intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP, but do not include all the information and footnotes required for complete consolidated financial statements. In management’s opinion, these interim unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature necessary for a fair statement of the Company’s consolidated financial position at September 30, 2018 and December 31, 2017, consolidated results of operations for the three and nine months ended September 30, 2018 and 2017, consolidated shareholders’ equity for the nine months ended September 30, 2018 and 2017 and consolidated cash flows for the nine months ended September 30, 2018 and 2017. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year end and the results for the interim periods shown in this report are not necessarily indicative of results to be expected for the full year due in part to global economic and financial market conditions, interest rates, access to sources of liquidity, market competition and interruptions of business processes. These interim unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2017 included within our Annual Report on Form 10-K. Accounting Standards Recently Adopted Accounting Standards Update, or ASU, 2014‑09, Revenue from Contracts with Customers (Topic 606): ASU 2014‑09 requires entities to recognize revenue in a way that depicts the transfer of 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. The Company adopted ASU 2014-09 effective January 1, 2018 with no significant impact to the Company’s consolidated financial statements as the Company’s revenue is primarily comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014‑09 and noninterest income. The Company’s revenue recognition for revenue streams within the scope of ASU 2014-09, including but not limited to service charges on deposits accounts, did not materially change from previous practice. ASU, 2016‑01, Financial Instruments‑Overall (Subtopic 825‑10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this update address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016‑01, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) clarifies that entities use the exit price notion when measuring the fair value of loans for disclosure purposes and not use a practicability exception, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument‑specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (vii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available‑for‑sale investments. ASU 2018-03, Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10) clarifies certain aspects of ASU 2016-01. The Company implemented ASU 2016-01 and ASU 2018-03 effective January 1, 2018 with no significant impact to the Company’s consolidated financial statements. See Note 12 – Fair Value Disclosures. ASU 2016‑15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . ASU 2016‑15 provides guidance related to certain cash flow issues in order to reduce the current and potential future diversity in practice. The Company implemented ASU 2016‑15 effective January 1, 2018. The Company has elected to use the nature of distribution approach to determine whether income received from equity investments is operating or investing on the cash flow statement. Based on the nature of previous income streams from our equity investments, we expect these amounts will continue to be reported in cash provided by operating activities on the cash flow statement and the other items in ASU 2016-15 will be considered if such items arise. ASU 2016‑16, Income Taxes (Topic 740): Intra‑Entity Transfers of Assets Other Than Inventory . ASU 2016‑16 provides guidance stating that an entity should recognize the income tax consequences of an intra‑entity transfer of an asset other than inventory when the transfer occurs. The Company implemented ASU 2016‑16 effective January 1, 2018. As we have not historically transferred assets between entities, we expect no material impact on the consolidated financial statements and will follow this guidance for any future intra-entity transfers of assets other than inventory. ASU 2016‑18, Statement of Cash Flows (Topic 230): Restricted Cash . ASU 2016‑18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning‑of‑period and end‑of‑period total amounts shown on the statement of cash flows. The Company implemented ASU 2016‑18 effective January 1, 2018. The Company considers its Federal Bank reserves and collateral for its interest rate swaps to be restricted and these amounts were already included in cash and equivalents in the consolidated financial statements. ASU 2017‑01, Business Combinations (Topic 805): Clarifying the Definition of a Business . ASU 2017‑01 clarifies the definition and provides a more robust framework to use in determining when a set of assets and activities constitutes a business. ASU 2017‑01 is intended to provide guidance when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company implemented ASU 2017‑01 effective January 1, 2018 and will follow this guidance for any future acquisitions or dispositions. ASU 2017‑09, Compensation—Stock Compensation (Topic 718): ASU 2017-09 provides guidance about which changes in terms or conditions of a share‑based award require application of modification accounting. The Company implemented ASU 2017‑09 effective January 1, 2018 and will follow this guidance for any future modifications of share-based awards. Accounting Standards Not Yet Adopted 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 2018-10, Codification Improvements to Topic 842, Leases was issued in July 2018 to clarify narrow aspects of ASU 2016-02. In addition, ASU 2018-11, Leases (Topic 842) was also issued in July 2018 and allows application of ASU 2016-02 at the date of the adoption date and recognize a cumulative-effect adjustment to retained earnings. Prior to the issuance of ASU 2018-11, transition to the new lease accounting under ASU 2016-02 required 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. ASU 2016‑02 will be effective for the Company on January 1, 2019. The Company will use the modified retrospective approach and intends to elect the available practical expedients on adoption. This standard is anticipated to have a material impact on the Company’s consolidated balance sheets, but is not expected to have a material impact on the Company’s consolidated income statements. The Company is nearing completion of the assessment of the impacts of the standard and currently expects that the most significant impact will be an increase in assets due to the addition of right-of-use assets for assets underlying its operating leases and an increase in liabilities reflecting its liability to make the lease payments under these operating leases. ASU 2016‑13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . 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 and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. 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 will be effective on January 1, 2020. The Company is currently evaluating the potential impact of ASU 2016‑13 on the consolidated financial statements. ASU 2017‑04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminates Step 2 from the goodwill impairment test. In addition, the amendment eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. For public companies, ASU 2017‑04 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the potential impact of this pronouncement. Revenue Recognition The Company records revenue from contracts with customers in accordance with ASC 606, as applicable. A majority of the Company’s revenue-generating transactions are not subject to ASC 606, such as interest and fees on loans, income from debt securities, income from federal funds and interest-bearing deposits. Our revenue-generating activities that are within the scope of ASC 606, are included in our condensed consolidated income statements in noninterest income. See table below. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed and charged either on a periodic basis or based on activity. Nine Months Ended September 30, (Dollars in thousands) 2018 2017 Deposit account service charges $ 4,572 $ 4,412 Net gain on sale of assets 492 1,531 Card interchange fees 2,820 2,512 Deposit account service charges — – this is comprised of fees from our customers for deposit related services, such as monthly account maintenance and activity or transaction-based fees. Revenue is recognized when our performance obligation is completed which is generally monthly for account maintenance services or when a transaction is completed. Payment for such performance obligations are generally received at the time the performance obligation is satisfied. Net gain on sale of assets — – this is comprised of gains on sales of fixed assets, gains on sales of loans and gains on sales of other real estate owned, or OREO. Gains on sales of loans are excluded from ASC 606. The performance obligation in the sale of OREO or fixed assets is delivery of control over the property to the buyer. The Company does not typically provide financing and the transaction price is identified in the purchase and sale agreement. If the Company provides financing, the Company must determine a transaction price depending on if the sales contract is at market terms and taking into account the credit risk inherent in the sale agreement. Card interchange fees — – this is comprised of fees generated from debit card transactions. Revenue is recognized when our performance obligation is completed generally when a transaction is completed.

Securities with a carrying amount of $6.6 million and $6.1 million were sold in the nine months ended September 30, 2018 and 2017, respectively. At September 30, 2018 and December 31, 2017, debt securities with a carrying amount of approximately $43.5 million and $58.7 million, respectively, were pledged to secure public deposits and for other purposes required or permitted by law. The Company held 74 debt securities at September 30, 2018 and 52 debt securities at December 31, 2017, that were in a gross unrealized loss position for 12 months or more as illustrated in the table below. The unrealized losses are attributable primarily to changes in market interest rates relative to those available when the debt securities were acquired. The fair value of these debt securities is expected to recover as the debt securities reach their maturity or re‑pricing date, or if changes in market rates for such investments decline. Management does not believe that any of the debt securities are impaired due to reasons of credit quality. Accordingly, as of September 30, 2018 and December 31, 2017, management believes the unrealized losses detailed in the table below are temporary and no impairment loss has been recorded in the Company’s condensed consolidated statements of income for the nine months ended September 30, 2018 and 2017.

A significant portion of the loans modified as troubled debt restructurings by the Company were previously on nonaccrual status and reported as impaired loans prior to restructuring and as a result, the modifications did not impact the Company’s determination of the allowance for loan losses. The recorded investment in troubled debt restructurings was $16.2 million and $18.2 million as of September 30, 2018 and December 31, 2017, respectively. As of September 30, 2018 and December 31, 2017, $4.7 million and $4.8 million of restructured loans were nonaccrual loans and $11.5 million and $13.4 million of restructured loans were accruing interest as of those periods. At September 30, 2018, the Company has an outstanding commitment to potentially fund $103,000 on a line of credit restructured prior to 2018. At December 31, 2017, the Company had no commitments to loan additional funds to borrowers with loans that were restructured. There were no loans modified as a troubled debt restructured loan within the previous 12 months and for which there was a payment default. For purposes of this disclosure, a default is a loan modified as a troubled debt restructuring where the borrower is 90 days past due or results in the foreclosure and repossession of the applicable collateral.

ALLOWANCE FOR LOAN LOSSES
ALLOWANCE FOR LOAN LOSSES	NOTE 5: ALLOWANCE FOR LOAN LOSSES For purposes of determining the allowance for loan losses, the Company considers the loans in its portfolio by segment, class and risk grade. Management uses judgment to determine the estimation method that fits the credit risk characteristics of each portfolio segment or class. To facilitate the assessment of risk, management reviews reports related to loan production, loan quality, concentrations of credit, loan delinquencies and nonperforming and potential problem loans. The Company utilizes an independent third-party loan review service to review the credit risk assigned to loans on a periodic basis and the results are presented to management for review. Activity in the allowance for loan losses segregated by loan class for the nine months ended September 30, 2018 and 2017 and the year ended December 31, 2017 was as follows: Real Estate Commercial Construction and Commercial and 1-4 family Multi-family (Dollars in thousands) industrial real estate development residential residential Consumer Agriculture Other Total September 30, 2018 Beginning balance $ 7,257 $ 10,375 $ 3,482 $ 1,326 $ 1,419 $ 566 $ 68 $ 285 $ 24,778 Provision (recapture) for loan loss 2,218 (3,467) 124 1,126 211 (173) 3 371 413 Charge-offs (1,136) (9) — (3) — (1) — (3) (1,152) Recoveries 424 14 — 5 — 2 — 2 447 Net (charge-offs) recoveries (712) 5 — 2 — 1 — (1) (705) Ending balance $ 8,763 $ 6,913 $ 3,606 $ 2,454 $ 1,630 $ 394 $ 71 $ 655 $ 24,486 Period-end amount allocated to: Specific reserve $ 542 $ 1 $ — $ 115 $ — $ — $ — $ 127 $ 785 General reserve 8,221 6,912 3,606 2,339 1,630 394 71 528 23,701 Total $ 8,763 $ 6,913 $ 3,606 $ 2,454 $ 1,630 $ 394 $ 71 $ 655 $ 24,486 Real Estate Commercial Construction and Commercial and 1-4 family Multi-family (Dollars in thousands) industrial real estate development residential residential Consumer Agriculture Other Total December 31, 2017 Beginning balance $ 6,409 $ 10,770 $ 4,598 $ 1,286 $ 916 $ 353 $ 79 $ 595 $ 25,006 Provision (recapture) for loan loss 642 (284) (1,116) 35 503 263 (63) (318) (338) Charge-offs (904) (120) — (8) — (93) — — (1,125) Recoveries 1,110 9 — 13 — 43 52 8 1,235 Net (charge-offs) recoveries 206 (111) — 5 — (50) 52 8 110 Ending balance $ 7,257 $ 10,375 $ 3,482 $ 1,326 $ 1,419 $ 566 $ 68 $ 285 $ 24,778 Period-end amount allocated to: Specific reserve $ 852 $ 64 $ — $ 119 $ — $ — $ — $ — $ 1,035 General reserve 6,405 10,311 3,482 1,207 1,419 566 68 285 23,743 Total $ 7,257 $ 10,375 $ 3,482 $ 1,326 $ 1,419 $ 566 $ 68 $ 285 $ 24,778 Real Estate Commercial Construction and Commercial and 1-4 family Multi-family (Dollars in thousands) industrial real estate development residential residential Consumer Agriculture Other Total September 30, 2017 Beginning balance $ 6,409 $ 10,770 $ 4,598 $ 1,286 $ 916 $ 353 $ 79 $ 595 $ 25,006 Provision (recapture) for loan loss 631 (1,137) (1,234) (16) 444 332 (27) (381) (1,388) Charge-offs (791) — — — — (83) — — (874) Recoveries 945 7 — 12 — 24 17 8 1,013 Net (charge-offs) recoveries 154 7 — 12 — (59) 17 8 139 Ending balance $ 7,194 $ 9,640 $ 3,364 $ 1,282 $ 1,360 $ 626 $ 69 $ 222 $ 23,757 Period-end amount allocated to: Specific reserve $ 424 $ — $ — $ 132 $ — $ — $ — $ — $ 556 General reserve 6,770 9,640 3,364 1,150 1,360 626 69 222 23,201 Total $ 7,194 $ 9,640 $ 3,364 $ 1,282 $ 1,360 $ 626 $ 69 $ 222 $ 23,757 Allocation of a portion of the allowance to one category of loans in the tables above does not preclude its availability to absorb losses in other categories. In addition to the amounts indicated in the tables above, the Company has an accumulated reserve for loan losses on unfunded commitments of $378,000 and $378,000 recorded in other liabilities as of September 30, 2018 and December 31, 2017, respectively. Risk Grading As part of the on‑going monitoring of the credit quality of the Company’s loan portfolio and methodology for calculating the allowance for loan losses, management assigns and tracks loan grades to be used as credit quality indicators. The following is a general description of the loan grades the Company used as of September 30, 2018 and December 31, 2017: Pass —Credits in this category are considered “pass ” which indicates prudent underwriting and a normal amount of risk. The range of risk within these credits can vary from little to no risk with cash securing a credit, to a level of risk that requires a strong secondary source of repayment on the debt. Pass credits with a higher level of risk may be to borrowers that are higher leveraged, less well capitalized or in an industry or economic area that is known to carry a higher level of risk, volatility, or susceptibility to weaknesses in the economy. This higher risk grade may be assigned due to out of date credit information, as well as collateral information which may need to be updated for current market value in order to allow a credit quality analysis of the credit. Special Mention —Credits in this category contain more than the normal amount of risk and are referred to as “special mention” in accordance with regulatory guidelines. These credits possess clearly identifiable temporary weaknesses or trends that, if not corrected or revised, may result in a condition that exposes the Company to higher level of risk of loss. Substandard —Credits in this category are “substandard” in accordance with regulatory guidelines and of unsatisfactory credit quality with well‑defined weaknesses or weaknesses that jeopardize the liquidation of the debt. Credits in this category are inadequately protected by the current sound worth and paying capacity of the obligor or the collateral pledged, if any. These credits are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Often, the assets in this category will have a valuation allowance representative of management’s estimated loss that is probable to be incurred. Substandard loans may also be placed on nonaccrual status as deemed appropriate by management. Loans substandard and on nonaccrual status are considered impaired and are evaluated for impairment. Doubtful —Credits in this category are considered “doubtful” in accordance with regulatory guidelines, are placed on nonaccrual status and may be dependent upon collateral having a value that is difficult to determine or upon some near‑term event which lacks certainty. Generally, these credits will have a valuation allowance based upon management’s best estimate of the losses probable to occur in the liquidation of the debt. Loss —Credits in this category are considered “loss” in accordance with regulatory guidelines and are considered uncollectible and of such little value as to question their continued existence as assets on the Company’s financial statements. Such credits are to be charged off or charged down when payment is acknowledged to be uncertain or when the timing or value of payments cannot be determined. This category does not intend to imply that the debt or some portion of it will never be paid, nor does it in any way imply that the debt will be forgiven.

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	9 Months Ended

FAIR VALUE DISCLOSURES
FAIR VALUE DISCLOSURES	NOTE 12: FAIR VALUE DISCLOSURES The Company uses fair value measurements to record fair value adjustments to certain assets and to determine fair value disclosures. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction occurring in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. In estimating fair value, we use valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement costs). Such valuation techniques are consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. Valuation inputs are categorized in a three-level hierarchy, from highest to lowest level of observable inputs. The highest level of inputs are prices in active markets for identical assets or liabilities and the lowest level of inputs are unobservable inputs. The fair value hierarchy is as follows: Level 1 Inputs —Inputs are based upon unadjusted quoted prices in active markets for identical assets and liabilities that the reporting entity has the ability to access at the measurement date. Level 2 Inputs —Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 2 investments consist primarily of obligations of U.S. government sponsored enterprises and agencies, obligations of state and municipal subdivisions, corporate bonds and mortgage‑backed securities. Level 3 Inputs —Significant unobservable inputs that reflect an entity’s own assumptions that market participants would use in pricing the assets or liabilities. During the nine months ending September 30, 2018 and the year ended December 31, 2017, there were no transfers of assets or liabilities within the levels of the fair value hierarchy. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use observable market‑based parameters as inputs. Valuation adjustments may be made to ensure that assets and liabilities are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Financial Instruments Recorded at Fair Value Assets and liabilities measured at fair value on a recurring basis include the following: Debt Securities Available for Sale: Debt securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For those debt securities classified as Level 2, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayments speeds, credit information and the bond’s terms and conditions, among other things. The other securities in the table below are mutual funds and the fair value is determined by using unadjusted quoted market prices which are considered Level 1 inputs. Interest Rate Swaps with Customers: For interest rate swaps with customers classified as Level 2, the Company obtains fair value measurements from an independent pricing service which uses the income approach. The income approach calls for the utilization of valuation techniques to convert future cash flows as due to be exchanged per the terms of the financial instrument, into a single present value amount. Measurement is based on the value indicated by the market expectations about those future amounts as of the measurement date. The proprietary curves of the independent pricing service utilize pricing models derived from industry standard analytic tools, considering both Level 1 and Level 2 inputs. Interest Rate Swaps with Financial Institutions: For interest rate swaps with financial institutions classified as Level 2, the Company obtains fair value measurements from an independent pricing service which uses the income approach. The income approach calls for the utilization of valuation techniques to convert future cash flows as due to be exchanged per the terms of the financial instrument, into a single present value amount. Measurement is based on the value indicated by the market expectations about those future amounts as of the measurement date. The proprietary curves of the independent pricing service utilize pricing models derived from industry standard analytic tools, taking into account both Level 1 and Level 2 inputs. The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of the dates shown below, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value.

Financial assets measured at fair value on a non‑recurring basis during the reported periods include certain impaired loans reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. Repossessed real estate and other assets as well as collateral values are estimated using Level 2 inputs based on observable market data, typically in the case of real estate collateral, or Level 3 inputs based on customized discounting criteria, typically in the case of non‑real estate collateral such as inventory, accounts receivable, equipment or other business assets. Certain assets measured at fair value on a non‑recurring basis as of the dates shown below were as follows: September 30, 2018 December 31, 2017 Level 3 Level 3 (Dollars in thousands) Inputs Inputs Impaired loans: Commercial and industrial $ — $ 340 Commercial real estate 603 603 1-4 family residential 1,722 1,755 Other 8,205 — Total impaired loans $ 10,530 $ 2,698 Non‑Financial Assets and Non‑Financial Liabilities The Company does not have any non‑financial assets or non‑financial liabilities measured at fair value on a recurring basis. Certain non‑financial assets measured at fair value on a non‑recurring basis include foreclosed assets (upon initial recognition or subsequent impairment), non‑financial assets and non‑financial liabilities measured at fair value in the second step of a goodwill impairment test and intangible assets and other non‑financial long‑lived assets measured at fair value for impairment assessment. Non‑financial assets measured at fair value on a non‑recurring basis during the reported periods include certain foreclosed assets which, upon initial recognition, were remeasured and reported at fair value through a charge‑off to the allowance for loan losses and certain foreclosed assets which, subsequent to their initial recognition, were remeasured at fair value through a write‑down included in other non‑interest expense. The fair value of a foreclosed asset is estimated using Level 2 inputs based on observable market data or Level 3 inputs based on customized discounting criteria. During the nine months ended September 30, 2018 and during 2017, we used Level 2 inputs for our fair value measurements for foreclosed assets.

However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. The fair value of loans is determined using a discounted cash flow analyses and includes such factors as credit and prepayment risk and economic forecasts for interest rates in accordance with ASU 2016-01. Equity Investments — The Company has unconsolidated investments that are considered equity securities meaning they represent ownership interests (such as common or preferred stock). Our equity investments do not have readily determinable fair values and are shown in the table below for the dates indicated. September 30, December 31, (Dollars in thousands) 2018 2017 Federal Reserve stock $ 9,271 $ 9,271 Federal Home Loan Bank stock 3,294 1,189 The Independent Bankers Financial Corporation stock 141 141 Community Reinvestment Act investments 2,395 1,625 Total $ 15,101 $ 12,226 Banks that are members of the FHLB, are required to maintain a stock investment in the FHLB calculated as a percentage of aggregate outstanding mortgages, outstanding FHLB advances and other financial instruments. Banks that are members of the Federal Reserve System are required to annually subscribe to Federal Reserve Bank stock in specific ratios to the Bank’s equity. Although FHLB and Federal Reserve Bank Stock are considered equity securities, they do not have readily determinable fair values because ownership is restricted and they lack a market. These investments can be sold back only at their par value of $100 per share and can only be sold to the Federal Home Loan Banks or Federal Reserve Banks or to another member institution. In addition, the equity ownership rights are more limited than would be the case for a public company, because of the oversight role exercised by regulators in the process of budgeting and approving dividends. As a result, these investments are carried at cost and evaluated for impairment. The Company also holds an investment in the stock of The Independent Bankers Financial Corporation, or TIB. This investment has limited marketability. As a result, these investments are carried at cost and evaluated for impairment. The Company has investments in two private investment funds and a limited partnership. These investments are qualified Community Reinvestment Act, or CRA, investments under the Small Business Investment Company program of the SBA. There are limited to no observable price changes in orderly transactions for identical investments or similar investments from the same issuers that are actively traded and as a result, these investments are stated at cost. Our equity investments are evaluated for impairment based on an assessment of qualitative indicators. Impairment indicators to be considered include, but are not limited to (i) a significant deterioration in the earnings, performance, credit rating, asset quality or business prospects of the investee, (ii) a significant adverse change in the regulatory, economic or technological environment of the investee, (iii) a significant adverse change in the general market conditions of either the geographical area or the industry in which the investee operates, (iv) a bona fide offer to purchase, an offer by the investee to sell, or completed auction process for the same or similar investment for an amount less that the carrying amount of that investment. There were no such qualitative indicators as of September 30, 2018.

COMMITMENTS AND CONTINGENCIES, INCLUDING FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK
COMMITMENTS AND CONTINGENCIES, INCLUDING FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK	NOTE 13 COMMITMENTS AND CONTINGENCIES AND FINANCIAL INSTRUMENTS WITH OFF‑BALANCE‑SHEET RISK Unfunded Loan Commitments The Company is party to various financial instruments with off‑balance‑sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit for loans in process, commercial lines of credit, overdraft protection lines, and standby letters of credit at both fixed and variable rates of interest. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of the involvement the Company has in particular classes of financial instruments. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Company uses the same credit policies in making these commitments and conditional obligations as it does for on‑balance‑sheet instruments. The Company evaluates each customer’s credit worthiness on a case‑by‑case basis. The amount of collateral obtained, if considered necessary by the Company upon extension of credit, is based on management’s credit evaluation of the customer. Commitments to extend credit and standby letters of credit as of the dates shown below were as follows: September 30, December 31, (Dollars in thousands) 2018 2017 Commitments to extend credit, variable $ 737,355 $ 626,441 Commitments to extend credit, fixed 93,007 61,608 $ 830,362 $ 688,049 Standby letters of credit $ 26,485 $ 28,977 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being fully drawn upon, the total commitment amounts disclosed above do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to our customers. Derivative Financial Instruments The Company has outstanding interest rate swap contracts in which the Bank entered into an interest rate swap with a customer and entered into an offsetting interest rate swap with another financial institution at the same time. These interest rate swap contracts are not designated as hedging instruments for mitigating interest rate risk of the Bank. The objective of the transactions is to allow the Bank’s customers to effectively convert a variable rate loan to a fixed rate. In connection with each swap transaction, the Bank agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, the Bank agrees to pay a third‑party financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. Because the Bank acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts are designed to offset each other and would not significantly impact the Company’s operating results except in certain situations where there is a significant deterioration in the customer’s credit worthiness or that of the counterparties. At September 30, 2018 and December 31, 2017, no such deterioration was determined by management. At September 30, 2018 and December 31, 2017, the Company had 12 and 14 interest rate swap agreements outstanding with borrowers and financial institutions, respectively. These derivative instruments are not designated as accounting hedges and changes in the net fair value are recognized in noninterest income or expense. Fair value amounts are included in other assets and other liabilities. Derivative instruments outstanding as of as of the dates listed shown were as follows: Weighted Notional Fair Average (Dollars in thousands) Classification Amounts Value Fixed Rate Floating Rate Maturity September 30, 2018 Interest rate swaps with customers Other Assets $ 3,296 $ 7 5.89% - 7.25% LIBOR 1M + 3.00% - 3.20% 2.96 years Interest rate swaps with financial institution Other Assets 35,556 1,708 4.00% - 5.65% LIBOR 1M + 2.50% - 3.25% 7.89 years Interest rate swaps with customers Other Liabilities 35,556 (1,708) 4.00% - 5.65% LIBOR 1M + 2.50% - 3.25% 7.89 years Interest rate swaps with financial institution Other Liabilities 3,296 (7) 5.89% - 7.25% LIBOR 1M + 3.00% - 3.20% 2.96 years Total derivatives not designated as hedging instruments $ 77,704 $ — Weighted Notional Fair Average (Dollars in thousands) Classification Amounts Value Fixed Rate Floating Rate Maturity December 31, 2017 Interest rate swaps with customers Other Assets $ 25,882 $ 340 4.75% - 7.25% LIBOR 1M + 2.50% - 3.20% 7.83 years Interest rate swaps with financial institution Other Assets 16,579 426 4.00% - 5.15% LIBOR 1M + 2.50% - 3.25% 8.12 years Interest rate swaps with customers Other Liabilities 16,579 (426) 4.00% - 5.15% LIBOR 1M + 2.50% - 3.25% 8.12 years Interest rate swaps with financial institution Other Liabilities 25,882 (340) 4.75% - 7.25% LIBOR 1M + 2.50% - 3.20% 7.83 years Total derivatives not designated as hedging instruments $ 84,922 $ — Repurchase Agreements At September 30, 2018 and December 31, 2017, the Company had outstanding funds amounting to $1.4 million and $1.5 million respectively, received from the sale of securities that were sold under agreements to repurchase. Securities subject to the transfer of ownership under the repurchase agreements are included in pledged securities, and the carrying value of these securities is disclosed in Note 2. The Company transacts these repurchase agreements with its customers and pays interest rates on these funds according to the terms of each repurchase agreement. Contingent Liabilities The Company is committed to contribute capital into two private investment funds and a limited partnership under the Small Business Investment Company program of the SBA. At September 30, 2018 and December 31, 2017, the Company had $3.0 million and $3.8 million, respectively, in outstanding unfunded commitments to these funds which are subject to call. Cumulative capital contributions to these funds of $2.4 million and $1.6 million are included in other investments in the Company’s condensed consolidated balance sheets at September 30, 2018 and December 31, 2017, respectively. The Company is subject to claims and lawsuits which arise primarily in the ordinary course of business. Based on information presently available and advice received from legal counsel representing the Company, it is the opinion of management that the disposition or ultimate determination of such claims and lawsuits will not have a material adverse effect on the financial position or results of operations of the Company. Lease Commitments The Company leases several of its banking facilities under operating leases. Total rent expense for operating leases of premises and equipment was approximately $1.4 million and $1.4 million for the nine months ended September 30, 2018 and 2017, respectively, and is reflected in net occupancy expense on the condensed consolidated statements of income.

EMPLOYEE BENEFIT PLANS AND DEFERRED COMPENSATION ARRANGEMENTS
EMPLOYEE BENEFIT PLANS AND DEFERRED COMPENSATION ARRANGEMENTS	NOTE 14: EMPLOYEE BENEFIT PLANS AND DEFERRED COMPENSATION ARRANGEMENTS Employee Benefit Plans The Company maintains a 401(k) employee benefit plan in which substantially all employees that complete three months of service may participate. The Company, at its discretion, may match a portion of each employee’s contribution. The Company, also at its discretion, may make additional contributions during the Plan year. For the nine months ended September 30, 2018 and 2017, the Company contributed $1.4 million and $1.3 million to the plan, respectively. Executive Deferred Compensation Arrangements The Company established an executive incentive compensation arrangement with several officers of the Bank, in which these officers are eligible for performance based incentive bonus compensation. As part of this compensation arrangement, the Company will contribute one‑fourth of the incentive bonus amount into a deferred compensation account. The deferred amounts accrue a market rate of interest and are payable to the employees upon separation from the Bank provided the Plan’s vesting arrangements have been met. At September 30, 2018 and December 31, 2017, the amount payable, including interest, for this deferred plan was approximately $2.5 million and $2.4 million respectively, and is included in other liabilities in the condensed consolidated balance sheets. Salary Continuation Agreements The Company entered into a salary continuation arrangement in 2008 with the Company’s then President and CEO that calls for payments of $100,000 per year for a period of 10 years commencing at age 65. Payments under the plan began during 2014. The Company’s liability was approximately $441,000 and $503,000 at September 30, 2018 and December 31, 2017, respectively, determined using discounted cash flows and is included in other liabilities in the condensed consolidated balance sheets. In October 2017, the Company entered into a salary continuation arrangement with the Company’s President and CEO that calls for payments of $200,000 per year payable for a period of 10 years commencing at age 70. Payments under the plan will begin in 2024. The Company’s liability was approximately $195,000 and $32,000 at September 30, 2018 and December 31, 2017, determined using discounted cash flows and is included in other liabilities in the condensed consolidated balance sheets. Change of Control Agreements In 2017, the Company entered into employment agreements with certain executive officers. These agreements provide for severance benefits if we terminate the executive without cause or the executive resigns with good reason, as defined in the agreements. In addition, upon a change of control, as that term is defined in the agreements, these employees will be entitled to an aggregate amount estimated to be $4.1 million at September 30, 2018, in accordance with the terms of their respective agreements. No compensation has been recorded to date as a change of control condition is not deemed probable. VB Texas, Inc. and Vista Bank Texas entered into change of control and non‑competition agreements with certain employees of VB Texas, Inc., who are now employees of the Bank. The Company’s initial public offering completed November 10, 2017 triggered the change of control provisions of these agreement and we paid these employees an aggregate amount of $2.5 million during the nine months ended September 30, 2018.

STOCK-BASED COMPENSATION
STOCK-BASED COMPENSATION	NOTE 15: STOCK-BASED COMPENSATION The Company acquired a stock option plan which originated under VB Texas, Inc. as a part of a merger of the two companies. The options granted to employees must be exercised within 10 years from the date of grant and vesting schedules are determined on an individual basis. At the merger date, all outstanding options became fully vested and were converted to options of the Company’s common stock at an exchange ratio equal to the acquisition exchange rate for common shares. No options were granted under this plan after October 24, 2016. The Company also acquired a stock option plan that originated in May 2011 under VB Texas, Inc., or the 2011 Plan. At the merger date, all outstanding options became fully vested and were converted to options of the Company’s common stock at an exchange ratio equal to the acquisition exchange rate for common shares. The 2011 Plan was terminated on August 7, 2017 and as of that date, there were no options outstanding under this plan. In May 2014, the Company adopted the 2014 Stock Option Plan, or the 2014 Plan. The 2014 Plan was approved by the Company’s shareholders and limits the number of shares that may be optioned to 1,127,200. The 2014 Plan provides that no options may be granted after May 20, 2024. Options granted under the 2014 Plan expire 10 years from the date of grant and become exercisable in installments over a period of one to five years, beginning on the first anniversary of the date of grant. At September 30, 2018, 959,200 options were available for future grant under the 2014 Plan. On September 13, 2017, the Company’s shareholders approved the Company’s 2017 Omnibus Incentive Plan, or the 2017 Plan. The 2017 Plan authorizes the Company to grant options and restricted stock awards as well as various other types of stock-based and other awards that are not stock-based to eligible employees, consultants and non‑employee directors up to an aggregate of 600,000 shares of common stock. At September 30, 2018, 368,920 share-based awards were available for future grant under the 2017 Plan.

The market value of the Company’s common stock at the date of grant is used as the estimate of fair value of restricted stock. The shares of the restricted stock are fully issued at the time of the grant and the grantee becomes the record owner of the restricted stock and has voting, dividend and other shareholder rights. The shares of restricted stock are non-transferable and subject to forfeiture until the restricted stock vests and any dividends with respect to the restricted stock are subject to the same restrictions, including the risk of forfeiture. At September 30, 2018, $44,000 was accrued for dividends payable to restricted stock holders. These dividends will be paid upon vesting of the restricted stock. The following tables summarizes our restricted stock awards as of the date shown below.

As of September 30, 2018, there was approximately $5.4 million of total unrecognized compensation expense related to the stock‑based compensation arrangements, which is expected to be recognized in the Company’s consolidated statements of income over a weighted-average period of 3.8 years.

REGULATORY MATTERS

REGULATORY MATTERS	9 Months Ended

REGULATORY MATTERS
REGULATORY MATTERS	NOTE 16: REGULATORY MATTERS Regulatory Capital Banks and bank holding companies are subject to various regulatory capital requirements administered by state and federal banking agencies. Capital adequacy guidelines and, additionally 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 weighting and other factors. The Company and Bank’s Common Equity Tier 1 capital includes common stock and related capital surplus, net of treasury stock, and retained earnings. In connection with the adoption of the Basel III Capital Rules, the Company and Bank elected to opt‑out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1. Common Equity Tier 1 for both the Company and Bank is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities, and subject to transition provisions. When fully phased in on January 1, 2019, the Basel III Capital Rules will require the Company and Bank to maintain (i) a minimum ratio of Common Equity Tier 1 capital to risk‑weighted assets of at least 4.5%, plus a 2.5% “capital conservation buffer” (which is added to the 4.5% Common Equity Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum ratio of Common Equity Tier 1 capital to risk‑weighted assets of at least 7.0% upon full implementation), (ii) a minimum ratio of Tier 1 capital to risk‑weighted assets of at least 6.0%, plus the capital conservation buffer (which is added to the 6.0% Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum Tier 1 capital ratio of 8.5% upon full implementation), (iii) a minimum ratio of Total capital (that is, Tier 1 plus Tier 2) to risk‑weighted assets of at least 8.0%, plus the capital conservation buffer (which is added to the 8.0% total capital ratio as that buffer is phased in, effectively resulting in a minimum total capital ratio of 10.5% upon full implementation) and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average quarterly assets. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and will be phased in over a four‑year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). The Basel III Capital Rules also provide for a “countercyclical capital buffer” that is applicable to only certain covered institutions and does not have any current applicability to the Company and Bank. The capital conservation buffer is designed to absorb losses during periods of economic stress and, as detailed above, effectively increases the minimum required risk‑weighted capital ratios. Banking institutions with a ratio of Common Equity Tier 1 capital to risk‑weighted assets below the effective minimum (4.5% plus the capital conservation buffer and, if applicable, the countercyclical capital buffer) will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. The following table presents actual and required capital ratios as of the dates shown below for the Company and Bank.

The Company and Bank are subject to the regulatory capital requirements administered by the Federal Reserve Board and, for the Bank, the OCC. Regulatory authorities can initiate certain mandatory actions if the Company or the Bank fail to meet the minimum capital requirements, which could have a direct material effect on our financial statements. Management believes, as of September 30, 2018 and December 31, 2017, that the Company and the Bank meet all capital adequacy requirements to which they are subject. Dividend Restrictions In the ordinary course of business, the Company may be dependent upon dividends from the Bank to provide funds for the payment of dividends to shareholders and to provide for other cash requirements. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels. Approval is also required if dividends declared exceed the net profits for that year combined with the retained net profits for the preceding two years.

EARNINGS PER SHARE
EARNINGS PER SHARE	NOTE 18: EARNINGS PER SHARE Basic earnings per common share is computed as net income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share is computed using the weighted‑average number of 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. The following table illustrates the computation of basic and diluted earnings per share for the dates shown below.

BASIS OF PRESENTATION, NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and the Bank, a wholly owned subsidiary of the Company. All material intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP, but do not include all the information and footnotes required for complete consolidated financial statements. In management’s opinion, these interim unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature necessary for a fair statement of the Company’s consolidated financial position at September 30, 2018 and December 31, 2017, consolidated results of operations for the three and nine months ended September 30, 2018 and 2017, consolidated shareholders’ equity for the nine months ended September 30, 2018 and 2017 and consolidated cash flows for the nine months ended September 30, 2018 and 2017. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year end and the results for the interim periods shown in this report are not necessarily indicative of results to be expected for the full year due in part to global economic and financial market conditions, interest rates, access to sources of liquidity, market competition and interruptions of business processes. These interim unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2017 included within our Annual Report on Form 10-K.
Accounting Standards Recently Adopted	Accounting Standards Recently Adopted Accounting Standards Update, or ASU, 2014‑09, Revenue from Contracts with Customers (Topic 606): ASU 2014‑09 requires entities to recognize revenue in a way that depicts the transfer of 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. The Company adopted ASU 2014-09 effective January 1, 2018 with no significant impact to the Company’s consolidated financial statements as the Company’s revenue is primarily comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014‑09 and noninterest income. The Company’s revenue recognition for revenue streams within the scope of ASU 2014-09, including but not limited to service charges on deposits accounts, did not materially change from previous practice. ASU, 2016‑01, Financial Instruments‑Overall (Subtopic 825‑10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this update address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016‑01, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) clarifies that entities use the exit price notion when measuring the fair value of loans for disclosure purposes and not use a practicability exception, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument‑specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (vii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available‑for‑sale investments. ASU 2018-03, Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10) clarifies certain aspects of ASU 2016-01. The Company implemented ASU 2016-01 and ASU 2018-03 effective January 1, 2018 with no significant impact to the Company’s consolidated financial statements. See Note 12 – Fair Value Disclosures. ASU 2016‑15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . ASU 2016‑15 provides guidance related to certain cash flow issues in order to reduce the current and potential future diversity in practice. The Company implemented ASU 2016‑15 effective January 1, 2018. The Company has elected to use the nature of distribution approach to determine whether income received from equity investments is operating or investing on the cash flow statement. Based on the nature of previous income streams from our equity investments, we expect these amounts will continue to be reported in cash provided by operating activities on the cash flow statement and the other items in ASU 2016-15 will be considered if such items arise. ASU 2016‑16, Income Taxes (Topic 740): Intra‑Entity Transfers of Assets Other Than Inventory . ASU 2016‑16 provides guidance stating that an entity should recognize the income tax consequences of an intra‑entity transfer of an asset other than inventory when the transfer occurs. The Company implemented ASU 2016‑16 effective January 1, 2018. As we have not historically transferred assets between entities, we expect no material impact on the consolidated financial statements and will follow this guidance for any future intra-entity transfers of assets other than inventory. ASU 2016‑18, Statement of Cash Flows (Topic 230): Restricted Cash . ASU 2016‑18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning‑of‑period and end‑of‑period total amounts shown on the statement of cash flows. The Company implemented ASU 2016‑18 effective January 1, 2018. The Company considers its Federal Bank reserves and collateral for its interest rate swaps to be restricted and these amounts were already included in cash and equivalents in the consolidated financial statements. ASU 2017‑01, Business Combinations (Topic 805): Clarifying the Definition of a Business . ASU 2017‑01 clarifies the definition and provides a more robust framework to use in determining when a set of assets and activities constitutes a business. ASU 2017‑01 is intended to provide guidance when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company implemented ASU 2017‑01 effective January 1, 2018 and will follow this guidance for any future acquisitions or dispositions. ASU 2017‑09, Compensation—Stock Compensation (Topic 718): ASU 2017-09 provides guidance about which changes in terms or conditions of a share‑based award require application of modification accounting. The Company implemented ASU 2017‑09 effective January 1, 2018 and will follow this guidance for any future modifications of share-based awards. Accounting Standards Not Yet Adopted 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 2018-10, Codification Improvements to Topic 842, Leases was issued in July 2018 to clarify narrow aspects of ASU 2016-02. In addition, ASU 2018-11, Leases (Topic 842) was also issued in July 2018 and allows application of ASU 2016-02 at the date of the adoption date and recognize a cumulative-effect adjustment to retained earnings. Prior to the issuance of ASU 2018-11, transition to the new lease accounting under ASU 2016-02 required 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. ASU 2016‑02 will be effective for the Company on January 1, 2019. The Company will use the modified retrospective approach and intends to elect the available practical expedients on adoption. This standard is anticipated to have a material impact on the Company’s consolidated balance sheets, but is not expected to have a material impact on the Company’s consolidated income statements. The Company is nearing completion of the assessment of the impacts of the standard and currently expects that the most significant impact will be an increase in assets due to the addition of right-of-use assets for assets underlying its operating leases and an increase in liabilities reflecting its liability to make the lease payments under these operating leases. ASU 2016‑13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . 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 and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. 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 will be effective on January 1, 2020. The Company is currently evaluating the potential impact of ASU 2016‑13 on the consolidated financial statements. ASU 2017‑04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminates Step 2 from the goodwill impairment test. In addition, the amendment eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. For public companies, ASU 2017‑04 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the potential impact of this pronouncement.
Revenue Recognition	Revenue Recognition The Company records revenue from contracts with customers in accordance with ASC 606, as applicable. A majority of the Company’s revenue-generating transactions are not subject to ASC 606, such as interest and fees on loans, income from debt securities, income from federal funds and interest-bearing deposits. Our revenue-generating activities that are within the scope of ASC 606, are included in our condensed consolidated income statements in noninterest income. See table below. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed and charged either on a periodic basis or based on activity. Nine Months Ended September 30, (Dollars in thousands) 2018 2017 Deposit account service charges $ 4,572 $ 4,412 Net gain on sale of assets 492 1,531 Card interchange fees 2,820 2,512 Deposit account service charges — – this is comprised of fees from our customers for deposit related services, such as monthly account maintenance and activity or transaction-based fees. Revenue is recognized when our performance obligation is completed which is generally monthly for account maintenance services or when a transaction is completed. Payment for such performance obligations are generally received at the time the performance obligation is satisfied. Net gain on sale of assets — – this is comprised of gains on sales of fixed assets, gains on sales of loans and gains on sales of other real estate owned, or OREO.

The Company does not typically provide financing and the transaction price is identified in the purchase and sale agreement. If the Company provides financing, the Company must determine a transaction price depending on if the sales contract is at market terms and taking into account the credit risk inherent in the sale agreement. Card interchange fees — – this is comprised of fees generated from debit card transactions. Revenue is recognized when our performance obligation is completed generally when a transaction is completed.
