Accounting Policies [Abstract]

Nature of Operations and Summary of Significant Accounting Policies

Organization and Nature of Operations

CrossFirst Bankshares, Inc. (consolidated) (the ‘‘Company’’), a Kansas corporation, was incorporated in December 2017. Prior to incorporation, the Company was registered as a limited liability company under the name CrossFirst Holdings, LLC. The Company is a bank holding company whose principal activities are the ownership and management of its wholly-owned subsidiaries, CrossFirst Bank (a subsidiary of CrossFirst Bankshares, Inc.) (the ‘‘Bank’’) and CFSA, LLC (a subsidiary of CrossFirst Bankshares, Inc.) (‘‘CFSA’’), which holds title to certain assets. In addition, CrossFirst Investments, Inc. is a wholly-owned subsidiary of CrossFirst Bank, which holds investments in marketable securities.

The Bank is primarily engaged in providing a full range of banking and financial services to individual and corporate customers through its branches in: (i) Leawood, Kansas; (ii) Wichita, Kansas; (iii) Kansas City, Missouri; (iv) Oklahoma City, Oklahoma; (v) Tulsa, Oklahoma; (vi) Dallas, Texas and (vii) Frisco, Texas (established in 2020) (‘‘Our Markets’’). The Bank is subject to competition from other financial institutions and the regulation of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities.

Basis of Presentation

Our accounting and reporting policies conform to accounting principles generally accepted in the United States (‘‘GAAP’’). The consolidated financial statements include the accounts of the Company; the Bank and its wholly-owned subsidiary, CrossFirst Investments, Inc.; and CFSA. All significant intercompany accounts and transactions were eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, valuation of deferred tax assets, other-than-temporary impairments (‘‘OTTI’’), stock based compensation, derivatives, and fair values of financial instruments.

Change in Presentation Due to Stock Split

On December 18, 2018, the Company announced a 2-for-1 stock split, effected in the form of a dividend, effective December 21, 2018. Share data and per share data were retroactively adjusted for the periods presented to reflect the change in capital structure.

Changes Affecting Comparability

For the year ended December 31, 2019, the Company broke-out several line items within the Consolidated Statements of Income that were previously consolidated. As a result, changes within the Consolidated Statements of Income in the prior periods were made to conform to the current period presentation. The break-outs: (i) better align with the break-out on the Consolidated Balance Sheets or (ii) provide additional detail about our operations. The changes had no impact on net income.

Operating Segments

An operating segment is a component of an entity that has separate financial information related to its business activities and is reviewed by the chief operating decision maker on a regular basis to allocate resources and assess performance. The Company identifies Our Markets as operating segments. Our Markets provide similar products and services using a similar process to a similar customer base. Our products and services include, but are not limited to, loans; checking and savings accounts; time deposits and credit cards. Loan products include commercial, real estate, consumer, and SBA lending. The regulatory environment is the same for Our Markets as well. The chief operating decision maker monitors the revenue and costs of Our Markets; however, operations are managed, including allocation of resources, and financial performance is evaluated on a Company-wide basis. As a result, Our Markets are aggregated into one reportable segment.

Cash Equivalents

The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. At December 31, 2019, cash equivalents consisted primarily of federal funds sold and both interest-bearing and noninterest bearing accounts with other banks. Approximately $147 million of the Company’s cash and cash equivalents were held at the Federal Reserve Bank of Kansas City at December 31, 2019. The Company is required to maintain reserve funds in cash and/or on deposit with the Federal Reserve Bank. The reserve required at December 31, 2019 was approximately $63 million. In addition, the Company is required from time to time to place cash collateral with a third party as part of its back-to-back swap agreements. At December 31, 2019, $18 million was required as cash collateral. At December 31, 2019, the Company’s cash accounts, excluding funds at the Federal Reserve Bank and funds required as cash collateral, exceeded federally insured limits by $19 million.

Securities

Debt securities for which the Company has no immediate plan to sell but which may be sold in the future, are classified as available-for-sale (‘‘AFS’’) and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of debt securities are recorded on the trade date and are determined using the specific identification method.

Equity securities for which the Company has no immediate plan to sell but which may be sold in the future are classified as available-for-sale and recorded at fair value with unrealized gains and losses included in earnings. Gains and losses on the sale of equity securities are recorded on the trade date and are determined using the specific identification method.

The Company routinely conducts periodic reviews to identify and evaluate each investment security to determine whether an OTTI has occurred. For available-for-sale securities that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections.

Loans

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balances adjusted for unearned income, charge-offs, the allowance for loan losses, any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans.

For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan.

Nonperforming Loans

Nonperforming loans are loans for which we do not accrue interest income. The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well secured and in process of collection. A credit is considered well secured if it is secured by collateral in the form of liens or pledges of real or personal property, including securities, that have a realizable value sufficient to discharge the debt (including accrued interest) in full or is secured by the guaranty of a financially responsible party. A debt is in the process of collection if collection of the debt is proceeding in due course either through legal action, including enforcement procedures, or in appropriate circumstances, through collection efforts not involving legal action which are reasonably expected to result in repayment of the debt or in its restoration to a current status. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date, if collection of principal or interest is considered doubtful.

All interest accrued but not collected for loans that are placed on nonaccrual or charged off are reversed against interest income. The interest on these loans is accounted for on the cash basis or cost recovery method, until qualifying for return to accrual. When payments are received on nonaccrual loans, payments are applied to principal unless there is a clear indication that the quality of the loan has improved to the point that it can be placed back on accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Allowance for Loan Losses

The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to income. Loan losses are charged against the allowance when management believes the loan balance is not collectible. Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of its ability to collect the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.

The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers unclassified loans and is based on historical charge-off experience and expected loss given default derived from the Company’s internal risk rating process. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data.

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on an individual loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral, if the loan is collateral dependent.

Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans.

Premises and Equipment

Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and depreciated using the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured.

The estimated useful lives for each major depreciable classification of premises and equipment are as follows:



Buildings and improvements		35-40 years
Leasehold improvements		5-15 years
Furniture and fixtures		5-7 years
Equipment		3-5 years

Long-Lived Asset Impairment

The Company evaluates the recoverability of the carrying value of long-lived assets whenever events or circumstances indicate the carrying amount may not be recoverable. If a long-lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset cost is adjusted to fair value and an impairment loss is recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value.

Restricted Equity Securities

Restricted equity securities includes investments in FHLB Topeka, Bankers’ Bank of Kansas and Bankers Bank stock. FHLB Topeka is a Federal Home Loan Bank and its stock is a required investment for institutions that are members of the Federal Home Loan System. The required investment in the common stock is based on a predetermined formula. The Bankers’ Bank of Kansas and Bankers Bank are correspondent banks located in Wichita, Kansas and Oklahoma City, Oklahoma, respectively. Each of these investments is carried at cost and evaluated for impairment.

Bank-Owned Life Insurance

The Company has purchased life insurance policies on certain key employees. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.

Foreclosed Assets Held-for-Sale

Assets acquired through, or in lieu of, loan foreclosure are held-for-sale and are initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net income or expenses from foreclosed assets.

Goodwill

Goodwill is evaluated annually for impairment or more frequently if impairment indicators are present. A qualitative assessment is performed to determine whether the existence of events or circumstances leads to a determination that it is more likely than not the fair value is less than the carrying amount, including goodwill. If, based on the evaluation, it is determined to be more likely than not that the fair value is less than the carrying value, then goodwill is tested further for impairment. If the implied fair value of goodwill is lower than its carrying amount, a goodwill impairment is indicated and goodwill is written down to its implied fair value. Subsequent increases in goodwill value are not recognized in the consolidated financial statements.

Core Deposit Intangible

The core deposit intangible represents the identified intangible asset relating to the deposit relationships acquired in past business combinations. The value of the core deposit intangible is based primarily upon the expected future benefits of earnings capacity attributable to those deposits.

Stock-Based Compensation

The Company accounts for all stock-based compensation transactions in accordance with Accounting Standard Codification (‘‘ASC’’) 718, Compensation - Stock Compensation, which requires that stock compensation transactions be recognized as compensation expense in the consolidated statement of income and other comprehensive income based on their fair values on the measurement date. The Company recognizes forfeitures as they occur. New shares are issued upon exercise of an award. The Company records permanent tax differences through the income tax provision upon vesting or exercise of a stock-based award. The various stock-based compensation plans are described more fully in Note 18.

Transfers of Financial Assets

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (i) the assets have been isolated from the Company put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership; (ii) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets; and (iii) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.

Income Taxes

The Company accounts for income taxes in accordance with income tax accounting guidance (ASC 740, Income Taxes). The income tax accounting guidance results in two components of income tax expense: (i) current; and (ii) deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability or balance sheet method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities and enacted changes in tax rates and laws are recognized in the period in which they occur.

Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term, more likely than not, means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more likely than not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more likely than not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.

The Company recognizes interest and penalties on income taxes as a component of income tax expense. The Company files consolidated income tax returns with its subsidiaries. Due to the carry forward of federal net operating losses, all prior years remain subject to examination by federal tax authorities.

Earnings Per Share

Basic earnings per share represent net income available to common stockholders divided by the weighted average number of common shares outstanding during each period. Diluted earnings per share reflect additional potential shares that would have been outstanding if dilutive potential common stock had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common stock that may be issued by the Company is determined using the treasury stock method.

Fair Values of Financial Instruments

The Company follows the applicable accounting guidance for fair value measurements and disclosures for all applicable financial and nonfinancial assets and liabilities. ASC 820, Fair Value Measurements and Disclosures (‘‘ASC 820’’), defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. The Company values financial instruments based upon quoted market prices, where available. If market prices are not available, fair value is based on pricing models that use available information including quoted prices for similar assets or liabilities in active markets, market indicators, and industry and economic events. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.

Comprehensive Income

Comprehensive income consists of net income and other comprehensive income, net of applicable income taxes. Other comprehensive income includes unrealized appreciation (depreciation) on available-for-sale securities.

Transfers between Fair Value Hierarchy Levels

Transfers in and out of Level 1 (quoted market prices), Level 2 (other significant observable inputs) and Level 3 (significant unobservable inputs) are recognized on the period ending date.

Derivative Financial Instruments

ASC 815, Derivatives and Hedging, provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (i) how and why an entity uses derivative instruments; (ii) how the entity accounts for derivative instruments and related hedged items; and (iii) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit risk related contingent features in derivative instruments.

As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge.

In accordance with the Financial Accounting Standards Board's (‘‘FASB’’) fair value measurement guidance in Accounting Standard Updated (‘‘ASU’’) 2011-04, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counter-party portfolio.

Initial Public Offering

On August 19, 2019, the Company completed its initial public offering (‘‘IPO’’) of common shares. The Company issued and sold 5,750,000 common shares at a public offering price of $14.50 per share. After deducting the underwriting discounts and offering expenses, the Company received total net proceeds of $76 million from the IPO. In addition, certain selling stockholders participated in the offering and sold an aggregate of 1,261,589 common shares at a public offering price of $14.50 per share. The Company did not receive any proceeds from the sales of shares by the selling stockholders.

On September 17, 2019, the underwriters partially exercised their option to purchase additional shares. The Company issued and sold 844,362 common shares at a public offering price of $14.50 per share. After deducting the underwriting discounts and offering expenses, the Company received total net proceeds of $11 million.

As of December 31, 2019, the Company qualified as an emerging growth company (‘‘EGC’’) under the Jumpstart Our Business Startups Act of 2012 (the ‘‘JOBS Act’’). An EGC may take advantage of reduced reporting requirements and is relieved of certain other significant requirements that are otherwise generally applicable to public companies. Amongst the reductions and reliefs, the Company elected to extend the transition period for complying with new or revised accounting standards affecting public companies. This means that the financial statements the Company files or furnishes, will not be subject to all new or revised accounting standards generally applicable to public companies for the transition period for so long as the Company remains an EGC or until the Company affirmatively and irrevocably opts out of the extended transition period under the JOBS Act.

ASU 2019-10 Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates	Effective immediately, but included here for informational purposes as it relates to the ASU listed in the ‘‘description’’ section.	Amended the mandatory effective dates for all entities related to: (i) credit losses - ASU 2016-13; (ii) goodwill - ASU 2017-04; (iii) leases - ASU 2016-02; and (iv) hedging - ASU 2017-12 The amended dates were incorporated into the “anticipated date of adoption” section for the appropriate ASU below.	No expected impact to the financial statements, but delays certain ASUs for private companies, smaller reporting companies and EGCs that elected to use the private company effective dates for new or revised accounting standards. If a company loses its EGC status during the fiscal year, the company would be required to review all ASUs as a PBE and adopt any ASU effective for PBEs as of the first day of that year.
ASU 2018-15 Intangibles-Goodwill and Other-Internal-Use Software	ASU 2018-15 will be effective for the Company on December 31, 2021. Early adoption is permitted including adoption in any interim period. The amendments will be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption.	Aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal use software.	At this time, an estimate of the impact to the Company’s financial statements is not known.
ASU 2018-13 Fair Value Measurement (Topic 820): Disclosure Framework	ASU 2018-13 will be effective for the Company on January 1, 2020. Early adoption is permitted upon issuance of this update. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this update and delay adoption of the additional disclosures until their effective date.	Improves the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information. The amendments modify certain disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement.	ASU 2018-13 is not expected to have a significant impact on the Company’s consolidated financial statements.



Standard	Anticipated Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2017-04 Intangibles-Goodwill and Other (Topic 250)-Simplifying the Test for Goodwill Impairment	ASU 2017-04 will be effective for the Company in fiscal years beginning after December 15, 2021. Early adoption is permitted for interim or annual impairment tests beginning in 2017.	Eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. An entity should perform an annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit.	ASU 2017-04 is not expected to have a significant impact on the Company’s consolidated financial statements.
ASU 2016-13 Financial Instruments-Credit Losses	Prior to year-end, the Company expected to implement the standard in 2020. Management decided additional parallel testing and further validation of the Current Expected Credit Losses (‘‘CECL’’) model will improve reliability and sustainability of the model. If we maintain our EGC status, the Company is not required to implement this standard until January 2023. The Company will monitor the progress and the requirements related to adoption.	Requires an entity to utilize a new impairment model known as the current expected credit loss model to estimate its lifetime expected credit loss and record an allowance that, when deducted from amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset.	The Company has established a committee of individuals from applicable departments to oversee the implementation process. The Company implemented a third-party software solution and completed the software implementation phase of the transition. The software implementation phase included data capture and portfolio segmentation amongst other items. The Company has completed an initial parallel run using 2019 data and completed a second parallel during the fourth quarter of 2019. The Company is currently evaluating the internal control changes that will be necessary to transition to the third-party platform. At this time, an estimate of the impact cannot be established as the Company continues to evaluate the inputs into the model. The actual impact could be significantly affected by the composition, characteristics, and quality of the underlying loan portfolio at the time of adoption.
ASU 2016-02 Leases (Topic 842)	The Company expects to implement this standard in 2021 if EGC status is maintained. If the Company loses its EGC status in 2020, the Company would be required to implement the ASU as of the beginning of 2020.	Requires lessees and lessors to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The update requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach with the option to elect certain practical expedients. The update will also increase disclosures around leases, including qualitative and specific quantitative measures.	The Company expects to apply the update as of the beginning of the period of adoption and the Company does not plan to restate comparative periods. The Company expects to elect certain optional practical expedients. The Company gathered all potential lease and embedded lease agreements during 2019 and is evaluating the applicability and impact to the financial statements. The Company’s current operating leases relate primarily to three branch locations, as well as a future lease obligation mentioned in the subsequent event note. Based on these current leases, the Company anticipates recognizing a lease liability and related right-to-use asset on its balance sheet, with an immaterial impact to its income statement compared to the current lease accounting model. However, the ultimate impact of the standard will depend on the Company's lease portfolio as of the adoption date.

Accounting Guidance Adopted During Fiscal Year 2019, 2018, and 2017

The Company implemented the following ASUs during 2019:



Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2018-07 - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting	January 2019 Early adoption	Expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees, excluding share-based payments used to effectively provide: (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments include: (i) grants are measured at grant-date fair value of the equity instruments; (ii) equity-classified nonemployee share-based payment awards are measured at the grant date; (iii) performance based awards are measured based on the probability of satisfying the performance conditions and (iv) in general, non-employee share-based payment awards will continue to be subject to the requirements of ASC 718 unless modified after the good has been delivered, the service has been rendered, any other conditions necessary to earn the right to benefit from the instrument have been satisfied, and the nonemployee is no longer providing goods or services.	The Company had 216,960 stock-based awards to non-employees as of the implementation date, including 116,960 performance-based restricted stock units. The adoption of the ASU allowed the Company to: (i) set the fair market value of the non-employee awards as of the adoption date; and (ii) start to expense the performance-based restricted stock units based on the probability of satisfying the performance conditions. Adoption of ASU 2018-07 required the Company to make a one time transfer of $2 million from retained earnings to additional paid in capital. In addition, the Company recorded a $306 thousand deferred tax asset that was offset with retained earnings to account for the tax impact. The Company will record forfeitures as they occur and base fair market values on the expected term, like the Company’s accounting for employee-based awards.
ASU 2016-01 - Financial Instruments-Overall (Subtopic 825-10)	January 2019	Required equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of practicability exceptions in determining the fair value of loans.	The Company transferred $69 thousand from accumulated other comprehensive loss to retained earnings in January 2019. There was no impact to the income statement on the adoption date.
ASU 2014-09 - Revenue from Contracts with Customers	January 2019	Amended guidance related to revenue from contracts with customers. 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. Replaced nearly all existing revenue recognition guidance, including industry specific guidance, established a new control based revenue recognition model, changed the basis for deciding when revenue is recognized over time or at a point in time, provided new and more detailed guidance on specific topics and expands and improves disclosures about revenue.	The accounting update did not materially impact the financial statements or recognition of revenues. The update did not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, which comprises a significant portion of the Company’s revenue stream. In addition, the Company’s noninterest income is generated by customer transactions or through the passage of time and as a result the pattern or timing of income recognition was not impacted.

The Company implemented the following ASUs during 2018:



Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2018-02 - Income Statement Reporting Comprehensive Income (Topic 220)	February 2018, retrospectively applied to 2017	Allowed a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act.	A reclassification totaling $1 million related to items recognized in accumulated other comprehensive income.
ASU 2017-09 Compensation -Stock Compensation (Topic 718): Scope of Modification Accounting	January 2018	Provides guidance about which changes to terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. An entity should account for the effects of a modification unless all the following are met: (i) The fair value does not change as a result of the modification or the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification; (ii) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified and (iii) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified.	The adoption of ASU 2017-09 did not have a significant impact on the Company’s consolidated financial statements.

The Company implemented the following ASUs during 2017:



Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2017-08 Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities	December 2017	Shortened the amortization period for certain callable debt securities held at a premium. The amendments require the premium to be amortized to the earliest call date.	The adoption of ASU 2017-08 did not have a significant impact on the Company’s consolidated financial statements.
ASU 2016-09 Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting	December 2017	Simplified several aspects of the accounting for share-based payment transactions. The simplification includes: (i) requiring all excess tax benefits and tax deficiencies to be recognized as income tax expense or benefit in the income statement; (ii) excess tax benefits are classified as an operating activity; (iii) allowing an entity wide accounting policy election to estimate the number of awards that are expected to vest or account for forfeitures when they occur; (iv) permitting the withholding tax threshold to qualify for equity classification to the maximum statutory tax rates in the applicable jurisdictions; and (v) clarifying cash paid by an employer when directly withholding shares to tax- withholding purposes should be classified as a financing activity.	The Company early adopted ASU 2016-09. The Company elected to account for forfeitures when they occur. The impact to the 2017 consolidated financial statements was approximately $70 thousand in income tax benefits.

Gross Unrealized Losses

Certain investments in debt securities are reported in the consolidated financial statements at an amount less than their historical cost. Total fair value of these investments at December 31, 2019 and 2018, was $108 million and $367 million, which was approximately 15% and 56%, respectively, of the Company’s available-for-sale debt investment portfolio.

The unrealized losses on the Company’s investments in state and political subdivisions were caused by interest rate changes and adjustments in credit ratings. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. The unrealized losses on the Company’s investments in collateralized mortgage-backed securities and obligations were caused by interest rate changes and market assumptions about prepayment speeds.

The Company expects to recover the amortized cost basis over the term of the securities, excluding a previously disclosed impaired security discussed further below. Because the Company does not intend to sell the investments and it is not more likely than not the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be OTTI at December 31, 2019.

Based on evaluation of available evidence, including recent changes in market interest rates, credit rating information and information obtained from regulatory filings, management believes the declines in fair value for these securities are temporary.

The following table shows available-for-sale debt securities gross unrealized losses, the number of securities that are in an unrealized loss position, and fair value of the Company’s investments with unrealized losses that are not deemed to be OTTI, aggregated by investment class and length of time that individual securities have been in a continuous unrealized loss position at December 31, 2019 and 2018:

Other-Than-Temporary Impairment

Upon acquisition of a security, the Company decides whether it is within the scope of the accounting guidance for beneficial interests in securitized financial assets or will be evaluated for impairment under the accounting guidance for investments in debt and equity securities.

The accounting guidance for beneficial interests in securitized financial assets provides incremental impairment guidance for a subset of the debt securities within the scope of the guidance for investments in debt and equity securities. For securities where the security is a beneficial interest in securitized financial assets, the Company uses the beneficial interests in securitized financial asset impairment model. For securities where the security is not a beneficial interest in securitized financial assets, the Company uses the debt and equity securities impairment model.

The Company routinely conducts periodic reviews to identify and evaluate each investment security to determine whether an OTTI has occurred. Economic models are used to determine whether an OTTI has occurred on these securities. The Company recorded no OTTI losses on AFS securities in 2019, 2018 or 2017.

During 2016, a $2 million OTTI loss consisted of a credit loss on one municipal security. No portion of the loss was recognized in other comprehensive income. At December 31, 2019, the Company held this security at a market value of $0.

Equity Securities

Equity securities consist of Community Reinvestment Act mutual funds. The fair value of the equity securities was $2 million and $2 million at December 31, 2019 and December 31, 2018, respectively. Prior to January 1, 2019, equity securities were stated at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of tax. A net unrealized loss of $69 thousand had been recognized in accumulated other comprehensive income as of December 31, 2018. On January 1, 2019, the unrealized loss was reclassified out of accumulated other comprehensive income and into retained earnings with subsequent changes in fair value being recognized in other noninterest income. The following is a summary of the recorded fair value and the unrealized and realized gains and losses recognized in net income on available-for-sale equity securities:

The Company consolidated the consumer installment and equity line of credit categories of loans. The new category is called consumer loans. The Company determined that the use of funds, source of repayment, and underlying credit risks were similar enough to consolidate the two categories. All historical financial information was adjusted to account for this consolidation. The change did not impact the consolidated balance sheets, consolidated statements of income or cash flow statement.

The following tables summarize the activity in the allowance for loan losses by portfolio segment and disaggregated based on the Company’s impairment methodology. The allocation in one portfolio segment does not preclude its availability to absorb losses in other segments:

Credit Risk Profile

The Company analyzes its loan portfolio based on an internal rating category (grades 1 - 8), portfolio segment and payment activity. These categories are utilized to develop the associated allowance for loan losses. A description of the loan grades and segments follows:

Loan Grades

Loan grades are numbered 1 through 8. Grades 1 through 4 are considered satisfactory grades. The grade of 5, (Special Mention), represents loans of lower quality and are considered criticized. The grades of 6, (Substandard) and 7, (Doubtful), refer to assets that are classified. The use and application of these grades by the Company will be uniform and shall conform to the Company’s policy.

Excellent (1): Credits in this category represent minimum loss exposure to the Company and the probability of a serious, rapid deterioration is extremely small. Loans are generally secured by certificates of deposit, savings accounts or U.S. Government securities.

Superior (2): Borrowers for credits in this category generally maintain a high degree of liquidity and sound financial condition. In addition, they generally reflect a long history of earnings, high quality collateral and availability of alternative funding sources under all economic circumstances.

Good (3): Borrowers for credits in this category generally maintain good liquidity and financial condition. Debt is programmed and timely repayment is expected. Alternative funding sources are generally available through other financial institutions.

Watch (4): While credits in this category are currently protected, sales trends may be flat or declining, gross margins may be below average but operating profits appear to be satisfactory to meet debt service. Most ratios compare favorably with industry norms and Company policies.

Special Mention (5): Borrowers for credits in this category generally exhibit adverse trends in their operations or an imbalanced position in their balance sheet that has not reached a point where repayment is jeopardized. Credits with this rating are currently protected but, if left uncorrected, the potential weaknesses may result in deterioration of the repayment prospects for the credit or in the Company’s credit or lien position at some future date. These credits are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.

Substandard (6): Credits which exhibit a well-defined weakness or weaknesses that jeopardize repayment. Credits so rated are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged. A distinct possibility exists that the Company will sustain some loss if deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified substandard.

Doubtful (7): Credits which exhibit all the weaknesses inherent in a substandard credit with the added characteristic that these weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently existing facts, conditions and values. Because of reasonably specific pending factors that may work to the advantage and strengthening of the assets, classification as a loss is deferred until its more exact status may be determined. Loans should be placed on nonaccrual. Pending factors include proposed merger, acquisition or liquidation procedures, capital injection, perfecting liens on additional collateral and refinancing plans.

Loss (8): Credits which are considered uncollectible or of such little value that their continuance as a bankable asset is not warranted. There may be salvage value, but it is not practical or desirable to defer writing off the asset. The Company should not attempt long term recoveries while the asset is booked.

Loan Portfolio Segments

Risk characteristics applicable to each segment of the loan portfolio are described as follows:

Commercial: Includes loans to commercial customers for use in financing working capital needs, accounts receivable and inventory financing, equipment purchases and expansions. Repayment is primarily from the cash flow of a borrower’s principal business operation. Generally, short-term loans have maturities ranging from six months to two years and term loans have maturities ranging from five to seven years. Credit risk is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations.

Energy: Includes loans to oil and natural gas customers for use in financing working capital needs, exploration and production activities, and acquisitions. The loans in this category are repaid primarily from the conversion of crude oil and natural gas to cash. Credit risk is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations.

Commercial Real Estate: Loans typically involve larger principal amounts, and repayment of these loans is generally dependent on the successful operations of the property securing the loan or the business conducted on the property securing the loan. These are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Credit risk may be impacted by the creditworthiness of a borrower, property values and the local economies in the borrower’s market areas.

Construction and Land Development: Loans are usually based upon estimates of costs and estimated value of the completed project and include independent appraisal reviews and a financial analysis of the developers and property owners. Sources of repayment include permanent loans, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are higher risk than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, general economic conditions and the availability of long-term financing. Credit risk may be impacted by the creditworthiness of a borrower, property values and the local economies in the borrower’s market areas.

Residential Real Estate: Loans are generally secured by owner occupied 1-4 family residences. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans can be impacted by economic conditions within or outside the borrower’s market areas that might impact either property values or a borrower’s personal income. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over many borrowers.

Consumer: The loan portfolio consists of revolving lines of credit and various term loans such as automobile loans and loans for other personal purposes. Repayment is primarily dependent on the personal income and credit rating of the borrowers. Credit risk is driven by consumer economic factors (such as unemployment and general economic conditions in the Company’s market area) and the creditworthiness of a borrower.

Impaired Loans

A loan is considered impaired, in accordance with the impairment accounting guidance (ASC 310-10-35-16), when based on current information and events, it is probable the Company will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include nonperforming loans but also include loans modified in troubled debt restructurings (‘‘TDR’’) where concessions have been granted to borrowers experiencing financial difficulties. The intent of concessions is to maximize collection.

The following tables present impaired loans for the periods ended December 31, 2019 and December 31, 2018:

Nonaccrual Loans

Nonperforming loans are loans for which the Company does not record interest income. The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well secured and in process of collection. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date, if collection of principal or interest is considered doubtful.

The following table presents the Company’s nonaccrual loans at December 31, 2019 and 2018:

Troubled Debt Restructurings

Restructured loans are those extended to borrowers who are experiencing financial difficulty and who have been granted a concession. The modification of terms typically includes the extension of maturity, reduction or deferment of monthly payment, or reduction of the stated interest rate. A TDR may also exist if the borrower transfers to the Bank: (i) receivables for third parties; (ii) real estate; (iii) other assets or (iv) an equity position in the borrower to fully or partially satisfy a loan or the issuance or other granting of an equity position to the Bank to fully or partially satisfy a debt unless the equity position is granted pursuant to existing terms for converting the debt into an equity position.

Once an obligation has been restructured because of such credit problems, it continues to be considered restructured until: (i) the obligation is paid in full or (ii) the borrower is in compliance with its modified terms for at least 12 consecutive months, the loan has a market rate, and the borrower could obtain similar terms from another bank. When a loan undergoes a TDR, the determination of whether the loan would remain on accrual status depends on several factors including: (i) the loan was on accrual status prior to the restructuring; (ii) the borrower demonstrated performance under the previous terms and (iii) the Bank’s credit evaluation shows the borrower’s capacity to continue to perform under the restructured terms.

Loans identified as TDRs are evaluated for impairment using the present value of the expected cash flows or the estimated fair value of the collateral if the loan is collateral dependent. The fair value is determined, when possible, by an appraisal of the property less estimated costs related to liquidation of the collateral. The appraisal amount may also be adjusted for current market conditions. Adjustments to reflect the present value of the expected cash flows or the estimated fair value of collateral dependent loans are a component in determining an appropriate allowance, and as such, may result in increases or decreases to the provision for loan losses in current and future earnings.

The table below presents loans restructured during the years ended December 31, 2019 and 2018, including the post-modification outstanding balance and the type of concession made:

Total troubled debt restructurings	$	34,766	$	6,742

As of December 31, 2019 and 2018, the Company had $934 thousand and $0, respectively, in commitments to borrowers whose terms were modified in troubled debt restructurings. As of December 31, 2019, the modifications related to the troubled debt restructurings above did not impact the allowance for loan losses because the loans were previously impaired and evaluated on an individual basis or enough collateral was obtained to provide an additional commitment. The restructured loans had a total specific valuation allowance of $18 million and $2 million as of December 31, 2019 and December 31, 2018, respectively.

For the year ended December 31, 2019 and 2018, the TDRs outstanding resulted in charge-offs of $5 million and $1 million and recoveries of $0 and $439 thousand, respectively. One commercial TDR modified within the previous 12 months defaulted during 2019 with an outstanding balance of $28 million as of December 31, 2019. During 2018, one commercial TDR modified within the past 12 months defaulted with an outstanding balance of $55 thousand.

The balance of restructured loans is provided below as of December 31, 2019 and December 31, 2018. In addition, the balance of those loans that are in default at any time during the past 12 months at December 31, 2019 and December 31, 2018 is provided below:

During 2018, the Company purchased office space in Leawood, Kansas to establish a new corporate headquarters. The total cost was approximately $51 million, including the $29 million purchase price for the building. In relation to the purchase, the Company was granted several state tax incentives that will reduce the Company’s future state tax payments.

Assets Held for Sale

The Company placed two support buildings and the related furniture, fixtures and equipment on the market in 2017 as employees moved to the new corporate headquarters. One support building was purchased in 2012 and the other in 2014; both were remodeled. Due to the short time frame between purchase and sale, the Company was unable to recover the remodeling costs.

The Company recorded a $2 million impairment charge in 2017 for these buildings based on available market value information as of December 31, 2017. One building was sold during the third quarter of 2018 and resulted in an additional $171 thousand loss. The remaining building was sold in the second quarter of 2019. The purchase price of the remaining building was approximately $3 million, and resulted in an additional impairment of $424 thousand.

Derivatives and Hedging Activities

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging Activities

Derivatives and Hedging ActivitiesDerivatives not designated as hedges are not speculative and result from a service the Company provides to clients. The Company executes interest rate swaps with customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting derivatives that the Company executes with a third-party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate derivatives associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings.

During the third quarter of 2019, the Company changed an input associated with the fair market value related to derivatives not designated as hedges. The model utilized to calculate the nonperformance risk, also known as the credit valuation adjustment (‘‘CVA’’), was adjusted from a default methodology to an internal review process by the Company. Management believes this change better aligns with the Company’s credit methodology and underwriting standards.

As a result of the change in methodology, the Company recorded an adjustment to increase swap fee income, net by approximately $800 thousand, related to swaps closed as of June 30, 2019. If no defaults occur for derivatives not designated as hedges, the change in methodology will lower future swap fee income, net by the same amount.

As of December 31, 2019 and 2018, the Company had the following outstanding derivatives that were not designated as hedges in qualifying hedging relationships:



	December 31, 2019			December 31, 2018

	(Dollars in thousands)
Back-to-back swaps	56	$	380,050	20	$	77,709

The effect of the Company’s derivative financial instruments gain or loss are reported on the statements of cash flows within other assets and other liabilities.

The net presentation above can be reconciled to the tabular disclosure of fair value.

As of December 31, 2019, the Company had minimum collateral posting thresholds with certain of its derivative counterparties and had posted collateral of $18 million. If the Company had breached any of these provisions at December 31, 2019, it could have been required to settle its obligations under the agreements at their termination value of $10 million.

The Company has agreements with certain of its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well capitalized institution, then the Company could be considered in default. As of December 31, 2019, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $10 million. The Company was considered well capitalized as of December 31, 2019.

Foreclosed assets primarily consisted of industrial facilities, commercial use facilities and raw land. Upon acquisition, these assets are recorded at fair value less estimated selling costs at the date of foreclosure, establishing a new cost basis. They are subsequently carried at the lower of cost or fair value less estimated selling costs.

Interest-bearing Time Deposits

Interest-bearing time deposits in denominations of $250,000 or more were $692 million and $540 million as of December 31, 2019 and 2018, respectively.

The Company acquires brokered deposits in the normal course of business. At December 31, 2019 and 2018, brokered deposits of approximately $392 million and $343 million, respectively, were included in the Company’s time deposit balance. Due to the passage of the Economic Growth, Regulatory Relief, and Consumer Protection Act in 2018, reciprocal deposits at December 31, 2019 and 2018, including the Company’s The Certificate of Deposit Account Registry Service (‘‘CDARS’’), are treated as core deposits instead of brokered deposits and are not included in the above amounts.

The Company is a member of CDARS which effectively allows depositors to receive FDIC insurance on amounts greater than the FDIC insurance limit, which is currently $250,000. CDARS allows institutions to break large deposits into smaller amounts and place them in a network of other CDARS institutions to ensure full FDIC insurance is gained on the entire deposit. CDARS totaled approximately $42 million and $48 million as of December 31, 2019 and 2018, respectively.

At December 31, 2019, the scheduled maturities for time deposits were as follows:

⁽¹⁾ Securities sold under agreements to repurchase consist of obligations of the Bank to other parties that are payable on demand and generally have one day maturities. The obligations are collateralized by securities of U.S. government sponsored enterprises and mortgage-backed securities and such collateral is held by a third-party custodian. The year-to-date average daily balance was $44 million and $77 million for December 31, 2019 and 2018, respectively. The securities, mortgage-backed government sponsored residential securities, pledged for customer repurchase agreements were $37 million and $103 million at December 31, 2019 and 2018, respectively.

⁽²⁾ Federal funds purchased include short-term funds that are borrowed from another bank. The Bank is part of a third-party service that allows us to borrow amounts from another bank if the bank has approved us for credit. Federal funds purchased generally have one day maturities.

During 2019, the Company received a $2 million gross state tax credit that will offset certain state income taxes. As a result, the Company recorded a $2 million tax benefit, offset by $362 thousand in federal tax expense during the first quarter of 2019. A $1 million deferred tax asset was recorded as result of the state tax credit in 2019. During 2018, the Company received a $3 million state tax credit that will offset certain state income taxes. The Company had a $3 million deferred tax asset as of December 31, 2019 due to the state tax credits. The deferred tax asset will decrease as the Company produces certain state taxable income and expires on December 31, 2034.

On December 22, 2017, the United States enacted tax reform legislation through the Tax Cuts and Jobs Act, which significantly changed the existing U.S. tax laws, including a reduction in the corporate tax rate from 35% to 21%. As a result of enactment of the legislation, the Company incurred additional one time income tax expense of $3 million during the fourth quarter of fiscal 2017, primarily related to the remeasurement of certain deferred tax assets and liabilities.

Because ASC 740 requires the effect of income tax law changes on deferred taxes to be recognized as a component of income tax expense related to continuing operations, the net adjustment to deferred taxes detailed above included a net benefit totaling $1 million related to items recognized in accumulated other comprehensive income. In February 2018, the FASB issued ASU 2018-02 that allows the tax effects stranded in accumulated other comprehensive income to be reclassified to retained earnings rather than income tax benefit or expense. The Company early adopted this ASU, making it effective at December 31, 2017. At December 31, 2017, the stranded amount was transferred from accumulated other comprehensive income to retained earnings.

The tax effects of temporary differences related to deferred taxes shown on the consolidated balance sheets are presented below:

The Company has approximately $2 million of federal net operating loss carry-forwards, which expire after 2028. The net operating loss is subject to annual usage limitations of $180 thousand per year, but may include unused amounts from prior years. The Company fully expects to utilize the entire net operating loss carry-forwards before they expire.

The Company had $0 of alternative minimum tax credits remaining at the end of December 31, 2019. The 2017 Tax Cuts and Jobs Act repealed the corporate alternative minimum tax (‘‘AMT’’) for tax years beginning after December 31, 2017. Taxpayers may claim a refund on AMT credit carryovers. The maximum annual refund is fifty percent of the Company’s remaining AMT credits in tax years 2018, 2019, and 2020. In 2021, a refund on all remaining credits will be received. The Company used the remainder of the AMT credits in 2019.

State Tax Exam

During the fourth quarter of 2019, the Company received notice of a state tax audit for tax years ended December 31, 2017 and 2018. It is the opinion of management the disposition or ultimate resolution of any findings will not have a material adverse effect on the consolidated financial position, result of operations and cash flows of the Company.

Regulatory Matters

12 Months Ended

Dec. 31, 2019

Regulatory Matters

The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance-sheet items as calculated under U.S. GAAP, regulatory reporting requirements and regulatory capital standards. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Furthermore, the Company’s regulators could require adjustments to regulatory capital not reflected in these consolidated financial statements.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total and tier I capital (as defined) to risk-weighted assets (as defined), common equity tier I capital (as defined) to risk-weighted assets (as defined), and of tier I capital (as defined) to average assets (as defined). Management believes, as of December 31, 2019, the Company and the Bank meet all capital adequacy requirements to which they are subject.

As of December 31, 2019, the most recent notification from the applicable regulatory agencies categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum total risk-based, tier I risk-based, common equity tier I risk-based and tier I leverage ratios as set forth in the table below.

The above minimum capital requirements include the capital conservation buffer required to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers. The capital conservation buffer was phased in from 0.0% for 2015 to 2.5% as of January 1, 2019. The capital conservation buffer was 2.5% at December 31, 2019. The net unrealized gain or loss on AFS securities is not included in computing regulatory capital.

The three federal banking regulatory agencies jointly published final rules (the Basel III Capital Rules) establishing a new comprehensive capital framework for U.S. banking organizations. The rules implement the Basel Committee’s December 2010 framework known as “Basel III” for strengthening international capital standards as well as certain provisions of the Dodd-Frank Wall Street Consumer Protection Act (‘‘Dodd-Frank Act’’). These rules substantially revise the risk-based capital requirements applicable to bank holding companies and depository institutions, compared to the current U.S. risk-based capital rules. The Basel III Capital rules define the components of capital and address other issues affecting the numerator in banking institutions regulatory capital ratios. These rules also address risk weights and other issues affecting the denominator in banking institutions regulatory capital ratios and replace the existing risks weighting approach with a more risk sensitive approach. The Basel III Capital Rules were effective January 1, 2015 subject to a four year phase-in period.

The Basel III Capital Rules, among other things: (i) introduce a new capital measure called Common Equity Tier 1; (ii) specify that Tier 1 capital consist of CET1 and Additional Tier 1 Capital instruments meeting specified requirements; (iii) define CET1 narrowly by requiring that most deductions/adjustments to regulatory capital measures be made to CET1 and not to the other components of capital; and (iv) expand the scope of the deductions and adjustments as compared to existing regulations.

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

The Company adopted ASU 2014-09, ‘‘Revenue from Contracts with Customers (Topic 606)’’ and its related amendments as of January 1, 2019 using the modified retrospective approach. The implementation had no material impact on the measurement or recognition of revenue of either current or prior periods.

The categories are selected based on the nature, amount, timing, and uncertainty of revenue and cash flows. The following presents descriptions of revenue categories within the scope of ASU 2014-09 (ASC 606):

Service charges and fees (rebates) on customer accounts - This segment consists of monthly fees for the services rendered on customer deposit accounts, including maintenance charges, overdraft fees, and processing fees. The monthly fee structures are typically based on type of account, volume, and activity. The customer is typically billed monthly and pays the bill from their deposit account. The Company satisfies the performance obligation related to providing depository accounts monthly as transactions are processed and deposit service charge revenue is recorded.

ATM and credit card interchange income - This segment consists of fees charged for use of the Company’s ATMs, as well as, an interchange fee with credit card and debit card service providers. ATM fees and interchange fees are based on the number of transactions, as well as, the underlying agreements. Customers are typically billed monthly. The Company satisfies the performance obligation related to ATM and interchange fees monthly as transactions are processed and revenue is recorded.

International fees - This segment consists of fees earned from foreign exchange transactions and preparation of international documentation. International fees are based on underlying agreements that describe the Company’s performance obligation and the related fee. Customers are typically billed and cash is received once the service or transaction is complete. The Company satisfies the performance obligation related to international fees monthly as transactions are processed and revenue is recorded.

Other fees - This segment consists of numerous, smaller fees such as wire transfer fees, check cashing fees, and check printing fees. Other fees are typically billed to customers on a monthly basis. Performance obligations for other fees are satisfied at the time that the service is rendered.

The following table disaggregates the noninterest income subject to ASU 2014-09 by category:



	For the Year Ended December 31,
	2019
	(Dollars in thousands)
Noninterest income subject to ASU 2014-09
Service charges and fees (rebates) on customer accounts	$	604
ATM and credit card interchange income	1,785
International fees	716

Total noninterest income	$	8,715

The Company had no material contract assets or contract liabilities for the twelve months ended December 31, 2019.

Equity Compensation

12 Months Ended

Dec. 31, 2019

Share-based Payment Arrangement [Abstract]

Equity Compensation

Equity CompensationThe Company issues stock-based compensation in the form of non-vested restricted stock and stock appreciation rights under the 2018 Omnibus Equity Incentive Plan (‘‘Omnibus Plan’’). In addition, the Company has an Employee Stock Purchase Plan (‘‘ESPP’’) that was indefinitely suspended effective April 1, 2019. The Omnibus Plan will expire on the tenth anniversary of its effective date. The aggregate number of shares authorized for future issuance under the Omnibus Plan is 2,295,856 shares as of December 31, 2019. The Company will issue new common shares upon exercise or vesting of stock-based awards.

During 2018, the Company announced a 2-for-1 stock split effected in the form of a dividend. The stock split was effective on December 21, 2018. Except as described herein, stock-based awards were retroactively adjusted for all periods presented to reflect the change in capital structure.

During 2018, awards issued under the Stock Settled Appreciation Right (‘‘SSAR’’) Plan, Equity Incentive Plan, Employee Equity Incentive Plan and New Market Founder Plan were assumed under the Omnibus Plan as agreed upon with participants, impacting all participants who agreed to the assumption. The awards are called ‘‘Legacy Awards.’’ Material terms and conditions of Legacy Awards remain unchanged; therefore, no modification to their fair market value was required. Going forward, all awards will be issued under the Omnibus Plan.

During 2018, several events, including the ones mentioned above, impacted equity-based compensation. A table showing the events and the impact to equity-based compensation is provided at the end of Note 18.

The table below summarizes stock-based compensation for the years ended December 31, 2019, 2018, and 2017:



	For the Year Ended December 31,
	2019		2018		2017
	(Dollars in thousands)
Stock appreciation rights	$	1,243	$	1,457	$	769
Performance-based stock awards	271		578		1,390
Restricted stock awards	3,174		2,404		88
Employee stock purchase plan	36		165		128
Total stock-based compensation	$	4,724	$	4,604	$	2,375

Stock Settled Appreciation Rights

SSARs are granted based on the fair market value of the Company’s common stock. SSARs typically vest in equal amounts over a seven-year period, commencing on the first anniversary of the effective date of grant and have fifteen-year contractual terms for Legacy Awards and ten-year contractual terms for all other SSARs. Legacy Awards include retirement eligibility upon the participant’s 65th birthday, five years of participation, and after one year holding the grant. The exercise of a SSAR entitles the participant to the excess of the exercise price over the grant price for each SSAR. Exercise price is based on the fair market value of the Company’s common shares.

During 2018, the Company issued 100,000 SSARs with a strike price of $28.50 to a nonemployee. The SSARs vest in equal amounts over a five-year period, commencing on the first anniversary of the effective date of grant and have a five-year contractual term. The Company determined that the award did not require substantive service, which required the award to be fully expensed at the grant date. Because the award is to a nonemployee, the fair market value for this award was adjusted quarterly until the Company adopted ASU 2018-07 in the first quarter of 2019, which set the fair market value for this award. Additional information on ASU 2018-07 can be found in Note 1. The SSAR was not adjusted with respect to the 2-for-1 stock split in accordance with the underlying agreements with the nonemployee and the applicable plan, which did not provide for adjustment.

During 2018, the Company accelerated the vesting of 107,482 SSARs in accordance with the Chairman Emeritus Agreement. The acceleration resulted in $430 thousand in additional expense due to modification accounting. Both the award to the nonemployee and modification to existing SSARs are included in the tables below.

During 2018, 240,000 SSARs were granted that vest in equal amounts over a three-year period, commencing on the first anniversary of the effective date of grant and have fifteen-year contractual terms.

The calculated value of each share award is estimated at the grant date using a Black-Scholes option valuation model. Expected volatility is primarily based on an internal model that calculates the historical volatility of the Company’s stock since the IPO and several peer group banks’ weekly average stock prices before the IPO over the expected term. The expected term of stock granted represents the period of time that shares are expected to be outstanding. The risk-free rate for periods within the contractual life of the share award is based on the U.S. Treasury yield curve.

For the expected term, the Company uses the simplified method described in SAB Topic 14.D.2. This method uses an expected term based on the midpoint between the vesting date and the end of the contractual term. This method is used for the majority of SSARs, because the Company does not have a significant pool of SSARs that have been exercised. For some SSARs that are granted to participants who will be retirement eligible during the term of the award, a separate analysis is performed that focuses more on expected retirement date.

The following table provides the range of assumptions used in the Black-Scholes valuation model, the weighted average grant date fair value, and information related to SSARs exercised for the followings years, as well as, the remaining compensation cost to be recognized and period over which the amount will be recognized as of December 31, 2019:



	For the Year Ended December 31,
	2019⁽¹⁾	2018	2017
	(Dollars in thousands, except per share data)
Assumptions:
Expected volatility	24.63% - 33.63%	25.69% - 42.99%	28.40% - 40.94%
Expected dividends	0.00%	0.00%	0.00%

Aggregate intrinsic value of SSARs exercised	$493	$2,214	$165
Total fair value of SSARs vested during the year	$1,171	$1,710	$959
Unrecognized compensation information:
Unrecognized compensation cost	$2,904	$3,730	$3,068
Period remaining (in years)	3.9	3.9	4.8
⁽¹⁾The Black-Scholes inputs include a revaluation of a nonemployee SSAR upon adoption of ASU 2018-07, as well as, SSARs granted during the period.

A summary of SSAR activity during and as of December 31, 2019 is presented below:



	Stock Settled Appreciation Rights
	Units		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term
Outstanding, January 1, 2019	1,736,574		$	9.94	10.28

Exercisable, December 31, 2019	854,562		$	8.29	8.19

Performance-Based Stock Awards (‘‘PBSAs’’)

The Company awards PBSAs to key officers of the Company. The stock settled awards are typically granted annually as determined by the Compensation Committee. The performance based shares typically cliff-vest at the end of three years based on attainment of certain performance metrics developed by the Compensation Committee. The ultimate number of shares issuable under each performance award is the product of the award target and the award payout percentage given the level of achievement. The award payout percentages by level of achievement range between 0% of target and 150% of target.

During 2016, the Company awarded PBSAs to New Market Founders. A New Market Founder is a nonemployee, adviser chosen in a selected market to facilitate expansion of banking relationships. During 2016, 110,900 PBSAs were granted and cliff-vest on December 31, 2021. No compensation expense was recognized as part of this plan during 2018 and 2017. The Company adopted ASU 2018-07 in the first quarter of 2019, which set the fair market value for this award. The Company determined that no substantial service existed for this award, resulting in a cumulative effect adjustment of approximately $2 million to retained earnings. Additional information on ASU 2018-07 can be found in Note 1. Changes to the expected or actual award payout percentages will be immediately expensed going forward.

Issuance of the above New Market Founder PBSAs is based upon four equally weighted market measures: total assets, total loans, return on assets and classified assets to capital as of December 31, 2021. The ultimate number of shares issuable under each performance award is the product of the award target and the award payout percentage given the level of achievement. The award payout percentages by level of achievement range between 0% of target to 150% of target. Achievement between 50% of target (“threshold”) and 150% (“stretch”) will result in an award payout percentage determined based on straight-line interpolation between the percentiles. A maximum of 248,841 units could be issued.

The following table summarizes the status of and changes in the performance-based awards:



	Performance-Based Awards
	Number of Shares	Weighted Average Grant Date Fair Value
Nonvested, January 1, 2019	159,384	$	9.00
Granted⁽¹⁾	32,864	14.16
Vested	—	0.00
Forfeited	—	0.00
Nonvested, December 31, 2019	192,248	$	9.88
⁽¹⁾Includes 6,060 Legacy PBSAs regranted under the Omnibus Plan upon agreement with a New Market Founder. The fair market value of common stock at the regrant date was $15.50. No modifications to the grants occurred resulting in no increase to the fair market value.The original Legacy PBSA had a weighted average grant date fair value of $8.25.

Unrecognized stock-based compensation expense related to the performance grants issued through December 31, 2019 was $495 thousand and is expected to be recognized over 2.1 years.

Restricted Stock Units (‘‘RSUs’’) and Restricted Stock Awards(‘‘RSAs’’)

The Company issues RSUs and RSAs to provide additional incentives to key officers, employees, and nonemployee directors. Awards are typically granted annually as determined by the Compensation Committee. The service based RSUs typically cliff-vest at the end of three years for Legacy Awards and vest in equal amounts over three years for all other RSUs. The service based RSAs typically cliff-vest after one year.

During 2018, 60,000 Legacy RSUs were granted with a grant date fair market value of $14.25 per unit and vests in equal amounts over a three year period, commencing on the first anniversary of the effective date of grant.

During 2018, the Company accelerated the vesting of 74,280 RSUs in accordance with the Chairman Emeritus Agreement. The acceleration resulted in $694 thousand to be immediately expensed instead of over the initial expected service period.

The following table summarizes the status of and changes in the RSUs and RSAs:



	Restricted Stock Units and Awards
	Number of Shares	Weighted Average Grant Date Fair Value
Nonvested, January 1, 2019	333,774	$	14.47
Granted	170,394	15.50
Vested	(152,486)	13.68
Forfeited	(10,902)	14.00
Nonvested, December 31, 2019	340,780	$	15.35

Unrecognized stock-based compensation expense related to restricted stock grants issued through December 31, 2019 was $3 million and is expected to be recognized over 1.7 years.

Employee Stock Purchase Plan

The Company has an ESPP whereby employees are eligible for the plan when they have met certain requirements concerning period of credited service and minimum hours worked. During the year ended December 31, 2019, 45,302 common shares were purchased on behalf of the employees under the ESPP.

The calculated value of each unit award is estimated at the start of the offering period using a Black-Scholes option valuation model that used the assumptions noted in the following table:



	For the Year Ended December 31,
	2019	2018	2017
Assumptions:
Expected volatility	7.60%	7.60%	13.80%
Expected dividends	0.00%	0.00%	0.00%
Expected term (in years)	1	1	1
Risk-free rate	2.09%	2.09%	1.03%

On January 24, 2019, the Company indefinitely suspended the ESPP effective April 1, 2019 There was no impact to the financial statements as a result of the suspension.

In January 2018, the Company modified the Equity Incentive Plan to allow the Compensation Committee to award performance-based awards or service-based awards. The Compensation Committee modified awards granted in 2016 and 2017 from performance-based to service-based awards. The modification resulted in a $1 million increase in expense that will be recognized over the remaining service period. A total of 25 participants were impacted by this modification. During 2018, $989 thousand was recognized, including $61 thousand in forfeiture credits. The remaining $216 thousand was recognized in 2019.

In May 2018, the Company’s former Chief Executive Officer became the Company’s Chairman Emeritus. As part of this transition, restricted stock units issued under the Equity Incentive Plan in 2016, 2017, and 2018 were fully vested. The modification resulted in $694 thousand of additional expense. In addition, all SSARs awarded under the Stock Appreciation Rights Plan were considered fully-vested. This modification resulted in $430 thousand of additional expense. All awards were converted to common stock and 101,178 common shares were issued. The Chairman Emeritus Agreement also granted 100,000 SSARs that will vest equally over five years.

In October 2018, the Omnibus Plan was approved. The Omnibus Plan allows for several types of grants including: (i) stock options; (ii) SARs; (iii) RSAs; (iv) RSUs; and (v) PBSAs. Awards issued under the previous plans were assumed under the Omnibus Plan, as agreed upon with participants, impacting all participants who agreed to the assumption. Material terms and conditions of Legacy Awards remain unchanged; therefore, no modification to their fair market value was required.

Leases [Abstract]

Operating Leases

During 2017, the Bank took possession of office space in Dallas, Texas through an operating lease agreement. The non-cancellable lease has a term of 147-months from the commencement date with escalating rental payments. The agreement includes an option for early termination after year seven, but requires an additional payment equal to one month of gross rent for each remaining year, repayment of all unamortized incentives, and $30 thousand. In addition, the lease provides an option to be extended for three renewal periods of five years each. As an incentive for the lease, the Bank received $2 million in tenant improvement allowances and abated rent. In accordance with ASC 840, the Company is amortizing this benefit through occupancy expense over the expected life of the lease.

During 2017, the Bank commenced a lease for office space in Leawood, Kansas. The noncancellable lease expired on June 30, 2018 with straight-line rental payments. During 2017, CrossFirst Bank entered into an agreement to purchase the office space for $29 million upon the expiration of the operating lease. During 2018, the Company purchased the office space per the agreement.

The Company has various noncancellable operating leases for office space in its respective markets. Rent expense for these leases for the periods presented was:

Fair Value Disclosures [Abstract]

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a hierarchy of three levels of inputs that may be used to measure fair value:



Level 1		Quoted prices in active markets for identical assets or liabilities
Level 2		Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3		Unobservable inputs supported by little or no market activity and significant to the fair value of the assets or liabilities.

Recurring Measurements

The following tables present the fair value measurements of assets and liabilities recognized in the accompanying consolidated balance sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall at December 31, 2019 and 2018:

Following is a description of the valuation methodologies and inputs used for assets and liabilities measured at fair value on a recurring basis and recognized in the Company’s accompanying consolidated balance sheets, as well as the general classification of such instruments pursuant to the valuation hierarchy.

Available-for-Sale Securities

Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using quoted prices of securities with similar characteristics or independent asset pricing services and pricing models, the inputs of which are market-based or independently sourced market parameters, including, but not limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections and cash flows. Such securities are classified in Level 2 of the valuation hierarchy.

Derivatives

Fair value of the interest rate swaps is obtained from independent pricing services based on quoted market prices for similar derivative contracts.

Nonrecurring Measurements

The following tables present the fair value measurement of assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at:



			December 31, 2019
			Fair Value Measurements Using
	Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Unobservable Inputs (Level 3)

Assets held-for-sale	3,444		—		3,444		—

Following is a description of the valuation methodologies and inputs used for assets measured at fair value on a nonrecurring basis and recognized in the accompanying consolidated balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below.

Collateral Dependent Impaired Loans, Net of Allowance for Loan and Lease Losses (‘‘ALLL’’)

The estimated fair value of collateral-dependent impaired loans is based on the appraised fair value of the collateral, less estimated cost to sell. Collateral dependent impaired loans are classified within Level 3 of the fair value hierarchy. The Company considers the appraisal or evaluation as the starting point for determining fair value and then considers other factors and events in the environment that may affect the fair value. Appraisals of the collateral underlying collateral dependent loans are obtained when the loan is determined to be collateral-dependent and subsequently as deemed necessary by the Chief Credit Officer.

Appraisals are reviewed for accuracy and consistency by the Chief Credit Officer. Appraisers are selected from the list of approved appraisers maintained by management. The appraised values are reduced by discounts to consider lack of marketability and estimated cost to sell if repayment or satisfaction of the loan is dependent on the sale of the collateral. These discounts and estimates are developed by the Chief Credit Officer by comparison to historical results.

Assets Held-for-Sale

The estimated fair value of assets held-for-sale is based on the appraised fair value of the collateral, less estimated cost to sell.

Unobservable (Level 3) Inputs

The following tables present quantitative information about unobservable inputs used in nonrecurring Level 3 fair value measurements at December 31, 2019 and 2018:



	As of December 31, 2019

Total	$	1,546,495	$	1,416,656

Commitments to Originate Loans

Commitments to originate loans 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 a portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case by case basis. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate and residential real estate.

Standby Letters of Credit

Standby letters of credit are irrevocable conditional commitments issued by the Company to guarantee the performance of a customer to a third-party. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under nonfinancial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. Fees for letters of credit are initially recorded by the Company as deferred revenue and are included in earnings at the termination of the respective agreements.

Should the Company be obligated to perform under the standby letters of credit, the Company may seek recourse from the customer for reimbursement of amounts paid.

Lines of Credit

Lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Lines of credit generally have fixed expiration dates. Since a portion of the line may expire without being drawn upon, the total unused lines do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case by case basis. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the counter-party.

Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, commercial real estate and residential real estate. Management uses the same credit policies in granting lines of credit as it does for on balance sheet instruments.

Future Lease Commitment

During 2017, the Company entered into a lease agreement for future office space in Kansas City, Missouri. The 15 year lease will begin upon substantial completion of the building or the date the Company takes possession of the premises for business purposes and includes four, five year renewal terms.

The future minimum lease payments for the current lease commitment are as follows:



Year	Minimum Lease Payments
	(Dollars in thousands)
1	$	1,303
2	1,312
3	1,321
4	1,331
5	1,341

In association with the Kansas City, Missouri lease, the lessor will provide the Company with a construction allowance of approximately $1 million.

Recent Accounting Pronouncements and Accounting Guidance Adopted

Recent Accounting Pronouncements

The following ASUs represent changes to current accounting guidance that will be adopted in future years:



Standard	Anticipated Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2019-10 Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates	Effective immediately, but included here for informational purposes as it relates to the ASU listed in the ‘‘description’’ section.	Amended the mandatory effective dates for all entities related to: (i) credit losses - ASU 2016-13; (ii) goodwill - ASU 2017-04; (iii) leases - ASU 2016-02; and (iv) hedging - ASU 2017-12 The amended dates were incorporated into the “anticipated date of adoption” section for the appropriate ASU below.	No expected impact to the financial statements, but delays certain ASUs for private companies, smaller reporting companies and EGCs that elected to use the private company effective dates for new or revised accounting standards. If a company loses its EGC status during the fiscal year, the company would be required to review all ASUs as a PBE and adopt any ASU effective for PBEs as of the first day of that year.
ASU 2018-15 Intangibles-Goodwill and Other-Internal-Use Software	ASU 2018-15 will be effective for the Company on December 31, 2021. Early adoption is permitted including adoption in any interim period. The amendments will be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption.	Aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal use software.	At this time, an estimate of the impact to the Company’s financial statements is not known.
ASU 2018-13 Fair Value Measurement (Topic 820): Disclosure Framework	ASU 2018-13 will be effective for the Company on January 1, 2020. Early adoption is permitted upon issuance of this update. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this update and delay adoption of the additional disclosures until their effective date.	Improves the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information. The amendments modify certain disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement.	ASU 2018-13 is not expected to have a significant impact on the Company’s consolidated financial statements.



Standard	Anticipated Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2017-04 Intangibles-Goodwill and Other (Topic 250)-Simplifying the Test for Goodwill Impairment	ASU 2017-04 will be effective for the Company in fiscal years beginning after December 15, 2021. Early adoption is permitted for interim or annual impairment tests beginning in 2017.	Eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. An entity should perform an annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit.	ASU 2017-04 is not expected to have a significant impact on the Company’s consolidated financial statements.
ASU 2016-13 Financial Instruments-Credit Losses	Prior to year-end, the Company expected to implement the standard in 2020. Management decided additional parallel testing and further validation of the Current Expected Credit Losses (‘‘CECL’’) model will improve reliability and sustainability of the model. If we maintain our EGC status, the Company is not required to implement this standard until January 2023. The Company will monitor the progress and the requirements related to adoption.	Requires an entity to utilize a new impairment model known as the current expected credit loss model to estimate its lifetime expected credit loss and record an allowance that, when deducted from amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset.	The Company has established a committee of individuals from applicable departments to oversee the implementation process. The Company implemented a third-party software solution and completed the software implementation phase of the transition. The software implementation phase included data capture and portfolio segmentation amongst other items. The Company has completed an initial parallel run using 2019 data and completed a second parallel during the fourth quarter of 2019. The Company is currently evaluating the internal control changes that will be necessary to transition to the third-party platform. At this time, an estimate of the impact cannot be established as the Company continues to evaluate the inputs into the model. The actual impact could be significantly affected by the composition, characteristics, and quality of the underlying loan portfolio at the time of adoption.
ASU 2016-02 Leases (Topic 842)	The Company expects to implement this standard in 2021 if EGC status is maintained. If the Company loses its EGC status in 2020, the Company would be required to implement the ASU as of the beginning of 2020.	Requires lessees and lessors to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The update requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach with the option to elect certain practical expedients. The update will also increase disclosures around leases, including qualitative and specific quantitative measures.	The Company expects to apply the update as of the beginning of the period of adoption and the Company does not plan to restate comparative periods. The Company expects to elect certain optional practical expedients. The Company gathered all potential lease and embedded lease agreements during 2019 and is evaluating the applicability and impact to the financial statements. The Company’s current operating leases relate primarily to three branch locations, as well as a future lease obligation mentioned in the subsequent event note. Based on these current leases, the Company anticipates recognizing a lease liability and related right-to-use asset on its balance sheet, with an immaterial impact to its income statement compared to the current lease accounting model. However, the ultimate impact of the standard will depend on the Company's lease portfolio as of the adoption date.

Accounting Guidance Adopted During Fiscal Year 2019, 2018, and 2017

The Company implemented the following ASUs during 2019:



Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2018-07 - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting	January 2019 Early adoption	Expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees, excluding share-based payments used to effectively provide: (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments include: (i) grants are measured at grant-date fair value of the equity instruments; (ii) equity-classified nonemployee share-based payment awards are measured at the grant date; (iii) performance based awards are measured based on the probability of satisfying the performance conditions and (iv) in general, non-employee share-based payment awards will continue to be subject to the requirements of ASC 718 unless modified after the good has been delivered, the service has been rendered, any other conditions necessary to earn the right to benefit from the instrument have been satisfied, and the nonemployee is no longer providing goods or services.	The Company had 216,960 stock-based awards to non-employees as of the implementation date, including 116,960 performance-based restricted stock units. The adoption of the ASU allowed the Company to: (i) set the fair market value of the non-employee awards as of the adoption date; and (ii) start to expense the performance-based restricted stock units based on the probability of satisfying the performance conditions. Adoption of ASU 2018-07 required the Company to make a one time transfer of $2 million from retained earnings to additional paid in capital. In addition, the Company recorded a $306 thousand deferred tax asset that was offset with retained earnings to account for the tax impact. The Company will record forfeitures as they occur and base fair market values on the expected term, like the Company’s accounting for employee-based awards.
ASU 2016-01 - Financial Instruments-Overall (Subtopic 825-10)	January 2019	Required equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of practicability exceptions in determining the fair value of loans.	The Company transferred $69 thousand from accumulated other comprehensive loss to retained earnings in January 2019. There was no impact to the income statement on the adoption date.
ASU 2014-09 - Revenue from Contracts with Customers	January 2019	Amended guidance related to revenue from contracts with customers. 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. Replaced nearly all existing revenue recognition guidance, including industry specific guidance, established a new control based revenue recognition model, changed the basis for deciding when revenue is recognized over time or at a point in time, provided new and more detailed guidance on specific topics and expands and improves disclosures about revenue.	The accounting update did not materially impact the financial statements or recognition of revenues. The update did not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, which comprises a significant portion of the Company’s revenue stream. In addition, the Company’s noninterest income is generated by customer transactions or through the passage of time and as a result the pattern or timing of income recognition was not impacted.

The Company implemented the following ASUs during 2018:



Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2018-02 - Income Statement Reporting Comprehensive Income (Topic 220)	February 2018, retrospectively applied to 2017	Allowed a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act.	A reclassification totaling $1 million related to items recognized in accumulated other comprehensive income.
ASU 2017-09 Compensation -Stock Compensation (Topic 718): Scope of Modification Accounting	January 2018	Provides guidance about which changes to terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. An entity should account for the effects of a modification unless all the following are met: (i) The fair value does not change as a result of the modification or the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification; (ii) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified and (iii) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified.	The adoption of ASU 2017-09 did not have a significant impact on the Company’s consolidated financial statements.

The Company implemented the following ASUs during 2017:



Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2017-08 Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities	December 2017	Shortened the amortization period for certain callable debt securities held at a premium. The amendments require the premium to be amortized to the earliest call date.	The adoption of ASU 2017-08 did not have a significant impact on the Company’s consolidated financial statements.
ASU 2016-09 Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting	December 2017	Simplified several aspects of the accounting for share-based payment transactions. The simplification includes: (i) requiring all excess tax benefits and tax deficiencies to be recognized as income tax expense or benefit in the income statement; (ii) excess tax benefits are classified as an operating activity; (iii) allowing an entity wide accounting policy election to estimate the number of awards that are expected to vest or account for forfeitures when they occur; (iv) permitting the withholding tax threshold to qualify for equity classification to the maximum statutory tax rates in the applicable jurisdictions; and (v) clarifying cash paid by an employer when directly withholding shares to tax- withholding purposes should be classified as a financing activity.	The Company early adopted ASU 2016-09. The Company elected to account for forfeitures when they occur. The impact to the 2017 consolidated financial statements was approximately $70 thousand in income tax benefits.

ASU 2018-07 - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting	January 2019 Early adoption	Expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees, excluding share-based payments used to effectively provide: (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments include: (i) grants are measured at grant-date fair value of the equity instruments; (ii) equity-classified nonemployee share-based payment awards are measured at the grant date; (iii) performance based awards are measured based on the probability of satisfying the performance conditions and (iv) in general, non-employee share-based payment awards will continue to be subject to the requirements of ASC 718 unless modified after the good has been delivered, the service has been rendered, any other conditions necessary to earn the right to benefit from the instrument have been satisfied, and the nonemployee is no longer providing goods or services.	The Company had 216,960 stock-based awards to non-employees as of the implementation date, including 116,960 performance-based restricted stock units. The adoption of the ASU allowed the Company to: (i) set the fair market value of the non-employee awards as of the adoption date; and (ii) start to expense the performance-based restricted stock units based on the probability of satisfying the performance conditions. Adoption of ASU 2018-07 required the Company to make a one time transfer of $2 million from retained earnings to additional paid in capital. In addition, the Company recorded a $306 thousand deferred tax asset that was offset with retained earnings to account for the tax impact. The Company will record forfeitures as they occur and base fair market values on the expected term, like the Company’s accounting for employee-based awards.
ASU 2016-01 - Financial Instruments-Overall (Subtopic 825-10)	January 2019	Required equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of practicability exceptions in determining the fair value of loans.	The Company transferred $69 thousand from accumulated other comprehensive loss to retained earnings in January 2019. There was no impact to the income statement on the adoption date.
ASU 2014-09 - Revenue from Contracts with Customers	January 2019	Amended guidance related to revenue from contracts with customers. 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. Replaced nearly all existing revenue recognition guidance, including industry specific guidance, established a new control based revenue recognition model, changed the basis for deciding when revenue is recognized over time or at a point in time, provided new and more detailed guidance on specific topics and expands and improves disclosures about revenue.	The accounting update did not materially impact the financial statements or recognition of revenues. The update did not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, which comprises a significant portion of the Company’s revenue stream. In addition, the Company’s noninterest income is generated by customer transactions or through the passage of time and as a result the pattern or timing of income recognition was not impacted.

The Company implemented the following ASUs during 2018:



Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2018-02 - Income Statement Reporting Comprehensive Income (Topic 220)	February 2018, retrospectively applied to 2017	Allowed a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act.	A reclassification totaling $1 million related to items recognized in accumulated other comprehensive income.
ASU 2017-09 Compensation -Stock Compensation (Topic 718): Scope of Modification Accounting	January 2018	Provides guidance about which changes to terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. An entity should account for the effects of a modification unless all the following are met: (i) The fair value does not change as a result of the modification or the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification; (ii) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified and (iii) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified.	The adoption of ASU 2017-09 did not have a significant impact on the Company’s consolidated financial statements.

The Company implemented the following ASUs during 2017:



Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2017-08 Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities	December 2017	Shortened the amortization period for certain callable debt securities held at a premium. The amendments require the premium to be amortized to the earliest call date.	The adoption of ASU 2017-08 did not have a significant impact on the Company’s consolidated financial statements.
ASU 2016-09 Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting	December 2017	Simplified several aspects of the accounting for share-based payment transactions. The simplification includes: (i) requiring all excess tax benefits and tax deficiencies to be recognized as income tax expense or benefit in the income statement; (ii) excess tax benefits are classified as an operating activity; (iii) allowing an entity wide accounting policy election to estimate the number of awards that are expected to vest or account for forfeitures when they occur; (iv) permitting the withholding tax threshold to qualify for equity classification to the maximum statutory tax rates in the applicable jurisdictions; and (v) clarifying cash paid by an employer when directly withholding shares to tax- withholding purposes should be classified as a financing activity.	The Company early adopted ASU 2016-09. The Company elected to account for forfeitures when they occur. The impact to the 2017 consolidated financial statements was approximately $70 thousand in income tax benefits.
