Organization, Operations And Basis Of Presentation [Abstract]
Organization, Operations And Basis Of Presentation	GUARANTY BANCORP AND SUBSIDIARIES Notes to Unaudited Condensed Consolidated Financial Statements  (1) Organization, Operations and Basis of Presentation  Guaranty Bancorp is a bank holding company registered under the Bank Holding Company Act of 1956, as amended, and headquartered in Colorado.  The Company’s principal business is to serve as a holding company for its bank subsidiary, Guaranty Bank and Trust Company, referred to as the “Bank”.  References to “Company,” “us,” “we,” and “our” refer to Guaranty Bancorp on a consolidated basis. References to “Guaranty Bancorp” or to the “holding company” refer to the parent company on a stand-alone basis.  The Bank is a full-service community bank offering an array of banking products and services to the communities it serves along the Front Range of Colorado including: accepting time and demand deposits and originating commercial loans, commercial and residential real estate loans, Small Business Administration (“SBA”) guaranteed loans and consumer loans. The Bank, together with its wholly owned subsidiary Private Capital Management, LLC (“PCM”), provides wealth management services, including private banking, investment management and trust services. On April 3, 2017, Cherry Hills Investment Advisors, Inc., a previous wholly owned subsidiary of the Bank, was consolidated into PCM. Substantially all of the Bank’s loans are secured by specific items of collateral, including business assets, commercial and residential real estate, which include land or improved land, and consumer assets. Commercial loans are expected to be repaid from cash flow from the operations of businesses that have taken out the loans. There are no significant concentrations of loans to any one industry or customer. On September 8, 2016, the Company completed the acquisition of Home State Bancorp (“Home State”), based in Loveland, Colorado, in exchange for a combination of Company stock and cash. The transaction enhanced the Company’s balance sheet liquidity and supports the Company’s objective of serving the banking needs of northern Colorado business and consumer customers.  (a) Basis of Presentation  The accounting and reporting policies of the Company conform to generally accepted accounting principles in the United States of America. All material intercompany balances and transactions have been eliminated in consolidation. The Company’s financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of its financial position and results of operations for the periods presented. All such adjustments are of a normal and recurring nature. Subsequent events have been evaluated through the date of financial statement issuance.  Certain information and note disclosures normally included in consolidated financial statements, prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States of America, have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The interim operating results presented in these financial statements are not necessarily indicative of operating results for the full year. For further information, refer to the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.  (b) Business Combinations  The Company accounts for acquisitions of businesses using the acquisition method of accounting. Under the acquisition method, assets acquired and liabilities assumed are recorded at their estimated fair value upon the date of acquisition. Management utilizes various valuation techniques including discounted cash flow analyses to determine the fair values of assets acquired and liabilities assumed. Any excess of purchase price over amounts allocated to the acquired assets, including identifiable intangible assets, and liabilities assumed is recorded as goodwill.  (c) Use of Estimates  The preparation of the consolidated financial statements, in conformity with U.S. GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the consolidated balance sheets and income and expense for the periods presented. Actual results could differ significantly from those estimates.  (d) Loans and Loan Commitments  The Company extends commercial, real estate and consumer loans to customers. A substantial portion of the loan portfolio consists of commercial and real estate loans throughout the Front Range of Colorado. The ability of the Company’s borrowers to honor their loan contracts is generally dependent upon the real estate and general economic conditions prevailing in Colorado, among other factors.  Purchased loans, that on the date of acquisition reflected evidence of credit deterioration since origination and for which collection of all contractually required payments was not probable were designated as purchased credit impaired or “PCI” loans. In the September 8, 2016 Home State transaction, the Company designated $2,108,000 of loans as PCI. As of June 30, 2017, $1,290,000 in PCI loans remained in the Company’s loan portfolio. Loans not designated as PCI (“Non-PCI” loans) comprise the significant majority of the Company’s loan portfolio and consist of internally originated loans in addition to acquired loans. Acquired Non-PCI loans were designated as such as of the date of acquisition for one of or both of the following reasons: (1) management considered the collection of all contractually required payments probable, and (2) the loan demonstrated no evidence of credit deterioration since origination.  Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, are reported at their outstanding unpaid principal balances, adjusted for charge-offs, the allowance for loan losses, acquisition-related discounts and any deferred fees or costs. Acquired loans are recorded upon acquisition at fair value, with no associated allowance for loan loss. However, if subsequent to acquisition, the credit quality of an acquired loan deteriorates, an allowance may be required. Accounting for loans is performed consistently across all portfolio segments and classes.  A portfolio segment is defined in accounting guidance as the level at which an entity develops and documents a systematic methodology to determine its allowance for loan losses. A class is defined in accounting guidance as a group of loans having similar initial measurement attributes, risk characteristics and methods for monitoring and assessing risk.  Interest income is accrued on the unpaid principal balance of the Company’s loans. Loan origination fees, net of direct origination costs, are deferred and recognized as an adjustment to the related loan yield using the effective interest method without anticipating prepayments. Purchase discount or premium on acquired Non-PCI loans is recognized as an adjustment to interest income over the contractual life of such loans using the effective interest method, or taken into income when the related loans are paid off or sold. With respect to PCI loans, the “accretable yield”, calculated as the excess of undiscounted expected cash flows at acquisition over the fair value at acquisition, is accreted into income over the term of the loan assuming the amount and timing of cash flows are reasonably estimable.  The accrual of interest on loans is discontinued (and the loan is put on nonaccrual status) at the time the loan is 90 days past due unless the loan is well secured and in process of collection. The time at which a loan enters past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off prior to the date on which they would otherwise enter past due status if collection of principal or interest is considered doubtful. The interest on a nonaccrual loan is accounted for using the cost-recovery or cash-basis method until the loan qualifies for a return to the accrual-basis method. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero, with payments received being applied first to the principal balance of the loan. Under the cash-basis method, interest income is recognized when the payment is received in cash. A loan is returned to accrual status after the delinquent borrower’s financial condition has improved, when all the principal and interest amounts contractually due are brought current, and when the likelihood of the borrower making future timely payments is reasonably assured.  Financial instruments include off ‑balance sheet credit instruments, such as commitments to make loans and commercial letters of credit issued to meet customer financing needs. The face amount of each item represents the Company’s total exposure to loss with respect to the item before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.  (e) Allowance for Loan Losses and Allowance for Unfunded Commitments  The allowance for loan losses, or “the allowance”, is a valuation allowance for probable incurred loan losses and is reported as a reduction of outstanding loan balances.  Management evaluates the amount of the allowance on a regular basis based upon its periodic review of the collectability of the Company’s loans. Factors affecting the collectability of the loans include historical loss, the nature and volume of the loan portfolio, adverse situations that may affect borrowers’ ability to repay, estimated value of any underlying collateral, prevailing economic conditions and historical loss experience. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. Management maintains the allowance at a level that it deems appropriate to adequately provide for probable incurred losses in the loan portfolio and other extensions of credit. The Company’s methodology for estimating the allowance is consistent across all portfolio segments and classes of loans.  Loans deemed to be uncollectable are charged-off and deducted from the allowance. The Company’s loan portfolio primarily consists of non-homogeneous commercial and real estate loans where charge-offs are considered on a loan-by-loan basis based on the facts and circumstances, including management’s evaluation of collateral values in comparison to book values on collateral-dependent loans. Charge-offs on smaller balance unsecured homogenous type loans, such as overdrafts and ready reserves are recognized by the time the loan in question is 90 days past due. The provision for loan losses and recoveries on loans previously charged-off are added to the allowance.  The allowance consists of both specific and general components. The specific component relates to loans that are individually classified as impaired. All loans are subject to individual impairment evaluation should the pertinent facts and circumstances suggest that such evaluation is necessary. Factors considered by management in determining impairment include the loan’s payment status and the probability of collecting scheduled principal and interest payments when they become due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. 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 original underlying loan agreement. 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. If a loan is impaired, a portion, if any, of the allowance is allocated so that the loan is reported at the present value of estimated future cash flows using the loan’s original contractual rate or at the fair value of collateral, less estimated selling costs, if repayment is expected solely from collateral. Troubled debt restructurings (“TDRs”) are separately identified for impairment disclosures. If a TDR is considered to be a collateral-dependent loan, impairment of the loan is measured using the fair value of the collateral, less estimated selling costs. Likewise, if a TDR is not collateral-dependent, impairment is measured using the present value of estimated future cash flows using the loan’s effective rate at inception. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with its accounting policy for the allowance.  The general component of the allowance covers all other loans not specifically identified as impaired and is determined by calculating losses recognized by portfolio segment during the current credit cycle and adjusted based on management’s evaluation of various qualitative factors. In performing this calculation, loans are aggregated into one of three portfolio segments: Real Estate, Consumer and Commercial & Other. An assessment of risks impacting loans in each of these portfolio segments is performed and qualitative adjustment factors, which will adjust the historical loss rate, are estimated. These qualitative adjustment factors consider current conditions relative to conditions present throughout the current credit cycle in the following areas: credit quality, loan class concentration levels, economic conditions, loan growth dynamics and organizational conditions. The historical loss experience is adjusted for management’s estimate of the impact of these factors based on the risks present for each portfolio segment.  The Company recognizes a liability in relation to unfunded commitments that is intended to represent the estimated future losses on commitments. In calculating the amount of this liability, management considers the amount of the Company’s off-balance sheet commitments, estimated utilization factors and loan specific risk factors. The Company’s liability for unfunded commitments is calculated quarterly and the liability is included under “other liabilities” in the consolidated balance sheet.  (f) Goodwill and Other Intangible Assets  Goodwill was recorded in the Home State transaction and represents the excess of the purchase price over the fair value of acquired tangible assets, identifiable intangible assets and liabilities. Goodwill is assessed at least annually for impairment and any such impairment is recognized in the period identified.  Intangible assets acquired in a business combination are amortized over their estimated useful lives to their estimated residual values and evaluated for impairment whenever changes in circumstances indicate that such an evaluation is necessary.  Core deposit intangible assets (“CDI assets”) are recognized at the time of their acquisition based on valuations prepared by independent third parties or other estimates of fair value. In preparing such valuations, management considers variables such as deposit servicing costs, attrition rates and market discount rates. CDI assets are amortized to expense over their useful lives, ranging from 10 years to 15 years.  Customer relationship intangible assets are recognized at the time of their acquisition based upon management’s estimate of their fair value. In preparing their valuation, management considers variables such as growth in existing customer base, attrition rates and market discount rates. The c ustomer relationship intangible assets are amortized to expense over their estimated useful life, which has been estimated to be 10 years. The Company has recognized three customer relationship intangible assets as a result of the acquisitions of PCM on July 31, 2012, Cherry Hills Investment Advisers Inc. on July 16, 2014 and Home State on September 8, 2016.  (g) Derivative Instruments  The Company records all derivatives on its consolidated balance sheets at fair value. At the inception of a derivative contract, the Company designates the derivative as one of three types based on the Company’s intentions and belief as to the derivative’s likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). To date, the Company has entered into cash flow hedges and stand-alone derivative agreements but has not entered into any fair value hedges. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction impacts earnings. Any portion of the cash flow hedge not deemed highly effective in hedging the changes in expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings as noninterest income.  The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the derivative contract. This documentation includes linking cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the hedge is highly effective in offsetting changes in cash flows of the hedged items.  (h) Stock Incentive Plan  The Company’s Amended and Restated 2005 Stock Incentive Plan (the “Incentive Plan”) provided for the grant of equity-based awards representing up to a total of 1,700,000 shares of voting common stock to key employees, nonemployee directors, consultants and prospective employees. The Incentive Plan expired by its terms on April 4, 2015. At the Company’s annual meeting of stockholders on May 5, 2015, the Company’s stockholders approved the Guaranty Bancorp 2015 Long-Term Incentive Plan (the “2015 Plan”), which had been previously approved by the Company’s Board of Directors. The 2015 Plan provides for the grant of stock options, stock awards, stock unit awards, performance stock awards, stock appreciation rights and other equity-based awards representing up to a total of 935,000 shares of voting common stock to key employees, nonemployee directors, consultants and prospective employees. All awards issued under the Incentive Plan will remain outstanding in accordance with their terms despite the expiration of the Incentive Plan; however, any awards granted subsequent to the expiration of the Incentive Plan have been, and will continue to be, issued under the 2015 Plan.  As of June 30, 2017, the Company had granted stock awards under both the Incentive Plan and the 2015 Plan. The Company recognizes stock compensation expense for services received in a share-based payment transaction over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. The compensation cost of employee and director services received in exchange for stock awards is based on the grant date fair value of the award, as determined by quoted market prices. Stock compensation expense is recognized using an estimated forfeiture rate, adjusted as necessary to reflect actual forfeitures. The Company has issued stock awards that vest based on the passage of time over service periods of one to five years (in some cases vesting in annual installments, in other cases cliff vesting at the end of the service period) and other stock awards that vest contingent upon the satisfaction of certain performance conditions. The last date on which outstanding performance stock awards may vest is February 15, 2020. Compensation cost related to the performance stock awards is recognized based on an evaluation of expected financial performance in comparison to established criteria . Should expectations of the Company’s future financial performance change, expense to be recognized in future periods could be impacted.  (i) Stock Repurchase Plan  On February 7, 2017, the Company’s Board of Directors authorized the extension of the expiration date of the Company’s share repurchase program originally announced in April 2014. Due to previous extensions the program was scheduled to expire on April 2, 2017, however, this most recent extension extends the expiration date of the repurchase program through April 2, 2018. Pursuant to the program, the Company may repurchase up to 1,000,000 shares of its voting common stock, par value $0.001 per share. As of the date of this filing, the Company had not repurchased any shares under the program.  (j) Income Taxes  Income tax expense is the total of the current year’s income tax payable or refundable and the increase or decrease in deferred tax assets and liabilities. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period of the enactment date.  Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that the Company will not realize some portion of or the entire deferred tax asset. At June 30, 2017 and December 31, 2016, the Company had a net deferred tax asset of $2,990,000 and $4,846,000 , respectively, which includes the deferred tax asset (liability) associated with the net unrealized loss (gain) on securities and interest rate swaps. After analyzing the composition of, and changes in, the deferred tax assets and liabilities and considering the Company’s forecasted future taxable income and various tax planning strategies, including the intent to hold the securities available for sale that were in a loss position until maturity, management determined that as of June 30, 2017, it was “more likely than not” that the net deferred tax asset would be fully realized. As a result, there was no valuation allowance with respect to the Company’s deferred tax asset as of June 30, 2017 or December 31, 2016.  The Company and the Bank are subject to U.S. federal income tax, State of Colorado income tax and income tax in other states. Generally, the Company is no longer subject to examination by Federal taxing authorities for years before 2013 and is no longer subject to examination by the State of Colorado for years before 2012. The Company recognizes interest related to income tax matters as interest expense and penalties related to income tax matters as other noninterest expense. At June 30, 2017 and December 31, 2016, the Company did no t have any amounts accrued for interest or penalties.  (k) Earnings per Common Share  Basic earnings per common share represents the earnings allocable to common stockholders divided by the weighted average number of common shares outstanding during the period. Dilutive common shares that may be issued by the Company represent unvested stock awards subject to a service or performance condition.  Earnings per common share have been computed based on the following calculation of weighted average shares outstanding:      Three Months Ended June 30, Six Months Ended June 30,  2017 2016 2017 2016   Average common shares outstanding 27,913,082 21,242,520 27,890,446 21,213,706  Effect of dilutive unvested stock grants (1) 182,789 135,829 230,300 224,075  Average shares outstanding for calculated  diluted earnings per common share 28,095,871 21,378,349 28,120,746 21,437,781  _____________    (1) Unvested stock grants representing 487,994 shares at June 30 , 2017 had a dilutive impact of 182,789 and 230,300 shares in the diluted earnings per share calculation for the three and six months ended June 30 , 2017, respectively. Unvested stock grants representing 554,591 shares at June 30 , 2016 had a dilutive impact of 135,829 and 224,075 shares in the diluted earnings per share calculation for the three and six months ended June 30 , 2016, respectively.   (l) Recently Issued Accounting Standards  Adoption of New Accounting Standards:  In March 2016, the FASB issued accounting standards update 2016-09 Compensation-Stock Compensation. The purpose of the update was to simplify the accounting for share-based payment transactions, including the income tax consequences of such transactions. Under the provisions of the update, the income tax consequences of excess tax benefits and deficiencies should be recognized in income tax expense in the reporting period in which the awards vest. Previously, excess tax benefits or deficiencies impacted stockholder’s equity directly to the extent there was a cumulative excess tax benefit. In the event that a tax deficiency had occurred during the reporting period and a cumulative excess tax benefit did not exist, the tax deficiency was recognized in income tax expense under previous GAAP. The update also provides that entities may continue to estimate forfeitures in accounting for stock-based compensation or recognize them as they occur. The provisions of this update become effective for interim and annual periods beginning after December 15, 2016, however early adoption was permitted beginning in 2016. The Company adopted the provisions of the update in the fourth quarter 2016. During the first six months of 2017, $560,000 of excess tax benefits related to restricted stock vestings reduced income tax expense. Comparatively, excess tax benefits of $321,000 were retroactively recognized in the first six months of 2016, upon adoption in the fourth quarter 2016.  Recently Issued but not yet Effective Accounting Standards:  In May 2014, the FASB issued accounting standards update 2014-09 Revenue from Contracts with Customers. The main provisions of the update require the identification of performance obligations within a contract and require the recognition of revenue based on a stand-alone allocation of contract revenue to each performance obligation. Performance obligations may be satisfied and revenue recognized over a period of time if: (i) the customer simultaneously receives and consumes the benefits provided by the entity’s performance as the entity performs, or (ii) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or (iii) the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. For public business entities, the amendments of this update are effective beginning with interim and annual reporting periods beginning after December 15, 2017. Interest income earned on financial instruments is outside of the scope of the update, and as a result the impact of the update is limited to certain components of noninterest income. Management does not expect the requirements of this update to have a material impact on the Company’s financial position, results of operations or cash flows and expects that the most significant impact will be the disaggregated disclosure of certain components of noninterest income. While certain implementation issues relevant to our industry are still pending resolution, such as the applicability to interchange revenues, our preliminary conclusions reached as to the application of this new guidance are not expected to be significantly affected. We will continue to evaluate any impact, including changes to related disclosures, as additional guidance is issued and as our internal assessment progresses. In January 2016, the FASB released accounting standards update 2016-01 Recognition and Measurement of Financial Assets and Liabilities. The main provisions of the update are to eliminate the available for sale classification of accounting for equity securities and to adjust the fair value disclosures for financial instruments carried at amortized costs such that the disclosed fair values represent an exit price as opposed to an entry price. The provisions of this update will require that equity securities be carried at fair market value on the balance sheet and any periodic changes in value will be adjustments to the income statement. A practical expedient is provided for equity securities without a readily determinable fair value, such that these securities can be carried at cost less any impairment. The provisions of this update become effective for interim and annual periods beginning after December 15, 2017. The disclosure of fair value of the loan portfolio will be impacted as the fair value will be calculated using an exit price. Management does not expect the requirements of this update to have a material impact on the Company’s financial position, results of operations or cash flows.  In February 2016, the FASB issued accounting standards update 2016-02 Leases. The update requires all leases, with the exception of short-term leases that have contractual terms of no greater than one year, to be recorded on the balance sheet. Under the provisions of the update, leases classified as operating will be reflected on the balance sheet with the recognition of both a right-of-use asset and a lease liability. Under the update, a distinction will exist between finance and operating type leases and the rules for determining which classification a lease will fall into are similar to existing rules. For public business entities, the amendments of this update are effective for interim and annual periods beginning after December 15, 2018. The update requires a modified retrospective transition under which comparative balance sheets from the earliest historical period presented will be revised to reflect what the financials would have looked like were the provisions of the update applied consistently in all prior periods. Management is in the process of evaluating the impacts of the update on the Company’s financial position and does not expect the requirements of the update to have a material impact on the Company’s financial position, results of operations or cash flows. Based on leases outstanding at June 30, 2017, we anticipate total assets and total liabilities will increase between $8,200,000 and $9,800,000 as the result of additional leases being recognized on our balance sheet. Decisions to repurchase, modify, or renew leases prior to the implementation date will impact the results of the Company’s final analysis.  In June 2016, the FASB issued accounting standards update 2016-13 Financial Instruments - Credit Losses, commonly referred to as “CECL”. The provisions of the update eliminate the probable initial recognition threshold under current GAAP which requires reserves to be based on an incurred loss methodology. Under CECL, reserves required for financial assets measured at amortized cost will reflect an organization’s estimate of all expected credit losses over the contractual term of the financial asset and thereby require the use of reasonable and supportable forecasts to estimate future credit losses. Because CECL encompasses all financial assets carried at amortized cost, the requirement that reserves be established based on an organization’s reasonable and supportable estimate of expected credit losses extends to held to maturity (“HTM”) debt securities. Under the provisions of the update, credit losses recognized on available for sale (“AFS”) debt securities will be presented as an allowance as opposed to a wri

Business Combination [Abstract]
Business Combination	(2) Business Combination  On March 16, 2016, the Company entered into an Agreement and Plan of Reorganization (the “Merger Agreement”) with Home State, parent company of Home State Bank, a Colorado state chartered bank headquartered in Loveland, Colorado, whereby Home State would merge into the Company. The transaction closed on September 8, 2016 with an aggregate transaction value of $152,478,000 . The Merger Agreement provided that, subject to certain conditions, Home State shareholders would receive 6,533,756 shares of Company voting common stock valued at $117,477,000 based on the Company’s closing stock price on September 8, 2016 of $17.98 , in addition to $35,001,000 in cash.  The transaction enhanced the Company’s balance sheet liquidity and supported the Company’s objective of serving the banking needs of northern Colorado business and consumer customers.  Goodwill of $56,404,000 was recognized in the transaction and represents expected synergies and cost savings resulting from combining the operations of Home State with those of the Company. Due to the tax-free structure of the transaction, the recognized goodwill was not deductible for tax purposes. The estimated fair value of assets acquired and liabilities assumed at acquisition were recorded on the Company’s balance sheet at the date of acquisition and subjected to limited measurement period adjustments in the fourth quarter 2016 as a result of receipt of final valuations. Recorded fair values of acquired assets and liabilities are subject to adjustment for up to one year from the date of the acquisition. There were no measurement period adjustments in the first or second quarter 2017.  The following table summarizes the estimated fair values of the assets acquired and liabilities assumed in the September 8, 2016 Home State transaction, and reflects all adjustments made to the fair value of the opening balance sheet through June 30, 2017:      Assets acquired:  (In thousands)  Cash and cash equivalents $ 11,849  Time deposits with banks 504  Securities available-for-sale 396,450  Securities held-to-maturity 850  Bank stocks 1,477  Net Loans 445,529  Premises and equipment, net 22,950  Other real estate owned 45  Goodwill 56,404  Other intangible assets, net 11,701  Other assets 8,118  Total assets acquired 955,877   Liabilities assumed:  Deposits 769,709  Securities sold under agreement to repurchase and federal funds purchased 19,985  Federal Home Loan Bank term notes 2,525  Federal Home Loan Bank line of credit borrowing 2,052  Other liabilities 9,128  Total liabilities assumed 803,399  Net Assets Acquired $ 152,478  No m erger expenses relating to the Home State acquisition were incurred in the first or second quarter 2017 while p re-tax merger expenses of $675,000 and $347 ,000 were included in the Company’s results of operations in the first and second quarter 2016, respectively.

In determining whether or not there is an other-than-temporary-impairment (“OTTI”) for a security, management considers many factors, including: (i) the length of time for which and the extent to which the security’s fair value has been less than cost, (ii) the financial condition and near-term prospects of the security’s issuer, (iii) whether the decline in the security’s value was affected by macroeconomic conditions, and (iv) whether the Company intends to sell the security and whether it is more likely than not that the Company will be required to sell the security before a recovery in its fair value. The assessment of whether an OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management at a particular point in time. There were no accumulated credit losses on any of the Company’s securities as of June 30, 2017 or December 31, 2016.  At June 30, 2017 , there were 221 individual securities in an unrealized loss position, including 13 individual securities that had been in a continuous unrealized loss position for 12 months or longer. Management has evaluated these securities, in addition to the remaining 208 securities in an unrealized loss position, and has determined that the decline in value since their purchase dates was primarily attributable to fluctuations in market interest rates and does not reflect a decline in the underlying issuers’ ability to repay. At December 31, 2016 , there were 271 individual securities in an unrealized loss position, including 10 individual securities that had been in a continuous unrealized loss position for 12 months or longer. The total number of securities in an unrealized loss position decreased from 271 individual securities at December 31, 2016 to 221 securities at June 30, 2017, primarily as a result of fluctuation in market interest rates . At June 30, 2017 , the Company did not intend to sell, and did not consider it likely that it would be required to sell, any of these securities prior to recovery in their fair value.  The Company’s unrated and rated municipal bond securities, along with the Company’s other rated investment securities, are subject to an annual internal review process that management has historically performed in the fourth quarter. The review process includes a review of the securities’ issuers’ most recent financial statements, including an evaluation of the expected sufficiency of the issuers’ cash flows relative to their debt service requirements. In addition, management considers any interim information made available to it that would prompt the need for more frequent review. At both J une 30, 2017 and December 31, 2016, the Company’s unrated municipal bonds comprised approximately 16.9% of the carrying value of the Company’s entire municipal bond portfolio. Securities with carrying values of $238,404,000 and $237,036,000 were pledged at June 30 , 2017 and December 31, 2016, respectively, as collateral for various lines of credit, public deposits and for other purposes as required or permitted by law. Certain mortgage backed securities with an aggregate market value of approximately $33,381,000 and $ 4 2,486,000 were pledged to secure overnight repurchase agreement borrowings as of June 30 , 2017 and December 31, 2016, respectively. Fluctuations in the fair value of these securities, and/or the fluctuation in the balance of customer repurchase agreements and or public deposits, may result in the need to pledge additional securities against these sources of funding. Management monitors the Bank’s collateral position with respect to repurchase agreement borrowings on a daily basis.

Loans [Abstract]
Loans	(4) Loans  A summary of net loans held for investment by loan type at the dates indicated is as follows:      June 30, December 31,  2017 2016   (In thousands)  Commercial and residential real estate $ 1,799,114 $ 1,768,424  Construction 99,632 88,451  Commercial 451,701 432,083  Agricultural 15,510 16,690  Consumer 122,994 125,264  SBA 47,804 52,380  Other 40,676 31,778  Total gross loans 2,577,431 2,515,070  Deferred costs and (fees) 154 (61)  Loans, held for investment, net 2,577,585 2,515,009  Less allowance for loan losses (23,125) (23,250)  Net loans, held for investment $ 2,554,460 $ 2,491,759  In the first six months of 2017, the Company purchased $58.4 million of performing loans included in commercial and consumer loans in the above table. During 2016, excluding the Home State transaction, the Company purchased $109.5 million in performing loans included in commercial and residential real estate and consumer loans in the above table. The Company recognized a $271,000 gain on the sale of its $2.0 million credit card loan portfolio during the first quarter 2017.  Activity in the allowance for loan losses for the period indicated is as follows:      Three Months Ended June 30, Six Months Ended June 30,  2017 2016 2017 2016   (In thousands)  Balance, beginning of period $ 23,175 $ 23,025 $ 23,250 $ 23,000  Provision for loan losses 206 10 211 26  Loans charged-off (338) (57) (463) (359)  Recoveries on loans previously  charged-off 82 72 127 383  Balance, end of period $ 23,125 $ 23,050 $ 23,125 $ 23,050  The Company’s additional disclosures relating to loans and the allowance for loan losses are broken out into two subsets, portfolio segment and class. The portfolio segment level is defined as the level where financing receivables are aggregated in developing the Company’s systematic method for calculating its allowance for loan losses. The class level is the second level at which credit information is presented and represents the categorization of financing related receivables at a slightly less aggregated level than the portfolio segment level. Because d ata presented according to class is dependent upon the underlying purpose of the loan, whereas loan data organized by portfolio segment is determined by the loan’s underlying collateral, disclosures broken out by portfolio segment versus class may not be in agreement. The disclosures in this footnote include both Non-PCI and PCI loans. As of June 30, 2017, PCI loans acquired in the Home State transaction are not considered material and as a result separate PCI disclosures are not included.  The following tables provide detail for the ending balances in the Company’s allowance for loan losses and loans held for investment, broken down by portfolio segment as of the dates indicated. In addition, the tables also provide a roll-forward by portfolio segment of the allowance for loan losses for the three and six months ended June 30, 2017 and June 30, 2016. The detail provided for the amount of the allowance for loan losses and loans individually versus collectively evaluated for impairment (i.e., the specific component versus the general component of the allowance for loan losses) corresponds to the Company’s systematic methodology for estimating its allowance for loan losses.

The recorded investment included in the following table represents customer balances net of any partial charge-offs recognized on the loans, net of any deferred fees and costs. The unpaid balance represents the recorded balance prior to any partial charge-offs. Interest income recognized year-to-date may exclude an immaterial amount of interest income on matured loans that are 90 days or more past due, but that are in the process of being renewed and thus are still accruing.

The gross quarter-to-date interest income that would have been recorded had the nonaccrual loans been current in accordance with their original terms was $59,000 for the second quarter 2017 and $57,000 for the second quarter 2016. During the three and six months ended June 30 , 2016, approximately $125,000 and $249,000 , respectively, in cash-basis interest income was recognized on the Company’s largest nonaccrual loan. This loan was moved into accruing status in September 2016. No cash-basis interest income was recognized in the first six months of 2017.  The following tables summarize, by class, loans classified as past due in excess of 30 days or more, in addition to those loans classified as nonaccrual:     June 30, 2017 30-89 Days Past Due 90 Days + Past Due and Still Accruing Nonaccrual Total Nonaccrual and Past Due Total Loans, Held for Investment  (In thousands)  Commercial and residential  real estate $ - $ - $ 2,154 $ 2,154 $ 1,799,222  Construction - - - - 99,638  Commercial 587 - 1,368 1,955 451,728  Consumer 370 - 193 563 123,001  Other - - 907 907 103,996  Total $ 957 $ - $ 4,622 $ 5,579 $ 2,577,585      December 31, 2016 30-89 Days Past Due 90 Days + Past Due and Still Accruing Nonaccrual Total Nonaccrual and Past Due Total Loans, Held for Investment  (In thousands)  Commercial and residential  real estate $ 1,258 $ - $ 2,835 $ 4,093 $ 1,768,381  Construction - - - - 88,449  Commercial 37 - 1,094 1,131 432,072  Consumer 42 - 201 243 125,261  Other - - 1,117 1,117 100,846  Total $ 1,337 $ - $ 5,247 $ 6,584 $ 2,515,009   The Company categorizes loans into risk categories based on relevant information about the ability of a particular borrower to service its debt, such as: current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. The Company uses the following definitions for risk ratings, which are consistent with the definitions used in supervisory guidance:  Substandard . Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral, if any, pledged to secure the loan. Loans so classified have a well-defined weakness or weaknesses that jeopardize the collection of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.  Doubtful . Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable.  Loans not meeting the criteria above are considered to be non-classified loans.  The following tables provide detail for the risk categories of loans, by class of loans, based on the most recent credit analysis performed as of the dates indicated:      June 30, 2017 Commercial & Residential Real Estate Construction Commercial Consumer Other Total  (In thousands)  Non-classified $ 1,776,772 $ 99,632 $ 448,804 $ 122,683 $ 100,465 $ 2,548,356  Substandard 22,342 - 2,897 311 3,525 29,075  Doubtful - - - - - -  Subtotal 1,799,114 99,632 451,701 122,994 103,990 2,577,431  Deferred costs and fees 108 6 27 7 6 154  Loans, held for investment, net $ 1,799,222 $ 99,638 $ 451,728 $ 123,001 $ 103,996 $ 2,577,585      December 31, 2016 Commercial & Residential Real Estate Construction Commercial Consumer Other Total  (In thousands)  Non-classified $ 1,742,974 $ 88,451 $ 427,278 $ 124,932 $ 98,561 $ 2,482,196  Substandard 25,450 - 4,805 332 2,287 32,874  Doubtful - - - - - -  Subtotal 1,768,424 88,451 432,083 125,264 100,848 2,515,070  Deferred fees and costs (43) (2) (11) (3) (2) (61)  Loans, held for investment, net $ 1,768,381 $ 88,449 $ 432,072 $ 125,261 $ 100,846 $ 2,515,009  The book balance of TDRs at June 30 , 2017 and December 31, 2016, was $ 24,211,000 and $ 25,219,000 , respectively. Management established approximately $26,000 and $ 74,000 in specific reserves for these loans as of June 30 , 2017 and December 31, 2016, respectively. The Company had an additional $1,180,000 and $2,238,000 committed on loans classified as TDRs at June 30 , 2017 and December 31, 2016, respectively.  During the six months ended June 30 , 2017, the terms of 19 loans totaling $4,067,000, were modified in troubled debt restructurings. The modification of the terms of such loans included ten restructurings of payment terms and nine loan renewals with terms more favorable to the borrowers than would otherwise be available based on the borrower's financial strength. During the three months ended June 30 , 2017, the terms of 14 loans totaling $3,036,000 , were modified in troubled debt restructurings. The modification of the terms of such loans included seven restructurings of payment terms and seven loan renewals with terms more favorable to the borrowers than would otherwise be available based on the borrower's financial strength.  During the three and six months ended June 30 , 2016, the terms of two loans totaling $1,865,000 were modified in troubled debt restructurings. The modification of the terms of such loans included one restructure of payment terms and one renewal of a loan with a stated interest rate below market. There were no material charge-offs or provisions recorded during the three and six months ended June 30 , 2017 or June 30 , 2016 on loans designated as TDRs.  For reporting purposes, a loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. There were no defaults on TDRs during the six months ended June 30 , 2017 or June 30 , 2016.

Goodwill And Other Intangible Assets [Abstract]
Goodwill And Other Intangible Assets	(5) Goodwill and Other Intangible Assets  The Company recognized $56,404,000 in goodwill as a result of the Home State transaction on September 8, 2016. Acquisition date estimates of the fair value of acquired assets and liabilities assumed remain subject to change, up to twelve months following the transaction, if additional information becomes available impacting acquisition date fair values. Subsequent changes to estimates of acquisition date fair value would impact the amount recognized as goodwill.  Other intangible assets with finite lives are amortized over their respective estimated useful lives to their estimated residual values. As of June 30, 2017, the Company had intangible assets comprised of its core deposit intangible assets and customer relationship intangible assets.  The following table presents the gross amounts of core deposit intangible assets and customer relationship intangible assets and the related accumulated amortization at the dates indicated:        June 30, December 31,  Useful Life 2017 2016   (In thousands)  Core deposit intangible assets 10 - 15 years $ 74,087 $ 74,087  Core deposit intangible assets accumulated amortization (64,116) (63,112)  Core deposit intangible assets, net $ 9,971 $ 10,975   Customer relationship intangible assets 10 years 6,243 6,243  Customer relationship intangible assets accumulated amortization (2,194) (1,901)  Customer relationship intangible assets, net $ 4,049 $ 4,342   Total other intangible assets, net $ 14,020 $ 15,317

Borrowings [Abstract]
Borrowings	(6) Borrowings  At June 30 , 2017 , the Company’s outstanding borrowings were $ 162,672,000 as compared to $ 197,168,000 at December 31, 2016. These borrowings at June 30 , 2017 consisted of $71 ,772,000 in term notes and $90,900,000 of advances on our line of credit, both with the Federal Home Loan Bank (the “FHLB”). At December 31, 2016, outstanding borrowings consisted of $72,477,000 of term notes and $124,691,000 in advances on our line of credit, both with the FHLB. The interest rate on the FHLB line of credit varies with the federal funds rate and was 1.24 % at June 30 , 2017 . The Company has four term notes with the FHLB. Two of the term notes have fixed interest rates, the first is a $20,000,000 term note at 2.52% that is payable at its matu rity date of January 23, 2018 , with a prepayment penalty if paid prior to maturity; it is convertible to floating rate on pred etermined conversion dates at the discretion of the FHLB. If the note is converted by the FHLB, the Bank has the option to prepay the note without penalty. If the note is not converted by the FHLB, the note continues to be convertible quarterly thereafter, with the option to convert to floating rate at the discretion of the FHLB. The second fixed rate term note of $1,740,000 carries an interest rate of 5.63% and matures August 30, 2017 . As a result of the Home State transaction, the Company recognized a premium on Home State borrowings at acquisition of $90,000 ; the premium had a balance of $32,000 as of June 30 , 2017. Additionally, the Company had two $25,000,000 variable rate term notes that mature on August 4, 2017 and March 7, 2018 and carry an interest rate that resets quarterly. As of June 30 , 2017, the rates on our variable rate term notes were set at 1.25% and 1.19% , respectively.  The Company has an advance, pledge and security agreement with the FHLB and had pledged qualifying loans and securities in the amount of $ 683,565,000 at June 30 , 2017 an d $ 597,202,000 at December 31, 2016.

Subordinated Debentures And Trust Preferred Securities [Abstract]
Subordinated Debentures and Trust Preferred Securities	(7) Subordinated Debentures and Trust Preferred Securities  At June 30 , 2017, the Company’s outstanding subordinated debentures (the “Debentures”) consisted of $65,774,000 in debt, partially offset by $751,000 in debt issuance costs. At December 31, 2016 the Company’s outstanding Debentures consisted of $65,774,000 in debt, partially offset by $793,000 in debt issuance costs. As of June 30 , 2017 , the Company's Debentures bore a weighted average cost of funds of 5.06% .  The Company’s Debentures were issued in three separate series. The first two issuances have maturities of 30 years from the date of issuance. These two issuances of Debentures were issued to trusts established by the Company, which in turn issued $ 25,000,000 of trust preferred securities (“TruPS”). Generally, and with certain limitations, the Company is permitted to call the Debentures subsequent to the first five or ten years, as applicable, after issuance, if certain conditions are met, or at any time upon the occurrence and continuation of certain changes in either the tax treatment or the capital treatment of the trusts, the Debentures or the preferred securities. The Guaranty Capital Trust III TruPS became callable at each quarterly interest payment date starting on July 7, 2008. The CenBank Trust III TruPS became callable at each quarterly interest payment date starting on April 15, 2009.  The third issuance was executed on July 18, 2016 in anticipation of the Home State transaction, in order to fund the cash consideration to be paid to Home State shareholders in conjunction with the transaction. The issuance was comprised of $ 40,000,000 of 5.75% Fixed-to-Floating Rate Subordinated Notes (the “Notes”) due July 20, 2026. The Notes initially bear a fixed interest rate of 5.75% per annum, payable semi-annually in arrears. On July 20, 2021, and, thereafter, the interest on the Notes will be payable quarterly in arrears, at an annual floating rate equal to three-month LIBOR as determined by the applicable quarterly period, plus 4.73% .  As of June 30 , 2017, the Company was in compliance with all financial covenants of the Debentures.  The Company had accrued, unpaid interest on its Debentures of approximately $1,288,000 at June 30 , 2017 and approximately $1,286,000 at December 31, 2016. Interest payable on Debentures is included in interest payable and other liabilities on the consolidated balance sheets.  The Company is not considered the primary beneficiary of the trusts that issued the TruPS (variable interest entities); therefore, the trusts are not consolidated in the Company’s financial statements and the Debentures are shown as liabilities. The Company’s investment in the common stock of each trust is included in other assets in the Company’s consolidated balance sheets.  Although the securities issued by each of the trusts are not included as a component of stockholders’ equity in the consolidated balance sheets, they are treated as capital for regulatory purposes. Specifically, under applicable regulatory guidelines, the $25,000,000 of TruPS issued by the trusts qualify as Tier 1 capital, up to a maximum of 25 % of capital on an aggregate basis. Any amount that exceeds 25 % qualifies as Tier 2 capital. At June 30 , 2017, the full $ 25,000,000 of the TruPS qualified as Tier 1 capital. The $40,000,000 issuance from July 2016 qualifies for inclusion in Tier 2 capital.  Under the Dodd-Frank Act and a joint rule from the Federal Reserve Board, the Office of the Comptroller of the Currency, and the FDIC, certain TruPS are no longer eligible to be included as Tier 1 capital for regulatory purposes. However, an exception to this statutory prohibition applies to securities issued prior to May 19, 2010 by bank holding companies with less than $ 15 billion of total assets. As we have less than $ 15 billion in total assets and issued all of our TruPS prior to May 19, 2010, we expect that our TruPS will continue to be eligible to be treated as Tier 1 capital, subject to other rules and limitations.

Commitments [Abstract]
Commitments	 (8) Commitments  The Bank enters into credit-related financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and commercial letters of credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets.  The Bank’s exposure to credit loss is represented by the contractual amount of these commitments. The Bank follows the same credit policies in making commitments, including obtaining collateral, if necessary, as it does for on-balance sheet instruments.  At the dates indicated, the following financial instruments were outstanding whose contract amounts represented credit risk:     June 30, 2017 December 31, 2016   (In thousands)  Commitments to extend credit:  Variable $ 441,849 $ 436,546  Fixed 120,570 95,607  Total commitments to extend credit $ 562,419 $ 532,153   Standby letters of credit $ 12,827 $ 10,292  At June 30 , 2017 , the rates on the fixed rate commitments to extend credit ranged from 2.02 % to 7.75 %.  A commitment to extend credit is an agreement to lend to a customer as long as there is no violation of any condition established in the underlying contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Commitments may expire without being fully drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. Off-balance sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated.  A commitment to extend credit under an overdraft protection agreement is a commitment for a possible future extension of credit to an existing deposit customer. These lines of credit are uncollateralized and usually do not contain a specified maturity date and may not be drawn upon to the total extent to which the Bank is committed.  Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. These letters of credit are primarily issued to support public and private borrowing arrangements. A majority of letters of credit issued have expiration dates within one year. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank holds collateral supporting those commitments if deemed necessary.

Fair Value Measurements And Fair Value Of Financial Instruments [Abstract]
Fair Value Measurements and Fair Value of Financial Instruments	(9) Fair Value Measurements and Fair Value of Financial Instruments  Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:  Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets.  Level 2 - Significant other observable inputs other than Level 1 prices such as quoted prices in markets that are not active, quoted prices for similar assets or other inputs that are observable, either directly or indirectly, for substantially the full term of the asset.  Level 3 - Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.  A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Transfers of financial instruments between levels within the fair value hierarchy are recognized on the date management determines that the underlying circumstances or assumptions have changed.  Fair values of our securities are determined through the utilization of evaluated pricing models that vary by asset class and incorporate available market information (Level 2). The evaluated pricing models apply available information, as applicable, through processes such as benchmark curves, benchmarking of like securities, sector groupings and matrix pricing to prepare evaluations. These models assess interest rate impact, develop prepayment scenarios and take into account market conventions. For securities where routine valuation techniques are not used, management utilizes a discounted cash flow model with market-adjusted discount rates or other unobservable inputs to estimate fair value. Due to the lack of ratings available on these securities, management determined that a relationship to other benchmark quoted securities was unobservable, and as a result, these securities should be classified as Level 3 (Level 3 inputs). The valuation of the Company’s Level 3 bonds is highly sensitive to changes in unobservable inputs.  Currently, the Company uses interest rate swaps to help manage interest rate risk. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments (or receipts) and the discounted expected variable cash receipts (or payments). The variable cash receipts (or payments) are based on the expectation of future interest rates (forward curves) derived from observed market interest rate curves (Level 2 inputs). The Company considers the value of the swaps to be sensitive to fluctuations in interest rates.  Financial Assets and Liabilities Measured on a Recurring Basis  Assets and liabilities measured at fair value on a recurring basis are summarized below:     Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Balance  (In thousands)  Assets/(Liabilities) at June 30, 2017  State and municipal securities $ - $ 50,065 $ 31,595 $ 81,660  Mortgage-backed securities – agency /  residential - 120,354 - 120,354  Mortgage-backed securities – private /  residential - 225 - 225  Corporate securities - 87,626 - 87,626  Collateralized loan obligations - 16,045 16,045  Interest rate swaps - cash flow hedge - (1,730) - (1,730)   Assets/(Liabilities) at December 31, 2016  State and municipal securities $ - $ 49,856 $ 31,752 $ 81,608  Mortgage-backed securities – agency /  residential - 129,832 - 129,832  Mortgage-backed securities – private /  residential - 265 - 265  Corporate securities - 86,246 - 86,246  Collateralized loan obligations - 26,277 26,277  Interest rate swaps - cash flow hedge - (1,929) - (1,929)   There were no transfers of financial assets and liabilities among Level 1 , Level 2 and Level 3 during the six months ended June 30 , 2017 .

Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.  Certain financial instruments and all nonfinancial instruments are excluded from the disclosure requirements. Therefore, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.  The following methods and assumptions are used by the Company in estimating fair value disclosures for financial instruments:  (a) Cash and Cash Equivalents  The carrying amounts of cash and short-term instruments approximate fair values (Level 1).  (b) Securities and Bank Stocks  Fair values for securities available for sale and held to maturity are generally determined through the utilization of evaluated pricing models that vary by asset class and incorporate available market information (Level 2). The evaluated pricing models apply available information, as applicable, through processes such as benchmark curves, benchmarking of like securities, sector groupings and matrix pricing to prepare evaluations. These models assess interest rate impact, develop prepayment scenarios and take into account market conventions. For positions that are not traded in active markets or are subject to transfer restrictions (i.e., bonds valued with Level 3 inputs), management uses a combination of reviews of the underlying financial statements, appraisals and management’s judgment regarding credit quality and intent to sell in order to determine the value of the bond.  It is not practical to determine the fair value of bank stocks due to restrictions placed on the transferability of FHLB stock, Federal Reserve Bank stock and Bankers’ Bank of the West stock. These three stocks comprise the majority of the balance of the Company’s bank stocks .  (c) Loans Held for Investment  For variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values (Level 3). Fair values for other loans (e.g., commercial real estate and investment property mortgage loans and commercial loans) are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality (Level 3). Impaired loans are valued at the lower of cost or fair value when specific reserves are attributed to these loans because the present value of expected cash flows or the net realizable value of collateral is less than the impaired loan’s recorded investment. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price.  (d) Loans Held for Sale  Loans held for sale are carried at the lower of cost or fair value, with fair value determined by the sales price agreed upon in negotiation with the purchaser (Level 1).  (e) Deposits  The fair values of demand deposits (e.g., interest and non-interest checking, passbook savings and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount) (Level 2). The carrying amounts of variable rate, fixed-term money market accounts and certificates of deposit approximate their fair values at the reporting date (Level 2). Fair values for fixed rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits (Level 2).  (f) Short-term Borrowings  The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings maturing within 90 days approximate their fair values (Level 2).  (g) Long-term Borrowings  The fair values of the Company’s long-term borrowings are estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements (Level 2).  (h) Subordinated Debentures  The fair values of the Company’s subordinated debentures are estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements (Level 3).  (i) Accrued Interest Receivable/Payable  The carrying amounts of accrued interest approximate fair value (Level 2).  (j) Interest Rate Swaps, net  The fair value of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments (or receipts) and the discounted expected variable cash receipts (or payments). The variable cash receipts (or payments) are based on the expectation of future interest rates (forward curves) derived from observed market interest rate curves (Level 2).  (k) Off-balance Sheet Instruments  Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The fair value of commitments is not material.

Derivatives And Hedging Activities [Abstract]
Derivatives And Hedging Activities	 (10) Derivatives and Hedging Activities  The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company utilizes derivative financial instruments to assist in the management of interest rate risk, primarily helping to secure long-term borrowing rates. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the payment or receipt of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash payments or receipts principally related to certain variable-rate borrowings. The Company does not use derivatives for trading or speculative purposes.  The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the consolidated balance sheet as of June 30 , 2017 and December 31, 2016 :      Balance Fair Value  Sheet June 30, December 31,  Location 2017 2016   (In thousands)  Derivatives designated as hedging instruments  Assets:  Interest rate swaps Other assets $ - $ -  Liabilities:  Interest rate swaps Other liabilities $ 1,730 $ 1,929  The Company’s objectives in using interest rate derivatives are to add stability and predictability to interest expense and to manage the Company’s exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. For hedges of the Company’s variable-rate borrowings, interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed payments. As of June 30 , 2017 , the Company had two forward-starting interest rate swaps with an aggregate notional amount of $50,000,000 that were each designated as cash flow hedges associated with the Company’s forecasted variable-rate borrowings. The first $25,000,000 swap became effective in June 2015 at a fixed rate of 2.46% and matures in June 2020. The second $25,000,000 swap became effective in March 2016 at a fixed rate of 3.00% and matures in March 2021.  Summary information about the interest-rate swaps designated as cash flow hedges as of June 30, 2017 and December 31, 2016 is included in the table below:     June 30, 2017 December 31, 2016   (Dollars in thousands)  Notional amounts $ 50,000 $ 50,000  Weighted average pay rates 2.73 % 2.73 %  Weighted average receive rates 3 month LIBOR 3 month LIBOR  Weighted average maturity 3.4 years 3.9 years  Unrealized gains (losses) $ (1,730) $ (1,929)   The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in AOCI and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. The Company’s cash flow hedges are used to hedge the forecasted variable cash outflows associated with forecasted issuances of FHLB advances. During the six months ended June 30, 2017 and June 30 , 2016 , the income statement effect of hedge ineffectiveness was not material.  Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate liabilities. Management expects that, during the next 12 months, approximately $659,000 will be reclassified from AOCI into interest expense.  The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with another third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The impact of these customer interest rate swaps on the Company’s financial statements was immaterial for the periods covered by this report.  The table below presents the effect of the Company’s derivative financial instruments on both comprehensive income and net income for the three and six months ended June 30, 2017 and June 30, 2016 :      Income Three Months Ended Six Months Ended  Interest Rate Swaps with Statement June 30, June 30,  Hedge Designation Location 2017 2016 2017 2016   (In thousands)  Gain or (loss) recognized in OCI on  derivative - net of tax Not applicable $ (163) $ (316) $ (136) $ (1,198)  (Gain) or loss reclassified from  accumulated OCI into income  (effective portion) - net of tax Interest expense 125 163 260 265  The Company has agreements with its derivative counterparties that contain a cross-default provision whereby if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company has minimum collateral posting thresholds with certain of its derivative counterparties and as of June 30, 2017 had posted $3,842,000 against its obligations under these agreements. If the Company had breached any of these provisions at June 30, 2017 , it could have been required to settle its obligations under the agreements at the termination value.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	 (12) Stock-Based Compensation  Under the Company’s Incentive Plan, which expired by its terms on April 4, 2015, the Company’s Board of Directors had the authority to grant stock-based compensation awards prior to the plan’s expiration. Under the 2015 Plan, which was approved by the Company’s stockholders at the May 5, 2015 annual meeting, the Company’s Board of Directors maintains the authority to grant stock-based compensation awards to nonemployee directors, key employees, consultants and prospective employees.  S tock-based compensation awards issuable under the 2015 Plan include, and that were issuable under the Incentive Plan included, the grant of stock-based compensation awards in the form of options, restricted stock awards, restricted stock unit awards, performance stock awards, stock appreciation rights and other equity based awards. Likewise, the Incentive Plan provided for, and the 2015 Plan provides, that eligible participants may be granted shares of Company common stock that are subject to forfeiture until the grantee vests in the stock award based on the established conditions, which may include service conditions, established performance measures or both.  Prior to the vesting of stock awards that are subject to a service vesting condition, each grantee has the rights of a stockholder with respect to voting the shares of stock represented by the award. The grantee is not entitled to dividend rights with respect to the shares of stock until vesting occurs. Prior to vesting of the stock awards with performance vesting conditions, each grantee has the rights of a stockholder with respect to voting of the shares of stock represented by the award. The recipient is generally not entitled to dividend rights with respect to unvested shares. Other than the stock awards with service and performance-based vesting conditions, no other grants have been made under the Incentive Plan or the 2015 Plan.  Under the provisions of the 2015 Plan and the Incentive Plan, grants of stock-based compensation awards of 935,000 and 1,700,000 shares , respectively, were authorized , subject to adjustments upon the occurrence of certain events. As of June 30, 2017 , there were 2 64,458 and 2 23,536 outstanding awards under the 2015 Plan and the Incentive Plan, respectively. As of June 30, 2017 , there were 615,095 shares remaining available for grant under the 2015 Plan.  Of the 487,994 shares represented by unvested awards at June 30, 2017 , approximately 469 ,000 shares are expected to vest. At June 30, 2017, the re were 292 ,368 shares of restricted stock outstanding that were subject to a performance condition. As of June 30, 2017 , management expects that approximately 282,000 of these shares will vest and that the remaining shares will expire unvested. The performance shares that are expected to vest relate to awards granted to various key employees from March 2014 through May 2017. The vesting of these performance shares is contingent upon meeting certain return on average asset performance measures. The performance-based shares awarded in 2014, 2015, 2016 and 2017 each include a “threshold” and “target” performance level, with vesting determined based on where actual performance falls in relation to the numeric range represented by these performance criteria. As of June 30, 2017 , management expected that all of the performance awards made in 2014, 2015, 2016 and 2017 not forfeited from a failure by the grantee to provide the requisite service will vest, which is consistent with the level of expense currently being recognized over the vesting period. Should this expectation change, the recognition of compensation expense in future periods could be impacted.  A summary of the status of unearned stock awards and the change during the six months ended June 30 , 2017 is presented in the table below:     Shares Weighted Average Fair Value on Award Date  Unearned at January 1, 2017 513,187 $ 14.39  Awarded 114,302 24.89  Forfeited (2,621) 14.58  Vested (136,874) 13.86  Unearned at June 30, 2017 487,994 $ 17.00  The Company recognized $ 1,502,000 and $ 1,566,000 in stock-based compensation expense for services rendered for the six months ended June 30, 2017 and June 30, 2016 , respectively. The income tax benefit recognized on share-based compensation recorded during the six months ended June 30, 2017 and June 30, 2016 , was $571,000 and $595,000 , respectively. The income tax benefit recognized on share-based compensation recorded during the three months ended June 30, 2017 and June 30, 2016 , was $287,000 and $277,000 , respectively. In addition to the tax benefit on recorded share-based compensation expense, the Company recognized an excess tax benefit of $560,000 and $321,000 during the six months ended June 30 , 2017 and June 30, 2016, respectively. Likewise the excess tax benefit recognized during the second quarter 2017 and 2016 was $49,000 and $1,000 , respectively. The excess tax benefit represents the appreciation of the stock price on vested restricted stock between the grant date and the vesting date multiplied by the number of shares vested during the period. The grant date fair value of restricted stock awards granted in the six months ended June 30, 2017 and June 30, 2016 was $2,845,000 and $2,538, 000 , respectively. The fair value of awards that vested in the six months ended June 30, 2017 and June 30, 2016 was approximately $3,369,000 and $2,966,000 , respectively. At June 30 , 2017 , compensation cost of $ 4,969,000 related to unvested awards not yet recognized is expected to be recognized over a weighted-average period of 1.6 years.

Legal Contingencies [Abstract]
Legal Contingencies	(14) Legal Contingencies  The Company and the Bank are defendants, from time to time, in legal actions at various points of the legal process, including appeals, arising from transactions conducted in the ordinary course of business. Management believes, after consultation with legal counsel, that it is not probable that the outcome of current legal actions will result in a liability that has a material adverse effect on the Company’s consolidated financial position, results of operations, comprehensive income or cash flows. In the event that such legal action results in an unfavorable outcome, the resulting liability could have a material adverse effect on the Company’s consolidated financial position, results of operations, comprehensive income or cash flows.

Subsequent Events [Abstract]
Subsequent Events	 (15) Subsequent Events  On July 18, 2017, the Company entered into an Agreement and Plan of Reorganization (the “Castle Rock Merger Agreement”) with Castle Rock Bank Holding Company (“Castle Rock”), parent company of Castle Rock Bank, a Colorado state chartered bank headquartered in Castle Rock, Colorado. Subject to the terms and conditions set forth in the Castle Rock Merger Agreement, Castle Rock would be merged with and into the Company, with the Company continuing as the surviving corporation. The Castle Rock Merger Agreement also provides that following the merger, Castle Rock Bank would be merged with and into the Bank, with the Bank continuing as the surviving bank. As of June 30, 2017, the pro forma combined Company would have approximately $3.6 billion in total assets and $2.9 billion in total deposits. The transaction is expected to close during the first quarter 2018, pending regulatory and Castle Rock shareholder approval. The transaction will be accounted for using the acquisition method of accounting which requires the assets acquired and liabilities assumed to be recognized at their fair values as of the acquisition date.

Organization, Operations And Basis Of Presentation [Abstract]
Basis of Presentation	(a) Basis of Presentation  The accounting and reporting policies of the Company conform to generally accepted accounting principles in the United States of America. All material intercompany balances and transactions have been eliminated in consolidation. The Company’s financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of its financial position and results of operations for the periods presented. All such adjustments are of a normal and recurring nature. Subsequent events have been evaluated through the date of financial statement issuance.  Certain information and note disclosures normally included in consolidated financial statements, prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States of America, have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The interim operating results presented in these financial statements are not necessarily indicative of operating results for the full year. For further information, refer to the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.
Business Combinations	(b) Business Combinations  The Company accounts for acquisitions of businesses using the acquisition method of accounting. Under the acquisition method, assets acquired and liabilities assumed are recorded at their estimated fair value upon the date of acquisition. Management utilizes various valuation techniques including discounted cash flow analyses to determine the fair values of assets acquired and liabilities assumed. Any excess of purchase price over amounts allocated to the acquired assets, including identifiable intangible assets, and liabilities assumed is recorded as goodwill. 
Use of Estimates	(c) Use of Estimates  The preparation of the consolidated financial statements, in conformity with U.S. GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the consolidated balance sheets and income and expense for the periods presented. Actual results could differ significantly from those estimates. 
Loans and Loan Commitments	 (d) Loans and Loan Commitments  The Company extends commercial, real estate and consumer loans to customers. A substantial portion of the loan portfolio consists of commercial and real estate loans throughout the Front Range of Colorado. The ability of the Company’s borrowers to honor their loan contracts is generally dependent upon the real estate and general economic conditions prevailing in Colorado, among other factors.  Purchased loans, that on the date of acquisition reflected evidence of credit deterioration since origination and for which collection of all contractually required payments was not probable were designated as purchased credit impaired or “PCI” loans. In the September 8, 2016 Home State transaction, the Company designated $2,108,000 of loans as PCI. As of June 30, 2017, $1,290,000 in PCI loans remained in the Company’s loan portfolio. Loans not designated as PCI (“Non-PCI” loans) comprise the significant majority of the Company’s loan portfolio and consist of internally originated loans in addition to acquired loans. Acquired Non-PCI loans were designated as such as of the date of acquisition for one of or both of the following reasons: (1) management considered the collection of all contractually required payments probable, and (2) the loan demonstrated no evidence of credit deterioration since origination.  Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, are reported at their outstanding unpaid principal balances, adjusted for charge-offs, the allowance for loan losses, acquisition-related discounts and any deferred fees or costs. Acquired loans are recorded upon acquisition at fair value, with no associated allowance for loan loss. However, if subsequent to acquisition, the credit quality of an acquired loan deteriorates, an allowance may be required. Accounting for loans is performed consistently across all portfolio segments and classes.  A portfolio segment is defined in accounting guidance as the level at which an entity develops and documents a systematic methodology to determine its allowance for loan losses. A class is defined in accounting guidance as a group of loans having similar initial measurement attributes, risk characteristics and methods for monitoring and assessing risk.  Interest income is accrued on the unpaid principal balance of the Company’s loans. Loan origination fees, net of direct origination costs, are deferred and recognized as an adjustment to the related loan yield using the effective interest method without anticipating prepayments. Purchase discount or premium on acquired Non-PCI loans is recognized as an adjustment to interest income over the contractual life of such loans using the effective interest method, or taken into income when the related loans are paid off or sold. With respect to PCI loans, the “accretable yield”, calculated as the excess of undiscounted expected cash flows at acquisition over the fair value at acquisition, is accreted into income over the term of the loan assuming the amount and timing of cash flows are reasonably estimable.  The accrual of interest on loans is discontinued (and the loan is put on nonaccrual status) at the time the loan is 90 days past due unless the loan is well secured and in process of collection. The time at which a loan enters past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off prior to the date on which they would otherwise enter past due status if collection of principal or interest is considered doubtful. The interest on a nonaccrual loan is accounted for using the cost-recovery or cash-basis method until the loan qualifies for a return to the accrual-basis method. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero, with payments received being applied first to the principal balance of the loan. Under the cash-basis method, interest income is recognized when the payment is received in cash. A loan is returned to accrual status after the delinquent borrower’s financial condition has improved, when all the principal and interest amounts contractually due are brought current, and when the likelihood of the borrower making future timely payments is reasonably assured.  Financial instruments include off ‑balance sheet credit instruments, such as commitments to make loans and commercial letters of credit issued to meet customer financing needs. The face amount of each item represents the Company’s total exposure to loss with respect to the item before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Allowance for Loan Losses and Allowance for Unfunded Commitments	(e) Allowance for Loan Losses and Allowance for Unfunded Commitments  The allowance for loan losses, or “the allowance”, is a valuation allowance for probable incurred loan losses and is reported as a reduction of outstanding loan balances.  Management evaluates the amount of the allowance on a regular basis based upon its periodic review of the collectability of the Company’s loans. Factors affecting the collectability of the loans include historical loss, the nature and volume of the loan portfolio, adverse situations that may affect borrowers’ ability to repay, estimated value of any underlying collateral, prevailing economic conditions and historical loss experience. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. Management maintains the allowance at a level that it deems appropriate to adequately provide for probable incurred losses in the loan portfolio and other extensions of credit. The Company’s methodology for estimating the allowance is consistent across all portfolio segments and classes of loans.  Loans deemed to be uncollectable are charged-off and deducted from the allowance. The Company’s loan portfolio primarily consists of non-homogeneous commercial and real estate loans where charge-offs are considered on a loan-by-loan basis based on the facts and circumstances, including management’s evaluation of collateral values in comparison to book values on collateral-dependent loans. Charge-offs on smaller balance unsecured homogenous type loans, such as overdrafts and ready reserves are recognized by the time the loan in question is 90 days past due. The provision for loan losses and recoveries on loans previously charged-off are added to the allowance.  The allowance consists of both specific and general components. The specific component relates to loans that are individually classified as impaired. All loans are subject to individual impairment evaluation should the pertinent facts and circumstances suggest that such evaluation is necessary. Factors considered by management in determining impairment include the loan’s payment status and the probability of collecting scheduled principal and interest payments when they become due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. 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 original underlying loan agreement. 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. If a loan is impaired, a portion, if any, of the allowance is allocated so that the loan is reported at the present value of estimated future cash flows using the loan’s original contractual rate or at the fair value of collateral, less estimated selling costs, if repayment is expected solely from collateral. Troubled debt restructurings (“TDRs”) are separately identified for impairment disclosures. If a TDR is considered to be a collateral-dependent loan, impairment of the loan is measured using the fair value of the collateral, less estimated selling costs. Likewise, if a TDR is not collateral-dependent, impairment is measured using the present value of estimated future cash flows using the loan’s effective rate at inception. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with its accounting policy for the allowance.  The general component of the allowance covers all other loans not specifically identified as impaired and is determined by calculating losses recognized by portfolio segment during the current credit cycle and adjusted based on management’s evaluation of various qualitative factors. In performing this calculation, loans are aggregated into one of three portfolio segments: Real Estate, Consumer and Commercial & Other. An assessment of risks impacting loans in each of these portfolio segments is performed and qualitative adjustment factors, which will adjust the historical loss rate, are estimated. These qualitative adjustment factors consider current conditions relative to conditions present throughout the current credit cycle in the following areas: credit quality, loan class concentration levels, economic conditions, loan growth dynamics and organizational conditions. The historical loss experience is adjusted for management’s estimate of the impact of these factors based on the risks present for each portfolio segment.  The Company recognizes a liability in relation to unfunded commitments that is intended to represent the estimated future losses on commitments. In calculating the amount of this liability, management considers the amount of the Company’s off-balance sheet commitments, estimated utilization factors and loan specific risk factors. The Company’s liability for unfunded commitments is calculated quarterly and the liability is included under “other liabilities” in the consolidated balance sheet. 
Goodwill And Other Intangible Assets	(f) Goodwill and Other Intangible Assets  Goodwill was recorded in the Home State transaction and represents the excess of the purchase price over the fair value of acquired tangible assets, identifiable intangible assets and liabilities. Goodwill is assessed at least annually for impairment and any such impairment is recognized in the period identified.  Intangible assets acquired in a business combination are amortized over their estimated useful lives to their estimated residual values and evaluated for impairment whenever changes in circumstances indicate that such an evaluation is necessary.  Core deposit intangible assets (“CDI assets”) are recognized at the time of their acquisition based on valuations prepared by independent third parties or other estimates of fair value. In preparing such valuations, management considers variables such as deposit servicing costs, attrition rates and market discount rates. CDI assets are amortized to expense over their useful lives, ranging from 10 years to 15 years.  Customer relationship intangible assets are recognized at the time of their acquisition based upon management’s estimate of their fair value. In preparing their valuation, management considers variables such as growth in existing customer base, attrition rates and market discount rates. The c ustomer relationship intangible assets are amortized to expense over their estimated useful life, which has been estimated to be 10 years. The Company has recognized three customer relationship intangible assets as a result of the acquisitions of PCM on July 31, 2012, Cherry Hills Investment Advisers Inc. on July 16, 2014 and Home State on September 8, 2016. 
Derivative Instruments	(g) Derivative Instruments  The Company records all derivatives on its consolidated balance sheets at fair value. At the inception of a derivative contract, the Company designates the derivative as one of three types based on the Company’s intentions and belief as to the derivative’s likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). To date, the Company has entered into cash flow hedges and stand-alone derivative agreements but has not entered into any fair value hedges. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction impacts earnings. Any portion of the cash flow hedge not deemed highly effective in hedging the changes in expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings as noninterest income.  The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the derivative contract. This documentation includes linking cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the hedge is highly effective in offsetting changes in cash flows of the hedged items.
Stock Incentive Plan	 (h) Stock Incentive Plan  The Company’s Amended and Restated 2005 Stock Incentive Plan (the “Incentive Plan”) provided for the grant of equity-based awards representing up to a total of 1,700,000 shares of voting common stock to key employees, nonemployee directors, consultants and prospective employees. The Incentive Plan expired by its terms on April 4, 2015. At the Company’s annual meeting of stockholders on May 5, 2015, the Company’s stockholders approved the Guaranty Bancorp 2015 Long-Term Incentive Plan (the “2015 Plan”), which had been previously approved by the Company’s Board of Directors. The 2015 Plan provides for the grant of stock options, stock awards, stock unit awards, performance stock awards, stock appreciation rights and other equity-based awards representing up to a total of 935,000 shares of voting common stock to key employees, nonemployee directors, consultants and prospective employees. All awards issued under the Incentive Plan will remain outstanding in accordance with their terms despite the expiration of the Incentive Plan; however, any awards granted subsequent to the expiration of the Incentive Plan have been, and will continue to be, issued under the 2015 Plan.  As of June 30, 2017, the Company had granted stock awards under both the Incentive Plan and the 2015 Plan. The Company recognizes stock compensation expense for services received in a share-based payment transaction over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. The compensation cost of employee and director services received in exchange for stock awards is based on the grant date fair value of the award, as determined by quoted market prices. Stock compensation expense is recognized using an estimated forfeiture rate, adjusted as necessary to reflect actual forfeitures. The Company has issued stock awards that vest based on the passage of time over service periods of one to five years (in some cases vesting in annual installments, in other cases cliff vesting at the end of the service period) and other stock awards that vest contingent upon the satisfaction of certain performance conditions. The last date on which outstanding performance stock awards may vest is February 15, 2020. Compensation cost related to the performance stock awards is recognized based on an evaluation of expected financial performance in comparison to established criteria . Should expectations of the Company’s future financial performance change, expense to be recognized in future periods could be impacted. 
Stock Repurchase Plan	(i) Stock Repurchase Plan  On February 7, 2017, the Company’s Board of Directors authorized the extension of the expiration date of the Company’s share repurchase program originally announced in April 2014. Due to previous extensions the program was scheduled to expire on April 2, 2017, however, this most recent extension extends the expiration date of the repurchase program through April 2, 2018. Pursuant to the program, the Company may repurchase up to 1,000,000 shares of its voting common stock, par value $0.001 per share. As of the date of this filing, the Company had not repurchased any shares under the program.
Income Taxes	(j) Income Taxes  Income tax expense is the total of the current year’s income tax payable or refundable and the increase or decrease in deferred tax assets and liabilities. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period of the enactment date.  Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that the Company will not realize some portion of or the entire deferred tax asset. At June 30, 2017 and December 31, 2016, the Company had a net deferred tax asset of $2,990,000 and $4,846,000 , respectively, which includes the deferred tax asset (liability) associated with the net unrealized loss (gain) on securities and interest rate swaps. After analyzing the composition of, and changes in, the deferred tax assets and liabilities and considering the Company’s forecasted future taxable income and various tax planning strategies, including the intent to hold the securities available for sale that were in a loss position until maturity, management determined that as of June 30, 2017, it was “more likely than not” that the net deferred tax asset would be fully realized. As a result, there was no valuation allowance with respect to the Company’s deferred tax asset as of June 30, 2017 or December 31, 2016.  The Company and the Bank are subject to U.S. federal income tax, State of Colorado income tax and income tax in other states. Generally, the Company is no longer subject to examination by Federal taxing authorities for years before 2013 and is no longer subject to examination by the State of Colorado for years before 2012. The Company recognizes interest related to income tax matters as interest expense and penalties related to income tax matters as other noninterest expense. At June 30, 2017 and December 31, 2016, the Company did no t have any amounts accrued for interest or penalties. 
Earnings Per Common Share	(k) Earnings per Common Share  Basic earnings per common share represents the earnings allocable to common stockholders divided by the weighted average number of common shares outstanding during the period. Dilutive common shares that may be issued by the Company represent unvested stock awards subject to a service or performance condition.  Earnings per common share have been computed based on the following calculation of weighted average shares outstanding:      Three Months Ended June 30, Six Months Ended June 30,  2017 2016 2017 2016   Average common shares outstanding 27,913,082 21,242,520 27,890,446 21,213,706  Effect of dilutive unvested stock grants (1) 182,789 135,829 230,300 224,075  Average shares outstanding for calculated  diluted earnings per common share 28,095,871 21,378,349 28,120,746 21,437,781  _____________    (1) Unvested stock grants representing 487,994 shares at June 30 , 2017 had a dilutive impact of 182,789 and 230,300 shares in the diluted earnings per share calculation for the three and six months ended June 30 , 2017, respectively. Unvested stock grants representing 554,591 shares at June 30 , 2016 had a dilutive impact of 135,829 and 224,075 shares in the diluted earnings per share calculation for the three and six months ended June 30 , 2016, respectively. 
Recently Issued Accounting Standards	(l) Recently Issued Accounting Standards  Adoption of New Accounting Standards:  In March 2016, the FASB issued accounting standards update 2016-09 Compensation-Stock Compensation. The purpose of the update was to simplify the accounting for share-based payment transactions, including the income tax consequences of such transactions. Under the provisions of the update, the income tax consequences of excess tax benefits and deficiencies should be recognized in income tax expense in the reporting period in which the awards vest. Previously, excess tax benefits or deficiencies impacted stockholder’s equity directly to the extent there was a cumulative excess tax benefit. In the event that a tax deficiency had occurred during the reporting period and a cumulative excess tax benefit did not exist, the tax deficiency was recognized in income tax expense under previous GAAP. The update also provides that entities may continue to estimate forfeitures in accounting for stock-based compensation or recognize them as they occur. The provisions of this update become effective for interim and annual periods beginning after December 15, 2016, however early adoption was permitted beginning in 2016. The Company adopted the provisions of the update in the fourth quarter 2016. During the first six months of 2017, $560,000 of excess tax benefits related to restricted stock vestings reduced income tax expense. Comparatively, excess tax benefits of $321,000 were retroactively recognized in the first six months of 2016, upon adoption in the fourth quarter 2016.  Recently Issued but not yet Effective Accounting Standards:  In May 2014, the FASB issued accounting standards update 2014-09 Revenue from Contracts with Customers. The main provisions of the update require the identification of performance obligations within a contract and require the recognition of revenue based on a stand-alone allocation of contract revenue to each performance obligation. Performance obligations may be satisfied and revenue recognized over a period of time if: (i) the customer simultaneously receives and consumes the benefits provided by the entity’s performance as the entity performs, or (ii) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or (iii) the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. For public business entities, the amendments of this update are effective beginning with interim and annual reporting periods beginning after December 15, 2017. Interest income earned on financial instruments is outside of the scope of the update, and as a result the impact of the update is limited to certain components of noninterest income. Management does not expect the requirements of this update to have a material impact on the Company’s financial position, results of operations or cash flows and expects that the most significant impact will be the disaggregated disclosure of certain components of noninterest income. While certain implementation issues relevant to our industry are still pending resolution, such as the applicability to interchange revenues, our preliminary conclusions reached as to the application of this new guidance are not expected to be significantly affected. We will continue to evaluate any impact, including changes to related disclosures, as additional guidance is issued and as our internal assessment progresses. In January 2016, the FASB released accounting standards update 2016-01 Recognition and Measurement of Financial Assets and Liabilities. The main provisions of the update are to eliminate the available for sale classification of accounting for equity securities and to adjust the fair value disclosures for financial instruments carried at amortized costs such that the disclosed fair values represent an exit price as opposed to an entry price. The provisions of this update will require that equity securities be carried at fair market value on the balance sheet and any periodic changes in value will be adjustments to the income statement. A practical expedient is provided for equity securities without a readily determinable fair value, such that these securities can be carried at cost less any impairment. The provisions of this update become effective for interim and annual periods beginning after December 15, 2017. The disclosure of fair value of the loan portfolio will be impacted as the fair value will be calculated using an exit price. Management does not expect the requirements of this update to have a material impact on the Company’s financial position, results of operations or cash flows.  In February 2016, the FASB issued accounting standards update 2016-02 Leases. The update requires all leases, with the exception of short-term leases that have contractual terms of no greater than one year, to be recorded on the balance sheet. Under the provisions of the update, leases classified as operating will be reflected on the balance sheet with the recognition of both a right-of-use asset and a lease liability. Under the update, a distinction will exist between finance and operating type leases and the rules for determining which classification a lease will fall into are similar to existing rules. For public business entities, the amendments of this update are effective for interim and annual periods beginning after December 15, 2018. The update requires a modified retrospective transition under which comparative balance sheets from the earliest historical period presented will be revised to reflect what the financials would have looked like were the provisions of the update applied consistently in all prior periods. Management is in the process of evaluating the impacts of the update on the Company’s financial position and does not expect the requirements of the update to have a material impact on the Company’s financial position, results of operations or cash flows. Based on leases outstanding at June 30, 2017, we anticipate total assets and total liabilities will increase between $8,200,000 and $9,800,000 as the result of additional leases being recognized on our balance sheet. Decisions to repurchase, modify, or renew leases prior to the implementation date will impact the results of the Company’s final analysis.  In June 2016, the FASB issued accounting standards update 2016-13 Financial Instruments - Credit Losses, commonly referred to as “CECL”. The provisions of the update eliminate the probable initial recognition threshold under current GAAP which requires reserves to be based on an incurred loss methodology. Under CECL, reserves required for financial assets measured at amortized cost will reflect an organization’s estimate of all expected credit losses over the contractual term of the financial asset and thereby require the use of reasonable and supportable forecasts to estimate future credit losses. Because CECL encompasses all financial assets carried at amortized cost, the requirement that reserves be established based on an organization’s reasonable and supportable estimate of expected credit losses extends to held to maturity (“HTM”) debt securities. Under the provisions of the update, credit losses recognized on available for sale (“AFS”) debt securities will be presented as an allowance as opposed to a write-down. In addition, CECL will modify the accounting for purchased loans, with credit deterioration since origination, so that reserves are established at the date of acquisition for purchased loans. Under current GAAP, a purchased loan’s contractual balance is adjusted to fair value through a credit discount and no reserve is recorded on the purchased loan upon acquisition. Since, reserves will be established for purchased loans at the time of acquisition under CECL, the accounting for purchased loans is made more comparable to the accounting for originated loans. Finally, increased disclosure requirements under CECL require organizations to present the currently required credit quality disclosures disaggregated by the year of origination or vintage. The FASB expects that the evaluation of underwriting standards and credit quality trends by financial statement users will be enhanced with the additional vintage disclosures. For public business entities that are SEC filers, the amendments of the update will become effective beginning January 1, 2020. The Company has formed a cross-functional committee that is assessing our data and system needs and has begun initial discussions with an external vendor regarding the development of a CECL-compliant model and the gathering of the requisite data. Management expects to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the first reporting period in which the new standard is effective, but cannot yet estimate the magnitude of the one-time adjustment or the overall impact of the new guidance on the Company’s financial position, results of operations or cash flows.  In August 2016, the FASB issued accounting standards update 2016-15, Statement of Cash Flows. This update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in this update are effective for fiscal years and interim periods beginning after December 15, 2017; however early adoption is permitted. The provisions of the update outline the appropriate classification of debt extinguishment costs, repayment of debt instruments with insignificant coupons, contingent consideration payments made subsequent to a business combination, insurance proceeds, premiums and settlements on bank-owned life insurance policies, distributions from equity method investees, beneficial interest in securitizations and the appropriate classification of payments and receipts that contain aspects of multiple classes of cash flows. Management does not expect the update to materially impact the Company’s statement of cash flows, although the classification of certain items could shift relative to past presentation. For example, in 2014 the Company classified a $5.5 million prepayment penalty on debt extinguishment in Operating, under the provisions of the update if that penalty were incurred in 2018, it would be included in Financing.  In January 2017, the FASB issued accounting standards update 2017-04, Simplifying the Test for Goodwill Impairment. The provisions of the update eliminate the existing second step of the goodwill impairment test which provides for the allocation of reporting unit fair value among existing assets and liabilities, with the net remaining amount representing the implied fair value of goodwill. In replacement of the existing goodwill impairment rule, the update will provide that impairment should be recognized as the excess of any of the reporting unit’s goodwill over the fair value of the reporting unit. Under the provisions of this update, the amount of the impairment is limited to the carrying value of the reporting unit’s goodwill. For public business entities that are SEC filers, the amendments of the update will become effective in fiscal years beginning after December 15, 2019. Management does not expect the requirements of this update to have a material impact on the Company’s financial position, results of operations or cash flows.  In March 2017, the FASB issued accounting standards update 2017-08, Premium Amortization on Purchased Callable Debt Securities. The provisions of the update require premiums recognized upon the purchase of callable debt securities to be amortized to the earliest call date in order to avoid losses recognized upon call. For public business entities that are SEC filers, the amendments of the update will become effective in fiscal years beginning after December 15, 2018. Management does not expect the requirements of this update to have a material impact on the Company’s financial position, results of operations or cash flows.
