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, 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 subsidiaries Private Capital Management, LLC (“PCM”) and Cherry Hills Investment Advisors, Inc. (“CHIA”), provide s wealth management services, including private banking, investment management and trust services. 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 generally 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.  (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, 201 5 .  (b) 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.  (c) Loans and Loan Commitments  The Company extends commercial, real estate, agricultural and consumer loans to customers. A substantial portion of the loan portfolio consists of commercial and real estate loans made to borrowers located throughout the Front Range of Colorado. The ability of the Company’s borrowers to honor their contracts is generally dependent upon the real estate and general economic conditions prevailing in Colorado, among other factors.  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 and any deferred fees or costs. 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.  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 a ssured.  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.  (d) 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 the nature and volume of the loan portfolio, adverse situations that may affect borrowers’ ability to repay, estimated val ue 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 uncollectible 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 discounted by 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 calculat ing 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 h istorical 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.  ( e ) Other Intangible Assets  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 s ervicing 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. As of June 30, 2016 , the Company had recognized two customer relationship intangible assets as a result of the acquisitions of PCM on July 31, 2012 and CHIA on July 16, 2014.  ( f ) 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.  ( g ) 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, 2016 , 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 14 , 2019. Compensation cost related to the performance stock awards is recognized based on an evaluation of financial performance in comparison to established criteria. Should expectations of future financial performance change, the amount of expense recognized in future periods could be impacted.  ( h ) Stock Repurchase Plan  On February 2 , 201 6 , 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. The repurchase program had been scheduled to expire 12 months from the date of its announcement and, as extended, the program is scheduled to expire on April 2, 201 7 . 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.  ( i ) 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. In assessing the Company’s likelihood of realizing deferred tax assets, management evaluates both positive and negative evidence, including the existence of any cumulative losses in the current year and the prior two years, the amount of taxes paid in available carry-back years, forecasts of future income, taking into account app licable tax planning strategies and assessments of current and future economic and business conditions. Management performs this analysis quarterly and adjusts as necessary. At June 30, 2016 and December 31, 201 5 , the Company had a net deferred tax asset of $6,694,000 and $7,912,000 , respectively, which includes the deferred tax asset associated with the net unrealized loss 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, 2016, 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, 2016 or December 31, 201 5 .  The Company and the Bank are subject to U.S. federal income tax and state of Colorado income tax. Generally, the Company is no longer subject to examination by Federal taxing authorities for years before 2012 and is no longer subject to examination by the State for years before 2011. 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, 2016 and December 31, 201 5 , the Company did no t have any amounts accrued for interest or penalties.  ( j ) 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,  2016 2015 2016 2015   Average common shares outstanding 21,242,520 21,070,199 21,213,706 21,053,853  Effect of dilutive unvested stock grants (1) 119,192 130,239 197,920 137,424  Average shares outstanding for calculated  diluted earnings per common share 21,361,712 21,200,438 21,411,626 21,191,277  _____________    (1) Unvested stock grants representing 554,591 shares at June 30, 2016 had a dilutive impact of 119,192 and 197,920 shares in the diluted earnings per share calculation for the three and six months ended June 30, 2016, respectively. Unvested stock grants representing 654,972 shares at June 30, 2015 had a dilutive impact of 130,239 and 137,424 shares in the diluted earnings per share calculation for the three and six months ended June 30, 2015, respectively.   ( k) Recently Issued Accounting Standards  Adoption of New Accounting Standards:  In September 2015 , the FASB issued accounting standards update 2015-16 Simplifying the Accounting for Measurement-Period Adjustments. The update requires acquirers to adjust provisional amounts identified during the measurement period in the reporting period in which the adjustments are determined, rather than retrospectively adjusting previously reported information. Additional disclosure of the impact of measurement period adjustments on current year earnings will also be required. For public business entities, the amendments of this update are effective for interim and annual periods beginning after December 15, 2015. T his update does not have a material impact on the Company’s financial position, results of operations or cash flows.  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 a n alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. T he amendments of the update are to be effective for public entities beginning with interim and annual reporting periods beginning after December 15, 2017. 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 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. 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 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 b eginning 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 results of operations or cash flows.  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. Currently, excess tax benefits or deficiencies impact stockholder’s equity directly to the extent there is a cumulative excess tax benefit. In the event that a tax deficiency has occurred during the reporting period and a cumulative excess tax benefit does not exist, the tax deficiency is recognized in income tax expense under current 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 a fter December 15, 2016 . The update requires a modified retrospective transition under which a cumulative effect to equity will be recognized in the period of adoption. Management is in the process of evaluating the impact of the update on the Company’s financial position, results of operations and cash flows.  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 o n 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 pu rchased loan upon acquisition. Since under CECL reserves will be established for purchased loans at the time of acquisition the accounting for purchased loans is made more comparable to the ac counting 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. Management is in the process of evaluating the impact of CECL on the Company’s financial position, results of operations and cash flows as wel l as its required disclosures.  ( l ) Reclassifications  Certain reclassifications of prior year balances have been made to conform to the current year presentation. These reclassifications had no impact on the Company’s consolidated financial position, results of operations or cash flows .

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, 2016 or December 31, 201 5 .  At June 30, 2016 , there were 18 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 five se curities 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. The decrease in the number of securities in an unrealized loss position in excess of 12 months from 43 securities at December 31, 2015 to 13 securities at June 30 , 2016 was primarily attributable to the timing of interest rate fluctuations. The total number of securities in an unrealized loss position decreased from 88 individual securities at December 31, 2015 to 18 securities at June 30, 2016 also as a result of the timing of interest rate fluctuations. At June 30, 2016 , 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 reasonably made available to it that would prompt the need for more frequent review. At June 30, 2016 and December 31, 201 5 , the Company’s unrated municipal bonds comprised approximately 11.4% and 13.8% , respectively, of the carrying value of the Company’s entire municipal bond portfolio. At June 30, 2016 , a revenue bond issued by the Colorado Health Facilities Authority with a book value of $24,115,000 accounted for 10.5% of total stockholders’ equity. This amortizing tax-exempt bond is secured by a pledge of revenues and a deed of trust from a local hospital and carries an interest rate of 4.75% and is scheduled to mature on December 1, 2031 . Utilizing the discounted cash flow method and an estimate of current market rates for similar bonds, management determined the estimated fair value of this bond as of June 30, 2016 and December 31, 201 5 was approximately equal to its par value. In addition to conducting its annual review of unrated municipal bonds, the most recent of which was completed in the fourth quarter 201 5 , management conducts a quarterly review of the hospital’s financial statements. T o date, t he bond has paid principal and interest in accordance with its contractual term s, including a partial redemption in 2013 in advance of the contractual repayment schedule. The hospital has evidenced sufficient cash flow to service the debt .  Certain mortgage backed securities with an aggregate market value of approximately $19,217,000 as of June 30, 2016 were pledged to secure overnight repurchase agreement borrowings. Fluctuations in the fair value of these securities, and or the fluctuation in customer repurchase agreement balances, may result in the need to pledge additional securities against these borrowings. Management monitors the Bank’s collateral position with respect to repurchase agreement borrowings on a daily basis. The Company also pledges certain securities to public deposits under the Colorado Public Deposit Protection Act and pledges securities as collateral for funding lines. At June 30, 2016, the Company’s total pledged securities were $120,824,000 .

Loans [Abstract]
Loans	(3) Loans  A summary of net loans held for investment by loan type at the dates indicated is as follows:      June 30, December 31,  2016 2015   (In thousands)  Commercial and residential real estate $ 1,428,397 $ 1,281,701  Construction 26,497 107,170  Commercial 336,069 323,552  Agricultural 11,035 9,294  Consumer 66,539 66,288  SBA 28,494 25,645  Other 1,111 631  Total gross loans 1,898,142 1,814,281  Deferred costs, net 401 255  Loans, held for investment, net 1,898,543 1,814,536  Less allowance for loan losses (23,050) (23,000)  Net loans, held for investment $ 1,875,493 $ 1,791,536  In the second quarter 2016 the Company purchased $22.7 million in pe rforming loans included in our R eal Estate portfolio segment. No loans were purchased in the first six months of 2015.  Activity in the allowance for loan losses for the period indicated is as follows:      Three Months Ended June 30, Six Months Ended June 30,  2016 2015 2016 2015   (In thousands)  Balance, beginning of period $ 23,025 $ 22,500 $ 23,000 $ 22,490  Provision for loan losses 10 113 26 90  Loans charged-off (57) (48) (359) (97)  Recoveries on loans previously  charged-off 72 285 383 367  Balance, end of period $ 23,050 $ 22,850 $ 23,050 $ 22,850  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 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.

For the three months ended June 30, 2016 and June 30, 2015, gross interest income that would have been recorded on nonaccrual loans, had the loans been current in accordance with their original terms, was approximately $57,000 and $175,000 respectively. 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. No cash-basis interest income was recognized in the first six months of 2015.

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 f acts, 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, 2016 Commercial & Residential Real Estate Construction Commercial Consumer Other Total  (In thousands)  Non-classified $ 1,408,284 $ 25,511 $ 334,427 $ 66,206 $ 38,744 $ 1,873,172  Substandard 20,113 986 1,642 333 1,896 24,970  Doubtful - - - - - -  Subtotal 1,428,397 26,497 336,069 66,539 40,640 1,898,142  Deferred costs, net 301 6 71 14 9 401  Loans, held for investment, net $ 1,428,698 $ 26,503 $ 336,140 $ 66,553 $ 40,649 $ 1,898,543      December 31, 2015 Commercial & Residential Real Estate Construction Commercial Consumer Other Total  (In thousands)  Non-classified $ 1,260,134 $ 106,184 $ 322,650 $ 65,365 $ 34,194 $ 1,788,527  Substandard 21,567 986 902 923 1,376 25,754  Doubtful - - - - - -  Subtotal 1,281,701 107,170 323,552 66,288 35,570 1,814,281  Deferred costs, net 180 15 46 9 5 255  Loans, held for investment, net $ 1,281,881 $ 107,185 $ 323,598 $ 66,297 $ 35,575 $ 1,814,536  The book balance of TDRs at June 30 , 2016 and December 31, 2015 was $ 22,594,000 and $ 22,391,000 , respectively. Management established approximately $ 290,000 and $ 276,000 in specific reserves with respect to these loans as of June 30 , 2016 and December 31, 201 5 , respectively. The Company had an additional $1,030,000 and $953,000 committed on loans classified as TDRs at June 30, 2016 and December 31, 201 5 , respectively.  During the three and six months ended June 30, 2016 , the term s 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. During the first six months of 2015 there were no modifications of loans designated as TDRs.  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 , 2016 or June 30, 2015 .

Borrowings [Abstract]
Borrowings	 (5) Borrowings  At June 30, 2016 , the Company’s outstanding borrowings were $ 261,600,000 as compared to $ 280,847,000 at December 31, 201 5 . These borrowings at June 30, 2016 consisted of $120,000,000 in term notes and $141,600,000 in advances on our line of credit, both with the Federal Home Loan Bank (the “FHLB”). At December 31, 2015, outstanding borrowings consisted of $95,000,000 of t erm note s and $185,847,000 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 0.54 % at June 30, 2016. The Company has four term notes with the FHLB. Two of the term notes have fixed interest rates, the first 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 and 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 $50,000,000 carries an interest rate of 0.63% and matures October 24, 2016 . The Company also has two variable rate term notes of $25,000,000 each that mature on August 5, 2016 and March 7, 2017 and have interest rates that reset quarterly , currently set as 0.74% and 0.88% , respectively. The next rate reset dates on the variable rate term notes are August 5 , 2016 and September 7, 2016.  The Company has an advance, pledge and security agreement with the FHLB and had pledged qualifying loans and securities in the amount of $ 478,170,000 at June 30 , 2016 and $ 454,748,000 at December 31, 2015. The maximum credit allowance for future borrowings, including term notes and advances on the line of credit, was $ 216,570,000 at June 30, 2016 and $ 173,901,000 at December 31, 201 5 .  In April 2016, the holding company entered into a credit agreement for a $10,000,000 secured line of credit with Wells Fargo Bank, National Association. The holding company’s stock in Guaranty Bank and Trust Company is pledged as collateral to the line of credit. The line of credit matures on March 17, 2017. Under the credit agreement, we elect a fixed or floating interest rate on each advance. As of June 30, 2016 no amounts had been borrowed on the Wells Fargo line of credit.

Subordinated Debentures And Trust Preferred Securities [Abstract]
Subordinated Debentures and Trust Preferred Securities	(6) Subordinated Debentures and Trust Preferred Securities  At both June 30 , 2016 and December 31, 2015 the balance of the Company’s outstanding subordinated debentures (the “ Debentures”) was $ 25,774,000 . As of June 30, 2016, the Company's D ebentures bore a weighted average cost of funds of 3.46% .  The Company’s Debentures were issued in two separate series. Each issuance has a maturity of 30 years from its date of issuance. The 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 D ebentures 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 D ebentures 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 .  As of June 30, 2016 , the Company was in compliance with all financial covenants of the D ebentures.  The Company had a ccrued, unpaid interest on its D ebentures of approximately $225,000 at June 3 0 , 2016 and approximately $208,000 at December 31, 201 5. Interest payable on D ebentures 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 D ebentures 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, 2016 , the full $ 25,000,000 of the TruPS qualified as Tier 1 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.  The following table summarizes the terms of each outstanding subor dinated debenture issuance at June 30, 2016 (dollars in thousands):    Date Issued Amount Maturity Date Call Date * Fixed or Variable Rate Adjuster Current Rate Next Rate Reset Date**   CenBank Trust III 4/8/2004 15,464 4/15/2034 10/15/2016 Variable LIBOR + 2.65 % 3.28 % 10/15/2016  Guaranty Capital Trust III 6/30/2003 10,310 7/7/2033 10/7/2016 Variable LIBOR + 3.10 % 3.73 % 10/7/2016 * Call date represents the earliest or next date the Company can call the debentures . ** On July 7, 201 6 , the rate on the Guaranty Capital Trust III subordinated debentures reset to 3.78% . On July 15, 2016, the rate on the CenBank Trust III subordinated debentures reset to 3.33% .

Commitments [Abstract]
Commitments	(7) 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, 2016 December 31, 2015   (In thousands)  Commitments to extend credit:  Variable $ 301,341 $ 307,463  Fixed 59,538 61,184  Total commitments to extend credit $ 360,879 $ 368,647   Standby letters of credit $ 9,702 $ 8,857  At June 30, 2016 , the rates on the fixed rate commitments to extend credit ranged from 1.95 % to 7.00 %.  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. Several of the commitments may expire without being 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 generally 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	 (8) 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 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).

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 li ke 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-inte rest 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  Th e fair values of the Company’s 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 immaterial.

Derivatives And Hedging Activities [Abstract]
Derivative And Hedging Activities	 (9) 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, 2016 and December 31, 201 5 :      Balance Fair Value  Sheet June 30, December 31,  Location 2016 2015   (In thousands)  Derivatives designated as hedging instruments  Assets:  Interest rate swaps Other assets $ - $ -  Liabilities:  Interest rate swaps Other liabilities $ 4,063 $ 2,558   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 3 0 , 201 6 , the Company had two forward-starting interest rate swaps with an aggregate notional amount of $50,000,000 that were designated as cash flow hedges associated with the Company’s forecasted variable-rate borrowings. T he first $25,000,000 swap bec ame effective in June 2015 at a fixed rate of 2.46% and matur es in June 2020. The second $25,000,000 swap bec a me effective in March 2016 at a fixed rate of 3.00% and matur es in March 2021.  Summary information about the interest-rate swaps designated as cash flow hedges as of June 30 , 2016 and December 31, 2015 is included in the table below:     June 30, 2016 December 31, 2015   (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 4.4 years 4.9 years  Unrealized gains (losses) $ (4,063) $ (2,558)   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 issuance s of FHLB advances. During the six months ended June 30 , 2016 and June 30, 2015 , 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 $1,041,000 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 comprehensiv e income and net income for the three and six months ended June 30, 2016 and June 30, 2015 :      Income Three Months Ended Six Months Ended  Interest Rate Swaps with Statement June 30, June 30,  Hedge Designation Location 2016 2015 2016 2015   (In thousands)  Gain or (loss) recognized in OCI on  derivative - net of tax Not applicable $ (316) $ 277 $ (1,198) $ (297)  (Gain) or loss reclassified from  accumulated OCI into income  (effective portion) - net of tax Interest expense 163 - 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 o f its derivative counterparties and as of June 30, 2016 had posted $4,733,000 against its obligations under these agreements. If the Company had breached any of these provisions at June 30, 2016 , it could have been required to settle its obligations under the agreements at the termination value.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	 (10) 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 under the terms described in each of the plans.  S tock-based compensation awards issuable under either plan include 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 either 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, 2016 , there were 172,769 and 381 ,822 outstanding awards under the 2015 Plan and the Incentive Plan , respectively . As of June 30, 2016, there were 7 48,469 shares remaining available for grant under the 2015 Plan. Although the Incentive Plan expired by its terms on April 4, 2015, awards previously granted under the Incentive Plan remain outstanding in accordance with their terms.  Of the 554,591 shares represented by unvested awards at June 30 , 2016 , approximately 532 ,000 shares are expected to vest. At June 30 , 2016 the re were 319,005 shares of restricted stock outstanding that were subject to a performance condition. As of June 30, 2016, manage ment expects that approximately 306,000 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 February 2014 through May 2016. The vesting of these performance shares is contingent upon the meeting of certain return on asset performance criteria . The performance-based shares awarded in 2014 , 2015 and 201 6 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 , 2016, management expected that all of the performance awards made in 2014, 2015 and 2016 will vest ( with the exception of e stimated forfeitures), which is consistent with the level of expense currently being recognized over the vesting period. Should this expectation change, the accrual 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, 2016 is presented in the table below:     Shares Weighted Average Fair Value on Award Date  Unearned at January 1, 2016 590,755 $ 12.88  Awarded 165,504 15.33  Forfeited (12,569) 11.04  Vested (189,099) 11.21  Unearned at June 30, 2016 554,591 $ 14.22  The Company recognized $ 1,566,000 and $ 1,393,000 in stock-based compensation expense for services rendered for the six months ended June 30, 2016 and June 30, 2015 , respectively. The total income tax benefit recognized for share-based compensation arrangements was $595,000 and $530,000 for the six months ended June 30, 2016 and June 30, 2015 , respectively. The grant date fair value of restricted stock awards granted in the six months ended June 30 , 2016 and June 30, 2015 was $2,538,000 and $2,327,000 , respectively . The fair value of awards that vested in the six months ended June 30 , 2016 and June 30, 2015 was approximately $2,966,000 and $1,304,000 , respectively. At June 30, 2016 , compensation cost of $ 4,924,000 related to unvested awards not yet recognized is expected to be recognized over a weighted-average period of 1.9 years .

Contingencies [Abstract]
Contingencies	(1 2 ) Contingencies  The Company and the Bank are defendants, from time-to-time, in legal actions at various points of the legal process, including appeals, a rising 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.  On May 20, 2016, a putative stockholder class action lawsuit (the “Merger Litigation”), was filed against the Company and the individual members of Company’s board of directors in connection with the Company entering into the Agreement and Plan of Reorganization (the “Merger Agreement”). The action, Sciabacucchi v. Cordes et al. , Case No. 16cv31793, was filed in Colorado District Court, Denver County.  The Merger Litigation alleges that the members of the Company’s board of directors breached their fiduciary duties owed to the Company’s stockholders by causing a materially incomplete registration statement to be filed. The plaintiff in the Merger Litigation generally seeks, among other things, declaratory and injunctive relief concerning the alleged breach of fiduciary duties, injunctive relief prohibiting consummation of the merger and attorneys’ fees and costs, and other further relief.  On July 5, 2016, the parties to the merger litigation entered into a Memorandum of Agreement providing that, among other things: (1) the Company will make specified additional disclosures in the joint proxy statement/prospectus filed in connection with the Merger; (2) the merger litigation is stayed; and (3) the parties will enter into a stipulation providing for certification of a class for settlement purposes and a class release. The joint proxy statement/prospectus filing filed on July 19, 2016, included these specific additional disclosures. The proposed settlement is subject to, among other things, approval of the District Court, City and County of Denver, Colorado. Under the terms of the proposed settlement, following final court approval, the action will be dismissed with prejudice. There can be no assurances, however, that the parties will ultimately enter into a stipulation of settlement or that court approval of the settlement will be obtained. The proposed settlement may be terminated if any of the conditions to the proposed settlement are not met.  On the Company’s Form 10-Q as of March 31, 2016, the Company disclosed that a $1.85 million fraudulent, foreign wire transfer was initiated due to a compromise of a corporate customer account. In July 2016, the Company and the Company’s insurance carrier recovered all of the funds.

Business Combination	(1 3 ) Business Combination  On March 16, 2016, the Company entered into an Agreement and Plan of Reorganization (the “Merger Agreement”) with Home State Bancorp (“Home State”), parent company of Home State Bank, a Colorado state chartered bank headquartered in Loveland, Colorado (“Home State Bank”). The Merger Agreement provides that, subject to the terms and conditions set forth in the Merger Agreement, Home State will be merged with and into the Company, with the Company continuing as the surviving corporation. The Merger Agreement also provides that following the m erger , Home State Bank will be merged with and into the Bank, with the Bank continuing as the surviving bank . As of March 31, 2016, the pro forma combined Company would have approximately $3.3 billion in total assets and $2.5 billion in total deposits. The transaction is expected to close during the third quarter 2016, pending stockholder approval. The transaction will be accounted for using the acquisition method of accounting which requires that the assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date.

Use of Estimates	(b) 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	 (c) Loans and Loan Commitments  The Company extends commercial, real estate, agricultural and consumer loans to customers. A substantial portion of the loan portfolio consists of commercial and real estate loans made to borrowers located throughout the Front Range of Colorado. The ability of the Company’s borrowers to honor their contracts is generally dependent upon the real estate and general economic conditions prevailing in Colorado, among other factors.  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 and any deferred fees or costs. 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.  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 a ssured.  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	(d) 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 the nature and volume of the loan portfolio, adverse situations that may affect borrowers’ ability to repay, estimated val ue 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 uncollectible 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 discounted by 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 calculat ing 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 h istorical 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. 
Other Intangible Assets	( e ) Other Intangible Assets  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 s ervicing 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. As of June 30, 2016 , the Company had recognized two customer relationship intangible assets as a result of the acquisitions of PCM on July 31, 2012 and CHIA on July 16, 2014. 
Derivative Instruments	( f ) 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	 ( g ) 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, 2016 , 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 14 , 2019. Compensation cost related to the performance stock awards is recognized based on an evaluation of financial performance in comparison to established criteria. Should expectations of future financial performance change, the amount of expense recognized in future periods could be impacted. 
Stock Repurchase Plan	( h ) Stock Repurchase Plan  On February 2 , 201 6 , 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. The repurchase program had been scheduled to expire 12 months from the date of its announcement and, as extended, the program is scheduled to expire on April 2, 201 7 . 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	( i ) 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. In assessing the Company’s likelihood of realizing deferred tax assets, management evaluates both positive and negative evidence, including the existence of any cumulative losses in the current year and the prior two years, the amount of taxes paid in available carry-back years, forecasts of future income, taking into account app licable tax planning strategies and assessments of current and future economic and business conditions. Management performs this analysis quarterly and adjusts as necessary. At June 30, 2016 and December 31, 201 5 , the Company had a net deferred tax asset of $6,694,000 and $7,912,000 , respectively, which includes the deferred tax asset associated with the net unrealized loss 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, 2016, 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, 2016 or December 31, 201 5 .  The Company and the Bank are subject to U.S. federal income tax and state of Colorado income tax. Generally, the Company is no longer subject to examination by Federal taxing authorities for years before 2012 and is no longer subject to examination by the State for years before 2011. 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, 2016 and December 31, 201 5 , the Company did no t have any amounts accrued for interest or penalties. 
Earnings Per Common Share	( j ) 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,  2016 2015 2016 2015   Average common shares outstanding 21,242,520 21,070,199 21,213,706 21,053,853  Effect of dilutive unvested stock grants (1) 119,192 130,239 197,920 137,424  Average shares outstanding for calculated  diluted earnings per common share 21,361,712 21,200,438 21,411,626 21,191,277  _____________    (1) Unvested stock grants representing 554,591 shares at June 30, 2016 had a dilutive impact of 119,192 and 197,920 shares in the diluted earnings per share calculation for the three and six months ended June 30, 2016, respectively. Unvested stock grants representing 654,972 shares at June 30, 2015 had a dilutive impact of 130,239 and 137,424 shares in the diluted earnings per share calculation for the three and six months ended June 30, 2015, respectively. 
Recently Issued Accounting Standards	 ( k) Recently Issued Accounting Standards  Adoption of New Accounting Standards:  In September 2015 , the FASB issued accounting standards update 2015-16 Simplifying the Accounting for Measurement-Period Adjustments. The update requires acquirers to adjust provisional amounts identified during the measurement period in the reporting period in which the adjustments are determined, rather than retrospectively adjusting previously reported information. Additional disclosure of the impact of measurement period adjustments on current year earnings will also be required. For public business entities, the amendments of this update are effective for interim and annual periods beginning after December 15, 2015. T his update does not have a material impact on the Company’s financial position, results of operations or cash flows.  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 a n alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. T he amendments of the update are to be effective for public entities beginning with interim and annual reporting periods beginning after December 15, 2017. 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 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. 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 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 b eginning 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 results of operations or cash flows.  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. Currently, excess tax benefits or deficiencies impact stockholder’s equity directly to the extent there is a cumulative excess tax benefit. In the event that a tax deficiency has occurred during the reporting period and a cumulative excess tax benefit does not exist, the tax deficiency is recognized in income tax expense under current 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 a fter December 15, 2016 . The update requires a modified retrospective transition under which a cumulative effect to equity will be recognized in the period of adoption. Management is in the process of evaluating the impact of the update on the Company’s financial position, results of operations and cash flows.  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 o n 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 pu rchased loan upon acquisition. Since under CECL reserves will be established for purchased loans at the time of acquisition the accounting for purchased loans is made more comparable to the ac counting 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. Management is in the process of evaluating the impact of CECL on the Company’s financial position, results of operations and cash flows as wel l as its required disclosures. 
Reclassifications	( l ) Reclassifications  Certain reclassifications of prior year balances have been made to conform to the current year presentation. These reclassifications had no impact on the Company’s consolidated financial position, results of operations or cash flows .
