Basis of Presentation

Accounting Policies [Abstract]
Basis of Presentation	Note 1 Basis of Presentation National Bank Holdings Corporation ("NBHC" or the "Company") is a bank holding company that was incorporated in the State of Delaware in June 2009 with the intent to acquire and operate financial services franchises and other complementary businesses in targeted markets. The Company is headquartered immediately south of Denver, in Greenwood Village, Colorado, and its primary operations are conducted through its wholly owned subsidiary, NBH Bank (the "Bank"), a Colorado state-chartered bank and a member of the Federal Reserve System. The Company provides a variety of banking products to both commercial and consumer clients through a network of 91 banking centers located in Colorado, the greater Kansas City area and Texas, and through on-line and mobile banking products. The accompanying interim unaudited consolidated financial statements serve to update the National Bank Holdings Corporation Annual Report on Form 10-K for the year ended December 31, 2015 and include the accounts of the Company and the Bank and its wholly owned subsidiaries. The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and where applicable, with general practices in the banking industry or guidelines prescribed by bank regulatory agencies. However, they may not include all information and notes necessary to constitute a complete set of financial statements under GAAP applicable to annual periods and accordingly should be read in conjunction with the financial information contained in the Company's most recent Form 10-K. The unaudited consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results presented. All such adjustments are of a normal recurring nature. All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications of prior years' amounts are made whenever necessary to conform to current period presentation. During the first quarter of 2016, the Company updated the loan classifications in its allowance for loan losses model. Certain loan classifications within the consolidated financial statement disclosures have been updated to reflect this change. Refer to note 4 for further discussion. The prior period presentations have been reclassified to conform to the current period presentation. The results of operations for the interim period is not necessarily indicative of the results that may be expected for the full year or any other interim period. All amounts are in thousands, except share data, or as otherwise noted. GAAP requires management to make estimates that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosures of contingent assets and liabilities. By their nature, estimates are based on judgment and available information. Management has made significant estimates in certain areas, such as the amount and timing of expected cash flows from assets, the valuation of other real estate owned (“OREO”), the fair value adjustments on assets acquired and liabilities assumed, the valuation of core deposit intangible assets, the valuation of investment securities for other-than-temporary impairment (“OTTI”), the valuation of stock-based compensation, the fair values of financial instruments, the allowance for loan losses (“ALL”), and contingent liabilities. Because of the inherent uncertainties associated with any estimation process and future changes in market and economic conditions, it is possible that actual results could differ significantly from these estimates. The Company's significant accounting policies followed in the preparation of the unaudited consolidated financial statements are disclosed in note 2 of the audited financial statements and notes for the year ended December 31, 2015 and are contained in the Company's Annual Report on Form 10-K. There have not been any significant changes to the application of significant accounting policies since December 31, 2015, with the exception of the following: Loans held for sale— The Company enters into commitments to originate residential mortgage loans whereby the interest rate on the loan is determined prior to funding (i.e. interest rate lock commitments). Such interest rate lock commitments on mortgage loans to be sold in the secondary market are considered to be derivatives. To protect against the price risk inherent in residential mortgage loan commitments, the Company utilizes both "best efforts" and "mandatory delivery" forward loan sale commitments to mitigate the risk of potential increases or decreases in the values of loans that would result from the change in market rates for such loans. Under a "best efforts" contract, the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor and the investor commits to a price that it will purchase the loan from the Company only if the loan to the underlying borrower closes. As a result, the Company is not generally exposed to gains or losses on loans sold utilizing best efforts due to changes in underlying market interest rates between the time of the rate lock and loan sale. The market value of interest rate lock commitments and best efforts contracts are not readily ascertainable with precision because rate lock commitments and best efforts contracts are not actively traded. However, because of the high correlation between rate lock commitments and best efforts contracts offsetting market value changes, no gain or loss should occur on the interest rate lock commitments. Under a "mandatory delivery" contract, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. This typically happens after the loan to the underlying borrower closes. The Company manages the interest rate risk on interest rate lock commitments by entering into forward sale contracts of mortgage backed securities, whereby the Company obtains the right to deliver securities to investors in the future at a specified price. Such contracts are accounted for as derivatives and are recorded at fair value as derivative assets or liabilities. They are carried on the consolidated statements of financial condition within other assets or other liabilities and changes in fair value are recorded in other non-interest income within the consolidated statements of operations. The period of time between issuance of a loan commitment to the customer and closing of the loan to an investor generally ranges from 30 - 90 days under normal market conditions. The gross gains on loan sales are recognized based on new loan commitments with adjustment for price and pair-off activity. Commission expenses on loans held for sale are recognized based on loans closed. Income taxes — For the three and nine months ended September 30, 2016, the Company utilized the full year forecast method to calculated its interim income tax provision. For the three and nine months ended September 30, 2015, the Company utilized the discrete effective tax rate method, as allowed by Accounting Standards codification (“ASC”) 740-270-30-18, “Income Taxes-Interim Reporting,” to calculate its interim income tax provision. The discrete method is applied when the application of the estimated annual effective tax rate is impractical because it is not possible to reliably estimate the annual effective tax rate. The discrete method treats the year-to-date period as if it was the annual period and determines the income tax expense or benefit on that basis. The Company believed that, at that time, the use of this discrete method was more appropriate than the annual effective tax rate method as the estimated annual effective tax rate method was not reliable due to (1) the levels of tax-exempt income in relation to pre-tax income, (2) the impact of the warrant liability which is non-taxable and (3) the impact and variability of FDIC Indemnification amortization on pre-tax income. See further discussion in note 13.

Recent Accounting Pronouncement

Recent Accounting Pronouncements	9 Months Ended

Text Block [Abstract]
Recent Accounting Pronouncements	Note 2 Recent Accounting Pronouncements Revenue from Contracts with Customers —In May 2014, the FASB issued ASU 2014-09, " Revenue from Contracts with Customers ." This update supersedes revenue recognition requirements in ASC Topic 605, Revenue Recognition , including most industry-specific revenue recognition guidance in the FASB Accounting Standards Codification. The new guidance stipulates that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides specific steps that entities should apply in order to achieve this principle. The amendments are effective for interim and annual periods beginning after December 15, 2017, with early application permitted for interim and annual periods beginning after December 15, 2016. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. The Company is in the process of evaluating the impact of the ASU's adoption on the Company's consolidated financial statements. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities —In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825). ASU No. 2016-01 revises the classification and measurement of investments in certain equity investments and the presentation of certain fair value changes for certain financial liabilities measured at fair value. ASU No. 2016-01 requires the change in fair value of many equity investments to be recognized in net income. ASU No. 2016-01 is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. Adopting ASU No. 2016-01 may result in a cumulative effect adjustment to the consolidated statements of changes in shareholders’ equity as of the beginning of the year of adoption. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. Leases —In February 2016, the FASB issued ASU 2016-02, Leases. The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC Topic 840, Leases . The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statements. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. The Company is in the process of evaluating the impact of the ASU's adoption on the Company's consolidated financial statements . Improvements to Employee Share-Based Payment Accounting —In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which amends ASC Topic 718, Compensation – Stock Compensation . ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. Financial Instruments - Credit Losses —In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments . This update replaces the current incurred loss methodology for recognizing credit losses with a current expected credit loss model, which requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This amendment broadens the information that an entity must consider in developing its expected credit loss estimates. Additionally, the update amends the accounting for credit losses for available-for-sale debt securities and purchased financial assets with a more-than-insignificant amount of credit deterioration since origination. This update requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of a company’s loan portfolio. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption in fiscal years beginning after December 15, 2018 is permitted. The amendment requires the use of the modified retrospective approach for adoption. The Company is in the process of evaluating the impact of the ASU’s adoption on the Company’s consolidated financial statements. Statement of Cash Flows —In August 2016 , the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payment s. The update amends the guidance in ASC 230, Statement of Cash Flows , and clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows with the objective of reducing the existing diversity in practice related to eight specific cash flow items. The amendments in this update are effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of ASU 2016-15 to have a material impact on its financial statements.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Note 3 Investment Securities The Company’s investment securities portfolio is comprised of available-for-sale and held-to-maturity investment securities. These investment securities totaled $1.3 billion at September 30, 2016 and were comprised of $1.0 billion of available-for-sale securities and $0.3 billion of held-to-maturity securities. At December 31, 2015, investment securities totaled $1.6 billion and were comprised of $1.2 billion of available-for-sale securities and $0.4 billion of held-to-maturity securities. Available-for-sale At September 30, 2016 and December 31, 2015, the Company held $1.0 billion and $1.2 billion of available-for-sale investment securities, respectively. Available-for-sale investment securities are summarized as follows as of the dates indicated: September 30, 2016 Amortized Gross Gross cost unrealized gains unrealized losses Fair value Mortgage-backed securities (“MBS”): Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises $ $ $ — $ Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises Municipal securities — Other securities — — Total $ $ $ $ December 31, 2015 Amortized Gross Gross cost unrealized gains unrealized losses Fair value Mortgage-backed securities (“MBS”): Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises $ $ $ $ Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises Municipal securities — — Other securities — — Total $ $ $ $ At September 30, 2016 and December 31, 2015, mortgage-backed securities represented primarily all of the Company’s available-for-sale investment portfolio and all mortgage-backed securities were backed by government sponsored enterprises (“GSE”) collateral such as Federal Home Loan Mortgage Corporation (“FHLMC”) and Federal National Mortgage Association (“FNMA”), and the government sponsored agency Government National Mortgage Association (“GNMA”). The table below summarizes the unrealized losses as of the dates shown, along with the length of the impairment period: September 30, 2016 Less than 12 months 12 months or more Total Fair Unrealized Fair Unrealized Fair Unrealized value losses value losses value losses Mortgage-backed securities (“MBS”): Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises $ $ $ $ $ $ Total $ $ $ $ $ $ December 31, 2015 Less than 12 months 12 months or more Total Fair Unrealized Fair Unrealized Fair Unrealized value losses value losses value losses Mortgage-backed securities (“MBS”): Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises $ $ $ — $ — $ $ Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises Total $ $ $ $ $ $ Management evaluated all of the available-for-sale securities in an unrealized loss position and concluded that no OTTI existed at September 30, 2016 or December 31, 2015. The unrealized losses in the Company's investments issued or guaranteed by U.S. government agencies or sponsored enterprises at September 30, 2016 were caused by changes in interest rates. The portfolio included 51 securities, having an aggregate fair value of $504.3 million, which were in an unrealized loss position at September 30, 2016, compared to 66 securities, with a fair value of $752.7 million, at December 31, 2015. The Company has no intention to sell these securities before recovery of their amortized cost and believes it will not be required to sell the securities before the recovery of their amortized cost. Certain securities are pledged as collateral for public deposits, securities sold under agreements to repurchase, and to secure borrowing capacity at the Federal Reserve Bank and Federal Home Loan Bank (“FHLB”), if needed. The fair value of available-for-sale investment securities pledged as collateral totaled $262.4 million at September 30, 2016 and $335.8 million at December 31, 2015. The decrease in pledged available-for-sale investment securities was primarily attributable to a decrease in average deposit account balances and client repurchase account balances during the nine months ended September 30, 2016. Certain investment securities may also be pledged as collateral for the line of credit at the FHLB of Topeka; at September 30, 2016 and December 31, 2015, no securities were pledged for this purpose. Mortgage-backed securities do not have a single maturity date and actual maturities may differ from contractual maturities depending on the repayment characteristics and experience of the underlying financial instruments. The estimated weighted average life of the available-for-sale mortgage-backed securities portfolio was 3.0 years as of September 30, 2016 and 3.6 years as of December 31, 2015. This estimate is based on assumptions and actual results may differ. At September 30, 2016 and December 31, 2015, the duration of the total available-for-sale investment portfolio was 2.9 years and 3.4 years, respectively. As of September 30, 2016, municipal securities with an amortized cost and fair value of $3.7 million were due after one year through five years, while municipal securities with an amortized cost and fair value of $1.0 million were due after five years through ten years. Other securities of $0.4 million as of September 30, 2016, have no stated contractual maturity date. Held-to-maturity At September 30, 2016 and December 31, 2015, the Company held $355.4 million and $427.5 million of held-to-maturity investment securities, respectively. Held-to-maturity investment securities are summarized as follows as of the dates indicated: September 30, 2016 Gross Gross Amortized unrealized unrealized cost gains losses Fair value Mortgage-backed securities (“MBS”): Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises $ $ $ — $ Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises Total investment securities held-to-maturity $ $ $ $ December 31, 2015 Gross Gross Amortized unrealized unrealized cost gains losses Fair value Mortgage-backed securities (“MBS”): Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises $ $ $ $ Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises Total investment securities held-to-maturity $ $ $ $ The table below summarizes the unrealized losses as of the dates shown, along with the length of the impairment period: September 30, 2016 Less than 12 months 12 months or more Total Fair Unrealized Fair Unrealized Fair Unrealized Value Losses Value Losses Value Losses Mortgage-backed securities (“MBS”): Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises $ $ $ $ $ $ Total $ $ $ $ $ $ December 31, 2015 Less than 12 months 12 months or more Total Fair Unrealized Fair Unrealized Fair Unrealized Value Losses Value Losses Value Losses Mortgage-backed securities (“MBS”): Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises $ $ $ $ $ $ Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises Total $ $ $ $ $ $ The portfolio included five securities, having an aggregate fair value of $40.5 million, which were in an unrealized loss position at September 30, 2016, compared to twelve securities, with a fair value of $109.9 million, at December 31, 2015. Management evaluated all of the held-to-maturity securities in an unrealized loss position and concluded that no OTTI existed at September 30, 2016 or December 31, 2015. The unrealized losses in the Company's investments issued or guaranteed by U.S. government agencies or sponsored enterprises at September 30, 2016 were caused by changes in interest rates. The Company has no intention to sell these securities before recovery of their amortized cost and believes it will not be required to sell the securities before the recovery of their amortized cost. The carrying value of held-to-maturity investment securities pledged as collateral totaled $163.4 million and $156.5 million at September 30, 2016 and December 31, 2015, respectively. Actual maturities of mortgage-backed securities may differ from scheduled maturities depending on the repayment characteristics and experience of the underlying financial instruments. The estimated weighted average expected life of the held-to-maturity mortgage-backed securities portfolio as of September 30, 2016 and December 31, 2015 was 3.1 years and 3.7 years, respectively. This estimate is based on assumptions and actual results may differ. The duration of the total held-to-maturity investment portfolio was 2.9 years and 3.4 years as of September 30, 2016 and December 31, 2015, respectively.

Loans	Note 4 Loans The loan portfolio is comprised of loans originated by the Company and loans that were acquired in connection with the Company’s acquisitions. The table below shows the loan portfolio composition including carrying value by segment of loans accounted for under ASC Topic 310-30, Receivables—Loans and Debt Securities Acquired with Deteriorated Credit Quality, and loans not accounted for under this guidance, which includes our originated loans. The carrying value of loans is net of discounts, fees and costs on loans excluded from ASC 310-30 of $6.9 million and $8.1 million as of September 30, 2016 and December 31, 2015, respectively: September 30, 2016 ASC 310-30 loans Non 310-30 loans Total loans % of total Commercial $ $ $ Commercial real estate non-owner occupied Residential real estate Consumer Total $ $ $ December 31, 2015 ASC 310-30 loans Non 310-30 loans Total loans % of total Commercial $ $ $ Commercial real estate non-owner occupied Residential real estate Consumer Total $ $ $ Delinquency for loans excluded from ASC 310-30 is shown in the following tables at September 30, 2016 and December 31, 2015, respectively: Total Loans September 30, 2016 Greater Total Loans > 90 30-59 60-89 than 90 Non days past days past days past days past Total past 310-30 due and Non- due due due due Current loans still accruing accrual Loans excluded from ASC 310-30: Commercial: Commercial and industrial $ $ $ $ $ $ $ $ Owner occupied commercial real estate — Agriculture — — Energy — — Total Commercial Commercial real estate non-owner occupied: Construction — — — — Acquisition/development — — — — — — Multifamily — — — — — — Non-owner occupied — — — Total commercial real estate — — Residential real estate: Senior lien Junior lien — Total residential real estate Consumer Total loans excluded from ASC 310-30 $ $ $ $ $ $ $ $ Total Loans December 31, 2015 Greater Total Loans > 90 30-59 60-89 than 90 Non days past days past days past days past Total past 310-30 due and Non- due due due due Current loans still accruing accrual Loans excluded from ASC 310-30: Commercial: Commercial and industrial $ $ $ $ $ $ $ — $ Owner occupied commercial real estate — Agriculture — Energy — — Total Commercial — Commercial real estate non-owner occupied: Construction — — Acquisition/development — — — — — — Multifamily — — Non-owner occupied — Total commercial real estate — Residential real estate: Senior lien Junior lien Total residential real estate Consumer Total loans excluded from ASC 310-30 $ $ $ $ $ $ $ $ Loans are considered past due or delinquent when the contractual principal or interest due in accordance with the terms of the loan agreement remains unpaid after the due date of the scheduled payment. Pooled loans accounted for under ASC 310-30 that are 90 days or more past due and still accreting are generally considered to be performing and are included in loans 90 days or more past due and still accruing. Non-accrual loans include troubled debt restructurings on non-accrual status. Non-accrual loans excluded from the scope of ASC 310-30 totaled $22.5 million at September 30, 2016, decreasing $3.2 million, or 12.4%, from $25.6 million at December 31, 2015. The change was driven by decreases of $2.7 million in the commercial and industrial sector due to charge-offs throughout the year and other net decreases of $1.8 million, offset by a net increase of $1.3 million in the energy sector at September 30, 2016. Credit exposure for all loans as determined by the Company’s internal risk rating system was as follows as of September 30, 2016 and December 31, 2015, respectively: Total Loans September 30, 2016 Special Pass mention Substandard Doubtful Total Loans excluded from ASC 310-30: Commercial: Commercial and industrial $ $ $ $ — $ Owner occupied commercial real estate — Agriculture — Energy Total Commercial Commercial real estate non-owner occupied: Construction — Acquisition/development — — Multifamily — — Non-owner occupied — Total commercial real estate — Residential real estate: Senior lien — Junior lien — Total residential real estate — Consumer — Total loans excluded from ASC 310-30 $ $ $ $ $ Loans accounted for under ASC 310-30: Commercial $ $ $ $ — $ Commercial real estate non-owner occupied Residential real estate — Consumer — Total loans accounted for under ASC 310-30 $ $ $ $ $ Total loans $ $ $ $ $ Total Loans December 31, 2015 Special Pass mention Substandard Doubtful Total Loans excluded from ASC 310-30: Commercial: Commercial and industrial $ $ $ $ $ Owner occupied commercial real estate — Agriculture — Energy Total Commercial Commercial real estate non-owner occupied: Construction — Acquisition/development — — Multifamily — — Non-owner occupied Total commercial real estate Residential real estate: Senior lien Junior lien — Total residential real estate Consumer — Total loans excluded from ASC 310-30 $ $ $ $ $ Loans accounted for under ASC 310-30: Commercial $ $ $ $ — $ Commercial real estate non-owner occupied Residential real estate — Consumer — Total loans accounted for under ASC 310-30 $ $ $ $ $ Total loans $ $ $ $ $ The Company's energy sector substandard and doubtful loans excluded from ASC 310-30 totaled $13.3 million and $18.2 million at September 30, 2016 and December 31, 2015, respectively. The decrease of $4.9 million was driven primarily by two loan relationships with balances of $11.4 million at December 31, 2015, which were charged-off during the second and third quarter of 2016, offset by increases of $6.3 million related to two loan relationships placed on non-accrual during 2016. Non 310-30 special mention loans within the commercial and industrial sector increased from December 31, 2015, largely due to downgrades to special mention of three loan relationships totaling $15.8 million, offset by a downgrade from special mention to substandard for one loan relationship of $4.1 million during the nine months ended September 30, 2016. Non 310-30 special mention loans within the agriculture sector increased from December 31, 2015, largely due to one loan relationship downgraded to special mention during the third quarter of 2016 totaling $9.0 million, offset by a downgrade to substandard of one loan relationship totaling $1.6 million at December 31, 2015. Impaired Loans Loans are considered to be impaired when it is probable that the Company will not be able to collect all amounts due in accordance with the contractual terms of the loan agreement. Impaired loans are comprised of loans excluded from ASC 310-30 on non-accrual status, loans in bankruptcy, and troubled debt restructurings (“TDRs”) described below. If a specific allowance is warranted based on the borrower’s overall financial condition, the specific allowance is calculated based on discounted cash flows using the loan’s initial contractual effective interest rate or the fair value of the collateral less selling costs for collateral dependent loans. At September 30, 2016, the Company measured $24.9 million of impaired loans based on the fair value of the collateral less selling costs and $2.3 million of impaired loans using discounted cash flows and the loan’s initial contractual effective interest rate. Impaired loans totaling $8.2 million that individually were less than $250 thousand each, were measured through the general ALL reserves due to their relatively small size. At September 30, 2016 and December 31, 2015, the Company’s recorded investments in impaired loans were $35.4 million and $37.4 million, respectively. Impaired loans at September 30, 2016 were primarily comprised of eight relationships totaling $22.5 million. Three of the relationships were in the energy sector, four of the relationships were in the commercial and industrial sector, and one relationship was in the agricultural sector. The three energy relationships were on non-accrual status at September 30, 2016. Impaired loans had a collective related allowance for loan losses allocated to them of $1.5 million and $4.4 million at September 30, 2016 and December 31, 2015, respectively. Additional information regarding impaired loans at September 30, 2016 and December 31, 2015 is set forth in the table below: Impaired Loans September 30, 2016 December 31, 2015 Allowance Allowance Unpaid for loan Unpaid for loan principal Recorded losses principal Recorded losses balance investment allocated balance investment allocated With no related allowance recorded: Commercial: Commercial and industrial $ $ $ — $ $ $ — Owner occupied commercial real estate — — Agriculture — — Energy — — Total commercial — — Commercial real estate non-owner occupied: Construction — — — — Acquisition/development — — — — — — Multifamily — — — — — — Non-owner occupied — — Total commercial real estate — — Residential real estate: Senior lien — — Junior lien — — Total residential real estate — — Consumer — — — — Total impaired loans with no related allowance recorded $ $ $ — $ $ $ — With a related allowance recorded: Commercial: Commercial and industrial $ $ $ — $ $ $ Owner occupied commercial real estate Agriculture — Energy Total commercial Commercial real estate non-owner occupied: Construction — — — — — — Acquisition/development — — — — — — Multifamily — — Non-owner occupied Total commercial real estate Residential real estate: Senior lien Junior lien Total residential real estate Consumer Total impaired loans with a related allowance recorded $ $ $ $ $ $ Total impaired loans $ $ $ $ $ $ The table below shows additional information regarding the average recorded investment and interest income recognized on impaired loans for the periods presented: For the three months ended September 30, 2016 September 30, 2015 Average Interest Average Interest With no related allowance recorded: Commercial: Commercial and industrial $ $ $ $ Owner occupied commercial real estate Agriculture — — Energy — — Total Commercial Commercial real estate non-owner occupied: Construction — — — — Acquisition/development — — — — Multifamily — — — — Non-owner occupied — Total commercial real estate — Residential real estate: Senior lien Junior lien — — — Total residential real estate Consumer — — — Total impaired loans with no related allowance recorded $ $ $ $ With a related allowance recorded: Commercial: Commercial and industrial $ $ — $ $ — Owner occupied commercial real estate Agriculture Energy — — Total Commercial Commercial real estate non-owner occupied: Construction — — — — Acquisition/development — — — — Multifamily — — Non-owner occupied Total commercial real estate Residential real estate: Senior lien Junior lien Total residential real estate Consumer — — Total impaired loans with a related allowance recorded $ $ $ $ Total impaired loans $ $ $ $ For the nine months ended September 30, 2016 September 30, 2015 Average Interest Average Interest With no related allowance recorded: Commercial: Commercial and industrial $ $ $ $ Owner occupied commercial real estate Agriculture — — Energy — — Total Commercial Commercial real estate non-owner occupied: Construction — — — — Acquisition/development — — — — Multifamily — — — — Non-owner occupied — Total commercial real estate — Residential real estate: Senior lien Junior lien — — Total residential real estate Consumer — — — Total impaired loans with no related allowance recorded $ $ $ $ With a related allowance recorded: Commercial: Commercial and industrial $ $ — $ $ Owner occupied commercial real estate Agriculture Energy — Total Commercial Commercial real estate non-owner occupied: Construction — — — — Acquisition/development — — — — Multifamily Non-owner occupied Total commercial real estate Residential real estate: Senior lien Junior lien Total residential real estate Consumer — Total impaired loans with a related allowance recorded $ $ $ $ Total impaired loans $ $ $ $ Interest income recognized on impaired loans noted in the table above primarily represents interest earned on accruing troubled debt restructurings. Interest income recognized on impaired loans using the cash-basis method of accounting during the three months ended September 30, 2016 and 2015 was $0.1 million and $0.4 million, respectively. Interest income recognized on impaired loans using the cash-basis method of accounting during the nine months ended September 30, 2016 and 2015 was $0.4 million and $1.1 million, respectively. Troubled debt restructurings It is the Company’s policy to review each prospective credit in order to determine the appropriateness and the adequacy of security or collateral prior to making a loan. In the event of borrower default, the Company seeks recovery in compliance with lending laws, the respective loan agreements, and credit monitoring and remediation procedures that may include restructuring a loan to provide a concession by the Company to the borrower from their original terms due to borrower financial difficulties in order to facilitate repayment. Additionally, if a borrower’s repayment obligation has been discharged by a court, and that debt has not been reaffirmed by the borrower, regardless of past due status, the loan is considered to be a TDR. At September 30, 2016 and December 31, 2015, the Company had $8.8 million and $8.4 million, respectively, of accruing TDRs that had been restructured from the original terms in order to facilitate repayment. Non-accruing TDRs at September 30, 2016 and December 31, 2015 totaled $12.0 million and $17.8 million, respectively. During the nine months ended September 30, 2016, the Company restructured 15 loans with a recorded investment of $12.4 million to facilitate repayment. Substantially all of the loan modifications were a reduction of the principal payment, a reduction in interest rate, or an extension of term. Loan modifications to loans accounted for under ASC 310-30 are not considered TDRs. The table below provides additional information related to accruing TDRs at September 30, 2016 and December 31, 2015: Accruing TDRs September 30, 2016 Recorded Average year-to-date Unpaid Unfunded commitments investment recorded investments principal balance to fund TDRs Commercial $ $ $ $ — Commercial real estate non-owner occupied — Residential real estate Consumer — Total $ $ $ $ Accruing TDRs December 31, 2015 Recorded Average year-to-date Unpaid Unfunded commitments investment recorded investments principal balance to fund TDRs Commercial $ $ $ $ Commercial real estate non-owner occupied — Residential real estate Consumer — Total $ $ $ $ The following table summarizes the Company’s carrying value of non-accrual TDRs as of September 30, 2016 and December 31, 2015: Non - Accruing TDRs September 30, 2016 December 31, 2015 Commercial $ $ Commercial real estate non-owner occupied — Residential real estate Consumer Total $ $ Accrual of interest is resumed on loans that were on non-accrual only after the loan has performed sufficiently. The Company had three TDRs that were modified within the past twelve months and had defaulted on their restructured terms during the three months ended September 30, 2016, and five TDRs that were modified within the past twelve months and had defaulted on their restructured terms during the nine months ended September 30, 2016. The defaulted TDRs consisted of one energy sector loan totaling $3.0 million, three residential loans totaling $0.4 million, and one commercial real estate loan totaling $0.2 million. The allowance for loan losses related to troubled debt restructurings on non-accrual status is determined by individual evaluation, including collateral adequacy, using the same process as loans on non-accrual status which are not classified as troubled debt restructurings. During the three and nine months ended September 30, 2015, the Company had no TDRs that had been modified within the past 12 months that defaulted on their restructured terms. Loans accounted for under ASC Topic 310-30 Loan pools accounted for under ASC Topic 310-30 are periodically remeasured to determine expected future cash flows. In determining the expected cash flows, the timing of cash flows and prepayment assumptions for smaller homogeneous loans are based on statistical models that take into account factors such as the loan interest rate, credit profile of the borrowers, the years in which the loans were originated, and whether the loans are fixed or variable rate loans. Prepayments may be assumed on loans if circumstances specific to that loan warrant a prepayment assumption. The re-measurement of loans accounted for under ASC 310-30 resulted in the following changes in the carrying amount of accretable yield during the nine months ended September 30, 2016 and 2015: September 30, 2016 September 30, 2015 Accretable yield beginning balance $ $ Reclassification from non-accretable difference Reclassification to non-accretable difference Accretion Accretable yield ending balance $ $ Below is the composition of the net book value for loans accounted for under ASC 310-30 at September 30, 2016 and December 31, 2015: September 30, 2016 December 31, 2015 Contractual cash flows $ $ Non-accretable difference Accretable yield Loans accounted for under ASC 310-30 $ $

Within the segments, the portfolio was further disaggregated into classes of loans with similar attributes and risk characteristics for purposes of applying loss ratios and determining applicable subjective adjustments to the ALL. The application of subjective adjustments was based upon qualitative risk factors, including economic trends and conditions, industry conditions, asset quality, loss trends, lending management, portfolio growth and loan review/internal audit results. During the first quarter of 2016, the Company updated the loan classifications in its allowance for loan losses model to include owner occupied commercial real estate and agriculture within the commercial loan segment and present energy as its own loan class within the commercial segment. The prior year presentation has been reclassified to conform to the current year presentation. The Company had $17.4 million and $21.4 million net charge-offs of non 310-30 loans during the three and nine months ended September 30, 2016, respectively. Management's evaluation resulted in a provision for loan losses on the non 310-30 loans of $5.3 million and $23.2 million during the three and nine months ended September 30, 2016, respectively. Provision for the three months ended September 30, 2016 was driven by loan growth and an increase in the energy sector provision of $3.9 million, primarily driven by one midstream sector client. The nine months ended September 30, 2016 provision was driven by a $19.0 million increase in the energy sector provision. During the nine months ended September 30, 2016, the Company re-estimated the expected cash flows of the loan pools accounted for under ASC 310-30. The re-measurement resulted in a net provision of $18 thousand and a net recoupment of $787 thousand for the three and nine months ended September 30, 2016, respectively. The net provision and net recoupment was comprised primarily of a provision of $27 thousand in the commercial segment, offset by recoupments of $12 thousand in the consumer segment during the three months ended September 30, 2016, and comprised primarily of a recoupment of $759 thousand in the commercial segment for the nine months ended September 30, 2016, respectively. The Company had $0.1 million and $0.8 million net charge offs of non ASC 310-30 loans during the three and nine months ended September 30, 2015, respectively. Management’s evaluation resulted in a provision for loan losses on the non 310-30 loans of $3.6 million and $6.9 million, respectively, during the three and nine months ended September 30, 2015. During the nine months ended September 30, 2015, the Company re-estimated the expected cash flows of the loan pools accounted for under ASC 310-30 utilizing the same cash flow methodology used at the time of acquisition. The re-measurement resulted in a net provision of $110 thousand and $168 thousand for the three and nine months ended September 30, 2015, which were comprised primarily of provision of $148 thousand in the commercial segment, offset by recoupments of $37 thousand in the non-owner occupied commercial real estate segment, during the three months ended September 30, 2015, and provision of $312 thousand in the commercial segment, offset by recoupment of $133 thousand in the non-owner occupied commercial real estate segment, during the nine months ended September 30, 2015.

Banking and Thrift [Abstract]
Regulatory Capital	Note 8 Regulatory Capital As a bank holding company, the Company is subject to regulatory capital adequacy requirements implemented by the Federal Reserve. The federal banking agencies have risk-based capital adequacy regulations intended to provide a measure of capital adequacy that reflects the degree of risk associated with a banking organization’s operations. Under these regulations, assets are assigned to one of several risk categories, and nominal dollar amounts of assets and credit equivalent amounts of off-balance-sheet items are multiplied by a risk adjustment percentage for the category. The new Basel III rules, effective January 1, 2015, changed the components of regulatory capital and changed the way in which risk ratings are assigned to various categories of bank assets. Also, a new Tier I common risk-based ratio was defined. Under the Basel III requirements, at September 30, 2016, the Company and the Bank met all capital adequacy requirements and the Bank had regulatory capital ratios in excess of the levels established for well-capitalized institutions. In February 2016, the Bank received approval from the Colorado Division of Banking and the Federal Reserve Bank of Kansas City to permanently reduce the Bank's capital by $140.0 million. As a result, the Bank distributed $140.0 million cash to the Company in February 2016. At September 30, 2016 and December 31, 2015, the Bank met the requirement to be considered “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well-capitalized”, the Bank must maintain total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the table below.

Stock-based Compensation and Benefits	Note 9 Stock-based Compensation and Benefits The Company provides stock-based compensation in accordance with shareholder-approved plans. During the second quarter of 2014, shareholders approved the 2014 Omnibus Incentive Plan (the "2014 Plan"). The 2014 Plan replaces the NBH Holdings Corp. 2009 Equity Incentive Plan (the "Prior Plan"), pursuant to which the Company granted equity awards prior to the approval of the 2014 Plan. Pursuant to the 2014 Plan, the Compensation Committee of the Board of Directors has the authority to grant, from time to time, awards of stock options, stock appreciation rights, restricted stock, performance stock units, market-based stock units, other stock-based awards, or any combination thereof to eligible persons. As of September 30, 2016, the aggregate number of shares of Class A common stock available for issuance under the 2014 Plan is 5,097,434 shares. Any shares that are subject to stock options or stock appreciation rights under the 2014 Plan will be counted against the amount available for issuance as one share for every one share granted, and any shares that are subject to awards under the 2014 Plan other than stock options or stock appreciation rights will be counted against the amount available for issuance as 3.25 shares for every one share granted. The 2014 Plan provides for recycling of shares from both the Prior Plan and the 2014 Plan, the terms of which are further described in the Company's Proxy Statement for its 2014 Annual Meeting of Shareholders. To date, the Company has issued stock options, restricted stock, and performance stock units under the plans. The Compensation Committee sets the option exercise price at the time of grant, but in no case is the exercise price less than the fair market value of a share of stock at the date of grant. Stock options The Company issued stock options in accordance with the 2014 Plan during the nine months ended September 30, 2016. The options granted during the nine months ended September 30, 2016 are time-vesting over a 3-year period. The expense associated with the awarded stock options was measured at fair value using a Black-Scholes option-pricing model. The outstanding option awards vest on a graded basis over 1-4 years of continuous service and have 7-10 year contractual terms. The following table summarizes stock option activity for the nine months ended September 30, 2016: Weighted Average Weighted Remaining Average Contractual Aggregate Exercise Term in Intrinsic Options Price Years Value Outstanding at December 31, 2015 $ $ Granted Forfeited Surrendered Exercised Expired Outstanding at September 30, 2016 $ $ Options exercisable at September 30, 2016 $ $ Options expected to vest $ $ Stock option expense is included in salaries and benefits in the consolidated statements of operations and totaled $0.2 million for the three months ended September 30, 2016 and 2015, and $0.5 million for the nine months ended September 30, 2016 and 2015, respectively. At September 30, 2016, there was $0.7 million of total unrecognized compensation cost related to non-vested stock options granted under the plans. The cost is expected to be recognized over a weighted average period of 2.1 years. Restricted stock awards During the nine months ended September 30, 2016, the Company granted restricted stock awards in accordance with the 2014 Plan totaling 91,483 shares. The restricted stock awards vest over a range of a 1 - 3 year period. The fair value of restricted stock awards is determined based on the closing stock price of Company common shares on the grant date. The weighted-average grant date fair value of the restricted stock awards granted was $19.61 per share. As of September 30, 2016, the total unrecognized compensation cost related to non-vested awards totaled $1.9 million, and is expected to be recognized over a weighted average period of approximately 1.77 years. Market-based stock awards During the nine months ended September 30, 2016, the Company granted market-based stock awards of 26,594 shares in accordance with the 2014 Plan. These shares have a five-year performance period. The restricted stock shares vest upon the later of the Company’s stock price achieving an established price goal during the performance period, and the third anniversary of the date of grant. The fair value of these awards was determined using a Monte Carlo Simulation at grant date. The grant date fair value of these awards was $11.28. As of September 30, 2016, the total unrecognized compensation cost related to non-vested awards totaled $0.3 million, and is expected to be recognized over a weighted average period of approximately 2.2 years. Performance stock units During the nine months ended September 30, 2016, the Company granted 91,342 performance stock units in accordance with the 2014 Plan. These performance stock units granted represent initial target awards and do not reflect potential increases or decreases resulting from the final performance results, which are to be determined at the end of the three-year performance period. The actual number of shares to be awarded at the end of the performance period will range from 0% - 150% of the initial target awards. 60% of the award is based on the Company’s cumulative earnings per share (EPS target) during the performance period, and 40% of the award is based on the Company’s cumulative total shareholder return (TSR target), or TSR, during the performance period. The Company’s TSR will be compared to the respective TSRs of the companies comprising the KBW Regional Index to determine the shares awarded. The fair value of the EPS target portion of the award was determined based on the closing stock price of the Company’s common stock on the grant date. The fair value of the TSR target portion of the award was determined using a Monte Carlo Simulation at the grant date. The weighted-average grant date fair value per unit of the EPS target portion and the TSR target portion was $19.56 and $16.52, respectively. As of September 30, 2016, the total unrecognized compensation cost related to non-vested units totaled $1.1 million, and is expected to be recognized over a weighted average period of approximately 2.4 years. The following table summarizes restricted stock and performance stock unit activity for the nine months ended September 30, 2016: Weighted Weighted Restricted Average Grant- Performance Average Grant- Shares Date Fair Value Stock Units Date Fair Value Unvested at December 31, 2015 $ — $ — Vested — — Granted Forfeited Surrendered — — Unvested at September 30, 2016 $ $ Expense related to non-vested restricted awards and units totaled $0.7 million and $0.8 million during the three months ended September 30, 2016 and 2015, respectively, and $2.2 million and $2.0 million during the nine months ended September 30, 2016 and 2015, respectively, and is included in salaries and benefits in the consolidated statements of operations. Employee Stock Purchase Plan The 2014 Employee Stock Purchase Plan (“ESPP”) is intended to be a qualified plan within the meaning of Section 423 of the Internal Revenue Code of 1986 and allows eligible employees to purchase shares of common stock through payroll deductions up to a limit of $25,000 per calendar year and 2,000 shares per offering period. The price an employee pays for shares is 90.0% of the fair market value of Company common stock on the last day of the offering period. The offering period is the six-month period commencing on March 1 and September 1 of each year and ending on August 31 and February 28 (or February 29 in the case of a leap year) of each year. There is no vesting or other restrictions on the stock purchased by employees under the ESPP. Under the ESPP, the total number of shares of common stock reserved for issuance totaled 400,000 shares. Under the ESPP, employees purchased 19,209 shares during the nine months ended September 30, 2016. There were 366,337 shares available for issuance under the ESPP at September 30, 2016.

Warrants	Note 10 Warrants The Company had 725,750 outstanding warrants to purchase Company stock as of September 30, 2016 and December 31, 2015, respectively. The warrants were granted to certain lead shareholders of the Company at the time of the Company’s initial capital raise (2009-2010), all with an exercise price of $20.00 per share. During December 2015, the Company modified its remaining warrant agreements resulting in the reclassification of $3.1 million to additional paid-in capital included in the consolidated statements of financial condition as of September 30, 2016. The modified term of the warrants is for ten years and six months from the date of grant and the expiration dates of the warrants range from April 20, 2020 - September 23, 2020. Prior to the warrants reclassification to additional paid-in-capital during the fourth quarter of 2015, the warrants were revalued each reporting period. The Company recorded a benefit of $0.5 million and $0.4 million for the three and nine months ended September 30, 2015, respectively, in the consolidated statements of operations, resulting from the change in fair value of the warrant liability.

Earnings Per Share [Abstract]
Income Per Share	Note 12 Income Per Share The Company calculates income per share under the two-class method, as certain non-vested share awards contain non-forfeitable rights to dividends. As such, these awards are considered securities that participate in the earnings of the Company. Non-vested shares are discussed further in note 9. The Company had 26,282,224 and 30,318,684 shares outstanding (inclusive of Class A and B) as of September 30, 2016 and 2015, respectively, exclusive of issued non-vested restricted shares. Certain stock options and non-vested restricted shares are potentially dilutive securities, but are not included in the calculation of diluted earnings per share because to do so would have been anti-dilutive for the three and nine months ended September 30, 2016 and 2015. The following table illustrates the computation of basic and diluted income per share for the three and nine months ended September 30, 2016 and 2015: For the three months ended For the nine months ended September 30, 2016 September 30, 2015 September 30, 2016 September 30, 2015 Net income $ $ $ $ Less: income allocated to participating securities Income allocated to common shareholders $ $ $ $ Weighted average shares outstanding for basic income per common share Dilutive effect of equity awards Dilutive effect of warrants — Weighted average shares outstanding for diluted income per common share Basic income per share $ $ $ $ Diluted income per share $ $ $ $ The Company had 2,669,859 and 3,060,664 outstanding stock options to purchase common stock at weighted average exercise prices of $19.82 and $19.86 per share at September 30, 2016 and 2015, respectively, which have time-vesting criteria, and as such, any dilution is derived only for the time frame in which the vesting criteria had been met and where the inclusion of those stock options is dilutive. Additionally, the Company had outstanding warrants to purchase shares of the Company’s common stock totaling 725,750 as of September 30, 2016 and 2015, respectively. The warrants have an exercise price of $20.00, which were in-the-money for purposes of dilution calculations during the three and nine months ended September 30, 2016, and three months ended September 30, 2015, and out-of-the-money during the nine months ended September 30, 2015. The Company had 912,783 and 1,046,980 unvested restricted shares and units issued as of September 30, 2016 and 2015, respectively, which have performance, market and/or time-vesting criteria, and as such, any dilution is derived only for the time frame in which the vesting criteria had been met and where the inclusion of those restricted shares and units is dilutive.

Income Tax Disclosure [Abstract]
Income Taxes	Note 13 Income Taxes The income tax rate for the three and nine months ended September 30, 2016 was an expense of 16.9% and 18.0%, respectively, compared to a benefit for both periods in 2015. The three and nine months ended September 30, 2016 rate was calculated based on a full year forecast method. The quarterly tax rate differs from the federal statutory rate primarily due to interest income from tax-exempt lending, bank-owned life insurance income, and the relationship of these items to pre-tax income. The tax rate for the three and nine months ended September 30, 2016 is not comparable to the three and nine months ended September 30, 2015 as the Company moved from recording income tax expense on a discrete quarter basis in 2015 to a full year forecast method in 2016. The tax benefit recorded for the three and nine months ended September 30, 2015 was due to income from tax-exempt lending and tax-exempt bank-owned life insurance in excess of pre-tax income for the periods then ended. See management’s discussion and analysis for further information.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Note 14 Derivatives Risk management objective of using derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company has established policies that neither carrying value nor fair value at risk should exceed established guidelines. The Company has designed strategies to confine these risks within the established limits and identify appropriate trade-offs in the financial structure of its balance sheet. These strategies include the use of derivative financial instruments to help achieve the desired balance sheet repricing structure while meeting the desired objectives of its clients. Currently, the Company employs certain interest rate swaps that are designated as fair value hedges as well as economic hedges. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions. Fair values of derivative instrument of the balance sheet The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the consolidated statements of financial condition as of September 30, 2016 and December 31, 2015. Information about the valuation methods used to measure fair value is provided in note 16 of the consolidated financial statements. Asset Derivatives Fair Value Liability Derivatives Fair Value Balance Sheet September 30, December 31, Balance Sheet September 30, December 31, Location 2016 2015 Location 2016 2015 Derivatives designated as hedging instruments: Interest rate products Other assets $ $ Other liabilities $ $ Total derivatives designated as hedging instruments $ $ $ $ Derivatives not designated as hedging instruments: Interest rate products Other assets $ $ Other liabilities $ $ Interest rate lock commitments Other assets — Other liabilities — — Forward contracts Other assets — — Other liabilities — Forward loan sales agreements Loans held for sale — Loans held for sale — — Total derivatives not designated as hedging instruments $ $ $ $ Fair value hedges Interest rate swaps designated as fair value hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. As of September 30, 2016, the Company had 45 interest rate swaps with a notional amount of $374.9 million that were designated as fair value hedges of interest rate risk associated with the Company’s fixed-rate loans. The Company had 31 outstanding interest rate swaps with a notional amount of $273.3 million that were designated as fair value hedges of interest rate risk associated with Company’s fixed-rate loans as of December 31, 2015. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in earnings. The Company includes the gain or loss on the hedged items in the same line item as the offsetting loss or gain on the related derivatives. During the three and nine months ended September 30, 2016, the Company recognized a net loss of $48 thousand and $1.2 million, respectively, in non-interest income related to hedge ineffectiveness. During the three and nine months ended September 30 2015, the Company recognized a net loss of $522 thousand and $255 thousand, respectively, in non-interest income related to hedge ineffectiveness. Non-designated hedges Derivatives not designated as hedges are not speculative and consist of interest rate swaps with commercial banking clients that facilitate their respective risk management strategies. Interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the client swaps and the offsetting swaps are recognized directly in earnings. As of September 30, 2016, the Company had 37 matched interest rate swap transactions with an aggregate notional amount of $139.2 million related to this program. As of December 31, 2015, the Company had 20 matched interest rate swap transactions with an aggregate notional amount of $68.1 million related to this program. As part of its mortgage banking activities, the Company enters into interest rate lock commitments, which are commitments to originate loans where the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The Company then locks in the loan and interest rate with an investor and commits to deliver the loan if settlement occurs ("best efforts") or commits to deliver the locked loan in a binding ("mandatory") delivery program with an investor. Fair value changes of certain loans under interest rate lock commitments are hedged with forward sales contracts of mortgage backed securities ("MBS"). Forward sales contracts of MBS are recorded at fair value with changes in fair value recorded in non-interest income. Interest rate lock commitments and commitments to deliver loans to investors are considered derivatives. The market value of interest rate lock commitments and best efforts contracts are not readily ascertainable with precision because they are not actively traded in stand-alone markets. The Company determines the fair value of interest rate lock commitments and delivery contracts by measuring the fair value of the underlying asset, which is impacted by current interest rates, taking into consideration the probability that the interest rate lock commitments will close or will be funded. Certain additional risks arise from these forward delivery contracts in that the counterparties to the contracts may not be able to meet the terms of the contracts. The Company does not expect any counterparty to any MBS contract to fail to meet its obligation. Additional risks inherent in mandatory delivery programs include the risk that, if the Company fails to deliver the loans subject to interest rate risk lock commitments, it will still be obligated to “pair off” MBS to the counterparty under the forward sales agreement. Should this be required, the Company could incur significant costs in acquiring replacement loans and such costs could have an adverse effect on the consolidated financial statements. The fair value of the mortgage banking derivative is recorded as a freestanding asset or liability with the change in value being recognized in current earnings during the period of change. The Company had 152 interest rate lock commitments with a notional value of $26.3 million and 22 forward contracts with a notional value of $25.8 million at September 30, 2016. The Company had six forward loan sales commitments with a notional value of $1.1 million at September 30, 2016. At December 31, 2015, the Company had no mandatory delivery interest rate lock commitments, forward sale contracts or forward loan sales commitments, and the best efforts mortgage banking derivatives were immaterial to the consolidated financial statements. Effect of derivative instruments on the consolidated statements of operations The tables below present the effect of the Company’s derivative financial instruments on the consolidated statements of operations for the three and nine months ended September 30, 2016 and 2015: Location of gain (loss) Amount of gain (loss) recognized in income on derivatives Derivatives in fair value recognized in income on For the three months ended September 30, For the nine months ended September 30, hedging relationships derivatives 2016 2015 2016 2015 Interest rate products Other non-interest income $ $ $ $ Total $ $ $ $ Location of gain (loss) Amount of gain (loss) recognized in income on hedged items recognized in income on For the three months ended September 30, For the nine months ended September 30, Hedged items hedged items 2016 2015 2016 2015 Interest rate products Other non-interest income $ $ $ $ Total $ $ $ $ Location of gain (loss) Amount of gain (loss) recognized in income on derivatives Derivatives not designated recognized in income on For the three months ended September 30, For the nine months ended September 30, as hedging instruments derivatives 2016 2015 2016 2015 Interest rate products Other non-interest income $ $ $ $ Interest rate lock commitments Other non-interest income — — Forward contracts Other non-interest income — — Forward loan sales agreements Other non-interest income — — Total $ $ $ $ Credit-risk-related contingent features The Company has agreements with its derivative counterparties that contain a provision where if the Company defaults on any of its indebtedness for reasons other than an error or omission of an administrative or operational nature, 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 also has agreements with certain of its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well/adequately capitalized institution, then the counterparty has the right to terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of September 30, 2016 and December 31, 2015, the termination value of derivatives in a net liability position related to these agreements was $28.9 million and $9.0 million, respectively, which includes accrued interest but excludes any adjustment for nonperformance risk. The Company has minimum collateral posting thresholds with certain of its derivative counterparties and as of September 30, 2016 and December 31, 2015, the Company had posted $31.6 million and $8.2 million, respectively, in eligible collateral. If the Company had breached any of these provisions at September 30, 2016, it could have been required to settle its obligations under the agreements at the termination value.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 15 Commitments and Contingencies In the normal course of business, the Company enters into various off-balance sheet commitments to help meet the financing needs of clients. These financial instruments include commitments to extend credit, commercial and consumer lines of credit and standby letters of credit. The same credit policies are applied to these commitments as the loans on the consolidated statements of financial condition; however, these commitments involve varying degrees of credit risk in excess of the amount recognized in the consolidated statements of financial condition. At September 30, 2016 and December 31, 2015, the Company had loan commitments totaling $557.0 million and $627.2 million, respectively, and standby letters of credit that totaled $12.6 million and $9.8 million, respectively. The total amounts of unused commitments do not necessarily represent future credit exposure or cash requirements, as commitments often expire without being drawn upon. However, the contractual amount of these commitments, offset by any additional collateral pledged, represents the Company’s potential credit loss exposure. Total unfunded commitments at September 30, 2016 and December 31, 2015 were as follows: September 30, 2016 December 31, 2015 Commitments to fund loans $ $ Credit card lines of credit — Unfunded commitments under lines of credit Commercial and standby letters of credit Total $ $ Commitments to fund loans —Commitments to fund loans are legally binding agreements to lend to clients in accordance with predetermined contractual provisions providing there have been no violations of any conditions specified in the contract. These commitments are generally at variable interest rates and are for specific periods or contain termination clauses and may require the payment of a fee. The total amounts of unused commitments are not necessarily representative of future credit exposure or cash requirements, as commitments often expire without being drawn upon. Credit card lines of credit —The Company extends lines of credit to clients through the use of credit cards issued by the Bank. These lines of credit represent the maximum amounts allowed to be funded, many of which will not exhaust the established limits, and as such, these amounts are not necessarily representations of future cash requirements or credit exposure. During the first quarter of 2016, the Company sold its credit card lines of credit and entered into a joint marketing agreement with an unrelated third-party. As a result of this action, the Company will be able to better provide small business and consumers with access to a more competitive suite of products and services. Unfunded commitments under lines of credit —In the ordinary course of business, the Company extends revolving credit to its clients. These arrangements may require the payment of a fee. Commercial and standby letters of credit —As a provider of financial services, the Company routinely issues commercial and standby letters of credit, which may be financial standby letters of credit or performance standby letters of credit. These are various forms of “back-up” commitments to guarantee the performance of a client to a third party. While these arrangements represent a potential cash outlay for the Company, the majority of these letters of credit will expire without being drawn upon. Letters of credit are subject to the same underwriting and credit approval process as traditional loans, and as such, many of them have various forms of collateral securing the commitment, which may include real estate, personal property, receivables or marketable securities. Contingencies In the ordinary course of business, the Company and the Bank may be subject to litigation. Based upon the available information and advice from the Company’s legal counsel, management does not believe that any potential, threatened or pending litigation to which it is a party will have a material adverse effect on the Company’s liquidity, financial condition or results of operations.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 16 Fair Value Measurements The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to disclose the fair value of its financial instruments. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. For disclosure purposes, the Company groups its financial and non-financial assets and liabilities into three different levels based on the nature of the instrument and the availability and reliability of the information that is used to determine fair value. The three levels are defined as follows: · Level 1—Includes assets or liabilities in which the inputs to the valuation methodologies are based on unadjusted quoted prices in active markets for identical assets or liabilities. · Level 2—Includes assets or liabilities in which the inputs to the valuation methodologies are based on similar assets or liabilities in inactive markets, quoted prices for identical or similar assets or liabilities in inactive markets, and inputs other than quoted prices that are observable, such as interest rates, yield curves, volatilities, prepayment speeds, and other inputs obtained from observable market input. · Level 3—Includes assets or liabilities in which the inputs to the valuation methodology are based on at least one significant assumption that is not observable in the marketplace. These valuations may rely on management’s judgment and may include internally-developed model-based valuation techniques. Level 1 inputs are considered to be the most transparent and reliable and level 3 inputs are considered to be the least transparent and reliable. The Company assumes the use of the principal market to conduct a transaction of each particular asset or liability being measured and then considers the assumptions that market participants would use when pricing the asset or liability. Whenever possible, the Company first looks for quoted prices for identical assets or liabilities in active markets (level 1 inputs) to value each asset or liability. However, when inputs from identical assets or liabilities on active markets are not available, the Company utilizes market observable data for similar assets and liabilities. The Company maximizes the use of observable inputs and limits the use of unobservable inputs to occasions when observable inputs are not available. The need to use unobservable inputs generally results from the lack of market liquidity of the actual financial instrument or of the underlying collateral. Although, in some instances, third party price indications may be available, limited trading activity can challenge the observability of these quotations. Changes in the valuation inputs used for measuring the fair value of financial instruments may occur due to changes in current market conditions or other factors. Such changes may necessitate a transfer of the financial instruments to another level in the hierarchy based on the new inputs used. The Company recognizes these transfers at the end of the reporting period that the transfer occurs. During the nine months ended September 30, 2016 and 2015, there were no transfers of financial instruments between the hierarchy levels. The following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of each instrument under the valuation hierarchy: Fair Value of Financial Instruments Measured on a Recurring Basis Investment securities available-for-sale —Investment securities available-for-sale are carried at fair value on a recurring basis. To the extent possible, observable quoted prices in an active market are used to determine fair value and, as such, these securities are classified as level 1. At September 30, 2016 and December 31, 2015, the Company did not hold any level 1 securities. When quoted market prices in active markets for identical assets or liabilities are not available, quoted prices of securities with similar characteristics, discounted cash flows or other pricing characteristics are used to estimate fair values and the securities are then classified as level 2. Interest rate swap derivatives —The Company's derivative instruments are limited to interest rate swaps that may be accounted for as fair value hedges or non-designated hedges. The fair values of the swaps incorporate credit valuation adjustments in order to appropriately reflect nonperformance risk in the fair value measurements. The credit valuation adjustment is the dollar amount of the fair value adjustment related to credit risk and utilizes a probability weighted calculation to quantify the potential loss over the life of the trade. The credit valuation adjustments are calculated by determining the total expected exposure of the derivatives (which incorporates both the current and potential future exposure) and then applying the respective counterparties’ credit spreads to the exposure offset by marketable collateral posted, if any. Certain derivative transactions are executed with counterparties who are large financial institutions ("dealers"). International Swaps and Derivative Association Master Agreements ("ISDA") and Credit Support Annexes ("CSA") are employed for all contracts with dealers. These contracts contain bilateral collateral arrangements. The fair value inputs of these financial instruments are determined using discounted cash flow analysis through the use of third-party models whose significant inputs are readily observable market parameters, primarily yield curves, with appropriate adjustments for liquidity and credit risk, and are classified as level 2. Mortgage banking derivatives —The Company relies on a third-party pricing service to value its mortgage banking derivative financial assets and liabilities, which the Company classifies as a level 3 valuation. The external valuation model to estimate the fair value of its interest rate lock commitments to originate residential mortgage loans held for sale includes grouping the interest rate lock commitments by interest rate and terms, applying an estimated pull-through rate based on historical experience, and then multiplying by quoted investor prices determined to be reasonably applicable to the loan commitment groups based on interest rate, terms, and rate lock expiration dates of the loan commitment groups. The Company also relies on an external valuation model to estimate the fair value of its forward commitments to sell residential mortgage loans (i.e., an estimate of what the Company would receive or pay to terminate the forward delivery contract based on market prices for similar financial instruments), which includes matching specific terms and maturities of the forward commitments against applicable investor pricing. The tables below present the financial instruments measured at fair value on a recurring basis as of September 30, 2016 and December 31, 2015 on the consolidated statements of financial condition utilizing the hierarchy structure described above: September 30, 2016 Level 1 Level 2 Level 3 Total Assets: Investment securities available-for-sale: Mortgage-backed securities (“MBS”): Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises $ — $ $ — $ Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises — — Municipal securities — Other securities — — Interest rate swap derivatives — — Mortgage banking derivatives — — Total assets at fair value $ — $ $ $ Liabilities: Interest rate swap derivatives $ — $ $ — $ Mortgage banking derivatives — — Total liabilities at fair value $ — $ $ $ December 31, 2015 Level 1 Level 2 Level 3 Total Assets: Investment securities available-for-sale: Mortgage-backed securities (“MBS”): Residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises $ — $ $ — $ Other residential MBS issued or guaranteed by U.S. Government agencies or sponsored enterprises — — Municipal securities — — Other securities — — Interest rate swap derivatives — — Total assets at fair value $ — $ $ $ Liabilities: Interest rate swap derivatives $ — $ $ — $ Total liabilities at fair value $ — $ $ — $ The table below details the changes in level 3 financial instruments during the nine months ended September 30, 2016 and September 30, 2015: Other Municipal Mortgage banking securities securities derivatives, net Balance at December 31, 2014 $ $ — $ — Change in value — — Purchase through acquisition — — Net change in Level 3 — Balance at September 30, 2015 $ $ $ — Balance at December 31, 2015 $ $ $ — Gain included in earnings, net — — Net change in Level 3 — — Balance at September 30, 2016 $ $ $ Fair Value Measured on a Non-recurring Basis Certain assets may be recorded at fair value on a non-recurring basis as conditions warrant. These non-recurring fair value measurements typically result from the application of lower of cost or fair value accounting or a write-down occurring during the period. The Company records collateral dependent loans that are considered to be impaired at their estimated fair value. A loan is considered impaired when it is probable that the Company will be unable to collect all contractual amounts due in accordance with the terms of the loan agreement. Collateral dependent impaired loans are measured based on the fair value of the collateral. The Company relies on third-party appraisals and internal assessments in determining the estimated fair values of these loans. The inputs used to determine the fair values of loans are considered level 3 inputs in the fair value hierarchy. At September 30, 2016, the Company measured one loan not accounted for under ASC 310-30 at fair value on a non-recurring basis, with a carrying balance of $6.4 million and specific reserve balance of $1.5 million. At September 30, 2015, the Company measured seven loans with a total carrying balance of $16.1 million and total specific reserves of $3.2 million. The Company may be required to record fair value adjustments on loans held-for-sale on a non-recurring basis. The non-recurring fair value adjustments could involve lower of cost or fair value accounting and may include write-downs. OREO is recorded at the lower of the cost basis or the fair value of the collateral less estimated selling costs. The estimated fair values of OREO are updated periodically and further write-downs may be taken to reflect a new basis. The Company recognized $0.3 million and $0.8 million of OREO impairments in its consolidated statements of operations during the nine months ended September 30, 2016 and 2015, respectively. The fair values of OREO are derived from third party price opinions or appraisals that generally use an income approach or a market value approach. If reasonable comparable appraisals are not available, then the Company may use internally developed models to determine fair values. The inputs used to determine the fair values of OREO are considered level 3 inputs in the fair value hierarchy. Premise and equipment held-for-sale are written down to estimated fair value less costs to sell in the period in which the held-for-sale criterial are met. Fair value is estimated in a process which considers current local commercial real estate market conditions and the judgment of the sales agents and often involves obtaining third party appraisals from certified real estate appraisers. These fair value measurements are classified as level 3. Unobservable inputs to these measures, which include estimates and judgments often used in conjunction with appraisals, are not readily quantifiable. The Company recognized $1.1 million of impairments in its unaudited consolidated statements of operations related to banking centers classified as held-for-sale during the nine months ended September 30, 2015. The table below provides information regarding the assets recorded at fair value on a non-recurring basis during the nine months ended September 30, 2016 and 2015: September 30, 2016 Total Losses from fair value changes Other real estate owned $ $ Impaired loans September 30, 2015 Total Losses from fair value changes Other real estate owned $ $ Impaired loans Premise and Equipment The Company did not record any liabilities for which the fair value was made on a non-recurring basis during the nine months ended September 30, 2016. The following table provides information about the valuation techniques and unobservable inputs used in the valuation of financial instruments falling within level 3 of the fair value hierarchy as of September 30, 2016. The table below excludes non-recurring fair value measurements of collateral value used for impairment measures for OREO and premise and equipment. These valuations utilize third party appraisal or broker price opinions, and are classified as level 3 due to the significant judgment involved: Fair value at September 30, 2016 Valuation Technique Unobservable Input Qualitative Measures Other available-for-sale securities $ Par value Par value Municipal securities Par value Par value Impaired loans Appraised value Appraised values Discount rate 0% - 25%

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 17 Fair Value of Financial Instruments The fair value of a financial instrument is the amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is determined based upon quoted market prices to the extent possible; 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 that may be significantly impacted by the assumptions used, including the discount rate and estimates of future cash flows. Changes in any of these assumptions could significantly affect the fair value estimates. The fair value of the financial instruments listed below does not reflect a premium or discount that could result from offering all of the Company’s holdings of financial instruments at one time, nor does it reflect the underlying value of the Company, as ASC Topic 825 excludes certain financial instruments and all non-financial instruments from its disclosure requirements. The fair value of financial instruments at September 30, 2016 and December 31, 2015, including methods and assumptions utilized for determining fair value of financial instruments, are set forth below: Level in fair value September 30, 2016 December 31, 2015 measurement Carrying Estimated Carrying Estimated hierarchy amount fair value amount fair value ASSETS Cash and cash equivalents Level 1 $ $ $ $ Mortgage-backed securities—residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises available-for-sale Level 2 Mortgage-backed securities—other residential mortgage-backed securities issued or guaranteed by U.S. Government agencies or sponsored enterprises available-for-sale Level 2 Municipal securities Level 2 — — Municipal securities Level 3 Other available-for-sale securities Level 3 Mortgage-backed securities—residential mortgage pass-through securities issued or guaranteed by U.S. Government agencies or sponsored enterprises held-to-maturity Level 2 Mortgage-backed securities—other residential mortgage-backed securities issued or guaranteed by U.S. Government agencies or sponsored enterprises held-to-maturity Level 2 Non-marketable securities Level 2 Loans receivable, net Level 3 Loans held-for-sale Level 2 Accrued interest receivable Level 2 Interest rate swap derivatives Level 2 Mortgage banking derivatives Level 3 — — LIABILITIES Deposit transaction accounts Level 2 Time deposits Level 2 Securities sold under agreements to repurchase Level 2 Federal Home Loan Bank advances Level 2 Accrued interest payable Level 2 Interest rate swap derivatives Level 2 Mortgage banking derivatives Level 3 — — Cash and cash equivalents Cash and cash equivalents have a short-term nature and the estimated fair value is equal to the carrying value. S ecurities purchased under agreements to resell The fair value of securities purchased under agreements to resell is estimated by discounting contractual maturities utilizing current market rates for similar instruments. Investment securities The estimated fair value of investment securities is based on quoted market prices or bid quotations received from securities dealers. Other investment securities, including securities that are held for regulatory purposes are carried at cost, less any other- than-temporary impairment. Loans receivable The estimated fair value of the loan portfolio is estimated using a discounted cash flow analysis using a discount rate based on interest rates offered at the respective measurement dates for loans with similar terms to borrowers of similar credit quality. The allowance for loan losses is considered a reasonable estimate of any required adjustment to fair value to reflect the impact of credit risk. The estimates of fair value do not incorporate the exit-price concept prescribed by ASC Topic 820, Fair Value Measurements and Disclosures . Loans held-for-sale Loans held-for-sale are carried at the lower of aggregate cost or estimated fair value. The portfolio consists primarily of fixed rate residential mortgage loans that are sold within 45 days. The estimated fair value is based on quoted market prices for similar loans in the secondary market and is classified as level 2. Accrued interest receivable Accrued interest receivable has a short-term nature and the estimated fair value is equal to the carrying value. Deposits The estimated fair value of deposits with no stated maturity, such as non-interest bearing demand deposits, savings, NOW accounts, and money market accounts, is equal to the amount payable on demand. The fair value of interest-bearing time deposits is based on the discounted value of contractual cash flows of such deposits, taking into account the option for early withdrawal. The discount rate is estimated using the current market rates offered by the Company, at the respective measurement dates, for deposits of similar remaining maturities. Derivative assets and liabilities Fair values for derivative assets and liabilities are fully described in note 16 of the consolidated financial statements. Securities sold under agreements to repurchase The vast majority of the Company’s repurchase agreements are overnight transactions that mature the day after the transaction, and as a result of this short-term nature, the estimated fair value is equal to the carrying value. Accrued interest payable Accrued interest payable has a short-term nature and the estimated fair value is equal to the carrying value.

Accounting Policies [Abstract]
Loans held for sale	Loans held for sale— The Company enters into commitments to originate residential mortgage loans whereby the interest rate on the loan is determined prior to funding (i.e. interest rate lock commitments). Such interest rate lock commitments on mortgage loans to be sold in the secondary market are considered to be derivatives. To protect against the price risk inherent in residential mortgage loan commitments, the Company utilizes both "best efforts" and "mandatory delivery" forward loan sale commitments to mitigate the risk of potential increases or decreases in the values of loans that would result from the change in market rates for such loans. Under a "best efforts" contract, the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor and the investor commits to a price that it will purchase the loan from the Company only if the loan to the underlying borrower closes. As a result, the Company is not generally exposed to gains or losses on loans sold utilizing best efforts due to changes in underlying market interest rates between the time of the rate lock and loan sale. The market value of interest rate lock commitments and best efforts contracts are not readily ascertainable with precision because rate lock commitments and best efforts contracts are not actively traded. However, because of the high correlation between rate lock commitments and best efforts contracts offsetting market value changes, no gain or loss should occur on the interest rate lock commitments. Under a "mandatory delivery" contract, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. This typically happens after the loan to the underlying borrower closes. The Company manages the interest rate risk on interest rate lock commitments by entering into forward sale contracts of mortgage backed securities, whereby the Company obtains the right to deliver securities to investors in the future at a specified price. Such contracts are accounted for as derivatives and are recorded at fair value as derivative assets or liabilities. They are carried on the consolidated statements of financial condition within other assets or other liabilities and changes in fair value are recorded in other non-interest income within the consolidated statements of operations. The period of time between issuance of a loan commitment to the customer and closing of the loan to an investor generally ranges from 30 - 90 days under normal market conditions. The gross gains on loan sales are recognized based on new loan commitments with adjustment for price and pair-off activity. Commission expenses on loans held for sale are recognized based on loans closed. Income taxes
Income taxes	Income taxes — For the three and nine months ended September 30, 2016, the Company utilized the full year forecast method to calculated its interim income tax provision. For the three and nine months ended September 30, 2015, the Company utilized the discrete effective tax rate method, as allowed by Accounting Standards codification (“ASC”) 740-270-30-18, “Income Taxes-Interim Reporting,” to calculate its interim income tax provision. The discrete method is applied when the application of the estimated annual effective tax rate is impractical because it is not possible to reliably estimate the annual effective tax rate. The discrete method treats the year-to-date period as if it was the annual period and determines the income tax expense or benefit on that basis. The Company believed that, at that time, the use of this discrete method was more appropriate than the annual effective tax rate method as the estimated annual effective tax rate method was not reliable due to (1) the levels of tax-exempt income in relation to pre-tax income, (2) the impact of the warrant liability which is non-taxable and (3) the impact and variability of FDIC Indemnification amortization on pre-tax income. See further discussion in note 13.
Recent Accounting Pronouncements	Revenue from Contracts with Customers —In May 2014, the FASB issued ASU 2014-09, " Revenue from Contracts with Customers ." This update supersedes revenue recognition requirements in ASC Topic 605, Revenue Recognition , including most industry-specific revenue recognition guidance in the FASB Accounting Standards Codification. The new guidance stipulates that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides specific steps that entities should apply in order to achieve this principle. The amendments are effective for interim and annual periods beginning after December 15, 2017, with early application permitted for interim and annual periods beginning after December 15, 2016. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. The Company is in the process of evaluating the impact of the ASU's adoption on the Company's consolidated financial statements. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities —In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825). ASU No. 2016-01 revises the classification and measurement of investments in certain equity investments and the presentation of certain fair value changes for certain financial liabilities measured at fair value. ASU No. 2016-01 requires the change in fair value of many equity investments to be recognized in net income. ASU No. 2016-01 is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. Adopting ASU No. 2016-01 may result in a cumulative effect adjustment to the consolidated statements of changes in shareholders’ equity as of the beginning of the year of adoption. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. Leases —In February 2016, the FASB issued ASU 2016-02, Leases. The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC Topic 840, Leases . The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statements. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption of the amendments in the update is permitted. The Company is in the process of evaluating the impact of the ASU's adoption on the Company's consolidated financial statements . Improvements to Employee Share-Based Payment Accounting —In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which amends ASC Topic 718, Compensation – Stock Compensation . ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. Financial Instruments - Credit Losses —In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments . This update replaces the current incurred loss methodology for recognizing credit losses with a current expected credit loss model, which requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This amendment broadens the information that an entity must consider in developing its expected credit loss estimates. Additionally, the update amends the accounting for credit losses for available-for-sale debt securities and purchased financial assets with a more-than-insignificant amount of credit deterioration since origination. This update requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of a company’s loan portfolio. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption in fiscal years beginning after December 15, 2018 is permitted. The amendment requires the use of the modified retrospective approach for adoption. The Company is in the process of evaluating the impact of the ASU’s adoption on the Company’s consolidated financial statements. Statement of Cash Flows —In August 2016 , the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payment s. The update amends the guidance in ASC 230, Statement of Cash Flows , and clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows with the objective of reducing the existing diversity in practice related to eight specific cash flow items. The amendments in this update are effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of ASU 2016-15 to have a material impact on its financial statements.
