Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per common share data is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Common shares outstanding include common stock and restricted stock awards where recipients have satisfied the vesting terms. Diluted earnings per common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method for convertible trust preferred securities. The following table presents a summary of per common share data and amounts for the periods indicated. Three months ended September 30, Nine months ended September 30, (in thousands, except per share data) 2015 2014 2015 2014 Net income as reported $ 9,709 $ 8,198 $ 27,771 $ 21,206 Impact of assumed conversions Interest on 9% convertible trust preferred securities, net of income tax — — — 66 Net income available to common shareholders and assumed conversions $ 9,709 $ 8,198 $ 27,771 $ 21,272 Weighted average common shares outstanding 19,995 19,838 19,970 19,729 Incremental shares from assumed conversions of convertible trust preferred securities — — — 76 Additional dilutive common stock equivalents 266 142 266 165 Weighted average diluted common shares outstanding $ 20,261 $ 19,980 $ 20,236 $ 19,970 Basic earnings per common share: $ 0.49 $ 0.41 $ 1.39 $ 1.07 Diluted earnings per common share: $ 0.48 $ 0.41 $ 1.37 $ 1.07 For the three and nine months ended September 30, 2015 and 2014 , the amount of common stock equivalents excluded from the earnings per share calculations because their effect was anti-dilutive was 0.1 million , and 0.3 million common stock equivalents, respectively.

Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include among other considerations (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it is more likely than not the Company would be required to sell the security before its anticipated recovery in market value. At September 30, 2015 , management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired.

This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings: • Grades 1 , 2 , and 3 – Includes loans to borrowers with a continuous record of strong earnings, sound balance sheet condition and capitalization, ample liquidity with solid cash flow, and whose management team has experience and depth within their industry. • Grade 4 – Includes loans to borrowers with positive trends in profitability, satisfactory capitalization and balance sheet condition, and sufficient liquidity and cash flow. • Grade 5 – Includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization, liquidity, and cash flow. • Grade 6 – Includes loans to borrowers where an adverse change or perceived weakness has occurred, but may be correctable in the near future. Alternatively, this rating category may also include circumstances where the borrower is starting to reverse a negative trend or condition, or has recently been upgraded from a 7 , 8 , or 9 rating. • Grade 7 – Watch credits are borrowers that have experienced financial setback of a nature that is not determined to be severe or influence ‘ongoing concern’ expectations. Although possible, no loss is anticipated, due to strong collateral and/or guarantor support. • Grade 8 – Substandard credits will include those borrowers characterized by significant losses and sustained downward trends in balance sheet condition, liquidity, and cash flow. Repayment reliance may have shifted to secondary sources. Collateral exposure may exist and additional reserves may be warranted. • Grade 9 – Doubtful credits include borrowers that may show deteriorating trends that are unlikely to be corrected. Collateral values may appear insufficient for full recovery, therefore requiring a partial charge-off, or debt renegotiation with the borrower. The borrower may have declared bankruptcy or bankruptcy is likely in the near term. All doubtful rated credits will be on non-accrual.

Commitments and Contingencies Disclosure [Abstract]
Commitments	COMMITMENTS AND CONTINGENCIES The Company issues financial instruments with off balance sheet risk in the normal course of the business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company’s extent of involvement and maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. At September 30, 2015 , there were $0.3 million of unadvanced commitments on impaired loans. The contractual amounts of off-balance-sheet financial instruments as of September 30, 2015 , and December 31, 2014 , are as follows: (in thousands) September 30, December 31, Commitments to extend credit $ 1,099,224 $ 947,424 Standby letters of credit 51,701 50,108 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments usually have fixed expiration dates or other termination clauses, may have significant usage restrictions, and may require payment of a fee. Of the total commitments to extend credit at September 30, 2015 , and December 31, 2014 , approximately $101.4 million and $65.9 million , respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon or may be revoked, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate. Other liabilities include approximately $0.2 million for estimated losses attributable to the unadvanced commitments at September 30, 2015 and December 31, 2014 . Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These standby letters of credit are issued to support contractual obligations of the Company’s customers. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. The approximate remaining term of standby letters of credit range from 1 month to 2.4 years at September 30, 2015 . Contingencies The Company and its subsidiaries are, from time to time, parties to various legal proceedings arising out of their businesses. Management believes there are no such proceedings pending or threatened against the Company or its subsidiaries which, if determined adversely, would have a material adverse effect on the business, consolidated financial condition, results of operations or cash flows of the Company or any of its subsidiaries.

Fair Value Measurements	FAIR VALUE MEASUREMENTS Below is a description of certain assets and liabilities measured at fair value. The following table summarizes financial instruments measured at fair value on a recurring basis as of September 30, 2015 and December 31, 2014 , segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: September 30, 2015 (in thousands) Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value Assets Securities available for sale Obligations of U.S. Government-sponsored enterprises $ — $ 100,313 $ — $ 100,313 Obligations of states and political subdivisions — 38,502 3,077 41,579 Residential mortgage-backed securities — 328,604 — 328,604 Total securities available for sale $ — $ 467,419 $ 3,077 $ 470,496 State tax credits held for sale — — 10,089 10,089 Derivative financial instruments — 1,749 — 1,749 Total assets $ — $ 469,168 $ 13,166 $ 482,334 Liabilities Derivative financial instruments $ — $ 1,749 $ — $ 1,749 Total liabilities $ — $ 1,749 $ — $ 1,749 December 31, 2014 (in thousands) Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value Assets Securities available for sale Obligations of U.S. Government-sponsored enterprises $ — $ 91,826 $ — $ 91,826 Obligations of states and political subdivisions — 31,822 3,059 34,881 Residential mortgage-backed securities — 273,439 — 273,439 Total securities available for sale $ — $ 397,087 $ 3,059 $ 400,146 State tax credits held for sale — — 11,689 11,689 Derivative financial instruments — 909 — 909 Total assets $ — $ 397,996 $ 14,748 $ 412,744 Liabilities Derivative financial instruments $ — $ 907 $ — $ 907 Total liabilities $ — $ 907 $ — $ 907 • Securities available for sale . Securities classified as available for sale are reported at fair value utilizing Level 2 and Level 3 inputs. Fair values for Level 2 securities are based upon dealer quotes, market spreads, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions at the security level. At September 30, 2015 , Level 3 securities available for sale consist primarily of three Auction Rate Securities that are valued based on the securities' estimated cash flows, yields of comparable securities, and live trading levels. • State tax credits held for sale. At September 30, 2015 , of the $48.2 million of state tax credits held for sale on the condensed consolidated balance sheet, approximately $10.1 million were carried at fair value. The remaining $38.1 million of state tax credits were accounted for at cost. The Company is not aware of an active market that exists for the 10 -year streams of state tax credit financial instruments. However, the Company’s principal market for these tax credits consists of Missouri state residents who buy these credits and local and regional accounting firms who broker them. As such, the Company employed a discounted cash flow analysis (income approach) to determine the fair value. The fair value measurement is calculated using an internal valuation model with market data including discounted cash flows based upon the terms and conditions of the tax credits. If the underlying project remains in compliance with the various federal and state rules governing the tax credit program, each project will generate about 10 years of tax credits. The inputs to the discounted cash flow calculation include: the amount of tax credits generated each year, the anticipated sale price of the tax credit, the timing of the sale and a discount rate. The discount rate is estimated using the LIBOR swap curve at a point equal to the remaining life in years of credits plus a 205 basis point spread. With the exception of the discount rate, the other inputs to the fair value calculation are observable and readily available. The discount rate is considered a Level 3 input because it is an “unobservable input” and is based on the Company’s assumptions. An increase in the discount rate utilized would generally result in a lower estimated fair value of the tax credits. Alternatively, a decrease in the discount rate utilized would generally result in a higher estimated fair value of the tax credits. Given the significance of this input to the fair value calculation, the state tax credit assets are reported as Level 3 assets. • Derivatives . Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains counterparty quotations to value its interest rate swaps and caps. In addition, the Company validates the counterparty quotations with third party valuation sources. Derivatives with negative fair values are included in Other liabilities in the consolidated balance sheets. Derivatives with positive fair value are included in Other assets in the consolidated balance sheets. Level 3 financial instruments The following table presents the changes in Level 3 financial instruments measured at fair value on a recurring basis as of September 30, 2015 and 2014 . • Purchases, sales, issuances and settlements . There were no Level 3 purchases during the quarter ended September 30, 2015 or 2014 . • Transfers in and/or out of Level 3 . There were no Level 3 transfers during the quarter ended September 30, 2015 and 2014 .

These include assets that are measured at the lower of cost or fair value that were recognized at fair value below cost at the end of the period. The following table presents financial instruments and non-financial assets measured at fair value on a non-recurring basis as of September 30, 2015 .

Impaired loans are reported at the fair value of the underlying collateral for collateral dependent loans. Fair values for impaired loans are obtained from current appraisals by qualified licensed appraisers or independent valuation specialists. Other real estate owned is adjusted to fair value upon foreclosure of the underlying loan. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value less costs to sell. Fair value of other real estate is based upon the current appraised values of the properties as determined by qualified licensed appraisers and the Company’s judgment of other relevant market conditions. Certain state tax credits are reported at cost. Following is a summary of the carrying amounts and fair values of the Company’s financial instruments on the consolidated balance sheets at September 30, 2015 and December 31, 2014 .

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Authoritative Accounting Guidance	NEW AUTHORITATIVE ACCOUNTING GUIDANCE FASB ASU 2014-09, "Revenue from Contracts with Customers" In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers”. The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle of ASU 2014-09 is that an entity recognizes 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. In applying the new guidance, an entity will (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the contract’s performance obligations; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB Accounting Standards Codification. The new guidance was originally effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2016 for public companies. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of this guidance to annual reporting periods beginning after December 15, 2017 for public companies, and permits early adoption on a limited basis. The Company is currently evaluating the new guidance and has not determined the impact this standard may have on its financial statements, nor decided upon the method of adoption. Entities have the option of using either a full retrospective or modified approach to adopt ASU 2014-09. FASB ASU 2014-11, "Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures" In June 2014, the FASB issued ASU No. 2014-11, "Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures." The objective of ASU 2014-11 is to amend the accounting for certain secured financing transactions, and requires enhanced disclosures with respect to transactions recognized as sales in which exposure to the derecognized asset is retained through a separate agreement with the counterparty. In addition, the guidance requires enhanced disclosures with respect to the types and quality of financial assets pledged in secured financing transactions. The guidance became effective in the first quarter of 2015, except for the disclosures regarding the types and quality of financial assets pledged, which became effective in the second quarter of 2015. The adoption of the guidance did not have a material impact on the Company's consolidated balance sheets or statements of operations. FASB ASU 2015-03, "Interest-Imputation of Interest (Subtopic 835-30): FASB Accounting Standards Codification-Simplifying the Presentation of Debt Issuance Costs" In April 2015, the FASB issued ASU No. 2015-03, "Interest-Imputation of Interest (Subtopic 835-30): FASB Accounting Standards Codification-Simplifying the Presentation of Debt Issuance Costs." ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. The objective is to reduce cost and complexity in accounting standards while maintaining the usefulness of information being provided to users of financial statements. The guidance becomes effective in the first quarter of 2016 and requires the Company to apply the new guidance on a retrospective basis upon adoption, but early adoption is permitted for financial statements that have not been previously issued. The Company is currently evaluating the effect of this guidance on its consolidated balance sheets and statements of operations.

Accounting Policies [Abstract]
Business and Consolidation	Basis of Financial Statement Presentation The condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with the accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.
Available-for-sale Securities	Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include among other considerations (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it is more likely than not the Company would be required to sell the security before its anticipated recovery in market value. At September 30, 2015 , management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired.
