Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1: Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission and follow general practices within the banking industry. The results of operations reflect interim adjustments, all of which are of a normal recurring nature and which, in the opinion of Management, are necessary for a fair presentation of the results for the interim periods presented. The interim results for the three months ended March 31, 2016 are not necessarily indicative of the results expected for the full year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes as well as other information included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015.

Significant Accounting Policies [Text Block]	Note 2: Accounting Policies The most significant accounting policies followed by the Company are presented in Note 1 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. These policies, along with the disclosures presented in the other financial statement notes and in this discussion, provide information on how significant assets and liabilities are valued in the financial statements and how those values are determined. Based on the valuation techniques used and the sensitivity of financial statement amounts to the methods, assumptions, and estimates underlying those amounts, Management has identified the allowance for loan losses accounting to be the accounting area requiring the most subjective or complex judgments, and as such could be most subject to revision as new information becomes available. A discussion of the factors affecting accounting for the allowance for loan losses and purchased loans is included in the “Loan Portfolio Credit Risk” discussion below. Certain amounts in prior periods have been reclassified to conform to the current presentation. Application of these principles requires the Company to make certain estimates, assumptions, and judgments that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, the financial statements could reflect different estimates, assumptions, and judgments. Certain accounting policies inherently have a greater reliance on the use of estimates, assumptions and judgments and as such have a greater possibility of producing results that could be materially different than originally reported. Estimates, assumptions and judgments are necessary when assets and liabilities are required to be recorded at fair value, when a decline in the value of an asset not carried on the financial statements at fair value warrants an impairment writedown or valuation reserve to be established, or when an asset or liability needs to be recorded contingent upon a future event. Carrying assets and liabilities at fair value inherently results in more financial statement volatility. The fair values and the information used to record valuation adjustments for certain assets and liabilities are based either on quoted market prices or are provided by other third-party sources, when available. Recently Issued Accounting Standards FASB Accounting Standards Update (ASU) 2016-01 Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, The Company will be required to adopt the ASU provisions on January 1, 2018.

FASB Accounting Standards Update (ASU) 2016-02, Leases (Topic 842), The Company will be required to adopt the ASU provisions January 1, 2019, utilizing the modified retrospective transition approach. Management is evaluating the impact that the ASU will have on the Company’s financial statements. FASB ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, The Company will be required to adopt the ASU provisions January 1, 2017.

The Company evaluates securities on a quarterly basis including changes in security ratings issued by ratings agencies, changes in the financial condition of the issuer, and, for mortgage-backed and asset-backed securities, delinquency and loss information with respect to the underlying collateral, changes in the levels of subordination for the Company’s particular position within the repayment structure and remaining credit enhancement as compared to expected credit losses of the security. Substantially all of these securities continue to be investment grade rated by a major rating agency. In addition to monitoring credit rating agency evaluations, Management performs its own evaluations regarding the credit worthiness of the issuer or the securitized assets underlying asset backed securities. The Company does not intend to sell any investments and has concluded that it is more likely than not that it will not be required to sell the investments prior to recovery of the amortized cost basis. Therefore, the Company does not consider these investments to be other-than-temporarily impaired as of March 31, 2016. The fair values of the investment securities could decline in the future if the general economy deteriorates, inflation increases, credit ratings decline, the issuer’s financial condition deteriorates, or the liquidity for securities declines. As a result, other than temporary impairments may occur in the future.

Given the scale of these borrowers, corporate credit rating agencies do not evaluate the borrowers’ financial condition. The Bank maintains a Loan Review Department which reports directly to the Board of Directors. The Loan Review Department performs independent evaluations of loans and assigns credit risk grades to evaluated loans using grading standards employed by bank regulatory agencies. Loans judged to carry lower-risk attributes are assigned a “pass” grade, with a minimal likelihood of loss. Loans judged to carry higher-risk attributes are referred to as “classified loans,” and are further disaggregated, with increasing expectations for loss recognition, as “substandard,” “doubtful,” and “loss.” Loan Review Department evaluations occur every calendar quarter. If the Bank becomes aware of deterioration in a borrower’s performance or financial condition between Loan Review Department examinations, assigned risk grades are re-evaluated promptly. Credit risk grades assigned by the Loan Review Department are subject to review by the Bank’s regulatory authorities during regulatory examinations.

Fair Value Disclosures [Text Block]	Note 9: Fair Value Measurements The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Available for sale investment securities are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as other real estate owned, impaired loans, certain loans held for investment, investment securities held to maturity, and other assets. These nonrecurring fair value adjustments typically involve the lower-of-cost-or-fair value accounting of individual assets. In accordance with the Fair Value Measurement and Disclosure topic of the Codification, the Company bases its fair values on the price that would be received to sell an asset or paid to transfer a liability in the principal market or most advantageous market for an asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. A fair value measurement reflects all of the assumptions that market participants would use in pricing the asset or liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, and the risk of nonperformance. The Company groups its assets and liabilities measured at fair value into a three-level hierarchy, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. When the valuation assumptions used to measure the fair value of the asset or liability are categorized within different levels of the fair value hierarchy, the asset or liability is categorized in its entirety within the lowest level of the hierarchy. These levels are: Level 1 – Valuation is based upon quoted prices for identical instruments traded in active exchange markets, such as the New York Stock Exchange. Level 1 includes U.S. Treasury and equity securities, which are traded by dealers or brokers in active markets. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 2 includes federal agency securities, mortgage-backed securities, corporate securities, asset-backed securities, and municipal bonds. Level 3 – Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. The Company relies on independent vendor pricing services to measure fair value for investment securities available for sale and investment securities held to maturity. The Company employs three pricing services. To validate the pricing of these vendors, the Company compares vendors’ pricing for each of the securities for consistency; significant pricing differences, if any, are evaluated using all available independent quotes with the quote closely affecting the market generally used as the fair value estimate. In addition, the Company conducts “other than temporary impairment (OTTI)” analysis on a quarterly basis; securities selected for OTTI analysis include all securities at a market price below 95 percent of par value or with a market to book ratio below 95:100. As with any valuation technique used to estimate fair value, changes in underlying assumptions used could significantly affect the results of current and future values. Accordingly, these fair value estimates may not be realized in an actual sale of the securities. The Company regularly reviews the valuation techniques and assumptions used by its vendors and determines which valuation techniques are utilized based on observable market inputs for the type of securities being measured. The Company uses the information to determine the placement in the fair value hierarchy as level 1, 2 or 3. When the Company changes its valuation assumptions for measuring financial assets and financial liabilities at fair value, either due to changes in current market conditions or other factors, or reevaluates the valuation techniques and assumptions used by its vendors, it may need to transfer those assets or liabilities to another level in the hierarchy based on the new information. The Company recognizes these transfers at the end of the reporting period that the transfers occur. For the three months ended March 31, 2016 and 2015, there were no transfers in or out of levels 1, 2 or 3. During the quarter ended June 30, 2015, the Company reevaluated the valuation techniques and assumptions used by its vendors in valuing the Company’s available for sale securities, and based on the evaluation, transferred $437,715 thousand out of level 1 and transferred $437,715 thousand into level 2. There were no transfers into level 1 or into or out of level 3. Subsequent to June 30, 2015 and through the year ended December 31, 2015, there were no transfers into or out of levels 1, 2 or 3.

These adjustments to fair value usually result from application of lower-of-cost or fair-value accounting of individual assets. For assets measured at fair value on a nonrecurring basis that were recorded in the balance sheet at March 31, 2016 and December 31, 2015, the following table provides the level of valuation assumptions used to determine each adjustment and the carrying value of the related assets at period end.

Level 3 includes other real estate owned that has been measured at fair value upon transfer to foreclosed assets and impaired loans collateralized by real property and other business asset collateral where a specific reserve has been established or a chargeoff has been recorded. Losses on other real estate owned represent losses recognized in earnings during the period subsequent to its initial classification as foreclosed assets. The unobservable inputs and qualitative information about the unobservable inputs are not presented due to the unavailability from third party evaluators.

The values assigned do not necessarily represent amounts which ultimately may be realized for assets or paid to settle liabilities. In addition, these values do not give effect to adjustments to fair value which may occur when financial instruments are sold or settled in larger quantities. The carrying amounts in the following table are recorded in the balance sheet under the indicated captions. The Company has not included assets and liabilities that are not financial instruments, such as goodwill, long-term relationships with deposit, merchant processing and trust customers, other purchased intangibles, premises and equipment, deferred taxes and other assets and liabilities.
