Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Basis of Accounting and Consolidation
	The accompanying consolidated financial statements include the accounts of First Mid-Illinois Bancshares, Inc. (“Company”) and its wholly-owned subsidiaries:  Mid-Illinois Data Services, Inc. (“MIDS”), First Mid-Illinois Bank & Trust, N.A. (“First Mid Bank”) and The Checkley Agency, Inc. doing business as First Mid Insurance Group (“First Mid Insurance”).  All significant intercompany balances and transactions have been eliminated in consolidation.   Certain amounts in the prior year’s consolidated financial statements have been reclassified to conform to the 2014 presentation and there was no impact on net income or stockholders’ equity from these reclassifications.  The Company operates as a single segment entity for financial reporting purposes. The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America. Following is a description of the more significant of these policies.
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes.  The Company uses estimates and employs the judgments of management in determining the amount of its allowance for loan losses and income tax accruals and deferrals, in its fair value measurements of investment securities, and in the evaluation of impairment of loans, goodwill, investment securities, and fixed assets. As with any estimate, actual results could differ from these estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses.  In connection with the determination of the allowance for loan losses, management obtains independent appraisals for significant properties.
	Fair Value Measurements
	The fair value of a financial instrument is defined as the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The Company estimates the fair value of a financial instrument using a variety of valuation methods. Where financial instruments are actively traded and have quoted market prices, quoted market prices are used for fair value. When the financial instruments are not actively traded, other observable market inputs, such as quoted prices of securities with similar characteristics, may be used, if available, to determine fair value. When observable market prices do not exist, the Company estimates fair value. The Company’s valuation methods consider factors such as liquidity and concentration concerns. Other factors such as model assumptions, market dislocations, and unexpected correlations can affect estimates of fair value. Imprecision in estimating these factors can impact the amount of revenue or loss recorded.
	At the end of each quarter, the Company assesses the valuation hierarchy for each asset or liability measured. From time to time, assets or liabilities may be transferred within hierarchy levels due to changes in availability of observable market inputs to measure fair value at the measurement date. Transfers into or out of hierarchy levels are based upon the fair value at the beginning of the reporting period. A more detailed description of the fair values measured at each level of the fair value hierarchy can be found in Note 11 – “Disclosures of Fair Values of Financial Instruments.”
	Cash and Cash Equivalents
	For purposes of reporting cash flows, cash equivalents include non-interest bearing and interest bearing cash and due from banks and federal funds sold. Generally, federal funds are sold for one-day periods.
	Certificates of Deposit Investments
	Certificates of deposit investments have original maturities of six to twelve months and are carried at cost.
	Investment Securities
	The Company classifies its investments in debt and equity securities as either held-to-maturity or available-for-sale in accordance with Statement of Financial Accounting  Standards (SFAS) No. 115, “Accounting for Certain Investments in Debt and Equity Securities,” which was codified into ASC 320. Securities classified as held-to-maturity are recorded at cost or amortized cost. Available-for-sale securities are carried at fair value. Fair value calculations are based on quoted market prices when such prices are available. If quoted market prices are not available, estimates of fair value are computed using a variety of techniques, including extrapolation from the quoted prices of similar instruments or recent trades for thinly traded securities, fundamental analysis, or through obtaining purchase quotes. Due to the subjective nature of the valuation process, it is possible that the actual fair values of these investments could differ from the estimated amounts, thereby affecting the financial position, results of operations and cash flows of the Company. If the estimated value of investments is less than the cost or amortized cost, the Company evaluates whether an event or change in circumstances has occurred that may have a significant adverse effect on the fair value of the investment. If such an event or change has occurred and the Company determines that the impairment is other-than-temporary, a further determination is made as to the portion of impairment that is related to credit loss. The impairment of the investment that is related to the credit loss is expensed in the period in which the event or change occurred. The remainder of the impairment is recorded in other comprehensive income.
	Loans
	Loans are stated at the principal amount outstanding net of unearned discounts, unearned income and the allowance for loan losses.  Unearned income includes deferred loan origination fees reduced by loan origination costs and is amortized to interest income over the life of the related loan using methods that approximate the effective interest rate method. Interest on substantially all loans is credited to income based on the principal amount outstanding.
	The Company’s policy is to discontinue the accrual of interest income on any loan that becomes ninety days past due as to principal or interest or earlier when, in the opinion of management there is reasonable doubt as to the timely collection of principal or interest. Nonaccrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collectability of interest or principal.
	Loans expected to be sold are classified as held for sale in the consolidated financial statements and are recorded at the lower of aggregate cost or market value, taking into consideration future commitments to sell the loans.
	Allowance for Loan Losses
	The Company believes the allowance for loan losses is the critical accounting policy that requires the most significant judgments and assumptions used in the preparation of its consolidated financial statements. An estimate of potential losses inherent in the loan portfolio is determined and an allowance for those losses is established by considering factors including historical loss rates, expected cash flows and estimated collateral values. In assessing these factors, the Company use organizational history and experience with credit decisions and related outcomes. The allowance for loan losses represents the best estimate of losses inherent in the existing loan portfolio. The allowance for loan losses is increased by the provision for loan losses charged to expense and reduced by loans charged off, net of recoveries. The Company evaluates the allowance for loan losses quarterly. If the underlying assumptions later prove to be inaccurate based on subsequent loss evaluations, the allowance for loan losses is adjusted.
	The Company estimates the appropriate level of allowance for loan losses by separately evaluating impaired and nonimpaired loans. A specific allowance is assigned to an impaired loan when expected cash flows or collateral do not justify the carrying amount of the loan. The methodology used to assign an allowance to a nonimpaired loan is more subjective. Generally, the allowance assigned to nonimpaired loans is determined by applying historical loss rates to existing loans with similar risk characteristics, adjusted for qualitative factors including the volume and severity of identified classified loans, changes in economic conditions, changes in credit policies or underwriting standards, and changes in the level of credit risk associated with specific industries and markets. Because the economic and business climate in any given industry or market, and its impact on any given borrower, can change rapidly, the risk profile of the loan portfolio is continually assessed and adjusted when appropriate. Notwithstanding these procedures, there still exists the possibility that the assessment could prove to be significantly incorrect and that an immediate adjustment to the allowance for loan losses would be required.
	Premises and Equipment
	Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is charged to expense and determined principally by the straight-line method over the estimated useful lives of the assets. The estimated useful lives for each major depreciable classification of premises and equipment are as follows:
	Buildings and improvements        20 years to 40 years
	Leasehold improvements        5 years to 15 years
	Furniture and equipment        3 years to 7 years
	Goodwill and Intangible Assets
	The Company has goodwill from business combinations, identifiable intangible assets assigned to core deposit relationships and customer lists acquired, and intangible assets arising from the rights to service mortgage loans for others.
	Identifiable intangible assets generally arise from branches acquired that the Company accounted for as purchases.  Such assets consist of the excess of the purchase price over the fair value of net assets acquired, with specific amounts assigned to core deposit relationships and customer lists primarily related to insurance agency.  Intangible assets are amortized by the straight-line method over various periods up to fifteen years.  Management reviews intangible assets for possible impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
	In accordance with the provisions of SFAS No. 142, “Goodwill and Other Intangible Assets,” codified into ASC 350, the Company performed testing of goodwill for impairment as of September 30, 2014 and determined that, as of that date, goodwill was not impaired.  Management also concluded that the remaining amounts and amortization periods were appropriate for all intangible assets.
	Other Real Estate Owned
	Other real estate owned acquired through loan foreclosure is initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. The adjustment at the time of foreclosure is recorded through the allowance for loan losses. Due to the subjective nature of establishing the fair value when the asset is acquired, the actual fair value of the other real estate owned or foreclosed asset could differ from the original estimate. If it is determined that fair value temporarily declines subsequent to foreclosure, a valuation allowance is recorded through noninterest expense. Operating costs associated with the assets after acquisition are also recorded as noninterest expense. Gains and losses on the disposition of other real estate owned and foreclosed assets are netted and posted to other noninterest expense.
	Federal Home Loan Bank Stock
	Federal Home Loan Bank stock is a required investment for institutions that are members of the Federal Home Loan Bank system.  The required investment in the common stock is based on a predetermined formula.
	Income Taxes
	The Company and its subsidiaries file consolidated federal and state income tax returns with each organization computing its taxes on a separate company basis.  Amounts provided for income tax expense are based on income reported for financial statement purposes rather than amounts currently payable under tax laws.
	Deferred tax assets and liabilities are recognized for future tax consequences attributable to the temporary differences existing between the financial statement carrying amounts of assets and liabilities and their respective tax basis, as well as operating loss and tax credit carry forwards.  To the extent that current available evidence about the future raises doubt about the realization of a deferred tax asset, a valuation allowance is established.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized as an increase or decrease in income tax expense in the period in which such change is enacted.
	Additionally, the Company reviews its uncertain tax positions annually under FASB Interpretation No. 48 (FIN No. 48), “Accounting for Uncertainty in Income Taxes,” codified within ASC 740. An uncertain tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount actually recognized is the largest amount of tax benefit that is greater than 50% likely to be recognized on examination. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded. A significant amount of judgment is applied to determine both whether the tax position meets the "more likely than not" test as well as to determine the largest amount of tax benefit that is greater than 50% likely to be recognized. Differences between the position taken by management and that of taxing authorities could result in a reduction of a tax benefit or increase to tax liability, which could adversely affect future income tax expense.
	Trust Department Assets
	Assets held in fiduciary or agency capacities are not included in the consolidated balance sheets since such items are not assets of the Company or its subsidiaries.  Fees from trust activities are recorded on a cash basis over the period in which the service is provided.  Fees are a function of the market value of assets managed and administered, the volume of transactions, and fees for other services rendered, as set forth in the underlying client agreement with the Trust & Wealth Management Division of First Mid Bank.  This revenue recognition involves the use of estimates and assumptions, including components that are calculated based on asset valuations and transaction volumes.  Any out of pocket expenses or services not typically covered by the fee schedule for trust activities are charged directly to the trust account on a gross basis as trust revenue is incurred.
	At December 31, 2014, the Company managed or administered 1,478 accounts with assets totaling approximately $757.3 million. At December 31, 2013, the Company managed or administered 1,498 accounts with assets totaling approximately $722.9 million.
	Convertible Preferred Stock
	Series B Convertible Preferred Stock.  During 2009, the Company sold to certain accredited investors including directors, executive officers, and certain major customers and holders of the Company’s common stock, $24,635,000, in the aggregate, of a newly authorized series of its preferred stock designated as Series B 9% Non-Cumulative Perpetual Convertible Preferred Stock (the “Series B Preferred Stock”). The Series B Preferred Stock had an issue price of $5,000 per share and no par value per share.  The Series B Preferred Stock was issued in a private placement exempt from registration pursuant to Regulation D of the Securities Act of 1933, as amended.
	The Series B Preferred Stock pays non-cumulative dividends semiannually in arrears, when, as and if authorized by the Board of Directors of the Company, at a rate of 9% per year.  Holders of the Series B Preferred Stock will have no voting rights, except with respect to certain fundamental changes in the terms of the Series B Preferred Stock and certain other matters.  In addition, if dividends on the Series B Preferred Stock are not paid in full for four dividend periods, whether consecutive or not, the holders of the Series B Preferred Stock, acting as a class with any other of the Company’s securities having similar voting rights, will have the right to elect two directors to the Company’s Board of Directors.  The terms of office of these directors will end when the Company has paid or set aside for payment full semi-annual dividends for four consecutive dividend periods.
	Each share of the Series B Preferred Stock may be converted at any time at the option of the holder into shares of the Company’s common stock.  The number of shares of common stock into which each share of the Series B Preferred Stock is convertible is the $5,000 liquidation preference per share divided by the Conversion Price initially set at $21.94.  The Conversion Price is subject to adjustment from time to time pursuant to the terms of the Certificate of Designation (the “Series B Certificate of Designation”).   If at the time of conversion, there are any authorized, declared and unpaid dividends with respect to a converted share of Series B Preferred Stock, the holder will receive cash in lieu of the dividends, and a holder will receive cash in lieu of fractional shares of common stock following conversion.
	After November 16, 2014, the Company may, at its option but subject to the Company’s receipt of any required prior approvals from the Board of Governors of the Federal Reserve System or any other regulatory authority, redeem the Series B Preferred Stock.  Any redemption will be in exchange for cash in the amount of $5,000 per share, plus any authorized, declared and unpaid dividends, without accumulation of any undeclared dividends.
	The Company also has the right at any time on or after November 16, 2014 to require the conversion of all (but not less than all) of the Series B Preferred Stock into shares of common stock if, on the date notice of mandatory conversion is given to holders, the book value of the Company’s common stock equals or exceeds 115% of the book value of the Company’s common stock at September 30, 2008. “Book value of the Company’s common stock” at any date means the result of dividing the Company’s total common stockholders’ equity at that date, determined in accordance with U.S. generally accepted accounting principles, by the number of shares of common stock then outstanding, net of any shares held in the treasury.  The book value of the Company’s common stock at September 30, 2008 was $13.03, and 115% of this amount is approximately $14.98. The book value of the Company’s common stock at December 31, 2014 was $19.55.
	Pursuant to Section 3(j) of the Series B Certification of Designation, the conversion price for the Series B Preferred Stock, which was initially set at $21.94, was required to be adjusted if, among other things, the initial conversion price of any subsequently issued series of preferred stock was lower than the then current conversion price of the Series B Preferred Stock.  As a result of the Series C Preferred Stock (see below) having an initial conversion price of less than $21.94, the conversion price of the Series B Preferred Stock was adjusted pursuant to the terms of the Series B Certificate of Designation based on the amount of Series C Preferred Stock sold on February 11, 2011, March 2, 2011, May 13, 2011 and June 28, 2012.  The current conversion price of the Series B Preferred Stock, certified by the Company’s accountant pursuant to Section 3(j) of the Series B Certificate of Designation, is $21.62.
	On September 23, 2014, the Board of Directors of the Company approved the mandatory conversion of all of the Company's issued and outstanding 4,926 shares of Series B Preferred Stock into shares of the Company’s common stock. On September 24, 2014, notices were sent to the shareholders of the Series B Preferred Stock regarding the mandatory conversion. On November 17, 2014, the Company completed the mandatory conversion. The conversion ratio for each share of the Series B Preferred Stock was computed by dividing $5,000 (the issuance price per share of the Series B Preferred Stock) by $21.62. (the then current conversion price). The conversion ratio, therefore, was 231.267 shares of the Company's common stock for each share of Series B Preferred Stock. This resulted in the issuance of approximately 1,139,195 shares of common stock in the aggregate. As a result of the conversion, dividends ceased to accrue on the Series B Preferred Stock and certificates for shares of Series B Preferred Stock only represent the right to receive the appropriate number of shares of common stock, together with net accrued but unpaid dividends, and cash in lieu of fractional share interests.
	Series C Convertible Preferred Stock.  On February 11, 2011, the Company accepted from certain accredited investors, including directors, executive officers, and certain major customers and holders of the Company’s common stock (collectively, the “Investors”), subscriptions for the purchase of $27,500,000, in the aggregate, of a newly authorized series of preferred stock designated as Series C 8% Non-Cumulative Perpetual Convertible Preferred Stock (the “Series C Preferred Stock”). As of February 11, 2011, $11,010,000 of the Series C Preferred Stock had been issued and sold by the Company to certain Investors.  On March 2, 2011, three investors subsequently completed the required bank regulatory process and an additional $2,750,000 of Series C Preferred Stock was issued and sold by the Company to these investors. On May 13, 2011, four additional investors received the required bank regulatory approval and an additional $5,490,000 of Series C Preferred Stock was issued and sold by the Company to these investors. On June 28, 2012, the final $8,250,000 of the Company’s Series C Preferred Stock was issued and sold by the Company to Investors following their receipt of the required bank regulatory approval, for a total of $27,500,000 of outstanding Series C Preferred Stock. All of the Series C Preferred Stock subscribed for by investors has been issued.
	The Series C Preferred Stock has an issue price of $5,000 per share and no par value per share.  The Series C Preferred Stock was issued in a private placement exempt from registration pursuant to Regulation D of the Securities Act of 1933, as amended.
	The Series C Preferred Stock pays non-cumulative dividends semiannually in arrears, when, as and if authorized by the Board of Directors of the Company, at a rate of 8% per year.  Holders of the Series C Preferred Stock will have no voting rights, except with respect to certain fundamental changes in the terms of the Series C Preferred Stock and certain other matters.  In addition, if dividends on the Series C Preferred Stock are not paid in full for four dividend periods, whether consecutive or not, the holders of the Series C Preferred Stock, acting as a class with any other of the Company’s securities having similar voting rights, including the Company’s Series B Preferred Stock, will have the right to elect two directors to the Company’s Board of Directors.  The terms of office of these directors will end when the Company has paid or set aside for payment full semi-annual dividends for four consecutive dividend periods.
	Each share of the Series C Preferred Stock may be converted at any time at the option of the holder into shares of the Company’s common stock.  The number of shares of common stock into which each share of the Series C Preferred Stock is convertible is the $5,000 liquidation preference per share divided by the Conversion Price of $20.29.  The Conversion Price is subject to adjustment from time to time pursuant to the terms of the Series C Certificate of Designation.  If at the time of conversion, there are any authorized, declared and unpaid dividends with respect to a converted share of Series C Preferred Stock, the holder will receive cash in lieu of the dividends, and a holder will receive cash in lieu of fractional shares of common stock following conversion.
	After May 13, 2016 the Company may, at its option but subject to the Company’s receipt of any required prior approvals from the Board of Governors of the Federal Reserve System or any other regulatory authority, redeem the Series C Preferred Stock.  Any redemption will be in exchange for cash in the amount of $5,000 per share, plus any authorized, declared and unpaid dividends, without accumulation of any undeclared dividends.
	The Company also has the right at any time after May 13, 2016 to require the conversion of all (but not less than all) of the Series C Preferred Stock into shares of common stock if, on the date notice of mandatory conversion is given to holders, (a) the tangible book value per share of the Company’s common stock equals or exceeds 115% of the tangible book value per share of the Company’s common stock at December 31, 2010, and (b) the NASDAQ Bank Index (denoted by CBNK:IND) equals or exceeds 115% of the NASDAQ Bank Index at December 31, 2010.  “Tangible book value per share of our common stock” at any date means the result of dividing the Company’s total common stockholders equity at that date, less the amount of goodwill and intangible assets, determined in accordance with U.S. generally accepted accounting principles, by the number of shares of common stock then outstanding, net of any shares held in the treasury. The tangible book value of the Company’s common stock at December 31, 2010 was $9.38, and 115% of this amount is approximately $10.79. The NASDAQ Bank Index value at December 31, 2010 was 1,847.35 and 115% of this amount is approximately 2,124.45. The tangible book value of the Company’s common stock at December 31, 2014 was $15.63 and the NASDAQ Bank Index value at December 31, 2014 was 2,675.88.
	Treasury Stock
	Treasury stock is stated at cost. Cost is determined by the first-in, first-out method.
	Stock Incentive Awards
	At the Annual Meeting of Stockholders held May 23, 2007, the stockholders approved the First Mid-Illinois Bancshares, Inc. 2007 Stock Incentive Plan (“SI Plan”).  The SI Plan was implemented to succeed the Company’s 1997 Stock Incentive Plan, which had a ten-year term that expired October 21, 2007. The SI Plan is intended to provide a means whereby directors, employees, consultants and advisors of the Company and its subsidiaries may sustain a sense of proprietorship and personal involvement in the continued development and financial success of the Company and its subsidiaries, thereby advancing the interests of the Company and its stockholders.  Accordingly, directors and selected employees, consultants and advisors may be provided the opportunity to acquire shares of common stock of the Company on the terms and conditions established in the SI Plan. On September 27, 2011, the Board of Directors passed a resolution relating to the SI Plan whereby they authorized and approved the Executive Long-Term Incentive Plan (“LTIP”). The LTIP was implemented to provide methodology for granting Stock Awards and Stock Unit Awards to select senior executives of the Company or any Subsidiary.
	A maximum of 300,000 shares of common stock may be issued under the SI Plan.  Prior to December 31, 2008, the Company had awarded 59,500 shares as stock options under the SI plan.  There have been no stock options awarded since 2008. The Company awarded 19,377 shares, 14,054 shares and 15,162 shares during 2014, 2013 and 2012, respectively, as 50% Stock Awards and 50% Stock Unit Awards under the SI plan.

	During the third quarter of 2014, management evaluated its available-for-sale portfolio and transferred obligations of U.S. government corporations & agencies securities with a fair value of $53.6 million from available-for-sale to held-to-maturity to reduce price volatility. Management determined it has both the intent and ability to hold these securities to maturity. Transfers of investment securities into the held-to-maturity category from available-for-sale are made at fair value on the date of transfer. There were no gains or losses recognized as a result of this transfer. The related $1.4 million of unrealized holding loss that was included in the transfer is retained in the carrying value of the held-to-maturity securities and in other comprehensive income net of deferred taxes. These amounts are being amortized into net interest income over the remaining life of the related securities as a yield adjustment, resulting in no impact on future net income.
	Trust preferred securities at December 31, 2014, is one trust preferred pooled security issued by First Tennessee Financial (“FTN”). The unrealized loss of this security, which has a maturity of twenty-three years, is primarily due to its long-term nature, a lack of demand or inactive market for the security, and concerns regarding the underlying financial institutions that have issued the trust preferred security. See the heading “Trust Preferred Securities” below for further information regarding this security.
	Proceeds from sales of investment securities, realized gains and losses and income tax expense and benefit were as follows during the years ended December 31, 2014, 2013 and 2012 (in thousands):

U.S. Treasury Securities and Obligations of U.S. Government Corporations and Agencies. At December 31, 2014, there were 16 available-for-sale U.S. Treasury securities and obligations of U.S. government corporations and agencies with a fair value of $75,030,000 and unrealized losses of $1,312,000 in a continuous unrealized loss position for twelve months or more. There were no held-to-maturity U.S. Treasury securities and obligations of U.S. government corporations and agencies in a continuous unrealized loss position for twelve months or more. At December 31, 2013 there were no obligations of U.S. government corporations and agencies in a continuous unrealized loss position for twelve months or more. The increase in unrealized losses is due to the rise in interest rates that has occurred since the time the investments were purchased.
Obligations of states and political subdivisions.  At December 31, 2014 there were ten Obligations of states and political subdivisions with a fair value of $4,416,000 and unrealized losses of $94,000 in a continuous unrealized loss position for twelve months or more. At December 31, 2013, there were two Obligations of states and political subdivisions with a fair value of $808,000 and unrealized losses of $65,000 in a continuous unrealized loss position for twelve months or more. The increase in unrealized losses is due to the rise in interest rates that has occurred since the time the investments were purchased.
Mortgage-backed Securities: GSE Residential. At December 31, 2014 there were eleven mortgage-backed security with a fair value of $37,224,000 and unrealized losses of $802,000 in a continuous unrealized loss position for twelve months or more. At December 31, 2013, there was one mortgage-backed security with a fair value of $13,000 and unrealized losses of $109 in a continuous unrealized loss position for twelve months or more. The increase in unrealized losses is due to the rise in interest rates that has occurred since the time the investments were purchased.
Trust Preferred Securities. At December 31, 2014, there was one trust preferred security with a fair value of $364,000 and unrealized losses of $2,936,000 in a continuous unrealized loss position for twelve months or more. At December 31, 2013, there was one trust preferred securities with a fair value of $191,000 and unrealized losses of $3,461,000 in a continuous unrealized loss position for twelve months or more. These unrealized losses were primarily due to the long-term nature of the trust preferred securities, a lack of demand or inactive market for these securities, the impending change to the regulatory treatment of these securities, and concerns regarding the underlying financial institutions that have issued the trust preferred securities. The Company recorded no other-than-temporary impairment (OTTI) for these securities during 2014 or 2013.  Because the Company does not intend to sell the remaining security and it is not more-likely-than-not that the Company will be required to sell this securities before recovery of its amortized cost basis, which may be maturity, the Company does not consider the remainder of the investment in this security to be other-than-temporarily impaired at December 31, 2014. However, future downgrades or additional deferrals and defaults in the security could result in additional OTTI and consequently, have a material impact on future earnings.
On July 22, 2013, the Company sold its holdings in PreTSL I and PreTSL II and the net proceeds exceeded the aggregate book value of the securities by approximately $1.4 million. On July 3, 2012, the Company’s holding in PreTSL VI was redeemed in full and the payment received exceeded the aggregate book of the security by approximately $139,000.
Following are the details for the impaired trust preferred security remaining as of December 31, 2014 (in thousands):
	Book			Market Value			Unrealized Gains (Losses)			Other-than-
	Value									temporary
										Impairment
										Recorded To-date
PreTSL XXVIII	$	3,300		$	364		$	(2,936	)	$	(1,111	)
Other securities. At December 31, 2014 and 2013, there were no corporate bonds in a continuous unrealized loss position for twelve months or more.
The Company does not believe any other individual unrealized loss as of December 31, 2014 represents OTTI. However, given the continued disruption in the financial markets, the Company may be required to recognize OTTI losses in future periods with respect to its available for sale investment securities portfolio. The amount and timing of any additional OTTI will depend on the decline in the underlying cash flows of the securities. Should the impairment of any of these securities become other-than-temporary, the cost basis of the investment will be reduced and the resulting loss recognized in the period the other-than-temporary impairment is identified.
Other-than-temporary Impairment
Upon acquisition of a security, the Company determines whether it is within the scope of the accounting guidance for investments in debt and equity securities or whether it must be evaluated for impairment under the accounting guidance for beneficial interests in securitized financial assets
The Company conducts periodic reviews to evaluate its investment securities to determine whether OTTI has occurred. While all securities are considered, the securities primarily impacted by OTTI evaluation are pooled trust preferred securities. For the pooled trust preferred security currently in the investment portfolio, an extensive review is conducted to determine if any additional OTTI has occurred. The Company utilizes an independent third-party to perform the OTTI evaluation. The Company's management reviews the assumption inputs and methodology with the third-party to obtain an understanding of them and determine if they are appropriate for the evaluation. Economic models are used to project future cash flows for the security based on current assumptions for discount rate, prepayments, default and deferral rates and recoveries. These assumptions are determined based on the structure of the issuance, the specific collateral underlying the security, historical performance of trust preferred securities and general state of the economy. The OTTI test compares the present value of the cash flows from quarter to quarter to determine if there has been an adverse change which could indicate additional OTTI.
The discount rate assumption used in the cash flow model is equal to the current yield used to accrete the beneficial interest. The Company’s current trust preferred security investment has a floating rate coupon of 3-month LIBOR plus 90 basis points. Since the estimate of 3-month LIBOR is based on the forward curve on the measurement date, and is therefore variable, the discount assumption for this security is a range of projected coupons over the expected life of the security.
The Company considers the likelihood that issuers will prepay their securities which changes the amount of expected cash flows. Factors such as the coupon rates of collateral, economic conditions and regulatory changes, such as the Dodd-Frank Act and Basel III, are considered.
The trust preferred security includes collateral issued by financial institutions and insurance companies. To identify bank issuers with a high risk of near term default or deferral, a credit model developed by the third-party is utilized that scores each bank issuer based on 29 different ratios covering capital adequacy, asset quality, earnings, liquidity, the Texas Ratio, and sensitivity to interest rates. To account for longer term bank default risk not captured by the credit model, it is assumed that banks will default at a rate of 2% annually for the first two years of the cash flow projection, and 36 basis points in each year thereafter. To project defaults for insurance issuers, each issuer’s credit rating is mapped to its idealized default rate, which is AM Best’s estimate of the historical default rate for insurance companies with that rating.
Lastly, it is assumed that trust preferred securities issued by banks that have already failed will have no recoveries, and that banks projected to default will have recoveries of 10%. Additionally, the 10% recovery assumption, incorporates the potential for cures by banks that are currently in deferral.
If the Company determines that a given pooled trust preferred security position will be subject to a write-down or loss, the Company records the expected credit loss as a charge to earnings.
Credit Losses Recognized on Investments
As described above, some of the Company’s investments in trust preferred securities have experienced fair value deterioration due to credit losses but are not otherwise other-than-temporarily impaired. The following table provides information about those trust preferred securities for which only a credit loss was recognized in income and other losses are recorded in other comprehensive income (loss) for the years ended December 31, 2014, 2013 and 2012 (in thousands).

Loans and Allowance for Loan Losses	12 Months Ended
	Dec. 31, 2014
Receivables [Abstract]
Loans and Allowance for Loan Losses	Loans are stated at the principal amount outstanding net of unearned discounts, unearned income and allowance for loan losses.  Unearned income includes deferred loan origination fees reduced by loan origination costs and is amortized to interest income over the life of the related loan using methods that approximated the effective interest rate method.  Interest on substantially all loans is credited to income based on the principal amount outstanding. A summary of loans at December 31, 2014 and 2013 follows (in thousands):
		2014				2013
	Construction and land development	$	21,627			$	25,321

	Allowance for loan losses	13,682				13,249
	Net loans	$	1,046,766			$	969,041
	Loans expected to be sold are classified as held for sale in the consolidated financial statements and are recorded at the lower of aggregate cost or market value, taking into consideration future commitments to sell the loans. These loans are primarily for 1-4 family residential properties. The balance of loans held for sale, excluded from the balances above, were $1,958,000 and $514,000 at December 31, 2014 and 2013, respectively.
	Most of the Company’s business activities are with customers located within central Illinois.  At December 31, 2014, the Company’s loan portfolio included $178.5 million of loans to borrowers whose businesses are directly related to agriculture. Of this amount, $155.1 million was concentrated in other grain farming. Total loans to borrowers whose businesses are directly related to agriculture increased $5.0 million from $173.5 million at December 31, 2013 while loans concentrated in other grain farming increased $8.0 million from $147.1 million at December 31, 2013.  While the Company adheres to sound underwriting practices, including collateralization of loans, any extended period of low commodity prices, drought conditions, significantly reduced yields on crops and/or reduced levels of government assistance to the agricultural industry could result in an increase in the level of problem agriculture loans and potentially result in loan losses within the agricultural portfolio.
	In addition, the Company has $56.5 million of loans to motels and hotels.  The performance of these loans is dependent on borrower specific issues as well as the general level of business and personal travel within the region.  While the Company adheres to sound underwriting standards, a prolonged period of reduced business or personal travel could result in an increase in nonperforming loans to this business segment and potentially in loan losses. The Company also has $46.2 million of loans to other general merchandise stores, $96.5 million of loans to lessors of non-residential buildings and $65.8 million of loans to lessors of residential buildings and dwellings.
	The structure of the Company’s loan approval process is based on progressively larger lending authorities granted to individual loan officers, loan committees, and ultimately the Board of Directors.  Outstanding balances to one borrower or affiliated borrowers are limited by federal regulation; however, limits well below the regulatory thresholds are generally observed.  The vast majority of the Company’s loans are to businesses located in the geographic market areas served by the Company’s branch bank system.  Additionally, a significant portion of the collateral securing the loans in the portfolio is located within the Company’s primary geographic footprint.  In general, the Company adheres to loan underwriting standards consistent with industry guidelines for all loan segments. The Company’s lending can be summarized into the following primary areas:
	Commercial Real Estate Loans.  Commercial real estate loans are generally comprised of loans to small business entities to purchase or expand structures in which the business operations are housed, loans to owners of real estate who lease space to non-related commercial entities, loans for construction and land development, loans to hotel operators, and loans to owners of multi-family residential structures, such as apartment buildings.  Commercial real estate loans are underwritten based on historical and projected cash flows of the borrower and secondarily on the underlying real estate pledged as collateral on the debt.  For the various types of commercial real estate loans, minimum criteria have been established within the Company’s loan policy regarding debt service coverage while maximum limits on loan-to-value and amortization periods have been defined.  Maximum loan-to-value ratios range from 65% to 80% depending upon the type of real estate collateral, while the desired minimum debt coverage ratio is 1.20x. Amortization periods for commercial real estate loans are generally limited to twenty years. The Company’s commercial real estate portfolio is well below the thresholds that would designate a concentration in commercial real estate lending, as established by the federal banking regulators.
	Commercial and Industrial Loans. Commercial and industrial loans are primarily comprised of working capital loans used to purchase inventory and fund accounts receivable that are secured by business assets other than real estate.  These loans are generally written for one year or less. Also, equipment financing is provided to businesses with these loans generally limited to 80% of the value of the collateral and amortization periods limited to seven years. Commercial loans are often accompanied by a personal guaranty of the principal owners of a business.  Like commercial real estate loans, the underlying cash flow of the business is the primary consideration in the underwriting process.  The financial condition of commercial borrowers is monitored at least annually with the type of financial information required determined by the size of the relationship.  Measures employed by the Company for businesses with higher risk profiles include the use of government-assisted lending programs through the Small Business Administration and U.S. Department of Agriculture.
	Agricultural and Agricultural Real Estate Loans. Agricultural loans are generally comprised of seasonal operating lines to cash grain farmers to plant and harvest corn and soybeans and term loans to fund the purchase of equipment.  Agricultural real estate loans are primarily comprised of loans for the purchase of farmland.  Specific underwriting standards have been established for agricultural-related loans including the establishment of projections for each operating year based on industry developed estimates of farm input costs and expected commodity yields and prices.  Operating lines are typically written for one year and secured by the crop. Loan-to-value ratios on loans secured by farmland generally do not exceed 65% and have amortization periods limited to twenty five years.  Federal government-assistance lending programs through the Farm Service Agency are used to mitigate the level of credit risk when deemed appropriate.
	Residential Real Estate Loans. Residential real estate loans generally include loans for the purchase or refinance of residential real estate properties consisting of one-to-four units and home equity loans and lines of credit.  The Company sells the vast majority of its long-term fixed rate residential real estate loans to secondary market investors.  The Company also releases the servicing of these loans upon sale.  The Company retains all residential real estate loans with balloon payment features.  Balloon periods are limited to five years. Residential real estate loans are typically underwritten to conform to industry standards including criteria for maximum debt-to-income and loan-to-value ratios as well as minimum credit scores.  Loans secured by first liens on residential real estate held in the portfolio typically do not exceed 80% of the value of the collateral and have amortization periods of twenty five years or less. The Company does not originate subprime mortgage loans.
	Consumer Loans. Consumer loans are primarily comprised of loans to individuals for personal and household purposes such as the purchase of an automobile or other living expenses.  Minimum underwriting criteria have been established that consider credit score, debt-to-income ratio, employment history, and collateral coverage.  Typically, consumer loans are set up on monthly payments with amortization periods based on the type and age of the collateral.
	Other Loans. Other loans consist primarily of loans to municipalities to support community projects such as infrastructure improvements or equipment purchases.  Underwriting guidelines for these loans are consistent with those established for commercial loans with the additional repayment source of the taxing authority of the municipality.
	Allowance for Loan Losses
	The allowance for loan losses represents the Company’s best estimate of the reserve necessary to adequately account for probable losses existing in the current portfolio. The provision for loan losses is the charge against current earnings that is determined by the Company as the amount needed to maintain an adequate allowance for loan losses. In determining the adequacy of the allowance for loan losses, and therefore the provision to be charged to current earnings, the Company relies predominantly on a disciplined credit review and approval process that extends to the full range of the Company’s credit exposure.  The review process is directed by the overall lending policy and is intended to identify, at the earliest possible stage, borrowers who might be facing financial difficulty.  Once identified, the magnitude of exposure to individual borrowers is quantified in the form of specific allocations of the allowance for loan losses.  The Company considers collateral values and guarantees in the determination of such specific allocations. Additional factors considered by the Company in evaluating the overall adequacy of the allowance include historical net loan losses, the level and composition of nonaccrual, past due and troubled debt restructurings, trends in volumes and terms of loans, effects of changes in risk selection and underwriting standards or lending practices, lending staff changes, concentrations of credit, industry conditions and the current economic conditions in the region where the Company operates.
	The Company estimates the appropriate level of allowance for loan losses by separately evaluating large impaired loans, large adversely classified loans and nonimpaired loans.
	Impaired loans. The Company individually evaluates certain loans for impairment.  In general, these loans have been internally identified via the Company’s loan grading system as credits requiring management’s attention due to underlying problems in the borrower’s business or collateral concerns.  This evaluation considers expected future cash flows, the value of collateral and also other factors that may impact the borrower’s ability to make payments when due.  For loans greater than $100,000 in the commercial, commercial real estate, agricultural, agricultural real estate segments, impairment is individually measured each quarter using one of three alternatives: (1) the present value of expected future cash flows discounted at the loan’s effective interest rate; (2) the loan’s observable market price, if available; or (3) the fair value of the collateral less costs to sell for collateral dependent loans and loans for which foreclosure is deemed to be probable. A specific allowance is assigned when expected cash flows or collateral do not justify the carrying amount of the loan. The carrying value of the loan reflects reductions from prior charge-offs.
	Adversely classified loans. A detailed analysis is also performed on each adversely classified (substandard or doubtful rated) borrower with an aggregate, outstanding balance of $100,000 or more. This analysis includes commercial, commercial real estate, agricultural, and agricultural real estate borrowers who are not currently identified as impaired but pose sufficient risk to warrant in-depth review. Estimated collateral shortfalls are then calculated with allocations for each loan segment based on the five-year historical average of collateral shortfalls adjusted for environmental factors including changes in economic conditions, changes in credit policies or underwriting standards, and changes in the level of credit risk associated with specific industries and markets. Because the economic and business climate in any given industry or market, and its impact on any given borrower, can change rapidly, the risk profile of the loan portfolio is periodically assessed and adjusted when appropriate.
	Non-classified and Watch loans. For loans, in all segments of the portfolio, that are considered to possess levels of risk commensurate with a pass rating, management establishes base loss estimations which are derived from historical loss experience.  Use of a five-year historical loss period eliminates the effect of any significant losses that can be attributed to a single event or borrower during a given reporting period. The base loss estimations for each loan segment are adjusted after consideration of several environmental factors influencing the level of credit risk in the portfolio. In addition, loans rated as watch are further segregated in the commercial / commercial real estate and agricultural / agricultural real estate segments. These loans possess potential weaknesses that, if unchecked, may result in deterioration to the point of becoming a problem asset.  Due to the elevated risk inherent in these loans, an allocation of twice the adjusted base loss estimation of the applicable loan segment is determined appropriate.
	Due to weakened economic conditions during recent years, the Company established allocations for each of the loan segments at levels above the base loss estimations. Some of the economic factors included the potential for reduced cash flow for commercial operating loans from reduction in sales or increased operating costs, decreased occupancy rates for commercial buildings, reduced levels of home sales for commercial land developments, the uncertainty regarding grain prices and increased operating costs for farmers, and increased levels of unemployment and bankruptcy impacting consumer’s ability to pay. Each of these economic uncertainties was taken into consideration in developing the level of the reserve. The Company has not materially changed any aspect of its overall approach in the determination of the allowance for loan losses.  However, on an on-going basis the Company continues to refine the methods used in determining management’s best estimate of the allowance for loan losses.

Consistent with regulatory guidance, charge-offs on all loan segments are taken when specific loans, or portions thereof, are considered uncollectible. The Company’s policy is to promptly charge these loans off in the period the uncollectible loss is reasonably determined.
For all loan portfolio segments except 1-4 family residential properties and consumer, the Company promptly charges-off loans, or portions thereof, when available information confirms that specific loans are uncollectible based on information that includes, but is not limited to, (1) the deteriorating financial condition of the borrower, (2) declining collateral values, and/or (3) legal action, including bankruptcy, that impairs the borrower’s ability to adequately meet its obligations. For impaired loans that are considered to be solely collateral dependent, a partial charge-off is recorded when a loss has been confirmed by an updated appraisal or other appropriate valuation of the collateral.
The Company charges-off 1-4 family residential and consumer loans, or portions thereof, when the Company reasonably determines the amount of the loss. The Company adheres to timeframes established by applicable regulatory guidance which provides for the charge-down of 1-4 family first and junior lien mortgages to the net realizable value less costs to sell when the loan is 180 days past due, charge-off of unsecured open-end loans when the loan is 180 days past due, and charge down to the net realizable value when other secured loans are 120 days past due. Loans at these respective delinquency thresholds for which the Company can clearly document that the loan is both well-secured and in the process of collection, such that collection will occur regardless of delinquency status, need not be charged off.
Credit Quality
The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as:  current financial information, historical payment experience, collateral support, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes loans with an outstanding balance greater than $100,000 and non-homogeneous loans, such as commercial and commercial real estate loans.  This analysis is performed on a continuous basis. The Company uses the following definitions for risk ratings:
Watch. Loans classified as watch have a potential weakness that deserves management’s close attention.  If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.
Substandard. Loans classified as substandard are inadequately protected by the current sound-worthiness and paying capacity of the obligor or of the collateral pledged, if any.  Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.
Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing factors, conditions and values, highly questionable and improbable.
Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered pass rated loans. The following tables present the credit risk profile of the Company’s loan portfolio based on rating category and payment activity as of December 31, 2014 and 2013 (in thousands):

Impaired Loans
Within all loan portfolio segments, loans are considered impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. The entire balance of a loan is considered delinquent if the minimum payment contractually required to be made is not received by the specified due date. Impaired loans, excluding certain troubled debt restructured loans, are placed on nonaccrual status. Impaired loans include nonaccrual loans and loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties.  These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. It is the Company’s policy to have any restructured loans which are on nonaccrual status prior to being modified remain on nonaccrual status until, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collection of interest or principal. If the restructured loan is on accrual status prior to being modified, the loan is reviewed to determine if the modified loan should remain on accrual status.

The Company’s policy is to discontinue the accrual of interest income on all loans for which principal or interest is ninety days past due.  The accrual of interest is discontinued earlier when, in the opinion of management, there is reasonable doubt as to the timely collection of interest or principal.  Once interest accruals are discontinued, accrued but uncollected interest is charged against current year income. Subsequent receipts on non-accrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured. Interest on loans determined to be troubled debt restructurings is recognized on an accrual basis in accordance with the restructured terms if the loan is in compliance with the modified terms.  Nonaccrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collection of interest or principal. The Company requires a period of satisfactory performance of not less than six months before returning a nonaccrual loan to accrual status.

The aggregate principal balances of nonaccrual, past due ninety days or more loans were $4.1 million and $6.1 million at December 31, 2014 and 2013, respectively. Interest income that would have been recorded under the original terms of such nonaccrual loans totaled $71,000, $45,000 and $173,000 in 2014, 2013 and 2012, respectively.
Troubled Debt Restructuring
The balance of troubled debt restructurings ("TDRs") at December 31, 2014 and 2013 was $2,860,000 and $3,200,000, respectively.  Approximately $234,000 and $431,000 in specific reserves have been established with respect to these loans as of December 31, 2014 and 2013, respectively. As troubled debt restructurings, these loans are included in nonperforming loans and are classified as impaired which requires that they be individually measured for impairment. The modification of the terms of these loans included one or a combination of the following: a reduction of stated interest rate of the loan; an extension of the maturity date and change in payment terms; or a permanent reduction of the recorded investment in the loan.
The following table presents the Company’s recorded balance of troubled debt restructurings at December 31, 2014 and 2013 (in thousands).

	At December 31, 2014 and 2013, there was no outstanding loan balance on a revolving credit agreement with The Northern Trust Company. This loan was renewed on April 18, 2014. The revolving credit agreement has a maximum available balance of $15 million with a term of one year from the date of closing. The interest rate (2.5% at December 31, 2013) is floating at 2.25% over the federal funds rate. The loan is unsecured and subject to a borrowing agreement containing requirements for the Company and First Mid Bank to maintain various operating and capital ratios. The Company and First Mid Bank were in compliance with all the existing covenants at December 31, 2014 and 2013.
	On February 27, 2004, the Company completed the issuance and sale of $10 million of floating rate trust preferred securities through Trust I, a statutory business trust and wholly-owned unconsolidated subsidiary of the Company, as part of a pooled offering.  The Company established Trust I for the purpose of issuing the trust preferred securities.  The $10 million in proceeds from the trust preferred issuance and an additional $310,000 for the Company’s investment in common equity of the Trust, a total of $10,310,000, was invested in junior subordinated debentures of the Company.  The underlying junior subordinated debentures issued by the Company to Trust I mature in 2034, bear interest at three-month London Interbank Offered Rate (“LIBOR”) plus 280 basis points, reset quarterly, and are callable, at the option of the Company, at par on or after April 7, 2009. At December 31, 2014 and 2013 the rate was 3.08% and 3.09%, respectively. The Company used the proceeds of the offering for general corporate purposes.
	On April 26, 2006, the Company completed the issuance and sale of $10 million of fixed/floating rate trust preferred securities through Trust II, a statutory business trust and wholly-owned unconsolidated subsidiary of the Company, as part of a pooled offering.  The Company established Trust II for the purpose of issuing the trust preferred securities. The $10 million in proceeds from the trust preferred issuance and an additional $310,000 for the Company’s investment in common equity of Trust II, a total of $10,310,000, was invested in junior subordinated debentures of the Company.  The underlying junior subordinated debentures issued by the Company to Trust II mature in 2036, bore interest at a fixed rate of 6.98% paid quarterly until June 15, 2011 and then converted to floating rate (LIBOR plus 160 basis points) after June 15, 2011 (1.84% and 1.84% at December 31, 2014 and 2013). The net proceeds to the Company were used for general corporate purposes, including the Company’s acquisition of Mansfield.
	The trust preferred securities issued by Trust I and Trust II are included as Tier 1 capital of the Company for regulatory capital purposes.  On March 1, 2005, the Federal Reserve Board adopted a final rule that allows the continued limited inclusion of trust preferred securities in the calculation of Tier 1 capital for regulatory purposes.  The final rule provided a five-year transition period, ending September 30, 2010, for application of the revised quantitative limits. On March 17, 2009, the Federal Reserve Board adopted an additional final rule that delayed the effective date of the new limits on inclusion of trust preferred securities in the calculation of Tier 1 capital until September 30, 2011. The Company does not expect the application of the revised quantitative limits to have a significant impact on its calculation of Tier 1 capital for regulatory purposes or its classification as well-capitalized. The Dodd-Frank Act, signed into law July 21, 2010, removes trust preferred securities as a permitted component of a holding company’s Tier 1 capital after a three-year phase-in period beginning January 1, 2013 for larger holding companies. For holding companies with less than $15 billion in consolidated assets, existing issues of trust preferred securities are grandfathered and not subject to this new restriction. Therefore, the existing trust preferred securities issued by Trust I and Trust II will continue to count as Tier I capital. New issuances of trust preferred securities, however would not count as Tier 1 regulatory capital.

Regulatory Capital Requirements [Abstract]
Regulatory Capital Requirements under Banking Regulations [Text Block]	Regulatory Capital
	The Company is subject to various regulatory capital requirements administered by the federal banking agencies.  Bank holding companies follow minimum regulatory requirements established by the Board of Governors of the Federal Reserve System (“Federal Reserve System”), and First Mid Bank follows similar minimum regulatory requirements established for national banks by the Office of the Comptroller of the Currency (“OCC”).  Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary action by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements.
	Quantitative measures established by each regulatory agency to ensure capital adequacy require the reporting institutions to maintain a minimum total risk-based capital ratio of 8%, a minimum Tier 1 risk-based capital ratio of 4% and a minimum leverage ratio of 3% for the most highly rated banks that do not expect significant growth.  All other institutions are required to maintain a minimum leverage ratio of 4%.  Management believes that, as of December 31, 2014 and 2013, the Company and First Mid Bank met all capital adequacy requirements.
	As of December 31, 2014 and 2013, the most recent notification from the primary regulators categorized First Mid Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios must be maintained as set forth in the table below. At December 31, 2014, there were no conditions or events since the most recent notification that management believes have changed this categorization.

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	Fair value is 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.  Fair value measurements must maximize the use of observable inputs and minimize the use of unobservable inputs.  There is a hierarchy of three levels of inputs that may be used to measure fair value:
	Level 1	Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange.  Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.
	Level 2	Valuations for assets and liabilities traded in less active dealer or broker markets.  Valuations are obtained from third party pricing services for identical or comparable assets or liabilities which use observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in active markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	Following is a description of the inputs and valuation methodologies used for assets measured at fair value on a recurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy.
	Available-for-Sale Securities. The fair value of available-for-sale securities is determined by various valuation methodologies.  Where quoted market prices are available in an active market, securities are classified within Level 1. If quoted market prices are not available, then fair values are estimated by using quoted prices of securities with similar characteristics or independent asset pricing services and pricing models, the inputs of which are market-based or independently sources market parameters, including but not limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections and cash flows.  Such securities are classified in Level 2 of the valuation hierarchy. In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy and include subordinated tranches of collateralized mortgage obligations and investments in trust preferred securities.
	Fair value determinations for Level 3 measurements of securities are the responsibility of the Treasury function of the Company.  The Company contracts with a pricing specialist to generate fair value estimates on a monthly basis.  The Treasury function of the Company challenges the reasonableness of the assumptions used and reviews the methodology to ensure the estimated fair value complies with accounting standards generally accepted in the United States, analyzes the changes in fair value and compares these changes to internally developed expectations and monitors these changes for appropriateness.
	The trust preferred securities are collateralized debt obligation securities that are backed by trust preferred securities issued by banks, thrifts, and insurance companies. The market for these securities at December 31, 2014 is not active and markets for similar securities are also not active. The inactivity was evidenced first by a significant widening of the bid-ask spread in the brokered markets in which trust preferred securities trade and then by a significant decrease in the volume of trades relative to historical levels. The new issue market is also inactive and will continue to be, as a result of the Dodd-Frank Act’s elimination of trust preferred securities from Tier 1 capital for certain holding companies. There are currently very few market participants who are willing and or able to transact for these securities. The market values for these securities are very depressed relative to historical levels.
	Given conditions in the debt markets today and the absence of observable transactions in the secondary and new issue markets, we determined:
	•	The few observable transactions and market quotations that are available are not reliable for purposes of determining fair value at December 31, 2014,
	•	An income valuation approach technique (present value technique) that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs will be equally or more representative of fair value than the market approach valuation technique used at prior measurement dates, and
	•	The trust preferred securities held by the Company will be classified within Level 3 of the fair value hierarchy because we determined that significant adjustments are required to determine fair value at the measurement date.
	The following table presents the Company’s assets that are measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall as of December 31, 2014 and 2013 (in thousands):

	Following is a description of the valuation methodologies used for assets measured at fair value on a nonrecurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy.
	Impaired Loans (Collateral Dependent)
	Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured for impairment.  Allowable methods for determining the amount of impairment and estimating fair value include using the fair value of the collateral for collateral dependent loans.
	If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. Impaired loans that are collateral dependent are classified within Level 3 of the fair value hierarchy when impairment is determined using the fair value method.
	Management establishes a specific allowance for loans that have an estimated fair value that is below the carrying value. The total carrying amount of loans for which a specific allowance has been established as of December 31, 2014 was $1,576,000 and a fair value of $1,313,000 resulting in specific loss exposures of $263,000. As of December 31, 2013, the total carrying amount of loans for which a specific reserve had been established was $1,987,000. These loans had a fair value of $1,383,000 which resulted in specific loss exposures of $604,000.
	When there is little prospect of collecting principal or interest, loans, or portions of loans, may be charged-off to the allowance for loan losses.  Losses are recognized in the period an obligation becomes uncollectible.  The recognition of a loss does not mean that the loan has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off the loan even though partial recovery may be affected in the future.
	Foreclosed Assets Held For Sale
	Other real estate owned acquired through loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. The adjustment at the time of foreclosure is recorded through the allowance for loan losses. Due to the subjective nature of establishing the fair value when the asset is acquired, the actual fair value of the other real estate owned or foreclosed asset could differ from the original estimate. If it is determined that fair value declines subsequent to foreclosure, a valuation allowance is recorded through noninterest expense. Operating costs associated with the assets after acquisition are also recorded as noninterest expense. Gains and losses on the disposition of other real estate owned and foreclosed assets are netted and posted to other noninterest expense. The total carrying amount of other real estate owned as of December 31, 2014 was $263,000. Other real estate owned included in the total carrying amount and measured at fair value on a nonrecurring basis during the period amounted to $0. The total carrying amount of other real estate owned as of December 31, 2013 was $568,000. Other real estate owned included in the total carrying amount and measured at fair value on a nonrecurring basis during the period amounted to $172,000.
	The following table presents the fair value measurement of assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at December 31, 2014 and 2013 (in thousands):

Sensitivity of Significant Unobservable Inputs
The following is a discussion of the sensitivity of significant unobservable inputs, the interrelationships between those inputs and other unobservable inputs used in recurring fair value measurement and of how those inputs might magnify or mitigate the effect of changes in the unobservable inputs on the fair value measurement.
Trust Preferred Securities. The significant unobservable inputs used in the fair value measurement of the Company’s trust preferred securities are offered quotes and comparability adjustments.  Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value measurement.  Generally, changes in either of those inputs will not affect the other input.
The following table presents quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements other than goodwill at December 31, 2014.
	Fair Value (in thousands)				Valuation Technique		Unobservable Inputs	Range (Weighted Average)

Other. The following methods were used to estimate the fair value of all other financial instruments recognized in the accompanying balance sheets at amounts other than fair value.
Cash and Cash Equivalents, Interest Receivable, Federal Reserve and Federal Home Loan Bank Stock
The carrying amount approximates fair value.
Held-to-Maturity Securities
Fair Value is based on quoted market prices, if available. If a quoted market price is not available, fair value is estimated using quoted
market prices for similar securities.
Loans
For loans with floating interest rates, it is assumed that the estimated fair values generally approximate the carrying amount balances.  Fixed rate loans have been valued using a discounted present value of projected cash flow. The discount rate used in these calculations is the current rate at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.  The carrying amount of accrued interest approximates its fair value.
Deposits
Deposits include demand deposits, savings accounts, NOW accounts and certain money market deposits. The carrying amount of these deposits approximates fair value. The fair value of fixed-maturity time deposits is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities.
Securities Sold Under Agreements to Repurchase
The fair value of securities sold under agreements to repurchased is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities.
Interest Payable
The carrying amount approximates fair value.
Subordinated Debentures and Federal Home Loan Bank Advances
Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt.

Deferred Compensation Plan	Deferred Compensation Plan
	The Company follows the provisions of ASC 710, for purposes of the First Mid-Illinois Bancshares, Inc. Deferred Compensation Plan (“DCP”).  At December 31, 2014, the Company classified the cost basis of its common stock issued and held in trust in connection with the DCP of approximately $3,539,000 as treasury stock.  The Company also classified the cost basis of its related deferred compensation obligation of approximately $3,539,000 as an equity instrument (deferred compensation).
	The DCP was effective as of June 1984. The purpose of the DCP is to enable directors, advisory directors, and key employees the opportunity to defer a portion of the fees and cash compensation paid by the Company as a means of maximizing the effectiveness and flexibility of compensation arrangements.  The Company invests all participants’ deferrals in shares of common stock. Dividends paid on the shares are credited to participants’ DCP accounts and invested in additional shares.  During 2014 and 2013 the Company issued 13,724 common shares and 12,700 common shares, respectively, pursuant to the DCP.

Stock Incentive Plan	Stock Incentive Plan
	At the Annual Meeting of Stockholders held May 23, 2007, the stockholders approved the First Mid-Illinois Bancshares, Inc. 2007 Stock Incentive Plan (“SI Plan”).  The SI Plan was implemented to succeed the Company’s 1997 Stock Incentive Plan, which had a ten-year term that expired October 21, 2007, under which there are still options outstanding. The SI Plan is intended to provide a means whereby directors, employees, consultants and advisors of the Company and its subsidiaries may sustain a sense of proprietorship and personal involvement in the continued development and financial success of the Company and its subsidiaries, thereby advancing the interests of the Company and its stockholders.  Accordingly, directors and selected employees, consultants and advisors may be provided the opportunity to acquire shares of Common Stock of the Company on the terms and conditions established in the SI Plan.
	On September 27, 2011, the Board of Directors passed a resolution authorizing and approving the Executive Long-Term Incentive Plan (“LTIP”). The LTIP was implemented to provide methodology for granting Stock Awards and Stock Unit Awards under the SI Plan to select senior executives of the Company or any subsidiary.
	A maximum of 300,000 shares are authorized under the SI Plan. This amount reflects the Company’s stock split which occurred on June 29, 2007. Options to acquire shares are awarded at an exercise price equal to the fair market value of the shares on the date of grant and have a 10-year term.  Options granted to employees vested over a four-year period and options granted to directors vested at the time they were issued. Prior to December 31, 2008, the Company had awarded 59,500 shares as stock options under the SI Plan. During 2014, 2013 and 2012, the Company awarded 19,377 shares, 14,054 shares and 15,162 shares, respectively as 50% Stock Awards and 50% Stock Unit Awards under the LTIP of the SI Plan.
	The fair value of options granted was estimated on the grant date using the Black-Scholes option-pricing model. Expected volatility was based on historical volatility of the Company’s stock and other factors.  The Company used historical data to estimate option exercises and employee termination within the valuation model; separate groups of employees who had similar historical exercise behavior were considered separately for valuation purposes.  The expected term of options granted was derived from the output of the option valuation model and represented the period of time that options granted were expected to be outstanding.  The risk-free rate for periods within the contractual life of the option was based on the U.S. Treasury yield curve in effect at the time of the grant. There were no options granted during 2014, 2013 or 2012.
	The following table summarizes the compensation cost, net of forfeitures, related to stock-based compensation for the years ended December 31, 2014, 2013 and 2012:

The following table summarizes information about stock options under the SI Plan outstanding at December 31, 2014:
			Options Outstanding				Options Exercisable

	52,000		3.43		$24.64		52,000		$24.64
In September 2011, as part of the LTIP approval, the Board approved a form of Stock Award/Stock Unit Award Agreement and a form of Stock Unit Award Agreement.  These forms set forth the terms and conditions of the Stock Awards and Stock Units granted to participants in the Plan as part of their Annual Performance Award and Cumulative Performance Award.  Each of the Annual Performance Award and Cumulative Performance Award consists of Stock Awards (50%) and Stock Units (50%), except that Awards to retirement-eligible employees are made 100% in Stock Units.  The target number of shares subject to the Stock Awards and/or Stock Units is adjusted by the Board at the end of each applicable performance period based on the actual level of attainment of performance goals previously set by the Board.  The Annual Performance Award has a one-year performance period and vest over four years. The Cumulative Performance Award has a three-year performance period and vest at the end of the three-year period.  Stock Awards are settled in shares while Stock Units are settled in cash (although Stock Units held by retirement-eligible employees are settled half in shares and half in cash).  The following table summarizes non-vested stock and stock unit activity for the years ended December 31, 2014, 2013 and 2012:
	2014						2013					2012
	Shares		Weighted-avg Grant-date Fair Value				Shares		Weighted-avg Grant-date Fair Value			Shares	Weighted-avg Grant-date Fair Value
Nonvested, beginning of year	24,799		$24.16				25,337		$22.16			15,096	$18.70

Fair value of shares vested			$	343,910					$	329,721			$	91,259
The fair value of the awards is amortized to compensation expense over the vesting periods of the awards (four years for annual awards and three years for cumulative awards) and is based on the market price of the Company’s common stock at the date of grant multiplied by the number of shares granted that are expected to vest.  As of December 31, 2014, 2013 and 2012, there was $435,000, $470,000, and $400,000, respectively, of total unrecognized compensation cost related to unvested stock and stock unit awards under the SI.  That cost is expected to be recognized over the remaining three-year period.

	Recorded income tax expense differs from the expected tax expense (computed by applying the applicable statutory U.S. federal tax rate of 35% to income before income taxes).  During 2014, 2013 and 2012, the Company was in a graduated tax rate position.  The principal reasons for the difference are as follows:
		2014			2013			2012
	Expected income taxes	$	8,650		$	8,249		$	7,852
	Effects of:
	Tax-exempt income	(954		)	(877		)	(761		)

	Other items	43			36			41
	Total	$	9,254		$	8,846		$	8,410
	Tax expense recorded by the Company during 2014, 2013 and 2012 did not include any interest or penalties. Tax returns filed with the Internal Revenue Service and Illinois Department of Revenue are subject to review by law under a three-year statute of limitations. The Company is no longer subject to U.S. federal or state income tax examinations by tax authorities for years before 2011.
	The tax effects of the temporary differences that gave rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2014 and 2013 are presented below:
		2014			2013
	Deferred tax assets:
	Allowance for loan losses	$	5,522		$	5,348

Divididends Restrictions [Abstract]
Dividend Restrictions	Dividend Restrictions
	The National Bank Act imposes limitations on the amount of dividends that may be paid by a national bank, such as First Mid Bank.  Generally, a national bank may pay dividends out of its undivided profits, in such amounts and at such times as the bank’s board of directors deems prudent.  Without prior OCC approval, however, a national bank may not pay dividends in any calendar year which, in the aggregate, exceed the bank’s year-to-date net income plus the bank’s adjusted retained net income for the two preceding years. Factors that could adversely affect First Mid Bank’s net income include other-than-temporary impairment on investment securities that result in credit losses and economic conditions in industries where there are concentrations of loans outstanding that result in impairment of these loans and, consequently loan charges and the need for increased allowances for losses. See “Item 1A. Risk Factors,” Note 4 – “Investment Securities” and Note 5 – “Loans” for a more detailed discussion of the factors.
	The payment of dividends by any financial institution or its holding company is affected by the requirement to maintain adequate capital pursuant to applicable capital adequacy guidelines and regulations, and a financial institution generally is prohibited from paying any dividends if, following payment thereof, the institution would be undercapitalized.  As described above, First Mid Bank exceeded its minimum capital requirements under applicable guidelines as of December 31, 2014.  As of December 31, 2014, approximately $37.9 million was available to be paid as dividends to the Company by First Mid Bank.  Notwithstanding the availability of funds for dividends, however, the OCC may prohibit the payment of any dividends by First Mid Bank if the OCC determines that such payment would constitute an unsafe or unsound practice.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities
	First Mid Bank enters into financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers.  These financial instruments include lines of credit, letters of credit and other commitments to extend credit.  Each of these instruments involves, to varying degrees, elements of credit, interest rate and liquidity risk in excess of the amounts recognized in the consolidated balance sheets.  The Company uses the same credit policies and requires similar collateral in approving lines of credit and commitments and issuing letters of credit as it does in making loans. The exposure to credit losses on financial instruments is represented by the contractual amount of these instruments. However, the Company does not anticipate any losses from these instruments.
	The off-balance sheet financial instruments whose contract amounts represent credit risk at December 31, 2014 and 2013 were as follows (in thousands):
		2014		2013
	Unused commitments and lines of credit:
	Commercial real estate	$	32,927	$	23,770
	Commercial operating	133,884		139,395
	Home equity	23,285		24,071
	Other	47,498		52,251
	Total	$	237,594	$	239,487
	Standby letters of credit	$	5,193	$	4,732
	Commitments to originate credit represent approved commercial, residential real estate and home equity loans that generally are expected to be funded within ninety days.  Lines of credit are agreements by which the Company agrees to provide a borrowing accommodation up to a stated amount as long as there is no violation of any condition established in the loan agreement.  Both commitments to originate credit and lines of credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the lines and some commitments are expected to expire without being drawn upon, the total amounts do not necessarily represent future cash requirements.
	Standby letters of credit are conditional commitments issued by the Company to guarantee the financial performance of customers to third parties.  Standby letters of credit are primarily issued to facilitate trade or support borrowing arrangements and generally expire in one year or less.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending credit facilities to customers.  The maximum amount of credit that would be extended under letters of credit is equal to the total off-balance sheet contract amount of such instrument at December 31, 2014 and 2013. The Company's deferred revenue under standby letters of credit was nominal.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting and Consolidation	Basis of Accounting and Consolidation
	The accompanying consolidated financial statements include the accounts of First Mid-Illinois Bancshares, Inc. (“Company”) and its wholly-owned subsidiaries:  Mid-Illinois Data Services, Inc. (“MIDS”), First Mid-Illinois Bank & Trust, N.A. (“First Mid Bank”) and The Checkley Agency, Inc. doing business as First Mid Insurance Group (“First Mid Insurance”).  All significant intercompany balances and transactions have been eliminated in consolidation.   Certain amounts in the prior year’s consolidated financial statements have been reclassified to conform to the 2014 presentation and there was no impact on net income or stockholders’ equity from these reclassifications.  The Company operates as a single segment entity for financial reporting purposes. The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America. Following is a description of the more significant of these policies.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes.  The Company uses estimates and employs the judgments of management in determining the amount of its allowance for loan losses and income tax accruals and deferrals, in its fair value measurements of investment securities, and in the evaluation of impairment of loans, goodwill, investment securities, and fixed assets. As with any estimate, actual results could differ from these estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses.  In connection with the determination of the allowance for loan losses, management obtains independent appraisals for significant properties.
Fair Value Measurements	Fair Value Measurements
	The fair value of a financial instrument is defined as the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The Company estimates the fair value of a financial instrument using a variety of valuation methods. Where financial instruments are actively traded and have quoted market prices, quoted market prices are used for fair value. When the financial instruments are not actively traded, other observable market inputs, such as quoted prices of securities with similar characteristics, may be used, if available, to determine fair value. When observable market prices do not exist, the Company estimates fair value. The Company’s valuation methods consider factors such as liquidity and concentration concerns. Other factors such as model assumptions, market dislocations, and unexpected correlations can affect estimates of fair value. Imprecision in estimating these factors can impact the amount of revenue or loss recorded.
	At the end of each quarter, the Company assesses the valuation hierarchy for each asset or liability measured. From time to time, assets or liabilities may be transferred within hierarchy levels due to changes in availability of observable market inputs to measure fair value at the measurement date. Transfers into or out of hierarchy levels are based upon the fair value at the beginning of the reporting period. A more detailed description of the fair values measured at each level of the fair value hierarchy can be found in Note 11 – “Disclosures of Fair Values of Financial Instruments.”
Cash and Cash Equivalents and Certificates of Deposit Investments	Cash and Cash Equivalents
	For purposes of reporting cash flows, cash equivalents include non-interest bearing and interest bearing cash and due from banks and federal funds sold. Generally, federal funds are sold for one-day periods.
	Certificates of Deposit Investments
	Certificates of deposit investments have original maturities of six to twelve months and are carried at cost.
Investment Securities	Investment Securities
	The Company classifies its investments in debt and equity securities as either held-to-maturity or available-for-sale in accordance with Statement of Financial Accounting  Standards (SFAS) No. 115, “Accounting for Certain Investments in Debt and Equity Securities,” which was codified into ASC 320. Securities classified as held-to-maturity are recorded at cost or amortized cost. Available-for-sale securities are carried at fair value. Fair value calculations are based on quoted market prices when such prices are available. If quoted market prices are not available, estimates of fair value are computed using a variety of techniques, including extrapolation from the quoted prices of similar instruments or recent trades for thinly traded securities, fundamental analysis, or through obtaining purchase quotes. Due to the subjective nature of the valuation process, it is possible that the actual fair values of these investments could differ from the estimated amounts, thereby affecting the financial position, results of operations and cash flows of the Company. If the estimated value of investments is less than the cost or amortized cost, the Company evaluates whether an event or change in circumstances has occurred that may have a significant adverse effect on the fair value of the investment. If such an event or change has occurred and the Company determines that the impairment is other-than-temporary, a further determination is made as to the portion of impairment that is related to credit loss. The impairment of the investment that is related to the credit loss is expensed in the period in which the event or change occurred. The remainder of the impairment is recorded in other comprehensive income.
Loans	Loans
	Loans are stated at the principal amount outstanding net of unearned discounts, unearned income and the allowance for loan losses.  Unearned income includes deferred loan origination fees reduced by loan origination costs and is amortized to interest income over the life of the related loan using methods that approximate the effective interest rate method. Interest on substantially all loans is credited to income based on the principal amount outstanding.
	The Company’s policy is to discontinue the accrual of interest income on any loan that becomes ninety days past due as to principal or interest or earlier when, in the opinion of management there is reasonable doubt as to the timely collection of principal or interest. Nonaccrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collectability of interest or principal.
	Loans expected to be sold are classified as held for sale in the consolidated financial statements and are recorded at the lower of aggregate cost or market value, taking into consideration future commitments to sell the loans.
Allowance for Loan Losses	Allowance for Loan Losses
	The Company believes the allowance for loan losses is the critical accounting policy that requires the most significant judgments and assumptions used in the preparation of its consolidated financial statements. An estimate of potential losses inherent in the loan portfolio is determined and an allowance for those losses is established by considering factors including historical loss rates, expected cash flows and estimated collateral values. In assessing these factors, the Company use organizational history and experience with credit decisions and related outcomes. The allowance for loan losses represents the best estimate of losses inherent in the existing loan portfolio. The allowance for loan losses is increased by the provision for loan losses charged to expense and reduced by loans charged off, net of recoveries. The Company evaluates the allowance for loan losses quarterly. If the underlying assumptions later prove to be inaccurate based on subsequent loss evaluations, the allowance for loan losses is adjusted.
	The Company estimates the appropriate level of allowance for loan losses by separately evaluating impaired and nonimpaired loans. A specific allowance is assigned to an impaired loan when expected cash flows or collateral do not justify the carrying amount of the loan. The methodology used to assign an allowance to a nonimpaired loan is more subjective. Generally, the allowance assigned to nonimpaired loans is determined by applying historical loss rates to existing loans with similar risk characteristics, adjusted for qualitative factors including the volume and severity of identified classified loans, changes in economic conditions, changes in credit policies or underwriting standards, and changes in the level of credit risk associated with specific industries and markets. Because the economic and business climate in any given industry or market, and its impact on any given borrower, can change rapidly, the risk profile of the loan portfolio is continually assessed and adjusted when appropriate. Notwithstanding these procedures, there still exists the possibility that the assessment could prove to be significantly incorrect and that an immediate adjustment to the allowance for loan losses would be required.
Premises and Equipment	Premises and Equipment
	Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is charged to expense and determined principally by the straight-line method over the estimated useful lives of the assets. The estimated useful lives for each major depreciable classification of premises and equipment are as follows:
Goodwill and Intangible Assets	Goodwill and Intangible Assets
	The Company has goodwill from business combinations, identifiable intangible assets assigned to core deposit relationships and customer lists acquired, and intangible assets arising from the rights to service mortgage loans for others.
	Identifiable intangible assets generally arise from branches acquired that the Company accounted for as purchases.  Such assets consist of the excess of the purchase price over the fair value of net assets acquired, with specific amounts assigned to core deposit relationships and customer lists primarily related to insurance agency.  Intangible assets are amortized by the straight-line method over various periods up to fifteen years.  Management reviews intangible assets for possible impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
	In accordance with the provisions of SFAS No. 142, “Goodwill and Other Intangible Assets,” codified into ASC 350, the Company performed testing of goodwill for impairment as of September 30, 2014 and determined that, as of that date, goodwill was not impaired.  Management also concluded that the remaining amounts and amortization periods were appropriate for all intangible assets.
Other Real Estate Owned	Other Real Estate Owned
	Other real estate owned acquired through loan foreclosure is initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. The adjustment at the time of foreclosure is recorded through the allowance for loan losses. Due to the subjective nature of establishing the fair value when the asset is acquired, the actual fair value of the other real estate owned or foreclosed asset could differ from the original estimate. If it is determined that fair value temporarily declines subsequent to foreclosure, a valuation allowance is recorded through noninterest expense. Operating costs associated with the assets after acquisition are also recorded as noninterest expense. Gains and losses on the disposition of other real estate owned and foreclosed assets are netted and posted to other noninterest expense.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock
	Federal Home Loan Bank stock is a required investment for institutions that are members of the Federal Home Loan Bank system.  The required investment in the common stock is based on a predetermined formula.
Income Taxes	Income Taxes
	The Company and its subsidiaries file consolidated federal and state income tax returns with each organization computing its taxes on a separate company basis.  Amounts provided for income tax expense are based on income reported for financial statement purposes rather than amounts currently payable under tax laws.
	Deferred tax assets and liabilities are recognized for future tax consequences attributable to the temporary differences existing between the financial statement carrying amounts of assets and liabilities and their respective tax basis, as well as operating loss and tax credit carry forwards.  To the extent that current available evidence about the future raises doubt about the realization of a deferred tax asset, a valuation allowance is established.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized as an increase or decrease in income tax expense in the period in which such change is enacted.
	Additionally, the Company reviews its uncertain tax positions annually under FASB Interpretation No. 48 (FIN No. 48), “Accounting for Uncertainty in Income Taxes,” codified within ASC 740. An uncertain tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount actually recognized is the largest amount of tax benefit that is greater than 50% likely to be recognized on examination. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded. A significant amount of judgment is applied to determine both whether the tax position meets the "more likely than not" test as well as to determine the largest amount of tax benefit that is greater than 50% likely to be recognized. Differences between the position taken by management and that of taxing authorities could result in a reduction of a tax benefit or increase to tax liability, which could adversely affect future income tax expense.
Trust Department Assets	Trust Department Assets
	Assets held in fiduciary or agency capacities are not included in the consolidated balance sheets since such items are not assets of the Company or its subsidiaries.  Fees from trust activities are recorded on a cash basis over the period in which the service is provided.  Fees are a function of the market value of assets managed and administered, the volume of transactions, and fees for other services rendered, as set forth in the underlying client agreement with the Trust & Wealth Management Division of First Mid Bank.  This revenue recognition involves the use of estimates and assumptions, including components that are calculated based on asset valuations and transaction volumes.  Any out of pocket expenses or services not typically covered by the fee schedule for trust activities are charged directly to the trust account on a gross basis as trust revenue is incurred.
Convertible Preferred Stock	Convertible Preferred Stock
	Series B Convertible Preferred Stock.  During 2009, the Company sold to certain accredited investors including directors, executive officers, and certain major customers and holders of the Company’s common stock, $24,635,000, in the aggregate, of a newly authorized series of its preferred stock designated as Series B 9% Non-Cumulative Perpetual Convertible Preferred Stock (the “Series B Preferred Stock”). The Series B Preferred Stock had an issue price of $5,000 per share and no par value per share.  The Series B Preferred Stock was issued in a private placement exempt from registration pursuant to Regulation D of the Securities Act of 1933, as amended.
	The Series B Preferred Stock pays non-cumulative dividends semiannually in arrears, when, as and if authorized by the Board of Directors of the Company, at a rate of 9% per year.  Holders of the Series B Preferred Stock will have no voting rights, except with respect to certain fundamental changes in the terms of the Series B Preferred Stock and certain other matters.  In addition, if dividends on the Series B Preferred Stock are not paid in full for four dividend periods, whether consecutive or not, the holders of the Series B Preferred Stock, acting as a class with any other of the Company’s securities having similar voting rights, will have the right to elect two directors to the Company’s Board of Directors.  The terms of office of these directors will end when the Company has paid or set aside for payment full semi-annual dividends for four consecutive dividend periods.
	Each share of the Series B Preferred Stock may be converted at any time at the option of the holder into shares of the Company’s common stock.  The number of shares of common stock into which each share of the Series B Preferred Stock is convertible is the $5,000 liquidation preference per share divided by the Conversion Price initially set at $21.94.  The Conversion Price is subject to adjustment from time to time pursuant to the terms of the Certificate of Designation (the “Series B Certificate of Designation”).   If at the time of conversion, there are any authorized, declared and unpaid dividends with respect to a converted share of Series B Preferred Stock, the holder will receive cash in lieu of the dividends, and a holder will receive cash in lieu of fractional shares of common stock following conversion.
	After November 16, 2014, the Company may, at its option but subject to the Company’s receipt of any required prior approvals from the Board of Governors of the Federal Reserve System or any other regulatory authority, redeem the Series B Preferred Stock.  Any redemption will be in exchange for cash in the amount of $5,000 per share, plus any authorized, declared and unpaid dividends, without accumulation of any undeclared dividends.
	The Company also has the right at any time on or after November 16, 2014 to require the conversion of all (but not less than all) of the Series B Preferred Stock into shares of common stock if, on the date notice of mandatory conversion is given to holders, the book value of the Company’s common stock equals or exceeds 115% of the book value of the Company’s common stock at September 30, 2008. “Book value of the Company’s common stock” at any date means the result of dividing the Company’s total common stockholders’ equity at that date, determined in accordance with U.S. generally accepted accounting principles, by the number of shares of common stock then outstanding, net of any shares held in the treasury.  The book value of the Company’s common stock at September 30, 2008 was $13.03, and 115% of this amount is approximately $14.98. The book value of the Company’s common stock at December 31, 2014 was $19.55.
	Pursuant to Section 3(j) of the Series B Certification of Designation, the conversion price for the Series B Preferred Stock, which was initially set at $21.94, was required to be adjusted if, among other things, the initial conversion price of any subsequently issued series of preferred stock was lower than the then current conversion price of the Series B Preferred Stock.  As a result of the Series C Preferred Stock (see below) having an initial conversion price of less than $21.94, the conversion price of the Series B Preferred Stock was adjusted pursuant to the terms of the Series B Certificate of Designation based on the amount of Series C Preferred Stock sold on February 11, 2011, March 2, 2011, May 13, 2011 and June 28, 2012.  The current conversion price of the Series B Preferred Stock, certified by the Company’s accountant pursuant to Section 3(j) of the Series B Certificate of Designation, is $21.62.
	On September 23, 2014, the Board of Directors of the Company approved the mandatory conversion of all of the Company's issued and outstanding 4,926 shares of Series B Preferred Stock into shares of the Company’s common stock. On September 24, 2014, notices were sent to the shareholders of the Series B Preferred Stock regarding the mandatory conversion. On November 17, 2014, the Company completed the mandatory conversion. The conversion ratio for each share of the Series B Preferred Stock was computed by dividing $5,000 (the issuance price per share of the Series B Preferred Stock) by $21.62. (the then current conversion price). The conversion ratio, therefore, was 231.267 shares of the Company's common stock for each share of Series B Preferred Stock. This resulted in the issuance of approximately 1,139,195 shares of common stock in the aggregate. As a result of the conversion, dividends ceased to accrue on the Series B Preferred Stock and certificates for shares of Series B Preferred Stock only represent the right to receive the appropriate number of shares of common stock, together with net accrued but unpaid dividends, and cash in lieu of fractional share interests.
	Series C Convertible Preferred Stock.  On February 11, 2011, the Company accepted from certain accredited investors, including directors, executive officers, and certain major customers and holders of the Company’s common stock (collectively, the “Investors”), subscriptions for the purchase of $27,500,000, in the aggregate, of a newly authorized series of preferred stock designated as Series C 8% Non-Cumulative Perpetual Convertible Preferred Stock (the “Series C Preferred Stock”). As of February 11, 2011, $11,010,000 of the Series C Preferred Stock had been issued and sold by the Company to certain Investors.  On March 2, 2011, three investors subsequently completed the required bank regulatory process and an additional $2,750,000 of Series C Preferred Stock was issued and sold by the Company to these investors. On May 13, 2011, four additional investors received the required bank regulatory approval and an additional $5,490,000 of Series C Preferred Stock was issued and sold by the Company to these investors. On June 28, 2012, the final $8,250,000 of the Company’s Series C Preferred Stock was issued and sold by the Company to Investors following their receipt of the required bank regulatory approval, for a total of $27,500,000 of outstanding Series C Preferred Stock. All of the Series C Preferred Stock subscribed for by investors has been issued.
	The Series C Preferred Stock has an issue price of $5,000 per share and no par value per share.  The Series C Preferred Stock was issued in a private placement exempt from registration pursuant to Regulation D of the Securities Act of 1933, as amended.
	The Series C Preferred Stock pays non-cumulative dividends semiannually in arrears, when, as and if authorized by the Board of Directors of the Company, at a rate of 8% per year.  Holders of the Series C Preferred Stock will have no voting rights, except with respect to certain fundamental changes in the terms of the Series C Preferred Stock and certain other matters.  In addition, if dividends on the Series C Preferred Stock are not paid in full for four dividend periods, whether consecutive or not, the holders of the Series C Preferred Stock, acting as a class with any other of the Company’s securities having similar voting rights, including the Company’s Series B Preferred Stock, will have the right to elect two directors to the Company’s Board of Directors.  The terms of office of these directors will end when the Company has paid or set aside for payment full semi-annual dividends for four consecutive dividend periods.
	Each share of the Series C Preferred Stock may be converted at any time at the option of the holder into shares of the Company’s common stock.  The number of shares of common stock into which each share of the Series C Preferred Stock is convertible is the $5,000 liquidation preference per share divided by the Conversion Price of $20.29.  The Conversion Price is subject to adjustment from time to time pursuant to the terms of the Series C Certificate of Designation.  If at the time of conversion, there are any authorized, declared and unpaid dividends with respect to a converted share of Series C Preferred Stock, the holder will receive cash in lieu of the dividends, and a holder will receive cash in lieu of fractional shares of common stock following conversion.
	After May 13, 2016 the Company may, at its option but subject to the Company’s receipt of any required prior approvals from the Board of Governors of the Federal Reserve System or any other regulatory authority, redeem the Series C Preferred Stock.  Any redemption will be in exchange for cash in the amount of $5,000 per share, plus any authorized, declared and unpaid dividends, without accumulation of any undeclared dividends.
	The Company also has the right at any time after May 13, 2016 to require the conversion of all (but not less than all) of the Series C Preferred Stock into shares of common stock if, on the date notice of mandatory conversion is given to holders, (a) the tangible book value per share of the Company’s common stock equals or exceeds 115% of the tangible book value per share of the Company’s common stock at December 31, 2010, and (b) the NASDAQ Bank Index (denoted by CBNK:IND) equals or exceeds 115% of the NASDAQ Bank Index at December 31, 2010.  “Tangible book value per share of our common stock” at any date means the result of dividing the Company’s total common stockholders equity at that date, less the amount of goodwill and intangible assets, determined in accordance with U.S. generally accepted accounting principles, by the number of shares of common stock then outstanding, net of any shares held in the treasury. The tangible book value of the Company’s common stock at December 31, 2010 was $9.38, and 115% of this amount is approximately $10.79. The NASDAQ Bank Index value at December 31, 2010 was 1,847.35 and 115% of this amount is approximately 2,124.45. The tangible book value of the Company’s common stock at December 31, 2014 was $15.63 and the NASDAQ Bank Index value at December 31, 2014 was 2,675.88.
Treasury Stock	Treasury Stock
Stock Incentive Awards	Stock Incentive Awards
	At the Annual Meeting of Stockholders held May 23, 2007, the stockholders approved the First Mid-Illinois Bancshares, Inc. 2007 Stock Incentive Plan (“SI Plan”).  The SI Plan was implemented to succeed the Company’s 1997 Stock Incentive Plan, which had a ten-year term that expired October 21, 2007. The SI Plan is intended to provide a means whereby directors, employees, consultants and advisors of the Company and its subsidiaries may sustain a sense of proprietorship and personal involvement in the continued development and financial success of the Company and its subsidiaries, thereby advancing the interests of the Company and its stockholders.  Accordingly, directors and selected employees, consultants and advisors may be provided the opportunity to acquire shares of common stock of the Company on the terms and conditions established in the SI Plan. On September 27, 2011, the Board of Directors passed a resolution relating to the SI Plan whereby they authorized and approved the Executive Long-Term Incentive Plan (“LTIP”). The LTIP was implemented to provide methodology for granting Stock Awards and Stock Unit Awards to select senior executives of the Company or any Subsidiary.
	A maximum of 300,000 shares of common stock may be issued under the SI Plan.  Prior to December 31, 2008, the Company had awarded 59,500 shares as stock options under the SI plan.  There have been no stock options awarded since 2008. The Company awarded 19,377 shares, 14,054 shares and 15,162 shares during 2014, 2013 and 2012, respectively, as 50% Stock Awards and 50% Stock Unit Awards under the SI plan.

	During the third quarter of 2014, management evaluated its available-for-sale portfolio and transferred obligations of U.S. government corporations & agencies securities with a fair value of $53.6 million from available-for-sale to held-to-maturity to reduce price volatility. Management determined it has both the intent and ability to hold these securities to maturity. Transfers of investment securities into the held-to-maturity category from available-for-sale are made at fair value on the date of transfer. There were no gains or losses recognized as a result of this transfer. The related $1.4 million of unrealized holding loss that was included in the transfer is retained in the carrying value of the held-to-maturity securities and in other comprehensive income net of deferred taxes. These amounts are being amortized into net interest income over the remaining life of the related securities as a yield adjustment, resulting in no impact on future net income.
	Trust preferred securities at December 31, 2014, is one trust preferred pooled security issued by First Tennessee Financial (“FTN”). The unrealized loss of this security, which has a maturity of twenty-three years, is primarily due to its long-term nature, a lack of demand or inactive market for the security, and concerns regarding the underlying financial institutions that have issued the trust preferred security. See the heading “Trust Preferred Securities” below for further information regarding this security.
