Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	1. SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation We have five separate business trusts that were formed to issue trust preferred securities. Subordinated debentures were issued to the trusts in return for the proceeds raised from the issuance of the trust preferred securities. The trusts are not consolidated, but instead we report the subordinated debentures issued to the trusts as a liability. Earnings Per Share Approximately 150,000 unvested restricted shares were included in determining both basic and diluted earnings per share for the three months ended March 31, 2016. In addition, stock options for approximately 118,000 shares of common stock were included in determining diluted earnings per share for the three months ended March 31, 2016. Stock options for approximately 10,000 shares of common stock were antidilutive and not included in determining diluted earnings per share for the three months ended March 31, 2016. Approximately 101,000 unvested restricted shares were included in determining both basic and diluted earnings per share for the three months ended March 31, 2015. In addition, stock options for approximately 121,000 shares of common stock were included in determining diluted earnings per share for the three months ended March 31, 2015. Stock options for approximately 118,000 shares of common stock were antidilutive and not included in determining diluted earnings per share for the three months ended March 31, 2015. Securities Interest income includes amortization of purchase premiums and accretion of discounts. Premiums and discounts on securities are amortized or accreted on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Declines in the fair value of debt securities below their amortized cost that are other than temporary (“OTTI”) are reflected in earnings or other comprehensive income, as appropriate. For those debt securities whose fair value is less than their amortized cost, we consider our intent to sell the security, whether it is more likely than not that we will be required to sell the security before recovery and whether we expect to recover the entire amortized cost of the security based on our assessment of the issuer’s financial condition. In analyzing an issuer’s financial condition, we consider whether the securities are issued by the federal government or its agencies, and whether downgrades by bond rating agencies have occurred. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement, and 2) OTTI related to other factors, such as liquidity conditions in the market or changes in market interest rates, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost. Loans Interest income on commercial loans and mortgage loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Consumer and credit card loans are typically charged off no later than when they are 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal and interest is considered doubtful. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Loans Held for Sale Mortgage loans held for sale are generally sold with servicing rights retained. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold, which is reduced by the cost allocated to the servicing right. We generally lock in the sale price to the purchaser of the loan at the same time we make a rate commitment to the borrower. These mortgage banking activities are not designated as hedges and are carried at fair value. The net gain or loss on mortgage banking derivatives is included in the gain on sale of loans. Mortgage loans serviced for others totaled approximately $600 million as of March 31, 2016. Mortgage Banking Activities Servicing fee income is recorded for fees earned for serving mortgage loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Amortization of mortgage loan servicing rights is netted against mortgage loan servicing income and recorded in mortgage banking activities in the income statement. Troubled Debt Restructurings In accordance with current accounting guidance, loans modified as troubled debt restructurings are, by definition, considered to be impaired loans. Impairment for these loans is measured on a loan-by-loan basis similar to other impaired loans as described below under “Allowance for Loan Losses.” Certain loans modified as troubled debt restructurings may have been previously measured for impairment under a general allowance methodology (i.e., pooling), thus at the time the loan is modified as a troubled debt restructuring the allowance will be impacted by the difference between the results of these two measurement methodologies. Loans modified as troubled debt restructurings that subsequently default are factored into the determination of the allowance in the same manner as other defaulted loans. Allowance for Loan Losses A loan is considered to be impaired when, based on current information and events, it is probable we will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of delay, the reasons for delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of collateral if the loan is collateral dependent. Derivatives Changes in the fair value of derivatives that are designated, for accounting purposes, as a hedge of the variability of cash flows to be received on various loans and are effective are reported in other comprehensive income. They are later reclassified into earnings in the same periods during which the hedged transaction affects earnings and are included in the line item in which the hedged cash flows are recorded. If hedge accounting does not apply, changes in the fair value of derivatives are recognized immediately in current earnings as interest income or expense. If designated as a hedge, we formally document the relationship between derivatives as hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions. This documentation includes linking cash flow hedges to specific assets and liabilities on the balance sheet. If designated as a hedge, we also formally assess, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in cash flows of the hedged items. Ineffective hedge gains and losses are recognized immediately in current earnings as noninterest income or expense. We discontinue hedge accounting when we determine the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative is settled or terminates, or treatment of the derivative as a hedge is no longer appropriate or intended. Goodwill and Core Deposit Intangible The core deposit intangible that arose from the Firstbank Corporation acquisition was initially measured at fair value and is being amortized into noninterest expense over a ten-year period using the sum-of-the-years-digits methodology.

Consideration is given to the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability we have to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. For those debt securities whose fair value is less than their amortized cost basis, we also consider our intent to sell the security, whether it is more likely than not that we will be required to sell the security before recovery and if we do not expect to recover the entire amortized cost basis of the security. In analyzing an issuer’s financial condition, we may consider whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred and the results of reviews of the issuer’s financial condition. At March 31, 2016, 136 debt securities with fair values totaling $88.4 million have unrealized losses aggregating $0.8 million. After we considered whether the securities were issued by the federal government or its agencies and whether downgrades by bond rating agencies had occurred, we determined that the unrealized losses were due to changing interest rate environments. As we do not intend to sell our debt securities before recovery of their cost basis and we believe it is more likely than not that we will not be required to sell our debt securities before recovery of the cost basis, no unrealized losses are deemed to be other-than-temporary. The amortized cost and fair value of debt securities at March 31, 2016, by maturity, are shown in the following table. The contractual maturity is utilized for U.S. Government agency debt obligations and municipal bonds. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date, primarily mortgage-backed securities, are shown separately. Weighted average yields are also reflected, with yields for municipal securities shown at their tax equivalent yield.

Securities issued by all other states and their political subdivisions had a combined amortized cost of $22.9 million and $24.0 million at March 31, 2016 and December 31, 2015, respectively, with estimated market values of $23.2 million and $24.1 million, respectively. Total securities of any other specific issuer, other than the U.S. Government and its agencies and the State of Michigan and all its political subdivisions, did not exceed 10% of shareholders’ equity. The carrying value of U.S. Government agency debt obligations and mortgage-backed securities that are pledged to secure repurchase agreements was $162 million and $155 million at March 31, 2016 and December 31, 2015, respectively. Investments in Federal Home Loan Bank stock are restricted and may only be resold or redeemed by the issuer.

Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	3. LOANS AND ALLOWANCE FOR LOAN LOSSES Loans originated for investment are stated at their principal amount outstanding adjusted for partial charge-offs, the allowance, and net deferred loan fees and costs. Interest income on loans is accrued over the term of the loans primarily using the simple interest method based on the principal balance outstanding. Interest is not accrued on loans where collectability is uncertain. Accrued interest is presented separately in the consolidated balance sheet. Loan origination fees and certain direct costs incurred to extend credit are deferred and amortized over the term of the loan or loan commitment period as an adjustment to the related loan yield. Acquired loans are those purchased in the Firstbank merger. These loans were recorded at estimated fair value at the merger date with no carryover of the related allowance. The acquired loans were segregated between those considered to be performing (“acquired non-impaired loans”) and those with evidence of credit deterioration (“acquired impaired loans”). Acquired loans are considered impaired if there is evidence of credit deterioration and if it is probable, at acquisition, all contractually required payments will not be collected. Acquired loans restructured after acquisition are not considered or reported as troubled debt restructurings if the loans evidenced credit deterioration as of the merger date and are accounted for in pools. The fair value estimates for acquired loans are based on expected prepayments and the amount and timing of discounted expected principal, interest and other cash flows. Credit discounts representing the principal losses expected over the life of the loan are also a component of the initial fair value. In determining the merger date fair value of acquired impaired loans, and in subsequent accounting, we have generally aggregated acquired commercial and consumer loans into pools of loans with common risk characteristics. The difference between the fair value of an acquired non-impaired loan and contractual amounts due at the merger date is accreted into income over the estimated life of the loan. Contractually required payments represent the total undiscounted amount of all uncollected principal and interest payments. Acquired non-impaired loans are placed on nonaccrual status and reported as nonperforming or past due using the same criteria applied to the originated loan portfolio. The excess of an acquired impaired loan’s undiscounted contractually required payments over the amount of its undiscounted cash flows expected to be collected is referred to as the non-accretable difference. The non-accretable difference, which is neither accreted into income nor recorded on the consolidated balance sheet, reflects estimated future credit losses and uncollectible contractual interest expected to be incurred over the life of the acquired impaired loan. The excess cash flows expected to be collected over the carrying amount of the acquired loan is referred to as the accretable yield. This amount is accreted into interest income over the remaining life of the acquired loans or pools using the level yield method. The accretable yield is affected by changes in interest rate indices for variable rate loans, changes in prepayment speed assumptions and changes in expected principal and interest payments over the estimated lives of the acquired impaired loans. We evaluate quarterly the remaining contractual required payments receivable and estimate cash flows expected to be collected over the lives of the impaired loans. Contractually required payments receivable may increase or decrease for a variety of reasons, for example, when the contractual terms of the loan agreement are modified, when interest rates on variable rate loans change, or when principal and/or interest payments are received. Cash flows expected to be collected on acquired impaired loans are estimated by incorporating several key assumptions similar to the initial estimate of fair value. These key assumptions include probability of default, loss given default, and the amount of actual prepayments after the merger date. Prepayments affect the estimated lives of loans and could change the amount of interest income, and possibly principal, expected to be collected. In re-forecasting future estimated cash flows, credit loss expectations are adjusted as necessary. The adjustments are based, in part, on actual loss severities recognized for each loan type, as well as changes in the probability of default. For periods in which estimated cash flows are not re-forecasted, the prior reporting period’s estimated cash flows are adjusted to reflect the actual cash received and credit events that transpired during the current reporting period. Increases in expected cash flows of acquired impaired loans subsequent to the merger date are recognized prospectively through adjustments of the yield on the loans or pools over their remaining lives, while decreases in expected cash flows are recognized as impairment through a provision for loan losses and an increase in the allowance. Our total loans at March 31, 2016 were $2.30 billion compared to $2.28 billion at December 31, 2015, an increase of $17.9 million, or 0.8%. The components of our loan portfolio disaggregated by class of loan within the loan portfolio segments at March 31, 2016 and December 31, 2015, and the percentage change in loans from the end of 2015 to the end of the first quarter of 2016, are as follows: Percent March 31, 2016 December 31, 2015 Increase Balance % Balance % (Decrease) Originated loans Commercial: Commercial and industrial $ 613,570,000 36.4 % $ 577,872,000 35.7 % 6.2 % Vacant land, land development, and residential construction 28,451,000 1.7 30,138,000 1.9 (5.6 ) Real estate – owner occupied 334,948,000 19.8 330,798,000 20.5 1.3 Real estate – non-owner occupied 549,226,000 32.5 520,754,000 32.2 5.5 Real estate – multi-family and residential rental 36,582,000 2.2 33,954,000 2.1 7.7 Total commercial 1,562,777,000 92.6 1,493,516,000 92.4 4.6 Retail: Home equity and other 68,342,000 4.1 67,816,000 4.2 0.8 1-4 family mortgages 56,357,000 3.3 55,255,000 3.4 2.0 Total retail 124,699,000 7.4 123,071,000 7.6 1.3 Total originated loans $ 1,687,476,000 100.0 % $ 1,616,587,000 100.0 % 4.4 % Percent March 31, 2016 December 31, 2015 Increase Balance % Balance % (Decrease) Acquired loans Commercial: Commercial and industrial $ 101,042,000 16.6 % $ 118,431,000 17.9 % (14.7% ) Vacant land, land development, and residential construction 11,179,000 1.9 14,982,000 2.3 (25.4 ) Real estate – owner occupied 106,714,000 17.5 115,121,000 17.4 (7.3 ) Real estate – non-owner occupied 116,787,000 19.2 123,597,000 18.7 (5.5 ) Real estate – multi-family and residential rental 75,951,000 12.5 81,049,000 12.3 (6.3 ) Total commercial 411,673,000 67.7 453,180,000 68.6 (9.2 ) Retail: Home equity and other 67,341,000 11.1 72,830,000 11.0 (7.5 ) 1-4 family mortgages 129,178,000 21.2 135,130,000 20.4 (4.4 ) Total retail 196,519,000 32.3 207,960,000 31.4 (5.5 ) Total acquired loans $ 608,192,000 100.0 % $ 661,140,000 100.0 % (8.0% ) Percent March 31, 2016 December 31, 2015 Increase Balance % Balance % (Decrease) Total loans Commercial: Commercial and industrial $ 714,612,000 31.1 % $ 696,303,000 30.6 % 2.6 % Vacant land, land development, and residential construction 39,630,000 1.7 45,120,000 2.0 (12.2 ) Real estate – owner occupied 441,662,000 19.3 445,919,000 19.6 (1.0 ) Real estate – non-owner occupied 666,013,000 29.0 644,351,000 28.3 3.4 Real estate – multi-family and residential rental 112,533,000 4.9 115,003,000 5.0 (2.1 ) Total commercial 1,974,450,000 86.0 1,946,696,000 85.5 1.4 Retail: Home equity and other 135,683,000 5.9 140,646,000 6.2 (3.5 ) 1-4 family mortgages 185,535,000 8.1 190,385,000 8.3 (2.5 ) Total retail 321,218,000 14.0 331,031,000 14.5 (3.0 ) Total loans $ 2,295,668,000 100.0 % $ 2,277,727,000 100.0 % 0.8 % The total contractually required payments due on and carrying value of acquired impaired loans were $21.3 million and $10.1 million, respectively, as of March 31, 2016.

Excellent credit rating that contain very little, if any, risk of loss. Grade 2. Strong sources of repayment and have low repayment risk. Grade 3. Good sources of repayment and have limited repayment risk. Grade 4. Adequate sources of repayment and acceptable repayment risk; however, characteristics are present that render the credit more vulnerable to a negative event. Grade 5. Marginally acceptable sources of repayment and exhibit defined weaknesses and negative characteristics. Grade 6. Well defined weaknesses which may include negative current cash flow, high leverage, or operating losses. Generally, if the credit does not stabilize or if further deterioration is observed in the near term, the loan will likely be downgraded and placed on the Watch List (i.e., list of lending relationships that receive increased scrutiny and review by the Board of Directors and senior management). Grade 7. Defined weaknesses or negative trends that merit close monitoring through Watch List status. Grade 8. Inadequately protected by current sound net worth, paying capacity of the obligor, or pledged collateral, resulting in a distinct possibility of loss requiring close monitoring through Watch List status. Grade 9. Vital weaknesses exist where collection of principal is highly questionable. Grade 10. Considered uncollectable and of such little value that continuance as an asset is not warranted. The primary risk elements with respect to commercial loans are the financial condition of the borrower, the sufficiency of collateral, and timeliness of scheduled payments. We have a policy of requesting and reviewing periodic financial statements from commercial loan customers and employ a disciplined and formalized review of the existence of collateral and its value. The primary risk element with respect to each residential real estate loan and consumer loan is the timeliness of scheduled payments. We have a reporting system that monitors past due loans and have adopted policies to pursue creditor’s rights in order to preserve our collateral position.

Disclosure Text Block Supplement [Abstract]
Commitments Contingencies and Guarantees [Text Block]	8. COMMITMENTS AND OFF-BALANCE SHEET RISK Our bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Loan commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Standby letters of credit are conditional commitments issued by our bank to guarantee the performance of a customer to a third party. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized, if any, in the balance sheet. Our bank’s maximum exposure to loan loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. Our bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Collateral, such as accounts receivable, securities, inventory, and property and equipment, is generally obtained based on our credit assessment of the borrower. If required, estimated loss exposure resulting from these instruments is expensed and is generally recorded as a liability. There was no reserve or liability balance for these instruments as of March 31, 2016 and December 31, 2015. A summary of the contractual amounts of our financial instruments with off-balance sheet risk at March 31, 2016 and December 31, 2015 follows: March 31, December 31, 2016 2015 Commercial unused lines of credit $ 501,735,000 $ 522,658,000 Unused lines of credit secured by 1 – 4 family residential properties 62,364,000 61,905,000 Credit card unused lines of credit 16,874,000 15,612,000 Other consumer unused lines of credit 6,497,000 8,583,000 Commitments to make loans 218,392,000 178,034,000 Standby letters of credit 33,567,000 34,946,000 $ 839,429,000 $ 821,738,000 Certain of our commercial loan customers have entered into interest rate swap agreements directly with our correspondent banks. To assist our commercial loan customers in these transactions, and to encourage our correspondent banks to enter into the interest rate swap transactions with minimal credit underwriting analyses on their part, we have entered into risk participation agreements with the correspondent banks whereby we agree to make payments to the correspondent banks owed by our commercial loan customers under the interest rate swap agreement in the event that our commercial loan customers do not make the payments. We are not a party to the interest rate swap agreements under these arrangements. As of March 31, 2016, the total notional amount of the underlying interest rate swap agreements was $14.5 million, with a net fair value from our commercial loan customers’ perspective of negative $2.5 million. These risk participation agreements are considered financial guarantees in accordance with applicable accounting guidance and are therefore recorded as liabilities at fair value, generally equal to the fees collected at the time of their execution. These liabilities are accreted into income during the term of the interest rate swap agreements, generally ranging from four to fifteen years.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	9. HEDGING ACTIVITIES Our interest rate risk policy includes guidelines for measuring and monitoring interest rate risk. Within these guidelines, parameters have been established for maximum fluctuations in net interest income. Possible fluctuations are measured and monitored using net interest income simulation. Our policy provides for the use of certain derivative instruments and hedging activities to aid in managing interest rate risk to within the policy parameters. In February 2012, we entered into an interest rate swap agreement with a correspondent bank to hedge the floating rate on our subordinated debentures, which became effective in January 2013 and matures in January 2018. Our $32.0 million of subordinated debentures have a rate equal to the 90-Day Libor Rate plus a fixed spread of 218 basis points, and are subject to repricing quarterly. The interest rate swap agreement provides for us to pay our correspondent bank a fixed rate, while our correspondent bank will pay us the 90-Day Libor Rate on a $32.0 million notional amount. The quarterly re-set dates for the floating rate on the interest rate swap agreement are the same as the re-set dates for the floating rate on the subordinated debentures. The interest rate swap agreement does qualify for hedge accounting; therefore, monthly fluctuations in the present value of the interest rate swap agreement, net of tax effect, are recorded to other comprehensive income. As of March 31, 2016 and December 31, 2015, the fair value of the interest rate swap agreement was recorded as a liability in the amount of $0.3 million. Effective January 26, 2016, the notional amount of the interest rate swap agreement was reduced from $32.0 million down to $21.0 million, reflecting the $11.0 million repurchase of the associated trust preferred securities on that date. We reclassified out of accumulated other comprehensive income and recorded interest expense of approximately $0.2 million in January 2016 as part of the transaction, reflecting the market value (i.e., present value of expected future cash flows) of the interest rate swap on that date of the $11.0 million portion.

(2) It is not practical to determine the fair value of FHLBI stock due to transferability restrictions. Carrying amount is the estimated fair value for cash and cash equivalents, accrued interest receivable and payable, bank owned life insurance, noninterest checking deposits, securities sold under agreements to repurchase, and variable rate loans and deposits that reprice frequently and fully. Security fair values are based on market prices or dealer quotes, and if no such information is available, on the rate and term of the security and information about the issuer. For fixed rate loans and deposits and for variable rate loans and deposits with infrequent repricing or repricing limits, fair value is based on discounted cash flows using current market rates applied to the estimated life and credit risk. Fair value of subordinated debentures and FHLBI advances is based on current rates for similar financing. Fair value of the interest rate swap is determined primarily utilizing market-consensus forecasted yield curves. Fair value of off-balance sheet items is estimated to be nominal.

Fair Value, Measurement Inputs, Disclosure [Text Block]	Table Of Contents 11. FAIR VALUES Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability, or in the absence of a principal market, the most advantageous market for the asset or liability. The price of the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact. We are required to use valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from independent sources, or unobservable, meaning those that reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. In that regard, we utilize a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that we have the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be derived from or corroborated by observable market data by correlation or other means. Level 3: Significant unobservable inputs that reflect our own conclusions about the assumptions that market participants would use in pricing an asset or liability. The following is a description of our valuation methodologies used to measure and disclose the fair values of our financial assets and liabilities that are recorded at fair value on a recurring or nonrecurring basis: Securities available for sale.

Regulatory Capital Requirements under Banking Regulations [Text Block]	12. REGULATORY MATTERS We are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weightings, and other factors, and the regulators can lower classifications in certain cases. Failure to meet various capital requirements can initiate regulatory action that could have a direct material effect on our financial statements. The prompt corrective action regulations provide five classifications, including well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If an institution is not well capitalized, regulatory approval is required to accept brokered deposits. Subject to limited exceptions, no institution may make a capital distribution if, after making the distribution, it would be undercapitalized. If an institution is undercapitalized, it is subject to close monitoring by its principal federal regulator, its asset growth and expansion are restricted, and plans for capital restoration are required. In addition, further specific types of restrictions may be imposed on the institution at the discretion of the federal regulator. At March 31, 2016 and December 31, 2015, our bank was in the well capitalized category under the regulatory framework for prompt corrective action. There are no conditions or events since March 31, 2016 that we believe have changed our bank’s categorization. Our actual capital levels (dollars in thousands) and the minimum levels required to be categorized as adequately and well capitalized were: Minimum Required to be Well Minimum Required Capitalized Under for Capital Prompt Corrective Actual Adequacy Purposes Action Regulations Amount Ratio Amount Ratio Amount Ratio March 31, 2016 Total capital (to risk Consolidated $ 340,557 13.1 % $ 207,722 8.0 % $ NA NA Bank 340,668 13.1 207,495 8.0 259,369 10.0 % Tier 1 capital (to risk Consolidated 324,296 12.5 155,792 6.0 NA NA Bank 324,406 12.5 155,622 6.0 207,495 8.0 Common equity tier 1 Consolidated 282,044 10.9 116,844 4.5 NA NA Bank 324,406 12.5 116,716 4.5 168,590 6.5 Tier 1 capital (to average assets) Consolidated 324,296 11.4 113,529 4.0 NA NA Bank 324,406 11.4 113,448 4.0 141,810 5.0 Minimum Required to be Well Minimum Required Capitalized Under for Capital Prompt Corrective Actual Adequacy Purposes Action Regulations Amount Ratio Amount Ratio Amount Ratio December 31, 2015 Total capital (to risk weighted assets) Consolidated $ 345,539 13.5 % $ 205,602 8.0 % $ NA NA Bank 347,433 13.5 205,624 8.0 257,030 10.0 % Tier 1 capital (to risk weighted assets) Consolidated 329,858 12.8 154,201 6.0 NA NA Bank 331,752 12.9 154,218 6.0 205,624 8.0 Common equity tier 1 (to risk weighted assets) Consolidated 280,171 10.9 115,804 4.5 NA NA Bank 331,752 12.9 115,664 4.5 167,070 6.5 Tier 1 capital (to average assets) Consolidated 329,858 11.6 114,138 4.0 NA NA Bank 331,752 11.6 114,280 4.0 142,850 5.0 Our consolidated capital levels as of March 31, 2016 and December 31, 2015 include $42.3 million and $53.1 million, respectively, of trust preferred securities subject to certain limitations. Under applicable Federal Reserve guidelines, the trust preferred securities constitute a restricted core capital element. The guidelines provide that the aggregate amount of restricted core elements that may be included in our Tier 1 capital must not exceed 25% of the sum of all core capital elements, including restricted core capital elements, net of goodwill less any associated deferred tax liability. Our ability to include the trust preferred securities in Tier 1 capital in accordance with the guidelines is not affected by the provision of the Dodd-Frank Act generally restricting such treatment, because (i) the trust preferred securities were issued before May 19, 2010, and (ii) our total consolidated assets as of December 31, 2009 were less than $15.0 billion. As of March 31, 2016 and December 31, 2015, all $42.3 million and $53.1 million, respectively, of the trust preferred securities were included in our consolidated Tier 1 capital. Our regulatory capital calculations and the minimum requirements to be categorized as well capitalized and adequately capitalized under the prompt corrective action regulations were impacted by BASEL III, which became effective January 1, 2015 and are included in the tables above. The net impact on our regulatory capital ratios and our overall capital position was not material. On January 26, 2016, we closed on a repurchase of trust preferred securities that were auctioned as part of a pooled collateralized debt obligation (“Fund”). The Fund owned $11.0 million of the $32.0 million in trust preferred securities that had been issued by Mercantile Bank Capital Trust I, a wholly-owned business trust subsidiary. The $11.0 million in trust preferred securities was retired upon the repurchase, resulting in a commensurate reduction in the related Floating Rate Junior Subordinate Note, leaving $21.0 million outstanding. Our accepted bid equated to 73% of the $11.0 million par value, with the 27% discount resulting in a pre-tax gain of approximately $3.0 million (after-tax gain of approximately $1.8 million, or $0.11 per diluted share). On a pro forma basis as of December 31, 2015, the repurchase resulted in a nine basis point increase in our tangible equity to tangible assets ratio and an $0.11 increase in our tangible book value per share, but an approximately 35 basis point decline in our regulatory tier 1 capital and total risk-based capital ratios. The repurchase was funded via a cash dividend from our bank, resulting in a similar decline of approximately 35 basis points in the regulatory capital ratios. Subsequent to the repurchase, the regulatory capital ratios of both Mercantile and our bank remained well above the minimum thresholds to be categorized as well capitalized. Our and our bank’s ability to pay cash and stock dividends is subject to limitations under various laws and regulations and to prudent and sound banking practices. On January 14, 2016, our Board of Directors declared a cash dividend on our common stock in the amount of $0.16 per share that was paid on March 23, 2016 to shareholders of record as of March 11, 2016. On April 14, 2016, our Board of Directors declared a cash dividend on our common stock in the amount of $0.16 per share that will be paid on June 23, 2016 to shareholders of record as of June 10, 2016. On January 30, 2015, we announced that our Board of Directors had authorized a new program to repurchase up to $20.0 million of our common stock from time to time in open market transactions at prevailing market prices or by other means in accordance with applicable regulations. During the first three months of 2016, we purchased approximately 148,000 shares of common stock at an average price of $22.07, totaling about $3.3 million. Since the program’s inception, we have purchased approximately 936,000 shares of common stock at an average price of $20.32, totaling about $19.0 million. On April 19, 2016, we announced that our Board of Directors had authorized a $15.0 million expansion of the existing common stock repurchase program. All common stock repurchases to date have been funded from cash dividends paid to us from our bank, and we expect future common stock repurchases to be funded in the same manner.

Subordinated debentures were issued to the trusts in return for the proceeds raised from the issuance of the trust preferred securities. The trusts are not consolidated, but instead we report the subordinated debentures issued to the trusts as a liability.
Earnings Per Share, Policy [Policy Text Block]	Earnings Per Share Approximately 150,000 unvested restricted shares were included in determining both basic and diluted earnings per share for the three months ended March 31, 2016. In addition, stock options for approximately 118,000 shares of common stock were included in determining diluted earnings per share for the three months ended March 31, 2016. Stock options for approximately 10,000 shares of common stock were antidilutive and not included in determining diluted earnings per share for the three months ended March 31, 2016. Approximately 101,000 unvested restricted shares were included in determining both basic and diluted earnings per share for the three months ended March 31, 2015. In addition, stock options for approximately 121,000 shares of common stock were included in determining diluted earnings per share for the three months ended March 31, 2015. Stock options for approximately 118,000 shares of common stock were antidilutive and not included in determining diluted earnings per share for the three months ended March 31, 2015. Securities Interest income includes amortization of purchase premiums and accretion of discounts. Premiums and discounts on securities are amortized or accreted on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Declines in the fair value of debt securities below their amortized cost that are other than temporary (“OTTI”) are reflected in earnings or other comprehensive income, as appropriate. For those debt securities whose fair value is less than their amortized cost, we consider our intent to sell the security, whether it is more likely than not that we will be required to sell the security before recovery and whether we expect to recover the entire amortized cost of the security based on our assessment of the issuer’s financial condition. In analyzing an issuer’s financial condition, we consider whether the securities are issued by the federal government or its agencies, and whether downgrades by bond rating agencies have occurred. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement, and 2) OTTI related to other factors, such as liquidity conditions in the market or changes in market interest rates, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost. Loans Interest income on commercial loans and mortgage loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Consumer and credit card loans are typically charged off no later than when they are 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal and interest is considered doubtful. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Loans Held for Sale Mortgage loans held for sale are generally sold with servicing rights retained. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold, which is reduced by the cost allocated to the servicing right. We generally lock in the sale price to the purchaser of the loan at the same time we make a rate commitment to the borrower. These mortgage banking activities are not designated as hedges and are carried at fair value. The net gain or loss on mortgage banking derivatives is included in the gain on sale of loans. Mortgage loans serviced for others totaled approximately $600 million as of March 31, 2016. Mortgage Banking Activities Servicing fee income is recorded for fees earned for serving mortgage loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Amortization of mortgage loan servicing rights is netted against mortgage loan servicing income and recorded in mortgage banking activities in the income statement. Troubled Debt Restructurings In accordance with current accounting guidance, loans modified as troubled debt restructurings are, by definition, considered to be impaired loans. Impairment for these loans is measured on a loan-by-loan basis similar to other impaired loans as described below under “Allowance for Loan Losses.” Certain loans modified as troubled debt restructurings may have been previously measured for impairment under a general allowance methodology (i.e.

Loans and Leases Receivable, Mortgage Banking Activities, Policy [Policy Text Block]	Mortgage Banking Activities Servicing fee income is recorded for fees earned for serving mortgage loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Amortization of mortgage loan servicing rights is netted against mortgage loan servicing income and recorded in mortgage banking activities in the income statement.
Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]	Troubled Debt Restructurings In accordance with current accounting guidance, loans modified as troubled debt restructurings are, by definition, considered to be impaired loans. Impairment for these loans is measured on a loan-by-loan basis similar to other impaired loans as described below under “Allowance for Loan Losses.” Certain loans modified as troubled debt restructurings may have been previously measured for impairment under a general allowance methodology (i.e., pooling), thus at the time the loan is modified as a troubled debt restructuring the allowance will be impacted by the difference between the results of these two measurement methodologies. Loans modified as troubled debt restructurings that subsequently default are factored into the determination of the allowance in the same manner as other defaulted loans.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses A loan is considered to be impaired when, based on current information and events, it is probable we will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of delay, the reasons for delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of collateral if the loan is collateral dependent.
Derivatives, Policy [Policy Text Block]	Derivatives Changes in the fair value of derivatives that are designated, for accounting purposes, as a hedge of the variability of cash flows to be received on various loans and are effective are reported in other comprehensive income. They are later reclassified into earnings in the same periods during which the hedged transaction affects earnings and are included in the line item in which the hedged cash flows are recorded. If hedge accounting does not apply, changes in the fair value of derivatives are recognized immediately in current earnings as interest income or expense. If designated as a hedge, we formally document the relationship between derivatives as hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions. This documentation includes linking cash flow hedges to specific assets and liabilities on the balance sheet. If designated as a hedge, we also formally assess, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in cash flows of the hedged items. Ineffective hedge gains and losses are recognized immediately in current earnings as noninterest income or expense. We discontinue hedge accounting when we determine the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative is settled or terminates, or treatment of the derivative as a hedge is no longer appropriate or intended.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Core Deposit Intangible The core deposit intangible that arose from the Firstbank Corporation acquisition was initially measured at fair value and is being amortized into noninterest expense over a ten-year period using the sum-of-the-years-digits methodology.
