New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Pending Accounting Standards Updates	Accounting Standards Updates Pending Accounting Standards Updates ASU No. 2017-09: “ Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting” In May 2017, ASU No. 2017-09 provided guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718. The current disclosure requirements in Topic 718 apply regardless of whether an entity is required to apply modification accounting under the amendments in this updated. An entity should account for the effects of a modification unless all of the following are met: 1. The fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification. 2. The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified. 3. The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2017 and is not expected to have a significant impact on our operating results or financial statement disclosures.

As the auction rate money market preferred and preferred stocks have continual call dates, they are not reported by a specific maturity group.

Such analyses considered, among other factors, the following criteria: • Has the value of the investment declined more than what is deemed to be reasonable based on a risk and maturity adjusted discount rate? • Is the investment credit rating below investment grade? • Is it probable the issuer will be unable to pay the amount when due? • Is it more likely than not that we will have to sell the security before recovery of its cost basis? • Has the duration of the investment been extended? During the fourth quarter of 2016, we identified one municipal bond as other-than-temporarily impaired. While management estimated the OTTI to be realized, we also engaged the services of an independent investment valuation firm to estimate the amount of impairment as of December 31, 2016 . The valuation calculated the estimated market value utilizing two different approaches: 1) Market - Appraisal and Comparable Investments 2) Income - Discounted Cash Flow Method The two methods were then weighted, with a higher weighting applied to the Market approach, to determine the estimated impairment. As a result of this analysis, we recognized an OTTI of $770 in earnings for the year ended December 31, 2016. Based on analysis of this bond, there was no additional OTTI recognized as of June 30, 2017 . Based on our analyses, the fact that we have asserted that we do not have the intent to sell AFS securities in an unrealized loss position, and considering it is unlikely that we will have to sell any AFS securities in an unrealized loss position before recovery of their cost basis, we do not believe that the values of any other AFS securities are other-than-temporarily impaired as of June 30, 2017 or December 31, 2016 , with the exception of the one municipal bond discussed above.

Loans and ALLL

Loans and ALLL	6 Months Ended
	Jun. 30, 2017
Receivables [Abstract]
Loans and ALLL	Loans and ALLL We grant commercial, agricultural, residential real estate, and consumer loans to customers situated primarily in Clare, Gratiot, Isabella, Mecosta, Midland, Montcalm, and Saginaw counties in Michigan. The ability of the borrowers to honor their repayment obligations is often dependent upon the real estate, agricultural, manufacturing, retail, gaming, tourism, higher education, and general economic conditions of this region. Substantially all of our consumer and residential real estate loans are secured by various items of property, while commercial loans are secured primarily by real estate, business assets, and personal guarantees. A portion of loans are unsecured. Loans that we have the intent and ability to hold in our portfolio are reported at their outstanding principal balance adjusted for any charge-offs , the ALLL , and any deferred fees or costs. Interest income is accrued over the term of the loan based on the principal amount outstanding. Loan origination fees and certain direct loan origination costs are capitalized and recognized as a component of interest income over the term of the loan using the level yield method. The accrual of interest on commercial, agricultural, and residential real estate loans is discontinued at the time the loan is 90 days or more past due unless the credit is well-secured and in the process of collection. Upon transferring the loans to nonaccrual status, we perform an evaluation to determine the net realizable value of the underlying collateral. This evaluation is used to help determine if any charge-offs are necessary. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. For loans that are placed on nonaccrual status or charged-off , all interest accrued in the current calendar year, but not collected, is reversed against interest income while interest accrued in prior calendar years, but not collected, is charged against the ALLL . Loans may be returned to accrual status after six months of continuous performance. Commercial and agricultural loans include loans for commercial real estate, commercial operating loans, advances to mortgage brokers, farmland and agricultural production, and states and political subdivisions. Repayment of these loans is dependent upon the successful operation and management of a business. We minimize our risk by limiting the amount of direct credit exposure to any one borrower to $15,000 . Borrowers with direct credit needs of more than $15,000 are serviced through the use of loan participations with other commercial banks. Commercial and agricultural real estate loans commonly require loan-to-value limits of 80% or less. Depending upon the type of loan, past credit history, and current operating results, we may require the borrower to pledge accounts receivable, inventory, and property and equipment. Personal guarantees are generally required from the owners of closely held corporations, partnerships, and sole proprietorships. In addition, we require annual financial statements, prepare cash flow analyses, and review credit reports. We entered into a mortgage purchase program in 2016 with a financial institution where we participate in advances to mortgage brokers ("advances"). The mortgage brokers originate residential mortgage loans with the intent to sell them on the secondary market. We participate in the advance to the mortgage broker, which is secured by the underlying mortgage loan, until it is ultimately sold on the secondary market. As such, the average life of each participated advance is approximately 20 - 30 days. Funds from the sale of the loan are used to payoff our participation in the advance to the mortgage broker. We classify these advances as commercial loans and include the outstanding balance in commercial loans on our balance sheet. Under the participation agreement, we committed to a maximum outstanding aggregate amount of $30,000 . The difference between our outstanding balances and the maximum outstanding aggregate amount is classified as “ Unfunded commitments under lines of credit ” in the “ Contractual Obligations and Loan Commitments ” section of the Management's Discussion and Analysis of Financial Condition and Results of Operations of this report. We offer adjustable rate mortgages, construction loans, and fixed rate residential real estate loans which have amortization periods up to a maximum of 30 years. We consider the anticipated direction of interest rates, balance sheet duration, the sensitivity of our balance sheet to changes in interest rates, and overall loan demand to determine whether or not to sell fixed rate loans to Freddie Mac . Our lending policies generally limit the maximum loan-to-value ratio on residential real estate loans to 97% of the lower of the appraised value of the property or the purchase price, with the condition that private mortgage insurance is required on loans with loan-to-value ratios in excess of 80% . Underwriting criteria for originated residential real estate loans include: • Evaluation of the borrower’s ability to make monthly payments. • Evaluation of the value of the property securing the loan. • Ensuring the payment of principal, interest, taxes, and hazard insurance does not exceed 28% of a borrower’s gross income. • Ensuring all debt servicing does not exceed 36% of income. • Verification of acceptable credit reports. • Verification of employment, income, and financial information. Appraisals are performed by independent appraisers and reviewed for appropriateness. All originated mortgage loan requests are reviewed by our mortgage loan committee or through a secondary market underwriting system; loans in excess of $500 require the approval of our Internal Loan Committee, the Executive Loan Committee, the Board of Directors’ Loan Committee, or the Board of Directors. Consumer loans include secured and unsecured personal loans. Loans are amortized for a period of up to 12 years based on the age and value of the underlying collateral. The underwriting emphasis is on a borrower’s perceived intent and ability to pay rather than collateral value. No consumer loans are sold to the secondary market. The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the ALLL when we believe the uncollectability of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the ALLL . The appropriateness of the ALLL is evaluated on a quarterly basis and is based upon a periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The primary factors behind the determination of the level of the ALLL are specific allocations for impaired loans, historical loss percentages, as well as unallocated components. Specific allocations for impaired loans are primarily determined based on the difference between the loan’s outstanding balance and 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 the collateral, less cost to sell. Historical loss allocations are calculated at the loan class and segment levels based on a migration analysis of the loan portfolio, with the exception of advances to mortgage brokers, over the preceding five years. With no historical losses on advances to mortgage brokers, there is no allocation in the commercial segment displayed in the following tables based on historical loss factors. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. A summary of changes in the ALLL and the recorded investment in loans by segments follows: Allowance for Loan Losses Three Months Ended June 30, 2017 Commercial Agricultural Residential Real Estate Consumer Unallocated Total April 1, 2017 $ 1,771 $ 527 $ 3,098 $ 671 $ 1,433 $ 7,500 Charge-offs (25 ) — — (44 ) — (69 ) Recoveries 55 — 63 42 — 160 Provision for loan losses 177 (52 ) (563 ) (86 ) 533 9 June 30, 2017 $ 1,978 $ 475 $ 2,598 $ 583 $ 1,966 $ 7,600 Allowance for Loan Losses Six Months Ended June 30, 2017 Commercial Agricultural Residential Real Estate Consumer Unallocated Total January 1, 2017 $ 1,814 $ 884 $ 2,664 $ 624 $ 1,414 $ 7,400 Charge-offs (52 ) — (43 ) (118 ) — (213 ) Recoveries 188 — 99 90 — 377 Provision for loan losses 28 (409 ) (122 ) (13 ) 552 36 June 30, 2017 $ 1,978 $ 475 $ 2,598 $ 583 $ 1,966 $ 7,600 Allowance for Loan Losses and Recorded Investment in Loans June 30, 2017 Commercial Agricultural Residential Real Estate Consumer Unallocated Total ALLL Individually evaluated for impairment $ 783 $ — $ 1,672 $ — $ — $ 2,455 Collectively evaluated for impairment 1,195 475 926 583 1,966 5,145 Total $ 1,978 $ 475 $ 2,598 $ 583 $ 1,966 $ 7,600 Loans Individually evaluated for impairment $ 7,362 $ 11,125 $ 8,628 $ 20 $ 27,135 Collectively evaluated for impairment 593,222 119,829 261,579 46,732 1,021,362 Total $ 600,584 $ 130,954 $ 270,207 $ 46,752 $ 1,048,497 Allowance for Loan Losses Three Months Ended June 30, 2016 Commercial Agricultural Residential Real Estate Consumer Unallocated Total April 1, 2016 $ 2,421 $ 336 $ 3,130 $ 540 $ 1,073 $ 7,500 Charge-offs (32 ) — (128 ) (48 ) — (208 ) Recoveries 189 — 45 62 — 296 Provision for loan losses (459 ) 198 83 (13 ) 203 12 June 30, 2016 $ 2,119 $ 534 $ 3,130 $ 541 $ 1,276 $ 7,600 Allowance for Loan Losses Six Months Ended June 30, 2016 Commercial Agricultural Residential Real Estate Consumer Unallocated Total January 1, 2016 $ 2,171 $ 329 $ 3,330 $ 522 $ 1,048 $ 7,400 Charge-offs (48 ) — (369 ) (132 ) — (549 ) Recoveries 278 92 95 116 — 581 Provision for loan losses (282 ) 113 74 35 228 168 June 30, 2016 $ 2,119 $ 534 $ 3,130 $ 541 $ 1,276 $ 7,600 Allowance for Loan Losses and Recorded Investment in Loans December 31, 2016 Commercial Agricultural Residential Real Estate Consumer Unallocated Total ALLL Individually evaluated for impairment $ 741 $ 1 $ 1,629 $ — $ — $ 2,371 Collectively evaluated for impairment 1,073 883 1,035 624 1,414 5,029 Total $ 1,814 $ 884 $ 2,664 $ 624 $ 1,414 $ 7,400 Loans Individually evaluated for impairment $ 7,859 $ 5,545 $ 8,638 $ 26 $ 22,068 Collectively evaluated for impairment 567,805 120,947 257,412 42,383 988,547 Total $ 575,664 $ 126,492 $ 266,050 $ 42,409 $ 1,010,615 The following table displays the credit quality indicators for commercial and agricultural credit exposures based on internally assigned credit risk ratings as of: June 30, 2017 Commercial Agricultural Real Estate Other Advances to Mortgage Brokers Total Real Estate Other Total Total Rating 1 - Excellent $ 26 $ 232 $ — $ 258 $ — $ — $ — $ 258 2 - High quality 7,479 15,878 — 23,357 3,088 1,006 4,094 27,451 3 - High satisfactory 103,672 45,853 19,914 169,439 21,435 9,306 30,741 200,180 4 - Low satisfactory 320,610 71,958 — 392,568 48,109 20,740 68,849 461,417 5 - Special mention 4,253 1,899 — 6,152 11,015 9,054 20,069 26,221 6 - Substandard 6,343 2,450 — 8,793 4,379 1,830 6,209 15,002 7 - Vulnerable 17 — — 17 466 526 992 1,009 8 - Doubtful — — — — — — — — Total $ 442,400 $ 138,270 $ 19,914 $ 600,584 $ 88,492 $ 42,462 $ 130,954 $ 731,538 December 31, 2016 Commercial Agricultural Real Estate Other Advances to Mortgage Brokers Total Real Estate Other Total Total Rating 1 - Excellent $ 28 $ 438 $ — $ 466 $ — $ — $ — $ 466 2 - High quality 11,821 12,091 19,688 43,600 3,566 1,426 4,992 48,592 3 - High satisfactory 103,529 41,982 — 145,511 21,657 11,388 33,045 178,556 4 - Low satisfactory 299,317 74,432 — 373,749 48,955 22,715 71,670 445,419 5 - Special mention 3,781 1,178 — 4,959 6,009 3,085 9,094 14,053 6 - Substandard 5,901 1,474 — 7,375 3,650 3,508 7,158 14,533 7 - Vulnerable 4 — — 4 — 533 533 537 8 - Doubtful — — — — — — — — Total $ 424,381 $ 131,595 $ 19,688 $ 575,664 $ 83,837 $ 42,655 $ 126,492 $ 702,156 Internally assigned credit risk ratings are reviewed, at a minimum, when loans are renewed or when management has knowledge of improvements or deterioration of the credit quality of individual credits. Descriptions of the internally assigned credit risk ratings for commercial and agricultural loans are as follows: 1. EXCELLENT – Substantially Risk Free Credit has strong financial condition and solid earnings history, characterized by: • High liquidity, strong cash flow, low leverage. • Unquestioned ability to meet all obligations when due. • Experienced management, with management succession in place. • Secured by cash. 2. HIGH QUALITY – Limited Risk Credit with sound financial condition and a positive trend in earnings supplemented by: • Favorable liquidity and leverage ratios. • Ability to meet all obligations when due. • Management with successful track record. • Steady and satisfactory earnings history. • If loan is secured, collateral is of high quality and readily marketable. • Access to alternative financing. • Well defined primary and secondary source of repayment. • If supported by guaranty, the financial strength and liquidity of the guarantor(s) are clearly evident. 3. HIGH SATISFACTORY – Reasonable Risk Credit with satisfactory financial condition and further characterized by: • Working capital adequate to support operations. • Cash flow sufficient to pay debts as scheduled. • Management experience and depth appear favorable. • Loan performing according to terms. • If loan is secured, collateral is acceptable and loan is fully protected. 4. LOW SATISFACTORY – Acceptable Risk Credit with bankable risks, although some signs of weaknesses are shown: • Would include most start-up businesses. • Occasional instances of trade slowness or repayment delinquency – may have been 10 - 30 days slow within the past year. • Management’s abilities are apparent, yet unproven. • Weakness in primary source of repayment with adequate secondary source of repayment. • Loan structure generally in accordance with policy. • If secured, loan collateral coverage is marginal. • Adequate cash flow to service debt, but coverage is low. To be classified as less than satisfactory, only one of the following criteria must be met. 5. SPECIAL MENTION – Criticized Credit constitutes an undue and unwarranted credit risk but not to the point of justifying a classification of substandard. The credit risk may be relatively minor yet constitute an unwarranted risk in light of the circumstances surrounding a specific loan: • Downward trend in sales, profit levels, and margins. • Impaired working capital position. • Cash flow is strained in order to meet debt repayment. • Loan delinquency ( 30 - 60 days) and overdrafts may occur. • Shrinking equity cushion. • Diminishing primary source of repayment and questionable secondary source. • Management abilities are questionable. • Weak industry conditions. • Litigation pending against the borrower. • Collateral or guaranty offers limited protection. • Negative debt service coverage, however the credit is well collateralized and payments are current. 6. SUBSTANDARD – Classified Credit where the borrower’s current net worth, paying capacity, and value of the collateral pledged is inadequate. There is a distinct possibility that we will implement collection procedures if the loan deficiencies are not corrected. In addition, the following characteristics may apply: • Sustained losses have severely eroded the equity and cash flow. • Deteriorating liquidity. • Serious management problems or internal fraud. • Original repayment terms liberalized. • Likelihood of bankruptcy. • Inability to access other funding sources. • Reliance on secondary source of repayment. • Litigation filed against borrower. • Collateral provides little or no value. • Requires excessive attention of the loan officer. • Borrower is uncooperative with loan officer. 7. VULNERABLE – Classified Credit is considered “Substandard” and warrants placing on nonaccrual status. Risk of loss is being evaluated and exit strategy options are under review. Other characteristics that may apply: • Insufficient cash flow to service debt. • Minimal or no payments being received. • Limited options available to avoid the collection process. • Transition status, expect action will take place to collect loan without immediate progress being made. 8. DOUBTFUL – Workout Credit has all the weaknesses inherent in a “Substandard” loan with the added characteristic that collection and/or liquidation is pending. The possibility of a loss is extremely high, but its classification as a loss is deferred until liquidation procedures are completed, or reasonably estimable. Other characteristics that may apply: • Normal operations are severely diminished or have ceased. • Seriously impaired cash flow. • Original repayment terms materially altered. • Secondary source of repayment is inadequate. • Survivability as a “going concern” is impossible. • Collection process has begun. • Bankruptcy petition has been filed. • Judgments have been filed. • Portion of the loan balance has been charged-off . Our primary credit quality indicator for residential real estate and consumer loans is the individual loan’s past due aging.

There has been a charge-off of its principal balance (in whole or in part); 2. The loan has been classified as a TDR ; or 3. The loan is in nonaccrual status. Impairment is measured on a loan-by-loan basis for commercial and agricultural loans by comparing the loan’s outstanding balance to 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 the collateral, less cost to sell, if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Impairment is measured on a loan-by-loan basis for residential real estate and consumer loans by comparing the loan’s unpaid principal balance to the present value of expected future cash flows discounted at the loan’s effective interest rate. We do not recognize interest income on impaired loans in nonaccrual status. For impaired loans not classified as nonaccrual , interest income is recognized daily, as earned, according to the terms of the loan agreement and the principal amount outstanding.

Troubled Debt Restructurings Loan modifications are considered to be TDRs when the modification includes terms outside of normal lending practices to a borrower who is experiencing financial difficulties. Typical concessions granted include, but are not limited to: • Agreeing to interest rates below prevailing market rates for debt with similar risk characteristics. • Extending the amortization period beyond typical lending guidelines for loans with similar risk characteristics. • Forgiving principal. • Forgiving accrued interest. To determine if a borrower is experiencing financial difficulties, factors we consider include: • The borrower is currently in default on any of their debt. • The borrower would likely default on any of their debt if the concession was not granted. • The borrower’s cash flow was insufficient to service all of their debt if the concession was not granted. • The borrower has declared, or is in the process of declaring, bankruptcy. • The borrower is unlikely to continue as a going concern (if the entity is a business).

As such, TDRs , including TDRs that have been modified in the past 12 months that subsequently defaulted, are analyzed in the same manner as other impaired loans within their respective loan segment. We had no loans that defaulted in the three and six month periods ended June 30, 2017 and June 30, 2016 which were modified within 12 months prior to the default date.

As of June 30, 2017 , we had the ability to borrow up to an additional $119,462 , based on assets pledged as collateral. We had no investment securities that are restricted to be pledged for specific purposes. Derivative Instruments We enter into interest rate swaps to manage exposure to interest rate risk and variability in cash flows. The interest rate swaps, associated with our variable rate borrowings, are designated upon inception as cash flow hedges of forecasted interest payments. We enter into LIBOR-based interest rate swaps that involve the receipt of variable amounts in exchange for fixed rate payments, in effect converting variable rate debt to fixed rate debt. Cash flow hedges are assessed for effectiveness using regression analysis. The effective portion of changes in fair value are recorded in OCI and subsequently reclassified into interest expense in the same period in which the related interest on the variable rate borrowings affects earnings. In the event that a portion of the changes in fair value were determined to be ineffective, the ineffective amount would be recorded in earnings. The following tables provide information on derivatives related to variable rate borrowings as of: June 30, 2017 Pay Rate Receive Rate Remaining Life (Years) Notional Amount Balance Sheet Location Fair Value Derivatives designated as hedging instruments Cash Flow Hedges: Interest rate swaps 1.56 % 3-Month LIBOR 3.8 $ 10,000 Other Assets $ 204 December 31, 2016 Pay Rate Receive Rate Remaining Life (Years) Notional Amount Balance Sheet Location Fair Value Derivatives designated as hedging instruments Cash Flow Hedges: Interest rate swaps 1.56 % 3-Month LIBOR 4.3 $ 10,000 Other Assets $ 248 Derivatives contain an element of credit risk which arises from the possibility that we will incur a loss as a result of a counterparty failing to meet its contractual obligations. Credit risk is minimized through counterparty collateral, transaction limits and monitoring procedures. We also manage dealer credit risk by entering into interest rate derivatives only with primary and highly rated counterparties, the use of ISDA master agreements and counterparties limits. We do not anticipate any losses from failure of interest rate derivative counterparties to honor their obligations.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Following is a description of the valuation methodologies, key inputs, and an indication of the level of the fair value hierarchy in which the assets or liabilities are classified. Cash and cash equivalents : The carrying amounts of cash and demand deposits due from banks and interest bearing balances due from banks approximate fair values. As such, we classify cash and cash equivalents as Level 1. AFS securities : AFS securities are recorded at fair value on a recurring basis. Level 1 fair value measurement is based upon quoted prices for identical instruments. Level 2 fair value measurement is based upon quoted prices for similar instruments. If quoted prices are not available, fair values are measured using independent pricing models or other model based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss and liquidity assumptions. The values for Level 1 and Level 2 investment securities are generally obtained from an independent third party. On a quarterly basis, we compare the values provided to alternative pricing sources. Mortgage loans AFS : Mortgage loans AFS are carried at the lower of cost or fair value. The fair value of mortgage loans AFS are based on the price secondary markets are currently offering for portfolios with similar characteristics. As such, we classify mortgage loans AFS subject to nonrecurring fair value adjustments as Level 2. Loans : For variable rate loans with no significant change in credit risk, fair values are based on carrying values. Fair values for fixed rate loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The resulting amounts are adjusted to estimate the effect of changes in the credit quality of borrowers since the loans were originated. As such, we classify loans as Level 3 assets. We do not record loans at fair value on a recurring basis. However, from time-to-time , loans are classified as impaired and a specific allowance for loan losses may be established. Loans for which it is probable that payment of interest and principal will be significantly different than the contractual terms of the original loan agreement are considered impaired. Once a loan is identified as impaired, we measure the estimated impairment. The fair value of impaired loans is estimated using one of several methods, including 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 the collateral, less cost to sell, if the loan is collateral dependent. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. We review the net realizable values of the underlying collateral for collateral dependent impaired loans on at least a quarterly basis for all loan types. To determine the collateral value, we utilize independent appraisals, broker price opinions, or internal evaluations. We review these valuations to determine whether an additional discount should be applied given the age of market information that may have been considered as well as other factors such as costs to sell an asset if it is determined that the collateral will be liquidated in connection with the ultimate settlement of the loan. We use these valuations to determine if any specific reserves or charge-offs are necessary. We may obtain new valuations in certain circumstances, including when there has been significant deterioration in the condition of the collateral, if the foreclosure process has begun, or if the existing valuation is deemed to be outdated. The following tables list the quantitative fair value information about impaired loans as of: June 30, 2017 Valuation Technique Fair Value Unobservable Input Range Discount applied to collateral: Real Estate 20% - 30% Equipment 20% - 45% Discounted value $15,117 Cash crop inventory 30% - 40% Liquor license 75% Furniture, fixtures & equipment 40% - 45% December 31, 2016 Valuation Technique Fair Value Unobservable Input Range Discount applied to collateral: Real Estate 20% - 30% Equipment 20% - 45% Discounted value $9,166 Cash crop inventory 30% - 40% Liquor license 75% Furniture, fixtures & equipment 45% Discount factors with ranges are based on the age of the independent appraisal, broker price opinion, or internal evaluation. Accrued interest receivable : The carrying amounts of accrued interest receivable approximate fair value. As such, we classify accrued interest receivable as Level 1. Equity securities without readily determinable fair values : Included in equity securities without readily determinable fair values are FHLB stock and FRB stock as well as our minority ownership interest in Corporate Settlement Solutions, LLC . The investment in Corporate Settlement Solutions, LLC , a title insurance agency, was made in the first quarter 2008 and we account for our investment under the equity method of accounting. The lack of an active market, or other independent sources to validate fair value estimates coupled with the impact of future capital calls and transfer restrictions, is an inherent limitation in the valuation process. As the fair values of these investments are not readily determinable, they are not disclosed under a specific fair value hierarchy; however, they are reviewed quarterly for impairment. If we were to record an impairment adjustment related to these securities, it would be classified as a nonrecurring Level 3 fair value adjustment. During 2017 and 2016 , there were no impairments recorded on equity securities without readily determinable fair values. Foreclosed assets : Upon transfer from the loan portfolio, foreclosed assets (which are included in other assets) are adjusted to and subsequently carried at the lower of carrying value or fair value less costs to sell. Net realizable value is based upon independent market prices, appraised values of the collateral, or management’s estimation of the value of the collateral. Due to the inherent level of estimation in the valuation process, we classify foreclosed assets as nonrecurring Level 3. The table below lists the quantitative fair value information related to foreclosed assets as of: June 30, 2017 Valuation Technique Fair Value Unobservable Input Range Discount applied to collateral: Discounted value $ 229 Real Estate 20% - 30% December 31, 2016 Valuation Technique Fair Value Unobservable Input Range Discount applied to collateral: Discounted value $ 231 Real Estate 20% - 30% Discount factors with ranges are based on the age of the independent appraisal, broker price opinion, or internal evaluations. Goodwill and other intangible assets : Acquisition intangibles and goodwill are evaluated for potential impairment on at least an annual basis. Acquisition intangibles and goodwill are typically qualitatively evaluated to determine if it is more likely than not that the carrying balance is impaired. If it is determined that the carrying balance of acquisition intangibles or goodwill is more likely than not to be impaired, we perform a cash flow valuation to determine the extent of the potential impairment. If the testing resulted in impairment, we would classify goodwill and other acquisition intangibles subjected to nonrecurring fair value adjustments as Level 3. During 2017 and 2016 , there were no impairments recorded on goodwill and other acquisition intangibles. OMSR : OMSR (which are included in other assets) are subject to impairment testing. To test for impairment, we utilize a discounted cash flow analysis using interest rates and prepayment speed assumptions currently quoted for comparable instruments and discount rates. If the valuation model reflects a value less than the carrying value, OMSR are adjusted to fair value through a valuation allowance as determined by the model. As such, we classify OMSR subject to nonrecurring fair value adjustments as Level 2. Deposits : The fair value of demand, savings, and money market deposits are equal to their carrying amounts and are classified as Level 1. Fair values for variable rate certificates of deposit approximate their carrying value. Fair values for fixed rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. As such, fixed rate certificates of deposit are classified as Level 2. Borrowed funds : The carrying amounts of federal funds purchased, borrowings under overnight repurchase agreements, and other short-term borrowings maturing within ninety days approximate their fair values. The fair values of other borrowed funds are estimated using discounted cash flow analyses based on current incremental borrowing arrangements. As such, borrowed funds are classified as Level 2. Accrued interest payable: The carrying amounts of accrued interest payable approximate fair value. As such, we classify accrued interest payable as Level 1. Derivative instruments: Derivative instruments, consisting solely of interest rate swaps, are recorded at fair value on a recurring basis. Derivatives qualifying as cash flow hedges, when highly effective, are reported at fair value in other assets or other liabilities on our Consolidated Balance Sheets with changes in value recorded in OCI. Should the hedge no longer be considered effective, the ineffective portion of the change in fair value is recorded directly in earnings in the period in which the change occurs. The fair value of a derivative is determined by quoted market prices and model based valuation techniques. As such, we classify derivative instruments as Level 2. Commitments to extend credit, standby letters of credit, and undisbursed loans: Our commitments to extend credit, standby letters of credit, and undisbursed funds have no carrying amount and are estimated to have no realizable fair value. Historically, a majority of the unused commitments to extend credit have not been drawn upon and, generally, we do not receive fees in connection with these commitments other than standby letter of credit fees, which are not significant. The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Although we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement. Estimated Fair Values of Financial Instruments Not Recorded at Fair Value in their Entirety on a Recurring Basis Disclosure of the estimated fair values of financial instruments, which differ from carrying values, often requires the use of estimates. In cases where quoted market values in an active market are not available, we use present value techniques and other valuation methods to estimate the fair values of our financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used. The carrying amount and estimated fair value of financial instruments not recorded at fair value in their entirety on a recurring basis were as follows as of: June 30, 2017 Carrying Estimated (Level 1) (Level 2) (Level 3) ASSETS Cash and cash equivalents $ 21,834 $ 21,834 $ 21,834 $ — $ — Mortgage loans AFS 1,482 1,493 — 1,493 — Gross loans 1,048,497 1,029,290 — — 1,029,290 Less allowance for loan and lease losses 7,600 7,600 — — 7,600 Net loans 1,040,897 1,021,690 — — 1,021,690 Accrued interest receivable 5,686 5,686 5,686 — — Equity securities without readily determinable fair values (1) 23,401 N/A — — — OMSR 2,490 2,499 — 2,499 — LIABILITIES Deposits without stated maturities 780,243 780,243 780,243 — — Deposits with stated maturities 429,909 427,877 — 427,877 — Borrowed funds 360,940 361,076 — 361,076 — Accrued interest payable 561 561 561 — — December 31, 2016 Carrying Estimated (Level 1) (Level 2) (Level 3) ASSETS Cash and cash equivalents $ 22,894 $ 22,894 $ 22,894 $ — $ — Mortgage loans AFS 1,816 1,836 — 1,836 — Gross loans 1,010,615 991,009 — — 991,009 Less allowance for loan and lease losses 7,400 7,400 — — 7,400 Net loans 1,003,215 983,609 — — 983,609 Accrued interest receivable 6,580 6,580 6,580 — — Equity securities without readily determinable fair values (1) 21,694 N/A — — — OMSR 2,306 2,306 — 2,306 — LIABILITIES Deposits without stated maturities 761,626 761,626 761,626 — — Deposits with stated maturities 433,414 430,088 — 430,088 — Borrowed funds 337,694 336,975 — 336,975 — Accrued interest payable 574 574 574 — — (1) Due to the characteristics of equity securities without readily determinable fair values, they are not disclosed under a specific fair value hierarchy.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation	As used in these notes, as well as in Management's Discussion and Analysis of Financial Condition and Results of Operations , references to “Isabella,” the “Corporation”, “we,” “our,” “us,” and similar terms refer to the consolidated entity consisting of Isabella Bank Corporation and its subsidiaries. Isabella Bank Corporation refers solely to the parent holding company, and Isabella Bank or the “Bank” refer to Isabella Bank Corporation ’s subsidiary, Isabella Bank .
Basis of Accounting	The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, all adjustments considered necessary for a fair presentation have been included. Operating results for the three and six month periods ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 . For further information, refer to our Annual Report on Form 10-K for the year ended December 31, 2016 .
Earnings Per Share	Basic earnings per common share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per common share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued. Potential common shares that may be issued relate solely to outstanding shares in the Directors Plan .
Available-for-sale Securities	As of June 30, 2017 and December 31, 2016 , we conducted an analysis to determine whether any AFS securities currently in an unrealized loss position should be other-than-temporarily impaired. Such analyses considered, among other factors, the following criteria: • Has the value of the investment declined more than what is deemed to be reasonable based on a risk and maturity adjusted discount rate? • Is the investment credit rating below investment grade? • Is it probable the issuer will be unable to pay the amount when due? • Is it more likely than not that we will have to sell the security before recovery of its cost basis? • Has the duration of the investment been extended?
Nonaccrual Loan Status	The accrual of interest on commercial, agricultural, and residential real estate loans is discontinued at the time the loan is 90 days or more past due unless the credit is well-secured and in the process of collection. Upon transferring the loans to nonaccrual status, we perform an evaluation to determine the net realizable value of the underlying collateral. This evaluation is used to help determine if any charge-offs are necessary. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. For loans that are placed on nonaccrual status or charged-off , all interest accrued in the current calendar year, but not collected, is reversed against interest income while interest accrued in prior calendar years, but not collected, is charged against the ALLL . Loans may be returned to accrual status after six months of continuous performance.
Loans Receivable	Loans that we have the intent and ability to hold in our portfolio are reported at their outstanding principal balance adjusted for any charge-offs , the ALLL , and any deferred fees or costs. Interest income is accrued over the term of the loan based on the principal amount outstanding. Loan origination fees and certain direct loan origination costs are capitalized and recognized as a component of interest income over the term of the loan using the level yield method. Commercial and agricultural loans include loans for commercial real estate, commercial operating loans, advances to mortgage brokers, farmland and agricultural production, and states and political subdivisions. Repayment of these loans is dependent upon the successful operation and management of a business. We minimize our risk by limiting the amount of direct credit exposure to any one borrower to $15,000 . Borrowers with direct credit needs of more than $15,000 are serviced through the use of loan participations with other commercial banks. Commercial and agricultural real estate loans commonly require loan-to-value limits of 80% or less. Depending upon the type of loan, past credit history, and current operating results, we may require the borrower to pledge accounts receivable, inventory, and property and equipment. Personal guarantees are generally required from the owners of closely held corporations, partnerships, and sole proprietorships. In addition, we require annual financial statements, prepare cash flow analyses, and review credit reports. We entered into a mortgage purchase program in 2016 with a financial institution where we participate in advances to mortgage brokers ("advances"). The mortgage brokers originate residential mortgage loans with the intent to sell them on the secondary market. We participate in the advance to the mortgage broker, which is secured by the underlying mortgage loan, until it is ultimately sold on the secondary market. As such, the average life of each participated advance is approximately 20 - 30 days. Funds from the sale of the loan are used to payoff our participation in the advance to the mortgage broker. We classify these advances as commercial loans and include the outstanding balance in commercial loans on our balance sheet. Under the participation agreement, we committed to a maximum outstanding aggregate amount of $30,000 . The difference between our outstanding balances and the maximum outstanding aggregate amount is classified as “ Unfunded commitments under lines of credit ” in the “ Contractual Obligations and Loan Commitments ” section of the Management's Discussion and Analysis of Financial Condition and Results of Operations of this report. We offer adjustable rate mortgages, construction loans, and fixed rate residential real estate loans which have amortization periods up to a maximum of 30 years. We consider the anticipated direction of interest rates, balance sheet duration, the sensitivity of our balance sheet to changes in interest rates, and overall loan demand to determine whether or not to sell fixed rate loans to Freddie Mac . Our lending policies generally limit the maximum loan-to-value ratio on residential real estate loans to 97% of the lower of the appraised value of the property or the purchase price, with the condition that private mortgage insurance is required on loans with loan-to-value ratios in excess of 80% . Underwriting criteria for originated residential real estate loans include: • Evaluation of the borrower’s ability to make monthly payments. • Evaluation of the value of the property securing the loan. • Ensuring the payment of principal, interest, taxes, and hazard insurance does not exceed 28% of a borrower’s gross income. • Ensuring all debt servicing does not exceed 36% of income. • Verification of acceptable credit reports. • Verification of employment, income, and financial information. Appraisals are performed by independent appraisers and reviewed for appropriateness. All originated mortgage loan requests are reviewed by our mortgage loan committee or through a secondary market underwriting system; loans in excess of $500 require the approval of our Internal Loan Committee, the Executive Loan Committee, the Board of Directors’ Loan Committee, or the Board of Directors. Consumer loans include secured and unsecured personal loans. Loans are amortized for a period of up to 12 years based on the age and value of the underlying collateral. The underwriting emphasis is on a borrower’s perceived intent and ability to pay rather than collateral value. No consumer loans are sold to the secondary market.
Allowance for Loan Losses	The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the ALLL when we believe the uncollectability of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the ALLL . The appropriateness of the ALLL is evaluated on a quarterly basis and is based upon a periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The primary factors behind the determination of the level of the ALLL are specific allocations for impaired loans, historical loss percentages, as well as unallocated components. Specific allocations for impaired loans are primarily determined based on the difference between the loan’s outstanding balance and 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 the collateral, less cost to sell. Historical loss allocations are calculated at the loan class and segment levels based on a migration analysis of the loan portfolio, with the exception of advances to mortgage brokers, over the preceding five years. With no historical losses on advances to mortgage brokers, there is no allocation in the commercial segment displayed in the following tables based on historical loss factors. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.
Internal Credit Risk Ratings	Internally assigned credit risk ratings are reviewed, at a minimum, when loans are renewed or when management has knowledge of improvements or deterioration of the credit quality of individual credits. Descriptions of the internally assigned credit risk ratings for commercial and agricultural loans are as follows: 1. EXCELLENT – Substantially Risk Free Credit has strong financial condition and solid earnings history, characterized by: • High liquidity, strong cash flow, low leverage. • Unquestioned ability to meet all obligations when due. • Experienced management, with management succession in place. • Secured by cash. 2. HIGH QUALITY – Limited Risk Credit with sound financial condition and a positive trend in earnings supplemented by: • Favorable liquidity and leverage ratios. • Ability to meet all obligations when due. • Management with successful track record. • Steady and satisfactory earnings history. • If loan is secured, collateral is of high quality and readily marketable. • Access to alternative financing. • Well defined primary and secondary source of repayment. • If supported by guaranty, the financial strength and liquidity of the guarantor(s) are clearly evident. 3. HIGH SATISFACTORY – Reasonable Risk Credit with satisfactory financial condition and further characterized by: • Working capital adequate to support operations. • Cash flow sufficient to pay debts as scheduled. • Management experience and depth appear favorable. • Loan performing according to terms. • If loan is secured, collateral is acceptable and loan is fully protected. 4. LOW SATISFACTORY – Acceptable Risk Credit with bankable risks, although some signs of weaknesses are shown: • Would include most start-up businesses. • Occasional instances of trade slowness or repayment delinquency – may have been 10 - 30 days slow within the past year. • Management’s abilities are apparent, yet unproven. • Weakness in primary source of repayment with adequate secondary source of repayment. • Loan structure generally in accordance with policy. • If secured, loan collateral coverage is marginal. • Adequate cash flow to service debt, but coverage is low. To be classified as less than satisfactory, only one of the following criteria must be met. 5. SPECIAL MENTION – Criticized Credit constitutes an undue and unwarranted credit risk but not to the point of justifying a classification of substandard. The credit risk may be relatively minor yet constitute an unwarranted risk in light of the circumstances surrounding a specific loan: • Downward trend in sales, profit levels, and margins. • Impaired working capital position. • Cash flow is strained in order to meet debt repayment. • Loan delinquency ( 30 - 60 days) and overdrafts may occur. • Shrinking equity cushion. • Diminishing primary source of repayment and questionable secondary source. • Management abilities are questionable. • Weak industry conditions. • Litigation pending against the borrower. • Collateral or guaranty offers limited protection. • Negative debt service coverage, however the credit is well collateralized and payments are current. 6. SUBSTANDARD – Classified Credit where the borrower’s current net worth, paying capacity, and value of the collateral pledged is inadequate. There is a distinct possibility that we will implement collection procedures if the loan deficiencies are not corrected. In addition, the following characteristics may apply: • Sustained losses have severely eroded the equity and cash flow. • Deteriorating liquidity. • Serious management problems or internal fraud. • Original repayment terms liberalized. • Likelihood of bankruptcy. • Inability to access other funding sources. • Reliance on secondary source of repayment. • Litigation filed against borrower. • Collateral provides little or no value. • Requires excessive attention of the loan officer. • Borrower is uncooperative with loan officer. 7. VULNERABLE – Classified Credit is considered “Substandard” and warrants placing on nonaccrual status. Risk of loss is being evaluated and exit strategy options are under review. Other characteristics that may apply: • Insufficient cash flow to service debt. • Minimal or no payments being received. • Limited options available to avoid the collection process. • Transition status, expect action will take place to collect loan without immediate progress being made. 8. DOUBTFUL – Workout Credit has all the weaknesses inherent in a “Substandard” loan with the added characteristic that collection and/or liquidation is pending. The possibility of a loss is extremely high, but its classification as a loss is deferred until liquidation procedures are completed, or reasonably estimable. Other characteristics that may apply: • Normal operations are severely diminished or have ceased. • Seriously impaired cash flow. • Original repayment terms materially altered. • Secondary source of repayment is inadequate. • Survivability as a “going concern” is impossible. • Collection process has begun. • Bankruptcy petition has been filed. • Judgments have been filed. • Portion of the loan balance has been charged-off .
Impaired Loans	Loans may be classified as impaired if they meet one or more of the following criteria: 1. There has been a charge-off of its principal balance (in whole or in part); 2. The loan has been classified as a TDR ; or 3. The loan is in nonaccrual status. Impairment is measured on a loan-by-loan basis for commercial and agricultural loans by comparing the loan’s outstanding balance to 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 the collateral, less cost to sell, if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Impairment is measured on a loan-by-loan basis for residential real estate and consumer loans by comparing the loan’s unpaid principal balance to the present value of expected future cash flows discounted at the loan’s effective interest rate. We do not recognize interest income on impaired loans in nonaccrual status. For impaired loans not classified as nonaccrual , interest income is recognized daily, as earned, according to the terms of the loan agreement and the principal amount outstanding.
Troubled Debt Restructurings	Loan modifications are considered to be TDRs when the modification includes terms outside of normal lending practices to a borrower who is experiencing financial difficulties. Typical concessions granted include, but are not limited to: • Agreeing to interest rates below prevailing market rates for debt with similar risk characteristics. • Extending the amortization period beyond typical lending guidelines for loans with similar risk characteristics. • Forgiving principal. • Forgiving accrued interest. To determine if a borrower is experiencing financial difficulties, factors we consider include: • The borrower is currently in default on any of their debt. • The borrower would likely default on any of their debt if the concession was not granted. • The borrower’s cash flow was insufficient to service all of their debt if the concession was not granted. • The borrower has declared, or is in the process of declaring, bankruptcy. • The borrower is unlikely to continue as a going concern (if the entity is a business).
Derivative Instruments	The interest rate swaps, associated with our variable rate borrowings, are designated upon inception as cash flow hedges of forecasted interest payments. We enter into LIBOR-based interest rate swaps that involve the receipt of variable amounts in exchange for fixed rate payments, in effect converting variable rate debt to fixed rate debt. Cash flow hedges are assessed for effectiveness using regression analysis. The effective portion of changes in fair value are recorded in OCI and subsequently reclassified into interest expense in the same period in which the related interest on the variable rate borrowings affects earnings. In the event that a portion of the changes in fair value were determined to be ineffective, the ineffective amount would be recorded in earnings.
