| 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 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 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 are 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 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. 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 below 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 September 30, 2016 Commercial Agricultural Residential Real Estate Consumer Unallocated Total July 1, 2016 $ 2,119 $ 534 $ 3,130 $ 541 $ 1,276 $ 7,600 Charge-offs — — (57 ) (74 ) — (131 ) Recoveries 118 — 153 43 — 314 Provision for loan losses (367 ) 612 (452 ) 94 130 17 September 30, 2016 $ 1,870 $ 1,146 $ 2,774 $ 604 $ 1,406 $ 7,800 Allowance for Loan Losses Nine Months Ended September 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 ) — (426 ) (206 ) — (680 ) Recoveries 396 92 248 159 — 895 Provision for loan losses (649 ) 725 (378 ) 129 358 185 September 30, 2016 $ 1,870 $ 1,146 $ 2,774 $ 604 $ 1,406 $ 7,800 Allowance for Loan Losses and Recorded Investment in Loans September 30, 2016 Commercial Agricultural Residential Real Estate Consumer Unallocated Total ALLL Individually evaluated for impairment $ 804 $ 16 $ 1,703 $ — $ — $ 2,523 Collectively evaluated for impairment 1,066 1,130 1,071 604 1,406 5,277 Total $ 1,870 $ 1,146 $ 2,774 $ 604 $ 1,406 $ 7,800 Loans Individually evaluated for impairment $ 7,719 $ 4,520 $ 8,792 $ 29 $ 21,060 Collectively evaluated for impairment 547,128 129,117 251,330 40,731 968,306 Total $ 554,847 $ 133,637 $ 260,122 $ 40,760 $ 989,366 Allowance for Loan Losses Three Months Ended September 30, 2015 Commercial Agricultural Residential Real Estate Consumer Unallocated Total July 1, 2015 $ 3,482 $ 363 $ 3,512 $ 591 $ 1,052 $ 9,000 Charge-offs (61 ) — (70 ) (79 ) — (210 ) Recoveries 68 — 33 47 — 148 Provision for loan losses (500 ) 15 (163 ) (50 ) (40 ) (738 ) September 30, 2015 $ 2,989 $ 378 $ 3,312 $ 509 $ 1,012 $ 8,200 Allowance for Loan Losses Nine Months Ended September 30, 2015 Commercial Agricultural Residential Real Estate Consumer Unallocated Total January 1, 2015 $ 3,821 $ 216 $ 4,235 $ 645 $ 1,183 $ 10,100 Charge-offs (89 ) — (325 ) (252 ) — (666 ) Recoveries 387 72 152 154 — 765 Provision for loan losses (1,130 ) 90 (750 ) (38 ) (171 ) (1,999 ) September 30, 2015 $ 2,989 $ 378 $ 3,312 $ 509 $ 1,012 $ 8,200 Allowance for Loan Losses and Recorded Investment in Loans December 31, 2015 Commercial Agricultural Residential Real Estate Consumer Unallocated Total ALLL Individually evaluated for impairment $ 829 $ 2 $ 1,989 $ — $ — $ 2,820 Collectively evaluated for impairment 1,342 327 1,341 522 1,048 4,580 Total $ 2,171 $ 329 $ 3,330 $ 522 $ 1,048 $ 7,400 Loans Individually evaluated for impairment $ 7,969 $ 4,068 $ 10,266 $ 35 $ 22,338 Collectively evaluated for impairment 440,412 111,843 241,235 34,664 828,154 Total $ 448,381 $ 115,911 $ 251,501 $ 34,699 $ 850,492 The following table displays the credit quality indicators for commercial and agricultural credit exposures based on internally assigned credit risk ratings as of: September 30, 2016 Commercial Agricultural Real Estate Other Advances to Mortgage Brokers Total Real Estate Other Total Total Rating 1 - Excellent $ — $ 529 $ — $ 529 $ — $ — $ — $ 529 2 - High quality 8,819 10,193 27,832 46,844 3,828 1,562 5,390 52,234 3 - High satisfactory 107,613 37,839 — 145,452 23,612 11,557 35,169 180,621 4 - Low satisfactory 275,806 73,465 — 349,271 50,083 25,066 75,149 424,420 5 - Special mention 4,448 733 — 5,181 6,483 6,810 13,293 18,474 6 - Substandard 6,037 1,527 — 7,564 3,126 1,510 4,636 12,200 7 - Vulnerable 6 — — 6 — — — 6 8 - Doubtful — — — — — — — — Total $ 402,729 $ 124,286 $ 27,832 $ 554,847 $ 87,132 $ 46,505 $ 133,637 $ 688,484 December 31, 2015 Commercial Agricultural Real Estate Other Advances to Mortgage Brokers Total Real Estate Other Total Total Rating 1 - Excellent $ — $ 499 $ — $ 499 $ — $ — $ — $ 499 2 - High quality 7,397 11,263 — 18,660 4,647 2,150 6,797 25,457 3 - High satisfactory 99,136 29,286 — 128,422 28,886 13,039 41,925 170,347 4 - Low satisfactory 222,431 62,987 — 285,418 37,279 22,166 59,445 344,863 5 - Special mention 4,501 473 — 4,974 3,961 1,875 5,836 10,810 6 - Substandard 9,941 256 — 10,197 1,623 139 1,762 11,959 7 - Vulnerable 211 — — 211 146 — 146 357 8 - Doubtful — — — — — — — — Total $ 343,617 $ 104,764 $ — $ 448,381 $ 76,542 $ 39,369 $ 115,911 $ 564,292 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: 1. Agreeing to interest rates below prevailing market rates for debt with similar risk characteristics. 2. Extending the amortization period beyond typical lending guidelines for loans with similar risk characteristics. 3. Forgiving principal. 4. Forgiving accrued interest. To determine if a borrower is experiencing financial difficulties, factors we consider include: 1. The borrower is currently in default on any of their debt. 2. The borrower would likely default on any of their debt if the concession was not granted. 3.
