LOANS, ALLOWANCE FOR LOAN LOSSES AND IMPAIRED LOANS | LOANS, ALLOWANCE FOR LOAN LOSSES AND IMPAIRED LOANS Portfolio Segments: Residential real estate loans are collateralized by primary and secondary positions on real estate and are underwritten primarily based on borrower's documented income, credit scores, and collateral values. Under consumer home equity loan guidelines, the borrower will be approved for a loan based on a percentage of their home's appraised value less the balance owed on the existing first mortgage. Credit risk is minimized within the residential real estate portfolio as relatively small loan amounts are spread across many individual borrowers. Management evaluates trends in past due loans and current economic factors such as the housing price index on a regular basis. Commercial and agricultural real estate loans are underwritten after evaluating and understanding the borrower's ability to operate profitably and prudently expand its business. Management examines current and projected cash flows to determine the ability of the borrower to repay its obligations as agreed. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally largely dependent on the successful operation of the property or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The level of owner-occupied property versus non-owner-occupied property are tracked and monitored on a regular basis. Agricultural real estate loans are primarily comprised of loans for the purchase of farmland. Loan-to-value ratios on loans secured by farmland generally do not exceed 75% . Consumer non-real estate loans are comprised of originated indirect paper loans secured primarily by boats and recreational vehicles, purchased indirect paper loans secured primarily by household goods and other consumer loans secured primarily by automobiles and other personal assets. Consumer loans underwriting terms often depend on the collateral type, debt to income ratio and the borrower's creditworthiness as evidenced by their credit score. Collateral value alone may not provide an adequate source of repayment of the outstanding loan balance in the event of a consumer non-real estate default. This shortage is a result of the greater likelihood of damage, loss and depreciation for consumer based collateral. Commercial non-real estate loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. These cash flows, however, may not be as expected and the value of collateral securing the loans may fluctuate. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee. Agricultural non-real estate loans are generally comprised of term loans to fund the purchase of equipment, livestock and seasonal operating lines. Operating lines are typically written for one year and secured by the crop and other farm assets as considered necessary. Agricultural loans carry significant credit risks as they may involve larger balances concentrated with single borrowers or groups of related borrowers. In addition, repayment of such loans depends on the successful operation or management of the farm property securing the loan or for which an operating loan is utilized. Farming operations may be affected by adverse weather conditions such as drought, hail or floods that can severely limit crop yields. Credit Quality/Risk Ratings: Management utilizes a numeric risk rating system to identify and quantify the Bank’s risk of loss within its loan portfolio. Ratings are initially assigned prior to funding the loan, and may be changed at any time as circumstances warrant. Ratings range from the highest to lowest quality based on factors that include measurements of ability to pay, collateral type and value, borrower stability and management experience. The Bank’s loan portfolio is presented below in accordance with the risk rating framework that has been commonly adopted by the federal banking agencies. The definitions of the various risk rating categories are as follows: 1 through 4 - Pass. A "Pass" loan means that the condition of the borrower and the performance of the loan is satisfactory or better. 5 - Watch. A "Watch" loan has clearly identifiable developing weaknesses that deserve additional attention from management. Weaknesses that are not corrected or mitigated, may jeopardize the ability of the borrower to repay the loan in the future. 6 - Special Mention. A "Special Mention" loan has one or more potential weakness that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the institution’s credit position in the future. 7 - Substandard. A "Substandard" loan is inadequately protected by the current net worth and paying capacity of the obligor or the collateral pledged, if any. Assets classified as substandard must have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. 8 - Doubtful. A "Doubtful" loan has all the weaknesses inherent in a Substandard loan with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. 9 - Loss. Loans classified as "Loss" are considered uncollectible, and their continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, and a partial recovery may occur in the future.

The ALL represents management’s estimate of probable and inherent credit losses in the Bank’s loan portfolio. Estimating the amount of the ALL requires the exercise of significant judgment and the use of estimates related to the amount and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans based on historical loss experience, and consideration of other qualitative factors such as current economic trends and conditions, all of which may be susceptible to significant change. There are many factors affecting the ALL; some are quantitative, while others require qualitative judgment. The process for determining the ALL (which management believes adequately considers potential factors which result in probable credit losses), includes subjective elements and, therefore, may be susceptible to significant change. To the extent actual outcomes differ from management estimates, additional provision for loan losses could be required that could adversely affect the Company’s earnings or financial position in future periods. Allocations of the ALL may be made for specific loans but the entire ALL is available for any loan that, in management’s judgment, should be charged-off or for which an actual loss is realized. As an integral part of their examination process, various regulatory agencies also review the Bank’s ALL. Such agencies may require that changes in the ALL be recognized when such regulators’ credit evaluations differ from those of our management based on information available to the regulators at the time of their examinations. Changes in the ALL by loan type for the periods presented below were as follows: Residential Real Estate Commercial/Agriculture Real Estate Consumer Non-real Estate Commercial/Agricultural Non-real Estate Unallocated Total Six Months Ended March 31, 2018: Allowance for Loan Losses: Beginning balance, October 1, 2017 $ 1,458 $ 2,523 $ 936 $ 897 $ 128 $ 5,942 Charge-offs (39 ) (1 ) (241 ) — — (281 ) Recoveries 14 — 70 1 — 85 Provision — 105 25 — — 130 Allowance allocation adjustment (123 ) 15 39 (59 ) (178 ) (306 ) Total allowance on originated loans 1,310 2,642 829 839 (50 ) 5,570 Purchased credit impaired loans — — — — — — Other acquired loans: Beginning balance, October 1, 2017 — — — — — — Charge-offs (34 ) (8 ) (20 ) — — (62 ) Recoveries 3 — — — — 3 Provision 35 10 25 — — 70 Allowance allocation adjustment 122 85 79 20 — 306 Total allowance on other acquired loans 126 87 84 20 — 317 Total Allowance on acquired loans 126 87 84 20 — 317 Ending balance, March 31, 2018 $ 1,436 $ 2,729 $ 913 $ 859 $ (50 ) $ 5,887 Allowance for Loan Losses at March 31, 2018: Amount of allowance for loan losses arising from loans individually evaluated for impairment $ 232 $ — $ 38 $ 27 $ — $ 297 Amount of allowance for loan losses arising from loans collectively evaluated for impairment $ 1,204 $ 2,729 $ 875 $ 832 $ (50 ) $ 5,590 Loans Receivable as of March 31, 2018: — Ending balance of originated loans $ 139,412 $ 189,127 $ 111,301 $ 54,205 $ — $ 494,045 Ending balance of purchased credit-impaired loans 169 5,494 327 2,405 — 8,395 Ending balance of other acquired loans 84,364 106,710 3,208 24,406 — 218,688 Ending balance of loans $ 223,945 $ 301,331 $ 114,836 $ 81,016 $ — $ 721,128 Ending balance: individually evaluated for impairment $ 7,925 $ 13,123 $ 1,409 $ 3,577 $ — $ 26,034 Ending balance: collectively evaluated for impairment $ 216,020 $ 288,208 $ 113,427 $ 77,439 $ — $ 695,094 Residential Real Estate Commercial/Agriculture Real Estate Consumer Non-real Estate Commercial/Agricultural Non-real Estate Unallocated Total Six months ended March 31, 2017: Allowance for Loan Losses: Beginning balance, October 1, 2016 $ 2,039 $ 1,883 $ 1,466 $ 652 $ 28 $ 6,068 Charge-offs (110 ) — (239 ) (2 ) — (351 ) Recoveries 4 — 113 1 — 118 Provision — — — — — — Allowance allocation adjustment (226 ) 305 (187 ) 3 105 — Total Allowance on originated loans $ 1,707 $ 2,188 $ 1,153 $ 654 $ 133 $ 5,835 Purchased credit impaired loans — — — — — — Other acquired loans — — — — — — Total Allowance on acquired loans $ — $ — $ — $ — $ — $ — Ending balance, March 31, 2017 $ 1,707 $ 2,188 $ 1,153 $ 654 $ 133 $ 5,835 Allowance for Loan Losses at March 31, 2017: Amount of allowance for loan losses arising from loans individually evaluated for impairment $ 359 $ — $ 59 $ 47 $ — $ 465 Amount of allowance for loan losses arising from loans collectively evaluated for impairment $ 1,348 $ 2,188 $ 1,094 $ 607 $ 133 $ 5,370 Loans Receivable as of March 31, 2017: Ending balance of originated loans $ 143,546 $ 112,016 $ 158,867 $ 30,612 $ — $ 445,041 Ending balance of purchased credit-impaired loans 250 1,832 4 932 — 3,018 Ending balance of other acquired loans 22,049 48,984 497 15,219 — 86,749 Ending balance of loans $ 165,845 $ 162,832 $ 159,368 $ 46,763 $ — $ 534,808 Ending balance: individually evaluated for impairment $ 4,481 $ — $ 631 $ 713 $ — $ 5,825 Ending balance: collectively evaluated for impairment $ 161,364 $ 162,832 $ 158,737 $ 46,050 $ — $ 528,983 The Bank has originated substantially all loans currently recorded on the Company’s accompanying Consolidated Balance Sheet, except as noted below. In February 2016, the Bank selectively purchased loans from Central Bank in Rice Lake and Barron, Wisconsin in the amount of $16,363 . In May 2016, the Bank acquired loans from Community Bank of Northern Wisconsin, headquartered in Rice Lake, Wisconsin totaling $111,740 . In August 2017, the Bank acquired loans from Wells Federal, headquartered in Wells, Minnesota totaling $189,077 . During October 2012, the Bank entered into an agreement to purchase short term consumer loans from a third party on an ongoing basis. As part of the servicer agreement entered into in connection with this purchase agreement, the third party seller agreed to purchase or substitute performing consumer loans for all contracts that become 120 days past due. Pursuant to the ongoing loan purchase agreement, a restricted reserve account was established at 3% of the outstanding consumer loan balances purchased up to a maximum of $1,000 , with such percentage amount of the loans being deposited into a segregated reserve account. The funds in the reserve account are to be released to compensate the Bank for any purchased loans that are not purchased back by the seller or substituted with performing loans and are ultimately charged off by the Bank. During the first quarter of fiscal 2015, the Board of Directors increased the limit of these purchased consumer loans to a maximum of $50,000 . As of September 30, 2017 , new purchases from this third party were terminated. As of March 31, 2018 , the balance of these purchased consumer loans was $ 22,665 compared to $29,555 as of September 30, 2017 . The balance in the cash reserve account at March 31, 2018 was $716 , which is included in Deposits on the accompanying Consolidated Balance Sheet. To date, the Company has not charged off or experienced losses related to the purchased loans. The weighted average rate earned on these purchased consumer loans was 4.19% as of March 31, 2018 .

At September 30, 2017 , the Company identified impaired loans of $24,359 , consisting of $5,851 TDR loan, of which $5,230 are performing TDR loans, $12,035 purchased credit impaired loans, and $6,473 substandard non-TDR loans, which includes $2,387 of non-PCI acquired loans. A loan is identified as impaired when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement. Performing TDRs consist of loans that have been modified and are performing in accordance with the modified terms for a sufficient length of time, generally six months, or loans that were modified on a proactive basis.

Concessions include, but are not limited to, an extension of loan terms, renewals of existing balloon loans, reductions in interest rates and consolidating existing Bank loans at modified terms. A TDR may be either on accrual or nonaccrual status based upon the performance of the borrower and management’s assessment of collectability. If a TDR is placed on nonaccrual status, it remains there until a sufficient period of performance under the restructured terms has occurred at which time it is returned to accrual status. There were 7 delinquent TDRs greater than 60 days past due with a recorded investment of $2,554 at March 31, 2018 , compared to 3 such loans with a recorded investment of $504 at September 30, 2017 .
