SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Mar. 31, 2021
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The unaudited condensed consolidated financial statements of Mackinac Financial Corporation (the “Corporation”) have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three month period ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The unaudited consolidated financial statements and footnotes thereto should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2020. In order to properly reflect some categories of other income and other expenses, reclassifications of expense and income items have been made to prior period numbers. The “net” other income and other expenses were unchanged by these reclassifications. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of investment securities, the valuation of foreclosed real estate, deferred tax assets, mortgage servicing rights, the assessment of goodwill for impairment, and the fair value of assets and liabilities acquired in business combinations. Acquired Loans Loans acquired with evidence of credit deterioration since inception and for which it is probable that all contractual payments will not be received are accounted for under ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310-30”). These loans are recorded at fair value at the time of acquisition, with no carryover of the related allowance for loan losses. Fair value of acquired loans is determined using a discounted cash flow methodology based on assumptions about the amount and timing of principal and interest payments, principal prepayments and principal defaults and losses, and current market rates. In recording the fair values of acquired impaired loans at acquisition date, management calculates a non-accretable difference (the credit component of the purchased loans) and an accretable difference (the yield component of the purchased loans). Over the life of the acquired loans, management continues to estimate cash flows expected to be collected. We evaluate at each balance sheet date whether it is probable that we will be unable to collect all cash flows expected at acquisition and if so, recognize a provision for loan loss in our consolidated statement of operations. For any significant increases in cash flows expected to be collected, we adjust the amount of the accretable yield recognized on a prospective basis over the pool’s remaining life. Performing acquired loans are accounted for under Financial Accounting Standards Board (“FASB”) Topic 310-20, Receivables – Nonrefundable Fees and Other Costs. Performance of certain loans may be monitored and based on management’s assessment of the cash flows and other facts available, portions of the accretable difference may be delayed or suspended if management deems appropriate. The Corporation’s policy for determining when to discontinue accruing interest on performing acquired loans and the subsequent accounting for such loans is essentially the same as the policy for originated loans. Allowance for Loan Losses The allowance for loan losses includes specific allowances related to loans, when they have been judged to be impaired. A loan is impaired when, based on current information, it is probable that the Corporation will not collect all amounts due in accordance with the contractual terms of the loan agreement. These specific allowances are based on discounted cash flows of expected future payments using the loan’s initial effective interest rate or the fair value of the collateral if the loan is collateral dependent. The Corporation also has an unallocated allowance for loan losses for loans not considered impaired. The allowance for loan losses is maintained at a level which management believes is adequate to provide for probable loan losses. Management periodically evaluates the adequacy of the allowance using the Corporation’s past loan loss experience, known and inherent risks in the portfolio, composition of the portfolio, current economic conditions, and other factors. The allowance does not include the effects of expected losses related to future events or future changes in economic conditions. This evaluation is inherently subjective since it requires material estimates that may be susceptible to significant change. Loans are charged against the allowance for loan losses when management believes the collectability of the principal is unlikely. In addition, various regulatory agencies periodically review the allowance for loan losses. These agencies may require additions to the allowance for loan losses based on their judgments of collectability. In management’s opinion, the allowance for loan losses is adequate to cover probable losses relating to specifically identified loans, as well as probable losses inherent in the balance of the loan portfolio as of the balance sheet date. Stock Compensation Plans On May 22, 2012, the Corporation’s shareholders approved the Mackinac Financial Corporation 2012 Incentive Compensation Plan, under which current and prospective employees, non-employee directors and consultants may be awarded incentive stock options, non-statutory stock options, shares of restricted stock awards (“RSAs”), stock grants, or stock appreciation rights. The aggregate number of shares of the Corporation’s common stock issuable under the plan is 575,000. At March 31, 2021 there were 6,560 shares available for issuance under this plan. Awards are made to executive officers at the discretion of the compensation committee of the board of directors. Awards are made to certain other senior officers at the discretion of the Corporation’s management. Compensation cost equal to the fair value of the award is recognized over the vesting period.

RECENT ACCOUNTING PRONOUNCEMENTS
RECENT ACCOUNTING PRONOUNCEMENTS	2. RECENT ACCOUNTING PRONOUNCEMENTS ASU 2016-13 requires an entity to measure expected credit losses for financial assets over the estimated lifetime of expected credit loss and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The standard includes the following core concepts in determining the expected credit loss. The estimate must: (a) be based on an asset’s amortized cost (including premiums or discounts, net deferred fees and costs, foreign exchange and fair value hedge accounting adjustments), (b) reflect losses expected over the remaining contractual life of an asset (considering the effect of voluntary prepayments), (c) consider available relevant information about the estimated collectability of cash flows (including information about past events, current conditions, and reasonable and supportable forecasts), and (d) reflect the risk of loss, even when that risk is remote. ASU 2016-13 also amends the recording of purchased credit-deteriorated assets. Under the new guidance, an allowance will be recognized at acquisition through a gross-up approach whereby an entity will record as the initial amortized cost the sum of (a) the purchase price and (b) an estimate of credit losses as of the date of acquisition. In addition, the guidance also requires immediate recognition in earnings of any subsequent changes, both favorable and unfavorable, in expected cash flows by adjusting this allowance. ASU 2016-13 also amends the impairment model for available-for-sale debt securities and requires entities to determine whether all or a portion of the unrealized loss on an available-for-sale debt security is a credit loss. Management may not use the length of time a security has been in an unrealized loss position as a factor in concluding whether a credit loss exists, as is currently permitted. In addition, an entity will recognize an allowance for credit losses on available-for-sale debt securities as a contra-account to the amortized cost basis rather than as a direct reduction of the amortized cost basis of the investment, as is currently required. As a result, entities will recognize improvements to credit losses on available-for-sale debt securities immediately in earnings rather than as interest income over time under current practice. New disclosures required by ASU 2016-13 include: (a) for financial assets measured at amortized cost, an entity will be required to disclose information about how it developed its allowance, including changes in the factors that influenced management’s estimate of expected credit losses and the reasons for those changes, (b) for financial receivables and net investments in leases measured at amortized cost, an entity will be required to further disaggregate the information it currently discloses about the credit quality of these assets by year or the asset’s origination or vintage for as many as five annual periods, and (c) for available-for-sale debt securities, an entity will be required to provide a roll-forward of the allowance for credit losses and an aging analysis for securities that are past due. Upon adoption of ASU 2016-13, a cumulative-effect adjustment to retained earnings will be recorded as of the beginning of the first reporting period in which the guidance is effective. The Corporation is currently evaluating the provisions of ASU 2016-13 to determine the potential impact on the Corporation's consolidated financial condition and results of operations. The Corporation has formed a cross-functional implementation team consisting of individuals from finance, credit and information systems. A project plan and timeline has been developed and the implementation team meets regularly to assess the project status to ensure adherence to the timeline. The implementation team has also been working with a software vendor to assist in implementing required changes to credit loss estimation models and proceses, and is finalizing the historical data collected to be utilized in the credit loss models. The Corporation expects to recognize a cumulative effect adjustment to the opening balance of retained earnings as of the beginning of the first reporting period in which ASU 2016-13 is effective. The Corporation has not yet determined the magnitude of any such one-time adjustment or the potential impact of ASU 2016-13 on its condensed consolidated financial statements. In October 2019 the Financial Accounting Standards Board (FASB) voted to defer the effective date of ASU 2016-13 to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, for smaller reporting companies (as defined by the Securities Exchange Commission).

Through the loan review process, ratings are modified as believed to be appropriate to reflect changes in the credit. Our ability to manage credit risk depends in large part on our ability to properly identify and manage problem loans. To do so, we operate a credit risk rating system under which our credit management personnel assign a credit risk rating to each loan at the time of origination and review loans on a regular basis to determine each loan’s credit risk rating on a scale of 1 through 8, with higher scores indicating higher risk. The credit risk rating structure used is shown below. In the context of the credit risk rating structure, the term Classified is defined as a problem loan which may or may not be in a nonaccrual status, dependent upon current payment status and collectability. Strong (1) Borrower is not vulnerable to sudden economic or technological changes. They have “strong” balance sheets and are within an industry that is very typical for our markets or type of lending culture. Borrowers also have “strong” financial and cash flow performance and excellent collateral (low loan to value or readily available to liquidate collateral) in conjunction with an impeccable repayment history. Good (2) Borrower shows limited vulnerability to sudden economic change. These borrowers have “above average” financial and cash flow performance and a very good repayment history. The balance sheet of the company is also very good as compared to peer and the company is in an industry that is familiar to our markets or our type of lending. The collateral securing the deal is also very good in terms of its type, loan to value, and other relevant characteristics. Average (3) Borrower is typically a well-seasoned business, however may be susceptible to unfavorable changes in the economy, and could be somewhat affected by seasonal factors. The borrowers within this category exhibit financial and cash flow performance that appear “average” to “slightly above average” when compared to peer standards and they show an adequate payment history. Collateral securing this type of credit is good, exhibiting above average loan to values, and other relevant characteristics. Acceptable (4) A borrower within this category exhibits financial and cash flow performance that appear adequate and satisfactory when compared to peer standards and they show a satisfactory payment history. The collateral securing the request is within supervisory limits and overall is acceptable. Borrowers rated acceptable could also be newer businesses that are typically susceptible to unfavorable changes in the economy, and more than likely could be affected by seasonal factors. Acceptable Watch (44) The borrower may have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Acceptable Watch assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. Examples of this type of credit include a start-up company fully based on projections, a documentation issue that needs to be corrected or a general market condition that the borrower is working through to get corrected. Substandard (6) Substandard loans are classified assets exhibiting a number of well-defined weaknesses that jeopardize normal repayment. The assets are no longer adequately protected due to declining net worth, lack of earning capacity, or insufficient collateral offering the distinct possibility of the loss of a portion of the loan principal. Loans classified as substandard clearly represent troubled and deteriorating credit situations requiring constant supervision. Doubtful (7) Loans in this category exhibit the same, if not more pronounced weaknesses used to describe the substandard credit. Loans are frozen with collection improbable. Such loans are not yet rated as Charge-off because certain actions may yet occur which would salvage the loan. Charge-off/Loss (8) Loans in this category are largely uncollectible and should be charged against the loan loss reserve immediately. General Reserves: For loans with a credit risk rating of 44 or better and any loans with a risk rating of 6 or 7 not considered impaired, reserves are established based on the type of loan collateral, if any, and the assigned credit risk rating. Determination of the allowance is inherently subjective as it requires significant estimates, including the amounts and timing of expected future cash flows on impaired loans, estimated losses on pools of homogenous loans based on historical loss experience, and consideration of current environmental factors and economic trends, all of which may be susceptible to significant change. Using a historical average loss by loan type as a base, each loan graded as higher risk is assigned a specific percentage. The residential real estate and consumer loan portfolios are assigned a loss percentage as a homogenous group. If, however, on an individual loan the projected loss based on collateral value and payment histories is in excess of the computed allowance, the allocation is increased for the higher anticipated loss. These computations provide the basis for the allowance for loan losses as recorded by the Corporation.

Loans are considered impaired when, based on current information and events, it is probable the Corporation will be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. Impairment is evaluated in total for smaller-balance loans of a similar nature and on an individual loan basis for other loans. If a loan is impaired, a specific valuation allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged off when deemed uncollectible.

Generally restructurings are related to interest rate reductions, loan term extensions and short term payment forbearance as a means to maximize collectability of troubled credits. If a portion of the TDR loan is uncollectible (including forgiveness of principal), the uncollectible amount will be charged off against the allowance at the time of the restructuring. In general, a borrower must make at least six consecutive timely payments before the Corporation would consider a return of a restructured loan to accruing status in accordance with FDIC guidelines regarding restoration of credits to accrual status. More recent regulatory guidelines and accounting standards indicate that loan modifications or forbearances related to the COVID-19 pandemic will generally not be considered TDRs. The Corporation has, in accordance with generally accepted accounting principles and applicable accounting standard updates, evaluated all loan modifications to determine the fair value impact of the underlying asset. The carrying amount of the loan is compared to the expected payments to be received, discounted at the loan’s original rate, or for collateral dependent loans, to the fair value of the collateral. There were no TDRs that occurred during the three months ended March 31, 2021 and 3 TDRs during the three months ended March 31, 2020. Insider Loans The Bank, in the ordinary course of business, grants loans to the Corporation’s executive officers and directors, including their families and firms in which they are principal owners.

SERVICING RIGHTS	7. SERVICING RIGHTS Mortgage Loans Mortgage servicing rights (“MSRs”) are recorded when loans are sold in the secondary market with servicing retained. As of March 31, 2021, the Corporation had obligations to service approximately $191.363 million of residential first mortgage loans. The valuation of MSRs is based upon the net present value of the projected revenues over the expected life of the loans being serviced, as reduced by estimated internal costs to service these loans. On a quarterly basis, management evaluates the MSRs for impairment. The key economic assumptions used in determining the fair value of the MSRs include an annual constant prepayment speed of 19.01% and a discount rate of 7.75% as of March 31, 2021. The following table summarizes MSRs capitalized and amortized (dollars in thousands) for the three month periods ending March 31, 2021 and March 31, 2020: March 31, March 31, 2021 2020 Balance at beginning of period $ 1,359 $ 1,499 Additions from loans sold with servicing retained 75 — Amortization (38) (35) Balance at end of period $ 1,396 $ 1,464 Balance of loan servicing portfolio $ 191,363 $ 246,370 Mortgage servicing rights as % of portfolio .73% .59% Fair value of servicing rights 1,436 2,159 Commercial Loans The Corporation periodically retains the servicing on certain commercial loans that have been sold. These loans were originated and underwritten under the SBA and USDA government guarantee programs, in which the guaranteed portion of the loan was sold to a third party with servicing retained. The balance of these sold loans with servicing retained at March 31, 2021 was approximately as of March 31, 2020. This valuation was established in consideration of the discounted cash flow of net expected servicing income over the life of the loans.

They are collateralized at March 31, 2021 by the following: a collateral agreement on the Corporation’s one to four family residential real estate loans with a book value of approximately $66.740 million; mortgage related and municipal securities with an amortized cost and estimated fair value of $20.318 million and $20.887 million, respectively; and Federal Home Loan Bank stock owned by the Bank totaling $4.924 million. Prepayment of the advances is subject to the provisions and conditions of the credit policy of the Federal Home Loan Bank of Indianapolis in effect as of March 31, 2021. The Coronavirus Aid, Relief, and Economic Security Act (CARES Act), created the Paycheck Protection Program to support lending to small businesses that have been affected by the disruption caused by COVID-19. The Federal Reserve created the Paycheck Protection Program Lending Facility (PPPLF) to offer a source of liquidity to the financial institution lenders who lend to small businesses through the Small Business Administration’s (SBA) Paycheck Protection Program. The PPPLF bears an interest rate of 0.35% and is collateralized by the PPP loans pledged. There were no PPP loans pledged as of March 31, 2021 as the PPPLF was repaid during the third quarter of 2020. The Corporation currently has one correspondent banking borrowing relationship. As of March 31, 2021 the relationship consisted of a $15.0 million revolving line of credit, which had no balance. The line of credit bears an interest rate of LIBOR plus 2.00%, with a floor rate of 3.00% and a ceiling of 22 %. The line of credit expires April 30, 2022. LIBOR at March 31, 2021 was 0.20 %. This relationship is secured by all of the outstanding mBank stock. The USDA Rural Development borrowing bears an interest rate of 1.00% and matures in August, 2024. It is collateralized by an assignment of a demand deposit account held by the Corporation’s wholly owned subsidiary, First Rural Relending, in the amount of $.389 million, and guaranteed by the Corporation.

DEFINED BENEFIT PENSION PLAN
DEFINED BENEFIT PENSION PLAN	9. DEFINED BENEFIT PENSION PLAN The Corporation acquired the Peninsula Financial Corporation noncontributory defined benefit pension plan in 2014. Effective December 31, 2005, the plan was amended to freeze participation in the plan; therefore, no additional employees are eligible to become participants in the plan. The benefits are based on years of service and the employee’s compensation at the time of retirement. The Plan was amended effective December 31, 2010, to freeze benefit accrual for all participants. Expected contributions to the Plan in 2021 are $57,000. The anticipated distributions over the next five years and through December 31, 2030 are detailed in the table below (dollars in thousands): 2021 $ 133 2022 140 2023 144 2024 142 2025 157 2026-2030 901 Total $ 1,617 The Corporation receives a valuation of the Plan annually. As such, at March 31, 2021, the plan’s assets had a fair value of $2.264 million and the Corporation had a net unfunded liability of $1.370 million. The accumulated benefit obligation at March 31, 2021 was $3.634 million. Assumptions in the actuarial valuation are: 2021 2020 Weighted average discount rate 2.45% 2.45% Rate of increase in future compensation levels N/A N/A Expected long-term rate of return on plan assets 2.00% 2.00% The expected long-term rate of return on plan assets reflects management’s expectations of long-term average rates of return on funds invested to provide for benefits included in the projected benefit obligation. The expected return is based on the outlook for inflation, fixed income returns and equity returns, while also considering historical returns, asset allocation and investment strategy. The discount rate assumption is based on investment yields available on AA rated long-term corporate bonds. The primary investment objective is to maximize growth of the pension plan assets to meet the projected obligations to the beneficiaries over a long period of time, and to do so in a manner that is consistent with the Corporation’s risk tolerance. The intention of the plan sponsor is to invest the plan assets in mutual funds with the following asset allocation; which was in place at both March 31, 2021 and December 31, 2020.

A valuation allowance is provided against deferred tax assets when it is more likely than not that some or all of the deferred tax asset will not be realized. The Corporation, as of March 31, 2021 had a net operating loss carryforwards for tax purposes of approximately $8.0 million. The carryforwards, if not utilized, will begin to expire in the year 2023. A portion of the NOL and credit carryforwards are subject to the limitations for utilization as set forth in Section 382 of the Internal Revenue Code. The annual limitation is $2.0 million for the NOL and the equivalent value of tax credits, which is approximately $.420 million. These limitations for use were established in conjunction with the recapitalization of the Corporation in December 2004. The Corporation will continue to evaluate the future benefits from these carryforwards in order to determine if any adjustment to the deferred tax asset is warranted. The Corporation recognized a federal income tax expense of approximately $.398 million for the three months ended March 31, 2021 and $.811 million for the three months ended March 31, 2020.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended
FAIR VALUE MEASUREMENTS	Mar. 31, 2021
FAIR VALUE
FAIR VALUE	12. FAIR VALUE MEASUREMENTS Fair value estimates, methods, and assumptions are set forth below for the Corporation’s financial instruments. Cash, cash equivalents, and interest-bearing deposits Securities - Fair values are based on quoted market prices where available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals. Federal Home Loan Bank stock – Loans - Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, residential mortgage, and other consumer. The fair value of loans is calculated by discounting scheduled cash flows using discount rates reflecting the credit and interest rate risk inherent in the loan. The methodology in determining fair value of nonaccrual loans is to average them into the blended interest rate at 0 % interest. This has the effect of decreasing the carrying amount below the risk-free rate amount and, therefore, discounts the estimated fair value. Impaired loans are measured at the estimated fair value of the expected future cash flows at the loan’s effective interest rate or the fair value of the collateral for loans which are collateral dependent. Therefore, the carrying values of impaired loans approximate the estimated fair values for these assets. Deposits - The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits and savings, is equal to the amount payable on demand at the reporting date. The fair value of time deposits is based on the discounted value of contractual cash flows applying interest rates currently being offered on similar time deposits. Borrowings - Rates currently available for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt. The fair value of borrowed funds due on demand is the amount payable at the reporting date. Accrued interest Off-balance-sheet instruments - The fair value of commitments is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements, the current interest rates, and the present creditworthiness of the counterparties. Since the differences in the current fees and those reflected to the off-balance-sheet instruments at year-end are immaterial, no amounts for fair value are presented. The following table presents information for financial instruments at March 31, 2021 and December 31, 2020 (dollars in thousands): March 31, 2021 December 31, 2020 Level in Fair Carrying Estimated Carrying Estimated Value Hierarchy Amount Fair Value Amount Fair Value Financial assets: Cash and cash equivalents Level 1 $ 243,492 $ 243,492 $ 218,977 $ 218,977 Interest-bearing deposits Level 2 2,427 2,427 2,917 2,917 Securities available for sale Level 2 108,083 108,083 110,505 110,505 Securities available for sale Level 3 1,331 1,331 1,331 1,331 Federal Home Loan Bank stock Level 2 4,924 4,924 4,924 4,924 Net loans Level 3 1,057,914 1,061,119 1,071,776 1,072,770 Accrued interest receivable Level 3 4,176 4,176 4,310 4,310 Total financial assets $ 1,422,347 $ 1,425,552 $ 1,414,740 $ 1,415,734 Financial liabilities: Deposits Level 2 $ 1,273,279 $ 1,288,686 $ 1,258,776 $ 1,262,930 Borrowings Level 2 53,459 52,427 63,479 61,975 Accrued interest payable Level 3 211 211 453 453 Total financial liabilities $ 1,326,949 $ 1,341,324 $ 1,322,708 $ 1,325,358 Limitations - Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Corporation’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Corporation’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on-and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial assets or liabilities include premises and equipment, other assets, and other liabilities. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates. The following is information about the Corporation’s assets and liabilities measured at fair value on a recurring basis at March 31, 2021, and the valuation techniques used by the Corporation to determine those fair values. Level 1: In general, fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities that the Corporation has the ability to access. Level 2: Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly. These Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3: Level 3 inputs are unobservable inputs, including inputs available in situations where there is little, if any, market activity for the related asset or liability. The fair value of all investment securities at March 31, 2021 and December 31, 2020 were based on level 2 and level 3 inputs. There are no other assets or liabilities measured on a recurring basis at fair value. For additional information regarding investment securities, please refer to “Note 4 - Investment Securities.” The table below shows investment securities measured at fair value on a recurring basis (dollars in thousands): Quoted Prices Significant Significant Total (Gains) in Active Markets Other Observable Unobservable Losses for Balance at for Identical Assets Inputs Inputs Three Months Ended (dollars in thousands) March 31, 2021 (Level 1) (Level 2) (Level 3) March 31, 2021 Assets Corporate $ 29,124 $ — $ 28,624 $ 500 $ — US Treasury 1,070 — 1,070 — — US Agencies 6,564 — 6,564 — — US Agencies - MBS 31,292 — 31,292 — — Obligations of state and political subdivisions 41,364 — 40,533 831 2 $ 109,414 $ 2 Quoted Prices Significant Significant in Active Markets Other Observable Unobservable Total (Gains) Losses for Balance at for Identical Assets Inputs Inputs Twelve Months Ended (dollars in thousands) December 31, 2020 (Level 1) (Level 2) (Level 3) December 31, 2020 Assets Corporate $ 28,043 $ — $ 27,543 $ 500 $ — US Agencies 6,589 — 6,589 — — US Agencies - MBS 34,280 — 34,280 — — Obligations of state and political subdivisions 42,924 — 42,093 831 2 $ 111,836 $ 2 The Corporation had no Level 3 assets or liabilities measured at fair value on a recurring basis as of March 31, 2021, or December 31, 2020 other than as described above. In instances where inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Corporation’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability. The Corporation also has assets that under certain conditions are subject to measurement at fair value on a non-recurring basis. These assets include certain impaired loans and other real estate owned. The Corporation has estimated the fair values of these assets using Level 3 inputs, specifically discounted cash flow projections.

The Corporation estimates the fair value of the loans based on the present value of expected future cash flows using management’s best estimate of key assumptions. These assumptions include future payment ability, timing of payment streams, and estimated realizable values of available collateral (typically based on outside appraisals).

COMMITMENTS, CONTINGENCIES AND CREDIT RISK	14. COMMITMENTS, CONTINGENCIES AND CREDIT RISK Financial Instruments With Off-Balance-Sheet Risk The Corporation is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The Corporation’s exposure to credit loss, in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit, is represented by the contractual amount of those instruments. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. These commitments are as follows (dollars in thousands): March 31, December 31, 2021 2020 Commitments to extend credit: Variable rate $ 121,102 $ 114,458 Fixed rate 53,659 58,175 Standby letters of credit - Variable rate 8,003 8,781 Credit card commitments - Fixed rate 7,569 7,136 $ 190,333 $ 188,550 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Corporation evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Corporation upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, and income-producing commercial properties. Standby letters of credit are conditional commitments issued by the Corporation to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The commitments are structured to allow for 100% collateralization on all standby letters of credit. Credit card commitments are commitments on credit cards issued by the Corporation’s subsidiary and serviced by other companies. These commitments are unsecured. Legal Proceedings and Contingencies In the normal course of business, the Corporation is involved in various legal proceedings. For an expanded discussion on the Corporation’s legal proceedings, see Part II, Item 1, “Legal Proceedings” in this report. C oncentration of Credit Risk The Bank grants commercial, residential, agricultural, and consumer loans throughout Michigan and Northeastern Wisconsin. The Bank’s most prominent concentration in the loan portfolio relates to commercial real estate loans to operators of nonresidential buildings. This concentration at March 31, 2021 represents $137.356 million, or 16.78%, compared to $138.992 million, or 16.95 %, of the commercial loan portfolio on December 31, 2020. The remainder of the commercial loan portfolio is diversified in such categories as hospitality and tourism, real estate agents and managers, new car dealers, gas stations and convenience stores, petroleum, forestry, agriculture and construction. Due to the diversity of the Bank’s locations, the ability of debtors of residential and consumer loans to honor their obligations is not tied to any particular economic sector.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements of Mackinac Financial Corporation (the “Corporation”) have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three month period ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The unaudited consolidated financial statements and footnotes thereto should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2020. In order to properly reflect some categories of other income and other expenses, reclassifications of expense and income items have been made to prior period numbers. The “net” other income and other expenses were unchanged by these reclassifications. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of investment securities, the valuation of foreclosed real estate, deferred tax assets, mortgage servicing rights, the assessment of goodwill for impairment, and the fair value of assets and liabilities acquired in business combinations.
Acquired Loans	Acquired Loans Loans acquired with evidence of credit deterioration since inception and for which it is probable that all contractual payments will not be received are accounted for under ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310-30”). These loans are recorded at fair value at the time of acquisition, with no carryover of the related allowance for loan losses. Fair value of acquired loans is determined using a discounted cash flow methodology based on assumptions about the amount and timing of principal and interest payments, principal prepayments and principal defaults and losses, and current market rates. In recording the fair values of acquired impaired loans at acquisition date, management calculates a non-accretable difference (the credit component of the purchased loans) and an accretable difference (the yield component of the purchased loans). Over the life of the acquired loans, management continues to estimate cash flows expected to be collected. We evaluate at each balance sheet date whether it is probable that we will be unable to collect all cash flows expected at acquisition and if so, recognize a provision for loan loss in our consolidated statement of operations. For any significant increases in cash flows expected to be collected, we adjust the amount of the accretable yield recognized on a prospective basis over the pool’s remaining life. Performing acquired loans are accounted for under Financial Accounting Standards Board (“FASB”) Topic 310-20, Receivables – Nonrefundable Fees and Other Costs. Performance of certain loans may be monitored and based on management’s assessment of the cash flows and other facts available, portions of the accretable difference may be delayed or suspended if management deems appropriate. The Corporation’s policy for determining when to discontinue accruing interest on performing acquired loans and the subsequent accounting for such loans is essentially the same as the policy for originated loans.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses includes specific allowances related to loans, when they have been judged to be impaired. A loan is impaired when, based on current information, it is probable that the Corporation will not collect all amounts due in accordance with the contractual terms of the loan agreement. These specific allowances are based on discounted cash flows of expected future payments using the loan’s initial effective interest rate or the fair value of the collateral if the loan is collateral dependent. The Corporation also has an unallocated allowance for loan losses for loans not considered impaired. The allowance for loan losses is maintained at a level which management believes is adequate to provide for probable loan losses. Management periodically evaluates the adequacy of the allowance using the Corporation’s past loan loss experience, known and inherent risks in the portfolio, composition of the portfolio, current economic conditions, and other factors. The allowance does not include the effects of expected losses related to future events or future changes in economic conditions. This evaluation is inherently subjective since it requires material estimates that may be susceptible to significant change. Loans are charged against the allowance for loan losses when management believes the collectability of the principal is unlikely. In addition, various regulatory agencies periodically review the allowance for loan losses. These agencies may require additions to the allowance for loan losses based on their judgments of collectability. In management’s opinion, the allowance for loan losses is adequate to cover probable losses relating to specifically identified loans, as well as probable losses inherent in the balance of the loan portfolio as of the balance sheet date.
Stock Compensation Plans	Stock Compensation Plans On May 22, 2012, the Corporation’s shareholders approved the Mackinac Financial Corporation 2012 Incentive Compensation Plan, under which current and prospective employees, non-employee directors and consultants may be awarded incentive stock options, non-statutory stock options, shares of restricted stock awards (“RSAs”), stock grants, or stock appreciation rights. The aggregate number of shares of the Corporation’s common stock issuable under the plan is 575,000. At March 31, 2021 there were 6,560 shares available for issuance under this plan. Awards are made to executive officers at the discretion of the compensation committee of the board of directors. Awards are made to certain other senior officers at the discretion of the Corporation’s management. Compensation cost equal to the fair value of the award is recognized over the vesting period.
