Forward Looking Statements
This report contains certain forward looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Rule 175 promulgated thereunder, and Section 21E of the Securities Exchange Act of 1934, as amended and Rule 3b-6 promulgated thereunder. We intend such forward looking statements to be covered by the safe harbor provisions for forward looking statements contained in the Private Securities Litigation Reform Act of 1995, and are included in this statement for purposes of these safe harbor provisions. Forward looking statements, which are based on certain assumptions and describe future plans, strategies and expectations, are generally identifiable by use of the words “believe”, “expect”, “intend”, “anticipate”, “estimate”, “project”, or similar expressions. Our ability to predict results or the actual effect of future plans or strategies is inherently uncertain. Factors which could have a material adverse effect on our operations and future prospects include, but are not limited to, changes in: interest rates, general economic conditions, federal or state tax laws, monetary and fiscal policy, a health crisis, the quality or composition of the loan or investment portfolio, demand for loan products, fluctuation in the value of collateral securing our loan portfolio, deposit flows, competition, cybersecurity risk, demand for financial services in our market area, and accounting principles, policies and guidelines. These risks and uncertainties should be considered in evaluating forward looking statements and undue reliance should not be placed on such statements. Further information concerning our business, including additional factors that could materially affect our consolidated financial results, is included in our filings with the SEC.

Note 2 – Accounting Standards Updates
Pending
ASU No. 2016-13: “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, as amended
In June 2016, ASU No. 2016-13 was issued and updated the measurement for credit losses for AFS debt securities and assets measured at amortized cost which include loans, trade receivables, and any other financial assets with the contractual right to receive cash. Current GAAP requires an “incurred loss” methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. Under the incurred loss approach, entities are limited to a probable initial recognition threshold when credit losses are measured; an entity generally only considers past events and current conditions in measuring the incurred loss.
Under the new guidance, the incurred loss impairment methodology is replaced with a methodology that reflects current expected credit losses (CECL). This methodology requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances which applies to assets measured either collectively or individually.
The update allows an entity to revert to historical loss information that is reflective of the contractual term (considering the effect of prepayments) for periods that are beyond the time frame for which the entity is able to develop reasonable and supportable forecasts. In addition, the disclosures of credit quality indicators in relation to the amortized cost of financing receivables, a current disclosure requirement, are further disaggregated by year of origination (or vintage). The vintage information will be useful for financial statement users to better assess changes in underwriting standards and credit quality trends in asset portfolios over time and the effect of those changes on credit losses.
Overall, the update will allow entities the ability to measure expected credit losses without the restriction of incurred or probable losses that exist under current GAAP. For users of the financial statements, the update requires disclosure of decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The new authoritative guidance was originally effective for interim and annual periods beginning after December 15, 2019. Effective October 16, 2019, the FASB approved and issued changes to the implementation date of this guidance for some filers. As a smaller reporting company, as defined by the SEC, our implementation date was delayed from January 1, 2020 to January 1, 2023. Early adoption continues to be permissible under the revised implementation date. This guidance may have a significant impact on the results of our operations and financial statement disclosures as well as that of the banking industry as a whole.

We have invested a considerable amount of effort toward this guidance and will continue to invest considerable effort until our implementation date. An internal committee was formed and is accountable for timely and accurate adoption of the guidance. A service provider that has focused on the ALLL for more than 10 years and serves hundreds of financial institutions has been engaged to provide us with education, advisory, and software solutions exclusively related to the ACL. We will run parallel processes which will help to ensure we are ready to calculate, review, and report the ACL by the required implementation date.

Expected maturities for government sponsored enterprises and states and political subdivisions may differ from contractual maturities because issuers may have the right to call or prepay obligations.
As the auction rate money market preferred investments have continual call dates, they are not reported by a specific maturity group. Because of their variable monthly payments, mortgage-backed securities and collateralized mortgage obligations are not reported by a specific maturity group.

The following information pertains to AFS securities with gross unrealized losses at September 30, 2021, aggregated by investment category and length of time that individual securities have been in a continuous loss position. There were no AFS securities with gross unrealized losses in a continuous loss position at December 31, 2020.

| Less Than Twelve Months |  | Twelve Months or More |  |
| Gross Unrealized Losses |  | Fair Value |  | Gross Unrealized Losses |  | Fair Value |  | Total Unrealized Losses

Number of securities in an unrealized loss position: |  |  | 37 |  |  |  |  | — |  |  | 37 |

The reduction in unrealized gains on our AFS securities portfolio resulted from the recent increases in intermediate-term and long-term benchmark interest rates.
As of September 30, 2021 and December 31, 2020, we conducted an analysis to determine whether any AFS securities currently in an unrealized loss position should be identified as 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?
Based on our analysis, which included the criteria outlined above and the fact that we have asserted that we do not have to sell any AFS securities in an unrealized loss position, we do not believe that the values of any AFS securities are other-than-temporarily impaired as of September 30, 2021 or December 31, 2020, with the exception of one municipal bond previously identified.

Note 4 – 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, health care, 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 deferred fees or costs. Unless a loan has a nonaccrual status, 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 appropriate amortization method.
The accrual of interest on commercial and agricultural loans, as well as residential real estate loans, is discontinued at the time a loan is 90 days or more past due unless the credit is well-secured and in the process of short-term collection. Upon transferring a loan 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 a charge-off is necessary. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on the contractual term of the loan. In all cases, a loan is placed in nonaccrual status at an earlier date if collection of principal or interest is considered doubtful.
When a loan is placed in nonaccrual status, 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 and achievement of current payment status.
Commercial and agricultural loans include loans for commercial real estate, commercial operating loans, advances to mortgage brokers, farmland and agricultural production, and loans to 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 may be 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, property, or equipment. Government agency guarantee may be required. Personal guarantees and/or life insurance beneficiary assignments are generally required from the owners of closely held corporations, partnerships, and sole proprietorships. In addition, we may 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 pay off 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 consolidated balance sheets. Under the participation agreement, we committed to a maximum outstanding aggregate amount of $80,000. The difference between our outstanding balance 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, our liquidity needs, 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 100% of the lower of the appraised value of the property or the purchase price. Private mortgage insurance is typically required on loans with loan-to-value ratios in excess of 80% unless the loan qualifies for government guarantees.

Table of Contents
Underwriting criteria for originated residential real estate loans generally 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 40% of income.
•Verification of acceptable credit reports.
•Verification of employment, income, and financial information.
Appraisals are performed by independent appraisers and are reviewed for appropriateness. Generally, mortgage loan requests are reviewed by our mortgage loan committee or through a secondary market underwriting system; loans in excess of $1,000 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 15 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. Full or partial loan balances are charged against the ALLL when we believe uncollectability is probable. Subsequent recoveries, if any, are credited to the ALLL.
The ALLL is evaluated on a regular basis for appropriateness. Our periodic review of the collectability of a loan considers 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, or the fair value of the collateral, less costs to sell, if the loan is collateral dependent. 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 related to this portfolio. 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.
While we have experienced fluctuations in credit quality indicators in recent periods, credit quality remained strong at September 30, 2021. The COVID-19 pandemic led to the temporary and some permanent closures of businesses throughout the communities in which we serve, which also led to increased unemployment. We increased the ALLL during 2020 as a result of increased economic and environmental related risk factors, primarily driven by COVID-19. While these risk factors remain, improvement in credit quality indicators resulted in a reduction to the ALLL during the first nine months of 2021.
Summaries of the ALLL and the recorded investment in loans by segments follows:

Table of Contents
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. 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.
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 constitutes 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.
17

Table of Contents
•Shrinking equity cushion.
•Diminishing primary source of repayment and questionable secondary source.
•Management abilities are questionable.
•Weak industry conditions.
•Litigation pending against the borrower.
•Loan may need to be restructured to improve collateral position or reduce payments.
•Collateral or guaranty offers limited protection.
•Negative debt service coverage, however the credit is well collateralized and payments are current.
6. SUBSTANDARD – Classified
Credit is inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged. There is a distinct possibility we will implement collection procedures if the loan deficiencies are not corrected. Any commercial loan placed in nonaccrual status will be rated “7” or worse. 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.
•Interest non-accrual may be warranted.
•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 in 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.

9. LOSS – Charge-off
Credit is considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification is for charged-off loans but does not mean that the asset has absolutely no recovery or salvage value. These loans are further characterized by:
•Liquidation or reorganization under Bankruptcy, with poor prospects of collection.
•Fraudulently overstated assets and/or earnings.
•Collateral has marginal or no value.
•Debtor cannot be located.
•Over 120 days delinquent.

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, or the fair value of the collateral, less costs to sell, if the loan is collateral dependent. Large groups of smaller-balance, homogeneous residential real estate and consumer loans are collectively evaluated for impairment 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
A loan modification is considered to be a TDR 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.
•Agreeing to an interest-only payment structure and delaying principal payments.
•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 debt.
•The borrower would likely default on any debt if the concession is not granted.
•The borrower’s cash flow is insufficient to service all debt if the concession is 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).

We did not restructure any loans by forgiving principal or accrued interest in the three and nine-month periods ended September 30, 2021 or 2020.
Based on our historical loss experience, losses associated with TDRs are not significantly different than other impaired loans within the same loan segment. 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 nine-month periods ended September 30, 2021 and 2020 which were modified within 12 months prior to the default date.

Measures we have taken to assist our customers in connection with the COVID-19 pandemic include loan programs that provide short-term payment relief. Under these programs, borrowers whose loans were in good standing as of March 1, 2020 could elect to defer full or partial payments for a period not to exceed 180 days. Bank regulators issued a statement on March 22, 2020, and a revised statement on April 7, 2020, which provided confirmation that short-term loan modifications made on a good faith basis in response to COVID-19 to borrowers with a current payment status are not categorized as TDRs. Pursuant to this guidance, borrowers granted a short-term loan modification meeting this criteria were not categorized as TDR as of September 30, 2021.

In October, the fixed rate FHLB advance due in 2026 was put by the FHLB, reducing our total FHLB advances to $50,000.
Securities sold under agreements to repurchase are classified as secured borrowings and are reflected at the amount of cash received in connection with the transaction. The securities underlying the agreements have a carrying value and a fair value of $67,542 and $68,773 at September 30, 2021 and December 31, 2020, respectively. Such securities remain under our control. We may be required to provide additional collateral based on the fair value of underlying securities.
Securities sold under repurchase agreements without stated maturity dates, federal funds purchased, and FRB Discount Window advances generally mature within one to four days from the transaction date. We had no federal funds purchased or FRB Discount Window advances during the three and nine-month periods ended September 30, 2021 and 2020.

AFS securities pledged to repurchase agreements are monitored to ensure the appropriate level is collateralized. In the event of maturities, calls, significant principal repayments, or significant decline in market values, we have an adequate level of AFS securities to pledge to satisfy collateral requirements.
As of September 30, 2021, we had the ability to borrow up to an additional $260,815, based on assets pledged as collateral. We had no investment securities that were restricted from being pledged for specific purposes.
On June 2, 2021, we completed a private placement of $30,000 in aggregate principal amount of 3.25% Fixed-to-Floating Rate Subordinated Notes due 2031 (the "Notes"). The Notes will initially bear a fixed interest rate of 3.25% until June 15, 2026, after which time until maturity on June 15, 2031, the interest rate will reset quarterly to an annual floating rate equal to the then-current 3-month SOFR plus 256 basis points. The Notes are redeemable by us at our option, in whole or in part, on or after June 15, 2026. The Notes are not subject to redemption at the option of the holders.

Derivative Instruments
We may use interest rate swaps to manage exposure to interest rate risk and variability in cash flows. The interest rate swap, associated with our variable rate borrowings, was designated upon inception as cash flow hedges of forecasted interest payments. We entered into a LIBOR-based interest rate swap that involves 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 table provides information on derivatives related to variable rate borrowings as of December 31, 2020. There were no derivatives related to variable rate borrowings as of September 30, 2021 as the interest rate swap related to borrowings matured during the second quarter of 2021.

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 the use of counterparty limits.
Note 6 – Computation of Earnings Per Common 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 includes 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 and grant awards under the RSP.
Earnings per common share have been computed based on the following for the:

| Three Months Ended September 30 |  | Nine Months Ended September 30
| 2021 |  | 2020 |  | 2021 |  | 2020
Average number of common shares outstanding for basic calculation | 7,932,227 |  |  | 7,966,811 |  |  | 7,948,578 |  |  | 7,945,762 |

Note 7 – Restricted Stock Plan
We adopted the RSP, an equity-based bonus plan, in 2020. Under the RSP, we may award restricted stock bonuses to eligible employees on an annual basis that are not fully transferable or vested until certain conditions are met. Currently, the eligible employees are the Corporation's President and CEO, CFO and the Bank's President. The RSP authorizes the issuance of unvested restricted stock to an eligible employee with a maximum award ranging from 25% to 40% of the employee’s annual salary, on a calendar year basis. The employee must also satisfy the annual performance targets and measures established by the Board of Directors. If these grant conditions are not satisfied, then the award of restricted shares will lapse or be adjusted appropriately, at the discretion of the Board of Directors. All Grant Agreements contain vesting conditions and clawback provisions.
A summary of changes in nonvested restricted stock awards is as follows for the:

| Three Months Ended September 30, 2021
| Number of Shares |  | Fair Value

Note 11 – Fair Value
Under fair value measurement and disclosure authoritative guidance, we group assets and liabilities measured at fair value into three levels, based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine fair value, based on the prioritization of inputs in the valuation techniques. These levels are:

Level 1: | Valuation is based upon quoted prices for identical instruments traded in active markets.
Level 2: | Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market.
Level 3: | Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. Transfers between measurement levels are recognized at the end of reporting periods.
Fair value measurement requires the use of an exit price notion which may differ from entrance pricing. Generally we believe our assets and liabilities classified as Level 1 or Level 2 approximate an exit price notion.
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.
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.
Loans: We do not record loans at fair value on a recurring basis. However, some 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, or the fair value of the collateral, less costs 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:

| September 30, 2021
Valuation Technique | Fair Value | Unobservable Input |  | Actual Range |  | Weighted Average
|  | Discount applied to collateral: |  |  |  |
|  | Real Estate |  | 20% - 30% |  | 23%
|  | Equipment |  | 20% - 35% |  | 28%
Discounted value | $22,848 | Cash crop inventory |  | 40% |  | 40%
|  | Livestock |  | 30% |  | 30%
|  | Accounts receivable |  | 50% |  | 50%
|  | Liquor license |  | 75% |  | 75%

| December 31, 2020
Valuation Technique | Fair Value | Unobservable Input |  | Actual Range |  | Weighted Average
|  | Discount applied to collateral: |  |  |  |
|  | Real Estate |  | 20% - 30% |  | 23%
|  | Equipment |  | 20% - 50% |  | 32%
Discounted value | $19,540 | Cash crop inventory |  | 40% |  | 40%
|  | Livestock |  | 30% |  | 30%
|  | Other inventory |  | 50% |  | 50%
|  | Accounts receivable |  | 25% - 50% |  | 27%
|  | Liquor license |  | 75% |  | 75%

Collateral discount rates may have ranges to accommodate differences in the age of the independent appraisal, broker price opinion, or internal evaluation.
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.
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.
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.

Note 14 – Subsequent Events
On September 1, 2021, we announced the commencement of a “modified Dutch Auction” tender offer to purchase up to $20,000 in value of our common stock, or such lesser number of shares of our common stock as are properly tendered and not properly withdrawn, at a price not less than $23.00 nor greater than $27.00 per share. The tender offer expired on October 13, 2021 and resulted in the purchase of 396,576.78534 shares at a price of $27.00 per share for a total amount of approximately $10,708.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.
ISABELLA BANK CORPORATION FINANCIAL REVIEW
(Dollars in thousands except per share amounts)
The following is management's discussion and analysis of our financial condition and results of operations for the unaudited three and nine-month periods ended September 30, 2021 and 2020. This analysis should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020 and with the unaudited interim condensed consolidated financial statements and notes, beginning on page 4 of this report.
Executive Summary
During the three and nine months ended September 30, 2021, we reported net income of $4,686 and $14,705 and earnings per common share of $0.59 and $1.85, respectively. Net income and earnings per common share for the same periods of 2020 were $4,357 and $11,608 and $0.55 and $1.46, respectively. Net interest income increased by $2,424 for the nine-month period ended September 30, 2021 in comparison to the same period in 2020. While we had a reduction in gross interest income for the first nine months of 2021, SBA PPP loan fees helped offset that reduction. Developments leading to the decline included the lowering in interest rates, and a temporary pause in advances to mortgage brokers, resulting in a decrease in interest income of $2,698 for the first nine months of 2021 compared to the same period in 2020. Conversely, we benefited from lower interest rates and a reduction in higher-cost borrowings as interest expense on deposits and borrowings decreased $5,122 for the nine-month period ended September 30, 2021 compared to the same period in 2020.
The provision for loan losses decreased by $2,008 for the nine-month period ended September 30, 2021 compared to the same period in 2020. During 2020, increased economic and environmental risk factors, predominantly driven by COVID-19, drove a significant increase in the provision. While these risk factors remain, credit quality has been strong during 2021. As of September 30, 2021, total past due and nonaccrual loans were $3,498, or 0.28% of gross loans. Additionally, during the first nine months of 2021, net loan charge-offs were low at $52. Strong credit quality, coupled with improvement in economic factors, such as unemployment rates, resulted in a reduction in the ALLL and a provision reversal during the first nine months of 2021.
Noninterest income decreased $90 during the first nine months of 2021 compared to the same period in 2020. While service charges and fees, a component of noninterest income, increased $800 when comparing results for the first nine months of 2021 as compared to the same period in 2020, 2020 also included an additional $723 related to gains from redemption of corporate owned life insurance policies. Noninterest expenses for the first nine months of 2021 declined $98 in comparison to the same period in 2020 and is a direct result of disciplined operating expense control.
As of September 30, 2021, total assets and assets under management were $2,082,701 and $2,859,877, respectively. Assets under management include loans sold and serviced of $285,392 and investment and trust assets managed by Isabella Wealth of $491,784, in addition to assets on our consolidated balance sheet. Loans outstanding as of September 30, 2021 totaled $1,248,558. Since December 31, 2020, PPP loans declined by $20,350 related to PPP loan forgiveness while residential mortgage loans increased $14,077, contributing to a net increase in gross loans of $10,247. Our securities portfolio increased $155,156 since December 31, 2020, predominantly due to purchases of treasury securities. Total deposits were $1,692,316 as of September 30, 2021, which was an increase of $125,999 since December 31, 2020. Increases in demand and savings deposits, largely as a result of SBA PPP and government stimulus funds, were the main drivers of the increase in deposits. All regulatory capital ratios for the Bank exceeded the minimum thresholds to be considered a “well capitalized” institution.
Our net yield on interest earning assets (FTE) was 2.85% and 2.87% for the three and nine months ended September 30, 2021, as compared to 2.89% and 2.93% for the three and nine months ended September 30, 2020. Management implemented strategic programs focused on improving our net yield on interest earning assets, which includes enhanced pricing related to loans and a reduced reliance on higher-cost borrowed funds and brokered deposits as funding sources. While these efforts have helped, the current interest rate environment plus the elevated cash position has had a negative impact on the yield of interest earning assets and future improvements may be gradual. We are committed to increasing earnings and shareholder value through growth in our loan portfolio while maintaining strong underwriting standards, growth in our wealth management services, managing operating costs and increasing our market share within our geographical footprint.

Recent Events and Legislation
Impact of COVID-19: Unexpected and unprecedented changes have occurred during 2020 and into 2021 as the result of COVID-19. The World Health Organization has declared the situation a global pandemic. The pandemic created significant market volatility, economic uncertainty, and disruption to normal business operations around the world, with slowdowns and shutdowns affecting entire industries.
The CARES Act, an unprecedented federal government support program, was enacted on March 27, 2020 in response to the COVID-19 pandemic. It is a $2 trillion stimulus package intended to provide financial relief across the country. The CARES Act included the PPP, which enabled businesses to obtain a forgivable SBA loan to meet payroll, rent, utility, and mortgage interest obligations for the 24-week period following the loan origination, and re-open quickly once the public health crisis ends. The first applications for PPP funds, with a term of two years, were accepted beginning on April 3, 2020. During 2020, we facilitated more than 950 SBA PPP loans for a total of $99,459 and had the opportunity to continue providing funding in 2021 under an additional government stimulus program. During the 2021, we funded 845 SBA PPP loans for a total of $54,551 under this additional government stimulus program. Bank regulators issued an interim rule that neutralizes the regulatory capital effects by allowing a zero percent risk weight, for capital purposes, to loans originated under the PPP. The capital rule was issued April 9, 2020, with an immediate effective date.
Since 2020, many customers have expressed their general concern about the uncertain economic conditions, but it is still premature to reasonably predict the magnitude of the impact. One measure we deployed to assist our customers included changes to service charges and fees on deposit accounts. Since the COVID-19 pandemic led to an increase in the need for electronic services and products, we elected to remove select deposit account charges and fees and temporarily waive others to ease the financial stress on our customers. Other measures we have taken to assist our customers include loan programs that provide short-term payment relief. Under these programs, borrowers whose loans were in good standing as of March 1, 2020 could elect to defer full or partial payments for a period not to exceed 180 days. Loan payment deferrals totaled $306,103, or 23.8% of gross loans, as of June 30, 2020. As of September 30, 2020, active loan payment deferrals declined to $103,858, or 8.0% of gross loans, as the majority of borrowers granted loan payment deferrals had reverted back to contractual payments. As of December 31, 2020, active loan payment deferrals declined even further and totaled $6,048, or 0.5% of gross loans. As of September 30, 2021, we had active loan payment deferrals totaling $20,291, or 1.6% of gross loans.
Bank regulators issued a statement on March 22, 2020, and a revised statement on April 7, 2020, which provided confirmation that short-term loan modifications made on a good faith basis in response to COVID-19 to borrowers with a current payment status are not categorized as TDRs. Pursuant to this guidance, short-term loan modifications meeting this criteria were not categorized as TDR as of September 30, 2021. These programs, along with the SBA PPP, could mask or delay the detection or reporting of deterioration in credit quality indicators.
In response to the COVID-19 pandemic, we temporarily closed branch lobbies, modified staffing levels, and enabled employees to work remotely during most of 2020 and into 2021. While branch operations and staffing levels have generally resumed to normal, the extent to which COVID-19 impacts our business will depend on future developments, which remain highly uncertain and cannot be predicted with any accuracy. We expect the significance of the pandemic, including the extent of its effect on our financial and operational results, to be dictated by, among other factors, its duration, the success of efforts to contain the virus and variants to the virus and the impact of actions taken in response, including the distribution of effective vaccines and success in vaccination rates. Uncertainty created by the pandemic is pervasive, and continues to impact our operations, customers, and various areas of risk. We continue to closely monitor external events and are in continual discussion with our customers to assess, prepare and respond to conditions as they evolve.
Subordinated Debt Issuance: On June 2, 2021, we completed a private placement of $30,000 in aggregate principal amount of 3.25% Fixed-to-Floating Rate Subordinated Notes due 2031 (the “Notes”) to various institutional investors (the “Offering”). The price for the Notes was 100% of the principal amount of the Notes. The Notes are intended to qualify as Tier 2 capital for regulatory purposes. We intend to utilize the net proceeds from the Offering for general corporate purposes, including potential repurchases of common stock and/or merger and acquisition activity. The Notes will initially bear a fixed interest rate of 3.25% until June 15, 2026, after which time until maturity on June 15, 2031, the interest rate will reset quarterly to an annual floating rate equal to the then-current 3-month SOFR plus 256 basis points. The Notes are redeemable by us at our option, in whole or in part, on or after June 15, 2026. Any such redemption will be at a redemption price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest. The Notes are not subject to redemption at the option of the holders.

Net interest income is the amount by which interest income on earning assets exceeds the interest expense on interest bearing liabilities. Net interest income is influenced by changes in the balance and mix of assets and liabilities, as well as market interest rates. While we exert some control over these factors, FRB monetary policy and competition have a significant impact. For analytical purposes, net interest income is adjusted to an FTE basis by including the income tax savings from interest on tax exempt loans and nontaxable investment securities, thus making year to year comparisons more meaningful.

Table of Contents
Volume and Rate Variance Analysis
The following table sets forth the effect of volume and rate changes on interest income and expense for the periods indicated. Changes in interest due to volume and rate were determined as follows:
Volume—change in volume multiplied by the previous period's rate.
Rate—change in the FTE rate multiplied by the previous period's volume.
The change in interest due to both volume and rate has been allocated to volume and rate changes in proportion to the relationship of the absolute dollar amounts of the change in each.

The continuing low interest rate environment continues to place pressure on our net interest margin. SBA PPP fee income has been the primary driver of recent increases in our net yield on interest earning assets. Given the uncertainty in rates and the economic environment as a result of COVID-19, improvement in our net yield on interest earning assets could be gradual.

Allowance for Loan and Lease Losses
The viability of any financial institution is ultimately determined by its management of credit risk. Loans represent our single largest concentration of risk. The ALLL is our estimation of incurred losses within the existing loan portfolio. We allocate the ALLL throughout the loan portfolio based on our assessment of the underlying risks associated within each loan segment. Our assessments include allocations based on specific impairment valuation allowances, historical charge-offs, internally assigned credit risk ratings, and past due and nonaccrual balances. A portion of the ALLL is not allocated to any one loan segment, but is instead a representation of other qualitative risks that reflect the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.
The following table summarizes our charge-offs, recoveries, provision for loan losses, and ALLL balances as of, and for the:

While we have experienced fluctuations in credit quality indicators in recent periods, credit quality remained strong at September 30, 2021. The COVID-19 pandemic led to the temporary and some permanent closures of businesses throughout the communities in which we serve, which also led to increased unemployment. We increased the ALLL during 2020 as a result of increased economic and environmental related risk factors, primarily driven by COVID-19. While these risk factors remain, improvement in credit quality indicators resulted in a reduction to the ALLL during the first nine months of 2021.

The economic impact from the COVID-19 pandemic could pose significant credit risk due to the potential inability of consumer and commercial borrowers to make contractual payments. In late March 2020, we implemented payment programs for borrowers to alleviate the financial setback due to the temporary closure of businesses and lost wages. These programs, along with the SBA PPP and government stimulus funding, could mask or delay the detection or reporting of deterioration in credit quality indicators. We continue to monitor the economic impact from COVID-19 as it relates to credit risk to ensure the ALLL is appropriate.
The following table illustrates the two main components of the ALLL as of:

| September 30 2021 |  | June 30 2021 |  | March 31 2021 |  | December 31 2020 |  | September 30 2020

Total | $ | 9,093 |  |  | $ | 9,360 |  |  | $ | 9,271 |  |  | $ | 9,744 |  |  | $ | 9,506 |
ALLL to gross loans |  |  |  |  |  |  |  |  |
Individually evaluated for impairment | 0.05 | % |  | 0.10 | % |  | 0.12 | % |  | 0.07 | % |  | 0.07 | %
Collectively evaluated for impairment | 0.68 | % |  | 0.68 | % |  | 0.66 | % |  | 0.72 | % |  | 0.66 | %
Total | 0.73 | % |  | 0.78 | % |  | 0.78 | % |  | 0.79 | % |  | 0.73 | %

While we utilize our best judgment and information available, the ultimate adequacy of the ALLL is dependent upon a variety of factors beyond our control, including the performance of our borrowers, the economy, and changes in interest rates. We closely monitor overall credit quality indicators and our policies and procedures related to the analysis of the ALLL to ensure that the ALLL remains at an appropriate level.
For further discussion of the allocation of the ALLL, see “Note 4 – Loans and ALLL” of our interim condensed consolidated financial statements.
Loans Past Due and Loans in Nonaccrual Status
Fluctuations in past due and nonaccrual status loans can have a significant impact on the ALLL. To determine the potential impact, and corresponding estimated losses, we analyze our historical loss trends on loans past due greater than 30 days and nonaccrual status loans for indications of additional deterioration.

| Total Past Due and Nonaccrual Loans
| September 30 2021 |  | June 30 2021 |  | March 31 2021 |  | December 31 2020 |  | September 30 2020

Total | $ | 3,498 |  |  | $ | 3,913 |  |  | $ | 5,863 |  |  | $ | 9,610 |  |  | $ | 7,217 |
Total past due and nonaccrual loans to gross loans | 0.28 | % |  | 0.32 | % |  | 0.49 | % |  | 0.78 | % |  | 0.55 | %

Loans past due and in nonaccrual status continued to decline during the third quarter of 2021 as a result of increased credit quality. A summary of loans past due and in nonaccrual status, including the composition of the ending balance of nonaccrual status loans by type, is included in “Note 4 – Loans and ALLL” of our interim condensed consolidated financial statements.

Troubled Debt Restructurings
We have taken a proactive approach modifying loans to assist borrowers who are willing to work with us, thus making them less likely to default, and to avoid foreclosure. This approach has permitted certain borrowers to accept a payment structure that will allow them to continue making payments in lieu of foreclosure. Modifications have been successful for us and our customers as very few of the modified loans have resulted in foreclosures. The majority of modifications result in terms that satisfy our criteria for continued interest accrual. TDRs that have been placed in nonaccrual status may be placed back on accrual status after six months of continued performance and achievement of current payment status.
We restructure debt with borrowers who, due to financial difficulties, are unable to service their debt under the original terms. We may extend the amortization period, reduce interest rates, allow temporary interest-only payment structures, forgive principal, forgive interest, or grant a combination of these modifications. Typically, the modifications are for a period of three years or less. There were no TDRs that were government sponsored as of September 30, 2021 or December 31, 2020.
Losses associated with TDRs, if any, are included in the estimation of the ALLL during the quarter in which a loan is identified as a TDR, and we review the analysis of the ALLL estimation each reporting period thereafter to ensure its continued appropriateness.
The following tables provide roll-forwards of TDRs for the:

The accrual of interest on commercial and agricultural loans, as well as residential real estate loans, is discontinued at the time a loan is 90 days or more past due unless the credit is well-secured and in the process of short-term collection. Upon transferring a loan 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 a charge-off is necessary. Consumer loans are typically charged-off no later than 180 days past due. Loans may be placed back on accrual status after six months of continued performance and achievement of current payment status. While the level of nonperforming loans has fluctuated in recent periods, it remains low in comparison to peer banks.
The following table summarizes nonaccrual loans as of:

ATM and debit card fees fluctuate from period to period based primarily on their usage. The usage of ATM and debit cards has increased during 2021 and this trend is expected to continue during the remainder of 2021. As such, we anticipate fees during the remainder of 2021 will continue to increase as a result of usage.
Service charges and fees on deposit accounts declined in 2020 as a result of waived fees. In response to the COVID-19 pandemic, which led to an increase in the need for electronic services and products, we elected to remove select deposit account related charges and fees and temporarily waive some charges and fees to ease the financial stress of our customers. Despite

some fees being removed, fee income has increased during 2021 but has yet to reach pre-pandemic levels. As such, service charges and fees during the remainder of 2021 are expected to exceed 2020 levels.
OMSR income results are driven, in part, by changes in offering rates on residential mortgage loans, anticipated prepayments in the servicing-retained portfolio, and the volume of loans within the servicing-retained portfolio. Increased prepayment speeds, as a result of a decline in interest rates during the first quarter of 2020, were the primary driver of the losses recognized during the first nine months of 2020. During 2021, the volume of loans serviced decreased, which decreases the value of the servicing rights, and the prepayment speeds increased. Both of these factors have contributed to the recognition of a loss during 2021. OMSR income during the remainder of 2021 may continue to experience fluctuations and could vary from 2020 levels.
The increase in wealth management fees in the first nine months of 2021 was driven by a combination of the growth in the stock market and increased new business activity in comparison to the same period last year. Wealth management fees during the remainder of 2021 is expected to exceed 2020 levels.
Net gain on sale of mortgage loans fluctuates as the result of a change in the amount of loans sold, loan pricing and interest rates. The amount of loans sold is driven by customer demand and balance sheet management strategies. We experienced a significant increase in loan demand during most of 2020 and into 2021 which led to an increase in the number and dollar amount of loans sold. As such, net gain on sale of mortgage loans increased significantly. In mid-2021, we decided to retain more loan originations on the balance sheet, thereby decreasing the number of mortgage loans sold, which had an impact on the net gain on loans sold. As demand is expected to slow during the remainder of 2021, net gain on sale of mortgage loans is not expected to exceed 2020 levels.
We recognized gains during the first nine months of 2021 and 2020 from the redemption of corporate owned life insurance policies in connection with the passing of retired bank employees.
We sold our membership interest in our joint venture investment in Corporate Settlement Solutions, LLC during the fourth quarter of 2020.
The fluctuations in all other noninterest income are spread throughout various categories, none of which are individually significant.

We have experienced increased usage of ATM and debit cards which has resulted in increased income and also increased ATM and debit card expenses. Based on the anticipated continuation of increased ATM and debit card usage, expenses during the remainder of 2021 are anticipated to exceed 2020 levels.
Donations and community relations increased during 2020 as a result of initiatives designed to deepen and strengthen our relationship with the communities in which we operate and serve which includes an expanded footprint. In addition to providing monetary contributions, some of these initiatives include volunteering our time, which is not a component of donations and community relations costs. While government restrictions and temporary business closures related to COVID-19 impacted our ability to maintain the level of support in the first quarter of 2021, we have since increased the level of community support during the second and third quarters of 2021.
The fluctuations in all other noninterest expenses are spread throughout various categories, none of which are individually significant.

As shown above, total assets increased $125,323 from December 31, 2020, driven primarily by an increase in AFS securities. Purchases of AFS securities during 2021 totaled $240,079 and were partially funded by a $125,999 increase in customer deposits. We experienced a $10,247 increase in loans during the first nine months of 2021 which was largely driven by an increase in residential mortgages.

Loan demand has been negatively impacted by the strong competition for new commercial loan opportunities while some customers hesitated to borrow due to the pandemic. Advances to mortgage brokers, within the commercial loan portfolio, was the driver behind the decline during 2021 as participation in this mortgage purchase program halted during most of 2021. At the end of the third quarter, activity with mortgage brokers resumed and contributed to the growth in the commercial portfolio. While we've recently experienced an increase in commercial loan demand, forgiveness of the remaining SBA PPP loans could lead to a decline in the commercial loan portfolio during the remainder of 2021. Agricultural loans have declined over the last year due to the competitive lending environment. Residential mortgage lending activities have increased since mid-2020 as interest rates declined. Growth is expected to continue in both the residential mortgage and consumer loan portfolios during the remainder of 2021.

Total deposits have increased over the past 12 months with significant growth in non-contractual deposits, such as demand and savings deposits. This trend is anticipated to continue during 2021 as the financial markets continue to exhibit significant signs of instability. Additionally, government stimulus programs have driven growth in deposits. We experienced a decline in certificates of deposit over the past year as a result of the low interest rate environment with customers moving their funds into demand and savings accounts. Brokered certificates of deposit offer another source of funding and may fluctuate from period to period based on our funding needs, including changes in assets such as loans and investments. During 2020, we used excess funds to reduce higher-cost deposits, such as brokered certificates of deposit. This trend continued in 2021 as we paid off the remaining balance of brokered deposits as they matured. This is expected to continue with other higher-cost deposits during the remainder of 2021.

The primary objective of our investing activities is to provide for safety of the principal invested. Secondary considerations include providing earnings and liquidity while managing our overall exposure to changes in interest rates. Over the last two years, the flat yield curve encouraged the use of excess funds to reduce higher-cost borrowings as opposed to investing in AFS securities. However, based on balance sheet strategies, excess funds above what is required to retire future maturities of higher-cost funding sources was prudently deployed to purchase of AFS securities in future periods.

Borrowed funds include FHLB advances, securities sold under agreements to repurchase, subordinated debt, and federal funds purchased. The balance of borrowed funds fluctuates from period to period based on our funding needs that arise from changes in loans, investments, and deposits. To provide balance sheet growth, we may utilize borrowings and brokered deposits to fund earning assets. The following table displays borrowed funds balances as of:

During the fourth quarter of 2020, we elected to extinguish $100,000 of FHLB advances based on our level of cash reserves and strategic initiatives. Due to a significant increase in one account during the fourth quarter of 2020 and the second quarter of 2021, our level of securities sold under agreements to repurchase increased as of December 31, 2020 and June 30, 2021. These increases are expected to be short-term; therefore, we anticipate a decline in the balance of securities sold under agreements during the remainder of 2021. On June 2, 2021, we completed a private placement of $30,000 in aggregate principal amount of 3.25% Fixed-to-Floating Rate Subordinated Notes due 2031 (the "Notes"). The Notes will initially bear a fixed interest rate of 3.25% until June 15, 2026, after which time until maturity on June 15, 2031, the interest rate will reset quarterly to an annual floating rate equal to the then-current 3-month SOFR plus 256 basis points. The Notes are redeemable by us at our option, in whole or in part, on or after June 15, 2026. The Notes are not subject to redemption at the option of the holders.
Contractual Obligations and Loan Commitments
We have various financial obligations, including contractual obligations and commitments related to deposits and borrowings, which may require future cash payments. We also have loan related commitments that may impact liquidity. The commitments include unused lines of credit, commercial and standby letters of credit, and commitments to grant loans. These commitments to grant loans include residential mortgage loans with the majority committed to be sold to the secondary market. Many of these commitments historically have expired without being drawn upon and do not necessarily represent our future cash requirements.
We are party to credit related financial instruments with off-balance-sheet risk. These financial instruments are entered into in the normal course of business to meet the financing needs of our customers. These financial instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The contractual or notional amounts of these instruments reflect the extent of involvement we have in a particular class of financial instrument.
Our exposure to credit-related loss in the event of nonperformance by the counterparties to the financial instruments for commitments to extend credit and standby letters of credit could be up to the contractual notional amount of those instruments.

We use the same credit policies when analyzing the creditworthiness of counterparties as we do for extending loans to customers. No significant losses are anticipated as a result of these commitments.
Capital
Capital consists solely of common stock, retained earnings, and accumulated other comprehensive income (loss). We are authorized to raise capital through dividend reinvestment, employee and director stock purchases, and shareholder stock purchases. Pursuant to these authorizations, we issued 52,523 shares or $1,196 of common stock during the first nine months of 2021, as compared to 184,144 shares or $3,274 of common stock during the same period in 2020. In early 2021, we implemented a change to our dividend reinvestment plan which impacted the volume of shares issued. We also offer the Directors Plan in which participants purchase stock units through deferred fees, in lieu of cash payments. Pursuant to this plan, we increased shareholders’ equity by $343 and $334 during the nine-month periods ended September 30, 2021 and 2020, respectively. We also grant restricted stock awards pursuant to the RSP. Pursuant to this plan, we increased shareholders’ equity by $58 during the first nine months of 2021.
We have publicly announced a common stock repurchase plan. Pursuant to this plan, we repurchased 123,160 shares or $2,699 of common stock during the first nine months of 2021 and 87,047 shares or $1,619 during the first nine months of 2020. As of September 30, 2021, we were authorized to repurchase up to an additional 479,796 shares of common stock.
The FRB has established minimum risk based capital guidelines. Pursuant to these guidelines, a framework has been established that assigns risk weights to each category of on and off-balance-sheet items to arrive at risk adjusted total assets. Regulatory capital is divided by the risk adjusted assets with the resulting ratio compared to the minimum standard to determine whether a corporation has adequate capital.
The common equity tier 1 capital ratio has a minimum requirement of 4.50%. The minimum standard for primary, or Tier 1 capital is 6.00% and the minimum standard for total capital is 8.00%. The minimum requirements presented below include the minimum required capital levels based on the Basel III Capital Rules. Capital requirements to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules. The following table sets forth these requirements and our ratios as of:

| September 30, 2021 |  | December 31, 2020
| Actual |  | Minimum Required - BASEL III |  | Required to be Considered Well Capitalized |  | Actual |  | Minimum Required - BASEL III |  | Required to be Considered Well Capitalized
Common equity tier 1 capital | 13.07 | % |  | 7.00 | % |  | 6.50 | % |  | 12.97 | % |  | 7.00 | % |  | 6.50 | %
Tier 1 capital | 13.07 | % |  | 8.50 | % |  | 8.00 | % |  | 12.97 | % |  | 8.50 | % |  | 8.00 | %
Total capital | 16.03 | % |  | 10.50 | % |  | 10.00 | % |  | 13.75 | % |  | 10.50 | % |  | 10.00 | %
Tier 1 leverage | 8.37 | % |  | 4.00 | % |  | 5.00 | % |  | 8.37 | % |  | 4.00 | % |  | 5.00 | %

Total capital includes Tier 1 capital and Tier 2 capital. Tier 2 capital includes a permissible portion of the allowances for loan and lease losses and subordinated debt, net of unamortized issuance costs. There are no significant regulatory constraints placed on our capital. At September 30, 2021, the Bank also exceeded minimum capital requirements.
Liquidity
Liquidity is monitored regularly by our ALCO, which consists of members of senior management. The committee reviews projected cash flows, key ratios, and liquidity available from both primary and secondary sources.
Our primary sources of liquidity are cash and cash equivalents and unencumbered AFS securities. These categories totaled $584,135 or 28.05% of assets as of September 30, 2021, compared to $444,051 or 22.69% as of December 31, 2020. The increase in the amount and percentage of primary liquidity is a direct result of an increase in market deposits and a deliberate reduction in non-market funding which required collateralization. Liquidity is important for financial institutions because of their need to meet loan funding commitments, depositor withdrawal requests, and various other commitments including expansion of operations, investment opportunities, and payment of cash dividends. Based on these same factors, daily liquidity could vary significantly.
Deposit accounts are our primary source of funds. Our secondary sources include the ability to borrow from the FHLB, from the FRB, and through various correspondent banks in the form of federal funds purchased and a line of credit. These funding methods typically carry a higher interest rate than traditional market deposit accounts. In recent periods, we have elected to use excess funds to reduce borrowings and other higher-cost funding sources. Some borrowed funds, including FHLB advances,

FRB Discount Window advances, and repurchase agreements, require us to pledge assets, typically in the form of AFS securities or loans, as collateral. As of September 30, 2021, we had available lines of credit of $260,815.
Our stress testing of liquidity increased during 2020 and continues to evolve due to economic uncertainly as a result of COVID-19. Our liquidity position remained strong at September 30, 2021, which is illustrated in the following table:

| September 30 2021

Fair Value
We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. AFS securities, cash flow hedge derivative instruments and certain liabilities are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record at fair value other assets on a nonrecurring basis, such as mortgage loans AFS, impaired loans, goodwill, foreclosed assets, OMSR, and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write downs of individual assets.
For further information regarding fair value measurements see “Note 11 – Fair Value” of our interim condensed consolidated financial statements.
Market Risk
Our primary market risks are interest rate risk and liquidity risk. IRR is the exposure of our net interest income to changes in interest rates. IRR results from the difference in the maturity or repricing frequency of a financial institution's interest earning assets and its interest bearing liabilities. Managing IRR is the fundamental method by which financial institutions earn income and create shareholder value. Excessive exposure to IRR could pose a significant risk to our earnings and capital.
The FRB has adopted a policy requiring banks to effectively manage the various risks that can have a material impact on safety and soundness. The risks include credit, interest rate, liquidity, operational, and reputational. We have policies, procedures, and internal controls for measuring and managing these risks. Specifically, our Funds Management policy and procedures include defining acceptable types and terms of investments and funding sources, liquidity requirements, limits on investments in long-term assets, limiting the mismatch in repricing opportunities of assets and liabilities, and the frequency of measuring and reporting to our Board of Directors.
The primary technique to measure IRR is simulation analysis. Simulation analysis forecasts the effects on the balance sheet structure and net interest income under a variety of scenarios that incorporate changes in interest rates, the shape of yield curves, interest rate relationships, loan prepayments, and funding sources. These forecasts are compared against net interest income projected in a stable interest rate environment. While many assets and liabilities reprice either at maturity or in
58

Table of Contents
accordance with their contractual terms, several balance sheet components demonstrate characteristics that require an evaluation to more accurately reflect their repricing behavior. Key assumptions in the simulation analysis include prepayments on loans, probable calls of investment securities, changes in market conditions, loan volumes and loan pricing, deposit sensitivity, and customer preferences. These assumptions are inherently uncertain as they are subject to fluctuation and revision in a dynamic rate environment. As a result, the simulation analysis cannot precisely forecast the impact of rising and falling interest rates on net interest income. Actual results will differ from simulated results due to many other factors, including changes in balance sheet components, interest rate changes, changes in market conditions, and management strategies. We regularly monitor our projected net interest income sensitivity to ensure that it remains within established limits.
Gap analysis, the secondary method to measure IRR, measures the cash flows and/or the earliest repricing of our interest bearing assets and liabilities. This analysis is useful for measuring trends in the repricing characteristics of the balance sheet. Significant assumptions are required in this process because of the embedded repricing options contained in assets and liabilities. Residential real estate and consumer loans allow the borrower to repay the balance prior to maturity without penalty, while commercial and agricultural loans may have prepayment penalties. The amount of prepayments is dependent upon many factors, including the interest rate of a given loan in comparison to the current offering rates, the level of home sales, and the overall availability of credit in the market place. Generally, a decrease in interest rates will result in an increase in cash flows from these assets. A significant portion of our securities are callable or have prepayment options. The call and prepayment options are more likely to be exercised in a period of decreasing interest rates. Savings and demand accounts may generally be withdrawn on request without prior notice. The timing of cash flows from these deposits is estimated based on historical experience. Certificates of deposit have penalties that discourage early withdrawals.
We do not believe there has been a material change in the nature or categories of our primary market risk exposure, or the particular markets that present the primary risk of loss. We do not know of or expect there to be any material change in the general nature of our primary market risk exposure in the near term, and we do not expect to make material changes to our market risk methods in the near term. We may change those methods in the future to adapt to changes in circumstances or to implement new techniques.
Our primary market risk exposures related to the COVID-19 pandemic remain uncertain. A review of our market risk methods are ongoing and modeling is incorporating additional assumptions to account for this uncertainty related to this crisis. Repricing, cash flows, and prepayment projections for loans and mortgage-backed securities are not expected to behave as they would be expected to in a more stable interest rate environment. The SBA PPP loan is a newer instrument and has payment characteristics that could create uncertainty in our assumptions. Customer deposit levels may experience unusual fluctuations due to government support programs, customer and business needs, and general money supply. We continue to closely monitor customer and economic indicators to develop more precise market risk assumptions as the economic impact of the crisis continues to reveal itself.

(C)Repurchases of Common Stock
We have adopted and publicly announced a common stock repurchase plan. The plan was last amended on April 28, 2021, to allow for the repurchase of an additional 500,000 shares of common stock after that date. These authorizations do not have expiration dates. As common shares are repurchased under this plan, they are retired and revert back to the status of authorized, but unissued common shares.
The following table provides information for the three-month period ended September 30, 2021, with respect to this plan:

| Common Shares Repurchased |  | Total Number of Common Shares Purchased as Part of Publicly Announced Plan or Program |  | Maximum Number of Common Shares That May Yet Be Purchased Under the Plans or Programs
