PROXY STATEMENT
General Information
This Proxy Statement is furnished in connection with the solicitation of proxies, to be voted at our Annual Meeting of Shareholders (the “Annual Meeting”) which is to held on Tuesday, May 7, 2024 at 5:00 p.m. at the Courtyard by Marriott, 2400 East Campus Drive, Mt. Pleasant, Michigan, or at any adjournment or adjournments thereof, for the purposes set forth in the accompanying Notice of the Annual Meeting of Shareholders and in this Proxy Statement.
This Proxy Statement has been mailed on March 25, 2024 to all holders of record of common stock as of the record date. If a shareholder’s shares are held in the name of a broker, bank, or other nominee, then that party should give the shareholder instructions for voting the shareholder’s shares.
Voting at the Meeting
We have fixed the close of business on March 15, 2024 as the record date for the determination of shareholders entitled to notice of, and to vote at, the Annual Meeting and any adjournment or adjournments thereof. We have only one class of common stock and no preferred stock. As of March 15, 2024, there were 7,498,626 shares of stock outstanding. Each outstanding share entitles the holder thereof to one vote on each separate matter presented for vote at the meeting. You may vote on matters that are properly presented at the Annual Meeting by attending the meeting and casting a vote, signing and returning the enclosed proxy, voting on the internet, or voting by phone. You may change your vote or revoke your proxy at any time before it is voted at the Annual Meeting by filing with Isabella Bank Corporation (the “Corporation”) an instrument revoking it, filing a duly executed proxy bearing a later date (including a proxy given over the internet or by phone) or by attending the meeting and electing to vote in person. You are encouraged to vote by mail, internet, or phone.
A quorum must be present in order to hold the Annual Meeting. A quorum is present if a majority of the shares of common stock entitled to vote are represented in person or by proxy. If you execute and return a proxy, those shares will be counted to determine if there is a quorum, even if you abstain or fail to vote on any of the proposals.
Your broker may not vote on Proposal 1 if you do not furnish instructions for such proposal. You should instruct the broker to vote the shares, or else your shares will be considered “broker non-votes.” Broker non-votes are shares held by brokers or nominees as to which voting instructions have not been received from the shares’ beneficial owner or the individual entitled to vote those shares and the broker or nominee does not have discretionary voting power under rules applicable to broker-dealers. Under these rules, Proposal 1 is not an item on which brokerage firms may vote in their discretion on your behalf unless you have furnished voting instructions. On the other hand, under these rules your broker will be able to vote on Proposal 2- ratification of the appointment of Rehmann Robson LLC (“Rehmann”) as our independent registered public accounting firm.
At this year’s Annual Meeting, you will elect three directors to serve for a term of three years. You may vote in favor or withhold your vote with respect to any or all nominees. Directors are elected by a plurality of the votes cast at the Annual Meeting. Abstentions and shares not voted, including broker non-votes, have no effect on the elections.
Ratification of the appointment of Rehmann requires that the number of votes cast “FOR” the proposal exceed the number of votes cast “AGAINST” such proposal. In counting votes on the ratification of the appointment of Rehmann as our independent registered public accounting firm, abstentions and broker non-votes will have no effect on the outcome of the vote.

Proposal 1 - Election of Directors
The Board of Directors (the “Board”) currently consists of twelve (12) members divided into three classes, with the directors in each class being elected for a term of three years. The Board decreased from 13 to 11 members in May of 2023 when G. Charles Hubscher and David J. Maness retired from the Board. The Board increased from 11 to 12 members with the appointment of Neil M. McDonnell, effective January 31, 2024. The Board will decrease from 12 to 11 members as Richard L. McGuirk will not stand for re-election at the Annual Meeting. At the Annual Meeting, Jill Bourland, Jae A. Evans, and Jerome E. Schwind, whose current terms expire at the Annual Meeting, have been nominated for election to serve through the 2027 Annual Meeting.
Except as otherwise specified, proxies will be voted for the election of the three nominees. If a nominee becomes unable or unwilling to serve, proxies will be voted for such other person, if any, as shall be designated. However, we know of no reason to anticipate that this will occur. Each of the nominees has agreed to serve as a director if elected.
Nominees and current directors, including their principal occupation for the last five or more years, age, and length of service as a director, are listed below.
We recommend that you vote FOR the election of each of the nominees.
Director Qualifications
Board members are highly qualified and represent your best interests. We select nominees who:
•Have extensive business leadership.
•Bring a diverse perspective and experience.
•Are objective and collegial.
•Have high ethical standards and have demonstrated sound business judgment.
•Are willing and able to commit the significant time and effort to effectively fulfill their responsibilities.

Proposal 2 - Ratification of Independent Registered Public Accounting Firm
The Audit Committee is directly responsible for the appointment, compensation, retention, and oversight of our independent registered public accounting firm. The Audit Committee engages in an annual evaluation of the independent registered public accounting firm’s qualifications, assessing a wide variety of factors.
After assessing the performance and independence of Rehmann, the Corporation's current independent registered public accounting firm, the Audit Committee believes it is in the best interest of the Corporation and its shareholders to retain Rehmann. The Audit Committee has appointed Rehmann as our independent auditors for the year ending December 31, 2024. The Audit Committee seeks shareholder ratification of this appointment. Rehmann has served as our independent registered public accounting firm since 1996.
For information related to the Audit Committee's process and Rehmann's fees, refer to the “Independent Registered Public Accounting Firm” section of this report. A representative of Rehmann is expected to be present at the Annual Meeting to respond to appropriate questions from shareholders and to make any comments Rehmann believes are appropriate.
In the event shareholders do not ratify the appointment, the appointment will be reconsidered by the Audit Committee and the Board of Directors. Even if the selection is ratified, the Audit Committee, in its discretion, may select a different registered public accounting firm at any time during the year if it determines that such a change would be in the best interest of the Corporation and its shareholders.
Unless otherwise instructed, validly executed proxies will be voted “FOR” this resolution.
We recommend that you vote FOR this proposal to ratify the appointment of Rehmann Robson LLC as our independent registered public accounting firm for the year ending December 31, 2024.
Corporate Governance
Director Independence
We have adopted the director independence standards as defined under the NASDAQ listing requirements. We have determined that Dr. Jeffrey J. Barnes, Jill Bourland, Melinda M. Coffin, Thomas L. Kleinhardt, Richard L. McGuirk, Sarah R. Opperman, Chad R. Payton, Vicki L. Rupp, and Gregory V. Varner are independent directors. Jae A. Evans is not independent as he retired as President and CEO of Isabella Bank Corporation and CEO of Isabella Bank on January 4, 2024. Jerome E. Schwind is not independent as he is employed as President and CEO of Isabella Bank Corporation and CEO of Isabella Bank. Neil M. McDonnell is not independent as he is employed as Chief Financial Officer of Isabella Bank Corporation and President of Isabella Bank.
Board Leadership Structure and Risk Oversight
Our Governance Policy provides that only directors who are deemed to be independent as set forth by the NASDAQ listing requirements and SEC rules are eligible to hold the office of chairperson. Additionally, the chairpersons of Board established committees must also be independent directors. It is our belief that having a separate chairperson and CEO best serves the interest of the shareholders. The Board elects its chairperson at the first Board meeting following the Annual Meeting. Independent members of the Board meet without inside directors at least twice per year.
Management is responsible for our day-to-day risk management and the Board’s role is to engage in informed oversight. The Board utilizes committees to oversee risks associated with compensation and governance. The Isabella Bank Board of Directors is responsible for overseeing credit, investment, information technology, interest rate, and trust risks. The chairpersons of the respective boards or committees report on their activities on a regular basis.
Our Audit Committee is responsible for overseeing the integrity of our consolidated financial statements, the independent auditors’ qualifications and independence, the performance of our internal audit function and those of independent auditors, our system of internal controls, our financial reporting and system of disclosure controls, and our compliance with legal and regulatory requirements and with our Code of Conduct and Business Ethics.

The Board has approved a Nominating and Corporate Governance Committee Charter which is available on the Bank’s website: www.isabellabank.com.
The Nominating and Corporate Governance Committee is responsible for evaluating and recommending individuals for nomination to the Board for approval. This Committee, in evaluating nominees, including incumbent directors and any nominees put forth by shareholders, considers business experience, skills, character, judgment, leadership experience, and their knowledge of the geographical markets, business segments or other criteria the Committee deems relevant and appropriate based on the current composition of the Board. This Committee considers diversity in identifying members with respect to our geographical markets served, the industry knowledge and experience of the nominee, and community relations of the nominee.
The Nominating and Corporate Governance Committee will consider, as potential nominees, persons recommended by shareholders. Recommendations should be submitted in writing to the Secretary of the Corporation, 401 N. Main St., Mt. Pleasant, Michigan 48858 and include the shareholder’s name, address and number of shares of the Corporation owned by the shareholder.

Compensation and Human Resource Committee

Audit Committee Report
The Audit Committee oversees the financial reporting process on behalf of the Board. The 2023 Audit Committee consisted of directors Bourland, Coffin, Kleinhardt, Opperman (ex-officio), and Payton.*
The Audit Committee is responsible for pre-approving all auditing services and permitted non-audit services by our independent auditors, or any other auditing or accounting firm, if those fees are reasonably expected to exceed 5.0% of the current year agreed upon fee for independent audit services. The Audit Committee has established general guidelines for the permissible scope and nature of any permitted non-audit services in connection with its annual review of the audit plan and reviews the guidelines with the Board.
Management has the primary responsibility for the consolidated financial statements and the reporting process including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited consolidated financial statements in the Annual Report with management including a discussion of the acceptability of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the consolidated financial statements. The Audit Committee also reviewed with management and the independent auditors, management’s assertion on the design and effectiveness of our internal control over financial reporting as of December 31, 2023.
The Audit Committee reviewed with our independent auditors, who are responsible for expressing an opinion on the conformity of those audited consolidated financial statements with accounting principles generally accepted in the United States of America, their judgments as to the acceptability of our accounting principles and such other matters as are required to be discussed with the Audit Committee by the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), including those described in Auditing Standard No. 1301, “Communications with Audit Committees”, as may be modified or supplemented. In addition, the Audit Committee has received the written disclosures and the letter from the independent auditors required by PCAOB Rule 3526, “Communication with Audit Committees Concerning Independence”, as may be modified or supplemented, and has discussed this issue with the independent auditors.
The Audit Committee discussed with our internal and independent auditors the overall scope and plans for their respective audits. The Audit Committee meets with the internal and external independent auditors, with and without management present, to discuss the results of their examinations, their evaluations of our internal controls, and the overall quality of our financial reporting process. The Audit Committee held five meetings during 2023.
In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors (and the Board has approved) that the audited consolidated financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2023 for filing with the Securities and Exchange Commission. The Audit Committee has appointed Rehmann Robson LLC as the independent auditors for the 2024 audit.

Pension Benefits
Defined Benefit Pension Plan. We sponsor the Isabella Bank Corporation Pension Plan (“Defined Benefit Pension Plan”), a frozen defined benefit pension plan. The curtailment, which was effective March 1, 2007, froze the current participant’s accrued benefits as of that date and limited participation in the plan to eligible employees as of December 31, 2006. Due to the curtailment of the plan, the number of years of credited service was frozen. As such, the years of credited service for the plan may differ from the participant’s actual years of service.
Annual contributions are made to the plan as required by accepted actuarial principles, applicable federal tax laws, and to pay expenses related to operating and maintaining the plan. The amount of contributions on behalf of any one participant cannot be separately or individually computed.
Pension plan benefits are based on years of service and the employees’ five highest consecutive years of compensation out of the last ten years of service, through December 31, 2006.
A participant may earn a benefit for up to 35 years of accredited service. Earned benefits are 100% vested after five years of service. Benefit payments normally start when a participant reaches age 65. A participant with more than five years of service may elect to take early retirement benefits anytime after reaching age 55. Benefits payable under early retirement are reduced actuarially for each month prior to age 65 in which benefits begin.
Under the provisions of the plan, participants are eligible for early retirement after reaching the age of 55 with at least five years of service. The early retirement benefit amount is the accrued benefit payable at normal retirement date reduced by 5/9% for each of the first 60 months and 5/18% for each of the next 60 months that the benefit commencement date precedes the normal retirement date.
Retirement Bonus Plan. We sponsor the Isabella Bank Corporation Retirement Bonus Plan (“Retirement Bonus Plan”). This nonqualified plan is intended to provide eligible employees with additional retirement benefits. To be eligible, the employee needed to be an employee on January 1, 2007, and be a participant in our frozen Executive Supplemental Income Agreement. Participants were also required to be an officer with at least 10 years of service as of December 31, 2006. We have sole and exclusive discretion to add new participants to the Retirement Bonus Plan by authorizing such participation pursuant to action of the Board.
9

An initial amount was credited for each eligible employee as of January 1, 2007. Subsequent amounts have been credited on each allocation date thereafter as defined in the Retirement Bonus Plan. The amount of the initial allocation and the annual allocation shall be determined pursuant to the payment schedule adopted at our sole and exclusive discretion, as set forth in the Retirement Bonus Plan.
Under the provisions of the Retirement Bonus Plan, participants are eligible for early retirement upon attaining 55 years of age. There is no difference between the calculation of benefits payable upon early retirement and normal retirement; however, the participant would not receive their full benefit under early retirement.
Nonqualified Deferred Compensation
Directors Plan. Under the Isabella Bank Corporation and Related Companies Deferred Compensation Plan for Directors (“Directors Plan”), directors, including named executive officers who serve as directors, are required to invest at least 25% of their board fees in our common stock and may invest up to 100% of their earned fees based on their annual election. These amounts are reflected in footnote 1 to the Summary Compensation Table. These stock investments can be made either through deferred fees or through the purchase of shares through the Isabella Bank Corporation Stockholder Dividend Reinvestment and Employee Stock Purchase Plan (“DRIP Plan”). Deferred fees, under the Directors Plan, are converted on a quarterly basis into stock units of our common stock based on the fair value of a share of our common stock as of the relevant valuation date. Stock units credited to a participant’s account are eligible for stock and cash dividends as paid. DRIP Plan shares are purchased pursuant to the DRIP Plan.
Distribution of deferred fees from the Directors Plan occurs when the participant retires from the Board or upon the occurrence of certain other events. The participant is eligible to receive distributions in the form of shares of our common stock of all of the stock units that are then in his or her account, and any unconverted cash will be converted to and rounded up to a whole share of stock and distributed, as well. Any common stock issued from deferred fees under the Directors Plan will be considered restricted stock under the Securities Act of 1933, as amended. Common stock purchased through the DRIP Plan are not considered restricted stock under the Securities Act of 1933, as amended.
SERP. Under the supplemental executive retirement plan (“SERP”), we may promise deferred compensation benefits to employees who are members of a select group of management or highly compensated employees, which may include the named executive officers. The SERP authorizes us to make annual and discretionary credits to a participant’s SERP account pursuant to a participation agreement with the participant that sets forth the amount and timing of any annual credits and the vesting, payment, “clawback” and other terms to which the credits are subject.
The SERP provides default terms that may be modified by a participant’s participation agreement, including default vesting, interest and payment terms. Under the SERP’s default vesting terms, a participant is initially unvested in the participant’s SERP account and becomes 100% vested upon attaining normal retirement age, retirement, involuntary separation from service without cause, death, disability or a change in control. Special vesting rules apply to amounts that are credited after a change in control. Under the SERP’s interest rule, a participant’s account balance is credited with interest annually, the rate of which may be changed and is based on Federated Investor's Institutional Money Market Management Fund yield (MMPXX) for the current plan year, updated annually. Under the SERP’s default payment terms, a participant’s vested and nonforfeited account balance will be paid in a single cash lump sum within 90 days after the first to occur of the participant’s separation from service (subject to a six-month delay for a “specified employee”), death, disability, or any date specified in the participant’s participation agreement. The SERP also includes restrictive covenants that restrict a participant’s ability to compete with us and certain other activities.
Executive Cash Incentive Plan. The Executive Cash Incentive Plan provides potential payouts for the President and CEO, Bank President, and CFO based on achievement of personal and corporate goals. The maximum potential payouts under the plan range from 22% to 35% of the employee's annual salary and are subject to “clawback” provisions. The Compensation and Human Resource Committee is responsible for establishing personal goals and measuring the achievement of personal goals for the President and CEO. This Committee also reviews the performance of the President and CEO. The President and CEO recommends to the Compensation and Human Resource Committee the measurement and achievement of personal and corporate goals for the Bank President and CFO.
Restricted Stock Plan. The Isabella Bank Corporation Restricted Stock Plan ("RSP") is an equity-based bonus plan. The primary purpose of the plan is to promote our growth and profitability by attracting and retaining executive officers and key employees of outstanding competence through ownership of equity that provides them with incentives to achieve corporate objectives. 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. Under the RSP, the Board of Directors may grant restricted stock awards to eligible employees on an annual basis based on satisfactory achievement of performance targets and measures established by the Board of Directors. If these grant conditions are not satisfied, then the award of
10

restricted shares will lapse or be adjusted appropriately, at the discretion of the Board of Directors. Restricted stock awards granted are not fully transferable or vested until certain conditions are met, as stated in the plan, and are subject to “clawback” provisions.
Potential Payments Upon Termination or Change in Control
The estimated amounts payable to each named executive officer upon severance from employment, retirement, termination upon death or disability or termination following a change in control are described below. For all termination scenarios, the amounts assume such termination took place as of December 31, 2023.
Any Severance of Employment
Regardless of the manner in which a named executive officer’s employment terminates, he or she is entitled to receive amounts earned during his or her term of employment. Such amounts include:
•Amounts accrued and vested through the Defined Benefit Pension Plan.
•Amounts accrued and vested through the Retirement Bonus Plan.
•Amounts credited and vested through the SERP.
•Amounts deferred in the Directors Plan.
•Amounts granted and vested through the Restricted Stock Plan.
•Eligible unused vacation and short-term disability pay.
Retirement
In the event of the retirement of an executive officer, the officer would receive the benefits identified above.
Death or Disability
In the event of death or disability of an executive officer, in addition to the benefits listed above, the executive officer will also receive payments under our life insurance plan or under our disability plan as appropriate.
Change in Control
We currently do not have a change in control agreement with any of the executive officers. Under the SERP, each participant would become 100% vested in their SERP account upon a change in control. Under certain conditions, following a change in control, if a participant is involuntarily terminated without cause or voluntarily terminates for good reason all uncredited annual credits would be credited to his or her SERP account. If termination took place on December 31, 2023, that would have resulted in an additional credit to Jae A. Evans’ SERP account of $0, Neil M. McDonnell's SERP account of $150,000, and Jerome E. Schwind's SERP account of $416,500 and a total credit for each individual of $874,663, $254,025, and $609,391, respectively.
Under the RSP, each participant would become 100% vested in their RSP account upon a change in control. Under certain conditions, following a change in control, if a participant is involuntarily terminated without cause or voluntarily terminates for good reason all nonvested shares would be fully vested. If termination took place on December 31, 2023, that would have resulted in vested shares to Jae A. Evans’ RSP account of 14,010 ($301,216), Neil M. McDonnell's RSP account of 5,580 ($119,970), and Jerome E. Schwind's RSP account of 7,482 ($160,864).

Relationship Between Pay and Performance
Compensation actually paid to the CEO from 2021 to 2022 decreased by $95,015, or 12%, and compensation actually paid from 2022 to 2023 decreased by $22,606, or 3%. The average compensation actually paid to the other NEOs as a group over the same periods decreased $103,835, or 19%, and $8,626, or 2%, respectively. The change in compensation actually paid for all periods was driven by a decline in stock awards, as a result of the achievement of less than 100% of the financial performance goals in connection to the stock awards and changes in the fair value of unvested awards. Over the same periods, cumulative total shareholder return decreased by 4% and 3% and net income increased by 14% and 18%, respectively.
The following graph illustrates the relationship during 2021-2023 between compensation actually paid to our CEO and average compensation actually paid to other NEOs as a group and total shareholder return (“TSR”):

(2) Includes fees for the fourth quarter of 2022 as a result of a change in the director fee payment structure.
(3) Retired from the Board effective May 9, 2023.
We paid an annual retainer of $40,000 to each non-employee director and $30,000 to each employee director of the Board during 2023. The chairperson of the Board is paid an additional retainer of $15,000, the Audit Committee chair is paid an additional retainer of $8,000, the Nominating & Corporate Governance chair is paid an additional retainer of $1,000, and the chairperson of the Compensation & Human Resource Committee is paid an additional retainer of $4,000.
Under the Directors Plan, upon a participant’s retirement from the Board, or the occurrence of certain other events, the participant is eligible to receive a distribution in the form of shares of our common stock of all of the stock units that are then credited to the participant's account. The plan does not allow for cash settlement. Stock issued under the Directors Plan is restricted stock under the Securities Act of 1933, as amended.
We established a Rabbi Trust to supplement the Directors Plan. The Rabbi Trust is an irrevocable grantor trust to which we may contribute assets for the limited purpose of funding a nonqualified deferred compensation plan. Although we may not reach the assets of the Rabbi Trust for any purpose other than meeting our obligations under the Directors Plan, the assets of the Rabbi Trust remain subject to the claims of our creditors. We may contribute cash or common stock to the Rabbi Trust from time to time for the sole purpose of funding the Directors Plan. The Rabbi Trust will use any cash that we may contribute to purchase shares of our common stock on the open market.
We transferred $1,461,971 to the Rabbi Trust in 2023, which held 150,581 shares of our common stock for settlement as of December 31, 2023. As of December 31, 2023, there were 3,538 stock units credited to participants’ accounts; such credits are unfunded as of such date to the extent that they are in excess of the stock and cash that has been credited to the Rabbi Trust. All amounts are unsecured claims against our general assets. The net cost of this benefit was $210,288 in 2023.

Indebtedness of and Transactions with Management
Certain directors and officers and members of their families were loan customers of the Bank, or have been directors or officers of corporations, members or managers of limited liability companies, or partners of partnerships which have had transactions with the Bank. In our opinion, all such transactions were made in the ordinary course of business and were substantially on the same terms, including collateral and interest rates, as those prevailing at the same time for comparable transactions with customers not related to the Bank. These transactions do not involve more than normal risk of collectability or present other unfavorable features. Total loans to these customers were approximately $19,527,000 and $20,963,000 as of December 31, 2023 and 2022.

Independent Registered Public Accounting Firm
The Audit Committee has appointed Rehmann as our independent auditors for the year ending December 31, 2024.
Fees for Professional Services Provided by Rehmann
The following table shows the aggregate fees billed by Rehmann for the audit and other services provided for:

| 2023 |  | 2022
Audit fees | $ | 387,700 |  |  | $ | 354,486 |
Audit related fees | 17,500 |  |  | 24,500 |
Tax fees | 21,085 |  |  | 21,725 |
Total | $ | 426,285 |  |  | $ | 400,711 |

The audit fees were for performing the integrated audit of our consolidated annual financial statements and the internal control report related to the Federal Deposit Insurance Corporation Improvement Act, reviews of interim financial statements included in our Quarterly Reports on Form 10-Q, and services that are normally provided by Rehmann in connection with statutory and regulatory filings or engagements.
The audit related fees are typically for various discussions related to the adoption and interpretation of new accounting pronouncements. During 2023, this included fees for procedures related to nonrecurring regulatory filings. Also included are fees for auditing of our employee benefit plans. The tax fees were for the preparation of our state and federal income tax returns and for consultation on various tax matters.
The Audit Committee has considered whether the services provided by Rehmann, other than the audit fees, are compatible with maintaining Rehmann’s independence and believes that the other services provided are compatible.

All non-audit services to be performed by Rehmann must be approved in advance by the Audit Committee if those fees are reasonably expected to exceed 5.0% of the current year agreed upon fee for independent audit and interim review services, so long as such services were recognized by the Corporation at the time of engagement to be non-audit services, and such services are promptly brought to the attention of the Audit Committee subsequent to completion of the audit. As permitted by SEC rules, the Audit Committee has authorized its chairperson to pre-approve audit, audit-related, tax and non-audit services, provided that such approved service is reported to the full Audit Committee at its next meeting.
As early as practicable in each calendar year, the independent auditor provides to the Audit Committee a schedule of the audit and other services that the independent auditor expects to provide or may provide during the next twelve months. The schedule will be specific as to the nature of the proposed services, the proposed fees, timing, and other details that the Audit Committee may request. The Audit Committee will by resolution authorize or decline the proposed services. Upon approval, this schedule will serve as the budget for fees by specific activity or service for the next twelve months.
A schedule of additional services proposed to be provided by the independent auditor, or proposed revisions to services already approved, along with associated proposed fees, may be presented to the Audit Committee for their consideration and approval at any time. The schedule will be specific as to the nature of the proposed service, the proposed fee, and other details that the Audit Committee may request. The Audit Committee will by resolution authorize or decline authorization for each proposed new service.
Applicable SEC rules and regulations permit waiver of the pre-approval requirements for services other than audit, review or attest services if certain conditions are met. Out of the services characterized above as audit-related, tax and other professional services, none were billed pursuant to these provisions in 2023 and 2022 without pre-approval.
