ISABELLA BANK CORPORATION 401 N. Main St Mt. Pleasant, Michigan 48858 PROXY STATEMENT

General Information

This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of Isabella Bank Corporation (the Corporation) a Michigan financial holding company, to be voted at the Annual Meeting of Shareholders of the Corporation to be held on Tuesday, May 3, 2011 at 5:00 p.m. at the Comfort Inn, 2424 S. Mission Street, Mt. Pleasant, Michigan, or at any adjournment or adjournments thereof, for the purposes set forth in the accompanying Notice of Annual Meeting of Shareholders and in this Proxy Statement.

This Proxy Statement has been mailed on April 8, 2011 to all holders of record of common stock as of the record date. If a shareholders shares are held in the name of a broker, bank or other nominee, then that party should give the shareholder instructions for voting the shareholders shares.

Voting at the Meeting

The Board of Directors of the Corporation has fixed the close of business on April 1, 2011 as the record date for the determination of shareholders entitled to notice of, and to vote at, the Annual Meeting of Shareholders and any adjournment thereof. The Corporation has only one class of common stock and no preferred stock. As of April 1, 2011, there were 7,546,866 shares of common stock of the Corporation outstanding. Each outstanding share entitles the holder thereof to one vote on each separate matter presented for vote at the meeting. Shareholders may vote on matters that are properly presented at the meeting by either attending the meeting and casting a vote or by signing and returning the enclosed proxy. If the enclosed proxy is executed and returned, it may be revoked at any time before it is exercised at the meeting. All shareholders are encouraged to date and sign the enclosed proxy, indicate their choice with respect to the matters to be voted upon, and return it to the Corporation.

The Corporation will hold the Annual Meeting of Shareholders if holders of a majority of the Corporations shares of common stock entitled to vote are represented in person or by proxy at the meeting. If a shareholder signs and returns the proxy, those shares will be counted to determine whether the Corporation has a quorum, even if the shareholder abstains or fails to vote on any of the proposals listed on the proxy.

A shareholders broker may not vote on the election of directors, the advisory vote to approve the named executive officers compensation or the advisory vote on the frequency of the vote on named executive officers compensation if the shareholder does not furnish instructions for such proposals. A shareholder should use the voting instruction card provided by the institution that holds his or her shares to instruct the broker to vote the shares or else the shareholders 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 beneficial owners or the persons 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, proposals one, two and three are not items on which brokerage firms may vote in their discretion on behalf of their clients if such clients have not furnished voting instructions.

At this years annual meeting, shareholders will elect five directors to serve for a term of three years. In voting on the election of directors, a shareholder may vote in favor of the nominees, vote against or withhold votes as to all nominees, or vote against or withhold votes as to specific nominees. Directors are elected by a plurality of the votes cast at the annual meeting. This means that the nominees receiving the greatest number of votes will be elected. Shares not voted, including broker non-votes, have no effect on the election of directors.

In voting on the advisory, nonbinding proposal to approve the executive compensation described in this proxy statement, a shareholder may vote in favor of the advisory proposal, vote against the advisory proposal or abstain from voting. A majority of the shares represented at the annual meeting and entitled to vote on this advisory proposal must be voted in favor of the proposal for it to pass. While this vote is required by law, it will neither be

XBRL Paragraph Pagebreak XBRL Pagebreak Begin

END PAGE WIDTH PAGEBREAK

BEGIN PAGE WIDTH XBRL Pagebreak End

binding on the Board of Directors, nor will it create or imply any change in the fiduciary duties of, or impose any additional fiduciary duty on the Board of Directors. In counting votes on the advisory, nonbinding proposal to approve executive compensation matters, abstentions will have the same effect as a vote against the proposal and broker non-votes will have no effect on the outcome of the vote.

In voting on the advisory, nonbinding proposal on how frequently a shareholder vote on executive compensation matters should be held, a shareholder may vote in favor of holding such a vote once every year, once every two years or once every three years, or may abstain from voting. Generally, approval of any proposal presented to the Corporations shareholders requires the affirmative vote of a majority of the shares represented at the meeting and entitled to vote on the proposal. However, because this vote is advisory and nonbinding, if none of the vote frequency options receives the affirmative vote of a majority of the shares represented at the meeting and entitled to vote on the proposal, the vote frequency option receiving the greatest number of votes will be considered the frequency option recommended by the Corporations shareholders. Even though this vote will not be binding on the Board of Directors, and it will not create or imply any change in the fiduciary duties of, or impose any additional fiduciary duty on, the Board of Directors, the Board of Directors will take into account the outcome of this vote in making a determination on the frequency that advisory votes on the Corporations executive compensation will be included in the Corporations proxy statements. In counting votes on the advisory, nonbinding proposal on how frequently the shareholder vote on the Corporations executive compensation should be held, abstentions and broker non-votes will have no effect on the outcome of the vote.

Proposal 1-Election of Directors

The Board of Directors currently consists of thirteen (13) members and is divided into three classes, with the directors in each class being elected for a term of three years. On December 31, 2010, in accordance with the Corporations bylaws, William J. Strickler and Theodore W. Kortes retired as members of the Corporations Board of Directors and the number of directors was reduced to thirteen (13). At the 2011 Annual Meeting of Shareholders five directors, Dennis P. Angner, Jeffrey J. Barnes, G. Charles Hubscher, David J. Maness, and W. Joseph Manifold, whose terms expire at the annual meeting, have been nominated for election through 2014 for the reasons described below.

Except as otherwise specified in the proxy, proxies will be voted for election of the five nominees. If a nominee becomes unable or unwilling to serve, proxies will be voted for such other person, if any, as shall be designated by the Board of Directors. However, the Corporations management now knows of no reason to anticipate that this will occur. The five nominees for election as directors who receive the greatest number of votes cast will be elected directors. Each of the nominees has agreed to serve as a director if elected.

Nominees for election and current directors are listed below. Also shown for each nominee and each current director is his or her principal occupation for the last five or more years, age and length of service as a director of the Corporation.

The Board of Directors unanimously recommends that shareholders vote FOR the election of each of the five director nominees nominated by the Board of Directors.

Proposal 2-Advisory Vote On Executive Compensation

The compensation of the Corporations principal executive officer, principal financial officer, and three other most highly compensated executive officers (named executive officers) is described below under the headings Compensation Discussion and Analysis and Executive Officers. Shareholders are urged to read these sections of this proxy statement, which discusses the Corporations compensation policies and procedures with respect to its named executive officers.

In accordance with recently adopted changes to Section 14A of the Securities Exchange Act of 1934 (the Exchange Act), shareholders will be asked at the annual meeting to provide their support with respect to the compensation of the Corporations named executive officers by voting on the following advisory, non-binding resolution:

RESOLVED, that the shareholders of Isabella Bank Corporation approve, on an advisory basis, the compensation paid to the Corporations named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, SEC including the Compensation Discussion and Analysis, compensation tables and narrative discussion, for purposes of Section 14A (a) of the Securities Exchange Act of 1934.

This advisory vote, commonly referred to as a say-on-pay advisory vote, is non-binding on the Board of Directors. Although non-binding, the Board of Directors and the Compensation and Human Resource Committee value constructive dialogue on executive compensation and other important governance topics with the Corporations shareholders and encourage all shareholders to vote their shares on this matter. The Board of Directors and the Compensation and Human Resource Committee will review the voting results and take them into consideration when making future decisions regarding executive compensation programs. The Board believes shareholders should consider the following in determining whether to approve this proposal:

The Corporation is not required to provide any severance or termination pay or benefits to any named executive officer;

| | Each member of the Compensation and Human Resource Committee is
independent under the applicable standards of the NASDAQ
Marketplace Rules; |

| | The Compensation and Human Resource Committee with the
assistance of an independent compensation consulting firm

compensation programs against peer companies, the general
marketplace and other industry data points. |

Unless otherwise instructed, validly executed proxies will be voted FOR this resolution.

The Board of Directors unanimously recommends that shareholders vote FOR the nonbinding advisory resolution approving the executive compensation of the Corporations named executive officers.

Proposal 3-Frequency of Advisory Votes On Executive Compensation

In accordance with recently adopted changes to Section 14A of the Exchange Act, the Corporation is providing a shareholder advisory vote to approve the compensation of our named executive officers (the say-on-pay advisory vote in Proposal 2 above) this year and will do so at least once every three years thereafter. Pursuant to recently adopted changes to Section 14A of the Exchange Act, at the 2011Annual Meeting, the Corporation is also asking shareholders to vote on whether future say-on-pay advisory votes on executive compensation should occur every year, every two years or every three years.

After careful consideration, the Board of Directors recommends that future shareholder say-on-pay advisory votes on executive compensation be conducted every three years. Although the Board of Directors recommends a say-on-pay vote every three years, shareholders will be able to specify one of four choices for this proposal on the proxy card: one year, two years, three years or abstain. Shareholders are not voting to approve or disapprove the Board of Directors recommendation.

Although this advisory vote regarding the frequency of say-on-pay votes is non-binding on the Board of Directors, the Board of Directors and the Compensation and Human Resource Committee will review the voting results and take them into consideration when deciding how often to conduct future say-on-pay shareholder advisory votes.

Unless otherwise instructed, validly executed proxies will be voted FOR the Three Year frequency option.

The Board of Directors unanimously recommends that shareholders vote FOR the Three Year frequency option.

Report of the Audit Committee

The Audit Committee oversees the Corporations financial reporting process on behalf of the Board. The 2010 Committee consisted of directors Barnes, Hubscher, LaFramboise, Maness, Manifold and McGuire.

The Audit Committee is responsible for pre-approving all auditing services and permitted non-audit services for the Corporation by its 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, except as noted below. 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 of Directors.

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 quality, not just 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, managements assertion on the design and effectiveness of the Corporations internal control over financial reporting as of December 31, 2010.

The Audit Committee reviewed with the Corporations 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 quality, not just the acceptability, of the Corporations 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), including those described in AU Section 380 Communication 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 accountants required by PCAOB Rule 3526, Communication with Audit Committees Concerning Independence, as may be modified or supplemented, and has discussed with the independent accountant the independent accountants independence.

The Audit Committee discussed with the Corporations 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 the Corporations internal controls and the overall quality of the Corporations financial reporting process. The Audit Committee held six meetings during 2010, and all committee members attended 75% or more of the meetings.

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, 2010 for filing with the Securities and Exchange Commission.

Compensation Discussion and Analysis

The Compensation and Human Resource Committee (the Committee) is responsible for the compensation and benefits for the Chief Executive Officer, President, and executive officers of the Corporation. The Committee evaluates and approves the executive officer and senior management compensation plans, policies and programs of the Corporation and its affiliates. The Chief Executive Officer, Richard J. Barz, conducts annual performance reviews for Named Executive Officers, excluding himself. Mr. Barz recommends an appropriate salary to the Committee based on the performance review and the officers years of service along with competitive market data.

Compensation Objectives

The Committee considers asset growth with the safety and soundness objectives and earnings per share to be the primary ratios in measuring financial performance. The Corporations philosophy is to maximize long-term return to shareholders consistent with safe and sound banking practices, while maintaining the commitment to superior customer and community service. The Corporation believes that the performance of executive officers in managing the business should be the basis for determining overall compensation. Consideration is also given to overall economic conditions and current competitive forces in the market place. The objectives of the Committee are to effectively balance salaries and potential compensation to an officers individual management responsibilities and encourage them to realize their potential for future contributions to the Corporation. The objectives are designed to attract and retain high performing executive officers who will lead the Corporation while attaining the Corporations earnings and performance goals.

What the Compensation Programs are Designed to Reward

The Corporations compensation programs are designed to reward dedicated and conscientious employment with the Corporation, loyalty in terms of continued employment, attainment of job related goals and overall profitability of the Corporation. In measuring an executive officers contributions to the Corporation, the Committee considers numerous factors including, among other things, the Corporations growth in terms of asset size and increase in earnings per share. In rewarding loyalty and long-term service, the Corporation provides attractive retirement benefits.

Review of Risks Associated with Compensation Plans

Based on an analysis conducted by management and reviewed by the Committee, management does not believe that the Corporations compensation programs for employees are reasonably likely to have a material short or long term adverse effect on the Corporations Results of Operation.

Use of Consultants

In 2010, the Committee directly engaged the services of Blanchard Chase, an outside compensation consulting firm, to assist with a total compensation review for the top two executive officers of the Corporation (CEO and President). Blanchard Chase is an independent consulting firm and does not perform any additional services for the Corporation or senior management. In addition, Blanchard Chase does not have any other personal or business relationships with any Board member or any officer of the Corporation. The Committee is continuing to work with Blanchard Chase on proxy support in 2011. During 2009, the Committee did not employ any services of outside compensation or benefit consultants to assist it in compensation-related initiatives.

Elements of Compensation

The Corporations executive compensation program has consisted primarily of base salary and benefits, annual cash bonus incentives, director fees for insider directors, and participation in the Corporations retirement plans.

Why Each of the Elements of Compensation is Chosen

Base Salary and Benefits are set to provide competitive levels of compensation to attract and retain officers with strong motivated leadership. Each officers performance, current compensation, and responsibilities within the Corporation are considered by the Committee when establishing base salaries. The Corporation also believes it is best to pay sufficient base salary because it believes an over-reliance on equity incentive compensation could

XBRL Paragraph Pagebreak XBRL Pagebreak Begin

END PAGE WIDTH PAGEBREAK

BEGIN PAGE WIDTH XBRL Pagebreak End

potentially skew incentives toward short-term maximization of shareholder value as opposed to building long-term shareholder value. Base salary encourages management to operate the Corporation in a safe and sound manner even when incentive goals may prove unattainable.

Annual Performance Incentives are used to reward executive officers for the Corporations overall financial performance. This element of the Corporations compensation programs is included in the overall compensation in order to reward employees above and beyond their base salaries when the Corporations performance and profitability exceed established annual targets. The inclusion of a modest incentive compensation encourages management to be more creative, diligent and exhaustive in managing the Corporation to achieve specific financial goals without incurring inordinate risks.

Performance incentives paid under the Executive Incentive Plan in 2010 were determined by reference to seven performance measures that related to services performed in 2009. The maximum award that may be granted under the Executive Incentive Plan to each eligible employee equals 10% of the employees base salary (the Maximum Award). The payment of 35% of the Maximum Award was conditioned on the eligible employee accomplishing personal performance goals that were established by such employees supervisor as part of the employees annual performance review. Each of the employees who were eligible to participate in the Executive Incentive Plan in 2009 accomplished his or her personal performance goals and was accordingly paid 35% of the 2009 Maximum Award. The payment of the remaining 65% of the Maximum Award was conditioned on the achievement of Corporation-wide targets in the following six categories: (1) earnings per share (weighted 40%); (2) net operating expenses to average assets (weighted 15%); (3) Fully Taxable Equivalent FTE net interest margin, excluding loan fees (weighted 15%); (4) in-market deposit growth (weighted 10%); (5) loan growth (weighted 10%); and (6) exceeding peer group return on average assets (weighted 10%). The following chart provides the 2009 target for each of the foregoing targets that were used to determine bonus awards that were paid in 2010, as well as the performance obtained for each target.

Executive Incentive Plan

Exceeding peer group return
on average assets	−0.26 %	−0.25 %	−0.25 %	−0.24 %	0.91 %

Retirement Plans. The Corporations retirement plans are designed to assist executives in providing themselves with a financially secure retirement. The retirement plans include: a frozen defined benefit pension plan; a 401(k) plan; and a non-leveraged employee stock ownership plan (ESOP), which is frozen to new participants; and a retirement bonus plan.

How the Corporation Chose Amounts for Each Element

The Committees approach to determining the annual base salary of executive officers is to offer competitive salaries in comparison with other comparable financial institutions. The Committee utilizes both an independent compensation consultant, Blanchard Chase and a survey prepared by the Michigan Bankers Association of similar sized Michigan based institutions. The independent compensation consultant established a benchmark peer group of 20 mid-west financial institutions in non urban areas whose average assets size, number of branch locations, return on average assets and nonperforming assets that were comparable to Isabella Bank Corporation. The Michigan Bankers Association 2010 compensation survey was based on the compensation information provided by these organizations for 2009. Specific factors used to decide where an executive officers salary should be within the established range include the historical financial performance, financial performance outlook, years of service, and job performance.

BEGIN PAGE WIDTH XBRL Pagebreak End

The annual performance incentive is based on the achievement of goals set for each individual. An analysis is conducted by the Chief Executive Officer. The Chief Executive Officer makes a recommendation to the Committee for the appropriate amount for each individual executive officer. The Committee reviews, modifies if necessary, and approves the recommendations of the Chief Executive Officer. The Committee reviews the performance of the Chief Executive Officer. The Committee uses the following factors as quantitative measures of corporate performance in determining annual cash bonus amounts to be paid:

	Peer group financial performance compensation
	1 and 5 year shareholder returns
	Earnings per share and earnings per share growth
	Budgeted as compared to actual annual operating performance
	Community and industry involvement
	Results of audit and regulatory exams
	Other strategic goals as established by the board of directors

While no particular weight is given to any specific factor, the Committee gives at least equal weight to the subjective analyses as described above.

Total compensation in 2010 was based on the Committee targeting its Chief Executive Officers and President & Chief Financial Officers compensation to approximate the median of the range provided by the independent compensation consultant. Compensation for other named executive officers was based on the ranges provide by the Michigan Bankers Association surveys.

Retirement plans. The Corporation has a 401(k) plan in which substantially all employees are eligible to participate. Employees may contribute up to 50% of their compensation subject to certain limits based on federal tax laws. As a result of the curtailment of the defined benefit plan noted below, the Corporation increased the contributions to the 401(k) plan effective January 1, 2007. The Corporation makes a annual 3.0% safe harbor contribution for all eligible employees and matching contributions equal to 50% of the first 4.0% of an employees compensation contributed to the Plan during the year. Employees are 100% vested in the safe harbor contributions and are 0% vested through their first two years of employment and are 100% vested after 6 years through a laddered vesting schedule of service for matching contributions.

The Corporation maintains a non-leveraged employee stock ownership plan (ESOP) which covers substantially all of its employees. The plan was frozen effective December 31, 2006 to new participants. Contributions to the plan are discretionary and approved by the Board of Directors.

The retirement bonus plan is a nonqualified plan of deferred compensation benefits for eligible employees effective January 1, 2007. An initial amount has been credited for each eligible employee as of January 1, 2007. Subsequent amounts will be credited on each allocation date thereafter as defined in the plan. The amount of the initial allocation and the annual allocation are determined pursuant to the payment schedule adopted at the sole and exclusive discretion of the Board of Directors, as set forth in the plan.

In December 2006, the Board of Directors voted to curtail the defined benefit plan effective March 1, 2007. The effect of the curtailment was recognized in the first quarter of 2007 and the current participants accrued benefits were frozen as of March 1, 2007. Participation in the plan was limited to eligible employees as of December 31, 2006.

Other Benefits and Perquisites. Executive officers are eligible for all of the benefits made available to full-time employees of the Corporation (such as the 401(k) plan, employee stock purchase plan, health insurance, group term life insurance and disability insurance) on the same basis as other full-time employees and are subject to the same sick leave and other employee policies. The Corporation also provides its executive officers with certain additional benefits and perquisites, which it believes are appropriate in order to attract and retain the proper quality of talent for these positions and to recognize that similar executive benefits and perquisites are commonly offered by comparable financial institutions.

XBRL Pagebreak Begin

END PAGE WIDTH PAGEBREAK

BEGIN PAGE WIDTH XBRL Pagebreak End

A description and the cost to the Corporation of these perquisites are included in footnote two in the Summary Compensation Table appearing on page 14.

The Corporation believes that benefits and perquisites provided to its executive officers in 2010 represented a reasonable percentage of each executives total compensation package and was not inconsistent, in the aggregate, with perquisites provided to executive officers of comparable competing financial institutions.

The Corporation maintains a plan for qualified officers to provide death benefits to each participant. Insurance policies, designed primarily to fund death benefits, have been purchased on the life of each participant with the Corporation as the sole owner and beneficiary of the policies.

How Elements Fit into Overall Compensation Objectives

The elements of the Corporations compensation are structured to reward past and current performance, continued service and motivate its leaders to excel in the future. The Corporations salary compensation has generally been used to retain and attract motivated leadership. The Corporation intends to continually ensure salaries are sufficient to attract and retain exceptional officers. The Corporations cash bonus incentive rewards current performance based upon personal and corporate goals and targets. The Corporation offers the Isabella Bank Corporation and Related Companies Deferred Compensation Plan for Directors (the Directors Plan) to motivate its eligible officers to enhance value for shareholders by aligning the interests of management with those of its shareholders.

As part of its goal of attracting and retaining quality team members, the Corporation has developed competitive employee benefit plans. Management feels that the combination of all of the plans listed above makes the Corporations total compensation packages attractive.

Defined benefit pension plan. The Corporation sponsors the Isabella Bank Corporation Pension Plan, a frozen defined benefit pension plan. In December 2006, the Board of Directors voted to curtail the defined benefit plan effective March 1, 2007. The curtailment froze the current participants accrued benefits as of March 1, 2007 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 participants actual years of service with the Corporation.

Annual contributions are made to the plan as required by accepted actuarial principles, applicable federal tax laws, and expenses of 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, effective through December 31, 2006.

A participant may earn a benefit for up to 35 years of accredited service. Earned benefits are 100 percent 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.

Dennis P. Angner, Richard J. Barz, Timothy M. Miller, and Steven D. Pung are eligible for early retirement under the Isabella Bank Corporation Pension Plan. Under the provisions of the Plan, participants are eligible for early retirement after reaching the age of 55 with at least 5 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. The Corporation sponsors the Isabella Bank Corporation Retirement Bonus Plan. The Retirement Bonus Plan is a nonqualified plan of deferred compensation benefits for eligible employees effective January 1, 2007. This plan is intended to provide eligible employees with additional retirement benefits. To be eligible, the employee needed to be employed by the Corporation on January 1, 2007, and be a participant in the Corporations frozen Executive Supplemental Income Agreement. Participants must also be an officer of the Corporation with at least 10 years of service as of December 31, 2006. The Corporation has sole and exclusive discretion to add new participants to the plan by authorizing such participation pursuant to action of the Corporations Board of Directors.

An initial amount has been credited for each eligible employee as of January 1, 2007. Subsequent amounts shall be credited on each allocation date thereafter as defined in the Plan. The amount of the initial allocation and the

annual allocation shall be determined pursuant to the payment schedule adopted by the sole and exclusive discretion of the Board, as set forth in the Plan.

Dennis P. Angner, Richard J. Barz, Timothy M. Miller, and Steven D. Pung are eligible for early retirement under the Isabella Bank Corporation Retirement Bonus Plan. Under the provisions of the 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.

The directors of the Corporation and its subsidiaries are required to defer at least 25% of their earned board fees into the Directors Plan and may defer up to 100% of their earned fees based on their annual election. These amounts are reflected in the 2010 nonqualified deferred compensation table above. Under the Directors Plan, these deferred fees are converted on a quarterly basis into shares of the Corporations common stock based on the fair market value of shares of the Corporations common stock at that time. Shares credited to a participants account are eligible for stock and cash dividends as payable.

Distribution from the Directors Plan occurs when the participant retires from the Board, attains age 70 or upon the occurrence of certain other events. Distributions must take the form of shares of the Corporations common stock. Any Corporation common stock issued under the Directors Plan will be considered restricted stock under the Securities Act of 1933, as amended.

Potential Payments Upon Termination or Change in Control

The estimated payments payable to each named executive officer upon severance from employment, retirement, termination upon death or disability or termination following a change in control of the Corporation are described below. For all termination scenarios, the amounts assume such termination took place as of December 31, 2010.

Any Severance of Employment

Regardless of the manner in which a named executive officers 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 deferred in the Directors Plan. |
| | Unused vacation pay. |

Retirement

In the event of the retirement of an executive officer, the officer would receive the benefits identified above.

As of December 31, 2010, the named executive officers listed had no unused vacation days.

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 the Corporations life insurance plan or benefits under the Corporations disability plan as appropriate.

In addition to potential payments upon termination available to all employees, the estates for the executive officers listed below would receive the following payments upon death:

	While an — Active	Subsequent to

Steven D. Pung	285,400	142,700
David J. Reetz	247,800	123,900

Change in Control

The Corporation currently does not have a change in control agreement with any of the executive officers; provided, however, pursuant to the Retirement Bonus Plan each participant would become 100% vested in their benefit under the plan if, following a change in control, they voluntarily terminate employment or are terminated without just cause.

The Corporation paid a $14,000 retainer plus $1,350 per board meeting to external directors and a $6,000 retainer plus $1,350 per board meeting to inside directors during 2010. Members of the audit committee were paid $350 per audit committee meeting attended.

Pursuant to the Directors Plan the directors of the Corporation and its subsidiaries are required to defer at least 25% of their earned board fees. Under the Directors Plan, deferred directors fees are converted on a quarterly basis into shares of the Corporations common stock, based on the fair market value of a share of the Corporations

common stock at that time. Shares of stock credited to a participants account are eligible for cash and stock dividends as payable. Directors of the Corporation deferred $419,696 under the Directors Plan in 2010.

Upon a participants attainment of age 70, retirement from the Board, or the occurrence of certain other events, the participant is eligible to receive a lump-sum, in-kind distribution of all of the stock that is then credited to his or her 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.

The Corporation established a Trust effective as of January 1, 2008 to fund the Directors Plan. The Trust is an irrevocable grantor trust to which the Corporation may contribute assets for the limited purpose of funding a nonqualified deferred compensation plan. Although the Corporation may not reach the assets of the Trust for any purpose other than meeting its obligations under the Directors Plan, the assets of the Trust remain subject to the claims of the Corporations creditors. The Corporation may contribute cash or common stock to the Trust from time to time for the sole purpose of funding the Directors Plan. The Trust will use any cash that the Corporation may contribute to purchase shares of the Corporations common stock on the open market through the Corporations brokerage services department.

The Corporation transferred $492,958 to the Trust in 2010, which held 32,686 shares of the Corporations common stock for settlement as of December 31, 2010. As of December 31, 2010, there were 191,977 shares of stock credited to participants accounts, which 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 Trust. All amounts are unsecured claims against the Corporations general assets. The net cost of this benefit to the Corporation was $165,353 in 2010.

Indebtedness of and Transactions with Management

Certain directors and officers of the Corporation and members of their families were loan customers of Isabella Bank, or have been directors or officers of corporations, or partners of partnerships which have had transactions with the Bank. In managements 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.

Independent Registered Public Accounting Firm

The Audit Committee has appointed Rehmann Robson as the independent auditors of the Corporation for the year ending December 31, 2011.

A representative of Rehmann Robson is expected to be present at the Annual Meeting of Shareholders to respond to appropriate questions from shareholders and to make any comments Rehmann believes is appropriate.

Fees for Professional Services Provided by Rehmann Robson P.C.

The following table shows the aggregate fees billed by Rehmann Robson for the audit and other services provided to the Corporation for 2010 and 2009.

	2010	2009
Audit fees	$ 252,163	$ 291,497
Audit related fees	39,089	40,135
Tax fees	24,730	39,784
Other professional services fees
Total	$ 315,982	$ 371,416

The audit fees were for performing the integrated audit of the Corporations consolidated annual financial statements and the audit of internal control over financial reporting related to the Federal Deposit Insurance Corporation Improvement Act, review of interim quarterly financial statements included in the Corporations Forms 10-Q, and services that are normally provided by Rehmann Robson in connection with statutory and regulatory filings or engagements. The decline in audit fees from 2009 to 2010 is primarily related to the Corporations continued improvement in financial reporting and SOX 404 processes.

The audit related fees are typically for various discussions related to the adoption and interpretation of new accounting pronouncements. Also included are fees for auditing of the Corporations employee benefit plans.

The tax fees were for the preparation of the Corporations and its subsidiaries state and federal tax returns and for consultation with the Corporation on various tax matters. During 2009 tax fees also included consulting related to the then new State of Michigan Business Tax (MBT).

The Audit Committee has considered whether the services provided by Rehmann Robson, P.C. other than the audit fees, are compatible with maintaining Rehmann Robson, P.C.s independence and believes that the other services provided are compatible.

Pre-Approval Policies and Procedures

All audit and non-audit services over $5,000 to be performed by Rehmann Robson 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 services. As permitted by the SECs 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

XBRL Paragraph Pagebreak XBRL Pagebreak Begin

BEGIN PAGE WIDTH XBRL Pagebreak End

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 professional services, none were billed pursuant to these provisions in 2010 and 2009 without pre-approval as required under the Corporations policies.

Shareholder Proposals

Any proposals which shareholders of the Corporation intend to present at the next annual meeting of the Corporation must be received before December 9, 2011 to be considered for inclusion in the Corporations proxy statement and proxy for that meeting. Proposals should be made in accordance with Securities and Exchange Commission Rule 14a-8.

Directors Attendance at the Annual Meeting of Shareholders

The Corporations directors are encouraged to attend the annual meeting of shareholders. At the 2010 annual meeting, all directors were in attendance.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires the Corporations directors and certain officers and persons who own more than ten percent of the Corporations common stock, to file with the SEC initial reports of ownership and reports of changes in ownership of the Corporations common stock. These officers, directors, and greater than ten percent shareholders are required by SEC regulation to furnish the Corporation with copies of these reports.

To the Corporations knowledge, based solely on review of the copies of such reports furnished to the Corporation, during the year ended December 31, 2010 all Section 16(a) filing requirements were satisfied, with respect to the applicable officers, directors, and greater than 10 percent beneficial owners.

Other Matters

The cost of soliciting proxies will be borne by the Corporation. In addition to solicitation by mail, officers and other employees of the Corporation may solicit proxies by telephone or in person, without compensation other than their regular compensation.

As to Other Business Which May Come Before the Meeting

Management of the Corporation does not intend to bring any other business before the meeting for action. However, if any other business should be presented for action, it is the intention of the persons named in the enclosed form of proxy to vote in accordance with their judgment on such business.

By order of the Board of Directors

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Shareholders and Board of Directors

Isabella Bank Corporation

Mount Pleasant, Michigan

We have audited the accompanying consolidated balance sheets of Isabella Bank Corporation as of December 31, 2010 and 2009, and the related consolidated statements of changes in shareholders equity, income, comprehensive income, and cash flows for each of the years in the three-year period ended December 31, 2010. We also have audited Isabella Bank Corporations internal control over financial reporting as of December 31, 2010, based on criteria established in the Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Isabella Bank Corporations management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the effectiveness of Isabella Bank Corporation s internal control over financial reporting, based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material misstatement exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. We believe that our audits provide a reasonable basis for our opinion.

A corporations internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. A corporations internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the corporation; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the corporation are being made only in accordance with authorizations of management and directors of the corporation; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the corporations assets that could have a material effect on the consolidated financial statements.

As discussed in Note 1 to the consolidated financial statements, effective January 1, 2008, the Corporation adopted ASC Topic 715, Compensation Retirement Benefits .

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Isabella Bank Corporation as of December 31, 2010 and 2009, and the consolidated results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2010 in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion Isabella Bank Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the criteria established in the Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations (COSO) of the Treadway Commission.

NOTE 1 Nature of Operations and Summary of Significant Accounting Policies

XBRL,body

Basis of Presentation and Consolidation:

The consolidated financial statements include the accounts of Isabella Bank Corporation (the Corporation), a financial services holding company, and its wholly owned subsidiaries, Isabella Bank (the Bank), Financial Group Information Services, and IB&T Employee Leasing, LLC. All intercompany balances and accounts have been eliminated in consolidation.

Nature of Operations:

Isabella Bank Corporation is a financial services holding company offering a wide array of financial products and services in several mid-Michigan counties. Its banking subsidiary, Isabella Bank, offers banking services through 25 locations, 24 hour banking services locally and nationally through shared automatic teller machines, 24 hour online banking, and direct deposits to businesses, institutions, and individuals. Lending services offered include commercial loans, agricultural loans, residential real estate loans, consumer loans, student loans, and credit cards. Deposit services include interest and noninterest bearing checking accounts, savings accounts, money market accounts, and certificates of deposit. Other related financial products include trust and investment services, safe deposit box rentals, and credit life insurance. Active competition, principally from other commercial banks, savings banks and credit unions, exists in all of the Corporations principal markets. The Corporations results of operations can be significantly affected by changes in interest rates or changes in the local economic environment.

Financial Group Information Services provides information technology services to Isabella Bank Corporation and its subsidiaries.

IB&T Employee Leasing provides payroll services, benefit administration, and other human resource services to Isabella Bank Corporation and its subsidiaries.

Use of Estimates:

In preparing consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and reported amounts of revenues and expenses during the reporting year. Actual results could differ from those estimates.

Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the fair value of certain available-for-sale investment securities, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, valuation of goodwill and other intangible assets, and determinations of assumptions in accounting for the defined benefit pension plan. In connection with the determination of the allowance for loan losses and the carrying value of foreclosed real estate, management obtains independent appraisals for significant properties.

Fair Value Measurements:

Fair value refers to the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants in the market in which the reporting entity transacts such sales or transfers based on the assumptions market participants would use when pricing an asset or liability. Assumptions are developed based on prioritizing information within a fair value hierarchy that gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data, such as the reporting entitys own data. The Corporation may choose to measure eligible items at fair value at specified election dates. Unrealized gains and losses on items for which the fair value measurement option has been elected are reported in earnings at each subsequent reporting date. The fair value option (i) may be applied instrument by instrument, with certain exceptions, allowing the Corporation to record identical financial assets and liabilities at fair value or by another

XBRL Pagebreak End

measurement basis permitted under generally accepted accounting principles, (ii) is irrevocable (unless a new election date occurs) and (iii) is applied only to entire instruments and not to portions of instruments.

For assets and liabilities recorded at fair value, it is the Corporations policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements for those financial instruments for which there is an active market. In cases where the market for a financial asset or liability is not active, the Corporation includes appropriate risk adjustments that market participants would make for nonperformance and liquidity risks when developing fair value measurements. Fair value measurements for assets and liabilities for which limited or no observable market data exists are accordingly based primarily upon estimates, are often calculated based on the economic and competitive environment, the characteristics of the asset or liability and other factors. Therefore, the results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset or liability. Additionally, there may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values.

The Corporation utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Investment securities available-for-sale, trading securities, and certain liabilities are recorded at fair value on a recurring basis. Additionally, from time to time, the Corporation may be required to record other assets at fair value on a nonrecurring basis, such as mortgage loans available-for-sale, impaired loans, foreclosed assets, originated mortgage servicing rights, goodwill, 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.

Fair Value Hierarchy

Under fair value measurement and disclosure authoritative guidance, the Corporation groups 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 assets or liabilitys 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.

For a further discussion of fair value considerations, refer to Notes 19 to the consolidated financial statements.

Significant Group Concentrations of Credit Risk:

Most of the Corporations activities conducted are with customers located within the central Michigan area. A significant amount of its outstanding loans are secured by commercial and residential real estate. Other than these types of loans, there is no significant concentration to any other industry or any one customer.

Cash and Cash Equivalents:

For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and balances due from banks, federal funds sold, and other deposit accounts. Generally, federal funds sold are for a one day

period. The Corporation maintains deposit accounts in various financial institutions which generally exceed federally insured limits or are not insured. Management does not believe the Company is exposed to any significant interest, credit or other financial risk as a result of these deposits.

Certificates of Deposit Held in Other Financial Institutions:

Certificates of deposits held in other financial institutions consist of interest bearing certificates of deposit that mature within 3 years and are carried at cost.

Trading Securities:

The Corporation engages in trading activities of its own accounts. Securities that are held principally for resale in the near term are recorded in the trading assets account at fair value with changes in fair value recorded in noninterest income. Interest income is included in net interest income.

Available-For-Sale Investment Securities:

All purchases of investment securities are generally classified as available-for-sale. However, classification of investment securities as either held to maturity or trading may be elected by management of the Corporation. Securities classified as available-for-sale are recorded at fair value, with unrealized gains and losses, net of the effect of deferred income taxes, excluded from earnings and reported in other comprehensive income. Auction rate money market preferred securities and preferred stocks are considered equity securities for federal income tax purposes, as such, no estimated federal income tax impact is expected or recorded. Auction rate money market preferred securities and preferred stock are recorded at fair value, with unrealized gains and losses, considered not other-than-temporary, excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Realized gains and losses on the sale of available-for-sale investment securities are determined using the specific identification method.

Investment securities are reviewed quarterly for possible other-than-temporary impairment (OTTI). In determining whether an other-than-temporary impairment exists for debt securities, management must assert that: (a) it does not have the intent to sell the security; and (b) it is more likely than not it will not have to sell the security before recovery of its cost basis. If these conditions are not met, the Corporation must recognize an other-than-temporary impairment charge through earnings for the difference between the debt securitys amortized cost basis and its fair value, and such amount is included in noninterest income. For debt securities that do not meet the above criteria, and the Corporation does not expect to recover the securitys amortized cost basis, the security is considered other-than-temporarily impaired. For these debt securities, the Corporation separates the total impairment into the credit risk loss component and the amount of the loss related to market and other risk factors. In order to determine the amount of the credit loss for a debt security, the Corporation calculates the recovery value by performing a discounted cash flow analysis based on the current cash flows and future cash flows management expects to recover. The amount of the total other-than-temporary impairment related to the credit risk is recognized in earnings and is included in noninterest income. The amount of the total other-than-temporary impairment related to other risk factors is recognized as a component of other comprehensive income. For debt securities that have recognized an other-than-temporary impairment through earnings, if through subsequent evaluation there is a significant increase in the cash flow expected, the difference between the amortized cost basis and the cash flows expected to be collected is accreted as interest income.

Available-for-sale equity securities are reviewed for other-than-temporary impairment at each reporting date. This evaluation considers a number of factors including, but not limited to, the length of time and extent to which the fair value has been less than cost, the financial condition and near term prospects of the issuer, and managements ability and intent to hold the securities until fair value recovers. If it is determined that management does not have the ability and intent to hold the securities until recovery or that there are conditions that indicate that a security may

not recover in value then the difference between the fair value and the cost of the security is recognized in earnings and is included in noninterest income. No such losses were recognized in 2010, 2009, or 2008.

Loans:

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balance adjusted for any charge-offs, the allowance for loans losses, and any deferred fees or costs on originated loans. Interest income on loans 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 constant yield method.

The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days or more past due unless the credit is well-secured and in the process of collection. Credit card loans and other personal loans are typically charged off no later than 180 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful.

For loans that are placed on non-accrual status or charged off, all interest accrued in the current calendar year, but not collected, is reversed against interest income while interest accrued in prior calendar years, but not collected is charged against the allowance for loan losses. The interest on these loans is accounted for on the cash-basis, until qualifying for return to accrual status. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. For impaired loans not classified as nonaccrual, interest income continues to be accrued over the term of the loan based on the principal amount outstanding.

Allowance for Loan Losses:

The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a regular basis by management and is based upon managements periodic review of the collectibility of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrowers 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 allowance consists of specific, general and unallocated components. The specific component relates to loans that are deemed to be impaired. For such loans that are also analyzed for specific allowance allocations, an allowance is established when the discounted cash flows or collateral value or observable market price of the impaired loan is lower than the carrying value of that loan. The general component covers non classified loans and is based on historical loss experience. An unallocated component is maintained to cover uncertainties that management believes affect its estimate of probable losses based on qualitative factors. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.

Loans may be classified as impaired if they meet one or more of the following criteria:

There has been a chargeoff of its principal balance;
The loan has been classified as a troubled debt restructuring; or
The loan is in nonaccrual status.

Impairment is measured on a loan by loan basis for commercial and commercial real estate loans by either the present value of expected future cash flows discounted at the loans effective interest rate, the loans obtainable market price, or the fair value of the collateral, less cost to sell, if the loan is collateral dependent.

Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Corporation does not separately identify individual consumer loans for impairment allocations and related disclosures.

Loans Held for Sale:

Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value as determined by aggregating outstanding commitments from investors or current investor yield requirements. Net unrealized losses, if any, are recognized through a valuation allowance of which the provision is accounted for in other noninterest expenses in the consolidated statements of income.

Mortgage loans held for sale are sold with the mortgage servicing rights retained by the Corporation. The carrying value of mortgage loans sold is reduced by the cost allocated to the associated mortgage servicing rights. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loans sold.

Transfers of Financial Assets:

Transfers of financial assets, including sold mortgage loans and mortgage loans held for sale, as described above, and participation loans are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is determined to be surrendered when 1) the assets have been legally isolated from the Corporation, 2) the transferee obtains the right (free of conditions that constrain it from taking advantage of the right) to pledge or exchange the transferred assets and 3) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Other than servicing, as disclosed in Note 5, the Corporation has no substantive continuing involvement related to these loans. Servicing fee earned on such loans was $760, $724, and $627 for 2010, 2009, and 2008, respectively, and is included in other noninterest income.

Servicing:

Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of financial assets. The Corporation has no purchased servicing rights. For sales of mortgage loans, a portion of the cost of originating the loan is allocated to the servicing right based on relative fair value. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses.

Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights into tranches based on predominant risk characteristics, such as interest rate, loan type, and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranche. If the Corporation later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the valuation allowance may be recorded as an increase to income. Capitalized servicing rights are reported in other assets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets.

Servicing fee income is recorded for fees earned for servicing loans for others. The fees are based on a contractual percentage of the outstanding principal; or a fixed amount per loan and are recorded as income when earned.

Loans Acquired Through Transfer:

Authoritative accounting guidance related to acquired loans requires that a valuation allowance for loans acquired in a transfer, including in a business combination, reflect only losses incurred after acquisition, and should not be recorded at acquisition. This standard applies to any loan acquired in a transfer that shows evidence of credit quality deterioration since it was originated.

Foreclosed Assets:

Assets acquired through, or in lieu, of loan foreclosure are held for sale and are initially recorded at the lower of the Corporations carrying amount or fair value less estimated selling costs at the date of transfer, establishing a new cost basis. Any write downs based on the assets fair value at the date of acquisition are charged to the allowance for loan losses. After foreclosure, property held for sale is carried at the lower of the new cost basis or fair value less costs to sell. Impairment losses on property to be held and used are measured at the amount by which the carrying amount of property exceeds its fair value. Costs relating to holding these assets are expensed as incurred. Valuations are periodically performed by management, and any subsequent write-downs are recorded as a charge to operations, if necessary, to reduce the carrying value of a property to the lower of the Corporations carrying amount or fair value less costs to sell. Foreclosed assets of $2,067 and $1,157 are included in Other Assets on the accompanying consolidated balance sheets.

Premises and Equipment:

Land is carried at cost. Buildings and equipment are carried at cost, less accumulated depreciation which is computed principally by the straight-line method based upon the estimated useful lives of the related assets, which range from 3 to 40 years. Major improvements are capitalized and appropriately amortized based upon the useful lives of the related assets or the expected terms of the leases, if shorter, using the straight-line method. Maintenance, repairs and minor alterations are charged to current operations as expenditures occur. Management annually reviews these assets to determine whether carrying values have been impaired.

Fdic Insurance Premium:

In 2009, the Corporation was required to prepay quarterly FDIC risk-based assessments for the fourth quarter of 2009 and each of the quarters in the years ending December 31, 2010, 2011 and 2012. The assessments for 2010 through 2012, which had a carrying balance of $3,586 and $4,737 as of December 31, 2010 and 2009, respectively, have been recorded as a prepaid asset in the accompanying consolidated balance sheets in Other Assets, and will be expensed on a ratable basis quarterly through December 31, 2012.

Equity Securities Without Readily Determinable Fair Values:

Included in equity securities without readily determinable fair values are restricted securities, which are carried at cost, and investments in nonconsolidated entities accounted for under the equity method of accounting.

Stock Compensation Plans:

At December 31, 2010, the Isabella Bank Corporation and Related Companies Deferred Compensation Plan for Directors (the Directors Plan) had 224,663 shares to be issued to participants, for which an associated grantor trust (Rabbi Trust) held 32,686 shares. The Corporation had 216,905 shares to be issued in 2009, with 30,626 shares held in the Rabbi Trust. Compensation costs relating to share based payment transactions are recognized in the consolidated financial statements and the cost is measured based on the fair value of the equity or liability instruments issued. The Corporation has no other share based compensation plans.

Corporate Owned Life Insurance:

The Corporation has purchased life insurance policies on key members of management. In the event of death of one of these individuals, the Corporation would receive a specified cash payment equal to the face value of the policy. Such policies are recorded at their cash surrender value, or the amount that can be realized on the balance sheet dates. Increases in cash surrender value in excess of single premiums paid are reported as Other Noninterest Income.

ASC Topic 715 was amended to require that the Corporation recognize a liability for any post retirement benefits provided by the Corporation, beginning January 1, 2008. As a result of the adoption of the new authoritative guidance, the Corporation recognized a liability of $1,571 as of January 1, 2008. As of December 31, 2010 and 2009, the present value of the post retirement benefits promised by the Corporation to the covered employees was estimated to be $2,573 and $2,505, respectively, and is included in Accrued Interest and Other Liabilities on the consolidated balance sheets. The periodic policy maintenance costs were $68 and $45 for 2010 and 2009, respectively.

Acquisition Intangibles and Goodwill:

The Corporation previously acquired branch facilities and related deposits in business combinations accounted for as a purchase. The acquisitions included amounts related to the valuation of customer deposit relationships (core deposit intangibles). Core deposit intangibles arising from acquisitions are included in Other Assets and are being amortized over their estimated lives. Goodwill, which is included in Other Assets, represents the excess of purchase price over identifiable assets, is not amortized but is evaluated for impairment at least annually, or on an interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below the carrying value.

Off Balance Sheet Credit Related Financial Instruments:

In the ordinary course of business, the Corporation has entered into commitments to extend credit, including commitments under credit card arrangements, home equity lines of credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded only when funded.

Federal Income Taxes:

Deferred income tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax assets or liability is determined based on the tax effects of the temporary differences between the book and tax bases on the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. Valuations allowances are established, where necessary, to reduce deferred tax assets to the amount expected to be realized. Income tax expense is the tax payable or refundable for the year plus or minus the change during the year in deferred tax assets and liabilities.

The Corporation analyzes its filing positions in the jurisdictions where it is required to file income tax returns, as well as all open tax years in these jurisdictions. The Corporation has also elected to retain its existing accounting policy with respect to the treatment of interest and penalties attributable to income taxes, and continues to reflect any charges for such, to the extent they arise, as a component of its noninterest expenses

Marketing Costs:

Marketing costs are expensed as incurred (see Note 10).

Computation of Earnings Per Share:

Basic earnings per share represents income available to common stockholders divided by the weighted average number of common shares issued during the period. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from the assumed issuance. Potential common shares that may be issued by the Corporation relate solely to outstanding shares in the Corporations Directors Plan (see Note 16).

Earnings per common share have been computed based on the following:

	2010	2009	2008

within pools are not to be removed from the pool solely as a result of modifications to the loan (including troubled debt restructurings). The new guidance was effective for interim and annual periods ending on or after July 15, 2010 and did not have a significant impact on the Corporations consolidated financial statements.

In July 2010, ASC Topic 310 was amended by ASU No. 2010-20, Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses to provide financial statement users greater transparency about the Corporations allowance for loan losses and the credit quality of its financing receivables. Existing disclosures are amended that required the Corporation to provide the following disclosure about its loan portfolio on a disaggregated basis: (1) a rollforward schedule of the allowance for loan losses from the beginning of the reporting period to the end of a reporting period on a portfolio segment basis, with the ending balance further disaggregated on the basis of the impairment method, (2) for each disaggregated ending balance in item (1), the related recorded investment in loans, (3) the nonaccrual status of loans by class of loans, and (4) impaired loans by class of loans.

The amendments in this update required the Corporation to provide the following additional disclosures about its loans: (1) credit quality indicators of financing receivables at the end of the reporting period by class of loans, (2) the aging of past due loans at the end of the reporting period by class of loans, (3) the nature and extent of troubled debt restructurings that occurred during the period by class of loans and their effect on the allowance for loan losses, (4) the nature and extent of financing receivables modified within the previous 12 months that defaulted during the period by class of financing receivables and their effect on the allowance for loan losses and (5) significant purchases and sales of loans during the period disaggregated by portfolio segment. The new disclosures as of the end of a reporting period were effective for interim and annual reporting periods ending on or after December 15, 2010, with the exception of the new disclosures related to troubled debt restructurings which are not required to be reported until the second quarter of 2011. The new disclosures about activity that occurs during a reporting period are effective for interim and annual reporting periods beginning on or after December 15, 2010. The new guidance has significantly expanded the Corporations consolidated financial statement disclosures. (See Note 4)

FASB ASC Topic 350, Intangibles Goodwill and Other. In December 2010, ASC Topic 350 was amended by ASU No. 2010-28, When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts (a consensus of the FASB Emerging Issues Task Force) , to address questions related to the testing for goodwill impairments for entities with goodwill with zero or negative carrying amounts. The new guidance is effective for interim and annual periods beginning after December 15, 2010 and is not anticipated to have any impact on the Corporations consolidated financial statements.

FASB ASC Topic 715, Compensation Retirement Benefits. In January 2010, ASC Topic 715 was amended by ASU No. 2010-06, Improving Disclosures about Fair Value Measurements , to change the terminology for major categories of assets to classes of assets to correspond with the amendments to ASC Topic 820 (see below). The new guidance was effective for interim and annual periods ending on or after January 1, 2010 and had no impact on the Corporations consolidated financial statements.

FASB ASC Topic 805, Business Combinations. In December 2010, ASC Topic 805 was amended by ASU No. 2010-29, Disclosure of Supplementary Pro Forma Information for Business Combinations (a consensus of the FASB Emerging Issues Task Force , to address diversity in practice about the interpretation of the pro forma revenue and earnings disclosure requirements for business combinations. The new guidance is effective for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period on or after December 15, 2010 and is not anticipated to impact the Corporations consolidated financial statements.

FASB ASC Topic 810, Consolidation. New authoritative accounting guidance under ASC Topic 810 amends prior guidance to change how a company determines when an entity that is insufficiently capitalized or is not controlled through voting (or similar rights) should be consolidated. The determination of whether a company is required to consolidate an entity is based on, among other factors, an entitys purpose and design and a companys ability to direct the activities of the entity that most significantly impact the entitys economic performance. The new authoritative accounting guidance requires additional disclosures about the reporting entitys involvement with

variable interest entities and any significant changes in risk exposure due to that involvement as well as its affect on the entitys financial statements. The new authoritative accounting guidance under ASC Topic 810 was effective January 1, 2010 and had no impact on the Corporations consolidated financial statements.

FASB ASC Topic 820, Fair Value Measurements and Disclosures. In January 2010, ASC Topic 820 was amended by ASU No. 2010-06, to add new disclosures for: (1) significant transfers in and out of Level 1 and Level 2 fair value measurements and the reasons for the transfers and (2) presenting separately information about purchases, sales, issuances and settlements for Level 3 fair value instruments (as opposed to reporting activity as net).

ASU No. 2010-06 also clarifies existing disclosures by requiring reporting entities to provide fair value measurement disclosures for each class of assets and liabilities and to provide disclosures about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements.

The new authoritative guidance was effective for interim and annual reporting periods beginning January 1, 2010 except for the disclosures about purchases, sales, issuances and settlements in the rollforward of activity in Level 3 fair value measurements, which will be effective January 1, 2011. The new guidance did not, and is not anticipated to, have a significant impact on the Corporations consolidated financial statements.

FASB ASC Topic 860, Transfers and Servicing. New authoritative accounting guidance under ASC Topic 860 amends prior accounting guidance to enhance reporting about transfers of financial assets, including securitizations, and where companies have continuing exposure to the risks related to transferred financial assets. The new authoritative accounting guidance eliminates the concept of a qualifying special purpose entity and changes the requirements for derecognizing financial assets. The new authoritative accounting guidance also requires additional disclosures about all continuing involvements with transferred financial assets including information about gains and losses resulting from transfers during the period. The new authoritative accounting guidance under ASC Topic 860 was effective January 1, 2010 and had no significant impact on the Corporations consolidated financial statements.

The Corporation invested $11,000 in auction rate money market preferred investment security instruments, which are classified as available-for-sale securities and reflected at estimated fair value. Due to credit market uncertainty, the trading for these securities has been limited. As a result of the limited trading of these securities, $7,800 converted to preferred stock with debt like characteristics in 2009.

Due to the limited trading activity of these securities, the fair values were estimated utilizing a discounted cash flow analysis as of December 31, 2010 and December 31, 2009. These analyses considered creditworthiness of the counterparty, the timing of expected future cash flows, and the current volume of trading activity. As of December 31, 2010, the Corporation held an auction rate money market preferred security and preferred stock which declined in fair value as a result of the securities interest rates, they are currently lower than the offering rates of securities with similar characteristics. Despite the limited trading of these securities, management has determined that any declines in the fair value of these securities are the result of changes in interest rates and not risks related to the underlying credit quality of the security. Additionally, none of these securities are deemed to be below investment grade, and management does not intend to sell the securities in an unrealized loss position, and it is more likely than not that the Corporation will not have to sell the securities before recovery of their cost basis. As a result, the Corporation has not recognized an other-than-temporary impairment related to these declines in fair value.

As of December 31, 2010 and December 31, 2009, management conducted an analysis to determine whether all securities currently in an unrealized loss position, including auction rate money market preferred securities and preferred stocks, should be considered other-than-temporarily-impaired (OTTI). 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 that the issuer will be unable to pay the amount
when due? |
| | Is it more likely than not that the Corporation will not have to
sell the security before recovery of its cost basis? |
| | Has the duration of the investment been extended? |

Based on the Corporations analysis using the above criteria, the fact that management has asserted that it does not have the intent to sell these securities in an unrealized loss position, and that it is more likely than not the Corporation will not have to sell the securities before recovery of their cost basis, management does not believe that the values of any securities are other-than-temporarily impaired as of December 31, 2010 or 2009.

NOTE 4 Loans and Allowance for Loan Losses

XBRL,body

The Corporation grants commercial, agricultural, consumer and residential loans to customers situated primarily in Isabella, Gratiot, Mecosta, Midland, Western Saginaw, Montcalm and Southern Clare counties in Michigan. The ability of the borrowers to honor their repayment obligations is often dependent upon the real estate, agricultural, light manufacturing, retail, gaming and tourism, higher education, and general economic conditions of this region. Substantially all of the consumer and residential mortgage 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.

A summary of the major classifications of loans is as follows as of December 31:

	2010	2009
Mortgage loans on real estate
Residential 1-4 family	$ 207,749	$ 207,560
Commercial	239,810	224,176
Agricultural	44,246	38,236
Construction and land development	12,250	13,268

Following is a summary of changes in the allowance for loan losses for the years ended December 31:

Balance at beginning of year	2009 — $ 11,982	$	7,301
Allowance of acquired bank			822
Loans charged off	(6,642	)	(6,325	)
Recoveries	1,546		684
Provision charged to income	6,093		9,500
Balance at end of year	$ 12,979	$	11,982

The primary factors behind the determination of the level of the allowance for loan losses (ALLL) are specific allocations for impaired loans, historical loss percentages, as well as current economic conditions. Specific allocations for impaired loans are primarily determined based on the difference between the net realizable value of the loans underlying collateral or the net present value of the projected payment stream and its recorded investment. Historical loss allocations are calculated at the loan class and segment levels based on a migration analysis of the loan portfolio over the preceding three years.

Commercial loans include loans for commercial real estate, farmland and agricultural production, state and political subdivisions, and commercial operating loans. The largest concentration of commercial loans is

XBRL Pagebreak End

commercial real estate. Repayment of commercial loans is often dependent upon the successful operation and management of a business; thus, these loans generally involve greater risk than other types of lending. The Corporation minimizes its risk by limiting the amount of loans to any one borrower to $12,500. Borrowers with credit needs of more than $12,500 are serviced through the use of loan participations with other commercial banks. All commercial real estate loans require loan to value limits of less than 80%. Depending upon the type of loan, past credit history, and current operating results, the Corporation may require the borrower to pledge accounts receivable, inventory, and fixed assets. Personal guarantees are generally required from the owners of closely held corporations, partnerships, and proprietorships. In addition, the Corporation requires annual financial statements, prepares cash flow analyses, and reviews credit reports as deemed necessary.

First and second residential real estate mortgages are the single largest category of loans. The Corporation offers adjustable rate mortgages, fixed rate balloon mortgages, and fixed rate mortgage loans which typically have amortization periods up to a maximum of 30 years. Fixed rate loans with an amortization of greater than 15 years are generally sold upon origination to the Federal Home Loan Mortgage Association. Fixed rate residential mortgage loans with an amortization of 15 years or less may be held in the Corporations portfolio, held for future sale, or sold upon origination. Factors used in determining when to sell these mortgages include managements judgment about the direction of interest rates, the Corporations need for fixed rate assets in the management of its interest rate sensitivity, and overall loan demand.

Construction and land development loans consist primarily of 1 to 4 family residential properties. These loans primarily have a 6 to 9 month maturity and are made using the same underwriting criteria as residential mortgages. Loan proceeds are disbursed in increments as construction progresses and inspections warrant. Construction loans are typically converted to permanent loans at the completion of construction.

Lending policies generally limit the maximum loan to value ratio on residential mortgages to 95% of the lower of the appraised value of the property or the purchase price, with the condition that private mortgage insurance is required on loans with loan to value ratios in excess of 80%. Substantially all loans upon origination have a loan to value ratio of less than 80%. Underwriting criteria for residential real estate loans include: evaluation of the borrowers ability to make monthly payments, the value of the property securing the loan, ensuring the payment of principal, interest, taxes, and hazard insurance does not exceed 28% of a borrowers gross income, all debt servicing does not exceed 36% of income, acceptable credit reports, verification of employment, income, and financial information. Appraisals are performed by independent appraisers. All mortgage loan requests are reviewed by a mortgage loan committee or through a secondary market automated underwriting system; loans in excess of $400 require the approval of the Banks Internal Loan Committee, Board of Directors, or its loan committee.

Consumer loans granted include automobile loans, secured and unsecured personal loans, credit cards, student loans, and overdraft protection related loans. Loans are amortized generally for a period of up to 6 years. The underwriting emphasis is on a borrowers ability to pay rather than collateral value. No consumer loans are sold to the secondary market.

Internally assigned 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 risk ratings for commercial and agricultural loans are as follows:

EXCELLENT Substantially Risk Free

Loans to borrowers with a 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.

HIGH QUALITY Limited Risk

Loans to borrowers with a sound financial condition and 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.

HIGH SATISFACTORY Reasonable Risk

Loans to borrowers with a 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.

LOW SATISFACTORY Acceptable Risk

Loans to borrowers which are considered 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 abilities apparent yet unproven.
	Weakness in primary source of repayment with adequate secondary
source of repayment.
	Loan structure generally in accordance with policy.
	If secured, loan collateral coverage is marginal.
	Adequate cash flow to service debt, but coverage is low.

To be classified as less than satisfactory, only one of the following criteria must be met.

SPECIAL MENTION- Criticized

These borrowers constitute an undue and unwarranted credit risk but not to the point of justifying a classification of substandard. The credit risk may be relatively minor yet constitute an unwarranted risk in light of the circumstances surrounding a specific loan:

	Downward trend in sales, profit levels and margins.
	Impaired working capital position.
	Cash flow is strained in order to meet debt repayment.
	Loan delinquency (30-60 days) and overdrafts may occur.
	Shrinking equity cushion.
	Diminishing primary source of repayment and questionable
secondary source.
	Management abilities are questionable.
	Weak industry conditions.
	Litigation pending against the borrower.
	Loan may need to be restructured to improve collateral position
or reduce payments.
	Collateral / guaranty offers limited protection.
	Negative debt service coverage however well collateralized and
payments current.

SUBSTANDARD Classified

A substandard loan is inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged. There is a distinct possibility that the Corporation will implement collection procedures if the loan deficiencies are not corrected. In addition, the following characteristics may apply:

	Sustained losses have severely eroded the equity and cash flow.
	Deteriorating liquidity.
	Serious management problems or internal fraud.
	Original repayment terms liberalized.
	Likelihood of bankruptcy.
	Inability to access other funding sources.
	Reliance on secondary source of repayment.
	Litigation filed against borrower.
	Collateral provides little or no value.
	Requires excessive attention of the loan officer.
	Borrower is uncooperative with loan officer.

VULNERABLE Classified

This classification includes substandard loans that warrant placing on nonaccrual. 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.

DOUBTFUL Workout

A doubtful loan 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.

LOSS Charge off

Loans classified loss are 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. |

The Corporations primary credit quality indicators for residential real estate and consumer loans is the individual loans past due aging.

NOTE 5 Servicing

XBRL,body

Residential mortgage loans serviced for others are not included in the accompanying consolidated balance sheets. The unpaid principal balance of mortgages serviced for others was $309,882 and $307,656 at December 31, 2010 and 2009, respectively. The fair value of servicing rights was determined using discount rates ranging from 7.50% to 9.00%, prepayment speeds ranging from 6.00% to 48.72%, depending upon the stratification of the specific right and a weighted average default rate of 0.4%. Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts, disbursing payments to investors and taxing authorities, and foreclosure processing.

The following table summarizes the carrying value and changes therein of mortgage servicing rights included in Other Assets as of December 31:

Balance at beginning of year	2010 — $ 2,620		2009 — $ 2,105		2008 — $ 2,198

NOTE 12 Off-Balance-Sheet Activities

XBRL,body

Credit-Related Financial Instruments

The Corporation is 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 its customers. These financial instruments, which include commitments to extend credit and standby letters of credit, involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The contract or notional amounts of these instruments reflect the extent of involvement the Corporation has in a particular class of financial instrument.

	Contract Amount — 2010	2009
Unfunded commitments under lines of credit	$ 110,201	$ 111,711
Commercial and standby letters of credit	4,881	6,509
Commitments to grant loans	13,382	9,645

Unfunded commitments under commercial lines of credit, revolving credit home equity lines of credit and overdraft protection agreements are commitments for possible future extensions of credit to existing customers. The commitments for equity lines of credit may expire without being drawn upon. These lines of credit are uncollateralized and usually do not contain a specified maturity date and may not be drawn upon to the total extent to which the Corporation is committed. A majority of such commitments are at fixed rates of interest; a portion is unsecured.

Commercial and standby letters of credit are conditional commitments issued by the Corporation to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing arrangements, including commercial paper, bond financing, and similar transactions.

These commitments to extend credit and letters of credit mature within one year. The credit risk involved in these transactions is essentially the same as that involved in extending loans to customers. The Corporation evaluates each customers credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Corporation upon the extension of credit, is based on managements credit evaluation of the borrower. While the Corporation considers standby letters of credit to be guarantees, the amount of the liability related to such guarantees on the commitment date is not significant and a liability related to such guarantees is not recorded on the consolidated balance sheets.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The commitments may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if it is deemed necessary by the Corporation, is based on managements credit evaluation of the customer.

The Corporations exposure to credit-related loss in the event of nonperformance by the counter parties to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Corporation uses the same credit policies in deciding to make these commitments as it does for extending loans to customers. No significant losses are anticipated as a result of these commitments.

NOTE 13 On-Balance Sheet Activities

XBRL,body

Derivative Loan Commitments

Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. The Corporation enters into commitments to fund residential mortgage loans at specific times in the future, with the intention that these loans will subsequently be sold in the secondary market. A mortgage loan commitment binds the Corporation to lend funds to a potential borrower at a specified interest rate within a specified period of time, generally up to 60 days after inception of the rate lock.

Outstanding derivative loan commitments expose the Corporation to the risk that the price of the loans arising from the exercise of the loan commitment might decline from the inception of the rate lock to funding of the loan due to increases in mortgage interest rates. If interest rates increase, the value of these loan commitments decreases. Conversely, if interest rates decrease, the value of these loan commitments increases. The notional amount of undesignated interest rate lock commitments was $547 and $760 at December 31, 2010 and 2009, respectively.

Forward Loan Sale Commitments

To protect against the price risk inherent in derivative loan commitments, the Corporation utilizes both mandatory delivery and best efforts forward loan sale commitments to mitigate the risk of potential decreases in the values of loan that would result from the exercise of the derivative loan commitments.

With a mandatory delivery contract, the Corporation commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. If the Corporation fails to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, it is obligated to pay a pair-off fee, based on then current market prices, to the investor to compensate the investor for the shortfall.

With a best efforts contract, the Corporation commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes. Generally, the price the investor will pay the seller for an individual loan is specified prior to the loan being funded (e.g. on the same day the lender commits to lend funds to a potential borrower).

The Corporation expects that these forward loan sale commitments will experience changes in fair value opposite to the change in fair value of derivative loan commitments. The notional amount of undesignated forward loan sale commitments was $1,729 and $3,041 at December 31, 2010 and 2009, respectively.

The fair values of the rate lock loan commitments related to the origination of mortgage loans that will be held for sale and the forward loan sale commitments are deemed insignificant by management and, accordingly, are not recorded in the accompanying consolidated financial statements.

Banking regulations require the Bank to maintain cash reserve balances in currency or as deposits with the Federal Reserve Bank. At December 31, 2010 and 2009, the reserve balances amounted to $470 and $687, respectively.

Banking regulations limit the transfer of assets in the form of dividends, loans, or advances from the Bank to the Corporation. At December 31, 2010, substantially all of the Banks assets were restricted from transfer to the Corporation in the form of loans or advances. Consequently, bank dividends are the principal source of funds for the Corporation. Payment of dividends without regulatory approval is limited to the current years retained net income plus retained net income for the preceding two years, less any required transfers to common stock. At January 1, 2011, the amount available for dividends without regulatory approval was approximately $8,435.

Note 15 Minimum Regulatory Capital Requirements

XBRL,body

The Corporation (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the Federal Reserve Bank and the Federal Deposit Insurance Corporation (The Regulators). Failure to meet minimum capital requirements can initiate mandatory and possibly additional discretionary actions by The Regulators that if undertaken, could have a material effect on the Corporations and Banks financial statements. Under regulatory capital adequacy guidelines and the regulatory framework for prompt corrective action, the Corporation and the Bank must meet specific capital guidelines that include quantitative measures of their assets, liabilities, capital, and certain off-balance-sheet items, as calculated under regulatory accounting standards. The Banks capital amounts and classifications are also subject to qualitative judgments by The Regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

Quantitative measures established by regulation to ensure capital adequacy require the Corporation and the Bank to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined) and Tier 1 capital to average assets (as defined).

Management believes, as of December 31, 2010 and 2009, that the Corporation and the Bank met all capital adequacy requirements to which they are subject.

As of December 31, 2010, the most recent notifications from The Regulators categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following tables. There are no conditions or events since the notifications that management believes has changed the Banks categories. The Corporations and the Banks actual capital amounts (in thousands) and ratios are also presented in the table.

Note 16 Benefit Plans

XBRL,body

401(k) Plan

The Corporation has a 401(k) plan in which substantially all employees are eligible to participate. Employees may contribute up to 50% of their compensation subject to certain limits based on federal tax laws. The Corporation makes a 3.0% safe harbor contribution for all eligible employees and matching contributions equal to 50% of the first 4.0% of an employees compensation contributed to the Plan during the year. Employees are 100% vested in the safe harbor contributions and are 0% vested through their first two years of employment and are 100% vested after

6 years of service for matching contributions. For the year ended December 31, 2010, 2009 and 2008, expenses attributable to the Plan were $625, $617, and $543 respectively.

Defined Benefit Pension Plan

The Corporation has a non-contributory defined benefit pension plan which was curtailed in 2007. Due to the curtailment, future salary increases will not be considered and the benefits are based on years of service and the employees five highest consecutive years of compensation out of the last ten years of service rendered through March 1, 2007.

Changes in the projected benefit obligation and plan assets during each year, the funded status of the plan, and the net amount recognized on the Corporations consolidated balance sheets using an actuarial measurement date of December 31, are summarized as follows during the years ended December 31:

	2010		2009

Net change in unrecognized actuarial loss and prior service cost	(72	)	374
Accrued pension benefit cost at December 31	$ (760	)	$ (542	)

Amounts recognized as a component of other comprehensive loss consist of the following amounts during the years ended December 31 :

Change in unrecognized pension cost	2010 — $ (72	)	2009 — $ 374	$	(2,320	)
Tax effect	25		(127	)	788

losses that arise during the period but are not recognized as components of net periodic benefit cost will be recognized as a component of other comprehensive income (loss). The components of net periodic benefit cost are as follows for the years ended December 31:

	2010
Net periodic benefit cost (income)
Interest cost on projected benefit obligation	$ 531	$	504	$	503
Expected return on plan assets	(491	)	(524	)	(659	)
Amortization of unrecognized actuarial net loss	153		169		4
Net periodic benefit cost (income)	$ 193	$	149	$	(152	)

Accumulated other comprehensive loss at December 31, 2010 includes net unrecognized actuarial losses before income taxes of $3,262, of which $138 is expected to be amortized into benefit cost during 2011.

The actuarial assumptions used in determining the projected benefit obligation and the actual weighted average assumptions used in determining the net periodic pension costs are as follows for the year ended December 31:

Discount rate	6.10 %	5.87 %	6.10 %
Expected long-term rate of return	6.00 %	6.00 %	7.00 %

As a result of the curtailment of the Plan, there is no rate of compensation increase considered in the above assumptions.

The expected long term rate of return is an estimate of anticipated future long term rates of return on plan assets as measured on a market value basis. Factors considered in arriving at this assumption include:

	Historical longer term rates of return for broad asset classes.
	Actual past rates of return achieved by the plan.
	The general mix of assets held by the plan.
	The stated investment policy for the plan.

The selected rate of return is net of anticipated investment related expenses.

Plan Assets

The Corporations overall investment strategy is to moderately grow the portfolio by investing 50% of the portfolio in equity securities and 50% in fixed income securities. This strategy is designed to generate a long term rate of return of 8.7%. Equity securities primarily consist of the S&P 500 Index with a smaller allocation to the Small Cap and International Index. Fixed income securities are invested in the Bond Market Index. The Plan has appropriate assets invested in short term investments to meet near-term benefit payments.

The asset mix and the sector weighting of the investments are determined by the pension committee, which is comprised of members of management of the Corporation. Consultations are held with a third party investment advisor retained by the Corporation to manage the Plan. The Corporation reviews the performance of the advisor no less than annually.

The following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2010 and 2009:

| | Short-term investments: Shares of a money
market portfolio, which is valued using amortized cost, which
approximates fair value. |
| --- | --- |
| | Common collective trusts: These investments
are public investment securities valued using the net asset
value (NAV) provided by a third party investment
advisor. The NAV is quoted on a private market that is not
active; however, the unit price is based on underlying
investments which are traded on an active market. |

The Corporation does not anticipate making any contributions to the plan in 2011.

Estimated future benefit payments are as follows for the next ten years:

Year	Amount
2011	$ 393
2012	406
2013	404
2014	497

Amortization of unrecognized actuarial net loss	153
Net periodic benefit cost	$ 138

Equity Compensation Plan

Pursuant to the terms of the Isabella Bank Corporation and Related Companies Deferred Compensation Plan for Directors (the Directors Plan), directors of the Corporation and its subsidiaries are required to defer at least 25% of their earned board fees into the Directors Plan. The fees are converted on a quarterly basis into the Corporations common stock based on the fair market value of a share of common stock as of the relevant valuation date. Stock credited to a participants account is eligible for stock and cash dividends as declared. Upon retirement from the board or the occurrence of certain other events, the participant is eligible to receive a lump-sum, in-kind, distribution of all of the stock that is then in his or her account, and any unconverted cash will be converted to and rounded up to whole shares of stock and distributed, as well. The Directors Plan does not allow for cash settlement, and therefore, such share based payment awards qualify for classification as equity. All authorized but unissued

shares of common stock are eligible for issuance under the Directors Plan. The Corporation may also purchase shares of common stock on the open market to meet its obligations under the Directors Plan.

In 2008, the Corporation established a Rabbi Trust effective as of July 1, 2008, to fund the Directors Plan. A Rabbi Trust is an irrevocable grantor trust to which the Corporation may contribute assets for the limited purpose of funding a nonqualified deferred compensation plan. Although the Corporation may not reach the assets of the Rabbi Trust (Trust) for any purpose other than meeting its obligations under the Directors Plan, the assets of the Trust remain subject to the claims of the Corporations creditors and are included in the consolidated financial statements. The Corporation may contribute cash or common stock to the Trust from time to time for the sole purpose of funding the Directors Plan. The Trust will use any cash that the Corporation contributed to purchase shares of the Corporations common stock on the open market through the Corporations brokerage services department.

The components of shares eligible to be issued under the Directors Plan were as follows as of December 31:

Eligible		Market	2009 — Eligible	Market
Shares		Value	Shares	Value
Unissued	191,977	$ 3,321	186,279	$ 3,530
Shares held in Rabbi Trust	32,686	565	30,626	580
Total	224,663	$ 3,886	216,905	$ 4,110

Other Employee Benefit Plans

The Corporation maintains a nonqualified supplementary employee retirement plan (SERP) for qualified officers to provide supplemental retirement benefits to each participant. Expenses related to this program for 2010, 2009, and 2008 were $218, $219, and $206, respectively, and are being recognized over the participants expected years of service. As a result of curtailing the Corporations defined benefit plan, the Corporation established an additional SERP to maintain the benefit levels for all employees that were at least forty years old and had at least 15 years of service. The cost to provide this benefit was $145, $124 and $128 for 2010, 2009 and 2008, respectively.

The Corporation maintains a non leveraged employee stock ownership plan (ESOP) and a profit sharing plan which cover substantially all of its employees. Effective December 31, 2006, the ESOP was frozen to new participants. Contributions to the plans are discretionary and are approved by the Board of Directors and recorded as compensation expense. During 2009, the Board of Directors approved a contribution of $50 to the plan. Expenses related to the plans for 2010, 2009, and 2008 were $0, $50, and $0, respectively. Total allocated shares outstanding related to the ESOP at December 31, 2010, 2009, and 2008 were 246,419, 271,421, and 271,520, respectively. Such shares are included in the computation of dividends and earnings per share in each of the respective years.

The Corporation maintains a self funded medical plan under which the Corporation is responsible for the first $50 per year of claims made by a covered family. Medical claims are subject to a lifetime maximum of $5,000 per covered individual. Expenses are accrued based on estimates of the aggregate liability for claims incurred and the Corporations experience. Expenses were $2,101 in 2010, $2,155 in 2009 and $2,110 in 2008.

The Corporation maintains the Isabella Bank Corporation Stockholder Dividend Reinvestment Plan and Employee Stock Purchase Plan (the Dividend Reinvestment Plan). The dividend reinvestment feature of the Dividend Reinvestment Plan allows shareholders to purchase previously unissued Isabella Bank Corporation common shares using dividends paid on shares held in the plan. The employee stock purchase feature of the Dividend Reinvestment Plan allows employees and directors to purchase Isabella Bank Corporation common stock through payroll deduction. The shareholder stock purchase feature of the Dividend Reinvestment Plan enables existing shareholders to purchase additional shares of the Corporations stock directly from the Corporation. The number of shares reserved for issuance under this plan are 885,000, with 313,078 shares unissued at December 31, 2010. During 2010, 2009 and 2008, 124,904 shares were issued for $2,203, 126,874 shares were issued for $2,396 and 78,994 shares were issued for $2,879, respectively, in cash pursuant to these plans.

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, the Corporation uses present value techniques and other valuation methods to estimate the fair values of its 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.

As of December 31, 2010 and 2009, the Corporation had no assets or liabilities measured utilizing Level 1 valuation techniques.

Following is a description of the valuation methodologies and key inputs used to measure financial assets and liabilities recorded at fair value, as well as a description of the methods and significant assumptions used to estimate fair value disclosures for financial instruments not recorded at fair value in their entirety on a recurring basis. For financial assets and liabilities recorded at fair value, the description includes an indication of the level of the fair value hierarchy in which the assets or liabilities are classified.

Cash and demand deposits due from banks:

The carrying amounts of cash and short term investments, including Federal funds sold, approximate fair values.

Certificates of deposit held in other financial institutions:

Interest bearing balances held in unaffiliated financial institutions include certificates of deposit and other short term interest bearing balances that mature within 3 years. Fair value is determined using prices for similar assets with similar characteristics.

Investment securities:

Investment securities are recorded at fair value on a recurring basis. Level 2 fair value measurement is based upon quoted prices, if available. 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 securitys credit rating, prepayment assumptions and other factors such as credit loss and liquidity assumptions. Level 2 securities include bonds issued by government sponsored enterprises, states and political subdivisions, mortgage-backed securities, and collateralized mortgage obligations issued by government sponsored enterprises.

Securities classified as Level 3 include securities in less liquid markets and include auction rate money market preferred securities and preferred stocks. Due to the limited trading activity of these securities, the fair values were estimated utilizing a discounted cash flow analysis as of December 31, 2010 and 2009. These analyses considered creditworthiness of the counterparty, the investment grade, the timing of expected future cash flows, and the current volume of trading activity. The discount rates used were determined by using the interest rates of similarly rated financial institutions debt based on the weighted average of a range of terms for corporate bond interest rates, which were obtained from published sources. All securities have call dates within the next year. The Corporation calculated the present value assuming a 30 year nonamortizing balloon using weighted average discount rates between 3.88% and 6.87% as of December 31, 2010.

Mortgage loans available-for-sale:

Mortgage loans available-for-sale are carried at the lower of cost or market value. The fair value of mortgage loans available-for-sale are based on what price secondary markets are currently offering for portfolios with similar characteristics. As such, the Corporation classifies loans subjected to nonrecurring fair value adjustments as Level 2.

Loans:

For variable rate loans with no significant change in credit risk, fair values are based on carrying values. Fair values for fixed rate loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The resulting amounts are adjusted to estimate the effect of changes in the credit quality of borrowers since the loans were originated.

The Corporation does not record loans at fair value on a recurring basis. However, from time to time, a loan is considered 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, management measures the estimated impairment. The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value, liquidation value, or discounted cash flows. 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.

The Corporation reviews 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, management utilizes independent appraisals, broker price opinions, or internal evaluations. These valuations are reviewed 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 carry and sell an asset if it is determined that the collateral will be liquidated in connection with the ultimate settlement of the loan. The Corporation uses this valuation to determine if any charge offs or specific reserves are necessary. The Corporation 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.

Impaired loans where an allowance is established based on the net realizable value of collateral require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraisal value, the Corporation records the loan as nonrecurring Level 2. When a current appraised value is not available or management determines the fair value collateral is further impaired below the appraised value, the Corporation records the impaired loans as nonrecurring Level 3.

Accrued interest:

The carrying amounts of accrued interest approximate fair value.

Goodwill and other intangible assets:

Acquisition intangibles and goodwill are subject to impairment testing. A projected cash flow valuation method is used in the completion of impairment testing. This valuation method requires a significant degree of management judgment. In the event the projected undiscounted net operating cash flows are less than the carrying value, the asset is recorded at fair value as determined by the valuation model. If the testing resulted in impairment, the Corporation would classify goodwill and other acquisition intangibles subjected to nonrecurring fair value adjustments as Level 3. During 2010 and 2009, there were no impairments recorded on goodwill and other acquisition intangibles.

Equity securities without readily determinable fair values:

The Corporation has investments in equity securities without readily determinable fair values as well as investments in joint ventures. The assets are individually reviewed for impairment on an annual basis by comparing the carrying value to the estimated fair value. The lack of an independent source to validate fair value estimates, including the impact of future capital calls and transfer restrictions, is an inherent limitation in the valuation process. The Corporation classifies nonmarketable equity securities and its investments in joint ventures subjected to nonrecurring fair value adjustments as Level 3. During 2010 and 2009, there were no impairments recorded on equity securities without readily determinable fair values.

Foreclosed assets:

Upon transfer from the loan portfolio, foreclosed assets are adjusted to and subsequently carried at the lower of carrying value or fair value less costs to sell. Net realizable value is based upon independent market prices, appraised values of the collateral, or managements estimation of the value of the collateral and as such, the Corporation classifies foreclosed assets as a nonrecurring Level 2. When management determines that the net realizable value of the collateral is further impaired below the appraised value but there is no observable market price, the Corporation records the foreclosed asset as nonrecurring Level 3.

Originated mortgage servicing rights:

Originated mortgage servicing rights are subject to impairment testing. A valuation model, which utilizes a discounted cash flow analysis using interest rates and prepayment speed assumptions currently quoted for comparable instruments and a discount rate determined by management, is used for impairment testing. If the valuation model reflects a value less than the carrying value, originated mortgage servicing rights are adjusted to fair value through a valuation allowance as determined by the model. As such, the Corporation classifies loan servicing rights subject to nonrecurring fair value adjustments as Level 2.

Deposits:

Demand, savings, and money market deposits are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for variable rate certificates of deposit approximate their recorded carrying value. Fair values for fixed rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Borrowed funds:

The carrying amounts of federal funds purchased, borrowings under overnight repurchase agreements, and other short-term borrowings maturing within ninety days approximate their fair values. The fair values of the Corporations other borrowed funds are estimated using discounted cash flow analyses based on the Corporations current incremental borrowing arrangements.

The Corporation has elected to measure a portion of borrowed funds at fair value. These borrowings are recorded at fair value on a recurring basis, with the fair value measurement estimated using discounted cash flow analysis based on the Corporations current incremental borrowings rates for similar types of borrowing arrangements. Changes in the fair value of these borrowings are included in noninterest income. As such, the Corporation classifies other borrowed funds as Level 2.

Commitments to extend credit, standby letters of credit and undisbursed loans:

Fair values for off balance sheet lending commitments are based on fees currently charged to enter into similar agreements, taking into consideration the remaining terms of the agreements and the counterparties credit standings. The Corporation does not charge fees for lending commitments; thus it is not practicable to estimate the fair value of these instruments.

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. Furthermore, although the Corporation believes its 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.

Managements Discussion and Analysis of Financial Condition and Results of Operations

ISABELLA BANK CORPORATION FINANCIAL REVIEW (All dollars in thousands)

The following is managements discussion and analysis of the financial condition and results of operations for Isabella Bank Corporation. This discussion and analysis is intended to provide a better understanding of the consolidated financial statements and statistical data included elsewhere in the Annual Report.

Executive Summary

Isabella Bank Corporation, as well as all other financial institutions in Michigan and across the entire country, continues to experience the negative impacts on its operations from the recent economic recession and the subsequent recovery. This recession, which began in the fourth quarter of 2008, has resulted in historically high levels of loan delinquencies and nonaccrual loans, which have translated into increases in net loans charged off and foreclosed asset and collection expenses. Additionally, there have been announcements by several large banks stating that they have halted foreclosures due to a failure to properly prepare the documents to complete the foreclosure process. Isabella Bank Corporation has, to its knowledge, materially complied with all laws governing foreclosures.

Despite the recent economic downturn, the Corporation continues to be profitable, with net income of $9,045 for the year ended December 31, 2010. The Corporations nonperforming loans represented 0.83% of total loans as of December 31, 2010 which declined from 1.28% as of December 31, 2009. The ratio of nonperforming loans to total loans for all banks in the Corporations peer group was 3.71% as of September 30, 2010 (December 31, 2010 peer group ratios are not yet available). The Corporations interest margins also continue to be strong, as the net yield on interest earning assets (on a fully tax equivalent basis) was 4.04% for the year ended December 31, 2010.

New Branch Office

As part of the Corporations effort to expand its market area, the Corporation opened a new branch in Midland, Michigan in the third quarter of 2010. The new full service office will expand the Corporations presence in the Midland area as a source for both commercial and consumer loans and deposits.

Recent Legislation

The recently passed Health Care and Education Act of 2010 and the Patient Protection and Affordable Care Act could have a significant impact on the Corporations operating results in future periods. Aside from the potential increases in the Corporations health care costs, the implementation of the new rules and requirements is likely to require a substantial commitment from the Corporations management.

The recently enacted Dodd-Frank Act is very broad and complex legislation that puts in place a sweeping new financial services framework that is likely to have significant regulatory and legal consequences and will likely impact the Corporations future operating results. Implementation of the Act will require compliance with numerous new regulations, which will increase compliance and documentation costs. For more information, see the summary of the Dodd-Frank Act under the heading Regulation in Item 1, included in the Corporations 2010 annual report on Form 10-K.

In September 2010, Congress passed and the President signed into law the Small Business Lending Bill which includes access to capital for community banks. The Corporation continues to be well capitalized and profitable and is not expecting to participate in the program.

Shareholder Stock Purchase Program

The Corporation recently amended its Dividend Reinvestment and Employee Stock Purchase Plan to allow for any current shareholders to purchase additional shares of the Corporations stock directly from the Corporation beginning in the fourth quarter of 2010. For more information regarding that amendment, see the Form S-3D that the Corporation filed with the SEC on October 1, 2010.

Other

The Corporation has not received any notices of regulatory actions as of February 28, 2011.

Critical Accounting Policies:

The Corporations significant accounting policies are set forth in Note 1 of the Consolidated Financial Statements. Of these significant accounting policies, the Corporation considers its policies regarding the allowance for loan losses, acquisition intangibles, and the determination of the fair value of investment securities to be its most critical accounting policies.

The allowance for loan losses requires managements most subjective and complex judgment. Changes in economic conditions can have a significant impact on the allowance for loan losses and, therefore, the provision for loan losses and results of operations. The Corporation has developed appropriate policies and procedures for assessing the adequacy of the allowance for loan losses, recognizing that this process requires a number of assumptions and estimates with respect to its loan portfolio. The Corporations assessments may be impacted in future periods by changes in economic conditions, and the discovery of information with respect to borrowers which is not known to management at the time of the issuance of the consolidated financial statements. For additional discussion concerning the Corporations allowance for loan losses and related matters, see the detailed discussion to follow.

United States generally accepted accounting principles require that the Corporation determine the fair value of the assets and liabilities of an acquired entity, and record their fair value on the date of acquisition. The Corporation employs a variety of measures in the determination of the fair value, including the use of discounted cash flow analysis, market appraisals, and projected future revenue streams. For certain items that management believes it has the appropriate expertise to determine the fair value, management may choose to use its own calculations of the value. In other cases, where the value is not easily determined, the Corporation consults with outside parties to determine the fair value of the identified asset or liability. Once valuations have been adjusted, the net difference between the price paid for the acquired entity and the value of its balance sheet, including identifiable intangibles, is recorded as goodwill. This goodwill is not amortized, but is tested for impairment on at least an annual basis.

The Corporation currently has both available-for-sale and trading investment securities that are carried at fair value. Changes in the fair value of available-for-sale investment securities are included as a component of other comprehensive income, while declines in the fair value of these securities below their cost that are other-than-temporary are reflected as realized losses in the consolidated statements of income. The change in value of trading investment securities is included in current earnings. Management evaluates securities for indications of losses that are considered other-than-temporary, if any, on a regular basis. The market values for available-for-sale and trading investment securities are typically obtained from outside sources and applied to individual securities within the portfolio.

As of December 31, 2010, the Corporation held an auction rate money market preferred security and preferred stock which declined in fair value as a result of the securities interest rates, as they are currently lower than the offering rates of securities with similar characteristics. Despite the limited trading of these securities, management has determined that any declines in the fair value of these securities are the result of changes in interest rates and not risks related to the underlying credit quality of the security. Additionally, none of these securities are deemed to be below investment grade, and management does not intend to sell the securities in an unrealized loss position, and it is more likely than not that the Corporation will not have to sell the securities before recovery of their cost basis. As

a result, the Corporation has not recognized an other-than-temporary impairment related to these declines in fair value.

Net Interest Income

The Corporation derives the majority of its gross income from interest earned on loans and investments, while its most significant expense is the interest cost incurred for funds used. Net interest income is the amount by which interest income on earning assets exceeds the interest cost of deposits and borrowings. Net interest income is influenced by changes in the balance and mix of assets and liabilities and market interest rates. Management exerts some control over these factors; however, Federal Reserve monetary policy and competition have a significant impact. Interest income includes loan fees of $2,196, in 2010, $1,963 in 2009, and $1,808 in 2008. For analytical purposes, net interest income is adjusted to a taxable equivalent basis by adding the income tax savings from interest on tax exempt loans and securities, thus making year to year comparisons more meaningful.

VOLUME AND RATE VARIANCE ANALYSIS

The following table details the dollar amount of changes in FTE net interest income for each major category of interest earning assets and interest bearing liabilities and the amount of change attributable to changes in average balances (volume) or average rates. 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.

Despite a $49,061 increase in interest earning assets in 2010, the $1,842 increase in FTE net interest income was primarily the result of interest rates on interest bearing liabilities decreasing faster than rates earned on interest earning assets. The Corporation anticipates that net interest margin yield will decline slightly during 2011 due to the following factors:

| | While the Corporations liability sensitive balance sheet
has allowed it to benefit from decreases in interest rates, it
also makes the Corporation sensitive to increases in deposit and
borrowing rates. As part of the Corporations goal to
minimize the potential negative impacts of possible increases in
future interest rates, management is actively working to
lengthen the terms of its interest bearing liabilities. This
lengthening has increased the Corporations cost of
funding, reducing net interest income in the short term. |
| --- | --- |
| | Based on the current economic conditions, management does not
anticipate any changes in the target Fed funds rate in the
foreseeable future. As such, the Corporation does not anticipate
significant, if any, changes in market rates. However, there is
the potential for declines in rates earned on interest earning
assets. Most of the potential declines would arise out of the
Corporations investment portfolio, due to securities which
may be called or will mature in 2011, as these funds will likely
be reinvested at significantly lower rates. |

| | Interest rates on residential mortgage loans remain at or near
historical lows. This rate environment has led to strong
consumer demand for fixed rate mortgage products which are
generally sold to the secondary market. As a result, there has
been a significant decline in three and five year balloon
mortgages, which are held on the Corporations balance
sheet. As these balloon mortgages have paid off, the proceeds
from these loans have been reinvested (typically in the form of available-for-sale investment securities) at lower interest rates which has
adversely impacted interest income. |
| --- | --- |
| | Loan growth has been minimal during 2010. As a result, funds
were reinvested from higher yielding loans into lower yielding
investments. |
| | The interest rates on many types of loans including home equity
lines of credit, residential balloon mortgages, variable rate
commercial lines of credit, and investment securities with
acceptable credit and interest rate risks are currently priced
at or below the Corporations current net yield on interest
earning assets. In order to earn additional net interest income,
the Corporation is continuing to extend loans and purchase
investments that will increase net income but decrease net
interest margin yield. |

ALLOWANCE FOR LOAN LOSSES

The viability of any financial institution is ultimately determined by its management of credit risk. Loans outstanding represent the Corporations single largest concentration of risk. The allowance for loan losses (ALLL) is managements estimation of losses in the existing loan portfolio. Factors used to evaluate the loan portfolio, and thus to determine the current charge to expense, include recent loan loss history, financial condition of borrowers, amount of nonperforming and impaired loans, overall economic conditions, and other factors.

The following schedule shows the composition of the provision for loan losses and the allowance for loan losses.

As a result of the recent economic recession, residential real estate values in the Corporations market areas have declined. These declines are the result of increases in the inventory of unsold homes. This increased inventory is partially the result of the inability of potential home buyers to obtain financing due to the tightening of loan underwriting criteria by many financial institutions, brokers and government sponsored agencies and uncertainties associated with industry wide concerns over the foreclosure process. While the Corporation has maintained traditional lending standards, the decline in real estate values has had an adverse impact on customers who are experiencing financial difficulties. Historically, customers who experienced difficulties were able to sell their properties for more than the loan balance owed. The steep decline in real estate values has diminished homeowner equity and led borrowers who are experiencing financial difficulties to default on their mortgage loans.

The Corporation originates and sells fixed rate residential real estate mortgages to the Federal Home Loan Mortgage Corporation (Freddie Mac). The Corporation has not originated loans either for trading or its own portfolio that would be classified as subprime or financed loans for more than 80% of market value unless insured by private third party insurance.

As shown in the preceding table, when comparing 2010 to 2009, net loans charged off increased by $367. This increase is primarily related to one loan, for which a charge off of $1,000 was recorded in the fourth quarter of 2010. Despite the increase in net loans charged off, the overall improvement in the credit quality of the Corporations loan portfolio has allowed the Corporation to reduce its provision for loan losses in 2010 when compared to 2009.

The Corporation allocates the allowance throughout its loan portfolio based on managements assessment of the underlying risks associated with each loan segment. Managements assessments include allocations based on specific impairment allocations, historical loss histories, internally assigned credit ratings, and past due and nonaccrual balances. A portion of the allowance for loan losses is not allocated to any one loan segment, but is instead a reflection of other qualitative risks within the Corporations loan portfolio.

For further discussion on the allocation of the allowance for loan losses, see Note 4 Loans and Allowance for Loan Losses to the Corporations consolidated financial statements.

Loans Past Due and Loans in Nonaccrual Status

Increases in past due and nonaccrual loans can have a significant impact on the ALLL. To determine the potential impact, and corresponding estimated losses, management analyzes its historical loss trends on loans past due 30-89 days, 90 days or more, and nonaccrual loans.

The following tables summarize the Corporations past due and nonaccrual loans as of December 31:

	Total Past Due and Nonaccrual — 2010	2009	2008	2007	2006
Commercial and agricultural	$ 9,606	$ 8,839	$ 13,958	$ 8,746	$ 7,213

The Corporation had no restructured loans in nonaccrual status as of December 31, 2007 or 2006.

The Corporation has taken aggressive actions to avoid foreclosures on borrowers who are willing to work with the Corporation in modifying their loans, thus making them more affordable. These loan restructurings have allowed borrowers to develop a payment structure that will allow them to continue making payments in lieu of foreclosure. Restructured loans that have been placed in nonaccrual status may be placed back on accrual status after six months of continuous performance.

To be classified as a restructured loan, the concessions granted to a customer who is experiencing financial difficulty must meet one of the following criteria:

Reduction of the stated interest rate related to the sole purpose of providing payment and relief for the remaining original life of the debt.
Extension of the amortization period beyond typical lending guidelines.
Forbearance of principal.
Forbearance of accrued interest.

The following table displays the results of the Corporations efforts related to loans restructured since December 31, 2008:

Number of		Amount of	Unsuccessful — Number of	Amount of	Total — Number of	Amount of

Since December 31, 2008, the Corporation has not restructured any loans as a result of a forbearance of principal or accrued interest.

The Corporation has restructured $10,906 of loans since December 31, 2008 and had $5,763 of loans classified as restructured as of December 31, 2010. While the number of loans restructured has increased in 2010, it is a reflection of the Corporations efforts to work with customers to modify the terms of their loan agreements and an indicator that the local economy remains under stress.

Nonperforming Assets

The following table summarizes the Corporations nonperforming assets as of December 31:

	2010	2009	2008	2007	2006
Nonaccrual loans	$ 5,610	$ 8,522	$ 11,175	$ 4,156	$ 3,444

Nonperforming assets as a % of total assets	0.67 %	0.91 %	1.35 %	0.76 %	0.57 %

Loans are placed in nonaccrual status when the foreclosure process has begun, generally after a loan is 90 days past due, unless such loan is well secured and in the process of collection. Upon transferring the loans to nonaccrual status, an evaluation to determine the net realizable value of the underlying collateral is performed. This evaluation is used to help determine if any charge downs are necessary. Loans may be placed back on accrual status after six months of continued performance.

The following table summarizes the Corporations nonaccrual loan balances by type as of December 31:

	2010	2009	2008	2007	2006
Commercial and agricultural	$ 4,140	$ 5,810	$ 8,059	$ 1,959	$ 2,887
Residential mortgage	1,470	2,657	3,092	2,185	557
Consumer installment		55	24	12
	$ 5,610	$ 8,522	$ 11,175	$ 4,156	$ 3,444

Included in nonaccrual commercial and agricultural loans was one credit with a balance of $2,679 as of December 31, 2010. This credit is secured by unsold condominiums and undeveloped commercial real estate for which there has been a specific allocation established in the amount of $345. Commercial and agricultural nonaccrual loans included one credit with a balance of $1,800 as of December 31, 2009 which was subsequently transferred to other real estate owned in the third quarter of 2010. There were no other individually significant credits included in nonaccrual loans as of December 31, 2010, 2009, 2008, 2007, or 2006.

Included in the nonaccrual loan balances above were credits currently classified as restructured loans as of December 31:

	2010	2009	2008
Commercial and agricultural	$ 115	$ 1,692	$ 1,985
Residential mortgage	573	424
	$ 688	$ 2,116	$ 1,985

The Corporation had no restructured loans in nonaccrual status as of December 31, 2007 or 2006.

The Corporation has devoted considerable attention to identifying impaired loans and adjusting the net carrying value of these loans to their current net realizable values through the establishment of a specific reserve or

the recording of a charge off. To managements knowledge, there are no other loans which cause management to have serious doubts as to the ability of a borrower to comply with their loan repayment terms. A continued decline in real estate values may require further write downs of loans in foreclosure and other real estate owned and could potentially have an adverse impact on the Corporations financial performance.

Based on managements analysis, the allowance for loan losses is considered appropriate as of December 31, 2010. Management will continue to closely monitor its overall credit quality during 2011 to ensure that the allowance for loan losses remains appropriate.

Significant changes in noninterest income are detailed below:

Management continuously analyzes various fees related to deposit accounts including: service charges and NSF and overdraft fees. Based on these analyses, the Corporation makes any necessary adjustments to ensure that its fee structure is within the range of its competitors, while at the same time making sure that the fees remain fair to deposit customers. NSF and overdraft fees have been declining over the past two years, and declined further in the third quarter and fourth quarters of 2010 as a result of new regulatory rules issued by the Federal Reserve Bank being implemented related to NSF and overdraft fees. The Corporation anticipates that NSF and overdraft fees will decline further in 2011 as a result of this recent rule making.

| | The increases in ATM and debit card fees are primarily the
result of the increased usage of debit cards by customers. As
management does not anticipate any significant changes to the
ATM and debit card fee structures, these fees are expected to
continue to increase as the usage of debit cards increases. |
| --- | --- |
| | As a result of lower than normal residential mortgage rates, the
Corporation experienced increases in the volume of loans sold to
Freddie Mac beginning in the fourth quarter of 2008. This high
volume led to increases in gains from the sale of mortgage loans
in 2009. The volume of new mortgage activity has returned to
more normal levels in 2010, leading to a decline in the gain on
sale of mortgage loans. Despite the increase in the balance of
serviced loans, the Corporation recorded only modest increases
in the value of its originated mortgage servicing rights
(OMSR) portfolio in 2010 as rates remained at
historically low levels. As interest rates are expected to
increase, the Corporation anticipates that Freddie Mac servicing
fees and net OMSR income will increase in 2011, while the gains
from the sale of mortgage loans will likely decline. |
| | Fluctuations in the gains and losses related to trading
securities and borrowings carried at fair value are caused by
interest rate variances. Management does not anticipate any
significant fluctuations in net trading activities in 2011 as
significant interest rate changes are not expected. |
| | The Corporation does not anticipate any significant sales of available-for-sale investment securities in 2011. |
| | Fees generated from brokerage and advisory services have been
steadily increasing for the past few years. This has been the
result of staff additions as well as a conscious effort by
management to expand the Corporations presence in its
local market. Management anticipates brokerage and advisory fees
to increase further in 2011. |
| | The fluctuation in all other income in 2010 is due partially to
a $133 increase in earnings from the Corporations
investment in Corporate Settlement Solutions. The remainder of
the difference is spread throughout the various categories, none
of which are individually significant. |

Significant changes in noninterest expenses are detailed below:

| | Leased employee salaries have remained essentially unchanged
from 2009. During 2009, the Corporation incurred increased
overtime costs related to the large volume of mortgage
refinancing activity. While the demand for mortgage refinancing
has reduced, the reduction in overtime has been offset by annual
merit increases and the continued growth of the Corporation.
Leased employee benefits fluctuate from period to period
primarily as a result of changes in health care related
expenses. The Corporation does not anticipate any significant
changes in leased employee salaries or benefit expenses in 2011. |
| --- | --- |
| | FDIC insurance premium expense decreased primarily when the year
ended December 31, 2010 is compared to the same period in
2009 as a result of an FDIC special assessment of $479, which
was paid in September 2009. Management expects FDIC insurance
premiums to approximate current levels for 2011. |
| | The increase in marketing and community relations expenses in
2010 is primarily related to the Corporation making a
contribution of $250 to the IBT Foundation, compared to $140 in
2009 and $0 in 2008. |
| | Audit and SOX compliance fees fluctuate due to the timing of the
performance of recurring audit procedures. |
| | Director fees declined in 2010 due to Corporation implementing a
policy whereby the membership on the Isabella Bank and Isabella
Bank Corporations board of directors is identical; no
significant change is expected in 2011. |
| | Printing and supplies expenses were historically high in the
first three months of 2009 as a result of the Corporation
increasing inventories of various supplies. Printing and
supplies expenses are expected to approximate current levels in
2011. |
| | The Corporation places a strong emphasis on customer service. In
February 2010, all of the Corporations employees attended
a special customer service seminar. This seminar coupled with
increases in expenditures for executive leadership training led
to increases in education expenses during 2010. Management
expects that education related expenses may decline slightly in
2011. |
| | Postage and freight expenses have declined, and are expected to
continue to decline, as a result of fewer special mailings as
well as an increase in the Corporations customers usage of
electronic statements. |
| | The Corporations legal expenses can fluctuate from period
to period based on the volume of foreclosures as well as
expenses related to the Corporations ongoing operations,
including regulatory compliance. At this time, the Corporation
is not aware of any significant legal matters, and as such
expects that legal expenses should approximate current levels in
2011. |
| | The fluctuations in all other expenses are spread throughout
various categories, none of which are individually significant. |

Federal Income Taxes

Federal income tax expense (benefit) for 2010 was $1,604 or 15.1% of pre-tax income compared to $846 or 9.8% of income in 2009 and ($724) or (21.4%) in 2008. The primary factor behind the effective rate in 2008 is related to the increase in tax exempt income as a percentage of net income. A reconcilement of actual federal income tax expense reported and the amount computed at the federal statutory rate of 34% is found in Note 11, Federal Income Taxes of Notes to Consolidated Financial Statements.

As shown above, the Corporation has intentionally increased its balance sheet through the acquisition of available-for-sale investment securities and certificates of deposit held in other financial institutions, which is consistent with its plan to increase net interest income. These purchases were funded primarily with retail deposit growth. Available-for-sale investment securities are expected to continue to increase in 2011. Overall changes in deposit accounts and demand for loans are the primary reasons for fluctuations in cash and cash equivalents. As the Corporation has increased its investment securities, it has reduced its interest bearing balances, which is included in cash and cash equivalents.

A discussion of changes in balance sheet amounts by major categories follows:

Trading securities

Trading securities are carried at fair value. The Corporations overall intent is to maintain a trading portfolio to enhance the ongoing restructuring of assets and liabilities as part of our interest rate risk management objectives (See Note 2 Trading Securities of the Consolidated Financial Statements). Due to the current interest rate environment, the Corporation has allowed this balance to decline.

The following is a schedule of the carrying value of trading securities as of December 31:

	2010	2009	2008
Government sponsored enterprises	$	$	$ 4,014
States and political subdivisions	5,837	9,962	11,556

Total	$ 5,837	$ 13,563	$ 21,775

Available-for-sale investment securities

The primary objective of the Corporations investing activities is to provide for safety of the principal invested. Secondary considerations include the need for earnings, liquidity, and the Corporations overall exposure to changes in interest rates. Securities currently classified as available-for-sale are stated at fair value.

The following is a schedule of the carrying value of investment securities available-for-sale as of December 31:

	2010	2009	2008
U.S. Government and federal agencies	$	$	$ 4,083

Excluding those holdings in government sponsored enterprises and municipalities within the state of Michigan, there were no investments in securities of any one issuer that exceeded 10% of shareholders equity. The Corporation has a policy prohibiting investments in securities that it deems are unsuitable due to their inherent credit or market risks. Prohibited investments include stripped mortgage backed securities, zero coupon bonds, nongovernment agency asset backed securities, and structured notes. The Corporations holdings in mortgage-backed securities and collateralized mortgage obligations include only government agencies and government sponsored agencies as the Corporation holds no investments in private label mortgage-backed securities or collateralized mortgage obligations.

The following is a schedule of maturities of available-for-sale investment securities (at carrying value) and their weighted average yield as of December 31, 2010. Weighted average yields have been computed on a fully taxable-equivalent basis using a tax rate of 34%. Mortgage-backed securities and collateralized mortgage obligations are included in maturity categories based on their stated maturity date. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations. Trading securities have been excluded as they are not expected to be held to maturity. Included in the contractual maturity distribution in the following table are auction rate money market preferred securities and preferred stock. Auction rate debt and auction rate preferred securities are long term floating rate instruments for which interest rates are set at periodic auctions. At each successful auction, the Corporation has the option to sell the security at par value. Additionally,

the issuers of auction rate securities generally have the right to redeem or refinance the debt. As a result, the expected life of auction rate securities may differ significantly from the contractual term.

Loans

The largest component of earning assets is loans. The proper management of credit and market risk inherent in the loan portfolio is critical to the financial well being of the Corporation. To control these risks, the Corporation has adopted strict underwriting standards. These standards include specific criteria against lending outside the Corporations defined market areas, lending limits to a single borrower, and strict loan to collateral value limits. The Corporation also monitors and limits loan concentrations extended to distressed industries. The Corporation has no foreign loans and there were no concentrations greater than 10% of total loans that are not disclosed as a separate category in the following table.

The following table presents the composition of the loan portfolio for the years ended December 31:

	2010	2009	2008	2007	2006
Commercial	$ 348,852	$ 340,274	$ 324,806	$ 238,306	$ 212,701

	$ 735,304	$ 723,316	$ 735,385	$ 612,687	$ 591,042

The following table presents the change in the loan categories for the years ended December 31:

	2010 — $ Change	% Change		2009 — $ Change	% Change		2008 — $ Change	% Change
Commercial	$ 8,578		2.5 %	$ 15,468		4.8 %	$ 86,500	36.3 %

Residential real estate mortgage	(1,809	)	−0.6 %	(33,559	)	−10.5 %	21,460	7.2 %
Installment	(1,382	)	−4.3 %	(820	)	−2.5 %	4,142	14.3 %
	$ 11,988		1.7 %	$ (12,069	)	−1.6 %	$ 122,698	20.0 %

The growth in commercial and agricultural loans is a result of the Corporations efforts to increase these segments of the loan portfolio as a percentage of total loans. A significant portion of this growth has been driven by the Corporations new business development team.

As rates in 2010 on residential mortgages were comparable to the rates in 2009, residential mortgage refinancing activity stabilized which resulted in a decrease in loans sold to the secondary market. As a result of this decline in loans sold, the residential real estate portfolio remained stable in 2010 as compared to the significant

declines noted in 2009. Refinancing activity resulted in a net increase of $2,226 in the balance of residential mortgage loans sold to the secondary market in 2010 compared to a net increase of $53,161 in 2009.

A substantial portion of the increase in total loans as of December 31, 2008 compared to December 31, 2007 was a result of the acquisition of Greenville Financial Corporation in January 2008. Pursuant to the acquisition, the Corporation purchased gross loans totaling $88,613.

Equity securities without readily determinable fair values

As shown in the preceding table, the Corporation has enjoyed strong deposit growth during 2010. This growth was the result of the Corporation offering products with competitive rates and terms, as well as focused marketing efforts to increase deposit market share in the communities served. Management anticipates that deposits will continue to grow in 2011.

A substantial portion of the increase in total deposits as of December 31, 2008 compared to December 31, 2007 was a result of the acquisition of Greenville Community Financial Corporation (GCFC) in January 2008. Pursuant to the acquisition, the Corporation purchased deposits totaling $90,151. Exclusive of the GCFC acquisition, deposits decreased $47,994 when December 31, 2008 is compared to December 31, 2007. This decline was the result of increased competition with other depository institutions as well as declines in brokered certificates of deposit and internet certificates of deposit.

The following table shows the average balances and corresponding interest rates paid on deposit accounts as of December 31:

	2010 — Amount	Rate	2009 — Amount	Rate	2008 — Amount	Rate

The Corporation also has loan commitments that may impact liquidity. The following schedule summarizes the Corporations loan commitments and expiration dates by period as of December 31, 2010.

Capital

The capital of the Corporation consists primarily of common stock, including shares to be issued, retained earnings, and accumulated other comprehensive loss. The Corporation offers dividend reinvestment and employee, director, and shareholder stock purchase plans. Under the provisions of these plans, the Corporation issued 122,113 shares of common stock generating $2,164 of capital during 2010, and 126,874 shares of common stock generating $2,396 of capital in 2009. The Corporation also generates capital through the Isabella Bank Corporation and Related Companies Deferred Compensation Plan for Directors (the Directors Plan), its equity compensation plan (See Note 16 Benefit Plans of Notes to Consolidated Financial Statements). Pursuant to this plan, the Corporation generated $650 and $677 of capital in 2010 and 2009, respectively.

The Board of Directors has adopted a common stock repurchase plan. This plan was approved to enable the Corporation to repurchase the Corporations common stock for reissuance to the dividend reinvestment plan, the employee stock purchase plan and for distributions from the Directors Plan. During 2010 and 2009 the Corporation repurchased 138,970 shares of common stock at an average price of $18.40 and 122,612 shares of common stock at an average price of $19.47, respectively.

Accumulated other comprehensive loss decreased $410 in 2010 and consists of $457 of unrealized gains on available-for-sale investment securities which was offset by a $47 increase in unrecognized pension cost. These amounts are net of tax.

The Federal Reserve Boards current recommended minimum primary capital to assets requirement is 6.0%. The Corporations primary capital to average assets ratio, which consists of shareholders equity plus the allowance for loan losses less acquisition intangibles, was 8.24% at year end 2010. There are no commitments for significant capital expenditures.

The Federal Reserve Board has established a minimum risk based capital standard. Under this standard, 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 minimum standard is 8%, of which at least 4% must consist of equity capital net of goodwill. The following table sets forth the percentages required under the Risk Based Capital guidelines and the Corporations values at:

2010	2009	Required
Equity Capital	12.44 %	12.80 %	4.00 %
Secondary Capital	1.25 %	1.25 %	4.00 %
Total Capital	13.69 %	14.05 %	8.00 %

Isabella Bank Corporations secondary capital includes only the allowance for loan losses. The percentage for the secondary capital under the required column is the maximum amount allowed from all sources.

The Federal Reserve Board also prescribes minimum capital requirements for the Corporations subsidiary Bank. At December 31, 2010, the Bank exceeded these minimums. For further information regarding the Banks capital requirements, refer to Note 15 Minimum Regulatory Capital Requirements of the Notes to Consolidated Financial Statements,

Fair Value

The Corporation utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities available-for-sale, trading securities, and certain liabilities are recorded at fair value on a recurring basis. Additionally, from time to time, the Corporation may be required to record at fair value other assets on a nonrecurring basis, such as loans held-for-sale, foreclosed assets, originated mortgage servicing rights, 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.

The table below represents the activity in Level 3 inputs measured on a recurring basis for the year ended December 31:

Level 3 inputs January 1	2010 — $ 10,027	$	5,979
Net unrealized (losses) gains on available-for-sale investment securities	(226	)	4,048
Level 3 inputs December 31	$ 9,801	$	10,027

For further information regarding fair value measurements see Note 1, Nature of Operations and Summary of Significant Accounting Policies and Note 19, Fair Value of the Consolidated Financial Statements.

Interest Rate Sensitivity

Interest rate sensitivity is determined by the amount of earning assets and interest bearing liabilities repricing within a specific time period, and their relative sensitivity to a change in interest rates. Management strives to achieve reasonable stability in the net interest margin through periods of changing interest rates. One tool used by management to measure interest rate sensitivity is gap analysis. As shown in the following table, the gap analysis depicts the Corporations position for specific time periods and the cumulative gap as a percentage of total assets.

Trading securities are included in the 0 to 3 month time frame due to their repricing characteristics. Fixed interest rate investment securities are scheduled according to their contractual maturity. Fixed rate loans are included in the appropriate time frame based on their scheduled amortization. Variable rate loans , which totaled $143,572 as of December 31, 2010, are included in the time frame of their earliest repricing. Time deposit liabilities are scheduled based on their contractual maturity except for variable rate time deposits in the amount of $1,940 that are included in the 0 to 3 month time frame.

Savings, NOW accounts, and money market accounts have no contractual maturity date and are believed to be predominantly noninterest rate sensitive by management. These accounts have been classified in the gap table according to their estimated withdrawal rates based upon managements analysis of deposit runoff over the past five years. Management believes this runoff experience is consistent with its expectation for the future. As of December 31, 2010, the Corporation had a negative cumulative gap within one year. A negative gap position results when more liabilities, within a specified time frame, mature or reprice than assets.

The following table shows the time periods and the amount of assets and liabilities available for interest rate repricing as of December 31, 2010. The interest rate sensitivity information for investment securities is based on the

Liquidity

Liquidity is monitored regularly by the Corporations Market Risk Committee, which consists of members of senior management. The committee reviews projected cash flows, key ratios, and liquidity available from both primary and secondary sources.

The primary sources of the Corporations liquidity are cash and cash equivalents, trading securities, and available-for-sale investment securities, excluding auction rate money market preferred securities and preferred stock due to their illiquidity. These categories totaled $360,677 or 29.4% of assets as of December 31, 2010 as compared to $292,464 or 25.6% in 2009. Liquidity is important for financial institutions because of their need to meet loan funding commitments, depositor withdrawal requests, and various other commitments discussed in the accompanying notes to consolidated financial statements. Liquidity varies significantly daily, based on customer activity.

The primary source of funds for the Corporation is deposits. The Corporation emphasizes interest bearing time deposits as part of its funding strategy. The Corporation also seeks noninterest bearing deposits, or checking accounts, to expand its customer base, while reducing the Corporations cost of funds.

The Corporation has the ability to borrow from the Federal Home Loan Bank, the Federal Reserve Bank, and through various correspondent banks as federal funds. These funding methods typically carry a higher interest rate than traditional market deposit accounts. Some borrowed funds, including Federal Home Loan Bank Advances, Federal Reserve Bank Discount Window Advances, and repurchase agreements, require the Corporation to pledge assets, typically in the form of investment securities or loans, as collateral.

Quantitative and Qualitative Disclosures about Market Risk

The Corporations primary market risks are interest rate risk and liquidity risk. The Corporation has no significant foreign exchange risk, holds limited loans outstanding, and does not utilize interest rate swaps or derivatives, except for interest rate locks and forward loan commitments, in the management of its interest rate risk. Any changes in foreign exchange rates or commodity prices would have an insignificant impact on the Corporations interest income and cash flows. The Corporation does have a significant amount of loans extended to borrowers in agricultural production. The cash flow of such borrowers and ability to service debt is largely dependent on commodity prices. The Corporation mitigates these risks by using conservative price and production yields when calculating a borrowers available cash flow to service their debt.

Interest rate risk (IRR) is the exposure of the Corporations net interest income, its primary source of income, to changes in interest rates. IRR results from the difference in the maturity or repricing frequency of a financial institutions interest earning assets and its interest bearing liabilities. IRR is the fundamental method in which financial institutions earn income and create shareholder value. Excessive exposure to IRR could pose a significant risk to the Corporations earnings and capital.

The Federal Reserve Board, the Corporations primary Federal regulator, has adopted a policy requiring the Board of Directors and senior management to effectively manage the various risks that can have a material impact on the safety and soundness of the Corporation. The risks include credit, interest rate, liquidity, operational, and reputational. The Corporation has policies, procedures and internal controls for measuring and managing these risks. Specifically, the IRR 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 opportunity of assets and liabilities, and the frequency of measuring and reporting to the Board of Directors.

The Corporation uses several techniques to manage IRR. The first method is gap analysis. Gap analysis measures the cash flows and/or the earliest repricing of the Corporations 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 imbedded repricing options contained in assets and liabilities. A substantial portion of the Corporations assets are invested in loans and investment securities with issuer call options. Residential real estate and other consumer loans have imbedded options that allow the borrower to repay

the balance prior to maturity without penalty, while commercial and agricultural loans 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 interest rate for residential mortgages, the level of sales of used homes, and the overall availability of credit in the market place. Generally, a decrease in interest rates will result in an increase in the Corporations cash flows from these assets. A significant portion of the Corporations securities are callable or subject to prepayment. The call option is more likely to be exercised in a period of decreasing interest rates. Investment securities, other than those that are callable, do not have any significant imbedded options. Savings and checking deposits may generally be withdrawn on request without prior notice. The timing of cash flows from these deposits is estimated based on historical experience. Time deposits have penalties that discourage early withdrawals.

The second technique used in the management of IRR is to combine the projected cash flows and repricing characteristics generated by the gap analysis and the interest rates associated with those cash flows to project future interest income. By changing the amount and timing of the cash flows and the repricing interest rates of those cash flows, the Corporation can project the effect of changing interest rates on its interest income. Based on the projections prepared for the year ended December 31, 2010, the Corporations net interest income would decrease during a period of increasing interest rates.

The following tables provide information about the Corporations assets and liabilities that are sensitive to changes in interest rates as of December 31, 2010 and 2009. The Corporation has no interest rate swaps, futures contracts, or other derivative financial options. The principal amounts of assets and time deposits maturing were calculated based on the contractual maturity dates. Savings and NOW accounts are based on managements estimate of their future cash flows.
