PROXY STATEMENT

General Information

As used in this Proxy Statement , references to "the Corporation", “Isabella,” “we,” “our,” “us,” and similar terms refer to the consolidated entity consisting of Isabella Bank Corporation and its subsidiary, Isabella Bank. Isabella Bank Corporation refers solely to the parent holding company, and the “ Bank ” refers to Isabella Bank.

This Proxy Statement is furnished in connection with the solicitation of proxies, to be voted at our Annual Meeting of Shareholders (the “ Annual Meeting ”) which is to be held on Tuesday , May 5, 2015 at 5:00 p.m. at the Comfort Inn Conference Center, 2424 S. Mission Street, Mt. Pleasant, Michigan , or at any adjournment or adjournments thereof, for the purposes set forth in the accompanying Notice of the Annual Meeting of Shareholders and in this Proxy Statement .

This Proxy Statement has been mailed on March 26, 2015 to all holders of record of common stock as of the record date. If a shareholder’s shares are held in the name of a broker, bank, or other nominee, then that party should give the shareholder instructions for voting the shareholder’s shares.

Voting at the Meeting

We have fixed the close of business on March 12, 2015 as the record date for the determination of shareholders entitled to notice of, and to vote at, the Annual Meeting and any adjournment thereof. We have only one class of common stock and no preferred stock. As of March 12, 2015 , there were 7,804,200 shares of stock outstanding. Each outstanding share entitles the holder thereof to one vote on each separate matter presented for vote at the meeting. You may vote on matters that are properly presented at the Annual Meeting by attending the meeting and casting a vote, signing and returning the enclosed proxy, voting on the internet, or voting by phone. You may change your vote or revoke your proxy at any time before it is voted at the Annual Meeting by filing with the Corporation an instrument revoking it, filing a duly executed proxy bearing a later date (including a proxy given over the internet or by phone) or by attending the meeting and electing to vote in person. You are encouraged to vote by mail, internet, or phone.

We will hold the Annual Meeting if a majority of the shares of common stock entitled to vote are represented in person or by proxy. If you sign and return the proxy, those shares will be counted to determine if there is a quorum, even if you abstain or fail to vote on any of the proposals.

Your broker may not vote on the election of directors if you do not furnish instructions for such proposals. You should use the voting instruction card provided by us to instruct the broker to vote the shares, or else your shares will be considered “broker non-votes.” Broker non-votes are shares held by brokers or nominees as to which voting instructions have not been received from the shares’ beneficial owner or the individual entitled to vote those shares and the broker or nominee does not have discretionary voting power under rules applicable to broker-dealers. Under these rules, Proposal 1 is not an item on which brokerage firms may vote in their discretion on your behalf unless you have furnished voting instructions.

At this year’s Annual Meeting , you will elect four directors to serve for a term of three years. You may vote in favor, against, or withhold votes for any or all nominees. Directors are elected by a plurality of the votes cast at the Annual Meeting . Shares not voted, including broker non-votes, have no effect on the elections.

The Audit Committee is responsible for pre-approving all auditing services and permitted non-audit services by our independent auditors, or any other auditing or accounting firm, if those fees are reasonably expected to exceed 5.0% of the current year agreed upon fee for independent audit services. The Audit Committee has established general guidelines for the permissible scope and nature of any permitted non-audit services in connection with its annual review of the audit plan and reviews the guidelines with the Board .

Management has the primary responsibility for the consolidated financial statements and the reporting process including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited consolidated financial statements in the Annual Report with management including a discussion of the 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, management’s assertion on the design and effectiveness of our internal control over financial reporting as of December 31, 2014 .

The Audit Committee reviewed with our independent auditors, who are responsible for expressing an opinion on the conformity of those audited consolidated financial statements with accounting principles generally accepted in the United States of America, their judgments as to the quality, not just the acceptability, of our accounting principles and such other matters as are required to be discussed with the Audit Committee by the standards of the Public Company Accounting Oversight Board (United States), including those described in Auditing Standard No. 16 “Communications with Audit Committees”, as may be modified or supplemented. In addition, the Audit Committee has received the written disclosures and the letter from the independent auditors required by PCAOB Rule 3526, Communication with Audit Committees Concerning Independence, as may be modified or supplemented, and has discussed with the independent auditor the independent auditors’ independence.

The Audit Committee discussed with our internal and independent auditors the overall scope and plans for their respective audits. The Audit Committee meets with the internal and external independent auditors, with and without management present, to discuss the results of their examinations, their evaluations of our internal controls, and the overall quality of our financial reporting process. The Audit Committee held five meetings during 2014 , 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, 2014 for filing with the Securities and Exchange Commission.

Compensation Discussion and Analysis

The Compensation and Human Resource Committee is responsible for reviewing and recommending to the Board the compensation and benefits for the CEO, President and CFO, and executive officers. This Committee evaluates and approves our executive officer and senior management compensation plans, policies, and programs. The CEO recommends to this Committee an appropriate salary for the CFO and named executive officers based on their annual performance reviews and the officer’s years of service along with competitive market data.

Compensation Objectives

The Compensation and Human Resource Committee considers asset growth with the safety and soundness objectives and earnings per share to be the primary ratios in measuring financial performance. Our 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. We believe 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 this Committee are to effectively balance salaries and potential compensation to an officer’s individual management responsibilities and encourage each of them to realize their potential for future contributions. The objectives are designed to attract and retain high performing executive officers who will provide leadership while attaining earnings and performance goals.

What the Compensation Programs are Designed to Reward

Our compensation programs are designed to reward dedicated and conscientious employment, loyalty in terms of continued employment, attainment of job related goals and overall profitability. In measuring an executive officer’s contributions, the Compensation and Human Resource Committee considers numerous factors including, among other things, our growth in terms of asset size and increase in earnings per share. In rewarding loyalty and long-term service, we provide attractive retirement benefits.

Review of Risks Associated with Compensation Plans

Based on an analysis conducted by management and reviewed by the Compensation and Human Resource Committee , we do not believe that compensation programs for employees are reasonably likely to have a material short or long term adverse effect on our operating results.

Use of Consultants

In 2014 and 2012, the Compensation and Human Resource Committee directly engaged the services of Blanchard Consulting Group, an independent compensation consulting firm, to assist with a total compensation review for the CEO, President and CFO, and executive officers of the Corporation. Blanchard Consulting Group does not perform any additional services for us or any members of senior management. In addition, Blanchard Consulting Group does not have any other personal or business relationships with any Board members or officers. During 2013, the Compensation and Human Resource Committee did not employ any services of outside compensation or benefit consultants to assist it in compensation related initiatives.

Elements of Compensation

Our executive compensation program has consisted primarily of base salary and benefits, annual performance incentives, benefits and perquisites, and participation in our retirement plans.

How Elements Fit into Overall Compensation Objectives

Individual elements of our compensation objectives are structured to reward strong financial performance, continued service, and to incentivize our leaders to excel in the future. We continually review our compensation objectives to ensure that they are sufficient to attract and retain exceptional officers.

Why Each of the Elements of Compensation is Chosen and How We Determine Amounts for Each Element

Base Salaries , which include director fees for certain executive officers, are set to provide competitive levels of compensation to attract and retain officers with strong leadership skills. Each officer’s performance, current compensation, and responsibilities are considered by the Compensation and Human Resource Committee when establishing base salaries. We also believe it is best to pay sufficient base salary because we believe an over-reliance on equity incentive compensation could potentially skew incentives toward short-term maximization of shareholder value as opposed to building long-term shareholder

Table of Contents

value. Competitive base salary encourages management to operate in a safe and sound manner even when incentive goals may prove unattainable.

The Compensation and Human Resource Committee ’s approach to determining the annual base salary of executive officers is to offer competitive salaries in comparison with other comparable financial institutions. In 2014 and 2012, this Committee utilized both an independent compensation consultant, Blanchard Consulting Group, and a survey prepared by the Michigan Bankers Association of similar sized Michigan based financial institutions. The independent compensation consultant established a benchmark peer group of 23 midwest financial institutions in non-urban areas with comparable average assets size ($1 billion—$2.4 billion), number of branch locations, return on average assets, and nonperforming assets. The Michigan Bankers Association 2014 compensation survey was based on the compensation information provided by these organizations for 2013. Specific factors used to decide where an executive officer’s salary should be within the established range include the historical financial performance, financial performance outlook, years of service, and job performance. The Compensation and Human Resource Committee targeted total compensation for the CEO, the President & CFO, and Bank President using ranges obtained from the Michigan Bankers Association compensation survey as well as any ranges obtained from the independent compensation consultant. Compensation for other named executive officers was based on the ranges provided by the Michigan Bankers Association survey. The Michigan Bankers Association survey was utilized in 2013 as well.

Annual Performance Incentives are used to reward executive officers based on our overall financial performance. This element of the compensation program is included in the overall compensation in order to reward employees above and beyond their base salaries when our performance and profitability exceed established annual targets. The inclusion of this modest incentive encourages management to be creative and diligent in managing to achieve specific financial goals without incurring inordinate risks. Annual performance incentives paid in 2014 were determined by reference to six performance measures that related to services performed in 2013 . The maximum award that may be granted to each eligible employee equals 10% of the employee’s base salary (the “ Maximum Award ”).

The payment of 35% of the Maximum Award (“personal performance goals”) is based on the achievement of goals set for each individual. An analysis is conducted by the CEO. The CEO makes a recommendation to the Compensation and Human Resource Committee for the appropriate amount for each individual executive officer. This Committee reviews, modifies if necessary, and approves the recommendations of the CEO. This Committee also reviews the performance of the CEO. The Compensation and Human Resource 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; and

• Other strategic goals as established by the Board .

Each of the executive officers who were eligible to participate in 2013 accomplished their personal performance goals and were accordingly paid 35% of the 2013 Maximum Award in 2014 .

The payment of the remaining 65% of the Maximum Award (“corporate performance goals”) was conditioned on the achievement of targets in the following six categories:

• Earnings per share (weighted 40% );

• Net operating expenses to average assets (weighted 20% );

• Fully Taxable Equivalent (“FTE”) net interest margin, excluding loan fees (weighted 10% );

• Loan growth (weighted 10% );

• In-market deposit growth (weighted 10% ); and

• Exceeding peer group return on average assets (weighted 10% ).

Benefits and Perquisites. Executive officers are eligible for all of the benefits made available to full-time employees (such as 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.

We also provide our executive officers with certain additional perquisites, which we believe are appropriate in order to attract and retain the proper quality of talent for these positions and to recognize that similar executive perquisites are commonly offered by comparable financial institutions. We maintain 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 Bank as the sole owner and beneficiary of the policies. We believe that perquisites provided to our executive officers in 2014 represented a reasonable percentage of each executive’s total compensation package and are consistent, in the aggregate, with perquisites provided to executive officers of comparable financial institutions. A description and the cost of these perquisites are included in footnote 1 in the “ Summary Compensation Table ” appearing on page 12, the table outlining the change in pension value on page 13, and the “ Nonqualified Deferred Compensation Table ” appearing on page 14.

Retirement Plans . Our retirement plans are designed to assist executives in providing themselves with a financially secure retirement. The retirement plans include a 401(k) plan, a frozen defined benefit pension plan, a frozen non-leveraged employee stock ownership plan (“ ESOP ”), and a retirement bonus plan.

We have a 401(k) plan, in which substantially all employees are eligible to participate. Employees may contribute up to 100% of their compensation subject to certain limits based on federal tax laws. The plan was amended in 2013 to provide a matching safe harbor contribution for all eligible employees equal to 100% of the first 5.0% of an employee's compensation contributed to the Plan during the year. Employees are 100% vested in the safe harbor matching contributions.

For 2012, we made a 3.0% safe harbor contribution for all eligible employees and matching contributions equal to 50% of the first 4.0% of an employee’s compensation contributed to the Plan during the year. Employees were 100% vested in the safe harbor contributions and were 0% vested through their first two years of employment and were 100% vested after 6 years of service for matching contributions.

Our defined benefit pension plan was curtailed effective March 1, 2007 and the current participants’ accrued benefits were frozen as of that date. Participation in the plan was limited to eligible employees as of December 31, 2006.

Our non-leveraged ESOP was frozen effective December 31, 2006 to new participants. Contributions to the plan are discretionary and approved by the Board .

The retirement bonus plan is a nonqualified plan of deferred compensation benefits for eligible employees effective January 1, 2007. Benefit amounts are determined pursuant to the payment schedule adopted at the sole and exclusive discretion of the Board .

Defined benefit pension plan . We sponsor the Isabella Bank Corporation Pension Plan, a frozen defined benefit pension plan. The curtailment, which was effective March 1, 2007, froze the current participant’s accrued benefits as of that date and limited participation in the plan to eligible employees as of December 31, 2006. Due to the curtailment of the plan, the number of years of credited service was frozen. As such, the years of credited service for the plan may differ from the participant’s actual years of service.

Annual contributions are made to the plan as required by accepted actuarial principles, applicable federal tax laws, and to pay expenses related to operating and maintaining the plan. The amount of contributions on behalf of any one participant cannot be separately or individually computed.

Pension plan benefits are based on years of service and the employees’ five highest consecutive years of compensation out of the last ten years of service, through December 31, 2006.

A participant may earn a benefit for up to 35 years of accredited service. Earned benefits are 100% vested after five years of service. Benefit payments normally start when a participant reaches age 65. A participant with more than five years of service may elect to take early retirement benefits anytime after reaching age 55. Benefits payable under early retirement are reduced actuarially for each month prior to age 65 in which benefits begin.

Dennis P. Angner and Steven D. Pung are eligible for early retirement under the 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 . We sponsor the Isabella Bank Corporation Retirement Bonus Plan. This nonqualified plan is intended to provide eligible employees with additional retirement benefits. To be eligible, the employee needed to be an employee on January 1, 2007, and be a participant in our frozen Executive Supplemental Income Agreement. Participants must also be an officer with at least 10 years of service as of December 31, 2006. We have sole and exclusive discretion to add new participants to the plan by authorizing such participation pursuant to action of the Board .

An initial amount was credited for each eligible employee as of January 1, 2007. Subsequent amounts have been credited on each allocation date thereafter as defined in the plan. The amount of the initial allocation and the annual allocation shall be determined pursuant to the payment schedule adopted at our sole and exclusive discretion, as set forth in the plan.

Dennis P. Angner and Steven D. Pung are eligible for early retirement under the 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.

Under the Deferred Compensation Plan for Directors (" Directors Plan "), named executive officers who serve as directors, are required to invest at least 25% of their board fees in our common stock and may invest up to 100% of their earned fees based on their annual election. These amounts are reflected in the above table. These stock investments can be made either through deferred fees or through the purchase of shares through the Isabella Bank Corporation Stockholder Dividend Reinvestment and Employee Stock Purchase Plan (" DRIP Plan "). Deferred fees, under the Directors Plan, are converted on a quarterly basis into shares of our common stock based on the fair market value of shares at that time. Shares credited to a participant’s account are eligible for stock and cash dividends as paid. DRIP Plan shares are purchased on a monthly basis pursuant to the DRIP Plan .

Distribution of deferred fees 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 our common stock. Any common stock issued under deferred fees from the Directors Plan will be considered restricted stock under the Securities Act of 1933, as amended. Common stock purchased through the DRIP Plan are not considered restricted stock under the Securities Act of 1933, as amended.

Potential Payments Upon Termination or Change in Control

The estimated amounts payable to each named executive officer upon severance from employment, retirement, termination upon death or disability or termination following a change in control are described below. For all termination scenarios, the amounts assume such termination took place as of December 31, 2014 .

Any Severance of Employment

Regardless of the manner in which a named executive officer’s employment terminates, he or she is entitled to receive amounts earned during his or her term of employment. Such amounts include:

• Amounts accrued and vested through the Defined Benefit Pension Plan.

• Amounts accrued and vested through the Retirement Bonus Plan.

• Amounts 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.

Table of Contents

Death or Disability

In the event of death or disability of an executive officer, in addition to the benefits listed above, the executive officer will also receive payments under our life insurance plan or under our disability plan as appropriate.

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:

Name	While an Active Employee	Subsequent to Retirement
Jae A. Evans	$ 530,000	$ 265,000
Dennis P. Angner	616,000	308,000

Jerome E. Schwind	422,000	211,000
David J. Reetz	298,000	149,000

Change in Control

We currently do 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.

(1) Directors electing to receive all fees in cash, resulting in no contributions to the Directors Plan , invest at least 25% of their board fees in our common stock under the DRIP Plan as described in our Directors Plan on page 14.

We paid $ 1,350 per board meeting plus a retainer of $ 7,500 to each member during 2014 . Members of the Audit Committee were paid $ 600 per Audit Committee meeting attended. Members of the Nominating and Corporate Governance Committee were paid $ 300 per meeting attended.

Under the Directors Plan , upon a participant’s attainment of age 70, retirement from the Board , or the occurrence of certain other events, they are eligible to receive a lump-sum, in-kind distribution of all of the stock that is then credited to their account. The plan does not allow for cash settlement. Stock issued under the Directors Plan is restricted stock under the Securities Act of 1933, as amended.

We established a Rabbi Trust to fund the Directors Plan . The Rabbi Trust is an irrevocable grantor trust to which we may contribute assets for the limited purpose of funding a nonqualified deferred compensation plan. Although we may not reach the assets of the Rabbi Trust for any purpose other than meeting its obligations under the Directors Plan , the assets of the Rabbi Trust remain subject to the claims of our creditors. We may contribute cash or common stock to the Rabbi Trust from time-to-

time for the sole purpose of funding the Directors Plan . The Rabbi Trust will use any cash that we may contribute to purchase shares of our common stock on the open market.

We transferred $ 338,649 to the Rabbi Trust in 2014 , which held 13,934 shares of our common stock for settlement as of December 31, 2014 . As of December 31, 2014 , there were 173,435 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 Rabbi Trust . All amounts are unsecured claims against our general assets. The net cost of this benefit was $ 154,107 in 2014 .

The following table displays the cumulative number of equity shares credited to the accounts of current directors pursuant to the terms of the Directors Plan as of March 12, 2015 :

Compensation and Human Resource Committee Interlocks and Insider Participation

In 2014 , the Compensation and Human Resource Committee members were directors Barnes, Hubscher, Kleinhardt, LaFramboise, Maness, Manifold, McGuire and Opperman. No executive officer of the Corporation serves on any board of directors or compensation committee of any entity that compensates any member of the Compensation and Human Resource Committee .

Indebtedness of and Transactions with Management

Certain directors and officers and members of their families were loan customers of the Bank , or have been directors or officers of corporations, members or managers of limited liability companies, or partners of partnerships which have had transactions with the Bank . In our opinion, all such transactions were made in the ordinary course of business and were substantially on the same terms, including collateral and interest rates, as those prevailing at the same time for comparable transactions with customers not related to the Bank . These transactions do not involve more than normal risk of collectability or present other unfavorable features. Total loans to these customers were approximately $3,822,000 as of December 31, 2014 . We address transactions with related parties in our Code of Business Conduct and Ethics Policy . Conflicts of interest are prohibited, except under board approved guidelines.

Independent Registered Public Accounting Firm

The Audit Committee has appointed Rehmann Robson LLC as our independent auditors for the year ending December 31, 2015 .

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

Fees for Professional Services Provided by Rehmann Robson LLC

The following table shows the aggregate fees billed by Rehmann Robson LLC for the audit and other services provided for:

	2014	2013
Audit fees	$ 278,178	$ 271,380
Audit related fees	18,760	29,425
Tax fees	24,210	27,095
Total	$ 321,148	$ 327,900

The audit fees were for performing the integrated audit of our consolidated annual financial statements and the internal control attestation report related to the Federal Deposit Insurance Corporation Improvement Act, review of interim quarterly financial statements included in our Forms 10-Q, and services that are normally provided by Rehmann Robson LLC in connection with statutory and regulatory filings or engagements.

Table of Contents

The audit related fees are typically for various discussions related to the adoption and interpretation of new accounting pronouncements. During 2014 , this includes fees for procedures related to nonrecurring regulatory filings. Also included are fees for auditing of our employee benefit plans.

The tax fees were for the preparation of our state and federal tax returns and for consultation on various tax matters.

The Audit Committee has considered whether the services provided by Rehmann Robson LLC , other than the audit fees, are compatible with maintaining Rehmann Robson LLC ’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 LLC 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 SEC rules, the Audit Committee has authorized its chairperson to pre-approve audit, audit-related, tax and non-audit services, provided that such approved service is reported to the full Audit Committee at its next meeting.

As early as practicable in each calendar year, the independent auditor provides to the Audit Committee a schedule of the audit and other services that the independent auditor expects to provide or may provide during the next twelve months. The schedule will be specific as to the nature of the proposed services, the proposed fees, timing, and other details that the Audit Committee may request. The Audit Committee will by resolution authorize or decline the proposed services. Upon approval, this schedule will serve as the budget for fees by specific activity or service for the next twelve months.

A schedule of additional services proposed to be provided by the independent auditor, or proposed revisions to services already approved, along with associated proposed fees, may be presented to the Audit Committee for their consideration and approval at any time. The schedule will be specific as to the nature of the proposed service, the proposed fee, and other details that the Audit Committee may request. The Audit Committee will by resolution authorize or decline authorization for each proposed new service.

Applicable SEC rules and regulations permit waiver of the pre-approval requirements for services other than audit, review or attest services if certain conditions are met. Out of the services characterized above as audit-related, tax and professional services, none were billed pursuant to these provisions in 2014 and 2013 without pre-approval.

Shareholder Proposals

Any proposals which you intend to present at the next Annual Meeting must be received before November 27, 2015 to be considered for inclusion in our 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

Our directors are encouraged to attend the Annual Meeting . At the 2014 Annual Meeting , all directors were in attendance, with the exception of Dr. Barnes.

Section 16(a) Beneficial Ownership Reporting Compliance

These officers, directors, and greater than 10% shareholders are required by SEC regulation to furnish us with copies of these reports.

To our knowledge, based solely on review of the copies of such reports furnished, during the year ended December 31, 2014 all Section 16(a) filing requirements were satisfied, with respect to the applicable officers, directors, and greater than 10% beneficial owners with the exception of the following: Director Barz filed one late report for two reportable transactions, Director Hubscher filed two late reports for one reportable transaction, and Director Opperman filed one late report for two reportable transactions.

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

Management's Discussion and Analysis of Financial Condition and Results of Operations

ISABELLA BANK CORPORATION FINANCIAL REVIEW

( Dollars in thousands except per share amounts )

The following is management’s discussion and analysis of the financial condition and results of our operations. This discussion and analysis is intended to provide a better understanding of the consolidated financial statements and statistical data included elsewhere in this Annual Report on Form 10-K .

Executive Summary

We reported record net income of $13,724 and earnings per common share of $1.77 for the year ended December 31, 2014 . Our continued strong earnings have primarily been the result of a continued improvement in credit quality indicators. These improvements resulted in a decline in the level of the ALLL in both amount and as a percentage of gross loans, resulting in a reversal of provision for loan losses of $668 for the year ended December 31, 2014 . Net loan charge-offs during 2014 were $732 as compared to $1,547 in 2013 which is a 52.68% decline. Additionally, we continue to see reductions in loans classified as less than satisfactory.

During the year, total assets grew by 3.78% to $1,549,543 , and assets under management increased to $2,222,060 which includes loans sold and serviced, and assets managed by our Investment and Trust Services Department of $672,517 . We enjoyed total loan growth of $25,545 which was driven by commercial and agricultural loan growth of $51,989 . This was partially offset by declines in both residential real estate and consumer loans of $26,444 as demand for residential real estate loans continued to be soft and the market for consumer loans continued to be dominated by automobile manufacturers.

While our net yield on interest earning assets of 3.45% remains historically low, it has stabilized. The low net yield on interest earning assets is a direct result of Federal Reserve Bank monetary policy. While we expect the Federal Reserve Bank to increase short term interest rates in 2015, we do not anticipate any significant improvements in our net yield on interest earning assets as the rates paid on interest bearing liabilities will likely increase faster than those of interest earning assets. Net interest income will increase only through continued growth in loans, investments, and other income earning assets.

We anticipate that competition for commercial loans will continue to be significant, residential mortgage loan activity will remain soft, and growing our deposit base will be challenging throughout the foreseeable future. Despite these challenges, our unwavering commitment to core community banking principles and long term sustainable growth has, and will continue to, enable us to meet the needs of the communities we serve and increase shareholder value.

Recent Legislation

The Health Care and Education Act of 2010, the Patient Protection and Affordable Care Act, the Dodd-Frank Act , and the JOBS Act , have already had, and are expected to continue to have, a negative impact on our operating results. Of these four acts, the Dodd-Frank Act has had the most significant impact. The Dodd-Frank Act established the CFPB which has made significant changes in the regulation of financial institutions aimed at strengthening the oversight of the federal government over the operation of the financial services sector and increasing the protection of consumers. Rules issued by the CFPB regarding consumer lending, including residential mortgage lending have increased our compensation and outside advisor costs to ensure our compliance with the new regulations and this trend is expected to continue.

On July 2, 2013, the FRB published revised BASEL III Capital standards for banks. The rules redefine what is included or deducted from equity capital, changes risk weighting for certain on and off-balance sheet assets, increases the minimum required equity capital to be considered well capitalized, and introduces a capital cushion buffer. The rules, which will be gradually phased in between 2015 and 2019, are not expected to have a material impact on the Corporation but will require us to hold more capital than we have historically.

Other

We have not received any notices of regulatory actions as of February 27, 2015 .

CRITICAL ACCOUNTING POLICIES

Our significant accounting policies are set forth in “ Note 1 – Nature of Operations and Summary of Significant Accounting Policies ” of the “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data . Of these significant accounting policies, we consider our policies regarding the ALLL , acquisition intangibles and goodwill, and the determination of the fair value and assessment of OTTI of investment securities to be our most critical accounting policies.

The ALLL requires our most subjective and complex judgment. Changes in economic conditions can have a significant impact on the ALLL and, therefore, the provision for loan losses and results of operations. We have developed policies and procedures for assessing the appropriateness of the ALLL , recognizing that this process requires a number of assumptions and estimates with respect to our loan portfolio. Our 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 us at the time of the issuance of the consolidated financial statements . For additional discussion concerning our ALLL and related matters, see the detailed discussion to follow under the caption “ Allowance for Loan and Lease Losses ” and “ Note 5 – Loans and ALLL ” of the “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data .

U.S. generally accepted accounting principles require that we determine the fair value of the assets and liabilities of an acquired entity, and record their fair value on the date of acquisition. We employ 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 we believe we have the appropriate expertise to determine the fair value, we may choose to use our own calculations of the value. In other cases, where the value is not easily determined, we consult 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 net value of assets acquired on our balance sheet, including identifiable intangibles, is recorded as goodwill. Acquisition intangibles and goodwill are qualitatively evaluated to determine if it is more likely than not that the carrying balance is impaired on at least an annual basis.

AFS securities are carried at fair value with changes in the fair value included as a component of other comprehensive income. Declines in the fair value of AFS securities below their cost that are other-than-temporary are reflected as realized losses in the consolidated statements of income. We evaluate AFS securities for indications of losses that are considered other-than-temporary , if any, on a regular basis. The market values for AFS investment securities are typically obtained from outside sources and applied to individual securities within the portfolio.

Net Interest Income

Net interest income is the amount by which interest income on earning assets exceeds the interest expenses on interest bearing liabilities. Net interest income is influenced by changes in the balance and mix of assets and liabilities and market interest rates. We exert some control over these factors; however, FRB monetary policy and competition have a significant impact. For analytical purposes, net interest income is adjusted to an FTE basis by adding the income tax savings from interest on tax exempt loans, and nontaxable investment securities, thus making year to year comparisons more meaningful. Included in interest income are loan fees which are displayed in the following table for the years ended December 31 :

	2014	2013	2012
Loan fees	$ 2,199	$ 3,182	$ 3,178

Volume and Rate Variance Analysis

The following table sets forth the effect of volume and rate changes on interest income and expense for the periods indicated. For the purpose of this table, changes in interest due to volume and rate were determined as follows:

Volume—change in volume multiplied by the previous period's FTE rate.

Rate—change in the FTE rate multiplied by the previous period's volume.

The change in interest due to both volume and rate has been allocated to volume and rate changes in proportion to the relationship of the absolute dollar amounts of the change in each.

Our net yield on interest earning assets remains at historically low levels which is a direct result of FRB monetary policy. The persistent low interest rate environment coupled with an increase in the concentration of AFS securities as a percentage of earning assets has also placed downward pressure on net interest margin yield. While we anticipate that the FRB will increase short term interest rates in 2015, we do not expect any significant change in our net yield on interest earning assets as the rates paid on interest bearing liabilities will likely increase faster than those of interest earning assets. Net interest income will increase only through continued balance sheet growth.

One of the the primary contributors to the decline in the net yield on interest earning assets during 2014 was a drastic decline in loan fees. Loan fees have declined as the demand for residential mortgage loans has diminished and the competition for commercial loans remains intense. As shown in the following table, the net yield on interest earning assets and net interest income excluding the impact of loan fees (FTE) has remained essentially unchanged since the fourth quarter of 2013. The following table displays unaudited data for the three month periods ended:

Allowance for Loan and Lease Losses

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

The following table summarizes our charge-offs , recoveries, provisions for loan losses, and ALLL balances as of, and for the unaudited three month periods ended:

Total charge-offs	December 31 2014 — $ 351		September 30 2014 — $ 416		June 30 2014 — $ 411		March 31 2014 — $ 450		December 31 2013 — $ 497

As the level of net loan charge-offs continues to decline and credit quality indicators continue to improve, we have reduced the ALLL in both amount and as a percentage of loans. For further discussion of the allocation of the ALLL , see “ Note 5 – Loans and ALLL ” of the “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data .

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, we analyze our historical loss trends on loans past due greater than 30 days and nonaccrual loans. We monitor all loans that are past due and in nonaccrual status for indications of additional deterioration.

	Total Past Due and Nonaccrual — December 31 2014	September 30 2014	June 30 2014	March 31 2014	December 31 2013

Troubled Debt Restructurings

We have taken a proactive approach to avoid foreclosures on borrowers who are willing to work with us in modifying their loans, thus making them more affordable. While this approach has allowed certain borrowers to develop a payment structure

Table of Contents

that will allow them to continue making payments in lieu of foreclosure, it has contributed to a significant increase in the level of loans classified as TDRs . The modifications have been successful for us and our customers as very few of the modified loans have resulted in foreclosures. At the time of the TDR , the loan is reviewed to determine whether or not to classify the loan as accrual or nonaccrual . The majority of new modifications result in terms that satisfy our criteria for continued interest accrual. TDRs that have been placed in nonaccrual status may be placed back on accrual status after six months of continued performance.

We restructure debt with borrowers who due to temporary financial difficulties are unable to service their debt under the original terms. We may extend the amortization period, reduce interest rates, forgive principal, forgive interest, or a combination of these modifications. Typically, the modifications are for a period of five years or less. There were no TDRs that were Government sponsored as of December 31, 2014 or December 31, 2013 .

Losses associated with TDRs , if any, are included in the estimation of the ALLL in the quarter in which a loan is identified as a TDR , and we review the analysis of the ALLL estimation each reporting period to ensure its continued appropriateness.

The following tables provide a roll-forward of TDRs for the years ended December 31, 2013 and 2014 :

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

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

Additional disclosures about nonaccrual loans are included in “ Note 5 – Loans and ALLL ”of the “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data .

We continue to devote 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 . We believe that all loans deemed to be impaired have been identified.

We believe that the level of the ALLL is appropriate as of December 31, 2014 and we will continue to closely monitor overall credit quality and our policies and procedures related to the analysis of the ALLL to ensure that the ALLL remains appropriate.

Significant changes in noninterest income are detailed below:

• As customers continue to increase their dependence on ATM and debit cards, we have realized a corresponding increase in fees. We do not anticipate significant changes to our ATM and debit fee structure; however, we do expect that these fees will continue to increase as the usage of ATM and debit cards increase.

• Offering rates on residential mortgage loans, as well as the decline in loan demand, are the most significant drivers behind fluctuations in the gain on sale of mortgage loans and net OMSR income (loss). As a result of the lack of demand in residential mortgage loan originations, we are experiencing declines in both the gain on sale of mortgage loans and net OMSR income (loss). As mortgage rates are expected to approximate current levels in the foreseeable future and purchase money mortgage activity will likely remain soft, we do not anticipate any significant changes in origination volumes or the gain on sale of mortgage loans.

• We are continually analyzing our AFS securities for potential sale opportunities. These analyses identified several mortgage-backed securities pools in 2014, 2013, and 2012 that made economic sense to sell.

• In recent periods, we have invested considerable efforts to increase our market share in trust and brokerage advisory services. These efforts have translated into increases in trust fees and brokerage and advisory fees.

• The fluctuations in all other income is spread throughout various categories, none of which are individually significant.

Significant changes in noninterest expenses are detailed below:

• Employee salaries have increased as a result of normal merit increases and additional staffing required by our continued growth. The decline in employee benefits is related to health care costs as a result of lower than anticipated claims. Employee benefits are expected to increase moderately in future periods as a result of anticipated increases in health care costs.

• We have consistently been a strong supporter of the various communities, schools, and charities in the markets we serve. We sponsor a foundation, which we established in 1996, that is funded by discretionary donations. The affiliated foundation provides centralized oversight for donations to organizations that benefit our communities. Included in marketing and community relations were discretionary donations to the foundation of $500 , $200 , and $850 for the years ended December 31, 2014, 2013, and 2012, respectively.

• FDIC insurance premiums were elevated in 2013 due to us receiving less of a refund for prepaid FDIC insurance premiums than we had anticipated. FDIC insurance premiums have returned to normalized levels and are anticipated to approximate current levels in 2015.

• We place a strong emphasis on employee development through continuous education. Education and travel expenses vary from year to year based on the timing of various programs that our employees attend.

• Loan underwriting fees have declined in 2014 as a result of declines in residential real estate loan originations.

• Other losses increased significantly in 2014 primarily as a result of losses incurred related to fraudulent activities. Also contributing to losses in both 2014 and 2012 were losses related to the repurchase of loans that we previously sold to a third party. While other losses fluctuate from period to period, they are expected to approximate 2013 levels in 2015.

• The fluctuations in all other expenses are spread throughout various categories, none of which are individually significant.

TOTAL LIABILITIES AND SHAREHOLDERS’ EQUITY	$ 1,549,543	$ 1,493,137		$ 56,406		3.78	%

As shown above, total assets have increased $56,406 since December 31, 2013 . During 2014 , we increased our cost basis of AFS securities by $44,279 while loans grew by $25,545 . Contributing to the increase in our AFS securities portfolio were $11,193 in unrealized gains observed during the year. This balance sheet growth was funded by increases in both deposits and borrowed funds. While we do anticipate that generating quality loans will continue to be competitive, we expect that loans will continue to grow in 2015 .

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

Cash and cash equivalents

Included in cash and cash equivalents are funds held with FRB which fluctuate from period-to-period.

Certificates of deposit held in other financial institutions

As certificates of deposit held in other financial institutions mature, the funds are reinvested into AFS investment securities to increase net interest margins (as the yields on AFS investment securities exceeded the potential reinvestment rates for

Table of Contents

certificates of deposits held in other financial institutions during the year). While there were no maturities in 2014 to reinvest, the maturities in 2015 will likely continue this trend.

AFS investment securities

The primary objective of our investing activities is to provide for safety of the principal invested. Secondary considerations include the need for earnings, liquidity, and our overall exposure to changes in interest rates.

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

	2014	2013	2012	2011	2010
Government sponsored enterprises	$ 24,136	$ 23,745	$ 25,776	$ 397	$ 5,404
States and political subdivisions	215,345	201,988	182,743	174,938	169,717
Auction rate money market preferred	2,619	2,577	2,778	2,049	2,865
Preferred stocks	6,140	5,827	6,363	5,033	6,936
Mortgage-backed securities	166,926	144,115	155,345	143,602	102,215
Collateralized mortgage obligations	152,368	133,810	131,005	99,101	43,587
Total	$ 567,534	$ 512,062	$ 504,010	$ 425,120	$ 330,724

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. We have a policy prohibiting investments in securities that we deem 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. Our holdings in mortgage-backed securities and collateralized mortgage obligations include only government agencies and government sponsored agencies as we hold no investments in private label mortgage-backed securities or collateralized mortgage obligations.

Table of Contents

The following is a schedule of maturities of AFS investment securities and their weighted average yield as of December 31, 2014 . Weighted average yields have been computed on an FTE basis using a tax rate of 34% . Our auction rate money market preferred is a long term floating rate instrument for which the interest rate is set at periodic auctions. At each successful auction, we have 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. Because of their lack of contractual maturities, auction rate money market preferred and preferred stocks are not reported by a specific maturity group. Mortgage-backed securities and collateralized mortgage obligations are not reported by a specific maturity group due to their variable monthly payments. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations.

	Maturing — Within One Year		After One Year But Within Five Years		After Five Years But Within Ten Years		After Ten Years		Securities with Variable Monthly Payments or Noncontractual Maturities
	Amount	Yield (%)	Amount	Yield (%)	Amount	Yield (%)	Amount	Yield (%)	Amount	Yield (%)

Loans

Loans are the largest component of earning assets. The proper management of credit and market risk inherent in the loan portfolio is critical to our financial well-being. To control these risks, we have adopted strict underwriting standards. These standards include specific criteria against lending outside our defined market areas, lending limits to a single borrower, and strict loan to collateral value limits. We also monitor and limit loan concentrations to specific industries. We have 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 :

	2014	2013	2012	2011	2010
Commercial	$ 431,961	$ 392,104	$ 371,505	$ 365,714	$ 348,852

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

	2014 — $ Change		% Change		2013 — $ Change		% Change		2012 — $ Change	% Change
Commercial	$ 39,857		10.16	%	$ 20,599		5.54	%	$ 5,791	1.58 %

Total	$ 25,545		3.16	%	$ 35,284		4.57	%	$ 22,462	2.99 %

We continue to see declines in residential real estate loans which have been offset by increases in commercial and agricultural loans. This trend is likely to continue as the demand for residential real estate loans is anticipated to remain soft due to continuing uncertainty in the residential real estate markets, increases in interest rates, and the implementation of CFPB underwriting guidelines. We expect loans to increase moderately in 2015, with most of the growth in commercial loans.

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 unconsolidated entities accounted for under the equity method of accounting (see “ Note 1 – Nature of Operations and Summary of Significant Accounting Policies ” and “ Note 19 – Fair Value ” of the “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data ).

Deposits

Deposits are our primary source of funding. The following table presents the composition of the deposit portfolio as of December 31 :

	2014	2013	2012	2011	2010
Noninterest bearing demand deposits	$ 181,826	$ 158,428	$ 143,735	$ 119,072	$ 104,902
Interest bearing demand deposits	190,984	192,089	181,259	163,653	142,259
Savings deposits	261,412	243,237	228,338	193,902	177,817
Certificates of deposit	339,824	362,473	376,790	395,777	386,435

Total	$ 1,074,484	$ 1,043,766	$ 1,017,667	$ 958,164	$ 877,339

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

	2014 — $ Change		% Change		2013 — $ Change		% Change		2012 — $ Change		% Change
Noninterest bearing demand deposits	$ 23,398		14.77	%	$ 14,693		10.22	%	$ 24,663		20.71	%
Interest bearing demand deposits	(1,105	)	(0.58	)%	10,830		5.97	%	17,606		10.76	%
Savings deposits	18,175		7.47	%	14,899		6.52	%	34,436		17.76	%
Certificates of deposit	(22,649	)	(6.25	)%	(14,317	)	(3.80	)%	(18,987	)	(4.80	)%
Brokered certificates of deposit	15,805		28.06	%	981		1.77	%	1,022		1.88	%
Internet certificates of deposit	(2,906	)	(9.31	)%	(987	)	(3.07	)%	763		2.43	%
Total	$ 30,718		2.94	%	$ 26,099		2.56	%	$ 59,503		6.21	%

Overall, deposits continued to grow during 2014. As a result of the current interest rate environment, we continue to see declines in certificates of deposits, but these declines have been offset by increases in noninterest bearing demand deposits and savings accounts. We expect this trend to continue for the foreseeable future. Growth is anticipated to continue to come in the form of non-contractual deposits, while certificates of deposit are expected to approximate current levels.

The remaining maturity of time certificates and other time deposits of $100 or more as of December 31, 2014 was as follows:

Maturity
Within 3 months	$ 42,416
Within 3 to 6 months	22,303
Within 6 to 12 months	55,257
Over 12 months	124,924
Total	$ 244,900

Borrowed Funds

Borrowed funds include FHLB advances and securities sold under agreements to repurchase. The balance of borrowed funds fluctuates from period to period based on our funding needs including changes in loans, investments, and deposits. The current interest rate environment has made it almost impossible to increase net interest income without increasing earning assets. As deposit growth has generally outpaced loan demand, we continue to deploy deposits into purchases of AFS securities to provide additional interest income. In addition to utilizing deposits, we also utilize borrowings and brokered deposits to fund earning assets.

The following table presents borrowed funds balances for the years ended December 31 :

	2014	2013	2012	2011	2010
FHLB advances	$ 192,000	$ 162,000	$ 152,000	$ 142,242	$ 113,423
Securities sold under agreements to repurchase without stated maturity dates	95,070	106,025	66,147	57,198	45,871

For additional disclosure related to borrowed funds, see “ Note 9 – Borrowed Funds ” of “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data .

Accrued interest payable and other liabilities

Included in accrued interest payable and other liabilities are obligations related to our defined benefit pension plan. Our liability related to the plan increased in 2014 as a result of changes in mortality tables and discount rates used to determine the current benefit obligation. For more information on the defined benefit pension plan, see " Note 16 – Benefit Plans " of the “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data ).

Contractual Obligations and Loan Commitments

We have various financial obligations, including contractual obligations and commitments, which may require future cash payments. The following schedule summarizes our non-cancelable obligations and future minimum payments as of December 31, 2014 :

Total contractual obligations	$ 991,436	$ 171,583	$ 133,451	$ 67,723	$ 1,364,193

We also have loan commitments that may impact liquidity. The following schedule summarizes our loan commitments and expiration dates by period as of December 31, 2014 . Commitments to grant loans include loans to be sold to the secondary market. Since many of these commitments historically have expired without being drawn upon, the total amount of these commitments does not necessarily represent our future cash requirements.

	Expiration Dates by Period — Due in One Year or Less	After One Year But Within Three Years	After Three Years But Within Five Years	After Five Years	Total
Unused commitments under lines of credit	$ 68,056	$ 27,330	$ 18,527	$ 3,022	$ 116,935

Capital

Capital consists solely of common stock, retained earnings, and accumulated other comprehensive income (loss). We are currently authorized to raise capital through dividend reinvestment, employee and director stock purchases, and shareholder stock purchases. Pursuant to these authorizations, we issued 182,755 shares or $4,227 of common stock during 2014 , and 149,191 shares or $3,618 of common stock in 2013 . We also offer the Directors Plan in which participants either directly purchase stock or purchase stock units through deferred fees, in lieu of cash payments. Pursuant to this plan, we increased shareholders’ equity by $495 and $554 during 2014 and 2013 , respectively.

We have approved a publicly announced common stock repurchase plan. Pursuant to this plan, we repurchased 135,630 shares or $3,122 of common stock compared to 98,014 shares for $2,375 during 2014 and 2013 , respectively. As of December 31, 2014 , we were authorized to repurchase up to an additional 151,766 shares of common stock.

There are no significant regulatory constraints placed on our capital. The FRB ’s current recommended minimum primary capital to assets requirement is 6.00%. Our primary capital to adjusted average assets, which consists of shareholders' equity plus the ALLL acquisition intangibles, was 8.59% as of December 31, 2014 .

Table of Contents

The FRB has established minimum risk based capital guidelines. Pursuant to these guidelines, a framework has been established that assigns risk weights to each category of on and off balance sheet items to arrive at risk adjusted total assets. Regulatory capital is divided by the risk adjusted assets with the resulting ratio compared to the minimum standard to determine whether a corporation has adequate capital. The minimum standard is 8.00% , of which at least 4.00% must consist of equity capital net of goodwill. The following table sets forth the percentages required under the Risk Based Capital guidelines and our values as of:

	2014	2013	Required
Equity Capital	14.08 %	13.67 %	4.00 %
Secondary Capital	1.10 %	1.25 %	4.00 %
Total Capital	15.18 %	14.92 %	8.00 %

Secondary capital includes only the ALLL . The percentage for the secondary capital under the required column is the maximum amount allowed from all sources.

The FRB and FDIC also prescribe minimum capital requirements for Isabella Bank. At December 31, 2014 , the Bank exceeded these minimum capital requirements. On July 2, 2013, the FRB published revised BASEL III Capital standards for banks. The rules redefine what is included or deducted from equity capital, changes risk weighting for certain on and off-balance sheet assets, increases the minimum required equity capital to be considered well capitalized, and introduces a capital cushion buffer. The rules, which will be gradually phased in between 2015 and 2019, are not expected to have a material impact on the Corporation but will require us to hold more capital than we have historically. For further information regarding the Bank’s capital requirements, see “ Note 15 – Minimum Regulatory Capital Requirements ” of the “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data .

Fair Value

We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. AFS securities and certain liabilities are recorded at fair value on a recurring basis. Additionally, from time-to-time , we may be required to record at fair value other assets on a nonrecurring basis, such as mortgage loans AFS , foreclosed assets, OMSR , and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write-downs of individual assets.

For further information regarding fair value measurements, see “ Note 1 – Nature of Operations and Summary of Significant Accounting Policies ” and “ Note 19 – Fair Value ” of the “Notes to Consolidated Financial Statements” in Item 8. Financial Statements and Supplementary Data .

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. We strive to achieve reasonable stability in the net interest margin through periods of changing interest rates. One tool we use to measure interest rate sensitivity is gap analysis. As shown in the table below, the gap analysis depicts our position for specific time periods and the cumulative gap as a percentage of total assets.

Fixed interest rate AFS 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 $172,432 as of December 31, 2014 , 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 $1,123 that are included in the 0 to 3 month time frame.

Savings and NOW accounts have no contractual maturity date and are believed by us to be predominantly noninterest rate sensitive. These accounts have been classified in the gap table according to their estimated withdrawal rates based upon our analysis of deposit decay over the past five years. We believe this decay experience is consistent with our expectation for the future. As of December 31, 2014 , we had a positive cumulative gap within one year. A positive gap position results when more assets, within a specified time frame, have the potential to mature or reprice than liabilities.

The following table shows the time periods and the amount of assets and liabilities available for interest rate repricing as of December 31, 2014 . The interest rate sensitivity information for investment securities is based on the expected prepayments and call dates versus stated maturities. For purposes of this analysis, nonaccrual loans and the ALLL are excluded.

Liquidity

Liquidity is monitored regularly by our 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.

Our primary sources of liquidity are cash and cash equivalents, certificates of deposit held in other financial institutions, and AFS securities. These categories totaled $587,440 or 37.91% of assets as of December 31, 2014 as compared to $554,725 or 37.15% as of December 31, 2013 . Liquidity is important for financial institutions because of their need to meet loan funding commitments, depositor withdrawal requests, and various other commitments including expansion of operations, investment opportunities, and payment of cash dividends. Liquidity varies significantly daily, based on customer activity.

Our primary source of funds is deposit accounts. We also have the ability to borrow from the FHLB , the FRB , and through various correspondent banks in the form of federal funds purchased and a line of credit. These funding methods typically carry a higher interest rate than traditional market deposit accounts. Some borrowed funds, including FHLB advances, FRB Discount Window advances, and repurchase agreements, require us to pledge assets, typically in the form AFS securities or loans as collateral. As of December 31, 2014 , we had available lines of credit of $112,301 .

The following table summarizes our sources and uses of cash for the years ended December 31 :

Quantitative and Qualitative Disclosures about Market Risk

Our primary market risks are interest rate risk and liquidity risk. We have no significant foreign exchange risk and do not utilize interest rate swaps or derivatives, except for interest rate locks and forward loan commitments, in the management of IRR . Any changes in foreign exchange rates or commodity prices would have an insignificant impact on our interest income and cash flows.

IRR is the exposure of our net interest income to changes in interest rates. IRR results from the difference in the maturity or repricing frequency of a financial institution's interest earning assets and its interest bearing liabilities. IRR is the fundamental method by which financial institutions earn income and create shareholder value. Excessive exposure to IRR could pose a significant risk to our earnings and capital.

The FRB has adopted a policy requiring us to effectively manage the various risks that can have a material impact on our safety and soundness. The risks include credit, interest rate, liquidity, operational, and reputational. We have policies, procedures, and internal controls for measuring and managing these risks. Specifically, our Funds Management policy and procedures include defining acceptable types and terms of investments and funding sources, liquidity requirements, limits on investments in long term assets, limiting the mismatch in repricing opportunity of assets and liabilities, and the frequency of measuring and reporting to our Board .

The primary technique to measure IRR is simulation analysis. Simulation analysis forecasts the effects on the balance sheet structure and net interest income under a variety of scenarios that incorporate changes in interest rates, the shape of yield curves, interest rate relationships, and loan prepayments. These forecasts are compared against net interest income projected in a stable interest rate environment. While many assets and liabilities reprice either at maturity or in accordance with their contractual terms, several balance sheet components demonstrate characteristics that require an evaluation to more accurately reflect their repricing behavior. Key assumptions in the simulation analysis include prepayments on loans, probable calls of investment securities, changes in market conditions, loan volumes and loan pricing, deposit sensitivity, and customer preferences. These assumptions are inherently uncertain as they are subject to fluctuation and revision in a dynamic environment. As a result, the simulation analysis cannot precisely forecast the impact of rising and falling interest rates on net interest income. Actual results will differ from simulated results due to many other factors, including changes in balance sheet components, interest rate changes, changes in market conditions, and management strategies.

Our interest rate sensitivity is estimated by first forecasting the next 12 and 24 months of net interest income under an assumed environment of a constant balance sheet and constant market interest rates (base case). We then compare the results of various

Table of Contents

simulation analyses to the base case. At December 31, 2014 , we projected the change in net interest income during the next 12 and 24 months assuming market interest rates were to immediately decrease by 100 basis points and increase by 100, 200, 300, and 400 basis points in a parallel fashion over the entire yield curve during the same time period. We did not project scenarios showing decreases in interest rates beyond 100 basis points as this is considered extremely unlikely given current interest rate levels. These projections were based on our assets and liabilities remaining static over the next 12 and 24 months, while factoring in probable calls and prepayments of certain investment securities and real estate residential and consumer loans. While it is extremely unlikely that interest rates would immediately increase to these levels, we feel that these extreme scenarios help us identify potential gaps and mismatches in the repricing characteristics of assets and liabilities. We regularly monitor our projected net interest income sensitivity to ensure that it remains within established limits.

The following table summarizes our interest rate sensitivity for 12 and 24 months as of:

	December 31, 2014
	12 Months								24 Months
Immediate basis point change assumption (short-term)	(100)		100	200	300		400		(100)		100	200	300		400

Immediate basis point change assumption (short-term)	(100)		100	200		300		400		(100)		100	200	300	400

Gap analysis, the secondary method to measure IRR , measures the cash flows and/or the earliest repricing of our interest bearing assets and liabilities. This analysis is useful for measuring trends in the repricing characteristics of the balance sheet. Significant assumptions are required in this process because of the embedded repricing options contained in assets and liabilities. Residential real estate and consumer loans allow the borrower to repay the balance prior to maturity without penalty, while commercial and agricultural loans have prepayment penalties. The amount of prepayments is dependent upon many factors, including the interest rate of a given loan in comparison to the current offering rates, the level of 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 cash flows from these assets. A significant portion of our securities are callable or have prepayment options. The call and prepayment options are more likely to be exercised in a period of decreasing interest rates. Savings and demand accounts may generally be withdrawn on request without prior notice. The timing of cash flows from these deposits is estimated based on historical experience. Certificates of deposit have penalties that discourage early withdrawals.

The following tables provide information about assets and liabilities that are sensitive to changes in interest rates as of December 31, 2014 and December 31, 2013 . The principal amounts of investments, loans, other interest earning assets, borrowings, and time deposits maturing were calculated based on the contractual maturity dates. Estimated cash flows for savings and NOW accounts are based on our estimated deposit decay rates.

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, 2014 and 2013 , 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, 2014 . We also have audited Isabella Bank Corporation’s internal control over financial reporting as of December 31, 2014 , based on criteria established in the Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Isabella Bank Corporation’s 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 corporation’s 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 corporation’s 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 corporation’s assets that could have a material effect on the consolidated financial statements.

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, 2014 and 2013 , and the consolidated results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2014 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, 2014 , based on the COSO criteria.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

( Dollars in thousands except per share amounts )

Note 1 – Nature of Operations and Summary of Significant Accounting Policies

BASIS OF PRESENTATION AND CONSOLIDATION: The consolidated financial statements include the accounts of Isabella Bank Corporation, a financial services holding company, and its wholly owned subsidiary, Isabella Bank. 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. Our banking subsidiary, Isabella Bank, offers banking services through 27 locations, 24 hour banking services locally and nationally through shared automatic teller machines, 24 hour online banking, mobile banking, and direct deposits to businesses, institutions, and individuals. Lending services offered include commercial loans, agricultural loans, residential real estate loans, and consumer loans. 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 our principal markets. Our results of operations can be significantly affected by changes in interest rates or changes in the local economic environment.

For additional information, see “ Note 18 – Related Party Transactions .”

USE OF ESTIMATES: In preparing consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, we 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 ALLL , the fair value of AFS investment securities, and the valuation of goodwill and other intangible assets.

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 entity’s own data. We may choose to measure eligible items at fair value at specified election dates.

For assets and liabilities recorded at fair value, it is our 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, we include 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.

We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Investment securities AFS are recorded at fair value on a recurring basis. Additionally, from time-to-time , we may be required to record other assets and liabilities at fair value on a nonrecurring basis, such as mortgage loans AFS , impaired loans, foreclosed assets, OMSR , 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.

Table of Contents

Fair Value Hierarchy

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

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

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. Transfers between measurement levels are recognized at the end of reporting periods.

For further discussion of fair value considerations, refer to “ Note 19 – Fair Value .”

SIGNIFICANT GROUP CONCENTRATIONS OF CREDIT RISK : Most of our activities conducted are with customers located within the central Michigan area. A significant amount of our 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 P1D period. We maintain deposit accounts in various financial institutions which generally exceed federally insured limits or are not insured. We do not believe we are 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 with terms of three years or less and are carried at cost.

AFS SECURITIES: Purchases of investment securities are generally classified as AFS . However, we may elect to classify securities as either held to maturity or trading. Securities classified as AFS 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. Included in AFS securities are auction rate money market preferreds and preferred stocks. These investments are considered equity securities for federal income tax purposes, and as such, no estimated federal income tax impact is expected or recorded. Auction rate money market preferred securities and preferred stocks are recorded at fair value, with unrealized gains and losses 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 AFS securities are determined using the specific identification method.

AFS securities are reviewed quarterly for possible OTTI . In determining whether an OTTI exists for debt securities, we assert that: (a) we do not have the intent to sell the security; and (b) it is more likely than not we will not have to sell the security before recovery of its cost basis. If these conditions are not met, we recognize an OTTI charge through earnings for the difference between the debt security’s 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 we do not expect to recover the security’s amortized cost basis, the security is considered other-than-temporarily impaired. For these debt securities, we separate 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, we calculate the recovery value by performing a discounted cash flow analysis based on the current cash flows and future cash flows we expect to recover. The amount of the total OTTI related to the credit risk is recognized in earnings and is included in noninterest income. The amount of the total OTTI related to other risk factors is recognized as a component of other comprehensive income. For debt securities that have recognized an OTTI 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.

AFS equity securities are reviewed for OTTI 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 our ability and intent to hold the securities until fair value recovers. If it is determined that we

Table of Contents

do 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.

LOANS: Loans that we have 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 ALLL , 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 level yield method.

The accrual of interest on agricultural, commercial and mortgage 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. Consumer 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 nonaccrual 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 ALLL . 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 ALLL 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 we believe the uncollectability of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance.

We evaluate the ALLL on a regular basis and is based upon our periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.

The ALLL 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 we believe affect our 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 charge-off of its principal balance;
The loan has been classified as a TDR ; or
The loan is in nonaccrual status.

Impairment is measured on a loan by loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s 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.

LOANS HELD FOR SALE: Mortgage loans held for sale on 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, would be recognized as a component of other noninterest expenses.

Mortgage loans held for sale are sold with the mortgage servicing rights retained by us. 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 mortgage loans 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 us, 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) we do not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Other than servicing, we have no substantive continuing involvement related to these loans.

SERVICING: Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of financial assets. We have 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 we later determine 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. The unpaid principal balance of mortgages serviced for others was $288,639 and $293,665 with capitalized servicing rights of $2,519 and $2,555 at December 31, 2014 and 2013 , respectively.

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. We recorded servicing fee revenue of $720 , $737 , and $757 related to residential mortgage loans serviced for others during 2014 , 2013 , and 2012 , respectively, which is included in other noninterest income.

FORECLOSED ASSETS: Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at the lower of our 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 asset’s fair value at the date of acquisition are charged to the ALLL . 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. We periodically perform valuations 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 our carrying amount or fair value less costs to sell. Foreclosed assets of $885 and $1,412 as of December 31, 2014 and 2013 , respectively, are included in other assets.

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. We annually review these assets to determine whether carrying values have been impaired.

EQUITY SECURITIES WITHOUT READILY DETERMINABLE FAIR VALUES: Included in equity securities without readily determinable fair values are our holdings in FHLB stock and FRB stock as well as our ownership interests in Corporate Settlement Solutions, LLC and Valley Financial Corporation . Our investment in Corporate Settlement Solutions, LLC , a title insurance company, was made in the 1st quarter of 2008. We are not the managing entity of Corporate Settlement Solutions, LLC , and account for our investment in that entity under the equity method of accounting. Valley Financial Corporation is the parent company of 1st State Bank in Saginaw, Michigan, which is a bank that opened in 2005. We made investments in Valley Financial Corporation in 2004 and in 2007 .

EQUITY COMPENSATION PLAN: At December 31, 2014 , the Directors Plan had 187,369 shares eligible to be issued to participants, for which the Rabbi Trust held 13,934 shares. We had 185,311 shares to be issued in 2013 , with 12,761 shares held in the Rabbi Trust . Compensation costs relating to share based payment transactions are recognized as the services are rendered, with the cost measured based on the fair value of the equity or liability instruments issued (see “ Note 16 – Benefit Plans ”). We have no other equity-based compensation plans.

CORPORATE OWNED LIFE INSURANCE: We have purchased life insurance policies on key members of management. In the event of death of one of these individuals, we 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.

As of December 31, 2014 and 2013 , the present value of the post retirement benefits payable by us to the covered employees was estimated to be $2,782 and $2,699 , respectively, and is included in accrued interest payable and other liabilities. The periodic policy maintenance costs were $83 , $75 , and $24 for 2014 , 2013 , and 2012 , respectively and is included in other noninterest expenses.

ACQUISITION INTANGIBLES AND GOODWILL: We 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 goodwill and other intangible assets are being amortized over their estimated lives and evaluated for potential impairment on at least an annual basis. Goodwill represents the excess of purchase price over identifiable assets, is not amortized but is evaluated for impairment on at least an annual basis. Acquisition intangibles and goodwill are typically qualitatively evaluated to determine if it is more likely than not that the carrying balance is impaired. If it is determined that the carrying balance is more likely than not to be impaired, we perform a cash flow valuation to determine the extent of the potential impairment. This valuation method requires a significant degree of our judgment. In the event the projected undiscounted net operating cash flows for these intangible assets are less than the carrying value, the asset is recorded at fair value as determined by the valuation model.

OFF BALANCE SHEET CREDIT RELATED FINANCIAL INSTRUMENTS: In the ordinary course of business, we have 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. Valuation 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.

We analyze our filing positions in the jurisdictions where we are required to file income tax returns, as well as all open tax years in these jurisdictions. We have also elected to retain our existing accounting policy with respect to the treatment of interest and penalties attributable to income taxes, and continue to reflect any charges for such, to the extent they arise, as a component of our noninterest expenses.

DEFINED BENEFIT PENSION PLAN: We maintain a noncontributory defined benefit pension plan, which was curtailed effective March 1, 2007. Defined benefit pension plan expenses are included in “compensation and benefits" on the consolidated statements of income and are funded consistent with the requirements of federal laws and regulations. The current benefit obligation is included in "accrued interest payable and other liabilities" on the consolidated balance sheets. Inherent in the determination of defined benefit pension costs are assumptions concerning future events that will affect the amount and timing of required benefit payments under the plan. These assumptions include demographic assumptions such as mortality, a discount rate used to determine the current benefit obligation and a long-term expected rate of return on plan assets. Net

Table of Contents

periodic benefit cost includes interest cost based on the assumed discount rate, an expected return on plan assets based on an actuarially derived market-related value of assets, and amortization of unrecognized net actuarial gains or losses. Actuarial gains and losses result from experience different from that assumed and from changes in assumptions (excluding asset gains and losses not yet reflected in market-related value). Amortization of actuarial gains and losses is included as a component of net periodic defined benefit pension cost.

For additional information, see " Note 16 – Benefit Plans ."

MARKETING COSTS: Marketing costs are expensed as incurred (see “ Note 10 – Other Noninterest Expenses ”).

RECLASSIFICATIONS: Certain amounts reported in the 2013 and 2012 consolidated financial statements have been reclassified to conform with the 2014 presentation.

Note 2 – Computation of Earnings Per Common Share

Basic earnings per common share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per common share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued. Potential common shares that may be issued relate solely to outstanding shares in the Directors Plan , see “ Note 16 – Benefit Plans .”

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

	2014	2013	2012
Average number of common shares outstanding for basic calculation	7,734,161	7,694,392	7,604,303
Average potential effect of common shares in the Directors Plan (1)	171,393	168,948	195,063
Average number of common shares outstanding used to calculate diluted earnings per common share	7,905,554	7,863,340	7,799,366
Net income	$ 13,724	$ 12,510	$ 12,206

Note 3 – Pending Accounting Standards Updates

ASU No. 2014-01: “Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force)”

In January 2014, ASU No. 2014-01 amended ASC Topic 323, “Investments" to allow investors in low income housing tax credits to use the proportional amortization method if the following criteria are met:

• It is probable that the tax credits allocable to the investor will be available.

• The investor does not have the ability to exercise significant influence over the operating and financial policies of the limited liability entity.

• Substantially all of the projected benefits are from tax credits and other tax benefits (e.g., operating losses).

• The investor’s projected yield is based solely on the cash flows from the tax credits and other tax benefits are positive.

• The investor is a limited liability investor in the limited liability entity for both legal and tax purposes, and the investor’s liability is limited to its capital investment.

Investors that do not meet the above criteria must utilize the cost method or equity method in accordance with previously issued authoritative accounting guidance. The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2014 and is not expected to have a significant impact on our operations.

ASU No. 2014-04: “Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force)”

In January 2014, ASU No. 2014-04 amended ASC Topic 310, “Receivables” to reduce diversity by clarifying when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be

Table of Contents

derecognized and the real estate property recognized. The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2014 and is not expected to have a significant impact on our operations.

ASU No. 2014-09: “Revenue from Contracts with Customers”

In May 2014, ASU No. 2014-09 created new Topic 606 to provide a common revenue standard to achieve consistency and clarification to the revenue recognition principles. The guidance outlines steps to achieve the core principle which states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. These steps consist of: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2016 and is not expected to have a significant impact on our operations.

ASU No. 2014-11: “Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures”

In June 2014, ASU No. 2014-11 amended ASC Topic 860, “Transfers and Servicing” to address concerns that current accounting guidance distinguishes between repurchase agreements that settle at the same time as the maturity of the transferred financial asset and those that settle any time before maturity. The update changes the accounting for repurchase-to-maturity transactions to secured borrowing accounting and, for repurchase financing arrangements, separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2014 and is not expected to impact our financial statement disclosures.

ASU No. 2014-14: “Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force)”

In August 2014, ASU No. 2014-14 amended ASC Topic 310, “Receivables” to provide specific guidance on how to classify and measure foreclosed loans that are government guaranteed. The update requires that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met:

• The loan has a government guarantee that is not separable from the loan before foreclosure.

• At the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim.

• At the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed.

Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2014 and is not expected to have a significant impact on our operations.

ASU No. 2014-15: “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”

In August 2014, ASU No. 2014-15 amended ASC Topic 205, “Presentation of Financial Statements” to provide guidance on how to determine whether to disclose relevant conditions or events that raise substantial doubt about the entity's ability to continue as a going concern. If conditions or events raise substantial doubt about an entity’s ability to continue as a going concern, financial statements would continue to be prepared under the going concern assumption; however, disclosures may be necessary depending upon the conditions or events raising substantial doubt. Additionally, if identified substantial doubt is not alleviated after consideration of management’s plans, an entity should include a statement in the footnotes indicating that there is substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or available to be issued). The new authoritative guidance is effective for annual and interim periods beginning after December 15, 2016 and is not expected to impact our financial statement disclosures.

Expected maturities for government sponsored enterprises and states and political subdivisions may differ from contractual maturities because issuers may have the right to call or prepay obligations.

As the auction rate money market preferred and preferred stocks have continual call dates, they are not reported by a specific maturity group. Because of their variable monthly payments, mortgage-backed securities and collateralized mortgage obligations are not reported by a specific maturity group.

Number of securities in an unrealized loss position:		182		19	201

As of December 31, 2014 and 2013 , we conducted an analysis to determine whether any securities currently in an unrealized loss position, should be other-than-temporarily impaired. Such analyses considered, among other factors, the following criteria:

• Has the value of the investment declined more than what is deemed to be reasonable based on a risk and maturity adjusted discount rate?

• Is the investment credit rating below investment grade?

• Is it probable the issuer will be unable to pay the amount when due?

• Is it more likely than not that we will have to sell the security before recovery of its cost basis?

• Has the duration of the investment been extended?

During the three month period ended March 31, 2012 , we had one state issued student loan auction rate AFS investment security (which is included in states and political subdivisions) that was downgraded by Moody's from A3 to Caa3 . As a result of this downgrade, we engaged the services of an independent investment valuation firm to estimate the amount of credit losses

Table of Contents

(if any) related to this particular issue as of March 31, 2012 . The evaluation calculated a range of estimated credit losses utilizing two different bifurcation methods:

1) Discounted Cash Flow Method

2) Credit Yield Analysis Method

The two methods were then weighted, with a higher weighting applied to the Discounted Cash Flow Method , to determine the estimated credit related impairment. As a result of this analysis, we recognized an OTTI of $282 in earnings in the three month period ended March 31, 2012 .

A summary of key valuation assumptions used in the aforementioned analysis as of March 31, 2012 , follows:

	Discounted Cash Flow Method
Ratings
Fitch	Not Rated
Moody's	Caa3
S&P	A
Seniority	Senior
Discount rate	LIBOR + 6.35%
	Credit Yield Analysis Method
Credit discount rate	LIBOR + 4.00%
Average observed discounts based on closed transactions	14.00%

To test for additional impairment of this security as of December 31, 2014 , we obtained another investment valuation (from the same firm engaged to perform the initial valuation as of March 31, 2012 ) as of December 31, 2014 . Based on our analysis, no additional OTTI was indicated as of December 31, 2014 .

The following table provides a roll-forward of credit related impairment recognized in earnings for the years ended December 31 :

	2014	2013	2012
Balance at beginning of year	$ 282	$ 282	$ —
Additions to credit losses for which no previous OTTI was recognized	—	—	282
Balance at end of year	$ 282	$ 282	$ 282

Based on our analyses, the fact that we have asserted that we do not have the intent to sell AFS securities in an unrealized loss position, and considering it is unlikely that we will have to sell AFS securities in an unrealized loss position before recovery of their cost basis, we do not believe that the values of any AFS securities are other-than-temporarily impaired as of December 31, 2014 , or December 31, 2013 .

Note 5 – Loans and ALLL

We grant commercial, agricultural, residential real estate, and consumer loans to customers situated primarily in Clare, Gratiot, Isabella, Mecosta, Midland, Montcalm, and Saginaw counties in Michigan. The ability of the borrowers to honor their repayment obligations is often dependent upon the real estate, agricultural, light manufacturing, retail, gaming, tourism, higher education, and general economic conditions of this region. Substantially all of our consumer and residential real estate loans are secured by various items of property, while commercial loans are secured primarily by real estate, business assets, and personal guarantees; a portion of loans are unsecured.

Loans that we have the intent and ability to hold in our portfolio are reported at their outstanding principal balance adjusted for any charge-offs , the ALLL , and any deferred fees or costs. Interest income is accrued over the term of the loan based on the principal amount outstanding. Loan origination fees and certain direct loan origination costs are capitalized and recognized as a component of interest income over the term of the loan using the level yield method.

The accrual of interest on commercial, agricultural, and residential real estate loans is typically 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. Upon transferring the loans

Table of Contents

to nonaccrual status, we perform an evaluation to determine the net realizable value of the underlying collateral. This evaluation is used to help determine if any charge-offs are necessary. Consumer 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 nonaccrual 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 ALLL . Loans are typically returned to accrual status after six months of continuous performance. 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.

Commercial and agricultural loans include loans for commercial real estate, commercial operating loans, farmland and agricultural production, and states and political subdivisions. Repayment of these loans is often dependent upon the successful operation and management of a business. We minimize our risk by limiting the amount of credit exposure to any one borrower to $15,000 . Borrowers with credit needs of more than $15,000 are serviced through the use of loan participations with other commercial banks. Commercial and agricultural real estate loans generally require loan-to-value limits of less than 80% . Depending upon the type of loan, past credit history, and current operating results, we may require the borrower to pledge accounts receivable, inventory, and property and equipment. Personal guarantees are generally required from the owners of closely held corporations, partnerships, and sole proprietorships. In addition, we require annual financial statements, prepare cash flow analyses, and review credit reports as deemed necessary.

We offer adjustable rate mortgages, construction loans, and fixed rate residential real estate loans which typically have amortization periods up to a maximum of 30 years. Fixed rate residential real estate loans with an amortization of greater than 15 years are generally sold upon origination to Freddie Mac . Fixed rate residential real estate loans with an amortization of 15 years or less may be held in our portfolio or sold to Freddie Mac upon origination. We consider the direction of interest rates, the sensitivity of our balance sheet to changes in interest rates, and overall loan demand to determine whether or not to sell these loans to Freddie Mac .

Our lending policies generally limit the maximum loan-to-value ratio on residential real estate loans 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 borrower’s 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 borrower’s 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 and reviewed internally. All mortgage loan requests are reviewed by our mortgage loan committee or through a secondary market automated underwriting system; loans in excess of $500 require the approval of our Internal Loan Committee, the Executive Loan Committee, the Board of Directors’ Loan Committee, or the Board of Directors.

Consumer loans include secured and unsecured personal loans. Loans are amortized for a period of up to 12 years based on the age and value of the underlying collateral. The underwriting emphasis is on a borrower’s perceived intent and ability to pay rather than collateral value. No consumer loans are sold to the secondary market.

The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the ALLL when we believe the uncollectability of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the ALLL .

The ALLL is evaluated on a regular basis and is based upon a periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.

The primary factors behind the determination of the level of the ALLL are specific allocations for impaired loans, historical loss percentages, as well as unallocated components. Specific allocations for impaired loans are primarily determined based on the difference between the loan’s outstanding balance to the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral, less cost to sell. Historical loss allocations were calculated at the loan class and segment levels based on a migration analysis of the loan portfolio over the preceding five years. An unallocated component is maintained to cover uncertainties that we believe affect our 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.

Internally assigned credit risk ratings are reviewed, at a minimum, when loans are renewed or when management has knowledge of improvements or deterioration of the credit quality of individual credits. Descriptions of the internally assigned credit risk ratings for commercial and agricultural loans are as follows:

1. EXCELLENT – Substantially Risk Free

Credit has strong financial condition and solid earnings history, characterized by:

• High liquidity, strong cash flow, low leverage.

• Unquestioned ability to meet all obligations when due.

• Experienced management, with management succession in place.

• Secured by cash.

2. HIGH QUALITY – Limited Risk

Credit with sound financial condition and has a positive trend in earnings supplemented by:

• Favorable liquidity and leverage ratios.

• Ability to meet all obligations when due.

• Management with successful track record.

• Steady and satisfactory earnings history.

• If loan is secured, collateral is of high quality and readily marketable.

• Access to alternative financing.

• Well defined primary and secondary source of repayment.

• If supported by guaranty, the financial strength and liquidity of the guarantor(s) are clearly evident.

Table of Contents

3. HIGH SATISFACTORY – Reasonable Risk

Credit with satisfactory financial condition and further characterized by:

• Working capital adequate to support operations.

• Cash flow sufficient to pay debts as scheduled.

• Management experience and depth appear favorable.

• Loan performing according to terms.

• If loan is secured, collateral is acceptable and loan is fully protected.

4. LOW SATISFACTORY – Acceptable Risk

Credit with bankable risks, although some signs of weaknesses are shown:

• Would include most start-up businesses.

• Occasional instances of trade slowness or repayment delinquency – may have been 10 - 30 days slow within the past year.

• Management’s abilities are apparent, yet unproven.

• Weakness in primary source of repayment with adequate secondary source of repayment.

• Loan structure generally in accordance with policy.

• If secured, loan collateral coverage is marginal.

• 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.

5. SPECIAL MENTION – Criticized

Credit constitutes an undue and unwarranted credit risk but not to the point of justifying a classification of substandard. The credit risk may be relatively minor yet 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.

• Collateral or guaranty offers limited protection.

• Negative debt service coverage, however the credit is well collateralized and payments are current.

6. SUBSTANDARD – Classified

Credit where the borrower’s current net worth, paying capacity, and value of the collateral pledged is inadequate. There is a distinct possibility that we 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.

Table of Contents

7. VULNERABLE – Classified

Credit is considered “Substandard” and warrants 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.

8. DOUBTFUL – Workout

Credit has all the weaknesses inherent in a “Substandard” loan with the added characteristic that collection and/or liquidation is pending. The possibility of a loss is extremely high, but its classification as a loss is deferred until liquidation procedures are completed, or reasonably estimable. Other characteristics that may apply:

• Normal operations are severely diminished or have ceased.

• Seriously impaired cash flow.

• Original repayment terms materially altered.

• Secondary source of repayment is inadequate.

• Survivability as a “going concern” is impossible.

• Collection process has begun.

• Bankruptcy petition has been filed.

• Judgments have been filed.

• Portion of the loan balance has been charged-off .

Impaired Loans

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

There has been a charge-off of its principal balance (in whole or in part);
The loan has been classified as a TDR ; or
The loan is in nonaccrual status.

Impairment is measured on a loan-by-loan basis for commercial and agricultural loans by comparing the loan’s outstanding balance to the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s 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. Impairment is measured on a loan-by-loan basis for residential real estate and consumer loans by comparing the loan’s unpaid principal balance to the present value of expected future cash flows discounted at the loan’s effective interest rate.

Table of Contents

We do not recognize interest income on impaired loans in nonaccrual status. For impaired loans not in nonaccrual status, interest income is recognized daily, as earned, according to the terms of the loan agreement. The following is a summary of information pertaining to impaired loans as of, and for the years ended, December 31 :

As of December 31, 2014 and December 31, 2013 , we had committed to advance $0 and $134 , respectively, in connection with impaired loans, which include TDRs .

Troubled Debt Restructurings

Loan modifications are considered to be TDRs when the modification includes terms outside of normal lending practices to a borrower who is experiencing financial difficulties.

Typical concessions granted include, but are not limited to:

Agreeing to interest rates below prevailing market rates for debt with similar risk characteristics.
Extending the amortization period beyond typical lending guidelines for loans with similar risk characteristics.
Forgiving principal.
Forgiving accrued interest.

To determine if a borrower is experiencing financial difficulties, factors we consider include:

The borrower is currently in default on any of their debt.
The borrower would likely default on any of their debt if the concession was not granted.
The borrower’s cash flow was insufficient to service all of their debt if the concession was not granted.
The borrower has declared, or is in the process of declaring, bankruptcy.
The borrower is unlikely to continue as a going concern (if the entity is a business).

We did not restructure any loans by forgiving principal or accrued interest during 2014 or 2013 .

Based on our historical loss experience, losses associated with TDRs are not significantly different than other impaired loans within the same loan segment. As such, TDRs , including TDRs that have been modified in the past 12 months that subsequently defaulted, are analyzed in the same manner as other impaired loans within their respective loan segment.

Table of Contents

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for federal income tax purposes. Significant components of our deferred tax assets and liabilities, included in other assets in the accompanying consolidated balance sheets, are as follows as of December 31 :

	2014	2013

Other	449	547
Total deferred tax liabilities	5,302	3,290
Net deferred tax assets	$ 4,891	$ 7,898

We are subject to U.S. federal income tax; however, we are no longer subject to examination by taxing authorities for years before 2011 . There are no material uncertain tax positions requiring recognition in our consolidated financial statements . We do not expect the total amount of unrecognized tax benefits to significantly increase in the next twelve months.

We recognize interest and/or penalties related to income tax matters in income tax expense. We do not have any amounts accrued for interest and penalties at December 31, 2014 and 2013 and we not aware of any claims for such amounts by federal income tax authorities.

Note 12 – Off-Balance-Sheet Activities

Credit-Related Financial Instruments

We are party to credit related financial instruments with off-balance-sheet risk. These financial instruments are entered into in the normal course of business to meet the financing needs of our customers. These financial instruments, which include commitments to extend credit and standby letters of credit, involve, to varying degrees, elements of credit and IRR in excess of the amounts recognized in the consolidated balance sheets. The contract or notional amounts of these instruments reflect the extent of involvement we have in a particular class of financial instrument.

	December 31 — 2014	2013
Unfunded commitments under lines of credit	$ 116,935	$ 121,959
Commercial and standby letters of credit	4,985	4,169
Commitments to grant loans	13,988	29,096

Unfunded commitments under lines of credit are commitments for possible future extensions of credit to existing customers. These commitments may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements.

Table of Contents

Commercial and standby letters of credit are conditional commitments we issued 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. We evaluate each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if we deem necessary upon the extension of credit, is based on our credit evaluation of the borrower. While we consider 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 grant loans 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 amount of collateral obtained, if we deem necessary, is based on our credit evaluation of the customer. Commitments to grant loans include loans committed to be sold to the secondary market.

Our 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 could be up to the contractual notional amount of those instruments. We use the same credit policies in deciding to make these commitments as we do for extending loans to customers. No significant losses are anticipated as a result of these commitments.

Note 13 – On-Balance Sheet Activities

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. We enter 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 us 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 us 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 increase. The notional amount of undesignated interest rate lock commitments was $ 632 and $ 182 at December 31, 2014 and 2013 , respectively.

Forward Loan Sale Commitments

To protect against the price risk inherent in derivative loan commitments, we utilize 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, we commit to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. If we fail to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, we are 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, we commit 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).

We expect 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 $ 1,533 and $ 1,286 at December 31, 2014 and 2013 , 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 our consolidated financial statements .

Note 14 – Commitments and Other Matters

Banking regulations require us to maintain cash reserve balances in currency or as deposits with the FRB . At December 31, 2014 and 2013 , the reserve balances amounted to $ 963 and $ 910 , 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, 2014 , substantially all of the Bank’s 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 year’s retained net income plus retained net income for the preceding two years, less any required transfers to common stock. At January 1, 2015 , the amount available to the Corporation for dividends from the Bank, without regulatory approval, was approximately $ 22,800 .

Note 15 – Minimum Regulatory Capital Requirements

The Corporation (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the FRB and the FDIC . Failure to meet minimum capital requirements can initiate mandatory and possibly additional discretionary actions by the FRB and the FDIC that if undertaken, could have a material effect on our financial statements. Under regulatory capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that include quantitative measures of assets, liabilities, capital, and certain off-balance-sheet items, as calculated under regulatory accounting standards. Our capital amounts and classifications are also subject to qualitative judgments by the FRB and the FDIC 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 us 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). We believe, as of December 31, 2014 and 2013 , that we met all capital adequacy requirements.

As of December 31, 2014 , the most recent notifications from the FRB and the FDIC categorized us 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 we believe has changed our categories. Our actual capital amounts and ratios are also presented in the table.

Note 16 – Benefit Plans

401(k) Plan

We have a 401(k) plan in which substantially all employees are eligible to participate. Employees may contribute up to 100% of their compensation subject to certain limits based on federal tax laws. The plan was amended in 2013 to provide a matching safe harbor contribution for all eligible employees equal to 100% of the first 5.0% of an employee's compensation contributed to the Plan during the year. Employees are 100% vested in the safe harbor matching contributions.

For 2014 , 2013 and 2012 , expenses attributable to the Plan were $ 655 , $ 608 , and $ 662 , respectively.

Defined Benefit Pension Plan

We maintain a noncontributory defined benefit pension plan, which was curtailed effective March 1, 2007 . As a result of the curtailment, future salary increases are no longer considered (the projected benefit obligation is equal to the accumulated benefit obligation), and plan benefits are based on years of service and the individual employee’s five highest consecutive years of compensation out of the last ten years of service through March 1, 2007 .

Table of Contents

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

	2014		2013
Change in benefit obligation
Benefit obligation, January 1	$ 10,732		$ 12,209
Interest cost	486		450
Actuarial (gain) loss	3,049		(1,294	)
Benefits paid, including plan expenses	(1,017	)	(633	)
Benefit obligation, December 31	13,250		10,732
Change in plan assets
Fair value of plan assets, January 1	10,508		9,650
Investment return	699		1,276
Contributions	200		215
Benefits paid, including plan expenses	(1,017	)	(633	)
Fair value of plan assets, December 31	10,390		10,508
Deficiency in funded status at December 31, included on the consolidated balance sheets in accrued interest payable and other liabilities	$ (2,860	)	$ (224	)

	2014		2013
Change in accrued pension benefit costs
Accrued benefit cost at January 1	$ (224	)	$ (2,559	)
Contributions	200		215
Net periodic benefit cost	(300	)	(208	)
Net change in unrecognized actuarial loss and prior service cost	(2,536	)	2,328
Accrued pension benefit cost at December 31	$ (2,860	)	$ (224	)

We have recorded the funded status of the Plan in our consolidated balance sheets. We adjust the underfunded status in a liability account to reflect the current funded status of the plan. Our liability increased in 2014 as a result of changes in mortality tables and discount rates used to determine the current benefit obligation. Any gains or losses that arise during the year but are not recognized as components of net periodic benefit cost are 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 :

Interest cost on benefit obligation	2014 — $ 486		2013 — $ 450		2012 — $ 470
Expected return on plan assets	(615	)	(572	)	(511	)
Amortization of unrecognized actuarial net loss	169		330		292
Settlement loss	260		—		—
Net periodic benefit cost	$ 300		$ 208		$ 251

During 2014, an additional settlement loss of $260 was recognized in connection with lump-sum benefits distributions. Many plan participants elect to receive their retirement benefit payments in the form of lump-sum settlements. Pro rata settlement losses, which can occasionally occur as a result of these lump sum distributions, are recognized only in years when the total of such distributions exceed the sum of the service and interest expense components of net periodic benefit cost.

Accumulated other comprehensive income at December 31, 2014 includes net unrecognized pension costs before income taxes of $ 5,770 , of which $ 241 is expected to be amortized into benefit cost during 2015 .

The actuarial assumptions used in determining the benefit obligation are as follows for the years ended December 31 :

	2014	2013	2012
Discount rate	3.80 %	4.64 %	3.75 %
Expected long-term rate of return	6.00 %	6.00 %	6.00 %

Table of Contents

The actuarial weighted average assumptions used in determining the net periodic pension costs are as follows for the years ended December 31 :

	2014	2013	2012
Discount rate	4.64 %	3.75 %	4.22 %
Expected long-term return on plan assets	6.00 %	6.00 %	6.00 %

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 long 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

Our 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 6.00% . 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 our pension committee, which is comprised of members of our management. To manage the Plan, we retain a third party investment advisor to conduct consultations. We review the performance of the advisor at least annually.

The fair values of our pension plan assets by asset category were as follows as of December 31 :

	2014 — Total	(Level 2)	2013 — Total	(Level 2)
Short-term investments	$ 804	$ 804	$ 142	$ 142
Common collective trusts
Fixed income	4,738	4,738	5,064	5,064
Equity investments	4,848	4,848	5,302	5,302
Total	$ 10,390	$ 10,390	$ 10,508	$ 10,508

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, 2014 and 2013 :

• 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 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.

We do not anticipate any contributions to the plan in 2015 .

The components of projected net periodic benefit cost are as follows for the year ending:

Interest cost on projected benefit obligation	December 31, 2015 — $ 493
Expected return on plan assets	(607	)
Amortization of unrecognized actuarial net loss	355
Net periodic benefit cost	$ 241

Table of Contents

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

	Estimated Benefit Payments
2015	$ 535
2016	526
2017	555
2018	559
2019	604
2020 - 2024	3,425

Equity Compensation Plan

Pursuant to the terms of the Directors Plan , our directors are required to invest at least 25% of their board fees in our common stock. These stock investments can be made either through deferred fees or through the purchase of shares through the Dividend Reinvestment Plan . Deferred fees, under the Directors Plan , are converted on a quarterly basis into shares of our common stock based on the fair value of a share of common stock as of the relevant valuation date. Stock credited to a participant’s account is eligible for stock and cash dividends as declared. Dividend Reinvestment Plan shares are purchased on a monthly basis pursuant to the Dividend Reinvestment Plan .

Distribution of deferred fees from the Directors Plan occurs when the participant retires from the Board or upon the occurrence of certain other events. The participant is eligible to receive 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 . We may also purchase shares of common stock on the open market to meet our obligations under the Directors Plan .

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

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

	2014 — Eligible Shares	Market Value	2013 — Eligible Shares	Market Value
Unissued	173,435	$ 3,902	172,550	$ 4,115
Shares held in Rabbi Trust	13,934	314	12,761	304
Total	187,369	$ 4,216	185,311	$ 4,419

Other Employee Benefit Plans

We maintain two nonqualified supplementary employee retirement plans to provide supplemental retirement benefits to specified participants. Expenses related to these programs for 2014 , 2013 and 2012 were $ 372 , $ 375 , and $ 382 , respectively, and are being recognized over the participants’ expected years of service.

We maintain a non-leveraged ESOP which was frozen to new participants on December 31, 2006. Contributions to the plan are discretionary and are approved by the Board of Directors and recorded as compensation expense. During 2012, the Board of Directors approved a contribution of $ 75 to the ESOP . We made no contributions in 2014 or 2013. Compensation cost related to the plan for 2014 , 2013 and 2012 was $23 , $ 29 , and $ 102 , respectively. Total allocated shares outstanding related to the ESOP at December 31, 2014 , 2013 , and 2012 were 241,958 , 241,958 , and 246,404 , respectively. Such shares are included in the computation of dividends and earnings per share in each of the respective years.

Table of Contents

We maintain a self-funded medical plan under which we are responsible for the first $ 75 per year of claims made by a covered family. Expenses are accrued based on estimates of the aggregate liability for claims incurred and our experience. Expenses were $ 1,786 in 2014 , $ 2,698 in 2013 and $ 2,534 in 2012 .

Note 17 – Accumulated Other Comprehensive Income (Loss)

AOCI includes net income as well as unrealized gains and losses, net of tax, on AFS investment securities owned and changes in the funded status of our defined benefit pension plan, which are excluded from net income. Unrealized AFS securities gains and losses and changes in the funded status of the pension plan, net of tax, are excluded from net income, and are reflected as a direct charge or credit to shareholders’ equity. Comprehensive income (loss) and the related components are disclosed in the consolidated statements of comprehensive income.

The following table summarizes the changes in AOCI by component for the years ended December 31 (net of tax):

Included in OCI for the years ended December 31, 2014 and 2013 are changes in unrealized holding gains and losses related to auction rate money market preferred and preferred stocks. For federal income tax purposes, these securities are considered equity investments. As such, no deferred federal income taxes related to unrealized holding gains or losses are expected or recorded.

Note 19 – Fair Value

Following is a description of the valuation methodologies, key inputs, and an indication of the level of the fair value hierarchy in which the assets or liabilities are classified.

Cash and cash equivalents : The carrying amounts of cash and demand deposits due from banks and interest bearing balances due from banks approximate fair values. As such, we classify cash and cash equivalents as Level 1.

Certificates of deposit held in other financial institutions : Certificates of deposit held in other 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. As such, we classify certificates of deposits held in other financial institutions as Level 2.

AFS securities: AFS securities are recorded at fair value on a recurring basis. Level 1 fair value measurement is based upon quoted prices for identical instruments. Level 2 fair value measurement is based upon quoted prices for similar instruments. If quoted prices are not available, fair values are measured using independent pricing models or other model based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss and liquidity assumptions. The values for Level 1 and Level 2 investment securities are generally obtained from an independent third party. On a quarterly basis, we compare the values provided to alternative pricing sources.

Mortgage loans AFS : Mortgage loans AFS are carried at the lower of cost or fair value. The fair value of Mortgage loans AFS are based on what price secondary markets are currently offering for portfolios with similar characteristics. As such, we classify Mortgage loans AFS subject to nonrecurring fair value adjustments as Level 2.

Table of Contents

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. As such, we classify loans as Level 3 assets.

We do not record loans at fair value on a recurring basis. However, from time-to-time , loans are classified as impaired and a specific allowance for loan losses may be established. Loans for which it is probable that payment of interest and principal will be significantly different than the contractual terms of the original loan agreement are considered impaired. Once a loan is identified as impaired, we measure the estimated impairment. The fair value of impaired loans is estimated using one of several methods, including the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral, less cost to sell, if the loan is collateral dependent. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans.

We review the net realizable values of the underlying collateral for collateral dependent impaired loans on at least a quarterly basis for all loan types. To determine the collateral value, we utilize independent appraisals, broker price opinions, or internal evaluations. We review these valuations to determine whether an additional discount should be applied given the age of market information that may have been considered as well as other factors such as costs to carry and sell an asset if it is determined that the collateral will be liquidated in connection with the ultimate settlement of the loan. We use these valuations to determine if any specific reserves or charge-offs are necessary. We may obtain new valuations in certain circumstances, including when there has been significant deterioration in the condition of the collateral, if the foreclosure process has begun, or if the existing valuation is deemed to be outdated.

The following tables list the quantitative fair value information about impaired loans as of December 31 :

Valuation Techniques	2014 — Fair Value	Unobservable Input	Range
		Discount applied to collateral appraisal:
		Real Estate	20% - 25%
		Equipment	30% - 40%
Discounted appraisal value	$8,720	Cash crop inventory	40%
		Other inventory	75%
		Accounts receivable	50%
		Liquor license	75%

Valuation Techniques	2013 — Fair Value	Unobservable Input	Range
		Discount applied to collateral appraisal:
		Real Estate	20% - 30%
		Equipment	50%
Discounted appraisal value	$13,902	Livestock	50%
		Cash crop inventory	50%
		Other inventory	75%
		Accounts receivable	75%

Discount factors with ranges are based on the age of the independent appraisal, broker price opinion, or internal evaluations.

Accrued interest receivable : The carrying amounts of accrued interest receivable approximate fair value. As such, we classify accrued interest receivable as Level 1.

Equity securities without readily determinable fair values : Included in equity securities without readily determinable fair values are FHLB stock and FRB stock as well as our ownership interests in Corporate Settlement Solutions, LLC and Valley Financial Corporation . The investment in Corporate Settlement Solutions, LLC , a title insurance company, was made in the first quarter 2008. We are not the managing entity of Corporate Settlement Solutions, LLC , and therefore, we account for our investment under the equity method of accounting. Valley Financial Corporation is the parent company of 1st State Bank in Saginaw, Michigan, which is a community bank that opened in 2005. We made investments in Valley Financial Corporation in 2004 and in 2007 .

The lack of an active market, or other independent sources to validate fair value estimates coupled with the impact of future capital calls and transfer restrictions, is an inherent limitation in the valuation process. As the fair values of these investments are not readily determinable, they are not disclosed under a specific fair value hierarchy; however, they are reviewed quarterly for impairment. If we were to record an impairment adjustment related to these securities, it would be classified as a nonrecurring Level 3 fair value adjustment. During 2014 and 2013 , there were no impairments recorded on equity securities without readily determinable fair values.

Foreclosed assets : Upon transfer from the loan portfolio, foreclosed assets (which are included in other 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 management’s estimation of the value of the collateral. Due to the inherent level of estimation in the valuation process, we record foreclosed assets as nonrecurring Level 3.

The table below lists the quantitative fair value information related to foreclosed assets as of:

Valuation Techniques	December 31, 2014 — Fair Value	Unobservable Input	Range
		Discount applied to collateral appraisal:
Discounted appraisal value	$ 885	Real Estate	20% - 25%

Valuation Techniques	December 31, 2013 — Fair Value	Unobservable Input	Range
		Discount applied to collateral appraisal:
Discounted appraisal value	$ 1,412	Real Estate	20% - 30%

Discount factors with ranges are based on the age of the independent appraisal, broker price opinion, or internal evaluations.

Goodwill and other intangible assets : Acquisition intangibles and goodwill are evaluated for potential impairment on at least an annual basis. Acquisition intangibles and goodwill are typically qualitatively evaluated to determine if it is more likely than not that the carrying balance is impaired. If it is determined that the carrying balance of acquisition intangibles or goodwill is more likely than not to be impaired, we perform a cash flow valuation to determine the extent of the potential impairment. If the testing resulted in impairment, we would classify goodwill and other acquisition intangibles subjected to nonrecurring fair value adjustments as Level 3. During 2014 and 2013 , there were no impairments recorded on goodwill and other acquisition intangibles.

OMSR : OMSR (which are included in other assets) are subject to impairment testing. To test for impairment, we utilize a discounted cash flow analysis using interest rates and prepayment speed assumptions currently quoted for comparable instruments and discount rates. If the valuation model reflects a value less than the carrying value, OMSR are adjusted to fair value through a valuation allowance as determined by the model. As such, we classify OMSR subject to nonrecurring fair value adjustments as Level 2.

Deposits : The fair value of demand, savings, and money market deposits are, by definition, equal their carrying amounts and are classified as Level 1. Fair values for variable rate certificates of deposit approximate their 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. As such, fixed rate certificates of deposit are classified as Level 2.

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 other borrowed funds are estimated using discounted cash flow analyses based on current incremental borrowing arrangements. As such, borrowed funds are classified as Level 2.

Accrued interest payable: The carrying amounts of accrued interest payable approximate fair value. As such, we classify accrued interest payable as Level 1.

Commitments to extend credit, standby letters of credit, and undisbursed loans: Our commitments to extend credit, standby letters of credit, and undisbursed funds have no carrying amount and are estimated to have no realizable fair value. Historically, a majority of the unused commitments to extend credit have not been drawn upon and, generally, we do not receive fees in connection with these commitments other than standby letter of credit fees, which are not significant.

The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Although we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement.

Estimated Fair Values of Financial Instruments Not Recorded at Fair Value in their Entirety on a Recurring Basis

Disclosure of the estimated fair values of financial instruments, which differ from carrying values, often requires the use of estimates. In cases where quoted market values in an active market are not available, we use present value techniques and other valuation methods to estimate the fair values of our financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used.
