ISABELLA BANK CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

NOTE 1 — BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring accruals with the exception of the fair value reporting election described in Note 6 and the adoption of EITF 06-4 described in Note 7) considered necessary for a fair presentation have been included. Operating results for the three and six month periods ended June 30, 2008 are not necessarily indicative of the results that may be expected for the year ending December 31, 2008. For further information, refer to the consolidated financial statements and footnotes thereto included in the Corporation’s annual report for the year ended December 31, 2007.

All amounts other than share and per share amounts have been rounded to the nearest thousand ($000) in this report.

Effective January 1, 2008, the Corporation acquired Greenville Community Financial Corporation (GCFC). The condensed consolidated financial statements include the results of operations of GCFC since January 1, 2008 (see Note 2). Effective March 1, 2008, the Corporation entered into a joint venture with Corporate Title Agency, LLC. The condensed consolidated financial statements include the results of operations from this new entity since March 1, 2008 (see Note 2). Refer to Management’s Discussion and Analysis for further consideration of the impact of these transactions on the condensed consolidated financial statements.

The accounting policies are the same as those discussed in Note 1 to the Consolidated Financial Statements included in the Corporation’s annual report for the year ended December 31, 2007, with the addition of new pronouncements adopted during 2008 (see Note 7).

NOTE 2 — BUSINESS COMBINATION AND JOINT VENTURE FORMATION

Bank Acquisition

On the opening of business on January 1, 2008, Isabella Bank Corporation acquired 100 percent of Greenville Community Financial Corporation (GCFC). As a result of this acquisition, Greenville Community Bank, a wholly owned subsidiary of GCFC, merged with and into Isabella Bank (the “Bank”). Under the terms of the merger agreement, each share of GCFC common stock was automatically converted into the right to receive 0.6659 shares of Isabella Bank Corporation common stock and $14.70 per share in cash. Exclusive of the effects of the 10% stock dividend paid February 29, 2008, the Corporation issued 514,809 shares of Isabella Bank Corporation common stock valued at $22,652 and paid a total of $11,365 in cash to GCFC shareholders. The total consideration exchanged including the value of the common stock issued, cash paid to shareholders, plus cash paid for $564 in transaction costs resulted in a total purchase price of $34,581. The purchase price was determined using the latest transaction price known to management as of November 27, 2007, the date of the merger agreement. The acquisition of Greenville has increased the overall market share for Isabella Bank Corporation in furtherance of the Bank’s strategic plan to pursue certain acquisitions.

The following table summarizes the estimate of the total purchase price of the transaction as well as adjustments to allocate the purchase price based on the preliminary estimates of fair values of the assets and liabilities of GCFC.

Core deposit intangible							1,480
Goodwill							21,319
Total consideration paid						$	34,581

The fair value adjustments of tangible net assets acquired are being amortized over two years using the straight line amortization method. The core deposit intangible is being amortized using a 15 year sum-of-the-years’ digits amortization schedule. Goodwill, which is not amortized, is tested for impairment at least annually. As the acquisition was considered a stock transaction, goodwill is not deductible for federal income tax purposes.

The 2008 interim consolidated statements of income include operating results of GCFC since the date of acquisition.

The unaudited pro forma information presented in the following table has been prepared based on Isabella Bank Corporation’s historical results combined with GCFC. The information has been combined to present the results of operations as if the acquisition had occurred at the beginning of the earliest period presented. The pro forma results are not necessarily indicative of the results which would have actually been attained if the acquisition had been consummated in the past or what may be attained in the future (as adjusted for the 10% stock dividend paid February 29, 2008):

Title Joint Venture Formation

On March 1, 2008, IBT Title and Insurance Agency, Inc. (IBT Title), a wholly owned subsidiary of Isabella Bank Corporation, merged its assets and liabilities with Corporate Title Agency, LLC (“Corporate Title”), a third-party title business based in Traverse City, Michigan, to form CT/IBT Title Agency, LLC. As a result of this transaction, the Corporation became a 50 percent joint venture owner in CT/IBT Title Agency, LLC. The purpose of this joint venture was to help IBT Title and Insurance Agency, Inc. expand its service area and to take advantage of economies of scale. As the Corporation is a 50 percent owner of this new entity, revenues and expenses will now be recorded under the equity method, and as such net income from the joint venture will be included in other income. As of June 30, 2008, the Corporation had a recorded investment of $7,094 in the new entity, which is included in equity securities without readily determinable fair values. The following table summarizes the balance sheet of IBT Title as of March 1, 2008. These amounts were excluded from the balance sheet detail of the Corporation and are now included in investment in equity securities without readily determinable fair values.

NOTE 3 — COMPUTATION OF EARNINGS PER SHARE

Basic earnings per share represents income available to common stockholders divided by the weighted–average number of common shares outstanding during the period. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from the assumed issuance. Potential common shares that may be issued by the Corporation relate solely to outstanding shares in the Corporation’s Deferred Director fee plan.

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

	Three Months Ended				Six Months Ended
	June 30				June 30
	2008		2007		2008		2007
Average number of common shares outstanding for basic calculation*		7,483,362		6,968,227		7,498,925		6,970,588
Potential effect of shares in the Deferred Director fee plan*		184,127		196,974		183,489		196,162
Average number of common shares outstanding used to calculate diluted earnings per common share		7,667,489		7,165,201		7,682,414		7,166,750

* As adjusted for the 10% stock dividend paid February 29, 2008

NOTE 4 — OPERATING SEGMENTS

The Corporation’s reportable segments are based on legal entities that account for at least 10 percent of net operating results. In April 2007, the individual bank charters of Isabella Bank and Trust and FSB Bank were consolidated into one bank charter as a part of the Corporation’s strategy to increase efficiencies. As of June 30, 2008 and 2007, retail banking operations represent more than 90 percent of the Corporation’s total assets and operating results. As such, no segment reporting is presented.

NOTE 5 — DEFINED BENEFIT PENSION PLAN

The Corporation has a non-contributory defined benefit pension plan. In December 2006, the Board of Directors voted to curtail the defined benefit plan effective March 1, 2007. The effect of the curtailment, which was recognized in the first quarter of 2007, suspended the current participants’ accrued benefits as of March 1, 2007 and limited participation in the plan to eligible employees as of December 31, 2006. As a result of the curtailment, the Corporation recognized a loss of $37 in the first quarter of 2007 in accordance with SFAS No. 88,Employers’ Accounting for Settlements and Curtailments of Defined Benefit Pension Plans and for Termination Benefits. Due to the curtailment, future salary increases will not be considered and the 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 March 1, 2007. As a result of the curtailment, the Corporation does not anticipate contributing to the plan in the future.

The components of net periodic benefit (income) cost for the three and six month periods ended June 30 are as follows:

	Pension Benefits
	Three months ended						Six Months Ended
	June 30						June 30
	2008			2007			2008			2007

NOTE 6 — FINANCIAL INSTRUMENTS RECORDED AT FAIR VALUE

Fair value is the price that would be expected to be received upon the sale of an asset or transfer of a liability in an orderly transaction between market participants at the measurement date. To increase consistency and comparability in fair value measurements and related disclosures, the fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest level input that is significant to the fair value measurement in its entirety.

Level 1 instruments are those assets for which the identical item is traded on an active exchange, such as publicly-traded instruments. The majority of the fair value amounts included in current period earnings resulted from Level 2 fair value methodologies; that is, the Corporation values the assets and liabilities based on observable market data for similar instruments. The Corporation has no assets or liabilities that meet the Level 3 criteria.

During the first quarter of 2008, the Corporation recorded impairment charges of $30 related to the carrying value of its mortgage servicing rights, in accordance with the provisions of SFAS No. 156, primarily as a result of declines in the rates offered on new residential mortgage loans. This decline in offering rates decreased the expected lives of the loans serviced and in turn decreased the value of the serving rights. However, in the second quarter of 2008, the Corporation reduced the recorded impairment on mortgage servicing rights by $30 as offering rates increased. As such, the net effect of changes in the fair value of the mortgage servicing rights was $0 for the six month period ended June 30, 2008.

During the three month period ended March 31, 2007, in accordance with the provisions of SFAS No. 144, the Corporation recorded an impairment charge of $26 to other real estate owned. The impairment charge was the result of the real estate held declining in value subsequent to the properties being transferred to other real estate.

The activity in the trading portfolio for the three and six month periods ended June 30, 2008 and 2007 was as follows:

	Three Months Ended June 30						Six Months Ended June 30
	2008			2007			2008			2007

The net loss on trading securities, which includes mark-to-market adjustments, totaled $485 and $282 for the three month periods ended June 30, 2008 and 2007, respectively, and $42 and $57 for the six month periods ended June 30, 2008. Of the $42 of losses incurred during the six month period ended June 30, 2008, $8 relates to securities that were held in the Corporation’s trading portfolio as of June 30, 2008.

NOTE 7 — RECENT ACCOUNTING PRONOUNCEMENTS

In May 2008, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 163 (SFAS No.163)Accounting for Financial Guarantee Insurance Contracts-an Interpretation of FASB Statement No.60.The objective of SFAS No. 163 is to clarify how Statement No. 60 applies to financial guarantee insurance contracts, including the recognition and measurement to be used to account for premium revenue and claim liabilities. This statement also requires that an insurance enterprise recognize a claim liability prior to an event of default (insured event) when there is evidence that credit deterioration has occurred in an insured financial obligation. SFAS No. 163 is effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2008 and is not expected to have a significant impact on the Corporation’s consolidated financial statements.

In May 2008, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 162 (SFAS No.162) The Hierarchy of Generally Accepted Accounting Principles.The objective of SFAS No. 162 is to identify the sources of accounting principles and the framework for selecting the principles to be used in the preparation of financial statements of nongovernmental entities that are presented in conformity with generally accepted accounting principles (GAAP) in the United States (the GAAP hierarchy). SFAS No. 162 is effective 60 days following the SEC’s approval of the Public Company Accounting Oversight Board amendments to AU Section 411,The Meaning of Present Fairly in Conformity With Generally Accepted Accounting Principlesand is not expected to have a significant impact on the Corporation’s consolidated financial statements.

On March 19, 2008, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 161 (SFAS No.161)Disclosures about Derivative Instruments and Hedging Activities.The objective of SFAS No. 161 is to enhance disclosures about an entity’s derivative and hedging activities and thereby improve the transparency of financial reporting. SFAS No. 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008 and is not expected to have a significant impact on the Corporation’s consolidated financial statements.

In September of 2006, EITF Issue No. 06-4,Accounting for Deferred Compensation and Postretirement Benefit Aspects of Endorsement Split-Dollar Life Insurance Arrangement, was ratified by the FASB. The EITF reached a consensus that for an endorsement split-dollar life insurance arrangement within the scope of this Issue, an employer should recognize a liability for future benefits. The Corporation has purchased corporation-owned life insurance on certain of its employees. The cash surrender value of these policies is carried as an asset on the condensed consolidated balance sheets. The carrying value was $13,195 at December 31, 2007. These life insurance policies are generally subject to endorsement split-dollar life insurance arrangements. These arrangements were designed to provide a pre-and postretirement benefit for senior officers of the Corporation. The Corporation adopted EITF Issue No. 06-4 effective January 1, 2008 and as a result recorded an initial liability of $2,375. To establish this liability, the Corporation recorded a one time charge of $1,571, net of tax, directly to retained earnings at that date. The periodic policy maintenance costs were $17 and $35 for the three and six month periods ended June 30, 2008, respectively.

Item 2 — Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is management’s discussion and analysis of the major factors that influenced Isabella Bank Corporation’s financial performance. This analysis should be read in conjunction with the Corporation’s 2007 annual report and with the unaudited interim condensed consolidated financial statements and notes, as set forth on pages 3 through 14 of this report.

CRITICAL ACCOUNTING POLICIES:A summary of the Corporation’s significant accounting policies is set forth in Note 1 of the Consolidated Financial Statements included in the Corporation’s Annual Report for the year ended December 31, 2007. Of these significant accounting policies, the Corporation considers its policies regarding the allowance for loan losses and acquisition intangibles to be its most critical accounting policies.

The allowance for loan losses requires management’s most subjective and complex judgment. Changes in economic conditions can have a significant impact on the allowance for loan losses and, therefore, the provision for loan losses and results of operations. The Corporation has developed appropriate policies and procedures for assessing the adequacy of the allowance for loan losses, recognizing that this process requires a number of assumptions and estimates with respect to its loan portfolio. The Corporation’s assessments may be impacted in future periods by changes in economic conditions, and the discovery of information with respect to borrowers which is not known to management at the time of the issuance of the consolidated financial statements. For additional discussion concerning the Corporation’s allowance for loan losses and related matters, see Provision for Loan Losses and Allowance for Loan Losses in the Corporation’s 2007 Annual Report and herein.

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

Net Interest Income

Net interest income equals interest income less interest expense and is the primary source of income for Isabella Bank Corporation. Interest income includes loan fees of $551 and $962 for the three and six month periods ended June 30, 2008, respectively, as compared to $345 and $576 during the same periods in 2007. For analytical purposes, net interest income is adjusted to a “taxable equivalent” basis by adding the income tax savings from interest on tax-exempt loans and securities, thus making year-to-year comparisons more meaningful.

VOLUME AND RATE VARIANCE ANALYSIS

The following table 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 Variance — change in volume multiplied by the previous year’s rate.
     Rate Variance — change in the fully taxable equivalent (FTE) rate multiplied by the prior year’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.

Net interest income as a percentage of earning assets increased 0.31% during the three and six month periods ended June 30, 2008 when compared to the same periods in 2007. The primary reason for this increase was that in early 2007, the Corporation, as part of a balance sheet management strategy, extended the maturities of interest earning assets, which as interest rates declined in the latter half of 2007, had a positive impact on interest margins as the cost of funding sources decreased more rapidly than the rates earned on interest earning assets. Another contributing factor for the increase in margins was a result of the continued shift in the loan portfolio toward higher yielding commercial loans from lower yielding residential mortgage loans.

The total volume and rate variances resulted in net increases in net FTE interest margin of $1,107 related to volume, which was primarily the result of the acquisition of Greenville Community Financial Corporation (See Note 2) and $1,018 related to rates, when the three month period ended June 30, 2008 is compared to the same period in 2007. During the six month period ended June 30, 2008, variances in volume provided $2,296 of additional net FTE interest margin and variances in rates provided $1,830 of additional interest margin when the six month period ended June 30, 2008 is compared to the same period in 2007.

The yield curve began to normalize during the third quarter of 2007, primarily as a result of a 0.50% decrease in the federal funds target rate, resulting in lower short term interest rates. The yield curve further normalized during the fourth quarter of 2007 and during the first six months of 2008 as a result of further rate cuts by the Federal Reserve. In total, the national prime rate has decreased 3.25% since the second quarter of 2007.

The Corporation’s balance sheet is currently well positioned to protect interest margins in a decreasing rate environment, as it is currently liability sensitive. However, management believes the Federal Reserve will, due to inflationary concerns, begin increasing

19

interest rates in the coming year. Given the current liability sensitivity of the Corporation’s balance sheet and the current interest rate environment (which encourages depositors to invest in the short term and loan customers to borrow in the long term), the Corporation’s balance sheet has the potential to continue to be liability sensitive. To help mitigate the potential negative effects of the expected increases in interest rates, management has employed a new balance sheet management strategy, which includes borrowing long term fixed rate Federal Home Loan Bank advances, limiting purchases of investments to short term maturities, and changing the current fed funds purchase position to a sold position. The combination of these actions is expected to decrease current interest margins in the near term, but will provide protection if interest rates do increase in future periods.

Allowance for Loan Losses

The viability of any financial institution is ultimately determined by its management of credit risk. Total loans outstanding represent 64.7% of the Corporation’s total assets and is the Corporation’s single largest concentration of risk. The allowance for loan losses is management’s estimation of potential future losses inherent in the existing loan portfolio. Factors used to evaluate the loan portfolio, and thus to determine the current charge to expense, include recent loan loss history, financial condition of borrowers, amount of nonperforming and impaired loans, overall economic conditions, and other factors. The following table summarizes the Corporation’s charge off and recovery activity for the six month periods ended June 30, 2008 and 2007.

The allowance for loan losses as a percentage of loans has decreased from 1.28% as of June 30, 2007 to 1.15% as of June 30, 2008. The provision for loan losses was increased by $2,450 in 2008. This increase in the provision was the result of the increased level of net loans charged off as well as management’s knowledge of current economic conditions. The Corporation has experienced an increase in foreclosed loans and an increase in loans charged off due mainly to the downturn in the residential real estate mortgage market, which has also resulted in a significant increase in other real estate owned.

The nationwide increase in residential mortgage loans past due and in foreclosures has received considerable attention by both the media and banking regulators. Based on information provided by The Mortgage Bankers Association, the increases in both past dues and foreclosures are related to fixed and adjustable rate sub-prime mortgages. Additionally, a substantial portion of sub-prime adjustable rate mortgages are scheduled to reset at higher rates throughout the remainder of 2008. As a result of the rates resetting on these mortgages, it is expected that troubled sub-prime loans nationally will increase substantially through the end of 2008. While Isabella Bank does not hold sub-prime mortgage loans, the difficulties experienced in the sub-prime market have adversely impacted

20

the entire market, and thus the overall credit quality of the Bank’s residential mortgage portfolio. The increase in troubled residential mortgage loans and a tightening of underwriting standards will most likely result in a continued increase in the inventory of unsold homes. The inventory of unsold homes has not reached these levels since the 1991 recession. The combination of all of these factors is expected to further reduce average home values and thus homeowner’s equity on a national level.

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

Nonperforming loans as a % of total loans		1.30	%		1.20	%
Nonperforming assets as a % of total assets		1.08	%		0.86	%

Due to the aforementioned residential real estate market difficulties being experienced, the Corporation has increased its efforts to identify potential problem loans. Residential real estate loans are placed in nonaccrual status when the foreclosure process has begun, unless there is an abundance of collateral. Additionally, these loans are charged down to their estimated net realizable value when placed on nonaccrual. Historically, residential real estate loans were placed in nonaccrual status upon reaching the beginning of the legally mandated borrower redemption period, which is typically six months. Chargeoffs of any expected deficiency were previously done at the end of the six month redemption period. These increased efforts have had a significant impact on the increase in loans classified as nonaccrual as well as the increase in gross chargeoffs in the first six months of 2008.

The increase in the Corporation’s nonperforming loans is primarily related to the current market difficulties previously discussed. The majority of the increase in other real estate owned is related to two properties, which total $1,170 as of June 30, 2008. Based on management’s analysis of the allowance for loan losses, the current allowance falls within the acceptable range and, therefore, the allowance for loan losses is considered adequate as of June 30, 2008.

Management has devoted considerable attention to identifying loans for which losses are possible adjusting the value of these loans to their current net realizable values. To management’s knowledge, there are no other loans which cause management to have serious doubts as to the ability of a borrower to comply with their loan repayment terms. A continued decline in residential real estate values may require further write downs of loans in foreclosure and other real estate owned and could potentially have an adverse impact on the Corporation’s financial performance.

NONINTEREST INCOME AND EXPENSES

The following discussions of noninterest income and noninterest expenses have been adjusted for the acquisition of Greenville Community Financial Corporation (“GCFC”) on January 1, 2008 to make the line items this quarter more comparable with the corresponding prior period numbers.

Noninterest Income

Noninterest income consists of trust fees, deposit service charges, fees for other financial services, gains on the sale of mortgage loans, and other. Significant account balances are highlighted in the accompanying tables with additional descriptions of significant fluctuations:

As a result of the persistent compression on interest margins, management continuously analyzes various fees related to deposit accounts, including service charges, NSF and overdraft fees, and ATM and debit card fees. Based on these analyses, the Corporation makes any necessary adjustments to ensure that its fee structure is within the range of its competitors, while at the same time making sure that the fees remain fair to deposit customers. Management does not expect significant changes to its deposit fee structure in 2008.

The increases in ATM and debit card fees are primarily the result of the increased usage of debit cards by the Bank’s customers. Management expects ATM and debit card fees to approximate current levels for the remainder of the year.

The decline in net OMSR (originated mortgage servicing rights) income for the first six months of 2008 was the result of increases in amortization expense. This increase in amortization was the result of the estimated lives on the mortgage loans serviced decreasing, which was driven by decreases in the rates offered on new loans in the later part of the first quarter 2008. This temporary decline in rates also helped increase the gain on sale of mortgage loans. However, towards the end of the second quarter of 2008, rates increased which decreased demand for mortgage products and increased the value of servicing portfolio for the quarter ended June 30, 2008.

Title insurance fees have decreased as a result of IBT Title and Insurance Agency’s merger with Corporate Tile on March 1, 2008 (See Note 2 of Notes to Condensed Consolidated Financial Statements).

The large increase in net loss on trading securities during the last three months was primarily related to municipal investment securities. The reason for the large increase in loss in this sector was related to the downgrading of the two largest bond insurers from AAA to AA in June 2008. These downgrades have caused the market to demand higher returns on insured bonds, which has resulted in declines in the value of the Corporation’s municipal bond portfolio, as the majority of the portfolio is insured. Offsetting the losses on trading securities were gains on other borrowings carried at fair market value as there is an inverse relationship between the changes in the value of investments and borrowings. Management does expect trading gains as well as fair value losses on other borrowed funds to stabilize throughout the remainder of 2008.

The first six months of 2008 have been some of the most productive months in the Corporation’s history for brokerage and advisory services. These results are due to an increase in customer base and a conscious effort by management to expand the Bank’s presence in the local market. The Corporation anticipates this trend to continue throughout the rest of the year.

23

Losses on sales of available for sale investment securities were incurred by the Corporation in the first quarter of 2007. This was a result of the Corporation selling investments nearing maturity at low interest rates and reinvesting the proceeds in higher yielding longer term securities as part of asset and liability management. The additional interest income earned upon the reinvestment of the proceeds exceeded the losses recognized in the fourth quarter of 2007.

Leased employee salaries and benefit expenses have decreased as a result of the new joint venture entered into during the first quarter of 2008 (See Note 2). Leased employee benefits have also decreased as a result of the Corporation curtailing its defined benefit pension plan in 2007. Exclusive of the effects of this joint venture, leased employee salaries and benefit expenses have increased due to annual merit increases and the continued growth of the Corporation. Management believes that leased employee salary and benefit expenses will approximate current levels for the remainder of 2008.

Exclusive of the increase in property taxes and ATM and debit card expenses, which was related to increased usage of debit cards by the Bank’s customers, occupancy expenses and furniture and equipment expenses have decreased since 2007. These decreases are a result of IBT Title and Insurance Agency’s merger with Corporate Title, Inc. on March 1, 2008 (See Note 2 of Notes to Condensed Consolidated Financial Statements).

The increase in property taxes is related to the Corporation purchasing two new locations as well as increases in the taxable value of other branch locations due to improvements. Property taxes are anticipated to approximate current levels for the remainder of 2008.

Management has been diligently working to decrease audit and Sarbanes Oxley (SOX) compliance fees. These fees have steadily declined over the past few years as a result of the centralization of corporate processes.

25

Marketing expenses include costs incurred to develop a new brand for the Bank and Corporation, which was publically presented in April 2008. As this process will be ongoing throughout much of 2008, marketing expenses are expected to remain at current levels for the remainder of the year.

The Corporation places a strong emphasis on continuing education for its employees as it is believed that an investment in employees today will pay dividends for years to come. These educational programs help provide team members with a competitive edge in the market place. During the first three months of 2007, the Corporation offered structured leadership training to its employees. This program was designed to help develop and optimize the communication skills of its participants. There were no leadership classes during the first six months of 2008, but management will continue to monitor the need for additional continuing education in the future.

All other expenses include consulting fees, legal fees, title insurance expenses, as well as other miscellaneous expenses, none of which are individually significant, have declined due to management’s diligence in monitoring and controlling expenditures.

The increase in securities available for sale is related to purchases of mortgage backed securities, which are issued by US Government sponsored agencies.

The large increase in equity securities without readily determinable fair values was the result of the merger between IBT Title and Insurance Agency and Corporate Title Agency, LLC (see Note 2 of Notes to Condensed Consolidated Financial Statements). As a result of this transaction, the Corporation is now recording its investment in the new entity as a joint venture under the equity method of accounting. As of June 30, 2008, the Corporation had an investment recorded in the amount of $7,094.

The increase in other borrowed funds was primarily used to help fund common stock repurchases of $6,258 and a $2,500 investment in CT/IBT Title as part of the joint venture agreement. The remainder of these funds were used to purchase investment securities and fund loan growth. Management does anticipate that other borrowed funds will fluctuate based upon its funding needs throughout 2008.

The significant increase in accrued interest and other liabilities is the result of the Corporation’s adoption of EITF 06-4. As a result of the adoption of this pronouncement, the Corporation recorded an initial liability of $2,375 (see Note 7 of Notes to Condensed Consolidated Financial Statements).

The majority of the decrease in premises and equipment and escrow funds payable are a result of the merger of assets and liabilities between IBT Title and Insurance Agency and Corporate Title Agency, LLC (see Note 2 of Notes to Condensed Consolidated Financial Statements), resulting in a reduction in such assets and liabilities.

The decline in shareholders’ equity is primarily related to the Corporation repurchasing and retiring $6,258 of its common stock during the six months of 2008 pursuant to its previously announced repurchase program.

As shown in the above table, management has been successful in increasing the commercial and agricultural loan portfolios and this trend is expected to continue throughout 2008.

Exclusive of the effects of the GCFC merger, residential real estate mortgage loans have declined as a result of the continued soft mortgage market in Michigan. However, the Corporation does anticipate that residential real estate mortgages may increase moderately during the remainder of 2008. Excluding the effects of the GCFC merger, the installment loan portfolio has been steadily decreasing over the past few years as a result of increased competition. Management anticipates the installment loan portfolio to remain stable throughout the remainder of 2008.

As shown in the preceding table total deposits have declined slightly since year end, excluding the effects of the GCFC merger. As a result of these declines, the Corporation has had to rely on additional borrowings to fund its loan growth and other funding needs.

Capital

The capital of the Corporation consists solely of common stock, capital surplus, retained earnings, and accumulated other comprehensive loss. The Corporation offers dividend reinvestment and employee and director stock purchase plans. Under the provisions of these plans, the Corporation issued 50,116 shares or $1,156 of common stock during the first six months of 2008, as compared to 25,241 shares or $990 of common stock as of the same period in 2007. The Corporation also offers share-based payment awards through its equity compensation plan. Pursuant to this plan, the Corporation increased common stock by $286 and $452 during the six month periods ending June 30, 2008 and 2007, respectively.

In October 2002, the Board of Directors authorized management to repurchase up to $2,000 in dollar value of the Corporation’s common stock. In March 2007, the Board of Directors amended this plan which allows for the repurchase of up to 150,000 shares and further amended this plan in May 2008, to allow for the repurchase of an additional 25,000 shares. During the first six months of 2008 and 2007, the Corporation repurchased 143,839 shares of common stock at an average price of $43.51 and 22,734 shares of common stock at an average price of $43.02, respectively.

Accumulated other comprehensive loss increased $1,041 for the six month period ended June 30, 2008, net of tax, and is a result of a unrealized losses on available-for-sale investment securities, of which a substantial portion was related to a significant decline in the value of the Corporation’s municipal bond portfolio. The reason for the large decline in this sector was related to the downgrading of the two largest bond insurers from AAA to AA in June 2008. These downgrades have caused the market to demand higher returns on insured bonds, which has resulted in declines in the value of the Corporation’s municipal bond portfolio, as the majority of the portfolio is insured. Management has reviewed the credit quality of its municipal bond portfolio and believes that there are no losses that are other than temporary.

There are no significant regulatory constraints placed on the Corporation’s capital. The Federal Reserve Board’s current recommended minimum primary capital to assets requirement is 6.0%. The Corporation’s primary capital to adjusted average assets, which consists of shareholders’ equity plus the allowance for loan losses less acquisition intangibles, was 9.49% as of June 30, 2008. There are no commitments for significant capital expenditures.

The Federal Reserve Board has established a minimum risk based capital standard. Under this standard, a framework has been established that assigns risk weights to each category of on and off-balance-sheet items to arrive at risk adjusted total assets. Regulatory capital is divided by the risk adjusted assets with the resulting ratio compared to the minimum standard to determine whether a corporation has adequate capital. The minimum standard is 8%, of which at least 4% must consist of equity capital net of goodwill. The following table sets forth the percentages required under the Risk Based Capital guidelines and the Corporation’s values at June 30, 2008:

29

Percentage of Capital to Risk Adjusted Assets

	Isabella Bank Corporation
	June 30, 2008
	Required			Actual
Equity Capital		4.00	%		12.85	%
Secondary Capital		4.00	%		1.25	%
Total Capital		8.00	%		14.10	%

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

The Federal Reserve and FDIC also prescribe minimum capital requirements for the Corporation’s subsidiary Bank. At June 30, 2008, the Bank exceeded these minimum capital requirements.

Liquidity

The primary sources of the Corporation’s liquidity are cash and demand deposits due from banks, trading securities, and available-for-sale securities. These categories totaled $281,590 or 25.3% of assets as of June 30, 2008 as compared to $263,774 or 27.6% as of December 31, 2007. 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.

Operating activities provided $13,340 of cash in the first six months of 2008, as compared to $41,364 during the same period in 2007. The reduction in cash provided by operating activities, when the first six months of 2008 are compared to 2007, was the result of the Corporation reducing its trading portfolio by $5,609 in 2008 as compared to $36,005 in 2007. Net cash provided by financing activities equaled $37,889 and $5,814 in the six month periods ended June 30, 2008 and 2007, respectively. The Corporation’s investing activities used cash amounting to $49,882 in the first six months of 2008 and $48,695 in the same period in 2007. The accumulated effect of the Corporation’s operating, investing, and financing activities provided $1,347 and used $1,517 in the six months ended June 30, 2008 and 2007, respectively.

Historically, the primary source of funds for the Bank has been deposits. The Bank emphasizes interest-bearing time deposits as part of its funding strategy. The Bank also seeks noninterest bearing deposits, or checking accounts, which reduce the Bank’s cost of funds in an effort to expand the customer base. However, as the competition for borrowings continues to increase, the Corporation has become more dependent on borrowings and other noncore funding sources to fund its growth.

In addition to these primary sources of liquidity, the Corporation has the ability to borrow in the federal funds market and at both the Federal Reserve Bank and the Federal Home Loan Bank, some obligations of which have been reported at fair value to mitigate the Corporation’s interest rate risk. The Corporation’s liquidity is considered adequate by the management of the Corporation. The acquisition of Greenville Community Financial Corporation (see Note 2 of Notes to Condensed Consolidated Financial Statements) did not materially affect the Corporation’s liquidity.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET ARRANGEMENTS

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

The Corporation’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Corporation uses the same credit policies in deciding to make these commitments as it does for extending loans to customers.

Commitments to extend credit, which include unfunded commitments to grant loans and unfunded commitments under lines of credit, totaled $133,733 at June 30, 2008. Commitments generally have variable interest rates, fixed expiration dates, or other termination

30

clauses and may require the payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

Standby letters of credit are conditional commitments issued by the Corporation to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing arrangements, including commercial paper, bond financing, and similar transactions. At June 30, 2008, the Corporation had a total of $5,805 in outstanding standby letters of credit.

Generally, these commitments to extend credit and letters of credit mature within one year. The credit risk involved in these transactions is essentially the same as that involved in extending loans to customers. The Corporation evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Corporation upon the extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, and other income producing commercial properties.

Isabella Bank , a subsidiary of the Corporation, sponsors the IBT Foundation (the “Foundation”), which is a nonprofit entity formed for the purpose of distributing charitable donations to recipient organizations generally located in the communities serviced by Isabella Bank. The Bank periodically makes charitable contributions in the form of cash transfers to the Foundation. The Foundation is administered by members of the Corporation’s Board of Directors. The assets and transactions of the Foundation are not included in the consolidated financial statements of the Corporation. The assets of the Foundation as of June 30, 2008 were $1,004.

Item 3 — Quantitative and Qualitative Disclosures about Market Risk

The Corporation’s primary market risks are interest rate risk and, to a lesser extent, liquidity risk. The Corporation has very limited foreign exchange risk and does not utilize interest rate swaps or derivatives in the management of its interest rate risk. The Corporation does have a significant amount of loans extended to borrowers involved in agricultural production. Cash flow and ability to service debt of such customers is largely dependent on growing conditions and the commodity prices for corn, soybeans, sugar beets, milk, beef and a variety of dry beans. The Corporation mitigates these risks by using conservative price and production yields when calculating a borrower’s available cash flow to service their debt.

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

The Federal Reserve, the Corporation’s primary Federal regulator, has adopted a policy requiring the Board of Directors and senior management to effectively manage the various risks that can have a material impact on the safety and soundness of the Corporation. The risks include credit, interest rate, liquidity, operational, and reputational. The Corporation has policies, procedures and internal controls for measuring and managing these risks. Specifically, the IRR policy and procedures include defining acceptable types and terms of investments and funding sources, liquidity requirements, limits on investments in long term assets, limiting the mismatch in repricing opportunity of assets and liabilities, and the frequency of measuring and reporting to the Board of Directors.

The Corporation uses two main techniques to manage interest rate risk. The first method is gap analysis. Gap analysis measures the cash flows and/or the earliest repricing of the Corporation’s interest bearing assets and liabilities. This analysis is useful for measuring trends in the repricing characteristics of the balance sheet. Significant assumptions are required in this process because of the imbedded repricing options contained in assets and liabilities. A substantial portion of the Corporation’s assets are invested in loans and investment securities. These assets have imbedded options that allow the borrower to repay the balance prior to maturity without penalty. The amount of prepayments is dependent upon many factors, including the interest rate of a given loan in comparison to the current interest rates; for residential mortgages the level of sales of used homes; and the overall availability of credit in the market place. Generally, a decrease in interest rates will result in an increase in the Corporation’s cash flows from these assets. Investment securities, other than those that are callable, do not have any significant imbedded options. Savings and checking deposits may generally be withdrawn on request without prior notice. The timing of cash flow from these deposits is estimated based on historical experience. Time deposits have penalties which discourage early withdrawals. Cash flows may vary based on current offering rates, competition, customer need for deposits, and overall economic activity. As noted above, the Corporation has reclassified a portion of its investment portfolio and its borrowings into trading accounts. Management feels that these practices help it mitigate the volatility of the current interest rate environment.

The second technique used in the management of interest rate risk is to combine the projected cash flows and repricing characteristics generated by the gap analysis and the interest rates associated with those cash flows and projected future interest income. By changing the amount and timing of the cash flows and the repricing interest rates of those cash flows, the Corporation can project the effect of changing interest rates on its interest income.

The following table provides information about the Corporation’s assets and liabilities that are sensitive to changes in interest rates as of June 30, 2008. The Corporation has no interest rate swaps, futures contracts, or other derivative financial options, except for derivative loan commitments, which are not significant. The principal amounts of assets and time deposits maturing were calculated based on the contractual maturity dates. Savings and NOW accounts are based on management’s estimate of their future cash flows.

Item 4 — Controls and Procedures

DISCLOSURE CONTROLS AND PROCEDURES

The Corporation’s management carried out an evaluation, under the supervision and with the participation of the Principal Executive Officer and Principal Financial Officer, of the effectiveness of the design and operation of the Corporation’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15(d)-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) as of June 30, 2008, pursuant to Exchange Act Rule 13a-15. Based upon that evaluation, the Principal Executive Officer and Principal Financial Officer concluded that the Corporation’s disclosure controls and procedures as of June 30, 2008, were effective to ensure that information required to be disclosed by the Corporation in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

During the most recent fiscal quarter, no change occurred in the Corporation’s internal control over financial reporting that materially affected, or is likely to materially effect, the Corporation’s internal control over financial reporting. The Corporation is currently evaluating what changes, if any, might be necessary in internal control arising as a result of the January 1, 2008 acquisition of Greenville Community Financial Corporation.
