ISABELLA BANK CORPORATION
NOTES TO INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
NOTE 1 — BASIS OF PRESENTATION
The accompanying unaudited interim 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 considered necessary for a fair presentation have been included. Operating results for the three month period ended March 31, 2010 are not necessarily indicative of the results that may be expected for the year ending December 31, 2010. 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, 2009.
All amounts except share and per share amounts have been rounded to the nearest thousand ($000) in this report.
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, 2009.
NOTE 2 – RECENT ACCOUNTING PRONOUNCEMENTS
FASB ASC Topic 715, “Compensation – Retirement Benefits.” In January 2010, ASC Topic 715 was amended by Accounting Standards Update (ASU) No. 2010-06, “Improving Disclosures about Fair Value Measurements”, to change the terminology for major categories of assets to classes of assets to correspond with the amendments to ASC Topic 820 (see below). The new guidance was effective for interim and annual periods after January 1, 2010 and had no impact on the Corporation’s consolidated interim financial statements.
FASB ASC Topic 810, “Consolidation.” New authoritative accounting guidance under ASC Topic 810 amends prior guidance to change how a company determines when an entity that is insufficiently capitalized or is not controlled through voting (or similar rights) should be consolidated. The determination of whether a company is required to consolidate an entity is based on, among other factors, an entity’s purpose and design and a company’s ability to direct the activities of the entity that most significantly impact the entity’s economic performance. The new authoritative accounting guidance requires additional disclosures about the reporting entity’s involvement with variable-interest entities and any significant changes in risk exposure due to that involvement as well as its affect on the entity’s financial statements. The new authoritative accounting guidance under ASC Topic 810 was effective January 1, 2010 and had no impact on the Corporation’s consolidated interim financial statements.
FASB ASC Topic 820, “Fair Value Measurements and Disclosures.” In January 2010, ASC Topic 820 was amended by ASU No. 2010-6, to add new disclosures for: (1) Significant transfers in and out of Level 1 and Level 2 fair value measurements and the reasons for the transfers and (2) Presenting separately information about purchases, sales, issuances and settlements for Level 3 fair value instruments (as opposed to reporting activity as net).
ASU No. 2010-6 also clarifies existing disclosures by requiring reporting entities to provide fair value measurement disclosures for each class of assets and liabilities and to provide disclosures about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements.
The new authoritative guidance was effective for interim and annual reporting periods beginning January 1, 2010 except for the disclosures about purchases, sales, issuances and settlements in the rollforward of activity in Level 3 fair value measurements, which will be effective January 1, 2011. The new guidance did not, and is not anticipated to, have a significant impact on the Corporation’s consolidated financial statements.
FASB ASC Topic 860, “Transfers and Servicing.” New authoritative accounting guidance under ASC Topic 860 amends prior accounting guidance to enhance reporting about transfers of financial assets, including securitizations, and where companies have continuing exposure to the risks related to transferred financial assets. The new authoritative accounting guidance eliminates the concept of a “qualifying special-purpose entity” and changes the requirements for derecognizing financial assets. The new authoritative accounting guidance also requires additional disclosures about all continuing involvements with transferred financial

assets including information about gains and losses resulting from transfers during the period. The new authoritative accounting guidance under ASC Topic 860 was effective January 1, 2010 and had no impact on the Corporation’s consolidated interim financial statements.
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, which includes shares held in a Trust controlled by the Corporation. 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:
                 
    Three Months Ended  
    March 31  
    2010     2009  
Average number of common shares outstanding for basic calculation
    7,540,735       7,521,271

The Corporation has invested $11,000 in auction rate money market preferred investment security instruments, which are classified as available-for-sale securities and reflected at estimated fair value. Due to market concentrations and general uncertainty in credit markets, the trading for these securities has been limited. As a result of the limited trading of these securities, $7,800 converted to preferred stock with debt like characteristics in 2009.
Due to the limited trading activity of these securities, the fair values were estimated utilizing a discounted cash flow analysis or other type of valuation adjustment methodology as of March 31, 2010 and December 31, 2009. These analyses consider, among other factors, the collateral underlying the security investments, the creditworthiness of the counterparty, the timing of expected future cash flows and estimates of the next time the security is expected to have a successful auction. As of March 31, 2010, the Corporation had a preferred stock security with a decline in fair market value resulting from the security’s interest rate, as it is significantly lower than the offering rates of securities with similar characteristics. Despite the limited trading of these securities, management has determined that any declines in the fair market value of these securities are the result of interest rates and not the underlying credit quality of the security, it does not intend to sell the securities in an unrealized loss position, and it is more likely than not that the Corporation will not have to sell the securities before recovery of its cost basis.
As of March 31, 2010 and December 31, 2009, management conducted an analysis to determine whether all securities currently in an unrealized loss position, including auction rate money market preferred securities and preferred stocks, should be considered other-than-temporarily-impaired (OTTI). Such analyses considered, among other factors, the following criteria:
    Has the value of the investment declined more than 20% based on a risk and maturity adjusted discount rate?
 
    Is the investment credit rating below investment grade?
 
    Is it probable that the issuer will be unable to pay the amount when due?
 
    Does management assert that it does not intend to sell and will not have to sell the security until recovery of its cost basis?
 
    Has the duration of the investment been extended by more than 7 years?
Based on the Corporation’s analysis using the above criteria, and the fact that management has asserted that it does not have the intent to sell these securities in an unrealized loss position and that it is more likely than not the Corporation will not have sell the securities before recovery of its cost basis, management does not believe that the values of any securities are other-than-temporarily impaired as of March 31, 2010 or December 31, 2009.

NOTE 9 —FAIR VALUE
Financial Instruments Recorded at Fair Value
The Corporation utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities available-for-sale, trading securities, mortgage loans available-for-sale and certain liabilities are recorded at fair value on a recurring basis. Additionally, from time to time, the Corporation may be required to record other assets at fair value on a nonrecurring basis, such as loans held-for-sale, impaired loans, foreclosed assets, originated mortgage servicing rights and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write-downs of individual assets.
Fair Value Hierarchy
Under fair value measurement and disclosure authoritative guidance, the Corporation groups assets and liabilities measured at fair value into three levels, based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine fair value, based on the prioritization of inputs in the valuation techniques. These levels are:
  Level 1:   Valuation is based upon quoted prices for identical instruments traded in active markets.
 
  Level 2:   Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market.
 
  Level 3:   Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability.
The assets or 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 used need to maximize the use of observable inputs and minimize the use of unobservable inputs

As of March 31, 2010 and December 31, 2009, the Corporation had no assets or liabilities measured utilizing Level 1 valuation techniques.
Following is a description of the valuation methodologies and key inputs used to measure financial assets and liabilities recorded at fair value, as well as a description of the methods and significant assumptions used to estimate fair value disclosures for financial instruments not recorded at fair value in their entirety on a recurring basis. For financial assets and liabilities recorded at fair value, the description includes an indication of the level of the fair value hierarchy in which the assets or liabilities are classified
Cash and demand deposits due from banks: The carrying amounts of cash and short-term investments, including Federal funds sold approximate fair values.
Certificates of deposit held in other financial institutions: Interest bearing balances held in 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.
Investment Securities: Investment securities are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss and liquidity assumptions. Level 2 securities include U.S. Treasury securities, mortgage-backed securities issued by government-sponsored entities, municipal bonds and corporate debt securities in active markets. Securities classified as Level 3 include securities in less liquid markets and include auction rate money market preferred securities and preferred stocks.
As discussed above, the Corporation invested $11,000 in auction rate money market preferred investment security instruments, which are classified as available-for-sale securities and reflected at fair value. Due to continuing uncertainty in credit markets, the trading for these investments has been limited, and as such, these investments have been classified as Level 3 since the third quarter of 2008.

Table of Contents

Mortgage Loans Available-for-Sale: Loans available for sale are carried at the lower of cost or market value. The fair value of loans held-for-sale is based on what price secondary markets are currently offering for portfolios with similar characteristics. As such, the Corporation classifies loans subjected to nonrecurring fair value adjustments as Level 2 valuation.
Loans: For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values for other loans (e.g.: real estate mortgage, agricultural, commercial, and installment) are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The resulting amounts are adjusted to estimate the effect of changes in the credit quality of borrowers since the loans were originated.
The Corporation does not record loans at fair value on a recurring basis. However, from time to time, a loan is considered impaired and a specific allowance for loan losses is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as individually impaired, management measures the estimated impairment. The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value, liquidation value and discounted cash flows. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. Impaired loans, where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When a current appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, or the impairment is determined using the net present value of the expected cash flows, the Corporation classifies the impaired loan as nonrecurring Level 3 valuation.
Accrued interest: The carrying amounts of accrued interest approximate fair value.
Acquisition Intangibles and Goodwill: Intangible assets are subject to impairment testing. A projected cash flow valuation method is used in the completion of impairment testing. This valuation method requires a significant degree of management judgment. In the event the projected undiscounted net operating cash flows are less than the carrying value, the asset is recorded at fair value as determined by the valuation model. If the testing resulted in impairment, the Corporation would classify goodwill and other intangible assets subjected to nonrecurring fair value adjustments as Level 3 valuation. During 2010 and 2009, there were no impairments recorded on goodwill and other acquisition intangible assets.
Equity Securities Without Readily Determinable Fair Values: The Corporation has investments in equity securities without readily determinable fair values as well as an investment in a joint venture. The assets are individually reviewed for impairment on an annual basis by comparing the carrying value to the estimated fair value. The lack of an independent source to validate fair value estimates, including the impact of future capital calls and transfer restrictions, is an inherent limitation in the valuation process. The Corporation classifies nonmarketable equity securities and its investment in a joint venture subjected to nonrecurring fair value adjustments as Level 3 valuation. During 2010 and 2009, there were no impairments recorded on equity securities without readily determinable fair values.
Foreclosed Assets: Upon transfer from the loan portfolio, foreclosed assets are adjusted to and subsequently carried at the lower of carrying value or fair value less estimated costs to sell. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral and as such, the Corporation classifies foreclosed assets as nonrecurring Level 2 valuation. When a current appraisal is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the Corporation records the foreclosed asset as nonrecurring Level 3 valuation.
Originated Mortgage Servicing Rights: Loan servicing rights are subject to impairment testing. A valuation model, which utilizes a discounted cash flow analysis using interest rates and prepayment speed assumptions currently quoted for comparable instruments and a discount rate determined by management, is used for impairment testing. If the valuation model reflects a value less than the carrying value, mortgage servicing rights are adjusted to fair value through a valuation allowance as determined by the model. As such, the Corporation classifies loan servicing rights subjected to nonrecurring fair value adjustments as Level 2 valuation.
Deposits: Demand, savings, and money market deposits are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for variable rate certificates of deposit approximate their recorded carrying value. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Table of Contents

Borrowed Funds: The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings maturing within ninety days approximate their fair values. The fair values of the Corporation’s other borrowings are estimated using discounted cash flow analyses based on the Corporation’s current incremental borrowing arrangements.
The Corporation has elected to measure a portion of other borrowed funds at their fair value. These borrowings are recorded at fair value on a recurring basis, with the fair value measurement estimated using discounted cash flow analysis based on the Corporation’s current incremental borrowings rates for similar types of borrowing arrangements. Changes in the fair value of these borrowings are included in noninterest income. As such, the Corporation classifies other borrowed funds as Level 2 valuation.
Commitments to extend credit, standby letters of credit and undisbursed loans: Fair values for off-balance-sheet lending commitments are based on fees currently charged to enter into similar agreements, taking into consideration the remaining terms of the agreements and the counterparties’ credit standings. The Corporation does not charge fees for lending commitments; thus it is not practicable to estimate the fair value of these instruments.
The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Estimated Fair Values of Financial Instruments Not Recorded at Fair Value in their Entirety on a Recurring Basis
Disclosure of the estimated fair values of financial instruments, which differ from carrying values, often requires the use of estimates. In cases where quoted market values in an active market are not available, the Company uses present value techniques and other valuation methods to estimate the fair values of its financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used.
The carrying amount and estimated fair value of financial instruments not recorded at fair value in their entirety on a recurring basis on the Corporation’s consolidated balance sheets are as follows:

NOTE 10 — OPERATING SEGMENTS
The Corporation’s reportable segments are based on legal entities that account for at least 10 percent of net operating results. As of March 31, 2010 and 2009 and each of the three month periods then ended, the operations of Isabella Bank (the “Bank”) represented 90% or more of the Corporation’s total assets and operating results. Therefore, the Corporation has only one operating segment and no segment reporting is required.

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 2009 annual report and with the unaudited interim condensed consolidated financial statements and notes, beginning on page 3 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, 2009. Of these significant accounting policies, the Corporation considers its policies regarding the allowance for loan losses, acquisition intangibles (including goodwill), and the determination of the fair value of investment securities 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 appropriateness 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 the Corporation’s 2009 Annual Report and the following discussion herein.
Accounting principles generally accepted in the United States of America require that the Corporation determine the fair value of the assets and liabilities of an acquired entity, and record their fair value on the date of acquisition. The Corporation employs a variety of measures in the determination of the fair value, including the use of discounted cash flow analysis, market appraisals, and projected future revenue streams. For certain items that management believes it has the appropriate expertise to determine the fair value, management may choose to use its own calculations of the value. In other cases, where the value is not easily determined, the Corporation consults with outside parties to determine the fair value of the identified asset or liability. Once valuations have been adjusted, the net difference between the price paid for the acquired entity and the value of its balance sheet, including identifiable intangibles, is recorded as goodwill. This goodwill is not amortized, but is tested for impairment on at least an annual basis.
The Corporation currently has both available-for-sale and trading investment securities that are carried at fair value. Changes in the fair value of available-for-sale investment securities are included as a component of other comprehensive income, while declines in the fair value of these securities below their cost that are other than temporary would be reflected as realized losses. The change in value of trading investment securities is included in current earnings. Management evaluates securities for indications of losses that are considered other-than-temporary, if any, on a regular basis. The market values for available-for-sale and trading investment securities are typically obtained from outside sources and applied to individual securities within the portfolio. The fair values of investment securities with illiquid markets are estimated by management utilizing a discounted cash flow analysis or other type of valuation adjustment methodology. These securities are also compared, when possible, to other securities with similar characteristics.

Isabella Bank Corporation, as well as all other financial institutions in Michigan and across the entire country, has felt the negative impacts of the current economic recession. This recession, which began in 2008, has resulted in historically high levels of loan delinquencies and nonaccrual loans, which have translated into increases in net loans charged off and foreclosed asset and collection expenses. Despite the current economic downturn, the Corporation continues to be profitable, with net income of $2,023 for the three month period ended March 31, 2010. The Corporation’s nonperforming loans represented 1.21% of total loans as of March 31, 2010 which declined from 1.28% as of December 31, 2009. The ratio of nonperforming loans to total loans for all banks in the state of Michigan was 4.43% as of December 31, 2009 (March 31, 2010 state of Michigan ratios are not yet available). The Corporation’s interest margins also continue to be strong, as the net yield on interest earning assets (on a fully tax equivalent basis) improved to 4.04% for the three months ended March 31, 2010 compared to 3.97% for the same period in 2009. For further detailed discussion and analysis, see below.
Net Interest Income
Net interest income equals interest income less interest expense and is the primary source of income for the Corporation. Interest income includes loan fees of $403 for the three month period March 31, 2010, as compared to $450 during the same period in 2009. 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.

The Corporation’s net yield on interest earning assets increased by 0.07% when the first 3 months of 2010 are compared to the same period in 2009. The main factor contributing to the increase is that interest rates paid on interest bearing liabilities have declined faster than those earned on interest earning assets. When the three month period ended March 31, 2010 is compared to the three month period ended December 31, 2009, the net yield on interest earning assets has declined by 0.05%.
Despite an increase in interest earning assets of $8,268 from March 31, 2009 to March 31, 2010, overall interest income decreased as a result of a change in the mix of interest earning assets. The decline in loans was offset with an increase in investment securities as well as other interest earning assets, which have a lower average yield than loans.
The Corporation anticipates that net interest margin yield will decline during 2010 due to the followings factors:
    Based on the current economic conditions, management does not anticipate any changes in the target Fed Funds rate until at least the fourth quarter of 2010. As such, the Corporation does not anticipate significant, if any, changes in market rates. However, there is the potential for declines in rates earned on interest earning assets. Most of the potential declines would arise out of the Corporation’s investment portfolio, as securities, which are either called or matured during 2010, will likely be reinvested at lower rates.

    While long term residential mortgage rates have increased during the first three months of 2010, they are still at historically low levels. This rate environment has led to strong consumer demand for fixed rate mortgage products which are generally sold to the secondary market. As a result, there has been a significant decline in three and five year balloon mortgages, which are held on the Corporation’s balance sheet. As these balloon mortgages have paid off, the proceeds from these loans have been reinvested (typically in the form of available-for-sale investment securities) at lower interest rates which has adversely impacted interest income.
    While the Corporation’s liability sensitive balance sheet has allowed it to benefit from decreases in interest rates, it also makes the Corporation extremely sensitive to increases in deposit and borrowing rates. As part of the Corporation’s goal to minimize the potential negative impacts of possible increases in future interest rates, management is actively working to lengthen the terms of its interest bearing liabilities. This lengthening has increased the Corporation’s cost of funding, reducing net interest income in the short term.
    In an effort to reduce the potential long term negative impact of increases in rates paid on interest bearing liabilities, the Corporation will continue to grow its balance sheet through the acquisition of investment securities. These investments will be funded through deposit growth and wholesale borrowings. The net interest margin generated by the purchase of these investments is anticipated to be less than 2.0%, lowering the net FTE yield, but providing additional net interest income.
Allowance for Loan Losses
The viability of any financial institution is ultimately determined by its management of credit risk. Loans outstanding represent the Corporation’s single largest concentration of risk. The allowance for loan losses is management’s estimation of potential 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 three month periods ended March 31:

In the past two years, residential real estate values in the Corporation’s market areas have declined 20% to 40%. These declines are the result of increases in the inventory of unsold homes. This increased inventory is partially the result of the inability of potential home buyers to obtain financing due to the tightening of loan underwriting criteria by many financial institutions, brokers and government sponsored agencies. While the Corporation has maintained traditional lending standards, the decline in real estate values has had an adverse impact on customers who are experiencing financial difficulties. Historically, customers who experienced

Table of Contents

difficulties were able to sell their properties for more than the loan balance owed. The steep decline in real estate values has diminished homeowner equity and led borrowers who are experiencing financial difficulties to default on their mortgage loans.
The Corporation originates and sells fixed rate residential real estate mortgages to the Federal Home Loan Mortgage Corporation (Freddie Mac). The Corporation has not originated loans for either trading or its own portfolio that would be classified as subprime, nor has it originated adjustable rate mortgages or financed loans for more than 80% of market value unless insured by private third party insurance.
While the Corporation has elected not to participate in the U.S. Treasury’s “Making Home Affordable Program”, it has taken aggressive actions to avoid foreclosures on borrowers who are willing to work with the Corporation in modifying their loans, thus making them more affordable. Actions taken include extensions of amortizations, temporary reductions in interest rates and, when necessary, a reduction in the principal balance owed.
As shown in the preceding table, when comparing the first three months of 2010 to the same period in 2009, net loans charged off decreased by $330. This improvement allowed the Corporation to reduce its provision for loan losses in the first quarter 2010 by $337 when compared to the fourth quarter of 2009. While there have been marked improvements in the level of net loans charged off and nonperforming assets, which has contributed to the Corporation’s ability to reduce its provision for loan losses, the overall local, regional and national economies have yet to show consistent improvement.
Based on management’s analysis, the allowance for loan losses of $12,987 is considered appropriate as of March 31, 2010. Management will continue to closely monitor its overall credit quality during 2010 to ensure that the allowance for loan losses remains appropriate.

Loans are placed in nonaccrual status when the foreclosure process has begun, generally after a loan is 90 days past due, unless there is an abundance of collateral. Upon transferring the loans to nonaccrual status, an evaluation to determine the net realizable value of the underlying collateral is performed. This evaluation is used to help determine if any charge downs are necessary.
Since December 31, 2009, the Corporation’s nonperforming loans have declined while restructured loans have increased. The majority of the increase in restructured loans is the result of the Corporation working with borrowers to develop a payment structure that will allow them to continue making payments in lieu of foreclosure.
Management has devoted considerable attention to identifying loans for which inherent losses are probable and 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.

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.
As of March 31, 2010, there were no other interest bearing assets which required classification. Management is not aware of any recommendations by regulatory agencies that, if implemented, would have a material impact on the Corporation’s liquidity, capital, or operations.
NONINTEREST INCOME AND EXPENSES
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:

Significant changes in noninterest income are detailed below:
    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. NSF and overdraft fees have been declining over the past two years. This decline is a result of customers more closely managing their deposit accounts to avoid paying overdraft fees. The Corporation anticipates that NSF and overdraft fees will decline in the third quarter of 2010 as a result of new legislation that will be implemented related to NSF and overdraft fees. Management is in the process of reviewing other deposit fees.
 
    The increases in ATM and debit card fees are primarily the result of the increased usage of debit cards by customers. As management does not anticipate any significant changes to the ATM and debit card fee structures, these fees are expected to continue to increase as the usage of debit cards increases.

    As a result of lower than normal residential mortgage rates, the Corporation has experienced increases in the volume of loans sold to Freddie Mac since the fourth quarter of 2008. This high volume led to increases in gains from the sale of mortgage loans in the first quarter of 2009. The volume of new mortgage activity has returned to more normal levels, leading to a decline in the gain on sale of mortgage loans compared to the same period in 2009. The Corporation is now seeing increases in Freddie Mac servicing fees and net originated mortgage servicing rights (OMSR) as the pool of serviced loans has increased by $42,136 since March 31, 2009. As refinancing activity is expected to decline, the Corporation anticipates net OMSR income to decline throughout the remainder of the year. The Corporation anticipates that Freddie Mac servicing fees and gains from the sale of mortgage loans will approximate current levels for the remainder of 2010.
 
    Fluctuations in the gains and losses related to trading securities and borrowings carried at fair market value are caused by interest rate variances. Management does not anticipate any significant fluctuations in net trading activities for the remainder of the year as significant interest rate changes are not expected.
 
    The Corporation is continuously analyzing its available-for-sale investment portfolio to take advantage of selling opportunities that would generate gains. Currently, management does not anticipate any significant sales throughout the remainder of 2010.
 
    Fees generated from brokerage and advisory services have been steadily increasing for the past few years. This has been the result of staff additions as well as a conscious effort by management to expand the Corporation’s presence in its local market. Management anticipates this trend to continue throughout 2010.
 
    The fluctuations in all other income are spread throughout various categories, none of which are individually significant.

Significant changes in noninterest expenses are detailed below:
    Salaries and hourly wages increased slightly due to annual merit increases and the continued growth of the Corporation.
 
    Leased employee benefits declined primarily as a result of decreases in the Corporation’s health care claims.
 
    FDIC insurance premium expense has decreased primarily as a result of an FDIC special assessment of $479, which was paid in September 2009, but was fully accrued as of March 31, 2009.
 
    Audit and SOX compliance fees increased in the first three months of 2010, when compared to the same period in 2009, as more of the 2009 year-end audit procedures and reviews were performed subsequent to December 31, 2009.
 
    Marketing and community relations expenses have primarily increased as a result of the Corporation increasing its charitable contributions during the first quarter of 2010. Management anticipates that marketing and community relations expenses will decline slightly over the remainder of 2010.
 
    Printing and supplies expenses were historically high in the first three months of 2009 as a result of the Corporation increasing inventories of various supplies. Printing and supplies expenses are expected to approximate current levels for the remainder of 2010.
 
    The Corporation places a strong emphasis on customer service. In February 2010, all of the Corporation’s employees attended a special customer service seminar, which contributed to the increase in education and travel expenses. These expenses are expected to decline slightly throughout the remainder of 2010.
 
    Postage and freight expenses have declined as a result of fewer special mailings as well as an increase in the Corporation’s customers usage of electronic statements.
 
    While legal expenses have declined in comparison to 2009, legal and foreclosed asset and collection expenses continue to be at historically high levels. Management anticipates that these expenses will approximate current levels throughout the remainder of 2010.
 
    The fluctuations in all other expenses are spread throughout various categories, none of which are individually significant.

As shown in the preceding table the growth in deposits since December 31, 2009 came primarily in the form of savings deposits, which includes increases in money market accounts as well as other savings accounts. Total deposit accounts are expected to increase slightly over the remainder of 2010, with much of the growth coming in the form of certificates of deposits as the Corporation’s intent is to lengthen the repricing of its interest bearing liabilities.
Capital
The capital of the Corporation consists solely of common stock, 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 29,147 shares or $736 of common stock during the first three months of 2010, as compared to 20,977 shares or $478 of common stock during the same period in 2009. The Corporation also offers share-based payment awards through its equity compensation plan. Pursuant to this plan, the Corporation increased common stock by $181 and $184 during the three month periods ended March 31, 2010 and 2009, respectively.
The Board of Directors has approved a common stock repurchase plan to enable the Corporation to repurchase its common stock for reissuance to the dividend reinvestment plan, the employee stock purchase plan and for distributions of share-based payment awards. During the first three months of 2010 and 2009, pursuant to this plan, the Corporation repurchased 34,165 shares of common stock at an average price of $18.41 and 24,428 shares of common stock at an average price of $23.25, respectively. As of March 31, 2010, the Corporation was authorized to repurchase up to an additional 44,267 shares of common stock.
Accumulated other comprehensive loss decreased $815 for the three month period ended March 31, 2009, net of tax. The decrease is a result of unrealized gains on available-for-sale investment securities. Management has reviewed the credit quality of its 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 8.52% as of March 31, 2010.
There are no commitments for significant capital expenditures for the remainder of 2010.

Table of Contents

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:
                         
    March 31     December 31        
    2010     2009     Required  
Equity Capital
    12.22 %     12.80 %     4.00 %
Secondary Capital
    1.25 %     1.25 %     4.00 %
 
                 
Total Capital
    13.47 %     14.05 %     8.00 %
 
                 
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 Bank. At March 31, 2010, the Bank exceeded these minimum capital requirements. There is currently proposed legislation to increase the level of capital for banks. This increase in capital levels may have an adverse impact on the Corporation’s ability to grow and pay dividends.
Liquidity
The primary sources of the Corporation’s liquidity are cash and demand deposits due from banks, certificates of deposit held in other financial institutions, trading securities, and available-for-sale securities, excluding money market preferred securities and preferred stocks due to their illiquidity as of March 31, 2010 and December 31, 2009. These categories totaled $302,429 or 26.2% of assets as of March 31, 2010 as compared to $292,464 or 25.6% as of December 31, 2009. 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. On a daily basis, liquidity varies significantly, based on customer activity.
Historically, the primary source of funds for the Corporation has been deposits. The Corporation emphasizes interest-bearing time deposits as part of its funding strategy. The Corporation also seeks noninterest bearing deposits, or checking accounts, which reduce the Corporation’s cost of funds in an effort to expand the customer base. However, as the competition for core deposits 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 at the Federal Reserve Bank, the Federal Home Loan Bank, as well as other correspondent banks. The Corporation’s liquidity is considered adequate by the management of the Corporation.
The following table summarizes the Corporation’s sources and uses of cash for the three month periods ended March 31:

Net cash provided by operating activities increased due to:
    An increase in the volume of maturities, calls and sales of trading securities.
 
    A net decrease in the level of loans held for sale in the first three months of 2010 as compared to an increase in the same period in 2009.
Investing activities used cash in 2010 as compared to providing cash in 2009 due to:
    A reduction in the volume of maturities, calls and sales of available-for-sale securities.
 
    A net increase in loans in 2010 as compared to a decrease in 2009.
Financing activities provided cash in 2010 as compared to using cash in 2009 due to:
    Deposit account balances increasing more in 2010 than in 2009.
 
    The Corporation reducing its borrowed funds less in 2010 than in 2009.
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 $125,201 and $121,356 as of March 31, 2010 and December 31, 2009, respectively. Commitments generally have variable interest rates, fixed expiration dates, or other termination 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. The Corporation had a total of $4,441 and $6,509 in outstanding standby letters of credit as of March 31, 2010 and December 31, 2009, respectively.
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.

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. The Corporation has reclassified a portion of its investment portfolio and its borrowings into trading accounts. Management believes 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 March 31, 2010 and December 31, 2009. 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.
