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

NOTES TO INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
(Dollars in thousands except per share amounts)
Note 1 – Basis of Presentation
As used in these notes, as well as in Management's Discussion and Analysis of Financial Condition and Results of Operations, references to “Isabella,” the “Corporation,” “we,” “our,” “us,” and similar terms refer to the consolidated entity consisting of Isabella Bank Corporation and its subsidiaries. Isabella Bank Corporation refers solely to the parent holding company, and Isabella Bank or the “Bank” refers to Isabella Bank Corporation’s subsidiary, Isabella Bank.
The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with GAAP 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 GAAP for complete financial statements. In our opinion, all adjustments considered necessary for a fair presentation have been included. Operating results for the three month period ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. For further information, refer to our Annual Report on Form 10-K for the year ended December 31, 2017.
Our accounting policies are materially the same as those discussed in Note 1 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2017.
Reclassifications: Certain amounts reported in the interim 2017 consolidated financial statements have been reclassified to conform with the 2018 presentation.
Note 2 – Computation of Earnings Per Common Share
Basic earnings per common share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per common share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued. Potential common shares that may be issued relate solely to outstanding shares in the Directors Plan.

Note 3 – Accounting Standards Updates
Recently Adopted Accounting Standards Updates
ASU No. 2014-09: “Revenue from Contracts with Customers”
In May 2014, ASU No. 2014-09 created new Topic 606 to provide a common revenue standard to achieve consistency and clarification to the revenue recognition principles. The guidance outlines steps to achieve the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. These steps consist of: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation.
The new authoritative guidance, as amended, was effective on January 1, 2018. We reviewed our contracts related to trust and investment services and those related to other noninterest income to determine if changes in income recognition were required

as a result of this guidance. Implementation of this guidance did not have a significant impact on our operating results for the three month period ended March 31, 2018.
ASU No. 2016-01: “Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities”
In January 2016, ASU No. 2016-01 set forth the following: 1) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income; 2) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment and requiring measurement of the investment at fair value when an impairment exists; 3) for public entities, eliminates the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; 4) for public entities, requires the use of exit price notion when measuring the fair value of financial instruments for disclosure purposes; 5) requires an entity to present separately in other comprehensive income, the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; 6) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; and 7) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity's other deferred tax assets.
The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2017. As a result of this guidance, the change in the fair value of equity investments has been recorded in net income beginning on January 1, 2018. Equity securities are now recorded separately from AFS securities and are recorded at a fair value which approximates an exit price notion. Adoption of this guidance had an insignificant impact on our operations and its future impact will depend on the fair value of these investments at the future measurement dates. The disclosures related to equity investment securities reflect a fully retrospective presentation for comparative purposes.
For discussion of the fair value measurement of financial instruments, refer to “Note 11 – Fair Value”.
In February 2018, ASU No. 2018-03: “Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10: Recognition and Measurement of Financial Assets and Financial Liabilities” was issued. This update sets forth correction or improvement amendments for specific issues that may arise within the scope of ASU 2016-01. These amendments follow ASU 2016-01 with regard to effective dates.
ASU No. 2017-09: “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting”
In May 2017, ASU No. 2017-09 was issued and provided guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718. The current disclosure requirements in Topic 718 apply regardless of whether an entity is required to apply modification accounting under the amendments in this update. An entity should account for the effects of a modification unless all of the following are met:
1. The fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification.
2. The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified.
3. The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified.
The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2017 and did not have a significant impact on our operating results or financial statement disclosures.
Pending Accounting Standards Updates
ASU No. 2016-02: “Leases (Topic 842)”
In February 2016, ASU No. 2016-02 was issued to create Topic 842 - Leases which will require recognition of lease assets and lease liabilities on the balance sheet for leases previously classified as operating leases. Accounting guidance is set forth for
11

Table of Contents
both lessee and lessor accounting. Under lessee accounting, a lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term.
For finance leases, a lessee is required to do the following: 1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position; 2) recognize interest on the lease liability separately from amortization of the right-of-use asset in the statement of comprehensive income; and 3) classify repayments of the principal portion of the lease liability within financing activities and payments of interest on the lease liability and variable lease payments within operating activities in the statement of cash flows. For operating leases, a lessee is required to do the following: 1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position; 2) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis; and 3) classify all cash payments within operating activities in the statement of cash flows.
The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2018. We have and will continue to review our lease agreements to determine the appropriate treatment under this guidance. We do not expect these changes to have a significant impact on our operating results or financial statement disclosures.
ASU No. 2016-13: “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”
In June 2016, ASU No. 2016-13 updated the measurement for credit losses for AFS debt securities and assets measured at amortized cost which include loans, trade receivables, and any other financial assets with the contractual right to receive cash. Current GAAP requires an “incurred loss” methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. Under the incurred loss approach, entities are limited to a probable initial recognition threshold when credit losses are measured under GAAP; an entity generally only considers past events and current conditions in measuring the incurred loss.
Under the new guidance, the incurred loss impairment methodology in current GAAP is replaced with a methodology that reflects current expected credit losses (CECL). This methodology requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances which applies to assets measured either collectively or individually.
The update allows an entity to revert to historical loss information that is reflective of the contractual term (considering the effect of prepayments) for periods that are beyond the time frame for which the entity is able to develop reasonable and supportable forecasts. In addition, the disclosures of credit quality indicators in relation to the amortized cost of financing receivables, a current disclosure requirement, are further disaggregated by year of origination (or vintage). The vintage information will be useful for financial statement users to better assess changes in underwriting standards and credit quality trends in asset portfolios over time and the effect of those changes on credit losses.
Overall, the update will allow entities the ability to measure expected credit losses without the restriction of incurred or probable losses that exist under current GAAP. For users of the financial statements, the update provides decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The new authoritative guidance is effective for interim and annual periods beginning after December 15, 2019 and may have a significant impact on our operations and financial statement disclosures as well as that of the banking industry as a whole.
We have invested a considerable amount of effort toward this guidance and will continue to invest considerable effort until its effective date. A committee was formed and has developed a road map to implementation. This committee will monitor progress to ensure timely and accurate adoption of the guidance. We are working to identify and collect required borrower and loan level data. We recognize that quality data is key to properly identify loan segments and then apply the most appropriate methodology to each segment. We anticipate a significant amount of progress during 2018 to position ourselves to be able to run parallel models during 2019. This will allow us to solidify our methodology for implementation in 2020.

Expected maturities for government sponsored enterprises and states and political subdivisions may differ from contractual maturities because issuers may have the right to call or prepay obligations.
As the auction rate money market preferred stocks have continual call dates, they are not reported by a specific maturity group. Because of their variable monthly payments, mortgage-backed securities and collateralized mortgage obligations are not reported by a specific maturity group.

As of March 31, 2018 and December 31, 2017, we conducted an analysis to determine whether any AFS securities currently in an unrealized loss position should be other-than-temporarily impaired. Such analyses considered, among other factors, the following criteria:

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

• | Is the investment credit rating below investment grade?

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

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

• | Has the duration of the investment been extended?

During the fourth quarter of 2016, we identified one municipal bond as other-than-temporarily impaired. While management estimated the OTTI to be realized, we also engaged the services of an independent investment valuation firm to estimate the amount of impairment as of December 31, 2016. The valuation calculated the estimated market value utilizing two different approaches:
1) Market - Appraisal and Comparable Investments
2) Income - Discounted Cash Flow Method
The two methods were then weighted, with a higher weighting applied to the Market approach, to determine the estimated impairment. As a result of this analysis, we reduced the carrying value to $230 which required us to recognized an OTTI of $770 in earnings for the year ended December 31, 2016. Based on internal analysis of this bond as of March 31, 2018, there was no additional OTTI recognized as of March 31, 2018 and the carrying value of this bond remained at $230.

The following table provides a roll-forward of credit related impairment recorded in earnings for the:

| Three Months Ended March 31

Balance at beginning of the period | $ | 770 |  |  | $ | 770 |
Additions to credit losses for which no previous OTTI was recognized | — |  |  | — |
Reductions for credit losses realized on securities sold during the period | — |  |  | — |
Balance at end of the period | $ | 770 |  |  | $ | 770 |

Based on our analysis which included the criteria outlined above, the fact that we have asserted that we do not have the intent to sell AFS securities in an unrealized loss position, and considering it is unlikely that we will have to sell any AFS securities in an unrealized loss position before recovery of their cost basis, we do not believe that the values of any other AFS securities are other-than-temporarily impaired as of March 31, 2018 or December 31, 2017, with the exception of the one municipal bond discussed above.
Note 5 – Loans and ALLL
We grant commercial, agricultural, residential real estate, and consumer loans to customers situated primarily in Clare, Gratiot, Isabella, Mecosta, Midland, Montcalm, and Saginaw counties in Michigan. The ability of the borrowers to honor their repayment obligations is often dependent upon the real estate, agricultural, manufacturing, retail, gaming, tourism, higher education, and general economic conditions of this region. Substantially all of our consumer and residential real estate loans are secured by various items of property, while commercial loans are secured primarily by real estate, business assets, and personal guarantees. Some loans are unsecured.
Loans that we have the intent and ability to hold in our portfolio are reported at their outstanding principal balance adjusted for any charge-offs, the ALLL, and any deferred fees or costs. Interest income is accrued over the term of the loan based on the principal amount outstanding. Loan origination fees and certain direct loan origination costs are capitalized and recognized as a component of interest income over the term of the loan using the level yield method.
The accrual of interest on commercial, agricultural, and residential real estate loans is discontinued at the time the loan is 90 days or more past due unless the credit is well-secured and in the process of collection. Upon transferring the loans to nonaccrual status, we perform an evaluation to determine the net realizable value of the underlying collateral. This evaluation is used to help determine if any charge-offs are necessary. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful.
For loans that are placed on nonaccrual status or charged-off, all interest accrued in the current calendar year, but not collected, is reversed against interest income while interest accrued in prior calendar years, but not collected, is charged against the ALLL. Loans may be returned to accrual status after six months of continuous performance and achievement of current payment status.
Commercial and agricultural loans include loans for commercial real estate, commercial operating loans, advances to mortgage brokers, farmland and agricultural production, and states and political subdivisions. Repayment of these loans is dependent upon the successful operation and management of a business. We minimize our risk by limiting the amount of direct credit exposure to any one borrower to $15,000. Borrowers with direct credit needs of more than $15,000 are serviced through the use of loan participations with other commercial banks. Commercial and agricultural real estate loans commonly require loan-to-value limits of 80% or less. Depending upon the type of loan, past credit history, and current operating results, we may require the borrower to pledge accounts receivable, inventory, and property and equipment. Personal guarantees are generally required from the owners of closely held corporations, partnerships, and sole proprietorships. In addition, we require annual financial statements, prepare cash flow analyses, and review credit reports.
We entered into a mortgage purchase program in 2016 with a financial institution where we participate in advances to mortgage brokers ("advances"). The mortgage brokers originate residential mortgage loans with the intent to sell them on the secondary market. We participate in the advance to the mortgage broker, which is secured by the underlying mortgage loan, until it is ultimately sold on the secondary market. As such, the average life of each participated advance is approximately 20-30 days. Funds from the sale of the loan are used to pay off our participation in the advance to the mortgage broker. We classify these advances as commercial loans and include the outstanding balance in commercial loans on our balance sheet. Under the participation agreement, we committed to a maximum outstanding aggregate amount of $30,000. The difference between our outstanding balances and the maximum outstanding aggregate amount is classified as “Unfunded commitments under lines of

credit” in the “Contractual Obligations and Loan Commitments” section of the Management's Discussion and Analysis of Financial Condition and Results of Operations of this report.
We offer adjustable rate mortgages, construction loans, and fixed rate residential real estate loans which have amortization periods up to a maximum of 30 years. We consider the anticipated direction of interest rates, balance sheet duration, the sensitivity of our balance sheet to changes in interest rates, and overall loan demand to determine whether or not to sell fixed rate loans to Freddie Mac.
Our lending policies generally limit the maximum loan-to-value ratio on residential real estate loans to 100% of the lower of the appraised value of the property or the purchase price. Private mortgage insurance is typically required on loans with loan-to-value ratios in excess of 80% unless the loan qualifies for government guarantees.
Underwriting criteria for originated residential real estate loans generally include:

• | Evaluation of the borrower’s ability to make monthly payments.

• | Evaluation of the value of the property securing the loan.

• | Ensuring the payment of principal, interest, taxes, and hazard insurance does not exceed 28% of a borrower’s gross income.

• | Ensuring all debt servicing does not exceed 40% of income.

• | Verification of acceptable credit reports.

• | Verification of employment, income, and financial information.

Appraisals are performed by independent appraisers and reviewed for appropriateness. All mortgage loan requests are reviewed by our mortgage loan committee or through a secondary market underwriting system; loans in excess of $500 require the approval of our Internal Loan Committee, the Executive Loan Committee, the Board of Directors’ Loan Committee, or the Board of Directors.
Consumer loans include secured and unsecured personal loans. Loans are amortized for a period of up to 15 years based on the age and value of the underlying collateral. The underwriting emphasis is on a borrower’s perceived intent and ability to pay rather than collateral value. No consumer loans are sold to the secondary market.
The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the ALLL when we believe the uncollectability of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the ALLL.
The appropriateness of the ALLL is evaluated on a quarterly basis and is based upon a periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.
The primary factors behind the determination of the level of the ALLL are specific allocations for impaired loans, historical loss percentages, as well as unallocated components. Specific allocations for impaired loans are primarily determined based on the difference between the loan’s outstanding balance and the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral, less cost to sell. Historical loss allocations are calculated at the loan class and segment levels based on a migration analysis of the loan portfolio, with the exception of advances to mortgage brokers, over the preceding five years. With no historical losses on advances to mortgage brokers, there is no allocation in the commercial segment displayed in the following tables based on historical loss factors. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.

Internally assigned credit risk ratings are reviewed, at a minimum, when loans are renewed or when management has knowledge of improvements or deterioration of the credit quality of individual credits. Descriptions of the internally assigned credit risk ratings for commercial and agricultural loans are as follows:
1. EXCELLENT – Substantially Risk Free
Credit has strong financial condition and solid earnings history, characterized by:

• | High liquidity, strong cash flow, low leverage.

• | Unquestioned ability to meet all obligations when due.

• | Experienced management, with management succession in place.

• | Secured by cash.

2. HIGH QUALITY – Limited Risk
Credit with sound financial condition and a positive trend in earnings supplemented by:

• | Favorable liquidity and leverage ratios.

• | Ability to meet all obligations when due.

• | Management with successful track record.

• | Steady and satisfactory earnings history.

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

• | Access to alternative financing.

18

Table of Contents

• | Well defined primary and secondary source of repayment.

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

3. HIGH SATISFACTORY – Reasonable Risk
Credit with satisfactory financial condition and further characterized by:

• | Working capital adequate to support operations.

• | Cash flow sufficient to pay debts as scheduled.

• | Management experience and depth appear favorable.

• | Loan performing according to terms.

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

4. LOW SATISFACTORY – Acceptable Risk
Credit with bankable risks, although some signs of weaknesses are shown:

• | Would include most start-up businesses.

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

• | Management’s abilities are apparent, yet unproven.

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

• | Loan structure generally in accordance with policy.

• | If secured, loan collateral coverage is marginal.

• | Adequate cash flow to service debt, but coverage is low.

To be classified as less than satisfactory, only one of the following criteria must be met.
5. SPECIAL MENTION – Criticized
Credit constitutes an undue and unwarranted credit risk but not to the point of justifying a classification of substandard. The credit risk may be relatively minor yet constitute an unwarranted risk in light of the circumstances surrounding a specific loan:

• | Downward trend in sales, profit levels, and margins.

• | Impaired working capital position.

• | Cash flow is strained in order to meet debt repayment.

• | Loan delinquency (30-60 days) and overdrafts may occur.

• | Shrinking equity cushion.

• | Diminishing primary source of repayment and questionable secondary source.

• | Management abilities are questionable.

• | Weak industry conditions.

• | Litigation pending against the borrower.

• | Collateral or guaranty offers limited protection.

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

6. SUBSTANDARD – Classified
Credit where the borrower’s current net worth, paying capacity, and value of the collateral pledged is inadequate. There is a distinct possibility that we will implement collection procedures if the loan deficiencies are not corrected. In addition, the following characteristics may apply:

• | Sustained losses have severely eroded the equity and cash flow.

• | Deteriorating liquidity.

• | Serious management problems or internal fraud.

• | Original repayment terms liberalized.

• | Likelihood of bankruptcy.

• | Inability to access other funding sources.

• | Reliance on secondary source of repayment.

• | Litigation filed against borrower.

• | Collateral provides little or no value.

• | Requires excessive attention of the loan officer.

• | Borrower is uncooperative with loan officer.

7. VULNERABLE – Classified
Credit is considered “Substandard” and warrants placing on nonaccrual status. Risk of loss is being evaluated and exit strategy options are under review. Other characteristics that may apply:

• | Insufficient cash flow to service debt.

• | Minimal or no payments being received.

• | Limited options available to avoid the collection process.

• | Transition status, expect action will take place to collect loan without immediate progress being made.

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

• | Normal operations are severely diminished or have ceased.

• | Seriously impaired cash flow.

• | Original repayment terms materially altered.

• | Secondary source of repayment is inadequate.

• | Survivability as a “going concern” is impossible.

• | Collection process has begun.

• | Bankruptcy petition has been filed.

• | Judgments have been filed.

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

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

1. | There has been a charge-off of its principal balance (in whole or in part);

2. | The loan has been classified as a TDR; or

3. | The loan is in nonaccrual status.

Impairment is measured on a loan-by-loan basis for commercial and agricultural loans by comparing the loan’s outstanding balance to the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral, less cost to sell, if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Impairment is measured on a loan-by-loan basis for residential real estate and consumer loans by comparing the loan’s unpaid principal balance to the present value of expected future cash flows discounted at the loan’s effective interest rate.

Table of Contents
We do not recognize interest income on impaired loans in nonaccrual status. For impaired loans not classified as nonaccrual, interest income is recognized daily, as earned, according to the terms of the loan agreement and the principal amount outstanding.

We had committed to advance $637 and $472 in connection with impaired loans, which includes TDRs, as of March 31, 2018 and December 31, 2017, respectively.
Troubled Debt Restructurings
Loan modifications are considered to be TDRs when the modification includes terms outside of normal lending practices to a borrower who is experiencing financial difficulties.
Typical concessions granted include, but are not limited to:
•Agreeing to interest rates below prevailing market rates for debt with similar risk characteristics.
•Extending the amortization period beyond typical lending guidelines for loans with similar risk characteristics.
•Agreeing to an interest only payment structure and delaying principal payments.
•Forgiving principal.
•Forgiving accrued interest.
To determine if a borrower is experiencing financial difficulties, factors we consider include:

• | The borrower is currently in default on any of their debt.

• | The borrower would likely default on any of their debt if the concession was not granted.

• | The borrower’s cash flow was insufficient to service all of their debt if the concession was not granted.

• | The borrower has declared, or is in the process of declaring, bankruptcy.

• | The borrower is unlikely to continue as a going concern (if the entity is a business).

We did not restructure any loans by forgiving principal or accrued interest in the three month periods ended March 31, 2018 or 2017.
Based on our historical loss experience, losses associated with TDRs are not significantly different than other impaired loans within the same loan segment. As such, TDRs, including TDRs that have been modified in the past 12 months that subsequently defaulted, are analyzed in the same manner as other impaired loans within their respective loan segment.
We had no loans that defaulted in the three month periods ended March 31, 2018 and March 31, 2017 which were modified within 12 months prior to the default date.
The following is a summary of TDR loan balances as of:

AFS securities pledged to repurchase agreements are monitored to ensure the appropriate level is collateralized. In the event of maturities, calls, significant principal repayments, or significant decline in market values, we have adequate levels of AFS securities to pledge to satisfy required collateral.
As of March 31, 2018, we had the ability to borrow up to an additional $153,347, based on assets pledged as collateral. We had no investment securities that are restricted to be pledged for specific purposes.
Derivative Instruments
We enter into interest rate swaps to manage exposure to interest rate risk and variability in cash flows. The interest rate swaps, associated with our variable rate borrowings, are designated upon inception as cash flow hedges of forecasted interest payments. We enter into LIBOR-based interest rate swaps that involve the receipt of variable amounts in exchange for fixed rate payments, in effect converting variable rate debt to fixed rate debt.
Cash flow hedges are assessed for effectiveness using regression analysis. The effective portion of changes in fair value are recorded in OCI and subsequently reclassified into interest expense in the same period in which the related interest on the variable rate borrowings affects earnings. In the event that a portion of the changes in fair value were determined to be ineffective, the ineffective amount would be recorded in earnings.

Derivatives contain an element of credit risk which arises from the possibility that we will incur a loss as a result of a counterparty failing to meet its contractual obligations. Credit risk is minimized through counterparty collateral, transaction limits and monitoring procedures. We also manage dealer credit risk by entering into interest rate derivatives only with primary and highly rated counterparties, the use of ISDA master agreements and counterparty limits. We do not anticipate any losses from failure of interest rate derivative counterparties to honor their obligations.
Note 8 – Revenue
Our revenue is comprised primarily of interest income, service charges and fees, gains on the sale of loans and AFS securities, earnings on corporate owned life insurance policies, and other noninterest income. Other noninterest income is typically service and performance driven in nature and comprised primarily of trust and brokerage advisory fees. We recognize revenue in accordance with GAAP as outlined in ASC 606, Revenue From Contracts with Customers. Revenue is recognized when our performance obligation has been satisfied according to our contractual obligation.
We record receivables when revenue is unpaid and collectability is reasonably assured. Accounts receivable balances primarily represent amounts due from customers for which revenue has been recognized. Accounts receivable balances are recorded in the consolidated balance sheets in accrued interest receivable and other assets. For the three month periods ended March 31, 2018 and 2017, we satisfied our performance obligations pursuant to contracts with customers. As a result, we have not recorded contract assets or liabilities. We estimate no returns or allowances for the three month periods ended March 31, 2018 and 2017.
Our contracts with customers define our performance obligations with clearly established pricing which did not require us to allocate or disaggregate revenue by performance obligation. A summary of revenue recognized for each major category of contracts with customers, subject to ASC 606, is as follows for the:

| Three Months Ended March 31
| 2018 |  | 2017
Debit card income | $ | 588 |  |  | $ | 530 |

Service charges and fees related to deposit accounts | 85 |  |  | 85 |
Total | $ | 1,331 |  |  | $ | 1,186 |

A large portion of our revenue consists of interest income which is not subject to the requirements set forth in ASU 2014-09. This recently adopted guidance required us to review our other noninterest revenue sources within the scope of the guidance to ensure appropriate recognition of revenue from contracts with customers. This review process did not identify significant changes related to revenue recognition. As such, we did not record or disclose transactions related to the adoption of this guidance.

Note 11 – Fair Value
Under fair value measurement and disclosure authoritative guidance, we group assets and liabilities measured at fair value into three levels, based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine fair value, based on the prioritization of inputs in the valuation techniques. These levels are:

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

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. Transfers between measurement levels are recognized at the end of reporting periods.
Fair value measurement requires the use of an exit price notion which may differ from entrance pricing. Generally we believe our assets and liabilities classified as Level 1 or Level 2 approximate an exit price notion.
Following is a description of the valuation methodologies, key inputs, and an indication of the level of the fair value hierarchy in which the assets or liabilities are classified.
AFS securities: AFS securities are recorded at fair value on a recurring basis. Level 1 fair value measurement is based upon quoted prices for identical instruments. Level 2 fair value measurement is based upon quoted prices for similar instruments. If quoted prices are not available, fair values are measured using independent pricing models or other model based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss and liquidity assumptions. The values for Level 1 and Level 2 investment securities are generally obtained from an independent third party. On a quarterly basis, we compare the values provided to alternative pricing sources.
Equity securities, at fair value: Equity securities are recorded at fair value on a recurring basis. Level 1 fair value measurement is based upon quoted prices for identical instruments. The values for Level 1 investment securities are generally obtained from an independent third party. On a quarterly basis, we compare the values provided to alternative pricing sources.
Loans: We do not record loans at fair value on a recurring basis. However, from time-to-time, loans are classified as impaired and a specific allowance for loan losses may be established. Loans for which it is probable that payment of interest and principal will be significantly different than the contractual terms of the original loan agreement are considered impaired. Once a loan is identified as impaired, we measure the estimated impairment. The fair value of impaired loans is estimated using one of several methods, including the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral, less costs to sell, if the loan is collateral dependent. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans.
We review the net realizable values of the underlying collateral for collateral dependent impaired loans on at least a quarterly basis for all loan types. To determine the collateral value, we utilize independent appraisals, broker price opinions, or internal evaluations. We review these valuations to determine whether an additional discount should be applied given the age of market information that may have been considered as well as other factors such as costs to sell an asset if it is determined that the collateral will be liquidated in connection with the ultimate settlement of the loan. We use these valuations to determine if any specific reserves or charge-offs are necessary. We may obtain new valuations in certain circumstances, including when there has been significant deterioration in the condition of the collateral, if the foreclosure process has begun, or if the existing valuation is deemed to be outdated.

| March 31, 2018

|  | Accounts receivable |  | 50%
|  | Liquor license |  | 75%
|  | Furniture, fixtures & equipment |  | 35% - 45%

Collateral discount rates may have ranges to accommodate differences in the age of the independent appraisal, broker price opinion, or internal evaluation.
Derivative instruments: Derivative instruments, consisting solely of interest rate swaps, are recorded at fair value on a recurring basis. Derivatives qualifying as cash flow hedges, when highly effective, are reported at fair value in other assets or other liabilities on our Consolidated Balance Sheets with changes in value recorded in OCI. Should the hedge no longer be considered effective, the ineffective portion of the change in fair value is recorded directly in earnings in the period in which the change occurs. The fair value of a derivative is determined by quoted market prices and model based valuation techniques. As such, we classify derivative instruments as Level 2.
The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Although we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement.

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

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.
ISABELLA BANK CORPORATION FINANCIAL REVIEW
(Dollars in thousands except per share amounts)
This section reviews our financial condition and results of our operations for the unaudited three month periods ended March 31, 2018 and 2017. This analysis should be read in conjunction with our 2017 Annual Report on Form 10-K and with the unaudited interim condensed consolidated financial statements and notes, beginning on page 4 of this report.
Executive Summary
During the three months ended March 31, 2018, the Corporation reported net income of $3,462 and earnings per common share of $0.44. Net income and earnings per common share for the same period of 2017 was $3,136 and $0.40, respectively. The increase of $326 in year-to-date earnings was driven, in part, by a significant increase in interest income as the result of strong loan growth, which totaled $80,082 during the prior 12 months. Net interest income increased by $690 for the first three months of 2018 in comparison to the same period in 2017. Provision for loan losses increased by $357 for the first three months of 2018 in comparison to the same period in 2017 as a result of a combination of loan growth and an increase in nonperforming agricultural loans. Strong operating expense controls were maintained with expenses increasing by only $145 when comparing the same two periods. In addition, net income in 2018 has benefited from the lower federal statutory tax rate established by the 2017 Tax Act.
As of March 31, 2018, total assets and assets under management were $1,799,592 and $2,532,711, respectively, with both decreasing slightly from December 31, 2017. Assets under management include loans sold and serviced of $262,541 and assets managed by our Investment and Trust Services Department of $470,578. Loans outstanding as of March 31, 2018 totaled $1,093,002. While loans grew as anticipated during the first quarter of 2018, total deposits increased $32,610 which exceeded expectations and allowed us to reduce borrowed funds by $41,765. All regulatory capital ratios for the Bank exceeded the minimum thresholds to be considered a "well capitalized" institution.
Our net yield on interest earning assets (FTE) was 2.95% for the three month period ended March 31, 2018. The decline in our net yield on interest earning assets during the quarter from 3.02% in the prior quarter was driven by a decrease in our FTE yield on nontaxable investment securities due to the lower federal statutory tax rate established by the 2017 Tax Act. The FRB increased short-term interest rates during the first quarter of 2018 and projects further increases in 2018. We anticipate improvements in our net yield on interest earning assets as a result of a combination of projected FRB short-term rate increases, assets repricing faster than liabilities, our asset mix shifting to an increasing percentage of loans compared to investment securities, and strategic growth in loans and other income earning assets. We are committed to increasing earnings and shareholder value through growth in our loan portfolio, growth in our investment and trust services, and increasing our geographical presence while managing operating costs.
Recent Legislation
On December 22, 2017, the Tax Cuts and Jobs Act was enacted. The new law establishes a flat corporate federal statutory income tax rate of 21%, a decline from 34%, and eliminates the corporate alternative minimum tax. The new tax law provides for a wide array of changes with only some believed to have a direct impact on our federal income tax expense. Some of these changes include, but are not limited to, the following items: limits to the deductions for net interest expense, immediate expense (for tax purposes) for certain qualified depreciable assets, elimination or reduction of certain deductions related to meals and entertainment expenses, and limits to the deductibility of deposit insurance premiums.
Reclassifications: Certain amounts reported in the 2017 consolidated financial statements have been reclassified to conform to the 2018 presentation.

Net Interest Income
Net interest income is the amount by which interest income on earning assets exceeds the interest expenses on interest bearing liabilities. Net interest income, which includes loan fees, is influenced by changes in the balance and mix of assets and liabilities and market interest rates. We exert some control over these factors; however, FRB monetary policy and competition have a significant impact. For analytical purposes, net interest income is adjusted to an FTE basis by adding the income tax savings from interest on tax exempt loans, and nontaxable investment securities, thus making year to year comparisons more meaningful.
Volume and Rate Variance Analysis
The following table sets forth the effect of volume and rate changes on interest income and expense for the periods indicated. For the purpose of this table, changes in interest due to volume and rate were determined as follows:
Volume—change in volume multiplied by the previous period's rate.
Rate—change in the FTE rate multiplied by the previous period's volume.
The change in interest due to both volume and rate has been allocated to volume and rate changes in proportion to the relationship of the absolute dollar amounts of the change in each.

Our net yield on interest earning assets decreased during the quarter with yields remaining at low levels. The decline in our yield on interest earning assets during the quarter was driven by a decline in our FTE yield on nontaxable investment securities due to the lower federal statutory tax rate established by the 2017 Tax Act. The persistent low interest rate environment coupled with a high concentration of AFS securities as a percentage of earning assets has also placed downward pressure on net interest margin. While we do not anticipate significant improvement in our net yield on interest earning assets, we do expect marginal improvement as a result of loan growth throughout 2018.

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

While we experienced net loan recoveries during the quarter, we also experienced deterioration in credit quality indicators evidenced in part by our level of nonperforming loans. These indicators required an increase in both the ALLL balance and the ALLL as a percentage of loans. During the past year, strong credit quality indicators, low historical loss factors, and net loan recoveries have resulted in modest levels of required reserves. While the ALLL as a percentage of loans has increased only slightly, the balance of the ALLL has increased as a result of our strong loan growth.
The following table illustrates our changes within the two main components of the ALLL as of:

| March 31 2018 |  | December 31 2017 |  | September 30 2017 |  | June 30 2017 |  | March 31 2017

Loans Past Due and Loans in Nonaccrual Status
Fluctuations in past due and nonaccrual status loans can have a significant impact on the ALLL. To determine the potential impact, and corresponding estimated losses, we analyze our historical loss trends on loans past due greater than 30 days and nonaccrual status loans. We monitor all loans that are past due and in nonaccrual status for indications of additional deterioration.

| Total Past Due and Nonaccrual Loans
| March 31 2018 |  | December 31 2017 |  | September 30 2017 |  | June 30 2017 |  | March 31 2017
Commercial and agricultural | $ | 9,398 |  |  | $ | 4,885 |  |  | $ | 3,600 |  |  | $ | 4,920 |  |  | $ | 5,758 |
Residential real estate | 4,614 |  |  | 4,881 |  |  | 2,201 |  |  | 2,358 |  |  | 3,168 |
Consumer | 115 |  |  | 70 |  |  | 52 |  |  | 64 |  |  | 35 |
Total | $ | 14,127 |  |  | $ | 9,836 |  |  | $ | 5,853 |  |  | $ | 7,342 |  |  | $ | 8,961 |
Total past due and nonaccrual loans to gross loans | 1.29 | % |  | 0.90 | % |  | 0.54 | % |  | 0.70 | % |  | 0.88 | %

While past due and nonaccrual status loans have fluctuated over the last year, they continue to reflect strong loan performance. The recent increase resulted primarily from commercial and agricultural loan activity, which is being closely monitored. A summary of loans past due and in nonaccrual status, including the composition of the ending balance of nonaccrual status loans by type, is included in “Note 5 – Loans and ALLL” of our interim condensed consolidated financial statements.

Troubled Debt Restructurings
We have taken a proactive approach to avoid foreclosures on borrowers who are willing to work with us in modifying their loans, thus making them more affordable. While this approach has permitted certain borrowers to develop a payment structure that will allow them to continue making payments in lieu of foreclosure, it has contributed to a significant level of loans classified as TDR. The modifications have been successful for us and our customers as very few of the modified loans have resulted in foreclosures. At the time of the TDR, the loan is reviewed to determine whether or not to classify the loan as accrual or nonaccrual status. The majority of new modifications result in terms that satisfy our criteria for continued interest accrual. TDRs that have been placed on nonaccrual status may be placed back on accrual status after six months of continued performance and achievement of current payment status.
We restructure debt with borrowers who, due to financial difficulties, are unable to service their debt under the original terms. We may extend the amortization period, reduce interest rates, allow interest only payment structures, forgive principal, forgive interest, or a combination of these modifications. Typically, the modifications are for a period of five years or less. There were no TDRs that were government sponsored as of March 31, 2018 or December 31, 2017.
Losses associated with TDRs, if any, are included in the estimation of the ALLL in the quarter in which a loan is identified as a TDR, and we review the analysis of the ALLL estimation each reporting period to ensure its continued appropriateness.
The following tables provide a roll-forward of TDRs for the:

Typically after a loan is 90 days past due, it is placed on nonaccrual status unless it is well secured and in the process of collection. Upon transferring the loans to nonaccrual status, we perform an evaluation to determine the net realizable value of the underlying collateral. This evaluation is used to help determine if any charge-offs are necessary. Loans may be placed back on accrual status after six months of continued performance and achievement of current payment status. While the level of nonperforming loans has recently increased, it remains low.
Included in the nonaccrual loan balances above were loans currently classified as TDR as of:

| March 31 2018 |  | December 31 2017
Commercial and agricultural | $ | 2,592 |  |  | $ | 2,679 |
Residential real estate | 598 |  |  | 234 |
Total | $ | 3,190 |  |  | $ | 2,913 |

Additional disclosures about nonaccrual status loans are included in “Note 5 – Loans and ALLL” of our interim condensed consolidated financial statements.
We continue to devote considerable attention to identifying impaired loans and adjusting the net carrying value of these loans to their current net realizable values through the establishment of a specific reserve or the recording of a charge-off. We believe that we have identified all impaired loans as of March 31, 2018.
We believe that the level of the ALLL is appropriate as of March 31, 2018. We will continue to closely monitor overall credit quality indicators and our policies and procedures related to the analysis of the ALLL to ensure that the ALLL remains at the appropriate level.

Total noninterest income | $ | 2,487 |  |  | $ | 2,616 |  |  | $ | (129 | ) |  | (4.93 | )%

Significant changes in noninterest income are detailed below:

• | ATM and debit card fees fluctuate from period-to-period based primarily on usage of ATM and debit cards. While we do not anticipate significant changes to our ATM and debit card fee transaction charges, we do expect that fee income will continue to increase in 2018 as the trend of ATM and debit card usage continues to increase.

• | An OMSR asset represents the present value of the amount by which the estimated future net cash flows from servicing mortgage loans that were sold on a servicing-retained basis exceeds the cost of servicing those mortgage loans. OMSR income (loss) results when the OMSR value changes. Generally, rising residential mortgage loan offering rates result in decreased prepayments in the servicing-retained portfolio, which results in increased estimated future net cash flows. OMSR income may increase during the remainder of 2018, primarily as a result of expected offering rate increases, but may not exceed 2017 OMSR income.

• | We anticipate increases in our originations in purchase money mortgage activity as a result of our various initiatives to drive growth. As a result, we expect net gains on the sale of mortgage loans to increase during the remainder of 2018 but may not exceed 2017 levels.

• | In recent periods, we have invested considerable efforts to increase our market penetration with investment and trust services. We anticipate that this fee income will continue to increase during the remainder of 2018 and exceed 2017 levels.

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

Significant changes in noninterest expenses are detailed below:

• | The decline in employee benefits is related to health care costs as a result of lower than anticipated claims. Employee benefits are expected to increase moderately during the remainder of 2018 as a result of anticipated increases in health care costs.

• | Computer expense increased in 2018 due to data and system upgrades, additional network security costs, and one-time implementation costs. Expenses in 2018 are expected to continue to exceed 2017 levels.

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

As shown above, total assets have decreased since December 31, 2017. As expected, gross loans increased only slightly during the first quarter of 2018. While generating quality loans in a competitive market continues to be challenging, we expect that loans will continue to grow in 2018. During the first three months of 2018, we have experienced deposit growth which allowed us to reduce borrowed funds.

The balance of AFS securities fluctuates from period-to-period based on changes in loans and deposits. While loan growth has been strong over the last year, we purchased AFS securities in periods when deposit growth outpaced loan demand. Conversely, we have sold AFS securities in periods when loan demand has outpaced deposit growth. We remain active in investments with our local schools and municipalities. The following table displays fair values of AFS securities as of:

Borrowed funds include FHLB advances, securities sold under agreements to repurchase, and federal funds purchased. The balance of borrowed funds fluctuates from period-to-period based on our funding needs including changes in loans, investments, and deposits. To provide balance sheet growth, we utilize borrowings and brokered deposits to fund earning assets. The following table displays borrowed funds balances as of:

Contractual Obligations and Loan Commitments
We are party to credit related financial instruments with off-balance-sheet risk. These financial instruments are entered into in the normal course of business to meet the financing needs of our customers. These financial instruments 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 we have in a particular class of financial instrument.
The following table summarizes our credit related financial instruments with off-balance-sheet risk as of:

| March 31 2018 |  | December 31 2017
Unfunded commitments under lines of credit | $ | 184,040 |  |  | $ | 184,317 |
Commitments to grant loans | 37,838 |  |  | 24,782 |
Commercial and standby letters of credit | 1,622 |  |  | 1,622 |
Total | $ | 223,500 |  |  | $ | 210,721 |

Unfunded commitments under lines of credit are commitments for possible future extensions of credit to existing customers. These commitments may expire without being drawn upon and do not necessarily represent future cash requirements. Advances to mortgage brokers are also included in unfunded commitments under lines of credit. The unfunded commitment amount is the difference between our outstanding balances and the maximum outstanding aggregate amount.
Commitments to grant loans are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The amount of collateral obtained, if it is deemed necessary, is based on management’s credit evaluation of the customer. Commitments to grant loans include residential mortgage loans that may be committed to be sold to the secondary market.
Commercial and standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing arrangements, including commercial paper, bond financing, and similar transactions. These commitments to extend credit and letters of credit generally mature within one year. The credit risk involved in these transactions is essentially the same as that involved in extending loans to customers. We evaluate each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary

upon the extension of credit, is based on a credit evaluation of the borrower. While we consider standby letters of credit to be guarantees, the amount of the liability related to such guarantees on the commitment date is not significant and a liability related to such guarantees is not recorded on the consolidated balance sheets.
Our exposure to credit-related loss in the event of nonperformance by the counter parties to the financial instruments for commitments to extend credit and standby letters of credit could be up to the contractual notional amount of those instruments. We use the same credit policies as we do for extending loans to customers. No significant losses are anticipated as a result of these commitments.
Capital
Capital consists solely of common stock, retained earnings, and accumulated other comprehensive income (loss). We are authorized to raise capital through dividend reinvestment, employee and director stock purchases, and shareholder stock purchases. Pursuant to these authorizations, we issued 59,560 shares or $1,616 of common stock during the first three months of 2018, as compared to 63,866 shares or $1,770 of common stock during the same period in 2017. We also offer the Directors Plan in which participants either directly purchase stock or purchase stock units through deferred fees, in lieu of cash payments. Pursuant to this plan, we increased shareholders’ equity by $146 and $178 during the three month periods ended March 31, 2018 and 2017, respectively.
We have a publicly announced common stock repurchase plan. Pursuant to this plan, we repurchased 22,512 shares or $620 of common stock during the first three months of 2018 and 41,815 shares or $1,169 during the first three months of 2017. As of March 31, 2018, we were authorized to repurchase up to an additional 193,159 shares of common stock.
The FRB has established minimum risk based capital guidelines. Pursuant to these guidelines, a framework has been established that assigns risk weights to each category of on and off-balance-sheet items to arrive at risk adjusted total assets. Regulatory capital is divided by the risk adjusted assets with the resulting ratio compared to the minimum standard to determine whether a corporation has adequate capital. On July 2, 2013, the FRB published revised BASEL III Capital standards for banks. The final rules redefine what is included or deducted from equity capital, changes risk weighting for certain on and off-balance sheet assets, increases the minimum required equity capital to be considered well capitalized, and introduces a capital conservation buffer. The rules, which are being gradually phased in between 2015 and 2019, are not expected to have a material impact on the Corporation but will require us to hold more capital than has historically been required.
There are no significant regulatory constraints placed on our capital. The FRB’s current recommended minimum primary capital to assets requirement is 6.00%. Our primary capital to adjusted average assets, or tier 1 leverage ratio, was 8.69% as of March 31, 2018.
Effective January 1, 2015, the minimum standard for primary, or Tier 1 capital, increased from 4.00% to 6.00%. The minimum standard for total capital is 8.00%. Also effective January 1, 2015 was the new common equity tier 1 capital ratio which had a minimum requirement of 4.50%. Beginning on January 1, 2016 the capital conservation buffer went into effect which will further increase the required levels each year through 2019. The following table sets forth the percentages required under the Risk Based Capital guidelines and our ratios as of:

| March 31, 2018 |  | December 31, 2017
| Actual |  | Minimum Required |  | Actual |  | Minimum Required
Common equity tier 1 capital | 12.340 | % |  | 6.375 | % |  | 12.230 | % |  | 5.750 | %
Tier 1 capital | 12.340 | % |  | 7.875 | % |  | 12.230 | % |  | 7.250 | %
Tier 2 capital | 0.670 | % |  | 2.000 | % |  | 0.630 | % |  | 2.000 | %
Total Capital | 13.010 | % |  | 9.875 | % |  | 12.860 | % |  | 9.250 | %

Tier 2 capital, or secondary capital, includes only the ALLL. The percentage for the secondary capital under the required column is the maximum amount allowed from all sources.
The FRB and FDIC also prescribe minimum capital requirements for Isabella Bank. At March 31, 2018, the Bank exceeded these minimum capital requirements.

Fair Value
We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. AFS securities, cash flow hedge derivative instruments and certain liabilities are recorded at fair value on a recurring basis. Additionally, from time-to-time, we may be required to record at fair value other assets on a nonrecurring basis, such as mortgage loans AFS, impaired loans, goodwill, foreclosed assets, OMSR, and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write-downs of individual assets.
For further information regarding fair value measurements see “Note 11 – Fair Value” of our notes to the interim condensed consolidated financial statements.
Liquidity
Liquidity is monitored regularly by our Market Risk Committee, which consists of members of senior management. The committee reviews projected cash flows, key ratios, and liquidity available from both primary and secondary sources.
Our primary sources of liquidity are cash and cash equivalents and unencumbered AFS securities. These categories totaled $285,657 or 15.87% of assets as of March 31, 2018, compared to $293,188 or 16.17% as of December 31, 2017. The decrease in primary liquidity is a direct result of our unencumbered AFS securities activity during 2017. 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 could vary significantly daily, based on customer activity.
Our primary source of funds is through deposit accounts. We also have the ability to borrow from the FHLB, the FRB, and through various correspondent banks in the form of federal funds purchased and a line of credit. These funding methods typically carry a higher interest rate than traditional market deposit accounts. Some borrowed funds, including FHLB advances, FRB Discount Window advances, and repurchase agreements, require us to pledge assets, typically in the form of AFS securities or loans, as collateral. As of March 31, 2018, we had available lines of credit of $153,347.
The following table summarizes our sources and uses of cash for the three month period ended March 31:

| 2018 |  | 2017 |  | $ Variance
Net cash provided by (used in) operating activities | $ | 5,810 |  |  | $ | 4,387 |  |  | $ | 1,423 |

Market Risk
Our primary market risks are interest rate risk and liquidity risk. We have no significant foreign exchange risk in the management of IRR. Any changes in foreign exchange rates or commodity prices would have an insignificant impact on our interest income and cash flows.
IRR is the exposure of our net interest income to changes in interest rates. IRR results from the difference in the maturity or repricing frequency of a financial institution's interest earning assets and its interest bearing liabilities. IRR is the fundamental method by which financial institutions earn income and create shareholder value. Excessive exposure to IRR could pose a significant risk to our earnings and capital.
The FRB has adopted a policy requiring us to effectively manage the various risks that can have a material impact on our safety and soundness. The risks include credit, interest rate, liquidity, operational, and reputational. We have policies, procedures, and internal controls for measuring and managing these risks. Specifically, our Funds Management policy and procedures include defining acceptable types and terms of investments and funding sources, liquidity requirements, limits on investments in long term assets, limiting the mismatch in repricing opportunity of assets and liabilities, and the frequency of measuring and reporting to our Board.
The primary technique to measure IRR is simulation analysis. Simulation analysis forecasts the effects on the balance sheet structure and net interest income under a variety of scenarios that incorporate changes in interest rates, the shape of yield curves, interest rate relationships, loan prepayments, and changes in funding sources. These forecasts are compared against net interest income projected in a stable interest rate environment. While many assets and liabilities reprice either at maturity or in accordance with their contractual terms, several balance sheet components demonstrate characteristics that require an evaluation to more accurately reflect their repricing behavior. Key assumptions in the simulation analysis include prepayments on loans, probable calls of investment securities, changes in market conditions, loan volumes and loan pricing, deposit sensitivity, and customer preferences. These assumptions are inherently uncertain as they are subject to fluctuation and revision in a dynamic environment. As a result, the simulation analysis cannot precisely forecast the impact of rising and falling interest rates on net interest income. Actual results will differ from simulated results due to many other factors, including changes in balance sheet components, interest rate changes, changes in market conditions, and management strategies.
Our interest rate sensitivity is estimated by first forecasting the next 12 and 24 months of net interest income under an assumed environment of a constant balance sheet and constant market interest rates (base case). We then compare the results of various simulation analyses to the base case. At March 31, 2018, we projected the change in net interest income during the next 12 and 24 months assuming market interest rates were to immediately decrease by 100 basis points and increase by 100, 200, 300, and 400 basis points in a parallel fashion over the entire yield curve during the same time period. We did not project scenarios showing decreases in interest rates beyond 100 basis points as this is considered extremely unlikely given current interest rate levels. These projections were based on our assets and liabilities remaining static over the next 12 and 24 months, while factoring in probable calls and prepayments of certain investment securities and residential real estate and consumer loans. While it is extremely unlikely that interest rates would immediately increase to these levels, we feel that these extreme scenarios help us identify potential gaps and mismatches in the repricing characteristics of assets and liabilities. We regularly monitor our projected net interest income sensitivity to ensure that it remains within established limits. As of March 31, 2018, our interest rate sensitivity results were within Board approved limits.
The following tables summarize our interest rate sensitivity for the next 12 and 24 months as of:
