NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 - Summary of Significant Accounting Policies

     Consolidation: Irwin Financial Corporation and its subsidiaries (the Corporation) provide financial services throughout the United States and Canada. We are engaged in the mortgage banking, commercial banking, home equity lending, and commercial finance lines of business. Our direct and indirect subsidiaries include Irwin Mortgage Corporation, Irwin Union Bank and Trust Company, Irwin Union Bank, F.S.B., Irwin Home Equity Corporation, and Irwin Commercial Finance Corporation. Intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, the financial statements reflect all material adjustments necessary for a fair presentation. The Corporation does not meet the criteria as primary beneficiary for our wholly-owned trusts holding our company-obligated mandatorily redeemable preferred securities established by Financial Accounting Standards Board (FASB) Interpretation No. 46 (FIN 46), “Consolidation of Variable Interest Entities.” As a result, these trusts are not consolidated.

     Use of Estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

     Cash and Cash Equivalents Defined: For purposes of the statement of cash flows, we consider cash and due from banks and federal funds sold to be cash equivalents.

     Residual Interests: Residual interests are stated at fair value. Unrealized gains and losses are included in earnings. To obtain fair value of residual interests, quoted market prices are used if available. However, quotes are generally not available for residual interests, so we generally estimate fair value based on the present value of expected cash flows using estimates of the key assumptions - prepayment speeds, credit losses, forward yield curves, and discount rates commensurate with the risks involved - that management believes market participants would use to value similar assets. Adjustments to carrying values are recorded as “trading gains or losses.”

     Allowance for Loan and Lease Losses: The allowance for loan and lease losses is an estimate based on management’s judgment applying the principles of Statement of Financial Accounting Standard (SFAS) 5, “Accounting for Contingencies,” SFAS 114, “Accounting by Creditors for Impairment of a Loan,” and SFAS 118, “Accounting by Creditors for Impairment of a Loan - Income Recognition and Disclosures.” The allowance is maintained at a level we believe is adequate to absorb probable losses inherent in the loan and lease portfolio. We perform an assessment of the adequacy of the allowance on a quarterly basis.

     Within the allowance, there are specific and expected loss components. The specific loss component is assessed for loans we believe to be impaired in accordance with SFAS 114. We have defined impairment as nonaccrual loans. For loans determined to be impaired, we measure the level of impairment by comparing the loan’s carrying value to fair value using one of the following fair value measurement techniques: present value of expected future cash flows, observable market price, or fair value of the associated collateral. An allowance is established when the fair value implies a value that is lower than the carrying value of that loan. In addition to establishing allowance levels for specifically identified higher risk graded loans, management determines an allowance for all other loans in the portfolio for which historical experience indicates that certain losses exist. These loans are segregated by major product type, and in some instances, by aging, with an estimated loss ratio applied against each product type and aging category. The loss ratio is generally based upon historic loss experience for each loan type as adjusted for certain environmental factors management believes to be relevant.

     Servicing Assets: When we securitize or sell loans, we generally retain the right to service the underlying loans sold. A portion of the cost basis of loans sold is allocated to this servicing asset based on its fair value relative to the loans sold and the servicing asset combined. We use the market prices under comparable servicing sale contracts, when available, or alternatively use valuation models that calculate the present value of future cash flows to determine the fair value of the servicing assets. In using this valuation method, we incorporate assumptions that we believe market participants would use in estimating future net servicing income, which include estimates of the cost of servicing per loan, the discount rate, float value, an inflation rate, ancillary income per loan, prepayment speeds, and default rates. Servicing assets are amortized over the estimated lives of the related loans in proportion to estimated net servicing income.

     In determining servicing value impairment, the servicing portfolio is stratified into its predominant risk characteristics, principally by interest rate and product type. Each stratum is valued using market prices under comparable servicing sale contracts

when available, or alternatively, using the same model as was used originally to determine the fair value at origination using current market assumptions. The calculated value is then compared with the book value of each stratum to determine the required reserve for impairment. The impairment reserve fluctuates as interest rates change and, therefore, no reasonable estimate can be made as to future increases or declines in impaired reserve levels. We also compare actual cash collections to projected cash collections and adjust our models as appropriate. In addition, we periodically have independent valuations performed on the portfolio. Other than temporary impairment is recorded to reflect our view that the originally recorded value of certain servicing rights and subsequent impairment associated with those rights is unlikely to be recovered in market value. There is no related direct impact on net income as this other than temporary impairment affects only balance sheet accounts. However, a write-down will result in a reduction of amortization expense and potentially reduced recovery of impairment in future periods.

     Incentive Servicing Fees: For whole loan sales of certain home equity loans, we have the right to an incentive servicing fee (ISF) that will provide cash payments to us if a pre-established return for the certificate holders and certain structure-specific loan credit and servicing performance metrics are met. These ISF contracts are treated as derivatives under SFAS 133, “Accounting for Derivative Instruments and Hedging Activities,” and classified in “other assets.” When we first received cash from an ISF agreement in the first quarter of 2004, our accounting policy reflected the lack of history for these cash flows and among other factors, required projections of expected cash flows to occur within one year before recognizing any value. In the first quarter of 2005 we concluded our actual servicing experience and the performance of the loan pools subject to these ISFs has now demonstrated a level of predictability that has allowed us to modify our accounting policy to eliminate the one year to cash flow requirement and, as appropriate under SFAS 133, recognize derivative value for cash flows expected over time, including ones not anticipated to occur within one year. Our policy requires discounting these derivatives at rates between 20% and 40%, depending on a variety of factors, including volatility of anticipated cash flow, credit quality, loan-to-value ratio, and anticipated prepayment speeds. ISFs are carried at fair value with the changes to fair value recognized in “derivative gains/losses.”

     Stock-Based Employee Compensation: We have three stock-based employee compensation plans. We use the intrinsic value method to account for our plans under the recognition and measurement principles of APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations. No stock-based employee compensation cost is reflected in net income for any of the periods presented, as all options granted under these plans had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net income and earnings per share if we had applied the fair value recognition provisions of SFAS 123, “Accounting for Stock-Based Compensation,” to stock-based employee compensation:

     Income Taxes: A consolidated tax return is filed for all eligible entities. In accordance with SFAS 109, deferred income taxes are computed using the liability method, which establishes a deferred tax asset or liability based on temporary differences between the tax basis of an asset or liability and the basis recorded in the financial statements.

     Recent Accounting Developments: In December 2004 the FASB issued a revised Statement 123 (SFAS 123R), “Accounting for Stock-Based Compensation” requiring public entities to measure the cost of employee services received in exchange for an award of equity instruments based on grant date fair value. The cost will be recognized over the period during which an employee is required to provide service in exchange for the award - usually the vesting period. The effective date for this statement has been established by the Securities and Exchange Commission (SEC) to be as of the first annual period that begins after June 15, 2005. We are evaluating the

impact of this new pronouncement and expect it to be comparable to the pro forma effects of applying the original SFAS 123 as detailed above.

     Reclassifications: Certain amounts in the 2004 consolidated financial statements have been reclassified to conform to the 2005 presentation. These changes had no impact on previously reported net income or shareholders’ equity.
