## CRITICAL ACCOUNTING POLICIES 

The Bancorp’s Consolidated Financial Statements are prepared in accordance with U.S. GAAP. Certain accounting policies require management to exercise judgment in determining methodologies, economic assumptions and estimates that may materially affect the value of the Bancorp’s assets or liabilities and results of operations and cash flows. The Bancorp's critical accounting policies include the accounting for the ALLL, reserve for unfunded commitments, income taxes, valuation of servicing rights, fair value measurements and goodwill. No material changes were made to the valuation techniques or models described below during the year ended December 31, 2010. 

## ALLL 

The Bancorp disaggregates its portfolio loans and leases into portfolio segments for purposes of determining the ALLL. The Bancorp’s portfolio segments include commercial, residential mortgage, and consumer. The Bancorp further disaggregates its portfolio segments into classes for purposes of monitoring and assessing credit quality based on certain risk characteristics. Classes within the commercial portfolio segment include commercial & industrial, commercial mortgage owner-occupied, commercial mortgage nonowner-occupied, commercial construction, and commercial leasing. The residential mortgage portfolio segment is also considered a class. Classes within the consumer segment include home equity, automobile, credit card, and other consumer loans and leases. For an analysis of the Bancorp’s ALLL by portfolio segment and credit quality information by class, see Note 7 of the Notes to Consolidated Financial Statements. 

Larger commercial loans included within aggregate borrower relationship balances exceeding $1 million that exhibit probable or observed credit weaknesses, as well as loans that have been modified in a TDR, are subject to individual review for impairment. The Bancorp considers the current value of collateral, credit quality of any guarantees, the loan structure, and other factors when evaluating whether an individual loan is impaired. Other factors may include the industry of the borrower, size and financial condition of the borrower, cash flow, leverage of the borrower, and the Bancorp’s evaluation of the borrower’s management. When individual loans are impaired, allowances are determined based on management’s estimate of the borrower’s ability to repay the loan given the availability of collateral, other sources of cash flow, as well as evaluation of legal options available to the Bancorp. Allowances for impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, fair value of the underlying collateral or readily observable secondary market values. The Bancorp evaluates the collectability of both principal and interest when assessing the need for a loss accrual. 

Historical credit loss rates are applied to commercial loans that are not impaired or are impaired, but smaller than the established threshold of $1 million and thus not subject to specific allowance allocations. The loss rates are derived from a migration analysis, which tracks the historical net charge-off experience sustained on loans according to their internal risk grade. The risk grading system currently utilized for allowance analysis purposes encompasses ten categories. 

Homogenous loans and leases in the residential mortgage and consumer portfolio segments are not individually risk graded. Rather, standard credit scoring systems and delinquency monitoring are used to assess credit risks, and allowances are established based on the expected net charge-offs. Loss rates are based on the average net charge-off history by loan category. Historical loss rates may be adjusted for significant factors that, in management’s judgment, are necessary to reflect losses inherent in 

the portfolio. Factors that management considers in the analysis include the effects of the national and local economies; trends in the nature and volume of delinquencies, charge-offs and nonaccrual loans; changes in loan mix; credit score migration comparisons; asset quality trends; risk management and loan administration; changes in the internal lending policies and credit standards; collection practices; and examination results from bank regulatory agencies and the Bancorp’s internal credit reviewers. 

The Bancorp’s current methodology for determining the ALLL is based on historical loss rates, current credit grades, specific allocation on TDRs and impaired commercial credits above specified thresholds and other qualitative adjustments. Allowances on individual commercial loans and historical loss rates are reviewed quarterly and adjusted as necessary based on changing borrower and/or collateral conditions and actual collection and charge-off experience. An unallocated allowance is maintained to recognize the imprecision in estimating and measuring losses when evaluating allowances for individual loans or pools of loans. 

Loans acquired by the Bancorp through a purchase business combination are recorded at fair value as of the acquisition date. The Bancorp does not carry over the acquired company’s ALLL, nor does the Bancorp add to its existing ALLL as part of purchase accounting. 

The Bancorp’s primary market areas for lending are the Midwestern and Southeastern regions of the United States. When evaluating the adequacy of allowances, consideration is given to these regional geographic concentrations and the closely associated effect changing economic conditions have on the Bancorp’s customers. 

## Reserve for Unfunded Commitments 

The reserve for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to unfunded credit facilities and is included in other liabilities in the Consolidated Balance Sheets. The determination of the adequacy of the reserve is based upon an evaluation of the unfunded credit facilities, including an assessment of historical commitment utilization experience, credit risk grading and historical loss rates based on credit grade migration. Net adjustments to the reserve for unfunded commitments are included in other noninterest expense in the Consolidated Statements of Income. 

## Income Taxes 

The Bancorp estimates income tax expense based on amounts expected to be owed to the various tax jurisdictions in which the Bancorp conducts business. On a quarterly basis, management assesses the reasonableness of its effective tax rate based upon its current estimate of the amount and components of net income, tax credits and the applicable statutory tax rates expected for the full year. The estimated income tax expense is recorded in the Consolidated Statements of Income. 

Deferred income tax assets and liabilities are determined using the balance sheet method and are reported in other assets and accrued taxes, interest and expenses, respectively in the Consolidated Balance Sheets. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities, and recognizes enacted changes in tax rates and laws. Deferred tax assets are recognized to the extent they exist and are subject to a valuation allowance based on management’s judgment that realization is more-likely-than-not. This analysis is performed on a quarterly basis and includes an evaluation of all positive and negative evidence to determine whether realization is more-likely- than-not.
