9. Fair Value Measurements

The following table presents information about the Company’s assets measured at fair value on a recurring basis as of September 30, 2012, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value.

Fair values determined by Level 1 inputs utilize quoted prices in active markets for identical assets and liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the hierarchy. In such cases, the fair value is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

The following table presents certain quantitative information about the significant unobservable input used in the fair value measurement for the contingent consideration liability measured at fair value on a recurring basis using significant unobservable inputs (Level 3):


Description	Valuation Techniques	Significant Unobservable Inputs		Range (Weighted Average)
Liabilities
Contingent consideration liability	Present value techniques		Revenue growth percentage		5% - 36%

An increase in the revenue growth percentage may result in a significantly higher estimated fair value of the contingent consideration liability. Alternatively, a decrease in the revenue growth percentage may result in a significantly lower estimated fair value of the contingent consideration liability.

Valuation methods for instruments measured at fair value on a recurring basis

The following methods and assumptions were used to estimate the fair value of each class of financial instruments measured on a recurring basis:

Securities Available for Sale and Investment Securities Fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities.

Trading Securities Fair values for trading securities (including financial futures), are based on quoted market prices where available. If quoted market prices are not available, fair values are based on quoted market prices for similar securities.

Company-owned Life Insurance Fair values are based on quoted market prices or dealer quotes with adjustments for dividends, capital gains, and administrative charges.

Deferred Compensation Fair values are based on quoted market prices or dealer quotes.

Contingent Consideration The fair value of contingent consideration liabilities are derived from a discounted cash flow model of future contingent payments. The valuation of these liabilities are estimated by a collaborative effort of the Company’s mergers and acquisitions group, business unit management, and the corporate accounting group. These groups report primarily to the Company’s Chief Financial Officer. These future contingent payments are calculated based on estimates of future income and expense from each acquisition. These estimated cash flows are projected by the business unit management and reviewed by the mergers and acquisitions group. To obtain a current valuation of these projected cash flows, an expected present value technique is utilized to calculate a discount rate. The cash flow projections and discount rates are reviewed quarterly and updated as market conditions necessitate. Potential valuation adjustments are made as future income and expense projections for each acquisition are made which affect the calculation of the related contingent consideration payment. These adjustments are recorded through noninterest income and expense.

Valuation methods for instruments measured at fair value on a nonrecurring basis

The following methods and assumptions were used to estimate the fair value of each class of financial instruments measured on a non-recurring basis:

Impaired loans While the overall loan portfolio is not carried at fair value, adjustments are recorded on certain loans to reflect partial write-downs that are based on the value of the underlying collateral. In determining the value of real estate collateral, the Director of Property Management, who reports to the Chief Risk Officer, obtains external appraisals. The external appraisals are generally based on recent sales of comparable properties which are then adjusted for the unique characteristics of the property being valued. Upon receiving the external appraisal, the Director of Property Management in collaboration with the Company’s credit department led by the Chief Credit Officer review the appraisal to determine if the appraisal is a reasonable basis for the value of the property based upon historical experience and detailed knowledge of the specific property and location. In the case of non-real estate collateral, reliance is placed on a variety of sources, including external estimates of value and judgments based on the experience and expertise of internal specialists within the Company’s property management group and the Company’s credit department. The valuation of the impaired loans is reviewed on a quarterly basis. Because many of these inputs are not observable, the measurements are classified as Level 3.

Other real estate owned Other real estate owned consists of loan collateral which has been repossessed through foreclosure. This collateral is comprised of commercial and residential real estate and other non-real estate property, including auto, recreational and marine vehicles. Other real estate owned is recorded as held for sale initially at the lower of the loan balance or fair value of the collateral. The initial valuation of the foreclosed property is obtained through an appraisal process similar to the process described in the impaired loans paragraph above. Subsequent to foreclosure, valuations are reviewed quarterly and updated periodically, and the assets may be marked down further, reflecting a new cost basis. Fair value measurements may be based upon appraisals or third-party price opinions and, accordingly, those measurements may be classified as Level 2. Other fair value measurements may be based on internally developed pricing methods, and those measurements may be classified as Level 3.

Fair value disclosures require disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. The estimated fair value of the Company’s financial instruments at September 30, 2012 and December 31, 2011 are as follows (in millions):

The fair values of cash and short-term investments, demand and savings deposits, federal funds and repurchase agreements, and short-term debt approximate the carrying values.

Securities Held to Maturity Fair value of held-to-maturity securities are estimated by discounting the future cash flows using the current rates at which similar investments would be made to borrowers with similar credit ratings and for the same remaining maturities.

Federal Reserve Bank and Other Stock Amount consists of Federal Reserve Bank stock held by the Company’s affiliate banks and other miscellaneous investments. The fair value is considered to be the carrying value because no readily determinable market exists for these investments.

Loans Fair values are estimated for portfolios with similar financial characteristics. Loans are segregated by type, such as commercial, real estate, consumer, and credit card. Each loan category is further segmented into fixed and variable interest rate categories. The fair value of loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Time Deposits The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using the rates that are currently offered for deposits of similar remaining maturities.

Long-Term Debt Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate fair value of existing debt.

Other Off-Balance Sheet Instruments The fair value of loan commitments and letters of credit are determined based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and the present creditworthiness of the counterparties. Neither the fees earned during the year on these instruments nor their fair value at year-end are significant to the Company’s consolidated financial position.

The fair value estimates presented herein are based on pertinent information available to management as of September 30, 2012 and December 31, 2011. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these consolidated financial statements since those dates and, therefore, current estimates of fair value may differ significantly from the amount presented herein.

In the previously filed Form 10-Q for the period ended September 30, 2011, the Company inadvertently excluded certain disclosures regarding the fair value of the contingent consideration liability from this footnote as required by ASC 820, Fair Value Measurements and Disclosures. As a result, the accompanying 2011 fair value footnote has been amended to include the appropriate disclosures. There is no quantitative impact on the financial statements of the Company as a result of this additional disclosure.
