| Goodwill     | Note 4. GoodwillDuring 2009,the impact of deteriorating economic conditions had significantlyimpacted the banking industry and the financial results of theCorporation.  As a result, while only required to testgoodwill annually, the Corporation decided to test its goodwill forimpairment on three separate occasions during 2009. In 2010, theCorporation returned to its annual testing of goodwill forimpairment, most recently as of November 30, 2010.TheCorporation used an independent, outside firm to help determine thefair value of the Corporation for purposes of the first step of theimpairment test.  The Discounted Earnings method (anIncome Approach) as well as the Guideline Publicly Traded CompanyMethod and the Transaction Method (both Market Approaches thatapply market multiples to various financial metrics to derivevalue) were used and weighted to form the conclusion of fairvalue.  The Discounted Earnings method was given primaryweight in the fair value analysis.TheDiscounted Earnings method was based primarily on: 1) managementprojections derived from expected balance sheet and incomestatement assumptions, based on current economic conditions, whichcontinue to show signs of stabilization from 2009, improvements in2010 and continued improvements going forward; 2) present valuefactors based on an implied market cost of equity, and 3) historic(long-term) price-to-earnings multiples for comparablecompanies.  Determining the Corporation’s fairvalue using the Discounted Earnings method involves a significantamount of judgment.  The methodology is largely based onunobservable level three inputs.  The test results aredependent upon attaining actual financial results consistent withthe forecasts and assumptions used in the valuationmodel.  The Discounted Earnings method relied on aterminal Price/Earnings (“P/E”) multiple. The P/Emultiple used to determine terminal value was notably lower thanthe historic P/E multiple observed for the Corporation, the peergroup, and the NASDAQ community banking index (ABAQ). Based on theresults of the step one analysis, the fair value exceeded theCorporation’s carrying value; therefore, it was concludedgoodwill is not impaired.Additionally,a sensitivity analysis was performed on the Discounted Earningsmethodology by testing a range of the following metrics: 1) impliedmarket cost of equity; and 2) historic (long-term)price-to-earnings multiples for comparablecompanies.  Based on the sensitivity testing, at thelow-end of the sensitivity test range (for both metrics), the fairvalue of the Corporation exceeded its carrying value. For reasonsthat include but are not limited to the aforementioned, managementbelieves the Corporation’s recently traded stock price is notindicative of fair value. |
