[1] Adjustment reflects opening fair value of securities portfolio, which was established as the new book basis of the portfolio.

[2] Adjustment reflect the reclassification of the fair value of certain loans identified by management as being held for sale at acquisition.

[3] Adjustments reflect changes to acquisition date fair values of certain assets based on additional information received post-acquisition within the measurement period. Measurement period adjustments included tax-effected adjustments to reduce the estimated fair value of a non-marketable investment, to reduce the fair value of certain distressed loans held for sale, and to increase the fair value of a bank-owned office.

[4] Adjustment reflects the estimated lifetime credit losses on the loan portfolio, the present value of the differences between contractual interest rates and market interest rates, and a reclassification of certain loans that were identified as held for sale at acquisition.

[5] Adjustment reflects fair value adjustments on certain acquired branch offices as well as certain software and computer equipment.

[6] Adjustment reflects the write down of certain foreclosed assets based on current estimates of property values given current market conditions and additional discounts based on the Company's planned disposition strategy.

[7] Adjustment reflects the tax impact of acquisition accounting fair value adjustments.

[8] Adjustment reflects the fair value of the acquired core deposit intangible.

[9] Adjustment reflects the impact of fair value adjustments on other assets, which include the write down of certain unusable prepaid expenses and the elimination of accrued interest on purchased credit-impaired loans.

[10] Adjustment reflects the fair value premium on time deposits, which was calculated by discounting future contractual interest payments at a current market interest rate.

[11] Adjustment reflects the fair value premium on FHLB advances, which was calculated by discounting future contractual interest payments at a current market interest rate. This fair value premium is also consistent with the prepayment penalty the FHLB would charge to terminate the advance.

[12] Adjustment reflects the impact of fair value adjustments on other liabilities, which primarily includes the accrual of a preferred stock dividend at acquisition.

[13] Amount reflects the adjustment to record other equity interests at fair value. The fair value of preferred stock issued to Treasury was estimated using by discounting future contractual dividend payments at a current market interest rate for preferred stocks of issuers with similar risk. The assumed liquidation date of the preferred stock was February 15, 2014, which is the date the dividend resets from 5 to 9 percent. The fair value of the common stock warrant issued to Treasury was estimated using a Black Scholes option pricing model assuming a warrant life through the dividend reset date.
