Organization, Consolidation and Presentation of Financial Statements [Abstract]

Debt Securities, Allowance for Credit Losses, Policy or Methodology Chage

Allowance for Credit Losses - Available-for-Sale Securities: For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. For available-for-sale debt securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income.

Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management believes the uncollectibility of an available-for-sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met.

Purchased Credit Deteriorated Loans, Allowance for Credit Losses, Policy or Methodology Change

Purchased Credit Deteriorated ("PCD") Loans: The Company has purchased loans during its acquisitions, some of which have experienced more than insignificant credit deterioration since origination. PCD loans are recorded at the amount paid. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan's purchase price and the allowance for credit losses becomes the initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is accreted or amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense.

Financing Receivable, Allowance for Credit Losses, Policy or Methodology Change

Allowance for Credit Losses - Loans: The allowance for credit losses is a valuation account that is deducted from the loans' amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes the uncollectibility of a loan balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics, such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environmental conditions, such as changes in unemployment rates, property values, or other relevant factors. The Company has identified the following portfolio segments and measures the allowance for credit losses using the following methods:

Portfolio Segment	Measurement Method
Commercial and industrial	Migration
Commercial real estate:
1-4 family	Migration
Hotels	Migration
Multi-family	Migration
Non Residential Non-Owner Occupied	Migration
Non Residential Owner Occupied	Migration
Residential real estate	Vintage
Home equity	Vintage
Consumer	Vintage

Migration is an analysis that tracks a closed pool of loans for a configurable period of time and calculates a loss ratio on only those loans in the pool at the start date based on outstanding balance. Vintage is a predictive loss model that includes a reasonable approximation of probable and estimable future losses by tracking each loan's net losses over the life of the loan as compared to its original balance. For demand deposit overdrafts, the allowance for credit losses is measured using the historical loss rate. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not included in the collective evaluation. When management determines that foreclosure is probable, the expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate.

Expected credit losses are estimated over the contractual term of the loan, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled-debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company.

Troubled Debt Restructuring

Troubled Debt Restructurings ("TDRs"): A loan for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, is considered to be a TDR. The allowance for credit loss on a TDR is measured using the same method as all other loans held for investment, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the allowance for credit loss is determined by discounting the expected future cash flows at the original interest rate of the loan.
