Past Due and Non-accrual Loans

Allowance for Credit Losses

The Company maintains an allowance for credit losses at a level deemed adequate by management to absorb probable losses inherent in the loan portfolio. Refer to Note 1, “Summary of Significant Accounting Policies,” for the accounting policy for the allowance for credit losses.

Impaired Loans

A portion of the Company’s allowance for credit losses is allocated to impaired loans. Impaired loans consist of corporate non-accrual loans and TDRs. Smaller homogeneous loans, such as home equity, installment, and 1-4 family mortgages, are not individually assessed for impairment.

Impaired Loans

(Dollar amounts in thousands)

	June 30, 2012		December 31, 2011
Impaired loans individually evaluated for impairment:
Impaired loans with a related allowance for credit losses (1)	$	102,475	$	76,397
Impaired loans with no specific related allowance for credit losses (2)		62,617		83,090
Total impaired loans individually evaluated for impairment		168,092		159,487
Corporate non-accrual loans not individually evaluated for impairment (3)		17,704		15,084
Total corporate non-accrual loans		185,796		174,571
TDRs, still accruing interest		7,811		17,864
Total impaired loans	$	193,607	$	192,435
Valuation allowance related to impaired loans	$	25,267	$	26,095

(1)	These impaired loans require a valuation allowance because the present value of expected future cash flows or the estimated value of the related collateral, less estimated selling costs, is less than the recorded investment in the loans.
(2)	No specific allowance for credit losses is allocated to these loans since they are deemed to be sufficiently collateralized or had charge-offs.
(3)	These are loans with balances under a specified threshold.

The table below provides a breakdown of loans and the related allowance for credit losses by portfolio segment. Loans individually evaluated for impairment include corporate non-accrual loans with the exception of certain loans with balances under a specified threshold.

The present value of any decreases in expected cash flows of covered loans after the purchase date is recognized by recording a charge-off through the allowance for loan losses. Since most covered loans are accounted for as purchased impaired loans and the carrying values of those loans are periodically adjusted for any changes in expected future cash flows, they are not included in the calculation of the allowance for credit losses and are not displayed in this table except for open-end consumer loans.

TDRs

Loan modifications are generally performed at the request of the individual borrower and may include forgiveness of principal, reduction in interest rates, changes in payments, and maturity date extensions. A discussion of our accounting policies for TDRs is contained in Note 1, “Summary of Significant Accounting Policies.”

The specific reserve portion of the allowance for loan losses on TDRs for all segments of loans is determined by estimating the value of the loan. This is determined by discounting the restructured cash flows at the original effective rate of the loan before modification or is based on the fair value of the underlying collateral, less costs to sell, if repayment of the loan is collateral-dependent. If the resulting amount is less than the recorded book value, the Company either establishes a valuation allowance (i.e., specific reserve) as a component of the allowance for loan losses or charges off the impaired balance if it determines that it is a confirmed loss. TDRs had related valuation allowances totaling $1.2 million as of June 30, 2012 and $94,000 as of December 31, 2011.

The allowance for loan losses also includes an allowance based on a loss migration analysis for each loan category for loans that are not individually evaluated for impairment. All loans charged-off, including TDRs charged-off, are factored into this calculation by portfolio segment.

TDRs that have payment defaults and do not perform in accordance with the modified terms are transferred to non-accrual. The following table presents TDRs that had payment defaults during the quarters ended June 30, 2012 and June 30, 2011 where the default occurred within twelve months of the restructured date.

Credit Quality Indicators

Corporate loans and commitments are assessed for risk and assigned ratings based on various characteristics, such as the borrower’s cash flow, leverage, collateral, management characteristics, and other factors. Ratings for commercial credits are reviewed periodically. On a quarterly basis, consumer loans are assessed for credit quality based on the delinquency status of the loan.

(1)	Loans categorized as special mention exhibit potential weaknesses that require the close attention of management since these potential weaknesses may result in the deterioration of repayment prospects at some future date.
(2)	Loans categorized as substandard continue to accrue interest, but exhibit a well-defined weakness or weaknesses that may jeopardize the liquidation of the debt. The loans continue to accrue interest because they are well secured and collection of principal and interest is expected within a reasonable time.
(3)	Loans categorized as non-accrual exhibit a well-defined weakness or weaknesses that may jeopardize the liquidation of the debt and are characterized by the distinct possibility that the Company could sustain some loss if the deficiencies are not corrected. These loans were placed on non-accrual status.
