Credit Quality Indicators

Management analyzes the Company's loan portfolios by applying specific monitoring policies and procedures that vary according to the relative risk profile and other characteristics within the various loan portfolios. Loans within the commercial portfolio segment are classified as either pass or criticized. Criticized credits are those that have regulatory risk ratings of special mention, substandard or doubtful; classified credits are those that have regulatory risk ratings of substandard or doubtful. Special mention credits are potentially weak, as the borrower has begun to exhibit deteriorating trends, which, if not corrected, may jeopardize repayment of the loan and result in further downgrade. Substandard credits have well-defined weaknesses, which, if not corrected, could jeopardize the full satisfaction of the debt. A credit classified as doubtful has critical weaknesses that make full collection improbable on the basis of currently existing facts and conditions.

The following tables summarize the loans in the commercial portfolio segment monitored for credit quality based on regulatory risk ratings. The amounts presented reflect unpaid principal balances less charge-offs.

The Company monitors the credit quality of its consumer portfolio segment based primarily on payment status. The following tables summarize the loans in the consumer portfolio segment, which exclude $10 million and $11 million of loans covered by FDIC loss share agreements, at March 31, 2017 and December 31, 2016, respectively:



	March 31, 2017
(Dollars in millions)	Accrual		Nonaccrual		Total

Home equity and other consumer loans	3,494		29		3,523
Total consumer portfolio	$	33,245	$	200	$	33,445

The Company also monitors the credit quality for substantially all of its consumer portfolio segment using credit scores provided by FICO and refreshed LTV ratios. FICO credit scores are refreshed at least quarterly to monitor the quality of the portfolio. Refreshed LTV measures the principal balance of the loan as a percentage of the estimated current value of the property securing the loan. Home equity loans are evaluated using combined LTV, which measures the principal balance of the combined loans that have liens against the property (including unused credit lines for home equity products) as a percentage of the estimated current value of the property securing the loans. The LTV ratios are refreshed on a quarterly basis, using the most recent home pricing index data available for the property location.

The following tables summarize the loans in the consumer portfolio segment based on refreshed FICO scores and refreshed LTV ratios at March 31, 2017 and December 31, 2016. These tables exclude loans covered by FDIC loss share agreements, as discussed above. The amounts presented reflect unpaid principal balances less partial charge-offs.

Troubled Debt Restructurings

The following table provides a summary of the Company’s recorded investment in TDRs as of March 31, 2017 and December 31, 2016. The summary includes those TDRs that are on nonaccrual status and those that continue to accrue interest. The Company had $48 million and $59 million in commitments to lend additional funds to borrowers with loan modifications classified as TDRs as of March 31, 2017 and December 31, 2016, respectively.



(Dollars in millions)	March 31, 2017		December 31, 2016

Residential mortgage	234		239
Home equity and other consumer loans	29		30
Total consumer portfolio	263		269
Total restructured loans	$	637	$	599

For the first quarter of 2017, TDR modifications in the commercial portfolio segment were primarily composed of interest rate changes, maturity extensions, covenant waivers, conversions from revolving lines of credit to term loans, or some combination thereof. In the consumer portfolio segment, primarily all of the modifications were composed of interest rate reductions and maturity extensions. Charge-offs related to TDR modifications for the three months ended March 31, 2017 and March 31, 2016 were de minimis. For the commercial and consumer portfolio segments, the allowance for loan losses for TDRs is measured on an individual loan basis or in pools with similar risk characteristics.

The following tables provide the pre- and post-modification outstanding recorded investment amounts of TDRs as of the date of the restructuring that occurred during the three months ended March 31, 2017 and 2016:

The following tables provide the recorded investment amounts of TDRs at the date of default, for which there was a payment default during the three months ended March 31, 2017 and 2016, and where the default occurred within the first twelve months after modification into a TDR. A payment default is defined as the loan being 60 days or more past due.

For loans in the consumer portfolio in which impairment is measured using the present value of expected future cash flows discounted at the loan’s effective interest rate, historical payment defaults and the propensity to redefault are some of the factors considered when determining the allowance for loan losses.

Loan Impairment

Loans that are individually evaluated for impairment include larger nonaccruing loans within the commercial and industrial, construction, and commercial mortgage loan portfolios and loans modified in a TDR. The Company records an impairment allowance when the value of an impaired loan is less than the recorded investment in the loan.

The following tables show information about impaired loans by class as of March 31, 2017 and December 31, 2016:
