CREDIT RISK PROFILE
Commercial Portfolio Segment
For purposes of monitoring the credit quality and risk characteristics of its commercial portfolio segment, the Bancorp disaggregates the segment into the following classes: commercial and industrial, commercial mortgage owner-occupied, commercial mortgage nonowner-occupied, commercial construction and commercial leases.

To facilitate the monitoring of credit quality within the commercial portfolio segment, the Bancorp utilizes the following categories of credit grades: pass, special mention, substandard, doubtful and loss. The five categories, which are derived from standard regulatory rating definitions, are assigned upon initial approval of credit to borrowers and updated periodically thereafter.

Pass ratings, which are assigned to those borrowers that do not have identified potential or well-defined weaknesses and for which there is a high likelihood of orderly repayment, are updated at least annually based on the size and credit characteristics of the borrower. All other categories are updated on a quarterly basis during the month preceding the end of the calendar quarter.

The Bancorp assigns a special mention rating to loans and leases that have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may, at some future date, result in the deterioration of the repayment prospects for the loan or lease or the Bancorp’s credit position.

The Bancorp assigns a substandard rating to loans and leases that are inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged. Substandard loans and leases have well-defined weaknesses or weaknesses that could jeopardize the orderly repayment of the debt. Loans and leases in this grade also are characterized by the distinct possibility that the Bancorp will sustain some loss if the deficiencies noted are not addressed and corrected.

The Bancorp assigns a doubtful rating to loans and leases that have all the attributes of a substandard rating with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonable specific pending factors that may work to the advantage of and strengthen the credit quality of the loan or lease, its classification as an estimated loss is deferred until its more exact
status may be determined. Pending factors may include a proposed merger or acquisition, liquidation proceeding, capital injection, perfecting liens on additional collateral or refinancing plans.

Loans and leases classified as loss are considered uncollectible and are charged off in the period in which they are determined to be uncollectible. Because loans and leases in this category are fully charged off, they are not included in the following tables.

For loans and leases that are collectively evaluated, the Bancorp utilizes models to forecast expected credit losses over a reasonable and supportable forecast period based on the probability of a loan or lease defaulting, the expected balance at the estimated date of default and the expected loss percentage given a default. For the commercial portfolio segment, the estimates for probability of default are primarily based on internal ratings assigned to each commercial borrower on a 13-point scale and historical observations of how those ratings migrate to a default over time in the context of macroeconomic conditions. For loans with available credit, the estimate of the expected balance at the time of default considers expected utilization rates, which are primarily based on macroeconomic conditions and the utilization history of similar borrowers under those economic conditions. The estimates for loss severity are primarily based on collateral type and coverage levels and the susceptibility of those characteristics to changes in macroeconomic conditions. For more information about the Bancorp’s processes for developing these models, estimating credit losses for periods beyond the reasonable and supportable forecast period and for estimating credit losses for individually evaluated loans, refer to Note 1 of the Notes to Consolidated Financial Statements included in the Bancorp’s Annual Report on Form 10-K for the year ended December 31, 2020.

Residential Mortgage and Consumer Portfolio Segments
For purposes of monitoring the credit quality and risk characteristics of its consumer portfolio segment, the Bancorp disaggregates the segment into the following classes: home equity, indirect secured consumer loans, credit card and other consumer loans. The Bancorp’s residential mortgage portfolio segment is also a separate class.

The Bancorp considers repayment performance as the best indicator of credit quality for residential mortgage and consumer loans, which includes both the delinquency status and performing versus nonperforming status of the loans. The delinquency status of all residential mortgage and consumer loans and the performing versus nonperforming status is presented in the following table. Loans and leases which received payment deferrals or forbearances as part of the Bancorp’s COVID-19 customer relief programs are generally not reported as delinquent during the forbearance or deferral period if the loan or lease was less than 30 days past due at March 1, 2020 (the effective date of the COVID-19 national emergency declaration) unless the loan or lease subsequently becomes delinquent according to its modified terms. Refer to Note 1 of the Notes to Consolidated Financial Statements included in the Bancorp’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional information.

For collectively evaluated loans in the consumer and residential mortgage portfolio segments, the Bancorp’s expected credit loss models primarily utilize the borrower’s FICO score and delinquency history in combination with macroeconomic conditions when estimating the probability of default. The estimates for loss severity are primarily based on collateral type and coverage levels and the susceptibility of those characteristics to changes in macroeconomic conditions. The expected balance at the estimated date of default is also particularly significant for portfolio classes which generally have longer terms (such as residential mortgage loans and home equity) and portfolio classes containing a high concentration of loans with revolving privileges (such as home equity). The estimate of the expected balance at the time of default considers expected prepayment and utilization rates where applicable, which are primarily based on macroeconomic conditions and the utilization history of similar borrowers under those economic conditions. Refer to Note 1 of the Notes to Consolidated Financial Statements included in the Bancorp’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional information about the Bancorp’s process for developing these models and its process for estimating credit losses for periods beyond the reasonable and supportable forecast period.

(a)Information includes advances made pursuant to servicing agreements for GNMA mortgage pools whose repayments are insured by the FHA or guaranteed by the VA. As of December 31, 2020, $103 of these loans were 30-89 days past due and $242 were 90 days or more past due. The Bancorp recognized an immaterial amount and $2 of losses during the three and nine months ended September 30, 2020, respectively, due to claim denials and curtailments associated with these insured or guaranteed loans.
(b)Excludes $161 of residential mortgage loans measured at fair value at December 31, 2020.
Collateral-Dependent Loans and Leases
The Bancorp considers a loan or lease to be collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. When a loan or lease is collateral-dependent, its fair value is generally based on the fair value less cost to sell of the underlying collateral.

Troubled Debt Restructurings
A loan is accounted for as a TDR if the Bancorp, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider. TDRs include concessions granted under reorganization, arrangement or other provisions of the Federal Bankruptcy Act. Within each of the Bancorp’s loan classes, TDRs typically involve either a reduction of the stated interest rate of the loan, an extension of the loan’s maturity date with a stated rate lower than the current market rate for a new loan with similar risk, or in limited circumstances, a reduction of the principal balance of the loan or the loan’s accrued interest. Modifying the terms of a loan may result in an increase or decrease to the ALLL depending upon the terms modified, the method used to measure the ALLL for a loan prior to modification, the extent of collateral, and whether any charge-offs were recorded on the loan before or at the time of modification. Refer to the ALLL section of Note 1 of the Notes to Consolidated Financial Statements included in the Bancorp’s Annual Report on Form 10-K for the year ended December 31, 2020 for information on the Bancorp’s ALLL methodology. Upon modification of a loan, the Bancorp measures the expected credit loss as either the difference between the amortized cost of the loan and the fair value of collateral less cost to sell or the difference between the estimated future cash flows expected to be collected on the modified loan, discounted at the original effective yield of the loan, and the carrying value of the loan. The resulting measurement may result in the need for minimal or no allowance regardless of which is used because it is probable that all cash flows will be collected under the modified terms of the loan. In addition, if the stated interest rate was increased in a TDR that is not collateral-dependent, the cash flows on the modified loan, using the pre-modification interest rate as the discount rate, often exceed the amortized cost basis of the loan. Conversely, upon a modification that reduces the stated interest rate on a loan that is not collateral-dependent, the Bancorp recognizes an increase to the ALLL. If a TDR involves a reduction of the principal balance of the loan or the loan’s accrued interest, that amount is charged off to the ALLL. Loans discharged in a Chapter 7 bankruptcy and not reaffirmed by the borrower are treated as nonaccrual collateral-dependent loans with a charge-off recognized to reduce the carrying values of such loans to the fair value of the related collateral less costs to sell. Certain loan modifications which were made in response to the COVID-19 pandemic were not evaluated for classification as a TDR. Refer to the Regulatory Developments Related to the COVID-19 Pandemic section of Note 1 of the Notes to Consolidated Financial Statements included in the Bancorp’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional information.

The Bancorp had commitments to lend additional funds to borrowers whose terms have been modified in a TDR, consisting of line of credit and letter of credit commitments of $104 million and $64 million, respectively, as of September 30, 2021 compared to $67 million and $72 million, respectively, as of December 31, 2020.

The Bancorp considers TDRs that become 90 days or more past due under the modified terms as subsequently defaulted. For commercial loans not subject to individual evaluation for an ALLL, the applicable commercial models are applied for purposes of determining the ALLL as well as qualitatively assessing whether those loans are reasonably expected to be further restructured prior to their maturity date and, if so, the impact such a restructuring would have on the remaining contractual life of the loans. When a residential mortgage, home equity, indirect secured consumer or other consumer loan that has been modified in a TDR subsequently defaults, the present value of expected cash flows used in the measurement of the expected credit loss is generally limited to the expected net proceeds from the sale of the loan’s underlying collateral and any resulting collateral shortfall is reflected as a charge-off or an increase in ALLL. The Bancorp recognizes an ALLL for the entire balance of the credit card loans modified in a TDR that subsequently default.

The following tables provide a summary of TDRs that subsequently defaulted during the three months ended September 30, 2021 and 2020 and were within 12 months of the restructuring date:
