The Company had loans of $83.9 billion at March 31, 2018, and $83.3 billion at December 31, 2017, pledged at the Federal Home Loan Bank, and loans of $68.4 billion at March 31, 2018, and $68.0 billion at December 31, 2017, pledged at the Federal Reserve Bank. Originated loans are reported at the principal amount outstanding, net of unearned interest and deferred fees and costs, and any partial charge-offs recorded. Net unearned interest and deferred fees and costs amounted to $826 million at March 31, 2018 and $830 million at December 31, 2017. All purchased loans and related indemnification assets are recorded at fair value at the date of purchase. The Company evaluates purchased loans for impairment at the date of purchase in accordance with applicable authoritative accounting guidance. Purchased loans with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are considered “purchased impaired loans.” All other purchased loans are considered “purchased nonimpaired loans.” Changes in the accretable balance for purchased impaired loans were as follows: Three Months Ended March 31 (Dollars in Millions) 2018 2017 Balance at beginning of period $ 350 $ 698 Accretion (91 ) (90 ) Disposals (12 ) (23 ) Reclassifications from nonaccretable difference (a) 10 53 Other – (1 ) Balance at end of period $ 257 $ 637 (a) Primarily relates to changes in expected credit performance. Allowance for Credit Losses The allowance for credit losses is established for probable and estimable losses incurred in the Company’s loan and lease portfolio, including unfunded credit commitments, and includes certain amounts that do not represent loss exposure to the Company because those losses are recoverable under loss sharing agreements with the Federal Deposit Insurance Corporation (“FDIC”). The allowance for credit losses is increased through provisions charged to earnings and reduced by net charge-offs. Management evaluates the adequacy of the allowance for incurred losses on a quarterly basis. The allowance recorded for loans in the commercial lending segment is based on reviews of individual credit relationships and considers the migration analysis of commercial lending segment loans and actual loss experience. For each loan type, this historical loss experience is adjusted as necessary to consider any relevant changes in portfolio composition, lending policies, underwriting standards, risk management practices or economic conditions. The results of the analysis are evaluated quarterly to confirm the selected loss experience is appropriate for each commercial loan type. The allowance recorded for impaired loans greater than $5 million in the commercial lending segment is based on an individual loan analysis utilizing expected cash flows discounted using the original effective interest rate, the observable market price of the loan, or the fair value of the collateral, less selling costs, for collateral-dependent loans, rather than the migration analysis. The allowance recorded for all other commercial lending segment loans is determined on a homogenous pool basis and includes consideration of product mix, risk characteristics of the portfolio, delinquency status, bankruptcy experience, portfolio growth and historical losses, adjusted for current trends. The Company also considers the impacts of any loan modifications made to commercial lending segment loans and any subsequent payment defaults to its expectations of cash flows, principal balance, and current expectations about the borrower’s ability to pay in determining the allowance for credit losses. The allowance recorded for Troubled Debt Restructuring (“TDR”) loans and purchased impaired loans in the consumer lending segment is determined on a homogenous pool basis utilizing expected cash flows discounted using the original effective interest rate of the pool, or the prior quarter effective rate, respectively. The allowance for collateral-dependent loans in the consumer lending segment is determined based on the fair value of the collateral less costs to sell. The allowance recorded for all other consumer lending segment loans is determined on a homogenous pool basis and includes consideration of product mix, risk characteristics of the portfolio, bankruptcy experience, delinquency status, refreshed loan-to-value The allowance for the covered loan segment is evaluated each quarter in a manner similar to that described for non-covered In addition, subsequent payment defaults on loan modifications considered TDRs are considered in the underlying factors used in the determination of the appropriateness of the allowance for credit losses. For each loan segment, the Company estimates future loan charge-offs through a variety of analysis, trends and underlying assumptions. With respect to the commercial lending segment, TDRs may be collectively evaluated for impairment where observed performance history, including defaults, is a primary driver of the loss allocation. For commercial TDRs individually evaluated for impairment, attributes of the borrower are the primary factors in determining the allowance for credit losses. However, historical loss experience is also incorporated into the allowance methodology applied to this category of loans. With respect to the consumer lending segment, performance of the portfolio, including defaults on TDRs, is considered when estimating future cash flows. The Company’s methodology for determining the appropriate allowance for credit losses for each loan segment also considers the imprecision inherent in the methodologies used. As a result, in addition to the amounts determined under the methodologies described above, management also considers the potential impact of other qualitative factors which include, but are not limited to, economic factors; geographic and other concentration risks; delinquency and nonaccrual trends; current business conditions; changes in lending policy, underwriting standards and other relevant business practices; results of internal review; and the regulatory environment. The consideration of these items results in adjustments to allowance amounts included in the Company’s allowance for credit losses for each of the above loan segments.

(b) Includes expected reimbursements from the FDIC under loss sharing agreements. Credit Quality The credit quality of the Company’s loan portfolios is assessed as a function of net credit losses, levels of nonperforming assets and delinquencies, and credit quality ratings as defined by the Company. For all loan classes, loans are considered past due based on the number of days delinquent except for monthly amortizing loans which are classified delinquent based upon the number of contractually required payments not made (for example, two missed payments is considered 30 days delinquent). When a loan is placed on nonaccrual status, unpaid accrued interest is reversed, reducing interest income in the current period. Commercial lending segment loans are generally placed on nonaccrual status when the collection of principal and interest has become 90 days past due or is otherwise considered doubtful. Commercial lending segment loans are generally fully or partially charged down to the fair value of the collateral securing the loan, less costs to sell, when the loan is placed on nonaccrual. Consumer lending segment loans are generally charged-off 1-4 charge-off 1-4 family charged-off. charged-off 1-4 charged-off charged-off charge-off. For all loan classes, interest payments received on nonaccrual loans are generally recorded as a reduction to a loan’s carrying amount while a loan is on nonaccrual and are recognized as interest income upon payoff of the loan. However, interest income may be recognized for interest payments if the remaining carrying amount of the loan is believed to be collectible. In certain circumstances, loans in any class may be restored to accrual status, such as when a loan has demonstrated sustained repayment performance or no amounts are past due and prospects for future payment are no longer in doubt; or when the loan becomes well secured and is in the process of collection. Loans where there has been a partial charge-off charged-off) Covered loans not considered to be purchased impaired are evaluated for delinquency, nonaccrual status and charge-off The following table provides a summary of loans by portfolio class, including the delinquency status of those that continue to accrue interest, and those that are nonperforming: Accruing (Dollars in Millions) Current 30-89 Days 90 Days or Nonperforming Total March 31, 2018 Commercial $ 97,494 $ 241 $ 61 $ 301 $ 98,097 Commercial real estate 39,979 38 4 119 40,140 Residential mortgages (a) 59,769 146 132 430 60,477 Credit card 20,356 275 270 – 20,901 Other retail 54,730 320 99 168 55,317 Total loans, excluding covered loans 272,328 1,020 566 1,018 274,932 Covered loans 2,790 47 136 6 2,979 Total loans $ 275,118 $ 1,067 $ 702 $ 1,024 $ 277,911 December 31, 2017 Commercial $ 97,005 $ 250 $ 57 $ 249 $ 97,561 Commercial real estate 40,279 36 6 142 40,463 Residential mortgages (a) 59,013 198 130 442 59,783 Credit card 21,593 302 284 1 22,180 Other retail 56,685 376 95 168 57,324 Total loans, excluding covered loans 274,575 1,162 572 1,002 277,311 Covered loans 2,917 50 148 6 3,121 Total loans $ 277,492 $ 1,212 $ 720 $ 1,008 $ 280,432 (a) At March 31, 2018, $376 million of loans 30–89 days past due and $1.9 billion of loans 90 days or more past due purchased from Government National Mortgage Association (“GNMA”) mortgage pools whose repayments are insured by the Federal Housing Administration or guaranteed by the United States Department of Veterans Affairs, were classified as current, compared with $385 million and $1.9 billion at December 31, 2017, respectively. At March 31, 2018, the amount of foreclosed residential real estate held by the Company, and included in OREO, was $138 million ($118 million excluding covered assets), compared with $156 million ($135 million excluding covered assets) at December 31, 2017. These amounts exclude $243 million and $267 million at March 31, 2018 and December 31, 2017, respectively, of foreclosed residential real estate related to mortgage loans whose payments are primarily insured by the Federal Housing Administration or guaranteed by the United States Department of Veterans Affairs. In addition, the amount of residential mortgage loans secured by residential real estate in the process of foreclosure at March 31, 2018 and December 31, 2017, was $1.7 billion, of which $1.3 billion related to loans purchased from Government National Mortgage Association (“GNMA”) mortgage pools whose repayments are insured by the Federal Housing Administration or guaranteed by the United States Department of Veterans Affairs. The Company classifies its loan portfolios using internal credit quality ratings on a quarterly basis. These ratings include pass, special mention and classified, and are an important part of the Company’s overall credit risk management process and evaluation of the allowance for credit losses. Loans with a pass rating represent those loans not classified on the Company’s rating scale for problem credits, as minimal credit risk has been identified. Special mention loans are those loans that have a potential weakness deserving management’s close attention. Classified loans are those loans where a well-defined weakness has been identified that may put full collection of contractual cash flows at risk. It is possible that others, given the same information, may reach different reasonable conclusions regarding the credit quality rating classification of specific loans.

For all loan classes, a loan is considered to be impaired when, based on current events or information, it is probable the Company will be unable to collect all amounts due per the contractual terms of the loan agreement. Impaired loans include all nonaccrual and TDR loans. For all loan classes, interest income on TDR loans is recognized under the modified terms and conditions if the borrower has demonstrated repayment performance at a level commensurate with the modified terms over several payment cycles. Interest income is generally not recognized on other impaired loans until the loan is paid off. However, interest income may be recognized for interest payments if the remaining carrying amount of the loan is believed to be collectible. Factors used by the Company in determining whether all principal and interest payments due on commercial and commercial real estate loans will be collected and, therefore, whether those loans are impaired include, but are not limited to, the financial condition of the borrower, collateral and/or guarantees on the loan, and the borrower’s estimated future ability to pay based on industry, geographic location and certain financial ratios. The evaluation of impairment on residential mortgages, credit card loans and other retail loans is primarily driven by delinquency status of individual loans or whether a loan has been modified, and considers any government guarantee where applicable. Individual covered loans, whose future losses are covered by loss sharing agreements with the FDIC that substantially reduce the risk of credit losses to the Company, are evaluated for impairment and accounted for in a manner consistent with the class of loan they would have been included in had the loss sharing coverage not been in place. A summary of impaired loans, which include all nonaccrual and TDR loans, by portfolio class was as follows: (Dollars in Millions) Period-end Unpaid Valuation Commitments March 31, 2018 Commercial $ 540 $ 833 $ 42 $ 214 Commercial real estate 254 573 9 – Residential mortgages 1,881 2,118 109 1 Credit card 234 234 60 – Other retail 299 383 19 4 Total loans, excluding GNMA and covered loans 3,208 4,141 239 219 Loans purchased from GNMA mortgage pools 1,566 1,566 30 – Covered loans 38 46 1 – Total $ 4,812 $ 5,753 $ 270 $ 219 December 31, 2017 Commercial $ 550 $ 915 $ 44 $ 199 Commercial real estate 280 596 11 – Residential mortgages 1,946 2,339 116 1 Credit card 230 230 60 – Other retail 302 400 22 4 Total loans, excluding GNMA and covered loans 3,308 4,480 253 204 Loans purchased from GNMA mortgage pools 1,681 1,681 25 – Covered loans 38 44 1 – Total $ 5,027 $ 6,205 $ 279 $ 204 (a) Substantially all loans classified as impaired at March 31, 2018 and December 31, 2017, had an associated allowance for credit losses.

Concessionary modifications are classified as TDRs unless the modification results in only an insignificant delay in payments to be received. The Company recognizes interest on TDRs if the borrower complies with the revised terms and conditions as agreed upon with the Company and has demonstrated repayment performance at a level commensurate with the modified terms over several payment cycles, which is generally six months or greater. To the extent a previous restructuring was insignificant, the Company considers the cumulative effect of past restructurings related to the receivable when determining whether a current restructuring is a TDR. Loans classified as TDRs are considered impaired loans for reporting and measurement purposes. The following table provides a summary of loans modified as TDRs during the periods presented by portfolio class: 2018 2017 Three Months Ended March 31 (Dollars in Millions) Number Pre-Modification Post-Modification Number Pre-Modification Post-Modification Commercial 623 $ 81 $ 75 830 $ 137 $ 128 Commercial real estate 29 16 16 23 9 8 Residential mortgages 148 17 16 356 40 41 Credit card 8,546 43 43 9,405 45 46 Other retail 559 11 10 622 11 9 Total loans, excluding GNMA and covered loans 9,905 168 160 11,236 242 232 Loans purchased from GNMA mortgage pools 888 117 113 2,929 387 378 Covered loans – – – 4 1 1 Total loans 10,793 $ 285 $ 273 14,169 $ 630 $ 611 Residential mortgages, home equity and second mortgages, and loans purchased from GNMA mortgage pools in the table above include trial period arrangements offered to customers during the periods presented. The post-modification balances for these loans reflect the current outstanding balance until a permanent modification is made. In addition, the post-modification balances typically include capitalization of unpaid accrued interest and/or fees under the various modification programs. For those loans modified as TDRs during the first quarter of 2018, at March 31, 2018, 50 residential mortgages, 31 home equity and second mortgage loans and 781 loans purchased from GNMA mortgage pools with outstanding balances of $8 million, $3 million and $105 million, respectively, were in a trial period and have estimated post-modification balances of $8 million, $3 million and $101 million, respectively, assuming permanent modification occurs at the end of the trial period. The Company has implemented certain restructuring programs that may result in TDRs. However, many of the Company’s TDRs are also determined on a case-by-case For the commercial lending segment, modifications generally result in the Company working with borrowers on a case-by-case Modifications for the consumer lending segment are generally part of programs the Company has initiated. The Company modifies residential mortgage loans under Federal Housing Administration, United States Department of Veterans Affairs, or its own internal programs. Under these programs, the Company offers qualifying homeowners the opportunity to permanently modify their loan and achieve more affordable monthly payments by providing loan concessions. These concessions may include adjustments to interest rates, conversion of adjustable rates to fixed rates, extension of maturity dates or deferrals of payments, capitalization of accrued interest and/or outstanding advances, or in limited situations, partial forgiveness of loan principal. In most instances, participation in residential mortgage loan restructuring programs requires the customer to complete a short-term trial period. A permanent loan modification is contingent on the customer successfully completing the trial period arrangement, and the loan documents are not modified until that time. The Company reports loans in a trial period arrangement as TDRs and continues to report them as TDRs after the trial period. Credit card and other retail loan TDRs are generally part of distinct restructuring programs providing customers experiencing financial difficulty with modifications whereby balances may be amortized up to 60 months, and generally include waiver of fees and reduced interest rates. In addition, the Company considers secured loans to consumer borrowers that have debt discharged through bankruptcy where the borrower has not reaffirmed the debt to be TDRs.

(b) Represents decreases in expected reimbursements by the FDIC as a result of decreases in expected losses on the covered loans. These amounts are amortized as a reduction in interest income on covered loans over the shorter of the expected life of the respective covered loans or the remaining contractual term of the indemnification agreements. Interest income is recognized on purchased impaired loans through accretion of the difference between the carrying amount of those loans and their expected cash flows. The initial determination of the fair value of the purchased loans includes the impact of expected credit losses and, therefore, no allowance for credit losses is recorded at the purchase date. To the extent credit deterioration occurs after the date of acquisition, the Company records an allowance for credit losses. |
