The Company had loans of $90.0 billion at June 30, 2018, and $83.3 billion at December 31, 2017, pledged at the Federal Home Loan Bank, and loans of $68.7 billion at June 30, 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 $823 million at June 30, 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 June 30 Six Months Ended June 30 (Dollars in Millions) 2018 2017 2018 2017 Balance at beginning of period $ 257 $ 637 $ 350 $ 698 Accretion (90 ) (89 ) (181 ) (179 ) Disposals (15 ) (28 ) (27 ) (51 ) Reclassifications from nonaccretable difference (a) 5 30 15 83 Other – (4 ) – (5 ) Balance at end of period $ 157 $ 546 $ 157 $ 546 (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 ratios when possible, portfolio growth and historical losses, adjusted for current trends. The Company also considers any modifications made to consumer lending segment loans including the impacts of any subsequent payment defaults since modification in determining the allowance for credit losses, such as the borrower’s ability to pay under the restructured terms, and the timing and amount of payments. The allowance for the covered loan segment is evaluated each quarter in a manner similar to that described for non-covered loans and reflects decreases in expected cash flows of those loans after the acquisition date. The provision for credit losses for covered loans considers the indemnification provided by the FDIC. 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. The Company also assesses the credit risk associated with off-balance sheet loan commitments, letters of credit, and derivatives. Credit risk associated with derivatives is reflected in the fair values recorded for those positions. The liability for off-balance sheet credit exposure related to loan commitments and other credit guarantees is included in other liabilities. Because business processes and credit risks associated with unfunded credit commitments are essentially the same as for loans, the Company utilizes similar processes to estimate its liability for unfunded credit commitments.

(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 at a specific number of days or payments past due. Residential mortgages and other retail loans secured by 1-4 family properties are generally charged down to the fair value of the collateral securing the loan, less costs to sell, at 180 days past due. Residential mortgage loans and lines in a first lien position are placed on nonaccrual status in instances where a partial charge-off occurs unless the loan is well secured and in the process of collection. Residential mortgage loans and lines in a junior lien position secured by 1-4 family 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 may be returned to accrual status if all principal and interest (including amounts previously charged-off) is expected to be collected and the loan is current. Covered loans not considered to be purchased impaired are evaluated for delinquency, nonaccrual status and charge-off consistent with the class of loan they would be included in had the loss share coverage not been in place. Generally, purchased impaired loans are considered accruing loans. However, the timing and amount of future cash flows for some loans is not reasonably estimable, and those loans are classified as nonaccrual loans with interest income not recognized until the timing and amount of the future cash flows can be reasonably estimated. 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 Past Due 90 Days or More Past Due Nonperforming Total June 30, 2018 Commercial $ 98,847 $ 228 $ 58 $ 224 $ 99,357 Commercial real estate 39,250 42 3 104 39,399 Residential mortgages (a) 60,636 160 113 400 61,309 Credit card 21,054 263 249 – 21,566 Other retail 55,134 320 91 178 55,723 Total loans, excluding covered loans 274,921 1,013 514 906 277,354 Covered loans 2,644 47 126 6 2,823 Total loans $ 277,565 $ 1,060 $ 640 $ 912 $ 280,177 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 June 30, 2018, $371 million of loans 30–89 days past due and $1.8 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 June 30, 2018, the amount of foreclosed residential real estate held by the Company, and included in other real estate owned (“OREO”), was $123 million ($103 million excluding covered assets), compared with $156 million ($135 million excluding covered assets) at December 31, 2017. These amounts exclude $237 million and $267 million at June 30, 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 June 30, 2018 and December 31, 2017, was $1.6 billion and $1.7 billion, respectively, of which $1.3 billion at both June 30, 2018 and December 31, 2017, 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.

(b) At June 30, 2018, $1.8 billion of GNMA loans 90 days or more past due and $1.7 billion of restructured GNMA loans whose repayments are insured by the Federal Housing Administration or guaranteed by the United States Department of Veterans Affairs were classified with a pass rating, compared with $1.9 billion and $1.7 billion at December 31, 2017, respectively. 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 to Lend Additional Funds June 30, 2018 Commercial $ 488 $ 860 $ 34 $ 170 Commercial real estate 230 481 8 – Residential mortgages 1,811 2,031 99 1 Credit card 233 233 61 – Other retail 308 387 19 5 Total loans, excluding GNMA and covered loans 3,070 3,992 221 176 Loans purchased from GNMA mortgage pools 1,665 1,665 38 – Covered loans 36 40 1 – Total $ 4,771 $ 5,697 $ 260 $ 176 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 June 30, 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 (Dollars in Millions) Number Pre-Modification Post-Modification Number of Loans Pre-Modification Post-Modification Three Months Ended June 30 Commercial 724 $ 132 $ 126 671 $ 62 $ 40 Commercial real estate 30 15 14 41 29 31 Residential mortgages 105 20 20 144 17 16 Credit card 7,461 37 38 8,146 40 40 Other retail 535 17 17 639 15 14 Total loans, excluding GNMA and covered loans 8,855 221 215 9,641 163 141 Loans purchased from GNMA mortgage pools 2,248 298 295 1,043 141 137 Covered loans – – – 3 1 1 Total loans 11,103 $ 519 $ 510 10,687 $ 305 $ 279 Six Months Ended June 30 Commercial 1,347 $ 213 $ 201 1,501 $ 199 $ 168 Commercial real estate 59 31 30 64 38 39 Residential mortgages 253 37 36 500 57 57 Credit card 16,007 80 81 17,551 85 86 Other retail 1,094 28 27 1,261 26 23 Total loans, excluding GNMA and covered loans 18,760 389 375 20,877 405 373 Loans purchased from GNMA mortgage pools 3,136 415 408 3,972 528 515 Covered loans – – – 7 2 2 Total loans 21,896 $ 804 $ 783 24,856 $ 935 $ 890 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 second quarter of 2018, at June 30, 2018, 44 residential mortgages, 22 home equity and second mortgage loans and 1,582 loans purchased from GNMA mortgage pools with outstanding balances of $13 million, $8 million and $208 million, respectively, were in a trial period and have estimated post-modification balances of $13 million, $7 million and $212 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 basis in connection with ongoing loan collection processes. For the commercial lending segment, modifications generally result in the Company working with borrowers on a case-by-case basis. Commercial and commercial real estate modifications generally include extensions of the maturity date and may be accompanied by an increase or decrease to the interest rate, which may not be deemed a market interest rate. In addition, the Company may work with the borrower in identifying other changes that mitigate loss to the Company, which may include additional collateral or guarantees to support the loan. To a lesser extent, the Company may waive contractual principal. The Company classifies all of the above concessions as TDRs to the extent the Company determines that the borrower is experiencing financial difficulty. 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. Modifications to loans in the covered segment are similar in nature to that described above for non-covered loans, and the evaluation and determination of TDR status is similar, except that acquired loans restructured after acquisition are not considered TDRs for accounting and disclosure purposes if the loans evidenced credit deterioration as of the acquisition date and are accounted for in pools. Losses associated with the modification on covered loans, including the economic impact of interest rate reductions, are generally eligible for reimbursement under loss sharing agreements with the FDIC.
