(7)Includes approximately $0.1 billion of residential first mortgage loans in process of foreclosure.
(8)Includes approximately $0.1 billion of home equity loans in process of foreclosure.
(9)Fixed-rate home equity loans and loans extended under home equity lines of credit, which are typically in junior lien positions.
(10)Consumer loans are net of unearned income of $676 million. Unearned income on consumer loans primarily represents unamortized origination fees and costs, premiums and discounts.

(1)The above tables do not include loan modifications that meet the TDR relief criteria in the CARES Act or the interagency guidance.
(2)TDRs involving changes in the amount or timing of principal payments may involve principal forgiveness or deferral of periodic and/or final principal payments. Because forgiveness of principal is rare for corporate loans, modifications typically have little to no impact on the loans’ projected cash flows and thus little to no impact on the allowance established for the loans. Charge-offs for amounts deemed uncollectible may be recorded at the time of the restructuring or may have already been recorded in prior periods such that no charge-off is required at the time of the modification.
(3)TDRs involving changes in the amount or timing of interest payments may involve a below-market interest rate.
Schedule of troubled debt restructuring loans that defaulted
The following table presents total corporate loans modified in a TDR as well as those TDRs that defaulted and for which the payment default occurred within one year of a permanent modification. Default is defined as 60 days past due, except for classifiably managed commercial banking loans, where default is defined as 90 days past due.

The difference between the domicile of the booking unit and the domicile of the managing unit is not material.
(2)Loans secured primarily by real estate.
(3)Corporate loans are net of unearned income of ($841) million and ($844) million at June 30, 2021 and December 31, 2020, respectively. Unearned income on corporate loans primarily represents interest received in advance, but not yet earned, on loans originated on a discounted basis.
