Mortgage Banking [Abstract] |
Mortgage Banking Activity | Mortgage Banking Activity On July 1, 2020, as part of the IBKC merger, FHN obtained IBKC's mortgage banking operations which includes origination and servicing of residential first lien mortgages that conform to standards established by GSEs that are major investors in U.S. home mortgages, but can also consist of junior lien loans secured by residential property. These loans are primarily sold to private companies that are unaffiliated with the GSEs on a servicing-released basis. Gains and losses on these mortgage loans are included in Mortgage banking and title income on the Consolidated Statements of Income. Prior to the merger, FHN’s mortgage banking operations were not significant; however, at March 31, 2021, FHN had approximately $53 million of loans that remained from pre-2009 Mortgage Business operations. Activity related to the pre-2009 mortgage loans was primarily limited to payments and write-offs in 2020 and 2021, with no new originations or loan sales, and only an insignificant amount of repurchases. These loans are excluded from the disclosure below. The following table summarizes activity relating to residential mortgage loans held for sale as of the three months ended March 31, 2021 and the year ended December 31, 2020.

Mortgage Servicing Rights Effective with the IBKC merger, FHN made an election to record mortgage servicing rights at the lower of cost or market value and amortize over the remaining servicing life of the loans, with consideration given to prepayment assumptions. Mortgage servicing rights are included in Other assets on the Consolidated Balance Sheets. Mortgage servicing rights had the following carrying values as of the periods indicated.

In addition, there was an insignificant amount of non-mortgage and commercial servicing rights as of March 31, 2021 and December 31, 2020. Total mortgage servicing fees included in Mortgage banking and title income were $1 million for the three months ended March 31, 2021, and were insignificant for the three months ended March 31, 2020.
