c) Transferred financial assets that are derecognized
 
in their entirety with continuing involvement
Continuing involvement in
 
a transferred and
 
fully derecognized financial
 
asset may result from
 
contractual provisions in
the particular transfer
 
agreement or from
 
a separate
 
agreement, with the
 
counterparty or
 
a third party,
 
entered into
 
in
connection with the transfer.
 
The fair value and carrying amount of UBS’s continuing involvement from transferred positions as of 31 December 2023
and 31 December 2022 was not material. Life-to-date losses reported in prior periods primarily relate to legacy positions
in securitization vehicles that have been fully marked
 
down, with no remaining exposure to loss.
