1 Monthly income statement items of operations with a functional currency other than
 
the US dollar are translated into US dollars using month-end rates.
 
Disclosed average rates for a quarter represent an average of
three month-end rates, weighted according to the income and expense volumes of all operations of the Group with the same functional currency for each month. Accordingly, the weighted average rates for the second
quarter of 2023 and year-to-date June 2023 consider income and
 
expenses from Credit Suisse’s operations generated
 
since its acquisition by UBS. Weighted average
 
rates for individual business divisions may deviate
from the weighted average rates for the Group.
