UBS did not suffer any losses overall in its trading business after the Swiss National Bank's (SNB) decision to abandon its currency cap, the bank said today.
It also confirmed it would return cash to shareholders after a restructuring.
Zurich-based UBS is the third of Switzerland's three biggest listed banks to say it did not suffer losses after the SNB last week suddenly scrapped its three year-old cap on the Swiss franc.
Credit Suisse and Julius Baer made similar declarations this week.
"In aggregate, UBS did not experience negative revenues in its trading businesses in connection with the announcement," UBS said in a statement.
The end of the cap sent the Swiss franc soaring, putting big Swiss companies which have a large portion of cash in foreign currencies but report in Swiss francs under pressure.
UBS said it would give more information on its outlook for the current quarter when it publishes figures on February 10.
The bank also confirmed its capital return to shareholders following a corporate restructuring would be 0.25 Swiss francs per share.
This will be paid once it has completed the squeeze-out procedure for shareholders who have yet to tender their shares in the exchange programme.
UBS had previously promised a supplementary capital return of at least 0.25 francs per share, as it expects the new structure will allow it to qualify for a capital rebate under Switzerland's too-big-to-fail requirements.
