LUCERNE, April 10 (Reuters) - UBS Chairman Colm

Kelleher reiterated the Swiss bank's intention to repurchase

shares to the tune of $3 billion in 2025, despite looming

capital rule changes and global uncertainty.

"In the absence of any significant, immediate changes to the

current capital regime, we remain committed to returning capital

to our shareholders," he said at the bank's annual general

meeting in Lucerne, Switzerland, on Thursday.

2025 would be a very challenging year for markets, with much

uncertainty, Kelleher added.
