Switzerland's UBS makes changes to executive board

ZURICH, Jan 24 (Reuters): UBS announced changes to its executive board on Wednesday as the Swiss bank presses ahead with its integration of fallen rival Credit Suisse.

Switzerland's biggest lender appointed Aleksandar Ivanovic to lead its $1.6 trillion asset management business, replacing Suni Harford who is retiring.

Beatriz Martin Jimenez will become the Lead for Sustainability and Impact on the global executive board in addition to her existing responsibilities, UBS added.

Both changes will take effect from March 1.

The changes come as UBS continues its integration of Credit Suisse, which UBS bought for 3 billion Swiss francs ($3.46 billion) in an emergency rescue last year.

Integrating the two arch rivals is a huge, multi-year task that will mean thousands of job losses in Switzerland and elsewhere and create a single financial institution with a balance sheet around double the size of the Swiss economy.
