(Reuters) -Swiss bank UBS Group AG has set aside $4 billion in provisions for potential litigation and regulatory issues stemming from its takeover of Credit Suisse, the bank said in a filing on Tuesday, as it prepared to complete the rescue of its Swiss rival.
UBS estimated a "negative goodwill" of $34.8 billion from its acquisition of Credit Suisse.
The transaction's massive one-off gain, a result of "negative goodwill" attached to the 167-year-old bank that has struggled for years with scandals and losses, will allow UBS to absorb one-off losses related to the takeover.
Analysts at Jefferies had said restructuring costs, litigation provisions and the planned winding down of the non-core unit could add up to $28 billion, but only some of that might be booked upfront.
Since UBS has yet to gain full insight in Credit Suisse's books, the numbers may change in coming months.
The deal – the first rescue of a global bank since the financial crisis of 2008 - will create a global wealth manager with more than $5 trillion in invested assets with more than 120,000 employees worldwide.
