ZURICH: UBS Group AG on Tuesday reported a 52% slide in profit for the first quarter due to an increase in legal provisions for a legacy litigation matter.

The result comes at a tumultuous time for the Swiss bank after it was forced into taking over former rival Credit Suisse.

Net profit attributable to shareholders came in at $1.03 billion versus the $1.71 billion average of 15 analyst estimates in a UBS-conducted poll.

UBS said it increased provisions relating to US residential mortgage-backed securities litigation by $665 million.
