UBS is trying to rebuild after heavy losses in the US sub-prime market
Swiss banking giant UBS has said it expects to report a net profit of 2.5bn Swiss francs ($2.4bn; £1.5bn) for the first three months of the year.
The announcement came ahead of the bank's official first-quarter results, due out early next month.
UBS also said its clients had been taking their money out of the bank at a much slower rate during the period than in the previous three months.
Clients have been leaving UBS since the bank was hit hard during the downturn.
The bank reported a net profit of 1.2bn Swiss francs in the final three months of last year. This represented its first quarterly profit for more than a year.
UBS has been involved in a long-running dispute with US tax authorities. The US has accused UBS of hiding nearly $15bn in assets of US customers, and is seeking the account details of some of its US clients.
Shares in UBS closed more than 3% higher in Zurich following the bank's latest results forecast.
The announcement comes ahead of what analysts say could be a turbulent annual general meeting at the bank on Wednesday.
Shareholders are particularly unhappy at UBS's proposed bonus scheme, which many view as being far too generous, particularly in light of the bank's relatively weak financial performance during the financial crisis.
