According to a newspaper report, the major Swiss bank UBS is considering postponing its next interim balance sheet because of the planned takeover of its troubled rival Credit Suisse. The second-quarter report should not be published before the end of August, the Financial Times reported on Sunday, citing people familiar with the matter.

The three-billion-franc transaction is complicated. UBS also hopes to be able to use the figures to present an updated plan for Credit Suisse's Swiss business. Actually, the publication of the quarterly report is scheduled for July 25. UBS was not immediately available for comment.

UBS CEO Sergio Ermotti hopes to complete the planned takeover in the coming days. UBS is in the process of completing the last miles in a marathon, he said on Friday. At the beginning of May, Ermotti had held out the prospect of closing the transaction at the end of May or beginning of June.
