BERLIN (AP) — Deutsche Bank AG said yesterday it expects a charge stemming from the planned takeover of retail lender Deutsche Postbank AG to push it to a third-quarter net loss.

Deutsche Bank's shares fell sharply on the statement in a share sale prospectus posted on its website, closing down 4.5 percent at 44.75 euros ($58.51) in Frankfurt.

Germany's biggest bank currently owns just under 30 percent of Postbank. It announced its bid for a full takeover on Sept. 12. The bid will be underpinned by a planned capital increase, which it said this week will bring in some 10.2 billion euros.

Deutsche Bank is offering 25 euros per share for Postbank — a cash payment equal to the volume-weighted average share price over the previous three months.

The bank already said Sept. 12 that it would need to revalue its existing investment in Postbank, leading to a prospective third-quarter charge of about 2.4 billion euros.

Yesterday, it gave a slightly lower figure of 2.3 billion euros, but coupled that with more details of the third-quarter outlook.
