ZURICH, Switzerland (AP) _ The top U.S. expert on Holocaust-era finances was to meet officials from Switzerland's three major banks Sunday in what are expected to be lengthy negotiations on compensation for victims of Nazi Germany.

U.S. Undersecretary of State Stuart Eizenstat requested the meeting with the top bankers, said Mathis Cabiallavetta, chairman of the nation's second-largest bank, Union Bank of Switzerland.

Cabiallavetta told Swiss radio that the meeting, to be held in Zurich, was meant to be secret. It was disclosed Saturday by the daily Neue Zuercher Zeitung.

But Cabiallavetta said a quick settlement Sunday was ``out of the question.''

Eizenstat wrote a report earlier this year accusing neutral Switzerland of providing financing to Nazi Germany that prolonged World War II. Jewish organizations have accused the banks of dragging their heels for 50 years in allowing Holocaust victims' heirs access to assets in dormant accounts.

But Eizenstat recently has praised Switzerland and its banks for the steps they have taken to make amends.

Among those efforts is a fund set up by major Swiss banks to help needy Holocaust survivors, especially those still living in Eastern Europe, where they suffered under decades of communism and more recent economic turmoil.

Rolf Bloch, president of the fund, said Saturday the first payments to non-Jewish Holocaust victims will be made Thursday, when 23 Albanian survivors of Mauthausen concentration camp in Austria are to receive the equivalent of $690 each.
