A representative for Munich Re confirmed that company officials were being questioned by both the Securities and Exchange Commission and New York Attorney General's Office.

Anke Rosumek, reached at the company's Munich headquarters, said that the meeting concerned AIG but she said she had "no idea what the questions are about. This is an ongoing case." She also could not say where the session was taking place.

AIG said last week that its internal investigation of various questioned transactions and accounting procedures has found that although the company holds only a 19.9 percent ownership of Bermuda-based Richmond Insurance Company Ltd., there is "undisclosed evidence of AIG control." Its coming financial restatement will treat Richmond as a consolidated entity, AIG said.

Ms. Rosumek said Munich Re has a minority 49 percent stake in Bermuda-based Richmond and, "The participation is of relatively minor significance, book value is in low double-digit millions."

AIG said yesterday that Mr. Greenberg had resigned as director and non-executive chairman of Transatlantic Holdings Inc., the company's New York-based reinsurance operation. Mr. Greenberg was replaced as AIG's CEO on March 14.

Transatlantic also announced that Howard I. Smith and Edward E. Matthews had resigned as directors. Mr. Smith is the former AIG chief financial officer who was fired from the parent company when he invoked his Fifth Amendment right against self-incrimination rather than answer investigators' questions about reinsurance transactions that are suspected of improperly improving AIG's financial picture.

Mr. Matthews, according to the Princeton, N.J.-based Robert Wood Johnson Foundation, which he serves as a trustee, was formerly AIG senior vice chairman for investments and financial services, and is "a director of C.V. Starr & Co. and Starr International Company, private companies that control AIG."

Robert F. Orlich, Transatlantic president and chief executive officer, is now serving as interim chairman. Steve Skalicky, Transatlantic, chief financial officer, said the resignation letters from Mr. Greenberg and the others did not state a reason for their departure, but indicated they had no issues with the company.

The board intends to nominate its six current members, as well as certain new directors, to stand for election at the upcoming annual stockholders' meeting scheduled for May 19.

Mr. Orlich in a statement said Transatlantic, as an AIG consolidated subsidiary, "continues to cooperate in all investigations of AIG and related information requests. To date, nothing has come to our attention that would indicate that Transatlantic has been involved in any improper conduct."

Transatlantic, which operates worldwide, has consolidated assets of $10.6 billion and stockholders' equity of $2.6 billion.
