Two former chief executives of the engineering giant Siemens and four other onetime officials have agreed to pay a total of €18 million in damages resulting from a long-running bribery scandal, company executives said Wednesday.

Siemens last year threatened lawsuits against 11 people it accused of supervisory failings related to the scandal, which hurt the reputation of the company as well as its bottom line. Siemens has paid €1.6 billion, or $2.4 billion, to settle legal actions in Europe and the United States, as well as €800 million in legal fees.

Siemens, based in Munich, said Wednesday that it had reached settlements with 6 of the 11, including the two biggest names: Heinrich von Pierer, who ran the company from 1992 to 2005; and his successor, Klaus Kleinfeld. It did not disclose the amounts.

But an official at the company said the settlement amounted to about half of each of the former executives’ net assets. Mr. von Pierer will pay €5 million, said the official, who asked not to be identified because of company policy.

Mr. Kleinfeld, who now runs Alcoa, will pay €2 million, the official said. Uriel Sharef has agreed to pay €4 million; Jürgen Radomski and Johannes Feldmayer, €3 million each; and Karl-Hermann Baumann, €1 million. All are former board members.

Settlements with three other executives were previously announced, while claims against two others are pending because they are still under investigation by prosecutors.

The scandal surfaced in 2006, as investigators uncovered evidence of bribery and kickbacks in more than a dozen countries where Siemens operated and bid for contracts. By the middle of 2007, Mr. von Pierer and Mr. Kleinfeld had resigned, though the dispute over who was responsible rolled on. Both have denied wrongdoing.

Paying bribes abroad became a crime in Germany in the late 1990s.

While Siemens sought to portray the latest settlements as a milestone, anticorruption campaigners were less satisfied.

“I think it’s too low, compared to the damage,” said Peter Fries, a lawyer with Transparency International.

The two ex-board members still being investigated are Thomas Ganswindt and Heinz-Joachim Neubürger, a former chief financial officer. In the absence of a settlement soon, Siemens is likely to file a civil lawsuit before the annual general meeting scheduled for Jan. 26, the Siemens official said. Shareholders will vote on the settlements at that meeting.

While the settlements with the six executives preclude litigation from Siemens, they do not end inquiries by state prosecutors.

Barbara Stockinger, a spokeswoman for the Munich prosecutors’ office, said that eight investigations were still in progress. She confirmed that these included cases against Mr. Ganswindt, Mr. Neubürger and Mr. Sharef; in five other cases, she declined to identify the individuals. She said, however, that of the six executives whose settlements were announced Wednesday, not all were under investigation.

Andreas Wirth, a lawyer for Mr. Ganswindt, said that even if Siemens filed litigation against his client, an agreement was still possible.

“We have come close already,” he said, “and we expect to settle.”
