Hank Greenberg testifies in reinsurance trial

• Former AIG Chairman Hank Greenberg took the witness stand yesterday to defend against claims that he orchestrated two sham deals to hide the insurer's financial condition from shareholders.
• Greenberg said he became aware of serious problems at AIG's auto-warranty business as early as 1998, but began taking steps to correct them the following year, and disagreed with the characterization that he was a "hands-on CEO."
