SAN FRANCISCO AP – Yahoo Inc. Chief Executive Jerry Yang pushed for an employee severance program that made it more expensive for Microsoft Corp. to engineer a takeover even after an outside consultant questioned the plan’s generous benefits, according to previously sealed documents in a shareholder lawsuit against Yahoo.

The details about the severance program and other information about Yahoo’s efforts to thwart Microsoft’s takeover bid became available Monday after a Delaware judge released redacted portions of a shareholder complaint filed last month after Microsoft withdrew an oral offer to buy Yahoo for $47.5 billion, or $33 per share.
