"Hassan Salman, who was wounded in the 2007 shootings, told CNN that 16 of the 17 families of the dead agreed to $100,000 lawsuit settlements from Xe, as Blackwater now calls itself. Those wounded were offered between $20,000 and $50,000 apiece, Salman said."
$100,000 seems to me a low figure for a family who lost a loved one because some guards got spooked. Keep in mind that Blackwater's revenue from its contracts in Iraq has exceeded $1 billion, and it turns out they have secret contracts with the CIA that are no doubt high-profit as well.
A 2009 US government audit found that Blackwater had violated terms of the contract and that "Pursuant to the contract, which has cost the government over $1 billion, such violations should have resulted in nearly $55 million in penalties to Blackwater."
