The operations provided about $8 million in cash of which $3 million went to investment and a little over $3 million went to pay down debt.
They have $6.5 million in long-term debt due in 2011, but I see no issue with them paying that off if they don't roll it over.
As for the increase in receivables, I don't think that is an issue, particularly given the quality of customers i.e. US government.
