You make it sound like with that $6M the turnaround is complete and everything is fine going forward. I don't think that's the case.
And your statement that "they only need cash to pay their monthly lines of credit and start paying down their accounts payable line" seems a little cavalier, given that that accounts payable line was $40.44M as of Sep 30.
Note that the accounts payable line is part of "Current liabilities", not "Other long-term liabilities". You're expected to pay your accounts payable on an at-least-relatively-timely basis.
