Cash reserves and FFP

I brought this question up on Arsenal TT page (in a friendly way) after their financial results were announced, but no-one knew the answer.
FFP is dependent on clubs not making a certain amount of loss. Arsenal for example may easily make a loss if they fail to make CL, yet they have £120-odd million in cash reserves. So how does this fit in? Are they actually allowed to make a loss up tp £120 and then use their cash reserve, for example?
Related to this I seem to recall in our figures the Sheik converted more equity to cash last season. If so does this make us have a cash reserve (however little) and put us in a similar position?
I'm interested in the treatment of cash already held to compare with the restrictions of FFP. Arsenal could potentially make a P and L loss of £120 and it is allowed. Either that or they are disqualified from using it!
