This revised 10Q language is very interesting.  I believe the company is saying two things:

1) some license agreements (perhaps the J settlement licenses confirmed in the 10Q) after Nov. 30 may be different from those implemented previously.  I suspect some type of ongoing payments vs. the one-time payment.

2) due to this "highly interpretive area of accounting" it has not yet been determined precisely how the revenues from these revised agreements will be recognized.
