Thanks to l2007s who called to my attention that I had mis-read the 10q amounts recognized for the quarter that ended 2/28/13. I mistakenly listed that the 10q showed $2.42M in revenues for licenses sold that quarter, but in fact, that was the amount for that quarter from 1 full year prior. I read it as 2013, instead of 2012. My mistake, and thanks to Laurie for picking it up.

So it appears as though either Sierra paid nothing, or their payment was deferred to a later date. Time will tell, I suppose, though it will be hard to know if the payment was deferred, as typically, those amounts are not distinguished with who paid them.
