From your link these words jumped out for me in reguards to EDIG not showing that much revenue after google:

"outstanding obligations or the need to provide something in the future would generally defer the revenue recognition."

What could be the obligations and which party has an obligation ?

Something, what could that something be?

What is really meant by the word defer?

I know what revenue is and means!!! I just want to see it on EDIG's reports, TIA
