This is just a theoretical maximum official reporting lag for the earliest sales in a given quarter.

From the investor presentation:

"OBJ receives royalties approx. 45 days from end of each quarter. 4C report delivered up to 210 days after the start of each sales quarter"

$127K for Jan-March Quarter 2017 gets reported in the June 4C which is released at the end of July. (about 210 days from 1st Jan 2017)

However the company can obviously report quarterly figures much earlier early as they did in the last revenue announcement. The company will know the June quarter figures in less than 2 months, and there is no reason why they won't report it early in late August or early September, especially as they have stated that the June quarter incorporates a ramp up of Wave I.
