I went digging in the Form 4 data on the NASDAQ site. For anyone interested in inside sales I suggest learning your way around the NASDAQ site. It is the best place I know to see the actual data, not some reports about it. You can find reports saying what happened, but only the Form 4 data has the details and can be considered complete. All I found in my short look is the usual, a CEO receiving shares or options and selling a lot of them, but still owning a lot more. Keep in mind that it is common for most of an officer’s pay to be in options and shares.

Sorry for these being out of order, I wrote this as I looked at them.
Here is one Form 4 from early this month, 5 January 2018: http://secfilings.nasdaq.com/filingFrameset.asp?FilingID=124…
On that date the CEO, Stoecker, added 153471 shares worth of options owned directly, which vests and becomes exercisable as to 1/4th of the shares subject to the option on January 1, 2019, and thereafter vests as to 1/48th of the shares in equal monthly installments, until such time as the option is 100% vested…
It also shows that at that point he owned 240000 shares indirectly through some sort of limited partnership, plus 64673 shares directly.
The next one is for January 11. http://secfilings.nasdaq.com/filingFrameset.asp?FilingID=124…
It shows two sales by that partnership, each of 20k shares, leaving a balance of 200k shares.
The most recent form 4 for the CEO is for Jan 22: http://secfilings.nasdaq.com/filingFrameset.asp?FilingID=124…
This is essentially just like the last one, two sales by that partnership, each of 20k shares, leaving a balance of 160k shares.
Then I went back to his last form 4 of 2017, http://secfilings.nasdaq.com/filingFrameset.asp?FilingID=124…
If I read this right, that partnership received a block of class B shares, convertible to A, and started the cycle of selling the converted A shares in 20k blocks.
