The quarterly report was released afterhours on Thursday, May 5th. Insiders' trading window started on either Monday, May 9th or Tuesday, May 10th. The trading window is 20 trading days. So by my estimates, Dale's last day to buy will be this coming Monday or Tuesday unless he is in possession of material nonpublic information. I am no expert in these matters so my estimate could contain errors. The SC 13D/A hasn't been released. In March, Dale submitted the SC 13D/A 2 days after his last form 4 was submitted even though there was plenty of time left in his trading window. There is a chance that Dale was buying on Friday.
