Good point! I'll add that management is careful when selling shares on the open market not to hurt the closing price. The sales will be early in the day. In Q1, Mr. Clark increased the float by 101 million shares, all from the treasury, none restricted. In Q2, he increased the float 18 million shares from formerly restricted stock (no increase in issued/outstanding, thus not from the treasury).
He and Ryan have to pay the bills (including their salaries) with little operational revenue to use, so they are smart and prudent managers with their timing of share sales. By the way, there's no evidence of the company selling restricted shares to generate cash. If so, you'd see issued and outstanding shares increasing more than the float.
