S&L would not be selling warrents into licensing news.. they would be selling held shares. They need to convert warrents into shares first, before selling on the market.
Hopefully PTSC/S&L have been in the process of retiring some of the warrents (up to 2 mil/qtr?), along with buying back shares on the open market, but there probably is only so much cash to do such with.. limitting the amount of shares we in retail would like to see bought back &/or warrents retired.
regards
corrections welcome
