In the April shareholder letter it states that the first draw on the financing would be by June 15.
Depending on the form the private placement takes, there are filings/registrations that would be required:
If the placement is dilutive, there would be a registration, if its non-dilutive then there would be Form 4s presumably? If it uses Reg D (which I don't know is practice for public) then there would be a Form D filed within 15 days of the first "sale".
