"How does an issuer print free trading shares for stock promotion purposes?"
Well, in LOCH (Loch-Harris), the company contacted most of its PP investors who had shares issued 12 months or more previously and offered them a 2-for-1 or a 3-for-1 deal to exchange the PPers' delegended, free-trading shares for new-issued restricted shares the company issued them on a 2-fer or 3-fer-1 basis.
The free-trading shares were then used to pay promoters, nott retired to the company treasury.
I don't know exactly the details of whether the shares were ever technically in the company's name - it's possibly the PPers' shares were handled by the TA as a direct transfer from PPers to promoters, with the company kind of brokering this deal.
Nott sure how it worked in detail, butt bottom line the company bought back free-trading shares from PPers with double or triple issuance of restricted shares and the free-trading shares were then used to compensate promoters.
