My last thought on the pre-paid card..
For non-Shareholders:
It builds awareness to CMKX, and allows them choice of whether to activate the card or not. Regardless, it may well make some curious to read more about CMKX and become investors in the company. I would think passing these out at the races is one sure way to spread the word and goodwill. It is also a great way to grow and maintain a shareholder base.
For Shareholders:
You would have the same choice to receive and activate the card or not. However, if you are a shareholder and on record with an activated card, dividend distributions could come via the card, reducing expenses for the company.
I think that everyone would agree it's silly to pre-pay a visa card in cash to use it yourself. However, as a means to receive part or all of a cash dividend and/or give to others without heavy tax implications, that is benefit and a real possibility.
Be well, Bo
