You should e-mail the company. SIGO management always e-mails me back quickly.
They explained all my question regarding the loan terms and the 6 month grace period and the paying back cash vs. stock.
Very satisfied with my Due Diligence.
Instead of constantly posing questions on the SIGO board, you should try a little effort and just contact the company. The owners are very nice and will explain everything.
Also, there is a shareholder open house on March 8th. If you own shares you should go and ask more of your questions.
