Well, if that's the case, he should have been a little clearer because the PR says: "convertible debentures". A CD is debt which can be converted to some other kind of security in the company, usually common stock. As long as they aren't issuing tons of shares to a shady financer, they might be okay. It's always a good idea though to keep an eye on how the o/s grows.
