Krissy,
Debt for this company is certainly a concern. However, I think you misunderstand how they can build the company.
You have mentioned that they will have big trouble once 2014-2015 comes around, intimating that they must pay back all the money at that time. As DG said on the call (very intelligently) they can refinace the debt as time moves on and the growth plans for the company move forward. Depending on market conditions this could happen 2014 etc.
In any event, they have very clearly stated they have the funds to meet the near and mid term finacial obligations as the company grows.
Are you invested or just looking to help out the rest of us that cant figure it out?
