Current overhead expenses. I have been using quarterly overhead at ~$20MM. I think it will be closer to $25MM by the end of '11.
Overhead expenses? A good amount of these expenses are operating expenses (i.e., salaries paid to scientists, R&D development costs, royalties paid to MIT for mLovenox, etc.).
If MNTA wants to build out its FOB platform its going to need to investment money in R&D, scientists, etc. I think you should be looking at this additional spend as an investment vs. additional overhead expenses.
