If I was just starting out with a new idea for a business and new it would be a while before I was cash flowing, I would (and my financial statements) necessitate renting prior to owning. For a company still in start up or early phase, as NWBO's products are in research and development, renting provides flexibility regarding resources that owning does not. Once NWBO is cash flowing at a level at which it could afford to own, it might make more sense to own. For our business, we have owned the building that housed our offices and rented the building. We find renting to be much preferable for many reasons. We have used permanent help and temporary help depending on the stage of progress and need of the services provided. NWBO is still in need of flexibility and given the volatility of the stock, the attacks, the nature of biotech requiring being light on feet to move quickly at new developments, renting seems to make more sense than owning. In addition, there are advances in manufacturing which will be made in the future according to some of their patents, that would indicate significant obsolescence at some point.
All relevant arguments and if expanded on by the company I would be more than happy. It would put the issue to bed IMO.
