Personal approach here is to take a view on survival. Invest , but not too much, since risk profile is high. IMHO We have most of the negatives at current price, but no-one can discount Failure and loss of total stake. Upside is potentially strong. Cash looks ok, and whilst negative operating profits (sounds so much nicer than losses-don't you think!).Rating will likely lag the market for as long as this type of busines is perceived as low growth opportunity, but even on heavy discount to market average PE, the business doesn't need to make much profit to justify a significant improvement to Today's price.Not for the faint hearted or the kind of share to 'bet your house on', but I'm prepared to hold a small speculative element in my portfolio? ..As Always DYOR etc
