SLRW does not have a positive book value. It no longer exists, merely trading in limbo as a shell. When it was in operation, the assets listed were not accurately valued as was evident by its demise. It is far more likely that a real negative book value existed at that time. The unaudited financials filed in 2010 are nothing but relics at this point, and, were basically useless then given the assets listed.
