Blue, if I may... it is impossible to compare/assess prices for the commons with the ones for preferred shares. Nominally -as you do-, you may think that $1.45 or $1 for commons may relate to $4 or $5 or $6 for Jrs. as simple numbers stripped off any meaning. Specially now that Jrs. are not paying dividends and it looks they have lost their "special aurea".
The dollar figure assigned to commons shares has a direct impact on the final figure of the market capitalization of the company. The dollar figure assigned to preferred shares has no relationship to market capitalization of any kind. So although both "are numbers", they are not reflecting the same concepts. Thus, it is impossible to put them together as "equals". Preferred shares along with debt are measures of the enterprise value, not of the market capitalization. Comparing commons and preferred shares in an equal footing is like -literally- comparing apples to oranges. They are different instruments with no direct correlation, except if done in an arbitrary fashion (like when saying a conversion would take place at 7:1 preferred for common, which forces a relationship).
Better think twice. The fact that they currently do not pay dividends does not make them common shares. They still keep all other attributes that makes them preferred shares.
