cotton, I believe the information you provided is just more proof that common shares stay intact and if there is a share exchange event which is likely, commons will be good and exchanged for NewCo issue.
Now look at the share structure below...to me this is a thing of beauty relating to keeping the current share structure in place during the reorganization plan that will be revealed on 2/18/2019
• Authorized Shares = 500,000,000
• Outstanding Shares = 108,992,750
• Insider Ownership is 70 Plus Percent after triggering buybacks of common to keep NOLs in place
• SHLDQ has over five billion in (NOLs) Net Operating Losses to use for 20 years forward
• The reason the share structure MUST stay intact is due to the (NOLs) Net Operating Losses and various other tax attributes which will make SHLDQ have a 15 to 30 percent advantage over competitors and may have made the ultimate difference in liquidation or staying intact as SHLDQ - DO NOT UNDERESTIMATE the value of various tax attributes.
While it is a fact that commons could be canceled while still able to use the NOLs, the problem with canceling commons is the NOLs would be SEVERELY restricted and not worth near their values should commons remain intact
