My best guess is that one of the reasons bidders are not showing interest in the Kenmore line is that they operate off a stripped cost structure. If you have access to Kenmore landed costs, you will see that their landed costs are substantially less than branded equivalent landed costs.
The implication with stripped cost is that the seller (Sears) assumes all warranty liability for parts and labor vs branded product such as GE or Whirlpool where the manufacturer builds this warranty into the landed cost and therefore the landed cost on branded is greater than that of Kenmore.
The biggest drawback to stripped cost is that all parts and labor costs are absorbed by Sears in the form of unit charges. Over the years, the grand total for unit charges on parts and labor has to be in the tens, if not hundreds of millions of dollars. This is a large contributing factor to Sears’ imminent demise and is most likely a contributing factor to why investors are so reticent to purchase the Kenmore brand.
