You would have to ask PWC why they worded that particular sentence that way. But it’s like asking why did they say “second” instead of “subsequent” or “follow-on”.
But it is abundantly clear from the Monitor’s reports via many many references to the sale of the plant that it was a result of the “second sale process”...which the company first revealed was going to have to happen in their July 31, 2018 PR when the SISP failed.
And for anyone confused by that particular sentence need only look a little further for a more detailed explanation.
The “second sale process” was the “liquidation sale process” that result in the plant (I.e. the operating asset) being sold.
