For what its worth, I see the language in the NR as a positive, and is expected.
As discussed here at length, if a final report were to be produced on all the optimizations, that would be material to CUU and have to be made public. The details contained within the report are likely part of what I suspect are negotiations right now. By saying the report isn't done yet, there is nothing that has to be issued publicly and the negotiations for Schaft can happen as the JV has seen a "draft" of the report. I suppose any negotiations can continue until there is a deadline of what the 2020 Program should be, but the JV could also postpone that as well if negotiations are ongoing. Hopefully things are wrapped up by then.
