In addition, the $1 billion in funding for the JV is coming from a different party entirely. If you read the PSC JV executive summary here you will see the following on the funding source:
PSC has been approved for over one billion dollars in funding from the “Funding Positive Change Organization” for all of its endeavors and subsidiaries. Unfortunately, we are not at liberty to divulge further details of the Private Funders at this time, as we are under a strong, Secrecy/NDA Agreement with them. PSC is expecting to receive its first draw of funds shortly.
There are obviously a lot of inter-dependencies here, so we should probably wait and see if this funding comes through and how things progress.
