FYI - I have yet to personally see a credit downgrade. They are a customer of the company I work for and the D&B indicated "good" credit. Funniest part to me was when they said they are in the "printing & construction" business, religion was not listed.
The likely issue is that you can't get a mortgage on contaminated property. Banks don't lend on buildings with issues like that. It might have caught them off guard so the cash grab could be to maintain a float rather than have a bank provide the service.
They will need a sizeable float to maintain construction of Wakhill.
I have also seen a fair number of special pioneers shipped out for assignment via airplane, so they are not acting like its a money issue with the ministry. Only construction, it further clouds the whole issue.
