You bring up another interesting point. If I understand the structure, the bond company is a wholly owned subsidiary of CGRA. Per GAAP accounting, the bond company must be consolidated, for reporting purposes. So it would be CGRA (parent company) making interest payments directly to investors, but that is not what is being reported.
Also, given that the bond company is a UK company, CGRA should be using IFR (International Financial Reporting) for its quarterlies and annual financial reports.
Lastly, can you tell how much money has been used from bond proceeds for each of the 3 companies, as well as, the Powder River Basin project.
