Absolutely the risk became greater. The risk became greater because they added a NEW PROJECT (US solar panel manufacturing facility) where other funding has yet to be secured.
as the risk of need was greater as they look at their operational space
They indicated that funding other than the need of the 14C has been identified and once secured the 14C will no longer be necessary and cancelled.
To specifically answer your question.
"What else would explain why they issue a 14c (insurance policy for the funding of the Med-RI),cancel a 14c(Other funding was secured 14C insurance no longer needed so cancelled), reissue a 14c (insurance policy for the funding of the US solar panel manufacturing facility) once other funding for this project is secured this 14c will be cancelled as well (etc)"
Least not forget, the chance of a much GREATER REWARD has also come with this greater risk.
