I think it was just a normal financing, but, alternatively, prepayments can be just 1% of the agreed upon amount. Let’s say 3 million is a milestone prepayment for submission (just an example), then it could be something like 300 million for submission, 600 million for acceptance and xxxxxxxxxxxxxx for approval. They’d leave the terms loose (not final) so they don’t have to announce too much too early. Example. In case not initially accepted.
Again, I think it’s just a normal financing, not something extraordinary.
