No, that's not right. Shire effectively swapped the rights they held for ATC for additional shares in Avexa. If they were worried about Avexa, they would have held onto the rights as the share would be retained even if they were transferred to another company (eg if Avexa had gone bust). The fact that they chose to take shares in Avexa instead is in fact a big vote for Avexa, because Shire are bascially saying they can make more money having a direct interest in Avexa than they can having a direct interest in the drug.

As to why they haven't put up cash or assets now, I'm not sure why you think they would. I'm a shareholder in Avexa and I'm not going to send them a few extra dollars for the hell of it. Doesn't mean I don't support the company.
