ACA to go bankrupt?

According to this report from Reuters, ACA will probably go bankrupt:

Bond insurer ACA Capital Holdings Inc (ACA.N: Quote, Profile, Research) is likely to go bankrupt, Pershing Square Capital's William Ackman said on Wednesday.

This was last Weds., which means that this is old news. It also explains why ACA has lost ~60% of its value in just three days. How soon it happens is hard to say. My guess is that it'll happen by the end of the week, maybe late on Friday like most bad news.
