“Will trade again” could mean, just from the perspective of considering how a lawyer might be ABLE to interpret those words, that he shares that trade in the future will not be the same shares as those that are trading today.
I’m not saying I believe that will happen. But parsing the words, it could mean something like that. Imagine hypothetically that they were able to, say, put the GSEs in conservatorship. Well, then they could spin off a new company with new shares, and the phrase “the shares will trade again” would, in hindsight, still make sense.
