I wouldn't call it common, but huge companies make huge mistakes from time to time (recall Enron, Nortel, etc. just a few years ago) and the investors in those companies are the ones who pay the price. In this particular case the "missing information" is worse than you think: BSC shares were at ~$160 less than a year ago with much the same assets now being priced at only $2 per share.
Remember though, the assets haven't disappeared: They still exist and are producing wealth in the economy. None of the included properties are going to evaporate. As with Enron's meltdown, business continues as usual under new ownership, with the old owners now holding significantly lighter wallets.
