Well this bump up sure should make the Insurance Companies books look sweet! After all it was an "engineered IPO" so they could recognize value. Ought to make their end of year books look totally sweet! Well done!
Well, I think we need to distinguish between the effects of the IPO and what has happened since then.
Yes -- of course the IPO (October 2009) was engineered to benefit the company's (pre-IPO) owners. Aren't all IPO's engineered to do that? What's the point otherwise? And yes, I would say the IPO was successful.
What has happened in the subsequent 14 months has been a function of the market, and the secondary offering a couple of months ago. Many of the large pre-IPO owners currently hold only a fraction of what they had previously, and so have not participated in the recent run-up, at least not to the extent they would have if they had held. There are exceptions to that. The most important exception, IMHO, would be Berkshire Hathaway, which sold into neither the IPO nor the secondary offering. Yes the runup has certainly benefited Warren Buffet. Given the size of Berkshire Hathaway, I’m not sure it will warrant even a footnote in BH's annual report, but their decision to hold still speaks volumes.
