Just a question... why tender your shares for $72, when you could take $71.29 today?
If the deal goes through at $72, you lost very little. If it doesn't go through you'll be able to buy back in at $62?? (IMHO) :)
Of course you run the risk of losing out big if a higher bid appears, but the likelyhood of that isn't too great. Right now, management will try everything to keep their jobs. I'd wait to get very close to the date this thing gets voted on, and then sell on the open market.
OTOH, you could do a lot worse than hang onto your shares, the company has a $47 book value, made tons of cash last year, and should make a ton more this year. I suspect that if the deal doesn't go through, the shares wouldn't be down for long.
