They must sell $50BN worth of assets it seems: http://www.sbs.com.au/news/thefeed/...er-debt-which-national-treasure-would-you-buy
They aren't for sale, they will go into a fund to be run as a going concern to pay greek debt payments (possibly held as collateral as well). It doesn't matter anyway, the IMF won't play ball, the Greeks don't want it and even if it does get through (possibly by the IMF selling it's greek debt to the ECB) then they will still default again soon enough unless they get a really significant haircut or a reprofiling beyond reason.
Recently I've read about 15 airports being "privatized". Detail though: the buying "company" has as > 50% shareholders two German local governments. Privatized, how so?
