Now that doesnt worry me so much for 3 reasons.
Firstly, at the current exchange rate this represents about three US dollars.
Secondly, it's probably going to turn up when they look down the side of the sofa.
And thirdly, it's not really lost - all you can say is that today's inaccurate guess at the value of the world economy is less than yesterday's inaccurate guess.
Don't lose sleep - and vote Stan.
