ESH08 close for 12/31

Hi -- I show Friday's close at 1475.50 -- same story, it seems, on the CME website. Daily Notes shows 1477.25. Am I missing something terribly obvious here? Thanks!

Tradestation has it the same as Daily Notes at 1477.25

And I've found 2 more sources reporting it at 1475.00 and 1474.75 ... hard to tell who is right. From a quick glance at the figures it looks like the lower numbers are more likely to be correct than the higher numbers.
