Your 2008 allocation starts Dec 1, 2008. I know it seems a little wacky with December use years, because they are almost the polar opposite of a calendar year.
It appears 67 points were borrowed from the Dec 1, 2008, use your to the current Dec 1, 2007, use year. Those points will have to be used for a stay by Nov 30, 2008, or lost.
The 83 points will have to be used by Nov 30, 2009, or banked by July 31, 2009, into the Dec 1, 2009, use year.
