Sometimes it helps to make yourself a little chart. A June UY chart looks like this for your current point balances:
Use Year..........Vacation Dates.........Current Point Balance
2006.....Jun 1, 2006 thru May 31, 2007...0 points
2007.....Jun 1, 2007 thru May 31, 2008...10 points
2008.....Jun 1, 2008 thru May 31, 2009...150 points
2009.....Jun 1, 2009 thru May 31, 2010...150 points
2010.....Jun 1, 2010 thru May 31, 2011...150 points
and so on.
You want to take a vacation in November 2007. Looking at the chart, you see that timeframe occurs within your 2007 use year. So you must use UY 2007 points to make that reservation. Suppose it will take 125 points as an example.
You only have 10 points in 2007 UY, so you would borrow 115 points from 2008 UY. This would then give you 125 points in UY 2007, and leave you with 35 points in UY 2008.
You can make the reservation at 11-months ahead of your planned check-out date (for home resort). It makes no difference what use year month you have. It only affects which use year the points will come from.
For example, in your case, a November 2007 reservation requires June 2007 UY points. But for someone with a December UY, that same November 2007 would require their Dec 2006 UY points. (That's because their 2006 Use year covers vacation dates Dec 1, 2006 thru Nov 30, 2007)
But for both of you, you each can book at 11-months ahead (home resort) or 7-months ahead (non-home resort) for that reservation, even though your individual points would be coming from different Use Years. (UY 2007 in your case and UY 2006 in the other person's case)
Recap....
Banking: You may bank points from any use year in the table to the use year directly below it.
Borrowing: You may borrow points from any use year in the table to the use year directly above it. You may only borrow in order to make a reservation, and you may only borrow the number of points required to fulfill that reservation.
Hope this helps.
