Sorry if I am missing this, but I am a "new" points owner and have not made any reservations yet. If I want to rent something in 2015 and I need to rent points, I need to rent 2015 use year points, is that correct? Can I rent 2015 use year points and then make a 2016 reservation or a 2014 reservation? I am not sure I understand the use year and how it relates to reservations I make.
Use Year is calendar year for Legacy Points (which are points that enrolled weeks owners get in exchange for electing to turn their week over to points in any given year), and can be calendar year or fiscal year for Trust Points (points supported by the underlying ownership in the Trust). As an example, my Trust points run from 10/1/xx-9/30/xx so they overlap a normal calendar year cut off. The Use Year for Trust points is determined based on the first of the month after you close on the purchase if purchased from MVC...or if purchased resale, they remain whatever they were before the sale. And Legacy enrolled owners who also purchase Trust points from MVC can elect to have their Trust points synced to a Calendar Use Year for ease of keeping track (and most do). You can rent either Legacy or Trust points and they can be combined in the vast majority of cases to make a ressie (there are rare instances where you may need all Trust points....but again, this is very rare!!!)
So when using points, either your owned points or rented points, you use points from the Use Year that the first day your ressie falls into. That date of check in is the trigger date.
Keep in mind, owned points can be borrowed back a year, or banked forward a year. So if you have calendar Use Year points from 2015, and bank them forward, they are now Banked 2016 Use Year points and can only be used for ressies in the 2016 Use Year.
As to your question... if you rent 2015 Calendar Use Year points, can you use them for a 2014 or 2016 ressie...no you cannot. Transferred (or rented points as we like to call them) are locked into the Use Year they came from. So if you are renting 2015 Calendar Use Year points, they can only be used to snag a ressie whose day of check-in is during the 2015 Calendar Use Year. Again, if they are fiscal Use Year Trust points, you will have to make sure the points are good for the ressie dates you need based on the oddities of the fiscal Use Year limitation on those points.
Does that help. There are many nuances, so I don't want to provide too many examples, but hopefully I have provided enough to answer you questions.
Feel free to PM me if you have specific questions that you don't want to post in the thread.
