Unuse Honda SRA

I am a Honda dealer. I have my obsolescense under control, I am at 2.9%. I do however have some non-returnable "treasures". I am told there is way to "cash-in" at 50% if you are below 5%. I have the green light to to this and then scrap on my own, just not sure where to start. It has something to do with letting your SRA "roll- over" I also want to be a little careful not to get too much money back. I can probably only use 2-3K to get rid of the "junk" on hand. Are there any Honda dealers out there that have done this?
Thanks in advance for your help,
John
