I believe its tied into your place in the waiver wire standings, and it may only matter at the point the deal is made (ie if you're ahead in the WW standings when the deal is offered, it may not matter if your behind when the deal is accepted, don't know for sure). I'm also not sure if it matters if you are ahead just 1 place in the WW standing or if you need to be 2 or more places ahead. There was a thread in the forums at some point that got into this a bit, don't remember the exact details its probably been a year or 2 in real life, so pretty far back and may be hard to do a search on.
