Performance was handed off to Accessories management, then not coincidentally the most profitable Performance parts
were gradually migrated to Accessory part numbers. This action alone made Performance as a whole appear to be an unprofitable waste of time
and gave Accessories a giant surge in sales.

Although I have to say the list is long...this is probably not a topic anyone would want to get me started on (at least, not without
an Alcoholic beverage of some sort readily available), that's probably the biggest factor right there.
