It is true that Berkshire Hathaway is now over The Pampered Chef, but Pampered Chef does not contribute to what Berkshire does.
Also, after being purchased, Doris Christopher, the founder of Pampered Chef went to Warren Buffet and told him how donations from Berkshire were hurting Pampered Chef's reputation. Berkshire Hathaway no longer donates.
The only things donated to with Pampered Chef funds/earnings are what The Pampered Chef decides on.
