Tim Cook, in an email posted by Mac Rumors:

I am very happy to announce that we are kicking off a matching gift program for charitable donations. We are all really inspired by the generosity of our co-workers who give back to the community and this program is going to help that individual giving go even farther.

Starting September 15, when you give money to a non-profit 501(c)(3) organization, Apple will match your gift dollar-for-dollar, up to $10,000 annually. This program will be for full-time employees in the US at first, and we’ll expand it to other parts of the world over time.
