I was glad to see that the FTC unanimously approved new guidelines regarding endorsements and testimonials. The updated guidelines affirm the principle that material connections behind endorsements should be disclosed. This seems like a great time to offer my own disclosure information.
When I speak at a conference or event, I generally do not pay a registration fee for that event. Some conferences also waive registration fees for that event for one or more of my colleagues or a traveling companion. Either my organization or I pay my own travel and hotel expenses when I speak at an event.
