Do acceptance rates account for waitlists?

Just saw on the Skidmore thread that their acceptance rate this year is calculated at 29%. At some point, will that be recalculated to account for the number of students who come off the waitlist? One of D’s schools (not Skidmore) accepted almost 100 off the waitlist last year. For a small school, that could drive the rate up a point or two. Just curious if that is included in what they report (and what outside agencies report.)

Yes Skidmore acknowleded that wait list numbers could tick that up a bit but they filled 50% of the freshman class with ED applicants.
