Subsequent Events	Subsequent EventsOn June 1, 2021, we completed the previously announced acquisition of Edmunds at an implied enterprise value of $404 million, inclusive of our initial investment. The consideration paid at closing included a combination of cash and shares of CarMax common stock. We expect Edmunds’ financial results to have an immaterial impact to CarMax’s earnings per share in fiscal 2022.
