We characterize the exchange property for non-unital rings in terms of their local rings at elements, and we use this characterization to show that the exchange property is Morita invariant for idempotent rings. We also prove that every ring contains a greatest exchange ideal (with respect to the inclusion). Copyright © 1998 by Marcel Dekker, Inc.
