(1) Includes costs that are not directly attributable to our reportable segments. Corporate G&A also includes certain shared costs such as finance, accounting, tax, human resources, information technology and legal costs. Platform R&D also includes mapping and payment technologies and support and development of the internal technology infrastructure. Our allocation methodology is periodically evaluated and may change.
