The company defines a "new booking" as estimated future contractual revenues, including agreements with perpetual, multi-year and annual terms. Management regards the volume of new bookings achieved as one indicator of future revenues, but they are not comparable to, nor should they be substituted for, an analysis of the company's revenues.
