Other revenue. Other revenue for the Information Services & New Markets business area is derived from training, sales of informational materials and line connection fees for members.
OMXs Market Technology business area provides technology solutions for trading, clearing and settlement information dissemination and also offers facility management, integration and advisory services. Revenue is derived from three primary sources: licensing, support and project revenues, facility management revenues and other revenues.
License, support and project revenue. License, support and project revenue are derived from the system solutions developed and sold by OMX. After OMX has developed and sold a system solution, the customer licenses the right to use the software. Each project involves individual adaptations to the specific requirements of the customer, for instance, relating to functionality and capacity. This development, testing, licensing and installation work generates project revenue that is invoiced periodically and is based on the degree of completion. When OMX provides a system solution, it undertakes to upgrade, develop and maintain the system and receives regular support revenues for this work. With regard to major system solutions for customers such as exchanges and clearing organizations, license and project revenue is mostly fixed and recognized in relation to the degree of completion. Support revenue is mainly fixed and contracts usually last for five years.
Facility management services. Facility management services involve OMX assuming responsibility for the operation of a system platform for a customer, for which OMX receives recurring facility management revenue. Revenue from Facility Management Services can be both fixed and volume-based. Contract periods vary between one and seven years.
Other revenues. Other revenues are comprised mainly of revenue from consulting services and exchange rate differences. Other revenues also include possible capital gains from the sale of operations.
