Products and services from which reportable segments derive their revenues

Revenue reported above represents revenue generated from external customers. The inter-segment revenues and expenses have been eliminated in full.

For the purposes of monitoring segment performance and allocating resources between segments:

• all assets are allocated to reportable segments. Assets used jointly by reportable segments are allocated on the basis of the revenues earned by individual reportable segments; and
• all liabilities are allocated to reportable segments. Liabilities for which reportable segments are jointly liable are allocated in proportion to segment assets.
