(1)
Intercompany revenues among our business segments are under agreements that are considered long-term.
(2)
Contracts are classified as long-term if all or part of the contract is to be performed over a period extending beyond 12 months from the effective date of the contract. Long-term contracts may include multi-year agreements whereby the commitment for services in any one year may be short in duration.
