based in North America. Growth in revenues and operating profit in this segment is derived from retaining and growing the core busi- ness and improving the overall cost structure. Growing the core business comes primarily from an increase in account usage, growth from existing clients (also referred to as organic growth) and sales to new clients and the related account conversions. This segment has many long-term customer contracts with card issuers providing account processing and output services for printing and embossing items. These contracts generally require advance notice prior to the end of the contract if a client chooses not to renew. Additionally, some contracts may allow for early termination upon the occurrence of certain events such as a change in control. The termination fees paid upon the occurrence of such events are designed primarily to cover balance sheet exposure related to items such as capitalized conversion costs or client incentives associated with the contract and, in some cases, may cover a portion of lost future revenue and profit. Although these contracts may be terminated upon certain occurrences, the contracts provide the segment with a steady revenue stream since a vast majority of the contracts are honored through the contracted expiration date. This segment provides services throughout the period of each account’s use, starting from a card-issuing client processing an application for a card. Services may include processing the card application, initiating service for the cardholder, processing each card transaction for the issuing retailer or financial institution and accumulating the account’s transactions. The segment’s fraud management services monitor the unauthorized use of accounts which have been reported to be lost, stolen, or which exceed credit limits. The segment’s fraud detection systems help identify fraudulent transactions by monitoring each account holder’s pur- chasing patterns and flagging unusual purchases. Other services provided include customized communications to cardholders, information verification associated with granting credit, debt col- lection, and customer service. This segment has two major customers. Below is a summary of the North America Services segment: * Note: Segment operating results do not include expenses associated with Corporate Administration.
