American Express reported fourth-quarter net income rose 8% to $103 million for its International Card Services unit while the Global Network and Merchant Services division posted a 13% rise in net income to $399 million. AmEx’s Global Commercial Services net Q4 income more than doubled to $182 million. AmEx says the increase in International Card Services total Q4 revenue of $1.4 billion was driven by higher cardholder spending and higher net card fees. Total Q4 revenue, net of interest expense, for Global Network and Merchant Services, also rose to $1.4 billion, reflecting higher merchant-related revenues driven by an increase in global cardholder spending. Global Commercial Services total revenues increased 2% to $1.2 billion, primarily due to higher cardholder spending.
