US Q1/15 Marketshare

It is likely American Express will continue to lose U.S. marketshare to Visa (VS) and MasterCard (MC) in the first quarter, with MC doing the most damage, according to forecaster RAM Research. The AmEx erosion will continue throughout 2015 and will be impacted in the second quarter of 2016 when AmEx ends the Costco card, which accounts for 10% of AmEx Cards-in-Force (CIF).
