The FDIC and the Federal Reserve fined Discover Financial Services and its subsidiaries for misclassifying consumer credit cards as commercial, resulting in higher interchange fees.
Discover Bank has been ordered to pay $1.225 billion in restitution and a $150 million civil money penalty.
Millions of consumer credit cards were affected over 17 years, leading to over $1 billion in overcharged interchange fees for merchants.
Capital One Financial is set to acquire Discover Financial Services with approval from the Federal Reserve, and Discover has terminated the misclassification practices.
