We’ve added products and benefits, shown continued strength in acquiring new customers, and expanded our merchant network.

“Loan growth continued to be strong and credit metrics were again in line with our expectations. We’ve contained operating costs and reallocated a significant part of those savings to fund many of the initiatives that are now driving growth across the business.

“Throughout the turnaround, we’ve dealt effectively with competitive challenges and redesigned our marketing, customer service and risk management capabilities for the digital age.”
