While the company offers trading in a wide variety of products, the bulk of its business is in US and European government debt, mortgage-backed securities, interest-rate swaps, and US and international corporate bonds. The firm also sells fixed-income trading and price data, primarily through a deal with Refinitiv's Eikon service.

The firm also runs a much smaller diagnostic solutions segment that provides clinical trials testing, risk-assessment services, and information technology solutions.
