U.S. regulators are set to choose the first non-bank companies likely to be branded potential risks to the financial system, according to two people with knowledge of the plans.

The Financial Stability Oversight Council intends to request confidential data from as many as five U.S. firms at a meeting this month, said the people, who declined to be identified because the plans aren’t public. The request is a step toward deciding whether the companies should be subject to Federal Reserve supervision, including stress tests, higher capital levels and tougher liquidity requirements.
