In it's conference call earlier, UnitedHealth (UNH -3.5%) CEO Stephen Hemsley reiterates its cautious stance on stated-based insurance exchanges, saying the company hasn't changed its view about selling insurance over exchanges set to open later this year under the health-care overhaul law. "We will be very selective in where we participate and do not believe the exchanges will be a significant factor for us," Hemsley noted. (Webcast).
