Pimco will not be changing its premier fund in the wake of Bill Gross' abrupt exit.
Scott Mather, Pimco's CIO for U.S. core strategies and manager of its Total Return Fund, told CNBC that the fund is well positioned, and will not see major strategic changes.
"We're not changing the fund," Mather said in an interview with "Street Signs." "It's been a team process here at Pimco. I and my colleagues have been involved in forming those investment themes which are at work in the Total Return Fund ... for 10 to 20 years."
