Pimco had $25.5 billion net outflows across U.S. open-end funds

 Pacific Investment Management Co had $25.5 billion of net outflows across all of its U.S. open-ended funds in September, the bulk of them from its flagship fund, according to Morningstar data on Thursday.

Morningstar estimated net outflow for the flagship Pimco Total Return Fund of $17.9 billion in September, compared with the Newport Beach, California firm's figure of $23.5 billion.

Morningstar said the firm estimates open-end fund net flows by computing changes in assets from one month to the next that are not explained by the performance of the funds.

Morningstar also said estimated net inflows for the DoubleLine Total Return, a direct competitor of the Pimco Total Return Fund, at $1 billion in September. Total assets in the fund at the end of September were $35.6 billion.
