(Bloomberg) -- Bill Gross's Janus Global Unconstrained Bond Fund was removed from a list of up-and-coming strategies compiled by Morningstar because of performance and questions about the fund's management, the Chicago-based researcher said Tuesday.

The fund was taken off the list "because returns have been so-so versus major bond indexes, and there are questions about the resources behind Gross following the removal of Kumar Palghat as the co-manager," Morningstar said in a note about its third-quarter 2016 prospects list.
