Northern Trust Asset Management (NTAM), a global investment manager headquartered in Chicago, has appointed Thomas Swaney as executive vice president and co-head of fixed income, the company announced.

Swaney will share equal oversight responsibilities for the firm’s fixed-income strategies with Colin Robertson, a 35-year veteran of fixed-income investing who holds the same company titles as Swaney, the company said. Swaney and Robertson will work closely together as part of a succession plan for Robertson’s eventual retirement, the company said.

Swaney has served in senior roles at several global financial firms during his 25-year career, including managing partner with Lantern Harbor Investment Partners, a Boston-based institutional fixed income investment firm. He co-founded Lantern Harbor with Angelo Manioudakis, NTAM chief investment officer, to whom he will now report.

Swaney will join Manioudakis and Robertson on NTAM’s Investment Policy Committee, which sets investment policy for all Northern Trust groups in all asset classes.
