RBC Investor Services has expanded its relationship with Optimum Asset Management, a Quebec-based asset management subsidiary of Optimum Financial Group. The expanded mandate includes custody, fund accounting and shareholder services for OGP’s nine mutual funds. RBC previously provided custody, fund accounting and TA for six of Optimum’s funds. The relationship was expanded by transferring funds that were serviced by another custodian, consolidating all its fund servicing business with RBC.
