Securian Financial Group on Monday said it closed its acquisition of Capital Financial Group Inc. (CFG) and its broker-dealer unit, H. Beck Inc., a move that boosts the size of Securian's advisor network by roughly 60%.

Based in Rockville, Md., CFG's H. Beck affiliate adds about 750 advisors to the existing network of approximately 1,220 advisors at Securian's broker-dealer arm, Securian Financial Services. According to the company announcement, CFG's compound annual growth rate during the three years ended 2007 was 17%, and Securian Financial Services' rate was 27% during that time.

St. Paul, Minn.-based Securian says the acquisition will boost efficiency and create more product and service offerings. CFG's senior management team will remain in place and do business from its Maryland headquarters. The deal was originally announced in September, and closed after receiving regulatory approval.
