A unit of Minnesota Mutual Insurance Company is teaming with a neighbor to go after big ancillary benefits contracts.

Minnesota Life says its Securian Life Insurance Company subsidiary will underwrite a new family of Securian Dental dental plans aimed at large employers and add a related family of group life plans.

Units of DeCare International, Minneapolis, a dental benefits company, will administer the dental plans.

Minnesota Life and DeCare already have been working together on efforts to sell dental plans to small and midsize employers.
