A U.S. unit of a U.K. company is expanding its presence out west.

Jackson National Life Insurance Company, Lansing, Mich., an arm of Prudential P.L.C., London, is moving its Denver operations to the 183,000-square-foot former Oracle I building at 7601 Technology Way in the Denver Tech Center.

Jackson National operations in Denver include Jackson National Life Distributors L.L.C., Denver, a distribution arm, and Curian Capital L.L.C., a registered investment advisor unit that offers separately managed account services to financial advisors.

Jackson National also has operations and service center staffers in Denver.

Today, Denver offices employ about 650 of Jackson National’s 3,000 U.S. employees, and that total probably will increase to 1,050 over the next few years, Jackson National says.
