Missouri State Employees' Deferred Compensation Commission, Jefferson City, hired CitiStreet as third-party administrator for the state's $1.2 billion 457 plan, said Randy Taylor, senior vice president at CitiStreet. Missouri state Rep. Mark Bruns, who chairs the commission, did not return phone calls for comment. CitiStreet replaces Nationwide Retirement Solutions. The plan offers about 30 investment options, said Mr. Taylor. CitiStreet will open an office in Jefferson City, its first in Missouri, to service the new account, said Mr. Taylor. The firm plans to hire 10 sales and service representatives. Mr. Taylor hopes to have the positions filled within the next 45 days, he said.
