WINDSOR, Conn., Nov. 5, 2012 /PRNewswire/ -- ING U.S. announced today that its Retirement business has been retained as the service provider for the County of San Bernardino Defined Contribution Retirement Program. ING U.S.'s relationship with the County of San Bernardino -- the largest county by geographic size in the nation -- began in 1993 and has been extended pursuant to a two-year agreement. The program consists of a 457(b) deferred compensation plan, 401(k) and 401(a) defined contribution plans, as well as a retirement medical trust plan (HRA) and a 3121 plan for part-time employees. There are over $600 million in assets under administration and approximately 23,000 participants in the combined plans. "ING U.S. has provided exemplary service for these plans and our relationship continues to flourish due in part to the local, personalized attention we receive from the ING representatives based right here in the county," said Andrew Lamberto, Director of Human Resources for the County of San Bernardino. "We look forward to building on this successful foundation and implementing new services and strategies to help the many public employees of the County plan for and save towards a comfortable retirement."

We look forward to continuing to deliver outstanding services and solutions to help the employees of San Bernardino County achieve the financial security in retirement they expect and deserve."
