Move over Smith Barney. The feds are now offering financial planning assistance. This week the Social Security Administration (SSA) launches the largest customized mailing ever undertaken by a federal agency with the distribution of SS statements to 125 million workers. Henceforth, the agency will send staggered mailings - approximately 500,000 each day - to workers ages 25 and older who are not receiving benefits. The annual statements are designed to assist Americans with retirement planning by providing estimates of retirement, disability and survivors' benefits.
