Hi Racy,This article does a good job of reviewing the considerations when deciding whether to take a lump sum or annuity.http://money.cnn.com/2007/01/29/pf/expert/expert.moneymag/index.htm?postversion=2007012911A key consideration is how long you expect to live - if you take the lump sum, then there is a chance you can outlive your money.
