Pension or "defined benefit" plans are in a state of decline in more ways than one. Thousands of pension plans have been terminated in recent years. The vast majority of them were fully funded, but were frozen by healthy companies, like IBM, Verizon and Hewlett Packard, looking to save money.
Years ago, I was quoted in Newsweek as having said, "If you can't get by on the wise 4 percent withdrawal rate [from your retirement nest egg], you should have a serious talk with yourself and your spouse about your priorities, trade-offs and aspirations." While it's certainly nice being mentioned in a national publication, the material I contributed to the article had nothing to do with withdrawal rates from retirement portfolios. And financial planning rules of thumb are next to useless.
