falconjet,
Thank you! Now I get it.
Now, the last question...does the A plan pay out for the rest of one's life or is it for a finite period of time?
At my company, there are bunch of options. The above example would yield the "Single Life Annuity" which is payable for the rest of your life.
You can also take a 10 or 15 year Certain Life Annuity, which pays a sum for a 10 or 15 year period, regardless of how long you live. If you are dead, it pays to your estate.
Then there are the joint and survivor options; 100%, 75%, 66 2/3%, and 50%. These options pay one amount for the rest of your life, then pay another amount for the rest of your spouse's life. The 100% pays the same amount for the rest of both your lives, the 75% pays one amount for the rest of your life, then 75% of that for the rest of your spouse's life, etc.
For all of these options, you start with the single life annuity and make corrections from there. The joint and survivor options depend on your age at retirement and your spouses age at retirement. If she is young, statistically she will live longer, so her monthly payout would be less than an older spouse.
My company has a 50% lump sum option, which pays half of the assumed value of your retirement plan up front at retirement. You can roll that tax-free into an IRA. Then all of the above options are reduced by 50%. It is interesting to note that many of the options utilize actuarial numbers updated annually by the government which are based on life-expectancy. For the 50% lump sum option in 2004, the factor is 13.099874 for someone retiring at age 60, meaning your average life expectancy is 73.099874 years. If you live longer than that, then you would have been bettter off not taking the 50% lump sum option. Of course, if you took the 50% lump sum option and invested it wisely then it would be a wash, but you are assuming the risk, not the company at that point.
A lot of people take the 50% lump option because they get at least some of the money right now, and they won't be totally SOL in case the company goes broke at some point in the future. I think it makes sense to do that.
