Different plan sponsors have different objectives for their retirements. There are positives and negatives. The challenge with pension benefits in general is that they are a fairly blunt instrument because they apply to high-income earners as well as to low-income earners. Often when we look at, say, removing a limit like the marriage after 60 limitation that's in the plan, the biggest beneficiaries of this are going to be the high-income earners.
This is not a method necessarily of targeting any specific subpopulation. The question is what we are aiming to do. If it's to, say, help ensure that low-income survivors are provided for in retirement, there are a great deal of costs and funds that are not going to be allocated to these members. It's a very small component.
