When you're dealing with something like pension plans or employee benefits, the first factor is whether the plan is funded, whether there's an asset base behind it. Once there's an asset base behind it, it depends on what the investment policy of that asset base is, which will result in what the assumed rate of return is for the assets for that particular pension plan. There are assets there, they are invested in certain types of investments, and there's an expectation that there will be a return.
That rate is what is used for the funded pension plan.
