| Abstract: | The associations between three alternative measures of the unfunded pension obligation discussed in the accounting literature and a measure that reflects the present value of expected cash flows (economic liability) are examined in this study using simulated data. The sensitivity of the correlations to funding methods, growth rates of the plan population, interest rates, plan initiation dates, and extent of sweetening are also studied. It is shown that all the accounting measures of the pension obligation are highly correlated with the total economic liability when funding is excluded, but the correlations decrease significantly when the net (unfunded) liability is examined. Furthermore, it is shown analytically that one cannot predict ex ante which measure of the unfunded liability will be most highly correlated with the economic liability. The implication for accounting standard-setting bodies is that both the pension plan assets and pension obligations should be disclosed to facilitate users in making predictions about changes in the economic liability. A recent official pronouncement, SFAS 87, provides for such disclosure in most circumstances. |
