The "Performance and Accountability Report: Fiscal Year 2005" shows a deficit of nearly $23 billion for the Pension Benefit Guaranty Corporation while estimating "future exposure to new probable terminations" at $108 billion, nearly four times the "damage".
In its primer on pension accounting and funding, the American Academy of Actuaries describes at least four types of numbers - service cost, accumulated benefit obligation, projected benefit obligation and present value of future benefits. They add that "Amounts calculated under pension funding rules are completely different than those calculated for pension accounting, and one must be careful not to mix the two topics."
Keep in mind that smoothing and credit balances are other considerations as we try to navigate our way through the maze of pension metrics. New rules that address (a) the treatment of a company's pre-funding of a plan and (b) whether a sponsor can continue to average a plan's value over several years could materially impact reported pension costs. (To the extent that capital market participants react to accounting numbers as inaccurate barometers of economic health, C-level executives could be busy with related financial tasks.)
Okay, we get it. There are lots of ways to measure pension deficits but which one tells us what we really want to know?
What is the truth?
Will the real pension deficit please stand up?
