In recent years there have been many news stories about the financial burden that pension plans have placed upon old-line companies in the automobile, steel, and airline industries. At a time when companies in these industries faced stiff competition from newer companies, the old-line companies needed to make large contributions to their pension plans, as a result of their deterioration in funded status. This article summarizes the events that led to that deterioration and the interim relief that Congress provided with the Pension Funding Equity Act of 2004 (PFEA), then subsequently modified and extended permanently with the Pension Protection Act of 2006.
With the downturn in the stock market in recent years, many pension plans of large companies experienced significant asset losses that led them from the overfunded status that had existed for a large part of the 1990s into underfunded status. Because these plans are subject to the minimum funding requirements of the pension laws, the asset losses must be paid for through increased minimum funding requirements. While almost all pension plans required additional contributions, pension plans of large companies were especially impacted because of the additional funding rules that apply to these plans.
For large pension plans, one part of the minimum funding requirement is based upon the difference between the plan's current liability and the value of the plan's assets. The current liability is a measure of the value of the benefits earned to date and is generally calculated using an interest rate based upon the interest rates on 30-year Treasury securities as specified by the Commissioner.<1> The contribution based upon this difference is called the deficit reduction contribution (because it makes up the deficit between the current liability and the value of the plan's assets). The deficit reduction contribution (DRC) resulted in relatively large increases in contributions for employers with large underfunded plans, many of whom had no funding requirements for the prior few years.
