Footnotes aren't enough: the impact of pension accounting on stock values

Recent research has suggested that companies with defined benefit (DB) pensions are sometimes significantly misvalued by the market. This is because the measures of pension cost and pension net liabilities embedded in financial statements can provide a very misleading picture of pension finances, if taken at face value. The more pertinent information on pension finances is relegated to footnotes, which may not receive much attention from portfolio managers. Dramatic swings in the financial conditions of large DB plans around the turn of the decade focused attention on pension accounting practices, and growing dissatisfaction with current accounting standards has prompted the Financial Accounting Standards Board (FASB) to launch a project revamping DB pension accounting. Arguably, the increased attention should have made investors wise to the informational problems, thereby eliminating systematic mispricing in recent years. We test this proposition and conclude that investors continued to misvalue DB pensions, inducing sizable valuation errors in the stock of many companies. Our findings suggest that FASB's current reform efforts could substantially aid the market's ability to value firms with DB pensions.
