In this article, we investigate the role of pension obligations, the most significant off‐balance‐sheet item, in determining corporate debt maturity and spreads. We begin by showing a significant and robust positive relationship between pension liabilities and corporate short‐term debt ratio. We also find that more pension obligations cause a significant increase in the cost of debt, but this effect is mitigated by short‐maturity debt. Overall, our study shows that short‐term debt can reduce asymmetric information costs related to pensions.
