Refinancing risk and cash holdings

Although a firm’s use of shorter-term debt can potentially help it to reduce agency costs of debt and align managers’ interests with those of shareholders, the use of this type of debt increases the firm’s refinancing risk. We hypothesize that firms with debt that has a shorter maturity hold larger cash reserves to reduce important costs they could incur if they have difficulty refinancing their debt. Using a simultaneous equations framework that accounts for the joint determination of cash holdings and debt maturity, we find that firms that shorten (lengthen) the maturity of their debt increase (decrease) their cash holdings. Additionally, we document that U.S. firms have markedly shortened the maturity of their debt over the 1980-2008 period and that this can explain a large fraction of the increase in the cash holdings of these firms over this period. We also show that the market value of a dollar of cash holdings is higher for firms whose debt has a shorter maturity. Further, the inverse associations between the maturity of a firm’s debt with the level and market value of its cash holdings are more pronounced during periods when credit market conditions are tighter and refinancing risk is consequently higher. Finally, we show that larger cash holdings help to mitigate underinvestment problems resulting from refinancing risk. Overall, our findings suggest that refinancing risk is a key determinant of corporate cash holdings. * We thank Malcolm Baker, Travis Box, Murillo Campello, Amar Gande, Kathy Kahle, Swaminathan Kalpathy, and seminar participants at McGill University, Texas Tech University, Virginia Tech University, the University of Arizona, and the 2011 University of Innsbruck – Financial Markets and Risk conference for helpful comments.
