We analyze the underinvestment problem as a determinant of corporate hedgin
g policy. We find evidence of a positive relation between a firm's derivati
ves use and its growth opportunities, as proxied by several alternative mea
sures. For firms with enhanced investment opportunities, derivatives use is
greater when they also have relatively low cash stocks. Firms whose invest
ment expenditures are positively correlated with internal cash flows tend t
o have smaller derivatives positions, which suggests potential natural hedg
es. Our findings support the argument that firms' derivatives use may partl
y be driven by the need to avoid potential underinvestment problems.
