Real | 19.8% | 38.4% | 58.7% |

*Table 8 footnote: The rows in this cross-tabulation show whether the firm uses a nominal or real hurdle rate, the columns indicate whether cash flows are calculated in nominal or real terms. The fractions denote the number of firms for each combination relative to the total of 123 respondents that responded to both separate survey questions.*
