(2) As it follows from Table 2 and Fig. 3, the dependence of the average ratios r 1⁄4 hD1 =D2 i on debt share wd is quite weak and can be considered as almost constant. The value of this constant increases practically linearly with the equity cost k0 from 1.22 at k0 1⁄4 10% up to 5.69 at k0 1⁄4 24% (Fig. 4).
