The economic literature was consistent for a long time in the question that the time-value of invested money is independent from the capital-structure. The investment- efficiency calculations are not influenced by the decision concerned with the capital-structure. As the ‘shareholder aspect’ came to the fore, we can meet more often efficiency-calculations, where different yield requirements concerned with the equity capital and credits are charged, for the equity capital profitability requirements containing also the risk-premium requirements (as a rate independent of the capital-structure), for the credits only the returns of interest. Considering, that the prices of products realising on the competitive market do not depend on the capital-structure, the yield-requirement drafted on the principle of opportunity cost must be also independent of that.
