Theoretical and methodological foundations of modeling the optimal structure of the working capital of a manufacturing corporation

The purpose of the article is to develop theoretical and methodological foundations for choosing the optimal capital structure of the production (operational) sphere of the enterprise of the corporate form of ownership, for which the risk of loss of financial stability is significant and which chooses its market strategy taking into account this risk. As you know, the return on equity invested in the costs of the production activity of the enterprise increases with the growth of the borrowed share, while the risk of the structure of the working capital from which these costs are financed also increases. The balance of benefits and losses actualizes the task of finding the optimal capital structure according to a given criterion. Within the framework of the formulated problem, the article substantiates the optimality criterion, offers a toolkit of models for optimizing the structure of the working capital of the operating segment of the enterprise for a short time- the results and conclusions of analytical calculations of optimal shares of financing of working capital for the most important cases of market activity of the enterprise are presented: in conditions of falling production and reaching its critical level, in conditions of availability of debt financing of costs at a fixed loan rate, and at a variable rate, the value of which depends on the volume of the loan and the risk of loss of solvency by the borrower (variable loan rate).
