The corporate transactions can be used to support but at the same time weaken solidity, solvency and competitiveness. The risks of the interest groups in the corporate transactions differ. They are affected by the future solvency of the company, restructuring or bankruptcy and the premature interruption of the initiated restructuring or bankruptcy and the stage of insolvency in which the arrangement will be carried out. Company, tax and insolvency regulations differ and thus affect widely the risk of repaying, cutting or losing the capital of the shareholder or the creditor, or the order of priority as well as the vitality of the company and the rehabilitating of the continuable business. The corporate transactions and insolvency indeed challenge the objectives, the regulation and the effects of these different judicial sectors.

This study focuses on the illustrating and analysis of the effects of company, tax and insolvency regulations on the corporate transactions, which are related to the insolvency and on the later judicial consequences of the change or termination situations of the company.

In addition, 146 (interim) financial statements of them were analyzed.
