The planned international leasing reform involves the introduction of a so-called right-of-use approach. According to this, both finance and operating lease transactions must be recorded on the balance sheet of the lessee. In light of ongoing globalization, the question arises whether the right-of-use approach, in addition to its mandatory application to consolidated financial statements, would also be compatible with individual financial statements under commercial law and tax accounting. Against this background, the book discusses the commercial and tax law issues and addresses the different purposes of accounting as well as the principle of not recognizing pending transactions. After a critical analysis, the work concludes with a proposed solution.
