I'm proud to present here the First Edition of the book entitled "Business Administration and Accounting" (on the heels of a preliminary version entitled "Lessons in business administration and accounting" edited in the year 2022) that represents a first effort to create a reference text in English containing the traditional concepts of Italian Economia Aziendale (Business Management), together with the foundations of the principles underlying accounting and the representation of values inside the financial statements in Italy. The book is divided into 16 Chapters written by professors of Business Management in the Italian Universities, and is mainly addressed to students of the Bachelor and Master degree courses in Economics Sciences held in English. This is a first edition, which collects didactic and research material with the aim of spreading the tradition of Italian Business Management and Accounting studies on the international scenario. In the first part of the book, in particular, the theoretical assumptions underlying the development of the studies carried out by Maestri (Masters) of Business Management in Italy are explored. In particular, after analyzing the definitional aspects of the Business Management science in organizations and firms, the business context of the companies is analyzed, as well as the Business strategy and the value creation. The concepts underlying the Italian studies on corporate governance and institutional structures, corporate organizations and business combinations, as well as internal control systems and management accounting aspects are also presented. The second part of the book analyzes the rules for preparing the financial statement according to the Italian accounting rules and principles. The framework for the analysis of the financial performance of corporate operations is initially described, as well as the strategic role of sustainability reports in representing non-financial information. After having dealt with the principles and assumptions of financial statements, structure and content of the Italian financial statements are described. After this analysis of the accounting system and the structure of the Italian financial statements, separate and consolidated ones, each single item is examined in depth, such as tangible and intangible assets, inventories, equity investments, receivables, payables and debt securities, derivatives and accounting for income taxes. Finally, some insights are made to the financial statement analysis, useful for the decision-making purposes of the stakeholders.
