This book outlines risk management theory systematically and comprehensively while distinguishing it from academic fields such as insurance theory. In addition, the book builds a risk financing theory that is independent of insurance theory. Until now, risk management (RM) theory has been discussed while the framework of the theory has remained unclear. However, this book, unlike previous books of this type, provides risk management theory after presenting a framework for it. Enterprise risk management (ERM) is seen differently depending on one's position. For accountants, it is a means for internal control to prevent accounting fraud, whereas for financial institutions, it quantifies the risk that administrators can take to meet supervisory standards. Therefore, most of the ERM outlines are written to suit the intended uses or topics, with no systematic RM overviews. This book discusses a systematic RM theory linked to the framework of it, unlike previous books that were written according to topic. After the Enron scandal in December 2001 and WorldCom accounting fraud in June 2002, several laws were enacted or revised throughout the world, such as the SOX Act(Sarbanes-Oxley Act) in the United States and the Financial Instruments and Exchange Law and Companies Act in Japan. In this process, the COSO(Committee of Sponsoring Organizations of Treadway Commission) published their ERM framework, while the ISO (International Organization for Standardization) published their RM framework. The author believes that the competition between these frameworks was an opportunity to systematize RM theory and greatly develop it as an independent discipline from insurance. On the other hand, the Great East Japan Earthquake that occurred on March 11, 2011, caused enormous losses. Also, because pandemics and cyber risks are increasing, businesses must have a comprehensive and systematic ERM for these risks associated with their business activities

This book is about retirement income security. This income security is provided by national public pensions, corporate pensions, and individual and reverse mortgages. However, these systems vary greatly from country to country and, in many countries, do not provide sufficient coverage. Ensuring income security in old age is an important issue that must be resolved in the rapidly aging environment of the world. From the perspective of financial consumers, this book cross-sectionally surveys public pensions, corporate pensions, individual pensions and reverse mortgages and compares them among many important nations. This gives many implications from the perspective of designing an overall income security for each individual. In addition, it presents many of the issues needed for these sustainable and comprehensive income security.
