We are living in a “flat world” of international integration and adaptive trends. This requires countries to integrate their own regulations to those from other countries. Accounting regulations are no exception. It is necessary to measure how much a nation’s accounting regulations are the same or different from those of another country or from International Financial Reporting Standards (IFRS).Extant literature reveals a rich discussion about this topic. Many measurement schemes have been initiated and employed. However, it is argued that data classification processes in those works contain some flaws. This paper contends the data specifically used to evaluate accounting measurement issues. The data will be divided into initial and subsequent recognition because such partition collectively affects the financial report figures. Therefore, the similarity of accounting regulations as a whole should be the multiplication of initial and subsequent recognition similar degree. To this extend, this work contributes to the research theme.
