The level of standardization of accounting information (e.g., items of financial statements) that makes the financial statements of different entities comparable to each other. This includes comparability of information in financial statements across periods (when there is a change in an accounting policy or estimate) and comparability between entities across jurisdictions (and within a given jurisdiction: at a country-level).
Comparability is a qualitative characteristic that enables users of financial statements to identify and discern similarities in, and dissimilarities among, financial information/ items, and the impact of that on their information needs/ expectations/ decisions.
