Cost Accounting Standards Board (CASB)
The Institute of Cost Accountants of India, recognizing the need for structured approach to the measurement of cost in manufacture or service sector and to provide guidance to the user organizations, government bodies, regulators, research agencies and academic institutions to achieve uniformity and consistency in classification, measurement and assignment of cost to product and services, has constituted Cost Accounting Standards Board (CASB) with the objective of formulating the Cost Accounting Standards.
Keeping in view latest legal and contemporary developments, the Cost Accounting Standards Board develops Cost Accounting Standards. To explain the requirements of Standards and provide the guidance with practical examples and illustrations on technical issues relating to Cost Accounting Standards issued by the Institute, CASB also issues Guidance Notes. Further, there may also be other technical issues relating to topics of importance for which the Cost Accounting Standards are not necessary but these technical issues need guidance to members and industry with respect to measurement, classification, assignment and presentation of cost in cost statements, the CASB issues Guidance Notes on such topics. The Institute/Board has so far issued 24 Cost Accounting Standards, Generally Accepted Cost Accounting Principles, 9 Guidance Notes on Cost Accounting Standards and two Guidance Notes on “Treatment of Costs Relating to Corporate Social Responsibility (CSR) Activities” and “Maintenance of Cost Accounting Records for Construction Industry Including Real Estate and Property Development Activity”.
The structure of Cost Accounting Standard consists of Introduction, Objectives of issuing standards, Scope of standard, Definitions and explanations of the terms used in the standard, Principles of Measurement, Assignment of Cost, Presentation and Disclosure.
While formulating the Cost Accounting Standards, the CASB takes into consideration the applicable laws, usage and business environment prevailing in India. CASB also gives due consideration to the Cost Accounting Standards, principles and practices being followed by the other countries in the world. If due to subsequent changes in the law, a particular standard or any part thereof becomes inconsistent with such a law, the provisions of the said law shall prevail.
