Accounting Standard 15 (AS-15) addresses employee benefits excluding share-based payments, categorizing them into short-term, post-employment, long-term, and termination benefits. It details methods for actuarial valuation, particularly for defined contribution and defined benefit plans, emphasizing the use of the projected unit credit method for calculating obligations and expectations regarding demographic and financial assumptions. The standard also outlines disclosure requirements for financial statements, including reconciliations of benefit obligations and plan assets, as well as details on actuarial assumptions and their impacts.
