Section 128 in The Companies (Accounting Standards) Rules, 2006
128. In case of other long-term employee benefits, the introduction of, or changes to, other long-term employee benefits rarely causes a material amount of past service cost. For this reason, this Standard requires a simplified method of accounting for other long-term employee benefits. This method differs from the accounting required for post-employment benefits insofar as that all past service cost is recognised immediately.
