Net worth threshold determines mandatory Ind AS adoption; voluntary adoption is irrevocable and affects consolidated reporting. Net worth for Ind AS applicability is calculated from a company's stand-alone audited financial statements as at the reference date or its first audited year after that date; meeting the threshold at that audit date fixes applicability even if net worth later falls. Ind AS apply to both stand-alone and consolidated financial statements, Indian parents must prepare consolidated statements under Ind AS while overseas investees may follow local rules, and voluntary adoption of Ind AS is irrevocable.
