Computation of book profit for MAT now starts with Profit before Other Comprehensive Income; transition adjustments specified. The starting point for computing book profits for Ind AS compliant companies is Profit before Other Comprehensive Income. MTM gains and losses on FVTPL recognised through profit or loss are included in book profit, and MTM losses on such instruments need not be added back under clause (i) of Explanation 1 to section 115JB(2). Transition Amount is measured using Ind AS adjustments at the opening date of the first Ind AS reporting period; it excludes proposed dividend, deferred tax on transition, provisions for doubtful debts, and share application money reclassified to Other Equity, but includes equity components of financial instruments and service concession adjustments.
