Sanctity of the arbitral tribunal’s interpretation of complex financial formulae

reinforces that an arbitrator’s mathematical and contextual reading of contractual pricing adjustment clauses must be respected by supervising courts. Where contractual clauses govern price adjustments across dual currencies—such as domestic currency and foreign currency components—the determination of adjustable portions against non-adjustable minimums is entirely within the arbitrator's interpretative jurisdiction. If an employer asserts an inadvertent drafting mistake in the contractual price adjustment formula, an arbitral tribunal is fully justified in declining to rewrite the terms of the bargain or correct alleged employer errors contrary to the plain text of the agreement. A harmonized, textually viable construction that gives commercial efficacy to foreign currency indexing falls strictly within the realm of reasonable contractual interpretation and is immune from judicial reversal under Section 34 or Section 37.
