Raw Materials Price Adjustment Formula

Formula

Pnew = Pbase×(1+Wp⋅ΔPigment+Ws⋅ΔSilicon+Wc⋅ΔCPI+Tar)

Description

Pnew = Adjusted price per unit

Pbase = Current price per unit

ΔPigment = % change in pigment index vs. baseline

Δsilicon = % change in silicon index vs. baseline

ΔCPI = % change in CPI vs. baseline

Wp, Ws, Wc = Weights for pigment, silicon, and CPI respectively (based on cost share)

Tar = imposed import tariffs
