________________________

(1) We remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which are generally 21.0%. Those items that reversed in 2018 were remeasured using a tax rate of 32.9%. We recorded a provisional decrease to deferred tax assets of $23.9 attributable to the rate reduction and a provisional tax liability of $4.0 related to transition tax for 2018. During 2019, we recorded adjustments reducing the impact of the rate change and the transition tax by $1.0 and $0.6 respectively, representing a tax rate reduction of 1%.

(2) The tax basis of PolyVision exceeded the book equity of the entity. For United States federal tax purposes this generated a capital loss and related benefit, which varied from the expected US Federal tax expense on the financial statement gain on disposal.

(3) The valuation allowance provisions were based on current year activity, and the valuation allowance adjustments, including a reversal of valuation allowance at an affiliate in the U.K., were based on various factors, which are further detailed below.

(4) Investment tax credits were granted by the Czech Republic for investments in qualifying manufacturing equipment.

(5) The increase in the cash surrender value of COLI policies, net of normal insurance expenses, plus maturity benefits are non-taxable.

(6) The foreign operations, less applicable foreign tax credits, amounts include the rate differential between local statutory rates and the U.S. rate on foreign operations.

(7) Scheduled changes to the French corporate tax rate resulted in the revaluation of certain deferred tax assets of our French tax group.
