I am also pleased with the expansion of our sustainable solutions portfolio which is up 7% year-to-date versus last year," added Mr. Despite this, we have momentum from our composites investments, and we are realizing margin expansion from improved mix, pricing and cost reductions.  Tax adjustments include the net tax benefit/(expense) from one-time income tax items, the set-up or reversal of uncertain tax position reserves and deferred income tax valuation allowance adjustments.

Fourth quarter adjusted EPS increased 24% over the prior year pro forma adjusted EPS primarily driven by improved margins from positive portfolio mix, raw material deflation and cost reduction actions up 8% from Amortization of inventory step-up

It enables: • Increased rPET content • Reduced CO2 emissions When added to PET preforms and bottles, ColorMatrix AAzure helps to: • Improve bottle quality - Reduced preform acetaldehyde by up to 80% - Improved mechanical strength - Lightweighting • Improve processability - Reduced bottle blowouts - Reduced scrap - Improved productivity • Reduce energy consumption during bottle blowing process ColorMatrix AAzure has a slight blue tint, which is useful for off-setting yellowing often associated with the use of rPET, and has minimal impact on final product color or aesthetics. ColorMatrix AAzure can help to reduce the risk of off-taste by reducing preform AA levels by up to 80%. Care must be taken to optimize the bottle blowing process due to the increased heat- up rate of the preform, to take advantage of the many benefits offered by this product range.
