Yesterday, Fastmarkets RISI (RISI) reported that Graphic Packaging (GPK, Hold)

announced a $60/ton price increase on bleached and unbleached boxboard effective

startup of Sappi’s (SAP-JSE, NR) 520k ton (~10% of North American supply) PM2

in Maine. Oversupply conditions persist given minimal capacity curtailments (~127k
