1261 ( e.d .
pa. ) and general refractories co .

pa. ) , name pca as a defendant based solely on the allegation that pca is successor to the interests of tenneco packaging inc .
and tenneco inc. , both of which were also named as defendants in the suits , along with nine other linerboard and corrugated sheet manufacturers .
the complaints allege that the defendants , during the period october 1 , 1993 through november 30 , 1995 , conspired to limit the supply of linerboard , and that the purpose and effect of the alleged conspiracy was to artificially increase prices of corrugated containers and corrugated sheets , respectively .
on november 3 , 2003 , pactiv ( formerly known as tenneco packaging ) , tenneco and pca entered into an agreement to settle the class action lawsuits .
the settlement agreement provided for a full release of all claims against pca as a result of the class action lawsuits and was approved by the court in an opinion issued on april 21 , 2004 .
approximately 160 plaintiffs opted out of the class and together filed about ten direct action complaints in various federal courts across the country .
all of the opt-out complaints make allegations against the defendants , including pca , substantially similar to those made in the class actions .
