SEGMENT INFORMATION

The performance of the company’s business segments are measured quarter to quarter without variations caused by special items, as management focuses on business segment operating profits excluding those items. Fourth quarter 2013 business segment operating profits and business trends compared with the prior quarter are as follows:

Industrial Packaging operating profits in the fourth quarter of 2013 were $486 million ($473 million including special items) compared with $517 million ($499 million including special items) in the third quarter of 2013. Box sales volumes improved relative to the market, however two less shipping days for the quarter and seasonally lower demand led to lower volumes. Profits for the segment benefited from the complete realization of the 2013 containerboard price increase.

Printing Papers operating profits were $143 million (a loss of $47 million after special items) in the fourth quarter of 2013 versus $144 million ($93 million including special items) in the third quarter of 2013. North America experienced fixed cost penalties and lower sales volumes resulting from Courtland’s partial shutdown in the quarter, partly offset by lower maintenance outages and improved sales price/mix. Brazil’s results improved largely driven by higher volume and better mix from seasonally stronger demand. Europe was negatively impacted by higher outages, while India improved with stronger prices and volume, along with no maintenance outages in fourth quarter of 2013.

Consumer Packaging operating profits were $32 million ($30 million including special items) in the fourth quarter of 2013 compared with $73 million (before and after special items) in the third quarter of 2013. Significant planned maintenance outage expenses and lower volume more than offset the impact of improved pricing.

xpedx, the company’s North American distribution business, reported operating profits of $5 million (a loss of $397 million including special items) in the fourth quarter of 2013 as lower demand impacted results, compared with $19 million ($13 million including special items) in the third quarter of 2013.

International Paper recorded Ilim joint venture equity losses of $12 million in the fourth quarter of 2013, compared with equity earnings of $11 million in the third quarter of 2013.The company recognized an after-tax foreign exchange loss of $6 million in the fourth quarter of 2013 compared with an after-tax gain of $8 million in the third quarter of 2013 due to foreign exchange movement in the U.S. dollar versus the Russian ruble. The impact in both quarters was due to non-cash adjustments associated with the Ilim Group joint venture’s U.S. dollar denominated debt.

Corporate items net, for the 2013 fourth quarter were income of $6 million compared with expenses of $13 million in the third quarter of 2013.

Effective Tax Rate

The effective tax rate before special items for the fourth quarter of 2013 was 31 percent, compared with an effective tax rate before special items of 24 percent in the third quarter of 2013. The higher rate in the fourth quarter is primarily attributable to a one-time inclusion in the third quarter of a $30 million benefit related to the adjustment of the tax basis in certain of the Company’s fixed assets. The 2013 full year rate was 27 percent compared with 29 percent for the 2012 full year.
