The second quarter market shares improved sequentially from the first quarter and several of their categories in North America including diapers.

North America organic sales increased about 6%, sales volumes were up 3% and higher net selling prices driven by a lower level of promotional activity on Huggies diapers contributed two points of growth.

North America organic sales were off approximately 5% and selling prices increased 2%, mostly from sheet count reductions and Cottonelle bath tissue in the first quarter to improve net realized revenue. Product mix was also up two points in the quarter. Sales volumes declined 9% were impacted by the sheet count reductions at Cottonelle, consumer trade down in paper towels and competitive promotional activity.
Expect better volume performance in the back half of the year, taking into account the timing of marketing and promotional activity and the fact that the volume impact of count reduction should fade over time.
Switching to Europe, consumer tissue organic sales were down about 3% in a continued difficult environment. Sales volumes were down 2% and product mix was off an additional point. For K-C International, consumer tissue organic sales have increased more than 4%, driven by higher net selling prices.
The overall impact from Venezuela was roughly a point negative on sales volumes and one point positive on net selling prices. These impacts were more significant than our previous expectations. Going forward, in the near term they are assuming a continued challenging environment and so Venezuela is a factor that’s contributing to our updated organic growth assumptions which are included in our news release.
