Second Quarter Results

Olivier Filliol, President and Chief Executive Officer, stated, “Sales growth in the quarter was better than expected with strong results in most product lines and geographies. We were particularly pleased with the solid performance in all regions. Strong operating leverage drove further gross margin expansion and we are pleased with our excellent growth in operating profit and EPS.”

EPS was $1.49, compared with the prior-year amount of $0.81. Adjusted EPS was $1.55, an increase of 32% over the prior-year amount of $1.17.

Sales were $468.5 million, a 16% increase in local currency sales, compared with $407.4 million in the prior year. Reported sales growth was 15%, which included a negative 1% currency impact. By region, local currency sales increased 10% in Europe, 15% in the Americas and 27% in Asia / Rest of the World. Adjusted operating income amounted to $79.9 million, a 30% increase from the prior-year amount of $61.7 million. Adjusted operating income is a non-GAAP measure, and a reconciliation to earnings before taxes is provided in the attached schedules.

Cash flow from operations was $74.8 million, compared with $74.0 million in 2009.

Six-Month Results

EPS was $2.59, compared with the prior-year amount of $1.81. Adjusted EPS was $2.68, a 26% increase over the prior-year amount of $2.12.

Sales were $885.2 million, an 11% increase in local currency sales, compared with $781.5 million in the prior year. Reported sales growth was 13%, which included a 2% currency benefit. By region, local currency sales increased 4% in Europe, 13% in the Americas and 21% in Asia / Rest of the World.

Cash flow from operations was $119.3 million, compared with $108.9 million in 2009.

Outlook

Based on today’s assessment, management anticipates that local currency sales growth in 2010 will be in the range of 8% to 9% and Adjusted EPS will be in the range of $6.35 to $6.45, an increase of 14% to 16%. This compares with previous guidance of Adjusted EPS in the range of $6.26 to $6.36. Adjusted EPS excludes purchased intangible amortization, discrete tax items, restructuring charges and other one-time items.

For the third quarter 2010, the Company anticipates local currency sales growth to be in the range of 8% to 10% and Adjusted EPS in the range of $1.52 to $1.57, an increase of 12% to 15%.

While the Company has provided an outlook for Adjusted EPS, it has not provided an outlook for EPS. EPS guidance would require an estimate of non-recurring items, which are not yet known.

Conclusion

Filliol concluded, “We are encouraged by the further improvement in business momentum during the second quarter. Our sales growth is clearly benefiting from the investments in marketing programs, product development and emerging markets distribution that we continued to make during the downturn. Although our current outlook for the third quarter is solid, we remain cautious given the uncertainty in the global economy.”
