Outlook

The Company updated their outlook for 2011. Based on today’s assessment, management anticipates that local currency sales growth in 2011 will be in the range of 6% to 7% and Adjusted EPS in the range of $7.70 to $7.80, an increase of 11% to 12%. This compares with previous 2011 guidance of Adjusted EPS in the range of $7.35 to $7.55. Adjusted EPS excludes purchased intangible amortization, discrete tax items, restructuring charges and other one-time items.

The Company stated that based on their assessment of market conditions today, management anticipates local currency sales growth in the first quarter 2011 will be in the range of 10% to 12% while Adjusted EPS will be in the range of $1.34 to $1.38, an increase of 19% to 22%.

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 have emerged from the economic downturn in a stronger competitive position. Many factors position us well for growth in 2011 and beyond. In particular, a meaningful percentage of our business is anchored in fast-growing emerging markets where we benefit from a long-standing substantial presence and strong market positions. In addition, our sophisticated marketing programs provide a real competitive advantage in our fragmented markets. Finally, our product pipeline is robust and we continue to reinforce our technology leadership via new product introductions. While we remain cautious on the global economy given the uncertainty that exists, I am confident in our ability to continue to execute on our strategies.”
