Outlook

The Company updated its outlook for 2016 and noted that forecasting remains challenging. In particular, weak demand in certain emerging markets remains.

Based on today’s assessment, management anticipates that local currency sales growth in 2016 will be in the range of 3% to 4% and Adjusted EPS is forecasted to be in the range of $14.10 to $14.30, an increase of 9% to 11%.

For the first quarter 2016, management anticipates that local currency sales growth will be approximately 4% and Adjusted EPS is forecasted to be in the range of $2.40 to $2.45, an increase of 7% to 9%.

Adjusted EPS excludes purchased intangible amortization, discrete tax items, restructuring charges and other one-time items. While the Company has provided an outlook for Adjusted EPS, it has not provided an outlook for EPS as it would require an estimate of non-recurring items, which are not yet known.

Conclusion

Filliol concluded, "Despite considerable market weakness in China, Brazil and Russia and significant currency headwinds, we achieved good financial results in the quarter and for full year 2015. Strong execution of our margin enhancement and productivity improvement programs were key contributors to our performance. We continue to gain share through expanded field resources, exciting new products and proven sales and marketing initiatives. Equally important, we are making investments for long-term growth. While we remain cautious on the global economy, we believe we can continue to generate above market growth in 2016 and beyond.”
