Sales fell across nearly all of Colgate-Palmolive's (CL - Get Report) segments during the 2016 fiscal fourth quarter and the company sees further "uncertainty" in 2017. 

Colgate stock tumbled 6.59% to $63.74 late Friday morning after the consumer products company earlier today reported revenue that missed analysts' forecasts. The New York-based company's revenue slid 5.5% to $3.72 billion year-over-year, which fell short of Wall Street's projections of $3.86 billion.

Global unit volume slumped 5.5%, pricing increased 2.5% and foreign exchange was negative 1.5%, Colgate said. Adjusted earnings of 75 cents per share met analysts' expectations.

On a conference call with analysts, executives were cautious about the full year. "I think it is safe to say that 2016 has been a year of growing uncertainty filled with unpredictable and disruptive events, especially in the fourth quarter," CEO Ian Cook said on the call.

Cook said there was significant foreign exchange volatility following the U.S. election, unexpected demonetization in India and category slowdown in several of Colgate's key markets. In 2017, Cook expects continued uncertainty in global markets and foreign exchange volatility to remain challenging. 

Latin America net sales tumbled 10.5% during the most recent quarter. Unit volume decreased 16.5% with 9% higher pricing, while foreign exchange was negative 3.0%. The segment makes up 24% of company sales.

Sales in its Europe, Asia Pacific and Africa/Eurasia units fell by 7.5%, 4% and 1.5%, respectively. 

The European sales drop was driven by volume declines in France. "The sharpness of the slowdown was a surprise," Cook said, noting that French retailers had similar issues reflecting consumer purchasing weakness. 

North American sales, unit volume, pricing, foreign exchange and organic sales were flat compared to last year. In the U.S., volume growth in toothpaste was offset by declines in toothbrushes and liquid hand soap. The company saw strong volume growth in its Canadian business and for its Tom's of Maine natural brand. North America represents 21% of total sales.

The company's Hill's pet nutrition unit net sales increased 0.5% during the period. Unit volume fell 2.5% with 2.5% higher pricing, while foreign exchange was positive 0.5%. Volume declines in the U.S., Western Europe and Japan were partially offset by volume gains in the rest of Asia, Latin America, Russia and South Africa. The unit makes up 15% of sales.

Based on current spot rates, the company expects a low-single-digit net sales increase for 2017.
