NEW YORK (AP) -- Nielsen Holdings N.V. lowered the upper-end of its full-year revenue guidance on Wednesday.
The company, which measures what consumers watch and buy, attributed the revision to "changes in operating conditions" for its buy business outside the U.S. The buy business tracks information on consumer shopping, behaviors and other measures that it sells to businesses, primarily to makers of consumer packaged good.
Nielsen declined to provide further detail on what the changes in operating conditions are.
The company now expects revenue growth of 5 to 6 percent over 2011, versus its prior guidance of 5 to 7 percent. Both measures exclude the impact of currency fluctuations.
The new guidance suggests the company would generate revenue of roughly $5.81 billion to $5.92 billion for 2012.
Nielson stood by its earnings expectations of $1.76 to $1.82 per share for the year.
Analysts polled by FactSet expect the company to earn $1.79 per share on revenue of $5.76 billion, on average.
Shares of the information company fell 24 cents to $27.54 in afternoon trading. The stock has traded between $24.38 and $31.83 over the past year.
