Sales Statistic Terminology Question

[nb720]

I'm working on project involved with people reporting on sales targets, etc. and I cannot find an answer to what a certain statistic means. Here's an example (example numbers):

Sales revenue 6 billion dollars (+0.5 billion dollars YoY), operating profit 9.5 billion dollars (+1.1 billion dollars YoY), U8% (+0.7% YoY), Adj. EBITA ratio 6%.

What is U here and what does it stand for?

Thank you for any and all help, as this is really getting to me. Google is understandably not helpful when trying to search for "U".

@nb720 Could it be a typo? On a qwerty keyboard U is at the top, near the number row

@quantumleap009 It was used in the same manner several times, so I don't think it was a typo.
