(Adds CEO comments in paragraphs 4-5, updates shares) Dec 19 (Reuters) - IT services provider Accenture forecast second-quarter revenue below Wall Street targets on Tuesday, anticipating cautious spending by clients as macroeconomic uncertainty remains an overhang. Analysts expect IT services expenditure to remain muted in the near term as businesses typically decide their annual budgets only after February. Accenture itself has pointed to slower budget-related decision-making, especially in tech and media companies. Accenture's revenue from the communications, media & technology industry group fell 10% in the first quarter, while sales from North America, the company's biggest market, fell 1%, to $7.56 billion. "We continued to see lower discretionary spend, which impacts our consulting type of work," CEO Julie Sweet told analysts in an earnings call. "If you look around the environment, there are not a lot of green shoots on the economic side."
