Sony India, a unit of Japan's Sony Corp. , expects sales growth in the current financial year to slow down to 35 per cent compared with a 46 per cent rise a year ago, a top official told reporters on Tuesday.

The revenue growth is expected to slow down due to the current macroeconomic environment, including rising interest rates and inflation, resulting in customers cutting back on purchases, Masaru Tamagawa, managing director at Sony India said.

The firm has earmarked advertising and promotional expenditure of 3.6-billion rupees ($80.9-million U.S.) for the current financial year ending March 2012.
