Subdued transactional revenues have resulted in Computershare (ASX:CPU) experiencing an overall drop in revenue of 3.8 per cent to $US781 million for the half year ended 31 December 2010, a figure the Australian investor services company claims is in line with company expectations.

Australian investor services giant Computershare this week revealed that it had rebuilt its most highly trafficked sites on Microsoft's Azure cloud computing platform, sending them live in the first week of August.
