Thomson Reuters buys Abacus

Thomson Reuters has said it is to buy tax-software firm Abacus Enterprise from Deloitte, in a deal expected to be worth around $45m (£27m). The group has snapped up the London firm, which supplies tax products to half the firms in the FTSE 100, as part of ongoing expansion of its professional services activities. Thomson Reuters bought Digita, which provides tax software to accountants, under a similar transaction.
