In the largest private equity deal so far this year, Interactive Data Corporation (IDC), a provider of financial market data, has agreed to be taken over by private equity firms Warburg Pincus and Silver Lake Management for $3.4 billion.

IDC’s single largest shareholder, publishing company Pearson plc, will get $2 billion for its 61 percent stake. IDC shareholders will be paid $33.86 per share, a 32.9 percent premium over IDC’s closing price on Jan. 14, 2010, the last trading day before the company announced it was considering “strategic alternatives.”
