BlackRock said on Thursday that it saw the highest investor inflows in its history during 2014, but earnings fell more than 3% in the most recent quarter as performance fees fell.

BlackRock, the world's largest asset manager, also raised its dividend to $2.18 a share from $1.93, while boosting its share-buyback programme by 6 million shares under its existing plan for a total of as many as 9.4 million shares.
