Clients added a net $87.8 billion in investor money, more than triple what it gathered in the prior three months and the highest amount ever raised in a quarter, the New York-based company said today. The amount includes $44 billion that went into BlackRock's iShares ETFs. "The most important thing I can tell you about our year was obviously that the magnitude of flows was huge," Chief Executive Officer Laurence D. Fink, 62, said in a telephone interview today. The firm, which is targeting annual growth in assets of 5 percent, benefited as investors made record use of exchange- traded funds, and after Bill Gross in a surprise move quit Pimco at the end of September, which prompted record outflows at the bond firm. Investors poured $48 billion into BlackRock's fixed income funds in the quarter. BlackRock shares rose 0.5 percent to $347.51 at 10:25 a.m. in New York.
