Continued growth in the number of exchange-traded funds (ETFs) based on S&P indices and a 41.1% year-over-year increase in assets under management in these ETFs contributed to a strong performance by the Benchmarks Group in the second quarter. Reflecting the recovery in global markets and an inflow of new funds from investors, assets under management in ETFs linked to S&P indices grew to $325.3 billion at the end of the second quarter. Sixteen new exchange-traded funds using S&P indices were launched in the second quarter, bringing the total currently based on S&P indices to 349. At the end of 2010, there were 301. The Benchmarks Group also benefited from growth in data sales and the creation and licensing of a dozen new custom indices for major clients in financial markets.
