The Goldman Sachs Group, Inc. reported on Monday that it has sold its credit indices to the International Index Co.

Terms of the transaction were not disclosed. Although the firms announced that Goldman Sachs will become a shareholding member of IIC as a result of this transaction.

Following a brief transition period, the indices currently known as the GS $ InvesTop Index and the GS $ HYTop Index will be administered by IIC under the names iBoxx $ Liquid Investment Grade Index and iBoxx $ Liquid High Yield Index. The companies expect to complete the transition by November 1.

Brad Levy, a Goldman Sachs managing director, said, “We are very excited to become a member of IIC. The contribution of our existing US-based cash indices is a great addition to an already robust suite of IIC products. We look forward to working with IIC to further develop the global credit index market.”

David Mark, IIC’s CEO, said, “Our independent, multiple-contributor priced indices have been adopted as market standard in Europe, and with the addition of Goldman Sachs as a price provider in the US market, we expect our credit indices to appeal to a broader set of clients. The indices we are taking over have been designed to provide a superior basis for exchange traded funds and structured products.”

IIC is owned by ABN Amro, Barclays Capital, BNP Paribas, Deutsche Bank, Deutsche Borse, Dresdner Kleinwort, Goldman Sachs, HSBC, JP Morgan, Morgan Stanley and UBS.
