State Street Global Exchange today announced that California State Teachers Retirement System (CalSTRS) has chosen the GX Private Equity Index as its Private Equity Investment Policy Benchmark. CalSTRS is the nation’s second largest public pension fund with assets totaling approximately $189.1 billion as of June 30, 2014. CalSTRS has $21.8 billion in private equity assets, or about 11.5 percent of their total portfolio 1. CalSTRS has been using the GX Private Equity Index as an additional performance benchmark for market research and performance evaluation since 2007. “After seeking a better private equity benchmark for years, we have decided that State Street’s Private Equity benchmark has achieved enough mass and history to replace our own internal index,” said CalSTRS Chief Investment Officer Christopher Ailman. The GX Private Equity Index is an industry recognized benchmark for comparative analysis of private equity performance and includes a comprehensive data set dating back nearly three decades. The index is based on directly-sourced limited partnership data, which represents over $2 trillion of private equity investments and includes more than 2,300 funds, as of March 31, 2014.
