Sean M. Healey
Thanks, Ally. Good morning, everyone. With Economic earnings per share of $1.58 for the first quarter, AMG is off to an excellent start in 2012 with strong execution across all aspects of our growth strategy, including 2 new Affiliate investments, strong performance of our products and outstanding organic growth from net client cash flows bringing our total pro forma assets under management to just under $400 billion.
This was our eighth consecutive quarter of strong positive flows with over $7 billion in net inflows and $24 billion in the past 12 months. Our net inflows into a broad array of return-oriented strategies are particularly notable in a period were industry flows are being concentrated in fixed income and passive products. We continue to benefit from our strategic focus on highly attractive product areas, especially global and emerging market equities and alternatives, as well as the under -- the ongoing success of our global distribution strategy.
Affiliates such as global and emerging market equity managers: Tweedy, Browne, Genesis, Harding Loevner, Trilogy and Artemis; and alternative firms: Pantheon, AQR, BlueMountain and ValueAct are all leaders in their respective disciplines, with outstanding track records of investment performance and prospects for continued organic growth. Our results reflect the strong -- the continued strong execution of our global distribution strategy as our Affiliates are winning new business and market share through both affiliate level marketing efforts as well as by leveraging our global platform, which enhances the presence of our Affiliates across channels and geographies.
Given the ongoing success of our strategy, we continue to build out our institutional and retail platforms worldwide through the opening of new offices and the addition of key personnel in existing coverage regions. As investor risk appetite inevitably returns around the world, our Affiliates are uniquely positioned to benefit, and we're seeing numerous opportunities for continued strong organic growth ahead.
