ImpactAssets on Tuesday released its ImpactAssets 50 2019 (IA 50) database of 50 private-capital fund managers who strive to deliver social and environmental impact in tandem with financial returns.

The managers listed in the eighth-annual edition of the IA 50 database oversee an estimated $28.5 billion in assets focused on creating measurable and positive impact, according to ImpactAssets, a Bethesda, Md.-based nonprofit financial services firm built on the concept of juicing the flow of capital into investments delivering financial, social and environmental returns.

The IA 50 is an online database that enables its targeted market of impact investors, family offices, financial advisors and institutional investors to sort and filter across a range of asset classes such as debt, private equity and real assets, along with other criteria such as geographies, size of funds and themes.

In a press release announcing this year’s IA 50, ImpactAssets noted that more than 75 percent of the fund managers in the database target market-rate or above market-rate returns, and 94 percent have delivered either in line or above their initial target returns.

In addition, the IA 50 is now aligned with the U.N. Sustainable Development Goals, with the primary SDG listed for each fund manager in the database.

Among other aspects highlighted in this year’s IA 50 is that 66 percent of the managers in the database have been in business for at least 10 years.

Meanwhile, 25 percent or more of the investment professionals at these firms are women and/or from under-represented groups, and that half of these firms have teams with 50 percent or more women and other under-represented groups, which ImpactAssets claims is a significantly higher percentage than investment industry averages.
