This class will address three broad themes of impact investing today: 1) The evolution of impact investing from niche field to mainstream; 2) Exposure to a broad spectrum of impact investment strategies; 3) Learn the tools, models and frameworks behind impact investing. Each week, we bring into the classroom senior investment managers of leading sustainable and impact investment firms to illustrate how their strategies generate and deliver impact. The backbone of the class is an experiential team project that will invite students to create a financial vehicle (e.g. investment firm, fund or instrument) capable of fitting within an asset allocation of institutional investor portfolios (public equities, fixed income, hard assets, private equities, alternative assets, etc.) while delivering social & environmental impact. In some cases, these class projects have wound up coming to fruition and are in the market today." FINC-431 or equivalent (FINC-435 or FINC-440) may be taken concurrently to satisfy this prerequisite.
