Client portfolios include investment-grade fixed income, derivative overlay, and equity investments. As of September 30, 2021, NISA managed $317 billion in physical assets and $174 billion in derivative notional value in separate account overlay portfolios.

NISA also maintains a charitable fund: NISA Charitable Fund’s mission is to promote equity in St. Louis among underserved populations by supporting organizations focused on creating systematic change in education, access to capital, and workforce development. We believe that improvement in these critical foundational areas can lead individuals toward greater financial independence with a multiplier effect that can change the trajectory of the next generation. We are a donor-advised fund established in April 2020 and funded by NISA Investment Advisors, LLC, with operational support by St. Louis Community Foundation.
