The bill establishes formal processes for the MBDA Business Center Program and the MBDA Rural Business Center Program through which business centers provide programs and services to support MBEs. The bill also establishes new initiatives to promote economic resiliency for minority businesses, including (1) an annual forum to review problems and programs relating to capital formation by MBEs, (2) a study and report on alternative financing solutions for MBEs, and (3) entrepreneurship education grants for certain institutions of higher education to develop and implement entrepreneurship curricula. Further, the bill establishes grants for certain nonprofit organizations that provide services to MBEs as one of their primary activities.
