The purpose of this legislation, known as the "Investing in All of America Act of 2025," is to support small businesses, particularly those located in rural or low-income areas, as well as small businesses involved in critical technology sectors. The act aims to encourage investment in these areas by allowing certain investments to be excluded from the limits on financial leverage that small business investment companies can use. Key provisions of the act include changes to how leverage limits are calculated for small business investment companies.
