This bill amends the Small Business Investment Act of 1958 to encourage increased capital investment in socially and economically disadvantaged small businesses by modifying leverage limits for Small Business Investment Companies (SBICs). It aims to provide greater flexibility for SBICs to support these specific enterprises. The legislation directs the Administrator to exclude the cost basis of equity investments made by an SBIC in a socially and economically disadvantaged small business from the company's outstanding leverage calculation. This exclusion is capped at 50 percent of the SBIC's private capital, allowing SBICs to deploy more capital without exceeding their standard leverage limits. To benefit from these modified leverage limits, an SBIC must be licensed in the first fiscal year after enactment or any subsequent year and certify that at least 50 percent of its investments will target socially and economically disadvantaged small businesses. The bill also sets specific maximum outstanding leverage amounts for qualifying companies. These maximums are the lesser of 300 percent of private capital or $175,000,000 for a single company, and $250,000,000 for two or more companies under common control. These provisions are intended to stimulate economic growth and innovation within underserved small business sectors.
