ALLIANCEBERNSTEIN NATIONAL MUNICIPAL INCOME FUND

# AllianceBernstein National Municipal Income Fund

This closed-end investment fund, launched in 2001 and managed by AllianceBernstein L.P., focuses exclusively on U.S. municipal fixed income securities. The fund invests primarily in investment-grade municipal bonds rated Baa/BBB or higher, which generate interest income exempt from federal taxation. The portfolio construction employs both quantitative and fundamental analysis methodologies to evaluate municipal credit quality and yield opportunities across the U.S. fixed income market.

The fund generates revenue through investment management fees charged on assets under management. As a closed-end fund structure, it raises capital through an initial public offering and trades on secondary markets rather than continuously issuing and redeeming shares. AllianceBernstein L.P., the investment manager, is headquartered in Nashville, Tennessee and serves as the primary revenue source driver through management fees and portfolio advisory services.

The fund maintains a geographic footprint across the United States municipal bond market, with no geographic restrictions on the municipal issuers in which it invests. As a specialist municipal income vehicle, the fund operates within the asset management industry, competing with other municipal bond funds and fixed income strategies focused on tax-exempt returns for investors in higher tax brackets.
