S&P Global Ratings assigned its 'AA' long-term rating to Indianapolis Local Public Improvement Bond Bank, Ind.'s series 2016B refunding bonds, issued on behalf of the city of Indianapolis. The rating is based on a pledge of special benefits ad valorem property taxes levied on all taxable property in the city's Redevelopment District, which is coterminous with the city. At the same time, we affirmed our 'AA' rating on existing ad valorem tax-secured debt issued by and on behalf of the city, as well as our 'AA-' rating on its lease-backed debt. The city's lease-backed debt is subject to annual appropriation, and we set this rating one notch below the general obligation (GO) equivalent ad valorem tax rating to reflect this
