S&P Global Ratings assigned its'AA-'long-term rating to Mahoning County , Ohio's approximately $20.0 million general obligation (GO; limited-tax) series 2026 building improvement bonds. At the same time, we affirmed our'AA-'long-term rating on the county's existing GO debt. The outlook is stable. The series 2026 bonds, as well as the previously issued GO debt, are secured by the county's full faith credit and resources and an agreement to levy ad valorem property taxes within its share of its 10-mill limitation. We rate the limited-tax bonds based on our view of the county's general creditworthiness, given that ad valorem taxes are collected from the entire tax base and there are no limitations on the fungibility of resources available
