S&P Global Ratings raised its long-term rating on the Oklahoma Development Finance Authority 's series 2018B tax-exempt fixed-rate bonds and series 2018C taxable fixed-rate bonds to ?BB+? from ?BB?. The bonds were issued for OU Medicine Inc. (OUMI), now doing business as OU Health. In addition, we raised our underlying rating (SPUR) on the insured maturities of the authority's series 2018B and 2018C bonds, also issued for OUMI, to ?BB+? from ?BB?. The outlook is stable. The upgrade reflects OU Health's improved and stabilized operating performance, which we anticipate will continue to support incremental growth of year-end unrestricted reserves, and sustained moderation of debt metrics. The higher rating further incorporates OU Health's leading, and growing, position within Oklahoma's health care
