Fitch Ratings assigned its "A" issuer default rating to Scottsdale, Ariz.-based HonorHealth.
Concurrently, Fitch affirmed its "A" rating on HonorHealth's outstanding revenue bonds, affecting about $510.3 million of debt.
The assignment and affirmation are a result of several factors, including the health system's leading market position, favorable service area and strong unrestricted liquidity. Fitch acknowledged that HonorHealth operated at a loss in fiscal year 2017, but the rating agency expects the health system to improve its operating performance in fiscal year 2018.
The outlook is stable.
