Moody's Investors Service has assigned an "A3" rating to New Hyde Park, N.Y.-based Northwell Health's proposed $500 million of series 2016A bonds.
Moody's also affirmed the "A3" rating on $1.5 billion of Northwell's outstanding debt.
The rating assignment and affirmation are based on a number of factors, including Northwell's size, significant footprint across the New York metro market and track records of growth.
Northwell also faces several challenges, including sizable capital spending plans and large losses in its health plan due to Affordable Care Act risk adjustment program payments that are expected to continue through 2017.
The outlook is stable, reflecting Moody's Investors Service's expectation that Northwell's core business will continue to perform well.
