Moody's Investors Service has affirmed the "Baa1" ratings on Grand Forks, N.D.-based Altru Health System's revenue bonds, affecting about $182 million of rated debt.
The rating affirmation was supported by a number of factors, including the system being the primary referral hospital for a large region and having a market share of approximately 75 percent in its primary service area.
The rating affirmation was also supported by Altru's affiliation with Rochester, Minn.-based Mayo Clinic.
The system also faces some challenges, which were considered for the rating affirmation, such as having a high debt load.
