Moody's Investors Service affirmed its 'Aa1/VMIG 1' ratings on Reno, Nev.-based Renown Health's outstanding revenue bonds.
The affirmation affects the system's Series 2008A and 2008B bonds, which are supported by a recently-issued substitute letter of credit from Wells Fargo Bank.
Renown will draw on the letter of credit to make timely payment of the principal and interest to the bondholder.
