"The ratings reflect our view of NMHC's strong operations for the first nine months of fiscal 2016," said S&P analyst Brian Williamson.
The outlook is stable, reflecting S&P's opinion that NMHC will maintain strong operations as its leadership continues to maintain the expense base while investing in other facilities and affiliations.
