But hospital officials are confident that their $290 million purchase of Rex Healthcare in Raleigh will reverse the reduced rating.
Bruce Gordon, an analyst for Moody's Investors Service, lowered his security rating of UNC Hospitals' $183 million of long-term debt by one level, decreasing the rating from Aa3, the third highest possible rating, to A1.
"What the rating tells investors is the likelihood their purchase of UNC Hospital bonds will be repaid," said Gordon.
But Gordon also said that even the decreased rating puts UNC Hospitals behind only about 12 percent of business firms that his agency rates. "The A1 rating tells (investors) there is still a high likelihood their investment will be returned," he said.
Gordon said his agency has been following the financial progress of UNC Hospitals since 1992 and made the recent rating after observing a steady decrease in the hospital's income.
"By far the most influential force was a four-year decline in UNC Hospitals' operating cash flow," he said.
Eric Munson, president and CEO of UNC Hospitals, said the decrease in income was due mostly to the recent Balanced Budget Act, which reduced Medicare reimbursement to hospitals. He said the hospital has lost a projected $70 million between 1998 and 2002 due to lost income from Medicare.
Gordon also said higher demand for qualified nurses depleted hospital funds, also contributing to the loss in income.
Such problems are common for hospitals across the country, said Gordon, who cited other examples of hospitals having their credit rating lowered. "We've downgraded far more hospitals than upgraded in the past three years," he said.
