NEW YORK (Standard&Poor's CreditWire) Oct 15, 1999—Standard&Poor's today assigned its single-'A' rating to North Carolina Medical Care Commission's $22 million revenue bonds series 1999, issued for Southeastern Regional Medical Center. The bonds are scheduled to sell on November 1, 1999. The rating reflects hospital's: -- Strong market position as the sole community provider in its service area, -- Steady growth in business volumes, -- Consistently profitable operations resulting in above average 3.4 times(x) pro forma coverage, and -- Sound balance sheet. A higher rating is precluded by: -- Limited economic base with above-average unemployment rate, -- A vulnerable payor mix complement, and -- Potential reimbursement threats. The bond proceeds will reimburse the hospital for previous capital
