SAN FRANCISCO (S&P Global Ratings) Feb. 23, 2017--S&P Global Ratings assigned its 'BBB-' long-term rating to California School Finance Authority's charter school revenue bonds series 2017A (tax-exempt) and 2017B (taxable), issued for Granada Hills Charter High School Obligated Group (GHCHS). The outlook is stable. "We assessed GHCHS's enterprise profile as adequate, characterized by steady enrollment, solid demand with a sufficient waiting list, good academics, and a proactive management team," said S&P Global Ratings Robert Tu. "We assessed GHCHS's financial profile as adequate, with a large operating base and very low maximum annual debt service burden, offset by a weak pro-forma lease adjusted maximum annual debt service coverage, and below average liquidity compared to similarly rated peers," Mr. Tu added.
