MediaNews Group, the Denver-based chain that owns several dailies in the Bay Area, has told Standard & Poors it no longer wants the firm to rate its ability to repay an estimated $962 million in debt, the Denver Business Journal reports.

Last April, MNG stopped releasing its financial information to the public, such as its earnings or executive compensation. [Also see E&P’s take on this.]
