The Standard & Poor’s upgrade for Sirius XM moves their credit rating one notch out of speculative territory, from “Triple C+” to “B-minus.” The Wall Street Journal says the upgrade comes after Sirius XM announced a successful new debt refinancing, which raised $250 million, with a portion of that money being used to pay back part of Liberty Media’s $530 million loan. That’s the early-2009 loan which kept Sirius XM out of bankruptcy or other dire straits. The S&P upgrade also cites “increased comfort” with Sirius XM’s near-term liquidity.
