S&P Global Ratings placed the BB-minus rating of Live Nation Entertainment Inc. LYV, -2.68% on review for a possible downgrade on Monday, as more and more live events around the globe are canceled because of the coronavirus. "While the extent and duration of the impact on the live events industry are uncertain, we believe Live Nation Entertainment Inc.'s operating performance could be hurt by the growing number of postponed events, lower-than-expected attendance, or any future cancelations," the rating agency said in a statement. The disruptions could effect the company's operating performance and keep leverage above S&P's 5 times leverage threshold for the BB-minus rating, said the statement. Live Nation's shares were down 17% premarket and are down 32% in the last 12 months, while the S&P 500 SPX, -1.11% has fallen 45.
