I personally don't understand the valuation, but there certainly seems to be demand for both their bonds and equity. Here's another Bloomberg article with info on their recent $700mm bond sale in April and a couple of interesting excerpts:
> The company had initially planned to sell $500 million, and then received orders of about five times that amount.
> Moody’s Investors Service rated the notes Caa1, seven steps into junk. S&P Global Ratings rated them three steps higher than Moody’s at B+, while Fitch gave them a rating of BB-, four steps higher than Moody’s.
