Hey there,
Well, for starters even though NWH has managed to not cut the distribution, I'd be remiss to say it was safe. The company is dealing with high debt loads and high payout ratios. A few months ago we did a newsletter using NWH as an example of a high-yielding distribution. Since that article has been written, key ratios and debt loads have actually gotten worse, so you can read this article to get an idea of our thoughts.

You'll see that we don't exactly have confidence in the current state of the dividend and as mentioned, the situation has gotten worse. With this in mind, if you are buying it for a high yield, be prepared for that distribution to be cut. Not saying it will but it certainly isn't one of the best covered in the space.
