There's no rating here, and we don't judge whether the dividend will continue - that would be advice. Here are the figures income investors usually look at, and what each one means, so you can weigh it up yourself.
Figures are from the latest available data and can be distorted by one-off results. Past payments don't predict future ones, and a dividend can be cut at any time. This lays out the numbers to help you understand them - it is not a view on what will happen.
