There will be no increase in the dividend in the next four years.
I see almost zero scenarios where the dividend is increased. It will take another two years of strong operating results to have the current dividend be at a sub 50% of cash flow. With all the debt that we have, any additional cash flow generated should be targetted to decreasing the overall amount of debt and keep leverage from growing.
IMO, $1/year is it. I like it and keep holding. If the $1/year isn't enough to cover the risks that are present then you'll have to look elsewhere.
