They have extra cash on the balance sheet and want to distribute it, so even though they are not earning the dividend it is safe. If you wanted to go by a cash basis, they could probably fund $1/yr in dividends. Some of their expenses are non-cash such as stock options and depreciation.
Having said all that, this qtr is off to a record start. If you go back and read maybe the last 10 threads you will see that coin certs are off to a record start and they should actually generate cash even after the dividend this qtr.
I would thus conclude that the dividend is safe through this year but they will probably reevaluate every year as every company does.
