No, that's not an issue, because first of all, the risk is very low, so you know you can be insured for that specific risk. Of course incrementally you have to pay more, but because it's something that is marginal, it doesn't double your insurance costs. It's a kind of marginal increase of your insurance cost, especially when it's something that is under an international convention, because the whole fleet, internationally, is covered, and under this convention the risk is also shared with the receivers of HNS.
