time charters for three of our vessels, two of which, the African Glory and
Asian Grace, include profit sharing arrangements. Our time charter coverage
is among the highest in the industry, providing cash flow stability and
protection against the volatile freight rate environment. We also benefit of
having five of our vessels on profit sharing arrangements that allow us to
participate in market upswings."
