A comparison of current carrying values to anticipated future operating cash flows, expectations with respect to future operations and other relevant factors, including judgements and assumptions regarding expected future charter rates and expected future utilization rates, are also considered in this determination. When impairment indicators are present, the estimates and assumptions regarding expected cash flows require considerable judgment and are based upon historical experience, financial forecasts and industry trends and conditions and reflect management’s assumptions and judgements. Future cash flow assumptions also require estimates regarding the remaining useful lives of the vessels and capitalized drydocking costs. When discounted cash flows are required, assumptions are made regarding the discount rate applied to the estimated future cash flows. </div></div></div>
