The approach that I thought would be best would be to take a weighted average of Price/DWT for 4 closely comparable ships. Upon taking an average of these Price/DWT factors‚ I multiplied this value by the 172‚000 weight of the Bet Performer to get its worth. I also considered the Capsize index in pricing the Bet Performer off of its comparable. The max Index value was now 12‚479 in May 2008‚ so solving for an index factor to adjust my 76.65 million result‚ yields a selling price of $135.36 million
