(1) Average number of vessels is the number of vessels that constituted the Company's fleet for the relevant period, as measured by the sum of the number of days each vessel was a part of the Company's fleet during the relevant period divided by the number of calendar days in the relevant period.
(2) Ownership days are the total number of days in a period during which the vessels in a fleet have been owned. Ownership days are an indicator of the size of the Company's fleet over a period and affect both the amount of revenues and the amount of expenses that the Company recorded during a period.
(3) Available days are the number of ownership days less the aggregate number of days that vessels are off-hire due to major repairs, dry dockings or special or intermediate surveys. The shipping industry uses available days to measure the number of ownership days in a period during which vessels should be capable of generating revenues. During the quarter ended June 30, 2012, the Company incurred 26 off-hire days for vessel scheduled drydocking. During the six month period ended June 30, 2012, the Company incurred 39 off-hire days for vessel scheduled drydocking.
(4) Operating days are the number of available days in a period less the aggregate number of days that vessels are off-hire for any reason, including unforeseen circumstances. The shipping industry uses operating days to measure the aggregate number of days in a period during which vessels actually generate revenues.
(5) Fleet utilization is the percentage of time that our vessels were generating revenue, and is determined by dividing operating days by ownership days for the relevant period.
(6) Fleet utilization excluding drydocking off-hire days is calculated by dividing the number of the fleet's operating days during a period by the number of available days during that period. The shipping industry uses fleet utilization excluding drydocking off-hire days to measure a Company's efficiency in finding suitable employment for its vessels and excluding the amount of days that its vessels are off-hire for reasons such as scheduled repairs, vessel upgrades, or dry dockings or special or intermediate surveys.
(7) TCE rates are defined as our net revenues less voyage expenses during a period divided by the number of our operating days during the period, which is consistent with industry standards. Voyage expenses include port charges, bunker (fuel oil and diesel oil) expenses, canal charges and other commissions.
