(6) Operational off-hire days. We define operational off-hire days as days associated with unscheduled repairs or other off-hire time related to the operation of the vessels.
(7) Voyage days. We define voyage days as the total number of days in a period during which each vessel in our fleet was in our possession net of commercial and operational off-hire days. We use voyage days to measure the number of days in a period during which vessels actually generate revenues.
(8) Fleet utilization. We calculate fleet utilization by dividing the number of our voyage days during a period by the number of our available days during that period. We use fleet utilization to measure a company's efficiency in finding suitable employment for its vessels and minimizing the amount of days that its vessels are off-hire for reasons such as unscheduled repairs or days waiting to find employment.
(9) Fleet utilization, commercial. We calculate commercial fleet utilization by dividing our available days net of commercial off-hire days during a period by our available days during that period.
(10) Fleet utilization, operational. We calculate operational fleet utilization by dividing our available days net of operational off-hire days during a period by our available days during that period.
(11) Time charter equivalent, or TCE, is a measure of the average daily revenue performance of a vessel on a per voyage basis. Our method of calculating TCE is consistent with industry standards and is determined by dividing revenue generated from voyage charters net of voyage expenses by voyage days for the relevant time period. Voyage expenses primarily consist of port, canal and fuel costs that are unique to a particular voyage, which would otherwise be paid by the charterer under a time charter contract, as well as commissions. TCE is a standard shipping industry performance measure used primarily to compare period-to-period changes in a shipping company's performance despite changes in the mix of charter types (i.e., spot voyage charters, time charters and bareboat charters) under which the vessels may be employed between the periods.
(12) Daily vessel operating expenses, which includes crew costs, provisions, deck and engine stores, lubricating oil, insurance, maintenance and repairs and management fees are calculated by dividing vessel operating expenses by fleet calendar days for the relevant time period. Drydocking expenses are reported separately.
(13) Daily general and administrative expense is calculated by dividing general and administrative expense by fleet calendar days for the relevant time period.
(14) Total vessel operating expenses, or TVOE, is a measure of our total expenses associated with operating our vessels. TVOE is the sum of vessel operating expenses excluding drydocking expenses and general and administrative expenses. Daily TVOE is calculated by dividing TVOE by fleet calendar days for the relevant time period.
(15) Drydocking expenses, which include expenses during drydockings that would have been capitalized and amortized under the deferral method divided by the fleet calendar days for the relevant period. Drydocking expenses could vary substantially from period to period depending on how many vessels underwent drydocking during the period.
