Unearned revenue represents cash received prior to year-end related to revenue applicable to periods after December 31 When vessels are acquired with time charters attached and the rates on such charters are below or above market on the acquisition date, the Company allocates the total cost between the vessel and the fair value of below market time charter based on the relative fair values of the vessel and the liability or asset acquired. The fair value of the attached time charter is computed as the present value of the difference between the contractual amount to be received over the term of the time charter and management’s estimates of the market time charter rate at the time of acquisition. The fair value of below or above market time charter is recognized as an intangible liability or asset respectively and is amortized over the remaining period of the time charter as an increase or decrease to revenues. The Company pays commissions to ship brokers associated with arranging the Company’s charters. These commissions are recognized over the related charter period and are included in voyage expenses.
