Accounting for Revenue and Expenses: Revenues are generated from bareboat charter, time charter, voyage charter agreements and pool arrangements. A bareboat charter is a contract in which the vessel owner provides the vessel to the charterer for a fixed period of time at a specified daily rate, which is generally payable monthly in advance, and the customer generally assumes all risks and costs of operation during the charter term. A time charter is a contract for the use of a vessel for a specific period of time and a specified daily charter hire rate, which is generally payable monthly in advance. Profit sharing represents the excess between an agreed daily base rate and the actual rate generated by the vessel every quarter, if any, and is settled and recorded on a quarterly basis. Under a voyage charter, revenue, including demurrage and associated voyage costs, with the exception of port expenses which are recorded as incurred, are recognized on a proportionate performance method over the duration of the voyage. A voyage is deemed to commence upon the latest between the completion of discharge of the vessel's previous cargo and the charter party date of the current voyage and is deemed to end upon the completion of discharge of the current cargo. Demurrage income represents payments by the charterer to the Company when loading or discharging time exceeded the stipulated time in the voyage charter. Vessel operating expenses are expensed as incurred. Unearned revenue represents cash received prior to year-end related to revenue applicable to periods after December 31 of each year. Under a pool arrangement, the pool charters-in a vessel on a time charter basis but the daily charter hire is not fixed but it depends on the total return that the pool is able to achieve by operating all its vessels in the spot market. When vessels are acquired with time charters attached and the rates on such charters are below market on the acquisition date, the Company allocates the total cost between the vessel and the fair value
