The Partnership's distributable cash flow for the three months ended December 31, 2010 was $22.2 million and for the year ended December 31, 2010 was $65.5 million. Distributable cash flow is a non-GAAP financial measure which is explained in greater detail below under "Use of Non-GAAP Financial Information." The Partnership has also included below a table entitled "Distributable Cash Flow" in order to show the components of this non-GAAP financial measure and its reconciliation to the most comparable GAAP measurement.
Ruben Martin, President and Chief Executive Officer of Martin Midstream GP LLC, the general partner of the Partnership, said: "I am pleased with the Partnership's fourth quarter and year end 2010 performance. The fourth quarter 2010 was our best quarter during the year in terms of cash flow generation as we achieved a strong distribution coverage ratio of 1.53 times. That put us in a position to increase our most recent distribution to unitholders for the first time in nine quarters. Further, for the year ended 2010, all four of our operating segments met or exceeded planned performance giving us a solid distribution coverage ratio of 1.16 times.
During the fourth quarter, our sulfur services segment rebounded from the seasonal weakness we typically see in the third quarter. We saw sulfur experience a solid pricing recovery based on high demand across agricultural markets both foreign and domestic. We expect this demand for our sulfur and sulfur-based fertilizer products to remain strong into 2011. Our Marine Transportation segment was also strong during the fourth quarter. Our inland fleet continues to operate near full utilization; and day rate pricing for certain products we move has recently increased. Given the current condition of the oil refining business we feel good about our inland fleet for 2011. On the offshore side, our work on the Macondo disaster recovery is now complete and thus we have two offshore vessels that will seek opportunities in the spot market.
