Thank you, Assi. Good morning. For the first quarter of 2014, Delek Logistics reported net income attributable to all partners of $14.7 million or $0.59 per diluted limited partner unit, compared to income attributable to all partners of $12.2 million or $0.50 per diluted limited partner unit in the prior year period. Improved performance compared to the first quarter of 2013 was driven by several acquisitions completed during the past year. As a result, contribution margin increased to $22.8 million in Q1 of 2014 from $17.2 million in the prior year period. In addition to acquisitions, strong results in the first quarter of 2014 were benefited from higher volumes on the SALA Gathering System and strong margins in our West Texas wholesale business.
Now, I will spend a few minutes discussing our 2 reporting segments. First quarter 2014 contribution margin in our Pipeline and Transportation segment improved to $12.8 million on a year-over-year basis compared to $8.9 million in first quarter of 2013. The improvement was primarily attributed to storage fees from the Tyler tank farm purchased in July of 2013, the North Little Rock terminal acquired in October of 2013 and the El Dorado tank farm acquired in February 2014.
During the quarter, volumes on the Lion Pipeline System declined year-over-year due to downtime associated with planned turnaround work at Delek US' El Dorado refinery. The financial effect of lower volumes was limited by fees generated under the minimum volume commitments on this system. Throughput on our SALA Gathering System benefited from Delek US' ability to store crude oil, while its El Dorado refinery was undergoing a turnaround in January and February.
Contribution margin in our Wholesale Marketing and Terminalling segment was $10 million in the first quarter of 2014 compared to $8.3 million in the first quarter of 2013. Contribution from the Tyler, Texas terminal; the addition of the North Little Rock, Arkansas terminal; and the El Dorado, Arkansas terminal were the primary factors contributing to the improvement versus Q1 of '13.
During the first quarter, volume per day increased under our East Texas Marketing Agreement to approximately 62,400 barrels per day from approximately 53,100 barrels per day in the first quarter of 2013. This was primarily due to maintenance work at Delek US' Tyler, Texas refinery during the first quarter of 2013 that reduced sales volumes during that period.
In our West Texas wholesale business, volume was 15,999 barrels per day in Q1 of 14 compared to 16,555 barrels per day in the prior year period. This decline is primarily due to lower volume at the Abilene, Texas terminal due to maintenance work in February and March of 2014. The gross margin was $3.57 per barrel in Q1 of '14 compared to $3.69 per barrel in Q1 of '13. The margin per barrel in the first quarter included approximately $1.1 million or $0.75 per barrel from RINs generated in our ongoing ethanol blending activities during Q1 of 2014. This compares to a gross margin that included $1.8 million or $1.18 per barrel from RINs in the first quarter of '13. A strong wholesale margin helped offset the lower RINs benefit on a year-over-year basis. Also, the gross margin per barrel in the first quarter of 2014 improved sequentially from $1.24 per barrel in the fourth quarter of 2013. As of March 31, 2014, Delek Logistics had a cash balance of approximately $4.1 million and total debt was $260.5 million. We ended the quarter with approximately $126 million of unused availability under our $400 million credit facility. Capital expenditures were approximately $800,000 in Q1 of '14, which included no reimbursement under our Omnibus agreement with Delek US.
Maintenance capital expenditures were approximately $700,000 and growth related projects were approximately $100,000. Total capital expenditures for 2014 are expected to be $18.5 million compared to $5.1 million in 2013. This increase from 2013 is associated with the acquisitions completed over the past year and additional capital expenditures for growth. The decrease from our previous estimate of $20.4 million in 2014 is related to timing of growth-related projects. The 2014 capital expenditure amount consist of $9.5 million of maintenance, $9 million of growth-related projects. Of these amounts, approximately $6.9 million should be reimbursed under our agreement with Delek US in 2014.
With that, I will turn the call over to Uzi for his closing comments.
