Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions TNCLP and TNGP have no employees. We have entered into several agreements with a subsidiary of CF Industries relating to the operation of our business and the sale of the fertilizer products produced at our Verdigris facility. We believe that each of these agreements is on terms that are fair and reasonable to us. General and Administrative Services and Product Offtake Agreement Pursuant to the Amendment to the General and Administrative Services and Product Offtake Agreement (the Services and Offtake Agreement), the Partnership sells all of its fertilizer products to an affiliate of the General Partner at prices based on market prices for the Partnership's fertilizer products as defined in the Services and Offtake Agreement. Title and risk of loss transfer to an affiliate of the General Partner as the product is shipped from the plant gate. The Services and Offtake Agreement is effective for annual terms starting as of January 1st and will be extended automatically for successive one-year terms unless terminated by one of the parties prior to renewal. Directly Incurred Charges Since we have no employees, we rely on employees from an affiliate of the General Partner to operate our Verdigris facility. As a result, the payroll, payroll-related expenses and benefits, such as health insurance and pension, incurred by an affiliate of the General Partner, are directly charged to us. Payroll, payroll-related expenses and other employee-related benefits directly charged to us for the three and six months ended June 30, 2015 were $6.5 million and $14.1 million, respectively, and for the three and six months ended June 30, 2014 were $5.9 million and $11.5 million, respectively. We report these expenses as services provided by affiliates of the General Partner in cost of goods sold. Allocated Charges CF Industries, together with its affiliates, also provides certain services to us under the Services and Offtake Agreement. These services include production planning, manufacturing management, logistics, procurement, accounting, legal, risk management, investor relations and other general and administrative functions. Allocated expenses charged to us for the three and six months ended June 30, 2015 were $4.0 million and $7.9 million, respectively, and for the three and six months ended June 30, 2014 were $3.8 million and $7.7 million, respectively. We report these expenses as selling, general and administrative services provided by affiliates of the General Partner. Amounts Due to/from Affiliates of the General Partner We receive cash and make expenditures directly from our cash accounts. Because we sell our products to and receive payroll and other related services from affiliates of the General Partner, the affiliates of the General Partner continue to be both debtors and creditors to us. As of June 30, 2015 and December 31, 2014, we had a net balance due from affiliates of the General Partner of $21.4 million and $21.0 million, respectively. Spare Parts Sharing Agreement Affiliates of CF Industries own and operate nitrogen fertilizer complexes that utilize some equipment that is similar to equipment at our Verdigris nitrogen complex. Each of the various manufacturing complexes maintains spare parts for use in its facilities. In the event that an unplanned need arises and to help minimize manufacturing downtime, we have entered into a spare parts sharing agreement that permits spare parts to be shared among the manufacturing complexes from time to time. Parts that are borrowed from another complex under the agreement are either refurbished and returned to the lender or replaced. Leases We entered into an amended and restated lease with an affiliate of the General Partner under which the ammonia assets in our terminal in Blair, Nebraska are leased by the affiliate. The lease is effective for a five-year term ending on December 31, 2018, and the affiliate of the General Partner has options to renew for three additional five-year terms. The quarterly lease payment is $100,000, subject to an annual inflation adjustment, and additional rent will be paid equal to all costs, expenses, and obligations incurred by the affiliate of the General Partner related to the use, occupancy and operation of the terminal. We also have leased certain of our rail cars to an affiliate of the General Partner for quarterly market-based rental payments of $3,600 per car. This lease was effective initially for a one-year term and is extended automatically for successive one-year terms unless terminated by either party thereto prior to renewal. We recognized rental income for the three and six months ended June 30, 2015 and 2014 of $0.2 million and $0.3 million, respectively.
