Grupo Mexico, the Company’s parent and the majority indirect stockholder of the Company, and its affiliates provide various services to the Company. These services are primarily related to accounting, legal, tax, financial, treasury, human resources, price risk assessment and hedging, purchasing, procurement and logistics, sales and administrative and other support services. The Company pays Grupo Mexico for these services and expects to continue paying for these services in the future.

The Company’s Mexican operations paid fees for freight services provided by Ferrocarril Mexicano S.A de C.V., for construction services provided by Mexico Proyectos y Desarrollo S.A. de C.V. and its affiliates and for drilling services provided by Compania Perforadora Mexico S.A.P.I. de C.V. The three companies are subsidiaries of Grupo Mexico.

The Company’s Mexican operations purchased from Asarco scrap and other residual copper mineral, and from MGE power. Both companies are subsidiaries of Grupo Mexico.

The Company paid fees for engineering, construction and consulting services provided by subsidiaries of Mexico Proyectos y Desarrollos S.A. de C. V., a subsidiary of Grupo Mexico.

In 2005, the Company organized MGE, as a subsidiary of Minera Mexico, for the construction of two power plants to supply power to the Company’s Mexican operations. In May 2010, the Company’s Mexican operations granted a $350 million line of credit to MGE for the construction of the power plants. That line of credit was due on December 31, 2012 and carried an interest rate of 4.4%. In the first quarter of 2012, Controladora de Infraestructura Energetica Mexico, S. A. de C. V., an indirect subsidiary of Grupo Mexico, acquired 99.999% of MGE through a capital subscription of 1,928.6 million of Mexican pesos (approximately $150 million), reducing Minera Mexico’s participation to less than 0.001%. As consequence of this change in control, MGE became an indirect subsidiary of Grupo Mexico. Additionally, at the same time, MGE paid $150 million to the Company’s Mexican operations partially reducing the total debt. At December 31, 2012, the outstanding balance of $184.0 million was restructured as subordinated debt of MGE with an interest rate of 5.75%. MGE will repay its debt to the Company using a percentage of its profits until such time as the debt is satisfied. At March 31, 2014 the remaining balance of the debt was $161.2 million and was recorded as non-current related party receivable on the condensed consolidated balance sheet. Related to this loan the Company received $2.3 million of interest in the first quarter of 2014.

In 2012, the Company signed a power purchase agreement with MGE, whereby MGE will supply some of the Company’s Mexican operations with power through 2032. MGE completed construction of its first power plant in June 2013 and the second plant in the first quarter of 2014. MGE is currently waiting the authorization for interconnection with the Mexican electrical system to start operations in the second plant. MGE began supplying power to the Company in December 2013. It is expected that MGE will supply a portion of its power output to third-party energy users. See also Note 9 - Commitments and Contingencies, Other commitments.

In addition, the Company received fees for building rental and maintenance services provided to Mexico Proyectos y Desarrollos, S.A. de C.V. and its affiliates and to Perforadora Mexico S.A.P.I de C.V., and for natural gas and services provided to MGE, all subsidiaries of Grupo Mexico.
