enter into a 20-year Implementation Agreement with the SA DOE that creates an obligation for the power plant to satisfy its identified economic development objectives.
Under the REIPPP program, the South African government guarantees the payment obligations of Eskom under the PPAs entered into with renewable energy producers in defined circumstances. These guarantee arrangements, along with the support package adopted by the National Treasury on September 14, 2014, has facilitated private sector development as financing sources and investors have been willing to accept sovereign country risk without requiring political risk insurance, as would be the case in virtually every other African jurisdiction. Based on the sovereign guarantee and support package, we believe that Eskom will be a low risk offtake counterparty purchaser with a similar credit profile to our other customers. In addition, an accelerated depreciation allowance (50% in the first year of use, 30% in the second, and 20% in the third) applies to the cost of selected movable machinery and articles used in the construction of the solar and wind farms.
Financial Information about Segments
We have two reportable segments, solar and wind. These segments comprise the Company’s entire portfolio of power plants and are determined based on the management approach, which means that the scope of the reportable segments is derived from the internal reporting used by management for making decisions and assessing performance. Corporate expenses include general and administrative expenses, acquisition costs, formation and offering related fees and expenses, interest expense on corporate indebtedness, stock-based compensation and depreciation, accretion and amortization expense. All operating revenues, net for the year ended December 31, 2016 were earned by our reportable segments from external customers in Brazil, China, India, Malaysia, South Africa, Thailand and Uruguay, all operating revenues for the year ended December 31, 2015 were earned by our reportable segments from external customers in Brazil, China, India, Malaysia, South Africa and Thailand and all operating revenues for the year ended December 31, 2014 were earned by our reportable segments from external customers in China, India, Malaysia, South Africa and Thailand.
For the year ended December 31, 2016, Camara de Comercializacao de Energia Eletrica (Salvador and Bahia) and Eskom Holdings SOC Limited (Boshof, Soutpan, Witkop), accounted for 33% and 26% of our consolidated operating revenues, net, respectively.
Historically, with the exception of certain of our operations in China, the Company did not have any employees. The personnel that managed our operations (other than our Chairman and Interim Chief Executive Officer, Peter Blackmore, our Chief Operating Officer, Tom Studebaker, and our Interim Chief Accounting Officer, David Rawden) were employees of SunEdison and their services were provided to the Company under the Management Services Agreement with SunEdison or project level asset management and O&M services agreements. In a number of cases, the personnel that provided services to us also provided services to SunEdison and/or TerraForm Power during the same periods.
In light of the SunEdison Bankruptcy, we engaged in contingency planning to identify, and to be prepared to retain, key personnel to ensure continuity of the Company’s corporate and project level operations. As part of our efforts to create a stand-alone organization, we identified, and established a retention program for, key employees. On April 7, 2016 and April 21, 2016, the Conflicts Committee approved retention awards to encourage certain employees of SunEdison who carry out services for the Company, including certain officers of the Company, to remain employed by SunEdison and continue to provide services to the Company during and after the potential (as of April 7) and actual (as of April 21) SunEdison Bankruptcy.
In late 2016, the Company offered employment to such employees to ensure continuity of corporate and project level operations. As of January 1, 2017, substantially all employees at both the corporate and project levels who were previously employed by SunEdison were hired directly by the Company. As such, the Company no longer relies upon SunEdison for personnel to manage and operate our business or our power plants. While a number of our executive officers, including our Interim Chief Executive Officer, Peter Blackmore, our Executive Vice President and Chief Financial Officer, Rebecca Cranna, our Chief Operating Officer, Tom Studebaker, and our Interim Chief Accounting Officer, David Rawden, continue to serve in the same functions for TerraForm Power, most other officers and employees provide services exclusively to the Company.
As of May 31, 2017, the Company had 124 employees, the substantial majority of which were located outside the United States in the countries where our power plants are located.
