SunEdison Bankruptcy and Settlement with SunEdison
As discussed in Note 1. Nature of Operations and Basis of Presentation, TerraForm Power entered into the Settlement Agreement with SunEdison on March 6, 2017, which was approved by the Bankruptcy Court. The settlements, mutual intercompany releases and certain other terms and conditions became effective upon the consummation of the Merger with affiliates of Brookfield on October 16, 2017. The effectiveness of these Settlement Agreement provisions has resolved claims between TerraForm Power and SunEdison, including, among other things, claims of SunEdison against the Company for alleged fraudulent and preferential transfers and claims of the Company against SunEdison, including those outlined in the initial proof of claim filed by the Company in the SunEdison Bankruptcy on September 25, 2016 and on October 7, 2016. Under the Settlement Agreement, all such claims have been mutually released. Moreover, with certain limited exceptions, any agreements between SunEdison Debtors and SunEdison parties to the Settlement Agreement on the one hand and the Company on the other hand have been deemed rejected without further liability, claims or damages on the part of the Company. These exceptions included directors' and officers' liability insurance allocation agreements and certain corporate and project-level transition services agreements.
Historical Management Services Agreement with SunEdison
Historically, general and administrative expenses - affiliate primarily represented costs incurred by SunEdison for services provided to the Company pursuant to the management services agreement (the "SunEdison MSA"). Pursuant to the SunEdison MSA, SunEdison agreed to provide or arrange for other service providers to provide management and administrative services to the Company. As consideration for the services provided, the Company agreed to pay SunEdison a base management fee equal to 2.5% of the Company's cash available for distribution in 2015, 2016 and 2017 but not to exceed $4.0 million in 2015, $7.0 million in 2016 or $9.0 million in 2017. Subsequent to the SunEdison Bankruptcy, SunEdison continued to provide some of these services, including services related to information technology, human resources, tax, treasury, finance and controllership, but stopped providing or reimbursing the Company for other services.
The Company entered into a corporate-level transition services agreement with SunEdison on September 7, 2017 that covered the services that SunEdison continued to provide under the SunEdison MSA and retroactively applied to transition services provided since February 1, 2017. The Company paid SunEdison certain monthly fees in exchange for these services at rates consistent with past practice. Amounts incurred by the Company under this transition services agreement with SunEdison and by SunEdison under the SunEdison MSA totaled $4.5 million, $12.0 million and $54.3 million for the years ended December 31, 2017, 2016 and 2015, respectively, and are reported within general and administrative expenses - affiliate in the consolidated statements of operations. As discussed above, the SunEdison MSA was rejected without further liability, claims or damages on the part of the Company pursuant to the Settlement Agreement upon the closing of the Merger. The corporate-level transition services agreement was extended through the end of the fourth quarter of 2017 with respect to certain information technology services. Amounts incurred for these services subsequent to the Merger closing date on October 16, 2017 are included within general and administrative expenses in the consolidated statement of operations since SunEdison was no longer an affiliate of the Company.
Historical O&M and Asset Management Services with SunEdison
O&M services, as well as asset management services, were historically provided to the Company substantially by SunEdison pursuant to contractual agreements. The Company has completed its transition away from SunEdison for these services, with the exception of services provided to its 101.6 MW renewable energy facility in Chile. In the first half of 2017, the Company entered into certain transition services agreements with SunEdison to facilitate this transition. These transition services agreements allowed the Company, among other things, to hire employees of SunEdison that were performing these project-level services for the Company and to terminate project-level asset management and O&M services on 10 days advance notice. Total costs incurred for O&M and asset management services from SunEdison were $17.6 million, $26.7 million and
