Acquisition and Related Costs
Acquisition and related costs, including amounts related to affiliates, were $55.8 million during the year ended December 31, 2015, compared to $15.2 million during the same period in 2014. These fees primarily consist of investment banking advisory fees and professional fees for legal and accounting services related to our consummated and pending acquisitions, including $5.8 million of shared costs allocated to us by SunEdison, which primarily related to the terminated Vivint acquisition. The increase relative to prior year was primarily due to the acquisitions of First Wind and Invenergy Wind and the terminated Vivint acquisition.
Loss on Prepaid Warranty - Affiliate
In conjunction with the First Wind Acquisition, SunEdison committed to reimburse the Company for capital expenditures and operations and maintenance labor fees in excess of budgeted amounts (not to exceed $53.9 million through 2019) for certain of its wind power plants. During the year ended December 31, 2015, the Company received contributions pursuant to this agreement of $4.3 million. The total amount related to capital expenditures of $50.0 million was initially recognized in renewable energy facilities as a prepaid warranty as the amount was part of the consideration paid on the acquisition date. As a result of the SunEdison Bankruptcy, the Company recorded a loss of $45.4 million during the year ended December 31, 2015 related to the write-off of the remaining balance of the prepaid warranty, which was net of depreciation expense of $1.9 million and capital expenditure reimbursements received of $2.7 million, and is reported as loss on prepaid warranty - affiliate in the consolidated statement of operations.
