Other In the three and nine months ended March 31, 2015 our results of operations were materially impacted by charges resulting from a change in estimate related to an acquired EPC joint venture project in the Electrical Infrastructure segment. The charges resulted in a reduction to operating income of $28.5 million and $54.7 million and an after-tax reduction of $9.7 million and $18.7 million to net income attributable to Matrix Service Company, respectively. The Company recorded additional charges on this project during the three and nine months ended March 31, 2016, which resulted in a reduction to operating income of $1.6 million and $7.1 million and an after-tax reduction to net income attributable to Matrix Service Company of $0.5 million and $2.5 million, respectively. The fiscal 2016 project charges are attributable to higher than expected project closeout costs. The Company reached substantial completion on the project in the fourth quarter of fiscal 2015.
