During the three months ended December 31, 2016, the Company recognized an approximate $0.8 million charge to correct for a $0.3 million understatement of expense related primarily to the nine months ended September 30, 2016 in our International Telecom segment and a $0.5 million reduction to revenue primarily related to the nine months ended September 30, 2016 in our Renewable Energy segment.

The Company determined that the impact of the correction of these errors was not material to the current or any prior period financial statements.
