During the three months ended December 31, 2015, the Company recognized an approximate $0.7 million benefit to correct for tax basis differences and expense recognition related to prior periods. Of these errors, $0.7 million primarily related to the three months ended September 30, 2015.

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.
