(a)
In 2017, 2016 and 2015, we recorded asset impairment charges of $58.1 million ($36.6 million net of tax), $8.0 million ($7.1 million net of tax) and $58.5 million ($44.6 million net of tax). The charges recorded in 2017 related to goodwill and intangible assets, including a $57.0 million goodwill impairment and a $1.1 million impairment of a customer relationship intangible asset. The goodwill impairment is associated with two reporting units within our Oil and Gas Infrastructure Services Division. The charges recorded in 2016 primarily related to a pending disposition of certain international renewable energy services operations, which was completed in 2017. The charges recorded in 2015 related to goodwill, intangible assets and property and equipment, including a $39.8 million goodwill impairment and a $12.1 million impairment to customer relationship, trade name and non-compete agreement intangible assets. For a discussion of these charges, refer to Results of Operations - Consolidated Results - Asset impairment charges included in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
(b)
The low effective tax rate in 2017 was primarily due to $70.1 million of tax benefits related to the enactment of the Tax Cuts and Jobs Act (Tax Act) on December 22, 2017. For more information and the status of our provisional analysis of the Tax Act, refer to Note 10 of the Notes to Consolidated Financial Statements in Item 8. Financial Statements and Supplementary Data. For more information on other items that impacted the effective tax rates in 2017, 2016 and 2015, refer to Results of Operations - Consolidated Results - Provision for income taxes included in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. The effective tax rates in 2014 and 2013 were impacted by $8.1 million and $9.9 million in tax benefits primarily due to decreases in reserves for uncertain tax positions resulting from the expiration of federal and state statute of limitations periods.
(c)
In 2014, selling, general and administrative expenses included a $102.5 million charge to provision for long-term contract receivable associated with an electric power infrastructure services project and a $38.8 million expense resulting from an arbitration decision associated with a contract dispute on a directional drilling project.
(d)
In 2013, we recorded a pre-tax gain of approximately $112.7 million from the sale of all of our equity ownership interest in Howard Midstream Energy Partners, LLC.
