Lafayette helicopter transportation company PHI Inc. swung from a $26.7 million loss in 2016 to net income of $7.5 million for 2017, attributed primarily to a federal tax overhaul in December that reduced corporate taxes.  

Without a $59 million tax benefit, PHI would have had a $51.4 million loss for 2017.

Annual revenue fell in 2017 to $579.5 million from $634.1 million in 2016. Revenue and income decreased in its oil and gas, air medical and technical services segments.
