PHI Inc. in Lafayette, which provides helicopter transportation primarily to the oil and gas and air medical industries, reported net earnings for the three months ended June 30 totaled $13.4 million, down from $19.5 million for same period last year.

Excluding those non-recurring items, net income for the three months ended June 30, 2014, and June 30, 2013, was $13.9 million and $10.9 million, respectively, a $3 million increase.

Operating revenue for the three months ended June 30 was $212.1 million, compared to $195.5 million a year ago.
