[1] As a result of the net loss in the three and six months ended June 30, 2018, and the six months ended June 30, 2017, the effect of potentially dilutive securities would have been anti-dilutive and have been omitted from the calculation of diluted earnings per share.

[2] Revised for the impact of the adoption of a new pension accounting pronouncement (see Note 9 – “Pension and Post-Retirement Benefit Plans”) for further detail.
