Dividends attributable to our Series A 6% Convertible Perpetual Preferred Stock and Series B 6% Convertible Perpetual Preferred Stock (together, the “Series A and B Preferred Stock”) were excluded from the computation of diluted loss per share for the period from January 1, 2016 through September 12, 2016, as their assumed conversion would have been anti-dilutive.
2 The number of dilutive securities for the three and nine months ended September 30, 2017, which is attributable to RSUs and PRSUs, was determined under the “treasury stock” method.
The following table provides a reconciliation of the components used in the calculation of basic and diluted earnings (loss) per share for the periods presented:

The number of dilutive securities for the three months ended September 30, 2017, which is attributable to RSUs and PRSUs, was determined under the “treasury stock” method. For the three months ended September 30, 2017, approximately 0.1 million of potentially dilutive securities attributable to RSUs had the effect of being anti-dilutive and were excluded from the calculation of diluted loss per common share.
