The 2019 Equity Units are potentially dilutive securities. The forward stock purchase contracts included within the 2019 Equity Units were excluded from the calculation of diluted EPS for the three and nine months ended September 30, 2019, as the dilutive stock price threshold was not met. The Series A Preferred Stock included within the 2019 Equity Units is excluded from the effect of dilutive securities within diluted EPS, but a fair value adjustment is reflected within net income attributable to Dominion Energy for the calculation of diluted EPS for the three and nine months ended September 30, 2019 based upon the expectation that the conversion will be settled in cash rather than through issuance of Dominion Energy common stock. The 2016 Equity Units were potentially dilutive securities, but were excluded from the calculation of diluted EPS for the three and nine months ended September 30, 2019 and 2018, as the dilutive stock price threshold was not met. The forward sales agreements, effective April 2018, were potentially dilutive securities but had no effect on the calculation of diluted EPS for the three and nine months ended September 30, 2018. The Dominion Energy Midstream convertible preferred units were potentially dilutive securities but had no effect on the calculation of diluted EPS for the three and nine months ended September 30, 2018. In calculating diluted EPS in connection with the Dominion Energy Midstream convertible preferred units, Dominion Energy applied the if-converted method.
