[1] For the three and nine-months ended September 30, 2019, there were 2,704 and 5,200 shares, respectively, excluded from the diluted EPS calculation because the impact of their assumed vesting would be anti-dilutive due to a net loss in those periods.

[2] As described in Note 2 to these Consolidated Financial Statements, we have restated the Consolidated Financial Statements.
