The Company had combined undistributed and distributed earnings to participating securities totaling $21 in the first quarter of 2018 and $2 in the first quarter of 2017.

The Company had options outstanding for approximately 17 and 9 shares during the first quarter of 2018 and 2017, respectively that were excluded from the computations of net earnings per diluted common share because their inclusion would have had an anti-dilutive effect on net earnings per share.
