We have deferred compensation plans for directors and certain of our employees. Some amounts owed to participants are denominated in common stock units. Each unit represents one share of common stock. The number of shares used to calculate basic earnings per share includes the weighted-average common stock units credited to employees and directors under the deferred compensation plans. Additionally, nonvested units containing only a service requirement are also included in the computation of basic weighted-average shares when the requisite service period has been completed. Accordingly, included in basic shares are 0.3 million in the three months ended March 31, 2020, and 0.3 million in the three months ended March 31, 2019.
