Earnings Per Share (“EPS”)

Basic EPS is computed by dividing net income attributable to Kraton by the weighted-average number of shares outstanding during the period. Diluted EPS is computed by dividing net income attributable to Kraton by the diluted weighted-average number of shares outstanding during the period and, accordingly, reflects the potential dilution that could occur if securities or other agreements to issue common stock, such as stock options, were exercised, settled or converted into common stock and were dilutive. The diluted weighted-average number of shares used in our diluted EPS calculation is determined using the treasury stock method.

The calculations of basic and diluted EPS are as follows:

Share Repurchase Program. In February 2019, we announced a repurchase program for up to $50.0 million of the Company's common stock by March 2021. Repurchases may be made at management's discretion from time to time through privately-negotiated transactions, in the open market, or through broker-negotiated purchases in compliance with applicable securities law, including through a 10b5-1 Plan. The repurchase program may be suspended for periods or discontinued at any time, and the amount and timing of the repurchases are subject to a number of factors, including Kraton's stock price. During the three months ended March 31, 2019, we did not repurchase any shares of our common stock. We are not obligated to acquire any specific number of shares of our common stock.
