In the years ended December 31, 2019, 2018 and 2017, we excluded from the calculation 12.0 million, 10.6 million and 4.7 million share-based awards, respectively, since the effect would have been anti-dilutive. In the years ended December 31, 2019 and 2018, we excluded from the calculation 84.0 million and 77.2 million shares, respectively, issuable upon conversion of the Exchangeable Bonds since the effect would have been anti-dilutive.
