(a)

As the company reported a net loss attributable to shareholders for the first nine months of 2019, basic and diluted net loss per share attributable to shareholders are the same and stock-based compensation awards for the issuance of 1,886 shares were excluded from the computation of net income per share on a diluted basis as their effect was anti-dilutive. Stock-based compensation awards for the issuance of 1,086 shares for the third quarter of 2019, and 582 and 540 shares for the third quarter and first nine months of 2018, respectively, were excluded from the computation of net income per share on a diluted basis as their effect was anti-dilutive.
