a) (Loss) Earnings per share

Basic (loss) earnings per share (“LPS or EPS”) amounts are calculated by dividing the net (loss) income for the year attributable to ordinary equity holders of the parent by the weighted average number of ordinary shares outstanding during the year.

Diluted LPS or EPS amounts are calculated by dividing the (loss) profit attributable to ordinary equity holders of the parent (after adjusting for interest on the convertible preference shares, if any), by the weighted average number of ordinary shares outstanding during the year plus the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares (to the extent that their effect is dilutive).

The following table shows the calculations of the basic and diluted (loss) earnings per share for the years ended December 31, 2018, 2017 and 2016.

In accordance with the Mexican Corporations Act, the Company is required to allocate at least 5% of the net income of each year to increase the legal reserve. This practice must be continued until the legal reserve reaches 20% of capital stock. As of December 31, 2018 and 2017, the Company’s legal reserve was Ps.291,178 or 9.8% our capital stock. As of December 31, 2016 the legal reserve was Ps.38,250.

c) Any distribution of earnings in excess of the net tax profit account (Cuenta de utilidad fiscal neta or “CUFIN”) balance will be subject to corporate income tax, payable by the Company, at the enacted income tax rate at that time. A 10% withholding tax is imposed on dividends distributions to individuals and foreign shareholders from earnings generated starting January 1, 2014.

d) Shareholders may contribute certain amounts for future increases in capital stock, either in the fixed or variable capital. Said contributions will be kept in a special account until the shareholders meeting authorizes an increase in the capital stock of the Company, at which time each shareholder will have a preferential right to subscribe and pay the increase with the contributions previously made. As it is not strictly regulated in Mexican law, the shareholders meeting may agree to return the contributions to the shareholders or even set a term in which the increase in the capital stock has to be authorized.
