All ordinary shares confer the same rights and obligations on the holders of each series of shares. Series BB shares have voting shares and other rights, such as the right to elect two members of the Board of Directors, and Series B shareholders are entitled to appoint the remaining members of the Board of Directors. Series BB may not represent more than 15% of the Company’s capital stock. Legal reserve The Company is legally required to allocate at least 5% of its unconsolidated annual net income to a legal reserve fund. This allocation must continue until the reserve is equal to 20% of the issued and outstanding capital stock of the Company. Mexican corporations may only pay dividends on retained earnings after the reserve fund for the year has been set up. Reserve for acquisition of shares The reserve for acquisition of shares represents the reservation authorized by the stockholders for the Company to purchase its own shares subject to certain criteria set forth in the bylaws and the Securities Market Law. At December 31, 2017 and 2018, the reserve for repurchase of shares totals Ps .7,052,635 and Ps9,862,262, respectively. Dividends At the April 26, 2017 General Ordinary Stockholders’ meeting, the Company’s stockholders agreed to pay net dividends of Ps1,848,000 (nominal), which don’t gave rise to income tax because the dividends were paid from the Net Tax Profit (CUFIN, by its initials in Spanish) At the April 26, 2018 General Ordinary Stockholders’ meeting, the Company’s stockholders agreed to pay net dividends of Ps2,034,000 (nominal), which don’t gave rise to IT because the dividends were paid from the Net Tax Profit Account (CUFIN, by its initials in Spanish). Dividends are tax free if paid from the CUFIN. Dividends paid in excess of the CUFIN balances are subject to tax equivalent to 42.86%. Tax due is payable by the Company and may be credited against income tax for the year or income tax for the two immediately following fiscal years. Dividends paid from previously taxed earnings are not subject to tax withholding or payment. At December 31, 2017 and 2018, the companies CUFIN lump sum is Ps8,951,912 and Ps11,382,509, respectively, whereas the combined contribution capital account amounts Ps39,689,426 and Ps 41,606,425 , respectively. In the event of a capital reduction, any excess of stockholders’ equity over paid-in capital contribution account balances is accorded the same tax treatment as dividends, in accordance with the procedures provided for in the Income Tax Law (ITL). Retained earnings Substantially, all consolidated Company earnings were generated by its subsidiaries. Retained earnings can be distributed to the Company’s shareholders to the extent that the subsidiaries have distributed earnings to the Company.
