Classes of stock
(l) Classes of stock(1) General rule. A corporation that has more than one class of stock does not qualify as a small business corporation. Except as provided in paragraph (l)(4) of this section (relating to instruments, obligations, or arrangements treated as a second class of stock), a corporation is treated as having only one class of stock if all outstanding shares of stock of the corporation confer identical rights to distribution and liquidation proceeds. Differences in voting rights among shares of stock of a corporation are disregarded in determining whether a corporation has more than one class of stock. Thus, if all shares of stock of an S corporation have identical rights to distribution and liquidation proceeds, the corporation may have voting and nonvoting common stock, a class of stock that may vote only on certain issues, irrevocable proxy agreements, or groups of shares that differ with respect to rights to elect members of the board of directors.
