The founders of a startup award themselves 1,000,000 shares of Series A common stock. The company then undergoes two rounds of external funding. The table below shows the number of shares issued and the price per share during each round. The table also shows the liquidation preference for the shareholders in each round. Series B and Series C both have seniority over common shareholders, but neither has seniority over the other (ie. Series C is pari passu). Series B and Series C shareholders have the right to convert their shares to common shares at any point. Round Price Per Share Liquidation Pref.
