Ulrich Foundations issued 3,000 shares of $40 par value convertible preferred stock, sold initially at $60. Their common stock has an initial selling price of $10, par value of $5, and current market price of $20. How many common shares should they offer in their conversion option for each preferred share if they want to offer enough common stock shares per preferred stock share so they do not have to record anything in the Paid-in Capital in Excess of ParCommon Stock account?
