As described in detail in Note J, Equity Arrangements, the Company issued 7,500,000 Equity Units in May 2017 with a total notional value of $750.0 million. Each unit initially consists of 750,000 shares of convertible preferred stock and forward stock purchase contracts. On and after May 15, 2020, the convertible preferred stock may be converted into common stock at the option of the holder. At the election of the Company, upon conversion, the Company may deliver cash, common stock, or a combination thereof. The conversion rate was initially 6.1627 shares of common stock per one share of convertible preferred stock, which is equivalent to an initial conversion price of approximately $162.27 per share of common stock. As of September 29, 2018, due to the customary anti-dilution provisions, the conversion rate was 6.1744, equivalent to a conversion price of approximately $161.96 per share of common stock. The convertible preferred stock is excluded from the denominator of the diluted earnings per share calculation on the basis that the convertible preferred stock will be settled in cash except to the extent that the conversion value of the convertible preferred stock exceeds its liquidation preference. Therefore, before any redemption or conversion, the common shares that would be required to settle the applicable conversion value in excess of the liquidation preference, if the Company elects to settle such excess in common shares, are included in the denominator of diluted earnings per share in periods in which they are dilutive. The shares related to the convertible preferred stock have been anti-dilutive during most of 2018.
