| Loss Per Share Attributable to Navistar International Corporation                | Earnings (Loss) Per Share Attributable to Navistar International CorporationThe following table presents the information used in the calculation of our basic and diluted earnings (loss) per share all attributable to NIC in our Consolidated Statements of Operations: Three Months Ended January 31,(in millions, except per share data)20172016Numerator:   Net loss attributable to Navistar International Corporation common stockholders$(62) $(33)    Denominator:   Weighted average shares outstanding:   Basic81.8 81.7Effect of dilutive securities— —Diluted81.8 81.7    Net loss per share attributable to Navistar International Corporation:   Basic$(0.76) $(0.40)Diluted(0.76) (0.40)The conversion rate on our 4.5% Senior Subordinated Convertible Notes due 2018 (the "2018 Convertible Notes") is 17.1233 shares of common stock per $1,000 principal amount of 2018 Convertible Notes, equivalent to an initial conversion price of approximately $58.40 per share of common stock. The 2018 Convertible Notes have an anti-dilutive effect when calculating diluted earnings per share when our average stock price is less than $58.40. The conversion rate on our 4.75% Senior Subordinated Convertible Notes due 2019 (the “2019 Convertible Notes”) is 18.4946 shares of common stock per $1,000 principal amount of 2019 Convertible Notes, equivalent to an initial conversion price of approximately $54.07 per share of common stock. The 2019 Convertible Notes have an anti-dilutive effect when calculating diluted earnings per share when our average stock price is less than $54.07. The computation of diluted earnings per share also excludes outstanding options and other common stock equivalents in periods where inclusion of such potential common stock instruments would be anti-dilutive.For both the three months ended January 31, 2017 and 2016, no dilutive securities were included in the computation of diluted earnings per share because they would have been anti-dilutive due to the net loss attributable to NIC. Additionally, certain securities have been excluded from the computation of earnings per share, as our average stock price was less than their respective exercise prices. For the three months ended January 31, 2017 and 2016, the aggregate shares not included were 15.0 million for both periods.Pursuant to a Stock Purchase Agreement with Volkswagen Truck & Bus ("VW T&B"), on February 28, 2017 we issued and VW T&B purchased 16.2 million shares of our common stock for an aggregate purchase price of $256 million at $15.76 per share (an estimated 19.9% stake (16.6% on a pro forma basis) in the Company), excluding transaction costs.For both the three months ended January 31, 2017 and 2016, the aggregate shares not included in the computation of earnings per share were primarily comprised of 3.4 million shares related to the 2018 Convertible Notes and 7.6 million sharesrelated to the 2019 Convertible Notes. |
