| Stock Options and Other Share-Based Compensation                          | Stock Options and Other Share-Based CompensationDuring the three quarters ended April 1, 2016, we had options or other share-based compensation outstanding under two shareholder-approved stock incentive plans (“SIPs”), the Harris Corporation 2005 Equity Incentive Plan (As Amended and Restated Effective August 27, 2010) and the Harris Corporation 2015 Equity Incentive Plan. We have granted the following types of share-based awards under these SIPs: stock options, restricted stock awards, restricted stock unit awards, performance share awards, performance share unit awards and awards of immediately vested shares of our common stock. We believe that such awards more closely align the interests of participants with those of shareholders. Certain share-based awards provide for accelerated vesting if there is a change in control (as defined under our SIPs). The compensation cost related to our share-based awards that was charged against income was $10 million and $29 million for the quarter and three quarters ended April 1, 2016, respectively. The compensation cost related to our share-based awards that was charged against income was $9 million and $26 million for the quarter and three quarters ended April 3, 2015, respectively.Grants to participants under our SIPs during the third quarter ended April 1, 2016 consisted of 14,000 restricted stock awards. Grants to participants under our SIPs during the three quarters ended April 1, 2016 consisted of 1,658,000 stock options, 114,270 restricted stock awards and 292,665 performance share unit awards. The fair value as of the grant date of each stock option award was determined using the Black-Scholes-Merton option-pricing model, which used the following assumptions: expected dividend yield of 2.50 percent; expected volatility of 23.01 percent; risk-free interest rates averaging 1.52 percent; and expected term in years of 5.05. The fair value as of the grant date of each restricted stock award was based on the closing price of our common stock on the grant date. The fair value as of the grant date of each performance share unit award was determined based on the fair value from a multifactor Monte Carlo valuation model that simulates our stock price and total shareholder return (“TSR”) relative to other companies in our TSR peer group, less a discount to reflect the delay in payments of cash dividend-equivalents that are made only upon vesting. |
