| Stock Options and Other Share-Based Compensation                              | Stock Options and Other Share-Based CompensationDuring the two quarters ended December 30, 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 (the “2015 EIP”). Grants of share-based awards after October 23, 2015 were made under our 2015 EIP.  We believe that share-based 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 $11 million and $22 million for the quarter and two quarters endedDecember 30, 2016, respectively. The compensation cost related to our share-based awards that was charged against income was $9 million and $19 million for the quarter and two quarters endedJanuary 1, 2016, respectively. Grants to participants under our 2015 EIP during the second quarter ended December 30, 2016 consisted of 19,750 stock options, 13,665 restricted share awards and restricted share unit awards, and 12,820 performance unit awards. Grants to participants under our 2015 EIP during the two quarters ended December 30, 2016 consisted of 1,230,480 stock options, 81,860 restricted share awards and restricted share unit awards, and 261,275 performance 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 2.36 percent; expected volatility of 21.78 percent; risk-free interest rates averaging 1.23 percent; and expected term in years of 5.03. The fair value as of the grant date of each restricted share 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 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 relative to companies in the Standard & Poor’s 500, less a discount to reflect the delay in payments of cash dividend-equivalents that are made only upon vesting. |
