| STOCK OPTIONS AND OTHER SHARE-BASED COMPENSATION                              | STOCK OPTIONS AND OTHER SHARE-BASED COMPENSATIONAs of July 1, 2016, we had options or other share-based compensation outstanding under two shareholder-approved employee 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”) (prior to July 3, 2015, we had an additional shareholder approved SIP under which options or other share-based compensations was outstanding). We have granted the following types of share-based awards under our 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).Summary of Share-Based Compensation ExpenseThe following table summarizes the amounts and classification of share-based compensation expense: 2016 2015 2014       (In millions)Total expense$39 $37 $35Included in:     Cost of product sales and services$4 $4 $4Engineering, selling and administrative expenses35 33 31Income from continuing operations39 37 35Tax effect on share-based compensation expense(15) (11) (11)Total share-based compensation expense after-tax$24 $26 $24Compensation cost related to share-based compensation arrangements that was capitalized as part of inventory or fixed assets in fiscal 2016, 2015 and 2014 was not material.Shares of common stock remaining available for future issuance under our 2015 EIP totaled 31,817,456 as of July 1, 2016. In fiscal 2016, we issued an aggregate of 967,659 shares of common stock under the terms of our SIPs, which is net of shares withheld for tax purposes.Stock OptionsThe following information relates to stock options, including performance stock options, that have been granted under shareholder-approved SIPs. Option exercise prices are equal to or greater than the fair market value of our common stock on the date the options are granted, using the closing stock price of our common stock. Options may be exercised for a period set at the time of grant, which generally ranges from seven to ten years after the date of grant, and options, other than performance stock options, generally become exercisable in installments, which are typically 33.3 percent one year from the grant date, 33.3 percent two years from the grant date and 33.3 percent three years from the grant date. In certain instances, vesting and exercisability are also subject to performance criteria.The fair value as of the grant date of each option award was determined using the Black-Scholes-Merton option-pricing model which uses assumptions noted in the following table. Expected volatility over the expected term of the options is based on implied volatility from traded options on our common stock and the historical volatility of our stock price. The expected term of the options is based on historical observations of our common stock, considering average years to exercise for all options exercised and average years to cancellation for all options cancelled, as well as average years remaining for vested outstanding options, which is calculated based on the weighted-average of these three inputs. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.A summary of the significant assumptions used in determining the fair value of stock option grants under our SIPs is as follows: 2016 2015 2014      Expected dividends2.5% 2.7% 2.8%Expected volatility23.0% 24.3% 30.7%Risk-free interest rates1.5% 1.7% 1.7%Expected term (years)5.05 5.02 5.10A summary of stock option activity under our SIPs as of July 1, 2016 and changes during fiscal 2016 is as follows: Shares WeightedAverageExercisePricePer Share WeightedAverageRemainingContractualTerm AggregateIntrinsic Value     (In years) (In millions)Stock options outstanding at July 3, 20154,228,123 $54.99    Stock options forfeited or expired(287,507) $72.91    Stock options granted1,658,000 $77.57    Stock options exercised(662,771) $49.38    Stock options outstanding at July 1, 20164,935,845 $62.28 7.50 $100.25Stock options exercisable at July 1, 20162,252,136 $48.19 6.09 $77.47The weighted-average grant-date fair value was $12.68 per share, $12.51 per share and $12.40 per share for options granted during fiscal 2016, 2015 and 2014, respectively. The total intrinsic value of options exercised during fiscal 2016, 2015 and 2014 was $20 million, $20 million and $51 million, respectively, at the time of exercise.A summary of the status of our nonvested stock options at July 1, 2016 and changes during fiscal 2016 is as follows: Shares Weighted-AverageGrant-DateFair ValuePer ShareNonvested stock options at July 3, 20152,318,908 $12.16Stock options granted1,658,000 $12.68Stock options vested(1,293,199) $11.83Nonvested stock options at July 1, 20162,683,709 $12.64As of July 1, 2016, there was $34 million of total unrecognized compensation cost related to nonvested stock options granted under our SIPs. This cost is expected to be recognized over a weighted-average period of 1.69 years. The total fair value of stock options that vested during fiscal 2016, 2015 and 2014 was approximately $15 million, $16 million and $16 million, respectively.Restricted Stock and Restricted Stock Unit AwardsThe following information relates to awards of restricted stock and restricted stock units that have been granted to employees under our SIPs. These awards are not transferable until vested and the restrictions generally lapse upon the achievement of continued employment over a specified time period.The fair value as of the grant date of these awards was based on the closing price of our common stock on the grant date and is amortized to compensation expense over the vesting period. At July 1, 2016, there were 198,748 shares of restricted stock and 213,127 restricted stock units outstanding, substantially all of which were payable in shares.A summary of the status of these awards at July 1, 2016 and changes during fiscal 2016 is as follows: Shares Weighted-AverageGrantPricePer ShareRestricted stock and restricted stock units outstanding at July 3, 2015462,448 $63.48Restricted stock and restricted stock units granted125,900 $81.53Restricted stock and restricted stock units vested(127,443) $51.23Restricted stock and restricted stock units forfeited(49,030) $77.95Restricted stock and restricted stock units outstanding at July 1, 2016411,875 $71.07As of July 1, 2016, there was $12 million of total unrecognized compensation cost related to these awards under our SIPs. This cost is expected to be recognized over a weighted-average period of 1.21 years. The weighted-average grant date price per share or per unit of these awards granted during fiscal 2016, 2015 and 2014 was $81.53, $78.05 and $61.39, respectively. The total fair value of these awards that vested during fiscal 2016, 2015 and 2014 was approximately $7 million, $14 million and $12 million, respectively.Performance Share and Performance Share Unit AwardsThe following information relates to awards of performance shares and performance share units that have been granted to employees under our SIPs. Generally, these awards are subject to performance criteria, such as meeting predetermined operating income or earnings per share and return on invested capital targets (and market conditions, such as total shareholder return) for a 3-year performance period. These awards also generally vest at the expiration of the same 3-year period. The final determination of the number of shares to be issued in respect of an award is made by our Board of Directors or a committee of our Board of Directors.The fair value as of the grant date of these awards was determined based on a 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. The fair value of these awards is amortized to compensation expense over the vesting period if achievement of the performance measures is considered probable. At July 1, 2016, there were no performance shares outstanding, and there were 681,731 performance share units outstanding, all of which were payable in shares.A summary of the status of these awards at July 1, 2016 and changes during fiscal 2016 is as follows: Shares Weighted-AverageGrantPricePer SharePerformance share units outstanding at July 3, 2015763,356 $56.33Performance share units granted356,666 $73.32Performance share units vested(376,103) $47.51Performance share units forfeited(62,188) $68.92Performance share units outstanding at July 1, 2016681,731 $68.94As of July 1, 2016, there was $19 million of total unrecognized compensation cost related to these awards under our SIPs. This cost is expected to be recognized over a weighted-average period of 1.20 years. The weighted-average grant date price per share or per unit of these awards granted during fiscal 2016, 2015 and 2014 was $73.32, $64.23 and $59.17, respectively. The total fair value of these awards that vested during fiscal 2016, 2015 and 2014 was approximately $18 million, $7 million and $4 million, respectively. |
