Stock-Based Compensation [Text Block]

STOCK-BASED COMPENSATION

At June 25, 2016, the Company had one stock incentive plan, the Company's 1996 Stock Incentive Plan (the “1996 Plan”) and one employee stock purchase plan, the 2008 Employee Stock Purchase Plan (the “2008 ESPP”). The 1996 Plan was adopted by the Board of Directors to provide the grant of incentive stock options, nonstatutory stock options, restricted stock units (“RSUs”), and market stock units (“MSUs”) to employees, directors, and consultants.

Pursuant to the 1996 Plan, the exercise price for incentive stock options and non-statutory stock options is determined to be the fair market value of the underlying shares on the date of grant. Options typically vest ratably over a four-year period measured from the date of grant. Options generally expire no later than ten years after the date of grant, subject to earlier termination upon an optionee's cessation of employment or service.

RSUs granted to employees typically vest ratably over a four-year period and are converted into shares of the Company's common stock upon vesting, subject to the employee's continued service to the Company over that period.

MSUs granted to employees typically vest ratably over a two to four-year period and are converted into shares of the Company's common stock upon vesting, subject to the employee's continued service to the Company over that period. The number of shares that are released at the end of the performance period can range from zero to a maximum cap depending on the Company's performance. The performance metrics of this program are based on relative performance of the Company’s stock price as compared to the Semiconductor Exchange Traded Fund index, (the “SPDR S&P”).

Stock Options

The fair value of options granted to employees under the1996 Plan is estimated on the date of grant using the Black-Scholes option valuation model.

Expected volatilities are based on the historical volatilities from the Company’s traded common stock over a period equal to the expected term. The Company is utilizing the simplified method to estimate expected holding periods. The risk-free interest rate is based on the U.S. Treasury yield. The Company determines the dividend yield by dividing the annualized dividends per share by the prior quarter’s average stock price. The Company also estimates forfeitures at the time of grant and makes revisions to forfeitures on a quarterly basis.

The Company did not grant any stock options in fiscal year 2016. The fair value of options granted to employees in fiscal years 2015 and 2014 has been estimated using the following weighted-average assumptions:

	Stock Options For the Year Ended (1)
	June 27, 2015		June 28, 2014
Expected holding period (in years)	4.8		5.3
Risk-free interest rate	1.6	%	1.4	%
Expected stock price volatility	26.7	%	34.6	%
Dividend yield	3.2	%	3.2	%

(1) Table excludes impact from assumptions used in valuing the Volterra substitute options granted on October 1, 2013 based on an expected holding period of 3.8 years, risk-free interest rate of 1.0%, expected stock price volatility of 27.5% and dividend yield of 3.4%.

The weighted-average fair value of stock options granted were $5.56 and $7.36 per share for fiscal years 2015 and 2014, respectively.

The following table summarizes outstanding, exercisable and vested and expected to vest stock options as of June 25, 2016 and their activity during fiscal years 2016, 2015 and 2014:

	Options			Weighted Average Remaining Contractual Term (In Years)	Aggregate Intrinsic Value (1)
	Number of Shares		Weighted Average Exercise Price

Vested and expected to vest, June 25, 2016	5,794,417		$25.02	3.0	$	69,869,048

(1) Aggregate intrinsic value represents the difference between the exercise price and the closing price per share of the Company's common stock on June 24, 2016, the last business day preceding the fiscal year end, multiplied by the number of options outstanding, exercisable or vested and expected to vest as of June 25, 2016.

The following table summarizes information about stock options that were outstanding and exercisable at June 25, 2016:

	Outstanding Options			Options Exercisable
Range of Exercise Prices	Number Outstanding at June 25, 2016	Weighted Average Remaining Contractual Term (In years)	Weighted Average Exercise Price	Number Exercisable at June 25, 2016	Weighted Average Exercise Price
$12.00 - $20.00	1,068,741	1.2	$17.41	1,021,225	$17.32
$20.01 - $30.00	4,733,577	2.7	$26.63	2,186,711	$25.00
$30.01 - $40.00	132,761	4.0	$32.82	43,960	$32.29
	5,935,079			3,251,896

The total intrinsic value of options exercised during fiscal years 2016, 2015 and 2014 were $39.8 million, $45.6 million and $47.2 million, respectively. As of June 25, 2016, there was $7.1 million of total unrecognized compensation costs related to 2.7 million unvested stock options expected to be recognized over a weighted average period of approximately 1.2 years.

Restricted Stock Units and Other Awards

The fair value of Restricted Stock Units (“RSUs”) and other awards under the Company’s 1996 Plan is estimated using the value of the Company’s common stock on the date of grant, reduced by the present value of dividends expected to be paid on the Company’s common stock prior to vesting. The Company also estimates forfeitures at the time of grant and makes revisions to forfeitures on a quarterly basis.

The weighted-average fair value of RSUs and other awards granted was $29.75, $27.92 and $26.60 per share for fiscal years 2016, 2015 and 2014, respectively.

The following table summarizes outstanding and expected to vest RSUs and other awards as of June 25, 2016 and their activity during fiscal years 2016, 2015 and 2014:

	Number of Shares		Weighted Average Remaining Contractual Term (In years)	Aggregate Intrinsic Value (1)
Balance at June 29, 2013	7,965,532
Restricted stock units and other awards granted	3,916,111
Restricted stock units and other awards released	(2,904,787	)
Restricted stock units and other awards cancelled	(1,095,859	)

Expected to vest at June 25, 2016	5,588,721		2.5	$	207,229,781

(1) Aggregate intrinsic value for RSUs and other awards represents the closing price per share of the Company's common stock on June 24, 2016, the last business day preceding the fiscal year end, multiplied by the number of RSUs and other awards outstanding, or expected to vest as of June 25, 2016.

The Company withheld shares totaling $24.1 million in value as a result of employee withholding taxes based on the value of the RSUs on their vesting date for the fiscal year ended June 25, 2016. The total payments for the employees' tax obligations to the taxing authorities are reflected as financing activities within the Consolidated Statements of Cash Flows.

As of June 25, 2016, there was $131.3 million of unrecognized compensation cost related to 6.6 million unvested RSUs and other awards, which is expected to be recognized over a weighted average period of approximately 2.6 years.

Market Stock Units

The Company granted Market Stock Units (“MSUs”) to senior members of management in September 2014 and September 2015. The grant of MSUs was in lieu of granting stock options. MSUs are valued based on the relative performance of the Company’s stock price as compared to the Semiconductor Exchange Traded Fund index XSD, (the “SPDR S&P”). The fair value of MSUs is estimated using a Monte Carlo simulation model on the date of grant. The Company also estimates forfeitures at the time of grant and makes revisions to forfeitures on a quarterly basis. Compensation expense is recognized based on the initial valuation and is not subsequently adjusted as a result of the Company’s performance relative to that of the XSD index. Vesting for MSUs is contingent upon both service and market conditions, which is over a four-year period.

The following table summarizes the number of MSUs outstanding and expected to vest as of June 25, 2016 and their activity during fiscal years 2016, 2015 and 2014:

	Number of Shares		Weighted Average Remaining Contractual Term (In years)	Aggregate Intrinsic Value (1)
Balance at June 29, 2013 (2)	60,000
Market stock units granted	60,000
Market stock units released	—
Market stock units cancelled	—
Balance at June 28, 2014 (2)	120,000
Market stock units granted	423,044
Market stock units released	(42,476	)
Market stock units cancelled	(85,728	)
Balance at June 27, 2015	414,840
Market stock units granted	361,684
Market stock units released	—
Market stock units cancelled	(102,992	)
Balance at June 25, 2016	673,532		2.9	$	24,974,567
Expected to vest at June 25, 2016	547,546		2.9	$	20,303,011

(1) Aggregate intrinsic value for MSUs represents the closing price per share of the Company’s common stock on June 24, 2016, the last business day preceding the fiscal quarter-end, multiplied by the number of MSUs outstanding or expected to vest as of June 25, 2016.

(2) Reflects shares previously granted to the Company’s Chief Executive Officer only.

As of June 25, 2016, there was $11.9 million of unrecognized compensation cost related to 0.7 million unvested MSUs, which is expected to be recognized over a weighted average period of approximately 2.9 years.

At June 25, 2016, the Company had 28.0 million shares of its common stock available for issuance to employees and other option recipients under the 1996 Plan.

Employee Stock Purchase Plan

Employees are granted rights to acquire common stock under the Company’s 2008 Employee Stock Purchase Plan (the “ESPP”).

The Company issued 1.3 million shares of its common stock for total consideration of $34.0 million related to the ESPP plan during the fiscal year ended June 25, 2016. As of June 25, 2016, the Company had 6.1 million shares of its common stock reserved and available for future issuance under the ESPP.

The fair value of ESPP granted to employees in fiscal years 2016, 2015 and 2014 has been estimated at the date of grant using the Black-Scholes option valuation model using the following assumptions for the offering periods outstanding:

	ESPP For the Year Ended
	June 25, 2016	June 27, 2015		June 28, 2014
Expected holding period (in years)	0.5	0.5		0.5
Risk-free interest rate	0.1% - 0.5%	0.1	%	0.1% - 0.2%
Expected stock price volatility	21.8% - 33.1%	20.7% - 26.4%		20.7% - 25.5%
Dividend yield	3.3% - 3.6%	3.3% - 3.7%		3.1% - 3.7%

As of June 25, 2016, there was $5.5 million of unrecognized compensation expense related to the ESPP.

Other Modifications

In September 2006, the Company suspended the issuance of shares to employees upon exercise of stock options, vesting of restricted stock units or pursuant to planned purchases of stock under the Employee Stock Participation Plan until the Company became current with all required SEC filings and its registration statements on Form S-8 were declared effective (“Blackout Period”). The Company instituted multiple programs in an attempt to compensate employees during this period.

In September 2007, the Company decided to cash-settle all options expiring during the Blackout Period (“goodwill payment”) based on the price at which 10% of the daily close prices of the Company’s common stock fall above this price for trading days from August 7, 2006 (the date on which the Company initiated a trading blackout on officers and other individuals) through the expiration date of the option. The cash payment is subject to the option holder executing a release of all claims relating to the option. The supplemental goodwill payment modification changed the classification of the associated awards from equity to liability instruments. The modification resulted in a reclassification from additional paid-in capital to accrued salaries and related expenses.

In fiscal year 2015, $7.8 million was reclassified from accrued salaries to additional paid-in capital due to the lapse of the statute of limitations of certain option holders to raise claims relating to the expired options. No reclassification occurred in fiscal years 2016 or 2014.
