(12) EQUITY AND STOCK-BASED COMPENSATION

Income Per Share

The following table sets forth the number of weighted-average shares outstanding used in the computation of basic and diluted income per share:

	Three months ended
	March 29,	March 30,
	2014	2013
Weighted-average number of common shares used in basic income per share	44.236	46.418
Dilutive securities — Employee stock options, restricted stock shares and restricted stock units	0.846	1.032
Weighted-average number of common shares and dilutive securities used in diluted income per share	45.082	47.450

There were no stock options outstanding during the three months ended March 29, 2014. All stock options outstanding were included in the computation of diluted income per share during the three months ended March 30, 2013.

All unvested restricted stock shares and restricted stock units were included in the computation of diluted income per share at March 29, 2014 because required market thresholds for vesting (as discussed in our 2013 Annual Report on Form 10-K) were met. The total number of unvested restricted stock shares and restricted stock units that were not included in the computation of diluted income per share because required market thresholds for vesting were not met was 0.225 at March 30, 2013.

Stock-based Compensation

Stock-based compensation awards may be granted to certain eligible employees or non-employee directors under the 2002 Stock Compensation Plan, or to non-employee directors under the 2006 Non-Employee Director’s Stock Incentive Plan. A detailed description of the awards granted under these plans is included in our 2013 Annual Report on Form 10-K.

Compensation expense within income from continuing operations related to restricted stock shares and restricted stock units totaled $24.7 and $20.3 for the three months ended March 29, 2014 and March 30, 2013, respectively, with a related tax benefit of $8.9 and $7.3 for the three months ended March 29, 2014 and March 30, 2013, respectively.

We use the Monte Carlo simulation model valuation technique to determine fair value of our restricted stock shares and restricted stock units that contain a “market condition.” The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award and calculates the fair value of each restricted stock share and restricted stock unit award. We used the following assumptions to determine the fair value of the awards granted on the dates indicated below:

							Correlation between total
	Annual expected						shareholder return for SPX
	stock price		Annual expected		Risk-free		and the applicable S&P
	volatility		dividend yield		interest rate		Composite Index
January 2, 2014:
SPX Corporation	33.7	%	1.02	%	0.76	%	0.7631
S&P Composite 1500 Industrials Index	19.9	%	n/a		0.76	%
April 1, 2013:
SPX Corporation	35.5	%	1.29	%	0.33	%	0.7668
S&P Composite 1500 Industrials Index	21.2	%	n/a		0.33	%
January 2, 2013:
SPX Corporation	36.3	%	1.42	%	0.37	%	0.7778
S&P Composite 1500 Industrials Index	22.4	%	n/a		0.37	%

Annual expected stock price volatility is based on the three-year historical volatility. The annual expected dividend yield is based on annual expected dividend payments and the stock price on the date of grant. The average risk-free interest rate is based on the one-year through three-year daily treasury yield curve rate as of the grant date.

Restricted Stock Share and Restricted Stock Unit Awards

The following table summarizes the restricted stock share and restricted stock unit activity from December 31, 2013 through March 29, 2014:

			Weighted-Average
	Unvested Restricted Stock Shares		Grant-Date Fair
	and Restricted Stock Units		Value Per Share
Outstanding at December 31, 2013	1.537		$	58.39
Granted	0.510		86.70
Vested	(0.537	)	58.57
Forfeited	(0.226	)	62.15
Outstanding at March 29, 2014	1.284		68.78

As of March 29, 2014, there was $38.7 of unrecognized compensation cost related to restricted stock share and restricted stock unit compensation arrangements. We expect this cost to be recognized over a weighted-average period of 2.3 years.

Accumulated Other Comprehensive Income

The changes in the components of accumulated other comprehensive income, net of tax, for the three months ended March 29, 2014 were as follows:

	Foreign Currency Translation Adjustment			Net Unrealized Losses on Qualifying Cash Flow Hedges (1)			Net Unrealized Losses on Available-for- Sale Securities			Pension and Postretirement Liability Adjustment and Other (2)			Total

Common Stock in Treasury

On December 18, 2013, we entered into a written trading plan under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, to facilitate the repurchase of up to $500.0 of shares of our common stock on or before December 31, 2014, in accordance with a share repurchase program authorized by our Board of Directors. During the first quarter of 2014, we repurchased 1.316 shares of our common stock for $134.3 under this trading plan. We repurchased 0.115 shares of our common stock for $11.2 under this trading plan during December 2013.

During the first quarter of 2013, we repurchased 1.514 shares of our common stock for $104.4, which completed the repurchases under a trading plan that we entered into during 2012. In addition, we repurchased 0.333 shares of our common stock on the open market for $27.0 during the first quarter of 2013.

During the three months ended March 29, 2014, “Common stock in treasury” was decreased by the settlement of restricted stock units issued from treasury stock of $12.0 and increased by $7.9 for common stock that was surrendered by recipients of restricted stock as a means of funding the related minimum income tax withholding requirements.

During the three months ended March 30, 2013, “Common stock in treasury” was decreased by the settlement of restricted stock units issued from treasury stock of $13.6 and increased by $9.0 for common stock that was surrendered by recipients of restricted stock as a means of funding the related minimum income tax withholding requirements.

We paid first quarter dividends on April 2, 2014 and April 2, 2013.
