(15) Shareholders' Equity and Stock-Based Compensation

Income Per Share

The following table sets forth the computations of the components used for the calculation of basic and diluted income per share:

	Year ended December 31,
	2014			2013		2012
Numerator:
Income (loss) from continuing operations	$	380.1		$	211.3	$	(165.2	)
Less: Net income (loss) attributable to noncontrolling interests		(9.5	)		2.2		3.0

Income (loss) from continuing operations attributable to SPX Corporation common shareholders for calculating basic and diluted income per share	$	389.6		$	209.1	$	(168.2	)


Income from discontinued operations	$	8.3		$	1.3	$	348.4
Less: Net income (loss) attributable to noncontrolling interest		—			0.2		(0.2	)

Income from discontinued operations attributable to SPX Corporation common shareholders for calculating basic and diluted income per share	$	8.3		$	1.1	$	348.6


Denominator:
Weighted-average number of common shares used in basic income per share		42.400			45.384		50.031
Dilutive securities — Employee stock options, restricted stock shares and restricted stock units		0.631			0.622		—

Weighted-average number of common shares and dilutive securities used in diluted income per share		43.031			46.006		50.031

There were no stock options outstanding during the year ended December 31, 2014, and all stock options outstanding were included in the computation of diluted income per share for the year ended December 31, 2013. The total number of stock options not included in the computation of diluted income per share because their exercise price was greater than the average market price of common shares was 0.003 for the year ended December 31, 2012. 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 (as discussed below) were not met was 0.226, 0.647 and 1.031 at December 31, 2014, 2013 and 2012, respectively.

Common Stock and Treasury Stock

At December 31, 2014, we had 200.0 authorized shares of common stock (par value $10.00). Common shares issued, treasury shares and shares outstanding are summarized in the table below.

	Common Stock Issued		Treasury Stock			Shares Outstanding

Stock-Based Compensation

Under the 2002 Stock Compensation Plan, as amended in 2006, 2011 and 2012, up to 2.305 shares of our common stock were available for grant at December 31, 2014. The 2002 Stock Compensation Plan permits the issuance of new shares or shares from treasury upon the exercise of options, vesting of restricted stock units, or granting of restricted stock shares. Each share of restricted stock and restricted stock unit granted reduces availability by two shares.

During the years ended December 31, 2014, 2013 and 2012, we classified excess tax benefits from stock-based compensation of $9.7, $6.3 and $3.8, respectively, as financing cash flows and included such amounts in "Minimum withholdings paid on behalf of employees for net share settlements, net of proceeds from the exercise of employee stock options and other" within our consolidated statements of cash flows.

Restricted stock shares or restricted stock units may be granted to certain eligible employees or non-employee directors in accordance with applicable equity compensation plan documents and agreements. Subject to participants' continued employment and other plan terms and conditions, the restrictions lapse and awards generally vest over a period of time, generally one or three years. In some instances, such as death, disability, or retirement, stock may vest concurrently with or following an employee's termination. A substantial portion of the restricted stock shares and restricted stock unit awards vest based on performance thresholds, while the remaining portion vest based on the passage of time since grant date.

Eligible employees received target performance awards in 2014 and 2013 in which the employee can earn between 25% and 125% of the target performance award in the event the award meets the required vesting criteria. Vesting for the 2014 and 2013 target performance awards is based on SPX shareholder return versus the S&P Composite 1500 Industrials Index over three-year periods ending December 31, 2016 and December 31, 2015, respectively.

Each eligible non-officer employee also received awards in 2014, 2013 and 2012 that vest ratably over three years, subject only to the passage of time. Officers received awards in 2014 and 2013 that vest ratably over three years, subject to an internal performance metric.

Vesting for the 2012 target performance awards was based on the SPX shareholder return versus the S&P 500 Index. On each vesting date, we compared the SPX shareholder return to the performance of the S&P 500 Index for the prior year and for the cumulative period since the date of the grant. If SPX outperformed the S&P 500 Index for the prior year, the one-third portion of the grant associated with that year vested. If SPX outperformed the S&P 500 Index for the cumulative period, any unvested portion of the grant that was subject to vesting on or prior to the vesting date vested.

We grant restricted stock shares to non-employee directors under the 2006 Non-Employee Directors' Stock Incentive Plan (the "Directors' Plan") and the 2002 Stock Compensation Plan. Under the Directors' Plan, up to 0.022 shares of our common stock were available for grant at December 31, 2014. The 2014 and 2013 restricted stock grants to non-employee directors generally vest over a one-year vesting period.

The 2012 restricted stock grants to non-employee directors had a three-year vesting period based on SPX shareholder return versus the S&P 500 Index, and were subject to the same company performance thresholds as the employee 2012 awards described above.

Restricted stock shares and restricted stock units that do not vest within the applicable vesting period are forfeited.

Stock options may be granted to key employees in the form of incentive stock options or nonqualified stock options. The option price per share may be no less than the fair market value of our common stock at the close of business the day prior to the date of grant. Upon exercise, the employee has the option to surrender previously owned shares at current value in payment of the exercise price and/or for withholding tax obligations. As of December 31, 2014, we had not granted options to any of our employees since 2004, and there were no options outstanding as of December 31, 2014 and 2013.

The recognition of compensation expense for share-based awards, including stock options, is based on their grant date fair values. The fair value of each award is amortized over the lesser of the award's requisite or derived service period, which is generally up to three years. There was no stock option expense for the years ended December 31, 2014, 2013 and 2012. Compensation expense within income from continuing operations related to restricted stock shares and restricted stock units totaled $38.4, $32.9 and $38.9 for the years ended December 31, 2014, 2013 and 2012, respectively, with the related tax benefit being $14.1, $12.1 and $14.8 for the years ended December 31, 2014, 2013 and 2012, respectively.

We use the Monte Carlo simulation model valuation technique to determine fair value of our restricted stock shares and restricted stock units as they 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 in determining the fair value of the awards granted on the dates indicated below:

	Annual Expected Stock Price Volatility			Annual Expected Dividend Yield			Risk-free Interest Rate			Correlation Between Total Shareholder Return for SPX and the Applicable S&P 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	%
January 3, 2012:
SPX Corporation		44.3	%		1.60	%		0.44	%		0.7365
S&P 500 Index		23.1	%		n/a			0.44	%

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, 2011 through December 31, 2014:
