The aggregate intrinsic value of outstanding stock options represents amounts that would have been received by the optionees had all in- the-money options been exercised on that date. Specifically, it is the amount by which the market value of Itron’s stock exceeded the exercise price of the outstanding in-the-money options before applicable income taxes, based on our closing stock price on the last business day of the period. The aggregate intrinsic value of stock options exercised during the period is calculated based on our stock price at the date of exercise.

Restricted Stock Units, Valuation Assumptions

The weighted-average assumptions used to estimate the fair value of performance-based restricted stock units awarded and the resulting weighted average fair-value are as follows:



	Three Months Ended March 31,
	2014			2013
Dividend yield	0.0		%	0.0		%
Expected volatility	30.9		%	31.9		%
Risk-free interest rate	0.2		%	0.3		%

Restricted Stock Units Award Activity [Table Text Block]

The following table summarizes restricted stock unit activity for the three months ended March 31:



	Number of Restricted Stock Units		Weighted Average Grant Date Fair Value		Aggregate Intrinsic Value⁽¹⁾

Vested but not released, March 31, 2014	8				$	300

Expected to vest, March 31, 2014	605				$	21,503


⁽¹⁾	The aggregate intrinsic value is the market value of the stock, before applicable income taxes, based on the closing price on the stock release dates or at the end of the period for restricted stock units expected to vest.


⁽²⁾	Restricted stock units granted in 2013 and 2014 do not include awards under the Performance Award Agreement for the respective years, as these awards are not granted until attainment of annual performance goals has been determined at the conclusion of the performance period, which had not occurred as of March 31, 2013 and 2014, respectively.

Nonrestricted Stock Awards Activity [Table Text Block]

The following table summarizes unrestricted stock award activity for the three months ended March 31:



	Three Months Ended March 31,

Shares of unrestricted stock granted	6		4

Weighted average grant date fair value per share	$	40.63	$	45.43

Employee Stock Purchase Plan (ESPP) Activity [Table Text Block]

The following table summarizes ESPP activity for the three months ended March 31:



	Three Months Ended March 31,
	2014		2013
	(in thousands, except per share data)
Shares of stock sold to employees⁽¹⁾	14		20

Weighted average fair value per ESPP award⁽²⁾	$	—	$	6.96


⁽¹⁾	Stock sold to employees during each fiscal quarter under the ESPP is associated with the offering period ending on the last day of the previous fiscal quarter.


⁽²⁾	Effective October 1, 2013, the ESPP is no longer compensatory, and therefore the weighted average fair value per award is not applicable for the three months ended March 31, 2014.

- Definition

Tabular disclosure of components of a stock option or other award plan under which equity-based compensation is awarded to employees, typically comprised of the amount of unearned compensation (deferred compensation cost), compensation expense, and changes in the quantity and fair value of the shares (or other type of equity) granted, exercised, forfeited, and issued and outstanding pertaining to that plan. Disclosure may also include nature and general terms of such arrangements that existed during the period and potential effects of those arrangements on shareholders, effect of compensation cost arising from equity-based payment arrangements on the income statement, method of estimating the fair value of the goods or services received, or the fair value of the equity instruments granted, during the period, cash flow effects resulting from equity-based payment arrangements and, for registrants that accelerate vesting of out of the money share options, reasons for the decision to accelerate.
