Note 10. Share-Based Compensation Plans

We grant share-based compensation to our employees and directors. At December 31, 2014, an aggregate of 2,565,196 shares were authorized for future grant under our various share-based compensation plans, including stock options, restricted stock units, and restricted stock awards. Awards that expire or are canceled without delivery of shares generally become available for issuance under the plans. Upon exercises of stock options, vesting of restricted stock units, and vesting of restricted shares under all of our stock plans, we issue new shares of Reliance common stock.

Restricted Shares

In 2014, 2013 and 2012, we granted 349,380, 327,780 and 391,050, respectively, restricted stock units ("RSUs") to key employees pursuant to the Amended and Restated Stock Option and Restricted Stock Plan. Each RSU consists of the right to receive one share of our common stock and dividend equivalent rights, subject to forfeiture, equal to the accrued cash or stock dividends where the record date for such dividends is after the grant date but before the shares vest. Additionally, each 2014, 2013 and 2012 RSU granted has a service condition and cliff vests at December 31, 2017, December 31, 2016 and December 31, 2015, respectively, if the recipient is an employee on those dates. In addition to the service criteria, 136,162, 136,225, and 138,700 of the RSUs granted in 2014, 2013 and 2012, respectively, also have performance goals and vest only upon the satisfaction of the service and performance criteria. The fair value of the 2014, 2013 and 2012 RSUs granted was $71.15 per share, $65.75 per share and $57.42 per share, respectively, determined based on the closing price of our common stock on the day of the grant.

In 2011 and 2010, we granted 86,000 and 61,000 shares, respectively, of restricted stock to certain officers of the Company. The awards include dividend rights and vest over five years. The fair value of the 2011 and 2010 restricted stock grants was $37.29 per share and $41.24 per share, respectively, determined based on the closing price of our common stock on the grant date. As of December 31, 2014, 46,600 of these shares remain unvested and outstanding.

In 2014, 2013 and 2012, 11,830, 12,418, and 16,842 shares of restricted stock, respectively, were granted to the non-employee members of the Board of Directors pursuant to the Directors Equity Plan. The fair value of the restricted stock granted in 2014, 2013, and 2012, was $70.99 per share, $67.63 per share, and $49.87 per share, respectively, the closing price of our common stock on the grant date. The awards include dividend rights and vest immediately upon grant. The recipients are restricted from trading the restricted stock for one year from date of grant.

A summary of the status of our non-vested restricted stock grants and service and performance based RSUs as of December 31, 2014 and changes during the year then ended is as follows:

Non-vested Shares	Shares			Weighted Average Grant Date Fair Value
