Note K: Stock-Based Compensation

The shareholders approved, on May 23, 2006, the Martin Marietta Materials, Inc. Stock-Based Award Plan, as amended from time to time (along with the Amended Omnibus Securities Award Plan, originally approved in 1994, the “Plans”). The Corporation has been authorized by the Board of Directors to repurchase shares of the Corporation’s common stock for issuance under the Plans (see Note R).

Under the Plans, the Corporation grants options to employees to purchase its common stock at a price equal to the closing market value at the date of grant. The Corporation granted 58,207 employee stock options during 2013. Options granted in 2013 become exercisable in four annual installments beginning one year after date of grant and expire ten years from such date. Options granted in 2005 through 2012 expire in eight years from such date. Options granted prior to January 1, 2005 became exercisable in three equal annual installments beginning one year after date of grant and expire ten years from such date.

Prior to 2009, nonemployee Board of Directors received 3,000 non-qualified stock options annually. These options have an exercise price equal to the market value at the date of grant, vested immediately and expire ten years from the grant date.

The following table includes summary information for stock options as of December 31, 2013:


	Number of Options			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Life (years)

Exercisable at December 31, 2013		732,015		$	105.44		2.3

The weighted-average grant-date exercise price of options granted during 2013, 2012 and 2011 was $108.24, $69.12 and $86.90, respectively. The aggregate intrinsic values of options exercised during the years ended December 31, 2013, 2012 and 2011 were $7,142,000, $7,176,000 and $1,621,000, respectively, and were based on the closing prices of the Corporation’s common stock on the dates of exercise. The aggregate intrinsic values for options outstanding and exercisable at December 31, 2013 were $10,689,000 and $8,649,000, respectively, and were based on the closing price of the Corporation’s common stock at December 31, 2013, which was $99.94.

Additionally, an incentive stock plan has been adopted under the Plans whereby certain participants may elect to use up to 50% of their annual incentive compensation to acquire units representing shares of the Corporation’s common stock at a 20% discount to the market value on the date of the incentive compensation award. Certain executive officers are required to participate in the incentive stock plan at certain minimum levels. Participants earn the right to receive unrestricted shares of common stock in an amount equal to their respective units generally at the end of a 34-month period of additional employment from the date of award or at retirement beginning at age 62. All rights of ownership of the common stock convey to the participants upon the issuance of their respective shares at the end of the ownership-vesting period, with the exception of dividend equivalents that are paid on the units during the vesting period.

The Corporation grants restricted stock awards under the Plans to a group of executive officers, key personnel and nonemployee Board of Directors. Certain restricted stock awards are based on specific common stock performance criteria over a specified period of time. In addition, certain awards are granted to individuals to encourage retention and motivate key employees. These awards generally vest if the employee is continuously employed over a specified period of time and require no payment from the employee. Awards granted to nonemployee Board of Directors vest immediately.

The following table summarizes information for incentive compensation awards and restricted stock awards as of December 31, 2013:
