Explanation of Responses:

1. Shares purchased under the Company's 2010 Employee Stock Purchase Plan.

2. Each performance share is a restricted stock unit representing a contingent right to receive one share of CMC common stock. The performance units vest based on certain performance criteria. In addition, after determining the portion of the performance units that will vest, the Compensation Committee of the Company may reduce the number of vested performance units, in its discretion, if the Company ranks below the 40th percentile on a Total Stockholder Return basis as compared to its Peer Group with the Total Stockholder Return based on the average of the closing prices on the principal market for each trading day for the month of December 2010 versus the month of August 2013.

3. Award of restricted stock units under the 2006 Long-Term Equity Incentive Plan. Each restricted stock unit represents a contingent right to receive one share of CMC common stock. The restricted stock units ("RSU Awarded Units") vest and become payable as follows: (i) one-third of the total RSU Awarded Units on the first anniversary of the date of grant; (ii) one-third of the total RSU Awarded Units on the second anniversary of the date of grant; and (iii) one-third of the total RSU Awarded Units on the third anniversary of the date of grant.
