Employee Stock Purchase Plan

Under the Company’s 2006 Employee Stock Purchase Plan, or ESPP, a total of 1,082 and 848 shares of class A common stock were purchased during the three months ended September 30, 2013 and 2012, respectively, and a total of 2,846 and 2,471 shares of class A common stock were purchased during the nine months ended September 30, 2013 and 2012, respectively. The ESPP is non-compensatory and is intended to qualify as an Employee Stock Purchase Plan as defined in Section 423 of the Internal Revenue Code of 1986, as amended, and in accordance with GAAP guidance that requires estimates in the fair value of share-based payment awards on the date of the grant using an option-pricing model and recognizing the expense over the required service periods in the accompanying Condensed Consolidated Statement of Comprehensive Income (Loss). The Company received $6,414 and $4,053 upon the purchase of shares under the ESPP for the three months ended September 30, 2013 and 2012, respectively, and $17,411 and $15,266 upon the purchase of shares under the ESPP for the nine months ended September 30, 2013 and 2012, respectively.
