8. | EQUITY:
Exchangeable Shares and Series F Preferred Stock In connection with the acquisition of Valard on October 25, 2010, certain former owners of Valard received exchangeable shares of a Canadian subsidiary of Quanta which may be exchanged at the option of the holder for Quanta common stock on a one-for-one basis. The holders of exchangeable shares can make an exchange only once in any calendar quarter and must exchange a minimum of either 50,000 shares or, if less, the total number of remaining exchangeable shares registered in the name of the holder making the request. Quanta also issued one share of Quanta Series F preferred stock to a voting trust on behalf of the holders of the exchangeable shares. The Series F preferred stock provides the holders of the exchangeable shares voting rights in Quanta common stock equivalent to the number of exchangeable shares outstanding at any time. The combination of the exchangeable shares and the share of Series F preferred stock gives the holders of the exchangeable shares rights equivalent to Quanta common stockholders with respect to dividends, voting and other economic rights. On March 26, 2013, 409,110 exchangeable shares were exchanged for Quanta common stock. Treasury Stock Under the stock incentive plans described in Note 9, the tax withholding obligations of employees upon vesting of restricted stock awards and RSUs to be settled in common stock are typically satisfied by Quanta making such tax payments and withholding a number of vested shares having a value on the date of vesting equal to the tax withholding obligation. As a result, Quanta withheld 374,702 and 289,057 shares of Quanta common stock during the nine months ended September 30, 2013 and 2012, with a total market value of $12.0 million and $6.2 million, in each case for settlement of employee tax liabilities. These shares and the related cost to acquire them were accounted for as an adjustment to the balance of treasury stock. Noncontrolling Interests Quanta holds investments in several joint ventures that provide infrastructure services under specific customer contracts. Each joint venture is owned equally by its members. Quanta has determined that certain of these joint ventures are variable interest entities, with Quanta providing the majority of the infrastructure services to the joint venture, which management believes most significantly influences the economic performance of the joint venture. Management has concluded that Quanta is the primary beneficiary of each of these joint ventures and has accounted for each on a consolidated basis. The other parties’ equity interests in these joint ventures have been accounted for as noncontrolling interests in the condensed consolidated financial statements. Income attributable to the other joint venture members has been accounted for as a reduction of reported net income attributable to common stock in the amount of $5.5 million and $4.5 million for the three months ended September 30, 2013 and 2012 and $14.8 million and $13.0 million for the nine months ended September 30, 2013 and 2012. Equity in the consolidated assets and liabilities of these joint ventures that is attributable to the other joint venture members has been accounted for as a component of noncontrolling interests within total equity in the accompanying balance sheets. The carrying value of the investments held by Quanta in all of its variable interest entities was approximately $8.3 million and $5.4 million at September 30, 2013 and December 31, 2012. The carrying value of investments held by the noncontrolling interests in these variable interest entities at September 30, 2013 and December 31, 2012 was $8.3 million and $5.4 million. During the three months ended September 30, 2013 and 2012, distributions to noncontrolling interests were $2.5 million and $6.7 million. During the nine months ended September 30, 2013 and 2012, distributions to noncontrolling interests were $11.8 million and $13.0 million. There were no other changes in equity as a result of transfers to/from the noncontrolling interests during the nine months ended September 30, 2013 or 2012. See Note 10 for further disclosures related to Quanta’s joint venture arrangements.
